This is how you enable OPDS

[electronicfur]

I did the changes in ebrmain as described in the OP, which then did enable the "Network Libraries".

To test the syncing to /var/run/device.cfg I then changed the /mnt/secure/device.cfg and /mnt/secure/device.cfg.back to have "have_opds=0". Rebooted.

After reboot /var/run/device.cfg now also has "have_opds=0" but "Network Libraries" still enabled...

Strangely it's the opposite for me, both files in /ebrmain/config have have_opds=0 and /mnt/secure set to have_opds=1 and it works!

Thanks for that info, really useful feedback. The people at Pocketbook have definitely been tinkering in the newest FW revisions!

Glad you have it working for yourself at least...
now you can work on the COPS catalog for your son!

[electronicfur]

Thanks for your help. Odd that it works opposite for you. If you need me to do anymore testing to figure stuff out let me know.

I also figured out the issue with the COPS Calibre OPDS feed and the Android Pocketbook, just in case anyone else runs into this. It's an OPDS feed validation error and there's a patch on a newer fork of COPS Calibre by Mikespub.

Also kudos to all those who worked on the JailBreak and Services. Didn't realise it would be so straightforward.

Got it working on FW 6.8.2676-U-W without ssh with root (I'm a Windows user).
There are a some files in /ebrmain that are not in a compressed read-only rom image - cramfs. All of /ebrmain/config/*.* are outside the cramfs loop:

/ebrmain/config:
-rw-r--r-- 1 280 Dec 5 11:15 desktop_apps.cfg
lrwxrwxrwx 1 30 Dec 13 18:02 device.cfg -> /ebrmain/config/device.cfg.gen
-rw-r--r-- 1 450 Dec 13 18:02 device.cfg.gen
-rw-r--r-- 1 1.7K Dec 5 11:15 extensions.cfg
lrwxrwxrwx 1 30 Dec 13 18:02 global.cfg -> /ebrmain/config/global.cfg.gen
-rw-r--r-- 1 2.0K Dec 13 18:02 global.cfg.gen
lrwxrwxrwx 1 31 Dec 13 18:02 rsslist.cfg -> /ebrmain/config/rsslist.cfg.gen
-rw-r--r-- 1 2.3K Dec 13 18:02 rsslist.cfg.gen

Steps:
1) Copy /ebrmain/config/device.cfg.gen /mnt/ext1/device.cfg.gen and change the line:

have_opds=0

to

have_opds=1

2) Run a small script which needs root and basically does (outside a lot of backup and logging):
2.1) remount /ebrmain to rw
2.2) set permission for /ebrmain/config/device.cfg.gen to rw-rw-rw
2.3) copy changed device.cfg.gen from mnt/ext1 back to /ebrmain/config/device.cfg.gen
2.4) changes permission back and remounts /ebrmain to ro back.

#!/bin/sh
logname="/mnt/ext1/OPDS_install.log"
/mnt/secure/su mount -o rw,remount /ebrmain > $logname
/mnt/secure/su cp -f /ebrmain/config/device.cfg.gen /mnt/ext1/device.cfg.gen.org >> $logname
/mnt/secure/su stat -c "%a" /ebrmain/config/device.cfg.gen >> $logname
/mnt/secure/su chmod 666 /ebrmain/config/device.cfg.gen >> $logname
/mnt/secure/su stat -c "%a" /ebrmain/config/device.cfg.gen >> $logname
/mnt/secure/su cp -f /mnt/ext1/device.cfg.gen /ebrmain/config >> $logname
/mnt/secure/su chmod 644 /ebrmain/config/device.cfg.gen >> $logname
/mnt/secure/su stat -c "%a" /ebrmain/config/device.cfg.gen >> $logname
/mnt/secure/su mount -o ro,remount /ebrmain >> $logname
exit

Thanks to all who have helped.

Nice work nhedgehog!
More convenient than ssh and nano.

Presume this is a mistype though:
/mnt/secure/su cp -f /ebrmain/config/device.cfg.gen /mnt/ext1/device.cfg.gen.org >> $logname

FYI... ssh from the Windows command prompt is easy, just type: ssh root@ip-adress
(Grab the IP address from the "Rooted device settings" section.)

