Recovery booting blue text loop: Brick? - Samsung Galaxy S7 Edge Questions and Answers

I have a USC S7 edge. Stock rom, no mods. My battery life is toast so I opened the phone to replace the battery.
I changed the battery. Plugged in for the first time and all it did was flash the battery icon with the lightning bolt when plugged in. Wouldn't boot.
So I tried the power with home button while plugging in, it brought up the galaxy s7 logo and just went into a boot loop doing that.
Next, I tried booting into recovery, and now it whenever a charging cord is plugged in, the recovery booting logo just flashes. I can get it to go into download mode only when plugged into a wall charger. It won't go into download mode when plugged into a computer.
I removed the battery completely and it exhibits the same behavior when plugged into USB.
Any ideas? Is my device bricked? Could it be just the battery is defective? I can't test my old known working battery as it was discarded. I have another battery on order and it should arrive in a couple days.

did you make sure that nothing was disconnected or moved when replacing the battery.
you may have partially disconnected a cable when opening your phone up.

When I bricked my phone I went into recovery and reset everything but after it went into the loop you are describing. All I did was boot into download mode and flashed stock to make it work again.

Any advice on getting it to go into download mode when connected to a PC? Mine won't- perhaps thats due to the battery.
It will go into download mode when plugged into a high amp wall charger

[Q] softbricked with no info

Ok my buddy has an atrix 4g for ATT. he 'said' he was in cwm and loading a rom and now its softbricked. though i am familiar with droid, after reading recovery threads and everything, im still unsure of my resolution. most threads tell me i need an unlocked bootloader, others say not to flash if you were on this version. Honestly i have no idea if the BL is locked, what version or update he was on. at the moment it says failed to boot, starting RSD mode, battery is too low to flash.
A. will it charge while it says that or how should i charge it in this state?
B. after it does charge, what should i flash to it?
I apologize that i dont have much information. you have no idea how long it took me to find the power button lol. I appreciate any and all suggestions. Thanks
You definitely need to get more information from him before you can do anything. If his bootloader wasn't unlocked, then he was likely trying to flash one of the P-Roms like Greyblur or Gingerblur, in which case your solution will be a lot messier since the only way I remember accessing recovery back then was by using Tenfar's CWM app that reset it to recovery w/ a wall charger.
As for charging the phone, I don't recommend keeping it on and plugged in, in the chance that it doesn't charge and you are left with a dead battery. When the phone is completely off and you plug the charger in, do you see the charging battery?
When the phone is plugged into the wall charger it boots up automatically and says failed to boot 1, starting rsd, battery too low to flash. If I plug it into my pc the green power light turns on but nothing else happens. I never get any pictures on screen. No battery and no motorola logo. He was on 2.3.4 but he took his sd so I couldn't see what he was trying to flash. I will try to get more info

Same thing happened to me, and I can assure you it doesn't charge in that state. I have to find a way to charge the battery now... It is 0% dead. I hope I can use RSD Lite to fix it when it is charged.
alright, what happened was his battery was too low to finish the flash. it died halfway through, and now the phone is in some sort of limbo state that is just completely unusable.
but, if you have a spare USB cable you can fix this.

just watch that video, and let your phone charge for about half an hour to 45 minutes. after that, reflash the pudding .sbf with rsdlite (unless you can boot into recovery, then you can just reflash any ROM)
If you can boot the phone into recovery by holding the volume down key when powering on, then simply find the alien rom, save onto your SD card from the PC, then install in recovery...then you should be able to reboot into a working phone and charge. If you can't boot into recovery, and the phone is stuck on the "starting rsd protocol" screen, than...I think its a paper weight, but I could be wrong.
Although this problem could probably be fixed by an earlier post, I'm curious....
what would happen if you plugged it into the wall charger, let it boot up into the boot loop, then pulled the battery, left it out for 30 seconds, then put it back in. (this is without unplugging it from the wall charger). Does it allow the phone to stay off and charge, or does it still automatically boot up? Just curious.
im gonna look at the youtube video. ive got a D3 and i saw where a kid had cut a usb cable and made something work for 30 minutes and was able to flash again, but i was def trying to avoid that lol. also, there is no loop really. it doesnt restart, it just sits there. when the battery is pulled, it still stays on the same screen and never powers off until the charger is removed. i may see if i can get a new battery. i really apprecaite the feedback

It will not charge in this state
well my only option at this moment is to try the usb trick. im trying to strip the wire and hook it to the connector on the phone and then just smash teh battery on top of it, but i have no idicator light, so i dont know if its charging. would it charge if i tape/rig/solder it to the battery itself and not have it in the phone? i really dont wanna try a wall outlet charger
I am going to splice a cable and report back with results. My only other option is to charge the battery in my friend's Droid X
If that fails, to AT&T I go.
i havent been able to get it to charge through the usb using the red and black wires. i was very careful and have a decent set of tools to work with. he can buy the external battery charger for $30 if he'd like. im not really sure what else to do at this point.

