Hi guys,
I read a couple of threads and tried a couple of things and didn't work... Im trying to sim unlock my Galaxy S4 GT I9500 on stock android 4.3 not rooted and is not working.
I read about a code using *#0011# code and didn't work.. Post was not specific about using no sim, original carrier sim or desire carrier sim.. anyway I tried all and was a failure.
I read another thread about flashing a modem and downgrading the firmware but wasnt specific enough about how to do it and the requirements (android version, rooted?, how to do it, etc)
I try one of those "code pages" and even they couldnt help me. My carrier is Movistar in Nicaragua.
Is there is any easy way to SIM unlock my phone? maybe by just installing a pre-rooted, pre-unlocked rom? or is there is a page/guide/video with specific instruction on how to do it?
thanks in advance.
I think the step by step instructions on SIM unlocking in the main thread on the topic are pretty specific. They don't mention downgrading the device modem through Odin however because they were written before Samsung patched the exploits that allowed the SIM unlock to work.
Downgrading the modem to an Android 4.2.2 version in the AP/PDA slot in Odin is necessary to run either unlock metbod. However, you can really mess things up trying to unlock if you aren't careful, especially with the service menu exploit.

Dear All
I am from UAE & bought Galaxy Tab yesterday. I have inserted my SIM and it is working fine but need to jump into upgrading firmware business
I have read many threads but got confused with the information. Can some expert please answer following :-
1. How can i check that my TAB is Factory Unlocked? I have checked using that *# code and it says all locks are off.
2. If my tab shows me that all locks are off, does this mean it will not get Locked if i upgrade the firmware?
3. I have currently
PDA: P1000JPJJ1
PHONE: P1000JXJJ1
CSC: P1000OJPJJ3
Can you please advice which version from samfirmwares.com i need to take for upgrading it? Currently its Arabic but i dont need Arabic. Can i install Euro version? If yes which one please?
3. Can i root & unlock all available firmwares? Should i root after upgrading firmware or before upgrading?
4. I was an iPhone user. So curious if firmware upgrade will also upgrade baseband and phone can be locked?

I dont have a tab (I may get one)
1) put a sim card in from another carrier
2) should do
3) use the samsung update utility
4) like iOS updates may block the root exploit but if it is factory unlocked then it shouldn't lock the tab
5) there may be baseband updates (my htc wildfire has had 2) and they didn't lock it
Thanks for your reply but one question is Unasnwered. How to ensure that my Tablet is Factory Unlocked before i upgrade?
Putting another sim will not confirm that it is Factory Unlocked as it can be unlocked using methods in this forum and then any SIM can be inserted. Same concept like iPhone... Right?

By factory unlocked do you mean so you flash stuff on it and do upgrades? If so you ll have to look at a rooting guide, they dont.come unlocked like that.
If its sim unlock puttin an other sim will tell you

I understand that to flash firmware and custom rom, i need to root it.
By factory unlock, i mean network unlock. It works with all SIMs now. I dont know if it is Network unlock from Factory or using methods described in these forums.
So concern is that if i upgrade to new or Euro firmware now, will is become network unlock again? If yes can i unlock it again on latest firmware?

Upgrading firmwares wont lock it if its unlocked. It will be in the same lock condition as it was before the update

Hi guys one of my friends bought a S4 in the US, It's AT&T locked SGH-I337 so can't use it with sim in our country (South Africa)We have two models of S4 here, the I9500&I9505. Was wondering what the right steps is to get the phone working? Must I root the phone and flash custom Rom & kernel or just unlock sim card? I'm not new to Rooting or flashing Roms but haven't fidled with carrier locked phones before. And is it possible to use custom Roms from At&t in other countries thanks in advance [emoji2]

The Sgh-i337 is basically the same as the gt-i9505 EXCEPT for ATT locking the bootloader on that model.
You CAN Sim unlock it so you can insert your Sim into it. You will have to reach it a bit though. It helps if you know what firmware is installed on the phone. If it is MDB, MDL, or MF3 it would be easier to do I believe. Either way look for the threads about unlocking.
If you have NEWER firmware then there are separate threads for it, and it will more than likely need to be rooted, flash a older modem, then perform the Sim unlock from the menu. If you cannot find the correct post I can help look for it later.
Just reply back with WHAT firmware and Baseband you have installed on the phone and we should be able to help you further.
If you do have MDB or MDL firmware do NOF update it...

Thanks for reply ,I have NC1 firmware and I used Method 3 on this guide http://forum.xda-developers.com/showthread.php?t=2595457 .SUCCESS!
Could you recommend a modem I could try other than MF3 as the signal isn't that great ?

Not sure which would work best for your area. You can download and try any/all of them until you find one that works best. You can switch back and forth with no issues without worries
Hi. I'm trying to unlock my S4 to use another sim. It's locked to EE. It's now been 2 years so I've got the S6 today. Giving the S4 to my partner.
I tried the *#0011# method. Can't get to the UMTS menu. Tried the Region Unlocker App without success. I tried downloading a random 4.2.2 ROM from the development section to access the Service Menu and I'm now stuck in a boot loop. I used to have 4.4.2 installed.
Please help?
Unlocking only works on stock ROMs. If you downloaded a Jellybean ROM from the development section, you're doing it wrong.
While the unlock methods used here do work if the directions are followed correctly, there's no guarantee the unlock will be retained with ROM updates or baseband changes. You're better off asking EE for an unlock code, or buying an unlock code. Unlike the unlock methods here, once that code is input, it unlock the device for good.
Questions belong in Q&A, not General.
Thank you.
Hello,
I've been digging the forums and the net if there is any way to sim unlock the i9506 for free.
All the tutorials, etc refers to the i9505 but not the i9506. I was not able to find any free solution to the date.
Does any one knows if there is any free method today in 2016? Maybe all the info I've found is outdated and old and perhaps there is a new way/method to sim unlock the S4 i9506.
I've downgraded to 4.4.2 and tried the *#0011# method without luck.
Any help would be appreciated. Thanks in advance.
The only free SIM unlock method for your device is asking your carrier for a code. SIM unlock worked on the I9505 by downgrading the firmware to Android 4.2.2 and then using one of the methods mentioned in the thread. The I9506 never had Android 4.2.2, thus no way to SIM unlock.
Hi,
I need to SIM unlock my N9005. The app "GalaxSim Unlock" says "Your device should be unlockabale if you downgrade your baseband to MJ2 or before". I live in Austria (Europe).
I'm familiar with changing the baseband but I can't find any MJ2 or before download-link.
Attached you can see the screenshots of GalaxSim Unlock and the request for an unlock code when I insert a simcard from another network provider.
Thank you very much!

It all depends on what firmware you are currently running. I'm pretty sure "MJ2" is Jelly Bean. If you've already upgraded to Lollipop, there is now way you'll be able to downgrade, something to do with upgrading your bootloader to Lollipop makes it impossible to downgrade to stock Jelly Bean from what I've read, but you can research yourself if you like. If you are still running Jelly Bean (which I doubt by the looks of your icons), you can flash this right here: http://updato.com/firmware-archive-select-model?record=9434E847231211E6949E0CC47A44B7B2
I'd recommend just buying an unlock code on the internet, it's much faster for one and you don't have to mess with flashing anything on your phone.
Goes without saying, I will not be responsible for anything that happens to your phone if you decide to flash the file I've shared with you. Please do your research.
Thank you for the hints. I bought the unlock code for 12€ and it's working
