Bootloop Problem

[Shahar287]

Hi guys. I'm having a problem that happens all the time. I am on 4.4.4 stable ROM, using my phone regularly for a while, when suddenly it crashes, goes to black screen and shows the mi logo. It tries to launch the system and then goes blackscreen again, launching mi logo, and blackscreeb again with endless loop. I figured out the suloution: im launching recovery mode, switching to the second system (dual system), and when it shows the mi logo it's seems ok, no loop. Im entering recovery mode again and switch back to system 1 and then it launches successfully. It happens once in every 3 weeks or a month, and I'm using my solution. I had a miui 7 developers, when they decided to merge the systems. And when this bootloop happened again, i was stuck because the only solution was to seotch between systems and i couldn't. So I've changed back to 4.4.4 with the dual system. But i really want to install miui 8 and i know i could get that bootloop again.
Please anyone know what the hell is the problem and how can i fix this bootloop? Because i tried reset, format, flashing different roms and and version and this bootloop stays with me everytime.
Thanks for your time and patience.

Which TWRP?

How old is it, maybe battery starting to die?

 

[msdeepak]

trwp 3.0.0 as well as 3.0.2 , if battery starting to die it should not work for stock recovery and miui global rom as well, right. I am able to flash global rom using fastboot method and the rom is working fine, but not able to flash twrp

 

[Pertti Kosunen]

trwp 3.0.0 as well as 3.0.2

Where?

https://dl.twrp.me/cancro/twrp-3.0.2-0-cancro.img.html

Tried this?

fastboot flash recovery twrp-3.0.2-0-cancro.img
fastboot boot twrp-3.0.2-0-cancro.img

Boot straight to TWRP after flash.

 

[msdeepak]

yes. recovery gets flashed..black screen comes, when i touch the screen it vibrates as well.. but cant see anything

Might be some hardware issue. Battery can cause weird flashing problems, but then even global rom should not work anymore.

Have you checked MD5 of twrp.img to verify it's not corrupted?

i think i found the problem... some how my bootloader is locked.. night will try to unlock it and will try to flash twrp again
