Default [Q] How to Unlock bootloader of Huawei Ascend G525 and install German firmware

Hi,
I got the Huawei Ascend G525 as a gift from brother in law living in china, and now I am in a bind that it does not have the google play, i installed it using the apk file for google play but the whole UI is in Chinese settings , and the usual Chinese OS version issues for english user >_< , I managed to find and download German firmware (sorry forgot the link to post where it was) and tried to install it but the update failed. Further research led me to believe that i have to unlock its bootloader and I tried to use the method on huawei site (using adb toolkit) but for that i need bootloader unlock key and the site options to get key from huawei does not have G525 in list, so I am back to square one, Please let me know how i can unlock bootloader of Huawei G525 and if there is a new firmware I can use or something like flashing phone rom with Odin (I did flash my galaxy tab 2.0 with odin with new UK firmware)
The Android version is 4.1.2
and firmware file name, i download is Ascend_G525_firmware˙ G525-U00,Android 4.1,Emotion_UI,G525-U00 V100R001C00B188,West_Europe
my mobile current firmware is G525-U00V100R001CHNC00B180
Please any help will be useful.

If you tell me the block name of recovery I will make backup for you
Until I┤m not 100% sure which block it is I will not replace stock recovery against cwmr.

my fear is, that we both have problems for flashing.
The unlock code for the bootloader you can get from huawei directly.
I tried this on my European version, but this will not be offered from Huwaei ( only chinese versions).
So I┤m still not able to flash chinese Rom (b191) or any other Miui or Lewa Rom ,...

I also confirm the lack of bootloader unlock request in Huawei's website.
What did you do to get the bootloader unlock code? Did you send an e-mail? Where?
I also find myself in a dead end, because I try to get a backup of the current ROM in the phone, connect succesfully through adb (downloaded drivers from here ) however following instructions from here:I can not connect the device with "fastboot devices" (i get to Huawei Device devices in windows device manager with yellow exlamation mark and the phone has been booted in a pink background, i think this is the bootloader mode because I have done it with all three buttons, power, vol+, vol-). Do you think this is a locked bootloader problem?

Default Late reply and updates

Hi,
Sorry for not following post, (i think i accidently turned off the option to inform me of new replies via email)
I tried emailing to both the german support email and the chinese, chinese support email gave me no reply even though i mailed them 3 times, but german one did and said that my phone is from china so they can't provide any support,
I tried to talk to them on facebook and local Huawei support center, facebook, no help, though someone else was willing to him and thanks to him poiting to way how to install english super use i am able to see almost all system messages in english, and as for the local support, since its not launched here they said they can't do anything,
The problem at hand was that it was not launched any where else, so no english version firmware i could find,
I almost bricked phone when i played with the "sorry forgot name" sytem file where it said to include the contact mismatch to 10 so that i can see the contacts name in the messages (its from china so least match is 11) and thanks to my luck i was able to upgrade firmware to b191 from b180 on 3rd try and since then i am scary cat to do anything with phone,
and now i read that its being launched in UAE, so looking forward if they put new firmware download on english website, (hoping they dont wait for an update to put it on website and put the current stock one)
please update me if you can get your hands on new english firmware , ty

I send a short Email to mobile@huawei.com asking for the unlock code on saturday 7-12-2013.

Dear sir/madam,

I tried applying for a bootloader unlock code at unlock url which I cannot post because of XDA forum restricting me, but my device (Ascend G525) was not listed. I supply the data via this mail in the hope to get a bootloader unlock code via this way instead.


Product Model: Huawei Ascend G525

SN: ****************

IMEI: ****************

ProductID: ****************



I hope to hear from you soon.

Yours sincerely,

******************
I immediatly got a response from Huawei on monday.

That's the good news, the bad news is that as far as connecting to my device I got as far as you got. As I'm on Ubuntu 13.04 64bit I added the usb rule needed for Huawei devices. It shows up when I execute "./adb devices". When I boot into hboot/fastboot mode by pressing the volume buttons and the on button I get the pink screen, but it does not show up when I run "./fastboot devices".

Anybody who knows how I can get fastboot to connect to a Huawei G525?

My bad, I thought I was starting the device in fastboot mode, but the pink screen denotes the download mode. I looked up the instructions to start the device into fastboot mode at sigmakey[dot]com. The complete list of steps that I followed were
  1. Remove battery for >= 10 seconds
  2. replace the battery
  3. hold volume down and power button
  4. when the screen locks on the Huawei logo you're in fastboot mode
  5. connect the device via USB
  6. run:" fastboot devices" and see if it's listed
  7. run: "fastboot oem unlock [unlockcode]"

Default HUAWEI ASCEND G525 bootlock?

Got my phone 6 days ago. Rooted it.
Third day I messed it up by deleting languages (stupid, but selected them with a cleaner & removal tool).
I formatted a micro sd card, downloaded original firmware, started up in the installation mode but while busy unpacking, "installation failed".
Is it because of a bootlock? or is it something else.
Is there an boot unlocker for download for the G525? The phone doesn't start up, so I can only work out of the boot menu or sd card.
All tips are welcome.
