Blinking dead android - Mac

Hi all

While wiping the cache, my zenfone 2 (551 4Gb) stopped and got a blinking dead android.

Tried the usual power + volume up but still get blinking android.

The orange charging light still works, as the battery. (it stopped for a while )

I've read about adb and fastboot? And drivers.. but can't see how to make it work with my Mac 10.6.

Any help would be most welcome

Thanks T.
[ZenFone 2 General] gabrieltaets:
I had to create an account here just to thank you. After some 6 hours and lots and lots of failed flashes, it finally worked. Thanks!

A tip for some people with blank screen after running XFSTK, what worked for me was running the flashing process without AFT without rebooting at the end, then unplugging and plugging the USB and then reflashing the firmware through AFT. Took a while but it worked!
[ZenFone 2 General] TheSharkWR:
Hi everyone,

I have a bricked Zenfone 2 (ZE551ML). I followed this guide step by step -many times actually- but I didn't manage to unbrick it.

xFSTK process goes through the end ("Success: FW+OS download completed!")

But then no fastboot screen appears, the phone's screen doesn't turn on and it vibrates twice every 1.5/2 minutes.

During the xFSTK download process (after "Continuing to OS...") I see the USB image for a few seconds instead of the 4 colors screen.

Can I try something else? Is it a hardware problem? Any suggestion would be appreciated.
[ZenFone 2 General] gabrieltaets:
During the xFSTK download process you should see the usb image, that is correct. The 4 colors screen should appear after the SUCCESS message. In my specific case, I got the 4 color screen but did not get a fastboot screen. I just continued with the stesps as normal. It did take some time, I think I did the whole process around 30 times before it finally worked. I suggest you just insist on it. Make sure your device has enough charge. When I was having no success, I left it charging overnight and tried again, after some 5 tries it finally worked.

What I heard that also helps sometimes, is allowing it to completely discharge before recharging and trying again. I did not have to try this though. Just keep trying and it will work eventually. Good luck.
[ZenFone 2 General] TheSharkWR:
Thank you for the advices and for confirming that seeing USB Logo is correct.

I've been trying to do this 2 hours a day for the last 3 days and I'm losing my hopes :(

Does it have sense to wait 10/15 minutes (like the guide says) if after the "Complete" message nothing happens and the phone starts bootlooping again?
[ZenFone 2 General] DanielOliveira88:
I did everything in the guide, and it was all good until the xFSTK "SUCCESS" mesage. Got the 4 colors screen just fine in first try, lucky me. But then the device don't go to fastboot mode, it just keep turning on and of, returning to the 4 colors screen. So i did all the process again like 20 times, with other DNX and IFWI files as well, with the same 4 collor screen result.

What exactly did you do after you got the 4 colors screen?

I was trying to go back to the stock rom after the instalation of the Groovy android (https://xdaforums.com/zenfone2/development/rom-groovy-android-t3756429). In the instalation process of groovy there is a step that makes you upgrade the bootloader via fastboot using the files dnx_ze551ml_4_21_40_134.bin and ifwi_ze551ml_4_21_40_134.bin.

This process with xFSTK overrides this upgrage?

Thanks and sorry for my english.

---------- Post added at 03:51 PM ---------- Previous post was at 03:35 PM ----------

Did you try turning it off pressing the power button for 10sec and then turning it on again? This happened to me one time when i was trying diferent DNX ans IWFI, turning it off and on again gave me 4 colors screen again.

Other thing you can try is the DNX and IWFI files from adroid 6.0. Worked for some users.

Read somewhere too that this could be a "ROM" problem, so leting the device completly discharge or disconecting the batery will reset the rom, and it may come back to life.

Nothing works for me after the 4 colors screen, losing my hopes too :(
[ZenFone 2 General] TheSharkWR:
1) Yes, I tried turning it off and back on. Nothing changed.

2) Where can I find the DNX and IFWI from Android 6? I only used the ones linked in this guide.

3) I didn't try the "completely discharge" thing... It's not easy to completely discharge a phone that can only vibrate every 2 minutes :laugh:
[ZenFone 2 General] DanielOliveira88:
2)

3) If you have the tools, open the phone and disconnect the battery manualy.

Other tips I read (all over the place):

- Take off SSD card and all cell chips and try again without any of them.

- Disconnect the cell chip flat cable silver plate right above the battery)

- Disconnect the battery wait a little, conect and try again.
[ZenFone 2 General] TheSharkWR:
Thank you!!! Thanks to the ifwi from Android 6 I managed to access bootloader!

