I know a few users that rather stay with stock recovery that use this method a lot for their flashing needs.
Short version :
I finally manage to load TWRP.
Long version :
I first tryed to load cwm, the result was the same. Moreover, even with a load, my phone was kind of messed up. I had to perform a factory reset to get it back. (probably only a factory recovery reset was enough) This is kind of strange behaviour.
Then I tryed to load twrp, It loaded fined (no apparent bug). I can then copy files on sdcard and install these. I then booted CyanogenMod without particular problem.
Finally, I performed a factory reset, and I'm going to keep it that way for now. The reasons are :
- stock rom is imho more stable than CyanogenMod
- I can download a widget for almost all the missing function
- If I have a hardware issue (that the error on CWM suggests), I will be able to return the phone to Google for repair (which is now completely stock)
Thank you for your help
