Hello Everyone,

Below is a tutorial I have compiled and translated from bbs.anzhi.com on how to update your Huawei Ascend D1 Quad XL (U9510E) to the latest version of Android offered by EmotionUI, Jelly Bean 4.1.2:

First of all, I want to give credit where credit is due:

genokolar

(aka G大) - Creator/Modder of the Custom Recovery for this, and many other phones coming out of China

Ry09iu

(aka R大) - Creator of a Rooted ROM based on EmotionUI B534, which is based on Android 4.1.2

【LUV】

- The board moderator for the D1Quad section of bbs.anzhi, also who's ROM release I used for my phone, but it's upto you to choose which one you want to use

**IT IS NOT RECOMMENDED FOR YOU TO ATTEMPT THIS IF YOU DO NOT HAVE A PREVIOUS EXPERIENCE WITH FLASHING PHONES. IN THE CHANCE THAT YOU BRICK YOUR PHONE, I CANNOT BE HELD RESPONSIBLE FOR IT**

**DON'T FORGET TO BACKUP YOUR FILES!!**

Now that the credits and the warning are given, let's get started:

3.

GApps [Jelly Bean 4.1.2 (Author goo.im/gapps)]

: Download

*The roms are hosted in China so the download will be slow, please be patient and your download will be done in an hour or two :)*

**PLEASE PLACE THE ROM YOU WISH TO UES INTO YOUR EXTERNAL SD CARD BEFORE CONTINUING**

Step 1: Flashing Custom Recovery

1. Turn-on USB debugging on your phone [Settings -> Developer Settings -> USB debugging]

2. Plug in your Phone to your computer via USB for it to install the appropriate drivers*

3. Run recovery6.0.1.4_AscendD1Q.exe

3.5 If your system locale is set to anything other than Chinese, you will get this:

But what you should see is this:

4. Type in "1" and press Enter -> This Recovery Flasher will do what it's made to do and when it's completed, your phone will now have a custom recovery.

5. The application will automatically close 10 seconds after the Recovery has been successfully flashed.

*If the drivers do not install properly, please download the driver attached in this post and install it manually.

Step 2: ROM Flashing

1. Boot your phone into the new recovery. (either by starting the application again and selecting option 3, or press and hold the Power Button with Volumn Up)

2. You will be greeted by the Custom Recovery Screen show below:

3. Scroll to select option 3 (Wipe data), confirm the wipe

4. Scroll to select option 4 (Wipe cache), confirm the wipe as well

5. Scroll to select option 2 (Select zip to flash/install)

6. Scroll to and select option 4 (Install from external zip)

7. Scroll to and select the zip file of the ROM which you have previously downloaded and placed into your external SD Card, confirm the flash

7.5. At this point, you can either flash in the gapps right away, or flash it after rebooting into the OS. I chose to flash it after booting into the OS for the first, but I don't think it will cause any problems. I will be posting the way I did it, and if you guys did it the other way, let us know if it worked or not

*IMPORTANT NOTE*

When you're booting up your system out from Recovery, you will be asked whether or not you would want your ROM to auto update the recovery, shown below:

Please

select

the one being highlighted in the image, which is

option 2 ([*] Cancel - Back)

.

OR CONSEQUENCES WILL NEVER BE THE SAME!

Step 3: Flashing GApps

1. Boot into recovery

2. Scroll to and select option 4 (Install from external zip)

3. Scroll to and select the zip file of GApps you have downloaded "gapps-jb-20121011-signed.zip" or whatever you may have renamed it to, confirm the flash

4. Reboot into OS

5. *THE NOTE ABOVE STILL APPLIES, SO HERE IT IS AGAIN*

Step 4: ALL DONE!

Congratulations, assuming everything was done properly, and everything worked out, now you will have Android 4.1.2 on your Huawei Ascend D1 Quad XL.
