HTC unlock gives error

HI, a week or so ago I updated my HTC sensation with an OTA update, but lost my Wifi.
I check some of the treads and tried various suggestions in them but still no joy.
I contacted HTC UK and after trying several things , including factory reset I was asked to return the handset.
To day a received my handset back., Wifi now works, software is 3.33.401.106, which gave me the Wifi problem OTA. Serial is same IMEI is different (New mother board?)
h-boot is 1.29.0000 (was 1.27.0000)
I attempted to use the HTC all in one kit to both unlock the bootloader and re root the device, which worked fine on 1.27.0000.
however the unlock failed, so I then followed the bootloader unlock steps on the HTC site and again no joy.
Token subittal is sucessful but .bin file gives the following
c:\AndroidSDK\platform-tools>fastboot flash unlocktoken unlock_code.bin
sending 'unlocktoken' (0 KB)...
OKAY [ 0.156s]
writing 'unlocktoken'...
FAILED (remote: unlock token check failed)
finished. total time: 0.172s
Any suggestions/help appreciated

You cant unlock it with with HTC dev after the Mainboard replacement , you can still soff and root using this guide: http://forum.xda-developers.com/showthread.php?t=1661631

Edit: (Link added). Afaik you cant Unlock using HTC Dev because you SN and IMEI doesnt match anymore.

Thanks for this, tried as per instructions but the ControlBear.exe task had problems, never connected to the device, so never got to the 'wire trick'
Will check thru the tread for this method and see if any problems listed

make sure you met the per-requisites mentioned in the thread..mainly un-install HTC-SYNC and dont use any usb hubs,3.0 ports ..and if using PC ..connect to the back ports of the device

Stuck in Bootloader

Hi apologies if been asked many times but going to ask again.
My sons HTC One Mini is looping on the bootloader.
Cannot do a factory reset either, any options just loop back.
I spoke to HTC who said I could send back but if there was any damage they would charge.
Its got a couple of cracks in the plastic casing so guess thats enough for them to charge.
Before I decide is there anything I can do to sort myself without invalidating any warranty etc? (its still under contract)
Thanks in advance

unlocking bootloader "will" void Warranty, but here are some ways to get back to a clean state.
But the easiest and safest thing would be to apply a RUU if you can find one for your device.
Try "HTC One Mini - Stock ROM wiederherstellen via RUU" in google, it is in German.

Phone contract is with EE, Closest thing I can find is an Orange download it has the same version number 4.15.61.1, is this the same?
Went to http://www.htcdev.com/devcenter/downloads

Your bootloader is locked in that image. Did you ever unlock it? If the answer is no, then you should be good to go as far as warranty.
As for the cracks, if they're the hairline ones that appear on the sides, you shouldn't have any issues. That's a known problem with this phone. HTC will probably just swap the phone out because of them.

I am having the same problem, only mine is out of warranty.
i have a video of what it does, i can't run any ruu
since i can't post any vids search youtube " HTC ONE MINI NO BOOT
Part one
Part Two
any help would be great, Thanks

SO NOTHING ?????????????

put your phone to ruu mode and try manually flash the zip you get from the executed ruu out of the temporary directory.
you tube video "Flash an HTC firmware zip" this might work not sure with s-on, you can also unlock your bootloader and install a recovery and custom rom

[Completed] Rooting problems htc evo 3d x515m gsm

Hello guys. First to mention that maybe my English is bad since i'm form Serbia. I've tried to unlock bootloader, "How to Root HTC Evo 3D GSM!" on HTCEVOHACKS
To downgrade hboot from 1.53.0007 to 1.49.0007 and to s-off "How to Downgrade to HBOOT 1.49.0007 on HTC Evo 3D GSM!" on HTCEVOHACKS
I did every single thing that needed to be done, with first method, i got stuck on this
"sending 'unlocktoken' (0 KB)...
OKAY [ 0.144s]
writing 'unlocktoken'...
FAILED (remote: unlock token check failed)
finished. total time: 0.157s", and then i've tried solution with RUU.exe, i think i found right one for my phone, finished rooting successfully, and i've tried again to unlock bootloader, but bum, the same thing with command prompt fails to write unlocktoken. With second method for downgrading i have changed CID as it says to HTC__001 i think, but on next steps i had no luck, it just finishes all work with command prompt, but on phone won't show that it's installing rom as on the video, just shows htc logo and then just boots up to android, hboot still 1.53 and S-on.

