Hi, I have a Galaxy S3 GT i9300. I ordered it online, probably came from Germany since it came with a bunch of paper in German.
Anyway, I live in Portugal, and my carrier is TMN, and I'm really confused on how to root it, and unlocking the bootloader, which I don't know if it's really necessary or not, and then the ROM, which I'll bring up in a moment.
I updated all the way up to 4.1.2 now this is what I want to know:
1. The easiest way to root, I have questions about this cause there are so many ways, and I don't know which one is the best, or the right one cause I don't know if it's unlocked or not, but I'm guessing it is since I'm using a TMN (portuguese carrier) Sim card.
2. Do I need to unlock bootloader? If so, what's the easiest way?
3. Now I'd like to know of a stable ROM, preferably with 4.2.1, or 4.1.2, also I'd like to know if there is any way I could keep the Samsung Apps, and if not, if there is a way to get them back. All in all, I want a clean, fast and stable ROM.
Thank you all.

i would have thought you would root it exactly the same as you would with all other i9300 devices, with cf auto root (http://forum.xda-developers.com/showthread.php?t=1957273) however it doesnt install a custom recovery which you need to install roms. for that a good option is phillz touch (http://forum.xda-developers.com/showthread.php?t=2002953) which is based on cwm after rooting while on android 4.1.2 there is normally a red exclamation mark in the top left corner on boot. this is due to a new bootloader which sammy introduced to help them find phones that have been rooted and sent in for repair. the way arround this is to download the old ice cream sandwich bootloader (i dont have the link but im sure you can find it, i forgot where i downloaded it from sorry ) you may not need this or not be bothered about this so its your choice as for rom it depends on weather your looking for vanilla android or a samsung based rom. however there are no perfect rom it is purely based on your own opinion although a widely used and stable vanilla rom is cyanogen mod (http://forum.xda-developers.com/showthread.php?t=1779426) and most sammy roms are stable as they are not really altered much from stock however i use android revolution and have had no issues with it (http://forum.xda-developers.com/showthread.php?t=1797334). hope i helped in some way and i hope that what i said isnt too confusing thank you for reading
why does everyone want being spoonfed? what happened to good ol' searching? you're asking the most basic questions, do you really think they haven't been answered?
and asking for a clran/stable/good rom is against the rules

No best no right you pick a method .
2. Do I need to unlock bootloader? If so, what's the easiest way?
So you dont even bother to read the basic faqs and guides .
3. Now I'd like to know of a stable ROM, preferably with 4.2.1, or 4.1.2, also I'd like to know if there is any way I could keep the Samsung Apps, and if not, if there is a way to get them back. All in all, I want a clean, fast and stable ROM.
BEST ROM posts are banned but you wont know have you have not bothered to read the rules or the faqs and guides .

Holla guys I've recently have an s3.. wonderful device, seriously, but I'm very regretful as regards the SDS issue.. unfortunately my device seems to have the "affected chip" but I love Android world and I can't stay without modding something! the problem, as I have seen, seems to be solved until fws released from 4.1.2... To be more sure, I upgraded my phone to 4.3 stock yesterday and now the fw mounted is the XXUGMK6. My phone is NOT rooted and it is branded Vodafone. In this situation the device should be "covered" (hopefully, this damned issue it's a very bad thing )... however, as I said upon, I want to install something new to speed up this wonderful device.
So let's go straight to the point: what are the bootloader, recovery and rom that have the fws fixed for SDS? What are the best ones IN THIS SENSE? (not in absolutely sense, obviously, because each bl, rec & rom is simply best until it's cooked in my opinion )
Moreover, should I remove brand before installing something? Could you tell me precise steps to do kindly?
I'll be very grateful to everyone can answer my question, really
Oh, I almost forgot: I'd like to taste the speed of KitKat is there any fix or we must wait a Samsung official release??
No one can help me?
Inviato dal mio GT-I9300 utilizzando Tapatalk
Everything built recently (not sure how long) has the fix. Any KitKat build will have the fix, and both newest builds of CWM and TWRP do as well.
Basically, flash anything new and you're fine.

i have the sds chip also i actually had a fright a few months back when i woke up to my phone boot looping and anyway what i get to understand is that once u have a recovery and a bootloader with the latest fix u will be find... i use to use cwm thats before it bootlooped then i switched to philz cwm both right now are suppose to have the sds fix so basically after that flash any rom u want ..cause all the modern roms from 4.2 up as iv observed have the fix and havent given me any sds problem.
Wow guys! Your answers were so great! I can't wait anymore... I start to flash.. "suddenly" ahahah many thanks, I really appreciate your help
Another last question: I must remove brand (flashing no-brand fmw from Sammobile) before flashing custom stuff, right?
I must say "up" otherwise many questions in this section will completely hide mine
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

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.

We are in the "soon" state from january, first with 5.0 and now with 5.1 and this phone is pratically becoming "motorola moto indians" considering that only them are getting soak and/or updates, so, what do you guys think? wait or go for a custom? i'd flash a custom now but i read everywhere people that have problems going back to stock after flashing custom roms on the E and someone says that this is the easiest phone to brick (why? dunno)
ps. yeah i really want to change, stock 4.4.4 it's giving me problems and since i need to reset soon i want to upgrade.

That someone is probably me I guess? Well ya, some devices are unbrickable but some devices like this one are easily brickable [emoji20] One bad move and you would end up with a bricked device with no rescue. There's more that can happen, unfortunately Please be careful, do not depend on OTAs much because they are the most famous sources of bricks. Always prefer flashing ROMs via TWRP latest. Also, if you want stock, ask someone to upload their TWRP backup of system and boot partitions if you already have messed up with OTAs before because at this point of time, we really don't know which OTA can brick the device so please stay away from them and prefer custom ROMs or TWRP nandroid backups [emoji55]
if i flash a custom rom like cm or whatever, will be easy to go back to stock 5.1? (when the update will be officially available)

Once the factory image is released, I guess it'll be easy to flash it via fastboot.
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.)
