[Q] Radio issues following ROM update - One (M7) Q&A, Help & Troubleshooting

Hey, thanks for clicking my post. TL;DR Since updating from ARHD 40.3 to Viper One 6.2.0, my radio has been having major intermittent issues. I have a HTC One m7_ul unlocked outright from Optus here in Australia. It is as of right now running the latest firmware linked to by the Viper One/ARHD threads, the latest TWRP, is S-OFF and superCID, running Viper One 6.2.0.
Symptoms:
1) No signal most of the time.
2) Signal appears to return during periods of movement (e.g. driving).
3) Even at full signal, there is no mobile connection (no data, no text/calling).
4) Once every few hours, when it has signal, it will gain mobile connection for a short period of time, after which it will cut out again - repeat to 1).
Here's a short story about how this came to be:
For many many months now it has been running just fine on stock firmware, rooted with S-ON running ARHD 40.3 (since that version came out).
About a fortnight ago I started noticing issues with my contacts application. Something to do with 501 contact link suggestions and certain contacts having hundreds of Facebook profile entries. This would cause issues in the People app (people just wouldn't load) and the SMS app (message histories wouldn't load, including new texts).
After some troubleshooting attempts, I resolved to reinstall a ROM. I opted to install the latest Viper One (6.2.0) successfully. It resolved my issues. However, it introduced a new one. The next morning I woke up to 4 texts from my service provider informing me I'd missed calls. I had no notifications as such, so the calls never reached my phone. I put it down to tower signal flex in my area. I left and as I walked out the door I noticed I had no signal (no bars, x above the icon in statusbar). Driving around seemed to fix the issue though, it got back up to normal values quickly enough.
However, even though I had plenty of signal and mobile data was ostensibly turned on, I couldn't get internet. I tried sending a text to myself but it failed send. Calls out simply waited on signal and then timed out. Every single other function of the device is 100% AOK (wifi, bluetooth, nfc, etc). The entire ROM is fully functional, can't find any other issues with stability or otherwise.
I put up with it for the day and get home and start troubleshooting. Here's what I tried so far, in order:
1) Change from Viper One to latest ARHD (71.1). Installed with no issues. Booted phone, no dice - no signal.
2) Checked SIM by moving to old iPhone 4 - full signal, radios work. It's not a service issue.
3) Revert to last known working ROM - ARHD (40.3). Installed with no issues. Booted phone, no dice - no signal.
4) Research research research. Think it might be a problem with firmware perhaps. Tried revone, failed because I'm not on 4.2.
5) Flash MaximusHD (11.0.0) in order to make use of revone for S-OFF/superCID. Flashed latest firmware linked in Viper One/ARHD threads.
6) Reboot phone. Still no dice with latest firmware on MaximusHD (11.0.0).
7) Retry with latest ARHD. No dice.
8) Retry with latest Viper One. No dice.
In every single instance, all the ROMs are fully functional except for mobile signal - wifi, bluetooth, nfc, etc. radios function perfectly. No issues with ADB or fastboot during any step of these processes. All my device info shows what I expect to see. I've searched as much as I can, to no avail. I turn to first-time posting here as a last resort to maybe find out what the issue is.
I am slowly reaching the thought that the hardware itself might be the issue. I'd appreciate any insight into what could be causing this - be it software or hardware - as well as if there is any way to test or diagnose the radio physically. Even just a confirmation ("Yep, sounds like your radio's FUBAR"). In the meantime, I'll be using aforementioned iPhone 4 (ugh).
Thanks for reading.

Have you attempted to flash a different radio baseband?
Look up the radio version used in ARHD 41. If you find it, search for the radio within the forums and flash it. You can still keep the most current version of your preferred ROM. Search the threads for how to flash a radio baseband, there are plenty of them.

I found a forum for HTC One radios here, it's in the AT&T section but apparently work on all HTC Ones. I was unable to find out which radio ARHD 41 used, my understanding is that custom ROMs don't usually come with a radio baseband of their own and they don't appear to list any on their thread that I could see. I would inquire but I think there's an issue with new users posting in development sections. Do you think it's worth trying to look further into what radio was used, or should I start flashing radios from the aforementioned list? There's a couple that stand out as possible candidates (the earliest version, the newest version, etc) but I'm not sure I want to just start going crazy on that list until something works. Or do I?
edit: To clarify, and they say explicitly in the ARHD post FAQ, they do not include radio/hboot/firmware in their ROM. So I must assume that I was simply on the stock radio the device shipped with.
edit 2: Confirmed my current baseband matches one of the ones indicated as installed from firmware package. I'm not sure what it was before I updated to Viper One or even while I was using Viper One.

Flashed the earliest radio baseband available from the aforementioned thread. Put the SIM back in, signal achieved, able to send texts/make calls/USSD codes. I was unable to get it to transfer mobile data, however.
Can't believe I didn't think about radio baseband. Didn't even know that was a thing. I just thought it was part of the firmware package. There you go I guess. Thanks again for the tip.

