[Verizon] ROM flashing using Odin on Galaxy S4 interrupted. Odin is still running. Is there anything I can do?

    I was re-flashing the firmware on a Samsung Galaxy S4 using Odin*, and the USB cable was bumped, which made the update fail. I reconnected and attempted to flash again by clicking the Start button. It seemed to be progressing, but Odin's blue progress bar continued from where it had stopped instead of starting from the beginning. After a while I got the following warning message from Odin, in red text and repeated 19 times:

    followed by this at the end:

    I attempted to start the process again (by clicking Start in the Odin desktop app), but it failed multiple times. I also tried clicking Reset and starting again. It doesn't seem to be possible to do anything from within Odin on the phone. It doesn't respond to any buttons and doesn't react in any way when I try to start the process again from the computer (no more messages on the screen, and no movement in the progress bar, or anywhere else). This doesn't necessarily mean it's frozen, though, because I don't believe it's intended to be interactive. The blue progress bar on the phone is all the way to the end, where it has been since my second attempt to flash.

    I have not restarted the phone, because I am afraid that if I do that after an incomplete flash, I will not be able to get back into Odin. It is still on, still in Odin, still showing all the errors. The desktop Odin app on the computer can detect when the phone is connected and removed (I get the "Added!" and "Removed!" messages).

    Am I correct in my concern that I'm likely to brick the phone if I attempt to restart without flashing successfully? Is there anything I can do to restart the process? It would be an astounding design flaw if Odin really isn't capable of restarting a failed flash to allow for recovery if the process fails and the device has not yet been restarted and Odin is still in RAM.

    I know for a fact that the ROM file I'm using is valid and that I'm doing this correctly, because I have gone through this process several times and never encountered a problem until this time when the connection was interrupted. I have no support available from either Samsung or the carrier (Verizon), because I bought this phone used on eBay specifically for experimenting with things like custom recoveries and ROM flashing.

    Keep in mind, the whole point of the question is that I'm concerned that if I restart from this state, with damaged firmware, I won't be able to get back into Odin download mode, or into recovery or anything else, so any suggestions that involve restarting the device would miss the point. For all I know, Odin might only exist in RAM now; the failed attempt to flash might have destroyed it in the ROM, and I won't know if it's still available unless I risk restarting. I'm well aware that if I can restart and get back into Odin, I can restart the flashing process. What I'm asking is whether there's anything I can do while the Odin instance in which the process failed is still running, before taking the risk of rebooting and seeing if I can get back into Odin or recovery.

    [I also asked this at the Android SE site, in case anyone has an answer and wants to post it there as well: android.stackexchange.com/q/85371/58269. Keep in mind that the SE site has a Q&A format rather than a discussion thread format, which means you should only post an answer if you're actually providing an answer to the question.]

    * When I say "Odin", I'm referring to the Odin download mode on the phone, not the desktop app. When I want to refer to the desktop app, I specifically say "the Odin desktop app".

    If I were in your shoes, I'd pull the battery, boot back into download mode on the device, restart ODIN and try it again.

    By the way, welcome to AF:)

    Oh, and also by the way, I think that I will move this into your device forum for ya;)
    That cool with you?

    See the second to last paragraph:

    I understand that IF I can restart the device and get back into download mode, THEN I can flash the ROM again. The problem is that it's anything but a foregone conclusion that I'll be able to do that. If I restart, I could end up with a bricked phone that can't get back into either Odin or recovery. That's the entire point of the question. The question isn't "I'm stuck in Odin and I don't know how to restart my phone so I can try again"; the question is whether there is anything I can do to flash again, while Odin is still running in RAM on the phone, before taking the risk of restarting with damaged or incomplete firmware.

    In case it was unclear, when I say "Odin", I'm referring to the Odin download mode on the phone, not the desktop app. When I refer to the desktop app, I specify "the Odin desktop app". In all other cases, "Odin" means download mode on the phone. Obviously I'm not worried that restarting the phone after an interrupted ROM flash will somehow prevent me from running the Odin desktop app on my computer. I'm worried that I might not be able to get back into download mode, because that's part of the firmware that I wiped out without completing the process of writing new firmware. I've seen countless forum posts from people who couldn't get into either Odin (download mode) or recovery after an interrupted ROM flash and were advised to send the phone back to the vendor for repairs (which is not an option with this phone).

    [Feel free to move this to wherever you believe it's most likely to get useful answers.]

    Oh, yeah, I'm very sorry. I did miss that part of it :(
    I see you've highlighted it now.
    But as far as the current state you are in--phone on download mode, ODIN program on computer basically stuck--you are wondering if there is any phone key combination, or perhaps some computer commands or some options in ODIN that will allow you to restart the process or at least finish the firmware flash?

    Honestly, I don't know and I don't think so. That's not to say that there isn't a way, I'm just saying from what I have read here and there, there is no way.

    However, let me move this thread into the root forum for your device and carrier, as the folks who are rooted may be able to help:)
