[Q] Black screen, brick? - Captivate General

I tried flashing the latest Cognition onto my captivate today using ClockworkMod but the phone appears to no longer start up. The phone just sits there acting like it has no power with a black screen. I've tried holding volume up & down while plugging in the USB cable. I've tried holding volume up & down while pressing the power button. I've even tried the 301k resistor usb plug. Are there any other methods I can try that I have missed while searching the forums?
Thanks in advanced!

Does your computer recognize your phone when you plug it in? If it does, try this
Open the one click root from your computer and click one click root if it should take you to clockworkmod recovery.

Change the usb port ?

I could never get the PC to recognize the device or even get anything to appear on the screen. Acts like it just doesn't have power. I think I'm going to try sending it to Samsung...

I doubt you are bricked. I had a similar issue where a ODIN flash failed midway through and I was left with a phone and black screen. There's a combination to get the phone directly into download mode which I tried. I THINK this is what it was:
Remove SIM, external SD card, and battery
Wait 10 seconds with battery out
Plug phone into computer (with battery out)
Hold Vol Up/Down + Power button
While holding the 3 buttons, insert battery
Release power button while holding Vol/Up down
Phone should be in Download mode
It took me a few tries to get the timing down, but it worked. The key combination might not be consistent with what others use. I think I've read somewhere that you don't need to hold the power button at all, I dunno. If you search, I know for sure there are more threads explaining the above method.
In regards to the 301k resistor, you might also want to try 300k or 302k. I know if you have problems finding these resistors, I've seen people hook up (3) 100k resistors in series from Radio Shack.
I also have a bunch of female USB plugs and resistors shipping to me on Monday. If you're still having problems by next week, send me a PM and I might be able to send you a jig to try out. If you send your phone into AT&T for warranty replacement, you MIGHT end up getting charged for the replacement. I've read stories of AT&T initially sending out a replacement phone, and then later billing the customer for the replacement since they were able to access system files and figure out the customer voided warranty by flashing a unsupported ROM.

[q] help! My phone wont do anything!

hey guys,
my phone litteraly wont do anything. i f*ed up some fonts using type fresh, then tried to restore using the odin3 downloader. i accidentally closed it, and now my phone wont boot up/react to any buttons pressed. any help? thanks guys!
had the same problem. i cant figure out how to even get odin working, it says one click but when i hook up it to odin it gives me a message that still doesnt tell me ****. i had to send my phone back for a new one and told them i used easyroot on the market bc i didnt know what it was and it sounded cool but now i know not to ever do that again that it messd up my phone. Praying to god that they dont charge my for anything
You should still be able to enter bootloader mode by turning phone off and holding down up/down vol and pwr simultaneously until boot screen flashes then release power button only
it wont even do that
open odin (use the stock one click version)
with the phone off (remove/reinsert the battery if need be) and not plugged in; hold vol. down and insert the usb cable (keep holding vol. down untill you see the download screen). this should put you into download mode and if you have the right drivers odin should recognize the phone.
I've stuffed my captivate on a few occasions and so far I have been able to use this method to get into download mode and fix it.
it wont do anything at all. it wont power on, show up in adb, anything... and stupid att wont do ANYTHING -_- oh well. any help would be appreciated!
Have any of you offering support to the OP actually had your phone in the described state? I've read a few posts where the phone is seemingly completely dead as the OP describes and no one says they've successfully recovered from that state. All I ever see is the same old button combinations/battery/usb shenanigans and statements of that should work and that the phone is unbrickable. I have personally seen a device that was behaving in such a manner and no combination of battery pulling, usb plugging, button holding, or tongue twisting would generate anything from the phone. The only thing the phone would do was get hot.
same here. Phone showed bright green screen...wasnt done with teh flash and said it was finished...now the nly thing I can get is power and hold the vlume up for some IRQ and hex stuff. I posted a questionthis morning but...serious. Vol up and down and any things else gives nothign but a black screen..battery out...back in anything..its torched.

