PBO Bootcode Update (TFTPD/LAN Free) Under $6 and Under 666 Seconds

[supergizboy]

Finally received my USB TTL cable from Amazon, $4.72 including shipping. Color codes are below,

Red --> TX
Green --> RX
Black --> GND
White --> (not used)

Using driver on first post, Windows 7 with HyperTerm on first post. Unbricking my PBO in few minutes. I didn't even connect the White wire. Thanks guys.

People having trouble, if you don't see anything coming on the terminal, most likely your connection is wrong, use multimeter to figure out the color codes on the wires first, each type of cable could have different color codes. Good luck.

Thank you for sharing , I think I will collect all the color coding information perhaps someone can make use of it.

update:
I have already scanned the thread and found 2 reports with color codes. For those who have purchased the CA-42, can you please share the color coding with us if you haven't posted it already ?

I'm asking about wire setup and such because I couldn't find the "dupont wires TPK pin header" and had to do other setup using some power wires from an old pc.

You're most likely have the wires incorrectly connected. I think I have the same cable you do, try this color codes,

Red --> TX
Green --> RX
Black --> GND
White --> (not used)

if you're still having trouble, use multimeter to figure out the TX, RX and GND wires based on this picture. You most likely don't need the VCC wire too, chip getting power from USB.


people pls keep in mind, there's no standard color codes for this, each factory might have different color codes. but the Nokia data connector pins are standard.

I tried this setup, and I get this (strange) connection:



Does this mean I'm still using an incorrect wire setup, or my PBO is a forever broken brick? At least now it's outputing something on my PC screen...

EDIT: GUYS, I got it! I'm going to post the results after I try to flash my unit! I changed my wire setup and now it's working!

I can't get my PBO to detect my flash drive.. I've tried two different ones, but gets stuck in a screen called "box office". I tried to follow the instructions here, but using a P05 firmware, but the usb led on my PBO doesn't light on (just my flash drive led that lights). Any thoughts?

You're doing right just wait some have taken a couple hrs for it to come back up when it boots to the recovery mode.

Oh, ok, I didn't know some people needed hours!!! Thanks!!

Have you erased the flash after you have updated the bootcode ? snappy reported that updating the bootcode didn't get his already mis-matching P05 install working.
He had to issue "erase -m" from the HT to clear the flash, then the unit would upgrade normally.

Yes, I've run the "erase -m" command. I updated my bootcode and ran "erase -m". It's only possible to upgrade the firmware using a flash drive? If I don't know how much time do I have to wait to see if it's working, and so can't know if it's a flash drive/PBO problem, it's going to be difficult...

Though 2 hours is not unheard of, but it can be anything but common.
I would turn off the box, reformat the drive in FAT32 (perhaps use another one), then attempt reflashing (preferably after re-erasing the flash from HT), one sign to look for to know if the upgrade would ever work is to watch for the USB read light (if your USB drive have one), it should light up intensely when the firmware update starts (because its copying the file) then it would intermediately flashes afterwards, the whole upgrade shouldn't normally take more than 5 minutes (be sure to use composite).
