How to remove data encryption on emui 9.1 stock roms and root

[brokenworm]

Im Using C432 .. Rom 9.1.0.147 Newest Stock Update Here In Denmark

First Unlock Bootloader : flash oem unlock ********code******
Enter Bootloader Again, Now Flash Modded_recovery_ramdisk : fastboot flash recovery_ramdisk r.ram.mod.img
And Flash Erecovery_ramdisk with TWRP.img From kilroystyx

Do NOT Remove USB Cable But Hold Power Untill You See Black Screen
Then Quickly Pres And Hold VOL + Untill You Read "Your Device Is Booting Now..."

Now You Should See/Enter Your TWRP Recovery , Now Wipe And Format Data, Then Reboot Recovery "Force Close With Power" .. Again When You See Black Screen Then Quickly Pres And Hold VOL + Untill You Read "Your Device Is Booting Now..."
And You Should ReEnter TWRP Again.. now Mount Vendor then Start Terminal In Recovery under advanced
In Terminal Type :
mount -o remount,rw /dev/block/mmcblk0p55
mount -o remount,rw /dev/block/mmcblk0p37
mount -o remount,rw /dev/block/mmcblk0p53

"patition name/table layout of editable partitions from recovery"
cust = mmcblk0p53
vendor = mmcblk0p55
modem_fw = mmcblk0p37
erecovery_ramdisk = mmcblk0p29
recovery_ramdisk = mmvblk0p33

Now Use File Manager In Recovery Under Advanced To Copy fstab.modem , fstab.hi6250 And recovery.fstab From /vendor/etc/ to /sdcard/ And from /sdcard/ Over To a PC .. Edit fstab.* With Notepad++ One By One Remove The Word "verify" including the comma and replace ALL "ro" with "rw" Also Remove The Words With fileencryption***************** Including The Comma ...
Do This in ALL 3 Files When Done Copy Back The 3 Files To Sdcard And Use File Manager To Move The Edited Files Back To /vendor/etc/ Overwriting The Old Files Now Do The Same With The 2 Files In The Root /fstab.hi6250.data And /fstab.hi6250
THEN FROM RECOVERY Select REBOOT And RECOVERY .... AND YOUR DONE .. You Should Now Automaticly Enter The Rom..

YOU ARE NOW MAGISK ROOTED "Use 19.3 Stable Settings In Magisk Only" Dont Directly Update Magisk ! Clear Repo!

From Now On To Enter The TWRP You Need To Put The USB Cable In The Phone And Hold VOL- And Power To Enter Bootloader From Here Force Power Off " Hold Power Untill Black Screen Then Quickly Hold VOL+ Alone Untill You Read "Your Device Is Booting Now..." Only Way To Enter TWRP Using "ERECOVERY_RAMDISK" Partition.. And Always Use Reboot Then Recovery to Enter Rom From TWRP .. If Not You Need To Reflash recovery_ramdisk with r.ram.mod.img

Now You Can Backup Data And Restore Data With Out Fork Errors We Should Also Be Able To Both Backup/Restore Cust , Modem_fw And Vendor. But We Only Need Data, System , Erecovery_ramdisk And Recovery_ramdisk To Get A Good Complete Backup.

Becoes your new ill be nice.. but plz dude.. u got to read more before you use this guide or you will end up with a pretty door stopper.

To unlock your bootloader use this DC UNLOCKER CLIENT : https://www.dc-unlocker.com/downloads
This is the 1 and only solution .

Welp, i managed to flash twrp to Erecocery, it's pretty easy

1 download twrp and patched recovery_ramdisk (i strongly recomend to extract the one from update.app with huawei firmware finder and huawei firmware extractor and pacth it with magisk manager)
2 copy twrp.img into your minimal adb folder and copy twrp and patched recovery_ramdisk into your micro sd
3 connect p20 lite (in fastboot Mode) to pc and open minimal adb and fastboot (cmd here) and flash twrp (fastboot flash recovery_ramdisk twrp.img)
3 Disconect and force power off, turn p20 lite and boot into recovery (power off and vol +) it Will boot into twrp
4 go to install and go to external storage, also select "Install image"
5 select your twrp.img, it will you ask where to Install, select "Erecocery_ramdisk" and Install it
6 repeat step 4 and now select your patched recovery_ramdisk.img and Install it on "recovery_ramdisk"
7 ???
8 profit

And now i'm stuck with the fstabs, i do all the steps on first post but when i try to move the modified ones shows an error, so what now?

i would try remounting the partitions rw

Hi. The code I wrote from the twrp terminal window gives an error.

mount -o remount,rw /dev/block/mmcblk0p55
mount: can't find /dev/block/mmcblk0p55 in /proc/mounts

When you enter "ls -l /dev/block/mmcblk*" in the terminal, what does it say then?

I want to transfer this procedure to Honor 7X. Can someone please send output from the following commands (first to get list of names of partitions, second to get list of mounted filesystems) executed via adb shell on the P20 lite:
ls -l /dev/block/by-name
mount

Thanks a lot in advance.

the partitons change from rom build to rom build and is useless. ..

i moved on to new device sry ..
but this is the partitions i was playing with :
"patition name/table layout of editable partitions from recovery"
cust = mmcblk0p53
vendor = mmcblk0p55
modem_fw = mmcblk0p37
erecovery_ramdisk = mmcblk0p29
recovery_ramdisk = mmvblk0p33

Does anyone have a working link to the r.ram.mod.img file?

EDIT: Nevermind... figured out I had to extract it from my firmware.
