Xperia Tablet Z2 (SGP521) bootloop - Xperia Z2 Tablet Q&A, Help & Troubleshooting

Hi.
I own a tablet Xperia Z2 (SGP521) with Android 6.0 with root, and I tried to install the "Z2-lockeddualrecovery2.8.26-RELEASE.combined.zip" file, but after I installed the file via "install.bat", I discovered that which I installed it wrong, but instead I had to install the file "TabZ2-lockeddualrecovery2.8.26-RELEASE.combined.zip".
And now my tablet keeps rebooting, how can I fix it?
Thanks in advance.
And I apologize for my English.

I solved the problem by itself, through Sony PC Companion.

Try this way:
Downgrad to 4.4.2 via ftf-file
root your tablet
install "Z2-lockeddualrecovery2.8.26-RELEASE.combined.zip" via install.bat from PC
After reboot in TWRP, do a factory reset and rebboot new in TWRP
Then install a new prerooted zip.file (***.575) via TWRP
My SGP521 work.... without bootloop...

Then i tired to go into flashmode but when i connect it to pc green led shows out and after 2 or 3 sec. red light shows out and it just boots again into Sony logo. Please help somebody I just need to get into flashmode and then i can flash .tft with Flashtool. My phone is from O2 carrier (but unlocked all sim cards work) bootloader is locked.

Have you installed drivers correctly? What operative system do you have in your computer?
If you have not, go to C:/flashtool/drivers and intall them (you have to check your device and 2 last options in the installer (fastboot and flashmode)

I'm sorry that's all my knowledge for now, hope someone else in here can help you with this. If I were you, I'd try installing flashtool and drivers from scratch on another PC.

Whatever Anyway thanks for help. I'm going to leave my phone turned on all night so it will totaly discharge and then i will try to charge it and put into flashmode. Maybe this will work. I'll post the results if i'll fix my xp.
Phone is working!
When i tried discharging phone, that didn't help so i gave my phone to my friends dad because he is a good phone technican, and fixer. So what he did? That was akward moment :laugh:
1. When he conected phone to his pc (win xp) the computer detected my phone (my computer wasn't able to detect)
2. Then he just flashed some files. But not with Flashtool. He used program called SE2tools or something like that.
3. The phone booted up and now is working sucessfully

I think it was a driver problem after all. Next time if you have this problem again, even if you have already installed the drivers, try uninstalling and installing again... Windows is crazy , especially win8 which I'm hating more everyday lol

If you're boot loader is lockes you can use SUS then create the FTF file to flash with flashtool next time you need it.
If it's unlocked, use PCC to repair until the stage it ask you to connect the phonem then build the firmware FTF to flash with flashtool.

Placed the ROM.zip in sd card and did a full wipe. In my CWM, there is no option to go back, hence rebooted the system to install the ROM after full wipe. My phone got stuck at Sony logo and even unable to access CWM. Please help!
I did the following steps mentioned in the ROM page of XDA to install the custom ROM on my phone.
1. Flash boot.img from .zip via Fastboot ---- LEFT OUT THIS ONLY STEP BY MISTAKE and done the subsequent steps.
2. Enter CWM
3. Make a full wipe:
4. Wipe Data/Factory Reset
5. Wipe Cache
6. Wipe Dalvik Cache
7. format /data (advanced)

9. format /system (advanced)
-Flash ROM. --- YET TO FLASH THE ROM.
I'm unable to access CWM. I can't power off, I can only restart, but getting stuck at Sony logo everytime.

Dude your a bit confused.
The only thing you may need flashtoo is first step (Flash boot.img from .zip via Fastboot ) all the rest is done in CWM recovery.
I don't know who told you to drain your baterry, but do not ever flash anything with baterry less than 50 percent, prefferrably fully charged.
Flash stock first, copy the zip to your SD card, then follow steps 1-9+.
For step 1 you need to extract boot.img from the rom zip on your pc.
To enter CWM recovery (after you flashed the boot.img), while device is booting (Sony LOGO) press volume down every second or so untill you are in CWM.
To nevigate in CWM, select - home key or power, move down - volume down or menu key, move up - volume up, exit/return to previous menu - back key or select at the bottom of the menu.
Stuck at Sony logo!

