MacBook Pro 15 inches A1990 Described as STUCK ON DFU MODE.
In this repair, the repair company told us that they had tried to restore/revive the device from DFU, bit would not work, we also tried to REVIVE the device, but returned with error 6, which suggests an issue with the SSD circuitry, there we found a short to ground on the 2.5V line to the NAND, we resolved it and again performed the REVIVE , and this time it was successful.
