ME572c - downgrade from Lollipop to Kitkat - MeMO Pad 7 Q&A, Help & Troubleshooting

What is the easiest way to downgrade this from Lollipop to Kitkat? The instructions that others have posted on here are obtuse and buried within dozens of pages of unrelated topics. Can someone help? please?

HELLO??????
I tried running Downgrade.cmd. Following all the instructions. And now my tablet it bricked. IT won't go based the ASUS logo and powered by android ident?
My computer recognizes it still, as a generic Android device, and says it cannot start.
Any help? ANY AT ALL?? PLEASE???

[Q] New to tablets and ROM

Hello ya'll, I'm new to the forum, I joined because of the wealth of information here.
So I'm not new to Android, had one ever since I was 16. I rooted both my droid phones(droid X with that awesome slider keyboard, and RAZR MAXX) to remove those pesky bloatware apps, but didn't ROM them, as it just wasn't something I wasn't aware of when I did it. So rooting was as far as I got.
But rooting and ROM-ing a tablet seems like it could be a daunting job, I'm new to the tablet world But I already have most of the tools, from previous roots, minus a few that are platform specific that I'm currently downloading to support the new CROMBi-X
I figure I'll go about getting everything I need, so when I get my tablet back from the shop, I'll be able to dive right into the CROMBi ROM.
//
I don't want to brick my tablet so hence the questions I am unclear on.
//
Question 1: Asus doesn't have the standalone unlock tool on their website. How do I go about getting that tool to unlock the tablet? Was it done OTA or downloaded and installed onto the tablet?
I have searched a few places, and browsed the developer forums, but haven't come up with a surefire way yet. I've seen everything from asking ASUS to unlock the tablet, to flashing CWM recovery, and than flashing a rooted version of the stock ROM, 've read several of the forums, but I need a little bit of "English" on the topic, as this is something new to me. I did come across a root.zip link but I'm not entirely sure that is what I am looking for, or if it is version/BLoader specific. If it is, then that pretty much covers that question.
Question 2: Are all the drivers on the ROM? Or do I need to use something like [ADB/FB/APX Driver] Universal Naked Driver 0.7?
Question 3: Mods. Are they downloaded OTA from the play store, or is there a list of compatible mods for the ROM? I realize that most of them are probably cosmetic right? I'm probably asking in the wrong forum, but since this is LINUX based, once rooted, if I put Ubuntu on the tablet, and then run a ROM on top of it? or Do I have to choose between one or the other?
I'm only asking because I run a few programs that aren't able to run on the android platform that I use for recreational purposes.
Anyway, that about covers a few of the base questions I have for now. Time to get ready for work. Thanks for any help in advance!
For 1:
It's on ASUS website
www.service.asus.com/#!downloads/c1wax
Version V1.0
Unlock Device App: Unlock boot loader of TF701T.(Only works with 4.2 JB and later OS)
For 2:
It's been a while since I rooted however I think you only need fastboot to be able to put the custom recovery on the tablet. If you have ADB/FB drivers already installed your pc should see your tablet without an issue. I don't know what APX is.
For 3:
Not sure what you mean by Mods. And last I checked I don't think that you can and Linux to this tablet yet however even if you could you only get one or the other.
Oh and make sure you read through all of the instructions for rooting and roming

sleepy2 gave you the link. You find the Unlock Tool under "Utilites" on the TF701 downloads page

First you need to determine what firmware you are running now and decide which JB version you want to run.
Check under Settings > About Tablet > Software version. On stock your firmware version and bootloader version are identical.
If you are on JB 4.3 you have either 10.26.1.7 or 10.26.1.18 (if you have the former, update to .18)
If you are on JB 4.4.2 you have 11.4.1.17
On JB 4.3
a) You can root the tablet without unlocking the bootloader with Towelroot v1.
b) You can unlock, flash CWM and then flash sbdag's stock rooted rom, one of several custom roms or just the root.zip
On JB 4.4.2
Right now there is no way to root without unlocking the bootloader and flashing a custom recovery first.
Once unlocked and with CWM installed, you can flash sbdag's rooted stock rom or flash the root.zip.
CROMi-X 7.0 for 4.4.2 is in the works. I do not know if the other custom roms (CM, CROMi-X 6, CROMbi-KK) are compatible with the 11.4.1.17 bootloader yet, but that's just a matter of time.
To install CWM follow the insructions here:

Try it. I did not have to install new adb/fastboot drivers and the device drivers installed on my PC automativcally. YMMV
Open Device Manager, then connect the tablet. Let the drivers install and see if it shows up in Device Manager.
Then boot the tablet into fastboot, connect it to PC and see if it shows up as a fastboot device.
Enable USB debugging in Developer Options, then connect the tablet booted into Android and see if it shows up as ADB interface in Device Manager.
If you need drivers you can use the ones you mentioned.
Question 3: Mods. Are they downloaded OTA from the play store, or is there a list of compatible mods for the ROM? I realize that most of them are probably cosmetic right?

You'll find mods in the rom thread or at least the links for those that work with that rom.. No OTA updates
I'm probably asking in the wrong forum, but since this is LINUX based, once rooted, if I put Ubuntu on the tablet, and then run a ROM on top of it? or Do I have to choose between one or the other?

