*****I am not responsible for anything you do to your device. Do this at own risk***** If all goes bad just flash Factory firmware with PIT file.

Credit goes to those who built twrp.img and the vbmeta image for the A30/A70. I am no dev, I read somewhere about the crossflash to DS firmware but cannot find it any more.

This is for people who understand Odin and have some experience flashing firmware.
Maybe someone will make noob friendly instructions, please feel free.

I currently have an a205u with an unlocked bootloader root and twrp.

1. Using Patched odin crossflash to DS firmware. OEM toggle-download mode-unlock bootloader.

2. You are now able to flash back to the W/U firmware keeping an unlocked Bootloader even though you will not see an oem toggle in developer options

3. Patch boot with magisk 8.02 compress it to tar file along with A30 vbmeta.
***** Important***** make sure to use 7zZ for all steps, and rename boot from magisk_patched_image to boot.img or you will receive errors.
( I may have used a70 vbmeta as I was trying various ideas someone will have to try this and let us know) It will hang at samsung logo for a while on first boot.

4. Then flash A30 TWRP using flashify. Probably works with odin too. Boot to recovery- Perform format data, reboot recovery, flash dmverity+magisk. May be able to get it to work in less steps that's just what I did to make it work.

First time flashing I got a pass in Odin and fail on phone Flash the second time everything was good

Sir:

I do not wish to debate you/this method. I very much need to unlock this bootloader (Galaxy A205U w/ And.10). I have run into so much controversy about being able to unlock the bootloader on this particular model; controversy even within this site??? [please see;

I'm not desperate (yet) but very much need confirmation that if I apply this operation, the bootloader will be unlocked. If interested, I have a few more questions about this particular model and what I can/cannot do with it. Please reply Thank You

I have an a205u I was messing around with it flashing various files and somehow managed to have an unlocked bootloader. I can provide proof. But we have been unable to replicate this and I do not have another a205u to try it on. I had found some website that instructed me to use a drk Verity oem lock on repair file. Then was able to flash firmware from another country that provides me with the OEM unlock and ability to unlock the bootloader. then flashed back to the w version (canada) and now have this a205w bootloader unlocked device. I'm willing to help in any way we have tried various things with people online but nothing has worked so far. I'm certain if I could get my hands on another a205u, I could eventually replicate it.

Sir: you replied "I currently have an a205u with an unlocked bootloader root and twrp". Everywhere on this site claims you cannot unlock the bootloader on this model(???). I would appreciate a much more detailed (step-by-step ...if you please) account of how you accomplished the unlocked bootloader. TY (Galaxy SM-A205U)

If I could, I would I have given all the info I could remember. After I did this I broke the screen and it sat for a few months. I had no idea I was the first, I followed directions from some site. When flashing this drk OEM lock on repair file, I was also formating data in stock recovery with system mounted. If I could get my hands on another a205w I'm sure I could replicate it......

Well, had all my troubles w/ Galaxy A205U solved....dropped the damn thing and it trashed the the phone. HOORAY!!! No more Samsung B.S. I'll never own another Samsung product! So, naturally, I'm dropping out of this thread. Good luck to all who need this thread to help solve (hopefully) your difficulties w/ the Galaxy A205U

    You have the only A205U in existence that is rooted.
    Congratulations

    Could you please change the title to A205U so others can find it
