Good morning everyone,
I would like to downgrade from LineageOS to Stock firmware for my asus zenfone 2 ZE551ML?
I made some research but i am afraid there is not a clear topic about that.
I would like to downgrade to an stable stock firmware (LP or KK). With LineageOS , my battery is draining too much and i can not use my phone for a day for example.
Thanks for your futurs answers.

Do you want to completely wipe and go all stock? If so, the asus flash tool and the appropriate raw file is the best way to do it. If you don't mind a custom stock based rom, then I'd suggest Borets ROM. Just wipe and flash.

Thank you for your quick reply !
Yes i would like to go back to a stock firmware, a stable one with a very good battery life on the ZE551 ML model. Could you please advise me about the asus flash tool? Indeed, i remember that when i flashed the LineAgeOS , i completly changed the bootloader. I followed this topic: https://forum.xda-developers.com/ze...rom-official-cyanogenmod-14-1-weekly-t3545692
I wrote this message because i do not want to brick my phone and if other people want to do the same i would like to help them with this topic.

Kitkat OTA

I have an m on jb rooted with safe strap is it possible to let it take the OTA to kitkat then root with tr and unlock the bootloader? If it can update will it give me the version that can't be unlocked? If I can't do the OTA how else can I get it on the right version of kitkat?
This has everything you need... Use rsd lite to upgrade to kk make sure you upgrade to 182/183.46.10 so you can unlock the boot loader
We cannot teach people anything; we can only help them discover it within themselves.
Do you have a link to a download of the kk software? I'm at work looking at this on a phone don't see a link in that thread to it

Read through the thread linked to above and make sure you understand. There have been many people getting stuck at .15 and we don't want you to be one of them!
Firmware for use with RSD Lite: http://sbf.droid-developers.org/phone.php?device=8 . Note that unlike OTAs, flashing with RSD Lite will make you lose your data and your internal storage contents - back up first. Use the 183.46.10 one, and if you want to unlock your BL, DO NOT TAKE THE OTA TO 183.46.15! I SAY IT AGAIN, DO NOT UPDATE TO 183.46.15!!

So flash this file using RSD Lite afterwards phone will be on the version of KK that can be rooted with TR and bootloader unlocked with motopocalypse. Then can install custom recovery. I thank you for your help

Just reread if I understand it correctly I don't need kk just the firmware. . . If I'm understanding it correctly

Huh? The firmware's version is KitKat. You need the full firmware to be on KitKat and unlock your bootloader.
Bonus info: after upgrading to KitKat and unlocking, if you find KitKat's battery performance isn't satisfactory, you can always downgrade back to Jelly Bean using the guide in General section, and because this will not relock your bootloader, you're safe to do this.
If you have any trouble doing the above, read through the guide and other forum posts, and if no answer comes up, feel free to ask.

I wrote that the wrong way. What I mean is the firmware file listed is a 750mb file. For my m8 the 4.4.4 firmware update was only 24mb. This leads me to believe that this file includes a kk rom to go along with the firmware. Read a little more(light bulb went on) I thought firmware and roms were always two separate things. . . Duh now I understand why just the one file is needed. I will give this a shot when I get up. Thanks for the help again. Sorry I was asking the wrong question ☺
Thanks andyyan and dbreezy187 all worked out got it done eventually ☺

Ha, he hasn't unlocked his BL yet, so just let him upgrade and do it. After unlocking BL he can still downgrade to JB and maybe even flash CM11 for JB BL (and that's what I recommend).

