CWM backup

Hello,

files are on their way.

I once used Nadroid online backup and another backup was done with CWM using PC, IntelAndroid-FBRL-01-17-2015, correct ADB driver, empty SD card (prepared with folders and backup file)

and the procedure is/was as follows from kainxss:

***************************************************************************

you do not need to try to run everything in cwm, you need to focus on backup and restore

you will need an sdcard though, copy the backup you have to the sdcard and you have to set it up like this

the format is

root directory -> clockworkmod -> (filename with backup date) -> the files(ie . system.ext4.tar)

example

SDCARD\clockworkmod\backup\2015-04-22.15.45.17\(FILES GO HERE)

put sdcard in tablet

make sure your have a 50% charge at least then go into cwm as before

when you boot into cwm you should have the options

reboot system now

install zip

wipedata/factory reset

wipe cache partition

backup and restore

mounts and storage

advanced

go to

backup and restore

then go to

restore from external sdcard

then choose restore (will show the date you put above)

then go to yes

cwm should check the md5 signature then start restoring

this will take a long time, let it finish (hopefully it starts -_-)

after restoring reboot without rooting and see if the tablet boots correctly

also make sure you remove the data.ext4.tar you uploaded to google drive, if its not from a fresh install you don't wanna upload the data.

*********************************************************************************************

This is all what I did......and still doing, after and after. Flashing ends with success in cwm, it shows the right version in KitKat, but in droidboot the last flashed device name (F or LC) remain.

Now I am looking and comparing the xml files and the other directories of S8-50LC and S8-50F firmware files, provided to use them in/with Phone Flash Tool. There, the flashing result is 100% correct.

Thanks again for doing this great job, and forgive me for asking toooooo much.

CWM backup

Nandroid online backup
[Android Q&A, Help & Troubleshooting] jazzespresso:
OK, now tell me what's your current device status? Are you on S8-50LC or you are on S8-50F?

another thing, if you look at one of your screenshot, CWM flash shows Status 7, this always means system integrity check failed, means there's some system fails edited or changed or modified (like build.prob, etc).

it seems like you are doing many different ways, this also confusing too..you may hard brick your device, so be careful.

If I remember correctly, your device original is S8-50L (without C, at the end), correct?
[Android Q&A, Help & Troubleshooting] Maheshwara:
Do you still need my nandroid of L version? If yes, can I simply delete the data parts or is this troublesome because of md5 checksum?
[Android Q&A, Help & Troubleshooting] kandalph:
step by step

Now at the moment it is both S8-50LC droidboot and KitKat

Updated as well.

Original device name is without C S8-50L.

Maheshwara may provide ‘L‘ firmware. Please see last post.

Would be great ......
[Android Q&A, Help & Troubleshooting] jazzespresso:
that would come handy for [MENTION=6563151]kandalph[/MENTION], if you can able to have full firmware of L, that's even better...if not, yeah upload your nandroid backup somewhere we can download
[Android Q&A, Help & Troubleshooting] Maheshwara:
I only have nandroid. How can I create a full backup flashable with Phone Flash Tool? I think, nothing else than that will help [MENTION=6563151]kandalph[/MENTION], as he has already told that reflashing nandroid L version die not bring satisfactory result...

BTW:

I am thinking about changing to Lenovo Yoga 2 8'' because of its much better battery life. Anayway, same inside both tabs as far as I know... Battery life of S8-50 is so poor and fully charging takes very long... Would you advice me to change?
[Android Q&A, Help & Troubleshooting] lukpol:
Veni, vidi, vici!

I finally solved the blinking issue when watching videos on S8-50 with minimal brightness.!

All you need is to disable HW overlays.

The problem is that in KK version HW overlays doesnt work because when you disabled it in developer option, it will be unchecked when you will go to settings again so it doesnt work in KK.

I heard it work on LP but the problem is that mine tablet on LP sounds like a crap.

So what I did? I rooted my tablet and installed https://play.google.com/store/apps/details?id=com.intangibleobject.securesettings.plugin&hl=en_US. It has the option to disable HW overlays.

The problem is im using a 7-day trial so very likely it wil stop disabling HW overlays when trial expires.

XDA folks, how to disable HW overlays on a rooted s8-50 using a bulid.prop editior?

All those things already happened, if you'd use search I bet you'd find an accurate answer on how to resolve your issue. I'd help myself but I dont use S8-50 for more than a year(its just laying around as backup if my Tab A would refuse to work) so I would make few mistakes here and there instead of helping, but if you can pinpoint to me what happened before you got there and you've actually tried to do and what failed I think I can at least point you in the right direction.

[Android Q&A, Help & Troubleshooting] Brianakin:
I should have known better...

I have combed this thread for days figuring out how to get my S8-50F booting and finally did with KitKat firmware. Then what did I do? I ran the S8 Unlocker on top of it which I eventually realized is only meant for LP!!!!!! So I fear I have a completely bricked tablet. I can hold the 3 buttons down to get to fastboot mode, but no matter what I try to flash with the Intel Phone Flash tool, it wants to reboot and that only gets me a bunch of gibberish (below). But does anyone know if it's possible to flash something in fastboot mode that can fix my bootloader (I assume it's the bootloader that is doing this)? Or some other "back door" process that can unwind what the S8unlocker did to it?

Thanks in advance.

The hardware in this tablet is top notch. Up to this day I am baffled how fast I can briwse and play games and videos on it. Unbelievable that noone has rooted/customized the rom.

I hope we'll still be able to use this device for the next 2 to 5 years on Android 4.4.2...at least for browsing the internet. (if not then we can always use them as spare readers, portable video playback & retro gaming devices).

Android market share in 2019 shows Kitkat holding on at close to 7%. >> https://www.androidauthority.com/android-version-distribution-748439/

I've been using my Tab S8 nearly daily for the last 4 years; still runs perfectly, plus I just replaced the battery yesterday; been rooted and kept on early firmware S000146_141010....and was lucky to grab another broken one which I repaired and kept it around as a spare (lucky it was also on last Andr4.4.2 firmware S000200_150121; also rooted and changed the dpi to 240 to have that great look.).

Amazing old tech with no problems at browsing the internet, viewing videos, and playing some games.

I wouldn't do this but...If you really need another year of support from apps with this tablet, you could always upgrade the tablet manually to Andr 5.01 (from the front page firmware roms).
