Hi  
I am trying to install application on WP76xx but it gets stucked. But if I tried installing the same application on MangOH Yellow(wp76xx) from Airvantage so it succeed.  
Do you think we have to enable the app installation within the module?

Hi  
Yes I am installing helloworld from the airvantage it installs in MangOH but gets stuck when I tried installing WP76xx module  
so we have 2 boards one MangOH with WP76xx and the other one is custom designed WP76xx.  
Do you think we have to enable the app installing feature or anyother?  
Regards

Yes they got the same fw and legato version. i.e. 19.11.2\_4ad011d85a76309438be40fc19e7153a  
legato status : 1 [good] ← current  
Legato framework is running.

if no problem is found in Mangoh WP76xx but only happens in custom board, could this be hardware problem?

Maybe you can downgrade to R12 and then do a factory reset on that problematic module:

It doesn’t shows up as a hardware bug because it connect with Airvantage and configure even reboot as well but when it comes to installing application it stucks.  
Do you think it can be a hardware bug ?  
Thanks

I don’t know, that is why i suggest to do factory reset in R12 on problematic module

Hi  
Reading the logs and From [legato.user](https://docs.legato.io/latest/c_le_avc.html#:~:text=If%20the%20user%20agreement%20is%20not%20accepted%20or,enables%20or%20disables%20user%20agreement%20for%20these%20operations.) I have figured out that it is not accepting the user agreement the error I am reading from the log is `Deferring download for 30 minutes`  
But at the start I was configuring the airvantage from AT and it is only happening on my custom board.  
AT+WDSC=3,1  
AT=WDSC=4,1  
still not fixed.  
thanks @jyijyi
