blank screen after turn phone off and on.

[Guest plegdroid]

Afternoon, well I got my new LCD, the problem I've now got, is the screen works ok from boot, but when the screen turns off, or I turn it off, when I return the phone back on, the screen stays blank which is not good :( .

Does anyone have any ideas?

F.I.A :)

Different screen driver maybe? I'm sure I previously read something about that. You may need a kernel that fully supports it.

thanks, I'll have a scout around, I've tried ceco's staraddict kernel, it's boots ok and the screen works until it turns off, then black screen. :)

Try normal S Series kernel. Not the sfr one. Might do the trick.

So you replaced the screen yourself or service did it?

Didn't they flash appropriate stock rom?

[Guest C3C0]

You could also post output of "adb shell cat /proc/kmsg" done while booting.

afternoon, yam tried all kernel and prox fixs, I fitted it myself, it could be the LCD itself,it flickers at high brightness and when on charge with the phone off with the big green battery,the whole screen goes on and off . I'll try and grab adb shell. :)

[Guest C3C0]

Regarding phone-off-charging animation.

I already had such a case with one Skater from Uzbekistan.

I found out that the bootloader that is stored in appsboot.mbn of TPTs we normally use for repartitioning was snot compatible with his model.

See here.

evening, ive tried to grab cat/proc/kmsg, but get

C:\zteadb>adb shell

shell@android:/ $ cat/proc/kmsg

cat/proc/kmsg

/system/bin/sh: cat/proc/kmsg: not found

127|shell@android:/ $

also, how can i start log with the phone off, as it dosnt recognize the device until turned on? :)

[Guest C3C0]

You're missing space after cat

Log is not possible while phone's off.

I can't see any problem here.

kmsg is more important to see since there we can see the initialization of screen hardware.

Essentialinfo is missing,though.

You need to cat kmsg immediatelywhen it starts booting.

You should see info on cpu freq table being initialized.

lol,i retried. re adb,is there a quick command that can be used?

than having to request adb shell untill the device is found,request adb shell,let it grant shell,type su,wait for that to be granted,then type the proc/kmsg request. or must i just need to type quicker?

:D

[Guest C3C0]

Try this single-line command

adb shell cat /proc/kmsg

su is not needed to read kmsg. Well depends on rom.

but in that case just do

adb shell su; cat /proc/kmsg

[Guest plegdroid]

please advise if I need to grab earlier still than this ?

with much thanks :)

[Guest C3C0]

Still not enough...

Prepare the command, turn on the phone and execute it. If it gives error about device not present execute immediately again until it catches (keyboard up key will get you last command so you don't need to type it again).

[Guest C3C0]

And be sure your command prompt has enough scroll buffer set so it doesn't trim the very first lines when output exceeds the buffer

. Or you can redirect output to a file
