Please, help me with saving my device! - OnePlus 6T Questions & Answers

After trying to flash TWRP (by following this guide: https://www.thecustomdroid.com/root-oneplus-6t-guide/ ) my device would no longer boot to the OS,but (stock) recovery and fastboot modes worked, so I tried to fix it by flashing some Android 9 roms from https://forum.xda-developers.com/t/...t-stock-fastboot-roms-for-oneplus-6t.3862516/ , and flashing a stock Android 10 boot.img (for some reason).
But my attemps at fixing it by flashing only made things worse, my current situation is as follows:
Device: Oneplus 6T (6/128)
Version (either Global or T-Mobile): Unsure
OxygenOS Version: Unsure, only know that it is Android 9
Bootloader: Unlocked
- Neither Recovery mode nor TWRP work
- Bootloader and Baseband versions show as empty
- I can only access Fastboot mode and EDL mode
- A power outage left my main pc (which had the drivers, permissions and backup i had been using, and need, to do this) a burning mess
- I´m currently using an old desktop computer i had stored (which has Windows 7), but it fails to recognize my device.
- I have installed and tried multiple versions of the Qualcomm, Oneplus, Adb and Android drivers, but it never recognizes it
- Windows doesnt allow me to manually select the drivers for the Unknown device as ¨the specified folder doesnt contain a software driver compatible with this device¨
- By searching the system and internet it always says that ¨the best software driver for this device is already installed¨
- Both of the above were tried with a disabled driver signature requirement
- When using it on the other PC, the msm download tool, it always said that the image didnt match the device, no matter which of the 13 versions I tried
- On my current PC, the msm download tool doesnt detect my device
I implore anyone that can provide any help or advise to do so, as I´ve already spent an entire week scouring the Internet (including the Oneplus and XDA forums) for any solution, but so far, nothing has worked. Have a good day and thank you for reading my post.