But... Now I'm stuck again :(

If I try to flash the RAW file with Asus Flash Tool, after a few seconds of flashing, it fails with this error:

Flash image failure(FAILED (remote: Can not mount the necessary partition))

Same thing happens if I try the fastboot method. When I enter the command

fastboot flash /tmp/partition.tbl partition.tbl

It fails with this error:

target reported max download size of 536870912 bytes

sending '/tmp/partition.tbl' (2 KB)...

OKAY [ 0.172s]

writing '/tmp/partition.tbl'...

FAILED (remote: Can not mount the necessary partition)

finished. total time: 0.375s

Any ideas?

---------- Post added at 08:07 PM ---------- Previous post was at 07:54 PM ----------

Googling this error returns only 9 results in the entire internet, and it seems that none of the people who experienced it found a solution... It looks like I have to say goodbye to my old Zenfone :(
[ZenFone 2 General] DanielOliveira88:
this is ifwi zip you can extract desired files[/QUOTE]

I´m glad I could help. My Zenfone is still in the 4 collors screen loop.

I never got to the Fastboot step but I read something about "J-Tag" and "Octoplus" to recover the partition. Maybe this will help you research.

---------- Post added at 10:05 PM ---------- Previous post was at 09:45 PM ----------

Maybe this can help you.
[ZenFone 2 General] TheSharkWR:
Thank you, but as I said, I get the error at the third step ( fastboot flash /tmp/partition.tbl partition.tbl ) of the guide that you posted :(

As far as the Octoplus goes... I don't plan on spending money to revive my Zenfone, it's almost 3 years old and I was using it as a backup phone... It would have been nice to save it (even just for the sake of it :laugh:), but it's not vitally important.

By the way I really appreciate your help :)

im having an unknown comman in flashing firmware without AFT. :/
[ZenFone 2 General] princedhamora:
still stuck. some commands faild while flashing raw file using CMD

I was trying to unbrick my phone. Bootloader repair worked perfectly but when i was flashing RAW file using CMD I got error on 14, 15 and 19 command. After chacking in folder i found these files are missing.

Could it be because I used latest raw firmware ? "WW_ZE550ML_4.21.40.311_20170609"

Should I use older firmware given in post and later update to latest one by adb sideload ?

Ok I got my phone working using raw file provided by you but I have few queries.

When I boot to bootloader it shows wrong serial number. Can we repair it ?

Can you please tell me which one is latest Lollipop Firmware ?

Can I update to latest Marshmallow firmware right after updating to Lollipop ?
[ZenFone 2 General] sanzijs:
Hi, the exactly events described by Kuromeshi happened today to my 2-years-old zenphone. Now, my phone is vibrating each ~3 minutes in a black screen and it doesn't turn on the charging LED when I put the device to charge.

I already started the steps to unbrick it but I got stuck in the "Continuing to OS" part of the xFSTK download: "Timeout to detect the device, make sure to charge up your phone before flashing".

After reading Aioros_Y post, I'm now considering it could have been the battery that went to space and I will buy another one to replace it.

My question is, do the steps I've done so far could have erased any data from the phone? I'm worried I didn't try a new battery at first and now I could have messed up with all my data :confused:

Thanks in advance.
[ZenFone 2 General] sukhwant717:
just skip the fastboot erase data command and don't use AFT
[ZenFone 2 General] sukhwant717:
Yes you can sideload latest firmware.

if you don't see serial number then you can correct it but don't care much about serial in bootloader see in setting>about if there is correct thats fine. if no then root the phone and edit the serial file in factory folder.

if EMI is also gone then use intel phone tool

Same HARDBRICKED zenfone 2

Hi friends,

I have the same kind of situation. My asus zenfone 2 ZE551Ml 4+64 GB bricked while I foolishly tried to install stock Marshmallow thru TWRP recovery on a rooted (unlocked bl) running lollipop. It stuck of flashing splashscreen. I left phone for a while and found it in a dead state after about 40-45 min.

Now it has only black screen, NO display, NO logo, NOTHING except it vibrated every few min.

My PC makes connection sound when connecting phone with USB cable but it is not detected at any level, Neither it shows under intel sco (device manager), nor in ADB and not even in my computer.

Tried xFSTK but it never detects the phone.

Any help will be highly appreciated.

Thanks to everyone with any help.

Syed

Hi sir! can you help me? i followed every instructions but when in "Continuing to OS" it stopped and make 20 attempts. i tried many times but it always skipped the os part. what should i do?
[ZenFone 2 General] bs07:
FW+OS Download completed. Phone starts but still no fastboot screen.

I am getting a black backlit screen after performing the steps in the main post. I have tried multiple times. No fastboot screen is displayed, just FW+OS Download completed, it showed. I have no idea what can be done in my case. Please help.
[ZenFone 2 General] euphrodil:
Hi Guys.

