Bon je suis passé en .190
J'ai d'abord cherché le dload 190 et j'ai trouvé ça :
Hi fellows xda'ians, I've made this thread in order to have a clean and updated one with links for latest dload firmware, info, changelog & other guides. I will keep updating this OP with newest dload firmware ONLY for EMUI 10.1. To decompress...

Puis en lisant je vois ça :
How to check for update using eRecovery on EMUI 10:
It doesn't require a cable plugged in and using this method in order to update
WON'T wipe your phone data, it's acting like an normal OTA. In order to acces eRecovery,
Power OFF your device or
Restart it. Press then simultaneously
POWER+VOLUME UP and keep them pressed untill you see Huawei on screen. Release the
POWER button and keep pressing
VOLUME UP untill you are in eRecovery menu, then release button. When in menu, select
Update mode, then select
eRecovery mode then
Update and recover system then
Download update and recover. Connect it to Wi-Fi and it should start the update. If it's still the version you're atm, you can hit
Cancel and then
Restart. If it's a newer version than the one installed, let it download and update. At the end, it will restart to system.
Et les mots clefs important : "
WON'T wipe your phone"
Du coup je l'ai fait et ... Ça marche !!! Je suis en 190 et je n'ai rien perdu. La seule fidd avec un otg c'est que ça téléchargé les 4go de l'image système et pas juste le différentiel
Voilà si ça peut aider quelqu'un un jour
