bootloop after rom installation no TWRP no fastboot anymore - OnePlus 7 Pro Questions & Answers

hello
I have unlocked the Oneplus 7 Pro and installed twrp .
Have already had several roms installed and tried.
Wanted to try this morning the Rom Havoc-OS-v3.12-20201219-guacamole-Official-GApps.
Installed that and then twrp again.
Now I am in bootloop, I can not get into recovery. The TWRP logo appears briefly then reboot.
I can't get into the Fastboot either.
Is there still a solution ?
Thanks

Nexus 5 in Bootloop after unlocking and installing TWRP 2.8.7.1

Hello,
I wanted to install a custom Rom on my Nexus 5 running Android 6.0 so I downloaded TWRP latest and unlocked the Bootloader and installed TWRP.
Now the OS doesn't bootup anymore and the TWRP starts but gets rebooted all the time.
Tried to install an older TWRP version 2.8.70 and sideloaded and installed Pure Nexus Rom but this doesn't fix the problem.
Wiping anything from TWRP gives error messages...
Anyonw can help please!?
OK I have the stock recovery now installed from Android 6.0 and the OS boots up with Pure Nexus... looks OK,...
Anyway what's the problem with TWRP now!?
I don't think so. TWRP 2.8.7.1 is working fine for months. Did you full wipe before flashing your custom rom? Did you flash something else?
U need to install twrp 2.8.4.0 first because twrp 2.8.7.1 can only re-write on twrp 2.8.4.0 or higher..its work fine for me at official google M

That happened to me way back when I first used TWRP. From the official TWRP thread:
"If you have just used fastboot oem unlock, you should let the device boot up normally first before trying to install TWRP."
I think if you don't boot fully once before trying to install TWRP, it loops like that.

OnePlus one does not go into recovery after updating it

Hello everyone, I'll tell you what happened
First I was in CM13.1, then I flashed to oxygen OS 3.1.4 custom
(When I flash the ROM, without warning me the recovery was updated to the version TWRP 3.0.3-2TugaPower, previously being in a version inferior to 2.8)
After logging in to the new recovery, I noticed that the recovery version was not on the TWRP page, so I decided to flash the most recent version of TWRP (twrp-3.1.1-0-bacon.img), flashe it through Android sdk (Fastboot), everything went well the pc recognized me the OPO in fastboot Mode and flashe the recovery without problems, the problem came when I try to enter the new recovery the OPO does not enter the recovery stays in the OnePlus Logo.
(Before updating the recovery I tried to restate the backup of my previous rom CM13.1 but when I was going to restart it it stays in the OnePlus logo, and when I go to recovery I fixed that in the section of "Mount" system is not checked , Active but still the same, and when I return to recovery is removed.)
I ask you if you can give me ideas to be able to have recovery again and revive my OPO plz.

I guess you didn't read the OP of Oxygen Os correctly,he clearly mentioned that this 'Tuga Power Recovery' is patched to work with Oxygen Os's firmware and one should not flash any other recovery.Now,what you can do is this,
https://drive.google.com/file/d/0B-ikULjZZlloNHpOdVBrTzQxZzQ/view?usp=drive_web
> Download This file, install it somewhere and run Revert-2-CM.exe. Make sure you have fastboot drivers installed or it wont work.Avoid using any Antivirus program while doing this as they might give false alarms.After this you'll be restored to TWRP then you can flash any rom you want.The reason due to which you weren't able to find 'TugaPower Recovery' on TWRP page is because this is an Unofficial Recovery.
Question
What does the program do with the OPO?
If you are familiar with fastboot commands, this method should work. Had my OnePlus in the same situation last night messing around with Efidroid. Phone was bootlooping. Efidroid boot menu as well as recovery mode were both inaccessible. I had tried several other things but none worked for me. *CAUTION: this method did ERASE my userdata.* I downloaded a fastboot-able stock full firmware zip, then manually reflashed device. My beloved OnePlus is no longer my daily driver but still my fave device to experiment with so I just used COS 13.1 file. After full reboot, I downloaded and flashed official TWRP. Device is fully functional again, but without OOS installed.

