Well I've had my g2x for about 2 weeks now and I can't for the life of me get the july baseband! I started out trying to update it following lgs instructions and got a soft brick.

Managed to get it back to life with the help of these forums. And have since tried every method on xda and anywhere else I can find. It always fails (I've downloaded every driver I can find, deleted everything and redownloaded multiple times), will get partially through and say my phones not connected. I've even tried about every ROM available in the hopes it would be included (coming from sgs4g where ROMs usually include everything).

Anymore ideas out there about how to update (my laptop is win 7, but I see several others have still had success) :confused:

Hi,

Just wondering what improvements you experienced, if any on the JULY 15 baseband and WIND. I have been with Wind for 1 year now and I just picked up two G2X's free on the windtab+
[T-Mobile LG G2x] SL:
Depends...I have 2 LG myself and I had one on the June 5 baseband (wind) and the July 15 baseband (TM)

Both worked well, battery life was almost the same The July 15 had a small edge. The GPS is smoother on the TM baseband......
[T-Mobile LG G2x] xblitzz:
is there a way to Backup my current Baseband? I want to try the TM July 15th Baseband ... but I want to make sure I can go back if it doesnt work as good ad the one I currently have (since im not on TM)
[T-Mobile LG G2x] XMarinE:
Will this work if I want to re-flash my base band? I have the latest but think it's buggy...I have the issue with my phone saying invalid sim card. Someone mentioned it could be a corrupt base band. in other words I want to overwrite the current one with the same base band(Jul 15). The weird thing is that I can plug an AT&T sim in and the phone works, or my Straight Talk sim and it works...just APN changes to connect the data. Only my T-Mobile sims give me the error.. It is a new activated sim from T-Mobile and has worked on and off. I can place it in the phone tomorrow and it might show T-Mobile carrier and work,but if I reboot the phone or leave it on all night, it's off and says invalid sim again???

Hiccup

I had a slight Hiccup ... Didn't bootup ... saw the TMo animation then it restarted blank screen .... then restarted again .... tried going into recovery (btw: it was stock, had CWM before; guessing that's normal) .... I think it did a factory reset there and then finally it started up
[T-Mobile LG G2x] Gryncc:
this dont do anything it go thru and still no signal a? On the battery a unknown baseband and no imei
[T-Mobile LG G2x] BlazinHitman:
can anyone confirm if this update to the baseband actually improves reception/call quality/data transfer speeds?
[T-Mobile LG G2x] ZeroT| Demented:
It does
[T-Mobile LG G2x] loganmc10:
For those of you who've had issues getting this to work, let me tell you what I did (no guarantee this will work for you).

Basically you want to get right back to "stock", so:

Follow this guide:

http://xdaforums.com/showthread.php?t=1048274

To get back to Froyo (2.2)

And use NVFlash:

http://xdaforums.com/showthread.php?t=1056847

To put the stock recovery back on

Then follow the instructions in this thread, this worked for me (I'm in WIND in Canada) and I now have the July 15 baseband (with CM7 running)
[T-Mobile LG G2x] gustav30:
Has anyone tried the getril app in the market that is supposed to update the baseband for the g2x?
[T-Mobile LG G2x] loganmc10:
No no, the GetRIL app updates the RIL, not the baseband, all it does it detect what baseband you have and flash the correct RIL for that baseband (I've used it, it's pretty simple).
[T-Mobile LG G2x] da0ne:
worked like a charm thanks just did the OTA after i returned to stock
[T-Mobile LG G2x] ZeroT| Demented:
And you didn't save the update.zip why
[T-Mobile LG G2x] da0ne:
dont know where it was downloaded to tell me where and i will try to find it
[T-Mobile LG G2x] :
Dude THANK YOU :D I tried this a while ago, did everything I could think of with no luck, one try following your method and it worked! You just made another WIND customer happy. Thanks
[T-Mobile LG G2x] BlazinHitman:
As a wind user with the updated baseband, have u noticed any improvements in reception, call quality, or data speed transfers? Don't wanna update if theres no noticeable benefits
[T-Mobile LG G2x] d12unk13astard:
Did any of you save the update.zip from the OTA? Should be on root of sdcard..
[T-Mobile LG G2x] :
I only updated last night, but I live in a basement apartment and I've noticed I had more signal bars than before, also my battery was almost dead when I was updating (less than 20%) but after the update it showed 99% so I'm guessing it needs calibrating, but my phone hasn't drained all the battery yet! it's been about 9 hours since I updated and regardless of whether the battery was really 99% full or less than 20% it still hasn't died even though I turned wifi and data on for a while! Data connected faster than usual also, I'm in wind zone that has a fairly slow data connection so not much changed there! Haven't tested the GPS but it's supposed to be much better, and haven't made any calls but I've never had issues with call quality before so I don't see why I should with an updated baseband.

