How to unlock a Palm Centro

I want to know how can I unlock a Sprint Palm Centro, to use it with another Service provider, since I have moved to another country. Any Ideas?

Unlocked phones normally refer to GSM networked phones - a Sprint Centro has a CDMA radio in it.

Problems unlocking a Palm Centro

Hi, I bought a Palm Centro locked to Telstra for my son. I have made 3 attempts to get this phone unlocked from Telstra:
1. Went into a Telstra shop, they rang the number for unlocking phones and I was given the unlocking code. Unfortunately this was given incorrectly by someone who spoke English as a 2nd language, made worse by being in a Telstra shop in a very busy shopping centre. This person got the "slash" mixed up with "hache". I followed their instructions, but couldn't get the unlocking to work and decided to try later at home. Still no luck.
2. A few months later (son still in primary school at this stage), I tried again by ringing Telstra and explaining the problem. I got transferred to several different sections, but ended up being told that I had to ring Palm. I rang Palm, got to speak to several different people, got told that it was a Telstra problem. Rang Telstra again, got the run-around again, decided to give up for a whole to preserve my sanity. Each time I spoke to a different person at Telstra or Palm/HP, I had to explain the whole story.
3. About 3 months later, I decide to try again and managed to find a Telstra shop not in a shopping centre, explained the problem. The first bloke struggled to understand what I was saying, passed the matter off to the second bloke, who was "the technician", but he still couldn't sort it out. He told me that it was a software issue and that the phone would have be sent interstate for servicing, with a hefty fee just for them to look at it, and it would take about 10 days. Meanwhile son is at high school and not having a phone is now a problem.
Here's what happens:
The screen says Phone is Off. When you try to switch it on, nothing happens. It doesn't matter which type of SIM card you insert, the Centro just doesn't "see" the SIM card. This did not happen before the first attempt to unlock. I do not think that the phone is damaged, although it's possible that the software is now stuffed up because of Telstra's instructions.
I have the unlocking code, I have the IMEI - what I need to know is how to get this phone from Limbo-land, or wherever its phone function has disappeared to. Can anyone help?

SAME THING HAPPENED TO ME TODAY!! I went to the ATT store, they said i would have to call the business number for them. Long story short, they told me my phone was "unavailable to unlock". The guy said that usually in the unlock box on their system, it would show a reason as to why it can't be unlocked, but showed just unavailable. It's only been 60 days for me; but a somewhat pricey alternative is here. Good luck

