Hey there, as I said I was a bit put these days, but I took a look at this flashlight app that works, which is great!. I will like to aske [MENTION=2555984]IvcH[/MENTION]eck to tell me what he did. As far as I know, I decompile his app and compare to mine, and this are the changes he made:

New one with changes:

https://github.com/broadcomCM/andro...lay/packages/apps/torch/res/values/config.xml

This one is he old one we got:

https://github.com/broadcomCM/andro...lay/packages/apps/torch/res/values/config.xml

Here is the commit, but I forgot to delete ~ which commit becomes kind of mess.

https://github.com/broadcomCM/andro...mmit/5696ab3760c717a960e82af9935d9afc98afd0b8

Well, please contact me and tell me if this are the changes you made, or you made more. I'll like to fix torch from source, not placing the apk, if you are a developer you will know why ;)

Thanks again, bieltv.3

Not to burst anyone's bubble, but that requires some serious reverse engineering even developers with more free time and experience (as in, it's directly related to their field of actual work/studies) can't do before months.

Do it through ODIN better... :) Hope you can install it soon.
[Galaxy Ace S5830i Android Development] bieltv3:
Well Guys, new thing to tell! I've builded my first booting kernel. I must thank alot Lopicl.00 for guide me during all the process. Many people asked me, why don't you join lopicl.00 to make the kernel. The purpose of the kernel is different. Of course I'll help him and he will help me. I fixed WIFI on CM in his ramdisk, he teach me how to build the kernel. Prototype-U help both of us! We are great partners. But with diferent purpose, lopicl.00 wants to make a kernel, a good kernel, that performance increase, you seem that you have his kernel. Mine is different, mine is based on just Samsung sources, whithout lots of scripts, just a base kernel, to work 100% with CM. Then kernel developers, like him, will take my base and increase it, of course they will do, but I want to write first the base.

SO here we go, stock samsung kernel, with LZMA ramdisk supported on CM7. Next step for tomorow, bluetooth...
[Galaxy Ace S5830i Android Development] atometros:
Ok, the kernel I flashed was the one Biel mentioned on the instructions for flashing ( http://xdaforums.com/showthread.php?t=2253010 ). And the wifi didn't work. Any possible solutions, or perhaps a problem with the phone? :confused:

[MENTION=4686683]bieltv.3[/MENTION] Hey I saw your logcat in the sgy section and the line which caught my eye was this :

I/brcm_patchram_plus( 2238): file /system/bin/BCM4330B1_002.001.003.0634.0652.hcd could not be opened, error 2

Which obviously means that your patchram is unable to find that file. To fix it you have 2 options:

1.Change the ramdisk to load the correct file which is BCM4330B1_002.001.003.0609.0614.hcd

2.Rename the file BCM4330B1_002.001.003.0609.0614.hcd to BCM4330B1_002.001.003.0634.0652.hcd

This will remove that error and most probably BT will work.