No problem, just remember that if you're having issues with certain partitions on the device, each partition is technically flashable if you are S-Off and SuperCID.

I've tried just about every radio in that forum. They all seemed to have the same issue for me - at first it seems to have no signal, then it gets normal signal, receives/sends any buffered texts, and then fails to work after that for any purpose regardless of signal. I think I'm back at square one; I don't suppose there are any other simple things to try?

If you are having issues still, the other alternative is to flash a different firmware version than what the ROM provides. Firmware and radios tend to "talk" to each other in certain ways, so maybe your firmware isn't using your radio the way you need it to. Also, make sure you are installing firmware particular to your device. For instance, do not install firmware originally meant for an AT&T phone if you use Verizon or another carrier. They tend to write the code particular to these things. I would do some research through the forums and see if you can find a good combination in your area that people have tried. Maybe even a Google search will help out if the forums seem daunting to dig through.
And don't forget, the iPhone has a Quad-Band receiver that's capable of receiving cellular signals much clearer. The HTC One, in my opinion, does not match hardware compared to the iPhone. The iPhone will always technically be superior, no matter what opinions people hold to both.

First, thanks again for your patience and assistance.

I was not aware of this restriction. I suspect I may have flashed firmware for a different region. I isolated the Optus firmware RUU numbers and got a firmware package matching, and the android-info.txt matches the device original CID and modelnum. I'll try it soon.
I'm still having trouble understanding, though, how it could have failed in the first place. My phone was S-ON when the radio stopped working; surely changes to firmware/radio couldn't have occurred anyway? None of the ROMs I've touched have firmware or radio included as far as I could tell.

Flashed the firmware appropriate to my region (4.20.980.1). Came with radio. Rebooted, put in SIM, no signal for 5 minutes. When I get signal, texts don't send and calling times out, USSD codes give connection problem errors. Same as before. How likely is it the actual hardware could be damaged? I did drop it on concrete, on the front of the device at the top, around the time this started happening - very shortly before I flashed Viper One to fix the contacts issue. There was no visible damage.

Quick question:
Are you installing your firmware and software without the SIM card in? If so, I would leave the SIM card in and have all the software installed during the process. Damage to the phone should not cause problems for connecting to the cellular network. Have you tried leaving the house, going outside, or getting into a different area to try your signal? Maybe your house is a deadzone and the phone is having a hard time picking it up. My room gets like this since I live in Florida where houses are built with cinder blocks to prevent hurricane damage. It really messes with my signal.

Good ideas, but unfortunately not - every firmware and radio package I've flashed, I've done once with the SIM, once without, thinking along a similar line.
I'm in a known good cell location - coverage in my area is fantastic with my provider (Telstra, usually get 5 bar signal on 3G - I do not get LTE on my plan). I test in multiple places - next to my PC, outside the house, down the street, etc. The behaviour I've noticed is that I have no signal regardless of where I go, for about 5 minutes after booting the phone, after which it gets signal, sends/receives any buffered texts, and then fails to communicate successfully after that (i.e., I get the test text I sent myself, then I resend another test, and it fails to send). The iPhone 4 I've been moving my SIM to has been receiving full signal (as expected) at every place I've been testing the HTC One.

Hmm...
You might have to go into your APN settings to change some things in order to get it to work properly. Go to your Settings, then Mobile Data, then Access Point Names. From this menu click the current APN saved with the phone. After that, it will have you insert some information. Check this website for the specific APN information for your carrier. Make sure it's for your carrier as there is a large list of different ones on there.

Other than that, I honestly couldn't tell you what your issue is.

Tried the APN thing. There was indeed a few things different from the listed settings, but honestly, they were pre-populated with a bunch of Telstra data beforehand when the SIM was in. I made the changes and noticed no difference.
Thanks again for your help. As a last step I will return it fully to stock. After that I suspect my only recourse would be taking it back to Optus and asking if they'll quote me to fix it.

Unfortunately it does seem to be hardware issue from the history of what you have tried and posted.
Use nkk71's guide listed in my signature to go back to stock for warranty but substitute your local RUU/nandroid/etc.

Thanks for the link, that's actually one HTC One return-to-stock guide I haven't seen yet and it looks very concise. Cheers.

Sorry about that, I know having a custom ROM is a lot of fun, but there can definitely be some cons along with it.
Good luck with your phone!

Any info on Checking Band priority? EPST?

As some of you may have read, my phone is somewhat hosed.
I have a new one on the way (which might be a refurb). But I have nothing to lose playing with this one.
I highly suspect, one or more of the bands are disabled.
If you google around you see lots of folks fiddling around with Band Priorities and/or Enabling. Especially with "TirBand" phones (which this is). (Nexus 5 and HTC One, HTC One Max).
Most of the time people access this through EPST using ##4636# but my phone does not respond to this.
But the Galaxy S5 and HTC One (M8). Are in new Territory with Spark and even more bands I believe. So their might be new Menus for these phones and that info has not been leaked out yet.
Currently if I'm in a formally strong 4G area I get great 3G (no 4G at all). Yes 4G is enabled.
If I'm in Moderate to Weak 3G area. I get 1x or nothing. It really feels like a Band got shut off.
I'm not sure what caused it.
I was running Corporate PRL (56018). That seemed to not be causing any harm. Ran it for a few weeks.
Ran Barebones 1.0 (on stock firmware) and that ran fine too. After that it was down hill.
My only issue was Roaming Guard was on and Locked out. Which others have reported is a long standing issue (was a problem on M7 too).
All I needed to do was do a Full Wipe and enable it before it gets locked again. Not everyone has this locking issue, but MANY do.
I updated to OTA firmware. Not sure of status here because I had WIFI on normally.
Then I decided to run BadBoys Harman. Without firmware. Again not sure of status here as WIFI was on.
Somewhere I believe I did an Update Profile. I suspect at that point I was hosed.
It was when I put BadBoys on that I noticed an issue because he shows when you are on 1x.
Not sure if I started to see 1x that was before or after update profile.
I don't know if it's combination of having been on the corporate PRL when I did the update Profile or what.
I always try to do update Profile over mobile network.
I was not clear what the problem exactly was until I "Fully" upgraded (Harman with Harman firmware).
Just to be clear, I'm not blaming anyone but me. And there may be nothing wrong with anything out there than more or my phone. I just don't know.
I highly suspect it's something trivial that got turned off or the phone so happened to lose a band or antenna.
But I suspect it's some combination of SuperCID, Corporate PRL, new OTA Firmware or Harman Firmware along with Update Profile hosed me.
I do have new phone on the way. But I sure would like to know what happened.
I didn't do anything "out of bounds" from this forum. I simply may have done things in a different order or something.
I am S-OFF and running TWRP 2.7.0.2
I have reactivated, wiped the gazoo out of it. Ran Harmon RUU. etc.
I sure wish there was an RUU for the Shipped Config. Or even for the OTA version.
Seems a coincidence the phone "Broke" just when I started Flashing Firmware and Updating Profile.
I know I was good on Stock Rooted, S-OFF, Corporate PRL. Because I'd even see 4G at my house occasionally which is a reach. Now I'm lucky to get 1x at my house.
I will tell you this, I'm staying on Stock Firmware and Stock PRL when the new phone arrives until more is learned.
I will try to compare phones as best I can.
Which is another reason I sure would like to see the Band configuration on this phone so I can compare it to the new phone.
Thanks for any tips.
I think you were trying to do *#*#4636#*#* to access the Menu. The EPST command would be ##3282#.
I'd be interested in your comparison. I think I may have a hosed phone as well. I have it on cdma only and I'm constantly losing data, dropping calls, and missing calls in places I didn't before. The only roms I have flashed are Captain's 1.54.651.8, and my BareBones rom.

Thanks when I saw people posting *#*#4636#*#* I stupidly assumed they were trying to get past some HTML issue with ##. *#*#4636#*#* works !!
Turns out when you use the Google Play app called "Advanced Signal Status" when you click "Advanced" it brings up the same Menu as *#*#4636#*#*.
I didn't realize it was bringing up something built into the phone.
Any way,
It looks like on HTC Max it was *#*#3282#*#* which does not exist on HTC One (M8). You have to use ##3282# but that does not offer the same Band settings that HTC Max has with *#*#3282#*#*.
Just a quick reminder that Questions go in the Q&A section.

When and how often have you:
Updated Profile?
Changed Firmware?
Changed from factory PRL?
I think my problems may have started after I flashed Captains Firmware for OTA (which I got the link from you ROM thread).
I'm not saying it was, but it was around that time. It may have been something to do with PRL's but those are usually harmless and very revertible.
I'm 99% sure I was ok on your ROM with Stock Firmware. Except for Roaming Guard on and locked out. Not sure if that is an early symptom of problems though.
Some things in firmware (on past phones) are not revertible (ever !!!)
Your symptoms sound a lot like mine. I only get good 3G in locations where I used to get good 4G. And I get no 4G at all now.
My phone generally works but many calls go to voice mail or get dropped. Or end up being one way (one of us can't hear the other).
I think it's one of these:
Band issue (disabled or low priority)
Some sort of ID issue that got lost (like a lost security Key)
Some of Power Saver issue (i.e. Extreme Power Save kicking in when it shouldn't)
The reason I mention power is it does this.
WIFI On
Running "Advanced Signal Status"
All looks ok.
Shut off WIFI and things go nuts.
EVDO (data) RSSI Signal: drops to -120db (0%)
Then network type switches to 1xRTT from eHRPD.
It's like the extreme power saver is on. Which, guess what, OTA firmware was supposed to enable !!!
I have tried disabling it in settings. But I think something is haywire.
This is what extreme power save does. And came with the OTA update.
QUOTE: Basically it shuts down all connections but still allows phone calls and texts to come through. You can manually refresh e-mail if you want — but only in HTC's e-mail app. Your smartphone essentially is turned into a dumb phone. And to make sure you don't cheat and try to actually make it do things, the M8 gets a new home EXTREME home screen, with shortcuts to the Phone, Messages, Mail, Calendar and Calculator apps. To exit EXTREME mode, you'll need to hit the dedicated "Exit" button.
HTC says that with only 5 percent battery remaining, you can eke out 15 hours in this EXTREME mode. On a full battery? It'll last something like a dozen days. We'd consider this to be more of an emergency mode than EXTREME, however. END QUOTE
It sure feels like this is what my phone is doing. I think it's stuck on Extreme Power Save mode (in the RADIO only).
I flashed the firmware twice, updated prl many times, never changed prl. Sounds like same symptoms.

