[Google Pixel 7 Pro] simplepinoi177:
@EtherealRemnant isn't wrong. His link does go to the third post of THIS thread; which clearly is a "XDA thread" & "XDA post".

Even though EtherealRemnant didn't wish to clarify with you because English may not be your first language, I am willing...

"when the phone dropped" or "phone that dropped" is American English slang for when the phone (Pixel 7 Pro) first released (back in October 13).

He is correct again in pointing to that section of the thread/post because although the section isn't titled to re-lock the bootloader directly, the steps do include how to re-lock it as one of the "options" using the Official Google Android Flash Tool (option 1 if i recall correctly).

He is also correct in saying how you were incorrect at first when you didn't update your information for the Pixel 7; specifically that we need to patch the init_boot instead of the boot partition (it was apparent you were copying your guide from other devices [most likely Pixel 6] and it was incorrect for this device). It did take you a little while to correct that information. And also

for weeks

on updating via OTA "and maintain root" (which applies because it would fall under "wrong information on how to root") as you were insisting that using the Magisk "Install to Inactive Slot (after OTA)" was still applicable for our Pixel 7 devices...I know because I was pointing other users to that section of your post who were interested in attempting to do the "usual" applying OTA to inactive slot to retain root for weeks before you all of a sudden finally updated that it doesn't work and it's up to topjohnwu to update the method. I know you must remember that as it was a major shake-up on your guide that you modified as well as you must be aware how long it took you to update that information after initially creating this thread/guide -- as that method had never worked so it would be easy to measure how much time had past between the creation of this thread and when you modified that step.

It is getting kinda confusing that there are a number of rooting guides on here. I follow both of these in attempt to assist users on both and try and consolidate knowledge & experience from both when applicable in hopes to correct any of the "out of sync" info being passed around...

You should also consider adding supplemental info and implement steps to include using the Official Google Android Flash Tool as an option to re-lock the bootloader as that definitely and surely has more success and less-of-a-chance-of-bricking-the-device than attempting to manually run the fastboot commands (as the tool also flashes the factory image instead of merely resetting the phone) as well as it being from Google knows more what it's doing than many novice users -- it's hard to mess up when it's mostly automated and code is specifically written for the specific device and objective.

In my personal opinion, I figure applying a Full Factory Image with the "-w" command intact might be better than merely resetting the device; maybe something is kept (which is bad as for the same reason why the phone needs to be completely stock in order to be successful) by merely resetting it that bricks the phone when re-locking and/or going through the set-up process somehow does NOT keep it in "pure" stock form for the re-lock of the bootloader to be successful -- your steps state to "set up phone" at the end of "return phone to stock" (which you state to do in Step #1 in your Lock Bootloader section) when maybe that's a bad idea when re-locking the bootloader. Again, just my opinion and something you may want to consider...

But yeah...hopefully this helps YOU understand a bit of where the users that are getting confused by your guide are coming from as well as the users that are attempting to clarify things...
