This should be a relatively easy question, hoping maybe one of the WM8505 masters (tipstir?) could answer from their research. I can't be the first one to try this. I've recompiled the kernel for WM8505 (aka vt8500) and would like to try it out, but if I just replace the kernel in a known working (on my tablet) ROM "script" folder I know that will flash my custom kernel, BUT if the kernel is broken (which it no doubt should be, first time around) is that the same kernel it needs to load for doing updates? Or is that in the w-load (u-boot) somehow? Or is the upgrade process kernel-less? It seems to me it partially boots at least the existing kernel with a different init to implement the /sdcard/script functionality. So I'm thinking if I break the kernel in the flash then I have a possibility of completely bricking myself out of trying again (like if my compiled one can't access flash, etc). However if you know I can load a "nasty" kernel (as compared to the "dirty" one it had originally, lol) and still retry that would be all I need to know. Not really that in to shooting myself in the foot as I've done that plenty of times with OpenWRT and routers and stuff. Also how do you pry one of these things open, I'm gonna need the serial console for sure. All this is to try and get something newer than Donut running on these (lofty target: actual real Honeycomb build, fallback target: at least a full Gingerbread) and maybe help consolidate all the clones under one kernel that works for them all instead of this weird compatibility matrix we got now. Thanks.
