Thanks for your work but I found some inconsistency...
I try to recover my tablet from the "bottom reverse scrolling problem and I could not get it work yet so I did some tests.
I found something out:
This is the latest fw for the A19 touchscreen and also works on the 101H too. Use this one to if your not sure.
then you wrote:
This is the firmware from a similar tablet (DVC P10). It works (badly) on the P10AN01 but If you have flashed the latest 101H fw to an A19 touchscreen, flashing the correct firmware wont fix it (bottom half of the screen touches are reversed) you will need to flash this firmware first and then the original test rom, calibrate, flash the new test rom, install tputility2, flash correct firmware for your touchscreen and and then flash original test rom to calibrate.
The files did somehow match too exactly.
so I did a checksum (SHA1) on both Firmwares and detected, that they are identical
So can you please reupload the original recoveryfirmware again?
thanks in advance.

What a ton of work - but unfortunately my Viewpad 10s is now not booting.
I've used NVflash to flash 4 of the images linked to in this thread including the stock 20110411_v1.10.4_std_dev : after each one it starts up to the green Droid showing for ~2secs, then goes blank.
So I tried VGAfixer from http://www.modaco.co...is-will-fix-it/ .
and despite the bootloader.bin file in its folder its batch file readsthat it doesn't find it:
rcm version 0X20001

Formatting partition 11 UDA please wait.. done!

Any clues in the above?
Viewpad screen stuck showing "Entering NVFlash recovery mode / Nv3p Server"
Newbie at this so please excuse if have missed the obvious ;-)

Sorted used the viewpad rom and the screen came back to life, flashed on a new rom and calibrated a few times and now works nicely.

My 101H touchscreen as been playing up for months. Over sensitive in places, dead in others, double touches, ghost touches etc.... I've tried all the firmwares and whilst sometimes i can get the testrom (1.10.4) to work perfectly, as soon as i flash any other rom including the original advent one it just goes back to playing up..

Unfortunately one tablet did not go after the upgrade. I noticed that they are not soldering the pins in ITE. After resoldering ITE, FW works without a problem.
Yellow / Orange pins not soldering.
Resoldering pins OK.

Have to say that I also had the reply "cannot load fw, upgrade failed" ( or something like that ) with fw 99, tried again with fw 101 and it worked like a charm !!!! My device is POV MOBII, now resurrected .
Great forum , great people.
POV MOBII on VegaCream+LG Ox2 on ICS CM10.1. Thanks to all great devs!

I know this is an old post but I'm stuck.
I have gone round and round trying all the firmware versions on this thread and after succeeding in getting the touch working, it's now got the lower cm reversed problem.
These are the versions I have tried, in many different orders over many many evenings of trying.
Lots of different versions of these from all the links on this thread.
Has anyone a link to download the newer 188.8.131.52 firmware and config?
Or has anyone any other recommendations?
Thanks for your help,
