How to change the bootloader code? - P8lite Q&A, Help & Troubleshooting

Hallo everyone,
to unlock the bootloader on the P8 lite is a individual code necessary and I'm asking me, if is possible to change the code. Has everyone information about the encryption methods of the Stock bootloader? I'm currently waiting for my code to unlock the bootloader and root the device.
Thanks and best regards,
Pucciano

We mentioned a few times before, you don't have to wait for the response. I sent my email to them about 1 month ago, still no reply.
This is only works for the ALE-L21 model, by the way:
Get this program, and extract it somwehere, then open it.
In the program, select HUAWEI C8812 and enter your IMEI. It'll give you a Product ID. Copy that ID.
Now open this site, and fill it out:
-Type: Smart Phone
-Model: HUAWEI C8812
-Serial: Settings->About phone->Status scroll to bottom.
-IMEI: Settings->About phone->Status scroll to bottom.
-Product ID: the one, you've generated a moment ago.
-Verification code: as shown on the picture.
Thats it. You should get your code instantly, if your press Submit.

I know, but for the online tool is a mobile Account necessery and don't work with an email regretted Huawei ID. And only a couple of Asia country's ar supported. I try some free SMS receive services but there numbers are consumed (only two codes in 6 months) I have to wait if one of them get free or order an Hong Kong prepayed SIM card. But my question is, it's possible to change the code or bypass it? Thanks

I wasn't able to register either, but the social login via Facebook works just fine. Give it a shot login with your Google+ or Facebook account, it should let you in.

Okay, i don't know that's possible with an Social media account. I try this today's evening. Back to my core question: If I get the Code, if is possible to change it?
Thanks Ante

I think it's not possible to change it without unlocking your phone at least once, but after unlocking, you'll not need the code again, so there's no point in changing the code at all.
The bootloader will remain unlocked, and I haven't found a way to relock it again.
I tried these commands:
Code:
fastboot oem lock 16digit_code_here
AND
fastboot oem relock 16digit_code_here
Sadly non of them worked.

Okay, i copy that but I think it`s sounds bad. I only open the bootloader of an device to root it or to install a custom ROM. After I finished my work I close it to prevent hijacking or bypass my device encryption keys. Btw I have only use nVidia Shield Tabs and there are Dev friendly. At the point when you open the bootloader all data is wiped! Is this on all Huawei device? I think I looking for a new device. The new Lumia 950 sounds good, but Windows? I hope there are possible to open the bootloader and install Android with an custom Kernel ?

For bussiness use I only recommend Microsoft phones or iPhones. These are well protected all round, almost with no customization options and the system works so well by default you don't even need it at all.
For personal use, I recommend Android. The most customizable OS nowadays.
As I said, my bootloader is unlocked, and I was afraid to lose all my data as well, but everything was in place after the unlock.
The Huawei crew is pretty developer friendly, I think. They put out the kernel sources, made the bootloader unlockable via the site(yes, it's not fully functional, but hey )
I've had a S3 mini before this and we had to beg for Samsung to release some drivers in order to get CM11 working fully.

I don't trust Microsoft in this case. A whole OS for free as a upgrade? Come on, realy? There are much more behind the scene as you and i can see. Windows 10 talk a lot with unknowen Servers. Try it yourself: Install Win 10 as a VM, disable all settings in the privacy settings and capture all with Wireshark. You see a lot of encrypted connections to unknowen (by RIPE, not Microsoft) IP addresses. Apple earn his profit with selling hardware, Google with seling Ads based on user Data and Microsoft with seling Software. I like the hardware of the 950, but it be only usefull for me when i can install any linux based operating system.
But enough oftopic
I have give away my Huawei P8 lite and looking around for a new one, but out there is not "my perfect" device.
I remember, reclosing and changing bootloader code are (currently) not possible.
Thanks for the conversation daviddosa

Cannot Connect to network after unlock (clean up) FIXED

Hurrah! this has been fixed WOO!.
see here.
well done guys, you have made me a happy g2 owner again!!
Hi Everyone,
i figured we might need to clean up the
http://forum.xda-developers.com/showthread.php?t=805024
conversation.
as i see it, there are 2 issues
1. people receive an unlock code, the phone accepts it but then it cannot find any network
2. people receive an unlock code, have troubles entering the code but eventually get it in ok.
please do not post anything "setting" related - apn's, bands etc as this has been tried and shown not to work (yet)
it might be helpful if people who have issue number 1 could post some answers to some questions.
as i am not at all smart enough to work out what we need to know from these people, id appreciate it if those in the know could pm me what they think could be useful, and ill make a template for people to follow

Current Theories: (please PM me if i have anything wrong here or if i need to add details.)
-------------
Theory #1
Ghul99: the code is accepted, but the phone is still locked?
http://forum.xda-developers.com/show...&postcount=121
------------
interesting information
this seems to support theory #1
1. i unlocked phone - code entered successfully, and i was no longer prompted to enter an unlock code
2. i perm-rooted my phone - all went to plan
3. i put the vision rom on my phone (http://forum.xda-developers.com/showthread.php?t=834450) loaded ok
4. i put a sim in my phone and now i am prompted for an unlock code.
5. i tried to re-enter my code but it would not accept it (it is the same code from step 1)
Nice idea for taking the initiative to clean up the thread which was getting excessilely long!
I'm hoping we can see some progress in a few days as I'm really missing being able to get any cell reception on a MOBILE PHONE!?
Regards.
I will summerize my knowledge later but one thing upfront.
IntuativNipple posted today in IRC that he found the way to get real S-OFF which would also allow SIM-unlock without code.
So there is hope for a solution, but keep your patience.

