it's actually probably how mine is generated, i wrote a script for patching the stock recovery to convert it into a twrp recovery, let me clean it up and remove the parts related to installing the insecure efilinux.efi bootloader, and i'll upload. i wrote it so that intel devices that can boot unsigned standard aosp boot.img format could generate a permenent recovery for their device from the tethered recovery.

Can someone help me with my S8-50F?

At first I was unable to get Lollipop on it because of 12MB failure update. Then I flashed firmware using version for LTE. I don't like Lollipop on this device a lot (battery life on stand-by flies away too fast, UI, overall xp)

So I want to rollback to Kit-Kat. But now it just turns off during flashing.

P.S. Yeaah.. so lollipop is quite crappy for S8-50F version. Kit-kat look way better. Too bad I spent too much time for these updates\rollbacks.
[Android Q&A, Help & Troubleshooting] Minto107:
Lollipop can work smooth and fast. Also it provides better performance than KitKat(in games) the only thing I couldnt fix so far is of course the battery drain. Hope someone will find a way to fix it ;)

once you get there you can connect and do s8 unlocker...then the bios repair through latest flash tool then do the kk install with the modified xml scatter

To receive updates you need to set a region code. Setting it is like installing CSC on your Samsung phone it also enables some country specific options ;)

Setting it depends on your tablet version. TBS I don't remember the code and I'm at school so ;)

UPDATE: Brightness Fluctuation/ Screen Dim Issue Fix

OK, a little feedback on this. It seemed strange to me when another member said that it didn't work for him while I wasn't facing the issue anymore, which I did before and was annoying. Since I had more apps freezed, I made a thorough investigation and tried to unfreeze them one by one, while seeing a video through chrome (trial and error). It turned out to be that com.intel.security.service wasn't the one that was solving the issue.

Believe it or not, there are 2 system apps that needs to be frozen in order for not having the brightness fluctuation issue. These 2 are Insertwallpaper and SetupWizardBrowser.

Both must be freezed!!!

And trust me you won't have the issue anymore nor this action will give you troubles of any kind.

Sorry for previous false feedback but I am persistant and

this time the info is correct

. And actually these are the only 2 apps I have freezed at the moment so I don't see a reason why it won't work for you. You may reboot after doing this but it is not necessary.

Peace! :good:

Use the newest version of PFT - The 1st page of this thread.
[Android Q&A, Help & Troubleshooting] mikib1:
"Boot failed: EFI Hard drive "

To recover from this problem and revert buck to KitKat I just made 3 steps

1. Put the tablet to fastboot mode (vol + and - , power on)

2. flash repair Bios.rar (first unrar) via PTF

3. flash KK rom (but first replace the file in the directory of rom you are going to push in to the tablet from rar. named "TABS 8-50 Otkat.rar")

All is explained in the russian forum and all the files that are need to do this, are there.

Read all the warning posted up for this specific case, at some point you cannot bracke working program, because you can kill your device.

Sory if I post this, if that was made somewhere earlier in the forum, but I searched two days and I do not found any simple information how to do it.

Sory for my English...

Currently im using other display settings and reccomand not to mess around with config files etc. Highly reccomand not too mess in config files, just becouse it works perfect on external program + root.

Just Root and use NOMone Resolution Changer from Play Store.

Fastest way to see differance in speed and detail is using Seascape from P.Store . Its about 4mb nice sea water movement simulation.

It shows clearely that on highest detail settings it gains 10fps more in 1450x900 vs native res. On native its choppy ~15 fps, while in 1450x900 is fluid ~25 fps. Thats why.

I also haved restarts with no native resolutions and its zero problems with loading system, even if crash of some kind ( not caused by res changing program, but overall auto restart or hang up. buggy aps caused , etc )

So now i set new awesome working res that make me screen almost precise as native bit it still five huge fps buff. Lets say for examplemWot Blitz.

That new res settings i use in NOMone program is Width 900 , Height 1450 Dpi 200. Its way more precise than 1280x800. Almost feel like fullhd.

Icons are small, everything is great .

For example , Wot Blitz in those settings runs constant minimum 30 fps on worst conditions and mayhem , on ALL settings set to maxiumum possible, while on native display 1920x you have just little more precise ( noticable from only up close ) BUT fps drops are often to 20 on worst ocasion. Even less.

It seem on average 10-15 fps gain , and resolution is perfect. Its very sharp, hard to notice real differance in daily use.

So i think its now stupid to not use that program. I will never-ever stop using it , and Full Hd in gaming is just stupidity if you cant have fps you want just becouse of ridiculousely sharp screen in game on just 8' screen. For gamers fps are most important thing . Fluidness is all, resolution is extremely fps hungry.

Guys, what about AWFULL SPEAKERS SOUND AFTER 5.0.1 ? Any change, hope, new solution etc ?? :(

[Android Q&A, Help & Troubleshooting] szczesny:
I had problem with proper connection on Win 7. To resolve it :

First of all, you must install those Intel drivers for pc conmecting your tab. It is Intels specialized Atoms driver. Its main program plus pre program for that driver. Its here on forum, you must search.

And second, always have usb debugging mode ON in programmers settings in S8.

Android Terminal Emulator's strange behavior in Lollipop.

Hi all!

I recently upgraded my tablet to lollipop and while it's been fine for the most part I have noticed a strange issue with the terminal emulator behaving strange. The cursor has an offset of a few spaces which seems to get larger as you type. This wasn't there in the kitkat version. I know it's probably a strange that I use the terminal emulator at all but I have a bunch of bash/python scripts that I use for a bunch of stuff and the terminal misbehaving is annoying. Any one else see this issue?

Termux runs well.

Hi! I came across this app called Termux and I can confirm it runs well on this tablet. It's actually really really cool. Not only is it a fine terminal emulator, it's also a debian like environment with apt pre-loaded so you can install other packages, they even have a dedicated repo with common software compiled against bionic. Earlier I used to basically use a bash alias to execute python from ubuntu by passing it as an argument to ld.so but since Termux's repo has python3 I can finally use my scripts as easily as I can on my computer. The repos even have gcc/g++ but I can't say how well that works(plus I can only imagine how painfully slow compiling C code would be on an atom chip). It's amazing, give it a try.

Hey guys, asking here since this seems to be the best 'repository' of knowledge for the S8-50F.

My tab went dead overnight and will not start up at all. I think it has something to do with battery and it getting so drained that it apparently will not charge, or something to that extent. This had happened a year ago, when I had it only for a month, and I got it fixed by doing something simple but I do not remember how. Have read about trying to keep the power button pressed for 20 seconds while on the original cable and adapter, but cannot find the original adapter, and not sure which is the original cable (does this really matter)? Have tried with other 1.35A or 2A adapters.

S8-50F on L, rooted if that matters.

Any feedback would be greatly appreciated.

my last suggestion is to disconnect the battery, leave it unhooked over night the press the power button to make sure the boards discharged then reconnect the battery and try the three button power on again, my tab was unresponsive a few times when i was playing with alternative bootloaders an this always brought it back.
