I have noticed that FTM mode isn't always accessible (VolDown+Power for about 5 seconds). And I think it is dependent on which ROM and bootstack is installed. I can't seem to access it if I'm running a ROM like AOSP Extended, LineageOS, Resurrection Remix, or similar. But it always seems to be accessible if I am running the stock ROM.
FTM itself isn't important, except that it provides a restricted ADB shell that can be used to reboot into other modes, like EDL. Let's say you get into a situation where recovery, boot, and system are inaccessible. And you can't access EDL either. This happened to me recently and I had to send the phone back to ZTE. Back then, FTM would have been very useful for getting into EDL, rather than being stuck in DFU.
Can some people running various ROMs (stock/stock-based or custom) test access to FTM and say whether you can get into it or not? I don't particularly care whether it is Marshmallow, Nougat, Oreo, which model of the A7 you have, etc. And it is a quick test that won't inconvenience anyone. Please state which ROM and bootstack you were running at the time of the test, and which A7 variant. I'm just curious, is all. To prevent bricking the phone, access to as many modes as possible are important, the 2 most important being EDL and TWRP.
I think I remember reading on one of ZTE's websites says that FTM is "field test mode", and is a software-based mode rather than hardware. Probably used for running various tests. And it seems to be dependent on the presence of certain files in the system partition (located at /system/vendor/etc), which aren't present on non-stock custom ROMs. I have noticed that this mode is also not accessible if the system partition is empty (wiped/formatted), even if on a stock ROM with the stock bootstack.
Thanks!

FTM is factory testing mode (says so right in the mode itself) and won't work if you have a DFU brick, even on stock. That's the whole point of DFU unbricking. One guy said that he could save his phone by running down the battery entirely then using the combination to enter ftm. I've been telling bricked people to replicate this for quite some time, nobody could.
@Choose an username...: Thanks for the clarification, but the exact meaning of FTM is really just semantics if you ask me. The important thing is that it allows rebooting into EDL in the event that other boot modes are inaccessible. I have heard that EDL can't be accessed on the A2017G via the hardware button combo, so 'adb reboot edl' from FTM is the only way if you are locked out of Android. I'll take your word that FTM won't work if you are DFU bricked, I couldn't access it either.
The whole point of this topic is to ask people who are *not bricked* if they can access FTM, as a means of getting elsewhere.

You can acces EDL with button combo onthe G variant.Also you can boot in EDL if FTM works

Some time ago I had a serious problem by reverting back to A2017G stock B10 to achieve B12. I did something wrong in a hurry and afaik DFU bricked the phone.
There was only the QUSB when trying the button EDL combo and the hardwareID under QUSB was : (there was even a text 'DFU...'
Code:
USB\VID_19D2&PID_0112&REV_0000
USB\VID_19D2&PID_0112
My friend djkuz acknowlegded it was a DFU because values should look like :
Code:
USB\VID_05C6&PID_9008&REV_0000
USB\VID_05C6&PID_9008
But the good part was - and i dont know why - i COULD enter FTM with the 2 button combo.
But only the drivers were not installed the right way. There was 'adb interface' and 'android' with an exclamation sign.
I just reflashed drivers : https://androidfilehost.com/?fid=745425885120753806
And I could adb reboot EDL.
Im not an expert on this but I can only say that the symptons were DFU but there was that way to unbrick through FTM.
Nice info, but the real point of this thread is to establish whether FTM is only available if you are running a stock/stock-based ROM. Because when I have tried to access FTM on AOSP/Lineage/CM-based ROMs (or similar), I have never been able to access FTM. That's why I'm specifically asking whether others can test too, regardless of their specific configuration.

