The fire button only works if a battery is attached to the board, I did it and had my fire button back on. Thread can be closed!

Hello! I have a DNA250 board that I am trying to fix, today doing the debug mode in escribe I found out my Fire button is not working anymore.. I also have a problem because mode show I am in Stealth Mode. I need to exit Stealth mode but my fire button is not working.. Up and down are ok. Is there a method to exit stealth by escribe? I tried pressing Fire with buttons in Device manager togheter with Down on the board but Device manager only detects one source of input.. Thank you in advance for your help!

I admit to having the same doubt as you, but unfortunately I cannot find any information about a BQ76925 24 pin chip (square) that is not RGER or RGET.. Also i really want to work so at least i want to be sure about which of the two i need to order..

Do you by chance know which is the version of the chip? Is it BQ76925RGER or BQ76925RGET? I am trying to get a new chip but at leadt i want to be sure about it, thanks again!

I saw online that there are many types of that chip. I think i can see BQ76925 TI [something unreadable] AXH4 on it but i am not sure. What do you think about the new values of USB power and current? Do you think it could be something other than the chip?

Update: I downgraded to an earlier firmware version (from sp6 to sp5) and ACTUALLY something changed but still not working. Now from the total 0.0000 of usb power and usb current we are at 0.015 (max) W of USB Power and 0.002 A of USB Current but the charge is still dropping. Do you have more information about the Power managment chip or where to find the codes so i can search it online if its the problem? Also, is there a datasheet with electronic schematic that i can consult? Thanks!

I did Device Manager -> Diagnostics -> Enable USB charging many times with no luck! I will try an older firmware. How do you suggest me to see if the BQ76925 chip doesnt work? Thank you!

Hello! Thank you both for your quick replies! I went into a shop and we have welded again the micro usb port but with no luck! The port connections are all good but the situation on device monitor is still the same and the battery still doesnt charge. I will attach the battery section on Mod. Using the multimeter tester, which part of the board do you recommend I check to see where the charge is interrupted? Thank you!

Hello! My name is Riccardo and i have an old DNA250 board that i am trying to recover. The board i think is working ok, it is 5 years old but there are no problems in escribe. I bought a new lipo, 3S 11.1V 1300mAh and 14,43Wh but connecting it to he pc or to a power brick it is not charging. I assume the USB port works fine because eScribe connects to the DNA, and the T-Plug connections works too because the battery gets readed on too. I checked the Fuse continuity and it's 0.0 so the fuse is good. What can i test with the multimeter to see where is the problem? Many thanks in advance!
