JH7 update removes unlock code

This has been observed in at least one post, buried deep within another thread, but I thought it is important enough to have its own thread.
The latest JH7 OTA update seems to remove the file containing the unlock code for the Captivate. I unlocked my phone a couple of weeks ago, and after receiving the upgrade I verified that the phone is still unlocked. However, the SGS Unlock app no longer finds the code. Presumably, other PC/Mac-basede unlock techniques will be affected, as they look for the unlock code in the same file.
Anybody else can confirm this? In a word (two, really), what now? I was about to buy another Captivate for my wife, but the only reason she was willing to get it instead of the iPhone 4 was the possibility to unlock it (we travel to Europe twice a year).

If I manually peek at the bml3 or nv_data files, I still see my unlock code after JH7. I haven't used any apps to unlock, but it sounds like they just need an update if they are failing.

Well, if you bought the phone today, it wouldn't have the JH7 update, I would presume. So, you can run the unlocker to get the code. It sounds like, though I cannot confirm because the update failed on my phone, that it just deletes a file with a number in it. If that's the case, it shouldn't be able to undo any existing unlocks, and there's no time limit once you have the code.

Then you better buy one now and extract the unlock code before you upgrade. It typically takes AT&T a few months to sell phones with new firmware.
Even though new firm ware makes current unlock method useless, it won't chang your unlock code.

Ok, so maybe the SGS unlock app fails but could be fixed in the future, or perhaps one of the other methods still works...

One question: are you rooted? I tried copying the nv_... file to the sd card using adb, but got a "permission denied" error.

Yup. That may be what is breaking the apps... I don't remember it needing it before to access /efs/nv_data.bin. I can read it after su though.
edit: If you want to try and get it manually, the following grep works for me, but I'm not exactly sure if it work on others...
su
busybox grep -E "^[0-9]{8}$" /efs/nv_data.bin
You should see 2 identical sets of numbers.

OK, so this is very good news.
To clarify (here's the noob asking...): rooting does *not* affect your ability to get the update, right? If all rooting does is install su & friends (and uninstall removes them), there should be no adverse consequences at all, especially if you unroot prior to getting the update. I'm just worried about the reports of updates failing (everything went smoothly for me, but I'm 100% stock and not rooted). Thanks!

I am rooted and the install went fine for me. I had not done any of the lag fixes, overclocking, or flashing custom ROMs though.

Same. Rooted before the update. It even stayed rooted after the update.
If the grep above doesn't work btw, look here for how to manually copy the files to your computer, and view the code using a hex editor: http://forum.xda-developers.com/showthread.php?t=761045 . Just remember you need to use "su" first now. Or just wait... One of the devs will probably update their app soon enough.

Ok, thanks! This helps a lot.

I reflash back to stock rom JF6 from JH7.
it seems like flashing back to stock rom JF6 wont restore the unlock code!

Posted it in the previous page. The files are still there for me in JH7, it's just that nv_data requires root access now.

It could just that the servers are currently overloaded... take a look at the thread on successful updates; although there are still only a few reports, phones that did not have a lagfix at the time of the update did OK, and rooting does not seem to matter. In any case, it's not like your update failed: you haven't even downloaded it yet.

That makes sense, because the JH7 update changed the *permissions* of the nv_data file. So, even if you reflash the stock ROM, the permissions on that file stay the same.
BTW, I suppose this means that one way to fix this would be to create a very simple update.zip that changes the permissions on that particular file. Although, if you go down that route, you might as well root your phone, I guess!

thx for post !

Try the following command over adb:
Code:
adb reboot bootloader
(or in terminal emulator on the phone itself, removing the "adb" part of the command).
From there, you should be able to see if your bootloader is locked. Maybe there is a custom recovery out there somewhere for your phone, which you could possibly flash if your bootloader is unlocked. From there you should be able to flash a custom ZIP to root the phone.

Well, I'm afraid I'm out of ideas then. Is there an earlier version of Android available for the phone? If so, anyway of downgrading to it and rooting there?

well thanks m8 for ideas But the first try I made was downgrading it to 2.3.5, I find the tutorial on some chinese forum... but PHONE freeze and I get a new one over the warranty
WHERE IS MY HERO WITH THE SOLUTION !! WHEREEEE pleaseeeee Im crying here ;(

Is it simlocked by a provider?
I had a GT540 once, and google removed stuff from hidden menu, and permissions needed to root.
So I know this problem, and I didn't manage to solve it.

