bought this phone used and I don't think it was rooted but never checked, confirmed. Last night it turned off and will not turn on anymore..
Tried the pwr button for several minutes and no change. Plugged it in with several different cables and no change.
Any other suggestions or options? USB to computer detects something but says it can't install the driver.
Any ideas?

Can you enter to the bootloader menu? Maybe you can enter recovery and wipe the cache and dalvik

negative, either the phone is totally dead or the screen is dead but NOTHING happens when pwr is pressed
here is what I have tried:
1. Press and hold PWR button for over 3minutes
- Plugged in and unplugged into ac - no change
2. Press and hold volume DOWN + Pwr for over 3minutes
- Plugged in and unplugged into ac - no change
3. Plugged into different a/c power outlets with 2 different chargers - no change
NOT sure what else to try or do?
Funny thing is if ya plug into a computer it does indeed detect "something'
However it says it can't load the USB drivers something about QU_***
Open to any ideas and suggestions.. WHILE I would love to get the phone working whats more high priority for me now is the 20gb's of pics that apparently did NOT back up.

Funny thing is- that "something" is the solution to your problem. Capture the error message completely and search the 6P forums for that. Several threads on the "something" issue.

Several threads with no solution. I went through the same "something" . Can't be fixed

fixed that issue, aka QHSUSB_BULK is now working properly according to Device Manager.. but Nexus 6P is not detected, and doesn't even show up in Disk Management either.
Any other ideas?
please advise..

If you found the right EDL_9008 thread, there is Qualcomm software to download for your PC. If your phone is in the right downloader mode you can use the PC software with a special recovery.img. I don't know anything about it, just read through the threads long ago. It's a mixed bag with some success stories, some not. Keep looking though, I think you are on the right track. The original poster was "Tenfar" if I recall correctly. Good luck.
Try cleaning out the charging port.
Hi there,
I think we are in the same/similar boat. My phone shut off while using it (screen froze, then went black) and seems to have bricked itself. I *am* able to get mine to turn on, but only about once per day after it has been left plugged in for a few hours (although there is no indication it is charging while plugged in - never gets warm, no lights, etc.) I can get into recovery if I am lucky (usually get to the android bot laying on its back, then PWR+VOLUP just causes the phone to shut off instead of actually getting into recovery menu.) I've been able to clear cache/factory wipe from recovery menu with no luck. I never did unlock the bootloader so I am unable to use fastboot to do anything. I tried to flash a few OTA (full and incremental) images using adb when I am able to get into recovery, but they always failed in one way or another.
I've been trying the methods described in the 'tenfar' threads - using the xiaomi flasher and QPST tools. The xiaomi tool always fails for me. I have been able to get the QFIL tool to successfully 'download' about 3 times now, with tenfar's recovery images. However, after the success message, the phone doesn't do anything (I read in other threads it should reboot itself) - and after unplugging, the behavior of the device seems to be the same - just stuck and won't turn on at all.
Right now I think I am stuck in 'EDL' mode where the only evidence that the device isn't completely dead is that it shows up in device manager as 'Qualcomm HS-USB QDLoader 9008 (COM3)', and the factory imager tools do recognize it.
It *seems* like the only way forward is to somehow get one of these factory tools to flash the right set of files onto the device - I've tried a few now with no luck. I even tried extracting the relevant *.img files out of the google factory image download and replacing tenfar's image files with them. I was able to load those onto the device with QFIL. This morning my attempt at turning on the device has me stuck on the white google logo, which is new behavior for me - usually it shows the logo for ~5-10 seconds then the device powers off. I've left it on for a while stuck on the white google image, but I'm not sure if I'm doing anything useful here.
Here are my reference threads:
tenfar's 'debrick' thread
QFIL thread
If anyone has any crazy ideas, I am open to try them. Thank you.
Maybe disable big cores?

I have the 100% same issue. Screen froze,then went black and now its stuck in EDL mode. I need my data. Recovery access or anything else would be fine/enough for me. I have had LineageOS and TWRP on the device. With TWRP i can access my data.
How have you got your device on? Mine dont start once a day or so. Its always in EDL mode ( 9008 ).

