[Xperia Z2 Tablet Original Android Development] Gnopps:
I wrote Sony to ask about warranty when unlocking the bootloader, as hardware failures ought to be covered still. This is the (somewhat ambiguous) reply I got:

Gnopps:

I recently purchased your tablet Z2 with the extended 3 year warranty. Would you please let me know how unlocking the bootloader (http://unlockbootloader.sonymobile.com/) to enable for example rooting (gaining full access to the device software) the tablet will affect the warranty in terms of _hardware_ failures? My understanding is that hardware failures of a rooted unit will still be covered by the warranty, software failures will not be covered. Is this correct?​

Sony:

We thank you for your feedback, and hereby we can confirm that we have been doing research on your behalf that indeed you do it, but then we cannot guarantee you if the support will support this case if something will happen in the future. If it needs service the chances the the settings will be default again.

Should you have further questions, please contact our customer service.

At the same time we wish you a nice day further.​
[Xperia Z2 Tablet Original Android Development] SANGER_A2:
Wow! Did Sony write that using Google Translate or something!?! How completely unclear.
[Xperia Z2 Tablet Original Android Development] bacon612:
Can we get some specifics on what sorts of things wont work after you loose drm keys? I just picked up this tablet today and want to root and install cwm. Its been years since ive had an android without root.
[Xperia Z2 Tablet Original Android Development] SANGER_A2:
If we install this recovery and then upgraded to a newer stock rom would we lose root and recovery?​
[Xperia Z2 Tablet Original Android Development] istrait:
I would like to know the same thing. What is broken when you do this?
[Xperia Z2 Tablet Original Android Development] hasenbein1966:
X-Reality (superfluous anyway) and Sony DRM keys. Services like Kindle or Google Books/Movies etc. work normally on my unlocked and rooted device. If you don't want to buy movies or music or such stuff from Sony (why should one want to when there are other and better services?), then just go ahead and unlock if warranty is not an issue for you.
[Xperia Z2 Tablet Original Android Development] Ricky D:
Updating over the air and through Sony Update Service is also broken when you unlock the bootloader.

This is the major difference not to my liking.

I will not unlock my bootloader until there is looking like a good base devs supporting the device. I don't fancy being left in the lurch on an old FW with no where to go.

Hi [MENTION=2784807]DooMLoRD[/MENTION] quick one, i see the download for LTE now, but title still says wifi only, but it will work with working LTE connection right?

Lost Wifi after unlock and CWM flash

Hello,

I just unlocked my device SGP521 (LTE) and installed CWM (thx Doomlord!), everything went quite smoothly, but after reboot, the wifi was lost and can't be re-activated.

Any idea how to reinstall original bootloader to check if unlocking or cwm bootloader is causing this issue?
[Xperia Z2 Tablet Original Android Development] pmartin:
Hello!

The cwm at the post #24 works fine!

my wifi works!

The LTE function not tested no LTE availiable at my area!

regards

peter
[Xperia Z2 Tablet Original Android Development] RicoVDO:
Thx Peter, I solved the issue by reflashing .69 FTF release back, then reinstalling CWM.
[Xperia Z2 Tablet Original Android Development] stephenyu:
cannot power on

After I install Kernel rom. The device cannot power on.
[Xperia Z2 Tablet Original Android Development] hasenbein1966:
Most probably a noobish question, but:

When I (having an unlocked and rooted SGP511 with FW .36) would flash an FTF of the upcoming .69 update, then CWM recovery as well as root would be gone, right?

Is there any way to update the firmware while retaining recovery & root? Or is it only possible after Doomlord has released a new version of this kernel for the .69 FW?
[Xperia Z2 Tablet Original Android Development] UserX10:
Checked it with this FW .69 and the modified Kernel from DooMLoRD for the .55 Kernel. Worked like a charm...
[Xperia Z2 Tablet Original Android Development] hasenbein1966:
Er... thanks, but what exactly did you check?

Did you have a device with. 55 FW already rooted and then upgraded to. 69 retaining root?