Just to help guhl and catch up with some unnecessary posts.
Common solutions like Reboot, different sims to try, Hard reset, flash stock ROM or trigger the unlock window to reenter the code doesn't work
Summary of my knowledge so far
For case 1 which was the original problem my theory is the following.
Cause:
Because of problems with the write procedure to the emmc memory the MCCMCN to which the phone is locked did not get cleared but set to an arbitrary value in my case "C3AB".
The CID value is still the same as it used to be (and also in case of a successful unlock would stay the same) which is "T-MOB010". The CID is a 8 character string and the case where all characters are the same (i.e. "11111111") is called Super-CID.
It is of no relevance if you use or used the hardware or software keys, T-Mobile or third party sources. The only reason where it would be your fault is if you pulled the battery!
The unlock-code that we possess (regardless if official or from a different source) is not valid to unlock the phone from this value "C3AB". If one tries again (directly with the modem, using my modified libril.so or a different ROM) the lock counter will increase.
Potential ways to repair this state:
1. Give it back to T-Mobile if you can In my opinion this is a clear warranty case
2. Find someone who has the MegaSIM and the HTC-diag software.
This will definitely work but it is going to be hard to find someone because the SIM is rare and very new.
3. Wait until (or help achieving) the so called "real S-OFF" state of the phone (when also the radio has security disabled) is reached.
When this is achieved one can disable the SIM-lock without any code.
There are still some very good developers after this goal even if for different reasons.
Which information could help us:
1. The output of the following AT-Command sequence from successful and unsuccessful unlocks
Code:
ATE1
ATV1
[email protected]?
[email protected]?AA
[email protected]?40
[email protected]?80
I will try to write a HowTo later for Windows.
For linux see the following posting from the old thread (http://forum.xda-developers.com/showpost.php?p=8750299&postcount=121)
2. The next thing that would help is a logcat from the first unlock process itself.
Howto:
Start the first logcat using the USB-cable and adb before you boot the phone with the foreign SIM.
Code:
adb logcat -b radio > lc_unlock.txt
leave the logcat running and complete the unlock procedure till the phone reboots (the logcat will end automatically)
As soon as the first logcat exits start a new one using:
Code:
adb logcat -b radio > lc_after_unlock.txt
leave it running for 1 minute and then stop it using <Ctrl>-C
3. The next thing that really would help is that you do not post anything in this thread (use the old one instead) that has to do with:
- the APN
- trying another SIM (you would be very lucky if you had one that fits the arbitrary SIMlock)
- reboot, factory reset, use a stock or non stock firmware
- use the hw/sw-keyboard, wait for the right outside temperature or other esoteric procedures
Finally I would like to ask moodecow to edit his original posting and incorporate or link everything that he finds important or helpful in his posting so that it will stay an top.
That is some very exciting news, thank you for the update!
One quick question, when we achieve radio-s off it esssentially would mean everyone could unlock their phones for free?
Thanks.

I have 2 ideas, which can help:
1. For people before unlock - maybe performing S-off before unlock will help.\
2. For people after unlock: in bootloader there is "SIMLOCK" option. When you open it, it shows file not found etc. As I think, it can be used to simlock phone for operator, whose numbers are in some file. There is my solution - find what that files are in phone's source code or by any other method, then put them in right place, enter numbers of operator you want to use, open that "SIMLOCK" and lock phone to your network. I don't know if it will work, but it makes some sense.

Your first idea sounds reasonable and I would support it.
Your second idea is something that is worked on, but you do not only need the correct file (which is actually called DMCID.dat) but there also has to be some "magic number" (like on a gold card) on the micro-sd card.
an important piece of info to carryover from other thread:
1- No APNs are listed
2- if you try to define one, it doesnt save
No APNs being listed is related to the rom more or less, not the issue we're having.
APN is software issue, correct me if I'm wrong so either way it shouldn't pose as an issue to us.
im saying its a symptom that seems to go along with the problem in the title of this thread, so, worth noting.
ie: i think everyone who has the post-unlock no-connection problem, cannot save APNs. all others can.
if you are a counterexample please say so. that would help.

i have got HTC MEGA SIM and Almost all DIAG files but
T-mobile G2 case =After putting unlock code NO NETWORK cant be solved because when we give s58 clear command it shows SIMLOCK CORRUPTED
i can post the detailed info and pictures if you want it would be a pleasure if could help in any kind of DEVELOPMENT
BTW
if we don t put code in the same version,same country,purchased in the same lot of handsets and use MEGASIM directly without touching anything than it works perfect

So if megasim has failed due to corruption I think that the only way to solve our issue is to write directly to emmc partition holding locking information. And I don't now how easy and plausible this is...
I think if we get S-Off for Radio, we'll be able to write to that partition. I hope

I am a little bit worried about writing this information directly because the partition will be encrypted.
And also copying the complete partition from a working phone or one that is still unlocked will not be an option because the IMEI will also be there and we would not want to overwrite that.
So my hopes are more that there is some kind of a restore procedure from a secure area (I know that Nokia phones can do this, but HTC ?) or that we can lock the phone again with the SIMLOCK option in hboot.

[APP][ICS] EncPassChanger -- set different device encryption and lock screen password

Android 3+ has a nice feature -- device encryption. You can encrypt the contents of your device with a password, and after that this password must be entered during device boot, otherwise the data is permanently lost.
The bad thing is that this password is set to the screen lock PIN / password. So you either set a short password or PIN, that you can enter quickly each time you unlock your phone from sleep (but this provides weak encryption), or set a long password and have to type it 20-30 times during the day.
This stupid behavior may be fixed easily. Android provides command-line tool called 'vdc', an interface to Android Volume Manager. As written in "Notes on the implementation of encryption in Android 3.0" [1], it has a command 'cryptfs changepw', that allows changing encryption password. Of course this command must be executed as root.
vdc has some other commands related to encryption, one of them is 'cryptfs verifypw', that allows to validate the supplied password.
I'm currently writing an application that will assist user with changing encryption password. This is my first public application for Android. You can find a source code on GitHub [2]. It is very simple, but maybe android gurus here may find what to make better.
Comments and pull requests are welcome
Thanks!

