Dangers Of Messing With Your Phone

Hello, everyone, I'd like to share my experience, get any help if someone can, and warn some future people.
So a few months ago i rooted and ROM swapped my HTC one. It was great, I loved it, it was fast and simple.
I tried to change the ROM on it the other day and everything went down hill form there. Basically I ended up having no service and everything else seeming to work fine. So after spending an entire day trying to fix it with BD619, i had to call my carrier today. Now i have the sprint phones, and the sprint service, but i have Credo as a carrier. God knows why. They essentially gave me nothing saying my phone must be bricked and they can't help me.
One thing they did try however was to have me put in a ##xxxxx# number, and there i saw and could edit my MDN and MSID, instead of showing my my phone number and the MSID number they both had "No" written. So he had me edit it and put it in, but when i click "commit changes" it said "commit failed" so if anyone knows anything about that or could help me there, it'd greatly appreciated.
Lesson is, even if you think you know what you are doing, and are careful, weird stuff can happen, and if you have an Odd carrier version of an already less support model of phone (the sprint version), then be EXTRA careful.

Have you tried simply running the latest RUU and reverting it back to stock?

Yes, twice

This is not an uncommon problem but it happens with certain HTC ones and not others. I have helped a few other people with this issue. Most likely, your current ROM is set to RUIN/SIM in Settings-> More-> Mobile Network -> Subscription settings. It needs to be set to NV. If you can't get to this setting, you need to flash a ROM that has the setting available. CM 10 based ROMs all seem to have it. If your phone does not automatically reactivate, you can flash to a stock ROM and use the handsfree activation function and that should get you back up.

Okay so i just flashed a CM 11 build. and Holy S*** I have ******* service! I cant make calls, it says it's not authorized. And i don't see the option you were talking about, in mobile network, i see , Data Enables, Data Roaming, Preferred Network type, System select, (then grayed out) Access Point Names and Network operators, (then not grayed out) carrier settings. When i click carrier settings it says "Unfortunately, the process com.android.phone has stopped. and it takes me back a screen.
where do i go from here?

Try flashing a CM10 ROM. I've always seen the option there. The kitkat ROMs I have used do not have the option except for the Nocs GE.

The only way something like this happens is one of two things.....
1. Ur a noob
2. Your a dev and your testing ril on your rom
The only way to fix this which is a cleared meid of some sort......flashing cm10.1 is the only way and aquiring service by switching to nv....once there everything is fixed just flash/restore back to your rom.

i'd kinda like to argue a point here as this just happened to me. i am certainly not new to flashing, starting back with the mogul and having almost every sprint smart phone since then unlocked (windows) or rooted (webos and android).
Using TWRP and previously running ecliptic 4.3 i wiped caches, system and data then installed the 4.4.2 from team d3rp and voila... no service no meid no nothing.... yes i have the latest radio on my phone.
i guess my point in this is that there's a number 3 that you didn't mention.
3. sh!t happens and it's not n00b related.
for anyone else that has this issue... flashing CM 10.1 worked for me. i didn't even have to set up anything, it just picked up signal. so i rebooted, wiped and nandroided back to 4.3 and all is well.

Did you flash a rom that was meant for another carrier?

I didn't... it was SuperOneK. i'm certainly not blaming the rom though. especially not when others are flashing it fine. the ONLY thing i can think of possibly happening is a bad download. I was in a rush and didn't check the md5.

I had a similar problem when flashing miui. Nothing worked. Even went back to a sense backup and nothing worked.
Commit failed as well.
Here's what I did to make it work again.
Flashed cm10. Change the network settings for CDMA. (Boom it SAID I had service..but didn't).
Rebooted a few times (probably not necessary).
Flashed a sense 4.3 ROM that was close to stock.
Update msl and all that. Commit.
For me..changed LTE/CDMA to just CDMA (no 4g in wv).
Boom it worked again. Hope this helps!

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

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.

[SOLVED] Phone network issue

Hello everyone,
Informations
Phone : Nexus 6
ROM : Euphoria OS 1.0 with included kernel
I have a little problem with the phone network...
I have just install the ROM (3days ago) and everything worked fine.
After the first reboot, I had a network problem: no more network (just phone)
Bluetooth is OK,Wifi also ect...
No extra apps installed.
Any idea?
Thanks
Edit : French phone/network (FreeMobile)

I am having issues over here also. My data randomly stopped working on my way down to memphis, randomly would start to work again. I tried a new rom, it slightly got better, but would cut out of data every 5 min. Kinda got it better by switching to tmo in the apn's. Now just installed sinless, and it is no longer working again.

