I was wondering if it is possible to flash G781U firmware on G781B since they have the same specs.
would love to hear what you think (or know).
Thanks
I'd keep the B model as it is as it can have it's bootloader unlocked. if you're taking that phone to the states someone would gladly buy it off you as is.
if you wanted updates after moving they could easily be manually downloaded and flashed. if you concerned about frequency bands then maybe there are ways to tackle that.

Thanks for the reply, I know its better to keep it that way but if I wanted to change it anyway, will it be possible or would I just brick the phone?

not sure to be honest, I suspect that the existing bootloader would generate a fail error before or just after you started but I can't say for sure.
if it did fail after starting to flash you'd need B firmware on hand to make it useable again.
Trying the same but switching from 781W to 781B. Had no success so far. Odin is failing to flash. At least so far I did not brick the device. Any advice is welcome

did you try to unlock the bootloader first?

tried, but so far without success. I'm missing the "OEM unlocking" option that is stated in the manual. Trying now to update to latest firmware. Maybe this will enable the unlocking option.
hm... I just learned that there may be no OEM unlocking option on my snapdragon device. There really is a lot to consider... Somehow OEM unlocking does not work on snapdragon devices from north america. In latin america although this might work. I don't really get what the point of all this is. [some sauce]
edit: maybe it is possible to unlock it through fastboot, but so far i only get a command not found error when using ´´´fastboot oem unlock´´´

Yeah, from what I understand devices with U at the end of their model number are missing the OEM unlocking option. I think its stupid to only block the option to some of the world, I mean either block it completely or dont block it at all.
Maybe it is possible to change your model to W and then unlock it, I im not wrong you are supposed to be able to flash W firmware on your U device without unlocking the bootloader.
Just make sure you download firmware with the same binary number in the baseband (the fifth number from the right)

Unlike the original poster I am trying to go from SM-G781W to SM-G781B (or anything else that has german language).
To my understanding Samsung does this as the carriers in North America are requiring it, but not sure why.

I looked on Cyanogenmod's website below:
https://download.cyanogenmod.org/?device=shamu
and it just has 1 ROM for Nexus 6. I have Nexus 6 for Sprint. Is there only 1 version of the ROM that works for all carriers ?
My old Galaxy S4 has many different builds for Sprint, ATT, Verizon, etc.... wasn't sure if Nexus has the same set up.
Yes, applies to all N6 variants.
thats because every sgs4 has a different setup for different carriers. we only have one nexus 6, and its the same for every carrier.

I didn't have a locked bootloader with Sprint Galaxy S4. If I were to restore the Nexus 6 back to stock to do an OTA update to update everything, then re-root and put a new custom ROM does the bootloader need to be re-locked, or can the factory .img be suffice to do an OTA ?
I'm still trying to learn how to do this as it is much different than the Samsung GS4. I saw there is a Nexus Toolkit by wug fresh. Is there any benefit to doing these processes by adb vs just using this progra which seems easier ?

you dont use adb for it, you use fastboot. and doung it right vs a toolkit.. toolkits dont teach you anything, and can mess things up.

bootloader can be locked or unlocked, it doesnt matter. but i recommend that you keep it unlocked forever, as it can save your phone in certain situations. and having it locked can be the end of your device, in the same situations.

Ok. That's what I was planning on doing once it becomes unlocked. I was going to have it set like my previous GS4 and just toggle custom ROMs from there. When you mention having it locked, are you referring to when people have re-locked the bootloader then had an error flashing the stock custom ROM thus bricking the phone ? That's what worries me. Looks like the security is more stringent on the new Nexus vs. older versions.

i was actually refering to it because of the unlock setting that has to be ticked to unlock. some stock users got caught in a bootloop, then cant boot up to tick the setting, to fix their bootloop. since it cant get unlocked, their phones are a "brick".

Is this what happened to this person below ?:

Since the stock rom did not have developer options "checked" then the bootloader can't be unlocked ? How can you tick the OEM unlock if it is in a bootloop ?

Ok that makes sense. What is the purpose of having the bootloader come locked in a stock phone then ? What does it actually do ? Prevents root ? I probably took it for granted mine was always unlocked before so all I had to do was worry about flashing the proper carrier ROM

Security.
Security in that if stolen your phone cannot be made to work for someone else...
Someone can (and likely will [emoji14]) correct me if I am wrong... But does little to secure your data...ESPECIALLY if you stay encrypted.

It does nothing to secure data from remote access, but it will protect data (if set with a password) from physical access, providing they do not know the password. The bootloader being unlocked, with no password on encryption would allow them to flash a custom recovery and pull the data off. This will be decrypted on the fly. So it works in conjunction with Encryption. To secure data from physical access, you need both.
IF your bootloader is unlocked and you have no password, you may aswell not be encrypted
Okay so i have read a few thread posts but all this seems a bit too confusing. Here is the situation. I bought a used S6-G920T which is unlocked as of now, i don't know what method was used to unlock it since i bought it pre unlocked. My sim(Non T-Mobile) is working fine. I am on 5.1.1- BASEBAND: G920TUVU3DOJ7, what i want to do is update to marshmallow, the official OTA isn't really available as it says the system was tampered with. I want to know if it is safe to update to 6.0.1 via odin without losing my unlock. Thanks in advance to anyone who bothered to read through.
BTW as of now i don't have root access.
What do you mean when you say you're unlocked?
You can use Odin to update the phone to newer baseband and bootloader; you can then use Odin to flash TWRP, and install the ROM of your choice.