[Q] Battery issue or bricked? full symptoms list

From what I've read, a bricked phone and the known battery issue seem to have very similar symptoms.
Long story short: I was running a benchmark and the phone turned off and would not turn back on, and there was no red charging indicator. I let it charge overnight and now I have a blinking red charging indicator and I can get into Bootloader and Recovery while plugged in to the stock charger (5V 1.2 amp), but not when plugged into the computer (5V 500mA). I tried restoring AND full wipe/ fresh install and it still won't boot. When plugged into the computer I can get to the bootloader for about half a second and it will turn off. Also I can get into "download mode" on either connection, and I did not have "USB Debugging" enabled when it first turned off. What is download mode and how do I use it?
What do you guys think?

flash the factory img via fastboot.
I have the similar issue, I can't charge the battery, while charging there's about 3mins RED LED last(not flash), hold the three buttons, but just a black screen, no bootloader no download mode.

bootloader is power button + volume down
How? I can't get to fastboot while its hooked up to the computer. It will only go into the bootloader when its hooked to the stock charger.

S5 Strange USB/Power Issues

The other morning I woke up and my phone would not turn on after being on the charger overnight on the night stand.
I removed the battery, power drained the device and still the device would not post.
So I grabbed my spare battery and tried that, still no post.
I plugged in my device and noticed the charging light was not coming on, so i tried a different adapter and yet again no change.
I disassembled the phone and swapped out the USB flex cable with a new one, still no change.
So I plugged the device into my computer and I received a battery gray battery image that flashes away almost immediately.
I unplugged the phone held the power button down and plugged the phone back in. I received the Samsung writing with the model number but the device just goes back to the grey battery and flash away,
I attempted to boot the device to recovery mode but it just loops back to the grey battery,
I had then decided to try download mode with odin and restore the stock ROM. I can get the device into download mode but no computer recognizes the device in device manager or odin.
I have removed and re-installed the battery while in download mode and any computer will still not recognize the device.
I noticed one strange thing. If i remove the USB cable from the phone while it is plugged in the phone powers off and will not turn on until it is plugged into a power source.
It is almost as if the phone does not recognize that the battery is even plugged in!
If anyone has any ideas or could possibly point me in the right direction that would be greatly appreciated!
Thanks guys in advanced if anyone can offer any information on this issue!
Also, the phone is out of warranty!

Samsung SM-T230NU : Won't boot, keeps flashing boot logo

So, I have a Samsung SM-T230NU. When I tried to power it on, it flashed for a split second the Samsung Galaxy Tab 4 logo and then went blank. I figured it was out of juice, so I plugged it in and let it charge for an hour or so.
When I came back, it was flashing and going dark.
I tried a different cable. As soon as power was applied, it flashed and went dark again.
Now, the boot logo is showing for an even briefer amount of time.
I am suspecting the battery or USB port. I don't have parts readily available to swap, however.
It may be worth adding, when I plug in the device, without touching any buttons, the screen starts flashing the Samsung Galaxy Tab 4 boot logo. I would guess a stuck power button, but the power button travels freely. When I unplug the tablet from the computer, the flashing stops.
Trying to boot it with power + volume up garners no response from the device.
Any ideas?
Having same issue here
Tried hard reset, no dice.
Tried opening the back to see if I can identify some loose connection, didn't see anything funny. I am not an electrician.
My sister's having the same issue with her T230NU. It still boots (it'll boot to the Samsung splash, but then it flashes off the screen in half a second; this repeats every 7 seconds), but only if it's plugged directly to the wall charger. She let it sit overnight to charge, and it's still got this issue. I'm pretty sure her battery was drained when the issue started occurring last night, but it doesn't look like the battery has charged much (if at all) since then.

S7 EDGE Won't boot up

SOLVED
Apparently I had to let it charge for a whole hour, seems like it was completely drained somehow or something. Close the thread please.
Guys yesterday night my phone had 20% battery, in the morning it must have ran out of battery. But when I tried turning it on it wouldn't. I connected it to the charger it showed the chargin screen but without percentage. Tried turning it on but it still would not.
Tried booting in bootloader mode which it did. But after I restarted it, it stopped charging too.
So right now my phone wont boot up from power menu.
It wont boot to recovery using vol up + home + power
It wont boot to bootloader using vol down + home + power.
And when I plug it to the charger it wont show any signs of charging, no led no charge screen. nothing.
Help me android gurus.
(It's the international version with the exynos rooted)
Try With Different Charger (preferable 2 amp)
