thanx to @manaswb

interesting to know, thanks
it might save people from having to use the test points which requires disassembly of the phone

Saludos amigo, me puedes ayudar, tengo el problema en este momento, el detalle es que al parecer no tengo carga en la batería, ¿Como cargo la batería de mi teléfono? o ¿como se que se esta cargando? si no enciende para nada.
En su momento (hace 1 mes) me reconocio siempre en 900E Diagnostic, pero ahora no ya que no me reconoce para nada (seguro porque no tiene batería)
"Ya tengo el cable hecho"
Me pueden ayudar @manaswb
Gracias amigos

same as MI5 edl flash cable

you saved my ass! after an unofficial bootloader unlock on kate, my phone went black. Couldn't do anything. Only 900E mode in windows device manager... it worked!

This worked to get an Orbic Wonder back into EDL model from 900E however I cannot get QPST nor UNI Antroid Tools or other flashers to work with it.

[SOLVED] Need help with fixing unknown model in LGUP

I flashed the Fulmics ROM on my G6 and could not go back to stock using LGUP. Under Model and Port it shows "Unknown" and "Com 5, Fulmics" preventing me from proceeding.
I, however, managed to flash the stock rom from a zip provided in one of the threads. Still when I connect the phone to computer, LGUP says "Unknown" and "Com 5, Fulmics".
How can I fix this so that I can use LGUP again? (I also tried the Flashtool with no success)
Thanks

Go to
Code:
C:\Program Files (x86)\LG Electronics\LGUP\model\common
paste this file there https://drive.google.com/open?id=0B8K3M8fXJmgzX1hMNTBkZ3p2M1E

Did that before. Didn't make a difference.

Yes. I even tried another computer. It appears that something about this Fulmics rom is hard coded into the phone. The developer of the rom isn't responding so I don't know what else to do.

Well, I use Fulmics also and i can say nothing is hardcoded. When you connect your G6, check the device manager on your PC to be sure your phone is detected.

It is detected. I even tried changing the com port but nothing happened. So when you connect your phone to pc in download mode LGUP recognizes it?

Le Pro 3 X720 Stuck in bootloop

Hello ,
Yesterday my phone was at 5% so I wanted tot charge it and it did but only not with the original Leeco charger and cable but with a normal charger micro usb with a mico usb to USB C adapter and it was showing that it was charging . But when I came back 10 minutes or so my phone was stuck in a bootloop and I never had a problem with the phone and I was running a LineageOS 15.1 rom.
My Le Pro 3 X720 is stuck in a loop and I can only get to Fastboot mode.
When i try to go to recovery mode (TWRP) it shows Recovery but after a few seconds it is trying to boot but then it restarts again.
What i tried is to flash a new version of TWRP but after that it is still in a loop and not going to twrp.
I know of the QFIL MODE but I don't want to lose my data.
Can someone please help me ?
Thanks in advance.

Since you changed TWRP
I hate to be the bearer of bad news. But it sounds like your phone was short circuited and something is fried most likely the motherboard. I would forget the data, its gone.
But I would absolutely try QFIL, just in case its a very unusual corruption issue. Sorry.
If it was the battery, the usb card, or just a brick ; your symptoms would be very different.
I has a similar issue last month, when the chip is fried you can still use qfil, see the phone in adb, flash roms etc. But never be able to access Recovery or the system, However, you can access Fastboot.

Hi tsongming,
Thanks for your answer but I changed the TWRP after it was in a loop I tought then it might go to TWRP but that was not the case.
And I am not hoping that it is short circuited but if this is the only realistic option what happend then I am going to try the qfil methode .

Bootloop
Hi tsongming ,
I have tried al QFIL options but it did not fix the problem.
Do you know something else to try ?

