Bootloop after MM preparing update - Desire 820 Q&A, Help & Troubleshooting

Hello,
I've recived ~66MB update which fixes MM update bug (not part 1/2 MM, update before that). I unrooted my phone, flashed stock recovery and updated.
1. I tried to flash stock recovery using
fastboot flash recovery recovery.img
Click to expand...
Click to collapse
but it failed so I used
fastboot erase cache
Click to expand...
Click to collapse
and
fastboot flash -S 512M recovery recovery.img
Click to expand...
Click to collapse
and it worked. I booted to recovery just for sure - all OK.
I booted to the system, updated, but after update my phone is stuck into a bootloop. When pressing any button it vibrates. The only way to reboot is to press Power + Vol+ + Vol-. Any help?
EDIT:
HBOOT and recovery works. I have a system backup before the update.

Disregard. Not putting recovery in the right folder. Little mistakes make me lol.
Edit again, this recovery doesn't work for me. I flash it but when trying to get in to it, it just bootloops once then boots up normal.
Do you have the L09 variant?
It works for me, that's strange.

Yes I have the L09. I tried flashing it several times and each time, it bootloops once then boots up normal.
Just use my tool. So you can then flash the custom Rom.

that fixed in comparison with previous builds ?

Can I use your tool without unlocking the bootloader on my MT7-L09?
No, but there will be instructions.
Tried this but failed to install CWM .. seems like all are failing? Is there a certain firmware that the phone needs to be on?
Hi all, i flash cwm_mate7_20150410.img but don't boot in recovery mode.Any idea?
Ciao

Hi,
I have a MT7-L09, I unlock bootloader and I installed TWRP but I can't flash anything because I encrypted my phone.
Does this CWM recovery handle mounting encrypted partition?

Common issue
Boot into edl mode and flash 8.1.3.0 fast boot image and then you will be able to flash twrp again

I think you don`t need to flash all the fastboot image to can flash TWRP again, just flash via fastboot, place your recovery in ADB folder, rename it recovery.img, fastboot will flashed but it seem that recovery it`s missed but the trick it`s only that don`t boot to recovery if you don`t execute after flash recovery the next command in fastboot: fastboot boot recovery.img, when you boot to recovery wipe cache and dalvik cache if it`s necessary three times untill recover your usual settings like language, bright and others.

Stock recovery automatically replace

Goodmorning, I've a strange problem with flashing recovery.
I used lastest fastboot
I've flashed the recovery (fastboot flash...) Then booted into it directly (fastboot boot recovery...) And obviously problems with mounting data.
The real problem is that when I reboot system , twrp is automatically erased and stock recovery is mounted.
I've tried everything, new recovery,new fastboot...
Please help me
That's standard with a lot of OEM ROMS on many different phones. You can flash magisk or SuperSU to preserve your flashed twrp.

That won't work, the no-verity-opt zip is needed to preserve twrp or it will always revert back to the stock one.
Go here

- flash latest twrp https://twrp.me/xiaomi/xiaomimimix2.html
- reboot to recovery with hardware keys (volume-up + power) immediately after flashing
That solved the problem for me.

The first boot after flashing TWRP need to be into recovery so TWRP could use his scripts to block the automatic restore of the stock recovery.
Also try the last TWRP version 3.2.1

Done this several times, but I didn't use hard buttons, instead i used fastboot boot recovery.img command to reboot to recovery after flashing recovery. I also tried rebooting to recovery from twrp without problem, but after rebooted to system, twrp reverted to stock recovery, everytime.
I didn't have this problem with MIUI 10.3.1.0 with the same TWRP.
edit : I'm using TWRP 0330 btw, and somehow there was no swipe to allow modification confirmation when the phone rebooted to twrp for the 1st time after flashing twrp.
Wonder why.

Tks, but I don't have problem with TWRP 0330, it works fine, including touch screen, the problem is TWRP get replaced by Stock Recovery everytime I boot my my phone to system.
I don't want to root my phone, just like to have TWRP recovery around so I can use it to flash hosts file for ads blocking and some other things.
Someone told me i need to flash lazyflasher...I'm going to do it later ..

Boot to recovery through fastboot and then flash the image or the zip through TWRP, then to flash it reboot again to TWRP before to boot up to system.

No. don´t try to boot to recovery from fastboot after to flash it, don´t flash it through fastboot.
Do the next three steps and see what happens but do it exactly the same or won´t worth the try:
- In fastboot delete recovery partition by typing fastboot erase recovery
- Then reboot to recovery (don´t flash it yet) by typing fastboot boot twrp.img (rename recovery image firstly to twrp)
- Now once in TWRP flash the zip or image to the recovery partition, when you finish go to Reboot options within TWRP and choose recovery to boot to it before to boot up to system. If you boot at this instance to TWRP then the issue have to be solved, reboot normally to system.
Edit: If this way the problem is not solved then after to install TWRP flash Magisk that can prevent it to be overwritten.
