Problem unlocking vibrant

Hey I recently got a vibrant and have been trying tonged it unlocked. I sent the phone into samsung for a factory restore. When I got the phone back and tried to use the galaxy s unluckier and it would not give me a code. The application would return with "are you sure this is a galaxy s phone?". I rooted the phone and tried again with same result. I went on ebay and paid for an unlock code and it didn't work. I had the guy recheck the code and when he tried again the same code came back so it must be the correct code for my phone. I tried doing the i9000 hack that requires changing the data inside nv_data.bin to make the unlock code all0's. That didn't work either. Is there any reason the paid unlock code would not work if it was the correct code for my iemi? Is there anything I can do?

Omg, dude you have me freaking out over here. My Vibrant comes back from Samsung (where they restored it) on Monday! I don't even live in the US so I don't have many options. Please let me know if you get it figured out.
Edit: Wait a second, I think of heard about this problem before. If memory serves me, you have to flash it to another firmware (downgrade) for you to be able to unlock it. Can't recall which one though... run a search on here.
Here it is, try this post 107: http://forum.xda-developers.com/showthread.php?t=771158&page=11

I'm having errors also like yours, but you have already tried a code but i haven't cause i can't obtain my code. i'll just tell t mobile to give me the code.

Sorry to worry you. I dont know what they did, but the codes are no longer stored in the nv_data.bin file and where the unlock code should be its all F's. From what I read that happens when you update to froyo, but I never did and I verified the phone was not on froyo. So I went ahead and paid for the unlock code and when I got it and tried it, it sadly did not work. I thought it was maybe the incorrect code so I had the guy check it again and he got the same code back. He is going to credit me back what I paid, but I am affraid to try from someone else and get the same code. I am hoping someone can shed some light on a possible fix, I have tried flashing to various 2.1 releases and trying the code but it didnt work.

Yes I tried that method already. In fact I spent an entire day trying to get it to work. Every time it says network lock unsuccessful and doesnt unlock my phone.
Is that method suppose to work because I could never get it to. I followed the directions perfectly with no errors so i dont know. maybe I am using the wrong firmware, but since its posted in the i9000 forum I am guessing most of them use firmware for that phone. I have tried the original firmware, the one that came after that, and the very newest one. I think there were a couple in between.
Could anyone send me a good nv_data.bin, maybe I can inject my code into it and get it to work.

Did you manage to get it working? I would have sent you the nv_data.bin but I haven't received my phone as yet.
Just so I understand, did you ever have this phone unlocked? I mean before you sent it to Samsung, was it unlocked?

No I didn't get it working and it has never been unlocked
Sent from my X10a using XDA App

same thing for me except I never sent mine into Samsung, still on JI6 firmware and never flashed it with another rom...but the application says, no codes found
I recovered and there's a nv file there but after using 0xHex, I get FFFFFFFF and a bunch of numbers

i am having the same exact problems as u with my vibrant...i`ve tried everything the last 3 days and nothing...my nv_data.bin shows 0kb so if anyone could send me a good nv_data.bin also i would appreciate that....if it still doesnt work i will have to sell my phone because i have att thats why i am needing to unlock it

If you guys don't get anyone to send it, just send me a PM on Monday and i'll be glad to help.
I don't think I'm gonna have any problems as my phone was unlocked before. And I have the unlock code for it. In my haste, I misread and thought Laaf's phone was unlocked then came back from Samsung locked. Then he couldn't re-unlock it. My bad...

I had the same problem with my phone. I used this method:
Step 1
Punch this code into the dialer
*7465625*638*#
Step 2
Lock it to the MCC of the carrier you want to use.
http://en.wikipedia.org/wiki/Mobile_Network_Code
Here's a list
I think you need to flash to stock use to use this dialer code, I'm on Froyo and I can't use that code.
Good Luck. PM me if you need more help.

I don't think a nv_data.bin from someone else will do you any good, I am sure it would be their code , but I may be wrong ...
The problem is, way back , before you ever flashed any new rom or update, many threads stated, make a backup copy of your nv_data.bin, and you can restore it whenever you need it ...
I have flashed many many many custom roms and always restoring my phones original nv_data.bin allowed me to generate codes(I have unlocked it but did it just for testing purposes), and no matter what rom I flashed after restoring it always generates my same code.
soooo that being said, if you do not have your nv_data.bin, there are some hex edits you can do to the one with the F's in it, or you call tmo for the unlock code.
There are many threads on the subject.

Are you running JI6? Ive heard the sgs unlocker app will not work once youve updated. At least not so far.
Sent from my SGH-T959 using XDA App

I bought my phone with no contract so I just requested my unlock code from TMO.
Is a non-TMO sim card required for the unlock?

I got it unlocked but now the imei is wrong. Gotta figure out how to fix it. No backup of nv_data.bin so may be out of luck.

