[Galaxy S II General] Gigalisk:
PLEASE READ THIS!! Hopefully i'm not too late....

STOP WHAT YOU ARE DOING IF YOU HAVE A SHW-M250* FAMILY SAMSUNG GALAXY S2!!

Now that that has been done...here is the hardship i have figured out in the past week, and these are purely FACTS from nightly hours of beating my head in with a softbricked Korean SGS2.

If you have a M250* Family SGS2, DO NOT USE SAMSUNG KIES TO UPGRADE TO ICS.

You may fry your modem..

USIM/NFC/TMoney capability may be forked (see what i did there)

Airplane Mode may stick sometimes

If it doesn't fry your modem, your modem will drop signal for at least 55-60% of your battery life

Your battery life will be FAILSAUCE

Currently, there is no Aftermarket Kernel Suitable for the M250K by itself.

You have to reflash to GT-i9100, which, if you have been reading, provides more problems than satisfactory results.

You ARE able to root your phone using CWM and installing the CWM Superuser+Busybox Zip, but it will block connection with KIES.

YOU MUST WAIT FOR A SUITABLE KERNEL SPECIFICALLY MADE FOR THE M250* FAMILY, or risk the problems associated with reflashing to GT-i9100

ODIN, is your friend.

Don't be scared to go into DL mode and use odin to install your updates. It works for Legit, Factory-written updates as well as custom roms.

Odin will test the ability of your phone to Send/recv data. If you do not get the yellow (ADDED) signal in Odin, you may have a hardbricked phone. Follow directions about how to enter download mode before you toy around with Odin, or it will slap you with its mighty beard.

BECAUSE FOTA IS GUARANTEED TO SEND YOU THE FIRMWARE ASSOCIATED WITH YOUR PHONE, IF THERE IS NOT AN UPDATE FOR YOUR M250* THROUGH FOTA, THEN IT DOES NOT EXIST...YET. WAIT FOR IT...

I noticed this when i flashedback to Gingerbread 2.3.6. and registered for FOTA, it brought me to Build GGB.FB22. When i connected to KIES, it wanted me to go to ICS. Now i remember, when GGB.FB22 came out i connected my phone to KIES once, and it asked me if i wanted to go to GGB, and i declined, opting to do FOTA. The kicker is that now, ICS is only offered on KIES and not through FOTA, meaning there is not a proper M250* version available; the version on KIES must have been retrofitted to latch on to the chip without totally bricking it. They didn't think we would notice through the smoothness of the ICS.

Bottom Line: Rooting/Deving/Hacking Droid phones is awesome, but it has its challenges; one of the biggest of all is that some versions, such as the M250* Family indigenous to South Korea, are very overlooked due to everyone getting the international version. Only in a select few cases have i seen a phone flashed to i9100 where it has been successful with a less than 5% error rate. My suggestion, and because i have one of these phones and i have gone through the heartache of finally getting ICS just to go back to GGB, is to wait for m250* Roms and kernels to come out rather than the i9100, just because of the extra NFC internals, USIM interop, and tv tuner.

I will include this in a guide i'm about to write concerning rolling back versions for M250* phones, and Rooting. There isnt enough, and i'm not going to bother devs to write it. Since i already read their work, i will just compile a guide for everyone. Coming soon guys. Don't worry, i wont leave yall in the dark.:cool:
