There's like 0 support for this model. It was bought from Sears. I was going to just buy another one of the same one and dump the image from the new one and load it on the old one but they don't have this same model anymore. I also looked online for the exact model as well as the firmware but can't find it. I have the parameters and the settings and everything, like I said I have the script.bin from the original so I know exactly what drivers it uses and everything. The drivers are installed it's just not calibrated properly. Here's the system info and a text document of the script.bin.
I've done that, I've even tried replacing the whole thing. Everything works perfectly fine it's just the touchscreen calibration. I tried changing values to 0 and deleting some and commenting them out and even changing the format of how it's written from the new script.bin to the old one. All I need is to calibrate the screen. Everything else is perfect. And I spent over a week messing with the script.bin.
Unfortunately I couldn't find the stock rom and I went through all the 13B roms and a few more Sun5i roms in the A13 rom collection and none of them work :-/. I guess I'll just wait till I can find the same model and transfer over the image or hope more support for this model becomes available. Thanks for taking the time out to respond.
I've tried several drivers in and the solomonsam worked best. I did find a modified version of it from lithius but that one caused the screen to be 180 degrees off and the same problem persisted with the calibration. I can find several working roms but any of them that has the touchscreen working seem to have the same calibration problem. I had found a link a guy posted on how to manually calibrate a chinese tablet by changing the values in a notepad but whenever I try any change my rom stops working. If someone knows how to manually calibrate a tablet that would help a lot.
on the right side of the screen the touch is a little off to the left. But then in the center of the screen touching doesn't work at all. And then on the left side of the screen it's off to the left and up

And then on the left side of the screen it's off to the left and upI'm having the exact same problem as you do/did with my Trio Stealth Pro 7c. My original firmware was fine, but after trying several ROMs (including FaaastJB v1 and 2, CM10) my TS seems to be broken. I managed to revert to the original firmware with the Uberizer backup I made, but the problem persists. I also tried another Uberizer firmware backup someone over at xda uploaded, but the touchscreen remains uncalibrated. Now, I strongly suspect that what we are experiencing is related to this http://www.freaktab.com/showthread.php?1545-How-to-fix-a-A10-AllWinner-ft5X-touch-screen!. The site mentions that the TS chip's, in my case a ft5x, EEPROM is erased when flashing a custom ROM and that even when going back to your original ROM this EEPROM is not reflashed, leading to a badly calibrated touch screen. I have only just come across this information and have not been able to try it. I have found that the line mentioned the post (ctp_fetch_sysconfig_para: script_parser_fetch firmware_upgrade_used = 0) is indeed missing from my TS driver. I am not exactly experienced, so if people here have ideas on how to proceed, all help is welcome!
I have also seen some of the ctp_para sections on certain Roms with the firmware Upgrade lines...

You don't happen to remember on which ROM you've seen it, by any chance? And did you use it on an A13 tablet? Finding a ft5x_ts.ko driver with that line apparently is half the work of fixing it..

Would you be able to send me the firmwares so I can try it on my own tablet.
I have no idea why it wouldn't work.. I managed to install the XDA backup perfectly fine.. I've been using uberizer version 1.6, option i4 as well.. I'm sorry I can't be of more help. Interesting my tablet needs two drivers. I had the screen replaced, could that be why it needs two drivers instead of two?
I came across a forum page that says if you use an uberizer backup, the current rom you have on your phone has to be the same android version as the backup. In otherwords, if the backup is 4.04 and my current version is something like 4.2.2 then I have to first flash a livesuite rom with 4.0.4 to use the 4.0.4 uberizer backup. So, firstly, what android version are the backups so I can figure out exactly which version I have? Second, would you happen to have a livesuite img with that same version? I was looking on the rom files for A13 and assuming it's a 4.0.4 so i got one, but the one I got is not rooted and my computer doesn't recognize it plus the touchscreen is unresponsive so I have no way of loading the adb drivers in order to use the uberizer backup. :-/
Both backups are version 4.0.4. This ROM should work with your tablet. I've used several times to revert back to my own Uberizer backup.
Also, Twjordo, if possible, would you be able to post the XDA rom that ersatzorama posted also considering it is the only stock rom I've been able to find anywhere for this phone, or does it have to be a livesuite rom and not an uberizer backup? If so, do you know how to make a livesuite image so if I get this phone fixed I can create one to upload on this site?
