switch from cn to ww firmware - ZenFone 2 Q&A, Help & Troubleshooting

hey,
in the past i tried to change my zenfone 2 rom, so i rooted it and i also had to update its firmware,
i tried to update it through asos website but i guess i made a mistake somewhere along the way and now i have what appears to be the Chinese firmware version. and alost the phone isn't rooted anymore.
i can't get online if i dont have wifi and i dont have google apps. very frustrating.
i want to try to change the firmware back to ww (worldwide?).
will this solve my internet and google apps problem?
how do i do this?
my current firmware version is: LRX21V.CN-Asus_Z00A-2.20.40.185_20160504_5537_user.....

Latest software version for SM-N910A

My gear VR dosn't work and I'm trying to find latest software version for N910A, because update doesn't work in Europe I have to do it manually.
I could only find stock default soft on this forum
OR what's the name of the latest baseband? My current is default N910AUCU1ANIE so I can google it
I tried using IPVanish to pretend I'm in america but rubbish AT&T updater tells me to wait 24 hours again. (flashing through odin helps to skip that)
I don't know what your trying to do but I know you can change the date on your phone by a day forward after unchecking auto date and time in the settings. Worked for me when I heard at&t had a update out and I already had checked for a ota that day.

You can't do anything unless you have at&t sim card in your phone and you are on at&t network. Otherwise phone will not update, also do to lock bootloader and no root we can't pull update from phone to create current firmware. Your phone is on last avalable official firmware and longest you can't get phone on at&t network or someone find root for this phone you can't update. Sorry for bad news.
Edit: If you in London have Samsung store you can go there and see if they can update your phone true Smart Tool.
Clicking from notecable N910A
Thread cleaned. Keep it on topic folks.
If this was posted elsewhere in addition to here, try reporting it and you may find it gets addressed. Thank you.
My current is default N910AUCU1ANIE too . Can't update

CN version but firmware came with WW, should update to WW or CN?

The box says CN, but phone came in sealed box with WW_2.13.40.13.
I see WW update on 27-APR and CN update 20-APR. Is it safe to use latest WW update? I only ask because current version says WW.
Why not just release WW version to all areas and save everyone a big headache. Besides the point. What's your advice?
I saw a post where someone stated they ordered the TW version and were able to do an OTA update to the WW firmware.
The OTA is not offering me any update when checking. Doesn't say anything when I check. Checks for a minute, then just returns to the main update screen.
According to build it says build LRX21V.WW-ASUS_Z00A-2.13.40.13_20150401_8390_user.........
So strange they caution against using CN version with WW version and vice versa, but they gave me a CN phone with WW flashed. :| WTF? Just don't want to F the phone up.

My box said TW but phone came with WW firmware. I updated as recommended and have the new WW firmware and 100gb of free Google Drive storage.
You updated via OTA Twotems?
Installation aborted. Getting error:
Device image SKU: CN
OTA image SKU: WW
So this makes some sense, other than that current firmware says "WW".
There is newer CN ROM available according to Asus site, but OTA not offering it up. Suppose next step is to just use the latest CN software from the site.

This difference is because of Recovery is of CN and Rom of WW. Boot into Recovery, I am sure it will be CN.
You need to flash Recovery image of WW.

Now that I've updated to latest CN version (because couldn't update to WW version), I have no Play and can't go back to WW because of the build.prop Sku is CN error. :|
Here is more about he current problem. http://forum.xda-developers.com/zenfone2/general/alternative-flash-method-t3095834
Sorry, maybe a mod can combine these two threads.
The error says specifically it's a build.prop issue, you think flashing WW recovery will fix that, and where to get it and how to flash it only?
I purchased two Chinese versions and converted them to WW. So easy and no issues
Are you able to get 3G in your home country? The Asus site isn't clear, it says 850/900/1900/2100 and 1900-2100 TD-SCDMA (China/India). Not sure if that means CN/IN version has only TD-SCDMA, or it has TD-SCDMA in addition to 850/900/1900/2100. What baseband are you on?
EDIT, NM: I've confirmed 3G/H+ working on 2100.

I'd also appreciate a link to how this is done, as I'm stuck on a CN ROM, but would prefer a WW version, a couple of links I've found point towards flashing boot images, but the links were dead.
Many thanks

I found this thread, and followed the instructions, and now my CN phone is running the WW firmware with all the google apps that were missing from the phone when I got it!
http://forum.xda-developers.com/zenfone2/help/how-to-upgrade-cn-version-to-ww-t3101556
The biggest problem was getting my phone to be seen under fastboot commands, but I eventually seemed to fix tha by navigating to the folder where fastboot.exe was, and putting all the relevant files in there as well, then it seemed to work OK.
Finaly i use this solution and now my phone is on WW firmware.
Tnx!

[Q] How to change CN rom to WW rom....

Hi, i will get mine in 2 days and i was wondering how can i change the rom so i can have playstore etc. I read somewhere that all i need is to download the WW rom and put it in the phone root. Is this correct? Thanks.

Ordered Asus Zenfone 2 and Received a rooted Device. Shall i Un-root?

Guys i recently ordered an Asus Zenfone 2 Deluxe from a Chinese retailer. Obviously because the phone was the Chinese or Taiwanese Version they rooted the device and installed a WW Firmware before shipping it to me. The Version i have is 2.19.40.18 but the battary life is really bad. I realised all this when i tried to search for firmware updates but there is no way to search from the settings menu and the OTA Solution doesn't seem to work because i don't get a notification to update.
ADB doesn't work either because the 3 PCS i installed all the necessary drivers on, i couldn't get them to correctly recognise the device.
Anyways, i just want to be able to update the device to the latest WW software version, i don't care about the root if i will loose it because i don't use the device as a superuser.
What do you advice?
Same situation here. I have the same software version (both on device and in recovery). I also want to update the sofware but OTA option is unavailable in the SOFTWARE INFORMATION MENU, I tried manually but it doesnt work. I dont even know the root method used by seller so I dont know how to unroot, neither will unroot make manual OTA possible.
Please help someone.

12.5 update on QGGMIXM

So, this may be a dumb question but I can't seem to find the answer anywhere. I have my phone for almost two years now, and it used to get the updates the right way, until the 12.0.7, then it just stopped getting any updates, when I checked it says "no updates avaliable".
Searching yesterday, I manage to update it to 12.0.8 by changing the device region to India, but it just stopped there, I can't update to 12.5 or further.
While searching i've seen that the devices different from QGGMIXM (which mine is), like RGGMIXM already got the updates.
I even tried to install the 12.5 update (for RGGMIXM) manually and it said it could not verify the update.
Is there any way to change QGGMIXM to RGGMIXM or to get the update without changing it? Any help are appreciated

1/ Just tried vpn, didn't work
2/ Neither downgrading or upgrading worked, downgrading says it's unable to downgrade and tried to upgrade says it couldn't verify the update
3/ I haven't tried this yet, but I'm guessing it'll be the only way to update it.