[GUIDE] [UNBRICK] Unbrick Oneplus One

*** I've been receiving many requests and PMs from members asking to help them unbrick their device. Please note that I no longer own this device (and even if I did I would not purposely brick it just to reproduce your problem), therefore I am unable to help out beyond this tutorial. ***
Hello,
First some background and credits:
There are a few ways to brick a phone. Sometimes it's lack of experience, sometimes it's an accidental thing, sometimes there just isn't an explanation for what went wrong... (share your experience here, if you wish). For me, I owned my OPO for about 4 hours before things went wrong. First thing I did was I rooted it and installed TWRP. After creating a nandroid backup of the stock image I installed my favorite custom ROM and restored all my apps with TiBu. Everything was great and configured just the way I wanted it. I then wiped my old phone (Nexus 4), installed a new ROM and got it all ready for my wife. She was so excited to get rid of her GNex and move up to the N4. But then, for whatever reason, I opened an app on my OPO that I used to manage, download, and install kernels with. It came up with "there is a new kernel update!" and I instinctively clicked on "Install". 10 seconds later my phone was bricked. Nothing came on the screen, no fastboot, no recovery, nothing to boot to, no way to send data to and from it. The second the screen went black and the phone became lifeless I got that wretched feeling in my gut as I realized I just flashed a N4 kernel on my new OPO. Restoring the kernel management app with TiBu made it act like it's still running on my old phone, and in my excitement I didn't take a second to think things through...
I received a bit of consolation when a quick XDA search revealed that I am not the only dumbass to brick his phone this very way. I joined forces with some pretty smart and desperate people and tried different things, all described in the following thread: http://forum.xda-developers.com/oneplus-one/help/wrong-kernel-black-screen-fastboot-adb-t2835696. Unfortunately it took us what seemed like many long weeks to figure it all out. Well, in the end a solution was found and I documented it in the the following post: http://forum.xda-developers.com/showpost.php?p=55024864&postcount=136.
This was a few months ago, but I recently noticed many people continue to search for these directions and have problems finding them hidden among many pages and other threads, so I've decided to put this stand alone thread with these, now updated, directions.
Let me get one more thing straight, for the record. I did not find the way to unbrick the OPO. In fact I wasn't even the very first one to do it. It was a collective effort of few people who tried many different approaches and ideas, and I eventually documented these steps for others to follow. Being said, the following people deserve credit as well: @os_man, @rezor92, @Mnt-XDA. If I am forgetting other significant names and efforts, I apologize.
***CAUTION***
The following instructions are for hardware bricked devices ONLY and will not work on soft bricked devices. To determine whether your device is soft or hard bricked, click the button below:
Hardware brick
A hardware bricked OPO has nothing but a black screen (nothing ever comes on the screen, not even a boot logo), it might vibrate when a power button is pressed and held for 20 seconds, has no Recovery partition, no adb mode, and no fastboot partition. The device might be detected in Linux and you might be able to even send commands to it. In Windows, the bricked OPO should be detected as QHSUSB_BULK USB. You might have a bricked OPO as a result of flashing a kernel meant for a different device (or a ROM meant for another device that included a kernel), tinkering with the boot logo or bootloader, or your attempt of unlocking the bootloader resulted in corrupting the boot partition.
Software brick
Please do not attempt to use these directions if your phone is soft bricked. A software bricked OPO is one that might be stuck in a bootloop, but has a working bootloader, recovery partition, fastboot, or adb. If you press the power button and images appear on the screen and you are able to enter fastboot mode (Power + VolUP) or recovery (Power + VolDOWN) then your device is soft bricked. This thread does not encompass soft brick recovery, the instructions below do not apply and will not work on these phones. Consult other threads for help on soft bricked devices.
If based on the above explanation of differences between soft and hard bricks you determined your device is hard bricked, here's what you will need to do...
1:
Download Color.zip from (mirror needed).
After downloading, unzip the archive on your computer.
2:
Next, you need proper Windows drivers. There are architectural differences between Windows XP and Windows 7/8, so follow the directions below that pertain to you. One quick note about the drivers: the installation and process is very simple and straightforward on Windows XP (I also tested successfully on Windows 2003), but proves to be quite a challenge when running on Windows 7 or 8. Over and over people report issues when attempting the unbrick procedure on Windows 7/8, some have more luck than others. Being said, if you have access to a Windows XP computer, I highly recommend that you use that. If you have no choice but to use a Windows 7 or 8 computer and have problems, please share them here and read others' experiences.
So first, by now you probably tried a few different things to fix your phone and you've already installed some drivers, including Qualcomm USB drivers for 9006 and 9008. My best advice is to uninstall the drivers you tried so far and use the ones listed below. Go to Device Manager, right click on the bricked USB device (QHSUSB_BULK or Qualcomm HS-USB QDLoader 9008) and go to Properties, click on Driver, then select Uninstall. Check the box to remove driver files, if prompted. Then:
2a:
Windows XP users:
You are in luck, driver installation is straightforward. Go to the extracted Color.zip folder and find Driver.iso. Extract Driver.iso. Inside the extracted folder find Setup.exe. Run Setup.exe to install the drivers. The installer is Chinese, but all you need to do is click through the prompts.
2b:
Windows 7 and Windows 8:
These operating systems block unsigned driver installations by default. Follow these steps (thanks @nag4pl for testing these):
Download and extract these Qualcomm 2012 drivers: (mirror needed).
Connect your bricked phone and let Windows do its thing.
Now something very essential you need to do here is to execute two commands to allow you to install unsigned drivers for QHUSB_BULK. Click on Start Menu > Type cmd.exe > Right Click and Run as Administrator.
In the CMD window type in the following commands (hit enter after each):
Code:
bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS
Code:
bcdedit.exe -set TESTSIGNING ON
After both the commands should run successfully, restart your computer.
You can now proceed to install unsigned drivers from the file you downloaded. Open Device Manager, you should be seeing ugly yellow warning under other devices for QHUSB_BULK. Right click on the name and select Update Driver Software > Browse my Computer for driver software. For driver software location provide the path where you have extracted Qualcomm 2012 drivers you downloaded and make sure 'Include Subfolders' is checked. Proceed through all the installation prompts ignoring any warnings.
3:
Once you have the drivers straightened out, connect your bricked phone to the computer and start it up by holding VolUp + Power to about 10 seconds, and let the computer do its thing. Don't install drivers if they are not installed by itself. Instead launch Msm8974DownloadTool.exe as Administrator (right click on Msm8974DownloadTool.exe and select "Run as administrator") from the extracted Color.zip archive. It will scan all the COM ports and find the phone. That's the one line that looks different in the list. The list is just a list of your com ports and devices. If you unplug the phone and move it to another port, it will show your bricked phone on a different line.
Clicking on "Enum" just rescans the busses. Clicking the big square button in upper right corner scans the phone and reports what's good and what's not. It takes a minute for the scan to finish.
If you don't see your phone in the list of com devices, try unplugging/plugging in your phone a couple times, and rebooting it with VolUP + Power (hold 10 seconds). You will see it in Device Manager as well.
Once you see the phone in the list, click Start. You should see the programs start writing different files to the phone. Each time it writes a file you'll see a progress bar. Once you see this process happening, smile, you know you will be good to go... After all files are written, the com line with your device will turn green. You're good, unplug and reboot your phone. It will boot to ColorOS, the Chinese OS that comes on OPO.
4:
Optional Steps:
Your phone is no longer bricked. You now have a few options to get back to stock. The easiest way is to use a toolkit from http://forum.xda-developers.com/oneplus-one/development/oneplus-one-toolkit-manudroid19-gui-t2807418, or you can flash an image manually by following directions from: http://forum.xda-developers.com/oneplus-one/general/guide-return-opo-to-100-stock-t2826541. Download the proper image zip and after extracting it, run the following commands in fastboot mode:
Code:
fastboot flash boot boot.img
fastboot flash userdata userdata.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash cache cache.img
fastboot flash modem NON-HLOS.bin
fastboot flash sbl1 sbl1.mbn
fastboot flash dbi sdi.mbn
fastboot flash aboot emmc_appsboot.mbn
fastboot flash rpm rpm.mbn
fastboot flash tz tz.mbn
fastboot flash LOGO logo.bin
Make sure you have the proper image. I accidentally installed the 16GB version on my 64GB OPO first time and obviously didn't get 64GB of space.
That's about it. I think if people are still having problems then it's likely due to drivers, or Windows 7/8 issue.
Good luck! Share your experience here and let me know if I can improve this thread.

