[Q] Please help. Phone from Hong Kong, can't update past 4.2.2. - Sony Xperia Z Ultra

Hey guys,
Thanks in advance for any help you can give on the subject.
I just bought a Sony Xperia Z Ultra from eBay, arrived a couple of days ago, in great working condition. The firmware installed is 4.2.2, and I can't upgrade past there.
I contacted Sony and they told me it's because the IMEI number puts it's origin in Hong Kong which is why I can't update it. The only thing I can do is contact Sony Hong Kong, and I'm having a difficult time doing so.
Does anyone have a fix or workaround for this situation?
I was thinking I could root it and put an upgraded version of android on there, but as I'm not sure how rooting works, I thought I'd ask if there were any alternative options.
At this point, I'm thinking I'm just going to have to send it back, reason being when I chose this phone, one of the main points was because of the soon to be released 5.0 update.
Thanks,

As far as I know you should be able to use flashtool and flash a stock ftf for your region, or wait for 5.0 to be released and then flash it.

Thank you for getting back to me.
I may wait for 5.0. I'll need to learn how to use a flashtool with android first.
Quick couple of questions. Would using a flashtool to flash a stock ftf require the phone to be rooted?
Also, do you know if there is anyway I could use the Google Play firmware on my non-Google play edition?

Flashtool does not require root. The GPe firmware has to be "ported" to run on Sony Z Ultra due to different partition sizes. For 4.4 there is the option to use it with locked or unlocked bootloader. For 5.0 it is only for unlocked bootloader.

Thank you again for getting back to me.
Do you know if there is a tutorial for both porting the GPe firmware and for installing 4.4 using a bootloader? As I'm not even sure where to start with this, I'm not even sure what the difference between a locked and unlocked bootloader is. But I don't want to use up all your time, so if you can point me in the right direction, I'd really appreciate it.
Thanks again,

It has already been ported here in this thread linked below, UB and LB are short for unlocked bootloader and locked bootloader. The second post has instructions for locked install, and a simple explanation of bootloader is a set of instructions for loading the kernel so locked will only load stock. The kernel is the interface between software and hardware as I understand it.

Thank you for all the information.
I've done a bit of research, and read through most of what you linked.
I'm slightly confused. As far as I understand it right now, if my bootloader is locked, I can only flash official ROMs. If my bootloader is unlocked, then I can flash any ROM I want, as long as it's compatible with my phone, but I will lose the Sony Bravia engine if I do so, is that correct? I'm not too bothered about this, just curious if this is true.
Where I am really confused, is the part where in the requirements of LB Rom Port, it said
"Be on 4.4.4 firmware (only .108)"
I'm currently stuck on 4.2, and can't get my phone to 4.4.4 with either the built in software or Sony Pc Companion. Is there a guide somewhere on how I can upgrade to 4.4.4 without using the two methods just mentioned?
I've also had a search and not been able to find a 5.0 GPe ROM Port either, guessing no one has bothered with it?
Thanks again,

I seem to have also lost the miracast screen mirroring after unlocking bootloader, if you root then back up the TA first it can be restored. I don't have any experience with pc companion, usually when it is mentioned it is because someone couldn't get it to work. In those instances flashtool is recommended to use. Here is a guide for flashtool. http://forum.xda-developers.com/showthread.php?t=2428319

I assume this one will be ok, though I'm unsure. My phones model number is C6833, and this was the only 14.4.A.0.108 ROM I could find, and as far as I've seen, that's the recommended one for 4.4.4, assuming I haven't done anything wrong.
And just double checking, do I Need to root the phone to put the 5.0 GPE port on?

I was able to use FlashTool to update the phone to the official 4.4.4 ROM, so that you very much for all your help.
I think I may just end up sticking with the Xperia ROM, in favor of rooting and installing a port. I'm actually really liking the 4.4.4 Xperia version.
Thank you very much for all your help, I really appreciate it, wouldn't of been able to do this without your help.

That's good that you got updated. If you decide later to try custom ROMs or the ports be sure to root, then backup the TA partition before unlocking the bootloader. If you wanted to stay on stock but add some customizations you could root and install xsposed framework modules.

[Q] Noob question: install custom rom / revert to stock

Hi all,
I'm quite new to the sony and android scene. My iphone 3GS broke down a while ago (actually I dropped it ) and I had it replaced by a Mini Pro.
I'm on the stock 2.3.4 rom and would like to test the miui version on this forum.
So, my question is simple: I need to unlock the bootloader to install a custom rom.
Can I revert to a stock rom (or upgrade to the new upcoming ics stock version) without loosing DRM etc?
And what's the procedure to do so?
you will have to follow this guide http://forum.xda-developers.com/showthread.php?t=1285285 that is the only way to unlock it without losing drm and the ability to officially update.
Looks quite scary stuff to me. Coming from a jailbroken iphone, it looks like this is a bit trickier. Thank you for the reply though
Another small question then: can I still upgrade to a stock rom version if I have unlocked the bootloader? (via an unofficial way that is)
yes you can, but if you unlock your bootloader the official way you are not going to be able to update using sony software.
and yeah it looks scary but it is easier than it looks.
Great, thanks for the info. I'll search around the forum for the unofficial unlock mechanisms and will have a try with them!

[Q] Google Play Edition firmware on Non-Google Play Edition?

Wondering if this is possible?
I have a C6806 through Bell. It however uses the Sony Branded ROM. Would this update work or are their hardware differences which would cause a brick?

