The thing is i flash vibrant7 flash OK but it was freezing so i made a nandroid of stock rooted vibrant so i can flash back to. So on the proses of nanrestoring it finish and rebooted but it got stock on the vibrant screen not booting up. so i tried going into download mode but no good tried every single button combination no good. so am asking how would you know if you have one of those vibrant that cant boot to download mode. also i cant access
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!

Can't get into download mode

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
http://forum.xda-developers.com/showthread.php?t=954509

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.

[Q] Nexus 7 in APX mode?!?!?

This morning I came down to find my Nexus 7 dead... No response from screen, and I was unable to get it into recovery mode.. I have recently unrooted and relocked the device, flashing it with the JRN84D factory image from the google website and then upgrading to the latest firmware OTA.
I thought the battery may be dead, but it's been on charge for two hours and I am still unable to boot. I decided to plug it in, and lo and behold, I get a response! By virtue of Naked Drivers, my computer now recognises a seemingly dead device as an Asus Transformer Prime in APX mode... No ADB or fastboot response...
What can I do from here? I am reluctant to return it because I am leaving for vacation soon and won't be in the country to accept the order..
Any help would be appreciated..
BTW this is my first android device I have rooted, to I'm fairly new to this..

I think that it's just frozen. You need to simulate pulling the battery out, try a long hold on the power button and see does that fix it for you.

Mine is in APX mode too. I was using it last night, rebooted it, and nothing. Screen is dead. It is a 16gb model from Staples and all of them are out of stock to replace it.
Any solution?
APX mode is used for NVFlash. I'm tinkering with NVFlash trying to somehow push stock software or something but I keep getting unknown device error. The device doesn't do anything at all. But if I hold Volume Up and while on a PC, it will ding and install the APX driver... but at this point I am completely lost.
This happened with my LG G2x once and I found a script that repartitioned, reformatted, and flashed over a stock image. I haven't seen any mention of NVFlash with the N7 though.

Unplug it from your computer and press and hold the power button for 10-20 seconds. Then release it and try to turn the tablet back on. It may or may not work. If not plug it into your computer and see if it went back to apx mode. If so, unplug from the computer again and try holding the power button until it turns off again and try booting into the bootloader by pressing volume up, volume down and power all at the same time. If you can get to bootloader, you can either flash back to stock using fastboot or try getting into recovery. If none of this works, call Google and tell them what happened and what it does when you plug it in to your computer and maybe they'll know how to fix it or will replace it.

Yea this is not the same case here. I've bootlooped my N7 before and your method would typically work.
But not this time. The screen doesn't even come on. There is no indication the tablet is on or off except the little ding on the PC when it comes up as APX mode.
So ADB and Fastboot commands are not an option. I already tried that. NVFlash is the only thing close to talking to the tablet and its saying unknown device.
I bought this at staples so I guess my only option is to return it. They don't have 16gb models and it doesn't look like they are getting any for weeks.
I can pick up a 8gb model but I don't want to be stuck with that.

I've tried everything...
I've tried everything, but short of NVflash - which I am reluctant to attempt - nothing works.. Seeing as at the time my device decided to go into APX mode my bootloader was locked and I was running stock ROM, I had no choice but to return it to Google, which is surprisingly difficult to do if you live in the UK...
For some reason Google decided to switch to TNT for us brits, and the customer support agent on the phone was particularly clueless as to how you go about returning an item if you are at the disadvantage of not actually living in the states... After many phone calls and much persuasion, I managed to prise out instructions on how to return an item if living in the UK...
However, a piece of information for anyone in the UK who wants to return an item: TNT do not deal with punters directly; they purely deal with businesses, the consequence of that being you as a customer CANNOT book a collection yourself. Instead you must ask Google to arrange it for you, which they will certainly not be able to, seeing as many of their frontline support agents seem not to have been briefed on this...
I ended up having to use Royal Mail...
Just a bit of info for anyone in the same predicament as me..

