The Jtag procedure worked, but now I need the "Recovery files".

The PDF instructions I was following said that the files would be included in the "package" with the PDF. All I have is the PDF.
I tried searching around for them, all the links I've found are broken, or, they are on some forum where I don't have access.

I'm not even sure what files I need...seems like some kind of a recovery Linux to reload to the box to be able to get back to where it will accept a regular bin file.

But, at least I got this far, past the point where it would have crashed if it were a trashed box [smile]

BTW, I did find the whole package. And I completed the procedure. I had a little trouble knowing how to use the Filezilla/Pumpkin thing, and maybe that's why the receiver didn't boot after I finished the procedure??

I think, I'll go through it all again, now that I know what to expect and how to do some of these things!!

I was working on it all day!! Finally finished at about 2 AM. Felt good to finish, but disappointed in my results [wink]

techjunkie02,

Do you have a Menu now? It may show you where the Firmware,if any is kept in the machine.

I have seen some equipment that all the firmware versions were kept in a special internal Ram area.
This was so that if a piece of firmware was buggy the user could install a stable version.

After I removed the JTAG and re-booted, it went back to just displaying "BOOTING".  The last step was loading a "VM Linux" I think it was. I messed that up at first because I didn't know how to use "Pumpkin", so then I went back and did that part over, so I may have corrupted it by doing that! But the machine was responding correctly to all the commands, etc... I'm pretty sure I messed it up.  I'll probably give it another try later, now that I know what to look for, and I finally got that cable made [smile]
Thanks,

Sounds like you almost there.  I looked for my files but couldn't find them as they must of been on my hard drive that crashed a few years ago.

Thanks Emil.... I found the whole package on another forum. Instructions in 3 languages, Files; Filezilla, Putty, and Pumpkin, then azfiles; vmlinux.bin, update, and backup-kernel.... wish I had found this in the beginning instead of after I had been working on it for several hours..LOL!!

if jtag is working then flash the whole firmware instead of just the bootloader...no need to setup a tftp server.

Merkin, thank you!  Could you please either PM me the procedure, or reply here with it?

I was merely following the instructions for the recovery. How do I flash the whole firmware using the Jtag?

Thanks in advance [smile]

The one I just used on it is a USB to TTL Rs232 adapter which I originally got to restore the MicroHD receiver. It worked after I made an adapter cable to bring out only Rx, Tx, and GND to the Azbox. I think it's a PL2303, or something. That allowed me to do everything that was in the instructions that I followed, I was able to use PuTTY and send and receive with the AZ.

I also have the USB BDM NT that I used on the 922, but I don't think we need that for this.

I think my problem was I was trying to follow mixed instructions, and had a tough time understanding some of them, and I KNOW I did some of the things wrong at the end when I was loading the files to the AZ. I stopped and went back and tried re-doing, but I guess it was too late.

BUT, while I was in the middle of doing all this, I did find, finally, the complete "Recovery package" that had nice clear instructions(in 3 languages [smile]) and all the files needed.

FYI, I had been working on this all day, and it wasn't until very late that I found that package, and I "finished" at about 2 AM, I was tired and put it all aside. Planning to go back to it maybe today, and start over again, from scratch, following the instructions. Hoping that my learning experience will get me through it successfully this time [wink]

Thanks,

usbbdm nt = not jtag 
rs232 > ttl = not jtag

jtag is only necessary if the bootloader is damaged.  

follow this guide to get a serial session running
https://kb.cyberoam.com/default.asp?id=2193

then power up the azbox and copy+paste the result.  if nothing spits out then you got to swap your tx/rx lines.

Okay, maybe JTAG is the wrong terminology to use here.
The AZ does not have a serial port that I can see.... I believe that's what the 4 pins on the board are for,
and that's what I connected my "USB rs232 to TTL cables" to and established the serial connection using the puTTY software.... that all worked properly. I had the connection and was able to send to and receive from the AZBOX just fine.

I haven't started back in on it yet. Don't know when I'll get to it, got a couple of other things I need to attend to, and I want to make sure I have plenty of time to go through this all the way in one sitting this time!!
Thanks again [smile]

techjunkie....   Thanks for posting that.  That's good info in case we really mess up our Azboxes.
However, unless you think it's at a site that Rick wouldn't want posted, I wonder if you could indicate where you found the files needed?  Looks like you need

backup_kernel
update
and
vmlinux.bin

Fellow Members, your posts are welcome here! Do not worry about posting everything perfect. Different receivers and LNB's will give you different Frequencies and Symbol Rates. Some set top boxes, PCI cards and USB receivers, Do Not Require all of the same information that others may need. It is not Required to post everything that others may need to tune in a feed. It is just most important to share the find. We can always adjust the Frequency and Symbol Rates and try the various Modulations and FEC's on our own receivers until we get a lock and then give a polite reply with what works for your receiver, as that information might help others as well. We all appreciate the efforts and energy of the Posters!
