厚机的CECHA~E是NAND的所以基本没有变砖危险
剩下的后续字母都是NOR的，变砖但是可以用E3修NOR（E3没法修NAND）
不过官方出了无机身固件原备份的变砖修复方法了：
需求硬件Requirements are:
1- a Hardware Flasher so you can read/write to the PS3 NOR flash E3之类的NOR刷写器
2- A Dongle with PSgrade payload (any old jailbreak dongle + PSGrade hex will do) used to Enter Factory Service Mode (FSM)PS3的3.41电子狗（可以刷成降级狗的）、PSP之类的（IPOD好像也行）
3- Rogero CEX-3.55 CFW V3.7固件
Recovery Procedure :
0（这点官方没写，首先要拆机，连接E3到主机和PC上，准备好并学会PC端软件操作方法）
1- Dump the current NOR Flash of the bricked PS3 at least 3 times using a hardware flasher (Progskeet / E3 / TEENSY++)用E3之类NOR刷写器读取变砖主机的固件至少3遍（确保没有出错）
2- Verify that it is properly dumped and you have a valid dump by comparing your dumps or following these steps ---> Validating_flash_dumps
验证这3个提取出来的固件如果一致那就行了
3- Patch the dump using Rogero PS3 NOR Auto Patcher ---> PS3_Nor_Dump_Auto_Patcher_v0.01.rar ( Clicked 1834 times )
用自动修复补丁程序修复提取出来的固件（如果三个是一样的话那随便选一个）
3- Flash the Patched Dump back into the PS3 NOR using the Hardware flasher.
再把已经打好补丁的刷回去
4- From this point you can continue as a normal Downgrade Procedure by entering Factory Service Mode using the dongle and Flashing Rogero CEX-3.55 v3.7 from the USB stick.
用3.41电子狗刷成降级狗或者PSP刷降级狗的程序插到PS3进入工厂模式、U盘里放3.55V3.7的固件进行刷写
