HELP! Bootloader unresponsive!

So, I was trying to flash my NS back to stock from TWRP becuase my power button's broke and I'm sending it in.
Anyways, TWRP crashed during flashing (wow....recovery crashing NOT good), and I cant boot the phone except by plugging it in from being off. However, when I hold vol up and get to bootloader by doing that, the bootloader is completely unresponsive to vol presses, and my comp doesnt see the device.
This is NOT good. But I'm clueless as to how to fix something like a bootloader issue. Anyone?

I would try odin. Search around the Samsung webiste they should have an exe which flashes the phone back to factory default. I've seen one posted around here but it depends which version of the phone you have.

Odin requires very careful use. DO NOT CLEAR YOUR EFS!
It may be your only option though.
If you can jimmy your power button and get into the normal bootloader then follow these steps:
1) install Ubuntu
2) install Android sdk for gb or ics whichever you are using
3) install fastboot (download it from cyanogenmod wiki and copy it to Ubuntu's sbin folder)
4) in bootloader menu, connect USB, then in Ubuntu terminal type fastboot reboot recovery (may be reboot-recovery, can't remember)
You should be able to use your phones capacitive buttons to navigate the menu and install a stock ROM

Yeah. Totally forgot you can do that. Try what he said.

Problem is, fastboot doesn't work. The bootloader is completely unresponsive.
It's like it launches into a crash. I can see the options, but the vol buttons dont do anything. However, those buttons work, otherwise I wouldnt be able to even get THAT far.
I'm trying to get the power button to register a press (it randomly does, but Ive had hours of no luck).
Any other ideas? Why would the bootloader launch into a crash. I wonder if it's because the phone is being turned on via power cable instead of the pwr button, but that seems unlikely.
On a side note, I have my efs backup from when I was using 2.3.7, so I've got it handy if I can ODIN the thing, but I dont know crap about odin.

Read his response again. I don't think you understood what he said. You can initiate those commands through your PC instead of pushing the buttons.

Sorry, I should have elaborated more.
I have tried on both my PC and Mac (via terminal app) to see the device under 'fastboot devices' command. No devices show up, so it's not even seeing the thing. Neither computer sees the device as being hooked up, as far as I can tell.
It'll boot into the unresponsive bootloader when I plug the cable in and hold vol up. At that point, nothing else happens. Doesnt show up on fastboot, etc.

sounds like your power button went. thats the #1 complaint i read about the power button going, the unresponsive volume buttons. my power button is gone to(will register a response every once in a while, on its own. my volume buttons dont register either when in the bootloader. but, i can get them to register. what i do is take the battery cover of, and gently flick the phone with my fingers right near the power button, but on the back of the phone. most the time, the power button will register that i pressed reboot bootloader, but, sometimes it allows me to select up or down with the volume keys. if it reboots bootloader, i just try again. ive got it down to an art since im in the bootloader often, it takes me about 20 seconds to get the volume keys going up or down. at first it would take me 3-5 minutes. i hope that helps.

LOL simms thanks. I had a feeling you might chime in here since I had msg'd you earlier about my pwr button going out.
The thing that sucks is that I was just restoring it to stock in TWRP and it just locked up for some reason. I knew as soon as it happened that I was in trouble. I'll keep messing with it and see if I can get it to register 'Reboot Bootloader'.
I was actually wondering about that earlier. I figured that if the vol keys didnt work, then the pwr button wouldnt either in this situation. I know mine randomly registers presses, but now it's being a *****.
We'll see......

try going into the bootloader and give it a few smack on the back, see if thatll register and "press" reboot bootloader(since its the first option). the first time i went into the boatloader after my power button went, i thought that i was **** out of luck too. but, it turned out fairly very manageable with some practice. i usually flick it very lightly to get the volume buttons to move up and down, to hard and reboot boorloader registers.

[Q] Trying to root, cant get into download mode

Im following this here:
http://www.techzek.com/how-to-root-samsung-galaxy-s-blaze-4g-sgh-t769-smartphone/
But the power, vol up and down get it to show the yellow "warning" thing that im supposed to see, but it goes away after like half a second so I cant get into it. What else can I do?

how to get to download mode.
As you press the volume +/- and power button , simultaneously plug the micro usb cable into your phone (this cable should already be attached to your pc). This should do the trick.
Happy rooting.

The instructions in the first post are wrong, and should be updated. You have to have the cable plugged in. In the video for example, he has the phone plugged in the entire time. You're not required to have three hands in order to get it done.

I've had no luck with any of the variations on this method either.

Turn your phone off, hold both volume buttons and with your usb plugged into the computer take the other end and plug it into your phone while continuously holding the volume buttons. It will boot into the caution screen and than you press up to get into download mode.

If none of the above still don't work try this
1. Turn off phone
2. Remove battery
3. Remove sim card
4. Remove SD card
5. Plug in USB from computer
6. Hold volume up + volume down
7. While still holding the volumes insert battery
8. Should now be in download mode

Thank you both for the replies. I've tried both methods several times without success. I'm tired now so I'll quit for the night. I'll try again tomorrow a few more times. If I can't get it to work I'll take it as a sign that I'm not meant to root this phone. I must have tried 30 times today; it gets old.

Update:
I've tried this ten or fifteen more times. I'm finding that the yellow warning message, whatever it is, doesn't appear at all, ever, unless the USB cable is not connected when I put the battery in. If the USB is connected, I get the gray battery icon every time, no matter what else I do.
If I do connect the USB, with the battery out, I immediately feel the device vibrating every second or so, as if reboooting.
I tried removing the SIM and SD cards again. This had no effect.
It's very strange. In that video the entire process looks about as easy as doing a simple battery pull. It's just not working for me. Is it possible that Samsung made some of these phones "root-proof"?

Worst case scenario you will have to buy a Samsung jig.

I had to do it a few times myself.... It did not catch for me the first 3-4 times...
Then it worked. Make sure you are holding down all 3 buttons down tight.

I think I've tried it at least 50 times now, with variations, and it's just not happening. I freely admit my ineptness, but holding down buttons is something even I can manage.
By "three buttons", I take it you mean two. I don't have separate volume up/down buttons on my Blaze; just a single rocker button. That's what you mean, right?
I did get as far as the warning screen, but from that screen there is no option for pressing up to go into download mode, so it seems that my warning screen is different from others'.
I guess the next thing is to research "Samsung jig" and figure out whether this is something I can possibly do.

I went through the same thing, I too thought I had to purchase a jig but the method I posted thanks to another member saved me, try again with a modification to step 6
1. Turn off phone
2. Remove battery
3. Remove sim card
4. Remove SD card
5. Plug in USB from computer
6. Hold volume up + volume down + power buttons
7. While still holding the volumes insert battery

Thank you. I just tried it a couple of times, without success. I have to go out now, but I'll give it another few tries later.
If I have to get a jig, should the Samsung Galaxy S be compatible? I'd think so, but I don't know for sure.

This is a slight variation of what everyone is suggesting...I was also getting vibrations when trying other methods.
Turn off phone
Unplug battery
hold volume rocker, make sure you're holding down both up and down
Insert battery
Hold power button until the warning comes up...only takes a few seconds

I said three buttons, because it seemed (at least to me) that you need to hold sides of the volume button down at the same time. It does not seem to be just a up/down button.

Thanks for this suggestion, but it also didn't work.
This method, like some of the others, takes me into what I think is Recovery Mode. I'm not sure, because I don't really know what I'm doing. The message that flashes on the screen isn't really a warning. Doing it this way, i.e., releasing the power button but not the volume button after the phone starts, takes me to a screen that says,
Android system recovery <3e>
at the top. Then there are some options: reboot system now, apply update from sdcard, wipe data/factory reset, wipe cache partititon. I can use the volume button to select an option, and the "OK Key", whatever that is, to select.
Near the bottom of the screen, in yellow, is the text that I couldn't read before:
-- Verifying internal MMC block...
checksum confirmation -> check(0)
Not need checksum confirmation
already executed!!...
# MANUAL MODE #
And that's it. In the background of this screen, grayed out, there's a white triangle with a yellow exclamation mark in it and a little green android.
Is there a way to get from this screen to Download Mode?

I guess it might if I could get ADB to work. So far, no luck; but that's a whole different problem. There are pages upon pages of posts here from people having difficulties getting ADB to work, so it'll take days or weeks to sift through all that and figure out what I'm doing wrong.
I thought the actual rooting process would be fairly simple, and it would only get complicated when trying to install custom ROMS and that sort of thing, which I'm not trying to do. It appears that I was wrong. I think I just don't have the knowledge to do this.

