[q] ice cream sandwich downgrade to 2.1 - GT540 Optimus General

Hello Xda-Developers and LG GT540 Users,
recently I flashed my GT540 to ICS by mikegapinski by fastboot method.
The phone was running on out.kdz.
I found ICS to have few bugs on my GT 540, so I flashed it to V20A by using KDZ.
Then flashed it to out.kdz by using KDZ.
Now the phone is stuck looping at Android logo, and fastboot mode is not available, only download mode works. KDZ doesn't recognize the phone now, "PHONE NOT FOUND", so I am unable to reflash it.
I tried the method at http://forum.xda-developers.com/showpost.php?p=10238074&postcount=41, but KDZ updater says "Phone Not found".
Experts, I need your advice to save my bricked phone, please help.

hi there,
can you try booting into recovery?? power+home buttons
if that does not work try this methods
http://forum.xda-developers.com/showpost.php?p=13205397&postcount=26

Recovery doesn't activate. Yes I tried all the methods in the thread you posted, including disabling lge modem etc.
I am able to get into download mode, but KDZ updater or my computer doesn't recognize the phone at all. KDZ says phone not found and the computer doesn't show any device connected either.

reboot into fast boot if it's still available and run
fastboot -w
Then reboot
If it doesn't, boot into download mode and flash a fastboot kdz and try again

Fastboot doesn't show up at all. It gets back to the looping android logo, even if i try the keys for entering fastboot (which worked earlier prior to flashing)
Download mode works, but KDZ doesn't recognize the phone at all!! "Phone not found" keeps appearing.

No, I tried cs_emergency, it doesn't work...

maybe try to reinstall drivers and then try again in download mode and in kdz cs_emergency

its not driver prob he flashed kdz before....

You should open Device Manager to see if your PC recognised your phone properly. It should be in Universal Serial Bus Controllers.

I started up the phone in power+volume down = download mode. The PC installed the drivers and it shows in the LGE Composite drivers. However KDZ says phone not found?

I managed to flash the V20A french kdz to the phone.
The phone is now stuck in the android logo boot loop.
What to do next? Please tell.

SOLVED
Okay I finally got it back to working condition by this method. It is for future reference for someone if they are in the same situation:
1) Erase all the drivers of the phone in your PC. Including LGE modem, Android composite, ADB Spooner etc.. and reinstall them using Windows auto update feature.
2) Get phone to download mode and flash V20A and out.kdz using KDZ in cs_emergency
3)That's it phone is back into working condition.
Also, the ICS by mike gapinski is a great rom, but the lg gt540 is too weak to run it. It runs into several errors, most processes stop responding, so the gt540 is too weak to run ICS yet. My 2 cents.

BootLoop -> Solution:
- Boot into fastboot.
- Flash latest recovery (5.0.2.7) (fastboot flash recovery recovery.img)
- Use commands:
fastboot -w
fastboot erase system
fastboot erase boot
fastboot reboot​- Boot into recovery (now you will can do it, 'cuz you flashed it previously)
- Flash another rom, like PCF v5.
- Now your phone will boot correctly.
- To flash 2.1 try don't use kdz, you can brick your phone doing that. There are lots of very goods 2.1 custom roms...

Or you sholud try another computer...

the best rom for gt 540 is by mur4ik 2.3.7 .tested , 100% stable.mine run on 825mhz.

[Q] Downgrade from 2.3 to 2.1 failed

Hi
I have installed SwiftDroid v2.0 rc5 fastboot and after it i wanted to go back to android 2.1 using KDZ UPD, but the phone stopped working. When i try to start it, it vibrates but nothing else happens. It starts in download mode (with and without battery). I was trying to flash it with KDZ updater in emergency mode (with different ROM's) but at the end i get error: TYPE_WPARAM_UPGRADE_ERROR Error Code = 6. KDZ updater and LG Mobile Update recognize the phone but fastboot and adb not. Any idea what to do now?
All i know is that you don't have a boot animation. Try to fix that first:
http://android.modaco.com/topic/327768-no-boot-logoanimation/
How about a different 2.1 rom?
Or maybe u havent turn off android modem yet
as i wrote in my first post, i was trying to flash it with different roms
modem is disabled
i send it to lg service
I downgraded about 5 times using kdz and i never stuffed it up

ok so why the bloody **** not just load into recovery menu from boot and reflash swiftdroid fully?

[Q] Soft-brick? ADB sees the phone.

Hello guys, I have a problem with this phone.
First I flashed the euro+fastboot kdz... The phone booted and worked awesome but It wasn't showing recovery or LG logo.
Somewhere on this forum I read that you had to flash v10c and then v20B to fix this.
I did so, v10c failed, but v20B flashed correctly, but it didn't boot up.
I'm still stuck here, the phone is completely dark, but when I connect it to the pc I can see it with ADB, It just doesn't go into fastboot mode (because of v20B I guess). But flashing the euro kdz won't work anymore, and I'm stuck in ADB without fastboot.
Hope you guys can help me,
Juxter.

So after 4 5 6 or maybe 10 times, it will finally become working, that's what you're saying?
This is really odd, something's wrong with these phones lol
Okay, i'll load myself with a ton of patience and repeat the steps as per the instructions. This is *exactly* how i am doing it, with all the details:
1) Using the French v20A ROM - http://csmg.lgmobile.com:9002/swdata/WEBSW/GT540/ANEUBK/V20a_00/V20A_00.kdz and this Russian one - http://narod.ru/disk/25473801000/out.kdz.html
2) Take out the battery, SIM card and SD card
3) While holding the Vol - button, plug USB into phone so that the phone goes into Download Mode
4) Run the KDZ Updater, put it into CS_Emergency mode
5) Select the French V20A rom and flash it
6) When it's finished (immediately after the DOWNLOAD MODE letters vanish), i pull out the USB plug from the PC, so that the phone doesn't boot.
7) Again hold Vol - and reinsert USB to put the phone back in Download Mode
8) In KDZ Updater (still in CS_Emergency mode) select out.kdz and flash it
9) Let the phone boot into Android
At this point i STILL don't have a boot animation, should i keep doing this until i see one appear?
When it (if) finally appears, i just flash my own ROM, do a factory reset and it should stay that way, correct?
I guess my impossibility to access recovery mode also has something to do with this...

Note: For above step: 1) Using the French v20A ROM
-- as long as you have the ROM of v20 with fastboot option, it doesn't really matter.

Thanks for the reply, I actually fixed it following this:
hxxp://modaco.com/topic/329863-how-to-raise-gt540-from-the-dead/
Once I got fastboot with that cwm.kdz I reflashed a fastboot rom, and from that one I could use the KDZ updater again, following the French kdz procedure...
The phone now is fully working recovery and bootanimations again

Bricked G2 - Fastboot only/No download mode (Beer money for anyone who can help)!!!!

Hi Guys,
I brought my LG G2 D802 32GB last week and I believe it's possibly hard bricked if not soft bricked so let me start by saying that anyone who can help me get my brand new G2 working will be receiving some beer money!
I've owned over 15 android devices over the years and i'd say i'm a competent flasher but I've never had such a problem flashing any of those devices as I have on the G2!
So here's what I did:
1) Updated Phone to 4.4.2 and rotted using IOroot method (Root was successful)
2) Install LG USB Drivers
3) Flashed CWM 6.0.4.4 (Flashed successful and CWM was working fine with Root access on ROM)
I then decided to put TWRP as the recovery because after much research it seemed to be the most popular choice.
4) Downloaded D802_AutoRec.apk (I believe this was the correct recovery for my device)??
here's what happened:
After using AutoRec to flash TWRP recovery I rebooted and the phone displayed:
450 Fastboot mode started
500 udc_started()
Plugging in the USB cable then adds the following lines:
660 -reset-
670 -portchange-
740 fastboot; processing commands
Note that Download mode WAS available at this point.
I then tried flashing CWM recovery again through fastboot which showed as successful but still stuck in fastboot after rebooting. The same happened for TWRP.
I then went to the LG website, put in my IMEI number and downloaded the stock ROM (D80220C_00). I used the G2 extractor to extract the kdz to a DZ file then extracted the aboot/boot & laf.img. Since I did this I have lost download mode!
It's interesting to note that fastboot shows attached device as:
? fastboot
and ADB shows no attached devices.
I'm not sure this is relevant as I still seem to be able to push commands to the phone through fastboot?
I then tried to flash the stock ROM (D80220C_00) using LG Flash Tool however it gets to 27% and says "cannot connect to the phone
So as it stands at the moment all I have is the option to flash using fastboot, I have no download mode, no recovery or no working ROM. Have I completely bricked my phone or is there anything else I can try to get the stock ROM back on there?
Any help is massively appreciated!
Hello!
Try this, I hope it helps!

Did you try Tot method? What happens when you plug your phone to pc? Does adb recognize your device?

How can i try tot method without going to download mode ? as i said phone only have stock recovery , Yes there is an option in stock recovery "Apply update from ADB" by selecting that i can run adb sideload commands. And i can flash any zip rom from that option . I tried several rom's using this option but installation aborted in middle .
Does device manager in Windows recognize your device? In Tot method you do port settings to flash kdz. Also you can give it a try for LG pc suite.

D800 broken download mode

I once bricked my phone by installing a L01F ROM on my phone by accident, and had to manually reflash every partition in windows CMD prompt. I have been using my phone fine since I recovered from the brick but I was going to tot to stock and update to lollipop but my download mode says secure boot error and shows up as qhsusb_bulk in device manager and gives me a ton of partitions. I have been looking around for a solution but cannot find one. The only thing that is broke is my download mode. I have recovery and a booting ROM.
