Looks like you erased the EFS folder. Do you see a Mac address in about the phone?

What's the objective of checking and testing dial codes?
I've never heard of that.

It's meant for diagnostic purposes to test the phone by trained personal, not for the general public unless you know what you're doing.

I doubt it was your objective but it looks like it's your end result.
There's a lot of new posters in these forums who have done stuff thats screwed with their phones. XDA is brilliant but it's not magic.

Tbh after I'd asked I kinda thought it may be something like that. I'd be gutted if I screwed up to the point of having an unusable phone.

Well... I'm no expert... But it sounds like you bought a phone that is meant to be an upgrade to someone's contract, so it comes paired/tied to that contract's phone number, he/she probably didn't want to upgrade, so they sold it to you... After you reset it, it needs to be set up by the original phone number/sim card it came paired with... So the solution is probably to contact the person you bought it from and explain the situation... See if there's anything they can do to help you...
I bought the G6, and so I gave my G4 to my kid brother after factory resetting it... When he was setting it up... It requested that He would login with the previous google account that was being used on that G4, which was mine... So I had to login, and then he could set up his own account and the phone as his, now the phone is tied to his account... I believe this is an anti-theft prevention or something like that... Only mine was tied to my Google account, and yours seems to be tied to the networks sim card... When you reset the phone with that code... I believe you resetted it to the very original state where it was still tied to the networks no. with which it was supposed to work with... Maybe if you had resetted it from the settings menu, it would still be ok.
Anyway, those are my 2 cents... Hope it helps!

Contact the person you bought it from... And maybe ask if it is possible for you to mail them the phone, so they can set it up with the sim... Then, you'd switch the account... Or take it to an LG support center, and explain the situation, show them proof that you bought it... They can probably wipe it clean... Or you can also try flashing an unbranded network fre .kdz firmware file, that is compatible with your model... That might "detach it" from the original sim card it is requesting... It's worth a try.

Currently I'm another one victim of the same problem, and I'm outside the USA also.
I wish to repeat unlocking of the phone, but I couldn't find the code to show me the window, where I have to input an unlocking code.
2945#*933#, 2945#*71001# or 2945#*20001# do not work for me (no any reaction from the phone).
Does anybody have some more ideas?

Thank you for the reply. Is it something like what lmiked told about, or another action?
Where can I learn about steps I have to perform to do this repeat unlock using Gcpro or an other boxes? I've found that it is the bootloader unlocking tool. So do I need to do some next steps after I have unlocked my bootloader?
Currently I am able to go in phones bootloader and I see the option to reset the phone to its original state (done, does not help) and to flash some files from flash card. But I don't any files to flash.

Where can I find unbranded network firmware file and which tool I have to use to flash it to the device?

You bought a Sprint locked device, this one can only be sim unlocked to work internationally, that unlock is done by Sprint as far as I know.
The bootloader on this phone is not unlockable, and the firmware cannot be changed. You might want you return the phone if the seller told you it was unlockable/etc., because it isn't.

Problem with unlocking Rogers x10a

Hi all, I'm new here and before I tell you the problem, I appreciate all the info on these forums and the work that is put into everything. Thank you in advance.
So, I have a locked Rogers branded X10a, and I was unable to get the SIM unlock pin. So, I got the network unlock code, but whatever sim I put in, the screen always reads "no sim card" in the phone and then the activating screen loads and continues to load forever. Under settings (without a sim in the phone), there is the option for sim unlock pin, but that is the code that I am unable to get after numerous tries on different sites.
How can I get to the screen to enter the sim network unlock code if the phone in not recognizing any sim cards that I put in? Btw, I'm using AT&T. Any help would be greatly appreciated. Sorry for the length of this post and thank you.
I had similar issue my w580i. I had it after putting the unlocking code it stop recoganising SIM, havn't solution till now
Did you try using a different Rogers sim?
I don't have a rogers SIM, only AT&T. I bought the phone locked and just figured I would be able to get an unlock code like all the other phones I've had before, but no dice.
Check your pm
Sent from my X10a using XDA App
I just tried to put in my deactivated Rogers SIM card from long time ago, and I am also getting "No SIM Card" ... Not sure if your problem has anything to do with Rogers Wireless used to be "Rogers AT&T" before
If you have any friends has SIM card from different carriers, try to put those in and see if you experience "No SIM Card" issue.
Regards
Mabye it does.. I'll try and find someone with a Tmobile sim I guess.. thanks for the advice though..
Please keep me updated on this, I'm trying to unlock my X10, I got the code from cellunlock.net through the manufacturer and keeps telling me after I enter the code that it was unsuccessful.
I still can't unlock my phone either but I'm not sure about the SIM unlock code you're talking about. Are you talking about the IMEI? or the actual code that's used to unlock the phone? I've tried Mobileincanada.com but they couldn't unlock my phone and gave me a refund and I'm still waiting for this dealer on ebay. Good luck dude, keep us posted

Got an unlock code, www.cellunlock.net
Make sure to pick the Sony Ericsson Manufacturer code it's 34.99 but well worth it. It works now.
the manufacturer unlock code is the one I got, but I just don't get the option to put it in because the phone doesn't recognize the AT&T sims that I've put into it...

