[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...

Nevermind, my other problem was just resolved after reading a post in the cm6.1.1 thread. Settings-call settings-additional settings-my phone number.

[Q] S3 on Bell: not registered on network

hi everyone,
I got my S3 from Bell two weeks ago, it worked fine most of the time including calls, sms and data.
but occasionally for whatever reason the phone cannot make call or send sms, no ring for incoming call also. it shows "not registered on network" when I try to dial. at the time showing this error, there was signal on the bar.
maybe after long time, it can registered itself into network again, but most of the time, I just restart the phone and it works fine again.
I called Bell and they asked me to replace the SIM card, so I did, but I still see this error. So I think it is not SIM issue.
anyone has idea what the cause could be? or is there anyway to fix it?
I tried to search online before I ask, just couldn't find a solution so far.
so post here and hope anyone can help,
thanks for the help in advance.

I've had this issue as well.

I had this problems with rogers as well. Same as you I contacted rogers they told me to remove the sim and replace it. Worked for a while but kept happening. I got fed up and rooted then installed kyan rom and haven't had the problem since. Not sure if it was rom based or if the factory reset before flashing resolved the issue but haven't had it since. Hope someone figures this out though because it's annoying especially on a new phone that is stock.

I might try factory reset to see what happen.

Had this problem on bell a few times the first 2 weeks I had my phone. Went to the bell store and without hesitation they told me to change the mobile network mode from gsm/hspa+/lte
To just gsm/hspa+.
Reason given was the Lte network where I was using my phone (west island, montreal) wasn't strong enough. So my phone would switch between networks until eventually it got in that state. Personnaly I think the problem was more signal penetration into the computer lab I work in.
It's been 2 weeks stable so far. A co-worker reported the same problem to me last week and he took my advice and hasn't had the problem since.

Thank you very much for the tip. I was wondering that too, because I noticed that the network icon at top bar keep changing between H+ and LTE by itself. and I wonder why too.
I will try and see what happened.
thanks

SAMSUNG i747M not registered on network
I had this samsung s3 i747M from canada. Got it unlocked here in Pakistan. Placed a local sim in it. It recognizes the sim, registers it, makes calls, but then after a while, it shows "not registered on network". i restart, it registers network again, then loses it again. It keeps doing it. sometimes it is registered on network, but can't make or receive calls.
I have tried a number of things but the problem is not resolved and i'm fed up to the point that i want to throw this phone away.
The original rom had android 4.3
here's the list of things i have tried.
* changed the network mode to "GSM only" and "WCDMA/GSM (auto connect)" - NO USE
* Factory data reset a few times - NO USE
* tried a custom rom (it was so bad, i deleted it, don't even remember the name) - NO USE
* stock rom 4.4.2 from "sammobile.com" - NO USE
* tried flashing different modems from "http://forum.xda-developers.com/showthread.php?t=1831898" - NO USE
* tried changing the options from *#2263# to my network's specifications - NO USE
* tried sims from different networks - NO USE
PLEASE IF SOMEONE CAN HELP ME OUT HERE, I'M DESPERATE

@qamar_ish, what ROM is on your Samsung phone?

Originally it came with android 4.3. Currently it has this kitkat rom, which i downloaded from "sammobile.com".
the filename is this:
I747MVLUFNK2_I747MOYCFNK2_I747MVLUFNK2_HOME.tar.md5
It said on the webpage that it is the stock rom for SGH-i747M

Does your carrier require an AWS-compatible phone? Does the i747m support all frequencies provided by your provider?

I'm not sure about whether an AWS phone is required or not. But it certainly supports all the frequencies provided by the networks here. I checked it by using the code *#2263# and the options have the frequency supported by my networks here, that is "ufone" and "warid"
PS. I'm not an expert on this thing, whatever i'm doing, i learnt it during the last week..

It looks like your phone does support your carrier's frequencies.
Does your phone show the imei# from the dialpad? Is it possible there is something wrong with the phone's imei #?

It does show the correct imei when i dial *#06#. It had lost its imei initially when i got it unlocked, but got it fixed from someone.

Do you know why it lost the imei during the unlock process? Does the imei # in the phone match the imei # on the label under the battery?

I dont know how it lost imei. The guy who fixed it said that the imei is corrupted and he fixed it. Now it shows the same imei as on the back of the device.

I have never had a Samsung phone lose the imei if the phone was unlocked using a code, assuming that is how your phone was unlocked.
Did you try re-injecting the imei with the efs folder? It can be done using nvwriter.

Ok. I will try that. Can u guide me how to do it? Or share a link or something.
And thanx for helping me out here man..

