Tmo MDA radio sticks or resets

After I picked up the MDA I noticed that occasionally, while attempting an EDGE connection, the radio would appear to reset. Signal bars would disappear and the dots under the antenna would appear. The data connection would never take place and as far as I could tell the radio reset. This occurred several times in the course of a day. So did a hard reset on the phone which I hadn't done since picking it up. Now the symptom appears to have changed. Instead of it appearing to reset, it appears to "stick". Indicated signal strength never changes, the data connection is never actually made and eventually I turn the radio off and back on again via flight mode. Again, this only seems to happen while attempting a data connection, either EDGE or GPRS.
I've written Tmo support but I'm curious if this has happened to anyone else or if it may be a problem with my specific phone. And never having had a problem like this before, should I take the phone back to the store and ask for a replacement or do I need to hear that from Tmo?
Thanks!

I have a Cingular 8125 on TMO network and have the basically the same problem. GPRS/EDGE would occasionally stop working. Once it begins to "hang", I would notice the radio icon lose the bars and the dots would appear. However, It would reset on its own after a minute or two. This happens a number of times a day. Annoying the crap outta me.

The MDA ships with an older version of the radio rom. Maybe it would help if you updated it.

yeah, that's the one. I'll see what Tmo has to say, I'm sure as hell not flashing a phone that's days old and well within the warranty period. In the off chance it's software, I did another hard reset and prevented it from installing the extrom stuff.
update: Customer support asked me to try another SIM, which I did. When that didn't help, they told me to bring it back and they'd give me another one. Hopefully that'll be the end of it.

hi,
have the same problem. I just "loose" the signal and it searches, searches .... and again. SR or flight mode on/off usually helps. but its really getting annoying. I have feeling it is in places where there is a weak signal (but just opinio, not a proven fact). Sometimes happens, sometimes not at all. Dont know what to do about it.

I've noticed the same with the Cingular 8125 on Cingular's network. The radio version is 1.09.11. I am wondering if the later radio version would make a difference?

I upgraded the Radio rom on my 8125 to 1.13.10. I *think* it helped, but to be honest, it still happens. I also now, as a habit, turn off GPRS by pressing the red button for 5 seconds. This seems to help a bit too.
It's really a crapshoot. There are times when I can stay connected to GPRS for hours and hours, while other days i would get kicked within minutes. When the 2.8.7.102 rom is officially released, I will load that in hopes of fixing this problem.

I've had this same problem for months no matter device I use. At first I thought it was because I was using non T-mobile branded phones, but since using devices like the T809 as a modem and the MDA I get the same problem, edge/gprs would connect and stop working/hang after while. Most likely its a network issue, and this didn't start happening to me until T-mobile released edge data service. I'm actually a sales rep for tmo and haven't heard anything from tech support.

I've not had it happen with 1.12.10 (I think) - NOT the 1.13 version, but the one before it. Flashed it the other day - perfect since. The stock T-Mo radio ROM did it once in a while, usually in a poor signal area.

Old Problem
This happened on my Treo 600 on T-Mobile. The problem seems to be city-specific, so it happened in Pasadena frequently but not in DC.

hi, i just got the tmobile MDA and everything works perfect, i dont seem to have the problem of the GPRS, the only problem i have is that the sound of the phone is too low. any suggestions?
P.S. whats the website to download updates and softwares for it?
thanks

Yep, that was my experience exactly, I haven't had a problem even once since flashing 1.12. Thought about trying 1.13 but didn't want to push my luck. The phone seems to be 100% now.

constantly dropping service

I've had my wizard (cingular 8125) for just a little but over a year, but this past month I've had some abnormal issues with it.
I've dropped this phone a few times, but randomly this past month I have noticed a severe amount of service dropping in different forms.
Sometimes I'll be on the phone and it will randomly drop and start searching for a signal, in a well serviced area. Sometimes I'll be texting, and it will have service(2-6bars, enough for texting) but it will refuse to send the message, and when I try to call, it says invalid sim, and I have to reboot.
Sometimes If I am lucky, when the service drops it will pick it up within 20 seconds, it can take up to 5min, and sometimes I have to restart it.
This phone has been stock up untill this problem started (no rom flashing/anything) I tried unlocking it and trying different roms on it recently as a last ditch effort to fix this annoying problem. If anyone knows of a solution to this problem, I'd be really appreciative of it, otherwise im getting a new phone

