[Q] Unlocked bootloader, need to send back to HTC - One (M8) Q&A, Help & Troubleshooting

Hi, I just have a simple question. I unlocked my boot loader using the HTC dev tool the day I got the phone. My micro usb port is broken, and my phone is under warranty, however after talking to HTC they say my phone’s boot loader is unlocked. It shows in their system. Is there any way to change that? Relocking my boot loader probably won’t help will it? They say I will not be able to get my micro usb port changed for free even though it is under warranty ($200-$320 cost). If anyone has any suggestions, thanks a lot!

[Q] Re-lock HTC One X without USB access

Hi guys,
Do anyone know how to do this as my USB seems like no reaction to data transfer and fastboot in bootloader. PC can't detect the hardware at all and i have tried on few laptops and different cable. I also tried the POGO connector but no function at all. I found this:
rootzwiki.com/topic/19864-vzwsprintgsmguide-ultimate-galaxy-nexus-guide-unlockrootflash-romsfaq/page__st__40#entry759280
but it is for Galaxy Nexus.
Do anyone face this before and i need to re-lock back to original ROM and recovery.img in order to claim the warranty on repairing the USB port.
Not sure whether is motherboard problem or the driver inside the phone corrupted by the custom ROM.
Or does anyone know how to enable back the USB by reinstall the USB driver in the phone?
Really need someone expert in Android to help me...
Thanks & Regards,
Aniki
there's no way to lock the phone without USB access, without USB you can't do anything... you should send the phone to HTC and ask for a replacement
i won't sent back because my phone is unlocked and flashed with MIUI V5 3.5.10. They said warranty is void but i already write an email to HTC Global to check what is cover when i unlock the phone. I think this is hardware failure, should not cause by software. They might erase my phone and without USB access, my phone might brick because of that. I saw many HOX user facing USB failure problem in around the world but no one solve the problem. Someone expert should look into the link that i show and come out with a way that can be done with USB access to re-lock and flash back the recovery. Android is just like a computer and there should be some way to manually flash to stock recovery and lock the oem lock.

if the problem is HW related then they should repair it... you warranty is not completely voided

Unlock Boot loader and Root

I'm new to the M8. From what I've seen to unlock the boot loader you go to HTC's website and get instructions. Is this the case? Just checking because I've never seen it done like that. Also, I have a Mac. Thanks.
I have a Mac as well. :good:

Since you have to generate a code through HTC, therefore telling them that your device has an unlocked boot loader, would there be any issues if I were to need a warranty exchange?

You should be fine if you return it back to stock and relock the bootloader.

HTC One soft bricked after update, never unlocked, never rooted, please help?

Well after almost a week of Googling, I've given up.
My Dad's HTC One M7 seems to be soft bricked (i.e. No OS), and will only enter the fastboot menu. All options therein (factory reset, fastboot), just put the device back in fastboot mode.
I then tried to unlock the device on the HTC site. I got to the final stage (flashing with unlock code, which shows as successful on my computer), and the confirmation screen on my phone does not appear. It is still showing *LOCKED*.
Moving from here the only option seemed to be an RUU, however this only seems to work with S-OFF. My S is most definitely ON. To make it S-OFF, I think I'd need to boot onto an OS and enter debug mode.
I have an OTA file for my carrier which seems to be up to date. Is there any chance this would help?
So I'm sort of chasing my tail here, any help would be appreciated. One possible solution would be if I could possibly unlock a bricked device? (A rare request from what I gather, as most phones are bricked after custom ROMs).
I find it so frustrating that this has happened when I've never even rooted/unlocked the device. I'd never seen the bootloader menu before this.
Any help would be appreciated. Thank you.
Before you do anything to trip the tampered tag, call HTC support. Our Verizon HTC ones should still be in the one year warranty. Tell them you're predicament and you should get a free replacement or repair. HTC in the US has a quick turnaround rate. When my Rezound had the dead vibrate brick issue, I got a new one back within days of shipping my old one.

You should have read the forums about this before attempting to do that. You cannot unlock VZW HTC One through htcdev. You have to use rumrunner or firewater.
Edit - you can get a warranty replacement shipped overnight, but since you pushed that code to the phone they may charge you for a tampered device.

He never said "tampered" was tripped. In the One section (the section for global and oddball variants) they have sent their phones in even after unlocking and restoring to stock, so simply pushing a code to the phone like many have before will not void warranty. In almost all cases unlocking does not trip the tampered tag. It is what you do after unlocking that trips it (custom recovery, messing with system partition, etc)

Verizon has been known to charge you if any modification has been done to the system. Even if tampered is not tripped. If you send it to HTC should be fine. Just a week or two turn around vs overnight air replacement from vzw.

Stuck at Boot. S-ON.

