dumb cell phone question

Jan 02, 2016 42 Replies

I have a Casio Rock flip phone that I really like, mainly because it's indestructable. I think they demoed it by running over it with a jeep.



But the charging connector is flakey. If I buy another one on ebay or something, can I pull the microSD flash chip from the old one and poke it into the newer one, and have everything work like before, same phone number and provider and all that? Is the entire state of the phone stored on the SDcard?

no, the SD card is just extra storage

on GSM phones the phone number (and if you tick all the right boxes the contact list etc.) is on the simcard, not so simple with most US phones afa iu

around here there a several phone repair shops, but it is hardly worth it f or such and ancient phone, just go get a new one

My guess is not. Most phone have the SIM (build-in or not) and uSD cards separate. To test it, does the phone connects to the network with the uSD card removed? If it does, the SIM is build-in.

Most phone carrier will let you swap phone with just a call. Why not call them?

As mentioned, it's all in the CIM card.

When we bought our new smart phones, the shop we bought them from was able to suck all of the stuff out of the old phones and put it in the new ones.

So maybe choose a reputable seller (Car Toys up here; I don't know if they're Portland only or all over) and ask.

I don't think this phone has one.

I could go to the Verizon store, but it's hard to park there. I was hoping I could do it at home. That's what the bad guys did in "The Wire."

I suppose I'll get another smart phone some day, but I always manage to break the screen, jamming it into my pocket with keys and swiss army knives and stuff. The Rock seems to be unbreakable. I really only want a dumb phone.

I maintain about 10 assorted Casio G'zOne handsets in use by the local building contractors. Mostly Rock C731 variety. Exactly which model do you have and who's the provider? The charging connectors and repair issues are quite different from model to model:

last time I did that, just connected my phone to a box and made copies of everthing I had on the phone and moved it over to the new one. All items in storage, contacts, texts, phone #s, etc..

Three point torx is unusual, but five point is not. For example, this one from amazon:

There's no obvious model number visible. It's Verizon.

It looks like this:

which may be a 731.

If I get a new one, I may as well take it to a Verizon store and let them do it.

Thanks

Oh, there are a couple of recessed gold connections on the side, presumably for the charger cradle. Any idea how they work? They measure 0 volts.

It's NOT a Torx head. It's like a Philips screw head, but with 3 or 5 winds. Also known as a "Y-Type" tip (not a "tri-wing"). Lower right, but much smaller.

The problem is that all of the tips and sets I've wasted money on buying have a #1 Y-type (or misnamed tri-wing) tip. The phone needs a #0, which doesn't seem to exist. I've bought two sets that claim to provied a #0, but they appear to really be #1. Needless to say, the designation of these "security" screws have not been standardized and are probably a Casio exclusive.

It's a C731 if it's for Verizon. There's some documents on this page that might be worth reading.

VZW has an online tool for transfering the phone book: The G'zOne is supported but it looks like it will only do the phone book. This is what they do when you drag the phones to the VZW store.

I'm assuming that you also have service from Verizon. If it's from an MVNO (mobile virtual network operator), such as PagePlus or Net10, things are more complicated.

I would send you one of my spares, but NONE of them are going to work until I get a proper screwdriver. I'll check my stock when I'm back in my palatial office on Tues.

On later models, it was replaced by the now standard and less horrible microUSB connector.

That should work. The cradle connector connects to the battery via contacts near the base of the phone. I suggest you also get another charger as a mangled receptacle tends to also mangle the plug.

There is also a "spare battery charger" that just holds the battery. The problem here is finding a new replacement battery. Most of what I've seen and bought are used batteries. The market for replacements is rather small so there's little incentive to produce new batteries. Fortunately, the batteries in these phones seem to last forever.

I find it easier to do these myself instead of standing in line at the VZW store. Since the sales people make money on sales, not support, they'll do everything they can to trash your phone(s) so that they can sell you a more modern replacement. The *228 thing is very easy and quick. Writing down what's in the old phone and transplanting it to the new phone depends on the number of entries.

Hint: If you use old hardware, it helps to have a working spare.

Methinks those might be the battery charger contacts, but I'm not sure. There might be a diode or charge controller in series with one of the contacts, which would explain the zero volts. Sorry for the vague reply, but I don't have any phones handy to be sure. I'll check my collection when I get back to the office on Monday or more probably Tues.

Good find and now on order. That certainly wasn't available when I was shopping for them about 6 months ago. Thanks.

Argh. The Amazon order page proclaims that it's an "add-on item" which I can't order unless I also order something else over $25. No thanks. So, I got these instead: Not as nicely machined, but might work.

The Y type is Tri-Point, not Tri-Wing. Sizing designations are pretty crazy as you found.

Pretty sure this set has both the #1 and the #0: or

Fry's had the iFixit on promo code a while back and I got one of these sets for about $18.

Also see though I don't like the idea of the standard handle size which is too big for the smaller bits.

The tri point and wing designations are just as mixed as are the various numbered sizes. In addition, the angle of the point varies from about 60 to 120 degrees. I bought one set that where the tips fit, but mangled the screw head or tip (I forgot which).

I bought this similar set, which had the wrong point angle. I thought that the driver specified in metric (Y2.0, Y2.5) might work. Bad fit. I don't really want to try the iFixit set unless I can first see a picture of the relevent tips.

Same problem here: Notice the roughly 60 degree point angle.

Those are all tri-wing, which have the spiral design near the tip. You can see the spiral in the magnified view.

I also tried to contact Casio-Hitachi for information on obtaining proper drivers. No response. Also, later models use a standard T5 Torx driver.

Thanks for trying.

How about trying here? ISHIMARU DENKI MAIN STORE AKIHABARA

Ishimaru Denki operates several stores in Akihabara. Ishimaru Denki Main Store Akihabara focuses on computers and mobile phones.

If you can't find it "somewhere" in Akihabara, it probably ain't from Japan!

Well, since they don't seem to sell online, I'll need to shop in person. A round trip non-stop flight from SFO to Tokyo is about $2,000. I'll have to think about that.
