EBS, can you use the serial console to peek into recover mode update install scripts? A while back hand-made updates would fail to install and no one could figure out why. With international Kindle updates fail in similar fashion even when not in the recovery mode.

It looks like Amazon has some additional check that was done only for recovery mode and in software 2.2 it is done for any kind of update.

Figuring out what it is would enable screensaver, savory, unicode font and all other sorts of hacks to work on the K2i.

Dear mans,

I have the same situation as dr_g100k, but I broke it by installing unicode font hack and delete all the font folder in the device, and it restart and can not reboot. I still can access to recovery mode but I do not know how to restore it. Can any one help me? Thank you very much.

By "usb to ttl convert" do you mean you are attaching a USB-to-RS232 adapter to the Kindle and connecting it to the PC? Or do you simply mean that you tied onto the kindle serial port leads and ran it through a max232 to your computer (like EBS posted)?

thanks.

It is NOT the SAME.
You can fix it from serial console
1. Stop boot
2.
Code:
uboot> setenv bootargs $(bootargs_base) root=/dev/mmcblk0p1 rw init=/bin/sh
uboot> bootm 0xa0060000
When You will be able to recover your files

AFAIK I've understanded EBS, you need a TTL (5V) RS232 Port attached to Kindle side. You cannot attach a true RS232 port (+12VDC, -12VDC) because you can break Kindle internals. And if you've done it, it is practically sure you've broken internal Kindle serial port and the only available step is to soldering into Kindle if MAX232 (or equivalent) is available, but due Kindle board if you do not have an very good soldering station and are a skilled solder man you will definetively break your Kindle.

At the other side you need a RS232 port. If your computer only have USB, then you need an USB-to-RS232 with TTL levels or a USB-to-RS232 and then attach a RS232 (TRUE)-to-TTL RS232, that can be done with a MAX232 or variant.

I do not know if exists USB-to-RS232TTL converters, at work we use some internal boards made by our electronic engineer using FTDI chips and we can select configuration via jumpers and soldering jumpers...

Thank you very much dr-g100k. You are my saviour. I will buy a serial console RS232 to TTL 5v with 4 cabs as rfog said and try to connect with the device.
