hahaha no but seriously.... if it totally cant switch on... theres probably no way that they can trace that youve rooted your device so youll probably still be covered under warranty (hopefully)

[Q] Galaxy S DEAD! Jumbled white screen

hi guys
im using darkky's steel ROM on my galaxy since the last few days.. it was working perfectly..
last night i put in in for charging like i always do and when i see it in the morning the screen is continuously on with some strange white jumbled up screen which i havent seen before.
the phone doesnt switch off nor does it go into recovery mode nor does it go into download mode (it used to before be able to go into recovery or download mode).i need to pull out the battery for the phone to switch off.
each time i try the 3 button combo .. it comes back to that jumbled up white screen.
i havent tried connecting it to ODIN since i cant use 3 button anymore.
does it seem to be a hardware issue ?
please advise guys
thanks
IF you are unable to use 3 button, you could try to install adb (from the Android SDK) and connect the phone and try the following commands:
1) adb reboot recovery -> to go to recovery OR
2) adb reboot bootloader -> to go to download mode
Good luck!
Odin uses download mode to flash, but sounds like you have killed something in the bootloader, you have 2 options:
1)send it to Samsung and hope the don't kick you in the nut sack for breaking warranty, ending up in no fix or...
2)turn the phone off and insert the micro usb modded cable with a resistor over pin 4_===_5 301k resistor as described here http://forum.xda-developers.com/showthread.php?t=819551
I flashed that rom and got the the very first screen when the phone turns on, 3 button went but download mode didn't, i flashed I9000XWJM8 and it came back to life, tried it again making sure lagfix was off and it done the same, needless to say I am back on docs jp6!!
good luck pal
@ashwinds: he cant run the commands unless the phone boots as both download mode and 3 button are disabled

Can you post a pic of the screen?
Also, when you remove the battery, then put it in, and try to go into revovert/boot, or try to start the phone, do you see ANYTHING else before the white screen?
hi
@kalpik will try to post a pic when i get home tonight.. nope dont get ANYTHING at all before the jumbled white screen.. just that.i just hope the guys at samsung dont reject my claim because of warranty violation issues.
@anarchyuk i wish i could try the method u u suggested.. but i really dont know anything about hardware stuff and am sure that i wont be able to do it.

If the white screen is the only thing you get, then i think its a hardware problem only.. Though Sasmung should fix it for you.. If they ask you about anything, just act dumb

see what samsung say, but if they do fail that method is not hard at all, as usb leads are only 4 pin and micro have 5, not all the micro pins have wires, other wise it would be a case of putting the resistor into the usb Male end!
Try this, it jas helped me get into recovery before when all appeared bricked (but didn't have a screen like yours).
- Remove battery
- Now press and hold the buttons you use to get into recovery
- While still holding the 3 buttons, insert the battery
Hopefully it boots up and/or ADB works.

HELP HELP

plz help....was using Zeus v6.39n overclocked to 1100Ghz and underclocked to 200Mhz..downloaded some Lg stuff from Heuxx's blog(car home & smartshare)...rebooted my phone to flash it and it won't boot after that....tried everything, no use...then finally use smartflash and flashed to v20B....phone booted and I was installing my apps...after some time the display went off as it got locked while I was not using and now its not coming on....Iam getting calls and messages and the LED lights are blinking but the screen is blank...tried reflashing....now its not booting at all....NO LG logo also...although I can see the LED blinking...plz help
try flashing with smartflashtool again
i think it might be your lcd itself or the cable
i have alredy flashed 2-3 times....also after I remove the battery and put it back and switch it on, I can hear the sound of LG animation like when it comes in stock and the led lights are blinking normally as it happens during powering up...But the screen remains dark...
sumthing happened to ur screen then... if u still have ur warranty then bring it to them.
if it's because of the screen then they will replace it for ya
thanx....I went to the customer care...they also tried flashing(I guess)...then they told me that its not due to software but hardware problem and that they will replace and give next week

Emergency Mode

Hello!
What I must to do if I want turn on emergency mode (with yellow background) on this phone? Thanks for help!
I havn't seen any modes with the yellow background on my phone when I had the stock firmware, the only ones I've seen are the ones dexter found
http://forum.xda-developers.com/showthread.php?t=1741892
I believe the lg pc suite can help restore the phone or was it lg mobile support tool, but it will probably download the firmware from lg and I don't know if you'll be able to root or bootloader unlock this phone with a newer firmware than v20a
you can also restore the firmware if you have the KDZ file using this tutorial

Could you tell us what caused the problem? That might help to pin it down.
In the mean time see if you can enter S/W Upgrade mode. Hold the volume down button and plug in a USB cable.

Excuse me for pointing it out, but you are being too concise in your descriptions.
Is the phone even working?
Since you have no buttons, no screen, no PC connection, in lack of more details I tend to believe that it could be turned off and unable to be switched on.
Have you ever had problems with power button?
Have you checked your battery?
It could have been fully discharged, have you tried recharging it for some time?
Does the phone reacts when plugged to a recharger?
See? in a single post I put mor questions than all your statements you put in three of your posts.
You are not helping people to help you.

[Q] Issue with screen not turning on till rebooted (Custom ROMs)

An issue I've had with a few roms I've used in the recent past. Currently on Mourta's Liquid Smooth rom (KK). Sorry if this question has been asked before, I wasn't able to find any info.
Sometimes after turning the screen off, if I try to turn in back on, it won't. Trying to unlock the screen makes the hardware button's backlight light up, for a few seconds like normal, but the screen never turns on till I hard reboot the phone. The rest of the phone doesn't seem to freeze up. For example, music doesn't chop up, I still receive calls, and holding the power button gives me the vibrate signal that the power menu has opened.
I've re flashed the rom a couple of times, but I still get this problem on some level. Even if I leave the phone undisturbed for a long time and come back to it, the screen won't turn on till I reboot. Not sure if this is true, but I think the problem also happens if I try to unlock the phone too quick after locking it. Thoughts?
Already know problem on some roms it is called Screen of death sometimes happends because of low screen cpu freq sometimes because rom just go nuts.

I wanted to know if this particular problem had a name. Screen of death sounds apt. I wouldn't mind having to reboot a couple of times, but this problem has me rebooting well as much as 6 times a day
Lets call it Greg then. Flesh another rom and try it. Cm for example.

i think u need to do a factory reset
sound like a firmware problem
what firmware are u on
Mine does some blinks when i'm getting in or out of the always on screen display mode, but not everytime. got it in more than 1 rom.
I don't have such issues on my SE.
[/COLOR]Dang it. I'm experiencing the same issue for the past few days with my Global ver. Mi8.
Any solutions?

Installed "dark mod" miui theme today and this resulted in a white strobe light screen after the first unlock attempt... No way to stop it's or access anything.
Slight panic since I'd seen threads about this issue and assumed it's hardware problem
Only way to stop it was a forced power off by long press of the power button.
Luckily on next boot the screen was working and I was able to Uninstall the theme again
Just when I was about to go to the service centre today, my phone becomes normal. Not sure why though.
How about you guys phone?
