[Nexus 7 Android Development] machmanx:
Figuring out the install

Story: So I wanted to try out lollipop and move away from Autodroid because Google maps was continuously crashing on me and I assumed it may be because the current version doesn't like KitKat anymore (could still hold true as I haven't tested it in KitKat yet). But after updating to the Oxydo-revamp and Optipop, the USB audio would not kick in unless I left it plugged my car over some unknown period of time. Besides that, the tablet wasn't charging. So gave up after trying to mess with it and came back to Autodroid.

Problem was that I too ran into the same Slimkat logo blinking issue where the OS would not load. That's when I thought, "Ok, looks like users are having issues like this since it happened to me now". So I played around with installing this multiple ways using TWRP (used 2.8.3.0 like a few recommended, though I don't know if that helps or not). I was also experimenting with FS2S. So this is what I found out:

-When installing Autodroid using TWRP, just because TWRP reports that it was a successful install DOESN'T MEAN it was successful.

What I mean is this: try booting into TWRP recovery and use the Install option. Choose the Autodroid zip file and start the install. Now READ the messages being shown on the screen, and I mean READ EVERY LINE EXCEPT for the text-generated logo...you can skip that part. Right after the logo at some point I found this message:

Unsupported partition layout found :eek:​

followed by

No changes were done to the device, exiting. :p​

AND THEN, later it also reported

Script Succeeded: result was [0.100000] :confused:​

Which, subsequently made TWRP report a success as well. See???

For me I had all partitions set to FS2S and that was the issue. Even though in the beginning it reports to support "ALL-FS2S", that's simply not the case, or somehow the latest build broke that. Maybe a dirty flash might solve the problem, but there's an easier way. Either format all your partitions to EXT4.....OR....format ONLY DATA partition to FS2S and keep the cache and system as EXT4. The Autodroid installer is OK with, and will recognize the data partition as FS2S and allow the install. This time you get the right messages:

Setting the right partition layout.

Data-FS2S partition layout found. :good:

Boot.img flashed. :good:​

and the same damn message whether it failed or succeeded

Script Succeeded: result was [0.100000] :confused:​

So there you have it, the safest way is to use all EXT4 but as you may have heard, you may suffer NAND performance issues. Just set Data to FS2S and leave the system and cache as EXT4 and you'll be fine.

PS: Before doing all the above, you may want to flash the stock 4.4.4 image using the Nexus Root toolkit. Other noted things:

-I tried changing the cache to FS2S after install. Autodroid didn't like it and hung at the Slimkat logo screen. (Don't do it.)

-The "Flash Zips" option in the advanced section of the Nexus Root toolkit MAY NOT actually flash the zip package when it enters recovery mode, lol (Yeah, it's not really funny when it fails but funny because some users like myself auto-assumed that the toolkit would take care of everything while I sit back and relax) It's better to manually flash the ROM image with the Install option in the TWRP recovery program.

Lesson of the moment: Read Those Messages!!!

Edit 1: BTW, if you run into a "Type Password To Decrypt Storage..." issue, then it means that you can't use F2FS for some unknown reason. I had that issue and could only get that message to go away by formatting the data partition in TWRP, aka the format option. It changed it back to EXT4 and all is good. I just can't use F2FS... :(

Edit 2: HOLY! I got it to install with ALL-F2FS! I dunno how but the ROM boots and all! I'm going to try to figure out why.

Hope this helps someone. . . . anyone? Yoohoo? Hello??? Are you still there? Sleep mode Activated....
