assuming you have enabled OEM unlocking in developer options, try
fastboot flashing unlock

also given that command and also
fastboot flashing unlock

so what was the error message then

seems unlocking is disabled in aboot therefore no common unlock method will work. at least there is a working firehose programmer for that device, so you can dump boot.img off the eMMC and try to modify with AIK and Magisk (AVBv2 signing required)

Need help rooting Alcatel 1c (5003D)

Hi,
I've now spent quite a few frustrating hours trying to root my Alcatel 1c (model 5003D, running Android 8.1 Go) and nothing seems to work. A short overview of some of the rabbit holes I've gone down:
Root tools
Started with the obvious: root tools. In short, none that I ran work. There's a couple I haven't tried because the instructions were mostly in Russian and some googling turned up quite a few mentions of them containing malware, but other than that I've pretty much tried all the major ones.
Flashing images via fastboot
Naturally, the next place I turned was the awesome resource that is this forum. This thread gave me plenty of hope, but I was soon flummoxed by my device's fastboot mode for which a bunch of the normal features are either broken or are simply not implemented. Some examples of things that should work (and indeed work on other Alcatel phones, notably, it seems, ones that are not based on Spreadtrum) but didn't:
Code:
~/D/platform-tools > ./fastboot oem unlock
FAILED (remote: 'unknown cmd.')
fastboot: error: Command failed
Code:
~/D/platform-tools > ./fastboot oem unlock-go
FAILED (remote: 'unknown cmd.')
fastboot: error: Command failed
Code:
~/D/platform-tools > ./fastboot oem unlock-go --wipe
FAILED (remote: 'unknown cmd.')
fastboot: error: Command failed
Code:
~/D/platform-tools > ./fastboot flashing unlock
FAILED (remote: 'Not implemet.')
fastboot: error: Command failed
(note the spelling error in the error message...)
Code:
~/D/platform-tools > ./fastboot flash recovery ../recovery.img
Sending 'recovery' (28266 KB) OKAY [ 1.582s]
Writing 'recovery' FAILED (remote: 'Flashing Lock Flag is locked. Please unlock it first!')
fastboot: error: Command failed
That last one was particularly intriguing, as it suggests there is a Flashing Lock Flag that can be unlocked. I tried all of the fastboot commands that seemed relevant but couldn't find any way of setting that flag or even figuring out if it actually exists. I even rand the boot.img through strings to see if I could find something interesting, but didn't turn up anything.
Just to be clear, before doing all this I set the phone to Developer Mode and checked the "OEM unlocking" feature.
Flashing tools
I tried various tools with which it's possible to flash phones. A lot of them use fastboot under the covers which doesn't work (see above). Some of them don't but didn't work on my phone all the same, for various reasons:
SPD flash tool - After yet more Googling I stumbled upon the SPD flash tool,built specifically to flash Spreadtrum-based devices. I downloaded the latest version, installed all of the necessary USB drivers and tried to flash the phone with the stock ROM. No dice. The tool fails to connect to the device via the USB2Serial thing that it uses to communicate. No idea what's going on or why it won't work, and haven't yet mustered the courage to dive into the source code. Of course, if I do get it to work, then I have to figure out how to actually root the device using this tool. I'm guessing it will involve unpacking the ROM (a PAC file), modifying the recovery.img to a TWRP (or similar), repacking it and flashing the result. I've only managed the unpacking so far, no clue as to the other 2 steps. BTW, the SPD flash tool site als has a "factory" and a "research" tool, besides the "upgrade" tool that I tried. Unless I'm missing something, all three seem to be exactly the same (save for the color scheme).
Alcatel Mobile Upgrade S - Installs just fine and then allows you to choose your phone out of a dropdown... that doesn't include my model.
Sugar MTK/QCT - Installed it and the necessary drivers but it can't find my phone, no matter what I try. Also, I keep reading that it needs login credentials (wut?)
Conclusion: argh!
So, nothing so far. Since it's a Spreadtrum phone it has an engineering mode that can be explored with an APK I found in this thread. Nothing in the settings it reveals appears to be of any help though. I also contacted the makers of the AIO Alcatel toolkit to see if they had any ideas, but after I explained the situation one of them concluded "Hmmm. New one on me". Needless to say I also tried searching this forum for more tips, but googling 'site:forum.xda-developers.com "5003D"' returns no hits.
For now, I'm forced to conclude that there is a lot of really awesome tooling out there created by some very talented people, but none of it works on my phone. As of yet the 5003D appears pretty unrootable. If anyone has any tips to help me along or point me in the right direction, I would be very appreciative.

