New Nook Glowlight 4? - Page 35

token_01 · 02-15-2023, 06:23 AM

adb: error: failed to copy 'Vendor_0001_Product_0001.kl' to '/system/usr/keylayout/Vendor_0001_Product_0001.kl': remote couldn't create file: Read-only file system

Any solution to the above?

adb root simply does not work:
"adbd cannot run as root in production builds"

Only want to enable use of the page buttons while using Librera, broken since the recent update.

Probably too many solutions.

If you use Magisk you can make a Magisk module to replace /system/usr/keylayout/Vendor_0001_Product_0001.kl
If you have NeoNoogie as recovery, mount /system r/w and replace the file (best to make a full backup of /system in case of some verification).
You could modify the kernel so that the VID/PID of the buttons is not 0001/0001. Then you could put the keylayout in /data/system/devices/keylayout/ which is writeable (but requires root).
You could patch the reading app to use whatever codes the buttons generate

I have no idea how to make a Magisk module. Is there a step by step guide for simpletons?

Same for kernel modification.

Any help is appreciated.

Making a Magisk module just for yourself (vs. for distribution) is easy.
You need to create two files on your desktop and adb push to sdcard.
The first is module.prop

Code:

id=Pointless
name=Pointless
version=1
versionCode=1
author=Me
description=Pointless

"Pointless" is the name, can be anything that you like.
The second is your keylayout.

Code:

key 116  POWER
key 102  HOME

key 191  APP_SWITCH  # top left
key 192  PAGE_UP     # top right
key 193  BACK        # bottom left
key 194  PAGE_DOWN   # bottom right

Or whatever...

Code:

# cd /data/adb/modules
# mkdir Pointless
# cd Pointless
# cp /sdcard/module.prop .
# mkdir -p system/usr/keylayout
# cd system/usr/keylayout
# cp /sdcard/Vendor_0001_Product_0001.kl .
# reboot

See: https://topjohnwu.github.io/Magisk/guides.html

Neo Noogie it is...

(I'm about to chuck this stupid device in the trash, get a damn Kobo Libra 2 like I should have done)

The above doesn't seem to work or isn't clear enough for me.

the system/usr/keylayout is not the pre-existing folders?

How does one install Neo Noogie in 2023? The website is scant and xda is full of people with issues.

fastboot boot nnglow4.img does not work (of course)

B&N ruined the nomenclature.
The Glow with the USB Type C connector uses nnglow21.img
The 7.8" Glow uses nnglow4.img
Or check your BNRV number.

Code:

fastboot flash recovery nnglow~.img
fastboot reboot
adb reboot recovery

In the instructions above you're already in /data/adb/modules/Pointless.
You're creating system/usr/keylayout under that, i.e.
/data/adb/modules/Pointless/system/usr/keylayout
If mkdir -p doesn't work, just do it step by step.

Code:

mkdir system
cd system
mkdir etc
cd etc
mkdir keylayout
cd keylayout

Thank you, I renamed something I shouldn't have, it now works as it should.

Many thanks for your assistance and patience.

Unless Nook firmware updates matter to you, Renate can also help you keep your GL 4 from updating in the future, so you won't have to redo your setup every time there's an update. That's what I've done.

token_01 · 02-15-2023, 11:38 PM

Great, how do I do that?

I'll check out what you told me to do and get back to you! If it's not on this forum, it might be in a private message you sent me here or a post on XDA.

token_01 · 02-17-2023, 02:15 PM

Also, is there a way to change the screensaver from the generic crap that B&N saddled this device with?

downeaster59 · 02-17-2023, 03:09 PM

@Renate: I remember asking you about blocking Nook firmware updates and that you responded, but I can't find this in this forum or on XDA (including private messages). Maybe it was in a different forum? I'll look some more.

I haven't played around with the screensaver at all, so I'm not sure about how to change it, but I am confident that it can be changed.
