Update 2.19.40.x for Z00A

and [MENTION=2388665]TheSSJ[/MENTION] , I think we can flash the custom recovery now .. I haven't tried yet but there's "if.bin" in system/etc/firmware :)
[ZenFone 2 General] TheSSJ:
Hey, thanks for sharing the new link :)

But how do you know this COULD unlock the BL? I read somewhere here that ASUS fixed this "exploit"?

Cheers
[ZenFone 2 General] singhnsk:
Does anybody have the link for 2.19 update for ZE550ML? It is not showing the update for me.
[ZenFone 2 General] sarthak96:
It usually takes some time for ota to rollout to all devices.
[ZenFone 2 General] Bnfenix:
Yes, it does. I just did that for the 2.19 update for the Z00A.
[ZenFone 2 General] shakalaca:
got it

After play around with the new droidboot.img I found the risky(?) unlocking method (according to my previous experience in ZenFone 5)

do as root in adb shell:

getprop ro.isn > /factory/asuskey
reboot bootloader

The droidboot will do the unlock process and reboot automatically. You can then grab the old splashscreen here https://mega.co.nz/#!IlMGiZ7I!kepXRFda7cgNPWHQovkCZaMaD2zVF4UufAJT6YEDU3k and enter fastboot mode again

fastboot flash splashscreen splashscreen.img

to replace the ugly white splashscreen :)

Bad news is: you can not re-lock your bootloader again for now (I've tried restore the stock ROM)

Good news is: you don't know if your phone's bootloader is locked or not by reading on screen information or using fastboot :)

So brave XDA people, go and free your ZenFone ! :D

[ZenFone 2 General] ravian29:
wow my bootloader is unlocked, thanks shakalaca you made my day

i made a seprate thread for discussion about bootloader unlock without shakalaca your permission, if you want me to remove it please let me know i will delete it. Thanks
[ZenFone 2 General] sangalaviral:
Can't Asus see through its some other app (aprt from the unlock that it may release) that the bootloader is already unlocked?

Like we can check for the bootloader version and other thing through terminal.

I have no knowledge on it but just being cautious.
[ZenFone 2 General] grorg:
So if I'll unlock bl and break rom in the future I'll have no possibility to restore it or it can be done by flashing system.img and others img's?

And what about OTA's in this case?
[ZenFone 2 General] TheSSJ:
Well, as long as fastboot isn't touched you will always be able to flash stock boot, system, etc. to unbrick it :)

I assume there is some problem with OTA, but cannot prove it at the moment (I am on latest OTA at the moment).
[ZenFone 2 General] ansebovi:
hi great thing,thanks...but how to view bootloader status? how to confirm unlocking?

only by seeing white screen?
[ZenFone 2 General] SpaZzzzz:
hi man.

i just got my phone and i'm not a developer (yet)

but wanted to say thanks and keep up the awesome work!!
[ZenFone 2 General] evo481:
guys one question....are there somewhere the full non-rooted roms for zen2? for example i would like to have the full 2.18 non rooted! im flashing the pre rooted roms and i have trouble with unrooting and updating so i was wondering where are those non rooted available! thanks in advance!
[ZenFone 2 General] lordpipa:
When you reboot bootloader after unlocking, there will be a blue message that says unlocked on that first reboot.

OTA bootloop

Overconfidence killed me

I was on Rooted ASUS ZenFone 2=ZE551ML V2.18.40.1 with superuser 2.46 and Xposed framework installed

On checking System Update I got a message for around 90+ MB 2.19.40.18 update file.

I remembered how I was stuck coz of downloading and updating OTA on rooted ROM

So this time I acted smart.....downloaded the OTA file from the links provided....successfully Sideloaded it...and rebooted

It was stuck at ASUS logo and hose moving circles.... I waited....then powered off....Went to recovery and Wiped cache (It took very long around 10 min)...but successfull.....Rebooted.... Stil ASUS logo and those circles........ waited for very long...hoping it would boot.....phone got hot...but still stuck

Now I know I m in a thick soup......Ordinarily I would just sideload the Stock V2.18.40.1 from AUS website and then restart and then sideload the update.......root with one of the methods....and will be hopefully good to go (OVERCONFIDENCE???)

But the problem is I have to backup few important photos and data......

Now I can start into recovery but I get an option to only ADB Sideload....... Frombootloader only Fastboot........................ (It's stock recovery :( )

How can I use ADB pull to copy data to my computer if I am stuck in bootloop, and recovery gives only ABD Sideload option???????

Someone please help.....
[ZenFone 2 General] hkdmjack:
Damnit, I'm stuck on 2.15. Trying to update to 2.17 is resulting in an error.
[ZenFone 2 General] katsikoskulo:
Still No OTA update to 2.19 for ZE550ML (Z008)?
[ZenFone 2 General] keepfishes:
Yeah stupid Asus posted this but its an empty promise: http://www.asus.com/zentalk/forum.php?mod=viewthread&tid=14490&extra=page=1

I hope they're not planning to support only the higher end 551ML and leave the rest of us in the lurch... But this may be an early sign of such an occurence.
[ZenFone 2 General] Harfainx:
If you're on 2.18, just sideload the 2.19 OTA.
[ZenFone 2 General] luisoman2000:
no OTA for 550 yet, so no sideloading yet.
[ZenFone 2 General] ansebovi:
my bad i guess,but asked many,they said you cant check it ,..weird but thanks,its time to check myself i guess..thanks again
[ZenFone 2 General] luisoman2000:
from what I've read, you get a white splash screen after unlocking the bootloader.
[ZenFone 2 General] drbobb:
I had the same issue - forgot to unroot before applying update. I recovered by flashing full stock with adb sideload - user data and media storage remained totally intact.
[ZenFone 2 General] fuzzybuffalo:
He was not being sarcastic, where it usually says, in blue, continue fastboot process, on the first boot into bootloader after unlocking, and I don't remember the exact wording, but it said bootloader unlocked or something like that.

Yes, you get an ugly white splash screen, that you can reflash back to stock.

[ZenFone 2 General] samteeee:
@OP

Thank you for this bro, great work.

I was just wondering the "unlocking" process is done all on the PC, right?!!

And if yes, as an "Admin"?

Thank you.

Edit= Unlocked the BL and all went smooth!
[ZenFone 2 General] Wilkij:
Greetings. I'm coming from Nexus devices and am familiar with using fastboot to flash images. But, have not used ADB to sideload firmware. Can someone kindly post a link that explains this process? Thanks for the help, I'm excited that unlocking the bootloader opens a lot of potential for our Asus devices.
[ZenFone 2 General] fuzzybuffalo:
Basically it's just,

Reboot into recovery

Select Apply update from ADB

adb sideload file.zip

but see section 4 and click show content for flashing your zf2

[MENTION=1813976]shakalaca[/MENTION] I managed to find out the 2.19 WW OTA link for ZE550ML. The OTA ain't pushed to devices yet so those who want to sideload can do it.

http://fota.asus.com/delta_package/...W_Z008-20150612/WW_550_0601_0612_20150612.zip

I'm sorry if somebody else figured it out before me, but I'm not copying from anywhere. i figured it myself :P
[ZenFone 2 General] troy5890:
Well you know what that means, its time to free are ZenFone's

Sent from my ZE550ML
[ZenFone 2 General] Mononon:
Figured it out.

Though, my computer can't see my phone over ADB. Not sure about that now. Drivers maybe?
[ZenFone 2 General] chooks06:
At the error screen, press and hold power button and give the volume a quick press and release. It should get you past. I've never sideloaded using adb though.

Sent from my ASUS_Z00AD
[ZenFone 2 General] Mononon:
Managed to figure that out right before you posted. Unfortunately, my computer doesn't recognize my phone in ADB, so I can't sideload the update. Can't seem to find a solution for that though. Installed the drivers and updated ADB via the SDK. That's about all I can do to help with that. Oh well.
[ZenFone 2 General] fuzzybuffalo:
When your phone is booted up into the system, does ADB recognize it there?

Did you install both the Asus and the Intel drivers?

If so with the phone hooked up and booted up, go into device manager on your computer and look for yellow exclamation mark, update drivers on that. Should say Android phone or something like that.
[ZenFone 2 General] chooks06:
Alternatively start up the phone normally and connect to PC.

Rename the update file to MOFD_SDUPDATE.zip and park it in the root directory of the external SD card.

Go into recovery mode and it should detect straightaway. I did mine that way.

Sent from my ASUS_Z00AD
[ZenFone 2 General] Mononon:
Detects it fine when it isn't in recovery. Fastboot and system are both fine. It's just in recovery.
[ZenFone 2 General] Harfainx:
Not to insult you or anything, but are you setting the phone to ADB sideload when in recovery and not just trying adb sideload as soon as recovery loads?
[ZenFone 2 General] fuzzybuffalo:
The post above yours was going to be my first suggestion.

The post below yours was going to be my second.

Before you connect your phone to USB, boot your phone to the stock recovery, select update via adb or usb whichever one it says.

Then connect your phone to USB and run the sideload command.
[ZenFone 2 General] Mononon:
Yep, making sure to hit Apply Update from ADB

Doing that. I uninstalled the drivers, though now they don't seem to want to install again. Getting an error when installing drivers when connected to the computer and in recovery. Weird.

Device Manager just shows "Android-Phone" with a yellow triangle. Says there's no driver. Not sure what to do. Download the drivers from ASUS, I guess? Not really sure what to do with them after that.
[ZenFone 2 General] fuzzybuffalo:
It probably won't work now that your drivers are messed up.

