It can't work the way you think.I understand you and aggree with you. As i said i m in XEF/XEF/XEF. I have the oreo ota notification. My oem option will back on sunday at 7 a.m but i m ready to try the oreo update this week end to see if the oem option will magically back. So...if there is a way to extract the update zip from my phone , i can upload it here for those who want to flash it with odin. This should allow to get oreo without waiting for samfire or sammobile. The oreo update is 1.4Gb.
If interested, let me know![]()
you can get zip only if your device is rooted and also this zip can work only on matching base. Now if any one have matching base then they directly receive FOTA right?
Another thin you can do is first update to oreo, root your device and then dump all partitions and make a TWRP flashable Oreo ROM. but this is not a cup of tea more everyone. Also if Oreo required Bootloader from oreo base then again it becomes risky to use dumped bootloader. If anything real RISKY in terms of flashing then it is only Bootloader. Even after countless flashing in my life, I always try to avoid flashing BL as much possible.
