Downgrade from B506 to B125 failed

I updated to B506 but I dont have Gapps anymore. So I want to downgrade to B125 or B132 but both failed at checking verlist. What can I do.
I am also not able to boot in Fastboot mode with adb and Power + Volume Down. :crying:

You could also flash GApps through TWRP...

(I said that I cant go in Fastboot mode to flash TWRP again.)
OK I am now able to boot in bootloader after much testing I will try it.

I also had the vetlist problem downgrading from b014 to b125. But bootloader still worked. The only thing that worked for me was installing stock recovery jb via bootloader, afterwards a clean install of b014 again via stock recovery. And than I could install b125, also via stock recovery.
In short words:
1. Install stock recovery jb
2. Put (in your case) b506 to sdcard/dload folder
3. Reboot to stock recovery with automatic new installation of b506
4. Put b125 to sdcard/dload
5. Reboot to stock recovery with automatic installation of b125 withoutthe verlist fail.
This is the only way that worked for me from b014 to b125.

Install this Original_Recovery

You have to go back to stock recovery mode, do this using adb.
Then install KK Beta and then B125

Downgrade B506
Hello,
very you please advice!
I downloaded and installed onto your phone p6-U06 Huawei B506-firmware. It works without a problem, I would like to go back to 4.2 but unfortunately downgrade from 4.4 to 4.2 does not work. Shows me that says "huawei sd card update fail".
Can you please advise what should I do with this?
Thanks

Look.
1-Firstly With the phone download this:
http://dl.vmall.com/c01l4l4a2y# when you are here press the blue booton and the download are in coursing.
2-then, when the download is finished, you go to download folder and extract the .zip archive, and then put the dload o your external sd!
3-after that,you have to turn off the mobile. and the method of the 3 buttons (vol - and vol + power) the recovery will be updated!
4 - after the end of the flashing restarted again, with that before we get We traveled for updated repair fail.
5-'ll be back on the B506, now just stick a stock with dload on the external card and the 3 buttons you flash the stock rom that you have chosen with JB! regards :good:

Thanks ,,,,, it works :good:

I was testing the ART mode on the P6. I replaced the two system files. After some misbehavior of the ROM I wanted to go back to the B125. When doing a factory reset I am stuck on the Startup-Agent when choosing the WLAN(It stops and reverts to Language select -> so loop)
Can I flash this just with TRWP from dload folder on my SD-Card?

3)Install P6 B132 Official zip via Local Update (Extract dload folder in internal storage)

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.

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!

Guide for fastboot is here: http://forum.xda-developers.com/showthread.php?t=2636231
Updates will not work if you extracted directly from internal to sd card. May work if you put the .zip or .rar on your sd card, and then extract it and update the normal way. Not 100% sure about that though! Good luck :fingers-crossed:

When I am in recovery and type adb devices command there aren't any devices showing, so I really have no idea what to do.

Since you have stock recovery maybe you should try updating from a sd card, bevause if had situations when that helps.

I think that B510 I'm 95% sure, oR maby B506
I wanted B634 but now I don't care I just want my phone working

the easiest way is that you reflash the b510..then do a factory reset and then flash through force update method the b634..(when you have the stock recovery - shouldnt matter which Version as long as it is a kitkat one :b510 -b513 or cn version b508 or lower).
after flashing do a factory reset again and then prepare your phone as you like..

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

Here are the steps to successfully downgrade from the unofficial international B708 to B132 international :

This is the only right method to downgrade from B708 to B520 !!!
I tried everything, ROMs, flashing boot.img, recovery.img... nothing, only this is right.
But remember, YUO MUST DO 1. STEP (DOWNLOAD AND INSTALL 706 )
BIGGGGG THANKSSSS !!!
