Any difference between g8441 and docomo japanese version? - Sony Xperia XZ1 Compact Questions & Answers

Heya, after switching out yesterday from my first xz1 compact after 3 years to my 2nd one, i'd like to buy spare one, and i'd like to buy a cheap docomo one but will it work in france for the 4g/3g bands please?
is there anything i should be aware of please compared to the g8441 please?

There is a difference in coverage of frequency bands between them. According to Frequency Check docomo does work with existing carriers in France, albeit g8441 has more extensive coverage and might work better in certain cases/areas.
Almost certainly, in case of docomo you'll have to pay to get your bootloader unlocked if you want root or custom ROM on board (23GBP is the price last I checked). There are also small possibilities of either docomo with a freely unlockable bootloader, g8441 with a bootloader which has to be paid to unlock, or docomo advertised as g8441.
No matter the version, I would buy from a place that accepts (free) returns just to be on the safe side. Some ebay sellers offer them.

Thanks a lot dude!! it's sad that there are some missing bands , it's hard to find a G8441 with decent price after having mine for 3 years, i check ebay quite often

This is very interesting info. Thank you.
I am wondering if it could be possible to unlock the LTE band 20 on "docomo advertised as G8441" board?
I just happen to be the unlucky one to get Japanese version of xz1c motherboard unfortunately.

I'm probably late, but if you want bl unlocking the docomo version i think it's impossible even if with the mentioned software tool 23gbp, they have some dark magick locking on this version, even if you unlock it, you will run into problems flashing custom firmware i think this is all true I've owned a docomo xz1c as my main phone for more than one year, tried everything there is

It will be only with stock rom using temp root from J4nn, but since unlock 4g band b20 is impossible, I will need to learn to repair my broken one or spending 300€+ for a new one :/

I have tried the temp root for SO-02K and it sucks, after you disconnect the cable, root is gone, also its a root that doesn't allow you to do anything really. Useless

The purpose of J4nn's root is not to maintain it or end up with a fully open phone. You'd need to unlock the bootloader and install magisk for that.
The point of it is to be able to back up the various partitions and things (eg TA and DRM keys) that unlocking would normally erase -so that they can be restored...

Still pretty useless for our docomo

@Purplearyes , no offense, but the fact that you do not know how to use a temp root exploit does not mean it is useless - it is very useful for others as you can see with other posts in this thread.
Particularly interesting seems to be the post #41 (linked from the OP too), that allows to prepare a setup for root after reboot without need for a PC with adb access.
And it is even more useful particularly for docomo, where you have no other (free) option, as official sony bootloader unlock method is not allowed.
Without the temp root you would not have any way to even try to experiment with diag interface to see if unlock of missing LTE bands could be possible or not.
Unfortunately the exploit is useful not only to us, but also to aliexpress sellers, who use it to cheat us by selling Japan SO-02K model with patched firmware to show itself as G8441 as documented here :-(

These fake g8441, wouldn't they return back the Japanese version if a factory reset was done? Or do they somehow truly modify oem partitions and are able to integrate them on Japanese firmware? If so, how come we can't do this ourselves, like patch the Japanese boot img with magisk and get root??

Fascinating. I hadn't been following that thread, so hadn't realized folks were doing that.
Unless I missed something, your root still isn't for Pie, right? Only Oreo?
So these folks are downgrading, rooting, flashing a wrong partition, then upgrading again? That's a lot of effort! Or I guess maybe they've found some other non-root method.

yes, the temp root is only for oreo
unfortunately yes, checkout my post with firmware version history - you can see there they downgraded to oreo from pie then went back to latest pie - they crafted oem overlays just to make SO-02K appear as G8441 - not nice at all :-(

It is quite clever - it is actually very well done de-bloat of Japanese firmware, plus property overrides to force model to appear as G8441, also switched in TA so that it looks that way even in flash mode. Still not accepting other .sin files than those for SO-02K.
It survives also factory reset.
You can do similar modifications in oem, but that does not allow to get root in pie - they do not patch boot img, only oem. Boot (and system and vendor) partition is checked by verified boot with locked bootloader.

