[Q]L9 P768 cant connect to 3G or HSPA, only EDGE - LG Optimus L9 P760, P765, P768, P769

Hi
I purchased a Optimus L9 P768 lastweek, and i noted that it cant connect to 3G or HSPA network only edge, i bought it with android ICS 4.0.4 and first it said EDGE:2 then after the JB update its only EDGE, its hell slow, i inserted my sim card in another phone and can connect to 3G w/o problems, i checked and rechecked the APN and its fine, also tried *#*#4636#*#* and its on WCDMA Preffered if i try to change it i cant even do phone calls, it only works in that option, i been checking around and its probably my baseband i wonder if there any method to flash another one i got l6260_modem_sic_01.1230.00 probably my phone is european because the charge box comes by default with european plug i had to buy an adapter to use the charger, i live in Mexico, i hope someone can help me

MiniCM7Pro V21 Roaming Issues

Roaming doesnt work for some reason, but when switching Sim card to other cellphone, Roaming works.
I came to other country, phone connected to other network for a while and then it was just gone for no apearent reason. Trid to reboot, turn off turn on doesnt work. Glad i have other phone on wich sim card connects to the network.
Anyone expierienced this?
I think you should've post this on Q&A thread instead..
For me, haven't tested since I don't go outside my country at all..
hi,
i made about 30 countries and everything was working well.
from which country is your sim card/provider ?
thx
hi, provider is from Lithuania tele 2. yesterday I was in finland and phone got connected,but after some time connection was lost totaly and despite it was able to find other networks xperia waasnt able to connect. glad I had another phone SE w660,network with same sim card worked flawesly.
right now im in latvia and xperia was able to connect the network.
I imagine it must be some bug with rom because roaming works fine on other cellphone with sim card

Cannot connect to network

Hi guys, noob here, just got my first android phone (been with blackberry till now).
I got a chinese X12 dual sim phone because i really needed only 1 phone (had to carry around 2 of them).
Phone works great, only problem is with the mobile networks. It can connect to GSM networks but it won't connect to a 3G network. The phone has 3G capabilities, 3G is enabled for the required sim, it finds the 3G network but it will not connect to it.
Sim works fine, had it in a Samsung i900 on 3G (WCDMA) - i live in Europe.
The thing that surprises me most is that the phone came with android 4.0 instead of the 2.3.6 it was advertised, could this be the problem?
Data Enabled ?! have access points ?!

yes, data is enabled on it, as for the access points it has them too (althought i am only trying to connect to the voice network, not the data network)
Tried one more thing which is wierd: the phone works ok with another 3G sim from another provider, but with the other sim it doesn't connect (but it finds the actual network). And the sim that won't connect works on my old phone (the samsung i900)
The first sim that works on 3G on my new phone is from Vodafone (and they have both GSM and WCDMA in my country), while the other sim that doesn't work is from a provider that only has 3G (for both voice and data).
Quick update:
i found out i also get an "error" : invalid IMEI for both sims - it was this way when i first got the phone...
really strange thing with this phone, in settings > about > it says android version 4.0 but when it starts it has the honeycomb logo...
would appreciate any help, if it's from the missing imei's that would be good (or bad, depending on how hard is that to fix).
You can call ##778# to get into those settings. But be careful, those can really screw up your phone if your not careful.
The only reason i can think of, is if your phone only supports certain UMTS bands, while your operator is using different ones. Check out this article: http://en.wikipedia.org/wiki/UMTS_frequency_bands.
For example, my previous phone HTS Nexus One came in two versions - one for ATT(UMTS 850/1900/2100) and another for T-Mobile(UMTS AWS/900/2100). Both were GSM, both had 3G, but 3G would not work on another operator.

phone has only WCDMA 3G network - i tried it on different carriers (on 3G and not GSM) and it works fine, connects to 3G, it just won't connect to this specific network (although it finds the network there, so i guess it has the hardware to connect to it).
could this be from the lack of the IMEI ?
FIXED !!!!
Got it fixed, the problem was with the missing IMEI codes, put them back in, works like a charm.
I used the tutorial here:

NO Signal Icon

Long story short: i got this phone as replacement thought an cellphone unlock company that flash my original T-Mobile Vibrant SGH-T959 too many time and the phone crashed. Then after almost a year of going back in forward with them they apparently got a replacement phone from Samsung and I got this Galaxy II GT-I9100 and now I am back to square1.
The phone turn on fine and everything seems to be working OK till I insert my T-mobile SIM card and reboot the phone and all I get is the “No signal” icon on the upper right, I try my wife ATT SIM Card and the same, I check the network mode and set to auto, check Access Point Names and t shows epc.tmobile.com (green), If I go to the about phone status it shows “Unknown” under network, the phone never prompt to insert unlock network code or anything it just boots all the way, any feed back to get this phone to work will be very appreciated:
Samsung GT-I9100
No carrier specific
GB 2.3.4
PDA: I9100UHKI2
PHONE: I9100UHKI2
CSC: I9100UUBKI2
BIULD MON SEP 5 KST 2011

Try to flash the newest official firmware trough odin and see if this helps.

How can i find out if this phone was made to work for T-Mobile or USA i beleive that the reason the phone does nt find any network is becuase was not made for the USA.
I type on the dile pad to change the base band and there was an option for the USA but still the same issue.
please help!
i don;t think anything is wron wiht the phone it self.

The GT-I9100 wasn't designed for T-mobile USA, and even if you DID manage to get signal with it, you'll only receive Edge data speeds, as it lacks the capability to receive one of the necessary bands to get high speed data on T-mobile USA's network.
It does fully work and get high speed mobile data on ATT's network, however. (I'm in the states, using this phone on ATT)
Unfortunalety this particular phone does not work wiht ATT either.
I think i may have to just sell it on Ebay for part since i can even tell with what network this phone will work.

Sounds like it could be SIM locked to a particular carrier, or maybe there is a hardware issue with the antenna.
If the phone is sim card locked would the phone pormpt me to enter the code?
this phone does not prompt for anything whather is the ATT or the T-mobile sim card.
see video.

SIM locked to a network. Meaning only a SIM from a particular network will work. Not a SIM PIN.
EDIT to add: also check your IMEI. Is it 004999010640000 or something else? (DON'T post what it actually is if it is something else...)
ctomgee:
What baseband version does your I9100 has?
I have I9100UHLPE
My IMEI starts with 3583xxxx
there is also a IMEISV = 01
fenjen or enyone: were can i d/l ODIN?
OK i found by the firmware version on my GT-9100 that is for Trindad and tobago,
So my questions is wich frimware will work in the USA wiht ATT or T-mobile, Anyone using this phone ins the uS wiht no issues please tel me what firmware version your phone has.
My I9100 has: fIRMmware: PDA:LPE/PHONE:LPE/CSC:LPE (TTT)

I have baseband xxki4.
I should note to you (again) that regardless of what baseband you flash to the phone, and if you do end up getting signal, you won't get better than Edge speeds on T-mobile USA's network.
As for what firmware works on which network: it doesn't matter. All of them will work, but some basebands/modems will work BETTER than others, but they should all get at least SOME signal.
Also, there's one more possibility. The phone's IMEI may actually be blacklisted. Check with your carrier on that.

Problem to connect to 3G

hi everybody,
i have a UK T-Mobile Motorola Atrix that i received as a gift (MB860; 45.31.2.MB860.T-Mobile.en.GB; android 2.3.4). I live in Morocco where there is no T-mobile. I try to set the phone up to get 3G connection but it never works. it keeps trying to synchronize and changing the signal from normal to 3G to H and so on.
i tried my simcard in other phones and it works and I tried other simcards with 3G in my phone but still the same problem. i called my network technical service and they told me to upgrade the OS. i did it since there was an update available in the t-mobile web to the version mentioned earlier yet the problem persists.
when i see other phones with android there is a option to activate the 3g that i don't have in mine, i think because it's a t-mobile version.
can anyone here give me a hand with this?
thanks in advance.
