[Galaxy S II General] PJK2011:
I am the happy owner of a new (to me) M250S. I am very grateful for all the knowledge shared on this thread that made it possible for me to convert to i9100 and flash to CM10.1 so my phone is now set up the same as the i9000 it is replacing.

The only thing that is not clear after reading the thread is the issue of exactly what bands are supported on this phone. Back on page 16 it was stated that this is a single band (2100) 3G phone with additional support for GSM (2G I presume) 900/1800/1900.

But this does not appear to be what the phone says about itself. Using the band select menu, I get this menu:

GSM/CDMA auto (PRL)

EvDo only

LTE/CDMA/EvDo

LTE/GSM/WCDMA

LTE only

LTE/WCDMA

Unknown

Automatic

EURO Band

USA Band

JAPAN Band

AUS Band

AUS2 Band

This is somewhat confusing because it does not specifically say what frequencies are supported here, but it does seem to suggest that there is more than a single 2100 band. The comment above about GSM frequencies is confusing to me too because I know GSM can carry both 2G and 3G signals. Also, I bought this phone on ebay, and ebay's pre-filled specifications (for whatever they are worth) shows considerably more that is equally baffling as to what it means:

Cellular Band:	GSM 850/900/1800/1900 (Quadband) HSDPA 850/900/1900/2100, GSM 1800, UMTS, GSM 1900, UMTS 2100, GSM 900, GPRS, HSUPA, EDGE

On page 18, a very significant post was made by user srr118 because he linked us to the actual Samsung.com page on these phones where there is a downloadable user manual with the actual specifications. This is what it says about the bands:

WCDMA

r 송신(TX): 1922.8 ~ 1977.2 MHz

r 수신(RX): 2112.8 ~ 2167.2 MHz

GSM

r 송신(TX): 880.20 ~ 914.80 MHz

r 수신(RX): 925.20 ~ 959.80 MHz

DCS

r 송신(TX): 1710.20 ~ 1784.80 MHz

r 수신(RX): 1805.20 ~ 1879.80 MHz

US PCS

r 송신(TX): 1850.20 ~ 1909.80 MHz

r 수신(RX): 1930.20 ~ 1989.80 MHz

WCDMA: ±200 Hz 이내

GSM: ±90 Hz 이내

DCS, US PCS: ±180 Hz 이내

These numbers are equally cryptic to me because I don't thoroughly understand what frequencies are used for what. I would appreciate it very much if someone could come in and explain in plain English what this tells us about what frequencies are for GSM telephony, which frequencies are for 2G and which frequencies are for 3G. I'm also wondering if there is 3G+ support because the phone menu lists "LTE".

Thanks!

Been leaning towards the Korean versions of S2 (since local versions are a bit expensive in my place).

Some of the tutorials I've read here are a bit old, only featuring Siyah kernel as a probable kernel to convert.

Are there any other recent i9100 kernels I can pay attention to which are supported by M250X S2s? Or am I missing something?

Appropriate Replacement Battery for SHW-M250K

I have a Galaxy S2 bought in Korea and am looking for an appropriate replacement battery for my model:

SHW-M250K

I didn't know there were so many variations of the S2 and the hits on Amazon specify different models in the states but don't specify if its compatible with my model from Korea. Ideally this would be a high capacity, reliable battery. There seems to be a lot of hoopla regarding NFC. Ideally the battery will allow my phone to function fully, but the NFC capability is not a priority. Compatibility and reliability followed by longevity, would take precedence over NFC capability.

I searched this thread but couldn't find any recommendations for specific batteries. If someone can link me to one that's compatible with mine I'd be grateful. Thanks ahead of time.

Update to JellyBean?

I have an M250S and I can't seem to update it to stock Korean Jellybean using Kies.

I can't convert it to an I9100 since my mobile network stops working for some reason. It says "Emergency calls only"

and I'd like to install an official Korean Jellybean rom on this. When I use Kies, some stuff in Korean pops up and I click "Next" then another button. I have no clue what's written. Any help here?

[Galaxy S II General] Kashif.Ali:
Convert shw-m250k into I9100

1) Download a i9100 Pit file and a i9100 ROM with a rooted kernal, then flash it via ODIN..

2) Flash the latest CWM Recovery (otherwise get a ROM that has CWM already in the step above)

3) Download Cyanogenmod 10.1 from the official site

4) Flash it via CWM Recovery

5) Now you should be running android 4.2.2 with no problems.

my question: can i use this one rom i9100 XWLSD 4.1.2 Jelly Bean rom?

and

if i am using this rom why should i need to download cyangenmod 10.1.

or please give me a link of "rom with a rooted kenal"

Speaker replacement for SHW M250K

Dear Experts,

I am having SHW M250K. Somehow the liquied chocolate entered through the loud speaker into my phone and turned solid inside. Now loud speaker volume is reduced a lot.

