Need help rooting new tablet - Xperia Z2 Tablet Q&A, Help & Troubleshooting

I just had my z2 tablet replaced under warranty with my carrier (previous tablet just would no longer turn on)
my old tablet was rooted, the replacement I just received is already running the latest update, i can find info on rooting old versions, nothing for the new one (at least that i understand)
tablet details
Model No. SGP521
android version. 5.1.1
build no. 23.4.A.0.546
any instructions or assistance on this would be hugely appreciated
(please assume i am a complete novice when it comes to this and need thorough explanations for the process, because that is about where my knowledge base stands)
my reason for rooting is that i have an SD card which before i was using to store and run apps from
would like to be able to do that again
thanks

Well first thing you would need to do is flash an older version with flashtool (don't mistake it with Sony flashtool, that's the wrong one)
After you've done that you can root it, install recovery, and update to a newer version using update zip.
All the howto's to do this are already on xda multiple times. Just use the search function.

[q] what apps are safe to remove after root

Hi
I'm still quite new to rooting and moddifying my phone so any help would be much appreciated.
Before the gingerbread update come out for my X10i I had rooted my own phone along with a few of my mates phones by folllowing the flashtool guide here http://forum.xda-developers.com/showthread.php?t=928343. I also installed the JiT etc to try getting better proformance from my own phone.
Since the update I have gone back to stock so I could update my phone and now have the latest version of flashtool, but waited before rooting anything.
Can anyone supply a list of the stock apps that are safe to remove as I am sure there is probably more now since the old flashtool. Also any ideas on how to get more proformance from my stock ROM (without using a moddified ROM as I am not confident enough to play about with those yet) will be much appreciated
Find on General section, i ever seen one thread talking about this.
It explain every apps you can remove.

Rooting SGPT211US/S

I recently picked up a Sony Tablet P model SGPT211US/S. It's the AT&T model, I got a really good deal on it but I've been struggling to root it. As best I can tell I've installed the drivers and the adb package. From there I've tried the all in one root tool with little luck. The tablet is running 3.2.1 and wont find any up dates to ICS.
I've done some research and there are 2 things I've found. A few times I've come across some people talking about un-rootable devices. Going from a process of elimination I'm assuming the SGPT211US/S might be one of them?
I'm extremely familiar with rooting on the Galaxy Tab and S devices. Is there some sort of similar method to Odin an ICS Firmware to the Tablet P (SGPT211US/S)? I'm a little lost here. I've even read that ICS wont come to the AT&T version of the P. I don't need the data connection and from what I've read you need to root in order to flash custom roms, which has been my experience with Samsung devices. Is there a method to flashing a stock or modified stock rom on the Tablet P similar to odin flashing to a Samsung device? Any help would be great, this one is really confusing me.

If there is no root obtained from using AIO then you are out of luck. Can you tell me your build number ie 3.2.1R2 kernel 10, from settings about. Many users have the kernel 10 issue where the exploit has been patched and we are currently awaiting a new root method.
What was the nbx02_XXX number from system/build.prop i assume it is nbx02_001. Which is normal US. Maybe AT&T have disabled OTA updates? In which case if you can find an update on the web you can apply it through recovery.

First off I appreciate the help!
Honeycomb
3.2.1
Kernel version
2.6.36.3
I'm not sure I fully follow the nb info. I don't see it.
I do see integ-build5 #1after the kernel version.
Under build number
THMAAS0015400
Baseband
R4A02
Maybe this will help determine if I'm unable to root? I might try the update through recovery, however I've read that might make it so I cant root?

Ok so you are what we call kernel5 so you should be able to root, unless AT&T have patched the root exploit. Can you try the attached program, it is the original exploit that is in the AIO tool but may help.
same tab here, it's possible to install ics, even loosing the at&t branding? I don't care

Stifilz, I had my hopes up reading your posts here (http://forum.xda-developers.com/showthread.php?t=1592663&page=2) that I might be able to update to 3.2.1 and then root with AIO. When I tried installing the suggested rom signed-nbx03_006-ota-0042.004.zip using recovery, I got the following error:
Erohibit update as a result of checking version or base sku
Do you think this is because I'm currently on a 3.2 base10 kernel, because I'm trying to install a French ROM on a US tablet, or because it is a Wifi+3G ROM and this is a Wifi-only tablet? I only tried this version because it is what you suggested in another post. Is there a US Wifi-only, non-base10 version to try instead? Is there a way to tell the kernel version of a .zip without flashing it?
My tablet info is:
Model: SGPT112US/S
Android Version: 3.2
Kernel Version: 2.6.36.3 [email protected] #1
Build Number: 1.10.001100001
Best Regards.

I was able to successfully update to 3.2.1 build 5 using signed-nbx03_001-ota-0042.001.zip and then root with AIO. At least the script completed, but I'm not sure how to tell if it succeeded or not.

Little help, please
I have the same tablet P (AT&T) as the original post... About screen shows it's also build5.
I was successful using the AIO to achieve root on the Honeycomb it came with, but trying to update to ICS has gotten me nowhere.
I thought perhaps using the AIO's Region Changer combined with one of the OTA update files I found in another thread would be enough. It failed with the message about 'prohibit update because of base sku'. I then tried various combinations of fiddling with the settings on the Aio and downloading other files from different threads with no luck. Even tried that "nbx03" update even though I know this one is nbx02 and being a noob I haven't the slightest idea how to fool the device into using that update.
I'm ok with using what I have if there's really no way to upgrade, but it seems like with all the different options there SHOULD be some way. Any ideas? I'd appreciate any advice you have.
Thanks in advance.

[Q] asus tf201 with twrp/android problem

i recently bought a asus tf201 on ebay and the android version on it is 4.0.3. As i found out later, it's also been unlocked. i have twrp v.2.2.1 installed and i want to install the latest version of android. i tried downloading the latest version of android from the asus website to my sd card and followed the instruction. but when i get to the twrp interface, i don't know how to get the update installed. it seems like it does not detect any data on my sd card. any help would be greatly appreciated. Bear in mind that i'm an absolute noob and i don't even know what "unlocking" a tablet means.
Thanks a lot for your time guys.
If your ASUS is unlocked I would not instal anything from ASUS. If you want to update you are going to have to flash a ROM, and if you are still looking to update to 4.2 you are going to have to flash the JB bootloader.
I would suggest browsing the developers forum for a ROM you might like and CAREFULLY read the posts about upgrading.

[Q] Updating Custom ROM via Built-in Software Update

I have searched for this simple question, but have yet to find an answer.
I have a custom Android 4.2.2 ROM (for my SGH-I337M) (I cannot provide a link as this is my first post) and I have received a notification asking me to update to the latest version on Android (4.3). I would, but I'm not sure if it is safe to do so via this method. The main reason I have not done this is because after installing this ROM, my model number changed for SGH-I337M to GT-i9505. By doing this, my reasoning is that the update downloaded is for the GT-i9505 and may not be compatible.
Now for the question, is it safe to update my phone this way?
The main reason I'm not using the Android 4.3 link is that my Mobile Network State will not change from Disconnected in that ROM.
While I'm at it I may as well ask this. If I do update this way, and it doesn't work, would a simply recovery from TWRP be OK?
Thanks in advance, and my apologies if I have posted this in the wrong section, I could not find one that was specific to my issue.

[Q] Please help. Phone from Hong Kong, can't update past 4.2.2.

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.

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?

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.

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.
