Hi

I'm also hoping to find a way for Koshu or other developer to get motivated to create a newer ROM for this tablet.
There are several tablets that uses the same NVidia Tegra 2 250 - T20 processor that has newer custom ROMs and TWRP 3.0 installed. I know it is not the same but I think it can be useful for the developer to see some similar CPU projects to have some better starting point.

I will keep hoping and if there is something that can be done to help let me know.

Regards

I miss my TP tablet w/it's multiplicity of ports and connection options. One of the last pieces of hardware Lenovo produced that still had a modicum of IBM upstate NY mojo.

Well. I think i will try tu build something newer for the ThinkPad Tablet.
I'm not a developer, only advanced user.
My wish would be to try SailfishOS on the TPT, but this is only a dream.... But lets see... Maybe there will come something out. Everybody, who want join the project or help me with building - is very welcome

Is someone still using the TPT? I lately pulled it out of a drawer and it still works but I get segfaults like crazy when using youtube or any kind of browser beside the standard browser... so chrome, firefox or opera are not working.
It is quite interessting that chrome will not start at all, firefox gives an error that armeabi v7a is not supported and chrome will show a blank screen and crash then...
I tested Firefox 42 which works but playing videos in the browser does not work... I can post the segfaults here if someone has some clues how to get rid of them.

It would be more crazy to run Zircon kernel on that tablet and make Fuchsia work :D

Good look there. Please post back any progress.

Firefox 52.0.2 is the last version that works on the TPT. The others fail with that armv7-abi error. Can't believe mine is almost 7 years old now, it's still a capable device for web surfing and reading ebooks. The Ntrig digitizer also works with the latest Surface Pro pens.

Someone need to start to deal with it. Kernel and driver sources are FOSS and can be downloaded on Lenovo Website, so everybody who want to build something newer - can try it, but with every day this beatyfull peace of hardware is getting older and older and that is the main problem, why there is so small interest in building something newer....

For anyone wanting to develop for this device.. be careful when you issue a format or factory reset. You have a chance of bricking the emmc, which you may not be able to recover from.

It's jelly time. Made by a TPT user for TPT users.

Notice
  • Developed on a WE/16Gb 3G TPT. US, UK and ROW Tablets (any size) are confirmed to work, too
  • Density set to 160 dpi to keep market compatibility. Don't like to do this but the market problems are just annoying. Change it with a appropriate app if you don't like it (btw. our native density is approximate 150 dpi).
  • Flash on your own risk! Might turn your TPT into a expensive chopping board.

Requirements
  • This build uses the Lenovo ICS kernel, you need to upgrade to stock ICS first (Make sure you keep root!)
  • A ICS ClockworkMod version like this one. :D

Screenshots
  • here (Thanks obscure.detour)

Installation
  • Download ROM zipfile (and 3G patch if you want to) 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 CM10 version)
  • Flash zip in CWM
  • Optional: Flash 3G patch in CWM
  • reboot

Restore Stock ICS
  • Boot into CWM (Reboot and press Vol+)
  • Restore old nandroid backup

Additional Steps

Working:
  • Wifi
  • Touchscreen + Stylus
  • Bluetooth
  • HW Graphic Acceleration
  • Sound (Including Mic)
  • Cameras Front/Back
  • Compass (but needs calibration)
  • HW Video encoding/decoding (i.e. for Youtube HQ)
  • Mount as USB/MTP for filetransfer (in windows)
  • GPS (Well "working" like always nearly unusable but its working theoretically)
  • Lightsensor and other sensors
  • 3G (Ericsson card)
  • 3G (Gobi card)
  • HDMI
  • Stylus
  • Buttons

Not Working
  • Nothing here anymore. Everything is working somehow but some parts still contain bugs (see buglist)

Known Bugs
  • Google maps crashes sometimes
  • 3G issues:
    - On some devices the carrier is not shown and 3G needs more time to connect
  • Wifi tethering not working
  • Stylus only mod not changeable in lockscreen
  • Some other bugs that occur only on few devices

Things maybe added in future releases
  • A density of 150dpi (a soon as i find a good hacked market or something else)
  • Getting everything to work and stable

Thanks
  • The Cyanogenmod team
  • Everyone releasing their source codes for other builds
  • Everyone trying to find and report bugs
  • pwstein for lending me his gobi card

If you like this ROM press the donate button and smash your hand on the NumPad :fingers-crossed:

@jk7gr and anyone else still using a TPT

This project has been deprecated but the ROM and recovery are functional as is.

