Keep in mind, this method is not confirmed working if you're running android 2.3.x [ Gingerbread ]. So do not use this if you're running it. Also dual sim ones aren't supported from what I see it tempers with the phone, I haven't tested it but many have reported it doesn't work on dual sims.
Lets get started shall we? Firstly I have gathered up some useful resources that will help you get started. Make sure you read this guide first, from top to bottom. Then continue. As you must have a clear understanding on what you are going to attempt. If you have any queries don't hesitate to ask on the thread itself.

I have performed these exact steps and have successfully unlocked my bootloader and rooted the phone. So if you're worried. Don't be. After attempting this I haven't noticed any issues either.
Okay, first of all you will need to download Unlockbootloader ---> View attachment unlockbootloader.zip
Once you have downloaded the said .zip extract the .exe file inside the .zip to your desktop.
Continue by turning on USB debugging on your G300. if its already switched on then skip the part below..
Go into Settings>Developer Options and tick the USB Debugging option.
Once its switched on, plug your phone to the computer using a USB cable.
So far you've downloaded Unlockbootloader, have switched USB debugging on, and your phone is connected to your PC.
Now run the .exe file you have just extracted. Click "Root" and let it do everything, it will prompt up with a few warnings saying don't use your keyboard because CMD is running.
Once the setup finishes, your phone should be rooted.
Head into the app drawer, and if you see "SuperUser" you're now officially rooted.
Reboot your phone to finalize the rooting and exploits.
Ok, now for the bootloader.
Once your phone is on, and connected again to the PC with debugging mode on, run the .exe file again and this time click "Unlock BootLoader".
Wait for it to do its job, once done reboot again and you now have a Stock Rooted and Bootloader unlocked ICS phone.

Hi, assuming you have installed the g300 adb drivers, once the device is hanging on the boot logo and you connect the usb cable. You need to wait for windows to fully the load the adb driver before you use the unlockbootloader.exe program.

What you have to do is,turn on debug, then power off device fully by pulling off battery then putting it back in, now you must power on by golding the volume down button and power button at the same time, this should get it to be stuck on the huawei logo screen, now plug in your USB cable and wait for you PC to detect the phone and it should automatically install the devices driver's, one its done the now open the folder and run .BAT files, If you are experiencing problems here's a link for another guide : View

Hi,
After the "Unlock BootLoader", my phone doesn't boot. When the logo appears it stars to reboot again and never goes beyond that.
Any ideas ? Have I killed it ?

Turn ur phone completely off. By pulling out battery then apply the battery again.
Now hold volume down and power button and it should be in boot loader mode. If ur logo is stuck well this is in boot loader if not and it continues well.. idk

Hello krishneelg3,
I have tried a method on http://huaweig300.com but I'm stuck with the problem.
Installing USB drivers/Root/Backup IMEI went OK. Then by mistake I skipped the Step on page 5. Check Baseband and kept continued by Bootloader & ClockworkMod all went OK until the step 10. On page 6. After executing BootloaderG300.exe the phone rebooting cyclically, My operator screen appear for a approximately one second and the phone restarts again. How to resolve the problem and is there any hope to return to official ROM?
Thanks in advance, I really appreciate it.

What was ur baseband and were u running gingerbread?
If u r on official ics then this guide is for u, if not notify me.
PS : If you are running Gb I refer you to look into this guide, as long as your phone can boot into bootloader your fine, and I'm sure it will boot into Bloader mode : http://www.modaco.com/topic/353386-how-to-root-your-huawei-ascend-g300-for-windows-mac-and-linux/

Thanks krishneelg3,
my baseband is 109808, and I'm running GB.
The problem is that I don't know if I'm in a Bootloader mode when I see a pink screen?
When I press VOLUME DOWN + POWER it starts same as when I press POWER, first logoo (in my case picture of my operator) it lasts for about few seconds, then phone reboots and start doing it cyclically.
The other thing is that, when I press VOLUME DOWN + VOLUME UP + POWER, it then turns into a pink screen.
In that state (pink screen), when I plug in my phone to my PC, PC recognize my phone without reading sd card or internall memory.
So what should I do?
Thanks man, really appreciate it!

