I´ve a pocket pc SX_56 bought in USA, e-bay.
This is one PW10B1 (serieal number in the back of device)
But the ROM says PW10A1.
I try use it in Brazil, but i can´t, it´s lock.
The system don´t cach the signal.
Then i try upgrade the ROM (xda-developers.com) and now the device is unlock,
but don´t recognize the signal.
What´s the best solucion? If i upgrade the sistem will it work?
Thank´s.
Best regards
ps. Will it force-upgrade my radio stack?
I presume this is for US market. So it will be on 1900.
Its shown on the website that it can be "Auto band selection when traveling overseas", so does I can use the 900/1800 band when in Brazil(my country)?
You can enter bootloader and choose 900/1800 but you might have little success, the xda is a dual band phone 900/1900 or 900/1800 not triband.

Then it's a PW10B device (900/1900 MHz) .. forget what's written in device info.
Check with your operator which band width to use and use the GSM menu in the bootloader accordingly.
How do you get to the bootloader?
I know, it's a silly question, but I'd like to see what band width I am on.
Thanks

unfortunately, I 'm not aware of an accurate way to 100% positively determin this. Only in TMO 4.01.00 ROM there is a band selector in the phone settings but I can't trust it that much.
Usually people get the right band from the operator and select it from the GSM menu which has no indicator for what is the current band.
Maybe it's something to be added to the wishlist of WM2004 :wink:

Hi All,
I have an unlocked SX56 device on which I have installed xda-dev ROM w/ WM2003SE (version 4.20.0) and is working properly here in USA on Cingular.
I recently went to India and hoped that it would automatically work there on band 900 but to my surprise it didn't. I tried a local simcard there but it always said no service.
I did some research and found out about bandswitch tool.
I copied it on to the device but when I click it shows ERROR for the current band and nothing happens when I click on either 900 or 900/1800 or 1900.
I am going to India again in few weeks and am wondering if there's something else I can do to make it work?
Thanks in advance.
-D
here is some more info about the device.
code on the back: PW10B1
ROM version: A.30.09 ENG
Radio version: M.E1.19
Protocol version: 324e4
Hey bud!
Unfortunately... you will have to get into the bootloader and manually switch bands.
It will work.
Also which service provider did you use when you were in India? and in what location?
Lemme know if you face any issues.
cheers!

Sorry to post T-01C question in TG01 forum. This Android phone is from NTT Docomo , and in China we use a cracked SIM sticker ( Mr SIM ) to cheat the network so as to make phone calls. But today I accidently chose the Radio Band GSM/UMTS as USA band, now I cannot switch it back and lost and network connection. I know you guys have been using T-01C’s Android Kernel to develop TG01’s Android Rom, could anyone give me some suggestion how to get the right Radio back? When the radio is on there is only one option US band to select; if radio is off, there are more options like AU , JAPAN band etc., but no matter which one I choose, just cannot set it successfully even the system is rooted.
T-01C have been updated in May from OS 2.1 to 2.2 while Radio from 5011.1906.50 to 5014.1906.11. Now I download the 2.2 ROM from official website and try to use T01C_SWUpdater01.apk to flash, it fails because I already use the latest OS.
Could anyone help me on this? Thanks for reading!
Hi everyone,
I have the LG Optimus L90 D415 from T-mobile. I'm in Europe using a different carrier and I can only connect to 2G (EDGE). Following the instructions I found, I configured properly the APN and tried to change the radio to "Euro band" from the *#*#4636#*#* menu but when I press the option "Select radio band" I don't have any options to choose, just the title "Set GSM/UMTS band".
I didn't find any custom ROM to check if it changes. Can you please help me?
Thank you in advance.
It may be under the menu found via 3845#*415# ,
Theres radio settings to enable band 2100. Not sure if it will work without a new anntena in your phone. Tmobile US do not use full 2100 band but a cdma subset.
Failing that i think your wasting your time with roms. Try updating the firmware for your anntena. Perhaps the firmware from the 405 model but update firmeware with cation
Did u get it working ?

After enabled is it possible disable it?
hi
Did it work?
The T-Mobile version of the phone does not support UMTS (3g) on band 1 for the 2100 Mhz frequency as many European and other countries use, so that's most likely why there aren't any options, because nothing you could change would make a difference.

Any solution for enabling WCDMA 2100 band 1 on LG-D415 ?

Hi, I need help.
So, I bought 2 moto E 2015 model (at&t unlocked) from Ebay - very cheap.
But this phones working with only 2G mode in my country (even theese are LTE models ).
I want to reinstall system to better one - which there is no any at&t default applications or any of carrier applications.
And I also want to change baseband versions - because, this phone working only with 2G network type with my country's mobile carriers. I think it should be for baseband (network standarts) .
is it possible to fix problem with change firmware and baseband to no-contract version?
I asked my mobile carrier, they said, "we are using 900-1800 MHZ for GSM ; 900-2100 for 3G, 2100 for LTE (up to 2100)
Who can provide how to and links?
Thanks.
The AT&T model cannot be bootloader unlocked, so you cannot change the firmware to another version. There's a guide in the General forum about enabling additional LTE bands, you can try tweaking it for 3G, but there's no guarantee that the AT&T model's antenna hardware can support those bands.
