Nice to have a properly translated changelog, thanks. A mini-howto to do a manual update would also be nice :-)

What is the rule about firmware compatibility? I have a “international” version of the m2 note I guess, with current firmware version “4.5.1 I”. Can I (and should I) update using “A” or “U” versions available on the meizu website?


Yep ypu can use the A firmware (U and C are carrier specific, so nothing for us non-chinese).

To upgrade just download the file and open it in the Document app.

Thanks For The Update Bro,
What about the battery is it good now in holding charge
and why there is no FM radio in M2 note , can i install a FM Radio from Play store !!

Hi when I have installed 4.5.2A over 4.5.1I it has removed Google apps. I have tried installing Gapps installer from the App Centre but it wont Re-Install.

Also, is there a fix for sim 2 losing signal every minute or so, this didnt happen on 4.5.1I ?

I can also not find a version of 4.5.1I firmware to reinstall (Yes I know I should have backed up first).

Does anyone have a link to this firmware on the web ?

Many thanks


I recently bought the meizu m2 note.When i open it for first time has the Greek Language and works with it fine.When i install the 4.5.2A this language lost.You know what we can do ? Or what is the Custom firmware to downgrade it?
Many Thanks

Meizu customer services advised me this firmware is for the Chinese not international market.


This is correct, it is an A firmware, but basically there isn’t a huge difference between A and I firmwares.
The I firmware simply lacks the chinese applications and comes with Google Services included.
The A firmware then again has some chinese applications and lacks the Google Services (can be installed over Google Installer), but is in the core identical.

@AOKP is right ! I am using M2 Note chinese version (Firmware with A) and After selecting the English Language it works fine. it had some Chinese apps which I removed. Also I installed the Gapps using Gapp installer. Now every thing works fine.


Sir where I can download the International version of this firmware?

Thank you!

Hey guys please I need your help asap. I want to buy this phone but the seller says I can’t update it. If I update the firmware I will lose languages. Can someone tell me what languages will be lost after update? I only need English and I need updates to fix bugs. Thanks. Hope you can reply asap.

English is still included.

But your dealer was only half honest to you.
All devices which weren’t bought from an official partner, shop or Meizu Mart itself, won’t have warranty.
So be sure to ask for the original device invoice as well.

I bought meizu m2 note form china, i use use in europe. I use whatsupp in my phone. My friend’s whatsupp messages come late (15-20 minutes later). how can ı fix that problem.

Looks like your connection to Meizufans was lost, please wait while we try to reconnect.