Guys,
I solved the problem.
I've just followed the instructions in step 5. on the site http://huaweig300.com and put a new update.app (1 KB) and copy it to the dload. After that I've used main dload (ICS folder, aprox abot 600 MB) and everything updated and installed successfully.
Thanks.
p.s. if anyone has or had the same problem, do not hesitate to ask.

hi all
sorry to hijack the thread
I have just got my son an ascend 300 which is locked to vodafone
its on android 2.3.6
the build number is
u881v100r001c02b892
i have a download of HDU88151079V100R001C00B934 which is the ICS but i dont think that will work for my build
ideally i want ICS but dont mind too much waiting.
but i do want to be able to get of all the bloatware.
I guess i need to root to do this.
the link to the modaco site is down and it seems this is for those lucky enough to be on ICS
would i be better off upgrading to ICS then following the method above or would i be better finding a method to root under gb (If so where)
many thanks

OK get the official pics update b927* must be that build.
After its done downloading, extract its contents to your memorycard of the phone.
Make sure the update.app is in the root of SD card .
Then power off phone, remove battery re apply battery and hold the three buttons "volume up, volume down and the power button" until a screen pops up it will then install the stock ics once its done it'll reboot twice.
If only one it doesnt matter.
Setup the phone. Now to install b934 or newer versions use cwm for dazzozos repacks or the update force method. But I advice u to look for help on modaco. Thanks.

Thanks for that by b927* you are referring to a different version of HDU88151079V100R001C00B934 ?
where would i be able to get this from?
so this would give me the stock ics
what is the advantage of then installing HDU88151079V100R001C00B934 ?
Thanks

Your on gingerbread so your baseband Is 109808 and if u flash any b934+ stock using the combinations say goodbye to your phone. I did that to my brothers and it bricked.
So to get to ice you must install b927 version of ics then your baseband will change to the new one *2030* now you can flash any b934+ stocks because you now have the new baseband.
Go to modaco and enter the G300 forums and look at the first dew pages all the info and guides you need. Procedure is simple.

Best method to unlock zenfone 5 bootloader without any freeze/random reboot!

I'm using RR 5.6.9 by @tank0412 for last one week.
http://forum.xda-developers.com/zenfone-5/development/rom-resurrection-remix-mm-5-6-7-t3357331
So far I didn't face any freezing or random reboot issues. What I did is as below:
1. Flash/downgrade to UL-ASUS_T00F-WW-2.21.40.30-user firmware.
If you know how to flash stock firmware then skip step 2-12 and just flash it by yourself. These steps are for new users.
2. TURN OFF the device. Press and hold Volume Up+Power to enter to fastboot/droidboot. When the ASUS logo shows up, release the power button and keep on pressed the Volume UP button. This will take you to droidboot/fastboot mode.
3. Check whether your PC detects the fastboot...
Code:
fastboot devices
if not, go to device manager and install the fastboot driver(by online). if fails, install from the PC by selecting the android device from the list.
4. Download this image UL-ASUS_T00F-WW-2.21.40.30-user.zip: http://dlcdnet.asus.com/pub/ASUS/Ze...user.zip?_ga=1.61130092.1708615694.1457697474
If you have different SKU, you need to find the right firmware(version-2.21.40.30) here: https://www.asus.com/Phone/ZenFone_5_A500CG/HelpDesk_Download/
5. Extract fastboot.img, boot.img, recovery.img from the zip file and copy to ADB folder to flash. Copy UL-ASUS_T00F-WW-2.21.40.30-user.zip to ADB folder as well.
6. Run the below commands:
Code:
fastboot flash fastboot fastboot.img
fastboot reboot-bootloader
wait for reboot.....
Code:
fastboot flash boot boot.img
fastboot flash recovery recovery.img
7. Then go to recovery by selecting from the menu, you will an android logo with "!" sign. Press power+vol down+vol up sequentially and simultaneously, don't release any of the buttons. You should be in recovery mode.
8. In the recovery, select wipe data/factory reset
9. Select wipe cache partition
10. Select apply update over adb sideload
11. Now check whether your PC detects the ADB over USB. if not, go to your PC's device manager and install the ADB driver online. if fails, install from the PC by selecting the android device from the list.
12. After successful detection, run below command
Code:
adb sideload UL-ASUS_T00F-WW-2.21.40.30-user.zip
13. Download this official tool for Unlock Bootloader: http://dlcdnet.asus.com/pub/ASUS/Ze...rel.zip?_ga=1.117083014.1481752799.1464212721
A501cg users should get the tool here: https://www.asus.com/Phone/ZenFone_5_A501CG/HelpDesk_Download/
14. Extract the downloaded file and copy the .apk file into you SDcard. Install that .apk(if it says untrusted app, then go to settings>security>enable Unknown sources).
15. Run the installed app and press unlock. wait and let it reboot. After this, your Asus splash screen will become white & bright.
16. Now do a clean flash for any custom rom.
You guys can try it. :highfive:
Note: Few users are having "No Camera" issue for unlocked bootloader. This method will not fix that. Sorry about it, I'm a victim as well.