Sorry bud - I never was able to get any further than when I posted this. I eventually gave up, got a full out of warranty refund through my CC after the manufacturer wouldn't help me at all, and upgraded to a Pixel XL. I still do have the device, I should try to boot it up again . I didn't have any data concerns on my device so I was able to give up... good luck!
Hi,
Messed up badly Furious that ZTE made the phone incompatible with Daydream, decided to root the device. Tried various ROMs, but could never get the modem to work in the UK. Eventually tried to reinstall Chinese stock ROM and, to my surprise, the modem still didn't work. Attempted to restore the modem files from TWRP backup and bricked the phone completely. Can only boot into Chinese recovery where only ADB sideload enables the phone to be seen by Windows as Android ADB Interface. EDL mode cannot be seen and Axon7toolkit cannot see the phone even in ADB sideload mode. Attempts to update software result in this message: Package expects build fingerprint of ZTE/P996A03/ailsa_ii:6.0.1/MMB29M/20161027.021856:user/release-keys or ZTE/P996A03/ailsa_ii:7.1.1/NMF26F/20170224.135053:user/release-keys ; this device has ZTE/P996A03/ailsa_ii:7.1.1/NMF26V/20170912.013327:user/release-keys. Most likely, updates won't work anyway, because when the phone was running, updates resulted in a mismatch. Any feedback would be much appreciated.

You messed up real bad. I assume you forgot to flash the modem files when you flashed the custom ROMs?
EDL mode cannot be seen? What do you mean by that? Keep the Device Manager open, phone disconnected; then hold both volume buttons, wait 5 seconds, connect the USB cable while you are holding them, and wait 3 seconds more before releasing them. The device manager should refresh.
The phone should appear under Ports (COM & LPT) or under USB devices as QUSB_BULK. If it is under USB devices you have to right click on it, Uninstall -> Delete driver software. After that hold all 3 buttons for a long time (both volume buttons and power) and device manager should refresh itself. It should install the Qualcomm driver then. If the driver is ZTE handset diagnostic interface, you'll have to disassemble the phone

Thanks. The phone is listed as ZTE Handset Diagnostic Interface(DFU) (COM10) in Ports. It is listed as Unknown USB Device in USB Controllers and following the procedure you described doesn't install the Qualcomm driver. I take it, then, that an engineer would have to disassemble the phone.

Or you. Follow the 4th category brick repair manual. I'm just rewriting it but it'll take time
Where are you getting adb sideload from?

Well, with your help I may snatch victory from the jaws of defeat. I'll ask one of the local engineers to dismantle the phone according to your guide and we'll see what we can do. The adb sideload screen is in this photo.

You still have one other option though. May save you.
Do you have an SD card? If not, get at least a 4 GB one (or one with 3gb free), download an official A2017 update package, unzip it and put the update.zip in the sd card. (If you get a bunch of folders instead of a file called update.zip just take the original zip and put it in the SD).
after that, put it in the sd card and select the option that says 'sd'.
It may work. Right now it's your best shot at not taking it apart

That's forbidden. When I've tried to update from the SD card using that option, I get a message saying I don't have permission to update from the SD card. I will, however, try again because you've mentioned some things that are slight variations on what I've done before.

Yeah, it's possible. But I have one more idea. Can you try one other thing?
There's a way to get to EDL if you have only DFU mode, which is by getting adb (not adb sideload, just normal adb) and issuing "adb reboot edl". If you can get adb (i think you may have adb from the main recovery screen) then you can get to EDL and flash stuff with MiFlash. Try to issue 'adb reboot edl' when you are on the main screen of the recovery mode.
The other way, which might work on your state, is turning the phone off and holding volume down + power. It might open FTM mode (it's a white rectangle in the middle of the screen with the words FTM written on it, can't miss it). If you get there just issue 'adb reboot edl' and flash with MiFlash

Thanks, but I've already tried it. The phone only communicates with the computer in adb sideload mode, so trying adb reboot edl results in an "error:closed" message. If not in sideload mode, adb cannot even register a device. Occasionally, I've seen a small Linux penguin in the middle of the screen and today it hung on the MiFavor logo for some time. If those are significant, I don't know how to get them back. The ZTE engineers have been very thorough. It's frustratiing because the adb sideload thing might work with the right software package, and I can clear the cache and wipe the system; but then I'm back to square one. Your suggestion about dismantling the phone sounds like the most promising path forward and I will have a go tomorrow.

So you get the 5 seconds screen? Have you tried to enter fastboot?
If I'm right, you get the Linux penguin when you hit the power button when you are on the 5 seconds screen (the 'Your device can't be checked for corruption' screen). If it appears, use a volume button to get to the options, select 'Bootloader' and try to enter Bootloader mode. It should have fastboot, being an A2017.
If you get to fastboot you can issue 'fastboot boot twrp.img' and your phone will boot into TWRP. Take Lineage, the Universal Bootloader and the A2017 modem and flash them, then format data, and you'll be good to go.

I do indeed get the 5 seconds screen, but the reason I didn't mention it is that it does nothing from what I can see. The phone "boots" after five seconds, but if I press the volume buttons to enter options, Bootloader is not one of them. The Fastboot option just makes the phone reboot and the Recovery option sends me to the screen in the photo upthread. Like I say, they've been very thorough.

Curioser and curioser. I went through the steps to short circuit the test point on the motherboard and MiFlash successfully flashed the Unbrick ROM which you advised. Obviously, the Qualcomm drivers were recognised e.t.c. The state of the phone now is that it is caught in a boot loop. It shows the ZTE screen and the 5-second screen. Going into recovery on the 5-second screen causes the ZTE logo to appear again, then the battery icon keeps showing, switching off and showing again. The Fastboot mode on the 5-second screen now takes me to the Fastboot screen, but entering recovery causes the same battery loop. Did I make a mistake reassembling the phone perhaps? Should I try to flash a different ROM from the test point?

So now you have fastboot? Put the TWRP-3.2.1-0.img on the adb folder, then open CMD, navigate to that folder, write 'fastboot boot TW" and press Tab, the filename should appear, if it does hit Enter
If you get to TWRP don't turn the phone off, and flash the universal bootloader, Lineage, the A2017 modem, and Magisk 15.2

Sorry, I didn't make that clear. The 5-second screen directs me to Fastboot, but there are only four options there: Start (doesn't work, obviously), Restart Bootloader (brings you back to the same place), Shut down and Recovery (goes to battery icon). Don't know what went wrong--maybe a connection got damaged when the phone was dismantled--but I discover I can't repeat the short circuiting thing and, even though the phone is seen on the system as Qualcomm 90.., MiFlash cannot flash anything different. I despair. I'll send the phone for recycling. Making the Axon 7 incompatible with Daydream was the last straw. I very much appreciate your help just the same.

No, when you are on the screen with the 4 options you have Fastboot. That is the bootloader mode. Get there and issue 'fastboot devices' and you'll see that you got fastboot from there.
Don't repeat the 4th category manual, just turn the phone off and hold volume up and down, then connect the USB. If it appears as Qualcomm HS-USB QDLoader 9008 you're in EDL.
What's the name of the package that you flashed?

You star! I've followed your advice and now it is exactly the phone I was looking for. (I had made a mistake and forgotten to reconnect something in the internals, but the ROM worked just fine once that was sorted and I've flashed all the things you recommended.) Your name will be sung down the ages in my household, Choose an username. Many thanks
Hey guys,
Guess today it was my turn ****ing up.
I apparently have completely bricked my Axon 7 after trying to go from LOS 15.1 to stock oreo beta. The only thing I seem to be able to boot to is DFU mode and for some reason, if I press the Power button + Vol Down I will get stuck on the ZTE Logo and my PC will detect my phone through the ADB interface but every time I try doing something it says my device is unauthorized. Is there any way I can authorize the device whilst being completely bricked?
The only other thing I get is the unlocked bootloader warning screen. If I don't press anything the phone will be stuck there, if I select recovery the phone will simply shut down and anything else will result in a reboot. I have also tried a deep flash cable that that only results on the phone being stuck at the unlocked bootloader screen.
I cannot access the bootloader,
I cannot access EDL mode
I can access ADB, but device shows as unauthorized.
I can access DFU mode.
Any suggestions would be appreciated. I have looked at the Hard brick guide that involves taking the phone apart but that's not something I really want to do.
Thanks in advance.
Edit: My phone gets detected by MiFlash but every time I try flashing I get a cannot receive hello packet and object reference not set to an instance of an object.
ZTE axon 7 EDL tool detects it in ADB mode but says ERROR! NO ANSWER FROM PHONE!. Possibly since its not authorized with ADB.
Ouh....DFU? I think this thing is totally bricked.
I can access my phone in ADB. If only I could make it reboot to edl or something like that through ADB even though my device shows as unauthorized. That is the only problem why this thing is completely messed up.. ADB works but I can't do anything with it because my phone shows unauthorized. Does anyone know if there's a workround or a bypass for that?