Use the MOFD_SDUPDATE.zip method posted above, that's how I did mine also.

You will probably have to completely uninstall all drivers and start over for that to work.
[ZenFone 2 General] Mononon:
That's not a sustainable solution. I've uninstalled the drivers. It simply won't install drivers from recovery. There must be a way to manually install those drivers? I downloaded them from the ASUS site, I'm just not sure what to do with what I downloaded.

Downloaded from here

http://www.asus.com/us/Phones/ZenFone_2_ZE551ML/HelpDesk_Download/
[ZenFone 2 General] Harfainx:
Drop your driver somewhere on your drive.

Control Panel > Device Manager > Find phone (should be listed somewhere) > Right Click > Update Driver Software

Browse my computer > Let me pick > Have disk > Browse > Navigate to driver location > Android ADB Interface

Follow same steps while the phone is in system and select "Android Composite ADB Interface" if you have any ADB or mounting issues in system.

I don't use the ASUS drivers though, so it might be a bit different. I just use the Android SDK drivers.
[ZenFone 2 General] fuzzybuffalo:
You need to unzip that driver file, then in device manager, the yellow mark with android phone, update drivers on it and browse to the unzipped files.

Edit: I'm not sure what you mean by this? It simply won't install drivers from recovery.

Edit 2: Darn it, this Ninja'd stuff is getting to be a habit.
[ZenFone 2 General] Mononon:
I put the phone into recovery, select the Sideload using ADB option, then it says Installing Drivers, then it fails. The error is that Windows can't find drivers.

The thing I download from ASUS has a bunch of files in it. I have no idea which one to use.

For updating OP, the OTA link:

http://fota.asus.com/delta_package/...W_Z00A-20150623/WW_551_0529_0623_20150623.zip

Of course, incremental upgrade: V2.18.40.12 -> V2.19.40.20

I guess it'll work on V2.19.40.18 base too

:silly:

No, It should be a 29 MB file. I was already on 2.19.40.18 and i got a 29 MB OTA.

[ZenFone 2 General] ansebovi:
BTW guys who rooted and in 2.19.40.18, I think you will get bootloop even after update is successfully complete... Please verify if you updated and successfully booted from 2.19.40.18 to 2.19.40.20... I seen 2 of them got bootloop
[ZenFone 2 General] Val3r10:
Double checked now and both links work fine when downloading. Zips are integer too. Have you tested the downloaded zip ?

I definetely guess it's much convenient to unroot and reverting to stock recovery (as said in the TWRP thread) before applying any update.

About bootloader unlock, I don't think it's an end-user reversible process, by now

Thanks for the advice.

I am on 2.19.40.18, rooted by the "Method 3", that should be safe with OTAs.

Neverthless, as said, I'm trying to unroot before updating.

Or, did you experienced bootloops on unrooted phones ? What about unlocked bootloader issue ?

[ZenFone 2 General] chobztopz:
You could make your own flashable zip update, because every body has their own style (rooted or no, deleted some system/app or priv-app, some modding). But I will help to show you how easy to make update via trwp flashable zip by yourself (especially pure stock ROM) . You dont need to unroot, uninstall busybox or xposed again

But first of all, I must ask for permission to [MENTION=2491106]Harfainx[/MENTION] because until now, thanks to him, I'm using his ROM flashable zip script ( http://xdaforums.com/zenfone2/development/rom-2-19-40-18-rom-ze551-goodbye-t3144291 ) to update my beloved Zen 2 to the latest updated ROM (right now WW 2.19.40.22)

So [MENTION=2491106]Harfainx[/MENTION] , can I help them about how easy to update their own Zen 2 using your flashable zip and script?

in my zenfhone (z00a) i have unlocked bootloader, root, xposed, twrp.

Can i flash ota using twrp after unrooting, removing xposed and ignoring unlocked bootloader from your links??
[ZenFone 2 General] bhavei:
from 2.18.40.12 to 2.19.40.20 after update do i have to unroot the 2.19.40.20 before updating to 2.19.40.22?
[ZenFone 2 General] fuzzybuffalo:
No, you cannot use TWRP to flash stock OTA's.

You must flash back to stock recovery before installing OTA's.

You can either adb sideload these OTA's or copy them to Sdcard and manually install them.

You can ignore the unlocked bootloader.

I've heard you have to remove xposed, but as I don't use it, I cannot verify this.

See my answer below for unrooting.

It depends on what method you used to gain root.

Only the 3rd method, the One click method, in the Resources thread allows you to keep root before installing OTA's.

All other methods you must unroot first.

If you are planning on unlocking the bootloader, you should do that first.

I've seen three people fail to unlock bootloader on 2.19.40.22.

But have seen it confirmed working on 2.19.40.20.
[ZenFone 2 General] bhavei:
