By coincidence I encountered for the first time this problem too. Phone was connected, flashed something but by some sort of action I did (really have no clue), the phone became stuck in edl mode. Could not boot, no leds,,,,nada.

Never had this before and the only way was to drain the battery overnight and redo the job again.

Axon 7 EDL Tool - Unlock Bootloader in the EDL mode

Thanks to djkuz for this very useful tool. I have used it successfully numerous times but I've recently hit a roadblock.

I'm attempting to unlock bootloader. I have read all the instructions and followed them to the letter. However, now the tool executes every step up to the screen showing "Loading the programmer: prog_ufs_firehose_8996_ddr.elf". At this point it hangs.

Any suggestions to solve this issue will be appreciated.

My phone is ZTE A1917G, running the B03 version of Android Oreo 8.0.

Axon 7 A2017G Brick. Please HELP !!!!

- I have Axon 7 a2017g with Unlock Bootloader

- I went from Official V1.3.0B03 (oreo 8.0) to oreo 8.1 and root

- I tried to get back to Official V1.3.0B03 (oreo 8.0) from recovery with sd card. The installation was successful but the device was stuck at the first boot. I could not take any action and neither did the computer "saw it".

- Once the battery to be depleted , it is finally displayed on the computer

- I installed A2017G_B12_NOUGAT_FULL_EDL and A2017G_B10_NOUGAT_FULL_EDL with Axon 7 EDL tool but none of the two did not work. I'm trying to turn on the phone or go into recovery with VOLUP + Activation Key but it shows the blue ZTE logo and then blinking instantly the green robot with the open door instantly and turning it off.

- I did an official TWRP from Flash -> Flash Recovery and the recovery worked. I did WIPE even at internal and installed again A2017G_B12_NOUGAT_FULL_EDL but the device was stuck again at the first boot.

- I wait the battery to be depleted to turn off the device and try again.

- I installed A2017G_B11_MARSHMALLOW_FULL_EDL but asked me for an Android Code and could not enter. I did WIPE again and now nothing works. No EDL, No FTM, No ADB, No Sd Card. NOTHING.

Please HELP !!!!

A hopeless guy

Hi djkuz,

First of all, ths a lot for the tool and the dedication to help :)

I will explain my current status of the complete newbie with any others issue of disassemble the hpone ;'(

Few months ago I begin to have a lot of problem with my Axon 7, and didn't have time to do something, 5h-22h don't let you a lot of time xD and I needed the root on the phone for some works apps.

Yesterday I told myself you need to do it so I try to flash a phone with a french procedure (I'm french), It didn't work and I get a softbrick. Remember it's my first time doing it ;)

I found your tool, so I follow all instructions, miracle the phone were unbrick and I was in oreo yeepee ! But some apps crahes, no root, no TWRP.

So I told myself after seeing this the post of Rayvis - LineageOS 15.1 - on reddit I will try again. And also because I keep getting "Loading the programmer: prog_ufs_firehose_8996_ddr.elf" in all sections no matter what I do.

The first step were fine, until this one

"Once the flash is complete, you can close MiFlash and return to the Axon 7 Tool. Out next step is going to be to unlock the bootloader, which again WILL factory reset your device. Hold the Power and Volume Up keys to boot the device into Recovery mode."

It never work and the phone stay black, can only see it in com, in your program but that's it. Right now I'm trying to drain the power out to see if it can work (some said it worked for them).

I'm the most stupid guys on this planet becaus I can't affort a new phone, need one, and do **** so can't use mine anymore, I must confess, I'm hopeless....

The only solution I see is to disassemble the phone but maybe you got an another one.

Thank you in advance and have a better day than me :D

PS: I got the G version
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Choose an username...:
What do you see in Device Manager as the COM device? Qualcomm HS-USB QDLoader 9008? If so, right click on it and "Uninstall device" (Also tick the checkbox that says "Uninstall driver software" if you see it). After that, enter EDL again on your phone (or turn it off and put it in EDL again) and the driver should get reinstalled.

If it is the Qualcomm 9008 driver then you can try again with EDL Tool or some MiFlash versions (the latest miflash version from google works very nice too, and sometimes EDL Tool fails but MiFlash doesn't, sometimes vice versa... just try). If you see another driver (namely ZTE DFU Handset Diagnostic Tool) then edl tool should supposedly be able to get you out of this mode (you'd be essentially in DFU) but I couldn't get it to work - what you should do is use MultiDL (also in these forums) and that will get you into the real EDL, and then attempt a flash with MiFlash.

