Never is a big word

I know, but I think its better then giving false hope. Unless the stock kernels allow kexec'ing a new kernel, there shouldn't be a way.
CM only describes the unlock way, but since many (at least me) am used to just flash CM from CWM, I investigated if and why this wasn't possible.

Is it technically possible to soft brick with this recovery or does it deny flashing wrong kernels? Because that is something I'd put as a warning.

It is, and it is up to the user to try something that risky. I'm not responsible for their misunderstanding the whole concept behind flashing STOCK and CUSTOM kernels and that in relation to the locked or unlocked bootloader requirements...

If you start rooting and modifying your device's ROM (whatever that device might be) you risk bricking it or creating a nice bootloop, it comes with the territory. I'm not the one who should warn users of the dangers ... @DooMLoRD already did with this thread and if people jump in and modify their device before reading up on all the risks and stuff... well... lets just say those people are not the brightest souls on this earth... OK? :silly:

FYI: To use this on your Tablet Z, you need the 2.5 BETA release, available on my downloads page!

See the BETA changelog header for the link to it!

After installing 2.5 Beta on my XTZ I see no evidence of this being a dual recovery - it just boots straight into CWM, no TWRP choice is given at any stage. How do I access TWRP?

TWRP is actually the main reason I flashed this because it's way better than CWM and hopefully later on there would be a separate installer for it, instead of dual one.

This may be a "newby" question, but what exactly would this be used for if installed on a locked bootloader? Like i read through and i saw that you can't use custom kernels/roms, so why would you need to reflash a stock kernel? Is the power to nandroid the only functionality?

You can select TWRP by pressing volume down, CWM by pressing volume up, as stated in the OP...

But I have to warn you, TWRP still needs to be fixed. It orientates the wrong way, the XTZ has its screen default in landscape and it was made for the default orientation of portrait.

I'll have that fixed sometime soon though. Loadsa stuff buzzin' on the XZ, so I haven't had the time to fix it yet.

There is no such thing as a "newbie question". Just take a look at my signature to see I'm not the only one who thinks that way

Custom ROM's can also be based on the STOCK ones created by Sony, with loads of customizations in them but specifically created to run on the STOCK Sony kernels.

Some app creators also do a flashable version of their app. Some people just don't like to use the play store for their testing versions.

The nandroid backups are very useful as a true full filesystem backup. The backup apps available on the play store do not always backup everything you have on your phone or tablet.

In general you can regard the recovery as a gateway to modding heaven. The question you have to ask yourself basically is "how much risk am I willing to take?" and the sky is the limit

Thanks for the reply. I don't boot into recovery using HW keys - its rather inconvenient. I use regular apps like QuickBoot, or Rom Toolbox, etc' which allow booting into it from the system - is there any way to set TWRP as a default recovery, so those apps would boot my XTZ into TWRP instead of CWM?

Can someone please confirm that twrp recovery supports exfat sdcard? The whole purpose of me installing recovery would be to nandroid backup to exfat formatted external sdcard.

Quoted from the OP:

Defaults:
The default on first boot with the boot-to-recovery flag set by any recovery is CWM.
You can however create a file called 'default' inside /storage/sdcard1/XZDualRecovery (if you have an external sdcard) or inside /cache/XZDualRecovery and simply put in 'twrp' (without quotes) to make it default to TWRP.
The button choice however takes precedence, so you can always overrule the default!

It should, as long as the kernel modules are installed and called texfat.ko and nls_utf8.ko they will be inserted in to the kernel by this recovery.

Installed and booted to CWM.

Tried to install a .zip that's in the root of the tablets memory, no option folder shows except from "clockwordmod/" and "0/" ?

Have a look inside 0/

What JB version ROM are you using?

Completely stock rooted. Looked inside 0/ and just has clockworkmod/ - inside that it runs and says no files found.

