I should have clarified... I am using Krook's CM10, which is 4.1.2. While not cutting edge, it has been pretty reliable and most everything works correctly. It also overclocks to 1.4GHz on my K1. My AnTuTU score is 9278 (tested today).... which is obviously modestly slower but then again, my bluetooth works, and so does the headphone/mic jack, ... I use GrooveIP a lot with the combo earbud/mic from my Galaxy S3... they work very well. I haven't played around with optimizing any of the governor settings or memory tweaks, so maybe I could up my score a bit...
[Thinkpad Tablet Android Development] wmarcin:
So my K1 has become more and more sluggish over time (I'm on the latest 4.2.2 nightly). I installed xposed and Greenify, and a couple other useful modules, and this thing now flies!

I haven't seen anyone mention xposed in this thread, so I just wanted to let you all know that it installed and is working great for me.

... Moto X VZW DE ...
[Thinkpad Tablet Android Development] K1Andy:
I can see how Greenify would improve performance, especially right after turning on, unlocking, or connecting to WiFi, but I'm not clear on what Xposed would do to help performance (although, I guess it depends what modules you install). Can you say a bit more about what you did?
[Thinkpad Tablet Android Development] wmarcin:
That's exactly it: Greenify running on xposed framework allowed me to greenify a ton of apps that normally run in the background. This made my tablet a lot more responsive. I also have Boot Manager, YouTube Adaway, MinMin Guard, and Crappalinks modules installed - I don't think they affect performance, though.

I really only posted to let everyone know that I successfully installed xposed on this tablet + CM ROM, since I didn't see it previously reported.

... Moto X VZW DE ...
[Thinkpad Tablet Android Development] K1Andy:
Yes, thanks very much for the information. I see now that the donate version of Greenify, in conjunction with Xposed, does provide additional hibernate control over system apps. Also good to know that Xposed works well in general - just installed the framework and some of the modules, and it really does help, plus provides a number of nice options. :good:

hi guys... is this thread still active?

i have a problem with my k1 here :(

currently i run cm 10.1 on my k1, but 2 days ago, it stucked on lenovo start screen...

i try to re-flash again with the same rom, but it does't work..

i tried to re-flash with others rom, but still doesn't work...

now, the nightmare is comin worse, when i try to re-flash, this message pop in :

bootloader status: specified partition is invalid or does not exist (code: 7) me

ssage: nverror:0x42008 (0x6042008) flags: 0

i try to lookin for solving this probs, but i can't find any solution...

please help me :(

fyi, i already try to re-flash to stocked rom (honeycomb), but the message still the same..

bootloader status: specified partition is invalid or does not exist (code: 7) me

ssage: nverror:0x42008 (0x6042008) flags: 0

help :( :(
[Thinkpad Tablet Android Development] kaschemme:
Hey,

you got the same issue/bug like me. I think something with the storage causes the problem. I tried all my roms and finally, a very old honeyc. rom works. But this was a long time ago. If I find it, I'll send you the link. but don't wait too long of my answer. The result of this old rom was, a very slow K1. I still have it but I don't use it.

Sorry, but you will look for a new one :(

kaschemme
[Thinkpad Tablet Android Development] :
I believe it's because of the internal storage corruption. My K1 had the same issue and same result of bootloader error and I wasn't able to revive my device. I even tried researching and asking in this thread but nothing really works. That was heart breaking as I just had my device for about a year.

Anyway, just still give it a try if you find a stock HC.
[Thinkpad Tablet Android Development] Kosten:
Hi, Кaschemme!

I'll try to rebuild cyanogen for k1 and use youre repo at https://github.com/kaschemme. Is this repo in actual state?

Is there a fundamental opportunity to build CM12 for k1?

bake mainboard in oven 200 C for 10 minutes and then re flash with stock HCS.....

I can't flash this anymore, there is something wrong with my K1. Only original Android 3.x is running on the tab ?

sorry for bumping this old thread but does anyone have a link for the nvflash wifi only version of this rom? the OP links are all dead. Help is appreciated.
[Thinkpad Tablet Android Development] Grobie13:
It's been a while since the last post... But in the post before yours, my last one, there's still a working link. Is that what you are looking for? If not, sorry I have no Idea anymore what is all needed for correct flashing this thing, but there are several files sleeping on my NAS, perhaps I could provide the one you are searching for...

Has anyone here got the still active link for CM10.2 (Android 4.3) by Kaschemme
[Thinkpad Tablet Android Development] :
Bummer mate! I just deleted mibe a few days ago. Sorry for that.
[Thinkpad Tablet Android Development] mujumj:
Oh So close... yet so far... :(

Now that I know someone is around these posts...

I manage the 4.0.3 version after hours of googling. The thing is GAPPS and Playstore arent there. I tried several version of playstore apk, but they get installed... but not open.

Also, looking for a CWM/TWRP recovery image as well for the Lenovo K1...
[Thinkpad Tablet Android Development] :
Remember that version. You have to dig in to the old threads which version of playstore apk will work. Goodluck dude!
[Thinkpad Tablet Android Development] jmturner:
Anyone want to get LineageOS working on the K1?

I'd love to dust off my K1 and put a fresh copy of CM/LineageOS on it. Anyone want to work on this with me?
[Thinkpad Tablet Android Development] user20211:
I am currently running khanning's aosp 4.1.1. I don't know if the file you linked in your last post would work if I update via the recovery menu from an SD card. Would I still need to find the correct version of gapps? Thank you for your help.

---------- Post added at 05:25 PM ---------- Previous post was at 05:17 PM ----------

I didn't know there was an android 4.3 released by Kaschemme! Does anyone has it running on their K1? Could you provide a link to a post?
[Thinkpad Tablet Android Development] mujumj:
It is mentioned in this thread as well, about the 4.3 ported rom. But all the links are dead... :(

If jmturner can port the CM/Lineage, that'd be just awesome :)

---------- Post added at 06:22 AM ---------- Previous post was at 06:19 AM ----------

Have you started on this ?

Though a programmer by profession, I'm a noob in Android coding...
[Thinkpad Tablet Android Development] Grobie13:
Sorry, I had some problems with my NAS last weekend. I hope they were ironed out now. I saw different files for the K1 on still NAS, including recovery and gapps. I'll upload everything this evening, if I find some spare time...

[Thinkpad Tablet Android Development] mujumj:
Eagerly waiting for your post, Grobie13...

Meanwhile, when I was googling around, found this site, where it was mentioned Android Nougat ported for K1 !!!

At first I was a bit suspicious. But then after reading through , I was like wow.... :)

But before starting to download, I just scanned around the site and came to know that its a fake site... Dumb...
[Thinkpad Tablet Android Development] Grobie13:
Here is a new link to my mega K1 folder:

https://mega.nz/#F!JZdRQJTY

Please try out and report back.. :)

[Thinkpad Tablet Android Development] mujumj:
Thanks Grobie...

I'll definitely give it a try once I reach home.
[Thinkpad Tablet Android Development] mujumj:
Holly Cow!!!!!!! That was one helluva share....

I was trying to flash another file which I got (cm-10.1.3)...but tht after showing installing ended up in the Android with Exclamation sign...

And my K1 doesnt boot to recovery without an update.zip on downloads (Maybe coz of the stock ROM)...

Then I searched for an NVFlashable image and got one from your collection...

Now it is back on 4.1.2.

Thanks a lot...

But still hunting for an upgraded one...
[Thinkpad Tablet Android Development] user20211:
Can you please tell us if your K1 is WiFi only?

Edit: Finally Flashed K1_CM10_JB_Starter_v2.zip with gapps gapps-jb-20120726-signed.zip and it worked. Thanks Groobie13. Just a note: I still have the same problems, Youtube crashing at startup. I guess it is a gpu related problem... and no new rom will ever correct this... am I wrong?

