15. Follow the instructions to unlock vol + to select yes to confirm.

no touchscreen after rooting A20e

Hi Guys,

i tried rooting my SM-202F using Magisk 7.5.1 and Odin 3.14 but whenever i boot into the rooted OS, my touchscreen won´t work.

I tried the following two Builds with the correct language code..

A202FXXU3BTD1

A202FXXU3ASL4

both resulting in a not working touchscreen when booting to rooted OS, when i boot regualar OS without root, the touchscreen works fine.

Any Ideas?
[Samsung Galaxy A20 Guides, News, & Discussion] physwizz:
Did you patch the boot.img
[Samsung Galaxy A20 Guides, News, & Discussion] hannes22:
In my first try, i tried only patching the boot.img with magisk and flashing it but that did not work.

So for the last few rounds i always patched the whole "AP_a202....tar" using magisk which resulted in "successful install" but broken touch functionality.

I opened a new thread to this:

[Samsung Galaxy A20 Guides, News, & Discussion] AOSP100:
I'm planning on getting a OnePlus 7T to replace my SM-A205U, but to make it worth keeping for longer enough I tried to install Lineage on it back in May/early June but no matter what I tried (Odin, Magisk, etc) nothing worked. The constant resets from unbricking the phone loosened the load a little bit but it didn't do enough even after having the Evie launcher since then or any other performance-oriented/lightweight launchers.

There's no OEM unlocking option either

So apparently, even managing to root your phone would trip an e-fuse and brick it at the hardware level. Instead of this all I got were constant errors during the flashing process that force me to flash the factory ROM back and try again
[Samsung Galaxy A20 Guides, News, & Discussion] rwio:
I can't get it to work without getting an unresponsive touch screen after reboot. I've tried the method in this thread to the letter, but no luck. After I've done the rooting and reboot into android the touch screen doesn't work.

The phone I'm using has Android 10 and U3 bootloader...

My bootloader is unlocked (and OEM-unlocking is visible, grayed out).

I'm patching the same firmware the phone had out of the box (I've also tried later/newer versions).

I've tried patching with both latest magisk manager and the canary version.

I've tried both the method in this thread patching only boot.img (boot.tar) and also tried patching the full AP_XXX.tar file as described by topjohnwu on github (it worked fine on the Samsung A10).

But I just keep getting an unresponsive touch screen after rooting. If I revert back to unrooted/unpatched firmware the touch screen works again.

[Samsung Galaxy A20 Guides, News, & Discussion] rwio:
I solved it. First I downloaded and flashed the newest firmware _without_ using a patched Boot.img or AP.tar-file. I.E, patching the same firmware the phone had out of the box did NOT work. After the firmware update I could successfully flash a patched Boot.img file and root the phone. I'm guessing it has something to do with Samsung updating the touch screen drivers since the phone was released.

This is the TWRP and recovery instructions I used. However does the bug indicate that ALL internal storage doesn't work on stock? or just as it applies to Encryption / Decryption. If so I think it needs a better description for others. Will this problem go away if I get a GSI working properly?

I cannot seem to get a GSI installed successfully, I tried several (CrDroid, LOS and AOSP treble) and they all flashed boot icons for hours and never booted.

Many of the tutorials say to use an AB partition GSI but the treble partition check says the SM-A202F/DS isn't an AB partition device.

It says:

For example I have an A205G/DS, with PDA/AP Version A205GUBU2ASG1

In latin america there appears to be a lot of downloads, for like brazil, argentina, mexico, etc. etc...

How do I go about finding the country code for firmware, I bought a random latin america version on amazon
