Awesome work buddy !!. Downloading it. But will flash over the weekend.

Thanks for continuing work on this device.
[Thinkpad Tablet Android Development] ti-pich:
Nice work! I've flashed it yesterday when you posted it on goo.im and it's running nice so far. Got sod but I put wifi to always on, anyways it doesn't seem to drain too much battery. Also maybe you should update the recovery as this one cause 0 folder nesting when flashing(I got emulated/0/0/0...) and this is repaired with newer recovery, I don't remind wich number. Everything else seem to be working perfectly, some little strange thing but I think it's due to CM nighlties and could be working correctly later. I'll thank you so much for keeping our device alive. Keep it going.

Edit: The recovery issue is fixed since cwm 6.0.2.3 and we got 6.0.1.1 so that's why it's nesting but that isn't dangerous or anything, it can be deleted and the data are simply at the bottom of the 0 folders tree.
[Thinkpad Tablet Android Development] Mordred69:
Thank you, kaschemme! Will download and flash when I get home as my tablet does not have too much data. THANK YOU!!!

Where can I get this recovery file to flash on my tablet? Thanks! :good:
[Thinkpad Tablet Android Development] ti-pich:
It isn't made for our device yet so we can't flash it. It need to be updated and compiled from the rom source then it can be flashed so for now we have to live with this version.
[Thinkpad Tablet Android Development] jerryatherton:
Way to go!!

On goo.im for devs/kaschemme/nvflash/nvflash_CM10.1_Wifi_Kaschemme_v1.zip

"The file you requested was not found. Lets see if we can find that for you..."
[Thinkpad Tablet Android Development] ti-pich:
There isn't nvflash folder in kaschemme. For me kaschemme/CM10/nvflash/nvflash_CM10.1_Wifi_Kaschemme_v1.zip download without any issue.
[Thinkpad Tablet Android Development] K1Andy:
Hey, kaschemme, thanks so much for the update! I am looking forward to giving it a try, although I do use the USB Storage function a lot (it's the easiest way to copy movies onto my K1), so I might wait until after my vacation to do the update. I'd also like to see how the GPS functions are working, since I use my K1 a lot when I go geocaching. But it's wonderful to see that the K1 is still moving forward! :good:
[Thinkpad Tablet Android Development] ti-pich:
USB connection to a computer do work for me on ubuntu 13.04 better than it ever worked. I think by USB storage he is meaning USB OTG, like plugging a usb key directly in the K1 with the almost inexistant lenovo adapter.
[Thinkpad Tablet Android Development] K1Andy:
Right, USB host support (attaching a USB flash drive to the K1) is exactly what I mean, and what I use. I was fortunate enough to get one of those non-existent adapters.
[Thinkpad Tablet Android Development] Mordred69:
The problem is the NVFlash links.

The file is not at http://goo.im/devs/kaschemme/nvflash/nvflash_CM10.1_Wifi_Kaschemme_v1.zip

The file is at http://goo.im/devs/kaschemme/cm10/nvflash/nvflash_CM10.1_Wifi_Kaschemme_v1.zip

Means it is inside the CM10 directory :D (linkage truncates whole sentence)

Thanks, ti-pich! Thanks Kaschemme!
[Thinkpad Tablet Android Development] ti-pich:
You are really lucky then, this is probably the only thing missing on this tablet, and that's why I'm waiting for google to release their nexus 7 full hd with a regular micro usb. Anyway, sorry I misunderstood what you said.
[Thinkpad Tablet Android Development] Mordred69:
Kaschemme,

nvflash_CM10.1_Wifi_Kaschemme_v1.zip is corrupt. Downloaded 4 times. :(
[Thinkpad Tablet Android Development] jerryatherton:
Great job Kaschemme!

So far all my apps that I have reloaded are working. Thanks for your hard work.
[Thinkpad Tablet Android Development] K1Andy:
I downloaded it, and it does appear to have the correct MD5 hash signature, but if I try to open or extract it using Windows Explorer, I also get a message that it is invalid or corrupted. However, if I use 7-Zip, it seems to open and extract with no problem. Perhaps it was built using some type of zip compression that isn't supported by the built-in Windows compression tools?
[Thinkpad Tablet Android Development] Mordred69:
Thank you. I was using winrar which is what I always use. In any case, I flashed this rom's cwm version over krook1's nvflash starter v2 and it worked, but gives me the same errors as krook1's version 6.1, which are random apps closing with no explanation whatsoever... Not even a "sorry, xyz app has forced closed" message. Keep in mind this is a fresh install.

