Still trying to unlock (Stock TMob S4)

Just in case you missed it, one of the previous posters gave a hint for those of us who could not get to the Service Mode Menu after pressing menu-back-menu-1. Basically what you have to do is:

Press Menu

Press "Back"

Press Menu

Press "Key Input"

Enter "Q" (case-sensitive, no quotes), then 'Ok'

Press Menu

Press "Key Input"

Enter "u" (case-sensitive, no quotes), then 'Ok'

Press Menu

Press "Key Input"

Enter "0000" (4 zeroes), then 'Ok'

Then wait about 25 seconds and the Main Menu will appear

...........my problem is that when I get to the network lock step, all I see is "[1] PERSO SHA256 Info". When I touch that, I am taken to another screen that only has SHA256_ENABLE_FLAG [1]. If I touch that entry, I am taken back to the root menu and have to do the whole process above again to get back in.

I tried pressing Menu and entering "0" but just got booted out. Any thoughts?
[Galaxy S 4 General] Strephon Alkhalikoi:
Downgrade your modem to an Android 4.2.2 version then try the exploit. This exploit was patched in later versions of the modem.
[Galaxy S 4 General] Dandman808:
Ah, thank you. I will research how to do this a bit later - am a bit swamped at the moment. I will keep you posted.

Hi all, I need to sim unlock my i9505 from T-Mobile UK

I'm using this rom: [ROM][Android 5.0.2][FINAL][STABLE] AntaresOne & Alucard24's optimized CM12 builds, with baseband and modem XXUHOC6

I understand I need to use modem ME2 to access the service menu, can this be done on lollipop or do I need to downgrade my rom too?

Cheers

Unlock code problem..

Hey everyone i've been doing unlocking for S4 Galaxy D0c0m0 SC-04E from Japan.

I've been following the procedures of Service mode menu and successfully unlocked 2-3 mobile phones (SC-04E).

Recently I've bought another one and i m following that method and when i put unofficial sim it asks me for unlock code.

Is that method is no longer valid or patched?

Can anyone help me in it please :(

Hi there I would flash the modem again. Try that. This is what I did as mine was locked to ee. what I did. I put custom firmware on my phone i9505 android lollipop then I rooted it and installed super user on to it after that I installed region away unlock . I then tried all different simcard in and it worked a treat. After that I restored the phone and it wiped off region away . And the phone is still unlocked . I'm just your average user . There may be a better way of doing this but this worked for me. . I haven't had time to thank everyone yet. Hope this helps let us know how you get on

[Galaxy S 4 General] dangerdred:
Tried unlocking another i9505 4.4.2 Vodafone Ireland today. First thing I did was root the phone. Odin failed when I tried to flash CF-Autoroot. I was left with the phone stuck on the 'Firmware upgrade encountered an issue; screen. Download mode still worked. I tried reflashing the stock rom back on but kept getting a fail with either no PIT file or else write fail after it OK'd the PIT file. I tried different USB ports and different versions of Odin. I tried Kies also. Eventually I tried the stock rom with the PIT file from this thread and Odin failed again. I then tried flashing the PIT file only in Odin 1.85 and it passed. :) I managed to flash the 4.2.2 modem and run Region Lock away and got the phone unlocked. Just a heads-up for anyone else who has this problem
[Galaxy S 4 General] diesalweasel:
Hi that good news then. What modem firmware did you use was it me2 I think it is. I've got one one vodafone I think that locked here in the uk can't try it because screen is smashed and I'm waiting for one . But as soon as I get it . I will give it your method ago. If you restore the phone region lock will disappear and phone will still be unlocked tried and tested
[Galaxy S 4 General] dangerdred:
Not sure if it was patched..

RegionLock Away won't work for you?

