This conversion works using JB ROM????

You were of great help. thanks
[Galaxy S II General] DrDieBrein:
Hi there thanks for sharing this info.

It worked to convert a M250K to i9100. But it does not register on network no matter which sim card I enter. So I tried to revert back to m250, but it's not working. I use the PIT provided in the quoted post, and a firmware I got from http://xdaforums.com/galaxy-s2/general/korean-galaxy-phones-firmware-jelly-bean-t2421728 I used the first one listed there. But it fails in ODIN and says it failed to write.

Can anyone help me with my issue? Also if someone could help to fix the network not working then I wouldn't even need to revert back to M250. When I try to run a USSD with a sim card inside it just says Not Registered on Network.

Did you tried to check your IMEI to make sure its valid ? recently i found a site where you can find some useful info...

[Galaxy S II General] digital_ranma:
I'm also having a problem reverting back to the original firmware for SHW-M250K. Odin reported is as a successful reflash but the device is stuck in the samsung logo. I also noticed that the meter/indicator on the device would just be half way through before it rebooted. Flashing it to the i9100 firmware though again didn't encounter any problems whatsoever. The lockscreeen and power button bug is the main reason i want to revert back to the original. Please help. :(
[Galaxy S II General] digital_ranma:
Update: I manage to solve this on my own, and as a helping hand to those out there with similar problems just like mine, instead of using the latest version of Odin3, use an older one. I used Odin3 v1.87 and the update to Jelly Bean pushed through without any problems whatsoever. :D
[Galaxy S II General] digital_ranma:
Is there any way to root SHW-M250K without having to flash it to i9100 stock rom?
[Galaxy S II General] Bivav:
Yes there is a way to root your Korean model without having it to flash i9100. I can't post the link here as i'm a new user so i might as well explain you.

The post was posted by 'shindatuin', a senior member.

Steps:

1. You MUST Save file to external sd card (find a 1gb sd card for 5mins as it will take only 5 mins)

2. Shut down

3. Open stock recovery (press power + vol up + home button)

4. Navigate to "Install zip from external sd card"

5. Select the file "CWM-SuperSU-v0.97.zip

Wait and reboot

Congrats you rooted!!

Note: This superuser file needs to be updated from play store though.

Hit thanks if it helped or contact me if you have any doubts.

Cheers!! :)
[Galaxy S II General] digital_ranma:
Wow! Thanks bro! [emoji4]

Lost IMEI and no signal

I am new to xda, I have recently converted my SHW-250S to I9100 successfully but lost my IMEI(Changed to 0049) and after upgrade not connecting to any network.

Came along many forums and they were saying to replace the efs folder. To my bad, I haven't taken efs folder backup.

Can anybody guide me the correct procedure to get back signal and IMEI

- got the Korean SII SHW-M250K and I tried flash from 2.3 to 4.1.

- I downloaded the 4.1 from sammobile, and another 4.1 from other site

- I tried ODIN 3.07, 3.04 a 1.85

- already install samsung drivers

- tried 2 pc's, the win 7 and win 8

- tried samsung kies for firmware and it says SHW-M250K doesn't support initialization

- ALWAYS SAME ERROR (and yes, I have other Samsung device and ODIN always worked with it, so don't blame my pc)

phone won't boot, won't boot to recovery.
[Galaxy S II General] Bivav:
Hey,

This might be a late suggest or help but either the way, don't worry about the lockscreen and power button issue. It can be solved easily.

If you still have converted i9100 rooted device then follow these steps:

1. Download any root explorer.

2. Navigate to the root folder: /efs/imei

3. Press left soft key or menu key and Create a new file named as "keystr"

4. After creating the file, press and hold it & open it in text editor and write "ON"

5. Set the file("keystr") permissions to rwx rwx rwx ( press & hold the keystr file & select permissions and set all to rw)

6. Reboot your device.

---------- Post added at 03:26 PM ---------- Previous post was at 03:15 PM ----------

That's a quite surprise issue. I still use Shw-m250k and shw-m250s devices. I upgraded both devices without any issue. Samsung kies supports it.

The phone still doesn't boot? Can you turn on? Did you hard reset the device and tried unistalling drivers from computer and let kies install it?

Maybe try another usb cable?(don't think this is a issue)

---------- Post added at 03:33 PM ---------- Previous post was at 03:26 PM ----------

The samsung galaxy s(series) korean device model with L (m250"L") seems to be a very complicated device. Did you search well before you flashed it? Try a clean and full reset using recovery. If the problem still exists reflash to stock rom. Search the forum well and then try again.

