updating a Samsung Galaxy S2 i9100 #39

Main phone went to warranty, old phone is dead, time to revive the museum piece.

So, after turning the phone this was the version installed, which is surprisingly recent:

Installed LineageOS 14.1 20190308-Unofficial-i9100
Base: i9100XMS2
Kernel: 3.0.101

Went to XDA-Developers as usual to see if there are updates and, according to this thread link there is in fact a monthly update for this phone, this phone was release in 2011, amazing!

so files to download:

Place, files into SD card, remove back, remove battery, put SD card into the phone and.. it looses the date, internal real time clock battery must be dead, not sure if having an very old date will cause issues but I decided to set the date prior to installing the ROM.

reboot phone into Recovery:
- Press Volume up + Power/Standby + Home and hold for 10 seconds.
- When Samsung logo appears, release power button.
Phone is installed with TWRP 3.0.1
- set the date, inside TWRP open terminal, type:
date -s 201.04.29-19:30
Format partitions
- Wipe -> Format Data -> Type [yes]
- Wipe -> Advanced Wipe -> Select:
* Davik / ART Cache
* Cache
* System

Install LOS-14.1 + Gapps + addonsu

reboot phone into Recovery
Wipe cache and boot to system

to enable root :
reboot phone into Recovery, install addonsu
After installation go to Settings>Developer Options>Root access and set to Apps only or Apps and ADB
There is no need to install a Root Access manager, LineageOS has its own, you can check what apps have root access under Settings >> Developer Options >> Manage Root Access

Installation done,
skip wireless during installation
install Uptodown app, then install
