No GSM Error Tried Wiki already

Guys here is my situation. I have a Cingular 8525 for some time now I noticed that it was dropping signal and then recovering it I thought it was a radio problem but I changed numerous radios and it didn't fix the issue. Last night I noticed that it wasn't picking up any signal, on turning it on I noticed that I had No GSM I tried the way in the Wiki but I am unable to flash using the radio 1.16 to it I unchecked Allow USB connections but for some reason I cannot flash the radio. I started the phone attempted to flash the phone with several other radios and it just hangs. On rebooting I see NO GSM but when my phone starts up I see it reads the network but I cannot do anything else no calls nothing. Is there another way to flash the radio to my device or is the radio just dead? If so I have another 8525 thats not working can the radio part of it be changed?
Regards

It seems your phone is toggling between 3G and the older GPRS. By default, the 8525 automatically selects 3G if it is available. If you move out of 3G range (considering 3G support nationwide isn't great yet), which will happen often, you will lose signal temporarily and either switch to GPRS or regain a 3G signal. Currently I default my phone to use GPRS just because i can't be bothered with having to deal with dropping signal/calls as often as i used to with the automatic setting. There is a free tool called BandSwitch which can accomplish this for you. The newer version (2.1) is not free but if you can get your hand on the older version which is, it'll work satisfactorily well. I hope this solves your problem.

I had the same problem and nothing worked for me.
Try different solutions posted my various users and see if anytihng works for you.
I think it is a hardware radio problem and probably the only solution is to change the motherboard.
If it is still under warranty - get it done. If not, you are out of luck.

HTC MyTouch 3G - Cyanogen ROM no longer has data connection

I've unlocked a T-Mobile MyTouch 3G (32B) for AT&T. I rooted my phone yesterday purely out of spirit for experimentation. I've installed CyanogenMod-4.2.8.1, found on the website. I'm trying to connect to the market, but no type of data connection is being made.
The unusual part is that I have full signal strength. E or G sometimes pops on, but then drops off. I've quadruple-checked the APN settings, and they're fine. However, I did notice at one point the password had been deleted. I am aware that my phone version is not able to get on 3G band (although I'd like to find a hardware mod~)
I'm almost certain it's the Cyanogen ROM simply because before rooting, I had no data problems. Seems even a WiFi connection won't give me data. I've searched the internet to see if anyone else has had this problem, but it doesn't seem so. Any ideas?
Disabled WiFi and I have data. Apparently the two don't get along well. Just noticed an update to the ROM, so we shall see what will happen!
Or, if anyone has any suggestions on an alternative ROM, I'm not looking for anything too fancy (the MyTouch is serving as pure novelty at the moment; HTC Fuze is my primary phone). Speed and battery optimizations are most prefered, bluetooth/USB tethering a plus, and if it runs aHome or Home++ without a hitch, I'd be content.

I just upgraded to CM 4.2.9.1 on my MT3G 32B and am having data issues. Could it be a coincidence? Could it be T-Mobile upgrading to HPSA? Or could it be CM?

It's possible to be the ROM, as I'm on the AT&T network. I'll give the updated ROM a test as soon as I get some time to it.

Try reflashing radio. http://developer.htc.com/google-io-device.html

Works fine on my 32B Magic. Tried running fix_permissions, wiping and reflashing?

Got the same problem on my G1 with 4.2.9.1
When Wifi is active, after about 10 minutes i have no data connection anymore.
If i disable wifi i don't get this problem

i too have had this problem on my three magic 32a. i rebooted this morning and it went back to normal though. have only seen it once so i can't really comment on the cause. typically i have wifi always on and location by networks off...

How did you install CM?
Did you install the HTC 1.6 rooted base first, then the CM image after without re-booting?
You have to the first time you install CM. You don't say whether you did or didn't.

Did you remember to configure the APN correctly???

maybe related to instal issue?
I have the same issue but did "install the HTC 1.6 rooted base first, then the CM image after without re-booting". However upon booting into Cyanogen, I couldn't get past the "touch the android" screen and thus had to boot back into recovery mode and clear all data. After reboot I was able to pass the touch the android screen, but perhaps that wiped the 1.6 base settings?
Do I need to re-install, what if i have the same problem with getting past touching the android again?
I haven't tried updating the radio, but will try that first.

mobile network data
Found it: looks like toggle for mobile network data is turning it self off. Other than to conserve battery / airplane mode is there ever a reason to have it off? (is it bad to have on with WiFi?)
thanks.

new user in HTC HD2 and need help

hello,
Thanks for your best support, I bought a new T-mobile Htc HD2 and
i did unlock for it and working but there is problem many times it gives me
that there connection problem (DISMISS) and (SETTING) and i dont know
what can i do inspite that i recieve and send the calls normaly?
radio ver RADIO_2.10.50.26
the rom is the original with it and I want to use another rom
please tell me what can i do to solve this problem
and what is the best rom can i use (fast, beauty, save battery, good WiFi, etc...)
thanks again and sorry for annoying

ok
i personaly like HD2 2.0 UnOff Series
and with the connection problem hard reset should do the job. i had the same problem with the stock rom and i flashed it, so far its been working fine for a month

I get those errors now and again, but they dont seem to actually affect anything. I just have to close them.

