- MOTOROLA "TRIK-CLIP"
-
- This is the plans I recieved for the Flip. Supposedly if one knew the
- pinouts on the other moto phones one could transpose. (maybe!) I never
- tested this so I don't know if it works. The chip in the flip the text
- is talking about is a 32 pin square plcc
-
- After Phone Disassembly Locate 27c512 Eprom on phone board. This is
- On The Upper Right Side Of The Display Next To The Roam Indicator.
- This Is a 32 pin Square device. **Note the dot and beveled edge
- for pin orientation (the dot is pin 1) Count to the left
- counter clock wise 2 3 4 5 and so on. To the Right or clockwise
- of the dot is pin 32 Vcc. This will aid you in your count to find
- pin 25 which is the eprom output enable. This pin is at ground or
- Vss - Level. **Note Pin 25 on Eprom in phone must be lifted from
- the phone board ground or Vss state. Use an X-acto Knife and or
- soldering iron and tools to cut pin at board level where pin
- narrows. Do not bend wide part of pin up on eprom as this could
- break off of Eprom. Also Wide Part of pin Will be used to make
- contact with eprom test clip adapter. The eprom test clip adapter
- will take pin 25 to logic high through an 8 to 10 thousand
- resistor to pin 32 Vcc. This will Gate off all data Commands from
- the phone board eprom and allow the eprom test clip adaptor to
- take over. **Note test clip could touch narrow part of cut off
- pin on board and cause phone not to power up please remove or fold
- down as low as possible so test clip only touches side of eprom.
- After programing is complete put pin 25 back together or find a
- suitable ground or Vss - source. The phone will power up and work
- without pin 25 put back together but for long term precaution
- put back to a logic zero or ground to enable the output enable.
- To use the eprom test clip adapter pull the locking wedge on the
- test clip into the upper postition. Seat the eprom test clip adapter
- onto the eprom in the phone. Make sure to orient the dot and
- beveled edge with each other. Push the locking wedge down to lock
- the the eprom test clip adapter onto the eprom in the phone. Hook up
- the programing cable to the computer and plug into the jack on the
- base of the phone. Also hook up the loose lead with a jumper to the
- center terminal between the battery contacts. Turn power on green
- light on phone display should come on thgen a complete display test
- will light up after that the no service will blink along with the
- signal level mark in corner of display. If the antenna is still on
- the phone it could change to roam or something else. I suggest
- remove the antenna so the cell sight will not see you. If you do
- not get a power on test with the display there are 3 possible
- things (1) pin 25 on phone board is touching the test clip this
- can be checked by looking with a volt meter at pin 25 where
- resistor connects for 4 to 5 volts pos with reference to ground.
- (2) Test clip is not sitting on chip good some times you have pull
- the test clip up off of the eprom a 64th of an inch all the way
- around. (3) there is corrupt data, Pull the eprom test clip off
- Phone check to see if power on display is there.
- Computer see if data or phone number or cell sight code or data
- whole is ok I've seen the cell sight ID corrrupt and the phone play
- dead on the power on test. The test clip sometimes needs
- maintenance look at the gold pins.
- Make sure all the pins are level with the edge of it. If not take
- an X-acto or pin and lightly bend them out so they are along the
- edge of the plastic of the test clip.
- Always check to see if eprom in phone contacts are clean before
- putting test clip on. **Note when test clip is on phone - only
- change the ESN only. *The other data phone number lock and so on
- can be changed without the test clip and and should be done so.
- The software version in the test clip is 9148 you will see this in
- the right corner of the computer. Sometimes the program will crash
- during the ESN wright this will put all zeros in the ESN field
- check the test clip try again. Sometimes I've had to do this 3 an 4
- times. Also watch the phone display for codes I've seen at the end
- of a wright the code (FO8) just before power down I've had no
- problem there but during the key wright (FO8) means i've crashed.
- Also during the time when the program is counting back into the
- phone i've had (F1O) show up in the display of the phone this
- problem means the next time you may not get the power on display
- test pull test clip read phone check data to see if cell sight
- code is corrupt or some other data correct try again. A word of
- caution do not push on eprom on top of test clip as this could
- seat eprom lower into adapter and cause bad contact. To remove
- test clip pull locking wedge up to unlock the eprom test clip
- adapter from the eprom in the phone. Continue pulling up to lift
- the eprom test clip adapter from the eprom in the phone.
