Phone bricked, Recovery Tool not working, bootloader stuck locked, help??? - OnePlus 2 Q&A, Help & Troubleshooting

Hi guys...
So my OnePlus 2 was having some issues yesterday, and I flashed the stock ROM. This was completely fine and dandy, but I also wanted to put the stock recovery on it. I made sure OEM unlocking was on, went into fastboot, and typed in "fastboot oem unlock" like normal. It finished in like a tenth of a second which I thought was a little strange. The phone rebooted and I put it back into fastboot. I tried to flash the recovery and it said (remote device is locked. Cannot flash images). So at this point I was frustrated. I went into TWRP and installed the SuperSU binary. Then, I went to the Play Store, downloaded Flashify, and flashed the recovery onto my phone. I restarted my phone.... and bam. Recovery wouldn't work anymore. And then when I tried to boot into normal Android it still wouldn't work, just stuck on the OnePlus and Android screen, as if there was no /system/ partition. I can still get it into Fastboot, and I put it in EDL mode and installed the Qualcomm 9008 driver, and flashed OxygenOS 3.0.2 through the MSM downloader from https://forums.oneplus.net/threads/updated-28-06-2016-mega-unbrick-guide-for-a-hard-bricked-oneplus-2.347607/ and the MSM downloader just gave me an error that, in garbage text, said something about Sahara and Firehouse or something like that. I did get it to go successfully by downloading a different recovery package (I believe it was Color OS 2.0) but I have a ONE A2005 and I belive that was meant for ONE A2001 and it caused my phone to constantly flash rapidly at the Oneplus and Android screen (it would start to boot then immediately shut off). Fastboot still works but it still says the bootloader is locked so I can't really do anything. Any help would be much appreciated!

Update: I finally got Recovery to work. However, it still gets stuck on the OnePlus & Android screen, even after sideloading a stock ROM and installing it via the stock recovery. I fear my boot.img is corrupted. Does anyone happen to know where I can find a stock ROM that comes with recovery.img, boot.img, system.img, et cetera?

Actually, nevermind. It says oem unlock is disabled, and I can't even get into the OS to enable it.

You should be able to unlock it in fastboot or adb
OEM unlock or something like that

Stuck on Bootloop & FirstAid kit won't help. Any Ideas? Please Help

Hello everyone!
Okay, so I'll try to keep it as short as possible but with the most information I can give ofc.
So here's what I did with my Oneplus 2:
- unlocked bootloader
- flashed custom recovery (twrp)
- flashed superSU.zip
- flashed xposed.zip
- used it for about half a year if not even longer
everything on Lollipop 5.1 stock rom so xposed would work.
Everything was fine but some day when I wanted to enter twrp recovery it didn't work. (I swear, this is the most illogical thing ever but I DID NOT CHANGE A THING!)
I tried to enter recovery via fastboot but that didn't work either.
So I reflashed latest TWRP recovery.img for OP2 via fastboot.
When I pressed power + vol. down to see if it'd work nothing happened.
When I tried to enter recovery when my system was booted via power button->restart->recovery my phone got stuck in a bootloop.
I had to go in fastboot mode to enter "fastboot continue" in order to get my phone booting normal again.
Then, one night when my phone was in my pocket it vibrated and got stuck in the bootloop again, even though it was booted into system and locked last time I used it (minutes before that).
I had no access to a computer at that moment so I had to wait for a few days.
Now when I boot my phone in fastboot mode and try to enter "fastboot continue" on my cmd nothing happens with my phone and cmd says "(command write failed (Unknown error))" even though "fastboot devices" shows that my device is connected properly.
I also tried:
- the FirstAidKit, copied the Win Files in my fastboot directory and started the firstaid.bat but it stops on "fastboot flash boot boot.img" (I waited for like two hours).
- a different USB port (USB 3 and USB 2)
I am kinda depending on my phone so yeah..
If someone knows how to fix this I would be very grateful.
Have a good day/night

Do you have a backup??
If yes, download the latest official OS from Oneplus and the stock recovery. Flash the stock recovery. Try rebooting into stock recovery. If it succeeds, wipe everything and flash OS via adb sideload.
Honestly, I can't guess what went wrong with your device. Maybe it could've been some app which crashed the entire system.

Flash the stock recovery.

Same problem as with the FirstAidKit:
"fastboot devices" does display the device but "fastboot flash recovery recovery.img" doesn't do anything (I waited for 1h just to make sure).
I'll try this Mega Unbrick Guide for A Hard Bricked OnePlus 2 next, even though I can get into fastboot but since it doesn't do s**t I'll have to give it a try. I mean, what's the worst thing that could happen? That my phone gets bricked?!
Haha.... hmm.
I'll keep the person(s) updated who care to know what's happening.

Need help - Stuck on Google logo after flashing stock and re-locking bootloader

I was running Pure Nexus. My camera won't focus at distance, so I was trying to revert the phone to stock before RMAing it.
I used #10 in this guide (https://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928) and flashed all the pieces.
This is the zip I used for the images - https://dl.google.com/dl/android/aosp/angler-n4f26o-factory-c53f0a50.zip
Then I formatted userdata, relocked the bootloader, and tried to reboot. It's now stuck on the Google logo. It doesn't look like it's looping, it's just stuck.
I can boot into the stock recovery, but since it's a fresh install, USB debugging is not set so I don't think I can ADB anything. And since I locked the bootloader, I don't think I can fasboot flash anything either.
Am I out of luck?
Since I was going to send it back anyway, should I just blame the return on the fact that it won't boot?
Thanks
Edit: Huh, I think I got it to work. I had tried the guide to flash a full OTA as a fix, but when I got to "ADB devices", it wouldn't see my phone. But I tried it again, and it did see the phone and I was able to flash the OTA. It's rebooting now.

Please help! ZTE Axon 7 won't boot after deleting Lineage and TRWP

Hi,
don't know if this problem has already occurred before.
I had lineage and TRWP installed on my Axon 7 (EU version) and wanted to go back to the stock a2017g.
Therefore I deleted the ROM and wiped everything with TWRP.
Then I deleted TWRP and now i'm stuck at the the bootloader (which is unlocked), but TWRP seems to be gone.
The main problem is, whenever I try to flash a new stock rom (via recovery), I get the error "signature verification failed" and the process is aborted with no change to the system whatsoever.
Is there anything I can do at this point or is my phone practically dead?
Thanks in advance for any help.

Try to boot into bootloader interface, and issue command "fastboot flash recovery TWRP.img" on your computer( the current working directory should contain the TWRP.img file) . If your bootloader is unlocked, you should see no error of this command. Then press up/down button to select recovery mode. You should see the familiar TWRP again. Good luck!

Did you try flashing an official full zip, like B10? That's another thing you can try, since you're going to lose TWRP after you flash a stock rom anyways
If you dont have recovery, flash it from edl mode, you can flash twrp or stock.
Once you install it, performa a full wipe from stock recovery, and flash a full zip.
I have similar problems, I dont loose recovery, but stock dont boot after coming back from aosp, a factory reset did the job. I think is because different filesystems in data partition

Hi, the B10 ROM from the ZTE homepage did the trick.
Worked out nicely.
Thank you so much.
One final question remains for myself: How can I relock the bootloader (so that the 5 second screen won't show up at the start).
Tried different ways with adb and fastload, but nothing seemed to have an effect here.
So what to do?
Thank you again for your help.

you shouldn't. Fastboot should do the trick, by doing fastboot oem lock, but many people reported bricking and bad stuff...
Actually that screen comes very handy in case of a brick or if you want to enter a specific mode.l, you just select the mode and voila
Do you have fastboot? I don't know if B10 still has it, but 7.0 hasn't got it

Hi,
I tried adb and fastboot via pc and with the axon toolkit.
The adb worked fine, but no sign of effect by the fastboot commands.
So I guess I don't have it.
Is there any other solution to at least bypass the 5 second screen?
Thanks

Lol fastboot is not something like EDL, it looks similar to the 5 sec screen...
When you get the 5 sec screen, use the vol keys and pwr to get to the Fastboot option and enter - it should reboot and get to fastboot after some time
You should look up what fastboot, EDL, ADB and DFU are before doing all this stuff - you can mess up badly, and by not knowing you're complicating everything - my explanation and your understanding

Corrupted recovery, no o/s, what to do now?

