[Verizon Droid Incredible 2] ghagerer:
Hello folks!

I recently repaired an second hand Verizon Droid Incredible 2. It has Android 2.2.1 running and it is seemingly SIM-unlocked, but not rooted. I use it in Germany, got it from an American friend some years ago. It works reasonable well for calling, WiFi, UMTS etc.

But I can't install Android 4.x respectively CyanogenMod 9 or 10 on it, what I need for a development project!

I tried getting S-Off via revolutionary.io, which appears to be mandatory from what I can see on the following guide:

wiki . cyanogenmod. org / w / Install_CM_for_vivow

The process doesn't work for me. The following is what I get from the Bash command line, while my smartphone is hanging in the FASTBOOT USB bootloader screen:

$ sudo ./revolutionary

On the bootloader screen, I can see the following version numbers:

VIVO_W XB SHIP S-ON RL

HBOOT-0.97.0000

RADIO-0.99.01.0225_2

eMMC-boot

Furthermore I read the following guide:

www . androidauthority . com / droid-incredible-2-ics-cyanogenmod-9-cm9-unofficial-69716 /

It recommends rooting the Incredible 2 with ClockworkMod by using the following guide:

theunlockr . com / 2013 / 02 / 20 / how-to-root-the-htc-droid-incredible-2 /

I tried to flash the recovery image to my smartphone by bringing it into the FASTBOOT bootloader and applying the following in the bash terminal:

$ sudo ./fastboot flash recovery recovery-clockwork-5.0.2.0-vivow.img

< waiting for device >

sending 'recovery' (3722 KB)...

OKAY [ 1.161s]

writing 'recovery'...

(bootloader) signature checking...

FAILED (remote: signature verify fail)

finished. total time: 1.639s

As you can see, this does not work either.

From the first guide above I conclude, that I need Gingerbread running on my smartphone, since the guide explicitly says "0.97.0000 (Gingerbread only!)". The problem is, that I can't upgrade my Froyo 2.2.1 to Gingerbread 2.3. When I try to do so via the menu Settings -> Software Update -> Check from within Android it says: Network problem: network not available. But this is not due to connectivity issues, since everything works without a problem (WiFi, GPRS, GSM, really everything). I think the problem is, that I am not within the Verizon network in the US and my Incredible 2 wants its updates only from within this carrier, right? I know I would have to downgrade HBOOT after an update, but how can I update my Android version???

I really spend several days on this topic, I hope there is somebody out there who can help me. Just drop me some hints or ideas with which I can get into the right direction. Thanks in advance!
