Bootloop after reflashing stock kernel (32.2.A.0.253_1298-1220_R2C kernel) - Xperia Z5 Compact Q&A, Help & Troubleshooting

Hello to the community,
I need to revert to stock kernel on my Sony Xperia Z5 compact ("formfactor" E5823). So I thought flashing the stock kernel which I extracted from the corresponding ".tft"-file will do that. So I flashed the extracted ".elf"-file with flashtool. But after restart I get stuck with the boot logo of Android "Marshmallow".
To avoid further questions I'll describe what I've done to root my device after unlocking the bootloader:
ROOTING:
- I downloaded a ".tft"-file containing Android 6 (32.2.A.0.253 build 1298-1220 R2C) and saved it to my hard disk
- I installed this ".tft" on my Sony Xperia Z5 compact using Flashtool (version 0.9.22.3)
- I opened the ".tft" from my hard disk and extracted the "kernel.sin"
- With Flashtool (version 0.9.22.3) I extracted "kernel.elf" from the ".sin" file
- I rooted the ".elf" using rootkernel (version 5 RC4), using the Options Sony RIC disabled, dm verity disabled, installing SuperSU 2.79, TWRP and DRM-Fix and saved the result to "kernel_rooted.elf"
- I flashed that rooted kernel using Flashtool (version 0.9.22.3) without error
- After rebooting the system was running rooted and without stucking in a boot loop
UNROOTING:
- I flashed the unrooted kernel "kernel.elf" using Flashtool (version 0.9.23.1)
- After rebooting the system get stuck in a bootloop showing the Marshmallow boot logo
And this is what I don't understand:
I use an unmodified stock kernel and get stuck in a boot loop. Another strange thing is that when flashing other rooted kernels (using updated tools rootkernel (version 5.23) and Flashtool (version 0.9.32.1)); for example just with TWRP installed) I get stuck in boot loops, too. The only working kernel is that one I described above.
Can someone tell me what I'm doing wrong?
Thanks for help and greetings from Germany

Not sure if this will help, but did you wipe the cache and dalvik cache?

[ROOT] Root/Install TWRP Sony Xperia M4 Aqua E2303 LB on 26.1.A.2.167/26.1.A.3.92

Root the M4 Aqua E2303 Locked Bootloader/Install TWRP on 2.167/3.92
Before we begin:
Make sure you have the following:
•A Windows PC
•Flashtool (https://drive.google.com/file/d/0B_d8uWGbkaetTnhWX0J5UG5hN28/view?pref=2&pli=1)
•The .128 firmware (https://drive.google.com/file/d/0BzVQf67OZ9NtMFotOXRycTZoSlk/view?pli=1)
•Patience
•A good internet connection
•15 to 20 minutes
• The M4 Aqua Root Toolkit (https://www.dropbox.com/s/edse0h6b02odzn1/rootkitXperia_E23xx.zip?dl=0)
•ADB Drivers (https://drive.google.com/file/d/0B0MKgCbUM0itNVB1elljU2NPR0k/view?pref=2&pli=1)
•TWRP Toolkit (https://www.dropbox.com/s/yomdwq3p2le9hvi/M4Aqua-lockedTWRP-0.1-installer.zip?dl=0)
How are we going to do it:
The procedure is pretty straight forward, as the M4 Aqua is only on Android™ 5.0 we can take the kernel of the older versions of firmwares so we could root the device, while keeping the firmware version to the newest release (2.167/3.92). The method has been only tried on the E2303, there may be chances of it working for the E2306.
Let's begin! Part 1, Changing the Kernel:
First, we need to install the latest Flashtool version (link above), after you proceed with the installation of Flashtool, you need to install the Flashtool drivers, which can be found in C:/Flashtool/drivers or the path you selected flashtool to be installed. Once you open Flashtool drivers you want to select FLASHMODE DRIVERS, this is only so that the M4 will be recognised while in flashmode. After the drivers have been installed, you want to move the downloaded .128 firmware to C:/Users/*YourName*/.flashtool/firmwares or you can use the other method I will show later. Once you have done that you want to open Flashtool and wait for the Sync to finish. After that has finished, you will see a lighting icon in the top-left corner, you want to press the icon and select flashmode, now the second method, at the top you will see a path leading to the generic .tft folder in which Flashtool belives the .ftf files are located by default. You can change that by pressing the button on the right and lead the program to the path of the .128 ftf file. After you have selected your .tft file you will see on the right a lot of options *everything that the .ftf file contains*, if you want to keep the data on your device you can tick the first two options, a bit down on the right you will see a lot of options, including system.bin, you want to tick everything EXCEPT for the kernel.sin, this is the most crucial part. After that is done you want to let the program prepare the files, mean while you want to power off your M4 Aqua, after the process on Flashtool is done you want to press the VOLUME DOWN button while connecting the phone to the PC, once you see the green led light you can leave the button, if everything was done right the process of flashing should begin. If everything went well the kernel should be flashed and the phone should safely power on. Now we can proceed to the second part. Rooting the phone.
2ND METHOD
You can downgrade to .128 firmware and download the .167 or .92 firmware and update everything except for the kernel. You can do this by going into Flashtool, and doing the steps above but TICKING the kernel.sin. Try this if the first method doesn't work.
Part 2, Rooting the phone:
Now that we have changed the kernel we can use the root toolkit to root the device. Download the root toolkit from the link above, but before you do anything you want to go to Settings>About Phone, scroll down to Build number and press it 7 times, after that is done you want to go back to Developer options, and you want to tick USB Debugging, after you have done that you need to install the ADB Drivers from the link above, after that is done you can connect the phone to the computer, now you want to extract the toolkit and run install.bat *No administrator rights needed*, and then you should see a screen on your phone asking if you want to trust the computer, you want to tick the box saying always and you want to press yes, now the rooting process should begin and your phone to be rooted. After this is done we can proceed to the part 3, installing TWRP
Part 3,Installing TWRP:
Now, that we have root we can install TWRP using another toolkit. This part is optional but if you want any custom ROM's you need this. This part is the easiest, you need to download the toolkit from the link above and just run the script. We don't need any additional steps as we did them in Part 2.
If everything went well you should now be rooted and have TWRP with a locked bootloader and on the newest firmware.
In case of bricking you can use the Sony PC Companion tool and repair my phone/ tablet option. YOU WILL LOSE ANY DATA SAVED ON YOUR PHONE.
sir , can this apply to D2353?
I have only tried on E2303, but you use the right .ftf files the procedure should work

