Hi all,

There have many many discussions and comments here on the community about the status of this update. We've also received tweets and Facebook messages - so we know as ever, this is a highly anticipated update that all of you are waiting anxiously to receive. And we can see why - Cortana herself is worthy of an update like this.

We understand waiting for these updates can be frustrating, but with so many Lumia devices out there, it's understandably going to take Microsoft some time to ensure these updates offer a smooth and enjoyable experience for all customers.

15th Jan 2015 Update
Today, we have approved the latest Denim update for the following Lumia models:
520, 620, 625, 720 and 1320

These updates now sit with Microsoft to schedule and launch to customers. Just to ensure you're 100% in the picture here - the testing and approval process for the above devices is now complete on our end. We are in talks with Microsoft to get a more accurate ETA for release and we do still expect this to be this month, but as and when we receive any confirmations or updates i'll be sure to keep everyone updated here.

What about the others?
We understand the frustration if you have a handset other than the 5 mentioned above, but we assure you we'll work as best we can to test and approve other Denim updates as and when they reach us - that is to confirm that we have not yet received updates for any other Lumia (other than those above) to test. Again, i'll keep you updated as and when we receive other updates for testing.

19th Jan 2015 Update
What models are getting the 'full treatment' and which are just OS updates?
For the updates we have approved and sent back to Microsoft so far - that's the 520, 620, 625, 720 and 1320 - these are the newest updates to the Windows Phone operating system. They do not contain the full range of firmware updates such as the camera improvements that Denim is known for.

What updates are you waiting to receive for testing?
Okay... Deep breath! 530, 630, 635, 735, 820, 830, 920, 925, 930, 1020 & 1520

Will those be the full Denim updates?
Mostly yes, with the exception of the 820 & 920 which will receive a similar OS update to the aforementioned models.

When will you get them and when will we get to download it?
We don't currently have any ETA for receiving these from Microsoft but we'll be sure to keep you updated as and when that changes. Once we have approved the updates, we'll send them back to Microsoft to schedule it for release to customers - this typically takes 1-2 weeks after we approve.

Last words
I know waiting for these updates can be frustrating. I'd like to emphasise that we're sorting the testing out as soon as we get updates and sending them back for release - we're absolutely on the ball with these updates and will do everything we can to limit the time it will take for you to receive this, but some of the process is outside our control (eg, the update being scheduled for release to customers) and we'll do all we can to keep you in the loop.

3rd Feb Update
Denim for the 635 and 1520 are out now. Please see below for info relating to the 930 update

We’re trying to get the updates out sooner by streamlining the test and approval process. As a result, we are trusting Microsoft to test the O2 software updates for us and provide the results of the tests for us to approve, rather than us testing it, releasing back, and waiting for it to be pushed. In the case of the Lumia 930, the Cortana issue was missed by Microsoft, so we will be working together to improve the process for future updates.

Microsoft have identified the issue and have fixed it - as a result, the previous 930 update has been put on hold until it's replaced with the fixed update which we hope will go out soon, though no ETA has been provided.

6th Feb Update
Hi all, just a quick update with regards to the fixed 930 update. We've been given the heads up from Microsoft that this is scheduled to start pushing out from 6pm tonight (Friday 6th Feb). If you don't see the update immediately then don't worry - in case their servers are a bit busy, we'd suggest trying again a few hours later should you encounter any issues.


11th Feb Update

Hi everyone, just another update to let you know that the Denim update for the Lumia 925 and 1020 will be going live tonight! I know owners of these devices will be keen to update quickly so please do let us know how you get on.
Other Lumia owners... I know the wait is excruciating but hopefully not long before yours is made live too.

7th March Update

Hi everyone, just wanted to let you know that the Denim update for the Lumia 530 and 735 are now available OTA, and this should conclude all O2 devices now having Denim available to them. I know it's been a frustrating wait for many but we've done all we could to streamline the process and we're pleased the updates are now all readily available.

Hi. I'm from the Social Media Team.

Come on O2. You've made your Christmas money from forcing people to upgrade their phone if they wanted Cortana straight away, the rest of us are sticking to our 'old' phones (mine is only 2 months old!), so please, for the love of Jobs, free our update to our phones.


Thank you.

I hard reset my 925 a few days ago and after putting it back into service yesterday I notice it's now running Denim.


In Extras & Info I noticed on the 925:

Mobile Operator = 020-GB

I've an 830 also which = 000-GB


Am I right in saying the 020-GB means it gets updates from O2 in the UK? (After they've received them from Nokia/Msoft and checked them)

And the 000-GB means it gets updates direct from Microsoft/Nokia when they send them out to UK?

Yes, those assumptions are correct.
I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.

Currently using:
OnePlus 6 (O2 & Sfr), Z3 Tablet (Three UK), iPhone 8+ (EE)

@Chris_K  from social media posted this on the 19th December. As soon as there is further news he will be back to update us

"We have not received any updates for testing yet - At present we still expect to work closely with Microsoft to get a Q1 release for many Lumia devices, still possibly as early as January. With the information we have, this should be similar for all UK networks - we're not aware of it being available officially on any UK network at present."

*The Game Is On*

Something is amiss, o2 know customers are waiting for the denim update plus cortana, relying on information, I have received from a reliable source, the update will roll out between Feb 2015 - April 2015 after testing, its just that o2 wont admit it.

Whose misleading us O2 or MS?

Doesn't help me, I just have the 1520 - but an official answer from O2 would be nice, polite even...

Thats strange, my 620 is what I believe is called a Country Variant model 000-GB but is still on Cyan, just checked for updates and none available. I'm not bothered though as it's a spare now and Cortana isn't for me.