Edit 2: installed an older version of YouTube and it works. By far the smoothest custom ROM I have tried on my K1. Thanks again groobie13.
[Thinkpad Tablet Android Development] mujumj:
Sorry for the late reply.

Yes, Mine was a K1 with Wifi only.

But it doesnt matter, because I was able to flash a 3G+Wifi version and it worked all well. Just that it shows a no signal icon on your notification panel.

Glad that you were able to flash it, nevertheless.
[Thinkpad Tablet Android Development] eldani.alonso:
Thanks Grobie13 for sharing this! I'll give it a try on my stock K1
[Thinkpad Tablet Android Development] user20211:
After a few weeks of searching and testing I finally found the files necessary with working links to install Android 4.2.2 on the Lenovo K1.

1. You must have CM10 installed. If you don't have it flash the file K1_CM10_JB_Starter_v2.zip from: https://mega.nz/#F!JZdRQJTY Decrypt key:!IuahBS-sxuR2P23rtxb9Sg

(Credit goes to groobie13 for uploading his personal files)

2. Get the following 4.2.2 Rom, again from groobie13: https://mega.nz/#!oBVCwABK!ELpuk2CGj7nPwIlNkCHX3EfyAWZ_q0YA_PrF78Jstr8

and install via sdcard from the recovery menu

3. Get the following gapps: https://drive.google.com/uc?id=0BwnAzQmV_2BIRFFXSEJ1MmVhdXc&export=download

and install again via the recovery menu.

I don't know if it is recommended to wipe the cache partitions from the recovery menu, but you could always do it later if you have problems.

Now you have a working android 4.2.2 on your K1.

Edit: Some issues are present. Like the Sleep of death: If you let your too much in sleep mode, you can't wake it up anymore. You have to press and hold the power button for 5-10 seconds to shut down your device and then power it up again.

Edit 2: if you have problems with gmail and other Google apps, you have to uninstall all updates from Google play services: settings -> apps -> Google play services -> uninstall ull updates, reboot. Upon launching gmail again, it will ask you to update Google play services, update it and gmail will work.
[Thinkpad Tablet Android Development] eldani.alonso:
Thanks [MENTION=8173342]user20211[/MENTION] !

I already got 1 and 3 thanks to [MENTION=1413395]Grobie13[/MENTION] and you.

But for file #2 I can't open it because I'm afraid URL got truncated (there's an ellipsis in it). Can you help by pointing out filename? (I'm already downloading the entire K1 folder from [MENTION=1413395]Grobie13[/MENTION] 's personal file store.

Thanks again
[Thinkpad Tablet Android Development] user20211:
Thanks, I fixed the link, I had it copy paste from another post and indeed it was truncated. Should work now.
[Thinkpad Tablet Android Development] eldani.alonso:
Thanks! It's working now.

Just one question: is this for WiFi or 3G version?
[Thinkpad Tablet Android Development] user20211:
It's the Wifi version.

Edit: it is the 3g/WiFi version but I installed it on my WiFi only version and it works so far.
[Thinkpad Tablet Android Development] user20211:
All we need for android 4.3 on our devices now is the last nightly update dated 2013-09-26 and probably named cm-10.1.3-RELEASE-k1-wifi.zip or cm-10.1.3-RELEASE-k1-3g.zip or even cm-10.1-20130926-NIGHTLY-k1.zip

I started searching for these but no luck so far.
[Thinkpad Tablet Android Development] eldani.alonso:
Thanks [MENTION=8173342]user20211[/MENTION]

Being that the case, and as I'm (just like you're) a WiFi-only owner, we can ask the father of the creature in case keeps some copy of the original files :)

So... [MENTION=4057521]kaschemme[/MENTION] in case you're still around here: do you keep copy of files from this post that you can re-share? Thanks in either case :)
[Thinkpad Tablet Android Development] hansan2017:
I was wondering if someone is still using their Ideapad K1 with this image. I recently tried it to give my old Ideapad K1 a new life. However I have / had the problem that the various Google related apps and services are pulling in libraries that use NEON instructions. Unfortunately is the Tegra 2 T20 not able to perform this kind of instructions. In the end are a lot off apps (like youtube) not working and is the log file filled with SIGILL errors. I do use the following file as start:

gapps-jb-20130427-nonneon-tonyp-keyboard.zip

Probably it is possible to prevent this by cherry picking the different apps; to check their version and walk manually through the update process. I didn't manage....

I went back to Android 3.2.1 which has a working youtube also after update. But it is not a very satisfying solution.

I don't see much messages about this problem with NEON instructions so I would like to know what I am doing wrong.....

Have others also problems with SIGILL error on various google services/processes?

Greetings,

Han
[Thinkpad Tablet Android Development] mujumj:
I dont have any problems with my gApps.

But I'm not using the package which you mentioned here (NEON). Once I'm back home, I'll check and let you know the same.
[Thinkpad Tablet Android Development] hansan2017:
Thanks for letting me know. I hope you can find out which package you have used.

I can only think of two "mistakes" I could have made:

1. I have started with the nvflash of the following CM10.1 image

CM10.1_Wifi_Kaschemme_v1

and then upgraded to the latest version

cm-10.1.3-RELEASE-k1-wifi.zip

with the recovery image. Maybe I should have used a different base. However with this I didn't see any errors in my log.

2. I had my wifi switched on when I installed the gapps

gapps-jb-20130427-nonneon-tonyp-keyboard.zip

, which made it possible to have all kind of unwanted updates running in the background.

I am looking forward to hear something from you. I am clearly one of the very few that has a problem with this NEON instruction issue.
[Thinkpad Tablet Android Development] hansan2017:
Just to answer my one message.

I have tried the following order without the wifi switched on:

nvflash: K1_CM10_JB_Starter_v2

recovery image: cm-10.1.3-RELEASE-k1-wifi.zip

recovery image: gapps-jb-20130427-nonneon-tonyp-keyboard.zip

And after that I have switched on the wifi.

Then I first didn't had any SIGILL errors in my logs, but when I installed youtube the errors started.

For completeness: the youtube app doesn't work.

My frustration is mainly that I am clearly the only one having this problem.

I also don't understand how "google play " should know from the data in the build.prop file that this tablet is armeabi-v7a but doesn't support neon. Only brand and model is giving a clue. I will try to change that to see if that gives different results.
[Thinkpad Tablet Android Development] mujumj:
Hey... Sincere apologies for the lack of response.

So, I'm on the 10.1.3-RELEASE-k1-wifi ROM.

And the gapps I have is gapps-jb-20130812-signed-4.2.2.zip
[Thinkpad Tablet Android Development] user20211:
I'm sorry, but where did you guys get the 10.1.3-RELEASE-k1-wifi rom? Could you please provide a link?
[Thinkpad Tablet Android Development] hansan2017:
Thanks for your response. Don't worry; I am only able to "work" on this very occasionally. I will try this combination as well.

Your gapps I don't have yet; I will have to search for that one. Or do you have a link?

Just for my understanding; you do have a working youtube app, google maps, chrome browser etc?

And which version numbers of those applications are working on your tablet? (Can be found under settings/apps...)

---------- Post added at 01:34 PM ---------- Previous post was at 01:30 PM ----------

There should be somewhere in this thread a link to this file. I do have it still at my computer; I will try to upload it to google drive or another host this weekend and leave you a (temporary) link to the file.

You can find the image here cm-10.1.3-RELEASE-k1-wifi.zip

Just let me know if it works for you.
[Thinkpad Tablet Android Development] user20211:
Thank you, just downloaded it, I'll try it as soon as I can.