There's a thread in the TF700 dev section on dual booting Android and Ubuntu. Not aware that anybody has tried it on the TF701.
Thanks for the link Sleepy! I had searched the website a couple times before, but I must have missed that part of it. Every other time I went somewhere to find it, it came back page unavailable. I'm really disliking this Kuwaiti right now! Well I won't know until I get the tablet back what JB is on it, but I imagine it would be sent back to a factory setting because of the issues I was having, or just get a whole new tablet all together depending on what was causing it not to charge.
I appreciate the clarification on everything guys, without the tablet in my hands I'm pretty much downloading everything I can that might help me out. I already have CWM, and several versions of it to be on the safe side.
I have been doing nothing but non-stop research, but it's daunting to try and go through 115 pages of information and tools, and version changes and what's compatible and how to use them. Watching videos has simplified it a little bit.
The reason I asked about Ubuntu, was I saw it dual booted to an older CROMi 2.X on the 700T
I used to run XP pro/Ubuntu on my laptop. Which was really nice when I needed a lightweight OS to free up processing power. Well before I had to format due to a near catastrophic drive failure and unrepairable data corruption. Anyway, that is a project for another time, one thing at a time!
I'll be around, busy with work 6 days a week!
Thanks again!

4.4.x is KitKat, not Jelly Bean, isn't it?

Yes.
List of repairs done
So what I thought was a simple battery not charging issue turned out to be a host of things. I had to have the LCD, Touchpadboard, Docking cable and LCD cable replaced, luckily I was under warranty. I imagine that would have been expensive!

[Q] Hard Brick? Flashed stock and OTAed

So I didn't read any guides and was following an old YouTube video on how to go back to stock and OTA. Unfortunately the link was for an older version of the Moto X Toolkit and it took me back to 4.2.2 and I accepted the OTA. gg.
I have tried flashing 4.4.4, 4.4.2, 4.2.2 again from fastboot and in the end the result is the same: a flashing dead android popping up every few seconds that says error. After reading the Q/A I think this is a hard brick but has there been any updates on ways to fix this?
I can't USB mount to put in a custom rom either and it won't let me sideload since the USB mounting isn't working. I can flash custom recoveries but that's about it.
Thanks.
Not researching first on any device is a mistake for sure... Especially the X. You've done the procedure that guarantees bricking a Moto X unfortunately.
This thread may be your only hope now...

Good luck!
I looked into this method but couldn't get it to work since it wasn't recognizing the phone when I plugged it in. I did manage to unbrick it somehow by flashing a 4.2.2 version again using the toolkit (post camera I believe). I managed to boot up again in 4.2.2 but not really sure how to upgrade to 4.4.4 at this point without bricking again.
Is it safe to RSDlite to 4.4.4 using the right carrier?
edit:
nevermind... I turned the phone off to check the status of the bootloader and saw it was unlocked, did a normal power up. For some reason it said android is updating even though I didn't do any updates and it randomly turned off and now it's completely dead .

[Q] AT&T not letting me update to 4.4.4 led to several issues

The bums at AT&T gave me the 4.4.4 update and it wont let me download. The download always fails every time. I need to get to 4.4.4 from 4.4.2 (version 2.0 which AT&T released afterwards (not the stock)).
I attempted to downgrade my phone back to 4.4.2 (version 1.0) stock in which the phone started out on. I download it but when I try to use odin on it, Odin fails on the flash. Luckily, i phone didnt get bricked and I have a backup already. Just wondering if i can ever get to Lollipop 5.0 or stock 4.4.2 (which i can have a root with). Just asking what did i do wrong with the 4.4.2 flash? Also what are the steps to get 5.0 from 4.4.2 (version 2.0)?
Also, i need to stress this more, i am only a beginner and know little to nothing about this stuff so please explain as thoroughly as possible and sorry in advance if i don't know what a term or phrase is. Thanks.

Follow instructions in this thread first it'll get you to 4.4.2. Once there use towel root to root your phone. And install flash fire ( which will be found in the thread below)
http://forum.xda-developers.com/showthread.php?t=3077652
Then follow the directions in this thread to get to 5.0

Need download for stock 5.0 firmware

Hi Guys, call me stupid but I went and did something without researching it all the way, and now i have a major problem.
So, what I did was mistakenly try to install 4.4.4 on my 5.0 device, thinking I could then root and re-install 5.0. Odin gave me a pass, so I booted up my device only to find It wouldn't fully boot, and would then go to recovery boot. I then noticed the large "Do not attempt if on 5.0 already" warning. So what I think I need is the stock firmware for 5.0 lollipop for SM-G900A devices.
Any help relating to the topic, or someone saying I'm looking for the wrong thing, is greatly appreciated!
Thanks,

[REQUEST] We need to capture 5.1.1 update file

If anyone has a Fire tablet on 5.0.1 or has recently received one from Amazon but not yet powered it on and is willing to help out please do.
As mentioned in several other threads, when upgraded to 5.1.1 we lose custom recovery access. If you try to downgrade you get a brick.
What we need is, a 5.0.1 device that is rooted, sees the update, someone will to risk upgrading to 5.1.1 (should be able to stop it) and the ability grab the bin file from /sdcard/Android/data/com.amazon.device.software.ota/ once it downloads.
If someone is will to try this, post here before turning on a new tablet or trying the upgrade and we can provide step-by-step instructions.
I am currently asking amazon to send me the update so I can "manually update" it myself. Not sure if this has been tried. Will get back.
EDIT: I was told that I would be able to download it when it was released on the software updates page.
Not for the thread, this has been done now.