I highly suspect it's not PRL. When you say "update prl" I assume you mean from settings -> system update menu.
I suspect firmware. Of which there is nothing available to go back to.
Can you get 4G?
I rarely get 4g, it hasn't been fully implemented where I am. I got it on my gs3 only sometimes. And yea, updated prl through settings
---------- Post added at 08:58 PM ---------- Previous post was at 08:18 PM ----------
I'm definitely going to a Sprint store. I was just on Sprint chat and they confirmed it is not network related but a defective device. Dammit.
This is what extreme power save.came with the OTA update.
HTC/Sprint removed the band priority section from the menus in the Max so it's either hidden deep OR it's not there and Sprint is controlling what band you actually use on their end which is highly possible....

Ahh, thanks for the info. I think that's what is messed up on my phone some how. Some Key or ID so it knows the appropriate ones to pick.
I've been switching back and forth on firmware and flashing mainly between Viper Rom and Bad Boyz H/K Rom without any issues at all. I had one issue where I couldn't get data or roam, I temporarily fixed by flashing some stock files, but since a clean install all has been well. I've updated profile and prl quite a few times without any issues so far.
I don't get lte at home, but it worked great in Indianapolis over last weekend. Just thought I would share the info.
Also s-off and super cid if that helps any.

That's interesting you lost Data / Roam and managed to got it back. Perhaps if I had put the dialer on like you did at that first problem I would have got it back too.
So you are running H/K firmware as well?
I've made it as close to stock as I could including recovery. Went to 4G area (where I can get 3G). Factory Reset (from boot loader), Redid Activation, Updated Profile/PRL etc. All worked (albeit slowly).
But still no 4G and no 3G when in normally 3G only areas.
Then I tried running H/K RUU back to back twice. Still stuck.
I may try RUU one more time, then try reactivate/profile/prl again in the 4G area.
Is there any need to change hboot? I have left what the H/K RUU put on there sometimes and other times used the one posted here that removes the red unlocked text etc.
The only thing I've messed with on hboot was the mask to remove the tampered text and red text on boot screen.
Yeah I was the one that sent you the message about losing mine until I flashed stock phone apk. But you said it didn't work for you though. But after I did a clean install of the Rom I haven't had any more issues luckily. Hopefully your replacement will work a lot better for you. Maybe just got a bad phone hopefully.
Yes I'm back on H/K firmware again. I went back to old firmware when I flashed viper a few days ago.

[Q] Phone Roams All The Time

My phone out of nowhere started doing this really fun thing where it drops to roaming at random. From what I can tell, the phone is not making a handoff to the next tower to avoid the roaming. For example, if I'm sitting under a tower with full 4G, everything is fine. If I have 2 bars, it will work in 4G for a while before dropping to 3G roaming. I am able to force it back into 4G by dropping in and out of Airplane mode.
I'm running the official CM11 4/30 nightly (I was on the March Snapshot until this started happening).
First I used some Google-Fu and found it's most likely a bad SIM. I swapped SIMs with my wife, she was stuck in 3G roaming, awesome! Went to Verizon, the switched the SIM, all good, right? Nope, I didn't notice it right away, left the store and thought all was good until I needed to use internet at work.
Next, I thought it was software, so I created a backup, and dirty installed the newest CM11 nightly. No change, so I did a full wipe and install. No luck.
So next I thought maybe the radio was corrupted, so I tried to update the radio, which didn't go so well. I got stuck in a boot loop and had to sideload the old driver and reflash. So I'm back up but still having this problem. I'm thinking my only thing I can do at this point is to go to stock and see if the updated radios make a difference.
I saw another guy is had the same problem, but he had his phone replaced. I'm not sure if that will work for me since I purchased via Swappa (I do have Asurion insurance though).
So what help do I need?
1) Does anyone have any ideas on what I can do to fix this?
2) Are there any good instructions out there for how to flash to stock?*
3) Are there any good instructions on how to re-root and flash back to a custom ROM once taking the newest OTA?*
*Most of the instructions I've found have been pretty confusing and use a lot of acronyms without explaining them. I'd be willing to write some cleaner instructions for a sticky if someone would be willing to help me out with any questions I have.
Thanks everyone, I appreciate any help offered.

