G1 Black screen, Cannot get to bootloader

Hey, I have been given a phone off a friend to fix but it wont turn on. Booting normally, I get a vibration and then the backlight comes on but i cannot see anything. When i try to boot into the bootloader by holding the camera button and powering it on, the backlight comes on but nothing else. I cannot see the bootloader. Under both circumstances, I cannot turn the phone off. I have to pull the battery to turn it off.
Does anyone have any suggestions about a possible fix? Thanks

Havie you tried send when trying to enter bootloader? If it resets then you can still get to bootloader. If not, your friend has soft bricked and only way is to JTAG which takes strong hardware knowledge and steady hands.

ok im having the exact same problem. actually i thought it was a battery problem so i spent 77$ on a 3700 mAh new batter i guess tripple life... and got it yesterday booted gave same problems. black screen where T-Mobile should be yet the rom loads with scribble screen meaning u see part but it looks like the pixels are messed up. so actually decided to resort to what someone told me a Factory Reset so Pressing Camera + Power i got a Black Backlight screen yet wont show... and I cant turn it off without Taking out the Battery this has become a issue after installing cyanogen 5.0.7 T5... since then i Re-rom'd to superbad 1.2.5 same problem screen scribbles and stops im thinking did I fry it i dont even know how to google my problem because its pretty unique it isnt a battery issue its something in the hardware ... or am I wrong please send us some feedback... ill keep this thread in mind

Sorry, what do you mean by 'send'. I am a complete noob when it comes to G1's. I have worked out i can shut off the phone by holding call + menu + end but thats it. I still cannot see anything at all on the screen. I still only get a vibration on boot. How would I know if the boot has been sucessful but i simply cannot see?
Could the flex ribbon cable be nackered?

[Q] my sgs screen blank but touch screen still working<<any1 can help???

my sgs last time i mod with CM 6.1.its still ok.but 2-3 days again my sgs suddenly got a blank screen>>>3 button not working until i use my cable charge to PC its cant on but just only sound go to sgs home screen.>>no pic i cant say but my touch screen still working>>plz somebody explain my sgs ??i'm from Asia.plz give me solution brozzzzzzz.thks alot

Sometimes my SGS blacksout also, but i know it still works cause i have haptic feedback on.
for me it's very easy to restore the picture
it always works with one of the following two options
A) Push the home button
B) even thought the screen is balck, go to wallpapers
one of those will always bring back my screen for me. Again this only works if the phone is one and responsive, just the screen that goes black.
Let me know if it works for you
Thanks you,

Problem with Droid 1

I’m using CyanogenMod 7.0.3-Droid. After using the phone for a while the icons on the screen start moving back and forth very rapidly and start randomly launching apps. The phone becomes unstable and I have to press the on/off button to get the phone working normally again but it only lasts a short time and starts over again. Any ideas?

Sounds like a broken digitizer (touch screen)
Try flashing back to stock - but I doubt it's a software ploblem
One question though: was the phone connected to an AC charger when this occured?

I think it is a broken digitizer. I flashed back to the stock rom and two others and it still does the same thing. I didn't matter if it was charging (OEM charger) or not, it stillwas acting up. Thanks for the reply.

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

[Q] after the first update my phone wont start

After my first update the phone is dead, I have my htc inc s for one
week(I think it was android 2.3.3 and it worked fine yesterday I got
update notification I've downloaded it and then the phone shutted down
and started with the dark screen with the green arrows in circle and
one inside facing down symbol and it stayed like that forever!I took
battery out and put back press power and its the same symbol! The phone
is from china got it from ebay and if I need to send it back for fixing
it will take a lot of time to come back!
So I tried battery out back in, volume down + pover the same green
arrow symbol,like this when plugged in my pc doesnt do nothing,after I
tried battery out than in, volume up + power and I got 3 vibes, orange
light and black screen, when plugged to my pc i says "qualcom CDMA
technologies MSM" device and it searches for drivers!
I dont believe that its possible to brick my device with the first
update that I got from the mobile network and I never touched nothing
like rooting or messing with my phone...
So what can I do now to fix it without losing my waranty and having
everything like it was before stock and working???
PLEASE HELP PLEASE HELP!!!
