.290 System Files - Create some custom ROM's [C6802 & C6806] - Sony Xperia Z Ultra

Here is the framework from the .290 update from Sony. (4.3)
It’s for anyone and everyone to use to make a ROM based on Sony’s latest firmware.
I've extracted it from a C6802 & C6806 base and uploaded it here for anyone to use:
C6802 LINK
C6806 LINK
Note:
1: This is not a ROM. However it’s everything you need to make one... except the installer script.
(The script = Recoveries use a script to flash the ROM)
2: Its not modified in anyway (remains odexed, and not zipaligned)
The purpose and hope, is that some of you will want to learn how to make custom ROM’s. It's not very hard and will just require a bit of reading, and some preexisting knowledge of linux would help…
There are quite a few tutorials on how to create a recovery script so use the 'search' feature within XDA as me positing another method would just be repeating what I've read & learnt. i.e. waste of time.

And here's a tutorial to make roms in windows without coding :thumbup: (credit @dsixda) http://forum.xda-developers.com/showthread.php?t=1272270
And potential rom builders, don't forget to grab the remount-fixed stock kernel that includes dual recovery (credit @ChillyChan). http://forum.xda-developers.com/showthread.php?t=2575909

Hey buz.. I put together a rom (not finished) but I'm in hospital at the moment.. Not serious, have an IV in my arm due to vomiting and diarrhea for too long . So I can't do anything else. Nice way to spend Xmas eh! I'll send you the Google drive link that I uploaded a few days ago as my backup. Let me know how you go. You'll need to flash the modified kernel.

@hamdogg bummer of a way to spend Christmas, hope you get those fluid levels up quickly! I've put all of boxing day aside for rom stuff so will have a look then (and watching Aussies smash Poms in the cricket) . Speedy recovery mate.

Thanks for the link,mate!
What about for those who wants to do some coding? I really want to do roms, but there are too many tutorials, so I don't really know where to begin. I've know some of C++. I guess that I need to learn some Java, right? Just tell me what knowledge are necessary to build a rom from sources? I really want to take part in porting GPE Rom to our devices.

its just the script you really need to understand.
the ROM tree like i've provided is just ripped straight from Sony sources. Not hard, just takes about 20 minutes.
The script is where the hard part comes. telling android to flash this and that, and have this partition for kernel, and recovery..
busybox and SU make is easy, but you still need to know how to execute commands in android/ linux.

ok, i'll bite
I've installed @dsixda's kitchen in my ~/dev dir, updated su,Supersu.apk and about to do busybox in the kitchen.
I've pulled apart @krabappel2548's omni rom and @hamdogg's rom to see how they are built, started playing with .290 and have inserted the duel recovery kernel from @ChillyChan
I might need a little help with the updater-script - will see how I get along...

Excellent... The update accept is the problem. My first attempt is in the cloud and I don't have access to download that amount of data. Buz days there are some errors, and he's having the same issues.

---

^^ busybox from the kitchen is one of the few things I couldn't get to work, it modifies the update script to make it work, but you'll need to review somebody elses rom's update script to get this to work.
Update script is where I struggle too btw.. I have been cutting and pasting from other roms update scripts to get it to work (incl. Z1 roms)
Good luck.
@hamdogg , would you like me to send @blueether a link to your dogg4 build?

Yeah sure. He can have a play with it. I'm away from my laptop for a while. Just me and the ultra. Well, and my wife..

Who wants to put money on me soft bricking my C6802?

---

^^ nah, dud roms just produce flashing errors more often than not.
Ensure you have an ext sd nandroid and can fastboot flash boot the @ChillyChan 290 kernel and recovery to restore said nandroid if required

yep have the 290 kernel ready and just completed a nandroid to the external sd card.
I'll have a look at dogg v4 first to see if I have really buggered up v0.1

---

The @Desperanto86 deodexed 257 rom also a good resource for checking for updater script clues

I'll see how this goes, just about to flash.
Most of the script looks good, not so sure on the final stages of setting up the /system...

Not bricked, but no go on the flash either: "Status 0", back to the kitchen I guess...
---------- Post added at 04:34 PM ---------- Previous post was at 04:15 PM ----------
got further that time: "Status 7" and a bootloop after about 30 seconds
---------- Post added at 05:25 PM ---------- Previous post was at 04:34 PM ----------
Soft bricked on third attempt... flashed dual kernel and restore... now building v0.5
edit:
Soft bricked again, with red flashing LED this time, getting better each time. I think it's time to stop for the day...
Last Edit for the day, I promise:
flashed kernel-dual.img back on top and it booted fine. I lost root but that was no big deal, just reflashed SuperSU. deodexed, zipaligned, nothing else done yet. But it is still my first rom.

OK, looks like I didn't deodex the rom properly (if at all), and now that I have I'm getting FC in settings.app
Is there a good reason to go deodexed?
I can't get root to stick in the rom, it works if I use either of the two 4.3 methods by @ChillyChan and @jackie099. Is there something else I have to do...? I guess I'll have a go doing it like @handogg and follow ChainFire's update-binary script

---

^^ I have deodexed zipaligned version of dogg4 that errors at the end of the flashing process - I can share this with you on Jan 2nd when I'm back online. Yes it errors but deodexed /system/app and system/framework may be of some use to you.
Btw, android 4.3 is api 18 and the kitchen defaults to api 17 (4.2) when deodexing - updating the api number to 18 in the kitchen "may" fix your deodexing issues
Re: a good reason to deodex? Most mods require deodexed rom is my main reason :thumbup:
