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

could someone provide me with a working CWM download for the 64GB version, unfortunately i could not find any working link :(
[Thinkpad Tablet Android Development] explit:
What exact du you need? CWM installer for the TPT or CWM Backup?

write me an email to explit(at)gmail.com

i need to look in my collection
[Thinkpad Tablet Android Development] explit:
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
[Thinkpad Tablet Android Development] powermax928:
i still have the TP Tablet. i'm not a developer but willing to test
[Thinkpad Tablet Android Development] 5hpir3:
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.
[Thinkpad Tablet Android Development] martiniturbide:
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.
[Thinkpad Tablet Android Development] oatcooky:
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.
[Thinkpad Tablet Android Development] explit:
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.

seems any download links is broken today
[Thinkpad Tablet Android Development] Chhayank_Sharma:
Could you please send me the cwm file? I am unable to access the cwm thread. It says that i dont have permission to view that page.

[Thinkpad Tablet Android Development] Chhayank_Sharma:
or do you need some other file? like the custome recovery?
[Thinkpad Tablet Android Development] Chhayank_Sharma:
i found the recovery on a russian lenovo forum. heres the link to download it.

http://lenovo-forums.ru/Files/OS/Tablets/ThinkPadTablet/recovery.rar
[Thinkpad Tablet Android Development] bitsinfo:
thanks for your response.

i have downloaded this: https://mega.nz/file/wNRDGCbS#qys3UQsAheh19m8y0wbPLIQi-bHmJD4ovxDpfrXL7Ww

but i am stuck now! i don't know how to install it on my TPT!
[Thinkpad Tablet Android Development] Chhayank_Sharma:
so you have installed custom recovery? you need that first. then you put this file on a sd card and plug it in to the tablet. then you need to power off the tablet and thn power it on and as soon as you feel the vibration, press the volume up button. then it will boot recovery. there you have to pick flash from sd card and the locate the rom zip and choose it. do not unzip the rom.
[Thinkpad Tablet Android Development] Chhayank_Sharma:
i have sent link to the recovery. btw, the link you sent me is the link for the rom. the other link i sent is the one for the recovery
[Thinkpad Tablet Android Development] Chhayank_Sharma:
here is link to forrum where i found the recovery file. its in russian so you will have to translate to english. follow the instructions here before you flash the rom.

Lenovo Thinkpad Tablet Finally Rooted - Here's How To Do It, And Install ClockworkMod Recovery

www.androidpolice.com
[Thinkpad Tablet Android Development] Chhayank_Sharma:
you can find adb drivers here

Universal ADB Drivers
[Thinkpad Tablet Android Development] Chhayank_Sharma:
you do not need to search for the adb tool. after you download and extract the root exploit zip, the adb tool will be in the folder where you extracted. you just need to type cmd in the area in windows explorer where you see the file path and it will open command prompt there. then you follow the instructions to install custom recovery after rooting.
[Thinkpad Tablet Android Development] bitsinfo:
Hi there,

thanks for your follow up..

i have done everything and my TPT has been successfully upgraded to 4.1.2

it did not boot at first, but after 2 times reboot it could complete the boot successfully.

The problem now is that Google Play shows very old version and i cannot install any app! Eventually, there's no benefit from upgrade so far for me :(

is there a way also to retrieve the original Note App?
[Thinkpad Tablet Android Development] bitsinfo:
I'm glad to inform you that i have solved the issue in following steps:

1- downloaded Google Play apk from here :https://www.apkmirror.com/apk/googl...2-19-all-0-pr-229493918-android-apk-download/

2- using adb, i have forced install the above apk:

adb install -r googleplay.apk

Now, my TPT is live again :)
[Thinkpad Tablet Android Development] Chhayank_Sharma:
nice. btw you might not be able to use youtube on it though. i have installed the latest version of youtube that works on android 4.1 on my tpt and it keeps showing server problem.
[Thinkpad Tablet Android Development] bitsinfo:
Yes, YouTube is not working :(

but have you restored the original Note app ? It is really nice and professional!
[Thinkpad Tablet Android Development] Chhayank_Sharma:
Im sorry i dont have the note app. try to find the apk of the note app.I will tell you if i find it.
[Thinkpad Tablet Android Development] Chhayank_Sharma:

I was running v01 and flash v05 yesterday and am amazed buy what you did, Koshu you made my tablet faster and the screen lock is actually responsive, Thank you
[Thinkpad Tablet Android Development] crabnebula:
Koshu:

Wow ^ 10

Thank you so much for this. I feel liberated. :)
[Thinkpad Tablet Android Development] froader:
I am aware that /data/media is mapped as /sdcard0 which is internal storage. Its exactly the same way on my Galaxy Nexus.

