[Android General] HyperionAlpha:
The absolute best ROM in my opinion right now is the official 4.4.2 update ROM. It's the first ROM on needrom's site list, linked here (I think) by gixxergabi. I've not seen tell of anyone having any issue at all with this ROM, so it is my guess that it contains the proper drivers for all hardware revisions of this phone. I had a Kit Kat ROM that was functional with my 09/25 phone, even the rear camera worked. But after a while I noticed it wasn't working completely properly. Sometimes the HDR option would turn on and a static-like distortion would move across the screen, the menus would also tilt constantly as if the phone was being rotated, even if it was completely still. The accelerometer seemed to think it was always in motion. This was completely solved by moving to the official 01/16 update.

I haven't had any problems with the SIM card losing signal, but I would expect the latest official ROM to solve that if it were an actual problem due to the ROM that Doogee had worked on. This ROM seems to have fixed every other longstanding issue with this phone, no matter how little or how large. I'd love to use a custom ROM, but nearly every custom ROM for this phone on needrom has major issues (video driver not working for 09/25 phones, camera not working for 09/25 phones, etc. etc. etc.), the official one is just the best and most complete.

You are seeing this error because you need to alter the way in which you are installing the ROM from SP Flash Tools. If you look at the small menu at the top of the list of items to flash, you will see you have the following options: MOTA SIU Like, Format All + Download, Firmware Upgrade, and Download Only. To install previous ROMs and some of the custom ROMs, all you needed to use was the "Download Only" option. To install the latest official Doogee-made ROM, you MUST choose "Format All + Download." If you select this it will check off all of the checkboxes, and formatting will begin before each option is written. Remember, you need to plug the phone up without the battery in first, then remove the cable after hitting the Download button, then plug the cable back in again. Then things will start to move. Because you will be writing everything, you'll need to reflash any custom EBR files you may have used, and you will probably to reflash TWRP or CWM as well. If you uncheck these items to write, then the option to "Format All + Download Only" will change and you will not get the new ROM flashed, so your only option is to flash everything then reflash the single items you need separately.

The only "issue" I've had with the 01/26 ROM is the EBR1/EBR2 files actually. I tried to use the ones edited to provide 7GB for apps. But it doesn't work. When attempting to load them up with the SP Flash Tools, it does not work with the new ROM files in place. How should these be edited to work with the 01/26 ROM?

Edit: Nevermind, I got the EBR1 and EBR2 file to flash by renaming checksum.ini to checksum.old, then it ignored the differences in the EBR files and they flashed. Reboot the phone and it shows the internal SD is damaged, format and you've got 6.98GB per partition again, yay!
