For those who wish to update without losing the data, know that the dev of Magisk no longer recommends to root via twrp on recent models it is now necessary to patch the AP file with magisk (apk) before Odin flash for each update follow the installation guide...👇

https://topjohnwu.github.io/Magisk/install.html
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] arlequin2k3:
Thanks for the advice , I just did it and it works .
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] relax24:
Where does vbmeta come in to this. There's no mention of it in the above instructions
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] bininga59:
With the S10 it was like this:

"Open Odin v3.14.1 and place the downloaded TWRP .tar file in AP tab, downloaded vbmeta .tar file in CP tab and click Start - once you press start grab the phone and press vol up + bixby + power to force it boot straight in TWRP after flashing"
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] relax24:
Right but are we saying vbmeta is or is not required just to root. The magisk instructions don't mention anything about vbmeta
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] arlequin2k3:
I confirm it, I did not use vbmeta .tar .
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] Full House:
Apparently there is no need for vbmeta the requirements for this method is that only the bootloader is unlocked ... on the other hand if you want to persist in rooting via twrp you will have to systematically flash vbmeta + multidisabler + erase data ... it seems to me that the twrp of this thread is no longer compatible with the latest OneUi versions
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
the guide on github says that only the first install of magisk needs a wipe (via Odin). I don't get this idea that you can use TWRP after to flash magisk, colour me confused!

To upgrade your device with a new firmware, NEVER directly use the stock AP tar file with reasons mentioned above. Always pre-patch AP in the Magisk app before flashing in Odin.

Use HOME_CSC to preserve your data when doing a firmware upgrade in the future. Using CSC is only necessary for the initial Magisk installation.

Never just flash only AP, or else Odin can shrink your /data filesystem. Flash full AP + BL + CP + HOME_CSC when upgrading.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] Full House:
Exact but with the Magisk.zip method via twrp you always have to reset the data to update ...
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
what is the magisk via TWRP method though ?
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] Full House:
Flash Magisk via twrp like we did on older devices.

We can install twrp when it is corrected to hopefully install custom rom in the future.

Basically it is now recommended for Samsung ROM to patch the firmware AP file to root this is all you need to understand
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
I understand that part, I thought v21.4 was done for phones that came out with android 10+

looks like there's no reason to use TWRP after the first root if you still have to use Odin AND wipe data.

hopefully any custom roms will now be made with pre-patched ramdisks and you just install v22 magisk.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] afaneh92:
Guys! This is not root or magisk thread.

The instructions for TWRP in OP, Don't mix with magisk instructions. And dont tell me that disabling vbmeta not required when you already disabled it by patching AP.

I've tried to flash the UK firmware on my fe 5g and it keeps saying failed, I mean iv done these steps plenty of times on my other samsungs with no issues, can someone post a link to a guide on here to flash a different firmware, maybe I'm using the wrong odin or frija tool but I dont think so
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] afaneh92:
You cant flash different firmware, only same model G781B only for example.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] b1k3rdude:
Whats the exact model number of your S20FE?

What version of android is on the device (including the baseband version, setting>about phone>software info>)

What version of the BTU firmware are you trying to flash? Android 10 or 11..?
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] kevinireland11:
Hey thanks for replying to me :)

it's Sm-G781B

I'll attach a screen shot and you could maybe look over this for me, I type my model number and BTU in that tool "frija" it came up firmware CUD1 I tried to flash that and ot said failed,

I mean iv done these with a number of samsung phones and I'm just wondering am I using the wrong odin or even frija tool, I'm unsure.

Appreciate it.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] afaneh92:
Actually this wont change your CSC to BTU. You need to do it manually.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] b1k3rdude:
Ok so G781B is the Uk snapdragon version. The Android is v11 and firmware I can see is S781BXXU2CUB5, and checking Samobile (https://www.sammobile.com/samsung/galaxy-s20-fe/firmware/SM-G781B/BTU/#SM-G781B) your already on the latest firmware.

So like afaneh92 has said, you just need to change your CSC. Search the forum for the howto and be aware changing your CSC will force as factory reset.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] kevinireland11:
I tried changing the csc by installing the Google dialer and typing in the code but it doesn't work for me, I don't it on my s20 plus a while back and it worked but has stopped working for some reason, is there another way to change csc or just buy the Samkeys?
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] b1k3rdude:
I havent ever done it, but a quick link on this forum showed a hidden menu for the S20 that might work on the FE.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] shouk_1987:
This method stopped since Android 11 February security patch.

