always on the bleeding edge here.... finally upgraded and 5 minutes later installed this kernel and successfully rooted. Woohoo! Still on RFS and no issues at all.

Thanks a lot and enjoy your Ice Cream! Do you anticipate any other development here?
[Captivate Android Development] mtcarey:
Great! Yes, there is a version 7.07 in the works, but I'm on ICS at the moment and need to flash back. I have a spare Captivate waiting for me which will make things easier, but I have to drive 50 miles to get it.

Cleaning init.d folder

I am trying to upgrade from 6.03 to 7.06 and have had reboot issues. I would like to clean out the init.d folder to see if that helps. I want to be sure not to delete something I shouldn't. Is everything fair game in the folder to delete. I am running FASTY KK4 and have 2 files in the folder, S08-zipalign-apk-sc and S50-vacuum-database-sc. Thanks for any assistance.
[Captivate Android Development] melvinaury:
I have the same issue, you can install version 7.0A. I install 7.0A and everything is working perfect. If you install by cwn the two files that you mention will be install again. If you install via odin the twi files would not be installed.
[Captivate Android Development] nycmon:
For some reason when i flashed back to 7.06 again ...everything works again lol....strange....but i will definitely keep this info for future reference! Thanks MT!

PS - wait I just realized I don't know how to even access the Android Terminal....Is this a built-in system app or something? Or is this done though the PC? Sorry about the noob question lol
[Captivate Android Development] shuyin1102:
The undervoltage settings also make the reboot issue. Make sure disable them before flashing a new kernel. The update script should be added to handle the UV settings and init.d

Android Terminal is on the Market.

Still loving the kernel.

I have a question about the efs backup. I can't seem to find the folder anywhere on my SDCARD that the option says it backs it up to. Time to get new reading glasses?
[Captivate Android Development] shuyin1102:
On mine the efs backup folder is "eds", i have no idea... you can use root explorer to manual backup efs
[Captivate Android Development] mtcarey:
Should be /sdcard/cwm5sc/efs-backup.
[Captivate Android Development] Red_81:
Okay, my glasses are fine. I'm not getting that folder created but the system toggle is on.

ROM: Legend ICS 3.4

Kernel: Corn 7.06

Filesystem: RFS

Overclock: 1.2

Undervolt: None
[Captivate Android Development] KMan94:
what are you using to create the efs backup?
[Captivate Android Development] Red_81:
I turned on the System Toggle in CWM to auto backup the EFS. It's part of the kernel options. I know I can do it manually and via other programs too. I just noticed this wasn't working and wanted to let MtCarey know.
[Captivate Android Development] bravomail:
I think I know why EXT4 doesn't work sometimes

I think I know why EXT4 doesn't work sometimes.

The problem is with EXT4 Journaling options in CWM.

Whenever I flash Corn 6, Corn 7.0A or Corn 7.06, it messes up EXT4 journaling options.

So I go to CWM section and turn journaling ON for all 4 partitions, clear cache, reboot, recovery - and voila - it's in OFF,ON,OFF,OFF with data-ON. But turning it on and off solves the issue.

Main symptom - unusually long media scan time.

So my solution for older kernels (not 7.0.6) - clear cache partition before flashing, turn journaling ON after flashing, reboot, make sure journaling is in OFF,ON,OFF,OFF with data-ON.

I'll test 7.0.6 now... Yep. It worked.

So:

clear cache, burn Corn 7.0.6

clear cache, turn journaling all partitions OFF, reboot,

clear cache, turn journaling all partitions ON, reboot

clear cache, turn journaling OFF,ON(data),OFF,OFF, reboot
[Captivate Android Development] Maxmusic:
You may be onto something here. I had no luck flashing any 7.0x Corn Kernels. Constantly had boot loops. I was able to settle in with 6.03. After reading your post I thought, is CWM really the problem? I decided to try SGS Kernel Flasher. Flashed 7.06 and a few minutes later I was up and running, no boot loops. Been on it for 3 hours now and still running smooth. I'm thrilled you came up with the idea of CWM maybe being the culprit. Maybe others will have luck with SGS Kernel Flasher. THANKS!

[Captivate Android Development] KMan94:
I used Odin and then rooted stock KK4 with 7.06. I did not convert anything to ext4 nor have I changed any default settings. Not a single reboot.

Every so often I get both the wireless icon and the 3G icon displayed when previously if wireless came on the 3G icon would go away but that is the only anomaly I've seen.
[Captivate Android Development] tamanaco:
I'm using Illuminance 3.01 with CK 7.06 using EXT4 partitions and was about to try a new ROM because of random performance issues and reboots. After trying the steps that bravomail suggested the phone has been more stable and responsive. At least all day yesterday. Now I also believe that he might have found an issue with EXT4 partitions. If there is a new CK release in the pipeline, the developer should consider looking into what bravomail "might" have uncovered here.

