Can't access Fastboot mode/ADB - OnePlus 5T Questions & Answers

So, I flashed Derpfest A12 ROM, It boots fine but gets stuck on "getting your Android 12 Ready" screen with the animation. I can access wifi and visiblity options but not settings. I flashed TWRP from the official website to install the recovery. But now when I reboot and press Volume Down, TWRP is stuck on boot animation. So I thought just reset using fastboot and start again and pressed volume up and power button but it does NOT work. I tried the volume buttons again in the rom [i can change volume in the starting screen] and they are working. I can press volume down and power button to reboot into recovery and it works fine but gets stuck. So, I just want to have access to adb or fastboot to reset this phone but neither seems possible. I Cant enable advanced reboot in the starting screen. Fastboot doesnt work. ADB not recognizing as it is a new rom and havent enabled it [i enabled in the previous rom]. Thanks for you Help in Advance!
P.S. I have tinkered POCO F1 fairly so I am not totally new to this scene!
EDIT: Thanks for all the replies! But I solved the problem, Idk how but i got access to fastboot mode after some tries and reflashed everything and now it works, also I use linux and the adb drivers and fastboot were in repos so it was easy.

hello,
I am a novice and use a translation tool to write to you (sorry if there are errors...).
Ok I already installed roms (but a long time ago on a OnePlus One...
I have an OP5T, I want to install lineage Os 19.1 on it.
I followed the tutorial on the lineage wiki.
I installed ADB and fastboot well, as well as universal adb driver.
I'm on windows 11, it works.
I enabled debug mode
The adb reboot bootloader command works, so the tel is well seen by the pc and the tel restarts in fastboot mode.
Then nothing, no command (oem unlock) works, the computer does not seem to see such after restarting in fastboot mode.
I read some topic on the net that say that the phone must be in "battery charging" mode and not "file transfer". Me to be visible by adb I have to put it in file transfer mode, otherwise it is not seen.
If I put in recharge mode, same thing to do.
Do you have a tip or should I give up?

You need to install not just the adb drivers, but the fastboot ones as well, see this guide for example. This driver is the one needed for fastboot.
My devices have always been in file transfer mode btw, I've never heard of it needing to be in charging mode only.

No, you don't have to be in "charging only" vs "data transfer".
Still, those of us who distain to be plebian keep our devices in "charging only" (with ADB on) as MTP is beneath our contempt.
(Actually, the problem is that the USB VID/PID sometimes changes with each mode and that you may not have a driver loaded for ADB only.)

[Q] Using Nexus Root Toolkit without USB Debugging enabled

I have a 2013 Nexus 7 wifi tablet, bootloader locked, with USB debugging disabled. It decided mid-activity that all it would like to do in life is display the "Google" image on the boot up screen.
I can access the bootloader so I tried doing the standard wipe in recovery mode but that did not work.
Investigated Wugfresh's Nexus Root Toolkit. Drivers (Windows 7) are installed but under Step 4 of the Full Driver Configuration guide it is unable to find the device as an ADB device, even though the device does show up on my Device Manager (but only as bootloader interface, not ADB). Tried to use the unlock feature anyway but on the tablet it just gets stuck on the "unlock bootloader" screen after trying to run the unlock tool (choosing "yes" by pressing the up volume button to scroll to the yes option, followed by the power button to select it).
My questions based on this are simple:
1) Can I unlock this device without having USB debugging enabled? If so, how?
2) Can I restore to factory stock settings without having USB debugging enabled (and not using recovery mode on the device itself, as that does not work)? If so, how?
All of the tools I have seen thus far require that USB debugging be enabled on the device. Since I can't actually boot up the device, there is no way to make this happen. I don't really care about any of the data on the device, I just want it to function again to avoid buying a new one.
Stop using a toolkit. Your device will never be recognized by adb when booted into the bootloader.
Unlocking the bootloader is simple if you have the Windows drivers set up correctly. Open command prompt with admin privileges, type 'fastboot oem unlock' and done. This is why I hate toolkits.

