So... did you try flashing a new copy of TWRP via Odin - you should still be able to get into download mode right?
Also... Breath... take a few minutes away from it... drink a soda or water or whatever and try and get a fresh perspective on things...
He's right. Leave your phone alone if time permits, watch TV for a bit, get a drink, come back to it. While you're doing this, you may hatch another idea, or it may just magically fix itself, weirder things have happened.
Too many times I've kept pushing forwards on something and not thought of a possible solution and fubared something way worse because I was trying everything without thinking through what might happen as a result...
No, I hear what you are saying and I really have tried everything I could think of. No idea what happened but the phone seems truly gone. It will go into download mode but will not do anything else. I tried twrp with odin, I tried the stock md5 recovery with odin, and I even tried Kies and none of it works. The only reasonable explanation I found online is one post which said it's possible there was a short in the phone's hardware and the memory is gone.
I have a new phone on the way from Tmo, supposedly it's delivered tomorrow so I'm 2 days without a phone.
Do any of you have experience with Tmo warranty exchanges? Is there any way they will be able to see that any changes to the phone and deny warranty replacement?
