Hi,
I was on 5.0, running stock recovery and rooted. Today, installed TWRP for 5.0 on my device. I tried to flash the droid command center widget on my phone usng twrp, and it failed. I also hit the fix permissions option. After that the phone does not boot up, simply flashes the unlocked bootloader sign and shows the moto boot animation for a second or two before shutting down.
I can boot into recovery, and the computer detects the phone. But adb doesn't detect the device. I have the 1092 5.0 OTA on my computer and saved it on the phone in an attempt to flash it thru TWRP, but that failed with the message shown in the img attached. I also tried flashing stock 4.4.4, but that gave an error "Updating partition details" failed.
Can someone help me get back into my phone? :crying: ADB doesn't seem to be detecting my phone, else I'd have tried to install a rom via fastboot.
I have multi-tool v4.1 installed, would I be able to flash a rom (stock unrooted and full wipe is perfectly fine too) via that considering adb does not detect my phone, but the computer does?
Well, that looks annoying.
I've found myself in similar situations when I've accidentally flashed something I shouldn't have. The good news is that if you can boot to recovery you can also probably boot to the bootloader and use fastboot.
Have you tried wiping everything and going back to stock? It's time consuming but at least you'll end up with a working phone.
I had to do this when I put the wrong recovery on a phone and it mangled partitions. Device wouldn't boot.
There are instructions for the moto x here

Thanks for the reply! Color me silly, but would I be able to use fastboot given that when I run adb the 'adb devices' command does not show my phone?

Because fastboot mode can start on your device even before Android loads (and can even run when Android isn't installed at all), fastboot mode is useful for updating the firmware quickly, without having to use a recovery mode.
Adb relies on android booting and usb debugging being enabled and the computer being authorized for debugging (L feature). Fastboot does not. Try booting into the bootloader and then run "fastboot devices" . Mine shows up. I suspect yours will too. If it doesn't then I'm out of my depth here.

Ah yes. For some reason, my fastboot file had gotten deleted from the folder and so the command didn't run. Everything went smooth once I noticed that. Had to downgrade to 4.4.4., but w/e. Thanks @oldcynic
Alright, I somewhat hate Android 6.0, and that's because of my hard time rooting my Nexus 6, which is, at this point, becoming immensely irritating. If I'm allowed to do so here, since this is a Q&A board, I need to ask how the hell to root this thing, because of Android's new thing where I have to install a custom kernal to get root.
All I really know, now, ids that I need to unlock the bootloader of the phone, which I've been trying to do (installed SDK's platform tools, made sure my Nexus 6 Windows drivers are installed, but when I open a command prompt to unlock the bootloader, I'm met with a, "no devices found," response, so I have no clue what to do, and need some help, because with how many tutorials I've looked up for how to do this, and none of them working, I'm about heady to break my monitor. If anyone can explain what the **** I'm doing wrong, or link to a tutorial for how to unlock the bootloader, that actually explains what's needed to do so, it'd be appreciated.

This is how i always root the phone:
- Enable usb debugging and ENABLE OEM UNLOCKING in developer options
- Reboot into the bootloader and type fastboot oem unlock and let the phone boot up
- Flash TWRP in fastboot
- Go to recovery and flash a modified boot.zip (all custom kernels will do)
- Flash the latest superSU.zip, also in recovery
- Done
Here is a tut for the adb setup (Windows) http://www.redmondpie.com/how-to-set-up-android-adb-and-fastboot-on-windows-tutorial/.
- Reboot into the bootloader and type fastboot oem unlock and let the phone boot up
That's my problem. Opening up the command prompt and typing, "fastboot OEM unlock," does absolutely nothing. No prompts come up on the phone. It just sits there, and doesn't do anything.

Do you see a serial number in fastboot if you type: fastboot devices? If not your drivers aren`t installed correctly or adb isn`t setup correctly.

I'm using Windows Vista, so I had to add an underscore, and type, "fastboot oem_unlock," to get the bootloader unlocked. Everything is restoring, now, however, I'm wondering if I'll have to do something similar with flashing TWRP, and the kernal I'm attempting to install. I don't know programming or cmd commands.

You only have to flash the TWRP.img file in fastboot, the rest (boot/superSU) are zip files to be flashed in recovery. I have no experience with Vista so can`t help you there, maybe there is some info about it on Google/YouTube.
So I just got my shiny new Nokia 8 and it seems to be updated to the latest version of Pie. Reading through all the root forums/threads, I'm noticing a couple issues with my phone that I'm not seeing mentioned:
-In Dev settings, OEM unlocking is off and grayed out, I can't toggle it.
-When I try to access download mode/bootloader (volume down/plug in cable from pc) my screen does a little flashy thing and then goes straight to the battery percentage.
-I can ADB devices just fine and see the phone, when I ADB reboot bootloader, the phone gets stuck on a screen showing "powered by android'', with "download mode" in the upper left corner, and any fastboot commands return absolutely nothing.
Any tips or suggestions?
Many thanks

