I have a SGH-I747 AT&T version, I unlocked it using the built in menus. I upgraded rom on there from the stock to HyperDrive, I am on Tmobile network.
After upgrading, I noticed the MEID was all 0's so I followed a guide on how to restore it using NV-items_reader_writer.exe by generating using another tool and then writing the information from a text file to phone. After that, the MEID got repopulated but I am still having no network.
My phone was working perfectly fine till putting this rom in, I did backups with ROM Manager but then flashed TWRP recovery and can't access the nandroid backups from ROM Manager.
What can I do next to get my calls/texting working again?
Go back to cwm recovery...
Yep, I reverted to CWM and that led to other weird issues but atleast my network started working. What I did next was flash a stock rom using Odin and then flashing CM10.1 on there. Now everything is back to working!

I apologize if this has been answered before, but I have looked through the threads for 2 days and haven't found an answer.
I come from an Evo 4G and Evo LTE background.
I received my Note 2 on Friday. I rooted it and installed TWRP using the toolkit without a problem. Used Titanium Backup to confirm root. I booted into recovery and created a stock nandroid. All seemed great.
Then I downloaded the LJC to LK8 firmware upgrade zip and attempted to flash in recover. TWRP said everything went fine. However, I rebooted and was still on LJC. I then downloaded the Synergy (LJC) Rom since I was still on the LJC firmware. I confirmed the MD5 and attempted to flash through TWRP. Again TWRP showed that the rom successfully flashed, but when I rebooted, I was still on my stock rom, only this time I had to run through the setup again because I had wiped the system.
I reinstalled TWRP just to see if that would help, but nope, same problem.
Does anyone have any thoughts as to why zips aren't flashing through TWRP?
Thanks in advance.
So I have more than 6 hours straight trying to unlock this boy and It's giving me so many problems. I downgraded from JB to ICS 4.0.3 and flashed UVLE1 Radio. Did the 30seconds/1minute procedure couple of times and 'nothing'. To my surprise I go and check the Network Lock status (*#7465625#) And says everything is OFF. It 'should' be unlocked but It still asks me for a sim card. Any help on this?
Things I've done:
- Flashed many different radios
- Tried the EFC repairer from the PlayStore
- Tried to Unlock via the S2 SIM Unlock app from the PlayStore
- Tried different roms(Stock and modded ones)

Asking you for a tmobile sim? Did you try other sims. Att for example

Odin recovery
I had that issue when I first got my phone going from JB to ICS as well. I did an Oden Stock Recovery or Return to Stock.

Try using that, then going back to installing TWRP or CWM whatever you prefer, then go from there. That is what I had to do
Return to stock.
flashed recovery (TWRP or CMW)
Install latest radio if you want to go JB
reset
Full wipe
install Rom and Gapps
See if that works.
Hello guys I just wanna inform you that there is something happening with the CM 11 4.4+ based ROMS
they deleted my Baseband and IMEI
I restored through KIES and got my Baseband and IMEI back but this thing keeps happening and I cannot figure out why?
It's painful procedure because I did this more then 10 times
First I had to Reflash everything through KIES which makes my phone as DEFAULT
then I had to ROOT and install the ROOTED Original 4.3 then I had to install Clockwork Mod with MOBILE ODIN in order for me to install different ROMS
after that I do FULL WIPE ALWAYS
Cache / Dalvik / Data / System even Internal Storage
I installed CM11 whatever ROM u choose:
http://forum.xda-developers.com/showthread.php?t=2453586 (tried this one no success)

http://forum.xda-developers.com/showthread.php?t=2565259 again the same thing Bad baseband
Also this one:
http://forum.xda-developers.com/showthread.php?t=2493905 OMNI Rom (first installed older version everything was fine but when It updated to the latest OMNI I got the same Unknown Baseband and no DATA whatsoever)
so what the heck is going on? Please help me?
recovery might be the issue
I just had this problem yesterday. You wouldn't happen to be using TWRP recovery would you? I found that if I was using TWRP and Kit Kat AOKP I would have no service and my APN list would be empty. If I used Philz Custom recovery or CWM it would work fine.
I tried going downloading the newest 2.6.3.1 version of TWRP and it made my phone unable to boot. I had to flash another recovery via Odin in order to get back into my phone.
Just a thought.
I've had this issue as well and for some reason the latest nightlies don't play nice with my phone and recovery I'm using the latest official twrp for t0lte. Not t0ltetmo. I recently tried fishing the last multi window and I lost my microphone use. I have since reverted to a homemade build from January.. It seems to be the only thing that works.

