[Q] fastboot flash system system.img FAILED <remote: Permission denied>, need fix

[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.

Oneplus 3 Boot Loop

So I tried to flash another rom by flashing TWRP and unlocking the bootloader, which worked and I then had installed Freedom Os. Then I locked the Bootloader to get the Message away, but know when you charge it or turn it on it is in an boot loop which repeats the Oneplus Logo what you normally see, but very short and after that it bobrates turns the screen off and it atart again. Or I can go into fastboot mode, but when I try to go into the recovery, it goes into the Boot Loop again. Is there a way to get the Original OS back? Ive already dopwnloaded it but I cant get in on there. Can you tell me how to fix it on my own?

[GUIDE] Mega Unbrick Guide for A Hard Bricked OnePlus 3 > METHOD 1

If you can access fastboot mode, connect the phone to a PC, then go to ADB and erase recovery using the command " fastboot erase recovery" and install TWRP 3.0.4-1 using the command " <fastboot flash recovery <recovery.zip/img> again.
Once you do that, boot into TWRP, go to wipe and wipe everything. Once you do that, transfer the stock OOS into the internal memory using copy-paste , then go to install , select the transferred file to install the OS or else go to advance setting in TWRP and select adb sideload and use the command "adb sideload <filename.zip>".
This should install the OS on the phone.
If you want to go complete stock, then you also need to install the stock recovery. Search the forum to get the relevent files or else you can download it from the OnePlus website and later on update to latest OS via OTA.
NEVER EVER LOCK THE BOOTLOADER , IF YOU'RE USING ANY ROM OTHER THAN STOCK OS AND STOCK RECOVERY

Connect your phone to the PC and then navigate to installed folder, right click holding SHIFT key and select "Open command window here"
Inside command window type
adb devices
If all the drivers are installed properly, you should see you're device ID here.
then type
adb reboot bootloader
your phone will enter fastboot mode.
then type

again you should see you're device ID here.
then follow the instruction , i've given earlier.

So i've downloaded the software, installed the driver and typed in cmd adb devices "adb devices List of devices attached" is returned, so it seems like there is going something wrong. Is it because the Driver is installed wrong or because "target reported max download size of 440401920 bytes
sending 'recovery' (22605 KB)...
OKAY [ 0.528s]
writing 'recovery'...
FAILED (remote: Partition flashing is not allowed)
finished. total time: 0.551s"
This is returned when trying to flash. Do I have to be in fastboot mode or something else to be able to follow your instructions? In Fast Boot is written that the Device State is locked and Secure Boot is enabled. I messaged Oneplus and hope they have a solution which can just unlock the Bootloader when being in fastboot mode, so everything is fine again. I hope you can help me, but I still wanna say thank your for now

Thank you, but it dont works because i forgot to re-enable the oem modification and usb debugging in freedom os, maybe there is an option to do this without having this enabled but I didnt found it. So I wait for a helpful answer from somebody here or from Oneplus, I consider sending my smartphone to oneplus to let them repair it if I cant do it. Just saying that modding an S3, Asus transformer pad and nvidia shield is way easier.

Yeah I'm sorry I can't help you in your case. I'm just stating the fact. Sorry if I offended you.

Shouldn't it still be possible to reflash the properly signed official updates? TBH I never had such a problem and thus never had to cope with it. Same with recovery: http://oxygenos.oneplus.net.s3.amazonaws.com/recovery_op3.img Try flashing this one with fastboot. It's the official one. By flashing this one you might fix your stuff over adb sideloading the official full update zips.

Try the unbrick guide provided in the 2nd post to your query. It should definitely help. Better contact OnePlus tech2 support and they'll flash your phone for you. They're really helpful.

The MSM Software disconnects the smartphone while the process works

U cannot flash in adb while the bootloader is locked, u can not unlock the bootloader unless u can access ur OS, I am not sure y people was trying to get u to flash via fastboot the answer was provided to u in the 2nd post

^^^ This!
It's pretty much obvious fastboot flash will not work with a locked bootloader.
It's pretty obvious unlocking the bootloader will not work, while one can not access the OS.
Unbrick tool is the only option to bring it back to life, or sending it for RMA. If unbrick tool fails, try using different drivers and make sure it is connected with the stock cable (I've only tried with a Nilkin cable besides the stock one, which always failed at different stages during the process).
Not even sure drivers must be installed manually, I've never done that myself on Windows 10, as they were automatically installed (3 different's PC's, both on x86 and x64).

Which version of stock firmware did you last have? If it was 4.0.1 or earlier, then you can use
Code:
fastboot oem 4F500301
to issue a flash command even without unlocking the bootloader. If you are on that, then use that command and flash stock recovery and then flash stock zip.

Help me please :( LineageOS bricked my phone :(

Hello guys
I have a problem
Description:
I have ZUK Z2 and its great phone. I installed latest LineageOS ROM which have OTA updates and yesterday prompt a comunicate that I can update my phone so i clicked to upgrade. But then system is not launching and there is only twrp mode so it's bricked i tried to restore my phone with method described here but it did't work :/ QFIL says" Download Fail: Sahara Fail: QSahara Server Fail: Name of directory is invaid (last one I translated because it was written in my native language). I checked FAQ and i restarted my computer and phone, i changed name of directory to ZUK and it still doesn't work :/ Then I found that ulocked bootloader may be a problem so I tried to lock it but it doesn't work either :/ i wrote adb reboot bootloader and my phone runs fastboot mode but command "fastboot oem lock" don't work, it says only "waiting for device" and nothing happenes :/
Could you help me to unbrick my phone? i'm very desperate

Since you can enter the recovery mode go to mainscreen of twrp, wipe system, data, dalvik etc (but do not wipe internal storage!!!) and then install again lineage, google apps, and addon superuser (in case you want root)...
Regarding QFIL method. I have flashed twice the ZUK orginal software with unlocked bootlader and the bootlader remains unlocked also after the flash. I guess you cannot flash with QFIL and you get the Sahara notice because it is either:
+ you have installed the wrong ZUK drivers or
+ the rom folder name is too long or it is something else.
QFIL method will wipe your entire phone though. So i would try first to wipe with twrp and if it does not work then try QFIL.

I tried to flash ROMs via twrp like you wrote but still only TWRP starts and nothing else happens :/

Hi, what if I cannot get the the phone connected to CFIL? It always starts into twrp as soon as the phone is connected to the PC and it doesnt matter what buttons I keeped pressed.....

You wrote it wrong, when you try fastboot you need to use "fastboot -i 0x2b4c" otherwise it judt wont work and will always showing "waiting for device" hope you can get futher now.

Sorry, I dont got your point...

Hi
Head for zukfans.eu
Theres a thread and plenty of guides

Yes, there are guides but no one works for me so I came here for help :/ i'm desperate and i don't know what to do now :/

Are you able to boot into twrp? If yes, then wipe system, data, cache and flash rom again. If not, then boot into fastboot mode by holding down both volume button and connect your phone to PC. Once you're in the fastboot mode you have to flash recovery using the
Code:
fastboot -i 0x2b4c flash recovery <recoveryname.img>
, after flashing boot into recovery and allow for system modifications if a dialogue pops up and flash any custom rom with latest gapps (but you still need to wipe system and data) .

This worked for me on the advice of one of the users at zukfans:
Go to TWRP recovery terminal commands, and enter the following:
dd if=/dev/zero of=/dev/block/platform/soc/7464900.sdhci/by-name/misc

International 6/128GB Version - fake unlocked Bootloader?

Hi!
I´m not new into flashing mobile phones, but with my new Mi Max 3 I´m not sure to do the right things.
I bought the 6Gb/128Gb Variant (so Chinese or international Version) and the Seller (from Gearvita) sent me the Phone with unlocked Bootloader and GlobalRom. It seems to be the official Global Rom, because there are normal OTA Updates from Xiaomi and they work.
I tried to flash TWRP via fastboot mostly for enabling Camer2Api and for changing the DPI with root-access, but there is no responding from the phone while Fastboot Mode
ADB Driver are installed, Developer Options and USB-Debugging are enabled. If I start the CMD or PowerShell it recognized "adb devices" as normal and with the command "fastboot bootloader" the phone goes into Fastbootmode, but then there is no reaction anymore to any command. "fastboot devices" says "no device found" , "flash recovery .img" says nothing or sometimes it says image "size too large"
So what is the best way to get a save unlocked bootloader official from Xiaomi? Mi Unlock Tool don´t recognize my phone, too :crying:
I know I should go back to normal Chinese Rom and locked bootloader, than unlock the bootloader official way and then flash GlobalRom and install TWRP, but how to get back to CN Rom without doing any mistakes?
I´m on latest 10.3.5.0 since yesterday - I hope there is no problem with ARB in that case.
Thanks in Advance

In the meantime I checked the fastboot behavior with an older Notebook (Windows 7) and now everything is working correctly.
I had to use adb sideload in TWRP and was able to install Magisk and Camera 2 API Enabler.
But I tried soooo many Driver Setups with Windows 10 and nothing was workling as it should
I´m not sure if I have still a fake unlocked bootloader, but everything is working for me now

Interesting. I have a somewhat similar experience. Got a China phone with global rom (4/64GB variant.) The phone updated to 10.3.5.
I immediately rooted it (using TWRP boot; did not flash TWRP - with a magisk Zip) an all seemed fine.
After your post I tried to test the process again - and to my greatest surprise
1. I see the phone with fastboot devices but
2. The same TWRP I booted in before (with the same software version) does not boot any more
I get an error message with adb and the phone reboots.
Not sure where to go from here...

