When I try to do this, all it tells me is waiting on device. I have the phone in recovery mode via fastboot and the phone says "now send the package you want to apply to the device with adb sideload <filename>". I have tried this over and over and it will not work. I have reinstalled the drivers a million times trying to get my PC to recognize the phone and that does not help either. Am I at the point of no return and my phone is done? I sure hope not because I have only had it for about 6 months. Any help would be greatly appreciated. Thanks!

something happened while I tried switching my ASUS_Z00A CN to WW and now its stuck in an endless boot loop, it will not get past the ASUS startup screen and I cannot get into the bootloader mode.

Any ideas on what to do next?
[ZenFone 2 Q&A, Help & Troubleshooting] Ex4_:
I have the same problem, any help is appreciated!
[ZenFone 2 Q&A, Help & Troubleshooting] Ex4_:
Okay I figured out how to solve the problem, if you f*ck up at flashing and you've bricked you're phone to death.

With Fastboot (on Windows PC) you need to erase the memory of the phone. Like, totally. Wipe all partitions and even the boot table, and rewrite them from a RAW firmware.

A tutorial on how to do so and save your phone you'll find here in post 8:

https://xdaforums.com/zenfone2/help/failed-remote-flashcmds-error-t3408414

Also if you're not even getting into Fastboot Mode anymore, use "xFSTK-Downloader" to get back into Fastboot Mode!

Need clarifications

Hi vivix,

First of all thank you for the effort and posting... I have few doubts.

I am having a cn version sku with ww firmware. When i try to update through phone NO updates available... but the one in OP is the latest so If I follow your steps...

1. will I be able to get regular OTA updates from ASUS?

2. Can I get the 100gb google drive offer?

3. After that If ROOT method available, will I be able to root it? (Note: not the pre rooted system files that are available)

4. Does my ZF2 retain the lte bands of CN?

Most important is to confirm or methods to find SKU ??? and firmware ( settings > about phone > software information> build number)

Your help would be of great.
[ZenFone 2 Q&A, Help & Troubleshooting] vincexda:
I'm not sure if I'll get OTA updates (or if they should be applied), but I've at least now got a proper WW phone that I can USE which I'm eternally grateful to Vivix for. In its CN state a lot of apps wouldn't even install, saying the app was 'not compatible with this version' but those very same apps now install perfectly, as do the standard Google apps which were missing from the CN phone, and even when installed via a google installer would periodically go mad and keep saying 'google play services has stopped unexpectedly'. I don't seem to have this issue anymore!

The firmware showing on my phone is LRX21V.WW-ASUS_Z00A-2.15.40.10_20150425_1396_user (followed by a lot of numbers, not sure if they're important??), I'm not sure about SKU, but everywhere on my device that WAS showing CN now says WW (I downloaded a device info app and the model now shows as WW-Z00A). Not sure about the LTE bands, mine works Ok with Three here in the UK, but with so many different bands in different countries, I can't say what the outcome would be.
[ZenFone 2 Q&A, Help & Troubleshooting] gopzzz:
Can you be a bit more informative...

1. Can you recall your previous firmware

2. are you able to activate 100gb google drive offer extended by ASUS

3. can you download the update file from ASUS official website and install it through recovery?

4. did you install the pre rooted system.img file?

thanks
[ZenFone 2 Q&A, Help & Troubleshooting] vincexda:
1.	I had downloaded CN_2.14.40.22 to my PC and copied that to the phone storage and installed it in the hope I would get Play Store etc (It didn’t!)....I tried a WW one after that, but that was when I realised you couldn't simply 'cross install' a WW firmware onto a CN phone...This was when I started my quest to work out how to flash WW onto a CN phone. This has taken several weeks, and I would have been looking at returning my phone were it not for Vivix, Chinaphonearena and Shakalaca, the brains behind this thread! I installed a ‘google installer’ from a Xiaomi support website, which did install play store etc, but they kept going beserk popping up ‘play services has unexpectedly stopped’ and ‘gapps has stopped’ every 2 seconds each time I updated and needed to reboot the phone to stop it!

2.	It looks like I HAVE got the 100GB of storage, as my current storage is 205GB. I pay a legacy plan of $20 per year for 80GB plus I got 25GB free from something else a while back. This has jumped up now to 205GB !! So it seems to have worked! Anyone know what happens when the 2 years runs out??

3.	The WW firmware I’m running is the one off of the Asus website. I downloaded it onto my phone SD card then copied it to the phone storage…nothing happened. I then downloaded it to my PC, and copied it to the phone storage and suddenly the update window popped up! Ran the install, it seemed to ‘halt’ the blue bar got stuck about 25% the way across for ages, then the phone suddenly restarted (other people have mentioned this happening, so maybe its ‘normal’ for Asus). At this point it said ‘upgrade successful’ and firmware IS the latest one! I didn’t need to rename the file from WW to CN as some people have. When a new WW firmware is available I’ll try and download that and install the same way.

