Plz help : Boot loop, recovery gone, no system, no recognization ...

Hello all,
I've got a big problem after resetting my LG G4 to default settings.
But let's start chronologically :
My LG G4 (bootloader unlocked, rooted, TWRP, Freedom Rom V7.5) should have been reset for being used by another person.
I started TWRP, did a factory reset and a full wipe and restarted it.
By then, the phone only started in TWRP... REBOOT SYSTEM also caused a TWRP restart.
I tried to fix this by flashing CWM recovery via adb and then reinstall an image.
Connecting via adb succeeded, flash recovery succeeded .....
But now, there isn't any recovery anymore. Entering recovery by POWER /VOL DOWN causes the
same boot loop as starting the system. The LG logo appears and it restarts immediately.
I only can start in download mode via POWER UP / CONNECT, but the phone isn't recognized in adb
or in odin anymore.
Doing a complete STOCK FLASH via LGUP TOOL can't be done due to the tool telling me that the
model is unknown....
Is there any way to bring the phone back to life again ? I'm totally clueless ... Thanks in advance !

Sorry, I misunderstood your answer ...
Searching for related posts using the keywords 'boot loop' or 'recovery gone' really doesn't help me ...
As I said, I can't use
- Recovery
- adb
- FlashTool
- odin
anymore in any way . All posts I've found suggest things related to them ...
Most bootloop topics recommend using one of them in different ways ...
Is there a tool not mentioned yet that will help me with my problem ?
As I said, thre search function does'nt bring me to a clue

Connect your device to the computer and see how is detected by "Windows Device Manager".
If not as it should, try to uninstall all related hardware drivers, like modem, adb device, whatever...
Reinstall "LGMobileDriver_WHQL_Ver_4.2.0"
Reinstall "LGUSBModemDriver_Eng_WHQL_Ver_4.9.4_All"
Reinstall "Minimal ADB and Fastboot"
Reboot your computer and reconnect yout device. It should work.

What modem and bootloader (is it v29a nougat beta?)
FWUL is good (https://forum.xda-developers.com/an.../live-iso-adb-fastboot-driver-issues-t3526755) as it avoids any driver issues - it is a bootable linux distro with LG tools built in.
In there, SALT can tell you what your bootloader stack is. Let me know as the version depends on the steps you should take next

Good enough for me
Look at the system one - It says v29a.
So what I want you to try now. Power off your phone. Then, hold power and volume up and hopefully it will boot into the bootloader (at which point you can reflash twrp from twrp.me - cwm is completely outdated)

Mine when I connect to PC (USB2), option "Only Charge" on the phone and turn ON, is shown in Device manager as "Android device/ Android Sooner Single ADB Interface"
Also as "Device/G4"
After change the option "Only Charge" to "Multimidia Devica (MTP)", is shown as "Android Device/LGE Mobile ADB Interface".
Also as "Portable Device/G4", and, "Modems/LGE Mobile USB Modem".
In "Firmware Update" mode, comes as "LGE AndroidNet USB Serial Port (COM4)" and also as "Modems/ LGE AndroidNet USB Modem".
If the phone had v29a installed, you need v20p.kdz and respective "8994.dll", you can extract it from the .kdz. Than you can use LGUP.

Strange. Sounds like you may have a mixture of v29 and v20
Try pulling the battery. Then put it back in, hold vol down and plug in the usb cable and keep holding vol down.

Look at the firmware(laf): v20g
That's his bootloader stack
He flashed freedom ROM which has v29a as base that's why system shows v29a.

Do you have the right "8994.dll" ???
Because to get out from v29a you need the v20p.kdz and the ""8994.dll"" from it. Thats probably why your phone is "unknown"

You just need the right "8994.dll" on the folder "C:\Program Files (x86)\LG Electronics\LGUP\model\8994", replace the one that you have there with the one extracted from the v20p.kdz.
After that run LGUP.