Hi Victor !
Like we discussed before there is nothing much left as to use the DFU unbrick-disassemble guide or buy something like this to be sure you tried everything.
Good Luck mate !

Thank you for your help . It's a risk you take when flashing phones.
Can you get custom recovery in it some recovery allow you to get in to EDM from there you can flash stock rom with Mi flash tool.......try to push both volume buttons at the same time don't touch the power button this might get you in to EDM.

Nothing, you'll have to use my guide for that (the one that raystef linked). Otherwise try entering FTM mode (Power and Vol-) but it's surely not gonna work. If it does, you'll see a screen with a square that says "FTM", and you'll be able to do " adb reboot edl" and flash stuff from there.
Unbricking by disassembing the phone is the most reliable method; an EDL cable just might save you the hassle but it's not guaranteed to work; some phones won't accept it for some reason. In this case just follow the guide unless you want to try your luck with an EDL cable

Nothing, you'll have to use my guide for that (the one that raystef linked). Otherwise try entering FTM mode (Power and Vol-) but it's surely not gonna work. If it does, you'll see a screen with a square that says "FTM", and you'll be able to do " adb reboot edl" and flash stuff from there.

Hello. Thank you for your advices, it is as I feared.
I have however already bought another Axon 7 which I'm using at the moment, and I have plans for mine since it was only bought new about 8 months ago and I believe I could get a replacement for a fee even if its bricked to fault of my own. So I will try that since I'm not in a rush.
This thread can be closed.
Cheers!

In that case you can just pretend that the phone got in that state by itself, it's not too morally correct but some people here pulled it off...
twice now i have gotten an axon 7 into this state. while mine have been a2017u models, i dont know that they are different than yours in that regard.
What worked for me the first time was letting the phone completely die. Being unable to boot into anything, it was somewhat a task to actually make it die, so i kept powering it on (which merely made the red led indicator come on). i did this over and over again over the course of a day at work whenever i noticed it had powered off.
eventually, the phone had no response at all. then, i plugged it up to my laptop, and left it, convinced i had killed it. a dialogue popped up after a minute or two on the phone screen saying to charge the phone by plugging it up. i had no access to fastboot or EDL mode prior. once i got that 'plug in to charge' screen, i switched it to the wall charger, and left it to charge a bit (50-60%) from that state, then, i unplugged it again, and somehow, i managed to get edl mode to work by unplugging it and pressing all three buttons and holding them (typical edl boot).
once there, i reflashed via MiFlash an earlier build. i rolled back using MiFlash as far back as i could. in the process, i lost my imei and serial, which i have yet to successfully recover, but i did get out of DFU pergatory. the imei thing seems to be caused by going back to MM which i did on both of my IMEI-less a2017u boards, but im only guessing. my dd axon 7 is the only one of the three boards with imei and serial, so maybe MM is a bad idea. lol.
The first time i recovered from DFU, i did it inadvertently by letting the phone die and then flashing in EDL mode as well. (i left it for a few weeks as i had given up on it.) after it died completely, and i plugged ut up to the computer and had the same experience, I flashed the beta oreo build for a2017 using miflash. the screen had stopped responding. and i ended up doing a RMA. I now know the screen response thing was bc of a faulty EDL file of B15. (happened again to another of my axon, so i retraced my steps and realized it was when i flashed b15 that it died) . the fix if your screen ever stops responding, but isnt physically damaged? re-flash via EDL a different file. it may take a few tries, but eventually a build will work. for me, it was Marshmallow. I still do not know for certain, but that possibly is what killed my IMEI. but hey, it boots and the screen works.
I genuinely hope posting my idiocy in toying with axon 7s has helped someone out there.
Hello, I turned on my phone this morning as usual however was instead presented into a Factory Test Mode, has happened for the first time. I then long pressed the power button but still no luck, after trying every combination possible I gave up. I charged the phone last night at 100% and turned it off as usual. (On stock rom, Oreo 8.0 not rooted or anything. - A2017GV1.3.0B03 ) Also, don't really want to disassemble or reset my phone. Any help would be much appreiated. Thanks!

what is "long pressed"? You have to hold it for about a minute or so, did you?
If it doesn't work, FTM mode has ADB, so you should be able to hook it up to a PC and issue "adb reboot" from the terminal. If you end up in FTM again then your phone is just borked or something, you can attempt to fix it by using "adb reboot recovery" instead and reflash stuff

Thanks, adb reboot solved it! Can't thank you enough!
Same case to me on OreoB03. Power button long pressed didn't respond. I used "minimal_adb_fastboot_1.4.1_portable" and command reboot.