@4m8 since you are the only guy here who knows best about HTC Desire 300.
Well my friend gave his Desire 300 to me for repair. i thought its going to be easy as like 1,2,3. but guess i was wrong.
I tried several options already.
USB DEBUGGING might be off as well since my friend doesnt know about flashing or unlocking bootloaders. i cant unlock the bootloader i think.
Its S-ON. (Dont know what it actually means).
I tried going to recovery but it shows me a PHONE with A RED ''DOWNLOAD MODE ARROW'' i think recovery is corrupted?
i tried already flashing boot.img and recovery.img over FASTBOOT. but it says ''failed remote signature verify fail''. its just isnt like my sony device which says OKAY all the time lol. those two files were found on a Google drive website.
i have no other options left to revive this phone.
Help will be a very good option :good: thanks in advance.
Well i read a lot of sites which says stuck at boot. and i cant find a Official Stock firmware for this device. is it that HTC didnt released one?
That sounds really bad. So let's recap to see if I understand your situation correctly:
Phone doesn't boot, can't enter recovery and will only load the bootloader. (b-loader status is S-ON Locked)
Now unless you are able to unlock the bootloader (which you aren't as you have stated) there is no way to flash a custom recovery.
The locked bootloader will prevent it because it requires anything you want to flash to be signed by HTC.
The only way out is to flash an actual official update by HTC which afaik is not available for this device.
To make matters worse, if the phone is branded you couldn't even revive it this way because some providers, like mine, actually force HTC
to prevent those phones from flashing an official HTC update that is not branded.
But there is a bright side to your situation. Since you weren't able to unlock the bootloader your friends warenty should still be intact.
And even if this was a branded phone try to claim a replacement from the manufacturer, that way you might have the chance to get
an unbranded device in return for the trouble you and your friend had to endure. :fingers-crossed:
Sorry if I had to shatter the last piece of hope that you were clinging on to but without an unlocked bootloader the only option that
remains is getting a replacement or begging HTC to release an update or the version that is installed by default as a RUU exe
PS:
Just to be certain, you did try the factory reset option in the bootloader before giving up, right?

Yes i did. Factory reset. But still no luck.
Yes, i cant enter recovery as well.
Well it actually started ones it told me "Process System Not Responding". And on that point i knew the system files are corrupted.
My friend told me, he left the phone in deep sleep after that it didnt turned on again.
Thanks for your help @4m8 :laugh: :good: (IT ISNT MINE SO I DONT HAVE A PROBLEM) I will give this phone back to my friend.

M8 won't boot anymore - sometimes Bootloader and Recovery works

Hi,
i got a m8 which i unlocked via htcdev and it want to send it for warranty repair now.
The problem is that the phone won't boot!
I plug in the charger and nothing happens. After a couple of MINUTES the led shows up and the phone charges. But only sometimes.
With a little luck i can get into recovery and reinstall Viper or Leedroid ROM. But after successfuly installing the phone won't reboot and just turns off after the htc screen.
No matter what i try, it doesn't boot. But from time to time i can reach recovery.
So what can i do with in bootloader or recovery?
The biggest problem is the htc screen which is full of the red "not official release" stuff. How can i put this back to stock?
Thanks
Daniel
it would help greatly if we knew your CID and MID.
It's a unlocked non-carrier phone from germany. I think HTC_102 but i'm not absolutely sure.
Now nothing happens anymore besides the phone shows up as "Qualcomm HS-USB QDLoader 9008 (COM20)" in the device manager. When putting the Charger / Cable in the charging light flashes one time. If i put the charger just halfway in it lights up for about 2-3 seconds and turns off.

They won't take it back for warranty, because by unlocking the bootloader, you void your warranty. Your best bet is to flash RUU. Can you get the computer to recognize the phone by fastboot? Can you get the phone to boot into boot loader at all?
And also, have you made any modification prior to the incident other than unlocking bootloader?

At the moment - no. It won't even boot into bootloader. The last try is now a new battery. I opened it because HTC refuses the warranty anyway and maybe the battery is the problem. I don't think so but for 6 Euros I give it a try.

What modifications have you made to the phone prior to the incident other than unlocking the boot loader? Custom ROM, custom kernel or TWRP

This is the strange thing. I sent my m8 to HTC and they replaced the Mainboard. So the phone was completely new and stock. As the warranty was in the last days after this i immediately unlocked the bootloader officially using htcdev. Then I installed TWRP and MIUI 7 after this. Then I noticed the first time the phone was not turning on. It happened after unlocking but as I did the unlock immediately it maybe wasn't because of it. But as it is not my main phone I didn't really care and put it away. Now, about 3 months later I want to use it as my main phone for drone flying and I flashed Viper ROM and after it didn't boot LeeDroid. And now it doesn't turn on no matter what I do. Before I could manage to get into bootloader sometimes at least. I think the new main board has a defect but after 3 months, with no warranty and HTC unlocked they don't give a ****.

Yeah if you unlock the boot loader, you void your warranty

I know but I didn't make something wrong. I unlocked every bootloader of every phone and tablet I ever had so I think it's even the battery or a defective replacement Mainboard.

IDK but im going to say to try to boot into bootloader and the problem would be much easier to solve. If you manage to boot into bootloader, don't exit it and post here the 'fastboot getvar all' command on here. use this link from my google drive https://drive.google.com/file/d/0B2FyBGshXWIxeHdPRy1zWXdwM1E/view?usp=sharing to get the adb.zip if you have a windows computer. extract the zip file, go into the adb bundle folder, sdk, platform-tool press shift and right click at the same time and select open command prompt here and type in fastboot getvar all (your phone have to be in fastboot mode.in bootloader, select fastboot) and post the results here.
