Team Win Recovery Project 3.x, or twrp3 for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.

Code:
 * Your warranty is now void.
* I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, or your getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at me for messing up your device, I will laugh at you.

Supported Models:
Galaxy S20 FE 5G G7810, G781B, G781N, G781U, G781U1, G981W and G780G (4G).

US/Canada bootloader unlock thread:
here

Download & Guide:
1. Unlock your bootloader.
2. Download S20 FE 5G: r8q.
3. Reboot to download mode and flash vbmeta_disabled.tar in AP slot and reboot. Device will reboot to stock recovery mode prompting you to wipe data so wipe data and reboot to download mode again.
4. Put the TWRP tar for your device with Odin in the AP slot and click start.
5. Reboot to recovery via recovery key combo.
6. Disable encryption:
Or:
- Go to Advanced > Terminal, type: multidisabler.​
If vendor complain about free space left on device, will attempt to resize vendor. and it ask to - Run multidisabler again!.​
- Type: multidisabler again. will see - Finished. when done.​
7. Go back to Wipe > Format Data > type yes.
8. Reboot to recovery.
9. Flash magisk apk in twrp.
10. Reboot to system, Enjoy.

Note:
To disable encryption manually:
You need to replace fileencryption=ice with encryptable=ice only in userdata line (maybe rest lines) in vendor/etc/fstab.qcom
To avoid stock recovery restoration manually:
Rename system/recovery-from-boot.p to recovery-from-boot.p.bak

Support:
Live support is available via #twrp on Freenode with your IRC client or just click this link.

Bugs:

Hello ,
Okay I just tried to install twrp. So the installation went well but the concern is that it does not recognize my sd card and therefore cannot access the multidisabler and magik files to continue ....

I also tested by putting everything on a usb key and the same problem .....

You can push them through adb to any place like root / or /data
Also you can use external sd!

Try to copy files to sdcard while you booted to system!
USB OTG will be fixed next build.

Your idea to connect the pc to the phone to seem to work. Twrp recognized the twrp file on my disk and I introduced the 2 files. And there it worked .... Thank you very much for the idea.

Silly question but can I still install OTA updates if I unlock bootloader/flash custom recovery or root the phone? And will stock recovery flash every time I install OTA update?

Thanks in advance

Flashing multidsabler make some changes to system and vendor. So no OTA, Flash full firmware instead.
Is there magisk that we can root? Any guides on it please.
Flash magisk zip in TWRP or patch boot.img using magisk manager and flash via odin.

Hello ,
This update can be installed directly or must first be installed the 1st version. I ask this question given the size difference between the 2. Thank you for your answer .

Yes can be flashed directly, You can see in changelog that we moved to gzip format, that explain the size difference.

    Hi all.

    I have a Galaxy S20 FE 5G SM-G781B/DS.
    Once rooted, is the unlock of apps (like banking apps or other apps) with fingerprint works ?

    Thanks.
    that will depend on the app, if you successfully hide root from your banking app it should work fine. there are a few banking apps that are harder to hide magisk from, they look at more things or the request root access to test the system.
    it's probably quicker to search for the names of your apps plus magisk hide.
    not really the right place for this question.

    make a thread in the questions and answers section or even better in the android general section, then ask if your specific named banking apps work for others if you can't find the info yourself.

    Hello, is the SM-G780G/DS the same as G780G? All I know is that the DS model is Dual Sim, but idk if it's any different.
    Also does rooting delete any data?
    as far as TWRP goes they are the same yes.
    rooting does not wipe data but unlocking the bootloader does and flashing multidisabler (so that twrp isn't overwritten) requires a format of the data partition afterwards.

    @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 buildnumberView attachment 5299763
    I will start working on the new kernel source soon.

    @QRCode please consider making a thread about the exact method it required, resources needed and your experience with it.
    this sort of thing will be useful to others. particularly of interest is the features that don't work currently.
    I'll do my best still testing everything compiling my data etc
