Flash your rooted system.img and tell me if it all works:

Download Rooted_system_1380F_USR_S000118_1412151610_WW21

Now that you have the root, you can dump the kernel and recovery, if you need them (but first looks good number of your blocks mmcblk0p3):

Code:

adb shell su

kernel:

Code:

dd if=/dev/block/mmcblk0p3 of=/sdcard/boot.img

recovery:

Code:

dd if=/dev/block/mmcblk0p4 of=/sdcard/recovery.img

@McKebapp
your partitions of boot and recovery which numbers have? (mmcblk0p..?)

Ok, I've got root and I'm on FW 118.

On boot, a massage like "system isn't working anymore: do you like to wait, or should I stop it", appears.
When I stop it, nothing happens and the tablet seems to work normal.

Unfortunately the projector and WiFi are broken, from what I see.

- WiFi says "activating", and nothing happens
- The projector lights up for a sec, then the is just a very low light coming from that LED bulb.

I didn't reset it to factory state yet. I'll perform a backup and do it right afterwards.

How do I determine which of the mmcblk0p are correct?

First of all, thank you @bodivas for creating the 118 image

Something else: is beside me, anybody experiencing random freezes, when the tablet is in deep sleep state?
I've got to hard reset it, to restart it... :/
No difference between the old, but rooted software, nor the latest non-rooted OTA...

The exact moment I read this, my device had the same behaviour for the very first time.
1380F on 118.

What do you use to repack system?
Also I have not found where it "resurrects" this HD Security. I looked into the ramdisk boot, recovery, droidboot and no trace.It seems that their year integrated into the kernel. For the moment you can only freeze with titanium (license)

Code:

mkuserimg.sh -s /path/to/unpacked_system_folder /path/to/new_system.img ext4 /some/temp 1610MB
which results in
make_ext4fs -s -l 1600M -a /some/temp /path/to/new_system.img /path/to/unpacked_system_folder

With Security HD, I am clueless as well. Freezing won't help either. I installed SManager and created a script which after booting removes the app.

Partitions on 1380F:

Argh... ls -l --> Stupid me. I forgot -l.... :good:

Ok, I'm back to factory defaults. The System error is gone, but WiFi and Projector are still broken...

Here are the boot and recovery partitions: http://www63.zippyshare.com/v/52345583/file.html

To the freezing: I've talked to some of my direct colleagues (Each 6600 employees of my company got the 1380F for Christmas) --> Some of them also have the freezing problem...

Hello everyone,

for me the last update of the 1380 also bricks my projector and wifi?
Is there a way to fix it?

xterminater07 · Dec 27, 2014 at 6:47 PM

so the rooted image that bodivas seems to be breaking wifi and projector? This is bad on lenovo's part and needs to be fixed asap if this is the case since this tablet is their flagship for the projector.

Einer1987 · Jan 8, 2011 11 0 0

The official version works well.
Only the rooted version bricks Wifi and projector.
Lenovo has to update to 5.0 and implement dual boot for linux and windows

About Security HD. Just a thought.. Could have something to do with Intel Device Protection Technology https://software.intel.com/en-us/an...-technology-for-android-on-intel-architecture ? The description sounded familiar.. "Integration with anti-malware client, available for Atom Z3xxx processors", etc. And I can see with root explorer there is some files named *intel.security* in my system folders.

hi when I trying to flash it, phoneflash tools is freezing in 65%

Go on Phoneflash to: File-Fastboot-Options-General
and set "Force Sparsing" to 500mb

We work for the same company lol (Systemhaus Mannheim).
The first days after the devices were sent out, ebay.de was flooded with them, as low as 360 euros (500 new at that time).

Hey. I have a request for you. Please give me a link to the original rom without root to 1050L. Thanks in advance.

Thank you for also looking into this.
I had a look through my system, but the only intel related components I can find are "com.intel.security.service" /system/app/SepService.apk and "SecurityManagerService" /system/app/SecurityManagerService.apk.
Both of these are less than 100kb while Security HD is 9MB, so this can't be it.
Might be a good step to look though.
Edit: it seems (at least from the seemingly outdated docs on the Intel site) that this comes with McAfee only.

Besides, I found something else after integrating updates (I ignored the easywhatver folder):
After every reboot, Lenovo PowerManager asks for root permissions, as if it got reinstalled on startup.

@bodivas:
will give it a try with the value you mentioned, thank you.
Shouldn't it work with any value that is just big enough to hold all files, or does this define the maximum possible size, independent from how much content the image has (and how big it will actually be)?
I'll try to create an image that contains patched boot, esp, fastboot and rooted system 118, does not wipe data, and the recovery for copying via ADB.

Same here - Düsseldorf :victory:

BTW I experienced the random freezes as well.

Still hoping for a custom rom with 5.0

McKebapp · Dec 28, 2014

I'm back at the non-rooted OTA

xterminater07 · Dec 27, 2014 at 9:57 PM

I don't think having lollipop will allow dual boot. Someone has to unlock the bootloader for us to have a potential of dual booting.

J0uns · Feb 1, 2011 109 50 0

For me personally I don't want Windows on my yoga. Just want a fluent experience of Android. At the moment my yoga just feels slow and underpowered

subworx · Oct 8, 2010 245 159 0

I'll take a break until after New Year's.

The tablet suddenly decided to take 3+ minutes to be recognized by adb after a device reboot or reconnect.
MTP/PTP modes both don't work at all.
Rebooted the device, rebooted the PC, did not change anything about the setup (except running Eclipse to code the Xposed module).

I repacked the image, but can't and won't flash it now.
Tomorrow until Friday I'll be away from the PC so no chance to test.

Happy New Year to everyone

I hope not.... There is no decent Root for this version and 5.0 will be much harder...

bnk989 · Dec 29, 2014 1 0 0

would it work on a wifi only version?

would it work on a wifi only version?

just woundering... TNX

McKebapp · Dec 29, 2014 at 7:19 AM

Could you please precise a little more?
Which FW on which Tablet, as this thread is a little mixed up...?