You should be able to boot to fastboot now. From there flash the cm11s image. I believe that "fastboot flash sbl1 sbl1.mbn" will fix the imei issue.
Also, unlocking bootloader does not void your warranty. Not with OPO.

Just to give one last try, flash color os modded zip from relic, i used 2.0.43 purezip and it gave me back my imei. Had the same issue as you last week. Be sure to flash TWRP 2.8.4.1 first and then flash color os.
Legit method.
Worked for me 2 weeks ago!
unbrick oneplus one, oppo 7
Hi there my friend, i had many works about unbricking solutions, a few of you know that, i have much easier and faster ways now, tested many times before i decided to share with you, it will be a long topic ( and my brain is messed up to sum them up clearly), as soon i can think clearly again, i start to write them, till then,
greetings from Istanbul to all geeks around thw world.
Ps: including restoring imei's if they got lost during this process.
Ps2: just a quick info abou imei, if your imei is "invalid" , this means your modem.bin (NON-HLOS.bin, baseband) is not inadaptable with your rom, just try flashing the right modem ( from fastboot), your imei will be back.
Ps3 : This will lead us to unbrick many Snapdragon's out there , not only oneplus one's or oppo's.
I had to use this tutorial some days ago.
There is also a modified .zip where the tool from OPO flashed CM11s instead of ColorOS.
http://forum.xda-developers.com/oneplus-one/general/tool-oneplusrecovery-tool-v1-0-restore-t2991851
I had many driver problems and i had to use this driver from qualcomm so my win7 could recognize the phone.
Tutorial to install the driver:
1. Open your device manager (Start - right click on computer - properties - devices manager)
2. Press on power + vol up for like 10 sec until you see a device showing up (called QHSUSB_BULK)
3. Right click on this devices and click on "Update Driver Software" -> "Browse my computer for driver software" -> locate the Qualcomm 2012\fre\Windows7 8 or vista folder depending on your setup. Update the driver.

