1. Vivint Sky Installer Code
2. Vivint Go Control Installer Code

Hi – I just moved in to a new house and the previous tenants said they had never used the system in 4years so I don't have a code or master code – how can I reset. Vivint installer code is 2203. Free rainbow. Then update firmware. (If the installer code doesn't work/has been changed. 2GIG DIY Admin. Announcements, and FAQ.

All, I recently got a Visonic PowerMax Complete system installed via an authorised installer. After installation, he changed the user code to the code I wanted. I have been using the keyfobs to arm/disarm the system and never used the user code since the installation.

Recently, I wanted to add a new keyfob and you require the user code to do this. The problem is I can't remember the code. I have tried all possible combination without luck.

I might be able to get the installer code from the guy who installed this. He can't remember what the user code was.

Is there any way I can reset the user code using the key fob or installer code? The guy wants to charge £70 to come out and reset these codes. Any help would be greatly appreciated. Cheers, Vish.

I purchased a house that came with a Vivint-provided security system. The hardware includes a 2gig Go!Control panel, and a few sensors on the doors & windows around the house - and a couple sensors that the control panel remembers but no longer exist. I have to bypass these missing sensors every time I arm the system. I would like to have the option to re-program the Go!Control to permanently forget these missing sensors, but I'm unable to do that until I manage to reset Q44 to 0, removing the installer lockout. I've seen some threads on this forum and elsewhere on the Internet that talk about buying a replacement GSM module, swapping it out, subscribing to another security company, having them remotely reset Q44, etc. I am trying to avoid that if possible. I already purchased the 'firmware update cable' and successfully updated the firmware on the device to 1.10.1.

This process revealed to me that the cable being used is really just a USB 4 pin serial cable. I've discovered that you can use a terminal program (I use PuTTY) to open a connection to the Go!Control device at 19200 baud through this cable and see lots of debug output during the device's bootup and operation. It's fairly interesting to see. I haven't seen evidence of anyone else having experimented with this serial connection yet, but I admittedly haven't looked particularly hard. Does anyone else have experience with this? What I am hoping to be able to do is to use this established serial connection to write a new settings configuration to the device. So far, I haven't found a way to write anything it.

I suspect it is possible, though, as the Go!Control's manual references a 'PC Downloader Software' as being able to reset Q44. Since the firmware update clearly happens over the serial connection, I would assume this PC Downloader Software does as well. Speaking of which, where is this elusive PC Downloader Software? The only link I could find for it anywhere pointed to a thread on this forum that apparently no longer exists. Thanks in advance.

Watchd0gg: We should get in touch. As of right now, my progress has halted.

I learned just enough during this process to be dangerous, and I seem to have bricked the control panel. I ended up just purchasing another unbranded & unlocked panel which satisfies my home security needs, but I would still love to resume this project if possible. Learning is fun. I've not yet made a blog, but I can summarize what happened here. It turns out there are two ways to connect to the device via serial.

One is as I described above at 19200 baud, which gives you a bunch of real-time debug info about the device and appears to be read-only. The other way is right as the device is powering on, at 115200 baud. This is the method the firmware update utility uses, which obviously has write access. I sniffed the entire serial conversation between my computer and the device during a firmware update, was able to reverse engineer the protocol on a very basic level, and wrote a unix shell script to send multi-byte commands to the panel.

At this point, I began (carelessly) experimenting by sending random commands 1-byte commands to the device to see how it would respond. After a few experiments, it stopped responding. I can only assume that the last successful command I sent to it meant 'Here's a new firmware', I subsequently sent it garbage, and the bootloader is now defunct. The device no longer lights up, makes noise, produces any serial traffic, or does anything else I've noticed to indicate that it's alive when supplied with power.

Maybe it's possible the device could be resurrected through JTAG with a valid firmware image. This is something I don't have experience with, though, so I could also very well be SOL.Zombie thread rises from the grave. Checking back in with great news.

With ongoing significant help and tutoring from watchd0gg over the past several months, I have successfully repaired my Go!Control panel to working condition. It is a very involved process but also very powerful, and I am confident that the methods I used could be used by others to forcefully reset Q43 and Q44 on their Go!Control panels to regain full access over their system. Depending on how much interest there is, I might consider putting effort into making an easy-to-use software tool to facilitate exactly this. It might also be feasible to do more in-depth things like replacing the stock sounds & images used by the device, adding or replacing vocabulary words for programming purposes, etc.
