Has anyone succcessfully rooted the device?
Plz let me know. It is almost useless without root. My personal view.
Hunting for a successful root method but in vein.
Also, need to know how to unlock bootloader for a dual SIM phone?
Because it has two IMEI numbers? Confuses ?!?

It helped me to root this device perfectly.
Works well with 4.4 KitKat too 
Download Towel Root from Web Browser & put it in your SD card then install. Once installed open Towel root register and then root and install Super SU.It works great even though it will be detected as a malicious app in some antivirus apps.Worksw great in my E1 Kitkat version causwe now i can use GL2SD for playing huge games like Fifa 15,NFS MW..etc..Happy Rooting...
Disclaimer: Root at your own risk.Some knowledge is required in case your phone gets bricked.You must know how to install firmware Kitkat or Jellybean.
device not supported for my E1
depending of the firmware version
08 and 10/2014 are only rootable by reinstalling boot kernel of 1st version of kitkat, and using towelroot (see tutos on xda)
last version (06/2015) could be rootable with Root Genius. To confirm
I just bought myself an Xperia E1 and googling on how to root it brought me here. I tried a lot of methods and the one that worked is this one. It also tells you how to get CWM (a custom recovery) onto your android phone.
