BQ E4.5: only white screen with bq logo after flashing

guru

0.4.1 gives the same problem: it flashes, reboots twice and stuck in white screen after second boot.

@guru Hmm something has not been flashed if recovery is not there. So we need to get a happy wife as quick as possible. Your flashing stable I guess and with wipe can you try the older installer version and I know we always say this try a different cable just incase. Or maybe the appimage

@guru Sorry just senn youve done that

I booted the device into => FASTBOOT mode ... and when I say in Ubuntu:

# fastboot format cache
Couldn't parse erase-block-size '0x'.
Couldn't parse logical-block-size '0x'.
/usr/lib/android-sdk/platform-tools/mke2fs failed with status 1
mke2fs failed: 1
error: Cannot generate image for cache

@guru remove reinstall adb/fastboot?

@Lakotaubp I reinstalle adb and fasboot; result:

# fastboot format cache
Couldn't parse erase-block-size '0x'.
Couldn't parse logical-block-size '0x'.
mke2fs 1.44.1 (24-Mar-2018)

@guru If you are still struggling try posting here as well https://t.me/WelcomePlus see if that gets a quicker resolution. It seems it's a cache issue and I'm pushed on time this morning. Will be back later though. Not sure what is going on here 0.3.2 also worked on my 5

I tried 0.4.1 again, this time with the dev channel and not stable. While running the installer I watched it's log file:

After the last error with the dev channel I removed all .cache/ubports directory (so the installer must re download all files of the image, and was successfully with the 0.4.1 installer.

Thanks for the provided hints. I will update another E4.5 starting again with the 0.4.5 and will report here.

@guru Glad you are getting somewhere still not sure what the change may have been though.
