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.

[Q] [Q} Broken Power Button, Phone won't go into Recovery or Download Mode

The power button on my phone recently has stopped working. I need to get it warrantied, but I am running CM 10.2. I need to Odin back to stock, but I can not get into Download Mode or the recovery. When I go into Download mode, the initial screen pops up, the one where you choose to hit up to continue, or down to reboot normally. After I hit up, the screen goes black and nothing happens.
I really need to get back to stock, as Bestbuy are being dicks, and demanding I do a factory reset before they send my phone in.

Anything? I still need help on this.

This has been covered at least 10 times in the past few months we need a sticky. Take your battery out hold your phone so the power button is facing a table or floor and slam that side a few times it should work again (Temporary). You might need to hit it on the surface really hard 10-20 times before it works. Just not to hard or else you might crack the screen. I used a mouse pad to soften the impact. This trick no longer works for me so I ripped the button off. After about a month of doing this I needed to use things that would only hit the button to make it work. About a month after that nothing worked so I just took it off the motherboard and now boot from a off state by plugging into the wall and enter odin mode deny the prompt and it kicks me into a workable state.

I can get into the system just fine. When I go into the recovery or download mode, it doesn't stay in that mode. I tried the banging thing, and it made my power button go from intermittently working, to not working at all.

keep doing it until it works. The button is sticking that is why it reboots/stopped working.

It sounds like your power button is physically broken, and it is activating intermittently, which is stopping the phone from entering download mode. My only experience with this problem is my own phone but ultimately mine got so bad that I had to rip the button off the motherboard, as ThePagel did. Your symptoms sound the same as mine.
You can try this procedure to get into recovery, which works for me without a power button. You will probably have the same problem you are having now with the phone rebooting on its own before you actually get into recovery, because the power button is activating.
1. Take the battery out of the phone and unplug it from USB power.
2. Plug in USB power.
3. While holding down the volume-down button and the Home button, insert the battery (this is a little tricky).
4. The phone should start and warn you that you are entering Download mode. If you want to use Odin to return to stock, do that now.
5. If you want to get into Recovery instead, press Volume Down to reboot and then *immediately* push and hold Volume Up and Home simultaneously. The phone should reboot into recovery. Mine does.
If that doesn't work, and you can't get a new phone without returning it to stock, then prying the power button off the phone's motherboard may be your only solution.

[Q] Constant vibration

Hi everybody!
I checked through all threads here about my problem, but could not find a solution.
One day ago the battery of my tab ASUS TF700 fully drained.
So I connected the tab to the charger and in some time tried to turn on it.
Nothing happened, it just started vibrating constantly.
The only method helped me stop vibration is hard reboot (power + volume).
When I hold only power button it stops vibrating for a second, make short vibration, again pause and then starts vibrating.
Connection to the monitor by HDMI didn't show anything.
I didn't do any updates right before this accident.
No root, no unlocks etc.
Please help me, I am desperately frustrated.
PS. there are some old trends with the similar problems, but without solutions.

Can you boot into the bootloader?
Push and hold Volume Down (left side of the rocker) and Power. The tab should vibrate twice, let go when you see tiny script and three icons.
Push Volume Up with the RCK icon flashing. If you get an Android falling over with an exclamamtion mark, you're good: your stock recovery is working.
You probably corrupted your system when you let the tablet crash in the middle of something. If the stock recovery is still working you can re-flash the firmware. Let me know if you can get there and I'll tell you how.

Hi,berndblb!
Thanks for advise.
Unfortunately my asus doesn't stop vibrating when I push and hold Volume Down (left side of the rocker) and Power.
So there are two options:
1. If I push and hold Volume Down (left side of the rocker) and Power,
then it stops vibrating for a while, makes one short vibration and continues vibrating constantly without any interruptions.
2. If I push and hold Volume Up (right side of the rocker) and Power,
then it stops vibrating for a while, makes one short vibration and finanlly stops vibrating. One trick: I have to push and hold till the moment when the device makes one short vibration, and only after the moment when vibration stops finally I can release the buttons.
That is all I managed to discover pushing and holding buttons.

Sorry friend, I think your tablet is hosed....
Pushing Power and Volume Up (right side of the rocker) should get you into APX mode, which is usually the last thing working if everything else is messed up.
But even if you get to APX - it's useless unless your tablelt is unlocked and you previously created your device specific nvflash blobs.
I'm afraid a new main board is your only option....

I have finally won
The solution was simple:
1. I let the tablet vibrating till the battery totally discharged (it took the whole night).
2. Vibration of course stopped.
3. I charged the battery a little and switched on the tablet.
4. Tablet launched in normal regime, all data and system were saved, even after I tried to make a hard reset (I suspect it didn't work out).
After that it only once rebooted without any reason, but that's all.
So several days passed, the tablet works without any problems.

It is good to hear that you have your tf700 back....:good: Thanks for the report back...
BTW, are you going to unlock your device and generate the Nvflash blobs? If it occurred once, It could come back again and hope for lucks again...:laugh: Just my two cents..

My phone does not turn on anymore

Yesterday I was watching a youTube video and my phone started restarting (crash?). The Google logo and ofcourse the unlock are showing (the device has been rooted a long time now), but it did not go beyond that. I then decided to hold the power button for a long time to manually restart the phone again myself, but after trying to restart my phone is not turning on anymore.
I already tried the standard things like holding the power button for a long time and in combination the with volume up and down buttons. When I plug in my phone it does make a sound like the device is connected to the laptop (most likely the adb drivers and ****.
Is there anything else I can try to get my phone up and running again? Also when in laptop or by adapter the phone does not show any sign of charging. (my phone was 75% full when the phone crashed).

Try holding Power and Vol down only during 10s.
If it doesn't work plug the phone to a charger and try again later.

I have tried that multiple times.

Do you have an early model by any chance? Launch maybe?
I bought mine at launch and it had a faulty power button. This also looks like a random reboot, because the power button is being "held" for a couple of seconds. I also hat a couple of times when I couldnt't turn on the device anymore - again, because the power button wasn't working correctly.

There is a possibillity. The nexus had problems with the power button a year ago. So I now RMA'd it,
