[ROM][0.0.7.3]ICS CM9 ThinkPad Tablet (Alpha)

Koshu · Apr 3, 2012

This a a CM9 Port for the Thinkpad Tablet made by Jon2555 and me. Its still under development, so you might run into bugs.

You are flashing this ROM on your own risk. It could eat your kittens, steal your breakfast or brick your device!

(Higher Resolution)

Requirements:
- A US, UK or WE device (Might also work on others)
- root (obviously)
- CWM

Installation:
- Download xxx.zip and put it on a sd-card
- Boot into CWM (Reboot and press Vol+)
- Make a nandroid backup in CWM!
- Make sure the backup worked!
- Full Wipe (May not be needed if you come from an earlier CM9 version)
- Flash zip in CWM

Restore HC:
- Boot into CWM (Reboot and press Vol+)
- Restore old nandroid backup

Working:
- Wifi
- Touchscreen + Stylus
- Bluetooth
- HW Acceleration
- Sound
- External Mouse
- Folio (mostly)
- VPN
- Hardware Button

Not Working
- Camera
- 3G
- HW Video Decoding (i.e. for Youtube HQ)
- No mount as USB/MTP

Known Bugs
- Wifi doesn't always reconnect to networks
- Trebuchet has wrong size and misses a few pixels
- Sometimes apps on the market are incompatible (see Play Store/Market)
- Sound doesn't mute when headphones are plugged in

Play Store/Market
Sometimes the market marks apps as incompatible. This happens randomly. If it happens to you try one (or more) of the following:

http://forum.pocketables.net/showthread.php?p=80033
http://xdaforums.com/showpost.php?p=23753023&postcount=5
Search here in xda for a hacked market and install it
Reflash the whole ROM

Folio
The Folio works but some of the special keys don't. One problem with the Folio is, that there are different Keylayouts (i.e. UK, US) but without a different device ID. In the standard setup this ROM uses the UK layout, if you want to use a US layout, you have to delete a file:

Code:

su 
mount -o rw,remount /system
rm /system/usr/keychars/Vendor_1241_Product_0003_Version_0110.kcm

Thanks:
- The Cyanogenmod team
- digetx for the Green Flash fix
- Everyone releasing their source codes for other builds

First!!!!.

On a more serious note, nice to see a more organised OP for the rom. I hope we can make more progress with the development.

obscure.detour · Apr 3, 2012

I can confirm this version does fix any freezing that was happening due to the pen button bug. This version is also silky smooth thanks to Koshu's and Jon's hard work.

Also, a fix for trebuchet not displaying correctly is to use Apex Launcher

highly recommend. It has additional features as well that in my opinion make it a better experience.

yahoowizard · Apr 4, 2012

Yup, that problem was happening every 5-10 minutes, and just worked for two hours without any problem with .00731. Also, just on another note, there's that ever occurring problem of loss of pen strokes after like 5-10 minutes after which I have to replace the battery or lock/unlock the tablet before it continues to work. Is this now a hardware problem as I've had it since day 1, through all the updates and also this ROM now.

obscure.detour · Apr 4, 2012

@yahoowizard

I had that issue since day once as well, and it happened just yesterday when I restored an early build (I think it was 005x but not sure). But I feel like since 006x I haven't had that issue.

I've used build 00731 (full wipe) with Quill and Lecture Notes for several hours today without that occurring. So yeah I'm not sure what causes that bug, but like I said above, I feel like it was fixed a few builds past.

soveryevil · Apr 4, 2012

Put this on last night. Not having any market issues (any problem apps you want me to check?)

Only problem I have now is Chrome Beta still crashes after a few seconds use?

Thanks for all the hard work!

Yeah it does... and it does this on my other devices, too. Its still a beta so lets fix things with chrome when its stable or when there is nothing else to do.

with full wipe the installation takes about 15 seconds, says its complete (really skeptical here). on boot, it shows the lenovo logo but wont boot up, tried for about 20 minutes now..

//got bootloop now. so i guess i cant really say how it works for me

A lenovo boot logo? Then something went totally wrong. I replaced the boot animation, means that there are still parts of stock HC on your tpt. You might want to recheck if the zip is downloaded and moved to your sdcard without errors and try again.

pau-pau123 · Apr 4, 2012

well, the very inital font saying 'lenovo', right after the vibration.

downloaded once more, which eventually led to the bootloop (156mb).. installed on top of the no bloat ota2.5, installed full wipe, installed just witch dalvic and chace wipe. no clue what went wrong really

Ah ok that logo^^, that's normal, sorry thought you were talking about the bootanimation. Do you have an US device?

haha ye, should have put it a little clearer.

