Long time lurker, first time poster.

I uploaded it to my Google Drive as well in case anyone wants a second link. I tried the update as well and it doesn't go through normal means (from reading the previous posts, it appears there's much more work involved). I'm not that brave, nor am I that knowledgeable, so I'll have to wait until there's something a little more stable.

Side note: I guess you'll have to PM me for the link, since I'm new I can't post hyperlinks. :(

I can't wait to get Lollipop onto this tablet, I hope it's soon!!!

Battery problem?

Hello,

any idea why the battery does not show all the properties?? And if I'm right, the battery capacity should be around 4.200mAh not 5700???

[Android Q&A, Help & Troubleshooting] jazzespresso:
thanks....downloading...

To all;

we just need to wait and see if we could able to find a safe way to flash this lollipop update (preferably, keeping the root), so don't rush into that if root is important for you.

I am hoping hopefully someone from lenovo Russian form will post pre-rooted files for us!

[Android Q&A, Help & Troubleshooting] highHopes:
Hello everyone, I've installed the update from microSD, my device wasn't rooted. I have to say that this ROM is quite stable, wifi, BT, Dolby Digital, camera etc. work fine. Some apps crash sometimes but I think only those that are not compatible with lollipop so far. The biggest advantage is much longer battery life, I would say it is +15-20 % better than 4.4.
[Android Q&A, Help & Troubleshooting] RaawrItsTomi:
Oh my god i'm so excited for the battery life then

Edit: Hopefully we will be able to get an adequate screen on time now
[Android Q&A, Help & Troubleshooting] jazzespresso:
what steps you did to install lollipop update.zip? can you put step by step, so that others will benefit?

another question: was your tablet rooted previously or it was stock (nothing touched no change in system files)?
[Android Q&A, Help & Troubleshooting] jazzespresso:
by the way, you need to re-install the apps that crashes, remember Lollipop is ART based, while 4.4.X is Dalvik, so I may recommend you to uninstall them and re-install them thru Google Play.
[Android Q&A, Help & Troubleshooting] highHopes:
I did cache wipe and factory reset after update...

---------- Post added at 08:29 PM ---------- Previous post was at 08:22 PM ----------

The first update was OTA and this ROM was rubbish. After couple of days there was new update available but i wasnt able to intall it OTA. So I copied update file to microSD. Then I pressed pwr button and volume +, chose "apply update from external sdcard" and found the zip file. Thats all. My device was stock. I dont root devices in guarantee period.
[Android Q&A, Help & Troubleshooting] MisterSandman:
Now that HighHopes has a properly updated tablet, is there anyway to image it so the rest of us can utilize it? Or do we have to wait until we get the OTA update that comes before lollipop? It seems from what others are saying, the OTA update brings the BIOS and such up to speed so it can receive lollipop. Am I correct in my understanding?
[Android Q&A, Help & Troubleshooting] jazzespresso:
I believe this is OTA update (update.zip). In order to get this one flashed, you need to be latest official lenovo firmware, not rooted, pure stock (means no any modification to system file(s), including build.prob..ec).

If you are in this category, just download update.zip above download link, and place to your sd card or intnernal card, and reboot into recovery mode (use some key combination, volume+, power button at the same time, can't not remember now), once you are in recovery mode, select "apply update from external sdcard" and locate update.zip, let it flash. If all goes fine, it should reboot your tablet and you will be on Lollipop.

I am in a different situation because I am still on TABS8_50F_S000143_140929_ROW, I did not take other two (possible three) small/medium size official updates, because I knew some of these updates messes up DPI and some other bugs introduced by Lenovo, that's why I stayed on TABS8_50F_S000143_140929_ROW, plus I have also some custom stuff in system folder, so my tablet pretty much modified heck out it, so if I use above steps, I am 100% sure it will fail.
[Android Q&A, Help & Troubleshooting] fat-lobyte:

[Android Q&A, Help & Troubleshooting] busyinny:
Well I have finally revived my S8-50F after transplants from/to one I got on ebay with a cracked screen. I guess it was not the battery, but the motherboard and on/off button both went bad. That on/off button almost made me throw everything out the window before I realized what it was, but with a little more patience and persistence, I am now running a 'frankie' of the 2, but it runs well. Still a little weary of what caused the m/b to go, but chalking it up to bad luck.

Also after spending a day on this thread, I now have the tab with the bootloader unlocked, a permanent TWRP loaded, upgraded to the latest patch (modifying the update to not update ESP, and droidboot), and rooted.

Special thanks to [MENTION=6112002]balika011[/MENTION] and [MENTION=4821597]social-design-concepts[/MENTION] for their work on getting thus far, and a thank you to everyone else that is contributing with posts here.

My main desktops are packed away as I am making room for a nursery, so unfortunately cannot try to build CM now, however I am more than willing to really beta-test anything out there.

We are close to getting this puppy running a ROM that is of note and hopefully making the strong underlying hardware really shine.

[Android Q&A, Help & Troubleshooting] Minto107:
Did you follow the instructions how to flash firmware through Flash tool and installed correctly all drivers? I bet you didn't. You need original KitKat firmware for LC and back to KitKat fix. Then flash is just easy this is why I'm guessing it's problem with drivers(most common because it's not as easy as in Samsung tablets/phones LG or hTc) make sure you've got lenovos850 1.01 driver(you can get it from a device) and Intel ADB/USB developer drivers. Then you should be fine

[Android Q&A, Help & Troubleshooting] social-design-concepts:
Yeah I have, I manually boot to it for testing things from time to time, it generally happens when the ESP/ partition gets corrupt,

When at that screen press and hold power until the device turns off it should vibrate, press the power button (don't hold just press and release, the screen might flash / flicker for a fraction of a second) , generally I will press volume up and down a couple of times (some times if the uefi - bios is locked up it won't always recognize key press, this some times resolves this), try the three button power on again press and hold volume up and volume down, then press and hold power, once the device vibrates or screen comes on release power but continue to hold volume up and volume down. Hopefully you get a black screen with fastboot starting.

Any windows progress? This tablet would run it well if someone could get it to work, actually it has a huge potential :(
[Android Q&A, Help & Troubleshooting] Minto107:
No-one is playing with it so no progress. There is a guide how to enter bios and now when we have unlocked bootloader it's maybe even possible, but you would need USB hub and compatible keyboard(some works some doesn't, same with hub) and then a pendrive with Windows ISO installed on it(Rufus or Easy2Boot does the job well). I haven't tried it by myself because I don't have a lot of free time to play with my tablet. But proceed with caution. I don't know if there is any coming back if you mess something. It's likely you will brick tablet[emoji14]

The device has non-standard usb controller. We need to patch the linux kernel to be able to boot form the usb.

(We can boot from the usb, but when the kernel (linux and windows kernel too)) loads the driver it switches to device mode.

We need a workaround (hack) to keep it in host mode and mount the needed partitions up.

Its not an easy task, not even on linux, whit opensource drivers.

What about Ubuntu on the tab? I'm really into SDR's (Software Defined Radios) ( http://www.rtl-sdr.com/about-rtl-sdr/ ) and Ubuntu has support for GNU Radio as far as I'm concerned. Both Ubuntu and Android are Linux based, correct ? So it shouldn't be that hard of a task. Besides, our tablet was supposed to be marketed as a windows tab but then they decided last minute android was the way to go. Finding the drivers for the touchscreen would be fairly easy. The yoga tabs have the same specs and components as the tab s8, so that would be a good place to start looking for software and drivers.

I would just really really like a new Android. Ubuntu and Windows are for desktops, Android is so far the best operating system for touch screens. What are you going to do, use a laggy Unity interface with unoptimized GNOME-Programs?

Just received a brand new S8-50F.

Android 4.4.2.

Still factory sealed.

As I could not find a dedicated section of XDA for this device, I'm asking for advice.

What would you recommend to get the best out of this tablet. I hear that it comes prerooted - with some sort of unwelcome spy software from factory ('Security HD'). Is this correct?

I also understand that if I do a stock upgrade - it wrecks the unit (DPI or something).

I'm not necessarily interested in rooting the device - just looking for opinions and suggestions/experience.

If you received this - what might be the best thing to do with it?
[Android Q&A, Help & Troubleshooting] Shump:
I would upgrade to Lollipop. You can reset the DPI to 240 by following the instructions here http://xdaforums.com/showpost.php?p=63607892&postcount=962

One of the biggest pros of rooting is to remove bloatware. After removing a bunch of the preinstalled apps I got a noticeable improvement in battery life.
[Android Q&A, Help & Troubleshooting] Minto107:
It doesn't come prerooted at least not from Lenovo Poland(this is where I got my tablet from) also Security HD isn't a Spyware. It's just like any other android antivirus. Completely unuseful ;) yeah taking any updates will change your DPI down to 320(stock is 240) but I like lollipop more than kitkat because of material design and better overall performance(very good gaming, a bit slower UI) but it depends only on your own ;) I hated Lollipop at the very first days but now maybe I don't love it but... It's not as bad as Ive been thinking ;)
[Android Q&A, Help & Troubleshooting] Capt Morpheous:
I really appreciate the input. I am new to this device - so I hope its okay to ask for short-cuts from long term owners.

Can I ask - the DPI issue - did lenovo just simply abandon this issue? Was there no official fix provided at all? Is this not fundamentally ripping of your customers?

Secondly - if I decide not to root (most likely) - is this device likely to get marshmallow?

If you are willing - would you be willing to send me some up to date links regarding topics about this device - I actually won it from work. But I don't want to end up with problems - as so many others seem to have done. For me this is a fresh new unit - and I am starting my journey with it now (even though it is an older unit).

Once again, my sincere appreciation to any that can offer advice and opinion.