How old are the sim cards? If they are old, get new ones. Also, try re-installing the firmware through seus and then putting in your sim card. I never had that issue, I just had a hard time finding the code.
I had a real old one from cingular, but then I just went to AT&T and got a brand new one, but same issue. I'll try updating and see if that helps, but will the phone update without a valid sim inserted?

I had that same problem. Call AT&T or go to your AT&T account online and get the PUK number. Also, did you call AT&T and told them you have a new phone? They need your phone's new IMEI number.

I'm sorry, what is the PUK number for and also, why does AT&T need my IMEI number? I mean, the phone is still locked to rogers right now regardless, right?
Lots of noob questions, sorry.
Also, i already spoke to AT&T, Rogers and Sony Ericsson about the issue, but none of them are any help of course. The PUK did nothing for me either. I feel like I am running out of options here...
welcome to the club
http://forum.xda-developers.com/showthread.php?t=717414&highlight=phone+stuck
so far no solution
So, I tried repairing through PC Companion and then I also ran the update and go the newest firmware installed now, but still same problem. Phone does not recognize the AT&T when inserted and therefore, no option to enter the network unlock code. Any others have any luck/make any progress??
wow... i guess i'm in the club as well. I just got back from the Rogers store and they wouldn't let me replace the phone anymore. I've bought the manufacturer's code which is suppose to work 100% but it didn't...so desperate
Sorry to hear that...
You said the code you got didn't work? In what way? did you try to get a refund by providing video evidence?
On a side note, does anyone know how to access a keypad on the x10 that enables you to imput the left arrow, *, * left arrow method to input the code? I realize I need to have a valid rogers sim inserted in order for this to work, but I do not see how to input the arrow keys. Any suggestions? As I've said, I'm new to android and to a device with no physical keyboard, so maybe this is very simple...
thanks and good luck to others in the same spot as me right now..

T-Mobile

Is there anybody that would be able to call T-Mobile to get me the Unlock Code for my Samsung Vibrant, if I give them my IMEI.
I had my phone unlocked and for some reason it randomly locked up again.
I would call T-mobile myself, but I am not with them and I live in Canada.
If anyone could help me that would be greatly appreciated.
Thanks in advance!!
T-Mobile gives former eligible customers free unlock codes.

Unfotunately I don't think it will work. The phone has to have been registered on the users account, meaning the user must have put their sim in the phone before, or there has to be proof that exact phone with the IMEI was purchased from T-Mobile by the account holder.
But luckily for you, if you were a T-mobile customer in the past, and you did in fact use that Vibrant on their network, they will provide you the unlock code again.
For your reference
http://support.t-mobile.com/doc/tm51885.xml
"T-Mobile will provide the SIM Unlock Code upon request to eligible former customers, provided that T-Mobile has such code or can obtain it from the manufacturer. "
Who knows though, might work, if you are willing to find someone to try it for you.
Yeah i am pretty sure the person who had the phone before wad with t mobile, so it should be fine. I just need someone who is with t mobile to call in for me since i am not with tmobile.
There was an app in the app store that'll give you the unlock code. That's how I unlocked mine. Check the market as it was a free app.

You don't need to even bother with that. Use this thread to fix the unlock. This will make it more permanent. Hopefully. It worked for me on two different devices. Cheers!
Thanks for the responses..
Yeah I unlocked my phone myself a month ago and for some reason It became locked again randomly. Dont know why... I just dont want to go through all that work again, and have it happen again... If I get the Sim Unlock code then it wont be a problem, and I can just put in the # again. When I originally tried to get the number through the SGS Unlocker it just gave me 8 zeros, so that method dident work.
The computer that I am using does not have all the drivers and crap and it is not my computer so I do not want to load everything on it.
If anyone with T-Mobile dosent mind calling for me that would be greatly appreciated.

