My tablet froze up on my son again. I tried flashing the CM10 several times and it would fail, so I flashed the honeycomb.zip (which worked). After several attempts to flash CM10, it's now failing to flash any ROM using nvflash. The error I get is the following:

Formatting partition 2 BCT please wait.. FAILED!
command failure: create failed (bad data)
bootloader status: specified partition is invalid or does not exist (code: 7) message: nverror:0x42008 (0x6042008) flags: 0

Anybody have any idea how I can recover from this, or is my K1 a write-off at this point?

Thanks!

---------- Post added at 02:56 PM ---------- Previous post was at 02:09 PM ----------

OK, I was able to finally flash the honeycomb.zip (after about 10 attempts), but all efforts to flash CM10 send with the following error:

- 142382496/142382496 bytes sent
userdata.img sent successfully
failed executing command 26 NvError 0x120002

[Thinkpad Tablet Android Development] ti-pich:
Try to flash via the recovery instead of nvflash. Grab the zip you want, put it on the internal memory then go into terminal emulator or via adb and type k1recovery, it get you into cwm, then from there flash the zip you just downloaded. Be sure the zip you downlad are for recovery not for nvflash.
[Thinkpad Tablet Android Development] gm2racer:
I tried flashing through cwm, but it won't go any further than the initial Lenovo image upon reboot. I'm also not able to nvflash honeycomb (I've tried at least a dozen times). Guess it's time to upgrade...
[Thinkpad Tablet Android Development] ti-pich:
Strange, I've never had that much trouble flashing on ky k1. It failed randomly sometime but nothing more. Just to know, wich rom have you tried flashing from cwm.

EDIT: Also, is apx getting you the same error as before or another one.

EDIT 2: I managed to find a link wich is still up for the official ics from lenovo. You can try it if you want, there is the instruction attached in the link too at the bottom of the page. This doesn't come with google play or root or cwm.

Official ics
[Thinkpad Tablet Android Development] ronimus:
Kaschemme thanks a lot for the hard work and making our tablet current. I do have 2 questions before I make the upgrade.

1. I have the USB doggle, I understand that thumbdrives do not work at this moment, does that include USB mice and keyboards?

2. I am running Krook's latest version right now, it is safe to just the the recovery update?

Thanks, you guys are a great group!

nvflash_CM10.1_Wifi_Kaschemme_v1.zip is corrupt

me too:(
[Thinkpad Tablet Android Development] K1Andy:
It unzips OK for me using 7-Zip version 9.20 -- however, I have not tried actually installing it. Did you also check the MD5 checksum (3cef5e0a39a62e3866cdaa08309f94ca) to make sure that it downloaded without error? By the way, to be clear, we're specifically talking about the WiFi version of the nvflash file, so I make no claims about the 3G version.
[Thinkpad Tablet Android Development] vitoski:
K1Andy Thx for reply. Sure we talk about nvflash WiFi version. I did check the MD5 checksum and it do matches the one shown on website.

When I use 7-zip 9.20 and verify the archive it gives me around 44 files with unsupported compression format:(

On what system do you have 7-zip (XP, Vista, 7,8,Linux? and is it x32 or x64)?

[Thinkpad Tablet Android Development] kaschemme:
I just fixed the links for goo.im and added some mirrors. The nvflash files were compressed under linux as normal zip files.

Maybe the files are corrupted during the download from goo.im. The service is not very good.

The USB Storage is already fixed. I just need compile the nightly version.

This next nightly will include new media codec's from lenovo and media settings. Youtube HD videos (720p) should look much better.

I'll try to write a short script where you can upgrade just the recovery to the new version.
[Thinkpad Tablet Android Development] vitoski:
kaschemme huge THX for making CM10.1 for our tablets. I just have one question, would you please verify the ZIP with nvflash once again? I am just asking cause a few users have reported that the file is corrupted. I assume it downloaded properly for every one (at least comparing MD5) but somehow most unpacking tools cannot handle the file properly :(

I tried: 7-zip (couple versions), WinRar, WinZip and Windows embedded - no joy.

[Thinkpad Tablet Android Development] kaschemme:
I just deleted the links from goo.im. I'll upload the new files in a few minutes.

These files work with my Windows computer.

You can also use the files from the mirror, they are identical.
[Thinkpad Tablet Android Development] K1Andy:
kachemme, I do think there is something wrong with the nvflash files (at least the WiFi, anyway). I did specifically check the MD5 checksum after the download, and it is correct. However, I checked the unzip process again, and although 7-Zip looks like it unzips the files, I see now that many of them end up with a file size of 0. Only a few appear to actually be the correct size. If I try to unzip the embedded files individually, I do get an error message indicating an unsupported compression method. So maybe after you upload your next build, we can try again.
[Thinkpad Tablet Android Development] jerryatherton:
DARN GOOD

I wanted to warn everybody to make sure you use the GAPPS provided in the OP. I grabbed the incorrect GAPPS during the install in recovery and it pretty much locked up tablet. It took me a while to work through it but I finally got in running, I used the CWM flash version to download.

All my data and apps were gone as was my titanium backup. If you follw his instructions you will not have this problem. Anyway I have all my apps that I use frequently and almost all work flawlessly.

I ran a Quadrant Score and got 2800+. To put this in context, with the previous CM10 ROMS the scores ran from 1900-2400, the 2400 was attained with Kaschemme's last CM10 nightly. Galaxy 10.1 is about 2500 and a ASUS TF201 (quad core) is 4700.

I am in a hotel with a fair WIFI signal and have not experienced any dropouts.

The comment about the headset detection puzzles me, it worked fine for me on Netflix.

When I hooked the tablet up to a TV via HDMI it worked for about 3 minutes then the video froze on the TV (continued on the tablet) and the audio continued to play on the TV and tablet. Minor problem but the only bug I found.

Excellent, I think Kaschemme has added another year of life to my K1's (as long as they hold out mechanically, I have worn out my home button).

I also like the new tablet layout and notifications, clocks etc. I am not sure it is better but it does make it feel like a new tablet, LOL!
[Thinkpad Tablet Android Development] vitoski:
kaschemme may I ask when do you plan to release a newer nightly? The reason I am asking is simple - I do not know whether it's better to wait for next nightly (of released today) and go with totally fresh install or download once again the old one. Currently my tablet "died" and I need to flash it from nvflash.

Thanks!

[Thinkpad Tablet Android Development] kaschemme:
The next 3G nightly comes today or tomorrow. IF goo.im works :D

Just a short info about the correct GAPPS !!! It tooks a while to find the issue with the keyboard crash and GTalk crashes what I had before.

Read this Link and you'll understand it.

And Android 4.3 can come :fingers-crossed:
[Thinkpad Tablet Android Development] jerryatherton:
When mine died I went back and did a NV Flash of the latest CM10 ROM and worked forward from there. It took me a few hours.
[Thinkpad Tablet Android Development] vitoski:
Do you plan to release both 3G and WiFi nightlies or just 3G?

Wysyłane z mojego GT-I9100 za pomocą Tapatalk 2
[Thinkpad Tablet Android Development] kaschemme:
You got just 2800 ???

My score is @ 3277 with 1,4GHz :p

edit: just 3G nightly at this time. sorry ... It takes very long to change everything between 3G and wifi. wifi will come with a delay of 1 or 2 days.
[Thinkpad Tablet Android Development] K1Andy:
Kaschemme, I just wanted to let you know that I downloaded the new nvflash package, and it seems to be working fine with zip now. All is good! :good:

[Thinkpad Tablet Android Development] Mordred69:
I think it's fresh and new but, for me, I like the tablet look better to differentiate it from my other 3 devices :) But hey! I am not complaining, just an opinion. I also think this is a GREAT JOB and I concur with this ROM giving some more life to my tablet - I was about to just go and get a Tab 2...

Cheers! :highfive:
[Thinkpad Tablet Android Development] kaschemme:
I just released the 3G nightly on goo.im and dev-host.

On the first page is an update script for the CWM Recovery.

But this is only for experts.
[Thinkpad Tablet Android Development] :
I am wishing that somebody can create an APX flashtool, like the one used on Acer A500(I tried that tool but it can't detect my device even though it's on APX mode already and the Acer driver is installed. Hope someone who's savvy enough to modify that tool for K1)
[Thinkpad Tablet Android Development] gm2racer:
Yes it's the same error through APX:

Formatting partition 2 BCT please wait.. FAILED!
command failure: create failed (bad data)
bootloader status: specified partition is invalid or does not exist (code: 7) message: nverror:0x42008 (0x6042008) flags: 0

Also trying to flash the office ICS gives exactly the same error...
[Thinkpad Tablet Android Development] ti-pich:
Well... Is it possible for you to try it on a different computer. It may be your apx driver wich are too old or something like this. It seems like your bootloader isn't flashing correctly sometime so when it try to format there is nothing or the partition doens't exist and it make it crash.

NVFLASH commands

Hi [MENTION=4925834]Ameisentaetowierer[/MENTION]! I got questions about using nvflash commands, How do I operate the nvflash correctly on CMD? Should the device be in APX mode when running nvflash commands? I was also trying to get the partitionable text but I always fail getting the result for partitiontable.txt I always get this result

Nvflash v 1.8.90246 started

rcm version 0x4

Command send failed

Though I've read in TPT thread, where I also ask you, that if you get 0x4 meaning your bootloader is locked. Do you know how unlock the bootloader if there is such thing?

The commands are very jargon to me what should I input after K1 in this script specially the one in bold letters I am so lost I also am trying to understand the list of commands for nvflash but everytime I see scripts in these symbols "< >" I can't follow it anymore. Is there a guide to understand the nvflash commands? perhaps you could give me a link. Thanks in advance! :)

Hey guys,

Where can I get a dialer app for my K1 ? I have a 3G sim where I need to dial some numbers like (*800*25#) to activate 3G pack on that sim card.

Currently, I have to physically remove the sim, put it in a phone, activate the pack using the dialer, and then insert it back into K1 for use. This is quite hectic and time consuming :(

Please let me know :)

Thanx a lot in advance :)
[Thinkpad Tablet Android Development] :
Hi [MENTION=4263675]ram1986[/MENTION]! Is your K1 alive and running again? is that SBK the working SBK for all K1? I am still on brick state, actually the 7th brick state. I was able to flash the stock HC before this last brick but it wasn't also easy. Just like what you have mentioned on this post

The NVFlash to go back to Stock or Kaschemme's ROM also did not work. Getting this:

Formatting partition 2 BCT please wait.. FAILED!

command failure: create failed (bad data)

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

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

I also getting the same error even before my last brick and I also have a feeling that the emmc has been corrupted. Still searching over the internet to find ways how I could unbrick the tablet a bit easier way. I've been reading this thread on Rootzwiki (http://rootzwiki.com/topic/7593-bootloader/) by djmwj about bootloader and timmyDean's thread about Permanent root for K1. Upon reading and trying to decipher, it gives me a little hope. I am not a computer genius I only know how to surf the internet, check facebook, youtube and search. One of my big problem now is understanding commands for NVFLASH, anybody has an idea how to do the correct command for Windows 7?. I can't communicate my K1 and PC very well. If I use this command

nvflash -r <whatever correct command follows>

I end up with indefinite:

Nvflash started

[resume mode]

And if I not use the -r after nvflash for other commands, let say getting partition table or ending the command line with --go, I get an error of 0x4

Does manually doing this on Windows 7 CMD work? Hope to hear your insights too. Thanks

I don't see why, I'd be willing to donate $150 for a rom build for the yoga. There's already a Dev on github who posted hardware info about it and a method of getting CWM.
[Thinkpad Tablet Android Development] Kazekage Gaara:
Hi guys,

Am facing a weird issue. When I put my K1 to sleep by single pressing the power button and leave it that way, it would sometimes just wouldn't wake up. I know everything is still running because the backside is still warm, but the screen just wouldn't light up. My only option here is to hard reset it and turn it on again.

It's like am playing a game, and I pause it for a moment to run an errand, and when I come back after a few minutes, the K1 just wouldn't wake up :(

Is anyone else facing this issue with the latest version of this rom ? Please let me know how I can prevent that from happening.

I have the 3G version of Lenovo K1 :)

Thanx a lot in advance for any info :)
[Thinkpad Tablet Android Development] :
Hope you didn't OC your K1. That might be the culprit.
[Thinkpad Tablet Android Development] Kazekage Gaara:
Yup, I did :P In fact, that's the first thing I did after booting it up for the first time. OC'd it to the MAX setting of 1.4 Ghz. So far, it seems to be running stable without any crashes, etc. The only thing bothering is sometimes it won't wake up after going to sleep :)

anyone know how to solved this?

please, need any advise..

You must start your tablet as usual. Then reboot into recovery. Unfortunately you can't start into recovery by holding buttons.

Edit: sorry I missed something, with bootloops you can't start as usual...

If you enabled adb then it should work even in a bootloop. Plug your tablet in your computer then type adb reboot recovery. This should do the trick.

Hi guys,

I have the 3G version of Lenovo K1, and I am unable to turn "wifi hotspot" on. Whenever I click "Portable Wi-Fi Hotspot", the option GREYS OUT and shows "Turning hotspot on..." and it stays like that FOREVER, without actually turning the hotspot on.

I even click "Set up Wi-Fi Hotspot" and tried out all the 3 security settings, "Open, WPA2, and WPA" but it's the same for all of them. It just won't turn on :(

Is there any particular reason behind this ?

Thanx a lot in advance for the help :)

Edit: By the way, USB tethering works just fine :)

Edit II: Is there a way to make Bluetooth tethering work ? I have a Galaxy S3 (on stock 4.3) and I am trying to share my Lenovo K1's 3G internet to my Galaxy S3, either via Wifi Hotspot or Bluetooth.

Guys, please help me out with this :(
[Thinkpad Tablet Android Development] Kazekage Gaara:
Anyone ?
[Thinkpad Tablet Android Development] ti-pich:
The wifi driver are too old for android 4.2, that's the reason why we have SOD and I think this why the thetering isn't working too. There is nothing we can do for it.
[Thinkpad Tablet Android Development] kaschemme:
That's right. We're using the bcm4329 wifi driver, which aren't compatible for tethering. You see that option but can't use it.

With an other (new) driver is it possible to create a hotspot.

This new driver (bcmdhd) has only worked for 50% on my tablet and did a lot of trouble.

bluetooth

The best i can figure i have installed this rom and the gapp rom and everything appears to be working fine. It also did a nightly update. I searched the thread but did not get conclusive answer to cure for non working bluetooth.

So my question is, does bluetooth work, is there an update or setting i am missing and if not working is solution right around the corner. I need it to work because of the way we will use the tablet. Thanks
[Thinkpad Tablet Android Development] jerryatherton:
Bluetooth was a problem for most devices on JB. It has never worked on the JB K1.
[Thinkpad Tablet Android Development] firepro1110:
Great thanks for the feedback.
[Thinkpad Tablet Android Development] K1Andy:
Actually, didn't it work OK on the CM10 (Android 4.1) JB versions of the K1 ROM? I used to be able to do bluetooth audio before going to 10.1. I think that's when they dropped the previous "Bluez" stack and moved to something new.
[Thinkpad Tablet Android Development] jerryatherton:
Maybe, that was a long time ago. I have a few HP touchpad running KitKat and they have working Bluetooth.
[Thinkpad Tablet Android Development] mjb32803:
I'm running cm 10.1, android 4.1.2 and blue tooth works flawlessly. Have personally used it with audio, mouse, and keyboard.
[Thinkpad Tablet Android Development] K1Andy:
Hmmmm, mine broke when we went to 10.1, and even in his final release (10.1.3) notes, kaschemme had indicated that Bluetooth was still not working:

I've completed the release version for our K1.

The files are already up on the file server but I've to test the version.

Tomorrow you could check the OTA updater and download the 3g or wifi version.

Here is the changelog:

CyanogenMod 10.1.3 Release

- CMAccount (https://account.cyanogenmod.org)

- OC Kernel

+ max. 1.4 Ghz

+ add UHID / HID Driver

+ optimized battery usage

+ small BCM4329 fix

- Updated system apps

+ CatLog

+ OTA Updater

+ RootBrowser

- Removed GooManager

- add smaller font footprint

- some Bluetooth fixes (But they don't work)

- CWM 6.0.3.5 (CWM will install automatic)

- Data Usage reactivated

- removed Lenovo bootanimaton (creates black screen during the booting)

->My AnTuTu Score 10348

Update:

Oh, wait, you said CM 10.1, but then Android 4.1.2. I believe Android 4.1 is CM10, and Android 4.2 is CM10.1. So if you are really on 4.1.2 (CM10), then yes, Bluetooth did work on that version. If you're on 4.2.2 (CM10.1), then I don't think it does - at least for me, or jerryatherton, or kaschemme.
