[Upgrading, Modifying and Unlocking] dolence:
After an unsuccesful root attempt on my Blu Studio 6.0 HD, I ended up with my phone recovery being overwritten by some chinese version. This lead me to seek stock rom for this phone. Guess what? I couldn't find it anywhere!

Recently, I noticed Blu Studio 6.0 and Xolo Q2500 seen to be the same product. Maybe a rebranded version?

This is what I did:

Downloaded Xolo Q25000 stock rom.

Downloaded MTK Rom Studio.

Downloaded MTK Droid Tools.

Download Flash Tool.

In flash tool I noticed I would need a scatter file describing the partitons and adresses where each portion of image would be written to.

So, I decided to use MTK Droid Tools to output my actual scatter file and compare to Xolo Q2500 one. They differs:

Beside that, MTK Droid Tools give me a warning message. What it means?

My question is... It's safe to write Xolo Q2500 stock firmware to Blu Studio 6 and how it could be done? Anyone could please assist me on this?

Thanks in advance!
