e-ink/reader framebuffer device (killed it, sorta) - Page 2

pechter · 10-10-2011, 11:57 AM

I've got the same problem on my pocket edge. The e-ink side doesn't work anymore although it does correctly reset at the selftest. I'm going to continue to try to find out more about the badserial. It claims it wasn't registered.

SAME AS MINE. HOW DID YOU GET THERE?

tarvoke · 10-10-2011, 05:08 PM

vicinc I still feel like a golden upgrade with more checks removed would work for you - I forget, did you already try ktwombley's? http://bellybuttonporn.com/android/e...p-hellbent.zip

sorry if not, but at least it seems toyz and nikkie are getting closer...

vicinc · 10-10-2011, 07:04 PM

no did not work.

nikkie · 10-10-2011, 07:14 PM

Busybox is part of the default installation. You most likely overwrote the original copy with a version that won't work on the edge. We're working on getting the ability to copy over a fresh file system - in the mean time, I'd get your cabling system worked out so that you're ready when we have something.

vicinc · 10-11-2011, 10:42 AM

do you think that we must get a cable and open the device to proper firmware once you crack it, or we can simulate OTA procedure or android adb?

nikkie · 10-11-2011, 02:39 PM

AFAIK and have seen, you can't use adb over serial, or get it to start running via uboot. You have to have a working OS. And to have a working OS, you have to have a correct filesystem. So you'll to correct your image by instructing the device to fix the FS with an update.zip before you can do anything with ADB.

i do have an android only device, with adb working?!? but no eink

pechter · 10-11-2011, 06:38 PM

The problem is caused when putting in Busybox and OpenVPN.
More research is needed on my part to figure out what goes wrong.

I fixed it!

I found an original copy of /system/esi/bin/busybox in the ermine EE update.zip by unziping it and then unzipping system1.zip.

Then i did a "adb push system/esi/bin/busybox /intsdcard"

I shelled into my rooted EE with "adb shell".
Then at the $ shell prompt:

# go root
exec su -

# get a better shell( instead of sh use ash)
exec busybox ash

# remount /system read/write
busybox mount -o remount,rw /system

# copy the file to /system/esi/bin
cp -a /intsdcard/busybox /system/esi/bin/busybox

# clean up
rm /intsdcard/busybox

# correct the gid
chgrp 2000 /system/esi/bin/busybox

# correct the permissions
chmod go-w /system/esi/bin/busybox

# make sure it looks right( like nearly all of the files in /system/esi/bin)
ls -l /system/esi/bin

# done! remount /system read-only
busybox mount -o remount,rw /system

# reboot!
reboot

I recommend backing up /system/esi/bin/busybox before upgrading to a newer busybox version.

BTW, I use the adbwireless app and it works great! The only drawbacks are that I have to toggle it after a reboot and it's insecure to others on your wireless lan with the android adk installed( not really much of a worry at home).

adb connect 192.168.1.100

It's not neccessary to use 192.168.1.100:5555 because 5555 is the default port.

Welcome, ryoohki! What a great first post!

ryoohki · 01-08-2012, 04:58 AM

There's a command to update the checksum database, so I assume the correct answer would be to update to the latest and feature-full busybox and then fix the checksum issue correctly.

I'd like to hear from anyone who also fixes this issue with this method - by down grading to the original version of busybox in /system/esi/bin.
