Bricked device with no serial response

Hi,
I have just bricked my device.It stucks at the man-under-the-tree picture when boot up and can not be recognized by computer.When I connected it with serial , it has no response.What should I do now?

What I did before it bricks:
1.Mounted the filesystem to rw (and probably forgot to mount it back)
2.Updated the busybox(extracted from https://play.google.com/store/apps/d...ricson.busybox works normally before it bricks)
3.Installed pip using get-pip.py and installed ftpdlib
4.Changed iptables rules(-A INPUT -i wlan0 -j ACCEPT)
5.Transferred some book to it with ftpdlib
6.Put a screenshot in the linkss folder,and enabled screensavers hack
7.Reboot and BOOM

Which step will probably brick the device?I would appreciate it if you can give me some advice.

I'm going to go out on a limb here and say busybox .

You should *never* replace random binaries in a system that's essentially a black box, even if said binaries might appear to come from "standard"/OSS tools.

(Plus, Android is NOT Linux. You can't assume Android binaries will run on Linux, and vice-versa).

The entire system is highly dependent on the version/build of the Busybox it ships with (which, since this is linux, expects the Linux C library to be present).


Replacing that with a version/build of Busybox built to run on the Android C library (Bionic) -- WITHOUT also supplying the expected library ==



three things have saved you:
*) Your Kindle is dual boot and you have not (yet) trashed the alternate (Diags) system.
*) The update images that Amazon posts are complete (Main) system images.
(And our KindleTool will let you unpack that to get at the files you need for a fix).
*) All of the "HowTo" information is already posted, multiple times, enjoy yourself learning the differences between Amazon/Linux and Google/Linux (a.k.a: Android) embedded systems.

PS: First thing to do is fix your serial port interface.
There are only two ways to prevent it from having an output
*) Complete meltdown of the SoC
*) User error in making the connections (current evidence points at this cause).

That might be the problem. I have poor soldering skill,so I just use tape to connect the wires. It worked well before,but I have no luck this time.Or maybe my converter is broken.I will get a new one and try again next time. Thanks for your advice.
