Z2 Tablet self reboots after boot

so wipe everything and made a factory reset, then flashed the zip, after the reboot the nfc software update dialog appeared and after that it rebooted, now is on a bootloop. I dont know why, never happened this before :(. I cant find another zip with this update, if anyone knows how to fix this iI'd be really grateful.
[Xperia Z2 Tablet General] kulvertti:
At the moment you have atleast two choices. See post #256 how to fix your problem.
[Xperia Z2 Tablet General] redlabour:
Any update to 23.5.A.1.238?
[Xperia Z2 Tablet General] kulvertti:
Not yet.
[Xperia Z2 Tablet General] BLiapis:
Hi, i installed the prerootef 6.0.1 file, but whenever i plug it on the charger, it reboots. Tried to clean delvik cache and normal cache, but to no avail. I also have the exposed framework installed, which seems to be working.
[Xperia Z2 Tablet General] kulvertti:
Never heard this before. You may try if instructions in post #256 can help you too. Maybe also try to start your device to safe mode and see if it reboot also there. If either works getting log when reboot happen might be good idea. Good luck.
[Xperia Z2 Tablet General] BLiapis:
My device can boot. But as soon as i plug charger, it will reboot into a bootloop.

Truth be told, i didnt prepare the tablet for the upgrade (by cleaning caches). I just installed the package.

It worked. Kinda.

---------- Post added at 10:18 AM ---------- Previous post was at 09:22 AM ----------

The bootloop fix file worked. I do plug in my charger and no boot/bootloop happens.

Thanx Kul for your contribution all this years, stay true!

#noob here. I can't find a good explanation un how to flash this zip. My sgp512 has an unlocked bootloader, but I can't find a way to install a working recovery. What recovery are you using to flash this ?

thx
[Xperia Z2 Tablet General] kulvertti:
This zip file need to be flashed with custom recovery (TWRP recommend). How to install TWRP to your device depends which ROM and version you have now installed?
[Xperia Z2 Tablet General] enorrmann:
Im running this rom from xperifirm

I can't find this device on TWRP's page
[Xperia Z2 Tablet General] kulvertti:
As your bootloader is unlocked you have several choises how to install working recovery. Before trying anything make a backup and make sure you have knowledge how to recover if something go wrong.

Go here http://xdaforums.com/z3/general/wip-sony-android-6-0-mm-t3337357 and install RecRoot for locked/unlocked bootloader via pc. Notice that you need rooted device to install this. However this option working flawlesly. I recommend this option.

Second choise is in same place to install custom stock kernel with recovery included via fastboot mode. I haven´t try this and it may not work at all because it´s different device kernel.

Third option is find other stock kernel for your device with recovery included maybe from android development or original android development section of Z2 Tablet XDA -forums.

[Xperia Z2 Tablet General] kulvertti:
Sorry for the late answer. It's beeing holiday season so... Maybe trying several times help or asking that tool thread how to fix your problem. Also you can always downgrade to .314 firmware and use another tool. And last there are interesting threads in Z3 Compact forum how to root properly latest firmwares.
[Xperia Z2 Tablet General] kulvertti:
I could upload flashable .zip -file or recovery.twrp.cpio.lzma - file but don't have .img file sorry.
[Xperia Z2 Tablet General] kulvertti:
I'v been waiting update for several days now but seems that this device isn't first in the line. I will update soon as we have it.
[Xperia Z2 Tablet General] kulvertti:
Correct. Choose option for unrooted device from [NUT] installer and it root your device before it install Dualrecovery.
[Xperia Z2 Tablet General] hermovv:
Thanks for making this clear!
[Xperia Z2 Tablet General] joeyishar:
screwed

I figured out my issue. when i flashed boot.img, i didnt flash it as boot. I flashed it as the whole rom. now my tablet wont connect to my pc and cannot resotre because everything is gone. I tried to "Wipe data/factory reset", but I think that made it worse. please help, I cant figure out how to let ADB connect to my tablet. I just keep getting an error about device not found.
[Xperia Z2 Tablet General] kulvertti:
Sorry to hear. Try to install your firmware (ftf file) again with Flashtool in flashmode.
[Xperia Z2 Tablet General] joeyishar:
still having problems

Ok, I got it fixed (thanks btw). I now cannot figure out how to flash dualrecovery. the internet tells me that either there is an install.bat (there is not) or i can find the img in the tmp folder (also isnt). I went to a thread that had the extracted twrp, and also found that I need to flash recovery not boot. I did this, but no I cant reboot to recovery. mashing the volume up doesnt work, and neither does adp. just to check I used my working CWM img, but i cant reboot into that recovery either.

once I can figure out what this issue is, I should be able to flash your rom without any errors (those ones before were cause by the lack of a kernel which I fixed)

thank you very much for all the help
[Xperia Z2 Tablet General] kulvertti:
Your are welcome. There are two kinds of files. Flashable via recovery and installable via pc. Choose installer version and you find install.bat in it.
[Xperia Z2 Tablet General] joeyishar:
it says that the zip file cannot be opened because it is invalid

idk if its useful, but here is the mht of the issue

edit: woops, that mht doesnt show the error.

its says:

windows cannot open the folder.

The compressed (zipped) Folder 'Ç:\Users\Joey\Desktop\demo box\TabZ2-lockeddualrecovery2.8.15-RELEASE.installer.zip' is invalid
[Xperia Z2 Tablet General] kulvertti:

i got the some error when I used easy root tool

all times it went through, but when tested (either by the program or by me) it didnt work

do I need to install something else on my computer? is towelroot something I need to install?
[Xperia Z2 Tablet General] kulvertti:
Are you by any chance trying to root Lollipop firmware? Latest rootable firmware for this device is .314 (KitKat 4.4.2) firmare. Download it here: https://mega.co.nz/#!kcxxjaLA!itErjRi2fYPPswal-c7XasF_lAvPKyY4GwEzY3xgHZ0 and flash with flashtool. Then try to root it again.

[Xperia Z2 Tablet General] kulvertti:
It is downgradeable. Maybe bad download. Download again and try flash with Flashtool. If no luck send Flashtool log here so we can see what happens.
[Xperia Z2 Tablet General] SANGER_A2:
How well does this rom work? I'm considering upgrading. I'm running the latest rooted kitkat rom and it's great. How is battery life with lollipop? Are there any apps or stock features that don't work? Thanks. Very much.
[Xperia Z2 Tablet General] rockknee:
Is possible to install this on top of cm12.1 with TWRP? Ofc data/cache/system wipe first...
[Xperia Z2 Tablet General] kulvertti:
It's working very well. Battery life is good. All stock features work. Xposed ain't stable yet and some modules don't work with LP but other than that no major problems with apps.
[Xperia Z2 Tablet General] kulvertti:
With clean install yes.
[Xperia Z2 Tablet General] SANGER_A2:
Works brilliantly for me. I used titanium backup to transfer all my apps with their data across to it. Thanks again kulvertti.

will this work with the verizon z2? I no longer have verizon but i still have the tablet, so i do not care if mobile data works just Wifi. if not is there any way to root and get custom recovery on my device. any info appreciated. thanks
[Xperia Z2 Tablet General] kulvertti:
This is interesting. Obviously I can´t test this myself but it should work if you don´t mind mobile data. If you do care mobile data instead of this I would flash my friend [MENTION=3577628]Bird40[/MENTION] prerooted firmware from here http://xdaforums.com/xperia-z2-tablet/general/prerooted-zipcustomized-ncb-t3100783.

And if after that your mobile data don´t work there is this thread http://xdaforums.com/crossdevice-dev/sony/thread-progress-please-leave-im-updating-t2871269 which should help you to have working mobile data with verizon also. Please report back how it go. For rooting I still think best way is downgrading to 4.4.2 firmware if you are any higher and using easy root tool, dualrecovery... etc. There is this http://xdaforums.com/android/apps-games/one-click-root-tool-android-2-x-5-0-t3107461

but it won´t give you proper root and there is some security questions with it. Good luck.

