[Q] revert from CM10 back to newest stock firmware - Xperia Tablet Z Q&A, Help & Troubleshooting

I've been struggling with flashing Cyanogenmod on this device, but finally accomplished it with many hours of trial and error. I'm not a developer and with the limited support this early in the process, it's just harder than most Samsung devices, etc I have flashed. With all of this said, can anyone tell me what is the easiest way to revert back to the original "latest" Sony firmware for the 16gb US version of the Wi-Fi model? I get confused with the custom CWM Recovery I had to push to the device and I don't want to flash something and brick the device. I just want to be very clear so I don't make a mistake. Also, I did try the FLASH TOOL, EMMA, and my device just doesn't show up after following the directions verbatim. My device is unlocked and running the latest CM10 (4.2) and it just has some issues I am not pleased with...Seems a bit laggy in simple games, screen mirroring doesn't work, and the zoom issue in Chrome and other areas is a bit bothersome. Not complaining about the great work the developers have done, just thinking for what I do it may be best to revert back for now. It's just too early I suppose. Thanks in advance.

Does anyone know....

I'm just wondering, I purchased a phone on ebay (not knowing it was flashed/rooted). The boot animation says "clean rom" so after researching this site and the forums for this device, I see that it's probably a rom you guys are familiar with and it seems to be ICS based (from what I can see). With that being said, does this mean when they actually RELEASE the stock ICS that I probably won't get the update to my phone? Because I really would like to see what their stock version will be like. Can anyone answer that question or has it even been asked before?
you can't take the OTA rooted or while unlocked but you can flash the RUU once it gets posted after relocking your phone. hopefully by then we will have s-off.

So does this mean I will no longer be able to receive updates to my phone with this "s-off" or what ever? That sucks, and I can't seem to follow the steps that have been given to get it back to a stock rom or "ruu" what ever THAT means. lol ****that moment when you realize you might look dumb or "newbish" for posting what you just posted****
Your phone has been hacked a little bit, and it's always going to have tell-tale signs.
The worst case scenario is that you have to manually install the next official update and manually relock the phone, which will always say "Relocked" in the boot menu. But if you do everything by the book you should be able to get it back to stock in every other way, including taking subsequent updates over the air normally.
If they get s-off working and you're willing to experiment, it may be possible to completely revert the phone to stock. But that's quite a bit more hackage in order to get your phone "unhacked."

To be honest, the only thing I really want is to be able to get it stock on the basis of the apps, getting system updates etc. I'm not concerned with it having evidence of being "tampered with" "hacked" or "rooted". lol It already says "re-locked" The problem is the instructions I've gotten on here seem to go over my head. I might have to be walked through it like a little 3 or 4 year old being taught to sound out little words for the first time. lol Hey, I'm just saying..... No seriously though, I have a MAC and all of the instructions here seem to be based on having a PC
This can be done. But you're going to need to have somebody who knows what they're doing relock and reset your phone from the official ICS RUU after it's released, probably from a PC. There's nothing can be done before then.

So this means I'll need to basically need to take or send it to someone to get this done? I don't know why all of these instructions seem like their in spanish to me now, about 3 years ago I used to flash and unlock WM devices almost every other day. I guess I should've never stopped, but once the g1 came out and switched to android devices I stopped flashing and now I'm lost because I need to "tamper with" my phone again, but can't seem to get going at all. I mean SERIOUSLY, I used to flash WM devices so often that if a certain period of time went by without me finding a rom worth "flashing" I'd start having withdrawals. Now i'm feeling like an absolute IDIOT when it comes to getting into these android devices. I think part of that has to do with the fact that I only had PC's and now not only am I trying to tamper with android for my first time, but I only have mac computers as well.
Go to settings, about phone, software information, more, and write what your baseband version is.
http://forum.xda-developers.com/showthread.php?t=1417839
This thread may help you getting osx and fastboot going so you can relock and run an ruu. As was stated above, what is your baseband? If the previous owner flashed the leaked ics you will not be able to go all the way back to stock until either an official ics is released or the s-off tool is released. Good luck!