I'm pretty sure the phone unlock has something to do with the IMEI of the phone being tied to the carrier. If it is unlocked, you should be able to use it on any carrier. It sounds like the process takes place in a special partition that is at the lower levels, like the bootloader, and does not change regardless of what software is used on the phone. I'd say just go for it and update, I can't see any reason why it wouldn't work, even after an Odin flash.
Just wanted to confirm from somebody that unlocking the bootloader after relocking it isn't a problem.
ie; Unlock > Relock (to recieve ota or go back to stock) > Unlock again at future time.
I know in the past with other phones, this could cause problems.

I haven't seen anyone actually re lock it. It fails unless you run the command a few times in the right order. You don't need to lock it again for anything. You can use RSDlite to flash the new firmware (whole package) using the servicefile instead of the flashfile and it won't wipe any data. Just like applying an update.

It's in the firmware package. When you extract it, RSDlite will will use one or the other. Flashfile wipes data, servicefile does not.

Thanks. Just got around to downloading it and I see what you mean. RSD just does a fastboot flash for you and if you use the servicefile, it omits the "fastboot erase userdata" command. I remember when RSD would boot to Motorola's own download mode similar to Samsung's and Odin. I see it just uses fastboot now.

None that I can confirm. They locked them with new methods.
Unlocking by official means will always work. Meaning meet the carriers criteria, like activating the device on their network for 60 days (each carrier is different) then requesting unlock.
I've heard of unlock services, but never needed to try so cannot confirm.

although you're asking in the totally wrong place I'll tell you this:
It's probably not possible. New phones are locked down tight. If it is possible, expensive equipment is probably needed. Your best bet is to see if there's an unlocking service on eBay. If there's not, it's a pretty good indication that it's not possible at the moment. If there is, it'll be pretty cheap and worth paying someone else to do. Now hit thanks for highjacking my thread.
hi all,
Just having a thought (might not work but thought i'd ask)
Some OTA's / Firmwares which you can install from the bootloader have the ability to re-lock the device, would the same be possible for the other way around?
I mean i'm on a locked bootloader now cos of the crap i installed which updated me to 9.1, it relocked the bootloader, I can turn on OEM unlocking (FRP) but obviously it remains unlocked.
Would there be a way to repackage a firmware package so that it does the opposite to re-locking?
I think everyone has pretty much given up on Huawei devices, I was just trying to disable zRAM and i can't.
Any thoughts ? Is this a possible avenue? or is this simply not going to work?
I'd guess the latter but thought i'd ask.
Which firmware version relocked your bootloader? I can perhaps take a look at it in my free time.

Nope! DLOAD re-lock bootloader to factory condition, but there's no way to unlock the bootloader with it.
I don't think Huawei will give you the unlock code a second time, but maybe you will be lucky, who knows.
Maybe you can retrieve it from an email from them!?
Edit: You can download your HuaweiID data from Settings - > HuaweiID - > Privacy Center but i doubt you will get the bootloader code from there

Hi there,
I'm currently trying to re-lock the bootloader of my Xperia XZ1C. I already flashed to stock firmware.
Like some people have issues to unlock the bootloader (https://forum.xda-developers.com/t/sony-xperia-xz1-sov36-bootloader-unlock-issuae-issue.4182675/), FlashTool fails the same way for me to re-lock.
As soon as I start BLU, the tool fails with ERROR-Cannot invoke "String.split(String)" because the return value of "java.util.Properties.getProperty(String)" is null.
fastboot oem lock does not work either (unknown command).
Is there any known way how to re-lock the bootloader?
Thanks in advance!
Reinstall fastboot ADB, install a newer version
[TOOL][Windows][Script]Get & Install Latest Official ADB & Fastboot Drivers
Most ADB-FASTBOOT installers are provided in UPXed .EXE-file format hence it's not transparent what they are internally doing unless you decompile it. So I decided to write the whole thing as a Windows CMD script thus everyone should can read...

You cannot re-lock the XZ1c bootloader.
All of the guides for unlocking emphasize that pretty clearly.

No, they won't. The phone has been out for many years, and a large number of very smart people have tried.
And if they used an eFuze or something then it's definitely irreversible.
Don't get the person's hopes up with "maybe one day".
For all intents and purposes, the answer is no.

You're kidding, right? If you started _exploring_ whether there was a way, then until you solve the problem, it's still not possible until you actually do it.
Your attempts don't change that, though we could potentially say "you can't right now, but some folks are working on trying."
if I tell you I'm trying to build a time machine, does that mean time travel is possible? Of course not. That only changes when it's successful.
