I went to Jio Centre and thanks to the warranty they replaced the whole motherboard of the device free of cost. It now uses firmware version PEG_M2_B20
UPDATE : @sydikm shared a firmware file with me which is exactly meant for our JIOFI 2. I will share its in OP. Its version is PEG_M2_B04 All credits to @sydikm
