upon my cm7 experience on A1, maybe some setting variance on my pad, the wifi signal always drops and become error after two to three times screen on and off, even above wifi never sleep option is activated.

it is normal as u re-partition your A1 as no internal SD as "emmc"

GPS time issue

Like a number of other Android devices, the A1 suffers from the GPS time leap year bug (see Android issue 23937). I had hoped that the issue would simply go away after February, 29th. Unfortunately it's still there. Is this fixed or fixable in the CM7 build?

To see the problem, use Chartcross GPS Test and look at the GPS time. It's one day off.
[Miscellaneous Android Development] Aero1550:
Installed update-cm-7.2.0-RC0-A1_07-KANG-signed.zip coming from stock 2643_ROW after factory reset/wipe.

After rebooting I am stuck in CM7 boot animation. Reflashed, rebooted, no change.

Zip seems complete and undamaged (MD5 3a0907ff66327590fe21ba227dcbb16b)

Any ideas before I go back to my stock 2643 backup?

[EDIT: another factory reset and reboot did it, now happily in CM7]

[Miscellaneous Android Development] multijoy:
I had the constant animation issue as well, but a factory reset did the trick.

Did have wifi glitch on me (wouldn't turn on, and then rebooted), but hasn't seemed to have reoccured.

I can't, however, seem to get the market app installer to fire (using file manager > system/app/pumpkin), but that might be a peb(soft)kac :p

[Miscellaneous Android Development] edl0022:
Thks, the CM7 is great. i found the RC0 still some bugs.

1, sometime the streaming video will hang the a1 and it needs reboot.

2, sometime the streaming video's sound and video is not in same speed. (apps PPTV)

3, the rotate lock button is not working.

i hope the following service can be in the rom

1, Google service.

2, WIFI can on/off cannot reboot the machine.

3, remove the phone function if it is not the 3g version

Are you using the 27th Feb nightly (the last one that ever got build before my build machine died? Or are you using the one that I posted a couple of days ago hosted on animes.wa.zettaimurri.de?

Is it a hard reboot or a soft reboot? (Hard reboot: you see the Lenovo logo again... Soft reboot - it jumps back to the Cyanogenmod logo)

If it's a hard reboot, could you get a copy of /proc/last_kmsg please? You can get this by plugging into a computer and running

adb pull /proc/last_kmsg

Could anyone else who's having these issues also please try and do the same? Many thanks!
[Miscellaneous Android Development] multijoy:
Just come across a real issue (rather than one of my own devising), albeit intermittent.

Running CM7, latest build from anime.wa.

wifi-sleep policy is still default (off with screen)

I change this policy to 'never'

Lock screen and make a cup of tea

Return, wifi has turned itself off.

Switch wifi on, tablet pauses and shows 'error', then 'off'. Switch wifi on and tablet hard resets.

I've not had a chance to see if I can reproduce it yet, but it's happened a couple of times - will see if I can get a chance to force it to do it.
[Miscellaneous Android Development] gmarkall:
We're still using the stock wifi driver as we haven't got the kernel source yet - unfortunately it's full of issues - I didn't realise it could cause a full-blown restart though. I'll amend the list of issues.

Hopefully the kernel source will be release soon and we can take a proper look at this.
[Miscellaneous Android Development] unplugged138:

no
[Miscellaneous Android Development] multijoy:
Right, I can reproduce the error -

Hard reset, unlock, go to settings->wireless & networks.

Turn on wifi. Let it connect.

Turn off wifi, wait a few seconds, turn it back on.

It then turns off without connecting (or scanning)

Turn it back on, it displays "turning on.." and then "error"

Push to turn it on, it resets.

I can only surmise that if you set wifi sleep to 'never', there is still a timer or something that powers wifi down anyway, after a sufficient length of time, which would explain why it crashes when it comes back to life.

NB the reboot only seems to occur when you try to restart the wifi- it's quite happy in it's powered down state. Obviously this gets no further as to why the wifi seems to give up the ghost!
[Miscellaneous Android Development] monsefito:
Im running CWM 7 and latest nightbuild. My Wifi works fine. When the scrren is off it's disabled and it turns on in screen wake up...
[Miscellaneous Android Development] mikelets456:
That's how mine works on build 17/18..off when screen on and comes on instantly when screen comes on.... BTW, I have not had a reboot or FC in almost two weeks. I am afraid to move up... I can view MP4 videos, Youtube, Tango facetime, take pictures, listen to music, books, etc, etc etc. I'll stay on this build for now. Thanks again for all the hard work you all put into this.

BTW, I love reading these posts and learning how the process goes, very interesting and insightful.

Actually, there is one "quirk"... maybe it's Tango. If I make a video call once in a while the camera (front) is not centered and upside down...however, the person I am chatting with says it's fine. Oh well, just some thing I wanted to mention.
[Miscellaneous Android Development] ehsangolpesar12:
hi, I am using the one from «animes.wa.zettaimurri.de», I believe that it was the last one, am I right?

I will send you the last_kmsg as soon as I get back to my PC, or is it possible to find it on tablet using I don't know , Terminal Emulator ?

[Miscellaneous Android Development] ppetermann:
I installed the latest version yesterday and after some initial problems with the Installation it seems to run quite well now — with being able to run tablet specific applications like the swiftkey x tablet keyboard its use gets so much better.

one thing though, and I'm having the 16 gb version of the tablet and the path to the internal sd seems to have changed. some of my apps did not find their data because of that.. (kindle, gallery...) its no big drama but a bit annoying.

Anyway thanks for all the work you guys are doing, it's really appreciated
[Miscellaneous Android Development] milaq:
this is becaue lenovo mounted the sdcards in a very hackish way (as they're doing it with the whole os).

on stock the internal sd gets mounted to /mnt/sdcard/ and the external to a folder in /mnt/sdcard/ (/mnt/sdcard/removable_sdcard).

on CM7 both cards are getting mounted to proper locations (/mnt/emmc and /mnt/sdcard).
[Miscellaneous Android Development] gmarkall:
Thoughts on the wifi reboot issue

Some (slightly vague) thoughts on the wifi reboot issue:

The first time the wifi is turned on, we see in kmsg:

<4>Dongle Host Driver, version 4.218.248.25
<4>Compiled in /home/user/cl1_disk/bw-fw-2.3.4/mydroid/hardware/broadcom/wlan/bcm4329_fxn_248/src/dhd/linux/../.. on Oct 7 2011 at 17:41:59
<4>+++check SDIO on mmc2
<6>mmc2: new SDIO card at address 0001

Then when wifi is turned off, the dhd module is unloaded. The next time we turn on wifi, we see:

<4>Dongle Host Driver, version 4.218.248.25
<4>Compiled in /home/user/cl1_disk/bw-fw-2.3.4/mydroid/hardware/broadcom/wlan/bcm4329_fxn_248/src/dhd/linux/../.. on Oct 7 2011 at 17:41:59
<4><<< dhd_module_init
<6>mmc2: card 0001 removed
<4>+++check SDIO on mmc2
<3>mmc2: error -110 whilst initialising SDIO card

It doesn't seem to see the BCM4329, which it looks like is an SDIO device connected to mmc2.

The third time, which always causes the reboot, we have:

<4>Dongle Host Driver, version 4.218.248.25
<4>Compiled in /home/user/cl1_disk/bw-fw-2.3.4/mydroid/hardware/broadcom/wlan/bcm4329_fxn_248/src/dhd/linux/../.. on Oct 7 2011 at 17:41:59
<4>+++check SDIO on mmc2
<4> err: -110
<4>---check SDIO
<4><<< dhd_module_init

The "check SDIO on mmc2" fails with the same error, -110, but it seems as if it's failing slightly earlier. However, it still goes on to call dhd_module_init, which I suspect is causing the reboot, by trying to access some invalid pointer for the device it can't see.

The greate A1 ROM that I had never experienced!

I am using the ROM "update-cm-7.2.0-RC0-A1_07-KANG-signed.zip" with my 2G A1 pad, the official ROMs are so bad!

I hope that 2G version ROM can make the rest 1GB space to /data

Issues found:

1. as talked, WIFI issues for 3 times on/off causes reboot.

2. front-camera reversal.

I found that A1's touch screen is not that smooth, sometimes even not accuracy, is this a hardware issue or ROM's, I found this on both CM7 and offical stock ROMs.
[Miscellaneous Android Development] terewong:

[Miscellaneous Android Development] gmarkall:
Wifi issue hack/workaround

After some fiddling around, as long as you run

echo 1 > /sys/class/rfkill/rfkill0/state

before turning on wifi, and

echo 0 > /sys/class/rfkill/rfkill0/state

after turning it off, you can turn it on and off as often as you like - in effect, this seems to solve the wifi reboot issue. I'm currently looking for the most sensible place to add this fix into the CM7 build.

EDIT: I'm just compiling and testing the fix. More news hopefully soon...

EDIT 2: After some very brief testing, the fix seems to be working. I've committed the code changes so the next nightly should have fixed and fully working wifi. Please let me know how you find it!
[Miscellaneous Android Development] wlmzfx:

I don't have any trouble with the touch screen on my A1, works exactly as I would expect.
[Miscellaneous Android Development] amjl2000:
Could it be said now that the remaining issues are all fairly innocuous and that as a fairly 'standard' user (imo) I could take CM7 and run with it without major issues?... it seems like strides are being made every evening now. I'm just waiting for the 'wow, everything is great now' before hopping on (I'm no tech expert so would not be able to offer much in the way of support, and don't want to brick my tab!). Seems like this may not be too far off now. gj!
[Miscellaneous Android Development] gmarkall:
The extent of my testing of the wifi was to turn it on and off about 10 times yesterday evening, and then a couple more times this morning (having left the tablet on all night without rebooting). So it's not thoroughly tested - when the next nightly comes out, we'll get wider feedback from other people who try it out, and we'll learn whether it's really stable or not (as stable as stock gets, anyway, since we're using the same wireless drivers).

There's very little chance of you bricking the tablet by installing CM7 - we don't touch the kernel or bootloader partitions when it's flashed, which are the risky operations to do when flashing stuff to the A1.

In terms of getting support with other issues and problems, I think that there's a lot of helpful people in this thread who are willing to provide advice and help. I try to respond to as many posts about issues as I can, but I don't get the time to do this to every one. If you do decide to take the leap to CM7, you won't be alone :)

android.location.Location.getTime() issue in stock firmware

Graham,

did you have a chance to look at XDA thread 1427788 (sorry, I can't post a link yet)? The A1 has the very same issue. Is there a chance to work around this problem in CM7?

It seems one can get reliable timestamps from the NmeaListener(), so the issue should be solvable.

Cheers
[Miscellaneous Android Development] gmarkall:
If you are comfortable with installing cwm 5.0.2.8 and the modified partition table then it will be fine to update to any version of the stock system, because that version of cwm can completely backup and restore the partitions that are overwritten by the cm7 installation.

If you only feel comfortable with installing cwm 5.0.2.7, then you might want to refrain from updating since I have only prepared a zip file that restores the stock ramdisk for 2375 (this is necessary as 5.0.2.7 doesn't back up the ramdisk).

Note that you can only install 5.0.2.8 and the modified partition table on the 16gb version at the moment.

Hi,

I'm not new in moding/patching etc. but i'm new with Android.

[Miscellaneous Android Development] amjl2000:
I am just starting to play with my A1 now that things are looking pretty good (thx all btw!). I read on one of teh otehr A1 threads here (can't remember which now) that someone has put 5027 onto a different version to 2375. Then, to go back, using the stock ramdisk for 2375, then using the official 2375 code, and then updating to 2643.

I am still a bit :confused: about what can be done with what, and how to do it. My steps so far are putting CWM5027 onto 2643. Then I have successfully backed up to sdcard, and then restored from sdcard. As far as I know, I can go back to my own backup at any time now, and ignore the stock code from Lenovo? If I take the next step to CM7, then my backup won't restore correctly as the stock ramdisk has to be installed first which is for 2375, so I will have to put an official 2375 on, then update to 2643, and then I can restore my own backup. Does this sound OK?

I'm reasonably happy to not have the stock recovery options available to me, which is why I put CWM5027 onto mine. Of course if I have done something totally :eek:, then feel free to let me know!
