Same here... didn't work for me either, except I started from my daily driver of .136 by NUT. :crying: I upgraded to the 97 recovery and couldn't get write permissions on System, maybe that was the deal breaker. Maybe stay with .94 and try again.

Started over from scratch at .154, rooted, custom recovery and restored backup in TWRP. I'll just wait for official NUT release of 6906 :fingers-crossed:
[Xperia Z1 Android Development] hush66:
Search Play Store for this app called SDFix by NextApp. It will help with the SD card restrictions on KitKat. But you must have root for it to work.
[Xperia Z1 Android Development] drsoran2:
That's the point. I don't have root with 4.4.2. but I had it with 4.2.2. and now I'm trying to get it back with 4.4.2 as well and then I can use this app.
[Xperia Z1 Android Development] rpcherrera:
You can untick the Data option in the Wipe section. But to be safe or for peace of mind do a full clean wipe. Backup your data now.
[Xperia Z1 Android Development] PherChe:
And if you change build.so (i dont remember the file name) you can change c6903 to c6906, right?
[Xperia Z1 Android Development] [Fenix]:
For example if you are using Windows 8 you can find some problem...try to flash the ftf on second post, when it loads on flashtool he wipe what is necessary... just leave the option as they are...when you are done and the system is loaded enable developer option and reboot the phone than try to connect it to PC and see if it is reconised...if yes proceed with root and recovery

Used the latest flashtool-0.9.15.0. I had done it twice and now back to 136 ROM and enjoy. Waiting for next kk version.

my Sg device: Z1 rooted136 ROM by NUT with 2.7.94 xzdualrecovery, mod by GavityBox 3.0.0. Samsung S2 standby for Z1 when Z1 no power.
[Xperia Z1 Android Development] drsoran2:
I've tried flashing NUTs 4.2 fts from the second post with flashtool without wiping (only Cache) and ended up in a bootloop.

I then flashed 4.4.2. back.

For some reason when I connect my phone to the computer via USB I can't copy the backed up apps from the "carbon" folder on the microsd (which I have backed up with the Helium app) to my PC. It's stuck on "calculating the estimate time".

I also can't copy the contents of the internal storage to my computer to have a backup. Same problem.

Lastly, the wireless connection with my PC under the "Xperia connectivity" tab is also not working. It says "can't configure network access on this device" or something.

So, without being able to make a proper backup I don't want to downgrade with wiping everything. And without wiping I can't downgrade because there's the bootloop again.

Therefore, I can't downgrade, root, install recovery and then follow the OP to have a rooted 4.4.2 firmware.

All of this because I'm trying to "fix" my sd card to the way it was before.
[Xperia Z1 Android Development] Black_halo:
tried that didnt work. it saved super user on my device but no root access
[Xperia Z1 Android Development] cgomezparra:
In theory yes, but when I try to put the original build.prop and reboot the phone it fails and enter in bootloop maybe editing the file and change all C6903 entries to C6906.
[Xperia Z1 Android Development] rpcherrera:
Sounds complicated. Do you have a card reader? You can just mount the sd then copy your backup
[Xperia Z1 Android Development] funky0308:
Uff...too many and and too long post to read...

I saw question - is it possible to downgrade to 4.2.2 from 681

The answer is - without any problems.

I did that few times and no bootloop or any problems...
[Xperia Z1 Android Development] PherChe:
Did you try it with a original kitkat's Build.prop?
[Xperia Z1 Android Development] drsoran2:
did you wipe when downgrading and upgrading later on or only partially or not at all?
[Xperia Z1 Android Development] xshunin:
I have more stuff to report from my daily usage. Although the mounting of /system does not work in the TWRP, it does in CWM so I can do backups there :D
[Xperia Z1 Android Development] funky0308:
If you know how to use adb and wipe only apps that are necessary you could downgrade without full wipe...

I don't do that...it's easier to wipe all and just set all over again...

Try to find tutorial for adb wiping and maybe you find something interesting...
[Xperia Z1 Android Development] drsoran2:
I've searched but couldn't find anything so far...

"Only wiping certain apps": Which ones would they be?

I can't imagine that wiping all and setting up again should be both easier and especially faster than downgrading and upgrading without full wipe, if that could be possible.
[Xperia Z1 Android Development] funky0308:
If I remember well - media app (walkman, album, mail, movies...)

Can't remember all...

I saw that one time but really can't remember procedure...

I'll try to find that and will let you know..

problem with unlocked bootloader

i have installed this firmware from .290 (rooted & unlocked bootloader), but i have problem with the camera.

I understand that people with LB does not have this problem.

Does relocking the bootloader while being on this firmware fix the problem or do i need to go back to original firmware (like .290 or .136) then relock the bootloader and install this firmware again???

(btw i don't have backup of my TA partition :( )
[Xperia Z1 Android Development] funky0308:
It's not important firmware to restore TA partitions backup...

But how do you plan to relock bootloader without TA part.backup?

Don't use from other device - you'll permanently brick device.
[Xperia Z1 Android Development] Black_halo:
Dont know if you've found the ftf for c6906 but here it is:

https://mega.co.nz/#!ZFdW3aJA!hsWlXbvZXa1yoKQVfjHt6H1M73xK_fAw5ucadGabBv4

and going to be honest I got desperate and exhausted every option i could think of to give me root on 4.4. after i tried putting the superuser files in the bin and xbin inside the ftf with 7zip. I flashed and to avail....i need your expertise. please can c6906 get the stripped ftf.

[MENTION=4904057][NUT][/MENTION]

hi mate...any news?

You found what causing mounting problems?

I noticed one thing - if I open recovery and go to "mount and storage" (very fast after TWRP openes) system mounts on start but it unmount very fast)
[Xperia Z1 Android Development] noobz1:
I think by using latest flashtool i can relock the bootloader(even though i can not restore DRM keys and as far as my understanding DRM keys are only used for warranty).

I read somewhere saying that we need to be on PURE STOCK KERNEL to be able to relock the bootloader. My doubt is,

is this a stock kernel or its been tweaked too much?? So that i ll be able to decide whether to relock it with the current firmware without any risk, otherwise i ll downgrade to official .290 or .136 and relock the bootloader.
[Xperia Z1 Android Development] funky0308:
If that works - great...

First time heard that but OK...

If I were you, I would flash official stock ftf and then tried that...
[Xperia Z1 Android Development] gregbradley:
This is not a stock kernel. In fact there is no kernel in this thread, just some deodexed system apps

As soon as a kernel is decompiled it is not stock, even if you do not tweak it and then recompile it wont work on a locked bootloader
[Xperia Z1 Android Development] noobz1:
The option- BLU (button) in Flashtool does this but i don't want to take risk :P

I hope NUT will fix this issue :) :)

oh fine ... thank you :)

Hello everybody.

So the Telcel's ROM 14.1.G.1.158 (my carrier) is here.

Like i said before, i installed it first because i need to be root first and to have TWRP (I was on 14.3.A.0.681 upgraded from PC Companion and is not rootable). The installed all the zip (i did not upgrade to 4.3 before, it was directly). Don't forget wipe.

after reboot its fine

Unfortunately I don't have the necessary knowledge or I would help him for sure =/
[Xperia Z1 Android Development] PherChe:
it does include it, the true is i forgot it but i think it has problems im not sure.
[Xperia Z1 Android Development] madsatan:

Hi there, just came here to say a thing or two ^^

First, i was trying to update with dualrecovery v2.7.95, i ended up with the "can't mount /system" issue at the end of the process then had to flash back to .534 then start the whole process again. And again it failed. Had to understand why. And after reading the whole thread here and a few pages on the dualrecovery thread i tried with v2.7.94 it worked well !:victory: Finally, the whole process went without any problem.

Now i'm on kitkat and on my way to press some thx buttons ;)

Probably a very stupid question:

Do I need the "XZlockeddualrecovery" to install the recovery via Windows or the "Z1 lockeddualrecovery"?

Since I have a Z1 and not a Xperia Z ("XZ") I assume I need the "Z1 locked dual recovery" but in the OP it says you need the "XZ locked dual recovery"

Which one is right or best to use?!

I flashed NUT's C6903_14.1.G.1.534 on C6902 from kitkat, now i am getting bootloops as well as reboots. Cant root the device with reboots. Can someone tell what to do now? If I flash generic C6902 14.1.G.1.534 will i lose my IMEI and will i get it back after flashing NUT's pre rooted 4.4.2?
[Xperia Z1 Android Development] funky0308:
Try to use recovery 92 (older one), I had same problems and flashing recovery 92 solved it.

Just flash 534 (you have link in OP for downgrading to 534 without losing IMEI).

But even if you lose IMEI, that's not problem if you not planning to stay on it...

Just flash 136 or 681 and you'll be fine... (your IMEI will be back)
[Xperia Z1 Android Development] mnsk:
I flashed the file from the OP's link but it is of C6903 534 and my device is C6902. Is there a link for c6902 534?
[Xperia Z1 Android Development] funky0308:
Yeah...now I saw you are using 02 device...

Then flash 534 fir your device, you'll lose root but that's not problem.

Root 534 and install recovery (this time try with version 92), flash 681 and stripped ftf.

You'll lose recovery ability to mount system so before you turn device off to flash kernel (stripped ftf), flash all your MODs you want to use...

I flashed newest recovery (97), font package, superSU fix and superSU update (1.93) and deodex patch (there's deodex patch for 02 somewhere on XDA)

Could someone open thread on general or maybe even better on Q&A so we could talk about all this there and use this thread to help NUT to find and fix rooting method/recovery for KK?
[Xperia Z1 Android Development] mnsk:
Ok i will download generic 534 for my device. I wasn't able to flash recovery since there was no root but i will try with version 92. One more thing can you provide the link for superSu fix and superSu update. Thanks!
