2G reception issue for refurbished mobile

I bought a refurbished Xiaomi Redmi Mi 4i Duos phone on ebay. Unfortunately, when I tried it out, I found that I was not getting coverage indoors. Checking signal levels, found that 3G and 4G signal levels were OK, but the new phone was having a 20dB loss in signal for 2G signals. Ebay made the seller accept the item back, and refunded me (though I would have preferred a replacement.)




Edit - added the screenshot of an Mi3 at the same location, with better signal, below. -81 dBm as against -101 dBm for the refurbished phone above. 20 dB greater.

accessing archived emails from old CPanel server

A server with WHM and CPanel was being migrated, and I got the query  
Can you tell me how to copy the old emails from the old server before they shut it down?

Inside the cpbackups folder, there are the backups of each site. So, if you want the emails from sitename site for example, you can open the folder

/backup/cpbackup/weekly/sitename/homedir/mail

The archived emails will be in the archive subfolder. They are likely to be in the maildir format - 

Wikipedia has a list of e-mail readers that can directly read e-mail in that format -

wavelab loudness normalization - recommended settings

I had earlier given the recommended settings for SoundForge. A request from A, if I could send him recommended settings for wavelab -



I would recommend the following (this is for radio broadcast):

1. Save each section which has a specific loudness as a separate file - for example announcements with music as a separate file, parts with only talking as a separate file, song as a separate file.

2. Normalize each file with the settings below, and then stitch them together to make the final file.

3. Settings - 

Loudness to achieve = -12 LUFS
Reference: Loudness of entire file
Remove DC offset (checked)
Max peak level = -0.1 dB
Softness 0
Other values no change from the screenshot.
