Unbrick Synology DS918+

Some questions:

Are you sure you're flashing the chip correctly?

Did you remove the chip from the board to flash it? Which programmer are you using?

During boot, are you watching the output on the UART serial port?

Are you sure you're flashing the chip correctly?
Yes. First I've deleted the chip and verify it. Later I wrote the chip and verified with the software itself. Later I've read the chip and save in a file and compare the both files having clear that the bios is the same like I've writed.

the strange is after the first try to boot the NAS If I read the chip, the content always it's different than the wrote before.

Did you remove the chip from the board to flash it? Which programmer are you using?

At the beginning yes because using the CH431 programmer always have problems on verification, but later I've soldered and do it direclty in the mainboard with the software NeoProgrammer_2.2.0.8_from_4pda and AsProgrammer_2.0.3a, both works perfectly.

During boot, are you watching the output on the UART serial port?

During the boot I not see anything on the serial port. Only if I remove the memory ram in that case I see something like "Memory training fail, In a Dead Loop: Acting...". if I plug again the memory then not shows anything.

I've seen in the forum something about this, I need to check it but I'm open to some sugeriments...

I wonder if the system is trying to reflash the bios on boot…

Perhaps your winbond chip itself is bad? They can be found online..

Afternoon guys - just wanted to update you on my adventures as per the above. Had the exact same issue as above, only my DS918 would occasionally boot. Say one time in thirty ish, it would progress from flashing blue light to solid and beep, and then be absolutely fine for weeks at a time! However, the reboot or a power issue killed it again.

I used the CH341 as per above along with a SOIC clip, read the chip twice, extracted the bios.rom from the PAT files (only the ones before 7.1 will open in 7ZIP I think) and followed all of the above. However, no joy when trying to boot, same situation. However, after 3/4 retries, the Winbond chip seemed to go faulty and would have read/write errors.

Decided to roll the dice on a whole £5 worth of replacement Winbond chip, flashed it, then replaced it for my funky one. And just like superchromix, I was blown away that it now is absolutely fine again. Boots just fine every time so far, and it's been rebooted a lot!

So there you go, folks... If you are desparate, replace the Winbond. It's like 5 mins to flash, 2 mins of careful soldering and £5 to try, so give it a go!

Huge thanks to everybody above for their feedback and for basically getting me to this point. Awesome work guys.

Good day everyone,

I managed to flash the chip through your advice. However, I was too quick to flash the chip right away with the bios file from Synology. I didn't think about modifying the file with a hex editor.

Do any of you have the relevant information where to start and end the file?

Thank you very much in advance for your answers.

Sent you a PM

Thanks all, I was able to 'unbrick' my DS218+.

Hi, I just found this post on google. I'm had a DS218+ having same trouble, blinking non-stop after power failure.

Already back up faulty rom and extract a bios.bin from 7.0 pat file.

But having trouble modifying the bios, may I know your steps to fix the bios file?

I tried to unbrick by DS918+ but unsuccessful so far. Good instructions by PH3. I am able to read/write my bios. Then I connected console to see what is going on.

Seems like my NAS hangs right after booting SMP configuration.

Not sure what is causing this. Started happening right after I tried to upgrade to DSM 7.2

                             GNU GRUB  version 2.00

   Press "CTRL-C" for boot menu or it boots automatically in 0s.
  Booting `SYNOLOGY_2'

Hi, I have bricked DS218+ and followed your steps (more or less expect getting exact file size, i have still difference in bytes)
anyways, i cannot get similarity between my ROM file and PAT file (i tried different firmware versions)
would be great if you could share your modified firmware so that i could flash it directly.
in the meantime, I am trying to get it work.
Thanks, Bahodir

get in touch by PM

I just needed to post a big thank you. I was able to unbrick my DS918+. I reflashed the bios and replaced a dead CMOS battery. I could not have done it without the excellent detailed instructions from superchromix & PH3


Steve

Sorry for overdue message: I have managed to get my ds218+ running with the help of this forum and input from members.

I wanted to add some more details so other no-so-experienced users like me can follow instructions mentioned earlier:
- I have replaced CMOS battery with no luck, kept new battery in.
- I have used CH341A Programmer with 1.8 v adapter and SOIC8 Clip. I did not use any soldering as I could easily attach clip to the chip
- I could read/delete/write to the chip with the help of CH341A programmer but I had wrong file to write
- my mistake was using latest firmware from synology website, it is not possible to get ROM from that .pat file. So use 6.* or 7.1* version, not 7.2*
- the .pat file is like archive file that can be extracted with 7zip or similar programs. I have tried several and worked well without issues
- I used HxD hex editor and followed instructions from other members. it was way easy to get exact file size with one of the commands in hex
editor, i just had to give file size and save it.
- my first flash did not work for some reasons and i wanted to connect to serial port to read the outcome but even after several days' trial could not make it work.
- then I read / delete / write my new firmware once again and I let it run for some minutes.... and after couple or more minutes I could hear BEEP.

Cannot thank enough to instructions of superchromix & PH3!

I have working rom file in case someone needs it for DS218+

all the best, Bahodir

Can anyone flash a ds918+ for me I'm having trouble with the technical side of things (I'm not very bright), the unit flashes for 20 seconds the turns off, it was OK until I put a drive in from another ds918+ with a newer version of the dsm firmware, I'd appreciate any help.

Superchronix, do you mind sharing the full 16Mbit bios file?

Send a PM

sent

i was digging in the original ROM file from a DSM 6.2.X and found out that the ROM file contains the actual utility H2OFFT from Insyde which is used by various vendors for bios flashing.
there is clearly visible the ini config file for the utility.
my guess is that the ROM file is an executable containing all these files - utility, config file and bios file - hence the offsets till you find the actual bios file

Superchronix, do you mind sharing the full 16Mbit bios file?

Some additional detail for those who are having difficulty with this.

1. The binary data which needs to be flashed to the bios chip is contained within the bios.rom file, which can be extracted from the Synology .pat file.

2. The bios.rom contains 8MB of binary data which needs to be flashed to the bios chip, plus some additional header and footer bytes. The header and footer are not part of the bios code and must not be flashed to the chip. The actual bios code therefore needs to be extracted from the bios.rom file, manually, using a Hex editor such as HxD.

3. The region to be extracted can be identified by examining the structure of the bios.rom file. For example, search for "IFLASH_BIOSIMG" within the file. The actual bios code starts, in one example, exactly at address 000AD1D0 with the hex value FF, and ends at address 008AD1CF, also with hex value FF.

4. Once you have the 8MB of code from the bios.rom file, add an additional 8MB of zero padding to obtain a 16MB file. Flash this file to the chip.

I hope this helps. The above procedure may vary depending on the specific version of the bios and the NAS model.

here is the report of the mmtool from the original bios chip of DS918+
i personally cannot read it yet but maybe it will help someone in the future

so my DS 918+ is dead even after the bios reflash.
if anyone is going to try this in the future i can confirm that the bios can be read and written from the winbond chip using the clipper that comes with the CH341 programmer
mine having a different problem, i might have a good backup of the DS 918+ original ROM file if anyone is interested...

I don't have the equipment, or skills, to flash a bios chip. I don't know anyone who would be able to do that for me either. I do have people who would be able to remove and replace a chip if I had access to one that had been flashed.

Hi Superchromix,

Could you please share the working BIOS with me?
Thank you in advance.
