Correct. I actually never updated since I got my tablet, so it is still on TABS8-50F_140929, version which tablet comes with it out of box. I know there were at least two/three small updates pushed since then (depend on which region you are on, USA, Euro, etc). And one of these small updates changes the DPI, which was suck because it changes 240 to 320. I am not new to Android nor this is my first Android devices, I have never seen a company changes DPI with incremental OTA update...this must be first. And these small incremental OTA updates does not brings any big update or improvement. I downloaded them and checked the contents of these updates, mostly app updates (their lenovo apps), that's pretty much it.

Obviously, there's lollipop update should be pushed to our tablet very soon (I am guessing), keep in mind that to get this lollipop update you have to be pure stock firmware with all small updates, but remember once you get Lollipop, there's no root method yet (if Root and Xposed and Root apps critical for you, you should not get lollipop update).

I read that some of Lenovo's lollipop updates failing on users device even if users are on offical stock firmware (check https://forums.lenovo.com/t5/Lenovo-Android-based-Tablets/bd-p/lt02_en), so that's probably why Lenovo has not fully pushed lollipop updates to all devices yet...

Today I found out a weird thing, I always charge my tablet after it reaches around 15% but this time I forgot to turn off the WiFi and found the tablet on 1% battery, after a while I got a popup that said "your phone will shut down" or something like that. Although it didn't shut down even after a minute. This got me thinking that the battery might be badly calibrated and the software is reporting a wrong value

We can get root easily. Some pix. (I have SuperSU.)

Just you have to boot the old KK droidboot, then run CWM.

Now you can flash supersu zip.

It can be done by:

power on the device while hold both of the volume keys

if will tell you "starting fastboot..."

run these commands in the folder of any KK rom

fastboot flash osloader efilinux.efi

fastboot boot droidboot.img

now you can run CWM and get root. :cool:

I'll wait until a full root method appears. I wouldn't want to go messing with the bootloader.

We still need to have full firmware lollipop zip file (no, not update.zip, which has partial update)..

my friend, that's workaround, so don't do that. You seem like you have root, so go download normal xposed from here: http://xdaforums.com/xposed/xposed-installer-versions-changelog-t2714053. This is version 2.6.1, make sure you download KitKat, not lollipop...ok?

[Android Q&A, Help & Troubleshooting] jazzespresso:
be careful with xposed, don't go crazy with it, even if it works for x86 devices (like our tablet, asus, dell), some exposed module causes soft-reboots.

It was pretty much confirmed anyway since someone on this very thread is running it already.

But now it's as official as it can be.
[Android Q&A, Help & Troubleshooting] jazzespresso:
that one is not full blown lollipop, it was an update, and believe it was a leak version, not final version. Based on Lenovo, looks like it will officially pushing lollipop Quarter 3, 2015, sometimes middle of summer perhaps.

hopefully, they will make it available as fulll firmware download, so that we can download it and somehow able to find a way to root it.

I recommend the new twrp, I still have to add something's so it will backup the recovery.img fastboot.img and esp.img

This tab has some quirks but I'm loving it.
[Android Q&A, Help & Troubleshooting] jazzespresso:
It is very good tablet for the price. Like you said, it is a bit different than other x86 devices. Not having full blown recovery makes it hard for custom ROMs.

I did see yesterday you released new twrp, but haven't tried yet. I actually like TWRP more than CWM :)

seems like you got the tablet :D
[Android Q&A, Help & Troubleshooting] social-design-concepts:
At $109 open box it was a steal

Being UEFI at least makes it closer to a traditional computer.

Intel doesn't seem to have a standard format when it comes to the MID market I believe there is 6 different image formats really complicates things, probably why third party development is so low.

If the efi application didn't check for signatures the tethered recoveries could install custom ROMs but until someone figures out how to get around the uefi certificates / keys it can't be replaced by one that doesn't check signatures :(

so now that twrp works I plan on screwing with the uefi

Quick question so this devices has 2 fastboot modes?

you may dig into Russian Lenovo forum (Google translate is your best friend here). Anyway, I pinged Xakep couple times, but no response from him...

At $109 open box? Bestbuy? it is a steeaaaaaal!

It is really nice tablet, too bad that it did not get a lot of attention when it released way back. I am not saying this is perfect tablet, nor comparing with Galaxy Tab S 8.0, but comparing how much this cost and what you get :p

i am sorry but what is the point to have L stock ROM when you can have LC ROM ??
[Android Q&A, Help & Troubleshooting] jazzespresso:
Your tablet originally based on L stock ROM, now when you change it to LC ROM, you may not get official updates of L ROM from Lenovo.

but this is not end of world of course, whenever there's new full firmware of LC ROM, you can flash it, so your tablet up to date with official release.

i had similar issue with my Samsung Galaxy TabPro, i was using non-samsung smart cover, and got the similar issue, then I bought the original Samsung cover, it went back to normal.

Remember some 3rd party smart cover's magantic thing is way too strong or not placed correctly..etc, which may causes the issue..

well, if you think the orginal DPI level set to 240 dpi, i am considering using the 240 dpi since that was original setup. 320 dpi may seems better, but some apps screen may cut off - some people even posted some screenshot at official lenovo user forum, you may check that; (http://forums.lenovo.com/t5/Other-Android-based-Tablets/Re-Tab-s8-50-Latest-update-changes-resolution/td-p/1825209.

[Android Q&A, Help & Troubleshooting] lilhaiti:
I get all of that, but when I compare similar apps on my tab and my phone, elements on the screen should not be smaller on the tab which they are at 240. To each his own I guess, hey thats why we root, make it your own.

I for one would be super stoked to see windows as a viable option for this tablet. In fact, the prospect for running multiple operating systems was one of the underlying reasons I purchased these devices. My guess is that far more on screen time might be possible from within a windows environment. 6-7 hrs is pretty sad for the beastly 4290mah battery (or is it 5700mah?)

Install the driver again, then it should work!!

If not!! go to device manager and select lenovo device

go to update driver device

click 'browse my computer for driver software'

click 'let me pick from a list of device drivers from my computer'

select the right driver (in my case: lenovo composite ADB interface)