Same problem here.
But i do not know how to use ADB tool.
I dowloaded minimal adb fastboot tool and i have now 3 executable (adb, fastboot, MAF32) in a directory but I do not know how to use them in order to reboot my Axon 7.
I would appreciate a step by step guide, made for a very beginner.
Note also that I may not have already the device drivers on my computer.
Find cmd.exe in syistem32, run as administrator, drag adb.exe in cmd window. Write command adb reboot.
Impossible for me.
I am not even able to have the phone recognized since the drivers are not correctly installed and Zadig tools wont help.
I'm really stuck.
Would any Belgian Guys be able to help me having a computer with adb WinUSB drivers correctly installed so that we can reboot my phone with his PC with any adb tool ? Please PM me is so.
Phone is recognized as adb device (w/o driver). Just try this and write command adb reboot or reboot (i don't remember).
It is said that no devices is found.
?
Also had the same FTM problem and can confirm that power button did not work in stock Oreo.
If can't get adb reboot work, one simple way is to discharge the phone - USB type C connection is fully working in FTM mode (u can simply check that). Connect one or few (use simple usb spliter) USB devices (the best way is to connect devices, for example power bank, some bluetooth speaker, which actually suck energy etc.) to your phone in order to charge them and it will fully discharge the phone in a few hours. Then on phone turned off connect power charger, wait about 15-20 minutes to charge and turn on the phone as usual (using only power button for a few seconds).
Hello, i actually thought about this option of waiting for the battery to be discharged but did not dare to take the risk. I finally found someone that will "adb reboot" my phone tomorrow, fingers crossed.
Hi,
OK, let's hope that "adb reboot" option will succeed.
However, personally I see no risks in discharging the battery - when the phone discharges it just safely automatically turns off - no data loss, no need to reflash the ROM etc. I went through this route myself.
I think it could be another bigger risk to keep the screen on (not moving screen) for a longer time - possible burn in of screen etc. But not sure about this risk and don't want to frighten, maybe others have more knowledge on possible screen burn in issues. In my case after discharging the battery no burn in or other screen problems.
I ordered a OTG cable that should arrive tomorrow to discharge the phone if adb reboot does not work. Thank you for ur feedback.
Have you tried this tool to get to EDL and then you can use Miflash to flash back to stock https://forum.xda-developers.com/axon-7/how-to/salesmultidla2017-tool-to-unblick-dfu-t3854229

that's not remotely useful to the situation
please read up before posting lmao
Mine Axon 7 did just that, couldn't turn it off in any way, also on b03 Oreo rom. So I let it discharge completely, and just did a normal power on, and it worked again.
I think that the Oreo Rom is in an awfully bad beta Rom rushed out from a sinking mobile company, that don't give a s... about their customers.
Will never buy ZTE again.
A friend could reboot mine with adb reboot. Problem solved.
I guess adb drivers did not worked well on m'y computer.
Next thing to do : downgrade to Nougat in order to get Daydream. What a shame.

Boot in FTM,open axon7toolkit,connect phone to laptop and follow instructions in axon7toolkit.It will reboot in edl and you can flash a firmware
Hello Guys, beforehand, sorry for bad formatting and some english mistakes.
Let me explain what happened.
I was trying to unlock my Nexus 7 bootloader, but I couldn´t get to the Fastboot mode via adb, so I decided to enter fastboot mode by pressing Power + Volume Down button, but I did this while my tablet was connected to the PC, and after that, it shut down and just don´t turned on anymore. (Never got to fastboot mode)
Now when I connect to windows it only show as an AXP Device and it disconnects and connects when i hold Power button, but never starts.
Also I want to note that.
I didn´t manage to get into fastboot mode.
I didn´t manage to unlock the bootloader.
Didn´t install any Custom Rom.
The device is technically 100% stock, so I don´t expect it to be a Hard Brick, but at the same time, I tried all the button combinations and it still wont turn on.
This happened to anyone? Do you guys have any idea what it could be? Any Sollutions for this?
Thank you.
(Edit: I don´t have the Blobs.bin file in case i need to use the Nvflash.)

