Guide:Install KitKat International B510 ROM to B506/B507 firmwares

This method worked for me.I had in my p6 the chinese B507 firmware with stock recovery and no root..I believe that with B506 is tha same way..(Do it with own risk..)[/B]
Ok..Lets begin..
a) Download P6 B510 Official zip
b) Download P6_Unicom_EMUI2.0.zip
c) Download P6 B132 Official zip
The steps
1)Do a factory reset(I dont know if that is necessary but i did it)
2)Install P6_Unicom_EMUI2.0.zip via Local Update(Extract dload folder in internal storage)
3)Install P6 B132 Official zip via Local Update (Extract dload folder in internal storage)
4)Rename the B510 zip to update zip and install direct the update zip again via Local Update(Don't extract anything from this)
5)Do a factory reset again if you have problem with batery drain or something else(Of course is optional)
This is the process that i follow without any problems
I couldn't post the downloads sites because is my first post
Sorry for my English..

Where do I download the required files?

Take out your sdCard, re-unpack the download you are using...sounds like it didn't unpack properly....put the update.app back in your sdCard in the dload folder, and restart your phone.
It does take a long time to boot and load but 25mins is to long. At most 10.
And don't worry, I've discovered that it's pretty difficult to brick this phone.

It happens sometimes. Just make sure you have the B132 (if that's what you want to flash back to) or the B510 (if that's where you're going) update.app in the dload folder in your sdcard and restart your phone.
Both take a while to get done so be patient. If it takes more than fifteen minutes however, restart your phone again. Make sure you have a full battery.

still having problems...
Sorry to bother you guys again, but i seem to keep failing in this normally 'simply task'...
See attachment for phone stats
So this is what i do:
1) downloaded the B510 from here: h**p://huaweinews.com/2014/06/ascend-p6-b510-official/
2) unpack the zip file (update.app, cust, meta-ing, patch, system are inside the folder)
3) I copy the update.app and paste it in dload on my external sd-card (transferring trough usb cable)
4) I'll go to the update app and click 'update from local'
5) There comes a pop up that mentions -shutting down- behind it I see a other pop-up telling -wrong- can't read the rest since it is behind the shutting down pop up...
6) applying update:
-checking sd update pkg...
-huawei sd card update fail.....
-cust copying files...
-copy cust files successed
FAIL
Does somebody know what i'm doing wrong? Would be really Thankful!!!

Well done actually!! All your steps are correct, and it's very easy actually!
You're on B111! Find B125 (Huawei news or Huaweiblog), repeat exact same steps.
Then do the same with the B510 update, you'll have no problem. And you're lucky the update REALLY rocks when you take it all the way from the original B111.
Enjoy, and let us know. One thing - I found that with B510 they remove the colour temperature slide from the settings menu.
I love my screen crystal clear and cool so I set mine on max cool and then flash B510.
So take a look at that and set to your taste beforehand. Onward!

Ascend P6 B510 Official Android 4.4 KitKat Update Released in Europe

According to the latest reports we received from our readers, Huawei is finally pushing out official Android 4.4 update for people in some European countries such as Hungary,Romania and Czech Republic. This new B510 update seems to be the same one pushed to registered beta testers in Germany not too long ago. There is speculation and rumors going on that Huawei rushed and outed the beta firmware as official one, but knowing Huawei’s numbering scheme B510 still could be the final official one intended for release in Europe.
Here are some details about this official firmware
Compatible Model – Ascend P6-U06
Firmware version – B510
Android version – 4.4.2 KitKat
Emotion UI version – EMUI 2.3
Kernel version – 3.0.8-00787
Size – 775MB
Region – Europe
English language is included
We won’t go through describing the changelog here because you guys have probably know the changes by now because of the leaked and official Chinese firmwares. Basically this update brings the new EMUI 2.3 user interface and few new software additions to the camera and power saving features.
Again we still don’t know why Huawei pushed B510 firmware as a beta one to Germany and as a official one to others. The download file below is obtained from the official B510 release and not the B510 German beta release. So if future proves that both B510 aren’t the same you can be rest assured that we have provided you the official release.
Make sure that you are running B132 firmware before installing this new B510 release. This B510 was pushed to the users running official B132 firmware http://huaweinews.com/2014/03/ascend-p6-b132-firmware/ and early adopters of B510 reported us that B510 won’t install correctly as the previous leaked KitKat firmwares unless you are running B132 prior installing B510.
Download link - http://dl.huaweinews.com/Roms/Ascend-P6/B510.zip
Please report the issues and your thoughts about this firmware in the comments below so other readers will be aware of it.

