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?
Hi everybody!
This is my first post as I usual solve my problems just by reading others people posts.
I recently flashed my z1 (C6903) to 14.2.A.0.290 Generic NCB (Unbranded/Nordic) (4.3 android) as I didn 't like the DE(german version) with the bloatware. I rooted it before with kingo but lost my root after flashing the NCB version I'm now looking for a way to downgrade to a older ncb version root it with kingo and then do a ota upgrade to keep the root. Does anybody have the FTF therfore and what boxes should I pick I want to keep my data or should I let it do a full wipe do a backup with sony companion or the sony app on the phone and than play it in after finishing the downgrade root and OTA? Pls help me I' m completly lost and I'm really missing the root.
Thanks in advance to everyone!!!!!

My experience is that if older FTFs aren't in the mega thead (http://forum.xda-developers.com/showthread.php?t=2469191), then you won't find them anywhere. Mega thread only has a 290 FTF for NCB, so you may be SOL if you want to strictly downgrade to 534 NCB and then OTA to 290. However, as long as you flash a generic FTF, you won't get carrier bloatware.
If root is what you'd want, I'd go with [NUT]'s pre-rooted 290: http://forum.xda-developers.com/showthread.php?t=2572988. It's the easiest way to get full root.
..or you follow the instruction step by step here on page 2, post #16 http://forum.xda-developers.com/showthread.php?t=2588331&page=2

Here's a link to the correct FTF (note that it is .257, so follow the guides regarding rooting .257, or if you're savvy, install a .534 kernel, root with Kingo, install a .257 kernel again, then OTA)
https://mega.co.nz/#!WkolCYjB!IIXR5SgAn-J05MXmG26GYyi2P2sYcF34Avn73z5Y9n0
It is incorrectly named Generic SE, but it is the right customisation ID for Generic NCB (1276-9897).

Sony PC Companion can make a backup for you, I don't know how much will be saved as in order to flash a 4.2.2 ROM you'll need to wipe your data partition.

257 can't be rooted manually, only 534 can be rooted by vRoot/Kingo/etc.
Since you are downgrading, you must wipe data and will lose everything you don't copy off the phone.

No, it's not possible to upgrade 257/290 and keep root. You asked about downgrading, not rooting 290. If you have an unlocked BL, go read the dev thread on how to root 290. With a locked BL, you'll need to get rooted 534/257 and then flash a custom pre-rooted ROM from the dev forum.

Actually with OTA you keep semi-root, but in essence you're right. Actually I think the easiest solution is to flash a stock .534 ROM, root it with Kingo, grab TA partition backup, flash .290, unlock bootloader, flash a recovery, do a proper root, reflash stock boot partition, flash TA backup.

Yeah, true, I've just stopped telling people about partial root since full root is possible. Those who don't know to ask don't know what it means anyway, and it's just simpler for everyone involved to leave it out.

Hi,
I'm trying to backup the TA on my Xperia Z1 (C6903) running the stock KitKat firmware (14.3.A.0.681). From what I understand though, you need root to backup the partition, but to get root, you need an unlocked boot loader. I've seen a few tools that roots without unlocking the boot loader, but I need to downgrade the firmware to at least Android 4.2.2. Downgrading requires an unlocked boot loader.
Are developers working on a root-and-unlock tool for 14.3.A.0.681? Is there already a tool out there?
Thanks in advanced. Sorry for my arrogance.

You do not need an unlocked bootloader to get root and or to downgrade. Although yes, you would have to downgrade to 4.2 to get root. Just use flashtool to downgrade and pick a software to root

I've used vroot 1.7.3 english and everything installed fine. However, when I installed the Root Checker app from Google play it reads "Sorry, this device isn't properly rooted."
Here's what I did / planning, in order:
1) Downloaded C6903 14.3.A.0.681 Global 1277-2880_R5C
2) Downloaded 14.1.G.1.534 downgrade FTF [NUT]
3)Pasted the 2 FTFs in the Firmware Folder under Flashtool
4)Flashed 14.1.G.1.534 downgrade FTF [NUT] using Flashtool from Androxyde (latest version)
5)Installed vroot English (1.7.3)
6)Clicked on the Root button. Phones reboots twice
7)After phone first start I was greeted with an error message from "Kingsapp".
8)Installed Root Checker from Google Play
9a)"Not properly rooted" <-- I'm right here
9b)If "root successful", proceed to flash C6903 14.3.A.0.681 Global 1277-2880_R5C
I did some research and people are pointing everywhere, vroot, bin4ry's rooting method, 360 (can't install).
Did I lose my TA partition? My X-Reality goodies?
What am I doing wrong?

