Hi,
I upgraded my MI4C to Android 7.
I started TWRP and then I selected install and selected the ZIP.
I saw that at the end there was an error in red (partition not found).
I did not delete any data, as I wanted to check - as suggested - if it is working like that.

But it does not. Handy is extremely slow. Also I do not see the Handy on my PC.
It is not recognized.
When I started to TWRP (reboot into recovery) the Handy just turned off.
Same happened when I used Volume up + power. Handy did not start. Just MI symbol
Then I tried factory reset from The menue. Handy just turned off.
Now what I see, TWRP not working, and also some issues with Android 7.

W hat can I do? I should first try to do factory reset. But how?

Hi I want to wipe now. But how?
MI4C is working ok now. I just had to wait 10 minutes more.

But when I try to start to TWRP as before, the phone shuts down. Seems to be as if there is no TWRP any more.
Someone else who has the same? How can I wipe the data now? I do not believe, that the non working TWRP is related to the locked bootloader.

Hello,
this is not the point. I would like to, but not possible.
I cannot start TWRP. Phone just shuts down. And only in TWRP I could do.

Maybe it is because of the locked bootloader? And therefore TWRP is not working? I forgot to wipe during installation.
Someone else who had the same problem?

and does TWRP also work again? Maybe related to the locked bootloader. Or is a manual installation of the new TWRP required, which is working together with Android 7?

thanks a lot. I have to wait. XIAOMI removed my unlock authorization from my account. Now the say "application rejected" and I cannot even apply again. As suggested I posted a request in the Forum of MIU to unlock BL again manually. I cannot understand why they removed. I still have the SMS from September 2016 where they confirmed that permission to unlock was granted for acount no xxxxxx.

I'll be honest with you! I could not careless about xiaomi s**t unlock policy! I just do it myself by downgrading my phone to 6.1.7 using edl emergency mode. f**k xiaomi and the unlock Bullshit!

It's draining fast because the first four cores are under heavy load(60 to 90%) all the time! A reboot don't solve the problem! Still heavy load on the first four cores without a ******* reason! And the last two cores are stopped all the time also!

Don't they test battery life? It's quite annoying flashing back and forth looking for the right ROM ...

I unlocked my bootloader after installing this ROM.

How? I unlocked 3 xiaomi devices. I flashed the xiaomi.eu rom. When trying unlock the bootloader with flash tool, I get the info that my account is different from the account info on my device.

I tried to login with phone number and email on both, Mi Unlock and Phone. But nothing helps.... :\

This happens because the information needs time to update in the xiaomi servers! It's not instant! So you will need to wait a couple of days before using the unlock tool!

andreivlad199 probably unlocked his bootloader after flashing the android n rom the same way i did, that is putting the phone in eld mode through fastboot and then you flash miui 6.1.7 to the phone using miflash version 2015.10.28.0 and to finish you give a command on fastboot to unlock the bootloader, then you just need to flash twrp and you are good to go!

I feel sad about this new Rom. It was highly anticipated, but it appears that it failed to meet the expectations. Maybe it will get better in a month or two.

I reflected overheating. Want to go back to my 6.12.22 but I'm locked, damn. is there any other way to unlock instead of waiting for xiaomi communications?
