clock outside notification bar Samsung Tab 3 GT-P5200

[tiagosgd]

Hello.
I am the owner of a samsung galaxy tab 3 (GT-P5200).
I updated it to 4.4.2 (kit kat) via OTA.
Then, problems with my clock of the notification bar.
I cleaned cache. I went to Samsung Customer Care... I deleted all my apps...

I think that this is a problem of Kitkat. Maybe, if I can downgrade...
I downloaded 4.2.2 and install it via odin, after complete format via TWRP). But, after the installation, the tablet doesn't start (only "samsung galaxy tab" flashing).

What can be this problem of clock?
And how to downgrade?

Thanks
Tiago

You cannot downgrade. But you can factory reset the device in an attempt to fix the problem. If that doesn't work, then we will need to reflash to software onto it

 

[KaosMaster]

And you need to Odin flash 4.4.2 stock back onto the device

I factory reset it already!
Reflash is to format the tablet and install everything from sammobile? I did it before.

 

[KaosMaster]

Yes. But it sounds like your rooted. And that will break your root. You can use kies 3 to accomplish this as well. But you will have to reroot when completed. Make sure you have the right options ticked when you Odin!

Auto reboot
Repartition
F reset time
nand erase all
Bootloader update
Clear efs.

That will get you to complete stock

It is unrooted.
How can I use kies 3 to do that? I only know with odin.

 

[KaosMaster]

Install and open kies 3 as administrator.
Update if asked.
Plug in device.
Go to tools menu
Upgrade and initialize

With the tablet in download mode?

 

[KaosMaster]

Yes. Since you can't boot it.

 

[tiagosgd]

Ok.
So, i will format the tablet.
Than download mode and connect to kies. Thanks

After you repair it. Factory reset and flash again to make sure its right with battery at 100%

No problem!!

Just done this via kies. Now waiting to see if anything happens.
