I tried relocking the bootloader and messed up - ZTE Axon 7 Questions & Answers

[SOLVED]
Hello, so i followed the guide on here to go back to the stock rom from LOS(Lineage OS). I had done that right. Then i tried relocking the bootloader. I did that successfully. Now, i have 2 problems i have run into.
1) there is no recovery mode
i tried booting into recovery and all it does is flash the ZTE logo for a second than turn off. This keeps happening. I am not sure how to flash the recovery image since the bootloader is locked and i have no recovery mode.
2) when i boot my device, it asks for a password (a 3x3 grid).
I tried typing in the password i used for TWRP and it didn't work. I tried a bunch of old passwords but so far nothing has worked. I would like to know how to get the password and turn this off. I found this very annoying on LOS.
Please help me as i am not sure what to do!!
edit: i cannot seem to get the device to conect to the computer using adb or fastboot.
if you can can we excahnge phone numbers to fix this faster?

[Q]Mobile network stopped working after Installing Custom Recovery!!! Urgent!!!

Hi Guys!!
This is emergency!! I was trying to install recovery . I was successful in flashing recovery through the Nexus 4 Toolkit. After a while non of the networks are connecting. Wifi dosen't even startup, no mobile network! Please HELP!!
Thanks
In settings, does it display an imei number or is it 0's/garbage?
Maybe you need to input your apn settings for your carrier again? I know one of the tool kits I used had an option to backup apn settings probably for this exact reason. Try rebooting your phone also.

Did you make a backup of your efs folder? Or any backups? What you have is a missing imei number.
Ship it to me and I'll fix it for you.
Did you try flash the AOSP image from Google's website?

All the info and resources you need are there.

What you did and don't realize is that you had to unlock the bootloader to root and install a custom recovery and by doing that you wiped your phones data, all of it. Unlocking the bootloader puts the phone back into the state when you first received it and it has to be setup all over again.
Flashing the stock image will also take you back to a state where the phone was when you first received it and you will have to set it up again.
I'm not absolutely sure you need to do that or just set the phone up again like you did when you first got it. If you can't get it working again then reflash the stock image and restart from there. To do it with the toolkit you have to download it manually then place it into the folder in the toolkit directory for flashing files. The toolkit should have instructions on how to do this.
Unfortunately at this point anything you had stored on the phone is gone for good.

Dude i had already unlocked the boot loader. Now i am in the Start screen and the Lock Status Says : Unlocked. Luckily my Nexus is jus 1 day old and am yet to load stuff! So not much to bother about loosing data on the storage. I am downloading this : Factory Images "occam" for Nexus 4 - https://developers.google.com/android/nexus/images i hope it is correct!! Thanks
Edit:
Re flashing the factory image fixed my problem. Thanks a lot guys.

ok. i was on stock. rooted with the IO method. wanted to flash a ROM (clean rom). downloaded ROM, wipe dalvik/cache/data. after reboot, phone booted into recovery mode. tried going into download mode to revert back to stock and LG FlashTool failed. said phone was the wrong model number (D802). the ROM i Downloaded said it was for VZW G2. obviously it wasnt. so i finally ended up using fastboot to push boot image and it booted, but in about phone, it says it D802 model (i just got it to boot, where as before i was stuck in fastboot mode). now i need to return to stock, but dont know how. any ideas?

yes. not sure why its doing that. is there any way that download mode can be deleted from the phone? also, how do you get into fastboot mode?
EDIT: nevermind. i finally got it into download mode!! (thank god!!) flashing right now. damn that was a pain in the ass. i was starting to freak out that i messed up my phone. this is my first LG phone so this process is a little new to me (been on moto for the last few years) thanks for trying to help me out. this was def a learning experience.
Phew, I'm glad to hear that. Some day I will be in the same situation

Just a quick question. Why would you even need to go into download mode to flash a Rom? Never once have I done that. Really, just curious.
Thanks Devs. From my VZW G2.

