[Q] Unlocked 2.1, is this lost when upgrading to 2.2? - Captivate General

I havent really been able to find a definitive answer here.
If you have stock 2.1 unlocked, will it remain unlocked after a flash to froyo 2.2? Reason is i have a captivate unlocked on 2.1. for use here in Telecom New Zealand as we have an 850 3G network. I'm worried the phone may relock after an upgrade to 2.2 and I wont be able to unlock it again on 2.2.
Also, which 2.2 rom has HSUPA included? Just starting my captivate upgrade experience and from what i've seen so far, the hsupa needs to be flashed separately in odin or similar? Be best to flash an all inclusive romas I dont think Im confident yet to be flashing separate kernels etc via Odin yet... Been flashing windows mobile roms for years but this is all new territory for me with Android!
Thanks in advance for any assistance provided.

Any of the i9000 based ROMs ( mine included) gave HSUPA.
Sent from my Captivate

Cheers Mike, looking forward to running your ROM first
Anyone else with an idea of unlocked 2.1 remaining unlocked after flashing to froyo 2.2?
I suppose worst case scenario, it relocks, then i can use clockwork recovery to flash my backup.

I've had mine relock but it's not a big deal if you have your unlock code saved...Just re-enter it and it will work...

Yeah it's the same unlock code no matter what software version you're on.

cheers for the reply everyone.

Some of the above info is not 100% accurate - you can lose unlock and be in a state where the unlock code does NOT work.
Back up your /EFS partition (making sure to get the nv_data.bin and md5 files). Somehow the encrypted nv_data.bin (new roms) gets changed so it has no unlock code to validate against. If this happens, the old unlock code doesn't work.
If you save the files in your /efs partition, then you are always good.

mine did not relock when i upgraded.

Cheers for that, will definitely backup my efs folder to make sure.

Mine didn't relock after the upgrade either

just flash back to jf6 and get your unlock code. Keep it somewhere safe and if you ever need it again you have it at your disposal.

I tried that also but the 1.0 version says I am missing the file.
The file the unlock tool is looking for has been moved and encrypted when you install the new Froyo ROM. Even if you flash back to 2.1 ROMs, you won't have that file back. I read that somewhere there is a thread in dev section to help you recover from that but it will be very difficult thing to do because this file is not part of the firmware (each phone has a different file/unlock code).
What you should have done is unlock first in 2.1, save the unlock code somewhere and flash to Froyo firmware. The unlock code for your phone will never chang (based on your phone's IMEI number).
Right now I am kicking myself I didnt save the unlock code somewhere =(

[Q] Unlock Code

I'm Just wondering If I update to 2.2 will my phone lock again or once it's unlocked it's always stay unlocked even if i do a hard reset >?
I haven't updated to 2.2 yet so don't take my word, but I've read that it re-locks and disables the easy way to find the unlock code.
But, if you write down your unlock code before updating to 2.2 and then enter it again in 2.2 you're good to go
Definitely save your unlock code somewhere so that you can re-use it if it re-locks. My phone has gone through JH7 update then Froyo update and stayed unlocked. But others do claim theirs get locked again.
Regardless, your unlock code should be the same because it is sololy based on you IMEI number.
so, is the general consensus that once you're on JH7 you can no longer get the unlock code? or did i miss the 'how to' thread for that?

JH7 is still 2.1 ROM and it is still possible to get the unlock code (a little bit more efforts than stock JF6). 2.2 ROMs are impossible to get unlock code as far as I know.
The following is pure speculation---feel free to object
It *may* be the case that, once the official Froyo update is rolled out, an unocked phone will stay unlocked. I assume that somewhere in the internal file system is a file that keeps track of the network lock status of the phone. The unofficial JI6 ROM may have been an image or backup taken from a locked phone; in this case it makes sense that the network lock will be restored upon flashing that image. But, in an official update, this may be avoided.
On the other hand, I have seen posts mentioning that not only was the phone relocked upon flashing JI6---the old unlock code itself was apparently rejected! I find this both puzzling and worrisome: I do want to upgrade to Froyo when the official update arrives, but I also need my phone to stay unlocked.
BTW, I updated to JH7 OTA and the phone stayed unlocked.

