I've a galaxy s5, on OptimalRom R12, and it gets stuck on reboot/shut down. The Samsung logo appears, the screen goes black, but the light at the top is blue and the nav buttons are lit up, white. I tried flashing the rom in Odin which updated the boot.img, but that didn't fix it.

Having the same problem here ? Using safestrap, when trying to reboot from OptimalRom R12 phone hangs with lights on and I must remove the battery to get back to safestrap boot manager ? Everything else works fine in OptimalRom R12. Just hard to reboot to go back to safestrap. Is it my phone or is this problem with other user's ? Thanks

Yeah...it was having issues with using rom slots...and not stock rom slot. I had the same issue...solved it by backing up...and then installing my custom rom on the official rom slot. But....glad to know there's a proper fix for it.

new as in what version? I could only find 3.75, having the same stuck in reboot problem. Resorting to battery out/in reboot to get going.

So here we go, install the new ROM:
NOTE: when flashing OptimalROM using ODIN of course, to slot-1, do not choose the signature verification, it will fail the install. Uncheck it and the flash will work.
BUT...
to my horror, after rebooting to slot-1 with OptimalROM, the Setup wizard started and wanted to activate the phone!! the home and back key only click if you try to get out of that step. I've waited several minutes now, no joy, no activation, time to revert to the stock rom...more later as I figure this out. Too bad because I enjoyed not having the annoying bootup jingle and the stupid puta red verizon splashy/trashy red screen...

Went to OptimalROM instructions and just as the man says...
You will need to flash the NI2 firmware tar (NOT FULL STOCK) in ODIN
Ok, did that, android updating 284 items..waiting
Here's hoping the activation crap won't happen again, WOWZA
it says activation already happened!! Just follow the directions...

Nice OR homescreen shows up w/o the red puta butting in !! No OTA present that I can see in App Mgr.

It's only using 859MB with 1GB free!! This will be fun customizing.
