So today I decided to root my phone. I unlocked the bootloader by following the instructions on htcdev and it was all fine. Skip forward to when I went to flash CWM Recovery on the phone. I flash it and select recovery in the Hboot menu. After selecting it, the screen would simply go black and no buttons would respond so I was forced to remove the battery and plug it back in. After doing that, it went back into the regular OS however, it said that the software was modified. At this point I had given up on the whole rooting thing and decided just to go back to factory settings so I relock the bootloader and press the factory reset button in the HBoot menu. This however did not work because it just went to the black screen. And now I can't unlock the bootloader again because it just goes to the black screen.
So now my bootloader is locked, with no root privileges, and I can't factory reset it. :crying:
My question is that if there is a way to simply just go back to the factory settings?

Factory reset won't fix either the "software modified" issue or the custom recovery issue. you just need to unlock your device again using the same Unlocktoken from htcDEV and flash the right stock recovery for your to get rid of the custom recovery. but I say let the custom recovery be, It won't hurt to have it.
to get to fastboot and unlock again, if your phone boots correctly to your Rom, connect it to computer, open your command prompt in ADB/Fastboot tools, and type " adb reboot bootloader"

That's the thing when I try to unlock it again with the same steps in htcdev it simply goes to a black screen and won't unlock. Same thing with the custom recovery. I can't actually go into it it's just a black screen.
Also when i tried the adb reboot i just get "adb server is out of date... ADB server didn't ACK."

have you checked to see if your adb works on another android device? maybe your platform tools are corrupted

I'll try to re download the files again and check.
Is there any other possible reasons as to why the black screen is happening for the custom recovery?

So I managed to get the adb to work and when i typed in " adb reboot bootloader" it took me to the fastboot menu.
What do I have to do from here?

The bootloader is currently lock. everything is stock, i never root it.
whenever i try "fastboot oem unlock" and select yes on the nexus, it frooze on this "unlock bootloader ?" screen. and on the terminal it say "erasing userdata". the first time i tried i let it like that for a good hour before force shutting off, and i tri again, froze every time.
I can acces to my stock recovery but i have an error "e failed to mount /cache (invalid argument)",
meanwhile, i can't boot
any idea to fix this ?

I've seen posts like this here and in other forums gleaned from fairly extensive searching. Nobody has an answer. I think it's a hardware problem, to be honest. The N7 2013 is plagued with them, it seems.
Can you still boot into Android? You could try to root via towelroot. From there, you could flash TWRP, or maybe unlock the bootloader with that app from the play store.
I would send it back to Google, if possible.

You can download the latest Google nexus image for your model tablet onto your pc.
Boot tablet into fastboot mode.
On the pc run the bat file to install the binaries, and after a few minutes the tablet will have latest factory bootloader, lte modem firmware, recovery, kitkat, and the tablet will have undergone a factory data reset.

The OP states that he was unable to unlock the bootloader. I was unaware that you could "fastboot" flash any kind of image without an unlocked bootloader! ; )
Hi all
Interesting issue that I've searched here and Google for and not getting far, my searching skills may not be the best though as I'm fairly new to this.
My Nexus 7 was working fine, put it on the side, came back and it's turned off. Thinking it's flat I charge it and try to boot it with no success. Pressing the power for a while does get it to turn on but it gets as far as the Google logo and stays there.
I've factory reset it in the recovery and nothing
I've tried to flash the stock image from Google but when unlocking the bootloader it just sticks on "yes" forever and nothing happens.
What can I do at this point?
Cheers

Have you heard of Wugfresh Tool kit ? (aka Nexus Tool Kit) It is in the development section or you can google it. It is quite famous.
It will do anything actually from drivers to repair a device stuck on google logo. Just make sure you select the correct option.
You will need unlocked bootloader to flash stock images. And to do either of those, you will need drivers!
Install drivers and use it to recover your device. If you still have trouble, quote me back and I will help you to my best of ability.
Look into the forum before posting your questions. There are so many similar problems and you can easily find a solution by reading their questions and their possible solution.
Good Luck!
I'm having issues with my nexus 7 (2013). It will not boot up,it's stuck on Google logo. I am able to put in fastboot mode. I'd like to do a hard reset/wipe but I cannot enter recovery mode; it just goes to the Google logo and doesn't show me the recovery menu. I thought I could try doing it through adb but bootloader is locked. Downloaded WugFresh toolkit but it requires correct build number, which I do not know. I tried different ones but everything fails. AND USB debugging is not enabled, but I cannot do it through my tablet because it won't pass bootloop. I haven't been able to enable it remotely. So, any help with getting this tablet up and awake?! It's not rooted BTW, its running stock 6.0 marshmallow

