[Q] I think I'm hard bricked
Ok, first of all, I take full responsibility and made some really stupid mistakes. I consider myself an experienced Android user and have been flashing ROMs and radios since the OG Droid.
I am, however, new to Samsung/Touchwiz, and made an error I'm trying to determine if I can repair.
I have not flashed any custom ROMs on the Note 2, but I was unlocked/rooted with CASUAL. I was having some issues with my proximity sensor and my capacitive button lights, and decided to ODIN back to stock. Here is where I screwed up, I think. Instead of flashing like normal, I think I want a completely clean slate, and I checked Nand Erase. I know, please don't bash me, the brick sitting on the table is punishment enough. I was thinking of erasing backups, as in Nandroid (Nand) backups.
Well, everything flashed as normal and the phone bootlooped. No biggie, booted into Recovery, and it gave the warning it couldn't mount the /data partition. I did a factory reset from stock recovery, and everything seemed fine. The phone booted correctly, but it wouldn't activate on Verizon. It finally allowed me to skip set up, and I found the dreaded "Unknown" IMEI.
No, I didn't have a back up of the IMEI. I began reading and studying on ways to fix this, and it seemed simple enough, but I couldn't get QPST to recognize my phone so I could repair the IMEI. The computer could see it on COM5, but QPST kept saying No Phone.
I tried a few other methods, including EFS Professional and NV Item Reader/Writer. But everything said it couldn't communicate with the phone. I made sure I had it in the correct mode in the Phone Util hidden menu, checked USB cables, ports, and drivers a hundred times, with no joy.
Then on a whim, I checked my /efs folder with ES File Explorer, and the contents are empty. Not sure how I erased all the contents, but now I'm pretty sure I'm screwed.
I wanted you to know my steps, before I started asking questions.
1. If I can get another working Note 2, is it possible to use a copy of that phone's /efs folder on mine? If I can get QPST to work, I could then use it to inject the correct IMEI back into the folder.
2. Is there anyway anyone here could upload their /efs folder so I can try it?
3. Any suggestions on QPST and getting it to recognize my phone?
4. Am I just completely hardbricked and out of luck?