This flash also started complaining that email had closed right from the start, too. I hope this helps you guys...
[Thinkpad Tablet Android Development] myson_aeroplanino:
hei Kaschemme.

thanks u so much!!!

this rom run so well.. the performance got better from the previous one.

i dont found any bug yet, but i read ur first post, that there is a bug on Headset detection...

let me try when i got home

anyway, great job!

Edited :

i just try to plug my headset on my K1..

And it works well..

So up to now, i dont found a bug yet...

Cool!
[Thinkpad Tablet Android Development] Hetalk:
Take a nandroid backup and try doing a clean flash (factory reset then flash), in case you did a dirty flash.
[Thinkpad Tablet Android Development] vitoski:
Would you please let me know which version of 7-zip you used to extract the files from nvflash archive?

I tried 9.20 and 9.30alpha and both give me 'unsupported compression method' :(

[Thinkpad Tablet Android Development] K1Andy:
It sounds like your WiFi problem is probably not something that a new ROM will fix. My WiFi has worked fairly consistently (generally, at connect speeds of 56-72Mbps) with all of kaschemme's ROMs, as well as with krook's CM10, and with the original Lenovo Honeycomb, but it looks like you've had ongoing problems on several ROMs. Also, I don't believe there has been any discussion of any pending WiFi fixes. I assume you've tried your K1 with different routers, in different environments. You may just have a weak WiFi antenna, and based on early comments in the Lenovo forums, I don't think you're the only one. In fact, I remember reading a while back about someone making a physical modification that improved their WiFi signal, but in a quick search I haven't been able to find it again.
[Thinkpad Tablet Android Development] steve30x:
Yes I used it at my sisters house where they have a different router and at my brothers house with a different router and its the same. The only reason why I want an update of this rom is because with this rom my wifi refuses to work but with Krooks CM 10 rom my wifi does work. The Wifi in Krooks rom orks better than the stock rom did. I suppose I am one of the very few who got bad hardware.
[Thinkpad Tablet Android Development] kaschemme:
new oc nightly

I have a test nightly for you!

But you must be aware that it doesn't work flawlessly on every tablet.

The OC is up to 1,6 Ghz and some devices made problems with this high clocking.

Everyone can install and test the update (It's a 3G nighty).

If I hear too many issues or bugs than I reduce the OC down to 1,4Ghz.

Link 1 @ MEGA

Link 2 @ Dropboxhttps://db.tt/6g06HAUv

Note: My K1 had no problems at all but my german tester couldn't run his K1 at top speed. His K1 stopped during the booting and he must reduce the clocking.
[Thinkpad Tablet Android Development] jerryatherton:
It looks like I am downloading it, but I can't find where it is going

Hi Steve,

can you describe the "wifi problems" in detail?

[Thinkpad Tablet Android Development] traihan:
Hi kaschemme

Just played around for 10 min. 1.6 seems to hang (not at booting,but once I start running some app) but 1.5 works fine. If I see anything else I will inform here.

Thanks for the ROM again.
[Thinkpad Tablet Android Development] steve30x:
Facebook is extremely slow to load pictures , browsing the internet is slow , Google playstore constantly times out after a very short while and youtube constantly times out after a short while
[Thinkpad Tablet Android Development] jerryatherton:
My WiFi working great with that last 9/17 build. I tried YouTube and play store both were good. I over clocked to 1400, got a quadrant of 3600+. Antutu was 11270. Like your stuff. Thanks!
[Thinkpad Tablet Android Development] Ameisentaetowierer:
Strange.

I know that disabling "Wifi - always on" leads to SOD when not using krooks rom (kernel) and that at least one user faces crashes when leaving the range of his access point ...

Krook was using a different kernel module for wifi. With that one you could even let wifi go to deep sleep without SOD.

Maybe krook can share his kernel sources?

I've already asked him, but didn't get an answer.

Micky

This message has been checked by project PRISM.
[Thinkpad Tablet Android Development] kaschemme:
The same with me. I didn't get an answer from krook. He was using the bcmdhd wifi driver. This one never worked with my cm10.1 source code.

