Mini USB Portable 3G/4G router - rt5350f

Introduction

Mini USB Portable 3G/4G WiFi Hotspot IEEE 802.11b/g/n 150Mbps Wireless Router - search on ebay


This hardware seems to be exactly the same like (firmware is different ):
  • HAME A5 Mini
  • HAME A15
Upgrade with default firmware via WEB interface is not possible. Upgrade from u-boot (tftp) is not  working too  - because of broken ethernet configuration. Upgrade from u-boot via serial (kermit) will end with bricked router too ( verified).

Below you will find the way how to bring new working u-boot and openwrt firmware at once.

Basic device parameters:

  • SoC RT5350
  • MIPS CPU
  • Clock 360 MHz
  • 4 MByte Flash (GD25Q32) 
  • 16 MByte RAM (EM639165TS-6G)
  • USB Host 2.0
  • 10/100 Ethernet switch
  • 802.11n interface
  • I2C
  • Uart
  • Reset button
  • 2 LEDs
  • Micro usb as power source

GPIO description:


  • GPIO0 - Reset Button
  • GPIO1 - I2C_SD
  • GPIO2 - I2C_SCLK
  • GPIO7 - USB Power
  • GPIO12 - USB Root Hub Power
  • GPIO13 - Unknown, but seems to be used in bootloader
  • GPIO17 - Red Power LED
  • GPIO20 - Blue System LED

Bootloader

Default u-boot bootloader is broken - ethernet is not fully initialized, and it seems that it is protected against starting other firmware than oryginal one.
Do not try to upgrade this bootloader from bootloader menu - you will brick your device  !

To load openwrt firmware new bootloader is needed - I am using - uboot128.img taken from JiapengLi

Openwrt firmware

Default firmware cannot accept openwrt images so at the beggining (after u-boot upgrade) we will load minimal openwrt firmware firmware.img .

Upgrade procedure

Verification
Check twice if it is router we are talking about:

  • Take a look on photos of PCB
  • Check MDT structure by call "cat /proc/mtd", has to be like below:
cat /proc/mtd
dev:    size   erasesize  name

mtd2: 00010000 00010000 "Config"
mtd3: 00010000 00010000 "Factory"
mtd4: 00117a6d 00010000 "Kernel"
mtd5: 00298593 00010000 "RootFS"
mtd6: 003b0000 00010000 "Kernel_RootFS"
mtd0: 00400000 00010000 "ALL"
mtd1: 00030000 00010000 "Bootloader" 
Think twice :)

First step

  • Reset router to default settings
  • Connect to router via telnet and login with default user name (admin) and password (admin)
  • Now  you can upgrade router via FTP or USB

Upgrade via FTP 

  • Release memory by commands:  
killall udhcpd
killall dnsmasq
killall nvram_daemon
rmmod ehci_hcd
rmmod ohci_hcd
ifconfig ra0 down
rmmod rt2860v2_ap

  • probably you will be disconnected after last command, so login via telnet again. 
  • Verify free memory by calling free, check if you have more than  3500 free memory 

# free              total         used         free       shared      buffers  Mem:        12884         9180         3704            0          532 Swap:            0            0            0Total:        12884         9180         3704
  •  Resize TMP, and start proftp server
mount -o remount,size=4M tmpfs /tmp
proftpd.sh server 192.168.100.1 192.168.100.1 21 10
proftpd
  • Connect to router via ftp and copy uboot128.img and firmware.img to /tmp directory on router
  • ! Upgrade uboot - be careful, do not reset router during and after this operation !
mtd_write write  /tmp/uboot128.img Bootloader
  • You should see on console 
#Unlocking Bootloader ...
#Writing from /tmp/uboot128.img to Bootloader ...  [w]
  • ! Upgrade firmware - do not reset router during this operation!
mtd_write write /tmp/firmware.img Kernel_RootFS
  • You should see on console  
#Unlocking Kernel_RootFS ...
#Writing from /tmp/firmware.img to Kernel_RootFS ...  [w]
  • Reboot router :), enjoy new u-boot with working ethernet and openwrt firmware. Now you can use standard openwrt upgrade procedure. 
reboot 
  • Router will set IP address to 192.168.100.1 , you can login via telnet 