Also. If a MiFlash flash fails, hold all 3 keys for about half a minute until the red light flashes and the device manager refreshes. This is essentially rebooting EDL. For some reason it usually stops working after a bad flash

Thanks to this tool, I was able to get a working OS (7.1.1) on my phone.

Since then, this app just closes when I go to unlock bootloader. I hit OEM unocking and have USB debugging enabled, but it still closes down once I hit the button.

Any reason for this?

also, when I start the application, it says cannot find important files for this program. But I literay just extract the zip on the desktop?

If you're trying to roll back to stock from LOS 15.1, first of all download the PARTY tool , and flash it in TWRP. Remove your vendor partition, and then reboot to EDL mode. Now you can try EDL flashing B35 Nougat. Make sure before you boot, you go into the stock recovery and select 'Factory reset' and wipe the data. After that, you should be all good to go.

OREO EDL and unlocking bootloader?

Hello -- first and foremost, this tool is fantastic. big thanks.

A2017U Axon7

I have successfully applied A2017U_B20_OREO_FULL_EDL

phone boots fine into OREO and I follow steps to enable USB debug and OEM unlock.

I use this Axon7_EDL_Tool to attempt to unlock bootloader, SUCCESS is reported in tool, but phone reboots into the dreaded GREEN ZTE logo twice and results in screen below. Note that status is LOCKED.

I'm confident I can fart around and get devices back into DFU/EDL and use tool to apply EDL (again).

Do I recall correctly that ZTE make it more difficult to unlock bootloader in more recent ROM's that that I should go back to NOUGAT or similar?

thoughts on next steps? much appreciated.

Help I can't start /restart my Axon 7

HELP!

After 2 successful flashes, my Axon doesn't want to (re)start!

Axon7_EDL_Tool still sees it and when you start the program, it also shows the connection.

Backup test does not run either.

How should I bring it to life?

I can disconnect and connect the USB cable, the Axon7_EDL_Tool starts, but I cannot make a backup.

Otherwise I don't dare to go on...

What should I click to restart my phone?

I have clicked on 1. Flash -> 3. Flash Recovery to test it.

The partitions are read, as you can see on my picture.

Then came the message, as on the next picture.

Unfortunately, holding the OFF button does nothing.

My Axon does not want to switch itself off... and switch on

best regards

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] runninghamster:
Leave the Axon by itself for up to 24 hours. The battery should eventually drain by itself, and you'll be able to turn on the phone.

If you're in a pinch, you can also open up the phone and disconnect the battery ribbon, which will obviously power off the phone.

Charging for 30 mins is in no way going to be enough for a full backup/flash. Let the phone completely die, to the point where you cannot turn it on via the power button. Now try plugging it into the computer, and try the EDL Tool. If you can't load the DDR.elf file, use another USB port.

Your mobile phone that can't be switched off/on is just the phone in EDL mode.

This phone is completely unbrickable unless from a hardware fault.

Thank you very much for your tips,

I'm afraid I can't get any further...

1. Yesterday I charged an hour too.

After reinstalling the drivers, I saw the phone in the data manager.

2. Since yesterday 21 o'clock until today 16:30 o'clock I disconnected the mobile phone from the charger or USB PC.

Today 17 o'clock I connected it to the charger. The LED looked for 30 seconds. Then the LED was off and the phone vibrated.

But to switch it on does not work!

Reacts to no more mobile phone key!

Nothing can be done. It is dark.

3. After 30 minutes loading time, I have connected the phone to PC.

It is recognized in the device manager.

A recovery

via MiFlash 2016.12.22.0 ends with an error after 110 seconds.

4. The phone remains in EDL mode and does not want to leave it.

Software must be used to force the phone to restart or exit EDL mode.

But how?

Thank you for your help and many greetings

I'm not sure why it's not exiting EDL mode, that's pretty strange. I think it would be best to leave it to the side for 48 hours to ensure a complete drain and then plug in the phone to the power outlet to see if it powers on. If it still seems stuck in EDL Mode after being drained completely, then something is corrupted software-wise. Usually the device gets out of EDL mode after leaving the battery to drain or disconnecting the battery cable from the inside.

Have you tried holding Volume Up + Power for 30s whilst in EDL mode? Sometimes it reboots out.

