[Motorola Edge 40 Pro  / Moto X40 (China)] mxz55:
By now it's pretty clear that Motorola OTA roll out is flawed, and not just as they keep saying in Lenovo support forum to be a staged roll out with different groups of users at one time. I think it's rather that their OTA backend is poorly designed and that there is lots of randomness.

I would advise the following to everyone that converts, or is looking for how to get OTA:

- Don't convert to/use RETEU, but go for RETUS. It's more cared for by Motorola, receives more updates (and quicker, including for security patch levels) and more stable, including for the ROM scene if you want to go with it in the future. RETUS will work globally with all carriers (also in Europe)

In perspective, RETEU T1TR33.43-20-28-2 (the one @y17ousef and @eemilv can't seem to get in OTA app) includes the July 2023 security update. T1TR33.43-20-28 (without the -2) is old asf and still on the April 2023 security update, as well that it ships numerous bugs like missing VPN capability, the known 'VPN dialog/settings entry not working'. To imagine that due to the roll out issues, many users are still stuck even with that major bug. RETEU (Edge 40 Pro variant) suffered a lack of priority and care from Motorola for long, not receiving any updates until Lenovo forum users finally got them to release the July update -2, while X40 (RETCN) and Edge+ 2023 (RETUS) are structurally treated with a better update policy. In contrast, RETUS T1TRS33.43-48-35 is August 2023 security update and of course there are numerous reasons why people are looking to convert Chinese X40 (RETCN) to global to begin with so we're not here to talk about the usability of its counterpart RETCN T1TR33.4-30-77 (also August 2023 security update)

So, it's clear how i back up that RETUS is better for everyone, on global devices. Now comes the practical part: those that were converting their device from china to global, by guides like this, were already unlocking bootloader and flashing the different variant firmware to do so. They just need to settle for RETUS versions. Anyone else that is simply frustrated with the bad OTA and hampered roll out (they can't seem to get it in OTA app) i recommend to unlock their bootloader and manually flash the latest RETUS. There is a possibility that due to its general better care with software policy, and being more stable than RETEU, that once you converted to RETUS (from RETEU or RETCN) you will face less problems to get the updates to show up in OTA app in a timely manner (even though experiences from users like this one at Lenovo forums is less than hopeful), but i would advise to just keep manually updating (flashing) anyways. It corroborates the randomness that comes with a poorly designed OTA backend that i mentioned i think is present in the beginning. So, if you are egilible and offered the update, it can even disappear indefinitely.

To get to the point

For anyone enticed to make the move to RETUS, the latest version T1TRS33.43-48-35 isn't available on lolinet yet, but after almost a week this link that was uncovered here is still working: https://moto-rsd-prod-secure.s3.us-east-1.amazonaws.com/RTWO_G_T1TR33.43-48-35_subsidy-DEFAULT_regulatory-DEFAULT_cid50_CFC.xml.zip?AWSAccessKeyId=AKIAS37TSJMJY5VTZC6O&Expires=1696240546&Signature=z+KiP39ALZkJlbMZM90rma94X3w= and may be permanent after all. If it's not, i will add a re-upload on Google Drive later.

I did my best, it's not easy to punch through all the ** caused by Motorola's poor updates program

Also, last thing ill mention is that instead of depending on the OTA app's randomness in offering the correct update or not, "Lenovo Rescue and Smart Assistant (RSA)", a Windows PC program, should be able to install the latest version forcibly in Rescue mode, but the downside is that in the process it factory resets the device, and only offers the latest update for your phone's variant, so if this makes you stick to RETEU you can't get August 2023 security update yet, and so on.

Edit: if you'd like to convert to RETUS by that program without using manual flash instructions (or ever lolinet), all you gotta do is let Lenovo Rescue and Smart Assistant download the latest ROM for your own variant (yes, the firmware you'd like to convert away from) and when it's done downloading, close the download progress window and go to the DL cache folder that defaults to be within C:/ProgramData/RSA, find the download cache for the ROM package, delete all contents from the folder that has "CFC.xml" at the end, and extract the contents (e.g from the OTA zip package, like from the captured link above) of your desired ROM variant into that folder, without renaming it to how it's really called. Now hit Rescue (it begins flashing) in the program, you've just tricked it into thinking it's flashing what was initially ordered, this way you're using Motorola internal flashing tools to switch to ROM & fw you desire, without its RETCN, RETEU, RETUS detection deciding what it flashes. The simple truth is that it flashes whatever is in the download cache folder, without integrity checks, and i hope this won't ever be changed.