Hope it helps!

Cheers!!
[Galaxy S II General] RenatoNismo:
- when I try to turn on, normally, recovery or hard reset, the screen shows -> http://i.imgur.com/kmnHrii.jpg

- only download mode works. impossible to boot or hard reset, because I tried flash odin, the progress became stuck and I had to cancel/unplug it.

-my brother's samsung S7562 europe always worked well being flashed on my 2 pc's and with any usb cable.

- samsung kies didn't help nothing, says SHW-M250K doesn't support initialization

where did you download the firmwares ? from sammobile ? if not, could you provide to me ?

the samsung was android 2.3, I didn't found the 4.0, so that's why I flashed directly 2.3 to 4.1.. and the progress became stuck on 2 different md5 4.1.

also I have the firmware of i9100 + the pit file, but I didn't take a risk, I'm afraid of losing IMEI (my friends wants this phone for unlock SIM card and use it)
[Galaxy S II General] Bivav:
okay.. i didn't flash directly from 2.3 to 4.1.2(the latest for samsung s2). I had to update 2 time to reach 4.1.2 through kies. Hmm.. did you try to flash 2.3 again back? I think the problem is you jumped from Gingerbread to JellyBean leaving ICS, bootloader problem. Gingerbread to jelly bean latest may have quite updated bootloaders. That's probably you messed up.

I know this site by Calvin lee. It has all the files you need, i guess.

http://dabinslab.blogspot.sg/2013/03/turn-shw-250sk-to-gt-i9100.html

I think he has in the download section of SHW-M250K 4.0.3 ICS ROM(UC08) and SHW-M250K 4.1.2 ROM (ML1- latest).

Download the 4.0.3 and flash it rather than installing directly to jellybean. (just my recommendation). Then if you succeed and the kies recognizes it then install latest version from it.

Also I flashed to i9100 and had only 2 problems. Lock screen pattern and power button. Which can be solved easily.

Hope it helps :)

Tell me if you need anything else.
[Galaxy S II General] RenatoNismo:
couldn't find the 4.0 firmwares before flashing 4.1, and couldn't find the 2.3 to try revive back.. these were big problem for me, downloads for this version of SII are almost inexistent.

will try this method later.
[Galaxy S II General] Bivav:
Yes it is hard to find official ROM for S2 nowadays but you'll find it somewhere. The link I provided has downloads for 4.0.3 and 4.1.2 both.

The thing is, I am wondering, why didn't you backup the ROM before you flashed it? You should backup ANYTHING before flashing, even if it is just for the heck of it.

Anyways, try flashing these firmwares. If you still can't boot and still stuck in download mode then there are other tricks you could try.

Cheers!
[Galaxy S II General] RenatoNismo:
I didn't backup because I flashed every phones in my hand and never had problems, and this phone didn't have nothing important information.

flashed the 4.0.3 and finally the progress in odin went to 100% and the phone revived, that's what I needed, thanks for the link. I will flash jellybean and then use some app or any method for unlock sim card, anyone experienced this ?
[Galaxy S II General] Bivav:
Congrats for succeeding.

Backing up your user data is your wish, I was saying about ROMs mainly. Taking precaution is better than suffering like you were, isn't it?

I never had problem in sim card lock with korean mobiles. Although I know this link for RegionLock Away app by [MENTION=631273]Chainfire[/MENTION] . Try it and do share the information :)

Cheers to your succession in flashing!

Also, Hitting some thanks would be great for someone who helps you mate.
[Galaxy S II General] RenatoNismo:
tried to flash differents 4.1 versions with odin, no luck. then tried kies and it worked like charm. strange

with 4.1, used galaxsim and framaroot, both worked fine.

then converted SHW-M250K to I9100 and it went everything fine, SIM still unlocked and received SMS.

now time for search CM11 :D
[Galaxy S II General] Bivav:
Told you at beginning to let it upgrade through kies after 4.0.x version ;)

Did you not face any problems when locking your device and unlocking? The screen lock feature actually dies out. You'll need to fix it.

CM11 is just great :)

This is the download page if you are searching and search for i9100 in search option and install it.

Congrats in flashing success! :good:

[Galaxy S II General] Bivav:
First,

You flashed from which firmware to 2.3.4?

Second,

Can you boot to recovery? If yes, try hard reset maybe?

Third,

Hi !