CWM leaves this folder alone. It doesn't backup, nor wipe.

This way makes much more sense yo me. Imagine backing up 16/32/64GB of data, then wiping it each time you flash a ROM. IMHO that's unnecessary and awkward. I would prefer this directory be left intact.

I am wondering what the differences in the script for CWM on the GNex vs yours.

Or, maybe you have a good reason I'm not thinking of for doing it this way. Just trying to be constructive and definitely thankful that I can finally use my tablet.
[Thinkpad Tablet Android Development] Koshu:
It's just that i tried do get clockworkmod working as fast as possible and then went over to work on CM10. But in the meantime i already released CWM 0.4 that won't touch the internal sdcard anymore.
[Thinkpad Tablet Android Development] froader:
Hey, no problem, I certainly appreciate it, and that was quick to push out an update. This will be very helpfull. THANKS

Edit: flash and tested backup, which is SO much faster now that it IS leaving internal storage out of the loop. Sweet!
[Thinkpad Tablet Android Development] Apfelschale:
Here's a strange thing: Camera worked, at first. After I switched to frontside it crashed (fc gallery) and keeps crashing everytime I open the camera app (even after reboot). Third party camera apps work though.

Also, maps sometimes sends me back to the homescreen but without crashing.

Everything else seems to work for me (besides the listed bugs), at least from what I can tell.
[Thinkpad Tablet Android Development] madamada31:
bug

found bug just now.. tried to share internet from my iphone through bluetooth and as soon as they connected the tablet rebooted.. when it came back on it connected to the phone but no internet connection.. tried to turn it off and back on again and it worn't turn on.. restart the tablet and it started to turn on and off like normal.. tried to connect to the phone and it restarted..
[Thinkpad Tablet Android Development] chuinkee:
ROW 64GB with 3G reporting in from Malaysia. PID 1838-A26, not sure if it is Gobi or Ericsson card.

Thanks Koshu for the great work. I was on OTA3 and decided to give CWM and JB v0.4 a go. here are my observations:

- video playback is much smoother comparing to that in ICS. nice work!!!

- 3G works in this part of the world. Only cosmetic issue is that instead of showing the carrier hame (e.g. My Maxis) it shows "no services".

- Google maps experience constant crash. I have seen this issue back in GB but it was resolved in ICS. Not sure why it resurface in JB.

- I normally switch off my TPT at night. everytime I turn it back on the next morning I keep getting the message "unfortunately the process com.android.phone has stopped" for the next 2 minutes before it stopped. I can't seem to find the process in the app list to freeze it. anyone seeing this message as well?

will report in again if I notice anything else.

thanks

Ben
[Thinkpad Tablet Android Development] dsw1ft:
I think Koshu fixed the cell phone problem with 0.5, but you have to wait until he releases the .zip for your 3g cards.
[Thinkpad Tablet Android Development] chuinkee:
Is there anyway to find out the 3G card make without opening up the tablet?
[Thinkpad Tablet Android Development] Koshu:
Confirmed (The front camera worked already, looks like i broke something in the new version)

Confirmed using a galaxy nexus

Confirmed google maps crash, carrier is displayed correctly on my device :confused:

Can you send me the output of "adb logcat -b radio" ? Reboot first and make the logcat directly after you connected to 3G.

There a no big fixes in 0.5. The main reason for 0.5 is to split the rom to better fit the different devices.

Yes, try the command "lsusb" (in terminal or adb) it will print some numbers like this:

shell@android:/ $ lsusb
Bus 001 Device 001: ID 1d6b:0002
Bus 002 Device 001: ID 1d6b:0002
Bus 001 Device 002: ID 0bdb:1924

You can look up these numbers. Exe557 has gathered some in this post. In my example it's the 0bdb:1924 line that matches the Ericsson F5521gw.

To All:

Will try to fix some of the bugs while i wait for the gobi card to arrive and as soon as i can find some time.

Edit:

Uploaded 3G patch for version 0.5. Read the new installation instructions.
[Thinkpad Tablet Android Development] chuinkee:
thanks for the info. looks like i am using a ericsson card.

btw, any foreseeable fix for google map?

i understand gps is not exactly working now. it was working quite well in ics, locking in mere 30 sec. for JB the gps test app shows the gps can detect only up to 2 satellite and thats it. any idea what is the reason behind?

thanks.
[Thinkpad Tablet Android Development] Magnusmarshall:
This is painful .

All this development and i can't touch it since my thinkpad was sent with ics already on it.