Unless you have issues, I would leave it as is for the time being. Take time to learn how to do all the stuff you need to do.
The custom ROMs really do make the phone better, you may find you want to keep it in the end. Battery life is much better on a good ROM.
When the official update comes out, we will have a new ROM based on the update within a day or two at most of the release anyway.
The baseband (the radio firmware) is also important. And unfortunately we can not downgrade to older basebands due to not having S=off. So if you are on the newest leaked version then you can run the old stock software.
BTW S=off (or S=on) is a security flag located in the firmware. S=on limits what parts of the phone you can flash and change. S=off gives you full access, it will allow you to downgrade as well. S=off also makes it easier to brick your phone because it does let you change software that is bootstrap essential, the baseband and hboot (sort of like BIOS) for example.
I separate the idea of bootstrap from boot. Most people associate booting with the OS, but bricking effects the firmware initializing the hardware that allows the OS to load and boot. So you get to see the old school term used.

The baseband is 1.22.10.0310r, 1.22.10.0308r It also says clean rom 4.1. I don't mind waiting until an offcial ics is released, but I will I be able to receive THAT instead having to have a "dev equivalent" version is what I'm wondering....
It's like I said. Those radios are new, and part of a firmware upgrade that can't be completely backed out. Your simplest bet is to wait for the official ICS release, and then you (or someone more technical) can apply it manually. After doing that and relocking your phone, it should start to take updates automatically again. You'll also have the full factory-installed "bloatware" suite of software.
It's possible to downgrade all the other parts of your software manually back to the latest stock release, but it's expected that your current upgraded firmware version will continue to prevent you from taking OTA releases. It would be good training, actually, though you'll get better results and more support from a PC than on a Mac. If you figured out how to do all this, then you could get your phone back on the HTC software track yourself.
Depending on your flexibility, maybe you can find someone here you could send your phone to who can put it back on the official release track. But even they won't be able to put a permanent fix on it until the official ICS release comes out and somebody uploads it as a manually-installable package.

EDIT:
So did the seller not mention on eBay that the phone had been customized?
Some of the responses lean toward telling you how to flash your phone for yourself. Is that something you'd have any interest in? Do you really want to go back to stock, or do you just want to see the difference?
Are you having any problems with the phone?
The custom ROMs are better, overall, but they usually have one or two bugs that you have to learn to live with. (Which is not to say that stock ROMS are bug-free, though the final versions of stock ROMs tend to be very, very stable.) But if you are on custom ROMs, then you're completely off the automatic update path, and everything will have to be done manually.
So unless you want to learn how to flash your own phone, the only way to get updates is to set it back to stock so HTC and Verizon can handle the updates for you. And therein lies the dilemma, because that in itself is something which must be flashed manually from where you're currently at.
(Oh, and you're probably going to end up losing any of your own customizations in the process, though the data on your SD card should be safe.)

Well, I've kind of decided to just keep what I have. I don't have any issues other and it seems to run smoothly. What I REALLY want to see is what the official update will be like as being "stock released" when it comes out and was concerned that I might not be able to get the update because of the "clean rom" I have now being ICS based (as far as I can see). Other than that, I'm fine until then.
You really should consider leaving negative feedback if they ebay seller did not state in the auction that the phone was rooted and running a custom rom. If I sell a phone and im too lazy to revert it to stock ill ALWAYS state its rooted and what its running in the auction etc

Good point, I mentioned it in the feeback portion and rated him low on the "item described accurately" portion
I would just wait til offiical ics is released. I am sure there will be instructions here on xda on how to relock and flash the new official ics ruu. It will involve downloading some files and entering items into command prompt from PC.

The problem is I don't HAVE a PC. It's already "re-locked" though. I just want to be able to receive the update without having to deal with any other flashing etc. But from what I was told, I should be able to since the current flashed rom is nearly stock (clean rom) and I'm already re-locked. But I guess we'll just see....

seems like people are giving you information that is kinda all over the place.
Lemme try and help clear this up, since you are in a odd scenario.
You are running cleanrom 4.1 on a re-locked phone. For starters, cleanrom 4.1 is based off the current ics LEAK and is not an official OTA update. Chances are high you won't be able to get the OTA if the rom is not a stock rom, and also because chances are you don't have a stock recovery even though it is relocked. Since you are currently on the latest leaked firmware, not an official firmware, you can run the RUU for the phone and go back to stock. In your case, your kinda lucky with this, as you don't technically need a computer to run it. You would need someone to extract the PH98IMG.zip file from the RUU.EXE file for you to run when the OTA comes out through Hboot.
Be for warned, doing it like this, will wipe all data.
I would say you should run the leaked RUU on the phone, as since it is a beta testing Leak, you should still get the OTA, and that way the phone will think it is completely stock and get the latest update.
If you wanna do this, ask and we can help you.

Yes, I'm VERY interested, I'm not worried much about the data wipe, between what's backed up to my google account and my SD card, I'll be fine with a data wipe. My battery life is also HORRIBLE for some reason with this rom, but since I've not had it stock yet, I guess I can't REALLY say it's good or bad. But my Droid Bionic's battery life was at least twice as good as this phone's seem to be and I don't use it any more than I did the Bionic.
I will tell you right now the battery life will most likely get worse if you go to stock.
Now if the person who sold it installed a custom kernel rather than the one Scott includes in his ROM (scott makes clean ROM) then battery life could be worse than it should be.
Second, this is a 4.3 inch HD screen... it eats battery like a starving animal.
Third, try cleanROM developers edition (a very striped out cleaned up stock based ROM) or cleanROM senseless. I am running cleanROM developers edition and I get double to triple the battery life over stock.
Unless I actually use the phone... When I use it a lot, I do not get that big of a jump. When using the phone the battery life will be similar due to the screen and CPU use remains similar to what stock would be. (which you would expect, the screen will always use the same power, same for CPU) Its when the phone is in standby mode that you see the real gains. Because all the extra junk that is in the stock software is pulled out and isn't constantly running in the background, waking the phone, starting the cell radio to phone home, etc.
Senseless and the Developers edition have their quirks caused by removing so much of the stock sense based apps and functions and replacing with AOSP versions. Thinks like the caller ID not showing up on the screen until you unlock the phone because the sense phone/dialer can not talk to the AOSP lockscreen. Nothing major just different.

[Q] Rom opinion/help?

My stats: Fairly comfortable with computer and other forms of tech, but have only recently began diving into the Android system. I have limited development/programming experience, however, I'm not a novice or noob to it but definitely not advanced. Importantly for those willing to help I understand most terminology and can follow instructions. Thanks in advance.
Phone Stats: AT&T Samsung Galaxy Note SGH-i717
Android Version: 2.3.6 (Gingerbread)
Baseband Version: i717UCLF6
Kernel Version: 2.6.35.11
Build number: GINGERBREAD.UCLA1
Root Access: Yes
Stock Rom: Unsure, bought online.
Carrier/Service Provider: Straight Talk (U.S.) Phone was previously used on the AT&T network exclusively, and done so with an AT&T provided SIM card. After I purchased it, I ordered a new SIM card from Straight Talk (U.S.) and reprogrammed the APN settings under their instruction in order for my phone service to work correctly, and have had no problems with that.
I can't stand being on Gingerbread any longer. I guess, since my phone is an AT&T phone but I'm using it through Straight Talk I can't get any of the OTA updates. I've tried downloading the OTA's several times, both, prior to and post Root access without success in either case.
So here are my questions:
1. Am I doing something incorrectly which might be keeping me from getting OTA updates? Please remember, I've tried downloading the OTA's several times both with and without Root Access and the conclusion is the same each time: "No Updates Available At This Time. Your Phone Appears To Be Up To Date. Try Again In 24hrs."
2. Is my only option at this point to manually update to a newer firmware? If so, should I update to a newer STOCK version or a custom ROM version?
3. If a manual update is the option, after reading my above outline of my own experience with the Android system, what would be way to go? Simple, not overly complex yet doesn't assume the user is either a complete moron or can write code in his sleep. I've checked into a couple of options. Rom Manager seems like it would be a nice route to go, but in the Recovery Setup portion I basically get told I can't use that application because my specific device isn't supported.
I checked out GooManager and, unless it's just me, it seems like it's an app that likes to do all the work without telling you what it's doing exactly, but when it does ask me or tell me information, I'm not always sure how to answer or react to it's warnings.
Plus, I've noticed that sometimes when downloading a ROM, sometimes I have to "flash" the gapps myself and other times I don't.
4. Is it easier to download everything separately and apply them one by one, for example the ROM then gapps then Kernal...etc? Or look for something that has it all in one package?
I have a laptop in which I can download/transfer programs and apps between it and my Note so download space and internet access isn't a problem.
Also, it most likely isn't information that is going to help in anyway, but I live in Oklahoma, United States of America.
Thanks for all the feedback...UnluckyOnion
I'm not answering these in any specific order,
As I kinda just sped read thru most of it...
Since you're rooted, or know how to, goomanager is superior to Rom manager.
It supports this device and has a current version of twrp to install, instead of an outdated cwm.
Just use it to install recovery, then boot your device into recovery and use that. Not the app. You'll be provided with much more information and this is the preferred way of flashing.
Official Updates are always "manual" either with a less than user friendly program called kies, or with a less annoying way (which you may be familiar with seeing as you've rooted) ODIN. Both pc programs used with the phone in download mode connected with usb cable.
Gapps are only needed to flash separately with an aosp based Rom as it's against Google's T.o.S. to include them in am entirely aftermarket compiled firmware, however if it's a Modified version of a stock based Rom (in this case TouchWiz) they can be, and thusly are, included within.
Official or custom is up to you really.
If official..just grab the .tar and flash it with Odin.
If custom, obtain a custom recovery either the way i mentioned above or downloading a .tar of twrp and use Odin to flash that.
Once you have a custom recovery, you'll simply be able to flash a Rom from there.
Roms include a kernel, if you want to use a different one than what is included, that would be flashed after the Rom.
After flashing you'll have to input your carriers apn settings in again.

Thanks for all the information and help...more importantly, thanks for taking the time. I have ODIN on my laptop and have always used it when needed but I saw a highly rated and positively commented Mobile version of ODIN in the Play Store that claims you can do everything from the convenience of your phone which sounds appealing, however it's kinda pricey, especially if it doesn't work. Would you recommend the mobile version or PC version? Also, I have been doing a lot of ROM and Root research as of late, and wondered something...Why so many different Galaxy Note's? It seems as though I have the least popular version with the most popular being from the Galaxy Note "N" series, specifically the N7000. If I download and use an application that says it's meant for the Galaxy Note N7000 and I use it on my Galaxy Note SGH-i717, what will happen? Nothing, something, brick, work perfectly, etc...?
The N series is not carrier branded and sold internationally, so naturally it's more popular compared to a north American variant.
DO NOT FLASH ANYTHING FOR THE N7000
IT WILL BRICK YOUR PHONE.
The international version has a different cpu, gpu and antenna, for north American LTE bands to work those key components needed to be different.
So I say again just to stress:
DO NOT FLASH ANYTHING FOR THE N7000
IT WILL BRICK YOUR PHONE.
As for Odin, you're either going to flashing a stock firmware, or if you choose a custom Rom, you'll only need Odin once to flash TWRP. Then all the rest will be done in recovery on the phone itself. No need for it after you've either manually updated to the latest stock rom, or flashed a recovery for use of custom roms
So... imo mobile Odin, though being nifty, is a bit pricey for how little you'll need it, whereas it's free on pc.
I don't think mobile Odin is even available for the i717. It's not listed in supported devices.
I tried installing mobile odin and it's not supported
Thanks for the reply. And an even bigger Thanks for downloading the app and checking. I admire sacrificing your own work just to help me out. So what about yourself? Would you suggest, advise or heed caution to anymore of my questions?
By the way, what are you two running?
As long as you read the op of threads and all other important posts that follow BEFORE ever touching your phone, I'd say try a custom Rom...if you decide you don't like any of them, you can Odin flash the stock jellybean firmware at any point.
I myself am running unofficial aokp compiled and posted by a fellow team member BlownFuze.
Oh yeah, how's it running? Nice and stable or crawling with bugs? Any key selling points?

I'm on the stock 4.1.2 release and rooted.
Everything works, no bugs, but battery sucks. Even after removing and freezing useless processes a stock rom will never be as light and battery friendly as a custom rom.
I just upgraded to the same version. Planned on rooting over weekend. Any success since your last post? Do you nave preferred Root method?

Use Odin to flash twrp
Newest version of twrp "should" Sr that you're not rooted and ask if you would like to do so within recovery before booting back into the os.
If not, there's links to an su.zip to flash in twrp for root.

