I am stuck at Step 9 getting the phone into EDL mode. The phone is LG K40 LM-X420AS. I power it off, hold volume - button, plug-in the cable and nothing happens. Phone starts charging and does not enter into EDL mode. I am able to get into Firmware download mode (Volume + and cable) and also can get into "Factory data reset" mode (Volume - and Power, and then release and hold Power on vibrate). MediaTek USB device does not show up in libusb device selection window.

If you can fash in download mode, you don't need to bypass EDL auth.

I can enter into "Firmware Update" mode, but I cannot flash anything. If I run bypass.bat or main.py I get "Waiting for device". In the device manager it shows as LGE Mobile USB Serial Port (COM6). What tool do I use to communicate over this port? Also, where do I get a firmware I could flash? Thanks.

You need to find the right sequence of keys to enter in EDL mode.
I have no ideia about where get a firmware to a LG device.

Android 10 LK images does NOT work on Android 11.
You need to use the respective LK.
I suggest you to keep the same lk image of the rom you are using.
If you have problems with any recovery project, just use another:

Bypassing auth does not delete data.
You need to format or erase data to delete everything.

Hello
this was clear to me, my question was related to SP Flash tool. how can I flash the ROM without losing my data (photo)? in the procedure described it is not indicated whether it is destructive or not. many users are happy with the procedure but it is unclear if they only recovered the phone or even the data. I want to recover the data, not recover the phone, so I can also do others instead of flashing the ROM. It seems to me that TWRP is perhaps the best way. I am currently unable to install TWRP with SP Flash tool. I managed to do the memory dump thanks to the procedure of unlook and SP Flash tool but the extracted partitions do not contain personal files, only the system files are present and readable, probably because personal files are encrypted, I think I need, and I believe TWRP does it, to decrypt them by entering the phone unlock code, do you agree?

This thread is not about sp flash tool.
Try google or youtube.
Good luck

Hi there all, i know maybe i am in the wrong room, but if anyone has the solution to my problem please give me some enlightenment, coz i have been searching for almost 2 months and still can unbrick my DEAD boot REDMI 9A DANDELION.

This situation appeared after i have already install twrp and also already flash rom and suddenly its went completely dark. I already have tried so many kinds of method or ways i found but always hit a dead end.

And 1 more problem, my 9A only can be read by PC if I bypass the EDL using TEST POINT from my hardware, and i have tried many kinds of flashing tools and also downloaded a bunch or ROMs based on guides i read from forum here and there.

Please if you have the solution for my problem, it will means a lot to me.



Thx before.

You just need to flash the full MIUI again.
Bypassh EDL auth first and then flash it using sp flash tool in firmware upgrade mode.
It will erase userdata and relock bootloader.
Good luck

Done that before, and already most off all the globa MIUI 12 (latest i tried 12.0.16 for dandelion), and the result is sill the same, stuck at DA 100, then Error : STATUS_EXT_EXCEPTION (0x0050005). also tried diffrent DA FILE still ERROR.

Its been 2 months now lol, and when it's near weekend that's all i've tried to solve, my 2 Dead Brick 9A o_Oo_O

Here is the ss of the error and the By pass tool that i used

For the scatter file, i already used form the thread you post

    Hello bro, today I was able to recover my Redmi 9 with the update of the tool that you shared, it was a bit complicated but in the end if it recovered, now, I have a problem, this Redmi is dual SIM and the two IMEIs appear unknown to me and a Wi-Fi network called NVram warning: Err = 0x10 appears, is there any solution to this error?