Unlocking Tmo Vibrant

June 2011 RE-EDIT... Use the instructions here or here to unlock.
EDIT: SIM-Lock on JI6 has been solved for me with helroz's repair_nv_data.zip, read further along...
Page 11, Post 103 has a good copy of the instructions (but read the whole thread)
Also, heres a link to the corresponding thread in the Captivate forums
Can someone who has had Tmobile US for at least 40 days put a request in for an unlock code for my Vibrant? I only have ATT and no friends with Tmo. The Tmobile unlock team already refused my request. You would just need to call Customer Service, ask for the unlock team. I tried all the solutions in the forums - I have a messed up nv_data (bought it on craigslist). Shoot me a PM if your willing to help. Thanks in advance.

how many days since you have your vibrant?
Sent from my SGH-T959 using XDA App

I bought it 2 days ago from a guy on craigslist

There is an apk you can get called sgs unlock and it will give you the unlock code

the sgs unlocker doesn't work if the vibrant's had the JI6 update flashed or any other custom ROMs in it.

I'm also trying to unlock my JI6 updated vibrant. I was a dumbass and didn't unlock it when it was on JFD.
I paid cellunlocker.net for a code, but apparently it takes up to 3 days to get the code.

Yup,it had ji6 when I got it, and tmo won't give me the code cause I'm not their customer
And abaybas, please let me know if the code you get works

In this case, would you be able to unlock it if you flash your phone with JFD stock ROM then flash it back to JI6?

Nope. I odin'd back to stock. Ive tried the fixes. I just need someone to contact tmo for me

Ill do it. Whats the imei on the phone? it can take up to 72hrs but most times when I call its less.

No need! Just got it unlocked with a file that helroz sent me
Repeat: You can unlock a JI6 flashed phone using a file that changes the SIM unlock code (I was running bionix fusion when i did it)
Someone please work with him to turn it into an app if thats possible... its just a couple bat files and a jar that edit the files i believe
Thanks so much french dude (helroz)

wow can't believe you can do that in JI6 update, cuz i know about one unlock method that erases your phone's IMEI number and unlocks it permanently but thats questionable to be.

he sent me a repair_nv_data.zip and it fixed my nv_data and maintained the imei thats listed under my battery

I am actually in the same situation. I cant get mine unlocked using the app because it doesnt give me an unlock code and just says 'are you sure this is a galaxy s phone?'. I also tried paying for a code and the code did not work, the guy who did it also retried a second time and the code was the same, so I dont know whats up with that. My IMEI is the same as whats on my original box. I tried hacking the nv_data.bin myself using the guide posted somewhere in the i9000 thread. If someone could send me that fix I would be very grateful.

why don't you try calling t-mobile and get your code?
the sgs unlocker won't work to me too. my only chance left is the code from t-mobile.

[Q] i337M Wifi/Network problems after flashing back to factory rom in ODIN

Can anyone Help me out here or try and lead me in the correct direction? So I tried to flash my Galaxy S4 i337M on BELL back to factory in odin. I used the I337MVLUAMDJ_I337MOYAAMDJ_I337MVLUAMDJ_HOME.tar.md5 But after flashing and booting up the phone Wi-Fi no longer works along with the phone either says "emergency calls only" or different SIM errors. I'm 100% sure the SIM works perfect I tested it in both or my other phones my Blackberry 9300 and my galaxy S3 and no problems. I have also downloaded that same bell rom from 3 different locations to see if rom downloaded incorrectly. The Phone is also rooted and has the philz_touch_5.18.2-jfltecan.tar.md5 recovery. Any help would be much appreciated.

cant say about the wifi issue, im having my own issues too..but download and flash the correct or compatible kernel for that rom .. that usually fixes sim errors or no signal

Do you have Knox issued in download mode? If so, you need to install 4.3 firmware only

Means you tripped knox. Warranty is now void, and knox itself cannot be used, which has some corporate implications, but if you dont use active sync then it doesn't matter. Now that youve done that, enjoy flashing whatever you want. Cf auto root will give you root, then id install clockworkmod myself via rom manager, and look for a rom to flash. If you wanna keep stock can use xposed to tweak.

so last night i flashed the bell 4.3 ROM and WiFi did start working. I do have signal however I'm still getting a unregistered Sim error. is there any kernel you would recommend? I'm willing to try anything at this point. I bought this phone and not more then a few days after getting it I screw my self out of using it.

If you flashed the stock rom, you'll already have the stock kernel. Did you perform factory resets after you flashed stock? You'll want to, i find it help. If you flashed back to odin with stock, and didn't unlock at some point, should auto assign apn, etc.
Can you confirm eimi and apn are correct? Did you clean flash? Wiping davlik, cache, and factory reset?

