From EMUI_3.0_for_P7-L10

1. Force update using EMUI 3.0 stock recovery the P7-L05-L07_EMUI3.0_Android4.4_V100R001C01B604 or P7-L05-L07_EMUI3.0_Android4.4_V100R001C01B606 on your P7 L07-L10 B604. (Just wait until it finish with error. Just ignore and let your phone boot). Note: If you are using CWM, flash EMUI 3.0 Stock recovery first using fastboot, if not just ignore and continue this step).

2. Next force update with dload_3.0_down_2.3. (Also, wait until it finish with error. Ignore and boot your phone again).

3. Next force update with P7-L07-L05_EMUI2.3_Android 4.4_V100R001C01B125SP03. (It will update using 2.3 stock recovery, just after a few second it will boot again into emui 3.0 recovery (sometimes it will hang from 2.3 stock recovery, just power off your phone and power it on again and it will boot into stock recovery 3.0 updating your phone). Just let it finish and an error will occur. Just ignore and turn your phone off and boot it again. Finally, you are in 2.3 firmware but you are still in L07.)

4. Next force update with P7-L10_V100R001C00B135SP03_BACK_TO_L10 and let it finish. And finally you are in 2.3 firmware with L10. (At this time you can now install any L10 2.3 firmware. But this firmware is a –test version only.)

5. Finally, install L10 firmware you want. Like: Huawei_Ascend_P7-L10_V100R001C00B135_Israel_Android_4.4.2_EMUI_2.3 or B138.

Good Luck!

Much easier to downgrade from EMUI 3.0 is install EMUI 2.3 ROM like B135/B138 via ADB .
Flashing on images:good:

Yes, I know that. 'Coz you only have to flash images using fastboot. But let me ask you, flashing images using abd/fastboot, will 2.3 stock recovery works? I will answer that, it is NO. Now, since the stock recovery of 2.3 is not working, do you think it is the correct way to fully revert back EMUI 3.0 to UI 2.3? The TUT will fully revert back your EMUI 3.0 to UI 2.3.

Anyway, I just posted this revised TUT just to help. Still users have a choice which way they will use.
1. The easiest way by flashing, but not fully reverted back 'coz of not working 2.3 stock recovery.
2. Or the hardiest one (needs patience) which 100% fully reverted back to 2.3.

I just wanted to say THANK YOU!

After the update to 3.0 failed I tried a lot of different methods, but this ultimately saved the day!

Hello

Can you help him?
B609 is now on my phone, and I want to return to the factory, B133 was back.
P7-L10 (Hun)
Before it was the official B133SP01 it.

What is the solution? As described above tab through all the steps to do it?

Or is it just the "dload_3.0_down_2.3.zip" should flash and then go up the B133 stock rom?

How do I do that?

(pls.sorry for my english)

does this installation revert to fully functional stock b133?
2.3 recovery, 2.3 boot.... ?
one step only and you go back?
One of my friends tried this approach before I could have done that.

In the meantime, it has come to the phone switched off, and then on and off again. Did not stop the process.
Then power button is turned off. He has now reached a point where the recovery is emui2.3 above. However, none of update.app not run. Neither the B133 or B609. In each FAIL get feedback.

ADB is unable to use recovery mode.

I do not dare to start the downgrade to the 2.3 was not to become a brick. I'm afraid to ruin the phone.

Do you have any advice on this?
