im fairly new to the rooting scene ive rooted a couple devices before but roms are a new thing to me..
how do i go about installing a rom, such as the unofficial lineage os rom that was made for the honor 6x (in these forums)?
im in the process of unlocking my bootloader and doing a basic root. how can i also acquire a stock firmware and stock rom incase something goes bad and i can restore my device?
thank youuu
*PS is a BLN-L24 model
Follow the instructions carefully mentioned in specified rom page...that should be sufficient but u should be extra careful as this is a kirrin device
Tips...
Remove fingerprints and key on stock rom
Just wipe data, system, cache... don't touch vendoe, product etc when you r going to flash LOS or AOSP
If your going los by hassan - go to advanced wipe in twrp - select data - repair or change file system - ext4 - format
If you are going to elite rom - just format data in f2fs
Rest is very clear in instructions
P.S. - ALWAYS TAKE COMPLETE BACKUP IN TWRP OR ELSE YOU WILL BE F****ED UP
i got it rooted,
now question is, i was looking to do the LOS one by hassan.. do i need to flash in a different twrp recovery other than the one i used in the guide thats posted on here, and if so how can i do so without messing something up? then, i assume hes asking to flash in a new kernel? how?

No need to flash kernel ...It's inbuilt
Yes..u need to flash 3.1.1-1 twrp by hassan ..link provided in that rom page.
Its very easy to flash and more advanced twrp
U could google 'how to flash twrp with twrp' just needs 2 steps
can i just do
fastboot flash recovery twrp-3.1.1-0-berlin.img
but with the other file name for the correct twrp recovery?
ok another question the direction on his post for LOS say to wipe data, the two caches and system and then flash the rom... wouldnt i lose the twrp recovery when i wipe those 4 things?

No it wont. There is no way to wipe TWRP from TWRP (dont clear internal and external storage)
Just follow the instructions carefully.
ALso refer this guide for backup in case you messed up (method given for backup)
ok so problem. i followed his instructions to a T, and its stuck at the boot animation i also made sure to change the data partition type to ext4

Hi guys i need a big help
I'll try to explain all but i'm not good in English
i bricked my honor 8 L09
it happened when I tried to restore a twrp backup. Twrp can't continue the restore because "cust" can't be extracted
So i tried to restore the backup deselecting cust part
And this was my error
Bootloop
So i tried:
-restored others backup -FAILED-
-used Huawei eRecovery : "getting Package from server failed" -FAILED-
-flashed roms, aosp and emui based, marshmallow and nougat based: can't flash -FAILED-
-flashed boot.img, system.img, recovery.img nothing worked -FAILED-
-extracted cust.img and flashed via adb folllowing this guide: https://forum.xda-developers.com/honor-5x/help/how-restore-cust-partition-t3356769/page2 flashed but nothing works -FAILED-
But now is worse, because i can't get into twrp but only in eRecovery (that doesn't work), and adb flash don't work
What can i do?
Maybe a huawei/honor repair shop can help me?
Follow this guide https://forum.xda-developers.com/honor-8/how-to/guide-honor-8-to-frd-l19-t3632220.

-tried to flash the stock rom linked in your guide but it flash only oeminfo
If u are talking about the guide I linked, I did all steps (my bad, I think that this is the problem, because the modified file in this guide block me from wipe)
EDIT: just tried to flash via fastboot all the .img one for flash but every single time it says "failed. Command not allowed"
Bro go to twrp > advance wipe (all )
If error again reboot again and format data and again advance wipe.
Now flash this link https://drive.google.com/file/d/0BwXB-CJiljwpS1o4UXo5b1JlRjQ/view
After that do a reset and reboot ,you will be successfully unbricked

Make sure your Bootloader is Unlocked
Reboot to Bootloader (Hold Power + Volume down) until you see Fastboot Image
Dowload latest TWRP by Mohancm https://www.androidfilehost.com/?fid=818070582850498337 copy to ADB folder
Goto your ADB folder (hold shift + right click) open with CMD / Powershell
Type Fastboot boot re (press tab for recovery shortcut)
Press enter don't close your window
In TWRP Allow Modification
Goto to Wipe > Advance wipe > check System/cache/data/internal and swipe to wipe
Don't reboot yet > goto reboot option and choose Bootloader
Goto CMD/Powershell just press Up arrow key and enter
Copy the ROM/GAPPS/MAGISK to you device
Flash ROM
Reboot to Bootloader
Goto CMD/Powershell just press Up arrow key and enter
Flash GAPPS/MAGISK
Reboot to System
Profit!
Great. Much appreciated :good:
In step 3 after flashing rom , what about reboot to recovery instead of reboot to bootloader and flash twrp again?

