Hi, I do not speak English very well, but I'll try.
First go to the website of Asus, and download the firmware .. 184 or this link (http://dlcdnet.asus.com/pub/ASUS/Ze...user.zip?_ga=1.147549438.850793534.1463019251) and put the external SD Card!!!
NOTE: If your bootloader is similar to the image (with the blue letters ..), you just need to step 3 of this my turorial
ht*tp://www*androidheadlines*com/wp-content/uploads/2015/05/asus-zenfone-2-google-howto-1.jpg (remove "*" again^^)
1. Go to this page (https://www.techmesto.com/root-zenfone-2/) and follow the steps of the second method..
1.1 Download Z00A_WW_2.20.40.184 version (https://mega.co.nz/#F!k4MHiAgL!dVuOKeH3eokcwPSNI79ffw)
1.2 Download and extract FlashTools (http://forum.xda-developers.com/attachment.php?attachmentid=3301263&d=1431011927)
1.3 Extract Z00A_WW_2.20.40.184_system_w_root.zip (for step 1.1) and put the "system.img" in the folder of FlashTools together with "boot.img", "droidboot.img" and "recovery.img"
2. Now follow the steps of the second method (https://www.techmesto.com/root-zenfone-2/), from step 7 to 11;
3. Also I was stuck in the bootloader after this procedure... BUT, you need to download this file (the first method): http://www.mediafire.com/download/v6m7n9j0gqins9b/CWM_Zenfone_2_Intel.zip;
3.1 And follow the steps from 1 to 9 (the first method): https://www.techmesto.com/root-zenfone-2/... EXCEPT: The steps include the root (you do not need the root ..)
3.2 When you are already in CWM recovery, only install the firmware 184 (of start.. of Asus) which is in the external SD Card ... and end ^^.
3.3 I recommend wipe data / factory after starting the device first time...
I have helped

If you end up bricked
.and you didn't do any crazy cmds in fastboot mode.
Check my signature

I had been running the MM beta up until this point. I just flashed the .184 RAW file. What made me go back you ask? I figured out that Google Opinion Rewards was not working. I can't live without that.

I can confirm that this method works for ZE550ML on mm beta .69 firmware. I downloaded AFT and flash RAW (Lollipop .149 firmware). Successfully downgraded bootloader unlocked and flashed CM13.
P.S. My status before downgrade was unrooted and bootloader locked and was on .69 mm beta build.

I found a one click bootloader unlock from xda. I downgraded to lollipop .149 firmware and the unlocked bootloader.
Here's the link for unlocking bootloader on lollipop
http://forum.xda-developers.com/zenfone2/general/tool-one-click-bootloader-unlock-root-t3155884
Also there's a method by shakalaca to unlock bootloader in mm beta. I haven't tried it personally because many report that their phones got bricked and most of them could be recovered by xFSTK method.

[Guide] Safely unlock bootloader on official MM

UPDATE: This is now unneeded because threr is a faster way ro unlock bootloader on official MM here, he updated for official MM
Hi, I discovered an unlock method for official MM!! This maybe long but's it totally safe
You need:
Adb and fastboot environment ready PC
LP RAW File
Android 6.0 Beta Unlock tool
Android 5.0 One-Click Unlock tool
First version of beta MM (Z00A) (Z008)
Official MM zip (find it on Asus site)
Thanks to all people upload these links
Just do the following:
Flash the lastest LP via AFT (using raw file given above), wipe all data. If you already on MM, you have to downgrade
Unlock your bootloader using 1 click tool given above
Boot to stock recovery and sideload the first version of beta MM
Unlock the bootloader using MM beta unlock tool above
Boot to stock recovery
Two case here:
Case 1: You can't boot stock recovery
Normally boot your phone (to Android)
Setup it as a new phone
If it shows there is a new firmware, don't update!!!
Enable Developer options, then enable usb debugging
Copy the official MM zip to external sd card
Open command prompt, run adb reboot recovery, accept the adb permission if prompted
After it boots to recovery, select Apply update from SD, then choose the zip file you've copied before
Wait for it to update, it may stuck at flashing splashcreen, don't worry, it's trolling you, may be Asus forgot to update the script
Goto step 7
Case 2: You can boot stock recovery
Sideload the official MM zip (adb sideload <filename>.zip)
Goto step 7
7. Flash this TWRP (fastboot flash recovery <twrp>.img)
8. Root your phone using this method
9. Reboot, if it shows "Your phone has failed verification bla bla..", then you've success. It may reset loop like note 7 in the first time start, don't worry.
9. Enjoy :highfive:
Note: If you're facing with battery problems on MM, factory reset it in Settings > Backup and Reset > Factory Reset > Erase everything
Successfully on my ZE550ML
The warning screen is normal so don't worry and there is no way to fix it for now

Yes, BL will be relocked once you upgrade to MM.
If you want to unlock MM BL(6.0), refer to this thread.
Or you can downgrade to Lollipop referring to this thread. Then your BL(5.0) is unlocked.

