Motorola put out a Service & Repair Notice (SRN) a while back to remind technicians that not all computers are capable of successfully flashing firmware upgrades when set to the highest communication speed. If you're not sure about your system capabilities, use the default 19.6 kB/s speed. If the program hiccups at the higher speed, a bricked radio may result.

Eric, I am not aware of any means to "clean" the memory. If you send the radio to Motorola's repair depot, it will come back with a brand-new chassis- a new radio in an old case- with the latest firmware installed. Of course, you must have the most recent version of CPS to program it. It is cheaper to replace the innards in a few minutes than to troubleshoot and repair the problem- which might take hours. 73, Eric Lemmon WB6FLY -----Original Message----- From: Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> [mailto:Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> ] On Behalf Of Eric Vincent Sent: Friday, November 13, 2009 12:55 AM To: Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> Subject: RE: [Repeater-Builder] HT750 updating firmware. Hello Eric, Thank you for reply. I used the Non Four Line Display Radio firmware and all of my programming stuff are original from Motorola, RIB, cable and Flash interface Ive start the process and the programming software stop and ask me to do not click on cancel to return to the previous option but I think at this moment it was to late. Right now the radio doesnt power up, completely dead! I have an access to Motorola Online, is it possible to find something to clean the memory and start again? Is it possible to have any program like TK for HT and CDM series? Thanks again to everyone who want to help me with that. 73 Eric VE2VXT /VE7 ________________________________ De : Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> [mailto:Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> ] De la part de Eric Lemmon Envoyé : 12 novembre 2009 10:26 À : Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> Objet : RE: [Repeater-Builder] HT750 updating firmware. Eric, You'd be surprised how often a radio gets bricked during a firmware upgrade. The primary causes are impatience, where the technician disconnects the cables prematurely because he thinks the operation is complete, and the use of incorrect cables or flashing adapters. A radio or laptop battery that dies at the worst possible moment can also be a problem. Since you appear to be savvy about the long wait between the first and second beep signals, I wonder if you might have used the wrong firmware upgrade package. There are two: "Professional Series Portable Firmware R05.14.03 - Four Line Display Radios" and "Professional Series Portable Firmware R05.14.03 - Non Four Line Display Radios" The "Non Four Line" firmware is for HT750 and HT1250 radios only. The "Four Line" firmware is for HT1550 radios. Loading the four-line firmware into an HT750 will brick it. Assuming you have the proper cables and adapters for firmware flashing, I suggest trying to load the correct firmware to see if the radio can be recovered. Otherwise, it's a $275 repair at the depot. Be aware that once the radio is flashed to firmware version R05.14.03, you should use HVN9025W CPS (R06.11.05) or later to program the radio. 73, Eric Lemmon WB6FLY -----Original Message----- From: Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> <mailto:Repeater-Builder%40yahoogroups.com> [mailto:Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> <mailto:Repeater-Builder%40yahoogroups.com> ] On Behalf Of Eric Vincent Sent: Wednesday, November 11, 2009 11:11 PM To: Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> <mailto:Repeater-Builder%40yahoogroups.com> Subject: [Repeater-Builder] HT750 updating firmware. Hello, I've try yesterday to update the firmware on my Motorola HT750 and right now my radio is dead. The original version was R05.09.11 and the wrong one was R05.14.03 Maybe someone in the group have hint for me? Thank you. Eric VE2VXT /VE7
