The OS need to be updated or reflash

2. You need to install a BlackBerry OS file that is specific to your device. The original version, as supplied by the carrier, is the safe choice, but you can use any model specific version. This is not supplied on your BlackBerry CD, Ref: 3 links to BlackBerry's download pages.

3. Once the OS has been installed, you have to prepare it for the device.

Select Start / Computer and select the Drive C: Icon.

Open Program Files / Common Files / Research in Motion / AppLoader.

Navigate to the bottom and delete the file Vendor.XML file.

4. You are now ready to restore your device. Verify that BlackBerry Desktop Manager is NOT running. Plug the device directly into the computer's USB port.

We are about to venture into the bowls of the beast. Windows is not suitable for this job, we are going to invoke the Command line interface with an option switch.

Windows XP: Start / Run... / Command

Windows Vista: Start / Command (type this into 'start search')

2000 Isuzu rodeo headlights not working

daytime, running lights are mandatory there, not in USA !!!
ILL NOT GUESS ! (is that what you want, just wild guessing?)
just the head lights fail?
on high beam, slows and flashed? yes?
and all else is ok (even engine runs and car drives ok>?)
no power, what does that mean, using a voltmeter?

exterior fuse, my guess that means engine by fuse box,.
PDC, real name , names dont matter, but locations do..
my guess, is there are lot of things dead, not just head lights
but they are #1 first fix.why because they operator KEY OFF.and are a primary power feed.

so does battery have 12.6vdc rested.
are the battery terminals cleaned? all 4 ends. (not short it fiddling it)
if yes, then check the power in the PDC box.

ill look at for you, just a moment.....
(the schematics are best to use fixing any car)

ill pretend all else is ok, just HL failed, dead.(hi/lo)
HL 101:
the main box, must be hot, 12v there. HL ON.
the HL relay must close HL turned on.
The HL relay feeds 2 fuses next LEFT and RIGHT HL
if both fuses are hot, the ReLAY is good.

the engine bay fuse box EB has a 100am fuse and 50amp
both must be hot, both sides, hot means 12vd.
is it ?
that is first. as you told me there is no power external, so
i assUme the box is dead.
if not dead, then the relay is next.

see below your HL schematic
see relay see pin 2,
pin 2 must be 0volts headlights on.
if not the switch is bad below left or ground to it lost.
lets pretend it is 0v.
so we check relay pin 1 (output)
it must be 12vdc or the relay is bad.
pin 2 is 12v.
as is pin 5 at all times (called hot all the time )
these above steps finds all both HL dead. (not fuse blown)

Canada does use different lighting, as do all countries, by LAW.

How to fix no lowbeam headlights on 97 geo metro

did you check the HL fuses? x2
are both dead? or just one?
Highs work , right,?
would you like to guess, ?
or test? have a volt meter, and a schematic.?
DRL or non DRL system? (daylight running lamps).
2 systems, DRL is mostly in CANADA but no always,
when did they both last work, dont know, or last week>???
if dont know, why not test the lamps to see if they are good
using any 12vdc battery over 5amp current.
or use and OHm meter on the filaments, for lows. 0 ohms good
infinity bad.
to go father, we need what type HL system is on car.
DLR or not. DLR love to fail. for sure.

I have a 1997 jeep grand cherokee laredo and my headlights stay on after shutting my jeep off,

head lights are designed to work , with no key near car.
its a safety feature. lights always must work. (all answers USA)
this car has many options and funny business with lamps.
like automatic HL sensors.
HL sw. auto, off , park low, see auto, bingo. that option.
on this car the HL switch is ONLY a digital input to the BCM.
body puter.
option 2, is DRL, daylight running lights, GOT DRL?
if you had a real FSM, you'd see all this STUFF.
i will not explain your system. in word, the FSM has 10 schematics on this complex system. (vastly complex to my simple wrangler)
the HL are both grounded
so the system applies 12v power to make them glow.
the 1st fail path is DRL, it can fail and turn them on. (unplug it?)
there is a head light relay that can stick on, or is commanded to do so.
i start there at the the relay.
im sure your relay is closed (enegized) full time. (wrong)
this is because it is bad (pull it see lamps go off , proof)
if pin C10-12 (85 coil) is low , not 12v, on the relay , it is being commanded to be enegized.
there are 3 things that can do that.
1: BCM, body computer sees you switch HL on.
2: automatic HL (dark outside) tune them on. (not key off)
3: DRL (not key off)
so if Auto HL module fails, it can in fact energize the HL relay.
unplug it.
if the DRL messes up, it too can energize the HL relay.
so unplug them all 1 by.
Auto HL module
DRL module
last BCM connector C2 pin 12, pulled, cuts the BCM.

any can fail.
oddly the DRL can mess up the low beams and high..

Emergency lights, brake lights and hight beams work but the tail lights and heads lights dont come on and work. What could be the problem

fuses, check all fuses. 1st.

this car has diffr. path for park/tail lamps (same path as cab lights)

just a switch (park) turns them on, NO RELAYS.

there is a high beam relay marked, dimmer. and

a HL relay (head light ,low beams)

both fuses can't blow on HL, lows. no way.? huh? but seen it with a berserk Alternator.

all answers USA< not canada or? with DRL. so... do post country. or Honda market code, KA is USA.

i always check the HL relay 1st. (lows)

HL are hot all the time. no key needed at any time (easy)

i always go to the mid point in the circuit. (saves 1/2 the work)

i go to the HL relay; 1 checks here.

1: power contractor pin, input, 12v all the time, if not fuse bad.

2: coil top pin, 12v all time ,same answer.

3: HL on, coil bottom 0v, if not the combo switch is bad.

4: HL on, contactor out 12v, if not and above ok, Relay is bad.

the book is here, you can see the HL in chapter ,23 .

if not usa or car has DLR?;, do say so, nobody ever does, but do.
