Bought an I9300 s3 on eBay is locked to O2
Vodafone sim
Spoke to O2 no help at all. Call 202?
Doesn't make calls.
I've got an efs backup but from the 4.1.2 current stock.
Seems this won't downgrade to 4.1.1
Odined the stock 4.1.1 no joy. Won't boot.
Cwm an old miui 4.1.1 also no boot.
Odin back to stock unbranded 4.1.2 boots fine. Rooted cwm triangle away. Fine.
Whos is this phone? Apparently not mine.
How to down grade please?
Any help gratefully appreciated.
Super wipe after flashing rom helps.
Downgrade to 4.1.1 probably won't have SDS fix so may kill your phone.
If it doesn't make calls with O2 sim then IMEI may be blocked. It won't make calls on Vodafone, because it's locked to O2.
You have to factory reset if it wont boot.

So you're saying after cwm the 4.1.1 I should full wipe.
Then the business.
Then flash a safe kernel before upgrading back.
If I just odin the 4.1.2 stock back over surely the brick bug won't activate?
Flash 4.1.1, full wipe. Do your unlocking, flash 4.1.2

This went badly wrong.
Flashed stock region correct. 4.1.1
Flashed chainfire cwm root.
To allow wipe
Booted fine.
The fix as follows doesn't work as the final menu still not available.
Just dial the following keys *#197328640#Main Menu[1] UMTS*[1] Debug Screen*[8] Phone Control*[6] Network Lock*Options [3]Perso SHA256 OFF*(after choosing this option, wait about 30 seconds, then go back one step by pressing the Menu button then select Back, now you are in*[6] Network Lock then choose*[4] NW Lock NV Data INITIALLIZ ..... wait for a minute then reboot your phone
Even though I didn't execute anything as that menu option isn't there something bad happened.
I installed galaxsimunlock from the play store.
It now says invalid imei.
Glad I backed that up.
Still locked.
The saga continues
I would try an O2 sim before anything to see if the phone actually works or not .
Blocked phone are blocked via IMEI and require the blocking network to remove the block .
Report phone stolen network block IMEI get new phone sell the now blocked phone is fairly typical .
jje
If I buy an unlock code on the Web or at a store will it sort of the blocking from the network?
Don't know anyone with a micro sim on O2.
Thanks for your times
Edit.
I flashed back to 4.1.2 its ok. The baseband doesn't get replaced on downgrade and isn't understood by the older software. There is a post somewhere here about it.
This is what causes the odd error messages in that unlock app. Currently says can't read nv
Unlock code will do nothing if the IMEI is blocked, the phone is useless.
Take it to a phone store, for a small fee they will tell you if it is locked or blocked.

Are you now saying the phone is blocked ???
If so return to the seller / Ebay .
Unlock code will not remove blocked IMEI .
Usual reason for a block is phone is stolen

I agree if it turns out to be blocked I will. It was PayPal so he must be verified.
But I still don't know anyone with a micro sim. Shame they're not all the same size now.
I was just checking ahead of time. I don't want to pay £15 for a code and it not work.
I work weekends so I'll have to wait until Monday.
Thanks everyone you're being very helpful. Much appreciated.
Good news everybody!
We've got a delivery to...
- found someone with an O2 micro sim.
Works fine on O2.
Seems I'll have to go pay for a code online or in one of those seedy little shops.
Seems a shame. As I can alter my /efs backup and presumably restore it back.
If only I knew which file/s to change.
It's not the most obvious one that contains only three letters O2U
Unless galaxsimunlock doesn't restore properly.
Galaxsim unlock is fine. But you have to pay now because he removed the beta / free apk from his xda thread

I agree galaxsim unlock would be great. But as it now flashes a red bar
"Unable to read nv data"
And offers no option to unlock or pay. Cos it says in the help that it doesnt know it can unlock the phone.
I'll have to wait for an upgrade.

