Here is the link to my repository where you can find my custom made "short receipt" "OpenWRT 19.07 factory tar file" called "openwrt-ramips-mt7621-ubnt-erx-initramfs-factory.tar"
You can flash it directly over any EdgeOS, and then replacing it by sysupgrading the router again with a usual "OpenWRT official stock image", like the lastest 19.07.2 sysupgrade stock bin file found here :
Kind regards to all.

Hello again.
Here is the detailed procedure to compile an equivalent operational "short receipt" Tar factory image as I have been doing in my previous post.
These things where done under Xubuntu 18.04.2 :
Open a terminal.
Then type the following commands (One of them related to feeds install is doubled because some errors happen on the first launch):
sudo apt-get update
sudo apt-get install subversion g++ zlib1g-dev build-essential git python python3 python3-distutils libncurses5-dev gawk gettext unzip file libssl-dev wget libelf-dev ecj fastjar java-propose-classpath libldap2-dev libcap-dev libidn2-dev liblzma-dev libjansson-dev libpam-dev
git clone https://www.github.com/openwrt/openwrt -b openwrt-19.07
cd openwrt
./scripts/feeds update -a
./scripts/feeds install -a
./scripts/feeds install -a
make menuconfig
Now, from the menuconfig main screen,
Then select Save and accept to save the configuration under the proposed default filename .config and then select Exit until you quit the menuconfig utility and are back to the terminal bash prompt.
From here, enter the following bash commands :
make defconfig
make menuconfig
Go into Global Build Options submenu, and then :
From this screen, enter the submenu Kernel build options and then :
Then select Exit until you back reach the menuconfig main screen, then select Save , it will propose you to save the configuration under the default filename .config , accept it, and then select Exit until you are back to the terminal bash prompt.
Back to the terminal bash prompt, enter the following commands :
make download
make -jXXX
For the last command above please replace XXX by the number of processor cores your computer has. In my case, I used the command make -j8 because I have an 8 cores computer. If you ignore how many cores your microprocessor has, please just type make alone.
The compilation should take about 10 minutes with 8 cores.
Once it is finished, enter the following bash commands :
cd ./bin/targets/ramips/mt7621
ls -al
And you should see the following files :
user@PC:~/openwrt/bin/targets/ramips/mt7621$ ls -al
total 8684

