GUIDE!!!! How to update to EMUI 9 on C432 L09 and L29

[Blueshell2000]

I've just bought a L29 C432 and this method does not work.
Have tried with USB-memory and a USB-disk.
The file structure looks like this:
dload
--update_sd.zip
CLT-L29_hw_eu
--update_sd_CLT-L29_hw_eu.zip

What software version are you on? It has to be 161 otherwise you can't upgrade from anything below it.

Is there anyway to do this update without a USB otg cable? Can't find one in a shop here and it will take a few days to get one delivered if I buy online. My bootloader is locked.

I try connect my pendrive SanDisc 32gb micro usb through usb C extention and is not working.
I try normal micro usb cable and usb c connector and is connecting perfectly my phone to the computer.
Any idea why my pendrive is not connecting ? I format him exFat but not showng up on my phone...

Just installed and working perfect! enable OEM unlock and USB debbuging in developers options, and also use a OTG compatible cable or device,

I did the same.
But i always get same error

Meanwhile, whenever I click "Developer options", i see USB debugging is passive.
i make it active.
i exit menu.
then i check again, it is again passive..

See if you can get an update to 161 and then repeat the dload process. I guarantee you it will work.

I dont know if its really needed but i enabled with oem unlock and it works, installed perfect, your phone detect the usb drive¿?

Another point for everyone, after just installed Pie i realize some lag in the phone, so i repeat the process again, and boot perfect, more fast everything, i dont know why, but its works

Just flashed successfully few minutes ago!
Thanks thanks thanks!
Just my 2 cents, first try with a sand disk cruzer micro 8gb usb pen failed (2 times), then I tried with another usb pen (unknown brand) an it worked well!
Coming from B161 emui 8 on my P20 pro dual sim no brand C432

Updated to 161, still doesn't work.
Using an older Sandisk Cruzer 16gb drive.
Unfortunately I didn't have any USB-C OTG adapter, instead I'm using a micro-USB OTG adapter with a micro-USB to USB-C adapter.
The phone finds the files and USB drive.
Could this be the issue?

Well, think where on to something here, seems like the Sandisk Cruzer is not compatible

I have a Sandisk cruzer usb and it worked perfectly. I had a USB C OTG cable and not one with a micro USB adapter so this could be causing a problem with the installation

Guess I'll have to wait for the OTA then, or buy a USB-C OTG adapter
Thanks for the help!

Delete the update_sd_CLT-L09_hw_eu from the root because you already have one in the CLT-L09_hw_eu folder

To those who cant update with the OTG method, https://www.huaweiforum.rs/discussion/1196/tutorial-update-na-stable-emui-9#latest

Just translate to your local language, looks easy, and doesnt needed oem unlock, just faking the huawei servers
***
I dont know why but i havent the option in the erecovery to update throught wifi, anyone more?
just:
reboot system
format factory reset
format cache partition
