You can't without soldering RF amplifiers from a G1 to handle t-Mobile UMTS frequences.

Actually editing the Radio ROM would do so. I contacted jockyw2001 awhile ago about doing so and he said that there are no tools currently available for us to edit the chipset microcode in order to do so, even though the rest of the process is supposedly easy.

what ROM have you

Unlocking SonyEricsson SO903i

My girlfriend came back from Japan a few months ago and while she was there she bought a cell phone. This is partially my fault since I told her that if it had a SIM it could be unlocked and used in the US. Mostly true, right?
The problem is she went and bought a brand new phone that was recently released in Japan and I cant find a way to unlock it.
Does anyone know how to unlock this phone? Is there something specific I could use for SonyEricsson or is there a general unlock?
Its branded NTTDoCoMo FOMA. Its a sick phone, I just wish she could use it here.
Any help would be great.
Thanks in advance
Is Sony using WM?
OK when she got the phone did she ask for it to be enabled for roaming?
Have you asked the provider to unlock the phone for you?
The provider will ususally do one or the other.
If you are looking for a software solution you've come to the wrong place.
Its a Quad Band phone so it should work here. I'm not sure I understand why it would have to be roaming enabled. We dont want to roam, that would be expensive; we want to unlock it and use it with T-mobile.
Japanese providers will not assist you in any way to unlock a phone, its almost taboo to ask. When I was in Japan I asked how I could use a GSM Quad Band in the US and all they would say is it cant be done. Untrue because I know people who have Japanese phones in the US.
I'm not looking for a software solution, but if anyone knows where I could find software that might help that would be cool. I'm just wondering if anyone knows how to unlock this phone or knows how to unlock any SonyEricsson as it might be similar.
And are you asking if Sony is using Windows Mobile? If so, no they aren't. Are these forums only for WM?
My fault.
Upon further research I answered my own question.
It's actually not a GSM phone as I initially thought. Its a CDMA phone that uses a UIM card that is identical to a SIM card.
Solved
This is a GSM phone u can find IMEI number INa CDMA set u get ESN number not IMEI this phone is a GSM brand phone working on some other frequency. This can be unlocked using T-Sim but can't get network in your country.

m8x problems with signal (no 4g/lte, all others work)

hello everybody, i have a friend in chile with a problem, he does not speak nor writes English very well so on his behalf i am asking for some help.
he bough an unlocked international version of the phone, for some reason down in chile carriers carry all the latest but the m8, crazy right? anyhow, he made 100%sure the bands where the appropriate for his carrier, but the problem he has is that he does not get lte or 4g, get's everything else but 4g/lte. We have tried all the obvious steps, we made sure the phone was searching for 4g/lte, changed the apn, even went to the carrier and explained that he bought the phone, it has the correct bands etc, and he got told "well too bad is you didn't buy that through us". weird thing is, that he had a m7 that he also got in the same way, and it worked flawlessly. So here we are out of ideas on what it could be, and what we could do.
here's an image of his bootloader in case it can be useful ( cid is htc_621)
https://dl.dropboxusercontent.com/u/86252213/Pictures/One m8 Gold/IMG_4260.JPG
anyway, we where thinking that maybe rooting, s-off and sub-sequentially installing a custom rom would help?
anyhow, if you guys need any other info, please let me know and ill be happy to provide it, and thank you in advance for any help!
Try changing the band with this command: *#*#4636#*#*
I JUST did with my M7. Using Entel!

Help flashing t-mobile firmware to SM-G9600 (international unlocked)

Hi all,
I recently purchased a galaxy s9, model SM-G9600. I have never flashed a phone before so I'm quite new to this all. The problem with this phone is that it has no wifi-calling option in the settings. I currently have my t-mobile sim card in it. I've tried looking all over for an outside solution to this or if it is possible to just flash the proper t-mobile firmware to be able to get the wifi-calling option in the phone. I cannot seem to find a concrete answer/directions as to how to solve this. I was wondering if anyone could help me find a concrete answer and/or point me in the right direction.
Thank you in advance!
Hiya bud. Well the answer I'm gonna give is one you probably won't enjoy much, but no one else responded sadly.
I'm pretty sure that the wifi calling option will only work if you're on the correct calling network (I believe only tmobile branded for that software ).
I could be wrong though and the calling may work for other carriera, but I just thought I'd warm though ahead of time on your quest for the holy grail in case anyways.. If things work out better for you, then definitely let us know!
Cheers bud!!
Did you get it to work?

I have the same model and am on the t-mobile network. Did you flash your phone with the t-mobile firmware?? If so, did it work??
Thanks!

LG WING (LGU+) - NO USIM DETECTED

Hey guys,
Quick question. I am in Australia and bought a LGU+ (LMF100N) from Korea. The phone cannot detect any SIM and I cannot have access to the TEST FIELD menu, I have tried all compatible ROM, still impossible to activate DATA, add APN or have a SIM detected. Do you think it is software or hardware?
Please note that that it is not a DEMO LG Wing and it is unlocked. I have a 'NO USIM DETCTED' message so it is not even ask for a unlock code etc.
I have tried everything with no success.
Thanks hips for your help, advice and answers guys.
PS: congrats for all the posts explaining how to use software to patch etc. XDA forum is really really good. Still looking for the Discord LG WING. Do not hesitate to share the invoice with me.

I have seen quit a few LG Wings on Ebay with the sim slot being bad so it wouldn't surprise me.The good thing is,it pops in and out once you pull the back off.No soldering required!
@surgemanx sorry for the long delay mate but you were totally right. My problem was indeed the sim slot, I think i refused to admit it could be hardware as most of the time it is software. I returned it and bought a new WING (US version this time) and it was all good I spent hours install rom etc for nothing lol at least I know how to do it now. Just waiting for Android 12
Very happy of the phone otherwise. Thanks again for your answer.

LG G8 (LM-G820UMB) for Verizon US unlocked - problem while using in UK/Europe

Hi all
I've spent last hour to try find answer for my problem in xda forum, without success. I hope that someone could shed more light and then I will know where to dig in (maybe ROMs, kernels etc)
I don't want to put this thread in general questions about LG G8, as I have feeling that if there is a solution it will be in this subject.
I just received my phone today (ordered via ebay from China) and 1st impression was that it's locked as information appeared "SIM card in not from Verizon Wireless" and there was no network conenction. However after digging and contacting Verizon directly I got confirmation that phone is unlocked.
In the meantime I've noticed that it gets some very weak signal now and then. After some more digging I get to conclusion that this version of the phone is not comaptybile with band frequencies here in UK.
Can someone tell me if this is the issue and if there is a solution for it? Is it software thing or hardware and I can forget about using this phone normally?
Details of the phone:
Andriod: 10
Soft version: G820UM20j
Model number: LM-G820UM, this is from phone settings, but I think it should be "B" at the end for Verizon?!
Thank you in advance for sharing your thoughts.
Kind Regards
Tom