The problem is you can't use the sim unlock code once you have gone through this process that they would send you. If you went through that process, then the code is whatever you set. If you don't remember what that number is, then you will have to do it all over again.
It is not that i do.not remember. I put in eight zeros in. But some everything was reset and it is locked again. I tried the eight zeros and it sosent work. I think i used a different nethod. I did not use the batch files. I used adb and edited the nv data. I am pretty sure if i were to get the sim unlock from t.mobile it will work. I dident choose 0000000 as a sim code it just told me to enter that in the instructions.

The problem is that number replaced the old msl. So you have no choice.
What do you mean Msl?
Msl = master subsidy lock aka unlock code

vs995 ¨not sim card inserted¨ got it from ebay seller: guarantee cellular

I would like to know if someone could help me, i got a V20 VS995
I bought a cell phone that is supposed to be unlocked and when I put the sim card, it does not recognize it, I tried with 4 sim cards and it does not recognizes it, it always get the same message ´sim card not inserted´
the ebay seller told me to reset the phone and also reset the network settings, and switch the phone from global to lte / gsm / umts, and this does not work either. the phone also does not let you save a new apn, the apn list is empty and there is no way you can add a new apn.
and so, I updated the phone to the latest version and the same message keeps appearing... ´sim card not inserted´so I downgrade the firmware 2 times (stock) and at this moment it has the first firmware again:
VS99512A
B16.LGE.VS995.0
COMPILATION NUMBER
NRD90M
I also try the app
hiddenmenucall and when selecting the option lg hidden menu or OIT hidden menu the application closes (does not work)
I am not root
What else can I do?

Seller does not have to respond, call paypal and say the item is not as advertised and you got something different. You are protected up to 180 days with paypal, file a claim with them. But if you bought the phone, stated: broken parts or not working, paypal will not return your money. As you have been warned that its not working and you buying the phone as is. The only thing to do at this point is try paypal, if that does not work, file a chargeback with your credit card company. Keep in mind, that if you do that, you need to provide proof and details and transactions and may take few months or so to resolve. They will give you the credit in the meantime, but if they find out, its not a valid reason they will take back your credit until the investigation is complete.

Phone Not Allowed - UK SM-G950F

Hi All
I'm at my wits end with this Samsung S8 phone, Bought a 2nd hand S8, was working fine, but I noticed the internal storage was only showing 9.63GB
Had a look on here and the solution was to stock flash the phone. I did that, all fine, storage was back to normal....BUT since then I can't make or receive any calls.
I get the error "phone not allowed" and it won't connect to ANY mobile network.
I've tried loads of different suggestions
Sim is OK in another phone
Re Flashed (numerous times)
Andriod 7 and 8
Sim and Phone OK with three network
But still have the issue....
Can anyone help me? or push me in the right direction?
Cheers
Tommy
You probably tried this, but try booting into safe mode. If it works then there is a software problem. If the problems persist in safe mode you probably gotta contact Samsung.
Are you sure the phone is unlocked?

Is the phone blacklisted? if it is blacklisted then it will not connect to service. Your SIM wil work perfect in any other phone.
Hate to say this but it does sound like your phone has been blacklisted.
You can check with one of the online IMEI blacklists.
If your phone shows Phone not allowed and a code like MM#6, it usually is an indication that it was blacklisted.
Check your phone's IMEI on a blacklist checker like http://imeipro.info/
The previous user most likely had the firmware and baseband messed around with and once you flashed stock it reverted to true state, it's highly advised to get back in contact with the person, where was the phone bought? A shop? Online?

Yeah tried that , still the same
If one is in possesion of a S8 that says "Phone not allowed", and the phone is blacklisted, is there any way of fixing that?
I have the same issue here..
I bought an S8 from Manchester last summer, and I started using it last week, (because my other phone worked longer than expected) and after I gave the phone the Network key that the previous user wrote down for me, then that message appeared.
So im stuck with this almost completely new brick aswell...
Any options at all?

The only real solution here is to either go abroad and sell the phone, or sell it to someone who is going abroad. The phone will work outside of the UK.
It does sound as your phones imei Nr is blocked in UK.. Probably the person who sold you the phone, stole it somewhere.
I have the same problem on my Samsung S7 now in Brazil.
In Canada, on Canadian carriers, everything is fine, and if I put the Canadian SIM in there everything is fine. But the minute I plug in Brazilian SIM card, boom, Phone Not Allowed message comes up and it won't connect to any of the Brazilian networks. Brand new SIM, works just fine on another LG phone (and any other phone I tried).
The phone is unlocked, I even checked with a few pieces of software and there is no network lock on it either.
I've got the master & network unlock codes from Samsung, but have no way of inputting them as no prompts for those come up when I insert the Brazilian SIM.
I checked the IMEI, it is definitely clean and not blacklisted.
Heck, I even rooted the phone to see if that would help, and still nothing.
Any idea what else to try or what else might be causing this goddamn message to pop up?!
I solved my S8.
Blacklisted on all uk networks except Three network.
Works perfect.

