Should be safe flashing to a stock i9100 ics rom though you need to convert the phone first from m250k to i9100.

More info of Brickbug;whether it's safe to flash or not:http://xdaforums.com/showthread.php?t=1693704

Instructions of how to convert phone below/reposted from couple of previous pages back.
[Galaxy S II General] yorville:
Hmm so I can't convert to i9100 ICS ROM then? nor downgrade to GB? I asked google if there were any M250K stock GB ROM but still no luck.

So ticking the repartition in ODIN isn't safe right? KIES sucks
[Galaxy S II General] HadenVR:
You can go convert the phone in odin, just it isn't suggested to wipe in recovery like cwm which may trigger the brick.

Whether the re-partition is ticked or not in odin, it's not going to trigger the brick so it should be safe.

Congrats on your first post on XDA.

In case you don't know, please PLEASE make sure next time to search the thread of your questions before posting them which can be found on the top page of the thread as someone else may have most likely asked then posted the same questions you may have had and do simply read couple of posts back from the most recent post as the answer to your question may be there already.

I highly suggest to read the FAQs though if you don't want to read it(as most new members don't bother doing so) or simply just want to skim through the most important rules, just watch this short informative 2 min clip http://www.youtube.com/watch?v=JmvCpR45LKA as this will help lower/answer the most common questions/problems you may have had during your search in XDA. Now onto your question.

The phone will remain unlocked once it is unlocked and will not re-lock itself during or after the process of flashing roms/kernels/radios/factory resetting the phone.

As for the instructions on how to root the phone, it's 5 posts above yours.

Happy searching.

Hi,

I am new to this forum and new to android also.this is my first post. I have a Samsung SHW M250K mobile. I have updated it to ICS 4.0.4 using samsung kies earlier. I need to convert my mobile to i9100 and try some custom roms If possible... I saw in earlier posts that [kaizer216] has given a great tutorial of doing it. but since I am new, I am confused of finding an ICS rom for my device from samfirmware (is it a i9100 rom or SHW M250K rom should I download ?// sorry for the stupid question. I am too new to android). here are my specs shown in "about phone" section.

You can root your phone by flashing Siyah kernal using pc odin.It will install root and CWM.Now your phone is i9100 nt m250k anymore.

Download this and flash pda in odin

yes you can use new leak of jb after conversion to i9100.After that Just follow same instructions as i9100

You can install siyah kernal its best balance for performance and battery.It will install root and CWM.Then you can install custom roms.I will suggest Wanamlite or Sensation ROM 4.

Flashing Leaked Jelly Bean 4.1.2

From what I have been read in this forum, it is possible to flash the leaked JB 4.1.2 in our phone (m250K).

Just want to confirm, please, as i do not want to have a bricked phone.

1. When flashing (via ODIN?), i have to include pit file (16 or 32 depending on the size of my s2), right?

2. I can flashed back to ics or any other custom rom anytime I want right via odin too?

3. I cannot flash leaked JB 4.1.2 or any custom/odexed rom of leaked jb 4.1.2 (such as wanamlite, omega and neatrom) via CWM since they don't usually have the pit file (if yes is the answer in number 1)?

i have tried to flash it via odin without pit files but it failed twice. tried using cwm (flashing wanamlite, omega and neatrom) but it stuck in samsung logo (though no bootloop). so per this thread suggest, pit file might be the solution.

someone please with good heart. Thanks!

you can install JB leaked rom on your phone. you need a i9100 PIT file for that..to install custom roms, you have to convert your phone to i9100..look page 104. there is a tutorial how to do it. you can also flash JB rom and root it and install custom roms. there are experts here. they will help.what I did is, I converted my phone to i9100 using android 4.0.3 rom ( JB wasn't there at that time). but now I have JB leaked rom. you can convert your phone to i9100 using JB rom directly as I think..after converting you can play with your phone because It is a i9100 :good:

Device memory full - Samsung Galaxy S2

I have an SHW-M250K with official ROM (unrooted) and my internal device memory is running low.

Only about 255 MB is remaining free out of total 1.97 GB.

This causes error message "Insufficient storage available" while downloading / updating larger apps.

There aren't many apps installed to consume so much space (and moved many to SD card also).

Tried doing a factory reset yet the problem comes back.

i am running on 2.3.4 rom .. i also found out that it doesnt show the IMEI and SN in the Settings/About Phone/Status

the phone have its internal storage consume by pictures and videos of the 1st owner of the phone.. i can delete it manually using file manager or in the pc via usb storage, but after a reboot, it comes back again and all the files and applications i've downloaded in the phone will be gone.. i can't overwrite the system and internal storage, .. i already tried formatting the internal storage in my laptop, it succeed and no files are shown and i the capacity is 11gb+ something again.. but then after i eject my phone and reboot, it goes back to the way it is again.. its kind of frustrating really.. now the owner won't reply to my text and messages.. i can't live without a fix phone..

yes you can. you can also use the PIT file attached in page 104. the thing is, you need a i9100 PIT file. that's it. If you already converted your phone, you don't need a PIT file to flash JB leaked rom. good luck with Flashing.

Conversion possibility - is it possible without bricking???

Hi,

I'm from Bangalore and recently got a SHW-M250S from Korea. It already has 4.0.4 SKT Stock (Korean) firmware updated through Kies.

I want to flash the following Indian firmware on to it and convert it to i9100 to get rid of the SMS limits and some unwanted Korean apps / stuff. I am ok to live without FM radio! :(

I have also downloaded the i9100 PIT file. Is it a possibility? I read about the SuperBrick bug while flashing on 4.0.4 and other issues after converting to i9100 such as slow accelerometer and compass issues. BTW, I am a heavy user of GPS as well! :(

The following are the details about the phone:

From settings - about phone

Version (Information displayed after pressing : *#1234#)

The MOVINAND : NONE is another worrisome factor for me.

Do I need to just flash the above firmware with Odin with repartition selected with the I9100 pit file? Will the phone work fine after flashing?

Please guide me in providing some advice and steps to proceed further.

Should I check for issues using Chainfire's app or any other steps to be performed?

Please! What should I do?

Check if there is any possibility of recovering the IMEI. I am also looking at options of writing a noted IMEI to the phone.

By any chance do you have the IMEI noted down in any screen shots, notes etc? Also, check the battery slot. It should have the IMEI printed there.

For restoring, you might have to flash any rootable firmware and try with GSII_Repair application from Android market after rooting. Install BusyBox and GSII_Repair and follow the steps in GSII_Repair application. I have read it somewhere that it can restore the IMEI, but I have not done that.

You have try it out and see if it works. Thanks.

Here are two sites you can find online.. Both reputable and i have personally used.

Hxxp://www.gmarket.co.kr and auction.co.kr .. The latter is an ebay company or affiliate. And gmarket has an english option..

[Galaxy S II General] andyhk888:
For the Roaming Auto Dial option, I think that T-service app that Wapu posted about sounds promising. Since the i9100 is basically almost the same hardware, I guess we could give it a try it if someone with the T-service app could use Astro file manager or something similar that can save installed apps as an apk backup. To fix that sms problem you need an iphone 3gs to add your phone number to the sim card. I fixed the sms sender problem this way.
