help - fastboot reason: flash failure

hi, i have a problem:
i tried to unlock my boot loader and instal a recovery (specifically the PhilZ Touch Advanced CWM Recovery), apparently the unlock did't work, i did not see that and i proceeded to install the recovery, the device reboot on the AP fastboot flash mode and says:
Device is LOCKED. Status Code 0
Battery OK
Connect USB
Data Cable
Fastboot Reason Flash Failure
now when always i press the button on, the device boot on the AP fastboot flash mode.
I can boot normally acceding to the boot menu pressing the 3 side buttons (+/- on) , but i want to solve that problem because i really want to unlock the boot loader
help please and thanks
(sorry for my english)
How did you try to unlock your bootloader?
Sent from my ATRIX HD using XDA Free mobile app
First off, would you kindly give us more information? We need to know what method you used to unlock your bootloader, your operating system, and your phone's original carrier to fully assist you. As it stands, you best bet is to ensure you have to correct drivers for adb and fastboot, then use RSDlite or Mythtools to flash the correct fastboot file to your phone.
I use the motopocalypse method for unlock the bootloader (but apparently didn't work), i have jelly bean and orignally is from nextel (mexican carrier) but a change it to telcel (also mexican)
Have you tried reflashing the stock jb Mexican sbf files? You can find them in the help and troubleshooting section.
there is no problem if i try to flash it when i have the bootloader locked?
You can flash stock roms even when bootloader is locked....

Tthanks for the help
another problem
now i tried to unlock the boot loader but before the process start, in the console appears the message "TrustZone Write Failed -11"
exist a solution for that?

I try install CyanogenMod but dont know bootloader lock...

Hello Friends ! I tried to install CyanogenMod for Atrix HD, but I forgot to unlock the Bootloader and now my phone shows me the message FASTBOOT can not load the Boot. Someone can help me with this problem to retrieve my phone ? Thank you very much for the prompt help from everyone .
Reinitialize fastboot and rsdlite to stock and start over again with unlocking BL and rooting the phone by flashing a recovery.

My Huawei P9 is stuck in bootloop i think?

Hi, i have tried to remove my root and unlocked bootloader as I didnt think they were correctly installed in the first place. Also I wanted to install a new oem update that it keep reminding me of in the background. So now after doing alot of things found in forums and youtube I have come to an end point were the phone just comes to the bootscreen, "your devise has been unlocked and cant be trusted." from here it is just stuck with the "your devise is now booting..." then nothing happens so I realy need help now, otherwise I will have to buy a new phone within the next days.. I cant still get into the twrp and format/wipe data etc, so is it something in here I need to fix then?
Anyone that can please help me out a bit?
Regards Kristoffer
I'm having the same issue. I am unable to flash a custom rom or an official rom. One issue I am having is that I can not relock the bootloader as I get an command not allowed. Please can someone help with this issue.
Thanks

But I cant get into the twrp anymore, only the fastboot and recue mode and the huawei erecovery mode, and in this the wifi just gives me failed to download the package or something like that.... ://
I managed to get in recovery by running the oem unlock. The problem I have is that I am unable to lock the bootloader again.
I really want to get the phone working again. I don't want to have to send the device to a Huawei Service Centre since the bootloader has been unlocked.
I really hope someone can help us all get the device back to stock firmware.
Thanks
How did you get to the recovery mode? I cant get to the twrp anymore, i think i did something wrong and wiped data or formated it so now i can only se bootup screen, or huawei logo or get to fastboot and rescue mode. There it says phone unlocked and frp (or something) in green letters lock....? And also the huawei erecovery which i cant do anything in...
I run fastboot oem unlock and flashed twrp using fastboot.
I have managed to flash update.app, Default_hw.app, Default_normal.app and Default_eu.app using an app called DC Phoenix, but now when the phone boots it goes in to eRecovery and the touchscreen doesn't work. Even when I flash twrp again the touchscreen still doesn't work.
Please can someone advise what to do to get the touchscreen and the other phone back to normal.
Thanks

what android version was before, what android wersion you tried to instal, what recovery you used. ?
oh, but if fastboot isnt working, you more or less are done. if im correct, even dc phoenix use fastboot..
"Step 1
Write compatible UPDATE.APP file in fastboot with DC Phoenix"

i can't remember the version but im sure it all arounds in 2.1...something

Stuck on bootloop

Hi everyone!
Since yesterday i am having problems with my phone, first it briked after a normal update, thanks god i unlocked the fastboot before, i installed a custom OS but didn't liked it, so i wiped both partition (and i think i ****ed up there)
So now i can still enter fastboot mode, but everytime i try to send fastboot boot judypn_TWRP_bootable-metadata.img (that yesterday worked) not it's not working anymore, it just boots normally and remain stuck in bootloop
On my microsd i put the img of twrp with metadata HavocOS and twrp zip too, yesterday i could install and enter in recovery mode them without any problem, today the boot img is sent but the phone "ignores" it.
PS. I can enter fastboot mode without problem, download mode isn't working
Thanks to anyone who can help!

So first, the forum you posted this in is called 'Roms, Kernels, recoveries and other development'... so which 'development' is this? a Rom? a Kernel? a Recovery?
None of the above right? So what you have is a 'question', and it should be in 'Questions and Answers'. Sorry if that offends, but if someone wants to find something in these forums, then posts need to be in the appropriate places...
First thing I'd do would be to get the phone's download mode (lgup) working again and flash a stock kdz. That way you can basically 'start over' (and hopefully have better results with your endeavors).
try this initially: Follow this link and read the 'notes' file. Hopefully that will give you lgup, if it doesn't then it's a more involved process to use edl and flash, basically, a whole image.
cheers