Upgrade via USB

  • Prepare usb stick, format it with fat filesystem, and copy  uboot128.img and firmware.img 
  • Conect usb stick to router and mount it by:
mount /dev/sda1 /mnt
  • Wait a few seconds and verify  if you see files
ls /mnt 
  • You should see content, do not go further if you do not see files ! 
uboot128.img firmware.img
  • ! Upgrade uboot - be careful, do not reset router during and after this operation !
mtd_write write  /mnt/uboot128.img Bootloader
  • You should see on console 
#Unlocking Bootloader ...
#Writing from /mnt/uboot128.img to Bootloader ...  [w]
  • ! Upgrade firmware - do not reset router during this operation!
mtd_write write /mnt/firmware.img Kernel_RootFS
  • You should see on console  
#Unlocking Kernel_RootFS ...
#Writing from /mnt/firmware.img to Kernel_RootFS ...  [w]
  • Reboot router :), enjoy new u-boot with working ethernet and openwrt firmware. Now you can use standard openwrt upgrade procedure. 
reboot
  • Router will set IP address to 192.168.100.1 , you can login via telnet
 Connect UART

In order to have access to bootloader (u-boot) menu and functions we have to connect serial port to the router board. Pads are quite large so soldering is relatively easy.

Serial port parameters:

  • Speed: 57600
  • Data Bits: 8
  • Parity: None
  • Stop Bits: 1
!   One problem has to be fixed - when you will connect adapter to RX in router and power on system will hangs. To fix it temporary you have first power on router and next quickly connect RX cable.  To fix this issue permamently you have connect  router RX and adapter TX by resistor (470 ohm - 1k ohm).

Solder three thin wires to the router GND, TX, RX and connect:
  • Router GND to adapter GND,
  • Router RX via 470 ohm resistor to adapter TX,
  • Router TX to adapter RX.

Router pads description

To test connection:

  1. Connect USB adapter to PC
  2. Start terminal and connect to port with proper parameters (putty http://www.putty.org/ or TeraTerm Pro http://www.ayera.com/teraterm/ )
  3. Power on router - you shoud see bootloader logs

USB to TTL UART converters

My recomendation is to use:
  • CP2102
  • FT232
  • CH340
CP2102 based adapter

and avoid if possible prolific PL2303 because of unstability ( maybe there are plenty of clones  and prolific is not guilty - hard to say).

Program SPI flash

When you failed with u-boot upgrade you can program SPI flash without desoldering it.
You need to connect thin wires to MISO, MOSI, CLK, CS, VCC and GND. I recomend to desolder VCC pin and lift it little bit, you will solder it again after programming. Disconnecting VCC prevent and distrubances from SoC or other components.

SPI flash pinout
Wires connected to SPI flash,
lifted VCC pin at the right corner soldered after programming.

I have used simple programmer made of


But you can use any SPI programmer which supports GigaDevice GD25Q32 or flash you currently have.

Upgrade RAM

You can upgrade RAM by desoldering SDRAM chip and soldering chip with  32 MB. It is required to have  4M x 16bit x 4 (otherwise you would need to recompile bootloader) taken from old laptop memory PC133 SO-DIMM. It can be by example:

  • Winbond W9825G6JH-6
  • Samsung K4S561632C-TC
  • Samsung K4S561632E
  • Micron  mT48LC16m16A2 
  • EtronTech EM63A165
  • ESMT M12L2561616A
According to Boot strapping description pins: 
  • EPHY_LED3_N 
  • EPHY_LDE2_N
are used to determine SDRAM size:
  • 0,0: 2 MB/8 MB (default) 
  • 0,1: 8 MB/16 MB 
  • 1,0: 16 MB/32 MB, 32 MB*2 
  • 1,1: 32 MB 
In order to set memory to 32MB you have to add 4.7k resistor (or just shorten)

    Hello,
    I need a little help here …
    I purchased the same router and when it came I plugged it to the computer and tried to set it as a wireless client.
    The moment I hit submit button the router died and now the only signs of life are the two red and blue diodes that burn constantly and nothing.
    Do you have any ideas how to bring it back to life?

