i have a linksys spa-2100. it was purchased in 2006 (marking indicates 2005 model). i was using it with Zingotel who is now defunct. they set a lock on the user and admin accounts with a unknown user/password combinations. i have tried all of the IVR and web based reset functions that i can find anywhere on the web and all require a password. since Zingotel is no longer even in business, their phone numbers are dead, their website is gone, etc., there is no way to obtain an unlock or password for it. Miracle Telecom has recently appeared and they claim to be able to use the Zingotel configured devices thus they clearly have the passwords. Miracle claims to have no connection with the former Zingotel, but this is clearly not true OR they have a proceedure to unlock any spa-2100. they would not be able to unlock these devices to use with their services unless they got the codes/passwords from Zingotel or have a method to unlock them.
many web discussions indicate that there is a firmware upgrade/abort during upgrade proceedure to unlock the device. i have also seen pictures of both sides of the board online. these indicate a JP1 which is a three pin jumper with a jumper in the pin 2-3 position. is this a method of hardware reset? i have no issues with opening the box as there are no seal marks, this device is my own, and the warranty is long out of date at any rate.
please advise. if responding, please also CC to my email as well.
