Hello,
I just purchased a Sony Xperia Z2 32GB Tablet. I don't have Verizon, and since it is Wifi, I thought I would be able to use it just for Wifi. Well, I can use it for Wifi but I cannot update. I keep getting an error message. So, I think I just wasted a bunch of money, since this will be of no use to me now.
Do any of you have any experience to help me out? I would surely appreciate it. I don't know too much about this stuff.
Thank you in advance for any and all help!
What error message are you getting.
You do have a reliable connection?
Which firmware is on your tablet now?
Why would it be useless? There is no critical feature in 5.02 lollipop.

Thank you for your reply!
When I go to Settings > System Updates, I get "Error during DM session".
Yes, I have a very good connection on 5GHz and a very good ASUS router. I am next to the router and my network speeds are +75 Mbps.
I cannot seem to find and install PS4 Remote Play in the Google Store. That is one of the main reasons I bought it. Plus, I like to be updated to the latest version.

You said you use Wifi which is fine, but the tablet still supports LTE.

Thank you, but that did not work. I don't have a carrier. This device is strictly wifi and will not do a system update. It is stuck at 4.4.2. I really do not know what to do now. After researching, it seems that I am out the money I spent.

I seriously doubt that you have a paperweight. Have you looked into doing the update via PC Companion instead of WiFi. If all else fails, you can flash the generic Sony firmware (FTF). It wont root your tablet, but it will wipe it and bring it back to factory state like if it was being turned on for the very first time. I don't know your level of comfort but Sony tablets are pretty simple to understand ...as long as you're ready to do a little homework. Lots of Verizon customers are *****in about that error you got...your tablet isn't broken or anything

Thank you for your reply, again!
The tablet is set to factory settings right now, it is just that it is Verizon's factory settings. If I did the FTF, will it wipe out the Verizon stuff and give me the ability to update to the latest Android version? I do not know too much about tablets, but I will certainly be willing to give anything a shot. I really want it to work (well, maybe work is the wrong term since it is a running perfect, really) with the newest update.
Would you be willing to point me in the right direction, or give me a few pointers?
Thank you very much!

When going to settings >> About tablet ... What's your model number.
You could download the generic firmware from Sony for your particular model number and flash it using Flashtool. IT will wipe the Verizon image and load the Sony image fresh.

My model number is SGP561. So, if I were to do that, I could then update the OS and it would be rid of Verizon's junk? That would be amazing!

My files do not look anything like the files in tutorials, and I keep getting stuck on "Please move C:Flashtool/firmwares content to..." It will not let me do anything else. I will keep trying, though.

You really need to move all the FTF files from the old directory to the new directory or the message wont go away. Also install the drivers for your tablet. The exe for the drivers is inside the install directory of flashtool. I cant give you the exact path as my Flashtool is installed on a different computer. I don't believe you need Java installed.

I have installed the drivers, but I keep getting "Drivers need to be installed for connected device." Do I need to do something else? I have the tablet off, I hold down the volume down button and plug it in. Then, in Flashtools, I receive that error I posted above.
I fixed the driver problem and everything installed from FlashTool, but I still have Verizon stuff on here.

That's extremely strange, which firmware did you download?? Did it flash successfully, after the flash did the tablet take a good 5-10 min to reboot. Did you build your own FTF or downloaded another one...something is definitely not right..
The tablet does take a good 7-10 min to flash properly. image.sin is the longest.

Flashtools said it flashed successfully, but it did not go through a long time load before it rebooted. I am using Selected Bundle for Sony Xperia Z2 Tablet (SGP561). FW release : 23.0.1.E.0.208. Customization : USA. I followed the tutorials and created my own FTF. Do I have to check anything else other than the suff in Flashmode? On the screen while I am flashing in Androxyde, it reads "Upgrading, do not disconnect device from PC. Software status: Official". It says that I can unplug it, but the tablet still reads, "Upgrading, do not disconnect device from PC. Software status: Official".
After that is complete, I unplug, restart and it splashes to Verizon logo and all of the bloatware is still there and cannot update the system. I am stuck! Am I able to do this on a Verizon tablet?

It shouldn't make a difference, its Sony tablet first...Verizon just uploaded their own customized firmware. I flash my Sony phones and tablets a billion times, I don't recall ever seeing "Software status : official".
You said you were on 4.4.2 but if you flashed successfully, 23.0.1.E.0.208 is 4.4.4 ...does your tablet reflect the new firmware?

