Z3 Dual [D6633] - Don't boot in to recovery

Hello guys, I don't have no more idea to fix it.
Today I unlocked my bootloader, all was Stock and no Root. I want try This Lineage OS 15 and is mandatory flash the TWRP to install the Rom.
OK, I unlocked my bootloader and downloaded TWRP Dual Version, extracted the img file from zip and flashed in fastboot mode like the tutorial says: fastboot flash FOTAKernel recovery.img
the flash was donne fine but I can't enter in recovery mode, I tryed in adb adb reboot recovery but isn't work too, anyone have an idea?
Attached some images to explain...
Sorry for my bad english.

Forget, xkeita give me a tip and I can now enter in recovery, I suppose that the Stock kernel don't boot it, just flashed the Kernel rom that I want to use and in sequence, flahsed the TWRP and it worked.
Sumary:
1. I extracted the Boot.img from ROM ZIP and flashed it with: fastboot flash boot boot.img
2. I Extracted the TWRP IMG and flashed it with: fastboot flash FOTAKernel recovery.img
reboot the phone, and turn on pressing vol key down ultil boot in TWRP.
Maybe this is usual to someone.
Thanks a lot @xkeita and @serajr for all the help and suport, I Learned a lot, thanks.
Moderators, can Lock this tread please....

Unable to flash TWRP. Lost Recovery, OS and only have unlocked bootloader.

Hi,
I was on Oxygen OS 10.0.0. Rooted with twrp-3.3.1-4-enchilada and magisk 20.1. (I had used this guide to do it. https://forum.xda-developers.com/oneplus-6/how-to/how-to-flash-twrp-magisk-android-10-t3988213) Today I downloaded the zip for 10.0.1 from the Oxygen Updater app and tried to flash it like I have done for OOS 9 in the past as usual. I went to recovery (I did not backup), I just wiped my data (not internal storage), cache and system. After that I tried to install the new zip but I got an error. It just said error unable to install. Didn't mention why. I tried flashing the older OOS 10 zip and got the same error.
So I thought I will try flashing on the other slot. I was on slot B. I switched to slot A and got the same error.
So I thought I will try to sideload. When I tried that I got the same error. So I thought I will try to reflash the twrp img itself. I went to fastboot mode and tried runnning this command
fastboot boot twrp-3.3.1-14-enchilada-Q-mauronofrio.img
It showed me this error
Sending 'boot.img' (65536 KB) OKAY [ 1.609s]
Booting FAILED (remote: 'unknown command')
fastboot: error: Command failed
Now I don't have any recovery at all. I have just the unlocked bootloader and no OS nor recovery. What can I do to flash TWRP again and install either OOS 10.0.1 zip or 10.0.0 zip? Any help will be great.
Thanks

So basically what happened there is TWRP doesn't boot with the oxygenos 10 bootloader. You will need to use the MSM download tool to unbrick your device.

But how is that? I was on stable OOS 10 before rooting following this link https://forum.xda-developers.com/oneplus-6/how-to/how-to-flash-twrp-magisk-android-10-t3988213. As per this, the first step is to flash twrp and that image did flash back when I did it. Any idea why it doesn't work now?
Also, do you have any links for the MSM download tool and any guide if there is?
Thanks

The problem isn't TWRP it's the bootloader. That's all I know. And for the MSM download tool. See attached link below.

Do not boot the twrp from fastboot it won't work
Just do
Fastboot flash boot twrp.img
Then reboot the device to twrp it will boot to trwp and then flash the new a10 zip and immediately afterwards flash the twrp zip

This doesn't work. It flashes successfully but when I select Reboot Recovery and press the power button, it boots back to the bootloader.

Maybe wrong twrp img
Try the older 3.3.1-12 twrp.img and then try
Also try the following as well
Fastboot flash boot_a twrp.img
Fastboot flash boot_b twrp.img
And try just reboot not reboot to recovery

Thanks so much for that! I have been able to recover the phone using MSM download tool. Now will update to 10 using the phones OTA.
However, I have one question, if I update to OOS 10.0.1, do you think this original post on rooting OOS 10, will work for it? https://forum.xda-developers.com/oneplus-6/how-to/how-to-flash-twrp-magisk-android-10-t3988213 Or do you suggest to not root and wait?

