Thanks for the broken link info. It is now corrected and working fine. As for CWM/TWRP backups, I didn't have problem in the past, at least when on KK. A CWM backup I made ages ago, worked numerous times for me and for another member here that used it. I'll keep that in mind though for future actions!

After updating bootloader it's recommended to rebuild recovery to base it on new lollipop UEFI(my own experiences on gs3 android 4.1 vs 4.4.4)

PS. TWRP is better on our S8-50x so it would be very nice if you could do backups with TWRP format ;)

There's no lag in UI and YouTube for S8-50F, did you reset factory settings when you updated? that usually makes things somewhat smoother after a mayor Android upgrade.

Downgrading will be pretty hard because the lollipop update updates both UEFI and changes the UEFI to 64 bit.

I don't know if could help someone but I can't update my lenovo tab s8-50L with OTA update trough the lenovo system. I just download the zip posted a few page back (that one about 1,1 GB), put it in the tablet and then reboot in the droidboot mode, something like fastboot (with device off press power button+volume down). From there reboot in the recovery and here select install zip from internal storage, choose the zip you copied, et voilà: Lollipop here.

The only problem is the Root. I can't root the tablet with all the method reported in this thread, Windows 10 don't recognize fastboot driver.

[Android Q&A, Help & Troubleshooting] RaawrItsTomi:
Here's what I found about the lollipop update so far

1. The performance is stunning, everything is buttery smooth

2. The camera quality might have decreased a bit (???)

3. The battery life is amazing. I've been on stand by with WiFi off for like a week and it only went down like 15%. Overall battery life has improved a lot on my device.

4. Dolby sounds weird

5. Some really weird bugs (screen flashing into stripes then bootlooping until it finally boots)

6. Wtf is that FM radio player UI

BTW I updated on a factory resetted kit kat and did a factory reset on lollipop as well. So if you have any problems except for Dolby you should try that.

Edit: This is 5.0.1 Lollipop (S8-50F_S000456_151016_ROW) on S8-50F

[Android Q&A, Help & Troubleshooting] Shump:
1. Yes, you can root Lollipop http://xdaforums.com/android/development/intel-android-devices-root-temp-cwm-t2975096 T4

2. I used the system update.

3. I have no issues with my S8-50F. Lollipop is alot faster, less drain at idle, and about the same battery life for my usage. ( 5-6 hours of screen on streaming HD videos and browsing the Web)

It took a few charge cycled before the battery stabilized. So if yours isn't lasting long at first hold on for a couple of days and it should sort itself out.

Don't use xposed until some1 will provide backup. So far no-one was able to boot xposed+it caused device to crash and no longer booting to OS

It means that Android Kernel is draining battery whole time when device is in sleep mode(it keeps cores running) but for now it's app fault. It keeps device asleep only for 3 mins during 3hrs. So it's not that bad, but my S3+ 4.4.4 in same time about 1.5min
