[One (M8) Android Development] Mischa42:
Hi Dudes,

I flashed my M8 with ARHD 30.1 last night and want to share my experience so far.

@mike1986: Great work! Thanks!

What I did

- Updated recovery to TWRP 2.8.4.0 (according to release notes my old TWRP 2.8.0.3 did not support Lollipop). Installed via flashboot and .img file.

- Make Nandroid backup with new TWRP 2.8.4.0

- Installed firmware 4.16.1540.8 twice (according to Vomers Guide). See logs below.

- Reboot (ARHD 22.2 started fine).

- Reboot into recovery. It worked fine and I didn't had to flash recovery again (as mentioned in some postings here).

- Wipe cache / dalvik cache using TWRP.

- Flashed ARHD 30.1 and did not wipe within AROMA.

- Reboot into ARHD 30.1 works fine (first time it updated all apps and took about 12 minutes to boot)

I faced the following issues. I know I did a "dirty" flash over ARHD 22.2 and that it is not recommended. Next report posting will be done with clean installation (and maybe with ARHD 30.2 ??) :)

- I had no root access with ES Explorer. SuperSU log said I need to installer SuperSUPro, which I did. Root with ES Explorer still did not work. I cleared all data and cache of ES Explorer and afterwards it worked.

- WiFi does not turn on after mobile was off for a while (over night). The workaround with Bluetooth did not work. I had to disable and enable WiFi and had to select hotspot (did not connect automatically).

- The LTE (4G) speed seems to be a bit slower compared to ARHD 22.2. Maybe the new firmware is not optimized for the Vodafone Germany network, or it is just my subjective feeling?!

- No X button to close all running apps, you need to close each app (issue or new feature of Lollipop?)

Cheers,

Mischa

For those who are interested here are the logs from flashing new firmware.
