adb for the reason it doesn't reconices the device. help!!!!!!
Plug your phone into you computer via usb while its off, wait for the battery charging icon to appear. HOLD PWR+VOL-UP+VOL-DOWN until the screen goes black, then RELEASE POWER, but continue to HOLD both VOL buttons. That should boot you into download mode NP

Sorry to those members who may get angry by me posting on the dev section i thought i was on the general section. but that did not help thank you!!! very much for posting.
make sure you have the Samsung drivers installed for your phone, you can find both 32bit and 64 bit drivers floating around
boot your phone into stock recovery
now plug your phone into your computer
go to adb, type adb reboot download
its called google search
same issue
I have been reading through xda and other sites as well and it seems like the replacement vibrants cannot get into download or recovery mode manually. I'm stuck on the phone+!+PC symbol on my phone. It's been a day now and I cannot for the life of me get this thing in download mode. Literally have tried every possible way. The funny thing is that my original vibrant could get into download mode very easily. There have been suggestions that the volume keys are disabled for getting into download mode on the replacement phones. Any ideas or suggestions besides returning the phone or waiting for another replacement?
I'm on my second Vibrant too. First one wouldn't boot into DL mode at all and I killed it when installing one of the lagfixes. Nothing worked; button combos, adb, no matter what I did I couldn't access DL mode or recovery. Fortunately I was able to get another one from T-Mobile. My suggestion would be to make sure you can boot into one of those BEFORE tinkering with anything on the phone. Chances are that if you can get back to recovery you'll be ok. If you can't get there on a stock phone then take it back to the store and tell them you're having random reboots or shutdowns. The store rep will most likely try to do a master reset. If it won't boot into recovery for them they should give you a new one. Good luck!

Okay, so I think I brainfarted and softbricked my Vibrant. I tried to get it into download mode, but pressing vol up+down only gets me a gray battery icon, not the usual download screen. When I power it up regularly, it goes into bootloop. It's never had a problem going into download mode before, so I don't know if there's a malfunction with the vol buttons or what. I certainly seem to suck.
(Ugh, just noticed the no questions in the general forum rule. Mods, please delete)
Pull battery
Plug phone into computer via usb
Hold vol up, vol down, and power
Replace battery while still holding those buttons
U can go to 4shared and grab a app called hot boot, it will put u in recovery

Turn off phone
pull out battery
hold Volume UP and Volume Down
Plug in USB cable to computer
Put battery in
Once in download mode let go of Volume UP and Down
You could always us the toolbox

try to do the same steps but hold the vol up button only (not the down)!
this the only way that i can get into download mode!
These guys listed about every way to get in to download mode. If none of them work, you are doing something wrong...
Are you running gingerbread or froyo?
Button sequences are different. Gingerbread uses one volume button(depending on the kernel either up or down) and the power button, while froyo uses the both volume buttons only.

