[Q] Downgrade from 4.4.2 KK - 4.3 JB. Help. - Xperia Z1 Q&A, Help & Troubleshooting

First of all, I've tried searching and reading tons of forums/guides the past hours, but I can't get this to work. So please excuse me if I've missed something
I'm trying to downgrade my Xperia Z1 from (the horrible) KK update 4.4.2. to my stock 4.3 JB. I've tried flashing the following FTF's:
C6903_14.2.A.1.136_Generic Nordic NCB_1276-9897.ftf
C6903_14.2.A.0.290_Customized NCB 1276-9897 (Nordic Combined).ftf
C6903_14.1.G.1.534_1276-4314_R2A.ftf
All found here!
No one works. I keep getting bootloops (I can se the startup animation, then it restarts). I manged to get my phone working with using the orginal KK FTF (C6903_14.3.A.0.681_Generic NCB 1276-9897 (Nordic).ftf).
Could somebody please help me and figure out what the problem is? I've added my Software Info as an attachment.
Thanks for any replies!

Really weird, if you flashed them correctly from Flashtool v0.9.15 they should work, check the version of your Flashtool if is correct. Also try the one (FW .534) provided by NUT for C6903, here.

I used Flashtool Version 0.9.15.0. and yes, I believe so.
Flashmode->Choose FTF->Wipe Appslog and Cache, uncheck Data->Flash
That looks like 4.2. FW, and a custom ROM? I would like to have the original 4.3 .

Yes, but if that will work then you will have more chance to Update via Flashtool to .136 FW 4.3 and maybe get Root too (Optional).

BTW, if you still have problems then you have to wipe Data too, it may be the issue.

Hm.. I'm not sure about a custom ROM, It's a road I'm not quite familiar with, if you understand .
There isn't any troubleshooting I could do that you can think of? Have i selected the right FTF for my phone? Is it actually possible to downgrade from 4.4.2. to 4.3?
EDIT:
If I'm going to delete my data, exactly WHAT am I losing? I want to know what I have to take backup of before trying that out.

It's not Custom, it's Stock, they are all Stock, but you can have Root on it.

Yes, it is possible, I did many times. Check everything you downloaded or did, nobody can know that better than you-self.

OK, then, wipe everything and make a fresh installation of 4.3, I think this will work. Backup anything what is important to you, Pictures, Vids, or Data games to not going to download them again. I don't know, wipe everything..

You will find all on XDA just by searching the right Words.
You have to use "Flashtool v0.9.16", download the FTF from "Mega Collection" for your Model (C6902/3/6). Download the FTF "Generic" or "Commercial", the customization have nothing to do with that, put that FTF in the Folder of Flashtool, Run Flashtool, Flash, select the right FTF, put your Phone in "Flashmode" and when Flashtool asking connect the phone via USB to PC, Wipe everything Data, Cashe, Appslog. Done.
Do not ask for step by step, all what you have to know I already wrote.
Clik Thanx.

Xperia Z will not update, what steps can I take to get the proper firmware on it?

Hi folks, I have an Xperia Z and its still stuck at 4.1.2
It's a prototype model, I've used the phone now for months and its been working great despite the lack of updates but I'm hoping it can have the latest software like the rest of the phones out there.
The bottom of the phone has C6606 written on it but the image on the screen shows C6616. Any suggestions would be appreciated.

OK, that is really very strange. You could try to contact DoomLord or Apollo89, they have knowledge of such things.
Are you rooted? Can you do a CWM Backup? I suggest having a full backup before flashing another rom. So in case you need it, you can flash it back.
I am not sure if you have the same kernel as the rest of us. If you can not do a CWM backup, and are not rooted, you need to find a way to extract the file "boot.img" from the phone. This is the kernel, which you can easily flash back. But for this operation, a bootloader unlock will most probably be necessary.
If you can get no help from Doom or Apollo and can not extract boot.img, you might need to flash hoping for luck, or stay on the firmware you have.
Disclaimer: I might be much too paranoid, after all your phone seems to have the same hardware as the normal one, and a flash of a 10.4.B.0.569 ROM should be no problem. I just don't want to be the one that did not warn you and be responsable for a broken phone...
===============================================================
EDIT: Just had a look at the thread, C6616 is bell Canada, if you had found that, you could have reported back and told us that you solved the problem.
===============================================================
thanks for the advice. I still haven't tried anything with the phone. I've unlocked and flashed the firmware on my old Galaxy Nexus which for some reason also never updated (bought directly from Bell) but this one trying to read through all the information I'm having some trouble deciding on which method to use and where to really start.
If someone has a simple tutorial on flashing these phones please do share, otherwise I might just leave it as is and by the latest Nexus when this phone's done.

