[Q] P6 Clean install

Hi guys.
I need some help. I updated to KK beta. I then tried to revert back to B125. somehow in the process i formatted everything and now i can not load any version of software. I only have the huawei recovery console. it keeps on telling me "installation aborted" when i try and install software.
Please help.
I do not have any software on the phone. what can i do to fix the problem?

Eject you sdcard, put a ROM in it and flash it through recovery. You have recovery right?

i get a installation aborted error when i try and recover. I have tried b111 b118 b120 and b125. same error. Which folder must the data be in? zipped or unzipped?

On the root of the sdcard, as a zip but flashable. Do you have stock or custom recovery? If it's stock put the update.app file in a folder called dload.Extract the update.app, put only that file in dload and press power and volume up/down all at once for a few seconds until it starts updating. Do not put the ZIP, only the file update.app.

tried and still not working. any other suggestions?

Do you have stock, custom or both recoveries?

Only stock revoery. had twrp installed but install the b118 stock recovery software. now im not able to install any software. phone is clean. no OS.

Well if you have stock recovery the update.app method must work. Do not put the zip in dload, only the update.app file. And repeat the 3 button method until it works.

Tried everything. nothing works

Dont connect usb when installing

He's right, unplug your phone while doing all of the above.

not connected via usb. is there any other way? any other roms to try?

Phone is fixed. thanks for the help

Returning to Original Firmware

Hello,
I have tested a ROM, it worked very well, however I want to return to a original firmware. I have the file but How can I installed since everytime I restart my phone it restart on TWRP mode, how can I make my phone recognize the firmware I want to install?
Thanks,

I would advise B125.
KK Beta is cool, too, but notification-managing apps don't work, and it drains your battery faster

lootjelo,
I have removed the TWRP successfully, however when I try to install firmware B125 it keeps giving me a Fail message.
I have tried updating using configuration->update... etc, and also trying to install it using power+vol up/down method, but keeps me saying Fail.
I have tried B111 and B125, so I believe is not the firmware.

It is on internal storage, however, Im trying to install b125 which i guess is jelly bean and I have 4.4.2 kit kat, could this be the problem?
if is not, then I dont know what could be since dload is on internal storage.

That could be your problem. Rename the dload folder on your external sd to whatever you'd like. Just make sure there's only one dload folder.

I have removed my external copy and I left only my internal copy, the result is the same... FAIL

Actually I think that you need to return to stock recovery and then use the update.app.
To do that you must be familiar with adb and then follow the instructions given at the [INDEX] Club Huawei Meets XDA [ News / Leaks / Mods / ROMS ] .
As it states:
Download Stock_Recovery_B118.zip
Put your device in fastboot mode ( > adb reboot bootloader )
Flash recovery via fastboot ( fastboot flash recovery recovery.img )
Reboot via fastboot ( fastboot reboot )
If you need more help regarding the above procedure read very very carefully this and follow the given steps.
In any case you must bare in mind that since you have KK rom you have changed your recovery and probably this is the reason you cant go back to an original firmware by simple using the update.app.
Good luck

Hmm, that's odd..
Just to make things clear
1. What rom you used before?
2. What recovery are you on now (stock, TWRP, CWM) ?
Also try this. If you have made a nandroid backup before you may follow the instructions in this post from surdu to put TWRP in your p6 and restore it.

Can you check it? Power off and then power on your phone while holding only the volume up (+) button. If it is stock then you shoud see the 3e recovery (if I remember correctly). If not then you haven't the stock recovery.
One more thing. Your phone works ok? I mean that it boots and the it works as it should? Because if you change the recovery, then you probably should have a bootloop with the HYD52ROM_V7 (just a guess, not sure)

It does says 3e recovery.
My phone works very well, I have no problems rebooting, calling, etc, however I´ve noticed I have connectivity issues, I can send mails, photos, MMS, SMS, BUT i cannot receive any photo or open any webpage (only using WiFi), so I want to return to the original firmware.

I am sorry but I ran out of ideas..since you have stock recovery it should work.
If you dont have a nandroid backup I really dont know any other method to tell you besides the update.app.

