Doesn't turn on after upgrading to hyperOS

[TamirG]

Hi guys,
I bought a new xiaomi phone yesterday.
I upgraded its firmware to hyperOS.
I used it for about 2 hours and left it charging overnight.
In the morning I realized that it turned off and now it won't turn on anymore.
What would you suggest to do? Do you think its a hardware issue?

If you are using stock HyperOS, you are reporting in the wrong place.

No, I used the following rom xiaomi.eu_multi_STAR_OS1.0.2.0.UKACNXM_os1-14

In this case you can try to turn on fastboot and re-flash the rom

Unfortunately, it doesn't respond at all. I tried to enter fastboot and also long press on the power button for 30 sec.

Hmm, it could be a hardware problem then.

Is it possible to speed up the draining of the battery so that I would try to charge it from 0? Or maybe it's not worth trying at all?

So, you unlocked the bootloader in 24 hours?

Check with the IMEI on the box and post the result hiding the IMEI.

So, a Cn version, the IMEI error came from your side since after the device was detected?

I'm not sure I understand your question
When I first put the IMEI code I got the model.
After that, I tried to put the serial number as well and I got the error:
"Your IMEI or S/N doesn't exist, please verify and enter again"

Ok, returned it under warranty.
