Unable to erase USER1 partition

I would like to erase the custom changes on my WP76 target, but I always get the failure code “callback status 59399” during the download process.

I’ve tried several ways, but, none with success:

  • DS 5.3.1 : Legato Target Recovery - Option Erase user partition
  • CLI : fwupdate download reset.cwe
  • CLI : swiflash -m “wp76xx” -r
    I used swiflash versions 4.6 and 5.1.

I also tried this in combination with using the TP1 pin or AT!BOOTHOLD to make sure the module is in boot mode.
I did these tests on a Windows 10 Host PC, and also on 2 different Ubuntu 16.04 Hosts.

What could be the root cause of this, and does there exist an alternative way get a WP module with factory defaults? (no fs changes, no root password, …)


Please download fw 12 to module, and then try swiflash in linux pc.

I flashed the R12 image into my targets, and then I was able to erase the USER1 partition without any problem.


Hi, I’m new to using and have the same issue (reset user password on WP7607). How do I flash R12 to the module? (Also to @jyijyi if you could help.)


You can download the R12 one click exe from source.sierrawireless.com


I want to to erase USER1 partition too.

I tried the following procedure with enabling TP1.

No.1: download fw 12 to module (on Window)
method1: the R13 one click exe
method2: “fdt2.exe” with .spk file

No.2: swiflash -m “wp76xx” -r (on Linux)

The result No.1 and No.2 were like that,
the outcome of method1 execution was the following messages displayed and not executed.

FDT version : 1.0.1902.1
Awaiting adapter …
Enabling selective suspend …
Firmware download failed.
Primary error code: 14 - No MBN adapter available.
Secondary error code: 0 - Not applicable.
Device error code: 0x0 - Unknown device error code.

the outcome of method2 execution didn’t finish correctly, when
“Awaiting adapter” message appeared. I had no choice but to stop the process.

C:\Users\tanoue-kenta\Desktop\FW>fdt2.exe -f WP76xx_Release13.3_DOCOMO.spk
FDT version: 1.0.1806.0

I wanted to finish erasing USER1 partition, however, I couldn’t, when the message(Downloading the firmware) appeared and the Linux OS tried to execute the process.

tanoue@feadmin-FMVDK3F061:~$ swiflash -m “wp76xx” -r -p /dev/serial/by-path/pci-0000:00:1d.0-usb-0:1.6:1.0-port0

I am a a loss , because I have no solutions to handle the problems.
Please give me some advice.


is it because you change the status of TP1 and it will not boot up?
Also please downgrade to R12, not R13.

Hi, jyijyi.

Thank you for your help.

The state of TP1 must be “Enable”, because when I checked Device Manager of my computer(Windows), I found Sierra Wireless DM Port.

After I executed method1 and method2 I had mentioned by using R12 FW, the results didn’t change at all.

if you enable TP1, it will always stay at DM only mode.
That is why you always see:
“Awaiting adapter” message appeared. I had no choice but to stop the process.

I tell you some background.
My application hides DM port when the app starts in my system.
Moreover, my application causes reset because of some bug.

Therefore, I turned TP1 to Enable downloading FW12 to module.

Is it neccessary to change the state of TP1 somewhere?

you can give a try to set the TP1 in normal position.
BTW, what is the current FW on your module?
I saw you doing this:

fdt2.exe -f WP76xx_Release13.3_DOCOMO.spk

you can give a try to set the TP1 in normal position.
I could downgrade R12 FW using WP76xx_Release12_GENERIC_GCF.spk

Therefore, the current FW on my module seems to be the R12 GENERIC.

Keeping the TP1 in normal position, I executed swiflash -m “wp76xx” -r successfully.

Thank you.