@[NUT] if I change the following:

Code:

  	#read default, for use with the boot flag file.
	if [ -e ${DRPATH}/default -a "`cat ${DRPATH}/default`" = "twrp" ]; then
		RECLOG="Booting TWRP by default..."
		RECOVERY="/sbin/recovery.twrp.cpio.lzma"
	else
		RECLOG="Booting CWM by default..."
		RECOVERY="/sbin/recovery.cwm.cpio.lzma"
	fi

to:

Code:

  	#read default, for use with the boot flag file.
	if [ -e ${DRPATH}/default -a "`cat ${DRPATH}/default`" = "cwm" ]; then
		RECLOG="Booting CWM by default..."
		RECOVERY="/sbin/recovery.cwm.cpio.lzma"
	else
		RECLOG="Booting CWM by default..."
		RECOVERY="/sbin/recovery.cwm.cpio.lzma"
	fi

and:

Code:

  	# Prepare CWM recovery
	if [ -f /system/bin/recovery.cwm.cpio.lzma -a "$KEYCHECK" = "UP" ]; then
		RECLOG="Booting CWM by keypress..."
		RECOVERY="/sbin/recovery.cwm.cpio.lzma"
	fi

	# Prepare TWRP recovery
	if [ -f /system/bin/recovery.twrp.cpio.lzma -a "$KEYCHECK" = "DOWN" ]; then
		RECLOG="Booting TWRP by keypress..."
		RECOVERY="/sbin/recovery.twrp.cpio.lzma"
	fi

to:

Code:

  	# Prepare CWM recovery
	if [ -f /system/bin/recovery.cwm.cpio.lzma -a "$KEYCHECK" = "UP" ]; then
		RECLOG="Booting CWM by keypress..."
		RECOVERY="/sbin/recovery.cwm.cpio.lzma"
	fi

	# Prepare TWRP recovery
	if [ -f /system/bin/recovery.cwm.cpio.lzma -a "$KEYCHECK" = "DOWN" ]; then
		RECLOG="Booting CWM by keypress..."
		RECOVERY="/sbin/recovery.cwm.cpio.lzma"
	fi

in dualrecovery.sh, will I then only have CWM which opens by both volume up and down? Or do I forget something?

Or maybe even better, can you tell me which changes are required in the normal CWM for locked bootloaders to run on the Tablet Z?

Maybe it's handier if we share some ideas over PM? I have some experience with recoveries; I've contributed to development of MIUI Recovery on the Meizu MX2: MIUI Recovery Mod by HR - Meizu Me

Hmm... what are you trying to do exactly?

To be honest, TWRP should be excellent for use on a tablet: touch interface :highfive:

If only I didn't run in to stuff every day that keep me from fixing TWRP

You (and anyone else for that matter) can PM me any time though, I really do not mind

That did not work. Created default file on external sd in the above location, put twrp in it, saved. Tried rebooting into recovery using 2 different apps - still goes to CWM

You can try to do the following command in a terminal app:

Code:

echo -n "twrp" > /storage/sdcard1/XZDualRecovery/default

I suspect your default file to contain a newline char and my checking of that file contents does not account for that...

With the above command it should correct that and work

I'm aware of android/Linux carriage return issues and newline char, and I made sure not to type anything after twrp, when I saved...I deleted the file i created manually and created another one, using command line above, but it made no difference. It still boots into CWM. I even tried reflashing 2.5BETA again, thinking something must have happened during the first time flash

Heh... ok, can you send me all the logs mentioned in the OP under 'error reporting'?

I'll need them to see what is going wrong then...

Really appreciate the personalized support and quick response times. I will do that tonight, but right now heading out to a couple of work meetings.

Take your time, I still need to fix TWRP before it will be of real use to you anyway

If only I had the cash to purchase a Tablet Z myself... That would make debugging so much easier...

Hi all,

Need help, I install the recovery, and the tablet automatically reboot to CWM, so I know the recovery installed correctly. But I can't access the recovery anymore after. I tried pressing the volume up button when the green LED is on no luck, tried pressing the volume up when pressing power button and holding both, not turning on, pressing the volume down when the green LED is on, no luck either, holding the volume down with power button will make the tablet go to safe mode. I tried flashing the reboot wrapper and boot using Goo and ROM manager to boot to recovery, no luck either. The only way I can get to recovery is to run the batch file again. Did I miss something?

Thanks in advance.