Op updated and added new .291 firmware. It´s been about week that Z2 series updates begin but there is no update for SGP511. Because of that I´v been using SGP512 firmware and thought that you might want to do the same as it works just fine in SGP511 devices as well. It show "Model number" SGP512 in "about tablet" screen but that is easy to fix by editing build.prop -file in /system folder.

Hope you like this.
[Xperia Z2 Tablet General] lazyNeighbour:
Hey, I just did update to .291 on my SGP511, but i've got bootloop. It won't pass purple xperia waves animation. I did wipe cache, and after that I did factory reset, but it didn't help. Is it safe to apply same bootloop fix as with previous fw?
[Xperia Z2 Tablet General] kulvertti:
Yes it is. Or you can use Flashtool fix. Instructions are post #256.
[Xperia Z2 Tablet General] myeepad:
Yap, the bootloop was there but I install the bootloop fix zip and it worked like a charm.
[Xperia Z2 Tablet General] ciarpame:
Flashtool fix should work for SGP521 too and it's the best approach because it will not overwrite modem and firmware meant for another device, am I right?

Thanks
[Xperia Z2 Tablet General] kulvertti:
Yes, you are right.
[Xperia Z2 Tablet General] sofir786:
Is this rooted like the previous firmware you created? Have you noticed any differences at all, I'm running the previous 6.0.1 build
[Xperia Z2 Tablet General] kulvertti:
Yes this is rooted and TWRP included. Don't have official changelog but there are differences. Try it and if you don't like it you can always go back to previous version.
[Xperia Z2 Tablet General] kulvertti:
It's okay. If you need help just pm me. Perhaps we could figure it out.
[Xperia Z2 Tablet General] Irieone:
I make it through boot and to the opening screen where you chose your language. The moment I touch the screen, the tablet reboots. I can't access recovery either. Any thoughts?
[Xperia Z2 Tablet General] kulvertti:
Sorry to hear. The recovery thing is wierd. Without more info I can only suggest that you go here: http://xdaforums.com/z3/general/wip-sony-android-6-0-mm-t3337357 and install recroot with pc for your device. About bootloop see post #256 how to fix it.
[Xperia Z2 Tablet General] Irieone:
Yes, I tried the bootloop fix (post 256) and it don't help.
[Xperia Z2 Tablet General] kulvertti:
Hmm. Maybe more info so maybe I can help. Which ROM you came? UB or LB? Wipes? Your custom recovery? For bootloop do you try Flashtool fix or flashable.zip file fix?

I PM'd you so as not to highjack your thread.

Hi,

just a quick one. I am on stock 6.0.1 (32gb) with no root, no twrp. Can I just flash it via Flashtool and is it gonna work?

Ta
[Xperia Z2 Tablet General] kulvertti:
Sorry but nope. You need custom recovery (TWRP).
[Xperia Z2 Tablet General] MrMagic:
Question about getting into recovery on MM:

I was on a non-rooted .575 ROM and was able to activate TWRP recovery using danalec's guide here.

From this TWRP I flashed your .291 ZIP without issues. However, I cannot get into recovery by booting with vol down pressed. Am I doing something wrong? Root is still active.
[Xperia Z2 Tablet General] rybaryba33:
volume up?
[Xperia Z2 Tablet General] MrMagic:
Nope... With volume up pressed the tablet won't even turn on...
[Xperia Z2 Tablet General] kulvertti:
To go custom recovery boot up and in Sony logo when seeing green led push vol down until led turn purple. If you don't see green led you are most likely installed another busybox which are incompatible with recovery. Uninstall that and run recroot via pc is the easiest way to fix that.
[Xperia Z2 Tablet General] MrMagic:
Awesome, that was the trick!

