[Q] LP500 on US T-Mobile - Optimus One, P500, V General

I have T-Mobile service in the US. The phone that I got originally from T-Mobile was an LGP509 with the V10s baseband. I flashed the new baseband (V20g) and it always worked fine for calls, 2g, and 3g. That one died a slow and painful death, so I went to Amazon.com and bought an actual unbranded LGP500. This one came with GB and the P500-M76XX-V20g-SEP-21-2011-XX baseband. The problem is that 3g has never worked on this phone since I got it, even though 2g works fine(but slowly). I noticed that the Baseband was a little different from the the one I installed on the old P509 ( which had a JUN-14-2011 date in the name), so I flashed the V20g JUN-14-2011 basband hoping to restore 3g. Successful flash, but still no 3g. Anyone have any ideas about how to fix this? Is it safe to flash the p509 V10s (old Baseband) to a p500 to see if that works?
I guess my question is this: Is there ANY hardware difference between the p500 and p509 that would prevent the p500 from working on T-Mobile's 3g network? AFAIK, the differences are in the radio firmware (baseband). Am I wrong?
Any help is much appreciated.
Forgive me if this is addressed anywhere else. For the life of me I couldn't find posts about anyone who as a p500 and wants to flash a p509 v10s baseband to it.

I dont think p500 will work on tmobile 3g
because optimus t is p509 with 1700 aws band

Thank you, you are absolutely right. I've been researching this issue today, and I'll share what I've found in case anyone else is interested/cares.
I got my hands on the elusive p509 service manual today. I've been comparing it to the more common p500 service manual. It looks like the two share a common PCB, but there are vacant sections of each phone's PCB which are populated on the other. These sections are essentially filters for the radio signals coming in and going out through the antenna.
The phone's software just selects the WCDMA antenna and whatever filters are in place determine which band is used.
I had originally thought that the capability was available in every p50x phone, but that it was selected based on available networks. I assumed wrong.

How to get 3G on an European Hero.

I heard its possible to flash the radio so it match the US and Canada frequencies to get 3G data instead of EDGE
Can someone Help me. I found a link to the Radio roms but no step by step flashing guide.
I have a european Hero Downgraded to version 2.73.405.5 on Baseband version 63.18.55.06EU_6.35.06.18.
How can I make it work on 3G cause right now I can only acces EDGE. With ROGERS Canada
Thanks to all of you guys (& girls) because this is new to me and seriously, some of you are really talented.
seriously dude, that has been asked several times, is not possible and belongs not in this category.
OK man sorry about that was not there for the past years reading all the threads ever created... I did some search and wasnt able to find specific guide about that...
Forget about it and have a nice day.
i recently read that it is possible on some winmo phones to use the radio matching your network on a different phone. comes with the downside that reception goes down to (i would think) unusable level, because the hardware is not meant to work on these frequencies. it is more of a "side effect" that it works at all. i have not read of something like this happening at all for a hero.

T-Mobile to telus?

I've been having signal issues with my unlocked tmobile vibrant here in canada. I have telus signal in city (3g i assume) once i go out to the county i got nothing on my phone... i can see other providers just not telus.... and my friends who have telus iphones etc have 4 bars +.
After reading this http://forum.xda-developers.com/showthread.php?t=923712
Assuming the OP is correct in that the fascinate and vibrant are almost identical... would it be possible to switch the modem to solve my signal reception issues?
Thanks
** i've contacted telus and they dont have any answers for me... the phone cleared their online compatibility checker and im on my second SIM.
Any follow-up on this? Im on Wind right now with my T959, might have to switch providers... from what I understood the T959 does NOT use the same bands, so I'm wondering if that's your problem, and possibly my future one... let me know
I have the latest radio from Telus T959TKG2 and runs like a charm

Photon Baseband Switcher Enabler.APK For All US GSM Networks

Just wondering if anyone has seen or tried to develop a baseband switcher application like the one found here http://forum.xda-developers.com/showthread.php?t=1203297 so the Photon can work on all US/international CDMA/GSM networks?? Out of the box it has(CDMA 850/1900-GSM 850/900/1800/1900-WCDMA 850/1900/2100-Wimax 2500).. but no 1700 T-MO..I have a Photon but no use for it since im using T-Mobile..Perhaps unlocking and a baseband switcher would enable me to use this amazing phone on any US GSM network like my Moto Defy Ive been using this app and Itfunz for international travel and im amazed how well my phone works on almost every GSM band in the US and around the globe.....Anyone?? This Phone with Root,CM7 and a "working" baseband switcher would be untouchable!!
Im on sprint so no real need for the switcher but i would love to see this come to life. I can make my brother jealous and steal his sim card.
I would love that
I am in the Dominican Republic and have not been able to find any alternative baseband versions to flash, since 3G (850 Mhz Band) stopped working a few days ago.
I´ve reflashed to stock, tried different roms and kernels, but i guess if i can swith the baseband version it might work again.
This app would be awesome, anyone tried it on the photon yet?
Any News On This?
I tryied it - doens help me.... I created activity which is switch's baseband and turn it to USA gms baseband.... I lost connection :-((( and can't repair it :-((((
please help :-((( baseband switcher says "your baseband setting are incorrect. would you like to reset it to defaults?". I answer Yes and it reboots with old settings and don't work :-(
maybe somebody knows a way to reset baseband settings?

