People always asking again and again on flashing ROMs, Recovery, GApps, Root etc. So, I have made detailed step by step guide for this. Hope now it will be clear to everyone for these processes:

BEFORE YOU DO ANYTHING FROM FOLLOWING, PLEASE MAKE ANANDROID BACKUP, BEST WITH TWRP!!!​

BECAUSE TWRP CAN MAKE BACKUP INCLUDING PRESIST AND MODEMST PARTITIONS!!![/CENTER]

GUIDE TO FLASH STOCK ROM:

NOTE:

1. Be sure to backup all important data (contacts, messages, call records, etc.) before proceeding

2. Ensure that Phone Battery is at least 40%.

3. Downloaded required STOCK ROM.

4. Phone with Stock Recovery.

STEPS:

1. Copy the downloaded zipped STOCK ROM to the root directory of External SD card or Internal SD card.

2. Power-off the phone.

3. Put the phone in the Recovery Mode and for this you need to press Vol+ and Power button at the same time for few secs and then release the Power Button.

4. In the Stock Recovery, perform wipe data/factory reset and wipe cache partition (In the menu, use +/- volume keys to scroll up/down & power button for confirmation).

5. Depending on which SD card you have copied the zipped STOCK ROM, choose "Apply update from /sdcard" or "Apply update from external /sdcard" accordingly.

6. Select the zipped STOCK ROM to flash.

7. Wait until you get the confirmation of successful flashing.

8. Reboot the phone by selecting "reboot system now".

9. DONE. (Initial boot may take some time so have patience.)
