Thanks

Nobody knows what's happening.

Try again:

1. tell us the version that works for you.
2. tell us the version that gives you an error.
3. tell us the error you're seeing. (copy from crash.log or take a picture of your device while in the crash bomb/don't panic screen)

Thanks for your answer. Finally, I've won. I have had to reinstall all over again. The problem is related to the cache directory. After removing all the items inside, everything works. It's an issue between file versions. Later, I broke all...

Do you have a copy of hackers_reinstall_702.zip?. I've broken my installation, and I have had to reinstall everything...

I've recorded all the process on video. When the video is edited, I'll upload it to youtube...

Thanks

Many thanks.

Hi all:

I've upload to Youtube a video with all the process to install the Hackers Firmware. The video is in spanish (sorry, but my english is awful). Feel free to ask questions. I think the video is easy to follow, and I've included all the files that are needed in the description.

Thanks.

I think you forgot to include a link?

Sorry. I didn't know if it was ok to put the link in the forum.

Thanks for your advise.

Great!

Thanks for the video. Very good quality. (auto)English subtitles are quite fine too

When I have a moment I'll upload the thread to point to the video and probably will check those broken deb packages too.

Great video Tirwal, Unfortunately I didn't have enough time to edit and clean my markdown tutorial and post it. But your instructions are easy to follow.

If the reader is suspended does it drain the battery? Are there some options in KOReader to decrease or eliminate battery drain while suspended? I am not entirely sure but I think that my reader while at full charge got depleted even after I powered it off. Thanks.

Yes, but normally that should take at least a couple of weeks.

On Kindle and Kobo KOReader will power off the device automatically after a while, 3 days by default otoh. But at a glance that doesn't seem to be implemented on Cervantes.

grep for WakeupMgr and wakeup_mgr in the source. There's some chance it'll pretty much just work as is, unless those devices don't support the required functionality at all.

Edit: but in short, if you know you're not going to be using it for a week it might be better to power it off immediately if you don't want the battery to drain a little bit.

Hi, I ended up bricking my Cervantes 3 and no automatic restore is working. I have read that there is a manual resorarion procediure with the first step is:

1-Boot the device using a bootable system in your microSD (see how to do it below, at microSD boot instructions).

An on how to do it steps 2 says

2 - Copy a working root filesystem on that partition of the, you can copy the entire rootfs partition from the device internal memory (mmcblk0p1 for Fnac Touch/Cervantes Touch/Fnac Touch Plus/Cervantes Touch Light y mmcblk0p05 all the later models)

3 - Copy a kernel image with path /boot/uImage (base kernel is included in the base rootfs included in the link of previous step).


Has anyone have those files in order to try to unbrick my Cervantes?

Thanks!!

Hi there,

I wanted to share my experience getting koreader working on my BQ Cervantes Touch Light reader. According to the original post of this thread, it's not 100% supported and I have definitely found some problems to make it work. However, I have a pretty functional version of the software working and I thought it could be a good idea to share.

Step 1: Unlocking the device. The first step involves installing the developers firmware. The BQ Cervantes Touch Light has it's firmware in a hidden sd card, only accessible by disassembling the device. You'll need to pry open the plastic case, which is REALLY difficult to do without breaking it as the plastic is really brittle. Mine got broken in 3 parts, but I was able to put everything back together with the help of some glue (the kind used for mobile phone repairs). Once you get access to the mainboard behind the screen, there is a 4gb micro sd card. Simply remove it and connect it to your main computer using an SD reader. Partition 5 in this SD is the one that gets mounted in /mnt/private. You will have to mount it in your computer and create an empty file "hackers_ok" to enable the developers firmware to be flashed. Just create this empty file, and install the sd card back in the ereader. You can also copy the rest of the files needed for the installation while you have this sd card mounted on your main computer, but it's not strictly needed.

Some relevant information:
- The dev firmware is still available for download from the archive.org link here.
- For Cervantes Touch Light the latest version available is 5.2.0.
- The ko-deps archive contains a corrupted iproute package. There are links posted in this thread to alternatives, these should work fine.
- In order to flash the dev firmware you'll need to switch off the reader, and switch it on again while pressing the "home" button. Or at least, this is what worked for me.

Step 2: Install Koreader. Once the dev firmware is installed, simply go to settings and enable telnet access. You can connect via wifi using a standard telnet client. Follow this instructions in the first post of this thread to install all the necessary files under /mnt/private

Step 3: Fix Wifi. Once koreader is installed, the main issue I found was the inability to connect to Wifi. After some hours of debugging and reading about connman, wpa_supplicant, and wifi drivers in linux I found out that the Cervantes scripts in koreader try to load a wifi driver that is not correct for the touch light version. This can be observed in line 11 of /mnt/private/koreader/enable_wifi.sh. The script tries to load module "8189fs", but the correct module to load is "dhd". Another change is necessary when loading the wpa_supplicant command, "-D wext" needs to be changed to "-D nl80211". With these two changes wifi does work again. The disable_wifi.sh script needs to be changed as well to unload the right wifi driver.

Your enable_wifi.sh should look something like this:

#!/bin/sh

# Debian Wheezy ships an old wpa_supplicant binary (1.0.3). Please refer to
# https://manpages.debian.org/wheezy/wpasupplicant/wpa_supplicant.8.en.html
# to see which command line options are available.

# Do not run this script twice (ie: when no wireless is available or wireless
# association to ap failed.
./disable-wifi.sh

if ! lsmod | grep -q dhd; then
    modprobe dhd
    sleep 1
fi

ifconfig eth0 up
sleep 1

wpa_supplicant -i eth0 -C /var/run/wpa_supplicant -B -D nl80211 2>/dev/null

I hope at least someone will find this information useful. Koreader gives a new life to this old reader.

Best regards!