I think I bricked my phone. Can't find a fix

I recently got this phone and found out it was an EU version. I unlocked the bootloader and installed twrp. I made the major mistake of thinking I needed to relock the bootloader to install a ruu file. I can't get to recovery now to factory reset. If I try to reboot, it goes to an encryption screen that I can't get past. So I can't go to settings and turn the unlock bootloader option on or debugging. So, I can't unlock the bootloader either.
I also made the mistake of changing the cid and mid to USA dev. The cid and mid are: BS_US001 and 2PZC50000. The product: htc_ocnuhl.
The US unlocked RUUs should work, right? Well, I try to use the. exe. It won't work. I try to do the fastboot way, it says the file size is too large. I try the SD card way, it says 19 RU_MAIN_VER_FAIL is version in android info missing or i.
Am I just totally screwed?

This is a shot in the dark but trying reflashing your unlocker token you received from HTC and see if that will reunlock your phone so you can refresh recovery

Won't let me. Can't get into the os to turn the oem unlock on in developer's settings. When I try it, it tells me:
Last Byte is 0x00, disable unlock.
oem unlock Turn Off!

Have you tried the proper htc_fastboot.exe?. You can find it easily on the forum. If that doesn't work can you get to download mode and change the cid and mid back to original?

Yeah, I've tried it. I've tried it with trying to get twrp to boot with, "fastboot boot twrp.img". No go there. I haven't tried to change the cid or mid back, but since I'm S-on now, I doubt I'll get very far. Temporary s-on. Just great. HTC really screwed me by making these changes. Four generations of phones work the same freaking way, but this one just had to be different.

Looked a bit on the forums and 19 ru_main_ver_fail can apparently mean wrong cid? Did you use the US ruu for the SD card method? Try the other (either your original cid or the US one) and see what happens?
EDIT: Also the output of fastboot getvar all would be helpful to debug

Yeah, I used the US ruu after changing the cid and mid for the US dev version. RUU_OCEAN_WHL_O80_SENSE90GP_MR_NA_Gen_Unlock_2.42.617.7.exe.
Tried 2.42.617.1 8 via sd card. RU_SIGNATURE_FAIL
I tried a few others too. No dice. Said wrong OS. I tried the one that came with the phone using the sd card, the EU version, 2.33.401.10, and it says RU_MODELID_FAIL modelid in android-info mismatched
This wouldn't be a problem if I was S-Off. The OS version on the phone now is 2.33.401.10. If I could change the cid and mid back, it would probably work.
I tried using HTC fastboot:

When in download mode u can flash install twrp recovery via adb then possibly flash a backup file, which hopefully u have or can get,,, or a rom. I have done this many times with a failed ruu install and it has worked.

Oh dear I think I see the issue. I don't see any RUUs for the US cid/mid that match the model htc_ocnuhl. I think you can only install an RUU that matches all three and it won't let you install a modified one because the signing will break
And now you can't get into s-off to change it again because the BL is locked. This looks bad...
There should be a warning somewhere about changing to cids your model doesn't support

Great. In past HTC phones, changing the cid and mid was enough. Now there's a third factor. Can you even change the model with s-off to install an official US RUU on a EU U11? Regardless, I'm stuck between a rock and a hard place. I had no idea that relocking the bootloader would block any chance to load twrp. That wasn't the case on the past phones and now I can't even do a factory reset.
All I need to do is get into the OS to switch bootloader unlocking on. (why they did this to make it more tedious, I don't know.)
The biggest reason I've stuck with HTC is because of how easy it used to be to change regions and install any RUU.
I still get the 155 unknown error when using a RUU.exe. I'm guessing that's why.

The htc_* monikers seem to denote different hardware revisions. So probably different radios, partition layouts etc. You might have been able to change to EU unlocked but it probably can't figure out what to do with US firmware at all. Changing to super cid may have been a better option. This is genuinely a sucky situation though. Maybe there's a way out I don't know. Sorry about that.
EDIT: Are you sure you don't know the encryption password? Did you ever set one?

Thanks for trying to help. I can't see a way out either. I never set a password for that. I did for the lock screen but said no when it asked me if I wanted to use it upon boot. Besides that, I'm pretty sure it factory reset when I unlocked the bootloader. Wish I hadn't locked it right after. ?