Back from Brick!!
First of all Thanks a lot to @netbuzz(for such a life saver guide on unbricking 1+1) and @michaeldepotter for providing link to download appropriate drivers.
Here is some good news by my findings and can be a quick help for those who do not have or can't get XP. You can use Windows 7 itself for the process mentioned by @netbuzz
All you need to do is:
1. Download drivers from link provided by @michaeldepotter : https://www.dropbox.com/s/vgujdut93m341qm/Qualcomm 2012.rar?dl=0
2. Extract to some folder under C: or whichever drive you prefer.
3. Connect your bricked phone after pressing Volume Up and Power key (make sure phone vibrates once)
4. Now that QHUSB_BULK should be detected and Windows will eventually try to download drivers from update, which you can skip and close the window.
Now something very essential you need to do here is to execute some commands so that you will be able to install unsigned drivers for QHUSB_BULK.
4a. Click On Start Menu > Type cmd.exe > Right Click and Run as Administrator (make sure you are running cmd as admin)
4b. Now type below command
bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS
>hit Enter
bcdedit.exe -set TESTSIGNING ON
> hit Enter again
4c. Both the commands should run successfully, then restart your computer.
These steps are to disable driver sign verification. You must proceed to next steps only after above steps executed successfully.
After machine booted back to desktop
5. Now Open Device Manager by Start > Run > type "devmgmt.msc" and hit enter
6. You should be seeing ugly yellow warning under other devices for QHUSB_BULK.
7. Right click on the same > Update Driver Software > Browse my Computer for driver software
8. Now under driver software location, provide the path where you have extracted drivers which you downloaded from step 1. For me it was:
"C:\Users\Arjun\Downloads\Qualcomm 2012\fre\Windows7" - Remember to provide path only till windows 7 and make sure 'Include Subfolders' is checked.
9. Click next, and it should install driver for QHUSB_BULK. Click on Install Driver if you get any warnings.
Now your driver set-up for QHUSB_BULK in Windows 7 is complete and now you may proceed with the steps to run Msm8974DownloadTool as provided by netbuzz.
I have attached the screenshots for the same just for confirmation.
SuccessfullDriver - showing successful installation of driver
FlashInProgress - showing tool flashing the system image
FlashSuccess - showing green row indicating successful flash.
Once again, thanks a lot for all the guide and help. Hope this quick guide helps some one in need!!

Thanks for this Win7/8 workaround. I'll be adding your info to the OP.
Finally Unbricked mine...Drivers resolved on Win 7
netbuzz said:
Second note about drivers is that I had the worst time trying to get things to work on my Windows 7 computers. Both Windows 7 and 8 block unsigned driver installations by default. I've tried overwriting these settings in Windows and spent half a day messing with it, and I never got things to work properly. At first all looked good to go, but then latter steps were failing. You might have a better luck getting drivers to work on Windows 7 or 8 (I've heard some people did it), but if you have access to a Windows XP or 2003 machine, try it first, it should save you some major headache.
Once you have the drivers straightened out, connect your bricked phone to the computer and start it up by holding VolUp + Power to about 10 seconds, and let the computer do its thing. Don't install drivers if they are not installed by itself. Instead launch Msm8974DownloadTool.exe from the extracted Color.zip archive. It will scan all the COM ports and find the phone. That's the one line that looks different in the list. The list is just a list of your com ports and devices. If you unplug the phone and move it to another port, it will show your bricked phone on a different line.

I have used the override tool for certificates: DSEO - Driver signature enforcement overrider
to allow the unsigned drivers to be used and it worked like charm on windows 7 64 bit.
Also, I used the additional Qualcomm 2012 drivers and not sure which one might got picked in that mess :cyclops::cyclops:
Thanks!!
:good::good::angel::angel:
nevermind!
Well I managed to hardbrick my phone. I am download the ColorOS file from Mega at the moment. It's downloading at 30KB/s and will take around 6.5 hours. Is there any other source to download it from ? Thanks !
Also, about the driver ...
While I wait on the colorOS to download I want to clarify one more thing about the driver.
According to the screenshot of @nag4pl the driver should show as Qualcomm USB diagnostic 9006, while for me it shows as Qualcomm HS-USB QDloader 9008. Is this going to be an issue ?
This is what I did. I uninstalled the default driver that came with windows 7. After that it failed to install the driver provided in this forum because it kept saying that device descriptor failed. I rebooted the phone several times and changed the USB ports and eventually windows detected it but AGAIN with the windows driver even though I had checked the option to delete the original driver while uninstalling it. Through the update driver option I managed to force it to install the unsigned driver.
Now I can see both the drivers under the update drivers option. Interestingly the default driver is a version ahead of the unsigned driver provided in this forum.
My only concern is that I see a different driver name compared to the one posted by @nag4pl
Thanks! Very useful for me!
That shouldn't be a problem. Not sure if that is specific to region, mine is India version phone.. Can some one clarify on this?