I spoke with t-mobile and what happens is that it disconnects from data when it is idled for a while and it automatically reconnects when you need. I guess that is a way to save you money in case you don't have unlimited data i think...all you have to do is dimiss it...not a problem at all.

Data issues w/ CM6.1 RC2 + updated radio

Hey everyone. I've been having issues with my data connection and I'm trying to figure out what is causing it. I am using CM 6.1 RC2 and I have the updated radio from the vodafone rom.
For example, when I enter the market, about 50% of the time I get a network error after resuming from sleep and have to click retry once or twice before I can do anything. The data connection is just not reliable anymore (yet before this issue it always was).
I'm just wondering if there is an issue with RC2 of CM or if it is the radio update causing this. Can anyone comment?

I'm not sure this would be related, but after flashing 6.1.0 on my Dream I find it stuck in EDGE occasionally, usually when in the car or after, and in places where I get solid HSPA before 6.1.0. So far, I have to reboot to get HSPA (or 3G) back. There are some notes on updated radio and a kernel to address some radio problems, is anyone else seeing this?

Hi,
I have similar problem. My legend is not with the latest radio or kernel.
The specs are:
CyanogenMod Legend 6.1
Radio: 7.05.35.26
Kernel: 2.6.29.6
The problem that I see is: During the night when the phone is not used it looses the data connection. When I turn it on in the morning there are no mobile network indicators. I have to reset the network ( by airplane mode or reboot) ot get back my data connection.
During the day there are no problems.
I suspect that this happens because of the weak 3G signal in my area. However I use auto setting. ( 2G and 3G)
When I was with stock ROM I haven't such issues with dead data connection during long sleep.
EDIT: I have just upgraded the radio to 7.08.35.21. I will check how it works tonight.

I'm having similar trouble with CM 6.1 released just a few days ago...
I've posted this to Cyanogen Stable Forum for Legend:
h t t p ://forum.cyanogenmod.com/topic/11966-cyanogen-61-htc-legend-problems-with-3g-connection/
I think I've similar problem as you...

I have updated the radio to 7.08.35.21.
This morning when I woke up I saw no data connection again The signal strength indicator was full with bars!
Anyone has any clue?

I've been having some data issues too, I've had to go to and from Flight Mode in order to get any form of connection (data OR telephone) back, and I occasionally get stuck on GPRS. Toggling "use only 2G networks", waiting for the data to come back and then toggling it off again gets EDGE or H back, but it's pretty flaky compared to RC1 and the older radio.

I think i have the same or similar problem.
It looks like I have a data connection (3g is showing and signal strength is almost full). But when i try to connect to facebook, browser or somthing else what needs a connection it cant connect.
I have a taskkiller running when i kill all the task 90% of the time i will get a connection.
I have the same programs on my phone when i used 2.1 and with 2.1 I never had this problem.

Strangely enough it seems like mine is working much better lately. Maybe there was something up with Bell. I haven't gotten the connection error in days.

After update to radio 7.13.35.05 I haven't had this sissue again.
I will continue to watch he behavior.

[Q] HTC data connection freezing.

Hello all,
Not sure if anyone else is having this problem.
First of all, better to mention what my Aria is running on:
Stock ROM unrooted. Updated to Froyo from HTC via FOTA. I'm not located in the US therefore my phone isn't under AT&T which many here are. My ROM is strictly HTC's Asia's ROM.
Now I don't have much in a way of problems with my phone, its just odd to me that every once in a while (around once every week or so) I need to reboot my phone. This is because for some strange reason, my phone won't connect to the data network (3G) or it shows that it is connected but no data activity (even after I've instructed the phone to sync all information, i.e. weather, emails, etc). I've tried switching on/off the data network connection and also have tried switching between airplane modes on/off (in hopes to reset something) but nothing works.
I'm not sure if this is an inherent problem to the Aria's 2.2 update or if there is something wrong with my carrier, however the problem is ALWAYS FIXED right after a fresh reboot.
Anyone have any thoughts on this?

Phone information. Set preferred network.
Try switching between the different options.

Thanks for the hint thinkhope. I'll try your suggestion. May I ask what you think the problem may be?
Update: I tried it for a couple of days and I still get the same problem. I tried switching between preferred networks but the problem persists. Quick reboot and once again, fixed.

I also have this same problem, stock/custom ROM no matter which ROM the problem is still there, up to a point that made me wanna smash my phone on the ground. I tried to use my SIM card on my wife's SGS and seems like no such problems faced. Is this a common problem for HTC phones?
