[WIP][KERNEL] Stock kernel from 10.1.1.A.1.253

DISCLAIMER: USE IT AT YOUR OWN RISK
First of all, thanks to DoomLord for helping me to learn how compile kernels in the XZ. And for the toolchains and for everything pretty much.
Secondly, this is the first kernel I've compiled, I haven't modified any files from it so it should be 100% stock. I also haven't had to chance to test it yet, so report if it works, or if it doesn't
I've managed to compile the new kernel for the xz using the latest source from sony
Information:
For stock rom, unlocked bootloader.
Compiled using arm-eabi-linaro-4.6.2.

Kernel Source: Sony link
Toolchains: Github link
Credits:
DoomLord for letting me use his build_tools, toolchains, recovery installer and overall for all his help.
Enjoy

So, is this COMPILED (self-made) or STOCK ROM? I don't think they can be both (unless you have some sort of "keys").
I'm asking because I really want the BRAVIA engine still working.

It's a compiled kernel from stock sources for unlocked bootloader.

I'm confused. Will this help me get root?
Or rather, can you help me out here. I am right now on .434, rooted C6602.
How can i flash 253 and still keep root? Do I use flashtool, and flash everything except the kernel?

No, wait until I upload the version 3 of my stock rom, then flash it through cwm/twrp. Once you have done that, you have to flash kernel, baseband, fota from the ftf using flashtool.

Is a recovery included?

In the kernel no.

This may sound like a stupid question but why can't we just pull the boot.img from people who installed the rom using Sony update service?:silly:

hehehe, because when you update your phone through sus you lose root so you can't dump the partition?

Sorry for the question but I can't understand:
I flashed the new firmware (253) now I have kernel version 3.4.0 do I have to flash this kernel too? Or it was included in the ROM flash?

This is only for unlocked bootloader. If you installed the kernel from ftf .253. You don't really need to.

Man I made a mess I'm so depressed
I flashed the kernel but I get a bootloop so i flashed the full tft firmware and now I have updated firm and kernel but there's no way to root it. All methods doesn't work for example fastboot and no recovery of course so I'm stuck I'm thinking about downgrade and root again and try to update

Just flash .434 tft but only system partition, don't wipe anything. Root + install recovery. then flash my rom through recovery and you will be fine.

After many hours of work I finally did it. I have firm and kernel updated and root. I don't really know how I made it, after many hours of flashing every zip or ftf on the forum I'm confused and I just want to forget everything now It's better to go out and take a walk.
Thanks for all.

Root Guide For 4.2.2

All credit goes to @zhuhang. I have no contribution to it.
Original thread is here: http://forum.xda-developers.com/showthread.php?p=45344021
This method will help you gain root access on the latest .67 4.2.2 update that Sony recently pushed out.
Disclaimer:
- This requires a PC.
- No CWM needed.
- This installs a Chinese root manager rather than superuser or superSU. But I will teach you how to replace it below.
Instruction:
1. Download the rooting application. (This app can root many other devices )
VRoot_1.6.0.3690
http://www.mediafire.com/download/v3...3690_Setup.exe
2. Install the app. This is a Chinese app so I will guide you. Below is a step by step screenshot attached guide.
3. Start VROOT and root now!
4. Now we need to install SuperSU from play store to replace the Chinese root manager called 授权管理 1.0.4.
5. Go to play store and install SuperSU.
6. Start SuperSU and you will be asked for permission by 授权管理 1.0.4, choose 允许(means allow). (Should be the right side option.)
7. SuperSU will prompt to install SU binary, go ahead with OK and it will display successful.
8. Now, freeze 授权管理 1.0.4 in titanium backup, just in case you need it again.
Note: If you uninstall straight away from app manager, you need to make sure SuperSU updated the binary.
9. Re-run SuperSU to make sure everything is alright. You will be prompt again to install SU binary, just do what it asked.
10. After that, you are rooted with SuperSU and 授权管理 1.0.4 will not be there anymore.

Can someone upload an ftf with just the kernel.sin and bootloader.sin for the C5503? I tried creating one using C5502 kernel and i got stuck in a boot loop. luckily my battery was just at about 10% and so I quickly flashed back the 4.2.2 Kernel of the 5503 and all is well.
Once we get the kernel only ftf, can test and create guide for rooting 5503 on 4.2.2

Tried with the C5503 kernel. Same boot loop. I think we'll have to find an alternate root method, as unlike the Z, the ZR doesnt have .234 firmware [that is also 4.2]
Experimenting with the Z firmware. Wish me luck

Why not flash only kernel from the previous firmware? Isn't working?
UPD. I see - not work

I have rooted mine already (ie. Android 4.2.2). You have to unlock your bootloader for this method to work.

