No service on my MT4G. PLEASE HELP! - myTouch 4G Q&A, Help & Troubleshooting

My MT4G is having a problem getting service. I get no bars and it keeps saying no service. I tried rebooting and even putting a new rom on it but nothing changes. It still says no service. Nothing is wrong with my sim card because I tried using it with my old phone and it worked. So I know it has something to do with my MT4G. Please help. I don't know what to do.

Restore it to stock and return it for repair or replacement.

Is that the only option that I have?

Well you could flash some more ROMs to see if it'll work. It usually takes about 15 minutes [at the longest] for me for me to get service.

you should just get a whole new sim replacement first to try it out just in case

My problem: No phone service on P3600

Hi people,
My first post and unfortunately for a big problem...
I entered into a subway this morning and lost the sign (normal, of course) but now more than 10 hours later I still have no service, it shows the antenna and a ! next to it only.
I have tried the following:
- On commanager, The flight mode is NOT ON and the phone mode IS ON.
- Soft reset
- Hard Reset
- Tested the SIM card in a different cellphone, works OK.
- Tested a different SIM card into my P3600, no service.
It can't even find the a network when I set it to manual.
Please, any help can be useful...
thanks!
Claudio Henrique
try coming out of the subway
but seriously it sounds like it's knackered. Could try re-flashing the firmware.
another thought. Have you tried a sim card of a different mobile operator in the 3600 ?
Yes yes, lol, I forgot to tell that I came out of the subway...
Anyway, I think all I can do now is try reflashing. I have the original ROM 1.15.405.5...
I have just finished the reflashing and after all I still having the same problem... no phone service... My SIM card is working fine when I test it in my old motorola phone...
Anyone else have an idea??
thanks...

It really sounds like you've been methodical and covered all the possibilities. I hate to say it, but it may be time for the service center or retailer if they would take it back. The good thing is that you got your original ROM back on the thing so they can't complain about that. Good luck.
have you tried a different network operators sim card in the phone?
the phone's imei could have been barred from your current operator.
Yes, I have tried a SIM card from a different carrier, didn't work.
I'm sending it tomorrow to Teleservice in Germany (is it a good repair company?) to fix it up, let's see what happens.
Thanks guys!
good luck.
Hi guys, I'm back. I sent my P3600 for fixing and they replaced the mainboard and works fine.
But, when I lose the sign the phone just take forever to restablish it. Today I came out of the subway again and the phone din't get service and I had to soft reset it...
And thats what happened the day before I sent it to repair... I fell like it's going to happen again!
Try to take another road.

If i were you i'd start taking the bus!!!
Yes yes, your suggestion is valid... lol, but I'm serious, I don't know why I need to soft reset the device every time I lose service... that is annoying!
How many second a HTCP3600 need to find service when you turn it on or do a soft reset? I mean, what can be considered a normal behavior?
When I turn it on, it stays with the "!" for about 5 minutes and only after that time I get service... but sometimes I get no service at all....
I got in touch with Teleservice in germany, which replaced my mainboard, to see if they can give me some advice before I need to send it overseas, again, for repair... or replacement if possible!
If someone have an advice I would apreciate...
Thanks!

I always get a service within 5 seconds or something.. So there is definately something wrong with your device/simcard/provider.

Well you know what they say ,he laughs best who laughs last,anyway ,what you described happened to me as well ,yesterday i too was using the subway here in Athens and when i got home about five hours later i noticed that i had no phone service just an exclamation mark,i siftreset the device and the signal came back.

Help: No service.

I have a tmobile wing and I had it for awhile but just started using it again recently but when i put my sim card in the phone and turn it on it just keeps saying Searching...
I get service for like 2 minutes then it would just go away. This would happen when I leave the sim in the phone, it would get service once in awhile, like for 2mins every 2-3 hours, but never consistently.
My sim card works perfectly on other phones and when i insert a friends sim card into the wing it still has the same problem, it keeps saying Searching... I don't think its a problem with the sim card since it works fine with other phones.
I tried soft reseting it and hard reseting it but it still seemed to have the same problem. Does anyone have any idea what the problem could be or what I can do to try and fix it?
what radio rom does your phone have and what rom are you using?
you can check your radio rom by going to settings>system>about ( i believe). If not that, then settings>system> device info.
also, if you don't know what rom you're using, it's probably the stock rom.
It might also be that the particular spot you are in is just unlucky for reception and that other phones have better reception by design.

It says Radio version: 02.83.90
And i believe it is the stock rom since i never changed it or anything. and I doubt it is the area because I tried using it in several other towns.
anyone have any idea what could be wrong?
p4350
well on my p4350 over the past 2 weeks i have been receiving little signal like every 5 - 7 hours i mite get it for a bit but only for a sort time. i was wondering if it needs its radio updating?
any help?
Hi, I just want to share my story. maybe it could help you out.I had a wing for more than a year now. recently it had the same problem. it just don't have any signal at all, just keep searching. I tried what you did before. hardreset, softreset, and update the firmware. Nothing helps. since my phone is out of warranty, i can't send it to t-mobile. So i went to a local repair shop. They told me it could be hardware problem. I paid $50 to get it repair and no problem since. I don't know what they did, maybe replacing something inside. So don't just look at the software side, it could be hardware problem.
I have the exact same problem, and it's really pissing me off.

Can't get HTC HD2 working again!

Hi
Ok so my phone was working fine on a custom ROM when suddenly yesterday an exclamation appeared next to the phone signal and stopped from receiving/making calls and texts. I thought it had just crashed but after soft and hard resets and changing to a few others sims I just can't get my phone signal back.
Really strange as everything was working fine. I now have trouble flashing custom ROMs and am struggling to run a stock ROM because I'm on a mac.
It's driving me crazy as my phone is now useless.
Any ideas guys?
thanks
Quick update
I've managed to get the Leo Lite ROM running and everything is good except that damn exclamation mark next to the phone to phone, which means I can't get the phone working.
Anyone know know why this is???
Have you tried the sim in a different phone?
could just be a simple issue
And I know it a simple thing............but have you got flight mode on?

Thanks for the reply John.
Yeah currently having to use the sim in an ancient motorola and it works fine, tested with calls and texts. Also tried turning on and off flight mode but still that bloody exclamation mark stays.
That sounds like its been blocked. Theres a network there it just isn't letting it connect. Did you buy it second hand? or off ebay?

Hey Sam
Do you know what, I did buy it second hand, from a reputable store in town.
However this raises more questions than answers;
1. Why would it be blocked after several weeks of normal use.
2. Doesn't some sort of message need to be displayed stating the handset has been blocked.
Does anyone know if this is what happens when a HTC HD2 is blocked? i.e. the exclamation being shown all the time.
I presume a handset is blocked for security measures like theft. I will take it back to the shop tomorrow, they will have all the details of the person who sold it to them.
However is there no way this can happen from flashing custom ROMs? Even though that doesn't really make sense cause I had a ROM that was working fine and this happened when I was out and about.
It could be a bad rom, but it certainly wouldn't be in every rom.
I think id try going back to the stock rom, radio and spl (i.e an sd card flash, do you now if it has a provider locked rom?) and see if it is still there. If it still won't work, then it's definately either hardware or network.
The reason it could have taken weeks is, , seller trades in phone for cash, waits a little while, thinks 'i know'..., reports the phone lost/stolen to claim on insurance, insurance won't pay out without the imei being blocked.

Well I've tried flashing at least 6 custom ROMs, all show the exclamation mark.
The phone was sold to me as being unlocked to all networks, however I never tried with anything other than a o2 sim.
Now going back to the original ROM has its own problems. First off i'm quite new at this so sorry for sounding silly. How on earth do i go about finding out what the original stock rom, radio and spl is?
When I have these I can't easily go back as I don't have a pc, using a mac. I would have to use the sd card way but I can't find an official signed .nbh file.
I have a brand new T-Mo US HD2 with similar issue (out of the box). It's like the radio will not initialize. Did hard resets, tried to force it finding a carrier, etc, and it just will not turn on the radio.
I did find out that there is a likely issue with my SIM slot. If I attempt to remove my SIM card (which works fine in other phones) it is almost unremoveable and feels jammed in. However, once removed, I get connectivity via wifi and touch response is great.
If I insert a SIM card, it takes a LOT of pressure to reinsert it (yes, inserting it in the correct orientation), and the phone cannot connect turn on the phone's radio. Also, I get random phone.exe and credential.exe error message (plus the phone becomes very slow.
Don't know if you have any of these other symptoms, but the lack of connectivity sounds similar.
Supposed to get a replacement HD2 today, and we'll see.
I had the same problem too. I got unlocked code from tmoile and everything working fine for a month. It was working great after upgrade the latest rom 3.14 from tmobile download site (i got the message from them to upgrade), until i went out off country last month then the phone could not turn the phone's radio on. It kept at airplane mode. I been try to flash back and forth all the tmobile .50 stock rom and still having the problem.
Does any one know the issue to fix it? TIA
Looks like a hardware fault. You need to open case and check bottom two brass hinges are in working order and correctly hinged to make contact with antenna which is on the rear case at the bottom.
Follow the guide of opening s HD2 on YouTube there is a factory guide to dismantling the HD2.

Thanks for reply xlr8me. I just check the two brass hinges at the right side of usb connector. It looks fine to me. The other thing i didn't mention on the above post I was flash the dft_leo_nand android after tried all the stock rom from tmobile and the android said "no sim card", i also checked and cleaned the sim slot. Do you think any thing else to cause that problem?
One more thing without the sim or sd card the about phone show up all info of phone: imei, serial..... But with sim card in it just blank when i read the about phone hardware info. Thanks again
Did you try simcard from another carrier?

Yes I did tried the sim from the carrier of the asia country i was traveling to last month, that why i call tmobile to get the unlock code before i go. When i was there and inserted their carrier's sim and it won't work, even when i get back to U.S. I been tried either tmobile or at&t sim too. The phone radio won't turn on. The rest is working ok except those above error messages "A problem has occurred with device.exe" and "Credential.exe".
Do you think i can reflash with WWE rom .50 radio instead of tmobile's official rom?
Thanks
htcphonelover,
You will have to reset the phone back to default rom from htc website. You may also need to reformat sd card but the radio should still work regardless of whether the sd card is in or out.
My only concluding thoughts are that if the above fails to work then try a different sim card and still no good then probably something with the motherboard on HD2.
Good luck and update us with any new info..

Problem with the signal on HTC Magic

Hey there, i have a problem with my HTC Magic. I have had it in about 2 months, where it worked fine. Suddenly it couldn't get a signal to a network. When i try to connect to my network it says "Your sim-card dosen't allow a connection to this network" can anyone help me out with this? I've got HTC Sense on my mobile.
Same issue with stock Donut
I too experienced the same problem when traveling through Atlanta airport. This was a stock MyTouch Donut. After arriving at my next destination my phone worked once again.
I have initially rooted my phone today with Cyanogen latest. I am looking for the fastest ROM I can find without all the bells and whistles. After finding said such, I will be updating my radio.
I have had other strange issues with the radio on this phone. T-MO support suggested replacing the phone. However, I don't think the phone is the problem it's their lack of bug fixes.
I've got the same problem, 2 different sim cards on 2 different networks and both are showing no service and not finding any networks, but both are working in my old Nokia E65. Strangest thing, I checked my email over 3G earlier today, an hour later no service and has not changed since. Tried everything I can think of; nandroid restore, hard reset, safe mode, checked the testing menu. Only thing I haven't done is unroot and return to stock. It's funny, I always knew something would go wrong with this phone... Womans intuition maybe?
Willing to try anything that anyone has to suggest so I don't have to send it back to vodafone!
yea, i've tried everything too, at can't get it to work! - hope someone got a solution to this!

Well I called HTC and got the name of their authorised repairer in Australia (currently on an extended holiday visiting family here), so I unrooted and returned to stock but the issues haven't changed, so I guess we can nail down that it has nothing to do with the rom itself. The repairer did hint at a motherboard issue, but as I was playing the dumb blonde at the time I didn't push it too far until I send it off. It's just painful, I've searched and searched for a fix but most people seem to be able to find a network after a reboot or by simply waiting it out. 24 hours without my Magic being able to function in it's primary use, as a phone. This is very very poor.
I have had the exact same problem, so I unrooted and all. send it in for repairs. and all Vodacom(South Africa) told me was that they replaced the main board.luckly its covered by the warrenty. hope it helps..

Thank awesome to hear its a simple fix, but not so great that it's not a totally rare incident. I'm waiting til all the fuss of Easter is over to send my poor baby off to be fixed, but in the mean time I've bought a Hero so I'll never have to go back to my Nokia E65 again. I'm wondering, as there are other Magic owners with the same problem, is this an issue with just the Magic, or all HTC devices?
hey i still have the same prob with my 32b
i will do a radio update,
will see if it's fixed then,
if not i try to unroot
This has to be almost a year old lol.

[Q] Help!!! Radio Problems

Hi.
Yesterday when I woke up my phone couldn't pick up signal. I thought it was because of the heavy rain but now its still not picking up a signal. I flashed the stock rom and it could get signal some times but the problem is that it wont stay connected. Like when the phone goes into standby and you turn it on it loses connection again. I am now running the newest tabtastic chuckyrom. It only picks up signal outside but it loses it like every couple of minutes, and then takes a minute or two to connect again. Does anyone have any suggestions?
flash a radio?? 2.12 maybe? works great for me
Ok. Im gonna try that and tell you how it goes.
Ok. i have tried it and it still doesnt work. Im goin to flash the stock rom back.
edit: The flash rom is on and off with the connection.
I don't know if you're using one since you're on AT&T but the SIM card can affect that if it is old or getting worn out. Replacing it will help if that's the issue. Happened to me a couple weeks ago.
Ok. I went and got a new sim and its working ok inside but could be better. I just listed it on ebay and I will use my touch pro 2 until this sells and i get another one. But thanks for the help. Oh I also call HTC and they told me it would take a month to fix or send a replacement and that if the atennae failed that it isnt covered by the "Limited Warranty" so i would have to pay.