Actually, it is saying 4.4.4, but it is pretty much just doing a factory reset. Each time I flash it, it just resets and makes me go through the setup prompts and Verizon stuff everywhere.
Is it possible to use a different file from XperiFirm? I have the SGP561, but can I use the SGP512? They have a US version in the list. Do I need the LTE version?

Hello everybody!
I am starting this new thread to try compile a simple to follow and reasonably written complete guide for rooting an Xperia Neo 2.3.3. I am doing this because, although there are enough information and software on this forum and on the internet in general, these are not really structured and gathered in a way that a non-experienced user (a.k.a. "noob") can easily manage, and the process of rooting 2.3.3. is a bit more complicated than 2.3.2 with Gingerbreak for instance.
This guide is for Xperia Neo running Android 2.3.3 with locked bootloader. Other devices with 2.3.3. might be rooted in a similar fashion.
Update: 2.3.4. for the Neo is out. Everything here still works as described with the difference that you get the latest 2.3.4 when updating OTA.
WARNING: some users reported that after downgrading from 2.3.4 to 2.3.2 in order to root, the battery meter showed 0%. I am not yet aware of a solution to this problem. So beware if your Neo already has the latest version.
Warning: Neither myself, nor anyone else but YOU is responsible if you damage your phone in any way or lose any information after trying to root your phone by folowing this guide! Also note that your warranty will expire when you root. However, unrooting should be possible, in principle.
--- Guide start ---
1. Back up your data. You could do this using an app called Backup Master from the Android Market. Additionally, I had my contacts and calendar synchronized with my Google account. SMS messages were not properly backed up, but I didn't care about them anyway. If you do care, you might want to save them to your SD card, using the built-in option or just use another app. Also make sure your battery is at least half charged before starting.
2. Download FlashTool from here or directly here. Install it by simply unpacking it somewhere.
3. Download the generic firmware 2.3.2 from here or directly here. You do this because Gingerbreak (will come to that) uses a security vulnerability to gain root rights in 2.3.2. that has been fixed with the new 2.3.3. Extract the .ftf file from the .rar archive you just downloaded to the sub-folder "firmwares" of your Flashtools installation from step 2. (You might need WinRar for extracting)
4. Go to your Flashtool installation to the folder "drivers" and install ggsetup-2.2.0.10.exe. Download the USB drivers for your Neo from here. Unpack the contents of the archived folder "amd64" (if on Windows 64) or "i386" (if on Windows 32) to the folder "amd64" or "x86" respectively of the installation folder of Gordons Gate. The path might be something like "c:\Program Files (x86)\Sony Ericsson\Gordons Gate\". Run DPInst.exe to install the drivers.
Alternatively to this step, I think you could install the drivers by just installing PCCompanion and plugging in your phone, but I did it the hard way.
5. Run the file X10FlashTool.exe; click Flash; you should see the firmware you downloaded in step 3 in the appearing window if you extracted it correctly; click OK (I recommend you leave the option "wipe data" checked, although some users reported that it worked for them even without wiping the data); follow the instructions (note that the back button on the Neo is on the other side as pictured); the flashing should take no more than a couple of minutes; start your phone - this will take a bit longer the first time. If after the reboot the battery meter is showing 1%, shut down and take out the battery for a minute, then boot up again.
6. Get Gingerbreak from here of directly here. This is the exploit that actually roots the phone. Copy it to your phone and install. You can do this a number of ways. For example: install ES File Explorer from the Android Market, access your PC via WLAN with it and install it directly from there. You will be prompted to change the setting to allow the installation of apps from unknown sources in case you didn't change it already. Also allow USB-debugging in the same settings menu under "developer".
7. Run Gingerbreak and tap "root device". This shouldn't take more than a couple of minutes, although some users reported it taking hours. If it is taking very long, you might want to try inserting another SD card and repeating the attempt. When it's done, it will reboot. Now you have a rooted 2.3.2. You can check this by installing the app "root checker" from the Android Market. When you start "root checker" you will be asked by an app called "superuser" if you want to grant root access to this program. This "superuser" app was installed by Gingerbreak after rooting and manages which program has root permissions.
8. Now before doing anything, go to settings>info>software update> update now and get the new Android 2.3.3 OTA (= over the air, i.e. via WLAN or 3G). Do not do this via your PC, because you will unroot the phone. There have been a lot of problems reported with this step. If right after you tap "update now" you get the message "unable to connect" try shutting down, waiting a minute and booting up again or also try setting the date and time to the correct values, in case you have something like 01 Jan 1980. Other users said, it just took a lot of attempts before it worked and that the problem might be with the SonyEricsson servers... If after the update was downloaded you get some kind of error message like "cannot update" it might be because you did some changes to system files or possibly you used a non-original firmware in step 3.
After the update was done, check again for root access with the "root checker"
9. Restore the data you backed up in step 1 and enjoy.
Update: I managed to update to 2.3.4. Unfortunately I could not simply update OTA from my rooted 2.3.3. I kept getting an error message after downloading the update, probably because I had changed system files. So I did all the above steps again, with the difference that in step 8 I got the 2.3.4. from the SE server.

