The rom is awesome, but presents some problems, certainly not the fault of the developer:

- The phone is significantly faster, but it also heats up more

- Some few apps malfunction (Android 7 + Intel fault?)

- The battery lasts less

- Usual Intel problem + video decoder / encoder custom rom (fullscreen chrome videos that freeze the phone, videos made by whatsapp with green lines, some video formats impossible to play, etc ...

- and other minor problems

I love this rom and the great support work that the developer does, but for me the best user experience on Zenfone 2 it is obtained with the original 6.0.1 rom.

When Android 6 becomes unusable it will be time to switch phones :)
[ZenFone 2 Android Development] E.U.G.O.R:
thanks , but i want the higher android version, its why I ask which is the most stable 7.1 rom

Any updates for Apr/May security patch?
[ZenFone 2 Android Development] bernardobas:
No, maybe next month if I have time.
[ZenFone 2 Android Development] str4610:
I use this ROM for #Z00T

My experiences:

Root with magisk

Good speed and fluency

Very good battery usage

Use #LSpeed to run Call of Duty mobile smoothly

I am completely satisfied. Thank
[ZenFone 2 Android Development] stingbandel:
this roms is really good and stable even though it's still nougat. I can run whatever I throw to this phone... however, would it be possible to update the security patch on this @bernardobas ? thanks

Dear developer, it has been a long time since you thought about the update

[ZenFone 2 Android Development] solar10:
Dear Dev/Maintainer, thank you for this ROM. Works like a charm on my venerable Z00A.

Since Android 7 is getting closer to EOL, what are your plans for future releases ?
[ZenFone 2 Android Development] dingdong3000:
I'll be happy if maintainer just keep up the security updates from time to time. As always great job, thanks!

How long does it take to give a security update without taking action?
[ZenFone 2 Android Development] bernardobas:
My device is dead so I won't be making new releases.

Maybe someone else can keep things rolling, sources are on Github.

Good luck to everyone.
[ZenFone 2 Android Development] hellokelly:
dead as in motherboard died and needs to be replaced no repairshop has them in stock anymore and it needs to be ordered from china ( which is with import taxes / customs wait time etc.. etc... is unnecessary and unfeasible) also bernardo's phone died aswell i guess so no more updates and i have no idea why i am replying to you 6 months later but i hope your phone still works ^^ and you are having a good day
[ZenFone 2 Android Development] zenfone selfie:
yeah its working with little problems.

i had to modify kernel and remove offline charging, also removed 1.1 ghz for little cores.

power button is dead, now it's turning on automatically when i plug the charger. and the cpu is defective or degraded i guess? or not, i'm really not sure. works perfectly fine on stock rom but all the custom roms are either bootlooping or crashing randomly if i don't remove that 1.1 ghz from the frequency tables.

after these 2 fixes it's better than ever on this rom. top mounted power button wasn't the easiest anyways. i always used double tap to wake also i can wake the phone with volume buttons.

tried some android 9 and 10 roms but this is by far the most stable one. wish it was at least oreo tho, i really would like to have notification categories.
[ZenFone 2 Android Development] andhikaprstya12:
Im sorry its the first time i was going to costum ROM an android. i have an issue why i cannot unlock the bootloader its says like at the picture. Ive been already update my firmware to the lastest version (Version WW-4.21.40.311) im having Z008 (ZE550ML)
[ZenFone 2 Android Development] zenfone selfie:
servers are down. you can't use the official unlock tool.

but i was able to install custom roms with locked bootloader i don't know how... it just worked like it was unlocked. no errors or anything like that.

also there was an unofficial method somewhere in this forum.

i was on a custom rom when i checked it with adb fastboot command

Hi, has anyone got Pokemon Go to work with this rom on Z00A? I had issues with games with other 7.1.2 rom, like games crashed when opened. In this case, it stucks on loading screen, and I got the feeling it's something related to nougat? Thank you in advice
[ZenFone 2 Android Development] str4610:

[ZenFone 2 Android Development] zenfone selfie:
you don't need any patches for groovy, just flash the kernel and it'll work.

i'm using icey cuz i had the source for it and modified it myself to remove 1.1ghz for little cores from the frequency tables. i can't run any of the custom roms with their stock kernels so i can't compare them, icey is my only option.

just take a backup with twrp before flashing the kernel so you can go back to stock groovy kernel if you want.
[ZenFone 2 Android Development] jimjack12:
Thank you so much for the great job.

Unfortunately you gave us bad news .....

Maybe some other developer will give us a hand as there are still a lot of people using this device.

Thank you and best of luck

Local

New builds are on the way. Several security patches have been merged, some others are waiting to be fully merged by the LineageOS team (which we use as a base).

Please be patient if download links doesn't work, builds hasn't been finished and will be up in the next 3 or 4 hours.
[ZenFone 2 Android Development] zenfone selfie:
i won't be able to update for a long time since i don't have the device but thanks for keeping this phone up to date. today i gave it to someone else and he's using it as a main phone with groovy now. he's not a tech savvy guy so i can't even guide him to update lol... just rooted and installed magiskhide props config to pass safetynet just in case then locked magisk so he can't mess with settings he doesn't know. using a modified icey kernel since i had the source code for it, removed 1.1 ghz for little cores cuz its defective or something, was boot-looping with the stock kernel. also i modified that kernel to disable off-mode charging and boot when you plug the charger cuz the power button is dead. this phone also had a battery and screen replacement. i did my best to keep it alive and it was my secondary device till yesterday. still usable for daily tasks. tried almost all the roms but i think groovy is the most stable one, not having the notification categories is a bummer but it wasn't a big deal for me since it was my secondary device and probably that guy won't care either. i don't think he even knows about the notification categories lol. i tried the newer roms it was a fun experience but i choose groovy for active daily use
[ZenFone 2 Android Development] stingbandel:
Thank u for keeping this decice alive. I really appreciate all your helps…
[ZenFone 2 Android Development] StrikerFX:
Good Morning. Guys, I have a zenfone 2 ze551ml, with the aokp rom installed. I want to remove it to install the groove, but I haven't dealt with it for a while. In my case I just follow the steps of the option to install the rom? My zenfone 2 is not reading sd card and i think this aokp rom is the problem because i always had trouble reading sd card with it. When I do the wipe process, can I play the files on the zf2's internal memory by the pc using adb?
[ZenFone 2 Android Development] bernardobas:
If the external SD issue is related to AOKP then you should be able to read your SD under recovery. If it's some kind of hardware issue it won't work on any of them.

Having said that, and assuming you have a compatible recovery, you can even clean flash the rom without using your external SD or ADB. There's no need to wipe internal storage. Just place your ZIPs (rom, gapps, magisk, etc) in your internal storage, wipe dalvik, cache, system, data and flash rom, gapps, magisk, etc.
[ZenFone 2 Android Development] StrikerFX:
Got it, I did the test for recovery and really it still doesn't recognize the sd card, so it's a hardware problem. I will take you to a service center to get it fixed. But I'm going to use it right away and install the groove, the bootloader is mm, the twrp is version 3.2.3-0, will this version work without problems?
[ZenFone 2 Android Development] bernardobas:
IIRC there were issues witn MM bootloader, you should downgrade to L.

I'm using this TWRP version: https://dl.twrp.me/Z00A/twrp-3.3.1-0-Z00A.img.html
[ZenFone 2 Android Development] StrikerFX:
To do this, just follow the steps in the sub-item "Upgrade bootloader and install recovery"? Or do you talk about reinstalling stock firmware, with android L? If so, what is the procedure for reinstalling stock firmware? I don't remember what the process was like anymore, as I haven't used Zenfone 2 for years, it's with my father now.
[ZenFone 2 Android Development] StrikerFX:
I used the indicated method for installing the groove, I went back to the stock firmware, lolipop version. I used bat to install the bootloader mm, brick my ze551ml, I just can't get back to the lolipop version through xfstk. I don't know if it was a bug that caused the problem, but this method indicated on groove's website doesn't work.
[ZenFone 2 Android Development] bernardobas:
Sorry to hear that. But that's exactly the same process me and everyone else followed.

[ZenFone 2 Android Development] Iyan Mulyadi:
just use as is, this rom is quitely good, google apps, whatsapp working and can be updated as is, and for online game just like mobile legend too, but not recomended for online shoping because they will not permit to loging in you (sorry dev)

feel free to try another rom that fit with you
[ZenFone 2 Android Development] androider999:
Hi everyone.

Phone: ZE551ML 2GB RAM WORLDWIDE model

Firmware: Latest last ASUS official from 6.0 release

Bootloader: UNLOCKED

Recovery: TWRP 3.2.1

Magisk: NONE, Boot is clean

xposed: NONE

I just want to say I love this ROM. It really is the best option as a last, almost recent security updated ROM. It's fast, featureful, and since it's Android 7.1 there's way more app support.

I really want to use this ROM and phone, but there's a huge problem: I cannot make or receive normal calls. When attempting to call any number, the dialer will appear and then the call ends after 10 seconds. I can also see if data is enabled, that data will change from LTE to H or H+, then back to LTE, then to H or H+.

Here is all the testing I did:

Tested SIM and calling on another LineageOS device (Android 8, Motorola brand). Works perfectly, calls come in and go out, no problems.

Tested with latest available of: NutOS, Mokee 7.1.2, and lineage-14.1-20180120-nightly-Z00A-signed. same problem. No calls in or out. I did clean flash, TWRP wiped /system then flashed a ZIP.

Tested in SIM 2, SIM is recognized, but the provider has no 2G service.

Forced to activate on the specific Mobile Network provider in Settings.

Changed to 3G, rebooted, problem persists. Changed back to 4G, rebooted, problem persists.

Installed ASUS ZenUI, ASUS Contacts, ASUS Calling Screen. Didn't help

Installed Simple Dialer from F-Droid, didn't help.

Here is what works:

Everything normal operations wise. Clock, NTP, networking, internet, music, videos, Youtube, Games work, basically all apps I want work. Even apps needing GSF or Google Play Store works (just like my moto without MicroG). Basically just like a normal phone. It's super fast, slim, lightweight, it's awesome awesome awesome awesome.

I CAN send AND receive SMS and MMS text messages on the SIM card, in SIM 1. Works without issue.

I CAN connect to full LTE 4G data networking, works no problems. I can also connect to 3G, no problems. APN is correct.

It is really a confusing situation. It is down to something in software I will say then, because if SMS, MMS, and LTE Data work, but only calling does not (and only calling not working on the Zenfone, not on other phones), AND the issue is present with multiple different ROMs (although they were both NutOS lineageOS based)

I had the screen and battery replaced recently but I don't see how that would cause the issue here. I think calling worked before the screen was replaced, with this ROM, but I can't remember if I tested. Could there be a part inside that was damaged during repair, some kind of antenna? It doesn't make sense because LTE Data and SMS MMS works.

I hope someone has a solution. thank you!
[ZenFone 2 Android Development] bernardobas:
Iirc that was a common issue when coming from Android M. Thats why I used to recommend this installation procedure: https://groovyandroid.github.io/installation
[ZenFone 2 Android Development] androider999:
Thank you. Yes it seems I have this package downloaded. I am just hestitant flashing "random" core files like this. I think what I did was follow the steps in the shell script, but using 4_xx_40_352 files as that's all I could find for MM that came from an official image file.

I did a fastboot flash of the commands in the shell script, everything seems fine. I am clean wiping and flashing the Groovy zip now.

EDIT: Sorry to just edit but I wanted to make sure this was visible. Calls are still not going out or coming in unfortunately, after doing the previous step.

@bernadobas , do you have another suggestion? Will I need to downgrade back to 5.x, up to 6.x with your upgrade zip, then flash Groovy? Or is this not going to work>?

I do not want to install GApps if possible because every app I use daily doesn't need it.

Thank you!
[ZenFone 2 Android Development] sergkarn:
It was also 4.21.40.352 and before I installed Groovy I had to first rollback to L with such firmware UL-Z00A-WW-52.20.40.196-user.
[ZenFone 2 Android Development] androider999:
Thanks, so you had the same issue?

And so, in my case, I need to do the following then?

Downgrade to 52.20.40.196.

I also have the full package for 2.20.40.206, is that safe?

Can I just downgrade bootloader files, or should I flash the whole package?

I assume downgrading will wipe out custom recovery, but not relock system right?

Upgrade to MM BL with Groovy upgrade package

Clean system wipe, flash Groovy

Please let me know if that sounds good. Thank you very much!
[ZenFone 2 Android Development] sergkarn:
No such problem arose because I first returned to L.

I had a stock MM 352 installed and rolled back to L 196. After that I installed Groovy and there were no problems with the sim.

I don’t even know how to safely rollback to L in your case.
[ZenFone 2 Android Development] bernardobas:
Just follow the steps in the link I sent.
[ZenFone 2 Android Development] androider999:
unfortunately APK unlock doesn't work :(

Gave me an error, and said it could be network related. I used my LTE data, so no DNS blocks were in place. Firmware was 5.0, UL-Z00A-WW-2.20.40.206-user

I have given up at this point, I spent all of today trying to get this sorted. And yet even with 5.0 image and firmware, I still can't make calls. So either something was broken when my phone got repaired, or something with my provider changed. I don't have another SIM to test with right now, they are expensive here.

I will try to resell it to some interested dev, or keep it as a VOIP only backup phone in the future after reflashing groovy. And for a replacement I am looking at used Motorolas because of official Lineage support... when I unlocked and flashed my older Moto it was 1-2-3 and took an hour... unlock, TWRP, lineage, magisk, xposed. done

This method allows downgrading even from 7.x custom ROMs to or from 6.x to 5.x

Highly recommend flashing TWRP for easier ZIP installing.

fastboot flash recovery twrp.img

Reboot into recovery

Go to Wipe section system, dalvik/cache, data, one other thing

go to mount at main menu

unmount /system

now open UL-Z00A-WW-4.21.40.352-user.zip in WinZip or WinRAR or something that supports modifying the ZIP

go to META-INF > com > google > android

Open updater-script to edit it

Remove this line:

((getprop("ro.build.version.release") == "5.0") && (greater_than_int(getprop("ro.build.date.utc"), 1462294000))) || ((getprop("ro.build.version.release") == "6.0.1") && (!less_than_int(1498147725, getprop("ro.build.date.utc")))) || abort("Only Android 5.0(newer than 20160504 version) or Android 6.0.1 (older version) can upgrade to this version");

Save the updater-script inside the ZIP, or manually update the ZIP

Then adb push UL-Z00A-WW-4.21.40.352-user.zip /sdcard

then go to install, and install the ZIP

Wait because it takes at least 10 minutes.

Next to downgrade to 5.0. One option is unlock bootloader with another method than APK, then reflash TWRP. Wipe system, unmount, install UL-Z00A-WW-2.20.40.206-user.zip

(I tried this and after doing a 5.0 install, then installing groovy, calling still didn't work. maybe because i mixed MM stuff for the non APK unlock method)

Other option is to reboot into recovery from the 6.0 system (adb reboot recovery) then do

adb sideload UL-Z00A-WW-2.20.40.206-user.zip

from your PC over USB

It should downgrade relevant files so you are only on clean 5.0 files.

I could not do APK unlock, so i'm not sure what else to say here. but this gives some ideas that a downgrade can be done. Phone is on 5.0 now.

Ive got 2 ZF2's 4GB flavor, in perfect working order.

Super fast, 8jstalls anything just as quick as my Snapdragon 855 phone does!

The sad thing with owning an Intel processored phone is, and any Dev will tell you the same, regardless of phone or tablet maker.. Those uptight wankers, even after the chip is discontinued for the better part of a decade, NEVER RELEASES KERNEL SOURCES!!

With the unbelievable amount of e-waste generated yearly due to stupid tactics like this (Apple being the BIGGEST offender here), it's hard to even comprehend WHY a major chip producer would not release sources WELL AFTER the discontinuation of said chip, right?

So, development fell off for this little powerhouse of a phone rather quickly unfortunately, as is evident by the very few threads of development, and original development.

I mean, it's much less powerful cousin, the ZF2 Laser is STILL being actively developed with Android 10 AND 11 ports running on the Laser, but without kernel source, I guess it's difficult, if not impossible to advance a phone with a closed source lollipop kernel😉😅

But, the few ROMs still available work better than the crummy stock interface, that's for sure.

There was even a kernel tweaking script floating around that gave some 20 to 25% better battery life, while being far more responsive... I wonder if I still have a copy of it buried in my NAS... Hmmmm ..

IMHO, as a guy who's had a few ZF2's,

The Dev that did RussianBear ROM, or something of that nature for the title, his final release is what I run on my ZF2.

More features, better response, better battery life than stock.

Hope this helps!

I flash Groovy on my Z00D and it successfully booted up.

But I can't flash Magisk v23.0 in twrp. It stuck on "mounting /system" for a while and failed, showing "unable to detect target image".

I extract the boot.img from ROM zip file and try to patch it using my other rooted device (using Magsik v23.0), but also failed, says "unable to unpack boot image".

Is there any solution or I have to try older version of Magisk? Any one success in rooting z2 by Magisk with Groovy installed? Which version of Magisk is?

Big thanks!

You can refer this article as below:

Signing boot images for Android Verified Boot (AVB) [v8]

Various Android devices support Android Verified Boot (AVB). A part of this is more commonly known as dm-verity, which verifies system (and vendor) partition integrity. AVB can however also verify boot images, and stock firmwares generally...

xdaforums.com

Just

1. Install Magisk.apk

2. Install Magisk .zip by TWRP, then

3. Install the file, VerifiedBootSigner.zip, from the above link.

You can restart system successfully and get root authority.
