Hi folks,
I just received my Essential Phone, purchased through amazon. As you recall, the Essential Phone was rumored to have an unlocked bootloader. This was confirmed by @essential confirming that it will, in a tweet.
However, this is not what I'm experiencing with the phone.
After powering it up and playing around a bit, I enabled USB debugging and linked it to my computer, where I have the latest (as of today) android platform tools installed. I rebooted to fastboot and tried to issue "fastboot oem unlock", as I did with my previous phone, a nexus 6p. However, it seems "oem" is no longer a valid subcommand of fastboot; it has been renamed to "flashing unlock", along with some other new-to-me commands:
Code:
$ fastboot --help
usage: fastboot [ <option> ] <command>
commands:
.....
flashing lock Locks the device. Prevents flashing.
flashing unlock Unlocks the device. Allows flashing
any partition except
bootloader-related partitions.
flashing lock_critical Prevents flashing bootloader-related
partitions.
flashing unlock_critical Enables flashing bootloader-related
partitions.
flashing get_unlock_ability Queries bootloader to see if the
device is unlocked.
flashing get_unlock_bootloader_nonce Queries the bootloader to get the
unlock nonce.
flashing unlock_bootloader <request> Issue unlock bootloader using request.
flashing lock_bootloader Locks the bootloader to prevent
bootloader version rollback.
The "flashing unlock" command looks interesting. Let's try that:
Code:
$ fastboot flashing unlock
...
FAILED (remote: Flashing Unlock is not allowed
)
finished. total time: 0.003s
Hmmm... I don't like the look of that. Well, let's see what "get_unlock_ability" says:
Code:
$ fastboot flashing get_unlock_ability
...
(bootloader) get_unlock_ability: 0
OKAY [ 0.000s]
finished. total time: 0.000s
Ok, that looks bad too. Let's try those other new commands and see if we can get anywhere...
Code:
$ fastboot flashing unlock_critical
...
FAILED (remote: Flashing Unlock is not allowed
)
finished. total time: 0.002s
Nope.
Code:
$ fastboot flashing get_unlock_bootloader_nonce
...
FAILED (remote: unknown command)
finished. total time: 0.000s
Double nope.
Well that's not encouraging. I don't claim to be any sort of expert in regards to unlocking phones, but I can't find any other methods using these tools, and Essential's docs aren't any help. I've contact their phone support but haven't heard back after about an hour. (They use some ridiculous system where you schedule a callback... Not happy.)
So, I'm feeling pretty upset. Let's be clear here:
Essential said this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
But shipped a product with this:
Code:
$ fastboot flashing get_unlock_ability
...
(bootloader) get_unlock_ability: 0
OKAY [ 0.000s]
finished. total time: 0.000s
Did you turn on the allow unlocking toggle in developer options?

1) Check the box next to OEM Unlockable.
2) Then reboot your phone to fastboot
3) In a command prompt within the adb folder: type -> fastboot flashing unlock
4) Use the volume button to click yes when prompted.

I've tried all of these steps and once I get to the fastboot flashing unlock step my cmd prompt just hangs at waiting for device and I never get the option for "Yes." Instead I have Start, Recovery, Power off, etc.
What am I doing wrong?

First in fastboot type "fastboot devices" if a string of numbers answers it is ok otherwise you need fastboot driver ....have you cheked?
Hi guys, I have an issue with unlocking the bootloader. fastboot devices returns the device ID, but flashing unlock gives me failed, unknown command error. I cannot get it working. Any ideas?
/edit: changing PC's helped

If you've already waited for some time to pass, i would let it go dead, then plugin and allow it to power up on its own. I've only had limited success with this though. Other options are goto into recovery mode and factory reset.

Yeah, I had such instances too in the past. But no luck this time...
My OEM locking is not switched on and I'm unable to sideload the OTA or Rest the phone to factory.

