DESCRIPTION
Best ROM for thise phone. Lollipop and Marshmallow will have lot of bugs. This is the best you can have. This phone has bad roms and support, you can't have anything better than this rom.
Never buy Doogee smartphones again they lie! Battery is only 2200mAh, remove the sticker from battery and find out how much do you have! They did it with the newest smartphone too and I bet they lie about capacity on all of the smartphones!
Also this rom has OTA update! Guys from Blackview are better than the original producer! If you do some tweaks in system partition, you have to flash clean rom and then install OTA, you need original recovery.
OTA UPDATES:
-
20150714 – System optimizations and bug fixes
-
20150906 – System optimizations and bug fixes
I recommend to flash clean rom then download and install this OTA update. Install one by one as described in updates. You will need original recovery! Can not be install if you edit or add files in system partition!
Anybody successed with making this rom as zip flashable file? 
I Don't have working Meta-INF file
Update is possible over the OTA only. I don't have the flashable file. You need original recovery.
Rom for DG550 by Doogee edited by Blackview for their DM550 which is basically DG550 rebranded.
I'm using it about week and it's working good. A lot better than original 4.4.2 rom by Doogee.
Watch updates on XDA thread
Installation
Donwload newest SP flash tool and flash this to you phone like original Kitkat. You can also use TWRP 2.8.1 But I've got errer when I flash this recovery, but it was flash anyway. So I recommed flash whole rom in SP flash tool than flash again only TWRP 2.8.1 if it end with error never mind it should be flashed, I try to flash it again and it was end with error again but when I booted to recovery it is working without errors. In recovery flash Super SU 2.46 for root, working great! Then install KingoUser from Google play, there is a half rooted issue with SuperSU
Edit use the newest TWRP working for you. OTA working only with original recovery!!
If you don't you custom recovery, for root use Kingo Root.
Now you can flash TWRP in MobileUncle (2.8.1 doesn't work for me, only in SP flash tools with error but worked) you can flash TWRP 2.7.1 or other recovery.
You can follow this video. Don't forget install drivers if you don't have it!

Pros
- No more battery drain!
- Deep sleep working great
- Should included new camera driver – Let me know if it is true.
- Multilanguage
- Based on latest Doogee rom
- 3GB for APPs
Cons
- No gps.conf – Reset GPS in MobileUncle and download Faster GPS and make gps.conf file just right for you.
I will update it with GPS.conf file and other stuff, but I'm going on holiday for a week so it will be in the end of the June.
Tweaks
Use L speed from Google Play and download Viper4Android for better sound!
※Please make a backup of your device before installing or updating ROM
Excellent rom!!! Everything is working great and way better than Doogee stock rom
battery life is better and recieved 2 updates Thanks Bro I will make a Donation soon 
Is not necessary it's not my rom. I would like update this, but without meta-inf folder I cannot make custom flashable rom.
Yeah they do OTA updates and Doogee said they can not…
Nice rom but … no more mac adress, no more ip avalable… so no wifi…
I don’t have nvram backup (oups !)…
Need help please.
Oh man. Never update rom with SP flash tools without NVRAM back up! Do you have any TWRP backups? You need restore it, it should restore NVRAM also.
How dumb dalvik for art? Phaco the normal process and then restarting continues dalvik. Someone help me please?
Somebody help me please??
Don't do that! On Kitkat it's not working very well. But you can try your best in Developer options.
nice Rom but i have problems with bluetooth pairing in my car, PC, Notebook… please help, thanks
I have Blackview DM550 and i root it with search4roots. It so compatible to my phone, it's safe and easy to install.
Hi,
First of all, Thx Mattthev for this ROM.
After installing this ROM I got 3 problems:
- GPS keeps disconnecting and reconnecting. Does the problem you describe in the ROM been fixed?
- Camera doesnt focus (There's a correction for this in the comments)
- Phone is unable to install your updates. After downloading, the phone reboots to install the update, but when it turns on the update isnt installed
I have zero experience in making changes to files on the ROM to fix camera and others. Just for installing this ROM I lost half a day.
Is there any way to upgrade the files to use SP flash tool with the latest updates? I mean, allow users to download the folder you have here with the latest patches/updates/fixes
blackview dm550 can flash this?
i have problem with this rom. camera is very bad. when i use another boot.img camera dos not work. when i take photo phone turn off. please help