Thank you for this. I wanted a more simple password for the unlock, but a longer more complicated password for the decryption. You should put it on the market and charge $.99USD (or equivalent in your currency) as it's quite useful. I'd buy it
Thank you!
Actually I have registered myself as Google Play Developer, now I'm waiting for approval. As soon as my registration is approved, I will update this thread
Although I'm going to make a free and donate versions, because I believe that will help to make Android better, and people who want to say "Thank you" will buy Donate version anyway

Nothing will change visually, hence no screenshot. What's important is that you may set strong password for decrypting the internal storage, but keep using simple password (or PIN) to unlock the screen.
P.S. I have verified that my app works on Jelly Bean too.
I have finally published an application on Google Play! Currently there is a free version, Donate version will come a bit later
The link is: https:// play.google.com/store/apps/details?id=com.kibab.android.EncPassChanger
Enjoy!
Thanks for that app, that is also what annoyed me
Thanks for this. I've been trying to work out why encryption wont work on any ROM on my HOX (dies with unable to get size of block device cryptfs), and you have given me a good lead to investigate with vdc. Information on encryption in android is sparse, and almost all threads here on XDA get no replies.
Thanks again.
I've been tempted to use device encryption recently, but there is a distinct lack of information about it, particularly on custom ROMs...
Might need to give it a go, just the lack of backup abilities might be an issue...

I use CM10 on the Galaxy Nexus (maguro). Encrypted. Actually, only /data is encrypted. /system stays unencrypted. And this App works as described.
For Backup use TWRP. It asks for your password to decrypt storage.
You can then backup, restore, flash, install whole ROMs, wipe and what not.

btw. The encrypted /data partition lets you have two boot animations, one that is shown before code has been entered (the one in /system/media) and one after the correct code entry (the one in /data/local).

Wish I had a second phone, then I could just research this
Quite awesome. Now, can I use a strong password for encryption and then pattern lock for normal day to day use? That would be my ideal situation. I heart pattern lock!
Just trying to clarify how this works... so you keep your normal 'short' pin unlock code for unlocking the screen, but set a long code for decryption, and this code will only be requested once per boot, during bootup? Is this correct?
Thanks
How it works
Yes Sir. You are correct.

Unfortunately it's not possible to use pattern lock while using device encryption, Android forbids it. Patching Android framework will help, but this is completely another story and possible suggestion for ROM makers such as Cyanogenmod.
Is the 16 character Android limitation present, when using this tool? I currently use a 16 character device encryption/unlock pass phrase. I'd like to strengthen the device pass phrase some more.
I don't know if this is even possible during the device boot sequence, but being able to use a Yubikey with an OTG cable would be awesome!

[GUIDE] SUCCESS!!! SIM-Unlock Sprint XT1056 (SIM-CRACK) Moto X GSM **NOW U.S. TOO!**