arabic
dose it include Arabic keyboard

How we can delete the Omni ROM and go back to B132 in order to try this release ??

yes...if someone can do what Reyncla did..and make a b132 if not the original b510 (the one here) that we can flash from twrp...that would be nice
i am trying to get the original rom on to the phone and it doesn't work...maybe i am not using the correct recovery for the correct rom ..i do not know..i will keep trying and tell you guys if it works

I cannot update to 510, i'm on b132... i tried OTA update and local update, none work for me...when it boots in recovery mode i get an error 7 something about music2.apk...i tried the download link ota download...but nothing...same error. I tried factory reset, wipe cache partition...still nothing...any ideas?

Hello !
This update work only for Stock Huawei Firmware B132 JB and also for Stock Huawei Beta B510 KitKat !
If you have issue to update from this two stock firmware, it seems that your stock rom in your device was modified , so you should put all the files back .
For all device already updated to KitKat but not Beta 510 , you can downgrade by installing a intermediate step ( update.app ) . Only now you are able to flash Stock B132 UPDATE.APP by /dload method .
For all device already updated to OmniROM KitKat 4.4.3, you can directly downgrade to B132 ( without install intermediate step update.app ) .
Put UPDATE.APP from Stock B132 in external sdcard/dload directory, also you should put back stock boot.img & recovery.img ( for B506 ) from second post TWRP 2.7.0.0 ! After these three steps you can downgrade by pressing combo key . ( Before put back stock recovery from B506, please go to TWRP recovery and wipe : cache, dalvik-cache, cust, data & system ) .
Good luck !

Nop, you shouldn't wipe Internal Storage on TWRP ! I already downgraded ( and more than once ) from OmniROM 4.4.3 directaly to UPDATE.APP from B132, but wiped all without Internal and External Storage .
Now , you can try with intermediate UPDATE.APP before flash UPDATE.APP from B132.
Good luck .

Is very simple mate, but I don't know if you understand ..
So, please put OmniROM 4.4.3 on your device !
- copy UPDATE.APP from B132 to external sdcard/dload folder ;
- go to TWRP and wipe : cache, dalvik-cache, data , cust & system !
- reboot to bootloader from TWRP !
- flash stock boot.img from B506CN ( fastboot flash boot boot.img )
- flash stock recovery.img B506CN ( fastboot flash recovery recovery.img )
- reboot your device ( fastboot reboot )
- now try to flash UPDATE.APP by combo key !
That's all -> now you are on Stock B132 !

Hi
Try to flash your B510 custom and flash with adb the B510 stock recovery in the second post here > http://forum.xda-developers.com/showthread.php?t=2709353 .

Because if you flash TWRP (for KK) then a stock recovery B118 (for JB) it's normal it's don't work. And if I don't say something wrong B118 is a chinese version.
Good luck

Ok i'll try this now....