[neil_swann80]

Made it completely autonomous...

FYI.. the script below is just a simpler method for rooted/jailbroken devices. Save the code as a .app file in /mnt/ext1/applications to run.
If you're NOT rooted or can't root try THIS

#!/bin/sh

# needs root!
udo=/mnt/secure/su

rm -f /mnt/ext1/device.cfg.gen
IFS=''; cat "/ebrmain/config/device.cfg.gen" |
while read data; do
	if echo "$data" | grep -q "have_opds=0"; then 
		echo "have_opds=1" >> "/mnt/ext1/device.cfg.gen"
    else echo "${data}" >> "/mnt/ext1/device.cfg.gen"; fi
done

$udo mount -o rw,remount /ebrmain
$udo chmod 666 /ebrmain/config/device.cfg.gen
$udo cp -f /mnt/ext1/device.cfg.gen /ebrmain/config
$udo chmod 644 /ebrmain/config/device.cfg.gen
$udo mount -o ro,remount /ebrmain

rm -f /mnt/ext1/device.cfg.gen

exit

[nhedgehog]

Thanks, much better than my half-automatic attempt. I just reset my device to:
have_opds=0
and run your script and everything was working fine.

Apologies for the late reply, but I've been busy with work lately. Root worked first time on my reader, but apparently the good folks here have found a way to make it work without root, so you might be in luck.

@JSWolf I'll test it and post my findings

Confirmed. I tested by downloading an acsm file from Adobe's very own digital editions sample ebook library and ended up with an epub version of the book.

Could somebody test the attached installer? It works perfectly on my rooted device, some unrooted feedback would be great.

Theoretically it should work on an unrooted device as it uses ezdiy's root permission exploit.
(If the attached installer fails for you, try the old one from HERE)

Install instructions:

Spoiler:

Upload the attached file to the root directory of your device storage (/mnt/ext1) and rename it without the .zip extension, e.g. EnableOPDS_v4.pbi

After unplugging the USB (or a reboot) open the Library, select "Formats" from the drop-down menu, then select "PBI". Click on EnableOPDS_v4 and choose install then wait for the confirmation/fail dialog. If successful the device will reboot.

Once rebooted, check if "Network Libraries" is now available in the Library drop-down menu.

FYI: Some OPDS catalogs are listed in the wiki HERE
(Click on the links first to test, if you don't see xml they're defunct.)

EDIT: Added success/fail dialog. Should now only reboot on success. Running the installer again will give you the option to disable OPDS.
EDIT2: Fixed an error preventing failure message display. Tidied code up too.

[nhedgehog]

And finally the "Ezdiy method"!
Just to test I reset my opds entry, removed jailbreak and tested it.

Success!
Nice one, working fine! Though adding an uninstaller into the installer would complete the package.

Edit: One thing regarding the use of pbi-installer files should be considered too:
Every installer is getting an entry in:
/mnt/secure/pbpk/
like:
enableopds_p1.fop
enableopds_p1.inf
enableopds_p1.inf.back
enableopds_p2.fop
enableopds_p2.inf
enableopds_p2.inf.back
enableopds_v3.fop
enableopds_v3.inf
enableopds_v3.inf.back

[neil_swann80]

Interesting. What are the default permissions for /mnt/secure/pbpk?
I've changed mine without noting the original.

[nhedgehog]

Custom installer seems to leave those artifacts open to all compared to the PB installer:

drwxrwx--- 2 3.0K Mar 4 17:19 pbpk

/mnt/secure/pbpk:
drwxrwx--- 2 3.0K Mar 4 17:19 .

[neil_swann80]

770, thanks. I'll leave it as 775 whilst I continue testing.

FYI... I think setting destNofop=1 within _scriptInstall is preventing these log files from being created. Cleared pbpk and ran a couple of installers with and without this entry and so far it holds up.

I wonder if there's also an entry for setting initial permissions? destProtect maybe?
I figure there must also be a setting to auto-delete the installer on completion.

Seems like the .fop files contain a log of the files installed and the .inf is a copy of the _scriptInstall parameters.

I've updated the installer above to now uninstall. Seems to work. Also added nofop line.

On a non-rooted Era with firmware 6.8.3246 - it works!