Your explanations and Knowledge were an amazing gift. I appreciate it so much. Boosted my knowledge a lot.
Do you know other amazing tools we can use on a non rootable phone like this xz1c beauty. I use obvs utube vanced, i use button remapper for that extra key funcionality without root, i use grenify and naptime with adb. I de bloated with adb ofc.
Do you know more cool stuff? I wanna squeeze this docomo to its max.
Thanks brother
(on another note thinking about buying a g8441 motherboard but they go over 100 euro and can easily be a fake as you mentioned )

I purchased a G8441 new from ebay and had no idea it was a fake till 6 months later when it no longer worked on the Australian 3g 2100 band. (it worked on 4g for data and still did, but the phone would not work) I had a XZ2C Docomo SO-05K and an XZ2C G8314 that was also a SO-05K that had been flashed and sold as a G8314. I tried multiple things to get the VoLTE working but failed. I loved these phones but purchased a Samsung S10e and moved on.

@Purplearyes , @the baz or anybody else - can you please share me TA partition of your SO-02K (or the fake G8441 which is in fact SO-02K)?
I am on the verge of enabling LTE band 20 on my SO-02K, but I need to compare several TA partitions of that model in order to identify ta units that are device specific vs that are identical within the SO-02K model range.

Forgive my ignorance , but what is the TA partition?

[Q] Xperia Z Bootloader?

Hey guys,
Just wondering if the Sony Xperia Z will come with a locked or unlocked bootloader?
if it is locked, can it easily be relocked after unlocking it for warranty purposes?
I know there isnt much info out right now, but i have never owned a sony xperia phone so,
someone shed some light for me?
Devices from carriers usually can't be unlocked. If you buy it outright then usually it can be unlocked. The process does not record your full IMEI and can be relocked after so you are pretty safe in that regard. My HTC takes the full IMEI (so it can be identified) and if you lock it then it goes to "re-locked" and not "unlocked" .... so the sony method is actually pretty good.
Before buying you can always check on a live unit if bootloader can be unlocked.

Ah okay thanks mate,
hmm new to Sony here too. So what are the chances of pre-orders from carriers being bootloader locked? Just to clarify, does that mean carrier purchased devices are useless (if they are locked)? I was planning to get my device from Orange Uk as i can get a pretty decent 40% off the monthly tariff which makes it the best deal for me. But if it is locked then I may need to pass on this....bummer

Well, if i recall correctly, the verizon droid DNA had a permanent locked bootloader too, but the guys here on XDA found a way to crack it.
who knows, maybe there will be a loophole discovered after the first few days?
I'm currently using a T-Mobile Xperia T, and the bootloader is not unlockable. So I would guess the same for the Z.
Though I think early units are generally unlocked (but don't quote me on that but this was the case with my Galaxy SIII and another guy mentioned this for UK network 3).

Is this just the way sony handles it's bootloader?
I unlocked several different phones which were ordered from a carrier without problem. Depends on the device itself!
But Sony seems to be very developer-friendly. There's a developer site on sonys website, where details about bootloaders are posted. Don't know the exact url atm, I'm at work...
For me it is essential to get a phone where bootloader can be unlocked. My first phone was a lg, without custom rom I would not use it anymore...
It all depends on the country. In The Netherlands all bootloaders can be unlocked, even if it are branded handsets from a carrier.
again as mentioned this is my first Sony Android device so please bare with me. Can someone explain the reasons to unlock the bootloader as from what i've seen people have said u still can flash ROMS with a locked bootloader?

If you're getting any sort of subsidy discount, it's highly likely your device will not be unlockable.
The general rule for Sonys is: If it is sold SIM-locked, you will not be able to unlock the bootloader. If it is sold SIM-unlocked, you'll be able to unlock the bootloader. If the carrier later gives you a SIM-unlock code for a device that is sold SIM-locked, your bootloader will remain locked (Sony is working on trying to change this with carriers).

Sony's bootloader security is pretty strong. If the Z were likely to have a loophole, the T would've probably been defeated by now.

