Hello I am having problems with the LG LS 740 volt. I only want to recover the personal data on the phone. I have scoured the web trying to find a fix.
The phone will enter boot to LG screen then fastboot mode The phone will enter factory reset screen then fastboot mode will start. Download load mode will start then after a few minuted the fastboot will start. I have tried flashing a recovery.img but it fails. also a boot.img fails
I have tried LG flash tool and some others ways on the internet but they all fail..
The one that changed the fastboot loop was a twrp boot.img. This made the loop stop and show ready for a fastboot command.
Fastboot error:
writing boot
remote write flash failure
finishing total time 5sec
The error on the phone :
error command never completed
command timeout error
command completed with errors
failed writing block @ 1
ADB devices - shows nothing
fastboot devices -shows the phone
Is there any way to get the data off the phone?
Thanks
FIx it for cash
If your in the Ventura county area and you can get the data I need off Ill pay to have it extracted.

Hello, first post and fisrst tutorial here.
So here I want to show you how you can restore completely died LG p760(or his brothers p765/p768/p769) showing nothing or just LG Logo and so well known "Security Error", or boot loop problems.
The goal is to flash stock recovery, x-loader and u-boot and to unlock the bootloader(u-boot), so it can boot Clockworkmod or TWRP recovery.
First of all you'll need a computer(preferably Win7/8), an died phone , some drivers on the computer and fastboot on the phone. Let's start.
I'm not responsible for any damage to your device made during this guide. You can continue at YOUR OWN RISK.
Please READ IT before taking any actions on your phone!
1. Get fastboot on the phone. How? You can see here and here, or search the internet. There is a driver package, install them following the instructions.
2. After you inserted phone, installed drivers, etc. start the fastboot loader script(I prefer Lelus's one, i'ts more option-rich), and select one option for ICS x-loader and u-boot for your phone. Follow the instructions, it may take 2 or 3 tries before the drivers are correctly installed. Start again if the drivers are not correctly installed.
3. Copy the bin folder that is inside the fastboot files folder in C:, press winkey+R, type cmd and press OK.
Then copy everything from v20c_00 folder inside the C:\bin\ folder, it's in attachments in the end.
Here is the time to say that this files are for p760 only, you can find x-loader, u-boot and stock recovery for you model from internet, or here in the forums. I flashed also the boot.img, but don't think it's necessary for the completion of the process. You can also extract the .img files from stock .KDZ rom with this tool here, thanks to user kuma82. In the archive is the tutorial how to make x-loader.img, it's easy.
Let's continue.
Type in:
Code:
cd C:\bin
Check if the phone is in fastboot mode with this command:
Code:
fastboot devices
It must show something like:
Code:
1234567890 fastboot
If not, check that you are in the correct folder(C:\bin\), go and check drivers(no yellow marks or unknown devices), read the instructions again.
Then after you copied the files from archive, or files that you extracted from your stock rom, type in, or copy and paste into the cmd window:
Code:
fastboot erase x-loader
fastboot erase u-boot
fastboot erase boot
fastboot erase recovery
fastboot flash x-loader 0-x-loader.img
fastboot flash u-boot 1-u-boot.img
fastboot flash boot 2-boot.img
fastboot flash recovery 3-recovery.img
You must be fast, because after 30-60 seconds(don't know exactly) of inactivity, the phone will exit the service mode it is in and try to boot. Nothing bad happened, just load fastboot again and repeat the above fastboot commands.
After all the commands are completed without any errors, plug out usb, plug out battery, put the battery in, start the phone. The "Security Error" message MUST be gone. If it's not, probably your recovery is wrong, flash recovery again, if not, try with other recovery. This is working on P760, at least on mine. Here the S/W Update mode must also work like a charm, and you can try with some KDZ updaters, but that's not for this tutorial.
4. Now for step 4 we will need the phone in Recovery Mode. With phone turned off and battery inserted, press VOL_UP+HOME+POWER, when LG logo shows, release POWER and hold other two while the LG Recovery Mode show up. The phone must go straight into recovery, not bootlooping or showing "Security Error". If this happens, probably you recovery or u-boot is wrong.
Now put the usb into the phone and install the drivers from usb_drv_windows folder that is in the fastboot archive.
5. Type into cmd window:
Code:
adb devices
It must show something like:
Code:
1234567890 recovery
If not, you know..
Then we will unlock the bootloader with this command:
Code:
adb oem-unlock
The phone will restart, don't touch nothing. You'll see screen with info on what to do. Guess what..? We must press the VOL_UP button to confirm that we want to UNLOCK the bootloader, so it can load unsigned recoveries like CWM or TWRP and not to show the annoying "Security Error".
6. The phone will go into fastboot mode itself, you must install the drivers, again from the folder in the archive.
Now we'll flash CWM recovery with the help of fastboot. Copy the recovery-clockwork-6.0.2.9-p760 or recovery that is for your model to C:\bin\ folder.
Write:
Code:
fastboot flash recovery recovery-clockwork-6.0.2.9-p760.img
fastboot reboot
The phone will reboot, and hopefully you will not see "Security Error" error message. Now try to boot into recovery - pull the battery out, the usb cable, put battery in, and hold down VOL_UP+HOME+POWER, you know..
7. If everything is successfull you phone will load the recovery and you will be able to load nandroid backup or stock update.zip or CyanogenMod on your phone. Don't forget to wipe cache/data and dalvik's cache. From here you can backup your data or do whatever you want.
If your phone is not totally bricked, and if you are lucky enough you can continue from step 4(if you have recovery in your phone and it's still loading).

hello guys. some time ago I successfully installed cm13 on my g2 mini. later I tried to flash some other recovery on top, and I didn't have usb debugging enabled (most probably, can't remember for sure.) so i ended up bricking up the phone. i think it's bricked, though i'm not sure about that. if i try to boot it up, cyanogenmod logo just keeps on blinking forever, and the phone doesn't boot. i can easily get into download mode, but my computer doesn't recognize the phone, no matter which drivers i have installed. i tried all the possible suggestions that i have found on internet, no luck. can't boot into recovery, just the download mode. any help? appreciate!
EDIT: recently i did steps provided in this video: (unable to post link, because i'm a new user here, video is called "RECOVER LG L90 and G2mini bricked (CELL NO LIGA)" on youtube, if any of you have time to watch it) , which resulted in phone booting up with this
[870] fastboot_init()
[970] USB init ept @ 0x1001d000
[990] udc_start()
[990] -- reset --
[2000] -- portchange --
and so on.. when i type in terminal on my computer fastboot getvar unlocked, it says NO. if i try some other fastboot commands, it says FAILED (remote: unknown command).
any one of you know how could i fix this? appreciate any help!
up
did you try the EDL mode?
the edl mode is unavailable. "fastboot devices" is the only fastboot command that works, any other like flash or boot, starts and then just fails with "FAILED (remote: unknown command)".
same problem here

I've a similar problem: I've a bricked my LG G2 mini D620 yesterday: during the flash with LG flash tool (I wanted to go from KK stock v10j to LP stock v20d) the connection between cellular and PC was lost and after that the cellular start only in fastboot modality (no enter to download mode or other). The screen present these lines:
fastboot_init()
USB init ept @ 0x1001d000
udc_start()
--reset--
--portchange--
fastboot: processing commands
If I connect it to PC the cell respond to fastboot commands but if I try for example to erase or flash every files (example: fastboot flash laf laf.img) return "FAILED (remote: unknown command)"
It is necessary to send it to support assistance or there are other solutions? :crying:
Device: Nokia 3.2
Os: Android 10
So I accidentally flash boot without backups or anything to recover, so when I boot up my device it show up TWRP and I turned it off for like a whole day and turned it back up again it stuck on fastboot mode and I can't exit it, I tried to go to recovery mode, reboot, turned it off for a while. Then I tried flashing it with Qfil but the tool can't even detect device, I installed the drivers and still it "No port available" , and I tried to manually flash it with fastboot and after that I tried this command fastboot -w flashall , again no luck, it said that "fastboot: error: ANDROID_PRODUCT_OUT not set", and I can't do much with this phone that has no images and I don't know much stuff because I'm new to this, so anyone have an idea how to fix this, thanks.
After doing a flash for new pixel experience PixelExperience_Plus_beryllium-11.0-20210823-0645-OFFICIAL, phone restarted and then no other option for access. Boots into twrp logo and stuck.

When I do bootloader into fast boot,
fastboot devices shows
??????? fast boot
then disconnects. (after this it doesnt progress any further and disconnects from pc).

Use the latest Official TWRP since the one you have now is outdated and do clean install according the guide at POCO F1 Ultimate Collection & Guides. (You need to format data not just wipe) You can find everything you need there.
first time i turned on phone today, i was able to to do command fastboot devices and it actually showed the device id, then when i tried to flash it stopped and then everytime i connect it wont even show fastboot devices without showing ???????? and shutting down again.
ive tried installing uninstalling the drivers and boot loader drivers, i believe its something to do with that, otherwise it has unlock symbol when it gets stuck on twrp logo, then when i put into fastboot it doesnt have unlock symbol before fastboot splash, what could it be? (im unable to flash anything without getting
1. running fastboot flash/boot/ any command really
Sending 'recovery' (1551913 KB) FAILED (Write to device failed (Unknown error))
fastboot: error: Command failed
2. running command then connecting phone already in fastboot
< waiting for any device >
FAILED (Write to device failed (Unknown error))
fastboot: error: Command failed

Check AMD Ryzen Fastboot Fix at the thread I posted above. If you have Intel system just install the Fastboot Drivers which is there (at the thread) and check.
Hello I am trying to boot my phone to recovery mode to do a factory reset since it keeps restarting and it does not passes the Logo screen, it is stuck on a looping state. I tried to access the recovery mode usign the volume buttons but is not working, it keeps restarting. I did not enable debugging usb since I never knew I was going to need it. Any help will be greatly appreciated.
lol easy.
if your has problem, can you boot your phone into fastboot, don't request usb debbuging.
install this file and unzip it on your pc. https://dl.google.com/android/repository/platform-tools-latest-windows.zip
now open this folder and open cmd window inside it.
and run this command "fastboot continue" for continue normal booting.
if you need to reset your phone, can you use this command "fastboot -w"
Thanks,
I've tried that but is says command not allow.
C:\adb\platform-tools>fastboot continue
Resuming boot FAILED (remote: 'Command not allowed')
fastboot: error: Command failed
Then I tried fastboot reboot to fastboot and it gave me this
C:\Users\Aiven>fastboot reboot fastboot
Rebooting into fastboot OKAY [ 0.001s]
< waiting for any device >
fastboot: error: Failed to boot into userspace fastboot; one or more components might be unbootable.
it goes back to the looping stage again.