While my first instinct is to convince you to sell me your otherwise functioning phone on the cheap, I must resort to being the good guy (or else get spanked by the mods...)
There is a registry fix for the kind of signal dropping you're describing. I'm surprised you went for so long without experiencing the problem. I did almost right away when I got mine last year. You should try it first, if you haven't already...
I think this is the one I used:
http://www.pocketpctweaks.com/pocketpc_tweaks/fix_drop_calls

i don't think its a Rom problem,as signal reception is not depended on the Rom,its an OS,rather its more depended on the Radio Rom (GSM) of the phone.Usually,by upgrading the Radio Rom improves the signal reception quality.Instead of flashing different roms,try to flash different Radio Roms and check if it improves the signal quality.
But,here,I think,perhaps,the problem lies more on the hardware part then the Radio Rom. as you say,it has been dropped a couple of times,it may be the the External Antenna cover has lost proper connection with the Internal antenna connection.Check the fastening clips which snap in to secure the External antenna cover to the internal are properly secured in and have not come off, are not loose or broken,which might be causing it to not having proper connection.
Cheers!

Well i tweaked those settings and tore this baby apart, and honestly the service was dramatically improved for this entire week, untill thursday, when service began dropping and it began to start telling me my sim was invalid. So I'm kinda lost here, it seems no one else has had this type of issue....
And on a sidenote I am unable to connect to gprs or edge to send pictures via mms. I noticed this after I started flashing different roms, so I think its software related. I did however download that .cab package floating around that has all the cingular media net settings. But when I try to send a picture my phone just seems kinda lost lol

bump!
I reflashed the rom to the official htc cingular rom, and that fixed the edge/gprs issue, but service is still bad.... Id like to try some different radio roms before totally giving up hope on this thing, but this site has seem to take down its ftp.... anyone have any wizard radio roms uploaded? preferably ones that work well with cingular/ at&t here in the US.... thanks

bump... guess no one has any ideas=(..... but since the ftp is back up ill try some radio roms

Sim/signal issues

My phone seems to be experiencing some random problems at the moment. It seems too have problems locating my carriers signal. My wife has the same carrier and her phone almost always has signal, even when directly next to mine.
Anyways, on top of that it seems that when I restart my phone, both soft reset and just turning it off and back on I seem to have full signal during the start up of the phone. Once the phone is fully started I will briefly have signal, then the phone will not recognize the sim. Once the sim is located I cannot get signal.
I feel this is some kind of software issue, as I very rarely get get signal, but in the middle of a call i will usually get the missing sim message.
Should I send this out to have it fixed or does anyone on here think they have a solution?
I have searched this forum as well as google looking for something similar but have not come up with any answers.
thanks in advance!

same problem with sim/signal
I have the same problem...i have been searching on the internet for weeks, yet I haven't found the solution. I have also sent it in to HTC and they returned it to me quickly saying there was no problem. I upgraded the ROM to WM 6.1, but that did not take care of the problem. Please let me know if you find a solution.

After much research, and trial and error with multiple settings/ideas I tried thinking outside the box. I had my sim replaced by T-mobile..... problem solved so far!
I should have tried this about 4 weeks ago. Hope this solves your problems.

Here I have a strange issue...
seems that every time it goes in stan-by, something happens to the radio module and it lost the signal... Only a SR solve it
This means SR each 2 minutes.
I flashed 3 different radios and few Roms (including the original shipped), different sim, but with no luck...
Need some suggestion

Replacing the SIM card works!!

Replacing the SIM card works!! Thanks.

Have the same issue, with a Touch ELFIN (XL). Ive reflashed it, but problem persists

same problem here with an elfin on onyx, tryied reflashing and doesnt work .
i made a call yesterday to movistar and they reset the "line" but doesnt work either.
maybe replacing sim will work?

hello!i have this problem to and i do not know what to do,i thoght that if i reflash the radio it will work maybe the 03.34.90 will work has anyone tried this?

Hermes freezing

Hi everybody!
First of all sorry if there's already a thread for this kind of freezing but i havent found answers.
My HERMES freezes completely, won't let me access screen, power button or any other function. It just gets stuck in what i was doing (mainly today screen).
Only way to make it work is to soft reset it. Is this a common problem?
Now as i write i realized the phone ain't working, now i recall i saw a blinking NOGSM when reseting!
I got this unit from a guy in the UK, it's weird because i remember it worked when i first tested it. Then i sold it to a guy and this guy claimed problems, could it be something to do with the sim card perhaps? Can it be a hardware problem?
Haven't got a clue. I appreciate your help!