Just because it shows the 3 welcome screen doesn't mean it's not unlocked, just branded. If you continue past the welcome screen, are you sure your Orange SIM doesn't work? If so, what method did you use to SIM-unlock it?
Thx a lot for the reply.
Initially i have used Chainfrie's Galaxy S2 sim unlock. but didn't work. Then i have used Helroze's Galaxy_S unlock. After that i pressd *#7465625# it says
Network lock OFF
Network Subset lock OFF
SP Lock OFF
By this way i believe its unlocked. But dont know its really unlocked.
Cheers
Tony
Branded means network branding and add on .
Your is 3 branded
Locked means locked to a network unlocked and it will work on any network .

Not recognize sim first question has to be does it reconize any other sim .Second question have you entered the network settings for orange ???

Mr jje,

By the info youve given already your phone should be unlocked. Will it not make or receive calls or is it just the web that aint working? Does the sim card work in another phone?

Sorry to jump on this thred but noticed the OP had the same kernel, build and baseband numbers as my newly bought S2.
Ive been looking about for the right files to download to root mine but have been puzzled by the right ones to get.
Which are the corect kernel and firmware files I need?
Currently on Three network also looking to unlock and debrand.
Hope you can help

Only two possible answers left .
One you have not entered your networks settings or they are wrong .
If you have then phone is not unlocked .
Simple test .
Phone works with original sim = software OK .
Other sim works in another phone = sim ok
Phone works on another network sim after network setting have been entered if not then its not unlocked phone .

