[Completed] [Q] LG G2 AT&T Bricked Pretty Badly

I have a rooted LG G2 (AT&T) running Android 4.2.2. I rooted it and then tried to install TWRP recovery. After attempting to flash a TWRP image using Flashify, the phone rebooted showing the Android guy with a red triangle (so basically the installation failed). I held down the power button and the phone booted up like normal.
Alright, now later down the line the phone received an OTA update (probably Kitkat). When the phone "booted", the LG logo flashed on the screen and then stayed black (the backlight was still on). If I hold the power button+volume down, the phone will just reboot. Without really being able power down the device, it seems I cannot get into download mode. Also, if I hold down power button+volume down for a long time, the notification LED will blink red (5 times *stop* 5 times...) until I let go.
Eventually I tried the power button+volume down button multiple times, pressing it in different timing intervals and managed to get it into factory reset mode! I followed the prompts but alas the phone will still not boot normally and the screen backlight is still on.
I hope this is the right forum, I need help fast.

Essentially, yes. This isn't a tech support forum. It's simply to help you find what you're looking for or find where to look for further information. Copy and paste your question in there. No need to have this one deleted though.

[Completed] Android boot loop - is my device dead?

Hello All,
This is my first post at this forum.
I've come to a point where I'm on the verge of giving up.
A few days ago my Nexus 5 entered a boot loop without me doing anything special with it - it was just in my pocket.
All see is the google logo for a few seconds , then the screen goes down for a few more, and back to the google logo.
I'm able to go into fastboot by hold down the volume down (only) button when this happens, but the boot loop happens when I choose to boot into recovery mode.
My device has an unlocked bootloader.
I have fast boot access and no ADB (ADB wait-for-device doesn't work).
Went over a tutorial from androidforums.com and flashed a completely new image using fastboot.
The entire process worked, but the phone is still at the same state.
I've read that there is and issue with the power button on these devices - so I tried all methods of knocking it against stuff without success.
I've taken it to a lab nearby and the guy there was sure it was the power button. He said he fixed about 50 of these already - after a few hours he called me up and said he had replaced the power button 3 times and he's giving up.
in short , this is the current situation :
1. Device stuck in bootloop - only google logo is seen
2. can boot into fastboot (and have fastboot access from PC) but can't boot into recovery
3. flushing a stock succeeds but won't help
4. power button seems o.k.
I am about to call this a bricked phone and look for a new one but something inside me tells me that this might still be a software issue and can be fixed.
I would be happy to know if there is a way to know what is failing in the boot sequence. or maybe load a debug application on to the device to check the HW. I've yet to find any help in that direction.
I'm a software eng. working in the cellular comm. field, so I'm up for anything that anyone has in mind.
Thanks,
Ran.

Hello, and welcome to XDA!
It does sound like a hardware issue and it could be the power button, except for one thing: wouldn't a held down power button in fastboot cause a shutdown as well? Maybe not, but I thought I'd ask that.
At any rate, better to get an opinion from someone who actually has the deivce. Please create an account (so you post in other forums) and then post in this thread (can copy and paste from here):

Hope this helps, and good luck!

[Completed] Permanently Bricked HTC One M7 (Been trying for 7 hours)

Hi,
I am pretty sure I have permanently bricked my phone, my PC no longer detects it (it used to, and I have tried reinstalling drivers several times)
When I turn on my phone, I see the HTC Logo, then it goes to a black screen, the only way for me to leave this black screen is hold power button and wait for capacitive keys to flash 115 times before it shuts off completely...I have access to Recovery Mode and am not rooted.
Any help is greatly appreciated as I've been trying to fix this for almost 8 hours now
(I have a HTC One M7 running OS~7.19.771.21)

[Completed] Bricked tablet

Yesterday i messed up quite a bit with my device Allview viva i7g after i've unlocked my bootloader and accidentaly i put the wrong recovery ( the one i put minutes before flashing the tablet on my olther device which worked just fine) the problem is that i can't access the recovery( as expected) and the device can't go to bootloader without using the adb command.
(belive me i tried all the possible combinations) it can turn on stuck at the logo the device battery can be unlugged very easily so its not a big deal taking it off, and also if i keep pressed vol up and power it goes to a white screen for a few secs.
this is all the info i could think of for now feel free to ask me olther info if you want.

Lg g Stylo, "no command" please help me!

Please guys I need your help!
Phone model: Lg G Stylo h631 T-Mobile version.
Today I was using my phone and after finishing a call, my phone started to update itself. Then I received a error message. After that, I get stuck with a dead android guy on the screen, and I get the message "no command". I try Different combinations of buttons to solve this problem: Volume Down + Power release and then press the buttons again went the LG logo appear and have no luck. Then I try Volume Up + Power, also have no luck. I think I try almost every possible combination an nothing is working.
If anyone has any idea how to solve this issue please help me. Any help would be appreciated.
(Sorry for my bad English)

Make sure you download or have downloaded and installed the LG drivers from the LG website or any other reliable source or your phone will not be able to recover.
Unplug the phone, take out the battery and once the phone is completely off, replace the battery. Keep the phone powered off and unplugged. Plug a data capable (the usb that came with the phone is best) usb into a PC. Press the VOLUME UP button and HOLD it WHILE plugging the usb into your phone, (The PC should already be connected before plugging in the phone) continue to hold the VOLUME UP button until you pass the LG splash screen and you should then be in DOWNLOAD MODE. From there you can reflash the stock ROM that came with the phone. The stock ROMs are pretty easy to find here on XDA.
If you don't know what flashing a ROM is or means then XDA has plenty of guides for that as well. To return to stock you will need the LG Flash Tool or LG UP depending on which version you want to flash. Marshmalllow uses the LG UP program and Lollipop uses the LG Flash Tool. You can find guides and all the tools\software you will need to fix your phone right here on XDA or a little Google searching.
