Adb not working under fastboot mode

Trying to flash twrp in fastboot mode, but not having much success. Adb devices doesn't list my device and when i try fastboot flash recovery it says that it's written something but when i try to go to recovery mode after reboot it just takes me to the stock recovery which resets the phone.
Have latest lg drivers along with 15 second adb installer installed. Running win 10 x64.
Any idea how i can successfully install twrp?
Thanks

Yea just read the main XDA twrp thread carefully! You did it wrong and its all there.
And fastboot is not adb! In fastboot mode you can't use adb

Ok read through it, inc a couple of guides mentioned in that thread. Rebooted to bootloader no problem
However when i type fastboot boot twrp.img i get the error:
FAILED (remote dtb not found)
typing fastboot flash twrp.img is down as successful but when i try to boot recovery it just takes me to the stock recovery reset.
All fastboot and lg drivers installed.

No there is only one official twrp thread (see my signature) and there is only one guide to flash.
Try fastboot boot but with version 3.0.2.0 instead

That's the guide i was following. Still get same error when issuing command. Think it's to do with the drivers in win 10 under fastboot mode.
Had an explanation mark against android. I selected update driver and then adb bootloader interface from the list.

maybe problem is not on the driver but haw to write comand, use this ( flash recovery twrp-2.8.x.x-xxx.img ) or ( fastboot flash recovery twrp-2.8.x.x-xxx.img ). use and this twrp 2.8.... if the problem is on the driver's use this link http://www.guideitech.com/mobile/android/risolvere-errore-waiting-for-device-android-adb-fastboot/ this section adb kill-server adb start-server

if you wanna be sure that this is not a driver issue just try FWUL
but back to your problem. This error can happen when u have a older/newer bootloader flashed which works in another way as it should.
What is your current ROM version?

most ppl are on MM or N these days which has a newer bootloader.
This should solve your problem.
otherwise just try all TWRP versions you find - from high to lowest version. hope u will find a working one for LL.

Ok, I can boot TWRP using fastboot boot twrp-3.0.2-1-h815.img. However when I try to flash it I get the following error:

Good so it is actually a bootloader thing. Please read the official twrp thread (see my signature) and find the installation guide. The behavior above is expected and there is a way to solve. Just read carefully.

Ok, so followed the guide from https://forum.xda-developers.com/g4/development/recovery-twrp-3-touch-recovery-t3442424 (which was in your signature)
Installation
General Howto Guide
The general guide seems to do not work properly when it comes to flashing so here is an additional howto which seems to work 100%:
I said you need an unlocked device. So ensure you have it unlocked and OEM unlocking option is enabled (see screenshot)
Connect an USB cable and get ADB running (READ the FAQ!! or the general guide above)
Boot into Android and then type on your PC to reboot into fastboot mode:
adb reboot bootloader
Type on your PC:
fastboot boot twrp.img
(replace twrp.img with the real file name you downloaded)
Then copy the twrp.img to your device while still in twrp (e.g. with a file explorer or by typing adb push twrp.img /sdcard)
Flash the twrp.img with twrp GUI to the recovery partition (choose the button at the bottom named image to show the copied image)
done.
You can now reboot into recovery again to check it has worked.
However, despite booting into twrp ok and flashing the recovery ok (according to twrp), when i restart the phone and go to recovery it's the stock recovery, not twrp.

ok. do the same again but when you have flashed twrp from within TWRP grab the recovery log (like described in FAQ #4-A)
hope we get some meaningful information.. because this really should work.

Reboot to recovery worked within the booted twrp, just not when I turn the device off and try to enter recovery from the hardware keys. Using hardware keys and selecting Yes twice just took me to stock recovery which does a factory reset and wipes device.
Didn't try adb reboot recovery.

Volume down and power button together. Release power button for a second when LG logo appears and then press and hold it again until reset screen appears. Usually from there i select yes and yes again and twrp would appear (when it was working)

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

Download Universal ADB software, download the latest version and install it.
TWRP 3.0.4-1
Official Oxygen OS 4.0.3

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
fastboot devices
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.

