I messed up somewhere.....I had Lollipop rooted, tried to update ota and it failed......Thought it would be better to reflash lollipop and start over,,,,,I flashed it, and then it booted into a blue and white setup screen, in which I proceeded to use default settings (figured that would be best) and bam! bricked......But yes fastboot black screen is my only option at the moment

[Android Q&A, Help & Troubleshooting] Minto107:
That's a bad news. I've wanted back to otkat zip because I've messed something with my lollipop and I couldn't update to latest one but now I'm so happy that I have perm recovery and just restored old system and works correctly. Russian ****s on rules. They stole everything what they can from xda, this is unacceptable but now it can be useful(having that stuff might be helpful for some) so it's good that they are keeping that stuff. About those yoga guys, if they posted some method on XDA and now they deleted it they lost already. Xda is often cached and it's very likely that this stuff is in some cache available somewhere on the web

Can you post full name of the zip you've tried to flash? It needs to be x86 and SDK 21. Also verification means that you've got signature verification turned on in TWRP settings(you can disable it from settings menu in TWRP)

Don't worry. SDC is just very busy. Be patient. If lenovo-forums.ru would get back to life it would be really easy to fix

You have the wrong Zip!

Our device has an Intel processor, not an ARM processor.

It should be xposed-v80-sdk21-x86.zip, not "sdk22" instad of "sdk21" or "arm" instead of "x86"

You need x86 (for Intel) and SDK Level 21 (for Lollipop).

Finally got it flashed.....now I'm caught in a boot loop.........UPDATE!! Nevermind it booted, and it works!!! Thanks for your time, I appreciate it
[Android Q&A, Help & Troubleshooting] fat-lobyte:
Which Lollipop? You mean from users here? Because there is no official version.

Also note that you need a newer version of the Flash Tool, the old one had a bug. For example, I have Intel Platform Flash Tool version 5.4.2.

Officially, you need to flash stock KitKat, then do 4 OTA updates until you are at lollipop. This is the link from the first post: https://www.androidfilehost.com/?fid=95855108297851228

This should definitely work.

You can try again with user-provided TWRP backups, but be sure to use new version of flash tool AND get the correct version of your tablet: F (WiFi) / L (WiFi+ Data) / LC (WiFi+LTE (Voice)
[Android Q&A, Help & Troubleshooting] Minto107:

First impressions about new LP update:

It's very smooth and it's not lagging anymore(what Im kinda suprised :P)

Haven't tried sound but new libs may fixed that

Overall performance in system is very good, apps are loading in a second even youtube

Right now I'm doing factory reset just to have a pure clean experience with new update :) but it takes it some time as I can see but factory reset always takes more time than update but right now it finally booted. Right now root and setting dpi to 240 and I'm ready to go ;)

(Copy both files that are in the otkat folder (pft_flash_lte_normal & FOTA_IA32_R_0002_19_SecEnabled_From_X64) )

Flash away....worked for me...good luck
[Android Q&A, Help & Troubleshooting] Minto107:
It's definitely worth it. If you want to be on LP you just HAVE to take this update it's simply amazing. The only thing is still broken is touch when LTE modem is on but I can live with it ;)

I now confirm that myself. I started all the way from scratch, installing all updates from original KK firmware, then when I finished did a factory reset. Smoother experience overall, didn't have time to check battery but i get the feeling is a tiny bit better if not the same with previous L update. Unfortunately fm radio interface still the same as it came from previous century :p Honestly I wasn't expecting an update, even a small one, from Lenovo anymore. Still such a same this device is so mistreated by Lenovo Team concerning optimization of software for the hardware. This tablet could have easily been a top seller as Nexus 7 gen. 2 was. But Lenovo never show that occuring hence the struggle of the device to perform well.

Anyway, still surprised when I stepped here after so long to find out about the update :silly:

Amazing update, but you dont know if sound is same state as it was in Kitkat? Guys, seriousely , youre joking ? :) Didnt tested update, but it is "amazing " :p

How it can be amazing and still dont know if it repaired sound ? It should be noticed immmiedately.

You told me months before that your speakers also sound strange after 5.0.1

Dont have any lags without this update. All i have is annoying Non stop auto screen dimming to 1/3 and destroyed and distorted sound most time from speakers. At last it fixed constant screen dimming due to " overheating " ?

How that update can be " amazing " ? You said - almostmall repaired. So , what about sound ????? Please check it and tell here.

And im on root , before did 2x backup loading when messed with these stupid Dolbys Atmos or other Vipers audio etc.

Minto. Now, unroot and can load that update without bootloop ? I dont know what i messed up with system. 2x backup, reflashing dolbus etc, root etc.

:confused:

Unable to do system update

I just bought Lenovo S8-50f and as soon as I started it, it asked me to system update which was for around 12MB.