I think I fucced up pretty badly this time...
I was on LOS, wanted to get back to stock, for some reason wiped and rebooted...
Infamous DFU mode. I can't get to FTM (tried power + vol down and it only turns on, scrolls a little and turns off), and I wasn't able to use axon7tool using zadig. No recovery at all, no fastboot, nothing...
I've installed QDLoader 9008 drivers and MiFlash actually recognizes the... thing. Can anyone tell me if this is worth trying/what I have to do? Thanks
P.S I have no way of returning it to ZTE
Edit: The miflash thing didn't work as expected, can't find programmer file
Look like you kill yourseft this time.
You have to enter EDL with any cost, or at less FTM - let batttery drain up and try again.
Otherwise, people say somethings about a DIY EDL cable, but I not really sure

I've found this QPST thing from Qualcomm, also heard that the only thing missing is the programmer which is not released. It detects my device, reports it is a Sahara Memory Dump, and that's pretty much that. I hope that people is actually looking into this
Also I noticd that in the first seconds when it is seemingly installing, it says it is a Sahara Download. Does that help?
I also wanted to know, is there a main thread for this sort of thing? I've seen @tenfar 's thread but there is nothing to do on A2017G's
https://forum.xda-developers.com/axon-7/how-to/a2017-4th-category-brick-repair-manual-t3585898
I know you're already active in this thread, but I don't know if you understand it in depth. You must open your device to enter into edl mode. In edl you can flash twrp and are back in business. So your only way to enter edl is to open your brick as described.
Thank you, however i wanna be extra cautious here. When I have to connect the test point to ground, do I connect it with the SIM slot? What is valid as ground?
If MiFlash recognizes it you should be able to flash a stock Rom. The I have the A2017U so I could be wrong

Hey guys, I have a A2017 axon 7, and I tried to upgrade from Marshmalow to nougat by flashing the B04 update from TWRP. I have now the factory recovery mode, and when I try to go in fastboot, it tries to launch the bootloader( which just tells me that my device software cannot be checked for corruption and that I need to lock my bootloader). When I try to boot normally it stays on the same "bootloader screen" and tells me to press the start button which makes the phone display the linux logo.... I'm a bit lost, I'm on ArchLinux could you pls help me ?
Thx !

Well, you should use MiFlash and install the stock system through EDL. The problem is that MiFlash is for Windows x64. if you could get a win10 x64 pc, you could fix it in a minute.
Or get to the recovery if you can, and flash Nougat again but via an SD card. But maybe you won't be able to get to the recovery mode

When I press any combination it always turn on for 1 sec and then the screen turns off again but it still GOT recognized as QUSB Bulk. After I installed MiFlash the device is recognized as QDLOADER 9008. I didn't flash anything and I don't kno how to unbrick my device now .
I use the A2017G model btw.

How did you relock the bootloader? If you used a guide, you should have found a warning, and if you used axon7toolkit a message should've popped up.
You messed up. Real bad. You are probably on DFU mode, and the only ways to get out of there are:
-discharge the battery completely and try to enter FTM mode (i think you have to do that while it is connected to a PC), I think it was with volume down + power. this method works for very few people. If you enter ftm mode, issue 'adb reboot edl' and use MiFlash right away with a FULL_EDL package
-use the 4th category brick repair manual (disassemble the phone, short some pins)

it's not necessarily like that. DFU mode is just a mode in which the phone can be. Sometimes Windows just installs the QDLoader driver even though it's not EDL. and if you tried miflash and it didn't work, then it's most probably that.
There's a way to check. If you go to Properties, there should be a number that identifies the mode. if you google it and 'dfu interface' appears, then you are dfu-bricked
But if you locked the bootloader without being fully stock then it's most probably dfu bricked anyways
Again, how did you lock the bootloader?
I don't actually know if I really locked the bottloader.
So, I had unlocked bootloader and twrp. I just bootet into the bootloader, typed "fastboot oem lock" in adb and it said OK on the PC.
But on the phone it never asked me if I want to lock it or anything. And I never said MiFlash isn't working. It recognizes my phone but i judt didn't TRY to flash anything because I didn't want to make the situation even worse perhaps

Lol it doesn't ask you if you want to lock it, that's the point with bootloader mode. there's no system, no UI, and you make stuff via commands.
This is why you shouldn't even attempt this kind of stuff without knowing how it works. At least if you had used axon7toolkit, it would've told you not to.
Find a FULL_EDL package for your model. If you have an A2017, simply use this one:
https://androidfilehost.com/?fid=817550096634790942
or
https://mega.nz/#!JqwEUDCa!lW3NDaBNbmMxhtw6XajspHBJaaEmLC8uNvMZS5ww0EQ
(they are the same file)
Unzip it, leave the folder somewhere handy, put the phone in what you believe is EDL, open MiFlash and select the folder, and flash

Okay let me tell you this real straight. I have done this. I have the G packages, I just thought you were the op for some reason. Look at the back of the phone and confirm whether you have an A2017G or an A2017 just in case, or you might mess up even more, as hard as that can be.
at any rate, your fears are all dumbfounded, because in the situation that you are in, you have 3 options:
a) disregard all the help that i'm trying to give you, even though I have already done the process; and keep your brick on a shelf.
b) search on google or xda yourself, then do the process, without bothering here with your lack of trust
c) follow my advice and do the damn process
Whichever option you choose, I'm gonna leave the package here:

Again, I HAVE FOLLOWED THE 4TH CATEGORY BRICK REPAIR GUIDE AND FIXED MY G. I flashed stuff through EDL at least 10 times. And there wouldn't be a bunch of EDL packages for the G if they had a 100% chance of bricking your phone
So. If you decide to do this, turn your phone off. connect the USB cable to the PC but not the phone. Hold both volume buttons (but not the power button) and insert the USB cable at the same time. Then fire up MiFlash and try to flash the file (you have to unzip the folder, then select the folder on miflash, then flash. Here 2 things may happen:
a) it flashes and you can just go bother someone else
b) it doesn't and you have to follow the 4th category brick repair guide
Simple as that. if it fails, you might want to check if the 'Qualcomm HS-USB QDLoader 9008' is actually EDL mode or DFU mode, so you can do that by going to properties and checking some device identifier number on google (haven't done that, i just read that it can be done somewhere here).

THANKS SO MUCH , you saved my ass, it flashed without a problem and sorry for bothering you. Bootloader is locked now and it works fine. Thanks again!
Not sure how to title this forum post, but this is the best I got. Forgive my ignorance and lack of knowledge on these topics.
I was trying to root my Axon 7 mini. After some searching to find out how to unlock the bootloader (like needing JDK, older Android SDK version to run android.bat, etc.), I finally got it to work. Ran Recovery to "apply update from SD Card" (can not remember the file right now) and was then ready to load TWRP Recovery. When I rebooted to the recovery TWRP image, it told me something failed and the phone had to be factory reset. I took my SD card out in fear of my data being deleted and "accidentally" clicked the power button. It then reloaded with a password prompt where I typed some random password (1234 because I never set a pin password nor knew what to do here), clicked submit, and then gave me some error; now my phone doesn't work.
The Problem:
- I can enter bootloader, sometimes, but can only run fastboot commands; adb device does not detect phone so can't run adb commands (always says the server is old or something and reloads daemon successfully but never finds my device regardless). Also, I don't think I can get it to run in EDL mode; MiFlash gives out errors too when trying to flash recovery images.
- Recovery mode doesn't appear or work; not sure if the MiFavor command prompts on the phone is recovery or not, but it's safe to say this no longer appears. This is also where I believe the phone bootloops. I can get the fastboot commands to flash a TWRP recovery, but it never actually enters the TWRP dashboard.
- Can not turn off the phone... I think. None of the command options that appear on-phone shut it off; however, when the screen does stay black, I'm not sure if it's in EDL mode or plainly off.
- Device Manager shows the phone as different stuff (namely Kedacom USB Device and Portable Devices/MTB USB Device). Sometimes Qualcomm appears, but it depends. More often than not, when my device does appear, there's either an error code (like Code 10, Code 43) and/or the device is grayed out.
Conclusion:
I just want to get my phone to work normally again, if possible. Currently, I locked the oem to see if fastboot commands could still work and now I'm stuck at the ZTE logo, so can't try to unlock it right now. What are the proper tools, drivers, programs, etc I need to get this phone back to normal? I've scoured the web and these forums for 2 days now with no luck and lots of either missing info or obscure info.
I bought this at Best Buy, so I'm assuming it's US Axon7 Mini version in terms of drivers (not sure if the box specifies any info that could be useful here).
Un-brick Axon 7 Mini
Dear all,
I experienced the same issue with my phone after I tried to flash it with custom ROMs and recovery.
I thought I lost it as I was not able to enter adb mode (not recognized on the PC) or even not able to enter EDL mode with the button combination so not able to do anything with it.
Only watch it boot and display the ZTE logo.
After some research, here is what I had to do to get it recovered.
First thing you need to get is an EDL cable.
I let you search on your favorite site. Mine was a Generic eDL Deep Flash Qualcomm 9008 Cable 2 in 1 for Z3 X/Octopus.
Until you receive it, make sure you have the latest Qualcomm drivers installed on your PC.
You can find it easily.
Then, connect your phone and your PC with the EDL cable.
Press the button on your EDL cable (there should be one) for a few seconds and keep it pressed.
Then, press the power button and keep it pressed for at least 20 seconds.
At this stage, you should have both buttons pressed and after some time, you should feel the phone rebooting.
After 20 seconds, release the power button.
Then, after 10 other seconds, release the EDL cable button.
At this stage, your phone screen should stay black and your phone should appear in the device manager as Qualcomm USBHUB (or somehting similar)
You are in EDL mode and should be able to perform a recovery flashing using tuliptool.
Then I followed the steps I found here:
https://forum.xda-developers.com/axon-7-mini/how-to/updating-uk-version-zte-axon-7-mini-to-t3717933
If you are still stuck, pm me.
Be patient, all will be fine,

I had a feeling an EDL cable was my only option left given everything I've looked up and the multiple methods I've tried. Wanted to avoid spending money on one but doesn't look like I have a choice given the circumstances - oh well. Regardless, thank you for the response and advice. Have to wait a while, though, to get the cable and test to see if this works.
If anyone else ever ends up in the same royally screwed situation as me, getting an EDL cable - or DIY one if you wanna be cheap and are confident enough to do so - is probably your saving grace.

K, I can get tuliptool to work and run command, but i keep getting a "Failed: Unkown Error" response everytime i run a command. Can't unlock my bootloader, nor write a recovery disk due to this error. does anyone have any idea why this happens?
So, basically I will make this short as possible
Due to some problems I had to sell my G6 Plus (Brazilian -8 model) but it was on a custom rom, and did the most dumb thing that I could do: Reflashing pure stock and locking it, I've used the LMSA tool then relocked in Fastboot, the thing is some files were corrupt and when locked, it doesn't boot up anymore, as i still had hope for it, I tried to LSMA again, but it doesnt recognize anymore, as the lock flag is now "Flashing_Locked", flashing manually via Fastboot gives a error related to the lock flag (also LSMA resets the device, so using my unlock key asks to enable OEM Unlock at settings, a impossible thing when OS is broken) , then searched for some solutions, first it was booting a Boot.img file from the last stock, which was the flashed one, it bootloops, then tried something on the recovery that works, but is the stock one and pretty limited, so the logical thing to do is flashing a OTA file, but only works for old versions that requires one version before the target one, so its a no go. The last thing i tried to do is booting TWRP, but it gets stuck on a red warning that indicates that system is corrupt. Then the last hope was EDL Mode, and thats the point where i want to go, i've bought a EDL Cable that's basically a green and black wire thing used on most Qualcomm based Redmi/Xiaomi devices, but it automatically boots to fastboot, so I need help to get EDL Test Points for this device, im with access to the board, i just need the right Pads to short-circuit it and blankflash it, so i can finally get it to work like normal again.
Schematics (for people who understands): https://androidfilehost.com/?fid=4349826312261726244
Any help is important, I'm sorry for some typos, english isnt my main language considering i didnt use translate
and please don't come with instructions like "have you tried LSMA?, try booting up the device and select oem unlock" because its clear that it doesnt work.
So im gonna start off by saying that im just some dumb 18 year old and have never actually posted to ask for help, only reading other peoples situations to try to figure out my own.
but introductions aside im just gonna jump in to everything wrong with my oneplus 8 pro (global)
I was on the OOS 12 beta for a while, ive been way too lazy to change it back since ive been occupied by other stuff.
I was using magisk and decided to do some fun shenanigans with it.
I get into bootloop after flying to close to the sun with modules - a common occurrence.
so I try to switch to a custom rom since I was gonna reset anyway.
I download CR droid's recovery and main rom, went into fastboot and flashed the recovery.
I notced that whenever my phone was plugged into the computer, the options would rapidly switch on fastboot's end
when I tried to boot to recovery after flashing, it would only return to fastboot
confused I thought that maybe the recovery was bad and try another rom, no dice
i submit defeat and go to msm tool to fix the issues
I get that "Sahara communication failed" error so I hold down the volume up + power for 13 seconds before trying again.
it flashed smoothly
after getting sad at all the bloatware that was on oxygen OS after a full reset, I get the motivation to try using a custom rom again, this time using a different rom.
same weird fastboot behavior
I was unable to go into recovery
I then tried downloading stock firmware to flash it manually
fixed nothing
I delete the boot and recovery partitions and flash them again, still no dice
I even make a partion called fart, before remembering that I do not know the partition structure of android so i Ctrl+C out before it makes the partition
I go back to msm tool again in shame
"Unknown Target Device"
I reinstalled drivers
switched computers and cables
changed the source of my drivers
nothing fixed this error
and every time I would try to do anything it would go directly back to fastboot.
I try reflashing partitions in this broken fastboot mode and it would only flash if I unplugged, selected reboot bootloader, and plugged it back in
I would then try to fastboot boot into TWRP or other recoveries i downloaded
they would shut off the phone
I remember a/b partitions exist so I switch over between them and try to flash stock OOS again
after more fiddling and nothing working, I noticed some more weird traits of fastboot
twrp did boot directly after switching my main slot, not specific which one just if the slot was changed.
the "this device has an unlooked bootloader" message did not appear
only on slot a would the oneplus logo show up on boot
again every option I would click would take me right back to fastboot.
I wait a day for the phone to die so I could use EDL that way, at this point the twrp method randomly stopped working so I couldn't go into edl that way.
"Unknown Target Device Param Preload"
and like I know Param Preload is a common error but nowhere could I find information on the unknown target device part.
the phone still vibrates if I hold the power and vol+
it just vibrates in a loop as if it keeps rebooting, probably fastboot just selecting the start key over and over when I hold it down.
vol- and power do nothing, and did nothing for the entirety of this story.
is there any chance of saving my poor instantnoodle professional?
## edit for people googling this
the problem I was having was that I didn't set the "target" button on the MSM tool correctly, so make sure its set to O2 or your appropriate reigon
1. Stop fastboot flashing with A12 or if you are on A12.
2. Read this: https://forum.xda-developers.com/t/...ro-8t-9r-with-oxygenos-12-coloros-12.4426167/
3. Rescue your phone using this: https://forum.xda-developers.com/t/...l-to-restore-your-device-to-oxygenos.4084953/
4. Stay on OOS11 (Most custom roms INCLUDING A12 custom roms require OOS11 anyway.)
5. There is not much bloat on a OOS11 rom IMO but you can always use a debloater.

Maybe I should clear on what i have tried. since I have read both articles before I made this post (i scanned through them again once you sent them tho)
Ive tried...
The unbricking Msm qualcomm 9008 tool
ive used it a ton in the past
ive switched copmputers, cables, and the qualcomm driver, as well as reset the phone several times
also yeah im not touching oos12 after this with a 9 foot pole, but is there a way of knowing wether I can save it or if its too late and the motherboard has been fried.

Okay i guess this is another situation here. You are not bricked like the other peoplke as far as i can see because there devices are completly bricked. No connection to pc or vibrating at all.
Since you used MSM tool before it should work IMO. Does your pc regonize the phone? Did you tried to switch usb ports? Did you tried other versions of msm tool(eu, older verions, etc)?
Please make sure to follow all MSM instructions closely.

after a week of fiddling I DID figure out the issue
unsupported Target unknown was refering to the fact that I had the MSM tool set to Target mode, which I assume tries to set the region according to what the current device has. After selecting that to O2 for the global models, the flash worked fine. I ended up coming across some C stock of a google pixel 3a and will try messing with that so I dont have to go a while without calls or texts. Glad to know I learned some bit of responsibility from this excursion.
