[Acer Iconia A700 and A510] Moscow Desire:
For A701 users only running Jelly Bean Only.

Boot image used: AV051_A701_1.021.00_WW_GEN1. Should work fine on other JB builds.

New Version 3 uploaded 23/10/2012

Should fix ADB commands for /System Remount Thanks Vorbeth

2 Parts. Part 2 is full /system RW.... also know as ROOT for the A701 on JB who took the OTA

Part 1 is For people using the previous "andlommy" image flash..... For JB OTA see part 2...

Part 1

This is meant to replace your boot.img after performing the Root image flash from this thread by andlommy;

Ok people, as some may realize, the current "root" procedure of fastbooting images doesn't allow full /system remount. This can be seen if you try to update your superuser binary. Superuser can't remount /system. Yes, you can probably delete some files via file manager, however, if you use a root app that calls for a /system remount, well, it's not going to happen. Not like it should be.

Also, the 701 doesn't have a reliable CWM, so we do things the old fashioned (and safer) way.

This method has been around in the 500 forums for some time now. Recently, I gave info to the 210 users to get the /system remount working on their tabs. I currently use the same. Why nobody tried it here, well.....

Basically it involves modifying the zimage to change security, and allow remounts. It does not involve the kernel itself, as it remains stock.

Replaces Stock A701 Boot.img

1. Allows for full /System RW

2. Increased IO over stock.

And yes, I do use the modified boot image, 2nd revision.

As always, you have to thank people who helped you in the past and present:And I owe a lot to these guys. (which is why I hit the Donate button for them)

NOTE" You must have unlocked bootloader"

Also, you do this at your own risk.Most of you know this already.

Installation:

For previous somewhat Rooted JB installations.

Download the following package and unzip to your system.

FIX-JB-ROOT

1. Connect your tablet

2. USB Debugging is on

3. Open a command window where you unzipped the Fix-JB-Root

4. Type: adb reboot bootloader

after tab reboots to bootloader download, Type;

5. fastboot flash boot JB_701V3_boot.img

6. After success, reboot tablet.

7. Start Superuser and update binaries.

Part 2

AS A ROOT PROCESS. 701 only After OTA to JB.

Note that this is an alternative to the image flash method. You need only to OTA to JB, then follow the instructions.....

Needs Testing on a Stock JB 701 Make sure you've unlocked your bootloader

1. Follow the above procedures in part 1

2. After restart, with tab connected, open a CMD Window where you unzipped the package.

3. Type the following commands;

a. adb devices (and hit Enter. You should see your device listed)

b. adb remount /system (and hit Enter. You should see remount successful)

c. adb push su /system/xbin

d. adb shell chmod 6755 /system/xbin/su

e. Get Superuser and Busybox from the Playstore. Start Superuser, check for updating binaries. Install Busybox.

Hopefully this roots and grants /system RW. I don't have a stock 701JB, so would appreciate feedback if this works or not.