I'm fairly certain it's hardware. I spent a day using my Galaxy Nexus - full 4G the entire day.
I went back to stock, "bricked" my phone about 3 times doing it (quotes because it was salvageable, but I had a couple hours where I was googling like a madman worried I dun ****ed up). Stock and the new radios made no difference. In fact, with stock it would only go to 4G if I restarted it - airplane wouldn't even bring 4G back. Figure that one out.
I went to the VZW store and I'm basically screwed. I can call LG and see if they'll replace it or use Asurion. Since I got the device off Swappa, they cannot replace it. They tried to order me a new one, but the system wouldn't let them. I don't really have time to call LG, so I'm probably going to Asurion it. Their process is stupid simple to do and they'll have a phone to me the next day. Then I can spend all day tinkering with it and getting CM11 back on, which I feel like I'm an expert at right now.
Sorry, wish I had better news. If you got the device from VZW, go to the store after flashing to stock. They might want to try swapping your SIM first though, so make sure you go to a store that has decent 4G coverage in its surrounding area.

Thanks dude. I think you are right, flash stock and get a new sim first. I have a hard time believing its a hardware problem. I just wrote this in the other post about roaming:
"Same exact problem here. I was on the phone with Verizon last night. I was running cloudy pro 2 (all his roms for that matter as they are international roms) and kept getting the roaming issue you speak of...with 3g. I went back to 11A completely bone stock. Just like you mentioned, I get 4g but then after like 10 minutes I get 3g with roaming. Of course this is after I spent 30 minutes on the phone with tech support. They 'zapped' my sim card and it appeared to work but no dice. Now before doing all this I downloaded build prop editor and changed the ro.build.target_country to US versus COM as everyone suggested in all the forums, still no dice. I've tried the toggle airplane mode trick...works for like 5 minutes and back to 3g roaming. I think maybe a new sim card and avoid international roms...bummer because cloudys roms are blistering fast. Interesting thing though, I installed xdabebbs rom and malladus' rom, after already running cloudys roms, and get 3g but no roaming. I also verified that Verizon wasn't throttling me or something like that. One more thing I tried is reflashing the basebands and 24A modem, no dice. If there is a build prop fix or some other fix I'd love to hear it.
Edit: One think I'd like to mention. When I had an S4 I switched between stock roms and AOSP roms and the network settings were responsible for causing the roaming because the stock rom was an older build than the AOSP. So when I had roaming, I'd reflashed the AOSP rom, changed the settings then flash the stock rom. It worked great. "
Edit#2: Ok making a little progress. Just did this:
Get a build.prop editor from the play store, and change ro.carrier to VZW and ro.build.target_operator to VZW and ro.build.target_country to US.
Initially it worked but when I make calls it gives me Unfortunately, the process com.android.phone has stopped and I cant make calls. I went into Settings, Apps, reset app preferences...that didn't fix it either.
4G/LTE is pretty solid now but again, I cant make calls.
Edit#3: Nevermind...roaming again.

Alright, so, I have some interesting news.
I got a replacement device from Asurion - not just a replacement, a brand new device out of the box. I pulled it out of the box, swapped the SIM, same exact issue .
I went to Verizon and *****ed up a storm. They basically said "you bought it on eBay, not our problem" (I actually did Swappa - but they don't know Swappa and they do know eBay).
So I got the guy in the store to do some digging, and apparently Verizon has a point opened up with LG as they're seeing this on more and more devices - especially since KK came out. So I figured I could try an older radio. The device was on 12B when it arrived. I just flashed stock to 10B and it's the same issue. I don't know what's going on at this point - nothing makes sense but its apparently a known issue that's been appearing since the KK update.
I'm going to call Asurion and request a new device again since this one is doing the same thing, we'll see what happens. I'm still leaning towards hardware and thinking there was a slew of bad radios that went out.
Just for giggles - and I have no reason whatsoever to think this will work. I'm going to swap out the new SIM that came with the phone. Originally, I just put in my old SIM since the new one was taking too long to activate. I'm having the exact same issue I had previously. With that, I'm going to leave the new SIM in and see if it has the same dropping issue. The guy in the store had mentioned he could swap out the SIM but after a few days it will crap out again... which makes zero ****ing sense. Because of that, I might as well see what happens if I pop a new SIM in. While again, this makes 0 sense, I'm wondering if maybe the phone is frying the SIM somehow?
Again, it makes no sense at all, but I have nothing else left to try other than getting Asurion to repeatedly send me phones until I find one that works or they replace for another type of phone (which I REALLY don't want). I'll drop an edit in an hour or so if what I try makes a difference.
Quick Edit:
I COULD just keep going to the VZW store and have them repeatedly swap out SIMs since it will fix it for a few days .
EDIT:
Got the new SIM installed and it's working. The guy in the VZW store told me that we can keep swapping SIMs and the same issue will happen, which again, makes no sense to me. I'm at a bit of a loss to be honest. I wonder if it's possible that my old device was frying the SIMs (again, makes no sense) and that maybe the new SIM not going in my old device will fix the issue.
What ROMs are you running? A phone frying a Sim does not sound likely at all. I got my new sim card and have been running xdabebbs ROM with no network issues. I feel like my issues stemmed from the Intl ROMs.

