[q] problems with lg gt540

hi guys.. could you help me with my problem.!
I have an LG GT540 android 1.6 firmware version(stock)
So here are my problems:
1. I tried to upgrade it from 1.6 to 2.1 using this tutorial http://forum.xda-developers.com/show...27&postcount=3 thanks to lavero.burgos for posting it, I was successful at first part, but I cant follow the next because my device wont go to fast boot,, I tried putting it off, then camera+poweron but it doesnt do anything. It doesn't light, no lg logo appears, just nothing although the computer can read the drive when I connect it through usb. So I cannot flash it to 2.3,2.3 because it just wont go to fastboot.
2. When I turn it on normally, It takes long before it response like after 30sec to light, but just light, no lg logo appears although it wasnt bricked because I can use it normally after just waiting to on.(annoying)
3. Since I upgraded it to 2.1, I lost all 3rd party application and the internal apps were the only left, so I copied all my saved apps (.apk) to my sd card but the problem is there is no saved app on my phone to read and install those apps from my sd card.(irritating)
4. My device wont read my sim card, when I start it it says "sim card unprovisioned" so basically I cant connect to mobile networks here in the philippines(im using globe telecom). I feel that Im stucked in the middle of nowhere since I cannot contact and txt all my family and friends.
5. I cant connect to wifi,, when my device detects wi-fi, I try to connect to it but from the log it only try to connect but doesn't obtain the ip address. Even when the wi-fi signal is strong, it does the same thing.
So please help me guys,,I want to hear from my fellow xda-developers badly,,,
PS. also those who have problems with their LG GT540 pls feel free to post and share it with us here... thank you all guys in advance....

C:\Desktop\adb rebootloader
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
error: protocol fault <no status>
C:\Desktop\fastboot flash recovery recovery.img
< waiting for device >
Did I miss something???

yeah I installed the drivers...

hmmm maybe there are no fastboot drivers(main suspect....) there are a few ways to get it but for mine i just plug my phone in to my pc (windows 7 64bit) it just recognize it and tries to get the "google fastboot interface" drivers from windows update...

Try Volume Up+Search Key+Power to go into Fast boot Mode, There's different keys to activate Fastboot Mode (There is different versions of Fastboot)

Your phone is/was bricked
Hey, I'm sorry to bing back such an old thread, but I just wanted to say this for posterity: your phone has/had a soft-brick. This means: you can't see Android nor LG boot logos, can't enter Recovery and (maybe) can't access Fastboot, but I'm not too sure on that last one. Besides that, the phone works "okay", but you should try to fix it.
Basically this soft-brick is almost always caught when upgrading from 1.6 to 2.1, so everyone should have it, including me. It took me a whole year to realize how to friggin' fix it lol, but here goes what I did:
Thanks for your help everyone, I came to a solution after a full year lol. Here's my enlightenment, from another Thread:
------------------------------------------------------------------------------------------
Just wanted to leave my 2 cents here, I've been trying to do my best since around august 2014, no success. 2 days ago I retried this, and I DID IT! I will tell everyone what I did very shortly:
My problem that I solved: I can boot, device works like a charm. But: no boot logos, no recovery.
My solution for TL;DR: UNINSTALL ALL DRIVERS FROM DEVICE MANAGER 1ST, then reinstall. After that, flash a fastboot ROM and use it to WIPE ALL THE DATA IN YOUR PHONE! THIS was what I needed and was never explained: you had to WIPE the old data in order to get the boot screens back.
IN THIS ORDER (THANK YOU to those people from previous replies, gathering all your info was of great value):
Uninstall all of your phone drivers from your PC!!! This is what made most of my headaches go away, just use Device Manager and uninstall anything from LGE. After that, plug in your device in your USB ports (always BACK ports, not front ports, important). It should detect all drivers and download them.
IF it fails (it generally does with LGE USB Modem), you can go to Device Manager > Unknown Device (the one that wasn't recognized) > Right Click and Update > Choose 2nd option, then choose "choose from a list of local controllers" (or whatever the button says). After that, scroll down to LG Electronics, Inc. and install what didn't install.
I also found these drivers, but I did not test them: http://www.mediafire.com/download/p693hcz6kkouh19/USB_Driver_LG_GT540.zip
Huzzah!
Now you're set to begin:
FIRST thing you wanna do is a factory reset, this is something I'd forgotten with time, don't make the same mistake as I did. You can do it by turning your phone on and pressing Volume +/- & Home & Quick Search buttons all together for 5 seconds (it works, be patient and wait for it, even if you open the camera or any other stuff).
Download this Google SDK Tools (unzip and put the folder in C:\ drive) and this Fastboot drivers for GT540 (unzip and put the files inside the folder in C:\android-sdk).
Skip this next line if you know your ROM has fastboot.
Now, if you don't have a ROM with fastboot, I recommend you use either European Open+Fastboot or V20C Orange France Fastboot ROM.
Click to expand...
Click to collapse
Since you have Fastboot enabled, now all you need to do is turn off your device (all this with its battery on it, no weird things) and hold the Camera button before turning it back on. This should take you either to a black screen, or simply to no display, like me. Either one will work anyways.
Now press the Windows key > Type cmd and open it with Right Click > Run as Administrator.
In it, type all this, command by command (you can paste by right clicking):
cd C:\android-sdk
fastboot -w
fastboot erase boot
fastboot erase system
fastboot -w
fastboot reboot
Click to expand...
Click to collapse
And now it's go time! Do what everyone else says in here: Take out your phone's battery, SD and SIM cards, fire KDZ Updater up as Administrator (If your KDZ freezes, then it's either faulty or you did not install msxml, look for a good KDZ that comes with that file and delete your current one), choose CS_Emergency PhoneMode and:
1-Plug your phone while holding the volume DOWN button (don't worry! My phone didn't show "Download Mode" either, if you hear the Windows "Somethingpluggedin" Bump noise, it's ok).
2-Flash French V20A
3-Unplug your phone once KDZ says "==FINISHED==".
4-Plug it once again, holding the volume DOWN button.
5-Flash out.kdz (remember! it's CS_Emergency).

