Please, how can I get the marshmallow rom for Axon 7 Mini B2017? I upgraded to 7.1.1 and would like to downgrade to 6.0.1. Will this firmware work for the B2017 model?
Renaming the file to update.pdf did not for me, unzipping result in a directory containing a update.zip file.
I’ve tried both files using this file both worked fine but after update process android version is stil 6.0.1.
The B12 release is exactly the same as I received in march or april as OTA file. I live in the Netherlands and still no 7.1.1 version
It is still in marshmallow.Hopefully, the device gets the nougat update soon.We will post an updated guide as soon as the official nougat releases
I’m haven’t suceeded yet installing the update. Despite all the good advice. I’m also from the netherlands. Coinsidence?
B.
Neither method is working for me 🙁 In the first method, even though the zip file is on my SD card, my update manager only says that my system is up to date and I can’t look at anything on my SD card even though it says it will look at the card. In the second method when I get to the recovery mode step it says, “Sorry, you can’t sdcard upgrade”
Enable developer option, OEM unlocking and usb debugging
Got to another stage! However it’s still not working, there’s an error. After it is verifying the update package, it says, “E: footer is wrong” and, “E: Signature verification failed”, then “E:error: 21”, and finally “installation aborted.”
Please help!! So close!
