how can i back in normal 2.1?

Downgrade from 2.2.1 (2.3) to 2.1
1. We go in and write FastBoot:
- Fastboot.exe-w (This command does XP)
- Fastboot.exe erase system (cleaning section System)
- Fastboot.exe erase boot (clean partition boot)
- Fastboot.exe-w (To be sure)
2. Flash a rom with kdz updater
got it from 4pda, it should work.
It will not work: many have problems after first time use fastboot roms. It looks like that only small percent of owners can flash GT540 with stock ROM and in that case phone work. Many can flash but phone stuck at boot logo. If you use fastboot 2.1 it will work normally
^^
so i cant downgrade my phone with ROM that have no fastboot?
Try, you cannot loose anything. Maybee you will be in that few pwercent of users that downgrade works.
Just use a fastboot rom, I sold my silver GT540 with a fastboot rom on it then got a White one, to be honest, Most phones from other manufacturers have fastboot enabled anyway, so I don't see it as a problem

Well i'd recommend using your backup you made using clockwork recovery
I hope you made one
ohh u m not take backup of orignal 2.1..
have any one backup
plz give me link of bakup 2.1

It does not cause a problem to downgrade to 2.1 without fastboot, I have done that several times. All you have to focus on is the following:
after doing "fastboot -w" turn the phone off. And DO NOT TURN IT ON AGAIN. Remove the battery, sim and SD. Hold the camera + power and then plug the phone to usb it will run into download mode. Run the KDZ updater with CS Emergency mode and flash whatever 20A rom you can have. Before the update ends, it will reboot and ask you to insert the battery. Do not unplug the phone until the KDZ updater gives you the ======= finished ====== message.
I hope this helps.
first, try restore with clockworkmod the backup of the 2.1 rom and after flash the original rom with kdz
guide here
i have followed all the steps but when i connect phone to the computer and try to run the kdz updater i get phone not found and ideas whats wrong
The king
You are the man, thank you sooooooo much, two weeks on getting the downgrade working and this works a treat.
After downgrade I was able to get into the unlock menu and was able to enter the unlock code, I am so happy for your post.

yeah just turn your phone off and plug in your usb, hold camera and power for a bit and it should connect. It may still be black screen but do not worry, then run kdz. I can tell when it connects by have my computer open on windows 7 and you will see it flash up on the left hand side. Other times I hold power and home key? The trouble I had was just horrible but just be patient.

Hi
I am new to andriod devices, once i bought this LG L5 612 device i wanted to unlock it to all networks, so went searching the google and found some =videos which stated that you need to root your device first to unlock your phone for any network, i did root my device, but learnt that you need to do more than that to unlock your device for other networks.
After that i did kdz updater and that was my current state of my phone,
Yesterday i had an information on my phone which stated that , There is a software update available for your phone. I did install that which asked for a restart , and after that restart my device starts flickers a second and goes directly to CWM recovery, I dont know what to do next , i dont seem to have any backups and stuff.
Could anybody who knows how to get me out of this , can you please lend me a hand,
Hi, mmm you cant unlock the network without pay for the code, in others android like galaxy ace there a root app but not for the l5.
Reinstal a kdz with kdz updater in emergency mode

How to instal LG Firmware using KDZ Updater
1. Download and Install USB driver for Lg L3 e400 from LG website or here
2.Download and install MSXML 4.0 SP3. here.
3.Download KDZ Updater here then extract it to your computer.
4. Download KDZ file according to your country or any compatible KDZ file. Download here
How to use KDZ:
1. Detach your external SD from your phone.
2. Remove your phone battery and wait for a few seconds.
3. Put your battery back to the phone.
4. Press volume - and + (or just in the middle of volume button) and power button at the same time.
5. wait till the phone screen turns to yellow (emergency mode) then release all the buttons.
6. Connect your phone to PC by using USB cable (your LG cable).
7. Stop or disable your antivirus or antimalware.
8. Run KDZ Updater as administrator.
9. Choose the following options in KDZ Updater:
Type: 3GQCT

and browse KDZ file is the one you downloaded, browse where you put this file and then select.

I have 4.0.4 ICS (cm9) on my LG L3 (e400), I tried to flash to stock since official 4.4 (kitkat) is coming soon but it does nothing, just reboots normally after flashing (no errors reported with kdz flasher) with my wallpaper and everything, and it says that my battery is charging but it's not connected to charger or computer. Any ideas?
I did everything from the guide, step by step, and I'm stuck on this error: Upgrade Error: Wparam: 100 LParam :1010
I especially looked ower firmware, and I'm positive that I downloaded the right one.
I tried several times, and every time I get this error. Also, phone now boots to Emergency mode, and can't boot to something else.
Don't know what to do? Anyone help?
Just reinstall driver, reboot pc after instalation and run kdz as admin.

