Instructions

Fresh install from another rom:

Download to your external SD card

Reboot into recovery

Backup current installation

Wipe data, system, cache, dalvik cache (optional use my Blackhole scripts)

Install from zip, pick the CM9 zip

Flash gapps

Once done, wipe cache and dalvik cache again

Reboot system

Wait 10 minutes, then reboot system

Log into google and setup your device

Enjoy

Updates from my previous builds:

Backup current installation

Flash the new build zip

Clear cache

Clear dalvik

Reboot

Let settle 10 minutes

Reboot

Enjoy.

Only for updating over a previous PM CM9, not meant for flashing over any other rom, even another CM9.

Advanced update method:

Backup your current PM CM9 install you wish to update

(CWM) Go to mounts, mount /system, then go down to format /system

(CWM) wipe data

(TWRP) Go to wipe, wipe system and data

Install newer PM CM9 version

Install gapps

Go to restore, advanced restore

Restore ONLY Data

Clear cache and dalvik, fix permissions

Reboot system

Let settle 10 minutes

Enjoy

This method will clear the system partition and replace with the new system, but restores your user data, settings, apps, etc. Its IMO a cleaner upgrade method then "Dirty Flashing" straight over the previous rom. Intended ONLY for updates from a previous PC CM9, no other roms.

Current known Bugs

6-11-12, B1: You have to disable the screen off animation or your device will reset everytime you press the power button. Settings>Display> Uncheck Screen-off animation prevents it.

6-12-12, B1: Labros1995 reports rotation lock still broken.

6-16-12, NA: HDMI audio still not working, reported by pomka78

6-19-12, B7: labros1995 reports Torch Toggle does not work, volume is upside down in portrait mode (still uses landscape default layout).

6-29-12, NA: Its not really a bug, but it has come up, themes DO work, however complex themes will give a compiled error. For now, only simple color changing themes work, such as the Holo series of themes. I don't think its the ROMs fault, I think it has to do with the themes not being for Tablets. But, I added it here anyways, as a heads up.

7-1-12, B20: nickownzya reported Chrome crashes going into settings, confirmed by mapaz04. Turns out its the newest version, 18.0.1025.166 (Official Build 130050), confirmed by mapaz04. Chrome version 18.0.1025.133 does not appear to have this issue. The only fix for now, if possible, is to uninstall the update. Not possible on a freshly downloaded restore, but maybe through TiBu or whatever backup app you use. Chrome appears to otherwise function fine, just can't enter settings.

Updates:

6-13: Modified the OPs a little bit, added advanced update instructions in post 2. Added bug list location to post 1.

6-25: Added CWM Touch experimental to downloads, added some whatever info. I dare you to find it!

7-2: I've put my A100 up for sale today, but I will continue building these nightlies until the official nightlies begin rolling out, as promised.

7-2: Added a new link to the downloads section of post 1, EpicBlueCM9 theme by stetsonaw, which he confirms working for our devices!

7-4: Removed builds 1-5 as I'm sure they are no longer needed, and they were using dropbox anyways. All builds now on Dev-Host.

7-4: As the new title states, I've been working on my custom edition CM9, some build.prop tweaks, some init.d tweaks, some free apps that I generally use. It was originally going to be a pre built restore for myself, but I figured, as always, why not share it? Should be available in it's alpha form tonight or tomorrow. Still a LONG way to go on it!

7-6: The custom edition is going a little slower then I expected, hitting a couple of road blocks with the modular expansion I had in mind for running scripts, but it's getting there. cdkg has offered to test run today's alpha, so hopefully that goes well. I can't test stability since I'm constantly flashing new crap to the build, or entire new builds, that I never spend more then an hour on any flash lol. It's coming, eventually. If cdkg doesn't run into any issues I'll put up the alpha 1 build.

7-8: For those that haven't noticed, and the few still that read this section, (does anyone read here?) the custom edition is availble in the Dev section as of this morning, Aoikaze Alpha 3, please give it a whirl and report any issues you may run into, if any (because I'm perfect and all).

7-9-12: As per notsointeresting's suggestion, and a few complaints of dev-host's reliability lately, I setup androidfilehost to hold my stuff, I'll be slowly migrating everything over, then using dev-host as a mirror.

7-25-12: I'm taking a short vacation, I leave the morning of 7-26 and I'll return 7-29, I know it's a short trip, but I think I need a break for a few days. I will likely not have any kind of data up there, so I can't remote the machine to build from there, so there will be NO builds until 7-29. I also probably will fall way behind on the forums as I probably can't check in on them either, so help each other out as best you can! I wanna see peace, love and CM15 when I get back!

8-11-12: General project update. Considering my A100 bricked, I get complaints constantly about slow downloads, missing days, missing features, random broken crap that I said would happen, and other general BS that I keep getting about these builds, I'm considering stopping. I did this as a favor for everyone, it's not my job, it's not required that I do this every single day, and I DON'T GET PAID FOR THIS. So either deal with the slow hosting (it's free, want faster? It costs money) and the random broken things and odd bugs, or please stop messaging me complaining about it or I just won't build these at all, and when CM10 comes up for nightlies, I won't build them either. I'll just do my own thing, build them for myself, and laugh at people with 4 month old CM10 releases (hint, I built a CM10 an hour ago, yes I can build A100 CM10s). All this complaining REALLY makes me wonder why I'm even doing this, spending my time and money on this stuff, when it doesn't seem like it really even matters. It kinda ruins the reason I started doing this and kills my drive to even do anything for android any more, let alone the a100 or the a200. /rant

8-13/14-12 : A final general project update - I'm stopping these for awhile. You may have noticed this message already below the latest download. I'm not going to name names, just know I'm tired of the complaints and demands, if you want to demand I do something, then make it worth my while, until then deal with what I can give you when I can give it. If you aren't happy with my builds, build it yourself.
