Bricked on RROS 7.1.1 - ZTE Axon 7 Questions & Answers

Basically I am dealing with a soft-brick that happened because I saw that the "Enable OEM Unlock" option was disabled and re-enabled it. After rebooting the phone just loops on the boot animation.. Is there any way to fix this without data loss? I know it is a huge stretch. I can access TWRP if necessary.

Haven't attempted bootloader/root, yet I'm soft bricked...

Last night I noticed that my N7 backlight was on but it wouldn't respond to anything; I reset it by holding down the power button. Now it won't get past the Nexus logo and I've been waiting for over an hour and multiple resets.
Just as it says, I haven't even attempted to unlock the bootloader or root my Nexus 7 2013, yet it's now soft bricked. The only thing that potentially could have soft bricked it was that SuperSU and BusyBox Pro are installed onto the device (Google automatically installed them from my previous Nexus 7 the first time I turned it on); it was my understanding that since the Bootloader is not unlocked and I haven't rooted my device, that these programs would do nothing so I never bothered uninstalling them.
What in the world happened?!?
Also, and more importantly, I'm a bit unsure of how to fix it. I found this thread: http://forum.xda-developers.com/showthread.php?t=2381582 , but every time I try to run the .bat files it says: 'fastboot' is not recognized.
Thanks in advance for your help.
Unlocking your bootloader would wipe your data and reset your tablet.

OK, thanks. I'll do that and update this thread and see if that fixed it.
But do you know why my N7 was soft bricked in the first place?
OK, I got it working again, although it's worth noting that even after I unlocked the bootloader, installed TWRP, AND rooted using SuperSU, it still wouldn't work and would get caught up on the Nexus logo screen. It didn't work until I went into TWRP and hit: Wipe -> Format Data. Only then did it work.
That's good...

I had the same problem but I kept getting password on twrp so I followed what you did and wiped my device now Im still stuck on the flashing X any ideas how to fix this.,,, I did wipe data...

Phone restarts at startup.

Well this is my 1st post so first of all hey everyone
I just spent a week in Amsterdam and my phone restarted twice, different times different days and I dont remember what I was doing with it back then.
But as I landed back home I put the phone back from "Airplane Mode" and went on to toggle "Cellular Data" on.
The second I pressed the cellular data shortcut on my the phone restarted itself but this time whenever it would finish the screen would be on but fully black and sometimes it'll show battery precentage at the top but then will restart again in an infinite loop.
Sometimes it'll pop up the "Optimizing Apps" window and will go through all 24, upon finishing it will restart once more and do the same.
I tried using the bootloader and it worked (the bootloader that is) but the phone would do the same thing even after Rebooting from there or shutting down from there and then turning back on.
I contacted tech support on chat but they couldnt help past telling me to go to bootloader and reboot, said I should factory wipe when it failed.
Also tried wiping cache but to no avail.
I have no backup of my phone (wanted to do one before the flight but got lazy and I suck for not doing one sooner) since probably October and google doesnt backup my contacts properly for some unknown reason.
I already downloaded Android Studio with everything included for me to try using adb to sideload stock without wiping but its my first time and I couldnt get it to do anything at all...
I already got the official stock .gz file from the motorola website.
Anyway here are the specs to my phone:
XT1575
Everything is stock. didn't root or change recovery once in my life.
Was fully updated and had plenty of drive space (I have almost 128GB with the 64GB version + 64GB SD)
I'm really lost here so help will be very appreciated.
Thanks in advance,
-Noam
Start with a full wipe and if that doesn't work flash the stock image. Not sure what your question is though as you never really say. Once fixed I would unlock and make a backup so you don't have to deal with this again.

