ASUS MeMO Pad 8 (K011) ME181C Recovery Guide

The following is a list of what we can currently do with this tablet. It assumes firmware versions with the WW prefix (WW-3.1.23.1xx)
.​

Root Status: Obtained
Bootloader: Locked
CWM Recovery Possible: Yes (Tethered)
Custom ROMS: None


The following information is for recovering your tablet and obtaining root only. The bootloader is locked on the device at this time.

Tethered CWM recovery
This is a temporary solution to unsigned loading. The bootloader on the device is currently locked, so after rebooting, it will revert back to standard recovery. Use this to restore to a stock firmware or to install SuperSU.

  1. Download the official firmware and extract it.
  2. Rename UL-K011-WW-3.1.23.172-user.zip to user.zip.
  3. Copy user.zip to the root of your SD card.
  4. Enable USB debugging on your tablet.
  5. Run Launcher.bat.
  6. Type ACCEPT.
  7. Choose option T3.
  8. This will reboot in to the Tethered Recovery.
  9. Choose Install Zip from external SD card.
  10. Choose user.zip
  11. Reboot once finished.


Bootable Image for Recovery
This file is to be used if your system will not get past the Asus or Intel logo. Boot the system using Volume Up and Power. Once the logo appears, let go of power. Once in DroidBoot, use fast boot to flash the boot and system images. This is provided in case signature verification fails on the official images.

fastboot flash system system.img
fastboot flash boot boot.img


This file also contains adb and fastboot. If your tablet is not detected, try the Asus drivers.
Reboot the system and use the CWM tethered recovery to reinstall the official firmware.


OTA Updates
If you’ve recovered from the official firmware on the Asus site, you’re probably sitting at version WW-3.1.23.172. Here are the OTA updates to bring your system up to the current version of WW-3.1.23.189. There are two different OTA updates available here, so the process will need to be completed twice. Update 172 to 183 and Update 183 to 189.
  1. Boot in to recovery, press the volume keys several times and install from ADB.
  2. Extract the RAR file and rename the files update.zip.
  3. On your PC, open a command prompt and change to the directory containing the update file
  4. Assuming ADB is installed on the system, type: adb sideload update.zip
  5. Once the process completes, reboot your system and update apps as needed.
  6. Repeat this process for any additional update files.

Recovery image
This is the default recovery for the tablet. If you get adventurous and try to flash another one, this may come in handy.

can you explain

All thanks to vampirefo for his work on this.

FB Tethered Recovery Launcher

Kind of curious if this method will work with the other versions of the tablet to allow SuperSU to be installed. Anyone want to try it?

Long story short, I screwed this thing messing with the framework. For some reason, the official firmware from the Asus site was failing signature verification when trying to reinstall. Someone managed to grab a stripped system image that at least gave me a launcher and USB debugging. This beauty allowed me to get the firmware installed and everything back to normal, as well as installing SuperSU.

If you have any trouble getting the tablet to show up in Windows, the Asus distributed drivers work like a charm.
can you explain in lamens terms or retard terms what this means you found? so me and others
as well can understand ? Please and thank you i have a ASUS MEMO Pad 8 Me181c Rooted With Frame1.4apk it took me to demo and i turned it off and rebooted and now it just goes to The ASUS Logo and then Intel Logo and Stops . If i could find a way to install CWM on this maybe i could get somewhere but all i see is people talking about it but no video tutorials , or walkthroughs
Any Help Would be greatly appreciated

1. https://cloud.mail.ru/public/2b47381cb37c/ADB.rar - This contains adb and fastboot if you don't already have them installed. This also contains the system image that we're going to use temporarily to get this thing restored.

2. Hook it up to your computer and load up Fastboot on the tablet (Volume+ and Power while booting. Let go of power after the logo shows up).

3. Flash the System image ( fastboot flash system system.img) followed by the boot image (fastboot flash boot boot.img)

4. Reboot.

5. https://www.androidfilehost.com/?fid=95857557620392052 - Next, we're going to use a temp version of CWM-Recovery to reinstall firmware. Enable USB debugging, run launcher.bat, type "ACCEPT" and choose T3.

6. You'll auto reboot into CWM-Recovery. Grab the official firmware from the Asus site and install the zip from SD. Once complete, you'll need to reroot the device most likely. If you have a SuperSU zip, install it after you've restored the system.

You're done. This also opens us up for just about anything. :) Go play with your system. As long as you don't mess up your boot loader, this should save you.

Hey guys,

I have a Asus MeMo Pad 8 - Pro 7 Entertainment Pad. Now the model is K011 and the firmware starts with LVL bla bla bla.
Technically it is the same as the 181C and I also have managed to achieve root. Any ide if I could get the WW firmware and rom working on this?

UPDATE:
Using this method gives you version 172 of the firmware. Current version is 189. So here are the OTA updates. :)

To use these files, Start up the system in Droidboot, Volume+ and Power, go to recovery. You'll be sitting a broken android robot screen. Press the volume keys several times. It's give you some options. We're going to install from adb.
Unrar the update file provided, rename the file to update.zip and sideload it to the tablet. Once it finishes, reboot and wait for the system to update. Rinse, lather, repeat for 183 to 189.

Files:
OTA update 172 to 183
OTA update 183 to 189


Note: This is only if the OTA updates aren't pushing to your device. If you've got them, you can skip this.

fulishone: If the intel tether works for you, you could always try it, but I have no idea if it would work or not. If you have your system backed up, you could always give it a go and restore if it fails.

I'll try to compile everything in to a more readable format later. I just want to get the info up right now. A lot of people were semi bricked either because of a root gone bad or file system problems.

Ok, I am not new to flashing and custom roms and so on, but follwing your guide above, I should first flash .172 and then use your update files for .183 and the .189?