Forgot pattern on Android 10 Beta

Hello everyone,
I have managed to forget my pattern. :crying: I'm on a Pixel 1 and on Android 10 Beta 4. The problem is I have my bitcoin wallet on that device, which is the reason why I cannot factory reset it.
The problem is I cannot reach the device via Google Find, even though it's connected to my WiFi. I also tried putting in a simcard - this didn't help either. Next problem is, I cannot access it via ADB, only via fastboot in bootloader mode.
Any ideas what else I could try? I'm starting to give up...
Best regards

Thanks for your post friend, but, your guide doesn't fulfill my situation.
As, I am stuck on bootliader or boot logo.
I have flashed all firmwares s048,s233,s244,s51 through fastboot but none of them able to get me out of it.
Even tried flashing various recoveries both stock and twrp but neither of them helped
If, anyhow I can be able to enter into TWRP. It will solve the problem. But, I don't know nothing seems to work.
Even tried corrupting the bootloader and then flashing blankflash, but that too didn't able to get me out of the bootlogo.
Please help ?

Yep. Go ahead. You can try S244 firmware to try and boot your phone. If it boots then update accordingly as I mentioned in my guide.

Still no luck! :crying: flashed S244 several times but nothing.
Can you confirm one more thing.
When I give
"Fastboot format system" I get :
"Formatting is not supported for file system with type 'raw'."
screenshot attached. Please check

I have checked the text file of your guide, and they are the same instructions which I have been following since start. :silly:
The "fastboot format system" is a command which I used to do on my Moto G, and was able to format system successfully.
But, I don't remember if it used to work on P2 or not , that's why I asked you. If, you can use that command to check the output on your device.
Thanks

Hmmm so you haven't read .txt file carefully. Command is:
Fastboot ERASE system
See the difference now? :silly:
Please, discuss it on that thread if need so others could also benefit from it.

OMG, yes brother, I already know the command, and I have used it several times, the fastboot ERASE command, but, as mentioned several timesin the past, it is not solving my problem.
As, I am still not able to enter into any recovery(neither stock nor twrp), and not able to boot and OS.
That's why, I wanna try "Fastboot format system" command.
If, somehow that solves my problem

OK. I though that you only tried Format command not erase. You should skip this command and do the whole process. I have added this command so that previous system files are erased. But, I booted my phone without using this command first time. Second time, I tried to see if I can do it all in a single process then I added this command and it worked without any issues and all the process went smooth and phone booted like a new one.
Try all commands but skip erase system command.

stuck on logo , have access to fastboot only
My phone stuck on logo when i open it or when i insert charger
when i try to open recovery(volume up + down) it turned off and i can't open recovery by any way
i can access fastboot
i tried your instruction and Lenovo+P2+UnBrick+OneTeam-EypCnn and all other fastboot roms
i tried install Twrp and stock recovery
i tried blankflash
that didn't help ,i can only access fastboot
what is your recommendation ? it's a hardware issue ?

fastboot erase system
fastboot format:ext4 system
Maybe related to the file system ?

Unable to Install any TWRP Image on my Nokia 6.1 (2018) - Getting Stuck on Splash Screen

