HTCdev Error 150 - One (M8) Q&A, Help & Troubleshooting

Hello,
I tried to unlock my HTC One M8's bootloader 5-6 times yesterday, and 2 times again today via HTCdev but couldn't (already did it successfully with an other M8 so I know how to do that).
Here's the message I receive everytime :
Unlocking Bootloader Failed!
Sorry it didn't work out. Here's why:
We're sorry, but it appears your attempt to unlock the bootloader on this device has failed. This could be caused by several factors including simple errors in the entry of the unlock token, problems with your device, or a lack of manufacturer support for the unlocking process. Please see the specific error code listed below, and try again if necessary.
Error Code: 150.
Error Reason: Extract Token Information Fail.
What's the reason ? Can someone help me ?
Thanks !

Is it a Verizon phone. If so, that is the reason.

Searching around the net, it seems that not cutting & pasting the bin code exactly right is one cause for Error 150. Double and triple check you are doing it right. Although if you've already tried 7 times, I imagine that you've already checked this, or would have gotten it right at least once by now.
Is it possible the phone is a refurb, or otherwise used? One link (another device) stated you might get this error if the phone had its mainboard replaced at some point. In that case, it won't be possible to unlock the bootloader.
One other thought I had, the bin code is generated from the phone's IMEI. So if the IMEI was changed by a previous owner (such as a stolen phone), I would think it would result in an invalid bin code.

[Q] Issues unlocking bootloader Sony Xperia Arc S LT18i

Hello all,
I've got an Arc S that I've been trying to unlock the bootloader on using Sony's method, without success.
1. I have fastboot and adb installed on my machine (Linux Mint 14 32bit)
2. I've pulled the unlock code from Sony's website
3. I set my udev rules as laid out in this tutorial.
4. I have checked my bootloader to confirm that it can be unlocked (and currently is locked)
5. Fastboot is working (When I type in sudo fastboot devices, I get a hexadecimal string in response)
6. However, when I try to unlock, it always fails.
Initially, it gave me a "oem unlock failure code". After I rebooted thought, the code changed. Instead of something like this
Code:
oem unlock failed!
it gave me this
Code:
...
and did nothing. I let it sit for a few minutes and then forcibly shut down terminal, no damage done to the phone.
I'm quite confused at this point. From all my google searching I can't figure out why the booloader won't unlock. I'm pretty sure that I have the right unlock code.
A second and curious thing that may or may not be related is that the phone is rooted, but when I tried to transfer CWM via fastboot it threw an error, saying that the phone needed to be rooted first. However, it is rooted and apps such as Titanium Backup work just fine, verifying the root. Can anyone give me some direction on this?
I know there is a video on the how to unlock lt18i bootloader. It also has step by step process on fixing issues for unlocking bootloader. Lemme get.it for ya.

May be a relatively simple thing. Is your phone simlocked? This may have some bearing on it.

I don't believe that it is simlocked. I don't believe the phone was purchased through a carrier. For clarification, this is a friend's phone so I would need to ask them as to where they purchased it.

No, it is not simlocked, else it would not show Bootloader Unlock Allowed: Yes
To OP: Write out the command you used to unlock the bootloader.

As taken from the Cyanogenmod Wiki page for Anzu devices:
Code:
fastboot -i 0x0fce oem unlock 0xKEY
where KEY was the bootloader unlock I received from Sony.
The dots indicate the software's not detecting your device. I had the same problem. Try reinstalling the drivers. If it still fails, maybe you can give the method outlined in the link below a go. It's for the relatively newer Sony devices, but maybe it'd work with the Arc. I haven't personally tried unlocking via Flashtool, but for me, the Fastboot command-based experience hasn't been all too good. I now use the Fastboot option in Flashtool, as opposed to standalone Fastboot, to flash every kernel that I use. Works like a charm each time, and what's more, it does away with the need to key in commands in the exact syntax.