A similar guide/tutorial/how-to has been posted before (Here). Perhaps not as detailed as yours but nonetheless, it's been done. And do give credit to the necessary people.
But good job on taking the time and writing this up. I'm sure a lot of Neo users will appreciate it.
Cheers!

Actually, I did link directly to the thread you wrote, because it was one of my starting points. And to be rigorous, the steps enumerated there are from here, but with the firmware for Neo. The real credit goes to the programmers of Gingerbreak, Flashtool etc.
Like I said, I was just gathering information and detailing them, I don't take credit for anything other than taking the time to write the post.
Yup, I had actually included that initially i.e. that most of us already know these steps from the original thread but then wanted to give you credit for doing what you did.
And when I said give credit where it is due, I meant the actual people behind the programs and kistigun for his tutorial.
guys after i root my neo according to this guide the ota firmware i get will be unbranded? right?
By the way thanks for the guide, i might use it one day after i gain more knowledge about those things...
If you've flashed the generic firmware, then yes, you would be unbranded BUT you will still be locked to your network until you purchase the unlock key.
Unbranding would remove all your network specific apps (part of bloatware).

An OTA update won't remove the branding, but flashing will. It's what I describe in step 5.
I was just like you a couple of days ago, but I managed to learn all this over the weekend and did all I described here. (and a few things more ) Don't rush into it. Read everything coherent and helpful you can find first.

ok i think i understand now, but just to clarify:
if i flash generic (unbranded?) and then do the OTA or Pc Companion update, the update i get will also be unbranded?.
also will all the future updates be unbranded too?
Another question: since my neo is Irish Vodafone branded phone, which generic software i should flash in step 5?
Thanks a lot for help and please do not get annoyed by my questions as i am totally noob when it comes to those things, also sorry for my poor English...

The answer should be yes to both questions. Once you've debranded your phone, it will not get "rebranded" (except if you flash it with a branded firmware). The generic firmware linked here is of course without any branding.

You could use the generic one, but you will lose the branding. I'm guessing you don't have a problem with that.

hehe yes people in general speak English here in Ireland but lets not forget there are thousands of emigrants from around the world living here too, i am one of them
Can you please also write which generic firmware should i flash, UK, World or any other? (perhaps there is IE one?), and will it affect the frequency of getting future official updates from SE? (yes i want to get rid of Vodafone from my phone and stay with a 100% SE official firmware).
Thanks
Once you flash a generic firmware, future updates will all be generic updates as well.
Some of the plus points that I can see of having a generic firmware is that
a) updates are rolled out faster (as compared to branded firmware).
b) you get rid of a lot of junk that network providers seem to put in i.e. bloatware.
OK I am now on generic, unbranded Global International 1247-0875_R11C , of course 2.3.3, however I did not root my phone and used SEUS instead OTA.
Thanks a lot Vorsprung and others for help

Open the dialer and enter *#06#. A new window with a bunch of numbers should pop up. If it says "0" or "0000", your IMEI is gone, and we'll take it from there.

I see, so i'm assuming that you've been on 290 and then downgraded to 257 or 532? If yes, that's why you've lost your IMEI. You can easily fix this by updating to 290 again, or flash NUT's 532 version in Flashtool.

NUTS 532 sounds interesting. Does it have support for init.d and so on?
Can i flash cwm to boot after? My aim is to become on latest stock but rooted. Why? Is because i purchased a sony original miracast device and i would like that to work...
Suggest?

Yup, it supports init.d.
It has dual-recovery installed as default, so you can either flash that one and stay fully rooted on 532 (with IMEI), or you can jump straight to 290, but then you'll have to flash it in Flashtool (so you get the latest baseband), and you'll have to root it yourself and install recovery.