One last resort. If it factory reset after unlock it might have a default password. I can vaguely remember something like that existing but can't seem to find it anywhere.

Found it. Try "default_password". Otherwise I'm out of ideas.

You can try" fastboot format userdata" .
You should be able to enter the system without password.
But You will lost all data(Include Internal storage)

I'm fine with losing any data. New phone and there's nothing I need to save on it. I just need to be able to access the OS so I can unlock the bootloader. I'll give it a shot.

I've been following your thread and was hoping it would have led me to a solution to my own dilemma that is similar to your predicament. I had a U11 that I unlocked via HTC Dev website and I wanted to "relock" to get the OTA update. I used a ADB command to relock the phone and the phone boots to a encryption screen which of course won't allow me to bypass. I spent hours looking for a IMG and RUU file that would get my phone back to working order. Used the SD card and ADB process and could not find any joy.
I just sent my phone to the HTC service department. I am hoping they won't make me pay dearly for my mistake. Good luck in resolving this issue. I just got my phone in April and now I am using my old M8 that won't hold a charge for 4 hours.
Live and learn.

Well, I think I know why the RUU.exe isn't working and I got the 155 unknown error. The os doesn't match. I'm guessing the os region needs to be the same, too, and since I can't seem to delete or format the os without unlocking the bootloader, the RUU won't work. [emoji58]

Yeah, I wish this could have been more help for you, too. I just can't see a way out of it. I even tried changing the cid and mid in the firmware folder I downloaded from htcdev and flashing that. No joy.

Yep, I tried all what you have done. No dice. Snake eyes. I was hoping to find the exact RUU version for my phone (2.42.617.6) but the I only could find the latest version which is on the HTCDev website. I am not able to get into recovery mode as the phone will give me the message that the phone is loaded with a different OS that it was originally installed. Dead end.
So after trying for over a week the same old steps and reading as much as I could on this and other websites, I knew there was no way I could figure this out or at the very least the phone was in a state beyond my abilities to repair. So my last resort was send it back to HTC. When I first was confronted with this issue I contacted HTC via chat. They were with me for an hour and a half explaining about getting into recovery mode and I explaining what was happening on the phone as we went into download mode and trying to get into recovery mode. Plus my typing skills isn't really proficient so it took time for me to compose and type. Ha! This initial contact with HTC and the start of the service process was on 1 September 2018. I have two weeks from the initial start of the process to send the phone back or I would have to initiate the process again. So this Monday I sent the phone in. The phone should be arriving in the Texas office tomorrow.
I posted this question on another thread and I'll just throw this out here also. If any member here knows or have had experience with HTC service department, what process do they go through to get the phone back to the original working order? Do they reflash the phone or do they actually need to physically replace a part in the phone to get it working again? My phone is still under warranty but I think bricking the phone is not covered even under their "Uh Oh" warranty. Any idea of the cost of repair? Aloha and mahalo.

HTC u12+ stuck in bootloader

Hi there I have played with my U12 dual sim and I did change cid and mid almost same way like in HTC u11+ forum https://forum.xda-developers.com/htc-u11/development/to-modify-cid-mid-s-devices-t3771570 then I installed stock system vendor and boot for us unlocked everything goes well until system could not read sim card so I have tried go back to stock same way

I had basically the same error message as you. I couldn't find a resolution so it went back to HTC repair last week. Good luck in figuring out and resolving the issue.

I didn't get a repair quote as of yet. I sent it in and they had received it last week Thursday and now it is in the repair queue when last checked. I've heard of horror stories about customer service and the repair department. Some members says their phones were not returned to them for months. When I chatted with the HTC rep on their website, the rep said it could cost up to $200 to repair (it is a HTC U11 unlocked version). So in the meantime, I am using my old HTC 10 which doesn't hold a charge and I ordered a new HTC 12+.
I should have done more research and figured out what I should have done correctly before trying to relock the phone. Live and learn.
Good luck.

I didn't get a repair quote as of yet. I sent it in and they had received it last week Thursday and now it is in the repair queue when last checked. I've heard of horror stories about customer service and the repair department. Some members says their phones were returned to them for months.

