bootloader is always original . samsung just updated the bootloader few weeks back, if you flash those roms with updated bootloader your bootloader gets updated automatically.

Sorry, for "original" i meant the kh3 bootloader... So even with custom roms I flash the new bootloder... I made this question because, if i remember well, i read that cooked roms don't flash bootloader...

yes, custom roms, doesn't install or update your bootloader, so if you're updating to ICS, you need an ICS bootloader.

Not on ics now but I'm pretty sure I've used it with the old bootloader. Don't think the ics bootloader is really required. I may be wrong.

Thanks to all, however, if you want to upgrade to a custom ics rom from a gb custom rom, you don't need to flash a bootloader... I flashed tons of ocs custom rom over gb custom rom with no problems...

Cool as in not overheating ???
a wipe and flash of stock rom will remove custom rom .
Root and custom roms void warranty and have a slight risk of bricking the phone .
But are usually recoverable .
You need to read the faqs and guides and understand the CM9 instuctions first .

to flash cynogen rom first u have 2 root ur phone please find the thread in original devlopment section regarding the same
u can reflash ur stock rom by dwnld the releavant .tar file adn flash the same thru odin
You can re-flash the stock rom, but just be sure to know which one is your stock rom. Go to settings, about phone and record the info there to be safe. Also back up your current rom using CWM.
There are always some risk in flashing a rom. Some people dont read instructions and cause problems on their phone, some people flash a rom not built for their phone (i9100 VS i9100G), etc.
Yeah i have rooted my device with cf-root. Thanks guys , i'll read some guides about cyanogenmod and flash it.
If your are currently on GB stock rom, Cyanogenmod developer recommends to install ICS bootloaded first,
You should be able to reflash your Stock ROM veriosn from ODIN, as well as custom roms from CWM...
What is bootload? o.o
My current firmware is ICS LP7

No they say to have below some specific ics boot loader, no mention of upgrading your gb boot loader, unless they changed it.
Plus I yet to had any issues with the latest ics or gb bootloaders..

I think he meant boot loader.
But since you already have ICS, you won't need it. Just take the latest CM9 nightly (or ROM based off it), and flash (you'll have to wipe cache data and dalvik too eventually). Make sure you make a full backup of your current stock ROM through CWM as well.

I refer this guide actually : http://forum.xda-developers.com/showpost.php?p=20841817&postcount=1
I dont know its outdated,
as others are sharing their experiance that you could flash CM9 straight away from your CWM since you are already on LP7 with ICS Bootloader.....
I don't get it... What is a bootloader?. I mean when i flashed with ICS LP7 i didn't put a file on bootloader. I just loaded the PDA .tar file and flashed it..
Soo that means that i have to reflash the stock rom with bootloader?

I dont know the ICS package you flashed had an ICS Bootloader already...
I just gave you the link for Original CM9 developers guide...
Just wait for others recommendation who have already flsahed CM9 from CWM....
Hmm thanks . But i have read in the guide that i can flash it with odin , do i still need the bootloader?
Hey
Currently have a rooted Xperia Mini Pro on 2.3 Gingerbread but it seems the official ICS 4.0 update won't be coming to my SI number so I have a few questions. I have decided to install a custom ICS ROM on my phone so would like it to be as fast as possible and very stable. So got a few questions for you.
My phone is rooted, do I flash Clockwork Mod onto it and then clear the data etc and flash the new ROM?
How do I unlock the bootloader and can I relock it later? Any easy method? And if I need to do this, do I do it before flashing the recovery?
I have apps installed on my SD Card. I know the ones installed on my phone will be wiped and I can re-install those few but will the large games and apks installed on my SD card be wiped too? Or will they still show up in the menu?
Do I flash the kernel that I'll need the same way as the ROM too?
And finally the most important question: which the quickest ICS ROM for the SK17i?
Thanks a lot in advance
There is 2 ways to unlock the bootloader, one official and one non official. I used the official http://unlockbootloader.sonymobile.com/ the other one you have to find on the forum. Both is possible to relock bootloader by flashing a ftf file thru flashtool.
Kernel is flashed thru flashtool and the rom thru cwm thats usually included in the kernel.
Apps on your SD card will not show on the new custom rom as the phone doesnt know that you have them installed so you will have to reinstall (or use titanium backup).
First of all I tried the official ICS on my SK17i and I didn't like it, it's alot slower than the GB with no super feauters that deserve it
I am now using the MiniCMSandwich Lite ROM. IT'S SOOO great and working very will. You can find it in a thread here.
Follow the instruction in the thread.
If u unlocked bootloader u can relock it but if u decided to unlock it follow the testpoint method not the official one because it's better.
Anyway .. Installing the official ICS or th ROM I told u don't need unlocking bootloader so don't unlock it.
If u want to root ur ICS u have to read that before Updating to ICS

