Thank you! I now have it installed. Build number shows as 12.14.1.17, and I can confirm it has root. You rock!!

One thing I want to point out, though. Since I'm on Windows 10, I had an issue running the batch files. I think the problem was that it was default opening them in PowerShell instead of Command Prompt. So I had to open Command Prompt as administrator, browse to the directory of the batch files, and run them through CM. It then opened them in PowerShell again, but it didn't have any issues after that.

Help!!!

Help!!! I follow that intructions and now i have intel logo stuck, I tray run Downgrade-2.cmd but it doesn´t work and say "FWR_DnX not exist".

Downgrade.cmd say "waiting for device".

What i can do??:crying:
[MeMO Pad 7 Q&A, Help & Troubleshooting] pWEN:
Once you do the initial downgrade to KitKat and then upgrade to the pre-rooted Lollipop, you shouldn't have to downgrade to KitKat again. I didn't have to this past time.

What operating system are you on? Is it 64 or 32 bit? What steps did you follow? What files did you download, and from where? If you're on Windows 10, did you try the trick I mentioned of going through the Command Prompt as administrator to run the CMD files?

[MeMO Pad 7 Q&A, Help & Troubleshooting] pWEN:
Are you using the old files with the new firmware? If so, don't. Grab what xda-log links to in his instructions (after the quote where he edited my instructions). Also, you will need to follow this process before installing the drivers since you're in Windows 8.1.
[MeMO Pad 7 Q&A, Help & Troubleshooting] quechua1:

Edit: I made that changes, now downgrade.cmd say "¡¡¡Error!!! FWR_DnX DONT EXIST, EXIT!"
[MeMO Pad 7 Q&A, Help & Troubleshooting] pWEN:
Try right-clcking the downgrade.cmd and running it as Administrator. You can also open that file in Notepad to see where it's looking for that file and make sure it's there. Otherwise, I'm not sure what else you can try. Maybe [MENTION=3531407]xda-log[/MENTION] will have some ideas.
[MeMO Pad 7 Q&A, Help & Troubleshooting] quechua1:
I try running it as Administrator and the downgrade.cmd say: "¡¡¡Error!!! FWR_DnX DONT EXIST, EXIT!".

[MENTION=3531407]xda-log[/MENTION] is someway to take out the Intel logo stuck as you made with the old files with the Downgrade-2.cmd?. If you can´t help me my tablet is brick forever :crying:.
[MeMO Pad 7 Q&A, Help & Troubleshooting] pWEN:
Okay, I just checked something, and the new files do NOT have downgrade-2.cmd as it's NOT necessary anymore. I looked through the old posts, too, and remembered that I had encountered issues like this before.

Before going any further, I need to know:

Are you trying to downgrade to KitKat?

Were you already on a pre-rooted firmware?

Was it a KitKat or Lollipop firmware?

Did you install the ADB drivers?

Were you able to successfully install the Intel drivers (from the IntelDnXUSBDriverSetup.exe file)?
[MeMO Pad 7 Q&A, Help & Troubleshooting] quechua1:
1)I was tring flash new lollipop firmware but i couldn't get access to recovery mode, it stuck in intel logo.

2-3)It had pre-roted lollipop but i restore factory setting to official .12 lollipop firmware for flash the new lollipop firmware.

4)Yes.

5)Yes.
[MeMO Pad 7 Q&A, Help & Troubleshooting] pWEN:
If you put any official firmware (something from Asus) on your tablet, you HAVE to downgrade to KitKat and follow xda-log's instructions (that I linked above) to install a pre-rooted Lollipop. That is, if you're on a NON-ROOTED Lollipop firmware, you MUST downgrade to KitKat before being able to put a PRE-ROOTED Lollipop firmware on your tablet.

If you're still getting the Moorefield device issue in Device Manager, you may need to uninstall the drivers and try again while in the advanced reboot with driver signing turned off.
[MeMO Pad 7 Q&A, Help & Troubleshooting] quechua1:
I make it work!. After read a lot about zenphone. I turn off the tablet and i connect it holding vol "+" and "-" then i run downgrade2.cmd and it get recovery mode :D

It wasn´t necesary go back to kitkat i flash pre-rooted Lollipop .17 above official lollipop .12

So wich is the RIGHT procedure to upgrade withou loosing data (wipe) fro 12 ROOTED to 17 ROOTED ?

Little of confusion...
[MeMO Pad 7 Q&A, Help & Troubleshooting] xda-log:
You must delete line fastboot erase data from Downgrade.cmd (and Downgrade-2.cmd too if you use it).
[MeMO Pad 7 Q&A, Help & Troubleshooting] therealprof:
Indeed. Actually after going through the horrors of the whole procedure gone wrong (and recovering from it) I've no idea the why the ones who came up with the approach are doing it so astonishingly complicated and non straight forward...

There is no reason to downgrade at all if you "just" want to root your current software. The approach basically uses a documented procedure to sideload your own software (and in this case actually only the early stage and late stage bootloader rather than the complete flash) on Intel Atom SoCs. In a nutshell it downgrades the Atom "Integrated Firmware" ifwi to version 77.43 (not even sure this is necessary at all) and bootstraps a custom droidboot bootloader which accepts a flashing of the unsigned modified image with the root access built-in.