Right everything you need is within the qfil. Although I gave mentioned it already its very important that you have all of the Windows protections disabled. Windows 10 has so much potential, but is severely crippled by its monitoring and assistive programs. If you are using programs such as Qfil, Windows security will delete some of the files and it makes Qfil unsuccessful. So again, make sure that every aspect is disabled.
When you open Flash 1.9 or 2.0 or QPST make sure that they are opened as an Administrator ( Right click)
If QPST and Flash 2.0 are not working try using fastboot.bat. This can be loaded while in EDL mode. You need 5.8.26s which comes with the fastboot.bat file.
All you need to do is place the stock Rom on your desktop, unzip the rom and double click fastboot.bat. ( The file name is either fastboot.bat, flash-all.bat or something similar. I don't remember the exact name) But there will only be one file with the option of flashing all so choose it.
The .bat file It will automatically flash all of the boot images to the phone. Afterwards your device will be fully restored to stock.
Here is the file: https://androidfilehost.com/?fid=673956719939836266

Isn't it possible to make this under Linux? It would be easier while windows has so many Antivir and defender tools. Also the USB driver are creapy under windows. I have often problems to see Samsung and leeco phones under windows. Via Linux they appear without a problem.

Fastboot
QPST , Flash 2.0 and fastboot flash where all successful but the phone is still in bootloop so I think it is a hardware problem.

Sounds like your battery is faulty. Had the same bootloop issue on my X727 and a new battery fixed the problem. Got the battery here www.aliexpress.com/item/32892123537.html and received an original LeEco battery with date code in 2016. Battery works fine though, phone charges well and no more bootloops.

Hola, tuve el mismo problemas un bucle infinito de reinicios y ningun foro que tenga una solución, sin embargo al leer que podría ser un problema de hardware, lo abri y encontre un conector ligeramente desmontado,(conector de banda anaranjada, superior derecho, si vez de frente la batería a la par de un código qwerty) lo conecte y listo volvio mi LeEco pro. Lo comparto por si a alguien mas le puede servir, de hecho ya había descartado mi telefono y compre otro, pero siempre queda la idea de buscar una solución.

How to exit EDL mode on Lenovo Tab 4 8 Plus?

I flashed stock ROM to my Lenovo TB8704F recently, but when I rebooted, I ended up in EDL mode. I've searched online for solutions but they all appear to be for other manufacturers and don't work on my tablet. How do I exit EDL mode on my Lenovo Tab 4 8 Plus? All the usual hold power button stuff like that don't work.

Just a guess...but if you're stuck in EDL mode, it should be as easy as using Lenovo's LMSA tool to rescue the tablet. Connect your tablet to the PC when LMSA prompts you to. Don't worry about pressing the Volume Up button, because you're already in EDL mode.
This will flash the stock ROM and wipe your data. At the end of the process, it automatically reboots into Android setup.
If that doesn't work, then confirm you're actually in EDL mode. Connect the tablet to a Windows PC and confirm in Device Manager that it shows as a "Qualcomm HS-USB QDLoader 9008" port device.
The only other trick I know of is that some users have reported that EDL mode's ability to connect to a PC times out after a short period. So reboot your device (if you can) before connecting it to LMSA.

That doesn't sound good. I assume you're using the "powered off" rescue mode in LMSA, and entering the correct Hardware Code for your tablet.
After you connect the tablet to LMSA, does the progress bar move at all? If it does, at what point does it fail?
Did you get any further with QComDLoader and/or QFIL ? Did they give you more descriptive error messages?
Can you confirm the port name for your powered-on tablet in Windows Device Manager? It's usually either "9008" (EDL) or "900E" (diagnostics).

I wonder if it it's a USB-driver problem.
You could try to uninstall & delete the 9008 driver from Device Manager (when you tablet is connected to PC). Then uninstall LMSA and reboot. Reinstall LMSA and see how you go. You should end up with the 9008 EDL driver from Lenovo. That should be compatible with LMSA.

I just tested something: I tried flashing it without the tablet plugged in. Surprisingly, it did exactly the same as I said it had done in my reply, it was at 67% then went to 100% and failed. Therefore, I am beginning to think that LSMA does not recognise the device. I have tried doing what you recommend, but still the same.