I followed the instructions , well, for the fastboot. my phone rebooted but then it's stuck with the logo asus and a loading logo than has runned for more than 10 hours. so i can't do the ADB section. but i seem not able to reboot in bootloader mode . If i press and hold volume down + power button, the phone will just not open. And if i just press and hold power, it load but won't go further than Asus logo with the loading logo...

Anyone has an idea?
[ZenFone 2 General] euphrodil:
Ok. Thanks. Everything works now. you did a very good job with this tutorial
[ZenFone 2 General] sukhwant717:
are you using windows 8 or 10? if yes disable driver signature enforcement and install xFSTK drivers. note after reboot signature enforcement turns on automatically. so even if you previously turned off turn off again.
[ZenFone 2 General] sukhwant717:
glad to know that it was helpful. feedback/appreciation motivates to do something. thank you
[ZenFone 2 General] euphrodil:
Well, in fact i only did the "fastboot" section and i can finally use my phone. i have not done the ABD section. i received an error, and at this moment just decided to give up. My phone is working on LP. i'll try later if i can successfully put MM on it.

But Thanks anyway. i'm pretty sure the error is on my side.
[ZenFone 2 General] Senkentzu:
Unable to enter in the bootloader after xFSTK

Hello.

First of all, thank you for writing such a in-depth and accurate guide; you gave me hope to save my smartphone.

I accidentally hard bricked my Zenfone 2 (ZE551ML) while trying to remove the TWRP... since then the phone's screen is always black and it keeps rebooting every 1/2 minutes, and it doesn't even show the battery indicator when I try to charge it. I followed your guide but I'm stuck at the unbrick process with xFSTK: the program say "FW+OS download completed" but I still can't see the 4 colors screen because the smartphone reboots itself and then is back to the previous situation. The only thing I see is a usb logo for 2/3 seconds after the xFSTK procedure, before the phone's reboot (I already tried with the Android 6 files unsuccessfully and I'm sure that is not a battery issue because the smartphone was working fine two days ago; and also on different computers).

Do I have any option left or should I say goodbye to my phone forever?
[ZenFone 2 General] princennamdi:
I am also facing the same problem as you.

please help
[ZenFone 2 General] princennamdi:
:cowboy:

I have succeeded in getting passed this stage

I uploaded the files i used to flash my ZE551ML

https://www.dropbox.com/s/gmrobfghlfgdo4b/ze551ml_Files.zip?dl=0
[ZenFone 2 General] Senkentzu:
Uh actually after trying with these files things got even worse Lol ... the phone even stopped vibrating and showing the USB logo, and on top of that the procedure with xFSTK stopped before reaching the "OS" part. Luckily I was still able to flash back the previous ifwi and FW DnX files and now I'm back at my previous situation.

Perhaps is my fault, I don't know... did you try something different than this guide?

Thanks for the help anyway, really appreciate it:)

Recovery error

First of all thank you! I bricked my phone trying to root it and this procedure brought it back to life!

I'm now at the last point of the guide and I'm trying to flash the new firmwares, first L then M, but I have no recovery mode! When I go into recovery, a broken android with a red triangle appears, and below it "Error!". I reflashed only the recovery (recovery_sign.bin) but nothing changed. I read on this thread that it's a common problem, but those who resolved it didn't write how they did it, so I'm at a loss. Can anyone help me?
[ZenFone 2 General] chooks06:
When you see the dead Android, did you hold power button and tap volume UP to get to recovery mode.?
[ZenFone 2 General] Gaber92:
I have no problem in going into fastboot mode. I have a problem with the recovery mode.
[ZenFone 2 General] chooks06:
As far as I know, when selecting recovery mode, the dead Android appears after power button is pressed. Then, press and hold power button and press volume UP. The recovery screen should come on, unless you're saying that nothing happens after you did that., In which case I'm sorry I have no solution.

Cheers!
[ZenFone 2 General] monster_fire:
Thank You

My phone suddenly bricked, I try using ASUS Flash Tool, it come with error message say "Check the detected serial number failure (not found the device of "123456789ABCDEF") then use manual flash the RAW, my phone back to work now.

You save my life, thank you so much
[ZenFone 2 General] Gaber92:
Yes, I meant that nothing happened while in "recovery". I haven't found any solution to this issue, but I managed to upgrade my phone to MM by just pasting the .zip firmware into the root folder and letting the phone do its thing. Thanks anyway :D
[ZenFone 2 General] chooks06:
Oops. My bad.

Anyway, great to hear it's up and running again.

