[Nook Touch General] nmyshkin:
OK, so I'm glad you asked this question because it prompted me to look more closely at the kernal issue and I found that there

is

an appropriate kernal for the Glowlight!

CAUTION: before you do this, use NookManager to make a backup of your device.

For audio

playback

:

You will need a CWM card to flash the zip. You can make a card from one of the two files at: https://xdaforums.com/t/nst-cwr-rc2-clockworkmod-based-recovery-fixed-backup-issue.1360994/. There is a "2 gb" file and one for "128 gb". The card you choose should have at least the capacity mentioned in the file name. Download the file, unzip and burn the image to an SDcard. DO NOT try to install CWM directly onto your device. This will destroy the one fail-safe that makes the NST so hard to kill: the factory image.

Next, download the CWM-flashable USB Audio zip from here: https://xdaforums.com/t/cwm-usb-audio-enabler.3139603/

The kernal in this zip is based on 1.2.x so it will work with a Glowlight. It includes multitouch, enables FastMode (with the appropriate app), and USBHost. It is overclocked, so you may want to install some kind of CPU regulator to calm it down. It will

not

work with the NoRefresh app.

If you would prefer a kernal that is not overclocked and works with NoRefresh (but not FastMode), you can download the zips here: https://xdaforums.com/t/nstg-kernel-multitouch-usb-host-kernel.2846867/#post-54803848. Unzip the files.

Open

(not unzip) the CWM-flashable USB Audio zip and inspect the contents (WinRAR allows this kind of thing, not sure about other archiving software). In the "boot" folder you will find the two kernal files. Drag the replacement files you downloaded into this folder (within the archive) and set the overwrite to "storage" or "store". You don't want any more compression going on. Then close the archive.

Once you have the CWM-flashable zip set up the way you want it, copy it to the CWM card. Power down the NSTG, insert the CWM card, power up and wait for completion of boot. This is the button function layout for CWM:

Button layout:

Both Buttons on the left: BACK

Upper button on the right: UP

Lower button on the right: DOWN

n button: SELECT

Power button: TOGGLE DISPLAY

Once you've flashed the zip, you'll need to reboot. If there is a message about possibly losing root, etc., just say

no

. I've been down that road before.... By attempting to fix a non-existent problem it will create that very problem. So don't let it "fix" nothing.

You need some hardware to make all of these changes actually do something. Also a little software. As far as the hardware, you need an OTG cable (e.g. https://www.ebay.com/itm/Micro-USB-...48?hash=item365c5af32c:g:LmEAAOSwa6heLwTo)and a USB-C audio thingy (e.g. https://www.ebay.com/p/94253551?iid=383621510193 or https://www.ebay.com/itm/Sabrent-Us...259335?hash=item42166fae07:g:v~kAAOSwG5ZekgAB). Both are available on ebay or Amazon and are not expensive. Some audio gizmos include volume control buttons, some don't. I have one of each, but don't use the one with the buttons because it's full of LEDs and the whole USB Host thing drains power anyway, so who needs a bunch of lights?

Some people have had issues with USB Host. I suspect it's because of the OTG cables. The first one I got just did not work. The USB socket on the NSTG is not exactly an industry standard and the cheap OTG cables are not precision instruments. I finally got one that fits well but I have another (right-angle model) which sticks out half-way when fully inserted. It works, but it's worrisome. Also, do not let the cable and audio gizmo dangle. Everything should be on a flat surface. If you put stress on the USB jack and make it unhappy, you're going to have trouble doing something very important: charging. I speak from experience.

Now the software. To activate USB Host (and Audio) you need one or two apps. @Renate NST has a USB Host app as well as an Audio Control app. Both are needed for Audio and are useful if you need to troubleshoot. They can be downloaded from her signature link.

I have found that with a good OTG cable I never have initialization issues with USB Host (on all three devices I own). So I wrote a little one-touch toggle app to turn USB Audio on and off. There are screen prompts to tell you when to connect and disconnect things. Version 4 of the app displays on-screen volume controls as well. You can find that here: https://xdaforums.com/t/app-nst-g-usb-one-touch-toggles.3172213/. The same functionality is also built in to my QuickTiles app, although with nicer screen prompts :)

If you get this working and are interested in audio

recording

with the NSTG, there are a few more things to do, but we'll leave that alone for now.
