Hey, I`ve aquired the 2x 2 days ago and I think it`s something else, I`ve had plenty of PDA phones and smartphones, but the dual core experience it`s highly noticed.
I`m on Modaco Custom ROM, build no GRJ22, kernel 2.6.32.9, baseband vrs 1035.21_20110622, 2.3.4 and apart from random reboots, my Wifi doesn`t seems to connect if I don`t have data enabled. I say "it doesn`t seems", cause apparently it connects, browser is working, market doesn`t, gmail app doesn`t, weather doesn`t and any other game that requires internet connection doesn`t.
So in order to connect to wifi I have to enable data, then the wifi. Viceversa it doesn`t work or from some reason my wifi connection isn`t in range.
I only wanted to know if I`m the only one with this problem and how can be fixed.
Thx, cheers!
I have exactly the same problem. Someone released a brand new baseband a few days ago which I might have a go with. I didn't have the same problem on other ROMs.
Hi all,
does anyone know if exists an adapter to make O2X dual SIM. It would be GREAT because i have a personal mobile (O2X) and a mobile for my work and i would like to use the two SIM card in the same mobile.
Thanks by advance for your answers
The dual sim converters at ebay will work, since it does for my spica.
do you still have the link to the object please?
nobody ? please some answers
Did you try search for it at ebay?
Sent from my Optimus 2X using xda premium
yes but it gives me nothing
Never tried but is it that ?

None of the adapters will work with any 3g networks so if your network only does 3g and up forget about it.
There are lots here. 3G is working too. But only 1 sim is active.

Hi.
I´m from Germany and I had the same problem (two SIM, one privat and one for work). I bought a digital dual-SIM-adapter from g-telware (just search for it on google). This one is working pretty well. The SIM from my employment/work is a twin-bill, so I´m able to use and switch 3 Numbers (two on twin-bill-card and one on privat) via STK-App.
Unfortunately it only works with the Stock-ROM or a MoDaCo-based Rom. On CM7-based ROMs I have the problem, that switching between the SIM-Cards ends in an error massage saying like "We are sorry! The application com.phone.android isn´t working any more. Please try again later." (translated from German, I think the English massage should sound different).
Anyway, I don´t really think, that this is a problem of the adapter then a problem of the phone-apk used in CM7. Noone was able to tell me, how to solve that problem or why it happens, so I´m back to Stock-ROM.
Maybe someone here (for example some expert ) could have an solvation to that problem?
Big thanks for this good answer. I found g-telware website. But there are many SIM Card. Do you remember which one you buy?
I search a "no cut" adapter. If possible that is compatible with UMTS/HSPDA.
For your problem, maybe you can try to take phone.apk from Stock Rom and replace it in CM7. Or better, you can wait gingerbread update, i saw on another thread that it is scheduled in 15 days.
Thanks by advance

I´ve chosen the GDSA3G (search for "Art.Nr."). I tryed the GDS16th-A before, because I baught a Samsung Wave before. That one doesn´t work correctly in P990.
The phone.apk is not replaceable in a common way. I tried that with root explorer app, the phone.apk crashed.
So I will have to wait for the Update, but I doubt, that it´ll be released in 15 days. On the other hand, I´m of the opinion, that there has to be an explainable (and much more changeable) reason for that error in CM7. The only thing might be, that such a constellation like a dual-SIM-adapter is very rare, so that no one has ever thought about it (unfortunately).
Ok, i watched GDSA3G on the website. Can you confirm that you have to cut the sim cards ?

Solution for phone.apk crash?
Just want to mention, that I did a call forwarding from the "work" SIM-card to my private SIM. So people can call me at any time. In that case you should ask your employer, if there will be any costs doing this (in my case it doesn´t matter, because both SIMs are Telekom).
I´m still dissatisfied with the crashing of the phone.apk. Maybe one of the moderators could make this problem official?

Maybe this is one point on the list of not working features of CM7. Unfortunately I´m not allowed to post there at the moment.
Dual SIM on CM or MIUI build ROM
Hey Guy`s!
Already investigated a little in the above mentioned and apparently there`s no big shot at this issue within CM or MIUI Community! I know there`s one guy got it running with his own efforts on CM, don`t know about MIUI. I`m using MAGICCARD 3G, it`s a china made digital cut adapter which works flawlessley on all froyo and gingerbread builds with STK.apk. No probs here with battery issues or disconnects or whatsoever, just fine. Heard that it should work with it`s built-in 007 mode (switching by dialing 001/002) in CM builds, never tested it myself though. Probably I´ll give it a try the next days!
Regards BG1
Also got it running flawlessly here. Dual sim 28th gen Plus cut from www.magic-sim.com
I recently got the lg optimus x2. It is running on 2.3.4.
Initially, the wifi connected but 3g was not recognised even though data roaming and access was enabled. However, now i cannot even connect to wifi. It keeps saying 'obtaining ip add' and then fails.
Going through various google searches I have messed around with the settings, set apn to default. Done factory reset. Disconnected, reconnected, changed sim cards, tried 2g, messed around with vpn, selected all network mode's but nothing seems to work. I have contemplated rooting the phone but doubt this will do anything?
This is extremely frustrating considering the "amazing" reviews the phone has one expects a simple tool such as wireless connection to work.
Would be grateful if anybody had any other ways to possibly resolve the issue?????
Thanks

There are two things you could do ...
1. Return the LG 2X - if that's still possible
2. Switch to a Custom ROM
Installing the first official LG update to my phone was a major setback for me as a lot of things stopped working, that worked before. But switching to a Custom ROM made me a happy man.
Have you considered trying out e.g. DjangoManouche (2.3.x) it is based on the stock ROM but has massive improvements built in.
http://forum.xda-developers.com/showthread.php?t=1410662
If you feel like you want the ICS experience there is NovaHD (based on CM9)
http://forum.xda-developers.com/showthread.php?t=1508492
The only glitch with CM9 is, that there are currently no drivers for the Tegra2 chipset released which results in lack of FullHD video recording, beside that the ROM works like a charm.
I am running NovaHD on my 2x now and not willing to go back to Gingerbread ;-)
If there is anything I can help you with, just let me know!
Cheers!

I cant download clockworld mode...so i tried to do it through the computer...and now the phone wont switch on
Hi,
that doesn't sound too good - did you follow any instructions installing clockworkmod?
I installed it using RomManager on the phone itself, worked like a charm.
Did you root your phone already?
I couldn't install it directly as i had no 3g/wifi (initial issue)...after i transferred the Nova Hd file into the SD, installed clockworld through PC and attempted a restart it wouldnt switch back on
Have you tried removing the battery and inserting it again? - Did you turn on the phone while pressing volume down (until the first LG logo disappears)?
This should then boot into clockwork recovery if you installed it correctly before.

done both, nothing works- phone is dead as a brick
This might be a dumb question, but has the battery still power? Have you tried with the power cord attached?
Is there nothing on the screen, no lights blinking? Brick dead?
Does this sound similar?

hey guys im new on this wp8 forum (old android user) i bought an ativ S from a dude i met once... i knew this had a problem with the camera, i just realized that the back camera is the only one with the problem, ive been reading posts and i tried everything to make it work, but i allways got the same, it doesnt start correctly, i press the camera button or use the camera icon, but its allways the same, the 1st start its like it close so quickly at the 2nd try it keep the screen black, i only see the icons, and an arrow to swipe and see the pics i toke (with the front camera and a 3rd party app) but it close in around 10 seconds... idk what to do... i tought maybe was something about and update (a past one) but few days ago i got an update (not grd2, a minor one) but nothing... i still have the problem... what do you guys think... its a hardware problem or maybe software?... ireally love this cellphone and i dont wanna stop using it
If third-party apps can use the main (rear) camera, then it's not a hardware problem; you could try hard-resetting the phone and seeing if that helps.
If even third-party apps can't use the rear camera, it's either a hardware or firmware problem. Since this is the first I've heard of you particular issue, and since an update didn't fix it, that suggests a hardware problem (it *could* be firmware if you have some weird non-stock firmware on there; what version info do you have in settings->about->more info?). If it's a hardware problem, replacing the phone (or just living with the meh but usable front-facing camera, I guess) is your only real option.