I believe this also requires that USB Debugging be enabled. I would paste links but the forum prevents me from doing so since I just signed up.
If I am incorrect in thinking that USB Debugging must be enabled for this to work, then please let me know. All I really need is clear instructions on how to hard reset the device without USB debugging enabled. Unlocking just seems to be a prerequisite for that in most of the tutorials I have found so far.
You can flash the device back to stock with wugs without adb. There should be an option you pick under the factory restore button that says "soft bricked" which tells wugs that it needs to go straight fastboot mode instead of trying to restart the tablet with adb.

Thanks for your reply. I have tried this option without the ADB (but with my computer recognizing the device). Since it did not work I expect the device is well and truly screwed (the recovery mode factory reset also does not work on the tablet itself).

Couple of things:
1. You may also have a driver issue, I was playing with this the other day on both my Nexus 5 and Nexus 7. My nexus 5 worked fine, but later that day when i tried my nexus 7 I had troubles with my PC recognizing the N7 in fastboot mode. It would be fine in ADB and would reboot, but then the computer would freak out when it saw the fastboot device. Sometimes it would kinda work, sometimes the N7 would freeze on the bootloader screen or fail to flash during the process. It even locked my PC at one point. I completely uninstalled(per the Step 1 instructions in Wug's) all Android associated drivers(Samsung, LG, Asus, whatever. Kill them all) on the PC and reinstalled and it solved the issues. It sounds like maybe your PC is failing to flash properly like mine was.
2. Not sure if you tried this yet but; go to Options Menu>Flash Stock Tab>Check "Enable 'Force Flash Mode' . . . " Then try to flash stock + unroot again with the soft-bricked option selected. This basically makes Wug's ignore the check process at the beginning of the flash. I had to do this for both my N5 and N7.
Keep in mind, you will lose EVERYTHING on your N7 if you unroot and flash, including your internal storage.
Yeah, it does not seem to want to do the unroot + flash even with the override of checks. It seems unlocking is really a prerequisite for that tool (according to the text that appears as it proceeds), and unlocking appears to require the USB debugging. If it really can be unlocked without that, then it is not cooperating and just getting stuck on the unlocking screen. I expect it is now a very expensive paperweight.
All of this nonsense just over a year since I bought it, of course.
Try it with another computer, another USB cable...
I'm in the same boat, can't get it to unlock so it's essentially dead now
I've tried original and a G3 usb cord and nothing, front and rear USB ports, just will not unlock, almost to the point of sending it on and paying to get it fixed if possible , will try another computer first
Can you boot manually into fasboot mode and do flashing full stock firmware for ur device..
Bcoz I thinks you don't need usb debugging when on fastboot mode..
if you want to use toolkit, you must setup all driver for ur device first using the toolkit.. but you must do it when ur device is full "working", not when It's just stuck on google image... that's ur main problem now ...
you should try install the driver again on new "fresh" pc ....
Good luck bro... :fingers-crossed:
Did you try to manually unlock it? Boot to the boot loader screen(down volume+power) and the fastboot unlock it using the cmd in windows?

I can boot into fastboot mode but when I then switch to recovery mode manually to reset it does not go to the recovery mode screen (it did at first, but now just gets stuck on the sick robot screen, then on the "Google" loading screen).
I can try the drivers again on another PC, but I have a feeling that won't fix anything.

I looked into this a week or so ago and I think I determined that it would also require the USB debugging to be on (at least from the tutorials). Do you have any recommendations of tutorials on this process? Screwing around with this stuff is not really my bag.

