I think this is the point where you contact LG support to see if they are willing to help you

unlock bootloader and lg ...out of warranty. You must pay to me do.!

i need help pls..!!

download mode is disabled by kill switch.......is macfee??????

i don't think is mcafee related stuff, it's just an application, kill switch is something that google introduced in android 5.1, but in theory only the owner with the default google account is the only one authorized to disable the kill switch, this method was implemented as a measure against theft

Help [hardbricked device] urgent need of help asap

Ok so i was just rooting when my phone decides to die during so commands in adb. :crying:
Now i cant turn on the phone or boot into fastboot or bootloader. everytime i plug it in the charging light just flashes. Also my computer recognises the device as qualcomm hs-usb qdloader 9008 . ive read around the internet and ive found two methods. blank flash and qfil. issue is those tutorials were made for the moto g5 plus. I have searched around the internet and im beginnign to lose hope now. Can someone tell me how to fix this or give me the right blankflash version.
much appreciated

Im sorry that i cant post a useful reply for your problem that you cant even boot into fastboot / hardbricked phone.
The following link is for all those that are stuck in fastboot mode / boot loop.
This post says its for indian version, but i have EU version (1676) and it worked for me to get back my phone as it was when bought:

if you cant access bootloader take it to a repair shop - you need specialist software and hardware to re-image your phone
how on earth did you do that - you do know to root this device its just a simple zip flashing in recovery mode - no fancy commands or anything required once you have unlocked the bootloader via the very easy to follow guide on the moto unlock bootloader website

If you are using LineageOS all you had to do was just go into dev settings switch root to disable & restart the phone
If you used magisk just use the magisk uninstaller then reflash the kernel
I don't understand why you touched the bootloader partition

I dunno y either. Luckily I had insurance on it so now I got a new device

Although even though I'm sorted it think we need a way to fix hardbricked devices because the Moto g5plus and g4s have fixes but I haven't found any that work for Cedric devices

hey, did you fix your device ?? i got the same problem as yours

Is it even possible to unbrick a locked bootloader Redmi note 5 pro in 2020?

i have literally searched everywhere and tried the methods but to no avail. There are some old methods but they dont work anymore.
i cant access recovery but i can access fastboot but since my bootloader is locked, i guess thats no use.
1. Official flash wont work because not a authorised mi account (if someone have this, please for love of god help a brother out).
2.Tried the famous anti test https://www.youtube.com/watch?v=Pf_pPCGkldI&app=desktop but stuck at "ACK count dont match" and i guess others have this issue too. Do anyone know what this error mean in first place?
service center guys is waiting to rip off money with new motherboard but there must be someone somewhere who have good knowledge about and tweak something to make it work.
tl;dr: please provide a working unbricking method for RN5pro (working in 2020)

Hey bro as u can access fastboot mode, can u unlock ur bootloader via unlock tool?

No, you cant do that. You need to set in developler settings first but since the phone is stuck, you can't do it which means you can't unlock bootloader now using miunlock. if this was possible, we wont be whacking brains in edl n stuffs.
source: i have tried it already n didnt work.

No no, if you get ack error you just need to power cycle the phone (hold power button for 20-30 sec).
Really easy just need to be patient and retry.
Trust me I done it last week on my friends phone.
Just don't give up.. take a break and try it again. I done it in 3rd try. And use patched firehouse file on original MIUI fastboot rom.
Good luck!

I don't know if this help, I unlocked many Xiaomi devices and it usually takes a lot of wait time but I bought a RN5 Pro from second hand and when I tried to unlock it through Mi-Unlock Tool it did it instantly so it looks like Xiaomi don't care anymore for bothering on old devices, just in case you didn't try it previously.
Also it may help some screenshot as possible of your issue from the Mi Flash tool, I always used the Mi Flash tool Pro for unbrick purposes https://xiaomifirmware.com/downloads/miflashpro/ Have present that a device in this state is highly unresponsive so you have to try it a lot of times to get it working again changing always some things around.

Unlocked a Note 3 bricked like that back in the day using the EDL mode with MiFlash. Just a tip, don't know whether that'll work here.
Another tip: Don't buy any more Xiaomi devices.

Yeahh Xiaomi's edl authentication is bull****.
Locked edl flashing (which they thought was a security measure) but they bundle miui with full of crap and data miners.

Yes I tried everything even miflash pro and miflash 2018, miflash 2017 and flashing old rom both global or china mode with or without the new ssd660.elf files or patchprogram etc. I tried with connected battery and no battery in EDL mode and nothing is working just error of ACK COUNT COULDN'T MATCH cannot flash anything even with QFIL di qualcomm such a shame for Xiaomi! I think EMMC is corrupted then. Can't think of any other reason!
How did you solve the issue now in 2021?
What did you do?
Was the phone only able to go to fastboot and edl mode or also recovery? Cause mine only MI LOGO, fastboot and EDL mode with locked bootloader and EDL mode only via test point with open back cover!
Thanks

ACK COUNT COULDN'T MATCH this warning is linked to a synchronization attempt between programming Computer and interface controller the data transfer rate needs to be HIGHER than normal USB serial link transfer rate it seems.

the bootloader needs to be unlocked first remember the WHYRED is an android device all android devices are based on linux kernel the flashing computer OS must have a core ADB support and linux terminal and a linux kernel to complete the job

I need help i tried flashing fastboot ROM with MIUI tool and now its stuck in bootloop also cant access bootloader

Question hard/soft bricked

I tried downgrading my Moto G30 from Android 12 to Android 11 using an available stock ROM I found on the internet. At first, I faced some problems and a soft brick, but finally, I was able to flash and boot it correctly. Then, knowing that the ROM flashed was "stock," I decided to relock the bootloader, which was a mistake. After rebooting, I got the message "No valid operating system could be found. The device will not boot."
I spent the whole day trying to figure out how to get it working again. The main problem here is that I relocked the bootloader and can't get to the OS again to enable the option in developer settings to re-unlock it and flash another ROM. I tried using RSA (LMSA) to restore it, but it refuses, and I think it gets the same error that won't let me flash anything to the phone.
During my research, I found that one possible solution is to boot in EDL mode and flash everything again, but I don't want to open my phone and do weird things to get into that mode. Hopefully, there's another solution or another way to get into EDL.
If you have any information that could help me solve this, please comment.

I had the same problem with mine. The thing is, i tried to flash a blank-flash image but it wont go. I think its to early to downgrade your Moto G30, but you can try to flash the stock image in EDL Mode by opening your Motorola. Also you might need to send it to Motorola. Sorry
In the image you have the EDL Test Point you must brick.

But also you can try

Don't you need to just blankflash it in EDL?
And yes you most likely need to open it.
For the Blankflash you need to download Lenovo Rescue and Smart Assistant (since lenovo produces moto phones). What this does it installs the correct drivers for your phone.
And the files can be found here : https://mirrors.lolinet.com/firmware/motorola/caprip/blankflash/
Good luck and as always, do your own research!

I think you can flash with Lenovo Rescue and Smart Assistant or manually, the XML is to flash automatically, you can flash manually each image.
If you cant maybe there is an error along the way.
I might look into this later. I would lock my bootloader to test but i dont have a backup.

I dont have a test device right now so i cant test myself, anything I say might be wrong.
This might be a complete brick because of the downgrade from what I've read.
There is little info on the forum about this issue so I don't want to make wrong suggestions until i can test.

Yes, unfortunately, there is still little information about the Moto G30. But I hope that there will be more information and solutions in the future.

Maybe you can help me with some info i am interested in.
1.You have booted into EDL using Short Pin method
2.You have used blankflash successfully
3.Then you try to flash manually and got Permission Denied?
For both Android 11 Stock ROM and Android 12 Stock Rom?
EDIT: Is the back of the phone glued? Or just clamps so you can put it back with no glue?
Since i want to test this soon hopefully.

1. Yes
2. I used a blankflash successfully.
3. Then in fastboot tried to flash the android 11 stock and after it failed the android 12 stock image. Also i tried the RSA varient. Both will not work.
The back is clicked in place. There are two stickers on the phone. Two white ones, One on the top left corner and one on the bottom of the phone.
But careful when you open the back. The screws are well screwed and the cap over the motherboard is slightly stuck. Maybe this will help you: Dissasembly Moto G30 YouTube

@U_ShowcaseDev Thank you so much! This is exactly what i wanted to know!
