Hi ranf,

I did based on your thread. Unsatisfied and still having issue with recovery.

Mainly is OTA update gone as I unlocked the bootloader in order to install recovery.

Although give up OTA, there was no permanent TWRP CWM Philz recoveries are able to install on SGP511.

What I did here is, I got temp TWRP given by your thread. Mean while, I installed pre rooted firmware by kulvertti.

Was the recovery, root, firmware are hook up each other?

Please kindly share If you got any idea about recovery which able to install on latest firmware with lock bootloader.

Anyway really appreciate for your info.
[Xperia Z2 Tablet General] nickbaker66:
Here you go mate click on the mega link and go to the recovery folder I used one of those IMG files and got 3.0.0 TWRP working https://mega.nz/#F!6RgEQJDK!xsZfjKz0xmViD_x2AFKrrQ
[Xperia Z2 Tablet General] Tunwin27:
Problem mate. I reckon to use flishfy to install image file after downloaded. Pop up error shows I could not install img as I don't have recovery partition. I can flash zip files.

Please help to advise.
[Xperia Z2 Tablet General] nickbaker66:
Hi mate I tried the same way and never got to work how I done it was make sure you've got android tools on your PC pen a command prompt window as admin then using make sure adb.exe is running then turn off tablet peer up volume button then plug in the USB connected to your PC blue led will come on confirming your in fastboot mode then type the following in the cmd window

fastboot flash recovery pathTo/recovery.img

(Path to is the location of where the recovery.img is stored)

Hope that helps
[Xperia Z2 Tablet General] Tunwin27:
I do have all tools. Flashtool/Sdk/adb/Prf and so on.

I've done that on latest official firmware with unlock bootloader. It's not work.

Anyway I will give a try your way again.

Just to verify. Now I was on pre rooted firmware. 23.5.A.1.291 6.0.1 with unlock bootloader.

Hope twrp will work with current my condition.

Mate thanks a lot.
[Xperia Z2 Tablet General] nickbaker66:
It should work mate after I flashed the recovery and rebooted when the pink light appears keep hitting the volume up button and you should just go straight into recovery
[Xperia Z2 Tablet General] saf4xdadev:
If you read and follow op and links then you see no need to unlock the bootloader, not to mention this isn't even the correct place to be discussing methods involving such. Kulvertti and others have posted many times over the correct way to use the prerooted firmware......starting with rolling back to rootable firmware and so on.......
[Xperia Z2 Tablet General] Tunwin27:
Good day Mate, it's worked.

I think my mistake on quick boot app as I thought by pressing recovery button it will send to me to recovery mode automatically.

Same thing on Pc, it wasn't on command fastboot reboot, adb reboot recovery.

Actually, it's need to play volume up and down buttons while device on green led to get recovery mode.

Sorry to bother all.

Thanks for the time and support.
[Xperia Z2 Tablet General] nickbaker66:
Glad it worked for you mate

Is there a mirror for that flashable bootloop fix? The links seems to be down and I need the fix.

Thx in advance,

[MENTION=5032335]kulvertti[/MENTION]: Thank you very much for the reupload and your constant support in this thread!!! :good:

/E: Just a quick update: I updated my SGP512 from "23.5.A.0.570" to "23.5.A.1.291" from the #1 post. At first sight everything was fine, the device booted and so on. But as I watched a video from a certain app the device just rebooted everytime I started a video. The solution was to flash the "bootloop fix" from the #1 post. Maybe this helps someone in the future with the same issue.
[Xperia Z2 Tablet General] SANGER_A2:
Does anyone else have issues with the dual part of the dual recovery? My rom is working OK with root and twrp, but I can't get into philz/cmw by tapping vol up (I have installed the bootloop fix BTW). I tried flashing the latest xzdual recovery from twrp and it a bootlooped and I had to redo the whole thing from ftf. When I installed ndrutils from the market (neither it nor supersu were installed by the flashable zip) it didn't detect the prop file and told me it was about to perform a factory reset when I tapped the reboot to primary recovery button!
[Xperia Z2 Tablet General] kulvertti:
That's because Dualrecovery isn't compatible with this firmware version anymore. Neither NDRUtils. So only custom recovery installed is TWRP.
[Xperia Z2 Tablet General] SANGER_A2:
LOL. That explains it. Thanks. I wish NUT had mentioned that on the dual recovery download page.

