Bricked phone, can I get it replaced?

I was reflashing my phone, while in download mode, the power went off, and now my phone won't turn on or anything. I think my phone is bricked.
I bought the phone a week and a half ago. Will AT&T accept my phone for a replacement if I say it just stopped working? I have the $4.99/month Wireless Insurance, but won't they deny it when they find out I've been messing with it? What should I do?
Thanks!

Before you take it back, make sure it isn't bricked. Remove the battery, replace it, hold both the volume buttons, plug in the usb and see if it takes you to download mode

It's bricked. Replaced battery, won't turn on no matter what I do to it.
There's a small scratch on the screen, and the micro USB charging port cover is messed up a bit from something sticky getting in there.
What should I tell AT&T? What's the likeliness of them declining my claim? Can they tell that it's been tampered with even though it's bricked?

Wrong forum. But I would use my insurance instead and tell them it just quit on me...

Try plugging into the computer, remove the battery reinsert the battery. Then hold volume up and power till red text comes on the screen from there switch to holding both volume buttons down and power then when the red text flashes to black release power and continue to hold both volume buttons. That should get you back to the downloading digger bot.

They won't give you a hard time on the software side - to them off is off - they can't tell if you bricked it - they will send it somewhere and have it flashed.
BUT - if there is something sticky in the USB port then they do have grounds to deny your claim - for all they know you poured juice in there.
Good luck.

Get it into download mode and flash it again with odin. Likely not bricked.

I tried everything suggested, nothing happens. The power went out, while flashing new firmware, now the phone won't turn on no matter what I do. I already tried peoples suggestions.

The AT&T screen doesn't come up?

Guys we have been told a gazillion times about this...what does this have to do with Development?! Jesus....

Which firmware were you using at the time and which one were you flashing?

also make sure the battery is charged

Nothing does, I tried every combo, SIM card in and out, replacing battery, USB plugged in and out, download mode, regular power button, recovery mode, what the guy suggested above; everything.
Not a single thing shows up on the screen.

You glanced over my question.
The version of firmware you were using before the flash and during the failed flash can be very pertinent to the key combination you need to get into download mode =P

I had the stock firmware, installed the JM5 firmware, reinstalled the JM5 firmware, while doing so, they power went off.
Just pressing Volume Down + Power got me into Download Mode everytime.
Edit: And yes, the battery was charged, it was at about 67% when I was flashing the firmware. How can I charge the battery for the heck of it when the phone is dead? Normally when you plug in the USB cable there's a charging animation on the screen. Nothing comes up at all, can a dead phone charge a battery, or does the software need to send the power to the battery?

Honestly I've had flashes fail at varying points during the flash and I've gotten the black screen before, ALWAYS I've been able to get it to work by following these steps:
Pull out everything, SIM, SD, Battery, USB, EVERYTHING
Close Odin (If it's open)
Reopen Odin
Insert battery, hold vol down (If this doesn't work hold both volume buttons NO POWER)
While holding the button(s) plug in USB
Don't touch the power at any point, if this fails and you want to try the other key combo, start the process over completely.

This man speaks the truth, listen to him.

If your insurance covers damage then destroy the phone and call att and tell them its been destroyed.
if not then it is possible that the power outage could have caused your phone to zap.

Flashing or not if you spilled stuff into the usb port your screwed. Week and a half and you scratched the screen and did that? I have tried to scratch mine with no succes. I say ditch that phone and get a GO phone. And have a mod delete this pointless thread already!!!!

[Q]HOW TO RECOVER A HARD Bricked Sony XZC6002?

This is a HARD Bricked phone that first started going berserk after a partial install of a SONY software update. The phone would flash the home screen and continually vibrate. I forced it down with power off. Did not know what I was doing and believe I converted a soft brick to a hard brick. The soft brick at first responded to power button and volume up button to reboot. After that point it became more and more unresponsive to complete death.
It is not recognized by PC (even in the device manager) when plugged into USB port on PC. NO LED or any lights on the phone at all! No red charging LED with charger plugged in, No Sony screen icon, no vibration with power button pushed hard for >10 seconds (with and without pushing up/down volume). The ONLY response I get is an audible windows sound coming from my PC as long as I hold the power and volume up button down.
I have left the phone off a charger for >48 hours and then placed it on the charger for 6-7 hours. Still no red LED while on the phone was on the charger. Reason for me doing this was my reading notes that Sony had a battery error issue that could only be solved by removing the battery or draining it completely. Recharging the battery was suppose to be a fix. A recent poster did this (removed the battery) which is a job and was able to get a red LED but nothing else. There was no reply.
My readings also indicated that there are a number of people with this problem (hard bricked phone) involved with download or install of their software Sony reportedly has a fix to install to correct it. I am a day late and a dollar short.
BTW, the Sony PC companion works up until I connect the phone to the PC and then an error message appears to make sure battery is charged to 80% before proceeding. Ignoring that brings up a troubleshooting screen prompting holding the power button and volume up button for 10 seconds. This is where I get an audible windows connect/disconnect sound coming from my PC that will keep sounding as long ass I hold the buttons down and stops after I remove them. Could this possibly be just a battery issue? Any help is greatly appreciated.

