I've had my unlocked HTC Kaiser for 2 months now on the AT&T Network no problems. On Thanksgiving Day, my phone decided not to turn on after I left the phone to charge overnight. I figured it did not get a good charge so I tried recharging it. It was flashing red lights near the the top of the phone. So I go into AT&T on Friday to see if its the battery or the european charger that may be at fault. I played around a few combinations in the store and it suddenly/magically turned on. (I decided to buy the charger and extra battery anyways). The employee decides that for some reason or another, the phone needs a SIM Card. Well here is where everything went downhill.
After the new SIM card, I was unable to make or receive any calls, and no access to my data plan. Sometimes, I would have full signal bars but still was unable to make/receive phone calls. I've been able to make calls on very rare occasions; especially in this room in our school. What to give? So I went into another AT&T store and noticed that they had the incorrect IMEI number down in their system,. I asked for them to fix it but they said they couldn't change it for some reason and that the IMEI wouldn't be causing the problems I'm experiencing. So I finally called Customer Service Support on the phone and supposedly they were able to change it to the correct IMEI #. But still the same issues. I've done soft, hard, master resets, take out the battery + SIM card, you name it and still the same problem! When I took the SIM Card out of my phone and put it in a Blackberry, it did work! But when I took the Blackberry SIM Card into my phone, it did not. The support team told me that indicates that it is my phone; but I clearly told them that it could also be due to the fact that the towers just aren't recognizing my device no longer.
So I spoke to HTC about this and they said its the SIM card and they wanted me to go in and get another SIM card. So I went into AT&T today and got a new SIM card but same problem. Again, same issue. So I called AT&T Customer Support today and asked them to bump me up to Level II or III support. She says she cannot do that because my phone is unlocked (from HTC) and no support for that. I gave her the rundown on how my phone was working for 2 months until they put in the new SIM card and my cell phone activity clearly show that. Then she goes on to mention that other technical service reps that have helped me in the past few days clearly have pointed the culprit to be my device and not AT&T as they have exhausted all tests. And I told her, it's like taking a brand new car to a mechanic and then get the car back not running. If you ask the mechanic what did you do to my car, he's not going to admit to anything. She says that my device isn't being recognized by the towers. So then I brought up the point of "So is it my tower or is it really my phone?". I told her it's no problem getting a new phone but if I get a new phone, will it be unrecognized by the towers again. She said yes because it is unlocked. I said what about the thousands of other people who use unlocked Kaisers or any phone for that matter as they seem to have NO problems. They basically want you to buy the phone directly from them.
In all, I've spent nearly 10 hours on trying to get this thing to rework and be able to place/receive phone calls. Whether this is due to the events which ensued after the red light indicator on Thanksgiving Day OR the fact that AT&T switched my SIM Card and caused my device to be undetected by towers (whether it was due to the fact they put in the wrong IMEI in the first place or any adjustment they made to my account) remains to be determined.
The only options that remain is: 1) Go to TMobile and try out their SIM card on my phone and see if it works. I highly doubt they too will let me do that as they consider phone unlocked and don't want to help 2) Get a new phone through HTC and hope it'll work on AT&T again.
Any ideas or support??? heheh. your help is truly appreciated
I feel you pain Brother.......
I don't have a clue how IMEI and towers can just not register your device...though....but anyhow, did you check if you have the Phone in the Dialing screen-Menu-Options, then the tab BAND on the bottom and both of them selected as AUTO? if not, then try changing bands.......
If you know that then, I'm thinking only of AT&T could have blacklisted you or some sort.......but that is highly unlikely......
I had some problem like that when i'm out of the country using Foreign Chips, and it seems the Kaiser needs a bit of time to adjust to new sims, and that can take minutes, hours...or even days......who knows what is happening as the phone is "learning"....... hope this helped you a bit....
I've been using my Kaiser for several months now and I did not register my IMEI, I just popped the sim out of my 8525 and took off running. It sounds to me like your phone has failed in some way, especially if your new sim works fine in another phone. The question now really is, where can you get a Kaiser fixed in the US? I spoke with HTC on another subject and I get the feeling that it may be difficult. I got mine from a shop in Canada, guess I'd have to go thru them.
In any case, good luck, it will be interesting to see what it turns out to be.
I second RemE -- like him, I bought a Tytn II & plugged in the SIM from an older phone (in my case a Qtek 9100 not bought through AT&T/Cingular), and have had no problems.
i had a similar problem with my 8525. I bought a Tilt to replace it, and about a week later I gave the 8525 to my son to use. neither his SIM card or mine would work in the 8525, but they worked in other phones. I brought the phone to the AT&T store and the guy there did something on his computer, then the phone was able to work. I'm not saying that AT&T blacklisted it, because I don't really know. But it took a change by the AT&T rep at the store to get the phone working again.
I have been using Kaiser with ATT for three months now with no problem. I just used the sim card from my Blackberry and so far, no problems.
One month ago I bought an unlocked TyTN II to be used with my current number from AT&T.
The phone worked to an acceptable quasi-average performance in the US (NorthWest and NorthEast). Few days ago I traveled to Miami, Florida and the phone lost contact with the AT&T network.
Later I find your Forum where I could find a partial solution. After several trials and errors I installed the following HTC ROM version 3.28.405.0 WWE (Radio Version 1.66.17.56 and Protocol Version 25.83.40.02H)
This particular ROM worked in my phone because you can select the Network Band (the AT&T versions do not have this option): here I manually selected the band GSM avoiding the phone to automatically switch to 3G. For some reason any of all the ROM versions in this phone loss the Network connection when it goes to 3G . Only the ROM versions from HTC has a software piece that allows forcing the manual selection of the GSM band.
