Hey guys !
So since i messed up with the recovery mode, i'm stucked in the fastboot with no Download mode (recovery doesnt work neither).
So after searching 3 days in the internet i found the acces to fast through adb by puting a new laf.img in order to restore the download mode and flash a stock firmware !
My problem is that when i try to enter the command on the cmd, i get severals errors, take a look :
Code:
C:\Program Files (x86)\Minimal ADB and Fastboot>adb devices
adb server is out of date. killing...
* daemon started successfully *
List of devices attached
C:\Program Files (x86)\Minimal ADB and Fastboot>adb shell
error: device not found
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot erase laf
erasing 'laf'...

)

C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot flash laf laf.img
target reported max download size of 2147483648 bytes
sending 'laf' (18432 KB)...
OKAY [ 0.581s]
writing 'laf'...
FAILED (remote: flash write failure)
finished. total time: 5.615s
Also command : "fastboot boot laf.img" result to "Failed(remote: dtb not found) instead of flash write failure..
Of course i have my G3 855 32GB in download mode (but it goes into fastmode), so when i try a command, lines are added in the screen etc..
Does that mean that my laf.img don't work? I assumed that so i try several, but does it have to be the exact same one as the one who was in my phone before( v20a if i record correctly ) or could it be from any 855 32GB version ?
I also thought it could be a recognition problem as when i type "adb devices" or "adb shell" nothing is found..
If someone has any clue or a link to some guide i'll be more than joyful, thanks in advance !
Try adb fastboot when writing command hope it helps

Hey thank you so much for answering !
What do you mean by that, i already download the adb/fastboot driver and launch a cmd in the directory they are at, writing "adb fastboot" has no result neither, can you be more specific please ?
cm13 recently messed up my phone in exactly the same way, no recovery and download mode would jump straght to fastboot. I followed this guide to the letter and am now back running again: http://open-freax.fr/guide-unbrick-your-lg-g3/

Well i hope my problem can be solved in a safer way, i dont like much to go on the hardware part, so I'll use it as my last hope, but thanks
Altought i think my device is recognized by fastboot in someway because it responds when i type commands in fastboot, and also when i reboot it.
But i'm getting this error :
Code:
error : command never completed
error : auto CMD12 error
error : command completed with errors
error : command timeout error
failed to send stop command
failed writing block @ 1
in the screen of my phone. Does that stand for Cyanogen mode which i was trying to put on my phone ?
I mean when you enter command in cmd use adb before any command also use cmd which one available on android sdk folder....also you can use this method if adb not workinhg properly http://forum.xda-developers.com/lg-g...-9008-t3072091

Oh ok ! Also your link is not working :s
I understand that the method can work but I think that the method i'm trying to use is really close to succeed, over my search on the internet, i saw lots of people who manage to succeed with it.
But i guess i must do something wrong. I downloaded the kdz file according to my IMEI.
Then I extracted the .dz file with LG Firmware Extract. Then I extracted the file named laf_393216.bin from the dz file. Changed his name into laf.img , put it into the fastboot directory.
Then i typed
Code:
fastboot format cache
fastboot erase laf
fastboot flash laf laf.img
in a cmd from the directory.
It all seemed to work, but then when i remove the battery and restart into download mode, it goes into fastboot after the download mode charging animation..
Also when i try to boot with fastboot boot laf.img i get the error (remote: dtb not found) on the cmd.
And ERROR: Unable to find suitable device tree for device(194/0x0001001/112/0) ERROR: getting device tree adress failed DTB offset is incorrect, kernel image does not have appended DTB)
Am I doing something wrong, should I changed more file than just laf ?

I don´t know what exactly is the problem, maybe something with your win-driver, some crashed or drifted partitions or some broken files...
I just can repeat my advice: I was in the same situation with my phone after a failed cm13 update and i was trying and reading about 2 days how to solve it - after the above mentioned method, your phone would get out of this "coma".
Maybe somebody else here in this forum could help you with your mentioned method, sorry.

Well I think i'm still under warranty, so i dont wanna touch to much on the hardware.
So do you think, if i send it back without touching anything, saying i put it on charge one night and the next morning it was like this, the warranty could work?
If they found it's rooted or they understand you did something with your software your warrenty is void ?

