Yeah, OnePlus 5T came with current OxygenOS 10.0.0 (stock Android 10) and TWRP 3.4.0-0.
Neither could I install the grandmaster phhusson GSI ROMs. The device always ends up in Fastboot mode …
OK, good news do me, that the issue is not in my GSI’s, bad news for you that none are working
Have you flashed the system.img via fastboot or with TWRP ?
when flashing via fastboot, have you used the command
fastboot reboot fastboot ? The device must booted in fastbootd !!
Here a tutorial from an Android10 superpartition user who have installed GSI successfull
On my dog walk I have thought about your issue. I think I was confused. Your device has Android 10 installed, but it isn’t’t a Android 10 device with super partition. So I fear the fastboot reboot fastboot to get in fastbootd mode wont work
Only on devices which where shipped with Android 10 fastbootd is available
it seems that you will need some more things to do
Yeah, I guess so.Thank you very much for thinking intensively about the problems I have caused myself.
OnePlus 5T was released with Stock Android 7.1.1 (Nougat) and has been upgraded to Stock Android 10 (OxygenOS 10.0.0) over time - supposedly including Treble Project support. The standard version of TWRP 3.4.0-0 shows the partition /VENDOR. But there must have been something I missed. I will try to figure it out, because I see this as a GIS learning process.
Devices which where delivery with Android < 8.1 are no treble supported devices. You can ‘treblize’ some devices with special patches (shown in the link above), but GSI will always be very buggy.
Well, I know the requirements for “Trebled Phones”. But your statement is not universally valid, because a few phones received official system software updates from the manufacturers who implemented the official Treble support - for example: Samsung Galaxy S9/S9+ and also OnePlus 5/5T. See also Full Treble on Oneplus5 via Phh-Treble by phhusson. There must be other reasons why I can’t get the GSI-ROMs to work. Maybe only GSI-9-Pie ROMs work and not GSI-10Q/11R? I just have to try it to know…
That’s what PHH has told me
I think the problem will be the vendor sources. It seems for me, that the access to vendor diver is different in Q/R as on P. That’s why often P-GSI are working and Q/R-GSI not.
On my MiMax3 the camera doesn’t work with P-vendor sources. I have tried a lot with PHH, but we don’t get it running. After I have upgraded the vendor firmware to Q the camera is working under Q and R.
On my Mi Note 6 pro the same. With P-GSI all working, with Q also, but with R Camera is crashing.
I think if you will get a bootloop and the permissiver don’t solve the loop, it’s an firmware issue.
Yeah, all the information I have found so far on the www suggests that the sticking point is the vendor sources. Just the presence of a partition /vendor is no guarantee for success. Only definitely know I don’t do it.
Why should one use Treble/GSI over the normal method of installing a recovery and ROM? Where does Treble/GSI actually come in and what does it achieve?
