"It seems possible ...

WARNING! - Refurbished only means you will get a working phone back.

Even if they guarantee to return it with your data intact, be VERY CAREFUL! they are just telephone call handlers and do not know for sure what will happen, also people do not tick all the correct boxes and others do not look at all the boxes, so you could loose out those ways!

I am very surprised that there is no information on this subject.

It must have been an issue for 1000's of people over the past few years.

My problem is that ""back up has stopped"", would not re-install, and I could not find out why (it said memory, but there was loads free - since found it was talking about Dalvik).

Over the weeks I built up a collection of useful information and photos which I do not want to loose.

I am assuming yours is an Android phone, but even if it's a Windows phone, the principle is still probably the same.

It appears to be possible to recover files from the internal memory of a dead phone using a PC, free software and USB cable.

The principle is start the Flashing process, BUT do not Flash the phone, because I can not be sure it would not destroy your data / files.

When at the stage to be able to Flash the phone, effectively your PC thinks it is communicating have a ""USB memory device"".

This is achieved by removing the phones USB driver and substituting another driver (to enable the Flashing process).

I've not had the time to spend on it that I need.

I will come back when I do finish ...

BUT do not wait for me, there seems to be too many things going wrong, and the most important get done first. Which is why I have things waiting for over 1 year now.

One problem I have is that Windows keeps throwing out the ""substitution USB driver"" and replacing it with the original phone USB driver.

Windows thinks the phones driver is more suitable, so automatically re-installs it.

I know the issue, I've had it several times previously with the ""unknown device USB driver"" (a crash causes the driver change). I just need to find the ""Windows stored back up driver"", delete it, then Windows will happily accept the ""substitution driver"".

Ahhh, the joys of owning a MS Windows computer :-(

Some usefull software names :-

USB VCOM Driver

Windows drivers - A25_USB_VCOM_Drivers

usbdeview_droidtricks

Some useful search terms :-

brick

unbrick

flash rom

SP Flash Tool exe v3 (not to use, but the process' before is what's wanted).

Searches with search engines (Google, Yahoo, etc.), also You Tube (I could only find Flashing, but as previously, it's the process up to the ""Flashing point"" that you are interested in).

Sorry it's unfinished information, but at least it gives you hope and some where to start.

Data Recovery firms will be able to recovery the data / files and some are open to ""please help, I'm skint ..."", by reducing their prices to a poor private person, but they will not do it for free.

So good luck to all of us."

The best cybersecurity firm of 2018 for me is the rootgatehacks organization, they provide the best services from cooperate espionage to cheating spouse investigation. Their tech updates are the best and they can also protect you from spyware and malware only for the purpose of stealing information from you, i have gotten alot done with the help of this organization. You can search them on google if you want more information

"HERE IS THE FIX WITHOUT LOOSING YOUR PRECIOUS MEMORIES!!!!

This is the second time my girlfriends phone has had the bootloop problem. So here is the fix to boot it up and get a chanch to save your important data before factory reset! Take out the battery then reinsert it but dont turn it on! Put your phone in the freeze for about 15 min. Then take it out and it should boot up normally. If not, put it back in the freezer just a bit longer, like maybe 5 min then try rebooting it again. Now if the phone gets warm enough it will go back into its bootlooping problem so move the phone from the freezer to the refrigerator along with a usb cable sticking out when you close the door. Hook up your usb cable and start transferring your data. After your data is saved, perform the factoy reset by taking out the battery, reinserting the batery, hold the volume down button then hold the power button. As soon as you see the LG logo release the power button then quickly hold it again. Shortly you will see the factory reset option. Select yes to clear all its memory and get you phone working in its factory settings. Here is the article that gave me the solution the first time this happened http://forum.xda-developers.com/tmobile-..."
