Hi Lapfix, first of all, thank you very much for your help!
I've performed both the BIOS reading and flashing without a charger connected, without the CMOS battery connected, without a battery, and
even with and without RAM installed. I've tried multiple methods, and the same thing happened every time. I press the power button.
The button lights up for a couple of seconds, then it turns off and won't boot. I've also tried the dump Hoaca provided me in post #36 again, as you mentioned. I even tried the dump you provided me again just in case.
It might have flashed incorrectly for some reason, but nothing worked. I've checked all the connections on the board, but everything is fine, and I don't think it caused a short circuit because I've always taken precautions and grounded myself with a wrist strap to avoid static discharge. Honestly, I'm a little worried and frustrated. The only thing I haven't tried is the exact 30 seconds, but I have been holding the button for several seconds, but it hasn't worked. It always does the same thing: the button lights up, then turns off after a couple of seconds, and nothing. Honestly, it's very frustrating...

Well, I waited the 30 seconds and nothing, the PC is dead, I'm starting to think that I have no solution, in addition, only the As programmer 2.1. 2 program is the only one that searching for the XMC25RH256C chip lets me do a dump and flash, I tried the Hoaca dump again and it didn't work, after doing the flashing, it decided to check the flash verification and it gave me a data verification error, but the flashing was done correctly, I'm starting to think that I don't know if the original reading I did is correct since I haven't been able to do any other readings, I don't flash with other versions of programs or with As programmer or with Neo programmer since they don't have this BIOS chip XMC25RH256C in the database and I'm not sure if the verification should not give any errors, I flashed again and the flashing was done correctly but the verification gave me a reading error, I tried with another programmer CH341a that I have it and the same thing; flashing is fine, but verification gives an error when reading, so I don't know what else to do. I hope you can give me a solution...

Well, I finally got it thanks to you all. I want to thank each and every one of you; Hoaca388, lapfix, danito, and especially SMDflea, who has been very patient with me. In general, thank you all for taking the time to answer my questions and helping me. The problem I was having was a flashing error. I tried several times, but it turned out it wasn't done correctly. Finally, with one of your clean images, it worked. Thanks again to all of you, and I hope to continue learning a little more with your help. A big hug, and see you soon!
