[Q] Trio Stealth G2 - Android Q&A, Help & Troubleshooting

Hey,
Tried as hard as I could not to have to ask, looked everywhere I could think of, searched through dozens of threads and found nothing in regards to my Trio Stealth G2 tablet.
My question is, what method of rooting should I use for my tablet, and once I do root would there be a custom ROM I could use?
I've seen people mention they messed up flashing a custom ROM to the Stealth Pro 7, but I'm not sure if any ROM made for a 7" Cortex A9 tablet would work. Don't want to brick this though so thought I wouldn't chance it.
Thanks

Trio Stealth G2
Just got this tablet today. I was able to root it using the One Click Root and it has rooted it properly so it would seem so far.

Hi, slick97477. Where did you get the One Click Root tool? I didn't see any forums for this (or any other Trio) device on here.
Thank you in advance.

One click
I got it from here
just google oneclickroot
and just run it. Couldn't believe it worked but it did.
However today went to try and turn it on and nothing, Just hung and the Trio logo. Let it sit for about 10 minutes. Decided maybe battery was dead and plugged it in still nothing. No battery logo nothing. Hit reset button and plugged it in again and nothing. Screen doesnt come on now nothing but however weird thing is it shows up as winusb now under devices which is amlogic driver for flashing firmware which im not sure how this has happened but it has. I have took it apart and took pics of the mainboard and cpu. Would like to see if perhaps there is firmware out for this...Have done quite a bit of research and numerous different things so far..
I have downloaded the firmware installer from amlogic but so far no firmware seems to like my cpu....Hmmm well cannot upload pictures yet for some reason..If anybody is interested in trying to help me figure out which firmware will work on it I would greatly appreciate it. I used it the night before and it worked great. Have not installed anything new or anything so I am a bit baffled in how the firmware got torched but I am pretty sure that is what has happened any ideas I am willing to try. I have recently dived into really messing with the android devices but had not done anything with this tablet yet because I had not found a way to back up the current firmware on it...so was really being nice to it for now....
(Edit) Pics are included just didn't try hard enough

Trio Stealth g2 tablet issues
Hi I was reading your posts about the g2 and I seem to be having a similar issue. The tablet is frozen on the trio stealth g2 loading screen and I have pushed all the buttons including the reset button on back to no success. I got the tablet to recognize as m3 chip on my pc and was able to aml flash tool but every time I try to upload a rom like stock jellybean or some custom rom its asking for a upgrade config file which of course I do not have there has to be a way to just completley wipe this tablet and install a new os any ideas on how I can get this thing to flash, I was hoping I could load a sd card and push some buttons on the tablet to flash from the sd card but I have no clue if thats possible

I too have a g2 with the same issue but i've gotten it into ADB Recovery. When using the AML Flash tool, after you import the upgrade file and it asks you to manually input a config file use the config_progress.xml file that is in the AML flash installation directory possibly under \resource\
This is what got me to ADB recovery but anytime I try to reboot the tablet it reverts back to Worldcup Device in device manager so I'm stuck. Hope this helps.

Hey I was able to flash the tabley with aml but I used novo 7 fire and now nothing comes up, no boot screen or anything, however when its plugged into my pc I can access the internal storage and Micro sd card storage, but I need to remove the rom and get one that works correctly for the tablet, unlike before It wont let me push the power and vol button to make it go to the m3 chip which then I could use the aml world cup driver so some how I have to flash it from the internal storage or by some means but I have no clue at this point. The driver is Portable media player MID Novo7 I changed the driver to android ADB which it installs but then I cant access the internal storage, is there anyway to re flash this? I tried pushing diffrent buttons on the tablet to see if a diffrent chip is recongized like the m3 was from before but nothing

From my experience with the stealth g2 9.7" if you open up the tablet and use a pin or small screwdriver to short (connect) nand pins 7 & 8 (counting down from top right of chip, yours maybe 5 & 6 or 6 & 7 ) as seen in picture below the circled area, while powering the unit on, should erase the nand and revert to Worldcup device in device manager which will allow the AML flash tool to see the device again.

Nice! Glad it worked. At this point we're in the same boat. I'm not sure how to properly flash a new firmware even though i've got an identical working one. It seem's I've tried everything and the closest i've gotten is just getting the screen to light up blank, which hasn't happened in a long while now. I used the instructions in the PDF file below except i replaced the bootloader.img, boot.img & recovery.img files from a backup I made, ran heroflash.bat and rebooted the device and now the screen comes on blank. Not sure where to go from here though. I'll keep trying

It looks like there's an issue with that specific u-boot.bin (u-boot-orig.bin) within that package. Although the fact that it shows up in device manager as Portable device means that part of it was written by the flash utility. Have you tried force-ably replacing the drivers from portable device to android adb drivers. This might allow you to access the adb recovery mode.
Alternatively if ADB doesnt show any devices after replacing the drivers, you might want to uninstall the adb drivers that didnt work, once it appears as portable device again, the tablet might be looking for its new firmware on the sdcard. Check out the page in the link and follow the instructions for "Method One - SD Card Method for a "soft" brick". It involves restoring a factory image onto the sdcard using a handy tool "USB Image tool" and then rebooting. It might kick in an update from the sd.

Also I could upload the aml flash files that are getting me into adb recovery mode every time