4.	Yes, I installed the Pre-rooted image file….not sure if I needed to, or if it was a good idea (some people say OTA’s may no work or will boot loop going forward….though Vivix said in the thread this latest one should be fine for OTA’s in the future?)

Hope this helps, any other questions, let me know.
[ZenFone 2 Q&A, Help & Troubleshooting] vivix:
1. Im not sure if you will be able get OTA firmwares via WiFi updates on the phone. I didnt check that.

2. Yes, that offer is avaliable for ZF2 phone users since 2.15.40.10 firmware was released.

3.With my method you will install an original OTA firmware released by ASUS "STOCK" so when proper method wil be avaliable then : Yes

4. I dont know. There is different thread about it.
[ZenFone 2 Q&A, Help & Troubleshooting] gopzzz:
Thank you for the reply... I shall then try to update to the latest firmware..

Hi Vivix,

Can you update the OP with the latest and clear instructions to change CN to WW and also to update the firmware to the latest.

Moreover, sorg says it is not needed to flash fastboot.img file. can you make necessary changes if it is so... the link for his expert opinion here http://xdaforums.com/showpost.php?p=60654286&postcount=278

Thank you.... Waiting for the simplified clear separate instructions for changing and update...( please include stating STEP I, Step 2 etc.,)
[ZenFone 2 Q&A, Help & Troubleshooting] guiz11:
Since firmware change

Yes you will get the 100gb storage on drive, as I got mine plus 15gb from basic google drive so you will have 115gb storage.

I think in one or two week there will be an update, will try then to see if there's OTA update.

Concerning the LTE I didn't really test but seem like it didn't appear on my phone. In my country it's 18, 21. 3g seem so slow compare to my previous lg l7.

Battery so bad but this is general, sometime email, message app, etc close. need to uninstall an update and it will be ok.

Can't sync my contact from cloud, the asus app (people) so bad lol

The phone great in general, fast and responsive.

Hi guys, I bought a few days ago 550ML model with 2.15.40.13 stock ...

how can I do to make root without any problems? Then can I make ota updates?

Thanks in advance
[ZenFone 2 Q&A, Help & Troubleshooting] vincexda:
Hi Everyone,

Having converted my CN phone to WW over the weekend using 2.15.40.10, I noted on the Asus support website the new WW_2.15.40.13 is on there. I didn’t find anything OTA, but maybe its not rolled out yet. So I downloaded the file on my phone and moved it to the root of the internal storage, nothing happened, so I restarted my phone, and THEN the update message popped up (file still called ‘WW’ BTW, no renaming). It went through the update process (again the same strange blue bar stuck at 25% for ages then a sudden restart as has happened before). Phone then went through standard ‘Android is upgrading’ process, and now re-started on 2.15.40.13 firmware.

So we may or may not have lost OTA, it depends on when Asus actually release updates that way, but I’m happy to apply changes this way.

All the best.

Never get notification about new update

Hi Vivix,

many thanks to your post which helps me to upgrade software at my Zenfone 2. But I have a problem, maybe you can help me. I have two phones, both are totally same, both received at the same time from one supplier from China, both has version 2.13.40.13. One of them is OK, I followed your instructions and it upgraded to version 2.15.40.13 without problems. But big problem with second phone, because the notification about new OTA UPDATE never received. I tried clear cache in APP for FOTA and Google Services. I tried rename WW to CN., I tried copy ZIP file to memory card, I think I tried everything but NEVER pop-up a notification about new update. I spend more than 20 hours with google, etc, but no idea how to get notification after uploading .zip OTA file to root directory. As I wrote, one phone works fine, so I am sure that all steps I did correctly. Any idea? Your help is much appreciated.

I followed the steps, and everything it´s ok, so thanks vivix.

Now I have WW_2.15.40.10 version on my device.

I asked to one member of asus zentalk if from now on I will receive the OTA updates via internet,and he replied me:

"

yep, but if you are wrong version, when fota server sent file to your phone, you press update, it will detect your phone image, if wrong version, it will stop sent and mark on our fota server, you will not receive anymore"

I´ve noticed there is a new firmware version, .(WW_2.15.40.10),but cheking in my device new firmware update does not get nothing.

If this method does not work, Could we just put the UL-Z00A-WW-2.15.40.13-user.zip in the root mobile storage to update the OS?

or do we have to execute an adb sideload command?

thanks
[ZenFone 2 Q&A, Help & Troubleshooting] vivix:
Go to Mega Folder (1st post) and download recovery,boot and droidboot images of 15.40.13 . Flash them with guide and then you can update to full stock firmware via sideload, or phone update notification.

when you use sideload you need also intel drivers installed on your pc.
