Man i solved that problem and im a developer and software repairer.this frimware in size of 3.14GB is not for some imei but accidentally introduced.if you go to simple recovery select download latest virsion and recovery and wait for download end and install frimware after this update phone work normally
(Simple recovery after boot crash automatically moved on but if dont go keep vol up+power to input that page
After all and setup done do this steps in normall mode
1.turn off cellular data
2.connect fake wifi hotspot or any modem without internet connection
3.go to settings>about>software update>3 dots on right top>settings>automatic download update>click to turn off
4.go to settings >apps>software update>permissions>telephone=turn off
So(at this page find write system and turn off)
after all if you connect wifi you see the update coming at same build and binary in 3.14GB but dont download and click on: never check for update
And end.you did it

ROM\bootloader corrupt

Hi everyone
I have installed custom ROM and CWM recovery from another forum(which is currently unavailable)
Phone worked perfectly a couple of months, then it turned off and i couldn't turn it on.
Phone repair service recommended to change motherboard, but i refused and took phone back.
Fortunately, i could enter bootloader menu after that :victory:
But still some problems exist:crying:
Problem1:
when i turn phone on, it shows HTC logo for some time and then turns off.
Problem2:
when i enter bootloader menu and try to enter Recovery - phone shows screen with HTC logo and warning "This build is for development purposes only..."
Seems that i need somehow to restore Recovery and then try to flash new firmware.
Or maybe there is some method to flash ROM directly from PC(via fastboot), i tryed to flash Recovery, but no result
Thanks in advance and sorry for my english

ASUS MeMO Pad 7(ME70C)

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)

Hi I have the same issue, but I have no success with "Hold Back Key", when video is playing his entering after few seconds in full screen and back key from the screen dissapear. Please can you help me with that. Thanks!
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.

Galaxy S3 GT-I9300 Failed to mount /efs

Hello a few days i restored my galaxy to factory settings from inside the own phone settings everything was working fine until a couple days ago the phone started to rebooting every now and then
Right now is stuck on the samsung logo after you turn it on and in the recovery menu i got this error
E: failed to mount /efs (invalid argument)
I try to wipe the cache date and even doing a wipe from the recovery menu but nothing when the phone turn on and gets to the samsung logo it stays there a while and reboots again
I try doing this instructions from this post from another forum
The key for me was selecting the second item in the Tools menu (Firmware Upgrade and Initialisation?) - it seemed to bypass that whole 'connecting' process and just went to work. Here's the writeup that I put together (I need to insert the Kies screenshots that I captured).
- if you don't already have the Kies software installed on your PC, download it (just search Google) and install it. The first time it runs it'll update itself to the latest version so make sure you run it once before proceeding.
- put your phone in Download mode: with the phone completely off, press and hold the Volume Down and Home and Power buttons simultaneously, and release them all when you see the Samsung splash screen
- connect the phone to your PC with the USB cable that came with the phone
-- if you've never had the phone connected to your Windows-based computer before, you'll see messages about installing drivers, etc - just wait until this is done (may take 5 or 10 minutes) [I don't know what happens if you have a Mac - it probably just works]
- in the Kies software, select the second item in the Tools menu and just follow the prompts to enter the model number (in CAPS) and IMEI/Serial Number (both found under the battery - it's ok to remove the battery at this point)
- the Kies software should start downloading the correct firmware for your phone from the Internet; once that's done (depending on your Internet connection speed) it'll begin downloading that to the phone (this probably takes 10 minutes or so)

You can try flashing a recovery (cwm official is best) via odin but most likely you'll need to flash a stock rom, definitely if the cwm flash doesn't solve it.

[Request] Tips to save a phone that restarts itself

Hi all, my question prescinds from a phone particular model. The problem is that for some sort of software issue, the phone restarts itself after few seconds that rom unlock appear. I'm sure that is a sw issue because in recovery mode it stays alive and when he does the application update after a dalvik cache wipe, all goes well too!
It's not possible to enable usb debug because it restarts too soon and in recovery (cwm) it's not possible to connect via adb. It's not a rooted phone. Also in safe mode it stucks in bootloop
What i can do before a factory reset?

Looks like its bootlooping ... Yes its a software issue ... I don't think u have any option other than factory reset ... Take a backup first before u do that...or perhaps u can use a logcat if u know what it is
i will try to take backup in sd card and retrieve some useful data from this.
how can i use logcat if can't connect through adb?
