root newb (very computer and embedded sys savvy though) just need some quick guidence

I've got a bone stock t310, just need a bit of guidance. I just got the kitkat update pushed to me last night but don't want update yet.

I know my way around computers and embedded systems (mechatronics engineer) but I've never flashed a phone or tablet, just micro's.

I see in this thread that the bootloader isn't completely shutdown in the update, and rooting is possible while also keeping the flags set that will allow warranty work if you restore backup or what not.

Question is, where do I start? I see most people have updated to 4.4.2 using ODIN. Is this required to get backups? Should I root before updating and then load the 4.4.2 through ODIN (I guess this keeps the old bootloader?) or can I just update to 4.4.2 and then get root after that?

Just a bit confused on the steps to go through. Probably won't mess with custom ROM's (but it's possible) but I would like to finally have root access while still being able to get warranty service if needed. (parents bought the COSTCO extended warranty so I don't want to kill that possibility)

Like I said, I'm very good with computers, have put together and programmed many micro's, but they have all been flashed with my own code and a BDM pod so there was never any chance of me killing anything.

Just looking for some quick guidance if anyone can help. Been browsing the forums, and know how to search so I don't need super step by step instructions (unless some info just can't be found here). Still reading the original root thread, but doesn't look like it's headed towards 4.4.2 stuff.

Any and all help would be greatly appreciated.

Regards,

Steve

What stop working: netflix app on screen control do not work.

Wifi icon appear and desapair, but it is connected. God why I did this upgrade to 4.4.2...damn
[Galaxy Tab 3 General] Smokey Mc Pot:
That is interesting...

Someone else posted in another forum, the exact same problem with the Wi-Fi icon...

Have you done a factory reset yet ???

ps:

To do a factory reset on your device:

Open "Settings" and select "Backup and restore" than backup your device and finally select "Factory Reset".

After that Samsung will let you restore again.

Hopefully that will fix that issue.

Good luck

- Once you root your device, you can say goodbye to your guarantee... well, unless you can find a way to work around that!

My advice to you is to accept the Update first and root the device after.

And also Download a copy of your local new firmware + Odin from Sammobile and keep it saved in your pc, as a backup in case something goes wrong later.

Good luck!

<Solved>

I followed the above, steps 1 & 2.

I booted into KitKat 4.2.2 without any problems. I noticed that all my old apps and data were still on the tablet. I figured, I would like to start fresh by having a clean version of KitKat backed up using twrp. So I booted into twrp and did the following:

1. wipe, advanced wipe. I choose Dalvik Cache, Cache, System, Data & Data and then did the wipe.

2. then I opened "Format Data" and type "yes" to confirm I wanted to proceed.

When I tried to reboot from twrp, it gave me a message saying something like "operating system" missing. But I proceeded anyway. Now the tablet keeps rebooting (the Samsung Galaxy Tab 3 screen comes on, then the Samsung logo with the big blue circle comes on, then the device reboots.)

I've tried several times to reload kitkat using Odin, but my tablet keeps rebooting after the Odin process completes.

Please advise how I can fix this.

thanks.

Edit: ok, I should have read from the first post more closely. All that was required was a hard reset. (Boot using volume up+power. Then navigate to wipe/format data. Then reboot. Wait about 5 minutes for it to boot up.)
[Galaxy Tab 3 General] sylvestor2013:
After flashing cf-auto-root, I do have root access. I then flashed twrp, so I could do a backup of my kitkat system. Upon finishing the backup and exiting twrp, it gave me an option to root my device. I chose not to run that option. When I restarted my tablet, I installed root checker and noticed that my device is still rooted.

I'd prefer to leave twrp recovery installed, so I can restore my tablet at any time. If I don't leave cf-auto-root recovery on the tablet, do I loose any functionality or will it cause me any future problems ?
[Galaxy Tab 3 General] Lakland:
Yes I did factory reset, same issue

[Galaxy Tab 3 General] Iceberg86300:
can revert back to stock after root? let it auto update to xar region 4.4.2 last nigh

Thanks, did some reading and found that odin was just a flashing tool making manual flashes possible.

I just went ahead and let the tab update. It is the XAR version (cellular south? Don't know how they came up with that) kernel is 3.0.31-1897308, UEUNCNF4, built June 17. Using device info the bootloader shows T310UEUNCNF4. Change list is different from any of the XX firmwares. Any info needed on this build just let me know.