It'll change your firmware and alter your recovery to a functional TWRP.You'll lose Oxygen Os after doing this.Though you can use this anytime when not being able to flash TWRP.
What should i do
Thanks a lot thanks to the method you told me my OPO has recovery again really thanks, but I have a question, I still in the TugaPower recovery, should I flash the stock recovery or the newest version of TWRP?
Because I do not know if flashing again the TWRP will happen the same

Messed my honor 6x. Help me recover.

Update: I tried flashing TWRP by Askuccio through fastboot and I successfully did. Then I flashed PixyOS v2.4 and flashed it successfully then flashed Gapps and stock recovery then followed rest of the required steps and everything went smooth and right. Using PixyOs now. Great rom with great stability with Android P. ?
I was on Oreo on my 6x. I wanted to flash this pixyos rom on my Honor 6x. I unlocked the bootloader of my phone installed the Twrp successfully without any hassle. Now it was time to flash PixyOs and unfortunately I did not do any backup of any sort. The PixyOs Package showed some error when I tried to clean flash it. And here we go my phone had No Os now. I searched a lot and found this thread
https://forum.xda-developers.com/honor-6x/how-to/update-bln-l22c675-emui-5-x-x-to-emui-8-t3819317
I gave it a try step by step thinking about that it would work but after successfully following all the mentioned steps and flashing everything I got this "System failed" error when the device was booting. In other words it didn't work eventually.
I tried the dload method with the same update zip from the thread linked above but it failed too.
I tried erecovery to restore my device but it gave me "Getting package info failed".
I don't know what to do now. Please help me with this and help me restore my phone.
I had the same issue
i made something like this a month ago
only one temporary solution worked is flashing EliteRom via twrp and i got the phone working again but still can't flash a stock rom.

Can you boot to fastboot. What did the PC say when you ran the script. Try to flash TWRP if EMUI 5 and then press and hold Volume Up and Power to boot into it. If it works, good. If not then again boot to bootloader and try to flash TWRP of EMUI 8. Again try to boot into it. If it works, good. Anyway, once you're in TWRP don't let your phone turn off. Plug it in charging. Now go-to wipe, and format data

I'd suggest you to try PixyOs (With Askuccio TWRP). It's a great and fluid ROM. Only downside is it doesn't have Stock Emui camera and I didn't even try flashing it because I read somewhere that it causes the device to get stuck in bootloop.

OP 6 freezes at fastboot screen after miui 10

I followed instructions carefully. Unlocked boot loader, installed Beta 11 (newest one), flashed TWRP. Next, flashed windows flasher.bat.......... back to fastboot, booted into recovery, VOILA, no TWRP, standard recovery. Reboot and stuck on bootloader. Have to unbrick and back to square one. happened 2 times. Now, there is an option in MIUI 10 unpack that has "flasher windows no format.bat. Anyone else having this problem?
Reading the instruction on the miui rom thread, i guess to understand that you need to boot twrp, it means you need to boot it like when you go to install it, miui rom has no twrp integrated, so in bootloader run twrp img via adb then install it as usual then flash the last miui 10 fix zip... Note that i give you this advice only by reading the thread because i've not tried that rom
I understand your apprehension, I would also, but thanks for your input.
The issue is when you flash miui 10 via instructions, it wipes out everything, so you have to re install twrp, but miui10 fixes zip is gone, and therefore it reboots to a frozen fastboot. OH well.........
Why you don't try to flash bluespark twrp recovery in fastboot? perhaps you need to reboot to recovery and flash magisk

You have to use OB8 in both slots or else MIUI 10 won't work.

OP6 Briked

Hello,
I've briked my phone trying to install TWRP with A10.
Now all I get is the boot menu with START, Recovery, etc.
Ive tried installing all the latest versions of TWRP and nothing.
Last thing I remember was attempting to install OOS 10.zip with a version of TWRP I got to work. Since that did not work I wiped and formatted.
Now nothing works. I just get the menu no mater what I Fastboot flash boot.
Any help welcomed.
Thanks!
Use MSM Tool to recover your phone.

Same thing happened to me I used the msm tool to unbrick it
Thanks, I ended up using the following:
https://forum.xda-developers.com/oneplus-6/how-to/how-to-flash-twrp-magisk-android-10-t3988213
https://forum.xda-developers.com/oneplus-6/how-to/rom-stock-fastboot-roms-oneplus-6-t3796665
Flashed 9.0.9 and then manually installed update for 10.
I was unable to get TWRP, Magisk with A10. With 9 it as simpler.