THANK YOU XDA!

Yep. U can

How can we use the Cyanogen recovery to install supersu without unlocking the bootloader. OR
can any one create a .zip which can be flashed to unlock the bootloader from cyanogen recovery and then root it.
your help will be highly appreciated

I am also facing same problems. Phone is not detecting from PC in fastboot mode.

Hello, the bootloader needs to be unlocked in order to flash super user. The best and easiest way of unlocking the bootloader is using fastboot and a computer. Link mentioned in the previous post.

Hi i can help you with rooting.
I also rooted my yu few days back. so just contact me whenever you want.

Phone boots normally but can't enter Fastboot, no recovery.

Hi guys, I'm having a weird problem with my zenfone 5 (a501cg). I have searched a lot but still can't find out a proper solution So I post it here and try to provide as much information as possible so hopefully developers at xda can help me.
My phone is rooted and I'm currently using modded rom called "bazzrom pinaslang" in the forum. Recently I want to use another rom so I decide to use adb sideload again.
However, the problem occurs: using adb sideload only show "error" message". BUT Adb devices show the phone.
Then I decide to use adb reboot fastboot to enter fastboot. But the phone only show a usb icon, and using "fastboot devices" doesn't show the device anymore.
I try other way by enter recovery mode "adb reboot recovery". The phone show resting android with "no command" message. I also try hold power and press down volumn after that but nothing happend. I try anything with that "power" + "volumn" combo but nothing happend (or it just shutdowns the phone).
Also, using "power" + "up volumn" to enter Droid boot doesn't work.
Driver is install. In device manager it shows "Android composite adb interface".
The only good news is my phone still boots normally and I can use it. Please help me get back my fastboot so I can upgrade my phone to Lollipop and other modded ROM.
Thank you so much !!!!

In that case, follow the "Last resort" part of this guide http://www.asus.com/zentalk/forum.php?mod=viewthread&tid=33800
It will reinstall your fastboot when the USB icon appears

Hi dgadelha,
I have seen your link before my post, but I still wonder because the "last resort" in the link is used for "bricked" phone or the one that doesn't start up or stuck in somewhere. My phone can still boot and use quite normal : ( except one thing that my sd card always unmounted in this Pinaslang modded rom.
TG.

UPDATE I decide to try xFSTK but my computer still recognizes the device as "adb..." . if I turn off developer mode it becomes "portable device" in Window Device Manager.
The xFSTK can't recognize any Cloverfieldplus. (it shows "CLOVERFIELDPLUS...: 0")

Hi,
Because the last resort will use a hardware function (xFSTK way) to update your dnx, ifwi and fastboot images. This way you can restore your fastboot.
Thanks.

You must instal the drivers it mentioned.

Hi techgeard,
Looks like it's a driver timeout.
Which OS are you using? I see they used Windows 7 or before on the tests.
Also you should try getting xFSTK developers (on SourceForge) to help about this issue.
Thanks.