Introduction
As we know, the official way to unlock the bootloader of Zuk Z1 is through fastboot.
For a untouched device, the status of the bootloader should be:
Code:
fastboot -i 0x2b4c oem device-info
...
(bootloader) Device tampered: [COLOR="Red"]false[/COLOR]
(bootloader) Device unlocked: [COLOR="Red"]false[/COLOR]
(bootloader) Charger screen enabled: false
(bootloader) Display panel:
To unlock the bootloader, you need to enable 'OEM unlocking' under Developer options first, then via bootloader/fastboot interface:
Code:
fastboot -i 0x2b4c oem unlock-go
It'll eventually erase the userdata.
Then the status of the bootloader should be:
Code:
fastboot -i 0x2b4c oem device-info
...
(bootloader) Device tampered: [COLOR="Red"]false[/COLOR]
(bootloader) Device unlocked: [COLOR="Red"]true[/COLOR]
(bootloader) Charger screen enabled: false
(bootloader) Display panel:
Inspired by the findings on similar devices, we can actually unlock the bootloader of Zuk Z1 without using fastboot, while keeping the userdata intact.
How-to
Warning!
It is dangerous! This whole thing is basically one giant hack - which is not intended to be done by normal users. It is messing with the bootloader partition, so it is possible that something goes wrong and you will have a nice & costly brick in your pocket. Be prepared to revive the device from a hard-brick.
1.
Enable 'OEM unlocking' under Developer options. You may need to tap the Build number 7 times under About phone to get the Developer options under Settings.
2.
We need root access (kinda expected!). To root the device without unlocking bootloader, use KingRoot. Use the Android version.
Now there is a catch! KingRoot can root the device, cause the latest build of Cyanogen OS (cm-12.1-YOG4PAS3OH-ham ATM) contains such vulnerabilities which can be exploited by the root exploits used by KingRoot. But we can't ensure about future.
3.
After being rooted, use adb shell or any terminal emulator to dump the 'aboot' i.e bootloader partition in internal sdcard:
Code:
su
dd if=/dev/block/bootdevice/by-name/aboot of=/sdcard/aboot.img
4.
Now we need to modify the dumped image using hex-editor. For Zuk Z1:
Code:
Unlock Bit Position - 0x001FFE10 Hex
Tamper Bit Position - 0x001FFE14 Hex
'00' means false, '01' means true. So to set the bootloader as unlocked, we just need to change the following:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Save the modified image as 'abootmod.img' inside your sdcard.
5.
Now its time to flash back the modded bootloader. Execute the following from adb shell or any terminal emulator:
Code:
su
dd if=/sdcard/abootmod.img of=/dev/block/bootdevice/by-name/aboot
Do a reboot & voila! You have unlocked the bootloader! Don't just believe me - check the status of the bootloader to ensure.
Note
1. We can also reset the tamper bit using this procedure.
2. If you prefer GUI, then you can use this fantastic app by @wanam.
3. This is tested on an international Zuk Z1 running cm-12.1-YOG4PAS3OH-ham. Please test & post feedback to ensure compatibility.
4. I'm not providing pre-modified images as it increases the risk of bricking the devices having older/newer bootloaders - please do it yourself. The offsets should be unchanged in future, though.

Happy tinkering! :highfive: :good:
Reserved for future.
I tested now and working okay. Thaaaaaaaaaaaaaaaaanks
after using dd for writing the modified image it worked. seems to be a problem using the app Partitions Backup & Restore
old post
Doesn't worked for me.
fastboot -i 0x2b4c oem device-info still shows
Code:
...
(bootloader) Device tampered: false
(bootloader) Device unlocked: false
(bootloader) Charger screen enabled: false
(bootloader) Display panel:
OKAY [ 0.009s]

when I read the aboot-partition after writing the modified image my modification is gone, i used Partitions Backup & Restore App for reading and writing

Problems with fastboot
I was going to follow this guide but fastboot doesn't recognize my zuk. I tried to install all the drivers from sdk, and then i tried also to manually select them in the devices settings of windows but my pc says that there aren't any drivers in the folders. Ho can I solve it? I looked over and over the internet but this phone is apparently really rare so there are no working solutions for this. Can someone help me? :crying:
It works!
Zuk Z1 international, it worked perfectly! Just, I had to change the name of abootmod in about to substitute the original file, so " dd if=/sdcard/aboot.img of=/dev/block/bootdevice/by-name/aboot "

