You can go to this OP

or

A) Flash through Odin 3.07 the TWRP, I used openrecovery-twrp-2.6.1.0-blackhawk.tar.V2.zip

B) Install through TWRP the android-armeabi-universal-root-signed.zip; Wiping is recommended

C) Update the SU and is done!

Thanks for your answer , I have not found this as a known issue, reason why I asked if anyone knew about this, doesn't affect me but I was trying to do some research maybe had good luck

Hi @Viktorcito, I've stumbled over your question just know, next time you can use my new [SM-T210/T210R] RocketTab Support Thread for everyone to post a question, if you can't post in the development section yet

I've just tested this on my own and cannot confirm @safariking's answer. If the tab is off, usb connection shows regular loading screen. If the tab is connected via MTP or PTP, there is an icon displayed which seems to display "not loading", but if you let it connected for some time and go to accu settings, you will see, that it charges over time...

I've taken a screenshot, see attachment...

@tempdroid , first sorry for the new thread but I didn't find the one for everyone; tried connecting the tab to the PC and wait around 15 min and still show Discharging as pics attached, if the tab is off it charges normally but not when is on, do you think is something related to the kernel? let me know if something that I can test; once again other than this I'm very happy with the performance of this ROM

regards,

Hi @tempdroid sorry to bother you, I noticed something when I connect the TAB off my PC recognizes as different Hardware than usual so I decide to remove all drivers, turn on the TAB and windows install again the drivers now on the graph shows that now is charging but with low frequency, it takes almost 20 min to charge just one % so the entire charge will take for a while, it think this is the reason that the tab doesn't recognizes that is charging and show "Discharging" maybe there's an app related to this, let me know anything you may need,

actually in stock rom or this rom (or any rom for t210) it doesn't show charging when connected to pc via usb coz of the x in battery icon, but it's still charging. you will only notice it when you unplug the tablet that your battery gone up.
