Edit: definitely can't flash Pie .tar and .md5 stocks in odin, even the final with bootloader v3 or Q builds. Not looking promising now. Anyone with any idea at all? @mbprtpmnr @KineSight
Really idk, I just blocked my A20e trying to flash A202FXXU3BTG2 firmware... Idk what to do... `An error has occured while updating the device software. Use the Emergency recovery function in the Smart Switch PC software` This is the error... And I can't use Smart Switch because I am on GNU/Linux...

Can you use Odin or Heimdall on Linux? If you can, download and flash the latest stock ROM using them. The screen you've got is just rebadged download mode

Hi, thanks for your guide and sorry for this dumb question:

I have done all the steps and I'm running Lineage 11 GSI. Now I want to root with magisk. Do I have to use the method in the special "Samsung" section of Magisk install guide (here) and lose all my data, or can I just flash with TWRP (changing .apk to .zip and flashing in twrp)?

Thanks!

No need to change any apk to zip just flash Magisk 23.apk in TWRP.

So i currently have replaced my recovery with TWRP, works perfectly except MTP and my sdcard is encrypted, tried multiple passwords, no luck, tried wiping the phone and same thing. Can't drag files to the phone to be flashed. (TWRP shows sdcard's normal size, it's not at 0mb, and does not ask for password when i boot into it. It only displays multiple folders with randomly generated name.)

SM-A202F/DS
A202FXXU3BTK1
Android 10, Security patch level: 1 November 2020

How should i go from here on? How do i disable the encryption and how do i achieve root on this device?

Many thanks!

    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:
    #include <std_disclaimer.h>
    /*
     *
     * We are not responsible for bricked devices, dead SD cards,
     * thermonuclear war, or you 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 us for messing up your device, we will laugh at you.
     *
     */

    I’d recommend to read everything in this post, if you care about your phone.
    1. If you already unlocked your bootloader, start with step 3.
    2. First you need to unlock your bootloader. You can do so by enabling developer settings first, enable oem unlocking, then shut down your phone, hold volume up and down at the same time and while holding them plugin your charger. Your phone now should show a green screen with instructions to unlock the bootloader. Just follow them and after the unlocking your data should get wiped. After that your device will boot up and land in setup screen. Do not setup anything, just skip as much as possible, because your phone will get wiped again. Enable developer settings and make sure oem unlocking is greyed out and enabled. (If it does not show up, connect to a network first!)
    3. Flash Galaxy A20e TWRP.tar via Odin or heimdall
    4. Reboot into TWRP AS SOON AS THE FLASHING PROCESS IS DONE because otherwise TWRP will get replaced with the stock Android recovery
    5. If you want to flash a GSI, skip to step 7
    6. Factory reset in TWRP and reboot to stock
    7. Wipe everything in TWRP excluding SD Card / USB OTG
    8. Put a GSI image file onto an SD Card, alongside GSI_Fix_boot.zip and Disable_Dm-Verity_ForceEncrypt_03.04.2020.zip
    9. Flash the GSI image, flash Disable_Dm-Verity_ForceEncrypt_03.04.2020.zip, flash GSI_Fix_boot.zip, wipe cache and reboot.
    10. Enjoy :)

    Current bugs
    • Encryption/Decryption on stock does not work, you cannot read the internal storage while using the stock firmware
    • ADB and USB connection / USB OTG does not work

    I'm stuck at GSI (PixelExperience) installation. I've extracted the img file on sd card and the wizard is asking which partition should be used to flash image (boot,recovery,product image,system image,vendor image).

    The A202F is an A/B device, despite what Treble Checker apps say. Only A/B GSIs will boot on it, as far as SD Card issues go, I cannot reproduce them, SD Cards work perfectly well in any GSI I've tried.

    Yes
    The a205xx is a fake ab (a plus SAR)
    Glad to hear the GSIs are working for you.
    Any custom ROMs for your device?
    1
    Possibly... Although this guide written in the Q timeframe so... Give it a go if you wish. Btw @KineSight, where are the A20 instructions?
    Custom Vendor for Android 11 has not been created for A20/A20e yet. That's why everyone is still on Android 10 Based Vendor for Android 11 ROMs.

    Since you are on Android 11 and an A20e user, I am not familiar with your issues as I am an A20 user on Android 10 .

    _ _ _

    Not sure if this will help but when you are flashing the Custom ROMs - make sure that you are NOT using the OneUI Vendor.

    IF there is NO 'Vendor.img' in the Custom ROM zip then download the A20 Custom Vendor from here and flash with the Custom ROM when installing in TWRP.