Modem I flashed is DXUAMDE2 and yes...once RegionLock Away is run and the phone unlocks successfully the locked status hasn't returned after installing any other rom afterwards for me on 2 phones at this stage

samsung s4 on rhree unlock

Hi everyone

I bought a samsung i9505 locked to three UK and I would like to unlock it. I flashed new firmware to get rid of three logo. Do I have to flash back an original firmware before start unlocking? and what modem i have to flash XXUAME2 or DXUAMDE2 or something else?
[Galaxy S 4 General] mihirat:
So it is a bit strange,

I rooted my phone using CF-Auto-Root

I flashed with Odin the ME2 modem only (XXUAME2 for my case) using the PHONE bouton

I used RegionLock Away

and no sim code phone is working but it losing signal i have to use settings to choose the mobile operator.

I decided to do the tutorial from the 1st post and woila invalid sin enter a pin. After factory reset sim is accepted but no service although the phone accepts calls
[Galaxy S 4 General] metafaniel:
Can't Unlock SIM either, here's what I've tried so far

Hi everyone. I haven't been able to SIM unlock my Samsung Galaxy S4 GT-I9500 phone either :crying: My phone it's rooted. I'll list all the methods I've tried and nothing has helped me so far. Here they are:

I've also followed the SIM Unlocking tutorial, but nothing happens when I press "Menu/Back/Input Code/1", and with this method I can't access Service Mode menu.

Reading and reading, I've found another way to get access to ServiceMode, and it's the following:

Press Menu

Press "Back"

Press Menu

Press "Key Input"

Enter "Q0000" (case-sensitive, those are 4 zeroes, no quotes), then 'Ok'

Then wait about 10 seconds and the Main Menu will appear

Doing this, I've read the following menus has to be accesed to disable the lock:

Select [1] DEBUG SCREEN

Select [8] PHONE CONTROL

Select [6] NETWORK LOCK

Supposedly there has to be an option called "[1] PERSO SHA256 Info" but in my case it appears as "MENU NOT EXIST Current Command is 186" and I don't know what to do next...

I've tried the RegionLock Away app:

I select the Region Unlock option.

The message "It appears the patch was succesfull" appears.

I touch the "Reboot" option but it doesn't reboots by itself. After a manual reboot, the phone it's still locked....

The app recommends do a second reboot, and even so, I'm still SIM locked............. :(

Someone suggested trying a paid app GalaxSim Unlock which claims to support Galaxy S4, so I gave it a try. But after it ran it's process this message appears: "Your device contains a new locking system which is not supported yet.", so FAIL again :rolleyes:

Finally I've read I have to change my phone using Odin and that I need to be on ME2 (baseband?) but that sounds too risky for me to try, I don't want to ruin my phone!

SOOO.... What can I do? Is there another way to try to SIM unlock this phone? Can somebody help me please?

My phone is rooted and these are the specifications:

Device model: Samsung Galaxy S4 GT-I9500

Baseband: I9500UBUFNA2

Product code: GT-I9500ZWLXTC

Platform: exynos5

ANY help will be appreciated, THANKS IN ADVANCE.

THANKS
[Galaxy S 4 General] Strephon Alkhalikoi:
You MUST downgrade your modem if you want either of these unlock methods to work. If you're unwilling to do so, paying for an unlock code is the only viable alternative open to you.
[Galaxy S 4 General] mistabeo:
I can't figure it out.. I'm on the ATT GS4. I have two phones, one of which I could get into service mode and unlock, and the other.. well, after following the instructions, it still hangs where it is. Here's a pic of it. Anyone have ideas? http://imgur.com/KySUoEL

I've also tried region lock... it says "successful," reboots, but it's still the same.
[Galaxy S 4 General] Strephon Alkhalikoi:
Did you downgrade the modem first?

RegionLock Away will always say it's successful, because its job is to remove the region locking mechanism on the S4. The unlocking of the S4 is an unintended side effect.
[Galaxy S 4 General] magus217:
But how can we now which is the perfect modem for downgrade? There are a lot of. Please help a bit.
[Galaxy S 4 General] Strephon Alkhalikoi:
All that matters here is that the modem you install be for Android 4.2.2 and be for your device so you can access the service menu or run RegionLock Away.
[Galaxy S 4 General] pablacho:
My device is on Android Lollipop (5.0.1, I9500XXUHOA7, baseband also I9500XXUHOA7), and I am worried that simply downgrading the modem to a 4.2.2 (or prev) one will fail catastrophically... Besides backing up EFS, is there anything else I should be aware off?? I am rooted and have installed lots of firmwares via Odin, but I've never done this particularly!

