Thank you very much. It helped me a lot.

Hello, I'm having a problem with this phone. Leeco came to me today, but I'm not able to turn it on. When I tried turn the phone on, happend nothing, I had charged them and phone only vibrated after turn on. On screen showed battery sign (gray) and then went out again, sometimes the initial boot screen or recover screen appeared, but then it was off again. The charging indicator-yellow light, showed 50% battery on screen , I tried another charger - nothing. I Charged phone 2 days, still yellow light, phone doesn worm up, charger also doesnt.. I tried to flash STOCK rom, according to your instructions, but unfortunately since the display did not work, just black.There is small led subspice of screen. In the QFIL I get through the PC and the vibrations with the long push of the power button also remain-only when i charged phone.. I tryed Factory image "X526" and "s2_india_sparse_images". X526 image showed me some fail, indian version was ok. But situation is still as i described. Do not you know how to break it?

That was a very nice guide. I had trouble using the QFIL as it would spit a Sahara protocol error

After giving the phone a good charge and changing the configuration on the configuration menu, in the Firehose Common Settings, I set the Max payload size to target in byte to 49152 and it went allright.

Thanks a lot for your guide, it saved my dad's phone!

your post is very knowledgeable post.thank you for share this post.

Thanks for the tutorial. I have just 1 problem: when flashing twrp. Twrp gets stuck on the splash screen and after a while goes to normal boot. 'fastboot oem device-info' returns empty 'Device product name' where it should show [s2_india]. Any way to resolve this ? Also fingerprint reader isn't working.
