[Q] Cannot get download mode - HELP

I was trying to get 2.2 on my captivate. It got hung and after about an hour, I powered down phone (battery out).
I'm now getting [phone... (!).. COMPUTER] picture
Trying to get back to stock ROM 2.1, but I cannot get device in download mode
I had to use adb to get in download mode originally.
Is it possible I got a phone that doesn't go into download mode based on button combinations? If so, what do I do?

Unplug your phone from USB
Pull battery
Close Odin
Open Odin
Put in battery
Hold both volume buttons (NO POWER) and plug in USB
Hopefully this gets you into download mode

Still Fail
I've been trying that, but without open/close of Odin.
Still failed when I added that step.

get to that screen again: hold volume up/down and power at the same time.
When the screen goes black, then release power button but keep holding down volume up/down

Yes, and remember to keep the volume buttons pressed in while plugging in the USB... I always hold them in until the droid/caution sign comes up.

Try the methods prescribed. There are several minor variations but you may have a phone that doesn't do three button recovery. In order to tell, we need some history on your phone. What is the RF Cal date? Were you able to three button into download before? Do you know if it was one of the ones that had the three button problem?

autocorrelation,
I tried that with the usb cable plugged in and without it plugged in.
Still no good.
joeybear23,
I've been trying that all afternoon. Probably about 50 times.
ianwood,
How do I get the RF Cal date? I don't see it under the battery where the S/N is located. I tried to do 3 button recovery to put phone into download mode when trying to install 2.2, but it wouldn't work. I had to use "adb reboot download".
I've never tried it before today. The only issue I've had was that it could NEVER connect to AT&T server to check for an update.

can you get it into recovery mode?

no recovery
No. It won't go into recovery mode either.
The only thing it WILL do is respond to all 3 buttons being pressed by the black screen flash after about 8 seconds.

If you keep holding all 3 buttons will it flash again after the initial black screen? Try releasing the power button and keeping holding vol up/down after the second black screen.

If I keep holding all 3 buttons, it just keeps flashing.
Also tried to let it flash twice (and even more) and releasing power right when it goes to black 2nd (or 3rd) time. Also tried releasing power half way through black screen, and right before black screen re-appears and also just as the screen powers back up. None of them work.

I ran into this yesterday and about freaked out. Don't panic - apparently one of the guys had this happen to them a lot. Take a deep breath, have ODIN open, plug your USB cable in, hold the volume buttons down at the same time, press and hold the power button till you see the phone to computer, and let go. You should get to the download screen again. Good luck; sucks when something like that happens and you don't know what's going on.

I know this wont help much, but I have one of the no 3 button phones, and after 20 minutes of trying all these methods, it did go into d-load mode. Unfortunately, I don't know exactly which combo I used since my brain went into overload when I finally saw the triangle appear. There is hope though, and please PLEASE post which one works for you(I'm afraid to mess with mine until I find a foolproof method)

I had a phone that wouldnt respond to ANY 3 button combo I tried. I bricked it (sorta on purpose) to the phone-!-computer screen and went and replaced the phone at AT&T (under the 30 day deal).
It didnt initially work with the 3-button but after the JH7 OTA DL mode and recovery mode work perfectly now. Also, GPS has been completely spot on when testing on my motorcycle with the phone in my backpack running my tracks.
If you are under the 30-day return policy, bring it in and come up with a good reason as to why they should give you a new phone. If not, then you're sorta SOL....

This method just saved my butt!!!
I have never had trouble getting into recovery or download mode until today when I did a dumb thing. The phone would lock at the ATT screen when trying to power on and if the phone was off and I plugged it in to charge it would freeze and the circle logo that comes up before the green charging battery does.
Every method of getting into download or recovery failed up till now.
Thanks Zilch!!!

Hey guys gonna move this to Q&A.

I had this problem a few days ago after updating to 2.2. I tried every single button/usb/battery combo and nothing worked. FORTUNATELY I was within 30 days of purchasing it (I guess there's a silver lining when diving right into "hacking"), and I brought it to the store with the box and receipt and just told them it gave me an error when turning it on (played dumb) and they swapped it out without even testing. If you're over the 30 days then I think you're pretty much SOL... gotta pay for a replacement.

bricked
I declared it to be bricked and took it back to the store. I have only had it 2 weeks, so I basically pulled the same move of playing dumb and they gave me another one without any problem.
I'm wanting to try to see if I can put it in recovery mode and/or download mode with the buttons without even attaching it to anything, but now I'm paranoid about bricking it.

Buddy, we need you to remember I'm in the exact position, no combo works and I bricked it after trying to load 2.2

Going into recovery or download will not brick it, its only everything after that point that might get you bricked.

