Im being kind about the bugs!!! Its interesting how firmwares adapt to individual machines.
Although periodic slow internet, crashing apps, and other bugs are annoying, I found factory 12/23[original, not 1/12 version] to be unstable with 20+ crashes/restarts in 24 hrs. 12/24[wifi optimizzation] seemed to be the best 2.3.4 for my use.
Can the fastboot be applied to gingerbread?
I am in contact with the closed beta group currently testing the latest firmware and as soon as it hits my machine, I will pass it along. From what i gather, it is coming along nicely and we should have Official 4.0.3 soon.
Not sure of your skill[no offense meant] but devs and tinkerers are needed to optimize this tablet.
As far as the custom kernel, what improvements will it bring?
I own a haipad m7[herotab,dropad] and have seen amazing development using the 126.96.36.199[both honeycomb and ics working]