You can cross-flash firmwares for other devices, but you cannot flash anything that has a modified kernel.
Thanks Entropy for your very helpful reply! I appreicate it
In regards to the discount, it is only because a friend works for them and in return are given a discount for friends and family. Otherwise it will be just the same as purchasing it direct from my carrier. My usual experience with purchasing a phone from a carrier, especially a newer phone which has 'just' (first batch usually) released is that they are usually simfree stock (sim unlocked), but heres hoping!
The Bell (Canada) Xperia ZL I have has an unlockable bootloader.
Only stok based roms... cm, miui, paranoid, etc bootloader must be unlocked so you can flash custom kernel
Sent from my LT26i
So therefore AOSP roms cannot run on a Locked bootloader due to requiring a different kernel. Where as variations/modded versions of Sony's rom can be flashed due to not requiring a custom kernel.
I think I understand now. The Sony rom looks decent to be honest which isn't something I can say about Touchwiz. It is actually skinned nicely and I wouldnt mind a de-bloated version of that.
I'm pretty sure sony will unlock it, judging from Sony's recent actions where they released the kernel source for the T if i'm not mistaken. Why wouldn't they do it for this monster phone right?

It's already listed on Sony's "Unlock Bootloader" site. So i guess they'll all unlock, unless you get it carrier branded/simlocked and they ( carrier ) will interfere with unlocking process.

I believe you need an unlocked bootloader to be able to boot the rom?
For htc devices, you need an unlocked bootloader, but it does not have to be S OFF.
If it was S ON, you just had to do an extra process of manual flashing the boot.img through fastboot
This is pretty simple if it's sim locked then it's also bootloader locked. The issue is not if you bought it on your carrier or on a retailer store. It's about locks

Depending on what you mean by "boot the rom" i am assuming you are referring to AOSP roms which use a different kernel to stock roms usually. Thus if you cannot flash a custom rom on the phone with a "locked" bootloader, you are stuck with stock Sony type roms. Don't mind it personally just sucks i cannot experience the great kernels that the XDA devs release. Fingers cross the first batch of pre orders will be unlocked though as they are usually sim unlocked in my experience.

50% true. As Entropy said the simlock can be "unlocked" by the carrier. This will therefore then be a sim unlocked device, but the bootloader remains locked. This needs to be clarified to Sony noobies like myself who may think sim unlocking will result in a unlocked bootloader, or by buying a sim unlocked device from say Ebay they have definately gotten a unlocked BL.

It's different again. With a locked bootloader you can't flash a custom kernel *at all*. I'm on a HOX now so I know all about the stupid htc bootloader unlock It basically means the device is useless for custom roms etc..
Still waiting to see if my local carrier will lock it or not, they have a mixed history with simlocking devices so could go either way. If it is locked I'll just pick get an iphone instead (should be roughly same price on contract) to sell on ebay and buy my sony outright I'll make it work one way or another.

Bootloader Unlock Code - and locked bootloaders

Dear all,
Just as you might already know, not all Xperia Z are blessed with having an unlocked bootloader .... it apparently is something related to the carrier though and not to Sony themselves. As it happens if your bootloader is locked and is NOT unlockable you can still head to the website and get your unlock code by putting in your IMEI.
Now that's weird ...... Now just wondering if the same procedure could be applied to get the device bootloader unlocked ....

Yes true but then again why does the Sony bootloader unlock site still provide an unlock code for locked bootloader xperia z's? This implies that the unlock code is used by Sony technicians to unlock bootloaders ... it's only a matter of determining what that procedure is .... This is definitely being used by carriers.
Really interested to know this for certain, I just got a Z on o2 UK and am a little disappointed that I can't flash any roms. I don't think I can live with stock for ever! Had previously purchased a (dreadful) bootloader locked xperia play which had the 'bootloader allow unlock' set to 'no' which a helpful guy on here managed to change to a 'yes' for the reasonable sum of £10 but this was using testpoint method which obviously won't work on a Z as it's sealed.
If the answer is definately a no to unlocking the bootloader even 'unofficially' then I think i'll have to send this phone back and try my luck with a different phone (an ugly S4 probably). I really do love this phone but I also love being able to change my roms as often as I like to whatever I like.
In the past a bounty would have attracted some devs to work out a cunning plan but if this is not possible at all then theres no point
Anyone know for sure?
Maybe if you change your customization and download a generic cust. ROM, you could probably unlock the bootloader?
If you backup you data and create an ftf for your current cust, you should be able to restore if it doesn't work.
Use the first guide to get an ftf of your stock ROM.
Second to check what generic customization you'd like to download.
Third to change your customization and download & get the appropriate ftf.
Flash the ftf using flashtool.