Yes but it also installs the OS as well. You want a clean slate completely, if possible, so best to wipe it again before flashing a custom ROM.

May be it has to do something with files written when you boot N 1st time. Like temp files.

Its for the encryption. So if you flash custom roms it doesnt show "data is encrypted" in your first boot. Thats what i've read.
You can always try flashing without wiping internal and see.

Good day! Never failed to flash the rom in this way, the rollback to the nougat is made, the necessary recovery is loaded - an error 1. Tell me what might be the matter?
first, can i flash rom on both partion a and b ?
why after flash and rebooting to twrp again pation change to B?
why not flash magisk and gapps on same partion with first installation?

-Do not flash it on both slots.
-The reason it switches between A and B, is because the rom gets installed on the second partition and not the partition you are on when you flash it (i think).
-And you can't flash magisk or gapps because, like what i've said before, the rom gets flashed on the other slot.
Im not 100% sure that's how it works, so don't quote me.
I've flashed viperos having no issues. I had flashed nougat firmware before that. Now in order to flash another rom, do I have to flash stock nougat firmware again or is it ok that I just clean wipe and flash new rom?

Dude just boot to twrp -> Wipe -> format Phone -> type yes -> DONE! Now reboot twrp again and flash magisk. Ano it should boot fine. It's because of Samsung's DM-Verity and force encrypt.
PS: Formatting phone will delete all ur data on the phone including files on internal storage like pictures, downloads, etc. So keep a backup.
I'm finish unlock bl and i want to install custom rom. I already flash TWRP and it have no storage
so I go to wipe and format data (type "yes") now i have TWRP storage.
The problem is when i finish flash rom and i want to go back to TWRP to flash SuperSU, My TWRP storage is gone again.

BUGS:
- ADB
This recovery is only for Android 9, if u updated A20E to Android 10 u can't flash this recovery.
According to some users it can work on Android 10 but I don't guarantee booting to your stock system but u can install straight GSI
1. Make sure u have rooted phone, if not check this guide https://topjohnwu.github.io/Magisk/install.html#samsung-system-as-root or/also this https://forum.xda-developers.com/galaxy-a20/how-to/root-samsung-galaxy-a20-rooting-guide-t3954872
2. You gonna lose all of data.
3. Make sure u have checked OEM unlock in settings
4. Reboot phone to android/stock recovery (u can use: adb reboot recovery), wipe data/cache and straight after this select "Reboot to bootloader"
5. Plug telephone to computer, start Odin(use v. 3.13.x) add recovery.tar to AP slot, click start and immediately click and hold POWER and VOLUME UP until TWRP logo pop up.
6. Format Data (not just wipe) - don't restart (idk if needed but do it for safety)
7. Use MTP to put Disable_Dm-Verity_ForceEncrypt_03.04.2020.zip and flash it, system should start normaly. (i didnt checked on stock, i straight installed GSI)
Now u can flash GSI ROM(use only A/B): https://forum.xda-developers.com/galaxy-a20/how-to/gsi-galaxy-a20-t3964546
Flash .img and after this flash GSI_Fix_boot.zip, wipe cache and restart to system.
AND NOW MOST IMPORTANT PART:
Find your build number in software information.
A202FXXU3ASL4 means U3
A202FXXU2ASJ3 means U2
IF U HAVE U3/S3 BOOTLOADER FLASH THIS TAR:
https://mega.nz/folder/LTZlUKyI#oxxVc5zj8tP4bNQBIo8AlA
IF U HAVE U2/S2 BOOTLOADER:
u need to compare alphabetically 3 last characters of build number(NOT CSC!) with A202FXXU2ASJ3
for example your build number is A202FXXS2ASI3 so last 3 characters are ASI and u need to compare it with ASJ -> first and second letter are the same, so go to third, letter I in alphabet is before J, so u have older firmware and u need flash this tar(eg. ASH, ASG, ASF):
https://mega.nz/folder/nDZUwS5A#_FQKWL_1QUHN8_wXgqdGBw
if u have at least A202FXXU2ASJ3 or newer(eg. ASK, ASL, ASM) or firmware flash this tar:
https://mega.nz/folder/7bZ20IAY#ewz5ZZzWxTJfAbcnEJgAZA
I DIDN'T TESTED NEWER U2 AND U3 BUT IT SHOULD WORK FOR 99%

U need to do twrp device tree, u can use prebuilt kernel or straight from source, and u need dtbo image if ur bulding on android 9+. I too get bootloops but key is to use right version of kernel appropriate for ur bootloader version. There is massive difference beetween old U2 and new U2 and maybe that why ur twrp gets bootloop. Also u need fix for himax touchscreen to work in recovery mode. I make public sources of my work also with commits.

