Stuck in Fastboot Mode after flashing stock ROM - OnePlus 8 Pro Questions & Answers

Hey,
I got a real problem with my OP8 Pro.
I was running Android 11 Beta on my OP8 Pro, with an unlocked bootloader.
For some reason, I would liked to go back to stable Android version.
So, I download this ROM 11.0.0-EUROPE-OnePlus8ProOxygen_15.E.30_OTA_0300_all_2009301818_f85a40a8ec66246-FASTBOOT and flash it using the .bat file in it.
After flashing, my OP8 Pro reboot and I'm stuck in FastBoot Mode....
What I have already tried :
Start : reboot in FastBoot Mode
Restart Bootloader : simply restart in FastBoot Mode
Recovery Mode : I can access recovery mode and I tried tp wipe system settings, cache and user data, then it reboot in FastBoot Mode
Power off : let the phone off for 1/2 minutes, but it reboot FastBoot Mode after
Re-flash the same ROM : always stuck in FastBoot Mode
Actually, I don't know what to do...
Could you help me please? Thanks

hello freinds
i have a big problem , i tried to make factory rest that used in wm6.5 (vloum down + power ) but to the android
and after that the phone always boot to fastboot mode even i cant get the recovery mode , i tried to install wm6.5 but it also stuck on the fastboot , and also i tried many bootloader like mr schould or mr menjami boot loader but it gives the same error ,
notice: just when i install the lk bootloader of menjumi i can access the recovery mode and i install the android rom and when reboot it stuck on the same error and i have to instal the recovery again to get into it
this is the errors
press VOLUME UP for RECOVERY
press VOLUME DOWN for FASTBOOT
flash read image :failed 319 errors
ERROR: cannot read recovery header
ERROR:cant read the kernel image
ERROR: could not do normal boot. Reverting to fastboot mode.
ENTERING FASTBOOT MODE
udc_start()
please help me to fix my hd mini ,
Abdulla, this is very normal, just do it again!! I mean reinstall the Recovery, do twice time.
This is because the Recovery hasn't been installed fully, and no Android ROM installed (or corrupted), so this will happen any time if that.
and also, you did factory reset for WM6.5 and this will erase all of them.
Don't worry, this doesn't mean phone bricked

oneplus 2 reboot loop

hello,
i try this afternoon to unlock the bootloader from my OP2.
and when i did fastboot reboot my OP2 is in reboot loop mode.
i can't do nothing my phone.
can someone help me?
flash twrp,flash rom
Hi,
I have same problem
but if you want to start phone you can use: fastboot continue comand in fastboot mod.
.
Had a similar thing. Hold vol-down + power to boot into the OP recovery. From there you can wipe data and cache, sortof like in TWRP. It should boot then. Anyway, worked for me.
This has happening to me as well. So happy this was just me, not that this is a good thing, but I was freaking out.

Use fastboot continue to enter the mobile system..
Download Oneplus2 stock rom from oneplus forums....
Use flashify to install the same into boot rom... (Leave data option unchecked or better still backup your data for safety.....)
The issue gets resolved and you will have the virgin Oneplus2
You can then enter recovery mode...
Make sure you install TWRP or other recovery after you intall the stock rom ....
Hope it works for you... It did for me .....

Stuck on LOGO while going into Recovery Mode

I successfully Flashed Recovery using FastBoot but whenever I am going into recovery mode by pressing VOL DOWN+POWER it just shows OnePlus LOGO and nothing happens after it.
What should I do ?
I was using CW 13 with TWRP but then I FLASHED OXYGEN OS 3.0 and cleared the cache. After that, It is loading into OXYGEN but there is no developer options over there and it is not even going in recovery mode now.
HELP!

try this method. I tried and solved the problem.
Boot your phone into fastboot and on your pc, try 'fatboot oem device-info'
If it's locked, you're as ****ed as I was, my thread here.
(
You will have to go with Bhalla's unbrick guide
Tutorial on how to still get into your OS and save your stuff is in my thread - fastboot continue
)
If your bootloader is unlocked, try flashing this recovery (modified TWRP).
If it doesn't work - unbrick guide.
Afterwards, use the OOS 3.0 installation guide from Bhalla
try this

What Have I done.... Soft Bricked A7G

Hello All
I have problem with my Axon7 G. I had 8.00 version installed and tried to make a system write option with using a method mentioned in
Official (Beta) Android 8.0.0 V1.30B01 EU Version by NFound thread. I flashed zip mentioned in this tread -ZTE_A7_UniversalBootStack.
Then restart devices and...whats happened....soft (or hard) bricked my phone!!!!!
1. After restart i had a standard warning about unlocked bootloader with yellow fonts . After 5 sec yellow fonts changed into red and wrote my device is corrupt...
2 using vol down i can enter into bootloader mode - then i can choose option like fastboot, recovery,restart and power off.
- pressing recovery and restrt , phone restart and again boot into bootloader mode with option above (cant get into twrp or stock recovery mode)
-pressing fastboot i can enter into this mode .
3 . Use fastboot mode to flash recovery and boot ( fastboot flash recovery recovery.img and fastboot flash boot boot.img)
everything seems ok but...nothing changed , i cant boot into recovery -twrp or stock. Still go back after restart to bootloader menu
4. edl mode.....i can`t enter . Use vol + and vol- and power button then after 3 sec phone went black screen with red light upper left. Applications cant recognize phone in this mode...
somene can help me ???
I also get the warning but I can just continue with the boot. I can't access recovery however. Don't know hot to fix that.
Ok I did this. A7 is working )
I flashed this via fastboot flash file: A2017G_B06_NOUGAT_STOCK_FASTBOOT_EDL.zip then i went into twrp and everything works

did you manage to get the error message away?
I got it recently after installing LOS 15.1, but for me everything works fine .
I'm just afraid if the device randomly reboots at night my alarm won't go off in the morning since it's the device is shutting itself down after the 30 second warning.
If you've fixed this can you please detail me through the steps.

Question Help with Nothing phone stuck in Fastboot mode (A13 Beta 1.5.1)

Hello,
I was trying to downgrade my phone from the beta to Android 12 and it's now stuck in Fastboot mode. Won't let me enter recovery. Tries to boot but just stays on the nothing logo. My bootloader is unlocked. I'm assuming I need the same firmware I was running to reload onto the phone. Any other files needed?
Thank you so much! cheers

I can't enter recovery mode. Only fastboot.
Flash boot and vendor_boot and you'll be right back in recovery
If it's not booting try set active slot to either a or B and flash the images mentioned above

I'm having a similar issue coming off a fastboot stuck device. I guess I managed to delete the recovery mode from slot B so I can't get into fastbootd to flash some of the lower level partitions to make my fingerprint sensor work.
The vendor_image is the recovery?
Did you guys find any solution? I am stuck with my phone stuck in the bootloader mode and I can't seem to do anything.
Here's what I did:
1) Unlocked bootloader while being on NOS 1.5.1 Beta. Successfuly did it.
2) Restarted my phone to bootloader mode and flashed dtbo, boot and vendor_boot from SuperiorOS 11th Feb build.
3) Proceeded to restart to recovery as mentioned in the instructions but instead of restarting to recovery, it restarted to bootloader.
4) Stuck in bootloader mode ever since!
Nothing seems to be working. I have tried literally everything but cannot get past the bootloader. Please help. I don't have any secondary device to use.