Jiayu S3 3Gb boot loop, i can only access to fastboot

Hello everybody !
I 've spend a long time on this forum and i've found a lot of interesting and useful tips.
I'm in a bad situation today and I can not find a solution so i thank you for the time spent reading this.
Yesterday i've seen an icon on my desktop and i couldn't remember what application it is. I clicked and it was the beginning of an endless nightmare... A huge lag began by making the phone unusable and apps was installing one after one...
When it has calmed down a bit, i tried to install cleaning softwares but i couldn't do anything so I tried to do a factory reset. After that... the malware was still here... So i've decided to clean all by installing a new ROM.
This is a Jiayu S3 4G 5.5 Inch MT6752 Octa Core RAM 3GB 1080P Screen Dual SIM 4G LTE Mobile Phone (invoice description) so i wanted to try the CM12.1 for Jiayu S3 (found on needrom).
My phone was Rooted and TWRP was installed so i've copied the ROM files on a SD card, rebooted in recovery mode, wiped cache, data, dalvic and system and tried to install the new ROM. it was abnormally rapid and now the phone bootloops.
The only thing i can do is activate Fastboot (if i choose normal boot or recovery it continues to bootloop).
I've tried to flash recovery with :
fastboot flash recovery recovery.img
but i get an error message : FAILED (remote : partition 'recovery' not support flash).
Does anyone has ever been in this situation and solved it ?
Thanks for your help !

Hello,
I got exactly the same problem. Did you find a solution?
My phone is in a bootloop, I can only access to the fastboot mode. (fastboot devices show my device).
In this mode, I can't flash my recovery.img:
fastboot flash recovery recovery.img --> partition 'recovery' not support flash.
I can't see my device with the command adb devices (adb devices doesn't show my device, I think because USB debugging is off, but i can't switch it on)
Did someone find a solution ?
Any help would be appreciated, thanks !

That's the behavior of a wrong preloader that was flashed / malware that affected preloader.
Grab a full spftools ROM set, and flash the entire ROM using " upgrade mode"
Cheers
PS: on s3 you need to have both volume buttons pressed, then you can press download on the spft.
PPS: this will destroy all of your data, so back it up first ..

Thanks for your answer.
So, I downloaded latest version of Flash_Tools, but i can't find any complete set for flashing... only recovery.img (I'm searching on needrom.com). Do you have a place to find these?
>PS: on s3 you need to have both volume buttons pressed, then you can press download on the spft.
I think i got another problem: with Flash_Tools, I'm unable to flash anything to my device... There is a special mode to launch, as you explained, but it seems I can't access it... By pressing both up and down volume button, the phone should boot on a special mode ? How can I know if the phone is booted in this mode ? The USB cable must be plugged before/after booting the phone in this mode ?

There is no special mode, please serach the forum on how to use sptools, i am sure you will find plenty of them.

Sorry for late answer !
Thanks for this advice, i will try as soon as possible and post if it's ok or not.

Hello everybody !
Ok, I got it !
My problem came from the drivers... But not the ADB drivers, the preloader drivers.
In the Windows device manager, when I plugged my phone (previously swithced off), I got a "MT65xx Preloader" device with a warning. Be careful, this item stay 2 or 3 seconds before disappearing ! This driver wasn't installed correctly, that's why Flash Tools didn't worked for me (it didn't see my phone) !
So, I got the driver on the web, by typing "MT65xx Preloader driver", I got the drivers that I installed. This guide gave me the files and a method to install them:
http: //laurentiumihet.ro/sp-flash-tool-mediatek-mt65xx-drivers-download-and-installation-guide-including-bricked-devices/ (can't post links, delete space after http: )
To install the driver, you can set up manually by right clicking on the "MT65xx Preloader" > "Update drivers". Then, browse to the drivers you previously downloaded (a folder containing .inf and .sys files). Windows should detect the driver and install it.
To check if the preloader driver is correctly installed, power off your phone and unplug it, them plug it. Instead of the previous "MT65xx Preloader" entry, you should now see a "MediaTek PreLoader USB VCOM Port" under "Ports (COM & LPT)" (same as before, this item is displayed only 2-3 seconds...).
Now that the preloader driver is correctly installed, Flash Tools works for me. I successfully flashed a new rom I got from needrom.com (a full set, as suggested by superdragonpt), and my phone boots now =)
Thanks all for your answers ! Xehon, hope it will works for you !

Thanks mick605 !
I travel for work so i can't try all the advices on this forum atm.
I'll check this when i get back home and i'll tell you if it's ok
Thanks again !

Hy bro.
I m having same problems two days ago.
I found the solution which issuccessfully working for me. First : downloade the universal necked driver (google it mostly found on google nexus 5 thread).
Second : change ur phone's battery. Get a new battery.
Third : remove ur batterry. Reinsert ur battery. Press volume down & connect USB cable u see the fastboot mode release volume down. Then go to device manager in ur computer and search unknown driver. Right click on it and select update driver update it manually ( google it how to manually update driver) browse the necked driver & select winusnb.inf then select Asus fastboot interface ur device got connect. Now flash official stock cm11 firmware through ygdp tool. That's it. Sorry for my bad English.