I have a Axon 7 A2017U, bootloader unlocked. My recovery is corrupted after attempting to flash a older version of TWRP in recovery. I can no longer reboot into TWRP via recovery, it hangs at the ZTE powered by screen. I can't boot into the o/s, it too was corrupted while attempting to restore to stock using the DrakenFX's guide.
Booting into fastboot is a no go either, it just hangs at bootloader screen.
Any suggestions on where to go from here or how to fix the corrupted recovery?
You need to go into EDL mode and use MiFlash and flash a back to stock package. You can find a package here: https://androidfilehost.com/?w=files&flid=160532
Hello maybe i have same problem here. I have A2017G and maybe i have only woked unlocked bootloader. I dont think my EDL is working becouse i cant connect with ADB. Dont have any acces to recovery... i messed up step by step remember.
1. downloaded toolkit and woked fine - 2 installed drivers and working fine with EDL. 3 unlocked with no problems , 4 flashed TWRP with no problems and then i wanted to install lineage os. Downloaded last version lineage , and google apps and one file "A2017G_N_Modem.zip" and put all 3 files on my SD card. I wipe everything and then first installed modem file OK, but on second try with Lineage OS i have any errors and i just cant continue. After this i wanted to go back to original OS and i just locked my bootloader with axon toolkit and after restart i have acces only to Unlocked Bootloader. tryed everithing with axon7toolkit but nothing working. If i try to EDL mode when press volumeUP+volumeDOWN+power my phone have black screen and i thing is powered OFF.
OMFG i just typed "fastboot oem unlock" 5-6 time when i started phone to my bootloaders and now it unlocked and have acces to my TWRP.

Thanks, I flashed it with A2017U_B19-NOUGAT_FULL_EDL and was able to flashed twrp recovery. I was hoping the o/s would be fixed too but I get this error message as soon as o/s load "settings keeps stopping, close app". It appears it's a bad or incorrect stock file. I had to format data in TWRP recovery as the drive was encrypted. So now i'm back at square one.
Bad o/s but working recovery, so I attempted to flash these files to get back to stock but was unsuccessful. It would flash halfway and then just restarts and hung at the bootloader unlock screen.
A2017UV1.0.0B29_RollBackModded.zip
A2017UV1.1.0B32_bootstack_by_DrakenFX.zip
A2017UV1.1.0B32_StockSystem_by_DrakenFX.zip
Am I on the right track? Or should I be flashing with a different os variant?

So you didn't read all of the hurdles and warnings about locking the bootloader with non-stock firmware?
Plus you also didn't find out about the Universal Bootloader? Did you even read the installation steps???
You had an error 7, which is that you forgot to install the Universal Bootloader. Do so this time.
EDL has nothing to do with ADB. You can access it with the phone completely off... (volume up and down, and insert usb)

I think i really messed up

So here is what happened. I decided to take a crack at twrp and rooting my essential phone. its fully updated to aprils patch
unlocked my bootloader. HOWEVER i never used the command fastboot flashing unlock_critical. how ever it still said my boot loaders unlocked.
installed twrp no issue (other then touch but i figured that out) installed elementalx kernal. made a backup in twrp just in case.
booted into android fine no problems. found out my wifi does not work. ok now im just giving up. found out flashing the boot img will fix it. well i flashed it via twrp and when it asked where i said to the boot.
now my phone boot loops. i cant get into twrp. only a default recovery mode for android. i can get into the boot loader but im scared because ADB cant find my device anymore. trying to wipe deivce makes it reboot and boot loop again.
am i screwed? i dont care about the data but its 3am and i think i really messed up my phone

Are you still bootloader unlocked?? Can flash files via fastboot? If you can run the command "fastboot flashing unlock_critical" and then flash bts from this thread https://forum.xda-developers.com/essential-phone/development/stock-7-1-1-nmj20d-t3701681