Thanks for helping :)
[Galaxy S 4 General] Strephon Alkhalikoi:
This is no different than installing the full firmware via Odin. The only thing different is that you're flashing just the modem. However, back up everything using Wanam's EFS Backup tool, as it backs up the modem partitions where the IMEI lives.

[Galaxy S 4 General] jay08:
before it reboots the "error" pops up like a label on the upper part of my phone. no other message. screen doesn't freeze, it simply reboots after showing "error"
[Galaxy S 4 General] jay08:
Can anybody help me on this?
[Galaxy S 4 General] Strephon Alkhalikoi:
Did you restore the modem after downgrading it? If you didn't, you need to. If you did, redo the process but turn Perso SHA 256 to "on". If the error goes away, then you know that method doesn't work for you, in which case you would use one of the other unlocking alternatives. If the error doesn't go away you'll need to have someone look at your S4.

restore the modem to what version? i'm getting confused to all the version i have already downloaded. do you mean ME2 modem? what is my other alternative in unlocking it? thanks for the earlier reply.
[Galaxy S 4 General] Strephon Alkhalikoi:
The version you originally had on the phone prior to you trying to unlock it. The other alternatives are RegionLock Away, which also requires you to downgrade the modem, or to purchase an unlock code through an unlocking service.
[Galaxy S 4 General] jay08:
Tried regionlockaway but it doesn't work as well. It works at first but when i put my phone to sleep or switch off then on the screen it becomes locked again. Which modem? Me2? Originally it was on a lollipop modem. It says here to downgrade in order for it to work. Downgraded to 4.2.2 with an mdm modem, can i unlock with this or i need to flash a particular modem? I'm sorry I'm getting confused with all the modems and downgrades I have done
[Galaxy S 4 General] Strephon Alkhalikoi:
If you're on Android 5.x, you would downgrade your modem to an Android 4.2.2 version, run either unlock process (I recommend RegionLock Away), then upgrade to the Android 5.x modem. If you purchase an unlock code or persuade your carrier to get you one you don't have to change modems.
[Galaxy S 4 General] diogen:
Have done this before and it worked. But not now...

Have an i9505 locked to Three (UK) running 4.4.2.

Flashing the ME2 modem, following the guide in OP, have no problems with the service menu...

After the handset reboots nothing has changed! Still locked to Three (i.e. asks for an unlock pin).

Tried doing the procedure with and without a "wrong" SIM inside.

Have NOT tried with a Three SIM inside (don't have one)...

Anybody can comment on this?

Anything special about Three?

Thanks.
[Galaxy S 4 General] Strephon Alkhalikoi:
Try RegionLock Away and see if that works. If it doesn't, you may have no choice but to pay for an unlock code, especially if you did everything correctly.

Hey there,

driving me crazy.

I have 3 simcards : on from original carrier, and 2 from another carrier. The phone was locked on original carrier, so i downgraded modem, did the OP instructions, and finally, with my sim card, tada, it worked after i had to do a regionunlock because it was asking for network code... : My simcard worked after reboot, as promised!

So i thought i was done, and put the second simcard, the one of my wife in the phone... and DAMNED, not unlocked!! Says not registered in network... no error message, it just doesn't allow to call or get 4G... just to be sure, i put back my simcard, and the original one... and the 2 are working ok!!

I really can't figure what's happening, since my wife and i are at the same carrier... any ideas on how to deal with it?

Hey all,

Apologies if this has been covered, I've searched the topic but not finding anything. With this modem it seems that the 3g signal drops whenever my phone goes into standby mode and is re-established after a short time.

Has anyone experienced this or have a fix? I am on a 4.4.2 ROM to try this out but haven't had any luck.

Thanks in advance for any help.

Hi All,

I have now managed to get this fixed by installing the XXUFNDG modem :). Last question, am I able to upgrade to Lollipop, or do I need to remain on KitKat for this to keep working?

I'm thinking on trying the VJUAMDE one. Thank you in advance.
