FAQ:

Q1:What’s the E3 flasher Limited ?  The E3 Flasher Limited is an universal programmer for all NOR flash device. It support PS3 slim console better because E3 flasher limited has 16M NOR flash memory , and with NOR FLASH CLIP you no need any solder for downgrade function.

Q2:How about installation for fat and slim ps3 console ?  It is easy install on all nor flash console because of NOR FLASH CLIP included. you can get installation manufal here.Â

Q3:How about NAND FLASH console ?  We will release a new version E3 FLASHER specially for NAND FLASH console, you will get downgrade and dual boot function easier with our NAND FLASH CLIP .

Q4: How many Harddisk we need? What function with E3 Esata Station ?  As fact, you no need any extra HD because you can take out ps3 internal HD and put into E3 esata station. It will play like internal HD. Every time if you change FW, you will be required fomat and upgrade.  So if you want get more function like dual boot and fast switch FW function, you need prepare another HD for another FW, just like you will get 3.7HD for 3.7FW, 3.55HD for 3.55FW, all will be regards as internet HD. With E3 esata station, the internal HD size can be MAX to 2.5T, compatiable 2.5&3.5' HD with MAX to 3G speed , and also works 4GB+ game well ,this means no need USB HD anymore .

Q5: If we will get problem with PSN if switch to 3.7 ?  Some guy say there has unique ID inside original PS3 NOR FLASH, so it will get problem if you choose another NOR FLASH memory. We don't think so because you can keep original PS3 NOR FLASH with 3.7OFW, so even you connect to PSN, it will find you are original, change nothing ! Sure you can keep 3.55CFW on E3 NOR FLASH.

Q6: Do we need any software and PC ?  No, you no need install any software, no need any PC to operation. You get all function on E3 FLASHER itsself. just press key on E3 FLASHER COVER BOARD and wait few min or few second..

Q7: If PS3 upgrade to new firmware, does E3 FLASHER works again ?  We can't promise but will do best to work and provide to all free, you shoud trust E3DIY team.

Â

Q8:Which version PS3 can downgrade and dual boot ?  We find all FAT console works , most slim console works even include some new slim console which come with 3.56+ original FW. We find 3000X version console can programme correctly but can't downgrade and dual boot, we will do best to work it out and provide to all free.