Greetings fellow XDAers,
It's finally happened: SIM-Unlock for the Sprint Moto X (XT1056)
(International-use Only. Anyone in the U.S. - Don't bother at the moment. Myself and some others are looking into the possibility of extending the SIM-CRACK to U.S. users, but RIGHT NOW, not possible. Sorry.) NOW EXTENDED TO DOMESTIC U.S. USERS AS WELL! - I have discovered the domestic-unlock solution!!!!
First, a little background:
Since its debut in August, 2013 many people have been trying to crack the SIM-LOCK on the XT1056. Many have tried and long since given up. I officially became involved in the project in May, 2014, and since then, had taken over the project. After much research, I determined that a Chinese hacker had found the solution and was offering a SIM-Unlock service on Taobao.com. This individual was extremely secretive about his methods - and told no one the solution. In order to use the service, you had to SEND your XT1056 to China to be unlocked (for fear of someone discovering his method). Then, a short time afterwards, the listing completely disappeared from Taobao, never to be seen again. Afterwards, sellers only offered PRE-SIM-CRACKED XT1056's on Taobao. Fortunately, I had already discovered (by reading his prior listing), that the SIM-Unlock required that you NEVER erase the modemst1 and/or modemst2 partitions (the equivalent of EFS/baseband cache on the Moto X).
At this point, I knew without a doubt that the key was in the modemst partitions. The breakthrough, however, didn't come until Mid-July, when another XDA Member: @yefonme posted to the thread that they had obtained a China-SIM-Cracked XT1056. This user confirmed the information I already knew by telling me that the seller advised that they must never erase the modemst partitions or the SIM-Unlock would be lost. This user generously offered to assist in helping find the solution, just for sheer curiosity - they wanted to know HOW the SIM-Unlock was achieved.
At this point, I thought we had everything we needed. Knowing that the key lies in the baseband cache, I requested various users to use a tool to backup their modemst1/modemst2 partitions, and send them to me for comparison with a HEX-Editor. Several users obliged, but unfortunately, we hit another roadblock -- the EFS partitions turned out to be ENCRYPTED TO HELL! That method was going nowhere. Then I realized that upon erasing the baseband cache (modemst1/modemst2 partitions), that all NV-ITEMS were reset to their factory defaults. BINGO! This means that the baseband cache partitions MUST store the encrypted contents of NVRAM!
This meant we had another option! Using standard CDMA tools, we could do a "DUMP" of the values stored in NVRAM. Another user, @ezeuba, suggested a simple tool, and provided instructions for the other's involved to DUMP the contents of their NVRAM, for comparison. Another big issue: Since many NVITEMS are inactive / restricted, even between 2 Sprint SIM-Locked devices, it made it completely impossible to use a utility to run a differential comparison between these NV-DUMPS. This meant that the NV-ITEMS had to be compared manually, by-hand.
I spent countless hours scouring through the data, comparing the THOUSANDS of NV-ITEMS from the China-Cracked XT1056 with the dumps provided by the Sprint SIM-Locked users. It was taking forever! I knew that the key to comparing the NVITEMS was finding values that were the SAME on all the Locked XT1056s, but DIFFERENT, only on the SIM-CRACKED XT1056. If a particular NVITEM differs between 2 or more LOCKED XT1056s, it is likely not the value we are looking for.
Then, finally, I came across an NVITEM that struck me as unique. It was the SAME on all the LOCKED XT1056's I analyzed, but different ONLY on the CRACKED XT1056. I was hesitantly optimistic, and posted about it here: http://forum.xda-developers.com/showpost.php?p=54334931&postcount=250
Well, my intuition was Spot-On, and this DID turn out to be the proverbial "smoking gun". Another user (ignoring my suggestions to WAIT and let another user who had offered to donate an XT1056 mainboard try it first) went ahead and wrote the new value as I had suggested. BAM!!! And the rest is HISTORY.
OK, so enough about the history, and on to the solution!!!!!
So the key lies in NVITEM # 8378
On the China-Cracked XT1056, the value was "01"
On all the SIM-LOCKED XT1056's, the value was "00"
That's all there is to it. You can use the CDMA Tool of your choice to write "01" to NVITEM 8378 to achieve SIM-Unlock!
You will also need to change the RUIM config to "RUIM-Only" in order to prevent the phone from reverting to CDMA-mode upon reboot. This is controlled by NVITEM 855 (see instructions in post # 2)
This method is KNOWN to unlock for all international GSM carriers, but DOES NOT unlock for Domestic U.S. carriers. Something else is in place, it appears, that BLOCKS the United States MCCs. NOW EXTENDED TO U.S. USERS AS WELL!!!
POST # 2 in this thread will be reserved for complete instructions for those of you who aren't familiar with how to write NV-ITEMS. These instructions are courtesy of @ezeuba.
POST # 3 will be reserved for detailed instructions on how to install the necessary DIAG Drivers, and how to manually FORCE driver installation, if necessary.
I believe in giving credit where it is due, so I want to personally thank:
* @hsngt and @jaaa1976 - who provided me with the NVDUMPS I used to find the SIM-Unlock method. @jaaa1976 was the FIRST person to be unlocked by my method
* @ezeuba for providing these users with step-by-step instructions on how to READ and SAVE said NVITEM dumps.
* @Vivjen for support and generous offer to donate a XT1056 mainboard (which turned out to be unnecessary)
* @crabbyone for encouraging me to take a 2nd look at NVITEM # 8322 (which turned out to be the Domestic Unlock solution)
* @Arnold Snarb for originally discovering the property of NVITEM # 8322 (which unlocked the Razr M for domestic use)
* All the others who submitted EFS and/or NVDUMPS (even though I didn't use them to find the solution)
* Everyone who believed in me and provided encouragement and moral support ( that includes YOU, @KJ )
* Everyone who makes good on their bounty pledges and everyone who DONATES (paypal: [email protected] )
* Everyone who is appreciative and gracious for the ENORMOUS amount of time I've spent making this SIM-Unlock possible for everyone
* The China-man who found the solution FIRST, even though he didn't share it with anyone and intended to only use it for Profit (I bet he is PISSED at me -- he was charging $80 U.S. for EACH unlock )
*** and ESPECIALLY @yefonme --- without YOU, NONE of this would be possible.
[Q]: How much should I donate to you for all the time (weeks) you spent working on this?
[A]: Please donate what you feel it is worth to you. The XT1056 can be found far cheaper than any other Moto X Variant, and now that we can SIM-UNLOCK it, it will become much more popular. If I have saved you money, or added value to the phone you already own, I would appreciate being compensated accordingly. I realize that some are not able to donate, and I understand. Do what you can / what you feel is fair. I spent countless hours on this, and would appreciate being somewhat-compensated for my efforts. This, of course, is not a requirement, since I have posted the solution and made it freely available to everyone. Keep in mind that the China Taobao-seller was charging $80 for EACH unlock...and HIS sim-crack didn't even unlock for Domestic U.S users!!!

