Galaxy S7 not charging while in download mode - Samsung Galaxy S7 Questions and Answers

I have been using my Galaxy S7 with a custom ROM since a while. After flashing a different ROM which I've used before it triggered FRP lock which is also fine. Then when I tried to flash an offical from downloaded from updato.com it got failed and showing a blue screen containing "An error has occurred while updating the device software.....". So I kept my device as it is so that I can download another Official Firmware from a different source/built. Next day the battery got fully discharged and I then put the phone on the charger for an hour or two to flash the latest downloaded firmware. But after disconnecting the charger it stays on for a few seconds and then it goes black. So there's not enough juice left to flash the new firmware via Odin. Whenever I tried to flash it via Odin it starts flashing the recovery then system but the phone shuts down after a few seconds before it even finishes. I have tried charging the device for several hours but no luck. Whenever I connect the charging cable it shows the blue screen above mentioned and I can even navigate to Download mode as well but it goes blank after disconnected.
Please help.
Thanks in advance.

Will not boot into recovery but will boot into download mode.

My phone is rooted with stock rom. The only changes are listed below
Froze bloat that was safe
changed bootanimation to stock samsung
replaced some apps with inverted versions of themselves (ex. google +, stock messaging)
Here goes:
I was using navigation and I noticed that my phone was off after I had finished. Nothing worked at all, I could not boot into recovery or download. I connected the phone to a charger and red led flashes and an empty battery appears. The battery was full. I could reboot the phone while on the charger, but it would shut off as soon as it got to the homescreen. While off, If I pressed the home button, the green battery would appear as if it were charging. From here I could boot into recovery and download mode. The phone will only boot into these modes while connected to the charger. Here is where it went bad. I attempted to restore a backup while the phone was on the car charger and my car charger got pulled out in the middle of a restore. No charger meant that the phone shut off mid restore. Now, when I plug in the phone, the red led appears and the empty battery with a circle inside appears and then goes away. This repeats itself over and over and the phone buzzes when the empty battery reappears. I can still boot into download mode but not recovery. If I try to flash the stock samsung rom via odin, it says that it passes, however upon automatic reboot the samsung appears and nothing else. After the samsung appears the phone just continues to buzz every 5 seconds or so as if it is trying to do something. Could it be a bootloop? I have done a ton of searching here and now I am resorting to help! Your time is appreciated and beers on me if you can help me get my phone back to normal.
Put your phone into download mode and let it sit on the charger for 30 minutes. After pull and reinsert your battery and then try to power on your phone without your charger. Then proceed to charge your phone to full since it powered on.

This did not work but thank you for the suggestion. From what I have gathered, as long as I can get into recovery then I should be able to get everything back to normal. Anyone?

if you can get into download mode, you can use odin to fix everything.
you might have to do a complete wipe but it is what it is

I tried this already. My problem is that after I flash the first bootchain, the second bootchain will not flash. I gets stuck at the setup in odin. I see there is an option to disconnect the phone and exit odin and reconnect the phone without leaving download mode if this happens. My problem is that if I disconnect the phone from the computer or from the charger it shuts off automatically. I tried these steps the best that I could and when I click nand erase and it reboots, then all it does is buzz every few seconds. I then shut it off and do the data and cache wipe and reboot. It reboots and appears to be the stock rom asking me for language and activation after, but the phone shuts off almost immediately and reboots to a blank battery with a circle in the middle. This is after I have had the phone on the charger for a long time. This happened out of the blue after I was using navigation. This problem did not arise from changing something in the system or from flashing a rom or kernel or anything of the sort. No one has seen this issue with the blank battery? I saw someone mention in android forums but the resolution was that they returned it and got a refurb.

[Q] GT-P3100 won't boot nor charge

It's my first time I encountered this problem on my device so I'll try to do my best to give the details. So a few months ago probably early January, I flashed a KitKat ROM on my tablet and it works smoothly so I installed a few apps and allowed my mom to use it for a few months until now. She gave it to me and said that whenever she tries to turn it on, it just shows the Samsung Galaxy Tab 2 Logo and then the screen shuts down and it shows it again meaning it has a bootloop so I booted it into download mode and used Odin3 v1.85 and I chose the firmware file and flashed it and it failed, now it shows firmware flash failed or something like that, so I used Odin3 v1.83 and 1.3 and they both failed. Now I used Odin3 v3.07 and it worked. Now it won't boot nor charge. I tried doing many button combinations and it didn't work. I heard that I need to remove the battery for it to discharge the remaining juice and plug it back in again. So does the method I heard work? If not can you give me other methods?