Make sure you have Kies Air turned on when you try to connect. You can use USB or wireless mode then. I tried and without Kies, it would not connect.

So I should have debugging mode and Kies Air turned on, and then ADB should be able to find the Blaze? I'll try it tomorrow.
Thank you.

Get into bootloader

The easiest way to get into boot loader while phone is on. I see a lot of people posting different ways.
Reboot phone, either by pressing and holding the power button until the touch buttons at the bottom flash or just by hitting reboot within your ROM.
When the screen goes black, hold volume down.
No need to press and hold both at the same time unless your phone is powered off.
The advantage being you can do this with just one hand.

Download quckboot. That's the easiest way if you're already rooted.

Ah but this also works if you cant boot due to bad flash or something!

As this looks to be meant as general FYI, the following should be noted:
1) Many people that can't get into bootloader, is because lots of people instruct to just "hold power and volume down". Which, if taken literally, doesn't actually do anything. You actually have to release the power button (after holding it for a few seconds), while still holding the vol down rocker. which brings us to . . .
2) You have to keep holding vol down until the bootloader screen comes up. Otherwise, if you release it too soon, the phone will just boot normally.
3) If you press the vol down rocker too late, the phone will boot into safe mode. You need to hit it before the HTC boot screen comes up, while the screen is still black.
4) There seem to be a good number of posts by folks that can't properly get into bootloader, and assume its an issue with the phone. But 99.9999% of the time, its just user error (not doing the button sequence properly). Just follow the OP, and the points I've listed above, and you will get into bootloader. If bootloader was messed up in any way (corrupted, overwritten, etc.), the screen would not come on at all. So the problem is not the phone, but almost always user error.
The one exception to this might be an obscure mechanical problem, such as the volume rocker not functioning properly. But this if almost never the case.

The only real time you have to hold both down at the same time, is if your phone is already off. Otherwise so long as you press and hold volume when the screen goes black from a reboot, you will get in.

That's the best way. Most ROMs have a reboot function built in when you hit the power button

As OP mentioned, this won't help you if you are stuck on the boot screen. Which is one of the more common situations where noobs suddenly realize they don't know how to get into bootloader.

I always just hold down both power and vol down until the capacitive buttons stop flashing then let go of power but still hold vol down until I get into bootloader. Works 100% of the time

[Issue] Lumia 1020 Doesnt turn on after softreset

Hi guys!
I have a problem...
I bought my lumia 1020 on dec/25... two days later i was using the GoPro app and my phone frezon.
I did a soft reset but then... it doesnt turn on any more.
I Tried all combinations seen in the internet about soft/hard reset, all buttons pressed but nothing. Plugged in pc... it doesnt even point somenthing in USB.
Today, I plugged in USB and noticed that the middle windows light was on for a period... tried again the buttons procedure but nothing...
I´m from brazil and a friend brought it to me from England so... I dont know if i sent it to Nokia will do...
Plz, does anybody knows what I can do?
Thx!

All these descriptions assumes your phone is turned off. (hold down power to power off device)
Holding down volume down when you power up the device should boot into a recovery menu, if not,
Try holding Down [Volume Down] + [Power ] until The Phone vibrates (This may take a little while, keep holding)
If it vibrates but still doesn't work, hold down until you feel it vibrate twice. (this will factory reset the phone, so you'll lose everything)
One last thing you can try is hold down volume down, power on the device and connect the charger. Keep holding volume down until you see an exclamation mark. Then press the following combination of buttons:
Volume up, volume down, power, volume down. This will also factory reset the device.
(this point may void warranty if not careful)
If you feel brave, you could look into using ADB to connect and launch the recovery menu if all else fails, but it can get a bit technical, and my advice is that you should have some experience with adv or flashing or similar. Google and read guides for it and decide for yourself, but remember, its better to wait for a repair on warranty than trying to fix it yourself at the risk of voiding warranty. (also, you usually get 3months warranty on the repair.
Hope this helps

[Q] How to shut this thing off(one S villeC2)?

This might be the stupidest quetsion ever but, I'm totally helpless.
I need to access the recovery, I flashed a rom which stucks at the boot screen, I need to flash another yet I cannot shut this thing of. I keep pressing the power button for 10secs, 3buttons starts to flash and screen goes dark. When I let it go, it restarts.
How can I power of this device without accessing the OS?