[TIP] Problems with LGUP, LgFlashTool 1.8 or 2014, LGMobileSupportTool? Try LG Bridge

I've spent hours today trying to fix my LG G4 after things went south. Here's what happened:
Unlocked bootloader
Flashed TWRP
Tried to flash an AOSP ROM
Flash SuperSU, breaking boot
Had issues with PC driver disconnecting
Reinstalled various driver versions
Tried flashing KDZ, Nope.
Tried flashing an AOSP/CM ROM, Nope.
Flashed 'recovery.img' from http://downloads.codefi.re/autoprime/LG/LG_G4/H815/H81520G/, thinking it would restore normal LG recovery.
YEAH, THAT DIDN'T WORK. Now I have no recovery at all.
Switching drivers means I now have no adb/fastboot access - UHOH!
So I spent the next THREE HOURS trying to simply restore a KDZ. Here's what didn't work:
LG's Mobile Support Tool - just tells me I have the latest update
LGUP - 'Unknown model' - and no root access to fake a model number in 'build.prop'
LGFlashTool 1.8 (with MegaLock.dll) - This probably would have saved me, but I could find a _single_ TOT+DLL combo for my H815, even though there were MANY references to downloads of them at http://storagecow.eu/index.php?dir=Xda/LG+G4/H815/
LGFlashTool 2014 - Every time it loaded up I got a useless 'Could not find required info' message.
LG_Root package - DESPERATION. The Send_Command tool is able to send commands over a specified COM port. This got me a on-device shell, but I couldn't think of anything useful that would help. In 'Download' mode, IP and all kinds of things dont seem to work.
And when I thought all was lost, I tried installing LG Bridge. Here's what got me up and running again:
Install LG Bridge
Connect device in Download mode. FYI: 1) Unplug 2) Reinsert battery 3) SIMULTANEOUSLY hold down VOLUP and insert USB
Open LG Bridge
Choose 'Update error recovery' in the bottom right corner (blue text)
The app will: 1) Prepare device 2) Download the latest software 3) Reinstall it
Unbelievably, that worked for me, after wasting hours reading responses on this forum.
XDA-developers needs a WIKI to centralise information. Thousands of hours could be saved.

Oneplus 5 trouble with unlocking bootloader and TWRP

Hello this is my first post. I have searched the threads and internet for answers but I have not been able to find a solution.
I have been customizing my phones since the days of baked black bean on my galaxy S1, but I am no expert at this stuff. Until about a week ago, I was happily running RR on the OPO (great ROM) but it has gotten a bit slow so I figured it was time to get a OP5.
When I boot into fastboot, my device is recognized with the command fastboot devices. My phone showed the following:
fastboot mode
product_name - QC_Refernce_Phone
VARIANT - MSM UFS
BOOTLOADER VERSION -
BASEBAND VERSION -
SERIAL NUMBER - c7ccda2
SECURE BOOT - yes
DEVICE STATE - locked
When I ran fastboot oem unlock, CMD prompt shows FAILED, however, the option to unlock the bootloader shows up on the OP5. I go through the process and wipe data. My phone now shows that it is unlocked, and I go into developer options to get advanced reboot/USB debugging/verify OEM unlock is still enabled. When I go back to fastboot, I am unable to flash TWRP. I have now seen a number of errors, usually:
FAILED (remote: Requested download size is more than max allowed) or target did not report max download size, or command write failed (no error). I have tried installing 4 different versions of ADB/fastboot from different sources, and I have tried TWRP cheeseburger 46, 58, and 62. I have also tried two different USB ports and 4 different USB drivers.
Does anyone know what could cause these issues or how to get TWRP installed? Any help would be much appreciated. I really want to get rooted and get substratum running.
hmm
did you type fastboot devices to check that u got connection ? do you have another pc to try ? another usb port
edit: also try disable developer option and aplly it again with oem unlock tapp
EDIT2: if you cant still get it work you can try
Advanced settings -> Backup & reset -> Reset all settings and after that unlock bootloader
I was able to solve this by using a friend's laptop and installing the drivers and abd. Worked like a charm and I was able to flash magisk for root.
For anyone else having this issue, try another pc if you can. I'm guessing this was either an issue with adb on my machine or a problem with the device drivers.
bro do u find solutions for this
I found an actual fix for this problem. Basically I had to download Large Address Allocation Tool (LAA) which you can find online. I would link to it but I do not have the website handy.
I found this solution after soft bricking my phone by installing Oreo (I don't suggest using VPN to pretend you are in Canada. Just run the beta or wait for the US release).
Essentially, you just need to run this tool on your adb.exe. From what I understand, the issue is just that adb is not using enough RAM. I think you'll need to be running Windows 7 64bit with at least 4GB RAM. I hope this info can help someone else!

