As I searching for best solution for this case (Brick from Lineage OS) I mention on boot part then

1) I told the difference of flashed files between ZE550ML(Nothing no boot) and ZE551ML(Bootable but myphoneZE550ML)

2) May I recovery boot part of zenfone2 by this xftsk downloader?

3) On zenfone5-6 (They are older model than us talking about deep brick about emmc part I don't know is that relate or not?)

after I made dicision to go to lineage OS I flashed manything for 6.0

Maybe I changed or flashed something without awareness.... Specially on boot part.... The reason that I struck on looping cuase my phone doesn't boot into 4 Strip colour as usually. I get only Continuing to Os...

reconnecting to device - attempt #1

Until

reconnecting to device - attempt #20

Apparently , xFSTK is the lowest level flash to begin to correct everything then raw wipes and rewrites partitions judging by onscreen flashing cmds on phone ;)

Clutching at straws here...but do try..

Try downloading Asus firmware for M, the one 550 is based on in lineageOS , for example .134 M is for 551 in lineage.

Extract firmware , extract ifwi zip , select the two files from it in xFSTK ;)

And attempt to flash in xFSTK .

Some people have succeeded in flashing those two files and booted into their old bootloader , not the temp bootloader that comes with success of possign.bin.

Good luck ;)
[ZenFone 2 General] sangbuana:
I bricked my Z008D when flashing stock MM from LineageOS via TWRP but managed to unbrick it by following the method in this thread. What I did a bit different is when using xFSTK, I just pressed the Vol- button and then connect the USB cable. Device manager showed Moorefield device connected but flashing xFSTK failed. So I left my phone connected to the PC for about 45 minutes while attending to house chores. When I came back to the PC and flashed via xFSTK, it was successful.
[ZenFone 2 General] timbernot:
Yes, this did happen to me at one point , I put it down to PC speeds and communication between the two devices ,allowing both to settle down to sync , when phone was previously in blank screen vibrating , rebooting recycling stage previously . Although , that would depend on how and what was used to brick.

Good news BTW :)

I was stuck on this step and this comment by [MENTION=7889653]AndreiHeimann[/MENTION] saved me! I didn't notice the black screen was actually fastboot mode... and after reading all posts through page 30 something, I got it solved!

Thanks [MENTION=6511954]sukhwant717[/MENTION] , a lot! Your tutorial is great!

Just a few feedback on it:

1. AFT (AsusFlashTool) - My Symantec Endpoint Protection accused one file as a malware so I couldn't use it... So I did the 2nd option (AFT-less)

2. You could update the first post with this tip from AndreiHeimann, at the end of "Unbrick Process"

GPT Command Error

I have tried both Asus Flash Tool (AFT) other is without AFT but in AFT it shows GPT command failure:crying:

and without AFT i had some "FAILED (remote: unknown OEM command)"

Kindly help me now my phone is still with dead android with "Error!" shows up.

Any steps i have missed out. or why i'm getting this error.:rolleyes:

Help i have tried everything i have read, the serial number displays as 0123456789ABCDEF in fastboot, AFT and in the bootloader
[ZenFone 2 General] jmsrajkumar:
Try flashing the RAW image twice continuously in AFT.
[ZenFone 2 General] :
so flash it once then when its finished do it again?
[ZenFone 2 General] timbernot:
read this about flashing in AFT carefully ;)

Where you can then install AFT again and flash a raw file (twice) - once for approx 4mins when you see ` RESULT=OK` for approx a minute on phone screen(your serial on phone will be 0123456789ABCDEF here). You then close AFT , force close it.

Open AFT again , input raw file again - press vol+ on phone , you will see your serial corrected on pc and on phone here , then start the second flash- then let it finish.

[ZenFone 2 General] :
ok, thanks il have a look when i get home
[ZenFone 2 General] timbernot:
when you have serial 0 to F , you are in temp bootloader.

When you see result ok.

Close it .

Start again.

Press vol+

Your bootloader no longer the temp one and serial , will be corrected.

