[Q&A][OFFICIAL] CyanogenMod 10 (JellyBean) Nightly Discussions

[anactoraaron]

I'm glad you mention this. It doesn't always do it to me, but it started when I flashed 10/22. I'm thinking a factory reset and clean flash is in order, but when I tried that last night none of my market links worked. All my paid apps weren't marked as "Purchased", rather with a price tag, and the My Apps section was empty. Thank God for backups.

I've had this happen on other devices running CM. Usually all you need to do is clear data from the play store.

I have done straight dirty flashes since it was unofficial... no issues. I haven't even had a SOD in two builds. Love it...

Interesting, it seems that the nightly goes live at the same time every morning (7:00AM CST) but my phone is unable to download the update until about an hour later.

Edit /system/etc/vold.fstab changing:

#internal sdcard
dev_mount sdcard /storage/sdcard0 28 /devices/platform/msm_sdcc.1/mmc_host/mmc0/mmc0

#external sdcard
dev_mount external_sd /storage/sdcard1 auto /devices/platform/msm_sdcc.3/mmc_host/mmc2/mmc2

to

#internal sdcard
dev_mount sdcard /storage/sdcard1 28 /devices/platform/msm_sdcc.1/mmc_host/mmc0/mmc0

#external sdcard
dev_mount external_sd /storage/sdcard0 auto /devices/platform/msm_sdcc.3/mmc_host/mmc2/mmc2

That's what works for me. Otherwise the internal sdcard never mounts.
Also keep in mind after every update you'll have to redo this, as it will be overwriten.

Just installed the newest Nightly (10/25) and now my phone won't boot. I get to the CM boot animation, but it just spins indefinitely. I don't get an adb connection, so how do I boot into recovery to revert?

Pull battery and hold vol up down and power then when Samsung screen goes off release power count to 5 and let go of vol up down and recovery will start

swapping mounts...

Guys, I know you would like to have more space for the important stuff, but I think swapping the mounts is a bad idea.

I think I may have an alternative though: symlinks. Figure out which particular directories you'd like to store on the SDCARD versus the local phone storage, and then symlink those directories.

I'm pretty sure this would work, and this method would survive upgrades, hell... even data wipes. And best of all, it'd be safer.

I'm gonna investigate and put up some pointers.

.

dr4stic, while I agree from before that swapping the mounts via fstab is not ideal, in my case, and I can only speak for my case, it is the only way to get CM10 working. The 'internal sd' just doesn't mount on sdcard0! It sounds like there are other folks here that have had that issue, but definitely not all.

As far as symlink vs mount, how is that safer regarding data wipes? When you boot in CM, it still thinks sdcard0 is the internal memory so it never touches your external card.

Ideally CM10/android should offer an option to select the external SD as main storage (like in CM9, which I still believe does just that- change the mounts), until then I really don't see a problem swapping the mounts.

 

[mdneilson]

Symlinks won't work, both cards are fat 32 which doesn't support symlinks. Plus, if the external sd was removed, then files sent to the link would become lost. Here is a small script that will mount folders if the cards are present and mounted. I modified this from another xda post, just paste this into scripter and set to run on boot.

 #!/system/xbin/sh

# Check if the SDCARDs are mounted yet.
result="`ls /sdcard/ | wc -l`"
while [ "$result" -eq 0 ]
do
    sleep 10
    result="`ls /sdcard/ | wc -l`"
done

result="`ls /external_sd/ | wc -l`"
while [ "$result" -eq 0 ]
do
    sleep 10
    result="`ls /external_sd/ | wc -l`"
done

# The cards are mounted. Now mount the directories
busybox mount --bind /sdcard/test /external_sd/test

Looks like posting from android messed it up. I'll clean it up when I get home

Edit: never mind

Ya symlinks won't work I've tried... > there is another option its called directory bind and that is and app that takes a directory and binds it to another so u can download asphalt 7 for example its 1.4gb which is our whole internal sd and u bind it to a directory on the external sd and then it moves the files to ur external sd but it shows as on ur internal so when u run the game it runs from ur external but the problem is u have to have enough Room to download the app or game so thats why i swapped mount points here is the thread i started that will allow u to do the same its as easy as swapping 2 numbers in Vold.fstab in /etc

The directory bind thread is just a Google search away if that's what u need too

Directory bind does the same function as the script that I posted. It is a simple bind mount. I hate having apps for such menial things, but it is simpler for those who don't want to go through the work. Bind mounting should download directly to the external card if the mount is successful.

I knew I should've checked the filesystem before opening my mouth

I just assumed it was ext4, not sure why they would format an internal partition as fat.

Would Super apps2sd be of any use? http://forum.xda-developers.com/showthread.php?t=1888986

2 quick questions for you.
Have the changes from 10/24 unofficial been pushed to the official nightlies?
In performance settings do you recommend turning on ksm and zram?

ksm, not sure. It does look cool. You could try it and report back

As for zram, seems like it'd almost necessitate more CPU all the time, right? The device has 1gig of ram... are you memory starved? If you need the memory and are willing to sacrifice cpu and battery for it, then go for it. But I don't think the majority of people will need it.

I used to use ksm on my old phone and it helped on some processes.

I'm not starved for memory and most people will stay away from zram..

Have the changes from 10/24 unofficial been pushed to the nightlies ? Thanks for the quick response

Random MAC address fix???

I've been happily downloading the nightlies each day and continue to be impressed by them- the stability and battery life keeps improving...BUT the one continual pain is the random MAC addresses generated by the wifi!

All the access points where I work (as well as my own ones at home) are set up with MAC address filtering so this effectively means I have no wifi. I can reset my home router (though this means changing the set up on all my laptops, desktops, bluray player, Wii etc.), but that doesn't help me at work.

Does anyone have a fix for this that I can use until whatever needs fixing gets fixed in CM10? Something I could flash over the ROM or an edit I can make in the system- I'm really not complaining- I love these ROMs, but this is getting to be a dealbreaker