As you can see, there is an openwrt-ramips-mt7621-ubnt-erx-initramfs-factory.tar that was generated. Use this file to update your router from EdgeOS with usual procedures.
Then, update again the router under this temporary OpenWRT 19.07 built with the official stock sysupgrade 19.07.2 bin file from the OpenWRT website, and you're done.
Hello
I have flashed *openwrt-ramips-mt7621-ubnt-erx-initramfs-factory.tar
just realized my erx is SFP model, would this initramfs working?
what I meant I can just continue the sysupgrading with the SFP one?
I was checking the current bin https://downloads.openwrt.org/releases/19.07.3/targets/ramips/mt7621/openwrt-19.07.3-ramips-mt7621-ubnt-erx-sfp-squashfs-sysupgrade.bin
it comes with SFP version too for initramfs below https://downloads.openwrt.org/releases/19.07.3/targets/ramips/mt7621/openwrt-19.07.3-ramips-mt7621-ubnt-erx-sfp-initramfs-kernel.bin
will it become a problem?
Thanks
I would try it, it could work perfectly, as both routers are very similar : Sysupgrade it with the ERX SFP software instead of the ERX bin image.
If it doesn't, if it refuses the ERX SFP bin file, reflash your router with EdgeOS signed image, it takes 5 minutes to do so, it's easy, I can help you if you don't know how to do it.
Then follow the same instructions I wrote for compiling a custom version of ERX tar file, but do it with the ERX SFP configuration instead.
I was thinking about generating the image for the ERX SFP too, but I've been lazy doing it. Still, with the compilation instructions I gave, it will take you half an ahour to do so, it's easy to do.
Please let me know how you went with sysupgrading with the ERX SFP bin sysupgrade file...
Kind regards,
Frederic.
what I did
sysupgrade -F /tmp/openwrt-19.07.3-ramips-mt7621-ubnt-erx-sfp-squashfs-sysupgrade.bin
but came with an image is not match but flash anyway since it was
force upgrade and got stuck with no clue, ssh and luci working perfectly but the WAN won't connect.
and I did button reset, it works now few minutes ago !
My concern about the POE later as the SFP has all ports POE
I am just wondering if the switch is correct? as I have more ports than regular ERX
it would be appreciated If anybody has SFP version can let me know the switch status in OpenWRT
btw
Could you please let me know the steps?
I don't have a backup at all since I was ok if later I have a problem I still can get access with serial console
Thank you
Eganov
Hello.
Will write later on this afternoon a complete procedure to reinstall the latest EdgeOS signed image. Will also provide it on my github repository, it will save you finding it and the procedure on Ubiquiti website. You will need to TFTP from a computer to the Router to reinstall the original image, the procedure will describe how to do this easily.
But then, you should prepare an ERX SFP temporary image factory tar file the same way I did it, just change the board profile with "menuconfig" and choose "ERX SFP" board instead of "ERX board", all other instructions of my procedure should not change.
Going to eat and will be back later on with the procedure.
Kind regards,
Stman
Here is the procedure to reflash the factory Edge OS signed image :
Kind regards,
Thank you for helping me
Have a question if I just TFTP directly (https://downloads.openwrt.org/releases/19.07.3/targets/ramips/mt7621/openwrt-19.07.3-ramips-mt7621-ubnt-erx-sfp-initramfs-kernel.bin)
without going back to edge os
The only problem I don't know how to do nand erase address
do you have an Idea how to do it?
Thanks
Honestly my Router looks fine as I already sysupgrading with the SFP version
I just want to confirm if the kernel for ERX SFP is the same with regular ERX and boot loader as well
I am new to Edgerouter and openwrt
your help is appreciated
I might end-up open the case and see the log from Serial console
and update you soon
It will not work.
In this TFTP recovery mode, it only accepts signed images from ubiquity.
I tried it already.
Yep.
I guess the bootloaders are the same too, and maybe the sysupgrade command update everything except the bootloader.
I understand your concerns.
I shouldn't have pushed you to install an ERX on a ERX SFP and then sysupgrade to ERX SFP image.
I should have motivated you to recompile a clean tar file with my instruction, it only takes 30 minutes to do, and as my instructions are very detailed, you can't fail doing so.
It would be nice to have this ERX SFP factory tar image ready for download for other users that are not used to OpenWRT and publish it as I did, and add a link to it on the OpenWrt website page dedicated to Edge Routers as I did it.
Will do it tonight if I have time.
This is the log I have I obscured Mac and serial number
https://pastebin.com/qTMRjBp4
can you help to check the log is good?
I might need to upgrade the boot loader what is your Idea
Thank you again
It looks ok.
I will try to past my own logs, but I have to open the router to connect to the internal serial port, contrarily to your who has an external connector to gain access to the serial console.
yes but I am at Job site , the machine to compile is limited with low memory and low cpu core
I saw below error on my log
and my board type is E51 instead of E50
which is correct
[ 1.123757] MediaTek Nand driver init, version v2.1 Fix AHB virt2phys error
[ 1.137792] Enable NFI Clock
[ 1.143539] # MTK NAND # : Use HW ECC
[ 1.150849] Device not found, ID: c2da
Can you post your log via dmesg
Thank you
Yep but it's only the linux boot log, not the uboot logs and before... whereas with the console, you get them all sequentially.
Just wondering if you have same error with mine.. Thanks

I am guessing you will have a different one
Hopefully, I will have the correct pair of firmware to get optimum setup
need your idea about my interpretation since I can't make my bin, I am staying in the job site, hard to find the proper machine to compile
Thanks
you might find out your bootloader from your root prompt
root@OpenWrt:/# strings -n 25 /dev/mtdblock0 | grep 'U-Boot'
Thanks
Edit
just found out that my bootloader is current .. (002)
from
Thank you for doing this. Check notes before proceeding.
My steps:
I am yet to test it for stability, I just upgraded it few minutes ago.
Note: As good practice hard reset the router to factory defaults (some pin method at the back) and use static IP for your PC. Also backup the firmware as mentioned in the home page on OpenWRT website. Once you do first upgrade from tar, you will have to switch ports from eth0 to eth1-4 so keep that in mind if you don't see anything.
I needed dns over https/tls so I wanted to go something other than EdgeOS (never got it working properly) and had this around for a long time and wasn't using it so I tried it. I wasn't sure if this would brick it since someone on the github repo opened an issue and said it bricked his and I didn't have any hardware at hand for serial console. Maybe he didn't follow the steps properly. I didn't even do any backups of the firmware which was irresponsible I think. Nonetheless glad I have a working OpenWRT router which at first glance looks really snappy. I tried this previously on 841N and those things were slow and rebooted frequently due to stability issues. Next step would be to setup adblock better firewall rules. I already setup dns over https and it took like 10 seconds which was amazing. I think this is the first real device with OpenWRT I will be using so any recommendations would be helpful. I am only using this for a simple home setup though.
