Error applying update: 29 (OnePlus Nord - avicii

Using /e/OS Troubleshooting

(This is the continuation of treat After flashing TWRP only bootloader accessible - #11 by JamesM)
I have reinstalled the Oxygen OS and updated it to the latest version “nord oxygenos 11.1.10.10.AC01BA”. I followed the instructions “Install /e/OS on a OnePlus Nord - ‘avicii’” step by step. But flashing (sideload from adb) of “e-2.4.1-s-20241009439849-official-avicii” stopped after the verification request with this message:

 Installing update...
 Step 1/2
 Error applying update: 29 (ErrorCode::kDownloadOperationHashMismatch)
 E:Error in /sideload/package.zip

I have gone through the process several times with always the same result.
The checksum from the rom is correct and the platform tools are also the latest ones.

The recovery “e-2.4.1-s-20241009439849-official-avicii” is installed on both slots (a and b) and is also running. But none of the roms.

I have jumped straight to the end of this thread but I think the posts before contain some explanations Oneplus Nord manual installation problems - #69 by langedarm

This tread helped me a lot with the first problem. But I couldn´t finde anything about the “Error applying update: 29”

I do not know the significance of error 29.

Until Android 13 (T) many users had difficulty with the exact oxygen version with which to prepare the device. At one point Post # 59 I mention the possibility of contamination caused by the wrong bits of “mixed” Android version (or firmware revisions) existing on the device. I am guessing that the “mismatch in the zip” reported in the error is loosely speaking due to this sort of problem.

The big selling point for T is that one gets to flash a whole matching build – that is to say that one is far less dependent on the pre-existing stock ROM as long as it is fully updated — as I demonstrated explaining about vendor parts Post # 65.

With a correction of a typo:

That´s it !
I flashed the T and everything is fine !

Thank´s alot for your support !!

Are you getting VoLTE and have 5G working?

VoLTE is working.
My mobile phone contract doesn´include 5G. So I can´t test them.
