Upgrade Firmware

Some devices gets exposed to android development community before going live into market and there will be some device which will see hardly see any development even after getting released for more than year.Samsung galaxy E5 is one of those device for which it took too long to get exposed to custom android development.Even it took a lot of time for the root exploit to come into public.

But the important thing for custom android development of galaxy E5 E500H is the recovery which is already available.But there are almost no custom roms available for galaxy e5 E500H till now.There is only one custom rom which is also the important one and has the possibility of becoming a base for coming custom roms it is none other than Cyanogenmod.

This is not the latest cyanogenmod that is Cm 13 but it is based on android lollipop 5.1.1 that is Cm 12.1.If you are disappointed with this then one good news for you is that all other devices which received cm 13 are unofficial build and are not that stable.

This custom rom for Galaxy E5 E500H is not that stable but as being a first custom rom you can try it on your device and see how it runs.Since there are lot of variants of galaxy E5 you have to be careful on which model you  are flashing this.If you don't have E500H then its better to stay away fro this as flashing this on other variants might brick it for sure.

Since flashing is a risky process we take no responsibility for any type of damage that can happen to your device if it fails.So proceed at your own risk.
