Hi Guys,
Please kindly help where you can,
I'm using an Xperia Z ultra (C6833) , since I have updated it from kit kat 4.4.4 to lollipop 5.1.1 in December 2015 the screen has been flickering so badly. I tried switching off the adaptive brightness option as read through other forums and xdaforum but nothing helps. I've sent multiple emails to Sony thinking they would assist but all I got was to be referred to an authorised Sony repair centre. The phone works fine fewer times but most times it gives me headaches with flickering.
I tried downgrading twice using flashtool and ftf stock rom file but it was soft bricked, it bootloops forever. I had to repair using Sony companion suite 2.1 to get it working again but the problem persists.
I have tried all possible ways to fix the problem but I
The question I have...
1. I want to downgrade to kit kat 4.4.4 from lollipop 5.1.1 without rooting or unlocking bootloader, is that possible?
Please kindly HELP,

I got the new xperia C5 ultra which still hasn't received the lollipop 5.0.2
So I was eager to get as close to it as possible and ended up in a small problem.
What I did was install the launcher for xperia z3 running 5.0.2 as an update (thinking I can roll back"uninstall update"if there was a problem) and now it isn't working properly and I can't find a way to get the correct version back
Yes, I could factory reset the phone but I personally have tweaked it alot spending alot of time. I wouldn't want it to go for a waste
So please kindly help
Thanks in advance
Hi. I've bought an xperia z2 from a friend and i think i might have a big problem here. It keeps rebooting for no reason at random moments when i'm using it. It freezes like 3-4 sec and then it reboots. I'm really concerned about this problem... is this a software or a hardware problem and how can it be fixed? When I bought it the android version it came with was 5.1.1 and I flashed it now to 5.0.2 with no success. Also every incident is being reported in the software incidents but it is not shown any information about it. What can I do? I will be forever thankful if you can help me out!
check bootloader at first. It looks like software problem. Can you tell me which compilation you have?
I just flashed a few minutes ago official version 4.4.4 kitkat and I'm afraid to install any app at all...
Could you tell me where can i find the bootloader version please?
Also how can i upload a picture here? Thank you.

Hello everyone.
I am trying to find a way to root my Xperia Z Ultra which is a C6833 On Lollipop 5.1.1. The phone is already out of warranty, so there is no problem with invalidating my warranty. I have rooted other devices and put custom roms on them, but this phone has never been rooted. Is there a walkthrough to root this phone and put CWM recovery on to it? Also, what roms are available for this phone? The phone is network free, and I live in the UK, if that makes any difference. Thank you in advance for any help you can offer me.

After upgrading my M4 Aqua (E2303) to Marshmallow, I can't make or receive phone calls (except occasionally). I've tried repairing the MM install with Xperia Companion, but that doesn't help. Booting into safe mode doesn't help either.
According to the Sony forums, other people have had this problem as well, and there is no Sony solution forthcoming. One person has said that going back to Lollipop solved the problem. However, when looking into how to go back to Lollipop, apparently I need a Lollipop FTF file to use with Flashtools. But I can't find any for the M4, just Marshmallow ones. Does anyone know where one is to be found? Or has any other advice about fixing the call problem in Marshmallow? That would be much appreciated.
Actually, even a generic Lollipop version would do, I'd be quite happy to debrand at the same time.

Thanks for that. I'm still waiting to hear from Sony, to see what they say first, but I may have to use that.
I went back to Lollipop using Flashtools and a Lollipop FTF file I found on Xperia blog:
http://www.xperiablog.net/forum/resources/categories/xperia-m4-aqua.78/
The file I used was the one called 'E2303_26.1.A.2.167_R16A_UK Generic_1293-9369'.
All my problems have now gone away.
It's not easy working out exactly how to downgrade. The best instructions were probably these:

But there's quite a few complications, and I found reading around the web on this issue helped.
There is a risk involved. There's no guarantee it will work. You may end up bricking your phone. (But my phone had become pretty much useless anyway.)
Hi guys,
I upgraded my Sony LT25i to version 5.1.1 with CyanogenMod rom (cm-12.1-20150620-UNOFFICIAL-tsubasa), but since it randomly reboots and have other issues which i couldn't find solutions for (applications stops etc) I want to downgrade the version to how it was before. I took a backup of the phone before I started, but it seems like "Sony Bridge for Mac" application doesn't take a "full backup" (only images contacts and so on), so now I don't know how I can go back to Android version 4.3, cant even find original rom for my phone..
Where can I find the correct version for my Sony LT25i tsubasa? And how can I reinstall everything to stable version 4.3.?
As you might guess, I have no super skills on this, so I can honestly say that I am a noob. Please be kind =)
Big thanks in advance.
