Treo 750 Bricked or Not?

[QuakerOatz]

So I got in this situation by running step 1 of the cheetahunlocker with a CHEETAH.grh file on the SD card. Everything worked (I got OK) on everything but the "OS" flash never finished, just stayed on 90% progress and never moved.

Yes I didn't do a hard SPL, I was trying, but for some reason to hardspl process grabbed a ROM off my SD card and ran with it.

From the various searches I have found that I should get a stock ROM, reflash with this.

I do not have a "Stock ROM" and cannot find one anywhere. Also how would I even flash this ROM if I had it? I would assume I would drop this ROM on the SD card (FAT 32, and rename properly) but where do I find the elusive stock ROM?

I cannot use active sync or anything, my phone with only boot into the bootloader (red/blue/green)

I have an SIM unlocked 750:
- On reset with no SD my phone hangs on the Palm OS progress bar
- On reset + PTT with no SD I get:
Palm Tr
IPL-0.20

Palm Tr
SPL-0.24.0000
- I've tried the cheetachunlocker, step 1, says my image file is corrupted at 7% progress.
- I've tried the athena_unlocker.exe with cheetachunlcoker.exe method, no dice.
- I've tried various ROMs on the SD and none of them seem to go anywhere.

If the answer is "Use your backup ROM", I don't have one. If the answer is "find a stock ROM", where????

I do have another 750 I could "backup" and then use this backup to flash my bricked 750... but how to backup the good one? How to use this backed up ROM to flash the bricked one?

Thanks in advance!!

Stock ROM would be the ROM that was officially shipped with the device, either a carrier branded version or Palm's own version.
Since you said your device was unlocked, it could be one of two possibility:
1. You unlocked it by asking the carrier to provide you with an network unlock code or by purchasing a network unlock code from a 3rd party vendor.
2. Your phone was purchased without a contract tied to a carrier so it was a Palm branded unlocked Treo 750.
Which is it?
This will determine which stock ROM you should run.
And ALL stock ROMs are floating around here or some other forum somewhere...

Here's a link to download the 2.23 ROW ROM for the Treo 750: http://rapidshare.com/files/173145556/Treo750_2.23_ROW_WM6.rar
ROW=Rest of the World; Official Palm ROM

Great thanks for that, now how to use this file correctly, now that I screwed this up the first time. I can't use active sync, can only get to the Bootloader Red/Blue/Green screen.

Should I extract the cheetah.rgh to SD and do a reset? I don't think that has been working for me but will try again with this different ROM

Thanks!!

So I downloaded the ROW firmware from above, copied to MicroSD and did the old reset+PTT button.

The screen flashes with "Loading..." for a moment and I'm back to
Palm Tr
IPL-0.20

Palm Tr
SPL-0.24.0000

What next? Thanks!

Hey I might have a solution here:
When you format the Mini SD card, do NOT do a quick format. Uncheck that box and do a full format, FAT32, Default Allocation Size.
This took over 15 minutes for me.
Do a scandisk (Right click the drive/tools/scandisk) and check "Fix Errors". This should ensure your SD card is in good shape.
Now copy a good ROM to the card and reset+PTT. The Palm should flash successfully now. If not your ROM may be corrupted.

Hope this helps! It worked for me!
:D

Glad that your phone is up & running.
Those who brick their Treo 750 should be able to follow the procedures mentioned here & other related thread to recover their devices as long as the bootloader screen is able to display.
