BB5 cable don't work with VPP - GSM-Forum

darkchina · 12-31-2007, 15:56

hello PLEASE help with cables as I don't know what to think anymore.

I am talking about BB5 cables with RJ45-8pin, that goes to MT-BOX with 10-to-8-pin adapter.

if VPP wire is connected cable WON'T WORK. phone won't enter local mode and MT-BOX won't read phone. please note that phone powers in offline mode.

if I cut VPP wire phone enters local mode and MT will read phone. everything should be ok but I WONDER IF SOME PHONE MODEL ABSOLUTELY REQUIRES VPP.

I checked cables and adapter several times and they are wired correctly.

I suspect there must be a modification to make VPP work with BB5 but I can't reach it.

PLEASE HELP - MY RESELLER DON'T UNDERSTAND THE PROBLEM -

IF I DON'T FIND A SOLUTION I WILL END UP SELLING MT-BOX AND BUYING ANOTHER FLASHER.

if cables is for a JAF not for MT-BOX then need to reconnect VPP wire mate!!!!!!!!! Use needed cables ! JAF and MT-cables is different

darkchina · 01-02-2008, 12:08

thank you for your time, but I thought my explanation was clear enough.

I don't know if cables are for JAF, but it doesn't matter. I have TOTALLY REBUILT cables with schemes found on mt-box support site.

with VPP connected, BB5 phones don't enter LOCAL MODE.

please post a schematic of the 10-to-8 adapter as I suspect it may be the problem.

sometime need to use support site!!

darkchina · 01-02-2008, 17:56

thank you sir, but please don't treat me as a beginner only because I have written least that 10 posts...

I already made the modification to the adapter, but VPP isn't still working...

how come?

911GT · 01-02-2008, 18:05

Ok mate but if your box is from latest version not need this modification.
1st try to download mt2com from support site and start it. make vbat to 4.2v and vpp to 10v.
Take a multimeter and mesure it to be sure all is ok.Post result and i will try to help you.

darkchina · 01-02-2008, 18:30

VBAT is 4.17 - VPP is 9.78

I will send my box serial number to you via PM.

Not Need Mate All With Your Box Is Ok.find Problem On Another Place

darkchina · 01-03-2008, 11:58

thank you sir, so... as you say, I DO NOT need to modify the adapter.

I understand... so please now give me a hint on where to look for the problem, as I am sure that all cables are wired correctly... I don't know what to do more...

911GT · 01-03-2008, 13:20

yes you dont need to modify your adapter mate. just try to mesure with multimeter VPP on a any cable for phone.May be he is shrtcut to GND in 10to8 adapter

darkchina · 01-04-2008, 12:28

so... I have checked with multimeter and there is NO shortcut... I have built a new adapter from scratch, with 47K and 200K modification. I post here the log of what happens when I press the OK button.

THIS IS WITH ORIGINAL ADAPTER, NO MODIFICATION:

============= Set Flash mode for info =============
VBat is 3.93V

Vpp pin has 0.10V, Not Connected
Pins:
Mbus 1, Box Tx 1, Box Rx 1, Bsi 0
Boot...
rap3gv3_2nd.fg
RAP3Gv3_algo.fg
BOOT OK...
Phone Type: BB5

AND THIS IS WITH NEW ADAPTER, WITH 47K AND 200K RESISTORS:

============= Set Flash mode for info =============
VBat is 3.93V

Vpp pin has 0.00V, Shortcut go ground
Pins:
Mbus 1, Box Tx 1, Box Rx 1, Bsi 0
Boot...
rap3gv3_2nd.fg
RAP3Gv3_algo.fg
BOOT OK...
Phone Type: BB5

the only difference is marked RED. phone used for test is 6233, and I REMOVED check from "disable VPP".

what can you tell me now?

911GT · 01-04-2008, 13:50

i dont have an idea.This is very strange.

darkchina · 01-04-2008, 18:10

well... I understand, but this does not mean I am gonna give up. there must be something, and surely it can be fixed...

are you sure my box doesn't require modification? it has been exchanged for fault while in warranty, so maybe the serial number is new and the hardware is old...

is there any other thing I may check with multimeter? I can open box if you want... damn it I wanna fix it!

911GT · 01-06-2008, 14:48

box work fine mate.When you set VPP he is ok with multimeter.