Or did you have an unrooted device with locked bootloader which you first upgraded to. 69, and then you did the unlock & root thingy?
[Xperia Z2 Tablet Original Android Development] UserX10:
Both versions work with unlocked bootloader:

Flash complete .69 FW and root -> worked

Upgrade from .55 to .69 excluding kernel (because it is the same) -> CWM is still availalbe -> worked
[Xperia Z2 Tablet Original Android Development] hasenbein1966:
Very good! So I just have to wait for the update :)
[Xperia Z2 Tablet Original Android Development] Stirius:
So still no flash without unlocking bootloader?? :( Im waiting for it...

[Xperia Z2 Tablet Original Android Development] hasenbein1966:
I have same tablet model, same firmware, also unlocked and rooted - no problems whatsoever.

Must be another problem which is unrelated to unlock/root...
[Xperia Z2 Tablet Original Android Development] asjstian:
might be so. but forgot to mention that i have also done a factory reset, but did not help. for now i have turned off sync, but would really like to get this fixed
[Xperia Z2 Tablet Original Android Development] stephenyu:
My firmware is 69. I cannot find 55 firmware
[Xperia Z2 Tablet Original Android Development] asjstian:
Update. Seems stable now, done a complete restore, and wipe dalvik /cache.. Suspecting app Causing problem. Installed kitkat SD card fix from app store, and now it seems that this was causing my problems, been running without now and everything is stable.

Can be concidence, if anybody has an opinion please share :D
[Xperia Z2 Tablet Original Android Development] hasenbein1966:
Hello Doomlord,

for the SGP511 now the new firmware 17.1.A.402 is rolling out! Some German users already have it, PC Companion shows it for me, too!

Now, the kernel of the .36 firmware is

while the kernel of the .402 firmware, according to a screenshot a user posted at the "android-hilfe" forum, is

So my question:

Are the kernels equal/similar enough so that I can flash the update without losing CWM or root? (SuperSu on "survival mode")
[Xperia Z2 Tablet Original Android Development] hasenbein1966:
Tested it :silly:

Doomlord's kernel is NOT compatible with the .402 firmware :(

Uploading .402 FTF for SGP511 now so that a new Doomlord kernel can be made...
[Xperia Z2 Tablet Original Android Development] DooMLoRD:
just upload the kernel.sin for each device (SGP51x & SGP5x1)
[Xperia Z2 Tablet Original Android Development] nos1609:
hope it would help you:good:
[Xperia Z2 Tablet Original Android Development] dav010:
Hi all,

I've an SGP511 (17.1.A.2.36 firmware) and successifully rooted last week with DoomLord kernel.

Now I'd like really to update to .402 firmware to verify mostly touchscreen fix but I know I can't do it "normally".

I tryed to re-lock my tablet with FlashTool, but although it say everythig was ok at the reboot the unlok is still there.

Any change to update to .402?

Just flash any FTF...
[Xperia Z2 Tablet Original Android Development] asjstian:
Any hope of seeing magnificent doomlords kernel supporting. 402 firmware soon?

Really wold like to see touchscreen issues dissappear, but not on behalf of my root access ;)

Most important: a big, very big thank you to doomlord, for all you great contribution to everything! Most appreciated by us noobs :)
[Xperia Z2 Tablet Original Android Development] hasenbein1966:
Since on the Z2 phone there is already support for .402 and the kernel.sin is available, there definitely is hope for support coming soon.

But since Doomlord does these things for free in his spare time, pushing him with requests is not nice.
[Xperia Z2 Tablet Original Android Development] pmeinert:
You can still be rooted on 402, which I am, but require a bit more work.

1. Download super user and place the zip on your device

2. If you use xposed, then change update style to manually by zip and take note where it is saved.

3. Use Flash tool in flashmode to get 402 flashed, remember to uncheck wipe of data, if you want to keep your stuff.

4. Start in fastboot mode and flash the old kernel with recovery from this thread

5. Boot into recovery and flash super user and xposed zip

6. Go Back into fashtool and flashmode. Flash 402 again, but uncheck all wipes and ignore everything but kernel

Viola. 402 and rooted. But no recovery unless you temporary switch kernel as above.
[Xperia Z2 Tablet Original Android Development] DooMLoRD:
I already have kernel.sin files for these devices... Please wait will try and get test versions ready in a day or so...
[Xperia Z2 Tablet Original Android Development] Stirius:
DooMLoRD and do you think that there will be version in the near future where we will not loose our warranty because of bootloader? Or is it what you are up to right now? I don't understand much these things. BIOS in "pc world" and other definitions are fine but definitions in mobiles are foggy for me :).
[Xperia Z2 Tablet Original Android Development] DooMLoRD:
Well that will depend on how easy it is to find a working exploit...

So far we are not getting any useful exploits...
[Xperia Z2 Tablet Original Android Development] Stirius:
Ok, we will see then, thanks. The fact is that I hate locked SD card, adds everywhere, apps I cannot install etc. But unfortunately all these things are not worth of my 3 years warranty :(
[Xperia Z2 Tablet Original Android Development] DooMLoRD:
BLIND TEST KERNELS WITH RECOVERY!

Maybe a noob question, but Should i be on the .402 first?
[Xperia Z2 Tablet Original Android Development] ViP®:
it works, thanks :good:
[Xperia Z2 Tablet Original Android Development] asjstian:
So you had .402 before flashing this kernel right?...
[Xperia Z2 Tablet Original Android Development] lizardking75:
I had .402 before flashing, on Wifi only version works perfectly, thank you :)
[Xperia Z2 Tablet Original Android Development] DooMLoRD:
thanks!

can someone confirm that it works for the WIFI Only variant too?
[Xperia Z2 Tablet Original Android Development] hasenbein1966:
Yes, works perfectly on SGP511! Thank you very much!
[Xperia Z2 Tablet Original Android Development] asjstian:
will not boot on my SGP511 wifi only. just used falshtool to update to .402. and, fastboot to install latest kernel.

Boots, and see sony logo, then nothing happens. can still boot to CWM recovery

---------- Post added at 09:51 PM ---------- Previous post was at 09:37 PM ----------

Done all the above all over again, and full wipe. Boots, see sony logo and hear boot sound, but no picture. Screen stays bright but blanc.:eek:
[Xperia Z2 Tablet Original Android Development] hasenbein1966:
You most probably used the wrong version... Must be the 2nd one of the two kernels in the above post...
[Xperia Z2 Tablet Original Android Development] asjstian:
have downloaded the 2nd one 2 times now :silly:
[Xperia Z2 Tablet Original Android Development] pmeinert:
I just did it without problem on my sgp511. The file you download should be boot-0.402-sgp51x_WIFI.img and flash it with fastboot flash boot.
[Xperia Z2 Tablet Original Android Development] pmartin:
Hey guys!

Hello!

What do you mean? I have flashed only the img from here!

The Update via PCCompanion does not work, because it ends with the message: There ist wrong software installed!

---------- Post added at 02:04 PM ---------- Previous post was at 01:51 PM ----------

Hello DooMLoRD,

flashing works, rebooting too!

I see the "sony" sign and hear the booting sound!

But thats it! I see the device at the explorer on my computer, thats all!

Nothing else going on!

Do you have an idea?

regards

peter
[Xperia Z2 Tablet Original Android Development] hasenbein1966:
*rolling eyes* OK, then you obviously don't have the .402 update yet, and then of course the new Doomlord kernel version is wrong!

You need the one for .36 firmware!

If you don't know about firmware versions and how to find out which one your tablet has, then probably this whole flashing thing is not (yet) for you... It's only for more experienced users.
[Xperia Z2 Tablet Original Android Development] pmartin:
Hey hey!

Come on! My actual version of the software is: 17.1.A.2.55

So the next is .402 or not! The tablet is rootet!

So i don´t know whats wrong?

regards

Peter
[Xperia Z2 Tablet Original Android Development] hasenbein1966:
OK, once

more

:

If you could read properly, you would know that for the .55 firmware on the LTE model you need the kernel suited for .55 and not the one for .402 which you tried.

Is all in the 1st post of this thread!
[Xperia Z2 Tablet Original Android Development] pmeinert:
What is wrong is that you need to match the kernel with the right rom.

This thread is only the kernel, which has been modified with recovery, to help rooting etc.