No No bro listen, I did a mistake while installing the Custom ROM.
I forgot to flash the boot.img and did full wipe even formatted the system. Rebooted the system without installing the ROM. Now, stuck at Sony Logo. (NOTE: During this I had the battery charged full)
To rectify the above issue, I tried to flash the boot.img through fastboot mode in Flashtool and install the Custom ROM through CWM. To connect to flashtool, the device should be switched off. Now, I cant switch off. I can only restart. Hence, I drained the battery completely and tried to connect to Flashtool. When I hold Volume Up key and connect to PC through USB, only red LED lights up. It is not connecting to Fastboot mode, also when holding Volume Down key and connect to PC through USB, only red LED lights up. It is not connecting to Flashmode.
Please help!

No you do not need to drain the baterry, nor do you need to shut down the phone.
In the link you have provided it shows you how to boot into fastboot via adb (Click 4).
Recharge your phone and follow the steps given there.

Turn the phone off, no need to drain battery, just press power + volume up until you feel 1 + 3 vibrations, open flashtool and connect in fastboot mode (volume up while connecting USB)
Do you see device connected in fasboot mode in flashtool log?
Did you install fastboot drivers from flashtool?
What is you windows version?
Got it Worked!

What do you mean by "PV won't detect the phone?".
It cannot be dected like it does usually.
The phone must be turned off (press power + volume up untill you feel (1+) 3 vibrations. Then you should be able to flash in flash mode, either with PC Companion or flashtool.
even i got my xperia p screwed there is no custom recovery no os what to do ? please help me

then boot your phone in custom recovery mod and click boot in flash mode.then connect your phone to the pc then download the firmware for your phone .Then open flashtool and click the flash icon on the top and select the firmware and click flash a
and the phone will be ready to use .
hope this will help
Maybe flash ftf file with flashtool can fix it?
i always use flashtool when i met your problem,i think it would help you

Unable to access bootloader

Yesterday I tried to flash a a new rom on my Xperia Z2 (unlocked bootloader).
From TWRP I did an advanced wipe and selected basically everything except my mircoSD (because it has the new files).
After a long time of waiting I tried to flash the ZIP file and it gave me an error. I thought this had to do with the wipe so I decided to reboot my phone.
As you can imagine, it got stuck on the Sony logo (because system would be empty).
From this moment I couldn't do anything with my phone, except from the tool Emma.
I now have some clean installation of Sony their Android 6.0.1 for the Z2 (23.5.A.0.570) but Im unable to flash TWRP through fastboot.
The command adb devices shows my phone, fastboot devices gives an empty response.
When I restart to the bootloader from adb and try to flash TWRP I get the message "< waiting for device >".
I tried on three different PCs including a clean install of Windows with all kind of different drivers, yet I cant get fastboot to work.
Am I stuck with this unrooted version of Android now or do you guys have any suggestions for me?
Thanks in advance!

As I said I've tried all kind of different drivers (Android tools, Sony drivers and flahstool drivers). So for me it's hard to tell what I'm doing wrong.
My computer notices the phone (if I hold volume up and attach the charger), it just doesn't show up under fastboot devices.

Okay, apparently it was because of the driver signature stuff in Windows 10.. The fastboot command now works fine!
Next problem occurred though, flashed the newest TWRP recovery but as soon as I enter "adb reboot recovery" my phone just normally boots again..
Why do things never work out the right way for me as they are intended..

Okay, apparently it was because of the driver signature stuff in Windows 10.. The fastboot command now works fine!
Next problem occurred though, flashed the newest TWRP recovery but as soon as I enter "adb reboot recovery" my phone just normally boots again..
Why do things never work out the right way for me as they are intended..

Manually boot into recovery by booting up your device normally and when you see a violet LED, press vol+.

Tried:

- reset with Pwr+VolUp (three vibrations)
-Connect cellphone to laptop and access to recovery mode throught adb reboot recovery but device isn't found
