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?
Hi Guys, I put my G1 in the drawer after I got my SGS, and just took it out to wipe and give to my Mother. Battery fully charged btw, and i was running CM6 before (working perfectly)
now the device powers on, i can see the screen backlight is no but nothing happens, cant get into fastboot, cant get into recovery, no logos, but the thing is definitely powered(vibrates once).
any ideas?

i got the same with my dream.... still dont know whats wrong
maybe your screen is bad?
Greetings all!
I have an AT&T Tab that I got a few weeks ago, and yesterday I let my curiosity get the best of me and decided to flash the Euro firmware to enable the calling function. It flashed flawlessly and, popping my personal SIM in, I could easily make calls and text and was pretty happy with the experience aside from two things. First, the home screen was no longer centered (page 3 of 5) but was on the far left on page 1. Petty concern, perhaps, but I really prefer the symmetry of the stock AT&T layout (as well as HTC Sense). I haven't enjoyed any aftermarket launchers so I didn't want to bother when them, and that would have been acceptable enough if it didn't result in the loss of my Media Hub and the $50 credit I got from registering the device with Samsung. Also perhaps a petty concern, but a concern nonetheless.
After getting it fully rooted and adding apps, the Tab would freeze horribly, becoming completely unresponsive and requiring a hard reset. This was after installing Titanium. But by this time, I decided to have a go at reflashing the stock ROM as provided by rotohammer. He did indeed warn us that there was no boot screen, and he was correct. Aside from that the experience is completely stock and just as it should be.
But the reason for this thread is...WTF can I do to get some sort of flash screen and boot animation so I'm not looking at a black screen for ages until the lock screen comes up? I've tried replacing the boot animation ZIP file with some files provided on these forums using Root Explorer, and it has no effect at all.
For some of you brains out there, I'll present a bit more info that may be of some use if you're willing to try to figure out a resolution to this:
Upon powering it on, the Galaxy Tab Samsung image appears for a second or less, then the screen goes black. After a few moments you hear the chime that accompanies the normal Samsung boot animation, but the screen is still black. Finally, after the typical length of time for booting, you can access the lock screen, but you have to hit the power button to get it to appear; it doesn't just light itself up as it should. I actually have to put it to sleep with one push, wake it up with another, then the lock screen appears and I'm using my Tab like normal. There was one time that I pressed the power key as it was booting and I saw the image of the boot animation briefly, but that's not typical.
Another thing that might help you figure out the root problem here is that I can't boot in Recovery. I power off completely, hold down the Power and Volume Up keys until I see the backlight come on, but the screen remains black. I can't actually see any of the text on the screen, but I know from experience that the device is in Recovery because if I hit Power, it reboots again, just as it would if pressed in Recovery (when the reboot option is highlighted).
When I put it in Download mode, I do see the normal screen with the Android shoveling.
Surely the inability to see splash screens and boot animations is related to not being able to see the Recovery menu, right? Can anybody help me get a splash and animation going on this without affecting anything else? I know that this too may sound petty to some, but I really want to make this the perfect tablet experience, like it was before I started messing with things.
I should also note that the shutdown animation works just fine. So far the entire experience seems pretty normal once you get past the boot.
Several peeps have had a blank boot screen issue after flashing a rom on att tabs; myself included. The blank boot screen usually has a thin white line, too.

Thanks for the link! I looked around but didn't find any proposed fixes. Obviously overlooked this one.
However, that fix seems to be for people who go from stock to custom. In my case I went from stock to Euro and back to stock, but the resulting symptom is the same as described in the above link - except I have no white line, it's just black.
Given that I went back to stock and have this problem, will the above referenced fix work for me, or am I FUBAR? I don't want to risk bricking it just to fix the boot animation issue.
I cannot say for certain if it will help in your case. But here is my sequence of events that cause blank screen and when I applied the fix in the link:
Stock (non-blank boot)
Jmev4 rom (blank boot screen started)
Jmiv2 (never bothered to fix boot screen)
Overcome 1.3.0 failed install due to blank boot screen and cant 'see' recovery mode
Jmiv2 again fine but with blank boot screen
Follow link to fix blank boot
Jmiv2 now with fixed boot screen
Overcome 1.3.0 success!
So maybe you can apply fix to stock?

Hopefully some of our dev wizards can chime in? I'm wary of trying something out that might turn my Tab into an expensive scrying mirror.
I ran the fix for the blank boot screen. Odin declared the flash a success but I can confirm that it didn't fix a goddamn thing! There is absolutely no change in the device whatsoever after installing the jj4 bootloaders.
Just to confirm, it was downloaded as a .ZIP file which contained a .TAR file. It was the .TAR file that I added into the PDA field; that was correct, right? Or was I to insert the .ZIP in the PDA field?
Does anybody have any idea why there's no visible splash screen, boot animation or recovery mode screen? Rotohammer: are you still alive? I got this stock ROM from your post; surely you've figured something out by now, no?
If Samsung/AT&T finally release 2.3, do you think installing it will resolve this issue? Where is everybody that could help with this??? Have they all forgottten about the Tab and gone on to bigger screens/greener pastures?
Why does every Gingerbread ROM I use on my OG Droid boot up with the boot animation and then the screen turns off after a few seconds like it times out? It will not do anything until you hit the power button. After you do that, and only after you do that will the boot animation resume. Then finally my lockscreen will appear shortly after that. It's sometimes annoying to deal with on every single boot.
Any thoughts on how to resolve the issue? Is it because the OG Droid will never see an official GB build... or something else? Maybe it's a simple solution?
Was on Facebook and my droid screen went black it still has power but I can't do anything I shut it off and turned it on and it lights up with all different colors like when u lose signal in an old tv and it's salt and pepper I can get into the boot menu but recovery won't work ap fast boot failed to fix and if I let it go I get the dual core logo and it's stuck there is my digitizer screen broke cause I'm confused why will it load the boot menu and the logo but not everything else?