I tried unlocking the bootloader via Flashtool and I got the same result of
Code:
oem unlock failed!
. So that means that something is wrong with my fastboot installation (not likely)my udev rules(possible) or for some crazy reason the phone is not reporting back correctly. A curious thing I noted is that when the phone is detected via adb it doesn't return the phone's IMEI. It does return a number, but it does not match the IMEI. Has anyone ever heard of that situation?

I don't believe Fastboot returns the phone's IMEI. It's always looked to me like a random number that's generated to show successful connectivity between the device and the Fastboot program. But then again, I could be wrong.
Anways, despite the message you got, it's looking increasingly likely that your bootloader cannot be unlocked.
PS: You retired your SGS III, but kept your Arc? The decision really befuddles me.

After much research I've found that when you get the "remote: oem unlock failed!" message it means you've enter an incorrect unlock code. Thing is, I know that I have entered the IMEI correctly on Sony's website, so I'm stumped there. I tried this setup in windows and got the same result, so I don't think it's fastboot or drivers anymore. It makes me wonder why I would be getting an incorrect unlock code...
To answer your PS, this phone belongs to a friend of my whom I'm doing a favor for. Note I don't have the Arc S in my sig. My retired SIII went to my wife, who was quite happy to have it.

Are you sure that you left out the LAST number of the IMEI, when entering it on the website? You need to do that, else you get invalid code.

Yup, that I have. I originally entered the 15 digit code and the website threw an error, so I deleted the last digit to get the unlock code that I tried.
same issue as LT26ii
Well I have exactly the same issue at my Xperia SL LT26ii, it just shows "oem unlock failed", do anyone know how to fix this ?

oem unlock failed
Problem solved!
Hey guys, I just unlocked my LT26ii after many times of "oem unlock failed". Here's my solution:
0. well first just remember your IMEI code, cause later it will changed.
1. Download a new firmware in ftf format.
2. Update firmware with Flashtool.
3. Turn on your phone and get you imei code. Now you should got a new one different from the previous one.
4. Use the NEW imei to unlock your phone.
Good Luck !
PS: dont guarantee that worked but if it does please let'me know.

[Q] oem unlock fail for sony xperia arc s

Dear all :
Recently I bought an Arc S and want to unlock its bootloader, however it comes up with unlock fail. Really frustrated for that... Please give a helping hand
1. I 've tried the unlocking on three different machines Win 8 x64 Win7 x64 Win XP SP3 x86,
all showed Version 0.3 finished and oem unlock fail
2. I 've checked the IMEI code when the Arc S is on GB and ICS, both showed the same 15 digits IMEI.
3. I used the first 14 digits of my IMEI to apply the unlock Key by different explorer (IE,Firefox,Chrome), all showed the same unlock key
4. Track ID is functioning properly so I think the machine is not unlocked before
5. Bootloader Unlocked Allowed : Yes
6. Done all the methods stated in

Bootloader & SIM Unlocking:
PLEASE NOTE: The ONLY WAY to Sim Unlock your Phone is to PAY for it, so do some Googling and read which services have been recommended in the past.
PLEASE ALSO NOTE:
If you're Phone was manufactured AFTER a certain date, 12W11 (look under your battery for a similar number) then the Testpoint method no longer works, and People who have had Phones returned from a Service Centre are reporting that they can no longer unlock via the Testpoint method either.
- Know Your Android Bootloader - What it is and Why it Matters
There are three ways to Unlock yours, the Standard/Official method (For SimFree/Un-Branded Phones) which is explained HERE, (PLEASE NOTE! - You loose DRM when using the official method but not with the TestPoint) but if your Phone came from a Carrier then chances are (99%) you won't be able to use that method. There is a simple method of checking if you can or not which you'll find HERE.
Standard Unlocking:
Then there is the TestPoint method...
TestPoint Unlocking:
Two members - Alejandrissimo or Jinx13 offer a Remote Service which isn't free, but cheaper than anywhere else on the net, and when you take in to account you will also SIM Unlock and retain DRM using the Remote method it's worth it.

Mine states 12W48, but I don 't think it is branded or simlocked since I bought it from a local retailer in Hong Kong.
So even though it says Bootloader Unlocker allowed : Yes still might have chance that It is simlocked?
You should be able to unlock by the official method, which you wrote about.
You said it showed "oem unlock fail". What's the full error given in the log?
Guess I found the answer.
I think this is a refurbished Arc S and the IMEI code is a fake one.... "awesome" china goods....
Any method to unlock the phone given that YOU DON 'T KNOW your true imei?
Under the battery or in Dialer *#06#.
You don't get my meaning....
What I mean fake code is that
1. The IMEI stored in the phone
2. The IMEI stated in the sticker and box
are ALL FAKE.
I found that there are a lot of similar cases in some other Chinese Androids. They figured out the reason behind that is the IMEI code is modified by retailers (Well I don 't know how can they do it, but it seems very easy to them) and the IMEI you extracted by all means from the machine is no longer the original one...
Any method to unlock the phone given that YOU WILL NEVER KNOW your true IMEI?

Yes,
you can use test-point method to unlock which requires no IMEI number.
Oh boy..... What is going on....
Wait a second. This makes no sense. Firmware reports one IMEI, but phone is actually using a different one? How do you even use it then?
That 's why those chinese refurbished "brand new phone" are so awesome...
They claim that the phone is brand new and the evidence is that the IMEI stated in the phone , the box , the sticker are the same. However you use that that IMEI to unlock the phone and eventually fail. The only reason is that this is a refurbished one and those IMEI are fake.... There are numerous cases in the Chinese Android Forums.... You even can not unlock it by brute force (test point method)....
In that case we are not talking about Xperia Arc, but a chinese copy of this phone. Thereby this method does not work for you.
Sent from my LT18i
No. The machine itself is ORIGINAL, you can do a official update and apply the original ftf. The retailers received those second-hand goods and then INSERT A NEW IMEI and forge those stickers for the box and the machine so that the retailers can claim that it is brand new. I searched in the forum and found that some retailers will insert the same IMEI in to a batch of refurbished phone =.=
There are numerous methods for unlocking the phone but all resort to the IMEI, what if you have a fake IMEI =.=

Your Device Has Failed Verification And May Not Work Properly

I recently got a 7x from ebay.co.uk. I noticed the opened box states the model is BND-AL10 (Chinese) but in the phone settings it's a BND-L21 (International). S/N and IMEI match.
Out of curiosity I tried Huawei Firmware Finder for Oreo. I used DNS method, picked the top one as seen here (verified): hxxp://pro-teammt.ru/firmware-database/?firmware_model=BND-L21C432&firmware_page=0
It downloaded like 20 patches totalling around 8+GB and then asked to reboot...and failed.
My phone still works but I now get this during boot:
"your device has failed verification and may not work properly.
1) Press power key to continue.
2) Press volume up key up to 3 seconds to enter erecovery to restore your device.
3) your device will stop,start if there is not operation.
I tried Huawei eRecovery: 'Getting package info failed'
What should I do? Noob.

erecovey fails for everybody. dont know why.
the message you see is normal if bootloader is unlocked. You should have had that same message first time you turned it on too.
Attempting to use firmware finder to apply updates , is not possible to unlock bootloader, so it had to have already been that way.

This is known message resulting from of having boooader unlocked. Few people have been trying to make it not show , but no one has made it public if they have been successful at hiding it.
Now you got that phone (used, I assume ).From eBay. Perhaps the previous owner found some way. And attempting to update made his "hack" undo. Don't really know.
You can check if bootloader lock status to be sure if it is unlocked or not.

I read that "Huawei is no longer offering bootloader unlock code in 60 days." I tried to request a unlock but I get just get
"If you have any questions about the unlock code application, please contact us."
Nothing happens. I contacted them.
Will I ever need that unlock code given that it is already unlocked? Should I return/refund the phone and buy from Amazon UK or am I wasting my time, since I'll likely be requesting a unlock code and possibly be playing with roms in a few years. I keep phones as long as possible and a basic user which is why I have little knowledge with them.