Yes, I saw that yesterday and put it on SD, but when I select "Install update so sd card", i go to dload folder and it's empty (yes, I checked if the UpdATE.APP is in there)
I installed recovery for b118 first and the boot.img and recovery from b506
so, my phones turns on, I can see the Huawei splashscreen. I can enter recovery as well. and my PC recognizes the phone.
My recovery wont install anything though.
So, can I flash some sort of recovery in this situation? Because I think that flashing the boot.img removed my ROM.

To revert on 4.2.2 flash first that: http://dl.vmall.com/c01l4l4a2y# via local update, after that you can flash 4.2.2 without issues again via local update.

I don't think you can use stock recovery to pick update.app from folder. You have to use 3 button power up method.
Just place update.app in dload folder on external SD card.

From the links i shared before you can get a dload/update.app that you need to put on sd card and update through the stock recovery before you try updating actual stock rom(4.2.2)

The term local update refers to update that you do from working ROM, meaning you are able to go to System updates when ROM is running and choose Local update from SD card.
In this case it has to be done by what's called forced update, 3 button power up method.

I know what you all mean and i tried many times but it wont install anything now! First I got fail, I couldnt choose a updat.app even though it was on sd.
Now it doesnt even load the whole recovery...
And I dont have a rom, when I reboot I am stuck at splash screen.
And the 3 botton method didnt work, after that i selected from sd card but no luck..
is on its way to repair centre right now..

Hello !
Sorry to tell you, but from start you did a wrong step ! First if you was on OmniROM, you must flash ONLY stock recovery for KitKat and not for JB ! From here start all issues in your device !
To avoid any issue , when you use a custom rom based KitKat and you want to downgrade to JB , first you must put your device to Stock Huawei KitKat ( doesn't matter if is beta, B506 or B507 ) ! To install Stock Huawei KitKat - you must to flash stock recovery KitKat - and than flash UPDATE.APP from /dload folder ( where UPDATE.APP is stock firmware Huawei KitKat ) !
Now you should follow the intermediate steps to be able to downgrade to JB ( by installing aditional update.app )
Anyway good luck, and I hope you can solve this issue !
Edit :
You can try this stuff :
First, use your PC with a new microSD to copy UPDATE.APP ( from Huawei KitKat ) in /dload folder !
Go here and take stock recovery for Huawei KitKat ;
Put your microSD already prepared on your device and connect USB cable! Put your device in bootloader mode ( just keep pressing power button and volume down more than 10sec ) - now you should be able to flash stock recovery in your device > fastboot flash recovery recovery.img ; and reboot your device > fastboot reboot ! Right now you can reboot in stock recovery ( adb reboot recovery or using combo key ) and start flash UPDATE.APP !

Hi Guys,
had the same issue today, but thank god i was still able to boot on a bugged omni room to copy file back and forth on my sd card.
But i still cannot find any way back to 4.2...
I tried the steps which surdu_petru write down but i still have the same error message
Checking Module Verlist...
Huawei SD card update fail.
Maybe i made a mistake but these were the steps that i tried:
I`m on the Omni Rom 4.4.2 right now with trwp 2.7.0.0
1. i prepared a microsd with the dload folder of the stock b506 from the huawei site
2. i flashed the stock recovery (B506) from THAT post
3. rebooted the phone and pressed volume plus and minus
4. and then the error message appeard
Maybe someone can explain me step by step how the downgrade works, would like to see the b125 stock on my phone
Thank you!
Sorry for my bad english

You should perform an intermediate step by installing a small update.app before to be able to downgrade to JB ! Solution a few posts above (try to read them all to see what you missed).

u mean that dload from that chinese download site? i tried to flash this with the same method like the stock B506 but it also fails.

