FASTBOOT METHOD OF RECOVERY TO FIX ALL ISSUES IN YOUR PHONE AND RESTORE IT TO FACTORY STATE

Hola Friends,

First things first. If you are not a Xiaomi Redmi 1s user, this post is not for you. I couldn't include that part to the title due to obvious reasons.

When will you need this?

1. If you found some issue in one rom that keeps occurring in future ROMs as well, look no further, this is for you.
2. If your phone is on a custom ROM and it has so many issues that need fixing
3. If you want to get the phone back to factory state in all aspects

 Note that using this method will re install all the basic stuff such as audio drivers etc

Stuff you will need

1. A PC - we are gonna be doing the flashing via pc
2. Fastboot rom - note that the fastboot rom is not the same as the other normal ROM zip file that you use to flash via custom recovery. Fastboot ROMs are larger in size and can be found here
3. Minimal adb fastboot set up  from here
4. A .tar file extractor like Peazip from here to initially extract the fastboot rom and another one like 7-zip here to extract the initially extracted file.

Obviously you will need to have a Redmi 1s  that can boot to fastboot mode which we will talk about later and a usb cable and the phone should be charged to atleast 60%.

PROCEDURE

We need to first setup adb. For this, install the Minimal adb fastboot that you downloaded in 3.After that right click on My Computer and click on properties. The on the left hand side, click on Advanced system settings. Then in that box at the bottom, click on Environment Variables. Inside this, under system variables, scroll down to path. Click on it and then click on edit.To the end of the text, add
;C:\Program Files (x86)\Minimal ADB and Fastboot 
if you have a 64bit OS or
C:\Program Files \Minimal ADB and Fastboot
if you have a 32 bit OS.
ADB is now ready. 
Follow the steps below 

1. Extract FASTBOOT ROM in "Drive C:" using Peazip

2. Extract this file you obtain with 7zip.

3. Open this folder and the folder inside it and copy this address(ctrl+c)

3. Right Click on "Computer" -> Go To Properties -> Then Advanced System Settings

Click on environment variables

click on temp in the user variables section and path in the System variable section and then click on edit

click in the variable value box and to the end of the text , add a ; and then paste the text copied in step 3 here. Click on OK.

4. Close everything and open My Computer > C and navigate to the place where we extracted the fastboot rom. The address will be something like C:\armani_global_images_JHCMIBL50.0_4\armani_global_images_JHCMIBL50.0_4.3_in

Here there will be 3 .bat files namely 

1. Flash_All 

2.Flash_all_except_data_stroage 

3.Flash_all_except_storage

Boot your phone in fastboot mode by pressing and holding Power button+Volume down button after switching off the phone.

Next double click on one of the three options you saw above

I would recommend you to go with the first option(flash_all.bat)

Wait until the the process completes and the phone will automatically boot after the procedure is complete.

ENJOY YOUR REDMI 1S IN IT'S BRAND NEW STATE!!! :D
