Hello, I am having an issue with my TL-MR3020 (v1.9). I followed all the directions on [piratebox.cc] to install piratebox on my device. However, after 45 minutes nothing had happened and never once did I see the lights blinking as described, rather only the power and wps leds were lit. I was unable to access Telnet, SSH, or the webui using the Ethernet cable, nor was I able to enter fail-safe mode. Additionally there was no wireless network. So I reflashed stock firmware using serial and tried again. However, I left the serial connected and noticed this:

[1.100000] VFS: Cannot open root device "(null)" or unknown-block(0,0)
[1.100000] Please append a correct "root=" boot option; here are the available partitions:
[1.110000] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

I have managed just to get a vanilla openwrt install (Chaos Calmer) on it which ran fine.

What can I do to get a working installation on my device?

Hi,
please redownload the firmware and retry. It sounds more like the downloaded .bin (firmware) file was not correct or corrupt.

best regards Matthias

Thank you very much for the response Matthias

I went ahead and redownloaded the firmware file along with the accompanying .sha256 file. Using Microsoft's File Checksum Integrity Verifier I ran the following in cmd

fciv openwrt-ar71xx-generic-tl-mr3020-v1-squashfs-factory.bin -sha256

The output was nowhere near the value in the .sha256 file, but I maybe I made an error or it could be that fciv does not support sha256 (It doesn't say anywhere that it does). I should note the previous and new download have the same result, so I imagine there are identical.

I attempted to install the new firmware anyway. Which resulted in the same thing.

Is there maybe another download or someway I can ensure the download is not corrupted?

Hi,
ok, thank you for testing it out again. It sounds to me, that you know what you are doing... that confuses me even more.

fciv can only md5 and sha1. So, I downloaded the file myself, did a sha256 test and created a md5sum:

Use the -md5 option to generate the md5 value for then openwrt file.

I uploaded the files to an alternative download page here: [reshare.bitcave.cc]

Can you send me a copy of the commands you entered? Commands for:
* for reflashing via serial adapter
* executing the firmware rewrite process

The error message from the the kernel sounds like the filesystem is somehow broken. Can you post the whole boot log (serial)?

Strange, very strange.

best regards Matthias

Alright, so I should probably specify that I have been installing Piratebox from windows. I could do it from either Arch or Ubuntu if you think that would make a difference, but I highly doubt it would because I have tried installing regular openwrt from serial and it worked just fine.

And you are correct fciv doesn't support sha256, I should have realized that is why it was not giving me the proper checksum. Anyway I ran the md5 checksum on both the file you provided and the others I downloaded all matched the md5 checksum you provided.

Here are the commands I run to flash over serial:

ok wow. good job.

I compared your kernel output to this example [gist.github.com]

The significant difference is this line

Quote

[ 0.490000] m25p80 spi0.0: unrecognized JEDEC id c84016

Your flash(-partition) is not recognized.

Googling that message gave me

[forums.xilinx.com]
[www.dd-wrt.com]

Which brings me to the point how you power your MR3020... How is your wireing?
I usually only connect TX/RX/GND , but voltage is supplied during normal USB connection. It makes sure the device is getting enough power.
If you are powering via serial, I'll suggest rewiring, using USB and do a tftp reflash.

If that does not help, try to use linux for that... maybe windows (tftpd, or anti virus) is doing strange things with the .bin file :-(

best regards Matthias

My apologies for the delayed response

I power my MR3020 with my computer's USB 3.0 ports I only plug in one of the two male USB plugs on the cable included with the router. I do not power it over serial.

I connect Ground, RX, and TX. Additionally I have a 10k resistor across Vcc and Ground

I attempted again with both USBs plugged into my computer and then again with only one plugged into the included wall adapter. Neither set up seemed to make any difference at all, all setups resulted in the same outcome.

mh. ok, I have no other ideo at this point in time :-(
crap :-(

Hello ronjohnson, hello Matthias,

any news here? My device has exactly the same behaviour, even the LEDs are the same.
I came here by googling the Kernel panic, after several retries and tests.

I could provide complete logs, but they are "nearly exact" the same as ronjohnsons, even the timing is the same (same brick ;/ ).

sorry, forgot to mention: This happened after folowing the PirateBox 1.1 OpenWrt DIY Auto-Installation, too!
[piratebox.cc]

Yes, no news here.
TPLink changed the flash chip, so the driver does not recognize it anymore. Unfortunately, I do not have enough time to do a close investigation on this topic... I already found the relevant kernel lines... but no time to write a patch nor generate an image :-(

Matthias

thanks for the reply Matthias.

So, to be clear for others:
You can unbrick your MR3020 via the tftp-method, see [ediy.com.my]
You have to use the image "openwrt-15.05.1-ar71xx-generic-tl-mr3020-v1-squashfs-factory.bin" from [wiki.openwrt.org]

But you can't manually install piratebox there, because there is no space left :/
I was not able to extend the overlay because I could not access the USB-Stick.

