Sorry for replying so late, I didn't receive a 'new post' notification. Have a look at this, the links are there: http://www.howardforums.com/showthread.php/1799038-sharp-102sh-104sh-free-sim-unlock-program

----------------------------------------------------------

Some Russian guys have managed to extract and make installable the Feel UX and the Sharp Lock Screen available on newer Sharps (and the 102SH). Link here: http://4pda.ru/forum/index.php?showtopic=457654&st=0

However, Feel UX will crash when trying to add a widget on y SH-01D (and others), and the lock screen is not available. The solution to this problem is to put both APKs in system/app and change the permissions to rw-r--r-- but I can't do that because I don't have root.

I just tried running the Vietnamese root package. It did do something, the phone rebooted and nothing... Only my pedometer user information was deleted.

EDIT: I used the files I have, not the Vietnamese package, and I now have permanent root - I am running 2.00.04.

However, something isn't right... I can't remount /system as RW. The main directory is RW, weird...

I even installed SetCPU+...

Using ADB from my computer, when I type adb shell I see shell@android:$, then type su, and see shell@android:#. So far so good. But if I try to push a file to /system/app, I see: "error:device not found".

Then I installed this special app that lets you mount system as RW, "Mount /system (rw / ro)". It returns "OK" when I set /system to RW but nothing happens.

So, I tried another one, "Remount", which says "Failure! /system could not be remounted as RW".

I don't seem to be able to change the permissions for /system to RW whatever I do.

Any ideas?

EDIT 2: I've made some progress... not enough though...

Executing some commands under instructions from Japanese websites, I was able to get RW permissions for /system (until reboot). So, I tried to copy two APKs (the Feel UX and the Feel UX lock screen) to /system/app and also to edit the build.prop file changing the "force camera sound" parameter --- the APKs were copied in the folder, and I saw a message that replacing build.prop was successful. But after reboot the APKs were gone, and the build.prop was restored to its original version... No idea...

Here are the instructions:

1. Download "sh01ddump" from here: https://docs.google.com/file/d/0B8LDObFOpzZqNTU5LUlINFFiZlE/edit

2. Execute the following (assuming you've already rooted the phone)

> adb push sh01ddump /data/local/tmp/
> adb shell chmod 755 /data/local/tmp/sh01ddump
> adb shell
$ /dev/xsh
# cd /data/local/tmp
# ./sh01ddump 0
# mount -o rw,remount /system /system

In my case, however, I had to do some changes. I don't have the TMP folder - instead I have this link "tmp -> /sys/kernel/uevent_helper".

So, I decided to push "sh01ddump" to the "tools" folder. Then, when attempting to execute "/dev/xsh" some error is returned, so I just type "su". Thus, the code I execute is as follows:

> adb push sh01ddump /data/local/tools/
> adb shell chmod 755 /data/local/tools/sh01ddump
> adb shell
$ su
# cd /data/local/tools
# ./sh01ddump 0
# mount -o rw,remount /system /system

And I seem to get RW access to /system (see second attached screenshot). But I still can't do the stuff I want to.
