*false alarm* losing unlock if you factory-reset your DoCoMo phone?

[patrixl]

Or I guess not, I should know better than just believe random posts on any social network :P *hangs head in shame*

Im not sure, I've usually never master resetted the phone and just manually deleted everything on my docomos...I would hope not lol,

I'm guessing if it was SW unlocked it might lock back up. Who wants to try??? Not I says Sam.

[Jphoner]

If you mean Privasy/Factory reset so it's ok.
No lock back. Can be reseted so many times as you wish.

Assuming you're talking about a factory unlocked post 2011 docomo device, then no, you won't lose your unlock. I did a factory data reset a number of times on my SH-12C and it was never relocked. Remember, the factory data reset option in Android doesn't touch the OS, it only clears the users' data.

Not sure about soft unlocked devices like older Samsungs and older Toshibas though.

I didn't mean anything except that I posted before coming to my senses that I read this "fact" on a social network without checking or thinking beforehand... ie I did a factory reset myself on my own SH-13C some time after unlocking it, IIRC......

Hence the whole false alarm in the topic title

Yes, I just wanted to clarify

Also, the post where I got that info from, I guess it was dealing with a Galaxy Nexus. So things may be a bit different with that phone compared to the Japan-made Androids.

But is it true (factory resetting a docomo GN result in losing the unlock)?

Different filesystems for different phones so even if it were true for the GN I'd be surprised if it carried over to other devices.

[patrixl]

Apparently the unlock info for the Japanese GN is stored in /data, meaning a reset will wipe the unlock too.

Doesn't apply to other Japanese handsets afaik. Their unlock process is different too.

then how about saving the unlock information from /data on your SD card, then when you factory reset/wipe the phone just copy the content from the SD to /data in the phone, reboot and theoretically you should get unlock again?? oh well seems like too easy to be true haha (of course if we are talking about an Android keitai)

[patrixl]

Yup for the Galaxy Nexus, seems that a backup and restore of /data should be enough to restore the lock. Doesn't apply to other Android phones on DoCoMo though. And you still need to unlock it the first time, with a code (obtained from DoCoMo) generated from the IMEI.

I wonder if an online-purchased code will work, like it did for other international ports (HTC, etc) for SoftBank.

Supposedly works for the Nexus, not for the Galaxy S2 or any other docomo phones.

I've reset and tested pretty much every Docomo model released after April 2011, and the only one that relocked was the Nexus.
