[Xperia Z Original Android Development] [NUT]:
As I've been working on the Stock ROM release of 10.1.1.A.1.307 some of my users started reporting that the issues I fixed for my 10.1.1.A.1.253 release started popping up again: whenever anyone with a locked bootloader tried to remount /system writable (remount,rw) it spontaneously sprung a reboot... very annoying, to say the least! :mad:

It gets even better (or worse, depends on how you look at it) when you consider any CWM version ever released for our Z/ZL models will ask us if we want it to prevent the ROM from flashing STOCK recovery... /system/etc/install-recovery.sh is the culprit here as it is what CWM disables by making it non-executable when you say YES to the question 'ROM may flash stock recovery on boot, fix?'. It actually is an important part of the rooting process we all know. It stopped the RIC service and prevented the reboots from happening. If someone said YES, the issue mentioned in the previous paragraph would also start happening and some users have even reported loss of root and even bootloops because of this... :eek:

I've set out to find a fix for it, one that eliminates the chance a regular run-of-the-mill CWM user will ever encounter the question ever again.

For all of the regular users, download one of these:

Warning for Xperia T [ALL VERSIONS] Users: There is a problem with this patch combined with the CWM package for your phones, it seems to be busybox related. @garik.007 found the solution to this issue: BusyBox by Robert Nediyakalaparambil. Install that app, update your busybox and it will fix CWM and the remount-reboot fix :)

WINDOWS INSTALLER: [NUT]'s definitive remount-reboot fixer!

Make sure you have USB debugging turned ON.

Download the package, save it somewhere you remember

Unzip it somewhere you remember

Run the install.bat file and choose the superuser app you are using.

Done!

The phone should do what the installer tells you it's doing, so

if it says your phone will reboot

, it will. If it did

NOT

explicitly say that it would then something went wrong!

RECOVERY FLASHABLE: [NUT]'s definitive remount-reboot fixer!

This is a flashable ZIP, install using CWM or TWRP and you're done!

It is safe to use on any STOCK (Read: NOT CM Based) ROM version released for all Xperia phones with the ric binary incorporated in the ramdisk (/sbin/ric) up to now. To see if this fix will work for your device, check if the 'ctrlaltdel' command is executed from the init.sony[anything].rc scripts. If it is, this will work!

NOTE: As this fix needs busybox to function and will install or update busybox in /system/xbin if no busybox or no busybox binary which supports the 'nohup' applet was found in /system/bin, /system/xbin or /sbin.

NOTE 2: As soon as you have installed this rootfixer and you saw it replace the already installed busybox, remove any and all busybox installer apps you have, it will probably break the rootfixer if you update busybox using that app. The version this rootfixer installs is rock solid and is used by most if not every kernel dev working on Xperia line kernels.

NOTE 3: If you have an unlocked bootloader, you can actually also install it, it won't hurt and you'll be protected from the reboots if you re-lock your phone!
