Full GSIs Processing with SM-T225
(From Up to Down)
FROM A11 through A14​

New fastbootD ( Full Tutorial Here )
Flash Firmware and Customed Files. (Firmware +Root + FastbootD)​
>Obtain the official firmware. https://samfw.com/
>Download & Extract it and you will get 5 files (AP, BL, CP, CSC and HOME_CSC)
>Open Odin on your computer and reboot your device to DOWNLOAD mode ( turn-off device , press and hold Vol+ together with Vol- then insert USB cable which one end connected with computer to device.)
>Put AP, BL, CP, and CSC files in their Odin slots.
* Home_CSC for advanced user only.
** Do not changes input fileName for shot.
>Put 3in1.tar
( patch boot + vbmeta + patched-recovery ) in UserData slot.
>Click "Start" and wait for it to finish.
( No interruption)
( From now on Magisk & FastBootD recovery will remain in your device.)

Note: vbmeta.img was patched by Magisk the same as with fastboot command .
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img

flash-FM+3in1.PNG



�
Use FastbootD flash GSI image.​
>*Based Firmware should be Official only.
>*Download & extract Platform-tools to C:/ https://developer.android.com/studio/releases/platform-tools
>*Download GSIs images.
>Open device and connect USB cable to Computer.
>Run CMD within Platform-tools Folder.
Code: 
 adb devices
> adb reboot fastboot
> fastboot erase system
> fastboot flash system gsi_name.img
NOTE: gsi_name.img. must changed to actual name of your extract download GSI from the Sources.
> fastboot reboot recovery
​
* Select wipe data / factory reset
reboot system
Troubles Shooting​
Not enough space to resize partition solution.
> fastboot erase product
> fastboot resize-logical-partition product 0x0
> fastboot getvar all
^Find this (bootloader) partition-size:product:0x0



Make System Writable ( need more details)​
> *Get rid of SU from bvS, bgS GSI Variant.
> *Execute phh-securize.sh
> *Enable pre-install Magisk
> *Install Root file Manager. Mixplorer from XDA here
> We will dump device super-partition and patch it with script.
*Install & Execute Read2Write script.
> Get New super.patch.bin. (output of script )
> Compress super.patch.bin to super.img.lz4
( lz4 -B6 --content-size super.bin super.img.lz4 )
***Don't use fastboot flash super super.img with FastbootD.>>>This will brick you device.



This is old way to install GSI.​

Make CustomAP
from
New super.img.lz4​
> Create New CustomAP tar md5 for Odin. ( with new patched super.img )
Download Clean (blank) vbmeta.img from Google
>Compress the clean vmbeta.img
lz4 -B6 --content-size vbmeta.img vbmeta.img.lz4
>Down& Extract "tar-md5-script-tool.zip" to C;\
mega.nz

2.26 MB file on MEGA

mega.nz mega.nz
>extract all *.img.lz4 files (from AP Stock) to. C:/ tar-md5-script-tool folder
>Replace super.img.lz4 and vbmeta.img.lz4
|
in tar-md5-script-tool dir
|
with your new repacked and compressed
>Run Win Batch File For Packing Custom AP file
> Flash Firmware together with CustomAP
BL slot = BL fie from Firmware.
AP slot = CustomAP file from my Download.
CP slot = CP fie from Firmware.
CSC slot = CSC fie from Firmware. not Home_CSC
UserData = 3in1 patch.tar
** Do not flash CustomAP Alone. (Safety First )
** Do not flash super partition with FastbootD.


Note:
>My CustomAP.tar.md5 for T225XXU1CWA2. (A13) only

Make Writable System and more spaces 500 Mb extra.

    Yeah, if I flash the stock ROM with Odin (AP, BL, CSC) and just leave out the 3in1.tar for UserData everything works as expected and device is usable!

    I actually missed the part about downgrading. If I get the patience to try again I'll give that a go.

    Hi, I managed to root my device, unlock the bootloader, install the custom recovery and all went well.
    I then installed lineageos using DSU and it booted and everything has worked perfectly. Would it now be safe to install it as my main OS?