Ive got no issues with a little more effort – just not quite sure how to go about it. Would you be good enough to either fill me in or direct me to a thread where i can figure it out?
Thanks!
I have flashed my phone a few times - JH7, JI6 (2.2); and now back to stock with JH7.
My phone is locked and the original lock code dos not work.
According to a post on Cyanogen's forum - I can take the existing stuff in BML3 file:
SSNV´'šù..Jøý.—.~n.•öVÚðÜž|.hÿ6*§ÒùF....Gmñ.¾E.¸Øoß’.Öµ.†.ˆì..Á.ñ-*y!96Ý.FFFFFFFF........................00100100101#31015031017031118031041031098099999#
And replace the FFFFFFFF with my 8 digit unlock code and push this file back to the phone.
Has anyone tried this?

My phone stays unlocked even after JI6 flashing. I have no idea why others get locked again. Maybe they never unlocked properly when they were still using 2.1 ROM.

i had this problem with 2.1 rooted when i put in my non att sim card, asked me for the unlock code again, go to this to get it unlocked the msg above
i updated my firmware to 2.2 froyo rooted thanks to senior member last night and it never asked for the unlock code ever again
Save your unlock code!
Every time I've flashed a new ROM I've had to re-unlock the phone. Supposedly other people have not had to re-unlock, so it sounds like a case of YMMV.
I had my phone unlocked and working fine overseas. Got back could not wait so put froyo on. I thought the unlock would stay it did not. But i had the codes so no worry. I tried twice the codes from before but they did not take. So going to get a cheap tmob prepay sim and try that did not want to kill my other good sim. I will let you know how that works. If any one has any ideas please let me know.
Edit: got brave put it the sim from Japan again after flashing cog beta 4 and did not ask for unlock code. So i guess it works,somehow. Ill still get the tmob sim tomorrow and try. But looks good now.

[Q] Get unlock code for unlocked captivate, but no original nv_data.bin available

Hi Guys,
I got this unlocked Samsung Captivate phone from CL. Works fine. But I was wondering, since the original nv_data.bin is no longer available, is there a way to know what is the unlock code ???
The guy from whom I purchased the phone does not respond to my emails.
Since there are cases that updating to higher Versions might ask for unlock code once again, I am just being well prepared for the worst.
Thanks
luv2rip
Yeah me too
Yeah me too!
As long as you stick to the ROM that was originated from Captivate ROMs, you should be fine. Most of those get screwed up and need re-apply unlock code are from flashing those European ROMs tweaked for Captivate.
Also, I read there is now a way to extract unlock code even in Froyo 2.2. I'm pretty sure Dev section has a thread about it.

Just got a Droid 2 Global, unlocked, can't update, custom ROM help would be aprciatd.

Hello all
I purchased a Droid 2 Gloabal unlocked on eBay, got it today, thankfully everything works (well atleast for now).
Currently it's running 2.2 Froyo.
I was prompted to download the OTA software (GB), and I did. The phone then asked me to reboot, and install it, I hit okay.
The next thing is the update progress bar, all goes well, and then all of the sudden, I get a little exclamation mark on the screen, and it reboots.
Now, for some reason I have CW Recovery Mod alway running at startup, never encountered this before om another phone (non Droid, this is my first 'verizon' droid).
Oh, I live in Canada and use Virgin mobile.
Anyway, I select "reboot phone", and then it goes back into 2.2 Froyo, tells me that "Update failed".
I was looking at different roms, just can't figure out which one is the best for my setup - Canada.
The phone looks like it's rooted, I also have the Droid 2 Bootstrapper on it, however the tool gives me an error no matter what button I press in it.
Can someone point me in the right direction please
I am somewhat of a noob.
Also, does nandroid backup the whole system, kernel and all, if things go belly up, will it always fix my issue?
Thanks!
----------------EDIT----------------
So, I found out that the phone is actually not rooted, so I rooted it, using Z4root.
Now, I am at a loss. The phone that I flashed before was quite straightforward to do, this one is stragne.
As mentioned above, I can't upgrade to 2.3 since the phone is rooted (also, I renamed blurupdater.apk so now I don't get the pesky warning message to update).
What do I do to go to 2.3.x?
Since, from what I read on the forums, you can't go 2.2 -> custom rom 2.3, you have to go 2.2 -> 2.3 official rom -> 2.3 custom rom?
Any ideas?
Gingerbread Full SBF 4.5.608
http://forum.xda-developers.com/showthread.php?goto=newpost&t=1437177
Thanks for that link.
So, I can flash that over my current install of Foryo + root + Clockwork?
Also, what about the unlocked status of the phone?
I have no idea how it is unlocked (perhapps a rom that does not honor provider locks?), is there any way I can tell if the phone has been truly unlocked?
If I go to the menu to enter the unlock code (I forget what menu it is, but you get to it by dialing some number), the "Enter unlock code" still pops up?
What could this mean?
I don't want to brick my phone xD
Thanks again!

