Installer Odin ainsi que les drivers USB Samsung

Télécharger TWRP, GApps et LineageOS 21.0 UNOFFICIAL.

Pour LineageOS 18, flasher ce script Vendor en premier : repartition script https://www.mediafire.com/file/nx5q6p8qywp1zkw/Exynos7870_CreateVendor_2.0.zip/file05. Sans cela, l’installation de la ROM et GApps ne fonctionneront pas.

FLASH TWRP

1. Preparing Odin

Install USB drivers on the PC, run the Odin program and connect the tablet. You should see the “added!!!” message. Press the AP button and choose the “twrp-3.7.0_9-0.tar” file.

2. Disable “Auto Reboot”

In the “Options” section in Odin, remove the checkmark from “Auto Reboot”.

3. Start Flashing the Recovery and enter TWRP

Press “Start” and wait for the green “PASS!” message. L’appareil va rebooter, très rapidement, il faudra maintenir (Volume Up + Home + Power) pour entrer dans TWRP. Sinon, le système reprendra le Recovery d’origine.

FLASH GAPPS / ROM

1. Advanced Wipe

In TWRP, choose Wipe > Advanced Wipe, and select all options except SD Card, USB OTG, and Internal Storage.

2. Flash the ROM

Transfer the ROM file ROM.zip and the GApps.zip file (this file is optional depending on your need for Google services on the ROM) from the PC to the tablet. Il est important d’installer les GApps en même temps que la ROM, sinon cela causera des crashs. In TWRP, choose Install, select the ROM .zip file, then use Add more Zips to add the GApps file, then swipe to confirm the flashing and wait for the process to complete, then click reboot system.