Then type the command to show the device
fastboot -i 0x1bbb devices
Execute the next command which will show device info including bootloader status (e.g. locked).
fastboot -i 0x1bbb oem device-info
This command is to unlock the bootloader on Alcatel device
fastboot -i 0x1bbb oem unlock
Repeat Step and you should see “Device unlocked: true”
To reboot normally type:
fastboot -i 0x1bbb reboot
Done
This command is to unlock the bootloader on Alcatel device
fastboot -i 0x1bbb oem unlock

Rooting your phone's Android does NOT require you fiddle around with its boot-loader. Forget trying to make use of Fastboot.
So how would I go about this without using fastboot?

1. Open Windows command prompt and input the following comand
Code:
adb devices
2. Start the ADB sideload in your phone's recovery
3. Then input the following command in the Windows command prompt
Code:
adb sideload <filename.Zip>
where <filename.zip> must of course be the real full filepathname of ZIP to get flashed

TCL 20b Subforum

Hello there,
A newbie here, trying to unlock a TCL 20B (6159K) phone.
Android 11, November 2021 security patch (MTK Easy Su doesn't work with that, reportedly some vulnerability was patched), fastboot accessible but acting weird.
1. Got fastboot from here.
For some reason it doesn't understand the -i option, but connects with the only phone I'm trying to unlock attached anyway.
VID is 0x0e8d, btw.
2. Got adb from don't remember where about a year ago (for my previous Lenovo phone)
3. Unlocked the Developer Options
4. Checked "Allow bootloader unlock" and "Enable USB debugging" options there (not sure how those are named exactly in English, but I 100% guarantee, I've checked the right ones)
5. Sent phone into fastboot with
Code:
adb boot bootloader
6. Checked the unlockability with
Bash:
fastboot flashing get_unlock_ability
(bootloader) unlock_ability = 16777216
OKAY [ 0.005s]
Finished. Total time: 0.006s
7. Tried to unlock the thing, but
Code:
fastboot flashing unlock
FAILED (remote: 'not allowed in locked state')
fastboot: error: Command failed
and
Code:
fastboot flashing unlock_critical
FAILED (remote: 'not allowed in locked state')
fastboot: error: Command failed
8. Searching here, on XDA forums revealed there's no TCL 20B sub-form.
9. While there are tons of topics on not allowed in locked state, none of those helps.
fastboot oem unlock is seemingly an old way to do things (TCL 20B is a rather new device released WAY past 2015)
TCL is an Alcatel device, not a Xiaomi or some ZUK one, to require an account (haven't found anthing on "alcatel account")
trying to load some recovery from PC that might work failed as well (for the same reason)
Code:
[/LIST]
./fastboot boot twrp-3.6.1.img
Sending 'boot.img' (8932 KB) OKAY [ 0.212s]
Booting FAILED (remote: 'not allowed in locked state')
fastboot: error: Command failed
I've read some TCL 10 phones don't even have a fastboot, but TCL 20B clearly does.
Any Ideas how to unlock the bootloader?
P.S. Maybe a new sub forum for 20B? This got placed into the "TCL 20 5G" one, which doesn't seem right.
EDIT:
Ok, have found how to proceed on my own.
Even rooted the thing.
Go here https://github.com/bkerler/mtkclient, grab the ISO, backup, install patched magisk, patch the boot_a, flash patched boot_a and empty vbmeta_a, erase metadata, userdata and md_udc. Reboot, reinstall pathched magisk.
Don't lock the bootloader to avoid red state.
Huge kudos to mtkclient devs
Hello, i been trying to root my tcl 20b (6159a) but i cant figure how, i follow the instructions of mtkclient. Install it in windows, python, mtk repository, all the process, but when i try to replace boot_a.img it doesnt work from the cmd command, but in the python mtk_gui i can replace boot_a.bin and erase vbmeta_a.bin when i do it from there the cellphone keep in bootloop, i can fix the bootloop but cant root it. If u read this, can you plz be more specific with the steps, and made a little tutorial, its not necessary images or video just some more in deep info how you achieve root, thx

Question How to lock the bootloader

I bought the Asus ZenFone 8 Flip with the bootloader unlocked, it is not running a custom ROM. How do I lock the bootloader? Thank you
Try this with fastboot:
fastboot oem lock
However, this won't restore your warranty and you won't receive updates, since surely who has unlocked your device has used the official bootloader unlock tool which registers your serial number

You won't get OTA updates, but you can still update manually downloading the zip from Asus website.
Unfortunately that's the price if you unlock the device (not only for Asus, a lot of other manufacturers (i.e. Sony) do this too)

interesting... So I don't know how to lock the bootloader precisely. So I download the latest firmware from the Asus website, plug the phone into the computer run fastboot then what? Am I missing something?

