[Q] how do i save my phone? stuck in empty battery screen

i was previously using this rom, [ROM][MIUI][21/10] cMIUI 2.10.19 [4.1.2][AOSP][OTA][Aroma][Multi][Super Stable] and tried to flash it back to the stock rom (DXLPB).
i used odin to flash it back and apparently the operation failed and i got into the screen where it shows the "firmware upgrade had encountered an issue...." message.
when i tried flashing the rom again the operation always fail because the usb keeps disconnecting every 20 seconds and connecting again.
so i tried flashing the rooting file ( the one that i used to flash in odin in order for it to root ) and this time my phone went into recovery mode.
i cleared the cache and wipe the phone data and rebooted it.
apparently the phone doesnt go into any screen anymore other then the empty battery icon when i plug it into the com. if i unplug it, the phone will be stuck in the same screen until i take out the battery.
usb is not detected, odin not detected also.
i cant switch it to download or recovery mode either.
i tried using the heimdel package but it wouldnt work because the phone cant be detected either
is there anyway to save my phone??
please help! thanks in advance.
i tried getting it into download mode and the screen shows "LOW BATTERY!! CAN'T DOWNLOAD!" screen. unfortunately, i cant seems to charge my phone also. plug into the pc and charger for hours, doesnt seem to charge. its not the cable's fault. i got many cables, tried all of them. any help??
Try another battery (best charged). If you have an old backup use it.

[Q] LG P760 [Optimus L9] Stuck on LG screen/do not turn on.

Hello Yesterday i have upgraded my phone ROM.
First have unlocked the bootloader.
Next, followed this video to upgrade to Android 5.0 AOPS build:30-11-2014 by Artas.
It was great and useable while i did not installed a new CWM.. (CWM 6.0.4.5 Touch by Pollos).. after that, the phone is stucked at "LG" logo and while i charge random times reboot..
Earsed all with fastboot, and now the phone is not turn on while i charge or try to turn it on..
I have got this problem earlier with an other android version (sercurity error) and the S/W update was good.

Hello
is there any chance a kind person can help me with this dead stick?
a few information about this phone:
- as far as i was told, the phone died after an update
- when i plug the phone to the charger nothing appears on screen
- when i power the phone nothing happens
- when i volume up + power the phone nothing happen, same with volume down + power and volume up+down+power
i have installed the lg tools and using the imei downloaded a 600+MB package which should be the restore image of the phone but when the procedure starts to flash the image it gets stuck at 4% trying to connect to phone without any luck
if anyone has some ideas to give i would be very happy to try them!
Click to expand...
Click to collapse
Now.:
When i try do S/W upgrade with the "LG Mobile Support Tool", it stops at 4% and the phone disconnect itself from the PC.. the installer goes (without the phone plugged in) 4--->8% and if i turn again my phone to download mode, go to 15%.
At 15% again disconnect and the installer say "Error, try to unplug USB and remove battery and try again......"
I have tryed KDZ offline flashing but it is force quit when i click "Start"..
Tryed:
Official support tool - Say "You have already installed the latest version (V20H). If i try to "Upgrade errors fix", it stop at 15% as i said..
Fastboot - earse boot, system etc.. after that again upgrade, but stop at 15% and phone turn off.
LG Flash tool - these 90% exit with some error before i can start anything..
I hope you can help and understand my bad english:'D
Did you invoke "Download Mode"? If i remember, this requires switching the phone off, and attaching it to usb while keeping volume up or down pressed, and will show a special screen, if successful.
Download mode is even more basic than fastboot or adb, and the final line of defense, before throwing the phone away.
All LG tools require the LG usb drivers. These at least no longer recognize the phone with Artas' CM11, except for when in download mode. Then Windows should auto-install a virtual COM port. For ADB and Fastboot you need different drivers then, like those from the Google SDK. But with these the LG tools won't work, not even the sync suite.
