boot problems 5.5.22 Mi Note Pro

Hello,
my Mi Note pro worked fine at the beginning, running the latest stable ROM.
I then installed 5.5.22 Developer ROM which also worked fine.
For some reasons, I then downloaded "Minimal ADB and Fastboot" and flashed the recovery.img - since then the device does the following:
* does not boot beyond the Mi Logo
* can boot into Fastboot mode
* cannot boot into recovery mode (volume up + power) - it once did this somehow, as I saw the screen flickering and could see the 2.0.1 recovery version in red below
I then flashed the device with the 5.5.22 Fastboot ROM, which worked fine. But the device still does not something different then the three points above.
I then updated the device with the Mi PC Suit to the satble and also again Developer ROM which worked, but the deivice still did not boot.
I then flashboot flashed the 5.5.22 recovery and boot.img, but again, nothing changes. The deivice can boot into Fastboot, but not into recovery and also does not boot normal.
Any suggestions, what I could do? I tried so far absolutely everything, but maybe I forgot somethign important.
regards,
JJ

There is no working recovery other than what comes from official MIUI firmware, it is possible the bootloader refuses to load unauthorized firmware. You are going to probably need fastboot ROM images

MiPhone will do it for you if it detects the phone is in Fastboot mode

I have messed up my recovery. It shows TWRP only. On the next update, it didn't proceed from MI logo. My MAC doesn't work with Fastboot in recent days. I will use the above with my friend's PC.

I bricked my honor 9 lite

Please help.......give me a guide to flash stock ROM by fastboot mode.....also please provide the fastboot commands
:crying:

Do you have fastboot and frp unlocked?

Yes it is frp unlocked

Check my answer in this thread.
Hope it helps! And if it does, please hit the Thanks button.

please try this :
- download full update rom for your device, extract the .APP files using HuaweiUpdateExtractor
- boot into fastboot by press and hold Volume Down and plug in usb cable into your pc and your phone, hold it until it boot into fastboot
- do this :
fastboot flash kernel kernel.img
fastboot flash ramdisk ramdisk.img
fastboot flash recovery_ramdisk recovery_ramdis.img
fastboot flash recovery_vbmeta recovery_vbmeta.img
fastboot flash recovery_vendor recovery_vendor.img
fastboot flash system system.img
fastboot flash vbmeta vbmeta.img
fastboot flash vendor vendor.img
- reboot your device and hold Volume Up and Volume Down to get it boot into eRecovery and do Wipe Cache Partitions and then do Factory Data Reset, and reboot again
- let it boot normally, and see what happen next, i can't remember for sure because it's been so long i unbricked my Nova 2s with this method. there are 2 possibility, you'll boot into system normally, or it will boot into eRecovery again and there is an option Download Latest Version And Recovery and you can choose that, of course you should have connection to internet via wifi.
please report back if you have difficulties.

Hi, please don't ask me how I did this but I somehow hardbricked my phone, Model: LLD-L21
currently status is literally a brick, screen doesn't even turns on, holding keys doesn't lead to anything, Only thing I have is fastboot command, in fact when I connect my phone to PC, I hear connecting sound from windows and fastboot drive is up, (even in bootloader the screen is off) so what I have:
FRP is unlocked
Bootloader is unlocked
last installed firmware was EMUI 8
working fastboot
literally nothing more, how can I unbrick this brick my own?
[update]:
I tried your solution but at last part, vendor cannot be flashed (Command not allowd) and I guess no hope

Do you have single or dual sim device? The custom rom you mentioned was Oreo?
---------- Post added at 04:18 PM ---------- Previous post was at 03:59 PM ----------
You need microSD card. Copy these files to microSD, make new folder "Oreo" and put all 4 zip files inside.
-Download update.zip.
-Download update_data_full_public.zip (rename to ''update_data_public'').
If you have single sim device, then
-Download update_full_PRA-L11_hw_eu.zip (rename to ''update_all_hw'').
If you have dual sim device, then
-Download update_full_PRA-L31_hw_eu.zip (rename to ''update_all_hw'').
-Download HuRUpdater
-Download Oreo version of TWRP
Boot in fastboot mode.
Run this command to flash TWRP
fastboot flash recovery_ramdisk recovery_1105.img
Reboot with fastboot reboot
Boot now into TWRP, click install, select microSD, select to flash ONLY HuRUpdater.zip.
Reboot.

Yes man i did it pretty well !so for the peoples who got the same problem than me and got stuck
on the fastboot&rescue mode when VOLUME- + POWER for like 5 seconds with the phone off
(for the peoples who can't power off your device you can download the "universal fastboot and ADB tool" app and then click on reboot phone in the fastboot part)
the solution is to :
-Download the rom stock Oreo android 8.0 stechguide.com/huawei-p8-lite-2017-b370-oreo-firmware/
-exctract all files from the HuaweiUpdateExtractor find it on google it's easy just download update.zip
-extract and put the UPDATE.APP in the HuaweiUpdateExtractor
-run srk tool for huawei
-type 000 and press enter
-and now you have to flash all partitions that you have received from HUE commands are here:
[dont worry if some of theese are not working it's because certains commands are not allowed to use and certains commands are out of date :/ but dont worry the phone will boot correctly after ]
Code:
fastboot flash cache CACHE.img
fastboot flash crc CRC.img
fastboot flash curver CURVER.img
fastboot flash dts DTS.img
fastboot flash efi EFI.img
(i'm not putting erecorery imgs cause we cannot touch them it's an ultimate security from os :) )
fastboot flash fastboot FASTBOOT.img
fastboot flash hifi HIFI.img (only if you are the wifi is not working ;) )
fastboot flash kernel KERNEL.img
fastboot flash modem_fw MODEM_FW.img
fastboot flash modemnvm_update MODEMNVM_UPDATE.img
fastboot flash odm ODM.img
fastboot flash package_type PACKAGE_TYPE.img
fastboot flash product PRODUCT.img
fastboot flash ramdisk RAMDISK.img

fastboot flash trustfirmware TRUSTFIRMWARE.img
fastboot flash vbmeta VBMETA.img
fastboot flash vendor VENDOR.img
fastboot flash verlist VERLIST.img
fastboot flash xloader XLOADER.img
Now you have loader all partitions of an huawei p8 lite 2017 android 8.0 gg !
you just have to make a fastboot reboot to reboot your phone and enjoy !
notes:Everything is working properly after 3 day of use not any missing data some calls bugs but nothing hard
you will loose your TWRP recovery mode AND DO NOT INSTALL ONE OF THEM FOR NOW they are outdated for oreo wait some months (september on some sources)
you will loose all your data and the root (some sites prupose root methods for oreo p8 lite 2017 (and soft root this time :laugh:
idk about the bootloader but i keeped my imei number ^^
Thanks for your time and if anyone got questions i'm still here ^^

I saw you have to let the phone shutdown itself ( battery to 0 ) and then plug it to charger or PC and the recovery will return, don't know if it will work for you but just my 2 cents.
I had the same problem after replacing the recogery with *fastboot flash recovery2 recovery.img* but my phone booted to android out of the blue so I didn't use that command, yet.

I myself accidentally installed another TWRP.img to my recovery_ramdisk partition. Although my phone boots up and I can use it, I can't boot into my recovery anymore. It just stays at the "Your device has been unlocked" screen.
Fixes?

Cannot flash system.img on global rom

Hey I am bricked my device I am was on global rom and then wanted to convert to Chinese rom tried to flash it through system update.. And now stock on fastboot forever until now.. I am tried to flash system. Img of Chinese rom.. Got message that file too big in adb.. There is any program to compress this img?

Local update didn't work because of mismatch boot.img and recovery.img. In fastboot flash CN boot and recovery then reboot recovery, wipe data and cache, insert OTG with CN.zip package and install.
***When switching region ROMs always do this method from recovery, local update does not handle this well at all and fails most times.
***If you want you could also try EDL mode, I never tried it but theoretically the command "adb install N629J-update.zip should work. I have not tried this method but that's what EDL mode is for ?

Even i had the same issue. First make sure you are using the latest version of ADB and Fastboot. Use 1.4.3 or higher. Sometimes it will be installed in C:\Program Files(X86)\minimal adb and fastboot Folder. Copy the img files to this location and then flash the image.
Download necessary files https://drive.google.com/drive/folde...Ym?usp=sharing

fastboot flash recovery recovery.img
fastboot flash splash splash.img
fastboot flash system system.img
fastboot reboot
When you flash system.img you should get a warning message. Don't close the window. Wait for sometime. It should split the file upload as 5 parts. Once all the 5 parts are uploaded. Then type fastboot reboot. Then remove the charging cable(very important) and you should get the normal warning message and then phone will try to boot. Once you get the splash screen and booting screen. Press volume Up and power together. It should go to default recovery. Select English. Wipe data and then wipe cache. Reboot. Now your phone should boot normally. Hope this helps. Good luck.

Pm me i know how to fix

I managed to boot too TWRP.
I had to patch it from fastboot, then boot to recovery with VolUP, then make wipe and hold still VolUp.
Seems like EMUI patched, so P20 is back!

Everything unlocked, but I have a black screen!