The thing I pretty much want to know is if theres a way to either backup the phone now with it connected to the computer while in bootloader or recovery. or a way to flash the stock rom without wiping which I read someone did with his tablet. I cant post source normally because I'm a new user so here it is but change spaces to dots: schnouki net/posts/2014/08/13/flashing-a-stock-android-image-without-wiping-user-data/
Also while in recovery I noticed 2 options under wipe: 1. userdata only. 2. userdata+(insert something I dont remember here) and I was wondering what gets deleted in both? if I delete only userdata what data will remain? something helpful?
Sure you can try flashing without wiping data but being locked I personally wouldn't risk it. No idea about backing up in your state... somewhere I remember a thread on backing up without root try searching in q&a.

Out of curiosity why shouldnt I try flashing with no wipe if ill lose the data anyway? worst case wont I just have to wipe after it fails and flash again?
And I will try thank you
Do you have any knowledge about the 2 wipe options?
Thanks in advance
Well I tried turning the phone on and it took a couple of minutes before loading to a fresh start. It apparently wiped itself on its own. Managed to restore almost everything.
Anyhow the phone takes too long to boot now. Was even stuck at boot and I had to restart it.
Anyway to fix my software? Or at least check for corruption?

Is my XT1575 recoverable?

My XT1575 just decided to go into a bootloop a week ago on its own, literally. I was just checking traffic on Google maps when I noticed it started to lock up. Finally, I see the Motorola splash screen, and that was the beginning of it. Went into recovery mode and tried a factory reset, clear cache partition, etc. but no luck. I've tried everything under Android 6.0 here but it continues to bootloop no matter what I do.
It's not rooted and the bootloader is locked, so I don't think I can even install TWRP or any custom recovery. I have never even though of enabling USB debugging so that's out of the question. What's odd is after trying all sorts of things, sometimes, after the phone has been off for a while I would power it on and it would actually boot into the Welcome screen. Shortly after that though, it locks up and starts bootlooping again. I don't know what else I can do about this or if it's recoverable. I hope someone can help. If it's of any significance, when in recovery mode, at the top I see what I think is the firmware it's currently on -- motorola/clark_retus/clark 6.0/MPHS24.49-18-4/5. Please help!
Update - After having my XT1575 powered off overnight, I powered it on this morning and it was able boot all the way into the Welcome screen, setup, etc. Right away I went and turned on USB Debugging and Allow OEM unlock. Tried rebooting and again it fails to boot. What's weird is it randomly seems to boot when it wants, and something must be corrupt but I just don't know what it could be. Does anyone have any ideas?
Don't unlock the bootloader.
If it is locked and behaving that way you should be able to get a warranty fix out of Lenovorola. If you unlock the bootloader you void your warranty, and they might choose to not honor it even if you say the problem started before.
Painful and slow as it might be, I'd recommend working with the manufacturer on this one.

I'm afraid it's too late for the bootloader, since it was one of the things I was trying out of desperation. After trying fastboot flashing the stock firmwares, I still get bootloops and strangely enough I was able to use the phone the other day for several hours before it started bootlooping again Thing is, it seems to behave differently at random times. Sometimes it makes it all the way up to the "Android is upgrading" screen but then freezes and reboots.. Other times it locks up at the Motorola splash screen and reboots.. And sometimes it even boots all the way up, is usable for a little bit, then begins bootlooping on its own.
I'm just wondering if something is corrupt software-wise (boot? system? etc?) or if it's a hardware issue. How do I even tell at this point?

The random nature of what you're describing does sound like hardware. Consider a full restore where you fastboot flash everything back to stock of you haven't already.
Check logs. See if you're getting anything in last_kmsg. Use an app like syslog if you aren't used to pulling them, though you might have to use adb if you aren't getting through boot all the time.

Thanks for replying. I've tried fastboot flashing everything and even going into recovery and clearing cache partition as well as doing a factory data reset. I'm afraid it may very well be hardware. I'll try your suggestion about the logs.
Is 'last_kmsg' a line I should be looking for in the log? If so, what would I need to see in order to determine whether or not it's a hardware problem?

/proc/last_kmsg is a log file that should get written to if a kernel panic causes a reboot in theory. In practice I find it is often blank even after a random reboot.

going by that logic the thing that you should have done was get a factory image from moto and flash to stock using moto tools if that failed at fixing it then send into moto it might not be lost yet but the more you progress the more less likely to replace the phone moto is...
it sounds like something is going bad could be ram emmc or the soc
What i would do is get into discussions with lenovo to see if they can get you fixed up. if you unlocked the bl they know be straight with them. if you get nowhere and no rom you load can fix it sell as parts replace at your expense...

How to decrypt the Axon 7?

OK so this is totally self inflicted. At some point I was dinking around in the settings and the device asked me if I wanted to set a pin at startup. I went along with it and did that thinking it was a good idea. What it seems to have done (besides the startup pin) is encrypted the phone. Now technically everything works I can just enter my pin to boot to ROM or TWRP. But I want to remove the encryption and for the life of me I cannot find how to do that.
Any help would be GREATLY appreciated.
Here are notes on my situation:
-yes i searched the internets and XDA and mostly found stuff about the Nexus and OnePlus devices
-under security settings it just says "encrypted" there is no option to decrypt
-i have tried wiping and even formatting to different formats on data and system partitions
-tried different roms as well
-this is a Axon 7 U device
-running TWRP 3.1.1-0
-ROMs RR and Dark Rom
-obviously boot loader unlocked
Thank You

Remove your PIN and then add it back but this time when it asks you if you want the startup pin choose no thanks.
Startup pin IS encryption.

I had tried that earlier and it did not work. What did work was doing doing a format data in twrp. I think mine was just stuck.

i believe that's the only way to decrypt the phone. You can have your phone encrypted without jt asking for a pin or pattern and startup, and it happens every damn time you forget to flash supersu or magisk on first boot. If you flash another ROM later you'll have to format data, or it will fail if it is encrypted.
If your phone has TWRP I suggest that you go to it and format data, then install supersu/magisk via sideload or an sd card or otg without rebooting.

HELP: Encryption Unsuccessful TB-X104F

I i had to reflash the firmware the correct one TB-X104F_S000024_180930_ROW_DCC. Anyway it wasn't booting at all before i flashed. Now it boots, shows the logo etc and constantly says Encryption unsuccessful!, so i reset it and factory reset it but nothing changes.
I have no idea where else to go, bootloader is locked and all i can do is flash the firmware. Would there be a way to remove this from the files within the firmware?. It seems like android is there in the background but i can't get away from that encryption unsuccessful screen!
Sorry if none of this makes sense.
Yo. I got the same tablet bro. Been trying to figure out a custom recovery for her. A stock ROM would be great to have and I haven't been able to find one anywhere. Might I inquire as to where you found yours? It would be a huge relief to know I can fix it if I break it lol.
encryption
If you download the Lenovo MOTO smart assistant from Lenovo support it has a resque option. I also used that to root my tb-x104f. It downloads the original everything and if you take the boot image from the file it downloads and replace it in one that has been modified from magisk it will rescue it and you will have root also thatd what I did with mine
same problem here, reflashed with stock rom. and not resloved

Did you fix this issue?
I am having the same problem.
Thanks
Same problem here (my error reads "Decryption unsuccesful", but I think it's the same as yours).
After a few tries, I believe that it is a problem with the internet connection. After the factory reset, if I skip the wifi connection step, it starts normally. And it is completely usable. I can load pdf documents or apks by the usb from a computer and it runs correctly. But whenever I try to set the wifi connection, it updates something and it causes the tablet that the next time I turn it off, I find the error on the picture when turning on. It asks for a password and no matter which password you enter, then it delivers this message.
In resume, right now it is a completely functional tablet if you NEVER connect it to the internet and load anything you need via usb or bluetooth.
I tried to reset it with Lenovo Smart Assistant, but the result is the same.
I am looking for custom roms to try if it's something about the stock rom, but I haven't found any. Can anyone reccomend me a rom for Lenovo E10 X104F 2GB?
Solution: (Worked for me)
Format Data as F2FS in TWRP. (Advanced Wipe)
Then reboot and wait.