No, just follow these steps:
Make a backup of your phone!! Unlocking/Locking the bootloader erases all your data partition (so all your stuff will be gone!)
Install ADB on your PC if you don't have it (check how to install it: https://www.xda-developers.com/install-adb-windows-macos-linux/).
Plug in your device via USB with Debug USB setting enabled (in Developer Settings)
Open a terminal prompt on your PC
In the terminal run adb devices. If you see your device I the list then you're fine. Otherwise, you have mistaken something in the previous steps.
Run adb reboot fastboot (or adb reboot bootloader if it doesn't work) to reboot into fastboot mode
Run fastboot oem lock to lock the bootloader
Run fastboot reboot to reboot the system
Your device is now locked!

I'm not responsible of any data loss, damages and/or bricks you make to your device(s) by following this guide!

To update the system when a new version is out, since you won't receive OTAs:
Go to Zenfone 8 Flip support page: https://www.asus.com/Mobile/Phones/ZenFone/Zenfone-8-Flip/HelpDesk_Download/
Choose Android as OS and scroll down to "Firmware"
Download the latest zip
Put it in the internal storage (in the root directory, not inside another folder!)
Two paths:
If you put the zip from PC via USB simply unplug the USB cable
If you downloaded the zip and put it manually via file manager from the phone reboot the system
A notification should pop out, notifying you there is a firmware package to install!
Just follow the notification message and you'll be done!

Oh that's an issue I have all the times with Asus devices. There's a simple one-time fix though: just install the official Asus ADB drivers.
Download them from this page (I know it's the smaller Zenfone 8 page, but they work with every Asus device): https://www.asus.com/it/Mobile/Phones/ZenFone/Zenfone-8/HelpDesk_Download/
Choose your windows version (for 10 and 11 choose 8.1)
Download the USB driver
Extract the archive somewhere in your PC
Open Device manager in your PC (search it in start menu) while the phone is connected via USB and in fastboot mode
You'll notice an unknown device with a yellow/orange warning icon at the top of the devices list. Right click on it and choose Update drivers.
Choose "Search driver in the PC" (the second option (don't choose the first one since it searches the driver automatically on Windows update))
Choose the folder you extracted
Click "Next"
Drivers should be installed and fastboot should recognize your device (to test run the command: fastboot devices)
Sorry for the late reply, but I didn't get any notification from XDA
there were two options for drivers android adb and android composite adb drivers I selected the composite one but it doesn't seem like it was installed
Kiribro02 said:
When I try to update the drivers it says that windows was unable to install your and then it says the device.

Do you installed the drivers when the phone is in fastboot mode?
Also, I've noticed some steps are not clear (and one is doubled), I'll clean it

Hi,
I've bought a second hand zenfone 8 flip. After Hard Reset I have to enter the old PIN to continue. The problem is the seller doesn't have the PIN and is not willing to take the phone back. ASUS is not willing to help because I bought it second hand.
I already flashed with raw firmware, but this is still coming up.
Any ideas? Should I start a new thread?

@maicol07 there's no OEM unlock in my developer options, only the USB debugging (which is already on)
besides this oem method, is there another way to lock it? perhaps through the zenfone flash tool (I have it installed and it detects my phone, but never used it)

Nokia C100

So I got a Lil c100 a couple days ago. It has a screen lock and the recovery mode don't work. Everyone says get it into fastbook amd use that to get to recovery. But the problem is after I get into fastboot the device isn't found. I've installed every USB driver known to man about fastboot or Nokia in general. And yet it still not popping up. Can sb help me?

The error I’m getting is “fastboot: usage: unknown device target recovery”
I am experiencing the EXACT same thing. No matter what box program Im using , nothing works! crazy. Please help. Id be happy with a factory reset. Atleast then I could get past the FRP.
Wow, I have not encountered that error yet.
I could only guess that it might be a problem of recovery.
How did you install your current recovery if not from fastboot?

