[Q] Unable to unlock captivate

I bought Captivate by paying all the equipment cost because AT&T told me that they will unlock it whenever I will have to go out of US. They did give me the code but it did not work. After 2 days when I called customer care and they said they dont have the code, but when I told them that I was given the unlock code 2 days back they asked me to spell out the code and then they said yes it is the code. I tried the code with the customer care but it did not work. Then I tried the method showed on youtube (generate_codes.bat, sgux.exe) but I get the
failed to copy '/efs/nv_data.bin' to './nv_data.bin': Permission denied
Error: unable to find file nv_data.bin>
Phone details: Firmware 2.1Update1
Baseband ver: I897UCJH7
Kernel 2.6.29
Build #: ECLAIR.UCJH7
I see my 550$ going waste Please HELP!
I have already tried 8 times and there are only 2 attempts left. Please help else I will lose all my money becaues I do not reside in US and I need to use this phone in my country.
Thanks

Have you done any ROM flashing?

if you haven't flashed any ROMs, here is what you can do. go to market then search for SGS unlock, install and run it, it'll give you the code. thats how i unlocked mine. write the both codes down just in case.

No I have done nothing. It is just 6 weeks old phone. Same as what was delivered by AT&T. I did not play around with anything (like rooting, or installing beta Froyo)

download SGS Unlock from the market, then run it. u'll get code.

I have already tried SGS Unlock. It says it did not find any codes.

try dial *2767*3855# the phone will hard reset, then try it again. i didnt have any problems unlocking my phone by using SGS unlock, have flashed some stock ROMs in the past few days and didnt have issue at all.

I think the JH7 update screwed up the easy retrieval of the unlock code.

There's some info about a possible work around in there, but the guy who came up with it is apparently French and the translation to English is a little rough.
and to the OP ... my code was all numeric, so not sure why you would have had to 'spell' it to the AT&T rep.

if you have not done anything on it, i'm assuning that you haven't rooted it yet. if thats the case, get z4root from market and root your phone. then use SGS unlock to get code, choose root-code option.

It is possible that your nv_data.bin is encrypted - the only way to know is to root the phone, and view it with a hex editor. If it is encrypted, there is a web tool posted in the dev section (search 2.2 unlock) that will take the nv_data.bin and rebuild it with whatever unlock code you want.

Did you upgrade to Update1 from AT&T? I did software update from phone and it updated the version 2.1 Update1.
I have tried it after doing the upgrade and SGS Unlocker is not working.

What does hard-reset mean? Does it mean "Restor to Factory Defaults"? If yes, I can do it through standard menu entry in settings? Is this different from the method you gave? Will hard-reset reset the 10-maximum-attempts-to-unlock counter?
Thanks for replying!

No. I have not done any ROM flashing.

hard reset = master clear on odin. it wipes out everything on your phone even SDcard. it is different to the standard menu factory rest. and i'm not sure if it'll reset the 10 max counter though.

Since there are only 2 attempts left for me to unlock Captivate, what will happen if I exhaust all 10 tries? I read somewhere that it will hard-lock or freeze. Can this hard-lock be reversed? Is freeze unlock code used to reset the counter?

If it does hard lock? Then you would need to take it to an AT&T shop.
Have you tried CLShortFuse's one-click root program? I haven't tried the Captivate unlock feature - but my guess is it should give you the unlock code.
You can get it here.

I have the same software on my phone as the OP. I got the phone unlocked by using the root method of SGS. Now how did I root the phone? Someone recommended the one click root method found inside the One Click Lag Fix found in the market.
So, to recap. I got the One Click Lag Fix app. Used the one click root method. Got the phone rooted (it is a couple of steps actually - you still have to update on recovery). Now that you have superuser status, used the SGS app to search unlock code using the rooted phone method. It will show the unlock code (mine had 8 numbers). Hope this helps.
PS: For anyone reading this, AT&T DOES NOT have the unlock codes yet. Any rep that promises that you will be getting an unlock code soon is not really telling the whole truth. All it shows on their side is that unlock codes unavailable but it does not shows when they will become available. I think I read somewhere that there is a 10 months exclusivity on the Captivate (starting when it first came to AT&T, which is this last July).

One more time - this is from experience:
If the nv_data.bin file is encrypted and unlock code doesn't work or can't be found you need to rebuild the nv_data.bin file. Period.
There are instructions in the Dev section under a thread titled 2.2 unlock.
If you use all 10 attempts - the phone needs to be sent to a service center to do a low level restore - usually Samsung not AT&T.

Help with restoring stock Android 6 from huawei p9

I have recently flashed one of the nougat Roms and would like to return to the stock from with Android 6.
My phone is a virgin contract phone(with optus boot screen) eva-l09 FCC ID qiseva-l09 I 6369a-eval09.
Can anyone tell me which stock from to get so that things like Android Pay work?

Australian Virgin phone btw

Pleaae, search in the forum, there are some threads about this...

I have searched,there is a thread with a heap of different stock firmwares but I'm unsure which one is right because I flashed the nougat Roms and now I'm unsure of the model number of the phone and I have no backup.
Presumably the model number in the nougat Roms info is wrong,maybe I have cross flashed?

Use the 136 full rom.
https://mega.nz/#!QE4TTSzJ!OjP6yXFtliK4XDRHLNIAKgxpf0gmhEeksDr_fjja0oY
1-. create folder "dload" in your external sdcard. Uncompress the rom zip inside it (one file "UPDATE.APP" and 2 folders: "dt" and "hw")
2-. turn off yout phone
3-. turn it pressing and holding power button + volume up + volume down
wait to restore.