what sbf stands for? I just bought the phone and my reason to buy it was the sim card ability I would like to use it on my trips to Mexico and I would very much love to be able to nuy a sim card from a Mex. carrier and use that way.
I believe you can. I forget the post where somebody gave the name of the sim card they used...
You may need to contact Sprint to get international use activated, I believe at no charge.

new baseband on t-mobile US

Would someone point me in the right direction or explain why the new baseband has problems on t-mobiles US network?
I have been searching and cannot find very much.
Thanks in advance.

If I may elaborate on what Jrhodes85 was saying:
With the new baseband, the 1700Mhz band (which accounts for half of T-mobile's HSDPA coverage in the US, among other carriers) is completely unstable, if not non-existent.
Most international carriers' data works great, but O1 users in North America and possibly a couple other regions are slowly getting pushed into obsolescence.

So does this mean that T-Mobiles network is using a frequency hardly anybody uses which also means future ROMs which are build upon the new baseband?
I am not with T-Mobile USA because I am also German but because I feel they are the only company which uses GSM smartphones and has reasonable prices for data and voice.
ATT Sprint and Verizon in my opinion are drastically overpriced for they bad product they deliver and MetroPCS or BoostMobile seem to have questionable reputation when it comes to service quality.
What would this mean for our future with T-Mobile?
What do they do with new smartphones? They also use the old baseband?

The baseband is just the software that controls the phone's radio systems. It so happens that the baseband released in Europe apparently does not support the 1700 mhz part of the spectrum that carriers like T-Mobile broadcasts their signal on. I highly doubt that LG is passing on supporting an entire frequency range, as that would be a terrible business decision considering there are more carriers than just T-Mobile using it.
The spectrum T-mobile broadcasts on has other issues (no clear roadmap to 4G, etc), but you won't need to really worry about that for years.
To the OP: How does this manifest? Well, after flashing the new baseband, my data speeds have slowed down considerably. Google Music is now unusable, yet I am still able to make voice calls and send texts. I am not on T-Mobile, but I am using an Optimus T on WIND here in Canada.
Thanks for the responses.
The other day I briefly switched to the new baseband. One thing I noticed was that I had 3G in my office whereas before I did not, I don't know why, but I didn't notice any really problems. Only after reading a few things that others were saying I decided to go back to the old baseband.
What do the new tmobile phones have for a baseband? If they are on gingerbread are they on the new baseband? How does that work?
well I have a 30 MB dataplan hahah so I can somewhat not care about G3.
I mainly use it for Google Maps sometimes and thats it.
I am to cheap to pay more than 30 Dollars for such services. If they would charge 5 dollars for 500 MB ror so I would do it.
Well I hope that the baseband modem drivers for the LG Optimus at one point can support both frequencies as I just learned that this
is a driver option.
The German iPhone can be made to work in the USA when you just hack into the phone and activate the frequency used in the USA.
Tmobile isn't really anything compared to AT&T or Verizon, they honestly have far superior phones...in the days of the g1 which ran specifically on tmobile usa was easy to switch radio...back than it was Radio SPL and was as simple installing as flashing any rom or kernel...my question was simple....
Can tmobile users in the US have new baseband that provides working mobile data (3g/2g)..because without it working, the phones practically useless without wifi

Unless someone is able to merge that portion of the old baseband with the new baseband, I sincerely doubt we're going to see this resolved.
T-Mobile seems to have no interest in pushing LG to update the Optimus T to Gingerbread. Either that, or they're waiting to improve the adoption rate of Gingerbread on the G2X before they bother with older phones (horrible logic, if you ask me).
I hate to say it, but there may need to be somewhat of a divide among developers if certain roms can't be built for both basebands. Of course, this isn't anything new for the Optimus line. The Optimus V is all on its own, too.