Hey any update on this? I can say I've come across the same issue where their seems to either be no recovery or a corrupt one.
One thing I want to point out is (at least with the TracFone) that when I put the device in fastboot, and have wondershare tune go running, it displays the device as a Sony Xperia. The program still isn't able to connect to the device for me to attempt a reboot into recovery. It also reads the device as two other devices.
I'm hoping someone has encountered these findings and may also have a dump of the stock rom.if so I may be able to begin rooting for at least fix the recovery issue.

you need to use a special mtk boot mode script you can download here #101

Hey thanks for the response.
So far I've been able to get the device to read in fastboot but I'm still unable to unlock the bootloader since as your saying it's definitely..."gimped" haha. I'll checkout the script and do some tests to see what I get.

if you're curious you can always reach out to this guy, he's able to get prototype boot loaders and stuff: https://twitter.com/Hikari_Calyx
might even know how to get test points to force it into brom for mtkclient

Cat s31 oem (bootloader) unlock

first of i apologise if i have bad english
ok so i had this device for some time and decited to root it (my first time rooting a phone). And i need to unlock bootloader to flash stuff and i have all necessary things on my pc (platform tools,drivers,) everything seems to be working but as soon as i get into bootloader the only command that works is "fastboot devices" Any other commands dont work. I tried everything online and this is my only other thing left to do. I've been researching for 2 days at this point and i am almost certain that the commands are disabled by the company itself (like huawei) did anybody else ever root/unlock bootloader for this device because i didnt find any actual root guide for the particular device (besides from the auto generated ones like https://rootguia.com/how-to-flash-caterpillar-cat-s31/ https://mobilewithdrivers.com/unlock-bootloader/cat-s31-16gb-2gb-ram )
The exact error is:
FAILED (remote: 'unknown command')
fastboot: error: Command failed
(and this error is for every single command that uses fastboot besides from fastboot devices. Adb works just fine)
I tried:
reinstalling drivers
installing drivers that are "prepared" for the cat s31
changing cable
changing port to usb 2.0
reinstalling platform tools (from official google site)
checking device manager for the device (it shows up as android bootloader interface)
trying alternative oem unlock commands (fastboot oem unlock, fastboot flashing unlock and 2 other commands that i cant remember rn)
having oem unlocking and usb debugging enabled from the developer options
in my opinion the only explanation is the commands being disabled by default and even if it was it wouldnt be known if it was since most people dont root or purchase this device
please help me out here
fastboot flashing unlock
FAILED (remote: 'unknown command')
fastboot: error: Command failed
or
command finished but unlocking not allowed?
you can try to dump ROM, maybe it's possible to unlock bootloader on devinfo partition

sorry i forgot to mention im running android 8.1 oreo on this device and devinfo partition method will not work according to what i read
Never mind. anyway, if you dump phone in edl mode (or download stock ROM somewhere else) you can search aboot for device specific fastboot oem commands
How to Discover Hidden Fastboot Commands
There are many hidden fastboot commands on your device. In order to find them, we will need to dump the bootloader and examine the contents!

what do you mean by dump phone into edl mode do i download one of these https://ministryofsolutions.com/2022/01/cat-s31-edl-firmware-android-8-1-official-rom.html and install it from recovery mode and try to get it in edl mode and will it not work if i dont dump
just extract that ROM you found

find the file aboot.mbn (or similar) and analyze for fastboot commands

so i downloaded the file and these are the things in the firmware file (attachement)
i cant find a file that looks or resambles aboot.mbn
it's emmc_appsboot.mbn so download strings for windows (see link post #4) and try to find fastboot commands, maybe you are lucky and find the proper command to unlock bootloader.
edit: not sure about Windows 10/11 comes with strings binary (powershell?)

sooo turns out win11 strings commands are kinda different or broken (probably not im just dumb) i just used notepad with ctrl+f and couldnt find anything besides the text that says are you sure you want to unlock bootloader but that is probably not related since i didnt find any commands or anything. So im actually going to attach the emmc_appsboot.mbn i know it looks sketchy you dont have to download it its totally understandable but if you do please do give it a check and respond. I want to get this done one way or another its 1 am i want to sleep ;(
could it be true that they made a truly un unlockable unrootable device
I had a look but there are no fastboot commands in it. However "oem unlock" is mentioned, so the usual fastboot oem unlock should work.
maybe there is more in secondary bootloader sbl1.mbn

edit: the only place oem unlock is mentioned is a text that says oem unlock not allowed which might be default text by android or whatever but cat devs somehow messed it up somehow??

just saw the edit i will check now
nope nothing related no oem unlock no fastboot no flashing no flash nothing is mentioned ill attach it if you want to look
oem unlock not allowed is standard text if one forgot to enable oem unlocking in developer options in android settings.
maybe flash this ROM maybe it is unlockable?

from recovery using the flash firmware with adb option??
edit: i meant apply update from adb
edit2: what if i hard reset from recovery would that reset the firmware?
edl firmware cannot flashed from recovery. power off phone, press both volume keys and plug in usb-cable. check VID/PID from windows device manager. if you see device ID (05c6:9008) the phone is in EDL mode. you can now use EDL tool (post #2) and backup current ROM. then you can flash other ROM.