Did you read the rest of the posts? The OP already stated several times that the phone does nothing. I realize that most people will say it does nothing or is "bricked" if it simply shows the "connect to computer" screen, but the OP has stated more than once that the phone shows nothing. Yes, everyone is trying to help, but simply repeating what has been said numerous times before doesn't help.
Has anyone actually recovered a phone that displays NOTHING? No logos, no recovery, no nothing.
Last night, i turned off the light in my room when i noticed a glowing from my desk. i walked over, and it turns out my captivate's screen was in fact on, it was just a faint black glow, and none of the power buttons would do anything. when i took the battery out, it shut off completely!
As I pointed out here
http://forum.xda-developers.com/showthread.php?t=757293
Im pretty sure it was my fault for not completely following instructions on the ext4 one click install root, settings.db etc so everyone needs to make sure if the dev says flash before..do it.
State of the phone was, it would not completely power on..therefor no usb drivers would load and Odin cannot see the phone and it can no longer flash..the only thing I could get it to do was show a screen with that text. I put in my post. I ordered it via letstalk.com so I sent it back and assuming they get the same result Ill have a new one hopefully by the end of the week. Im just glad I stil had my old iphone3 to slap my sim card in.
The odin one click flash thing..it just flaked right at the start it looked like..but I cant be sure because as soon as I saw a blue progress bar I stepped into the kitchen for abtou 30 sec..I came back and the screen was florescent green and Odin said it was done. I knew something was wrong as it was way too fast so I unplugged, removed the battery and set it back in...from there on out it would do nothing with the power button unless on a semi rare occasion if I hit the volume up button and power I got the IRQ stuff.
Annoying as I had a nandroid backup just before I started messing with it.
i just sent mine into samsung... back to mah ol trusty blackjack. gonna have to get used to supermario bros 3 instead of spyro....
ANYWAYS theyre sending me a new one!

Hey thanks, but i already sent it to em... thank you everyone for your help!
Just a note... i said before hold vol down and plug in usb. I had it in a pretty bad state tonight. Played around. Same idea as before, but had to hold vol up and vol down. If i brick a few more times, i'll give a better guide. But this phone can DEFINITELY come back from a state where you can't even get it to power on. Figured any additional info on this would be good.

[Q] Captivate powers on, but I get a black screen

So, I was trying to flash my captivate back to a stock rom using odin3 when it errored half way through. Now my phone will power on, but the screen is just black. No recovery mode, no download mode. Nothing. Is there any coming back from this?
Sounds like it may be time to make yourself a jig. Have you tried pulling the battery and putting it back in, then holding vol up and vol down when plugging in the usb cable?
If you haven't already, try taking the battery sim card and memory card out. Put only the battery back in. Start odin. plug the usb cable into your computer. Press and hold just the volume up and down keys. Insert the usb cable into the phone. Does that get you into download mode? If not, then do a youtube search for "galaxy s usb jig". It will take a little work, but you will get your phone working again.
I've tried all that except plugging in the USB while holding the volume keys. I'll have to give it shot. If not, I'll look in to that jig. Never knew what that was until now. Guess I've just been lucky, I haven't needed to know.
Wow. It worked. So simple. Thanks guys.

[Q] Infuse bootloop

Im trying to explain everything to prevent unneeded questions
I have viewed several threads about this but absolutely none with an answer. My Samsung Infuse 4g with at&t (nonrooted) is in a bootloop. The cause of this was my every-other-day reboot. Once I turned it back on it goes to the samsung screen for about 5 secs, then goes black, then says samsung again and so on repeatedly. I pull the battery and as soon as it makes contact back with the phone it turns on by itself into the same Samsung screen over and over. When plugged into wall or computer it will show the charge screen where there is no battery life left, then it will flash and start up the charge screen again and so on just like the samsung screen. I cannot go into download mode (the buttons, at this point, do nothing. No response)
I have tried taking the battery out and plugging in usb cable to computer, then holding both volumes and putting battery in=charging loop
↑ with volume up=charging loop
↑↑ with volume down=charging loop
computer doesnt detect it, adb cant find it, cannot go into download mode, odin cant see it, heimdall cant see it, cant actually boot into anything, cant leave battery in or else phone will restart itself the entire time, and this was caused by my (already gbread) infuse 4g doing a regular reboot (aka power button, tap power off, after phone is confirmed off take battery out, battery back in, turn on)
Recommendations at this point? on a scale from 1=noob to 10=expert im a 7 on this type of thing. Ive always heard that as long as you can boot into a picture its only soft bricked but if i was right i wouldnt be here. Any and all help would be much appreciated. If you need me to post a video I would have NO problem doing that showing everything im doing.
oh, and by I have viewed several threads about this i meant that i have only been able to find 1 thread about it and 2 links that didnt work for me but might for you
link that worked- http://forum.xda-developers.com/archive/index.php/t-1354731.html

You might have already tried this way, but I've always held down both volume buttons first before plugging in the USB cord - not the other way around. You can also try different cords, different USB ports and/or different computers.
Mine was doing this the other day and it turned out to be my SD card being flaky. Maybe try taking it out and booting?

Ive tried a hp touchpad cord, an atrix cord, and the original cord. I cant really do the button combo because as soon as the battery makes contact the phone turns on. thats why i had the usb cord in first to see if it worked. ive tried every usb port and 2 different laptops, the computer wont recognize it if the phone wont go past the samsung start up screen

I've taken the card out and used a different card, nothing. Tried taking sim card out, nothing.
I should have been clearer. Leave the battery out of the process until after attaching the cord and the screen coming up.

I do, every time.
1. battery out
2. hold down volume buttons (any combo)
3. attach cord (nothing happens, no screen, nothing)
4. put battery in
Results= Charging loop

should be the same...wonder if you battery needs to be charged first, it should be fully charged at best...to do any flash/Odin/one click
this how I do it...basicly the same..
>take batt out
>plug in usb cable...to both phone and computer
>hold both volume buttons...NO NOT HOLD THE POWER BUTTON....
>put batt in...
and bam should see the android dude shoveling in yellow triangle...
If you get no response from the usb without the battery, and inserting the battery indicates the battery needs charging - I'd suspect the phone's usb port. Especially after trying different cords & computers.

Hello.
I have the same problem... tried also everything now i gave it to cellphone shop, i hope you guys can give me answer before i am gonna waist $100
HELP?1
Help me please
I was in this state. There are two options I can think of. A JIG as mentioned previously or the Heimdall One-Click-Unbrick. The one-click unbrick did it for me and got me back to cmw and download mode, then i could flash to stock, root and flash up to ICS. It was really easy and I stopped sweating once it booted to cmw instantly after running it.
Joe
hello.
The problem is when i connect it to my computer its keep disconnecting and doing terreble noise, (windows noise) when you keep connecting and disconnecting USB cable
JIG DIDNT WORK, because the same problem.... maybe the chargging connect is broken? or has a corrosion?

Thanks ✟
Moving to Q&A
Sounds/Looks like a hardware issue...
Did it get any water damage in the past?
Hope you got warranty or still under warranty.
I am having exactly the same problem. My Infuse has never been rooted or unlocked (quite ironically, I was about to root it for the first time).
Boot loop when not plugged in, charge loop when plugged in. Absolutely no combination of buttons, inserting/removing the battery, and/or plugging/unplugging the USB has gotten it to do anything.
This has happened several times over the past few days. The first few times it sorted itself out in an hour or two. Today I couldn't get it to do anything at all.
I found several posts by people who have this problem, and it has never been conclusively solved from what I've seen. Finally one person said they fixed it by lightly smacking the phone with their hand. Lo and behold, it came on for about 5 minutes before looping again. So I smacked it again, and before it could re-loop, I factory reset it. A few hours went by and I was convinced that it was fixed.
A few minutes ago I had it plugged in to my computer via USB and was getting ready to SuperOneClick it. Then it went back into loop. I can't get it to come on this time. Again, no combination of buttons will send it into download mode. The computer can't see it. The battery is charged. The USB cable and port are fine. The software was reset earlier today. Does this mean that I have a hardware problem, or is there a software issue that could be fixable?
EDIT: So I decided to try hitting the power button, something that had never worked to this point, and the device came on. A couple minutes later it went back to boot loop. On a whim I tried download mode, which had stubbornly refused to work all day. Of course it immediately worked. Not really knowing what to try, since I'd already wiped user data, I wiped cache data and formatted the internal SD. Then I told it to reboot. Back to boot loop. A few minutes later, it came back on with the power button. Two minutes later, boot loop again. Then it restarted of its own accord. And now back to boot loop. I just don't even know anymore.
EDIT2: Just a thought... Something is weird with the power button. Whenever the phone is on and I hit power (briefly, not holding it down), it goes to the shutdown menu as though I'd held it down. A few seconds later, I'm always back in boot loop.
Infuse loop
I have found the problem. It is, in my case, the power button. I removed the case and crossed terminals with a paperclip. BAM. Booted up, and when I removed the paper clip.... back to boot loop at Samsung logo.
There is a place to send the phone. Ive see great reviews.
mobiletechvideos.mybigcommerce.com/samsung-infuse-4g-power-button-repair/
Seems like there has been a string of power button malfunctions going around lately. There are a few threads going on where people have had this issue. Sometimes its just the terminals needing to be cleaned or dust blown out.

