Hello, I have a problem with my S8-50f tab. Yesterday I got a notification of new OTA update and I did it. The tablet was rooted before that and now it can't turn on the system!? I have recovery and fast boot but I can't connect it to the PC because some driver is always missing. I've tried everything and on two PC's. Is there any option to install ROM via SD card?

This is where I'm stuck.

I presume that I'm in bootloop because of root. Can someone direct me to the solution please?

You should restore stock rom from twrp backup (boot, recovery, system - nothing more).

See here

http://xdaforums.com/showpost.php?p=65696821&postcount=1904

Do you own backup first (boot, recovery f.e) then replace files with downloaded.

[Android Q&A, Help & Troubleshooting] mac231us:
Success?

after several failed attempts (tab sitting in Lenovo Android screen despite factory resets stock recovery flashing etc etc) I started from scratch...went back to KK...updated in KK then to LL then to the latest LL update (all standard ota Lenovo updates through wifi)

now am in temp TWRP as well making backup

not sure if S8 unlocker works if I want to go back to KK but have got this far (no issues)

not tried the SIm to see if response has improved or not in as cannot find the nano to micro adapter (lol-had it just until Sunday p.m-somewhere around)

see lot of google apps now installed-all of which I usually remove except gmail and maps

will try to root it soon and report back

EDIT...flashed beta 2.62 SU zip from chainfire...tested with rootexplorer...have root!

OK, somehow I've managed to activate temporary TWRP and downloading TWRP_BACKUPS_S8-50F_S000456_151016_ROW.7z as instructed, what's that about boot, recovery, system? It's totally different than my other devices. I don't install the whole ROM but only those 3 files? And why do I backup my own device, it's not working. Is it just in case or do I need that backup to end reinstall process?

If it is easier to do full reinstall without these separate restores an backup I'd rather do that way?
[Android Q&A, Help & Troubleshooting] dzidexx:
Your own backup is for generate folder on sdcard: twrp/backup/baytrail/date...

Delete yours, paste all files. Restore only boot, recovery, system. Wipe dalvik, cache, reboot.

If you restore another partitions you will loose imei, mac, etc.

OK, when I download ROM from page 95 how do I put it on SD card? Like 7zip file or unzip it like a folder?

I've tried both ways with some that I downloaded from some other site earlier and TWRP doesn't see them!? Only sees my backup. I go on Restore, yes? No on Install in TWRP?

Yes, you should unpack it to sdcard (rar,zip,7zip): /twrp/backups/baytrail.../anynumber08_08_2016.

In empty place - first delete yours backup files.
[Android Q&A, Help & Troubleshooting] milkobgd:
OK, if I read you right I did backup only to make backup folder (with my backup files) than I delete all those files and copy the files from unziped ROM from page 95. Then I restore only boot, recovery and system from that folder that I made?

HOW TO REPAIR YOUR TABLET AFTER BOOTLOOP CAUSED BY OTA UPDATE ON A ROOTED DEVICE FOR NOOBS (like me)

First, you need these files

IntelAndroid-FBRL-7-24-2015

for installing temporary TWRP and

TWRP_BACKUPS_S8-50F_S000456_151016_ROW.7z

(TWRP backup of full LP ROM for S8-50F WIFI version only, for LTE version you need to find LTE ROM backup). You unzip the file and that unziped folder copy on (external) SD card and insert it in a tablet.

And the biggest problem are PC drivers 'cause they, especially MTP driver are problem to make them work. I presume that the problem is in incompatibility with some other older drivers that you have on your PC from before. For that cleaning you can use program,

Usbdeview (free app).

Then you install the drivers. I've tried so many that I don't know which exactly did I use.

After that, my tablet managed to contact with the PC.

Connect tab to PC in bootloader mode (vol down + power).

Then you install temporary TWRP. My choice was 4. and then T4.

When temporary TWRP is on you MUST do a backup of your ROM. Only reason is that TWRP make backup folder with files of your ROM. You then delete all of those files cause you don't need them. You only need empty folder. You are using TWRP file manager of course. Than you copy all the files, one by one, from downloaded ROM from external sd card in the folder that you made in internal memory (by backuping yor ROM earlier).

Then you choose RESTORE from TWRP main menu and choose what to restore.

You restore ONLY BOOT, RECOVERY and SYSTEM!

After restore choose Wipe - advanced wipe from TWRP main menu and choose to wipe dalvik and cache. After that you choose reboot and your tablet is alive again.

Once again to mac231us, lublin and especially dzidexx, thank you very much.

So... is the speaker audio fixed in the new OTA?

[Android Q&A, Help & Troubleshooting] Minto107:
Well written guide, good job man ;) but I making backup is not necessary I will tell you 3 other ways you can get the necessary folder where you place working backup :

1/In Temporary recovery installer it shows the serial number of your device. It's easy to find. It always starts with BayTrailXXXXXXXX(where X is your serial number, BayTrail is probably most of you know, the codename of Z3XXX series Intel CPUs)

2/being in droidboot. There should be serial number at top of it(somewhere below normal boot text) it also stars with BayTrail so you'll find that easily

3/In temporary recovery you can start backup of small partition(like recovery or config) or even cancel doing backup after 3 or 4 secs and BayTrail folder will be created and then just simply copy backup there and reboot your tablet into recovery again

These are just other possibilities but your one is of course correct and much simpler than mine ;)

[Android Q&A, Help & Troubleshooting] J0s3f:
How big is the new OTA? I am back on KK so I can't see the size in the updater. I had too many problems with LP before. If it is a large update (hundreds of MB) I might try it. If it is just a few MB I don't think the system will feel much better and it is only some security fixes and small bugfix.
[Android Q&A, Help & Troubleshooting] dzidexx:
If you are on KK you have to install all updates for LP. 1st - 1gb, 2nd(last) - 30mb.

