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.)

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.

some guy successfully bricked his N1 as soon as he received it about 2 months ago. When this expensive brick reached my hand, he didn't even remember what he had done... and this brick had been through many many ppl for repair, so there is no way for me to know what exactly happened during the last 2 months...
Anyway, now it:
1. light doesn't turn on when charging(not sure yet whether it is actually charing)
2. trackball + power could gets it to fastboot screen, but none of the key is working then.
3. after single press of power button when powered off, red/green/blue/white color bar and 3 droids on the screen
so , now I cannot put it in fastboot nor recovery mode, stuck.
could there be anything I can do to rescue it?

Verify this. Enter fastboot mode (connected to usb) and then try "fastboot devices" in a command prompt. It it reports a connected device then its definitely recoverable.
The only way that a N1 get bricked (software wise) is by upgrading a wrong radio, and unfortunetly the only way to recover it (now) is by sending it to Google/HTC
more explanation
thanks i did try that...fastboot devices could not detect anything,coz it just freezes at that screen and could not enter any mode using power and voldown button.
what puzzlrs me most is that screens with multicolor bars, how on earth does that happen?

update: the light turns orange now and then when charging, and it is actually charging no matter the light is on or not. ( using my own nexus to verify that )
Did you plugged it to your PC?
I knew a guy who bought a ''flashing device'' capable of formating any chipset over USB, so he could do a clean install of the Firmware again. Perhaps you could find one of these devices over ebay

That's assuming he has the android sdk installed with the correct drivers. We don't know if the op has.
@vegetaleb: the device you mentioned is somewhat mysterious... a search on ebay with "flash device" does not give me anything related, do you have a specific name?
@C.Slater: I do have them, coz I myself own a nexus too..

Does holding power+trackball bring you to fastboot?
Yes=It's not bricked
No=Kiss it goodbye, it's bricked
Simple as that

power+trackball will bring it to fastboot screen, note just the fastboot screen, it just freezes there. All the buttons does not work, and connecting to PC using a USB cable does not show "FASTBOOT USB".
However, it could enter HBOOT with power+voldown, I noticed it searches for passdiag.zip , passdiag.nbh, etc. Could I use this builtin function to flash it? which file in this post should I use?
http://android.modaco.com/content/g...-online-kitchen-optional-root-insecure-himem/
I tried to use the first one ( http://www.romraid.com/paul/nexusone/EPE76-update-nexusone-stock-images.zip ), rename to PASSDIAG.zip , but HBOOT is still complaining about "No Image"
Perhaps it's physically damaged!
It remembers me of my boss iphone that looked perfectly normal but couldn't get a FW installed because the power part has been damaged by water(power button couldn't work at all)
Try renaming it to passimg.zip and use hboot again.

tried PASSIMG.zip , still "No Image"...
You can send it to htc for repair but the downside would be that you would never know how to deal with this kind of problem yourself...
Continue the research and keep us posted ...
i maybe wrong but i think is it case-sensitive.....meaning PASSIMG.zip would fail but passimg.zip wouldn't.....Correct me if i'm wrong please....
Case sensitive
I'm pretty sure it is case sensitive. Used to be that way with other android and HTC devices. Can't imagine it's changed.
linux is case sensitive, for sure.
i say approach from the adb/fastboot route, using usb. first, ensure that you have all the correct drivers etc for adb use (the sdk, the usb drivers, and the device specific drivers).
try ur 'adb devices' command
if adb sees it, in normal mode, you should be okay. make sure the phone has 'usb debugging' turned on in settings
Please tell me there's a solution to this..!
My N7 2013 had always been fine, and I liked stock android very much, thus saw no need to unlock the bootloader. When the 5.1 OTA came, I updated my N7 and it started crashing and restarting on its own. One day, it restarted again and got stuck at the Google screen.
Of course the first thing I did was to get the Nexus Root Toolkit, and tried flashing stock rom. Of course it didn't work since it was oem locked. When I tried to unlock the bootloader, I was prompted with the screen asking if I want to unlock and wipe all data. I selected unlock and pressed the power button. Then it froze (I left it for 8 hours, plugged in to a power outlet).
The next logical thing to do was to start recovery mode in the fastboot to do a factory reset, except it simply switched to the Google screen and was stuck there.
TL;DR
Normal startup: Stuck at google screen.
Unlock bootloader: Stuck at selection.
Recovery mode: Stuck at google screen.
I'm pretty desperate now, that's why I'm posting here. Sorry if it's the wrong category or something. I've read many articles, but it's always ONE of the THREE issues I have. They often refer to using a method that involves an area where it's affected by the other problems.
Please help me, I don't want to see $250 down the drain
Have you tried using Nexus Root Toolkit to unbrick the tablet? There is an unbrick section and one of the options says something like "Soft brick/bootloop". Try that option.

I have! I saw the option when I opened NRT, and went straight for it. Here's what I did:
Checked "soft-bricked/Bootloop" option under "flash stock + unroot"
Downloaded the correct factory image
Checked "Force flash mode" (unchecked doesn't work either)
The command box came up (please see attachment)
It kept saying that the operation failed because the bootloader was locked. When I tried to unlock the bootloader, it was stuck at the selection screen after I press the power button to select "unlock bootloader".
Note: It's stuck at "erasing cache". Left it on for 2 hours.

Hook it up to your PC, open a command line to wherever you have fastboot.exe at, plug in your device to the pc, boot your device into fastboot by hand (with device off, hold down power+volume down), once it's in fastboot mode, do a: fastboot devices, what comes up?

From that point, do a: fastboot oem unlock (it will wipe the entire device (i.e. user data), if it works)
Then look at the tablet and you should see a confirmation screen, do you? If so follow it and wait some time, took mine about 12 minutes IIRC, but mine was a nexus 7 2013 not a 2012, so YMMV.
If nothing happens post a screenshot of errors, etc from cmd prompt.

How long it takes differs, but it certainly should be done within 20-30 mins. Not sure where to go from here, will do a little looking around and get back to this thread.
FYI, you might want to know you are in the Nexus 7 2012 forum. You may want to self-report your OP as a maintenance request and have it moved to the Nexus 7 2013 forum.
And with that thought, make sure in future, that within wugfresh tool, you are selecting the right image, as if you try and use the N7 2012 one you may have issues.

Sorry to trouble you again. I don't know if the userdata erasing is done, but I got this (screenshot). The tablet is still frozen in the selection screen (highlighted "Yes, unlock bootloader").
I shut it down and started it into fastboot again. Under LOCK STATE it's still locked.

I'm suspecting it could be a bad usb port or bad usb cable. i.e. try a different pc, or a different usb cable and different usb port, also never use a USB hubs port. It also could be a dirty usb port on the device too.

I tried a different USB port, and also on a different laptop, but nothing seems to work. It seems to be stuck at "erasing userdata". I tried fastboot -w too, but it just stayed at "erasing userdata" for over an hour.
I'll get a new USB cable whenever I can, and try this again. Thanks for all the help so far!
I can't believe an official OTA update would cause so much damage. SIgh.

So apparently I'm not the only one with this problem.
http://www.androidpolice.com/2015/0...rate-not-likely-a-result-of-firmware-updates/
I used my Nexus 5 original USB cable to do it, and the same problem has occurred.
I feel like I'm running out of options and seriously losing hope. I know it'll probably be better to leave the device on its own and wait for some kind of fix in the future, but I'd also like to know if there are any other way other than sending it in for repair (I rather buy a new tablet).
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 !

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.

Hi. I cant get anywhere near recovery. When I press both buttons without the power button nothing happens. Thanks though!

The moment I plug in any cable the screen turns on automatically. I've tried everything at the phone won't go into EDL. Thanks though!

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

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 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
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?