If there's a lengthy pause between 67% and 100%, then that's typical behaviour when your connected tablet is not in receptive EDL mode.
Double check that the 9008 driver is the one provided by Lenovo dated 21/10/2014 v.20.0.9.6. You can check in the driver's properties in Device Manager.
Remember to power the tablet off and back on just before connecting it to the PC when LMSA is sitting at 67%. Many users report that if a device is in EDL mode too long, then it won't connect to the PC. The solution is to reboot the device and re-start EDL mode. Sometimes that involves disconnecting & reconnecting the battery - let's hope you don't have to do that.
Try a different USB cable. Not all cables are fully wired.
@AlaskaLinuxUser had some luck trying older versions of QFIL. You could get lucky and find one that works for you.
Otherwise, you might be forced to send the tablet to Lenovo for repair. Something obviously went horribly wrong when you flashed that ROM to your tablet. I wouldn't flash that ROM again.

[SOLVED*] POCO M3 stuck in EDL (No Fastboot, No Recovery)

――――――――――――――――――――――――――――​My Case | The Beginning (November 18, 2021):​――――――――――――――――――――――――――――​
A while ago I unlocked Bootloader from my POCO M3 European [EU] [citrus] and downgraded MIUI (12.5.2.0 to 12.0.3.0) because the update had made the experience worse in several things. I managed to do this and used my POCO for several weeks normally. This week I simply had to Restart the device, and then it didn't turn on anymore. There have been no updates applied, I have not confirmed this. He died and when connecting to the Computer I noticed that he was in EDL Mode (Qualcomm HS-USB QDLoader 9008). From there, after tirelessly searching forums and countless websites, I did this:​
I found the POCO M3 Engineering ROM and through the Firehose File that came in it I managed to bypass Xiaomi's EDL Authentication. I used this Firehose in the Original ROM and managed to install it normally.
I installed the engineering version, I also tried the Original version 12.0.3.0 (oldest 12.0) and also the Original version 12.0.11.0 (latest 12.0), but after successful installation the device wouldn't reboot (stuck in the EDL). [Note: with this method I installed using MiFlash and sometimes I also used QFIL, but the result was exactly the same]. If I used the Power and Volume buttons (different combinations) the device would restart but immediately return to the EDL.
I let the battery completely discharge and the next day I plugged the USB cable into the Computer (and the POCO) and this time it showed the charging icon (battery empty), and a few minutes later the screen turned on by itself (showing the POCO symbol ) and the battery icon appeared "1%" (charging). And so Windows recognized the device as "Linux File-Stor Gadget USB Device" (in MiFlash it was recognized as "c12feb2e0720 device").
With high hopes, I opened the Command Prompt and tried to communicate with POCO through Fastboot and ADB, but both didn't see any devices (fastboot devices | adb devices) and that made any command impossible.
I tried to flash the Original ROMs again (using MiFlash), taking advantage of this "Strange Mode", but it didn't work, because in the first command the software didn't get a response from the device.
I noticed (by the MiFlash verbose) that the flash command was started with "fastboot -s c12feb2e0720...", so to access the device it would be necessary to specify where it was. Unfortunately, using the Command Prompt (as well as MiFlash), I was not successful, as in both cases the device did not "answer/return" anything.

―――――――――――――――――​Workarounds (Jun 02, 2022):​―――――――――――――――――​If your device is under warranty, use it for Xiaomi to repair it. If this is not your case, I have two alternatives that worked for me (the second is the one I use repeatedly with success).
Fully discharge the battery
My device was 11% charged and I simply disconnected the battery cable from the device (manually) and waited for a many hours (If your device is heavily charged, you may need to wait for days for the battery to fully discharge). After reconnecting the battery and pressing the Power button (no USB Cable Connected) the POCO started normally.

Heating the Motherboard
Some time later I had to restart my POCO, but I knew that this would cause the "EDL Stuck Mode". Then I found that overheating a specific part of the Motherboard forced POCO out of EDL Mode and allowed the system to boot. From there, I disassembled my device (the SIMCard/SD Slot, the plastic cover and the protection above the cameras, that order), disconnected the wires that were attached to the motherboard (including fingerprint connector), and removed it. So, I turned it upside down and used a soldering iron to overheat a specific part for 5 minutes (the specific part is in this image). After those minutes, I reconnected everything and simply pressed the Power button, and POCO turned on normally.​

*Note1: Make sure all connectors are properly plugged into the motherboard. Otherwise, Poco will not recognize the fingerprint or some other component.
*Note2: In my case, the 'procedure 2' needs to be used EVERY TIME I need to RESTART my device. And it also serves to apply OTA updates. {For example: when the update appears, confirm it. After it downloads, confirm to apply as normal. The phone will restart and get stuck in the EDL. Then use the above overheat procedure to turn on the device, and during the boot process the update will be applied.}​―――――――――――――――――――――――――――――――――​Flashing the MIUI ROM on EDL (with EDL Auth Bypass)​―――――――――――――――――――――――――――――――――​
The safest way is using "MiFlash". Before starting, download the following files:
- Qualcomm HS-USB Driver (64bit) or Qualcomm HS-USB Driver (32bit)​- MIUI ROM (Fastboot version) (select your device variant: EEA/RU/Global/IN, etc...)
- MiFlash (Xiaomi Flash Tool)
- Firehose File (Bypass EDL Auth)
​
Install the Qualcomm Driver (if I haven't done so), restart the computer; connect your POCO and open Windows Device Manager (shortcut: Windows + X). In the "Serial Port" category, make sure your POCO (EDL Mode) appears as "Qualcomm HS-USB...". If yes, all right. Else, check that the drivers were installed correctly (no exclamation marks) or if your device is being recognized in another mode (ADB or Fastboot). If so, it will show up as "Android ADB Interface" or something similar, and that means your device is not in EDL (This is great news, so continue the tutorial as MiFlash will be able to flash the ROM in the alternate mode of your device. If you can't, let me know.).​
Unzip the MIUI ROM until it becomes a folder. Inside the created folder, open the "images" folder and replace the downloaded "Firehose (Bypass EDL)" file with the one in the folder.​
Run MiFlash, click "Refresh" and make sure your device appears in the device list. If yes, click "Select" and check the MIUI ROM folder (not the "images" folder).​
Click on Flash and wait for the process to complete (the word "success" in green will appear).​
Important: If your device is in EDL Mode, flash will delete all files on your device. But if the device is in ADB or Fastboot Mode, you can flash without erasing your files. Just look at the bottom of MiFlash and click "Save User Data". This script is expected to work.

Sorry, I didn't understand you well :s
Did you mean that if your phone discharges (turns off) it goes into EDL mode?

yes dont turn on again I have to disconnect the battery again for me it's a really it's a deception this poco was a really decent option

Absolutely! Poco is a very good alternative. Too bad the support sucks :/
I don't know how I'm going to solve this problem. I already installed MIUI version 12.0.3.0 as it is the oldest available, but the problem persists. I don't want to lock the Bootloader (it's open) as I worry if the device dies and I can't flash the system again.

can you make a video please! you can save us i guess

I'm getting ready to do this. But meanwhile, tell me what your question is, I can help you.

My question is any permanent fix for this particular problem?
I'm considering buying this phone

I have a question , if you were to try and update your M3 that has the deadboot issue , would it fail all the time? Because we can't reboot the phone or power it off without it going into deadboot. Can we still access recovery?

Good question! I'm looking forward to updating the MIUI version, but I'm sure the M3 will go into deadboot. About Recovery/Fastboot I can't access it, but right now I'm doing some tests to make sure I can access it.

I tried to restart the M3 using ADB on Windows (adb reboot recovery) with USB Debugging but the device went into deadboot, unfortunately. So far I haven't found any solution to update the device other than Flashing via EDL (Xiaomi Mi Tool), replacing the "firehose" file in the ROM folder.

