trouble flashing samsung A640....cannot read in CDMA

[jayala719]

Hello! I've got a few Samsung A640's that I am trying to flash to cricket. When I open up CDMA and try to read these phones, a grey screen pops up on the phone saying something like:

Test Mode <A>

Suspend

FM_RX_FLAT
[ch]0991 000 (then the zeros flash and turn into '~' symbol)

and then the phone power cycles.

Is this a firmware issue?

do they all do that? and does this repeat? and does it only do it when plugged? try to read it with the phone off

[rich hathaway]

have you tried using samsung pst with the proper .dll

Yes, all 5 of the A-640s I have do this. And yes it does repeat.

These are the steps I take:
1. Click Connect says "Phone connected successfully."
2. Click Read phone does this: (See Pictures)

the CDMA says "Ready...Phone is set to DM Mode" but the phone is powercycling and when it comes back on I try to unlock and it says "Failed...Phone does not answer..." when CDMA just told me that the phone was connected.

Is there an easier way to flash these? SamsungPST? Haven't tried that yet....

thats what you need to use (samsung pst) if your phone does not ever boot up and work properly you will need the bin file and dll for it to get it working again. if it is booting up and ok,just flash it with pst and the dll. there are several guides here on the site for using pst. the dll is here also if you cant find it i wll put it up for you.

Do I use SamsungPSTLite or the Full version??

I tried SamsungPSTLite. Loaded the correct SCH-A640 .dll and when I go to Read General Information it says No Response.
I try to go to the Settings Tab, Select All, and Read from phone, but then I get this message: This phone is not identical with this module. Please select another module! (It prompts me for the MSL code before this process, but I don't know it because I was unable to read this phone under CDMA, which is what I use to find SPC/MSL codes for most phones.....is there any other way to find out this code?)
