Hi,
This is about my Samsung Vibrant. I flashed a new rom onto it and after the regular installation the screen turned black and would not turn back on. Like nothing works. No lights, no anything, like the power button hasn't even been touched.
Is my phone bricked? Is there any fix to this?
Thanks
what do you mean black screen? as in no power at all? Even when charging the phone?
Yeah. Like it looks like the phone is off. Just black
have you tried removing the battery then going to DL mode?
I've tried all three button combinations.
Removing the battery and then holding the two volume buttons and inserting the battery then pluging it into my computer.
Nothing seems to work. The phone is unresponsive and the screen remains black the whole time. The four lights on the bottom of the screen don't even light up.
Hmm, let's wait for the others but i think....
Guide in signature should help
2. Remove everything from your phone (SD card, sim, battery).
3. Plug your phone into your computer WITHOUT the battery, as you have already taken it out in the last step.
4. Press and HOLD vol. up and vol. down.
5. As you are HOLDING these buttons, reattach your battery.
6. You should be in Download Mode.
This is under the NO-BOOT phones.
I tried and it doesn't put it into download mode. If I can get it back to download mode it would be golden.
I think they've rigged things to force download mode haven't they?i don't know if it will help but it might be worth a shot
Still flashing , thanks to odin
Check my guide under the troubleshooting section, it should have a link to the "Soldering Method" and THAT will force it into DL mode.
But I'd advise you to CAREFULLY follow my steps again before spending time and money on the soldering methdo x) Just a thought

First of all, I'm not sure if my Vibrant is "hardware-locked" or not - the battery has a date of 8/25/10 printed on it, the sticker behind the battery says "10.09." Either way, I cannot get into download mode. The phone was purchased 1 week ago today. I was simply attempting to disable the voodoo lag fix (using bionix 1.3 rom). I have tried every combination of getting the phone into download mode that I can find - is it possible? I sometimes think it's close to working because during the process a window on my computer pops up that says "hardware not installed correctly" which to me means that I was close. Someone please tell me if it's even possible to get my phone into download mode - it will start up, do the samsung galaxy animation, then go to black screen with the bottom buttons lit up. Thank you for any help you can provide - it makes me ill that I spent $500 on this 1 week ago and am now faced with a complete brick.

yes, when i rooted it, i used 1-click
Try this:
Take battery out
Put battery back in
DO NOT TURN ON PHONE!
Plug in USB
Wait for the green battery screen
Hold vol+ and vol- at the same time
Hold power
When the battery screen goes black, let go power ONLY.
I had a HW locked phone and this method allowed me to get into DL mode--still couldn't get into recovery, but at least I could use ODIN. Was a null point as the phone is bricked and a new one is on its way...
When you say a new one is on its way, did T-Mobile exchange it under warranty even though it was rooted?

If the above doesn't work.
Plug in USB to PC only
Insure Phone is off
Hold in Vol + and -
Plug in USB to Phone Holding Vol + and -
Release Vol + and -
Walla you are in Download Mode
Neither of these methods worked. what are the chances of t-mobile performing an exchange for me if all else fails?
you could try this too, it worked for me.
remove battery and put it back in.
plug in usb
hold vol up, vol down and power button.
when you see the vibrant home screen, keep holding the three buttons until the screen turns dark.
let go the power button and vol up but keep vol down pressed, you should be in download mode.
hope this help.

Since we all seem to have our own variations of this method, I can tell you the one that worked for me 99.99% of the time on the first try when I was stuck at the Phone ! Computer screen.
1) Remove battery
2) Hold Vol - and Power
3) Insert battery while holding these buttons
4) Plug in USB if it works.
Some have reported T-Mo swapping the device due to the inability to access download/recovery mode, but it doesn't seem to be something they will regularly do. Others have been successful by using the inaccurate GPS issue to get a replacement. Specifically by insisting it is not just inaccurate, but downright non-functional.

Yea...I tried relashing the stock rom using ODIN--for 4 hours over and over. It said "successful" in ODIN, but the phone was toast (would go past S boot screen then nothing. Just walked into TMO, said it "just would not do anything" with a feigned puzzled look and after a amateur cursory inspection the rep. just did his thing on the computer and a new phone is being sent to my house via UPS.
Hello, I was trying to flash my phone using ODIN and Eugene's 2.2 ROM. Things were going well, until I accidentally nudged my computer, which apparently has a very loose USB port. ODIN tells me that the phone disconnected. Plugging and unplugging the phone again would not work, so I was forced to do a battery pull. I am now stuck at the Phone /!\ PC screen, and the Volume Up, Down, Power button sequences do not work. Am I totally screwed?
Thanks.

No, youre not screwed. Remember that the Vibrant is nearly impossible to kill. Reboot and hold both volume buttons + power at the same time and when you see "Vibrant" on your screen turn to black then let go of power and Download mode will pop up. Then do Odin.
My phone went to that screen as well. Didn't get there the same way but here's what got me to download mode...
Pull battery, sim card, and sd card. Put battery back in but do not turn on. Plug usb cable into computer and phone. Start Odin. Hopefully your phone shows the charging image, now hold both volume buttons and power button until the vibrant screen comes up. Immediately release the power button, keep holding other two buttons. It should boot into download mode.
Flash with Odin like normal and then replace sim card and sd card. I had to do this twice yesterday.

Unfortunately when I plug in the USB cable after putting the battery in, it does not show the charging screen, but the Phone /!\ PC screen. Additionally, starting up the phone while holding the Volume Up, Down and Power buttons also brings me to the same screen. It seems like my phone is the kind that does not have the 3 button download mode option. Is there any other way to get out of this screen?
Well, I've never had that situation but I'm pretty sure it's fixable. The Vibrant is almost impossible to brick.
You'll gave to keep searching and wait for someone more knowledgeable than me...

Well the help is much appreciated anyways! I hope I don't have to hack a microUSB cable with soldered resistors and such. Does anyone have any ideas?

i just fixed my phone when it was like that, just plug the usb cable in, hold both vol buttons and the power button, it may take a minute or so, but you will see your screen go completely black, let go of the power button and keep holding the vol buttons, and you will get in download mode, trust me, i panicked just like you, just keep trying it, it took me about 30 minutes to get in download mode
Thanks for the advice! Should the battery be in while I'm doing this? If so, should I put the battery in before the usb cable?

yes put the battery in, and then plug in the usb cable
Heres whats happening right now: when I plug in the USB cable, hold down the Volume Up, Down, and Power buttons, a few seconds later the screen will go black, at which point I unpress the power button. But this does not bring me to the download mode, it just brings me back to the error screen. If I press all 3 buttons again, as before eventually the screen will turn to black, but it will always bring back the error screen. It also behaves the same whether the USB cable is plugged in or not. I suppose this is progress, but am I doing something wrong? Arent I just supposed to let go of the power button when its black?
I am having the same problem except I am only getting the Vibrant screen. I have been trying to fix this for hours, and am about ready to go swap the damn phone out. It is literally driving me crazy. NONE of the methods to get to download mode are working.
[A] I'm screwed, arent I. (Brick, Phone ! PC, no download mode)
From what I hear, 1 in 3 Vibrants won't go into download mode in this situation. Mine does it just fine, my buddy's phone - no dice. I bricked it, so I fixed it. The solution was the spare micro usb + solder + 301k resistor(s). It worked perfectly, the 1st time. I'm a skeptic turned believer! It cost about $8.00 for the cable & resistors at Fry's Electronics.
Sigh, I guess I'm going to have to build this thing then, which is great because the nearest radio shack is 5 miles from my place. Ah well, better than having no phone.
I commend you in your efforts! Once you get out of this you'll be truly unbrickable. GL!
I was discouraged by the fact that I was far from a Radio Shack, but I looked online and it turns out you can actually create a resistor by drawing a line in pencil on a piece of paper. I have a multitester and stripped phone wire, and was able to duct tape the wire on specific points to get 302Kohms! Unfortunately thats where the project stopped, because I don't have a spare microUSB cable to butcher haha. And a friend offered to drive me to radio shack so I don't have to be the poorest electrician ever.
I might still try that method though! Just for kicks.
Try this
Ok, so I see some ppl offered advice on how to get into download mode. That is great, but I found their methods to be very different from mine. So give this a go and see if it works before you go into MacGyver mode.
Please note: DO NOT PRESS THE POWER BUTTON EVER DURING THESE INSTRUCTIONS.
1. Take back cover off phone
2. Remove the battery
3. Plug the USB into your computer, and then the other end into your phone.
4. Hold down both volume buttons (do not press the power button!) and while holding them both down put your battery back in.
5. Hold in place for approximately 2 seconds.
You should now be in download mode. Keep in mind, you said that your usb on your computer is "loose." Be extra careful not to bump it or anything b/c if the phone isn't being recognized as plugged into a computer download mode will not work. Hope this helps!
I got back to stock via odin. I tried to re root and it will not let me. When I do adb reboot recovery I click on reinstall packages and it takes me to cwm recovery. I then click instal from sd card and click on update.zip says it installed but didn't after reboot.