Right firstly I decided to attempt to unlock my bootloader. It turns out for some reason I cannot unlock it (says not allowed in the menu). So suddenly a lot of the good ROMS are out of the question.
I have decided on the below ROM as Tayyar states that I don't need an unlocked bootloader. I know how to flash the ROM etc but how would I flash the Kernel? Or would it automatically flash with the ROM? I remember reading somewhere an unlocked bootloader is a MUST to flash the ICS Kernels hence my question
The official update has also not been made available for my phone and I doubt it will be so I will stick to my current version and flash the ROM now
About the apps on the SD Card, how should I go about it then? Should I get Titanium Backup and then do what with it? I have quite a few apps, it would be very annoying to need to re-install all of these.
Thanks a lot
Since your phone is rooted, try editing the region codes/CDA strings in /system/build.prop to a CDA code/SI number that has the ICS update. I did this myself when I reflashed my phone to get root on GB. I connected using Sony Update Service and was able to get stock ICS customized for my country using "CUSTOMIZED PH WORLD I 1254-1952"
What I changed was the CDA strings inside:
ro.product.name
ro.build.fingerprint
ro.semc.version.cust
You do not have to replace the whole value, just the XXXX-XXXX CDA string you already have there.
More info on these XDA threads:
[SOLVED] force update by editing build.prop, Also: [WIP] list of CDA strings!
Here's a list of available WT19 CDA codes for different countries/regions.
Credits go to original posters.
Titanium Backup is always a great app to use. Only caveat is, you might want to manually restore apps instead of doing a batch restore; some of them might not work with the jump from GB to ICS. Also it would cause a lot of trouble if you try to restore Contacts Storage from a GB ROM to an ICS ROM. Just stating my personal experience

Kernels can only be flashed with an unlocked bootloader. Kernels get only flashed via fastboot mode. A cwm flash is not possible at the moment.
You can flash custom roms via cwm. Your bootloader is locked, so you have to look that your choosen rom is compatible with your bootloader.

I think you could unlock it via the testpoint method, if it says it's not unlockable.

My friend, ICS for Xperia mini/minipro sucks.. Its was slow compared to GB. I've tried all the tweaks, hack and other bullshits.. now i am back to GB. and i am very happy i did. But if you really want ICS, then Minicms/CM9 is the best choice.

Hello,
a friend has a rooted S3 (Carrier is Austria-A1, but not sure if it is branded) and after using a Debloat-tool on Jellybean (stock) it ran into bootloop.
He can still enter Odin and CWM on the phone, but unfortunately he has no Nandroidbackup. :silly:
We have found the Stockfirmware here:
http://www.handy-faq.de/forum/galax...galaxy_s3_jelly_bean_4_1_x_firmware_dach.html
How can he recover/flash his S3 with this stock JB from the above webpage to make it work again?
He also has no SD-Card in his phone so he can´t copy any software to it, but i have an old 1GB microsd-card which can be used if necessary.(no sdhc)
His PC is running Win7-x64.
Sorry for noob-question, but i have a Sony and don´t know anything about Samsung devices.
thanks
get the rom straight from samfirmware.com and flash it throug Odin
All data should remain intact.

Ok then we will download the firmware from your link if you recommend this.
I will visit him in 30 minutes and will report if it works.
Thanks for reply, mate. :good:
Thanks d4fseeker,
have downloaded the unbranded firmware from your link and flashed with Odin.
All contacts and apps still there, and phone works fine. :good:
Just he has to root again.
one last question. If he want to flash custom ROMs is there still need to unlock bootloader?
i ask because i wrote before, that i have a Sony, and there you can flash ROMs just with root&cwm and locked bootloader;
only some ROMs (not stockbased) wich need a own kernel or flash custom kernel needs to unlock bootloader.
thanks again, mate. !

S3 bootloaders all come unlocked with the exception of the US Verizon variant.
Oh, so that means he can flash kernel and rom what he want, cause he has root.
Cool. But strange so different... a other friend with HTC needs unlocked bootloader for root, my Sony i can root without unlock Bl...
I will tell my friend this and for more questions he should register himself here on XDA.
Thank you ! :good:
Hey guys I rooted this phone almost a year ago and installed a custom rom. I remember the procedure being very different from other phones I have done and very complicated. At the moment I am still "S-on" and running Android Revolution HD 1.1.0 (android 2.3.4)
My goal is to install the newest version of Android Revolution ( looking for a very stable rom, so I'm open to suggestions)
The thread mentions extra steps if you are coming from a non-ics rom.
Also Im considering the Energy rom. (this one does not specify any extra complicated steps)
In the current state that I'm in should I run the all in one s-off tool? do I even need that for these roms? what recovery should I flash? (Im currently on a CW based recovery)
Thanks in advance for all the help.
you should first flash back to stock.... then update to ICS... after that you should once again unlock your bootloader and flash 4ext recovery this time.. but you id really suggest updating to ICS before trying to flash any ICS roms..., specially since your still "S-ON"

To my understanding, flashing back to stock requires the stock recovery and a stock image.
I found the stock image here http://forum.xda-developers.com/wiki/HTC_Amaze_4G/ROMs#Stock_ROMs
but can somebody help me find a stock recovery?
