Self-Bricked Note 8 Pro, no access to it

[afresh]

Hello there,

Last Tuesday (January the 17th), my Note 8 Pro rebooted while I was typing on it, and since then, it just bootloops.

I see the "Redmi" logo for 5 secondes, then the screen goes dark, the smartphone vibrates and here we go again.

Even Fastboot mode is not working: I can get access to the mode, but it only last for about 10 seconds, then blackscreen, vibration, Redmi logo.

No matter what I do (even this tutorial to unlock the Booloader by MTKClient), the smartphone keeps rebooting.

I'm desperate, since this device holds too many unsaved memories and my 2FA authentication app...

I even tried to change the battery (I've read that a dead battery, with not enough power, could lead to such behavoir), but no luck...

Another fact: when I have the phone connected on my laptop, all of my USB devices are disconnected for 1-2 seconds at each reboot.

Any help is very welcome

Is it still possible to back up all your data at this point?

Have you tried adb pull your userdata partition?

They can’t boot….adb only works when booting or booted, and if it bootloops, they won’t have time to pull their data.

Bootloader locked or unlocked?

Even if you cannot boot into system, but if
- USB debugging is enabled, and operational;
- a cable works;
- you can boot into recovery.

Adb shall work in recovery.

Unfortunately, USB debugging was not enabled. I stopped developing for Android quite a while back now, and I don't turn on USB debugging anymore.

@Arealhooman My bootloader is locked... I tried unlocking it with MTKClient, but no success since the phone reboots during the process.

This helped a lot actually!

It seems that the power button got faulty and got constantly pressed, making the phone constantly hard-rebooting itself.

I have a piece of paper preventing the buttons from contacting the motherboard, and the phone stopped rebooting when charging!

Ingenious method. Glad you solved the issue.

I enabled USB debugging to be able to reboot into fastboot / bootloader without the buttons (since my piece or paper prevents all the button from working xD)

Only custom. Stock doesn’t support it.
