Hey folks,
its bricked due to FOTA (I think it stands for: firmware over the air) update. This means the phone downloads a firmware update without computer connection or further PC-Software. Alas it didn't work.
Situation:
Phone starts, displays LG Logo and after that an 'updating firmware' screen for about 1 sec before rebooting and doing it all over again.
What I tried to solve this:
set up a new Win 7 32 bit machine to try to unbrick it. (drivers didn't work correctly on 64 bit) at least the MCCI driver update didn't)
connected the phone with the PC in Emergency Mode (holding VOL_UP + VOL_DOWN + PWR while USB is connected)
downloaded B2CApp (LGSupport Tool) and installed the device drivers for Emergency mode.
disabled the Android(Modem) dirver
downloaded V10D_00.kdz from LG home page
using the phones IMEI and this link:
http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=IMEI_NUMBER_GOES_HERE
This gave me this link
http://csmgdl.lgmobile.com/swdata/WDLSW/LGE720/ADEUBK/V10d_00/V10D_00.kdz
I'm German so this seems all right, but I'm no expert
installed msxml
ran KDZ_FW_UPD_EN and tried CDMA in CS_EMERGENCY Mode
A bunch of magic happend until the phone restarts during the process and is right back where we started, if I put it back to Emergency Mode while KDZ_FW_UPD_EN is still running the process finishes, but to no avail.
The log of this try is attached.
Where I am stuck now:
phone:
runs in Emergency Mode
is recognized by KDZ_FW_UPD_EN as well es LG Support Tool
Flashing via KDZ_FW_UPD_EN finishes
Flashing yields no result.
What else did I try
download V10C_00.kdz, as well as V10A_00.kdz from LG site and tried those with same result as with V10D_00.kdz
tried 3GQCT Type instead of CDMA
Wild guesses by me:
I need a different KDZ_FW_UPD_EN version, maybe different dll. I got it from here somewhre in a LG P500 related topic.
I messed up the driver install or need a different driver
LG hates me personally and planted this whole brick specifically to get to me.
The device really is permanently bricked, so I did all I could and there is nothing more to do? That would be sad, I hope I'm wrong here.
Additional Info:
The phone is not rooted and has never before been flashed. It ran with the same stock firmware since it was unwrapped.
The phone was not interrupted by power-loss during FOTA update.
The [read phone information] tool from KDZ_FW_UDP_EN crashes every time, maybe this tells somebody where things go wrong
Any help is appreciated. Ask for more info, if you need it.
Update - What else did I try:
I got the LG Support Tool to flash the Emergency Recovery all by itself runs till 99% --> reboots --> still stuck in same ol' bootloop
reentering Emergency Mode from the bootloop makes the Emergency Recovery finish with 100%, no error, but still bricked.

Hello!
I have a bricked phone. When I got him, he was in a state "loaded to the screensaver and stop".
I decided to flash him using recovery (carliv touch recovery 2.2). Thanks to recovery I copied all the files from phone. But all my attempts of flashing were unsuccesful - I've got the errors while recovery did an unzipping.
That because I decided to use SP FlashTool. But I've forever got the same error 5069.
I notice, that I can format my phone and download the preloader. But it's all what I can.
What I tried (what i remember):
to load without and with battery;
to put a battery after beginning of flashing;
to flash with pushed power, volume control buttons - all together and alone
to use another system, cable and computer (2 cables and computers, windows and ubuntu);
to flash different versions (from off site);
to use different versions of sp flashtool
Also I found a video, where propose to do the backup of working phone (prestigio 3400) by MTK droid tool and try to flash this.
I would be very grateful if you help me. Thanks
Hello everyone, a couple of months now are also thanks to you in the world of modding. Yesterday (i have a Xiaomi Mi A2 Lite) during the installation of a custom ROM using ADB, typing in the fastboot command "erase system", I wrote erase a_boot for error because before I was reading a post about it and I wrote it. Yes I know, I was too stupid. Result? The phone does not start up either in recovery or in fastboot mode, and from the PC it is recognized as COM port. I have already documented about it and tried to flash everything with the Qualcomm tool after installing the drivers but nothing. I tried the EDL by activating it manually to unlock port 9008, but still during the flash gives me error. I tried everything, do it all over again in a newly formatted and clean PC from any other driver, but nothing. During the flash, even if I put the firmware in the same directory, it still gives me error. Guys I'm desperate please. I do not know what else to do. I hope to receive your answers :crying::crying::crying:
I also have same problem.. if you find some solution then tell me also.. my device is different.. but problem is same.. device basically dead & can be recognised in com port
This is a last ditch effort to restore your phone to working order. This should only be used if your phone DOES NOT BOOT AT ALL or if you are unable to boot into FASTBOOT.
If you can boot into Fastboot mode then I would encourage you to flash using Mi Flash tool.

Tested! Howto Unbrick Redmi 9C (angelica) without using auth account
This blog has move and will not be update again.For new update please open ▶▶
langithitam.wordpress.com
First you need to extract the MTK bypass tool which is crucial as it will allow us to flash without requiring Auth file. NOTE: you need to disable antivirus or it will delete file.
Your PHONE NEEDS TO BE OFF! There is no need to unplug battery from the phone, I tested it myself and as long as the phone is OFF it'll still work. If your phone cannot power down due to bootloop, then you must remove backcover and unplug battery or just wait till battery runs out.
Once you have started the MTK bypass tool, choose MTK6765 from option that says auto and this is only for Redmi 9C. Now press on the bypass button a ad it will wait for you to connect your phone via USB. DO NOT CONNECT YOUR PHONE PRIOR TO THIS. Hold only the VOLUME UP button when connecting the USB cable to your phone and ensure the phone is OFF. ONCE you connect the phone, it will immediately respond and show a log saying its completed (SEE SCREENSHOT BELOW).
Once this step is completed leave your phone connected as you will soon start the flashing process. Open up SP FLASH TOOLS and run as admin. You will need to load the scatter file which is included in the Fastboot ROM under images folder. Once you have the scatter file loaded, SP tools will proceed to load all image files which will be used to flash phone so be patient.
Ensure that DOWNLOAD ONLY option is chosen as format and download option will format your IMEI also. Once all files have been loaded then just press the DOOWNLOAD button and wait to complete. Once done you can power ON the phone and it should boot.
Very good guide.
Thank you very much
No problem hope it'll help a few guys out there sure helped me a lot
Thanks 100% it worked for me

Cool glad I could help
I'm using a Redmi 9c I tried to unlock it but failed in the process. Later I get absolutely no response from the phone, I cant open fast boot or recovery. I tried connecting it to the pc but it shows the same exact problem you are facing. I tried all USB ports and switched cables back and forth but no success. I tried pressing volume up, down and all sorts of combinations, still no success. Any fix for this?

Follow the guide step by step, it should work and if doesn't then you should try disconnecting the battery
great guide on fixing a hard brick.
My compliments and thank you very much indeed to you for writing this very good and detailed guide. My Redmi 9c bootlooped after trying to install Lineage OS, of course no way to go to fastboot mode anymore (I'm a rather experienced custom ROM installer though). Although I asked for help in a separate thread, I got no answer for a couple of months now until I found this thread. I never gave up my Redmi 9C so I now followed you instructions and with success!! I will refer people to your thread of course. There is no doubt many can save their phone by reading you instructions.

I can do this for a Redmi 9a?
Using the same download agent
Hello, i did it but i did the mistake to do a FORMAT AND DOWNLOAD.
No my phone juste diplsay the Redmi logo a few second then power off.
I'm still able to go on the Sp Flash Tools and flash again. Anyone could help me please ?
hello sir so i recently hard bricked my redmi 9c nfc by installing older MIUI version that it came with. It was just black screen all the time and nothing. Tried this guide, mtk bypass tool worked but on sp flash tools i am greeted with this message.
Everything is acting like expected according to the video, but wheb I have used the mediatek bypass tool with green OK and stuff and when i start to press download on the smart phone flash tool, it just stucks at 0. Nothing happens, except that everything is greyed out and is trying to load it. If i boot my phone myself with the brom it says hint:add a authentication file or ask for help. I cant manage to finish it.
The error in Mediatek bypass tool about handshaking error is probably because i did it several times, because i didnt manage to load smartphone flash tool as attached below
This is my last hope to recover my brandew phone. Thanks for the good tutorial, but it didt work out. If someone could save me then I would be grateful

Install usb dk drivers 32bit or 64bit, install usb win32 tool
Hello,
This problem has been going on for a while, and I just decided to try and tackle it again.
My phone is currently bootlooping.
Realme logo - "Orange state" your device has been unlocked and can't be trusted, it will reboot in 5 seconds.
It then reboots...Nothing.
I know what I need to do, but I can't get Windows to recognize the device. I've tried holding volume + and - at various times when the screen is black. I've tried volume - and power, I've tried vol + and power...Nothing works.
I can't even get it to turn off...No idea how to get Windows to recognize my device - Currently trying to get the Libusb filter wizard to see the phone to installed the drivers...I've also used the mtk thing too - But it never finds my device.
No idea what's going on here...
Searching for some advice in case I'm missing something simple...
If you cant boot into anything you need to unbrick your device.
Follow that guide, helped me many times...i already needed to unbrick that damn thing for about 20 times.
Keep that files on your pc for future needs, its big.

Great, thank you for the tutorial. That one I haven't seen yet.
However, the BIG problem that I have is that I can't connect it to my PC. LIBUSB doesn't see the device, Windows doesn't see the device. and any software doesn't see the device.
My issue comes with holding the buttons to have my phone boot into the specific mode required - I can't get it to boot into anything other than a loop...
