---DONT MIND THIS, MY FAULT (Solved)---
With TWRP flashing:
* Whenever i try to flash it (i have the file in the adt bundle folder with the cmd window open from the directory) and write:
fastboot flash recovery [filename].img (yes, i've checked many times for typos)
I get this:
(Bootloader) variable not supported
---This is the actual problem---
With Stock flashing:
Then i tried to re-flash stock firmware in case that there were any corrupted file interrupting the process.
Flashed, but in the process, after, or while flashing system.img (All with RSD Lite), in the phone, appeared a red text line that said "sp space is not enough" and the phone took like half a minute to reboot again and everything seemed to be normal. But if i try to do any of those processes again, even if i re flash stock fw, it keeps the same.
Need responses please D:
