[Android Q&A, Help & Troubleshooting] lukoidus:
Dear friends,

I didn't find Lenovo IdeaTab S6000 related discussion, and all threads related problems similar to mine - didn't help resolve my problem. That's why I post here. Anyone with advice what else to try, how to proceed - is welcome.

My tablet is Lenovo IdeaTab S6000-H, with 3G modem, 16GB memory and MT8389 processor.

My problem is - when I turn on tablet, Lenovo logo is dispalyed, I hear some sound, logo is animated, then - it gets silent, logo gets static. It may last like this as long as battery lets.

What I did - I wanted this tablet to be a gift, and I really needed needed multiuser profiles enabled. So the only changes were towards reaching this functionality. Here's what I did step by step:

I rooted the device as this instruction says: http://rootinghub.com/root-lenovo-ideatab-s6000-h/

I used Framaroot 1.6.1 for rooting, downloaded from here: http://xdaforums.com/showpost.php?p=37508806&postcount=1

I wanted to connect the device with laptop (Windows Enterprise 64 bits), but the device wasn't recognized by Windows. This instruction helped me: http://stackoverflow.com/questions/...ct-a-lenovo-ideapad-s6000-to-windows-7-64-bit. I updated [Google.NTx86] and [Google.NTamd64] sections with following:

;IdeaTab S6000

%CompositeAdbInterface% = USB_Install, USB\VID_17EF&PID_75E2&REV_0255&MI_01

%CompositeAdbInterface% = USB_Install, USB\VID_17EF&PID_75E2&MI_01
​

Once I connected tablet to laptop, message popped up informing IdeaTab S6000 has been connected

What I really wanted was multiuser support. I followed this instruction and it worked like a charm: http://mlagerberg.com/post/56229890887/no-multiple-user-profiles-on-your-android-4-2-2-yes-we

I added second user, and I was able to switch from one profile to another

However, once I rebooted tablet - multiuser support was missing (pm get-max-users command returned 1). I realized I had to add fw.max_users=8 line to the build.prop file, as this instruction says: http://xdaforums.com/showthread.php?t=2275350. I added fw.max-users=8 as the last line (hit enter afterwards) to build.prop, editing the file as this instruction says: http://xdaforums.com/showthread.php?t=1948558

Then I faced the issue I can't overcome:

Once rebooted - Android freezes when the initial logo is displayed

When I try to connect the device to laptop and use ADB - HTC Desire is detected, not the IdeaTab S6000; I can't use adb, I can't get to the device with adb shell, adb kill-server did not help

I tried hard reset (factory reset), cache reset - with no success

When I put tablet into adb recovery mode - the device is detected (by adb.exe, windows) with 0123456789ABCDEF id, but adb.exe can't connect - and the device is shown as HTC Desire under Windows' Device Manager

I tried sdcard update with Update Zip Packager 3.0 I found here: http://www.mediafire.com/download/7j9z6c75mycqll3/Update-Zip-Packager+3.0.zip with no success - I get installation error with updates as simple as doing nothing but printing welcome message

I think the issue is with build.prop file - either the extra line I added, or file's permissions - I didn't verify file's permissions once I updated the file - but I can't find a way to mount Android's file system so I could fix it from my laptop

Thanks in advance for any help how to recover my tablet...