Root and flash stock kernel tft u use
I'm having issues with this also. Downgrading the kernel only causes a boot loop animation. I can downgrade everything to 128 and it works. Going back up to latest with everything BUT kernel causes boot animation loops also.
EDIT!
Oh heck yes, I did it! For anyone stuck in a logo boot loop despite following the above, here is how I did it:
- Use Flashtool to completely flash my .167 E2303 to .128.
- Use above tools to root and install TWRP.
- Use Flashtool again, but this time in Fastboot mode. I extracted the system.sin file from a .167 ftf and then flashed system using Flashtool.
- Reboot the phone into TWRP. Clear cache, dalvik. I did NOT clear data.
- Install M4 extras. Install AOSGP. Clear cache, dalvik.
- Reboot took about 15 minutes, probably less.. and BINGO.
Thanks to all.

When i upgraded from 128 to 167, phone works well but random reboots. Any fix this issue?
Clean install of .167 and .92. Flashing the .128 kernel causes the blue boot animation to hang (the start up sound cuts off half way). Flashing the previous kernel back over works.
Same happens when I flash .128 then everything but the kernel from .167 and .92.
Unsure what the FSC script option does, but yes or no makes no difference.

If your random reboots usually happen while downloading or updating apps in the play store, you should try this. Make sure you backup your data first just in case.

Hello,
thank you for this guide. I have a question: why not extracting the old kernel and just flashing the kernel.sin?

Bootloop at startup logo due to XZrecovery getting trashed

Long story - Tried to apply the latest Marshmallow rooted package for D6503 on my 6502 that was already rooted with XZ dual recovery. It installed successfully, was rooted too...but I forgot to add the patch that would fix the radio not working. So I try to reboot to recovery...and that doesn't work anymore. I tried installing TWRP recovery from the manager app, but it wouldn't reboot. Then I ran the XZ recovery installer externally, and now my phone is ****ed. Stuck at an infinite boot loop.
At this stage the only thing I can access is flashtool and fastboot, and since my bootloader is locked I can't flash a recovery that way (nor do I want to permanently lose DRM keys/camera quality as I've heard happens with unlocking the bootloader). I have a memory card and I used the option to disable loading the recovery specified on the XZ thread by adding a 'donotload' file on the sd card.
Still no use - I get a Sony logo for about 5 seconds, the screen goes dark and back to the same. At this point probably my recovery is screwed up or non existent and a bad situation has gone worse with the bootloop.
What can I try now?
@KaiserSnorezay
XZDR is still not compatible with MM, that's why you got a bootloop...
Also you can't install the "regular" TWRP with twrp manager on a LB as there is no recovery partition... it won't work and probably will mess your phone in the process.
The solution is to flash any KK / LP .ftf with flashtool (i would wipe everything when flashing as i have backups of my data/apps) , root it with kingroot or any other method you like, install xzdr for KK/LP and finally reboot to recovery and install the latest MM prerooted rom from niaboc which already has root&recovery (not xzdr btw) included. Since you have D6502 don't forget to install the baseband patch after the rom again
http://forum.xda-developers.com/xperia-z2/development/rom-official-6-0-1-23-5-0-486-beta-t3336770
Just did it exactly this way yesterday on my friends d6503 (minus the d6502 patch obviously) had 0 troubles MM, root and recovery working perfectly.
Thanks, will try this today. Is wiping data required or can i get by by just flashing the older one?

