M8 is broken?

[ambiente1]

Hey folks!

A friend of mine sent me his smartphone to repair but i'm sitting in a corner right now...

I never had a HTC before, not in my hands, not received by any other person - first try so far.

Here's the situation:
The battery from the smartphone was empty over a night.
Next day, when he want to start - it doesn't start and runs into bootloader.
He tried some things i think, but isn't really familiar with that.

The phone said in bootloader:
*** Software status: Modified ***
*** UNLOCKED ***
S-ON

For now i followed this tutorial "htc-one.wonderhowto.com/how-to/unlock-bootloader-root-your-htc-one-m8-0154444/".

I already received the "Unlock_code.bin" and uploaded to the phone - seems working, because it says "Unlocked".
After that i flashed the "openrecovery-twrp-2.7.0.2-m8.img" - seems working, because it says "OKAY".
Than, i erased the cache, try to enter recovery, but it returns immediately to bootloader. :crying:

What i've done wrong?

Any hints what happens with the phone? How can i restore to stock easily?
He don't need special tools or anything else, just a working phone so far

That recovery version is very outdated. You were using an old tutorial.
If it were me, I'd find an RUU to run. What do you get from fastboot getvar version-main? Or better yet, post the results of fastboot getvar all minus the IMEI and serial#, and someone can direct you to the proper RUU

There's your problem. You don't have the M8. You have the M8S. The M8 recovery won't work on that.
The M8S has a separate forum here, and you can find the proper TWRP recovery for it in this thread.
You do have very old firmware though. Hopefully that recovery version will work as it is made for newer firmware. I think it will.
