Help installing a ROM.zip from ASUS on ZE500KL

Hello all,
I really need help for my ZE500KL. In summary, it stucks on ASUS logo and bootloop. I can't get to welcome screen.
It is not rooted, i've never touched to the original system. I got this problem after an update from OTA. The update was not interrupted for information.
I can get to the recovery menu, can do a wipe data/factory reset, but it solves nothing. Same problem.
I've tried :
- apply update from adb but this stops at 46% and failed with an error like E:failed to verify the whole-file signature
- apply update from microSD but it stops and failed without error message
I don't know if there is another way to fix.
Thanks

Bro go to the asus site and download the whole rom nd flash it thru recovery.
M also had a same problem.
So let me know nd which variant u hav?

Thanks for the reply.
When i said "I have apply update", this means that i've downloaded zip file from Asus website, and loaded it via the recovery but the process stops at 46%.
Maybe it will work for a custom recovery like CWM or TWRP but as i know, there is not a working CWM or TWRP for ZE500KL at this time. Maybe.
For me, the stock recovery don't work for loading the zip file from ASUS. It says something like : Unable to verify the whole-file signature, Process failed

If your device stops at logo this means that it boots into fastboot mode. I`ve had a same problem. You can take this adb driver . After installing you need to put in C:\adb file boot.img from archive which you dowloaded from official asus.com, then run cmd.
Code:
cd c:\adb
and last command will be...
Code:
fastboot boot boot.img
try it.

I tried. It doesn't work.
I proceed like this :
1- I've booted the device in recovery mode, connect it to PC and uninstall the device and his driver in to the device manager. I do the same in fastboot mode
2- I've installed the 15 seconds adb ver 1.43. As it is recommanded, I force install of drivers to "Android ADB interface" for recovery mode and "Android Bootloader Interface" for fastboot mode. At this time, adb detects the device via "c:\adb> adb devices"
3-I've extracted the "boot.img" from UL-ASUS Z00E-WW-12 8 5 106-user.zip from Asus Website
4-No problem to proceed with "c:\adb> fastboot boot boot.img" BUT that's all.
--> The device boots, passes the ASUS logo with the powered by android at the bottom", arrives to the second ASUS logo (the one animated), then there are messages "Android upgrading, optimising 1 of 1 app", "Starting apps", then it reboots, and bootloops .... again and again. I have to take out the battery to turn it off.

Have you tried downloading the full ROM image from the ASUS support website again? (yes, download again and try flashing your device again). Usually when it says something about signature verification failed, it is due to the incomplete download of the ROM image (corrupted), or that it has been modified.
Do report back the results.

I's been thinking to this ...
I've downloaded 3 times the ROM from asus website. The download procees has been interrupted because of internet problem but i was able to resume after. I've even downloaded previous version. I am able to extract the zip file to my computer without error like cooupted file or CRC..
I need to know if other persons have the same problem exactly with this ZE500KL because, i have recently done the same thing with my ZE551ML and i had no problem.

Have you tried flashing the previous updates (software versions) instead? Could be a "bogus" update.

Yes. Same problem with .172

I was been delighted when i see this TWRP for ZE500KL http://forum.xda-developers.com/zenfone-2-laser/development/recovery-twrp-3-0-0-0-recovery-t3319704 and it works,
But my joy was so short.
It says that it was unable to install the ZIP file because the ZIP is for WW_PHONE, and my phone is an OMNI_ZE500KL !!! What is this ? Never heard about it before. What's weird with this AUS ZIP file !!!??

Can you try to ADB Sideload the ASUS ROM?

Never heard about this OMNI SKU before.

If someone else has the same exact phone with you with a different SKU (perhaps WW?), you could try asking him to backup the recovery.img on his phone for you to flash. After that, just flash recovery via fastboot and you should be good to go.

ZE550KL bricked ?

