Raspberry PI stopped working

[doctorlove5295]

I bought a raspberry pi more than two months ago, and I have been using it without a problem this entire time. I set up script that once a week, the pi updates and then reboots, which was working for a few weeks. However, this last time, I was not able to access the pi at all. I checked to see if the Ethernet light was on, and it was not. Only the red light turns on. I have tried plugging it into a hdmi, and it did not boot. If I am right, the issue is there is a red light, but no green light flashing:

What I have tried so far:
check if files exist: before reformatting, those files did exist, i did replace bootcode.bin as recommended on the wiki, Did not boot.
check power supply: 5V 2000 mA
hardware abuse: I have not connected the pi to anything other than its power supply; I think this is unlikely
format sd card: format as fat32, downloaded noobs, and placed files into sd card. Did not boot, same issue
reformat sd card: format as fat32, downloaded raspbian image, wrote image to sd card. Did not boot, same issue.
add config.txt file: In the root directory of sd card, I added a config file with hdmi_safe=1. DId not boot, same issue.
use keyboard to press 1-4: tried each button, nothing came up on the display, which I assume means it did not boot.

What i have yet to try:
different sd card: i bought a starter kit that came with an 8-gb sd card with noobs on it. It seems the brand is "V-data", which I cant find on the rpi known sd cards page. I dont have any other sd cards on hand at the moment. Could this be a problem, even if it was working perfectly fine the past few weeks? While they are cheap, I do not want to buy another sd card if the same problem is going to occur again: that'd be a waste.
sd card pins: I checked and noticed that one of the pins is slightly lower than the rest. I will try this later today and see if I can raise it when I get the tools, but is it possible that the pin could retract after again, it was working fine up until now?

Thank you for any help. I will update accordingly whenever I try something.

It seems like the OS is not booting probably because of a bent SD card or one pin is lower than the other (as you suggest). If it does not work with a new SD card that has been installed with the latest version of NOOBS, get a replacement from your supplier.

We tried fixing the pins, and there was still no success.

I tried my last option and ended up buying an sd card and it finally worked. It seems that the sd card I initially had is no longer bootable.

Thanks for the help!
