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.

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
Hello. Make another firmware for the first batch of phones. bad camera, all red. thank
battery drain
Install Battery Calibration and then wipe battery stats file. I don't know if it's my battery or every DG550 it will be 100% then down about to 70% it will stop for hours and then go down to 40% and 30% and stop again. I don't know why. My battery is bad cause it only show 25°C. If it still battery draining install again. It shouldn't do that it's not like Doogee rom!
Blackview rom has same batterie drain as orignal "DOOGEE_DAGGER_DG550_Android_4.4.2015.01.26" Firmware, and blackview has lower antutu scores.
But i like it more than doogee firmware.
I recomended a 3000mha battery, with blackview firmware runs perfect! I don't feel that drain, and i edited the build prop with L Speed Evolution Scripts and High the minimum Cpu Frequency with kernel audit.
Calibrate battery, charger to 100% then calibrate let discharge and full charge again. My battery draining then stop on some value and keep saying same % then go down… It was same on Doogee rom, but on this it last much longer.
hello.soory for my english. i have a huge problem in any program that i put on the g550 . the icon disappears ans the camera does not appear at all.
i rooter dg 550 ans install the .apk file in system/app but nothing changes. you have solution.
thank you. 2 cameras are new.
This ROM does not work for me without coverage. He says the model is DM550. I'll try another.
Yeah DM550 is rebrand DG550, flash in SP Flash tool, they fix some issues, better than last original rom from Doogee
Giorgio8224.this rom works with flastool.
Great Rom, im using it now for a couple of weeks and it works very well, after batt. calibration no more drains.
There was even an OTA update from blackview, when install you loose Root, so you have to do that again.
All works well even after the ota update.
I also have problems with not functional autofocus of camera (First series of devices before August/2014). This problem is with latest Doogee DOOGEE_DAGGER_DG550_Android_4.4.2015.01.26 as well as with Blackview ROM posted in this thread.
Then I wanted to try boot.img as posted by danypava on 06/30/2015.
I get an error S_FT_DOWNLOAD_FAIL (4008) in Flashtools v5.1524.00 whatever I try ("Format All + Download", "Firmware Upgrade" or "Download Only"). When I use original boot.img everything is o.k.
Can you (danypava) or anyone else give an advise how to flash with modified boot.img? Thanks in advance…
Regards
Arno
