T-Mobile USA 2G / 3G / 3.5G / HSPA+ / "4G"

Anybody on T-Mobile US with the p990 / su660?

I'd like to hear if you are also having problems I have had...I can only have stable signal when choosing "2G only". Otherwise, signal keeps dropping and end up with "No Service".

I realize that to have access to HSPA+, the frequency needed are 1700 / 2100. My su660 has 2100 but not 1700. Does this mean I cannot access the HSPA+ speed?

If not, then what can I do to get at least the 3G speed? that is without service drops. I tried manually entering the APN with the "T-Mobile G2" setting (the one with proxy server address), but still no luck.

Thanks in advance. I'd appreciate any advice you may have!

EDIT: Found solution here on how to resolve network service drops for my CM9. Huge thanks to TIITHE!

EDIT#2: Sadly, NO, I cannot use 3G/3.5G (marketed as "4G" by T-mobile USA) with my SU660 O2x. Apparently a phone needs to support the 1700 MHz frequency in order to have 3G speeds on the TMO US. :(

I'm not too familiar with temasek's builds. Are they based on the same code as the CM7.2 RC1? If so, then you don't have to do a full wipe.

In general, full wipe is recommended and needed to be "safe" as you said. But if you're flashing same kinds of roms, it's not necessary. For example, if you regularly flash the cm nightlies, it's not necessary. I also regularly flash Owain's CM9 kangs without full wipe in between.

There were times though I messed up something badly between flashes and did a full wipe.

But as long as you have a good nandroid backup, you should be safe. Feel free to experiment! (I've learned a lot this way)

PIN prompt problem

I to you all guys!

I'm recent in this forum, but i follow you, for a long time.

I need your help, in a small issue:

After several Rom's installation, i went back to stock rom. But during an factory actualization, something went wrong. After that, no matter what rom I'm using, the PIN prompt has some difficult to appear. Robot's one after another, until it show.

I'm talking about 8 or 9 reboots. why is that? Software or hardware problems!?

I appreciate your help on this, and congratulations to you all for the nice job you've been made.

Eagleblood AIOS 4.0.4

So, I flashed my LG Optimus X2 with the Eagleblood AIOS 4.0.4. I tried writing in their post but since I havn't posted 10 posts yet, I couldn't.

Anyways, the rom feels extremly responsive, but the battery is draining faster than before, and no video-recording. Other than that, It's the best rom I've tried yet.

APX

Hey guys I have been triying to revive my bricked 2x trough the guide here in this forum but I keep getting stucked in the part where the computer should recognise the APX device. its just doesnt show anything and also. I didnt know how to install the .inf in the APX driver folder so I used one guide in other page and I think I did but maybe not the right way?. In the devices it appears "nvidia usb boot recovery..." so PLEASE HELP!!

Uhm. Im not really sure, how do I know if it does?

When I turn it on it boots normally but then it stays in a LG logo screen. I tryed the (power + vol down) thing and it reboots and shows the little box with the android toy but then goes back to the LG logo /:

I've read alot in the forum and may users say that if its booting and turning on I can revive the phone so I hope we can save it

Best Custom ROM

Hi guys,

I'd like to know, which Custom ROM is the best one for the LG Optimus 2x. And also, which launcher works better for our mobile phone? (I like performance driven launchers.)

I'm using the last CM7.1 nightly build (cm-7-20120610-NIGHTLY-p990)

I'm very happy with my MIUI. It's fast, clear, and has some really nice features and tools.
[LG Optimus 2x] FelipeBHZ:
Worth a try

I'll try this one.

Sometimes CMs are not so cool. Too many crashes on launchers and some apps. ("not responding erros")

Ps.: To flash it to my LGO2X is the same as CM? Just copy .zip to my SDCard, boot into recovery do a full wipe of cache, dalvik and user data (just in case), and update it from .zip?
[LG Optimus 2x] IppeZiepe:
Yep. That's about it. Maybe use an app like GetRIL to find a RIL that fits, but usually it works straight away.

