We have wrote many articles about Huawei Ascend Y300. Like this one on how to Root Ascend Y300 without unlocking the bootloader http://huaweinews.com/2013/07/root-huawei-ascend-y300/. And this one about an Android 4.3 custom ROM for Ascend Y300 http://huaweinews.com/2013/10/android-4-3-custom-rom-ascend-y300/. At the end of that post, we have promised you that we would write a guide to unlock the bootloader if you asked us in the comments. We received several requests for that and here’s our guide for you! This guide will explain how you can unlock the bootloader of Ascend Y300 easily to flash custom recovery and then possibly install custom ROM’s.
Unlocking the bootloader of Huawei phones has become easy with “DC-Unlocker” program. Its free and you don’t have to wait until Huawei sends you unlock codes.
Alert!
Unlocking bootloader might void your warranty! And Huaweinews.com isn’t responsible for any damages that might occur. Proceed at your own risk!Supported Y300 versions : Y300-0100 and Y300-0151
Download DC-Unlocker program from here - http://goo.gl/13AjnW
Install the drivers by using “driversetup.exe” from the downloaded files. Restart your comouter after installing Also install the DC-Unlocker program.
Turn off your Ascend Y300 and then Press Volume down+Volume up+Power button and hold it for few seconds until the sceen becomes purple. Then connect your Y300 to the PC and wait until it installs the drivers.
Open DC-Unlocker program and under “Select manufacturer” field, choose “Huawei Phones” and under “Select model” field choose “Auto Detect” and click the search button.
It will take few seconds and then DC-Unlocker will display the bootloader unlock code
Write down or copy paste this 16 digit unlock code somewhere so we can use it on next steps. Close the DC-Unlocker program. Now we have obtained the bootloader unlock code. Lets proceed in to next steps
Download ADB Toolkit from here - http://goo.gl/wfR141
Install the ADB Toolkit on the default location and open command prompt of your windows computer. Make sure your phone is still connected to the computer.
Type,
adb-toolkit\bin\files\fastboot devices
in the command prompt and hit enter. If it displays an result like the below screenshot, your Y300 is successfully connected to the computer.
Then type the below command to unlock the bootloader. Replace xxxx with the 16 digit unlock code that you obtained before
fastboot oem unlock xxxx
If you receive a result like above, your Ascend Y300 bootloader is successfully unlocked. You can verify it by using
fastboot oem get-bootinfo
Now you can flash a custom recovery on your Ascend Y300 in order to install custom ROMs. We will write a guide about that shortly.

thanks both of you for the tip. We have published an article about this
Does anyone know how to make the screen purple? In my case after pressing Volume down+Volume up+Power button phone goes into Firmware Update and it reboots automatically after that
Take the memory card out, worked for me
I don’t have a memory card? Is it worth me doing a factory reset before trying again?
It is worth mentioning I am only trying to unlock bootloader to remove carrier lock from my device.
I have previously successfully rooted this device, I just could never unlock bootloader.
It’s not about the memory card, there’s a folder called ‘dload’ just delete it.

