[Q] fastboot flash system system.img FAILED <remote: Permission denied>, need fix
Hey,
I have a ZE551ML and want to install CM. I am following the guide here. I have run into a problem on the first step which points to the guide here. At step 7 of this guide it has me use the command: fastboot flash system system.img. This fails with the error in the title of this post: FAILED <remote: Permission denied>. I have been googling this and no one has a concrete solution. Currently my phone will not even boot as the three fastboot commands before this one worked just fine and replaced the files. Any help would be greatly appreciated!
Cheers,
Eric.
Even though it'll say permission denied, flashing recovery WILL work. From there you can either flash a custom ROM (from twrp) or reflash stock firmware (through stock recovery).
That's the only fix I've found. To flash a usable ROM and boot into it. May need to turn on USB debugging in dev options. But after doing those two things, fastboot will stop with the permission denied issues.
Hey, thanks for the quick reply.
Currently the phone does not boot at all.
What do you mean by flashing recovery?
When I enter recovery mode at the moment it says applying update and then gives me the android on its side with the red triangle and error! below it.
So i can't currently flash though recovery mode as far as I can tell.

Found a guide here dealing with this error, working on it.
Hey,
So I got my phone unbricked by flashing the recovery with the stock ASUS firmware "ASUS ZenFone 2=ZE551ML(Z00AD/Z00ADA/Z00ADB/Z00ADC) software Image: V2.19.40.22 for WW SKU only" available at the ASUS official website and following a guide at an outside link that I can't post.
Now, I have enabled developer mode and turned on USB debugging but am now getting the permission denied on all fastboot commands of the OTA guide, step 7.
Does anyone know a good next step?
Hey, managed to root the phone with: Temporary CWM
After setting USB debug on did you connect the phone to PC via USB and authenticated the PC? When you connect the phone to PC via USB with debugging on, it should pop up a window on the phone after a few seconds asking you for permission for the PC. You can checkmark the box that says always trust this computer's RSA fingerprints or something along those lines.
Hope this helps!

Yes, I did do this but I have now checked the check mark to make it always trust my computer. I then booted into fastboot but still get permission denied despite having root through CWM and having this checked off.
When I got root through CWM by the fastboot tethered recovery it gave me permission denied on all steps but it still booted into CWM recovery. I was then able to install SuperSU to root it, though it gave me an error, and I used Root Checkerr to see if the phone was rooted. It says it is but I am still unable to flash any images onto the phone since I re-installed the stock firmware.
I'm super confused about this whole thing, IDK what to do now.
Flash stock recovery again and adb sideload the stock firmware all over.
This is the latest up-to-date 2.20.40.59 firmware: http://dlcdnet.asus.com/pub/ASUS/ZenFone/ZE551ML/UL-Z00A-WW-2.20.40.59-user.zip
If that doesn't work then idk. You can Google the permission denied errors for fastboot like I did and there are various possible problems/solutions.
So, none of this is working.
I installed the latest firmware as you suggested and got root again by using Temporary CWM. However despite anything I try (been googling for hours with little help found) I cannot get the phone to let me flash anything I always get the permission denied error.

You can still flash recovery via fastboot even though it'll say permission denied it works. That's all you really need to do as you can install stock firmware via stock recovery or flash ROMs and whatever else through twrp recovery.

How can i tell if twrp recovery is successfully installed?
Hey, took a few days to cool off.
So it does seem I can replace recovery even though it says permission denied. I do this by using fastboot to flash the recovery, then from the bootloader on the phone I select restart bootloader and then when the bootloader re-appears I enter recovery mode ( I do this to prevent the possible replacing of the custom recovery by the stock OS). However recovery mode never boots when the latest twrp recovery is on the phone, I just end up back in the bootloader. When I flash the stock recovery back on this method successfully enters recovery mode. This also occurs if I just directly enter recovery mode after flashing twrp recovery.
Any thoughts?

Same here. I'm using elevated cmd, and fastboot is recognizing my device. But I can't flash anything, can't erase cahce, can't reformat partitions. Always failed due to permissions. And I'm stuck in a bootloop, and can't get to recovery (it just goes back into the bootloop when I try). Literally the only avenue I have to interact with this phone is fastboot, and I can't do anything with it.
Was updating my phone tonight and saw that it was recommended that I update TWRP first.
I did what I thought was a manual update of TWRP which turned out to be flashing the TWRP image to the bootloader and the recovery. Dumb mistake but oh well. Now my phone will boot up into the boot menu (reboot/boot to bootloader / download mode / recovery mode / power down). When I boot into bootloader or recovery, the phone simply reboots to the same menu. When I reboot to download mode, it takes me to another similar menu.
Although my computer recognizes some kind of connection from the phone, I have be unsuccessful in getting ADB to recognize my device.
I have tried downloading the stock RUU (http://www.htc.com/us/support/rom-downloads.html) but I am having trouble running the .exe. At times it says my phone's battery is too low to continue, and other times it simply says USB cable error. I have tried multiple cables and different computers.
Any Suggestions?
I ended up trying a few different combinations of RUU and USB cable, eventually one worked and I was able to factory reset back to the original rom.
Thanks for anybody who came in here to take a look

My HTC One M9 no enter recovery and bootloader only show battery and bootloop and I can't flash via recovery or bootloader or RUU, so my question is if exist the tool to flash something to sdcard with Win32DiskImager.exe + debrick.img to boot from sdcard so I made this before with samsung SGH-I747 that recover to the live that phone
Edit: I somehow could reach to fastboot mode and flashed laf.img to recover download mode but I get a boot certification verify error. I can access the phone and recovery but cant access download mode.
I decided to upgrade to MM from LP using kdz method. However I could not boot into download mode with any method. The phones just reboots normally. I tried hard button(volume up and connecting to pc), I tried adb reboot bootloader, I tried to reboot to bootloader from twrp and none of them worked. In every method I used the phone just reboots normally.
I have root + twrp with stock 5.0 rom. Any help appreciated, thanks!
I have an Asus Zenfone 2 Z00AD (ZE551ML). I tried to unlock the bootloader, which turned out to be a disaster as when the bat file said "All done", I wasn't able to get any input or display from the device. However, my computer was able to "Recognize" it by playing "Device plugged in" sound and then "Device plugged off" sound (I guess the device was still functional?). I tried to un-brick it using the xFSTK download tool and the ASUS Flash Tool, which again yielded the same result being the phone's not responding but still being recognized. I managed to get it into OS (with the boot animation thing) but I noticed that whenever i went to the bootloader and restart into recovery mode, the device shows the "ASUS" logo, then flashes and then it continues to boot into OS, not the recovery. I've tried flashing the recovery through fastboot but that didn't work as well. I don't even know what to do right now. Does anyone here know how to fix it? I need to get the device functional as soon as possible.
Try to flash custom recovery in fastboot mode
(If your bootloader is unlocked)
You have not lost your recovery partition, you only haven’t a recovery image properly installed. You have to flash a recovery (fastboot flash recovery.img) suitable for your os configuration (which is compatible with the boot loader version, divided in Lollipop and Marshmallow).
You can find here the latest TWRP.
After trying install TWRP via Download Mode android and get bootlops and freeze on Samsung logo, I found something but I need help.
I achieved install TWRP vía Bootloader mode using adb command "adb reboot bootloader" and flash twrp with odin, but i didnt install "no-encryption", "rmm" files before reboot to system, so i lost twrp.
I tried this method again but it frooze at samsung logo.
I would like know why i could do it with bootloader Mode but i couldnt do the same with "normal" download mode.
And i need help to achieve install twrp again...