- you cant toggle it because you have not unlocked the bootloader. Sometimes even after you unlock it it will be greyed out, which isnt of importance. To unlock the bootloader downgrade to Oreo November update by sideloading the relevant ROM, then follow the the official HMD instructions.
- Make sure USB debugging is turned on under developer options.
- Are you attempting to boot into the OS or recovery here? Abd reboot is enough to boot into your system. To boot into recovery use adb reboot recovery. Or do it manually using the keys.
Ok, everything I've read so far says to make sure OEM unlock is enabled before you do anything else, so you've confused me now. And none of the guides talk about sideloading the ROM, so you've thrown a new twist with that as well.
USB debugging is enabled, and my computer sees the device via adb devices, but if I try adb reboot recovery, all I get is the little android icon with the red triangle over him, and if I try adb reboot bootloader, basically nothing happens. And I wasn't trying to boot into the OS or recovery, I'm not a noob but maybe this phone is just different enough from what I'm used to I guess.
So basically I'm stuck right now, can't boot into recovery, can't sideload a ROM, can't boot into the bootloader/download mode either.

Actually, thank you, you got me thinking and I was able to get downgraded to the Oreo, got my code from Nokia and unlock.key, now the only thing I'm still having a hard time with is my computer won't detect my phone in fastboot mode. Works just fine in normal ADB commands, but no fastboot...
You'd think my drivers are all fine and that since ADB sees the device, but maybe not?

Im guessing you finally realised they after getting the android icon with the red triangle u have to press volume up and hold it then tap the power key to enter the recovery. Good to know you managed to unlock the bootloader eventually.
A lot of people have been having issues with fastboot, especially on Windows machines . Try restarting the shell or use a different USB port on your computer?also maybe try a different driver version and see if it helps.
I received my new sony 1 ii and have checked and the bootloader can be unlocked and the phone can be rooted. I thought I was away to the races but I'm mystified. I can't get the phone to boot into fast boot.
I appears I have the drivers in place and the phone is recognized by the computer but no luck with fast boot.
I have searched and can't seem to find out why this is. I suspect some kind of driver issue with win10 but when I connect to the computer with the phone off and hold the up-volume nothing happens. I have also tried to boot into recovery mode and that does not work as well. Any help would be appreciated.

On Sony devices you need to power off and hold volume up and plug in the USB cable. That should leave the blue LED to indicate fastboot mode. I'm not 100% sure since it's been a while since I've messed around with Sony devices
Thanks for the input. I have done that and am still unable to action ADB - It is a little confusing since the phone only shows the blue light and nothing else.
If I normally boot the phone it will register as an ADB device. I also find it strange that it will not boot into recovery. The android icon flashes but when you release it boots to safe mode. I assume it is a driver issue but it is not revealing its self to me . Cheers

The blue light is fastboot mode. There is no ui interface in fastboot for sony devices. Just a blue light and black screen.

Same person but had to change user name -- more on the issue
I managed to unlock the boot loader and it seems that at every step for rooting I am running into curve balls. Windows was not working for me so I managed to unlock the bootloader with Linux and going on to the next step I had to go back to windows to find a current factory ROM.
The next issue: going back to the "how to" I am unable to located boot.xxxxx.sin in the factory ROM and the closest I could find is boot_x-Flash-ALL-2389.sin and that doesn't work.
In the boot directory all files are bootloader_X_44 and a combination of zip and sin files
Can anyone steer me through the muddy waters
The factory rom was downloaded through XperiaFirm application

May I know how did you unlock the bootloader? Did you use xperia 1 as your device in https://developer.sony.com/develop/open-devices/get-started/unlock-bootloader/#unlock-code?
I have already installed usb drivers and have the platform tools. But everytime I boot my device to fastboot, whether using "adb reboot bootloader" or power button + volume up, screen only shows black (led is solid blue). I did left it for a couple of minutes, nothing happened.

Yes I followed those. But may I know how long it took you to finish the unlocking?
Install ADB/SDK drivers
Download platform tools
Plug the device
Make sure adb can see my device
Use adb reboot bootloader command
Device booted to fastboot mode
Execute the command with the unlock code
...stucked here
If I miss something. Please do let me know

I assume you are using windows and I must say I gave up trying to get win10 to work and I was stuck at the same place you are. I then switched to linux and it went a lot smoother and I didn't need all those tools as laid out in the description.
In linux you must use the phone to go into fastboot mode if you boot from computer it actually boots to a visible screen on the phone and I didn't have connection that would take the command line commands. Linux is very good because if you are missing something it will give you a link or a command line input when you execute the ADB or Fastboot command.
I have run a windows/linux dual boot desktop for a while now and I'm no expert but coming from the era of command line I can muddle through. Sorry if I can't give you more info on windows but win10 is such a pain and I find that with a lot of things linux works better. If I didn't need adobe acrobat I would not even bother with windows.
cheers

Yes I am using w10. Will try linux later. I have searched everywhere and stucked at the same step. Thank you.
I have managed to unlock the bootloader and root the phone. But problem is. I can't write on the root folder.
More to this I think I might have located the boot file boot_X-flash-all-2396.sin but using magisk it returns no boot image found. I see the guide says use the canary built but that seems to have been shut down, so at an impasse here and am still reaching out for help - damn op phone were never this funky
I might as well put this one out there then -- Is there anyway to flash a op 8 pro in2025 to dual sim - it's the cause of this painful trip
I was reverting my phone to unroot and locked bootloader. And it is saying that "Your Device is corrupt. It can't be trusted and will not boot" loop.
I tried flashing it using the new flasher. But after flashing, it will do SONY boot loop. If I connect it to a charger it goes back to "Your Device is corrupt. It can't be trusted and will not boot" loop.
I can't use Sony Companion since it is saying that my battery is low, and I can't charge the phone since it will just continue looping.
Do you know/have any recovery.img?