Hi,
I was at work Sunday night when the phone offers me an update, not wanting to lose my data I re-growth that has Tuesday morning during my last round (which takes me roughly 25/30 minutes ). So I run the update and go round when I come back I have the phone on the screen of blocked boot ...
Considering I'm looking since yesterday, I have already tried many tutorials that did not work.
I tried everything flashed like to start from zero but nothing worked. I have every time a message like: failed can't install image not signed OR dtb not found ...
I have access at fastboot and nothing else.
There's way to save this phone I for 3 months or it is good to wedge a table ?
Thx in advance
edit :
ok, i do this
http://www.asus-zenfone.com/2015/10/how-to-root-asus-zenfone-2-laser-ze500kl.html
and this
http://forum.xda-developers.com/showpost.php?p=66894780&postcount=5
and i have now acces to recovery mode
Edit 2 :
http://www.asuszenfoneblog.com/2015/04/how-to-flash-asus-zenfone-2-via-adb.html with the firware Version V13.10.7.1(Andriod M) https://www.asus.com/support/Download/39/1/0/20/KsY29RCpsJ2bea9O/32/
but after reboot i have the message : ERROR : Can't load invalid boot image !
i lose th recovery and i can't flash the boot ( remote dtb not found ) ...
edit 3 :
the phone has restarts with the original firmware but I have so manipulated that I do not know what I did
I remember using the following links : http://www.asus-zenfone.com/2015/09/how-to-flash-asus-zenfone-2-laser.html ans the stock rom for 550KL
when I reinstall the rom of origin, such would not boot and I had to boot the mod_boot.img picture (Flashtool boot mod_boot.img), which launches the phone and now more problem. It remains to remove the root which should be easier than the rest.

@Genux888 This link takes to ZE500KL's firmware downloads https://www.asus.com/support/Download/39/1/0/20/KsY29RCpsJ2bea9O/32/
Your phone model is ZE550KL but you first attempted to flash MM ROM of ZE500KL
Thats why you got error: invalid boot.img and you lost recovery.
I don't know where you got mod_boot.img from. Neverthless, here's the simplest fix-
1. Download ZE550KL's Stock_boot_recovery.zip
This zip contains stock signed recovery.img and boot.img. Extract it and copy both .img files to the folder where you have adb and fastboot files.
Download correct firmware for your ZE550KL of the correct SKU. You can find your SKU on your phone's box.
WW SKU : Download ZE550KL's firmware v1.17.40.1531 for WW SKU only
Let me know if your phone's SKU is not WW
Copy the firmware zip (UL-Z00L-WW-1.17.40.1531-user.zip) to your external sd card.
2. Connect your phone to computer and Reboot phone to fastboot mode.
3. Now run the following commands
Code:
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot oem reboot-recovery
3. Third command should reboot your phone to recovery mode.
Now, in recovery mode-
A) select "wipe cache partition" then select yes
B) select "apply update from sdcard" then select "UL-Z00L-WW-1.17.40.1531-user.zip" and finally select "yes"

Removed, putback battery & followed all steps, successfully installed 1531 rom
Then upgraded to Asus Marshmellow, Everything working.
But when I try to clear data & cache from new recovery I get couple of errors stating unable to mount /asdf & few other things

I did the following-
Input: "Wipe cache partition"
Output: E: unable to mount /asdf (invalid argument)
Input : "mount /system"
Input: "wipe cache partition"
Output: Cache wipe complete
E: unable to mount /asdf
E: Can't open /asdf/recovery/last_log
This shows that I am able to wipe cache after mounting /system (though it doesnt make sense)
I didn't wipe data as I don't want to setup my device again. You may try if wiping data works after mounting /system. Alternatively, you can flash stock 1.15's recovery (download from post #2)
and flash in fastboot mode using
Code:
fastboot flash recovery recovery.img
(assuming you recovery.img file is present in the folder where you have fastboot files)
And, here on XDA, we hit "thanks" good button if a post was helpful to us.

Sorry to reply so late but I managed to unlock my phone has put version 5.0, the update to 6.0, UNLOCK the boot, root the phone and install the TWRP may close 2 or 3 hours after my last post.
thank you.

i really like it when people post all the steps taken and links in their problem posts.
this is great.
(no, that is NOT sarcasm)

The best solution out there for zoold 550kl
This is the best answer for the rooted asus zenfone 2 550kl for upgrading to marshmellow stock .Thank you...

