Hi, just received a 4.1 SGP312 today, rooted with DooMLoRD_Easy-Rooting-Toolkit then updated too 4.2 via OTA after moving supersu to /system --> root is still there.
Now i would like to install a custom recovery and after reading all the treads concerning recovery i'm lost : is there any recovery woking atm for a 4.2 rom on locked bootloader for a SGP312 ?

Maybe someone will correct me on this, but I thought recovery required a non-stock kernel, and insralling a non-stock kernel requires the boot loader to be unlocked. So, you can't have recovery on a locked bootloader with stock ROM.

Nope, if you want a custom recovery you'll need to unlock your bootloader. In case you wan't to keep your DRM keys nad relock bootloader afterwards, backup you TA partition, unlock your boot loader, flash 4.2.2 kernel with custom recovery ('https://mega.co.nz/#!vV8QHKaI!Zpxtii1zictYur7sVOVRVVk0lR8tdIDOSmaDQkL8QDk'), flash root from recovery and finally reflash your TA partition which also relocks your bootloader.
Hey guys,
I was wondering if it's all possible to flash CWM or TWRP on the TF201 with a locked bootloader. My tablet has been fully rooted but the bootloader is locked (bootloader is Jelly Bean version, bootloader unlock tool is ICS only). I was wondering if there's any way to backup stock recovery and flash TWRP/CWM on the device even though the bootloader's locked.
Cheers,

Hi!
Somebody in a different forum suggested that it might be possible to root the latest firmware (23.0.1.A.0.167) by downgrading the kernel (http://forum.xda-developers.com/showpost.php?p=56590546&postcount=1224).
Can anybody confirm this method to work?
I purchased my Z2 tablet yesterday and was foolish enough to believe that I can upgrade to the latest firmware and still root my device (with a locked bootloader).
Greetings

It doesn't work. You end up to bootloop. However you can flash prerooted firmware in custom recovery and have fully rooted device.

In order to do so I have to unlock my bootloader and with that I'm going to lose my drm keys, right?

No. If you easy root and install the dual recovery beforehand you flash from that.
But easy root doesn't seem to work with the latest firmware, they closed the vulnerability that easy root is using

Easy Root Tool works just fine with .314 firmware. So if you are now on latest .167 firmware, downgrade to .314, root it, install custom recovery and flash prerooted flashable.zip in custom recovery. Done.

Ah, I didn't know it's possible to downgrade the firmware
So I need the firmware flash tool and a ftf file of the 167 firmware, right?
And it can be done without root and a locked bootloader?
Sorry for all the newbie questions, I'm coming from HTC devices and it's a little different there

You need:
- latest Flashtool with drivers installed correctly for your device
- some working custom recovery
- Easy root tool
- ftf file you need is 314 firmware of you device where you have to downgrade to easily root it
- prerooted zip file included you device 167 firmware, SuperSu install files and latest dualrecovery install files.
You don´t need unlocked bootloader for this. Point of downgrading is to achieve root easily that you can have root with 167 firmware? Or do you mean that can you achieve root on 314 firmware without having it before? If so, yes you can with Easy root tool.

thanks for your efforts!
in the meantime I managed to downgrade the firmware to 314, successfully root and backup TA
I installed superSU from the play store and it is telling me that I need to update the binaries and I can choose between "normal" (which doesn't work) or through "twrp/cwm"
I didn't install any custom recovery yet, so I'm not sure how to move on from now
should I install dual recovery (from here: http://forum.xda-developers.com/showthread.php?t=2785598), after flash the latest supersu from recovery and finally flash prerooted zip file?
do I need custom recovery to flash the prerooted 167 firmware?
or should I just run the OTA to get 167 firmware (will the device still be rooted after the update)?
please advice

Good to here you achievment. If you can´t update SuperSu binaries by "normal" way easiest might be to flash SuperSu latest update from custom recovery. I recommend dual recovery from your link and when installed use TWRP.
So install dualrecovery, flash latest SuperSu and then prerooted zip. If you end up without write permissions to system here might be solution for that.

i went through philztouch dual recovery. but it doesnt work after repeated attempts. so i want to know if there is any way to install cwm or twrp on locked bootloader.

Hi guys,
After seeing so many issues with unlocking bootloader, I decided to root on a locked bootloader. However, is it possible to install zips on a locked bootloader? Eg. V4A?
We have a working recovery for locked bootloader (see [NUT]'s dual recovery in the cross device development section). So yes it is.

I think I have that installed alr. So I can just flash a zip from the recovery? Can I flash custom roms, and is xposed for locked bootloader working?

Yes you can just flash from recovery.
You can only flash SONY STOCK custom ROM's.
Xposed works fine for me on my locked bootloader.