I've seen people reporting similar problems when an old SIM card is used - so the owner might want to replace his old SIM with a new one, if that's the case.
Also, check if the SIM fits securely into its socket. I was having a problem with the radio suddenly turning off just yesterday, and it seems to be gone after I cleaned the SIM's contact pads and re-inserted it firmly.
Regardless, I suggest the "standard" troubleshooting be performed - that is, disabling automatic ActiveSync via the fake server trick, making sure today plugins are installed to the main storage (and not to the SD card), checking the registry for invalid entries etc.
Overall, most freezes are because of software, not hardware. Today plugins are known to cause freezes, as well as poorly cooked ROMs. If anything else fails and the freezes are not clearly related to GSM/SIM, try reflashing the phone with an official ROM image and run it for a week or so without installing any additional software. If the freezing persists, then it might really indicate a hardware issue

thanks a lot for your reply DmytroL, that was really helpful ill let you know if replacing sim works when i actually have another sim to test it!

Keeping my fingers crossed, as in my case, SODs (standby of death) disappeared exactly when I replaced my old SIM that dates back to 2001 with a way newer one. I've had only a single radio crash since then, which I'd attribute to the Phone Today plugin. At least, no radio crashes since I've disabled that plugin. The battery drain has also decreased significantly.
I really hope the old SIM was the root cause of all this nightmare. Time will tell...

Yes you are right I had the Standby of Death SOD this is when the phone fails to come out of standby with a power button press. This issue only affects some people on some networks. I'm not sure if its a network problem or a software problem but as only a minority of people have it, I suspect its mainly a network problem there is a software solution.
The solution is to change the phone settings band option from auto 3G/2G to either 3G Only (WCDMA + UTMS 2100 in Europe) or 2G Only (GSM) depending on your requirements.
Also read this thread http://forum.xda-developers.com/showthread.php?t=540943&highlight=standby&page=2 where the resolution was also to get a new SIM.
Obviously this only solves the problem when the crash is because of the sim and/or settings which impact the sim. To rule out a software cause its best to start with a hard reset.

The solution I found was removing the SIM card for it to work properly. I kept on reading and apparently the radio chip is sometimes badly designed (probably from a bad batch) and heats up more than it should causing it to fail. That is why it worked at the beginning and then froze after a couple of minutes. Solution to that was either paying twice of what the phone cost me to get a replacement board or actually earning money by selling the phone for spares!! For my shame in this forum i did the latter Anways hope the experience helps!

Maybe you could of just replaced the SIM itself with a new one, as sometimes that solves the SOD problem when adjusting the settings which impact the SIM ie setting 2G or 3G only from AUTO doesn't.

i´d tried it with 3 different sims and no change in the results!

I guess you didn't have the chance to set it to either 3G or 2G only from AUTO 3G/2G, on my network I have to do this to avoid SOD regardless of SIM. The default phone options result in SOD on a regular basis, now with 3G only (WCDMA + UMTS 2100) = Zero SOD and a totally stable phone.

HD2 Signal Problem

Ok my phone just recently started having signal issues no matter what rom i flash or where i am it will have signal for a little bit then it will say no signal. I cant figure out what the problem is. I googled it but most people have this problem with their phone brand new where as mine just started and i have had the phone for 6 months

most likely its your radio, radio is what determines your signal strength and quality, try using another radio version and see if that improves it.

thats what i thought it was to but i have tried all the radios and the problem just doesnt go away. I have tried soft resets hard resets but no luck im guessing the phones just messed up now though i have never even dropped the darn thing.

What rom, and other information are you using?

What about other factors? Like your environment. Did you recently get a new case or change anything physically about the phone? Maybe opened it up or something. Maybe your phone has a case of iPhone disease or something...just grasping at straws here.

Does it occur in the same location or every location? Does it seem like its attempting to "hunt" for a signal or do you just have something like 1 bar then it drops out and eventually comes back. Or does it drop out never to reappear only when you do a hard reset (turn off and on)?
I had a radio issue with my older TYTN (I) and it drops in a really strong area starts hunting then finds the signal and its very strong. Eventually it stops finding the signal unless you turn it on multiple times. Even this would not work and it wouldn't get the radio version when the phone was turned on. Had to replace the motherboard and it was fine since. Also trying to reflash a rom/radio with a bad radio in the phone can be pretty difficult - like it won't flash. Remember mine would freeze at 15% and never go any further.
If its the radio you probably wouldn't see the radio ver code when the phone first turns on. This is if the radio chip is really dying. Try the legimate original stock radio (use TMOBILE's ROM if you are in the US) for a while otherwise the phone should still be under warranty.

Well im using elegencia rom the newest one and i have tried all the radios and the problem doesnt seem to go away. The problem happens no matter where i am even in the towns were i would never lose reception i get no bars there once in awhile every 5 mins i get no bars then it comes back then it goes away. The phone is still under warranty im going to keep searching for another fix for the next week if not im going to send back i wish they would just give me a different phone.

if you have not done so try another sim card. when the sim card gets corrupted, they have a tendency to act just like you are describing.
