Hello all,
I have Zenfone 2 on which I intended to use a custom ROM.
So the first thing was to unlock the bootloader.
On previous occasion, on my Nexus, I had used the - fastboot oem unlock - command and it had worked. So with that in mind, I booted into the bootloader and tried the command, but it failed - saying oem command unrecognized.
Then I searched online and apparently, to unlock the bootloader, Asus has launched an app! But to be able to install the app, I need to get a normal boot happening, which is not happening now.
In between all this, I tried the commands - fastboot flash recovery <recovery.img>, fastboot flash boot <boot.img> too. But none of these were successful, and each of them returned a 'Permission denied' message, probably coz the bootloader was locked.
Now the situation is that -
- Bootloader is locked.
- Phone is stuck in bootloader
- There is no recovery installed. In fact, from the bootloader, when I try to boot into 'Recovery Mode', it goes there for a second and returns back to the bootloader. Doesn't show the normal android image with a 'X' on top.
- There is no root access.
Now I think the first step is to get root access, and for this I want to try the method with installing CWM recovery and SuperSu.
But for this, I need to be able to push the SuperSu.zip to the phone, which I am not able to.
Can somebody please help!
r the drivers for fastboot & adb update to date?
Android version?
If the phone is stuck in bootloader, you can use Asus Flash Tool to flash .raw files and unbrick the phone.
Raw files: https://yadi.sk/d/FijRoAVJtvRiG
AFT: https://yadi.sk/d/NQCiY--IsQjBr (I use AsusFlashToolInstaller1.0.0.14.exe).
you can use Asus Flash Tool to flash .raw files and unbrick the phone.

I wanna get back to the official rom, after trying android P (without make it work).
(the rom is from http://en.miui.com/download-354.html)
But I run the wrong script and take the flash_all_lock.img
And my device is stuck on android 8.1 bootloop (It boot, but i get an animated line loop ...)
Any ideas or tricks before i get it back to warranty ?

Unlock bootloader and flash again. You can find a guide to unlock bootloader at the beginning of this guide.

Have you tried to switch the active slot?
Try if it boots using
fastboot set_active a
or
fastboot set_active b
If not working, can you enter recovery (power on with Volume up button pressed)?
If you can enter recovery, hold down the power button for 3-5 seconds and then press and release the Volume up button, to make commands appear. Then your only hope is to install the OTA update zip from there (copy the OTA in a microSD card, there is a thread where you can find the link to the OTA zip).
In my opinion, "OEM unlocking" in developer options MUST be always keep active, because incidents like this could happen, and because even without modding, an OTA could go wrong resulting in your same situation.
I was in your same situation (OEM unlocking disabled and then I locked bootloader with a custom ROM installed) with a Nexus 5X.
I don't remember well how I fixed it, but I remember entering in Qualcomm download mode (should be the same EDL mode) and loading a file found after many hours of research in strange forums and sites.

In fact, both work, but my phone still stucked at the bootloader (infinite line animation in both cases).

Yes I can enter recovery and I have already tried this, but I always end up with the error:
Code:
E: Unknow volume for path [/sideload/package.zip]
Verifying update package...
Update package verification took 17.3 s (result 0)

Yes of course !
But I revert to stock rom with Mi Flash and I click on Flash all and lock, since the telephone should have been "brand new" it should not have any problems but ...
I have to enter EDL mode, but don't know how to do it since modified fastboot executables does not activate it it just reboot the phone...
Deep flash cable may help but not shure if it works, or I may have to disassemble the device to find EDL pins...
after unlock bootloader type fastboot flashing unlock_critical and flash with miflash tool

try this http://www.xiaomitool.com/ not sure if it works on our phone but maybe can unlock the bootloader so you can use miflash
Have you sideloaded the zip? I think it's better to copy the OTA zip to microSD than ADB sideload.

There should be only two methods for entering EDL:
1- request authorization in en.miui.com forum. Sometimes the admins accept requests to give an account one EDL flash permission (but I don't know if it works with AndroidOne devices).
2- finding the test point in the phone's motherboard.

