Who wants to use camera on tablet?

64bit depends on if we can get all the needed files in 64bit. 32bit files are in the stock rom, we will see. Maybe we can use files form the Nexus Player or Xiaomi MiPad 2.

PS.: Would you (all of you) want to see a MiUI port?

I would rather see a CM12.1 or even a CM13 port. Working camera would be great because i use the tablet and i guess some others too for skype video calling.

Since CM12.1 runs smooth on so much devices, i guess it would be running also smooth on the S8. I also like the theming engine from CM and i guess i am not the only one :)

So if you could port a stable CM12.1 Version with at least a working front facing camera, that would be awesome. For that i would definitly spend you a beer :)

Extract the files.

Change storage to external SD card.

Browse to the folder where the TWRP backup files are on the MicroSD card.

Select System and Data only

Upgraded to my S8-50 to Lollipop, now how do I root?

I had KitKat rooted with the russian/dory labs recommended program.

Recently I accepted the Lenovo upgrade to Android 5/Lollipop, and my tablet is no longer rooted.

So now how do I re-root? I'm quite willing and able to do several steps. I've done some phones by fastboot flash, TWRP, adb, etc, etc - I'm familiar with Linux shell, etc, etc.

Just not clear where to start. I have the S8unlocker, the Intel PhoneFlashTool, now exactly what partitions do I flash with what?

Then how do I get into a shell with root privileges?

use latest flash tool

put tablet in 'fastboot starting' mode (turn off-hold up and down volume and power all down..as soon as it vibrates only release the power...it will go to a black screen with fastboot starting words on screen)

forgot...do the unlocker now..

(cmd session)

then again go to fastboot starting

open flash tool

then run bios repair

it may or may not get to fastboot normal screen...otherwise at least get it to fastboot starting screen again

do not disconnect or close flashtool

in same session now flash the kk rom (this is the TABS8-50LC_LTE_VOICE_ROW_WW14_S000200_150121)

once battery is charged more fully can breathe easier (twrp mode cannot show battery state at least I do not know of a way but maybe keeping it charging in twrp screen for 1-2 hrs should help a lot imo)

one thing about bios repair...you have to run it when in fastboot starting screen

and with latest flashtool (not sure if you need to check or uncheck sparsing in options in the tool itself but try both...it is not like you are flashing a big rom so would not matter I would think but try anyway both checked and unchecked)

i also checked some options when installing flashtool (not standard install) so see my snapshots in my links-see if it helps..the 5.2.4 version

about s8unlocker...in my case consistently it sits there doing nothing...what I accidentally discovered is to run concurrently the temp TWRP recovery procedure which also starts/restarts adb...only type ACCEPT and let it go to next panel while the s8 unlocker has already started...then you will see the s8 unlocker process to suddenly continue and flash the esp image (something to do with adb at least on my computer/laptop communications port) (may say failed, success etc....see the image of my cmd window when it flashed with success...you may see something similar...all these are in the MS drive links (there is a word document that has this info) I provided in an older message that is referred to in the above message url)