Ok.., Your have no choice by now, you'll need to find a working driver for your PC to get recognize your tablet when on fastboot mode..
I've got this issues before when I want to update my tab using toolkit...
My PC can recognized my tab as adb devices, but when it's reboot to check fastboot status it fail to detect my device is on fastboot mode..
But maybe I'm so lucky that day, Moboginie notification has pop-up and it's has searching and found the driver and fix it itself ...
Then i try again and this time it's has no problem at all till now... I still can access my storage using Moboginie but until now window explorer still fail to recognized my N7...
It's so weird isn't it ...
Try Moborobo

After the recovery screen with "sick" Andy, did it automatically begin to reboot? If not, you know that it's very tricky with the power+vol up button (sometimes I think it's power+both volume buttons that works) to access that screen in recovery (the one past sick Andy). Sometimes I've tried five or six times. I have twrp so I can't check it out right now.
As far as adb/fastboot drivers set up to run any commands, I thought they were required. I'm not certain about USB debugging. It seems you've tried with your device in fastboot and running Cmd (fastboot oem unlock) from your fast boot directory. Do you get a device code when you enter [fastboot devices] while in that directory? If not, your N7 will not accept fastboot commands.

How to turn on the device without using on/off button?

Hi. My all side buttons the phone doesnt work any more, it was not a big problem until my battery run out...
Is there is any way to boot it up without using power button? for example with PC or something but of course without losing data??? Please help I need to boot my phone, at least once..
any one people? someone in here definitely should know something about it. xda-dev always do
Any way to do it through ABD?
Try plug it in usb and check if it connects to adb. If yes then type adb reboot. It will be booted to home screen. Else u can try by pressing the volume up and plugin the usb cable it will connect to fastboot then type fastboot boot system.
thanks for trying but it doesn't work...

@Sw1pe, if your phone is turned of, connect it to your computer while holding the volume up button. Blue led will glow on your device, your phone is connected in fastboot mode. Now open a command window and type "fastboot reboot" without the quotes and voila. Your computer must have adb and fastboot installed for this purpose. Similarly there is also a command for shutdown command but not for fastboot, but for adb. Hopefully this helps.....

Thanks mate thats a good method, I knew it but the problem is like I did mention in the first post, that all my off my side buttons doesn't work, including volume amd camera button... So im more unlucky than you though. But there is even bigger problem, I don't care that much about the phone, I could just send to incurance. But the problem is as I found out recently, I have very important files for me in phones memory... Thats where this situation makes me extremely unlucky... As those files supposed to be in my SD and I always thought they are until this happened... is there is any way to get those files out?? I got developer mode / usb debugging enabled on my phone. If I send it to incurance I will lose those files... :crying::crying:
@Sw1pe did you get your phone on in the end? I have the same problem

MOTO G6 - Qualcomm - EDL Mode

Hi,
I'm after some advice, how do I place the Moto G5 in Qualcomm mode or EDL mode.
I have entered the bootloader by holding down and turning the phone on, this allows me to use fastboot.
From there I can scroll down to QCOM, but when I press the power button it boots into the normal system instead of EDL mode.
I have also attempted from within fastboot to use:
fastboot oem edl
fastboot oem qcom-on
fastboot reboot emergency
and
fastboot reboot-edl
Although non of these have been sucessful.
I also have access to an EDL cable, although, when I plug the phone in, then flick the switch 10 seconds later, it does not enter EDL mode, it just charges.
The phone sometimes shows as File Storage Linux USB Gadget in device manager, although it is inaccessible, I have updated the laptop to use the qualcomm drivers, although I don't think it will ever recognise it if I can't put the phone into qualcomm mode to begin with.
Any help would be much appreciated.
What are you actually attempting to do?
This mode is generally used to unbrick a device but you have access to the bootloader/fastboot mode and you wouldn't use edl mode to unbrick this device anyway
It's also used on some device to unlock the bootloader but again you wouldn't do that with this device
So without knowing what you are trying to achieve I can't give you any advice
Technically if you start the phone normally then enable usb debugging in dev options then connect phone to PC and in a terminal window where you have adb set up type
adb reboot edl
Not all devices support this mode though and I've no idea if this one does

Without going into too much detail as to why, there are tools I have access to which can be used to take a full back up of the entire memory block of the phone when it is in Qualcomm mode.
I cannot access adb on the device to use "adb reboot edl" so I am limited to either trying to activate Qualcomm using a button combination or via fastboot, unless you can advise another way.
Any help or a point in the right direction would be much appreciated.

