A while back i unlocked my bootloader and installed TWRP 2.8 (via fastboot) but that was way back ago. Later i tried installing the OTA update via the phone directly which didn't work so i didn't bother as it didn't affect much. But today i was about to install a new rom but i couldn't boot into recovery(booting into recovery via advanced power options, it just didn't work anyway) I thought i might as well reflash recovery using the fastboot method again but when i used fastboot oem unlock command ( I know i used it before i thought i had to do it again im so sorry) it just flashed the one plus logo, vibrated and redid the same thing again and again with no chance of booting.....after using command fastboot continue it booted ! ( God thank you !) but the phone only boots via fastboot continue command I need to get it back to normal !
Also I checked fastboot device info, it said device unlocked and device verified =false ?!
So my BOOTLOADER is locked on its own ? plus recovery isnt available ? AND it doesn't even boot the normal way?
Im really worried now ! please assist me ?

Use the usual Qualcomm factory restore to revert everything back to working Lollipop software. From there you can try anything except OxygenOS 3.0 Beta or latest HydrogenOS without having to change to compatible recovery for those bootloaders.
Next time, at least try to use the search function, your case is nothing new and has already been answered many times over since the release of OOS3 beta and HydrogenOS Marshmallow ROM.

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
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

Alright so where i'm at now is basically the aftermath of a failed attempt to install a cyanogen unofficial rom for my phone.
I have a p9 lite VNS-L23 dual sim and well basically, i unlocked the bootloader and i rooted it with twrp and installed superuser using the srk tool. Everything worked fine up to this point until i booted into recovery, cleared cache and data etc to do a clean install and the install failed with an error code 7.
I thought doing a twrp backup before the flash was effective but because it didnt take any length of time, i sort of thought it definitely wasnt a full backup but i didnt pay it any attention and tried to flash it anyway since iv'e never had probs flashing anything with other of the phones ive had before which was my main mistake.
Usb debugging was enabled before trying to flash. I thought it failed because i didnt change my file system but i had no idea how to do that so i avoided it and tried to install a newer version of twrp to see if the rom would work with the updated version instead. When flashing the twrp img file, it asked where i wanted to install and i think i selected bootloader instead of boot cause there were only 2 options.
After than finished and i chose to restart in recovery, recovery never loaded. I was getting erecovery but that couldnt help me either. I was just stuck with no os and a phone stuck on the bootscreen. I tried to unbrick my phone by installing the update file for the international version firmware which i downloaded which was the only one not to fail after trying 2 others before it before realizing the error i was making. I read online that it would restore my phone back to ofw and that was great considering i had no os installed. Now, after the update, i think i reached like 100% then it went blank. I tried to wait a couple seconds to see if it was rebooting but nothing happened. tried all button combinations with and without the charger for varying lengths of time but no luck. I hear a sound when its connected to my laptop tho so idk if that matters. Its a bit frustrating right now and i have no clue how to fix this problem and i havent even had the phone for a long time. If someone. anyone can help me, id more than appreciate it
So far, nothing is responding to anything. No lights, no vibrations and i dont see anything when it conencts to my laptop, my laptop just makes the connected sound. I see Fastboot 2.0 detected but the srk tool cannot detect any emulators or devices :/ im so depressed at this point. More or less just bought the ****.
Sounds bad, try using the dload method and if that doesn't work you are ******.
What is the output of "fastboot devices"

its the dload method that has me in this mess. It didnt reboot from the upgrade and since then i think ive been in fastboot mode. I get a response with the fastboot devices cmd and i manage to flash the boot, recovery and system of the stock firmware but still no luck. Think my only option is to use dc phoenix but i cant buy credits for that

not getting to the upgrade screen with dload, the phone restarts but nothing on screen. I can use fastboot only to flash and unlock bootloader, check specifications but thats it. I flashed the stock image which is mm thru fastboot but no luck. I read that i might wait for my battery to drain since my battery isnt rly made to be removable. Can i still use dload without any on screen response?
Have you also tried flashing vendor, cust ... partitions ?

Fastboot doesnt flash certain img's such as xloader etc, no vendor img included inside the update but i doubt i'd be able to flash it anyway, but i flashed everything i was allowed to incl. cust, boot, recovery, system, cache, . Everything else is giving error: command not allowed. I've hit a brick wall so far til my battery drains or i take it to a repair shop which is i guess, last resort. Can't seem to find help anywhere on the internet, nothing returns anything to the screen.
Looks like a hard brick, take it to an official repair shop. But remember: unlocking the bootlader does NOT void the warranty.
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)
Hi guys this is a strange issue, i was on omni rom 8.1, (unlocked bootloader, got my ta backup) and i though i just go back to stock, i flashed stock oreo 8.0 34.4.A.2.32, when i try to flash boot_32.img i got a bootloop, and i cant enter fastboot because light turns green, SOmmc flash device shows up in device manager, but i can easily flash any firmware i want with flashtool.pc companion says i cant fix firmware because of unlocked bootloader. Need a little help here :/ i can go back to omnirom 8.1 which i dont really like yet or to stock rom but with bad camera....
p.s i can easily enter fastboot through: adb reboot bootloader ... but i need to get to fastboot with phone already off to root. i tried different adb fastboot drivers, disable drivers signature, nothing works much...
Can i somehow flash tabackup.img without fastboot and root on stock oreo?
Edit: managed to get to fastboot.... it was volume up on my device somehow................