R800at Help (Multiple Issues)

Hey Everyone,
I have been going through hell troubleshooting this fone for a week now. I would like to have this thread to keep a log of what has been going on. Any and all help is greatly appreciated.
Back story
Got phone from eBay. I know, I know. It is a prototype etched with "Not For Sale CB5XXXXXXX" on the front of the bezel (numbers hidden for privacy). The phone is in immaculate condition with a perfect screen and absolutely zero scratches. It appears to be used very little. It had a screen protector installed so perfectly that it wasn't even noticed by the seller. Also, it came with a white back cover but the bezel is blue. All these facts leave me with some questions.
The sticker under the battery reads:
Sony Ericsson
MoP 1251.18 11W19
Type: AAD - 388087 - BV AA CB5
Prototype not for sale S1 1251-5447.18
Not Type approved Prototype build: TP Blue AT&T
There are 2 bar codes and S/N and some other numbers and Made in China after that.
(If any of the above number should be kept private please let me know and I will remove them.)
More Back Story
Phone works 100% stock with my T-Mobile SIM card. I can get into fastboot fine. I can successfully flash superuser to get root on the stock ROM. I can then flash kernels too. I verified that it is unlocked with the Sony unlock code.
Here is where it gets good.
When I flash ROMS, all hell breaks loose. Gin2Jelly worked great! I had partitioned my SD card and loaded all my apps with Titanium Backup and was about to use it as a daily driver..... until I inserted the SIM. No service. SIM works fine in other phones.
Then I started trying other ROMS. The would flash okay. After booting and waiting the prescribed 10 mins as usual for all ROMs multiple issues arose. No icons, H/W buttons not functioning, etc.
This is where I am at. What could be going wrong?

Set your apn settings manually for tmobile.

Hmmm.... I forgot to mention one other issue. On Gin2Jelly, I tried that and was unable to set them at all. They wouldn't save. I was so frustrated. If I set the Name, APN, MMSC and backed out without saving the new APN would show up in the list. Once I set the MCC and MNC, and either saved or backed out, the new APN disappeared.
The SIM card simply would not be recognized. I even tried an app called Tweakker APN INTERNET MMS that is supposed to help with this glitch and no go.
Thanks for the reply. I wish it was that simple.

SUNDAY BUMP!
Bueler??
Just tried Turbo Gamer Edition. NO SERVICE!!!! I guess I'm not going to get this phone working. The ROM loads fully but I cant enter any APN settings. They won't save. Tweakker East Internet and MMS app not detecting SIM card either. This effin blows.

R800a_3.0.1.B.0.270_ATT.ftf is the only FTF that seems to work 100%. Is this the right version my my model?

Hi too have the same prototype model etching on the bottom below the key buttons withe same marking underneath the battery. I am running it on tmobile in the USA without issues. When I received this phone it was bootloader unlocked however mine was sim locked. Had to get in touch with alejandrissimo to get sim unlocked.

Question - Would your T-Mobile SIM work on the stock ROM? Mine seems to function fine once I enter the APK settings. I thought that if it is SIM Locked that I wouldn't be able to use my T-Mo SIM on stock ROM.

Ay one point I had the at&t firmware Nd it worked fine. However I am in nxt l.e. and it works great. And in my area I get hspa+ (5-7mbps down/ 1-3mbps up)
I had to look up the T-Mobile apn settings. Just install the app tweaker from the Google play store. Its automatic, make sure your on wifi. It will look up the correct apn settings for tmpbile USA or whatever/wherever and install. No issues after that.

My SIM won't work in other ROMs so it won't let me set APN settings. I've tried that app as well. The app only works if it can detect a SIM card. The phone won't even detect a SIM card unless I am on FTF R800a_3.0.1.B.0.270_ATT.ftf. This is my main issue. Does this mean I am SIM locked?

READ the OP please

So here is a run-down of what I just did.
1. Flashed R800a_3.0.1.B.0.270_ATT.ftf via Flashtool in Quickboot mode
2. Booted into stock ROM and inserted SIM card and was able to browse and make calls.
3. Entered bootable recovery wih Quckboot
4. Flashed Lupus 720p
5. Booted into stock ROM and was still able to call and browse
6. Made a NANDroid backup
7. Wiped Cache/Dalvik
8. Installed Gin2Jellybean 2.4.0 from Lupus CWM
9. Booted, waited 10, rebooted
10. SIM not detected. Unable to enter APN settings. Tweakker APN app says "Your SIM card cannot be used. Please make sure your SIM card is inserted and you are in an area with GSM signal and then restart the process..."
I don't understand how my SIM can work in OEM ROM but can't in all other ROMs.
Am I doing something wrong? Should I try another FTF?

Gotcha. My bad. I been troubleshooting this for like 2 weeks. Not really sure, LOL!
So,
I hooked up with Alejandrissimo who was able to properly unlock my phone. He said that it was unlocked previously with some copycat tool rather than the one he used. The copycat tools touch the hardware side of the device and the original tool doesn't. This prevented the usual method of unlocking and more steps were needed. This test involved the "Testpoint" method. This required me to remove the sticker under the battery and use a paper clip ( I also tried a small wire but the paper clip worked best) to short one contact to a ground spot for the battery while plugging the USB in and then clicking a button on the tool on my screen. All the while, Alejandrissimo was remoted into my PC and helping me along the way. This is almost necessary because both of your hands are tied up with the paper clip and USB plug. It was intense, LOL. Of course I donated to him for his time.
I am still testing. It seems to be randomly rebooting after R800a_4.0.2.A.0.79.ftf, / LuPuS_zeus_Stock-gB+iCsv5 / Gin2JellyBean v2.4.0.
UPDATE After flashing a stable firmware, LuPuS_zeus_GingerBreadv10-ram.img, and Gin2Jelly, sadly my SIM card is still not detected yet worked in the ROM on the phone after the process was done.

Any of those will work on your R800at , I flashed [.79] without problems. I have flashed them all in the past and I have used my device on T-Mobile and AT&T. Also don't worry about the whole R800a and R800at thing, they are basically the same phone, both capable of HSPA+ just released in different regions of the world. Which is why all of those firmwares will work on your phone. The [.270] is not the most current ATT firmware though, [.285] is.
Also you should note, that flashing a stock firmware is only for setting partition sizes and the baseband, after you flash a custom kernel and rom, most of the stock firmware you flashed in the FTF is gone. It is just good practice to flash a stock firmware and also gives you a clean install to easily troubleshoot from.
Per your OP though, I can tell you that booting up after flashing something and having no icons and hardware buttons not working is a wrong firmware problem, whether it be the FTF or the Rom you flashed.
I do know that every Gsm firmware has booted on my R800at without problems, which makes me wonder if some of your problems could be due to the fact your R800at was only a prototype and its hard to say what was modified for the actual release compared to yours and even compared to ozzmanj's

His prototype sounds like mine (see photos) I have flashed several ROMS before settling on NXT LE. And I had no issues with any of them. Again though I did have to hit up Alejandrissimo to sim unlock it as my bootloader was unlocked when I got it. Only difference was mine was the standard black and no AT&T branding.

*No signal strength after multiple flashes and recoveries

*No signal strength after multiple flashes and recoveries I have flashed multiple Touchwiz and Aosp Roms as well as restored the original stock firmware. (JediX20 and JediMaster + PacMan 4.2.2 and 4.3 + Stock Firmware Samsung 4.1.1 and 4.1.2 and even updated to 4.3 and downgraded back to 4.1.2) Nothing seems to work sometimes when I boot up ill have signal and my phone will work. Sometimes ill make a call while I have 3 signal bars or more and the phone will just be in dialing mode and after 10 seconds or so my signal will cut off and the call will disconnect saying there is no signal or "out of service area" and as soon as it hangs up my service bars reappear. And then there are times where the phone will show no signal strength at all for the whole time. In all instances data will still work. I have flashed and recovered through odin multiple times but I know the issue lies within the software I just dont know where. EFS maybe? I even thought it was in factory mode and downloaded titanium backup and deleted every "Factory Test Mode" I saw. Still no luck and im bout to the point im about to chunk it. Any ideas of why it is doing this? Any help would be much appreciated. A phone aint nothing if the basic functions of call text and web doesnt work.*I have also tried flashing K7 MA4 J2 and UCAMH3 Modems. None seem to help the problem.

Possible on the EFS...but that file is really an all or nothing deal...
It is possible to have a bad antenna or radio chip....but I do agree with you on a software fix first...to include a custom APN setup with experimented entries...
I've also heard that arbitrarily bouncing between 4.1 and 4.3 roms does alter the partition structure slightly ...but after looking into the EFS on both frameworks....I've noticed they have the same size and the information is identical...
I wish that I had more help for you....g

I even thought it was in factory mode and downloaded titanium backup and deleted every "Factory Test Mode" I saw. Still no luck and im bout to the point im about to chunk it. Any ideas of why it is doing this? Any help would be much appreciated. A phone aint nothing if the basic functions of call text and web doesnt work.*I have also tried flashing K7 MA4 J2 and UCAMH3 Modems. None seem to help the problem.

