Keep in mind, I'm a Linux user, but just jumping blindly into Android. I have rooted the device and am running these commands with ADB (with TWRP running on the phone) as root.
When I try to run the command parted /dev/block/mmcblk0, and then print out the partition details, I get the following error message:
How can I read the partition in parted, and more importantly, why am I getting this error message?
The thing is, the phone seems to be working just fine, so if there is any damage to the partition table, it does not seem to be affecting phone function in any way.
If it makes a difference, the phone is an HTC One V with firmware tailored for the Cricket wireless company, but I asked this in the general Q&A because I'm assuming this isn't phone specific, but a general Android issue.