So, same problem and no fix...? :/

Holy cow! I thought I was the only one! I mean this problem really sucks(and I have wasted a lot of my hours trying to fix it), and have been thinking of creating a thread on this problem until I saw yours.
Okay let me start with what I'm on:
N6: 64gb blue
Rom: Stock
Rooted: Yes
Any other modification: No, only think I did was unlock and do chainfire su root.
Network: VZW
I have had this phone since Dec with no issues other than random reboot every so often.
Now to the problem I had, I went out to the middle of MO for a weekend get away (on Feb 14th). The whole time I was out there it showed 1x even though I was still getting LTE speed. Didn't think much of it until we moved further into the hilly parts of MO were I lost service. Thought it was just where we were at, and thought it would come back once we got back to the hotel we were staying at. It never did. It would say "No Network found" only allow 911 calls.
Spent the next 4 days working With VZW with several trips to the store, and talking to tech support. They made sure my IMEI was not blocked on their side. We used several sim chips, they would all do the same thing, quickly connect then disconnect and go back to no service.
So I did a factory reset, still didn't help. I finally did a fastboot flash of 5.0.1 stock again, this fixed the issue. Until I used titanium backup to restore my sys setting. Then it would drop and not reconnect after the reboot. So I did fastboot flash again and it hasn't happened again since last Thurs. I just restored my app's again to make sure it wouldn't fail to connect over the weekend, and rebooted several times. No issues so far, but I called Motorola and they are RMAing me a new one, because I don't have any trust in this one anymore. They are out of 64gb ones, and they will get back to me in a week.
Questioned to anyone who has gotten a RMA from Motorola:
Are their "like new" replacements okay? I got a few from them when I had my droid x, and they were crap. So I wasn't sure if that is still the same for the N6 or not. I have a feeling its not, but just wanted to get other peoples input on that process.
Thank you for creating this thread, and for everyone's time!
Edit: Had the same issue network wouldn't work, however WIFI, Location, Bluetooth would.

Check your APNs..... make sure you are on the correct one, and that both of APN protocols say IPv4.
Sent from my Nexus 6

APN is for Internet(3G) and MMS, no?
Because we have a phone network (call & SMS) issues.
On my side, APN are OK, but still don't work...
Edit: New !
Everything works fine on :
- Paranoid Android 5 Alpha 1
- Chroma (Latest)
But not work on :
- Euphoria
- Stock ROM
Edit 2 : It works now !!
I seen that I had several issues around the APN side. I mean, I can't add APN, sometime I can. Sometimes APN reseted themselves, sometimes it was OK. Then, I had read the solution above: security tab.
I had just remove my 3rd party lockscreen (HiLocker). Restart the phone and voilà ! After the reboot, my phone ask me the pin code, and all APN are here.
I hope it can help...!

Some times I will see the APN settings, and sometimes I won't. Right now I don't. When it does show up it shows VZWINTERNET selected. There are ton of other options, but they don't work either when the problem was seen.

Is what your experiencing data going in and out? I'm on Sprint and I thought maybe it was just an issue with Sprint. I have or need to read up more on APN because it does get bothersome. I even have issues where sometimes my SMS gets hung up for minutes in sending mode before they actually send. Would be nice to have this corrected.

No my whole problem was that it would drop and no matter what I would do wouldn't reconnect to the network. I tried a lot of things to fix it (see above). APN would appear and then disappear from the menu. Right now its working on the network as of last Thurs. and APN options is not there.

The APN option will not show for a CDMA Carrier, Sprint or VZW, in your case VZW. APNs are set by the Sim from Verizon so you shouldn't be messing with those, nor should the option show up under mobile network settings.

It was like you. Sometimes network was OK, and sometimes, it was down...

So current working theory is that it was a software issue that cause the problem. I'm just unclear as to why it happened, and how to stop it from occurring again . I do have OpenDNS enabled on the phone, could that cause the problem?

Heres my problem, I'll drop out of an LTE zone, and 3G/HSPA will come on line. Only if its on 3G I never get any data, and sometimes with HSPA too. Not until LTE comes back on line again, but then if I'm trying to stream say music 3G/HSPA wont let LTE take over again for a pretty long while.

SAMSUNG CARRIER SMS/4G Issues

I recently got a new phone from AT&T. I haven't contacted them as I haven't felt it necessary yet. After recently switching from an iPhone 4, I love Android. I quickly rooted it with the Ping Pong method and installed apps such as Busy Box, Greenify, Nova Launcher, Clock Sync Adblock Plus, System Tuner, SD Maid, Titanium Backup, Uninstall, and etcetera. I listed almost all root applications due to it may being a problem with that. My phone worked fine for a while. I noticed it stopped working after some calls stopped coming through as well as texts. Randomly, I see that my texts don't go through, but after a quick restart it seems to work fine. I was wondering if there is any way of getting logs to help someone out there figure this out for me. If unrooting via SuperSU and then factory wiping my device would work please let me know. If there is any information I can provide you I will. The phone worked for the first week fine. Restarts seem to fix the issue until around ~6 hours of time using the device. It mainly sits next to me at my desk.
SMS doesn't go through or receive. Phone calls are not received (Have not tried outgoing). Cellular Data (4G/LTE) does not work.
--Edit:
I have frozen the OTA notifications from wsync. I also remove some bloatware thanks to System app remover (ROOT) by Jumobile. It gives you things that are not CRUCIAL to your system to remove. I removed a few things. Nothing relate to Samsung.

