Hi Guys, first of all thank you in advance for any answer you could give! it will be much appreciated!
Now, before anything I know there should be hundreds of posts about this issue but I was unable to find one that could apply to my scenario. But if you know any post that could be what I'm searching please just point me in the right direction :good:
Now, here is the problem:
We bought this cheap chinese tablet with andrioid 4.2.2 for my mother and it seemed to work pretty slow and some apps where not working correctly, there where a lot of adds even when she was not on an application, they just popped out on the main menu screen, and, when trying to register Instagram it displayed a message stating that there where too many users registered in the device. I tried to root the tablet because found that it could be because some temp files but it showed that it was already rooted... So my guess is that whoever installed the OS, did it with a "hacked" version of it.
Up to this point I have tried to do a hard reset but the issue is still going because it is still the hacked version of the OS, and I havent been able to find a way to completely wipe out the OS and install a fresh new version of Jelly bean 4.2.2
Can it be done with the device conected to a PC? or can it be done with a flashed memory card?
I know finding the firmware for a chinese tablet will be a major pain in the ass but, is there a version that could work for different models? (this is a Mobix MBX7 Plus, found the website mobix.com.ve but there is just no helpful info whatsoever)
Anyway, I hope you guys can help. Sorry for the somewhat long post
Again, thank you!!
Update!!!
I found info that could lead to the correct firmware, the CPU is an Allwinner Cortex A20, but Im still not sure if this format process is just like a PC, where you need drivers or everything is on the OS

After reading and reading and reading I am officially stuck hopefully someone or @stifilz can help. Hoping that i just missed something after reading too much info.
UK Sony Tablet S region changed when ICS came out for early update from US. Decided do JB update yesterday the flasher V3 got up to the end of data transfer part and tablet froze up and all coms went. left it for a while but nothing. After a hard switch off it hung at the sony logo. Got into recovery and did factory reset to try clear any issues or so i thought. Still hung at logo. Downloaded various ICS files and renamed to update.zip and tried to reflash. They all fail with the E: Prohibit error, occasionally error failed to mount system1.
I've attached my recovery log if anyone can help sort this il be a happy man.
TIA
After reading http://forum.xda-developers.com/showthread.php?t=2433323 I am starting to think a lot of these topics go unanswered and point to a flaw in the flasher, my region.prop is also missing and can only presume the tablet requires this for an update and the factory reset removes the root so cannot push another .prop over. So for all intents and purposes the tablet be fooked. I really do hope I am wrong but if i am right then why is this flashing tool still available after so many screw ups.
Well the screw up your are referring to is your own as if you had done your research you would know that trying to flash jb to the tablet s and not the xperia s will mess the tablet up as pointed out in numreouse posts and questions. so the reason people don't reply is that the questions have all ready been answered serveal times and the warings are there

I presumed I had done enough reading beforehand as the tool said Sony Tablet S so seemed the right tool for the job. I've flashed many things over the years and never screwed one up so this is bit of a shock to the system, My first reaction to your reply was to reply don't be smart then my second was to go check tool again, then third was ah f*#k. 26 letters in the alphabet and sony had to call the next model an S too. I cant say i keep up with tablet technology so thought they same thing pre flash,I didnt expect my tablet to be replaced in market so quickly after i bought one. Oh well lesson learnt now the question is wtf can be done if anything. If i send in for repair do they spot this instantly and try hammering me for a heavy bill to fix. Its under guarantee but they do say software issue they wont touch it.
I did read a lot about these problems but only reference i can find was today on page 36 of the flasher tool post. I blame mondays and my obvious lack of cognitive skills on them.

I read this article and made the same mistake:
androidadvices.com/sony-tablet-steps-update-latest-jellybean-firmware-click
I should have read the details better. I commented to the article that I bricked my device but it was apparently deleted...
The important thing I would appreciate knowing is if the tablet is completely unfixable. I just spent $150 on a new tablet but was hoping i could at least recover my tablet S and give it away.

Now thats why i thought it was ok i read that site first too rather than here. Too much reading after the event not before. So who are these idiots at androidadvices.com? The advice below is from that site and is what got me to reset tablet. Now i'm even more annoyed at this.
Note: Just in a rare case if the device doesn’t boot up or show the home screen then long press the power button to turn off and then re follow the instructions.

