If i understand well, if you can get to twrp there is no reason to worry...
You just download an official / developer rom or any custom rom, reflash and you are done.
Yeah I know, thing is, mi4i doesn't have an external memory slot..

go to recovery and connect your phone in mtp mode from recovery , take backup from internal memory and flash official stable rom
You may flash the device recovery/kernel/firmware via FastBoot
Flash TWRP Recovery via Fastboot, then adb sideload a ROM on the Device. Or Download Official Fastboot firmware for the device and flash it.
Don't forget to say thanks
flash the device with fastboot rom via FastBoot using mi flash
I have the same problem. Just Go into TWRP and wipe Dalvik/Cache/Data/System, after that just flash ROM again and everything works fine
The problem is with firmware and kernel. The firmware isn't compatible with kernel. If u flash the whole rom with firmware it will be fine, if U know witch FW have u used flash it flash it back or flash back original kernel.

Whatever You Do, first take a backup of your EFS Partition with TWRP or MI Toolkit. My device crashed and corrupted all partitions suddenly and my IMEI is lost now and I didn't have any backup of EFS to restore my IMEI.
And for restoring your device back to normal you will have to follow this..
1. Take backup of EFS and store it somewhere safe in you pc.
2. Download and extract the Fastboot ROM for Mi4i from here : http://update.miui.com/updates/v1/fullromdownload.php?d=ferrari_global&b=X&r=global&n=
3. As you have already rooted, I suppose that you already have adb drivers installed. If not then install
4. Open Recovery and press and hole POWER and VOLUME DOWN button after recovery boots up completely and do not release the keys until fastboot opens.
5. open Terminal(Linux)/CMD(Windows) and navigate into the directory you just downloaded and extracted.
5. Run "flash_all.bat"(Windows)/"flash_all.sh"(Linux).
6. Give it some time and you will get a brand new MIUI 7. After flashing miui 7 you can install any rom you wish.
Let me know if your device gets fixed or if you need any help..
Thanks.

Possibly bricked my poco f2 pro, is there a way to fix this?

Hi all.
Today I unlocked my phone to flash the crDroid rom. First I went into fastboot to flash mauro's twrp and that worked fine. Then I flashed the miui 12.0.3 full stock image from twrp, which might have been a mistake since I flashed the full image instead of an extracted vendor / firmware version. Then I wiped system, cache and data and flashed twrp but when I tried to boot the phone it went into an infinite boot screen. Then I wiped and flashed the whole stock miui image again in the hope that I would at least be able to boot miui but that also failed, since the phone kept booting back to recovery and there was no boot screen at all.
I have also tried flashing the stock image (ver 12.0.6) from fastboot but it fails because of the anti rollback check error. The image I tried to flash has an antirollback version of 0 while my phone has a version of 1, so "current device antirollback version is greater than this package" is what I got. Now my options are very limited because for some reason my laptop can't access the file system of the phone so I can't transfer files to the phone anymore and the ADB sideload feature from twrp is not working, so I only have fastboot (adb also won't recognize my device). What can I do to save my phone? Any help is greatly appreciated.
Flash the MIUI with MiFlash.
Had sort of the same issue...
Try using adbfastboot tool ( it's a java programme ) to swap recoveries.
I got the bootloop after installing the LOS recovery , installed twrp from adbfastboot tool and got it working.
Nice to have working recovery but since adb sideload is broken in twrp i needed LOS recovery.
Tried to reflash the LOS recovery from the tool and this time it worked
Flash with Miflash (the latest version https://xiaomiflashtool.com/ option CLEAN ALL) the rom that was on your phone when you bought it.
For the roms It is better to flash firmwares with Miflash because TWRP is not 100% functional.

