4-Channel 16-Bit ADC for Raspberry Pi (ADS1115) Address 48 to 49

I was originally using address 48 and everything worked but I have another addition that has to use 48 so I need to change the ADS1115 to address 49. I verified with i2cdetect -y 1 that the ads1115 is on address 49.
i2cdetect -y 1
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: – – – – – – – – – – – – –
10: – – – – – – – – – – – – – – – –
20: – – – – – – – – – – – – – – – –
30: – – – – – – – – – – – – – – – –
40: – – – – – – – – – 49 – – – – – –
50: – – – – – – – – – – – – – – – –
60: – – – – – – – – – – – – – – – –
70: – – – – – – – –

I run the sudo ./install.sh -u
reboot pi.
I run the sudo ./install.sh -u adc_ads1115
sync
reboot pi.
However it just keeps adding the path to /sys/devices/platform/soc/20804000.i2c/i2c-1/1-0048 ?
All of this is without adding the other device yet so nothing has changed other than the physical address mod needed for address 49.
What am I missing ?

Thanks,

There are 4 possible I2C addresses of this grove, from 0x48 to 0x4B. The default I2C address is 0x48. You can change the I2C address by doing some soldering.

If SDA(corresponding address 0x4A) is used as the device address, hold the SDA line low for at least 100 ns after the SCL line goes low to make sure the device decodes the address correctly during I2C communication.
