[Q] [QUE] How to root LG G2x with original updated gingerbread

Hi I just updated my lg - g2x with gingerbread released by t-mobile, my phone which was rooted earlier is not rooted anymore and i have tried all available versions of super one click but none is working. please help i need to try other roms.

Wrong place to be posting this... And there already are tons of threads on this...
But all you have to do is re-flash Clockwork Recovery, and install any ROM you'd like... Preferably a tweaked 2.3.3 OTA ROM.

Links
would you please post a link to that and rooted ota 2.3.3 rom please
i tried to find but nothing seems to work for me

Heres 2 links, 1 based off windows the other off linux. Dont know what OS you use so pick your medicine.
windows
linux
after you flash cwm simply flash your ROM and your done.

Rooting help needed badly

hi,
phone details are
LG P920, Android 2.3.5
baseband L6260_MODEM_Sic_01.1042.00,
Kernel 2.6.35.7, build GRJ90,
SOFTWARE VERSION LGP920-V20c-APR-25-2012
I have tried rooting thru superoneclick 2.3.3 and tried Megatron_Root_Dan_Rosenberg
with superoneclick, stops at step#7 and with megatron, get the message ädb"is not a valid command.
can someone please help me with a step by step guide for rooting the v20c as i have tried umpteen times with the above rooting tools but failed miserably.
I am more of a noob than a seasoned campaigner, please be patient.

Megatron Root
Hi,
Megatron root definitely works.
It took me many goes before it actually worked...It kept saying something about files being "corrupt" (it was a while back so cannot remember exact details).
The phone would reboot a few times, and end up being the same and unrooted.
What worked for me was i did a factory reset, and then ran Megatron root again. It may have had something to do with the number of apps i had on the phone. It then finally worked.
Hope that helps.

Hi Paki0402 and vicdo1000
Successfully rooted, I had to rely heavily on google translate for the german lingo
thanks again.

help greatly appreciated !!! ppl like you make us noobs feel protected !

This is a bit late, but adb is android debugging bridge, and is required to transfer files to root locations without su privilages. Adb is part of the android sdk and in the package of platform tools. To use adb you have to install it and configure it, look on youtube, then from command prompt you can us it.

Hi Schubeir,
CM7 is always a winner in terms of a good stable ROM, but you will lose the goodies that make our phone unique (3D as well as HDMI). Very fast and smooth, and because the ROM includes Theme Chooser, there's a huge selection of themes to choose from that will change your entire Android interface.
I'm currently using Promethius v1.3. Fantastic ROM...fast/smooth and keeps most of the stock LG apps. Feels like stock software, only much much faster and everything works! however, this version i dont think will work with your current baseband. you wont get and service if you flashed it.
Ultimately, there are many good ROMs to find in the Development section, so just have fun trying them out. whats good for me might not be good for you.
by the way, do you have ghost calls on V20C?

Hi,
Did not wait long enough on V20C to know if there were ghost call issues!! the UI was behaving like stop n go n stop n go, lagging every now n then, hence wanted to root and change over to custom rom.
I need to have the 3D and HDMI, purchased this model only for this. I am at present using the DNA_GB 3.3.3 based on the new V21E rom. when i flashed the ThiaiZ O3D V2.7.1 GB.------ NO NETWORK!!!!!
Was it due to the 21D baseband in the ROM? do I then need to flash the 21e Baseband?
which do i flash first, the base band or the ROM?
Cant believe I am trying all this at the young age of 52!!!
Thanks lots for all your help.

OK Schubeir,
I had the exact same problem so no problems. Yes the baseband is what is causing the lack of network.
I know there is any easier way to flash baseband, but i found it quite easy flashing my phone back to a stock v21e kdz, and then flashing a custom ROM built using the v21e as a base. The reason for this is V21E is proven not to have ghost calls, so thats the biggest benefit. it also has much better battery life. And finally, you can flash Promethius which has all the stock goodies (3D, HDMI).
Follow this link and go to point 3 - LG Flash tool.
http://forum.xda-developers.com/showthread.php?t=1491870
you must follow it step by step word for word or it wont work. Of course you will need to download the V21E kdz file...jut do a search and you should find it.
After flashing back to stock V21E, root again with Megatron, then flash ROM as you normally would. then flash GAPPS (google Apps) right away also.
Bit long winded, but its a one of and its well worth it getting your phone setup right. With Promethius, the phone runs awesome!

[Q] Lg Su760 Phone Help needed about Kernel and Rom!