Thanks a LOT for the help guys
[LG Optimus 2x] Rusty!:
You should really be in the P999/G2X forum, they have recoveries over there too (I built some :D)

You don't really get APX drivers to 'work' they're just there. Remove battery, hold both vol buttons and plug the phone in to USB. Nothing will happen on the phone, but Windows will pick up the device and you just have to point it in the direction of the APX drivers.
[LG Optimus 2x] Nourer:
Got it! I will keep trying and if I keep having troubles I will ask on the G2x forum. Thanks a lot for help

MIUI is Nice!

Hi IppeZiepe,

Just tested MIUI for the last two days. It's REALLY cool. I have an iPhone too, só MIUI is like iOS in lots of parts, but with the useful tools and widgets of Android.

Seems they have created a ROM with the "best of two worlds". :)

I'll keep MIUI for a while, and maybe soon I'll test another CM7 called "Chuck Norris" with a lots of new features and a different Kernel, which overclocks 20% of O2X's processor. 1.2ghz x 2 should be good.

:)

If you have any considerations, I appreciate.

[LG Optimus 2x] Imperticus:
There are no best rom per se, only what preferences you have.

Stock based ROMs improve on original LG rom. CM7 based ROMs provide AOSP experience with many added features, and are considered faster than stock ROMs. CM9 are ICS based ROMs, however they are buggy. Look through the O2X development section for various ROMs.

Hello everyone

This is my first post although I've joined this forum 3 months ago. I was wondering if yours O2X got this problem.

MIUI + ETaNa Kernel

Hi guys,

I'm a newbie to the world of ROMs and Kernels. I'd like to know, if I can flash a Gingerbread version of MIUI on my O2X and Flash any ETaNa Kernel to it, eg.: ETaNA 3.0.

I'm now using CM7 + a version of ETaNa, but i'm willing to change it to MIUI.

Ps.: The main thing for me on ETaNa Kernel is the overclock. 1.2ghz is great!
[LG Optimus 2x] aragorn7:
Front cover?? I don't have anything in front my glass...

If you mean the back cover that covers the battery, no, mine isn't higher than the bezel. Rather, it fits snugly.

So I'm not sure if that "helps" you but sounds like you have a defect...
[LG Optimus 2x] vutung2311:
Thanks for your reply.

Oh, I'm sorry for my mistake. What I called front cover is actually the digitizer of the touch screen. It's a little bit higher than the frame around it. I searched about O2X in YouTube and find out that those other O2Xs did not have this issue. It seem to be that the adhesive between the digitizer and the frame is not sticky enough to keep it tight. :(

Temperature P990 LG O2X

Hi guys,

I'd like to know what is a good temperature for the LG O2X. I just flashed a Kernel with overclock option (ETaNa_OC_v.3.0.y) and got SetCPU to set it on 1216Mhz. The temperature showed on SetCPU widget is 30.8ºC (87.4ºF). Is it ok? What temperature would be too high to damage my phone?

Many thanks.

[LG Optimus 2x] bliizzz:
U mean while overclocking or normally?

normally my phone was left in the car....during summer.....it reached 56°c
[LG Optimus 2x] FelipeBHZ:
I mean with CPU set to 1216Mhz instead of stock 1000Mhz. So I can keep an eye on it, to avoid high temperatures. Got it?

I try not to go over 40C. mine reboots when it's too hot
[LG Optimus 2x] aragorn7:
Did you do a custom repair on yours? That's too bad it isn't a snug fit.
[LG Optimus 2x] FelipeBHZ:
Thanks Aragorn,

I'll keep an eye on it, and check if it will reboot on temperatures higher than 40ºC.

I got almost 3900 in Quadrant Standard with 1200Mhz set, is that right. With 20% of overclock O2X can "beat" Galaxy SII ?

;)
[LG Optimus 2x] aragorn7:
Check out my Quadrant score from a while ago with scores close to ~5000:

http://xdaforums.com/showthread.php?p=26355462#post26355462

The above linked Quadrant was done with oc to 1.4GHz.

But don't put too much faith in these numbers. The scores can vary considerably with the same setup. If anything, it just reassures us that O2X has great hardware and potential, as long as it can be harnessed properly. ;)
[LG Optimus 2x] FelipeBHZ:
Hey IppeZiepe,

which Kernel do you use on your LG O2X with MIUI?

---------- Post added at 07:42 AM ---------- Previous post was at 07:36 AM ----------

Hey Aragorn,

today I woke and and my LG had crashed during night.

I had to remove the battery to reboot it.

I think this ETaNa Kernel I was using is not so good.

Is there any other Kernel with overclock (low OC, like 1216GHZ would be alright)?

I heard about Temasek's or something. Do you know where can I get an update version of this one?

Thanks
[LG Optimus 2x] aragorn7:
That depends on what rom you are using. I only have experience with kernels made for CM9 roms, and I believe the following can OC (listed in no particular order):

If you browse the O2x android development forum, you'll also find a number of kernels for CM7 and stock roms that you can use (if that's what you have).

Since each phone behaves slightly different, you'll have to find the best configuration for yourself. Have fun with it and good luck!

While flashing rom i have only 5% battery so im going to cwm mode and plug in the charger at. The same time ,flash the rom and reboot whether its posible that the phone wil get charged in cwm mode?
[LG Optimus 2x] aragorn7:
Yes. It will get charged in recovery mode.

I'd recommend having a full charge though before flashing. In my experience, the battery calibration got messed up in the past when flashing a new rom with a non-fully charged phone. Maybe it was just my bad luck, but just a suggestion.

I flashed ICS NovaHD on my LG P990 yesterday, and it's pretty nice. Everything is working fine, except video in HD or video camera. Ok, I'm fine with that.

But, one thing is annoying me. I use Swype BETA keyboard and Plume for Twitter. Many times Plume just closes. And other apps too. Suddenly it closes, no error messages like "not responding", and I have to open it again.

My question is: Could this be a Kernel problem or not? If not, what problem is this? If yes, what kernel is better? I'm using the kernel 3.0, which is the original from ICS NovaHD.

Thank you guys.
[LG Optimus 2x] tonyp:
I don't think it's a kernel problem, probably an error with because CM9 isn't fully working on the 2x.

Does it happen with Swype only or with other keyboards as well? Are you using the newest Swype ICS version?

Hi all!

I flashed from blazing dragon to CM7 temasek`s build 126 few days a go and keep getting strange battery behavior now. Phone seems to be really stable and fast and i have got no random reboots or freezes while using it. But when charging overnight the phone shut down and few times the battery percentage is 1-5% when i start the phone again. It does start straight from the power button (no need to pull the battery off). This only happens with extended periods odcharging, not when charging to 100% and then pulling the charging cable off.

Also the battery drain is huge, i`m only capable of about 14-20 hours uptime with moderate usage. The battery usage for last charge is:

Cell standby 20%

Phone idle 19%

Android system 19%

Dialer 18%

Viber 17%

Voice calls 6%

Wi-Fi 3%

I did do a full wipe and battery calibration when i flashed the new rom and i`m using the 725 BB with matching V10d Europe RIL. I also installed the 140612-1427-temasek non-OC kernel.

I`m new to these forums and dont have rights to post to development threads. Could someone help me out? Thanks!

Changed Kernel

Tony, I've been using Horse Power Kernel for the last two days, and seems the problem has been solved. Of course ICS ROMs are not the best choice for P990 yet, but with this Kernel and OC of 20% (1.2GHz), seems to be better and much less crashes, I would say none 'til now.

Battery is quite alright, around 40% down in 3 hours of twitter (Plume) and Browser usage.

If I have any considerations, I'll post here or on the Kernel's original post.

[LG Optimus 2x] andrazz90:
I have a year old O2x, which i restored to factory settings about 5-6 months ago. Now the phone is not rooted and am using the V20g rom 2.3.4

The reason why i restored factory settings is because it was lagging, now it started doing it again, the ui lags, even with custom launchers, games like angry birds lag, browsing the internet lags. and by lagging i mean at times worse than my old nokia 5800 and any htc wildfire(1st one) . could the phone be faulty? would it be enough reason to return the phone under guarantee, it also has screen bleeding from 3 corners. *edit* the phone sometimes randomly dismounts my external sd card (happened with 2 cards and does not mount untill i remove the card and put it back in) and does not find wifi signals.

So, i've bought a LG 2x SU660 and now i want to upgrade it with NOVA HD mod rom, but i can not find a working kernel for my SU660. Any help?
[LG Optimus 2x] aragorn7:
Sudia,

Check out the kernel by wkpark:

http://code.google.com/p/openstar2x...=boot-cm9-for-su660-3.0.8-120322.zip&can=2&q=
[LG Optimus 2x] sudia:
Thank you a lot! It worked like a charm:laugh:. Btw, i saw your signature and realized that you've used harsh kernel on your su660, is it even possible? Is it only for p990? Just my curiosity, then.
[LG Optimus 2x] aragorn7:
Harsh kernel is designed for P990, but the p990 is similar enough with su660 to be somewhat compatible. I say somewhat because, although I didn't get bootloop using Harsh kernel with my su660, I do have following issues to deal with:

1.Cannot use the three buttons at bottom of phone. As you may know, p990 has four and this difference makes my su660 unusable.

2. Gyro sensors are flipped. If I turn the screen 90 degrees, it actually rotates the screen 270 degrees and vice versa. In a game called Temple Run, the character goes left when I turn the phone right.

The above issues hold true for all kernels developed for the p990 o2x.

How do i still use harsh kernel?

Thankfully, recent rom builds by owain94 includes "edge navigation" which allows me to assign the menu, home, back keys to the left, bottom, and right edges of the screen. (I left the top edge unassigned to keep using the notification drawer). I'm very grateful to Owain for this feature, which now frees me up to test different & latest kernels that are in development (at the moment, su660-specific kernels are not being developed as actively as those for p990, at least here at xda)

For the second issue, I just keep my rotation disabled. I don't play games and it's fine for my use.

Hope that helps.
[LG Optimus 2x] sudia:
Very clear and simple answer, thank man. Look like i should try this feature with Domination :laugh:

Could you not just enable the ICS nav bar?
[LG Optimus 2x] aragorn7:

[LG Optimus 2x] tonyp:
Yes, that's the default behaviour of ICS.

You should be able to enable the navbar on my new PARANOIDANDROID port without the need to use a density of 128 or lower.

But I don't want to shamelessly promote myself, the main reason I post is:

Have you asked harsh if he could release a kernel for the SU660?

I know he's doing one for the G2x as well, there it wasn't hard to build it.

Maybe he can just pick some commits from wkpark and it works for you (and the su660) as well.

If you haven't asked him yet it's worth a try :)
[LG Optimus 2x] aragorn7:
Congrats on your new rom tonyp! You've helped me numerous times before and I am excited to try out your rom :)

[LG Optimus 2x] aldyu:
1-2. Yes, SuperOneClick from shortfuse is the easiest way to root though there is a manual way of doing it, done it several times with my O2x plus you can unroot with it also.

3. The CM7.2 Official is great but you may want to try also the build from Temasek, it's also great specially if flashed with his kernel which has ramhack and can be OC'd. If you want to try out cm9, you have 3 choices, from owain94, nova hd, and xxmrhyde, i prefer the build from xxmrhyde since it's the closest to source and clean with nova hd kernel or harsh kernel to support usb mass storage, of course no hw yet.

4. For me, I downloaded a copy of the stock rom(.bin and .cp files) so that whatever happens, i can smartflash rightaway and it's good as new. Or you can back up you current rom, you choose.

5. Just be up to date and as what xtrustkillx said, reboot the phone once in a while.