thank you for your answer, =)
uhmmm, as you say i only can use the back camera with an 3rd party app, because when i try to open the pre installed camera app it close...and the camera icons appera in a gray color... except the arrow to see the taken pics, that appear in white...
i discovered some other ppl who had the same problem, :/
oh oh ok. my telephone info is...
Os version: 8.0.10327.77
firmware:2212.13.6.1
hadware: 15.3.1.0
trans soft: 2212.13.6.1
trans hardw: 0.0.0.0
(i actually dont know how to translate this from spanish): 13.04.19.21
SOC chip version: 1.5.32
this is the info i got, before uodating it, the number were almost the same :/
mmmm i remeber when the update was almost ending it was like 1/5 complete... then 2/5 complete... and after that the phone started...what i mean is that there was no 3/5 4/5 or 5/5 steps...
man so you are telling me i wouldnt be abble to replace just the camera, if is a hardware problem??? oh jesus =( i really love this cellphone i dont wanna lose it =(
thank you for your answer my friend =)
First of all: you have GDR2 and the most current firmware that I know of for the SGH-T899M. The line you couldn't translate is "bootloader" (the code that starts, or "boot-straps", the operating system). Your version numbers are identical to mine.
My rear camera works fine, though. Since third-party apps also work, you either have bad firmware somehow (doubtful, especially after the update) or there's something wrong with the Camera app on the phone (more likely). Unfortunately, the only way I know of to fix the latter problem is to re-install the OS (which a hard reset will, or at least should, do).
Replacing just one component, like the camera, is very difficult on a compact device like a modern smartphone. It might be possible, but the cost might not be worth it. On the other hand, if the phone is still under warranty, you should be able to replace for free.

GDR2??? are you sure my friend?? ive reading and that update come with the Radio app, some camera features and other... but nothing :/ i just got some options in settings and that was all, i even cant download or instal Ativ beam (i dont find it on the store, and when i try to do a manual install it say that is not compatible) and i heard that app is only for the last update
my cellphone is canadian i think, because the company is ROGERS, and i live in peru, so i cant use the warranty or something
i will try to save some of my info, and i will do another hard reset
Do you think there would be a tool for a diagnosis?? i mean conecting my cellphone to a PC in DOWNLOAD MODE or something???
i swear i wont rest till i fix it :'(
again, thank you very much for your time.
P.D: let me show you what the camera looks like for a while
Yes, build 10327.77 is GDR2. Your phone is a SGH-T899M, same as mine; GDR2, along with an interim update ("Amber" maybe?) and a Samsung firmware update, was pushed out to all Canadian SGH-T899M handsets (including those operating in other countries, like yours and mine) a couple days ago.
ATIV Beam installs fine for me; it's probably a region lock and not a matter of device compatibility.
Samsung is reported to have cheapened out on the radio chips for the SGH-T899M, and not included the one needed for FM.
Data Sense (assuming your carrier offers it) is supposedly included, but due to <REDACTED>-up update process, you have to hard-reset to use it (how the *HELL* did that make it through testing? That's supposed to be exactly the sort of BS that those months-long and tens or hundreds of thousands of dollars of testing per-update are supposed to find! Bloody incompetents...)
There's an app called Diagnosis embedded in your phone's firmware; you can install and launch it by typing either ##634# or ##3424# (MFG or DIAG) into the phone's dialer. Check the relevant thread here about dialer codes and diagnosis apps for some examples of things you can do with it (among other things, test the cameras). However, if the camera is working in third-party apps, I doubt that test will find anything. As I said, that indicates a software problem. Hard reset is the only really likely fix for that, if you can't get Samsung to service it. Flashing a stock ROM would probably work too, but I don't know that we have either the ROM nor the flashing tool needed for doing that.

incompetents!!! hell yeah!!! !
my friend are you some kind of wizard or something??, while you were writting it, i was doing a hard reset, and now i have data sense... and oh thats why i cant have ativ beam (NFS in WP devices suxs ass hell, i cant send anything) and... Doesnt have a FM radio???!!! SAMSUNG are you serious?!?!?!?...
i did the ##364# and i got the diagnosis item, thats how i noticed that the front cam worked fine and the "megacam" (front one) doesnt work... (i used the *#0*# code) plus the camera LED doesnt work either
oh well , after the hard reset i just got all my data lost n_n; , but you know... the frontcamera still doesnt work... tell me truth im already FU*beeeep*d ,am i?
i really want to believe that this have a solution...at least a non invasive solution...
I actually have the same issue. Before installing the updates from MS and Samsung the camera worked perfectly. When I updated my phone and did the hard reset, the camera behaves like you say, either a black screen or back to home screen. I called Samsung and they say it is most likely that the update did not install correctly. Though they talk rubbish sometimes as they also told me to update through zune........that doesn't even support WP8..
So flashing a stock rom "might" fix the issue. :fingers-crossed:
I just bought a second-hand Xperia 1 ii XQ-AT51 and didn't noticed then that Wi-fi and Bluetooth are not working.
And also that the bootloader is unlocked.
Besides from those issue and that the charging seems to be regular charging, not fast, everything works fine (NFC, Mobile Data, camera, features).
I don't know what the previous owner did, he clearly did something because the bootloader was unlocked; and asking and reading from other post, seems that nobody had these issues when unlocking the bootloader or rooting this model.
I locked the bootloader and tried repairing the software with Xperia Companion. Same software 58.1.A.5.507 (as I see the latest) before and after repair
Guess what: nothing different, although repairing was successful.
Then I unlocked the bootloader, flashed twrp as recovery (probably not necessary in my case) and flashed the stock software with Flashtool, latest from xperifirm (the same version I had before).
But I got some messages that some 3 things didn't flashed (not saved them).
Still the same.
Under Settings -> About it says Unavailable at Wi-fi MAC address and Bluetooth address.
With code *#*#4636#*#* I can see that the Wi-fi MAC address is 02:00:00..... (see attached image).
With code *#*#7378423#*#* at Bluetooth says Enable Bluetooth, at WLAN says enable WLAN, but on another Xperia I can see that it says OK for Enable an then Searching (see attached image).
Do you guys have any idea what to try to solve this issue or what to test in order to find the cause?
Thanks!
hi man ,i have same this issue with my mark II (XQ-AT52) , do you find out the way to turn on wifi and BT ?
Unfortunately no. After an Android/Security update the phone started to restart in about 2 minutes at max. So after 10 seconds or 1 minute it restarted, but not suddenly (like if you disconnect the battery), it was restarting normally. Then I tried software repair, but the phone would be stuck or get out of the flashmode. Enters fastboot but it wasn't seen by PC with adb devices command.
So now I have another issue that most probably will leave my Xperia as a brick. Sadly, because I really liked it.
I have now a SH Galaxy Note 10, but I'm planning to buy another Xperia when this brokes.
I also had the exact same problem as you, so I gave up later, when Android 12 push out and i upgrade but didn't solve problem, so I was wondering whether to continue using it without wifi and bluetooth or send it to Sony for repair.

On mine I also noticed after I bought it that it was opened, so I didn't found if it was hw or sw related, but since you also had this problem probably it is a software issue, or at least not a hardware issue because someone opened it.
Especially if yours is in warranty, I think you should send it to Sony.
If i use a third-party rom like miui , WIFI and BT sometimes can be opened and used, but it will cause the system to crash, so I also think it is a software problem ，maybe related to the persist partition 。
hi guy，I sent my mobile phone to Sony for maintenance. After they tried to update the system again, they told me that I needed to replace the motherboard, which cost $400 , so I gave up and now use the unofficial rom
