HTC Desire 820s WONT BOOT - Desire 820 Q&A, Help & Troubleshooting

Hello. I decided to reboot my phone after seeing that my SD card was unmounted. I removed the SD card, and long-pressed the power button, and selected RESTART. After waiting for a few minutes, my phone won't boot. I thought the battery must have drained so I charged it to a wall socket. Nothing happened. The powerbank recognizes the phone when I plugged it, but the phone won't get hot (so I think it isn't really charging?). The LED light won't turn on. Laptop doesn't recognize the phone, too. I tried to hard reset it by pressing the power button + down button, but nothing happens. Everything is black. Please help! Thank you.

Cold reset is on vol up + power I think

Yeah, I did that. Didn't work. Apparently my phone got soft-bricked. Haha. I went to a repair shop and had it fixed. Thanks!

Tilt 2 Will Not Boot

I have an ATT Tilt 2, approx 7 months old. I was running the EnergyROM, but I forget which one. This morning, the battery died, I plugged it in too charge on my laptop. I got a dialog box that said the charging power was insufficient to run the device, and it turned itself off. I let it be for a while (hour or so) then tried to reboot. It would not respond to the power button, so I hit the red reset button with my stylus. It booted, but not successfully. The phone got caught in what I can only describe as a loop. It would start the boot animation, then fail. It would stay turned off for a few minutes, then spontaneously try to boot again.
I held down the reset button again........nothing. Power button.......nothing. So then I tried to wipe it, using my micro SD card. I was able to get the phone into bootloader mode, and told it to apply the update by pressing the volume key. However, it still loops, except now it goes into the bootloader, except there is an error message in the bootloader screen, buried under the text. FWIW I am using the Olinex HardSPL.
Any help is GREATLY appreciated
EDIT: This only happens when it is plugged in. When it is on battery, it is completely unresponsive. No power button, no reset button, nothing. All i get is the amber charge light

That means the phone is NOT charging the battery. Did you try using another USB cable? If so, did you try another battery? If you tried that too and it still doesn't work, that may mean that the charging circuit is dead and you will have to either get that one repaired or get a new phone

Try charging it from the wall plug. Your laptop port is not putting out enough power. Let it charge until the green light comes on.

Can the charging circuit be replaced? Can i repair it my self (buy parts on ebay)? Would you happen to know much will it cost to repair it from AT&T?

[Q] Desire won't turn on after market crashed

Hi there!
I have got a really strange problem with my desire. Here is what happened:
I opened the market app whilst using mobile internet. The app froze on the loading screen and the phone was unresponsive.
I pulled the battery and powered on again. All seemed fine.
I opened the market again and the exact same thing happened, only this time I can't turn the phone back on.
I have tried pulling the battery. Tried plugging the phone into a charger without the battery then reinserting the battery. Tried charging the battery until the led went green, still no luck.
I had plenty of battery when this happened.
When the phone is on charge, when you press the power button, the led goes out, but the phone does not turn on.
Does anyone know what this might be? or how I can turn my phone on again?
Thanks all!
Bump, does anybody have any idea?
The only idea I have is a hard factory reset:
Try to start phone with pressed volume down and power button, navigate with volume button to "clear storage" and enter with power button.

Wipe dalvilks cache in recovery

Thanks for the ideas guys. I actually can't power on the device at all. Can't boot into recovery, can't do anything as far as I can tell.
Any other ideas?

What the hell are you doing to ur desire?
Try removing battery for a minute, then re insert it
Then press volume down and without release it, press also power button and wait 5 seconds with both pressed to see if it boots into bootloader and go into recovery too

I removed the charger before putting the battery in. I saw someone recommend it on another forum with a similar problem.
I have tried to get into recovery after leaving the battery out for 12 hours, after charging the phone until the led was green, it seems I've tried everything to get this to work but nothing.
I'm really annoyed as well because I'm 2 weeks out of warranty. It just seems so odd that a software crash could cause all this.
Anybody else got any ideas?
what happens when you press.. volume down and power.. can you see the hboot screen.. is your phone recognised in ur pc?

Absolutely nothing. Totally blank screen, no vibrate nothing. Phone is not recognised by pc. The only things that happen are the following:
When plugged into the charger the orange led comes on, and eventually turns green.
When plugged in, if I press the power button the led turns off, but nothing else happens.
I'm totally at a loss. I called HTC and am sending it in for warranty repair. They said they have extended the warranty to 2 years which is a bit of a turn up for the books, so hopefully they will fix it for free and not charge me for it
Try this:
Boot into hboot
Count (slowly) to 20
Then press the power button once
Connect the usb
Start command prompt
Type "fastboot devices"
For this to work you need to install Android SDK see here http://wiki.cyanogenmod.com/wiki/Howto:_Install_the_Android_SDK
If you get anything than somebody can help you. I read somewhere about this issue but I can't find it anymore.

[Q] Phone won't boot

Yesterday my phone was taking a really long time to do something simple (open an app I use all the time or something) and it was unresponsive to the normal power button function, so I pressed and held the power button until the phone turned off. I put it back in my pocket and forgot about it (at work). A few hours later I went to use my phone and it was nearly entirely unresponsive. If I press the power button it vibrates briefly and then does nothing. Same behavior after plugging in USB for power and after letting the phone charge for a while. I've also tried removing and replacing the battery and removing the external SD card.
I'm also not able to boot into recovery (TWRP installed). When I press and hold the volume up and down keys while booting the phone, I see SAMSUNG flash briefly and then the phone seems to shut back off.
Any ideas for recovery?
Thanks
Never mind, figured it out

It would be nice if you let us know what you did to fix it? Because my phone is now doing the same thing.

GNexus wont turn on & I cant reboot :(

3 days ago on my b-day I charge my phone only to power it on and have it immediately shut off on me. I plug it into charger and it was still fully charged so i turn on agian and it does the same thing it will just immediately turn off on me. Now its gotten to the point where when i try to power it on the word google pops up and it brightens after abotu 3 seconds then phone turns off and continue to charge. The phone battery indicates it is fully charged however it wont turn on. May i remind you my volume down button does not work so i can not Volume keys and Power button reboot. Plz help
I wonder if the hardware has broken somehow? If just the power button broke, this post says to remove the battery, plug phone into computer, then insert battery: http://forum.xda-developers.com/gal...rnative-to-t1731128/post65166854#post65166854
If only the software has broken somehow, maybe you can flash a new ROM from the beginning using one of the nexus toolkit apps which automate everything for you.

Phone just doesnt turn on

So I was at 3 percent and plugged the phone in the car charger. I just texted and the phone got stuck. Waited for it to start being normal again but it didnt. Suddenly it shut down, restarted and got stuck on the LG logo. I waited and waited and finally removed the charger and took out the battery. I then plugged the charger back in but the screen would just not light up. Tried holding the power and volume button key at the same time, but to no avail. Took the battery out and kept the power button pressed and then put the battery back in. Still wouldnt work. I then connected the phone to my laptop and pressed the volume up key to enter into download. Nothing.
What is wrong with my phone? The phone is just DEAD. It doesnt even light up showing that its charging when i put the plug in. What should I do?
The phone is rooted. Its on stock rom btw.

Please do some search and refer to the bootloop thread as there is no need to create new one. since there are many discussions on this topic already. Try freezer or baking method and see if you can at least get it to boot to have your data backed up.
