Hey guys, I'm having issues flashing ROMs I ported to my Studio X+ D770. I'll try to keep it short: Porting ROMs for this device is going to be difficult, since there are no other custom ROMs out there that I know of for the D770 Studio X+. As far as I'm aware, I'm the first to try, and let me just say that I have zero prior knowledge to this process, aside from everything I've tried trying to get this to work. I'm well experienced with ROM flashing on other android devices, but this is my first MediaTek device, as well as my first ROM Porting experience. When I'm running the 3.4.67 kernel firmware and I try to flash a Resurrection Remix ROM I've ported (I've tried multiple recoveries-TWRP 126.96.36.199, Carliv 2.4.7, CWM 6, all with the same outcome), I get a status 7 error: "ApplyParsedPerms: lsetfilecon of /system/lost+found to ubject_r:system_file:s0 failed: Operation not supported on transport endpoint set_metadata_recursive: some changes failed" Looking at the updater-script, it appears the issue resides in this line: "set_metadata_recursive("/system", "uid", 0, "gid", 0, "dmode", 0755, "fmode", 0644, "capabilities", "0x0", "selabel", "ubject_r:system_file:s0");" Research makes me believe this is an SELinux issue, as seemingly my recovery is incompatible with SELinux (?), and others who had the problem were told to update their recovery to a newer TWRP. For me, even when I try to flash on TWRP 188.8.131.52, which is the newest recovery I can find in an automated tool, it gives the same exact problem. Looking at the ROM page, it says to set SELinux to Permissive and then reboot. I assume this means set it to permissive before flashing, as this notice was put early on in the article. I've supposedly set SELinux to Permissive following these instructions, but even after doing so I get the same issue. Also, keep in mind, when I go to Settings>About Phone on my stock KitKat 4.4.2 firmware, nowhere in that menu does it list an SELinux status, like I've seen on other Android devices running the same firmware. Apparently it's there, but it's also not there... I recently tried a patch that allows one to bypass set_metadata_xxx problems, involving the replacement of the update-binary file. When I replace it and repack the ZIP file, it gives me this: "mount() expects 4 args, got 5" And it exits with a Status 7 error, just like the other one does. Now NOT ONLY have I tried flashing a 3.4.67 kernel ROM, I've tried flashing a 3.10.X kernel ROM as well, which gives me its own unique set of problems. I've tried porting this Temasek CM12.1 3.10.X Kernel build to my device, but that doesn't flash either. I don't get the same errors as before though. Unfortunately I can't remember what errors I got, I'll have to reflash stock Lollipop firmware on my phone and try to reflash the ROM so I can post what it said. I'm talking about my 3.4.67 and 3.10.X kernel issues because I don't really care what kernel-ROM I can get flashed on this thing, I just want to make SOME SORT OF ROM. Any help would be appreciated.