Question can't get into edl mode

how can I get oneplus 9 pro into edl mode while it's refusing to turn off?
keep in mind that I can't use adb. but was able get fastboot devices command to work
and I did not use any third party roms, didn't unlock the bootloader, and do not have root.
I just updated to the latest oxygen os 12 c44
I have tried: fastboot edl reboot, fastboot oem edl, fastboot edl-reboot and none of them worked
I need a way to make it go into edl mode
Have to tried with the button combo? if yes what was the result?

the button combo as in vol+ and vol-
yes I did
I tried to force reboot... and as soon as it tries to reboot I hit the button combo
it takes me back to the fastboot
I had the same issue yesterday and this is what worked for me. Takes a few tries. Just be sure all drivers are good. Without being connected to the pc do the button combo, after a second plug it into the pc with MSM open whilst continuing the button combo. The screen will give a quick flicker of black/green and It will eventually connect to the MSM tool.

Make sure you have the proper driver installed. And try using a different cable that the C cable that came with OP9 Pro.... If you are sure the driver is installed, do the following.
1. Open MSM tool and select required options.
2. Make sure he mobile is switched off.
3. Connect the USB cable to the computer and then connect the other end to mobile while holding vol + and - buttons. It will then show connected in MSM tool for 2 or 3 seconds. Immedeately click "start" in MSM.
This worked for me.
Thanks you guys
it worked for me
I am now able to get into edl mode

Thanks! The trick with a different than the OEM cable helped me. I have flashed a different .ops file than the one on my OnePlus 8 (wanted to transition from T-Mobile to Global), and after that, the phone was booting straight into fastboot, without the possibility to boot into edl or recovery...

How To Guide [CLOSED] Unbrick your phone with EDL mode (no access to fastboot)

Hello guys
Today I'm going to tell you about how to bring your phone back to life when it is bricked and also you don't have access to fastboot.
few days ago when I wanted to turn back to Xiaomi EU weekly ROM from HOS, the fastboot script which is provided by Xiaomi EU team in order to flash the ROM gave me to many errors when it was trying to flash "super" partition and mistakenly I had rebooted my phone and then I realized the the phone is dead, it didn't show any sign of life (I mean no vibration, no fastboot and no screen light, literary nothing at all).
After some research I found out that Qualcomm powered devices have something called EDL which is stand for (Emergency Download mode) and it is there to flash fastboot ROMs when you don't have access to fastboot (as matter of fact EDL mode is one level lower than fastboot and let you to access the phone when it is dead and also it cannot be erased with fastboot).
Important: with this tutorial you can fix your phone by yourself and also there will be no need to pay anyone with authorized xiaomi account to connect to your personal computer and do the flash for you.
Lets head to tutorial:
Requirements:
1- A windows system
2- EDL drivers which can be found here
3- Original USB cable
4- Xiaomi pro tool which can be found here <Moderator Edit>: warning, comes up as Trojan:Script/Wacatac.B!ml in Windows Defender.

4- go to "xiaomi firmware flasher" page on xiaomi pro tool app and locate the downloaded ROM (you should locate "image" folder (downloaded ROM/images)) after that you will see that it loaded files correctly.
5- Disconnect your phone and hold power button for 15 second then press and hold volume up button and connect your phone with its USB cable to boot to EDL mode again and check thee "ports" on the tool app again (it should be same as step 2)

7- The tool will reboot your phone automatically but if you find your phone completely dead after the flashing process(not responding to anything and not going to EDL mode again (which was my case)) just don't panic, your phone maybe out of charge so just connect your phone to a charger and wait, after some minutes you will see the battery icon on your device.
8- hooray, you made it. you can enjoy your phone now

That's great, much better than the €25 I had to pay.
Thanks for the guide.

