Awesome work mate

When on windows i found it easier to copy contents of platform tools and any file to push to system32 folder

then run cmd and use adb from anywhere !

sooo much less typing in general

also i had to set permissions to system folders using root browser (including dump target folder) chmod would not do it for me

Does anyone know how some other methods for getting the names of the partitions?

EDIT:

Another question - using ADB shell, is it possible to dump a partition straight from the phone onto the computers hard drive? My little 2GB sd card isn't coping! Thanks

adb shell can see windows folders as read only file system
maybe on linux ? will test and see

I've successfully dumped an image with a size of 1.8GB, but now i want to create the SDCard-image, but thats up to 25GB i guess! How can i dump this rom direct to my PC? Because i can't save this on my phone, have only 32GB HTC One. Or is there an other option to just dump several folders of that sdcard?

Is it maybe possible to directly write over the OTG to the USB-portable-stick (Size about 32GB)?

For sd backups i usually (i have set folder options to show hidden/system files <in windows>) open the sd on pc mark all items and zip it to my hdd as ie. sdback-260314.zip and if i ever need i can just unzip direct to sd again

(i need all of them, not only pics or messages).

Thanks

Reboot into twrp plug in an external USB stick mount sdcard , mount external USB copy /dev/block/mmcblk1 to you external USB storage. At least that's the file on my phones. I don't own a HTC one but I was able to do this on my DNA

I was able to dump all 34 filesystem partitions by pulling the main header of the block into one massive file. In linux reader it looks cool mount one image and 34 partitions appear. Each partition can be easily exported to their seperate image from there. It took almost 2 hours just to pull the 9gb block. But it was worth it.

So far I've been successful with this method on every rooted device I have. Still have yet to not had any success from a pc. Keeps causing cmd to crash from the huge file transfer. I will have to try from my studio pc. I think 32 gigs of ram will allow cmd to survive the torture.

Enable USB debugging. Plug your phone into pc. Make sure your phone DOES NOT unmount you card as a disk drive Open cmd in your android-SDK platform-tools.

Type..

adb devices
adb shell
su
I'M NOT SURE IF ROOT IS REQUIRED
cat /dev/block/mmcblk1 mmcblk1.raw

Depending on the device folders and names could be different. Defining you SDK platform tools environment path will help

This works on windows 7
Word on linux reader program is good tool to mount the raw nand dumps in windows pc.

Next step is to see of the nand dump can be restored on a dead boot bricked device. I've been looking into several of the small partitions on HTC devices and I keep seeing references to vol buttons, uart and jtag.

I'm new here. Shoot me a thanks if you liked me contribution.