The unlock code is generated from the imei number I think, so putting in any imei number will return an unlock code.

One guy claimed he done this but never came out with exact step by step instructions so no proof in this.
I previously tried every combination with no avail. as seen in previous threads about unlocking bootloaders we need alot of work done by a dev who knows what he is doing, sony have really tied up the security on these phones.

Well, it was a suggestion, you can try it if you want to.
If it doesn't work, then the only possible way is to somehow flash a bootloader that allows itself to be unlocked and this, I suppose, will require bypassing security.
The bootloader is usually not flashable and flashing an unsigned bootloader is even harder.
Reverse engineering bootloaders requires experience and involves a considerable amount of risk.
And that's only half the struggle. You also need to think about how you're going to flash it onto your phone.

I really would but I haggled a good deal with o2, £12 a month cheaper than what phones4u advertised with a free Z.
I am probably going to send it back though, just a shame as I really like this phone! Could always try phones4u and see if they will offer the same deal. I should have really thought about the possibility of permanently locked bootloader before I ordered it, after all the grief I had with my old xperia play.
So it definately can't be changed ever if it's set to disallow bootloader unlock?

So can no devs lend a hand to this issue. A lot of people with Xperia Z's are affected by this issue.
It's all down to the TA partition. If it contains "bootloader unlock allowed = no" then you are screwed. Trying to modify it or flash someone else's TA results in an unrecoverable, permanent HARDBRICK, regardless of what bootloader or kernel is flashed

bounty hunters, where are you?

Well, it was a suggestion, you can try it if you want to.
If it doesn't work, then the only possible way is to somehow flash a bootloader that allows itself to be unlocked and this, I suppose, will require bypassing security.
The bootloader is usually not flashable and flashing an unsigned bootloader is even harder.
Reverse engineering bootloaders requires experience and involves a considerable amount of risk.
And that's only half the struggle. You also need to think about how you're going to flash it onto your phone.

I would like to point out something. Now I know these two things aren't the same, but I'd like to use it as an example. The Xperia Z's bootloader is locked, obviously lol, I've been modding xboxs and ps3s for a long time, and from that experience I think it can relate to this. Why? Well, from my experiance,on the xbox you can't put a custom dashboard unless you JTAG it, although you can get free games if you flash the chip on the disc drive but that's all. with saying that, it's like saying, you can put custom funcions in the Z but you can't change the ROM. So with the xbox, before you're allowed to flash a custom dashboard, you have to unlock your NAND software, with a ps3 (made by sony lol) you can flash a custom firmware if your on firmware 3.55 but if you're above that, you need an e3 flasher to flash your NOR or NAND chip to downgrade and mod it, one time with the ps3 there was a thing called a E3 Stick, I believe it was called that, i can't remember, and with the e3 stick it wpuld exploit the system cause it was a certain type of board it was build with... So if we'd be able to maybe, find a way to exploit the bootloader, or possibly JTAG it or flash it then I think we'd be able to achieve our goal of putting a custom ROM. The problem with the JTAG or flash theory is that we'd have to open the Xperia Z, so as another theory now, we find a device that we plug into the phone and exploits it to let us flash any ROM we want. just like samsung devices, if the phone gets hard bricked and it doesn't turn on anymore,fried, or if you want to reset the flash count you'd use a JIG to put it into download mode and flash any ROM you want to save the device.
Is there a possible way to unlock on the fly? Like not need a computer? I have the unlockcode

No. The phone needs to be in fastboot mode to unlock the bootloader. The only way to send commands to the bootloader is via a PC.

A71 SM-A715F/DS and A-716U questions

is the unlocked A-716U rootable using magisk and does anyone think there will be development on it(ie Custom recoveries ? One last question one this specific model; assuming root is possible on unlocked would it be possible to get a carrier locked version (cost saving) and reflash firmware similar to oneplus's MSMtool?
lastly is the A71 SM-A715F/DS root-able with TWRP support?
Thank you
ps
I will also contribute to bounties
everyone is going to say/think "search the forum!!!" but unfortunately the posts available dont list specific model numbers when talking about successful root/custom recovery,.
U.S. variants usually can't be unlocked and therefore you can't install custom stuff like magisk patched files.
That used to be the case until recently that a person was offering bootloader unlock as a service to many 2019 and onward devices, as you can see here: https://forum.xda-developers.com/t/sampwnd-usa-model-bl-unlock-info-u-u1-w.4201689/
But, you would have to ask if the A71 is supported. It probably would need to be tested, but the owner of the thread was quite confident that it could be possible.

