[Q] Problem booting into Recovery

So.... Been playing with this for the last two days trying to root this phone.
I've rooted a few other phones, so I do have experience with the overall process, but I am unable to even boot this phone into Recovery. I have tried booting into recovery by holding down both volume buttons + power and from adb terminal "adb reboot recovery."
Neither method works. The phone will boot (or reboot from adb) and brings up the "at&t World Phone" screen and then nothing else appears. The first time I tried this it actually wouldn't boot up even after pulling the battery and trying to start normally, it still sat at the same screen. I let it sit all day today at the screen until the battery died. I was finally able to get it to boot up earlier.
If anyone can help, that'd be greatly appreciated. Let me know what info I need to add.

I usually just press and hold both volume buttons and power then release just the power button and keeping the volume buttons still pushed on the 2nd time the white at&t screen pops up... Works for me every time.

hold volume up+down and power key btw this is wrong section to post supposed to be in general

Oh sorry, didn't realize it was supposed to be posted in general.
I've tried the Volume Up/Down + Power and this does not work, as I stated originally.
I've also tried to do it from the adb shell, which also does not work.
Does anyone have any idea why I can't access recovery?

I"m having a similar issue. Holding volume up+down and power and releasing in any combination just boots the phone up. If I just hold volume up+down and power the phone alternates between the AT&T World Phone screen endless.

Yes u have to let go of the pwr button when the phone screen turns on

I've tried just about every combination of the Volume Up/Down + Power and no luck.
I've also tried the following ADB commands, with no luck, it just reboots the phone:
adb reboot recovery
adb reboot-boatloader
When I hold Volume Down + Power I get the a Yellow Triangle with a Android guy with a shove with the text "Downloading... Do not turn off Target!!!"
When I hold Volume Up + Power I get an Android guy with the following text: "POWER RESET or UNKNOWN UPLOAD MODE"
For kicks, I tried to to flash a rooted update.zip via the Volume Down + Power way with the Samsung update software, the same way I have done with the Samsung Moment. Wasn't sure if it'd work, but worth a try.
Any one else have any ideas or suggestions?
Phishie, do you have a final release version? Or anything special about the phone you have?

I just press the two volume buttons first (to make sure theyre pressed before you hit power), then press the power button, as soon as the screen turns on, I let go of everything and it works just fine, no need to have ridiculously complicated instructions.
The trick is to make sure both volume buttons are pressed BEFORE you hit power. Then release. Easy as pie

Also, if you guys are having too much trouble, just download the one click root/unroot. It will run, boot your phone into recovery, then all you have to do is scroll to install packages with volume key and hit power. Done.

Trust me, I am making sure I'm pretty the keys completely. I've literally tried it fifty times by now.
And I've also tried the One Click Root. This does not boot the phone into recovery either. It just sits at the AT&T World Phone screen forever and will actually get stuck here and will not boot up normal even by pulling the battery and powering it back up. It'll just get stuck at the for-mentioned screen. I have to connect it to adb and reboot it there to get it out of the loop it's stuck in.

that doesnt sound good. Maybe you need to try a factory reset? are you running stock rom and everything?

When I first got the phone I did a factory reset.
Yea, it's completely stock to my knowledge. But I have a different ROM than the final release version that everyone else has. This is a pre-production device.

same problem
I try all the combos as well, no luck, would the combos be different for 2e vs 3e recovery?
I try combo, it powers on, the same thing happens, the at-t comes up, goes for a second, then screen brightens, wait a bit and then the home row buttons light up, hangs there... doesnt matter which kernel or which rom I flash, same thing, adb and other stuff wont work as they need usb debugging enabled, which mine isn't.
Is there a way to mod the phone files and flash to enable usb debugging? Anyway to remap the buttons to 2 button vs 3 button?
Everyone post your methods for entering recovery please?

[Q] Any chance of recovery from bricked state?

I was upgrading to Cog 9.1 using 2e recovery and I think my captivate is now bricked. It does not display anything (only black screen). Even after connecting to USB I do not see the battery charging symbol. Is there anyway out of this mode?
I have tried all the different key combos to try to get into download mode. I could always get into download mode earlier using down button + power button combo.
Any pointer will be very helpful.

How did you flash, and when did you realize there was an issue
Captivate
Cog 2.2

I flashed using ROM manager and I realised the issue after the screen remained black for around 30 mins.

the volume buttons and power combo are used to put it in recovery. Mine got stuck on the at&t logo. I pulled the battery after about 40 minutes, turned it on into recovery, wiped my data, rebooted, then worked flawlessly. My advice -> pull battery, put it back in, hold volume buttons, then connect the usb while continuing to hold up/down volume buttons, this should get you into download mode.

This sounds like i9000 rom button combo. Won't work with COG. For recovery hold both volume buttons and hold power button in. When at&t logo shows up, wait about a second and release the power button but continue to hold the vol. buttons. Should get you there.
For download, hold volume buttons down and plug in usb. Should put ya right there.
If you have a cappy that has the no buttons bug, you're pretty much hosed.
Designgears has a thread in the development section about the 3 button issue, with a mod that fixes it. Give it a read.
If you had usb debugging enabled and the computer sees the phone, you should be able to use adb to reboot recovery or download too.

[Q] No really, I bricked it...

OK, I've been reading here for 6 days all manner of Captivate unbricking. Here is my story...
I picked up a Captivate on the Rogers network. I connected it to my email server (Exchange 2010) with no problems, poked around, noticed the lag, noticed the SMS time issue, then promptly rooted, installed clockwork, and then threw cognition 2.2 beta 9.1.3. Quite frankly I was shocked at how much faster it was.
Anyways, after a day of poking around, I could not get my email to my exchange server running (tried the email.pak floating about), so I actually decided I was going to go back to the backup I made of my phone using clockwork before I installed cognition. When I restored my backup, I thought I had bricked my phone.
I let it rest for a day, then came back here, and found one of the 3-4 different variations of the 4 button download mode combo that permitted me to do the 1 click restore. This restored me to the AT&T version of 2.1. It worked, but was less than desirable.
I decided that at that point I really wanted to go back to stock, so I downloaded the stock backup on the Rogers Captivate wiki page, and did the restore using clockwork. The phone has not been the same since.
When i turn it on, I get an at&t splash screen, then in about 20 seconds I get the at&t "jingle", but the splash screen stays on. I can't seem to find any key combination that will permit me to get back into download mode so I can restore using the One Click that worked for me the first time. I have tried:
1. 3 button salute with USB in first, battery out initially.
2. 3 button salute with USB plugged in *as* I was inserting the battery.
3. Power and volume down (both with and without USB, and with battery being plugged in after USB and "during" insertion of battery)
4.Power and volume up with same combo's as #3.
5. Just volume up and volume down with same combo's as #3.
In all cases Odin was running before USB connected, running as administrator. I'm running 64bit windows, but I'm sure I have the correct drivers because I did this the first time with Odin and download mode and I haven't added or changed anything. But just for arguements sake I did uninstall, and then install the drivers again.
Any combination of power and volume buttons just gives me a battery charging logo. Occasionally when holding up until the second black screen I will get a quick indication that the computer might see something, but it dissappears withing a handful of seconds showing it promptly removed.
I'm downloading the Android SDK in the hopes that when I get the normal at&t splash screen after the "jingle" that something might actually be running in the background and maybe I can adb reboot download it but I'm not holding my breath.
Anyone seen this that has managed to get out of it? I'm starting to think the "unbrickable captivate" can be bricked. Assuming it is bricked, short of taking it back, is there anyone on the internet that can jtag these and in some fashion bring back to life?
Cheers,
Tim

and download mode is easy.
1. start odin3 and have data cable plugged into the computer
2. insert proper files if needed
3. hold volume up and volume down for 2 sec (no power button needed) then insert usb cable, continue to hold volumes till either the download mode screen pops up or odin3 sees the phone(if you bork the phone bad enough you can corrupt the download mode image, i did it with the not to successfull manhatten project kernel) but despite the screen being black it very well may be in download mode.
4. start flash
5. if it doesn't work send it to me ill find a use for it
alternatively if the phone can go passed the splash screens and boots fully you can adb reboot download. just get the development kit and drivers on your pc.

just to be clear, you are holding volume up as well as volume down starting with the phone being powered down and continue to hold them after you plug in usb untill something shows on the screen?
if your phone is not seeing the volumes buttons you are one of the very unlucky few that had a problem at the most inopportune moment.
there is also a way where you hold all three buttons till the phone reboots twice, or something. let me try it and ill give more specifics.