Firmware question

I have a firmware question that I can't seem to find the answer to by searching. I ask running arhd 11 on an att HTC one. Should I upgrade the firmware on my phone? Will there be any benefits to this since I am on att and not international? Also how do I go about updating the firmware and does it wipe the device? Longtime Samsung user so please excuse the noobness.
I would hold off with updating firmware as there are issues with some ROM's and recoveries and the touchpad drivers in the latest firmware. A firmware install doesn't wipe the device.
I just updated mine to 2.24 last night. A few issues at first (mainly with TWRP and recoveries after flashing), but found a great guide that made it all easy.
I don't know if I'd do it again. Now that I'm finished, I don't have any issues at all but I suppose if its not broke don't fix it. I worried I bricked my phone last night when I did something wrong, but ultimately I figured it out with lots and lots of reading. I don't really notice anything different, but, if you're like me and have to have the latest and greatest, it can be a hard itch to scratch. You'd also want to upgrade to ARHD 12, since it would match the firmware version you're going to be upgrading to. IIRC 11 isn't based on the 2.24 fw.
If you want to do it, use vomer's guide here. Follow it to a T, including the TWRP download. You HAVE To download the TWRP from his link. The one from the official page loses touch with the new firmware (one of the issues that took me an hour to figure out). You'll also have to be S-Off, which is going to open a whole new can of potential issues, so be aware what that means and what you have to be careful of.
I did the same as @Eradik using the same methods. Like he said, follow them exactly (not hard to do) and use vomers twrp recovery (as the touch drivers are fixed in it).
The main difference I noticed was much better capacitive button response and when coupled with arhd 12 a very response experience. Other than that I'm not sure if there really are any noticsble benefits but it really isn't difficult to do at all and you don't lose anything with vomers method.

Good spec but lousy apps and Bluetooth.

I took a gamble buying a Chinese phone redmi-note 2 but sadly! it hasn't worked out for me.
All I wanted from it, was for it to do what it is supposed to do.
Bluetooth
Bluetooth doesn't connect to any of my devices, car, Hi-fi and not even my nexus 7!
Miui updater
Totally useless on my phone. This app crashes every time I select "choose update package"
I have looked for help on YouTube but the majority of videos seem to be Indian, using Indian versions of software where the updater app seems to work perfectly.
I managed to root my nexus 7 with ease but the redmi-note 2 is a nightmare.
I could really do with some of you android guru's to point me in the right direction! in finding a good beginners guide to finding all the apps and suitable rom for my phone, Or better still.! A way to get Bluetooth to work.
First of all check if your device has official rom or custom (if you bought it from China it probably has custom rom so flash official one).
Mine is working very good...
I second what ibeqa said - you're probably running a crapware-loaded ROM. Crashing updater is a good hint. You could also look into "about phone" section for the MIUI version, if it's something like 9.99.99 then it's crapware. "Legit" ROMs have version 7.xx.yy or 6.xx.yy. The crapware ROMs are IMHO the main reason why Xiaomi decided to lock the bootloader on RN3 and other newer phones. Because obviously, those ROMs give them bad reputation even though it's not their fault.
Bluetooth works fine for me, but sometimes it hangs up forcing me to restart it - not optimal but doesn't happen too often.
As for rooting, rooting the Nexus 7 (2012) was the same as RN2 for me - connect to PC in fastboot mode, flash recovery.img, reboot to recovery and flash a custom ROM. There are enough guides out there. For the RN2, fastboot can be accessed by starting the phone with the volume down key pressed.
Agree with the above. Please re-flash using official ROM via fastboot method and then try again. See http://en.miui.com/a-234.html
Android version 5.02 LRX22G
MIUI Version 66.77.33.00(LHMCNCH) Stable
Cpu octo core 2.2Ghz
Ram 2GB
I Have downloaded Update supersu 2.4 and miui HMNote2Global v7.2.2.0LHMMIDA_DA_d71ff21b81_5.0.zip are these correct please?
I installed CWM but have read that TWRP is the one I should be using! is that correct?
The trouble with the redmi 2 ,is there is too much conflicting information out there, making it very difficult for a newbie.
Is there any other things that I need to download?
This whole thing has really put me off the Xiaomi brand. I just expected bluetooth to work ! it is supposed to be standardised worldwide.
To you Guys it is probably fun to mess about with different roms, all I wanted was a working phone.
"MIUI Version 66.77.33.00" <- that's your problem right there. You reseller installed a crapware loaded ROM and has modified the version so that you never get an update (= he can spy on you forever), had you bought from another one, you would have gotten a working phone. I know mine did.
Putting blame on Xiaomi for this is misplaced, unless you want to blame them for being dev-friendly and leaving the bootloader unlocked. They reconsidered by now, though, their newer phones are locked.
In any case, yes TWRP is the way to go personally. CWM has cut important features like backup/restore (at least the version shipped with cyanogen roms I tried), so it's basically useless.
For the ROM, if you have downloaded it from the xiaomi page, then yes. You could also get the rom from xiaomi.eu if you want to use an European language.
If you just want official MIUI then you don't need to install custom recovery (use fastboot method instead as per official instructions). In fact the custom recovery will get removed next time you receive an OTA update.
Personally I use TWRP from this link http://en.miui.com/thread-224679-1-1.html because I wanted to install root. But only do this AFTER you install a clean ROM at the first place.