I was turning on the tablet with vol down pressed instead of waiting for the green light, but apparently Sony is a little bit different than other brands :D
[Xperia Z2 Tablet General] dex9mm:
Ok so I've been having issues with the updates so far everytime I flash I lose supersu for some reason it seems to be still there I just install from playstore and install binary through the app it's self

Now I seem to be getting random restarts and when I plug in to charge it reboots I'm coming from a completely clean install just with xposed and the drm restoration mod from the crossdevice section

Update just lost recovery and rom bit of a soft brick from a system wipe no booting beyond the Sony logo

Flashed ftf through flashtool

Back to working state

But I need a recovery zip of you have one handy

I can't seem to find twrp for this device

Im on an unlocked bootloader and yet I seem to not be able to flash a recovery

Also how do I properly install the recovery

"Fastboot flash recovery 'nameofzip.zip'" is this the correct command via the pc or should I be using adb instead

Sorted now with a ftf, 291 and the root recover in the other post I'd like to know how I can install twrp the regular way instead of having to ftf all the time

getting bootloops on latest build..is theer a fix for that

edit

the previous bootloop fix worked
[Xperia Z2 Tablet General] CAL7:
I'm having (new with the .291 release) issues with the old "write external sd card" problem.

As an example, Titanium Backup sees, as in it reads fine, the card but will not write. So, I pulled out SDFIX by NextApp but it complained there was no "WRITE_EXTERNAL_STORAGE" permission field. I then looked at platform.xml to verify that is indeed true. There is WRITE_MEDIA_STORAGE, but no WRITE_EXTERNAL_STORAGE. I added in the permission (same way as since this problem began at Kit Kat time). Now SDFIX sees all that and says the fix is already in place.

AFAIK, I have all the pieces in place for apps to write to the external SD, but it didn't work. Ideas, please?
[Xperia Z2 Tablet General] athua:
Have you tried installing Xposed and then using the Marshmallow SDFix module? I don't think the SDFix app by NextApp works with Marshmallow.

http://repo.xposed.info/module/com.balamurugan.marshmallowsdfix
[Xperia Z2 Tablet General] CAL7:
Thanks. I had not realized sdfix has been outmoded in MM. I did install the Xposed module, and everything I've tested so far works except for Titanium Backup. TB still won't write to the external card. Other ideas?
[Xperia Z2 Tablet General] thunder141:
You can create a New folder within tb. Choose document provider and then external card and then create folder. You can move old backups to that folder

OK I've been gone a long time and still on 5.0.2 or something like the 23.1.A.1.28 update over year ago or more. I normally made my own prerooted firmwares with prfcreator xperifirm flashtool and such but always double checked against your build to be sure.

As it stands now I have the old .28 firmware rooted and xposed on my tablet. At this point can I just install this rooted 6.0.1 firmware? Or do I need to start over from scratch? Or something else?

Sorry for the questions and I'm sure this has probably been asked and answered but my brain started hurting trying to keep all the information straight.

I appreciate any help I can get. Thanks
[Xperia Z2 Tablet General] kulvertti:
Your xposed might not be compatible with newer firmware but other than that you are good to go. Wipes are recommended and check post #256 how to handle bootloop if it happens. I don't have it but some are reporting it happened to them.
[Xperia Z2 Tablet General] saf4xdadev:
So I should uninstall xposed first? Then I can just load your prerooted firmware? Would it help to do a factory reset first.....if it's even possible....would I do it from the settings/backup & reset/factory reset data?? or is there some other way or is it not even needed?

When you say wipes are recommended, you do mean dalvik and cache wipe after the update while still in the recovery menu?

Just to be clear......you actually used the sgp512 update to make this prerooted firmware? So it really is a legitimate sgp512 even though your device is sgp511?

Also, I just used XperiFirm_5.0.0 to download the latest sgp512 and it's still the 23.5.A.1.291 / R2D release, this is the same .291 as yours still, right??

