Hello,
I have a att 8525 which is all stock. When I upgraded to the att windows mobile 6 I started to see the "NO GSM" on the boot screen. It will come once in a while, the only way to get rid of it is by removing the battery. I have tried the wiki on how to fix the problem but it still comes up once in a while. Please I need help on how to fix this. Thank you Kass2112.
Anyone? please I need your help.
Wow. No one? please I need help!
If it is intermittent, it sounds like a hardware issue with the radio chip solder points losing their connection. You can try to refloat the solder with a heat gun. I think this thread has some info on it:

hi guys! I need your help.. my wizard keeps on booting up. What happened was, I tried to fix the stylus.. and the stylus problem has been resolved.. I noticed that the volume button becomes loose.. so I opened the wizard again.. I accidentally pulled the whole board and noticed that there is this orange flat wire-like thing.. so I placed it back. however looks like i did not successfully placed it back because when I tried to turn on the device.. it keeps on booting up with the T-mobile logo..
I removed the battery and placed the power cord and tried to turn on the device agian ad same problem happens...
is there like a way to diagnose or check on the circuitry ? is there like a link that you guys can provide me with..?
waaaah!!! i badly need help..
I was able to hard reset and set the device on bootloader..
thanks in advance..
Service manuals were/are available on the ftp, not sure how much help they will be to you though. I dont think they will help you much. I hope you get your device fixed.
the flat wire is the keyboard connection,
google 'wizard service manual' there are links on other forums and maybe here, it's too big to upload and i don't know how to zip it up at the moment, maybe i'll find out later
i see.. great!! I ll wait for your rply..
I badly need help..
thanks a lot..

My universal has had a tough life. I bought it on EBay with a cracked screen and a twisted neck. I have put a new screen and LCD cable into it and it works fine as a pda, but when you switch on the phone you get between 0 and 10 minutes of service before:
"The SIM card is missing"
pops up and all connectivity to the world (except wifi) drops out.
I have done a whole lot of googling and think I have one of two possible issues: 1. A hardware fault in the mainboard
or
2. A flashing issue.
In my attempts to solve this, I have flashed the radio ROM at least 10 times with many different versions. I have also reinstalled Buzz's 0.00 version and re-run the unlocker but still the problem persists.
If it is a hardware issue, the only solution I can think of is to bake the motherboard at ~190degrees to try and reset any weakened solder joints but this is obviously a bit drastic! Can anyone suggest any other software/firmware issues that I might try? I thought that perhaps something in the unlocking process had corrupted one of the deep down registers since although the device shows as SUPERCID, I cannot execute the d2s commands and get an error saying "not allow" from the bootloader.
Anyone got any ideas?
Thanks,
John
Fixed!
I followed the advice here:

and it now works great. Time for some serious hacking!

I recently dropped my 8525 hard enough to throw battery out of phone. I reinserted battery and started phone. Though I lucked out as everything seemed to work until I couldn't make a call. During boot I get "no GSM" instead of a battery version. I have done a hard reset, but it didn't help. I going to try to install a new ROM and if needed try to flash a new radio.
Anybody else have this problem? I am afraid it is a hardware malfunction in the radio.
If I cannot get this to work (I have already bought a new phone) I will be more then willing to donate (just pay for shipping) the phone to anyone who would like to work on it or test things on it. I have one half good battery and one good battery as well. Like I said everything seems to work but the actual phone. Let me know if you want it.
meh, that is not good news my friend, hope you get it fixed!
if it is a no go however, i wouldn't mind taking it off your hands
best of luck,
tbae2
Try to reflash original or stock rom. Go with the carrier rom you are supposed to have. It might work as there have been reports to indicate this.
Hope it works for you.
Cheers...
I have recently gone through similar problems, there are numerous things that can cause the NO GSM error on post. So here is the complete solution:
1. Some hard drops can jostle the antenna connection on the board, (a dodgy way of testing if this is the issue is to give the phone a shake and a few soft resets, the NO GSM error will sometimes disappear and state your radio version). There are numerous service manuals that describe how to disassemble and reassemble your handset (read the forums). It sounds scary at first, but so does not having a working phone (be sure you are out of warranty first). You will want to get some electronic circuit board cleaner and give the area around the golden clip on the top left (back facing up) a good spray (while you are at it, why not clean out some dust scroll button detritus). Then dry and reassemble, taking care to force the antenna all the way into the clip.
2. If step one really scares you or you are still in warranty, skip straight to here. A program called mtty (i use vers 1.42 , check the forums) can be used to interrogate the board logic from the bootloader, there are numerous tasks that can be used to clear registers and check gates for errors (for lack of a better word), the wiki has a great entry on all these.
3. A reflash of the radio and maybe even the os isn't a bad idea either... although remember that the latest radio may not be the best for your area/network (READ THE FORUM on this too)
Let us know how you go with it all, and good luck
if you need any further assistance PM me.

This was my idea last night as well. Froze on bootloader. I tried to also Install new radio but also a no-go. I am now downloading a new ROM without radio to see if I can get something other then bootloader. I will keep posted.
I can take the phone apart if I need to, I will make it a last resort. I am not afraid to though as I already have a new phone.
Seeing as I still cannot figure out how to make a ROM to contribute (vista and lack of programing skills) This would be a way I can assist If it would be more useful to someone here not dismantled I would like to look into it.
Update:
The radio hardware must be bad. I cannot flash a new radio or any rom with a radio. Schap's EM6 is working fine. I am going to look into discodergenson 's suggestion of taking the phone apart.
Schematic Diagram
Hi, I have a HTC 8525, with the same problem, doesnt start phone module.. anyway, in my phone, the sim card is not detected. Anybody have schematic diagram for this model? Or any other htc model, for reference.
I think this problem can be caused by dry solder in the driver of sim card, must identify it.
Thanks in advanced
(Sorry for my bad english)

I don't think a bad SIM card connection is a problem. Without a SIM card the phone still needs a radio connection to make 911 calls.
also obviously I only have a t8 and higher, not a t6 which is needed to take phone apart. I will update when I get phone apart.
Hi everyone,
I have a Imate Jasjam, which has served me well over the last few years. It was running Windows Mobile 5 with the Telstra upgrade that was sent out a while ago. A few days ago, however, I dropped it a short distance, and suddenly the phone function stopped working. Initially I wasn't even able to open up the phone application, but a few soft resets later, that now works. Unfortunately when I start it up, it says "No GSM". There is nothing written in the Device information about Radio version, Protocol Version of IMEI.
I did a hard reset - no joy.
I thought it might be to do with my rom version, so I installed HardSPL, flashed to Black Satin (as I'd always wanted to try that one), but still no luck. The same problems persist.
Does anyone have any ideas what I can do, or am I stuck with a PDA instead of a phone?
Thanks so much for your help!
Paul
My apologies for bumping my own message, but I wondered if anyone had any further suggestions. To clarify, I have tried the various wiki answers, but I'm assuming that because this was caused by trauma rather than flashing that it may well be a hardware issue. Is that a fair assessment?
Thanks again,
Paul
I think thats a fair assessment, its possible the radio may have popped out of its connection. Might be an idea to open up the hermes and check.
If flashing a stock ROM and radio doesn't fix it, then sorry to say but it's busted (unless you can fix the hardware part of it). Have an 8525 with the same problem.
Thank you for the responses. I'm game to have a play with the hardware, but wondered if there was a good guide to getting to know the inside of my phone anywhere. I'd appreciate it if someone could point me in the right direction!
Check mikechennon's guide he provided to deassemble the phones.
Hi all, I've been searching XDA-Dev for a while looking for someone with the same issue, and although I've found similar issues, nothing really helped much...
A few days back, my HTC Touch (ELF) started playing up a bit; the touch screen alignment was a fraction out, not too bad, just irritating. When I tried to re-align the screen (Start > Settings > Screen > Align), it showed the alignment screen with the + symbol. I went through the taps, and after the final tap it's supposed to go back to the 'Screen' settings window, but instead the re-alignment process starts all over again. It got stuck in an endless loop.
I thought a hard reset would fix it, so after backing up all my data I tried it. I still have the same issue, but now I can't get past the alignment screen during the initial device setup, so I can't use it at all..
Just to give a brief run-down, here is what I tried (in this order):
Re-align - No luck, got stuck in an endless loop.
Hard reset - still stuck at the alignment screen.
Re-flash Onyx 6 R10 ROM - same problem.
Try flash different ROM (Onyx 6 R11) - same problem.
Tried re-flashing HardSPL 2.28 - same problem.
Tried installing different version of HSPL (tried 2.26 and 3.10) - SPL doesn't change, problem persists.
I'm going mad trying to figure out what would cause this, I haven't dropped my phone or had it anywhere near liquid or large magnets, so I doubt it's a hardware problem. But at the same time; if it is a software issue, why doesn't re-flashing Onyx ROM fix the issue?
If somebody could help me with trying to get my HSPL replaced, that should either fix it or at least rule out one possible problem.
Anybody got some ideas...?

Its hardware - your digitiser needs replacing. You can run msp_remotealignment which may help push it through.
Better idea yet, use the search feature, there has been a few of these recently which have all teh information you would need.
For HSPL, look in the rom section and post in the right thread for help with that I guess.

Hmmm... I was really hoping that wasn't the case, I don't have money for repairs right now. But thanks for the insight.

As I said in my opening post, I did search and found quite a few similar issues, but nothing exactly the same as mine.

And yeah, I'll try there (again). Only reason I asked here was in case the problems were software related, and if so that was one part of my device that I couldn't change for some reason.
Well, since I can't seem to find any more helpful information, in the mean time I've ordered a new digitizer... Once it arrives, I'll replace that and see if that was the actual cause of my problems.
if you get stuck dissambling, theres the guide in the rom section I think - its very detailed and should help.
Sorry i couldn't be much use, Its hard to be when at work.

Thanks, I do remember seeing that guide a while back and (ironically) thinking to myself "I hope I never have any need to do that"... And don't worry, I know what you mean; I'm at work as well. I don't have internet at home unfortunately, so at work is the only place I can really get online.
For the sake of anybody else that has the same problem as what I described here: replacing the digitizer worked perfectly for me, I got my phone up and running again last night. This would've all been done a lot sooner, but I was struggling to find the right screw driver to dismantle it (requires a Torx T5)...
awesome, glad you got it all fixed now
