Xiaomi MI5S is dead after MIUI update?!

[tbmm]

Hi everyone,

After last MIUI update, my MI5S (Global) is not responsive anymore. I tried all the combinations of power and volume buttons, but the screen remains black.

The only answer I got is an error after running MiFlash :

So, summing up:

1) Doesn't startup on pressing power button.
2) Phone doesn't start in recovery mode.
3) Phone doesn't enter fastboot mode ( power + volume down).
4) No notification led showing battery charging status.


Best regards,
Tiago

Find any Linux PC, install adb on it and install recovery through fastboot mode ( Mi bunny on phone, fastboot command in console ).

Hi BlackJetCat,

The thing is, I cannot see any bunny on the phone because the screen is always black and besides that, I'm getting the message ""waiting for device" after executing "fastboot boot recovery.img".

I don't know if I'm doing something wrong.

Thanks for your help.

Wow, you don't see anything on screen? Try to press Vol- + Power for until you see FASTBOOT text and picture. If not helped, try to find any unbricking instruction for SD821. Also you can turn off and on battery [only by taking off back cover]. Maybe your problem related to screen or power controller.

Maybe you can try "deep flash", search on web about it, it needs a simple cable to flash. Search deep flash for mi5s.

I cannot see anything on the screen. I already searched for some unbricking solutions, but without success. I was able to flash the phone using Mi Flash, but nothing more. Mi Flash is the only place where the phone is detected.

I didn't try deep flash or removing the battery. Do you know if that would void the warranty?

Thanks for your help.

It doesn't need opening the phone, you just need to make a simple cable or buy it and flash device with Xiaomi Flash tool.
Here is a guide: https://forum.xda-developers.com/mi-5s/how-to/guide-flash-xiaomi-mi-5s-chinese-rom-to-t3530834
Update: I think it doesn't void warranty because its not kind of unlocking or opening the phone case.