Upgrade to MM
Hello folks!
2 week before MM was released i'ved opted to unlock my ZE551ML BL and therefore install twrp and a MM custom ROM..
so here´s the thing i stayed with the ROM for about 3 weeks and honestly..it works very well..but when i knew that 6.0 official was coming out i decided to go back to stock..i did it following manny tuturials avaliable for me to get my BL Re-Locked..but unsuccessfully..so i followed mr_gourav2000 tuturial (http://forum.xda-developers.com/zenfone2/development/stock-rom-ul-z00a-ww-2-20-40-168-t3354526) and reverted to the WW_Z00A-2.20.40.183-to-2.20.40.184 (hopefully i can get the sshot in this post) version...since my BL is unlocked i can´t get no updates..my question is:
Is there anyway to go to MM 6.0 by ASUS with the current status of my phone?
is there anything i can do to revert this??
Cheers to everyone

Have you downloaded the correct build? There are build for MM bootloader, if you flash the normal builds, it will fail and reboot to recovery again. Gapps is the same for all builds
After you install that special build, do not update to newer nightlies, it will fail. For updates, check the link i give you and see if there is a new MMBL build.
About that, here is the post: http://forum.xda-developers.com/showpost.php?p=68542370&postcount=8551

hello friend, I tried to install the CM13 ROM that indicated me and I get Error 7 in TWRP 3.0.2.0, I have Android 6.0 (.134) official and if I can change kernel and flash rom SuperSU but change with a new MM Blows I can not (CM13, AICP, beanstalk ....) thanks for your help!

Run the script again (i gave you in above post). Download the CM13 in that link, not in the OP of CM13 thread. Flash that CM13 and Gapps (Gapps is universal for MMBL and LPBL).
May be you have corrupt download, I'm currently running CM13 on MMBL

I will recommend you to first upgrade your Android version to lollipop with latest firmware version ww-3.24.40.87 .
After upgrading, root your device and after that unlock your bootloader.
For rooting method, search in Asus zenfone 5 forum.
And for unlocking bootloader you can visit this link below-
https://forum.xda-developers.com/zenfone-5/general/guide-how-to-unlock-bootloader-safely-t3562640
After unlocking bootloader you need to flash the TWRP Recovery. You can unlock bootloader and install twrp together in just one click. For that just visit the above link provided.
Now I'm assuming that you have rooted your phone and also your bootloader is unlocked and latest twrp is installed. So now head over to "Android development" forum of zenfone 5 and search for Resurrection Remix 5.8.2 by tank0412. This ROM is stable and also the developer is providing weekly updates.
I hope that this will help you out.

Yes. T00F and T00J both are same.
Just download it from official Asus website.
Just remember your SKU which is ww, tw, or cn.
To check your SKU, go to settings - about phone - and there check which firmware you have officially.
If you have WW firmware then you have to download ww firmware from the Asus website.
Eg. WW > WW
TW > TW
CN > CN

You cannot flash nougat ROMs with twrp 2.8.6 ,.... As you will end up with several errors so better switch to latest twrp I.e twrp 3.0 xx versions by xanwar . after that you can follow juyels method of flashing the ROM .
Download the twrp version from below link .
1:If you downloading zip file then flash through your old recovery and reboot to recovery .
2: if you downloaded .IMG file then flash through fastboot using the below code
Code:
fastboot flash recovery <filename>.img
Link for latest twrp : here

Dear Friends,
Finally, I could successfully installed RR.
Your suggestions are very timely and helpful.
After installation of TWRP 3, RR installed without any problem.
Thank you again, brothers.