Remove the battery, put it, press the volume + and connect to PC USB, if like entering download, what happens to us not to go, will leave the ****ing LoGo, Well, hold down the volume + and not let go, I think it is less for 2 minutes more. After a while, the computer tells us that something was connected, the phone will tell you who is in fastboot as I said before, if not let me fastboot flash boot files and the LAF, recovery ect, nothing happens, there is still a magic command.
fastboot boot laf.img
Keep it in the ****ing heart

You have several options:
- find your phone firmware, extract recovery.img and flash it back through fastboot(do exactly the same for the LAF partition to restore download mode)
- flash a custom recovery for your phone model, if it doesn't work try an older version of TWRP, also it can be that your phone is not d855 but d850 model, so try to flash a d850 custom recovery and see if it works(that was exactly my problem and why i got stuck in fastboot mode, because my phone is d850 model and in settings it says d855, so I flashed wrong TWRP)

It seems that your phone's bootloader is locked, you can try to execute this command: "fastboot oem unlock", and then check state with "fastboot oem device-info". But some people says that it does nothing, so you can try and check for yourself.
You can also try to boot directly an image from fastboot for eaxmple:
Code:
fastboot boot laf.img
or
Code:
fastboot boot twrp.img
So if you could successfully boot a laf image you would be able to access download mode, and if you could boot a custom recowery then you could access ADB and to try to flash other partitions, or even flash a custom rom...
Can anyone offer a little assistance please?
I took delivery of my 3rd replacement G4 this afternoon and I'm trying to unlock the bootloader which hasn't been an issue on any of the past 3 devices.
First up, I managed to get the device id, get the unlock.bin from LG but couldn't get the device to respond to any fastboot commands (it was just stuck at "waiting for any device"). After an hour or so of pissing about with drivers, fastboot can now see the phone using the "fastboot devices" command, but when I attempt to flash the unlock.bin file, I receive the below -
Code:
C:\sdk-tools>fastboot flash unlock unlock.bin
target didn't report max-download-size
sending 'unlock' (1 KB)...
FAILED (command write failed (Unknown error))
finished. total time: 0.016s
It doesn't appear to respond to other fastboot commands now either. "fastboot oem device-id" returns -
Code:
FAILED (command write failed (Unknown error))
finished. total time: 5.005s
"fastboot reboot" looks to reboot the device and the on screen command prompt claims to have rebooted the phone successfully, but the phone doesn't reboot.
I've tried different cables, different ports to no avail. I could try another PC but it's in my sons room and he's asleep at the moment. Both PC's are running Windows 10.
Any other ideas?
It's an EE Branded device and according to the LG Info app, the serial number begins with 609 if that's important.
Please disregard, after uninstalling LGUP, the associated dll file and using an alternative version of fastboot (specifically the version included in this)., I've just managed to flash the unlock key and my G4 is unlocked.

hello, so after trying to flash stock lollipop something went wrong and now can't access download mode, i tried to flash laf.img but i can't flash anything using adb, plz help.
When in fastboot mode:
Code:
fastboot flash laf laf.img
doesn't work?
I've restored download mode on a V410 before that way just to see if it would work, and it was successful. I nuked my laf partition intentionally because we didn't use to have a kdz for the V410, and I thought it would be easier to recover the tablet with fastboot available than a useless (for the V410 without a kdz) download mode.

Thank you for the replie, no, every time i trie to flash something or unlock the bootloader i get this message : failed (remote: unknown command)
HI there!
After multiple problems with the custom ROMs I tested, I finally decided to go back to the stock ROM by downloading it from the official thread. I extracted the .tgz archive, run the "flash_all.bat" program, which failed by saying it failed to check the sparse CRC.
So I looked for a solution and finally commented out the line that sent the CRC files to the device at the beginning. The flashing worked fined, but after rebooting I'm now stuck in a bootloop.
I entered fastboot by holding Volume Down + Power and got into it without problem, but when I tried to flash TWRP to install something else, I got the "FAILED (remote: 'Failed to load/authenticate boot image: Load Error')" and after checking, it seems that my bootloader has been re-locked!
So I'm now stuck in fastboot, both the Global and EEA roms won't work, and I can't flash an alternative recovery.
What can I do?
Thanks in advance for your help!
EDIT: I ran the official MiFlash Unlock tool, which tells me my device is unlocked, which is really weird. The "fastboot oem device-info" command indicates: "(bootloader) Device unlocked: true".

This is a forum dedicated to the Poco F3 so I think you should ask it on the Redmi 7's forum
Use MiFlash to flash the fastboot Version of stock.

Don't flash recovery. Use this command instead:
Code:
fastboot boot recovery.img
and it will boot into recovery. Then you can install recovery ramdisk.

I didn't find an official MiFlash tool and I don't trust closed-source tools for this kind of things.

I tried that but it didn't work.
EDIT: After re-trying several times, I was finally able to make it work by booting with ArrowOS' recovery. TWRP was not accepted, but ArrowOS' one was
So I've been able to flash the Xiaomi.EU rom, I'll stick with it for now.