Hi Team,
I have an spare Nokia 6.1 (2018) smartphone (Model # - TA -1089)) at my home which I wasn't using since 2-3 years.
Today, I got hands on it, and tried to use it for my development needs.
To begin with, I unlocked its boot-loader using this guide to unlock Nokia 6.1 (2018)
and within "Developer Options", I can see that the "OEM Unlocking" option reads - "Bootloader is already unlocked."
Now, as a next step, I am trying to install TWRP recovery, but nothing seems to be working. No matter which image I try, I get stuck on the TWRP splash screen.
I have tried TWRP Images from the following websites and many more:
TWRP.me
Get Droid Tips - Here when I click on the "Download" option, I get redirected to the "TWRP.me" website only, whose images are not working.
In addition, I have ensured that "ADB and Fastboot" + "Nokia USB Drivers" & other contingencies are properly installed on my system & are not the underlying issue.
I tried running the code
Code:
fastboot flash recovery twrp.img
and my phone got stuck on the TWRP splash screen. Ultimately, I had to use OSA tool and flash the STOCK ROM to get my device working again.
Many websites suggested to simply boot the TWRP and so I used this command:
Code:
fastboot boot twrp.img
in the "Download" mode and then again, nothing happened and I got stuck on the TWRP splash screen.
Note: The only difference between above two commands being - my stock recovery worked fine after executing the 2nd command, and I could boot into my device without much trouble.
Here's my Device Overview:
Device Name - Nokia 6.1
Model & hardware = TA-1089
OS version - Android 10
Security Patch Level - May 1, 2020
Build Number - 00WW_4_15c
Can someone now please suggest where I could be going wrong?
What's my goal:
Root Nokia 6.1 & to be able to install Custom ROM's on Nokia 6.1 and use that device for development purposes
and in case anything goes wrong,
Flash the STOCK ROM again using OSA Tool and bring the device back to its current state.

Hi @White_devil_04200
Thank you for redirecting me to this Telegram channel.
However, let me share that - On the channel, I found "twrp-3.3.1-1-PL2.img" listed as the TWRP image that works.
The conflict is that - I downloaded this version only from multiple sites & after flashing it, got stuck on TWRP splash screen. I had to use OSA tool to reflash Android OS & restore the stock recovery.
And, when I ran the code -
Code:
fastboot boot twrp.img
, then also I got stuck on the splash screen, but was able to reboot into the OS successfully.
Note: Also, I tried switching the slots too (from 'a' to 'b' or vice versa') but then also, nothing worked for me.
I hope you get my problem, and would now assist me accordingly.

this is how i use twrp on nokia 6 2018 (since i unlocked it):
1. connect my phone with download mode to my pc:
2. run 2 code lines:
fastboot flash recovery twrp.img
fastboot boot twrp.img
3. and done.
The only disadvantage of this way is that every time I go to twrp, I have to run those 2 code lines with my pc. Still, it worked (at least for me).
You can try my twrp version.

Thanks @Bảo Dora for sharing your TWRP file and for the instructions.
I was finally able to boot into TWRP (used another file, of course), and then successfully get "root" access on my device.
Also, I read that if you execute the command:
fastboot flash recovery twrp.img
Click to expand...
Click to collapse
you shall permanently install TWRP on your device, which may or may not be the first preference of many users.
Having said that, am glad that it worked out for you. However, I still prefer to use just the "boot" command to avoid changing my stock recovery.
Thanks for your help again.
Cheers,
Manu

For potential readers of this thread, I would like to explain one thing here.
"fastboot flash recovery twrp.img" does NOT change your stock recovery on Nokia 6.1. Because this phone has "A/B system updates" and due to that the recovery RAM disk is now contained in the boot.img file. So Nokia 6.1 has not recovery partition so if you execute the "fastboot flash recovery twrp.img" command it only shows an error message and nothing is changed on your device.
Common issue on Nokia 6.1 is that when you execute only this one command "fastboot boot twrp.img" then it stucks on androidone logo.
But for some special reason, if you execute "fastboot flash recovery twrp.img" and then "fastboot boot twrp.img" it successfully boots into TWRP recovery.
Really there is nothing to worry about. This procedure is safe and really works.

Let me try and find that file link again bro. It's been time I performed the root process, so I will have to search for it.
Will share it with you at the earliest.
Till then, stay calm and be safe.

Hello,

I successfully unlocked the device.
When i do to 'fastboot boot twrp.img' in 8 of 10 cases it stucks on Android One screen but sometimes it stucks at twrp boot screen.
I have tried multible twrp versions for Nokia 6.1 PL2.
I also tried 'fastboot flash recovery twrp.img' but here comes a adb error that says:
Sending 'recovery' (38592 KB) OKAY [ 1.064s]
Writing 'recovery' FAILED (remote: '(recovery_a) No such partition')
fastboot: error: Command failed
On Galaxy S6 this works fine for installing permanently but here i event cant boot into twrb.