thx for all your support. its working now
Hello
i have rooted my phone because i need to use a different sim. Because i was with 3 it wont let me to use a different sim even after rooting and unlocking it.
The only way if u want to use a different sim is to flash a unbranded official uk firmware on it.Because even if u unlocked the phone after rooting all the bloat ware and the fiemware from 3 wont let u use any other sim (i mean in my case.) but make sure u have already backed up the current firmware before flashing a new firmware.
Please use method only if u bold enough to do it. because if u done anything wrong it may void the warranty.Please do all this in your own risk, to overcome this use a jig u can buy from ebay. or goole it or there is lots of information about this in you tube to reset the flash counter
I will explain what i did to my phone
Step1, Rooted my phone using the method described in android authority and firmware xwlp7 which is described on the above site. here is the link for it please copy and paste on your browser then u will see the method how to do it.
http://www.google.co.uk/url?sa=t&rc...xMSnBw&usg=AFQjCNEAJtIUKzYLRTUMggMwJWe2V-SseA
Step 2,Once u have rooted Get the sim unlock apps from Google play, in my case the Chain fires one didn't work, use this app only once, if u use it more than once u r phone may get locked. Then i have tried Helroz's Galaxy_S Unlock and it did worked.You can check this by typing *#7465625# in u r dial pad once the app run and if u r phone is unlocked it will say sim lock 'OFF'.
But at this stage my phone wasn't working with my other orange sim . The reason was the phone was still on 3 uk firmware that's why the phone wont let me to use any other sim. So i need to find a unbranded original firm ware close to XWLP7 which was my original firmware because i don't really want to try any other firm ware.
So i have found that carphone warehouse uk was using XWLP7 firmware in their sgs2 which is same as mine. Because phones from carphone ware house can use any sim i thought this may work with any sim on my phone as well, You can get this from SAMWARE site where u can find all the firmwares for sgs2, new and old. This site is free and only need a registration. Down load it and extract it in to a folder(tar file). Once you are in the site look for the carphone ware house uk's firmware. I hope you are in Ice cream sandwich 4.0.3
Step 3, Before flashing this do a back up of your current firmware just in case if anything goes wrong , u can flash back. U can do that in recovery mode, (Turn your phone off, turn it back on again by pressing volup+home+power) U have options there to back up, once you done the back up of original firmware in the reoverymode
Step 4, Do a factory wipe/ reset
Step 5, Do a cache wipe as well on the recovery mode this will help u to do a fresh start.
Step 6, Tun the phone off again and turn it on back on down load mode( vol down+home+power button)
Step 7, Start odin which you have used to root the phone in step 1 then connect the phone using the usb cable and odin will recognise your phone (yellow colour on the left hand corner of the odin page) Once this is seen on the pda choose the firmware you have downloaded ( carphone ware house oen from SAMWARE) And make sure only reboot and F.reset time and pda are checked,make sure nothig else checked in the odin. Then let it run, this will take few mins and the phone will reboot.
Hope fully this time u don't see any 3 welcome screen, turn it off and try using the 3 sim first, it should work then try any other sim, in my case that was orange it did worked fine including mobile data so you don't have to change the APN settings for each network provider.
Thanks for the xda develpers, android authority and samware for all their hard work in providing lots of information.
Any doubt let me know. Please do not do anything unless you are really comfortable with
Thx
Go to any of the supermarkets and buy a PAYG sim from another network,{around £1.00}, youi don't have to register the sim to see if your phone is unlocked.
{EDIT} I see you said your coming from a iphone.... So that means its a cut down sim {micro-sim} card.
Parhaps it is not seated in the correct position.
Just a thought..
My phone is doing the exact same thing, can anybody help?
Originally on three UK. Got unlocked in a shop. Orange sim card worked fine. Restored to factory defaults to erase phone. Orange sim card no longer works, but phone is showing as unlocked. Every other network sim card works fine.
Its bugging me, took it back to the shop where i got it unlocked and the man said he had never seen anything like it.
Any help would be great. Thanks
Hi all,
First of all, I want to say thanks for all the help and knowledge I've found on this website - it's amazing.
I've come to you because my sister bought an i5500 from a girl who was on the Telus network in Canada. My sister is on SaskTel, and I believed I would be able to unlock it after looking at xda-dev for some time. After several hours of rooting and attempting unlock, I finally got the BML5 file and opened it in hex editor. After several more hours, I managed to locate my SIM unlock code - 01234567 (Which I find odd, by the way).
Anyway, my sister has since gotten a SIM card from SaskTel and when we insert it, no SIM code prompt appears. I then tried it with my Fido card, and it did the exact same thing - the phone acts as though there isn't any SIM card in. It does, however, state that there's no signal.
Does this mean that the phone is already unlocked? If it is unlocked, I don't know how it happened - the girl that originally owned the phone never hacked the phone or anything. If it is unlocked, why won't my Fido SIM card, or my sister's SaskTel SIM card work?
The other issue I've been having is that the phone will suddenly turn off every 5 or 10 minutes. Could it have happened when I rooted the phone? I used SuperOneClick to do it, then command prompt to pull the img file to my laptop. Did I partially brick it?
Thank you so much for any help you guys can give me; I'd like to think of myself as fairly technically apt, but at the moment, I'm completely at a loss as to how to fix this.
Again, thanks.
---------
EDIT: Found some new info: Whenever the phone restarts, the date, time, and time zone are all reset back to standard. Does this mean that the battery is shot? The phone is less than a year old...
useful thread
Well I don't know about the rebooting, but what I recommend you read this thread,
http://forum.xda-developers.com/showthread.php?t=1335548
specially the last part, which states:
Most custom roms that tries to remove blur break the subsidy lock interface (sim unlock screen doesn't show on them). If you flash other rom and subsidy unlock screen doesn't pop when you insert foreign sim, you will need to flash back stock ROM in order to unlock. So the easyest way for those of you running a Custom ROM, just do a nandroid backup using CWM, flash Stock ROM, unlock your phone then restore your backup.

Thanks for this. I used that link to root and get the code for the phone, but now I'm confused with the lack of PIN unlocking screen. Does that mean that I'm going to have to backup/flash with stock ROM? I'm totally fine with flashing it back to stock if it's not, in fact, I've looked for a stock ROM in case that was the issue. Since it's a Canadian model though, (GT-I5500M) I can't find any. There's a list somewhere on XDA with all the I5500 ROMs, but it says that there aren't any from Canada. Options? Ideas?
Thanks again for the help.
Anyone with any other ideas? Right now I'm trying to decide whether or not we should just sell the phone and get a new one, so any advice/help would be appreciated so much.

