Herewith, I send you new version of SMT-R2000 software, V2.11.00 (2009.04.13), Release notes and ECR.
We expect this verison of software to solve SMT-R2000 boot failure by Flashmemory failure and default configuration file.
It is why we could finally reproduce Flashmemory failure issue at the lab and fixed.

Caution1) 
Due to the changes, you have to keep in mind the followings before the software upgrade 
1. V2.08, V2.09 or V2.10 -> V2.11:  It's okay 
2. V1.00~V2.07 -> V2.10 (By Web)
    The existing DB will be defaulted. To avoid it, you have to follow the below procedure:
       V1.00 ~V2.07 -> upgrader file (Upgrader080119.upgrade.tar) -> V2.08, V2.09 or 2.10 -> 2.11
    1) Upgrade SMT-R2000 software using "Upgrader080119.upgrade.tar" file first via WEB upgrade method
    2) Upgrade SMT-R2000 software to V2.08, 2.09 or V2.10 again.
    3) Finally upgrade SMT-R2000 software to V2.11

Caution2) 
You have to keep in mind the below step in order to the upgrade successfully without any issue. 
If not, there is possibility of the upgrade failure (see the potential issues below). 
In the Web page, you must set the below file like this before upgrading the software.
   - SNMP = DISABLE 
   - CLUSTERING = STOP
   - REBOOT 
   - Now upgrade SMT-R2000 software to V2.11.00 using the attached package. 
 
The potential issues when you upgrade when you do not follow above procedure or settings.
   a) SMT-R2000 operation can become slow because SNMP causes CPU Load in case 802.11h is set.
   b) Boot failure can occurs again in a short time after upgrading software.
       In case QoS is updated via Web page, the configuration file is saved to Flash Memory repeatedly and 
       that cause incorrect writing to Flash Memory during the software upgrade.
