Sorry, wrong link. twrp-ldn-64bit-all.img
This one got working MTP, but something else is not working (adb I guess).
*.emmc.win is ext4 image, same format as *.img.

New TWRP v.3.3.0-0 for London. Mirror on AFH.

Works: Backup, restore, install zip/img, MTP, OTG, ADB, Sideload, format, wipe, etc.
Not work: FBE (suggestion: remove dm-verity and forced encryption).

Tipatched TWRP to include Internal SD in backup/restore/wipe/format: @ AFH

All drivers could be found in HiSuite 9.1.0.300_ove (latest).

@adeii , can you make a new backup for "firmware-modem"? Made a restore using the files from one of your threads and now EMUI doesn't even want to recognize the sim card slots due to "Failed to enable SIM Card slot". Also, rip my OEMinfo partition.

UPDATE 1: RIP GSIs don't even recognize the SIM card slot

Just fyi, the firmware-modem failed the flashing due to it failing to extract the backup which was firmware.vfat.win.

UPDATE 2: I think it was something else, does anyone have a clue on what's happening? Looks like I have to stick with Wi-fi and no mobile data

Not a problem. New back up with FW-ddumper and TWRP 3.3.0.0.
fwdd-backup
twrp-backup

Maybe some partitions have bad definition:
Code:
/firmware         vfat        /dev/block/bootdevice/by-name/modem    flags=display="Firmware-modem"
/modem           emmc    /dev/block/mmcblk0p37                                  flags=display="Modem";backup=1;flashimg
/oeminfo          emmc    /dev/block/mmcblk0p30                                 flags=display="OEMinfo";backup=1;flashimg
/modemst1      emmc    /dev/block/mmcblk0p32                                  flags=display="Modemst1";backup=1;flashimg
/modemst2     emmc    /dev/block/mmcblk0p33                                  flags=display="Modemst2";backup=1;flashimg
Online system list does not have /firmware, but it has /modem, /modemst1, /modemst2 as defined as above. Firmware line is sufficient!
So, ignore to restore /firmware but restore /modem. Since it is in emmc format, it should be full "image" to flash, not just files.
About SIM card: I use EU region, firmware C432, dual SIM.

Well, just got this message after sending my device to the service center. Looks like I’m gonna wait for the device for about two days. Good thing it’s still under warranty (even though I unlocked the bootloader).

Sorry to hear it. Did you try to restore it with eRecovery or HiSuite by yourself ?!

eRecovery died. Couldn't get to recovery and bootloader was FRP locked so no way of getting to device.

Good thing this device was under warranty. In return they changed the whole motherboard of the device. Meaning that IMEI and SN was changed.

Looks like I'm going to wait for a week before paying MOS to unlock my bootloader again.

@EzzUsesAndroid
Does you wide-focus rear camera (2 MPx) work on Permissive-kernel in stock Camera app ?!
I have lost that option, all I got is Beautify on both front and rear camera.

UPDATE: Restored backup from april, everything works fine.

Diffs in defconfig between L21 and LX2 are:
CONFIG_HZ=300 vs 100
CONFIG_HUAWEI_PROC_SMAPS_SIMPLE=y . . . . vs . . . . . n\a
CONFIG_FRAME_POINTER=y . . . . vs . . . . . n\a
CONFIG_WBT=y . . . . vs . . . . . n\a