Pull the battery, open odin, plug usb into computer, hold vol up and down, plug usb into phone still holding vol buttons, drop in battery still holding vol buttons, when dl screen pops up and yellow com port lights up in odin release volume buttons. Do not touch power button at any time
Swyped...and sorry I don't proofread

Have you tried rebooting into recovery mode instead of download mode? Stock recovery is adb-ready and you should be able to adb reboot download. Its a long shot if you're having problems using button combo to get to d/l mode, but it's probably still worth a shot at this point.
If you were able to use 3 button combos before all this happened, and did NOT have to install the 3 button combo fix, its strange you don't have access to it now... Could restoring a Rogers Cappy to AT&T stock be the problem?

Yes, that's exactly correct. I do this:
1. everything pulled (battery, USB, sim, sd)
2. Open Oden (1 click)
3. Install battery
4. hold down (and keep holding) volume up and volume down
5. insert USB cable
6. depress (i.e. don't hold) power button
Goes straight to battery charging indicator.
If I swap #6 with holding the power button down, it continually reboots while just barely showing the battery charging indicator. I've tried letting go between black screens on the 1st, 2nd, 3rd, 4th, and 5th black screen. Still no android dude with the shovel.

Try all the steps you stated but not the last one where you press the power button. Don't press the power button.

Pull out battery for 10 seconds, hold volume up + down, connect usb into other usb port.

Trying to get into recovery mode gets me the at&t logo and the "jingle", but no recovery mode menu to reboot, etc.
This is what I'm worried about, restoring the Rogers stock over top of the Odin 1 click restore (which is an AT&T image) has bricked it and prevents download mode from invoking.

I know, I played with adb before I bricked it. ADB needs to "see" the phone, it no longer sees it (I have three computers, all three can't see it, but they can see my friends cappy with no problems first time, every time). Same process for his phone works every time to get into download mode, but not on mine.
And yes, have tried other USB ports on the same computer, both on the mainboard, and on the front ports.
Keep the ideas coming though please, I will try every one.

There's a trick to prompt download mode through a "jig" which you can hack together for about $2 in parts and a sacrificial microUSB cable...it works on the other SGSes, but I think it should work on the Captivate as well. Never tried it personally...

I work in a tech shop so have access to electronics, sacrificial cables, soldering irons, resistors, caps, etc.... could you point me in the right direction?

Oh, nevermind, found it in the i9000 forum. Will test first thing in the morning!
Cheers,

I bricked one today as well. Exactly what you are talking about here. The only thing is that i was still under the 30days so i swapped it out for a new one. As of right now ive been debating whether i want to do the voodoo fix (which i think is what bricked it to begin with)

[Q] Help me turn my Captivate off!

So here is the situation:
My power button is non-functional. This happened before, and I was able to press very firmly on the power button to access a shut down menu and turn off the phone. From this, I was able to enter download mode (pressing volume button while inserting USB) and go back to stock, which surprisingly, fixed my power button. I thought this nightmare was over.
Now, my power button has stopped working again (ICS hacksung 5.0). No matter how much pressing, prodding, whatever, I cannot get the power button to turn off the phone.
I cannot find any adb commands to turn off phone.
"adb reboot download" simply restarts the phone, no download mode. (adb does recognize the device)
If I take out the battery, as soon as I put it in the phone boots up.
If I am pressing any of the volume buttons when I put the battery in, I can access recovery mode (But cannot select anything because power button is still broken)
Any ideas? I doubt my phone is still under warranty (1.4 years old) and I do not have mobile insurance.
Thanks for any help in advance

Depending on what recovery u have (cwm or ?), U can use the capacitive buttons, while in that revovery, to navigate and select the power off option.
Sent by XDA Premium App

Thats a neat tip that I didn't know about, but I can't find any option to power off? Sorry for being retarded but I have given this time I promise
cwm recovery is what I have installed atm

Reboot to CWM and Power off option may be at the bottom of the 1st screen that u come to. That is dependent on what version of cwm u have though.

Quick boot from the market, you can place a poweroff button directly on the home screen

The ICS ROMS CWM recovery doesn't have power off choice, so he can't do that.
Sent from my SGH-I897 using xda premium

Unfortunately the quick boot "power off" option simply froze my phone, or restarted it.
I let my battery drain so that I could get a dead phone (that part worked), but when I hold my volume buttons and plug in the USB for download mode it goes to the "battery" screen or (if both are held down) recovery. No download mode.
In recovery "key test" the power button fails to register any key press, but it is not spamming either. This seems like a hardware problem, but I am not sure how it was fixed when I flashed back to stock before if that is the case
I will next try making a download mode jig, I'll let you guys know how it goes...