Firstly, you've made one major mistake when you've turned off your phone by using force. It can completely brick your phone forever.
Secondly, if you can hear any sound when connect your phone to USB, then thats mean, that your phone is still in minimal functionality. However, you can give a try to buy a new battery and see, how it goes.
It's better to buy extra battery, than change the whole phone, am I right?
And try to leave your phone without touching it for couple days I think. Maybe your battery somehow has got any fault or it has been faulted when you've force-shutted the phone.
Just give a try and that's all. You can't do anything else, except if you know and you're ready for phone disassembly. If none of my suggested methods will work, then try some other tutorials, you can search for them in XZ category's. I've forgotten how that thread is named, but you can search by some key-words, like : ultimate recovery, back to life, unbrick and etc.,
I hope my information is all correct and helpful, if not, then sorry for disturbation for nothing

My gut tells me that the battery is OK but needs to be recharged. Apparently there is something that will not allow the battery to recharge unless it is removed or drained to zero. I thought I drained it to zero but perhaps not. The other case where the battery was removed and was then able to show a red LED apparently allowed the battery to recycle. That's as far as he got.
In the mean time I'm taking your advise and just letting the phone sit until someone makes a suggestion or I get tired of looking at it.
Thank you for your time and suggestions.

Can you enter the "fastboot" mode (unlocked bootloader) /"flash mode" (locked bootloader) ?
Hold "volume down" button and connect with USB cable to the pc.
So first hold "volume down" button and then connect with USB cable to the pc while holding the "volume down" button. Let go the "volume down" when a green led on your phone appears.
You can still enter the "flash mode" if the green led appears.
Hold "volume up" button and connect with USB cable to the pc.
So first hold "volume up" button and then connect with USB cable to the pc while holding the "volume up" button. Let go the "volume up" when a blue led on your phone appears.
If the blue led appears on your phone you can still enter the "fastboot mode".
There is still hope if the green/blue leds appear on your phone (meaning you can still enter "flash mode" / "fastboot mode".
. But the following question need to be answered:
Has your phone an unlocked bootloader?

It is HARD Bricked. Unresponsive to all of the above w/o any LED response.
Has your phone an unlocked bootloader?
The phone was purchased from Sony and was factory unlocked. It was running fine until the new update from Sony was installed. I believe the update was related to the OS which is 4.4.4.

N6 power button stopped working, now I can't turn phone on

My power button stopped working a couple days ago but I was still able to wake device with volume buttons. I was worried that if my phone were to shut off I wouldn't be able to turn it back on so I booted into bootloader and was going to try and flash "oem off-mode-charge 0" (which should then make the phone power on when plugged into charger).
At the time I couldn't detect the device using fastboot and as I was searching around on my computer the screen on the phone turned off (was in bootloader at the time). I'm not sure at this point if my phone was on and that both the power and volume buttons were not waking device or if the phone turned itself off.
I have tried the hold the volume down and plug the charger in trick to try and get back into bootloader but nothing happens. When I plug phone into my computer it takes about 20 seconds but I get the little windows ding that something has been connected but phone is still not responsive. I'm starting to think I'm a little screwed here but welcome any input.

You just looking to get the screen to light up so you can implement a way to use the device without the power button? You could try gravity screen or something but first things first...
If its not lighting up on plugin have you tried connecting to a computer and opening ADB and issuing the command adb devices followed with adb reboot. If you wanna go back to bootloader just adb reboot-bootloader. That will restart device so screen is back on and I would turn on the Ambient Display mode so when you pick it up the screen comes on or get a volume power button app or gravity screen app that turns on when you take it out of pocket. Thats all I can suggest and hope any of this helps.