sorry to sound dumb, but I can't figure out which firmware to select for my phone. Can someone please recommend a link for the correct file to flash this with? Also does it matter which generic firmware I use? I don't want to get the Bell firmware and end up with all the bloatware they have on there. I'd prefer as close to a clean firmware as possible so I can start getting the latest updates onto this phone.

I think all Generic firmwares have the same "bloatware" app in common and all carrier branded firmwares have their carrier specific apps, so just choose a generic firmware and then remove all unuseful bloatware apps (if you go root).

Any info about that error??
Why not flash to 4.3 directly with flashtool or to 4.2 and then upgrade to 4.3?
Also try a fresh install by wiping data (if you have already a backup of them of course) it maybe helps..

I've tried a couple times now to update that system update, its 10.4.B.0.569, once it starts to install it goes to the robot install logo at the startup for a second then starts the phone right away without doing the full install. The message on screen is simply "could not install".
i'll try a factory reset then directly to 4.3. I'm assuming I can use the same method as before or do I need to look into rooting the phone now?

As soon you are installing a stock rom, you don't have to worry about root.
But if you wanna root, your only choice is to flash a 4.2 rom, root it with a method of your choice and then upgrade to a prerooted 4.3.
Can someone please point me in the right direction to a FW that works with my phone? the only one that I seem to be able to use with flashtool is this one here which is 4.1.2. http://forum.xda-developers.com/showthread.php?t=2390178
however it won't let me update the system!
I'm guessing that I need a C6616 firmware to make this work, but I also tried this one, http://forum.xda-developers.com/showthread.php?t=2612159 and I get an error in flashtools, in red writing 'ERROR - error flashing. Aborted'.
I've been searching on here and all the other firmwares are 6603 which I tried a couple and again errors in flashtools.
trying again with that 4.1.2 its flashing it but its not the firmware I need!
ok, finally got one of them to work! I'm not sure what it was but I downloaded a bunch of firmwares until one of them finally updated me to 4.3.
thanks for all the help!

Read forum rules, it clearly says "DO NOT POST QUESTIONS IN THE GENERAL SECTION"!
To your problem: are you running 4.2.2 or 4.3 now? In your post you say you flashed 4.2, but then you say you're running 4.3
Try to reflash a stock 4.3 ftf. This should solve your problem

I DON'T WANT STOCK 4.3 FTF
It's bad for me the both versions are bad i want 4.2.2 the best
Do you want a custom Rom or stock 4.2? Because if you want a custom Rom you should flash 4.4....
If you want to stay with 4.2.2 reflash a stock ftf
If you downgrade, you need to wipe everything, or you may get a bootloop or errors like the ones that you're seeing.

I googled but i didnt found clear one and i cant try every4.2.2 ftf because my internet speed slow 80kb\s

You can find a stock 4.2.2 .ftf file over the net or even here on xda and use the flashtool. When selecting the firmware to flash, also check the "reset customisations" option (down right) and then follow the common flashing sequence. This might fix your problem. Otherwise, use other version or pc companion or update service.

As soon as you have a backup of the stock firmware (which is an .ftf file in your case), you can experiment with your phone as much as you want. That's what I do anyways....