Well i know that on the openoptimus ROM new Baseband 3g works fine but not on the other ROMs thats why i thought it was a apn issue but i never got a chance to check cause i bricked mine going back to the v10 baseband and got a new p509 from warranty, and as far as tmobile update i highly doubt it because i know someone that works for tmobile and he said they are phasing the phone out they are not even on the shelf at most stores i wish some one would just let us know is it just the apn setting cause we can put those in manually here (I have a link if anyone needs how to do that PM me) i just gave my P509 to my girlfriend so i dont want to try and then have her not have data when she gets a new phone i will try but not right now
so based on what you say
the new openoptimus rom once stable and running fine on the Optimus T would allow full access to 3G ???
I bricked my phone wanted to do a replacement and the guy on the phone at T-Mobile told me they dont because they dont support it anymore.
So I guess you are pretty right with your assumption.
Fortunately I was able to recover it on my own.

Pretty much and art this point I'm not sure it's worth the risk she should get a new phone in a few weeks I will test everything after that

That is just sad.....about tmobile phasing the OpT out, its one of the best entry level smartphone they provide,even when I walk into to pay my bill I still see people buying the OpT....that's why I enjoy devs like andy and bytecode, they're all developing with old baseband

I agree - if the camera would be better I would more than happy with this phone and not need more.
Yea its a good phone I loved my Optimus and in fact still do I mod it for my girlfriend now for fun but I will tell you going from the Optimus to this phone (HTC Sensation) is amazing I love this phone and if you are going to upgrade it is a great phone, granted the Tmobile gs2 had more storage and a better processor (there is really no difference) the development in the Tmobile version of the galaxy s2 is slow and week as hell almost all themed ROMs while mine has great ROMS full working ICS ROMs both with HTC Sence 3.5 and stock ICS ROMs as well as official support for cyanogen mod and Miui which the Tmobile GS2 doesn't have just a little tip to my fellow Tmobile users .....anyway back on topic I'm pretty sure we can get the new baseband cyanogen mod working on our Optimus t and I will figure out how as soon as I get my girl another phone

I am almost certain that will not be the case. Android developers, while talented, are not electrical engineers and developing firmware to run a 3G radio is far beyond their skill set. The only possibility is for LG to update with a new baseband that doesn't screw over Optimus T users.
all of these new baseband scares me now.
I am using the new baseband on Optimus T on Mobilicity network (1700)
is there a risk that I may bricked this phone?
I am using Adam's N1 CM7 , with V20G baseband
It works well for me and I love CM7

I dont think you can brick the phone just by flashing the baseband.
And the baseband discussion is an issue with the T-Mobile service in the USA as I think in Europe it works fine and I think Asia should be the same.
Does Indonesia use GSM or CDMA?

I don't think you ruined your phone. I had mine on the new baseband for a couple days and didn't have any problems. I reverted back to the old one and it has been just fine.
I have an Optimus One T too, but I bought it unlocked on eBay. My carrier uses 2100MHz for 3G where I live. So far I've had no problems with the old baseband. I'm using CM7.1 (mik_os 6.5.8) but would like to try adfad666's latest versions, which only support the new baseband. Do you guys think it would work?
I've got a lg-p509 optimus-t in the U.S., do I understand correctly that I'm on the old baseband since t-mo never did the official gb update for this phone?
When I check in "about phone" my baseband info is the seemingly meaningless "V07u-000-000-mar-23-2009" not v10 or v20g etc.
P.S. I'm running adfad666's cm-7.2.0-RCO-optimusone-kang with goldenleaf 2.6.32.9 #1 right now with no issues to speak of.
Update: I booted windows and installed the lg mobile support tool which seems to show I'm at v10s, which they want to update to 10L maybe??
"get info" button returns 10s and main lg tool window shows 10L below my phone model.
it says update available, but is kind of short on detail.

CDMA Android phone on LG U+ (Korean network), WiFi problems, caused by network?

Hi,
I'm in the UK and I work in the gadget repair industry. I have been asked to sort out an LG Optimus Big LU6800 that's having problems with the Wifi and Bluetooth. It's locked to a South Korean phone network called LG U+ (No Sim card)
After a couple of hours of research (which has been difficult given that there's not much English documentation or discussion on this phone) I think I've worked out that LG U+ have the phone locked down so that the WiFi and Bluetooth functionalities don't work unless you purchase a data plan with the network. I've also read that they blacklist the phone if the contract plan is terminated, also rendering Wifi and Bluetooth unusable. Is this even possible, or is this what they might have done?
Can anyone help me on this? Or can anyone fluent in Korean do some Googling on my behalf to find this out. I know it's not a hardware problem as I have already replaced the antenna to no avail. (this is my first experience with CDMA phones, I've never seen one before). I can't even boot the phone into developer mode, it seems like they've locked that down too .. meaning I don't actually know how I'm going to go around sorting this phone out.
Hopefully someone can help me, this seems like a good forum.
Thanks.
