[Q] [HELP] Extracting a Stock ROM for modify it topic

Hello everyone.
I want to create my own Custom ROM. I want to make it based on Stock ROM, but I don't know how to extract it.
I downloaded the firmware from SamMobile, extracted the .tar.md5 file with 7-Zip and got the *.img files.
I read some guides about how to use Android Kitchen but I don't know how to start with the Stock ROM to make my ROM based on it, and then, use the Kitchen.
Sorry for my English.
Thanks in advance.
Greetings!

Extracting internal storage from a non-bootable TF101. topic

Hello, as some of you might have noticed in my previous posts around xda, my tf101 is royally screwed up. I'm stuck in a permanent recovery bootloop, and I can't be saved by my PC. the only concern i have now, is just trying to get the files I had on its internal sdcard. could I somehow put the motherboard into a TF101 with a working USB port, or can I somehow connect a torn USB cable to certain pins on the motherboard to detect it? (my friend once said something about UART connections). I only want to get the files. doing things with software seems out of the question now. hardware tricks might be the only viable option for me... I would really appreciate any kind of answer. whether it's a "that's impossible" answer or otherwise. either way, I'm probably just going to be leaving xda forever. so like I said, does anyone in the vast, knowledge a filled xda community have any ideas?
