[Q] Return to stock rom (LG GT540)

Hello!
I got cyangenmod 7.1.0 with swiftdroid and now I want to return to stock ROM. I tried this tutorial but without success, when I plug in my phone and press start nothing happens. Is there any easier way (for noobs)?
I got LG GT540.
Thanks in advance.
Regards.

solution software bricked
After flashing with stock rom v2.1 successfully using kdz updater, the phone was stuck on boot logo or there was infinite boot load cycle (depends of the stock rom used).
Now, if you have software bricked LG GT540 before becoming another brick of your house try this:
1. Install Android 2.3.7 Gingerbread Cyanogenmod 7.1 using this
Code:
modaco.com/topic/344369-2nov11-android-237-gingerbread-swiftdroid-cm-71-for-lg-gt540-new-method/
tutorial. Now I want to mention ignore step 9 because you obviously can't boot. Now other thing to boot into fastboot mode press VOLUME UP + SEARCH button and plug the USB cable into the PC. If that don't works press VOLUME UP + SEARCH + POWER ON and wait until FastBoot Mode is shown on the screen of the phone or nothing is shown on the screen (don't worry if you see nothing you're probably in fast boot mode). Then proceed with the rest of the tutorial.
2. Now if you have your phone up and working and want to upgrade to ice sandwich follow this
Code:
androidforums.com/lg-optimus-gt540/494941-update-4-0-lg-gt-540-a.html
tutorial Section 2.
I was messing around all day to workaround this problem and the conclusion is that: this is the ONLY way it worked. I tried all possible ways to flash to stock rom but still stuck on the boot logo.
Hope that I helped someone with the same problem.
Regards.

Cool it works like a charm. I found this .zip with European Open V20A + fastboot.
Btw, do you know what combination of keys would put me in CWM (when starting the phone) or how to get "POWER button until it appears to turn off the menu, select REBOOT and then select RECOVERY, the phone will reboot into Recovery Menu." ?
I tried pressing Power Off+Home or only Home on LG logo but still nothing, it just went into safe mode.
Thanks a lot for the help.

LG G2 F320L stuck in Boot Loop not going in download mode

hi guys,
i flashed recovery using the manual method from this thread http://forum.xda-developers.com/showthread.php?t=2468858.
I wasn't able to use the last command
Code:
rm /sdcard/g2_security
I thought it didn't work , i also updated the my phone software.
When my phone restarted it went to cwm and now its stuck there.
Now when I try to boot I can either get in CWM or some Korean Recovery Menu with three option (i tried all nothing happend) or just stuck in boot loop!
I can't get in download mode by pressing vol up and plugging usb cable (tried all possible methods)
I will be glad if someone can help me out.
Thanks in advance

That's an unexpected situation to say the least.
So in short: installation of recovery worked, but you lost access to your ROM.
Correct?
Now, if you had a flashable ROM on your sd card you would be sorted, no?
I would say, get any compatible ROM, put them on a micro sd card and plug them into your phone. Flash through cwm...
Am I misunderstanding?
Otherwise there is always the fully back to stock option:

I was able to fix my phone using this thread. I was able to get in recovery but not in download mode. After executing these commands I flashed stock firmware through LG flashing tools.

Stuck in recovery mode? Please help !!

Hi,
I was on stock bootloader and stock OTA 4.03 ICS rom. I wanted to upgrade to jellybean rom from tegraowners. I am now stuck in recovery mode.
Here are the steps i did.
1) rooted my A500 succesfully
2) With the Blackthunder APX flash tool i flashed in auto mode the Skrilax_CZ V8 bootloader (with multiboot) also succesfully.
3) Then i flashed with ADB.exe the 1.8.1 Touch recovery image that also went well and succesfully flashed it.
4) Booted in recovery mode and wiped data.
5) Went to install from external zip the latest jellybean rom from tegraowners wich is ofcourse on my sd card.
6) It started to formatting my system partition ( i think it was on 7%) and then it suddenly restarts my tab.
Now the only thing i have is power + -VOL is my recover mode and power + +VOL is my other menu i have wich contain the fastboot menu.
From there i am stuck and don't know what else i can do.
I do have my UID number and SBK.
Here is a screenshot of what i have in recovery mode:
Thanks and hopefully someone can help!

You will have to do a "real" data format. And for more help with ROMs from "other" forums you should ask on those "other" forums.
You will find the moderators here do not condone those "other" ROMs.

Perform a real format, then flash a ROM again (you'd better go to Tegraowners.com for more support), but if the problem persists then it may be a bad download, which means you have to download and flash your recovery again. However at TegraOwners you can also find the latest TWRP recovery.

Cant boot into download mode (recovery/rom are ok)

Hi guys! From what I understand the phone has 3 modes of boot. Recovery , normal and download mode.
I installed TWRP as recovery . At some point the cellphone only boot to recovery (in all modes) , I fixed it with some adb commands but now I got recovery and normal mode.... My cellphone is fine but Im not able toi install any original rom with the lg tools.
I already tested the key combinations and with apks that have the option to boot to download mode presing a button. Booting to download mode enter TRWP
My device is a d806 AND im on rooted stock 4.4.2.
Any idea how to fix this?
Thanks

Any help ? nobody knows how to restore download mode? :/

Stuck in a boot loop and can't access recovery mode

So I flashed a custom rom and it required a specific TWRP recovery. But after installing the custom rom I had to install another TWRP recovery otherwise it wouldn't boot into OS (this recovery was probably unsupported and thus my phone was forced to boot into OS)
So every time I wanted to boot into recovery mode I had to use an app like flashify and flash the first recovery to boot into recovery mode. And after finishing I had to flash the "unsupported" recovery again in order to boot into OS.
Now with the "unsupported" recovery, I installed Xposed and some modules and then restarted the device. And..........boom! The phone is stuck in a boot loop! And I can't even boot into recovery mode.
Now here's the other nightmares I'm getting:
1. Cant use ADB to flash a new recovery because my device is "unauthorized" and in order to fix that I need to go to developers option which is not possible (because of boot loop)
2. Uninstall Xposed: button combinations aren't working and I cant go to recovery mode to flash the uninstaller zip
3. vol up + vol down + power button doesn't open recovery because the recovery is "unsupported"
4. Can't even boot to fastboot mode by holding vol down + power. It tries to boot into OS and starts boot looping
5. Can't use sp flash tool to flash stock rom or recovery because whenever I connect the phone to PC, the phone tries to boot into OS and....you guessed it starts boot looping.
Now I'm out of ideas and really depressed. If anyone can help me out with this I'll be grateful forever.
My device is: Lenovo k4 note
Chipset: MediaTek MT6753
Currently on this recovery: https://androidfilehost.com/?fid=673368273298981920
Got this recovery from here (recovery2): https://forum.xda-developers.com/k4-note/development/unofficial-resurrection-remix-5-8-2-t3570195
Thanks!

Update: The problem is solved after flashing stock rom via sp flash tool

I think the pc cant dtect my device same problem bro after installing new rom it keeps on rebooting after the lenovo logo. Cant also access the recovery mode. Please help me

Bro I'm not an expert. Someone from XDA discord server helped me with this. And I actually forgot the exact thing I did to be honest. I downloaded the sp flash tool on pc and downloaded the stock rom. Then flashed it to the phone. You have to connect your device via USB before. For a detailed guide you can search on YouTube with something like "how to flash stock rom via sp flash tool"
Or ask in the discord server. They will surely help you.

How did you flash that? Can you please explain step by step

You can download the stock rom from here. And there is also a tutorial on how to flash it. I followed it. Hope that helps!

Thanks, the problem is my phone is struck on the Lenovo logo, it's not turning off but my computer deducted it as Lenovo device

If ADB can detect your device then you can just flash a new recovery and you should be fine. But as I said I'm not an expert so I'd suggest you to ask for help on the XDA discord server. That's where I got help from.

Did anyone found the solution?
Thanks

Can any one find the solution of that problem , because my lenovo k4 note also stuck on boot looping logo... and vibrate like bootup time