[Q] Help! True infuse brick and loop

Hey Gang! I have a not so common issue, from what I have searched and read.
I'm trying to fix a friends Infuse 4G from looping at the Samsung screen. Also the phone would power loop when battery is inserted and charge loop when plugged into the USB Cable. Nothing I have tried has worked.
Tried:
1. 3 button to CWM Recovery. FAIL
2. Volume up/dn held then plug USB in for download mode. FAIL
3. Plug in the USB with no battery, hold volume up/dn, insert battery for download mode. FAIL
Ok... now being really familiar with electronics, I made a JIG from a tutorial and here is the fun part for those that want to help out....
I plugged the JIG in, inserted the battery and behold... I got the download mode screen... but it too is LOOPING!!!!
So I tried a quick switch. Inserted JIG, Inserted battery, got the download mode screen and before it looped, I replaced the JIG with the USB Cable. FAIL! It started looping with the Samsung screen.
I am stumped! Can anyone help out or know how I can get past this issue so I can Odin or flash back to stock without backtracking to what I have already done?
Thanks in Advance,
Scott

That's definitely a messed up power button. My power button is messed up also. About every 3 months, I have to just slam the power button on a hard surface and it goes back to normal. Just a quick fix if nothing else works or if you can't fix it.

I may suggest tapping it or taking it out for a cleaning.
Or replacing it or even remapping it..there are 2 threads in the general section that is relevant.
I don't recommend slamming it though...what is good or omar's phone may not be good for zero's phone.
Lol valid point. Hope everything works out for you tho. Some people have gotten their power button fixed for cheap..don't know exact prices.

[Q] AT&T One X not turning on

I bought a AT&T HTC One X form eBay,the seller had a high rating and good feedback and supports returning Non working items,so i just decided to buy it.
When i tried turning it on,it didn't at first,so i thought it could have an empty battery,so i plugged it in to charge it,it remained that way for almost 3 hours.
it's not displaying any signs of life;no LED to indicate charging,no vibrating when trying to press the power button,no sounds,nothing on the screen...
I tried plugging it in to my PC,didn't end well too,when i first connected it,the "installing drivers" notification popped up for about a second,then said "failed to install drivers",i went to Device Manager from the Control Panel,the port that it is plugged in though says "Unknown Device".
I've tried pressing both of the volume rockers and the power button for about 10 seconds,didn't work,as well as pressing both volume rockers with the power button individually,still nothing.
before i tell the seller about this,is there something that i'm missing?
It took a long time to arrive and well take a long time to get replaced,so if someones got a solution,that would be great.
Also sorry if this isn't the right place to ask.
The eBay post said that it was fully functional.
Firstly, don't go trying random button combinations when you don't really know what they do. The volume up + power combo is something you should never do, it's puts the phone into Qualcomm download mode and you don't want that. The only button combo you should ever try is volume down + power, which will boot it into the bootloader. Leave it plugged into an AC outlet for eight hours and try powering it on again, both normally and with the button combo. If it doesn't respond you've got yourself a lemon, but honestly it looks that way anyway.
Sent from my Evita
I left it plugged in to a charger for almost 10 hours,same thing,as well as the power button and volume down thing.
I've tried using the Cyanogen Mod Installer to see if it would recognize the device,it did,it's now downloading the Operating system,i'll stop it untill someone tells me if that's a good idea or not.
Personally, I wouldn't bother, I'd be returning the device straight away if it didn't turn on the first try.