Just use another kitkat recovery image to update. In my case,

[HOW-TO][GUIDE] Downgrade 4.4 -> 4.2 / Change from Chinese to International ROM

Since everybody knows how to upgrade OTA or from LOCAL UPGRADE and go from 4.2 to 4.4 I've decided to let you know how to easily downgrade from 4.4 to 4.2 AND / OR change from Chinese to International Huawei Firmware!
The method I describe here, I've found in some German forums after long search. It really works! 100% tested on my device Ascend P6-U06!
!!! CAUTION !!!
Before you begin, you must be sure you have STOCK recovery, NOT TWRP one!!! This flashable files work and can be flashed only thru STOCK recovery!
If you have TWRP recovery and don't know how to go back to STOCK one, look the SECOND POST in THIS thread and follow the steps there, before you begin this procedure! ONLY after you're done with turning back your STOCK recovery and you're sure of that, you can continue with the following steps:
To Downgrade from Android 4.4 to Android 4.2 / Switch from Chinese to International ROM, do the following:
1. Download this (Unicom 2.0 Downgrade Flashable ZIP) and flash it thru STOCK RECOVERY - https://mega.co.nz/#!ZYVixBqa!JNMLRB2DUVKlGpZVqPJbIsdbVPijks7r1Mtk46KGrmE
This is a 240MB archive, also known as Unicom 2.0 - something like ROM, but it is not an entire ROM, but just part of it, that must be flashed thru stock recovery. You must unzip it, take the dload folder that is inside and put it on you sdcard. Than you can flash it like a local update thru the updater, or you can forcefully flash it - pres power+ volume down+ volume up and it will take you directly to flashing updates thru stock recovery. When you flashed it, you can once again boot normally into you Android device. Now you must take dload folder from the B132 zip (from the link below), once again put it on your sdcard and flash it again using the same methods again thru stock recovery. The cool thing is that the first little flashable zip allows you not just to downgrade from 4.4 to 4.2, but also change from China to International ROMs. So when you're finished flashing this thru stock recovery, flash the official international B125 or B132, wait for the system to install and boot into android. When it is finally booted, you can flash B510 or B512/513 - whatever you want. In my case when I downgraded to B132, after the first boot the system prompted me, that it can be updated directly to B520 OTA. I've updated and now I am once again with International firmware​
2. Download this (B132 International 4.2 Firmware) and flash it thru STOCK RECOVERY ONLY if you already flashed the file in the step above! - https://mega.co.nz/#!5JkAzKpB!nFqfHIHfWo6EO4XPqjO3Gga6a3XWWnqqZxZDZpzAdWE
3. Boot into Official Huawei Android 4.2 firmware and check for update OTA. If you have one - install it. If you don't - you can flash B510 or B512/513/etc...
Enjoy International firmware line again! This method can also be used just to downgrade form Android 4.4 to Android 4.2!
Files are not flashable thru TWRP - please, use ONLY Stock Recovery!
------------------------------------------------------------------------------------------
Please, hit THANKS, if this thread helped you!

question: which stock recovery should i take if i have b635 (there is no available official b635 rom - only repack)..
i want to downgrade because i want to get the b520 fw..
maybe you have an advice..
thanks in advance..

Just try with the stock B510 recovery from the second post in the TWRP recovery theme! I think stock recovery is the same for all 4.4 ROMs and it doesn't matter which one. I recommend the one that I told you about! Should work! I was with Chinese B706 ROM and TWRP. To downgrade I've flashed the B510 stock recovery first and then - step by step as I wrote above.

thanks..will try to do that..

I have a question for you - I see that you modified the .prop file for the local channel, to get louder sound in headphones (from your signature). I've tried to do this today, but when I try to modify the file every time it says - cannot save changes, file cannot be modified, changes not saved! I have root and I've mounted / and /system as writable! I can edit build.pro without any problem and save the changes, but this file - I can't! How did you edited it and how can I edit it too?
Thank you!

UP!
Moderators, please consider to make this thread sticky / important! Thank you!

did not work for me..
i made the following:
flashed stock recovery from b510
took a fresh 4gb sdcard with dload folder on it..inside this folder was the update.app from the unicom rom..
then turned off device..
then pressed power,vol + & - together and held it 'til the recovery screen with yellow writing appeared..
it started to flash..but on the point where the verlist check begins it tells me "fail"!!!..
so what to do now???
i know this procedure..did it with the b506 rom and it worked..but with the b635 rom it won't work..

Try to flash B706 Chinese EMUI 3.0 new Development edition ROM from the official Huawei web site. If you flash it over the B635 successfully, then you must be able to do this procedure to turn back into international line of ROMs and to B132 4.2 ROM. after that you can flash B510 again. Try this method! I'm pretty sure that it will be possible to flash B706 directly over B635, even than that in the official website it is recommended to update only from B508SP02 official chinese rom. I had success with updating directly to B706 from B512, but if you can't go from B635, try to flash B508SP02 first, than B706 and than downgrade! Should work! Good Luck!

got it..
i just had to flash the b125!!!
so easy..i just flashed the stock recovery of b510..made a force update with the b125 (not the p6 unicom 2.0!!!!)..and now i just upgrade my p6 to b520 via OTA!!!

No. No problems at all. I think just the upgrade took a little while that usual but it flashed like charm over the B512 without any problems! I think the flashing from B508 is just a recommendation, because the B508SP02 is the latest chinese ROM, and this B706 is Chinese developers edition...

That's right! Download the official B706 from Huawei EMUI website, unzip it, put the dload folder in you sdcard and then i recomend to make Local update first. If it doesn't want to update thru local update option in the Update Application, then try with forceful update - press and hold power + volume up + volume down and wait until phone boots into stock recovery mode! The update can only be done with stock recovery! If you're on TWRP, that you must go back to stock!

**** uc browser sucks
I kept to download b508 due to some problem I have to pause it only 36mb was remaining and when I resumed it showed a error was not able to resume the download so I re downloaded the b508 it got downloaded now
So kept to download b706 the same thing happened only 50mb was remaining for the download to complete it showed a error again but this time I did even pause ****
And now someone told me we can update b706 on b512 no need of b508 ****
Today ill download b706 on chrome

Hi,in my Huawei Ascend P6-U06 i installed firmware B513+EMUI 2.3.
I tried to downgrade with this method but it fails when i flash Unicom 2.0 (i follow the instructions:download it..unzip then put UPDATE.app in dload folder of my sdcard).When i flash it,itfails(i have Stock Recovery,never installed TWRP).
Is this method valid also for B513+EMUI2.3?Or maybe i've done something wrong?
Any help is very appreciate..Thanks

Try to flash it forceful with holding all buttons together, or try to copy not only the update.app, but the whole dload folder from the archive. If it's not working, just try to flash B510 or B512 on top of B513 - this should work. After that you can try to downgrade to 4.2 again with the same method!

Cause i'm a newbie,i explain you step by step what i've done:
I follow carefully your instructions(part 1),i try to flash it with local update,but i get message "fail"
After that,in stock recovery,i didn't reboot,but i move to option "apply update from external storage" and after a few seconds i have messages:
-wiping cache (at package request)...
-formatting cache
-cache wipe complete
-install from sd card complete
-cust copying files
-copy cust files successed!
It means that the process has been successful ??? If yes then i proceed to downgrade...
If no,i'll try with your advice to flash B510 or B512 on top of B513...

The process is successful! You must now reboot an go in your android. Now you can copy the other firmware (b510) to your dload folder in sdcard and then try to downgrade! It should work fine!!!

Need help with upgrade path

Hi at all,
could please anybody be so kind and help me to find the correct upgrade path?
I have a P6 with b125 installed. Further I already have twrp 2.8.1.0 installed and achieved root.
Now I would like to go for b708 or 709 but the more articles I read the more procedures I find.
I would do the following: b125 -> b512 --> b708
Is this correct? Or should I add more paths?
And should i do these steps via TWRP or local update?
kind regards
Genesis

This is a very short answer for all my questions
So I would like to explain this sentence what it meant for me and for others who have the same questions.
As I wrote I installed TWRP recovery image. This is a real problem because every time you reboot your phone you enter automatically into recovery.
So you need to flash the stock recovery again. But where to get from? You need to download your current firmare, in my case b125 and have to install "Huawei extractor" . With the help of this tool you can extract the recovery image from the firmware.
So I now installed the stock-recovery image again.
From now you can go on and put firmware b512 into dload and update. When its finshed do it again with target firmware( in my case b708).
After that has finished you can now flash twrp again via fastboot and last but not least you can install the latest kernel via twrp.
Hope I can help somebody

Yes you can