Can I replace the motherboard in a m250s by a i9100 motherboard ?

My wide has a m250s with a corrupted IMEI and very often the network won't work. Now we live in France and I was wondering if I can buy a used i9100 here with a faulty screen (so this is cheap, I thin kI can get one for 40€ or so) and install the motherboard in her phone.
[Galaxy S II General] Bivav:
Yes you can upgrade to latest version. Use samsung kies to update to 4.1.2 then flash Philz cwm6 to root.

---------- Post added at 03:23 PM ---------- Previous post was at 03:19 PM ----------

Seriously motherboard? Galaxy S2 motherboard? Why would you want to do that? That device is technically a outdated in today's world although i'm still using it by modifying to other firmwares. My point is: You could get new phone with that replacing motherboard price. Won't you?

Sent from my GT-I9100 running CyanogenMod
[Galaxy S II General] benoitb85:
What phone do you suggest at 40€ ? With similar camera quality as a Galaxy S2.
[Galaxy S II General] Bivav:
You must be kidding bro. 40€ for a mobile phone? Add 40 more and i guess you can buy the latest Android One from Google. I don't know about your place but I get in my country.

And about replacing motherboard. Motherboard is the core chip inside a phone. Why would you wanna go that much of trouble in fixing the phone with hardware replacement? Maybe it's software problem. Try fixing the problem. Google is your friend here. If it works congrats your 40€ is saved. If it doesn't, yea you can definitely try your way.

Cheers!!

[Galaxy S II General] RaphaelBarros:
Does this work for any m250k? I mean, mine is 4.1.2, baseband M250KKKJML1

I want to root it so I can backup my EFS folder before trying to convert it to I9100. Last time I tried converting without a EFS backup I couldn't make any calls (it screwed my IMEI) and the only solution was to go to technical assistance. I'm glad they didn't charge anything :).

Anyway. after converting to a I9100, has anyone successfully installed a Kitkat or Lollipop rom?

I think we should create another thread for this cellphone, or maybe contact the OP so we can compile every important info on the first post. It's really troublesome to find information that actually works for your version of the phone in a 212 page topic.
[Galaxy S II General] Bivav:
Hello there!!

Yes! As I have mentioned that it will work for Korean Model (i.e m250k and m250s but not sure about m250L). Sure no worries with 4.1.2 since it is the last update till now. Really? You lost IMEI? I have flashed to i9100 with some problems which I solved but not IMEI problem. Anyways you can root so you can backup ;)

Yes I have successfully installed Kitkat as well as Lollipop ROM. Right now I have Lollipop running :)

DONE!!

Search and ask a lot before you flash it without much knowledge :)

[MENTION=5678801]Bivav[/MENTION] Thank you very much, now my phone is rooted. I'll try backuping the **** out of it and then I'll try your procedures to convert it to I9100 and then install lollipop.

Thx a lot, very informative and organized post :)
[Galaxy S II General] Bivav:
Sure No problem. Follow the link to convert to i9100 http://lankatechbuzz.blogspot.com/2013/07/convert-samsung-korean-s2-into-international-samsung-galaxy-s2.html

Do remember that there will be some lock screen problems but it can be easily solved. There is steps in that link.
[Galaxy S II General] RaphaelBarros:
Just one last question: this link you gave was just to root right? When I boot into recovery it doesn't go into CWM. Do you have a working version of CWM to m250k? I want to make a full nandroid backup just in case.

Thx!
[Galaxy S II General] Bivav:
No, the link converts your korean model to GT i9100. Don't worry you'll not lose IMEI. There is process to recover that at the end of LINK

If you did not get how to convert here is the process:

1. First check what firmware your device is running. If ICS then follow full steps BUT if Jellybean 4.1.2 then download the "PIT file gti9100" and "JellyBean International" and follow STEP 1 directly but remember to put PIT file with jellybean international file because you need it to convert to i9100.

2. Once you convert to JellyBean international you will have some problems. There are solutions too so follow that and you'll be fine.

3. After you convert to i9100 then you can flash the recovery cwm that I gave you the link in earlier post. I did not have for korean model. Don't worry you'll lose IMEI but you'll 100% recover it :)
[Galaxy S II General] RaphaelBarros:
Again, thx a lot! I'm now using CM 11 on my M250K (now a I9100 :P) \o/

When CM 12.1 becomes stable enough, I'll also give it a try :)

Thx!
[Galaxy S II General] Bivav:
Sure! No worries... No hurry as well... Android 5.1.1 is out and has some bugs but I am being able to use it as my daily device! The thing is we need a good partition to install android 5. It requires 1GB phone storage just to install and Samsung S2 has default 2GB. So you cannot flash FULL GAPPS Because there will be no space Also If we install many apps then the Phone Storage will have no space very fast.