The NUT 532 ROM is a Recovery file, so just flash it in recovery like you usually do, and you should in theory get your IMEI back. If not, flash a stock 290 FTF in Flashtool.
I have Miracast working on .136
It never worked on prior firmware - don't know if that was the tv's fault or the phone.
Sitting duck again
I tried flashing the NUT 532 and all seemed ok until i power the device up. I get thousands of force close to the system ui. Practically rendered my ZU useless. Does anybody recognize this issue? I tried a factory reset as my hands had to dance in order to reset it. Right now i dont know what fw oi am on but as i said the phone is uselesss.

Did you do a full wipe after flashing? If not, you should've done that. Also, no reason to panic. I understand why you might be, and i've been in much worse situations than this a couple of times, but it's nothing we can't solve. It takes some effort to hard brick a Sony. It just depends on how far you're willing to go to get it up and running. The easiest way would be to just flash 290 in Flashtool and be done with it. That way you'll have a fully funtional phone again with IMEI, and you can do the rooting later on when you have a system that's actually functioning correctly. Get your stress levels down again and root and what not when you have full control over your phone again
I'm in Norway btw, so since we're in the same time zone, i can help you out tomorrow after school/work if you need it.

What I would do is do a flash of the FTF in my guide on downgrading the ZU/recoverinf the IMEI (parse be to [NUT]) http://forum.xda-developers.com/showthread.php?t=2593918
That should give you a clean stock sony .532 firmware ready to root. To root use Bin4ry's tool linked in LordManhatton's guide, then run through the steps in [NUT]'s .290 locked BL ROM thread and the his .136 locked BL thread. This has to be done in order if you are keeping a locked BL all the way through.

I am very thankful, for your guide and assistance. I am back on stock 532. Is it possible to flash another kernel/boot since this 532 sems to be without root and reovery. All tother things are back though. I cant find te thanks button. Where is that here on xda..?
Could i jjust write fastboot flash boot and then the actual boot.img? So that i can root it...
Recently picked it up, an SGP561. I have some questions and I'd love all of the help I can get.
1. How to install a custom ROM on it (just in case). If I can't get the updated Sony firmware, I might as well jump to an Android 5 ROM once they're stable.
2. How to update the stock firmware. Everytime I go to the System Update thing it says there was an "Error during DM Session"? I'd really like to update to 4.4.4 stock to get some of those nifty Sony features.
3. Anyway to get the damn thing to shut up when I turn it on? I'm not using it on a data network, just WiFi, but I like having the option, but everytime I start the damn thing up (from being completely off) it makes a calling new and does through this automated annoying thing asking me about purchasing a calling pin, and it does that for about 7 minutes and makes me about go insane.
Anyway, thanks guys. Boxes of donuts to all of those who answer.
(Already rooted the thing)
Hi Grayson,
1. Currently, there is no way to unlock the SGP561's bootloader. So basicly, you can't install any custom rom that is not based on stock rom (or use custom kernel).
2. Mine gets the same error. But you can download the latest ftf file for SGP561 and flash it manually using flashtool (sadly, the latest version is still at 4.4.2).
3. I face the similar situation, the tablet automatically dial some number to activate it when it boots up. All I did was just simply removing the Verizon SIM card (I don't use data anyway).
1. Well ****. That's actually very concerning... This tablet probably won't ever see Android 5.0 then... unless some genius out there cracks this bootloader deal. I know how Verizon is with things.. or I'll see an outdated version of Android a year after all other variants get it. Are there any ROM options?
2. How do you go about doing that? Pardon the noobishness.
3. Thanks! I didn't even know that there was a SIM card in there in the first place. That was a great help. Same here though.

1. Yeah, I know how that feels. You bought one of the top high-end tablet and then figured out that it has the outdated software and there is no way to update. I've been looking for other solutions for months but still found nothing.
2. The latest version is now 17.1.D.0.437. You can check in your tablet settings to know whether yours is on the latest or not. If it's not the following links may help.
Here is the instruction how to use flashtool (just in case you have no idea about it): http://forum.xda-developers.com/showthread.php?t=2054486
And here is the link for the latest ftf file for SGP561: https://mega.co.nz/#!VZYHRAKT!wky8U_6G9aB4XctdfKMIaJQZtdlnWTtNv0pNLlgh0AM (I got from this thread http://forum.xda-developers.com/xperia-z2-tablet/help/flashed-wrong-boot-bricked-t2839828)
Well this all sucks a lot. Why can't they just leave the bootloader unlocked... hopefully this tablet wasn't just a massive waste of money.