Are you really on straightalk like your profile says? Have you checked your APNs? You've been bouncing back and forth I'm wondering what's in there. Sounds like something in there is not happy.

My apns are fine and have always worked. The problem is not with that but rather signal strength, being able to make and receive calls. Messaging and data work fine.

My phone has always worked flawlessly until now. The signal can be normal but when I make a call it rings forever. .. the signal drops..my phone says it's out of service area and hangs up. .. and soon as it hangs up the signal bars reappear. .. in that specific order. It had never done that before until recently

If a radio/ril package doesn't repair the situation for you...and a complete return to stock fails also....(stock contains radio/ril )...
Then you should consider a hardware repair...
The note 2 had antenna issues on some devices...g

Greg,
Do you know where I can get details about the antenna issues. I searched several forums that pointed to the usb flex. I just replaced mine and still have the same problem of weak signal and constant signal drops.
Thxs

Thanks man ill try this out. Isnt there a way to just wipe the efs, system,data, dalvick, cache in TWRP and start fresh?

Do "NOT" wipe your EFS FOLDER...and do "NOT " re-partition your device in Odin either...
Simply use TWRP and wipe system ...data....dalvik...and cache...
Also ....you can wipe your internal storage as well if your important items are stored on the external SD....(photo's etc.)..
And as for the antenna question ...just Google it....g

I was poking around in my efs folder and went to Factory Apps and found a factory mode script. I opened it up in RB text editor and found that the script said on so I assume that it being on must have had something to do with the call feature. I changed the script from on to off and saved it. Soon after I tried making a bunch of calls its been working flawlessly but in exchange the lockscreen will not show up nor does the option to reboot/power off/airplaine mode shows up. Im going to Keep testing the calls in the meantime.

Im experiencing a problem nearly identical to yours. I have an i317 unlocked using a Tmobile SIM. Everything was working fine until I flashed a rom (I believe I accidentally flashed a rom with a Tmobile radio which boot looped the phone). After fixing the bootloop and flashing the cyanogen mod rom, I started experiencing the frequently dropped signal.
I have downgraded and gone back to stock several times which has not fixed the problem
After reading this thread I changed the factory mode script to off, but it doesn't seem to have affected the radio performance.
I remember reading that the partition could possibly be corrupted in a bad flash. What is the best way to reformat the partion?
Any help greatly appreciated

Did you reboot the phone afterwards?

Yea still no luck. But after about 3 days and a crapload of flashes I ended up flashing jedix20 and added the alexander theme..which suprised the hell out of me...the stock jedi had less signal bars like 1 or 2. I flashed alexander theme and my bars are from 2-4 with 4 being the best. Everything seems to be working. I had also did a test and made sure that my Network in setting was registered to the HOME network. That may have played a factor as to why the network wouldnt work even with signal bars. I flashed JediMasterX2 and ran across an issue like that. I flashed the att carrier files and it didnt work. Then I flashed the 7105 version and checked the Network operators and searched for a network. It pulled up AT&T and Verizon and when I chose AT&T and it registered my phone everything started working. I dont really like messing with the system files but I investigated the Jedimaster zip and looked under Jedi> carrier> att> and opened up the cscversion.txt under rb text editor and it showed an incorrect version. I317ATTAMA4....which im assuming was supposed to be I317ATTUCAMA4. Also under the SW Configuration. Xml the csc version was still the same. AMA4 it may be nothing but I would have thought it would have needed to match up. Ill have to look into it some more. I really want to update but hell idk. Might be done trying to flash roms on this device if everything works right

Would the phone having factory test and factory mode on the phone affect it any. I seem to have 2 factory mode apps with one being 560kb and the other 84kb. I don't know if those could affect the signal performance

Is your phone working now. Do you have details on what you did exactly. Thxs

Tbh. I honestly never got it to work right. I tried for months to get it to work right and to no avail. I ended up selling it and getting the note 3.

[Q] LTE Gone after CM11 Nightly Flash

First off, technically this is on a US Cellular hardware version but XDA doesn't have a forum for it. Hopefully this is the correct forum.
I flashed a CM11 nightly on 3/6/14 and it all but wrecked my LTE/4G connection. Worked great up until that flash.
I've done everything, as far as even bringing it back to my local USC store where they tried a new SIM and restoring back to their software image, *228, everything we could think of.
Nothing wants to bring the connection back.
There are more details here at the CM forum on this (Here)
I fear I may have to get a new phone to actually rectify this situation.
Anyone have any ideas?

I hear people lose lte/4g when they lose their IMEI or it gets corrupted after flash.... Look into that ...best advice I can give
