If you did a backup with twrp you should have your old oeminfo and can go back to L09, If you got test-keys that means you had a branded phone and i would only recommend using the l29.
Other way is to load a l09-rom: http://pro-teammt.ru/firmware-database/?firmware_model=vtr-l09c432&firmware_page=0
Simply replace the 3 files in the hwota folder with the new ones and be sure you rename them to orginalname, otherwise the script won´t find the files.
Thenuse the script and rebrand to l09.

But you have no advantage of using the l09. Huawei versions differ from device to device. If you have and B164 on the l29 right now, it doesn´t automatically mean that for instance a B175 on the l09 is newer. You mostly have to look on the release date to compare.
Still no luck yet getting the Simcard recognised. Though, funny thing, I'm probably the only one on the planet that has a dual-sim L09 :silly:

Thank you for the link. He sure has something fishy going on.
Mine didn't have the 2nd simcard slot available in the About Phone when it came out of the box. That only appeared after having flashed a L29 rom on it and rebranding it back to a L09.

I am at the point where I can deduct my backed up oeminfo to be at fault, as I have also flashed other L09 oeminfo's too with the same outcome: dual Sim activated but the simcard is not recognized in either slot.

Sadly, there's no instructions around how to revert back to L09 properly, so maybe I am missing a step somewhere??

Depending on certain factors rebranding to L09C432 may not work. However rebranding to L29C636 has worked on all devices so far. If L09 fails to read the sim, try L29, even if your device is L09!

do you simcard contain pin code?

Hello there,
i debranded my VTR-L09 demo p10 with the L29C636 .

Simcards, Fingerprint everything work but in Infos i get wrong version number, only 2gb Ram and 16 GB Rom, and no OTA update in the menu.

I try a factory reset in system or in erecovery a restore or in twrp a complete wipe. But nothing works.

Any Ideas?

General question

First of all thanks for taking the time to write this tutorial, even though it is pretty straight forward, i do not seem to understand why you wrote the same steps twice! i did it once and worked for me! i just wanted to take it out of my chest! :)

Hi, I received my P10 from service (replacement of the motherboard). I had branded firmware but now they install me open europe soft (vtr-l29c432b151). I find on the internet that the newest soft is b164. I search for updates in the phone but I can see the info that I have recent software. What can I do to update to the new soft?

Be patient or install the Firmware Finder to force the update. B171 is also available for C432.

After rebooting the device showed the keypad only but did nothing else.
Long story short, after some tries to make it work again I made a factory reset and now I'm on D188-L29), build NRD90M test-keys, EMUI 3.1, Android 5.1 and the phone is working.

FYI: The phone is still unlocked, stock recovery installed.

Firmware finder no result, HiCare no result, update via dload C432 B130, B150, B164 no success.

Any suggestions?

No idea what the issue was but now it worked for me as well.
Now I'm on C432 and right after the first boot it updated to B171.
That's why I like xda, tons of informations. I should come back more often ;)
