![]() I found a document called "How to manually update 3300 ICP Controller's bootloader between U-Boot and Bootrom rev 3.0" published by Mitel. In order to downgrade I need to manually install 8.0 SP3 (my desired load), but in order to do that I need the bootloader to be Bootrom instead of the default U-Boot. So my controller was up, but with the wrong software load…I need to downgrade. I did finally get to this EULA, accepted the terms and followed the basic set up instructions necessary to load the controller. In the Quick Guide for MXeIII Controllers with U-Boot document you will note on page 5, that my situation is best described by “Case #4” which reads “Brand-new disk with 9.0 or later MiVB and active partition #1”. Initially I had difficulty getting a controller with the 9.1 drive to even load, but that difficulty was down to patience (they take a LONG time). I’ve gotten some new MXeIIIs with SSDs directly from Mitel, but only half of the SSDs were MiVB 13.2.0.17 the other half were 9.1.0.96. I'm trying to get my controllers to 8.0 SP3.patch them all for the security cert issue and THEN migrate to 9.I'm doing it this way because the MXeII controllers are live and dispersed around the county I work in, and this way I can get all my hardware updated, software lvl the same across the board, patched completely and THEN I can start the task of migrating to 9. Now, so long as that SSD was preconfigured with MiVB 7.2 (13.2.0.17) this was fine and I could just upgrade bootrom all and call it a day. ![]() In the middle of this replacement (about 40 controllers), Mitel started shipping SSDs with the U-Boot bootloader. I need to replace all of my MXeII controllers with MXeIIIs. I'm sorry, this is going to be long but I wanted to provide as much detail as possible.