Oh please read some threads in this great forum it got asked soo many times. To your question: No as of now this is not possible. And most likely making your device a regular GPe will not be possible too. A modified version of the rom will be available soonish

I purchased a c6806 from Bell about 3 weeks ago and would prefer to be on the GPe firmware, if possible. Under the Android development forum for the Xperia ZU, bigxie has posted a port of DooMLoRD's 4.4 ROM. With my unlockable bootloader, is it even possible for me to attempt to flash this rom? And if I do, will it mostly likely brick my device?

It does say unlocked in the OP of the thread, and needs either the stock GPE kernel or the modified GPE kernel. I dont believe that either will boot on a locked ZU

You're on Bell which means that Bell have locked the bootloader themselves. You can't unlock your bootloader, so you can't flash custom ROMs (including GPe). This might change in the future though (if some dev manages to crack it), but don't count on it.

[Q] Newbie asking for some guidance

Hi all, I am about to become the proud owner of a SXZ Ultra, and I was hoping someone might be kind enough to provide me with some links to the the most important info to help learn my way around this device. I have experience with Android but have no idea what to expect from the Sony UI nor the rooting procedure etc., so I would be grateful for some pointers to help minimize the learning curve and get the most out of the device as soon as possible. A quick search on the subject of rooting left me somewhat bemused...I am used to the SGA (Samsung Galaxy Ace), which was a totally different type of device with an entirely different procedure for flashing ROMs and rooting.
I have a specific question aside from that - I see that there is an IM750 MHL to HDMI adaptor available from Sony, but I would like to know if this is really necessary - has anyone had success with Miracast or Wifi Direct/DLNA connection with a smart TV so as to be able to send what I want to watch on the TV from the SXZU? I would prefer this to having to connect via HDMI because I have found that mini/micro HDMI connectors on tablets seem to be rather fragile to say the least, and it would also make far more sense for presentations. Thanks for your help.
MHL works well. Some people seem to have no issues with mirrorcast etc but others do...
For rooting read LordManhattan's guide and my downgrade guide both at the top of the general section.
The steps are more or less;
downgrade
Root
Backup TA
Unlock bootloader
Flash rom...
For stock sony firmware you can get the updates via PC companion [PCC] or use flashtool and flash FTF's

Thank you. The thing is that if possible I would like to avoid having to unlock the bootloader, but I need Root in order to use Titanium Backup and be able to flash an alternative recovery so I can use Online recovery tools. Forgive my ignorance, but is this possible? Ideally I would like to upgrade to KitKat then obtain Root and flash the TWRP/CWM twin recovery without unlocking the bootloader - it seems to me that there are several advantages to using the stock ROMs, particularly being able to recieve Sony upgrades, at least until they stop supporting the device.

Yes you can get away with not unlocking the BL, if you go that route you don't need to back up the TA either. You will still need to downgrade yo route though. There are several ROMs based on sony firmware, and to be honest will probably be better that pure stock. Some of the upgrades have worked on rooted phones others haven't

Thank you. Are any of those custom ROMs available with the latest Kit Kat release? I see that the SXZU is listed by Sony to receive this update, which is primarily why I didn't want to flash a custom ROM right away = and I would like to try Sony's stock configuration first. I have tried CM10, PAC ROM and others in my SGA and frankly I was underwhelmed for the most part, although with such a totally different device I might be pleasantly surprised...
Which ROM would you personally ally recommend?

Yes Sony has a 4.4.2 firmware out for the whole range. There is a rooted rom based on this that is very close to pure stock Sony I believe, and then there is Monix's ROM based on Sony's 4.4.2 release that gets good reviews - it is quite customised.
On the custom ROM front there are:
SlimKat - this is my preferred ROM but I'm having trouble building it for this device consistently
Carbon - this is my daily at the moment, I'm doing the unofficial builds of this for now
LiquidSmooth - this seems to get good reviews but doesn't look like it's been updated in about a month
PAC - I was using this for some time and was good
PA - as above
CM11 - Has it's fans and most of the other ROMs use at least some parts of it and it's device tree
AOSP - Don't know what that is up to, not used it
AOKP - as above
PAC - I was using this for some time and was good
PA - as above
Then there is the GPe port that many seen to love

MM problems - can I get back to Loliipop?

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:
http://www.xperiablog.net/2016/03/12/install-xperia-marshmallow-using-flashtool-and-xperifirm-guide/
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.)

Is my z2 compatible for rooting?

Ok so i'm kind of new to the android world after a long time being on iphone and for the past two days I have been trying to figure out how exactly to root and all this stuff(you know, jailbreak). So far I have had no luck or clue what I'm doing wrong or if I'm missing something. Unfortunately, I don't have much details since I been trying and researching so much that I don't know where to start so I would rather just post about what version and whatnot I'm running on my sony xperia z2 and if someone could tell me if I can actually root it and link me to a thread that shows how to root this I would be grateful.
Sony Xperia z2 Model D6503
Android version 6.0.1
Kernel version 3.4.0-perf
Build 23.5.A.1.291
Also I'm not sure if this matters but it's locked to bellmobility.
*edit: oh and bootloader is locked.

I thiks you can root your device, try to install recovery first (twpr for exemple)
Than you should downgrade your kernel, and update once again to .291
flash SuperSu via recovery voilĂ .
Do some search on the forum, good luck :good:
