Xperia Z2 23.1.A.1.28 root - Xperia Z2 Q&A, Help & Troubleshooting

Hi
I have Sony Z2 ,D6503 ,Build Number: 23.1.A.0.690 ,Android:5.0.2 With Root
i want to upgrade to 23.1.A.1.28 with root
Thanks

Then go into the 23.1.A.1.28 Thread and follow the guide )

Exactly. If you want a fast run down (don't do this without reading in full) flash the new zip via recovery, then using flashtool flash the stock kernal without wiping any data and with a few exceptions (can't remember which off the top of my head) but it's a simple process.
If you don't want to lose recovery in the process, reflash a zip of the dual recovery right after flashing the .28 zip.

i think you should wait for someone who make Pro-root .zip,

There is one, there's a whole thread about it.
Basically the same instructions as with the 726 zip but with the 28.
Search tool is your friend.

Wake up please and check next time the general topic: http://forum.xda-developers.com/showthread.php?t=3082166

Here is a debloated (most of sony apps deleted) firmware:

You don't need flashtool for this, just put it on your SD-Card, flash it and wipe cache/dalvik

Via Wotan Server,but it will cost you 2 euros or flash this version via Flashtool. https://rapidshare.com/#!download|1...266662|R~2C3B93AFF3A3AA8419FBFA1C02642EB2|0|0
Here is how i did it for my NEO-V , please be cautious while selecting the files .
There may be other ways to downgrade, but i did it following ways.
1. Get the tft file - Choose for flashable 42
http://forum.xda-developers.com/showpost.php?p=19808360&postcount=3
Then extract the tft file into firmwares folder in the flashtool menu.

[Q] Root and Flash ROMs on 757 firmware

Ok, now i'm really confused.
I'm currently on 757 firmware and I want to flash the GPe on it. What exactly do I have to do?
LordManhattan's thread simply requires me to flash some files but the GPe thread needs me to flash boot.img or something.
Can anyone coach me step by step? I've never tried to flash a darn phone with so many prerequisites... It was so much easier playing with the LG and hTc

From stock 757 with unlocked bootloader:
Copy ROM zip to sdcard of phone
Flash boot.img from the ROM zip using flashtool and fastboot mode. the boot.img will have recovery already in it
Boot the phone into recovery, vol + or - while booting
Factory reset (or format data and wipe caches
Flash the ROM zip from recovery
Reboot into system
I assume you have followed lordmanhattan's guide and have:
Downgraded
Rooted
Backed up TA
Unlocked bootloader
Updated firmware to the latest

So it is okay to directly downgrade from 757?
And what do you mean by updated firmware to the latest?
And the boot.img in the ROM package, does it already contain the recovery?

You want to downgrade to root? if so then yes - see my downgrade sticky thread in the general section for a guide
After rooting/backing up TA/unlocking bootloader you will want to flash the latest firmware again to get the new baseband, and a few other things else any custom 4.3 or 4.4 ROM's won't boot and/or will have IMEI issues

Ok to be honest, im trying to flash that ROM because the recent 757 firmware was supposed to fix the sound bug issue. It worked for others' ZU except for mine. Pretty pissed that all SONY said to me was to bring my phone down for a repair, hence i was hoping i could fix it by flashing another ROM.
I downgraded to .532 then updated it back to 757. Seems like it is a hardware problem...
WOW. I'M AN IDIOT. I DECIDED TO WASH MY PHONE UNDER THE TAP BECAUSE IT WAS A LITTLE DIRTY. AND SOMEHOW, THAT FIXED THE SOUND BUG. SOMEONE PLEASE SLAP ME IN THE FACE.
Close this thread please, I'm an idiot. Thanks blueether for your help!
You don't read very well do you?
All the steps needed were there with an explanation of why (where needed).
Next time you you need/want to flash your ZU take the time to read the steps, and ask questions if you aren't sure about a step or why some said to do something a certain way or to see a certain thread...
ps good to see you have the sound working again

So am I right to say that the boot.img from the GPe rom in the development forum already contains the recovery?