(Depending on the level of softbricking you will either see the Android with a shovel or a phone and computer with exclamation mark, both are download modes)
Froyo bootloader:
Pull Battery,
Put Battery back in phone,
Hold only volume up and down at same time.
Insert USB.
GB Bootloader:
Pull Battery,
Put Battery back in,
Press and hold Volume Up+Power button.
These should work without flaw. If neither work for you, you may need to invest a couple bucks in getting a USB Jig.
Same issue witht similar results
I am having the same issue, Phone was rooted, on the Keis Gingerbread Update. When I tried to restore to Froyo, using T959UVJFD it got stuck in a boot loop, Tried to go to CWM cyogenmod using both Oden and Recovery and Odin Failed, Recovery gave me the evil Signature Failed.
So I tried a different Froyo EUGENE373 which bricked the phone. I was able to unbrick with onclickUnbrick (Awesome app, thank You). But when I tried to apply The Factory Froyo again it failed in Odin.
Now, the PC will not recognize the phone, USB divice failed message. I removed and reinstalled the drivers, Tried the Samsung Drivers, the Keis drivers and Hiendall drivers as well as the USB drivers with the ADK / SDK toolkit. I tried to connect the phone to another PC with the same result. I know that I am doing the process to get into Download mode properly, but it only displays the greyed out battery, with the USB unplugged the phoned boots to the Galasy S GT-I9000 Samsung screen and I am not able to get out of it with any button combo.
This is my wifes phone and I am in the doghouse for this one. I have rooted and flashed my Verizon Fascinate with no issues. Thank You for your help. if I can get into download mode I was going to follow the process in the NOOB root, flash sticky thread, unless someone has a better Idea.
Okay so I seem to have run into a little problem I was planning on updating cleanrom up to 1.2.5 but was on cwm. I had managed to switch over successfully to twrp 2.2.0. I went ahead and used goo manager to download the updated zip of 2.2.1 and tried flashing it thru twrp. Now I am stuck in google bootloop and cant get into recovery or more importantly bootloader. I have been trying last 30mins to hold power and both volume buttons but it either keeps rebooting back to the google screen or not doing anything at all just have to repress to to turn it off but it will turn back on automatically. I tried hooking it up to my usb and labtop but it looks like it wont even recognize it. I just fully charged it so I am good for now just a little worried cant get out of this mess.
I ran into a problem like that with clockwork recovery it kept on rebooting in recovery but I could still go into download mode I was at work away from my computer so I had no choice but to keep trying that three button magic until it finally restored a backup I had on my external card.just keep on trying to pull the battery then try to go into recovery. You might 've gotten a bad download

problem is I cant get into recovery. or the green screen to get to bootloader. It just completely stuck in a bootloop on the google screen mocking me... I am really contemplating opening it up and taking out battery but is that a good idea? Or is there anything else I can do?
so I pulled off the back cover but really dont want o disconnect the battery might mess something up but I cannot get the device to shut off.
disconnecting the battery does nothing it shuts it off and keeps it off but when I connect it to the charger the battery symbol pops up for a second and then goes completely blank. I went ahead and tried again to boot into bootloader pressing power vol up + down and all combinations of power vol -, power vol +
power turbo press vol +/- but no luck still in google screen.
If you're in a bootloop you need to connect your Nexus 7 to a computer. Then you will be able to access recovery via the Power button and volume buttons.
is it going to make a difference that everytime i try to reboot it just the black google screen? I have tried it connected to the wall charger and connected usb to the labtop but nothing.

It's supposed to do that when you're trying to go to recovery from bootloader without the USB cable plugged into a computer, may need to have the drivers installed on said computer. It's an issue with the nexus 7 bootloader and every one of them does it. What your experiencing is perfectly normal if you tried to go to recovery from bootloader with the bolume buttons and then got the google screen bootloop.
If it doesn't work when you plug it in and try, then try unplugging it, manually rebooting with it plugged in first, or vice versa
Update: I can get on Team Viewer and remotely reboot you into recovery through the PC if you want, or at least give it my best shot.
ok so i disconnected battery and have the device off. I should then try connecting it to the pc and try booting up holding down all buttons?