Did anyone figure out how to get out of APX mode?
My Nexus 7 was intermittently rebooting/freezing so I ran a 'StabilityTest' (CPU + GPU). Within one minute of the stress test the tablet rebooted and went straight into a blank screen. No matter what buttons, the tablet just won't boot. I plugged in the tablet to the computer, and I get the APX driver not found.
I'm past my 15 days to return the tablet to Google, and besides my tablet bootloader is unlocked. Though I never flashed any ROMS/kernels. Does anyone have any recommendations on how to proceed?
Thanks

I don't know the exact steps, but i got it out of the APX mode and into the bootloader.
1. Tablet plugged into computer.
2. Held Volume Down + Volume Up + Power (simultatenously) for three seconds
3. And then released all, and pressed Power again.
4. Tablet booted into bootloader.
I thought that unlocking the bootloader ALWAYS voided the warranty, but in anycase I flashed reflashed ALL stock and locked the bootloader. Will be sending it to ASUS now. Thanks again!
EDIT:
So I wanted to verify that it was a CPU problem, and I downloaded StabilityTest again and ran the CPU load test. It crashed within two minutes, and went into AXP mode again. To get it out of AXP mode, the correct instructions:
1. Plug in the usb into computer
2. Hold Volume Down + Volume Up + Power simultaneously for like 15 seconds
3. The bootloader should show up.
4. If it doesn't, unplug the usb cable, and plug it back in and then repeat the these procedures.

Mine went back to staples. I could never even get the thing to come back on. Perhaps it blew up.
Had my Google Play model now but this one has some screen lifting going on. Nothing major

I randomly kept pressing the volume / power button for an hour and the tablet came out of APX mode. Make sure the tablet is in APEX mode by plugging it in to the computer--the APX device drivers should install

You sir, are a savior! I was on vacation in when I woke up to a black screen on my Nexus 7 and nothing I tried work to get it booted. I tried this on a last hope that it would boot and it completely worked. So glad I won't have to deal with talking to Asus or Google to try and get it repaired.

MAN! You saved me! I'm hard rebooted to stop a CWM backup and got this problem. THANKS!!!

I had the same problem, and SimFox3's advice got me out of APX mode and booted. This appears in my case to be due to some kind of 'deep discharge' problem, where I let the device run down completely, to the point where it would not charge and was completely unresponsive.
After following SimFox3's "3 finger salute" trick, I got into boot, but then the device immediately shut down with 'connect charger' message before I could boot completely. After this I swapped back to the mains charger, and am now getting the charging animation, so fingers cross It will boot up fully after a couple of hours charging.
There seems to be loads of threads about the Nexus 7 and battery "deep discharge" type problems. Anyone seen any official information about this?

I interrupted a sideloading flash (didn't think it started anyway) and am getting this problem.
Tried Sim3fox's solution and still not working.
Any suggestions? It seems like fixes are happening at random.

Thanks

[Q] my tmobile g2 is hardbriked :( help me

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:

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.

So. I messed up in TWRP pretty badly.

I originally posted this in general and then saw the sticky saying your not supposed to post questions there. Sorry for the double post.
I'm selling my G2 on ebay. It sold. I rebooted to TWRP and did a wipe on everything, including the internal storage, so I could follow WALTCOs guide to uproot and flash stock. Now when it reboots, all that comes up is the LG flash, but no bootloader, nothing. I can only assume that I wiped the rom, recovery, and EVER THING off the phone.
I'm a little terrified. Did I brick it? Is there anything I can do at this point?

Can you get into download mode?

I had a similar problem a couple of days ago - but while the phone was connected to the laptop I noticed that by holding the power and volume up button I could get the phone into the download mode -(the LG logo appears but keep holding the buttons down and hopefully download mode will appear) I then followed the instructions in the below thread and return it to stock - lost root but still has TWRP.
http://forum.xda-developers.com/showthread.php?t=2432476

Hmm...holding power and volume up, it says download mode started and flashes to a dog window saying fast boot started. Is this download mode? When I connect it to my computer, lg flash tool can't read the phone info, mentions the port. I checked in device manager and it's listed as an ADB device but I can't see orly change the port.

If you're in fastboot then download mode failed to load.
fastboot is an interface which is somewhat similar to adb.
You can try flashing working images to your phone through it to fix download mode.
It's pretty easy to brick your phone like that though so be careful.

any luck getting it to work? i don't hold down the power button on my phone to do this. turn the phone all the way off. hold down the power until after the the brief flash off the splash screen logo. that way, it is all the way off and not rebooting. now, hold down the volume up button only, then plug in the usb cable. that should do it.
