Try the Nandroid backup / rrestore method. This method is used for backing up the original ROM and recover it when something wrong occures.
I assume that you do not have a backup image of your original ROM.
What you can do is ask someone to do a full Nandroid Backup of their Huawei G740/Orange Yumo and send it to you or get a custom working ROM.
I suggest flashing the custom ROM or someones else's Nandroid Backup using ADB.
