[SOLVED] Possible brick after Smartflash

ok you guys have to help me fast!!!! i did this guide http://forum.xda-developers.com/showthread.php?t=1629307
ive done everything correct the download window appears and it says downloading complete and erasing something and so. it looks like its finished but it only went on for a couple of seconds everything was green. Should'nt it be like a progress bar and take some little more time? i thougt it was finished so i closed the download window and clicked start again but it says
ownload Start...
:We cant communicate with specific port and there is a big error.
The device isnt recognized in device manager.
I havent disconnected the usb yet becouse am afraid that if i do so the phone will be bricked!!
P.S ive just had it back from repair.

please any1? i will be so thankful for any answer. ive read all the recovering from brick guides but that requires you to disconnect the usb. I wonder if there is any solution when i havent disconnected it yet?

if :We cant communicate with specific port occurred before flashing started imo you should be okay pull the usb out and try boot the phone see what happens

But the first time i did it it said download complete and then it erased AP or something but the whole process only took a few seconds and then when a thought it was finished I closed it down. But then i thought when it said erasing and then erasing complete it maybe just erased the system bootloader and everything so i clicked start again and the error appeared.

IMO it is better and easier to use the kdz method that the dark lestat posted in development section

Should i disconnect and try to boot? Or is my phone hardbricked?

Haha I booted up my device and it worked but it didnt have a signal. I think smartflash only flashed radio so i will install a 21e rom and kernel.
Sorry if I bothered you guys ^^. Mods can close this thread

Disconnect Everything remove the battery for like a min pop it back in and switch on see if it boots.
If it boots use KDZ method
IF No boot try Flashtool again restart pc also

Ok so I installed prometheus rom + kernel but it has no signal it doesnt dect SIM. I think smartflash just simply erased all the radio software.

I disconnected it and was terrified that it was hardbricked but i could boot it to the lg screen but i could not enter recovery. I know that you can easily restore a logo brick but will do that tomorow.
I will NEVER try to flash anything again!!

Don't give up just yet! Look what you just did! You recovered your phone after you thought it was beyond your ability to do so. What you ran into is a near worst case scenario and doesn't happen that often. If you have ClockworkMod Recovery installed on the phone, just download your desired ROM and follow the steps for flashing it through there. You can do some great stuff with custom ROMs and you've already proven you are able to handle the problems that come with it. Don't think of it as a mistake, but your first lesson.

[Q] Can someone PLEASE explain...

I`m on gingerbread now and i want to use smartflash tool to flash ICS and vice versa! installed lg drivers, installed OMAP drivers and everything needed. How come that every time i come across smartflash procedure, it only says flash .bin file and that`s it. Sort of! Why not .fls file too? It is baseband, right? So i`ts important. ICS is different partition and bootloader and i just don`t think that flashing .bin file is enough. And also, is it a problem that on smartflash says P990 in phone model and can`t be changed?? I had P990 before this phone and smartflash is not unknown to me. I know how to use it but i`m just very confused about p920 and smartflash combo!

I must disagree! ) Smartflash is way easier, only if i could figure it out how to use it with this model or someone who already flashed 3D with smartflash to explain a bit how to! Nonetheless I use win 7 x64 and most procedures are for XP, and those few that work in win7 are way complicated for my degree of expertise! I used to perform miracles with p990 but this one is with no reason far more complicated

I used to think this stuff was hard until I asked around and got help. It's a piece of cake flashing KDZ's. Windows 7 procedures are almost identical to the XP procedures. The only difference is that you have to go directly to the Device Manager to install OMAP drivers rather than getting a pop-up and installing it from there. The hassle is Windows 8, that took me a few hours to figure out because it checks driver signatures.

From what I read, .bin file INCLUDES .fls file. So flashing bin will give you new baseband.
You can check your current baseband with app GetRIL (use it only for checking!).
Flashing fls is needed only when you mismatch ROM and baseband - in Canada the best results are with v20c bb. So then that fls should be flashed after bin file.
Hope it helped

I see your point, but what i really want to know is, is there a difference between .bin for p920 and lets say .bin for p990!? Sounds weird, offcourse there`s difference , but i`m asking just because when i was flashing p990, it`s necessary to put both bin and fls to smartflash and then start it up!
For example, this is what comes out from unpacking v28b.kdz file for p920
http://img32.imageshack.us/img32/8830/35283994.png
So there is fls file after all... And that is what confuses me the most! So.. what i really need is for someone who already flashed this phone with smartflash to give me step by step instructions, with no exceptions from ABC~Z. I would really be grateful besause i don`t want to install XP every time new SW comes out.

Unfortunately the only procedure i`m familiar with for flashing kdz`s won`t work in win7 x64! For me at least. It crashes every time on the beginning of extraction of kdz. Luckily not later But i know for sure it works in xp and as i said before once, i`m not gonna install xp just for flashing my phone. So i need a little (detailed ) help with smartflash. :angel:

So, did you try flashing 920 bin file with LG SmartFlash?
I did it on Win7 x64, no XP needed
Did you check drastic00 guide? It simple once you do it couple times
It's really hard to give EXACT step by step instructions since nobody kbows what you already have on your PC (driver wise
So every guide starts with: uninstall ALL LG related drivers...
Please read the guide THREE times (I learned it loong time ago).
Then ask questions, if needed.
Good luck!
PS. I've never dealt with P990, sorry.

