Hello Vineel,

Once the JTAG is locked viz e-fuse blow on MSP430G2xxx devices, it is permanently locked and cannot be accessed any longer from the JTAG interface. there are no alternative programming methods for this device natively.

G2553 is with UART BSL that can be used for updating firmware. Don't remember if BSL disable option exist on G2553 device. Anyway, you can try BSL mass erase with blank password.

Vineel,

zrno is correct. The G2xx3 are the only G devices with BSL. So you could use UART BSL to re-program the device, but you won't be able to debug.