Maybe you could go back to an older and smaller version of OpenWrt ...

Ok, this means that the device ID is supported by the most recent version of OpenWrt, but not in the version PirateBox is based on (Attitude Adjustment).
Unfortunately we can not port PirateBox forward to the next version easily... so I'll look into the code and checkout what is possible.

ok.. seems I made fire.

I created a backport of the needed patch and generated a plain openwrt image file for the mr3020. As I do not have a device with the new flash chip, I need someone to test who has a serial adapter and is able to recover a wrong flashed device for herself.

The image is under the following url [reshare.bitcave.cc] - it does not contain piratebox modifications.. only to test if the image will boot.

If it works, I'll do a pull request against our backport repository and do further processing... of a hotfix release in the next days,

Any feedback appreciated.

Matthias

Hi there, I've been looking for a working image I can use for librarybox v2.1, much the same problem I believe.

I managed to get your image booting on my TL-MR3020(UN) V1.9.

Ok, thanks that helped me.
Can you verify if the failsafe mode is working as expected (not deleting custom changes)?

I am rebuilding the image files for LibraryBox and PirateBox now.

I replaced the image on stable.openwrt.piratebox.de , I'll send the librarybox stuff over their mailing list for testing.

I would appreciate if you can give the MR3020 image a try

[stable.openwrt.piratebox.de]
openwrt-ar71xx-generic-tl-mr3020-v1-squashfs-factory.bin
openwrt-ar71xx-generic-tl-mr3020-v1-squashfs-factory.bin.sha256

after flashing, you will have the automatic installation again.

(this is the patch: [github.com])



Edited 1 time(s). Last edit at 10/27/2017 04:28AM by Matthias.

I was able to trigger failsafe by pressing the flashing WPS button and also with F + Enter, and auto-installation on your updated image completed without error.

Before installation the failsafe would perform factory reset, and after install it will drop to shell. Nice work Matthias I now have a working piratebox, will continue to do more testing on librarybox auto-install but I think we are good at least until TP-Link decides to do any more hardware revisions.

I can provide logs for the installation process if you need it for any further debugging.

Tested LibraryBox 2.1 auto-install, also working well on this new firmware.

Minor correction from my above post: failsafe mode does not cause factory reset on the rebuilt image prior to install, I had my results mixed with plain image. My configuration settings are retained when booting normally.

Jeremy, Thank you so much for supporting me to deliver that patch.
I'll change piratebox.cc asap.

Without your support, that bugfix hasn't made it

Glad I could help, not everyone has the hardware to recover a bricked device so at the very least we've made life a bit easier for those like me who decided to flash it without first doing a little more homework.

I guess this patch should also go up on librarybox.us where I started my project? I'm troubleshooting an issue where the /mnt/usb/LibraryBox/Config/ is not being read/applied at startup, although I think that's got something to do with my customizations and beyond the scope of these forums.

Once I've tested this again on a clean install I think it will be worthwhile sharing the update with LibraryBox builders.

So that means we can now install Piratebox with a fresh TL-MR3020(UN) using [piratebox.cc]
and for our bricked TL-MR3020(UN) we have to go through [blog.khairulazam.net] ?
Is that correct ?
Thank you

Hi,
yes.

How do ronjohnson managed to do a vanilla openwrt install (Chaos Calmer) on it which ran fine ? any link ?

Thank you

edit : well I read the log he posted on August 03, 2017 at 6:09pm and this is not the same problem. I'll try to do something when the strange characters appears.

I changed the baudrate to 128000 as stated here [diystuff.nl] and manage to get the beginning readable.

Got it, I could type tpl and do the tutorial to unbrick it. Then I have done this [librarybox.us] to get Librarybox back. Thank you

Hello. First time trying to get piratebox work pls bare with me. I am having the exact same problem ronjohnson is having. My router is a MR3020v1.9 and when I do the steps provided I get the same kernel panic. I tried installing AA12.09 and same kernel problem, unlike CC15.05.1 which works. Auto_flash or auto installation never worked for me. I also tried tftp. So my question is, is MR3020v1.9 actually compatible with pirate box? If so, are there any other steps i can do to install it successfully? Thanks

Just to add my router is that of the (UN) version. Also, ive tried going back to original tp-link firmware to flash from webui and it still wont work. Ive tried BB14.07, that installs fine. Im on Linux too. Good day!

Found the solution after searching in google “MR3020(UN)” at a google group i found Matthais’ image of AA12.09 working in MR3020(UN). Flashed that and now i am in auto flashing. Thanks for this wonderful program. I wish you all the best!

Hi,
you maybe used an older version of the MR3020 image, which is the reason why it didn't worked.

best regards Matthias
