<ul></ul><p>Hello Pedro,</p>
<p>Can you let us know what the BCM4751 revision is for the Nexus 7 so we can add it here? <a class="external" href="https://redmine.replicant.us/projects/replicant/wiki/BCM4751#Devices">https://redmine.replicant.us/projects/replicant/wiki/BCM4751#Devices</a></p>
<p>Thanks!</p>

<ul></ul><p>Hello,</p>
<p>It's a BCM4751A2.</p>
<p>I'm trying to help out porting grouper to mainline linux in PostmarketOS and have adapted your base code (thank you :)) to get it to basically the same point as you have. Thanks to your previous work I have also found the offsets to extract the "patch" from the `glgps` binary that comes in the grouper official factory image. The patch is slightly different from the Galaxy S but the device seems to accept it.</p>
<p>When I finish cleaning up my code and upload it to my repo, I'll update this issue with the link. I hope this helps more people get interested into reverse engineering this device.</p>

<ul></ul><p>Pedro, not sure if this helps or not, but I found this on github: <a class="external" href="https://github.com/klusark/crespo-gps-utils/commit/eaa760baae4895826b7e0729296092f746b91f44">https://github.com/klusark/crespo-gps-utils/commit/eaa760baae4895826b7e0729296092f746b91f44</a></p>