With phone plugged into computer, nothing shows up when I check adb devices or fastboot devices. I guess I'm unsure on what state my phone is in. None of the buttons do anything and nothing happens when I plug my phone into my wall charger (no charge light or screen on). The only response I can get is when I plug the phone into my computer windows makes a noise.
Anyone know what happens when a powered off phone gets plugged into the computer? Does windows make the little noise indicating a device has been plugged in even with it off?

It does not make a noise if its off.. That much I know. Interesting though. Are you sure you have the correct drivers installed for your nexus phone if you are on windows. Go into hardware manager by right clicking on my computer and make sure that its reading it correctly in usb devices without a yellow triangle next to it.

I should have the correct drivers. I just went ahead and reinstalled them through the nexus toolkit. In device manager it says: unknown USB device (device descriptor request failed).
I checked adb devices before all this happened and it displayed correctly. I then rebooted into the bootloader but the fastboot devices command did not show anything. It was shortly after that that the screen turned off. Will the screen normally time out when in the bootloader? I'm wondering if my phone is still in the bootloader with the screen off and both power and volume buttons non functional.

Only thing I can think of is to wait for it to die, then volume down + plug in to pc and when bootloader screen appears issue command fastboot continue and it should boot up. Then get something to remap key or an app. If this all fails after it dies and you restart it assuming debugging wasnt on or its just reading phone as media device of sorts not allowing adb then you may have to get the power button assembly possibly and install it yourself or open the back case and hit the power contact under the button and see if you can get it on. Thats all the ideas I have.
I'd also suggest that after you reinstalled drivers make sure you did a reboot and then plug in the device and also try using a different USB port and or USB cord also as odd as that sounds Ive seen it work before. Im pretty tapped on ideas tho. Do you know if you had usb debugging enabled?

Ok, cool. I'll take a look.
Managed to get it back into the bootloader this morning. So I guess this is a PSA, if your screen times out while in the bootloader, the volume keys will not wake device so since my power button is broken I couldn't wake it. At that point, the phone is in a state where it cannot receive any fastboot commands, even though it is in bootloader with the screen off. What I had to do was wait overnight for the battery to drain and have the phone power itself off. At this point the volume down plus plug in charger trick worked to get it back into the bootloader with screen on. At that point I was able to 'fastboot reboot' back into system.
Thanks for the insight people

Driver issue.
Remove/uninstall the drivers from your PC when the phone is connected.
After that reinstall the adb/fastboot drivers.

N6 - Power mapped to VOL DOWN; turned off and can't get it back on
Hi all, I had to remap my power button - I mapped it to VOLUME DOWN. The other day I voluntarily powered down my N6 at a test center.....and haven't been able to get it to respond since. I do have a Pixel 2 XL on the way - but not that sure I'll want to keep it. The N6 is so sweet.
I've tried holding the volume buttons (POWER and VOLUME UP) for like a minute, but nothing. When I charge it, I see the battery symbol (full) but only for about 5 seconds.
ADB does not see any connected devices. Wug's NRT does not see any connected devices. I'm at a loss and afraid that I've lost my N6 and will have to use the Pixel 2 XL regardless what I think about it.
Any other ideas?

Wow - just got my N6 to boot using this little tip I found on Reddit - https://www.reddit.com/r/AndroidQue...ny_way_to_turn_on_phone_without_power_button/
I was holding down the Vol Up and Power buttons (which are both the Volume bar since I remapped my power to Vol Down), but I hit 'enter' on the 'fastboot continue' text in the CMD prompt just after I plugged in the USB and the battery icon came up. It booted into bootloader mode briefly first, then went into system reboot. Whew!

I think your button assembly is broken and I would replace it. You could try the work around in Broken power button, any way to boot? by altarity, post #3.

