[ROM][STOCK][UPDATE]Xperia Z: DoCoMo ROM 10.1.D.0.343 Update package for keeping root

After releasing ROM update, there’s some people asking about DoCoMo ROM and how to flash ROM version 10.1.D.0.343 with root for locked bootloader. This won’t be a problem for people using custom kernel with recovery support as they can flash root in recovery. However, it’s impossible to get 10.1.D.0.343 rooted with locked bootloader through normal FlashTool methods so here I’m proposing solution for all Xperia Z DoCoMo lovers here.
This package contains three files. One for Flashtool file having system partition and wiping removed. Two for files in system partition of ROM version 10.1.D.0.343 having identical files removed. Three for optional wifi fix for people using DooMKernel as WiFi driver is different to ones in DoCoMo ROM.
Requirements:
1. Working Xperia Z having DoCoMo ROM version 10.1.D.0.333 flashed
2. Rooted
3. CWM/TWRP Recovery support
4. Latest FlashTool for Xperia Z
5. DoCoMo ROM version 10.1.D.0.333 Flashtool file in case you’re screwed up
Installations:
1. Copy xperia_z_docomo_10.1.D.0.343_update.zip to storage. If you’re using DooMKernel, copy xperia_z_docomo_doomlord_wifi_fix.zip as well
2. Shutdown and startup to Recovery menu
3. Flash copied files in 1) respectively.
4. Clear dalvik cache (not cache)
5. Turn off your phone
6. Open Flashtool and flash SO-02E_10.1.D.0.343_update.ftf file. Make sure to exclude baseband if you don’t use Japanese model and KERNEL/FOTA if you’re using DooMKernel.
7. Reboot. Now you should see phone starting up with ROM version 10.1.D.0.343 with root and recovery

Thank you so much!
Can you send me the latest version root for firmware .333 before I upgrade firmware .343?
And I don't use DooMKernel, can you send me the last compatible DooMKernel with my SO-02E firmware .333? How do I do with the new kernel?

I recommend flashing SuperSu v1.25 or newer after rooting. For kernel, just flash v06. It's from global ROM but I made wifi fix so that it can be used with DoCoMo now.

My bad. I made huge mistake forgetting to remove clearing system partition line in WiFi fix. Now it's fixed.

ZL?
does this one works on xperiaZL C6503?
i want docomo system coz im using docomo sim card. but my phone is rooted, chenged roms... lol pls help~~ ^^

My SO-02E is always stuck on the Sony logo after trying this update, I've already tried flashing the zip file with TWRP and CWM, not wiping cache and not excluding any file in Flashtool.

Hi,
I'm using the Japanese model (SO-02E from Docomo). My phone is already rooted and has TWRP recovery.
I just want to confirm that I do NOT exclude anything when using Flashtool, am I correct?

Me too, has anyone successfully got this working?
I did the following:
1. installed xperia_z_docomo_10.1.D.0.343_update.zip via TWRP
2. cleared the dalvik cache
3. flash SO-02E_10.1.D.0.343_update.ftf
All I get is a Sony logo
I have the 10.1.D.0.333.ftf and a nandroid backup so I can restore my backup

I think the xperia_z_docomo_10.1.D.0.343_update.zip is borked. I tried everything and it doesn't work

Yep, I've also tried using OTA Root Keeper but then the official update will have errors, so my SO-02E is stuck at 333.

Honestly there's really nothing from the Docomo ROM that I neither need nor use so I'll test out 10.1.1.A.1.253 explained from http://forum.xda-developers.com/showthread.php?t=2282415 sometime this weekend.
I already have my nandroid and Ti backups and the 10.1.D.0.333.ftf in case I want (or need) to revert back.

I can't really find info about it (or I completely failed to find the obvious :s)
I have a Docomo Xperia Z with (unfortunately) a locked bootloader.
It got updated to .343 by my docomo shop when I sent it in for repairs... And I lost root in the process.
Could I downgrade it back to .333 by using flashtool? So I can root it, and then upgrade it to .343 with this trick?
Or is that a bad idea with a Docomo phone? Wouldn't want to brick it.