How to charge your Palm Centro via 64-bit Windows, with a USB cable

Here is a way to recharge your Palm Centro on your 64-bit Windows computer, through a USB cable. But first, a few brief explanatory notes...
Note 1: I have successfully used this method to charge my Palm Centro from my 64-bit Windows 7 computer. This method probably works for other Palm devices and other 64-bit Windows versions (XP and Vist)... but I haven't tested this on any other configurations. Others may feel free to post their successes or failures with their setups.
Note 2: This method will NOT allow you to HotSync your Palm to the computer via USB. All it does is let you charge your Palm via USB. If you need to HotSync your Palm, and you have 64-bit Windows, you have to use Bluetooth or some other method. To learn how to use Bluetooth to sync, search for "bluetooth sync 64-bit" or something like that on this forum.
Note 3: If you're wondering why someone would need to use this method - why not just plug the phone into a wall outlet, right? - it's because the Centro's charging jack can get messed up. Mine has not worked properly for the last several months
Note 4: I will not be posting any follow-ups to this message. This is my first (and only) post here... I'm posting here because I am very grateful to this forum: It is here that I learned how (and why) to sync my Centro to my computer via Bluetooth, because Palm doesn't support 64-bit Windows. This is my way of saying "thank you"! I'm not trying to be harsh by not following up... it's just that I won't be checking this thread, and I don't want anyone to have bad feelings if they ask questions and I don't respond. I'll be as thorough as I can in this one posting, though.
Note 5: I cannot claim credit for actually discovering this solution. I found it after HOURS of looking online... it was on some obscure website. Unfortunately, I can't remember where I found the original solution, so I can't credit the discoverer here. However, I have done my best to provide much more detailed instructions here.
Note 6: Lastly, Palm should support 64-bit Windows. Period. Some of you may say, "It's not Palm's fault - the company that makes the Palm OS is Access, and it's Access's fault for not supporting 64-bit Windows." Well, this may be true, but Access has stated that Palm has not requested a 64-bit driver. (In fact, you can call Access and ask them directly.) And if Palm doesn't ask (and pay) for it, Access sure isn't going to create one on its own. I used to LOVE Palm devices... I've used Palms for 12 years now, and for most of that time, I heartily recommended Palms to all my friends. But, between this problem and the other problems I've had with my current Centro and my previous Treo, I'm done with Palm. No more for me.
OK, here's how to charge your Palm (finally!)
1) If you haven't done so already, install the latest version of Palm Desktop / HotSync on your computer. You can get this at palm.com, under the "support" section. (Actually, I'm not sure if this is necessary, but I already had done this.)
2) As you're installing the software on your computer, toward the end of the process, do not actually sync your Palm to your computer. Just cancel or whatever you have to do to avoid that step. (Remember, the whole point here is that Palm does not have a driver compatible with 64-bit Windows, so you won't be able to sync via USB.)
3) If you don't already have it, get the PocketTunes application (also known as "pTunes") on your Palm device. If you have to install the software, you may need to do so wirelessly or via a 32-bit Windows computer (because, again, Palm doesn't support 64-bit Windows).
4) Connect the Palm USB cable to your computer. If you are using a desktop, plug into the USB ports on the BACK of your computer. These ports are directly powered, whereas the ports on the front of your desktop may not be. You'll want as much juice as possible to charge your Palm.
5) Connect the Palm USB cable to your Palm.
6) Turn on the Palm device, and open the PocketTunes application on your Palm.
7) PocketTunes will try to connect to Windows Media Player (on your desktop). Tell your desktop to connect to Windows Media Player. (You can save time by telling your desktop to do this automatically.) When PocketTunes connects with Windows Media Player, you'll have a power connection via USB.
8) PocketTunes will eventually show that it is "Idle" on the Palm.
9) To confirm whether the Palm is charging, look for the charging light (on the Centro, it's on the upper left) to turn solid red. You can also hit the home button on the Palm to see the battery / charging status. To get the charging working, you may have to exit PocketTunes and come back into it a few times before the charging light comes on. I have no idea why you have to do this; I just know what I wind up doing sometimes. You don't have to unplug and replug the phone from the USB cable, or turn the phone off and on. Just leave PocketTunes and come back to PocketTunes.
10) If you exit the PocketTunes application on the Palm, the Palm will still charge - but you'll get the constant and annoying "no driver" noise from Windows. To avoid that sound, just keep the Palm on PocketTunes while you have the Palm plugged into the USB cable.
11) You can close Windows Media Player on the desktop once you have the Palm charging.
12) Once you have this set up properly, you can speed up the process by setting the HotSync cable button to PocketTunes - after all, that button no longer needs to be set up to HotSync via USB cable.
When you have everything set up, here's what you would be doing on a regular basis:
-- Plug USB cable (which is already plugged into your computer) into Palm
-- Hit HotSync button on cable --> This starts PocketTunes --> PocketTunes automatically opens Windows Media Player on the computer
-- See if charging light turns solid red --> If not, exit PocketTunes, then hit HotSync button on cable to start PocketTunes again
-- Repeat until charging light turns solid red (success!)
-- Once the Palm is charging, close Windows Media Player on desktop
Best of luck to all who need this!

Why do you want to create your own driver instead of what comes with the device? If you go that route, you need all of the low level USB RAW protocol from the vendor. Did you get that? Yoe are wasting your time if you don't have that. Is the driver from the vendor documented? If it's a USB connection, how does that connection show up in windows device manager?