From the first time i was not able to upgrade my phone to another new version of Android.
The phone was bought on chinese store with Android version : WW V10.40.47.107 (Android MM)
When i checked availability of new versions, phone showed me no result available.
Then following instructions i unlocked bootloader and then install TWRP as recovery system.
I tried to install updates of ROM downloaded from Asus website using this methods with this results :
installing by TWRP with ROM transfered to internal memory of phone KO
installing by "ADB sideload" command KO
I partially resolved after many attempts updating only to Version V11.41.87.2 (Android MM)
I solved in this way :
i used TWRP installing from file transfered directly in microSD
i extracted from zipped file "updater-script" file that is possible to find in the following folder path :
META-INF > com > google > android
and then deleted this rows :
(!less_than_int(1494697617, getprop("ro.build.date.utc"))) || abort("Can't install this package (2017年 05月 14日 星期日 01:46:57 CST) over newer build (" + getprop("ro.build.date") + ").");
.....
getprop("ro.build.asus.sku") == "WW" || abort("Please use the right SKU for updating...");
.....
and then save file extracted and compress into zip file.
During TWRP install process i got some error updates, it seems connected to System folder/partition update
but at the end i was able to update Android to my phone
I tried to do the same method with an other update Version V20.32.67.25 i got a corrupted System folder/partition
It seems essential to update this phone to use original recovery system. Can anyone give it to me?
Or is there someone who has been able to install updates using TWRP without any error ?
Also after installation I wiped the Boot, System, Data, Cache partitions and then I restored from Nandroid backup done by TWRP.
But the phone did not start at the reboot.
I then had to reinstall the update with the method described above to get the working phone back
Why did Nandroid backup with TWRP not correctly restore the phone?
Many thanks to anyone can help me

There is a link to a rom in this post. In that zip you will find recovery.img. Flash it with adb, like you flashed twrp.
Then you can flash the last M official rom, and subsequently the first and last N roms.
That's the way I did it. I had to end up wiping data, to make it work correctly.
I'm also looking for a Nougat recovery.img.
I wouldn't like to go thru all the process again if there is another update.
Good luck.

i think you need flash full firmware bro ,
1. Download newer version firmware
2. You need Convert system.New.DAT to system.img
3. Move system.img and boot.img to minimal adb & fastboot folder
4. Open minimal adb & fastboot
5. Flash boot.img and system.img

Just to let you know I did this then downloaded each update from Asus website. You have to do it in order ie newest MM to oldest N to newest N. Takes a lot of time but it works. I now have N on my phone.
Thanks everyone for all your help.

After 11 hours trying out finally solved!!!
I originally just wanted to do a factory reset, and swiped then not only data/cache, but unfortunally - because of lack of expirience - also system partition. After that all the problems occured like described above and partitionally in https://forum.xda-developers.com/zenfone-3/help/unbricking-zenfone-3-ze552kl-dm-verity-t3563970 (there was no OS anymore, twrp warned me this every time I wanted to power off, but I couldn't install the firmware again through fastboot neither through twrp -> install zip; have got error 7 or 6).
Afer a lot of fears and hours of trying aroud possibilities above as well as ideas from articles here:

I have finally founded a solution!!! This is in FIRSTLY restoring original recovery and just then flashing the stock ROM. Here the steps to do for it:
a.) Download original stock rom (raw-version!) from https://cloud.mail.ru/public/HuMJ/wEybSNsQA (raw is to flash through AFT - asus flash tool) or from any other source you can find online; official name seems to be "WW-ZE553KL-20.31.49.2-MR2-user-20170620235128-release_raw.zip"
b.) Exctract and move recovery.img to your adb-folder on PC
c.) Boot your phone into fastboot/boot mode, connect to PC through USB-Cable
d.) Run cmd in adb folder, then type in the command "fastboot flash recovery recovery.img"
e.) Reboot and choose recovery mode - now you have no twrp anymore, but the original recovery menue
f.) Install update, which means, original stock from your sd-card.
Be happy!
It would be nice if you could give me feedback, whether my solution was helpful for you, because it took time to write it and hope it will usefull

Boss,
This solutions can work with ASUS ZENFONE 3 ZOOM.........???
I have ZenFone 3 zoom. Already I successfully convert CN to WW Rom by following this introduction ... https://forum.xda-developers.com/zenfone-3-zoom/how-to/transfer-cn-rom-to-ww-rom-ze553kl-t3612990
But, I can't update android nougat any way. I convert system.new.dat to system.img...... And try to flash it but unfortunately that's not working......
Please help me .......:crying:

Yes, I did it with my Zenfone 3 Zoom (ze553kl). So, you have firstly to flash the original recovery - to find, as described, in the raw stock rom zip archive. Or, you can find all original recovery's also here: (not tested by myself) https://mega.nz/#F!p90wgAaY!l1JbJilmAUEKTKWu43pT9w
Copy recovery.img to adb-folder, then flash it in fastboot mode in the cmd with "fastboot flash recovery recovery.img". Also copy the original stock rom with Android N to your sd-card and put it into your phone.
Then reboot your phone into recovery - now you have no twrp anymore, but original recovery. Install now the zip with Android-N-stock-firmware from sd-card. Enjoy!

Boss ,
Thank you very much ...... Your solution absolutely excellent and work very well . I am very happy for your support . But unfortunately I found new problem on my phone ...... After update nougat a white line found on the display......
How can I solved it .......
Waiting for solution.......
Thanks again for your support ........

Glad to hear, that it worked for you as well. About white line I have no idea, but on other pages I have already seen somewhere, that other users also reported about this problem. Try to look at google "ze553kl update white line". You can also search a solution for ze552kl instead of ze553kl, because, as far as I know, the ze552kl (ZenFone 3, without "Zoom") is almost the same device, just with a little worse cam. Therefore, it seems to be longer on the market and to have more users, so there are also more solutions for problems which can occure to this device in the internet. Wish you a good luck!

Very helpful, thanks!
I must've messed something up when I flashed TWRP.
TWRP ran fine, but when I tried to start it up, it stayed stuck at the Android logo.
Then errors popped up when I tried to install the stock rom through TWRP.
I never would've thought or had the guts to restore stock recovery first.
This should get its own thread.
Edit: I think my mistake was unchecking "Mount system partition read-only."

After many days i finally found enough time to try to use your tips.
I tried to convert system.New.DAT to system.img but without success using this program Autotool 3.0
http://www.droidviews.com/convert-and-extract-system-img-and-system-new-dat-files-on-windows/
After this attempt i used a ROM provided by chinese store to flash its content :
system.img
boot.img
recovery.img
Original recovery.img is essential to install other updates.
After that i tried to install other updates recognized directly starting by phone but always without success.
So i have had to install updates using original recovery tool.
Now i got Android 7.1.1 last version installed on my phone but it's impossible to use
TWRP recovery tool.
Obviously it's possible to install TWRP instead of original recovery tool and also possible to make a nandroid backup
but it's impossible to use it to install original ROMs released from Asus and it's not possible
to use to restore nandroid backups.
Is it eventually possible to use a custom ROM ? If it's, which one and possibly compatible with TWRP ?

i solved issue of update, but TWRP ?

After many days I finally found enough time to try to update my Asus Zenfone 3 Zoom to Android Nougat.
To solve the issue, I used an original Rom from the Chinese store because it contains useful files for purpose without any conversion:
boot.img
system.img
recovery.img
I flashed all 3 IMG files.
Recovery.img that it's necessary to get original recovery without which any update can be done.
You must use a microSD and the original recovery tool to be able to upgrade your system.
The problem is that it does not seem possible to use TWRP. It is possible to install it in place of the original recovery and you can do also a nandroid backup but in practice you can not use it to install any updates and restore any nandroid backups.
Is there a custom rom that you can use instead of the original one?

Official site does not have fastboot ROM, those zips are meant to be flashed via stock recovery.

Is there a technical reason why you can rollback to the last month's ROM from the Asus website with the stock recovery? Has the filesystem changed or something?

Dear simply visit any Asus service center they will downgrade it to Oreo, I visited today, and one interesting thing is they don't have any stable update for now . Soon a newer fota update will release.

First flash twrp then wipe everything except sd card and then flash stock recovery and try again

I posted here about the issues I had. I know that at first the problem is the old firmware can't be installed over newer firmware, when I fix that problem the zip package is no longer signed correctly.
Please could you explain why the method you suggest will work.

Yes it's work i done with 2 max pro m2

In case of system update failure the zip file you are trying to flash will be corrupted. (Happened with me many times as i renamed the oreo stock rom to above the build number of the pie update so my phone would treat the downloaded oreo rom to be new .but during the system update after reaching aroung 25 % it displayed an error and the next thing i remember is the zip file getting corrupted) so always keep a backup!
On 25th of april new pie update was released which fixed screen blinking issue.
