porting roms from s3 i9300 to i9305 - Galaxy S III Q&A, Help & Troubleshooting

hi im currently in process of porting a stock deodexed rom.
i have changed system files and the update script.for out i9305. at moment i am able to install the rom fine and loads up with or without wipe. i also included the ee modem.
my issue is that when the rom starts all is ok and there are no force closes however i get no network and imei shows null. to resolve this i just flash param.tar in odin and stock file and all is back to original with imei restored.
any ideas on whats causing the loss of imei number
in setting imei and baseband showbas unknown
edit whilst restoring to stock i did not have to restore imei backups so am asuming efs part is fine

i am really into this thread. I opened a thread similar at the beginning but they moved it, hope this one stays in here otherwise it will get lost in the i9300 section...... this is really good lets all try get into this, like i said I am going to play around on monday when i return home, so far we got everything going exceept the Modem is not connecting to the Imei correctly, We need an experienced dev.

Try merging our system and framework so it picks it up as our xxali5 or xxali9 you have to get rid of there base and put our base instead but leave the edited files so maybe the system apps folder stays the i9300 as the apps are the same i think but change the rest into our firmware hmmmm so maybe a better idea would be to have a blank deodexed and zipaligned xxali5 rom move and overwrite our files with the edited files of the i9300 that way all our efs and imei doesnt get touched

Great thread, wish I could contribute more.
At the moment I'm hanging to see what the more clued up guys around here work out!

Basically there are some intensely different changes within the services.jar, framework.jar, android-policy.jar and so forth. 4G LTE is sooo much different than the stock i9300. I am not saying it CAN'T be done. But I am saying it is going to be a complete bastard to do. Put it this way, you'd be better off looking into all of the modifications that have been done to create these ROMS and re-doing them to the i9305.
Trust me, I have looked into doing this with a "customised" build to from sources for ICS for the P7320T tablet that I had. It is the only 4G tablet released here in Australia. The closest I could find in sources for being able to make the connection was grabbing settings systemUI and the others I have listed above ^^^ from the S2 4G LTE. Then I was going to have to modify the systemUI specifically for tablet mode.
I no longer have the tablet nor the patience to want to take on anything like it again.
All I can say is good luck. Feel free to check my threads to confirm that my choices are not a conflict of motivation or lack of determination...god I can assure you that much
Just for a tip. I started today with decompiling the android-policy.jar file to see if I could enable the torch app double click home from lock screen feature....this has been done on i9300 right? Go take a look at the full guide on how to do it...go decompile 1 file that I am talking about and you will see just how different the methods are in all of the smali code. JOY!

What tools are you using to "port" this ROM to our device?
I have tools that can port ROMs in about 30-40min.
What have you got in the build.prop for this thing? Do you want to upload the ROM for me to take a look at? The least I could do is offer some help before raining on your parade lol.
Have you considered doing maybe a "splice" of the ROM. Rather than porting the full version, you could do a diff/compare of the modded ROM against it's stock counterpart. Then you migrate those changes over to your "stock i9305" base. That is going to be your best chance of doing this I reckon? also you won't be able to copy across the firmware version. That won't work. Your framework and the firmware version are going to be device specific.
The absolute best thing I can think of suggesting is to go with a known base equivilant?? Like it seems that there is a release of XXALI5 (for touchwiz at least?) on both devices. That would be where I would start first and foremost. I would port with that common version using what I described above and then migrating any further or additional functionality (developer made i.e. Wanams mods) that have been done since the XXALI5 release.
That is going to be your best bet.
Or you guys could just wait for me to release my ROM haha...subtle promotion? I think not.

