So from now on we will be able to flash future updates through recovery without wiping everything?

Exactly, future updates will be CWM flashable .zip's.

All, I just noticed that Google Chrome isn't showing in the market, but Maps is. I swear it was showing up when I was testing previously. Will have to investigate...

I dont know if it's me or because of the ROM. WIth the rooted ROM before AOSP, I was able to install Chrome with a APK downloaded from mobilism but sometimes the pages are fine then just rendered white , for all tabs.

Does anybody use SKYPE ? When I do video chat, my broadcast picture stretched vertically when I broadcast-only (no picture feed from the other side), the picture my friend saw is fine though.

Many thanks for your hard work.

That is the main thing that i hate about Lenovo's Factory ICS image, i still cant install Chrome or Evernote, or many of my NEEDED apps. I hope that you get this working soon. or at least a temp fix.

 

[Dueces99]

Just flashed the rooted aosp, the boot animation is a nice touch. The app compatibility issue seems fully resolved outside of Chrome, pointed out already, which is no biggie for me atleast. I still can sideload Chrome and runs perfectly. Also, so far the dictionary miss-spell issue doesnt seem to be a problem anymore. Maybe its just me but touch responsiveness seems a little better/quicker with this build. Just tried using the command 'k1recovery' to boot into recovery and it keeps giving me an error relating to permissions, saying it cant create /dev/block/mmcblk0p5. Seems like I just need to change the permissions of the /block folder but wasnt sure if I was just not doing something right.

Massive improvements from Lenovo's vanilla ICS still, thanx khanning!

Noticed some graphical glitches. Screen goes black if switching orientations on lockscreen and home screen.

@Khanning88 Can you provide a mirror please? Goo.im is down and shows "Internal server error".

Never mind. It's up again.

Yup the screen flashes when switching orientations, for a split second...

 

[john9]

That's great. thanks for share.

 

[Hetalk]

Flashed this one and works wonderful.
Rebooting to recovery didn't work 1st, but then mounted filesystem as rw and tried the command and could get to recovery.
Got an error "Can't mount backup path" when trying to make a backup. Is it because I didn't have an external sd card.
If yes, is there a way to take a nandroid backup to internal memory?

BTW, thanks again for providing this ROM.

 

[erickwan]

Thanks khanning88 for giving this fabulous AOSP ROM

Does this ROM support the Wifi+3G version?

 

[leo_bsb]

I found some issues installing apps, including some games, Zinio magazine reader, google earth, etc, all saying incompatible with my device.

 

[Burlito]

I experienced alot of freezes while restoring my backup with titanium backup.
I keep testing if it also occurs in normal use.

 

[Cybie257]

Installed AOSP-Rooted. So far, Chrome (already noted as issue in OP), and POGO Games showing up as Incompatible.

Other than that, and possible other apps being incompatible, looks great and installed as easy as can be.

Thanks Khanning!

we need an easy way to enter recovery. Rom Manager button doesn't work.
Reboot recovery from terminal emulator doesn't work either.
Could you implement the nice options when turning the unit off?

 

[Burlito]

several more freezes. obviously not depending on any special app..

 

[khanning88]

Does this ROM support the Wifi+3G version?

I'm not sure if 3G works since I have a Wifi version, but if someone with a 3G version could meet me in freenode IRC room #ideapad-k1 I would be happy to work on it. If you aren't familiar with IRC just go to this link and join the chat.

From a terminal app type:

su
k1recovery

Or from adb type:

adb shell k1recovery

Either method will reboot the device into recovery. I will work on adding the power menu options later.

several more freezes. obviously not depending on any special app..

I haven't experienced any "freezes" but when it happens to you could you please document what you were doing and take a logcat to help debug.

[Cybie257]

Here is a very simple way to reboot into khanning's CWM recovery.

1. Playstore --> Download/Install aShell app
2. Run App
3. Select Checkbox for "Root" (In Settings, you can set app to start Root as Default)
4. type "k1recovery" into textbox
5. press "start command" button.

Simple, no need to be in "true shell" mode. This app allows you to run shell commands without the terminal. Great for newbies, quicker for anyone.

Hope this helps!

Here is a quick fix for the hardware keys. Just flash the .zip file from recovery. Updated first post with more detailed booting into recovery instructions.