Everything else that is mentioned in the howto is complete nonsense and counterproductive (like downgrading the system to Kitkat, involving a repartitioning of the flash and thus the loss of all data which is even very risky in case of devices with built-in modem). Also due to the Kitkat downgrade the scripts contain far to much "magic" to revert back to the older version including the removal of all user data and configuration. Coming to think of it it might not even be necessary to flash the full system; an unsigned update image that contains the su utility should actually be sufficient.
[MeMO Pad 7 Q&A, Help & Troubleshooting] karletto66:
I agree.

I looked at the script and my (small) hopinion just to change from .12 to .17 lot of thing are "unclear"

So better to wait a shorter and sure (well...almost) procedure...
[MeMO Pad 7 Q&A, Help & Troubleshooting] quechua1:
UPDATE FROM LOLLIPOP .12 (OFFICIAL OR PRE-ROOTED) TO .17 PRE-ROOTED LOLLIPOP WITHOUT ERASE DATA INSTRUCTIONS

1) Download the firmware for your version tablet PRE-ROOTED .17 LOLIPOP firmware for K007 (only Wifi) or PRE-ROOTED .17 LOLIPOP for K00R (Wifi + Lte) , and the fIles needed (this files are new and modified for don't erase data).

2) Rename the .17 LOLIPOP firmware to MOFD_SDUPDATE.zip (make sure the "zip" is lowercase) and put it on your tablet's EXTERNAL SD card.

3) Extract the "Update to .17 Pre-Rooted.rar" file and run the IntelDnXUSBDriverSetup.exe file to install the drivers. Install ADB drivers if it is not installed yet.

4) Turn off, then turn on your tablet by pressing volume "+" and power button, it boot your tablet into the fastboot mode, and connect it to the computer.

5) Make sure what tablet defined on the PC device manager as asus android bootloader interface.

6) Run Downgrade.cmd. Warning! Do not touch you pad while Downgrade.cmd is working. It'll reboot some times, and finally it should reboot into the bootloader (fastboot mode) when done and working window Downgrade.cmd will closed.

[OPCIONAL] If it is stuck in Intel logo, run Downgrade-2.cmd and finally it should reboot into the bootloader (fastboot mode).

7) Choose "SD download" to flash the firmware.

8) It should now reboot into Lollipop with root. Verify that root is working by running SuperSU.

9) Delete the firmware from the SD card.

Note: When the pre-rooted Lollipop firmware is flashed, a backup of the internal factory partition should be created. This file is named "Factory.img" and can be found in the root partition. You will want to copy this file to a safe place, as it contains the serial number and IMEI.

[MeMO Pad 7 Q&A, Help & Troubleshooting] pWEN:
The downgrade was only necessary for the initial installation of the pre-rooted Lollipop. That is, for those of us who updated the tablet to Asus' official Lollipop firmware (unrootable), we had to downgrade to KitKat before being able to flash the pre-rooted Lollipop firmware. Whether or not that was actually necessary, I'm not sure, as I never tried it without. I followed xda-log's simplified instructions to go from Lollipop .12 to .17, which didn't require KitKat at all. So perhaps naming the files "downgrade" is a misnomer at this point. Maybe we can recommend to new ME572c/cl owners to update to official firmware now before trying to install the pre-rooted versions, so they can at least be on the latest Lollipop.

I should note that I always completely wipe the tablet, never saving user data. Otherwise I keep it on the SD card.

Actually, now that I think about it, I don't think I've ever had to run downgrade2.cmd, and wasn't aware it was useful or even still existed until xda-log just linked to it. Hey [MENTION=3531407]xda-log[/MENTION], can you explain what downgrade2.cmd does that's different from the regular downgrade.cmd?

Difference is that downgrade.cmd assumes you're still in Android and it will try to flash the ifwi using fastboot and then reboot, otherwise it's identical.

[MeMO Pad 7 Q&A, Help & Troubleshooting] pWEN:
I Googled the error "failed to mount /sdcard invalid arguments", and one of the suggestions I saw was to format the SD card as FAT32 in Windows with "quick format" unchecked. Alternatively, you could use SDFormatter to do it. You might need to set the cluster size to 32kb, too. Seemed to work for someone. Did you try that? It's best to do with the SD card plugged directly into your computer (or an SD adapter of some kind), NOT while it's still in the tablet. I believe what happens is the quick format option only formats the partition it finds, while the slow option will format the entire card. Also, make sure you're using the cord that came with the tablet if at all possible. I've noticed that it does make a difference (or at least it did when trying to use a 28/24 high speed USB cable instead).

I saw that you're on Windows 10 x64, and the tablet is recognized correctly in Device Manager. Drivers shouldn't be an issue, then. Are you running things through Command Prompt as administrator, or PowerShell? Use CM as admin if you're doing PowerShell, I had issues with PS and I'm on the same OS as you. You shouldn't have to use the ADB method. If you can get the SD card recognized properly again, following xda-log's instructions should be all you need. You should also redownload all of the files for those steps and verify that they downloaded completely.

I get stuck at the step 4) : when I switch on the tablet pushing simultaneously on + and - Volume button and then on Power button, I see inside the windows 7 device manager DnX USB driver and Moorefield Device but after more or less 1 minute, the Moorefield device driver is replaced by a MTP USB driver.

In the step 4), you also say that one should check in the PC device manager that appears asus android bootloader interface.

Actually I don't see listed in the device manager any asus android bootloader interface, at least described explicitly this way.

Is it necessary to install iSocUSB driver present in the Downgrade.rar ? Should downgrade2.cmd be used ?