On the Centro, go to Hotsync and press the icon in the middle of the screen.
Click on the following link for the support page for your device on the kb.palm.com webpage.
http://www.palm.com/us/support/centro/centro_att/
There are links on the page to the user guide, troubleshooting, how to's, downloads, etc.
There are cables available on-line that are the correct sync cable. Just do a Google search for the hotsync cable for Palm Centro.

Does the device have your data on it and do you want it copied to her username? If not hard reset the device and when you do a hotsync pick your wife's hotsync name in the list. If you want to keep the data go here this will tell you how to delete the device username so you can sync it to the correct username. http://www.palm.com/cgi-bin/cso_kbURL.cgi?ID=33416

Setting up Bluetooth HotSync - Palm Centro, Windows 7, 64 bit

A couple of days ago I posted on here trying to figure out how to HotSync my Palm Centro with my new computer that has Windows 7 (64 bit). I followed the instructions - had to go and buy a Bluetooth Adapter for the computer - and went through the instructions from the sticky that was pointed out to me in my original question. I'm to the point where I'm trying to set up the phone to do a Bluetooth HotSync but when it's searching for computers it doesn't find any...
HELP!!!!! What do I need to do now. It may take me a couple of days to get back if anyone answers this quickly because I have a very hectic weekend but any and all advice is appreciated. Thanks.

Thanks for sharing your solution andygc!

Brazilian Palm Centro firmwre upgrade

Hi,
a few years ago Palm released an update for the brazilian version of Palm Centro that solved an intermitent freezing problem whit incoming calls.
I have the files needed to upgrade the ROM but I forgot how to start the Palm Centro from SD Card as the updating procedures says that we need to copy all the files to a SD Card and start the phone from the card.
Can anyone here tell me how to start the Palm Centro from SD Card?
This question was solved.

Try this Palm/HP Knowledgebase article:

It happens to be for Sprint phones, but the memory card update procedure is detailed. Hope that does it for you

Palm Centro Unlock Button

The key unlock button on my Palm Centro has ceased to work. The only way to access the phone is to remove and replace the battery then use it before it goes to the sleep mode. Has anyone else encountered this problem, and how did you solve it?
Thanks,
1oldgeek
Post relates to: Centro (AT&T)

No, I have not installed any new software lately. I started having the Keyguard problem a week or two ago and it was intermittant. It would not work at all for several hours then would start working normally for a few hours. About the time I was ready to give up on it, the Keyguard would start working again. Finally, two days ago, I could not get it to work at all and had to recycle the battery to get to the phone to turn it on or off or make a call. That is when I did some research and found out how to disable the Keyguard function. It appears to working normally now except that the Keyguard function is disabled. Do you think I should do a hard reset?

How Text Messages Are Stored on Palm Centro and possible recovery

I come from an extensive IT and programming background with emphasise on databases. I need some high level understanding of the text messaging system on a Plam Centro system with ATT.
Questions are related to Recoverying Deleted Text Messages
1. Do all incoming and outgoing messages get written to the messages_database.pdf on a Plam Centro (ATT)?
2. When a message is deleted, would it be correct to say that the message is not physically deleted but just that a record pointer in the database (messages_database.pdb) is reset so the messages appears to be deleted?
Why I ask, is that I see a many many requests for people (myself included) of wanting to recover deleted text messages. (i.e. my 16 daughter will not email now becuase we check email but she does text unknown people constantly and it makes it very hard to keep her safe). When she syncs her phone with her computer, the messages_database.pdb file is in the backup directory and if you open it with a text editor (notepad.exe) you can see only messages that have not beeen deleted. She usually deletes all her text messages. There is A LOT of extra data that appears to be encrypted and is not readable.
Is it possible that the text messages are there but just that the database record pointers hve been reset OR are Plam text messages written to RAM some how; although that does seem to be the case, since when you sync, the messages_database.pdb files has any and all messages that have not deleted.
It woul be VERY valuable (and I think profitable) if someone very high level knowledge of the messages_database.pdb file could write a PC application that would alloow you to undelete the text messages. I know there are programs out there that can do this on SIM cards on systems that write the text messages to the sSIM card, but it is my understanding that messages are not stored on the SIM card but in RAM.
Can any high level technical Palm programmer shed some light on this for me and let me know if there is a way to recovery deleted Text Messages on a Palm Centro?
Much Apreciated,
Greg