It's not dodgy, but I fully understand.
Thank you anyway.
try fastboot -i 0x2b4c oem ​​reboot-edl (it's working for LENOVO ZUK Z1 and ZUK Z2)
You can try (if you can/have the TWRP image) to flash TWRP and in reboot options select EDL.
In case the bootloader isn't unlocked you can also use fastboot boot [TWRP image name] to boot directly into TWRP without flashing and then repeat, go into reboot options and select edl.
Not sure if it works for you, if it does let me know that I have helped!

I need help too. So, I own a Moto G5s plus sanders. I unlocked its bootloader the day I got it. Didn't keep any backup and rooted it. I Also installed dot os based on android 11. But my 4G Volte connection was finicky. So, I decided to use a Volte zip patch. But, anyways I flashed the zip via TWRP and tried to reboot. But the phone didn't turn on after that. After a few minutes to my shock I understood that I hardbricked my mobile. No button combos, nothing worked. Anyways in my desperation I found a YouTube video showing the use of blankflash to revive a phone and lo and behold I used the procedure to again restore my device. It booted to the fastboot interface. But my happiness was short lived. My baseband was unknown at this point and the bootloader was I dunno downgraded to 0.5 inplace of 2.12. But, more importantly the unlock status was lost. I unlocked it again and all went well. I could even flashed TWRP. but then I realised I couldn't upgrade my bootloader. I couldn’t do anything. It's always gives a "security downgrade", "preflash validation failed" and "permission denied" error. I even tried RSA official rescue tool from Lenovo but even it was unsuccessful. It was never unsuccessful before that. Not even with a unlocked bootloader. I researched for days and tried custom ROMs. I flashed stock images. Nothing brought back my baseband and IMEI. When I type "fastboot oem unlock critical" it gives me permission denied error with a message. "Need OEM signed bootloader." I think the blankflash bootloader is the root of all evil. I need to change it and therefore I need to enter the edl mode. I have tried all adb commands and fastboot commands. The phone reboots okay after those commands but never goes into edl mode whatsoever. I am also ready to do a controlled hardbrick of my device to go into the edl mode so that I can use my device again with a proper bootloader and a properly working fastboot. Please help

G7 detected by LGUP while in download mode, but not detected by ADB

I'm currently trying to follow this guide on how to install Magisk: https://docs.google.com/document/d/1fdeO9jmm8ewwRX_G0MaGHsVfIVtxgh0yRK0-Yypcl_E/edit"]https://docs.google.com/document/d/1fdeO9jmm8ewwRX_G0MaGHsVfIVtxgh0yRK0-Yypcl_E/edit (I can't make the link clickable since it's my first post) but it's in poorly worded English and I'm not sure if I'm doing it right. I've gotten into download mode by turning the phone off, holding volume up, and connecting it to a PC via a USB cable. As far as I can decipher, the guide says to reboot into bootloader through ADB from there. Thing is, ADB doesn't detect my phone being plugged in, but I know my PC detects it because LGUP detects it just fine. I've also tried booting into the bootloader by holding volume down while plugging into a PC, but that just turns on the phone. Doing adb reboot bootloader while connected and on just restarts the phone. If it helps, I did manage to get it into recovery mode through adb reboot recovery, but all I get is a 'no command' error.
If any of you Android wizards could help me out, that would be great!
You should reflash firmware ULM11g to bring back fastboot; after that read carefully before do something