Okay so now you are still on .534 firmware right? Do you have usb debugging on?
And also try rooting with bin4ry if vroot doesn't work for you.
Don't worry, you won't lose x-reality unless you've unlocked your bootloader

I have just purchased xperia z1 and has updated it to latest .757 and wants to root my mobile. May be this type of questions are already posted but i find some questions in my mind before rooting so I want too clear it out so that i may not be left with a bricked device
1. can the c6903 firmware be flashed on my c6902 without any problem ( such flash was not applicable on my galaxy ace and there was no any correct way, you are left with a bricked device, but I see only c6903 threads)
2. if so , can i flash the link of ftf on NUT thread (it is c6903 ftf----- else i have to go to ftf mega collection and flash c6902 IN ftf?
3. can the flash tool unlock and lock bootloader so that i get my warranty again ( will i loose root after locking bootloader ?)
4. does unlocking bootloader crashes camera? ( i think i read months before that 20,7 mp stop working)
5. if unlocking bootloader crashes camera shall i install Z1-lockeddualrecovery2.7.123-BETA.flashable.zip (8.47MB) from this site http://nut.xperia-files.com/ from flashtool ... if so plz tell how ..
6. how can i relock bootloader, if i unlock it?
7. what flashiing ftf withou ta means?
8. does flashing kernel, recovery and ftf are same ways i.e just put them in flashtool/firmware path and use "flash" button and follow flashing..(please do elaborate here, if u can add pics thanks). I read the noobs guide but it was for xperia x10.
9. After rooting-- flashing recovery-- all i have to do is wipe data, dalvik cache and install rom
10. i also got my back glass cracked due to my phone getting placed under my bed table while studying... i read many T&C of accidental warranty policy,, so is this reason a valid reason to get warranty,, how much will be the cost of changing back glass as accidental warranty is only 1 time useable..
At last thanks for giving your precious time and clearing my doubts

Hey guys! Just bought brand new Xperia Z1 10 days ago! I LOVE my new phone but I really need to root it to have access to my game files and bypass the restriction on apps on SD card. Still a noob about rooting so I've read several guides in here, all are very useful and answered many of my questions/confusions.
Btw, my Z1 is C903 model, running 4.4.2 KitKat, on firmware 14.3.A.0.757. I've checked and it's not rooted (obviously) and its bootloader is locked but unlocking is allowed. Now the questions:
1. I just want to root my Z1 for now. Is it possible to root it WITHOUT downgrading my firmware OR unlocking the bootloader? That is I don't want to downgrade nor unlock the bootloader, IF possible.
2. If the above is not possible and I need to downgrade it first no matter what, is it totally safe to root it without risk of bricking it and no further issue will arise (camera not working, etc)? Just assume everything is done correctly using krabappel2548's guide. Would be nice if anyone with same phone spec can confirm on this.
The idea is to root my Z1 first so that I can backup my TA partition. After that, I won't mind unlocking the bootloader and willing to try some custom ROMs later. Thanks in advance for any help regarding this!

1. I just want to root my Z1 for now. Is it possible to root it WITHOUT downgrading my firmware OR unlocking the bootloader? That is I don't want to downgrade nor unlock the bootloader, IF possible.

No.

2. If the above is not possible and I need to downgrade it first no matter what, is it totally safe to root it without risk of bricking it and no further issue will arise (camera not working, etc)? Just assume everything is done correctly using krabappel2548's guide. Would be nice if anyone with same phone spec can confirm on this.
The idea is to root my Z1 first so that I can backup my TA partition. After that, I won't mind unlocking the bootloader and willing to try some custom ROMs later. Thanks in advance for any help regarding this!

Use latest Flashtool and Downgrade to .534, provided by NUT, Install DualRecovery, Upgrade to pre-Rooted .757. Done.
Easy and safe, just follow the instructions. Now you can Backup TA and Unlock Your Bootloader.

Got it. Thanks for the fast replies guys! Seem those are the best way to proceed. And thanks for the heads up about VRoot! :good:
Will try to root my Z1 tomorrow. I'll update on the result.
Hey guys! I'm ready to do this. Just done downloading all the required files today. Made backups of my data, saved in SD card. Installed flashtool 0.9.16.0 and its drivers. Device connected and recognized.
Now to flash the .534 firmware. Just done downloading it from here but just noticed that the file is of *.zip extension instead of FTF (prolly because I used direct download instead of torrent).
So how do I proceed with this? Flash it like flashing FTF file as well?

Try to download from different source. It have be FTF extension. ZIP extension can be changed to FTF but many reported it will not work doing that. Try and let us know.
I did it guys! :victory: Successfully downgraded to 14.1.G.1.534 [NUT], installed XZDualRecovery v2.7.123 BETA and then upgraded to pre-rooted 14.3.A.0.757 [NUT]! Stuck a bit at the middle but I did it! Now I have root access and my Z1 bootloader is still intact! It took me ~2 hours to complete everything last night.. :laugh:
I'll post a detailed logs of what I did later, just for future reference and for others with same phone spec. And thanks again gregbradley and eclyptos for the help!
As promised, the detailed logs. Just for reference for others like me that are still noob about all this.
My phone spec: Xperia Z1 C6903, running 4.4.2 KitKat, on firmware 14.3.A.0.757 (no root, locked bootloader).
Guides used:
-Root, Backup TA, Unlock bootloader and more! The ultimate Xperia Z1 guide
-[25NOV][FLASHTOOL GUIDE] HOW TO for n00bies - G-FACE GUIDE
-[STOCK][C69XX][4.4] Update to 14.3.A.0.757 [Root & XZDR][DE-/ODEX]
-[DEVDB][TWRP][PhilZ Touch][CWM] XZDualRecovery 2.7.1XX RC
Preparation:
-Installed adb and USB driver (from Android SDK), Flashtool 0.9.16.0
-Phone charged to 90%+, enabled USB debugging, stay awake while charging
-Downloaded all required files (C6903_14.1.G.1.534_NUT.zip, C6903_14.3.A.0.757.flashable.zip, C6903_14.3.A.0.757_Stripped.zip, Z1-lockeddualrecovery2.7.123-BETA.installer.zip)
-Made backup for all my data including apps using Backup & Restore, saved into SD card
And here's the step-by-step of what I did:
1. Preparing 14.1.G.1.534 firmware
-copied C6903_14.1.G.1.534_NUT.zip into "C:\Flashtool\firmwares\"
-changed the extension from *.zip to *.ftf (C6903_14.1.G.1.534_NUT.zip --> C6903_14.1.G.1.534_NUT.ftf) for it to be recognized by Flashtool
-already flashed this firmware when I read eclyptos' suggestion to change the extension, so I hereby confirm that it's working!
***NOTE: Downgrading to .534 wiped out my data on internal storage (not SD card content though). Didn't know that, thought only unlocking bootloader does - good thing I've made backup of all my data beforehand.***
2. Flashing C6903_14.1.G.1.534_NUT.ftf using Flashtool
-just followed instructions on Flashtool, turned off my phone, unplugged from USB, then connected again in flashmode (using instruction in guide)
-flashing started automatically once it's connected in flashmode
-flashing done, phone turned off automatically, unplugged from USB, turned it on
-phone now on JB 4.2.2 with .543 firmware but no root access (verified with Root Checker)
3. Installing XZDualRecovery and root access
-extracted Z1-lockeddualrecovery2.7.123-BETA.installer.zip, ran install.bat, chose option 3 (installation on unrooted ROM)
-once done, phone rebooted automatically into default recovery (PhilZ Touch), chose "Reboot Now" with 2nd option to install root access (SuperSU)
-rebooted, phone now has root access (verified with Root Checker), with BusyBox v1.20.2-jb "static (2012-11-25 17:47 +0100) multi-call binary" (wasn't sure if required to have root before upgrading but tried it anyway)
4. Preparing to upgrade to 14.3.A.0.757
-copied C6903_14.3.A.0.757.flashable.zip into SD card, C6903_14.3.A.0.757_Stripped.zip into "C:\Flashtool\firmwares\"
-changed primary recovery to TWRP using NDR Utils app (pre-installed in .543), tried to reboot into recovery but reboot not working (nothing happens)
-rebooted into recovery again using adb command line ("adb reboot recovery") - Google FTW!
-rebooted into TWRP recovery
5. Flashing C6903_14.3.A.0.757.flashable.zip using TWRP
-on TWRP, chose Install, navigate and chose the file
-tried with zip file signature verification, failed
-tried again, without signature verification (MD5 check), successful
-firmware update started, took a while and done successfully!
-DID NOT REBOOT (as per instruction in guide), back to Home->Reboot->Power off, unplugged phone from USB, turned on phone
6. Flashing C6903_14.3.A.0.757_Stripped.ftf using Flashtool
-connected to USB, renamed C6903_14.3.A.0.757_Stripped.zip to C6903_14.3.A.0.757_Stripped.ftf, started Flashtool
-flashed everything in the FTF just like in step 2, phone turned off automatically once done, unplugged from USB
7. Verifying upgrade
-Phone turned on, Android is upgrading, optimized apps, etc
-Phone now back to 14.3.A.0.757 firmware but has ROOT access using SuperSU (verified with Root Checker), with bootloader still locked!
Will backup my TA partition later, but I'll just leave the bootloader locked for now. Restored my backup, checked and re-configured certain apps settings, no weird behavior so far, camera and wireless also working fine!
That's about it. Hope this log will help others to have root on their Z1 of same spec. Good luck!
I was a bit confused with the firmware you flashed, since it said it required 0.681. But like i read it now, you can just flash the .757 over the .534 right? Good info, thanks!

Yup
From 534 you can flash 757 firmware from recovery and use flashtool to flash 757stripped tft (kernel).
