phone is bricked, can't boot into edl - ZTE Axon 7 Questions & Answers

so I had an a2017g MM, unlocked bootloader and installed twrp using the toolkit, tried to "trebelize " the phone using nfound's guide, followed all of it till installing his twrp, when i came to installing the aex aonly gsi, it kept telling me that it can't mount /system (that was after wiping /sys /data etc..) . after that i said "fudge it" and wanted to go back to stock, tried miflash, kept telling me that COMn doesn't work... so i opened the toolkit and chose to lock the bootloader, now the boot loader is locked, the phone is bricked, it just blinks when I charge it, can't access edl (well when i press the button combination, it flashes the led and the pc detects it as QUSB Bulk but miflash doesn't detect anything. So, any help?

Downgrade brick

I have tried to update to nougat but the camera didn't work even after restoring product_v3 on my l31. I tried to downgrade using the suggested oeminfo and b151 rom.
Now i just get the "Your device has been unlocked and can't be trusted screen". At the bottom it says "Your device is booting now..." but it never boots.
I can't install anything via dload method as three button combo just boots to this screen. Power and volume up same screen... Power and volume down same screen... Can't boot to fastboot but thinking maybe that's because the phone won't actually switch off.
I've left it for ages and it's still stuck on the same screen.
Any ideas?
vns-l31 ? l21?
Disconnect the usb cable from the pc, turn off hisuite.
Reconnect the usb cable to the pc to see if it starts.
If it starts not to turn off.
Reset bootloader with fastboot or toolkit 0.0.0.8.
Started fastboot or toolkit0.0.0.8, plugged the usb cable and hold depressed volume - and power. He should go.
Code bootloader and twrp meticulus
L31 as I stated above and the phone is stuck on booting screen. Won't turn off and won't boot to fast boot I've already tried.

Thanks but that app just flashes partitions in fastboot. If I could get into fastboot I could flash partitions anyway

Have you tried volume down pressed whilst connecting to pc?
Yes of course but it just reboots to the same screen not the fastboot screen.

Sorry if it was a silly question to ask...went through all this myself earlier (except mine would power off...) but you said "Power and volume up same screen... Power and volume down same screen..." that's pretty much what mine did and I thought myself "why can't I get into fastboot", but power off and then [*without pressing power* vol down whilst connecting usb] worked.
If I restart my phone from the power menu and then immediately press vol down and connect to pc it boots to fastboot so it doesn't need to be powered off :good: but it does need to be connected to pc with the required drivers installed.
Finally got fastboot working and bootloader is unlocked but can't get anything to boot. Neither MM TWRP or Revolution TWRP will boot up.
Not sure where to go.
I've even tried extracting B151 and B161 and manually flashing boot recovery cust and system in fastboot but still no boot up...

Bootloader, twrpmeticulus, wipe, check all and wipe, install c432oeminfo.zip badwolf (see htcmania), turn off, restart with Dload b130,I read is b130 is best, b150, b160, b161. No matter it works all for me.
Strange thing is whenever i flash meticulous twrp it won't boot. I've tried through revolution recovery and by fastboot!
I can now actually get revolution twrp to boot but it doesn't mount system properly so won't flash anything at all.

7.in recovery go to reboot-> reboot bootloader
8.flash stock nougat's recovery with fastboot
https://drive.google.com/file/d/0ByQ...RYVXdKaU0/view (thanks to @algnerd )
9. reboot to recovery and do a factory reset (if you dont do that your phone will fall in a bootloop)
I think i've seriously messed it up now can't access anything again now just stuck at Your device is booting now... again after trying downgrade method again...
Yeah completely broken now no fastboot, no operating system, no recoveryand no dload. Just boots up to Your device has been unlocked etc and Your device is booting now...
Try to boot one more time to bootloader holding vol down and plugging usb without powering up phone. Then you need to flash twrp for nougat and flash oeminfo trough adb sideload. Do not reboot your phone after this, it won't start. Go back to and copy any app file (for example b160) then try to boot to bootloader and flash boot, recovery and system from nougat app file. Reboot phone holding all 3 buttons, it gonna take a while to boot and it should flash the system properly.
Literally can't get bootloader at all now all i get is the your device is booting now screen and nothingness...
Seriously messed up first phone i've ever bricked and i've been around android since my htc tattoo a LONG time ago
Made the mistake of paying for Phoenix DC as well but that's no use without bootloader mode so waste of 15 euros.
And now i get fastboot again but it says frp lock. DC Phoenix has flashed b151 and b161 but neither boots.
Dload method still fails...
So if now u can get to fastboot, u must unlock bootloader again (frp lock) flash twrp for nougat, copy app file to dload folder, flash oeminfo via adb sideload etc. Look at my previous post.
Send me a message, maybe i can help you..

Honor 8 Lite PRA-AL00 heavy brick, need help

I had EliteTWRP 3.2.1-0 and restored the official rom from twrp recovery but it was stuck when trying to first-time configure the phone(it wouldn't get past the wifi setup). So I went into twrp to try and format everything and try to flash a different ROM and I faced another problem. Internal storage couldn't be mounted. I wanted to fix that by flashing the twrp 3.1.1 because that worked for me before. I got in the fastboot mode but it said that the phone is locked. That was strange to me so I tried unlocking the bootloader with "fastboot oem unlock [my unlock code]". The prompt came on screen asking me if i wanted to unlock boot loader and factory reset and I said yes. Then my phone restarted and is stuck on "Your device has been unlocked and cant be trusted. ...mod=restore page... Your device is booting now...". From that point it's stuck on that screen and I can't get into the recovery or fastboot mode. I tried the dload method(holding volume up volume down and power button) but that did nothing.
Please help.

A2017G only EDL mode available, need help with brick

Hello
Long story short, i digged out my axon 7 to use it with some music apps.
I wanted to return the phone to stock firmware, it had unlocked bootloader and running a custom nougat rom (AEX i think).
I followed this thread: https://forum.xda-developers.com/axon-7/how-to/guide-axon-7-universal-unbrick-t3814413 and flashed full EDL package.
Now when i try to turn on the phone, or enter recovery i see the boot logo and quick flash of the commandpromt with a broken droid and the phone turn off again.
I can still enter EDL mode and flash the phone.
Any ideas how i get it up and ruunning gain ? preferably on stock firmware
Thanks

Use one of the less archaic methods:
Download "EDL Tool" from the ROMs, kernels, development section, along with an EDL package that goes with your phone model. Put your phone in EDL and just flash it with that tool. after that, if it still doesn't boot you have to format data, because you might have conflicting data. If you can't do it from EDL Tool (i think you can, don't remember) just enter the recovery with Vol+ and Power and make a factory reset
My story is very similar and now i'm stuck in EDL mode. I was able to flash stock Oreo B02 EDL package successfully and boot into OS. But after i was trying to unlock bootloader and reboot to recovery, ZTE logo appears for a second or two and then following error message starts looping:
(broken droid logo)
No command
Supported API: 3
E:failed to mount /cache: Invalid argument
E:Can't mount /cache/recovery/last_locale
EDL mode works but if i flash EDL package or boot/recovery again nothing changes, i still get the same error. Can't boot to OS any more and recovery does not work - screen just stays black.
So what are my options now to get it to work again?
From some other threads, I believe you could try to EDL flash Nougat instead of Oreo, it would work better.
https://forum.xda-developers.com/axon-7/help/help-edl-factory-restore-stuck-device-t4031619
I did that already but no luck, i still end up with the same error.
Is there some way to reformat or clean up internal storage completely in EDL mode? It seems that some garbage left behind by trying to unlock bootloader is surviving even EDL ROM flash and breaking OS boot.

According to other threads, the problem could be due to "sparse" structure while flashing.
I suggest the following:
- Use Axon 7 EDL toolkit to flash latest official TWRP recovery (for Oreo a specific TWRP would be requied).
- Inside TWRP then wipe data/factory reset and at the utmost Format data. Then retry to boot.
- If not OK, reflash with EDL full ROM and try again.
Already done that for several times with O ja N EDL rom's but no luck. Can't get to recovery nor make system to boot.
Did you successful unlocked bootloader?
If not, I would recommended Axon 7 EDL Tool by djkuz, flashing nougat edl package and unlock it through the options.
Can you get into stock recovery after flashing EDL package? It supposed to have a format option for userdata and cache.
Did you try to get into fastboot mode? Power + Vol up buttons if i'm not wrong.
If so, you could try to format these partitions.
fastboot erase /cache
fastboot erase /data
I have experienced the same problem but I have resolved flashing, with Xiaomi MiFlash (sometimes I use this program because occasionally flashing EDL packages with AxonEDLTool, it gives me problems like this) this package Axon7_RR-O_B32-B10_TREBLE-Ready_Oki20180803_FULL_EDL.
With this EDL, if the flash is successful, you will find NFound recovery 3.2.1-7 installed with which you can make a complete wipe and / or format them with the file system you prefer.
Afterwards, using MiFlash or EDLTool at your discretion, you can flash the EDL of the original system if you prefer.
I'm not an expert but this has solved my problem.
To unlock the bootloader, if the unlocking with EDLTool does not go well (it happened to me just yesterday while I was installing a Rom on another Axon 7), you can use Axon7ToolKit 1.2.1, it always worked well for me.
I hope it can help :fingers-crossed:.

Hi, just want to let here my solution for the same problem, it may help others.
I tried to flash A2017G_B10_NOUGAT_FULL_EDL and A2017G_B02_OREO_FULL_EDL but always getting the Can't mount /cache/recovery/last_locale error, phone completely bricked.
So I flashed A2017_B13_FULL_EDL_UNBRICK_DFU using MiFlash through EDL, you can find this here: https://forum.xda-developers.com/axon-7/how-to/a2017-4th-category-brick-repair-manual-t3585898 (if your EDL mode works fine there is no need to disassemble the phone as shown in that tutorial)
Now the phone is completely working, recovery and system, but everything in chinese.
Then I flashed A2017G_B02_OREO_FULL_EDL using MiFlash through EDL, and now everything is working and in english
Thanks a lot for the tip! A2017_B13_FULL_EDL_UNBRICK_DFU did the trick and unbrick the phone.
What i did:
1. used MiFlash to flash A2017_B13_FULL_EDL_UNBRICK_DFU
2. after that A2017G_B03_OREO_FULL_EDL
3. reboot to recovery and performed factory reset
First time I did not perform the factory reset and got stuck on the boot picture without the reset function (power button did not work). Drained the battery and performed factory reset and got the phone working again.
update:
Phone is not stable on B03, some apps crashing from time to time for no apparent reason and also soft reboots happening randomly.
Now I got stuck on the Axon boot screen again after rebooting the phone manually and waiting for the battery to drain ...
i did not install or perform any custom action to the system, just regular use and apps, but it is still acting up badly.
I was planning to use this phone as a secondary handset because it is actually a very nice piece of hardware but now i am starting to have second thoughts about that.

Stuck at 'bootloader unlocked' screen

My A2017G did an OTA update on its own yesterday and after that it would only display the 'bootloader unlocked' warning and go straight to DFU mode. I managed to get into EDL mode and Windows also now recognises the phone as 9008. Is there any way that I could backup data before reflashing? The key combinations work normally and I can reboot into any mode

Did you have TWRP or anything else installed?
If you don't have TWRP, install it via EDL with EDL Tool, then enter it and get stuff out via usb. You were most probably encrypted, in that case I honestly don't recall which TWRP handled stock encryption, but I guess the official one on twrp.me (axon7) does.
any reason you're still on stock, though? Friendly advice, take a hard look at the new Pie device-specific ROMs

I tried flashing various versions of TWRP using the EDL tool and it always showed a success message at the end, but when I booted to recovery via the bootloader menu, it just went to DFU mode instead.
Also, i tried custom roms before but i switched back to stock for the camera quality.

[Help] Bootloop after updating, usb debugging not enabled.

Using the miflash tool I flashed stock firmware (some version of android 8) after previously having a custom ROM installed. Everything worked fine until I rebooted after updating to the latest version using OTA.
My phone never got past the android one screen where it would freeze part way through, and after removing my sim card I could get to the pin unlock screen before the lock screen but after inputting the correct pin it would reboot and ask me for it again and again. I can get into fastboot fine but since usb debugging wasn't enabled and my bootloader is locked I can't reflash.
Booting into recovery also only brings me to a screen where the android mascot has a red triangle with an exclamation mark and a message saying "No command", so I can't factory reset.
Is there anything I can do to unlock the bootloader in this state or factory reset? (all flash tools and fastbooting into TWRP require the bootloader to be unlocked which in turn requires usb debugging to be activated)
Thanks for your time.
Update: I messed around with stuff on the cli based tissot tool and used option 2 to boot me into TWRP. It didn't do that but brought me into android where a system process kept repeatedly closing until a random factory reset happened.
I then got into normal android for a bit before I had to reboot (did remember to unlock the bootloader this time). I can now install twrp fine but every time I install the stock rom using miflash or try to install resurrection remix through twrp I get the same bootloop issue.
For some reason also my internal storage is completely empty no matter what i do so i need to sideload roms via sd card. And sometimes twrp gives me the error "failed to mount /system"
Trying the latest version of LineageOS next.
Update 2: if you have the same issue I had, the only working fix I've found is this restore point for twrp. Have not tried to update yet in case it breaks again but will make a final update with how that goes.

THIS PROBLEM IS VERY ANNOYING!! (The reason is because i didn't backup EFS before i flash Custom ROM) And I would like to share how to RESOLVE it. **your phone must be Unlocked Bootloader. Search Google how to do it. (Quick tip: in Fastboot...