Boot loop issue: cannot get into fastboot from "no command" screen

Hey everyone,
A2 lite phone is in bootloop - allegedly (not my phone) "out of nowhere". The user does not do any fancy things like flashing, and this has not been done either.
Phone is on continuous boot loop, and sometimes (really seems randomly), the device starts up in the "no command" mode and stays there for a while. I read that we could go into fastboot mode by pressing "power button and tapping volume up key", but this doesn't do anything.
I've tried this thread: https://www.the***********.com/boot-xiaomi-mi-a2-fastboot-mode-recovery-mode/
But I'm not even getting into fastboot.
I'm almost thinking that the volume buttons are just broken, though from the feedback of the buttons this doesn't seem realistic.
EDIT: ok, now I'm somehow able to get it into fastboot.... sometimes. Now I'm here:
I switched the partition from a to b, but it still goes into bootloop. Then I switched it back to a, still bootloop. Then back to b. Still bootloop! But at least now sometimes I'm able to get into fastboot. No matter what kind of commands I'm typing in the cmd console, after about 10 seconds on the fastboot screen, the phone just reboots.
idk, it looks almost as if both partitions have the bad android 10...
Do you guys have any idea? Please let me know if more info is helpful.
You go into fastboot mode by holding Vol Down + Power button. So try holding Vol Down and Power button at the same time to go into fastboot mode. (Don't tap it)
Go here and grab the image you prefer (latest should do the trick) : https://forum.xda-developers.com/mi-a2-lite/how-to/fastboot-xiaomi-mi-a2-fastboot-images-t3824871
Then go ahead and follow this guide here to flash the stock ROM : https://c.mi.com/oc/miuidownload/detail?guide=2
This will wipe the data on the device, but it seems like you have no other option at this point. Cheers.
Thanks! I've tried that now. It starts flashing the device until... after about 10 seconds, the phone reboots from Fastboot mode .
As per this page: https://twrp.me/xiaomi/xiaomimia2lite.html
I've tried to do a recovery via TWRP. If I execute `fastboot boot path/to/twrp.img` then I go from fastboot to TWRP (the teamwin logo), but right after that the phone already reboots.
https://www.xda-developers.com/how-to-install-twrp/ - I don't know if it means anything, but when I execute `adb reboot bootloader`, the console returns `error: no devices/emulators found. If I execute `adb devices`, it does not list my device. However, if I execute `fastboot devices`, my device is listed.
I installed ADB usb drivers, so when I get my phone connected in fastboot, it shows up as Android Bootloader Interfacee in device manager. So not sure what's going on here, but it's all weird.
What I'm facing is very, very similar to https://www.reddit.com/r/Xiaomi/comments/4ltzt9/xiaomi_mi_note_boot_loop_even_in_fastboot/ <-- but that thread is a bit of a dead end (and 3 y/o)...

When the device is in Fastboot mode, it will only be recognized as Fastboot. Only when it's properly booted, the device can be recognized in ADB, so no issues there.
I assume your bootloader is already unlocked as you have successfully booted into TWRP. You might try EDL (Emergency Download Mode) flash as a last resort :
Download MiFlash (20160401) from here : https://www.xiaomiflash.com/download/
You're downloading that particular version because it is able to EDL flash on your phone. Install the MiFlash you've downloaded and open it, then put the phone into fastboot mode. Connect it to your PC and use this code to take the phone into EDL mode:
Code:
fastboot oem edl
After you hit enter, you will see the screen turn off and notification LED blinking, this is normal. This means the phone is in EDL mode. Open the MiFlash you've installed (likely in C:\Program Files\Xiaomi\MiPhone) and browse to the ROM location and connect the phone. Choose "Flash All" and start flashing.
After the EDL flash is complete the phone will not reboot. It will stay in EDL mode. You need to disconnect the phone from PC and hold power button (about 10-15 seconds) to boot the phone. If the phone boots properly, you can go into fastboot and connect it to PC, then use:
Code:
fastboot oem lock
to relock your bootloader. Try it and let me know. :fingers-crossed:
Thanks for the continued help!
I've followed your steps - When I run fastboot oem edl, the console returns "... okay [ 0.0202s] finished. total time: 0.022s" and the phone turns to a black screen (no notification led blinking). Then... after a couple of seconds, goes back into the boot loop .
Something maybe to note: every time that my phone starts up, it (1) shows a screen saying "Your device software can'tbe checked for corruption.Please lock the bootloader.", and then slides down to the typical "androidone" white screen before it reboots again.

