NoGSM after phone drop

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,

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.

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.

I seem to have solved my missing SIM card problem. As many others have reported, the phone worked fine for at least a couple of hours and then it would just suddenly give this error.
I took my XDA EXEC apart and couldn't find anything really wrong, except the screw fixing the conducting tape over the SD rubber (top photo on page 17 in the service guide). This screw was a bit lose. I did also lift the metal lid over the baseband processor (MSM6250) for a quick peek but couldn't see anything obviously wrong. Then assembled everything again switched on to check that it's at least still working as before. That was a week ago and still no more SIM missing errors.

Htc wizard with wm6.1 won,t find sjgnal

i have a htc wizard with window mobile 6.1 and it won't find a signal it just says searching all the time. also the connection icon is on beside the signal icon but the connection icon has a "x" below it. PLEASE HELP! my sim card is fine it works in other phones. i don't know if it a software or a problem with the antenna .
ipl 2.26
spl 2.26
gsm 2.25.11
os 6.1.0.0

Help Please!!
I have read for hours hours on this forum and can't find a solution PLEASE HELP ME. I love my new wizard and want it to work right.

It sounds like you have an unlocked G3 (or else you wouldn't have WM6.1).
Before I flashed it, though, I would recommend just opening the battery, removing the back cover (it's not too hard), and checking the antenna connections to make sure they're still contacting the foil antenna on the inside of the back cover. Shut the phone completely off (press and hold power button). Open, and lift the foil carefully with a hobby knife and flatten it a bit, before laying it back down. Verify the two spring-loaded contacts are able to compress and extend fully without any coaxing from you. If they stick, flex them a few times to see if you can loosen them up. If they still stick, you could try using Isopropyl Alcohol to clean them, but you must wait until it is completely dry before reassembly. Reassemble and power up.
If it still doesn't pick up a signal, you might consider flashing GSM to either 2.19 or 2.69. Most Wizard owners end up on one or the other. A few find success with other versions, but they are exceptions.
Collection of Radios inside (ALL Radio ROMS) - xda-developers

I tried you solution but same problem . I've tried flashing a new radio but i have vista and the rom updater just crashes, i've read and tried a lot of the fixes the forum has told me to with no luck.

This may not be that helpful, but make sure that the SIM card is completely inserted. At first I didn't realize that it had to slide under the small metal things, so mine didn't work. =P

that was the first thing i tried. i even tried someone else sim cause i thoght it might of been my sim card nope not it.

I would recommend you flash the original ROM back into your phone and see if you get any signal that way.

Have you tried a hard reset? If your hardware checks out, then this might work. Also, did you or any previous owner ever have failed unlock attempts?

Dopod838pro NO GSM problem

i have my dopod 838 pro running on Schap's WM6 Pro 4.30 ROMs. it had been all right for pass 5 month since i upgrade the original WM5 to WM6. and since then i never flash it.
Yesterday afternoon, i can still use it to receive call. but at night. i found out that the phone doesn't have any signal on GSM network. when i double check it, it asking me to key in sim card password and said "unknown sim status"
if i key in the wrong password, it will state that my password is wrong. but if i key in the correct password, it still asking me for password. and stay on the same page no matter how many times i key in the password.
i already do hard reset. but the problem still exits. these were info when i start the phone.
M 05
S 04 NO GSM
B 06 D3.62
and these were info from bootloader
HERM 100
IPL-1.04
HERM100
SPL-2.10.Olipro
i very confuse with a lot of help over internet in thread for those no GSM problem. but i can't seems find any similar problem with mine.
WIFI and bluetooth were working fine. i can still goes into the Today screen and access every other things normally.
Please help me.

Do you know what Radio was on the device before the no GSM?

If you try to update your radio more than likely it won't update and freeze at a low percentage of completion. Sorry to say the radio on the motherboard is dead or dying. Happens frequently on the Hermes and the only way to fix it is to get a new motherboard. Happened on mine - would work fine then the GSM would start dropping out and reconnecting during the day. Upon reboot it would get the NO GSM message. Turn off leave battery out then try again - sometimes would start up then it would just die. After replacement of motherboard it just works.
No amount of flashing of ROMS including or not including the radio will fix it - the chipset in the HERMES is the weak link and they eventually just go. Either the solder has developed cracks from charging (heat) or flex.
Sorry.....

i not pretty sure . but it was original radio. i didn't flash radio before.
but i had downloaded the new version radio. successfully flashed it. but still no GSM.
STIM141: i think you are quire right. i had inquiries some shop of phone repair and have describe them my problem. since my phone die without me doing anythings to it. they pretty confirm it's the mother board die. they said the only way is to repair it and replace motherboard.