I had the same problem.
1.Search for a program call filez.prc (give your address I can send you) copy it to a memorycard. btw [email protected]
2. Copy it to the palm device(it works on any) activate the program on the palm chk rom at the top and chk all message database and smstxt and also some have 0000behind em. note the sizes as the older ones are larger and copy them to the card.
3. to view em use microsoft word and use recover txt from any file I think it is called. You will be able to see detail but be careful as it sometime displays truncated or mixed but you will be able to see most txt clearly.

Has 4 year old palm centro unlocked phone. want to change its panel+keypad.where to get it in india?

My phone became little old. Its of whilte pearl colour.
How can I change the case+keypad etc of this?
Where in India should be done this? Please help?
Or any option to upgrade to any other HP/PALM phone, in exchange of my this phone?
I am ready to pay any extra cost in exchange...

Hello smilekapoor, Palm Inc. ceased making new phones many years ago, and I'm afraid HP no longer supports them.
However, if you google "palm centro repair" you will find many places that still offer parts for your phone.
I do not know if any offer service to India; this will require some research on your part.
HTH,

Palm Centro GSM Unlocked freezing issues still unresolved?

Hi, I'm one of the many many (yes, we exist and we ARE MANY, even if Palm keeps ignoring us) unhappy Centro owners that purchased a smartphone that (ironically) doesn't work as a phone... I'm writing from Mexico and I bought a Palm Centro with Telcel.
I don't think it's necessary to again describe the problem because it's been discussed a lot here and in other respected and popular Treo/PDA forums... just google "Centro freeze" and you'll see for yourself.
I just wanted to know a couple of things:
1.Is Palm ever going to adress this issue as an official bug and offer a ROM/Firmware update solution or are they cowardly going to turn they're backs on us?
2. Has anyone suffering from this issue tried the custom ROM update offered by some guy at TreoCentral and did it work?
3. Flashing and/or changing the ROM of my quasi-phone voids warranty?
I hope someone can help us, the once satisfied and loyal Palm users now turned into desperate postin/ranting machines...

Can't send e-mails using Versamail 4.0.1 form my Palm Centro (unlocked - from ATT - on Rogers network).

Good afternoon. I am using a Palm Centro I just bought (unlocked - from ATT - on Rogers network). All is working great BUT sending e-mails. Versamail is receiving just fine but refuses to send. It puts everything I try to send into the "outbox" and then tries to send only to later tell me that it unable to send. The server I go through is a POP server. It has never given me such an issue before - Any advice!!

Hello!
With POP/IMAP email, there are 2 server. One is incomming to whihc ur ok and the other is outgoing to which that one is not. Since you are using Rogers for service, use the SMTP server from them to which I do belive is still smtp.rogerswirelessdata.com for the outgoing mail server.
Even though the phone has been unlocked, the phone design is still ATT so the versamail application is probably still using ATT's SMTP by default and you need to make the manual change.

How to set "from" field in Versamail 4.0.1 EAS / Palm Centro Verizon

I have set up a Palm Centro to sync via Activesync using Versamail 4.01.00. All seems to be working normally but there doesn't seem to be a place to set the senders proper first and last name as the sender. When I send an outbound message the recipient receives the message from login "username" instead of "Firstname Lastname". Anyone know where to change this?
Thanks,