My S7 Duos is totally unresponsive, black screen but blue LED is on

I had my phone just sitting on a wireless charger this morning and had been there for about 15-30 minutes. I noticed it was rebooting, odd I thought? I took it off and then realized it was going into a boot loop. I gave it a soft reset and then it would turn on and stay on for about 10 seconds before boot looping again. I again gave it a soft reset after a couple loops and now it seems to totally dead, as the title implies.
No button combination has worked and I've held them all down for well over 30 seconds each. I've tried plugging it into my PC and haven't gotten any response that way. The blue LED is on so I know it's not dead...I think? To make matters worse, I bought this phone off Craigslist about 5 months ago and it's the Exynos version so I definitely can't get any kind of warranty on it. I'm hoping someone has had this problem and can help or just has some advice. Thanks everyone.
EDIT: To keep this updated, I have been able to get into Odin Mode and have tried to flash stock firmware. Odin says everything went fine but the phone hangs up at the Samsung Galaxy S7 logo. I'm unable to boot into recovery mode and I've even tried to reinstall TWRP with Odin and that has not worked.
Seen the LED only problem before, waiting for the battery to drain and the phone to turn off seems to be the only known cure atm
Once it does, connect the charger for 15 mins, then boot directly into recovery and clear caches to try fix the bootloop, possible it may need factory resetting / clean flash of stock ROM
Using the MicroUSB > USB white adapter, you may be able to connect a power hungry USB peripheral to the phone to drain the battery faster, I use a USB desktop fan, but some people report it not working when it is stuck in this LED loop and have just had to wait it out
Thanks for that advice, I'll let it drain over night. However, I have been able to get it to boot into Odin Mode and Odin v.3 recognized it. I flashed the stock firmware but upon rebooting nothing happened and now it gets stuck at the Samsung logo screen. I can still get it back into Odin mode, which I believe will be the fastest way to kill the battery, but I find it odd that I can get into that but not recovery? I am rooted and have TWRP installed, if that matters at all.
If you can get into Download (ODIN) mode, then letting the battery drain probably won't help, that only seems to help when the phone is completely stuck with nothing but the LED working
Make sure you flash CSC (Not HOME_CSC) along with the other 3 sections of the ROM, using ODIN 3.12.3, that should factory reset the phone after the flash
If you successfully flashed stock with ODIN already, you are no longer rooted and do not have TWRP installed, flashing stock with ODIN replaces all that with stock
I updated Odin and once again tried to flash the 4 parts, making sure I used the right CSC file, but I'm still getting hung up at the Samsung Galaxy S7 logo. Do you have a suggestion as to which region's firmware I should use? I have been trying the Australia one from SamMobile's site.
EDIT: And to clarify, I have the G930FD(the duos one).

Any region would work, and the F firmware works for the FD too

Help required S7 DUOS [SM-G930FD] hanging during update after flashing stock ROM.

I have been given an S7 SM-930FD [Dual Sim] that was supposed to be bricked. It wouldn't boot into anything but I have successfully got it into download mode and been able to successfully flash a stock ROM downloaded from Sammobile [several times] with no errors. Each time I have used the full set of AP,CP,CSC files and the previous owner is not sure what ROM it was on or what he tried to install. I have tried different versions of the firmware for this model for various android versions and regions simply to try and get it to boot, but without success. I have tried HOME CSC and CSC files too.
But each time it starts to install the update / reboot it hangs. Either when it installing the update on the blue screen with the robot and its "erasing" - small rotating symbol just stops and nothing happens OR it loads to the GALAXY S7 normal boot screen then hangs.
When it hangs it will only respond to one key combination Power + Vol Down. It then "switched off" and will not reboot in any mode. When I say "switched off" I mean the screen goes black. However if I then connect the charger, it won't show the charging symbol UNLESS I leave it for a few hours and the battery goes flat. It will then charge and I can boot into download / recovery mode but normal boot starts installing the update and it will hang all over again. On one occasion it hung with and black screen and blue flashing light but again no key combinations worked and I had to wait for the battery to drain.
Also tried Smart Switch Emergency Recovery. Even with the drivers freshly installed it does not recognise the phone, it does accept the model number during initialisation, but once the S/N is entered it comes back and says it can't find the model, S/N or IMEI in the database!
I have researched the web for hours and watched every relevant youtube video and tried their suggested key combinations etc and they just don't work.
So I'm hoping someone can help me resolve this frustrating situation, not least because of the delays between attempts!
Presumably as I can consistently get it into download mode there is a solution out there somewhere???????
What am I doing wrong? Should I be looking at a custom ROM or trying something else?
All help appreciated.
