If you were not on full stock rom without root, or anything custom, and you turned off OEM unlocking and USB debugging, then locked the bootloader, you are basically hosed my friend

Look at this point it just needs to be said... PEOPLE STOP RE-LOCKING THE DARN BOOTLOADER!!
PERIOD!!
There are literally a half dozen posts this week with probably bricked phones and a good amount of them are this same root cause.

Your preaching to the choir ol friend! While I agree with you 100%, some things are best learned the hard, and expensive way! I've done it twice myself.
The carpenters rule should apply to these phones as well...."measure twice, cut once" :good:

I remember and I'm sure that i left USB debugging enabled, and the bootloader locked, so is there any hope ?

My friend.....you could give me or anybody else 10 thousand bucks, and it's still not going to solve your problem I'm sorry to say. You should have unrooted the phone first, then fastbooted the factory image, or do a factory reset, and made sure that OEM unlocking & USB debugging were left on until you were done locking the bootloader. Sorry man, but there's not much you can do without at least a stock recovery, so....accept the loss, learn from your mistake, and move on. Many of us here, including myself, have been there as well. What you choose to learn from it is up to you

[Q] Warranty question

Hi
I have a question before sending my HTC back for the wifi repair to HTC.
If I make a nandroid backup of my existing custom rom, then unroot the phone, when I reroot the phone once i get it back, can I simply use the nandroid backup I had made to restore everything once I have re-rooted?
Thanks
Manny

Yep, ofcourse you can.
To be honest you need to re-lock your bootloader also.
And hopefully your lucky enough to be one of the people that gets a warranty fix even though your unlocked and rooted.
As many people get turned away.

Ok, thanks, its worth a try
I made a nandroid backup of my stock rom and also have the boot.img for the stock rom. I assume that if I flash these 2 first and then lock the bootloader? Is that correct?
if it is correct - is it simple to lock the bootloader?

Hi, yeah thats correct mate.
Easiest way is to flash the correct RUU for you phone. Im sorry but I don't know how to get the correct RUU perhaps someone else could help.
What I do know is that you can never fully "lock" the bootloader again, it will say "Re-Locked" and not "Locked" all you can do is hope they do not check the bootloader.
Hope this helps

If they check it and see it says relocked and then refuse to repair it is the same as me leaving it unlocked?? So i may as well leave it as it is?

But definately return it to stock as much as poss, using the RUU or flashing the stock images etc.

ok cool, in that case will just flash the nandroid back up of the stock img and the boot.img and leaver the bootloader unlocked - should be sufficient. should i also uninstall the clockwork mod etc?

Definately, if they boot the phone and see CWM, TWRP, Titanium, SuperSU/SuperUSer they'll know straight away you are rooted.
Remove anything you possibly can that will identify a rooted unit.

Using their repair tracking page, the current status is "in repair" so it's looking good. The status just changed an hour ago though so there's still plenty of time for them to call with bad news.

Warranty VOID?
I needed to send my phone in, but I don't have the sticker on the back, or the box, and there's no way for me to get to the settings on the phone, because the screen stopped working.
Will HTC still be able to service my phone, or is the warranty considered void?

HTC repair is bull**** just for the record. I have 4G Slides on the rest of my lines, ALL of which had to be sent in.
2 of those phones took nearly 45 [FORTY FIVE] days to get back to me. Apparently there was a hold for parts coming in from Taiwan. They wouldn't tell me which parts. They wouldn't even give me an estimate time. HTC didn't apologize or update me on my repair. I found all this out after numerous calls day after day.
But if you thought that was bad service, you'll love this...
The third phone was sent out and came back fairly quickly. Within a week. I was so happy to get my phone back.
Opened the box and GUESS WHAT?
HTC SENT ME THE WRONG PHONE
They sent me a completely different phone for a different carrier (HTC Evo 4G for Sprint). It was very beat up as well.
I swear, if it wasn't for their designs (which I love dearly) I would've dropped the company by now...
Sorry for the rant/threadjack. Thought you guys would like to hear a horror story. I'm done
does anyone know how to remove the super su app and the clockwork recovery? everything else is now back to stock as i did a nandroid back up immediately after rooting initially
thanks

Yes, but going back to s-on after all the modding you've done is dangerous. If you don't do it right, you can easily brick your phone. I would leave it alone if you're just trying to get rid of that text. Not worth the risk IMO.

Damn...just made a huge mistake. phone bricked?

My son wanted to root his brand new phone. i have rooted 8 phones from different phones before with success..... but this time i f***d up...
Accedently installed this on his phone.
http://wccftech.com/flash-and-root-nexus-5-on-android-6-0-1-mmb29k/
executed flash-all.bat and it flashed the bootloader.
For the wrong phone...
It should have been this one..
http://wccftech.com/flash-and-root-nexus-5x-android-6-0-1/
Missed the X......
Now the phone will not even boot any more at all....cant enter bootloader.......does not power up at all.!!!
Jesus...what have i done.......
It here any chance at all to fix this somehow?
Hello and thank you for using Q/A,
because you can't enter bootloader, you can't do anything. You can try to send the phone to Google. Say: It didn't boot after OTA Update.
Kind regards

Yeah it's most likely a paperweight. Try sending it to Google. Flashing the wrong firmware destroys a phone as you probably already know

but somehow one must be able to flash the bootloader from scratch....
Normally via special software etc.

Only thing I know to use is a riff box to jtag it. Not sure if they have one for 5x.

Your use of the period seems rather condescending. And no, you as the end user cannot fix that. You did one of the few things that is unrecoverable unless you manage to get the bootloader to accept adb commands somehow.

Well. the bootloader is flashed into the phone from the beginning aswell during manufacturing. I work with electronics and software and i know there is always a way to reflash the bootloader. All the electronics comes in the beginning with no software at all, one only needs the proper software/hardware. Most probably by jtag....or if they have some other special tool for snapdragon 808.
Stupid of me not to see that the version i flashed was not for nexus 5X...and only for nexus 5

Good luck. Will Google not rma it?

Pixel 2xl Can't Find Valid Operating System.

I've tried to lock the bootloader. But after locking the bootloader the phone restarts and shows the message that Can't Find Valid Operating System.
In FastBoot Mode it shows:
Secure Boot -Yes
Device State - Locked
My Bootloader Version - TMZ20k
Baseband Version - g8998-00253-1809191716
What's the solution?
Hope you didn't try to lock the bootloader without being fully stock...
If so, you've just bricked your phone.
If you're fully stock, you can bootloader unlock the phone again and start over.

does your computer recognize your phone?
if so make sure you have up to date adb/fastboot
boot into bootloader then open command prompt
type fastboot flashing_unlock
why did you relock your bootloader?
maybe try deuce's script or the all in one tool. They're pretty handy

Or any of the other 100s of stickies that the vast majority never read?
Those stickies?
I'm actually AMAZED at the "right now, immediate gratification" mentality of so many people nowadays.
I have this $800+ device, I want to customize it, what should I do first?
1) read the OPs and research the guides for my device PRIOR to messing with it,
or
2) skip all the research and OPs and flash my new device the way I flashed my Note 3 from five years ago?
Who in their ever loving right mind picks 2??????
