I tried to downgrade LG P500 from 2.2.1 to 2.2 by following these steps.
Install msxml.msi from the uncompressed directory
Conect your device (do not turn on disk storage) and run KDZ_FW_UPD.exe (Has administrator).
Select Type : 3GQCT
Select PhoneMode : DIAG
In KDZ file : Choose the ROM file you downloaded (V10G_00.kdz file)
Press Launch software update and wait (It will be 10 minutes or so). In your phone it will appear "Emergency mode". Wait until it reboots.
The phone never rebooted. When I manually try to reboot, it comes to Android screen and never gets past it. Has anyone faced this issue?
Thanks.

this method only works if you have USB debugging enabled on your phone, right?
For that you have
1. Internet enbled pc
2. SMG360H mobile with Samsung USB driver
3. An USB cable
Methods:
#1st: Download kingoroot for windows pc from below my post.
#2nd: Plugin your device using cable and join with pc.
#3rd: Enable usb debugging mode. For that go to Settings then press 7 to 8 times on 'Build Number' browsing 'About Device'
#4th: Power off the device and bring your phone to download mode. For that press simultaneously volume down, power and menu button. Then press volume up button to enter download mode
#5th: Hit root button on kingoroon on pc and wait (Time depends on network speed)

Lets Begin
Flashing Guide
WARNING: Everything apart from data in external SD card will be wiped. Make sure to backup everything.
1.Download the QFIL flash package ZIP and appropriate ZIP from Drivers+QFIL.
2.Extract the ZIPs to a folder whose complete path has no spaces (space characters) at all.
3.Make sure you uninstall any other phone's PC Suite/drivers as they may cause conflicts. Microsoft Emergency Driver (installed for restoring Lumia devices) is known to conflict, please uninstall it.
4.Go to Drivers+QFIL folder extracted in Step 2, run the appropriate 'INSTALL_DRIVERS_&_QFIL.bat' and follow the instructions.
5.Backup contacts, SMS, apps, etc. as well as the entire internal storage as they will all be wiped(you will setup a new phone). Internal storage WILL BE erased when using the QFIL flash method.
6.Run 'QFIL' program. (If Unable To Find It Search It In Start Menu You Will Find It There)
7.Select 'Flat Build' as build type.
8.Click on 'Browse', select the 'prog_emmc_firehose_8992.mbn' file from the 'X3a40_S217_160623_ROW_QFIL' folder which you extracted.
9.Click on 'Load XML' and select 'rawprogram0.xml' followed by 'patch0.xml'.
10.Make sure you completed each step precisely, the USB cable is connected ONLY to USB port (USB 2.0 preferably) of PC and not to device yet, the device is powered off and is charged (at least 40%).
11.Now boot into EDL by plugging in the USB cable to device and quickly pressing and holding power button for ~1 second. QFIL's 'No port available' text should change to 'Qualcomm HS-USB QDLoader 9008 (COMXX)'. The display will stay off so, don't worry about it.
12.Within ~5 seconds put the device on a stable surface (so that it doesn't move around or shake) and press the 'Download' button on QFIL. If you are late, the device starts to power on normally and you need to go back to Step 11 and continue.
13.Wait for the flash to complete and 'Download Succeeded' message appear at the bottom.
14.Unplug the USB cable from the device and press and hold the power button for ~10 seconds to power it off.
15.Now power on the device normally. If display doesn't turn on press and hold the power button again for longer time, it will boot.
16.Once you have finished the initial set up, open dialer, dial '####682#', choose your region (IN - For India) and confirm. [Don't Skip This Step Its Important]
NOTE - IF Having Trouble In Installing The Drivers Or Detecting The Phone In QFIL Google On How To Disable Signature Enforcement In Windows 8 or 8.1 or 10 And After Doing That Again Install The Drivers.

TIPS & INFORMATIONThe various modes X3a40 can boot into:
Recovery mode: Press and hold Volume up + Volume down + Power together until Lenovo logo shows up and flickers once. Release the buttons and you will reach the recovery. This opens up the recovery of the device.
Qualcomm Diagnostics mode: Press and hold Volume down + Power button together until Lenovo logo shows up and flickers once to boot into this mode. This opens up the Qualcomm Diagnostics screen which has a number of hardware testing and other tools along with ability to flash the stock ROM. It is also used for further Diagnosis using a PC.
Fastboot mode: Press and hold Volume up + Volume down and plug in the USB cable(already connected to PC). You may also use the ADB command "adb reboot bootloader". Obviously you need a working device with USB Debugging turned on and ADB installed on PC. This opens the traditional Fastboot interface.
EDL mode: Plug the USB cable and quickly press and hold the power button for a little while. Device stays in EDL only for ~5 seconds unless you start firmware flash via QFIL. You can also use ADB command "adb reboot edl". This will put your device in Qualcomm Emergency Download Mode which is meant to flash stock firmware using QFIL tool on working/bricked devices.
Normal mode: This is what you boot by normally pressing the power button. I don't need to say much about this one.
Keep your NV data (IMEI, Serial No., etc.) backed up from QFIL>Tools>QCN Backup Restore. Device must be in Qualcomm Diagnostics mode. There are many more ways to do this.

Will just flashing the SuperSU zip enable me to get root in Marshmallow rom?
Or should I do everything from this thread again to gain root? I already have root in my lollipop and want to update to Marshmallow only if I can get root in it.

Hello, y'all,
... First of all, please read this whole post carefully, before starting to work on your phone! Thanks! ...
recently, I wanted to update the Android version of my old Z500 with the help of lineageOS and TWRP.
Please note, that I'm not at all an expert on this topic, and if I'm using specific terms like "bricked" or "APX mode" wrong, please forgive me.
So, on my device, I had the plan of installing Android 6.0 on this phone using TWRP and a copy of lineageOS.
However, the recovery partition turned out locked and I accidentally overwrote the boot partition with the twrp.img.
This is my first time doing this, ok, and I read on a oneplus forum, that the boot partition could also be used, blah, blah, blah, silly me.
Anyways, now my device wouldn't turn on. After a while charging, the display turned on, but there was always just the low battery screen. When I got to the "Boot Selector" holding the power and vol + button, selecting fastboot, recovery or normal boot just restarted the device.
Anyways, now what do you need to "unbrick" the device :
- A version of TWRP [dl.twrp.me/Z500/twrp-3.3.1-0-Z500.img.html]
- A version of your desired ROM, for me lineageOS [androidfilehost.com/?fid=889764386195903470]
- SmartPhone Flash Tool, for me v5.1912 worked like a charm [spflashtool.com/download/SP_Flash_Tool_v5.1912_Win.zip]
- A copy of the Firmware Acer_AV0K0_Z500_1.012.00_EMEA_GEN1 (... GEN1s for single SIM) [dl.dropboxusercontent.com/s/cin08ytkqmvr7c1/Acer_AV0K0_Z500_1.012.00_EMEA_GEN1.zip] (this was the hardest one to get because all the other downloads just included the .ispff dump file)
- A copy of the corresponding version of OpenGApps [opengapps.com]
- A copy of the MediaTek Driver Auto Installer (v5.1632.00; you know you have the right one when it resets the USB Ports in a CMD window at the end; INSTALL THIS FIRST) [mediafire.com/file/4ux1ytmzlxmpbjb/ROMProvider.COM_Driver_Auto_Installer_EXE_v5.1632.00.zip/file]
- A USB Charging Cable
- A PC
- Your Phone, obviously
Set up your PC :
1. Start by installing the MediaTek Driver Auto Installer. After that is finished, restart your PC.
2. Unzip the Firmware and the SmartPhone Flash Tool
3. Copy your ROM and OpenGApps on an SD Card.
Before you begin this operation, make sure you "get your device into APX mode".
Basically, it makes your device recognizable and flashable by the computer.
WARNING: DO THIS AT YOUR OWN RISK.
To do that follow these steps one after another :
- Plug your device into your wall power, NOT YOUR PC, and let it charge for about 30min, just in case. Turn it off if it's still on, although in my case, it turned off once I removed the charging cable.
- Remove the backplate of your device, unscrew the internal backplates 6 screws and carefully take the internal backplate off. If you're having trouble, just look for "Acer Z500 teardown" on YouTube.
- Carefully pull off the battery connector from the mainboard from up under. Be careful not to damage it!
- Once done, connect your device to your computer. You should now see the device as COM Connector in the Device Manager. If your device is disconnecting and connecting repeatedly, the driver must not be active. If you see no device connecting at all, remove it from your computer and after plugging it into the wall charger again, reconnect it to your PC.
- Once that's ok, disconnect the device again, and plug the battery back in.
- While disconnected, open up the SP Flash Tool, and under "Download", select the scatter .... .txt file from the Firmware Archive.
- Once that's done, all of the checkboxes in the ROM select should be active.
- Double Click on the Path of the "RECOVERY" row and select the TWRP.img. Then, change the mode from "Download only" to "Format All + Download" and hit the "Download" button.
- Plug your Z500 back in again, and you should see the flashing process starting.
- Once that's done, disconnect the phone and put the SD card with your ROM and OpenGApps in.
- Connect your phone to the wall charger again, and immediately hold the power and the vol + buttons down, till the Boot Options appear.
- Boot into recovery mode, and TWRP should start up. If it doesn't, reconnect your phone again and just let it boot for around 3min after terminating it by holding the power button and as soon as the screen goes black, also holding the vol + button. Once again select recovery mode, and now TWRP should defiantly show up.
- In TWRP, first, make a factory reset with the "WIPE" option. Then go to install and choose your SD card. First, install your ROM, then OpenGApps and reboot.
Now you should have a functioning Acer Z500 again!
Feel free to reply, if you have any questions!
Good luck,
Klydra.
