In that case, ROM writer equipment is needed. Recovery files for e.

KSU/VVMU Recovery TFTP Server Program 1. Install TFTP Server program on your PC and run tftpd 32 program (TFTP server program can be downloaded from http: //tftpd 32. jounin. net/) 2. Set TFTP Server Directory using the browse button (ex: C: tftp_server) 3. Copy recovery files (u-boot-xxx. bin/fs-emg 80 -xxx. yaffs 2) to the directory 4. Copy recovery file of Boot File System (u. Image-xxx/msp. axf) to the directory (Note 1) Or 5. Copy recovery file of Boot File System (fs-bootfs-xxx. yaffs 2) to the directory (Note 2) Ericsson-LG Enterprise Proprietary | 2013 -11 -11 | Page 3

KSU/VVMU Recovery Procedure 1. Connect your PC to e. MG 80 KSU through Serial Port 2. Turn e. MG 80 system on and press [Ctrl+C] as quick as to log in boot mode. The boot mode prompt: * MBU: ‘e. MG 80 -MBU>’ * VVMU: ‘e. MG 80 -VVMU>’ Note) We assume that all recovery processes are done at MBU board in this document. So you can change the file names for VVMU’s when you want to recover VVMU board. Ericsson-LG Enterprise Proprietary | 2013 -11 -11 | Page 4

KSU/VVMU Recovery Procedure 3. To check the current system’s boot environment, run CLI ‘printenv’. Ericsson-LG Enterprise Proprietary | 2013 -11 -11 | Page 5

KSU/VVMU Recovery Procedure 4. Set IP of TFTP server by ‘setenv serverip’ and ‘saveenv’ command. (We assume that e. MG 80 has 150. 61 and PC has 150. 13) 5. Verify Recovery files’ name by ‘printenv’ command set name if they are different with you have. (Note 1) 5 -1 Set Boot File System name if you want to recover the boot files by one package. (Note 2) Note) Run CLI ‘saveenv’ if you changed one of recovery file name. Ericsson-LG Enterprise Proprietary | 2013 -11 -11 | Page 6

KSU/VVMU Recovery Procedure 6. Update Boot Image using ‘run updateboot’ command Note) This is not necessary if Boot image is not changed. And you should reset your system after updating Boot image. Ericsson-LG Enterprise Proprietary | 2013 -11 -11 | Page 7

KSU/VVMU Recovery Procedure 7 -1. Update MSP Image using ‘run updatemsp’ command (Note 1) Update Kernel Image using ‘run updatekernel’ command (Note 1) Ericsson-LG Enterprise Proprietary | 2013 -11 -11 | Page 8

KSU/VVMU Recovery Procedure 7 -2. Update Boot File System Image using ‘run updatebootfs’ command (Note 2) Ericsson-LG Enterprise Proprietary | 2013 -11 -11 | Page 9

WTIB Recovery Procedure SW 1 CN 2 Figure 1 Board Layout of e. MG 80 WTIB 4 Ericsson-LG Enterprise Proprietary | 2013 -11 -11 | Page 11

WTIB Recovery Procedure -. Search for the CN 2 connector. -. Connect two pins of the CN 2 on the WTIB 4 PCB with a short cap or a jumper wire. -. Connect serial cable with GDC-TRC 1 between CN 1 on WTIB and PC and then, Power on. -. Check if the serial display is normal. 1. If serial display is OK, the factory image is working. 2. If not OK, you must check if U-boot is normal. A. If U-boot is OK, you can process below. B. If not Ok, “U-boot recovery” process must be done before below process. At that time, a special tool like “USB-Blaster” and related files are needed. (The factory image is temporary, so you have to upgrade again the latest version) Ericsson-LG Enterprise Proprietary | 2013 -11 -11 | Page 12

WTIB Recovery Procedure -. Serial Tool Configuration Emulator: Tera Term(Recommended), Hyper terminal, or any tools supporting X-modem. Serial Port Setup: -. Right after pushing and releasing SW 1 on WTIB 4, Hit <”CTRL”+“c”> to enter U-boot mode with “WTIB#” prompt. -. Check the U-Boot version using “ver” command. Maybe 1. 1. 6 or later. Hit the “CTRL+c” at this point u-boot version check Ericsson-LG Enterprise Proprietary | 2013 -11 -11 | Page 13

WTIB Recovery Procedure -. Input “run cupgrade” at WTIB# prompt for uploading WTIB image. Ex) GS 86 U 10 Af. rom -. Send the WTIB image. Refer to below sequences. File->Transfer->XMODEM->Send->Option 1 K click->select the “GS 86 Uxxxx. rom” Don’t select any other file. If so, please click “cancel” button and press “CTRL+c” repeatedly until WTIBE# prompt display. And then, start again from the command After the upgrade is complete, WTIB automatically restarts Ericsson-LG Enterprise Proprietary | 2013 -11 -11 | Page 14

WTIB Recovery Procedure “run cupgrade” progress and result Rebooted automatically Ericsson-LG Enterprise Proprietary | 2013 -11 -11 | Page 15

WTIB Recovery Procedure -. Wait until the TMR LED(LD 2) on WTIB 4 blinks. -. Power off and Remove the Short cap or jumper wire from CN 2. -. Power on and wait until the TMR LED(LD 2) blinks. -. Check whether the upgraded version is correct. Ericsson-LG Enterprise Proprietary | 2013 -11 -11 | Page 16
