I need help with my ps3 !! It is CECH-2004A . I was on rebug 4.84.2 REX . I tried to put stage2.cex and stage2.dex on dev_flash/rebug/cobra (i kept backup of the original files) from cobra 8.3 that I found here on github on one link,. I was trying to update to cobra 8,3...Now my ps3 is not showing any screen after restart. It don't boot on safe mode. I tried booting in safe mode but no success. It must be bricked. I made a mistake and now I am sad and anxious. I have an older nor dump from older rebug cfw I don't know if that helps. I don't have eid root key in order to take backup of my games and saves on hdd. Is it a fix possible ? Will i loose all my files on the hdd ? I am worried very much because it is the first time after years. Sorry if that has been answered before here. Can it be saved with a hardware flasher from an expert technician ? Please help me !!! :(

Have you tried formatting the HDD on your computer, and then reinstall Rebug REX from scratch? Without root key you can't access the data on the drive, but after a format you should be able to reinstall CFW.

If you have enough space, you could do a drive image backup first, then format, reinstall CFW, then get the root key, and that would let you read the drive image later.

Thanks for the reply. No I haven't tried that my friend. If i loose my data and ps3 to be alive again I don't mind. How to do an image backup and format on the pc of the ps3 hdd ? I can lend an external 2.5" hdd case to plug into usb. Will it work ? I am worry because ps3 is not show anything on the screen. I tried AV composite output, hdmi but nothing. When I push the power button it turns on green but does not do anything. I have a question. This fault with dev_flash stage2.cex and stage2.dex files has to do with hdd, i mean a hdd related fault or it is in the nor memory so it must be flashed again with hardware flasher ? Thank you very much
 
if you want your data back, a little hacky way would be, using spare hdd and reinstall CFW. then get rootkey. now connect your softbricked hdd to PC (do not initialize by Windows) and use the modified hdd_reader from me. it will give you the exact offset and size of dev_flash. now open hexeditor and open drive in raw mode. go to offset and overwrite devflash block. if you now put it in PS3, it will just ask for fw reinstallation

Thanks for the reply. So this problem it's a soft bricked hdd and with another hdd it will be fixed but I will loose my files ? Also can the soft bricked hdd be I formated it on the pc and then insert it on ps3 to install fw again ? Also I don't have experience with that on the pc side with hdd reader hex offsets etc..Also Can you tell me or p.m. me in detail for the offsets part etc and what to do for not loosing my files if it is not much ? Thank you very much my friend.

you won't loose any files this way

you can format it the drive, but my post was about saving all the data and just replace devflash. you could also replace the devflash block with a valid new one, if you install CFW on 2nd spare hdd and dump it with hexeditor

if you have dumped your rootkey with 2nd spare hdd, you can get back to me and I will guide you through

edit
you only need the information for the start offset of devflash, like in this example

you have to use a hexeditor and open the bricked drive in raw mode, which will not do any harm to your drive. then you go to the offset of your devflash block and overwrite it, either with zeroes or a new valid devflash block

lol, exdata is in home dir not in flash :oops:

Thank you my friend. I will lend a spare hdd from a friend. When I have the hdd I let you know. I hope the problem to be a soft bricked hdd and not something more serious or something that requires hardware flasher. For Berion post, I don't have linux so I don't know much of it and I don't want to do something that will be unreversable

On NAND models it is inside eFlash region. On NOR models, on user partition.

But this area is encrypted twice. When user will write it by zeroes it will literally kill this sub-partition. What benefit will be with it as PS3 will force format? Because it still needed for the system to boot with proper FAT16 there. I don't get it. On Linux You can normally access there from any file manager with read/write permission.

If you don't care about the data, just take the hard drive, connect it to a computer and format it. Then put the disk back on the console, and reinstall the firmware when asked.

that doesn't matter if you overwrite it, cause PS3 will just ask for reinstallation, or you can overwrite it with a valid encrypted block dumped from another drive. I have done this several times and it was the reason I have modified hddreader, to show exact offsets

background
I have reencrypted my whole 1TB to another PS3, using ps3encdec, which is broken on fat nors and does not encrypt vflash correctly but the hdd drive itself. I then just have overwritten devflash block in hexeditor and then reinstalled firmware. all my hdd files were intact in the end. I even have overwritten devflash block with a fresh installed devflash block from another hdd, which also has worked fine

lol, but I am using Server 08 and love to save resources
 
So I installed a spare hdd and installed cfw rebug 4.84.2, I made 5 nor dumps just in case, and I got eid_root_key with rebug toolbox and I copied it to usb. I have a usb hdd case for plugging the hdd on usb. Now what do I do from there ?

P.S.
So as it seems it was a hdd brick, and with another hdd It showed me the screen for formatting the disk and install the fw.
