EDL (Emergency Download) Mode has been removed/ disable from MIUI 8.1 onwards and Redmi 4A later Xiaomi devices. So you can flash MIUI Fastboot ROMs on your device by using Fastboot mode only, if your bootloader is unlocked. And, we can't use Qualcomm Jig Cable(s) also now.
So, we have only one way to know Qualcomm HS-USB QDLoader 9008 port from PC. It's Test Point Method. This method will work with every MIUI ROMs (Upgrade/ Downgrade) , Locked Bootloader/ Unlocked Bootloader and also work to recover from a Dead boot device (Bricked).
While touching these two points with a metal tweezers plugin the usb cable to the phone and PC will make the phone enter edl mode. You can then release the tweezers.
Bro edl mode is not removed. It's just moved to fastboot. You can enter edl easily by "fastboot oem edl" command. Hope this helped :laugh:

In any case, the bootloader muz be unlocked to initiate EDL using ADB fastboot..

What makes you think I'm so lame as well. I have used this command and flashed my mi max 2 with fastboot rom. Tho I don't remember if bootloader was locked or unlocked. Probably it was unlocked. But still no issues as anyone can unlock thier bootloader officially.
i wasnt intended at you. it seems they forgot some ways when they first deployed the edl blocking access but with the most recent "roms" they have blocked every access way to edl when bootloader is locked : adb, fastboot & cable
the only way left is from internal pins, but we can expect they will hide them even better on new phones.
Today it's much worth to wait 72h (+30days if you just already unlocked another one today) than opening the models that have "non removable" batteries and risking to leave traces/damages
it's really a shame that xiaomi lock their phone this way, it's a very bad message at the users (fastboot is so much restricted that you cant even switch between stable&dev anymore with locked bootloader) but we still have the chance that they allow unlocking and that this unlocking is a real one allowing full control
Fastboot rom isn't needed untill we brick our device and we can't brick the device untill we have unlocked bootloader. So basically edl mode will work when it's really needed.
It doesn't work for my MM2. Got it since 4/12/17. Didn't know i need to login to mi acc to register my device, set usb debugging, developer's mode, unlock status...I had the phone for less than 2 hrs after updating to MIUI 9 from ver 8 (using the updater app) before it suddenly froze up, crashed and went into bootloop. I tried contacting xiaomi svc ctr but those clowns refused to help saying my device is china export.
I cldn't even get them to help me register my device on my mi acc using the imei & s/n info. So if anyone could offer some suggestions as to how I could ressurrect my phone, I wld be most grateful. Failing which the only avenue is to bring it to a svc ctr in China to get them fix it.

My test points don't seem to work
I opened up my mi max2 and followed the steps to short the testpoints but my pc doesn't seem to pick up the Qualcomm device.
Anyway to trigger the thing so that the Qualcomm device can be detected?

I managed to short the test points and got the Qualcomm HSB device on the device mgr, flashed the mi max2 with the latest global stable (V9.2.1) rom. But the phone is still stuck at the Android logo with 3 dots...
I wld have thought EDL flashing wld have wiped out everything on the phone and start afresh?
I am now thinking of formatting the entire phone and reflashing it again. How wld I do that?
Thanks for any inputs.
Hi, Does EDL with test point flashing refresh the boot partitions?
I have shorted the test points and successfully reflash the phone with the latest stable global ROMs (even back to MIUI 8.5.6) but just couldn't get the phone past the MI/Android logo after restarting it
If the boot partition files have been messed up and EDL flashing is not refreshing these files, no matter how many times I try to EDL flash the device, it's not going to help. Pls correct me if I am wrong.
Any other options I can try?