Help
@sziraqui My phone is in a bootloop and I honestly know pretty much nothing as to how to fix it.. I know it's the ZE551KL, but that's pretty much it. Is there any way youcan help me out? thanks in advance

Stock recovery for MM?
Anyone have stock recovery for MM upgrade from LP?

Problem Not Solved
I am Also facing same type of problem but the difference is :
- I am only able to enter fastboot mode only when i am connecting my phone to pc via datacable.
- After flashing recovery.img and boot.img also i am not be able to go to recovery mode..
Can someone please Help..

I've seen you've tried a lot.
I'd suggest you try this... As long as you can send your phone to fastboot and can pc/add your way through you'll be able to unbrick it. This takes a bit of time as you'll be dealing with two huge downloads (system.img and stock rom) but it should do the trick.
Follow the guide here:

The guide at https://www.asus.com/zentalk/thread-80274-1-1.html talks about flashing boot.img first then a huge (1.7GB) system.img second then recovery.img last.
So it could mean the boot.img and system.img needs to be dealt with first before you have any chances of getting your recovery to work.
Follow the steps closely, I've been able to fix a brick with it twice.

NO way to boot into Recovery or Fastboot!!!!!!!!!!!!!

:crying::crying::crying::crying::crying::crying::crying::crying::crying::crying::crying:

[ZE552KL/Z012DC] Canadian Thread - Unlock, Root, Update to Nougat

This thread will be for the Canadian version of ZE552KL, and will be updated with specific info relevant to Z012DC model found in Canada (Canada Computers, Staples, other retailers). It has WW SKU number.
It took me a while and some searching to figure all steps out. I also modified Asus N and M firmware to remove version checks. Without this step - i was stuck with error 7 in TWRP. The only difference between Z012D and Z012DC seems to be in Fastboot and ADB drivers, TWRP recovery, system images seem to work well so far.
Steps:
1. Download Fastboot and ADB Drivers. For me usb driver on ZE552KL Asus download page didn't work. Select "Only install driver", you do not need to update your drivers via DRP.
Fastboot driver (for Vendor VID_18D1&PID_D00D): http://drivers.drp.su/Telephone/Hua...03.00/Huawei-FORCED-Allx64-2.00.03.00-drp.exe
ADB Driver (for VID_18D1&PID_D002): http://drivers.drp.su/Telephone/Leshcat/WinAll/Leshcat-WinAll-drp.exe
2. Save the following files on your External SD Card:
Modified M image UL-ASUS_Z012D-WW-13.20.10.152-user.zip
Modified N image UL-ASUS_Z012D-WW-14.2015.1701.8-user.zip
SuperSU - latest version from here
no-verity-opt-encrypt-5-1.zip. Give thanks to @kaffeine1 , without him - we would all be stuck with black screens
3. Save ADB and Fastboot files on your computer, and extract; give thanks to @snowwolf725
4. Download newer recovery (TWRP 3.1.0) from here
5. Unlock bootloader via unofficial unlock method; give thanks to @snowwolf725
6. Get into fastboot by turning off the phone, and pressing volume up + power. Install recovery that you downloaded in step #4:
Code:
fastboot flash recovery twrp-3.1.0-0-Z012D.img
7. Follow the steps this guide by @kaffeine1 . Skip the steps of downloading Nougat and Marshmallow firmware from Asus site, as you have already downloaded and saved both firmwares in Step #2 . Also skip the last step - do not reboot into Nougat, but go back to fastboot mode.
8. Root Nougat - follow steps under #2 here:
https://forum.xda-developers.com/zenfone-3/how-to/twrp-recovery-3-0-2-root-zenfone-3-t3569926
How to update to the latest version of OS:
1. Go to Asus Site, download latest WW image UL-ASUS_Z012D-WW-14.2020.1703.28-user.zip
2. Extract UL-ASUS_Z012D-WW-14.2020.1703.28-user.zip\META-INF\com\google\android\updater_script , edit, remove first two lines, and put back into the zip file (e.g. using 7zip)
3. Extract from above zip file boot.img , and flash it via: fastboot flash boot boot.img
4. Flash recovery: fastboot flash recovery twrp-3.1.0-0-Z012D.img
5. Reboot into recovery, and flash:
- Firmware that you modified in #2
- no-verity-opt-encrypt-5.1.zip
- Latest SuperSU
- Rooted.zip (from step #8 above)
6. Reboot mobile, and enjoy new version!

I noticed that in some cases TWRP doesn't "stick", and gets overridden by default bootloader. Specific check is essentially useless - just to prevent flash of improper image. Just remove the check in the new FW, or use modified FW that has the check removed. I think in your case you can just re-flash TWRP since your bootloader is unlocked?

I tryed several TWRP 3.02 and 3.10 if a boot imge ... if entered bootloader with volum key + power it says all ok but booting never happens... if i enter bootloader trough adb it stucks until i disconnect and reconnect usb cable. when trying to flash. fast boot returns error not have permision and side load error secttion 7 on UL modified or else footer w

flash modified images through twrp - with links in OP

Well my wife liked the phone so much, that she "kindly requested" me to gift it to her... now she is the proud owner of a canadian vertion of ZE552KL and i got myself a ZS570KL
thanks a lot for all your help.
P.D. : i think she was not happy with the time i was spending with the device.

I know this is going to sound super dumb, but the unofficial bootloader unlock still triggers the bootup message and voids the warranty, right?

This might be even dumber... But my guess is that the official app to unlock boot loader, does more than unlock,
My guess is that it also register with asus mobile, the fact that for your device has been unlocked...

That's what some manufacturers do, like Motorola and HTC. But from back when I unlocked the BL on my Zenfone 2 Laser, I remember that all it did (as far as I could tell) was unlock the bootloader and set a flag in the bootloader that made it say it was unlocked that couldn't be reversed. No need for fancy registration systems when you can just boot up the phone and take a look.

What was modified in your N-image firmware file? There is now a newer version that I'd like to install. Can you provide an updated modified file for version WW-14.2020.1703.28 or give the steps needed to modify it myself?

Updated OP with instructions regarding how to upgrade to the latest version of N - just tested steps myself. Should be applicable to all future versions of N posted on Asus site. Enjoy!

Lenovo K6 without OS

Hi, I already had my phone rooted and with TWRP installed, but I needed to restore my phone. First I did this trough the system, but I noted that a lot of old files still were there, and I went to TWRP and did a wipe, but selected /system and /cache, now I don't have a OS on my phone.
The phone doesn't turn off, everytime I try to power off, he turn on again, and stay on Lenovo logo. The only thing I can acess is Fastboot mode (via Power down + power), I cant acess TWRP trough the phone, but I found a .bat file, that when I'm in fastboot mode, it flashes twrp on my phone and I can acess it . The other problem is that I always get an error when trying to flash any rom. Things like Error:255 or ".zip file not valid". Tried 2 roms and nothing.
Can someone please help me? I would prefer a stock rom for Brazil, but now I just want any rom, dont even mind if it's not stock.

Hi, I already had my phone rooted and with TWRP installed, but I needed to restore my phone. First I did this trough the system, but I noted that a lot of old files still were there, and I went to TWRP and did a wipe, but selected /system and /cache, now I don't have a OS on my phone.
The phone doesn't turn off, everytime I try to power off, he turn on again, and stay on Lenovo logo. The only thing I can acess is Fastboot mode (via Power down + power), I cant acess TWRP trough the phone, but I found a .bat file, that when I'm in fastboot mode, it flashes twrp on my phone and I can acess it . The other problem is that I always get an error when trying to flash any rom. Things like Error:255 or ".zip file not valid". Tried 2 roms and nothing.

