Hi,
I failed to root DG280, I regret not reading for example viperasp's hint that from software version r10 it can brick the phone.
I used Kingroot, after second use, it told me everything's fine&rooted. I used then some script that removes Kinguser and puts SuperSU in place of it, it also went OK, SuperSU told it wants to update itself, but it was not possible without restart. But after restart I don't have phone running, so...
Would be really great if someone who went over flashing something to DG280 via some kind of SPFlash tool could share how he/she did that. I got only one tutorial from doogee.cc written in some chinese-english. I downloaded r6 image (the only available at manufacturers website, I don't care about version, just want to have this phone running) and can't flash it... I wonder what version of preloader driver can make this phone visible in SPFlash. Attached "Smartphone multi-port download tool" doesn't see the phone.
Depending on how I'm connecting it - with/without battery, with some/without any keys pressed, it is seen in task manager under ports. Sometimes as "Mediatek DA USB VCOM Port", sometimes it gives continuous appearing/disappearing for ~2sec. of "Mediatek Preloader USB VCOM Port", sometimes USB VCOM Port or MTK USB Port, and Flash tool won't find anything in these cases. Sometimes "MTK USB Port" is left (not disappearing) and this is promising, because Flash tool finds one Com port and displays "COM49 + N/A, scan failed".
If I only got it to display both Preloader COM and MTK USB Port so I think I could do flashing. But how to achieve this?
I tried this on Win XP 386x and win10 x64, same results.
Maybe someone has some knowledge now and is kind enough to share/give some tips? Would be great