Naming the file update.zip does not help as we can not see what is fully going on. Anyway it fails due to a messed up vendor. This would make sense as JB files would mess them up. Then it switches partition and that also fails due to vendor, but a slightly different error.
Anyway installing 0042 should work as they do not rely on vendor files. This is HoneyComb 3.2.1R2 and it is ROOTABLE. From there you can use flasher again. See my signature for links

Hey thanks for getting back to me its appreciated. Tried all three files you sent link for. None worked it gives the prohibit/sku error. I've attached recovery files of each files attempt if you like to look at it. I've looked through a lot of your other posts and a few very similar ones as this and come to conclusion its damaged beyond repair and am tempted to use the warranty and chance my luck as its got few month left. Unlocked bootloader or the legendary files you have mentioned in another post would be useful but doubt we get to see either soon.
edit
Here's a shot in the dark...As tablet was originally a UK model and was changed for ICS is there any possibility that it has somehow defaulted back to UK and file signed-nbx03_003-ota-0042.001.zip would help. Its only thing i think ive not tried but cant find that version anywhere. Idea popped in head last week as there was a lot of reference to sku error being a region specific problem but then it went away until just now.

Sorry should have mention (but thought you would notice) they were the same file. Ok that is failing for the same reasons. Seems it is pretty messed up. You tried a factory reset yet? If not you may have some adb access on the boot logo???
Here comes a rant

I did notice but i eternal optimist and sorta hoped they different files even though filesize gave it away plus I already had that file from your links in sig but wouldnt be first time a company names files the same but different regions. Factory reset did numerous times now.
Didnt realise could get adb from logo screen so got hopes up again when lo and behold there in device manager was MTP device. After couple hours messing with it and getting lots of errors saying no driver etc I figured out putting hardware id in different adb usb driver inf files (USB\VID_054C&PID_05B3&REV_0100) would give me a working driver or so I thought. The PC decided after few minutes to give yellow exclamation and driver no longer works. Persevered with it until got driver stable but from command prompt adb says no devices in list.
Now all this happened early hours since 3am so not having greatest amount of patience (4hours not bad) i took a huff turned everything off and said [email protected]#k it ive had enough. This aint ever gonna work im resigned to this fact.
Now i may have not read one tiny part of the AIO tool which turned out to be biggest mistake i made in all this however for anyone else unfortunate to have a blonde moment would it not be possible to put some sort of checker in the tool to determine what is actually attached to be flashed based on hardware ID or something before any system changes occur. Having flashed many many devices from phones to consoles each and every one has a check of some sort before hand.
However putting that aside I think its disgraceful how Sony have treated this tablet and how locked down it actually is. This pains me but the £300 wouldve been better on a damn ipad.
@stifilz appreciate help you tried to give mate
Hi I am needing quite a bit of help and information, I know that the help and information I need is quite a fair bit to me, but to a lot of you might actually just be basic stuff, I must confess i am new to the rooting world, and android, But i have been Researching rooting my phone for a few months now and finally plucked up the courage to do it at the weekend, anyway first things first, i have a Acer liquid e2 v370 with jelly bean 4.2.2, kernel version 3.4.5, I rooted my phone with Impactor through my pc and, when it was downloading it stopped and a message appeared saying payloader stopped or stopped working, so i thought it never worked but i then tried it on my tablet and it rooted it, so i downloaded root checker onto my phone and it said i had root access which i was over the moon with, Did payloader stop because that's how it goes onto the phone and stopped because the download was finished? ok now this might seem a daft question, but i will ask anyway, ok ive done loads of research but come across all different answers and different preferred ways, so now i am rooted what do i do? what apps are a must have? do i have the correct things installed? the apps i have are " super su " Titanium Back up " Busy Box " T-W-R-P " Root uninstaller " Root Checker " and that's it, in one of the apps i cant remember what one exactly but it asked to turn off boot loader, but i read that rooting your phone does that, am i on the right path? i will also tell you the main reasons i wanted root access, i wanted to uninstall preloaded apps that i don't want or use i did try this with the root uninstaller but failed to delete the apps as there still on my phone, i also wanted my phone to run a bit quicker and longer battery life change themes, and make my music louderand get some game cheats and that's about it other than having the options to do what i wish with the phone, i am hoping to get a custom rom but i haven't backed anything up yet as all i have done is browsed through the apps and not changed anything, anyway i will apologise in advance if i have placed this thread in the wrong place, i did think it was more suitable to genral than any other place, i also would like to thank you in advance as this is a big ask, but now i have root i just need a point in the right direction to get me started, thanks again for your time barry[/I]
help needed