You can only enter emergency mode because you haven't finished installing_KDZ. If I were you I would try download and install another KDZ file.
It will only work when you get the right KDZ file for your device. Don't worry to try another KDZ file.
Try another KDZ updater,
Unable antivirus and firewall.
Keep on trying. I hope these will unbricked your phone.

I can't turn it off completely without removing the battery. When I place back the battery it turns on immediately, so I don't have time to hold button combo..... :/
Download Quick Boot Reboot from play store. Run it select recovery then it should hard reset your device.

After removing battery wait about 15 seconds and put it back. If it still fails, remove battery and wait for longer time.
Just keep on trying.

Have you tried entering into CWM?
If so, then you should do factory reset, wipe cache, and go to advance then wipe dalvik cache then restart your phone.

Tried that, tried flashing another roms, tried KDZ, tried multiple stock roms....nothing works.... It says it's charging without cable being connected.
stuck with cm9
For those you stuck and cannot flash back to stock ROM. enter to CWM, and leave it there. Connect to PC and flash with EMERGENCY mode (not DIAG)
Works perfectly, tested in Windows 8
Thanks!

What am I missing?

After you unbrick your device with EDL with patched programmer, you might have issues with your partition table being problematic and TWRP not flashing ROMs that are zipped.
This may also happen when MIUI gets updated to a degree that it doesn't accept custom ROMs.
Here is the solution.
Prerequisties
Download MIUI Fastboot ROM version 8.9.6
Download MiFlash 2016.04.01.0 (64 Bit)
Download TWRP CN
Download the patched programmer
Installation
Way 1 (Fastboot way)
After you have done downloading the needed files, install MiFlash, extract the firmware.
Open MiFlash, select the firmware folder, choose Flash All.
Boot to fastboot
Click refresh after you have connected, and flash.
After done, instantly boot to fastboot.
Boot this TWRP: recovery-TWRP-3.2.3-0810-XIAOMI6X-CN-wzsx150.img
Backup your whole phone (excluding "System Image" and "Vendor Image") just in case and copy the backup to your computer.
Flash a ROM now.
Format data.
Flash the ROM again.
Way 2 (EDL way)
After you have done downloading the needed files, install MiFlash, extract the firmware.
Then, backup stock "prog_emmc_firehose_Sdm660_ddr.elf" somewhere else, and ONLY REPLACE THAT FILE WITH THE PATCHED ONE.
Open MiFlash, select the firmware folder, choose Flash All.
Force your phone to EDL. If you can flash via normal ways, good for you. But if you can't, there is only one solution. Testpoints. (Explained later)
Click refresh after you have connected, and flash.
After done, instantly boot to fastboot.
Boot this TWRP: recovery-TWRP-3.2.3-0810-XIAOMI6X-CN-wzsx150.img
Backup your whole phone (excluding "System Image" and "Vendor Image") just in case and copy the backup to your computer.
Flash a ROM now.
Format data.
Flash the ROM again.
I don't recommend flashing TWRP. Boot if you need.
How to testpoint
• Turn off the phone, unplug the USB.
• Unscrew the bottom screws.
• Open the back of your phone, carefully. You may damage your screen.
• Unscrew the port protector.
• Unplug the screen, battery and EDL protector.
• Connect two EDL Testpoints with a metal piece and connect the device to the PC via USB.

Hi, i Hope you Can help me.
Some months ago i rooted my Mi A2, After some weeks i wanted to go back to stock, and i tried to do It, but i missed something and the process went wrong. I tried to Save It with EDL, the first flash was good and phone booted up, so i decided to turn It Off to reassamble It, but After that the phone didn't boot up never again, i tried some others flash with edl, mi flash said success but the phone didn't boot.
I tried several times but in the last (i think) 50 try mi flash returned errors like "cannot read from port... etc", After this several tries my phone stopped to go to edl, (connecting test points doesn't work) and now It is completly dead. I tried to let It discharge and take It in charge for some days, nothing works.
Do you have any idea?
Thanks.

Use QFIL instead of MiFlash and disconnect the battery. Hold testpoints and connect the phone to computer.
Make sure to plug out the correct one (the one with black overlay, not the right, wider one. That's of USB ports).

you have the same problem that i have. your phone can't go to fastboot,recovery,boot,no vibration,no LED blinking. only 1 thing works that is stucks in EDL Mode.
did you have this same problem ?
If yes, then your eMMC is corrupted !!
you need to be go to a talented person that can open your mobile and remove eMMC then put eMMC in UFI Box or EasyJtag Plus Box. then eMMC is programmed from there and after this reentered eMMC in phone !!
and your phone will be Boot Successfully !!
Thanks !! :good::good::good:
