[SOLVED][Q] Help writing updater-script (set_perm, symlinks) - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

Hi guys,
I just tried to build my own rom from the Android 4.2 system dump, but I don't know how to write a real updater-script.
I took update-binary from FXP (not sure if I'm allowed to, so could someone tell me if I could use it?) and tried to write my own updater-script. It's looking like this:
Code:
mount("yaffs2", "MTD", "system", "/system");
ui_print("System mounted");
show_progress(0.500000, 0);
format("yaffs2", "MTD", "system", "0", "/system");
ui_print("System formatted");
mount("yaffs2", "MTD", "system", "/system");
package_extract_dir("system", "/system");
show_progress(0.100000, 0);
unmount("/system");
but after that it's not booting. Could be kernel related, too, that FXP 145 kernel is not working, but maybe something other is wrong.
What about these set_perm lines and symlinks? How do I know what I have to write there?
And how can I know where my rom stuck, if it is kernel related or what. Tried to logcat but logcat doesn't recognize device?!
Maybe someone could help me :good:
Best regards
Mihahn
Edit: Looks like I'm not able to build from a system dump and now we have Cyanogenmod 10.1

Okay it looks like it's not a rom problem, if someone knows how to compile a kernel for the rom it would be nice if he could post it here or PM me, that he makes the kernel and I the rom.
It's a kernel problem I think, because it stuck on the FXP 145 kernel logo...
Would be nice if you could help me to compile the kernel for the rom!
Thanks
Mihahn

A Rom based on 4.2 ?? Wow

Without setting proper permissions your Rom will not boot at all. Try using the META-INF folder from fxp cyanogenmod 10 Rom it should work (probably) and moreover in my personal opinion the kernel shouldn't be the problem because 4.1 to 4.2 is not a big leap and so 4.1 kernel would be sufficient.

MetaInf folder from fxp gave a set_perm error, that's the problem and I don't know which values I have to edit to get the symlinks and set_perm working...

Okay, this is how I debug updater-scripts,
Add,
ui_print("1");
Click to expand...
Click to collapse
Before first set perm command then
ui_print("2");
Click to expand...
Click to collapse
Before 2nd set perm command and so on till the last line of code in the updater-script and you'll know after which line the error occurs and can look into that line of the code . It might be tedious process if your updater-script is loooong but it always works for me!

Yes similar to this I have done it, too. Changed some lines now and it's working very well with the updater-script by FXP :good:
Now my problem is, that it's not booting. The kernel logo appears, the led for cwm lights up, i wait, The led goes off, screen gets brighter, but the kernel logo stays.
Someone has an idea how to get it booting?

Which system dump are you using? Lg Nexus 4? Anyways, porting Rom is not piece of cake. Read some tuts, play with the system files and you might see the bootanimation sometime soon :thumbup: and even though I said kernel might not be a problem it might be actually a problem

Yes from the lg nexus 4. I think the problem is that the rom is odexed (nearly all apks had an odex file, too). But not sure...
Read many tutorials and I've already done some ports and roms and nearly all of them are working...
Have you got any other idea what I could do to get it working?
Maybe I should wait until the first official repos are released and then start to work from source...

I've never done any ports or some thing like that (not much free time) hope you'll succeed soon :thumbup:

Thank you, I hope somebody could help me, any developer who could take a look on the rom and the updater script and maybe build a kernel to the rom...
Would be great to have an Android 4.2 rom before the sources are officially released (on the 13.11.?)
Haven't got much time, too, but when I have time I like to port roms or build my own ones :good:

It looks like the nexus 4 is a xhdpi phone isn't it compulsory that you resize each and every image inside every apk to mdpi resolution including the boot animation?? And can you get a logcat right from the boot (pastebin)?

I don't know, but I think there are really some things to do, so I think I will have to wait until the sources are released and I will try it again...
Thanks for your help

But not every file was odexed, just these apk files had an odex files, too. In my rom I just deleted all .odex files. Maybe that's the problem?

hey! you shouldn't be deleting the odex files without deodexing! that's a major mistake!
by the way i deodexed all apks in /system/app and now working on /framework (i do it manually, i prefer that way) :good:

---

Okay I've fully deodexed /system/app and /system/framework but I'm getting error in deodexing core.odex can you try deodexing core.odex and tell me?

How did you deodex manually? What steps have you done, are you using any tools or how to you do?
