I've used C. Troy's compatibility zips - great work - but have so many tablets that aren't on his list. I spent 5 days trying all of grandmother's ROM's - terrific work for forgotten tabs - on the Cruz, PS47, 800*600, IT7260-TS, 8188-WiFi but had no luck in finding one with TS function. Many came up beautifully - I did a long list of what did and didn't: U16GT; Odys Neo 8; Newpad P9 look good - XTean JB; PMP5080B (oem), Odys Xpress (oem) look super. Alas, no TS function. G-sensor would be nice but not mandatory. Where do I start to learn the basics and tools? I don't need to rewrite a ROM, but replace hardware device handlers (kernel, HAL, both?). I have an SE background and do mucho tab electronic repairs including hot air reflow, but moding ROMs currently escapes me, and I don't find the instructions on the web all that clear...oh! hopes of crystal clarity...As R. Feynman said best - above all, clarity.

Here is what we do, so I run into many, many ROMs that justify reworking (about 300~400 tabs in my lab): We are a two-person venture. We focus on R3 (Recovery, Repair, Reuse) of Tablet/Notebook PC's to gift to needy children and the disabled via NPO's (Non-Profit Org's); >2700 PC's to date. My disabled son coordinates, final QC tests and ships the technology via NPO's to the needy. Using my “Capitalism for a Cause” venture model, our small-scale sales center feeds working capital to our “not for profit” arm for inventory acquisition and repair parts. Our hope is to make a positive difference for those in need. With "Hope" one can imagine, one can work, one can dream. I fund this work with my DVA pension (USMC, Dom. Rep. 65; RVN, I Corps-North, 65-67). See my eBay profile, OTPC means One Tablet Per Child.

AYK - Many "resellers" of PRC clones are not open with their ROM images, definitely do not invest in version upgrades, but surely push designed obsolescence. Not good for those into technology recovery, reuse.

Any help out there will be most welcome.