Since you have unlocked your bootloader, updating the rom in traditional way is broken (I guess, because it normally is, but I am not that experienced with sony's devices), therefor you need to update the rom with flashtool (get it from flashtool.net). For the very same reason the general forum is floating with ftf-files of roms for the different variants. So find the one which matches your device and flash it with flashtool. First after that you go back here and flash this modded kernel. Remember NOT to wipe data during the process, if you want to keep you stuff on the device.
[Xperia Z2 Tablet Original Android Development] asjstian:
DoomLord; can you tell if you have written any support for this: http://www.devasque.com/foldermount/kk-support.html in this kernel..?

Having some trouble mounting the obb folders (cant mount).

Best regards
[Xperia Z2 Tablet Original Android Development] hasenbein1966:
Doomlord's kernel has no special features except being insecure and having CWM. It's just for being able to have root and having a custom recovery.
[Xperia Z2 Tablet Original Android Development] DooMLoRD:
THIS particular is using pure stock core kernel... so what features u see on stock sony kernel will be here...

on top of that it has CWM inbuilt, debugging enabled, some hacks to make root "stick" (no reboot on system remount issue)..
[Xperia Z2 Tablet Original Android Development] jlariviere:
I followed the directions for unlocking the bootloader on my z2, and now it will not boot, will not turn on, no lights light up, will not enter into flashboot mode, nothing.

[Xperia Z2 Tablet Original Android Development] pmeinert:
Try holding power+volume up for a few seconds till you fell the vibrator. Then it is powered off and you can try to turn it on again.
[Xperia Z2 Tablet Original Android Development] jlariviere:
Tried that, didn't work. No vibrate. :(

Thanks for the suggestion, though...
[Xperia Z2 Tablet Original Android Development] hasenbein1966:
Press Volume Up first, then add Power. Then really hold them together for some time, don't release too soon.

If that really doesn't work, your device is hard-bricked and you have to send it to the service.

Hello everyone I wanted to ask if you can have DooMLoRD the TWRP recovery I am very well.

I tried to install the Z2-lockeddualrecovery2.7.124 okay but you can not see everything in half.

The cwm works well great job.

I apologize for my inclese
[Xperia Z2 Tablet Original Android Development] hasenbein1966:
Er... this is the forum for Z2 Tablet, not Z2 phone, not Tablet Z. (Just sayin'...)

For Z2 Tablet, as you should have seen, ATM there is only this CWM recovery available. No cross-device install possible.
[Xperia Z2 Tablet Original Android Development] alfa_156:
Thank you very much for your reply.

I expressed myself badly, so I have xperia z2 tablet sgp511 just wanted to know if it was possible.

I unlocked the BL with the cwm recovery and it all works.

I also xperia z1 c6903 as a shelter I have TWRP I feel good.

All of them .....

hey guys I have updated my Xperia SDCARD Mounter app to support this phone!

what does the app do?

It will allow you to connect the external SDCARD as a USB Mass Storage device....

so basically the sdcard will act as a USB stick/pen drive...

you can use the classic/advanced copy manager (TotalCopy, etc) which gives u greater level of control and possibly better copy speeds (though this is debatable)...

also the internal sdcard will be now be easily mounted on linux devices which have issues recognizing MTP connection...

hope you like it!

regards,

DooMLoRD
[Xperia Z2 Tablet Original Android Development] SANGER_A2:
You should start a separate thread for this as well to let more people know and get more money for yourself too!

Don't forget to emphasise again that it needs root! There are always some idiots that buy apps without reading all the description and then leave bad feedback when it doesn't work.
[Xperia Z2 Tablet Original Android Development] DooMLoRD:
Ya there is already a thread for that :)

Anyways please do keep reporting if you run into any issues with this kernel!

Hi, i want to root mi z2, but as i understand, i should make a TA backup before unlocking the bootloader, BUT to make that backup i need to root the tablet and for rooting the tablet the bootloader must be unlocked.

I'm a bit lost, what should I do?

Thanks.
[Xperia Z2 Tablet Original Android Development] pmeinert:
You can't root without unlock, so currently backing up ta is not possible and you have to skip that step and accept, that reverting 100% back to original will not be possible.
[Xperia Z2 Tablet Original Android Development] troon95:
Thanks, then i will wait for a method to root the tablet without unlocking the bootloader, i principally wanted it to install adaway, but i guess i can wait.