You can easily downgrade back to .333 using flashtool, root it then do whatever.
Personally I'm using the eXistanZ V3 ROM on my docomo XZ :good:

check out my thread on how to upgrade to stock .343 w/root.
You'll have to downgrade back to .333 using flashtool, root it and install XZDualRecovery. From there just use my files and you'll be on a stock .343 w/root and XZDualRecovery. I've tested this on my SO-02E and it works. You won't lose any data and apps when upgrading.

hello fellow docomo so-02e users, for those of you that is using roms other than docomo ones, did you get your nfc to work?

is it possible to flash a custom recovery and kernel in a docomo xperia z?

official update after rooting without flashing ?

hello
is there any way for have official update after rooting without flashing the rom ?
is there anyway to unRoot Xperia SP ?
Thanks

You can unroot your phone flashing a stock ftf file via flashtool.
As about updates, many members here upload ftf files once released, so waiting for Sony to release the update on your country, from the moment you can flash the ftf file some hours after the release, is kind of useless l (just my opinion mate).

can you explain it a little bit better?
my girlfriend has the phone und i unlocked the bootloader, rooted it and installed a custom kernel (What is this? dont know the use of it) and now the phone says "cant install update" (12.0.a.1.257)
(german phone)

Custom kernel lets you get the whole control of your device. You can use it for better battery life, overclock etc. All custom kernels in order to be installed, you have to have unlocked bootloader.
But, when you unlock the bootloader you void your warranty, you loose bravia engine and you can't update using Sony pc companion.
You can still though relock your bootloader by flashing via flashtool a ftf file that you can find on development section.
If you want to relock your bootloader, I suggest you to download an ftf file of the update and flash it and after that flash the ftf file in order to relock bootloader.
Flashtool is an app for pc that lets you install ftf files.
Ftf is the extension of the update that Sony releases.

so what exactly is a (the) tft file?
and how can i upgrade the phone?
is it also possible to use new android 4.2.2 (from sdk) like google nexus?
sorry but i dont know anything about original software from sony, always had custom rom on my lg ^^

No, you can't use LG files because it's not compatible with your device mate.
Ftf files are the format of the stock file. When users download an update from pc companion, they create a file so other members can use it even if in their country the update is not released.
You can check how to use flashtool on YouTube. With flashtool you can install ftf files.

i already used flashtool but i just didnt know for what and i just used it to install the xperia Z drivers (dont know why i had to use them for my c5303, others didnt work)
i used this kernel forum.xda-developers.com/showthread.php?p=42642971 and flashed via fastboot (just oldschool and how it worked ever on my old lg ^^)
by the way: it was a .elf file, not tft i think ^^
okay i hope i got it now. it is for: - samsung devices (only) and - necessary for using the original rom?!
but the last questions:
which kernel do i have to download to update? (german)
and: do i have to save the data? (dont have CWM on this phone, but titanium Backup)
sry for the dumb questions, but this is all so complicated for this **** phone (i hate it, but lucky it is not mine)
Offtopic:
for my lg i installed fastboot, download CWMrec, downloaded a custom rom, rooted, installed everythink, all done nicely :victory:
for the nexus 7 it was even more simply. used a nexus program, type a few numbers, all done
for this phone i had to install like a bunch of programms, had big problem with drivers, read dozens of sites (the technical one are not so easy for a german guy ^^), had to register imei, unlock bootloader and so on... very much crap for a 350€ phone... with old android 4.1.2

I really don't think you should be messing with unlocking bootloaders and playing with the kernel if you don't even know what it's for.

[Q] Xperia V 9.2.A.199 Impossible to Root

Hello this is my first post , I am a newbe.....
I made several attempts to root my device but none of these works...
One click root

could you give me an help please ?

No easy method work for now. Only solution is downgrade to 4.1, root and flashing some rom based on .199 build. Or there is some script that should help you retain root with OTA upgrade, but you still need to downgrade to 4.1.

I am very grateful to you. you saved me from headache....