I'd make a backup backup of the phone using your favorite method (I seem to remember that titanium can do this), and try a factory reset to see if that fixes your problem. AoN

Well... Umm. dm-verify verifaction failed... So I'm guessing that I "bricked" my device. Guessing I have to plug it into my pc and do a flash somehow. Any info?
--Edit: Booted into my device with same settings. However I cannot do a factory restore as it always says dm-verify verification failed.

Beyond my knowledge. If the phone still functions, un freeze / restore all the system stuff you disabled, try again? But I'm just guessing. AoN

Use Odin to flash the factory OE2 firmware via PC.
If you're still having issues it may be a faulty SIM card.

Alright, I flashed everything. Re-rooted (I tested before root if the Cellular Data/Messages worked. Cellular data did not, but messages did (and haven't had issues after root). The cellular data still DOES NOT work. I live in a location where LTE is supported. Any info?

This may be s silly question but have you tried toggling the 2 switches under mobile networks/mobile data off then on? One of them is enhanced 4G LTE services. I read somewhere that this might help.

Call AT&T tech support and have them provision your data on the back end again. Just explain that everything works except your data. This can happen if there is a data block on your line or if someone used the my AT&T app to turn off data for lines on the account.
Are you able to make phone calls?
Do you see the 4G LTE logo at the top when wifi is turned off?

4G LTE logo does not display when wifi is off.
Phone calls work.

Data capability lost after signal loss

Every day I travel on the London Underground and obviously lose 4G signal when I am below ground.
Since the last update a week ago to 10.2.26.0, when I come back into a 4G area I cannot use any data services without either rebooting the phone or toggling Mobile data on and off, which is very frustrating.
The bars will show full 4G but no data will flow on any app until I do this.
Has anyone else experienced this?

Same on mine...

Yes same issue here

I had this happen to me earlier and it turned out that the access point settings had been altered at update from one firmware to the next. The system tries to install some generic APN-settings based on my operator’s name as my operator has no automatic way of installing them the usual way on this phone as it does on the more commonly used brands.
Check with your operator what the settings should look like and enter them under the access point settings for the sim-card if the current ones look off. Just an idea because I had the same problem going back to 4G from Wi-Fi. Reboot or airplane mode was the only thing to fix it for me. To be more exact it was the address for the setting “APN” that was wrong for me. The system had put an address that wasn´t a valid IP-address. Obviously, Xiaomi had tried to guess the address based on my operator name but got it wrong. As soon as I got the right setting in place all problems were gone.
This problem got worse as I had activated LTE voice calls. Before that it only happened occasionally, but with LTE-voice calls activated it happened every time I went from Wi-Fi to 4G.

When I ping that address it comes up as invalid. You should see if there are alternatives.

Doesn't seem to be the issue. I am on EE here in the UK and the APN is correct. Can't see how toggling data off and on would resolve this if the APN was wrong anyway?

I can see that but still, do a trace route for apn.fastweb.it and it can´t solve that address so there is something wrong with it. Anyway hope you will find the culprit of your problem!

I almost have the same problem .. after a phone call 4g disappears .. After the talk 4g comes back but the data connection does not work anymore .. Data off and switching on is the solution. I have send my phone back to the retailer i hope dee can fix the probleem.

I have the same issue.......latest Global Beta......switching data off and on for now....and hoping that fix is coming as it is annoying...

Okay so this is found to be experienced by others - how do we bring this to Xiaomi attention? Right now a phone that just randomly chooses to lose data capability is useless, as I lose notifications, messages, home automation activity prompts, Ring doorbell alerts, Nest smoke alarm alerts - pretty much renders the phone useless if I am not connected to WiFi, and the worst is not knowing it's stopped working till I try something.

One thing you could do if you have activated VoLTE is to deactivate VoLTE. If this makes a difference it sugests that something is wrong in your local configuration. Otherwise you may have to take it back to the seller.

Same problem here in Germany with o2.
I just found this solution to slightly another but very similar problem and I'm testing it right now.
Go to the APN settings (Settings -> SIM card Settings) and better do a reset to default (not necessary). Choose the o2 option and in a field called MVNO type select IMSI. You should be fine.
Will report back if this worked.

VoLTE is not enabled on my device, but this doesn't sound likely anyway - I have had the phone since the first week it was available in Europe - over 3 months - but the data stopping working only happened with a recent update. Anyway, this thread and other forums suggest this is a wider issue - can't see that sending it back to the retailer will achieve much as the replacement will likely do the same!

The APN settings are all greyed out on EE - I can read them but I can't edit them?

Any news here? I'm still stuck with this annoying problem.
I'm on MIUI 10.2. 9.0 Global and no updates available.

Just came here to say I have he same problem. Not really too annoying as all it takes is toggling airplane mode off then back on after a couple of seconds. But sometimes I don't even know the problem has surfaced and I end up missing notifications.
It happens sometimes even after I enter an elevator then leave.