I tried opening the phone however the speaker is all closed entity and glued. I referred some videos on youtube. Most of them are for standard Galaxy S2 however haven't found any video for replacing the loudspeaker of SHW 250 series (korean made).

Can you please help in opening the loud speaker of my SHW M250k.

Thank you.

Is there something wrong with me?

Overall goal: I want to use my Korean-bought M250S on a virgin mobile network in Canada.

1. Tried to flash Siyah, using ODIN, got a fail result.

2. Successfully did what this guy said (turned my M250S into an I1900) http://xdaforums.com/showthread.php?t=2424857

3. Tried to flash Siyah again, failed again.

5. Managed to flash a British stock rom. Still was not getting a signal.

6. Tried to flash CF closest to the kernal from the British stock rom. Got black screen.

WHAT DO?

I can get into download mode still.

I've spent hours reading through responses in this thread. I'd really appreciate some specific feedback. Am I missing a step?

Update: Succeeded in flashing Siyah. WAS TRYING TO FLASH AN S3 VERSION THIS WHOLE TIME. Found v 5.0.1 and successfully flashed using odin.

Still to do: get rid of "orange" rom (?) from above link and connect to phone network. Still using the phone as an I9100.

Update 2: success with this combo: Turned my M250s into i9100 -> flashed Siyah Kernal with odin -> Internal SD installed Cyanogenmod version 10.1.3 ROM and relevant google apps package from cm website -> do happy dance.

BUT, phone cannot be used on virgin network (Canada) as far as I can tell. Please correct me if I'm wrong.

I went through the threads and found a keystr ON set thing. I was able to do it but still no luck. I create a keystr file in /efs/imei folder,kept the value as ON, set the permission as rwx-rwx-rwx, reboot. Still the problems persist. Any solution do help.

Is that applicable to shw m250s...nd will it resolve my issue?
[Galaxy S II General] axel-529:
Aww! That's bad news... I think the only way you can fix that is by restoring imei back up.. Do you have nandroid backup, try restoring it though i doubt it can be fix by doing so.

Or, try looking into the net the generic imei backup for galaxy s2 and use that in restoring your phone.

Does this mean it's impossible to get the SHW-M250L working in US? My gf just brought one back after using it in Seoul and it seems to be impossible. I can't find an imei at all.
[Galaxy S II General] Sticks02:
I don't follow the S2 development anymore (Using a lovely International S4 :D) but the M250L uses Korea-specific CDMA bands which aren't supported in the USA. You're SOL, Ebay it. :p

they even switched the imei to a i9100 one!

i started seeking this forum for information about this,

tried switching firmwares and kernels, and even stock version 4.1.2, and of course a lot of gps problems guide in here but i couldnt get it to work.

my question is how can i know if the gps problem is hardware\software problem?

is there a chance that going back to SHW M250S firmware would solve this issue?

and of course, if i would need to change the gps part, are the i9100 gps part is the same as the korean version??

plsss helpppp meee
[Galaxy S II General] mrchrisrueda:
Bro authentic shw m250s is with antenna while local version or international version doesn't have. I recommend slim bean ROM by fusionjack. It will solve everything.
[Galaxy S II General] humy456:
try this out to revert your galaxy s2 to SHW-M250S back. http://ilmubarokah.wordpress.com/20...-korean-version-shw-m250x-to-jellybean-4-1-2/
[Galaxy S II General] mrchrisrueda:
Dont revert back as reverting back will revert back to Korean version, Korean version has a lot of limitation but if you are in Korea its okay but if not, I suggest not to
[Galaxy S II General] saniel:
This is my device...what is that, not a converted shw m250?
[Galaxy S II General] mrchrisrueda:
I cannot see the image, just tell me if your device has anthena at the right top side. If yes then its a converted unit if doesn't have then its a local unit. Another thing to check is the label inside the unit, remove the battery and see if its Korean text if not then its not
[Galaxy S II General] saniel:
There is no antenna, basicly the photo shows 5 diffrent places on the board writen shw-m250s

And the phone formation is not as the international gs2,the battery is flipped like the m250s and the sd slot is under the sim, thuo there is a label says i9100, i am preatty sure this is a fake label put there in order to sale this device after converted as international instead of a korean version.

