[One (M7) Android Development] Astarax:
Yes, and i verified the md5 checksums afterwards

It's working now - see Edit 5 :eek:

Edit: After having problems with my win10 pc flashing a new firmware to the HTC, i am using my xps13 with arch now... Flashing a new firmware worked now. Now it shows

instead of a missing number...

Afterwards i flashed the boot.img from the zip file and reuploaded the entire zip from the xps13 to the m7... Tried to install it again and now it seems to hang after the Target:...user/release-keys entry since 5min.. oh and now while I'm writing this, the same error as before :(

Can you recommend a firmware version? Maybe that's the / a problem?

Edit2: I am still able to start the VenomOne 9 Aroma installer

Edit3: It's a new error message:

I'm out of ideas :/

Edit 5: Sry for spamming but i got it now... It's working! :fingers-crossed:

Cleared everything again, cleared the entire data partition, reuploaded the zip files, reflashed the recovery and i could install it... \o/

I'm on M7_UL_GPE_Firmware_6.04.1700.19 for now.

I'm still curious if this is the best one, or if i should use another firmware :)

Many thanks for reading this and for your answers in advance,
