[Q] custom ROM for gt-s5830i

I have bought a galaxy ace and unfortunately it is gt-s5830i which hasn't got any custom roms till now as far as I know isn't there anything that be done to overclock this phone over 832mhz. ickyyy wrote that we can use the roms of galaxy y but it would have some bugs such as camera would not work. ickyyy if you are reading then please help me I can bare some bugs but I am mainly excited to overclock my phone. In one of your posts I found the clockmodrecovery and have backed up my phone please can you suggest me that whether should I use a ROM of galaxy y and if the bugs are too much for me can I restore my phone (as it is my first Android and I have bought it 3 Weeks before and haven't used Odin etc).
Also it would be a great help if you tell me or just give a link to the full and the easiest easiest way of flashing.
My advice is don't risk to flash ROM's for galaxy Y.It has the same hardware,however it's not 100% sure that it won't kill your phone.The display resolution is different.It may be posible that you would be able to flash and run it but it has no point.For overclocking you need a custom kernel which.Flashing a kernel for a different device may be very dangerous as it can kill your phone with no chance of reviving it.Just wait some time and there will be custom roms,kernel and everything for s5830i and you'll be able to overclock it.Many people are currently trying to port some ROMs and developing kernels but there are no good developers for this phone yet so it's very hard and slow...don't rush it!Use the stock rom.Samsung must release a new update to optimize applications and the videocore IV so it should give better FPS on games and etc...
hi ickyyy .
where are DEVs . why they dont work on s5830i ?
there are a lot of people waiting for a custom rom for 5830i !!!!
sorry for my english .

Developing

My phone, Gt-S7500L (galaxy ace plus) isn't so famous among the Android owners, so there are many custom roms. We dont have Cyanogemmod, and its is a sad thing, but im actually trying to port it from the galaxy ace throught the android kitchen. I m afraid of bricking my phone, so my question is if i use the STOCK kernel in the custom ROM that i'm porting, is there any chance of HARD brick(softbrick isnt a real problem,i backuped the OS)? I know! Custom rom without custom kernel may dont make sense, beu we, ace plus owners, are desperate.
Thank u :good:

bricked= bootloader corrupted if you don't touch bootloader nothing happens
maybe you think about a hardware failure ..this is possible when porting a rom
to port a rom is not about copy/paste files from somewhere if you see kitchen has "experimental support" for porting it can help you to "put things together" I mean to root that rom and add some features then pack in a flashable .zip format but you need a rom for that ! kitchen can help you to port in the case you get Cyanogenmod sources for a device that is almost the same as hardware specs with yours

[Root] Samsung galaxy beam I8530

Hey guys im gunna try to keep it short. happen to be browsing thru android Q&A and saw a thread of people trying to get root on a phone so i figured id help em out
luckily sammobile had the stock tar up for it so it was just a matter of grabbing that, unpacking the initramfs. then grabbing kernel source and compiling a rooting kernel.
Kernel
Odin
Drivers
Credits:
Sammobile for having the tar
hallihallo87 for testing my kernel
Like my work? you could always help pay for my daughters college ​
Instructions​
Download the 3 files above
extract odin-1.85.zip
install the drivers
click on pda and select the rooted kernel tar
put your phone into download mode
Download mode is power + volume down + home
once you are in download mode connect via usb
you should see a yellow com pop up in the far left box
click start
congrats
sorry for the vague instructions guys they will improve as time goes on as people who actually have the phone chip in
Works great. Thanks!
Downloadmode is power + volume down + home
Sent from my Sensational phone
Looks great! I'm about to try.Thanks
Works great on my beam. Thanks a lot!!
Rooting successful!
Rooting via Odin with this kernel really ROOT my Galaxy Beam i8530. Kudos to ShabbyPenguin! :good:
Has anyone tried the SIXAXIS tool for PS3 Controllers? it doesn't seem work for me unfortunately.
I've read that the rom probably doesn't have all required bluetooth protocols in order to make it work and that a custom rom like Cyanogen will be required.
Would it be possible to take the Bluetooth Stack from a Cyanogen mod and put it in the Galaxy Beam ROM? Maybe from the Samsung Galaxy S2 Cyanogen Mod as the phone is mostly the same minus the projector.
I doubt there will ever be a Cyanogen Mod project for the Galaxy Beam unfortunately.
glad everyone is having good success with this

We will need to port ClockwordMod, so the cfw will be easier, but i don´t know how to make a dump. I only have a dump from Odin Mobile.
We need to look at "Samsung I9070 Galaxy S Advance" as it is the same phone (without projector) all the specs is the same, not Galaxy S II.
But i can see if i can get it to work tomorrow. I have a Ps3 (3.55 CFW)

I had a look at the Galaxy S Advance and there are no Ice Cream Sandwich releases for it.
I'm also still looking for a way to add usb host mode.
@shabbypenguin Kudos to you !! , you've done awesome. the root is working fine and only thing all us can hope is CWM recovery if you could help us in that it would be amazing, though i am willing to help in development (like beta testing / dumps). hopefully we shall have CWM soon and make use of this awesome phone.
regards,
richie
hope soon have custom roms for this projector phone
hi there,
successfully rooted my beam but ever since the focus for the projector doesn't work anymore.
anyone else with this problem or my phone have a hardware problem ?
how can I go back to official kernel please ?
thanks
update:
I installed the latest firmware LH3 from samfirmware.
the focus still didn't work after that so I shook the phone a little bit and it came back to life so I guess it wasn't a software problem.
I'll keep you informed if further development arouse
TWRP?
So.... the guys over at a thread for hacking the i9070 (galaxy s advance):
http://forum.xda-developers.com/showthread.php?t=1640757
were successfull at embedding TWRP (recovery) into their kernel. Since this phone is very similar to the i8530, i was wondering how risky it would be to flash that kernel on the i8530. If anybody has any knowlege about this, please enlighten me so that I can have a better understanding about the risk i would be taking if i flash my i8530 with the hacked kernel for the i9070. (e.g.. will the difference in screen technology cause any problems? i8530=tft, i9070=super amoled.
I8530XXLH3 Root ?
hey shabby ,
+1 on the request to root I8530XXLH3, i am waiting to flash that build , but hesitant to do so untill root is there......
P.S. : are you familiar with recovery too ? cause we really need custom recovery and at the moment you are the only dev we can look up-to
best regards,
richie

i cant promise anything with cwm, but i suppose i can try but ill need testers. as for rooting new firmwares this kernel should work on all versions of GB, until samsung updates kernel source i cant build a newer kernel.
since i dotn have the phone im not going to bother checking on the device files everyday so if someone could PM when new kernel source comes out ill update my kernel

i have read in the forum somewhere that i9070 guys have successfully integrated TWRP (Team Win recovery project ) recovery in their phones, so probably we can have that one because apart from screen and projector all is same, is it worth the mention ?

richie
here is a test cwm build i made, please lemme know how/if it works.
if it boots into cwm then dont flash anything, do a backup and let me know the sizes etc of the backup files. would hate for you to brick your phone cuz you wanted to restore a backup etc
www.shabbypenguin.com/OUDstuff/Samsung/Random/Beam/Beam-I8530-Test-CWM.tar
as far as future firmwares are concerned, so long as its GB this rooted kernel should work. when you get an update to ICS i will absolutly have to make a new one for yall. but i cant do so until http://awesomescreenshot.com/0dch109f6 gets updated :/

[Q] Question about custom ROM developing (Help is needed)

Hello!
I am an AndroNoob and haven't done much. I just have rooted my phone, used odin twice and tried to get cyanogenmod. I have got the Samsung Galaxy Xcover (GT-S5690) and i really would like to have android 4.0+ on it or even run 4.0+ apps on it. After about 5 days of searching a custom ROM that works good and is android 4.0+, i decided to make my own one. I just want to ask you, is it possible to use android kitchen or something to just get the original rom from sammobile or some other place and just make it be ics/jb or get likes 4.0+ firmware for galaxy ace or something and make it work with my xcover? And if so, how easy will it be (Should i even start using/wasting my time on it)? And last if possible i would like to have the samsung style android
And i would be so happy if i can get it done, get my xcover run ics/jb!
Thanks for any help and sorry for my bad english.

[Completed] [q] porting kernels of devices to other devices

Story how i got that idea
(Skip this if u dont give a single **** about other people)
Can anyone please help me
I have a Galaxy S3 with a half-way-broken Screen. The reason why i say half-way is because the display actually works butt has very very low brightness so i am not able to see anything on my screen when i go outside or go into a room that is bright. Before i got this S3 i had many other phones like Omnia 2,Galaxy s2,Galaxy Note, and so on and i remembered a feature from siyah kernel on my Galaxy S2 wich allowed u the set a GAMMA SHIFT up to 50+. It was goddamn bright and i also knew that the siyah kernel is also awiable for the S3. After flashing it i was very dissapointed because exactly this feature was not there anymore. I flashed al the older versions of siyah kernel i found but non of them had gamma shift. Then i searched for another Kernel that could have this feature but i was not lucky at all. I quit messing around with my phone and used it as it is even it was a real pain in the ass. Some days later one of my friends who is also a person that has very good knowledge about android, ROMs, Kernels,.... He told me about that he has succesfully flashed a Galaxy Note 2 ROM to an Galaxy Note by only changing the files in the meta-inf folder from GT-N7100 to GT-N7000. When i heard about this i have tried to do the same with the siyah kernel from s2 to convert into a s3 kernel with the features from the s2 kernel that was missing. So long i had no luck by converting it. i have also looked up to threads in there people show how to convert ROMs from phones to ROMs for another phones.
THE REAL QUESTION!!!!
Is it possible to convert a phones kernel to another phone?
If yes, how do i do it?
Which programms do i need?
Can anyone please help me with that?