Interesting, and troubling for you, I'm sure.
-- What do you mean, in fastboot it doesn't show you the recovery menu? If you are into (more properly) bootloader mode, the Recovery option has to be there. Do you mean you just can't select it, or that it won't work when you do select it?
-- Using fastboot, you might be able to boot into custom recovery without flashing it. (e.g. "fastboot boot twrp.img", not "fastboot flash recovery twrp.img".
-- Have you tried unlocking the bootloader via fastboot? Is it possible OEM Unlock is already/still enabled somehow?
-- Also.... Wug's NRT doesn't need the correct verion/build. The last option in the drop-down menu on the NRT is this: << Android *.*.* - Any Build >>
HTH
-- When i go into bootloader/fastboot mode, the option is there for recovery mode along with 'start' and 'power off',etc.. However, when I select it,it just hangs on Google logo and never shows me the Android man and recovery options.
-- Sorry, not sure what you mean by this: "Using fastboot, you might be able to boot into custom recovery without flashing it. (e.g. "fastboot boot twrp.img", not "fastboot flash recovery twrp.img"."
I may need some instructions on how to do this please.
-- I have tried unlocking bootloader via WugFresh and Nexus toolkit and via adb but it hangs on erasing user data and also hangs on 'unlock bootloader's screen (left it for over 12 hrs). I doubt anything is unlocked.
--Yes, I tried the "any build" option and nothing works.
Thank you
I'm open to any suggestions.

Ah, right. I didn't read closely, and didn't realize you might not have used fastboot tools... and please, I'm no expert, so if I'm saying somthing inaccurate, I very much hope someone will correct me.
I'm never sure how much a poster knows, so I'm not sure if you meant you don't know fastboot commands at all, or just the specific ones I mentioned .. fastboot commands are like ADB commands, but run in the bootloader environment. We know you have fastboot commands installed and fastboot drivers installed on your computer because you have adb installed - which includes fastboot, and you said WugFresh's tool was able to run, which means you also have the right fastboot drivers (the NRT uses the same fastboot commands).
fastboot can be used to flash/install custom recovery packages, among a whole lot of other things. So what I mentioned in that command was a possible way to maybe get into a custom recovery if you have to do things like wipes or whatever, even if you can't actually fully install the custom recovery. You might need to do this stuff, if you can't unlock your bootloader and flash the whole official Google Factory Image from their website (which is what I'd try - simple instructions are right there, too).
Flashing the full factory image will wipe your device, of course, but there are simple ways around that, which you can find on this very forum. Good luck.
Let us know how you get on.

Hello All,
I am looking for some advice to get my phone working again.
I have a modified bootloader and S-Off.
When choose the recovery option in the bootloader it goes back to HBOOT after showing a brief android screen that mentions something about a development build. The phone does try to boot but gets stuck on the HTC logo screen. From what I can tell I have no OS installed and no longer have a recovery. I am also unable to get abd working since i cant enable usb debugging etc.
Any tips?
Thanks,
Matt
Were you doing something to the phone that led to this condition? If so, list those steps in as much detail as possible.

ADB only works within the Android operating system, however, as you noted, you have no OS. Instead, what you need is fastboot - which, if you can get HBOOT to come up, you have. There are several "kits" with fastboot versions, or you can download the full SDK, which will have it. It is similar to ADB, but operates at the bootloader level instead.
1) Since you are S-off, and presumably bootloader unlocked, just flash a new recovery from fastboot. From there, install a new ROM/nandroid from your SD card.
2) If you aren't bootloader unlocked, boot (rather than install) TWRP, and use the ADB bridge mode to manually reset the lock state using Scotty's thread. Then go back to #1
3) Or, if you haven't altered your CID/MID, just re-run an RUU and put it all back to a known state. (assuming there is an RUU for your CID/MID)
These aren't detailed instructions, but there are several threads relating to each tip in the forum.
I've got quite a problem.
A few weeks ago, I unlocked the bootloader on my phone and flashed SuperSu to root it.
Today I decided to lock it back for personal reasons, wiping everything.
After it wiped, the phone kinda softbricked. When it turns on the OnePlus logo flashes for a second and turns off.
Won't let me unlock bootloader again, got stock recovery. Tried to use sideload, but ADB can't read the file. My guess it's too large.
What can I do?
I had same problem. Follow the steps. Unlock it again and reboot to the system.
There enable developer option, enable debugging, enable unlock bootloader option.
Rebooted to fastboot mode
Install stock recovery
Adb sideload 3.2 full firmware.
After that reboot your phone to fastboot mode.
Unlock bootloader.
This should do it.

It's like you didn't even read what I wrote...
I said it doesn't boot to system, OnePlus logo appears for a split second and phone turns off.
Bootloader is locked and I cannot flash anything.
ADB Sideload won't read files. Gives the 'cannot read' error.
You know that you can load to bootloader by pressing volume up and power button right?

You should be fine so long as you didn't deactivate the"OEM UNLOCK " option from the developer setting....
do the following
1. press and hold the volume up an power buttons simultaneously to enter the boot loader menu.
2.select start option from the bootloader menu sorry that menu is the boot loader.
3. now connect to pc and use the "fastboot devices" command to see if your pc recognizes you op3 as an android device.
4.type "fastboot oem unlock"
5. flash the custom recovery thru fastboot
5. enter custom recovery and flash your desired rom.
hope this works for you!

And if by mistake I have deactivate the "OEM UNLOCK " what can I do?
I relocked the bootloader. Which wiped to factory reset.
That wipe deactivated the ability to unlock bootloader until reactivated from the system, which I cannot get to because the phone turns off/bootlops before loading it.
This happened quite a few times on this forum, there is really no reason to relock the bootloader on the op3, it is covered through warranty, but u will have to contact oneplus and they should walk u through and send u files to unbrick it if u r lucky

then you better get in touch with the op customer service. they will, from what i know, fix it thru a remote connection sitting.
I have no solution for you, but I wonder if you went back to stock recovery first before you relocked the bootloader? I think if you have TWRP and try to relock the bootloader, this happens. NOT that its helpful to you, but if this is the case and you can verify it, might help others avoid making the same mistake.
As far as your problem is concerned, I would look for unbricking guides. I know I saw at least one guide that lets you recreate the entire partition table manually and make it just like new for the OP2 (and has the company's blessings to do so). So it should apply here as well. Sorry, do not remember where I saw this, but must have been either on xda or the oneplus forums.

I have stock recovery. I did boot TWRP first and let it change system by mistake, but reflashed stock later. That's what might have caused the bootloop once I relocked.
So I guess if you decide to relock in the future, don't flash TWRP, cause it bootloops, even if stock is reflashed.
Bro don't worry now.
I am gonna guide you out of this.
First install an adb package like this.
http://forum.xda-developers.com/showthread.php?p=48915118#post48915118
Now get a toolkit like this.
http://forum.xda-developers.com/oneplus-3/development/toolkit-oneplus-3-toolkit-unlock-t3398799
Try to connect to fastboot and check for your device in the toolkit.
If failed then kill process adb in your task manager.
Now once connected.
Check OEM status and bootloader status.
Unlock if required.
Now.
Push twrp to your phone .
Then boot into it through the toolkit.
Now load a full ROM.
http://forum.xda-developers.com/oneplus-3/development/rom-op3lite-debloated-tweaked-fast-t3404996
Just copy paste it using your file manager on PC.
Them flash first make it boot and then root.
Hope this helped.

Nah, I think this happens only if you let TWRP modify the system partition. But, I have not and am not willing to test it out

Don't test it. I've already done it by mistake.
It replaced recovery with TWRP by allowing the modification of system and even after reflashing stock it'll bootloop on relocking recovery.
So I found something useful then.

Hello,
I usually come here to root my phone and choose the best ROM, but this time I'm here because of a problem with the official ROM. I did a simple OTA android update this weekend, and the phone never restarted. There was enough battery so nothing to report during the install. I'm stuck on an infinite bootloop and the recovery commands take me to a no command.
Beyond having lost all my data, I'm worried because no command is working. I have already followed all the tutorials on youtube (including the most improbable techniques of hitting the back of the smartphone or putting it in the freezer for 10min, I know it's stupid, but when you're desperate you try everything).
So I'm coming here to ask for your help, hoping that someone will give me a solution to at least flash a basic image and start over.
Regards

Since you can get into bootloader and it's locked, go to platform tools and unlock the bootloader. Then you can flash the factory image and proceed from there. This will wipe data.
The other image is the screen prior to entering recovery via pressing power button and vol up.
I would recommend turning on USB debugging first thing when getting any phone.
Android Flash Tool
flash.android.com
The No Command Screen is normal. You just need to press and hold the Power Button and while doing, so press and release the Volume Up key (after about 5 seconds) and then release the Power key as well. This will take you to stock recovery. From there, you could sideload the OTA package [works on a locked bootloader as well] but as already told in a post just above mine, you need to have enabled USB Debugging beforehand.
The bootloader is locked but you can access it, so go to platform tools and unlock it. After that, you can flash the factory image and carry on. It will erase all data.
To sideload an OTA in stock recovery you shouldn't need to have USB Debugging enabled. Being in sideload mode enables a very limited set of ADB commands on Pixels, including adb sideload <imagename>.zip. I'm not aware that this has changed.
To unlock your bootloader you will need to have OEM Unlocking enabled in Developer Options beforehand.