I would try and get a refund (if you bought via PayPal I think you may get some kind of support).
You can get the 7x from UK retailers for as low as £210. But the current Amazon price of £228 is not bad.

The unlock company who I went through apparently changed the Model number to a Moto G4, but the unlock seems to have stuck, but the model number is different. At this point, I've gotten ATT to give me an official sim unlock code. So I'm really not sure what to do.

Is anyone having trouble unlocking the bootloader on the european version? (LMG710EM)

hi, so I was trying to unlock the bootloader before attempting to use an AOSP pie rom using this guide on the official LG site http://developer.lge.com/resource/mobile/RetrieveBootloader.dev
Anyway when I come to step 9, I type "adb reboot bootloader" and the phone reboots in fastboot mode. Then when I type "fastboot oem device-id" the phone freezes and I have to press the power button to restart it, meanwhile in the powershell command page it says
Code:
C:\Users\chahi\AppData\Local\Android\Sdk\platform-tools>fastboot oem device-id
FAILED (Write to device failed (No such file or directory))
fastboot: error: Command failed
I checked my drivers and everything seems to work perfectly fine. I am at my fifth attempt and I'm beginning to feel pretty desperate. If anyone encountered the same problem or could help me solve this I will be very thankful !
Thanks in advance.
NB : I'm on windows 10 and my phone is running the korean pie rom.

NB : I'm on windows 10 and my phone is running the korean pie rom.

I cannot 100% say what the cause is with certainty (I have the Sprint version and I absolutely hate this piece of trash) but others have reported similar issues from actually having a different variant that was cross-flashed to the EM model and sold as EM when it's really a Sprint version (for example). What happens when you enter your IMEI number in LG site, does it return the EM variant or something else? That's where I would start (unless you have already done this and confirmed it's EM). Non EM versions lack the full ADB support so we can't unlock the bootloader. This is the same point I lockup as well but mine was not intended to be unlocked.

Thank you for the quick response !
Yes I actually typed my IMEI in the LG site and it gave me a gray OK so I guess I truly have the EM version ? (knowing that only the EM is supported idk) Are there other methods to make sure I have the EM version for sure ? Also worth noting that I bought the phone new from North Africa so it must be the european version and not a carrier one.
Thank you !

Not that I'm aware of but if the LGdev site let you get the unlock code then I will assume it's real as they do validate it. Normally I would suggest to reach out to LG but that's a waste, they won't help. In fact they shutdown the dev recently because of unlock requests so they don't care about us so that won't help you. I'll do some research and see if there's any official way to help but hopefully others will chime in with the answers.

That's what I actually did, I sent them an email but I'm still without any response. Thank you for your help tho ! Is there any unofficial way to unlock the bootloader on the LG G7 that I'm unaware of ?

Good luck with LG, they most likely will do nothing to assist you. That's my biggest gripe with LG, they suck with customer care nor give 2 craps about us, the customers. My LGG7 sucks so bad, it's barely usable but they will not do anything to help me nor Sprint so I'm leaving both once my horrible lease is up. All I can say is to sign the bootloader petition and leave LG, it's the only way they will ever change and even then, they probably won't. They will soon be out of business just like Blackberry's downfall and for the same reasons. They don't listen to the customers and change, nor did RIM with activesync, now RIM is a mere fraction of what they used to be, LG mobile is next. I hear so many complaints about LG devices, not just LG mobile but the entire company. All the same type of complaints across all LG products, no customer support when the device stops working and they pass the buck every time, and locked bootloaders (for LG mobile).
There is no unofficial unlock yet, that's why I'm so unhappy with the piece of junk! If I could unlock and install my own flavor of AOSP then it would be an entirely different story and I would fix my own issues and have an awesome device. Instead the jackalope in charge of LG decided to keep the bootloaders locked with no support to unlock (except for EM) but even that barely works (your issue).
I don't know what else to say except LG SUCKS, LG is terrible. I so wish I hadn't let the Sprint rep bully me into this horrific device. I should have stood my ground and not accepted the deal which came with this expensive paperweight (LGG7).

SIM unlocked, yes, bootloader unlocked, no (on Sprint and everything other than the European model, no, EM model, yes), the rest of us, no, huge difference. I would pay a small fortune if bootloader unlocks were possible and why I bought the LG octoplus, still no option yet unfortunately.

I don't know from where exactly. You have to find it yourself but eBay is a place to start.

Are you 100% sure this is not SIM unlocked using a modified octoplus (I have already gone down this path) so I bought my own octoplus. I am pretty sure all these "unlock" are merely SIM unlocks and not bootloader unlocks. I've investigated this pretty deep and it was only SIM unlocks not bootloader. As far as I'm aware, there is no hacks or mods to unlock the bootloaders for any LG G7 as of yet. eBay results are all SIM (which is simply using oct to apply the US-unkocked m ok model unlocking the SIM).
If you can find a REAL bootloader unlock method that works and unlocks my bootloader, I will PayPal you 20-30 bucks (I'm not joking). There is no method yet that anyone I know, knows of.

It's not sim unlock
It works by installing g710em bootloader and then flashing an unlock.bin .It's actual bootloader unlock. You can probably even do it yourself on a octopus box but I'm not sure what does it allow and not allow you to do.

Fantastic then I will investigate this new theory and if it works, reply to everyone. I've been waiting for this since day 1 with this terrible G7, I HATE this device and OS.

If does exist, I can't find it on eBay or the internet, only SIM unlocks. I will keep checking but I don't see anything to unlock the G7 bootloaders.

I can send you abl_a and you just need to use my unlock.bin to unlock
Edit: can I send it to you privately so nothing personal leaks?

hi, so I was trying to unlock the bootloader before attempting to use an AOSP pie rom using this guide on the official LG site http://developer.lge.com/resource/mobile/RetrieveBootloader.dev
Anyway when I come to step 9, I type "adb reboot bootloader" and the phone reboots in fastboot mode. Then when I type "fastboot oem device-id" the phone freezes and I have to press the power button to restart it, meanwhile in the powershell command page it says
Code:
C:\Users\chahi\AppData\Local\Android\Sdk\platform-tools>fastboot oem device-id
FAILED (Write to device failed (No such file or directory))
fastboot: error: Command failed
I checked my drivers and everything seems to work perfectly fine. I am at my fifth attempt and I'm beginning to feel pretty desperate. If anyone encountered the same problem or could help me solve this I will be very thankful !
Thanks in advance.
NB : I'm on windows 10 and my phone is running the korean pie rom.

Hey Piatch, i'm stuck on your same situation!
I have a new LMG710EM taken a month ago in a store, today with the Pie release (I'm in Italy) I found some time to unlock the bootloader, root, debrand (my G7 is TIM branded) and update to Pie.
I'm not new with LG, I come from G2, G5, G6 and now G7, never a problem (apart from the slowness in the updates I like them).
Well, just your situation, only the wording is a bit different, to me it says FAILED (Write to device failed (Too many links)) then the phone reboots and freezes in G7 logo and I have to press the power button to restart it, like yours.
I've tried everything, even reading online, different USB cables, different fastboot versions, but nothing worked.
Then I unbranded via lgup refurbish option to have a clean install and reinstalled all, thinking that maybe the new OS would solve but nothing, same message.
Can anyone help us?
It is the first time in several years that I have not found a solution.
Thank you in advance

Hi f0ster, I did not find any solution because I was lacking the time and tbh the skill to do it. I think we can't unlock the bootloader while under Pie ? Maybe if we roll back to Oreo, then we can unlock it and then update to Pie again ? I don't have the skills nor the confidence to safely flash Oreo on the G7 (I had bad experiences with bootlooping on the G3 and G4). Maybe you could try this way and see if it works out for you ?
