Hello. The site mentions the sprint V20 yet the hidden menue does not have the tutorial selections. I did the g5 no issues but the v20 is different.


Yeah but is your V20 updated? If so that's why. Read above posts. Only way is buy a remote unlock.

I paid for an unlock service for my LG LS997 in which GCprokey was used.
The phone was unlocked for a while until I restarted.
It got locked and it is now showing SERVICE DISABLED.

Is there a fix for that.

Under network settings is it set to GSM/WCMDA/LTE?

You need to use a Sprint SIM or an AT&T SIM or something like that. It's the specific SIMs that you are using they are blocking the option. It's because of the country code of the SIM.

I can't access the *#*#4636#*#* hidden menu. The phone does this and after some time returns error.


To get rid of the activation you need to ##RTN# and use the SPC code to factory reset it. (Not sure if that affects remote unlock though)

I have done it and yes.I lost the remote unlock(it now shows invalid sim). Guess I have to look for a reliable permanent unlock for the phone.
Anyone who has successfully gotten his LG LS997 unlocked?

I was able to get my SPC though this thread. Worked like magic

The only unlock available is remote unlock. Contact who you bought it from and say it’s relocked itself.
