The long wait has finally come to an end, as I successfully compiled CWM Touch Recovery for Medion Lifetab P9514. It works great on IceCreamSandwitch 4.0.3 Release 2 and it should also work on previous ICS updates. However, it is not compatible with Honeycomb 3.2!
Before we begin a warning is in order: You are making changes to your tablet’s software at your own risk!
So let's start. I advise you to first backup your stock recovery, just in case something goes wrong. There are couple of methods to do this. I will describe in my opinion the easiest, with adb commands for Microsoft Windows or Linux OS. This way you are not required to boot your tablet in special modes (fastboot or APX).
- When you connect LIFETAB to your PC, drivers should be installed automatically in Windows Vista/7. If they are not or if you encounter any erros, try the guide for Windows XP (original guide by @Pummelchen - android-hilfe.de).
- Download drivers for WinXP: http://www.medion.com/au/service/_li....php?did=10725
- Extract the drivers - double click on "usb_p9514wxp.exe"
- "Medion" folder will be created on C:/ drive, in there you will see "android_winusb.inf".
- Open Device Manager: either by following the path "Start/Control Panel/System/Advanced System Settings/Hardware/Device Manager" or by right-clicking on "Computer" - "Properties" in start menu.
- Connect your LIFETAB with a microUSB/USB Cable to the PC an wait for a few seconds.
- In Device Manager "Other devices" should appear, there you will see "MTP" with a yellow exclamation mark. Right-click on it and choose "Properties".
- Under "Driver tab" choose "Update driver".
- Browse to C:/Medion and start the installation.
- ADB/Fastboot tool for windows (USB drivers included): http://www.mediafire.com/download/bk...B_Fastboot.zip
- You can install adb tools in Linux by following this guide: http://forum.xda-developers.com/show....php?t=2431956
- Make sure you have USB-debugging enabled on your tablet (Settings – Developer options – USB debugging)
- Run Windows Command Prompt (Start Menu – Run… – write in “cmd” – press OK); point the cursor to the ADB folder by using “cd” command (a simpler way: press SHIFT and right-click on ADB folder, choose "Open this folder in command window")
- Open Terminal in Linux
BACKUP STOCK RECOVERY
See if your device is recognized (a long number)
mount -o rw,remount /system
mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.backup
mv /system/recovery-from-boot.p recovery-from-boot.p.backup
dd if=/dev/block/mmcblk0p1 of=/sdcard/download/original-recovery-p9514.img
RESTORE STOCK RECOVERY
Should you at any time encounter problems with cwm touch, or you simply don't like it, you can restore your stock recovery. The commands are therefore reversed:
Restore 1st file
mv /system/etc/install-recovery.sh.backup /system/etc/install-recovery.sh
mv /system/recovery-from-boot.p.backup /system/recovery-from-boot.p
dd if=/sdcard/download/original-recovery-p9514.img of=/dev/block/mmcblk0p1
An easier way to have stock recovery back is to simply re-flash ROM update zip file. But by doing this you will loose root privileges, configuration and possibly user data.
I suggest you save "original-recovery-p9514.img" also to your external sdcard and possibly to your PC. You can use your USB connection cable or a file explorer (like ES File Manager) to transfer the file to an external data storage. Another option is this adb command:
adb pull /sdcard/download/original-recovery-p9514.img
FLASH CWM TOUCH RECOVERY
Now that you’ve successfully backed-up our stock recovery, let’s flash the new cwm touch. Again there are a couple of ways to do this, I will describe in my opinion the easiest.
First download attached file, extract it and copy cwm-recovery-p9514.img to your internal sdcard. You can simply use a USB connection cable and transfer the file to the path “/sdcard/download” or use a file explorer (like ES File Manager) to copy the file.
Another method is with ADB commands. Put cwm-recovery-p9514.img in ADB folder on your PC. Open windows command window and check that your tablet is recognized (adb devices). The following line will transfer the .img file to “download” folder (you can use any other name, but the folder needs to exist on your sdcard):
adb push cwm-recovery-p9514.img /sdcard/download
adb shell su mount -o rw,remount /system dd if=/sdcard/download/cwm-recovery-p9514.img of=/dev/block/mmcblk0p1
INSTALL CWM TOUCH RECOVERY USING TERMINAL EMULATOR
This is a simpler and faster way to flash my cwm touch recovery, without needing a PC/Laptop.
- Install one of free terminal emulators from Google Play Store.
Here are a couple of options:
- Providing you already copied "cwm-recovery-p9514.img" to your tablet, skip this step. If not, look at the previous steps.
- Open the terminal emulator app and insert these lines:
su mount -o rw,remount /system dd if=/sdcard/download/cwm-recovery-p9514.img of=/dev/block/mmcblk0p1
- To restore your original recovery:
su mount -o rw,remount /system dd if=/sdcard/download/original-recovery-p9514.img of=/dev/block/mmcblk0p1
USING CWM TOUCH RECOVERY
To enter cwm recovery mode press hard buttons in combination: power off your tablet, press and hold VOLUME UP (PLUS) and press POWER. Once you see "Ota…" in the top left corner of the display, quickly press:
1X VOLUME DOWN (MINUS),
2X VOLUME UP (PLUS),
1X VOLUME DOWN (MINUS).
You will see the counter go to 4 and cwm recovery will start.
For a more practical access to the recovery, use this app: Quick Reboot.
Make a backup of your rom as soon as possible, to save your data.
Please do not attempt to flash any zip files using this recovery. You may damage your tablet in doing so.
"Wipe cache partition", "wipe dalvik cache" and "fix permissions" are safe processes, but use "wipe data/factory reset" only when needed.
NOTE: I will leave older versions of cwm touch recovery available, should you have any problems with newer ones.
This guide wouldn't be possible, without the help from guys on http://www.avi-plus.com, Yves & Micky.
