Devo 7E not working after upgrading firmware was created by is fpv
Hi All, I'm really need help. I just wondering if there is any solution to fix my devo 7e. I just bought it last month, upgrade to the latest nightly build last week, after the program update successful to my devo 7e. it suddenly turn off.. now it I cant even switch it on.. try to enter programming and USB mode also nothing happen like there is no power at all.. I have multimeter but the board seem nothing damage not even have burn smell. does anyone have been this situation before? is there any solution to fixed this?
I only mod the bypass diode and added 3 position switch to my devo 7e. others still in normal and still using AA battery for power supply.

Walkera Dfuse V2.31 can't damage bootloader, so it looks like you have hardware problem.

hi, i don't know if you solved it, it's been a while since the last post.
cmq I try to tell you lamia even if I'm not an expert.
I don't think the firmware upgrade could have damaged everything and not even make it turn on. I think you considered charging the battery, right? at this point have you tried to enter usb mode?