Also csc cannot be changed now via Odin in android 11

You need either Samkey or another paid tool ( forgot its name )

I wanted to change csc for call recording as well but managed to bybass via using firefds for android r (u must be rooted and have xposed )

Tried A tried A/B don't know where to flash it there's only the super partition and no system partition because if i flash the super partition bootloop occurs
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
so you select flash ''image'' and it doesn't offer you a system partition to flash to ???

Hello there , I was just wondering if you could share on how you got fastbootd to working as I've been trying on another Samsung for quite a while and it crashes the recovery when I click on reboot recovery.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] afaneh92:
Only devices with dynamic partitions can support fastboot.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
@afaneh92 just checking in to ask what if any sources to you want / need to help you ?

I'm on the Samsung open source site now and downloading a zip for G781BXXU2CUD1 but I've no idea if it's kernel sources inside (280mbs ish). another page I saw here mentioned using the inquiry tab to submit a request.

if you can tell me exactly what you want I'll more than happily put in a request for it, I'm sure others would too.

I'll edit this later and add the zip files full name that I've downloaded and if you want that I'll put it mediafire or similar.

SM-G781B_SEA_RR_Opensource.zip is the archive name, taken from clicking on G781BXXU2CUD1 which matches my current baseband and buildnumber

Is external sd supported yet? Also is there any way to flash twrp without losing data?
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] shouk_1987:
I am now on rooted CUD1 bootloader v2

If i want to install twrp on new CUD6 ( bootloader v3 ) , will i need to do full wipe ?

Cannot it be done while keeping data ?
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] bininga59:
If you flash the Firmware CUD6 with Odin, then your data is gone anyway.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] shouk_1987:
Hold on , why the data would be wiped ?!

I will flash the Home csc like i normally do with incremental updates
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] bininga59:
If you flash a firmware with Odin, then all data is gone.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] shouk_1987:
You didnot tell me a new update

I am always flashing via odin without wiping data using Home csc

So why are you saying that flashing via odin always wipe data ?
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] bininga59:
It will be reinstalled as if you were reloading Windows. All data will be deleted and then the new firmware will be installed.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] shouk_1987:
Still no solid update or a proof from your side

I am saying that i have been doing this for 2 to 3 months with home csc via odin and i have never wiped the data
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] butchieboy:
If you use Csc instead of Home_csc in Odin, data is wiped
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] butchieboy:
Are you talking about just updating Twrp? If so you can update without wipe. I just did this last night
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] afaneh92:

I was asking you as I havent tried. I will go and buy and OTG usb key and test.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] shouk_1987:
Yes i am aware of home csc but this is the 1st time that the FW update i am flashing vis odin is incrementing bootloader version ( from 2 to 3 )

So will it wipe even if using home csc or it won't ?
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] shouk_1987:
@afaneh92

Is it possible to flash twrp without wiping data , meaning keep encryption enabled and without flashing multidisabler and formatting data ?

Many thanks for your support
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] afaneh92:
Yes you can without flashing multidisabler, but you cant use internal storage in twrp.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] shouk_1987:
Then i guess i will gain no benefit then from twrp as i will not able to flash any file or take any backups, right ?
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] afaneh92:
You can use ext sdcard or usb otg
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] b1k3rdude:
I just completed a successful backup and restore via USB otg. see attached. Yes backup and restore to the ExtSD would be preferable, this is better than nothing.

Also I have figure out with file system that can be read/written by trwp and android, as I formatted the 64Gb stick with EXT4 from twrp and when booted back into android it wasn't able to read it.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] shouk_1987:
Ok got your point

And I will be able then to do nandroid backup and restore or flash any zip etc

All via usb otg as an example

Then i will add latest twrp on AP AND home csc then flash only these two via Odin

Then i should be rebooted to system without data being wiped and will have twrp ( without internal storage access )
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] b1k3rdude:
@afaneh92, with the S20FE compared to my S7 there are a bunch more option for backup. Is there a wiki article or a post on here that explains what you need to select and what you dont?

[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] bininga59:
An update does not delete your backup which is on the SD card.

What reliably got it to work was using the vmbeta_disabled_r file from this thread instead of the one linked in the thread :D

you didn't @ him so he'd be notified about the post, more importantly if it's not a TWRP problem it's not his problem.

if you're still trying to boot an android 12 GSI on an android 11 vendor with a TWRP designed for a specific version of our android 11 that's probably where things are going wrong for you.

as I understand it (I could be wrong) TWRP relies on the kernel version we have, an android 12 kernel might screw up TWRP.
