After trying to root my tablet with ZenFoneRoot, my Tablet went into Demo mode and I couldn't use it at all. I tried flashing with the classic ASUS method (putting the firmware on the SD and updating) but after the update completed, demo mode was still there. So I went into fastboot mode and did a "fastboot wipe system", realising after that I can flash everything except for the system/ directory, which was not a .img file (duh, silly me).
If I select recovery from DroidBoot, I get a message saying "Installing system update" followed by "Error" and that's it... no recovery menu, no nothing.
What should I do to recover my tablet?
Here are the contents of my update zip file from ASUS.

After some research I flashed the WW_MeMo_Pad-11.2.3.17.3-2014100 droidboot (fastboot.img), boot and splashimage and now I can:
fastboot -w -i 0x0b05 flash update UL-K017-WW-11.2.3.21-user.zip
But I get the following error
E: unable to rename file /cache/update.zip: Cross-device link
Tried doing a
fastboot erase cache
without any luck...
Do you guys have any ideas?
Also tried creating a yaffs2 image using "mkyaffs2 system/" but I get a zlink: Invalid Arguments error
A few days later, I contacted Asus, explained the problem and they asked me to send my tablet somewhere out of town and I have to pay for the service (which I think will cost me 50% of the tablet's value). Well this didn't help at all.
I even tried writing a bash script that would fastboot flash system/path for every file in the system directory (yes, flashing ~1000 files took me 30 minutes). But the tablet won't start, even though the files are there and I wiped the system & cache partition before. I still don't understand how the recovery option works or why "wipe data" gives me an error. All I need is a valid system.img file, that's all.
From my research, I'm starting to think that the .zips are signed with SignAPK.
Sorry for asking this question, over and over again. I just want to share my progress with this, seeing that there are some posts without replys regarding this product and with the same problem).
What if I compile Android, copy the libs/ and etc/ directories and flash the resulting system.img (will try this tomorrow).
Thank you!

I am having the same problem .I cannot get into recovery mode,as u explained in above. i think RootZenFone app only works for android:4.3
Thanks for sharing
Same boat here
I tried rooting my ME70C/K01A with RootZenFone-1.4.5r.apk.
Unfortunately I tried it after the 4.4.2 update and now I seem to be stuck in some sort of demo mode. There's a blue icon in the notification bar and I occasionally get a pop-up dialog saying that demo mode has stopped.
I purchased it just this week so I'm thinking back to the store it goes. Maybe I'll just stay with my Motorola Xoom..

Well what I did since the last time I posted was:
- I successfully created a system.img image (using the tools in ADK) that I can flash into my MeMo pad, but the tablet doesn't boot even tough it was a successful flash Anddddd... I'm stuck at this point. Any more ideas?
To remove the offline demo in the notification in ME70C
To remove the offline demo in the notification
1. Enable developer mode in tab.
2. Download APD_offline_ME70C.zip and follow the step mentioned in contentupdateSOP0624.pdf.Once you go thought all the step mentioned .Tab will start playing the demo. (Note:-it will to update around 4-5mins, you check in notification bar)
3. Now need to deactivate the demo mode.
When the demo video playing on screen
Hold Back Key for more than 10 seconds, until is shows a page to key in password 741603.
The tab will automatically reboot and wipe all user data and deactivate demo mode.
Wait until factory reset complete. Once everything is finished tab will boot up with welcome screen
In this process the tab will be factory reset .So backup the data
I found the APD file and contenASUS website

I found this thread while looking for a way to unlock the bootloader but I did not do step 7 - I used 1.46r (attached), installed it, forgot network, went to airplane mode, ran Root Zenphone and then rebooted (not to recovery) and I am now rooted with Busybox installed and not in Demo Mode (and didn't have to disable it)

Chk out this video .This will help out deactivation of demo mode http://youtu.be/vptHAKTvoyw ...
If still don't work ,better to factory reset and try the step from the beginning
I cannot get into Recovery Mode. I boot into Fastboot, select Recovery mode, unit reboots, see the ASUS logo and then it hangs and eventually goes to a blank screen. Almost like the recovery partition is empty.
I was trying to restore my tablet back to a fresh install so I ran (in fastboot mode):
fastboot erase system
fastboot erase userdata
fastboot erase cache
How can I get stock recovery back? All I can do it get into fastboot mode. Unit has no OS on it now since I wiped the system partition.
Hi guys,
I'm trying to fix someone's Huawei G630-U10 but ran into some serious issues.
The device was stuck on the Huawei logo so the obvious choice was to factory reset to get the phone working.
When I go into recovery to "Wipe Data", it just says "Wiping data..." and then nothing. No formatting and no deleting seems to be done.
I downloaded the stock ROM (Update.app) and selected the option in recovery to "Update from external storage" and selected the file. It gives a message that it's rebooting into update mode to update, but then the device reboots and gets stuck on the logo again.
I've tried going into update mode (Pwr+Vol Up+Vol Dwn) and it just remains on the logo. So I guess only recovery mode works.
Since the recovery couldn't delete anything, I suspect the storage is faulty or corrupted.
PS: the device just stays on until I force to power down. Then it just reboots automatically after a few seconds and remains stuck on the logo until I power down again. This happens as long as I don't physically remove the battery to end the loop.
Any suggestions or tips?
PPS: I've search extensively for flashing tools for qualcomm based huawei but no luck. The official site just hands out the update.app firmware which only works in update mode (which doesn't work in my case).
hi! i have a rooted alcatel 1040a (android 2.3.6) in which I deleted many apps and installed Clockworkmod recovery and i wanted to install a new Rom, so i did it but accidentally deleted the backup. So now i'm not able to get through the configuration menu (because it always restart at some point, for example when asked about my mail it says: the process had stopped and take me back to the language selection screen), so i'm not able to access settings and i can't connect it to my pc. When i try to update from a zip file (stock ROM/CWMD Rom or whichever Rom) it says: signature verification failed.
Also, if i enter recovery menu (cwmd menu doesn't appear, just android menu) i wipe data and cache but if i try to install a ROM i can't. i read that i may be because the SD became corrupt.
Having my pc unable to recognize it and unable to reach the phone main menu, what can i do???
thanks

Hey guys, so I tried searching on google. Because my phone stuck on "OPPO" logo so I did enter recovery mode and wipe data/cache. Reboot. Still stuck. Tried wipe again and this time i downloaded stock rom for my model and install from sd card.. But it stuck on updating! And I tried it again many times. Until I can't boot to recovery mode.. After I press volume down and power button it vibrates and shows the screen that before the "language selection of recovery mode" but it does not go after that.. It just infinitely restart like you just entering recovery mode! Can anyone help me please... I'm desperate for this phone.. What I only find on internet is methods to flash roms but I cant even go on recovery mode now.. Please any help. thank you.

Well first use a pc or a different device with an SD card and google "new oppo joy 3 update" then put it in your SD card and put the SD in you oppo and then open your recovery mode and Install it from "update from local" and search the place you put your JOY3 update file and choose it then let it download by its self and WALAH! You phone is back with you
P.S. update it in the "system update app" when its start functioning again and let it update fully
And your problem is cuzed by an half downloaded firmware or a broken firmware cuz I faced the same prob ones as well...
where site i can download the update of oppo?