Edit: Two days and only one reboot, yesterday, soon after I changed the OC setting to 1200Mhz... Today the phone is still at 1200Mhz with SIO and SmartassV2 and no reboots for over 20 hours.
[Captivate Android Development] ccheung:
I flashed 7.06 over saurom. It works fine until i use titanium backup. The titanium backup has a message alert saying the su is out dated and asked me to update it. I did, then i cannot write to sd storage. Any fix on that?
[Captivate Android Development] ctrclckws:
Titanium backup has an option to turn off that check. If it works otherwise...
[Captivate Android Development] poetikal:
I don't want to sound noobish with this question, but I can't seem to find how to OC in Recovery. I've been using Talon for almost a year and half and never went to a new kernel. (BTW I love this kernel... it's so buttery smooth and awesome!)

Thanks for any help. :)

EDIT: Forgot to say which one I'm on. I'm using 7.06.
[Captivate Android Development] -Thrive-:
In recovery:

Reformatting, tweaks and more/Tweaks and settings/misc. system toggles/overclock to 1200 OFF/ON

Also, you can use Voltage Control from the Market
[Captivate Android Development] poetikal:
Weird, the option isn't there. I did use Voltage Control before, but it only showed 1000 MHz. I'm going to reflash and see what happens. Thanks though for telling me where to find it. Appreciate it tons!
[Captivate Android Development] prbassplayer:
Are you sure you not using 7.06A?
[Captivate Android Development] poetikal:
Nope, it's regular ol' 7.06. It's fixed now. I used the ODIN version to install Legend 3.4 ROM, and I'm guessing it didn't give me OC options. I reflashed using the CWM version and low-and-behold it appeared. It's all fixed now.
[Captivate Android Development] KMan94:
Minor bug

I found a minor bug today. When I open the app drawer holding the phone upright and then turn it on its side, all the apps gather up into the right hand corner. If I tap the screen they all go to where they should. Odd and not at all that important but weird.

I am using Launcher Pro and I have the 3-D option enabled. Stock KK4.

Not complaining, just reporting.
[Captivate Android Development] KMan94:
I'm going to flash a new ROM that already has 6.03 (Legend 3.4 stock). My question is, is it better to flash 7.06 with Odin or CWM to get back to 7.06. I am currently using 7.06.

I ask because there seems to be some differences noted in the OP.
[Captivate Android Development] robm1911:
Actually the last time I did a full wipe on Legend (last week) I used sgs kernel flasher to flash 7.06 so I could back up the 6.03 that comes with the ROM. Like I said been rollin a week, and no issues..
[Captivate Android Development] crt60:
I flashed 7.06 using odin and I have had no issues either, seems cwm maybe the culprit, going to do a test to see how well it does flashing with a rom. Might go ahead and put it in the next release of Legend.
[Captivate Android Development] Red_81:
I've used 7.06 on two different phones with the last two versions of your ROM and have 0 issues that I can relate to the kernel. If you use ext4, you need to check your journal settings, though.
[Captivate Android Development] crt60:
I haven't had anything major with 7.06, just some strange anomalies. I had the phone, just out of the blue while sitting there, dial my voicemail. And other times, apps would just disappear with no errors or fc's while I was using them. I never had any of these things happen with 6.03, and haven't had any when I flash 7.06 with odin. So I can't say any of these things are related to the ROM when they have only happened when I had 7.06 installed with CWM.
[Captivate Android Development] robm1911:
Curios though, how were the 7.06 kernels flashed, with Odin or cwm?

@ mtcarey. Sorry bro not trying to jack your thread, just trying to dig a little deeper at a possible cwm bug.
[Captivate Android Development] aww.W.T.F?:
I used cwm to flash 7.06 2 weeks ago and have has zero problems. I'm only 3.0 though, not sure how much difference there is between 3.0 and 3.4.

If this makes a difference I used odin to install 7.0 first then flashed over that.
[Captivate Android Development] KMan94:
I used Odin the first time. Right after I used Kies to upgrade and then I rooted. Never had a problem with it. on 6.03 at the moment though :)!
[Captivate Android Development] Red_81:
Good question..... I actually did it both ways.

I would flash it first through ODIN from stock KK4 to get CWM. From there I would flash Legend, but then go back and flash 7.06 with CWM (Since Legend provided an older version)
[Captivate Android Development] joelpt:
TL;DR: 7.06-CWM has Wifi issues, flashing 7.06-ODIN fixed it.

I was having an issue with Wifi using Corn Kernel 7.0A while flashing SimplyStock 1.5-KK4. Specifically, when turning Wifi on, the phone would do 'scanning' for wifi networks, then after 10 seconds would just disable the Wifi again.

So I flashed Corn 7.06 using the CWM zip/method. After doing so, the Wifi scanning started working and was not shutting itself off. However, a moment after authenticating and obtaining an IP from a given wifi host, it would 'quit' that connection attempt and start authenticating again in a loop.

Finally, reading the posts here, I flashed Corn 7.06 using the ODIN tar/method. Upon booting, the phone can now connect quickly to a Wifi network, transfer data, and works just dandy.

So, it does look like the CWM method exhibits certain Wifi-related issues which the ODIN method does not. Strange stuff.
[Captivate Android Development] crt60:
Another possibility is it could be redbend_ua, that is what is doing the actual flashing. Not cwm.
[Captivate Android Development] KMan94:
Something broke...

I just Odin'ed 7.06 over Legend 3.4. My pull down has gone away. I can't see the time, any of the icons either. And, when someone calls me I can't answer the phone. It did work with 6.03 that came with Legend. Not sure if here is the correct place or over in Legend but I could use some guidance.

Also, when I plug it in, I don't get the screen that give me the option of mass storage etc...

reflashed 6.03... didn't work....
[Captivate Android Development] crt60:
Not sure what happened there, doubt it is the kernel, prolly shouldn't jack this thread and should move to the Legend thread.
[Captivate Android Development] shuyin1102:

Rogers UXKH2 getting Corn injected ?

mtcarey,

First of all, fantastic work. Corn kernel makes everything so easy and so smooth. I notice the difference right away. So thank you for putting the time in to this and thank you for sharing.

I apologize if this has been asked or if this request is out of place, but is it possible we get Corn awesomeness injected in to the Rogers UXKH2 kernel? I have tried the KK4 kernel with the Rogers 2.3.3 ROM and for the most part it works. But there are inconsistencies left over that make it annoying enough.

Actually, my hidden request is some guidance on how to integrate the changes to the UXKH2 source and building, I am a newb, but am trying my best to learn how to build and customize kernels.

Thank you kindly for your time and consideration, any hints or pointers to instructions would be greatly appreciated.

Fantastic kernels! Still looking for some posts to read about rfs vs ext4 journaling, governors, and schedulers -- and thanks for posting links to read on the OP. Helps A WHOLE LOT for a noob like me
[Captivate Android Development] Richdd:
Hello. I'm looking for some guidance, or any other info.

I'm running Corn v7.06 (very happy for the most part) w/Legend 3.4.

Found an issue when attempting to load Gallery, the phone goes to a black frozen screen. Sometimes I can go to "home" and start over. Only for it to again go to a black frozen scree. And some times the phone just reboots.

I went to recovery, then down to "Reformatting, tweaks and more". Then "tweaks and settings", then "Scaling Governor". I reset my phone to "Performance" and reboot the phone. Now I am able bring up the Gallery with out issue. Can someone give me some insight to these settings? And the differences between the other settings?

EDIT

After playing with a few of the settings in "Scaling Governor" I found that "ondemandx" works the best with this phone so far. The games do not lag, or hang up ("Blood & Glory" is one game), and Gallery opens right away. Even after other apps have been opened, and closed. I also found that Facebook loads faster.

Wow! I've been using Corn 7.06 with the Legacy ROM for about a month now. The slight instability issues were tolerable. This morning about 1am, my phone went into a re-boot loop. Every minute or two, the phone would just reboot. I then flashed Cog 5, to be sure it wasn't the phone. As I thought, it was Corn 7.06.

I then downloaded, and flashed 7.06A. And again, reboot loop. Is there any fixes? Can anyone help? Please :(

I too am using 7.06 with Legend. Until recently it has been rock solid but in the last 3 days it has rebooted 4 times during a phone call. As embarrassing as it is annoying.

I do have it overclocked to 1200 and am running sio and rfs4. The overclocking is the last thing I did to it about 2 weeks ago.

Thoughts?
[Captivate Android Development] Richdd:
I had the same issue. Found it to be swype. Swype looks for updates. And for some reason, it's messing with the Kernel. I used Titanium backup to uninstall Swype, then reinstalled swype with the swype installer. Hope this helps.
[Captivate Android Development] Richdd:
Yes. I don't think it was Corn. Check out the post above....

[Captivate Android Development] KMan94:
I don't use swype so probably not. I did back the overclock off so we will see. I'll back things down one at a time until it goes away. I'll post the results here.

