Downgrading

Sorry guys, I'm new to Android and all of this and i'm in a foreign country so i don't know what to do.
I have a B506 with KitKat, but i want to downgrade to B125, can anyone help me?
I know this question has probably been asked before, but i couldn't find it and i really don't know how to do this, so sorry for being a noob.

Flash through adb stock recovery. Put update.app B125 in dload folder on sdcard and press volume up + volume down + power button until the phone starts updating.

This will not help.
For downgrade from B506 to B125 you will need a middle step. First flash that: https://mega.co.nz/#!9oEHUTiR!uVKEq6PYefO-p4_kJcJpHw2luWZT8QZ5yrnedx4rug4 via stock recovery, after that you will able to flash B125.

Not true. LOL The middle step it's a EMUI ZIP. That's so crazy. Man, don't make people follow your nonsense advice.

alex.79 is right, you can't downgrade directly from B506. That middle step is needed. So the nonsense advice is yours.

No such step needed, you just try to make downloads with that link.
Tested without that step and all went well.

I've downgraded twice but never used that file. What is true (if i remember well) every time, at the firs boot, phone got stuck at logo. Installed the same firmware again and worked. At the second install, i think the script saw that something was not in place and did a factory reset. Maybe a factory reset should be done before downgrading.

Actually, this method works. I did not need the middle step. Just put the download update.app in the sdCard root AND in the dload folder, and then do a stock recovery boot.
In fact, I used the systems local update and got B125 no problem at all.

Before downgrading from KK to JB you have to install this:
http://dl.vmall.com/c01l4l4a2y#
Copy to external sd card to dload folder and use 3 button method to flash. After that you can try JB rom downgrade.

Have you tried doing a factory reset?
Remove your SD card, then boot into recovery via the 3-button method.
Select "Data/factory reset", and "clear cache", then reboot system. You can then insert your SD card again.
Hopefully your phone will boot correctly.

I have sucsh problem too... But no sucsess till now

Ok, then. Just to make sure, you do have the international version of the p6, right? P6-U06?
I just can't understand how nothing is working for you, although we already know that your system IS able to boot with the Chinese firmware, just not completely.

Yes, but what I was asking is if the device you have is the P6-U06.
Anyway, I'm afraid I don't know how else to help you, except to suggest taking it to a service centre.
Or as a last resort, try installing TWRP. There is a guide in the TWRP thread.

Oh sryyyy???my sis
Yeah no one can help me??. I have been searching all of the internet but nothing helps me
I instaled twrp & 3 custom rom but they are like chinnies rom unfortunately.
Again tnx my siiiis

Hi, I had a similar problem last week and here is how I finally could bring my P6 back to life:
1) Install TWRP and wipe system, data and cache
2) Install CM11 ROM and boot with it
3) Put back the B510 stock recovery
4) Install B116 stock rom by putting its Update.app in the dload folder - reboot with the three buttons and it went in recovery and I selected install from external sdcard
5) Boot with this rom, then upgrade to any verstion you like.
I hope this procedure will work for you too.

Can you copy paste here, wich post is ok ??
I want go from CM11 bac to the official emui rom and i dont know how to do this, can you help me ?

To any one having same problem as me. Flash B118 Stock Recovery (via bootloader and fastboot commands) Download P6 Unicom EMUI2.0 from here http://dl.vmall.com/c01l4l4a2y#, unpack and copy dload folder to your memory card and install from "locale update" or force update from recovery by pressing power+volume-volume when phone is off. Next, download B132 International and make update the same way as before (update.app in dload folder). Last step, download B512 official international kitkat and again unzip and use "local update". Just remember to delete old update.app in dload folder. If you experiencing any issues, just do factory reset for fresh install. As my phone is P6-U06, I don't know if it will works for others.
Just please notice: after B132 update I've had message "android process media has stopped" and had to factory reset before update to B512 KK.
so best Idea make a backup of all your important things before you do anything.
I hope it will help to somebody else.

[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!!!
thanks for your help and time!

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!!!

Hello,
I upgrade form b118 to b707 and next to b708 my huawei p6, and I don't see I need b508 to go b707. My mistake.
Now my GPS don't work, I think it don't work earlier, but I don't sure.
I want back to b132 and lock bootloader, but I can not downgrade from b708.

First I try instaled UPDATE.APP which can downgrade from KK to JB, but I have vendorlist fail.
I wiped everyting, instaled recovery and boot.img from b508 and again try instal this downgrade UPDATE but still is vendor list fail.
I instaled custom ROM based on b508 and tried downgrade but again this fail:silly:. Please help, I haven't idea what doing now.

i have downgrade from 708 to B132 as you said the font size is too small and I found the older version is better than the new ones. You have to flash recovery.img and boot.img throught adb procedure which you will find the details in this forum. After that you put the requested image on sd card and flash it
