ZENFONE 5 ZE620KL [OFFICIAL] Android 9 - Pie

UPDATED: Official Android Pie (9) is now available for the WW variant.
Do you want the update? Read on!
You can download from here (~1,88 GB): https://dlcdnets.asus.com/pub/ASUS/ZenFone/ZE620KL/UL-ASUS_X00QD-ASUS-16.0610.1812.58-1.1.15-user.zip
You must be on WW 15.0619.1810.73 or Android Pie Beta in order to update! If you're on a different ROM, you may brick your phone!
Update method A:
Download the file - linked above
Put it on your phone to "Internal Storage" (root of Internal Storage, don't put it into folders like Download/DCIM/Android, whatver...)
Restart phone (Power button > Restart)
After restart, you'll get a notification, that a new software is available. Yes, install it. Wait until it's complete and you're done!
Update method B:
Download the file - linked above
Put it on your phone's SD card (this only works if you have an sd card in your phone - obviously)
Turn off phone
Hold down Volume Up and Power buttons for a couple of seconds (until the ASUS logo appears)
Choose "Apply update from SD card", choose the zip file and do the update
Reboot after done (or wipe data/cache if you want)
...or you can also use ADB to sideload the file, but I won't detail it now (unless requested).
About Pie notes
Camer is same as before.
Digital Wellbeing app isn't compatible with the device.
New gesture based navigation is working, new dark theme is available in ASUS theme app, new animations are also working.

Thank you for this information. The first method worked well with me.

Careful with that one. It says "TW SKU only", so it might not work/have issues with WW versions or CN versions.

Were you on WW 15.0619.1810.73? Because if you were on a version ending "1810.67", then the update fails.
What is the error message?

That's the stable version released today for the Taiwanese SKU

There was a new release from Asus official website featuring the Android Pie (WW_16_0610_1812_58) like three days ago. It was featured in Asus PH and Taiwan, although I checked that two only. Although, it is unavailable since yesterday until now.

Is it safe to update this?
Ive already updated android pie with this "WW_ZE620KL-15.0619.1810.73-16.0610.1812.52-12051038-fota-user.zip" but it has many bugs. Can I update it again using this new update? Is it safe? Pls reply. If it is ok. Thanks

The update can't be found on Asus official website any longer, this would mean something, wouldn't it? In any case, it wasn't WW version, so it isn't good for European Zenfones. Am I wrong?

I just got confused because at that time I was accessing several different Asus Website (Taiwan, India, Brazil, USA, Philippines).
Although, I was able to implement the update from
version _52 to version _58. And my SKU is WW.
But I really think I got it from Asus Philippines' official website. ?
Currently, on the Asus Taiwan official website is the only one with the software update is available when I last checked.

Question Rollback Process

Sorry for this noob question
But there any way to Rollback to C.09 Update or Rollback to Android 10

There's a link to an Android 10 rollback package in the Android 11 announcement in the Indian community forums. That seems the easiest approach and according to smiley.raver in another thread you don't need to match Android 10 firmware with your region.
Alternatively you could flash some Android 10 firmware directly. You can find some links to downloads from realme on various sites such as realmefirmware that could you could flash with your favourite MTK flash tool. My choice would be mtkclient because I prefer to use Linux where possible but quite likely the choices for Windoze would be more user friendly.
Good luck! (I am a Noob too.)

Thanks for Reply Bro...
The post from Realme community where Rollback package is given..
Some users said...that's package not working its failed white downgrading
And I m also gonna use Linux after few days...What's is step of MTK client on Linux

And Also I downloaded file from Realmefirmware site ...
But don't find exact process for flash it

Is that right? I skimmed across the thread and didn't notice remarks like that. Anyway, I can't help you either way as I haven't tried myself.

No idea. Did I mention I was a Noob? You probably will find a guide to MTK flashing in one or more threads on this site.

Again Thanks for Reply
I will try myself

Backup all the partitions of your phone first and let us all know of your success.

it depends on the firmware file format
it also depends on if you have full firmware file vs upgraded file

Hi, I'm trying to download back to Android 10 to perform the region hack to enable the Dual Sim functionality from Australian Optus prepaid Realme C21.
But I'm stuck. I downloaded this file from the realme forums, talking about a rollback package.
RMX3061PU_11_OTA_0370_all_kpNiOQ0SFsQk.ozip
But as i follow the instructions it tells me, the install version is older hence wont continue. This is with the built in recovery method.
Mainly posts mention that the special rollback ozip can be used to downgrade but for some reason the recovery wont allow me.
I'm not clear as to how I can downgrade back to Android 10.
I know there are roms (how do I flash these??? do I need to unlock bootloader), then were are ozips which are realme stock roms.
So what is the best way to downgrade back to 10??
Just want to get back to 10 so I can change the region to the 'optus prepaid xxxx', to get dual sim.

yes please.
Could you share how you downgraded?
I've been looking at flashing it directly with the zip firmwares you can download. But the process seems complex and I haven't found a clear way to do it.
Just want to downgrade to android 10, change region then enable dual sim and then allow it to upgrade back to 11 and 12 I guess.

If you use telegram
Msg me on

This ID
I cna explain there and can send You necessary files ..

I have a theory.
Use mtk-client to unlock bootloader.
Install twrp with all in one tool. (not sure if need to use auth bypass hacks).
use twrp to flash android 10 ozip.
then try to boot into android 10.
use region change codes to perform change.
possibly restore recovery to stock, then lock bootloader and use OTA or ozip upgrades to upgrade to latest.

Question How to convert LE2111 OP9 phone to EU ROM?

[Posting here since this forum seem a bit more active than OP9 forum.]
Hi guy. What are the steps I can follow to convert my Indian(LE2111) OP9 with Indian Oxygen OS to EU variant?
Wanted to get away from the bloatware in Indian ROM & EU variant seems to support dual SIM. Also want the US version of Gpay, etc.
I downloaded Oxygen Updater , changed device to OP9(EU) & downloaded the full OTA ROM. When I try to "Local Install " on Settings page it says "verification failed".
I also downloaded the LocalUpdater apk, which also fails.
I haven't unlocked the bootloader or rooted the device
What steps am I missing?

I have the same needs but for my OnePlus 9 Pro.
Try to follow steps I did: https://forum.xda-developers.com/t/...-chinese-variant-le2120.4269767/post-87447209

Thanks for responding. It's seeming like the process has changed a lot since the last time I flashed ROMs back in OnePlus One days. lol
I'm currently on LE2111(Indian ROM) C60 on Indian variant OP9(dual sim, no wireless charging). I want to move over to EU ROM.
So are the steps:
1. Downgrade to android 11 using MSM Indian tool.
2. Flash android 11 using MSM EU tool
3. Update from OTA/Oxygen Updater.
??

Or you could do it in simpler way: after downgrading to A11 with MSM Indian tool use Oxygen Updater and select EU device, in the app’s settings: “Stable (full)” update method and enable advanced mode.
This will let you download the latest EU full ZIP, which you can install via the system’s built-in “local install” feature or the separate local upgrade APK https://oxygenos.oneplus.net/OPLocalUpdate_For_Android12.apk

Tried it. Got to A11 using Indian MSM. The local upgrade option still fails with the EU full zip saying "System update installation failed"

Then go with your bullets 1. - 3.

I have proposed a modification based on the input I've got from someone else but apparently it doesn't work.

Question Error trying to update via OTA

A few weeks ago I bought the Oneplus 11, now that the latest version Global A.07 has come out, I get the following error, I have tried with Oxygen Updater and I still get an error when updating, I have automatic updates enabled from the developer options.
The model is CPH2451

If you're still on A.06 and trying to update to A.07 (and you're rooted on A.06), then you need to flash the stock A.06 init_boot.img before updating. Not 100% sure, but believe that someone posted the stock A.06 init_boot.img for the US version in one of the other threads on here, if not maybe you can ask in those threads if anyone has the unpatched A.06 init_boot.img as only way to do incremental update is if your system is stock. It's the bad part about the US only getting incremental updates instead of the full packages like every other region does.

View the thread here. It has the stock A.06 and A.07 init_boot.img. You can flash which ever one you're currently on then update. I would also recommend following that guide to root the US version of the 11 in the future.

No problem, also wouldn't personally recommend converting. You risk bricking for little to no advantage and if you do brick there's no free way to recover (as MSM is no longer free and open). I would just stay on 2451 and use that guide for updates.