[Q] Rooting from Android 4.3

Hi,
I, after the long wait, foolishly updated my Xperia T to Android 4.3 (build 9.2.A.0.295). Before doing so I made a nandroid backup of my 4.1.2 install (can't remember what build). Only now do I realize this mistake as the current method for rooting requires you to start from a rooted Android 4.1.2 base. So this leaves me in a situation with a lot of questions that need answers.
Firstly, is there a back up technique that I can use (instead of nandroid) that doesn't require a rooted 4.3 device? And if so to what level does it backup (i.e what will I lose)? Or can I create a nandroid without a root? I would like to be able to use it as a safety net so that I don't lose everything if I screw something up.
If there is such a method I would like to root my device but I have been unable to find any instructions rooting from 4.3 for newbies like me. The current post by DaRk-LOrD just says "Install 4.1.2". How do I do that? Is it possible I can just skip downgrading and somehow go straight to installing CWM on 4.3 (I might be talking garbage, I don't know...)?
Also if I am to root I would like a way to get as close as possible to my current installation of Android 4.3 as possible (apps, app data, settings, etc.). How would I go about doing this? Maybe I install Android 4.1.2 from my nandroid I made before updating?
Also, does anyone know if it is likely we will be seeing a tool such as this one for Xperia T 4.3? Maybe if such a tool is in the works I should hold off for a bit longer.
I know these are a lot of question but I have been unable to find this information which is either relevant or applicable to my situation or what I find is just too complicated (steps are too broad and assume too much prior knowledge). If I have left out any information you need please don't hesitate to ask.
Thanks,

I have a short answer for you: 4.3 is not ready for prime time.
I recommend downgrading to 4.12, root it, install CWM, then flash another ROM of your choice. Look for downgrade to 4.12 threads, such as this:
http://forum.xda-developers.com/showthread.php?t=2655182
Is your bootloader locked, or unlocked? If it is unlocked simply flash a custom kernel. Then flash the supersu zip file you can find in this forum. Next step is to flash the kernel from the ftf file, make sure to exclude everything else.

I do have an unlocked bootloader.
Does the steps you have outlined above root 4.3 with out a downgrade? Will this process wipe my phone (if so how can I get it back afterwards)? Also, where can I find "a custom kernel" (which one?), "supersu zip" (like the one from Dark Lords post? What version of supersu?) and "the ftf file" (the Xperia T, Android 4.3, build 295 ftf file?) ??? Sorry but I am too new to this to understand exactly what you are saying from what you gave me but it does sound like what I want .

1. You will not have to downgrade
2. It will not wipe your phone
3. Download for example CM or Omni rom, extract the kernel and flash it via flashtool
4. http://download.chainfire.eu/382/SuperSU/UPDATE-SuperSU-v1.93.zip
5. Yes, the Xperia T .295 ftf file, if you were using it before

Is there a way of doing this without CyanogenMod or OmniROM? I would really prefer to just stick with Sony's 4.3 just rooted.
You need a custom kernel with a recovery. If you already have a custom recovery installed you can skip this step

"custom recovery"??? Sorry....
Can this be achieved from a what is basically a stock install of 4.3 with a load of apps on it?
You said that you did a nandroid backup. I'm pretty sure you did this in a recovery. There has been a guide of how to root stock 4.3 with unlocked bootloader. Search for it here and you will find it. If you have any further questions feel free to ask.

It was a nandroid of 4.1.2 from an app. Can I make a nandroid of my 4.3 install without a root (that would be awesome)?
I will search for that post.
No you can't
This post is for TX (i would assume it is adaptable by downloading the T versions of the files) but it does say wipe personal data in the instructions which isn't really ideal.
There's Dark Lords post which I found originally which goes through the steps of having 4.1.2 installed and it it also says "do a factory reset" which isn't ideal either.
There is this post which looks quite promising but is about the Xperia V (could that be adapted?)
And that is the first three pages of searching "xperia t 4.3 root unlocked"

There's Dark Lords post which I found originally which goes through the steps of having 4.1.2 installed and it it also says "do a factory reset" which isn't ideal either.
There is this post which looks quite promising but is about the Xperia V (could that be adapted?)
And that is the first three pages of searching "xperia t 4.3 root unlocked"

Thanks.

This is quite strange
1) Locked or unlocked bootloader?
2) Have you ever flashed a custom kernel?
3) Have you ever flashed a custom rom?
4) What's your original firmware customization number? EDIT: I've just seen that's 1266-6442... is this your ORIGINAL firmware? Where do you live? In Germany?
5) Rooted? CWM?

I can have locked or unlocked, thats not the problem.
Custom kernel, roms, rooting CWM and so on, i never did that, just flashing with flashtool :S
and yeah 1266-6442 is the original customization number, and i live in belgium, but 20 minutes away from Germany.

