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.

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:

If vendor complain about free space left on device, will attempt to resize vendor. and it ask to - Run multidisabler again!.​

Hi,
I tried to root, but stopped on the first try: Unable to install "vbmeta_disabled.tar" with Odin 3.14.4. Odin says "failed" and on the phone I got a message "Only official binary are allowed… " on the S20. Before starting I have unlocked the bootloader, I get the warning message when it starts.
Can someone give me a direction to look for ? Many thanks.
PS my device is S20FE 5G, SM-G781B, FRENCH (FTM), G781BXXU4FVC4

Hi,
On my first attempt, I got a strange thing: when I connected my phone to my PC after unlocking bootloader, Odin didn't see the S20 and nothing happened. So I removed the cable, stopped Odin and restart the phone-in download mode, and Odin saw the S20, but it didn't work as I reported in my preceding post.
As I didn't understand, I redid all, re-locked bootloader to be in basic state when I got the s20. And now, all is OK.
I tried to use OTG on a USB key to put vbmeta, multidisabler and Magisk but TWRP didn't see these files, I have to use a PC and transfer files to phone.

I confirm that TWRP doesn't recognize OTG device. I booted in recovery and tested with File Manager: there is a folder called "USB-OTG" but it doesn't see any file in this folder. I tried to connect to the PC, and it is the same. But from the PC I can see the internal storage of the S20.
Any idea ?

Edit1: I tried several USB keys usable by Android (FAT or exFat) and all are the same. Finally, I tried with a small card reader able to directly read a micro SD card and it worked for TWRP backup, but also for reading files to restore. (I didn't make restore test, it's enough for today. )
I think that not all USB storage devices are suitable for TWRP (or to the S20FE), we have to check before making a backup.

    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

    @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