I have downgraded to KK, and now I am repeating upgrade to 5.0.1, and then to new OTA. I will try to root and do some testing.

Which tests should I do? Do you guys want to know something in particular?

Please no "is sound like before" or "does battery last 7 years like before" because I don't know how it was before, i bought it on LP.

Also, I don't understand how you could ever like KitKat over Lollipop. Seems like stone age to me, and Lenovo tried a bit too hard to make it look like an iPad. I don't like apple ;)

You can restore stock recovery in twrp (you own or from others). The Droidboot - I think is the same.

Ps

I don't see anything special in this ota. If you want I can upload the /Vendor folder (dolby) or full twrp backup s8-50f.

S8-50LC users:

I did(probably, finally) working OTA update zip for S8-50LC S000456 firmware to work on S8-50F recovery(by Balika011.me or SDC). I would try it by myself but I'm back on KitKat now and I have got relocked bootloader but if flashing OTA zip provided by SDC worked for S8-50F users it should work on your S8-50LC without any problems. Of course it features verification free updating(users with root should be able to update without any problems with bootloops) and droidboot free(as it's same as in S000456 as many users reported). Here's the link:

https://drive.google.com/file/d/0B1rqpiMcpORZRHhjUkt0YWMzVlU/view?usp=docslist_api

Enjoy ;) feedback highly appreciated :D

One note: It should work because it uses S8-50F binary so if TWRP passed on S8-50f it should on LC too ;)

I don't think anyone has tried. But you can be the first! ;) If the only change you made is the root binary, i think it will work.

[Android Q&A, Help & Troubleshooting] Settler11:
Just today there was an 25MB update for the S8-50F. But I don't see any improvements.. As a matter of fact, I experience worse WiFi then before so I suggest to not update it. I'm going to try if I can get back to KK because L kinda sucks on this. (slower, battery, wifi, lag etc.)
[Android Q&A, Help & Troubleshooting] fat-lobyte:
Yes. Note that a lot of people complain about Lollipop, that it's slow, worse battery, worse sound... Look at post above mine.

For me, Lollipop is fine, not slow, battery is OK. Be sure to do a factory reset after updating and you should be fine.

Yes, but I think if you have changes to /system, like XPosed or AdAway or removed system apps, then your upgrade process might fail and you get boot loop. To be safe, revert to stock, do a full round of OTA updates and finally root again.

Yes.

Officially, only OTA updates and no flashing. Unofficially, some users have provided TWRP recovery of fully updated Lollipop that you can flash.
[Nexus Player General] jaykresge:
I'll maintain this thread so long as there's interest. In order for an emulator to be listed here, it needs to meet the following criteria

-must be able to open the app with the OFFICIAL Nexus Player gamepad (NPGP)

-must be able to exit the app with the official NPGP

-Must be able to configure all in-app options, to include gamepad button assignments, with the NPGP.

-Must be installable from the Nexus Player (waivable if installable from Play Store on PC)

-Must have a leanback launcher shortcut

Basically, if the emulator requires root, ADB, third party peripherals (for use or configuration), sideloading, etc., it won't be on this list.

NES:

NES.emu ($3.99)

Open the Play Store on your Nexus Player, and scroll up to search. Type or speak "Nintendo" or "emulator" and this will be one of the options that comes up. Alternatively, you can purchased and push install from the web-based Play Store. Open installation and first run, you should go to the settings and configure the gamepad for in-game actions (specifically, to exit the app).

SNES:

Snes9x EX+ (FREE)

Same as above (same developer and menu system).

I'd advise using the SNES emu first (as it's free) to learn how his menu/control setup works, then move on to his other paid emulators. You can see his other emulators at this page here - https://play.google.com/store/apps/developer?id=Robert Broglia&hl=en

Alternatively, you can open the Play Store on the Nexus Player, scroll up to search, and type/speak "emulator." Pretty much all of those are his. As I purchase his other emulators I'll add them to the above list when confirmed. If others wants to try them and report back, I'll also update the list based on that. If you find other emulators that meet the above criteria, please share.
[Nexus Player General] Magnesus:
Won't they get removed from the store soon? Emulators are banned quickly on Google Play, aren't they?
[Nexus Player General] jaykresge:
Most emulators on Google Play have been there for years. Nesoid and the other emulators made by that developer were removed for a specific violation. Here's a good article on the subject.

http://www.androidpolice.com/2011/0...nded-are-emulators-soon-to-be-banned-content/

Also, I'm going to go out on limb here. It's normally bad form to distribute links of ROM distribution website (and I won't post it here unless a moderator explicitly tells me that it's ok). However, there's one website that is actually legal (and as such, don't expect to find the best games here). Basically, the ESA has set up a way of protecting the rights of gaming companies and their work, while also offering some ROMs to gamers. Read more on the ESA here:

http://www.theesa.com/ (NOTE: Not a ROM distribution site)

Due to this, one website is completely ESA compliant and has, at the request of Nintendo (and other parties) intentionally set up dead links that will usually be at or near the top of Google results. If you search for a specific ROM on a Nintendo platform, and you click on the link for this specific website, all you get is a link that says "This page has been removed due to copyrights." What few ROMs are available on this website are legally freely distributed. Have at it.
[Nexus Player General] Mi|enko:
The only problem I have with console emulators has always been the controller lag. This has been true even on my gaming PCs. Playing Super Mario 3 for example, on my SNES (bought one just for this game - lol) it's smooth and does what I expect it to. On my PCs, ADT-1, etc., there's always a minor lag that's just enough to throw timing off.

Mame for the most part on the PC has worked very well for fighting games. Chankast with MvsC2 was damn smooth for me. I'd love to see Android get to this level of emulation.
