RouterTech Firmware NOTICE
--------------------------

Before doing anything, be sure to FIRST read ALL the HTML documentation 
supplied with this firmware (starting with index.html).

You must ensure: 
[a] that your router is supported, and 
[b] that you have downloaded the correct firmware for your router
[c] that you know whether you should be upgrading with a single firmware image,
    or with separate config + kernel + filesystem images - only single images are
    supported
[d] You would be well advised to download and run the Router Upgrade Checker (RUC)
    and the MTD Calculator, both from the RouterTech website, BEFORE trying to do 
    anything else.
[e] Be sure that you select the firmware with the correct DSP drivers. If you are
    on an ISDN connection, then you must select an "ANNEX B" firmware. Otherwise, 
    do NOT select an AnnexB firmware. A quick way to check whether you require an
    Annex A or Annex B firmware is to check the contents of "/proc/avalanche/avsar_ver"
[f] If your router has an Adam2 bootloader, the router's environment will almost
    certainly be FRAGMENTED. This can cause serious problems with firmware upgrades.
    In such cases, you are well advised to get a serial console cable to use for
    defragmenting the environment BEFORE attempting any firmware upgrade.

IF IN DOUBT, STOP RIGHT NOW!!!

And, DO NOT proceed beyond this point without first reading ALL the supplied
HTML documentation.

A. To upgrade by flashing a single (i.e., combined) image (not suitable for all routers), 
flash ONLY the appropriate RouterTech_xxxx_firmware.upgrade.img file.

Run the RUC (Router Upgrade Checker) and it will tell you whether your router is configured
for single image upgrades or separate image upgrades.

B. With the 1350A wireless firmwares, the upgrade process can take anything from between
5 minutes and 8 minutes. At least 3 minutes of this will be AFTER the progress bar reaches
100%. It is important to WAIT FOR AT LEAST 7 MINUTES before doing anything. If you are 
installing the 1350A AR7WRD firmwares, you'd better go and boil the kettle, have a cup of
tea, and take a little nap while waiting for the firmware upgrade to complete.

C. With the "4mb_flash" firmwares, you must wait for at least 3 minutes after the progress 
bar has reached 100% before doing anything else. See warning "B" above.

D. Please HEED THE WARNING BELOW.


*******************************
******** CRUCIAL WARNING ******
*******************************
**BEFORE* upgrading your firmware, you *MUST* first reset the router to factory defaults,
(select "System->Restore defaults". If you don't heed this warning, your router might 
well become an expensive "brick".

AND,

AFTER upgrading your firmware successfully, you MUST also reset the router again to 
factory defaults, (select "System->Restore defaults"; and then reconfigure it from scratch. 

To start with, ensure that the router's "MODULATION" (from the "Setup->Modem" menu) is 
set to MULTI_MODE. Even if it is already selected, select it again, and click on "Apply".

Check that your router's LEDs are correct. If not, you will need to select the correct
LED file.
