Target didn't report max-download-size

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.

Hi, I am trying to install twrp twrp-3.1.1-0-odin.img so I can get RR rom on my C6502
first of all, I'm well aware of steps, and I personally have this rom installed in my xperia m, so it won't be hard for me to understand and it's quite easy as 123 over there
the problem I'm facing is, this xperia ZL c6502 l35h device seems to have something in different I'm not able to flash twrp here
I used repair feature in sony pc companion, done successfully, start device, wait for first boot time, configure, enable unknown source, enable usb debugging, connect cable to pc and allow RSA pc's code
power off and connect with voldown, used flash tool to unlock bootloader (yes the blootloader status unlock is yes in *#*#7378042#*#* code confi thing)
bootloader unlocked successfully, device tried to be in bootloop for three times, then it started, like first boot took somewhere 15 min to start up, and everything is fine, except I cannot increase brightness anymore but nvm
I again enable unknown source, and usb debugging, and allow my pc's RSA key > always allow
poweroff, connect in fastboot, flash kernel > select the just downloaded twrp from official source 3.1.1.0 I think
I flash receive an error says remote: command not allowed

So, I have my bootloader unlocked, I can confirm that because after booting up post unlock, there's change in system, I cannot increase brightness, and in that code *#*#7378... I see more Bands available before unlock
and device booted after like 3 bootloops automatically, what am I doing wrong, and what should I do? how are people able to get this rom in their device?
btw, I'm dealing with firmware 10.7.A.0.222 India version, all latest as per pc companion repair feature and today it will be offc latest one
and the version of my flashtool is 0.9.18.6
in minimal adb and fastboot, I tried this
fastboot.exe -i 0x0fce getvar version
result is 0.5
fastboot.exe -i 0x0fce oem unlock 0x[my key in caps]
first time it fails and second time it does, and output is successfull
then I proceed to flash twrp
fastboot flash recovery twrp.img
I receive failed command not allowed
then I try
fastboot flash boot boot.img
successful, but phone bricked
I reflash 10.7.A.0.222 and device working again, but how do I flash twrp?
what am I doing wrong?

Just to confirm that you did change your downloaded recovery name to boot.img and placed it inside c drive adb folder, right?

yes, I renamed to boot.img after googling and learning,

Hi, I just managed to get it done, but another problem arise
I flash anew 10.7.A.0.222
after that, I ticked unknown source, and enable debugging, and as people mentioned that it means bootloader is not unlocked
I fired this command five times
fastboot.exe -i 0x0fce oem unlock 0xDB29CBBEFBAB4A64
and after that I fired
fastboot flash boot boot.img
output was

Here's something more I learned
If you unlock boot loader, and restart, > tick unknown + usb debugging, and boot to bootloader, it won't let you flash boot.img
but if you immediately unlock bootloader, and without restart, you flash boot.img, it will go success
but after that, your device won't start
it's not starting, it vibrates, but no display, no matter how many times you press and hold power button to start it, it will vibrate, and won't start
I tried each and every combination of vol +/- and power button, but it's not starting that way
EDIT:
but I can still press and hold vol up and connect cable to get in fastboot mode, after which if I try flashing twrp, i again get command not allowed, except if I try fastboot.exe -i 0x0fce oem unlock 0xDB29CBBEFBAB4A64 and then fastboot flash boot boot.img
after which I will get success flashing that recovery, but device won't start

For me, i think if you're recently to unlock your bootloader. Have you try to confirmed that your bootloader really unlocked from stock firmware? (*#*#7378423#*#*) and see about bootloader info?
If bootloader already unlocked, then you're safe to flash, And have you read any requirement to flash recovery for your device? i think it's like only work for custom rom or only work for specified version of firmware?
If device won't start, then it should from kernel problem. Try to check your custom recovery compatibility before flashing, and tell us what happen next

okay,
so few points worth mentioning
1) my bootloader is unlockable, and is unlocked, I mean in 7378423 it's written yes in root status bl unlock
2) I have received code from sony, and I can unlock it
3) the only recovery that works is https://forum.xda-developers.com/showthread.php?t=2288118 that too only after using kingroot, which gives me old philz and 2.8.7.0 twrp which are not helpful, also I tried to flash RR 7.1.2 based, phone basically gets bricked
4) I can only flash twrp or any recovery if I unlock bootloader, and without restarting I flash boot.img, if I do so, phone gets bricked
Here's the ss of BL status

There's nothing written about requirements of twrp to flash, or rom, they just don't have, but as I have latest firmware, it should work, even nothing is written in linageos thread

I found basically few members of the community faced this problem

Redmi note 8 pro, bricked for ever?

Hello guys:
One month ago i bought a Redmi note 8 pro, when it comes after a long time (almost 3 weeks) it comes with bootloader opened so i couldn use for example NFC pay. I looked for information to lock the bootloader i followed steps and bootloader was closed but phone was bricked too, so only can put smarthphone in fastboot or in recovery mode. I tried flash some roms by Fastboot using CMD in pc but appears this message
C:\adb>fastboot flash system system.img
target reported max download size of 134217728 bytes
erasing 'system'...
FAILED (remote: not allowed in locked state)
finished. total time: 0.004s
that was expected because bootloader is closed, but now i dont know if its posible to unlock bootloader and flash a new rom or beeing bootloader closed, flash a new rom for unbrick the phone.
To solve this problem I heard something abou autoriced xiaomi accounts and something about waiting seven days for unlock but i dont know nothing about it.
Thank you guys.

I'm sorry for answering late, but I'm very busy with the current health situation.
What I have done is focus on unlocking the bootloader, and later will flash a new rom.
To unlock the device i have download "mi flash unlock tool"
Software recognice my phone
Click on "unlock">"unlock anyway">"unlock anyway"
Verifying device-ok
Unlocking-Fail
Couldn´t unlock
Please add your account in MIUI´s Settings > Developers option > Mi Unlock status
This way doesnt work.
I try by fastboot and cmd commands

And well...I dont know what to do now.

It won't unlock because your device is already unlocked. You need to flash stock rom from custom recovery. Install custom recovery via adb. when you go back to stock rom device will be oem locked again. Also original account that was used to oem unlock device may be required that is why it might be failing.

Huawei Y5 (DRA-LX3) Unlocking bootloader

Hi, I need some help with unlocking the bootloader of my phone [Huawei Y5 (DRA-LX3)] Please!
So, I am using the adb7fastboot method to unlock the bootloader, there are very limited options to do this process, but I've managed to find what might be the unlocker code for the command:
Code:
fastboot oem unlock xxxxxxxxxx (the unlock code)
Naturally, the warning screen appears on my phone (the one that tells you about erasing all of the data by unlocking the phone), and when I select "Yes" the phone displays an error:
unlock failed... return to fastboot in 3s
And the adb/fastboot window goes something like this:
Code:
...
(bootloader) Start unlock flow
FAILED (remote:
Unlock failed - Err:0x7
)
finished. total time: 6.137s
What do you think? Is there a solution that can save my life? Thanks by the way!

Unlock Bootloader

why always like that , i've tried to get new img but still remote invalid data

Z2 Plus doesn't actually lock the bootloader. With locked bootloader, the phone can still boot with unofficial ROMs, there's merely a warning message before the phone continue to boot - even if you unlock the bootloader, such warning still won't go away.
You may use QPST/QFIL's partition manager (with the firehose flasher program extracted from stock ROM package) to flash TWRP into the recovery partition.
Unlocking bootloader merely provides convenience in fastboot mode. However it's not hard for Z2 to enter EDL (9008) mode, the so-called "deep flash USB cable" works. There're test points on the mainboard as well.
