---++ Hacking the Yarvik / Sweex TAB250 ---+++ Hardware The Yarvik / Sweex TAB250 is built using the following ICs: $ TCC8902: Telechips 8902 !SoC CPU / GPU / etc. $ 2x Samsung !K4T1G164QF-BCE7: 1Gbit DDR2 memory $ Hynix !H27UBG8T2ATR: 4GB NAND flash memory $ Realtek !ALC5621: Audio codec IC $ Focaltech !FT5406EE8: Touchpad controller $ AXP192: Enhanced single Cell Li-Battery and Power System Management IC $ Realtek !RTL8188CUS: IEEE 802.11b/g/n 1T1R WLAN Controller with USB2.0 Interface ---+++ Connecting the TAB250 to your PC To be able to log in to the TAB250 as root, you need to connect the tablet to a Windows computer, with the Android platform tools installed (ADB) and the USB drivers for the Telechips TCC8902. The USB drivers can be found by Googling for usb_inf_X5A.zip. After starting *adb shell*, a shell is opened on the tablet, running as user root. Starting a shell using Terminal Emulator (or another app) will not run as root, but as a user with limited privileges. ---+++ Installing ClockworkMod Recovery 5 PLEASE NOTE: This procdure may brick or otherwise damage your tablet and make it unusable (but a nice coaster). To be able to recover your device after flashing a new ROM, you should first install a different recovery image. The recovery image can be used to create a backup or restore a working ROM, or copy files to / from your computer. First, create a backup of the original recovery image, by downloading http://files.androtab.info/telechips/dump-recovery/dump-recovery-signed.zip, rename it to update.zip and copying it to your sd-card. Reboot into the standard recovery image, by holding Volume-+ and the power button for a number of seconds. Pressing the Home button should then show the recovery options. Install update.zip via the menu options. This should create 2 files on the sd-card: dumped_recovery.img and dumped_proc_mtd.txt. Download the ClockworkMod Recovery 5 for the Storage Options Scroll 7" capacitive device from http://androtab.info/telechips/cyanogenmod/, rename it to update.zip and install using the recovery menu. See http://androtab.info/telechips/cyanogenmod/ for more information. ---+++ Creating a backup using ClockworkMod Recovery 5 Boot into the recovery image and create a backup of the default ROM, using the menu options. Copy all backup-files on the sd-card to a safe place. -- %USERSIG{IvoVanGeel - 03 Nov 2011}%
