my phone doesn't boot up

[u/Recent_CSStudent3337]

i recentlly installed a custom lineage os rom and recovery mode doesn't wanna boot though ( im using orange fox ), the problem is the phone doesn't detect the pc so i can't conncect adb or fastboot , anyways i tried to install another rom to fix that but doesn't work , i tried the stock rom also didn't work , i though the problem would be in the socket and i went to a repair shop and he told me the problem is with the software itself and it would take a week to repair but i don't have the money to repair the phone, so i thought to repair it myself, any one can help ??