Since you have working ROM, try to flash that small update.app with normal update process via System updates-Update from SD card, if 3 button method fails.

what i tried:
1. omnirom 4.4.2 with trwp 2.7.0.0 -> flash kitkat stock recovery -> flash Kitkat b506 -> failed
2. modified b506 custom rom with trwp 2.7.0.0 -> flash kitkat stock recovery -> flash that small update app from this chinese site -> failed
3. modified b506 custom rom with trwp 2.7.0.0 -> flash kitkat stock recovery -> flash stock b125 -> failed
4. omnirom 4.4.2 with trwp 2.7.0.0 -> flash b118 stock recovery -> reboot-> phone keeps vibrating and nothing works until i reflash trwp or kitkat stock
failed = Checking Module Verlist... Huawei SD card update fail

You should try to wipe cache , data and dalvik-cache ( on twrp ) , than flash stock recovery in this way :
Reboot -> Bootloader ;
fastboot flash recovery recovery.img
press combo key to boot on stock recovery ;

Use OTA for manually update from any official KitKat build; don't use fastboot flashable images on existing devices with KitKat bootloader - it will brick the device!

Posted cm12
Just installed the zip version of cm12 on yu. Could not wait for the official ota update. Updated zip using cwm recovery which I had installed while the phone was running on the cm11 kitkat 4.4.4 version.
I understand that since this is just a system update there is no need to change or revert back to the original recovery.
(just a doubt- is it necessary to revert back to original 4.4.4 system stock recovery in case we get the OTA or the OTA will take care of any Custom recovery and will install iteslf?)
Initial boot will take a long time due to the Android Runtime (ART) virtual machine which is the improvisation over the Dalvik Cache. So please be patient for all the 122 apps to get registered in by ART. I had tried the ART while on cm11 4.4.4 (despite of system warning that it might lead to crashes etc... ), even then it took a very long time......
Working absolutely fine. Initial experience is awesome. Will be observing it now for some time. Most other features are similar to the cm11. no more 3g detection errors. Got to explore more....

I owe a lot to this community from which I have taken a lot. I hope I will be able to give back even little that I have got to help others. :good::good:
By zip version i mean the version that can be installed using the phone recovery with out the need of a computer to push the system (i.e. the flashable version). I am not aware what the debuggable version means.

Is the Android version 5.0.x or 5.1?
Has anyone encountered any bugs at all?
To flash through recovery, do I need the OTA version?

YES YOU CAN JUST FOLLOW THIS STEPS
1. Download official CM12s Ota(1st zip in the link).
2. Place the downloaded zip file in the ‘download’ folder on phone’s internal storage.
3. Boot Yureka into Stock Cyanogen recovery - To do so, power off the phone. Then press Volume Up + Volume Down and Power button simultaneously,Onec you boot into recovery do data/ factory reset.
4. Select ‘Apply Update’ > ‘choose from internal storage’ > /0 > Download > and select “cm-12.0-YNG1TAS0W0-tomato-signed.zip” file. The ROM will be flashed and you should be seeing the Android Bot
5. Once installation is over, go to main page and ‘wipe cache partition’
6. Then select Reboot system now
That’s it! Wait for a while as the device boots for the first time with all new and fresh Cyanogen OS 12.
IF you dont get anyhting just revert me back ,or pm will help you.:laugh:

Use OTA for manually update from any KitKat build; don't use fastboot flashable images on existing devices with KitKat bootloader - it'll brick the device!

It just got updated if you flash it on kitkat bootloader, the device will get bricked
Many users have got their device bricked, the warning was too late I flashed it today at 1:50 AM

Hi, You can very well install the .....signed.zip using the CWM recovery as I did.
1. Install the .....signed.zip file and not the ....flashable.zip or the ....bootable.zip files. Only the .....SIGNED.ZIP file either on your phone memory or sdcard
2. Reboot into the recovery mode either by using the advanced reboot option or by pressing the volumeup+down button and power buttons simultaneously and releasing them once you see the Yu logo and phone vibrates.
2. Use the Factory reset command first and then wipe the Cache
3. Navigate to the Install zip and chose the .....SIGNED.zip from either your phone memory or the SD Card as CWM has the option to chose the zip file. and swipe to install it.
4. After successful installation navigate to reboot and swipe to allow the system to restart.
5. Intial boot takes a very long time saying Android is updating. This is because Lollipop uses Android Runtime (ART) by default and not Dalvik Cache as a virtual machine for all apps. So please be patient till all the 122 or so apks are updated by ART. Takes around 10-15minutes.
6. The usual fist time boot stuff.... and then...
7. Enjoy. CM12 it is sweet.

