Fastboot rom - original LG rom

---

Can someone tell me what was changed in fastboot file?
I attach both: original and fastboot file from KDZ.
Since I can use only fastboot ROM, I ask anyone on this forum , to tell me difference between those two files. why my phone block on LG logo when is used original file, but when I change to fastboot file, it works normal.
Thanks

P.S It is obvious: that someone can unpack those files, make modification, and pack it again.

When Kdz gets extracted it goes to cab then dz then mbn.
Mbn files are the whole system
For recovery and fastboot all you need to do is delete appsboot_fast.mbn

Somebody can open MBN files and change it. And pack it again. I didn't ask what files I need to delete, I ask, what is difference between those two files.
If you use any original ROM, and change with fastboot file, you got fastboot rom, but that was not my question.

One contains the code for fastboot mode and one does not... I don't know how else to put it.

That is so obvious
I ask myself and all other: why my phone can work with any fastboot ROM, but cannot with normal rom.
Since all difference is in those two files.
For some reason after first flash with fastboot rom, the only rom I can use is fastboot rom. So what was changed in memory of my mobile phone with fastboot code?
And of course how to revert those changes.
If you say that nothing cannot be changed, I will ask you again: why then my phone only works with fastboot roms?

I don't know what's different about your phone but I've definitely flashed a stock (Europe Open v20B) 2.1 rom over a fastboot rom and the phone booted fine (I was new at this then, so I thought fastboot would still be there but it wasn't)

So my phone is mistery: but as I can see, many others have also same problem: so in time, someone will provide fix for that ( I hope)

I have the same problem. My phone boot only with fastboot roms and the latest open Europe i found is V20A. At least can anyone make a fastboot V20B or tell me if there is already.

Try using this. The program has the option to remove fastboot and recovery, if that's what you want. I've never tried it, but it might work for you. Flash a fastboot rom, try it and share results.