DO NOT email me asking for help with this. I won't answer you. *Post in the Thread* - this is the only way you will get support. I'm sure that you understand...
Additional info:
This works for all Republic Wireless XT1049's also, but ONLY if you can unlock the bootloader (only possible through the "China Middleman" - use search). You MUST flash the Sprint XT1056 ROM to your RW XT1049 device for this to work for you.
DISCLAIMER:
If you use my SIM-CRACK, I'm not responsible for ANYTHING that goes wrong. USE CAUTION! If you hit the wrong button, or write the wrong NVITEM, you could end up in BIG TROUBLE (possible BRICK). You have been warned.
And lastly, YOU MAY ---NOT--- COPY ANY PART OF MY SIM-UNLOCK METHODS. YOU MAY NOT SHARE/RE-DISTRIBUTE MY FILES, OR POST THEM TO OTHER SITES. THE ONLY ACCEPTABLE THING IS TO ---LINK--- THIS THREAD TO OTHER SITES. IT IS UNACCEPTABLE TO STEAL MY (OR ANYONE ELSE'S) WORK!!!!! I will be extremely offended if I find that someone stole my work and posted it elsewhere. ONLY Link this thread. Don't copy any or all of its contents elsewhere. PERIOD.
^This is NOT an unreasonable request....
FULL INSTRUCTIONS ​
!!!!! A WORD OF WARNING:
Once you complete this method, it is possible that you will NEVER be able to use your phone on Sprint / CDMA again! I -stupidly- flashed my Republic Wireless XT1049 (I should have known better -- I am using their service, and had no intentions of switching to GSM) in attempt to get better results / instructions for you guys. Now my phone is STUCK in GSM mode, the roaming indicator will not go away, I can't make calls on CELL, and no matter what I've tried, I cannot revert back. Not flashing my EFS backup, nor flashing back to stock, nor erasing the modemst partitions has been able to get me back on CDMA. PRL is STUCK on "1", and no matter how many times I write a new PRL, it won't stick. I'll be lucky if I can get my phone back in working order.....
^EDIT to above: This turned out to be EASILY fixed by flashing the entire SPRINT SBF to my Republic Wireless device, then, subsequently flashing back the Republic Wireless ROM (I WANT to STAY on Republic Wireless). DO NOT ATTEMPT THIS SIM-Unlock on the Republic Wireless ROM. Something about the RW ROM prevents you from going back to CDMA once on GSM. Flash the SPRINT ROM, FIRST, if you want to GSM-Unlock your Republic Wireless XT1049. The SPRINT ROM does not seem to have this issue, so you are probably OK, but take caution, nonetheless. I'm finally back on Republic Wireless (CDMA) after hours of frustration and fear that I was permanently stuck on GSM.
I don't recommend this if you plan to ever go back to CDMA / Sprint Probably fine - But once again, use caution.
Still want to continue? ------> Don't blame me if you end up STUCK on GSM
If you want my support, you must be on the Stock XT1056 Sprint ROM. I will not support any other ROMS from any other variants, or any custom roms. If you change roms, good luck, but no support will be provided. Additionally, support will ONLY be provided by posting to this thread. Do not email me or PM me with questions. I'm sure you understand...
AND Don't forget: This DOES NOT unlock for Domestic use, in the United States. Blame Motorola/Sprint. Something else is in place, it seems, that BLOCKS the U.S. MCCs. If you live in the U.S., DON'T BOTHER, unless you plan to sell your device to someone overseas. Myself and others are looking into the possibility of extending the SIM-Unlock to those in the U.S., but hasn't happened YET. I've also discovered the DOMESTIC UNLOCK solution now, as well!!!
FIRST, you must be in DIAGNOSTIC MODE:
You MUST have "USB Debugging" DISABLED, or the DIAG Port will NOT activate!!!
ezeuba said:
There are 2 ways to get to DIAG mode on this device. If ##3424# doesn't work, you can try the default for most Motorola devices: Power off phone. Hold down BOTH Volume Buttons and press the Power Button (It's called the 3-finger salute). When the phone boots, it will display a diagnostic screen called Fastboot Mode with options to scroll to and select. Use the Volume Down Button to scroll and the Volume Up Button to select. Scroll to the bottom of that list and when BP TOOLS is highlighted, press the Volume Up Button. The phone will restart and if you have Motorola device drivers on your computer, it will install the correct port (something like BP DIAG port Motorola QC Diag Port - look for it in your computer's Device Manager to get the port number).[/B]

Click to collapse
****If you are having driver issues, and you have an entry for "Motorola QC Diag Interface" (not "Port") under "Other Devices" (and not "Ports (COM & LPT)"), SEE POST # 3 for detailed instructions (WITH PICTURES) on how to FORCE the driver installation.
Next, download and install the attached "SPCUtility.apk" app on your phone. Run it -- it will give you YOUR SPC Code. Write it down / take note of it.
IF ANYONE CAN TELL ME WHO DEVELOPED THIS APP, I WILL GIVE THEM THE APPROPRIATE CREDIT. I have tried (without success) to find out who the author is.
Then, flash the attached nv-unlock.txt, nv-unlock2.txt, unlock-domestic.txt AND nv-ruim-only.txt files as per these instructions:
1. Open the attached "NV-Items Reader-Writer"
2. Enter YOUR COM PORT # as shown in DEVICE Manager
3. Enter YOUR SPC Code into the box, as shown.
4. Check the box immediately next to where you entered the SPC Code.
5. Click "Connect"!
Now, follow these instructions:
1. Click "READ" --AT THE TOP--
2. Make sure it says: "SPC is Correct. Phone Unlocked."
3. Click the "Write" button, and find the "nv-unlock.txt" file - make sure it confirms success
4. Click the "Write" button, and find the "nv-unlock2.txt" file - make sure this confirms success
5. Click the "Write" button, and find the "unlock-domestic.txt" file - make sure this also confirms success
6. Click the "Write" button, and find the "nv-ruim-only.txt" fine - and make sure it confirms success as well
7. Last, click MODE, then RESET
And lastly, once the phone reboots, go to Settings, More, Mobile Networks and select GSM/UMTS.
DONE! You are SIM-Unlocked!
KNOWN ISSUES: On domestic carriers, users are reporting that although it DOES work, the signal bars may show no service. (I am looking into this.) Additionally, if data isn't working, YOU NEED TO INPUT THE PROPER APN FOR YOUR CARRIER (as with all GSM phones).
^^^***THIS MAY BE SOLVED*** Apparently, it involves simply using fastboot to set your carrier! (THANKS, @ejlmd , and @leonardoafa !!!) You can see this post for more details: http://forum.xda-developers.com/showpost.php?p=54468353&postcount=126 (And hit the "THANKS" to @ejlmd, and @leonardoafa in the linked post). This **should** fix your signal bar issues, AND roaming indicator, and allow SMS without issue.
ALSO, you will NOT get LTE data...on any carrier except Sprint because the radio inside doesn't support any LTE bands except 25 (used by Sprint). You also won't get HSPA/HSPA+ (3G/4G) data for any carrier using frequencies not supported by the Sprint Moto X. For instance: If you are using T-Mobile, unless you are in an area that has been re-farmed to 1900mhz HSPA/HSPA+, you will only get EDGE data. This is because T-Mobile extensively uses HSPA/HSPA+ on the 1700mhz AWS band which is not supported by the Sprint Moto X. See the link below for a complete list of frequencies supported by the XT1056.
http://en.wikipedia.org/wiki/Moto_X
Keep in mind that once you write the "nv-ruim-only.txt" file, you will no longer be able to use CDMA without flashing the "revert" file listed below (puts you back on the default RUIM-CONFIG). The "revert" file is ONLY to be used if you want (for some reason) to switch back to CDMA. You do not need it if you intend to only use GSM. Also, the purpose of "nv-unlock2" is to unlock the MIP settings, and prevent the phone from reverting BACK to NV-Only upon reboot.
Additionally, keep in mind that if you ever "SBF" back to stock, using RSD Lite (or fastboot method), it will un-do the SIM-CRACK, and you will need to repeat these steps.
You ***SHOULD*** be able to accept Updates (OTAs) without losing the SIM-CRACK.
*****If you click any of the attached TXT files, and it OPENS in your browser, instead of downloading, RIGHT-CLICK on it, and click "Save Link As" -- it should download without issue.
[Q]: How much should I donate to you for all the time (weeks) you spent working on this?

