[OnePlus 11] Rey Almanzor:
Hello, I am preparing this tutorial for the lucky ones who have bought a Oneplus 11 Chinese version, whether it is the PHB110 or another version, such as the Indian one, which, although latter allows you to choose between more languages, it is still the version for India. Complying with what I promised and responding to some colleagues on the forum, I will try to make it as simple as I can and I apologize for having to use the translator.

The steps are simple and it is a compendium of several XDA threads that I will detail later, but in no case, it is necessary to follow to the letter since each one is indicated for different options.

It is not necessary to root but you do need to open the bootloader for modifications. Both the process of unlocking the bootloader and the subsequent blocking eliminate the data we have on the device, so the first thing of all is to make a backup copy of all the data that we want to keep and, " very important! ", in case something goes wrong, we should also make a copy of the partitions, for it, there are many ways, although the one that seemed simplest to me was to install the twrp recovery and from the terminal use the backup commands in case it was necessary to recover the most important partitions .

1- Keeping this in my mind, we are going to start by copying the data to the PC. I did not save personal data because it is a new device, but whoever needs to save personal data can easily do it from Windows Explorer for photos, messages, etc. For full partitions, the best is to use the “CMD” command line after downloading the latest version of ADB and I advise extracting the files to a folder at the “C:” disk root drive to avoid having to type too much and make any unintentional error.

Whoever wants to use TWRP, just follow the steps detailed on this page and download the recovery https://droidwin.com/twrp-for-oneplus-11-is-available-but-should-you-install- it-now/

However, I already commented at the beggining that it is not necessary for the modification. It would be enough to activate the developer options just to open the directory where we have unzipped the ADB tools and type “CMD” in the navigation bar to open the command line in that folder. Once we have the command line open, the first thing to do is check that it detects our device with the command: "adb devices", this must return the device code number.

However, I assume that you already know how to back up your data, I am not going to spend more time on this topic so as not to make a huge tutorial.

2- From here I go directly into the matter, for this it is essential to pay attention to the Oneplus 11 device recovery tutorial that is perfectly explained in the thread https://xdaforums.com/t/op11-edl-downloadtool-to- restore-your-device-to-oxygenos-coloros.4607995/

To keep in mind since the thread started that things have changed a lot and to facilitate the process I recommend after the essential "mit and proxifier" files downloading and setting, which perfectly details the collegue "dekefake", that with no help from him, it would have been impossible to get througt the modification.

Finally, when everything´s ready, we´ll download a very important file for the process, https://github.com/libxzr/FastbootEnhance as well the ocdt file for the version that we are going to install, in this case it will be " CHP2449 " so, at this moment, you´ll be able to download it from the thread https://xdaforums.com/t/maybe-a-pro...erting-color-to-oxygen.4583321/#post-88504049

3- We start by flashing the payload.bin (I assume that you have already reviewed the threads that I´m pointing out and made a backup copy) to get throught this, we use the “Fastboot Enhance” tool, we run it and at the second tab, select the directory “superemmc” and flash "payload.bin" downloaded version 2449.

I emphasize that although some users affirm that it is necessary to repeat the process twice, in my experience, it hasn´t absoloutly not been necessary.

4- After successfully flashing the "payload.bin", you must flash the "ocdt cph2449.img" from the command line, to pull this off, we turn off the device and restart it in fastboot mode (volume + and home button), we check that fastboot also recognizes the device with the command "fastboot devices" and then "fastboot flash ocdt ocdt_CHP2449.img".

When we´re done, the device is ready to install the CHP2449 version with the EDL mode described at the first section.

5- Last step before finishing is to close the bootloader again. It is very important to use the original cable of our Oneplus due to many failures occur when using another cable! It was failing a lot when I was trying to block the bootloader. The correct command would be "fastboot flashing lock", so, as a result of this, now we have a new Oneplus 11 EU version.