Hello Xda community,
Alright after exhausting all other options i have decided to turn to our community in hopes that i can come to some sort of resolution for this matter. Okay i own a Sophix Tab-840g past warranty my problem is my software was causing freeze and reboots i left it that way for a while because it wasn't bothering me. So i waited long enough for them to make a new firmware and i upgraded, however upon doing so i was not able to use the touchscreen. Also, i have no back up...... was a bad move in retrospect. I did some research and found that that the freezing was due to the actual firmware and many people had tried to update running into the same situation where the touchscreen stopped working.
The only difference between when i did it and when they did it is the company had there older firmware available still. That is no longer that case they only have the new firmware and after calling they no longer have old software available. Other people reverted back and atleast there tablet worked, however I CANNOT get the old firmware ANYWHERE........in there guide they talk of the use of update "update-tab840-v02-20130315.img" when using there batch program. The only firmware available is the new one “upgrade-tab840-v03-20130607" i'm looking for the older update "update-tab840-v02-20130315.img" to fix my tablet or a way to fix this touchscreen hard reset is out of the option i have already done this method a couple times, i tried installing from sd, and from the computer all with the same error. Thank you so much for reading this and also for any help i procure. I will be uploading the version of my firmware i have no and the old one if i get it so this can the fix for this dreaded problem with so few forums talking of a fix.
Thank you,
Captainsploof
P.S. having trouble uploading firmware at this point keeps saying page unavailable during upload 8/18/2014
edit: My mistake - After all my tablet is the ME181CX version, i was almost certain it was the C. Aparently this one can't be rooted yet.
Hello,
I recently bought this tablet, and started reading up on how to root it.
I have come across this rootzenphone apk, and aparently the latest 1.4.6.4r version should support this tablet. Nevertheless, i am having the problem of it just leaving the tablet in demo mode, and the rooting saying "failed". I have restored to factory settings, and tried to root again, to the same results.
Build number : WW-3.1.23.172 -> i recall reading something about only "ww-xxxx" models being supported, so i guess mine is one of those.
I am quite new to android, so i may not be giving some needed info :x
Anyway, any help would be awesome.
I am new here so please excuse me if this is the wrong place to post this, however I am in need of some assistance
I have a Samsung Galaxy TAB3 10.1 - GTP5210
I encountered the little android flat on his back, so I have downloaded a number of ROMS that were applicable to the device and used ODIN (different versions) to flash the device. ODIN says it has been successful and the device reboots only to be confronted with the Android flat on his back. I have even tried downloading the JellyBean and KitKat kernels, and used the odin .img to .md5 bat file converter; this also failed.
I appreciate that the tablet is old but it is my daughters and would really like to fix it. There are no option to do recovery etc, I use the power-home-volume down button to get into download mode and then locate the md5 and use odin to flash it;
I would be extremely grateful if someone could help me, as I am at a complete loss as to what to do.
Thank you all in anticipation of anyone replying
I don't think you're going to find a lot of help for a tablet released in 2013. I'd Google "dead Android" with whatever version of Android you're running and see what the Internet tells you.

Good evening, thank you for your response, I kind of searched for that on the internet that has how I came to be here; as "the internet" says use android with the correct ROM and kernel..
So was hoping that someone here would be able to assist, for example could I use a later ROM what kernel do I need?
I have no idea what version I am using as it does not tell me in "download" mode
Also do I flash the kernel first and then the rom or vice -versa
I am not even certain whether I have a partition or not? I am assuming I do given that when I install the ROM it appears to accept it and then just goes into continuous loop.
I appreciate that the tablet is 3 to 4 years old but I would have thought there would still be support out there for it.
Oh just one other thing, I bought a new battery for it and replaced that, just in case it was that.
thanks in anticipation of replies