Driver Issues?​
This post is for you.
In order to use the DIAG interface, you must first install the Motorola Drivers from here: https://motorola-global-portal.custhelp.com/app/answers/detail/a_id/88481
REMEMBER: As stated in POST # 2, you MUST have "USB Debugging" DISABLED, or the DIAG port will NOT activate.
If you installed these drivers, and you still can't get it to work, and you have an entry under "Other Devices" (In Device Manager) called "Motorola QC Diag Interface" (SEE PIC1, attached below) follow the instructions in the attached pictures STEP-BY-STEP, IN ORDER, to FORCE driver installation.
We are ONLY concerned with the QC Diag Interface - don't worry about the rest of the entries under "Unknown Devices" -- these are not important.
Once you have successfully FORCED the driver installation, you should have an entry under Ports (COM & LPT), called "Motorola QC Diag Port (COMX)" (SEE PIC8, attached below). NOTE the value of "X" - this is the COM port you will use for our purposes. When you successfully have this entry, you can continue with the "FULL INSTRUCTIONS" in POST # 2.

Excellent! Please get me the instructions & necessary tools to use ASAP so I can post it in Post # 2 for the users who need step-by-step instructions. Thanks for all your help as well - I have given you credit accordingly.
Excellent work,buddy!!!
Thanks to your efforts, I can imagine how difficult it is.
And I was very pleased to be able to help.:victory:
Done!!!
Just flash this attached file. Connect as usual to the NV-ITEMS Reader/Writer. Click Write and select the attached file which you must have downloaded. After writing, go to Mode and click reset. Phone will restart. Go to Settings, More, Mobile Networks and select GSM/UMTS. Phone unlocked. Special thanks again to @samwathegreat without whom this will not be possible.
I'm on GSM right now...
NB If you've been using this phone on CDMA, you need to change RUIM Config to RUIM Only, else whenever you restart it will revert back to CDMA mode.

POST # 2 Updated. Thanks!!!!!
hey man, amazing job on this! so many people will happy to see this!
You're the man!!!
Thanks again everyone.
I REALLY need someone in the United States to test this and advise whether or not it unlocks for Domestic (U.S.) GSM Carriers.
We know that the "official" Sprint OTA-Sim-Unlock (only offered if you are a current sprint customer, have had an account for a specified amount of time, and meet other criteria) does NOT unlock for domestic use (international only).
I'm anxious to find out if my SIM-CRACK unlocks for those of us in the U.S. -- I need to know ASAP so I can update my OP accordingly.
@samwathegreat
If it is possible that you could make a video or how to flash this to your phone I think it would be beneficial to some. Even if your phone is already unlocked if you can flash this way then I feel that it's going to stop the millions of questions that are going to come from the thread. Just my two cents, thanks again :good: :victory: :highfive:

Good suggestion. Full, detailed, instructions are listed in POST # 2 already, but this could help some, and I could put it in POST # 3. I'll see if I can get another user to make a video.
Remember: I don't own an XT1056: I did all of this for YOU GUYS, and all without even owning a Sprint XT1056
You are welcome to create a video yourself! I think the instructions are concise enough that you should be able to manage making a video. If you do, I'll post it in #3 and give you appropriate credit for it.

I don't have the appropriate equipment or environment (living in a 'college dorm' (kinda like that) with 24 people, it's never quiet) otherwise I would make one ASAP.
You don't even have one?! OH MY GOD. Your amazing doing all of this without the device...
Also a few things, I can't download the .txt file... I can only view what it says... So how do I download that, and then from that where do I put it to flash, just in the text box?

No idea? Use the NV-ITEM reader/writer attached in POST # 2 to read NVITEM 8378
Under Range (Dec), type 8378 into both fields (type nothing into the HEX boxes) and click READ. If NV8378 is "00", there is a good chance it will. Try and let me know!!!! If it already reads "01", it won't work.
...can't you get a SIM-Unlock code from a regular GSM Sim-Unlock-Code seller for the XT1052?
actually I don't need sim unlock....but, some of french moto X owner bought their phone on US (XT1053 sorry, not XT1052).
But my question is the same: does it work on other moto X model ?
I'm gonna try you method to see what happen.