Lastly, it only took me less than an hour to do the whole update and restore my backup, whereas I spent a whole day trying to update before!

Hope that helps
[T-Mobile LG G2x] BlazinHitman:
Alright thanks. Maybe ill give it a go. I was really debating if i should do it cause im reading a lot of peoples posts that they are having a difficult time trying to update the baseband plus the added risk of soft-bricking the phone. I wasnt sure if was worth the hassle, but seeing as you are noticing some improvements i guess its worth it in the end. :D
[T-Mobile LG G2x] :
Soft breaking is very overrated, it's not as scary as some people make it to be (all you have to do is flash android 2.3.3 via NVflash (there's a post about it somewhere on the forums).

Also, for any curious g2x owners who are looking into updating their baseband, I did it on windows 7 64-bit home premium (no run as administrator, or run in compatibility mode, etc.), it said lost connection with phone once, I unplugged then plugged back in and hit restart and it finished in about 5 mins after that.
[T-Mobile LG G2x] shane1diamond:
After much much debate and curiousity, i wanted to know if the baseband update had any noticable advantages. Especially in the GPS arena So, I went into the Tmobile store to play with one of their G2x phones with the updated baseband and was upset to find that the it did! lol. atleast in the GPS lock. it was so fast that the blue arrow and voice navigation started before the screen even finished loading. I immediately tried updating using the tutorial in this thread. with no success (links would not download drivers for me). so i googled LG android usb drivers, and the LG update tool. Downloaded both, ran the tool, followed the simple directions using my windows7 laptop and Voila! new baseband with Blazing fast GPS, which ive been trying to achieve from day 1 with this phone. Thanks to the amazing developers i was able to get some good, and sometimes very good GPS locks "Tsugi". though now it is where i can say its PERFECT. although im now unrooted, and bloat is back. My phone is now where i am completely satisfied that everything works, especially the elusive GPS lock that i worked so hard to achieve and use ALL the time. Just FYI if anyone is having the same thoughts that i had.

: during update, progress bar seemed to hang in some spots @ 4% and 50%, but it did finally complete, taking about 20 minutes total. after update was complete phone seemed to hang a while before rebooting into a bootloop (lg and tmobile G2x screen). fixed by holding volume down and power. Phone rebooted normal, and phone is working 100%
[T-Mobile LG G2x] gustav30:
Ok. Going to do this tonight on wife's phone. Thanks for the tips above! Just to confirm, I lose root after this method?
[T-Mobile LG G2x] C0dy:
Yes, but you can Nvflash your recovery again, and then flash a rooted ROM.
[T-Mobile LG G2x] shane1diamond:
same nv flash method posted by tga gunman?
[T-Mobile LG G2x] C0dy:
Yep.
[T-Mobile LG G2x] gustav30:
Wow. Worked like a charm. Followed the OP instructions. I was gearing up for drama....but none.

Thanks
[T-Mobile LG G2x] shane1diamond:
Thank you.

Bricked?

So I decided to try the new radio and reverted my phone back to stock condition. The update program was going fine until after it uncompressed the files then it force closed in windows and now my phone is stuck at the s/w upgrade screen. Is it completely bricked?
[T-Mobile LG G2x] shane1diamond:
Does your phone turn on? if it does than its not bricked. did you nandroid your current rom? if so try booting into CWM (volume down+power) and run your restored backup.
[T-Mobile LG G2x] d12unk13astard:
If you have CWM on your G2x it's not bricked( however if your still getting stuck on the s/w screen after flashing a new rom/restoring a backup then yes your semi bricked)

Check out the Rom for Recovery thread in Dev section, it will low level flash you back to OTA GB rom.
[T-Mobile LG G2x] kabluey:
Awesome!