Incorrect procedure leaves ,

Recovery

Imei

And many probs
[ZenFone 2 General] jmsrajkumar:
Yes, So that now your original serial number will show up.
[ZenFone 2 General] timbernot:
highlighted this problem here many times ,where flashing and letting the first flash finish with temp bootloader is incorrect , causes many probs ;)

https://xdaforums.com/showpost.php?p=70246810&postcount=18
[ZenFone 2 General] :
but i see many result = ok ans only for half a second
[ZenFone 2 General] timbernot:
Yes , you do .

But

Start the flash again , approx 3 mins into flash , it stays on result = ok

For approx 3 mins .

In that time , close flashtools.

Then open flashtools again. Input raw , tick wipe data and press vol + once.

When serial corrects , reflash raw

As it says in the link , if you let it complete first go without correcting serial , you may need to flash in xFSTK again , then correctly flash raw .

Depending on whether you overloaded the phone by incorrectly flashing earlier ;)
[ZenFone 2 General] :
there is no point where is hangs on result = ok

woowww .. i cant thank enough....
[ZenFone 2 General] vic_singh:
Thank you I was able to recover.

How I have a few questions. The reason i got into trouble is because I attempted to root but didn't check my Firmware.

Can I notice the firmware used in this unbricking is Android L but most new root tool are for Android M. I believe the OTA is disable because I don't get an update for the new firmware.

Most of the root tools works with Version WW-4.21.40.223 however this guide uses WW_2.20.40.194_20160713.

Is it as simple as using Asus Flash Tool and install the new firmware downloading from link below?

https://www.asus.com/ca-en/support/Download/39/1/0/13/Lk0Sg1Ulh0Ph49Hl/32/

PS. Any recommended ROM? I'm coming from 3 previous Nexus phones.

Thank You,

You can use if not already used giovix modder tool in general section , bl unlock, flash twrp 3 0 2 1M and root .

You then flash 3 0 3 M4 from OP of lineage - see TWRP download link in lineage :good:

If you select `install` in 3 0 2 1M twrp -- then select `install image ` bottom right , find 3 0 3 M4 twrp img and select it -- reboot to TWRP again after flashing and flash away with lineage ;)

Hi Guys,

Thank you for very good guide.

My Asus suddenly turn off when I was in work and didn't want to turn on. Only vibrates.

Unfortunately in my case this guide didn't help, I was trying and trying, different dfu and ifwi.

Without result.

Every my try end up on the

"Firmware download complete. Reboot to OS."

Nothing help.

My Asus was plugged to different chargers by different cables.

After approx. 100 tries to download firmware and reactivate my phone and 2 weeks reading about it, I've give up and order new phone.

Last idea which left to me was broken battery, but I'm my county nobody sell this kind of batteries.

I've ordered battery from AliExpress.

4 weeks later when battery arrived, I've changed it and my phone magically boots to system.

Battery looks like working but connector is a little bit not fitted and I had to use tape to stop it in place but I have backup my photos which is nice.

So if anyone have a problem with stuck on "Firmware download complete. Reboot to OS." And lost his hope, at least could try to replace battery.

Sorry for my bad English :)

Hi Everyone,

I made 1 huge mistake and I need your help.

In the Asus Flash Tool Process I accidently flash ZX551ML firmware and now in fastboot the Product_name - Z00A and the Variant - Asus_Z00A.

Any suggestion how to fix this problem?

When I attempt to reflash the proper firmware Asus Flash Tool just keep going and going.

Any help would be appreciated.

Thanks,

What is your IFWI version number in bootloader ?
[ZenFone 2 General] vic_singh:
ifwi:0094.1069
[ZenFone 2 General] timbernot:
That is LP temp bootloader gained from a successful flash from xFSTK-- basically you just unbricked then flashed wrong fw :good:

Now you will have to repeat the xFSTK reflash again -- Then flash raw file for LP:good: (twice)

First flash approx for 3-4mins , when on screen cmds pauses on `RESULT=OK` - Close flashtools , force close it !(serial number 0 to F here)

Input raw again, press vol+(serial will be correct here) and flash the 2nd time till it reboots into Android by itself ! approx 8 mins:good:

do not dislodge data cable during above processes ;)
[ZenFone 2 General] vic_singh:
Thank You Thank You Thank You.

