If you're currently on a version <= 3.55 there's no need for any hacks. Just get a CFW and install it like you would install any update.Hi everyone, i know i'm few years late on this thread, but i have similar problem.
My PS3 slim CECH-2500 can't install firmware also. Same message appears. Firmware version is 3.40. The difference is, i don't know if it was jailbroken or not, i bought it like that cheap ( someone tried to install firmware and gave up). I didn't try installing CFW, only OFW and HFW, because i don't know what firmware was installed before. When you power console it asks for firmware because someone already did hdd format.
I forgot to mention i tried:
- Different versions of OFW and HFW firmware
- formatting USB drive to FAT16 instead of FAT32
- trying different USB drive, and different port on console
- trying to unplug controller while searching for update file on USB drive
- swapping different HDD drives and formatting them to FAT32 ( all were healthy, only the one that came with console had 34% health so i swapped it for 500gb and later 80 and 40 for testing)
My question is, do i need to do flashing in order to install CFW on 3.40 firmware?
You will eventually want to install the latest and greatest Evilnat 4.90 but some people have reported issues installing it directly on very old firmware. If that's the case then you can try gradually updating. Just make sure that any firmware version >3.55 you install is a CFW. If you accidently install OFW (or HFW) >3.55 you'll have to use jailbreak tools to get it to CFW.
Also - I find it a bit weird that you have 3.40, unless you got new old stock or something. 3.40 is the minimum version for the earliest 25xx units. If you're currently on 3.40 it means your console has never been updated since purchase.
Regarding your issue -
Don't bother with HFW. It's only needed to install HEN on firmware versions >=4.83. You don't need HEN if your console supports full CFW (which it does).
Regarding the USB disk issue - Is the USB disk recognized by the console? If it's formatted properly then it should appear in XMB under the photos / music / videos tabs. If you don't see it then you're probably not formatting it properly. Make sure it's MBR-FAT32. If the drive is using GPT then Windows will keep it GPT even if you reformat it to FAT32. You can use a tool called Rufus to format to MBR if needed.
If the USB disk is recognized then something's wrong with the update file.
- Make sure the directory hierarchy is correct. There should be a directory named PS3 in the root directory. Inside the PS3 directory there should be a subdirectory named UPDATE and inside that there should be the update file itself, named PS3UPDAT.PUP.
- Make sure both the directory names and the update file name are in all caps. File names are case-sensitive in the PS3, contrary to Windows.
- Make sure the file name is PS3UPDAT.PUP and not PS3UPDATE.PUP.
- Check that the firmware file is valid and complete. The best way would be to just compare its MD5 with the one written in the place you've downloaded it from.
- Do not install CFW tagged DEX / D-REX / D-PEX / DECR, as these are intended for debug units.
- Make sure the firmware you're trying to install is not too old - When installing CFW for the first time it cannot be older than the OFW you're currently on. After installing CFW you can use the QA flag to downgrade if you wish, however you can never downgrade to versions lower than the one your PS3 originally shipped with (3.40 in your case).
- If that does not solve the problem, try installing the firmware from recovery mode.