Can you let me know if this works for you, nuttzo?
I've been trying to do the same as you for about a week now, with no progress

OK,ill have to find a different mirror for the file because that mega link seems to not work properly.
Through the phone I've tried downloading the file and both times the file is corrupted despite appearing to download fully.
On the raspberry pi the file stops once it hits 2gb and complains that the file is too big.

Thanks Iomunet but I can't download the file.
Mega sucks,i don't know why people use it.

Try installing mega app or from computer...

I only have a raspberry pi and the Android phone.
Mega sucks and doesn't work on both.
Unfortunately I don't have a Windows PC anymore.

OK I've managed to find another link to the stock ROM and have successfully downgraded back to marshmallow.
Android pay is still not working,any way to fix that?
Also Huawei id doesn't work,something about unable to service region.
Any way to fix these 2 issues?

OK it looks like if I install twrp after unlocking the bootloader I can flash the oeminfo IMG and remove the c900 build number from the phone.
That should get Android Pay working.
Now I have to pay for a bootloader code because I don't have Windows and I can't seem to get it through Huawei because their emails in chinglish are cryptic and the website links are broken.

You still have to unlock the bootloader to flash twrp don't you?
I have the Android and fastboot tools installed in Raspbian but I never checked the OEM unlock option in the developer options.
When I tried flashing twrp before it came up with an error something about unable to write due to permission error.
I assumed it was because the bootloader was locked.

you must unlock your bootloader first, yea. Huawei have a webpage to do it.

Haven't had success with getting to the Huawei page to unlock bootloader.
The closest I got to one I couldn't proceed because it required my mobile number but none of the country codes were from Australia so I couldn't get the SMS.
This is the email I got from Huawei which I couldn't make sense of.

You are a stand up guy/gal Iomunet,thanks for helping me.
Do I mark as solved or anything like that?

Just out of curiosity, how was nougat? Why did you switch back?

I will be using these directions to unlock, install TWRP, root!

Hope this will get the job done.

I do not love Magisk. Can I install TWRP and then SuperSu?

My phone is coming today. I want magisk because I want to use the app to customize.

Yes, that will work, TWRP is key here, magisk or SU is a preference. Grab the full ROM (1.4 GB) make a backup and you are good to go, you'll be able to recover no matter what you do.

Has anybody yet managed to unlock, install TWRP and flash EU rom? My device arrives tomorrow and this is the first thing I want to do.

I tried to unlock but I can't even unlock the phone. Maybe I'm an idiot but it's just too hard to follow this directions and there's also some Chinese involved.

I cant unlock the phone. I guess we need a CHINESE VPN To unlock it.

Seriously? I have unlocked several Xiaomi phones and never seen this. You definitely set up your Mi account and received approval for unlocking via sms?

I have my account all set up. I did not receive an an sms saying I can unlock it. I tried going through the process then I get the IPS error.

I just setup my account last night and received approval, and do not even have the phone yet. You should get an immediate verification SMS, and then a little bit later I got approved.

Don't know why I can't get it to work. I even downloaded turbo VPN to use a Chinese VPN to try to get the code and it would not work

Usually takes about 36 hours hours till you get unlock it through xiaomi.

FWIW,the vast majority of the original Mi MIX handsets that were sold by 3rd party vendors shipped with an unlocked bootloader,same w/the Mi Note2 Global version.
Have any of you checked for an unlocked bootloader?

Good question. Open the dialer, *#*#7378423#*#* should pop up a new system info window, you can verify in it.

...or just try to fastboot flash recovery twrp.img and see what happens.

i just got my mix 2 and had the same problem, use plexvpn and choose the shanghai gateway

Will try that when I get home. I actually got them to give me permission to unlock but now in the unlocking tool it says at 99 percent that the device is not associated with the account or something like that. I try to associate my account in developer options and I get a 10008 error. This is so brutal

That plexvpn did it with Shanghai location! Thank you. Now I will try and unlock and see what the next puzzle brings me!

This is crazy! Just had another problem. Tried to unlock by the unlock tool and now it says "Couldnt unlock. Binding time is too short. Less than 72 hours." UGH!!!! Any help would be appreciated!

You have to wait it out I'm afraid - I don't believe there is any shortcut. I had same issue with Mi 6 and it worked exactly after time had expired. You're nearly there...just a bit more patience!

Mobile frozen when turning on Bluetooth

Hi!! I hope this is the right place to ask this, it's been a while since the last time I visited xda and it changed a lot.
Almost every time I try to turn on the bluetooth on my phone, it freezes and I have to reboot it. Once it boots, the bluetooth works fine. Is there any solution for this without changing the ROM (I could do that, but I'd rather not tinker with roots and ROMs unless it's the only choice).
I have Android 7.0 and EMUI 5.1
Thanks!

You can try a factory reset. Maybe an app makes trouble.
If this doesn't work you can try to update - if there's no official update provided for you you can use DNS methods like FunkyHuawei or Firmware Finder - this will work without unlocking bootloader.
Of you can use my guide.
Problem with my guide is at the moment following: you need to unlock your bootloader. For this you need the unlock code but the page where you can get it is currently not available, so you have to pay for DC Phoenix or wait.

FunkyHuawei looks useful, but I'm not willing to pay 50 bucks for this issue hehe. I'll try FirmwareFinder if no other solution is proposed. Thanks for answering!

Same problem for me, but it seems fixed with oreo update.
