CWM not able to read external sd card while installing a new rom

Hi,
I am using redmi 1s with clockworkmod recovery. i tried to install cm12.1 latest version. i wiped the previous rom and tried to install the new rom which is in the external sd card but the cwm is not opening the external sd card, it is not doing anything, it is just stuck there for hours

Wifi not scanning (plz read the whole thread)

I have a in focus m2 3g
I had used exposed modules like GB WiFi was working fine
After couple of weeks my WiFi won't scan also I did scan sometimes
And whenever I used to turn on WiFi screen used to go black
I tried reset ...it worked for like 10min then I faced the same issue
I also tried flashing now the WiFi doesn't scan ....actually it does scans but the screen going black frequency has been reduced
According to me it ain't a hardware issue
Experts plz help me fix this
Thnx

SD Card can not read

1st problem:
After I upgrade to Marshmallow, I'd like to format my sd card, but suddenly i hit the "FORGET" button. can i restore the setting without any root or any methods?

2nd problem:
when i plug the phone to laptop, the Internal Memory won't read too,i should change to PTP instead MTP to detect the internal memory. and I'm already installed the driver via AdbInstaller.

need your help ASAP,Thanks.

Disable OTA - Keep SDCard Write Access and Use a Different Launcher *READ BEFORE BOOT

This must be done before the first time you connect to Wifi or you will likely receive the update that will "fix" the two features in the title. I purchased a second Fire to determine what it would take to disable the initial OTA. At no time connect to Wifi until all this is complete!

The steps are basically as follows:

Boot the fire the first time and bypass the setup.

Enable ADB by going to Settings> Device Options. Keep tapping on the Serial Number field until the Developer options field appears.

Under Developer options Enable ADB

Hook the Fire up to your computer and do the following commands:

adb shell pm hide com.amazon.otaverifier
adb shell pm hide com.amazon.device.software.ota
adb shell pm hide com.amazon.settings.systemupdates

I don't know which of three is the magic one, But you can not longer go to device options > system update. It also never appears to pull down the update in the background. I've rebooted multiple times and used the tablet on wifi with no update to 5.0.1.

This will work on a fresh out of the box tablet but once updated, well you've got to wait for other more talented people to figure out how to get root.