The phone would start up and crash so I did a factory wipe via recovery and it fixed the problem.

I also upgrade to ww4.21.40.223. It run good but I would prefer a custom Rom.

I have another question about my Fastboot information screen.

PRODUCT_NAME - Z00A

VARIANT - ASUS_Z00A

HW_VERSION - unknown

BOOTLOADER VERSION - unknown

IFWI VERSION - 0094.0183

SERIAL NUMBER - LOOKS CORRECT

SIGNING - unknown

SECURE_BOOT - unknown.

Does the red lines looks correct?

The 1 of the reason I got into problem is because I attempted to unlock bootloader and install TWRP.

My main goal is to install customer Rom so I don't have to deal with Asus skin anymore.

Thank you again.

Excellent guide!!!!

Excellent guide, the best I've seen for Zenfone 2! It saved me from a problematic installation of Lineage OS 14.1, it corrupted the IMEI of the smartphone and also the mac of the network card and bluetooth together. Following this tutorial, I not only went back to the stock rom and retrieved my entire smartphone, IMEI, network mac and bluetooth recovered. I just have to thank the author of the topic. I already had plans to go back to the LP version with the guide, I got it!

Help! My Zenfone bricks again for some reason. Before it did, I was still using official LOS ROM and when I charge, it did, but didn't gain a single percentage. And when I disconnect it, it still saying that it still charging. Then when I restart, I was greeted with the black screen and vibration. I did the unbricking like I always do when it happens, never fails. But this time, it didn't work. I even use another PC and didn't work.i double check all, and still won't work. And I did the gp value, but it seems it won't stick the cable connection. And log says the looping of sending binary and stuff before it says it failed to proceed to os download. Am I doing something wrong?

BTW, usually I use x64 windows 10
[ZenFone 2 General] sukhwant717:
open your device remove battery connector for a while and connect again
[ZenFone 2 General] SirAnKeKu:
Will try. I'll be back with the result
[ZenFone 2 General] sukhwant717:
make sure to keep it disconnected for some time. let say an hour or two. iit may facilitate xFSTK flash error too. though u can try after 5 min as well if problem resolved
[ZenFone 2 General] SirAnKeKu:
I have disconnected 3 of these connectors. Is this correct?

I was planning to leave it for an hour
[ZenFone 2 General] SirAnKeKu:
After letting it disconnected for 2hours, it ran out of battery. So i charge it for 2 hours. And when i did the xFSTK, it did the same error, consisting the same write _binary kind of stuff all over again. What should i do?
[ZenFone 2 General] sukhwant717:
wipe ifwi on emmc with --wipeifwi command on gpflag 80000100 and 80000000
[ZenFone 2 General] SirAnKeKu:
So i don't have to select any file and only enable gp value. Is that it?
[ZenFone 2 General] sukhwant717:
no no use xfstk in command line interface and use dnx and ifwi file
[ZenFone 2 General] SirAnKeKu:
Uhm yeah. I never use the command line version. Could you tell me the exact command?
[ZenFone 2 General] sukhwant717:
xfstk-dldr-solo --fwdnx dnx_fwr.bin --fwimage ifwi.bin --wipeifwi --gpflags 80000000 --verbose

then gpflag 80000000

then normal flash along with os image with gpflags 80000807
[ZenFone 2 General] SirAnKeKu:
I did with both 800000100 and 80000000 and both of them says the usb error. What now? Is it because of driver or is it because of usb cable or something?
[ZenFone 2 General] sukhwant717:
no its not because of usb or driver issue

try xfstk-dldr-solo --fwdnx dnx_fwr.bin --fwimage ifwi.bin --wipeifwi --gpflags 0x80000000 -v
