dumping the Corona v2 nand using SD card reader by GlitchTeam

Recommended Posts

The GlitchTeam with the help of many others (Zhangjiqi007, Zhaojun297…) over at forum.dayton360mods.com push out today a tutorial for dumping the Corona V2 nand (with phison chip). The method use a SD card reader soldered directly to the nand pin.

The only problem with this method is it don’t dump the spare data (each block consists of 32 pages, each page consists of 512bytes user and 16bytes spare, the spare contain block ID, some data specific to the page and a hash of it) which are discarged by the phison eMMC chip. By a fix with another nand (all is explained in their tutorial), you will be able to create a ECC image and launch XeLL.

For now, you will not be able to launch a freeboot image untill the xebuild team update their builder.

For those who want to grab their keys in order to install a xkey or w/e, here is the DL link.

** WARNING ** there is also a little mistake on the first page of the PDF, pin 14 is not named right it should be the one left of that and the wire description below that does not account for u1d1.16 which goes to data0 on the sdcard, pin 7

Thx Swizzy for the info on block layout ;)