Help, deleted nv_data.bin

I was helping a friend to unlock his phone, and I accidentally delete nv_data.bin and dont have a backup. I know the original imei, is therea way to regenerate the imei? If I dont have backup. Please if somebody know i need help

Try one clicking back to stock

ok, i will download in my house, but, i was reading that one clicking dont touch the efs partition, and that file was there

Was the phone on gingerbread or ICS/JB? If it wasn't on gingerbread (Assuming it was a rom not based on CM7) you'll be able to restore the files by using a one click

the rom is in 2.2.1. Thats ok? I download T959VUVKJ6_STOCK-UVKJ6-One-Click.
So, if I use it, this will restore the nv_data.bin? I ask before doing anything because i have fear of make the this worse

Yes it will. Keep in mind that it will also factory reset your phone

I do it and gave me a imei thats only 000000000000000.
I insert the sim and work, But, this will give problems in the future?

No it won't. lol The OP is already on a BML partition structure. That trick only works if you loose it switching over to MTD.
Sorry OP your IMEI is gone and short of some fancy hex editing their is no way to get it back. Your phone will still work with zeros but data might be an issue. If you wanna try the hex edit way look in the dev thread for OLD unlock threads. Good luck.

So, i will have issue with 3g data or something like that?
I see a way that i can input the imei with a z3x box i think, and in my city there is someone with that box, that can work?
i search and only found: ;
REF] How to unlock SGS 4G or Vibrant 4G (IMEI Problems fixed)[Updated 11-19-11]

I search in the dev forum. Do you remember something more about that post to search? :/

[Q] How can I make my phone run less sluggishly?

Hey
I have HTC desire s, which is pretty old (i'v had about three years now). In recent months it has started to run more and more sluggishly. After I re-downloaded a game that I played when I first got the phone I realized that my phone had experienced some power-loss, as the game that used to run smoothly now lagged. It wasn't so big deal as I do not play games with my phone so often, but now it feels like apps that I use and pretty much need like whatsapp and internet browser are also starting to lag more.
So now I am trying to find some way to restore my phone do the state it was when I first got it.
I have done almost everything that you can do with an un-rooted phone. (Ram,cache,apps...) I also did "factory reset" which actually seemed to help for a while, but soon the problem came back.
I tried also rooting my phone with super-one-click, but even I followed instructions "perfectly" and the app said my phone is rooted it actually wasn't.
I can try it again if it's necessary.

The toolkit provides steps to "Unlock bootloader" via HTCdev.com. You need it unlocked to root or flash a custom recovery.
PLS read exactly and keep in mind that unlocking the bootloader will reset your phone to stock. MAKE SURE you safe ALL your PERSONAL DATA before you proceed.

It toolkit fails (its important that you haven't change the folder name of the toolkit!)
We can do manually --> Go to HTC dev --> http://www.htcdev.com/bootloader/ select "All other supported models" you also will have to register.
and you need this adb/fastboot http://d-h.st/KIP

Hi, I had my S6 on android 5.0.2, carrier version, rooted and unlocked (with a imei which corresponded to a nokia after unlocking). The phone worked fine, I had service, I could make calls, etc... I decided to flash stock unbranded marshmallow on it, so I downloaded the firmware from sammobile and flashed it. Everything went right except I didnt have service (No service). I went desperate, I flashed modems, read thousands of threads, but nothing. Any suggestions?

When you flash your device you may loss your Imei number so you won't be getting service .but looks like you haven't lost it (provided you found them in the the settings option and not from the box which you got your phone from)
Look for a baseband fix for your phone in the site you got your ROM.
PS edit your previous post and delete your imei no.
I was just asking if it was there .

Ok, thanks alot. What would be a baseband fix?

Just a zip file of the baseband version that needs to flashed through recovery so the phone can get service
Edit: Your baseband version is OK as well.
Share the link where you got the rom pls .
Also try a normal reboot if you haven't tried it yet.
Update : you sure you can't make calls ,my marshmallow says no service(unless I haven't turned on cellular data) but I can make calls
.if nothing's working share the site which you got the rom from
