So your slot 1 and 2 booted? I was able to create a slot and install a rom, but when I boot into it, it just hangs at black screen. I have to pull the battery to get back to recovery to select main slot. Would be really nice to get a fully working safestrap for KK.
I never noticed any errors? I tried it a couple times but no joy. I can try again and see if I get any errors. Will report results later. I do know that the dev has stated that 3.72 beta was not capable of installing multiple rom slots, but have heard others with success, so not sure if it is just by chance the few have gotten this to work or what.
Also, if it can't mount the system your ROM slots will not be created properly. You can tell if they didn't work by looking at the size of the system partition after creating the slot, if it didn't work it will say 0 (zero). As someone else suggested, if you increase the partition sizes (even by the smallest increment possible) they will get created and work. The only thing I've noticed is that rebooting does not work and requires a battery pull.
Hopefully this helps you.
Saweeeeet!!! Total success. I wiped the slot and re created it with uping each of the three partitions by one bump. That did not work as the partition size said 0 space available. So I wiped again and just bumped the first two up. That time it took and showed the partition at correct size. I installed Hyperdrive on it and it installed and booted just fine.
Thanks again for the help. Totally stoked that I can test out other roms again without wiping the main slot.
