@Agrim720
I would appreciate your help with my problem.
I upgraded from U2 to U4 and started using your TWRP.
Everything seemed to work well but now I get stuck on the boot logo when I restore my backups.
Please help

Click to collapse

Finally managed to develop a hybrid backup and restore technique.
I use TWRP for boot and data
I use TWRP file manager for system apps.

I don't understand this step... I need the VBMETA for

Galaxy A20e | SM-A202FZKDDB

WHERE CAN I FIND THIS PROPER VBMETA ???
And do I really need it actually? Please finally explain someone.
I had alot of Problems because of using the wrong VBMETA, be really careful - better not use it at all!

    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 Recovery
 * before flashing it! YOU are choosing to make these modifications
 * If you point the finger at me for messing your device. i will laugh at you

    Special Notes:*
    1. DON'T FORGET TO ENABLE "OEM UNLOCK" (located in Developers options).
    2. KNOX will be tripped once you flashed custom binaries to your phone.*
    (Your warranty may be voided. However this may not affect you if your country forces Samsung to provide hardware warranty regardless of software status.)
    3. Samsung Firmware OTA (aka System Updates) will no longer work once you flashed custom binaries.
    (You can flash custom ROMs if you want to keep the OS up-to-date.)
    4. All apps that use KNOX like Samsung pay, Secure Folder and maybe more will no more work.
    If you like my work please hit the "Thanks" button and feel free to donate to me via my Paypal

    Quick Root and TWRP.

    A quick method is found here.https://forum.xda-developers.com/galaxy-a20/how-to/guide-quick-root-twrp-galaxy-a20-t4069423

    Make sure you backup boot, data & system (not system image) before you go on to install GSIs

    This TWRP was originally designed for Android 9 but works perfectly with Android 10.
    It also comes with MTP built-in.