Thanks again, sorry for the long writes, and I hope you don't mind if I ask more questions again later as I still want to make my own prerooted firmware to install on my z2......just my ocd, sorry.
[Xperia Z2 Tablet General] kulvertti:
No need to uninstall xposed as flashing this will overwrite it anyway. With wipes I mean factory reset with TWRP. Wipe system, data, cache and dalvik/art cache. I personally still use this even there is .291 firmware for sgp511 too, working just fine and is the latest possible. No need to be sorry for anything. I'm glad if I can help.
[Xperia Z2 Tablet General] sofir786:
I just received a firmware update notification on my wifi only tablet (511), I'm currently on the previous mm firmware that was posted (.575). Not sure what the build number is as it doesn't say, holding off updating as I know I'll lose root probably even though it says I won't lose any data urgh.
[Xperia Z2 Tablet General] saf4xdadev:
Thanks for the great help.

Does xposed work on this firmware? or does it need updating? or not at all?

Can you help me make my own prerooted firmware, I know a whole lot has changed since the last time I made one way back on 23.1.A.1.28 plus I found 23.4.A.1.232 on my computer I made later but got lazy and never installed.

So its been a while.......anyway, I already used XperiFirm_5.0.0 to download update 23.5.A.1.291_R2D.

Using FlashTool64-0.9.19.8 I see a whole lot more .ta files now than last time, so I assume I exclude all of them still? Anything else different with flashtool now compared to back then?

I also got UPDATE-SuperSU-v2.76-20160630161323 and TabZ2-lockeddualrecovery2.8.26-RELEASE.combined which I see now you are just using TWRP so has something changed?

At this point I would assume I'm good to go, use PRFCreator_v1.3 and it's done, but I don't think it's that easy now. I've read on here something about dummy files and different su or something more that needs to be done???

Am I close? Thanks again.
[Xperia Z2 Tablet General] pixbuf:
I realize the answer to this question may not exist outside Sony's walls but....

I installed the .291 firmware (thanks, Kulvertti!) and noticed that the Android security patch level is dated May 1, and that the tablet is still vulnerable to CVE-2016-2059 and CVE-2016-2504. My phone has the August security patch, and is not vulnerable to those CVE's.

Anyone know when the security patch level will be brought up to date?
[Xperia Z2 Tablet General] sofir786:
The z2 is almost 2 generations behind sonys latest tablets, eventually they'll stop doing updates, we may never get another update saying that.
[Xperia Z2 Tablet General] kulvertti:
You need to update your xposed. After that it works just fine.

For your own prerooted firmware you need .291 ftf file, RecRoot and fake SuperSU. Last one you can use this which is just empty file https://mega.nz/#!ZEAnDQLQ!23AD-mnilnUO_bg1UND0gcWfIMjqK00BLPCo0ETESEE

Exclude all .ta files, put fake SuperSU to its place and RecRoot to Recovery place and you are good to go. As RecRoot install TWRP, SuperSU Busybox etc we need to use fake SuperSU. DualRecovery is not compatible with .291 firmware at the moment.
[Xperia Z2 Tablet General] saf4xdadev:
Thanks for this kulvertti. I just reread through this entire thread and links and downloads and came to the same method.......but thanks for confirming because I was having hard time going through with it until I heard back from you.
[Xperia Z2 Tablet General] saf4xdadev:
Ok this worked....yeeha! Thanks kulvertti for the help. I made one and got it all installed and my sgp512-US seems to be running as expected. I'll have to setup the apps again but I didn't have that much to begin.

It was having a little trouble finding the internet, could be problem on my end, but it connected to my wifi fine but couldn't get out to web. It tried and tried, so much so I gave up resetting things and just left it and finally all of the sudden it found it.

Couple other things though.....

I used your dummy SuperSu but I used v4 of RecRoot and I think your thread linked v3........anyway it worked but I only have v2.71 of SuperSu and not 2.76 per the OP. Did I do something wrong? or do I just need to update it now by flashing the 2.76 zip with twrp?

Also, I seem to still have files in my Download folder.....is that possible? I wiped everything before I installed the update. Shouldn't that all have been deleted or overwritten? I sort of glad because I missed copying it over to the external micro-sdcard....but I'm baffled???

Xposed is next.

Thanks again.
[Xperia Z2 Tablet General] kulvertti:
Just flash latest SuperSU with TWRP. If you don't wipe internal storage that is expected you have download folder untouched.