So guys i figured out my problem..... Which really sucks... so I bought this phone off of kijiji. the reason why my phone shows up as unrecognized sim is because apparently the phone is stolen.... after just getting off the phone with bell I found this out. so I'm out $450 bucks... I don't know if its possible but is there maybe anyway for me to revive this phone still? change the imei # maybe? idk...

You could unlock it i suppose and use on another carrier, you'd need to purchase a new sim or get one on a plan from a new carrier, unless it gets listed somehow. Not much experience with stolen handset. Maybe go back thru kijiji support and push for a refund.

I don't really wanna put anymore money into this phone if unlocking it doesn't work. and I tried to get a hold of the guy that sold the galaxy to me but no such luck. I think I just have a mini tablet on my hands? either that or a paper weight.

Sim card is like 50 bucks at most. Id unlock it (understand you'll lose LTE) and use a sim from another carrier. Can get them for travel or even online.

. I would unlock, and see if you can borrow a friends sim on a different carrier to make a few calls. If it works, try and get the new carrier to sell you a SIM. they may or may not, depends if the device comes back stolen for them too.
there are guides here you can use to unlock. Usually just a code and combination of presses to unlock. Don't need to pay for it. Search out a few guides. Isn't all that hard, and theres a few apps that do it too.

so just as you recommended I went on you tube and found a free way to unlock my phone. but even after unlocking it and using both a valid Koodo and Fido sims from my friends neither of them worked. both left with the same problem "unregistered sim / emergency calls only" So is there any real way to get my phone fixed? I dont think its possible to change the IMEI? not to imagine that its probably not legal... Any idea if I was to get a smashed s4 even if it was the i337M and say it was the US i337main motherboard would swapping it work?

BRICKED G935F , IMEI LOST PLEASE HELP.

Hi after flashing a rom not on xda my phone's IMEI became erased. unfortunately the EFI backup that I had wouldn't fix either. I tried going back to stock using SmartSwitch emergency recovery. Still no fixes.
Please help my phone cannot use cellular service!
Any idea Im all ears. I tried various methods for older Galaxys around the xda, none worked.
I know my IMEI and S/N how can I fix it.
Please help!!!!

With all do respect.... I don't think he was bashing anyone....he was just saying he flashed a ROM that wasn't posted to XDA...more than likely there wasn't any other option to ask for help elsewhere since XDA is very helpful with responses from developers and others.

I was wondering if anyone that is overseas (outside america) could share an EFI backup partition with me so I can fix my phone. Maybe that would fix.

keep watching the echorom thread someone else had the issue as well.

I cant they banned me from seeing their forum when I reported the bug.

O I see. If something gets posted that might help I'll let you know. But 1 thing I saw already is trying to flash multiple times with Odin
It might not work the first time. Or the second... or the third. Try like 10 times in the mean time until someone can help. If all else fails there has to be a way to make a working imei again since you know it anyway

write stock rom

This happened to me before in a old Tmobile S3 (T999) I had only edge network...
It was a headache and I was only able to put it back working going to a store that had BOX for flashing and do it myself with their box
and rewrite my IMEI manually during flash, as they were not able to do it (more say didn't have patience) .
I dunno if there is a easier way to do it... but this was how I fixed mine back then. But one thing is true, I lost a lot of time back then trying to fix it and if it happens me now again I would do a quick search and if not quick solution, try to find a guy that owns a box as it will literally save you days and sleep. However there are excellent devs around so they might be able to help..

Would u have any suggestions on where I could go to fix?

Quick question. What csc is in your phone now? Have to tried changing it again with a new one or the one that was originally on it when you got it? Like a flashable zip? Cos it looks like somehow the one you used must corrupt something in the efs... which is bizzare

I went to local store that usually unlocks/fixes phones, but I had a friend connection around.. hence they allowed me to go inside and do it myself.
Try to search 1st around if there is a solution, as it might be... I can't remember how it happened to my phone, but I was flashing lots of ROM without a problem and then it happened for some reason. There is a reason for it, however I couldn't find it as my knowledge is limited. I do remember that I tried, stock, odin, kies, whatever... and nothing worked until I went to try with a BOX.
IF you can't find a quick solution try to search around physical stores that flash phones, as they usually have a BOX and probably they might pull the S7 image already for their box... try to search a friendly one and take the purchase papers with you as most are not very comfortable with anything that might involve IMEI if you odn't know anybody.

Quick question. What csc is in your phone now? Have to tried changing it again with a new one or the one that was originally on it when you got it? Like a flashable zip? Cos it looks like somehow the one you used must corrupt something in the efs... which is bizzare

It was the German based CSC
G935FDBT1APC5
However I flashed back STOCK which has
G935FNZC1APAX
The bizzare thing is my phone appears to still get a signal, but emergency calls only. When I #06# It shows 00000000000000 for 2 MEIDs. Which is weird as I don't have a dual sim model. This is even after Odin stock, no root.

I went to local store that usually unlocks/fixes phones, but I had a friend connection around.. hence they allowed me to go inside and do it myself.

Fair enough, I still have the original purchase, I got it from overseas, receipt, and sticker still on the phone. Even the box. at the same time i was wondering if anyone overseas, (not in the usa) would be willing to backup EFS and PM me with a G935F because I could use that meid in the usa. I have no intentions of going overseas to Europe anytime soon but I might go abroad if its oceana or Asia.

Galaxy S7 Flat -- no signals after flashing Rom? Plz help

Hello guys,
I've started to freak out a bit now as I can't get no signal on my S7 ( GM-930P) whatsoever.
I had my phone running ok ( living outside of USA ) everything seemed fine.
Flashed the GM-930V firmware to jump on the Nougat beta ( everything worked fine n sweet )
Wanted to try the Custom roms ( Eco signals worked fine ) experienced FC and insane batt drain
Tried the Stangfire customrom v2 ( signals worked fine ) experienced a weird UI glitch after rebooting
decided to go back to the Nougat beta as it felt a lot stable and the batt life was great
Now that's where things go south for me. I had no signals at all and my sim card doesnt seems to be recognized at all
i tried all sort of things after that. flashing back to sprint firmware / verizon / nougat beta / custom roms all works fine except i have no signals whatsoever trying diff roms on the signal bars it either shows a " X " or a " Circle with a line through it "
when i try to perform any dial codes in the dialer it doesn't seems to work either eg" *#06# " it doesn't brings up the imei window it just stays there and when i hit the call button it pops up " Mobile Network no Available "
it must have something to do with the baseband or the radio maybe? can someone pls help me with this ?

anyone

Have you tried going back to a stock sprint firmware?
Sent from my SM-G930U using XDA-Developers mobile app

Yes I have jumped back to every single firmware stock ( sprint, verizon, the G930U ) Nougat beta, Custom roms everything works except the call service i get a cross over the signal bars and the moment i insert a sim ( tried 2 diff carriers ) i get the " invalid sim " error msg pop up.
Am not living in USA and i have bought this phone locally it was working fine. I can't reactivate it with a Sprint sim for obvious reasons as am not in USA

Well seeing as how you bought a sprint version s7 there's a simple answer being you f***** up. It's a locked bootloader. Have you done no research before attempting to do any mods to this phone? I have nonsolution for you but I wanted to. Comment on how your stupidity ****ed your phone up. You're the problem with society. Oh cool new phone I'm gonna do a bunch of.stuff and make it awesome etc and then you **** it up and ***** and moan looking for someone to fix your mistake. If you had any common sense you would have done some research first. I hope your phone doesn't work ever again.

well first of all thanks for taking time and reading through but dude am not the reason why he/she left u lolx chill. I actually did flash the phone on diff firmwares quite successfully from Sprint to verizon to the G930U even did the Verizon to Nougat beta update from there got back to sprint and then installed a Eco custom rom. So for u saying u can't flash ( don't know what u mean by mod ) this phoen i think u need to grow some balls and try. It actually works has nothing to do with a locked bootloader i wasn't trying to flash a custom recovery. I did somehow get it into a locked state somehow i agree but not cuz am so stupid not to read through ( if u use your common sense what u advised to me ) many of the posts and threads actually say this and this firmware for this and this variant of the phone.
Chill bro and am sorry if u got your phone f**** up the same way. It would have been an easy fix if i was living in the US just plug yr sprint sim in activate and u are back in business. In my case i can't do that but i can still get it back working if i pay a certain amount i just was just trying to see what chances i have got to get it back accept my sim without paying so am really sorry to let u know my phone would get back fixed

Show me this research he was suppose to find saying he'd lose call capabilities once he switched to different fw on his sprint s7 using an international service provider... Root research is limited on this device if no one tries anything new there will be no development on the device. You want to be scared and keep ur device not "awesome" fine but don't put down someone cause they asked for help.

Exactly there is always going to be someone to test the waters so for others it's clear not to do the wrongs we did and that's how it works . I still am not sure what triggered it cuz i did try out every single firmware and the 2 custom roms " Eco and Stang5liter " as far as i can remember I flashed Stang5liter custom rom and i was on the G930U firmware ( i think that rom was meant for Verizon firmware )
Rom Version:
G935VVRU2APEI[/COLOR]
Model number
G930V
Android security patch level
August 1 2016
Baseband Version
G930UUEU4API3
i think this is what caused the phone to go back to it's locked status as the baseband didn't match/was more updated than the Rom build ( totally my mistake ) maybe something ppl should be paying attention when flashing to a custom rom

what do u think made yr phone get back in lost status? were u just flashing a diff stock firmware or a custom rom? Me too had to pay and get it unlocked. Lucky u i had to pay approx 22$ USD in my local currency to get it back unlocked and working