Hello guys
Today I'm going to tell you about how to bring your phone back to life when it is bricked and also you don't have access to fastboot.
few days ago when I wanted to turn back to Xiaomi EU weekly ROM from HOS, the fastboot script which is provided by Xiaomi EU team in order to flash the ROM gave me to many errors when it was trying to flash "super" partition and mistakenly I had rebooted my phone and then I realized the the phone is dead, it didn't show any sign of life (I mean no vibration, no fastboot and no screen light, literary nothing at all).
After some research I found out that Qualcomm powered devices have something called EDL which is stand for (Emergency Download mode) and it is there to flash fastboot ROMs when you don't have access to fastboot (as matter of fact EDL mode is one level lower than fastboot and let you to access the phone when it is dead and also it cannot be erased with fastboot).
Important: with this tutorial you can fix your phone by yourself and also there will be no need to pay anyone with authorized xiaomi account to connect to your personal computer and do the flash for you.
Lets head to tutorial:
Requirements:
1- A windows system
2- EDL drivers which can be found here
3- Original USB cable
4- Xiaomi pro tool which can be found here
5- Fastboot ROM for your phone which can be found here
method:
1- first you need to boot your phone into EDL mode (you can do this by holding volume up button and connect your phone with its USB cable and check "device manager" on windows to check if your PC recognized your phone or not. you should see "Qualcomm HS-USB QDLoader 9008" under "ports" section (look at below picture)

3- You need to buy at least 5 credits in order to flash ROM on your device you can buy it on the internet just google "credits for xiaomi pro tool" (Iranian users can use this site to buy credits)
4- go to "xiaomi firmware flasher" page on xiaomi pro tool app and locate the downloaded ROM (you should locate "image" folder (downloaded ROM/images)) after that you will see that it loaded files correctly.

that's absolutely i done but for those people who don't have access to buy credit can search patched hose but till now no one has patched for our device poco f3. for patching it requires reverse engineering skill which i don't have.
why are the credits needed? this program is going to be likely used by desperate users that destroyed the phone and they even have to pay? i get the developers need money but its just bad...

The only other option is paying €25 to a random person on the net to tunnel into your PC and do the job for you.
Nice
It's difficult to trust these random programs, but desperate users with bricked phones don't have many other options...
I had to pay 25€ to get mine running again. The fact that you have to pay sucks. It shouldn't be like that.
I paid more than $30 to random person I found on youtube and I still had to disassemble my phone myself to put it on EDL mode (was it really necessary? - since my phone has an unlocked bootloader).
WARNING! Xiaomi Tools Pro contains a backdoor virus
Win32/Bladabindi!ml - Virus​
This will allow the hacker to gain control of your computer and potentially draining your bank accounts/bitcoin.
you have been warned.
I have always bought Xiaomi Products but after reading all the trouble that you have to go through and zero customer support with most software infected by ****ty backdoors, I have to go back to some oneplus or pixel or mainstream phones.
Hello everyone,
I just wanted to say I followed the instructions above and it worked fine. I paid 10€ for 10 credits at <Moderator Edit>: (removed) and I used the tool and everything went smooth with my poco f3. Just like it says in the tutorial, if it does not reboot automatically, just charge your phone for a few minutes and voilá. Just wanted to leave my input in here, so if anyone is in this situation, you CAN fix your phone.
<Moderator Edit>: Thread closed. @raminta look for my PM shortly.

Question [HELP] Unbrick an almost completely bricked phone.

Hey.
This post is my last faith in this device.
So basically I was about to flash partitions, but when I tried to go into fastbootd to flash the critical stuff, after the "fastboot reboot fastboot" command my phone was completely got bricked. I already tried every type of key combinations, the screen was black the entire time, and the phone won't even vibrates.
The only signal of it's being alive, when I plug it and press pwr + vol up, windows gives the sound of a connected/disconnected device, and the MsM tool shows that too. At this point, i was sure about the MsM tool and didn't panicked, I knew that I can almost always unbrick the phone with that... Hmm... This time it was different, because every time I get an error: "Sahara communication failed", or "Param preload", and I cant even do anything. Currently the phone was completely dead.
If you have any idea how to fix that Please let me know! Thanks.

From the image you posted, it looks like you are using the wrong MSM version. "Device not match image".......

I used this exact version on this phone like 2 days ago, I dont think it is a version problem, but thanks for the help!
And it is pretty interesting.. As far as i know EDL connection only alive for 5-10 sec, but currently MsM tool shows Connected until my phone was plugged in (even after refreshing it)

Just like the other posted said. If it says that error, it means that your device ID is different. Did you possibly use the India MSM which would change your device ID and not allow you to use the one you were using before? You can also try unchecking sha265check and check use lite firehose and see if it works that way.

Okay so basically, you're both right. I got the Global version, but with the correct MsM version for that did not worked. The solution was to use the Indian version to unbrick it, then ofc switch back to the global. I took this idea from this post, It's seemed so idiot to do it that way, but I had nothing to lose. Thanks again!

Once you used the Indian MSM, then to go global you have to install the updater tool from Google Play store to choose the version you want and install it that way. I believe.....

I don't believe it's available in play store, have to Google search for it but otherwise your right, once you use the India MSM, your device ID is permanently changed and can no longer use the reg MSM for the device.

Would this not work?
I am not sure how OnePlus implements it, but many devices have a Qualcomm USB mode or "Emergency Download Mode" for performing a low level reflash of basic firmware such as the bootloader. Most often, when a device screen doesn't come on, but it vibrates and a PC shows a connected device, this is the case - the PC has detected the QUSB mode.
Unfortunately, Qualcomm does not make their Qualcomm Product Support Tool available to the public, and most OEMs do not provide the necessary binaries to restore the bootloader. The device cannot be repaired or restored without these tools, unless the mainboard is replaced. Unfortunately in this case, I believe that is your only option.

Odin is for flashing Samsung devices. Samsung and now OnePlus are the only two devices I have worked with.

Not only specific to OnePlus but also specific to OOS versions.
Might try to uninstall Qualcomm drivers, make sure PC driver signing is disabled. Reboot PC, then re-install latest Qualcomm drivers, re-boot PC and try again with MSM tool. The windows sound when plugging in before is the sound of a device plugged in but couldn't recognize it and threw it out of device manager. That was the reason for the TWO sounds you heard. Also try holding down on vol + - and pressing power and holding it down to try to boot into fastboot mode. If it does, flash boot boot TWRP.img and then boot into edl from there with phone connected to PC and MSM tool in start mode ready to flash as soon as device is connected.

I can’t boot in Android and in Recovery mode. Everything working is Fastboot mode. I was trying to “unbrick” phone, installing Fastboot ROM( files like boot.img, recovery.img and so on),but in cmd on my pc shows while using commands like: “fastboot flash boot boot.img” or fastboot -w“, only error “Failed (remote:’Erase is not allowed in Lock State’)”.
Now i want to unlock device state if it is possible.
Remind that phone was just unboxed, so it doesn’t have enabled lever OEM unlocking.
try 'fastboot --set-active=other' or unbrick with MSM Download tool or https://github.com/bkerler/edl

bro just use the msm tool. there's a tool for every variant of the 9 pro (LE2120-2125). Look for the post on our Device xda and use it.

turn off the phone fully, press volume up and down fully for 3 seconds then while still holding those buttons, plug in the phone with MSM open on your laptop. it should immediately detect the device. the phone screen will still be black and thats normal. once device is shown as connected, just select target O2 and start
disconnect usb, let battery drain, ensure it is really powered off, press both volume keys, connect usb

How To Guide OP9Pro - Repository of MSM Unbrick Tools (TMO, EU, GLO, IN)​
Does somebody know how long it takes to let battery drain from 100%?
And maybe, Are there some advices how to let battery drain faster?
You will also need to 1) disable driver signature see this https://www.techpout.com/disable-driver-signature-enforcement/ then reboot computer 2) install latest OnePlus USB drivers then 3) install latest Qualcomm driver then reboot PC 4) start the MSM Tool uncheck 256 and check use lite firehose the click start. 5) start phone in edl mode with button sequence.... MSM should automatically start flashing!
As for edl mode, check to see if you can get to fastboot by holding vol + and - and power buttons down and hold them to see if fastboot loads. This is if you cannot get to edl the button wat as described above.