The pain the pain. :(
[Thinkpad Tablet Android Development] Apfelschale:
Another minor bug I experienced on my TPT WE 16GB Wifi Only: After some time in sleep mode wifi doesn't work (won't load any data). Have to turn it off/on again.
[Thinkpad Tablet Android Development] chuinkee:
Hi Koshu,

refering to your request"Can you send me the output of "adb logcat -b radio" ?"

attached please find the output of the logcat "radio.txt". it took almost 10 minutes of repeated message "unfortunately the process com.android.phone has stopped" message before it makes connection to 3G. even then, the carrier name still does not shows up. In its place is "no service" but the 3G connection works.

The same sim card was working in ICS, still I swapped with my other data sim card and the same issue still occurs. could this be a driver issue with the ericsson card?

thanks

Ben

*edit 20120903: I updated the radio.txt logcat file. this file contains entry from the time it was retrying to connect to 3G until it eventually succeed in doing so.
[Thinkpad Tablet Android Development] bigsnack:
Digitizer support is fully working on this, correct?
[Thinkpad Tablet Android Development] camou23:
yeah!
[Thinkpad Tablet Android Development] obscure.detour:
This could potentially be a kernel/driver issue due to Lenovo. I had that issue with every stock version including ICS so it doesn't surprise me that this might exist. Typically, in the past all I had to do is just go into WiFi settings and reconnect and it works, and on rare occasions turn WiFI on/off. Maybe Koshu could shed more light on the issue.
[Thinkpad Tablet Android Development] Koshu:
Already working on it. I'm just a bit short of time at the moment.

See above.

Forgot to add this to the working list, will fix it right away.

I can't tell for sure, but it happens in some combinations of tpt and wlan router. I had this issue only in the wlan of a friend of mine (with stock ROM). This might be caused by the driver or some faulty default settings. Luckily the drivers are open source, there might be a chance to fix it but it will be hard to debug, because on the one hand, my own wlan works fine and on the other hand, even if it wouldn't work correctly it always takes some time until the bug occurs. If you want you could help by trying to get a logcat and a dmesg of the moment the bug occurs (you need to run both in adb and write it to a file, the output on the screen most likely won't be enough because it shows only the last lines)
[Thinkpad Tablet Android Development] chuinkee:
Thanks Koshu, no rush.

you got my transfer yesterday?

[Thinkpad Tablet Android Development] Vito Andolini Corleone:
Hey guys,

I have an unrooted ROW thinkpad upgraded to ICS. My TPT hasn't gone through the 3.5 OTA update. It would be great if someone could give me step my step instructions on how to get my TPT rooted and start running the new Jellybean ROM. Please note that I use Mac OSX. Thanks in advance!

Cheers,

Vito
[Thinkpad Tablet Android Development] danjac:
If at all possible to root ics, I would suggest to look here: general section -> ics root (there seems to be a way for some).

@ Koshu: Thanks a lot for your work and the new rom - seems to be the best, that has ever been running on my tpt.
[Thinkpad Tablet Android Development] quyTam:
Hello,

I've got 2 reboots without using bluetooth. Will try to get logs.

Otherwise, anyone noticed a problem with some big games? Like "Blood & Glory" or "Dead Trigger", the touchscreen is no more reactive (except for the system bar)
[Thinkpad Tablet Android Development] shrinex:
^I experience the same issue. Haven't found a way to get around it/fix it.

Side note: I've noticed that in the "not working" listing, the auto-rotate key says to not be working. Mines works fine, soft and hard keys.

Just thought I'd put that out there.

Thank you for the fantastic release!
[Thinkpad Tablet Android Development] rekuhs:
Forget all this - I did a restore and then re-flashed CM10 and the 3G patch and it's worked fine.

Hey, it's me from over in the recovery thread - got all of those issues sorted.

Now I have a new one.

I've successfully flashed CM10 but I can't flash the 3G fix, I just get this:

set_perm: some changes failed

E:Error in /sdcard/Download/tpt-cm10-3gpatch-0.5.zip

(status 7)

Installation aborted.

Everything I've found about my tablet suggests that it has the Ericsson modem, including the lsusb thing, '0bdb:1924 = Ericsson F5521gw'. Could that all be wrong or is it likely to be something else?
[Thinkpad Tablet Android Development] camou23:
@Koshu

Has the Official OTA 3.5 a new Kernel?

And are you using the newest?
[Thinkpad Tablet Android Development] daswahnsinn:
I would like to see the My Script notes on the next build, I like using that and quill for class. I tried to install it but I can't figure out how to convert the .apk and libs from p files.
[Thinkpad Tablet Android Development] Koshu:
Yes, thank you very much.