The only ROM I've ever run was CM11.
Same thing happened on stock though after flashing through the LG Flash Tool. Then, with the new phone from Asurion, used old SIM - 3G only. Used new SIM - 4G sticks.

Radio issues on 4.4.2

I am on Kryptonite's Stock rooted 4.4.2
I recently moved from the midwest to the east coast. Before my move I had fantastic coverage in places VZW didn't even advertise as covered. I visited my new home in PA several times, and had great service the whole time. Skip forward to a month ago, I moved permanently to PA, and since about a week after getting here I have had nothing but trouble. I will often lose service altogether, but most of the time I have 3-4 bars of 4G.... but no calling. I get "Mobile Network Not Available" and incoming calls simply ring until voicemail on their end, with no indication I'm getting a call at all on my end.
I have reflashed radios, done a factory restore of the ROM, swapped SIM cards with my wife's phone (Droid Ultra, stock NO issues at ALL) and nothing seems to fix the problem. I'm not sure what to do next. Does anyone have any ideas?
Edit: imei.info shows my phone's IMEI as a Droid Bionic.... I have never owned a Bionic?

Use RSD Lite to flash the entire VZW 4.4.2 SBF, which includes modem, and all partitions. See if your issue persists. If solved, then try flashing Kryptonite and see if the problem is still present.
Ignore the data from imei.info - their database is less than perfect.

I tried a new SIM card (at Verizon's request) and no dice. I haven't tried an SBF yet, although I did flash the new version of Kryptonite's ROM. If I sbf will I lose disabled write protection?

Yes you will absolutely lose wp-off. Only other option is to flash entire 4.4 sbf, repeat the root/wp-off exploit, then install safestrap and flash the kryptonite rom again.
Alternatively, you might try flashing just the radio. I suggest asking in ikryptonite's thread. I believe he has the proper radio available to flash via fastboot.
Good luck
I bit the bullet and just SBFd anyway, and still not fixed.
Is it a hardware issue then?

How do you fix Not Registered On Network?

So as of saturday my unlocked TMobile Note 4 stopped working as a phone, and won't let me make calls.
Information:
-Was on Dr. Ketan L3 version of his rom when it stopped working
-Using the N910T on AT&T
-IMEI is fine and not damaged, both numbers match (using *#06#)
-It shows bars, but when I go to make a call "Not Registered On Network"
What I've Done:
-Flashed Stock Firmware via Odin (Autoboot, and F.Time Rest checked)
-Factory Reset after odin flash
-Checked APN
-Set on LTE/WCDMA/GSM
-Searched for Networks, finds them, but when I choose AT&T it takes forever and then finally kicks me out and then in notifications, I get the "Not Registered to Network"
-Did the remove the battery thing, and removed sim
-Went to AT&T and got a new sim, worked for 1hr (sporadically) and then went back to "Not Registered on Network"
-At the store I was on phone with AT&T tech trying to troubleshoot the problem and that is when it was working shortly
-Called T-Mobile and checked to see if they blocked my IMEI number, nope they didn't, couldn't help me out further than that
-AT&T was showing that it was a Note 4 so not having that coming up as a Blackberry issue that some reported, so that's not it
-*#0011# shows service limited, but it is unlocked and everything is fine, the IMEI is good, and all is well but the limited service
-Put it in Airplane mode and woke it back from there after 5+minutes
-cleaned the connectors on the sim (new sim anyways so shouldn't really need them)
I'm running out of options, the only thing I can think of being the problem is that I might have started out using this phone on COD2, and when I flashed a COG2 firmware it didn't like that and so my phone's account settings didn't fully transfer.
Also I was messing around with the bands settings (*#2263#) what should they be on? Automatic, LTE/GSM only, or what?
Settings should be on automatic. One more thing to try is go for a drive with the phone, at least 5 miles from your house, and see if it does this when connected to other towers. I had this same issue years ago and it turned out to be a malfunctioning tower by my house.
If it still does it on other towers, then it may be hardware-related