Question Phone is stuck on fastboot page

Hi,
I attempted to flash ArrowOS for my Poco F3 2 days ago but I didn't follow the steps correctly. My plan was to unlock bootloader, boot twrp and install ArrowOS. After I tried this, the ArrowOS loadup screen kept on loading for a hour. I rebooted the device and ended up in the ArrowOS recovery. After some times, I tried to flash the MIUI fastboot rom with Mi Flash Tool and I think I chose "clean all and lock." This caused a problem because I became stuck on the fastboot page and when I tried to reboot, it would go to the Poco startup page briefly before jumping back to the fastboot. I've tried to hold the power button and the volume keys but it has no effect. Also, on the Poco page there was no unlocked padlock which was weird because when I first tried to flash ArrowOS I could see the unlocked padlock. When I checked on my computer using Mi Unlock, it showed that my device was unlocked.
I think I did manage to flash fastboot rom for MIUI using XiaomiToolV2 because it said that the installation was complete.
Another problem is that when I boot TWRP with fastboot from my computer, there isn't any internal storage shown after I click the install button. I think this is because I wiped the device with TWRP when I was following various tutorials. When I try to add a file to the internal storage from my computer it shows an empty folder and any files I copy into it isn't shown.
I would be really grateful for any help as I've been trying to fix this problem for 2 days now. Thank you!
I've attached a video of the phone being stuck on fastboot.

Well I don't own that phone but it sounds like you didn't unlock the bootloader properly and your internal storage is encrypted that's why it shows 0 and that's probably why your having problems. Is there an encryption disabler zip? Your supposed to format data and flash an encryption disabler and than magisk v23 on Samsung devices than boot.

Okay, so I've just used the Format Data option in TWRP which says it will remove encryption on internal storage. But this didn't seem to fix any problems

No, I haven't flashed a disabler zip. Where would I download that. I found a XDA download called Xposed-Disabler-Recovery.zip, would that be it.

Reboot in fastboot. Flash boot and vendor_boot:
fastboot flash boot_ab boot_alioth.img
fastboot flash vendor_boot_ab vendor_boot_alioth.img
fastboot --set-active=a
Reboot in ArrowOS Recovery:
fastboot reboot recovery
Make format data (Factory reset -> Format data).
Flash ROM (Apply update -> Apply from ADB):
adb sideload name.zip
If you want install separate gapps on vanilla buildtype, after flash ROM:
Advanced -> Reboot to recovery
Flash gapps (Apply update -> Apply from ADB):
adb sideload name.zip
Follow what show on device, should be ... Step 1/2 -> 2/2, then flashing ended, can reboot device in system. (on command line can show "(~47%) adb: failed to read command: No error", it normal!)

sounds like you have indeed locked your bootloader. you can check using fastboot cmd 'fastboot oem device-info'
if it's locked, only thing to do i would guess is to try and flash stock rom (not EU custom rom) and hope for the best, then try to unlock your bl again

Also twrp instructions
Installation:
1. fastboot boot twrp.img
2. copy that same twrp image to the device
3. go to Advanced > Install Recovery Ramdisk
4. select the image you copied
5. after that is done, if you were using a custom kernel, reflash it now
6. if you were using magisk, reflash it now
7. reboot to recovery, you should now be able to boot TWRP normally using Power+volume up
repeat step 3 and 4 directly after flashing a new rom, then reboot recovery to flash additional stuff

also, if your bl is indeed locked i for sure recommend you HALT all attempts at flashing twrp or any custom rom. you need to focus on trying to get stock fw back on the device and booting

WOW! Thank you guys so much for your help! My bootloader was indeed unlocked and I proceeded with the steps by Techguy777 and it worked perfectly! I now have ArrowOS booting up and I cannot thank you guys enough. I hope you have a great day!

Also I haven't installed TWRP; Should I install TWRP? Or is ArrowOS Recovery sufficient

WOW! Thank you guys so much for your help! My bootloader was indeed unlocked and I proceeded with the steps by Techguy777 and it worked perfectly! I now have ArrowOS booting up and I cannot thank you guys enough. I hope you have a great day!

enjoy the ArrowOS, it is way better than MIUI. I am loving it since i flashed it 2 days ago!

Wow, if you chose flash and lock like you mention in 1st post and somehow your device remained unlocked, you sir are very lucky!! Glad it's all up and running. Fck knows how it stayed unlocked, but thankfully it did
