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!

well the only unofficial way is by test point (the link i posted before) but it's good to hear you want to search anything else let me know!
Hello there, how are you?
My problem is, I received an Y300 as a gift, haven't yet received it but I want to prepare the necessary things to root it and install custom roms on it. No, this isn't the first phone I install a custom rom to, as I have already played with an Optimus L5 of a friend. Could you please answer this questions?
a) How do I root the phone and install CWM or other recovery? I have found many tutorials but they are confusing, and require waiting for 2-3 days for the code to unlock the bootloader. In case you need to know, it probably is the normal Y300, the international one, so no Asian Model
b) How many ROMS are there for this phone? I like Cyanogenmod and stock roms the most, I can barely stand the stock rom in the phone, so I would like to install a new ROM on it ASAP.
c) By flashing the new ROM, do I lose IMEI or something like that (EFS Folder in Samsung phones)? If so, how can I back it up?
Thanks for your help

Here is a GUIDE to unlock the bootloader and root your phone
Thanks, LS.xD
This was all I needed, I've found a CM11 Rom in the Modaco forums, hope it works well. Just got to wait until I get the phone
Okay, so I downloaded the latest nighly of the ROM, but it appears that CM11 is not very stable and has many problems with SystemUI (statusbar) and other things. Aren't there any ROMS for the Y300 on XDA? Also, will I lose my network connectivity if I do the wipes (data,cache, dalvik cache)?
Again, thanks for all your help, I appreciate it
EDIT: Found CM10.1 here in XDA but it redirected me to Modaco, however it is quite stable, downloading now. So which wipes do I have to do, in order to get everything smooth? Also, as I said will I lose my network connectivity or IMEI if I do these wipes, or I can do this without worrying
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.

This thread is up to date if you wish to read up on rooting and unlocking methods. Please don't hesitate to ask questions as it would be better than stumbling into a mess that could be avoided.

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?

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
And link for 5.0 GPe port.

Thank you for the links, again, much appreciated.
I was able to find an official thread for Sony Roms, and think I've found the ROM I need to upgrade to 4.4.4.
http://forum.xda-developers.com/showthread.php?t=2453921
STOCK ROM] [FTF] Xperia Z Ultra (C6833) 14.4.A.0.108 "US RETAIL"
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?
Thanks,

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.

hi there ppl,
im new to this device, just got it few days ago, but my model is the 4g/LTE/ G7105. and it comes with JB 4.3
so i've search google, you tube, xda, and few more forums and found nothing on how to root my device. i know that there is a way to flash stock KK 4.4.2 firmware of other region from sammobile website.
i really dont care about the warrenty issue, mostly i wish to debloat the stock rom and flash custom recovery.
but i have few question if someone can help
1. i rather stay with JB with this device, so if anyone have this device G7105 rooting methood and did manage to root it pls share .
2.if i do decide to flash stock KK what happens with knoks, will it have effect on device (except the ticker which i dont mind) if i want to flash stock JB back ?
3. if i flash stock KK of region like france germany or greece, and my region is israel, will it have effect on my 4g/LTE connection and other network and gps problem?
4. last question, can i change modem if the above question mean i do have problems ?
i have galaxy s3 also but i was a lot easier to handle rooting, and since its a bit of different ways i dont like to mess hardbrick my device already.
thanks for all helpers
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 voilà.
Do some search on the forum, good luck :good:
