[Q] Why am I not getting signal at all...anywhere?

I just got a G2. perm rooted it. and everytime upon booting up it has signal for 1 second then literally just disappears and never comes back. can't choose mobile network or anything because it can't search for it. tried doing *#*#infor#*#* and it says GSM ONLY and everytime i try to change it to WCDMA PREFERRED it keeps reverting back as soon as i exit. the only way i've been able to get signal back so far is to connect to wifi and enable wifi calling, then after disconnecting i'm able to get signal and i'm able to check the WCDMA PREFERRED option but awhile ago i was on wifi calling then left my house and it was disconnected but wasn't able to get signal again.
can anyone help me with what i should do because although i might be able to get it back through wifi calling, this will be very problematic whenever i'm not near my normal wifi locations...
thanks for the help

Eh... I would try reinstalling a stock rooted rom.

Is it factory unlocked? Have you used an unlock code? Have you tried the full radio s off, super Cid thing?

I wonder if your SIM card is faulty, needs cleaning, or is just a bit loose in the socket.

This is what it sounds most like to me. Also try to install another rom since you have it rooted now and see if that fixes the issue. Make sure you do a Nandroid backup first though!

I never put an unlock code and I'm still on tmobile. I called them and so far I haven't had trouble with signal as much but my number doesn't show up under status in about phone settings...it just says unknown. Its only on this phone though, my n1 shows my number with this sim.

Just so we're clear.. Did this phone/sim combo work OK before your rooted the phone?

No it wasn't. For the past couple of days since calling tmobile, its been significantly better but today I did randomly have that same problem of no connection, but mostly right now my problem is my g2 not being able to read my phone number in "status" under "about phone" settings but it does on my n1. When I called tmobile they tried sending my number ota 3 times with no luck...

During the first 30 days you can go to a TMO store and get a new phone, pretty much "no questions asked". I'd go ahead and do that if I was you. Oh, go to a corporate store though, not a mall kiosk.
While you're there, get a new SIM, too. All free of charge.
If you still have the same problem after that, I'd try an exorcist

Is this problem solved now ? I got the same problem but have no chance to return it back.
If there is the way to solve it, could you please inform and share
Thx

My signal problems seemed to be resolved, at least for the past week. It was resolved by calling tmobile customer support and they did some tests. However, my phone not recognizing my phone number under settings> about phone> status, is still a problem. Even tried getting a new sim and still didn't solve the problem. Did numerous OTAs with tmobile that didn't work. My number still shows up on caller id and stuff its just that menu thing. Sounds insignificant but some apps use that to determine your phone number. Also, when putting my sim back into my nexus one, it does show my number...

[Q] Phone hangs after calls

My phone have been acting strange for awhile now. Sometimes after I end a call the phone seams to lock itself så I can't recive or make calls or sms.
It does'nt happen all the time and it started when my phone was completly stock aslo.
I've tried diffrent roms without any change. Did a factory reset today and did'nt install anything and it still happend.
Got a tip to try another SIM card but it seams my kids have lost it somewhere so I can't do that now.
Also had it sent to service and they changed the motherboard on the phone, so it should'nt be hardware related either.
Any other tips perhaps?

No ideas what this can be?
I have to restart my phone like 15-20 times a day because of this problem

I cannot understand what you mean by "lock itself", is your phone getting frozen? does it disconnect from network? does it just simply stay connected and do nothing when you dial/sms?
I think this info can help people directing you in the right direction...

When I end the call the phone icon stays in the notificationbar for like 15 seconds and after that I can't call or send sms.
Only way to get it working again is to reboot the phone.
I can still check e-mails and use browser when it happens, so it's only calls and sms that's not working.
Tried to format my memorycard today to see if it helps.
For some reason it seams to be working better when I'm at home and use WiFi.
Could it be that when I'm talking on the phone and it tries to sync something it happens? But when WiFi is on it works anyway? But it's a workphone so I don't use it much at home so that could be it too

If you are not using 3g/HSPA data and only using WiFi, it is worth putting your phone into 2g network only and see if that helps the issue.
You can do that in wireless and network setting, mobile network and chose GSM only.

Guess I could try that to. Question is what to do if it work.
Seams pointless to have a smartphone without 3g.
Or is there something more then the motherboard that could be changed perhaps?

If switching to 2g works, either it is a Radio problem/Network compatibility problem or hardware. I would suggest contacting HTC again and see they have an option to change something else.

Tried this week with mobile internet turned of and the phone worked like a charm then.
Think it could be the sim card that causes that?
Gonna try contacting htc again and see if there is anything else that could cause it.
Have been trying different radios aswell without luck.

Network Connection Issue - No 3g/4g

OK, I have been dealing with this since I bought my GSII and cannot find any information about it.
Firstly I want to say that I am completely stock and unrooted.
My phone does not like to keep a stable data connection. About 50% of the time, when I try to do anything that requires a data connection (facebook, browser, gmail, etc.) the 2 arrows under the 2g/3g/4g icon will stick being grey and my phone just sits there "loading". I tried a factory reset, didn't install any apps, and also got a new sim card and the issue remains. It happens everywhere so it is not just a bad network connection.
I decided to post the question here because yesterday I was playing with my brother's GSII, and his did the same thing.. So it made me think that maybe it wasn't just me. Has anyone else experienced this? Or does anyone know what might be the cause?
Edit: I set my phone to use 2g only, and the problem vanished.. So it doesn't like to connect to 3g/4g.

Try going to your mobile network connection settings, choose access point names, hit your menu button and click "restore defaults".. It may fix it, I had data issues and it did the job. Hope it works for you!

Do what the gut above me said. Also call Tmobile and tell them, they will refresh your data connection on their end. That will clear up three problems your having.
But if it's also happening to your brothers phone, it's a network error. Call Tmobile.

I restored the apn settings and had Tmobile refresh my data connection, and it still happens. I noticed today that it's not just data, I'm also unable to call or text when it happens.. Tmobile just said everything tested normal so there is nothing they can do.. And I really don't think it's the phone so I don't want to exchange for a refurbished unless I have to.
Sent from my SGH-T989 using xda premiu

Its happened to me before. For about a week, the data connection just dropped. It would come back for a bit and later vanish. I called t-mobile and they guided me through routine steps (i.e. taking the battery out, rebooting, resetting) but nothing seemed to work. They really couldn't figure it out and later told me to replace the SIM. I can't remember if they shipped me one or had to go to the store but either way that relieved the problem. This was on an HTC HD2.
That might not be the case with you though. At one point in time all the phones under my name lost data connectivity just as you explain. This really had no solution but to wait it out.

you mentioned your brother's is doing the same thing, its probably not the phone, but rather the cell tower your connected to is fuggin up. Try going 5 miles from where you currently are and see if its still happening.

Network error
Sent from my SGH-T989 using XDA App

Just in case it's not a cell tower or network problem . . . My SGS2, purchased in October, had the same symptoms as the OP. After trying everything the OP did, and more, I came to the conclusion that the firmware on the phone was corrupt. I used Odin to flash the factory stock ROM & Kernel images (2.3.5 at the time). There was a definite improvement in the faltering/hesitant/fail connectivity problem at that point, but it was still very subpar. So I then also flashed, again using Odin, the baseband ("modem") image - I did it twice for good measure. The problem was finally immediately solved at that point and I had very prompt loading of webpages, etc. Still working fine months later (and even better with a custom ROM). See the thread entitled "[Q]Is there a "true" factory restore for T-Mobile Galaxy S II?" for help about the seemingly same symptoms/problem you (and your brother) are experiencing. If your underlying problem is in fact the same as mine (and the poster of the thread I cited) then it's apparently either a bad factory flash or a post-factory corruption occurrence that is causing your problem . . . the coincidence of your brother also having the same problem aside. Good luck!

[Q] Phone wont start SIM

Hello everyone, this is my first post here, so be nice!
For starters, i have the European HTC One X. I've been having trouble rooting it, but I finally managed it! So, when it was rooted, I noticed that my phone didn't ask for my PIN code. I thought it had something to do with the SIM card not being correctly in place, but i checket it, and it was ok. I checked the Settings, and on Airplane mode, it says "turning off" without me turning it either on or off. I cant press anything there, and when i try to turn it off through holding down the power button, nothing is happening.
Its been a few hours, and I've tried to unroot, factory reset and other stuff. Tell me if you need more info, and I'll be thankful for all answers! I really need help here!

I think I have the same issue, could u check in setting about phone to see if your imei number and baseband is showing?.. mine shows as "unknown".. I have flashed multiple roms and run the ruu several times and I still have the same problem.

A Box should pop up,
Saying IMEI in the top grey box, whilst showing a long number in the middle white box.
If you have nothing in the middle, no long number - sorry to say, but it's 'bricked'
You won't get a working sim on a corrupt IMEI, and it seems you have deleted yours.
I assume your attempts to root as corrupted & broken your IMEI, I would never recommend one root click programs - always best to just use a custom Rom.

Well.. since its bricked.. If i use a fabric restore, would anybody be able to see that i had it rooted?
And btw, i thought if it was bricked, i couldn't do anything at all?
Because i can still connect to Wifi, and download apps and stuff

I believe your phone is bricked,
Unless you had a backup of your EFS folder which contains your IMEI, I don't think there is a way to restore it.
Because the IMEI is gone, no sim card will work, and you'll be limited to emergency calls only and wifi I think.
Maybe someone else can respond to verify this, but in my opinion - it doesn't look good for your phone (sorry to be the bearer of such bad news)
Hopefully someone will enter the thread to disagree with me, but that's just what I think.

Well, it is sad news indeed, but i really appreciate that you could give me the news. I have been googling like a maniac for a few days now, and noone could give me a clear answer. But do you think i will be able to return the phone if i turn it back to factory reset?

I've had this imei problem on my motorola defy (locked bootloader) and wasn't reading my sim after installing defy+ cm10 JB nightlies, but i recovered the phone to default using leaked radio flasher and it was fixed. Dunno if this could be fixed by an ruu flash but since its bricked what you got to lose ?

Hello again. I just found the receipt/bill (dunno in english) from when i bought the phone. There is a IMEI number there. Can i use it for something? For unbricking the phone, I mean.

Flashing the ruu doesn't fix the problem, I have done it many times and it still remains unknown. I believe the efs folder does not relate to HTC phones. It seems we are very much bricked! I tried sending it to HTC for warranty repair but because it has been unlocked they say the warranty is void..
Sent from my HTC Wildfire using xda app-developers app

Well f*ck. I bought insurance for it (when i bought it), and have reset to factory settings. Would anyone by ANY possibility be able to see that i messed with the software? And if they ask if i rooted it, or flashed ROMs, could i say "huh, what is that? How do i do it?"
I'm gonna try atleast. Update you later on the day

Yes I'm afraid.. they can tell the bootloader has been unlocked.. even if u re-lock it, it shows as re-locked....

Well, in that case.. I'll just deny it, and say i have no idea what a bootlocker, or loadbooter is..

It's best to:
Relock your bootloader
Flash the RUU that you need to get a fully stock device
And take it to the shop you bought it from, do not send it directly to HTC yourself - you want to always go through a middle man of possible.
.... And just hope.
Basically, as I first noticed - it looks like your rooting procedures have corrupted your IMEI leaving you with an unrecoverable device.
In the future, stay clear from one click root apps - best way to root has always been to flash a kernel or Rom that includes it.
Good luck and hope they ain't too fussy to give you a working device.

permanent airplane mode
I have a similar problem with my htc one x. yesterday I saw that it disconnected my SIM card so I rebooted my phome. After reboot it didnt find my SIM and stuck in permanent airplane mode (it shows like it turns off but it doesnt). I checked that my IMEI is unknown. Tried hard reset few times but it didnt work. My phone wasnt ROOTED or anything. Is there a way to deal with this problem without sending the phone to warranty?

[Q] Wifi stuck flicking on and off and hanging in no mands land

I have a Sasktell Note 2 and have major problems with the WiFi
When turning it on it will flick on and off then get stuck off, when i mean flick on and of it never fully turns on the on light comes on for maybe a split second then back of and just hands with it not being on or off and not usable.
I have flashed a multitude of roms and put stock rom back on but this problem will not go away and is random, sometimes removing the battery will help and it will work for a few hours or days then crap out again.
Tried and searched even did the copy the old etc/wifi setting over the orginal did not work.
getting close to the point of stamping on it and getting a Iphone:crying:
Thanks for any help

reboot your router...

Factory reset the device and set up WiFi again..
Sounds like a dirty device...
Router reset also as mentioned above...g

Thanks for advice not sure what you mean on router not using a router, im just trying to turn on the wifi on my phone and its not that it wont connect to anything it just wont turn on.
I have done factory resest 1,0000000000000 times and just flashed another 2 roms same problem.

If you are using wifi at your house etc..
Power down the router for your internet connection and reboot it..
This could also be a hardware issue...
It sounds like you have exhausted the other repair options with fresh installs and trouble shooting....g

Thanks no its nothing to do with a router its a phone issue.
Not connecting to router or anything for that matter just turning on wifi on the phone.
Pos is ready be thrown through a wall no one seems to know the reason
Also as wifi button is not working it also means hotspot is not working
Where can I get the original note 2 rom for sasktel every one I find is bell or ata one last ditch at fixing it

It now comes up with baseband unknown and the phone memory has dropped to 0 if i connect to the usb cable I can see the phone on the PC but has odd numbers when it comes to free memory and cannot create anything as says zero memory.
If i go to the phone there is no longer any signal and the memory is at 0 also.
I just re checked odin i think I clicked Nand erase all by mistake ooops

If you did erase the nand....the phone is effectively dead..
Unless you have a full backup to restore your EFS and IMEI #....then it's bye bye note2..
Oops is right....
Ya killed it....g
Edit:
Do you have a backup ??
That part about being careful was no joke....g

No back up so no phone.................
Could I not DL a nadro from online and flash it?
If that's not a option bye Note 2 I would like to say it had been a fun ride but you where a piece of crap and destroyed my trust in Android your brother SGS1 had a hand in destroying it also )

you cant download someone elses nandroid and use it..
sounds like operator error has runied another phone;
dont blame it on Android

I would agree operator ruined it im not blaming it very odd of you to read that from the sentence.
I stated my first android sgs1 no good nothing to do with anything other than the phone, inline mic and usb sound did not work GPS did not work Samsung stated no work around live with it. Note 2 over 6 months of no Wifi or hotspot makes phone useless for me as it is a required feature as country living no internet unless the phone works. Tried fixing and talking about it no joy so had already decided the phone was going in the trash, hence why im not that fussed that it bricked.

Very sorry about the phone...
