[AlinTecsan]

Hi android forum members , i get an LG for my collection of androids but this device does not behave good and every time when booting LG Logo showing but after a while it have FASTBOOT int usb init and then fastboot command reboot doesn't help i tried all commands .
When plug in a charger sometimes indicate fastboot so no download mode because every usb plug indicate the fastboot
But when booting it says Settings has stopped and no reinstall no factory reset.

The LG Android is not rooted but i reconnect the battery many times no way to get rid of fastboot and Settings has stopped problem.

not sure how LG does it, but you will most likely have to flash a firmware update. this should fix your issue. also we need some more background details.....like how did this happen? did you flash something? why are you trying fastboot? remember the more details you give us, the better we can help.

also what do you mean "fastboot reboot" doesn't help? what happens? nothing? error? can you post a screenshot of your adb fastboot commands?

do you have adb and fastboot setup correctly? are you using the adb commands in the right folder? if you type "adb devices", does adb see your phone? can you post screen shots of your commands?

I had to know how to use boarddiag to reinstall the phone so the firmware extract says out of memory so what way to reinstall without download mode is?

 

[ocnbrze]

are you sure you have the right file for your phone? where did you get the "fastboot system .img"?

and as far as your "invalid sparse file format header" error you can try this:

where does it say "out of memory"? on your phone? and you are asking about how to install firmware, correct?

what is your exact model?

my model of the phone is D620R and the out of memory is when i try to install the firmware without battery and download mode

When i want to extract the firmware i get something like this

First i forced the phone to be in download mode finally using a JIG or a Boot cable

The problem is IS REFUSING TO INSTALL SOFTWARE then no progress bar of reinstall is showing

Hi. Could you post detailed photos of this cable please? I have same problem with my LG (always fastboot/no possibility to charge/won't go to download mode & etc.).