Edit: just installed and it works great so far. Thank you again
[Thinkpad Tablet Android Development] hansan2017:
Good to hear that it is working. I will leave the file for a couple of months on my gdrive. Maybe others can use it as well.

Do you also have Youtube and/or Maps and/or Chrome working on your tablet?

Can you share which version and how you have installed them with me?
[Thinkpad Tablet Android Development] user20211:
Sorry for the late reply. Having tried this 4.3 rom for the last couple of weeks, I have encountered several issues like random reboots, google services stopping, network problems and so on. Also the UI gets really sluggish. I had to disable all animations to make the tablet usable, but it is still slow and unresponsive. I also tried overclocking to 1.4ghz but it did not help with the slow UI. App and games compatibility on the store is great, but half of the compatible ones does not run properly. I have not tried any youtube or chrome guessing that they won't work, so unfortunately I can't help you with that. I think that I'll just flash the 3.2.1 or the 4.0.3 and be done with it.
[Thinkpad Tablet Android Development] hansan2017:
The google service stopping and the sluggish UI response (of specific applications) is what I recognize from the moment I get apps that need NEON instructions on my tablet. Did you had a chance to look in the logs, with logcat for instance, to see if you have SIGILL errors in your log?

I did not experience random reboots and network problems.

Android 3.2.1 will not have this NEON instruction support issue. But was me too old and unsupported.

For Android 4.0.3 not so certain if you will get problems or not, please let me know good also be a good option for me.

I am now more or less successful on 4.3; that means I have a working browser, play store, maps and youtube. The user interface reasonable responsive. (I don't know if I have an underlying problem or if it is just the 6 year old technology.) That I got to that by disabling all the unattended updates and install manually some specific packets. When you are interested I can try to make detailed write up of what I did and share that with you.

How did you overclock the tablet?
[Thinkpad Tablet Android Development] user20211:
For me the UI was so unresponsive that it it took 5 to 10 seconds to switch between apps. I tried the 3.2.1, it was fast and responsive but as you said compatibility was an issue. I could not even get the amazon app store to run.

There is a Performance tab in Settings and the overclock option is there. I just tried it to see if it would solve the sluggishness and would not advise overclocking for normal use, since I've read people getting dead tablets that only heating the main board in an oven could bring back to life.

I tried a couple more ROMs and right now I am on khanning's jelly bean AOSP (4.1.1) with gapps already installed. The UI is fast enough that I can switch almost instantly between apps even with 4 or more apps. Chrome and YouTube from the store does not work, so I'll have to find older versions. I had no reboots or network problems. The default browser is responsive enough and I am typing this reply from my K1.

For anyone looking for khanning's JB AOSP, the ROM was on grobie13's mega folder.

edit: I have been using the khanning's JB ASOP for several weeks now and I must say it is probably the best custom ROM I have ever used on my 6 year old K1. It is rock solid stability wise, also fast and responsive. I get about 7 hours of battery life on normal use. If anyone is still searching for a good ROM for the K1, then khanning's JB ASOP is a good candidate.

[Thinkpad Tablet Android Development] ram1986:
Hi Kaschemme, great work.

I love this ROM. But I did notice something odd in the latest build.

Some system pop up messages now look a little stretched out.

Until the previous build, these used to be more compact.

(Example, the warning message you get when going to Performance options for instance).

Also, the CPU doesn't seem to scale at all. It just stays in 1G or 1.2 GHz and doesn't move to lower states. (in all governors).
[Thinkpad Tablet Android Development] ronimus:
Things I have found

Again, incredible job on the rom. I just wanted to post what I have found.

1. PC does not recognize the k1 as a storage device

2. The home button does not work. Only if I hold it while the tablet boots through the lights blight

3. External devices like mouse and keyboard work great (wireless)

Note: I flashed CWM over krook1's rom

Thanks again...
