Orbi RBR50 seems stuck in boot loop

[tgenty]

Hi,

After my orbi performance dropped, I restarted the router hopping it will fix it. However it doesnt fully restart now. The power led is solid green and the ring is solid white for like 20 seconds then shutdowns for 8 seconds and comes back white for 20 secs and keeps looping, like it keeps rebooting itself

I tried different power outlets and my satelitte AC adapter, no effect.

I tried to hard reset, still the same.

I tried to flash a firmware with tftp, it remains the same. I tried the lastest firmware and some older ones with no success.

I run into the same kind of issue a few months back but I fixed it with the firmware flash with tftp. This time I can't get it restarting. Any suggestion?

Thanks,

So it won't come to ready even after the TFTP and the RBR disconnected from the ISP modem/ONT? 

[tgenty]

That's right. Only the laptop is connected with a cable .

[FURRYe38]

And pressing the reset button for 15 seconds doesn't stop this? 

Try this method of TFTP as last resort:

https://kb.netgear.com/000059634/How-to-upload-firmware-to-a-NETGEAR-router-using-Windows-TFTP
Need to press the reset button for 30 seconds then release, then it send to PUT the command and upload the FW. 
I had a problem on a Windows 10 PC where this didn't work to use TFTP, so I switched to a WIndows 7 PC and the TFTP worked.

IF this doesn't stop the problem, then I presume the RBR is bad and needs to be replaced.

I've already tried the tftp method described in the link. I tried the NG tftp app too and the tftp transfer (put) seems to work just fine. Also, I've have already used the method successfully in the past, so I guess I'm doing it correctly.
The router for 1 year old in april, so not under warranty any more. I should have returned it the first time I had to use the tftp method to recover a failure. It's a shame for an equipment that expensive...

Thanks for your suggestions anyway.

[FURRYe38]

At least you tried. 

Good Luck. 

[tgenty]

So I guess that expensive router will go to the trash after only one year of service.

And over the top, I discovered that there is no support from Netgear. I guess I know what brand to avoid for my next wifi mesh system

[tgenty]

Well I can't just give up on it yet.

So I've opened the router, found the serial pin on the motherboard and bought a USB-serial cable. Now I can access to the bootloader console but I lack knowledge on this.

I managed to confirmed that firmware upload with tftp works well. However everytime it boots, it ends up with a "data abord" followed by a reset.
Here are the logs of the tftp upload, firmware V2.5.1.32 (I've removed most of the dot while receiving the firmware for clarity)

I executed the bootcmd manually and I've confirmed that the "data abord" is issued by the "bootm 0x84000000".

Any help would be appreciated.

This isn't good:

"NAND: Nand Flash error. Status = 64
ONFI Read id cmd failed
ONFI probe failed
SF NAND unsupported id:ff:ff:ff:ffSF: Unsupported manufacturer ff
ipq_spi: SPI Flash not found"

No sure if this is a hard or software failure. Not sure if this can be fixed and the user level or not. Something to ask a NG forum moderator about. 

SInce Orbi base code is based on Caos Calmer, a derivative of DD-WRT, someting you might post about in one of there forums as well. Seen others work down at that level on there FW. 

BTW, how did you open the RBR outter case? 

[tgenty]

I think the NAND error is normal because the orbi doesnt have NAND flash but 4Gb eMMC.

The "data abord" happens whatever version of the firmware I flash so I though the issue might be with the eMMC and the data gets corrupted, but the function to check the DNI image seems to be just fine.

Anyway I'll look at DD-WRT if I can get some help with that, thanks

To open the outter case, you have to remove the sticker at the back, around the ethernet port etc. Then remove the screws that were hidden behind and slide the 2 parts apart (top to bottom). Removing the rubbers at the bottom might help 😉

Strange thing, I tried to start a new topic (twice) with the u-boot issue but it seems it is not visible in the forum. I can see it in my subscriptions but I can't find it with a search and if open the URL to the post when I'm not connected I get a page not found error. If I click on it from my subscription, the reply buttons are disabled. Odd isn't it?

[FURRYe38]

Thanks for the info. 

Good Luck.

Any chance you could share info on the serial console mod?  

I have an RBR50 with damaged firmware and I'm trying to find a way to force it into the TFTP recovery process.  Maybe this would help?

UPDATE: Google to the rescue:

Just curious, did you ever solve?  I have the exact same issue.

I can start nmrp to advertise and laptop shows file is trying to load after starting nmrp on console, then console says nmrp server stopped or failed.   Laptop then times out. They are communicating, but can't get an image to upload.

I solved *my* bricked RBR50 using the serial console....  there's a separate thread about it.

I'd be interested to see how you did it with the console because I've never fixed mine. But when I hit your link I get an 'invalid parameter' error

--- updated ---

I found your thread with the search engine. Unfortunatly I don't have the same issue that you did, the model Id matches between my board and the firmware and the firmware can be flashed. It just doesn't boot correctly...

[brichter1978]

Well I fixed mine after 10 hours or so.  

I ended up booting unit and pressing space from console to stop boot.   Manually set IP to 192.168.1.250.

Had ethernet cable with laptop IP at 192.168.1.5 plugged in direct.

Ran this command on laptop and noticed any time I had this command on the router would be pingable. Chnage both -t ans -T to 90000 to give me more time as pingable.

nmrpflash -v -i net19 -f c:\NG\firmware.img -t 10000 -T 10000 -A 192.168.1.5 -a 192.168.1.250

While router was pingable I ran the TFTP and flashed latest RBS40 FW.

        Used TFTPd64, also worked with TFTP2.

Then noticed to error below as mentioned in post on link below.   Used manual commands and that allowed a good flash.  Reboot took FOREVER, but you could see all the action happening on the console. Plugged into my router and within 2-3 minutes it was in the web GUI.  No reprogramming or syncing.

HW ID on board:
HW ID on image: 29765515+0+4096+512+2x2+2x2+2x2
Firmware Image HW ID do not match Board HW ID
Board HW ID mismatch,it is forbidden to be written to flash!!

After this I did a set on Mac and then did a Saveenv to memory.

Here is link that was broken posted by other.  This link helped me resolve.

Sorry... looks like the editor messed up the link in the IURL somehow.  If you cut and paste the displated text it works, but if you click on the link it has some bogus extra characters on the end.

If you have the router in the uboot console then there are a bunch of commands for testing various bits of hardware.  And you can see much more of the logging when the system is booting, so perhaps you may see a relevant error message.  But if the firrmware image looks to be correct then I dojn't know what else to suggest.

Hoping this helps.  Also note the ans was a typo in NMRP command above.

Came here and created account just to say thank you! Reset button would just not work to upload the firmare that was botched by the automatic update process. But, serial port trick, following your instructions, unbricked the satelite and saved hundreds of dollars in the process.

Some minor details: While I was able to successfully login using serial port, I couldn't figure how to assign a static IP and tftp server would not start without it. Luckily a quick reboot and interrupting boot process, enabled IP address assignment somehow and TFTP server started like a charm and then followed your steps for HW and Model id configuration, save state was not needed in either case.

Thank you again.

This is the last netgear product I'll purchase.

[iScream]

Same here, so frustrating!

 

[FURRYe38]

Try this?

https://kb.netgear.com/000059634/How-to-upload-firmware-to-a-NETGEAR-router-using-Windows-TFTP
Need to press the reset button for 30 seconds then release, then it send to PUT the command and upload the FW. 

IF this fails then the RBR needs to be replaced.