Ok, yes, I know how it works...
I just asked about the bootloader status, because sometimes some people mess with bootloader, kernel, flash from recovery, flash with Flashtool... and so on... WITHOUT the understanding of what they're doing... and come here complaining... do you know what I mean?
OK, now, I know how to help you.
1)
There's a method to download and install the original firmware directly from Sony.
But you need to be rooted. So, are you rooted?
2)
Your customization number is wrong.
1266-6442 doesn't exist.
That's maybe the number of your model, but it's not related with the firmware.
The right number for Telekom Germany is 1265-9144
The customization number is inside your software and can be found pressing *#*#7378423#*#*, inside Service info --> Sofware info --> Customization Version.
Give me that number please, so I can understand what's the software working now on you device.
3)
You said "I didnt backup before flashing, and now have false firmware, no sim signal, no wifi, battery heats as hell, and so on and so on.."
Ok, please, explain better what you did.
Have you flashed what kind of rom? Via recovery?

And i currently have 1265-1620_R1J, flashed it yesterday just so, its CE Region i thing, 4.3 version, build .295.
3)Yeah, i first had the original Firmware on my phone, had the 4.2.2 version, and then the official software came for my phone and the T-Mobile provider i think.
And then, the 4.3 is just S**t, as i sad it, just problems, and i just want the previous version, because it worked perfect.
so i just was flashing all the other firmwares, especially the 4.3, from all the other regions, i thought maybe they will work better, but nope.
And when i try to flash previous versions/firmware, it just comes to the animation, after the sony and xperia logo, and restarts over and over again :/
And no, no roms, or recovery, i didnt do anything of all that, just flashing firmware with flashtool.

Ok, now I've understood what's your situation.
It seems that when you flashed 4.1.2 firmwares, the process was not compete for some reason.
The list from which you get that number, is about all kind of xperia T... and is different from the firmware list.
The problem is that you lost your previous original number, maybe it was 1265-9144... and you can resume it only with root and a little bit of experience... and actually I'm not sure you would be able to handle this kind of hacking stuff.
Anyway I'm quite sure that 4.1.2 from CE is perfect for your needs.
Try this one with Flashtool: http://forum.xda-developers.com/showpost.php?p=42393403&postcount=29
This firmware is perfect for any european country: I tested many times and is one of the best.
But before flashing, recharge your battery to the maximum. And be sure that the flashing process is complete and without errors.
Just try and let me know...

This kind of issue is called "bootloop".
When it happens, try to push "power button" + "volume up" together.
The phone will turn off.
Turn on again and if there's bootloop again, repeat the procedure on and on and on.
Try many times...

I can't answer to the first question.
You are the first with this weird problem and I'm beginning to think that something is broken inside your phone.
Bootloops are usual when something is wrong with kernel or system, but if you say that flashing went good and this appears only with 4.1.2 , I really don't know why.
You are not rooted because you've never done before and anyway every time you format the system (flashing with Flashtool or via recovery) you lose root.
So you are not rooted for sure.
The problem now is becoming bigger, because there's no way to root a 4.3 firmware directly.
But... guess what? You have to root 4.1.2 before and then install a 4.3 already rooted. :crying:
The only way for you to root 4.3 directly is to unlock your bootloader, but this means that you lose warranty and DRM keys (that are needed to let work some functions like Bravia Engine).
Actually you could save your warranty and DRM keys with a special backup (called TA backup), but.... guess what? You need to be rooted!!!! :crying:
The second way is to try to install 4.0.4 ice cream and root it. It could work.
I give you this link https://docs.google.com/file/d/0B55PDGQqCzReV2dFSjFSNnlLLVk/preview?pli=1
It's 4.0.4 italian version...
Try this... and if it doesn't work, the only way is to unlock your bootloader losing warranty and drm keys, sorry...

