REPORTING all things worked for me in L-10 ROM, after hours of trying reversing from ROM 3.0 to 2.3 using several methods, finally is working. Thanks and congratulations for your job !!!!!
After installation the system is asking me to install an update to B126 automatically, this is fantastic since the updates will come to the device normally !!!!!

Unfortunately it doesn´t work on my L10. After flahing stock recovery and cust.img the update starts but fails just some seconds later. ("software install failed! Get online help from..." and "shutdown system now"). Any ideas? I am coming from the se7en ROM with Emui 3.0.. :confused:

I don't understand something.
You said "You must be on p7-L07's" but this diy is for p7-l10?
I'm on P7-l10 B609 emui 3.0 and I want to roll back to emui 2.3 b126 official firmware.
How can I do that?
I've tried what you wrote but my phone get stuck

Try this one... unzip update.app to sd card/dload and do force update ( vol +, vol - and power on)
REMEMBER, everything is done at our own risk!
Goodluck!