Of course, this is not “the solution” because I would like to use this phone with 3G and more.
Anyone has had this problem and found any solution?
There is a well-known problem of early Kaisers having a hardware defect and the 3G radio dying. Mine was included in the lot. Return to service was required and the mainboard had to be exchanged under warranty if still valid, which was usually the case as it happened relatively early in the product's life. Reports of it are getting rare now as most of the faulty ones have been fixed, and newer ones were corrected.
I don't have the link to the thread collecting most of us doomed users anymore, but could try digging it. Search might help you.
The common fault was that in 3G mode the device would show network bars, but would not be reachable when called, and when trying to call it would just drop.
HTC-US Resolved my Problem
I owned this information to this forum:
After many workarounds and trials/errors, I called to HTC-US explaining my problem with my TyTN II.
They worked in following way:
1. I sent them, to my cost, the phone (they asked to send only the phone without battery, back cover and SIM)
2. They took in deposit the information of my credit card just in case they needed to use it for a payment if the repair is out of the warranty. If this were the case they would inform me the amount and I had to decide to make the repair and pay the charge or not to make it.
They told me that they had to change the phone main board: I believe that everyone who has a similar problem like mine (bad or not connection to the 3G network and sluggish touch screen) should contact HTC-US to Customer Care Department, 1-888-617-1113, M-F 9AM - 6PM EST.
In my case the phone was in warranty (although I flashed the Hard SPL in the phone, but the hardware was untouched). Therefore, I had to pay…zero. And they returned my phone in just 4 business days.
My phone is working very good, always connected showing an H indicating the use of a HSDPA network.
The cost of the solution was $ 20 by the FedEx service to send them the phone. Good deal.
recently bought a htc diamond from a market stall which i think was a mistake!!! he said it was all working and put my sim card in at the stall which the phone turned on and everthing seemed to work, on closer inspection i have no signal the internet works i take it the gprs is still running through my sim but i dont recieve calls / make them or texts due to the fact i have no signal!! ive tried updating the rom with the one from orange website that works but still have no signal, now i like the phone so was wondering if there is a rom / hacked software for the phone that unblocks it? i dont mind having h#dodgy software on it as my contract runs out soon and will be getting a new phone anyway just need this one to work for the time beeing!!
Not too sure, there is a few things that could be wrong.
Broken antenna?
Software problem?
Blocked IMEI?
just checked the imei number currently unblocked so its not that!!
try another simcard older sims are not always compatible
but most places operators send you a new one for free if you "lost" it or broke it
Didn't you try to make a call before paying for it? I hope you didn't pay too much!
From what I read in the first post, it seems as tho you say the internet works?!? Do you mean cellular or Wifi Inet? If you have cellular Inet then you have a signal! Cellular Data cannot be transmitted if there is no signal.
Take a look at the antennae: There are two "sticker" antennas {1 above & 1 below the battery} Remove battery cover. At the top of the device is a sticker antenna that is for the Wifi & Bluetooth. At the bottom is a sticker antenna for the cellular radio. If the sticker looks damaged then that is your problem. Also check to see that the Void sickers are still there {there should be two; 1 above & 1 below battery}. If not then someone has opened it & possibly damaged the antenna. Don't forget to look at the LDI {Liquid Damage Indicator} located under the lanyard hook while you're at it.
You can also try flashing with a different Radio. Read the Diamond Radio thread in Diam ROM Dev.
first of all thanks for sharing such useful tut....though it didn't work for me cause I can't enter DIAG mode.
second of all I'm having a little bit of different issue with my Rooted HTC one M7.
My phone recognizes WCDMA signal absolutely fine( 3G data connection is flawless) but it won't detect/recognize GSM signal no matter how many different cell towers I go to. when I switch to "WCDMA" or "GSM/WCDMA auto" mode it receives good signal, but when I switch to "GSM" only mode then it turns out to be "emergency calls only" thing(I tried this with 10 different vendor SIM cards). To make sure my SIM hasn't got any issue I tried it in different phone which did good. I can't say that if it has Hardware issues, but to clear my doubt I went to Authorized HTC service center. The front desk engineer guy took my phone to the technician and came back in a minute and told me that motherboard needs to be replaced (can they really diagnose phone's H/W in a minute?? also my phone's rooted and 18months old so no warranty). That MB thing costs around 80% of mobile's current market price so I came back with faulty HTC one m7 in my pocket. And here I am... I thought I would ask some experts in this community to give it a try on software side otherwise the phone is already 90% useless as there no coverage to WCDMA in my house.
Now you may be thinking that it is Service Provider's coverage issue, but hey I tried using my SIM into two other phones at the same place. Out of which one was "Nokia Lumia 820" and the other one was 6 year old "Nokia 1110"(though it doesn't support micro SIM, I inserted it carefully to make proper copper contacts) and my SIM worked fine with GSM signal in both the phones, as of course 1110 works only with GSM.
I can't believe I'm having this weird issue and now I can't rely on HTC's service centers. So any help is gonna be really useful.
I appreciate your time to read this and thanks in advance.
Have good time ahead.

Yes, yes I did try that.
With losing all the hope in my phone, finally today I handed over my phone to a local technician for looking over Hardware side issues.
@zelendel, thank you for your kind suggestion and I appreciate your concern in this matter.

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.