It is android version 5.0.2
To flash through recovery (either CWM or TWRP) use the .....SIGNED.ZIP i.e. the first file in the list and NOT the .flashable.zip or the last one. Only the first one.
I installed the zip through CWM
The only bug I noticed was when you add the Powersaver option tile in the Notification drawer, when in the power saving mode, a notification showing the power save mode got invoked. When I used the same option after rebooting I am not getting it now..
Also all of a sudden a red boundary started to appear at the edges of the screen. So I though I had opted for the screen refresh notification in the Developer options but I had not. Still i could see the red rectangle when the screen refreshed. I had to reboot the system. Now fine.

G8 Stuck in twrp loop

This is the first time I've ever done this, but I just hated the UI on the Huawei G8 (laggy) and decided to try the xda way. PS: knowing that it's easier to help someone when they tell all the details, I am going to post all of it. So sorry for the long post.
First thing I did was try to update to unofficial marshmallow downloaded from here. But it didn't work saying installation failed ... Did some research and found out the device OS is from Iran (I'm from the middle east), so probably the reason why it didn't allow me to install an EU update.
What I did then was unlock bootloader by getting the unlock code from emui website. And then unlocking it from the adb terminal (adb.exe)
Then I loaded TWRP and did a backup.
I forgot to copy SuperSu to the SD card, and when TWRP asked me to root I accepted. So it got stuck on the Huawei logo while booting.
I then did a recovery from TWRP which worked perfectly
I should've just downloaded a new rom and flashed that , but I was like maybe it might allow me to install that update now the phone is unlocked so I tried installing it from the updater ->local update. And that's when the looping into recovery happened.
So I tried to do another recovery from my backup , but again it loaded into TWRP . Which I don't understand since I guess it should load the backed up System. Or is there something telling the device to reload the update from the SD card causing it to crash again ?
UPDATE: I went into file manager and renamed the dload folder to dloadxxx but that didnt help. Then I downloaded the latest TWRP and flashed that, and recovered the backed up system and THAT worked . The restore took longer than with the older TWRP . I have no clue why it worked like this. But maybe this can help someone in the future.
Thanks

Had the same thing. Exept that this happend during OTA update ....
Get a stock ROM of your choice (tested with xxxB130xxx).
Use update extractor to extract boot.img, system.img recovery.img
Wipe all partitions (except external SD Card) with TWRP. Select remove data and confirm. (you said you have backup). This allows a clean install.
Bring phone into fastboot mode (Vol down + power)
Flash bootlader with fastboot
Make Reset
Flash recovery and system
After reboot phone should start up normal.
Let me know if you got stuck somewhere.
Chilli
Edit: Root cause for the problem seems that Hauwei needs stock recovery for some update actions. -> When ever you want to make OTA or dload update flash back to stock recovery before (better flash completely to stock ).

h t t ps://mega.nz/#!P04D2S5Y!Yn2CL5wLC8ISb5AcNR9MTxzhAq3yVH3weG60go5zQCA download this archive, change twrp inside it with the lastest one that surdu_pertu provide.
go twrp wipe all things there
than
using adb "fastboot flash recovery stock.img"
after the first boot phone gonna think a new firmware is being installed just skip it and power off the phone
this will give you a nice start for flashing the Marshmallow from the begining.

Hello Demage,
I would be looking forward to having an Marshmallow image (if it supports my basebands). But Mega says the key is invalid. Can you double check?
Chilli

Thankfully, I managed to fix it.
1- Download Marshmallow G8 stock ROM.
2- Download Huawei update extractor, then extract recovery.img using the previous tool from the stock ROM Update.app file.
3- Go to the bootloader, then flash the extracted recovery.img into recovery.
4- Reboot by the command fastboot reboot.
5- You will get the default loading screen saying the device is reset, then you will be directed to the system welcome screen.
6- You can flash TWRP again, then superSU.
