Hi, looking for some help. I am currently using XBSA's ROM and I really like it. However, I am using the Blue kernel as it is the only one that gives me phone signal and wifi. I would like to use the Prometheus 1.5 kernel for better performance.
I flashed v21e fls and bin using smartflash tool but I've read that it may not have done a great job. The RIL does not match and actually the phone has no signal if I do match it to the baseband. I don't get ghost calls.
A problem I have is that I'm supposed to remove my battery and connect the USB cable but with no battery, my phone cannot run for more than a few seconds on my PCs USB power. Not sure how I managed to get SFT to recognise my phone last time - I kept messing about with it but left the battery in.
So in summary, what do I need to do to get my phone working with the Prometheus kernel and how can I get SFT or LG Flash Tool to recognise my phone?
Thanks

If you are using bluekernel some modules are changed thats why you probably have problems. You need to replace them with original if you change kernel.
About the phone getting recognised turn off phone remove battery, insert battery and just press vol up.

OK thanks, I'll give that a shot. I'll try reflashing 21e from a different source.

It was my understanding that the ONLY guaranteed way to get the v21e baseband to update properly is to install the official LG stock ROM for V21E and then switch to your ROM and kernel of choice after that.

You are probably right. That's what I'm going to try now but I can't get my phone recognised by LG Mobile Support Tool, so I have split the 21e KDZ into a fls and bin using jes0411's tool. I am going to try to use SFT to flash the bin but I can't get it to recognise my phone either :/
Time to page XBSA...

I'm sorted. Xbsall spent ages helping me out and got it all sorted. My USB cable was naff but a spare one worked fine. That's weird cost I tried changing the cable before. Got everything working and flashed the 21e kdz and it all works great now. AnTuTu benchmark test jumped from around 5000 to 6400 by switching to Prometheus kernel.
Hope that helps you, previously I flashed some small fls and bin files but you have to flash the 300MB file.

But what??? :-( I never installed Gingerbread before. This is my first time. I followed pandaballs tutorials to install v21e through kdz method,and everything was as it shoul'd be. Coul'd it be because i selected another country and language when installing gb? My phone is from Slovenia i think. I live in Serbia,but when i installed gb,i selected Italy,and english language.

Shouldn't be the issue. Try wiping data through stock recovery.
I'll try but i clearly doubt it will solve the gc issue. When i installed v21e i did a factory reset,then i rooted the device. Is it possible that rooting screwes up something?
Sent from my LG-P920 using XDA Premium App
I live in Bulgaria, also i make root with Megatron root!
Steel don't have GC with V21E!
Also my battery works more better with that V21E.
Do wipe partiton and other option wich you can make before root.
I thing only factory reset is not enough.
When you flash phonewith 21E version,before turn on your phone do all wipe option.
this scares me a lot, but for now no ghost call, sorry for my question, but you are sure about the version? 19-apr-2012? You download the rom from official lg site?

That's worrying. You are the first to report ghost calls with V21E. There were two more reports before yours but the first has flashed only the V21E baseband (not the complete rom) and the second was using a custom kernel instead of the stock 21E kernel.
However, I think that there is a possibility that the V21E was not installed correctly in your case because not only you have ghost calls but your battery drains very quickly. This could not have happened, especially when you came from Froyo as you said. All Gingerbread roms (even the ones that have the ghost calls problem) have much better battery life than any Froyo rom. And the V21E has even better battery life than the older Gingerbread roms.
Perhaps the .kdz file you downloaded got corrupted? Or you didn't wipe/ factory reset before and after upgrading to V21E? I suggest to download and install again the 21E following the procedure here.
That's very strange.
In my tests I've NOT been able to reproduce a single ghost call making something like 200 calls on 21E
I've only managed to preoduce some "ghost rings" : a single ring (just the first of the rings) wich hasn't been shown by the dialer app. (Not a big deal however)

Hi guys!
I'm a little new to all this Android stuff and tried to learn how to fix my phone but I've been reading around in circles now for two days and still can't make heads or tails out of it.
I've got a LG P920 Optimus 3D that has stopped working.
Now what happened is it froze like a it had before and didn't want to shut down when I held the power button so I took out the battery. When I turned it back on it got stuck at the LG logo right after the LG sound played.
I tried some sort of LG update but that didn't work then I tried a couple of things I found on different forums something to do with the LGflasing tool or something witch also didn't work (or at least I don't know what I'm doing) and at the end I was able to hold some vol+3d+power and got a recovery menu and wiped everything I could find.
Now the phone turns on fine and everything works except for the phone part. I don't get asked for a PIN and it just says "no network" with any SIM card.
Here's the data from my phone:
Country of purchise: Slovenia
Android v: 2.2.2
baseband v: L6260_modem_sic_01.1042.00
Kernel: 2.6.25.7
SW v: LGP920-V10K-SEP-17-2011
Can someone pleas help me and explain what I'd have to do to get this thing working again because currently I'm out of ideas and I have no idea where to start.
Can I do something on the phone to make it work or do I need to flash something and if so what and how. I'm really lost here and can't seem to make heads or tails out of all this.
Thank you for your help, patience and I apologize in advance for my lack of knowledge in this area.

Use this:

You cant write IMEI with hyper terminal until your IMEI is that strange number. If you cant get it that way with smartflash tool (erase CP). Flash lg prada baseband that will do same thing. After that flash 21e baseband and restore imei with hyperterminal.
Edit: check if you got drivers instaled.

Try a factory reset from within cwm
i think you cant run prometheus, until you have gb on your o3d.First you need to flash it.Use kdz method or wathever you like to do this.
Sent from my LG-P920 using xda app-developers app
I'm pretty sure the fact that you're running froyo is the reason why flashing the rom.did not work. Promethius operates on gingerbread basebands so you need to be updated for the rom to work properly. It would also help if you asked this in the promethius thread lol
Sent from my LG-P925 using xda premium
Did you make a back up before you tried flashing the rom?
Sent from my LG-P925 using xda premium
hello
Connect your phone to your computer using a USB cable
Run Lg Suite
remove the batteries and then insert
you hold the power On end volume up (+)
keep it pressed until lg suite says that the phone is connected
Or you will see the option to upgrade - If yes, update your phone to the basic version
And if it does not display upgrade options
Go to the Emergency Recovery system end typing the IMEI and install - end update your phone to the basic version.

And what exactly did you develop in this thread?
Please avoid creating threads like this in Android Developers section.
Apart from that all necessary information to fix your phone is here
[GUIDES/TOOLS]Making Developing/Flashing/Returning to Stock Easier (Multi-page thread 1 2 3 ... Last Page)
or you can ask for help from Promethius ROM users in that thread.
I think this thread should be moved to general section
Not to be rude or anything but please don't start a new thread every time a single problem occurs. Also, do some searching and reading in the threads that are already there. There's at least 4 guides to do a kdz flash. We shouldn't have to hold your hand every time something happens.
But really, update to gingerbread and that'll clear up 90% of your problems

What baseband are you using? Which version of the rom did you flash?

Hi all!
I have a problem with my LG Optimus 3D. I cannot enable the Wifi, when I tap on the wifi enable icon or try to enable in the Settings it just flashes. A note, I forgot to disable the wifi when I went to sleep, and my phone was on wifi all night, but I think this cannot be the source of the problem.
Here's what I tried so far:
- Hard reset - Wifi not working
- Factory reset - Wifi not working
- Changed the ROM - Wifi still not working (I used this ROM)
Any suggestions ?
Thanks for the answers in advance!
If the wifi is not working in any situation consider to put it back to stock, clean it up and give it to assistance to repair it.Might be a faulty WiFi module. Are you sure that you don't use a fixed IP on the phone or your router is faulty?Just asking...

Hi!
Thanks for your answer! My router is working fine, I cannot even turn on the Wifi on the phone. :/

Well the return to stock and assistance is still valid.Try doing an emergency recovery using update tool from LG.Maybe the new version software- the 2.3.7 version with v21e baseband version, would do something good. Cheers mate and good luck.

This is certainly not the source of the problem. I keep my WiFi always on (from advanced settings, WiFi Sleep policy: Never) which doesn't consume much batter when the phone is on standby.
did the problem occur when you flash the rom ?
in which baseband you had
for example if it was 2.2 baseband and the rom was for 2.3 it can not be flashed with clockworkmod
you should flash the kdz files for 2.3 baseband and then flash a rom with clcokworkmod
i also had problems with wifi and i did flash a 2,2 baseband ( kdz files ) and the problem was fixed
Can someone help me? I got a wifi issue also.... sometime i can't turn it on... and it drains my battery so quickly... and whenever it happens, i have to restart it in order to use the wifi... i think i have a stock rom... i don't flash another rom again since the last rom from thaiz... and there're not a big improve at all...

Sorry my bad I totally got backwards on that. If you are in the US like me, did you alter the build.prop target country from EU to US and flash the V30B baseband followed by a factory reset? If so have you tried to flash V28B baseband instead? If those options don't work my friend I'm clueless.