You could also try to plug it straight into the computer after draining it completely, and then opening Device Manager to see what it shows up as under 'Ports'.

Power off your device, and then hold both volume buttons whilst plugging in the phone to the computer, make sure to do this all at the same time.

Your phone will blink a red led, and then it'll be a black screen. Your phone is now in EDL.

You can flash whatever you like from here.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] murtaghm:
Hi, thanks for replying.

I'm not fully understanding what to do here, I have followed your advice but the EDL Tool I think is still in the automatic unlock state waiting for my phone to boot into the system or fastboot so is looking for an ADB interface which it can't find. Should I come out of the EDL Tool and start again?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] runninghamster:
Do you have the proper Qualcomm EDL Drivers installed? Do you have adb installed?

Check, and then go back to the A7 EDL Tool. If you're only flashing an edl package, it doesn't need adb access or fastboot. Only reason you would need them is if you were unlocking the bootloader.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] murtaghm:
Yes to drivers and adb, my plan was simply to unlock the bootloader, flash TWRP and flash SuperSU, I just wanted to root the device.

EDL Tool all connected via adb and rebooted my phone to EDL, I selected unlock bootloader which I'm sure stated it was successful but now I'm stuck as stated above and EDL Tool can no longer see my phone via adb.

Basically the phone will only boot to fastboot or recovery but adb won't recognise the phone anymore.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] runninghamster:
Make sure you've confirmed that the bootloader is 100% unlocked (you should see a message everytime you boot), in which afterwards you can reflash B03 using the EDL tool. There's links for the package in the OP and also instructions on how to flash it.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] murtaghm:
I don't think the bootloader is unlocked, after booting it goes straight into Fastboot mode, at the bottom in red is states : Device State - locked.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] runninghamster:
Alright.

Connect your device in edl mode to the computer, and use the tool to flash any nougat rom.

After flashing nougat, boot to it and go through be setup quickly. Go into settings, and in developer options enable 'oem unlocking' and 'usb debugging'. Now you can connect the phone to the computer normally, and use the axon 7 toolkit to unlock the bootloader, it should be a simple button.

I spoke too soon, I've really gone and broken it this time.

So I'd got to Nougat with TWRP and Root, all was good.

Then flashed Oreo.

That wiped out TWRP and Root so I thought it would be EDL tool to flash both again in Oreo.

After booting in EDL mode for the Axon EDL Tool, it has just bricked my phone.

I can't power it on at all, no recovery, nothing. I can get to EDL mode but that's it.

So I've tried to MiFlash back to Nougat again but MiFlash when flashing states it cannot read 'hello packet' and fails with a timeout error.

Where do I go from here?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] raystef66:
Drain the battery until you see a red led blink 1 time. Just hook your phone to your pc again and you should be able to flash again.

Tip : drag your twrp into the flash /full (rename to recovery.img), so when you flash again all will be OK.

Btw, if your phone should be in dfu mode (look in dev manager), use the dfu tool to get it back to edl mode. Read thread about it.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] murtaghm:
Thanks I'll give that a go.

How do I drain the battery? just leave it unplugged? if so how would I see a red led blink once? how would I know how much charge is in the phone and when it's about to drain completely?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] raystef66:
First impression is that your phone is stuck into EDL mode.

But first check in dev. manager if your phone is seen as qualcomm..9008 or DFU. If DFU use the DFU tool to get out of DFU and flash EDl rom in EDL again.

If your phone is seen as Qualcomm 9008 and you can not flash in the EDL tool anymore ( hangs on loader...), you're most certain EDL stuck. You could try another port, cable, restart....but most likely you will have to drain.

Drain = just leave your phone overnight. Check when using POWER button. If a single led blink occurs your phone is drained. Hook it back on pc, restart the EDL tool and flash your Oreo + twrp recovery (which you have replaced ofc) and flash.

Btw, most important, relax, our phone is unbrickable. These things happen ;)

So the good news is after draining the battery I could flash Oreo again.

I can then flash TWRP, but that asks for a Password when booting recovery (Mount - Decrypt Data)

If I just cancel the password request I can flash SuperSu, I'm using SR5-SuperSU-v2.82-SR5-20171001224502.

After flashing SuperSu via TWRP the phone won't boot to system and I have to repeat the whole Flash Oero again.

Is there a specific version of SuperSu I should be using for 2017G on Oreo?
