[ROM] Stock Jelly Bean, Rooted, Deodexed, Crapware Removed

[tasinofan]

Hi Louis777

Not sure which original brandnew medion JB you mean, but, I started from
http://tapntap.http.internapcdn.net/tapntap/medion/A2110-JB411_02_00_130313_316_WW_F.zip (as sniffed in logcat by vampirefo).
If there is an even newer one please let me now, my tablet says I am up to date.
Now, if you flash that stock zip, be it OTA or CWM, of course, you loose root. And if you reboot your CWM recovery will get overwritten.
Luckily you have CWM, so you can flash unsigned alternatives. I say luckily because original rootmany method no longer works.
You can (as I did) make a ZIP with su and SuperSU added and with recovery overwriting script and stock recovery file renamed.
If no success you can still try as in mcl630 "[HOW TO] Install ClockworkMod Recovery and Root" thread

Thanks

If you can install CWM, you can use it to install root. Does your device have fastboot? If so, the methods should be exactly the same.

@Nighthunter & @mcl630

yes, seems device has fastboot

I never used it to actually erase or flash anything but (using -i 0x0489) I tested things like:

fastboot -i 0x0489 reboot-bootloader
fastboot -i 0x0489 reboot
fastboot -i 0x0489 continue

note that without the foxconn USB vendor ID 0489 you will typically see:

< waiting for device >

Thanks

Then you should be able to flash CWM with:
fastboot -i 0x0489 flash recovery filename.img

Obviously, substitute the file name of the CWM recovery image for your device for filename.img.

Hi,

I will flash the new JB Update feom Medion / Lenovo A2109A aka A2110A.

Here the link:

http://tapntap.http.internapcdn.net/tapntap/medion/A2110-JB411_02_00_130313_316_WW_F.zip

I take a look inside the zip-File. I´m sure, this is the right stock.zip!!

I do this over CWM. Enclosed you see the error.

I think, the Stock.zip must be changed to CWM.zip!! Then I can flash it with CWM.

I don´t know, how to do this.

Any Idea???

Greetings Louis777

Flash Stock.zip over CWM on Lenovo A2109 aka Medion Lenovo S9714

 

[vampirefo.]

open the zip edit update script remove "assert(getprop("ro.product.device") == "S9714" || getprop("ro.product.board") == "A2110");" then rezip and flash.

seeing you have cw recovery, open the zip add root remove recovery files, and remove any apps you don't want then rezip and flash the zip.

@Louis777

Please recall that you will loose root when flashing stock.

You will also loose CWM if you do not remove or rename the recovery overwriting script and the stock recovery file.

Typically I rename

/system/etc/install-recovery.sh to /system/etc/_install-recovery.sh
and
/system/recovery-from-boot.p to /system/_recovery-from-boot.p

You can prerefably do that in the ZIP's update script.

In fact you could, as I did, also change the ZIP to include su and SuperSU.

If all fails, try mcl630 CWM and root methods.

Thanks.

Hi mcl630,

can you take a look on the post after yours ( on sit 11 )

Here is the link:

http://www.androidtablets.net/forum...bean-rooted-deodexed-crapware-removed-11.html

I tried to update the Stock-ROM over CWM. I mean, all ROM´s (Custom or Stock) for the Tablet I can use. This is the Original ROM from 28.03.2013.

May be you can help me. I think, you have more experience about Android and create ROM etc..

What I do wrong?

I´m waiting for your Answer.

Thank´s a lot.

Hi Louis777

The script is META-INF/com/google/android/updater-script

I unpack/pack on Linux. I guess Windows is fine too.

here are some details from inside my extracted update.zip

# 2 files renamed (in the zip not in needed in the script)
$ find -name "_*recovery*"
./recovery/_recovery-from-boot.p
./recovery/etc/_install-recovery.sh

# su busybox and SuperSu included in the zip
$ find -name su
./system/xbin/su
$ find -name busybox
./system/xbin/busybox
$ find -name SuperSu.apk
./system/app/SuperSu.apk

# script adjusted to set u+s for su (make sure su is root.root)
$ grep su META-INF/com/google/android/updater-script
set_perm(0, 0, 06755, "/system/xbin/su");
$ grep busybox META-INF/com/google/android/updater-script
set_perm(0, 0, 0755, "/system/xbin/busybox");

I think that was all I did.

Hi, tasinofan,

you wrote on Page 11:

Then you should be able to flash CWM with:
fastboot -i 0x0489 flash recovery filename.img

I do this with:

fastboot -i 0x17ef flash recovery a2109_CWMrecovery-6.0.1.9d-JB.img

The number "17ef" I got this from Lenovo-Forum. Should be the Lenovo ID-Number.

It work´s - no failure! My CWM I flashed with this Number.

Next:

The new JB-Update Vers. 2.0 from 03.03.2013.

I changed some Items, but the major Failure ist most the same like on my post from Site 11.

After 2 or 3 error´s, I flashed back to Original Lenovo A2109A_A411_03_13_121126_WW.zip.

First time i could´t not start right now. Allways the build in Launcher says: end.

Then anotherone flash - it work´s. Puuh...

O.K. Next flash with the new ROM from March 2013, i do first, when a Developer from A2109 Roms has take a look on the ROM and changed the nessessary Items.

I´m afraid, to brick my Tablet!!!

What do you think? You like not to go bach to the Original ROM?

Let´s find out together a way for this?

Greetings

Louis777

 

[vampirefo.]

the fastboot numbers are based on which boot.img you have installed, if using a2109 boot.img you would use 0x17ef, if using 2110 boot.img you use 0x0489, what do you need help with?

 

[vampirefo.]

Make sure before you install rom, to wipe cache and data, via cw recovery. This rom is rooted, recovery files removed, update script edited.

Hi vampirefo.,

thank's a lot. My Original Medion Lenovo LifeTab S9714 work's again. JB is may be the same like A2109A - but I have my GPS/SIM back.

I couldt not belive, after the first Start - the Tab ask me for the SIM-Pin.

Great - great - great!
