plz some one tell me how to make abootloader to it i have another lg gt540 i want to know if i can use it to repair the bootloader for this dead phone

The problem is theres noway u can acces inside the phone memory to patch bootloader. Go to lg waranty and tell them this happened when u were updating phone, dont tell them that pc crashed, tell them u updatet through lgsupport tool too, not through kdz updater they should fix it for u.

can any one tell me what should i do

Remove battery press volume - or + I can't remember try two options, then plug in usb.
You should see blue screen with DOWNLOAD or EMERGENCY MODE text.

i tried all keys combination nothing work

my mobile internet went dead after flashing quarx rom (I did it wrong btw...), but everything else worked fine.
I couldn't get mobile internet back on track no matter what (it was disabled in quick settings when I flashed quarx), I even tried factory reset and flashing the baltic rom. during the flashing, the kdz updater gave me an error close to the end, and my phone became stuck at the android screen.
even though I have CWR installed, so I could flash it again, I sent it to LG claiming I was updating through their website and since my phone doesn't start. I didn't tell them anything about the mobile internet not working. Hopefully they'll clean the phone completely and that will fix it.
I'll be picking up my phone after work today, I'll let you know how it went.

Same thing Happened to me n almost **** my pants for killing my brand new phone..
follow these steps
1. volume +or-(i dont remember) +camera n power on. it should turn on n say downloading mode.
2. update( you can use kdz updater, it probably wont crash this time but even if gets stuck just w8 for it)
3. after updating, remove the usb cable n turn on the phone, hopefully it would work
4. ENJOY ( N THINK TWICE BEFORE EFFING WITH THE PHONE, )
i am not sure about the keys for emergency/downloading mode(i think it was vol-) GOOGLE IT IF KEYS DONT WORK.

Put to microwave on 2 sec without battery and send do service

my service provider fixed my phone in 3 days without any issues, they flashed the t-mobile branded 2.1 on it. went home and now I have the open europe with fastboot and cwr.
so if all else fails, just send it to LG or your provider.
cheers!

Bricked phone ?

Hi,
I tried to upgrade from v2.1 to new Android 2.3.5 Gingerbread For LG Optimus GT540 and I followed instructions exactly, but I am stuck at number 8, I did this:
8- Now click “Launch software update”, DO NOT USE THE PC TO THE PROCESS IS COMPLETE. THE PHONE WILL REBOOT WHEN FINISHED THE PROCESS IN KDZ. (The process takes about 15 minutes in KDZ).
and about 2 minutes text log writes and stopped, I am now waiting more then 40 minutes my phone didn't reboot. On display is still written download mode, what should I do now ?
In kdz is written:
3GQCT: wParam = 205. IParam = 36
p.s.
I disconnected phone from usb and pull out battery and now I cannot turn on phone, I tried to push vol down + power for 5 sec.
Any idea what should I do now? I hope I didn't brick my phone

What programs are you using?
What are you using to update your phone and have you tried taking out your SIM, SD card and battery then turned it on with the USB cable?

I used KDZ updater and tried to install CyanogenMod7 (2.3.5) @ GT540 Swiftdroid2 RC3 by Mur4ik. if that is what you ask ?
I removed sim card and battery also, then tried to turn it on while plugged in to computer usb but no response from phone, I can't turn it on
p.s. I am using win 7 64 bit OS

If you can't get into download mode, then it's game over I'm afraid. What you will need to do is return the phone back to where you bought it. This happened to me some time ago. But the Carphone Warehouse were happy to fix it (even though I had voided the warranty but don't tell them that ). Don't say that you tried to mod the phone, say something like 'I installed LG's PC Suite and it said my device had a software update. I went along with it, but it gave me an error half way through. Now my phone won't turn on at all' It might just work!