Hello Every body, I am new on this forum forgive me if I break any rule by creating this thread but I really need your help. So getting to the Point I have just bought Lg Optimus 3d SU-760.
I know I should not have bought this phone not a lot of support Etc. but I bought it real cheap so I think it's worth the trouble.
It is a Korean Device with a lot of Korean apps and dialer and keyboard. I don't need. Now let me tell you about it's installed software and every thing.
I just updated it with LG Official Update tool it's running
Android Version: 2.3.5
Baseband Version: L6260_MODEM_SIC_01.1042.00
Kernel Version: 2.6.35.7
Build Number: GRJ90
Software Version: LGSU760-V20f-Mar-22-2012
Now my biggest issue with this phone is it's battery timing. I have read all the threads I can find in this forum and have came up with this conclusion.
I should install this kernel by iBluemind BlueKernel v1.1.0+ here http://forum.xda-developers.com/showthread.php?t=1565432
And then this rom XBSA V20F SU760 here http://forum.xda-developers.com/showthread.php?t=1664768
I already have installed Clockwork Recovery Mod and it's running fine. This is my first android phone I have used iPhone and Nokia phones before this one so I need your advice and suggestions any thing.
I believe I have explained my Phone and Situation clearly now coming to the actual Question Do I have any other choice other Than Bluekernel and XBSA rom. Can I install any other rom than this like The Promethius, ThiaiZO3D, CyanogenMod 7.2 or any other or should I just go with XBSA. Because users report lag in XBSA rom in it's thread.
Thank you, God Bless you all.

I think you can run prometheus 20f rom and use kernel with no "+". Give it a try..worst that should happen is no signal...

Okay thank you very much for the reply sir @Bdadd34 I'll try but it looks like it's only for P920. Lg Su760 is a three button phone are you sure it won't create any trouble like brick my phone or any thing

One more thing I wanted to ask is can I use Bluekernel as kernel and Promethius Project V1.4 as rom or should I use the Stock.zip file without the plus with this rom?

Hello Anyone please I really need your help please

Last time i tried a p920 rom in su760 it had problems. If you use su760 xbsall rom set cpu min 300

Thanks xbsall...I thought there was just +kernel and non + kernel phones..didn't know Korean model was incompatible..sorry for bad advice..
Sent from my LG-P920 using xda premium

Thank you very much sir, I am using this Rom for past week now @xbsall thank you again
So there isn't any other rom available right

I did get Promethius to work after installing the rom I installed Bluekernel and every thing started working, buttons and internal sd go mounted in the phone too. Network, Wifi three buttons every thing worked
Only I could not use USB mass storage option, whenever I use USB Mass storage my PC asks me that the memory card is not installed and I need to format.
If I press ye it shows memory card has only 10 Mb space..
If this issue can be resolved Promethis and Thaiz both can be used easily

you can try all existing p920 rom to out su760 as i did with mine, just use bluekernel for su760,everything works, card mounted properly and gsm, wifi, BT also works the only bug that i noticed is the camera is inverted, i hope somebody can fixed that problem.

Which version are you exactly talking about. Yes they work except camera as you say but usb Cable Mass Storage Option it does not mount in PC. External card mounts but internal does not
So can you please tell me what version are you using, I have tried Promethius and Thaiz and many others
Cyanogen does not work at if I install Bluekernel it stops on boot screen. And if I keep original kernel Neither Internal SD mounts nor the Buttons are fixed back button serves as Search

Hello, Can any body please tell me where this widget is stored in LG O3d SU760
com.android.internal.widget.DigitalKoreanClock
I can't find it, Or any other way to disable Seoul Clock from my lock screen.
Thank you

[Q] FW on PACman Rom v20 BUT WITH NO SERVICE, HELP!

Hi,
I am new to the forum so please be kind, getting straight to the point.
I recently flashed my Optimus 3D P920 to PACman Rom and everything when fine, only problem I have come across is that the I get No Service and Google Search not working properly.
After my extensive reading and researching of possible problems and solutions, I have come to realise that my basedband was V10 and that it was a requirement to be on baseband v21 whilst it was on stock Gingerbread software.
Obviously I have already done the flash, so my question is, is there in anyway of fixing this problem? Either via some form of flash, or preferably flash back to the stock gingerbread software.
I really require this communities help.
If any more information is required please do ask.
Thank you guys in advance!

restore your CWM or TWRP backupp you shold have taken atleast one backup on GB att some point and when you are on Stock GB do an normal LG update whit the lg update tool and after that should you be on V21E if you are Swedish. you will be on a V21 Base any way
and if you don't have a GB backupp then do you need to Do an unbrick guide to Restore to GB 2.3.5