Thanks, yeah it kicks in randomly for like a minute and then dies, I take it to my parent's house (about 10 miles away) and along the way I get a good signal, but then when I reach their house, back to nothing. I was using it just fine the week prior. I partially blame Dr. Ketan, ever since installing his rom, I had multiple issues. I since uninstalled it and tried going back to stock. Any idea on what a good "safe" band setting is? I have that settings set to automatic, but if there was a good "safe" band that would be great. A common LTE tower. Even when I do connect or get connected, I can't register on that network, my phone won't let me. I've tried that. The bars drop to zero. I damaged my antenna wire (white one) and I just replaced it with a new one I purchased, but the hacked together one seemed to be doing the same quality job as the new one is. It shows the signal, but as soon as you try tying it down to a network it rejects it. I was afraid that when I flashed the stock image via odin it removed the unlock, but it was still there. I just hate that now I have a $500 pda, when it was a phone and now i'm relegated to using a f*ing flip phone.
i think your antenna cable is damaged. the only way to know that is be close to a tower, and see if your work or not.
bought and replaced with new ones, I get full bars, in my bedroom, but apparently they're tied to Tmobile since when I try to register it to AT&T they magically disappear, but when I close the app, they come back at the same strength level. I can't register them to Tmo since the sim. Yet my phone is telling me it's unlocked (*#0011#), IMEI = PASS, 1;
I think the prob is due to the different frequencies.
Your baseband would not be tied to a rom(ie Dr Ketan) Unless that rom contains Modem.bin
Your apn needs to be att if that's your Sim obviously.
International version has a different chipset. .. I know it's not your case. .
But it's open to any Sim. ..
I can say this.. I have a N2 unlocked (tmob) I run an Att Sim it works but the sig is really spotty... COD6/ COG2 may not be lining up frequency wise with your att Sim. ..
Try rolling your baseband back even further. .

Any clue on to what i should use for best results? Like 850/1900 or 900/2100? What is a good LTE band? Where could I find a map of LTE bands used by carriers, I know how to get to that secret menu and manually change it to see if I get better results?

Well I would think automatic is out for sure.. the other prob would be after reboot the chipset will search for the default.. but I could be wrong.
I do not know what the numbers would be for band identification.
You may get lucky when calling Att and ask for someone in a higher tier. To give you some numbers for frequincies .
But you have ruled out hardware correct??
By putting a tmob Sim in????
Cuz I know you posted you did antenna work..
And I do know you said you get bars then it fades..
The fact it fades and doesn't lock into even a G band for example. Just leads me to believe the apn can't lock down based on the frequincie and the built in lte chipset...
It would be nice to just flash an att modem wouldn't it?? But don't even think about it.. lol you'll soft brick..
I wish I had a better solid answer you. You may just start testing those different bands and see if you get closer to a lock.

My Tricked Out N910P
But what could have happened that made it crap out like that since it was working just fine beforehand for 2 solid months on custom roms and what not? That's the frustrating part, I've been flashing different modems on my phone, but none have been successful. Apparently there are 3 different N910T, how do you know which ones to play with? I flashed N910T(3) bands, that failed, I did try N910A, obviously failed. Then I lost my IMEI number, got terrified, tried reflashing EFS in TWRP, nothing. Then reflashed COG2 bands, it came back. Is there an app on the Playstore that would definitively tell you if your network chip is damaged? I wouldn't know what to look for.
Have you taken apart the Note 4, what are all those contact points, are those antenna things? One of those were damaged, they're like folded metal spring boards with gold tips (same kind of thing that is used to install a qi receiver, same design). I took my tweezer and fixed it, but could that be the culprit, since on the surface, it seems like the network is fine. Works really well in WCDMA, but not much else. I was able to make calls using GSM only, but my signal was 1 bar and the audio quality was questionable, so I left it alone for 10 minutes on that hoping it would force a reconnect. This is frustrating, since I wasted $500 on this phone and not having it work after two months means now I'm back to a featureless phone.
Thanks for your advice thus far. Flashing different modems hasn't been working out well, I just wished I could remember what baseband version the guy had the phone on when I first got it? I thought it was COD6, it was definitely on Lollipop, but if it's a 910T(2) would I know, how would I know?
How do you flash NON_HLOS and modem.bin at the same time in Odin? I know Modem does bands, but what does Non-Hlos do? I thought i read LTE, so if those aren't in sync and on two different versions could that be the issue? I extracted them from the full TAR firmware files.

Heres
A simple method for COD6
And try odin 3.07
I need to think about this some more and get back to you...
This is a partial firmware.. it consists of the modem and bootloader COD6.
Also to rule out damage if you can get a T Mobile Sim put it in the device and see if it locks down a signal....

