》Can test (temporary install) with DSU Sideloader [A11]

》Can install with Fastboot of TWRP [A11]

》Can install with Odin [A11, A12] [ CustomAP]

✓This GSI is not suported exFAT.

✓Out of the box not able to connect internet. ( SM-T22x) not able to used adb.

But this bug fixed by...

connect to adb

On "secure", USB Debugging has to be toggled on each reboot.

connect to internet

adb shell settings put global restricted_networking_mode 0

There is no Navigation key or gesture options.

try adding "qemu.hw.mainkeys=0" to /system/build.prop.

These images are EXT4 unshared blocks, so as long you have verity disabled and root, you should be able to edit/save it.

Howto install TWRP For SM-T225

# Patch Samsung AP Firmware via Magisk v24.0

1. Install Magisk.apk on your device SM-T225 with select no update checking, and transferred AP_xxx.tar.md5 from computer to your tab.

2. Patch Samsung AP Firmware via Magisk Manager.

( Once done, the newly created magisk_patched.tar file will be present under the

Downloads folder on your device.)

3. you may now transfer this patched TAR file to the folder on your PC where other extracted firmware files (AP, BL, CP, CSC, and HOME_CSC) are present.

4. FLASH it with ODin as usual by used magisk_patched.tar file at AP slot .

5. REBOOT SYSTEM Quick SETUP < NO NEED INTERNET>

6. Power Off and press Volum up +Volumn down + USB for boot into Download mode

7. FLASH TWRP.tar from https://github.com/DevZillion/android_device_samsung_gta7lite/releases at "AP slot"

But this time set Odin option NO Auto- REBOOT, yes do it yourself with key press ( power + volumn up). If you can't do this , let it reboot to system and uses cmd " adb reboot recovery".

When access to twrp

Go to Advanced > Terminal and type "multidisabler" (without quotes", then data wipe.

Now reboot into system, after completing first setup of the device reboot into TWRP again to see if you can see the contents of your Internal Storage, you should, if yes you have successfully disabled Samsung encryption of internal storage.

-install TWRP ( not for the first time installation )

From my tutorial: Easy & Quick RESTORE FROM (ANY GSI ) BACK TO (STOCK with TWRP)

!!! Download the actual Firmware A11 with Frija or samfirm or Bifrost, and extract

it and you will get 5 files (AP, BL, CP, CSC and HOME_CSC). All files are in tar format and can be opened by 7-Zip, WinRAR or other archrive software.

1. Flash the FW A11

- BL + AP + CP + CSC ( clean data)

- put (TWRP + vbmeta_disabler)dot tar in USERDATA slot.

and click "Start"

NOTE.

• Default Auto reboot to system.

• Your device will reboot but it will not boot into system as "vbmeta signature" has changed.

2. When Auto Boot into TWRP mode from step 1.

( May be Black screen , try to press power button + Volumn for activated twrp screen.)

In your TWRP Recovery menu.

• Go to Advanced > Terminal, type: multidisabler. Click Enter.

• Go back to Main menu , Wipe > Format Data > type yes.

Option<<<Install the Magisk.apk with TWRP >>>

3. Boot---->System

Done

NOTE: If you wish to install TWRP without rooting, there are numerous pitfalls to consider. For example, a stock device is protected by Android Verified Boot. This is implemented as a vbmeta partition that contains cryptographic digests for verifying the integrity of boot.img, recovery.img and other partitions/images. Flashing TWRP without first flashing a vbmeta image with verity disabled will render your device unable to boot.

Download:

(TWRP225 + vbmeta_disabler).tar https://mega.nz/file/QTIWmTJb#jIneu-vSC-tOSzN-mFhOurCtShGuZTkyoRrQ791R24s

twrp 220 + vbmeta_disabler :https://mega.nz/file/BTR1FbDL#oMfBn7TQCy2j0Qk3EtIOafoD2IY01AsX8UIOR-mSSVc

》》From your Computer

1. INSTALL "Android Bootloader interface" Driver.

Note: very important bootloader driver for used fastboot of the twrp.

Android Bootloader Interface Drivers are needed for your PC to identify the device connected in Fastboot Mode and hence execute the desired Fastboot Commands.

win10 :

File on MEGA

2. Copy & paste "Platform tools" to C:/ and copy &paste GSI.img into this folder.

( "vbmeta.img" IF NOT FOUNDED , PLEASE EXTRACTED FROM YOUR AP FILE)

Download Platform Tools for Android SDK Manager