Thanks, I did, but there isn't anything for Canada on there. A new problem just cropped up: the WiFi won't turn on. So, even if I wanted to flash it with an official firmware, I don't think I could - I have to use the market to download an app to flash, right?

After breaking my "/efs" folder (IMEI) though a dodgy flash, I began looking at how to flash a new one (well, what's written on the sticker under the battery).
Finding that there is software and hardware combinations that can achieve this, hope was looking up, especially as my month old Galaxy S3 is uninsured.
"Universalbox" is one of the devices I stumbled across that can changet your IMEI number back to what it originally was, amoungst other stuff such as unlocking, but you needed to buy the $250 device, the $2 UART cable (have them both shipped to the UK) THEN pay the micropayment inside the software to achieve this.
I wish I had that kinda money, but sadly, being unemployed and living on my own doesn't allow for new gadgets very often at all.
HOWEVER. I popped into a mobile phone repair (and unlocking) shop and notices hundreds of UART cables on hangers on the wall. So I enquired about it.
I was quoted £15 which I really can't argue with, obviously they asked if it was stolen and I just said that all I want is to have the IMEI number that is on the sticker reapplied. Not asking for anything illegal, just to fix the software fault.
I get paid on Wednesday, so I'll let you all know how it goes.
tl;dr, If your IMEI number is screwed, ask around the local unlock shops.

If your IMEI number isn't the same as the one on the box, or sticker behind the battery, I'm afraid you'll have to go into a phone repair shop and tell them you need the IMEI restoring. That's assuming, like me, you don't have a backup.
At first I got the "We can't do that, it's probably stolen", but after explaining that it's just corrupted and all I want is it reverting back to the one written on the back of the phone, there wasn't a problem.
I'll let you know if my problem gets fixed tomorrow.
To find out what the device's current IMEI number is, either:
Open up the "Phone" application and dial in *#06#
or
Settings -> About Device -> Status

Is there a Mac version perchance that works with the GT-I9300?
Hi guys,
I've messed up and need help. Here goes...
I had a locked phone on the 3 network , a S3 I9300; and I wanted to unlock it. Simple I thought to myself.....anyways, I downloaded the voodoo unlocker after rooting successfully with Odin. Nothing happened it wouldn't read my T-Mobile sim card and I can't remember what I did exactly but I did press some buttons on that app in attempt to unlock the sim. I then realised that it was not compatible with the S3 and then I proceeded to use the GalaxSim app. I had to download busybox for that, after doing that I attempted to unlock it. Yipeee! Phone unlocked and everything green.....but not. I still couldn't register on any network(using manual method as well). I had even cleaned my SIM card(but not tried another sim card). I then unrooted the phone with stock rom and unrooted again to use GalaxSim......and pressed backup accidentally! That I means I am now with an unlocked efs folder as my default efs, I didn't check the IMEI number to see if it changed, but how I return it all to normal? Has my IMEI number changed or would it not show IMEI if I overwrote the EFS folder?
I need help, I'm confused.
What phone you post I9100 ?????
No or broken EFS then just restore your backed up EFS .
jje
sorry i9300.
No, the EFS I had was overwritten with the newer version when I reinstalled the app. Now I have only one EFS and that's the one currently installed(which says the phone is unlocked). The phone is not registering on any network. Is this a baseband issue or a unlock issue? The app is showing unlocked, it shows all the networks, but some are written as"forbidden networks" and I can't connect to any.
By the looks of it, the simlock will never return.

You cannot update an EFS with a newer version you can only restore your original backed up EFS .
Does the IMEI match that under the battery if not its a service centre repair .
jje
Oh and the platform is jellybean.
The imei is the same, but it is still "sim unlock". How can i redo the process?
your phone should be fine you restore your original imei or just copied your origanal imei again probaly for the best as you know you have a back up of it now
chances are your phones unlocked now and probaly just need to register the sim card with T-mobile to activate it
should always place the back up of your efs somewhere else aswell incase things do go wrong mem cards can corrupt
Both sims that i've used are contract. I can't register any. They all say disconnected on status settings.

Hi to all on xda!
I have recently bought GT-I9300 from friend. When he wanted to sell to me he updated to 4.1.2 stock rom but after update he got error no sim. Now i'm trying to fix it for me. I don't know what version was before but now is XXEMG4. I've checked everything on phone and everything is fine (imei, s/n, wifi, gps..). I done update via odin once again and that pass well but the problem stays. I think maybe sim card get locked. I read over forum that i can unlock sim via *#197328640# but when i select [6] NETWORK LOCK i get error (menu not exist..). I read that i need 4.1.1 stock for this command and if this is xxemg4 update efs is v2 so i can't go back to 4.1.1, right? Can anyone help me? Please...
*UPDATE*
When i go to recovery mode on screen is this:

but my csc is MSR, that rom i installed. Can this be reason for no sim issue?
Network lock is not responsible for no sim message, that's usually due to a faulty sim card or card reader.
Try your sim in another phone and another sim in your phone.
You can't go back to pre EMG rom, the csc is unimportant, there is currently no way to network unlock your phone without a valid unlock code.
All the above is already posted many times, please search instead of creating new threads.
i have searched for this problem but i found only similar topics not same as mine. I have signal so i dont think it is modem faulty also my sim card works on another s3...

In that case if you have read the faqs then you need a service centre repair .
Or simply pay for the network unlock as you have been instructed to .

How on earth does that answers the question posted .
I have tried couple of patched modems but cant solve problem. When i flash patched MG4 modem then i dont have imei and s/n is wrong and instead showing some signal as did it before now is crossed circle icon. I tried that to restore efs backup but imei still was null/null. Then i flashed rom again and imei returns also s/n and no sim card error.
When i try to call then i get message "Not registered on network"...
Take it to a service centre, you won't fix it yourself.

Hi to all on xda!
I have recently bought GT-I9300 from friend. When he wanted to sell to me he updated to 4.1.2 stock rom but after update he got error no sim. Now i'm trying to fix it for me. I don't know what version was before but now is XXEMG4. I've checked everything on phone and everything is fine (imei, s/n, wifi, gps..). I done update via odin once again and that pass well but the problem stays. I think maybe sim card get locked. I read over forum that i can unlock sim via *#197328640# but when i select [6] NETWORK LOCK i get error (menu not exist..). I read that i need 4.1.1 stock for this command and if this is xxemg4 update efs is v2 so i can't go back to 4.1.1, right? Can anyone help me? Please...
*UPDATE*
When i go to recovery mode on screen is this:
# MANUAL MODE #

Basically they meant two things.

Give a thank if i helped you.
They also want to repair for 200 euro!!!??? Replacing motherboard and sim card reader. Why they want to replace it if it is software error?
User flashing error, not covered by warranty.

The reason is that it has failed warranty status .
Due to wrong firmware but more often phone is rooted or had custom rom and signs have not been removed .
Samsung's warranty is not the sellers warranty and they have a much stricter policy .

I will let you know when i try. I hope too because it also error me no sim card....
No, same error. I will try 4.3 version now...
i found this service manual: http://mobilcoms.ru/load/1-1-0-4505
Has anyone know how i can check voltage on R324 (pdf 08-... page 12)? It is under sim/sd card module. Do i need just battery or i need sim and to turn on phone? Has anyone tried this?
I officially announce that my i9300 is fixed. Problem was in sim card slot (some pins were bent). I take apart my phone i start inspecting it. Checked everything from service manual and it was fine but after i remove sticker on sim card slot i saw that one pin is bent (Vcc) so i use small needle and gently rise that contact up. One side of contact is soldered so you must bent up behind solder. i reassemble phone and power on i waiting for result...No service, ok this is normal, as every time so next is no sim error but then signal bar started showing some reception and SMS from carrier started comming. Problem was in sim card slot....200E saved . Thread can be closed!
