Information Possible solutions for failed tftp-recovery
My T48G stuck on initializing at the welcome screen. So I tried to make a recovery with tftp but the phone didn't finish the recovery process. I retried again and again with no success...

Before you have to read the whole Story, here my solution in short words:


Check if the connection and download from the tftp is fast enough.
Maybe a faster server can solve your problem too! Wink

And here the whole story:
At the beginning I used the tftp-Server of provided by my VoIP-Carrierer for the recovery. But as I already said, I retried again and again but the phone didn't finish the recovery process.

So to get a litte bit more information what the phone is really doing, I setup a tftp-server on my internet webserver with the recovery files and used this server for the next recovery-try. But with no success. The recovery took endless time and never came to an end.

I checked the Logfiles of my tftp-Server to see what is happening. And it looked like the phone is download the first file "T48.bin" again and again:

Code:
Mar  9 22:38:38 server in.tftpd[7610]: RRQ from 93.205.xxx.xx filename T48.bin
Mar  9 22:40:33 server in.tftpd[7635]: RRQ from 93.205.xxx.xx filename T48.bin
Mar  9 22:42:28 server in.tftpd[7652]: RRQ from 93.205.xxx.xx filename T48.bin
Mar  9 22:44:23 server in.tftpd[7671]: RRQ from 93.205.xxx.xx filename T48.bin
Mar  9 22:46:18 server in.tftpd[7692]: RRQ from 93.205.xxx.xx filename T48.bin
Mar  9 22:48:13 server in.tftpd[7709]: RRQ from 93.205.xxx.xx filename T48.bin
Mar  9 22:50:08 server in.tftpd[7887]: RRQ from 93.205.xxx.xx filename T48.bin

The Strange thing was, that it looked like the phone is restarting the download after nearly exact 2 minute. So I tried to download the file from the tftp with my computer and checked the time download time. It was about 3 minutes! My Internet isn't so slow, but you should no that tftp is always a slow kind of file transfer.

The next step was to install a tftp-server on a local computer in my network, store the files there and retry the recovery with this server. AND NOW IT WORKED!!!!
