last night I was reading online comics and it suddenly not respond so I force it restart and it was worse. My kindle cannot recognize my touching.

It is strange that TWRP still works. Restoring doesn't helps, too.

So I wipe it all(except for sdcard) and install various cm9 and cm7 with corresponding kernels from hashcode with no luck. Cm9 is ok but without wifi. Cm7 just wont respond.

Also I tried using TWRP to go back to pure stock and wifi still not working. So I redo all the root, twrp again.

Finally I fix permissions and install cm7 aka now it's screen recognize my touching but the wifi still cannot be turned on.

Is it possible wifi chip has been broken?

Any one can help me, THANKS!?

I was wondering what remains the same after I flash roms. Because installing zip has formatted boot, data and system.

I hard off the device when the wifi went wrong. And the application in which led to this situation cannot be reinstalled(install said OK but openning it the screen was black, still responding to button savior).

So maybe the problem lies in the internal storage that is unchangeable. Any one helps!? Or should I contact amazon CS?

Half of the old apk is probably left in data/app
Happened to me once.

But why the wifi still cannot be turned on? yes, it is when I using the app the wifi connection seems to be unstable, and I pressed the power button for 20 seconds.
Thanks for your reply.

would try to clean up the wifi configuration:
turn wifi off
look for /data/misc/wifi/wpa_supplicant.conf
open the file and delete everything except the first two lines, they are:
Quote:

ctrl_interface=tiwlan0
update_config=1

this is for stock rom - for cm7 it has to be simmilar
turn wifi on again

hope this helps ...

Thanks all the same.

I used root explorer to search for wap_supplicant.conf since it's not in that folder and delete everything except the first two lines. (forget to mention that my wifi just shows turning on and I can't do anything, flash new roms won't help.)

Then I reboot it the result remains same.......

did you try to restart your router ?
because i have this sometimes with the stock rom - wifi tries to connect and can't - all my other devices work fine - i use to reboot to router and the kf is connecting immediately again

I'm sure it has nothing to do with my router. because I live on campus and use school wifi. wifi is in the state of turning on since booting. regardless of flashing new roms.

thanks for your reply.

just closing out all known issues ...

but nearly running out of ideas at this point
maybe something on your sdcard partition ? - i know it sounds crazy but i had a case where the fresh installed rom did not start until he copied the whole sdcard partition to computer as a backup and deleted everything (besides .android_secure and twrp folder)