Man I can't believe such a simple suggestion would work but it did thanks! Initially I did not flash with miflash because it prompted me to install drivers and it crashed when I clicked the install button, turns out all I had to do was create a folder named log in the miflash directory lol. So flashing the stock image works. And it definitely boots correctly to miui with the clean all and lock option.
But now when I try to flash crdroid or pixel experience I still end up with an infinite boot screen even when using exactly the specified firmware :/ Like you see crdroid and pixelexp boot animations correctly but it lasts forever. I must be doing something wrong with the firmware still because that's the only reason I can think of why it won't boot. After I flash the firmware in miflash I don't have to boot miui up first right? I'm using the 'save user data' option in miflash if that matters.
In my post, I specified CLEANALL, but anyway, you must format data before flashing.
Which rom do you want to install Cdroid or Pixel?

I'm now trying to flash crdroid. After flashing V12.0.3.0.QJKMIXM in miflash with flash_all, I formatted data in twrp (the one where you have to type yes) but also with a decrypt & normal factory reset I still get the same result. After the format, I flashed crdroid without magisk and gapps, and it'll just hang on the crdroid boot screen :/. The weird thing is, before I flash the crdroid rom it can boot in MIUI just fine and it'll show that it's indeed the correct 12.0.3.0 in the settings so I have no idea if it's just the crdroid ROM at this point.
Flash with miflash V12.0.3.0.QJKMIXM reboot system and go fasboot when affiche "devices is locked",flash chinesse twrp ,reboot twrp,format data reboot twrp,wipe all ecxept OTG reboot twrp,flash Cdroid format data,reboot twrp flash gapps,reboot system( take time ).

This ended up working perfectly Crdroid is now running like a charm with gapps and magisk. Thank you guys a lot for helping me out with this!

Why does my device decide to change boot slots from a to b and back at random, preventing lineage starting?

CLEAN install from latest factory, locked and everything, latest lineage nightly.
I installed lineage and then rebooted recovery and installed addons like the guide says.
But every time I restart it's a 50/50 flip if it will try to boot slot a or b, and b won't boot, just lineage logo forever, I have to ADB change it or just restart the phone enough times to fix it.
Pulling my hair out trying to fix this for months.
ANYONE please?
Thank you.
Correct me if I'm wrong, but I think when there's a failed boot, it will fall-back onto the other boot slot.

Did you flash boot.img twice ("fastboot flash boot_A" AND "fastboot flash boot_B")?

Question Flash TWRP and custom rom

today the 168 waiting time has expired and I was finally able to unlock the bootloader. Now I'm trying to install TWRP to be able to install ArrowOS, I do everything I have to do via fastboot, I put "fastboot flash....." etc and all good, when booting, it boots in TWRP, but when I reboot to the system and enter the recovery again I get back the MIUI recovery, something I'm doing wrong? I have tried installing the .img directly from the twrp recovery in the first boot using "fastboot reboot" after flashing and nothing. Should I install the custom rom on the first boot from recovery?
I had the same behavior on reboot into stock firmware when I installed Lineage Recovery. My guess would be that the stock firmware is actually rewriting recovery if it detects that it's not original but I haven't really investigated it.
MIUI recovery didn't come back after I flashed the system image of a custom rom.

Do you install the rom directly after flash the lineage recovery and booting on it? without rebooting or something

If your OS is Official MIUI, the recovery will always be replaced with MIUI recovery on every boot.
Try Orange Fox as recovery, it has an option to prevent recovery from being overwritten by stock recovery, but i dont know wether orange fox works with lineage os. I run it with AICP and it runs like a charm..
I haved the same problem when I haved a whyred (redmi note 5 pro), the solution is very easy, when you have the blue screen of the CMD (now powershell), you need to put "fastboot devices", then put "fastboot boot <twrpfilename>.img, this action will do the device restart in TWRP, then you need to copy and paste the twrp.img in a folder of the device, any folder, it doesn't matter. Then go to install, choose the option "Install image", and go to the folder where you copy the file twrp.img, pick it and choose the option "recovery", then install.
That should be works.
Sorry for my english, I'm trying to learn.