This is the photo link maybe this would work:

There is no link please send it again
[Galaxy S II General] saniel:
I was thinking about reverting back to korean in order to check if the gps problem is hardware or firmware trying to isolate the problem, afterwards hopefully if the gps would work in korean version i would try and find a working i9100 version. It is mainly just to check my gps. I have no other ideas...like i said i tryed flashing and wipe to stock rom 4.1.2 for i9100 downloaded from sammobile and it failed to fix my gps. :/

Download antutu benchmark, it can tell u if your device is authentic or not
[Galaxy S II General] saniel:
Ok, iv'e downloaded the benchmark and after the test it said i9100. Is there another check or this mean that he is not fake?
[Galaxy S II General] mrchrisrueda:
What device are you using right now? Coz your signature says i9305, its lte s3?
[Galaxy S II General] mrchrisrueda:
See image, that is the test I've done my authentic shw-m250s converted to i9100, if antutu says its gt i9100 like what in the image then its authentic, if not then its fake
[Galaxy S II General] saniel:
To send the msgs im using my very much original i9305 but im asking about my moms not so much original i9100/shw-m250s...LOL.
[Galaxy S II General] mrchrisrueda:
See image, antutu can detect your GPS then there is a problem with firware , if not then hardware problem
[Galaxy S II General] saniel:
Yep. This is what it says. So now what? How can i get the gps work for me?

Try to revert it to shw again and see if the gps would work? Or maybe try another ver. Of clean 4.1.2?...its so frustrating...
[Galaxy S II General] mrchrisrueda:
Please confirm if antutu can detect your GPS?
[Galaxy S II General] humy456:
i have same case here, my shw-m250 imei is recognized as gt-i9100, and i feel my gps works better with original firmware, give it a try, perhaps he will find whether its better or not for him. :highfive:
[Galaxy S II General] saniel:
yes ! it says SUPPORT GPS, SUPPORT A-GPS.
[Galaxy S II General] mrchrisrueda:
Then its not hardware problem... Maybe you want to upgrade your to slim bean..

Hi mrchrisrueda,

Would this same procedure with the same files work for my daughters shw-m250k as I got it stuck on update screen and can't access recovery mode either? I live in the UK so would it be better for me to use UK firmware, apologies for newbie questions?

Thanks
[Galaxy S II General] mrchrisrueda:
Its different. I'll post the links in a while
[Galaxy S II General] dkennedy1001:
You're a saviour thank you mrchrisrueda and I will try this tonight when I go home from work as this update screen is very very annoying!

To be honest I'm normally quite techy (I work in IT) but it really is confusing all these different firmwares and wondering do I need a korean firmware or uk one or when flashing with Odin do I load PIT, pda, modem and csc or can you load one without the others! Maybe a uk or general firmware would be best.

So many variables so tips on this would great too as i guess you are an expert...

Many many thanks

Further info if needed that i took down before killing it...

android 4.0.4 kernel 3.0.15-1042229

[Galaxy S II General] mrchrisrueda:
I believe UK is also GT-i9100 so heres the stock official firmware for UK, download here

extract the file and use the odin included in the package.

open your phone to download mode (Home + Volume Down + Power), open odin as admin the click pda and choose .tar.md5 the start.

Hope this help... when your done, dont forget to hit thanks
[Galaxy S II General] dkennedy1001:
Thanks mrchrisrueda, I will try this tonight and I will hit thanks :)

Can you explain do I tick partition etc in Odin or what settings do I use when importing this file please and why no PIT file or CSC (for my own understanding)?

Also last night I did flash another firmware and it said 'Passed' in Odin but the phone didnt reboot after 2 or 3 mins so I just restarted it myself and it went back to the annoying 'UPDATE' screen, do I need to wait for Odin to reboot the phone and does it take a while?

Cheers
[Galaxy S II General] mrchrisrueda:
CSC and modem are all in tar file, its just one file you need to put in pda then start...it will took awhile to reboot for a newly flashd rom:)
[Galaxy S II General] dkennedy1001:
Thank you, im at work so couldnt see what was in the file so thanks for letting me know. Maybe last time I rushed and didnt give my phone time to reboot! i will give it longer tonight after Odin says passed!

Will let you know how I get on...
[Galaxy S II General] hole1none:
Did you use a pit file of i9100? Cause if not then the problem is that you are flashing an incompatible rom, to fix it you must download a stock rom for m250s or just load the pit file and rom of m250s. :)
[Galaxy S II General] raphaelmg:
Sorry for resurrecting this subject, but i have one shw-m250s too converted to i9100 and my vibration is very weak... :crying:
