"no GSM" problem. All workaround posted doesn't work! Pls HELP!!! - 8525, TyTN, MDA Vario II, JasJam Software Upgradin

Hi all,
First of all I want to let you know that I did search the forum for a solution. In fact, I found a lot of workarounds but none of them actually worked.
Let me give some details about my problem: My Hermes was working fine. I was running the official WM6 ROM supplied by HTC, so no customized ROM here.
It was going fine until the WM frozed. Then I soft reset the device and after that I never got cellular signal again.
While booting the device I got the message: "no GSM".
First thing I tried was to flash a new radio ROM. In all the attempts the progress bar never moved from 0% and after a while I got the communication problem error.
Then I tried flashing a whole ROM. This time the progress bar stopped at 81%. Apparently in the first 81% it flashes the OS and in the last 19% it writes the radio. Anyway, I tried this a few times and never finished.
In fact, after every communication error message I got stuck in the bootloader screen.
The only thing that works is to flash a ROM WITHOUT the radio!!
Is there anything I can do to save my phone or am I condemned to use my Hermes as a phone-less pda?
I tried everything I found in the wiki/forums, but I couldn't find a working solution.
I suspect that the blocks of memory where the radio data reside got corrupted, could that be possible?
PLEASE HELP!
thanks in advance!
Chris

A similar thing happen to me several months ago. While on a call my phone froze and when I soft-reset it the dreaded 'No GSM' issue appeared. I tried flashing radios/full roms/etc, but nothing worked. I ended up sending my phone to the htc repair facility and they fixed it at no cost. (Other than not having a phone for ~10 days)

Thanks dang, but I don't have a HTC service center where I live (Argentina, LATAM)
I'm faithful that the people of this wonderful community will be able to help me.
Just for curiosity, where did you send your device? Is it in the US?
cheers

sounds like a hardware problem to me...

Hi, there! I found that a lot of us who have bricked our Hermes, don't have a responsive radio bootloader, so when they try to flash a full rom, the progress bar hangs to 13%, or 81%. This is because at that time the flasher is trying to enter the radio bootloader, but because it's corrupted, it hangs. Till today there is no known solution to this one. I'm far away from England where I bought my Hermes, so I'm not thinking to send it back for repair. I'm a programmer, so my knowledge may be usefull here. The first thing I must know is if i can use the "lnb" command without being SuperCID. I mean if there is something like a Hard-SPL with an "lnb" command - (or renamed for security reasons). Maybe there is hope!

---

How can I try that?

You can use 'lnb' in HardSPL without having a real SuperCID; however you will not be able to flash a radio with 'lnb' command. The radio chipset has its own bootloader, the and the SPL just acts as a pass-through sending the data directly to radio chipset through the s2410 UART.
I had one device with non-responsive htc_boot and tried all kinds of SPL patches to flash htc_boot again on radio, without success. The only known method to fix this is to take the BGA chip out with hot air and reflash it with special hardware, as it is not common to have this equipment at home, your only option is to send it somewhere to do it for you.
However, I don't want to discourage you to research on it, maybe you find something i didn't

I have a similar problem
I also have a NO GSM and corrupted CID but I can access KITL and use it with PB 5.0. and I followed this steps here but the phone doesnt boot completely. It stops just after the two boot screens on Black WM6 ending on a white screen and the debug window on PB after loading all sort of things begin showing these lines over and over:
@@@@@@ HUB state changes now @@@@@@
[HDC]HubStatusChangeThreadPN TRUE
[HDC]HubStatusChangeThreadPN FALSE
Is there any hope for me? I have the cingular 8525
thanks

Please advise.
thanks again

I sent it to the HTC service center in Texas, US.

I just got my replacement from ATT.. Had the same problem. Its a hardware problem.. I wouldnt waste anymore of your time.