My cousin had the exact same problem less than a month ago.
I see you tried reboot download through adb, have you tried it using the same command, but using android emulator from market? That worked for her phone so worth a shot.

its a far shot but odin is now available for use on the phone itself and works on our phones. maybe you can find a kernel thats had the buttons reconfigured. i know darky has one somewhere.

Thanks for this idea, when I use

#reboot download
the phone simply reboots. Same thing happens in "Quick Boot" 's "Bootloader" reboot option. This phone just seems broke as hell.

Firstly, this power button problem is a lot more common than you would think. It is most often a hardware failure - I mean the button mechanism (springs etc. just dies). Google it to see how common.
Your post suggests a clue: If just putting the battery in reboots the phone, then the power button may be stuck in the "in" position.....so it is always getting "pushed". Then anything you do would mean ht epower button is already being pressed. If this is the case, you will never get a software solution ???
Also, I absolutely do not mean to be nasty. But if you search both Q&A and General sections there are previous threads with this button problem. Many other solutions have been posted and it will be difficult to list them together.
Finally, you can actually replace - yes, replace - the button yourself. Google/you tube has it.

Power button is broken? How to reboot to download?

Power everything was working this morning
Noticed that my power button wasn't working...the screen stayed on. Pulled battery, put it back in and the phone booted without pressing power.
Was like "wtf?"
When it booted, I couldn't turn off the screen.
So I just left the battery out and took it home.
Put a new rom on phone, thought "This will fix it."
Wrong.
Had to flash using Rom Manager because in recovery the power button doesn't respond.
When it began to boot "AT&T Screen" wouldn't disappear and show me some Doc's v4.
I can manipulate it to boot into recovery but the power button doesn't work still.
I can NOT get it to go into recovery.
Can someone helps me?

have ODIN open, and battery removed from phone... hook up usb, hold both vol keys, while inserting battery... you should get download mode fine even with a busted power button... what you do next is up to u....

Once more, I can NOT get it to boot into recovery in that fashion.
I cannot place batter in the phone without it attempting to boot
(doesn't not get past the AT&T boot screen)
I cannot plug it up, hold volume buttons and then put in battery because it will just charge. If I unplug the phone, the phone still thinks it's charging actually.
My question really is Can I 'fix' the power button, or can I reboot it into download mode through command propt? I've never used ADB to access my phone, so that'll be new.

Dude... recovery is useless right now, you have a busted power button... and because of 'said busted power button', none of what you're trying to do is going to work... like youve said...
You are down to trying to force download mode with USB cord, holding the vol keys, and inserting the battery... ADB cannot run commands to a phone stuck at the boot screen... Thread title says, how to reboot to download, and with the button like it is, all you can do is what i've posted...
As to fixing the power button, i don't see why that's not possible... do u feel it press at all?

Yeah, it 'presses' and 'clicks'. I mean it worked most of the day, it got low on power and it just quit working.

Any luck forcing download by puttin the battery in while the usb is hooked up with the vol keys pressed in?

I was having the same problem with my power button and eventually the power button stopped working completely even though i could still hear it click. I sent it to mobiletechvideos and they fixed it really fast and it was a great price.

goes into boot-loop like if I were holding the volume up/down and the power together. That's what doesn't make sense.

And I could buy another used Captivate for $50. I have an upgrade in less than 3 weeks and this happens

It happened to me once before after flashing a bad kernel. I just did what B-Naughty had suggested. Remove battery -> plug in USB -> hold both volume buttons --> then insert battery. Put me right in download mode and Odin it back with a working power button. Unless it's really a hardware problem, then you're out of luck...

Oh in that case imo i would get another used captivate and wait for the sgs 3

Maybe if I went to a store and sucked up to them they'd let me upgrade a month early (especially since I was initially supposed to upgrade in October)

Might be down to getting/making a USB jig if it don't come up... but if you upgrade to gs2, the jig will work for that model as well so won't be wasted...

Maybe a jig would work. But easier, funner solution is adding a line for a Moto Atrix 1 for just a penny plus the $36 fee. Problem solved. Thanks for the help for what could just be a hardware failure. I'll upgrade my other line later when the SGS 3 comes out