The solution is If we can get a proper PIT file to flash and make that 2GB default to 4GB. But I'm finding it hard because I already tried and I nearly bricked the device.

Anyways I don't install many apps so I can use it nicely.

Just thought you should know about it :)

Cheers!!
[Galaxy S II General] RaphaelBarros:
I guess using a link2sd like app could do the trick. Do you know if it's possible to partition our phone using Heimdall?
[Galaxy S II General] Bivav:
Correct me if I'm wrong,

Link2SD app is for transferring almost all apps data to SD card. Yes it is a kind of a way to save space in phone memory but I don't think it's for changing (increasing or decreasing) the phone memory.

Heimdall is open source tool which I used long time back but not now and I like it but I prefer ODIN to flash. I think it's possible to flash from Heimdall but the problem is we need to find the proper "PIT" file first. Flashing is no issue.
[Galaxy S II General] signupstuffid:
Thanks to all who have contributed to this thread. I have a friends M250S that I updated from Korean GB to Korean ICS via Kies. All went well with the update.

I understand the conversion process for this phone to get it to be an I9100 requires I flash it with a I9100 ROM that is also ICS. Specifically not a 4.0.3 ICS ROM to avoid brick bug.

But I can't seem to find a link to a stock ICS I9100 ROM anywhere.

Does it work just as well with JB based ROMs?

So I can just update via Kies to Stock JB

* then use towel root, install custom recovery

* back-up the IMEI

* then Odin flash a JB based stock I9100 ROM.

* then flash custom I9100 ROMs?

* Then use root explorer to fix the lock screen problem as shown in link below

http://lankatechbuzz.blogspot.com/2...-s2-into-international-samsung-galaxy-s2.html

Is this all the steps in the right order?

When I flash CM 11 via custom firmware, do I need to do the unlock fix again?

Thanks again.
[Galaxy S II General] sunyakram:
i convert my 250s to i9100 but lost my imei and didn't backed up my efs , and every time i want to revert back to stock odin failed my installation and brick my phone,then i again install i9100 firmware with same PC same odin version without any problem, my problem is not registered on network ,i dont care about a fake imei , any help? thanks in advance :)
[Galaxy S II General] sunyakram:
any help?
[Galaxy S II General] Bivav:
This might be a late suggest or help but either the way, I think you have taken the conversion process a little wrong way. If you have JB stock in M250S then just install Stock GT-I9100 with the pit file included. in process You'll succeed. You'll lose IMEI but you can get it easily.

After you convert to Stock gti9100 then root it and fix IMEI and Screen lock.

Installing Custom ROM is pretty much easy after conversion.

1. Download ROM and GAPPS and put it in your external sd card.

2. Install custom recovery using ODIN. Install custom recovery that allow you to install KitKat.

3. Got to recovery mode.

4. Format everything and clear cache and dalvik cache.

5. Install from zip and flash ROM then GAPPS.

Done

CM11 or CM 12 are rooted already. To install android 5.1 is also easy after installing CM 11

See this link : https://www.youtube.com/watch?v=svHYITCoSW8

AND NO You'll not have to fix unlock the screen if you already did in Jelly Bean.

Cheers!!

---------- Post added at 02:51 AM ---------- Previous post was at 02:44 AM ----------

It might be a late reply but still....

To fix Imei you need to root your device.

If you have converted i9100 rooted device then follow these steps:

1. Download any root explorer.

2. Navigate to the root folder: /efs/imei

3. Press left soft key or menu key and Create a new file named as "keystr"

4. After creating the file, press and hold it & open it in text editor and write "ON"

5. Set the file("keystr") permissions to rwx rwx rwx ( press & hold the keystr file & select permissions and set all to rw)

6. Reboot your device.

This will fix your lock screen as well and your signal as well.

After that why not try to install Custom ROM and get rid of irritating TouchWiz??

Try CM11 or CM 12.

See this link to install 5.1 android in samsung galaxy s2.

https://www.youtube.com/watch?v=svHYITCoSW8

The process is same to install CM 11 and CM 12 but first YOU NEED CUSTOM RECOVERY!! Look above post.
