SGT-OtherOS Gentoo armv7l vfpv3-d16 for GT-7510

Warning!

Do

NOT

attempt to flash this on any other SGT besides the GT-7510. DO NOT FLASH on the 3G and LTE models!

This has not been tested on models with mobile radio, which usually have a different partition map, and more locked down (aka easier to brick) secure bootloader.

You have been warned!

This is not ready for production use. This is an enthusiasts' OS.

Just a note, flashing these partititons (then subsequently wiping /system with mkswap) is not as harmful as it may sound. I have successfully flashed back to Stock with Odin to test this before posting it.

Features:

Based off of TABUNTU Project

OpenRC Gentoo System

CWM v5.5.0.4 recovery for flashing Kernel Updates, or accessing ADB to debug (OtherOS is under /data/ in recovery)

Customized kernel with some driver updates, and all kernel modules (GitHub Source)

Imported pershoot modifications (Overclocking, USB Charging, ect)

Linux Shell (no gui yet)

Custom scripts

Uses /dev/mmcblk0p4 (/system) for compcache swap space

Current Hardware Status:

Basics (Display, NAND, RAM, CPU, yadda yadda)

Full USB and Charging

Battery Status

Wifi support (WEP)

Sound support including jack detection

Touchscreen (with Kernel Update m1-2012.03.24)

Known Issues:

The backlight does not turn off when linux power saving turns on

It is impossible to turn the device off while plugged into a charger (this is due to how the charging animation works. Unfortunately this may never work. /sbin/init on ramdisk is the key/reason)

Pressing CAPS-LOCK (or any other led-lighting key) on USB keyboard will kernel panic.

Kernel Updates:

m1-2012-03-24

Patched touchscreen driver to be evdev and tslib compatible

Anything not listed assumed not working

How to install

WARNING!

You will lose

ALL CURRENT DATA

stored on your tab,

including /sdcard

! I did not brick my tab doing this, but cannot guarantee anything for you. Try this as your own risk!

Each time you flash the kernel for OtherOS, your "Custom Binary" "Flash Count" flag in Odin increases. AFAIK, this just means your warranty is VOID, and has no ill effects on the tablet.

This is not dual boot and REPLACES Android, but it is easy to revert back. However, there will be no Android OS while OtherOS is installed!

Download SGT_OtherOS_Gentoo_m1.tar.7z

Flash via Odin

Root password is gentoo, change it.

The image has an auto-resizer, so when you flash data.img, it will auto-resize on first boot, and give you a 13gb partition for your OtherOS.

How to Restore Android

When you restore to Android via Odin, it leaves /data un-formatted. Because of this, there are a few extra steps to restore back Android completely.

Download p4_16G_32G.pit and an Odin stock dump of UEKMP

Flash them as you normally would to restore to stock.

Wait for reboot, you will get an error in the stock recovery app

When the menu appears, choose Wipe data/cache

Reboot and choose one of:

A. To go back to stock: Reflash the Odin tar without the .pit file this time

B. To go back to custom: Reflash CWM and either restore nandroid, or format /system and install a custom ROM.