Thanks for the advice, I had tried to restore my previous rom with no luck. The Rom for Recovery worked like a charm and I am now at 100% stock thanks for the help. Is radio update worth the trouble?
[T-Mobile LG G2x] 95Z28:
I hear the radio update is worth it, but I've softbricked my phone like 10 times trying to get it. So until there's another method I give up. Or maybe I'll make a friend with an old ass windows xp laptop and try a few more times lol
[T-Mobile LG G2x] kabluey:
after I did the rom from recovery method and it was 100% stock I ran the lg update off lg's website. Then did the one click recovery flash and restored my previous rom. Now I'm re-rooted with the july baseband version:D
[T-Mobile LG G2x] d12unk13astard:
You mean you downloaded the b2capp.exe program and ran it on your pc or does LG have an updater online on its website?
[T-Mobile LG G2x] 95Z28:
Nope no online updater on LG website unless they added it in the past 36 hours. I hate that damn b2capp program, it was a pain trying to find and delete it off my laptop.
[T-Mobile LG G2x] fabolous02000:
What does updating the baseband actually do for your phone?
[T-Mobile LG G2x] Gryncc:
Can u fix mine please I'll pay name the price
[T-Mobile LG G2x] radu242:
I just updated to the new baseband successfully, and restored back to Weapon 3 and CWM 5 on my first attempt on Windows 7 (x64). Neither the internal or external SD was erased. Am I just lucky?
[T-Mobile LG G2x] Core Memory:
Luckier than Gryncc
[T-Mobile LG G2x] dylyxcore:
After this tutorial can I flash a nandroid backup or will that reinstall the old baseband? Looking to do this tonight, hopefully it doesn't piss me off lol
[T-Mobile LG G2x] Edward2868:
i just did mine on a windows 7 ultimate edition and worked fine. it was done in like 5 minutes.

after it was all done i used nvflash to gain root access again and then went into recovery, wiped and alla that stuff and loaded my backup and thats it. PRESTO. back to normal wth a new baseband :)
[T-Mobile LG G2x] dylyxcore:
Did you just run it normally (no compatibility or admin mode?). Also wondering if you just used the LG tool without reverting back to stock or anything (using current custom ROM). I am currently running ICS MIUI so I am a bit skeptical.
[T-Mobile LG G2x] nmyron:
Just wanted to kick in my $0.02...

I just used this tool to update my baseband, from Windows 7 Enterprise x64, with CWM already installed on my device. Here is what I did, however, to ensure that it worked properly.

Go here and download/install both the USB Driver Package, and the LG Mobile support tool in Steps 1 & 3 (The LG MST is the B2C tool the KDZ flasher cries about...)

As I said, however, I had also previously installed CWM on my phone, so, I have the APX driver installed as well. Since this reboots into fastboot/NVFlash mode, it may require that as well. I dunno that, as I haven't tested without it installed. But, may also want to have followed the instructions from here as well for installing the NVidia APX driver, as fastboot NVFlash seems to require it (couldn't use NVFlash to install ClockworkMod Recovery without it, and since you're rebooting into fastboot NVFlash mode to install the update, it may also be required).

After that, it was business as usual. Started the KDZ Updater (no run as admin, nor compatibility mode on it, and i don't recall the B2C tool popping an elevation prompt when it launched after you click Upgrade Start), selected the KDZ file, clicked Read Phone Information, then Upgrade Start. Waited a bunch, phone rebooted into fastboot NVFlash mode, USB disconnect/reconnect sound happened a bunch, and IParam painfully took it's time to tick up to 100 (just over 7 minutes)... It then rebooted, I am back at my stock ROM (just got a replacement from Asurion this morning), and am about to flash Weapon 3 in a moment...

Baseband listed as M6600A_SCAUNTZ-2.0.9720T 1 [JUL 15 2011 10:00:00] MP:TRULGE_08.09.02R_MDM

I've used the B2C app to update to the stock GB when it became available, so, it does work in Win 7 (I run 7 x64 Ent on both of my office computers, and Win 7 Ultimate x64 on both of my home computers, and it worked fine in both locations previously). Being as the KDZ tool requires the B2C LG Update tool to be installed, I figured it would be ok, and it seems to have panned out... You just have to download and install both from the LG link above.

DISCLAIMER: I am not responsible for damage to you device... I've been at this for quite some time, so, I may be able to help out with soft bricks if needed. This process worked for me, but, may not work for others, I offer no warranties, nor any guarentee that following the above will help you. It's completely possible it was absolute luck, and may entirely brick your device... Use at your own risk!

EDIT: Seems that, after completing this, it has removed CWM. After completion I had to redo the CWM NVFlash process
[T-Mobile LG G2x] oOo B0XeR oOo:
WORKS w/ XP ONLY

Yep... took a while but this method worked for me. July Baseband affirmative, over.

I found that the instructions all over the forums varied and some small steps 'could' be missed depending on your version of everything really. I do keep seeing that this seems to work on XP ONLY... luckily I have XP on this machine and it did work for me.

Basically you need to NVflash the stock recovery & OS (unroots); then update OS using the LG PC/USB Tool; then run the KDZ files; then reflash NVflash Recovery; then NVflash CWM (re-roots); then CWM flash any ROM & GApps. Then the fun of restoring your apps/settings begins :)

[T-Mobile LG G2x] prot287:
I followed the instructions exactly, but I'm not able to update. The LG support tool says, I already have the latest version and won't let me update.

There is also no option to choose "different country".

When I press "upgrade start", the LG tool pops up and I have to click the "Options&Help" menu to get to the country and language settings. I don't see this tiny step in the instruction nor anyone else's instructions.

Can someone help? I flashed the stock T-Mobile GB on the phone to begin.

Thanks.
[T-Mobile LG G2x] oOo B0XeR oOo:
No country option in newer version... disregard that step. You need to wipe your GB ROM and start fresh. The gb 2.3 is what you need to upgrade to thru the lg tool....because bundled in the official LG one is the July baseband. You need to revert back to stock...meaning stock froyo 2.2 like when u got ur phone...not just any stock rom. Its the V10f.xxxx one. Its all over this site, ....look in the NVflash thread for a link. Once on froyo start this process over. Yahtzee!

few things, in case anyone's searching for the forums on this. the baseband update fixed my gps. before, i wasn't able to get a gps fix no matter how long i let it run.

i'll +1 the method below:

CWM backup

Wipe and flash the latest stock ( http://xdaforums.com/showthread.php?t=1048274 )

Reboot

Turn off

Use One-Click NVFlasher to restore stock recovery ( http://xdaforums.com/showthread.php?t=1056847 )

Reboot

Use the LG Updater tool to install the latest baseband (had to install drivers to get it to work, including the B2Com thing, since i'm on windows 7)

After update, use One-Click NVFlasher to restore CWM 5.x.x.x

[T-Mobile LG G2x] cellsafemode:
really what's the point? this radio and the old one are the same version. just different date, nobody has been able to prove anything of any significance is changed in this radio from the older one and GPS takes a really long time to lock no matter what radio or rom you have or use.
[T-Mobile LG G2x] rayman2k1:
i've got a wind g2x and this is just not happening for me.

tried it with every god damn combination possible:

EB, PB, V10f, V20e, V11h, V21e. All with both Stock recovery and CWM. if i click Read Phone Information, then Upgrade start, most times the LG tool reads the s/w version as 11h (which is standard on wind) and tells me that it's up to date. other times it reads it as 11h, lets me get to the stage of upgrading, then tells me that an unexpected error has occurred.

if i just click Launch software update on the KDZ tool, it gets to Model Dll Msg Not Found(2000, 0) or one step after and it just stays there for hours.

i've tried all of this in windows 7 professional x64 sp1 and can't get very far with just the kdz program (it crashes) and the consumer lg tool gives me the same results. the furthest i get (which are errors, mind you) is in windows xp x64 sp3.

i'm at my wit's end here. has anyone had these issues and been able to solve them?

thanks..

It seems some of us Wind people are not able to use the LG tool due to the already up to date message. Experiencing the same thing here. I gave up for now.

Maybe Wind can't use the July 15 baseband? If you bought it recently it should come with the highest baseband you can use, since I bought mine last october and it came stock with the July 15 baseband. On T-Mobile USA.
[T-Mobile LG G2x] prot287:
My Wind phone was purchased in Dec, 3 months ago. So, it's fairly new. It's got June 5th version though. I wanted to try the July 15 baseband because my older Optimus T has significantly better reception.

I followed the exact steps and LGs ****y updater stuck in the middle soft bricking my phone. had to use the nvflasher to restore to the stock rom, with the updated JUL 15 radio. ive been using this baseband for a month already, didnt notice any major change. maybe psychologically the gps feels a bit faster (still takes up to 3-4 minutes to get a lock). same battery life, same reception, mostly same everything. anyways, thanks for the guide and the baseband files. for sure it feels much better knowing that i have the "updated" baseband :)

BTW, is there any real need to update the RIL via getril app ?

Thanks!

Yes, I am on June 5th BB having issues.

My GPS is slow to lock on but it does lock after a while. I haven't tested too many times though.
