Having done the Anansky upgrade, my model number reverted to PM10A... which is the 900MHz version of the Magician.
I know that this doesn't prevent a physical PM10C from accessing 850MHz towers, but I'd still like to change it to the proper model number for ease of upgrading and stuff.
Is this possible?

hello:
i know that this topic has been addressed, but it's not clear what the answer is:
i have a friend that bought the "b" model xda (900/1900) in the united states, and took it to brasil. he ran XDAunlock, and the sim is unlocked.
with bootloader, he told the phone to operate at 900/1800. the program
"bandswitcher" or something that's included in the xda developer's rom
indicates that the phone is at 900/1800.
but it gets no signal using sim cards in sao paolo, brasil.
many posters have indicated that they do get some connectivity,
not quite what a native 900/1800 would get, but much better than nothing.
other posters have said that it is not possible to get any signal, since there is a hardware difference that can't be compensated for with software.
who is right? is there anyone from brazil that has gotten a 900/1900 phone to work that could tell me how they did it, what city they're in, and what provider they use?
if it's true there is a hardware difference, is there a user-friendly way to swap out some internal part to make the bandwidth change?
any firm answers appreciated; if you are only guessing (like assuming that since wallaby bootloader mentions switching bandwidth, it's therefore possible), then please say so. i'd really like to know for sure what the story is.
thanks guys!
The 900/1900 gsm phone was never intended to work at 1800, some people manage to get signal but there are many factors involved such as proximity to mast, the fact is you are trying to use it off tune, try listening to a radio station 100mhz away from the advertised frequency and see how it sounds, if you were right next to the transmitter you would probably hear it because it would break through on to adjacent bands, but go further away and the discrepancy would become more obvious. If you need to work on 1800 get another phone or sell it and get the correct model.
hi,
let ur friend ask the operator there if they have 900 MHz signal. if yes, then all he has to do is to select this band on both GSM menu at the bootloader and in the phone settings.
good luck
I recently got a locked SX56 loaded with the 2003 ROM. To unlock it, I flashed it with the SER and it's working fine now. But I'd like to go back to the 2003 ROM yet keep my phone unlocked.
Before flashing I had backed up the 2003 ROM using XDATools, can i reflash that image into the sx56? Would this keep my phone unlocked? OR do I need to download the 2003 ROM from the Siemens website (really do not want to dl 18 mb!).
Any help is highly appreciated.
Thanks
Omi
You can reflash your backup version. The phone will be unlocked after upfrading...

not able to change bands
Thanks LumpiStefan for your reply, I hope you could also help me with another problem that I'm facing with my XDA.
After changing to the SER, I wanted to switch bands also to 900/1800 but when the I start the band selector tool it gives an ERROR everytime and I'm not able to change bands. It works fine with the operators on 900Mhz but unfortunatley the operator who provides at 1800Mhz is much cheaper and also provides cheap GPRS services here. I'd really like to try the phone on 1800Mhz to see if it would be possible to use the phone with that operator.
Would changing to WM2003 help me change bands easier?
Thanks
Omitav
It all depends on the device type ... only PW10A devices work with 900/1800 (check the rear sticker) ... also the RSU must be suitable for 900/1800 or you may endup killing the device!
Hi Biso007
I've read in the forum that several ppl have changed bands in their PW10Bs and been able to receive 1800 operators (altough the signal strength was usually bad). I wanted to try that out.
How do I find out if my RSU supports 1800 Mhz?
The device info mentions that my Radio is A.33.02, can (and should this) be upgraded?
Thanks for your help.

I think you mean that some B devices worked on 1800 operator network and this can be true if the operator supports 900 as well (usually they are) and that's exactly my case.
I don't think B device with 900/1900 RSU like yours can work on pure 1800 MHz network ... or what is the need for the expensive tri-band XDA II then :wink:
Right, I got it
Yep, mine works fine with the first 3 operators in the state (since they're all on 900). It only won't work with the 4th operator (hutch) as they're on 1800.
Can't have everything I guess :-(
Hutch provides really affordable GPRS, gonna miss that. The other operator provides GPRS at exhorbitant rates, will have to wait until some operator gives at a cheaper rate.
BTW, where r u located in India ?

