It took a while, but so far, it didn't bring much for the prospects of Ice Cream Sandwich on P1010. Actually, there's no clear path to get a solid (custom) CyanogenMod 7 on P1010 just yet.
1. Clockworkmod recovery
This is one necessary step, and an attempt was made by Skin1980. Procedure described there is quite simple and straightforward:
1. Reboot your device in download mode. That is, a "normal" combination of Power ON--Volume UP buttons, only out of device fully turned OFF before that;2. Open Odin;3. Select the attached file in the PDA field;4. Flash it.Flash presents ClockworkMod (CWM) 5.0.2.7 and root in one package, so presumably a road to CM7/CM9 or any other popular custom ROMs and kernels is open -- just like I was suggesting in my previous post on P1010 here.
However, things get a little hairy after that.
2. ext4 conversion
First, the conversion to ext4 file system is needed after that. It involves flashing a kernel that is modified to include ext4 partition(s). Flashing it via CWM that doesn't support ext4 partitions just yet is quite problematic, so the kernel is zipped into a .tar that may require Odin. Consequently, after that is done, it's no wonder that problems may start with apps, with whatever was restored from backups, and overall system stability. Is the CWM version solid enough or how good it was adapted to P1010 bridging the different file systems, remains to be seen.
Then, the "official" CyanogenMod Team is absolutely not interested in anything CM7 for "legacy" tablets now. Development of custom CM7 ROMs may be severely hindered by that problem with CWM. That is, IMHO, such a development should be conducted as a development of a matching pair of CM7/9 and CWM. A "full" Samsung Galaxy Tab (P1000) gets ICS/CM9, but it's more capable and popular Tab to get into crosshairs of CM Team. Then, its SoC has nothing to do with TI OMAP architectures.
Furthermore, getting CM7 on P1010 doesn't achieve a thing over stock Gingerbread, if you ask me. If you look for overclocked kernels that bring mostly meaningless Quadrant benchmark figures, SODs, apps crashing, shorter battery life, then go for it: you're a genuine tester.
Last, but not least, is the efforts of many good developers (fattire, dalingrin, keyodi, nemith, arcee, Samiam303 et al.) to build Ice Cream Sandwich for TI OMAP3 architecture. In their valiant attempts, they all use stock kernels so far. These might be good to support Froyo (in case of NOOK Color), they are not so good to support Gingerbread, and they prove outright inadequate for ICS. Google squarely shows that ICS starts with kernels 3.0.1...3.0.8.
Kuzma30 from Vinnitsa have started his project of building a 3.0 kernel for NOOK Tablet. He claims it boots, but so far no support for his effort is shown.
