phone re-locks after reboot Galaxy_S_Unlock - Galaxy S II Q&A, Help & Troubleshooting

I've been searching for answers all over the place with no luck… Maybe somebody can help!
I am setting up a Galaxy S2 from Virgin and want to unlock to use on Rogers, I use the app Galaxy S Unlock which I have used in the past… It works, but after reboot, It locks again, I get the message for the PIN…
Any idea!?!?!?

My GS2 is factory unlocked, but i've been reading some of the GS3 forums and a similar issue happened on late samsung firmwares, there's a fix for that phone but im not sure if it'll work on ours. Its probable related to a recent firmware, you should try flashing an older one and see if the issue persists.

[Q] T-Mo Vibrant SIM issue

Hello all
I recently got a great deal for a Vibrant (150$ contract free, looking brand new ).
I live in Europe and I already own a Galaxy S, so I thought "hacking" the Vibrand would be a piece of cake... well it wasn't Finally after reading a ton of stuff here on the forums I managed to beat it using Odin.
After finally getting root the first thing I did was to download Galaxy S unlocker from the Market so I could use it with a local SIM card... and it failed. The app couldn't find any codes? and neither the root or non-root method worked.
The Vibrant recognizes that there's a SIM card, and even asks me for a PIN on boot... then nothing happens. When I try to make a call, "Data network not available" is displayed.
The network here is GSM 900/1800.
I'm currently on the deodexed KB5 2.2 ROM flashed via CWM.
Any help would be greatly appreciated
Hmm...I believe there was another method to unlocking it other than the Galaxy S unlocker program you have. It will require root which you have.
Search around the Vibrant forums, I think it was from at least a few months back.

Yes, I found it but I'm not sure wheter it's a lock issue (it said "no codes found") or I have to flash an European modem or something. I'll try it anyway and report any results.
No luck
All the methods work for 2.1 and I'm on Froyo KB5.
Plus it's not really an unlock code issue..
It's rather... the SIM card doing nothing.
- Is it insearted?
Yes
- Does the phone recognize there's a SIM card?
Yes
- If you have a PIN, does it ask for it on boot?
Yes
- Well what's wrong then?
I can't do anything else with the SIM... not even join a network
Did you per any chance lock your SIM card with a PIN code?
Cause if you did, it is asking for the code that you locked it with. . .
Try another, UNLOCKED SIM card just to be sure that's not the issue.
The phone SHOULD ask you for an unlock code only. A pin code request (unless you are reading the unlock code as a pin code) means the SIM card is locked.
The card was unlocked, I put the PIN on purpose later, just to see if it'd recognize that
Then what is the issue? Without the PIN, it recognizes the SIM and loads up fine but doesn't get on any network?
Yes!
And that way it's just a VERY overpowered iPod touch. Would be nice if I could actually make phone calls from it, but if not - whatever.
I remember anything above 2.1 theres an issue with the SGS unlocker on the market. I had to use a different method, and I don't remember where I received the instructions from, but I did find this for you on youtube. Please do watch the whole video as the person has the same problem, but runs you through the steps to unlocking by using a different method.

gosh... no dice.
The phone never asks me for any unlock code, just stuck on "Searching"
Try a different modem. If not then try a different rom..may be?
Why not just odin back to stock,reroot, and try to unlock it before flashing a rom

[Q] No Sound or Networks after unlocking

Hi,
I used this method to unlock my Samsung Galaxy ace yesterday, unfortunately, when I restarted the phone, it just hung when the Samsung logo shows up.
I flashed the S5830XXKPH and AceVillainRom, but unfortunately on both there is no sound and the phone doesn't detect any cellular networks (wifi working OK).
I cannot install a 2.2 ROM, because once flashed, the phone freezes on the Samsung boot logo.
Now I have the official unlock code from my cellular network, but I don't know how to apply it, since the phone doesn't detect any network at all.
Update: I noticed the IMEI is not set on the device, maybe this could cause it to not be able to search for networks, is there any way to set IMEI back to default?
I would be grateful for all your suggestions.
same problem here, i wish someone would help us.
The Search button isn't there for nothing . There's a thread that teaches you how to downgrade in the Android Developmeny section .

yep, but this problem can't be fixed easily, that unlock method spoils the phone, you need to take it for repairers

Couldnt agree more. If flashing other roms doesnt solve ur problem, send for repair is ur only solution. Tampering with efs partition is proven dangerous on ace.

As its a BETA product it might be worth emailing the dev via Goole Play .

How do i do that? I talked to the voodoo support (through the play store) but they are not willing to help