I got mine two days ago, also have the Galaxy Note Pro 12.2, which I use at the office, but I needed something that had a smaller screen, was light, and had 4G, and the Sony ticked the right boxes. I WISH I could use Xposed but it can't write to /System. I have it rooted and got rid of some bloat, and the only thing I really want now is for Xposed to work.
You guys don't think Verizon will update this tablet to Lollipop?
Hi I just updated my tablet to lollipop and I'm having problems with it. I tried downloading the ftf for kitkat above but he kinks we're dead. Do you still have it by chance?
Still no options to unlock the Verizon's SGP561 ?
I'm in the UK and we have a place call Cash Converters, it's known for selling second hand goods.
I bought myself a Sony Xperia Z2 Tablet LTE 16gb in mint condition with all the accsessories and box.
I paid just under £150.
I was running Lollipop but for me personally the device was slow. I downgraded to KitKat and it's great, fast as hell. really impressed!
I'm not rooted and I'm on the latest KitKat before the Lollipop update.
I removed all the bloatware 1 by 1 and removed the Google apps I wasn't going to use.
I'll tell you now, it's reallly fast.
well to my question; Because I'm on the latest KitKat before Lollipop - is there a way I can root my device?
PS: I don't want to spam the forum so I'll ask here - what sort of battery life are XDA Members getting with their Z2 Tablet?
Lollipop is faster than Kitkat on this device.
Must have been something else than the firmware which slowed your device down.

Well, it depends on the version of KK. If it's 4.4.2 the root process is definitely easy by running the easy root (towel root) program. After that, the towel root author got hired by Sony, so, so much for getting any simple root processes.
As with 4.4.4, you can get root, but you'll need either to use;
a) Bootloader unlocked, and a modified Boot Image Ramdisk to get full System RW
b) Install Nutz dual recovery (easier with bootloader unlocked)
With LolliPop, I already had bootloader unlocked, so I installed the latest Dual Recovery by Nutz, and installed the latest pre-rooted LolliPop build.
One note on unlocking your bootloader if you decide to go that method. Back up your DRM keys first. Then if you ever decide to go back to stock, you can reflash them. Note it only works initially with 4.4.2 Builds if I'm not mistaken. To be honest, I have them backed up, but don't really notice them missing. Supposed t maybe do something with camera or video enhancements, but I can't tell the difference.
As with speed and battery, I can't tell the difference between the 2 versions. Benchmarks are about the same. Battery life is subjective depending on how you use the tab.

You can unlock your bootloader with any version. In the forums there is an app called Flashtool if I'm not mistaken that you can use to relock the bootloader.
Read this;
http://forum.xda-developers.com/showthread.php?t=2747676
Be aware it'll wipe your /Data partition so you'll need to re-install your downloaded apps. Maybe docs and photos as well.

Aha. Similar to mine. I wound up getting a Demo model (unknowingly). Had the same "no" for bootloader. I wound up flashing a different "Ftf" file using Flashtool. Put a different region Rom on it. Workedfor a couple of folks, unless you have one of the carrier brands like Verizon, ATT, Tesla, etc.
So try flashing a 4.4.2 FTF file from a different region. See if it installs an unlockable bootloader. It's worth shot.

Having issues copying the link, but go to the regular z2 forum, then the cross development forum. There is a thread for "xperiafirm". This is a Pc app that will download almost every version Ftf file for Sony devices. Find your device (511, 521, etc) and download a couple different region Ftf files.
Flash using Flashtool that I sent you a link to.

OK, so here's the scoop.
1. Don't flash any files from our forums (zip) files. They are for custom recoveries.
2. Use the experiafirm software to download specific ftf files for your device. I'm mobile now and can't paste a link. You can find the Pc app by going to the Z2 phone forum, then go to Sony cross development. There you find the ExperiaFirm Pc app. Install it to a Windows Pc (instructions are in the post). Select your device on the left (Z2 Tablet), select specific model, and you should get all available factory firmwares on the right.
3. Select a firmware to download to Pc. Pay attention to the carrier versions. You probably don't want these. By carrier, I mean phone companies like Orange, Tesla, Version, etc. These are devices that are sold by the phone providers and usually you can't unlock the bootloader.
You want just normal Ftf files, like Vk, Ru, Baltic, etc. Should be about 30 or so available for your device.