Have you installed the right drivers on the computer you're using, for ADB and the device drivers, when you unlocked and rooted?
Answer to your question is yes try that. But I wouldn't be disconnecting and reconnecting it, I can't recommend that and then learn tomorrow that static zapped something important.
yea I am getting nothing by connecting to pc. I have all the drivers adb and fastboot installed when I rooted and unlocked couple weeks back but it looks like device is not being recognized or read at all by the pc.
connecting to the pc holding the volume + button gets it recognized for a second and tries to install a driver apx but unsuccessfully.
I am not making any progress whatsoever kinda sucks starting the weekend like this. I have gone thru some bad stuff with my atrix but nothing like this were I cant even access my bootloader boot into recovery or even fastboot. Should I try and get it to just stay off and see if overnight it works its own magic? Hate going to sleep witht his on my mind but I think with a clear mind in the morning something good will happen.
I can get it to stay off by holding both vol+ and vol- but trying to turn it off with just the power button just keeps it turning back on/off...
so I slepted on it thru the night let the tablet rest but went back this morning and I still cant get into bootloader or recovery. Is there anything I can do?
Has anyone else had this problem where they cant boot into recovery or bootloader? It's like the power button and vol keys are unresponsive even though they still work to turn on the device.
are you sure that you flashed the right recovery? but you should still be able to get the bootloader. are you pressing power + volume down(volume down, not both volume buttons. i noticed you wrote both volume buttons) to get into the bootloader?
I think I chose the right recovery the first version downloaded thru goo manager but it was the 2.2.0 version. I had the option on the of downloading the 2.2.1 zip or the .img but i downloaded the .img to just to flash with the current version of twrp that was working. There have been times were I have not been able to get into recovery on my atrix or htc but I've always been able to get into the bootloader this is the first time I've been locked out of my device kind of got me scared its not even a month old. So you say to get into bootloader you dont have to hold down both volume buttons? I will try again to power back up using the volume down and power button at same time... Wish me luck

yea, only power button and the volume down button.
quick question before I connect the battery does it make a difference whether or not I have it plugged in charging or connected to the PC while trying to boot into bootloader?
such friends have a big problem with my G2 I want meti up the volume on the stock rom kit kat and so we change the audio xml file I saw in a tutorial here in HTCMania, but restarting the phone will stay locked in bootloop where it says tmobile.
then proceeded to do hard reset thinking that would be solved well but after performing hard reset STAYING was still locked.
well I'll have to reinstall the software and told me when I headed to want to put the phone in download mode (off the phone and press Vol + connect usb cable) to my surprise the phone did not enter the download mode. the only thing it does is connect the cable to charge on and get off.
and since then I can not find a way to revive him because I can not install the software, and "NO I HAVE INSTALLED A CUSTOM RECOVERY" so do not'm desperate someone could throw me a light? if somehow you could do enter download mode on the phone in an alternative way?
my device is a rooted

First i would try getting in to recovery using the hardware keys. Look it up on you tube. Then you should be able to use a back up if you made one.
To get in download mode you need to power off then while powering on hold the vol down key and plug in the usb cable. That will get you in download mode. You shouldn't have to do that though if you have a back up. Your phone isnt bricked?

sorry friend, but is that as explained in the previous post: long press volume + but does not go into download mode, this as locked or not happens.: Llanto:
Jesus Christ.
Press and hold power and volume down until the display shuts off and the LG logo appears. Then, try pressing and holding volume up and volume down until a hard reset option appears. Reset the device and try booting it up. You will lose all data on it, but that's what you get if you're not smart enough to back it all up.

A hard reset will not help if he made changes to the system partition (which it sound like he did). If he has a recovery installed (kind of a weird sentence in the OP) this would take him into the custom recovery though.
@tuberodx7 If all else fails I'm convinced you can get it into download mode if you do it right, something like that should definitely not kill that. From there you can flash a factory image (Search for the return to stock thread in the General forum)... Your device is far from hardbricked, please do your research...
THis is general thread. Post it at Q/A.

Ok, if you're absolutely definitely positively sure you're doing it right and it still doesn't work, you might have to manually reflash some of the partitions... Refer to this thread (and be careful) http://forum.xda-developers.com/showthread.php?t=2582142

Hi,
I have a new a20e (a202f) out of the box.
I followed another guide to root and install twrp which turns out was wrong. I unlocked the bootloader just fine.
I have no backup, no personal boot.img or anything.
Essentially I am stuck in download mode and restarting takes me straight back to download mode.

What guide did you follow? You have to download your stock fw from sites like sammobile then from there you can have the boot.img and etc. Have you tried flashing stock fw using odin?
Note: Usually you flash vbmeta for footer error when you flash twrp.

