Your phone is in fastboot mode, not download mode. Small, but distinct difference.
Since you've installed a custom ROM, your bootloader should be unlocked. However, it may be a good idea to issue the oem unlock command through fastboot anyways. Use "adb reboot bootloader" and "fastboot oem unlock" to ensure that your bootloader is unlocked.
Now, since your phone is in fastboot mode, you can do one of two things: 1. Flash a custom recovery and restore your device to stock, or 2. Flash a custom recovery and continue using a custom ROM. Either way, you will need to install TWRP or another custom recovery image of your choice. The TWRP thread is located here: http://forum.xda-developers.com/tmobile-lg-v10/development/recovery-unofficial-twrp-t3239740 Since you're already in the bootloader/fastboot mode, all you would need to do is download TWRP and use "fastboot flash recovery twrp.img" and then "fastboot boot twrp.img" to install TWRP. Please note that the 'twrp.img' will vary depending on which version you download, it will probably look more like 'twrp-2.8.7.1-h901.img'. You can just rename the file or use the full file name in the fastboot commands.
Once in TWRP, you can flash whatever ROM you want. To restore your phone to stock, go to this thread and flash the .zip in TWRP http://forum.xda-developers.com/tmo.../lg-h901-stock-images-device-restore-t3241170 after doing the standard wipe procedure. :good:

I'm kinda in the same boat now except that I already received the replacement device. Need to re-lock the old V10, but adb won't recognize my device at all. Any more option when that's the case? I can get into both download mode and fastboot. Phone is recognized by LGUP in download mode, but not by adb in fastboot mode for some reason.
(I've verified connection and driver using the other V10, the other V10 is recognized just fine)

Yep. Your phone boots and everything, correct? Just factory reset it (Settings > Backup & Restore > Factory data reset). After its been reset, unlock it, turn on Developers Options, and enable USB debugging. After usb debugging is turned on, connect the v10 to your PC and be sure to hit "Always allow" when prompted by your phone. ADB should now be able to see your device.
If you can't get it to boot up, try restoring through LG UP/Bridge. I don't use any of LG's software, so I'm not sure what those apps can do and whether or not you'll be able to restore through them.
If nothing else, your phone is recognized in fastboot mode, so you can always manually flash the stock system images as well. You want to use the "fastboot flash boot boot.img", "fastboot flash recovery recovery.img", and "fastboot flash system system.img" commands After downloading the stock system images located in this thread: http://forum.xda-developers.com/lg-v10/development/lg-h901-stock-img-files-boot-recovery-t3238638
If you haven't ever flashed system images from fastboot, please read this first, as I am not responsible if your phone turns into a paperweight! https://developers.google.com/android/nexus/images#instructions While the instructions are for nexus devices, it works pretty much the same, except you'd want to use the individual commands instead of a flash-all script.
Hope this helps!

Thanks for the follow up! No the phone would not boot at all and kept stuck at boot loop. I ended up just doing the OEM Lock and call it a day, the old device just won't boot to anything at this point.
I tried fastboot flash recovery recovery.img but it's giving some kinda kernel panic message and I was never able to get into recovery. This reminds me of the time when my Note 3 eMMC was fried, it wouldn't give a device ID to adb.
I think I am in the same boat too. I've been OEM unlocked yet recently my phone won't keep the TWRP recovery and keeps putting me into bootloop. I can't install a ROM and only thing I can do is fastboot mode. What did you do OEM lock the device? I am hoping that solution will get rid of that message bootloader unlocked during the bootloop and then I can try and get it serviced.

Hey guys,
i've got the following problem: Unlocking the bootloader, installing TWRP and other ROMs went hassle free and worked flawless until recently.
Now, after having to reflash a clean OOS 2.2.0, it says the bootloader is locked again. TWRP is still installed. When trying to unlock the phone, it just boots to TWRP (which shortly prints an error message, but its too short to read) and shows that the bootloader is still locked in fastboot.
The problem is similar to this one:
https://forums.oneplus.net/threads/opo-back-from-the-dead-story-of-a-brick.144155/
In that thread, a solution is pointed out -- namely, this one:
http://forum.xda-developers.com/showpost.php?p=54251992
The script is for OPO only, so I'm left in the rain. Do you guys know any other way out of my misery?

