Hi, I have a Window N11 tablet which is one of those cheapo ones but want to try and get it working for the kids to play with.
When I power on, it displays the 'N11' logo and then recovery system v1.3.35.
The next message is "E:check failed, Recover failed, please reboot and recover again!"
The only option I can select is 'Reboot system now'.
Remaining items that I can't select are factory reset, system recover, update from sd card and update from udisk.
Can anyone help please?
Hello experts,
I've bought a Huawei u8860 today but when I try to switch on, it goes automatically ( without push any other buttons ) in recovery mode.
I've tried to wipe and format cache, but once rebooted it goes always in recovery mode. The phone is brand new, unboxed today from a box with security stickers.
I've tried to update software from sdcard with its original firmware but it fails with this error:
-- Install /sdcard/dload ...
update package's ext name error.
E: ota_pre_update error.
Installation aborted
I don't think it is a software problem, but an hardware error. Do you agree?
I need an advice from you: try to flash again o give back the smartphone to the store?
Thank you
Stefano

I think if you download the official firmware from huawei, then put the dload folder on an SD card, then flash it (hold the + - volume buttons and power button in until there comes a screen of installing firmware) then it should be ok.
if not, you can always look at this post

hope it helps!
I remember i had the same issue once.. i installed STOCK ICS .4.0.3 via dload method.. and than everything worked fine..
i guess it might be issue of faulty recovery.img file
Please help, Android noob here.
I purchased this Zync Dual 7 Plus(Haipad HD 7 Zync Edition) (Zync Z930 Plus in the Manual) and became fascinated by the world of Android OS. My problem is I downloaded Chainfire 3D app from Playstore as recommended by my friends. After installing, it require a reboot so I restarted the tablet and then I'm stuck on the boot screen logo. I manage to get to the recovery page using ADB reboot recovery command but my tablet only has a power button. There's no physical volume buttons everywhere I looked so there's no way I can reach the "wipe data/factory reset" option. ADB Devices command can detect the devices but it is giving me weird serial number as 0123456789ABCDEF, Fastboot is not detecting the device. USB Keyboard and touch functions are not responding when I'm in Recovery page.
What I have done so far...
I've read several solutions and one of them is to flash the tablet using the ROM provided by Zync support. DL it and open the RockChip Batch Tool but the tool is not detecting my device so I can't upgrade.
Also DL the LiveSuitPack 1.07 but also, It is not detecting the device and from the instruction given, you need to hold volume button again which I don't have.
Please Help by providing easy step by step process. Thanks in advance
i have the same problem..it just happened this morning. have you find any solutions so far.. please help me

Manage to factory reset
Guys, I bring the good news here.
I manage to factory reset the Dual 7 PLus which have stuck at that damn ZYＮＣ before. what you need is flash command ur devices into e3 recovery by using "adb reboot recovery"(please refer to google for that). once you device start to reboot after u enter the command, straight connect it to a external keyboard via male to female input. then u can control up and down in the e3 recovery mode by using arrows button in keyboard. I manage to do it with dc power supply connected. choose wipe/ factory reset. wipe all data. then reboot. unplug the keyboard and you will have a new dual 7 with no zync logo again. GOod Luck guys.:victory:
Wait for the external keyboard
Thanks.. i will try. i dont have external keyboard now.
Hi xAthena... may I ask you how long it takes for the haipad zync to charge? 'coz I'm planning to buy one. thanks )
THANK YOU

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

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)

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.
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...