I was thinking the same thing. It's best to stay out of those modes. Get a recovery installed ASAP and do everything that you need to do from there. I recommend TWRP Recovery.
Sent from my LG-D802 using XDA Premium 4 mobile app
Maybe because when flashing stock rom download mode is needed (atleast in my old sammy phone, maybe same in moto phones)
What's wrong with restoring the backup of the stock rom that should have been made before wiping and flashing a different rom? Not sure what I'm missing here.
Sent from my Nexus 10 using XDA Premium HD app
Download mode is useful to flash the entire phone back to stock using the OEM tools. It's not just for the stock ROM. It's everything. It's useful if you get a bit carried away in TWRP and wipe partitions you really shouldn't be touching. Or if you somehow manage to bork your recovery, or at least can't get into it. It's also good if you want your phone to be completely stock to sell it or to send it in on warranty. I'm sure someone could come up with other scenarios where it's useful.
But yes, it is a good idea to keep a backup of your stock ROM. And as always, know what you're flashing, make sure it's for your phone and check md5s. And be mindful of what you're doing in recovery. You should be able to avoid most issues. Download mode is indeed something you shouldn't be using often but as I said above there are situations where it is useful or necessary. It's actually something I suggest you know how to use. I say it's always a good idea to know how to get back to complete stock for warranty stuff, selling, or if something just goes majorly wrong.
The Rom I was trying to flash was apparently for a different model number, yet it was under the Verizon thread. There was no md5 to cross reference. In the end I ended up finding the proper boot image/twrp files and pushed them via fastboot (since I was unable to use adb) which then allowed more to restore a backup of the original Rom. Just took me all night to finally get back to stock. Then I decided to restore to out-of-the-box stock just to make sure all files weren't corrupted our anything.

Not for nothing, but I ran the LG flash tool without putting the phone in download mode and it worked fine.

You can you adb side load which is the same for flashing rom, pushing, or pulling file from the phone which is the first thing to learn before flashing anything to the new device that you got and know nothing about.

check this thread out. I had the same thing.http://forum.xda-developers.com/showthread.php?t=2432476
this reverts you completely back to stock. You will lose all your data but you did back up regularly, right?
(edit) you only have to hold the volume UP key while plugging in the USB on a D801 to get into download mode.
Make sure you've disconnected usb when attempting to enter recovery. Hope the silence means you've sorted it out!

If you're trying to unpack the ROM try redownloading the rom.
You're saying that you have CM installed? I had this exact problem and I had PA installed.. it was a mess. I had to sideload the original ROM because to flash with that program your build.prop has to be the original information when you received the phone or else the program will throw a "different phone model"
Do you have the LG usb drivers? Install all proper USB drivers and try to sideload an original ROM.
BTW do you have any backups? Restoring also gets you out of this mess
never mind i opened the wrong folder thanks for everything guys it worked perfectly ^.^

In case you don't know, you can supposedly get rid of it by displaying an all-white screen (with display brightness turned down to preserve bulb life).

With no root, the only way to get rid of this bootloop is to factory reset, you can do it in recovery by pressing volume down + power at the same time, then you choose Recovery with the volume button. BUT you will loose everything ( pics, apps, etc. ).
But I hope that someone can give you another solution less "destructive".

Can he do a back up using ADB and then do a partial restoration after a factory reset?
Will adb backup work if the phone's not booting? .. I know that adb works when in a bootloop, but in the guide it shows a prompt to enter some encryption password ... I summon android wizards to answer this ...

Essential Phone Stuck in bootloop / soft brick?

Good morning all,
I am throwing this out here hoping someone can please help.
Woke up yesterday to the Essential phone logo screen powered by Android... Unresponsive. Restarted with no luck. Went into recovery mode and factory reset. Went to start up animation for an hour but nothing. Device is locked (bootloader locked) and running on the latest build from Essential (7.1.1/NMJ88C/464). I have never unlocked nor flashed anything on the phone, only OTA updates directly from Essential. Just started it up again today and says your device is corrupt. Factory reset again and now cycling between logo screen and erasing circle.
Any ideas to fix the phone? Reached out to Essential but haven't heard back yet.
Thanks all!