---

first, i'm sorry for my english
I've the same problem with a V1605 (french SFR), i've tried every solution but flash radio doesn't work.
I can flash cooked os without any problem, but it's impossible to put official
It's only a pda now, it's better than a brick

---

My hernes use to be the same as you 'NoGSM'.I tried to install the official rom,but it 's not work at all.I called to service center ask this problem,so they said that it must be only changed the mainboard. That 's terrible!!!

No GSM but when sim inserted
Hi all, First sorry for my bad english.
I also have 2 bricked Tytn Hermes 200. Its not my personal ones Its my company's property, which pple were using this phones. So i'm facin with problem which many pple here having but with exception. both phones having no gsm error when sim inserted but without sim its fine. In other words , device info showing every info including IMEI when sim unavailable. And some times works with sim but after making few call and receiving phone hangs(not system) and goes off from network but anthena signal still showing few bars. I'm thinking maybe the radio hangs totally and goes off, and after soft restart NO GSM. I also tried many flashing upgrading those things nothing can really help me.
When im flashing original rom from HTC (the latest one HTC_TyTN_WWE_3.54.255.3_6275_1.48.00.10_108) its hanging on 12% and doing 3 or 4 times recovery , but its finishes succesfully. So what exactly happening in 12th%?. Maybe its started flashing radio and stopped on bad block ? But then why its finishes succesfully after few retry?. Ok so if any one wants to experiments on the phones except radio welcome. I'll help. And some can give me quick example of how to check bad blocks?.
Tnx.

@akarandomjames -
#1. have you try the comm button+reset button hold for 2-3 seconds
#2. OR try the comm button+OK button+reset button hold for 2-3 seconds
anyway, i'm not sure if KITL is dependend on the ROM version. because when my device was in NO GSM status, SPL is 1.04, HTC bootloader is 0108, and lost SuperCID. Because of my device is still has SPL 1.04, i was able to load WM5 full ROM upgrade using WWE HTC English QTEK_001 2.05.255.1 01/17/07 version (ROM available on this site under HERMES Upgrade link), run it twice. once you have successful load the WM5 ROM then try to do step #1 or #2 above to get KITL USB display on your screen device.
Note: i don't think KITL mode is not available once your device is in Production Mode. anyone here can verify this?

My device is still SuperCID and I know I don't have KITL...I have SPL 1.04 as well and HTC Bootloader is 0108. I can't install any ROMs with radios as they will hang at 11/12%. I will attempt this "overload" method where it seems some people have had luck with it...after a few recoveries it just finally installs...but I don't think that will be the case.
If I can't fix this in a few days, I will most likely use my warranty or just wait for the Kaiser.

My variation of No GSM
I feel like I have problem 1A...where I am able to boot into OS but no GSM.
I am still SuperCID, SPL 1.04, HTC Bootloader 0108. Last known radio before corruption was 1.48.00.00. ROM where this problem occured: VP3G 3.60.1.
I was not even in the middle of an upgrade...just a soft reset after my phone ALREADY lost GSM capabilities during a tether session. It was stuck with no signal in Phone Mode...I put it in Flight Mode...then tried to move it back to Phone Mode and it wouldn't do so. I soft reset...and the no GSM stuck.
I tried to reinstall radio...many errors...stuck on bootloader. At first, OS's only were not installing as well but I got past that. Now I am able to boot into OS's with limited capabilities...and they will NOT ACTIVESYNC at all. Regardless of how old or new the ROM is. I tried older OS's that I knew worked in the past for me...but they refused to activesync.
Due to that, I am not able to install latest HardSPL 2.10Oli via SSPL. That seems to be the only way to do it according to my knowledge and what I've read. Maybe mtty was capable but I'm not sure. HardSPL 1.40Oli wasn't giving me any problems though, but I just wanted to have the latest one so I can avoid IPL damage.
I can only install anything if I start the device in bootloader...and I'm only limited to the OS since my Radio Bootloader seems corrupted.
I'm not sure what caused the corruption in the first place...but I feel annoying now posting on different parts of the forum with a problem that seems to be growing in the community.