It's annoying though as the backup of my old rooted stock system was with Philz and if I want to go back I'll have to ftf an old rom, root it and then flash my previous installation backup. So far this seems to work well.
[Xperia Z2 Tablet General] kulvertti:
OP updated. No new firmware anymore but TWRP is now 3.1.1.0 and SuperSU 2.79 stable.
[Xperia Z2 Tablet General] SANGER_A2:
In the end I flashed back to rooted stock android 5 again. This is the second time I've tried android 6 and gone back to 5! Youtube didn't work well, even after I removed the system app and addons and reinstalled from the market. Also, I had major delays with connecting to Wifi after sleep and the battery life was worse. My android 6 and 7 on my Sony X Compact work great. It's a shame Sony just haven't tried very hard with the software updates for this device. :(
[Xperia Z2 Tablet General] sofir786:
I've honestly had no issues at all on latest rooted firmware, battery is good, no wifi issues at all on my WiFi only device.
[Xperia Z2 Tablet General] stroemungsgleichrichtrr:
I flashed newest ROM from op, but somehow, I do not have root. Titanium Backup said no root found, so I tried to install SuperSU from PlayStore which says "root undetected". Any ideas how to fix this? Thanks in advance!
[Xperia Z2 Tablet General] kulvertti:
You could try to flash working SuperSu zip file from Chainfire via TWRP. Link below is latest test build.

http://download.chainfire.eu/1114/SuperSU/SR1-SuperSU-v2.82-SR1-20170608224931.zip

If not succeed I need more info like how are you rooted before trying this rom, do you dirty flash or clean flash, what rom you came from etc.
[Xperia Z2 Tablet General] stroemungsgleichrichtrr:
Thanks for your help, kulvertti, works fine with SuperSU zip.
[Xperia Z2 Tablet General] kulvertti:
Just to notify if someone intrested. I post flashable Android O system emojis here:

[Xperia Z2 Tablet General] kulvertti:
Sorry, can't find it at the moment atleast. However there are several other rooting methods which are working just fine and without installing any malware. One even in this device general forum. Good luck.
[Xperia Z2 Tablet General] Bastlwastl2010:
On my wifes sgp511 is the last cyanogenmod 12.1 with TWRP 2.8.7.0 installed (no dualrecovery)

I ask bevore i flashed, because on sony devices i have always trouble....

it is save to flash this rom with the the TWRP 2.8.7.0 on the device clean erverything and voiala...its done

or is there any trap on this way?
[Xperia Z2 Tablet General] kulvertti:
There shouldn't be any problem if you wipe system, data and both caches. If problem occurs flash Sony stock fota partition with Flashtool. This should be quite safe process with backup but as usual you do it with your own risk.
[Xperia Z2 Tablet General] SANGER_A2:
Don't forget to relock the bootloader too or this stock ROM won't work! You will have had to unlock it to get CM on.
[Xperia Z2 Tablet General] Bastlwastl2010:
Thanks, i know there is a trap.....

So..first i restore my ta partition (i have a backup :D)

bootloader is locked

reboot into TWRP (hope it is not deleted after restore ta partition)

flash this rom

hope i have fun

Right?
[Xperia Z2 Tablet General] SANGER_A2:
I have unlocked mine, installed CM and then relocked it and gone back to this ROM in the past. Long time ago and I can't remember how I did it unfortunately! :) I know that you can unlock the bootloader using flashtool, so you can probably lock it again too! http://www.flashtool.net/index.php
[Xperia Z2 Tablet General] kulvertti:
Well, if you want to lock your bootloader make sure you are on stock kernel first and after that you can lock it, not before.