    Hi,

    you have oryginal firmware ?
    Could you try to connect to it via telnet, what is the result ?

    Hello,

    I found your address in openwrt forum. I hope you can help me a little.
    I also have one of these HAME MPR-A1 clones and want to run openwrt. I have a 32MB Version and I assume that I need to update u-boot.... fine. Which firmware should I use to ensure a proper working, because all currently available images only support 16MB. Yes I'm willing to compile a version by myself, but for this I would need additional help. I hope you can help.
    Did you compile provided version+patch from https://github.com/JiapengLi/OpenWrt-HiLink-HLK-RM04 ?
    Anything else or a different approach?

    The description here says, that the image shall be written via "mtd_write write /mnt/firmware.img Kernel_RootFS". My router does not provide Kernel_RootFS. How can I solve this?

    Hope you can help.

      Hi Martin,


      1. Regarding u-boot, probably ( I do not hav 32M version) you should use https://github.com/JiapengLi/OpenWrt-RT5350/blob/master/u-boot/uboot256.img

      2. Regarding firmware I will release today or tomorrow memory independent images, so you can use them.

      3. I have used path you mentioned + many little changes espetially fixes in packages. Some important for me was broken by default. I have additional scripts to generate many images at once.

      4. Regarding missing Kernel_RootFS, could you send me result of "cat /proc/mtd" ?

      Please give me a hint about writing to Kernel_RootFS. I assume "mtd_write write /mnt/firmware.img Kernel_RootFS" won' work. Any idea?

    5. 3D Makers20 January 2014 at 10:46

      Hi Martin,
      looking on you /proc/mtd
      and assuming that you have 4MB flash !

      I would try "mtd_write write /mnt/firmware.img Kernel"

      Remember to upgrade uboot first (256 version).

      Eventually you will have to say hello to USB2uart adapter and solder three wires.

      BTW. you have plenty of ram, so you do not have to kill processes by killall.

    6. martin4android20 January 2014 at 12:39

      ...I did it. I also assumed to overwrite just Kernel. Even when size does not fit. I flashed your mini.bin and after reboot the system led became red. Wifi seemed to be off. Connecting via cable to 192.168.100.1 works like a charm. Here is the output:

      So thanks for your help! According to "free" it only has access to 16MB RAM. I read somewhere that there is a mis-configuration, that can't be solved without soldering. Probably you must set a fixed size of RAM for image creation.

    Hi,

    Thanks for the tutorial. I was able to flash my router to openwrt successfully. However, afterwards I attempted enable ssh via a passwd command, and now I'm not longer able to access the router.

    I'm still able to ping it at 192.168.100.1. When attempting to telnet back in, I get the expected "login fail" since telnet is now disabled. However, I'm not able to SSH into it.

    I attempted to do a failsafe recovery, but that didn't work either. Not sure why.

    Any ideas what's going on? Thanks

      I am in the same boat - no SSH access - actively refused. I've wired up the serial - that works- I can change the password as many times as I like and I've brought the unit into my own network range - at 192.168.1.110 - so I can ping the unit - but no SSH - so all I have is this shell on serial - can't get any further - how do we get SSH access...

    I do not have access to A15.
    According to information there: https://forum.openwrt.org/viewtopic.php?id=37002&p=24

    Upgrade procedure should be the same like in mentioned mini router.
    One issue is still open - how to download image. I have read that A15 has no ftp server nor Mass Storage support. So maybe you can check if is there in any ftp, tftp server or client or meybe wget is available.

    @Nop & Dimitar

    I have published imagebuilder and scripts used to generate images. So you can take alook what is in images, you can modify scripts and ad own packages. I have not include opkg to save space.

    There you have latest image builder:
    https://code.google.com/p/rcc/source/browse/trunk/projects/rt5350_mini_router/OpenWrt-ImageBuilder-ramips_rt305x-for-linux-x86_64.tar.bz2

    decompress it under ubuntu, run ./generate_all.sh


    To change configuration modify ./image_builder_rt5350.sh and content of "Files" directory.

    In a situation like this (i.e.no telnet ) do you have any recommendations on how I can flash it with an image of my choosing ?

    Heh, i have a version of this router. I can telnet in, but cannot run any commands. The busybox (msh) only has access to 5 or 6 commands. Not even cat or ls works. Any ideas ? ctrl -D just closes the telnet session. Does anyone have an "official" firmware, where Telnet works ?

      Hi,
      I have the same version of router with 10 commands. I soldered UART cable and flashed mini.bin using boot menu (with stock u-boot) for 32Mb version. Now I have OpenWRT :)

    So. Now i have it flashed. I used usb-ttl/kermit to get the boot loader, and then i upgraded via tftp. Perfect. Then i started experimenting with the image builder, but it seem to me, that it creates images for the 16 mb version. Any hints on how to enable the image builder for the 32 mb version ?. Btw my reason for doing this, is a want to make a wireless serial server :-). Basicly combining two of the images in the create file. good work btw

      What im trying to do, is flash an arduino mega, via wifi, and monitor/communicate with it, also over wifi. I have tried ser2net, and it resets every time i send a command to the arduino, and thats why i tried virtualhere, witch does the trick, but cannot flash the arduino mega( works with the regular arduino uno). So my plan is, to use avrdude to flash it, and the virtual here, to communicate with my application ( a lawn mover robot). I have tried compiling openwrt from source, but i seem to be lacking som magic, because the /overlay wont quite work. Then i tryed the image creator again, but got 16mb ram, with is too little. The pieces work seperatly, i just need to get the puzzle complete :-)

      Actually I'v changed password and as stated there telnet is disabled now.
      When I try to connect by SSH, I get connection refused, which means either port is not open in firewall or SSH is not included in firmware (as you have mentioned in comments -> to reduce firmware size).

      So, only option is to use UART, right?

    Hi,

    First of all - thank you very much for your work, i been able to reflash my router to the OpenWRT and make it compatible with my 4G donlge (its using cdc_ethernet). I had to build my own package, see https://gist.github.com/samm-git/0e96a99b1e407132f8fd for the changes. However then i found that package builder is compiled for the 16M version. I had to manually patch mem=16M with mem=32M to see all memory. After patch it works pretty well, i was able to put all interfaces (WWAN from dongle, ethernet and wifi) to the bridge and i got tiny openwrt 4g router.

    It would be great if you can accept my patch, i think i am not only person with such problem (native fw not supporting such devices at all). Also could you please tell how you created this image builder? Any local patches or tweaks?

    Hi,

    I upgraded your versions of uboot and firmware to my mini router, than the usb stop of work and the router stop of the webserver (internal), and no wifi network by default work (no SSID).
    So I connect by telnet and changed the password, and lost the connection with the router.
    I tryed to use uart connection, I did this one time, but I break the layer RX and couldn't use uart any more.
    Now my only option to bring my router back is using SPI programmer.
    Please help me
    If I want to programmer using spi.
    What file image should use?
    uboot? or firmware?
    Could you post a step by step to programmer the Flash using spi ? Considering to clear or erase everything from memory and putting all new.

    I appreciate your help on this matter.

    I just read your review about Mini 4G Router - RT5350F Wireless Router but still I can't rate it as the best wireless router because I guess it will not offer best Wi-Fi range and high speed internet. Well, there are different things to consider before wireless router. If you are looking to buy a new router then you check the market for different products. If you are looking to buy a new wireless router then you should take a look at this list of wireless routers. I bet you will find the best one for your needs.
