Why do want to do that? It will surely not fix the rSAP issue.

Apart from that it should be no problem to build a new file. It will take some time, because you'll have to prepare a Linux (Mac?) machine for compilation and then get the whole Android source tree.

Can anybody share a link, or explain how to downgrade the radio image on 4.4.4 to have it working with rSAP again?
Thank you very much.

See here ... s-t2514095 for a list of all Nexus 5 radio images. The link at the top also contains zip files which can be flashed with a custom recovery. Flashing should make rSAP work again.

The other possibility is to flash the img file in "fastboot" mode, which is a bit more complicated.

Hello admin & all,

I just by chance saw that there is another radio SW on the xda web site.

LPV79 (L Preview)
QUALCOMM Incorporated May 7 2014

Did anybody try this already with regrads to rSAP? Anybody knows if using this L preview radio in combination with the 4.4.4 release incorporates a significant risk to brick the phone???

Just one more observation:

As i unfortunately have been one of the first ones that observed the problem with android 4.4.3 and then downgraded to the 4.4.2 radio to make rsap work again I for a long time skipped the upgrade to 4.4.4.

With Android 4.4.3 and the 4.4.2 radio I obeserved, especially with LTE enabled, often an excessive power drain while the radio was turned off (!). This was also visible in the battery information in the settings menue by the high percentage of the 'phone idle' consumption.

About a week ago I had some time to install 4.4.4., again with the 4.4.2 radio and the effect of high power consumption was gone again.

So if you have still 4.4.3 and also some strange energy loss problems, try 4.4.4.

Hi all,

I recently found that I cannot use my Nexus 5 as mobile hotspot anymore. When I try to activate it, the menu point just shows "Error". I know that I used that function many times in the past, but cannot confirm that this is the case since I use the older baseband on Android 4.4.4.

Could one of you confirm whether mobile hotspot still works in that combination? Would be great.

I have rooted the L-preview, installed the 4.4.2 Radio, but unfortunatly the app cannot find certail system-libs, and is asking if this is a compatible phone. I will try again when the "official" lollipop is availaible an report back.

This is an SELinux problem. If you set it "permissive" everything works. Of course, this is no good solution. I hope I will be able to add the missing permission from within the installer app.