One reason why full wipes are necessary is that you don't end up with two TWRP installed. With this device TWRP could be installed in fota partiotion or in system partition (like this rom) and you likely have it now in fota partition.
[Xperia Z2 Tablet General] Bastlwastl2010:
Not necessary do lock the bootloader with this rom?
[Xperia Z2 Tablet General] kulvertti:
It's up to you as far as I can tell. I don't remember if I use this latest version with unlocked bootloader or some previous version but for me it worked just fine then (exept drm key dependent part).
[Xperia Z2 Tablet General] SANGER_A2:
I'm pretty sure when I switched back to this ROM it didn't work until I relocked the bootloader and Kulvertti was the one who helped me out with that! :) He's very kind with giving his time to help others. :good: The conversation may still be somewhere in this thread or another one, but I can't be bothered to search back for it.
[Xperia Z2 Tablet General] kulvertti:
Thank you for your kind words. I appreciate your feedback very much.

Which is the latest Firmware (Non rooted) for the SGP521 ?

I have 23.5.A.1.291, but I read somewhere there is a later one.

My battery is at the end - is there a tutorial how to change ?

iFixit has an exellent one but that is for the Z model, Not the Z2...

Best

Kami
[Xperia Z2 Tablet General] joeyishar:
These are really well built tablets. Nearing the point where they are a relic of a different time.

Look at a tutorial on replacing the screen and you should see the battery is really easy to get out in the process. The process of removing the screen and replacing the battery follows the same process of opening the tablet as replacing the screen.

Options for actual replacement batteries are sparse. I think buying from Amazon is safest (because of their return policy), but Im not sure because the order is sold through a non Amazon retailer (Amazon should still have a strong return policy if it's defective)

There were a bunch of other options in Google shopping (although Amazon is least expensive)

Post if you have more questions
[Xperia Z2 Tablet General] cryss83:
Hello guys,

sorry to open this post again, but i really need your help....instead of flashing the boot.img from the z2 tablet, i used the boot.img from the phone...so i wanted to ask if there is any way how i can revert this (before you ask: no backup of my old boot.img)..is there any way how you can extract from the image above a boot.img or something like that? all help is appreciated!!! Thank you!

Fastboot is still working

FlashMode is working as well
[Xperia Z2 Tablet General] kulvertti:
If you allready have your tablet firmware .ftf -file just flash fotakernel.sin with flashtool.

Also you can extract boot.img file from .ftf file if you want. First you need your tablet .ftf file. Then extract that with 7-zip and find fotakernel.sin -file. Open fotakernel.sin -file with Flashtool Tools -menu Sin Editor and click Extract Data. Then just rename fotakernel.elf -file to boot.img. Done.
[Xperia Z2 Tablet General] cryss83:
Thank you very much.

And how to proceed from there if i want a custom rom?

I have already unlocked the bootloader, but as others i can't use twrp since i can't get into that (no led flashing at the start - which was the reason why i wanted to flash a different boot.img)

Is there a way to write a custom rom via fastboot?

Sorry for those possibly stupid question... I've always wrote via twrp on other devices...

And if that was possible i would really prefer that.

[Xperia Z2 Tablet General] kiffschwein:
thx dude!

i got a problem now, maybe someone could help me please!?

as it says: "pre-rooted", but i got no root access :(!

i already tried to install/flash supersu over recovery, but no luck. the installer installs, and where it says something about ramdisk, the installer aborts.
[Xperia Z2 Tablet General] kulvertti:
Do you have root access before flashing this rom? If you have, this should flash SuperSu with rest of the rom.
[Xperia Z2 Tablet General] kiffschwein:
no! ofw and locked bootloader till 2 weeks ago!!!
[Xperia Z2 Tablet General] kulvertti:
You need to be rooted but you can flash this with locked bootloader.
[Xperia Z2 Tablet General] kiffschwein:
the tablet was ofw and locked before i got it - like 2 weeks ago! now i unlocked the bootloader and flashed this pre-rooted fw... so, bootloader status=unlocked!

after that, i tried flashing supersu.zip over recovery, but no root... no root before flashing supersu, and also not after!
[Xperia Z2 Tablet General] tanis73:
Is the link work for a SPG512?
[Xperia Z2 Tablet General] kulvertti:
Yes, you can use it with SGP512.
[Xperia Z2 Tablet General] tanis73:
Well.... Rom installed correctly and worked fine. Just one thing I didn't understood was why my tablet was partially rooted (recovery available but rooted applications blocked) so I tried to flash Supersu v2.82.zip under twrp, this failed r/w was denied, I also tried with TabZ2-lockeddualrecovery2.8.26-RELEASE.combined.zip from Nut and I lost my recovery....:rolleyes:

I'm thinking about a locked boot.img, Am I right? If I did something wrong, any advices are welcome and looking for a unlocked boot.img working for my sgp512 windy :rolleyes:
[Xperia Z2 Tablet General] kulvertti:
You don't need to have unlocked bootloader for this to work. Nut's dual recovery however is incompatible with this.
[Xperia Z2 Tablet General] tanis73:
Good to know.... :/

If I flash the boot.img included in your rom, it will be ok? This is the only way I found to flash and access to the recovery on my tablet

Also, what was the problem about this partially rooted condition? :confused:
[Xperia Z2 Tablet General] kulvertti:
I don't think it's going to work by just flashing that boot.img.

Information you gave to me its hard to know what went wrong. Maybe it is Sony ric thing or tools you're using or something else. In op there is info how to do it.

[MENTION=5032335]kulvertti[/MENTION] Hi, I bricked my tablet and now all I have is fastboot mode. I am unsure of how to use the Androxyde flashtool and the files you have provided. Would you be kind enough to do a step by step? Thank you so much for your help :)

I'm currently running Ressurection Remix Oreo 8.1 rom, and i want to flash this since i have some trouble with battery drain. Should i be able to just flash this zip through my twrp recovery, or do i need to do something extra? I unlocked my device and flashed the RR rom directly from official KitKat

EDIT: Okay i think i was too impatient. Went into TWRP and flashed this zip, and my device boots up with the sony logo, then android text, and then the blue waves is shown and seems to be looping forever. I get no purple led at the sony logo so i cannot access my recovery it seems. Tried to boot into fastboot and flashed twrp_3.2.1-cw.img which succeeds, but i still do not get any purple led so i still cannot access it.
[Xperia Z2 Tablet General] kulvertti:
Sorry to hear that. I think that problem is that you ended to device with two TWRP installed which are not compatible with each other.
[Xperia Z2 Tablet General] Da9L:
Not sure what caused it. I flashed the boot.img from the Ressurection Remix rom and then the twrp (3.2.1) i used there. Now I'm at least able to access recovery again and flash roms, but not sure how to get this one to work. So for this to work i should use a specific TWRP version or?
[Xperia Z2 Tablet General] kulvertti:
It happened because your previous TWRP is installed in different place in your device than TWRP used in this rom. By flashing this rom you don´t remove earlier TWRP from your device but have two TWRP. So if you want to flash this rom you need to remove your earlier TWRP first.
[Xperia Z2 Tablet General] Da9L:
Is there any guide somewhere on how to do that?
[Xperia Z2 Tablet General] redlabour:
Any 5.1.1 Update?
[Xperia Z2 Tablet General] kulvertti:
There will be when Sony release one for our device.
[Xperia Z2 Tablet General] myeepad:
Thank you, Kulvertti, we have faith on you, so pre-rooted please...:p
[Xperia Z2 Tablet General] rockknee:
My point is now that I have twrp on fota partition will the sony stock stuff interfere the flashing process?
[Xperia Z2 Tablet General] kulvertti:
It shouldn't. By clean install I mean wiping system, data and both caches. How ever if problems occur you can always flash Sony stock fota partition via Flashtool excluding everything else.
[Xperia Z2 Tablet General] rockknee:
Okay, I'll give it a try and see what happens. Flashtool is always good to have as plan B :D
[Xperia Z2 Tablet General] kulvertti:

And are there any differences in battery life or in fluidity?

I have an odd issue. After flashing the 23.4 version, I got a notification that said something like "No data service available" after the first boot.

I could swipe the notification away and it didn't return, but now I have a permanent notification on the top left that says "No service", but it's only showing on the lock screen. If I swipe the notification bar down, the notification disappears. It's also not visible when the tablet is unlocked.

Looks like some kind of reference to a missing 3G connection, but my tablet is the SGP511 wifi only model.