Hello Mtcarey!
[Captivate Android Development] -Thrive-:
I also have been using 7.06 with Legend 3.7 and recently experienced call drops, music stutters and app and keyboard closes (I don't use Swype, I use Perfect Keyboard). I started turning off tweaks and OC but it still kept happening. Yesterday I used Font Installer Root to change my font and my phone wouldn't boot. Got it to boot without wireless or phone but couldn't revert because the app was doing a call home before it would load (garbage, will never use again). I ended up doing a complete wipe and factory reset (first in ages), installed Boog's

KI2 Rom to recover and then went back to Legend 3.0 and Corn 6.03. Phones never worked better so I'm staying there. Not sure if something was introduced in later versions of Corn or Legend (going to 3.7 was the most recent change), in tweaks I have used, or maybe I just needed wipe/factory reset.
[Captivate Android Development] Richdd:
G

Had those kind of issues with Legend 3.4 on Corn 7.06. Dropped Legend 3.7, onto Corn 7.06,and now very happy with Legend.
[Captivate Android Development] crt60:
Just curious, did you have ext4 enabled? Cuz I've been using 7.06 on rfs and no major issues so far. Running tests to see what maybe causing it. I've had no issues at all with 6.03 but 7.06 is much smoother even on rfs.
[Captivate Android Development] -Thrive-:
Yes I had EXT4 enabled for Data, DBData, and Cache. System was RFS. I have been running this way for several months and initially very stable. The only recent mod I did after upgrading from Legend 3.0 to 3.7 (non-wipe) was create a battery mod using UOT Kitchen with the framework.res.apk from 3.7. I think this mod may be what got me into my initial problem with Font Installer. I think the some of call drops and other instability began before upgrading to Legend 3.7 but definitely got worse after. That's the risk of doing non-wipe ROM upgrades.
[Captivate Android Development] crt60:
EDIT:

Robs been doing some intensive testing and he found that flashing a new full wipe ROM on a clean ext4 partition is the most stable way to install on ext4. Format partitions using ext4 full wipe with no backup/restore. Then immediately after, flash your full wipe rom directly over the top of ext4.
[Captivate Android Development] -Thrive-:
Thank you for the recommendation. I think I will stay on rfs and reapply the upgrades soon.

7.06 causes random reboots. 7.0A battery life is lame. 6.03 seems to be the all around best so far? I've tried with stock KK4 and SimplyStock. Anyone else?
[Captivate Android Development] crt60:
I don't know, I think you have to see Corn 7.06 for what it is, its a high performance kernel with lots of options, I found that it runs great on an rfs filesystem. Its one of those things, you want to flash everything new, install what you want and just use the phone, if you keep flashing themes or making other major changes to your ROM then I wouldn't recommend it, if you are going to set up your phone and just use it, I think it is a good performer. My cappy has never run so smooth as on 7.06, granted 6.03 is workhorse, and is very stable, you just have to treat the 7.06 kernel with kid gloves and respect, and it will serve you well.

Just my 2 1/2 cents:D
[Captivate Android Development] tamanaco:
I'm using 7.06 with SimplyStock, but initially I had issues. I decided to go back to stock and rfs before installing SimplyStock 2.0 and Corn 7.06. Making sure to install 7.06 using odin while still on rfs. Then converted all partitions to ext4 with Journaling turned on in the Data partition only. Now I rarely get any random reboots. Once in a while Google Maps closes without any errors when I try to use the search function within it. But... I "believe" this is happening because of a low memory condition. This happens using the default settings for Corn and also with my favorite performance settings SG=SmartassV2 and LMK=60GB. Recently, I started playing with Auto Memory Manager to help me determine the number, size of memory being used and priority settings (foreground, visible, secondary, hidden, content and empty). of all applications that are currently running.
[Captivate Android Development] c0ldburn3r:
I've long since moved on to the sgs2 but I still use my cappy for media. Personally I've found the kk4 base roms are crap. The old girl is back on cog 4.5.3, in fact my wife's crappy is in worse shape and I've never touched it. Picking up an sgs2 for her next week.

Battery drain

Not sure if this is related to the Corn kernel, but I noticed a real runaway battery drain today. Normally I charge my cappy overnight and reboot it immediately after unplugging it in the morning. Today I didn't do that and noticed my "Google Services" and "Android Core Apps" were using juice like mad.

Google Services 53%

Android Core Apps 27%

Cell standby 6%

Display 5%

Voice calls 5%

Phone Idle 3%

Took me to 35% battery in just over 6 hours (because I didn't notice it before that). Could that be kernel related or more likely some rogue app (which appears would be Google-related)?

I'm using 2.6.35.7-I897UCKK4-CORNv706 on SERENITY KK4 6.3 FINAL

Edit: And now today I've noticed that my screen isn't turning itself off after one minute like it always has. Related? Maybe it's time to go ICS.