Firstly you need to unlock your bootloader. Google that, its easy. OR you can do it through flashtools (not tested).
Enable USB Debugging and unknown sources option on your phone before proceeding.
Download Flashtool, Open it. Flash the the kernel of an old firmware of Xperia ZR which was rootable.
Reboot your Xperia ZR after flashing. Connect to PC in USB Debugging mode.
Do not forget to close FLASHTOOL.
Extract the downloaded “DooMLoRD_Easy-Rooting-Toolkit_v18_perf-event-exploit.zip” file and run the “runme_win” file.
Follow onscreen instructions to root Xperia ZR and once it is rooted, device will reboot. Verify that you are rooted, run SuperSU app.
Now switch off your Xperia ZR. OPEN FLASHTOOL.
Now you need to flash the true kernel of Android 4.2.2 10.3.1.A.0.244 firmware of Xperia ZR.
After flashing, disconnect the phone from PC, reboot it and your Xperia ZR is now rooted

So basically you're doing:
Use FlashTool to flash the 4.2.2 FTF
Downgrade the kernel by using FlashTool back to 4.1.2
Run the DoomLord rooting kit
Flash back 4.2.2 kernel using FlashTool
To flash the kernel you need an unlocked bootloader. What I don't understand is how to flash the kernel only? I found the kernel.sin inside the FTF file. Can I just delete other .sin file and flash the remaining FTF file?
Sorry if my questions are noob.

You need to keep the kernel.sin and bootloader.sin in the ftf and delete the rest. Also don't delete the META-INF file.

The problem is the bootloader? I thought doom's thread said that this was for locked and unlocked bootloader. Unlocking the bootloader will lead to a lot of people avoiding the root method.

So is an unlocked bootloader NEEDED for this method to work for ZR? I thought DoomLord said it works for both.

I did manage to root it, but then the phone suddenly restarts. Now I am stuck with bootloops. Strange as I managed to install Superuser from the Play Store.

Yes. I fixed the bootloop issue. Need any help with the bootloop?
If you've got a bootloop, pull the battery asap as once it dies, you won't be able to flash ftf and the device will be bricked.
To fix bootloop [and still not get root access]
1. Open the 4.2.2 ftf file in flashtool.
2. Exclude everything [tick in the exclude box] except the kernel, and untick everything in the wipe box [data, applog]
3. Flash the kernel by pressing the volume down button while plugging in USB cable [DONT PRESS POWER BUTTON AFTER BATTERY PULL AS OTHERWISE YOU'LL GO BACK INTO BOOTLOOP]
4. After it flashes [should take a couple of seconds], reboot and you should be back to normal
I REPEAT PULL THE BATTERY IF IN A BOOTLOOP OR YOU'LL LAND UP WITH ANOTHER PAPERWEIGHT

So again you're not successful in rooting 4.2.2 using the kernel switching method?

i think the kernel switching fix will not work on ZR.. we don't have a rootable 4.2 kernel
i think the 423 kernel is 4.2

It happened to me also, but it's possible to recover from it.
Install PC Companion on your PC.
Go to Support Zone.
First option -> Update phone / tablet software.
You will see a underlined link that says "repair phone / tablet"
Just follow the instructions.
You will need your phone to have at least 50% battery level. Take out the battery, insert again, and connect your phone to your PC via USB while pressing the Volume + button. You will hear a sound coming from your PC meaning it's been connected.
Sony PC Companion then will flash your phone with the latest firmware. It takes a while and you need to have internet connection, but it works.
As you flashed the Russian system rom, the firmware installed in your phone by Sony PC companion will be the Russian Android 4.2.2. No problem with this as it includes all the languages.
Do this as soon as possible as you need your battery charged and you can't charge the battery in your phone while in the bootloop state.
-------------------------------------------------------------------------
-------------------------------------------------------------------------
I'm not sure what we did wrong to be stuck in a bootloop, but after my ZR being reflashed by Sony PC Companion I just flashed the Nordic 4.2.2 ROM and my phone remains unrooted until there is a easier method to get root

In fact you should read the other thread for a workable root method for 4.2.2. This thread is very old and AFAIK this method doesn't work.

[Q] Rooting Sony Xperia Z .244

Hi fellow mates,
Recently I have updated my Sony Xperia Z (Singapore) 10.3.A.0.423 to 10.3.1.A.0.244 and I was previously rooted on 10.3.A.0.423. So after updating the phone, I followed Doom'sLord method which is:
[ how-to ]
Download the three files from the download section below
open FlashTool and flash the XperiaZ_C660X_KernelOnly_10.3.A.0.423_Generic_NL.f tf - 7.12 MB file, this is JUST the kernel of an older firmware which was rootable
now once flashing is done reboot device and connect to PC in usb debuggin mode
CLOSE FLASHTOOL <<< VVVIMP STEP
extract the file DooMLoRD_Easy-Rooting-Toolkit_v18_perf-event-exploit.zip to root directory on c:\
execute runme_ file corresponding to your OS on desktop PC, this will execute a SPECIAL version of my easy rooting toolkit <<< VVVIMP STEP
the above step is crucial! if you use any older version of the toolkit then IT WILL NOT WORK!
after rooting is over the device will restart
you can verify if device is rooted by checking for SuperSU app (it is the newest version)
once thats done now power down device and open FlashTool again
now flash XperiaZ_C660X_KernelOnly_10.3.1.A.0.244_BE.ftf - 7.17 MB file to get back to the true kernel for the firmware
thats it after flashing is done just disconnect and power on device and enjoy rooted phone!
Click to expand...
Click to collapse
After which, when I switch my phone on to check if it's root. It seems that it has not been rooted and no super user was installed. Can anyone help me what is the problem? I had USB DEBUGGING turned on, Unknown Sources turned on as well. Latest flashtool 0.9.11.0 installed, latest Doomlord v18 easy rooting toolkit. But still couldn't find whats the issue. Looking forward for help. Thank You
Regards,
Gabriel

@XperienceD
As you had mention, I did follow that 2 steps. After which I had to go to applications and find the Superuser applications, and hit the uninstall button. After that, it was rooted once again. Superuser icon came up, asking for permissions like the usual. Something is wrong even though it's already been rooting. But thanks for the advise. Will bare in mind the next time an update is up. Thanks alot!

Hello, I've tried flashing back to the old firmware from the latest, but it's saying my phone needs to be in usb debug and allow unknown sources, these are both allowed ? im not sure what I can do.

Xperia Z .244 firmware charge issue
Hello all,
I am facing this weird issue with my Xperia Z rooting. I am on .244 baseband but when I tried changing it to the .423 using the flashtool, it didn't change. I tried several times but same results. Thus when I try rooting my phone the script showed not compatible.
Please let me know what can be the problem? Do I compulsorily have to be unlocked for this to work?

facing a problem too, I can not seem to even flash the .423 kernel in flashtool. I keep getting an error saying to make sure debugging in on etc.. And have both debugging and mock locations turned on?? Weird because I have flashed firmwares before on this device.

Is the phone turned OFF and connected in flashmode?
If so, make sure you're using the latest version of flashtool.
www.flashtool.net
If you already have the latest version, try reinstalling it.

Just to make sure you have everything setup properly and are following the correct procedure, follow this tutorial for using flashtool - How to flash stock roms with Flashtool
If that doesn't help, I'm not sure what the problem is.

Yes as far as I can tell to the letter? I have flashed firmwares before so I'm lost. I have noticed after a failed attempt I lose wifi.
Im downloading the stock .244 ftf and will try to flash that, I'm not sure if I can just flash an older firmware or not.
Thanks again for your help so far

Edit: after more investigation my phone was actually on .423 but still showing .422 under settings. All good now and rooted

[Q] Help How to flash stock rom

Guys please help
I flashed a custom rom and it got a lil messed up..
I've downloaded an ftf file but I have no idea on how to flash it.
I havent made any backup,my bad.
I'm using C5302

If you look a bit futher you will see a easy guide made by me about how to get back to stock without the use of flash tool

You have to download flashtool to flash an ftf file if you don't have any backup you lose your data but once you flash the ftf you're going to be fine

If you haven't unlocked your bootloader you can also use Sony's update service (SUS) to restore your phone.

if you can get into flash mode just flash a clean fw using flashtools, preferebly .534 so you can root...

Go to c:\flashtool\firmwares\ and delete "prepared" folder. - That's only firmware files prepared every time for flashing.
Restart your PC and open flashtool (right click and open it as administrator.
Make sure you have at least 1Gb of free space on your disk where's flashtool is located.
