Weird problem, could a fauly battery cause being stuck in Odin mode?

[vortexdr15]

I have a rather weird problem and I'm not sure if I should trust the guys I brought my phone into.

Basically it started when i came home. I plugged my phone into charger when it was at about 12% battery. When i came back 2 hours later it has the light blue screen Downloading do not turn off target. ( I never rooted my phone or anything)

I tried to restart etc using home, power and volume down. Then volume down to decline OS update and it would keep going back to the download mode.

I tried to connect it to my pc while in the mode but PC only recognized a usb device was plugged in.

Anyway I brought it to the shop. While going there i assumed that the battery died. We plugged it in at the store and the charging indicator didn't show it was charging (battery image just stayed still with no animation)....When they first looked at the phone they told me it was a dead battery and I explained the situation and brought the phone back to the odin mode using home, power and volume down.

Anyway....long story short....They think its a battery and software problem but the battery thing sounds fishy to me.

A couple questions:

Will a S7 in Odin mode still show the actual charging animations after it has ran out of power?

Any other ideas on what might of happened?

To answer your first question - it might, for a brief moment, flash that it's out of battery, but if it's not charging, you have an issue, and it's probably a hardware issue.

Hmmm to clarify, the charging screen remains on the whole time while the phone is plugged in (it just doesn't show the actual battery moving animation).

If you unplug it, and then hit Home, power and volume down it will go back into Odin mode and stay there for quite a while. I guess question for starters was if the actual charging animation will still play if the OS somehow got scrapped?

And if its a battery issue....have you ever heard of a bad battery causing a phone to go into odin mode? (Something isn't adding up)

Okay, I think I understand the problem better now, sorry.

If you had a software update, or some glitch in the software, it could have corrupted your OS leaving only Odin to boot to. If you can, I'd call Samsung and let them know what happened. You might be able to get some help in the Samsung dev forums, too.