Ever since i ditched windows and went with ubuntu i have not had one single driver issue, not one single hiccup on anything. It's been two months.. I'm never going back. lol. Every time I use adb and or fastboot it always works.

Unable to hack Asus Zenfone Laser 2 [ZE550KL - Z00L - Z00LD]

Hi to all.
I landed on XDA because I am not able to hack my Asus Zenfone Laser 2 dual-sim (ZE550KL, which seems to be also called as Z00L or Z00LD... I don't know why... ?!? ). Actually I'm very new on smartphone hacking, so I did my best recently to understand what "rooting", "recovery", "brick" etc mean.
I tried to enter this world because my phone gets gradually very slow as I use it and so I supposed that erasing the pre-installed applications and overclocking it would help, possibly installing a lighter and more performing custom rom. In order to do this I read that in short I have to unlock the boot loader, root the phone and then eventually install a custom rom. In fact I suppose that getting root privileges should already do the job by keeping the original rom, unistall all unwanted apps and eventually overclocking it. Is that correct?
However, the problems I found on my way are the following two:
I've not been able to follow those procedures on Linux. In detail, I'm not able to use "fastboot boot" instruction because it gets stuck on "waiting for any device". The device is listed and allowed when running "adb devices", the boot had been unlocked previously, the phone is in debug mode etc... but the problem is still there despite I've been trying with both the adb package included in the repositries and the one downloaded from the related google page. I've been told it may be a matter of USB drivers, so I also installed the android studio package thinking it would help, but I was wrong. I'm quite confused on this, despite I do hope I can hack my phone using my favourite operating system (I'm a Linux user since 2006). If you do not feel like helping on this then I will try on Windows.
After trying the same procedures on Windows 10, I realised that the Android Usb drivers released by Google did not work. I had to install the proprietary ASUS USB Drivers from the official website and only then I was able to overcome on Windows the same "waiting for any device" I had experienced on Linux. However, the phone "bricks". I suppose this should be the technical term used in this field to tell that the phone gets stuck for hours on the boot animation. I tried several times to reboot it, but each time the same story.
Maybe the problem on Linux is that I do not have the proper Android Device Usb drivers installed. In this case, how to solve the problem taking into account that ASUS only released the drivers for Windows?
RECAP: I have my phone bricked now (Android is unable to reboot, but I can do access both to the Power+VolumeUP menu (by the way, what's the name of this menu? Fast boot?) and the Power+VolumeDOWN menu (by the way, what's the name of this menu? Recovery boot?)
So sorry for the long story.
Hope you can help.
Thanks for your attention and best regards.
Uhm... no replies till now?
i dont know how you get this kind of trouble, maybe try other computer? , im using wondows 10, download small package of of fastboot driver and adb driver, flash twrp using fastboot command. all done. then i make full backup using twrp, next flash magisk .now i have root access, any problem or bootloop i just restore the full backup that work.

