The Service Tag is referring to 5520 not 5420, is that correct?
Also the Motherboard Number and the Dump file is for 5520.

Your file can't be repaired, it should a lot of errors in ME Analyzer. Are you sure it's the Original BIOS?
I will attach a file which is for the same machine, perhaps it can help you.

Hi,
I have Dell Latitude 5520
Service tag: 29MCY93
EX: 4935316071
I lost the original bios bin, I used the bin from #5 post, and it boot up to bios, after I input service tag, saved and exit, it boot again and I pressed alt F to disable manufacture mode. after disable I exit the bios setup and unit has no power again. When I unplug and plug back the power cord, just the front while led on for 2 seconds and off and can't power up.
If I flash the chip again, same thing will happen.
Anyone known what is the issue with it?
Thanks for your time.

Try

Thanks @ Qayyum786,
tried outimage.rar bin, after entered service tag, disable absolute, saved exit, it boot up again, I pressed Alt F to disable manufacturing mode, got to bios again, check everything look good, exit the bios and the laptop has no power again. When unplug and plug back the charger cable, front while led on for around 2 seconds and off, press on power button, no power, no light at front led indicator. Do you have any idea what I did wrong?

Dont remove bios chip and reprogram again. Just heat bios chip and near by resistor related to bios chip and try to power on
bios chip could be malfunction or resistor has only 1 to percent tolerance only