That was my next move, not having any real income but disability and little coming from that, I thought that was the next logical step too. I'll get a tmobile to go sim and try it see if it can't lock on to that, and see if that doesn't set it on the right path. Have you heard of other people having COG2 issues on AT&T unlocked? Maybe that was the problem, something there broke the connection. I don't know, but whatever it is, I can't thank you enough, you've at least given me more options to try that I couldn't think of on my own. I'll try that file.

You are the first of this kind that I'm aware of.. in regards to this issue..
Make sure you read the detail in if your device bootloops, to reboot recovery and flash the Rom.. if you want flash the Rom in the op that I've linked you to.
Wipe sys/dal/cach/data..
And flash it can't hurt.. [emoji16]
I really hope a Tmob Sim and or COD6 gives you results...and good ones at that.. [emoji2] [emoji106]

Got the sim card, $65 for that crap, and it didn't work. Called T Mobile customer service, explained my situation and how I was calling on another phone on another carrier and they insisted on calling me back on the broken not working phone. I guess I'm just screwed, and lost $500, which like I said, I can't afford to have. It's just so frustrating. I also tried the COD6 partial firmware, and nothing there also. I'll try t-mobile again. The only and last option I have, if possible, is to try to relock my phone and re-unlock it since there isn't any real way to tell if my GSM is damaged. I think my unlocked status got damaged when my phone upgraded to COG2, and since it's in that weird limbo state I can't use my phone. Do you know how to relock it?
Edit: When I look at my IMEI Number through *#06# it shows that the last two digits (independent of the actual IMEI number, since that matches everywhere) to the right of the "/" as 14, yet through "about device" it shows my imei version as 10. I assume that the 14 in the "06" screen is the version it's reading off the phone, could that be causing the issue? How would you even fix that? I don't know. but thanks again, you've been helpful.

M7 losing cellular connection frequently! What is going on?

Hi everyone,
This is a great site with a mass of info! I've used it before to flash my HTC Sensation a few years ago.
Since then, I've had a HTC One X and now a HTC One M7. Ok, the M7 is 'New' (from China). It's in excellent condition and it actually does appear to be new. So I don't really know what's going on there... But anyway, I'm having issues.
The phone can't seem to keep a cellular signal, but Wifi is absolutely fine.
So a bit about the history of the phone; When I got it, it was on Android 4.4.2 IIRC with super CID already done. I unlocked the bootloader and flashed LineageOS onto it - the latest one. The battery life was appalling and it wouldn't charge. The phone signal kept dropping.
I've reflashed it today with an RUU called "RUU_M7_UL_L50_SENSE60_MR_BrightstarUS_WWE_7.17.1540.51.exe" and battery life appears to have improved somewhat.
However, the cellular signal keep dropping. Now, I've contacted Virgin UK and explained the situation and they have said the Sim is faulty and it's old apparently and not 4g. They've since sent me a new 4g sim. I've put it in and activated it yesterday.
I still don't understand why my signal keep disappearing.
I've checked and verified the APN details - They seem correct - "Virgin Media Mobile Internet".
The problem appears to be something to do with "Network Mode" or "Network Operator". Sometimes I've noticed that if I go back into the settings and change the selection, sometimes it seems to see the connection again!
Right now, I've selected "2G/3G/4G auto" network mode with "Virgin 2G/3G" as the operator, but I think that soon, it will drop again!
Does any of this sound familiar to anyone here? Thanks, Antony...
Ok, I've just lost signal now, around 2hrs later... My phone has just been left in my house... I've been checking on it every so often.
If I go to "Network Operators" and choose Virgin, it magically works again!
I have full signal again, calls work and internet works. What the?!?!
It's still doing it.
Apparently, it's because I've got a 3G plan but using a 4G sim. Although, that is strange because even if I choose 2G/3G, it still drops.
Mehhhhh.

Can you post a "fastboot gervar all" output please? You have superCID, which means your phone is, or was s-off at one point in time. Maybe you need to flash a different RUU to get everything working

Hey, thanks for your reply!
Since that last post, I've flashed a UK ROM and it was still the same, in a way worse because it dumbed down some options in network settings. I've since flashed it back to the ROM mentioned above. I've now noticed that the problem is something to do with 3G/4G. If I change the network provider to 2G ONLY, the phone works perfectly with my Virgin SIM.
I desperately want to fix this. My new provider which I've switched to doesn't offer 2G, so I'll effectively be screwed.
Here is the data which you asked me to get!

You flashed US unlocked RUU, but that should work fine. You need x.xx.401.xx for WWE, but, as I said, US unlocked should work fine. I had a similar issue with an AOSP ROM, and I resolved it by manually entering my APN settings. Even though all APN settings looked fine, there were some small differences that caused issues. Not a great help, but you could try it, no harm. If thadoesn't work, it's most likely a hardware issue

Hmmm, ok, thanks. I've already messed about with APN details lots of times.
Ahh well. It seems that this phone is doomed. Maybe I'll just have to buy another.
I'll just give it one more go.
Thanks, Antony
