Default [Q]CF Root, how dangerous is the lagfix?

Hi,

I recently downloaded and flashed the CF Root Kernel v2.9.
I'm running an Android 2.3.3 ROM (Lite'ning rom v4.2).

Now I have been hearing things about how the Lagfix on the CF Root kernel is potentially dangerous. Apparently it corrupts your system when you disable it and switch to another kernel.

I am wondering how true all of this info is and if there would be any danger in flashing to another Kernel/an update of the CF Root kernel.

Any help would be appreciated,
Hobo

PS: Had to post here as I need 10 or more posts to get access to the Development forums...

1. where did you hear that the CF Root kernel is dangerous? Links please

2. apart from the fact that the stock kernel from gingerbread has already ext4 support means all hacked kernels should have it too, and also apart from the fact that CF has a nice tool to convert back easily.
If you are already on a custom kernel and you wanna experiment more, you do know you can backup right?

hmm, am interested on what you mean with the breaking system? you mean fs? or it breaks something else?

^ don't have that phone anymore, too lazy to change the picture...

htc One X
CM10.1 -ncx_314_vxx - variant 0
echo 0 > /sys/class/leds/button-backlight/brightness
chmod 444 /sys/class/leds/button-backlight/brightness
echo "who cares, always changes with the kernel..." > /sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table

Quadrant score never matters!

1) I heard it on a forum for Dutch Android users, Androidworld. More specifically on the Lite'ning rom topic, I can't post a link (see edit) but since all posts are in Dutch I'm not sure it would be helpful for you.

2) Yes I know I can back up, I have everything backed up. Just a bit worried about my phone not working for pre-longed periods or having to go to a Samsung repair point.

3) From what I gather the problem is that when you convert to Ext4 (or convert back) it doesn't completely overwrite the /system/ which makes it so that if you decide to switch to another Kernel it becomes impossible to activate the lagfix and you might get the warning your system is corrupt.
Most of the posts link to an old topic of Supercurio and Voodoo about lagfix corruption (can't find the link right now...)

The problem seems to be solved after reflashing a new ROM with repartition.

/edit: "To prevent spam to the forums, ALL new users are not permitted to post outside links in their messages. After approximately eight posts, you will be able to post outside links. Thanks for understanding!"
So the link isn't a hyperlink.

Well I kinda wouldnt call it a lagfix now. I mean its a switch to another fs.

And I think you got the fixing part about reflashing right. So if you have a backup (also go with titanium on this one) . If you reflash you get your system back in a jiffy. I mean its like 30 mins reflash and initial setup right? And then 15 mins to get the backup online (just to scare you a little and to save my ass from being kicked, if something goes wrong somewhere along the line you have been warned that this can do something bad to your system in a 0.1 percent chance)

Anyway first thing you can do is to reflash to the version 3 of CF

Which kernel are you interested flashing to? (oh and one thing if your rom came preinstalled with busy box and you didnt unistall it and flashed CF on top of it, you can have some trouble)

htc One X
CM10.1 -ncx_314_vxx - variant 0
echo 0 > /sys/class/leds/button-backlight/brightness
chmod 444 /sys/class/leds/button-backlight/brightness
echo "who cares, always changes with the kernel..." > /sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table

I thought Lagfix pretty much ment that... Shows how much I know about all of the terms

I was probably going to go back to the Hacked Supercurio kernel.
I am not sure if the ROM came pre-installed with busybox but I assume it was since it was auto-rooted.

Didn't really want to go flashing as I'm always scared of bricking but here I go!

Thanks for the help

Was planning on flashing back to a 2.2.1 ROM with repartition, then flashing back to the original ROM which comes with Supercurio's Voodoo kernel.

(and thanks :P)

Btw with that term lagfix you were right. All call it that . Just for example nexus S has ext4 as a stock fs. So thats why I said in the future it could be just called converting the fs. Also the rfs isnt so lag plagued in the late 2.2.1 and for sure not in 2.3.3 versions. Thats why no lagfix.

One thing though when you say original rom wiht supercurio kernel what you mean with that?

Oh and have you tried JVK?

For some reason the ext conversion did a lot for me.
Mostly in start up speed after sim-card unlocking.

With the original rom I refer to the un-updated custom ROM I was running when I flashed the CF-kernel.

Haven't tried the unmodified JVK but the ROM is based on JVK
