You can find some vids on yoiutube how to desolder a soic:




(I'm assuming you dont have an hotairstation)

After that you can use this programmer that can read the spi flash: http://autoelectric.cn/ or the flashrom utility with a buspirate or compatible adapter ( http://flashrom.org/Flashrom )

esptool.py --port /dev/ttyUSB0 --baud 115200 read_flash 0x000 524288 backup.bin

When you upload a new firmware, you do not overwrite the bootloader; so there is no possibility of "bricking" an ESP device, as may happen with a mobile phone. In case you do not like the new firmware, you can just download a new AT firmware from the internet and upload it to the device.