Install stock recovery and unlock bootloader again...
I'll give it a try. Would you point me in the direction of where to find the recovery.img for that?
EDIT: Phew, did it. Your way worked. I can't even count anymore how often I wiped and reflashed the whole thing in the last 24 hours...
I have exactly the same problem. I have the stock recovery file. Can i just flash it with TWRP ? and stock recovery will be loaded? because i can't use fastboot to load i because its locked
reboot into twrp
copy Stock_recovery.img to device folder
go to install
at the bottom select install image

Hey guys.
SGP312 model here, unlocked bootloader.
not sure what i did wrong here - i got to Fastboot mode and the blue light is on, when i run "Fastboot devices" i get the device name.
so i followed the explanation here: https://forum.xda-developers.com/xp...pment/ub-twrp-v3-2-1-xperia-tablet-z-t3735110
and did: "fastboot flash boot twrp-3.2.1-0-pollux_windy.img"
however, now my phone won't boot, and when i type "adb reboot recovery" i get "error: device not found" (even thought "Fastboot devices" gives me a response")
i tried fixing it with Flashtool, and everything works well until i get to "Wait for Flashmode" and im instructed to "unplug, power off, pres vol down, plug in USB cable" - this simply doesn't do anything =X
so.... how do i get out of this? all i want to do is install one of the newer roms from the forum (either Marshmallow or Oreo)
can anyone help me get out of this issue i've gotten myself into?

you flashed recovery to boot. So only recovery exists in boot section.
Of course tablet won't boot afterwards, as there is not kernel.
Download custom rom you want to install, unpack boot.img from roms zip files and flash via "fastboot flash boot boot.img"
Afterwards enter recovery and flash custom rom zip, gapps or whatever you need.

I did the same thing knowing the outcome and then successfully flashed Lineage.
For future reference, with the Xperia Tablet z where should I be flashing the recovery if not to boot:
"fastboot flash *What goes here?* twrp-3.x.x-0-pollux_windy.img"

Hello guys.
I have been in the android world for a while, but just got this device.
I had tried to install twrp with no success. I already have bootloader unlocked by me with no issues, following a tutorial here. When I flash twrp it shows success but when I try to go there ñ, it just goes to miui recovery. When I boot directly from fastboot with:
Fastboot boot twrp.img
It goes there with no issues but of course, data is encrypted. So I want to install it in order to format my data and be able to root. Any ideas?
I researched and found that one way is to install a dev rom, but I really want to remain on stable one.
Thoughts?

Put a copy of twrp.img in your sdcard.
Put other copy of twrp.img in adb folder of your pc.
Type from a cmd with admin rights with device in fastboot mode connected to pc fastboot boot twrp.img and when you reboot to twrp slide allowing modifications and then flash your twrp.img through same twrp recovery
The first command will do that device can boot to twrp but it´ll not flash it in recovery partition.
The second action will flash it permanently onto your device.
Probably you´ll need to format data in order to can reboot to system again.

Thanks! I solved it after taking a look for a while. I do not have an sdcard, so I flashed it and then fastboot booted it, then I reboot recovery to make sure it was flashed and then formatted data. I worked flawlessly!
Hi all,
I appear to have done something wrong when flashing my device with boombox and flashing twrp. I seem not to be able to access recovery so I can update my boombox rom. I have tried button combinations, I have tried fastboot boot twrp.img in bootloader which just reboots my system, I have tried booting directly from home screen using adb which registers an error and I have tried re-flashing but unfortunately I cannot access recovery.
Any way I can get into recovery without erasing my data?

If you're rooted, give the reboot recovery app you installed after bootloader unlock root privileges.
If not then use the exact same PC ADB commands to boot to TWRP like during bootloader unlock.
I'm confused why you mention flashing TWRP after Boombox. Surely you didn't do that. You already had TWRP.
I am rooted, Recovery reboot just reboots the phone, I have tried to get into twrp by reinstalling but again does the same things just reboots the system after the corruption warning screen. I've also tried to install from the bootloader with the fastboot boot twrp.img command but it simply says waiting for device.
Sorry turns out I was flashing the wrong file from another tutorial, I was flashing 3.1.1 instead of 3.2.1