It was a guide on 'unofficialtwrp.com' - I can't link things here yet.
I have since tar'ed an unpatched twrp (TWRP-3.3.1.0_A20_by_Agrim720.img) + vbmeta.img + boot.img (from https://forum.xda-developers.com/galaxy-a20/help/boo-img-a205fxxu2asfb-t4008739), then I flashed through AP on Odin and now I think it boots past the download mode but instead it now has fuzzy dark red screen with nothing legible.
Oh bugger, I've been a class A plum.
Can I get out of this horrible mess?

Well you have to use your own boot.img from your fw, not all of use the same fw that's why, some are still on u2, u3 and u4. Maybe the boot.img you got isnt the same as your fw.
Well you can start from scratch and reflash your stock fw in odin.

Try holding volume - and power and your phone will turn off, as soon as it turns off press volume + & - and plug your usb cable that is connected to a computer.
No luck with that. It displays the message about running custom os etc and to press power to continue. So I press it and it boots to the messed up red/pink/black display.

Do you mean like the one attached? If yes you havent booted to download mode.
Try booting to recovery by holding volume + and power while you turn on the phone.
There is a option there to boot to download mode.

Yes that screen. I've tried your suggestion with volume + but that also ends up with messed up screen
Yes so currently I'm unable to get to recovery (not sure it even flashed properly), unable to get to download mode, or to get the device recognised in odin.
I'm unable to power off. The screen is blank and when I press power it flickers shortly with some black/white/red pink colours around the edges, but the screen quickly turns blank.
From this position I can only restart by holding volume - and power.
This boots to the samsung logo and then the 'bootloader unlocked' warning. No amount of button configs have proved successful so far, and then I end up back at the blank screen.
I'm happy to start from scratch. I have downloaded the stock firmware but I'm simply unable to proceed.
Aslo the device is not recognised in windows at any point.
Thanks guys

Are you sure you pressed and hold volume +&- and plugging cable before the samsung logo pops up? You have to do it quickly right after the device turns off. You shoudn't see the bootloader warning if you done this quickly and correctly.

Hello -
Please trust me when I tell you that it can be fixed. I had the EXACT same problem and drove me crazy for 24 hours. You can deffinetly fix your phone once you get to download mode.
I had the same issue where I could not turn the phone OFF it just looped back and I pushed buttons for hours to no avail... Then some one told me it WILL WORK, it is just the timing of
the button pushing, AND the USB cable plug in. Sure enough he was right. It took me alot of tries and I even took my phone apart and un plugged the battery so I could controll the power
ON / OFF better and time the button's easier. Here is what I did ...
unplug battery so phone was 100% OFF.
Plug in battery ( phone is still OFF )
Hold Vol - then Hold Power and Vol -
As soon as the power started IMEDITALY PLUG IN USB ( have USB READY to be plugged in FAST )
DONT let go of buttons ... screen will flash quickly and then Imediatly let go of power keep holding Vol -
IF you timed this right, IT WILL proced to download mode. If not, then start over again from power OFF ( step 01 )
It took me 3 tries to get it ( after 50+ tries before ) lol
Now I am not sure about the battery unplugging ... maybe you dont need to, but it mad it work for me as I could control the power ON part of this now.
Getting to your battery is not very hard and there is a you tube video on how to do it... if you need help just PM ME.
Good luck friend.
When this happened to me all I did was hold volume up and volume down. Kept cord connected to computer. Connected to device during the bootloop and boom within seconds I was in download mode. It catches it once screen goes off in between the bootloop.
Sent from my SM-N950U using Tapatalk
Thanks you guys. In the end the battery died and then I could power up whilst holding vol+, straight to recovery and then I could flash stock rom.
Much appreciation for your help guys, it got me out of a pinch - it is my mother-in-law's new phone!