Just to make sure, did someone else try to install ICS on a tpt with OTA2.5?

I did. I got stuck on the boot animation as well, but a full wipe of things followed by a reinstall of this ROM fixed it.

Koshu,

Thanks for the excellent ROM -- after a few hurdles that were all my fault, I managed to get it up and running.

First, I'd like to say: if anyone is unable to get this running because ClockworkMod Recovery reboots itself after 30 seconds (even if you're doing nothing, e.g. sitting at the main CWM menu), chances are you installed the "ROW" (Rest of World) CWM on a non-ROW tablet. This was the case for me. HOWEVER, don't fret if you already wiped out your system -- there's a workaround.

Plug a USB device with logic (e.g. not a "dumb" battery; something like a phone or flash drive) into the full-size USB "Host" port on your thinkpad. This, magically, will prevent CWM from rebooting after 30 seconds, allowing you to properly use it for backup/restore and for flashing CM9.

In fact, this is the only difference I could find between the ROW CWM that I accidentally flashed, and the US one. So if you always will have a USB device handy of some type, you can continue to use the ROW CWM and don't have to mess with it. Plug 'er in and it magically works!

However, I am having a problem. My attachable USB folio keyboard doesn't work at all. No keyboard, no mouse, no errors. Your OP has it down as "mostly", so does that mean it only works if you do some hack, or is it just my specific model not working? I'd expect that something like a USB keyboard would be handled by upstream Linux kernel USB device drivers... no?

For posterity's sake: my TPT is the 64GB variety, with no 3G/WAN, US Version, and I installed ICS after wiping data and Dalvik, on a system that had NEVER had an OTA applied to it -- straight stock from the factory, running a ROM ending in "_0065". I was running CWM version 5.5.0.4 and tested CM9 version 0.0.7.3.1.

pen wonk - pen is periodically not recognized by the system

Unfortunately, I experienced the pen wonk periodically in class today. I wonder if it's a hardware issue too or an Android issue, because I have also experienced it on every ROM including stock. I'll try to get a logcat while note taking tomorrow to see if we can get any information about the 'pen wonk' issue.

I was running CWM version 5.5.0.4 and tested CM9 version 0.0.7.3.1.

First of all, congrats on getting up and running and figuring out that CWR workaround. I also have US, Wi-Fi only US TPT. I can successfully connect my bluetooth keyboard and even enable it as a input device within the bluetooth settings. But the keyboard isn't listed anywhere in the Language & Input settings menu. I believe it should have a new subsection name Physical Keyboard Is the keyboard folio listed?

@Koshu

I was wondering if there was a way to disable the 3G/WAN in ICS if no such connection is possible? I have a Wi-Fi only model but still have empty cell bars in my status bar. Just curious

Ok, so it already worked on similar devices. Did the installation Finish? Like allquixotic stated there reboot problems in cwm. It shouldn't reboot on it's own in the installation process.

"Mostly" Means that the Folio is working except some special keys, because there is no function to map them to in ASOP/CM9. These still need to be implemented. The rest should work out of the box. The driver folio is in the kernel, thats correct, but android still needs some mapping files to get a keyboard working. This is not the case for the mouse, which always worked if i remember correctly. Could you post a dumpsys with connected Folio?

Hm, never happened to me and I took a lot of notes with the tpt, too. Please also try to get a dmesg, because if this is happening on all roms, it could also be a problem of the kernel driver.

Jepp there is a way. It's not really disabling the 3G, more like removing the icon. But let me check if there is a way to auto detect this, because i try to avoid multiple ROM versions and I'm still planing to get 3G working.

yahoowizard · Apr 5, 2012

How do I get a logcat or a dmesg? While using some developer setting in Writepad Stylus (I think?) I noticed that the screen doesn't recognize the stylus at all at some points. It wasn't that the lines weren't registering, it was just that it was almost as though the pen was dead. But yeah, replacing battery or lock/unlocking tablet fixes it so >.> no idea what's going on there. If you fix that problem, I will love you forever, hahahaha