thanks for all your help but I've gave up.
the link you told me about, xperiafirm, I couldn't get the ftf files. NO matter what I done.
I messed my Z2 LTE Tablet up and it was in a boot loop.
I fixed it with PC Companion and left it at that.
I have a Sony Xperia M2 too that I couldn't unlock it's bootloader, I kept getting "failed - command not succeed" so I just give up.
I have literally done everything and I still can't do it.
all I want is to calibrate my battery on my Z2 LTE Tablet & Sony Xperia M2.
is there something else I can try?
I'm running stock on both of them (latest in the UK through Sony's PC Companion) and I've disabled all the crap Sony apps and Google apps.
they're both fast now.
ugh.

You have to bundle the files downloaded from XperiaFirm, into an FTF, you do this with Flashtool:

Hello. I just received an Xperia Z3 Compact tablet (SGP641) compact tablet that I bought used. It is unlocked. I don't know if that means it is rooted, as well, as I am new to this.
Anyhow, I tried to update the tablet through the device itself, but it says it is up to date at version 5.0. So, then I try to update it using the Xperia companion on my PC. When I try, it gives me an error message that reads: "Update failed. The device contains modified software that cannot be updated. Error code: UEGetPhoneInfoRootedDevice
UE_2003"
I have no idea what this means. Does this mean that I cannot update the tablet, at all? Can I "un-root" the tablet? Basically, what are my options at this point? I would just like to update to its latest Android version. The battery life is not what I was expecting. I mean, it drains over 20% in an hour. Is that normal? I am hoping an update might help this out a bit.
Thank you in advance for any and all help, advice and suggestions. I really don't know anything about this, so I really would appreciate all the help I can get.
Thanks!
Edit:
So, it turns out that the device has been rooted and the bootloader unlocked. The seller just conveniently forgot to mentioned this during the sales process. Very frustrating. What can I do?
No the battery drain is not normal. I did not get an update either, here in The Netherlands. So I flashed a stock German version instead and changed the language afterwards. You would need Flashtool for that. The Xperia Blog has a good tutorial for Flashtool, but I guess you can also find it on xda. If you flash a stock version you will be unrooted as well.
If you wish, you can also lock the bootloader again in Flashtool.
Since your bootloader had been unlocked your DRM keys are probably lost, resulting in lower quality photos at low light conditions.

Thank you very much for your reply!
I am concerned to read that about the battery. I am beginning to really feel that I go a lemon.
Could you possibly explain more about flashing to stock, please? I am going to search and check out what you recommended, I just thought in the mean time you (or some other helpful poster) could clue me in a bit more.
Do you know if I can use the Xperia companion tool to do a software repair? It is an option within the program. I am just wondering if that will re-lock it and allow me to update.
Thank you very much, again, for your help! I really appreciate it.
I am not sure if Xperia Companion still works with an unlocked bootloader. But you can always give it a try. Flashtool is a much more powerful tool as it allows you to choose the rom you prefer, even if it is a downgrade.

Do you if there is any way to tell what, if anything, is on the device...as far as custom ROMs, rooted, unlocked boot loader...etc?
In Settings -> About you can access diagnostics with some basic info. More advanced diagnostics can be accessed if you install a phone dialer (I tried Pixelphone Dialer) and dial *#*#service#*#*. In Service Tests -> Security you can find your bootloader status. If it is locked it says Marlin [Key OK][Active] and the same for the other items. In addition you can find lots of other info there.

Will I mess anything up if I go ahead and flash a stock version or try to relock it if, by chance, it is not locked, rooted or anything?
Nope, but make sure you flash a correct ftf for your model. I'd advise you to wipe data, cache and apps log in Flashtool to make sure you have a fresh start. Any Marshmallow stock rom would be ok.

I am having a rough time finding out what to do. The only thing that I can see is the Taiwanese version, which is the model the SGP641 is, but I am confused about how to do it. Can I just flash it to the file that is on Xperia blog, or do I have to downgrade it first?

Well, as the Dutch philosopher Johan Cruyff said: every disadvantage has its advantage. It depends on what you want. If you want to stay rooted, you can flash a prerooted Marshmallow rom for your model from recovery. Usually you can enter recovery by pressing volume down or up during boot until the led changes color. Root is attractive because you can remove bloatware and install costumizations. If you do not want root you can flash a stock rom with Flashtool.
dude you want only to update marshmallow?if not,i can give u 2 options for a veeery stable and battery friendly tablet.
