[EVO 4G General] biank:
This post is explained in plain English for everyone to understand what i did.

After being on this forum for years, i decided to post some information which i haven't found to be explained anywhere in details about some issues that i came across regarding voicemail notification and connecting to a Wireless N network.

If you are one of thous guys that want to use the stock rom, like myself, then you may realize that your Voicemail Notification won't work with 4.24.651.1 version IF you had your phone previously flashed on Boostmobile. Unfortunately i couldn't find any fix for the voicemail notification to work properly, there is a work around for this to work.

Apparently the voicemail notification works perfectly with the Odexed or De-Odexed version 4.22.651.2 which can be downloaded here. I personally tested both of them and the voicemail notification works as it should on my flashed HTC EVO 4G on Bosstmobile.

Now, here is something that you should know. IF you decide to download & upgraded to the stock version 4.24.651.1 Odexed, De-Odexed or from Settings/System updates/HTC software update/

4.24.651.1 your voicemail notification will NOT WORK ANYMORE. Whatever changes are made in 4.24.651.1 through the upgrade process brakes the voicemail notification for flashed evo on boostmobile.

This is only for thous that have an Wireless router that use Wifi N aka 802.11n . If you use B or G router you don't have to read this. This only applies for 802.11n.

Wireless N issues that i came across while trying to connect to my router are as follows:

I have a Belkin N F5D8233-4 router which has 802.11n support and works perfect with all my laptops that use the WiFi N technology but i had issues to connect my evo even before i did any change to this phone. The issue is that when i have selected on my router the b+g+n and the SSID broadcast name is turned off the phone will not connect for nothing. If you really don't want to broadcast your SSID from your router, by changing to 802.11g or in my case "g" with the SSID broadcast turned off the phone will connect without a problem. I personally don't like to use the 802.11g especially because i have to wait long long time to transfer large files on my LAN between pc's. So, after looking into downloading the driver for my evo on 4.22.651.2 version, i installed successfully through the zip file, turned my router back to b+g+n, but again - i couldn't connect. At first i believed that i didn't install properly the Wireless N driver for 4.22.651.2 version, but after i reinstalled couple times, i decided to play with my router.

What i found out is that, if i turn ON the SSID broadcast the HTC EVO 4G will connect successfully at N speeds aka 802.11n. Which means that they way how was the driver coded, it can't connect to an N network without the SSID being broadcast.

As far as the bandwidth frequency i left it at 20Mhz only and everything works as it should.

To check if you're connected at 802.11n speed go to Settings/Wireless & networks/Wi-fi settings/ and click on your network. A window will open, and if you see anything bigger then 54Mbps, then you're using 802.11n speeds.

On the above link you'll also see the "Kernel - HTC#1 and18-2 (may04) w/ Wireless N Enabled" which is the driver for 802.11n that works for me, after going through all these issues on my flashed phone.

I hope this brings some light for thous that still struggle with this type of problems on stock roms.