The best way to fix it cheaply is to find a donor phone thats confirmed working with a guarantee on eBay. Something that beat up, maybe the screen has problems and swap it out yourself. Its pretty easy to replace and you can do it in about 10 to 15 minutes tops. Need a couple of tools but they can be found locally. Should cost no more than about 30-35 dollars if you are patient. Next would be to scrap the phone for parts - but if the motherboard is bad you probably won't get very much unless you part it out and just wait for individual buyers.

[Q] Cant find any WiFi AP's

Hi all, I normally don't like to post questions because i feel like the answer is somewhere online, and i almost always find it. Apparently this is one of those times i can't. Bear with me as i wanna make sure i dont leave anything out.
My problem is simply that my HD2 will not find any access points when i turn on my wifi. This started happening to me with a previous HD2 i had about a month ago for no aparent reason. I had not changed or flashed anything on my phone around the time the problem happened. I figured i would ignore the problem because i had 3g anyways but then that HD2s touch screen failed so thats why i ended up sending it in for a warranty replacement.
Now i hoped that since i had a new HD2 that the problem would be gone, i mean how could it be possible that the problem would appear on a brand new phone. So i went about doing my usual. Installed 2.08.HSPL, followed by MAGLDR, followed by MIUIAndroid.com rom, same setup i had before the problem began. I made sure the first thing i did was turn on WiFi on first boot of the phone. To my suprise, No access points found. I know it is not my router as i have connected every other device im my house to my router, including other androids and windows phones. I thought maybe its a MAGLDR/Android issue. Flashed back to WinMobile 6.5 and still no acess points. Tried every radio available and still no access points.
Bottom line is im really confused how this can be with a brand new phone. Im pretty sure its a software issue but im out of ideas.
SO please if anyone can help. Please :'-(.

Just found out this morning that it can find my access point, but only if i literally lay it on top of my router. if i go more than maybe a foot away from it then nothing.

It sounds like a hardware issue. I read about these things having issues with a connection to the antennae that can be solved by taking apart the phone and cleaning some leads.

Sounds strange that such a new phone would have a hardware issue already. at this point though, im willing to try anything. how/where exactly would i clean/find these leads?

Check this: forum.xda-developers.com/showthread.php?t=834199 and this: forum.xda-developers.com/showthread.php?t=1190180, but be aware that opening your phone might void your waranty. Good luck

is that the only rom you have flashed? and was it nand, or sd etc...??
make sure because it could be a simple error in software as well..
something you can try and report back before opening up the phone

I first got the problem while it was still stock. then i flashed miuiandroid.com's rom with MAGLDR and still. then i went to tytungs ICS Beta4 roms and still. now im back to the miuiandroid rom. so it doesnt seem to be a rom issue.

also all the roms were nand

Hi my Friend,
your black Wifi Coaxial-Cable inside your HD2 is unpluged and not correct Connected. I had this three times at three different EU-HD2 Devices, too ( the Distance for a working WIFI Signal was 1 Feet. Normal, without Antenna ;-)). Regular the Connector at the PCM at the upper Corner fall of...
If you Still have Warrenty you have to bring this Phone to a Service. If not, you have to fix this little Problem by yourself ( you need 2 Minutes to do that ). Be Carefully when you Bring the whole HD2 inside your Backcover. You have to Tape the Vol-Rocker with a little Sticky-Tape. So this Plastic can´t fall off during the reassembling and is not to Deep to kill the Vol. Buttons...
The Opening is easy. You need only a Guitar-Plectron and t Torx-Screwdriver. Here you find Pictures:

Where the RED ARROW is, you see One Wifi-Connector and i bet a Sex-Pack good German Beer, this one is your Problem. Put this Connector Back and everything works fine...
Best Regards,
Micha
P.S. Sorry for my poor english !

Thanks so much to you and everyone who helped me out. Im going to see how much longer my warranty is because the only reason i would really send it back is if the touch screen fails AGAIN (happened twice already) but that wont happen for at least a year. So if warranty is gonna expire before then ill fix myself. again thank you to everyone.