Put the TWRP zip and stock boot img on phone (a TWRP img is not a TWRP zip)
Remove Magisk modules first to avoid issues (in TWRP if you cannot boot to system. https://forum.xda-developers.com/showpost.php?p=72542167&postcount=242)
Update through local update to 10.3.2 is what I prefer to do. Then I do the following.
Reboot to let phone finish whatever. reboot into bootloader.
1. Fastboot TWRP img - fastboot flash boot twrp-3.3.1-18-enchilada-Q-mauronofrio.img - ( https://sourceforge.net/projects/ma...3.3.1-18-enchilada-Q-mauronofrio.img/download )
2. Use volume up to recovery and power button to boot to recovery
3. Flash 10.3.2 stock boot img while in TWRP (or current ROM stock boot img).
4. Flash TWRP zip while in TWRP (https://sourceforge.net/projects/ma...-enchilada-installer-mauronofrio.zip/download ) or Blu zip (https://github.com/engstk/android_device_oneplus_enchilada/releases)
5. Reboot to recovery
6. Flash Magisk 20.3 while in TWRP
(Flash a Q kernel if you want one other than stock)
7. Reboot system
You are now rooted

I had similar situation last evening.
I made the mistake of having a factory reset on rooted 9.0.8 and then trying to flash the 10.0.1
I got the same error, so I had to connect my mobile to my laptop, fastboot to the newest TWRP, flash the TWRP, flash the 9.0.9, flash the 10.0.1, flash magisk 20.x and then everything was working.

This worked for me.. Finally. PS - I did in a slightly different order. I installed twrp first, booted into twrp, made sure I was in slot A. If I wasnt, I rebooted to recovery. If I still wasnt I set slot to A manually then rebooted to recovery again. Flashed the stock boot img you linked to boot, then rebooted to recovery slot b (same process I did to get to slot a) then flashed the stock boot img to boot again THEN finally installed magisk. Booted to system, where it hanged a bit, rebooted before getting into android, but booted in just fine after that..
For some reason if you don't flash stock img to slot A (and maybe slot B too, I did this for good measure) before installing magisk everything dies a horrible death and breaks, which can't even be recovered from /boot /system backups..
EDIT: Tried to reboot into recovery, which reverted back to stock for some reason after doing the above steps. So I proceeded to install the bluspark recovery, rebooted into recovery, made sure I was in slot b, made a back up of the boot image, then flashed bluspark kernel. Got stuck at the unlocked bootloader screen. Rebooted into recovery, restored my /boot back. Still stuck when I try to boot into system. Fixed it by booting back into recovery in slot A flashing stock boot img, then into slot b stock boot, then magisk, but also installed bluspark kernel here because I had a feeling I would lose twrp from flashing to stock boot img, and that the issue was caused by twrp (both twrp-3.3.1-16-enchilada-installer-mauronofrio and twrp-3.3.1-x_blu_spark_v9.108_op6 have this issue). Guess what? Turns out I was right. Having twrp breaks everything after you install magisk, so you need to flash the stock boot img before flashing magisk for some reason.. and cant install twrp again unless you dont mind bricking your phone.
EDIT2: F2FS works, just boot into recovery via fastboot (this should be slot b), change /data to f2fs, boot back into fastboot then into recovery again by fastboot (slot b again), flash stock boot img > magisk > bluspark kernel > f2fs_fstab.zip > f2fs_optimize.zip > factory reset/wipe (from twrp before rebooting), done just reboot into system. You of course lose twrp because magisk doesnt like twrp on oos 10.x for some reason, and will need to set everything up again to cause of the wipe. If you dont factory reset/wipe from twrp before booting into system your system will crash and reboot every time you boot into android, then have to do all the steps I listed again.
EDIT3: Never mind, I was wrong, f2fs makes almost all your apps and storage unusable. Not sure if it's cause of the rom (OOS10.3.0) or because we have to flash stock boot.img and get rid of twrp before booting into system. Either way, f2fs has never really been stable or fun to get working so better to stick to ext4.. that few percent performance boost isnt worth it.
EDIT4: This is my last update. After experimenting with different things, bricking my phone, restoring it via fastboot rom, many many times, I've verified the simplest and cleanest way to install magisk.. Do note you wont be able to keep twrp.
Method A - If you already have twrp
Boot recovery into slot a, flash your rom's stock boot.img, then boot into your recovery in slot b (dont boot into slot a recovery because slot a wont have twrp anymore), flash your rom's stock boot.img, magisk and (optional) your kernel of choice (or not) in that order, then you can boot boot into system. That's it.
Method B - If you don't have twrp
Boot into fastboot, and from your cmd/terminal run fastboot flash boot yourtwrp.img (I suggest Mauronofrio's twrp-3.3.1-16-enchilada-Q-mauronofrio.img or newer). Use your volume buttons to select boot into recovery. Make sure your active slot is B, (if it isnt, install twrp (bluspark and Mauronofrio's twrp both work great) by zip, then follow the steps above in method A). Once you've verified you're in slot B flash your rom's stock boot.img, magisk and (optional) your kernel of choice (or not) in that order, then you can boot into system. That's it.
Maybe @mauronofrio or @eng.stk can verify why magisk or twrp bricks the system when you install them together on OOS 10.