Koshu still gets full credits - I've just re-upped the relevant files to Mega.

ROM version 0.9.2
3G modem patch
CWM recovery
format data partition

Instructions to flash recovery are on this post
Enter recovery by rebooting while holding Vol+
Flash ROM and patch together in CWM
Optional: Flash format-data in CWM if not booting properly

Could you please reupload the files? When i tried to open the cwm recovery file, it said file is no longer available.

    Koshu, are there any plans on going further? I've noticed another bug connected with camera app (I guess, cause camera is still missing).
    I can't set my own wallpaper, gallery just can't resize it. I think thhis bug is in gallery app, and it is connected with camera app, so... waiting for update.

    I haven't abandonment this project, but i'm doing this in my free time and i don't have much at the moment. I'm working on integrating a self compiled kernel right now and setting up the sources on github. A new version will most likely released this or next weekend.

    I wonder if this hotword detection issue is something to be reported to the app devs or if its something we could find a workaround for.

    Edit: Interestingly, it works with hotword detection on while playing music.....as soon as i pause the music, it crashes. With or without headphones.

    Eh ... what? While playing music... oh boy, i'm already totaly excited to search for this hotword bug :/ (well it never happend here, anyone from germany with google now-hotword crashes?)

    At the moment only bluetooth is working (or was the last time i tried ;). Well these things are more complicated then it sound, so not sure when i have enough time for that.

    Besides the problem of no touch input in games that obscure.detour already mentioned, this works brilliantly. Many thanks for your hard work on it!

    Fear not little gamer! Version 0.9.1 comes to the rescue! ... well i hope. I spend the day reading the source codes of xbmc/android i found something little interesting. First it uses some kind of native cpp api instead of the java api (well that's not really surprising). Second: To determine the type of an input (is it a button, is it the touchscreen?) it looks at the class/source mask and compares it to an constant value. This value is i.e. 0x1002 for touchscreens and 0x4002 for stylus devices or to be more exact its 0x5002 for stylus devices because its also a touch device (0x1002 and 0x4002 combined bitwise). Now there are to problems: First for some reason the android system recognizes both our input devices (Mutlitouchscreen and sytlus) as input devices with a stylus and gives them the number 0x5002. Second: xbmc doesn't check if a device is able to send touch events, so if the class/source code contains(!) 0x1002 but if its only a touchdevice, so the class code needs to be exactly 0x1002. That's not really the correct way of doing things, i think it happened because there are only a few tablets with stylus on the market.
    I fixed this in version 0.9.1 by setting our touchscreen to 0x1002. Now the touchscreen works in xbmc and in DeadZone (free version) and if we are all lucky that's the case for the other games, too. However this also mean that the stylus won't work in these games unless the developer change their way of determining the source of an input event.

    Let me know how it works. If you find a (free if possible) game/app that still won't do anything let me know that, too.

    P.S: Oh and i fixed the stylus only mode.

    P.S.S: The 3G patch is the same as in version 0.9. I only renamed it to prevent confusion. It should still work properly, because i didn't update the sources but tell me if i'm wrong and i will fix it.

    Well i'm using the CM10 Sources fetched direktly from the cyanogenmod git with all its pros and cons. With that said you can expect 4.1.2 for the next release, but without the OC kernel (have to rebuild it first), so hopefully it's a "stable" release again. Not much other changes yet beside the new stylus only mode and 4.1.2. If there are no big complications with the new sources i might manage to release it even this weekend.

    Ok here it is. I used this for quite some time (just had no time to upload it) and it worked without any big problems in my use-cases, that doesn't mean that there are no major bugs as i didn't try all the thing i normally don't use my tpt for. For that reason I left the download links for 0.8.1 untouched, so you can revert back to the older release in case that something isn't working like you expected, because it might take some time before i can kill the bugs again.

    There are two major changes:
    1. Switched to the CM10 Stable branch
    2. Added a selfcompiled kernel with newer wifi drivers (intentionally to fix the wifi SOD problem, that didn't work, but hadn't any problem with the new drivers either)