Guys I used both CWM and TWRP both the latest versions... and this thing happen during both tries... I don't think it's the Recovery!
My LG G2 is on the latest version LS980ZVC rooted and latest TWRP Recovery(2.7.0.0). When I flash the latest CM11 nightly and GAPPS, Everything is successful. Problem is when I try to boot it, it won't go passed the LG Logo. I've tried factory reseting it through recovery while the rom is still flashed but to no luck.
I am not new to flashing as I've been doing it since the HTC Evo.
I've tried for the past couple of days searching through this site and the internet on my issue. When the ZVC update first came around there was a thread in the Sprint android development section that explained how flash any rom after the ZVC update and now I cannot find this thread.
Also, When I flash Mahdi Rom, it flash and boots perfectly fine. Only problem is, I get no data and service goes away completely and doesn't come back unless I reflash the rom. But it only lasts for about 5 minutes before it just drops again. When I switch back to stock and I find that I have to go into my mobile network settings and switch from global/wcdma back to lte/cdma in order to get service back.
Any help will be greatly appreciated.

Yeah I tried that as well and I would get 3G data but phone calls or texts didn't work either for me.
Zv8 modem
The CM11 nightlies aren't made to work with the new ZVC kernel and baseband. In order to flash CM11 from ZVC you need to obtain the ZV8 modem and flash BEFORE the ROM and GAPPS. Boot to recovery and wipe everything except internal storage 3x to make sure everything is wiped. Then flash the modem rom and gapps in that order exactly otherwise it won't work. After everything flashes clear the davlik cache and cache 3x then reboot to system. Been using this method since I got my phone and it works everytime with every ROM I've tried. Also for those interested in unlocking US GSM capabilities do this then install an app called Tellinfo, from there you can do everything to change over to your GSM bands and use a GSM SIM card. I've been on AT&T for 3 months now.
So my wifes i747 was running 4.0.4 so I decided to upgrade it for her a bit. Im not new to rooting and flashing roms so I figured why not just put a custom KK rom onto it in order to freshen it up a bit for her. I also have to add that it is a ATT S3 unlocked and being used on Tmobile network.
Came to the forums and downloaded SlimKat rom and installed CWM and flashed the new rom. Everything went fine, but in the end my wife didnt like the feel of it and just wanted a new phone. So I traded her my phone and got hers. Well i wasnt a huge fan of the SlimKat rom either, nothing particularly wrong I was just always a CyanogenMod fan. Im having issues right now because I cannot get it to flash any new ROMs without messing up. Ill either get an error in CWM saying it cant flash the new rom or it will Flash but then never leave the LOGO screen. Ive let it sit for 45mins before.
I was able to always restore to a backup and just keep using SlimKat, but just tonight Im no longer able to restore to the backup. CWM sits at "Restoring data... c7ac6bd9.0..." but never actually finishes the restore.
So am I bricked? or what should I try? and also can someone just tell me what Rom/Kernal/Modem I need to flash in order to get it working. Id really like to use the Cyanide L, with Shift kernal but im not sure which modem I need. Tmobile modem or Att modem and which number.
Any help would be great thanks.
Additional info: I wiped cache, dalvik, and system/data everytime I tried to flash new rom, I made a backup and saved to my external before the flash. It is carrier unlocked and rooted. model number is the i747. CWM is v6.0.1.2
Your CWM is outdated.
Flash the latest Philz tar.md5 file in Odin: https://goo.im/devs/philz_touch/CWM_Advanced_Edition/d2lte/
The latest KK ROMs will also need an updated bootloader and modem to function properly.