Is my ASUS ROG Phone 3 bricked? Screen doesn't turn on

Could someone point me into a direction what exactly the problem is? I have used this phone on unofficial LineageOS 18.1 for a few months but suddently after dropping it from not all to high the screen displayed lines and colors similar to those that you see when you drop your phone into water (there was no water contact and the phone didn't fall that great of a distance, maybe like 1 meter/ 3ft).
My first guess is that the screen is broken, but I tried using ADB to extract some files still on the device but was unable to, especially I can't boot into fastboot or recovery it seems...
When pressing the power button the phone vibrates
Pressing the power button and volume down key reboots the phone (as seen on PC). Holding them down a long time shuts the device off or something. it can only be turned back on when plugged in.
I tried all possible button combinations to enter fastboot or EDL but nothing seems to work (Power + Volume Up / Volume Up + Volume Down while connecting to a PC with USB 2.0).
On my PC the device shows up as "MTP USB Device", everytime, not sure if I'm doing the EDL thing wrong...
EDIT: After leaving the device for a day, it suddenly started to vibrate and repeat the sound I guess plays when battery is low, over and over again in an increasing volume. The volume buttons had no effect as did the power button until it stopped and then didn't respond anymore. After plugging it in again it was back to vibrating once after i pressed the power button. What mode is this??
Any help would be greatly appreciated, not sure if it is even bricked but it seems off that I can't enter fastboot or anything else (like EDL), thanks!

Id tell you to flash raw firmware if possible, a friend of mine had a problem with audio and whatsapp and random stutters, flashing the raw firware for rog 3 may help, sorry but my knowledge aint that great.

looks like your phone is bricked. you can try the below workaround.
[UNBRICK/RAW] Revive your bricked ASUS ROG Phone 3 [23-NOV-2021]
Unbrick your ASUS ROG Phone 3 for free!! Don't pay for this stuff anywhere, it's your device and you deserve the right to fix it yourself. I noticed some people in the community charging upto 50$ for the firmware which should've been free from...

Someone tried this? (ROG2 don't turn on after gaming and charging same time)

Aleatory YouTube videos explaining the problem and possible fixes, I don't recommend this channel, I don't know the YouTuber.
ROG2 here turns off and not power on again after gaming and charging same time (it's dead). Someone here tried one of this with success?

Reballing the CPU

Hello there!
I have no experience with your problem. Just going to say that from the top. I've never torn a phone down, and when hardware components need replacing that's when I usually decide I need to pick up a new phone.
I just recommend you make sure the phone you're trying to fix like this actually needs it. I've messed with my tencent rog ii quite a bit lately and I have had the phone go completely black - thinking I had thoroughly destroyed my phone, but I was able to get it running again.
It's possible that the complete "power off" that you are reporting is the phone being in EDL mode as the phone gives no indication whatsoever that it is on when in EDL mode. As a hail mary maybe you should quickly try this before tearing your phone down.
go to this guide, and download the zip file in the main post.
Repair your ROG2 phone with EDL mode，Official firmware！
Success is disgusted by some people, and will not share any files for free in the future.
forum.xda-developers.com
extract the zip, then go the the folder "qpst.win.2.7_installer_00453.2" and run "QPST.2.7.453.msi" - this installs the drivers necessary to communicate with your phone when in EDL mode (this may not be necessary, as your pc may identify a usb connection without this, but just to check 100% I'd install the drivers anyway.)
charge your phone for at least 30 minutes. just to make sure it's got juice.
use a DIFFERENT USB-C <-> USB-A cable than came with your phone (pick one up at the shop if you're not sure. ALSO plug your [charged] phone into your PC using the side USB port on the phone (Not the bottom usb port). This is because ASUS's cables don't seem to support flashing, so I'm suspicious if they'd work appropriately in this case, and because the side port is the only one that works for flashing and the like.
now open device manager (press windows key, type "device manager"). with that screen open, plug your phone in. On device manager you're hoping that a device appears under the menu "Ports (COM & LPT)" probably named something to do with Qualcomm.
if nothing shows up, unplug the usb port from the side and hold all three side buttons down for 20 seconds (vol +, vol -, and pwr) and keep an eye on the upper left side of the device where you MAY see a red light flash indicating signs of life. then plug it in again. if nothing happens unplug the phone, and hold the power button for 5 seconds, and plug it in again. if nothing happens, unplug it and try holding down just power and volume up for 20 seconds, then plug in again. If nothing happens, try power and volume down for 20 seconds, then plug in again. (you see where I'm going?) just make absolutely sure your phone has a hardware problem and can't connect to your PC in any way before performing surgery. If the device does show up under this "Ports (COM & LPT)" device it means your phone OS is thoroughly trashed. check out that same guide I linked, as well as this youtube for some ideas how to get it going again.
If your phone doesn't connect no matter what, and you're certain you've gotta get into the hardware, then I wish you the best of luck. I really wish I could be of any further assistance with regards to hardware. maybe if you do take that road let us know how it goes.
good luck!
