@Aliixx@zaabolla is right. Just extract with Huawei update extractor and flash it via ADB.
If i remember correctly the command is
adb flash recovery [path to file.IMG]

Without knowing which firmware was installed prior to bricking, there's no way to flash official ROM directly.
But since you only have access to fastboot, this is gonna be a pain in the ass, but here's what you'll have to do.
-Download official B609 somewhere (i'll post a link if i find it)
-Download Huawei Update Extractor here:
http://xdaforums.com/showthread.php?t=2433454
-Open the UPDATE.APP in Extractor and extract ALL files that you find in there.
-Now fire up your ADB and start flashing 1 by 1 (NOTE that not all .IMG files are flashable, some files will come back with error code, other will make your ADB hang and you'll have to restart ADB and disconnect/connect phone to continue)
-If my memory serves me correctly, the command is
! NOTE: your bootloader must be unlocked in order to send commands to your device.
To unlock bootloader go here:
https://emui.huawei.com/en/plugin.php?id=unlock&mod=detail
(Chinese site, takes 5 minutes to load the page, but it works! Proof attached!)
adb flash recovery RECOVERY.IMG
adb flash system SYSTEM.IMG
adb flash boot BOOT.IMG
adb flash cust CUST.IMG
adb flash userdata USERDATA.IMG
adb flash cache CACHE.IMG
And so on and so forth....
If you're succesful you'll get back at least your standard 3e recovery.
From this point on you should be able to flash official B609 and unbrick your device.
If your device hangs on first bootup, go back into recovery and wipe data/factory reset.
Let me know how it works out or if you get stuck somewhere.