Hi, i have some problem in the second part of the guide.
I have downloaded the ADB Toolkit but i can’t understand how to install it.
Can somebody help me?
hi. i can’t install adb toolkit correctly.
you tut is great. i successfully unlock the bootloader of my phone. tnx.
I have successfully got unlock code but in command prompt when i type fastboot oem unlock it displays that waiting for device help
No Matter what I do I cannot get fastboot or ADB to display my device, I did everything fine with DC-Unlocker it got my devices bootloader code but no matter what I cannot get fastboot to read my device, the best I get out of ADB is a question mark or nothing usually.
Ok, instantly after that comment ADB now displays my device but still fastboot shows nothing.
Ok I realised the problem was me executing fastboot at the pinkscreen(Vol keys and Power) and not the bootloader Huawei logo screen(Hold Vol Down and Power for 10 secs)
I have the same problem as you, but I tried holding Vol Down and Power and still fastboot doesn’t recognize my device. Any advice?
i have my bootlocker code and got to the adb toolkit but my computer doesn’t recognize it and it wont recognize fastboot any advise on this please
install USB drivers
I am a newbie to this and which usb drivers are these
install HiSuite. Search this web site for it. It will automatically install the USB drivers for your Y300
How about Y300-0000V100R001C17B171
Hello,
Please help me for ADP tool kit…………….i download but my system say Fix Adbwinapi.dll………..
please help me to unlock the phone…………
when u open the downloaded folder of adb-toolkit, u will see both the files adbwinapi.dll and adbwinusbapi.dll copy both files and paste in the location adb-toolkit\bin\files\. now the cmd above.
now run the command.
Try with C:\adb-toolkit\bin\files\fastboot.exe devices and it should work
Have been fighting with this over a day, getting the code was relatively easy, but have been trying to get ADB thingy to work all day and all last night, i type the first command adb-toolkit\bin\files\fastboot – it stops for a second and then starts onto a blank line, im guessing its not detecting my y300? It is sitting here with a purple screen in fastboot mode, but NOTHING i do will make it detect, and yes, i did download the drivers and install them. At a loss here and wondering if I’m permanently stuck with stock rom, someone must know what to do here
Well, I’m having a problem with getting the unlock code. The motherboard has crushed in my Y300 so it was replaced with the new one under Huawei warranty. With new motherboard new IMEI has come and so on. And now, nobody in Huawei or via DC-Unlocker can get me unlocking code- there is none (?!). So I ask u guys, is there a way to skip the process of getting bootloader code to install custom roms?
I start missing Samsung devices..
thanks .for the tips
it helped me
but i cant use my recovery mode …there is no response when i am using volume up / volume down
or when i try to touch the screen
and i cant swip to unlock it when t tells me to do so
when i type in the adb-toolkit\bin\files\fastboot devices into the command prompt nothing comes up, it just goes to a blank line, i take it this means my computer is not recognizing the device (as this command should list devices and no devices are listed) – ive tried all suggestions above, installed hisuite, all drivers are successfully installed. what can i do? please help.
thanks

