So...last night I decided to switch off doldy, rebooted and I didn't face the crazy backilight issue neither when watching online videos through chrome or locally via MX Player Pro. I don't know if it was the weather cause yesterday temperature drop significantly, so thermal service maybe didn't activate for screen brightness? :confused:

Hey guys, I am backing up through temporary cwm my full TABS8-50L_150618 (latest update - no carrier exclusive) software version and will upload soon. I have made a factory reset, didn't have in my sim card or enabled wifi during set up so this should be a clean backup for the latest L version. I will let you know for the download link!

Lenovo TAB S8-50L CWM BACKUP DOWNLOAD !!!

Lenovo TAB S8-50L

TABS8-50L_S000213_150618 (latest KK update - non carrier exclusive/unbranded)

CWM FULL DEVICE BACKUP

- This is a full backup from my Tab S8-50L. It was acquired using the temporary cwm recovery using social-design-concepts method explained here http://xdaforums.com/android/development/intel-android-devices-root-temp-cwm-t2975096

- Before doing the backup, I did a factory reset and I didn't setup my google accounts or other things in order for this to be as clean as possible (sim wasn't inserted also). The zip file contains the cwm backup folder from my external sd storage.

Ways of restoring your system

Method 1: restore through cwm

a. Unzip the "clockwork" folder and copy/past on the root path of your external sd

b. Restore your system using the temporary cwm recovery solution mentioned at the beginning of my post

c. Optional: once done, you can then factory reset your device

Method 2: flashable

IF SOMEONE CAN MAKE A FLASHABLE ZIP THIS WOULD COME VERY HANDY LIKE RESTORING DEVICE BACK TO THE LATEST KK VERSION. ASK ME IF YOU NEED ANY OTHER FILES

- DOWNLOAD FULL CWM BACKUP FROM MY GOOGLE DRIVE

https://drive.google.com/open?id=0B9M8_kmjGjueQ1Y4cGdhNnJzcm8

- THE BACKUP DOES NOT CONTAIN PERSONAL INFO OF ANY KIND

- THIS IS NOT THE ORIGINAL FIRMWARE THE DEVICE CAME WITH. IT IS A FULL DEVICE BACKUP AFTER UPDATING TO THE LATEST KK UPDATE

- I AM NOT RESPONSIBLE IF YOU BRICK YOUR DEVICE. DO THIS AT YOUR OWN RISK. YOU SHOULD RESTORE THOUGH YOUR SYSTEM WITHOUT ISSUES

- *** ATTENTION *** - THIS IS NOT A FLASHABLE ZIP (YET)

[Android Q&A, Help & Troubleshooting] itasoulas:
Yeah, if all goes well with cwm restore, you should be able to update as usual. I don't know if your tablet is branded and you receive updates from your carrier (I actually don't know if there's a branded version for tab s8-50l). Mine is not and I receive updates from Lenovo. This backup was done in case I screw up something and my tablet needs to be brought back to stock state. I haven't tested if it restores fine but the backup process was completed succesfully without errors
[Android Q&A, Help & Troubleshooting] Minto107:
Mine is branded yeah. I have custom bootanimation and wallpapers and my software is named 141124_PLUS(Plus is my carrier). I will give it a try ;) I really want to get lollipop next month because my S3 probably won't get it and my N4 can't be updated anyhow

How did u get CWM working?? Which trigger should I use? I couldn't flash it. It just boots into stock android recovery...
[Android Q&A, Help & Troubleshooting] itasoulas:
I believe this is needed to make a flashable .zip... META-INF folder and updater-script...I think I can do that. Trying now...

Trigger T3...this is not a flashable zip. You need to restore it via cwm.
[Android Q&A, Help & Troubleshooting] itasoulas:
Ok, I was able to generate the META-INF folder with updater-script and update-binary with a modded kitchen for KK and some tricks (!?!). I am attaching this here. Now it should be easy to collect boot.img, META-INF, system.ext4.tar.a and system.ext4.tar.b from post #555, archive them into a .zip and flash? Those with more experience you gotta give this a hand and also revise the updater-script to see if you find out any strange lines (or missing???)

Again, I may be talking bull... I am not experienced in this field of developing!

Unfortunately not. there's no custom xposed like GravityBox to work on our tablet to change the way it looks. Some of elements in GravityBox works, but if you want to change, say, notification bar or status bar, etc, it won't work.

It is the same situation if you check xposed general forum, for example on my Samsung devices (which heavily uses touchwiz skin top of it) there's WANAM xposed that specifically made for samsung devices, there's also Xperia version that made for xperia devices. I hope this make sense to you.

Hello guys I'm new to android and as Im reading here is it right that CWM Recovery is used when I want to back up factory settings if I want to get the tablet to the stock state when I received it ?? And what is Xposed Framework and Titanium Backup ??

Thanks ... I'm happy with the starting community for this tablet because I was a little worried that there won't be any support from you guys. I'm now reading throught forum to learn how to root and change DPI. And last question ... I wold like to remove than some apps which are system apps and I saw some app for it at play store is it working ? And some things that I won't miss as a new android mod tablet user ?? :D

EDIT: ok i found out what is CWM and there is a question .. is there a way to get back the default "Recovery" ??
[Android Q&A, Help & Troubleshooting] dwcasey:
A nandroid backup or Titanium Backup would be good backup solutions.

Be careful removing apps. If you want to receive updates from Lenovo, you will need to restore any built in apps you deleted. Freezing them might be a better option, but I have not testing that myself. Without the default Lenovo software installed, the Lenovo updates will not work.
[Android Q&A, Help & Troubleshooting] Yenupuri:
Yup. That is what I did as well. Did not care enough to unroot. Just restored the old build prop. Updated it. Rerooted it. Grabbed a beer. Called myself a genius :D

Are you able to share exactly how you did it to access it?

Were you able to disable secure bios?

Thanks!
[Android Q&A, Help & Troubleshooting] social-design-concepts:
Yeah I'm going to do a quick write up tonight about it.

As for Secure Boot it's actually disabled by default but there is two boot modes Android & Win 8.x , Win 8.x seems to be traditional uefi boot like you find on a desktop or laptoop allowing you to boot Windows or Linux efi binaries the Android boot mode I need to research more it always throws a certificate error when you try to boot anything that's not the manufacturers efi binary I haven't had to much time to play fell asleep watching Frozen lol last night. I'm only going to cover getting into the setup initially and disabling uefi fastboot so you can get into the setup using a keyboard instead of from android.

Personally I'm not going to put to much time into cm-12.1 with Android 6 coming out in November more than likely I'd rather spend my time getting the needed research done for a Marshmallow port.

Are there any Lenovo S8-50F tabs that don't have brightness dimming issue?

I saw a few topics with this problem and in all topics didn't saw anyone who said that problem doesn't exist. So it means that all tabs have this brightness dimming problem?

I am thinking about bringing the tablet to warranty for this brightness issue. But if the problem is on every tab then I better stay with mine.

Remove bloatware

Finally rooted my tab this weekend and started removing all the apps that I don't use; which added up to 780 mb.

My process:

Install full firmware from first post

Update to latest version available (150121)

Load thetherd twrp

Copy remove.txt to sdcard (adb push remove.txt /sdcard/)

Mount system in TWRP

adb shell

cd /sdcard/

chmod +x remove.txt

./remove.txt

(Optional) Perform a factory reset in TWRP

(Optional) Install SuperSU

Reboot

Note:

- I removed a lot of default applications that some probably like, just remove the line deleting this specific file (both .apk and .odex) from the remove.txt before copying to keep those.

-I will also upload all the removed files, in case someone uses my method and wants some app back (will update this post with the link once upload finished)

- Future update won't install, unless you push all the removed apps back

- Just install your favorite camera, contact, agenda etc :)