Hello I am posting in Q&A because I'm a new XDA user, I was not allowed to post in the dev channel.
I have an Essential phone that has been working great for the past few years, no issues, and it was running standard build receiving OTA updates, until the very last update, which soft bricked the phone.
The phone was never enabled in developer mode while in Android, and now, I can't boot the phone into android at all. The only thing I can do is get into fastboot.
Fastboot state shows DEVICE STATE - locked
Any commands I try to unlock flashing, or change slots, anything at all, I get the error that the device is locked so all commands to unlock fail.
Is there any way to unlock device state from fastboot? I saw a youtube video showing a way to use a chopped USB cable to enter emergency / EDL mode for Qualcomm-based Android devices, but have not seen anyone post that this was successful with the Essential
Does anyone know of any method to be able to unlock flashing from fastboot? Or any other method to un-brick an essential? I've attempted everything, on both Mac and PC, nothing works.
On mac or PC, I can query the device in fastboot and get a response, I just can't do anything to unlock anything!!
Many thanks in advance for any suggestions!
Same problem
Same thing happened to me. Same day as you. I can get fastboot but not adb but since the device is locked I can't flash. I've only had the phone about 6 months so I contacted customer support and they offered to replace the phone.
It might be a known issue because they didn't even try to address the fact that I could get fastboot connected but not adb. They just offered to replace.
Thanks for the info! I am -at least in this case- unfortunately an early adopter. I bought two essentials at the beginning of the pre-release.
Essential support checked my serial number and said the phone was out of warranty.
Has anyone been able to force the Essential into EDL mode to recover that way? It looks like you have to latch one of the USB pins to ground, or 5V, but I haven't found any detailed instructions on how to make this work on the essential...
Thanks again
Justin
I'm sure things have changed and I'm wrong, but if you can get into the fastboot menu can't you just cycle through the options until you get to recovery and then flash an official release from Essential?
I may be thinking of LG or something but this should be possible as long as it's newer than the current software installed because it will see it as an official update and allow the flash.
Thanks but unfortunately, when I try and do that, the phone just does the same thing, it hangs forever on the initial boot screen white Android text with the circle/square logo...
That's why I've been looking into the more direct hardware version of forcing the phone into EDL mode, which is supposed to be possible with all Qualcomm based phones.
I've just not found the time yet to find a USB-C cable I'd be happy to cut in half and short the pins on! Which is why I was hoping someone might have tried this with an essential before to know if it was successful before I start trashing good cables
Thanks again for your reply!

I have the exact same problem,
My phone is stuck on Essential log when I turned it on,
I can access Bootloader normally but the device is locked so I cannot flash it,
Recovery is corrupted, when I try to star it, it shows only the the Essential log and freeze so I can not format or wipe or sideload.
OEM Locked and unchecked
USB Debugging is unchecked
and I can't flash anything,
Did you managed to unlock it through Fastboot command or any other way ?
I wish I can just login to the recovery or unlock it so I can flash it clean,
Kindly help me if you found a way out
Thank you
Hello guys,
I'm fairly certain I'm stuck in an un-debrickable state but I'll ask just in case. My phone is F800K.
I was toying around with LGUP in order to downgrade and root my phone. So far, so good.
I then tried to update to the latest android 9 again, but keep the root active. That's where things started to go south, so I decided to go back.
I followed a couple of "back to stock" guides but now I'm screwed.
- The phone does not boot.
- Download mode is broken, the phone doesn't connect to my computer while in download mode, so it's unusable.
- TWRP is gone. When I try to boot to recovery after yes both times I get nothing. Not the stock recovery and not TWRP, it just tries to boot as usual.
- Can't seem to go back into fastboot either. I tried VOLDOWN + plug-in the phone about 200 times now, to no avail.
Is there another way that I'm missing ?
Thanks.

It does sound like a hard brick... you said fastboot is hosed, do you have access to adb in any way?

None that I know of, that's the issue. If I had access to either fastboot, adb or download mode, I could most likely salvage this, but I can't seem to be able to.
The weirdest thing is the broken download mode, I couldn't find anybody with the same issue...

On my lg tribute HD (ls676) fastboot was removed by lg themselves on Android 6.0.1 quietly with a security update and download mode never worked right for me. Without access to fastboot, adb or even diag mode it really sounds like you have a hard brick. if i can find a solution of some kind, I'll definitely let you know.

What would "diag mode" be and how can I check if I can access it ?
Small update for people who stumble upon this thread, I managed to save my phone by using the Qualcomm Test Point, see here: https://forum.xda-developers.com/showpost.php?p=81697447&postcount=128
i attempted to root my zte maven 3 with zpst for at&t and when the device went to restart the screen stayed black and no matter what key combinations i try i cannot get the screen to turn on. The only thing the phone does is connect to the pc and makes that connection noise. it connects as Qualcomm HS-USB QDLoader 9008. does anyone have any advice or suggestions that might help
Did you make any partition backups in QFIL by any chance? If not, I have no idea how one would go about fixing it. What's your bootloader version? I can try to give you my partition backups and you can try flashing it and seeing if it'll boot.
Tbh I should write my own rooting guide, because the existing methods are, quite frankly, ****ty and dangerous. To anyone reading this, please open QFIL and make a backup of all of your device partitions before messing with anything; this is basically creating a bit-for-bit backup of the storage itself, such as the persist partition, userdata, system, etc. I had to buy a for-parts Maven 3 from eBay because I bricked my Maven 3 using the same guide...
And don't use ZPST from now on. You don't need it. Everything can literally be flashed as a partition in QFIL easily. This is how I safely flashed a Magisk boot image (partition) and half-working TWRP recovery partition.

Your device is in EDL mode. It's the only mode that connects as Qualcomm HS-USB QDLoader 9008, and EDL mode doesn't display anything on your device screen. Just take the battery out for a second and you should be able to boot normally.
I'm going to post a new thread in this forum as soon as I send this, where I'll run down the steps I took to achieve root on my Maven 3 just this morning. I've powered off and booted up about 5 times since rooting and it's still rooted.
I have edl mode no boot no screen no lights, what do do next. I tried removing battery no luck

I am unsure of what you can do because iirc i faced the same issue. I have full partition dumps for my current maven 3, some of which (except for example persist) I can send and you can try flashing it using QFIL since your device sounds like it's in EDL mode
hi guys, i have a oneplus 8 pro model phone. I tried to install OTA with a program called Fastboot Enchancer. However, after the installation was complete, my phone did not turn on again. Fastboot mode, and recovery mode won't boot. It doesn't open in edl mode, which is the only one I trust and use often. When I connect it to the computer, it does not respond at all. I have done recovery with edl mod many times with MSM tool, but now I can't. Looking forward to your help and ideas.
If your device no longer ever appears as a USB device and the screen is not helpful and you've tried all the "magic" gestures like holding down 3 buttons and standing on your head, then you'll have to do something different.
This kind of thing happens when something is broken, but it's not broken enough that it realizes that it's broken.
Life is easier when it's totally broken.
Possibilities are:
1) find the EDL test points inside and connect them while reseting.
2) disable data lines or clock to the flash so that it can't read anything and knows that it can only go to EDL.
3) JTAG to fix the problem or else just wipe the SBL so that it goes to EDL.
4) Use a USB UART. Maybe it's getting as far as u-boot and you can stop it and make it go to fastboot.

Sometimes you have to hold VolUp + VolDown + Power for a long time before anything happen. As far as i know we dont know about any EDL points ant the op8 and we have the button combo anyway.
SInce you post on the op8pro forum you probably have a op8pro (obviously) and since you used fastboot i guess you simly hard bricked you phone beyond repair. Your phone RAM is overvolted and dead. And i dont think JTAG or anything else next to a motherboard swap can help you here.

Is there any documentation of the OP8pro about the steps you mention? For example we had a discussion about edl points some days ago and the guy could not find them. And we came to the conclusion the wont help because we already have the button combo.
If the ram is overvolted and fried, which is most likely the case because anything else wont keep the phone away from EDL. Nothing can help to repair a dead ram.
I was listing 4 alternatives above.
Why do you think the RAM is dead?
EDL itself doesn't use any external RAM. There's a bit of static RAM on the chip and it uses that.
