I borked my Galazy Note II.....:(
I had felt confident enough to attempt installing a custom ROM. But first I wanted to make a backup of my current Rom.
I booted into recovery mode (pressing volume up, power, and home button simutaniously). But with the stock bootloader there's no option to backup. So I figured I had to download and install a custom bootloader like Clockwork mod to enable that option right? I watched this video and followed the instructions on how to download CWM. My phone was listed there so I chose it, I clicked on 'flash clockwork mod recovery', and it did it's thing. Seemed to be going fine.
But once I restarted my phone that's when I got the dreaded 'System software not authorized by Verizon Wireless has been found on your phone. Please turn off your phone and go to the nearest Verizon Wireless store for help.' Apparently Ithe problem was becuase I didn't unlock the bootloader first..?
Word of advice for Galaxy Note 2 users...
DO NOT USE ROM MANAGER!!!
But all is well in the end. Some more googling and this is what got me back to stock and running again!....:) But first I had to download and install these drivers (Kies). Without them Odin doesn't see my phone. It takes awhile so be patient and don't think the install is in an unending loop like I did. They eventually install enabling Odin to see my phone and continue on.
So I totally bricked my phone again! This time I couldn't do anything with it at all. Couldn't boot into recovery or download mode. Nothing but a split second Samsung logo straight to the Verizon unauthorized software warning screen so trying to use Odin to flash back to stock was useless.Odin couldn't see my phone.
I attempted to return the phone to Verizon playing dumb like I had no clue what had happened. They said sure they'd replace my phone for me since it was still under warranty but that they'll send it in to tech and if tech determines that it's been rooted I'll be charged full price for a new phone. So I brought the phone home thinking my only alternative was to send it in to MobilTechVideos.com and pay $60 + for the jtag brick repair.
I got pretty frustrated and here's where I'm not sure what happened in the interim to save my phone. I browsed the web a bit looking for any answers as to how I could un-brick this phone. I came across this thread on xda-developers forum about this toolkit. I downloaded my version (SCH-1605) which looked to be a long download. So I sat back to wait.
In the meantime, I uninstalled everything having to do with Verizon, Samsung and Kies from my laptop. All drivers and software I could find. (I use Geek Uninstaller. It gets rid of all traces that software tries to leave behind).
I took the battery out of my Galaxy Note 2 and put it aside. I then proceeded to watch some online shows. I was troubled about what I had just done to my phone and I wanted to chill out and quit thinking about it at least while the toolkit finished downloading. I ended up falling asleep for an hour.. When I woke up I decided to see if I could swap my SIM card from my Galaxy Note 2 to my old HTC Thunderbolt so I'd at least have a working phone for now. Turns out it didn't fit. So I put it back into the Note 2.
By now the toolkit had long been done downloading. I installed it and put the battery back into the Note 2 and just for kicks attempted the 3 button thing. I pushed the volume 'down' (not up) simutaniously with the power and home buttons and to my surprise a screen came up (image 1) warning about installing "Waringing A custom OS can cause critical problems in phone adn installed appplications. If you want to download a cutom OS press the volume up key. Otherwise press the volume down key to cancel.
I'm not sure exactly what made my phone all of a sudden respond. Was it the taking out of the battery for a few hours? Taking the SIM card out? I hadn't plugged it into my laptop via usb yet so couldn't have had anything to do with the toolkit but whatever it is my Note 2 was now working! At least as far as getting to download mode.
So after the 3 button proceedure and coming to Warning screen I then pressed the volume up button to get into download mode (image 2). So now that I was in download mode and had the neccessary drivers from the toolkit installed I plugged into my laptop via usb and Odin connected with my phone.!
I then procceeded to follow the previous instructions on flashing back to stock ROM through Odin (above) and I'm happy to say I now have a back to factory working Galaxy Note 2!....:D
Turns out what I thought was a hard brick...wasn't..?
