Hey there,

I recently flashed the breed bootloader on my 3g to use it with the pandora box firmware. It works very well but I want to give the newest OpenWrt a try to see how it performs in comparison.
Unfortunately the openwrt-sysupgrade-bins can't be flashed directly from breed (breed always tells me that the image file is not compatible). So I am wondering how I can achieve to get openwrt on my box. Do I need to tweak the sysupgrade file, or deinstall breed first, or flash it differently??
Any help would be very appreciated.

Here is the mtd layout of m router:

[ root @ PandoraBox_46C1 : /root ]#cat /proc/mtd

dev: size erasesize name

mtd0: 00080000 00020000 "Bootloader"

mtd1: 00040000 00020000 "Config"

mtd2: 00040000 00020000 "Bdata"

mtd3: 00040000 00020000 "Factory"

mtd4: 00040000 00020000 "crash"

mtd5: 00040000 00020000 "crash_syslog"

mtd6: 00040000 00020000 "reserved0"

mtd8: 00200000 00020000 "kernel"

mtd9: 07bc0000 00020000 "ubi"

mtd10: 00040000 00020000 "panic_oops"

Thx

if somebody has the same problem, It was something wrong with the tftp server, finally i didn't do It on Linux, used another pc with w10 and installed pumpkin to create the TFTP server and It worked like a charm.

now a week later, got openwrt installed and was working great until today, started to lose connection, wlan and eth was ok, but the pages wont load, got a txt with the log, for if It helps.

now, i don't eaven have access to Luci, not by SSH, but devices got internet, a real slow internet, strange, but i don't know where to start from, since i don't have access to router.


#61

I have tried to flash openwrt 18.06.01 by ssh, but got bootloop immediately after rebooting.
How am I supposed to make it work?
Thanks!


#62

While I don't have this device myself, quite a lot of OpenWrt users do - so I'd be surprised if this would be a common issue with the release images. This leaves two option to look at first, a bad flash (I'm not familiar about what the mir3g has to offer in this regard, at worst you might have to attach a serial console for debugging and/ or tftp based recovery) or a configuration creating havoc in 18.06, the later you can tackle by attempting a factory reset.


#63

Hey. I want to update my openwrt to latest version with USB 3.0 patch, but i don't have my current image to flash in case of lastest one instability, how can I backup my current setup (i tried to backup kernel and ubi to img and then restore but this bricked my router after couple reboots)? Is there any archive site with older builds or something?

#65

Hi guys. Posted here to say that as I watched this forum and saw quite a lot of issues with this router, I compilled an openwrt-18.06 snapshot with all the latest commits and have been running this device with no issues at all for the last day or so. Before, I compilled a master branch snapshot but ran into problems frequently, either with ac wifi or the internet stopping working. So, I think a 18.06 snapshot build is your safest bet for this one. In openwrt's wiki there is info about the build system installation and usage. Dunno when 18.06.2 will be out.


#66

I have also some problems ( i have compiled snapshots also )

OpenWrt SNAPSHOT r8773-3c04d10483 / LuCI Master (git-18.350.50885-91a73be)
Version du noyau 4.14.88

1 - USB3 speed is same as USB2

2 - With USB3/HDD JMicron JMS578 the HDD is not detected

3 - In WDS mode with one in master and two in slave if i disconnect one slave the other disconnects and I need to unplug and plug the power supply for it to work again


#67

I've had the problem for a while that the Wifi 5GHz hangs up on me. No more clients can connect to it. In the 2.4GHz Wifi there are no problems. Only with a router restart I can solve the problem. It looks like the loss of the network always happens at night. I would not like to switch to the 2.4 network.


#68

USB3.0/HDD JMicron JMS561U is also not detected.
my firmware is OpenWrt 18.06.1 r7258-5eb055306f / LuCI openwrt-18.06 branch (git-18.228.31946-f64b152)


#69

Is it possible to install OpenWrt to the device without opening the case and without having to buy an iOS/Android device?


#70

You could try using an Android emulator.


#72

That is expected behaviour, the AP interface is a slave interface to the STA interface, which is the one deciding over essential radio parameters like e.g. the selected channel. If the STA interface can't be brought up, the AP interface won't be enabled; travelmate may partially alleviate that.


#75

I haven't read this epic thread - in general just enable debug logging in Travelmate and check the logs to see what's going on (logread -e "travelmate").


#77

@tahamsaglam can't see any unusual things so far. Between STA-connections/re-connections you have to reload your (wireless) network setup (incl. a small AP-outage) - in travelmate I'll do the bare minimum (a network reload ubus call, nothing more).

If you really like to start with driver development/optimization, I think that you should start with the sources of hostapd and the OpenWrt related patchsets for that daemon, it's the main "controller" for all AP related things.


#78

@tahamsaglam

If you figure it out, let me know, I would appreciate a possible solution but haven't quote figured it out


#79

Repeating 5G + DFS channels = No Go!
There are bug with hostapd. So also check if your are on DFS channels.

#80

Can anyone help me unbrick my router.

I already have a serial cable connected to the router and I am following the procedure here, which states:

  1. Access serial console (use 3.3v adapter) and terminal emulator such as putty
  2. Flash the kernel0.bin file using option 2 flash using TFTP option in the U-Boot menu.

The bootloader presents these options:

Please choose the operation:
1: Load system code to SDRAM via TFTP.
2: Load system code then write to Flash via TFTP.
3: Boot system code via Flash (default).
4: Entr boot command line interface.
7: Load Boot Loader code then write to Flash via Serial.
9: Load Boot Loader code then write to Flash via TFTP.

However, it jumps straight to option 3 (3: Boot system code via Flash (default).) from the list above. The bootloader also seems restricted and does not allow me to choose other options, like:

1: Load system code to SDRAM via TFTP.

Anyone knows what can be done to boot from TFTP?

Here is a section of my bootloader log:

 ##### The CPU freq = 880 MHZ ####
 estimate memory size =256 Mbytes
#Reset_MT7530
set LAN/WAN LWLLL

Please choose the operation:
   1: Load system code to SDRAM via TFTP.
   2: Load system code then write to Flash via TFTP.
   3: Boot system code via Flash (default).
   4: Entr boot command line interface.
   7: Load Boot Loader code then write to Flash via Serial.
   9: Load Boot Loader code then write to Flash via TFTP.

Yes. I tried longer and 5G AP fails after some hours.
