G2 Boot loop, with download mode stuck - G2 Q&A, Help & Troubleshooting

Hey
Recently I tried to install the 4.4.2 KitKat official update, but didn't realize it would cause problems with my currently installed custom rom. I'm kind of a noob with these things. So now my phone is a mess. yay.
What is now happening, is that:
Phone goes into endless boot loop, showing LG icon. Top left LED blinking green and blue in a wave-ish pattern. Have to keep power button down for 20 seconds to turn off phone completely (with usb unplugged).
Recovery mode brings me to TWRP. From here I can do the "dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota" but no success. It will continue its boot loop upon restart.
Download mode brings the phone to firmware update, where it never goes beyond 0% updated.
I wiped all data from phone, but no success with recovery.
So guys, any ideas on what to do about this?
Any help will be appreciated

HELP!!! My Galaxy S5 G900V doesn't enter NORMAL Recovery Mode!!! & Stuck in BootLoop!

HELP!!! My Galaxy S5 G900V doesn't enter NORMAL Recovery Mode!!! & Stuck in BootLoop!
I think its kinda soft brick!
:crying: Like the heading says! I am stuck in continuous Reboot LOOP!!!
And something strange about this problem!
Let me brief it out!
Firstly tried to install the latest Lollipop firmware USING ODIN v3.09 which is OG5 AND I SUCCEEDED with a PASS!
And then when I tried to restart , it got stuck in "Recovery Booting...." blue text on top left corner of the screen followed by CONTINUOUS BOOT-LOOP OF SAMSUNG SPLASH SCREEN! Not EVEN REACHING VERIZON Boot Animation which is followed by every 2 VIBRATIONS & interval of 5-10 seconds of each loop!!!
And one more thing is I cannot enter the NORMAL RECOVERY OPTION MENU! Instead I ONLY
GET "Maintenance Mode Recovery Menu" Which has 3 options
1 Normal Boot
2 Factory Reset
3 Safe mode Boot
But Sadly and STRANGELY I CANNOT GET THEM TO WORK EITHER!!! As soon as I PRESS HOME BUTTON AFTER SELECTING THE OPTION FROM ABOVE IT DOESN'T EXECUTE IT INSTEAD GETS OUT OF THE "Maintenance Mode Recovery Menu" & Continues WITH BOOT LOOP sometimes followed with Recovery booting text ! Which I believe happens when I Press Power and any of the Volume Buttons!
So I ALSO TRIED FLASHING THE OE1 Lollipop Verizon Update via ODIN WHICH ALSO PASSES WITHOUT FAIL! BUT AGAIN SAME RESULT WITH BOOTLOOP!
AND ANOTHER STRANGE THING IS THAT WHENEVER I PLUG IN THE BATTERY THE GREEN LED NOTIFICATION LIGHTS UP SOLID PERSISTENTLY WITHOUT BLINKING! UNTIL THE BATTERY IS REMOVED OUT OF THE PHONE!
SO I reallly dont know what the problem or fix to this issue! But I request you people to help me out as soon as possible!
FYI
I can BOOT INTO DOWNLOAD MODE! I can BOOT INTO Maintenance Mode Recovery Menu!
I searched every forum regarding this issue but to no avail!
THANK YOU!

Stuck in bootloop, plz help

Hey guys,
Yesterday evening my phone kept restarting.
I let it go untill the battery reached 0.
Charged it and it kept doing it.
I tried reflashing it with stock rom.
Now it reboots, starts up into android system update thing (blue screen) reaches 32.
Then it says erasing, restarts.
Now its stuck in bootloop i think.
After showing the model screen, it says no command (again with the blue screen) then it restarts.
I tried flashing different stock roms.
I can boot in download mode but i cant seem to get into recovery mode (yes i've really really tried this.)
Any1 can help me? all help appreciated.

Bootlooping when not in charge..

Started Suddenly my a6000 plus went off and was not starting at all. I was running RR rom. I didn't install or modified anything prior to the problem. The interesting part is when I put it on charge and try to start, it starts with bootlooping but after sometime boots in system. But can't get into recovery. Now after starting if I plug out the charger it immediately shuts down and goes into bootloop. Now without putting it on charge it never goes into system. I can't get into recovery, only bootloader is showing up and fastboot commands are working but not adb. I tried Qdownloader but pc isn't recognizing phone as driver is not getting installed. What should I do?
Have you found a solution? I am facing a similar issue on stock, non-rooted. It keeps flashing the boot logo but when connected to power it boots in system. As soon as power is removed it keeps blinking the bootlogo aka bootloop.

Need help to unbrick my phone

Hi,
I have a Note 4 t-mobile that is "brick" right now. and I hope if anyone offer assistance.
It is running Android 6. Ever since the last upgrade the phone would freeze and reboot on its own. I fixed that problem by installing Wake Lock. After that it would still experience sluggish at time but the phone is still very much usable.
Lately, after watching a bit of streaming video the phone would slow down so much that a reboot is needed. But yesterday my last reboot turned my phone into a brick. After that reboot the phone rebooted itself to the download mode. So I took the battery out, waited for a few minutes and put the battery back in and started the phone. Instead of booting normally the phone displayed the message including "set warranty bit: recovery" and then followed by the flashing TWRP splash screen. By "flashing TWRP splash screen" I mean the TWRP splash screen ( with the TEAMWIN logo) would be shown on the screen for a second, then the screen black out for a couple of seconds, then the splash screen is back on for a second, and the screen black out for a couple of seconds, etc, and never successfully boot into TWRP recovery. I had left the flashing splash screen overnight and nothing changed. Connect the phone to my pc via usb and fastboot wouldn't recognize my phone when phone was flashing the TWRP splash screen. So I tried to flash TWRP again by starting my phone in download mode "volume down + power". When I connected my phone to my pc Odin recognized my phone. But when I tried to flash a custom recovery (TWRP or CWM) it seems the download started but never finished (on the phone I could see the progress bar started but never progress further).
Any suggestions would be greatly appreciated1
Additonal info
I just wanted to add that my phone is still running the stock ROM.
Problem solved
Problem solved. Once I used a different cable and the download process actually worked and I was able to flash stock ROM using Odin.

Le Pro 3 - Stuck in a bootloop recovery mode and fastboot not working.

Hi guys,
After googling it I tried booting it in recovery and fastboot mode but none of them work, when I try to boot in those 2 modes I get a screen with "recovery mode" written for 5 secs then it goes back to the normal boot screen and then turns off and starts to bootloop again the only way I could stop it from boot looping was by pressing the power button + the + and - buttons, so yeah if you guys have any idea how I could fix this or how I could recuperate my data please help, also it started bootlooping during the night while it was charging it was very hot when I took it, last thing when I try to go and charge it there is not indicator that it's charging.
Thanks in advance for your help !
much love
Mathias.
Kind of the same issue here.
Yesterday, I was using my phone while it was charging (low battery), and suddenly : freeze then power off and stuck into a bootloop.
It did it all the night until no battery, now when I plug it the charging Led is not lighting, and stuck in a bootloop.
Tried to flash TWRP vi fastboot mode : success but impossible to boot into recovery mode, as you described.
Affraid of the battery has died...
Flashed wrong orange state zip
Same to mine, my device was x651 and i flashed an orange state zip file intended for le 2 x620 without wipe and after flashing it from recovery , I rebooted the device, now its powering on and off on a dead screen and only long vibrates, how can we fix this? Please help
Not sure if this will help, but I ended up with a perpetual boot loop on the phone and wrote it off as broken and got a new one....a year later, I plugged it in to see if it would even power on so I could trade it in and VOILA, it boots up! What the hell? So my suggestion is maybe to let the battery run ALL the way down and then a long charge first.