I bought the phone from Gearbest.EU and expected it to be direct from Xiaomi, as I have never had a problem with this company before.
I have had another go at installing a new rom with the Mi suite and also with the miui flash tool and am not getting anywhere with it. I can't even root the damned thing as it boots into Mi when pressing vol up and start. This happened with CWM and TWRP.
I have said before,that I have little experience with android and perhaps I am going wrong somewhere! or the tutorial posters are using phones that have totally different roms to mine. ,It is very difficult when you have Indian,Chinese and global versions with many variations of each, the same seems to apply to CWM and TWRP.
Is there a way to install this via windows, ie formatting the phone and running an installer direct from pc?
I had a dabble with Linux mint and Artist in the past and found them quite user friendly, I can't believe that android is Linux based! I could have done a fresh install of windows, several times by now,the amount of time I have spent on this. Of course windows truly is global with only a couple of variations . Format disk, run and your away. Then hours installing software.
I am fast getting to the stage where I shall give it a bounce test, from a great height. :crying:

Sony Z2 Horrid Device

The Sony Xperia Z2 tablet has got to be the most horrible device in android history to root or install a recovery on it. The process and the complexity of it is just horrible. You daren't ever make the slightest change to a rom or anything in twrp as it just screws everything up on this device. I can't count the amount of roms i've put on it just to totally trash the device and you have to start from scratch. Either you put a new rom on, it wipes the recovery, you have to piss about using flashtool to flash some other ftf on just to get into recovery, then you have to then flash another tft to get root, the list just goes on and on. I don't even know why sony mobile even bother offering the bootloader unlock option in the first place, it's an absolute nightmare. It's basically you can have root with the official stock firmware, if you want a custom rom spend the next 2 weeks trying to get supersu installed on it. The most horrible device I've ever come across.
Then sell it :laugh:
Somehow I cannot share this view. Running Carbon ROM with Magisk without any issues. For a more than 4 years old tablet the Z2 stands its ground, I don't regret having bought it.
Just hoping that we'll get Pie...

I've tried Carbon and would love to use it but it just screws up the tablet after install and recovery gets wiped so you can't even go back to restore a back up. You then have to reflash using Emma then back into flashtool to reflash the tft to get recovery to work again because flashtool ends up reporting back that the current tft is not compatible with the device. It's a finicky device to root. It's got to be the worst out of all android devices. E.g my Samsung s9 had it rooted and flashed with a custom rom in around 5 mins. No matter what firmware is installed. Sony decided that after 23.1.A.575 or whatever rooting was not possible after that. Also every method on here telling you how to do it is different to each other and inconsistant. I tried 23.1.A.575 root for UK and it would not allow for twrp to be booted into. I had to use xperiafirm to download the Taiwanese version so I could get the batch script to allow recovery so holding down power on volume down would allow twrp to load. It's just a painstakingly horrible device to root to get something so simple. But yes your right probably best time to get rid and something different. Sorry for the rant it's just been a frustration for me.
Sorry to say so, but rcstar has a very good step by step description on how to install the ROM. I followed it to the point and have no issues whatsoever.
TWRP, Magisk and Substratum work, like everything else.
It's not a device which is easy to mess with, you are right. But it's doable.

I've followed so many without much success. I tried the solution by kulvertti to the letter and the tab was having non of it. I think the problem also is that a lot of the links are dead to the specific tft you need to download so getting the exact version is tricky. The only one that has worked for me is the Taiwanese rom then using the recovery script by danalec to get Marshmallow flashed which is what I'm running now. So I made a back up today and thought OK let me try carbon because I can get all the nice customization options like being able to choose a dark theme for the settings menu instead of piercing white. What is it with manufacturers wanna make every thing bright and painful on the eyes. Anyway downloaded gaps wiped system etc installed rom and once it loaded the system was all unstable and lost root and recovery. So I give up now and have to accept I can only have marshmallow on it.
Danalec has a very simple root method for Marshmallow in the general section. This is one of the best tablets out there by far. Build quality doesn't come close with other brands.
