Rahul… It worked for me, It didn’t give any error. I did not remove the batery or enter into s/w upgrate mode. I’m from Mexico and I just followed the steps the way it says
Hello I am from Mexico, is this FIRMWARE, unblocked to use it in TELCEL, MEXICO?
Manuel: Tuviste que desbloquearlo o simplemente lo instalaste y LISTO!, saludos desde Mexico.
Words very well in hungary! cheers for the solution!
Actualice el equipo paso a paso y todo perfecto pero no pude arreglar el 3g ):
It is not necessary to ask anymore if this FIRMWARE works, I follow the instructions an it works.
THE ONLY THING IS THAT THE NETFLIX APP, DOES NOT WORK, I THINK THE REASON IS THE COUNTRY CONFIGURED AS GLOBAL, I THINK WE NEED TO CONFIGURE IT IN THE EXACT COUNTRY, BUT IN THE “UpTestEX_mod2_marwin.exe” app, there is no way to select MEXICO, but other than that is UP and running.
JUAN: A que te refieres con 3G, al INTERNET vía 3G o la selección del operador TELCEL en banda 3G?
Aleks: Solo lo instale y listo, no tube que desbloquear nada de nada (Tengo Telcel)xD Me funciono muy bien, intentalo y me cuentas como te fue a ti, va?
Manuel: Thank you it worked well on my LG Optimus 2x for TELCEL MÉXICO, I just couldn’t get working the NETFILX app, could be the misconfiguration of COUNTRY or lack of compatibility between GB 2.3.4 and 2.3.7, because I have it running on a Cyanogen 7.1 the yesterday nigthly.
Manuel: Gracias!, ya lo instalé me aventé al ruedo y listo… solo que no pude hacer funcionar la aplicación NETFLIX, eso me hace pensar dos cosas ó está mal configurado el PAIS o de plano esta versión de GINGERBREAD no es compatible a la 2.3.7 que tenía en la cyanogen…
Use Enabler.exe and turn to “ON” <– where to find this ?
Turn On UpTestEX_mod2_marwin.exe .select your KDZ file. Set emergency, <– also this
My Friend Shah, all you need it’s in:
+- Windows Enabler.exe (Enabler.exe)
Download all stuff follow the STEPS, see the images, AND enjoy!
tengo una duda….soy de mexico, mi optimus 2x, esta rooteado y le instale el clockmod, eso no debe signifcar ningun problema?…funciona todo bien…es decir la conexion a red 3g es estable? el gps funciona?la salida HDMI funciona?…estoy pensando si me espero o lo actualizo de una vez…
The update was great, but i can’t change the language (when i want to write an sms) to hungarian or english The language all the time Far-Eastern is left over
The problem was resolved
Please help me. I don’t understand with the last screenshot of the step 8 (pic3). Is that compulsory to change the country and language to Hungarian?? OR can choose others??
It works great:)
(From netherlands, EU open)
Can i pick another language besides “hungarian”?? please is urgent
Eso mismo, puedo seleccionar otro lenguaje en vez de “hungarian”?
Where do I download the
The “hungarian” language issue: you can pick any language you want. I think is only the language of install program.
The files problem: all the files are compressed on zip files ready to download above.
Do I need to switch off the phone, remove SIM Card, memory card or anything like that??? It says R&D Test Tool (Not responding)
When I click NORMAL WEB UPGRADE, it takes me to another window to Start the upgrade. Is the button I must press or is it the one on the main window?
could you re post the image in another link, can’t see it in indonesia. it says domain unregistered, block login !! Help pleaseeee
Works good, man. Thank you.
When you click the, normal web upgrade, click the, update start (or update now, I forgot) button. And on “Set emergency, 3gQCT”, emergency is on phone mode, top right. And 3gqct is on the top left with “select type”.
will this update work in India??
will it gives any type of error????
is there any internet connection required???
Hey I tried did and it worked, but I’ve got a problem. The clear button on the notification bar disappeared. Anyone else experienced the same thing?
problem with 3g cannot connect using 3g only wifi!
You need to configure 3G manually, but is really easy, for Mexico/Telcel do this: http://www.google.com/support/forum/p/android/thread?tid=5e750231d361e730&hl=en
“The program quit unexpectedly” Now that’s odd…
I might be an idiot when it comes to rom flashing, so can someone please explain how to get to the third screenshot, in step 8? As for the program quit unexpectedly, that happens after I press the start upgrade button on the main screen of the R&D test tool. If I do what the pics said, and press the same button inside the normal web upgrade test menu, it just jumps back to the main screen, and nothing happens. Any guesses?
Never mind, figured out the problem.
did evrything as shown in the pictures but still got strucked at 4% during the update :-(…It is asking me to restart the phone and connect back did that twice but still no use
I have the same problem Bryan had. If I change the keyborad language to english or hungarian, I only can use the language, what was installed with the update (some Far-Eastern Language).
same issue with me shaik…. some help anyone?
I was stuck at 4% but I noticed windows was installing drivers in the background. Then I did it a second time and everything went smoothly. It probably worked the second time because all the drivers were installed when it got stuck at 4% and it just needed a fresh start so that the drivers will work properly. Sorta when you install a new driver for something and you have to reboot your PC. Hope this helps.

Thanks! It worked ok. My lg is now much faster but my gps do not work properly any more.
Does any one have some idea what shod I do?
I am not able to run B2CAppSetup.exe – after download it runs, starts downloading some more and stucks at the very beginning. Is there a way how to directly download whole B2CAppSetup.exe?
You forgot to tell newbies like me one crucial thing! Do you download all the stuff to the phone and unpack or to the computer?????? I am reading this from my computer for example. I really don’t know what to do, don’t know if my phone can unzip, how to get the files to the phone, etc. On my Galaxy, it’s easy. Not so easy on an LG.
Well it’s been a week since I upgraded and my phone’s not had the Black screen shut off problem once. I would say it was a nervous time of it as it kept asking to have me remove battery and restart the phone but in the end it worked well. The only issue I’m having is with poweramp but that’s something I’m not that fussed about. Thank you so much I was just about to send it away to try for a replacement.
