  1. Old OTA link is for a Z812 not the Z831.. You may want to fix that. Will await new Z831 OTA zip file..Thanks very much.

  2. Looks like people are now finding out about this new nougat firmware for the maven2. Many of us use the phone but don’t use att for service so we are unable to get the nougat ota. This manual download will come in handy… Will be looking for the download link. A few folks on xda been looking…Thanks

  3. Again, this link is to a 168Mb file. The firmware update you are advertising was a 1.4Gb OTA file. Are you just looking for clicks? When you say the link is “broken” , what exactly happened? You added a link again, why not just tell people you never had the file? YOU ARE A JOKE? How do you say fraud in hindi or paki??

  4. Where I can find this firmware’s ?