Oh okay, so there is no MSMtool like with oneplus devices where you can just change to international firmware? If so if there an international 5g version of the a71 (any a-series) with 5G? sorry the model/SKU's for samsung devices is confusing and there is an insane amount of them.

I'm sort of guessing that's the Odin equivalent of Samsung devices, not sure I've never owned a OnePlus device.
You can use Odin to flash different firmware on the device as long as it's the same SoC. For example, I've flashed Galaxy S9+ Unlocked firmware on my T-Mobile Galaxy S9+. One is variant SM-G965U and the other is SM-G965U1. However on this case, both firmware were US. One was unbranded U.S. firmware and the other was T-mobile branded firmware. I've also flashed Poland firmware on my Mexican A71, they're both model SM-A715F on this case.
I don't know if there's an international variant of the A71 5G. I guess you'll have to look that part up on your own. I think there is though.
The MSM tool enable users to take a carrier locked oneplus device and unlock it among other things. can odin unlock bootloaders ?

Not really. Odin can only flash firmware, either stock or custom (you use it to flash TWRP and then basically everything else you flash with TWRP).
And no, Odin doesn't do any bootloader unlocking, any unlocking is done with the device itself. But as I mentioned, U.S devices aren't unlockable out the box.

There is no possible way to do it... for free as of now. If you want to unlock the U.S. variant you have to do it via the paid service I pointed out and thats only IF it works (as I mentioned, its been untested on the A71)
In comparison, you can buy the F variant, turn it on, head to developer settings and select OEM unlock and then unlock the bootloader.
If we ignore the paid service, sampwnd, that I pointed out in my other response then it is impossible to unlock the bootloader of the US variant and therefore, impossible to root.

General [CLOSED][SamPWND] Bootloader Unlock [S21/S21+/S21U - U/U1/W]

