" Custom AP for install GSI without TWRP Step by Step with "imjtool"( no lpunpack ) Credits to @abg95a​

UBUNTU ON WIN10 SUB-SYSTEM. only explain it by an easy way. Nothing new from abg95a post.

✓ When you set Smallest-width = 609 (Developer options)

You made it , not rely on someone. Only Win10 .Ubuntu Sub_system & Odin.

Make it yourself , not rely on Fastboot , Custom Recovery, dd , root .

✓✓Download: Step By Step create CustomAP file ( jpg Format) from Attach file.

✓✓PHH TREBLE SETTING:-

Samsung feature:

Use alternative audio policy

Enable extended brightness range

Enable double tap to wake

Enable extra sensors ( proximeter sencer for LTE version)

Enable workaround for white-ish screen

Misc features:

Use alternate way to detect headset. ( test with sony wh1000xm4)

Disable audio effect (disable AudioFX app of GSI and uses Dolby ATMOST instead.)

Use linear screen brightness slider (if your screen flashing)

Force-disable A2DP offload. ( Bluetooth problem fix )

Special Features on this CherishOS 3.9.5 GSI ( not founded in another GSI ,except SuperiorOS GSI )​

- MTP working on Android 12 base. (set default USB configuration = file transfer @ Developer options)

- Offline power charging.

( corrected "Set Warranty bit" break state . ) when powered off, plugging in the charger would make the tablet enter a screen with text `Set Warranty bit', that you couldn't easily get out of by pressing POWER button alone.

Fix ✓ can turnoff device , charging like normal , warning text "set warranty bit" will turn off and uses POWER button turn on tablet normally.

- Auto Brightness (option) -download my Overlay Magisk Module

( if bootloop was happened, uses ' adb wait-for-device shell magisk...' technic)

- eXFat sd-card supported

Quicker than on A11.

-Trick to add shotcut from Drawer

( -Fixed✓ in the launcher dragging apps from drawer to homescreen

doesn't always work. )

- PHH Fixed✓ Bluetooth & headphone, ✓proximeter for phone, etc.,

Howto install​

You can try with my Custom AP here: 3.4 GB ( Muti CSC zone OLM )​

✓ if you are on Samsung SM-T225 zone CSC OLM , please insert sim before fashing.

( made from CherishOS_v415-arm64-bgS-slim-lite-secure_20220816.img.xz )

✓No root (superuser). ✓No Google assistant

✓ Before your flashing new system , make sure you are already on Android 12 Stock ROM. Bootloader fully unlocked and Enable usb debugging.

✓ After Finishing Flash with ODin , you must select "factory reset" from Recovery Menu Pop up.

( I didn't do magisk-patch new Custom AP file. But create magisk-patch only boot.img.lz4 + vbmeta.img.lz4 separately for flash with odin Userdata slot.)

-another zone: you must make it by yourself with your right zone firmware , cause file size would suffer for upload if you requests me doing.

RECOMMEND: Use Magisk if nesessary .

How? extrack Stock AP file for "boot.img.lz4 + vbmeta.img.lz4" create Archive xxxx.tar ( Pack both as a single tar file with 7-zip) and patch with Magisk.

How? install root

flash magisk patch file from step above in USERDATA slot of ODin