I didn`t flash anything yet because i`m not sure. I only want simple procedure so i can restore my phone if something is wrong with it, and this smartflash situation is driving me crazy! A can`t dare to use it and flash, honestly, because no one actually gave me green lite that it`s safe enough.
http://www.youtube.com/watch?v=uCHRwKGTZTk
Can i get confirmation for the same procedure for p920? I REALLY don`t want to brick my phone since already i`m having trouble figuring out how to flash sw and not be able to recover it in that case. The only difference is the way to put phone in to download mode! And the fact that it says p920 in model line confuses me even more! Is it safe???

p990 and p920 use same procedure and dont be afraid of bricking it the resurrection guide unbricks it

So i can use both bin and fls in the process? The guy in the video used them at the same time so i guess it`s ok for this phone too because i read somewhere that they flash separately!? First bin, then restart and then fls! What`s the difference? And one more thing... In another video, guy also used smartflash but this time he was actually flashing p920 and he used something called windows enabler! What is that and is it necessary for process? Here`s video link...

Would this lock my phone to Rogers? Or would it remain unlocked? I'm curious because it doesn't work well in canada right now and I'm with telus. I have a p500 that locks onto the Mikes tower just south of where I live. The p920 doesn't do it as well. I'm on v21e Right now and need to change it. Thanks

I used to flash Gingerbread files with smartflash all the time, however it never flashed the baseband correctly for me so I would use LG flash tool to flash .fls files. That being said I have only flashed V28B and V30B files with LG flash tool because I thought I read somewhere that smartflash wouldn't work...maybe because it doesn't do the baseband correctly and the baseband for ICS is included in the bin file. Either way flashtool and smartflash were easiest for me, I find it much harder personally to do the KDZ method. I did something way wrong in the early days of the KDZ flash method that had some shttp server file that completely crippled my internet and I've never got my cpu to connect since. I use to just extract and merge the bin and fls files from my KDZs with LG Extract lol.

In Canada baseand v20c gives good results. Also with latest ROM based on v28b I use v30b baseband.
Try couple of them.

What exactly do u mean by this!? What happened and how did u noticed it?
edit:/ Just flashed v30A with smartflash and i used windows enabler (what ever it is for), and the weirdest thing is that after restart, all my applications and settings remained unchanged and only thing that is different is software information in settings! Oh, and camera shutter sound OFF is gone too. That sucks! I used to flash p990 with smartflash and every time phone goes back to factory state after restart because it is flashed again, right!! But now it`s just like i updated it via LG Support Tool. Just updated. Don`t really understand! I used both bin and fls files in process.

Bricked?? Please help

PLease help ... I flashed XBSA v8 rom..then when i was about to reboot I accidentaly Hit the install zip from sideload...I didnt know how to get out so i searched and found out I need to hold power button for long period of time...it worked..when I turned on my phone it is stuck on LG Logo.. I was trying to get in recovery mode but I cannot..I didnt know exact combinatin so i tried both 3D button +power +volume down and 3D+power+volume up... I saw some guides but I dont understand them...PLease help...And If i ever get out of this should I try reflash the rom? Please help

follow the ressurection guide. or remove and reinsert battery hold volume up and power button if you saw Sw download mode you can reflash back to a stock firmware using lg flashtool

No need for resurrection guide.
Use drastic00s noob guide and you'll be on rooted V8 with TWRP recovery, in no time.

Thanks for fast replies.. I already did it with the panda ball guide Im not sure if that is his exact name.
problem is that I cannot call phone says I have sim not inserted. My internal memory is 0.00 b so I cannot install ROM manager to get out of this
. After this flashing through PC do I still have my root and CWM ? If yes is there button combination to get in recovery? Btw there is notication going on every 20 seconds saying not enough space try again please help

I don't know who panda is or his guide but I can recommend you to follow drastic00s guide and you'll have V8 with custom recovery and root.
Be sure to flah xbsall v28b rooted and on top of it v8, like the guide says, so don't jump over some steps.
Do it step by step from the beginning.
Edit:And don't use rom manager, you don't need that.If I remember correctly It can brick your phone so don't use it.Anyway there is no need for it in the first place...
Edit2:When you flash V8 you can enter recovery like this:
1. When you power on or restart the phone, while the soft keys are blinking pres VOL-
or
2. Via P940 recovery app from your app drawer while the phone is booted(that app is installed with V8)

Can I do it even when my phone has the stock firmware?

Yes.
LG Flashtool is used to flash new .kdz firmware over any other firmware.
It doesn't matter on what android version you're now.
That means in the future you'll use the same guide to flash official v30b for P920 when it comes out.

Since I need to get phone working fast I need a really big research for everything about the rom and stuff (and found out people hate geting questions through PMs) .. I am right now in the process of installing the v28b but the LG Flash tool port 1 doenst show Ready when I clicked the arrow.. I dont have idea what went wrong I was doing everything as there was written..I used version 1.1..And Do you Use XSBA v8 rom? If yes how is your battery life because I just noticed that in the video battery life is poor... 1 percent for 1 minute.

In which video you have seen that cause V8 video is with power cable...

Ok ok ok, don't worry.
If it's detected by pc than it's fixable.
Follow this guide:

It's explained really good how to use LG Flashtool.
By the way you don't need to flash rootedv28b and v8 if you dont want to, you can flash official v30a if you're in EU or v30b if you're in US instead just use the guide to learn how to use the tool.
Official Open EU v30a can be downloaded from here:

US AT&T v30b version can be find on this forum also so use the one you need.
If you want a custom recovery use OS_Hackings tool and you're done...

One more thing, if you reaaaaaally can't get the LG flashtool to work you can try this:

Just DON'T flash the P920_GB_v30a_00.kdz, instead flash the one from my previous post because the P920_GB_v30a_00.kdz was the leaked ICS at that time.