LOL :cyclops: as you wish...
1) Flash 4.3 with Flashtool
2) Unlock your bootloader on Sony official site following all the instructions: http://unlockbootloader.sonymobile.com/instructions
3) Once it's unlocked, open Flashtool and re-flash 4.1.2 CE that I gave you and you tried before: http://forum.xda-developers.com/showpost.php?p=42393403&postcount=29
4) Don't turn on. Download Doomkernel here: http://d-h.st/4kK
Unpack the .elf file inside the zip
5) Open Flashtool. Connect the phone to PC keeping pushed the volume-up button. Now the phone is in fastboot mode. Click on the lightning symbol, select fastbootmode, select kernel to flash, select the .elf file extracted before, done.
6) Unplug the phone. Turn on and you will see the doomkernel logo... and now I hope that you finally enter into 4.1.2 firmware without bootloop.
7) To root: you need to copy this file http://download.chainfire.eu/396/SuperSU/UPDATE-SuperSU-v1.94.zip to the internal memory.
Turn off. Turn on pushing volume-down repeatedly, now you enter into recovery, now install the supersu zip and reboot.

DAAAAAMN ! -.- :/ DommKernel logo is there, xperia logo, animation, and blocks again, restarts all the time.. I'm really desperate...
Now you have 4.1.2 with the doomkernel and the root, which is the perfect combination to do anything on your device.
If it's working, you can leave the phone in this situation.
Instead if you really want to go back to the original firmware, go here: http://forum.xda-developers.com/showthread.php?t=2334653

Reflash 4.3 with Flashtool.
Download this Doomkernel: http://doomlord.xperia-files.com/download.php?dlid=VC1Eb29NS2VybmVsLXYwOQ==
Be aware: don't use the old doomkernel, but this one (v.09) that is specific for 4.3
Flash the elf file, as you did before.
Now you have doomkernel logo and you can enter into 4.3.
Now root it as I suggested in the previous posts (turn off, turn on pushing vol-down, flash suspersu zip, reboot).
Try.

C6903 - Baseband Unknown Fix

Hi Experts,
I have searched the forum and after flashing for three sleepless nights, I am still struck with the unknown baseband issue.
The details are:
C6903
BL Unlocked & now its locked using Flashtool (DRM or TA backup is unavailable )
Currently the phone is struck in boot loop in .534
Used Flashtool ver. 0.9.22.3 & 0.9.18.6
Latest EMMA & Xperia Companion
My phone hanged when listening to the music and when I force restarted the unknown baseband showed up. While flashing I got the baseband back after flashing .518 however it hanged again after two days and I lost the BB
Now I am struck in boot loops on .534 and .518 both. I can boot into .290 successfully. Can someone please guide me to the correct method of restoring my IMEI permanently.
P.S. As per my short experience with C6903, I believe something stops the boot of .534 and .518 after first boot. Means I was not able to boot into .534 but accidentally when I flashed .518, my phone booted successfully. However now I am unable to boot into .518. May be I am missing the piece of puzzle that an expert can provide.
Thanks in advance~

Thanks for your tip but I have already tried and still get struck in bootloop.
No .534 FTF has booted until now and I have used 6 of them already...
An update is that I have rooted 4.4.4 and installed recovery...
can someone tell me where can I get .534 zip to flash as the files I have are giving me verification error on TWRP.
Thanks in advance...
I have tried to use NUT fix but the files are not available for downloading.

Hi again, Really appreciate your help.
I have tried flashing a number of files but still in vain. What I really can't understand is .518 was the last 4.2.2 rom that booted successfully on my phone and brought my baseband back. Now .534 and .518 are both ending in a bootloop at Sony animation Really driving me crazy...
As a side note, can you tell me if the modem files in the link below are useful for this issue?

I need to fix my baseband issue. That can only be done with JB.

Thx for the tip but its not working.
My SIm was only detected once thats when I installed .518 but it lasted for a day and got held. When I force restarted the phone it was again missing baseband.
Now it isnt booting into .518 or .534.
Experts am I asking something that is un-do-able...
Guys shall I give up fixing this phone
I loved this dead beauty...
Hi, tried to flash with different cables as I don't have Sony original cable with me but the results are still the same. No luck with .534 and baseband is still unknown...
I understand this is a free community and people are free to determine if they wanna help someone or not. However I just wanna know if this is repairable or shall I just forget about repairing it. Any inputs will be highly appreciated.

I have realized that the phone does not shuts down with the power button in any bootable rom. Also sometimes the baseband does appear soon after installation but it disappears as sim is inserted. Can someone plz help me understand whats going wrong. I really love this phone...