i see a lot of this zen2 laser got bricked on this general forum , you should read some more if that could help
When I had this device, I remember booting a temporary recovery TWRP and rooted it in that recovery. Then once I got rooted, I installed TWRP app and installed a permanent recovery from within the TWRP app, which needed root of course. Then I got everything working.
You can try booting on a temporary TWRP using fastboot then flash supersu or magisk or whatever rooting client you want. Though, I think you need an unlocked bootloader. I'm sure there's a guide around here somewhere
I'm using a Z00T and just installed LineageOS yesterday using Windows 10, following a guide by Android Authority and LineageOS.
Volume Up + Power = Fastboot
Volume Down + Power = Recovery
Sounds like you can get into Fastboot, so I'm wondering if maybe you can use it to flash the recovery image??? (I'm not a dev in any form; try this at own risk)
I'm assuming you unlocked the bootloader already...
In the directory where all your images are, perhaps try flashing the recovery with the following, where RECOVERY.img is whatever you may have renamed the TWRP image to be:
Code:
fastboot flash recovery RECOVERY.img
After it's finished flashing, turn off the phone, then reboot into recovery mode with Volume Down + Power.
Something Similar happened with my phone and looking for answer
Hi All,
I'm new to this but do some hands on reading these forums. Recently i don't know how but my phone continuously boot into Fast-Boot mode. If I try to push some zip file as mentioned i'm getting error related to partition. "failed to write partition."
Can someone help me out with this.
Thank in advance.

I'm using Z00T and Windows 10. Had no issues using the Android Authority and LineageOS guides.
These guides are great but I don't want to lose my data by formatting my bootlooping device, and the drivers asus gives do not work with windows 10, the adb drivers work fine but the asus drivers do not.

(SOLVED) Urgent ! My OP8P is dead I think, stuck Fastboot

Hello everyone !
I'm new on this forum but I really need your help. I tried to fix my mistake all day long yesterday (9am to 2am non stop).
So, basically, I have a OnePlus 8 Pro, Model IN2023.
I had OOS 11 updated. I tried to install OOS 12 Bêta and I did but I had a indian version so a lot of bugs.
I wanted to go back to OOS 11 but it was impossible because I was now in an indian version.
I tried with MyApplication2 to local upgrade and downgrade as recommand in Internet.
I tried to unlock bootloader and the following steps but here my problem:
I unlocked my bootloader then I misclick and I locked again my bootloader.
Then my phone just crashed and put this message:
"The current image (boot/recovery) have been destroyed and can not boot."
So, I forced to turn off the phone and try to go in EDL mode but:
1. ADB doesn't work anymore
2. Fastboot work fine
3. EDL mode is impossible
So, my bootloader is unlocked again. My phone is stuck on Fastboot mode:
Fastboot mode
Product_name - kona
Variant - SM8 UFS
Bootloader version -
Baseband version -
Serial number - eed52b71
Secure boot - yes
Device state - unlocked
I used the official firmware on OnePlus website, I used Python and Payload_dumper.py to have the .img from the .bin of the official firmware.
I tried to flash all the images, I tried to install TWRP, I tried almost everything I found but still stuck in Fastboot. Recovery mode doesn't work.
I tried to boot, to flash, to do everything I could.
I also tried MSM Download Tool but nothing appears inside.
Now, when I connect my phone, it's with a cable in USB-C but 3.0, not 2.0. Maybe that's the problem ?
When I plug my phone, in Device Manager, I have a "!" but the phone is recognized under
"Qualcomm HS-USB QDLoader 9008 (COM6). When I click on it, it says (sorry, I'm about to translate from french):
"Windows can not verify the numeric signature for the drives required for this peripheric. It is possible that a material ou software modification has been installed a corrupted file or with an incorrect signature, or it is a malware from an unknown source (Code 52)"
Please help me, contact me on Whatsapp, or here. Let's do this in direct.
Btw, I have a Macbook Pro to do all this. I used also Windows with Bootcamp.
So... I finally did it. 2 days to do it.
I asked a friend to lend his computer (Windows).
So my phone turned into EDL Mode immediatly without trying to do so.
I plugged into my MacBook under Windows (Bootcamp) and launch MSM Download Tool under an old version and it worked.
I tried first with the latest but I had "param preload failed" so I found a good article MAGIC and tada.
SUCCESS. My OnePlus 8 Pro works better than never.
Don't install OxygenOS 12, it's really bad.
