Hi all,
First I installed nougat via firmware search (or finder) app. After that I did hard reset and when it prompted me to login to google account I don't get keyboard popup but "Tap to speak" instead.
There is no way to switch it.
Erecovery didn't help because it says something like versions are not the same (I can check it again for real message if needed).
I also tried with recovering from sd card (download firmware to dload folder and then vol +, vol -, power button) and got "incompatible version" or smth similar.
Did anyone have this issue and if did, is there a solution?
Thank you
I never heard of such a problem... That is really strange.
Your best bet is to find a firmware that is flashable via three button method and look if the problem got solved.
If it does not work for whatever reason...
Unlock your bootloader and install TWRP.
Then you can maybe reflash GApps and see if it solves your keyboard issue.
The second method requires a BL unlock code though (not sure if you have it).

Thank you. I'll try wit several firmwares and then flash.
I am just informing that I tried with multiple firmwares and they all failed.
Next is flash.
Had the same problem, skipped connection with my wifi, did the setup and voice search Google keyboard, install it and then connect to my wi-fi via keyboard, did the roll back from Nougat to Marshmallow by flashing b300 update via 3 button method, download stock firmware also flash via 3 button method, that roll back also relocked my bootloader, my device is VNS-L31C185

I have decided to upgrade my Huawei U8800Pro stock ICS 4.0.3 to CyanogenMod 10.2 JB 4.3.
Quickly I realized that this is easily said than done. Tutorials I have found on the Internet are not good. They lead me to brick my phone twice during this process, so I've decided to share my experience with community. Here are step by step instructions:
Prerequisites:
I didn't bother to write any hyper-links, because they will probably be dead by the time you read this. Instead I wrote name of the files you can search in google.
Root_u8800pro.zip containing unlockbootloader_u8800pro.exe
AndroidHandsetUsbDriver_v1.zip containing DriverSetup.exe
gapps-jb-20130813-signed.zip
cm-10.2-20130929-U8800pro-VIDEOPLAYBACK.zip (here the ROM thread: http://forum.xda-developers.com/showthread.php?t=2409681)
recovery6.0.3.3.img (I recomend non touch version)
HUAWEI_U8800P_Android_2.3_V100R001C00B521_Oversea_Normal_05010TXB.zip, containing dload folder (link)
404029_4.0_BasebandCWM.zip
When you have all those in place, you can start with procedure:
Install USB drivers for your phone. Run DriverSetup.exe
Connect your phone to USB and wait to get detected. Then run unlockbootloader_u8800pro.exe (chose first button and wait).
Optionaly download Root Checker from Google Play to see if your phone was rooted. You can skip this step.
Copy dload folder to root of your SD card
Unplug USB cable and turn phone off
Press Volume up + Volume down + Power on at the same time. Hold them till you see that your phone started with firmware update procedure. Wait for procedure to finish. Now you should have stock GB 2.3 rom on your phone.
Turn off your phone
Press Volume up + Volume down + Power on at the same time, and wait till you see pink screen
Connect USB cable and wait till Windows detect your phone and show you image folder. Go to that folder and backup original recovery.img.
Copy recovery6.0.3.3.img to image folder and rename it to recovery.img
Turn off your phone
Press Volume up + Power on at the same time and hold till you see recovery console
Chose factory reset
Chose clear cache
Chose advanced/clear dalvik cache
Flash 404029_4.0_BasebandCWM.zip
Flash cm-10.2-20130929-U8800pro-VIDEOPLAYBACK.zip
Flash gapps-jb-20130813-signed.zip
Reboot your phone
Wait till setup wizard of CynogenMod apears
If all went well you should have CyanogenMod upp and running on your phone.
I'm not responsible If you brick your phone. I did it twice before I finally succeeded :laugh:.
How to unbrick u8800pro:
You can always get back to good old Android 2.3 folowing this procedure:

i'm using u8800 pro.i installed CM10.2.but wifi is not working on my phone and gapps also not working.....pls help.....
I think many of us may not be aware as how to perform local update in honor 7 which has marshmallow installed on it. I have gone through it and understand how it feels when you download an update and while trying to find local update option update app. Its frustrating and discouraging too. But I could find the way to do it on some other site. Its simple and easy. Just see below.
How to Update
Unpack the firmware package on your computer.
Transfer the extracted dload folder to your phone’s microSD card.
Take a backup of your important stuff using Huawei’s native app.
Safely unplug the USB cable and turn your phone off.
Reboot while holding Vol Up + Vol down + Power for a few seconds. Release Power upon vibration.
Once the upgrade starts let go of the volume keys and allow the installation to proceed.
And enjoy
Would you like to thank me......Pl go ahead

On browser it works but when i press add new account(settings) at google nothing happends. at e-mail, exchange it works but not at google option. it doesn.t work at youtube, magazin play, google + etc also. after 3 hours of google.ing the problem is still there. anything else works fine. if you have any ideea i will try it. thanks.
You just bought the phone and did not root/modded right? You should try to do a factory reset, and if it does not work the Google Apps must be damaged. To fix it you have to download the original firmware and update with the dload mode:
-Extract the firmware from the zip (you can find download in the forum)
-Put the file UPADATE.APP in a folder named dload
-Copy the dload folder that contains the firmware to a micro SD and put it in your phone
-Make sure to have enough battery
-Open the dialer and type *#*#2846579#*#*
-Click on ProjectMenu -> Software Upgrade -> SDCard Upgrade
This should install the firmware to your phone.
If it does not work do in this way:
-With the dload folder in the SD card as before, shut down the phone
-While powered off, press Volume -, Volume + and power button all together and it will start the installation

After install oeminfo c432 I can't install b370 so decided to start from original firmware so put update.app on sd card (b130), it install as it should and when it reaches 100% it goes to black screen. I waiting for it to boot up, but it isn't.
The device doesn't react any button press. It's not boot (long press power), not enter recovery (Vol up + power), no fastboot (Vol dwn + power) and no 3 button method.
I try to charge it, but its completly unresponsive.
Any ideas guys?
You cooked your motherboard.
Can i have a slice too?
Let the phone charge for a night and see what happens
Thanks for trying to help!
I left it on chaeger over the night but at morning it won't turn on.
I try another method from this thread:
https://forum.xda-developers.com/hu...hed-black-screen-bip-green-t3485836?nocache=1
but linux doesn't see my device too, so I will use my warranty (this device is only 6 month old) and see what will happen.
cheers