Take a look at this comprehensive listing of Nexus 7 button presses/interrupts. They may be of some use...
https://forum.xda-developers.com/showthread.php?p=37606945#post37606945
Hi, Gabu1405...
APX mode is never a good sign with the Nexus 7. It usually indicates that the bootloader has become corrupted, erased or overwritten (by something that is not a valid bootloader). When this occurs, the device is hardbricked and usually requires a motherboard replacement to resurrect the device, although there is a procedure called 'flatline', but this requires previously generated device unique 'blob' files, which you mention in your post.
Having said all of that though, nothing in your description should have caused the bootloader to have become 'damaged'. In order to erase, corrupt or overwrite the bootloader, your device would need to be bootloader unlocked in the first place, because a locked bootloader prohibits any unauthorised write access - bootloader locked devices can only be system 'modified' by official digitally signed updates from Google, which are flashed via the stock recovery.
Are you certain the Nexus 7 is showing as an APX device in Windows device manager?
What was the battery status/percentage when you attempted to unlock the bootloader? Maybe the tablet just needs a good charge, maybe for several hours!
You don't unlock the bootloader with ADB. Android Debug Bridge only works in fully booted Android and with the stock factory recovery. You need to use fastboot to unlock the bootloader, the command being fastboot oem unlock, whilst the device is in fastboot mode, which you boot into via the Volume Down+Power Button key press combo, as you mention in your post.
How it (may have) got into APX mode is certainly strange, because as I've said, this isn't something that normally happens spontaneously - when it happens, it's often due to people mistakenly flashing an incorrect .IMG file to the bootloader partition, causing the bootloader to be overwritten. A possible explanation is hardware failure, and that the emmc/NAND chip storage has developed a fault, and caused the bootloader to become corrupted. It's worth bearing in mind that the Nexus 7 is now seven years old, and with the best will in the world, these things don't last forever, unfortunately. Components fail and data corruptions occur.
If your Nexus 7 is truly in APX mode, for whatever reason, then I'm afraid it's likely hardbricked, and a motherboard replacement is the only realistic way of resurrecting it.
I can only suggest you try charging your Nexus 7, maybe overnight, or for several hours at least, and maybe try the button presses referenced via the link at the top of this post, and see if you can coax life back into your Nexus 7. It does happen sometimes; a seemingly dead device will suddenly spring back to life, through a combination of serendipity and hitting on doing the right things, in the right order, and at the right time
Good luck, Gabu1405...

Sorry, I expressed myself wrongly, I ran the same command as you said, it was fastboot oem unlock and it just said, "waiting for device..." then I tried fastboot oem unlock-go, also the same thing "waiting for device" so I just disconnected the tablet and restarted it and it was working pretty fine, then I connected to the PC and tried to enter fastboot mode manually, and this is when it shut down and never turned back on.
Also, my battery was at 70% at that time and yes, It's clearly on APX mode.
Well, thank you for your reply, now the only thing I got to do is recharge it and hope for the best.
Regards.

Probably not much use until, or indeed if, you can get out of APX Mode... But the 'waiting for device' message is usually an indicator of a Windows driver problem - Windows is not able to communicate with the Nexus 7.
The way you'd normally do things is by first running the command fastboot devices
This command does nothing, except to confirm you have a viable fastboot connection, by displaying your Nexus 7's unique serial number in your Windows Command/DOS box. If this serial number fails to appear, you have a driver/connectivity problem and proceeding on to fastboot oem unlock would be pointless until the driver/connectivity problem is resolved.
Anyway, I hope charging the device helps. I'm still inclined to think that your device is recoverable - it would certainly be very unusual for the bootloader to be borked when it hasn't even been unlocked yet. In the seven years I've been a Nexus 7 owner, and being active on these forums for many of those years, I haven't encountered any reports by other XDA members where a locked bootloader has simply quit working... As I say, it'd be very unusual, but I suppose not wholly impossible.

Well, charged my device for a whole day, and now I tried to do the button combinations which you sent the link, nothing happened.
I thought that my battery could be unplugged or the cable was loose or something, so I opened the tablet and it was fine.
So, I just decided to do the button combinations while plugged into my PC, and I noticed that doesn´t matter which combination I try, the tablet disconnects from the PC and instantly reconnects, but still in APX mode.
I guess it is Game Over for me, gonna recharge it again, and try again tomorrow.
Thanks again.

Hi!
I had a Nexus 7 stuck in APX mode as well. Without the blobs saved you can't do anything. I tried a lot of thigs but nothing really helped. I ended up searching for an another N7 with a broken screen but with a working motherboard online. I was lucky and find one around $15. I swapped the boards and it was good to go.
