[How-To] THL T100s Boot problem !

[stefan66]

Hello, this is my first post and also my first major problem with an android phone. I have been searching high and low on the internet for over a month now for an answer to my problem but apparently no one out there have experienced something similar. So, my story: I bought this thl t100s in march and it run without a glitch until i decided to root and try new roms. Used vroot without problems and flashed a newer version from needrom. This is when it went pear-shaped. After reboot I lost signal, invalid IMEI and nvram error. So I restored IMEI and fixed nvram but I never been able to regain network. Phone just couldn't connect to network. Not even "emergency call only". Reverted to stock, flashed about every rom and firmware I could find, installed twrp recovery, used mobile uncle, mtk tools, sn_writter tool, maui meta, nothing helped. The phone is searching for network but is never able to connect. Also, I tested quite a few sim cards that are working in other phones. So I'm assuming it is not a rom issue, but goes deep inside the android system, like the system cannot connect to the phone radio. I have no idea what to do next or if there is anything that can be done. I would really appreciate your help, any ideas or suggestions.
Thank you