I would like to take advantage of your willingness to ask a few questions....
I have done a firmware backup using the SUS and Flashtool.
Bootloader is locked at this time on my V.
I would like to know if I can install cyanogenmod 11 and in the future I can back to previous original firmware "tft" using this Flashtool procedure ?
-how to install the newest Android 4.3 for Sony XPERIA V LT25
-paste the ftf file downloaded in step c) to folder „Firmware“ included in the XPERIA Flashtool.
-open the XPERIA Flashtool, click on flash and choose downloaded firmware, than click ok.
-turn off your phone and when Flashtool shows pop up window, connect phone to PC with holding volume down button
-after few minutes all is done and your phone gets the new firmware
Installing CM11 Xperia V is automatically rooted ?
Back to previous original xperia firmware, using flashtol, remains something of CyanogenMod ? Device returns unrooted ?
Thank You

First of all CM won't work with locked bootloader, and you can't install it using Flashtool. It contains Superuser app so it's rooted.
You can always flash your device with Flashtool using .ftf files to return it to stock firmware.
If you choose to unlock bootloder consider backing up TA partition of phone (there's a tool for that here but the phone has to be rooted http://forum.xda-developers.com/showthread.php?t=2292598) so you can restore your DRM keys later (if you return to stock firmware and you want to have Bravia engine and the rest of the stuff dependent on DRM).

yesterday unfortunately, I made confusion between ROOTING and UNLOOK BOOTLOOADER so I have unlocked bootloder using flashtool and the day after I have re-locked it. Have I lost sony DRM ?
I think no... becouse I don't make changes that affected device partition, is it correct ?
So I ve got to wait for better and simple method to root my device before make other experiment, what do you think about it ?

I think you lost it when you unlocked it cause TA partition got formated, it doesn't matter if you relock it afterwards.

Check if in the Album app if pictures change when using Bravia Engine; if you didn't back up your TA partition before unlocking, as far as I know, you lost your DRM keys forever, relocking won't change a thing.

CONFIRMED I lost DRM keys...
At this Point I decide to dance, I' ll downgrade to a version to root device by doomLord patch first. I found a post in which users explain how to install Bravia Engine 2 using PimpMyRom App. Finally I Will upgrade to Last Xperia firmware.... And I' ll do a big backup!!!
Are you according to me? You suggest to me something different?

I'd not worry much abt Bravia Engine. The pics appears slightly brighter, shadows are therefore a bit better, and the colours are a tiny whee little bit more vibrant. If I had to put it into a number the difference is somewhere below the 10 % mark %. You get better results by taking pictures properly in the first place.

Wrong forum bro, this is for development, not for Q&A.
Anyway, u can check ur bootloader status by type *#*#7378423#*#* in dialer (*#*#service#*#*)
Then tick service info
Then tick configuration
U will see bootloader status there
For other questions, use search function or use Q&A forum :thumbup:

You have to unlock the bootloader before you can install non-stock kernels. Search in the forum on how to unlock the bootloader. As the person above said, go to the service menu and check if it say Bootlocker unlock allowed = Yes or No. If it says No, then you are stuck and can only install stock based roms. If it says Yes, then you have to manually unlock the bootloader once using step by step guides available on xda or sony.

[Q] Question Before i do

My phone still unroot and locked Bootloader and Im made mistake upgrade to latest official stock ROM lollipop 5.1.1 bec im having overheat issues, battery draining and weird popup. then im about want to downgrade to kitkat and flash ftf firmware with root.
1) Do i have to Backup TA before i use flashtool? i think if i do flashtool, i will lose DRM keys like sony features? (for locked bootloader)
2) What meaning by 'pre-root' firmware? (*sorry about this. it look new word to me*)
3) without root phone and unlocked BL, is it possible to use PRFCreator? (link: http://forum.xda-developers.com/xperia-z1/development/c6943-368-official-lollipop-5-1-1-t3218004)
I made decide not to unlocked bootloader bec i know its risk to lose but i want to keep it simple only.

2) What meaning by 'pre-root' firmware? (*sorry about this. it look new word to me*)
3) without root phone and unlocked BL, is it possible to use PRFCreator? (link: http://forum.xda-developers.com/xperia-z1/development/c6943-368-official-lollipop-5-1-1-t3218004)
I made decide not to unlocked bootloader bec i know its risk to lose but i want to keep it simple only.

you only need to backup your ta partition if you plan to unlock your bootloader. By Unlocking your bootloader you will lose your DRM keys. Anyways having a backup of your ta portion isn't nothing bad.
Using flashtool and flashing a stock firmware will not unlock your bootloader.
2]
A stock firmware comes unrooted. Pre rooted means that the firmware comes with root integrated.
3]
PRF Creator is a Programm you use under windows
4]
You have to understand what a ftf file and a flushable zip means.
Ftf files are flashed with flashtool.
Flushable zip files need a custom recovery to flash. For example twrp or cwm or philz recovery. To get a custom recovery on your phone your phone has to be rooted.