Yes you can flash it with what ever you have or don't have
You will have to reroot after with petes root tools
Once unlocked the phone is always unlocked can't be locked again
Sbfs and roms don't touch that part of phone
Sent from my DROID2 GLOBAL using xda premium
Thanks, and lastly, about Clockwork Recovery, will it need to be reinstalled as well?
Consider reading this: http://droid.koumakan.jp/wiki/SBF
The intro part should probably provide the answer to your question.

Yes, you will need to reroot and then flash CWM.
Hello again all!
Finally got the time to try to SBF the D2G to Gingerbread.
One question still lingers in my mind.
The phone was sold to me as unlocked, and for all intents and purposes, it is. I use my Virgin mobile SIM, and it works.
However, here is my concern. Is there only 1 way to unlock the phone? A code unlock?
Why I am wondering, it's because if you enter "#073887*" the code entry dialog still appears. Is that supposed to happen?
My fear is, that once I SBF from Froyo to GB, my phone will be locked (unless it was really code unlocked).
So, my question is twofold:
a) would entering "#073887*" ALWAYS show the code entry dialog, even if the phone has been unlocked?
b) Is there a way to determine if the phone has been code-unlocked, v.s. some sort of custom/moded rom that does not honour the provider lock?
Thanks!
Yes, the code input dialogue is displayed no matter what state the phone is in in terms of SIM lock.
There is no ROM or software tool that can avoid the SIM lock on a DROID2 GLOBAL device.
If the phone is unlocked, it stays that way. With a locked phone, all you can do to use it on GSM (besides unlocking normally) is use a TurboSIM. If you can use non-VZW/VodafoneNL SIM cards, your phone is unlocked.
You cannot enter unlock codes while on custom firmware; only stock ROM supports unlocking.
Flashing does not reset the SIM lock status. An unlocked phone stays unlocked even after flashing an SBF image.
you should add that to your wiki, good info
Thanks, that's great info!
I will SBF the phone later and let you guys know

Will Gsm unlock remian intact after upgrade to ICS?

so I am using ATT Skyrocket outside USA. The previous owner somehow unlocked it and then sold it to me. The phone is currently running on Gingerbread and I am planning an upgrade to ICS (i know how to do this). What I want to know is that after upgrade will the sim lock be reverted or my phone will remain sim unlocked after update?
please consider that it will be difficult for me to buy an unlock code so please answer only if u have tried or some expert knowledge.
thank you
I had my phone unlocked by kachman from this forum by a usb hack as he clamined. It stays unlocked no matter what rom you flash or upgrade. Also from cellunlocker.net, they claim if you unlock your phone using their code, you phone will stay unlocked regardless of what system you flash. It's hard to say if your phone will remain unlocked given the little info you provided. I'd say just stick with gb until you could get it unlocked again if you need to.
Your phone SHOULD remain unlocked. An OS upgrade should not affect that, or else everyone who gets their phone unlocked would have to bring it in/get a new code every time they did an upgrade, which doesn't make much sense. I Mean I can't say this with 100% certainty but I'd be a considerable amount of money that this is the case.
unlocking is permanent ....

will there were four parties involved in the middle before i got hold of the phone but when it came to me it was already unlocked and ready to take in any sim...now the point is that since its unlocked is it possible to find out how was it actually unlocked? and if it was done through an unlock code, is it possible to extract it from the phone itself? (some one has already payed for unlocking it so now there seems to be no point of keeping the unlock code in a secret location)

is there any proof of what you say? -- The unlock code and unlock state are stored in an encrypted file system partition (mmcblk0p18) that is accessible only by the radio and completely separate from the kernel, radio, system, data, and cache partitions that are typically overwritten during a ROM install/upgrade. So, yes a SIM unlock is permanent.
