So my phone booted into the stock recovery (no TWRP installed) when I accidentally selected the wrong update method in magisk. It kept on rebooting to the recovery even after selecting reboot device and tried clearing cache. Even after that it booted back to the recovery. Then I turned off the phone. And now when the phone turns on it goes to bootloader even after selecting recovery mode. And in the bootloader "Bootloader Version" and "Baseband Version" are blank. This is what it shows;
Fastboot Mode
PRODUNT_NAME - sdm845
VARIANT - SDM UFS
BOOTLOADER VERSION -
BASEBAND VERSION -
SERIAL NUMBER - "Serial number available"
SECURE BOOT - yes
DEVICE STATE - unlocked
PC doesn't recognize it either.
Under device manager it says "Unknown USB Device (Device Descriptor Request Failed)
I'm having 6T 6GB RAM (International)
Bootloader unlocked
Any idea as to why this happens and how to solve it?
Thanks
PC recognized the phone after trying a different USB port. And even detects fastboot.
What should I do to get this booted into the system?
fastboot boot twrp-3.2.3-2-fajita.img gave below error.
FAILED (remote: Failed to load/authenticate boot image: Load Error)
Still selecting "Recovery Mode" reboots to Bootloader

Use MSM Tool to recover the device. That's the easiest option.
Does it wipes the device?
Also I was on 9.0.13. And I could find only MSM Tool 9.0.12.
Alright. So this is how I solved my problem.
First entered
Code:
fastboot --set-active=b
And that solved FAILED (remote: Failed to load/authenticate boot image: Load Error) error.
After that I managed to boot to twrp by
Code:
fastboot boot twrp-3.2.3-0-fajita.img
At first, the phone got stuck at Oneplus logo.
Pressing Vol Up + Power for about 10 seconds turned off the phone. Pressing Power button for a few more seconds turned it back on to bootloader. Enterd the previous code once again booted it to TWRP.
Sideloaded 9.0.13 downloaded from Oneplus site and rebooted.
Problem solved. Everything was saved.

Beast mode nice job and thanks for sharing your fix
Sent from my [device_name] using XDA-Developers Legacy app
I have the same issue..
Is it possible to restore the baseband version by entering this commands?
In my situation, I already wiped and boot into the system.

I get this error by trying your solution:
```$ sudo fastboot --set-active=b
error: Device does not support slots.```
```$ sudo fastboot --set-active=b
Setting current slot to 'b'...
FAILED (remote: unknown command)
finished. total time: 0.000s```
Also tried the other option without better results:
```$ sudo fastboot --set-active=a
error: Device does not support slots.```
```$ sudo fastboot --set-active=a
Setting current slot to 'a'...
FAILED (remote: unknown command)
finished. total time: 0.000s```
Maybe it's because I'm using OnePlus 6 instead 6T?
how was this fixed?
Hi Guys I am Having a problem with my Asus Zenfone Max Pro M2 (X01BDA) , I am not able to flash Twrp or i can't even flash anything via Fastboot.......

i have tried everything but still does'nt work Please help !!!
Check if you are entering the file name correctly with "fastboot flash recovery recovery.img"
Here in recovery.img instead of "recovery" write the filename of the recovery you downloaded.
Is your bootloader unlocked?
same problem here... can't seem find the solution. please help anybody. bootloader has been unlocked, all the name type correctly. but it just FAILED (Write tot device failed (Unknown error)) and the phone suddenly says press any key to shutdown.