1) If i flash custom firmware will not touch bootloader? (im planning to install custom rom from http://forum.xda-developers.com/showthread.php?t=2716182) but their instruction said "for Locked bootloader only: Backup TA Partition"? does this mean will unlock bootloader? (**im confuse**).
3) Yeah run on windows only but is it possible to use it without root phone and unlocked BL ?

1. Yes, you need to unlock the Bootloader.
2. You can use Flashtool to flash STOCK FTF on your phone.

PRF Creator is a stand alone Programm that doesn't require a phone.
It only needs files as input and the result is a flashable zip you must flash with a custom recovery

No.
This zip will launch a program called aroma installer. With this program you will be asked what you want to install.
For example the description of iHackers rom says that you have to choose between stock or custom kernel.
3]
To flash a custom rom or custom bootloader you must unlock your bootloader first. If not you can't flash anything custom.
You can unlock your bootloader with flashtool. For that you need the unlock key for your bootloader. You do this in fastboot mode with the help a flashtool.
Flashing a ftf the phone is in flashmode.
Fastboot mode and flash mode are two different states you can put your phone at.

I am not sure. As far as I understand yes if you choose locked bootloader.
Maybe some other member can help here too.
But to flash the zip you need a custom recovery. For a custom recovery you need root to install it.
Post #4 at ihackers rom Threads mentions the step to flash the rom on a phone with locked bootloader. Not that easy!

Answer is Yes. I've already tried iHackers ROM on my Z1 w/ locked bootloader. I don't want to be rude or anything but all your questions are answerable by going through some basic reading materials that are all available in XDA. I strongly recommend you do your reading first. We don't want you coming back at us saying you now have an expensive paper weight, or that you have lost some important audio, video, image, SMS, MMS, Contact, etc. on your phone. It would really help alot if you read the iHackers ROM thread as well.
You did state on your initial post that you want to keep things simple. Then I suggest rooting your phone, get rid of the apps you won't ever use and just keep it stock.

I just want to answer this and sum it all up.
Do i have to Backup TA before i use flashtool? i think if i do flashtool No, you don't need to Backup your TA partition to use Flashtool. Flashtool works for both locked & unlocked bootloaders.
i will lose DRM keys like sony features? (for locked bootloader) I'll treat this as a separate question. Yes when you unlock your bootloader you will loose your DRM keys, which is why you need to backup your TA partition first before you unlock your bootloader. But as I mentioned earlier - No, you don't need to backup your TA partition if you will not unlock your bootlader. And -No, it is not needed to be able to use flashtool.
What meaning by 'pre-root' firmware? It means it is a stock Firmware that has root access. It is basically your stock firmware that was ran through PFRCreator.
without root phone and unlocked BL, is it possible to use PRFCreator? It's basically like this... NOTE: This is a not-so-details procedure but it will give you an idea on what the PRFCreator is. So the answer is Yes, it is possible to use PRFCreator with a locked bootloader but you need to have a rooted phone with a custom recovery so you can flash the pre-rooted 5.1.1 *.zip file you made, then flash the 5.1.1 FTF using Flashtool
1. Install flashtool
2. Download a 5.1.1 FTF using XperiFirm (it's an icon in Flashtool that opens a FTF downloader that automatically unpacks and makes you a FTF that you can flash on your phone)
3. Download PFRCreator
4. Using PRFCreator you basically create your very own pre-rooted 5.1.1
5. Now you have Two(2) files - the flashable *.ZIP file (the file generated by PRFCreator) and the 5.1.1 FTF you have downloaded earlier
6. You will need to root your phone and install a custom recovery partition on your phone so you can flash the *.zip file you have created using PRFCreator, then flash the 5.1.1 FTF using flashtool
7.
