[Q] Galaxy S not booting, black screen!

Firstly, may I apologise, I know this has been covered, I've trawled the internet for hours but just can't seem to get an answer.
I recently updated my UK, unlocked Galaxy S to Froyo via the registry hack, all was fine (ish). Because Froyo had been delayed in the UK and wasn't as great when it was running on my phone I thought it would be safer to revert back to 2.1 and wait until the official UK release came out (I know some will ask me why I did this, I just felt that Froyo was held back for a reason and I couldnt get an answer as to if I could update to the UK version if I already had the Scandinavian one). So I did the reg hack again and was offered 2.1. Everything seemed to go smoothly until the phone rebooted after downloading from Kies. Now the phone's animation starts then the flashing S symbol displays for an extended time. After that, the screen goes black. If I touch the two touchscreen buttons they stay on but do not go off. If I hold the power button the phone turns itself off and when the phone is powered off and I plug it into my PC with a USB, the battery charging sign comes on.
The phone was rooted and I did have the OCLF on but uninstalled that and un-rooted before changing the firmware so it was back to stock.
Before I get 20 people telling me to put the phone in download/recovery mode I must tell you that I can't. My phone has never been able to do it. I've tried every single way and button order suggested. I'm not the only one who's phone won't do it either so it's not just me. The only way I ever saw recovery mode on my phone was when I used the one click root on the PC.
I'm at a total loss. Debugging was turned off because Kies won't let you do anything with it turned on and so ADB recovery is out also.
Please help if you can.
Many thanks,
Ryan

Boot to download mode, do a repartition with Odin and 512 pit flash, remove battery and boot again to download mode and then do a odin firmware flash to which ever firmware you want.

thanks intratech but I can't boot the phone into recovery or download mode (sorry should have stated that). Believe me, I have tried every combination. I did a lot of research and discovered that there are quite a few people for whom that feature was disabled.

if the 3 button combo is not working on your phone, you should not do these risky stuff actually

thanks Noobproof. I remember coming across that thread last night. Although I consider myself ok with software, soldering and slicing just isn't my forte. I haven't got a clue about soldering, etc. I've just come back from the Carphone Warehouse (Samsung suggested I go there as they are the service centres listed on the Samsung UK website). The engineer had the phone for half hour and said that the "board was faulty". Haven't got a clue what he meant by that, unless he meant the internal SD which a few people have had go on them. Anywho, he told me to ring Samsung and send it in for a repair. I did that and need to send my phone special delivery to a company called regenersis in Scotland.
I knew rooting and flashing custom roms was a risk, that's why I never touched Odin,etc. I used Kies to upgrade to Froyo and Kies to downgrade back to Eclair. You would think that sticking to official Samsung software would be safe. I must admit, when it was going well I loved my Galaxy but more and more I'm starting to wish I'd opted for the Iphone.It just seems that there have been so many glitches and bugs, I mean, why should there ever be a need for lag fix in the first place? I often found myself keeping my fingers crossed when downloading simple apps as that was usually touch and go!
Feeling a bit deflated now. Was hoping some clever boffin had designed a software solution that would recognise the phone and force it into download/recovery mode.
Ah well, thanks for taking the time to respond anyway.
Best wishes,
Ryan

You know i was very happy when i for the phone for the first time and while i was doing a research (i live in turkey and there is no stock android market here) i came along this forum. And i have learned that i havent got the 3 button combo. I downloaded the 3 button fix abd took the phone to samsung centre.
They told me that they cannot flash it and i made a huge fight then they accepted and i have my 3 buttons. Never give up your phone. I dont think the internal sd is faulty it is just corruppted if you can access the recovery menu you could fix it. Any way you have to find a service centre that has an anyway jig box other a jtag box otherwise they will have to replace the motherboard. Good luck

I had the same problem all i did was use a different firmware .. didnt choose anything in pitfile and did not check on repartition but checked only F reset and Auto reboot and flashed my phone and voila it booted perfectly fine
Hope it helps others with black screen problem after booting
thanks
mike

I had the same problem too. This method really works.

Disconnected from PC in the middle of Odin restore-phone wont' boot.

