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?

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
I did all above you said

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.

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.

Huawei P6-U06 Chinese Rom - HELP!

I got this Huawei from China market, it's P6-U06 and running Chinese B113SP02, I'm looking for a best way to make it International and update to B125>B132>KitKat. Problem is there is no option for local update, only OTA but it is says "device up to date" Also I got bootloader unlocked and TWRP 2.7.0.0 installed from
new and there is no root for a moment.
Please see pictures for more details

I it's actually running a custom ROM because atx is a dev team from china so. It don't look like a fake copy.

Thanks I know it's no fake. The question is how to update to official kitkat if there is no "local update" option. Also I'm not sure where to find a stock recovery to force update.app file.
Recently I've successfully installed JB 4.2.2 and it seems good http://forum.xda-developers.com/showthread.php?t=2570602. I can live with it,
but how to get official kitkat on my device?

Root your phone,download b.513 rom repacked by oxalis and flashed true twrp.
Sent from my HUAWEI P7-L07 using Tapatalk

When you want to use stock recovery than go to TWRP 2.6.3.3 for jelly bean and there should be an stock recovery for B118 this you can flash. After that you can flash the update.app for B132 and from there you can flash B512 which is the newest international firmware, if you want Chinese firmware you can update to B508.

thanks guys I will try both ways and will report

That's weird. I've flashed B118 stock recovery, full wiped and forced update.app but failed, I've tried B125 and B132. Update.app has been placed in my sd memory card /dload/. For now I'm on JB custom rom with stock recovery.
Maybe because I'm on custom rom based on B120, I have no idea

SOLVED
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.

Hi.
Sorry to bump this, but, Osstis, how did you get your bootloader unlocked? Is it necessary to have it unlocked in order install another firmware via local update? Mine is locked, I checked. I'm running a Chinese firmware (B508) and Google Play Store force closes everytime I open it, I've tried almost everything I could find online to get it fixed but nothing works.
I want to install B512 on my P6, too. I understand that I need to install a B1xx firmware first, but I'm not sure if I need to unlock the bootloader to do it. If anyone can shed some light on this it would be greatly appreciated. I rooted my phone through the one-click methods found online, those software say my phone is rooted but the app Root Checker Basic says its not, how can I be sure?. No custom recovery installed.
Thanks.

try to get your phone in bootloader mode via adb (adb reboot bootloader)..
there type "fastboot oem unlock UUUUUUUUUUUUUUUU" (16*U)..
this worked for me (coming from intl b125 locked)..

If you are running B508 then tou should alredy have unlocked bootloader and you can install the B512 without a problem.

Does that make any difference?

no..i dont think so..

then "fastboot oem unlock UUUUUUUUUUUUUUUU"

Isn't "adb reboot bootloader" simply the command to boot into bootloader? That's the first command I entered. If hadn't, I wouldn't have been able to enter "fastboot oem unlock UUUUUUUUUUUUUUUU". Would I? I might be wrong

Different stock recovery only can install certain ROM? I tried B125 already cannot. Any other recommend ROM for me to try? I rmb I flashed a quite latest stock recovery

then try the b510 or the b634..
jb recovery can only install jb rom..so do kk recovery only install kk rom as i know..
if nothing brings success try the unicom rom..

You still have your usb cable plugged in. It will NOT work like that. @taaeem has already mentioned that.
What was the previous firmware that you had installed?
If it was a Chinese firmware, you need to try flashing this file first: https://mega.co.nz/#!8kcVADpB!JKeDlX4WQhmAP3mclNTfIzIjVllw5sMhnrj-3KSpSc4

maybe the sdcard causes this error too..had this with a 16gb fuji card..with a 8gb noname it worked..
and unplug your phone before flashing..as mentioned..

hi miz_pimp, if i do not plug in the usb cable, it will directly go into fail as showed in the picture124 i attached below, I do not rmb what firmware i installed previously, but I did a full wipe, I do not think thr is still firmware inside beside stock recovery.

Have you tried the file that I linked to above?
I think your problem is that you flashed the incorrect recovery version for the firmware you had on your device.
Unless you used TWRP to completely wipe your device before you flashed your stock recovery (which was not at all necessary), then you should still have a firmware on your device.

My device keeps rebooting

Hey guys.
I was in my recovery mode. Suddenly my device rebooted and since then it keeps rebooting. I can't even power it off. some times it get back to stock recovery mode and restart after several seconds.
Any idea how can I fix it or reboot it in bootloader mode ?
I tried vol down and power switch but it does not work.
Holding vol up and down show me usb update mode but I get an error about secure boot or something. And when I want to flash zip files using that stock mode every one of them failed in verification and can't be install.
How can I fix this mess ?

hello.
Try to replace your sdcard by a raw sdcard with only the dload file and the UPDATE.APP of your current version in it. Or your previous version depending what you did earlier.
Hold power and + - volume when the phone reboots. An update should run normaly..
Hope it will help you

Thanks , I created a SDCard with `dload/UPDATE.APP` inside it. But update agent did not recognized it.

Try to put the dload folder with the update.app file, on the internal storage and see if it works like that.

I manage to do it via external sdcard in `dload/UPDATE.APP` now my phone recognize the app file but it fails and returns to sock recovery. I tried B132 and B513. I just see a fail message in ascii art.
Can I recovery my phone ?
Is there any solution to flash a recovery mode or something ?
My bootloader is lock I guess

BTW: Guys! Never ever buy MicroSD Cards at chinese fake markets! I bought a 16GB card and fpr pictures etc its working perfectly. But when I wanted to flash the ROM it came up all the time with above mentioned error messages. After I changed to a legit SD card from everything was working perfectly.

changing the micro SD cards didn't work too, Yeah same error on all ROMs.
Do I have to plug my phone via USB when I want to install the ROM ?

you tried b708

If you can enter fastboot i would suggest an odd way of installing the updates. Go to this page http://forum.xda-developers.com/showthread.php?t=2433454 and download the extractor. With it you can extract the .img files from the update.app file and flash the one by one via fastboot. Just do flash them in the order as their numbers. Report back if it works.

How Can i enter fastboot mode ? I tried Vol down and power but no luck
