Hello, my Z3v was downloading/installing the Lollipop firmware over night and when I checked in the morning the phone was stuck in boot loop.
Following the SONY logo screen, it immediately goes into "Error - Update Failed" and it keeps repeating the loop if plugged in to the wall charger (if not, it shuts off shortly after). I have tried recovery mode but it doesn't work (tried both Power + Volume Up and Power + Volume Down), it immediately goes to the dead android robot with "Error-Update Failed" screen and repeat.
I have tried PC Companion, however there is no Z3v in the available device recovery list, and based on the search neither Verizon or Sony is providing support for the device? which is just plain ridiculous. I can get as far as having the "Upgrading, do not disconnect device from PC" screen when connected to the PC Companion while I have to choose the restore device (again, no Z3v so can't proceed any further from here).
My question is -
1. Is there a way to access the folders in the phone to retrieve data from it? My guess is not while in boot loop since it keeps disconnecting but a way to do it on the "Upgrading" screen?
2. If I don't mind the hard wipe, is there a way to get this fixed? Verizon technician gave up after 3+ hours of trying...
Thank you so much!
Just Turn off your phone and flash it with Flashtool then it will comeback
Thanks for the reply. The Verizon technician told me he tried flashing it several times with no luck. And personally, I've never done it myself. Is there a step by step guide on how to do so? Thank you so much!!!

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.
Hi guys. So I have been going through xda and Google for hours and hours trying solutions, to no avail. I almost never post on forums for help because I can usually find the solution. Not this time. This is my last resort next to throwing my phone out a window or praying for death's sweet release.
The facts: I have a rooted Xperia Z3v. I tried to upgrade TWRP in order to follow some directions on upgrading to Nougat. I flashed TWRP from 2.8.X.X to 3.X.X.X. I rebooted and it never made it to the Sony logo. Now, if I plug the phone in to either a wall socket or PC it vibrates, endlessly at three second intervals, each time with red LED. If I try to enter flash mode, then its the same but with a brief green led after the red. I can enter fastboot (the only way to stop it vibrating while plugged in) and my PC sees it, including Flashtool, but since my bootloader is locked permanently, I can't really do much with it.
When plugged into the wall-charger, I noticed that the charger's LED changes from "Active" to "Inactive" with every vibration. I'm pretty sure I'm in a reboot loop. The screen is totally dead and there's no logo, but every three seconds it kills it self and comes back.
I have tried everything I could think of.
What I have:
I have the stock firmware ready to go
I have TWRP backups on SD card and PC
I have Flashtool
I think my drivers are good, but not 100% sure
I can fastboot
I'm at my wit's end and losing hope.
Please, I'm open to any suggestions at all.
Hello, first thing, sorry if i dont make sense, i am still learning the language.
Ive been searching the forum but i could not find an answer to this problem. I checked a few guides here about how to return my phone to stock (Verizon vs985 0817 ?). Well, this is what happened:
1) Yesterday my phone turned off, no idea what happened. After that, it was locked in a boot loop.
2) First thing i tried, LG pc suite, but it did not recognize the phone, it was restarting a lot.
3) After that, i see in a post about doing a factory reset, i did it but nothing changed.
4) I found a guide to reinstall the firmware on this site (ive done that with 2 samsung tablets i have and i did not have any trouble).
5) Next step was wiping cache, installing LG dll's on my computer and tried to install a firmware with LGflashtool2014 (VS98547A_01_0314_ARB01.kdz).
6) The phone started the update and stopped around 23%, the application lost communication with the device (nothing was touched or moved).
7) The phone then entered into download mode (firmware screen) even if i turn on the phone normally (no volume up).
8) TL; DR; HERE IS THE REAL PROBLEM: When i turn on the phone i see the firmware update screen, then after a few secs, 13-15 the screen turn off again. Even if i try to reinstall another firmware, I get the pop up message about losing communication with the device.
Things i tried:
Another battery (original one was about 88%)
3 different cables.
Tested on 3 Usb ports (3.0 and 2.0)
Reinstalled usb drivers, nothing.
Changed port to com41 (was reading about it on another post).
Wiped cache again, factory again.
Am I really out of options?
Hi all,
To get right to the point, my phone doesn't switch on, and I cannot get into recovery/download mode.
The story:
After my apps kept on crashing for no reason, I restarted the phone. After the restart, when it asked my pin, the google app kept on crashing and the phone completely froze up.
Here is where I suspect I made a HUGE mistake. I Took out the battery and started up the phone again. It immediately told me that the system is corrupt and "cannot be trusted".
I continue the boot process, only to land in a boot loop. I take out the battery once again and restart the phone.
After displaying the LG logo, it just turned off. And that was the last time I could get it on.
I tried booting into recovery, but the phone won't even switch on to begin with.
Absolutely no response. Screen stays pitch black.
I tried doing it with the USB cable in, same result. Nothing.
I also read up on the different combinations to get into download mode to no avail.
Stock ROM and firmware installed, no mods whatsoever.
Android 8.0
Can anyone please suggest anything I can do to save my device?
Hello everyone, I have an archos 50d helium Android 5.1 Lollipop, which practically when turned on remains locked in the logo screen, the one with the archos logo and does nothing, does not continue and therefore does not turn on. I turned it on with the vol + key entering in recovery mod and doing the various wipe cache, total formatting, but nothing has changed, the phone remains locked. I tried to download CWM and do apply update via sd but any file I put (even the phone's firmware i tried like 10 .zip file) has always given me E: footer is wrong, signature verification failed, Installation aborted. While trying to turn it on with the volume key - it does nothing and does not go into download mode. As soon as I put the charger on the phone, if it is off, it turns on and remains locked in the logo (Archeos), but I think it charge because it stayed for a long time in recovery mode or in logo mode. Obviously the phone does not turn on and I can not use it in the download mode because it does not enter or use odin. So I have no idea what to do with it. I was just installing an app, it turned off and from that moment on forever it seems. What do you suggest to do? Thank you. :fingers-crossed:
