In Fastboot you cannot use adb commands but fastboot commands like:
Code:
fastboot devices
PAUSE
fastboot oem get-bootinfo
PAUSE
fastboot oem get-psid
PAUSE
fastboot oem get_hwnff_ver
PAUSE
fastboot oem hwdog certify begin
PAUSE
fastboot oem get-product-model
PAUSE
fastboot oem get-build-number
PAUSE
fastboot oem oeminforead-SYSTEM_VERSION
PAUSE
fastboot getvar vendorcountry
PAUSE
REM fastboot getvar rescue_enter_recovery
PAUSE
fastboot reboot
Some will probably not work with BL and FRP locked.
Your best bet is DC Phoenix, they can even unlock FRP without entering to System.
Discuss with them in advance, to know how many credits you must buy:

Thanks you for the answer...but, I don't understand why the phon don't start if it is unplugged from laptop or charger... If it is plug in pc it came only in bootloop or fastboot ..

Help guys.... I have bought 15 credits from DC unlocking but my P9 is not supported... I receive this message...

Ask them for help, you must first unlock FRP and for that you have to use HCU client:
http://hcu-client.com/
I never had to use HCU Client but people reported that they bought credits at DC and used for both HCU and FRP

Remake the phone warranty valid?

Hello guys,
Today when I tried to plug my headphones to listen to music, I noticed that the pone hardly recognises them. First I thought it was problem of the headphones but I tried to plug another and I almost must keep my finger pressing the cable where is plugged
So I think is problem of the headphone jack.
I have the bootloader unlocked so the warranty is void. I want to know if there is any method to lock it again to re valid the warranty

It´s hard because when you did the Bootloader Unlock procedure on Motorola website you gave to them your IMEI, so theorically if you send the phone to repair it will be rejected.
But I don´t. Here on Brazil a lot of users had general problems with Razr i, sended the phone with BL unlocked to the technical support and got a new one... So I don´t know, it deppends of how stuff works with Motorola in your country..
The command "fastboot oem lock", or something else, doesn´t work as other phones. So the bootloader is not lockable again via PC...

the command fastboot oem lock works, but two things:
The warranty is still void, because you require the code in the motorola website
The BL still show the "WARNING BOOTLOADER UNLOCKED" message
So if you want to lock the bootloader and don't want the "WARNING BOOTLOADER (...)" message follow this commands, This will delete your /data & /cache partition, and you need flash motorola signed files (firmware):
cd (firmware folder)
fastboot oem lock begin
fastboot flash boot boot_signed
fastboot flash bos bos_signed
fastboot flash cdrom cdrom_signed
fastboot flash gpt gpt_signed
fastboot flash motoboot motoboot
fastboot flash radio radio_signed
fastboot flash recovery recovery_signed
fastboot flash system system_signed
fastboot flash ulogo ulogo_signed
fastboot erase userdata
fastboot erase cache
fastboot oem lock
the first command will start the lock and wait for signed partitions, all the fastboot flash (...) commands will flash ALL the partitions signed's; the fastboot flash ulogo_logo will remove the "WARNING BOOTLOADER UNLOCKED" message; "fastboot erase (...)" will wipe the data partitions (required); Fastboot oem lock finalizes the bootloader lock process

I didn´t knew about this. Stills impossible to remove WARNING BOOTLOADER UNLOCKED message on unlocked devices using this "fastboot flash ulogo ulogo_signed" command?

No, Only fastboot flash ulogo logo_signed.
If you flash ulogo file still show warning bl unlocked, but if you do in fastboot "fastboot oem lock" they said: [FAIL] Already locked :silly: maybe motorola don't want the users relock the bootloader
Is our phone water resistant? Not submersions Because I had a problem when it was raining is that the problem? Does Motorola warranty covers this?

Would do the same procedure on the Motorola Razr HD? In firmware does not have the files "bos_signed, gpt_signed, motoboot and radio_signed" if any can help, I really need. Grateful.

Flashing bootloader unlock image gets stuck on waiting for device.

My device is plugged in with the stock cable and it is booted into bootloader via adb reload bootloader.
I've tried both fastboot -i 0x2b4c flash unlock unlock_bootloader.img and fastboot -i 0x2b4c flash unlock unlock_bootloader.img, both result in stuck on waiting.

I had a similar thing happen to me when I did my unlocking, fastboot doesn't recognise your phone, what happens if you send "fastboot -i 0x2b4c devices"?
Eventually I did figure it out but I can't remember the solution, but one thing that did work all the time was mauronofrio's multi-tool. https://forum.xda-developers.com/zu...ol-tool-one-driversunlocktwrpfactory-t3432782
Have a go, see if that works.

Hi, SachK2.
When I faced the same issue, installing the custom USB drivers that are usually attached to the bootloader unlock topic did the trick to me.
I tried the multi-tool but it gets stuck and crashes on the command window. I cant find the custom drivers download.

posting the links to another forum is disallowed here, though if I were in your shoes, I'd go on 4pda, search there zuk z2 pro topic and download the drivers there - wasn't able to find those drivers within xda yet
I'll also PM you the direct link so that you can check [the registration might be needed to be able to view and download the files]

fastboot getvar stuck

So I unlocked the bootloader for my Mi8, and now I'm trying to flash MIUI Global visa fastboot.
I'm running Linux and using USB2.0 with original cable and fastboot version 9.0.0_r30
When I type
Code:
fastboot devices
I can see that the phone is connected.
But when I try
Code:
fastboot getvar all
or any parameter for getvar , it just get stuck. By that I mean, the fastboot process hangs in there for a while and cannot be stopped with Crtl+C.
Also note that
Code:
fastboot oem device-info
works fine.
Another thing I noticed, when I repeate multiple instances of fastboot devices or oem device-info I get the 'press any key to shutdown'.
I'm not sure what is the problem. Any thoughts? I tried rebooting and changing USB ports but didn't help.

Unlock OEM via ADB

Hi, so my Xiaomi MI A2 is kinda not working and I think that wiping cache partition might help but I can't access the recovery so I wanted to install TWRP. The thing is I have the boatloader locked, I have the USB depuration activated but not the OEM, so how can I unlock boatload or unlock OEM via fastboot?
Thanks

It won't let me. It says:
my command: fastboot oem unlock System: FAILED (remote "flashing unlock is not allowed")
Fastboot: error: command failed.
Same with the critical. I also had an error trying another command, it said, not allowed in lock mode.
Actually, I'm trying other commands and it's the same error with all comands.

Question How to UNLOCK BOOTLOADER UNOFFICIALLY ?

Greetings!
As far as I know ASUS does not have a physical bootloader unlock counter like Samsung smartphones with their KNOX. This means that ASUS gets information about the unlocked bootloader via the internet when using their official unlock bootloader app. That is, ASUS gets the IMEI or S/N of the smartphone and puts it on their blacklist.
Is there any way to unlock the bootloader unofficially?
I really want to be able to get the bootloader back to its locked state and start getting and installing updates from my smartphone without using a PC as it was before the bootloader manipulation.
I tried these adb commands, but they don't work.
fastboot oem unlock
fastboot oem unlock confirm
fastboot oem asus-go
fastboot oem asus-go confirm
fastboot oem get_unlock_key
fastboot flashing unlock
fastboot oem asus-unlock working but i got error Verify unlock token fail.