I just had a reply from another member on the forum regarding his phone repair (HTC U11). He is in Sweden and it took less than a couple weeks for him to get his phone back from HTC repair center. The repair center is located in Poland and he had the phone repaired (motherboard replace) at no charge! Wow!
I would contact your HTC repair center if after all is said and done doesn't resolve your phone issues. You may be happy you did. Hoping for the best.

I had the same issue too, but if you were able to boot into fastboot you theoretically could still get the phone to boot. were any of you able to boot into download mode? if so you could have ./fastboot format userdata, ./fastboot erase boot, ./fastboot erase system. Then done a ./fastboot getvar all and see what slot you were on. With A/B partitions its important to have a boot img. and a system img. luckily I had both and in download mode I was able to ./fastboot flash the boot image then ./fastboot flash the system img to the current slot the phone was on. I was on slot b so I ./fastboot flash system_b <system img>. I did get a magi error when flashing with power shell but it did go through and crisis averted. It is very important you back up things as well as have extra images handy.

Hi there this is my second account
Yes I did try all of fastboot commends but with no luck as download mode is needed
I can't boot in to download or recovery whenever I try it reboot back to bootloader
I did try boot twrp boot I goes in to black screen
I have European dual sim but I converter to US one I have US ruu. Exe but won't work as my battery is below 30% I did charged with that bat file that allow you to charge phone while is restarting but still not enough my phone is charded to about 4320mV any one have idea what's it should be
Phone bootloader is unlocked but s-on
Thanks for any advice

It seems like there could be so much that could go wrong when trying to tweak these new phones now. It isn't straight forward as it was a few years ago. I've read through the guides on these forums but it seems like there is no straight forward positively fool proof and bullet proof method of rooting and reverting back to stock on these new phones.

You weren't able to access download mode? Mine would boot up then go to where you can select Reboot, power down, reboot download,reboot recovery, ect. Is that something still accessible?

Might want to convert it back to European dual sim. If you can find an RUU for it, captain throwback has a program that converts RUU to system img., boot img.

Yes I can choose all option in bootloader but will restart back to bootloader screen
I can't boot download mode or recovery I can't power down unless I disconnect USB cable
Ive booked repair with HTC but still wait if someone got any idea how to resolve it
I don't think any img file will help as I can't boot twrp or flash anything with fastboot
I can boot twrp but it goes black screen only
I can flash hosd with fastboot but that's all
Can any one run fastboot getvar battery-voltage and let me know what's mV is above 30% I got us ruu. Exe but won't flash because battery level
My battery shows around 4270mV at the minut
Thanks

guys, has anyone figured out this?
i'm stuck on the bootloader page, when i choose download or recovery it restat to bootloader again, flashed hosd from fastboot but no good!
i hope some one has any resolution, as we don't have htc service center here in middle east.

Same Probleme here, I've tried everything. I've never had such problems before. Working on this for months now. Here is the Thread I opened: https://forum.xda-developers.com/t/...mode-partition-failure.4197203/#post-84031727
What I can say so far:
We need a possibility to flash and repair boot partitions without DownloadMode, HTC has special cables which go into the MicroSD-Slot to connect the internal NandFlash to USB
I've bought XTC2Clip, but haven't found a working solution yet
On most phones there is a possibilty to get QPST running, if we would find one for the U12+ we might be lucky
I don't know any german oder english speaking forum with new informations, believe me I tried, BUT there might be forum in taiwanese, there is still a huge fanbase for htc, but I'm not able to search in this forums because of the different signs
I wish us both luck,
Greetings

i had same error and now waiting a resoluation from anyone ...........
anyone help me !!!

I'm still working on it, no solution so far. But what I know today is the following:
- the boot-partition is bricked, so if we try to boot downloadmode or to boot twrp.img, bootloader doesn't know where to put it. You could say the partition-layout isn't correct anymore
- it would be easy to repair, if we had acces. I've a complete emmc-dump from another U12+ here, with adb-shell you can restore complete partitions
- when htc produced this phone, there must have been a way to write these partitions for the first time, for other models there are deep-flash-cables and stuff, but the interest in the U12+ isn't that big anymore, so there is no solution so far
- don't buy XTC2Clip, it once was THE THING for htc models, but nothing works on our device anymore, if you still wan't one, I've one to sell
Nevertheless, have a nice day

Have you tried to enter RUU mode with htc-fastboot.exe?

Hey,
yes I tried this as well. Doesn't work either. But thanks
Grateful for every idea.