LG V20 LS997 successfully unlocked with Oreo update

I finally unlocked my LG V20 LS997 (Sprint version). There is no trick.
I bought my LG V20 LS997 from ebay and the seller claimed it is unlocked. I called Sprint and they also told me the phone is unlocked domestically and internationally.
However when I put non-Sprint sim card, I always got invalid sim card icon in the status bar and cannot get the phone work. Many people had the same issues.
Some people can unlock it and work but after update to Oreo, the phone will be locked again.
I found place in Sprint community talking about the unlocked LG V20 but still getting invalid sim card. I read through all the articles one by one. And I found that there are basically three steps:
1) Update PRL;
2) Update Profile;
3) Unlock UICC;
I can do the first two without any problem. But I never succeeded in step 3. So in Sprint community, I sent Em_Will_I_Am (please remember this guy, he is really good and can help you out) a private message telling him my IMEI, ICCD(sim card) and what problem I had. He will check if the phone is unlocked in the system or not first and make sure the phone can be unlocked by Sprint standard (fully paid, not stole phone, no unpaid charge etc.). Since my phone is in good standing and can be unlocked. He first re-locked my phone and I had to restart my phone using ##72786# to reset network settings. After that he unlocked my phone. After I do ##72786# again and wait for my phone is hand-free activated and wait for several minutes. I did
1) Update PRL;
2) Update Profile;
3) Unlock UICC;
What I got was something like 'Your phone is unlocked to any UICC that supported by the phone.'
Then I removed my sprint sim card and into a H2O wireless (AT&T MVNO) sim card. It works! You have to manually configure the APN in order to get data working. Since this is Sprint version V20, it only support 3G in at&t network. But at least I can have voice and 3G data from other vendor. I tried rebooting my V20 and factory resetting my V20. All of these operations have no impact on accepting the non-Sprint sim card. It looks to me is really unlocked now. My LG V20 was update to Oreo OTA one week back. so it is on the latest version of android now.
Thanks a lot to Em_Will_I_Am. When he relocks and unlocks your phone, he basically sends out a signal and your phone will pop up and say 'Updating profile' and then 'Profile update is completed'. During the whole process, Em_Will_I_Am will send you private message to tell you what he did and what you need to do.
My LG V20 was still in Sprint network and was active. I don't know if you don't have your phone actively on Sprint network will that work. But I would suggest to send private message to Em_Will_I_Am and seek his help. He may be able to help.
How can I get in contact with him
How can I get contact with him?
I need help too. Bought V20 phone off ebay and it worked great for about 4 months with Straight Talk and Cricket and then it got the Oreo update and now it gives me the invalid SIM message. I never used it on Sprint but it was a Sprint phone. Any help would be appreciated or if you can pass along the way for me to contact the person that helped you that would be great.

I was able to contact Em_Will_I_Am and they helped me out. I think an unlock code was sent again. I also did a couple of things that I think finally allowed the unlock code to come through. I went into developer mode and turned on Enable OEM unlock and then powered off. Then I powered back on while holding the power button and volume down. When the menu came up I chose Wipe Cache Partition. Then when I rebooted it came up and recognized the SIM again and so far all is good. Thanks again to Em_Will_I_Am on the Sprint community forums for all the help.

Greetings.
I can confirm this. The Sprint assistant knows exactly how to solve the issue in just a few steps. Had the same problem associated to the phone locked since Oreo update and he helped me in a matter of few steps. Create the Sprint account and message him. He'll give you the support.
How long did it take for you to get the support?

I assumed I would need a Sprint sim to do this, so I just bought a new Sprint sim card off of ebay for a couple dollars. Then you will be able to give the sim information to Em_Will_I_Am
He'll put you on the list if your phone is able to be unlocked (ie. not blacklisted, not listed as stolen etc) and soon you'll be unlocked.
I'm so thankful to have found this thread and so thankful to Em_I_will for all his help. Amazingly helpful person.

I have the same problem; Em_Will_I_Am told me that I would be on the waiting list from last week and still no answer.
Could you please tell me more or less what time it took you to complete the unlocking process?

I waited just over a week. Keep in mind, they are done in the order they are received and I'm sure the first priority is dealing with customers actually staying with Sprint
Just keep your phone powered up so that you're ready when your time comes.