Error 255 is caused because you are trying to install a 64bit ROM over TWRP (32bits), you need to upgrade TWRP to 64bit, just so you will be able to install a ROM. Remember that you should use Gapps in 64bit [ARM64]
TWRP: https://dl.twrp.me/karate/twrp-3.1.1-1-karate.img
Gapps: http://opengapps.org/ (ARM64)

I already had this version of twrp, but downloaded anyway and got the same error when tring to sideload a ROM "Updater process ended with ERROR: 255" . I don't know what to do anymore, I tried with 4 different ROMs, also I searched for a method to erase the lines with asserts on "update-scripts" in META-INF, but then I got a "Invalid ZIP file" error.

Try to go back to the 32bits version and erase everything and format the data and return to the 64bit version because here I had this problem it was because of the TWRP that I was using, it was the 32bits version, after that I upgraded to the 64bits version I did not have this problem. Remembering that in the site https://dl.twrp.me/karate/ has two versions of TWRP, the version twrp-3.1.1-0-karate.img is 32bits and the version twrp-3.1.1-1-karate. img is 64bit.

MAN, the ERROR: 7 now could be solved by deleting the lines with ASSERT in "\META-INF\com\google\android\updater-script".
So, thanks for helping me, the problem with 64/32bits worked. I'm really glad that this worked, had stuck for 3 days without OS, now i'm never messing with this stuff again haha.

It says device not supported why??

Dont forget to reboot again into twrp - after flashing 64bit twrp . This is a step that is very important if you will not reboot your phone into twrp after flashing 64 bit twrp then , it will keep showin you the error 255.
So check that .

Use erase the data from wipe option then you will be able to install rom and g-apps.
Every time you will need password, I don't know why but after erasing data you install all files otherwise you need to erase data again and again

I Faced same problem. It's ok that your phone is in weird state for time now. And also possible to recover.
Hopefully you have adb-tool, custom-rom & gapp, twrp.img on your PC.
1) Boot your mobile in fastmode using Power ON with Volume down key for 5 sec (Lenovo log with left hand side sayinh fastboot mode)
2) Connect the mobile to PC using USB & Go to adb tool folder. Open command prompt in this folder & Execute the follow step by step execution
fastboot oem reboot-recovery
3)Wait for mobile to boot in to recovery mode with TWRP
Now need to flash custom-rom followed by gapps installion.
I) You can use pendrive with otg to flash custom-rom followed by gapps
OR
II)You can use phone storage/SD card to flash the custom-rom followed by gapps
OR
III)adb sideload command as fallow
a)In TWRP recovery on mobile, goto Adavanced->ADB Sideload & Swipe to start the sideload
Now on PC execute . Specify custom rom path inside ""
adb sideload "C:\adb\images\MyCustomROM.zip"
Have a patience to complete the operation.
Click back for Adavanced Menu again.
b) Select ADB Sideload & Swipe to start the sideload
Now on PC execute . Specify Gapp path inside ""
adb sideload "C:\adb\images\open_gapps-arm-7.1-pico-20180611.zip"
c)Have a patience to complete the operation.
Once complete go to TWRP Screen.
d)Now go back TWRP main menu & select wipe->format Data.
Go to Reboot->system.
How to install TWRP if no OS there
1) Boot your mobile in fastmode using Power ON with Volume down key for 5 sec (Lenovo log with left hand side sayinh fastboot mode)
2) Connect the mobile to PC using USB & Go to adb tool folder. Open command prompt in this folder & Execute the follow step by step execution
a) To check the device is connected to PC or not
fastboot oem device-info
b) To flash the recovery. Give twrp path inside the ""
fastboot flash recovery "C:\adb\images\twrp.img"
c) To boot into recovery mode
fastboot oem reboot-recovery

TWRP Install Problem

After unlock bootloader
I tried to install TWRP and the cmd said okay and finish
but when I boot into recovery mode. it still be a stock recovery screen and a message displays at bottom left on the screen
"E:couldn't load bitmap fill_ball (error-7)
Warning: No file_contexts
Supported API :3"
So, I thought 'some internal file might be damage' then I install stock rom (update to Android 9 from system notification because my phone still Android 8.1 when I install TWRP ) but after update complete the message still show
question: what should I do to successfully install TWRP?

I can fix this!!