Please i need help , in my folder “file” i have only

Franck,
fastboot devices is not a folder.
fastboot is the program, and devices is a command, just like the unlock command.
I dont know what you are running, but don’t run it like that. You should run cmd.exe, then at the black window you type :
cd c:\users\yourusername>\desktop\adb-toolkit\bin\files\fastboot devices
Or whereever you extracted the adb-toolkit.
Then you type “fasboot devices” or “fastboot oem unlock xxxx” .
Make sure your phone is in the bootloader Huawei logo screen(Hold Vol Down and Power for 10 secs) , and not the pink screen. Good luck!
What is going wrong?
I got my unlock code with DC unlocker (Huawei G510-100), but fastboot devices is always empty (no device found…) and getting with command fastboot oem unlock 1234567890…
Thx
@Applegate:
Do as Matt did:
“Ok I realised the problem was me executing fastboot at the pinkscreen(Vol keys and Power) and not the bootloader Huawei logo screen(Hold Vol Down and Power for 10 secs)”
Fastboot doesnt work in the pink screen.
Please read al lthe posts, it wil save you lots of headache.
Finally unlocked my Huawei G510-100, but what confused me:
Purple bootscreen (volume up+down+power) for dd unlock to find unlock code
Huawei Bootlogo Screen (volume down+power) for adb to enter unlock code with fastboot
Android green Bootscreen (volume up+power) to do android things?)
And I Always removed the battery before…
Please help!
The unlock code was quite easy for me to find, but the ADB thing doesn’t work for me. I extracted the adb-toolkit in my C:\Users\(my name) and entered the command “adb-toolkit\bin\files\fastboot devices”. Nothing happens exept for a blank line. When I enter “fastboot oem unlock xxxx(my unlock code) I get “Isn’t recognised as a command (or something like that, mine is in dutch and my English is so-so)
I’ve also tried the Huawei screen (Vol. down and power), but that didn’t do anything either.
Please tell me what to do!
Wow it actually worked! For some reason, it woudn’t work with one of the USB ports of my PC, but it did with anotherone! Thank you!
this don’t work ive got my unlock code but doing the adb thing it says adbwinapi.dll is not installed, ive downloaded the zip and extracted it but nothing, ive tried putting the 2 files in the bin folder but nothing
You said that we have to install the ADB Toolkit on the default location after downloaded. But I don’t know which one to choose to install the ADB Toolkit. Please advise. I’ve already extracted that Zip file.
No Matter what I do I cannot get fastboot or ADB to display my device, I did everything fine with DC-Unlocker it got my devices bootloader code but no matter what I cannot get fastboot to read my device.. it’s just saying “fast boot is not recognize’ i install the driver already
I try to unlock with dc unlocker dont work,error or phone not found.Whats the problem?I instaled drivers.
after all the unlock procces I can use my phone inmediatly?
Do i need a paid account to use this unlocker software?
Please help!
I got a unlock code but everytime I run adb I got message that AdbWinApi.dll is missing from computer. What I’m doing wrong. Thanks
copy the dll files
copy \adb-toolkit\*.dll to \adb-toolkit\bin\files
for those that cant get adb to work, here’s what worked for me:
Fastboot devices needs to be executed at the bootloader screen, not the pink screen. Hold Vol Down and Power for 10 or more seconds until the screen seems to be stuck on the logo screen. Then plug it in the computer through USB. The drivers should install. Once done, then run fastboot devices. This should work.
I have unlocked bootloader but can not unlock sim network lock. Plz help
Thanx all! May the methods damage my Y300?
I struggled with this software. It is not necessary. Use:
http://en.club.vmall.com/emotiondownload.php?mod=unlock&action=pre
instead. It provided me with an unlock code within seconds – no need for dc-unlocker software (or driver package that did not work for me). Then you can continue from the adb-toolkit steps with the code you obtained from the web form.
I can’t find the bootloader’s code! DC-Unlocker finds my Huawei g510 but says “Device in download mode. Need to restart”.
I rebooted again and again but nothing changes.
What am i doing wrong?
a me lo screen no diventa viola quando lo riaccendo schiacciando i 3 tasti perchè???
how do you install adb toolkit?
I have a win 7…
thnak you
Ok, works, but the tutorial does not mention that you have to go out of the pink screen and reboot into recovery mode (vol down power up) to execute the fastboot commands.
Furthermore the system does a initial setup. No problem since google backup restores everything. But the startup is something of a suprise.
it doen’t work with the huawei ascend y300-0100
error:
DC – Unlocker 2 Client 1.00.1074

sorry, this modem not supported

The manufacturer should be select: Huawei phones, not Huawei modems.
I have installed the driver package, but my device constantly is not recognised.
@Dangerous
Oh same problem here..
also this method http://www.modaco.com/topic/370878-mod-all-unlock-bootloader-directly-from-huawei-website/
of getting the unlock code doesn’t work anymore, the link simply doesn’t work..
I guess Huawei doesn’t support unlocking of the bootloeader for this phone anymore, I’m so damn pissed off, shitty company..
@Dangerous
In the options menu you need to go to the developers settings and activate USB error solving on your phone.
no device shows up when I type in fastboot devices
same thing when I typed in adb devices,
I downloaded PDANet and then adb devices worked..
fastboot devices still doesn’t work, what can i do ?
Unable to access pink screen, or apply update via dload on sd card. Y300 reports ‘Update exception. EMMC is readonly, you can’t update your system’.
Any thoughts how I may progress?
I GOT THE FIX!
okay, so make a new file in windows/users/(your pc name)/ make a new file in that callt adb-drivers.
when u open the downloaded folder of adb-toolkit, u will see both the files adbwinapi.dll and adbwinusbapi.dll copy both files and paste in the location adb-toolkit\bin\files\. now press the windows key+r and type CMD and put in adb-toolkit\bin\files\fastboot devices.
it worked for me!!
To everyone out there having problem with fastboot.
The instruction is this, press volume down and power FOR 10(TEN) SECONDS. If your release it immediately after the logo appear it will cancel fastboot and continue the normal boot.
Hi.when I use from dc unlocker,that show this massage for me
Devise is in download mode,need restart.
What’s the problem?