Correct, but only the tweaked version. That's an isolated case though, so the rest of them will have recovery.

Hi...I'm in the same position as you...can you please explain how exactly you managed to fix it?
For reference, my C6802 was on stock .757 firmware, then I flashed the unofficial SlimKat rom and kernel from here - http://forum.xda-developers.com/showthread.php?t=2712065. Everything works in the rom except it doesnt connect to my mobile network.
Thanks a lot!

Not the same issue ( or at least shouldn't be).
In about phone settings do you have a valid imei no. and baseband?
Have you tried any other ROMs?

Thanks for the response blueether! In the phone settings it says Unknown for both baseband and imei. I found this thread where you helped another person with almost the same problem I guess, (http://forum.xda-developers.com/showthread.php?t=2738141) and you have told him to follow these steps:
"Just do as has been said a thousand times...
Downgrade to .532 - see my downgrade thread
Root using either [NUT]'s dual recovery or bin4ries tool - see thread in step above or LordManhattans guide
Backup the TA - see LordManhattons guide
Upgrade to latest FTF
Unlock bootloader
Root using jackies099's kernel
..."
So I'm downloading a .532 FTF and will try out these steps once the download finishes in a while. As I understand, when I upgrade to the latest FTF (.757 now?) the imei/baseband should return.

IMEI/baseband should be fine if you were on 757 and flashed slim.
You could just try reflashing any 4.4 FTF you have laying around while you wait for the other one to download

Not sure why they vanished. Unfortunately I'm sort of a noob and don't have any FTFs lying around. I read some more threads and now I'm wondering what I should try first?
A - Flash 290 FTF then downgrade to 532
or
B - Straightaway flash 532 FTF
or
C - Flash 757 FTF

"flash 290" was written a long time ago when it was the 'current' firmware. I would flash 757 first and see how that works out.

[Q] sony xperia z ultra root lollipo 5.0

Sorry if this question was asked before but i wanna know if there is a methot to root sony Xperia z ultra 5.0 lollipop,model C6833 with firmware 14.5.A.0.242. If anyone knows a good way to root it please post it here. TThanks in advace!
I'm afraid that we don't have "one click root" right now.
You would have to downgrade back to 4.4.4 (with root and custom recovery) and flash a pre-rooted 5.0
This guide worked for me.
Thanks but the thing is that i am allready in 5.0 and i don't have a rooted device....so...how can i di that downgrade in order to root it?

There is a section there when you are already on 5.0.
I too was already on 5.0 and no root but following this guide, I now have a rooted 5.0.1.
Basically, the steps are:
1) Unlock bootloader
2) Download 4.4.4 FTF and use Flash Tool to downgrade your phone
3) Root and install custom recovery on your downgraded phone (you should already be on 4.4.4 by this time)
4) Download 5.0.1 FTF and create a pre-rooted flashable 5.0 using prefCreator
5) Flash your pre-rooted 5.0
Read the guide, you can never get lost.
Thanks a lot!!

hello all.
all the info out there is really confuse me.
some one please give me a valid links to here.
please correct me if im wrong somewhere in my understanding:
i own xperia Z2. my version is 5.1.1 stock.
the sound is crazy low ( after i put the max db at setting-sound...), so i searched what can i do about it, i've found there is a mod that fix this. as i understand, for that mod i should have recovery and rooted device, so i thought to myself "hey, if im gonna do root and install a recovery ill also will flash a nice rom"...
so i tried to follow some guides here but they are realy confused me.
at the links it says the root won't work for any device...
also it says it is gonna work for lockboot or something...
more over there is many methods and i dont know what is the simplest one.
there is more info that realy confused me and i want to be 100% sure im doing the correct steps...
I know i need to root and install a recovery, then i i need to pick some rom and flash it ( right?)
so please give me a links to here for what i need to flash a rom for my sony xperia z2 device ( v 5.1.1 stock).
ty for helping.
1.
The way i'd root my device on a locked bootloader is
- download flashtool and a older Firmware FTF
- FLASH the older firmware to my device and on the older firmware use a root tool to root my device
- I can now use root access to install recovery (XZdualrecovery)
- Download PRFcreator and a newer FTF with a superSU flashable zip
- Use prfcreator to make a flashable zip out of the new FW( include kernel and and all )
- copy it to device and flash it and be sure to wipe caches and data per big flash (e.g heavy FW changes)
- also google around for some things and make sure it all matches your device
(FTFs and xz recovery)
Also search for TA backup it may be useful for before you unlock your bootloader if you do
2/1. Use xda search tools to search Z2 section for root tool scripts
2. FTFs can be found in general section
3. You may want to add xz recovery to your upgrade flashable zip
4. Feel free to ask any aditional questions if you need more direction or detail
5. Unlocking your bootloader voids your warrenty (and wipes TA) if you restore your TA sony cant tell if you have unlocked your bootloader or not
(it also relocks your BL upon restoreing so be on a stock kernel)
what is FTF? is it the android version i have?
why i need an older one? i cant flash with 5.1.1?

FTF
I dont know its definition but its a full Firmware with included partitions so its essentially a factory firmware package
Kindof
Ita FW version and android verson
- Android rootkits use security exploits which google or sony may patch respectively
Rootkits dont work with newer FWs you will have to try 4.4.2 or the 55FWs
That guide looks good
After flashing if be sure to download a Newer FTF that matches your ROM version and be sure you flash only kernel
(exclude all) (some roms may not include a kernel)
To flash a rom after that one you can reboot into recovery and flash any stock based rom (and stock kernel to match Fw Version if it changes heavily)
Rootkits dont work with newer FWs you will have to try 4.4.2 or the 55FWs

what do u mean by that? i wont be able to use v5+ roms?

55fws i ment the last numbers of a build number
The bugs that rootkits exploit are mostly fixed on newer Firmware versions (fw for short)
You need to downgrade to 55 or 402 fw to use some of the rootkits
i following those steps:
Flash official Sony's 4.4.2 17.1.2.A.0.314 with flashtool (http://forum.xda-developers.com/show....php?t=2162907)
Root using any method
Install NUT dual recovery (http://forum.xda-developers.com/show....php?t=2261606) or the recovery of your choice.
Reboot in recovery, Wipe Data, Cache and Dalvik Cache.
Flash the rom.
Follow AROMA Installer.
so i went to do step 1:
but there- it is written:
With this release, before unlocking first time, root your device
so? i need to do step2 first, then step1?
That comment is about unlocking you bootloader. So no step 1 then step 2.

Help upgrading my rooted 4.4.4 D6503 to latest version

Hi,
I have a Sony Xperia Z2 D6503 with Android 4.4.4 KK already rooted.
Now I would like to upgrade my Android to the latest available stock Rom without losing root, DualRecovery or my data, in order to be able to use Magisk.
Could you tell me the best way to do that?? I assume I have to create a pre-rooted Firmware and upgrade through DualRecovery. How would I do that??
Thanks so much for your help in adavnce!
You can download the firmware you want from this topic : http://forum.xda-developers.com/xpe...-z2-d6503-customised-tur-23-5-t3442058/page10

There is no need to flash anything else just download the the customization you want(like Mena Arabic for persian language)and there is almost zero different between them
And flash it through recovery and there is no need for fix many times but if you got stuck in bootloop just flash the bootloop fix : https://mega.nz/#!AJcwERiQ!FUmk6eS5aoVsFSZ1f4WZIELIt7sckPCj11n0AIdCNzU
Okay thanks so much, this is what I thought. Download the zip, install via Recovery and thats it. Perfect
How did you root kitkat 4.4.4? Do you have pre root firmware for 4.4.4?
