HTC One Mini (M4_U4) Softbricked, OEM not unlocked, USB debug not enabled, bootloop

[olymacfoogal]

Hi all,

My HTC One Mini crashed one month after warranty (Boo!). I can get to the FASTBOOT and BOOTLOADER screen and select options. However, the Factory reset and recovery just cause a vibration and get be back to FASTBOOT menu. The phone is *** LOCKED ***.

After a few false starts on linux and mac machines, I've installed WinDroid Toolkit v3.1 on Windows 7. I have gotten the Token ID and used it to get an Unlock_code.bin via email from the HTC developers website (Cannot link as newb). However, when I follow the instructions in WinDroid it recommends that newer devices require "Enable OEM Unlock" to be set:

I cannot do this now. I continue but when it says a menu will appear on the phone, the menu does not and the phone remains in *** LOCKED *** state. I tried continuing with step 2 "Flashing a TWRP" but it does nothing.

TL;DR Am I screwed with having previously unlocked OEM on my HTC One Mini, now that it is soft-bricked?

I'm not that good at this stuff, but managed to get mine unlocked and a recovery on it via this link
sadly mine still has a problem in that it's now stuck in a boot loop, so don't use Oneclickroot as I did in my post here

hopefully you will get yours to work ok, but when you get to instruction 17 you may find that HTC website is quite fussy with the code you copy/paste
when you copy the Identifier block into Notepad or whatever, ensure you don't get any leading blank spaces before you submit it to HTC.
this excerpt from mine had blank spaces where I have inserted red X's, but it worked with them removed and HTC then emailed me the Unlock_code.bin file
XX<<<< Identifier Token Start >>>>

I hope this is of some use mate

sorry,
lost the plot on my first reply and forget about the OEM unlock bit ...

to get that OEM unlock bit you would normally
first Enable Developer Modeon your phone by Launching the Settings Application -
Scroll Down and Tap on About Phone(or About Device) - Locate the Build Number Section - Tap on the Build Number Option 7 Times -
Go Back to the Main Settings Page - Scroll Down and Tap on Developer Options and it's found there

but given that you are in is bad a place as me in that we cannot get a bootup, I'm afraid I can't offer any more info,
but it's worth knowing anyway in case you do get booted up

Hi, i have the same issue, but a little different.

My phone was in a box for like 2 months, and then i decide to turn it on again, and i faced the same problem as the OP, but my One Mini is UNLOCKED, and i can't lock it again because i get an error in ADB. I try to enter on recovery (and flashed three differents recoveries without sucess), and reboot in bootloader, then try to factory reset, and reboot bootloader again. It don't do anything, only turn on when i plug the usb and enter in bootloader but no more than that. i've try to flash a RUU too, but it give me the error 171. i tried too the method with the rubber band pressing the power button to cause a reboot loop and get enough charge to launch the system but nothing, i don't see any results. I'm one step closer to give up, please help, i tried everything and nothing has worked for me. If need more information don't doubt on asking me. I really appreciate any help you can provide.

I'll try mate ... but perhaps you are asking for help from the wrong guy! - firstly I have to say mine is still in a very bad place! -
I managed to get a permanent TWRP on it, installed a lovely rom named InsertCoin on it, rebooted, and all seemed fine, but then the battery drained rapidly and it would not charge - that issue is ongoing and I'm spending ages on it just now..

Firstly can you confirm that you can enter Bootloader and select Fastboot, and that your phone is then recognised by your PC?
ie: let me know what happens when you press power and vol down together, select fasboot, goto PC, run ADB, cable phone to PC,
then issue the command ADB devices
can you also upload a photo of your bootloader screen

i don't need to press vol down and power together, the phone enter in bootloader once you plug the usb cable. it do that alone.

This is what i get

C:\adb>adb devices
List of devices attached


C:\adb>

the phone is recognized by HTC Sync manager but i can't see it in ADB.

a few things things jump out at me ...
1. from your photo the screen is shattered! - even though I don't like being beaten by phones I would scrap it
the repair would cost more than you can get one from ebay for - about £40.00

2. "abd devices" should return you something like ... "List of devices attached sh3d7h3dj631f6a7" - when it doesn't it show a device number it's usually your drivers

3. you may think that's not it since you say that it is recognised by HTC Sync when on your PC, but I had read that HTC sync is unreliable and that the drivers are not the best
the one's I used were HTC-Mobile-USB Driver-v4.17.0.001.exe but I can't remember where I got them and will upload them later today and send you a link.
(also, it pays to plug your usb cable into a rear port on your PC when doing this kind of work as front are not as reliable)

4. your Hboot is shown as 2.22 -this also can be a problem for TWRP see this link

5. the download link he has is broken, so get any TWRP above 2.7 from their website here

Hahaha, i know, i have the replacement here, i'll change it once i solve this problem.

2. I will leave you down here exactly what i get when i type "adb devices" (with an attached image)

3. i have installed the latest HTC drivers, and i tried connecting my phone to front an rear usb ports, both of them. No results.

4. Down here i'll leave you an attached image of what i get when i try to install a recovery by typing "fastboot flash recovery recovery.img" (i changed the name to recovery.img of course) and the phone seems installing the recovery in fastboot but it gave me that error in adb and when i try to enter in recovery it reboots on bootloader.

your first image does not 'see' your device mate, so there is no point in trying a flash of anything
until you get a response from "adb devices" that shows a device number you have no chance of getting anywhere!
I am quite certain that the problem MUST be with your drivers

my advice would be to uninstall the HTC Sync and clean out any drivers on your PC and to install the drivers and flash the TWRP I mentioned earlier
sorry I didn't upload earlier as I've been very busy indeed - they are now on my Google Drive ... links here .... and here

Hello guys, I've been following this thread and I'm having same issue. Adb does not sees my phone.
Fastboot does, but when I run ruu , it disconnects and give error 171
Tried usb 2 instead of 3.nothing.
I also think it's the drivers, but I can't seem to find the correct one for this phone. Any help is appreciated
