[Q] Need some guidance for developing a ROM - Galaxy S II Q&A, Help & Troubleshooting

Hi!
I currently own a GT-i9100T (Australian), but I have installed an i9100 ROM on it, so I guess they are the same models.
Firstly, I want to develop a ROM for GT-I9100 phones, but I need some guidance. I need a clean, booting kernel that will work, regardless of which custom ROM I will develop.
Secondly, I want to know if there is way to test my built ROM. Maybe dualboot? The last phone I had, I developed CM10 for it, and to test it I booted the ROM from an sdcard, by changing the locations of /system, /cache, /data in the boot image. So, is there a way to boot from the sdcard for this phone as well?
OK. So, to summarise it, I am asking for the following:
- A clean kernel that can be used to develop any ROM, and the ROM will boot.
- A dualbooting method to be able to test the new ROM. Possibly booting from sdcard.
I will look more deeply into the 'booting from sdcard' question myself, but I am still looking for guidance regarding it.
Thank You.

Wow! 58 views and no reply! Come on people; I expect more from you guys...

I develop my first rom from this guide only.
Good luck :thumbup:

Hahahahaha!
Thanks for your precious time, but that guide looks like it is for total noobs.
I am a senior member for a reason. I have developed a couple of ROMs before, but this is a different phone, so i am not familiar with this phone. This is why i was asking for some guidance.
I know how to developed, but I need to know the things in the original post.
Thanks.

@rqmok
Well I would think that you are building a AOSP based ROM? If so DorimanX Kernel lets you dual boot...... (Second ROM is run on the SDcard) You can use this kernel solely for testing.
Now for the kernel of the ROM, the cleanest kernel I can think of that powers CM AOSP AOKP is CM kernel? You can just compile from CM source and use it?

Thanks a bunch!!

Its not a custom firmware, but a tweaked kernel. Think of it as someone took the stock Archos OS and added/changed a bunch of the basic guts of it. Its based on the original system, but has improvements and changes Archos would never release.
It is possible to install on the internal memory. There is a thread dedicated to it in the development subforum.
I've used the overclock kernel but had some issues - namely the screen wouldn't turn back on after waking it from sleep. With overclocking each tablet is unique, so mine is probably unstable where others would work just fine. Honestly, once you have it running on the internal memory its slick enough you don't need to worry about overclocking at this stage.
Good luck.
Do you lose the warranty when you use the Urukdroid? It seems to me it is a stable system then, but I don't want to lose my warranty...
To install Uruk you need to install the SDE, which automatically voids the warranty.

Thanks mate for the reply, yeah i had the same trouble with oc 1280 kernel. however, Some one suggested that by callibrating the screen through repair menu at start up,it fixed that problem. another quick question, how would you go on installing it on internal memory, was'nt able to find thread regarding it. personally, i like oc kernel coz its pretty fast as compared to uruk..Thaks
Hi you all!
I've just installed the Uruk 0.6 for the frist time from a new full installation!
I've got a couple of little problem (my English is really horrible!... in reading too!!!!) now I'me a happy Uruk-user
I found HERE the full process to flash the Uruk on the internal Flash memory... but I'm too newbee with Linux bash, so I'll await a new Uruk relese with a full installer.
For the overclock kerel I found THIS tread written by ardatdat where you can find many overclock Kernel... it seems simple ti install! If I well understand, I will flash the only "zImage" by SDE... is it correct? the fix04 more exactly which seems fully function with Uruk... I'll try it!
And, finally, many tanks to $aur0n for this great work! really many tanks!
see you all!

[Q] Help w/ installing mod/Kernel on stock N1

Hi all,
First of all, apologies for a very newbie question.
I have a stock N1 with terrible battery life. I have stumbled intersectRaven's mod/Kernel at: http://forum.xda-developers.com/showthread.php?t=653598
I would like to ask how I can install this on my N1, is it just a matter of downloading the right file, renaming it to update.zip and then doing what I've done to update my phone as with official updates?
What do I need to pay attention to and is there a way to revert back to the original rom/Kernel if I'm having issues with this mod or if I want to sell my phone?
Thank you in advance!
You should have the clockworkmod on it. its the easiest way to install kernels. just have the kernel on your phone and click the "install rom from phone" button in the app and it should do the rest for you. I recommend backing up your phone. i never wipe when installing kernels always when doing roms though. Also a good idea is to look for the stock rom for your phone before doing anything to it so you can return it to factory. Goodluck!
Thanks merrick,
I will do some more research regarding the clockworkmod and see if that does the trick!

[Q] Question about step 1 of GSM flashing if already rooted/modified

1-SBF to stock base. Root your phone, unlock bootloader, install custom recovery and perform a nandroid backup of your stock rom!

So my question is all based on this, and after a lot of reading I found both answers but both were old so not sure which one to trust.
I am currently rooted, unlocked, running joker's CWM & Joker's CM10, and have a nandroid backup from back when I was running stock.
Is step one really to roll back to stock base, re-root my phone, re-unlock my bootloader, and make a new nandroid backup? Or are these instructions assuming we are not already rooted/unlocked?
Can I skip step one and just flash the new radio and then Joker's GSM CM10?
(Long time lurker, first time poster, 9 different phones hacked to bits and this is my first question ever, if this has been asked before no combination of GSM/Stock/SBF found it.)
Where can find definition and terminology
Can someone please give the link to the post/forum where we noobs can find definition and terminology on ROMS, kernl etc. ?

expertglossary.com/android/definitions/R (Banned from posting outside links.. Jebus it is hard being new, and all I could think lurking was I wish they had a method of making people talk *less*)
This might help a bit, ask if you want anything clarified. Their ROMS definition is a little not perfect, A Rom as it is normally used here is a zip file containing all the bits that makes an android install, A custom rom is a bundle of the kernel and android version, tweaks, themes, fixes, modifications, basically everything you use on a system as tailored by the ROM builders.

I was thinking more about " a guide to noobs" here in xdadevelopers forum ?
Where can I find it?
Definitely here is the best we have forum.xda-developers.com/showthread.php?t=1393519 then you follow all the myriad links based on what you are trying to do.
Not being sure what your goal is it is hard to be more specific.
Anyone have an answer for my earlier question though? My sim card arrives tomorrow.

Custom ROMs

Hallo!
I am ZTE Racer II user and i am looking for roms.
1 year of researching and no custom rom available on the net?!?
It was wierd,but that's it.
No roms.
So I need help with developing custom rom for this device,plz!!!
Thanks ahead!
You'll need to have some experience of linux and compiling from source, and knowledge on your phone's internal hardware. You might also need knowledge on the Android platform.
You'll also need to figure out how to get clockworkmod recovery on your phone
Good luck!
A little HELP?
Well ,I am not so good at that stuff ,but i want to have custom ROM.
That's why I ask for someone to make me a custom ROM.
Here is a link of the stock Rom I am using now.
www .4shared .com/zip/wNcQoJ9j/STOCK_ROM.html
I prefer MIUI custom ROM
And I installed this ROM via clockwork mod recovery and I'm using it right now.
Thank you ahead!
And I'm sorry the forum does not allow me to post the link because I'm new user!

[Q] How to start a new ROM for a GEN8 using the old one?

Hi,
I'm sure that's a dumb question, but I had to ask it.
I have a Gen8 tablet, and would like three things:
Backup the whole ROM in order to put it back later on
Use that ROM in order to build another one for the same device
Use that ROM (look&feel, apps and so on) to build another one for another device
I've seen that some firmwares (with root) are available for this tablet, and would like to understand how they were built.
Did the developers start from aosp + archos "modified" kernel, or did they start from the existing ROM (aos files from Archos)? Or even a mix of all that?
I installed the SDE yesterday, and have yet to make a complete backup.
Thanks.
Its hard to say where to start after asking these questions. You should read a lot before doing it. Roms based on Cyanogenmod like Buzcuit's one are easy to backup. If you base a new rom on the existing one you will get the bugs of the main rom (Bizcuit's for example) and the bugs of the new rom.
Thanks for your reply.
I don't know if I'll try a new ROM for such an old device, but do you know how these ROMs were made?
I've seen there how to build a new kernel for the tablet, but not a complete system (I often build android-x86, but never tried aosp).
This is rooted stock firmware. Its made by Archos. You should read a bit more about it. I am not a developer and I have pretty basic knowledge and I havent tried myself. Biz and the others can help you much more then me. But ya, u have to read pretty much to start.
Ok, thanks.