Thanks again for your help. Now that I'm all unlocked I've seen a lot of stuff about jb and kk bl. I would assume I have a kk bl? Then if I downgrade to jb would have a jb bootloader. Do you have a favorite kk rom and a favorite jb rom? Is downgrading any more difficult than doing all the unlocking? This phone isn't my daily driver just kinda having fun with it ☺ sorry for the barrage of questions you seem waaayyyy more knowledgeable than I. Thanks again

The BL version is the same as your *stock* OS version, so because you now have stock KitKat, you're on KK BL. However, BL version is *not* tied to your custom ROM OS version. You can have KitKat with JB BL as well.
Please do note that some custom ROMs are built for a specific BL (e.g. CM11 has JB BL and KK BL variants).
As for now, it seems that most if not all ROMs for KK BL have minor but annoying issues, particularly in WiFi, BT and GPS, so if you want to avoid these issues, you can follow the guide in General section to downgrade to *stock* JB (in order to have JB BL - this will not relock your BL), then flash any JB BL ROM you want.
I'm always a CM fan so I load most of my devices with CM (see my signature), but if your RAZR is also a secondary device, you can try all the choices out there without worries, so why not?

Didn't know if you had seen this but seems like an easy way to go back and forth between roms and bl's http://www.droidrzr.com/index.php/topic/50096-how-tomobile-downgrader-flash-back-10-09-14-14/ seems almost to good to be true. What do you think?

Hmm, what do you intend to do? If it's flashing something in the AP Fastboot mode (e.g. boot logos, raw partition images) then no ADB. Custom recoveries and the OS itself accepts ADB commands pretty well, provided that you know how to use.

Looks good. Since you have a unlocked BL, there's near zero risk for trying anything (RSD's your best friend when everything fails) - go ahead if you feel adventurous.
Since I don't know what boot logost and raw partitions are don't think I'll need it. I know enough about adb to be dangerous ☺ I can usually bumble fk my way through and get it to work. Thanks again I'll give some of this stuff a shot and have you on speed dial if I really mess up

I need your advice please

HI,
I'd like to buy this ZENFONE 2
But as you see , this one is for China market and the CPU is a Z3560 and not a Z3580
What do you think of this version ?
If I want to use another ROM, which could I take ?
Thank you

That is a ZE551ML Model, so you can flash ROMs marked as FHD, 551ML, and ZE551ML.
It does not depend on the CPU used ?????
Apart from the max clock speed, the 3560 and 3580 are essentially the same chip.
Just be aware you may need to change from CN rom(Chinese) to WW ROM(World Wide). Make sure you read up on this before starting...
Actually there is no good reason to switch from CN to WW if you intend to stay on stock. The CN firmware does not have the bloat of the WW version, Google apps are easily installed and battery life is better.

oops...what are these bloats ? ... how could I change to WW if I wanted to ?
Thx
All the Google and 3rd party apps listed in this post
http://forum.xda-developers.com/showthread.php?t=3174541
These are baked into the system in the WW roms.
Some users have also reported poor battery life when moving from CN to WW.
You will also lose automatic updates.
If you do want to switch there is a thread detailing how to go about it.
If you are intending to flash custom roms then there is no need to flash WW first. Just unlock the boot loader, root and flash TWRP, then follow the instructions in the respective threads for flashing them. Remember to make a backup of of your current setup in twrp first so you can easily return to it if you run into issues.

You can't be on marshmallow and unlock bootloader. Flashong mm relicks bootloader and no unlock yet. So if you want unlocked bootloader you have to downgrade to Lollipop.

Go to asus official website and then go to download section of driver n tools...then download according to your phone's model. Asus provides its official bootloader unlocker in their download section of official website.
Hope it will be helpful enough.

Unlock for MM beta, is it available now?

Hi, I'm using Resurection Remix and lots of custom ROM for over a month, but no one as battery friendly and stable as stock MM. So i would like to ask can we unlock MM by now? So I can flash TWRP and backup, flash and do other things. And safe way to revert to stock 5.0 (Not fastboot flash bom-token blablabla)? I brought my Z008 to service center because of this. If there is a way, plz reply me with a link to that thread(s). Thanks in advance

Yes there is an unlock but it doesn't allow for much. Just use the forum search to find it.

Is that the "2 click one" ? I had tried that before and it didn't work for ze550ml on .69 firmware
And if i unlock sucessful, which root should I flash? The non-system or the normal (Chainfire's) one?