[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.

can not boot

One day I went to use my tablet after a long time not using it. It was on the stock OS. And it stops at the Asus screen with the spinning circle I know sometimes this might take awhile so I let it sit for 24 hours and it still is there. I tried cold boot and reset to default and also the recovery image. With the recovery image I get a dead droid with a red ! above him. When I plug it into my computer I hear my computer detect it but I can't access it.

Guessing the OS is corrupted. Bring it back to stock again using easyflasher. You will lose all data by doing this.

You need to be in apx mode to use easyflasher. Press power and volume up for a few seconds and connect to PC. Your tablet should be recognized however the screen will stay black. Then you can use easyflasher. Good luck! Also, try to never allow the battery to go completely flat. If you will not be using it for a while power off.

it is not letting me go into apx mode. When I try turning it off it restarts and goes to the boot screen and freezes there. Is the recovery image on the SD card? I can get to the recovery so I might just put the stock zip on it and try it.

I just tried updating it and I keep getting the same dead droid and it keeps rebooting when I try to power it off so I cant enter apx

Try holding POWER and VOL UP and it should enter APX even if it isn't off first.

No matter what I try and how many times I try when I push the power button it just restarts. if I hold the Power and Volume up it restarts and sticks at the Asus screen. In the Device Manager for a description for the tablet it says "This device cannot start. (Code 10)"

I had that error and it was a bad USB cable. My cable still worked with the stock charger, just not for USB (MTP/APX/ADB)

I do have 2 cables and last time I used then both did work so I know that is not a part of my problem.

You won't see anything in APX mode and may think the device is powered off. So connect it to your computer first, then try to go in APX. You should hear the computer detect the device.

Does it still reboot when you try entering APX mode if the USB cable is disconnected from the tablet ?

yes it reboots if it is hooked to the computer or all by itself. If I try to enter apx by itself or hooked to the computer it still reboots.

If I can't get into apx does that mean that I have a brick?

Possibly, or your power / volume buttons aren't working properly / getting stuck pressed in
Might be worth taking it apart and disconnecting the battery for a while / checking buttons are working without the plastic bezel over the top of them
Check no cables have come loose causing weird behaviour

I opened it up cleaned the buttons unplugged the battery and looked for loose cables. Plugged the battery back in and rechecked for loose cables. I tried going into APX and that is a no go. I have not reassembled the unit back together yet.

So what should I do next?

I got it fixed!
I unplugged the battery plugged it back in, did a cold boot then enter apx mode

HTC One S stuck on HTC One Beats Studio Screen

Hello Everyone. I recently got this HTC One S from a friend but it won't boot. If I want to boot it , I have to plug it in and press the power button even tho the battery is working. Sometimes before the phone even shows the HTC screen, the touch buttons blink then it boots into this screen. It's stuck like this forever. I tried accessing recovery/hboot through the power+volume buttons but it did not work. Any help to make it boot into android?

Hi, i hope i can help you.
Hold the Power and the Volume down button. When the Phone is starting and the touch buttons are blinking DO NOT let go the buttons until the screen turns black. Now let go the buttons and press them again immedeatly (up to 15 seconds) until the screen turns on again. Now you should be in fastboot/hboot.
If you need further help, I'm around.
Good luck

It doesn't work since the phone auto startsup for some reason even if I unplug the battery, and replug it.

So you tried the procedure with plugged and unplugged battery and non of the hardware buttons is responding?
If so, and the computer doesn't recognize the device in any way, you need someone smarter than me. I'm sorry.
My next tip would be to disassemble the device and check for hardware problems.
I hope you find a solution

Hi, One Plus that won't turn on, won't charge, won't get into recovery mode

Hi, I have a One Plus 8T that won't turn on, won't charge, won't get into recovery mode, the screen remains black, won't vibrate on changing ringing mode either and gets recognized as QUSB_BULK_CID:xxxx_SN:xxxxxxxx when connected to the laptop. Phone was in my hand and in a perfectly good condition when it happened. I tried all the physical keys and their combinations many times. Is there any solution to this?

You're in EDL mode. Hold power button and volume up button until it reboots. Then see where you are. However, you may need to use this tool to flash back to stock - https://forum.xda-developers.com/t/...l-to-restore-your-device-to-oxygenos.4180837/

one thing i want to add here is when phone is conected to a laptop and i press Vol Up + Power key, i hear a beep on laptop (may be it does the reboot) but screen remains black. I dont think the issue is with the disoplay.

Then you will need to use the msm tool. Your phone seems to boot into EDL mode just fine. Follow the instructions in that link.