@mauronofrio wrote the following in his TWRP thread a while ago:
So little update, after some tests i'm sure there is a compatibility problem between twrp and magisk, i was able to get only one of them, so actually i don't know how to proceed, i need to understand if it is a twrp problem or a magisk problem, TWRP is in stand-by for now.
There are not problems on Android Pie, if you need of the twrp on android Q just flash in boot partition the Q .img (fastboot flash boot twrp.img) and then reboot from fastboot in recovery. Before publishing the twrp I had not tested magisk and twrp together.
On Android 10 use only magisk 19.4

Basically worked for me, too, with 2 exceptions:
- this tool to remove magisk modules etc. wouldn't be flashed, always ended in an unnamed error; probably the cause for some other problems?
- flashing boot.img (V 10.3.4 from this thread) didn't work for me, I always ended up in twrp's splash screen
- got it solved by dirty flashing the full V 10.3.4 ROM (again from the above thread)
Many thanks once again!

I assume install .IMG to Ramdisk? It will likely come up, so just want to cover all bases.

I tried that...no dice...
Flash to both _a and _b using trwp but recovery does not boot... so back to trwp til some future info...

I flashed via TWRP, via flash .img to ramdisk, rebooted to recovery and nothing.
Stuck at "Bootloader unlocked" screen

Tried to boot via fastboot and it failed.

Was this recovery tested on the OP7 Pro? If so, what ROM was being used and what was the flashing process?

He updated it with fastboot flash, indicating that this is to be installed, however it doesn't appear to work at all at this point.

For me is working , latest OOS beta. Just had to disable vbmeta in order to boot.

we need a flashble zip for this.

is OTG working with OrangeFox ?

Not exactly, try - fastboot flash recovery *drag the image into the cmd then press enter*

Can this recovery be decreased in size so that it can be flashed to the ramdisk?
EDIT: It seems twrp is even bigger than this. Twrp img is 30.7mb while this is 29.4mb. Twrp does flash to the ramdisk. If this could be permanently flashed, it would be perfect. If the size needs to be decreased, certain graphics could be moved to the internal storage to save space on the ramdisk.

Hahaha wow what are you doing here it's like you didn't even test this at all. I'm tried to flash the installer in twrp and it tells me that this recovery is only for guacamole not OnePlus 7 pro. So it does not support custom roms clearly cause I'm on bliss

Dude what?
Fastboot Flash recovery recovery.img
That's it!
Hold Volume Up+ Power to boot the device to boot into Recovery.
Go to install and select customRomFileOfYourChoice.zip to install it.
Maybe needs a format Data to wipe failed encryption.
Reboot to system.

You need to install a custom ROM and format the data. If you are using an Android 12 or 13 ROM the data partition is encrypted that's why you're phone is boot looping

its working... I had to format data
thank you very much

All is working now. magisk installed (with trwp), lsposed install
But If i'm going in trwrp backup option, I don't see "system"

?

you have to mount the system partition first and set it via terminal to read/write i think.
But i am also not professional mhh..
Try mount it and when u cant Backup it ask again for help

When you rooted did you do fastboot flash or fastboot boot and then direct install in Magisk app?

I did the following:
Fastboot boot "patchedbootimage".img
Fastboot flash boot_a "patchedbootimage".img
Fastboot flash boot_b "patchedbootimage".img

Then you can't restore your original boot image from Magisk. You should only ever do fastboot boot and then use direct install in Magisk. Unfortunately the latest full rom available for your device is LE2115_11_F.17, so I think your only chance is that someone share a stock F18 boot image so that you can flash it and then update.

First command, you booted the patched boot image. All good. From there, install/open Magisk app and then select direct install option, and Magisk will automatically back up the stock boot and then flash the rooted boot.
Second commands shouldn't have been run.

So I was able to remove root by first following the same commands I used to root in the first place with the boot image you provided. However, I cannot update to F20 using the system update. It keeps failing

Ok, this time, you have to flash this unrooted boot.img that I provided. NOT just boot it like you do when trying to root. The system will check the flashed boot.img then proceed with OTA.
fastboot flash boot boot.img
Reboot, then try OTA update.
When you have the latest F.20 successfully booted, if you want root, you can get that boot.img through MSM readback feature. Or, I have F.20 boot.img too, and you can ask for that.

I followed your steps and it still gives an installation error. Just to make sure, I uninstalled magisk through the magist app as well. Further, I did some research on the MSM readback feature. Can you link me to the correct one to use?

The MSM Tool for Global thread is here, but the download link in first post is incomplete. You can download the full tool from here. Make sure to download the correct package. The global one also works for LE2110 (the Chinese model).
So you have flashed my boot.img, and then you are updating from where? Through system update OTA, or from zip file downloaded with Oxygen Updater app?

I tried both methods and both fail (through system update OTA, and from zip downloaded with oxygen updater app)
I did the following:
fastboot boot "stockboot"
fastboot flash boot "stockboot"
AND I TRIED THIS TOO:
fastboot boot "stockboot"
fastboot flash boot_a "stockboot"
fastboot flash boot_b "stockboot"

Why do you always "fastboot boot......" and then "fastboot flash boot...."?
Generally, fastboot boot.... will make you phone boot up the given image temporarily (whether it's a boot image or a bootable recovery image). Whereas, fastboot flash boot.... will permanently flash the given image. Normally, you only have to go with one of these methods depending on your task/goal.
Anyway, since you have flashed the stock unrooted boot.img and OTA is still failing, I suggest you just back up your personal data (photos, stuff) to PC or whatever, and then go with the MSM tool method. It will wipe all your data on phone, and revert your phone to OOS11 with locked bootloader. From there, you can take OTA updates all the way upto OOS13 F.20. This seems to be the simpler way to get out of your current predicament.

How to use MSM tool:
1. Download the package according to your device/variant, and extract it.
2. Power off your phone and keep it aside. DO NOT connect your phone to PC for now.
3. Run the MSM tool exe. It will take a couple of minutes to load.
4. Click on Target drop-down menu and choose O2 if you are on Global.
5. Click Start. It will go to Waiting for Device mode.
6. Now on your phone (which should already be powered off), press & hold both the vol+ and vol- buttons (NOT the power button) and connect the data cable from PC to your phone. Your phone's screen will still stay black and it will enter EDL mode.
7. The MSM tool will start flashing as soon as the connection is successful.
Note: You need to have OnePlus device drivers on PC.

I appreciate the support. Can you also provide me with the F20 boot image by any chance.

Sure. Stock unrooted F.20 boot.img attached. Make sure to unzip it.
By the way, if you have MSM tool, you can get your current boot.img from its readback feature. Super simple. Launch MSM tool. Press F8. Select the desired boot image (boot_a or boot_b). Enter the password as: oneplus. Click read. Power off phone, and get it into EDL mode by pressing holding vol- vol+ buttons then connecting data cable from PC. The desired boot.img will be dumped in C: drive.
Also, F.21 has just been released, so you better update to that. I haven't yet as I am currently on crDroid.
Anyway, F.20 boot has been attached.

Hello sir Can I get F.21 boot
vendor boot

there're no FULL package out there for Global variant
Just only incremental update
How can I get that Full Image?
Or Should I extract it from India Variant Full Image F.21