I had the same problem when modding with kdz.
completely bricked my phone, but was able to fix by putting kdz into emergency mode instead of diag and updating with a fastboot stock rom,
it would stop after 2 minutes and give me and error but it managed to get fastboot onto my phone,
(camera + power)
then just flashed the fastboot method with adb and everything was fine,
my problem was something to do with lg modem drivers i believe,
I read a thread that said to disable the lg virtual modem. (didnt
work for me)
pretty noob myself
but the above method worked for me,
not sure if this can do anymore damage to the phone

have a look at this is u get it into emegancy mode.
On the kdz updater instead of 3GQCT put into emergancy

If you have tried flashing with Cm7 you might be lucky,
try holding camera button and powering on the phone, a black screen should come up thats fastboot.
if that comes up u should be able to just reflash following mur4iks instruction
if not try what i said in my last post and reflsh with phone type 3QGCT and PhoneMode EMERGENCY
again only going of how i fixed my bricked phone

He was trying to flash a fastboot rom (to install CM7) but bricked his device in the process. So he can't flash CM7-.-

Yeah I know that but I mean when I got the error he has, I flashed with a stock 2.1 fastboot rom With Diag changed to EMERGENCY and was able to get on to fastboot mode (camera+power), I got the error again as i was flashing but the phone would load fastboot and not start up
If he can get lucky and get into fastboot like i did, a simple:
fastboot -w
fastboot flash boot boot.img
fastboot flash system system.img
fastboot reboot
should fix his problem or did i just get lucky?
sorry if im confusing thinks here, but this is how i fixed mine. which was also dead and not turning on

Well like i told you im a noob at this myself (Android phone flashing atleast)
I suppose it would be good to see if you got fastboot??
Power on the phone while holding camera button (hold the camera button until the screen goes black) if you can get fastboot you can just follow the fastboot flash instructions after fastboot -w
if not on kdz in the top right were it says DIAG, Change this to CS_EMERGENCY,Click Launch update and flash again with a stock fastboot rom
after THIS see if the phone loads or boot loops(had this once too) or loads fastboot
Il try look to find the thread i read on another forum for troubleshooting kdz it helped me alot
EDIT: http://android.modaco.com/topic/321895-faqgt540-reference-thread/ try some of the troubleshooting tips at the bottom of the O.P
I basicly aimed to get fastboot working so make sure your flashing with a stock FASTBOOT! rom
again im new to this im just saying what got my phone back to life

I bricked my phone and I tried it again after getting it back from lg

I'm new here and to having a Smartphone, I've just been given an LG Android GT540 which is at version 1.6. The LG site tells me I can upgrade to 2 something or other, sorry can't remember the exact number and gives instructions on how to do the upgrade, but I'm a bit on the cautious side as I don't want to brick it, not this early on in owning my first Smartphone.
I'll be reading a lot of the posts here to try and find out as much as I can before I attempt to do this.

Well don't worry if it's official update. But if you some how brick your phone just tell lg the update bricked your phone and we are talking about unofficial updates

I've got phone today from service (not official LG service), repairman just manage to wake up phone so I can turn it On, but when I turn it I get black screen with message on it ''download mode''. Now computer recognize phone when I plug it, and I tried to update or flash it with kdz updater but have no luck
I launch kdz in emergency mode, load rom with updater, press launch button, and process started, (get messages unpacking software etc.) but after 3-4 minutes I notice that computer is blocked I couldn't do anything with mouse pointer, and I waited 15 minutes but computer is still blocked, even time on computer is stopped. I tried this procedure few times, every time it is same. Also tried to disable lg virtual modem in device manager. Any idea what I could do ?
p.s. repairman in service told me that he tried it to flash it with riff box, process started but after few minutes if stopped and blocked his riff box

Possible bricked device

Im unsure as to whether my Galaxy S is completely bricked.
My Galaxy S is stuck on a screen displaying - Phone ! Computer
I can't access download mode by the 3-button combo or by the USB jig.
Is there any way I can either boot the phone or get to download mode so i can flash with odin.
PS - I got to this stage by accidentally unplugging the device when flashing firmware in odin.

probably the answer is no im afraid if 3 combo AND USB jig isn't working...

Take the battery out for 10-15 min then place the battery and try Download Mode or the USB-JIG and see if get's to Download Mode.

Find someone with a riff box ... if your in the uk inbox me

A friend of mine had a similar problem but the phone didn't show anything on the screen, I told him to do the button combo for donwload mode hold them for 10sec and connect it to the pc with odin open and it just work btw the screen wasn't showing download but it was, give it a try who knows

i try everything in a net coffee installing lg drivers only and used the instructions. yesterday i install and lg program disable modem still no luck. so if phone just doing that noise means that is connect it but how must kdz find the phone if the phone is not installed. (i mean not the lg drivers but the phone when is in usb debaging smth is installed in pc from phone) i search everywhere and everybody can get to download screen exept me grrr is not my phone orelse i will throught it from the window. so if the the noise is ringing means is connectid no need for download screen? thanks you and sry for my english!

you need that sound and download mode unfortunately. try installing new drivers and new KDZ and try again. if not take it to the LG service. do you have recovery installed?

as far as i know its power + camera button.
Hold them down until backlight comes on. If you need it fixed by LG just lie about what happened. Dont tell them it died when you were installing a custom rom. Also from what i understand you cant get it to even turn on in any way? Or connect to a computer?

[Q] [L7][P700][Bricked] Hard bricked Optimus L7 P700

Hey guys,
Yesterday I tried unlocking my phone using the tools provided on this forum, but somehow my device got hard bricked.
It is just laying there with a black screen. It won't turn on, won't boot into recovery or emergency mode. Nothing.
But when I connected it to my PC (running Windows 7), I did hear the sound that it recognised it as a device, it just couldn't find any drivers for it, so I wen't to look into that.
Landed on the debricking method using QPTS on the CyanogenMod forums and I managed to find drivers for Windows 7, so no need for an XP computer!
There were some other Optimus L-series brickers who gave up on the process, but I have still some hope left.
Did all the work that had to be done, decompiled V20D KDZ for our device, converted the first 512 bytes of the partition.bin to .mbn, installed QPTS, and so forth.
Hooked up my phone to the pc holding the volume-down button, and QPTS actually recognised it as a phone in downloading mode!
Then that's where I got stuck. Using the HEX files from this thread, I get the following error:
Code:
Status: Software Download Aborted
Errors: Could not determine the HEX file's scrambling method. The file is invalid.
Do any of you have a clue on how get things working again?
The QPTS tool only lists MSM7x30 (eMMC) as ARMPRG to use for the phone in dowload mode, not the MSM7x27a we are using. Might this be part of the problem?
Any help is highly appreciated!

Can you go to emergency or download mode?
Battery taken out, hold the vol up + connect to usb, connected to the pc. Then you will see in a green screen with emergency mode.
Once your done that, be sure you installed the LG drivers, flashed through kdz.
You can use homero's v20 stock, it's already had cwm and unlock bootloader and v20 baseband.

Nope, can't get into emergency mode, screen stays black, no matter what. So yeah, just flashing a new KDZ isn't an option. :crying:

Does the kdz flasher recognized the phone? If it's turn on and connected to the PC.

You should try launching emergency mode some more. Install lg drivers. Take out battery, hold Vol up button and plug in usb. Make sure port works.

I can't turn the device on. When I connect it to the PC, Windows sees the phone as an 'Unknown Device', even with the latest LG drivers installed.
And by KDZ flasher you mean the BC2App, right?

Tried it a dozen times, with different combinations too. Only thing that happens is the sound windows makes when a device is plugged in.

Any chance a method like this would work? If the .img.zx file would be edited for our device ofcourse.

Hey all,
I couldn't get any further debricking my phone myself, so I just brought it to a repair shop. I'm hoping they can do something using JTAG or something.
Regardless of getting my phone working again (hopefully), I would still love to see if we can find a way to debrick hard bricked devices. If we can find a solution, I'll volunteer for writing a tutorial
