[Q] Problems loading stock radio and recovery
I got myself into trouble and I hope that someone who knows more than me can answer two questions.
I bought a new Nexus 7 2013 WIFI (razor / flo). I loaded TWRP recovery, and rooted the device. I decided to encrypt the drive, but TWRP doesn't appear able to do that (when the device reboots to start encryption, it just boots normally into Android). However it does appear that TWRP can mount an encrypted drive, so I decided to flash stock recovery to do the encryption and then reflash with TWRP.
I accidentally flashed with the wrong stock image. I used the image for the Nexus 7 2013 Mobile (razorg / deb). The flash-all.sh script includes a step for flashing the radio (fastboot flash radio radio-deb-deb-g00_2.37.0_1024.img). It executed the command without error, but I don't think there is a radio partition on this device. Does anyone know if there is a radio partition to control the GPS, WIFI, and/or NFC? Should I do something to undo this problem? I cannot find a radio firmware for this device, and the WIFI and GPS appear to work fine so perhaps I should just move on.
Even when I use the stock recovery image for the correct device, it does not appear to load correctly. fastboot runs without errors, but when I boot into recovery I get the unconscious android with the red exclamation in his tummy. I have done a full wipe of all partitions, and a full restore. Based on my search in the forums, this appears to be a common problem but the suggested solutions don't seem to apply to my device. Any suggestions?
I should note that re-installing TRWP works fine, and I was able to restore my data from a backup. But I can't encrypt the device or install future updates until I can roll back to the stock restore image.
Thank you in advance for your help.