Same problem here,ive used voodoo sim unlock and sim fix,but still nothing happened,but when i dial the confirmation it says "network lock is off" dont know what to do now.
voodoo
i had this same problem . What i do is click out sim card but dont fully remove it . Unlock the phone using voodoo, back out of the app an click sim card in again . Leave it 4 a lil bit and hopefully the sim card locked shud disappear and it will ask you for your sim pin .If it doesnt work on ur first time be patient and try again. Although everytime the phone powers off it locks the network again
Hi, i was having the same problem here. Mine is a i9300 from Claro PR. This happened to me with the stock rom( it seems like all the Claro's bloatware is affecting this). I just installed a custom rom and it works perfectly now.
Hi
has anybody got this or any other method to work on the latest Jelly bean leak ROM?
I had to flash back as i was un able to sim unlock.
Does this mean we will have to get a Official unlock code to use Jelly Bean 4.1.1 in future?
i know there is a patch for vodoo but can't find it anymore

well im new and a bit confused myself here, but my wife got me a lovely new 32Gig s3 i9300 from vodafone on contract last month. I rooted it but cant remember what rom I put on it, then this week I got hammered to accept a upgrade to the BUBLG3 firmware I think. so I got annoyed when a few apps stopped working and decided I wanted to unlock and unbrand this thing, I spent the last two days chasing both a firmware upgrade only to be utterly confused as to which one is the latest unbranded rom and as to how to unlock the phone, I got the voodoo unlocker from somewhere and when I ran it it said Sim Lock: inactive. which surprised me a lot so I typed in *#7465625# and my imei to find out more, turns out that it says that command is unknown ?, with or without the imei. Then I threw in a O2 sim out of curiosity and lo and behold it works, so I am guessing either the Rom I loaded up and was overwritten ( or however it works ) unlocked it or it was unlocked when I got it from Vodafone. So many Roms floating about its very confusing to me and probably a lot of noobs which to get. Still cant get the apps to load either.
Sorry if this is of no use to you but i thought it was interesting and in context with the post header.

Hi
i think youll find most Vodaphone phones are SIM free.
I had a Galaxy Nexus on Vodaphone which I ordered through Phones4U which was also Factory unlocked
I have my s3 rooted some guy in a phone shop done it. If it's rooted does it definitely mean he's installed a different rom on it or has he just opened the superuser access.

If it's rooted it doesn't mean he's flashed another ROM at all. Just means you now have superuser access.

Network Unlock Control Key

Looking for some help or suggestion as this problem came up out of no where.
using XWLPM Unbranded, Unlock Version. phone working with TELUS Canadian carrier. out of no where, all the sudden im getting the prompt of Enter Network Unlock Control Key. not getting any signal with the SIM card.
My SIM do not believe is locked and nor is the firmware. anyone have the same problem or know what the heck is going on as im running a unlock 4.0.4 XWLPM version and not sure how to get rid of that.
Thanks:crying:

since ver 4.0.4 has some issues, would suggest u to rewert back to stock 4.0.3 and then see if the issue persists, if its not there then stay with v4.0.3 untill a stable v4.0.4 is released
ps- do not make any wipes in recovery, or backup ur phone with the same with v4.0.4 since the same can potentially brick ur phone
SIM is not dead. turn out to be a phone issue. not resolved yet but find it very strange how it can go from non-lock to locked with network control key prompt.
used GSII repair from the market, it resolved the issue but now the phone is unable to turn on any security pattern prompt for instance, and it has a weird box logo right on the home screen.
anyone had this problem before?
Yes I've suddenly had this issue, but found the app 'Galaxy_S Unlock' on the market which quickly resolved my phone being locked.
But the problem persists as it randomly locks itself again, and I have to use this app again, bit of a pain as this is a work phone, but luckily it still unlocks with this app.
Looking for a permanent solution, anyone have any ideas what the real issue is here, and yes I'm using v4.o4 firmware on my phone.
My SII just got the OTA update to 4.04 this morning and is now doing the same thing, my carrier is pretty indifferent as its unlocked so I'm trying to get help out of Samsung. Mostly adding my 2c to give the topic a bump
Same trouble here after a flash to Resurrection v3.0.5, prompt of Enter Network Unlock Control Key.
Tried the unlock apps from the market and no go, tried flashing a few other Roms, restored a few nandroid backups, factory resets and still nothing. Put the SIM into my backup phone to test and no problems with that.
Strange when accessing the menu at *#7465625# the network locks were listed as off.
What did work for me was to flash back to the original stock Rom that came with the phone (KG2 Bell). After the reboot there was still no signal so I entered stock recovery and did a factory reset, cleared cache partition/dalvik cache, fix permisions and reboot.
After that all has been working good and was able to flash back to my nandroid backup.
I just packed it off to Samsung, they didn't admit fault but the phone is out of warranty but they are fixing it free of charge. Smells like victory..

[Q] Unlocking an s3 on UK orange

Hi there, this is my first post on this forum so I apologize if this is in the wrong place. I have recently purchased an s3 (GT-I9300) used, on orange network. When the phone boots, the orange network logo is displayed. I rooted the phone using CF-Auto-Root-m0-m0xx-gti9300 using odin , and i have checked, and it is succesfully rooted. This was my first root on a phone, and seemed to go well. I have not installed anything else using odin. Then I went about to unlock the phone, getting numerous unlocking apps (ariza patch, galaxsim unlock, galaxy S unlock, voodoo s3 unlock) but they all do nothing, saying they have unlocked it but my talkmobile micro sim (which runs off vodaphones network) will not work in the phone, it just asks me for a network key, then says emrgency calls only, and if i try to dial anything, says 'not registered on network'. I have not tried another sim in it yet as that was the only microsim I had.
My question is, can I unlock this phone in any other way, like would taking it to a market stall unlocker, or buying a code from the internet do the trick? and also, will I be able to install custom roms on this phone safely? Im not sure if the orange bootloader affects this in any way. Thankyou for reading, any help would be greatly appreciated
