No problem, Android manages the memory for itself.

Check out this thread. But you will need root to apply the workaround, FYI.

[Q] Did I just brick my phone?

Well, I just received my phone today and I decided to root it by following a guide. Little did I know that firmware I was rooting was not meant for this phone. Now the phone shows the Samsung screen for a split second and then it turns off.
Is there anything I can do to restore it back to normal? I only have access to download mode right now.
Pm howtomen hrs helped someone earlier today in irc. not sure how. But you're still ok

He helped me...long story short, there's not much we can do until a stock ROM is available.

Ohh ok thank you both for the quick replies. This sucks, I don't have a phone now untill I can get this fixed :\
So where did the dev forum for our phone go? Is it mixed in with the other major 4 US carrier versions?

It seems to randomly disappearing and reappearing.

If you can get into download mode you're ok. You need to flash a stock rom and you'll be back to normal. Don't flash chainfire's root from the international thread because the kernel is not the same.

@OP - I'd better not see you bump a post after 9 minutes on here ever again :-/
I'm not interested in how important you think your issue is, this is not your personal tech support forum. When you make a thread, you wait patiently for an answer. Bumping your thread after not getting an answer within 9 minutes is a good way to have people ignore you (which the person who did answer you should have done to make the point).

hey buddy, u r new to all this rooting and flashing thats Ok.
and also ur interested in knowing more about the same thats also fine.
but ur handicapped with just ur phone to do everything, which is not good.
since u need a computer and internet connection, so that in case if something goes wrong while doing things on ur phone, at least u can get help via PC from XDA or google to resolve ur issue.
hence my advice to u is, do please get hold of a pc with net, may be a friend of u might help with the same.
also u have to do some probing on XDA regarding
1) how to root my phone?
2) what is downld mode and recovery mode? etc
hope u understand for now

dmtech 723b root & su problem

Been searching like a moron for anything to solve this problem. I have a dmtech 723b wich with rootchecker says i got root. But i cant use su or anything else root-related. It is original jelly bean so i have not tampered with it in any way. Would really lika to be able to do all the things possible on root and even try custom roms on it, but i cant.
Please help me!!!!
Bump
Sent from my MB525 using xda premium
Nobody who knows how to obtain SU on the dmtech tablet 723b? as stated before, rootchecker says it has root.. but no SU-apps work..
PLZ help
Id happily give all info and files needed for finding a solution to this. This is a cheap and common tablet so i think there are many ppl who own and use it.
Managed to get partial root and su thru superoneclick, but get errors when using i.e. luckypatcher and/or rom toolbox. =(