Try this:
1. AMD Bug? - https://forum.xda-developers.com/t/fix-fastboot-issues-on-ryzen-based-pcs.4186321/
2. Switch Device from "Charging" to "File Transfer" Mode
3. Install the latest Device Driver or Universal USB Driver - https://www.androidfilehost.com/?fid=2188818919693784734
4. Placed the latest platform-tools with the Img File directly under the C Drive
5. Try another USB Cable
6. Use another USB Port (USB 3.0 Port to USB 2.0)
7. Try to execute Fastboot Command without connecting your Phone,
and once it says "waiting for device" plug in your USB Cable
8. Windows: Click "Change advanced power setting" on your chosen Plan and expand "USB Settings". Under "USB Settings" Section, expand "USB selective suspend setting" and change it to "Disabled" for On Battery and Plugged In.
9. Try another PC
Code:
adb reboot bootloader
fastboot devices
fastboot flash recovery recovery.img
I hope it helps (∩_∩)
Hi,
Today My Asus Zenfone AR stopped working with no apparent reasons or actions performed by me.
When I try to turn it on, it simply remains stuck on the ASUS log screen.
I tried to trigger the recovery mode (POWER+VOLUME DOWN button ) with no success (nothing happens)
I tried POWER+VOLUME UP and I got the fastboot screen. The following infos are displayed:
PRODUCT_NAME - Siva
STORAGE VARIANT - UFS
BOOTLOADER VERSION - 1.21
VERSION - WWZS571KL-14.1600.1712.41
SECURE BOOT - enabled
DEVICE STATE - locked
From the menu I can select 1)start, 2)power off, 3)recovery mode, 4)restart bootloader.
Nothing seems to work, in particular if i select recovery mode, the phone reboots but it remains stuck in the logo again.
Then I tried to follow the steps described by you in: https://forum.xda-developers.com/zenfone-ar/development/recovery-twrp-touch-recovery-t3767745.
adb.exe version 29.0.6-6198805, running on windows10, seems not recognize the device while the phone is in fast boot mode (adb devices shows no output)
Instead, the device is recognized by fastboot.exe (same version). I tried the following four commands with no success:
1) fastboot flashing unlock
FAILED (remote: 'unknown command')
2) fastboot oem unlock
FAILED (remote: 'unknown command')
3) fastboot oem asus-go
(bootloader) Fail to unlock device due to invalide signature!
OKAY [ 0.036s] Finished. Total time: 0.042s
4) fastboot flash recovery twrp-3.2.1-0_CPTB-20180323-03-A002.img
Sending 'recovery' (18672 KB) OKAY [ 0.466s]
Writing 'recovery' FAILED (Status read failed (Too many links))
fastboot: error: Command failed
The phone then turns off.
I suspect the last command failed because of the device is locked but I cannot find a procedure to unlock it from fastboot. (anyway, I have zero experience on android firmware etc).
Can you suggest me on how to proceed?
I am using the OnePlus 7 port for zenfone max pro m1. I was trying to change my recovery from twrp to orange fox recovery but I was unable to do so. It gave me the following error
Code:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot flash recovery D:\recovery.img
target didn't report max-download-size
sending 'recovery' (28872 KB)...
FAILED (command write failed (No error))
finished. total time: 0.034s
I tried to flash the orange fox recovery image through twrp and it got flashed, since then my phone doesn't boot into recovery. it gets stuck at the asus logo. I tried to reset my phone to factory settings using the stock firmware but when i run the "flashall_AFT.bat" file, my phone shows the message "press any key to shutdown" and there is no progress in the command prompt window. Now I cant boot into recovery mood and cant flash anything through fastboot. Anyone has any idea on how to fix this issue?
If i get these message, i am sure, the usb-port is incompatible for the fastboot (maybe the usb3 and fastboot incompatibility, but i'm not sure). Try to use some old usb-hub between phone, and PC.

Use a Good quality usb cable or connect your mobile to usb 2.0 of your pc
It happened to me too , using a normal cable in usb 2 port . and and no problem in usb 3 port.

Same problem I got.
Hey guys, I need help with this Asus Zenfone 2 Laser that:

As someone who has only worked with Google Pixel phones in the past, I'm very frustrated for a few reasons.
Firstly, why the hell is the ONLY WAY to unlock a bootloader through an app that was released in such a clandestine, under-the-table way?
Second, why is the manufacturer gatekeeping the recovery files? The only way I was able to find the stock recovery.img is through a comment on a Reddit post (ironically posted by an ASUS Employee).
Third, I've been scouring the internet for many, many days trying to find any kind of emergency recovery method, but every single tutorial acts on the assumption that the bootloader is unlocked, and that boot.img, recovery.img, etc. can be flashed.
Enough about the frustration. Now let's talk about what I've tried so far.
I tried ASUS Flash Tool (Finding ADB drivers was a whole different fiasco for this device), and came up empty handed, as it doesn't detect the device when in fastboot mode.
I tried using fastboot to flash boot, recovery, system, fastboot, and dnx/ifwi, to no avail.
I tried booting into recovery via `fastboot reboot recovery`, `fastboot reboot-recovery`, `fastboot oem reboot-recovery`, and by holding Vol Down while booting up. They all give the same result, which is just an instant (<1 second) reboot. My best guess is that recovery.img is either missing or badly corrupt, so the bootloader just gives up and exits immediately.
Please help. I don't want an expensive paperweight sitting in my drawer just because of a bootloop that wasn't my fault (seriously this device just bootlooped itself one day, I didn't flash a custom rom, root or anything like that).
Any help is appreciated,
Thanks in advance
you can flash on locked bootloader in EDL mode. search in the forum, don't hesitate to ask for clarity on search results. I give you a starting point.
(don't read the whole thread, it will only confuse you)

Probably a dumb question, but how can I put my device into EDL mode?
I've tried many key combinations in conjunction with plugging it into the computer, and I've tried connecting it without a battery.
if nothing else works you need to figure out test points
https://forum.xda-developers.com/t/...ed-to-unlock-bootloader.4531349/post-87944673
you still have fastboot? try this for EDL mode.
Code:
fastboot oem enter-dload
Good news and bad news. Good news is: I was able to enter EDL mode.
Bad news is, apparently my entire partition scheme was messed up, and upon running "edl w gpt gptboth0.bin", fastboot no longer works.
I have tried flashing aboot using edl ("edl w aboot emmc_appsboot.mbn") and it's not working.
Not to mention that it is almost impossible to find the firmware file with all the factory files such as "emmc_appsboot.mbn". The place where I got my file seemed very sketchy and I'm not surprised if the reason it's not working is because it's the wrong file.
Once again, this is a result of ASUS gatekeeping their recovery files to service centers to drive up repair sales.
If anyone has a link, or would like to provide a donor file, it would be VERY much appreciated.

So yes, I was able to get fastboot back. However, I am now facing another issue.
In order to get fastboot back, I had to run this command
Bash:
edl qfil rawprogram0.xml patch0.xml image_dir
This seemed fine at first, but now, running "edl printgpt" returns nothing. Somehow, the phone is able to boot to fastboot without any GPT partitions visible.
However, when I try to flash gpt_main0, or gpt_both0, the phone now becomes unbootable.
This means, if I try to create a partition table to flash recovery onto, appsboot (and by extension, fastboot) no longer works.
Code:
$ fastboot flash recovery recovery.img
Sending 'recovery' (18115 KB) OKAY [ 0.581s]
Writing 'recovery' FAILED (remote: 'partition table doesn't exist')
fastboot: error: Command failed
"partition table doesn't exist"
If I try to create the partition table, the phone refuses to boot...

So we're you able to find a fix in any way? I find myself in just about the same situation tho for different reasons. I have a radiant max 5g att device i moronicaly tried to download a gsi using the dsu updater, but forgot to unlock bootloader or even enable USB debugging before attempt. So OS system is crashing an saying 'device corrupted' on boot attempt. Recovery mode gets the same result. Was able to use the bugjaegar app to connect ad run the bootloader but every repair attempt is blocked by the fact the USB debugging isn't on. To make matters worse I accidentky hit boot fastbootd command instead of normal and whatever that did wiped out my ability to even connect with bootloader so I'm kind of stuck.

I found many tutorials about fixing bootloops on the Nexus but they all seem to require an unlocked bootloader.
The bootloader on the device is locked. I can see the device in fastboot devices but I can't unlock it.
Any idea how to repair this? Can I somehow flash a factory image onto the device even though OEM unlock is disabled? There is no data on the device that would need to be preserved. I'm ideally looking for a Linux-based solution. more info... ***

Yeah man I've been looking at this problem for over a week now and can't find much online at all to help. Except for this EDLmode some devices can boot into, and apparently you can flash a locked system using this emergency download mode. I dunno still researching.