Hi all,
I'm encountering a very annoying issue with my brand new Zenfone 8.
I wanted to install the last LineageOS image, but now my phone seems stuck.
Here are what I did:
- Unlocked the bootloader: success with the ASUS APK after a few tries (error 11000 and 11006 ans eventually worked).
- Rebooted to bootloader
- Entered into recovery
- Used fastboot to flash the vendor partition.
At this point, everything looked OK. But then.... :
- Powered off the phone and restarted to bootloader.
- Tried to enter into recovery to flash the Lineage Recovery
But at this point, I had a ASUS logo stucked on the screen.
I can't do anything with adb or fastboot commands.
I tried the method explained here (https://www.asus.com/Content/Android-13-Beta/) to rollback to stock Android 12, but nothing happened too: I looked at the shell script (I'm on Linux) and I reckon that it stucks on fastboot command (the phone is in the bootloader).
Any idea about what failed? The last command used (vendor partition flash) said "OKAY".
And especially, what can I do now? Any way to reinstall the ASUS recovery?
Thanks in advance guys.
Not quite sure what your status is if you say "can't do anything with adb or fastboot commands". I've flashed Zenfones a couple of times (my household has 3 Zenfone 8's on LineageOS) and I had one that went into ramdump. I recovered from that using fastboot to manually reflash all 19 firmware partitions, in both slots. That got the phone out of ramdump, and I got to continue the upgrade to the new LineageOS. So: if you can boot to the fastboot environment, then that would be a road that might leaed you out. But if you can't even get a response to the command "fastboot devices" then I don't know of a course of action for you.
To use fastboot commands I had to run the phone into bootloader mode, then to "recovery" and eventually "fastboot" (I'm note 100% sure but it's what I remembered).
Without that, I was unable to use any fastboot commands like device or flash.
And now the issue is that I'm not able to go to recovery/fastboot again, because I have just the ASUS logo and nothing else.
It looks like that the stock recovery was dead, but I don't know why - and I don't know how to fix/reset it.
From the bootloader you should be able to flash the raw image again, it should flash everything

Good to know - but with which commands/tools?
As I said, I was unable to use fastboot commands from my computer on the Zenfone bootloader.
On the bootloader page, I just have "waiting for devices" and noting else. I had to go into the recovery > fastboot to make the commands work.

On Linux and maybe macs too you need to run fastboot commands as Root (sudo fastboot devices) for example. The raw image script should ask you for your Root password for this reason
Yes I know - I well used sudo for all commands.
The ASUS script asks me for password but then does absolutely nothing - not even a print. I waited a few minutes and finally canceled.
For you, fastboot commands should work on the bootloader screen? (I ask that because the script starts by a fastboot command).

Yes, they work from the bootloader, I always run the script from the BL too. Ironically, I had issues running fastboot commands from fastbootd for installing Omnirom, so I did it all in the bootloader and all worked fine.
I am not sure I can help you more at this point, it looks like it maybe got interrupted mid flashing and now something is wrong somewhere. Maybe if you look inside the bash script file you can find the command that it got stuck on and run that manually if you manage to get fastboot command access.
Strange - they have never worked from the bootloader. I tried that before according to the LineageOS wiki. I thought it was a mistake and use the recovery > fastboot to do that. I dont like that - I hope it's not a local version of the Zenfone or something like that.
I'm not at home tonight but yes I'll try to find commands not requiering the fastboot command.
Unfortunately all commands from the script are using fastboot. And as "fastboot devices" sees nothing, I can't do anything.
I've tried from the bootloader screen (with start, recovery, poweroff option) - from the start screen showing unlocked bootloader warning and from the ASUS logo when I try to start the recovery. I've tried the commands/scripts with Linux and Windows: same result.
So :
- I can't use any fastboot commands.
- I don't have the ASUS recovery.
Speaking of the ASUS recovery, I've found screenshots on internet and they don't have a "fastboot" submenu (I'm not sure it's a Zenfone 8). May had I a different version?
I don't like that. If I don't have others option, I guess that the warranty doesn't work because the phone is unlocked?
I eventually found a solution! I've tried with my old OnePlus cable and fastboot commands start working from the bootloader screen.
I have no idea why my other cable was faulty (it can charge the phone and executes commands from the Recovery > Fastboot menu - but not on the BL screen).
Anyway my problem is now fixed.
Thanks all for help and support.