Then you didn't follow my bootloader unlock and root guide. I never mention that other TWRP, much less link to it.
You're going to have to load into Download mode and use fastboot commands, but you say you couldn't get past flashing TWRP.
Uninstall the LG Mobile Driver if you have them, then reinstall.
1st, reboot into OS, then open up Device Manager and change view to Show hidden devices. You should see a new category named 'ADB Interface' and underneath that 'Fastboot Interface (Google USB ID)'.
If not, you will also see 'ADB Device' for Other Devices category:
right click that to update driver software ---> Browse my computer for driver software ---> Let me pick from a list... ---> Show all Devices ---> Have Disk ---> Browse ---> C:\Program Files (x86)\LG Electronics\LG Mobile Driver ---> 'lgandbus' ---> 'LGE ADB Mobile Interface'
Download adb/fastboot software, download Joan TWRP 3.2.1 img file and place it in adb/fastboot folder, then send your phone into Download mode:
Open up cmd and type the following after changing directory to Adb/fastboot folder: fastboot devices (see if your device is there), fastboot flash recovery TWRP.img or (whatever file is named).img, then fastboot boot TWRP.img or (whatever file is named).img
I recently bought an unlocked Moto G Play 2021 with the intent of learning how to flash custom rom's etc. The steps I've done so far are below.
Went to Motorola's site and got the code to unlock the bootloader
Waited for the "OEM Unlock" button to be available in the Developer Options menu.
Followed the directions Here to try to get an unofficial version of TWRP installed.
when I type fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img Using the vbmeta.img from the link above, I get some kind of anti-rollback error and can't boot to recovery.img
So far, what I've found says I need to be on Android 10 for this to work but I can't find a stock rom of Android 10 for this device. Electimon posts AOSP builds for this phone Here so I assume there's a way to get this to work, I just don't know what it is and I've gone through these threads a few times now and can't piece it together. Any assistance would be greatly appreciated.
Additionally, thanks Electimon for doing those AOSP builds.
Try to download Miracle Thunder Modified (Withouth Box) like there are other tools, but if not, just try to root. kind of for you to root, download the TWRP app and install or use Flashify to flash img using root

I'm not sure entirely what happened, but after I used the TWRP app my phone bricked and I had to use the Lenovo rescue app on my pc to factory reset it.
First update your phone
Then download twrp from

Then adb reboot bootloader
Then fastboot flash recovery MotoGuamnaFixed2.img
then you have twrp installed then you can go thru the steps at

Thank you for the response!
I made sure my phone was on wi-fi and checked for updates. I then rebooted to fastboot and flashed recovery to the MotoGuamnaFixed2.img. I still got a blank screen when I tried to reboot to recovery. I then rebooted to fastboot manually and did
fastboot flash recovery_a MotoGuamnaFixed2.img
fastboot flash recovery_b MotoGuamnaFixed2.img
It said ok both times, and when I try to reboot to recovery, I get a blank screen that I can't interact with. Pressing the power and volume buttons does nothing. Rebooting and letting the phone go through the boot process, to include waiting for the warning about the unlocked bootloader to go away results in a blank screen.
I also tried booting to fastboot and selecting "Recovery Mode" from the fastboot menu. Same result. That being said, I followed the instructions in the second link anyway, which are
fastboot -w
fastboot update (filename).zip
Now my phone has a blank screen I cannot interact with, but when I type "adb devices" I see the phone. Typing "adb shell ls -l" shows there is definitely a file structure there.
Just download the rom for the version that your device is unzip it and manual flash each one to the correct spot except recovery flash the twrp and then reboot and let me know look at flash file.xml to see where to flash each IMG and bin to make shur you download your rom and not another one for the same device but different carrier what it sounds like to me is happening is you downloaded the wrong ROM when you tried to do a force update
Send me a screenshot of your about device screen please I might need to make a change to a few things to get it working
I'm stuck in a boot loop right now. WIll the output from fastboot getvar work?
What carrier do you have
Download your rom first then follow my last post to get it back out of a bootloop

It's an unlocked phone, no carrier, no SIM. I did the factory reset with the Lenovo rescue tool and sent you the screen shot of the device info page.
Update - svoc has spent a crap ton of his personal time trying to help me with this. I've learned a bunch and wanted to publicly acknowledge his willingness to go way above and beyond trying to get this working.
I don't understand why I can't get twrp to boot I'm not for shut what the problem is if any one has any idea please let me and I will try
Big thanks to svoc for all the phone calls and troubleshooting my device, that is apparently possessed by at least 3 demons and a donkey. There are two links below. The first is the link to the intstructions that worked.
The second is to the compressed file that gave me a degoogled android. It's really, really basic and you'll have to side load the app store of your choice onto the device but it works.
*NOTE* I have not used a sim card or tested the cellular capability. If you do the things below and it doesn't work, reboot to bootloader and flash the radio.img with the one from your stock rom, which can be obtained from lolinet.
Any custom ROMs out there for Moto g play 2021 (guamna)?
Can't find any custom ROMs for this device. I guess it is too early. I'll probably have to get another phone. Can't even find a twrp for it. New to this. Any suggestions?
