You can, just move it to internal storage and flash or use OTG storage or even adb sideload.

Can't. Errorcode:: kDownloadManifestparseError.

Maybe a corrupt download of file. Try downloading again.

You are not being specific. How are you trying to flash the zip? Boot into TWRP, move the zip using a simple name like ota.zip in platform tools folder and go to twrp sideload.
In an admin command prompt from the same directory as the platform tools and ota, use this without quotes:
adb sideload ota.zip
make sure it's the right firmware.

I tried using TWRP flash and failed. Tried TWRP adb sideload and failed too. I think I have A12 firmware in slot A (I'm currently in slot B with lastest firmware 13.1) so I want to flash 13.0 F17 to slot A, but neither methods worked. Is it impossible to upgrade android version via TWRP?

In TWRP switch to slot A, try to sideload again, if it fails, switch back to slot B and reboot back to system. From what I am seeing you are on A13.1 and wanting to downgrade back to A13.0.....there could be an issue there in that procedure with downgrading!

 

[TheGhost1951]

Another possibility is to extract the zip file to get the payload.bin file and flash it with fastboot enhanced!

Unfortunately, you can't flash OOS OTAs with TWRP. At least not if you have a custom ROM installed. I never tried to do this with OOS already installed, but it might work. This is because all OOS full OTAs are marked as partial updates, which only updates a subset of partitions that have a time stamp older than the OTA. The problem is that custom ROMs, most of the time, don't have this time stamp set or are too recent.

You can either use MSM tool or extract the OOS OTA and flash partitions with fastboot.
Here is a project/script that uses the fastboot approach:

3. Option is universal:

1. Download boot.img
2. Reboot to bootloader
3. Run "fastboot boot boot.img" with the boot image
4. Go to Advanced > Flash Current TWRP
5. Reflash your custom kernel and Magisk.apk if previously installed

Sorry, I am a little bit confusted what to do exactly, because there are 3 files in the download.

There are 3 files in twrp-installer-3.7.0-12.1-8-lemonadep.zip
boot.img
ramdisk-recovery.img
twrp-installer-3.7.0-12.1-8-lemonadep.zip

I have a misflashed phone, which starts only in fastboot-mode, there is no recovery.

I have been told to install oneplus_9_pro_13.1.0.500ex01_firmware_flasher.zip too.

Please tell me which steps I have to do first.

The attached file, is the only screen where I can do something. Selecting recovery brings me back to this screen.

Use the MSM Tool to revert your phone back to initial factory settings. This will revert back to OOS11. Download the correct version of MSM Tool for your phone variant from this link. Turn off your phone and set it aside, DO NOT connect to PC yet. Once your download MSM Tool zip, extract it. Then run the exe file. Once it loads, click Start. It will now wait for device. Now come back to your phone, hold vol+ and vol- buttons (without power button) and connect the data cable. Your phone will enter EDL mode, but the screen will still be off. Your PC will recognize the device, and flashing will start. In about 4-5 mins, it will be done. Once your phone reboots, upgrade your phone through System Update OTA.

You only need boot.img and you can probably skip permant Installation (steps 4 and 5) in your case. If you cant boot you habe to flash vendor_boot and dtbo images of any known a12 vor a13 rom.
I don't know what oneplus_9_pro_13.1.0.500ex01_firmware_flasher.zip does and what your exact issue is so you have to rely on the recommendations you got

Thank you both. I have to say, that I want to install crdroid on the Lemonadep.

Use the MSM Tool to revert your phone back to initial factory settings.

I don't use Windows, but Linux-Ubuntu or Debian. I can organize a Win-Notebook if necessary. Is the Stock-ROM mandatory for going on?

So in which cases is ramdisk-recovery.img needed and when twrp-installer-3.7.0-12.1-8-lemonadep.zip

At the end I wand to have https://crdroid.net/apollon/9 installed, using the newest file from https://sourceforge.net/projects/crdroid/files/apollon/9.x/ Looks like newer files disappeared today, which yesterday existed.

For crdroid the following files exist: https://sourceforge.net/projects/crdroid/files/lemonadep/9.x/firmware/ I assume this is a fw-file? should be installed too with crdroid, but when.

As I undestand it, I should start with

fastboot boot boot.img

And then, there is the download link in the top of this thread, which is a zip file. Do I need to unpack this zip file?

Please tell me the steps exactly which I have to do.

If you just want to install crdroid it's best to follow the instructions from this thread:

[ROM][13][OOS Cam][OP9Pro] crDroid v9.8 [09.09.2023]

*** Disclaimer I am not responsible for any damage you made to your device You have been warned crDroid is designed to increase performance and reliability over stock Android for your device also attempting to bringing many of the best features...

forum.xda-developers.com

BTW your crdroid links are for another device and you should only download from this page:

crDroid.net - Download crDroid v9 for OnePlus 9 Pro (lemonadep)

official crDroid v9 for OnePlus 9 Pro (lemonadep)

crdroid.net

Running "fastboot boot boot.img" just loads TWRP into ram, without any modifications to your device. From there you can do all the TWRP things and also permanently install it. twrp-installer-3.7.0-12.1-8-lemonadep.zip is only needed if you want to install TWRP from any other recovery or from a userspace app (see installation options 1 and 2).

For more information about ramdisk-recovery.img read this post:

[RECOVERY][3.7.0_12-8][UNOFFICIAL][UNIFIED] TWRP with A12/A13 encryption support

This is an unofficial build of TWRP, based on the Android 12.1 branch, that supports encryption used by Android 12 and 13 ROMs. This build is tested on OP9 pro, but it was confirmed to work on regular OP9 too. As always I'm not responsible for...

Edit:
If you have problems with fastboot, you have to add your user to the "plugdev" group on debian systems. You can read more about this in section "How to use MTP, adb and fastbootD" of first post.

If you wannna flash crDroid, you don't need TWRP. Read the instructions on crDroid thread and you will see that you have to flash through adb sideload from the recovery image provided by crDroid. I must point out the fact that in OnePlus 9 (and all modern phones now) there is no dedicated recovery partition. Instead, recovery now resides inside boot.img. So thats why crDroid (and other ROM) instructions ask you to flash boot.img (along with dtbo.img and vendor_boot.img).

 

[lg-optimus]

If you just want to install crdroid it's best to follow the instructions from this thread:

There I started and now I am in this discussion. But maybe you see, what I did wrong:

fastboot --version
fastboot version 34.0.3-10161052

So the platform-tools were the newest about 1 week before.

fastboot oem unlock
OKAY [  0.035s]
Finished. Total time: 0.035s

then:

fastboot flash dtbo dtbo.img
Sending 'dtbo' (24576 KB)                          OKAY [  0.600s]
Writing 'dtbo'                                     OKAY [  0.054s]
Finished. Total time: 0.683s

fastboot flash vendor_boot vendor_boot.img
Sending 'vendor_boot' (196608 KB)                  OKAY [  4.753s]
Writing 'vendor_boot'                              OKAY [  0.467s]
Finished. Total time: 5.268s

I see no problems.

Then I downloaded from https://twrp.me/oneplus/oneplus9pro.html the file twrp-3.7.0_11-0-lemonadep.img and renamed it.

fastboot boot twrp.img
Sending 'boot.img' (196608 KB)                     OKAY [  4.644s]
Booting                                            OKAY [  0.443s]
Finished. Total time: 6.956s

Looks still good, doesn't it?

Note, I flashed the official version and not the xda-twrp. Maybe this was the problem.

Preferred Installation Method: Once booted, navigate to the Advanced > Flash Current TWRP option. This will install the TWRP image you just booted permanently to the device.

Errors, but it says twrp flash complete.

NOTE: You also need to use the “Fix Recovery Bootloop” option present in the same Advanced Tab. Use that option after you have installed the recovery ramdisk successfully to avoid boot loops happening from installing TWRP Permanently.

Then I didn't find the Option “Fix Recovery Bootloop”. Maybe TWRP from XDA is needed.

Then I shut down TWRP and started the phone again with the buttons and i ended, that there is only fastboot mode.

If you have problems with fastboot, you have to add your user to the "plugdev" group on debian systems

I never noticed problems. "fastboot devices" always worked. I have flashed more than 10 Xiaomi phones without problems, the newest is MI 10T Pro Apollo. Looks like the partitioning is different to OP 9Pro. The Apollo belongs to devices with a dedicated recovery partition (non-A/B), so there is no need to flash twrp into RAM first with Apollo.

From there you can do all the TWRP things and also permanently install it. twrp-installer-3.7.0-12.1-8-lemonadep.zip is only needed if you want to install TWRP from any other recovery or from a userspace app (see installation options 1 and 2).

Not sure, if I understand this correctly.

Can I do

fastboot boot boot.img

Then

fastboot reboot recovery

If that doesn't work, which buttons should I try?

Assuming, I started TWRP in RAM now, should I flash then:
twrp-installer-3.7.0-12.1-8-lemonadep.zip

You write it is only needed, when... But is it wrong to do it?

Do I have to restart recovery then?

Is the next step to install the custom rom?

BTW your crdroid links are for another device

There was something strange, when I wrote the post above, but didn't find out what was wrong. Locally I have crdroidandroid-13.0-20230612-lemonadep-v9.5.zip I hope this is a correct file.

. Read the instructions on crDroid thread and you will see that you have to flash through adb sideload from the recovery image provided by crDroid.

Thanks, but I have no adb-access anymore, there is only fastboot. See the screenshot above

It seems you don't read properly what we are telling you, do you? You DO NOT need TWRP to flash crDroid...... Follow crDroid thread, read the instructions properly, then you will understand.... Forget about TWRP if your only purpose is to flash a ROM....

 

[shadabkiani]

@der_akinator I see that in the latest folder 23-05-16, you have removed the OnePlus 9's unified recovery. Was there a problem? I remember it worked fine on my device, which is OP9. I still have it downloaded, but I just wanna know if there was an issue since you removed it.

Secondly, I would like to make a humble suggestion on the thread title. It currently says 3.7.0-12.1 but the recovery has been updated to 3.7.0_12-8. Also notice the _ and -. It would be better if written correctly, in my humble opinion.

P.S. I just downloaded boot.img from 23-05-16, and it worked too. Previously, it wouldn't work so you compiled and uploaded a separate version for OP9 for testing. So have you now fixed the main boot.img, and that's why you removed the test one?

Sorry for the confusion. After I got conformation that the boot images in lemonade-test work, I moved it to 23-05-16. That boot image now works for OOS 12 and 13 firmware and also on pro and non pro. There are no changes to twrp, just the kernel that is used to temporarily boot
