Ok. Let me start this out by saying that this procedure is very risky...I'm not even sure why I followed through with this....but, I will tell my story and you can decide if the risk is worth it.
I was running the 4.3 locked bootloader VRUEMJ9. I was running SafeStrap with N3bula ROM. Like many others, I've been frustrated with this locked bootloader...So, for the third time, I decided to test this method to see if I could downgrade back to 4.1
Using the knowledge from KOBOL, and the very helpful write-up by GiGaLeOnZa, I spent over an hour trying to hold the battery in place and short that little tiny resistor. After an hour, I finally got the stars to align, and was able to hold everything together while pressing the power button. As I counted to 6, the screen flashed white, and I pulled my screwdriver off of the resistor, and the screen stayed white for another second, then went black. After thinking, "oh great, there goes my phone" I reconnected everything and prepared to put my bricked phone back together. Imagine my surprise when I turned it on, and the safestrap screen appeared. After hitting continue, my phone booted in system recovery mode. I chose the "update from SD card" option. This resulted in a failure to mount. So, after I realized that I still had to imaged SD card in the device, I turned it off and put my normal SD card in. When I booted my phone, N3bula loaded like normal, and I was able to check my e-mail and voicemail. So, obviously, I felt like I needed to mess with it even further. Brazened my the backup I had made yesterday, I decided to ODIN the root66 firmware onto the device. After ODIN declared the process successful, I waited with my breath held while my phone booted up...After what seemed to be a long time on the "Samsung Galaxy Note II" splash screen, the little Android with an open chest appeared with a status bar. After that had completed, my phone rebooted and I went back to holding my breath. When the phone got past the first splash screen and the old "4GLTE" logo with the emanating rings appeared, I almost fell off my chair. After an eternity, my phone turned on and finally, what we've all been waiting for....Attachment 2713239
Now please, I beg you to read this whole post before you decide to do this yourself...as I said before, this is extremely risky, and I'm not sure if I just got lucky, or this worked.
Huge thanks to GiGaLeOnZa and KOBOL for their extremely helpful guides and knowledge.
Yes, I tried the combination of those two image files (cause I wasn't sure which one applies to my case), with winimage and winhex. Same result. I also tried screwdriver and pincet to short the resistor. After pressing the power button, screen remains black before and after I remove the screwdriver. I'm quite sure I hold the battery right, because if don't short the resistor and simply press the power button, it will display logo in loop. And I tried above steps many many times.
I wish I could, but I haven't been unfortunate enough to install the new locked bootloader. If I had by mistake, I would want to try this to unlock, but I was lucky enough just to bring my phone back to life, I'm not courageous enough to update then try and go back. I leave that to the people who are locked and want to be adventerous enough to confirm what ioc did.
Yea, if you weren't holding the battery right then the phone wouldn't be turning on, unless you have the USB cable plugged in. I opted not to do so, because when the board gets power it will try and start charging it and wouldn't start the boot looping..
Keep at it, I got mine going on the 3rd attempt to power it up. Make sure your counting exactly to 5, 6 tops. I'm not sure what else to say, but if in the event you can't get the phone reset via micro SD and can't ODIN back, you're stuck best of luck.