ALL XT1053s should already be sim-unlocked. In fact, all variants except the XT1056 and XT1049 (that aren't -already- unlocked) can be SIM-Unlocked using the normal methods...(online code-sellers, etc.)
My method definitely works on all XT1056s.
It *SHOULD* work on all XT1049s (Republic Wireless), but ONLY if you unlock the BL and flash the XT1056 ROM to it.

Thanks for the update. Can you provide more detailed instructions on how to change to RUIM only? I know how to do this....with DFS anyways....but many won't. Which tool do you suggest?
Actually, I believe that RUIM config is also stored in a NV item!
I *believe* that it is NVITEM 855 --- can you check for me? If I'm right, "00" = RUIM only, and "01" = default setting. Can you confirm?!?!
We could just update the txt file with this one additional NV-Value, and the users would only have to flash the ONE file, and it will crack AND set the RUIM config to RUIM only.
What do you think?

Samsung tablet 500t, reset, and loss of password

Hi everyone,
A friend of mine got a second-hand tablet Samsung 500t from one of her relatives.
She set her password, but she forgot it after a while. She asked me to help her to sort the problem out but I don't know windows RT and I don't know exactly what to do. In addition, we don't have any cd or user's manual. I tried to reset and I launched the procedure which always ended up with this message:
"Insert your windows installation or recovery media to continue".
I don't know what to do now, and, unfortunately, she hasn't got any back up.
Can anyone help me? Thank you.
Is she using a local account or a Microsoft account? If the latter, you can just reset your password the same way you would if you forgot, say, your Hotmail password. Go to https://login.live.com and follow the "forgot password" steps.
If it's a local account, that's more awkward. There are various steps (short of a full wipe) that you can do, but if you don't know the Admin password then most of the non-wipe options require things like Linux liveCD (or live flashdrive) images and forcibly resetting the password.

She is using a local account. We asked her relative, the former owner, about a Microsoft account, but he didn't know and remember anything about that.
Can you explain me more about using a Distro Linux to reset the password on the tablet?
I used a linux live many times, and I can manage it for easy tasks, but I have never used it to reset or to recover a password on a Window OS.
Thank you, Bob.
If you boot a Linux live image - probably off a flashdrive, unless you have a handy USB optical drive - it can mount the internal NTFS file system and find Security Account Manager (SAM). There are tools that will modify a SAM file to overwrite the password for a user. It's also possible for some tools to brute-force the password, though this can take a long time, or to look it up in a "rainbow table" of pre-computed password hashes (won't work for really complex passwords, though). Forcibly resetting the password will cause you to lose any data encrypted with it, which may include things like passwords the OS was storing for you.
Some stuff that can be used to try and recover passwords (or reset them): http://smallvoid.com/article/winnt-password-recovery.html
There's a bunch of others out there too. Here's another link: http://www.mydigitallife.info/reset...trator-or-user-password-with-chntpw-in-linux/

Can I simply delete the SAM file? I don't think she cares to lose any data so much.
Ok. I was wondering how I can run the usb drive on a windows rt tablet. Is there a "boot device option" like on an ordinary pc/notebook?
Thanks again?:
PS: By the way, where can I find an image of Window 8 rt if I want to totally reset the tablet and install a clear OS?
Aw crap, I can't believe this but I forgot you were talking about an RT device. Forget everything I just said; Secure Boot won't allow it to run a Linux image even if you had an ARM-based one.
Deleting the entire SAM will render the device unbootable. It's not just user account logon details stored there; every account (including the various system ones) are there. On the other hand, if you can extract the SAM somehow, another computer will be able to edit it just fine even though it comes from RT; it's a registry hive and is architecture-independent.
Total reset is probably the easiest option, if she doesn't mind the risk of losing data. It requires a device-specific image though; there should be one (recovery partition) on the tablet, but if that was removed you'll need to find one for download or get Samsung to handle it for you. The Surface RT / 2 images are available here on XDA but I don't know about any of the Samsung tablets.
Go look on the support website (or call support) for instructions on performing a factory reset of the tablet under normal circumstances. That will work if the recovery partition wasn't removed.

Ok, I understood.
Can I somehow install a Window 8.1 pro x86 on this device? It has got an Intel Atom processor, after all.
I need drivers, though.
Thanks again.
Now you say it's a x86 device while earlier it was ARM (Windows RT). Make up your mind, it can't be both!

...hmm actually I'm not sure. The tablet is not mine. I thought it had a Windows Rt OS. But since you say that it can't be an x86 device with an RT OS at same time...I need to find out what it really is. Thanks.
OK
I've finally found out what the OS is?
It's window 8 32bit.
The complete name of the tablet is:

More, I have it at my home now.
Can we continue the topic?

Then the methods GoodDayToDie mentioned in post #4 should work
ok
I fixed it by using Lazesoft recovery.

Loss Password? All is not loss, even with the fact you can not boot from a USB stick drive with a password reset tool on it. The answer is actually quite simple with local access to the device Windows 8 is installed on. As long as you can get into recovery by using the "hold volume up" and pushing "Power" button method. You then simply picked Advance Recovery Options till you see Command Prompt in the menu and here's the link that'll take you the rest of the way below. What this does is replace Access Tools (for blind, etc) in Login Screen (lower left corner) with a Command Prompt window. Since it's in with the Root C drive, it makes it quite simple to merely change the password right there and be able to use it to log in immediately.
Thought your computer was safe from hackers locally? Think again (can only be run locally though, not remotely), but if you didn't have this option none of the free or pay4 password reset tools would work either. This is what they are actually doing and then they remove the Command Prompt window when done. Just like you will after using this very simple method. Or you need to use Windows Password Key to reset Samsung password.