Exactly
I have a methodology that does this very easy. I wanted the OP to upload his work so far to save me a download. But I might just go ahead and do it anyway.
Have you guys got permissions from Wanam to use his work? I will ask on your behalf if not. He is a great contributor to this forum, I don't wish to have him offside.
What I mean is that I will go ahead and play, but I won't re-upload any test files to the forum without his consent This shouldn't be too hard

Contacted Wanam. I will wait to see what he says and recommends. I have claimed I am not releasing anything of his, so this can be owned by you guys who want it. I am happy to help get the ball rolling to help yous though. I have my own dev team that I work with so that makes me kinda busy. That is why I haven't released my own ROM on here yet lol

Downloaded XXLAI5 Wanam, Downloaded XXLAI5 stock i9300, have already downloaded XXLAI5 stock i9305 and I am currently deodexeding it as we speak.
Will deodex i9300 XXALI5 next and then do a comparison to Wanams. Segregate changed files - > port to stock deodexed base = Wanam i9305 for you guys
That's if Wanam approves of course?
EDIT: Hey Mr OP can you please contact me? I cannot send you PMs? Holy smokes you've been around this place since 09!

---

Ok Analysis done on Wanam compared to stock XXALI5 and have all the of the files seperated and within their directory structure that had changes.
There is going to be some work needed to be done on these main files:
/system/framework/android.policy.jar
/system/framework/framework2.jar
/system/framework/services.jar
/system/app/systemUI.apk
As I expected
Now the fun n games start I will decompile all of these files and then diff them against the standard i9300 smali coding and then *attempt* (and I say that with all great intension too) to migrate the changes across into decompiled i9305 files.
I can tell this is going to be a head ache!
Otherwise though....I can honestly say that what I have got so far I know for certain will boot and you will not have baseband issues. You won't however have 15 toggle mod as it stands. Services.jar and Android policy.jar both control this feature. I see that this *IS* available as a mod already on this forum but I am not certain that the creators realise that these modifications (mentioned here) actually do need to be performed.
Lidroid-res.apk within framework will have no rights to control the toggle on the systemUI cause it won't have permissions due to conflicting signature checking. note...toggles may appear, but they won't do anything when you touch the widget toggle, it will be non-responsive.
Thanks guys

Thats what i said we should just try copying over the whole system app folder and replacing it with our deodexed rom. Try doing that as the firstt step

System app is fine, but that isn't where the changes are that make Wanams ROM. You'd have your self a standard ROM otherwise. As in no difference. Or if you just copied the system/app folder ROM would boot but systemUI would force close. You would also have no reboot menu and no USB read from the phone. That would equal disasterous....cause as we all know we don't have SD mount in recovery do we?
Fancy doing an adb push on a phone that doesn't install USB connection files?
See I wouldn't be stupid enough to do that without having at least a clockwork recovery backup lol.
It's ok. for the android.policy.jar they are identical (well for XXALI5 they are anyway) to the i9300. So simple trade in there.
Only 4 more files to go and I will have you guys a port
Wanam still has not contacted me back yet though so I we need approval before anything.

---

Reset scrolling caches. In framework2.jar
This took a bit of work because my notepad++ kept crashing running compare. If you guys ever have this issue, right click the executable in program files go to properties and compatibility and then check the boxes for:
- disable visual themes
- disable desktop composition
- disable high dpi scaling.
Apply.
No more crashing. Windows 7 aero apparently doesn't like the compare dll?
Anyway not related. I am back on track. last jar file and then it should be ready to package up and it will be the same as Wanam ROM XXALI5

---

Got approval from Wanam. Just about to test flash now. Will upload it here if everything works out

---

Well, I had a few mishaps with my own device. Namely no root access and also lost hardware ID...meaning no Android Market. This all happened sometime during my lengthy list of modifications so I was not sure where. That mean flash back to stock and restore my data bit by bit until I was set up again. This take for EVER!
So yeah no real feedback from anyone in here so have decided to finish off my own ROM instead. XXALI9 (newer) and a heap more mods than stock Wanam. So far so good.
I can upload what work I did on getting Wanam's up and running (I have not flashed it yet) but will wait till someone actually wants before I go ahead and do that.
Thanks guys
