TWRP on Samsung Gear

Have an old Samsung Gear watch that is running Android 6.01

Would like to flash TWRP onto it. It flashes fine and boots into TWRP.

But at the next system boot it's being returned to stock recovery.

I know this is a known problem on some devices.

I've also tried flashing both TWRP along with a patched boot.img created from the stock boot image using Magisk (on another device) That patching proceeded fine with no errors.

At this point TWRP "stuck"........ but it "stuck" TOO well. The device boot looped in TWRP.

Advice/thoughts/comments???

I'm pretty sure I know what the issue is as I have dealt with this device before. Post the steps you have taken and I can see if i can help you.

Thanks for the response. What steps are you asking about?

I thought my OP pretty much covered that, but maybe I don't understand your response.
 
You're missing steps after the Twrp install. You need to run a few adb commands after installing Twrp.
 
$ adb shell

$ su

# mount -o rw,remount /dev/block/mmcblk0p20 /system

# rm /system/recovery-from-boot.p
 
I would start over, reflash the firmware for the device. After it boots and is setup. Root, flash twrp, run the commands above.

I'm still confused..... I just flashed TWRP using fastboot. If I reboot to system, I lose TWRP.

But unless I reboot to system, I'm not able to issue the ADB commands you mention.

What am I missing??
 
You should be able to run adb commands in Twrp, sounds like a driver issue once you're in twrp. I will check the thread in a bit. rooting a S10 for a client in S. Africa at the moment.

When you boot into Twrp look at device manager on the PC. Sounds like a driver issue.

I may have partition problems as well. I notice that when I DO have TWRP working, I see partition errors (like not mounted, no such device, etc) in the mount screen, etc.

I've soft-bricked the device so many times, I'm getting disgusted. This morning I had one heluva time getting the watch to connect to Odin to factory-restore it.

Maybe I should just give it up; I've been trying (off and on) for several YEARS. 8-(

I'm not familiar with that specific device but I am familiar with MM, Root, Odin, TWRP and softbrick issues. It would be helpful is you provide the exact fail or mount issues for instence fail to mount efs, DM'Verity fail, DRK. The partitions could be incompatible firmware had to say exactly what without more info. Try checking your download with an MD5 checker and make sure the Official OEM firmware is the exact one for your specific model. Good luck

Thanks the error is (from the TWRP mount tab) failed to mount '/system' no such device

Also the system partition size is shown as 0; which is strange since I can boot into system.

I think you best bet is to wait for James L. as he has experience with that pericardial device. If it was a Note 4 qualcomm I could definitely provide you with forst hand knowledge. If I think of something useful to provide, Ill post back. Im sure you in good hand. Good luck