The USB cord was removed from my phone in the middle of an Odin restore (it was stuck at factoryfs.rfs). Now the phone won't boot and it isn't recognized by my computer when plugged in. Did I find a way to brick this thing? Any help would be appreciated. This is my fourth Captivate and I'm sure AT&T is going to start to give me a hard time. Thanks.

build a jig or buy one on ebay. you need to get into download mode and reflash to sotck.

Try all 3 methods to get into download mode first

yes, you can try the key combo first. but as i know, build 1010 or later wont work for the key combo.

Got it back to d/l mode. Now it's stuck at factoryfs.rfs-same as last time. I'm finished with this phone. AT&T can send me another. This is what happened to the past two phones. Stuck on a Odin restore and can't get it up again.
Edit: Just booted up. That's a relief. Thanks.

If it had happened on more than one phone, you may consider looking at odin...maybe remove and reinstall our check your drivers or computer...just double check all of little stuff that might be so obvious that they are not obvious

so if your potentially bricking the phones, what do you tell AT&T that happened? and do they not ever check or whats the deal?

As far as I know at the wareenty centers they check for physical and water if they do attempt to boot as long as nothing looks custom they wont bother with checking the recovery or key combos samsung takes care of the rest they just want functional hardware..oh dont mention anything about modding. If anything syncing crashed is the best explaination. Tested.

Sorry I'm late getting back. My phone is up and running again. Got in to D/L mode and flashed back to stock. Got stuck on the AT&T logo, but used Odin one more time and it booted right up. The first time I brought in the phone, the tech took it to the display for 2 minutes and called the warranty dept for me. I think that it helped that the Chiefs playoff game was on. They didn't seem to want to be bothered! The phone rep asked about water and physical damage. No questions about modding. The second time I did it at home over the phone. Again, no questions about modding. I told the rep both times that I was trying to transfer music to the phone via Kies and it crapped out on me. It always help to play dumb and act like you don't know too much.

I had the same exact problem when i was just starting to mess around with roms and my biggest issue was the sequence that it took to flash properly. i kept opening odin then putting my phone in download mode and THEN plugging it into use as opposed to how it should have been which is holding vol up and vol down pressed then plugging in usb.

That's the weird thing. I'm somewhat new, but have been flashing my Captivate since Sept. When the original Cognition came out I was flashing daily. I think my problem was, it took longer than usual to flash to stock, I got impatient and didn't realize I could get to D/L mode by taking the battery out, holding power and inserting battery. I always used the button combo. Live and learn.

same problem
Ok i have the same problem as the original post stated, running odin and disconnected right at the beginning of the rom flash! this phone wont power up, and my jig (which i have used before) will not work! Is it done for!?

Ur last hope lays in adams Am I bricked thread, where u'll find an app that checks what state ur phone is in (linux or ubuntu needed)

nevermind, I tried harder and the jig worked, its one of the homemade jigs, where you cut up your charger, and use resistors to create the circut . . . . jankety but i got it to work thanks anyway though

Glad you got it, but I would buy a jig and keep it in a drawer. Just in case.

[Q] stuck power button? boot screen loop

Hi,
I am running a custom ROM (Darky's 9.5) on a rooted Galaxy S with Voodoo Fix. All has been fine for the past week since I changed to this ROM.
However, today, suddenly the phone switched off and then immediately turns on by itself and as soon as the Galaxy S screen appears it restarts again and the loop continues.
I removed the battery, but as SOON as I put the battery back in, it turns on by itself and resumes the on off sequence.
So its IMPOSSSIBLE to get into recovery mode, it doesnt work even though I have it enabled. I can get into Download mode but it lasts 5 seconds as the phone switches off and back on.
I can connect via USB to computer in download mode, but like I said it lasts 5seconds.
Is my power button jammed or is there something sinister going on? lol
Doubt I have warranty as I bought it off eBay many months ago...
Thanks for any advice!

Here we go again yet another Darky broke my phone post .
You have no warranty full stop as you flashed a custom rom ..
Usual fix for dead Deadlys rom is flash stock Froyo 2.2 rom via Odin with pit 512 and repartition checked .
However as you cannot get to download mode i would try first factory reset .
Second three button download recovery jig from .
http://forum.xda-developers.com/showthread.php?t=819551
You could always ask Darky .
jje

Thanks for your response.
Don't know why the ROM would behave like this a week after being ok, perhaps an app has caused the issue to surface.
I cannot do a factory reset, the phone is in a continuous loop off switching on then restarting within 5 seconds. It doesnt get past the initial Galaxy S boot screen.
I shall get my hands on a JIG in a couple of days. Not sure how that will stop the loop but worth a shot I suppose. If that dont work, this phones dead isn't it?

UPDATE: SOLVED.
It resolved all by itself. Basically, I got fed up and I left it to loop back and forth from the boot screen....and after a few minutes I returned to the phone screen to find it had booted up fully to the normal desktop.
Very strange. I might just have a dodgy phone.

[Q] In a LOT of trouble!

So a few days back i flashed the serendipity VII rom on to my previouly 2.2 Cappy, and it worked like a charm... a day later i was experimenting with a few ROMS all 2.3, and they worked, and to my luck I flashed a 2.2 ROM (Cognition 4) (by mistake i might add) and there it was a complete black screen brick!
since then Iv tried various methods to bring it back to life, the 3button thing, the taking the battery out holding down the 3 buttons connecting the usb and putting the battery back in, then releasing power only... Iv tried to even get it JTAGed, which was a disaster since the JTAG guy tried and cudnt get the thing to show connectivity... ANY HELP??
I fail to accept that this is the end... Please HELPP!!!!!

just keep trying to get into dl mode by using other usb ports, a jig, holding buttons while battery removed and install battery then plug in phone, happened to me plenty of times but was persistant that it finally got into dl mode.

Try making a jig and putting phone in download mode then flash stock through odin -- do a search for jig in the captivate forums. It saved me many times. You can even make one for about $1.

If you had gingerbread then you may need to use the i9000 version of entering download mode. The key combination is different. Search around on the forum as plenty have already mentioned what it is. I just don't remember off the top of my head.

if it will not power on at all....it doesnt look good.

try holding volume down and power...see if that brings up download mode. a jig is only $8 shipped to your home and will work.
i had a similar scenario and a jig brought my cappy back to life!! ive had the same phone since september, the jig has saved me from at least 8 new phones

I have seen a black screen for download mode. The only way I knew I was in download was when I saw the yellow band appear in Odin. Open Odin, and try different button combinations that will get you into download mode until you see Odin recognize your phone.

I'm sure you've tried, but these are 2 other key combos. I've had that happen to me in the past and it can be frustrating.
1. volume up + volume down
2. volume down + power
3. volume down + home (softkey) then power (this is the one that worked for me)
4. volume down + menu (softkey) then power
Hope everything works out for you. If all else fails, I'm sure a jig will work.

I learned this in the days of old, when we were flashing the baked Froyo's. Don't know if it applies or if you've tried it already, but what used to work for me was:
Open Odin
Pull the battery out, put it back in...don't turn it on.
Hold the volume down button
Plug in the usb
At no point in the process should you ever touch the power button. For your Odin version, I'd recommend using the Stock Odin, get factory and then try flashing your custom Rom again.
(Edit: I say volume down because that's the current button to enter download mode with Gingerbread. It used to be Volume Up and Down at the same time.)

ok first this does not belong in the dev section! belongs in Q&A so thing will get closed pretty soon. also other than a correct jtag u cant recover with jig, button combo or voodoo magic. u just mixed a i9000 GB bootloader along with a captivate froyo secondary boot which the Cog4 ROM has. use search and i think you can find someone who offers a jtag service

Well, I've seen a few mention it, but I think your going to need to make or puchase a jig. Hit radioshack and get 3 100kohm resistors, about $1. The directions are all over the forums here. I'd be willing to bet that will fix you up.
Also, once in a while it may still be alive even though the screen is black. Like someone else said, go ahead and start Odin, then plug your phone into USB. See if there is any response from Odin. It's worth a shot.
Either way, it's good to have a Jig handy.

claim warranty.

you need dl mode to do that, he's not even getting power up. go to att store and say it wont turn on today gimme replacement.