The screen with the ugly text is normal, since you have an unlocked bootloader, it's there to warn you that the device's software might've been tampered with. On the main subject though, I'm out of ideas. You might try booting the phone by holding Power + Vol Up, which should normally boot into stock recovery or wipe the data on the device. But I'm slowly beginning to think that this might be a hardware issue rather than a software issue that I can help you to fix.
Under normal circumstances, EDL flash is the way to fix any problems you might encounter with the software, that's why it's called the Emergency Download mode. But since we're past that stage, I believe I will not be able to assist you further. Hope you can fix your device my dude/dudette!
If the phone gets out of fastboot mode your phone does not get recognized from your computer. Try to delete fastboot and minimal adb and download the latest version. [https://forum.xda-developers.com/android/general/tool-adb-fastboot-installer-tool-windows-t3999445]
Open MiFlash, click Driver left on the top and install them.
Set path to the downloaded firmware. Now boot into fastboot, once that is done connect your USB cable to both, computer and phone. If this doesn't work try different USB-Ports and USB-cables. Some work, some don't. This might be the reason for leaving the fastboot mode.
Click refresh and see if your device appears

What did change now after installing these drivers: https://forum.xda-developers.com/android/general/tool-adb-fastboot-installer-tool-windows-t3999445]
I did try some other USB cables. The one I've been trying triggers the windows sound for "new device successfully connected" when I boot the phone up in fastboot, and then of course gives the "device disconnected" sound when the phone then reboots. With another USB cable in this case, windows just states: "USB device not recognized". So it seems like the cable I haven't been using is defect .
I'm unable to use MiFlash at the moment so I can't explain the whole procedure with installing the drivers in MiFlash. But there has to be something like "Install > Drivers" or something. Maybe someone else can help out.
Try to use the working cable again, open a command prompt and type: fastboot devices
Then wait for an answer, post it here and see if the phone reboots again or if it stays in fastboot

Hey everyone,
A2 lite phone is in bootloop - allegedly (not my phone) "out of nowhere". The user does not do any fancy things like flashing, and this has not been done either.

The response by marstonpear below makes sense.

You go into fastboot mode by holding Vol Down + Power button. So try holding Vol Down and Power button at the same time to go into fastboot mode. (Don't tap it)

https://forum.xda-developers.com/sho...php?p=79365091
Follow the instructions, as dat was how i revived mine. Hopefully it may help u.
Note; wen using twrp, preferably use " twrp - offain "
Miflash tool:
Link 1: https://www.xiaomiflash.com/download/
Preferably use Link 1 & choose either 2016, 2017 or 2018 versions. They come preloaded with the drivers u need
Link2: https://xiaomibuzz.com/downloads/download-xiaomi-mi-firmware-flash-tool-latest-version-2018.html
Lets know how it goes

Hey there When I get into fastboot and run `fastboot devices`, a code returns <tab> fastboot.
... and then the phone restarts I'm trying but I guess I'm beyond the stage of being upset, haha.

Sorry bout d previous link. I believe this shd take u directly to the tutorial:

remember to use "twrp offain for daisy". It works better than the regular twrp for daisy
It my take and procedure that worked for me at the time. Good luck tho
Thanks! Sadly, when I get to the `fastboot oem edl` step, it fails. I get into fastboot, I quickly enter `fastboot oem edl`. CMD says finished, the screen turns off. I immediately refresh in MiFlash (COM3 is the device), I start flashing. After 4 seconds, the device turns off (windows sound "device disconnected"). The flashing runs for a total of 7-9s says "the operation completed successfully.(0x000000000: cmd <?xml version="1.0" ?><data .. etc etc
So I don't really know what to do if I can't get into EDL mode .

Try getting another chord and try again.
Tried some other cables. Every time I run fastboot oem edl, it keeps saying "finished", and then reboots the phone in about 5 seconds. One time, it said "Catastrophic failure" as "status" for the flashing.
Otherwise, it most often says "The operation completed successfully.(0x00000000: cmd <?xml version="1.0"?><data><patch SECTOR_SIZE_IN_BYTES="512" byte_offset="16" filename="DISK" physical_partition_number="0" size_in_bytes="4" start_sector="NUM_DISC_SECTORS-1." value="CRC32(NM_DISK_SECTORS-1.,92)" what="Update"/></data>)
But then still continues in the bootloop...