Cheers!

have a very nice day

[ZenFone 2 General] princennamdi:
can you upload the files you used? the dnx, ifwi and droidboot
[ZenFone 2 General] sukhwant717:
Thats Quite a journey bro. nothing could be more pleasing than knowing that post was helpful don't forget to hit the thanks button.

one more thing, i believe your old original battery is still usable. just put it in device and charge it for an hour with original charger or any quick charger available with you.

and if you need any part always order from aliexpress app from china. it takes little longer time to reach. but its worth it. products cheap yet good quality.
[ZenFone 2 General] sukhwant717:
better stick to the originally provided in post. or extract from latest MM firware and replace dnx and ifwi. you can not change droidboot file.

Sup! for the Xfstk I used the files provided, for the fastboot part the RAW image I used was the WW_ZE551ML_2.20.40.206_20170627.raw, you can get it from this other xda post:

xdaforums.com/zenfone2/general/z008-z00a-z00d-z00x-raw-fw-collection-t3448966

Did you get to the 4 tv colors part?

Yes it was lol! Thought I'd never see this guy alive again, I didn't expect to have it working as new, really love this phone, it's tough as **** also, I dropped it a couple of times and the screen is like made of titanium lol, had a really scary moment the day after it came back to life, it splatted with all the screen onto the floor, expected the worth and nothing, good as new (barely visible scratches of course but never cracked)

Thing with ordering outside is that in Argentina we have to make some bureaucratic stuff to be able to import, I bet it sounds ridiculous but well, If I ever make them I'll take that into account, thanks!

Thing with the battery is that it was having odd behavior like shutting down at 45% or turning off when I tried to take a photo with less than 20% of battery, but yeah maybe it still works, I'll leave this guy in peace for the moment lol! Thanks again <3!
[ZenFone 2 General] daymbeg:
After installing the drivers properly and connecting the phone while holding volume down, it doesn't stay connected. As long as I hold the volume down the pc makes hardware connected-disconnected sound constantly. Also the number showing connected moorefield devices in xfstk downloader fluctuates between 1 and 0 as the phone can't stay connected. Is this a hardware failure? Is there a fix?
[ZenFone 2 General] lucianoinso:
Sup! It's not easy to notice when but you have to really make sure the phone is powered off before doing the volume down and power combination, I checked by watching the device manager, if it's connecting and disconnecting wait for 30 seconds till it's normalized, power off pressing the power button for 10 secs, wait a bit more, and only there try the volume down and power just one time, I check with the device manager in the Intel SoC category, hope it helps
[ZenFone 2 General] HungNgocPhat:
I has unbricked my Z008 3-4 times before with xfstk, but this time I can't.

When I power on my Z008, it shows the splashscreen (with Asus logo and intel logo), then it reboots, and show the splashscreen again, then reboots... When I plug the cable in or press whatever key combinations, the same happen. So I can't have it recognized as "Moorefield" device normally.

I can't enter fastboot or recovery mode.

Between reboots (the short time when it power off and power on again), xFSTK can recognize it as Moorefield, but Device Manager just "flashes" and doesn't show any Moorefield device. That means the PC can recognize the device as Moorefield, but the time is too short. How can I make my PC keep recognize it as "Moorefield" device? The strategy "hold volume(-) button and plug the usb cable" doesn't work.

Thanks in advance

Need help, plzz!!

I used this process to unbrick myphone 3 times in the past... But this time I'm failing to do so. What happened is in xfstk it was downloading, but device was disconnecting in the middle of the process cause my battery died (it was old and unable to hold charge for long). So i waited for the new battery to arrive from AliExpress. Now after i put the new battery in, my phone started in the fastboot mode(pic attached), but doesn't take any fastboot commands. Doesn't show up in asus flash tool.

Tried to do the whole unbrick process again, now there is no moorefield in device manager so xfstk can't find the device!

Can someone give me a solution for this plz?
[ZenFone 2 General] subotaiBr:
"

First of all, thank you very much, I had to change instructions a little bit (but with information I collected in this and other topics), but it worked like a charm.

I had the same problem that [MENTION=7088287]marcusvrbrito[/MENTION] had two years ago and it was sugested then that his problem was with emms. But it was solvable just using a different IFWI file for xFSTK, I used the one I found in ASUS page with last ROM UL-Z00A-WW-2.20.40.206-user.zip. Just extracted IFWI.zip from this file and then extracted IFWI file for ZE551ML. Doing that all problems with fastboot commands disappeared, no more "GPT command failed" or "Too many links" errors.

Two years from the problem is a long time but as no one had a solution to him and it occurred to me I felt like sharing the solution.
