You can always use the latest RUU and not need to downgrade.

I've got the latest RUU but can't get it to run. I keep getting Error 170, that it could not find my phone. Any assistance would be appreciated.

Also, quick question. I located two different RUUs, filenames below. Which should I be using?

RUU_IncredibleC_Verizon_WWE_1.22.605.0_Radio_1.00. 03.04.06_release_161493_NoDriver
RUU_IncredibleC_Verizon_WWE_1.22.605.2_Radio_1.00. 03.04.06_hboot_0.79_release_161494_NoDriver_0514

Thanks, any help is greatly appreciated.

I'm trying to downgrade to before the OTA update hoping that it might make it easier for me to get root on my Inc. I bought a new PNY 2GB card and copied the PB31IMG.zip file onto the SD card. When I Hboot my phone, it doesn't not recognize the file. I am able to open the file in 7-zip without problems. Re-downloading file produced the same results. The SD card is formatted FAT.

Any suggestions?

EDIT: I reformatted the card to FAT32 and it seems be working now.

Thanks for the info. It was driving me crazy. Now back to rooting again..

I was having the same issue, the hboot wouldn't recognize the zip file. I put in a blank SD card, formatted it to FAT32 instead of FAT, copied the zip file onto the card and went back thru the process and it is now working.

Thanks for the tip!!

Thanks for all your helpful videos.

Total android newbie here (8 days into ownership) and trying to downgrade before the Froyo OTA update. Rooted with unrevoked3. Copied the PB31IMG.zip file onto the SD card. When I Hboot I get something like it's trying but it goes by too fast, ending with 'or wrong length'. Tried downloading from multiple sources with same results. SD card is formatted FAT32.

Phone runs okay, I just want to unroot in anticipation of Verizon's 2.2 rollout.

Suggestions for what to try next?

I haven't seen that issue. Make sure you aren't changing the name to Pb31img.zip. Just name it PB31IMG. Otherwise you end up with a .zip.zip

With Android I have found it easier to have the pc show file extensions so I know what it really is.

[beaubeau]

Thanks Doug. Here is some further data.

-When the phone is booting the message is "No image or wrong length".
-If I reboot normally, I get status messages:
Preparing phone storage
Preparing SD card
Blank SD card

I've attached a screen shot showing the phone attached to my machine and PB31IMG.zip being on the SD card (named HTC SD, during format as FAT32).

What would make the Incredible not see that file on the SD Card?
