It is the P550. If it matters it is the Canadian version. I am downloading the entire 1.5GB firmware from Sammobile to see if I can get it back to original and have a plan if things go bad again.
1. What root program were you using?
Holding Volume Down+Power while it's connected to power should turn the device off. Did you try that? Otherwise it simply forces a reboot.
Have you tried updating to the recommended TWRP 3.3.1-0 with TWRP rather than with Odin? You'll need to unpack recovery.img from the tar file and flash that via TWRP > Install > Install Image....
Via Odin, I can only successfully install TWRP 3.1.0-0 (which gives those E3004 errors not detecting device model when trying to install any custom ROM - and fails).
I cannot install the recommended TWRP 3.3.1-0 - Odin fails. A later version of TWRP is presumably needed to install the custom ROMs.
Other thoughts? Is there another approach I should consider? Another TWRP version to try?
\BIN\tar --create --format=gnu -b20 --quoting-style=escape --owner=0 --group=0 --totals --mode=644 -f %%~nG.tar %%~nxG
sudo apt install heimdall-flash
I mainly use Windows. When I first started dabbling with putting LOS on a Samsung device, I tried to use Heimdall and simply couldn't get it to connect regardless of which USB drivers were installed. I tried Odin, which worked without any such hassles, so have continued to use it.
mv twrp_3.3.1-0.img recovery.img tar -H ustar -c recovery.img > recovery.tar md5sum -t recovery.tar >> recovery.tar mv recovery.tar recovery.tar.md5
Thanks for providing the code for future users. It's better to DIY than rely on some unknown script, bat or exe file. I put a link in my FAQ to point to this thread/post.
Hi, I'm happy to be constructive. I had to work on upping my post count just to post in here, and I don't know the intricacies of starting a proper forum area for the device. I assumed (incorrectly, I guess) that it was a simple question of simply creating one. Sorry if you think it's all whining, but I've tried to be polite and clear, and I've thanked you many times. I appreciate your work and effort. I'm trying to figure out a way to streamline things.
So, why can't the files be properly posted in this thread along with an updated initial post explaining the process?
