Phone won't turn on anymore - Desire 820 Q&A, Help & Troubleshooting

Hello.
I was trying to root my phone yesterday and during the process I accidentally deleted the system partition. As I was trying to flash an OS today, the phone turned on into recovery. When I figured I have the wrong .zip, I powered it down, and literally the next second, as I was trying to turn it back on again, it would'n do so. Even if I plug it into an AC, the LED won't be lit.
What is happening? Please, please, please help.

Possible Brick? Need urgent help!

Okay,
So I've read through previous thread about people's "bricked" HOXs. I've read the appropriate fix threads but nothing works for me.
I am now stuck in what seems a bootloop. When connected to a power source, the phone stays in bootloader and the red LED light stays ON. It doesn't flash, it's just solid. Also, when either end of the USB cable is disconnected, it stays on. I can't boot to recovery, or get stuck at the splashscreen to charge up. Battery is below 20%, so fastboot flashing doesn't work, and also can't install RUU on it. Whenever I power down from bootloader, it powers back on automatically at the "HTC Quietly Brilliant" screen with red text underneath saying something about this build being for development purposes only. Also, I relocked bootloader in a hope to run RUU, but only realised after relocking that battery was at a low level.
I have had two sleepless nights now, and I'm hitting the hay tonight. I am willing to try anything when I wake up to fix my phone. If anybody can help, it would be extremely grateful! Sorry about the length, I tried to explain in as most detail as possible.
If I have missed anything, please mention it and I'll let you know.
Many thanks in advance.

One of my friend was in the same situation and this method helped:
Download this:Android.zip
Unzip somewhere into your pc.
Download this:Battery.bat
Take the Battery.bat into the Android.zip folder
Connect your HOX with the pc(bootloader/fastboot),then run the battery.bat file.
Whait while your device will be charged enough(it needs 1-2 hours).
When it is charged you can push recovery,or run RUU-as your liking...

Desire dead

Sorry if for making a new thread about this, but I need a little help.
What happened is this:
Got home;
Battery went dead;
Put it to charge;
Turned the phone on;
System loaded;
Got every force close imaginable;
Phone went off;
Tried to power it on, nothing;
Got to fastboot;
Recovery gone;
Tried to flash a new one via Android Flasher;
Phone froze;
Now, no reactions to any button, and the phone just won't turn on.
Black screen. It charges though.
Also, the ROM I had was An-Droid 2.2.0. data++ HBOOT, meaning I was S-OFF.
Is it completely dead, or is there something I can do? I would appreciate the help on this one please.

[Q] Boot loop then restore upgrade error fail

Here's what happened to my (not rooted) G3
The phone has been weird for a couple of days, rebooting randomly once in a while, but working fine whenever plugged onto a power source. Google told me it could be a battery related issue, so I bought a new battery online (and I didn't get it yet).
This morning the phone entered a boot loop, even when plugged in to any power source. Google this time told me I could put the phone in "download mode", then restore upgrade errors via LG PC Suite. I try to do that, and the phone actually goes into download mode, but I'm not able to restore upgrade errors with that ugly piece of software because it keeps "losing" my phone usb connection. I unplug and plug it back in several times, the phone seems to make progress on the firmware upgrade screen but I see a red ASSERT error on my phone at around 15% of recovery.
Now whenever I turn on my phone and try to put it on download mode keeping the volume up button pressed, the screen will just go straight into firmware update, warning me not to unplug the usb connection, even if the phone isn't plugged. I'm able to start a restore but again the usb issue comes up and the phone is totally frozen and stuck to that firmware update screen. If I want to turn it off I need to remove the battery.
I'm doing this because I would love to recover some data from my phone, otherwise I would have done a hard reset or a flash of some kind
Please someone help me before i throw this piece of junk out of the window
Nobody able to help me in any way?
bump =(
Contact LG in this case. Might be faulty NAND memory. If it is then it will probably be impossible to get those files back...but they will replace it and fix the phone. (if it is under warranty that is...)
BTW if you take out the battery during flashing...you may hard brick the phone...then you're technically more fked

Zenfone 2 551ml Restarting

Hello, guys, hope someone can help me, here's what happened:
I had cm13 running on my phone, normal, sometimes it restarted itself, but I guess it's normal,
My phone bricked these days, he restarted and didn't wanted to turn back on, so I enterted the twrp and tried to do something about it, ( wiped cache, data, normal stuff ), that's why it got bricked,
It was showing that usb logo, after lots of reserch I was able to unbrick it, but somehow the phone keept restarting itself,
For exemple, I instaled the original rom, when I was configuring it for the first time, bom, restarted,
Changed to CM13, was using it normal, then, again, restarted, and only turned on when plugged to the power,
Otherwise, he'd tried to turn on, but when the blue robot appears he turned down again, it was only possible to turn it on when plugged to the power.
I tried everything on the forum, flashed it a thousand times, with diferentes raw files, recovery.img, boot.img, everything,
Don't know what else I could do, can't use my phone anymore, could someone, please, help me?
Thanks a lot!
If you did all what you said you did and nothings changed..I would think it's hardware related by now .
I was thinking something like the battery or battery connection.

Is there something I can do about it? Or to discover if it is really the battery or hardware related?

Am I stuck in a bootloop? Able to restore w/ Download Mode/KDZ!

Hiya!
I accidentally spilled a bit of water on the back of my phone and was quick to dry it off, but everything seemed to still work great.
Later on, I plugged it in to charge and it turned off once plugged in; I attempted to turn it back on but was met w/ a black screen (no lights/buzzing, etc). Then, I popped the back cover to find the bottom insides (where the headphones are, nothing above it) were a little wet. I took out the battery, dried everything off, and without thinking (probably my first mistake) I turned it on. It worked! But then it wouldn't go past the LG logo. So, then I tried 2 more times turning it on, same thing: bootloop.
I then tried to go to TWRP, that worked once, it crashed (It was a KERNEL error) then it went back to a bootloop.
"Fine," I thought, "Will just see if download mode works, maybe something became corrupt." Thankfully, I am able to go to Download Mode and flash H81120o_00_0613 successfully (from what LGUP says) , but after flashing, it goes to the little android logo like it is going to optimize apps, reboots, then it just shuts off.
Am I just screwed now and have the dreaded bootloop or is there anything that can be done?
Any help would be greatly appreciated!!
*edit*
Can't believe I forgot to mention, but it is a H811!
Also, after the flash, I am able to go to factory reset, it goes to the little Android logo guy again like it is configuring something, reboots, I receive a pulsating blue light, then it just turns off.
