Help with possible brick! - LG Optimus L90

So I was trying to unlock my bootloader with LG Laf Recovery MultiTool v1.2 (You can find it on android fourms) I choose Automatic unlock, and it went through fine. Until it got to the fastboot location. When it tried to use a command it returned: FAILED (remote: unknown command). Now its stuck booting into fastboot, but it won't accept any commands. They all return with the above error. Is there anyway that i can fix this?

What is your phone model? Can you enter download mode? If yes, then you can flash stock kdz ROM with LG Flash tool, see tutorial about returning to stock. Good luck.

[SOLVED] [Q] HTC One Doesn't boot, Can't Get Into Bootloader, only Fastboot

Hi guys,
I've searched the entire web (including all the XDA links regarding the HTC One), tried every solution out there and still can't fix my problem. I don't know where else to turn, so I am creating a new thread in XDA Developers.
Originally, I had unlocked my bootloader and rooted the phone to use stock android. A couple days ago, I tried to re-lock the bootloader and change back to the original Sense UI; however, when I did this, I got stuck in a boot loop (the phone kept rebooting and didn't boot into the OS).
I then went back into fastboot and restored all the files and settings.
Now, the only things I can actually go into is fastboot and bootloader (cannot boot into OS or even see the boot screen). The only way the phone can connect to my PC is if I'm in fastboot. When I go into bootloader, the phone disconnects from my PC.
My phone is from Telus in Canada and I can find a couple .zip RUU files on the web for Telus, however when I try to flash the phone using the command "fastboot flash zip filename.zip", I get the error "signature verify fail."
When I tried to use the RUU.exe from BrightStar (developer version), the update failed and there was a message saying to download the original firmware.
The last thing I tried was the command "fastboot oem rebootRUU" (I did this to change the CID and MID, so I could use the Google Play RUU). When I do this, it goes to a black boot screen that has the HTC logo in grey (this is the boot screen I got from trying to use the BrightStar RUU.exe. It was originally a white screen with the HTC logo in green.). When I'm at this screen, I can communicate with the phone using fastboot commands, however when I try to change the CID, I get the error: "status read failed (too many links)," and when I try to change the MID, I get the error: "Command error !!!"
Just to remind you guys, I can only communicate with the phone using fastboot commands. No adb.
I have officially given up and gone crazy! Please Help!!!
*UPDATE* - Sorry, forgot to mention that I've idiotically re-locked the bootloader. Unlocking the bootloader would probably get rid of the "signature verify fail" message. I'm unable to flash the recovery because the bootloader is locked and I can't get into the filesystem because the phone needs to go into the OS for that.
When I try to unlock the bootlader by using "fastboot flash unlocktoken Unlock_code.bin" it gives me the error: "cannot open 'Unlock_code.bin'."
I need to be able to access and make changes to the file system by using fastboot commands and I have no idea how to do this.
*UPDATE #2* - I've managed to re-unlock the bootlader (I didn't have the Unlock_code.bin file in the same directory as the current directory in my cmd window). I've re-flashed the recovery successfully. Now when I reboot, it goes into recovery mode (still can't boot into the OS). I'm using ClockWorks for the recovery.
Now I'm unable to root the phone. I'm trying to write SuperSU v1.65 to the phone by using the command: "fastboot flash zip UPDATE-SuperSU-v1.65.zp" and I get the error message: "remote: not allowed."
I can flash the recovery.img and boot.img (can't flash system.img because there's "not enough space"), but I can't flash .zip files
When I try flashing another boot.img, I still get the same thing. The phone goes to the boot screen and can't boot. Then, it reboots and goes automatically into recovery (I can still get into the bootloader and recovery).
Any suggestions to get past these permissions?

I'm sorry, but I'm kind of a noob. How exactly do I re-flash a recovery. do I do this using the command: "fastboot flash recovery recovery.img" or should I try "fastboot flash zip filname.zip" (RUU.zip) again?
*UPDATE* - I've tried erasing the cache and re-flashing the recovery and I still get the error message: "signature verify fail."
I'm still waiting for someone to help me. Is anyone going to help me fix my problem or is my HTC One doomed?
If you are on Telus
Download http://www.htc1guru.com/dld/ruu-zip...157-04_release_336571_signed_2_decrypted-zip/
Relock your bootloader
Then
fastboot oem rebootRUU
fastboot flash zip RUU_ZIP_M7_UL_JB43_SENSE50_MR_TELUS_WWE_3.22.661.1_R3_Radio_4A.20.3263.16_10.38k.1157.04_release_336571_signed_2_decrypted.zip
May have to run the flash zip command twice..

I've already tried that. When the bootloader is locked, I get the error: "signature verify fail."
OK.. Unlock bootloader, flash custom recovery, adb push this file: http://www.htc1guru.com/2013/11/guru-reset-3-22-661-1/, and install it from recovery.

I can't use adb commands...
I have all kinds of USB drivers installed (including the one from SDK Manager). When I type in the command "adb devices", I get nothing.

adb commands will work if your in twrp recovery
and the reason your ruu.zip failed is because you were not in fastboot oem rebootRUU when you tried them, seems you mixing and matching different forums of flashing .. it don't work like that.
Just to re-iterate..
1. fastboot oem rebootRUU (this will show a gray HTC logo on black screen)
2. fastboot flash zip RUU_ZIP_M7_UL_JB43_SENSE50_MR_TELUS_WWE_3.22.661.1 _R3_Radio_4A.20.3263.16_10.38k.1157.04_release_336 571_signed_2_decrypted.zip
May have to run #2 again if it shows flush error..