I managed to flash and root 17.1.2.A.0.314, but once again I'm unable to get any damn recovery to work. Installed XZDR, after that TWRP, in both cases it refuses to boot into recovery mode. What am I missing?

Weird, after you have your phone rooted it should be simple to install xzdr... just enable usb debugging in the phone and make sure you have the adb drivers correctly installed in your pc.
Download the latest xzdr from nut's thread ( http://forum.xda-developers.com/showthread.php?t=2261606 ) unzip it and run install.bat . After a successful install the phone should reboot to twrp automatically and it's done.
Okay, I fixed it..using Flashfire! No idea why the recovery didn't work earlier, but now finally I'm on Marshmallow. Thanks for the help!

Although i didnt knew the firmware number , i just flashed with 5.1.1 , 1st with Customized IN & later with of US. Both of them didn't work as well. Please help me out. I'm not much aware about this root stuff & all. hope to get reply soon from you or anyone in this forum.

Try what ptmaniac suggested - flash an older FTF that can be rooted (more recent ones can't), root it, install recovery and then flash the newest build.
You'll have to improve your Google-fu to find a suitable firmware and a root technique for it.

okay. you mean flashing any old firmware ( which i did and still in bootloop ) & root it. Then installing recovery for the same firmware ?
with "recovery" will i be able to get back my whole data ?

"Flash" means installing something to the internal memory.
You need to go back to a "rootable" version and after having your terminal rooted you can flash the latest rooted ROM.
Following the instructions on this thread https://forum.xda-developers.com/xp...lipopprerooted231a128z2-tabletsgp511-t3100821 I suggest you:
Flash the Lollipop 23.1.A.1.28 firmware with Flashtool;
Unlock the bootloader (not sure it is strictly needed but better avoid potential issues) with Flashtool (use the Sony website to get the unlock code as the automatic retrieval of Flashtool did not work for me);
Root using the script mentioned in the thread;
Flash the custom recovery;
Flash the rooted 6.0.1 ROM.

You cant make the root with the flashtool! Copy the SuperSu (download newest zip) on your tablet (anywhere) and proceed with this: "TabZ2-lockeddualrecovery2.8.21-RELEASE.installer" you already downloaded from the tutorial. when you launch the "install.bat", the tablet will be rooted and twrp installed it auto-boot into twrp and now you can isntall your copied supersu zip then you can proceed with the tutorial
Got it fixed. In my first CWM Backup from the Dualrecovery Package (installer) was a working boot.img All fine now!

Bro, use AndroPlusKernel v34 or above as that is compatible with 32.2.A.0.253
Flash ftf, boot.img, recovery.img, boot the Phone till home screen and then Flash SuperSu.
Bootloop Issue could be SuperSU system mode. Any specific reason for Installing SuperSu in system mode??
If some specific apps can't detect root means you can check this Post

Awesome!!
Special thanks for your answer!!
I did below process and success to get root my device.
- download "Z5C_AndroPlusKernel_v34.zip" file below URL
https://kernel.andro.plus/kitakami_r2.html
- unzip that file and use "fastboot flash boot boot.img" command.
Then, I can boot my device.
But, that process couldn't get root yet.
So...
- install "SuperSU-v2.78-201609011115.zip" file in TWRP mode
Then, getting root in my device was success!
Yes but since then encryption doesnt work any more!

The phone shows optimising apps and keeps on restarting

I am newbie to flashing. I thought to install xperia x firmware to my z2 running MM. I somehow unlocked the bootloader using flashtool. Then i couldn't proceed further on how to root., So I downloaded pre- rooted lollipop 5.1.1 from one of xda post and installed it using flashtool.
I just chose the ftf file in flashtool and clicked flash. During installation it asked "Do you want to keep default.fsc" i clicked yes. Now the phone is restarting continously.
The error is get is
"unfortunately com.android.process has stopped working"
and so on and the phone is restarting and showing the same errors.
PL help me..
Even via adb shell i flashed twrp.img and when i click fastboot boot twrp.img an error dtf not found is shown

I would like to know
1)the recover keys for z2. All those power+ repeated press of volume up/down aint working.
2) In adb shell , typing "fastboot flash recovery twrp.img" is finished successfully. but "fastboot boot twrp.img" shows error. "remote dtf not found"
I have searched all kinds of posts for the above problems the whole day and there is not a concrete solution to the above problem.
Pl quote your effective solutions..