For that reason I used the "old" driver (bcm4329).

Some information for the next nightly! The next nighty (wifi & 3G) will be the last update, maybe. The source code will get a code freeze in a few days. Also, I'll not create a CM10.2 (Android 4.3) for our K1 !!

The android 4.3 version is not for our Tegra2 chipset and I saw just one Android 4.3 mod for a Tegra2 device.

BUT, what I heared is the next android 4.4 for older devices.

We should skip one version and try the next one ;)
[Thinkpad Tablet Android Development] K1Andy:
Yeah, I knew that krook had a driver that dealt with the SOD issue better, although I never really noticed any difference in the basic quality of the connection.

Steve30x, I didn't mean to say that the only explanation for your WiFi issues had to be hardware, but there were enough early complaints about the K1's WiFi that I wanted to point out that it could be a possibility. So if the basic issue is that your network response seems to be slow, what actual connection speed is your WiFi reporting? Have you used some tools like WiFi Analyzer or WiFi Manager to check signal strength and connection speed?

---------- Post added at 04:02 PM ---------- Previous post was at 03:57 PM ----------

You've already given us a much more useful life for our K1s than Lenovo ever did, so even if there are no more updates after this one, it's been great! :good:

.....even so, I'd probably still be interested if 4.4 happens to run on our Tegra2 tablets!
[Thinkpad Tablet Android Development] ti-pich:
Running great at 1.6ghz for me, even when playing gta vice city with maxed out setting. Overall performance seems to be really nice. Thanks again for this rom.
[Thinkpad Tablet Android Development] steve30x:
I have very strong WIFI. It works perfect with my laptop out in my garden twenty foot from my house, it works perfect with my Samsung Galaxy Ace Plus out in my garden , it works perfect with my brothers samsung galaxy mini and it works perfect with my brothers IPad. Its just my K1 has trouble with wifi. As I said before thye WIFI works better with Krooks CM 10 but I cant get wifi to work with kaschemme CM 10.1. Also I know about the SOD with the WIFI and I have the wifi set to be always on.
[Thinkpad Tablet Android Development] K1Andy:
I think you missed the point. The question is not how good your WiFi is with your other devices, the question is what kind of signal strength and connection speed you are actually seeing

on your K1

. Poor signal strength could be a sign of an antenna/receiver problem with your K1. On the other hand, if your connection speed is good but you are still seeing slow responses in your apps, there could be some other interference. For example, I assume you've also checked to see if there are any processes that might be consuming CPU time, causing a slowdown? Some processes, even if only communicating within the K1, can still cause bottlenecks in the IP stack.
[Thinkpad Tablet Android Development] steve30x:
WIFI Manager is reporting a 3/4 bar signal just eight foot away from the router with 2MB/s speed
[Thinkpad Tablet Android Development] vitoski:
Just two cents from my side. I also believe K1 has poor wifi reception. I have two devices, K1 and Note 10.1 and Note had way better reception.

I was comparing both devices with the same router, the same place, the same distance.

Wysyłane z mojego GT-I9100 za pomocą Tapatalk 2
[Thinkpad Tablet Android Development] K1Andy:
Yeah, that's definitely not normal, even with the older BCM4329 drivers in kaschemme's ROM. You should be getting a much better connection speed than that. For example, right now (with Kaschemme's ROM) I'm getting 72Mbps connection speed with 3/4 signal bars, and my router is upstairs at the other end of the house.

As to why your K1 seems to work better with krook's bcmdhd (Broadcom Dongle Host Device) drivers, it's not clear. They handle power management a little better, so I suppose that might have something to do with it. They were also open-source, and provided a better configuration API, but that shouldn't affect your connection speed. It could be that they're just a little better, enough to make a bad connection tolerable, but it would be interesting to know if you really see better signal and connection speeds with the bcmdhd drivers.
[Thinkpad Tablet Android Development] gm2racer:
kaschemme, can you create a wifi only version of this build?

Thanks!
[Thinkpad Tablet Android Development] K1Andy:
kaschemme, have you received any private messages from me - specifically, the latest one about overclocking? They are not showing up in my "Sent" folder, so I can't tell for sure if they're being sent. :confused:

Update:

For anyone else using kaschemme's latest (9/16) nightly with the OC enabled, you might want to keep your eye out for CPU frequency exceeding the governor setting. Of course, the only way you might see it is if you have some sort of system monitor running (I use one called "Cool Tool"). I usually run with the governor set at the normal max of 1000MHz, but I saw the CPU jump up to 1600MHz at one point, and it caused my K1 to reboot - and when it came back up, CPU was still jumping up to 1600MHz (and then it hung). After a forced power-off and reboot, it went back to normal.

I saw this happen a few times with krook's ROM, too, but because he only allowed a max of 1400MHz, my K1 seemed to handle it OK, and I could force the CPU back in line by setting the governor to something else (the actual governor value, as reported, did not appear to have changed), then back to 1000MHz.

So, if anyone else is seeing this, or is experiencing unexplained reboots or hangs with the latest ROM, perhaps it would be better if kaschemme set the max OC to 1400MHz (unless, of course, he has an idea why it might be exceeding the governor setting)?

[MENTION=4057521]kaschemme[/MENTION]

Thanks for this awesome ROM

My tab working like a rocket,

It's a rock solid, and fast...

Had lenovo launched K1 with this ROM, it would have been a grand success...
[Thinkpad Tablet Android Development] kaschemme:
I could create one but the new OC kernel makes only problems at the moment. To get better performance for all, I will put the speed down to 1.4 Ghz. That should be enough for all.

I got your mail :good:

What I see so far is, that we have very strong differences in quality. I could run my K1 @ 1.6Ghz and my Wifi had no interuptions. Others had bugs with the oc kernel and wifi signal.

Give some days to create a good runing build (3G and wifi). The new build will have the CMAccount feature!
[Thinkpad Tablet Android Development] K1Andy:
That sounds good - thank you! :highfive:
[Thinkpad Tablet Android Development] steve30x:
I got an Acer Iconiatab A500 to replace the K1 today. What I dont understand is the Acer runs faster even though this K1 has the exact same Tegra 2 CPU and same 1GB ram. The ACER is allrouind better. The wifi works flawlessly. It takes perfect pictures and it runs faster with all the same software , but I am using the stock rom rooted.
[Thinkpad Tablet Android Development] traihan:
Hi kaschemme

Thanks again for the ROM.

Would you please leave the OC at 1.6 or may be 1.5. Lot us can run at that speed. Those who can not run at 1.6/1.5 can lower their OCing.
[Thinkpad Tablet Android Development] K1Andy:
If you read my earlier post, the problem is that the CPU frequency is sometimes jumping to 1.6,

even with the governor set at 1.0

, and this occasionally happened on krook's ROMs, too. It doesn't happen very often, but when it does, it can crash/hang those of us with K1s that are not stable at that speed - even when we are not (intentionally) overclocking. I don't remember hearing of anyone that couldn't run at 1.4, so that's why I suggested lowering the max OC speed, so if someone gets one of these unexplained CPU bursts, it won't crash/hang their K1.
[Thinkpad Tablet Android Development] kaschemme:

[Thinkpad Tablet Android Development] -MaD-:
OC comes back to my "gaming rig" ;) :thumbup:

I'm a little sad to hear BT is still not working, but I got used to use a cable like in good old Walkman days, so: thanks for doing this work for us!

Thanks Kaschemme, you have done an amazing job with this tablet.

EDIT: is it on the CM site yet?
[Thinkpad Tablet Android Development] kaschemme:
Update is online

Thanks to all!

Wifi Version is online.

Start OTA Updater and check for new updates.

Edit: 3G is online too, check the ota updater

Edit 2: no wipe needed.
[Thinkpad Tablet Android Development] wmarcin:
You're the man!

Update without wiping anything?

No need to flash Gapps, correct?

Many thanks!

Edit. Coming from the latest WiFi nightly.
[Thinkpad Tablet Android Development] traihan:
I am on the 3g ver of the 9/16 nightly. OTA now wants to install the 3g very of the 9/26 release. How do I go back to WiFi version of the 9/26 release.

Thanks
[Thinkpad Tablet Android Development] ti-pich:
Edit your build.prop.

The line to change is this one:

otaupdater.otaid=cm10.1_k1_3g

You change it for this one:

otaupdater.otaid=cm10.1_k1_wifi

and then reboot and check for update. It will show the wifi version.
[Thinkpad Tablet Android Development] K1Andy:
Finally got a chance to download the update and install it. Running great! Thanks so much, kaschemme, for all your hard work! :good:
[Thinkpad Tablet Android Development] traihan:
Okay, thanks.

Just did it. It worked. How do I confirm that it actually changed?

OTA never worked for me. It sort of hangs at about 1/3 of the way at installation. I just do it manually from the reboot menu after Ota downloads it.

Edit

Antutu score. 9/26 WiFi @ 1.4MHz 9806

9/16@1.5MHz. 11155
[Thinkpad Tablet Android Development] ronimus:
Absolutely incredible!! This rom is the the best.. The only mystery is the "HOME" button. It works if held during boot process, but does not work at all in recovery (CWM).

Again, the best ROM to date. THANKS!!!
[Thinkpad Tablet Android Development] K1Andy:
The HOME button issue has been a really strange one. For some people it seems to work all the time (mine does), others not at all, and for some it works if held down during boot - which really makes you wonder. We're running the same code, especially in Recovery mode, and there can't be much complexity to the hardware (probably some GPIO port). Weird. :confused:
[Thinkpad Tablet Android Development] jerryatherton:
My HOME Button has not worked for over a year. I use Rom Manager by CWM. You can use that for flashing and you will not need a home button. It works great. When you install it, make sure you answer that you have an installed recovery. It will come back with a device and answer that they have not found your device. It will find your recovery and you will be all set. Good Luck.
[Thinkpad Tablet Android Development] ronimus:
I use the same app for flashing...but the home button is a mystery I want to solve. I was the one who experimented with the home button and found the boot trick. Just wish I could figure the rest of it out.
[Thinkpad Tablet Android Development] jerryatherton:
Mine is a mechanical failure. I bought a home button assembly a while back, but never got the nerve to disassemble the K1 to replace it.
[Thinkpad Tablet Android Development] ti-pich:
Maybe there is older model with a certain home button module and they changed for another module somewhere in production so the newer have another module, wich one of both wouldn't be supported by the current driver. Or, I don't know, maybe only user with the 3g have the home button issue, I have no idea. There need to be something in common with all the k1 with defective home button. Something missplaced with nvflash in some partition or bootloader. There is many possibilities.
[Thinkpad Tablet Android Development] ronimus:
Strange....What about CWM? If I remember correctly the HOME button worked fine in version 5 and also if you hold the HOME button during boot into CWM it has no effect. This is what I consider some of the fun is trying to debug this issue.

Thanks for your input! It's appreciated.

Hi kaschemme

Is there any hope of fixing the BT. I travel a lot and used the BT a lot with a BT headphone.

But thanks again for the otherwise awesome rom.
[Thinkpad Tablet Android Development] passy05:
Hi Kaschemme, I have been using the version available on Goo for few weeks without any problem. I installed the latest version few days ago and I got some random reboot during the night when the tablet was in sleep mode. Now it is stuck on CyanogenMod boot (I tried to restart several times). I would like to boot in recovery mode to do a full data wipe (I have not done it during the last upgrade). Any idea how to boot in recovery mode (usual Android way Volume button does not work on K1). I would like to avoid using nvflash in case there is something wrong with my tablet.
[Thinkpad Tablet Android Development] ti-pich:
You can boot into recovery with adb from the boot screen. Simply plug your device on your computer while on the bootscreen and type adb reboot recovery. This should reboot the tablet into recovery if it haven't stopped booting before adb was launched.
[Thinkpad Tablet Android Development] passy05:
Good idea but did not work. I don't think I had the USB Debugging option enabled.
[Thinkpad Tablet Android Development] myson_aeroplanino:
Hi, i want to ask something.

Can i use this tablet for making or receiving a call?

What app to do that things..

Thanks in advance
[Thinkpad Tablet Android Development] badboyblue:
Thanks for the update. Keep it up
[Thinkpad Tablet Android Development] wmarcin:
I think GrooveIP + Google Voice can do that for you. But recently Google Voice changed its app so that it can be used to make calls using mobile provider's voice minutes, so I'm not sure if it still works with Groove IP.