First of all, please don't quote the whole OP while you are replying.
Yes, it won't work for your device as you have a501cg. You need to get the official unlock tool from this site: https://www.asus.com/Phone/ZenFone_5_A501CG/HelpDesk_Download/
Before that you have to flash or downgrade to *.30.zip firmware.

Actually a501 has the SAME unlocker as a500cg. There's only one app that unlocks a wide variety of Asus devices. (Zen6's different afaik).
And we tried to install 2.21.40.30 for base as well and it changed nothing.
And unlocker application doesn't change the working mechanism of phone (we decompiled it).
So, are you sure that you tried to use heavy applications like Youtube or some games?
If you get any user that reports freezes gone; i will try it again with your method.
Thanks for your contribution. Good luck with your method. :laugh:
Btw assuming you have a500cg, that phone can be fixed imo.

Bro, I'm a heavy user. Many of us had faced forced close for 8 ball pool game. I had it too but after this method no forced close happened again. I'm not sure whether a500cg and a501cg have same app for unlocking. It's a bit confusing to me as they have different sites to download their firmwares and tools. But I'm sure, what ever the phone is a500cg or a501cg, the tool will work if the user has *.30.zip firmware installed.

Yes because the tool seeks for if.bin on firmware folder and it copies to the sysfs. (You're doing same thing on fastboot when flash ifwi if.bin)
So that's why I don't believe the unlocker tool fixes something.
Anyway, thanks; I will wait for another users that solved the issues with your method and then take a look with my phone.

You are right. Most of the cross platform developed apps are crashing. It seems like something is wrong with the JavaScript's render engine. I don't play with ROMs. Hope ppl will come forward to have a fix. But to my utter surprise it's been 10days, I still don't have any freezing.

Before, following your method with 2.21.40.30-user.zip was not success, but downgrade to 2.22.40.540-user.zip is ok. Unlocked with black logo, white ground but can not flash TWRP, how can install cooked ROM?

My phone is Asus Zenfone 5 T00j A501CG WW. It has 1.6 GHz CPU, 16 gb internal, 2 gb ram. Can this method work if I get the stock firmware you mentioned?

Hi I am new to Android, I follow the steps as mentioned. But not able to after step 7(Press power+vol down+vol up sequentially and simultaneously, don't release any of the buttons. You should be in recovery mode.), I am not go to recovery mode. The phone goes power off mode and is not starting again. Any help is appreciated.

Help about Pixel C !!

Hello,
This is the third time I've asked you for help. This time it is, it always concerns google pixel C. Everything worked so well. But today, by simply taking a picture, the device turns off and on again on the google logo. Then the android robot with a red alert appears. the word "No command" just below. I can navigate the recovery. But impossible to go into "android recovery" with the menus to apply sideload ota.... I sincerely think it is brick and I'm really very afraid that I won't be able to use the guarantee despite having locked the bootloader before. I was on the official Android 7.1.2 software. The adb and fastboot commands detect the tablet. But I can't unlock the bootloader or flash... I have no idea what to do, I could use your help please!!!!!!!!

The adb and fastboot commands detect the tablet. But I can't unlock the bootloader or flash... I have no idea what to do, I could use your help please!!!!!!!!

Have you tried this?
"Turn off GOOGLE PIXEL C. Press and hold together : Power Button + Volume Down until Logo appear at LCD screen. If we see the menu at LCD screen, choose Wipe Data/Factory Reset with Volume Button to select and use Power Button to ok or enter."

Are you sure I can do that? Because I had downgraded Android from version 8.1.0 to 7.1.2 because I had a problem with 8.1.0. Therefore I had unlocked the bootloader etc.... So the data had been erased! If I do a wipe data/Factory reset will it work at least at 90/95% ? Despite having only installed the Factory image (without OTA) can it work without doing a bootloop or other...?

Well, I tried and I always fall back on the page with the robot and the inscription "no command" just below. I'm sad ?

If the bootloader is unlocked you maybe have a chance by install TWRP and then install LineageOS 15.1 (wich is much better than stock).

The bootloader is locked. This is the end. Is there any advice I can try to send it to the after-sales service?

Tell me, the OTA file is used to apply an update, right? Because I tried to do this manipulation but by downloading Exactly the same software and it didn't work. So if I try with a more recent version of Android, it should work, right?

Sorry, but I don't know this. If the bootloader is locked I have no further idea.
Maybe somebody else has an idea???

Okay, I found the solution. The OTA image had to be installed. I am happy. Everything seems to be working for now. And yes, the ota image can be installed without unlocking the bootloader!

Perfect!

How did you fix it
I had the same exact same fault in December and couldn't work out how to fix. I thought my tablet was just a paperweight now but would be so happy if i could fix it.
do you have a link to the method you used or can you provide more details on how to fix?
what do you mean by the OTA image had to be installed?
Each time I tried to copy the image from my computer to the tablet it failed.
would be grateful for any help.
thanks

Hi, if your device is a C pixel, you can try to check it out here: https://developers.google.com/android/ota
To sum up, my problem was the following: suddenly, my tablet could no longer boot on android but on the page where the robot was displayed with a red panel and the indication "no command".
And the solution was the following: being on Android 7.1.2 I had to download Android 8.1.0 for the "update" to work. So I followed all the steps indicated by the site I provided you. That is, having Fastboot and adb working, then putting the.Zip file of your android in the same folder as adb and Fastboot. Then you follow the different steps shown on the site to download the ota image. My explanation is not great so if you have a question about something specific let me know. And if you can send screenshots of your worries it will help.
Good luck with that!

Move the stock rom to the main folder on the phone. You need to download the rom firstly from this site but do not follow the instructions.

but now i have a new problem. when i shut off the phone and then push volume up+power button i enter into a menu that looks like this. what am i doing wrong?

ok so when i push volume up+power i come into the first menu and if i push volume down+power i come into the second menu. the problem i have is that when i select "boot to recovery mode" it just brings me back into the first menu here are the two screenshots. where do i need to go exactly to update?

ok i think i found out why i have no update options in my recovery menu! look in my screenshot there it says that DEVICE STATE - locked. i think it means that the bootloader is locked and therefore i dont have the ability to flash the rom. unfortunately i dont know how to unlock the bootloader. all i know is that i first need to activate OEM unlocking in developer options (which i have done). but from here i dont know how to unlock the phone. could you please help me unlock my phone? thank you for the time!

Question urgent help plzmy Pixel 6 Pro doesn't work

I received this Pixel 6 Pro this morning. I want to get root privileges， after a regular ota upgrade, I did the following steps: Unlock the bootloader (successfully) extract the system boot file, give it to magisk (25.2) for repair, and then flash the repaired file, But I can't flash in, like in the photo, fastboot boot/flash boot. I have tried many times but failed without exception. Up to now, my Pixel 6 Pro is stuck on the bootloader interface, but I cannot press the power button to start the phone(power button is OK）, and I can still use the volume buttons to select the boot option. But now the phone can't connect to the computer...the computer doesn't respond...what should I do (make sure all the file is correct)
plz help me...

I think it depends on which environment you have in your computer.
For instance, windows then you just need to download .exe file ...etc.

Entering its main page and there is instruction how to use it(https://github.com/badabing2005/PixelFlasher).

You can just boot to fastboot and boot the image
Code:
fastboot boot "magiskpatchedimage.img"
Then when it boots, direct install in the magisk app.
