Cycling Mi Logo At Boot, Can Not Enter Fastboot

[finek]

Hi.
I've bricked my MI2S after trying to restore lost lock screen password with the mi.com account, after a few unsuccessful login attempts it suddenly rebooted and after that it started cycling on "MI" logo (the screen goes on and off approx. every second).

If I hold the down volume key during the booting process it shows the fastboot logo and then the screen goes off and everything starts again...
I've also tried to short circuit the two pins over the sim holder with a ground connector, my computer recognises a qhsusb_dolad device, and then... you won't believe it... it disconnects and connects EVERY SECOND just as the screen would go on and off if I normally booted my bricked phone.

What do you guys think?
Is it unbrickable?

Any help would be appreciated. Thank you!

Maybe hold the power button until completely off and then try to access fastboot

Try this
Take the battery and insert it then charge your phone. Go on fastboot also if you don't see anything. Install MiAssistant and MiFlash and download a fastboot rom (there is a mirror on miui.it ). Connect the phone on pc and install the fastboot rom.

Did you try recovery?

Yes, of course, nothing changes.. i always get "MI logo" at any keys combination
I also tested key - this is not power key issue

Tell a friend to help you, one to press the enter key with the fastboot command pre typed and the other to make the rabbit appear... If u are quick enough maybe fastboot can stay if phone gets command.... I did this in a ****** chinese clone from a friend of mine and it worked... It was mtk based and not Qualcomm's but... Who knows, u dont lose anything for trying...

Had the same problem. Try holding down Vol down and Power button, when you see the fastboot screen (rabbit) release the power button, hold down the Vol down button for couple of seconds.

Yep I agree. Release the power button once you see the Mi logo.
