Upgrading B2G on the ZTE Open,

[Guest hecatae]

ZTE officially updated the ZTE Open to 1.1 and abandoned it.
 
To manually update it to the latest and greatest, follow these simple steps:
 
Grab a copy of Ubuntu 12.04, and install basic pre-requisites:
 
https://developer.mozilla.org/en-US/Firefox_OS/Firefox_OS_build_prerequisites
 

sudo apt-get update
sudo apt-get install autoconf2.13 bison bzip2 ccache curl flex gawk gcc g++ g++-multilib git ia32-libs lib32ncurses5-dev lib32z1-dev libgl1-mesa-dev libx11-dev make zip

 
Install adb, install java
 
clone the b2g repository:

git clone git://github.com/mozilla-b2g/B2G.git

 
grab a coffee
 

cd B2G

 
now if you want to build 1.3 run
 

BRANCH=v1.3 VARIANT=user ./config.sh inari

 
1.4
 

BRANCH=v1.4 VARIANT=user ./config.sh inari

 
2.0 < code complete as of 1st September 2014
 

BRANCH=v2.0 VARIANT=user ./config.sh inari

 
Wait for it to build.
 
when it finishes run

./build.sh gecko

 
This will build only gecko at the latest version
 
to flash run
 

./flash.sh gecko

 
this will update gecko to the version you chose, we now need to update gaia to the same version
 
run
 

cd gaia
make reset-gaia

 
and wait and afterwards you will be running the chosen versions of gecko and gaia.

why have I not updated gonk, I will refer you to https://developer.mozilla.org/en-US/Firefox_OS/Platform/Architecture and leave that for a future post