I Installed TWRP and went into the TWRP recovery and noticed the adb commands work.
That file didn't work, however the Guru file you mentioned earlier did (with the "adb push" command)! Thanks so much for your help! Everything is working perfectly again!
Thanks for posting back. Edit your title to [SOLVED]! and enjoy!

stuck in fastboot, cant flash anything, cant go to recovery

my phone: Nexus 6 32gb international
marshmallow (MRA58R) with cataclysm rom
twrp custom recovery and elementalx kernel
rooted, unlocked bootloader, no xposed
1. my phone was running fine until it randomly crashed and got stuck in fastboot menu. trying to start does nothing but in bootloader logs it shows this:
Code:
failed to validate boot image ret=-1
trying to reboot recovery gives:
Code:
failed to validate recovery image ret=-1
so i guess time to flash a MRA58R factory image right? however:
2. trying to flash via "flash all" script, manual one by one flash, or using the nexus root toolkit gives:
Code:
<bootloader> failed to flash partition
FAILED <remote failure>
this happens when i try to flash recovery (Stock or twrp) or bootloader or bootimage or system or anything. i have to my knowledge adequate platform tools setup which ive used multiple times before. my sdk tools are updated as well. at this point ill try anything. and i use windows. please help

Is the phone unlocked?
Code:
fastboot oem unlock
Can you erase userdata and cache
Code:
fastboot -w

the phone is unlocked. it shows unlocked status 3 or something. and no -w gives the same error (failed to flash partition).
i was wondering i dont remember if i had "allow oem unlocking" enabled in the dev options and now i cant access it. is there a way that can be a problem?

I doubt it, since you don't need to unlock it a little more.
You should check your USB cable, or try to switch to another port. But if the error still persists, you need to send it to repair.
I am sorry mate, but u might have to send it in for real
Maybe your nand memory is corrupted. Since ur phone just crashed for "no reason" and then got stuck in fastboot, it may be an indicator for that.
Best regards!

I BELIEVE once you tick it and unlock, it does not turn back off (allow OEM unlock)
But as said above, this option only allows the bootloader to accept the unlock command...
Best case is the internal storage got scrambled and your partitions/ partition table is corrupt/missing/gone, worse case and maybe more likely is hardware failure?
Not sure if you can send terminal commands, but next step is either just RMA or searching the internet for a way to manually rebuild partition table from bootloader?
I guess?
Sounds like it messed it self up pretty good somehow, sorry man.

Unable to flash custom recovery, lost Download Mode

I have been trying to get the new Cyanogenmod 13 on my LG L90 d415, but have had no success. At first, I was able to use Flashify to flash the latest TWRP for the l90. I forgot to backup my stock recovery. I was able to wipe my phone, but every rom I tried flashing said "invalid zip". I tried different versions of TWRP and other recoveries such as Clockworkmod, but now I can't get into recovery at all. With every recovery I try to flash, when I reboot, the phone shows the LG logo and at the top left, it says:
[340] fastboot_init()
[440]USB init ept @ 0xffc100
[460] udc_start()
It freezes there, I have to pull the battery to reboot. I read on another thread that the bootloader needed to be unlocked. People said the d415 already had an unlocked bootloader, but I tried to use fastboot to unlock it anyway. I followed the instructions to get fastboot (backing up laf and then zeroing it out) and was able to successfully unlock the bootloader. However, fastboot refuses to flash my laf.img backup I made. It says:
C:\adb>fastboot flash laf laf.img
sending 'laf' (22528 KB)...
FAILED (command write failed (Invalid argument))
finished. total time: 0.020s
I tried downloading an laf.img online and it gave the same result. Flashing custom recovery still gives the same result as before I unlocked the bootloader. I don't understand where I went wrong.. I followed all instructions carefully. Anybody know how to fix this? I would at least like Download Mode back, if nothing else, so I can flash a kdz and reset it.
Same problem to me
Pls help us
I am also facing that same issue
Pl. Help

One problem is your command line...
fastboot flash laf laf.img should be fastboot flash /dev/block/platform/msm_sdhc.1/by-name/laf laf.img.
Only use "laf.img" if it is in the same folder as the fastboot executable, otherwise you will need to include the full pathname to your laf.img.
If you can boot the device to Android, the same can be done with ADB commad-line or a terminal emulator app using 'dd' to write the image instead of fastboot.
EDIT: Didn't realize this thread was over a year old... LOL

[Q] fastboot oem unlock with correct code fails with "command did not succeed"

[Q] fastboot oem unlock with correct code fails with "command did not succeed"
Hi,
I recently got an xperia Z into my hands and wanted to unlock the bootloader.
I checked the IMEI in the system settings and requested and received an unlock code for the device.
I unlocked the bootloader with the code,
but now I am not able to flash or boot anything via fastboot (device still boots normally though).
When trying to flash e.g. twrp to the boot partition
(
Code:
fastboot flash boot boot.img
)
it fails with "remote: command not allowed"
Also trying
Code:
fastboot boot boot.img
does not work properly:
In this case it just reboots into Android.
I am using Linux to flash stuff.
I already tried using the flashtool, which also didnt bring me any success.
Does anyone have an idea or a solution to this problem?
Best regards