Thank you for answering. Are there no plans for developing for android 10 a20e? When I install ur u3 bootloader twrp, it shows twrp logo. And its stuck there. Can you make one using android 10 sources? Or you don't want to take risks not testing it, can you share ur files like ueventd.rc , boardconfig.mk? So I can make one. I am not so sure about my flags and ueventd.rc files...

Can you make one using android 10 sources? Or you don't want to take risks not testing it, can you share ur files like ueventd.rc , boardconfig.mk?

Samsung didin't for now make public any android 10 kernel sources for A20e, if they do it public i gonna try. Oh, if u get splash screen it means u have still data encryption, did u before flashing twrp wiped in stock recovery data/cache, if it boots to splash screen its really big chance it gonna work for you and also for others.
uevent.rc just pick up from any exynos7885 device tree, also BoardConfig.mk are really the same, as a10 or a30.

Wow. It worked. You can edit that it works for android 10 too. One question. Why the system partition is mounted read-only and can't be changed? I want to re-partition /system to install google r preview gsi
Edit: Search: On android Q, We can't mount /system rw.....

Android 10 is formatted with EXT4_FEATURE_RO_COMPAT_SHARED_BLOCKS which is blocking to mount system partition as rw.

Team Win Recovery Project for Galaxy A20e (A202F)
BUGS:
- ADB
This recovery is only for Android 9, if u updated A20E to Android 10 u can't flash this recovery.
According to some users it can work on Android 10 but I don't guarantee booting to your stock system but u can install straight GSI
1. Make sure u have rooted phone, if not check this guide https://topjohnwu.github.io/Magisk/install.html#samsung-system-as-root or/also this https://forum.xda-developers.com/galaxy-a20/how-to/root-samsung-galaxy-a20-rooting-guide-t3954872
2. You gonna lose all of data.
3. Make sure u have checked OEM unlock in settings
4. Reboot phone to android/stock recovery (u can use: adb reboot recovery), wipe data/cache and straight after this select "Reboot to bootloader"
5. Plug telephone to computer, start Odin(use v. 3.13.x) add recovery.tar to AP slot, click start and immediately click and hold POWER and VOLUME UP until TWRP logo pop up.
6. Format Data (not just wipe) - don't restart (idk if needed but do it for safety)
7. Use MTP to put Disable_Dm-Verity_ForceEncrypt_03.04.2020.zip and flash it, system should start normaly. (i didnt checked on stock, i straight installed GSI)
Now u can flash GSI ROM(use only A/B): https://forum.xda-developers.com/galaxy-a20/how-to/gsi-galaxy-a20-t3964546
Flash .img and after this flash GSI_Fix_boot.zip, wipe cache and restart to system.
AND NOW MOST IMPORTANT PART:
Find your build number in software information.
A202FXXU3ASL4 means U3
A202FXXU2ASJ3 means U2
IF U HAVE U3/S3 BOOTLOADER FLASH THIS TAR:
https://mega.nz/folder/LTZlUKyI#oxxVc5zj8tP4bNQBIo8AlA
IF U HAVE U2/S2 BOOTLOADER:
u need to compare alphabetically 3 last characters of build number(NOT CSC!) with A202FXXU2ASJ3
for example your build number is A202FXXS2ASI3 so last 3 characters are ASI and u need to compare it with ASJ -> first and second letter are the same, so go to third, letter I in alphabet is before J, so u have older firmware and u need flash this tar(eg. ASH, ASG, ASF):
https://mega.nz/folder/nDZUwS5A#_FQKWL_1QUHN8_wXgqdGBw
if u have at least A202FXXU2ASJ3 or newer(eg. ASK, ASL, ASM) or firmware flash this tar:
https://mega.nz/folder/7bZ20IAY#ewz5ZZzWxTJfAbcnEJgAZA
I DIDN'T TESTED NEWER U2 AND U3 BUT IT SHOULD WORK FOR 99%

Yes you need to do this because of data encryption and if u dont do that u gonna get stuck at splash screen. Just pick up U3 recovery.

Ehh, enable debugging in programming options, then connect to computer and write in cmd: adb reboot recovery(if u dont have adb - install it), after wipe cache/data click reboot to bootloader and follow the instruction.