Everything seems to be working, but honestly I was hoping for a bit more. Root is on the horizon.

From what I've been reading there is no flag or counter, but that's on the earlier french release.

As of now it's my understanding that if I flash TWRP and make a backup prior to rooting then I can flash that backup of I ever need warranty service.

Is this correct? Or am I missing something? I've read I can unroot. But will flashing a non rooted backup up img and performing a hard reset take it back to stock or will a flag still be set?

Regards,

Steve

After upgrading to Kit Kat now my tablet does not work with Miracast anymore. It worked fine yesterday, when I had JellyBean running.

When I launch the screen mirroring app on my tablet, it scans and finds my miracast dongle. I can see it acquiring an IP address and it shows it as connected, but after 1 second I get a message saying something like "Unable to start Screen Mirroring because of a hardware issue"

I've tried rebooting all my devices but no luck. It seems as it's a known issue ( http://xdaforums.com/showthread.php?t=2542509&nocache=1 ?

Anyone tried screen mirroring with KitKat ?

A new updated build (France) has been pushed out.

Probably bug fixes, hopefully KNOX is still not fully implemented.

Great work, faria. Successfully installed it on my Samsung Galaxy Tab 3 8.0 WiFi only (SM-T310).:D

I installed the update and got root. Everything works including the wifi icon which somebody said dissappears.

It's a bit laggy after flashing the rom (NO DATA LOST) but it's all fixed after factory wipe.

I put some screenshots below.

The thing I hate is the new video app. Can someone PLEASE :crying: post an apk to the older version of the video app.:victory: (screenshot below)

The only thing is I didn't have guts to install custom recovery. :p

Battery life still the same from before.:D

I'm new to xda so take it easy:)

? The only thing that I really miss from the JB firmware is the "Dolby" sound in the video app... it used to have a great sound effect.
[Galaxy Tab 3 General] 007Uzzi:
If only someone could give us the apk to the jelly bean video app ?

---------- Post added at 08:22 PM ---------- Previous post was at 08:18 PM ----------

Or even port the damn video app....?☺Anybody please.... For the sake of the community.

The kitkat video app is terrible and there's no dolby sound effects.?
[Galaxy Tab 3 General] clemmie:
I've had great success with the vlc player video app. I actually switched it to my default. Give that a shot.
[Galaxy Tab 3 General] 007Uzzi:
Cool, I like the video sound effects☺

But I still think the original jb video player is in it's own league because its more easy to use and the ui is more neater. But thanks I love this vlc player. I totally forgot about it when I upgraded to kitkat.☺

If anybody could still try to get the old jb video player back for us, it will be much appreciated. ?

And if anyone needs help with any of this kitkat upgrade stuff, I would be glad to help.
[Galaxy Tab 3 General] 007Uzzi:
Mx player is even better. With the s/w audio decoder you can boost the sound up to number 30 which is exactly 200% louder volume without sound distortion. ☺☺☺

I think that is all to kitkat and it's safe to upgrade.?☺?
[Galaxy Tab 3 General] marek_poland:
But on JB's video player there was really great drivers. In my opinion with the Dolby there was awesome bass booster on tablet's speakers, which isn't present on actual KitKat builds video player, especially in MxPlayer which I'm using.

Sorry for bad English:)

Best greetings
[Galaxy Tab 3 General] 007Uzzi:
Yea! We need the jb video player! ☺☺☺

Can anyone get it for us?

I tried every player but the jb video player stands out of them all.

Faria? Anyone? Unfortunately I'm not a developer.?

And if someone can get it for us then everyone gains benefit from it.

Please help us in this regard. ☺

Help. My tablet galaxy tab 3 sm-t3110 8' . I cant find rom, cwm, i am lost.
[Galaxy Tab 3 General] aliafzal97:
I am not much into rooting so i needed a bit of help.

I was able to flash the kitkat rom manually.

now i want to root, so i wanted to ask you which version of odin should i use to flash cf auto root file and which all boxes should be ticked in odin.

if u could please give me a link of the correct odin version, that would be a great help. And also tell which boxes to tick in odin.

Thanks a lot :)
[Galaxy Tab 3 General] 007Uzzi:
Use the same version you used for kitkat. The first box should be blue and auto reboot unchecked. Everything else is the same. click on ap and choose the cf auto file (post #1). Then click start. It will about 10 seconds and say reset. The keep it still pluged in and hold the power button to shutdown. It won't shutdown but actually reboot. The Samsung tab 3 sign will show, then the scary cf auto root red bot page and then continues with normal startup except it will say android updating. Grab a cup of coffee and give around 15 to 30 mins. When it's done, unlock your phone and go to super su. It will say knox detected, do you want to remove,Select yes. Then let it's binaries update. After that you ready to roll. Cheers☺☺☺

Don't forget to smash my thanks button!☺?

[Galaxy Tab 3 General] kirokko:
Is it possible to install this update without installing bootloader another way via desktop odin (not mobile odin)? Which file from fw I must remove (tar.md5)?
[Galaxy Tab 3 General] ketut.kumajaya:
First, the md5sum for safety. Odin will check package integrity on the fly based on md5sum content in the end of tar file. Fairly easy to repack for Odin on Linux machine:

mkdir firmware
cd firmware
tar -xvf ../<name of the firmware>.tar.md5
tar -H ustar -c system.img recovery.img boot.img cache.img hidden.img > <name of the firmware>-without-bootloader.tar
md5sum -t <name of the firmware>-without-bootloader.tar >> <name of the firmware>-without-bootloader.tar
mv <name of the firmware>-without-bootloader.tar <name of the firmware>-without-bootloader.tar.md5

On Windows, I'm not sure the default format of tar file created by 7zip but you can try. Name it without ". md5" prefix.

stock recovery

hi guys i updated my t310 to kitkat and the recovery wouldnt work so i installed a custom recovery which worked fine however is there any way i can go back to stock recovery
[Galaxy Tab 3 General] MRC01:
Thanks - it took me a bit of reading to use Odin for the first time but this worked perfectly (I had rooted Acer tablets before but never Samsung/Odin). All features -video, audio, wifi, etc. are working just as before. All my data was preserved. Performance is great - just as before - with no need to factory reset. And now I can make the external SD writable by all apps like it has always been. :D

I was already on 4.4 and this did not intoduce any new bugs. The WiFi bug was already in the factory issued 4.4 update. This bug: Wifi icon disappears from status bar, Wifi can't be enabled in settings, but even though it shows up as disabled it stays connected and working on whatever Wifi network it was last connected to. The workaround is to enable airplane mode, then disable it.

Update being pushed now?

I just got a notice today of an update from Samsung(?), and am downloading a 691.96 MB file now as a result. Is this KitKat? Are there any particular benefits, or disadvantages, to be gained/lost by updating from the current 4.2.2 ?
[Galaxy Tab 3 General] arisps:
samsung t310 dolby surround

Just Dont update. Keep the jellybean 4.2.2 . Kit kat 4.4.2 is nothing special, plus you will miss the option of writing-copying-erasing to your sd card from es explorer (that is not so important) but the MOST IMPORTANT is that you will miss the option of the great sound that the tab has when you see a movie.

I wish i could find this option again to the new movie player, the option of the sound effect (higher and greater surround volume). If any one find how to add it again please to inform.
[Galaxy Tab 3 General] rokkywoof:
Thanks for the heads-up. I killed the d/l as I got to wondering how much control I would have over it after the d/l finished, and decided it was not worth the risk. I have gotten quite leery of Android updates since Moto killed off Webtop on their phones after ICS, and the general UI seems to keep getting weirder (i.e., new/different :) ) with each version.

I will try to find out what other diffs there are for a more complete view of pros vs cons.
[Galaxy Tab 3 General] 007Uzzi:
Got an idea!

I just got an idea.....

Earlier when someone said offline charging doesn't work, does it mean it doesn't charge or the animation is not working?

If the animation isn't working then we can flash a custom 4.2.2 rom that has our dolby sound and favourite video player and it will still charge so we not stuck when the tab is drained . Not the stock 4.2.2 but a custom rom on 4.2.2 that's identical to stock or similar.

Please give feedback on weather if it will work or not....

Hate 4.4.2....... sluggish, lags, bad battery and sound sucks!

Any help or feedback would be appreciated. :)
[Galaxy Tab 3 General] oibaf79:
Hi,

i have the last 4.4.2 (KOT49H.T311XXUBNI2) on my SM-T311 i can use kingo android root for rooting?

The counter flash will be zero, even if i use the guide for root in the first post?

Thank you.
[Galaxy Tab 3 General] arisps:
I m not certain that we can change the 4.4.2 rom and downgrade to 4.2.2. It has many risks..If somebody has tried this because i dont know much could tell us. And if we do rooting, we miss guarranty. I tried mx video player and it has an option of changing audio decoder that increase the sound but it is not the SAME we had in jellybean. Samsung MUST give us an update to fix theese issues.!!! Lollipop maybe is the solution!!!

The tablet does not charge from the usb port when it is turned on. When it is turned off it charges normally but it needs more time i think

The greatest will be if we could add again the Dolby sound as an apk :good:
[Galaxy Tab 3 General] 007Uzzi:
Found A Solution

After lots of research .................... I found a solution to our Kitkat sound problems:laugh:

There is a root app called Viper4Android that I ran into somewhere around Xda.:cowboy:

It gives better sound quality & loudness than Stock Jellybean.:good:

The sound it crisp & vibrant and totally better than the dolby.apk app.:D

This is not my work / app and all work goes to Viper520 & ZhuHang:good:

And for all the lag just switch all animation scales to 0.5 in developer settings.

For the bad battery life just use the Greenify to hibernate those apps and you're good to go.

One more thing: Don't forget to smash my thanks button:good::highfive:

Doesn't work for CM11.

---------- Post added at 05:54 PM ---------- Previous post was at 05:50 PM ----------

Have you tried debloating?
[Galaxy Tab 3 General] 007Uzzi:
I'm not sure about cm 11 but it definitely works on stock kitkat with root and twrp. There's a MAJOR difference in sound quality. Just go to the equaliser and set it to custom. Then crank on the sliders right to the top. Make it louder than any other device I have ever seen. And there's no sound distortion :)

By the way there's nothing much to debloat and I use most of the samsung apps so that's not an option. Infact on JB I wasn't rooted and it was as smooth as butter, and super snappy. The specs are pretty decent on this tablet so I expected much more for what I paid for it. Looks like we have to get use to the lag....

And lastly when the developers say that offline charging doesnt work, does that it doesnt charge when off or just the animation doesnt work?
[Galaxy Tab 3 General] guest_2011:
Still doesn't work. Maybe i'm doing something wrong.
[Galaxy Tab 3 General] 007Uzzi:
Tell me exactly how you do it and I'll correct you. How do you know it doesn't work?:confused:
[Galaxy Tab 3 General] guest_2011:
Uninstalled, reinstalled, selected different audio drivers, different settings, boosted equalizers, rebooted, no improvement, uninstalled. What driver did you chose? What settings do you have enabled/disabled? I'm on cm11, if rom makes any difference.
[Galaxy Tab 3 General] 007Uzzi:
Cm 11? You're on the wrong thread......

But anyway at first I had the same problem but then I started from scratch by reinstalling KitKat from Odin then rooting and then finally flashing cwm. Then I installed by busy box and the checker and made sure everything was working in busy box and finally viper4android worked!

Still next time please post in correct thread related to your issue as I have never used cm Roms:p

---------- Post added at 10:46 AM ---------- Previous post was at 10:39 AM ----------

One more thing, are you experiencing a driver install loop?

Because if you're not click on the menu button and then click driver status it will show you driver installed or something.

If you playing music in the background then that menu will show that it's processing the sound

But if not then I'm really not sure of what is the problem.....
[Galaxy Tab 3 General] guest_2011:
I know this is not CM11 thread but there's no discussion about improving audio in 4.4 on cm11 so i came here looking for alternatives. Maybe Viper is not compatible with 4.4.4 but works with 4.4.2 based roms. I will eventually downgrade to the official update and use your method for Viper.

No, i didn't experience driver install loop.

I wanted to post in the developer forums about getting help there BUT I CANT POST THERE because im new, so please have mercy on my sorry ass...

Ive been messing with my new Find 7a for 3 or 4 hours now, Ive managed to get the thing rooted but i cant for the love of god seem to install gummy rom.

I read stuff about having to install CWM or TWRP and I have followed the guides here the BEST that i could to try and get rid of the stock recovery but neither of them seem really informative about what to do and im now incredibly irate because I cant seem to make sense of whats going on, what to do or what i can do to get Gummy installed before i go to bed tonight.

I apologise if my post seems a little stressed and I honestly shouldnt be but I was really looking forward to having gummy installed on a new device and i dont want to start using my Find 7a until I have gummy installed.

If theres anyone who has already gone through the entire process and managed to get theirs to work, I would apreciate it GREATLY if you could just walk me through the steps so I could also enjoy this amazing phone.

Either I get this working or i down a pint of whisky.......Because Im really at the end of my rag with this.
