[Sprint LG G2] LoveistheGroove:
Here is my OG post...please, anyone, help me to know what YOU would do in this case. I'm freaking out that I have a $500 paperweight I can't take back to Sprint because I'm rooted and on a custom ROM. AHHHHHHHHHHHHHHHH

Please help me, anyone. I am freaking. I flashed this ROM per the instructions (no I did not do a backup, my fault). However, although the ROM loaded, it told me I needed a T-Mobile SIM for WiFi calling to work. That may have been discussed before. That is irrelevant.

Since flashing this rom (Yes, I did the ROM, Modem, Reboot, and Firmware as said)...I can only make "Emergency Calls," I can't connect to data, can't connect to Sprint cell signal, and for the first time I can't get LG Flash Tool to work to get me back to Stock.

Can someone, anyone please tell me what to do? I need my phone soon because I'm leaving, but nothing works!!!!

Billy

Hi if you have LS980 you need to download room for LS980 here is the link: http://xdaforums.com/show....php?t=2754167

Than you need to boot into recovery twrp and than you need USB OTG Cable here is the link on ebay: http://www.ebay.com/itm/13cm-Micro-U...item35d4da865d

Copy LS980 room zip file to to flash drive connect to your phone thru recovery mount usb otg than flash ls980 zip

You will be back on Sprint and after that LG Flash tool will work to if you needed

Thanks again for your instructions and help. I got the OTG, followed your steps precisely, and it SAID it installed Stock ZVC successfully (twice, actually)...yet it still will only boot back into TWRP. In download mode, LG Flash tool still doesn't work. This computer has all drivers, Windows 7, and had no issues before this ROM.

Do you have any other ideas? Now I've bought a cable for no reason. Help, please!

EDIT: I used these instructions to get me out of the TWRP Bootloop:

Now I have the Stock Rooted ZVC Odex ROM installed, but STILL, no data, no signal connectivity. I try to update PRL and it says authentication error. I try to make a phone call and it says "Emergency Calls Only." This stuff ONLY happened after this (TMobile ROM). Please help me if you can. I've made major progress with your OTG instructions and getting out of the OTA TWRP Bootloop. Now how do I get past the "authentication" error and get the data and signal restored? Can Sprint do that from their side?

Edit # 2: I called Sprint, they walked me through fixing the MDN and MSID, factory reset, nothing works. It still shows "NO SERVICE," "AUTHENTICATION ERROR," AND ALTHOUGH IN MDN AND MSD my # is correct, in SETTINGS it shows my old (pre-port) phone number.

He told me to take it to a Sprint Store but clearly I can't because I'm rooted and on a debloated ROM. Please, any advice is so much appreciated.

Thank you,

BIlly