For some reason it isn't working on my device, this is still a wip but it seems to work already for some.

Maybe the assert check again. Try the zip attached to this post.

This rom includes the OTA 3.5 kernel which is 2.6.39-4.

Try to get them out of a nandroid backup then you can get the apk directly. The p files are only patches and not a complete app (if my guess is right and you looked into the official update packages).
[Thinkpad Tablet Android Development] daswahnsinn:
I don't have a nandroid backup anymore. I just looked and it's not there, I did one for ICS before I flashed CM10. So I guess I'm not doing that. Oh well, I keep trying to port stuff and do some trial/error stuff. Thanks Koshu
[Thinkpad Tablet Android Development] darkhandsome18:
Hey Koshu, Please I keep forgetting, does the UK thinkpad use an Ericsson or Gobi Card. In order words, since only the Ericsson card works on this rom, can I use 3g on my UK thinkpad with it?
[Thinkpad Tablet Android Development] Koshu:
I'm not 100% sure please, which card is build into UK devices. Look at the end of this post to find out: http://xdaforums.com/showpost.php?p=30985558&postcount=91

@all:

A little status report: Fixed the front cam and some other minor bugs. Still looking for a solution to fix google maps.
[Thinkpad Tablet Android Development] darkhandsome18:
Checked on my tablet. I got the 1924 which means its the Ericsson. So for any uk tpt guys it means we can use 3g on this rom since the Ericsson card works.

@Koshu good job on fixing those bugs. I tried to sell off this tab but its not even worth anything now (someone offered me 100 pounds for mine lol that's what the keyboard alone costs) so I'm just gonna give it to a relative so I figure its better to give it away on this rom than restore to stock. Are going to see an update soon? not asking for ETA here, flamers just that I'm sending it out next week so an update would be nice to put the tab in the best shape possible to the person I'm sending to. Not that the tab isn't running brilliantly already - Your work on this rom's development puts lenovo and their software department to shame.
[Thinkpad Tablet Android Development] rekuhs:
Ok, new issue.

Everything flashes fine but 3G only connects when connected to a wifi network, as soon as wifi disconnects, so does the 3G.

When they're both connected, it shows me the wifi network name as well as my carrier name.
[Thinkpad Tablet Android Development] quyTam:
Just a little question, I don't know if it's JB, CM10 or from this rom, but I don't see "Picasa web album" in the synchronisation menu.

So there's no picasa album in the gallery...
[Thinkpad Tablet Android Development] Koshu:
I think i will release a new version this weekend. Still hopping i find a fix for google maps

Does this happen when you leave your wlan area or when you disable it manually (or both)?

Hm the gallery app seems indeed a little weird. The option tap is complete empty... will use a differnt one for the next release.
[Thinkpad Tablet Android Development] rekuhs:
Both mate, I was using the hotspot on my phone so it does it either when I turn off the hotspot or turn wifi off on the tpt.
[Thinkpad Tablet Android Development] shrinex:
HDMI-out

I've noticed that HDMI is not in either the working or not working list, so i thought I'd try it...

...it doesn't work...

time to toss this into the "not working" list :)
[Thinkpad Tablet Android Development] daswahnsinn:
Do you think we could test out trying to get an app (Snotes) ported from the galaxy note 10.1 to work on this ROM? I think it would be a great addition to what we have now.
[Thinkpad Tablet Android Development] Koshu:
Can't reproduce this bug. Can you make a logcat while turning off wlan? Has someone else this problem?

Will add it ;)

Pull the apk from a galaxy dump and try it. The stylus interface is standardized since ICS (which doesn't guarantee that lenovo and/or samsung didn't make their own interface). I think there is round about a 20% chance that it will work out of the box.
[Thinkpad Tablet Android Development] madamada31:
The auto-rotate button works on 0.5 but not on the earlier builds of cm10.
[Thinkpad Tablet Android Development] DiJu519:
I'll personally have to wait for the pen only mode to be implemented. Big feature for my schooling.

Keep up the good work.
[Thinkpad Tablet Android Development] Koshu:
Version 0.6 out. No real big changes, only some bugfixes.
[Thinkpad Tablet Android Development] mandrsn1:
Awesome. Thanks for the update.

Random question: How hard would it be to get integrated OTA Update Center support? It seems like an easy way for users to check for updates for the ROM.
[Thinkpad Tablet Android Development] chuinkee:
Hi,

I have tried out 0.6, the 3G issue I reported earlier is still there.

thanks