What do you mean with Intel thether?

Best regards

Yep. That'll get you updated to the current firmware. I contacted ASUS yesterday and sadly, there are no plans on bringing Lollipop to this thing, nor are they interested in giving us an unlocked bootloader.
As for the Intel Tether, where the bootloader is locked, we can use a tethering method to access CWM recovery, but once we reboot, it reverts back to the standard recovery. This prevents us from using custom roms at this time. When it reboots, it checks signatures. The official firmware was not installing using the standard methods, so I used CWM to reinstall. That's why I included it above.

BBY builds

My guess is that this won't work with the BBY build. From what I understand no one has rooted an ME181C that has a BBY build. I also have not been able to connect the device to my PC. From reading this thread though it appears that to connect through the device drivers I need to boot into one of the recovery mode. Is that correct? I can see my sd cards okay when connected, but can't see the device through ABD.

I'm curious to know if the tethered method would allow a temporary CWM session to install SuperSU on the BBY line. I haven't seen anyone try it yet. If USB debugging is enabled, the tethered restore should try to automagically do everything for you. If you boot in to recovery, can you do a fastboot devices?

Thanks for posting this. It helped recover my tablet to 172. I see 172 on ASUS's website, but not the updates, and my tablet says it's up to date. Can you advise what 183 and 189 provide? Any new features or enhanced stability or performance.

Thanks in advance. Very much appreciated.

For some reason, OTA updates for this thing don't want to download. I've not seen too much of a change between them, but I applied them just to be current.

Yeah, strange that it won't update over the air. But thanks to your assistance I am running build 189. It may just be wishful thinking, but the device does seem a bit peppier. Thank you RemmyLee!!!!

[Update] Since updating to build 189, the device is much more stable and snappier. This was definitely worth doing. I don't understand why ASUS would not be pushing this out to everyone with this device.

Just wanna say thanks to the OP. Got my tablet back from the service center and was wondering why some apps were missing. Sure enough I was on WW...179. Nice to have updates and recoveries in one place. Great work!

Me181c not working...

Hi guys, I was using SoftKeyZ for about 2 weeks, I wanted to set my navigation buttons to it's default, so I tried using Backup of the SoftKeyZ, but when it rebooted the tablet, I lost my navigation buttons and indeed my notification and status bar. It rebooted again automatically, and this time when it started, I got an error which says: "Unfortunately, KeyguardTestActivity haas stopped", the error prevents me from unlocking the tablet and using it, so I cannot use it at all. I don't know how to go to recovery mode on my tablet, I used the button tips but it didn't work for me. I've downloaded the official rom from asus.com . Pleeeeeeeeeeeeeeeeeeeeeease, I need your help guys, you're my last chance... :(

should I do a complete wipe ?

Hi,
Thanks for the help in this thread.

I followed the instructions and successfully flashed the update firmware file. I was expecting for the tablet to be reset to original factory condition but found that all my apps ect were still there. I guess the user.zip is an update rather that a full ROM or should I have wiped everything first ?

I am have problems with the tablet such as Bluetooth has stopped working and wifi will only connect to very strong signal, (as in touching the router) which is why I wanted to completely wipe the device a start fresh.

f I wipe everything will the firmware file be able to restore the system fully?

Is there a complete firmware image file that can be downloaded any where ?

Thanks in advance for any advice

update : so fed up with no Bluetooth so I took the chance and did a full factory wipe and the system restored ok with the firmware file. Bluetooth problem solved, (Wifi did not, probably Hardware issue)

Thanks again

Signature failure

Thanks to your instructions, I've successfully managed to update my device to build WW-3.1.23.172, however, when trying to install 172 to 183 update I get a signature verification failure message.
Any ideas why this is happening?!

    OP

    thank you .. but where is ROM link? (EDIT: i found it)
    how can i root this tablet ( as you know i have problem for rooting) , and where is cwm link?

    Sent from my ZTE Grand S II LTE using Tapatalk

    CWM tethered recovery for these tablets is on first page of this thread. Factory reset first, (either through settings or in tethered recovery), then install the firmware (.191). Place Chainfire's SuperSU .zip on internal mem or sd card (tethered recovery will not recognize large sd cards like mine (64gb) flash it with tethered recovery. When you choose to boot back to system after flashing SuperSU .zip, it will prompt you to fix root, do not! Also, it will ask to update binary, with options of regular install or through recovery, you have to use regular of course, but it works.
    This not only gives some fixes, tweaks to performance that I have noticed now since using it saves you from having to do three flashes. Follow the OP directions as well. After downloading the .zip, rename a copy of it to user (user.zip) so it can be found with option of installing "user.zip" in tethered recovery. Also, note, after I installed, system popped up asking to install the update .zip again after getting to desktop! Had to go delete off internal memory.

    Okay All,

    I'm writing this to set up a clearer process for all of the things Remmy typed up. Remmy did an AMAZING job of putting it all together and deserves all the credit.

    Tethered CWM recovery

    1.) Download the official firmware and extract it.
    2.) Rename UL-K011-WW-3.1.23.172-user.zip to user.zip.
    3.) Copy user.zip to the root of your SD card.
    4.) Enable USB debugging on your tablet.
    5.) Use the link in RemmyLee's post #3 on page 1 of this thread ( androidfilehost.com/?fid=95857557620392052 ) to download a file called IntelAndroid-FBRL.7z. Inside, you will find the 'launcher.bat' file.
    6.) If it's not already, connected the tablet to the PC.
    7.) Run Launcher.bat.
    8.) Type ACCEPT.
    9.) Choose option T3.
    10.) This will reboot in to the Tethered Recovery.
    11.) Choose Install Zip from external SD card.
    12.) Choose user.zip
    13.) Reboot once finished.