First, Unlock Bootloader
Install TWRP for Le X626
Download Magisk or SuperSU
Put Magisk or SuperSU in internal storage
Reboot to TWRP
Install from zip
Choose Magisk (Recommended) or SuperSU
Reboot

Can you please post something similar for rooting Le2 X526 model?
I would like to install Magisk instead of supersu as I have heard the former is better.
How to install TWRP for x626 according to the site the OP recommends.
From the same website, only without the adlinks. No guarantees from me, if you go through the instructions from the OP you will end up getting the same information.
– Make sure your Bootloader is Unlocked, if you don’t know how to Unlock the Bootloader then please go to here and Unlock the Bootloader of your Device.
– Download the Latest TWRP Recovery Image from https://dbr.ee/TKKC
– Reboot into Fastboot/Bootloader Mode.
– Run The Following Command from a Command Prompt in the Same Folder in which you downloaded the TWRP Recovery Image (Change twrp le x626.img to recovery.img):
fastboot flash recovery recovery.img
fastboot boot recovery.img

Unlock bootloader first
What rom do u use?
Hi Tickernel, and thank you for replying
I unlocked the bootloader as per Step 1 above and that completed successfully.
Moving on to Step 2 I got the recovery image following your links which led me to 'twrp le x626.img' (20MB), which I renamed to recovery.img.
There are two commands to execute in step 2, the first went ok, the second did not succeed

Hi Tickernel, so you're suggesting recovery in the sense of a total erasing of all apps and data? I'm willing to do it, but will make certain I have a backup first . Just want to confirm that this is what you think needs to be done.

Can you download the stock rom from your current version flashed and boot it? use command "fastboot boot boot.img". Boot.img is inside of the flashable stock rom zip. After this try toggling the oem unlock if not wait 7 days and try to update phone like regular ota in setings

I don't remember the steps to reproduce, but I remember being possible to take the very own boot.img currently flash on your phone. I think it was through adb commands, what if you try booting that one instead? That's what I did on mine, but it didn't help with toggling oem unlock, only entering the system
I accidentally locked mine and im in the same situation as everyone here, but i think the only solution is BlankFlashing or sideloading a signed OTA on it... Im trying everyday new possible methods of fixing it and if i get into some ill share here
hi guys, had exact same issue, spent hours trolling through the net, forums etc and this forum fixed it for me. I was about to throw the phone out.
something tells me that you have to have the boot image from the software you had installed before the crash/brick. Run the "fastboot boot boot.img"
i tried numerous boot.img's thinking I've spent too much time this device so as I turned my back on the phone I hear a 'Hello Moto' WTF...Up and running again. Good Luck

It would be the solution if the stock was corrupted, but i have locked mine on StyxOS, and there isn't any boot.img for it so stock boot.img gives a system corrupted error. But nice idea.

If your FTV is on FireOS 5 (505 and up), then forget about this sh*t. No unlock possible^^

I don't even know what version is out there. Given.
Wanted to add that fastboot works!!!
Maybe have the option of using test points to unlock?
Boot the FTV1 up (with disabled updates) and look in the settings for your fireOS version. Afaik the devices with 51.xxx (5 digits) can unlocked/rooted with software/adb.
FireOS 5 can´t bootloader unlocked, because bootloader checks fuses (5.0.5 and up). Last software rootable version is 5.0.5.
Aside from fireOS, if you build a low voltage emmc reader and solder wires to a few pins onto the board of the FTV, you can flash the emmc with twrp (for locked bootloader) and a prerooted rom from rbox.

I have it only boots to the logo and all to go to settings is not possible. I used a usb a-usb a cable to connect. So I have a prefix is defined in the device Manager as a fastboot device, and as adb is not. Will you be able to specify on the scheme to specify the contacts to which you want to connect and more detailed instructions for recovery?
Take a look at the gtv hackers, you can see the pin out of the adapter and the pins on the board. There is also a video.

If you get this adapter (seems sold out/ you need to build it on your own) you can read/write to all partitions on the emmc (with a pc running linux), flash a new recovery and so on.
But maybe you find a way to reset the FTV on this site?

Unfortunately, I don't have a low voltage eMMC adapter and don't know if I can find one. With UART you can unlock something? Uart is more available to me.
Don´t know, but don´t think so.

And how do you know why it doesn't switch to adb mode? Only fastboot works for me.

I would try a usb hub with a usb keyboard for reset if the reset via remote doesn´t work.
You can look in the bueller bootloader unlock threads here on xda (fire tv android development section), maybe the fastboot commands work for you.

Unfortunately, did not help a full reset Alt+i+Print screen, and adb is not available, only fastboot mode
Maybe try this:
fastboot erase data
fastboot erase cache

I tried, didn't help
PS D:\Amazon\platform-tools> fastboot devices
7090020141650DN4 fastboot
PS D:\Amazon\platform-tools> fastboot erase data
Erasing 'data' FAILED (remote: 'erasing not allowed for locked hw')

PS D:\Amazon\platform-tools> fastboot erase cache

Probably only this method will help, thank you very much for your help

I rebooted my G7 into fastboot to wipe the cache and I got stuck in it. I wasn't trying to load a new image or replace anything. When I try any option (Start, Restart Bootloader, Recovery mode, Factory Mode, etc) it fails with the following message in the log:
Code:
SSM: Android image rollback: 8.9
failed to validate boot image
ERROR: Failed to pass validation, backup to fastboot
Boot up failed
So, I downloaded adb/fastboot, got the drivers installed, and tried to download the latest image from https:__mirrors.lolinet.com/firmware/moto/river/official/RETEU/ and then tried to flash it.
When I try to replace boot.img:
Code:
C:\temp\moto-g7-firmware> fastboot flash boot boot.img
(bootloader) is-logical:boot_a: not found
Sending 'boot_a' (32768 KB) OKAY [ 0.990s]
Writing 'boot_a' (bootloader) Image boot failed validation
(bootloader) Preflash validation failed
FAILED (remote: '')
fastboot: error: Command failed
Well, that's probably because I didn't unlock my bootloader first? I didn't know I'd be doing this. Maybe there's a stock boot image that wouldn't cause me problems?
I tried to unlock my bootloader. I got my boot key but when I run:
Code:
C:\temp\moto-g7-firmware> fastboot oem unlock XXXXXXXXXXXXXXXXXXXXXX
(bootloader) Check 'Allow OEM Unlock' in Android Settings > Developer
(bootloader) Options
OKAY [ 0.021s]
Finished. Total time: 0.027s
Well, this sucks. I can't get into the phone to get to the Android Settings menu. I feel stuck. Does anybody have any ideas for me?

Thank you for the response. Unfortunately, LMSA doesn't work either . It says "This device isn't supported". I have no idea why not.

It seems that your USB debugging or OEM unlock toggle was un-ticked.
Do you have recovery available to format/reset device?
RSDLite doesn't work with your model?
Negative
Nope. I can't seem to get RSD Lite to work on Windows 10 to recognize my phone .

It is possible to flash the stock firmware while the bootloader is locked.
BUT: You can't only flash a single image, like the boot.img. You must execute the whole fastboot commands in the same order as you can find in the flashfile.xml inside the firmware.zip!!
I don't know why, but only single commands do not work.
BEFORE TRYING THIS: Make sure you flash the correct firmware! IT MUST be the same build as currently installed!! No RETAIL version or an older build version!
Well, that's weird
Huh. I tried LMSA tonight again just for fun and it worked fine this time. It found the image, downloaded it, and reflashed the phone to factory settings. Yay! I'm back in. I tried it many times before. I know my firmware updated on the phone a few days before this happened. I guess I just needed to wait for a bit. Thank you everybody.

For next time, how does one find the exact firmware needed? I could never figure that out.
