Is it 900MHz or 900/1800MHz

[mma]

Gents,

I have been following this forum for about 9 months now; it is a great place to visit if one has an XDA – which I do.

I have one question, I upgraded my Qtek1010 to rom ver: 4.00.21 ENG (from yorch.net), it gives an option to select band 900 (Europe) or 1900 (North America). Does 900 really mean 900 or does represent 900/1800 (Europe), i.e. can my mobile still hand over call to cells on 1800MHz in Saudi or is it limited to the 900MHz band as a result of this upgrade?

Thanks for your help

it should be 900/1800 i think

i seem to recall that EU were at first 900
and asia were 1800
and us were 1900

then dual bandphones came and
you could get
900/1800
and
900/1900

not sure about 1800/1900

so it should work on both 900 and 1800 because the phone is dual

I dont think the upgrade changes the hardware capability, the phone will be 900/1800 or 900/1900, the latter can only be used in UK/europe on the 900 band, the 1800 is not achievable as far as I know.

yes 900,hz means 900 only which means if you have been into the band tab in the phone options your device will now be stuck at 900mhz only meaing you have lost the 1800band.....

and 1900 wont work it wil lcause your phone to freeze/no signal.

what you should do is go into your bootloader and achange it to 900/1800 and do not touch the band tab again becuase if you do you will have to select either 900 or 1900

this is because you are using an american rom.....

use v4.00.05 or v4.00.11 they are english roms with 1800/900 :)

Hi ...

The siginifact point is the device h/w type ... is it PW10A1 or PW10B ?? ... refer to the sticker on the rear side of the XDA.

In case it's A then it supports only 900/1800 and the 900 option will mean 900/1800 and the GSM menu should be adjusted to the right band ... if it's B then it's 900/1900 and you can only use the 900 MHz band of your network coz the H/W doesn't support 1800 MHz

Either the GSM menu or the Band tab has no effect if the H/W doesn't support 1800 MHz

Folks,

Thanks for your help, I guess until I downgrade to 4.00.11 ENG I will use the bootloader to set it to 900/1800 and stay away from the band tab.

Thanks again

[gazzaman2k]

you can use any version you want mate but if using an american rom like what i am at the mo (v4.01.00) just dont click on the band tab under the phone options as once you do theres no way to close that screen without select either 900 or 1900 :(

if you do select either band just go into the bootloader and put it on 900/1800 again and dont touch the band tab :) that way you will still have your 1800 mhz band too :)

soft reset will solve the problem :lol:

[gazzaman2k]

lol yeah that also but why not try avoiding the band tab once and for all lol that way you wont have to reset the bootloader bit or reset it if you go into the tab lol

gazzaman2k,

You recommanded using 4.00.05 or 4.00.11, I found 4.00.05 in yorch.net, do you know were I can get 4.00.11? I'm assuming it is a better rom!

Thanks for your help

[gazzaman2k]

searche the forum for it mate youll find it :) v4.00.11 uncooked :)

[Biso007]

The only place for 4.00.11 was Jiff kitchen but it's down now :(

The ROM part of TMO 4.01.00 is not bad at all ... I have it since 2 months now and it's so stable ... didn't try it with SD cards tho

you may consider this upgrade ... again, the ROM part only :)