are the frequencies hardware bound or software bound??
i read that on the typhoon, depending on which rom you flashed, it will change from 900mhz to 850mhz, or vise versa. is this a possibility with the magician platform?
perhaps i should have been clear.
with the magician, we have a tri-band phone. most of them are 900/1800/1900mhz and US models have 850/1800/1900mhz.
with the typhoon, i read that the device is quadband capable, but only three bands are enabled at once. so you can get a audiovox smt5600, which has 850/1800/1900mhz, and flash a c500 rom to it and you will end up with a 900/1800/1900mhz device.
i always thought that the frequencies are dependent on hardware settings, but i guess there is more to it than that.
so what i am asking is, is it possible to get a lets say, qtek s100 and flash it with i-mate jam US version rom, than will it enable the 850mhz band and disable 900mhz band?
i didn't think this was so much a stupid questions....
enlighten me!
I remeber reading a thread on Modaco or Hofo a month ago about this issue. Try to search there and see if you can find the thread. The general result was that you can flash a 850 Rom on a 900 Magician and the 850 will work, the 900 will be disabled. There were a few posts there of members who confirmed it worked. However, because the radio part was designed for the 900 band, the slight change in frequencies can over time damage your radio and make it useless. So be carefull to try this. read the mentioned fora for more info.
As far as I am aware the 850/900 difference is in the radio hardware and cannot be changed in software.
Hi,
this is the first time im working with with pdas so im totally new in this area. I bought one i-mate Jam and im using ok with one card provider, yesterday i change for other provider and i dont understand why my pda cant get network with this new provider.. i try to make a manual search and no information. the pda is brand new and i also contact the provider to see if is not barred and all is 100% ok... can someone knows if this can be fixed or have any ideia about this?
regards
For sure your unit is SIM locked. There are threads on how to unlock. Please do a search.
the pda is not locked becouse acept card without any problems... the only problem is dont get network of one provider.
What are OS ROM and Radio ROM versions in your unit? If it's an old one try to upgrade to the latest. There are a number of ROM's available in the FTP
Try your new SIM in other phones and see if it works ok. Also try borrowing from friends SIM of the same provider as your new SIM as well as SIMs from other providers.
The magician is a tri-band device build in two flavors:
- 850, 1800, 1900mHz
- 900, 1800, 1900mHz
Could it be the one provider which doesn't work is operating on a non-supported band?

hi,
i flash this pda few hours ago and i still have the same problem.. i was looking in other sites and i found something about this problem.
Exact this models have to versions:
PM10A (900-1800-1900 mhz) and PM10C (850-1800-1900mhz) and the one that i have is PM10C. I have to find one way to convert it to PM10A so then i will be able to fix this problem.
When you find the way to change a PM10C to a PM10A or vice-versa you're the man! It's hardware specific & not build in the rom :-(
M
i know someone that can make this change but dont share with no one... i cant do a lot becouse i have only PM10c in hands and i dont have any PM10A to compare the boards.
I just did a search with the keyword "850" and there are 2 pages of threads about this. All threads confirm what what OLTP mentioned - the radio frequencies are set via hardware components and no software or hack can change it. In fact, "Reo" mentioned that he modified the hardware of his unit to make it into a 900/1800/1900 MHz unit.
The 850 and 1900 MHz frequencies are used in the USA, while the 900 and 1800 MHz frequencies are used in Asia, Australia and Europe. I'm pretty sure that your new SIM supports only the 900 MHz frequency. Ask your current provider or check their website to find out what frequency they use. If your provider supports only the 900 MHz, then your last resort is to change provider again.
Hi all,
Sorry if this sounds daft, but I have just been given the tech assult by a Telstra Australia guy.
Telstra uses a "Next G" network that used 850MHz and will state that ONLY phones bought through them will be able to fully utilise the network. Is this a firmware thing (IE, can I flash the radio rom) or a hardware thing? If I bought a device from anywhere else would I be able to utilise the speed of the "Next G" network? If not, what features would we be missing?
Cheers
Al
Frequncies is a hardware thing
some phones support that band as it's also used in usa you can check the wiki for the phone in question
if you have a quad band phone with 850 MHz, it should work ontelestra, the only features that might not work on it are features that have been cooked into the rom. Phone and generic features will work as the are standard to all hardware types.
If your phone is 3g capable, yes you will be able to use their updated 3g as the attachment to allow their network to work on your phone will be on a telstra sim card.