How did someone with just 2 posts make a thread in here? I thought you had to have 10+ posts just to post in a thread.

just contact samsung the captivate should be in warraty untill oct2011.. i also bricked my phone while on serendipity VII see Q&A Soft brick or hard Brick.i had my phone stuck on the battery charge screen. was not able to get to download mode or recovery and my battery wouldnt charge . so i called samsung just gave them my imei number and they said it was under warranty until oct 2011. i did not tell them i bricked it while flashing roms. i just told them my phone wont charge or turn on. i sent my phone to the samsung repair center in dallas tx. my phone was fix at no charge even though i had it rooted and running a custom rom. samsung just fixed my looping battery screen and put there stock froyo erasing all my apps and data.it took about 2 weeks to get all this done. got my phone back this monday and everything is working great....
so just contact samsung and say the phone wont turn on dont say you rooted it or flashed a room. samsung wont check to see if its rooted all they care about is that you didnt drop the phone or something like that.

Same exact thing happened to me on my last phone. Your phone is dead, dead, dead. Hard bricked. Nothing will bring it back. Take it to an AT&T store and tell them you were upgrading to 2.2 and the screen went black and now it wont come back on.
There is no jig or JTAG that will fix it, trust me, I tried

at&t might help, but you have to hassle alot.Just contact samsung they will help for sure.i just sent them my bricked phone and they fixed it in two weeks at no charge. samsung will do it for free, im living prof.

I dont really buy into the fact that its dead, no way... its just that the revisions on the boot.bin and sbl.bin are different... shouldn't JTAG work? and cant claim warranty cuz im not in the US!!! there must be a way people.... im faar too poor to just give up without a fight!!!

[Solved] Slim ICS never loads past logo

I have been running Slim ICS on my Captivate for a month or two now. I have been on version 3.6 for awhile now and have had no issues.
Today however, My phone was acting a little odd, and I decided that it had been awhile since my last reboot, so I held the power button, clicked reboot, (not into recovery) put the phone back in my pocket once I was sure it was rebooting and went on my way.
30 minutes later I took my phone out of my pocket and looked at the screen. It was still on the Slim ICS screen and I thought maybe it was looping, but it never rebooted itself or went back to the AT&T screen. It just stayed on the Slim ICS screen until I pulled the battery.
It has done the same thing every time I try to turn it on.
Download mode wont work (my cappy doesn't have the 3-button combo, so I have to use a jig.) I can get it in download mode but my computers wont read it. I tried uninstalling/reinstalling drivers, I tried different chords (on each computer.) and nothing works.
I'm kind of at my witts end, as it is my alarm in the mornings and I rely heavily on my phone. any suggestions on what to do? or is it time to check if I can upgrade...?
(P.S. I apologize for the sloppy formatting, it's 2:30 am and I've been trying to make this work for 2 hours...)
EDIT: I kept trying and eventually got my phone to read as gadget serial instead of unknown, flashed back to stock and am now getting back to ICS. To anyone in a similar situation, just keep trying and hopefully it'll pay off.

Do you have recovery mode?

None of the button combos work on my device (none of them ever have) and I cant get my computer to read my phone, so I can't use ADB to reboot in recovery. All I can really do right now is get into download mode with my jig, but none of the computers in my house will read it with any of my chords.

Have u tried "Mobile Odin" by Chainfire ?? Find it in the Market...uuugghh...the Play Store. :/

alright, it was a huge headache... but I got back to gingerbread stock.
I'll tell how I did it:
Deleted all installed samsung drivers (and rebooted computer).
Go to download mode (I used the jig, if you have button combos, it's probably easier)
Plug the device into the computer and hope to god it reads as Gadget serial
I then used this to restore to stock (it failed 3 times before it worked... everytime it got just a little bit further, until it finished.)
So ultimately, after a nightmare of a time and a lot of headache, I'm thankfully back at stock, and working on getting back to ICS.
although the process is difficult, as odin still won't find my phone (heimdall does though)