How to unbrick?
Hey guys. I bricked my Mi2 Lite as well. Is there any step by step way to unbrick?
had the same problem, was stuck in the bootloop even after I flashed img with MiFlash! NOTE: MY BOOTLOADER WAS UNLOCKED!!! (LUCKLY I DID NOT TRIED FLASH ALL AND UNLOCK!)
headed to this thread
Code:
fastboot flashing unlock
fastboot flashing unlock_critical
did not work, I get error saying FAILED
but after i used
Code:
fastboot oem edl
I went to MiFlash and used "Clean all" option (again note DON'T use "Clean all and lock"!!!). It took around 5 minutes to flash and my notif. light blinked whole the time. After it say "Success" I was able to normaly boot the phone again
Find "Mi A2 Lite toolkit V 1.0.4.2" and use it to flash stock 8.1, it will do all the magic with a few clicks, just don't interrupt it until your phone restarts and you get the "Welcome" screen. After you can do the upgrade to Pie via OTA.
Hi, where i can find MI A2 Lite Tool Kit? i open my device and i can put in EDL mode., my computer detect my pone in EDL mode, but i can not know do.
I like bypass FRP, can anybody help me
Thanks.

Hi all,
I also had same problem and I just resolve it.
My phone was in bootloop mode after stock rom flashing...
You don't need apply "fastboot oem edl" !
Just be sure your device is unlocked.
Download first stock rom (V9.6.4.0.ODLMIFF Firmware for Mi A2 Lite). If you flash last ROM, it don't work.
Flash it with XiaoMiFlash tool (don't forget to enable "Clean All") in bottom of the tool.
After reboot, you can apply OTA updates.
Enjoy !
Thanks for taking the time to read this post

Any help pleasee. i am loosing my mind here. i just want any of these phones to be rooted.
I've been trying to unlock a Blu G5 - I've gotten as far as patching the disk image and all that is left to do is just flash the image onto the phone.
The issue is whenever I try to flash something onto the phone I get the following error :
Code:
FAILED (remote: Flashing Lock Flag is locked. Please unlock it first!)
.
When I go to unlock through Flashing unlock I get the error in the title - OEM unlock gives me cmd not found.
I have USB debugging and OEM unlocking both enabled inside the app settings. I'm not sure if its pertinent but on Magisk I see "Ramdisk : No". I've also been unable to get into recovery mode despite trying every combination possible except for once on accident (which I haven't been able to replicate).
Any help would be appreciated, Thanks!

having the same problem right now. did you get a fix?
Ive had my LG G7 for about a year now. I managed to unlock the bootloader without any problems and used magisk ok.
I just came to upgrade the firmware without any problems. I enabled dev and usb debug but the 'Enable oem unlock' button is greyed out and displays "bootloader already unlocked" ok so not a problem - that is until I come to access the bootloader again.
Here is the message:
Welcome to Fastboot mode: Please check "Enable OEM unlock" in developer options
adb commands no longer work at this point as connection is lost. Only choice is manually reboot or switch off.
WTF now what. Im unable to root or restore the bootloader. So even though its unlocked and displays the bootloader unlocked message when booting - Fastboot does not see it and it still wants me to 'Enable oem unlock' but its greyed out.
Any suggestions please anyone
You can use QFIL to restore laf_a & laf_b. Then flash full rom (Refurbish) in Download mode.
ps: the reason is you do not flash full rom after unlock bootloader in order to tell to the machine that you are in the illegal mode kakaka.
Thanks for your reply nttuan. I just about gave up hope. Im totally paranoid without root. No decent firewall, cant freeze garbage etc.
Being relatively unsure, would you mind going over the QFIL method with me.
Thanks

Never used QFIL before. Where do I get the firehose elf file from. I noticed a couple of elf files in the extracted folder, is it one of these.
Do I have to create any xml files and do I have to rename any of the kdz extracted files?
Some posts are a bit old and for other models.
Instead of flash the boot_a from magisk_patched image, you can use command
fastboot boot magisk_patched.img
and use the LGUP to reflash the firmware.
If you look at the photo above I LOSE ALL ADB commands after adb reboot bootloader.
fastboot boot magisk_patched.img or any other command just displays "Waiting For any Device" in CMD window.
This is my problem because the bootloader is already unlocked and oem greyed out - it is asking me to "Enable OEM Unlock"
I am wanting to either root the phone or restore bootloader to locked. Sorry for any confusion
type fastboot devices and show me the result.
maybe you do not have correct fastboot driver
It did say waiting for any device but now its gone from bad to worse. I followed this guide Here and now all I get is fastboot screen, see photo. If I now try fastboot devices then fastboot flash boot_a magisk_patched.img it shows error which does not look good actually , photo 2. Cant get download mode. If I try to get it by holding volume button and inserting usb lead I get this nasty screen, photo 3. I think that some of the partitions may have been overwitten. . Stupid move on my part.
Forgot to mention - EDL is still accessable
Ive managed to sort the above problem
QFIL flashed only the following 6 files :
abl_a and abl_b
laf_a and laf_b
boot_a and boot_b
Phone rebooted perfectly after this.
Thanks for your advice
