Question OTA Fail on LE2120 running OOS 11.2.9.9.LE15AA

[Cye3s]

Some days ago I receive OTA to 11.2.10.10.LE15AA(phone rooted)，because I change Magisk package name, so OTA package is about 125MB
I open Magisk, select “Uninstall”, and choose the “Restore Images” option.
I download OTA and install it.
Then open Magisk , first "Dirrct install(Recommed)", then "Install to inactive Slot(After OTA)".
Then reboot.
But boot failed, so I went to fastboot.

fastboot --set-active=b
fastboot reboot

Phone boot into old version 11.2.9.9.LE15AA

I try to download full zip use Oxygen Updater, then file name is:
a074a7205a681509f1b84d6a2e0f75ddc2c6ab9b.zip
then payload dumper, get then origen boot.img
Upload to phone, pack it with Magisk, send to PC

then went to fastboot

fastboot --set-active=a

fastboot flash boot magisk_patched_xxx.img
reboot, still fail
fastboot flash boot boot.img (origen boot.img)
reboot, still fail

So I

fastboot --set-active=b

try to flash full zip(a074a7205a681509f1b84d6a2e0f75ddc2c6ab9b.zip), but get error message.
Check Update, tell me have new version ，but with some problums, need to reboot to fix it, reboot, not work.

fastboot getvar all

Some usefull lines:

(bootloader) current-slot:b
(bootloader) has-slot:boot:yes
(bootloader) slot-retry-count:b:7
(bootloader) slot-unbootable:b:no
(bootloader) slot-successful:b:yes
(bootloader) slot-retry-count:a:7
(bootloader) slot-unbootable:a:yes

now get dead loops

when Check Update, tell me have new version ，but with some problums, need to reboot to fix it, reboot, not work.

If I start local update with full 11.2.10.10.LE15AA zip, then failed.

Updates you got is incremental. Get the full 11.2.10.10 from sticky threads above place it to your SD card then local update

I got the full file from your thread, the download file is a074a7205a681509f1b84d6a2e0f75ddc2c6ab9b.zip
but something wrong when I start local update.
