In this thread i am going to show you how to unbrick your gs7013b tablet without recovery mode.
Please be aware that i have spent a lot of time researching and sourcing the resources to be able to do this and it may or may not work for other MIPS tablets....
firstly you need to set up your computer environment (drivers etc)
Actions Product Tool 1.02_02 (Developer Edition)
When you have finished download the above files extract the actions developer tool to a folder on your desktop for easy access and do the same for the firmware files.
Now we need to get your tablet into ADFU Mode (ADFU = Actions Device Flash Utility)
FOLLOW THE INSTRUCTIONS CAREFULLY OR YOU WILL HAVE NICE LOOKING SQUARE FRIZBY
firstly open up your tablet by popping off the rear panel.
when you have opened the tablet up you should have something like the below picture.
Now to get the tablet into ADFU Mode connect your usb cable to tablet and computer and remove any memory card you may have inserted.
now you need to find a tiny flat screwdriver or knife or something similar and we need to short pins 7-8 or 8-9 on the tablets nand chip to force it into ADFU Mode while shorting these pins keep pressing power button until computer recognizes it.
see picture below.
NOTE: i have been informed by some users that the nand chip on their devices is actually soldered on inverted to find pin 1 simply look at the chip and in one corner there will be a little circle which is sort of sunk into the chip this means that pin 1 is on the same corner as the little circle..
when you get the tablet into ADFU Mode your computer will make a sound as if you have just plugged in a usb device. Your computer will now ask for the adfu usb driver which you should have in the Actions Tablet Product Tool 1.02_02(Developer Edition)\Tablet Product Tool(Developer Edition) 1.02\Driver\ folder on the desktop which you downloaded earlier. point windows to he driver and you should now have the device installed...
now goto the Actions Tablet Product Tool 1.02_02(Developer Edition)\Tablet Product Tool(Developer Edition) 1.02\Product folder and run the mainapp.exe
the tool will open and then ask for a firmware file choose the icecream_gl5201_q8_rgb.fw which was in the firmware files zip you downloaded earlier
Now when the tool has read it you need to click the button as in the picture below.
Now on the right of the tool there are a few check boxes etc LEAVE EVERYTHING ALONE apart from the 2 options i explain below
click the image button for FAT_MISC Partition and choose the ACTA.IMG you downloaded earlier in the firmware files.zip
no click the image button for System Partition and choose the ACTB.IMG you downloaded earlier in the firmware files.zip
Now click the big green button as in picture below.
when flashing is done reboot tablet if it doesnt reboot automatically
BOOM working tablet... you should now be able to use your tablet with what you just flashed or you can try a different rom using stock recovery
massive thanks to
Edo2013 (xda forums) for helping me with software and firmware sourcing and flashing.
EDIT: IF YOUR TABLET WILL NO LONGER GO INTO ADFU MODE AFTER BAD FLASH AND SEEMS TO BE TOTALLY DEAD USE THIS METHOD TO GET IT WORKING AGAIN
