How to backup firmware

I need some advice how to backup stock firmware on this tablet. With or without root, doesn't matter.

Can it be done only on tablet or/and does it need a connection to PC eg win7?

It would be nice to hearing from you with some 'how-to'.

Lollipop 5.0.1 problems?

Any problems running 5.0.1 lollipop? Or we are better off to wait for 5.1?
[Android Q&A, Help & Troubleshooting] WildVenom:
Great! We can finally have some Lollipop goodness!

Those who have managed to get the 5.0.1 Lollipop update running, please comment based on your experience with it.

1. Is it totally stock Android? I mean no skinning and all? :D

2. Are the system Lenovo Apps updated? I mean apps like Mail, Calendar, ContactManager (Contact/Message/Dialer), Gallery, Video etc. are they updated to a newer version or have they been replaced by AOSP counterparts?

3. Battery life and performance seems to be improved over KK. Your comments. :fingers-crossed:

4. I think this will be the last update this tablet receives officially from Lenovo. The newest version as of now is 5.1.1 and we will be seeing 5.2 soon. I have read that 5.0.1 has many issues (bugs, memory leaks, no silent mode etc.). What critical improvements/features is 5.0.1 missing that 5.1.1 has? Improvements/features that can't be added by an Xposed module/Root app (something like improvements to ART).

So does 5.0.1 have some shortcomings that I should be worried/bugged about?

Lenovo S8-50L ---> Lenovo S8-50LC, get voice call support

Hello,

I own the Lenovo S8-50L, with LTE, but no voice call support. I was told that it might be possible to flash the tablet with the ROM for LC-modell, and get the voice call support.

Is it necessary to root the tablet first, and how do I flash the LC-ROM? Thanks for any information.

Successful restore to S8-50L

@jazzespresso; kainxss, community

After many hours, sleepless nights, testing, flashing, reading, over and over, with your help, I was able to restore the tablet back to S8-50L

You're all doing your best, investing lots of time, only for one thing!!!! In helping people. This is what I've found out. Thank you all.

Or like Hancock would say

GOOD JOOOOOOB
[Android Q&A, Help & Troubleshooting] KainXSS:
I will try to give some answers but I installed via cwm so its not a complete install, I still can't install the bios so I am only installing the system and boot

Its nearly a completely stock android for intel with a little bit of lenovo theming

some of the lenovo apps in kitkat have been removed in favour of the lollipop apps, still no multiwindow support, launcher is the stock lollipop launcher

high hopes will have to tell you about battery life as I have the -1% error and can't test it, performance is a little better

it will probably not be the last update so I would not worry about that

I have heard though that after the lollipop update on some lenovo devices, its a one way trip, previous versions won't install, but I cannot confirm it myself, high hopes had this problem I think. So it might be wise to wait instead for it to be released officially, lenovo has already said it will release lollipop for the S8-50F in may.

this will probably change by the time its released for everyone though, it does feel a little bare and I'm really thinking the ota between kitkat and lollipop had extra data or something(we don't have it)

back to kitkat for now :)

Thanks for the info, It's nice to Lenovo actually moving forward with this tab. They still haven't rectified the HORRENDOUS fm radio icon though. So stupidly low res it hurts to look at it. I wasn't sure if it was just me or if it was a thing for everyone. any way to replace that icon with something a little more attractive? not a deal breaker if there isn't.
[Android Q&A, Help & Troubleshooting] sirxdroid:
Yes mine reboots too while charging, though I don't know at what % it happens.

Plus wifi stops working sometimes, can't even toggle wifi on/off anymore. Only a reboot fixes it.

Add to all that the poor battery life and this tablet is a disappointment. Lenovo support is useless as we've come to expect from the big hardware makers.

I have wifi version of S8 tablet and after upgrading to android 5 Lollipop the audio is strange. It is hard to explain but it is not what it used to be.

Before I throw it out of window I would like to try downgrade but i got a error during downgrade.

When i use intel flash tool 4.4.2 and firmware from first post, after hitting "start to flash button" tablet reboots and I see error on tablet screen:

Intel Platform tools - can not boot to fastboot

Hi guys,

I have found a LC rom. So I tried to restore this using the Intel tools. But I am not even able to enter the fastboot mode (volume down + power). The only way I am able to boot to a screen that shows something is volume down + up + power. Then there is starting fast boot. Nothing else.

Hi, I have bricked my Lenovo Tab S8-50LC. This has happened before also but i had managed to get it back, but now i am not able to. I am able to get till TWRP though, dont ask how :D, but could someone be kind enough to upload a TWRP backup of system and boot please ? I tried flashing the rom from twrp and that also fails, although im gonna try today again. It says something as binary failed or so , i cant recall exactly. could anyone please please please upload a twrp backup of System and Boot. My model is Lenovo Tab S8-50LC. Many thanks in advance
[Android Q&A, Help & Troubleshooting] Minto107:
Easiest way to get it back is reflashing it via Intel Flash Tool. Also you can't flash any rom made for LC as recovery shows your device as S8-50F. About backup. I would be able to do this as I own S8-50L with LC software on latest lollipop but I don't have TWRP installed as its just reflashed and I don't have access to my pc now
[Android Q&A, Help & Troubleshooting] abhijeet715:
Hi, Mine is an LC model only. I tried reflashing the LC rom itself for the tab but couldnt do. I have the full KitKat ROM, but i guess the Lollipop is the OTA. I downloaded the rom from another website (repairmyphone) for LC and tried flashing, but it gets stuck at some modem error. I trued flashing kitkat also, still no use. I tried tools like s8 unlocker and bios repair, but nothing happens. So i am totally confused, as to what is to be done, and i thought the best way out would be a TWRP backup. Can you tell me whether this recovery is for S8-50L or LC ? And any way out for the same, or a link to the proper lollipop rom for LC please ? Tia

All this crap happened just due to a clear cache which i did through stock recovery, which got screwed and couldnt mount cache.. tried everything, even flashing the rom from the stock recovery but nothing happened.

Tablet doesn't go to sleep

Hello Guys!

Recently, my tablet has been draining battery at an insane rate, I went from 84% to 49% in just a single night!

I checked it out with BetterBatteryStats, (logs attached), and it seems that the Device just *never* goes to sleep!

In the logs, you can see "Deep Sleep 0%" and "Awake (Screen Off) 91,5%".

Please don't tell me "Lenovo is so stupid", because this used to work just fine a few weeks ago.

The most wakelocks come from Google Play Services:

ContextManagerWakeLock (Google Play-Dienste): 46 s Count:11972 0,1%
*net_scheduler* (Google Play-Dienste): 8 s Count:12093 0,0%

Does anyone have an Idea how to fix this?

Here are the android stats, mostly useless. All they tell me is that "Android OS" and screen used all that power, which is just a lie.