Hace un tiempo desbloqueé Bootloader de mi POCO M3 European [EU] [citrus] y bajé MIUI ( 12.5.2.0 a 12.0.3.0 ) porque la actualización había empeorado la experiencia en varias cosas. Logré hacer esto y usé mi POCO durante varias semanas normalmente.
Esta semana simplemente tuve que reiniciar el dispositivo y luego ya no se encendió. No se han aplicado actualizaciones, no lo he confirmado. Murió y al conectarme a la computadora noté que estaba en modo EDL ( Qualcomm HS-USB QDLoader 9008 ). A partir de ahí, después de buscar incansablemente en foros e innumerables sitios web, hice esto:
Encontré la ROM de ingeniería POCO M3 y, a través del archivo Firehose que venía, logré omitir la autenticación EDL de Xiaomi. Usé este Firehose en la ROM original y logré instalarlo normalmente.
Instalé la versión de ingeniería , también probé la versión original 12.0.3.0 (la más antigua 12.0) y también la versión original 12.0.11.0 (la última 12.0), pero después de una instalación exitosa, el dispositivo no se reiniciaba (atascado en la EDL). [Nota: con este método lo instalé usando MiFlash ya veces también usé QFIL , pero el resultado fue exactamente el mismo]. Si usaba los botones de Encendido y Volumen (diferentes combinaciones), el dispositivo se reiniciaba pero regresaba inmediatamente a la EDL.
Dejé que la batería se descargara por completo y al día siguiente enchufé el cable USB a la Computadora (y al POCO) y esta vez mostró el ícono de carga (batería descargada), y unos minutos después la pantalla se encendió sola (mostrando la Símbolo POCO) y el icono de la batería apareció "1%" (cargando). Y así, Windows reconoció el dispositivo como " Dispositivo USB File-Stor Gadget de Linux " (en MiFlash se reconoció como " dispositivo c12feb2e0720 ").
Con muchas esperanzas, abrí el símbolo del sistema e intenté comunicarme con POCO a través de Fastboot y ADB, pero ninguno de los dos vio ningún dispositivo ( dispositivos fastboot | dispositivos adb ) y eso hizo que cualquier comando fuera imposible.
Intenté flashear las ROM originales nuevamente (usando MiFlash), aprovechando este "Modo extraño", pero no funcionó, porque en el primer comando el software no obtuvo respuesta del dispositivo.
Noté (por el detallado MiFlash ) que el comando flash se inició con " fastboot -s c12feb2e0720 ... ", por lo que para acceder al dispositivo sería necesario especificar dónde estaba. Desafortunadamente, al usar el símbolo del sistema (así como MiFlash), no tuve éxito, ya que en ambos casos el dispositivo no "respondió / devolvió" nada.
Hasta ahora, estos son los avances que he logrado para eliminar los ladrillos de mi POCO M3, pero no sé qué hacer. Seguro que si consigo resucitar mi dispositivo haré un tutorial para ayudar a otras personas, porque esta situación es terrible.
_______________________________________________________
¡YO LO RESUELTO! Después de todo lo que hice anteriormente (el dispositivo estaba cargado al 11%), simplemente desconecté la batería del dispositivo y lo dejé durante unos minutos (sin batería conectada). Después de volver a conectar la batería y presionar el botón de encendido (sin cable USB conectado), el POCO se inició normalmente .
Espero que esto ayude a alguien
* Nota: Estoy usando MIUI 12.0.3.0 (UE, es posible una versión anterior de fastboot) y no quiero actualizar. Para propósitos de prueba, reinicié el dispositivo y confirmé: Se atasca nuevamente en la EDL . Pero simplemente desconecto la batería durante al menos 5 minutos, la vuelvo a conectar y enciendo el dispositivo normalmente, y puedo usar mi Poco . La única pregunta principal ahora es: ¿cómo puedo reiniciar / apagar el dispositivo normalmente sin quedar atascado en la EDL? ¿Cualquier sugerencia?​Si te ayudaron con esta publicación, comenta.

Hi, I have the same problem, I followed your steps, I flashed several ROM'S but nothing so I tried version 12.0.3.0 and I think it worked, I left it connected to the PC, after having flashed the ROM, but I fell asleep when I woke up, I tried to turn it on and the battery appeared, it gave me a life expectancy! immediately connect it to the power and yes! "1%" appeared from there the LOGO OF POCO, but from there he did nothing more ... he stayed in EDL again: c I don't know what to do ...

You must flash the MIUI of the same version as your phone (eg: Europe, Global, Russian,...). The Flash process must be done in EDL mode, using Xiaomi Flash Tool (Mi Flash). In my case it was the "QJFEUXM" ROM.
After the flash, just follow the same battery disconnect procedure you did.

A while ago I unlocked Bootloader from my POCO M3 European [EU] [citrus] and downgraded MIUI (12.5.2.0 to 12.0.3.0) because the update had made the experience worse in several things. I managed to do this and used my POCO for several weeks normally.
This week I simply had to Restart the device, and then it didn't turn on anymore. There have been no updates applied, I have not confirmed this. He died and when connecting to the Computer I noticed that he was in EDL Mode (Qualcomm HS-USB QDLoader 9008). From there, after tirelessly searching forums and countless websites, I did this:
I found the POCO M3 Engineering ROM and through the Firehose File that came in it I managed to bypass Xiaomi's EDL Authentication. I used this Firehose in the Original ROM and managed to install it normally.
I installed the engineering version, I also tried the Original version 12.0.3.0 (oldest 12.0) and also the Original version 12.0.11.0 (latest 12.0), but after successful installation the device wouldn't reboot (stuck in the EDL). [Note: with this method I installed using MiFlash and sometimes I also used QFIL, but the result was exactly the same]. If I used the Power and Volume buttons (different combinations) the device would restart but immediately return to the EDL.

So far these are the progress I've made to Debricking my POCO M3, but I don't know what to do. Surely if I manage to resurrect my device I will make a tutorial to help other people, because this situation is terrible.
_______________________________________________________
I SOLVE IT! After everything I did above (the device was 11% charged) I simply disconnected the battery from the device and left it for a few minutes (no battery connected). After reconnecting the battery and pressing the Power button (no USB Cable Connected) the POCO started normally.
Hope this helps someone
*Note: I'm using MIUI 12.0.3.0 (EU, older fastboot version possible) and I don't want to update. For Testing purposes, I restarted the device and confirmed: It gets stuck in the EDL again. But I just disconnect the battery for at least 5 minutes, reconnect it and turn on the device normally, and i can use my Poco. The only main question now is: how can I restart/shutdown the device normally without getting stuck in the EDL? Any suggestion?​If you were helped with this post, comment.

Many thanks for the link to POCO M3 Engineering ROM, it solved everything with my phone, I was in EDL mode and after installing, reinstalling and modifying the phone is like new, I also repaired another phone.

Glad it worked out for you!
But I have a doubt: you said that the cell phone "was like new" after (...) modifications.
1. Does it mean you can restart your phone normally without getting stuck in EDL?
2. What changes did you make?
These answers can help everyone who is experiencing the problem.

I have restarted the mobile phone many times after the repair, when installing the rom and the applications works perfectly.
After flashing via Flashtool, I immediately installed TWRP via Fastboot and installed Miu 12.5.3.

It really is a very interesting situation. In my case, ever since I got stuck in EDL for the first time I was never able to restart the phone again. Despite installing the Engineering ROM, the device can no longer access Fastboot Mode or Recovery Mode. The only thing I can boot is the System, and if I restart the phone I will need to open it and heat up a point on the Motherboard so that it exits EDL and boots normally.
My device is an EU version, and this week I installed the MIUI version 12.5.5 (Global) via EDL (with a Fastboot ROM) as it is the only method I can flash...

Interestingly, my cell phone got into the bootlop by installing the wrong Rom, when it couldn't, just boot through EDL by connecting two points, it didn't seem logical for me to fix it by discharging the battery or destroying components by heating.
I used a modified MIFLASH DRIVER, Qualcomm HS-USB QDLoader 9008 and POCO M3 Engineering ROM. Also when repairing another mobile phone.
The phones are working perfectly so far.

Got it! Do you know what modification was made to the Driver?
And from what I understand, you weren't exactly stuck in EDL, you were actually in Bootloop. That's right?
