[Galaxy S II Q&A, Help & Troubleshooting] toy_story:
Hi, could not write earlier, there was a problem with the Internet, now everything is "okay".

1. Download to your PC, and then copy these files to your phone on an external SD card:

Files for installing TWRP:

- TWRP.3.1.0-0-recovery- the.gangster-IsoRec-i9100.zip

- kernel-Lanchon-20160406-i9100.zip

Files for installing ROM Los 14.1:

- ROM Los 14.1

- Gapps (recommended pico)

To do this, remove the SDcard from the phone, insert it into the PC and transfer the files to the SDcard.

Or put it into CWM recovery mode and connect to a PC.

Management in CWM-based Recovery v6.0.5.1:

Go to the points - by pressing the volume keys. Up +, down -.

Selecting a specific item is the on / off button of the phone.

Select "Go Back" - go back to the previous menu.

In CWM-based Recovery v6.0.5.1, select "- mounts and storage", then "- mount USB storage".

The PC will detect your phone and you will copy the files to the SDcard.

After copying is complete, click "- Unmount", then "-Go Back"

If you already have these files on the SDcard, go to step 2.

2. Installation in TWRP.

In the main menu of CWM-based Recovery v6.0.5.1, select "- install zip", then "- choose zip from / storage / sdcard1", then select the file "- TWRP.3.1.0-0-recovery- the.gangster- IsoRec- i9100.zip ", then

"- Yes - TWRP.3.1.0-0-recovery- the.gangster-IsoRec-i9100.zip".

The TWRP installation process will start, it should be written "Install from sdcard complete". So everything went fine.

Again, choose "- choose zip from / storage / sdcard1", then select the file "- kernel-Lanchon-20160406 -i9100.zip", then click "- Yes - kernel-Lanchon-20160406 -i9100.zip".

The installation of "Lanchon TRIM Kernel" will start and should be written "Install from sdcard complete". So everything went fine.

Now we return to the main CWM menu, for this we press "- Go Back".

To enter recovery TWRP, select "- advanced", then "- reboot recovery", then "- No".

The phone will reboot and go into TWRP.

3. Configuring TWRP.

Put a tick in the "Never show this screen during boot again" and make a right to the right where it says "Swipe to Allow Modifications".

The main menu "TWRP 3.1.0-0" opens, select "Settings" in it and uncheck "Prompt to install TWRP app if not installed". Return to the main menu by clicking on the bottom in the middle of the touch button "Home".

We select "Wipe", then "Advanced Wipe", mark with the top 5 items - "Dalvik / ART Cache", "Cache", "System", "Data", Internal-Storage "and do" Swipe to Wipe "

* Return to the main menu by clicking on the bottom in the middle of the touch button "Home".

4. Installing Los 14.1 and Gapps.

In the menu "TWRP" select "Install", then click "Select Storage" on the lower left, mark "External-Storage" and click "OK".

Select the file Los 14.1 ROM and do "Swipe to confirm Flash"

Installation of the Los ROM will start, after a successful installation, go back and do the installation of "OpenGapps" exactly as well.

After the successful installation of "Gapps", click on the left "Wipe cache / dalvik", then "Swipe to Wipe" and click on the right "Reboot System".

That's all!

But be patient, the first installation can take 30 minutes.

Connect the charger, and have a cup of coffee.