[Expired]Get WP 10 for every Windows Phone and everyone with 3 easy steps

-------------------------------------
This method doesn't work any more on the latest version of Windows Insider app, Microsoft has fixed the vulnerability.
-------------------------------------
I post this method several hours after the release of Windows 10 for phone.
It original wrote in Chinese, I decided not to post on XDA, because I'm lazy to translate, I posted it on Chinese WP forum WPXAP.com and wish someone will translate it.
Today I noticed that there only a complicated method was posted here, so finally I decided to post an English version of my method.
What you need to do is: Download a file, Set a proxy and Get update.
No PC needed, you can done it within 2 minutes.
Details step for noobs (Read notice below before you really follow the steps) :
0.Open http://upwp10.chinacloudapp.cn:7777 in IE on your phone (My server is in China, maybe slow)
1.Tap 'Open', then 'Install'
2.Open Wifi Settings
3.Tap Wifi network you connected
4.Turn on Proxy
5.Server: upwp10.chinacloudapp.cn
6.Port: 7777, and save
7.Open Windows Insider
8.Tap 'Get preview builds'
9.Two or three options will show up (1st time you use this method, you'll get only 2 options. Otherwise, you will see 'Restore' additional)
10.Long-press Back key, back to Wifi settings, turn off proxy, then back to Windows Insider
11.Tap 'Insider Fast', then tap 'Accept' (Ignore any Chinese text you see)
12.You will get update
Notice:
Use at your own risk. Strongly recommend you test it on your second phone, do not update your primary phone.
Your token information(not password) of Live ID may be sent to my server automatically by phone, if you don't trust me, don't trust this method.
You can't use my proxy server to access internet, so don't forget to turn it off.
Make Backup, you may need Rest or Reflash your phone.
Huawei and Duo-SIM phone are not supported according to Microsoft.
Your phone model infomation will be changed to Lumia 636 after using this method. If you want to revert to your phone's original model, tap the 3rd option in step 9 and apply.
Check your 'Sys free space' in 'about' in Windows Insider. You need at least 250MB to install WP 10, or you will get 0x80188308 error (Sys free space show in Bytes, you need devide 1024 twice to get MB value. e.g. 556,646,400=530.86MB).
The only way to enlarge 'Sys free space' is Reset Phone or Reflash ROM. Reset only enlarge a little space usually, so I recommend Reflash ROM using Windows Phone Recovery Tool by Microsoft.
You will need about 500-700MB Phone free space (not Sys free space) to download the update, or you'll get 8018830f error.
DO NOT reset your phone if failed to update WP10, Windows Insider will broken(crash), it's a bug of Microsoft.
If you didn't join Preview for Developers program before (Means your OS version is below 341, usually 200), you will get WP8.1/341 update first, reboot twice follow the tips of Windows Insider, finally you'll receive WP10 update.
A lot of users repotered that OS version higher than 341(like 359 on new Lumias), you'll not receive WP10 update.
Damn. I thought I needed more system space, so I did a hard reset. Damn it I'm screwed. Anyway to fix it?

If you own a Nokia pone, you can try following this tutorial and reflash with Nokia Care Suite your original, or some generic firmware, if you need help getting your product code, you can get it looking under your battery there should be an RM-XXX code followed by another code of some 17 numbers (not your IMEI) and then you put on the "Data PAckage Manager" your Product Type (RM-SOMETHING) and your Product Code that are the first 7 numbers from that long code... Hope this helps to you
Help me :c

Reker,
I couldn't understand this part. I need to hard reset my phone via Windows Phone Recovery Tool, but I can't do it if i fail to update my phone to WP10? And my Windows Insider app will break?
Can you please clarify that part to me and send me some screenshots of your device too?
Thanks

Factory resetting your phone will break the windows insider app, as per Reker's instructions. Reflashing your ROM is the only way to increase your system space if you're below the minimum required system space. It's a pain in the ass, another step to make you think twice about it.
So, has anyone tried this on a Lumia 521?
If not I will try it.
EDIT: Not enough System free space, about 124MB.
EDIT #2: Trying a clean flash of the ROM, as suggested.

So far so good, will post when install of Windows 10 is completed.

Nice tip, but when I want go back to my original settings:
Your phone model infomation will be changed to Lumia 636 after using this method. If you want to change it back, tap the 3rd option in step 9.

Changed my settings to 1040_1021 (for Lumia 730). I have Lumia 930 RM-1045. How to change it to original ?

Changing back means having the registry information back as your phone originally had? the manufacturermodelname: RM-1045_1006 for eg. instead of the information this patch is applying.
Work with Lumia 920? If i do this how to back to 8.1?

Work. And you can go back with Lumia Software Recovery Tool or Nokia Care Suite.
And the Software Recovery tool back to 920 firmware not 636?
Windows Phone Recovery Tool will 100% return your phone to the correct OS
I had mine set to the L635, used the Windows Phone Recovery Tool and it recovered my phone back to the L625 100% working as it should
Some information is incorrect in the OP of this thread. You don't need at least 700 Mb, you only need at least 510-520mb for the wp10 update to install.
Also, as a reminder to users. When you set a phonemanufacturername, the mobile operator that the phone model appears on MUST ALSO match for you to receive the updates
Thanks loads. This worked perfectly on my Lumia 1320. Far simpler than that other method posted. This is in desperate need of a sticky.
I have followed the steps to the dot.. but my 930 keeps rebooting and receiving nothing.. I turn off the proxy, tap Insider (Fast).. I get "configuring your device..." screen, ajfnajksnfk in chinese, tap accept.. your device will reboot and so far it has rebooted 5 times, but no update yet.. what am I doing wrong?

Same to me
Now lets suppose, I successfully get W10 without resetting my phone. Will my 920 be known as 635 forever or will it get the right 920 software once W10 preview will be available for every phone??
Will I be forced to do the rollback to WP8.1???
Thanks!