Hi, I had that problem before, here is what I did to fix my vibrant. take sim, microSD, and battery out of the phone. Connect the microusb and turn on odin. hold down volume+, volume-, and power down. while holding them down put in the battery and it should get to download mode once boot. also odin should detect it.
Hope that work.
I have returned! Unfortunately none of the many volume up/down button techniques were able to get me into download mode, as I must have a hardware locked phone. Fortunately though, I was able to get a ride to Radio Shack, where I spent 27 dollars on a microUSB adapter, a pack of resistors and solder. The adapter and solder I didnt even use. I twisted together 3 100kohm resistors and 1 10kohm resistor (my multitester read 305kohm total, I guess thats the 5% tolerance). I never ended up using the microUSB adapter because when I cracked it open, I couldnt find pins 4 and 5, so I cracked open the samsung USB cable that came with the phone. Plugged it in, tapped the two ends of the resistors awkwardly to what I beleived to be 4 and 5, and it worked! First thing I did was get Eugene on there, put the casing back on the USB cable (which still works!) and then marked that USB port to never be used again. The phone works great now! Thanks to however discovered that 301Kohm trick, you are a life saver.
Thanks all!
Volume Down + Home + Power.
Works for me everytime Best of luck man
My phone is a Telus t959D
I am stuck at the phone--!--PC screen. 3 button combo does not work, please do not give me other 3 button combos because it will not work. I think i need to fix this battery problem first and the download mode will come itself.
Plugging it in to the usb gives me a screen with an empty grey battery, with the progress circle in the middle frozen.
I cannot go into download mode because when i connect the usb, the grey battery pops up.
If i turn the phone on with no usb, i get the phone--!--pc screen.
Making another thread on the wrong section with the same question should discourage people to help you.
Furthermore, people already gave you answers in the previous thread

So to clarify, you pulled the battery, then with one end of your USB cable plugged into the computer, held down your volume down button, then plugged in the other end of your USB cable to your phone (you should still be holding the volume down button) and after a few seconds you're still not getting into download mode?

Have you tried the above? Odin messed up a flash for me once and got soft bricked like yours, but I was able to get back to Odin via the above method. If volume down doesn't work, try volume up.
Otherwise, if neither works, just accept your phones fate and either get a USB jig off ebay or send your phone back in. Next time, stick to stock
This is the fix. Or should I say "Completely Stupid Time Consuming Trick" that somehow fixes the problem(at least for me) because now my phone powers off and on normally. Here the Steps I've done. I tested this out 4 times and it worked all four times but it was only tested on my device. So this is not guaranteed to work and its time consuming.
Step 1: Plug in charger and let it sit there at the black screen for 7-10min
Step 2: Plug out charger and hold down power button until phone fully powers off
Step 3: Hold Volume up and down at the same time and plug in charger. It should be in download mode. Let it sit there for 7-10min.
Step 4: Repeat Step #2
Step 5: Plug in charger and wait about 20-30secs. :fingers-crossed: If all went well it should go to the battery charging icon or menu or whatever you want to call it. If it does, let it charge for about 5min and fully power it on.
Congrats your phone is now on and past the black screen. :good:
This will temporarily fix the black screen problem. Well... not fix but at least get past it and have your phone on. I suggest you never fully power off your phone and use power off and restart in power option instead of power off. To fully fix it do the following Steps:
Step 6: Power off phone by holding power button until power menu pops up, and by selecting power off. When phone is fully powered off, plug in charger and wait about 20-30secs and see if it goes to the battery charging icon or menu or whatever you want to call it. If it does then proceed to Step 7.
If it does not and just sits there at the black screen, you will have to complete Steps 1-5 to get you phone back on again and retry Step 6.:crying:
Step 7: Let it charge for about 5min and fully power it back on.
Step 8: Power off phone by holding power button until power menu pops up, and by selecting power off. Now power on phone again and see if it powers on WITHOUT THE CHARGER. If so proceed to Step 9.
Again,:crying: If it does not power on and just sits there at the black screen, you will have to complete Steps 1-5 to get you phone back on again and repeat Steps 6-8 again.
Step 9: Power off phone by holding power button until power menu pops up, and by selecting power off.
Step 10: Hold power button until phone flashes lg logo, then goes completely black(not the dim lighted black screen, COMPLETELY BLACK). As soon as it goes completely black, let go of the power button and wait for your phone to power on.
If you phone powers on it should be fully fixed and should power on and off normally(well at least for me). But AGAIN *sighs* If it does not power on and just sits there at the black screen, you will have to complete Steps 1-5 to get you phone back on and repeat Steps 6-10 AGAIN.
I recommend you just do Steps 1-5 to get your phone on and past the black screen. And to use power saving technique's to save battery when not in use of phone or when not near a charger. I may make an YouTube video on how this "Completely Stupid Time Consuming Trick" is done. But anyways this is what I did to fix the black screen issue. Let me know if Steps 1-5 at least gets your phone past the black screen and on. Steps 6-10 is pointless but worked for me but time consuming.
Problem fixed

I'm having a similar problem. But all I have done is rooted with RootOptimusG.bat and then used the freegee app from the play store to unlock. I then power off my phone and when i turn it back on all i get is the lg symbol and then a blank screen?

Hello,
I'm currently on Nocturnal Limited Edition rom. But this has been happening to all the roms Ive flashed to this phone. When i fully power off my phone or the battery fully dies, and i try to power it back on, the lg logo flashes then it just sits there on a black screen not turning on. I have to do this stupid little trick to get it back on(plus in the charger and let it sit at the black screen for 7min, hold power button and plug out charger until phone powers off, hold volume up and down then plug in charger and let it sit for 6min, hold power button and plug out charger until phone powers off, then plug back in charger and BAM mysteriously the phone powers on). Its frustrating doing this trick everytime i mistakenly power off or when the battery fully dies. Basically i have to keep my phone on all day with all these power save techniques i do. the only way i can actually restart my phone is by selecting power off and restart, rather than power off. My point is how do i fix this? how do i get it to boot up? i cant even get into bootloader because it wont power up. thanks in advance. :victory::victory:

Edited first post
still cant get mine to restart. it sucks
I can get into download mode, after that it wont come back to life.
Any other help anybody can give me?
Thanks
I once upon a time have this kind of problem, solution below
What i did was remove the back panel, unscrew battery screws unplug battery & keep it unplugged for 1-2hrs or 5-6hrs. Then plug back battery with screws & back panel.
Its back to life !!!!!
I would suggest to take this to at&t replace & if outside usa this is the only possible solution for now.
Let me know if it works for anyone.
I tried the battery pull and it didnt work. Thanks for the idea.

Well the first time I tried it it failed and got stuck in download mode, after many more tyies and a different computer it finally worked.
After it rebooted it said the battery was dead, so I had to have it on the charger for a while before it would start.
I hope itworks for you on the first try.
I was stuck on this screen after I flashed 2 back to back roms....I tried recovery mode download mode connected to usb to no avail.So I found this post.I let it charge on the black screen for 10 min unplugged it powered it down with volume down and power button and i held down volume up and power and it booted up with the animation for the 2nd Rom I used.Long Story Short battery was dead smh
I can't get mine into recovery, it won't work.

I can get it into download mode, but after like 3 seconds the screen goes black also, and the pc dont reconize the device at all.. if i plug the usb in.
any suggestions, ive never seen this before.
How is your battery? Was the phone rooted? What was done to cause this?
Sounds like a stuck power button. Try tapping the power button quickly a bunch of times. Or try flicking the back of the phone by the power button with your finger.