Note: This Thread is @svetius Approved!
NOTE: Thread locked and link removed until OP returns
SamPWND Bootloader Unlock Service
It is now possible to unlock the bootloader of USA/CAN Samsung S21 Models!​
Note2: This is an informational thread that links to a paid service. Paid service is not a service provided by XDA.
The service described in this thread is simply to provide a remote service that will unlock the bootloader on USA Samsung devices released from the S10 and newer devices. This includes S10, N10, S20, N20, S21, Flip/Fold models, Tab S7 etc. devices which typically will have the letter U, U1, W or in some carrier specific cases might have a different letter, for example, N976V is Verizon N10! 5G model which is also unlockable. This service is not for Exynos variants or China/HK variants that are already unlockable by default.
Due to the nature of this service, there is no exploit that exists. It is also device specific so it is impossible to release any sort of exploit or method that would work on every device due to it being device specific. I will explain more of the process below but please understand that individual files are needed for me to purchase to unlock your devices and of course that is why this service is not able to be provided for free. You all know from my past experiences and posts that if I could provide a free method I would have already done so.
Spoiler: Process
1. First you should be sure to read the FAQ's and all other information on the website and in this thread etc. then be 100% sure that unlocking is what you want to do. Read the notes/disclaimers, refund policy, etc. etc.
2. If you decide unlocking through this service is what you want to do, proceed to the website REMOVED and in the menu go to the "Purchase" tab.
3. Be sure to read each step clearly and enter in accurate information. Form is designed to help walk you though getting your OneUI version, bootloader version, the correct DID etc. etc. It also includes a brief description of the refund policy as well as a signature box to sign just iindicating that you have read everything and agree. This is also done so that if you are on a device or a specific update/bootloader version that cannot be unlocked then it will tell you so and will not allow you to make a payment or will show 0$. If you can unlock your device, it will show you the price and allow you to make a payment once you have completed the form.
4. It will take 1-2 business days (not counting weekends, holidays, as well as life events such as if I get sick or life happens or my source is not available at the time etc.) to have the payment hit my bank account at which time I will send to my source to obtain your unlock "token."
5. Once token is received, I will proceed to message you on Telegram or Discord (whichever you prefer, you have the option to leave your username for both when filling out the form) and will send Instrucitons in a txt file along with modded ODIN (in case you don't already have it) as well as your unlock token so that you can unlock your device at your earliest convenience!
Spoiler: Notes
I wanted to try and keep the XDA threads short and clean so any notes or FAQ's you have questions for I suggest you view the website including the FAQ's first as well as the support group on TG is a good place to talk to others who have already unlocked or planning to unlock using this service as well as you can ask in this thread as usual.
The "Purchase Form" on the website when filled out correctly based on your device will tell you if your device is unlockable or not so fill that out first and if unlockable it will tell you the price at the end of which you can either pay or not depending on what you decide!
Spoiler: Disclaimers
-IMPORTANT - Do NOT blindly update if you are unlocked already or if you plan to unlock your bootloader via this service. Sammy has incremented the bootloader and updated some devices to OneUI 3.1 which breaks the BL unlock. Devices still on the same rev (i.e. S20 at time of this writing) then you can just flash back an older OneUI firmware and device will be unlocked again. If you update to OneUI 3.1 on new bootloader version then you likely will lost the unlock and can't downgrade (i.e. S20FE on rev2/3, N20 and S21 Models on rev2). That said, there are some devs posting some "safe" update files to allow you to update to latest firmware without losing your unlock so before taking any updates always check in the support group first. You have been warned!
- This method will unlock the bootloader allowing you to use custom firmware, custom kernels and everything else that is allowed with an unlocked bootloader including Magisk root.
- Please read the policies on the website including refund policy. Proceeding with the unlock service assumes you have read everything including the policies and decided to continue with the service.
- This DOES NOT unlock your SIM or carrier/network. it is NOT a SIM unlock.
- This process modifies the steady partition. Therefore if you end up messing with this partition or get another remote service such as combo flash or sim unlock service etc. that messes with the steady partition then you might overwrite the unlock and essentially relock the bootloader. Chances are if you have no idea what a steady partition is then I would not worry about it at all.
- Knox will be tripped. This means apps that rely on Knox flag not being tripped will no longer work i.e. Secure Folder, Samsung Pay etc.
- Once the device is unlocked, if for whatever reason it is locked again then it cannot be unlocked anymore. So make sure that once you unlock the bootloader that this is the choice you want to make and you want it unlocked.
- This service is strictly to unlock the bootloader. It is not a root thread, ROM service etc. What you choose to do with your device after being unlocked is your choice. Once device is unlocked, this thread/service will have served it's purpose. Links to other threads sources will likely be provided in another post just so users who are unlocking will have an easy reference and to keep this thread clean.
Spoiler: Feedback/Complaints
If you have any complaints about the service or want to provide feedback then please do so via PM and/or the contact page on the website or via TG/Discord if we have already spoke there etc. Do not bother the forum moderators with complaints regarding the service itself because they are not affiliated with the service and I simply got permission to post about and talk about the service. I assume this isn't something usually granted but I'd like to believe due to me being a long time member, contributor, developer and moderator that an exception was made. Keep in mind, if this somehow get's out of hand or goes south I am sure I will end up having to delete this thread. Let's not let it get to that point!
Spoiler: Purpose
- This is not a get rich quick scheme or something to make money. Trust me, I wouldn't even bother with this if my purpose was to make money because it is not very lucrative to say the least. There is cost involved with purchasing the actual unlock, site costs, payment gateway fees to be able to accept payments, time and effort to process the unlocks etc. so take all of that into consideration when weighing the cost.
- It has been years since USA models had a device that could be unlocked. I have spent countless weeks researching security since the S8. I released root methods for S8 devices as well as the S9/N9 devices at a later time which took a long time to figure out and that was just a basic root method. I was skeptical at first about this unlock process but trusted my sources and when I first unlocked my device I did various testing and concluded it is legit! At this time no one else knew about it, couldn't talk about it, etc. By word of mouth (until now), many devs/users have unlocked their device using this service. TWRP threads have popped up, some custom ROM threads have started popping up etc. The hope of going public is we get a lot more users purchasing and unlocking their devices (when it otherwise is not possible) and drives the development for USA devices.
XDA is the ONLY place I have published this post and would like to keep it that way. You are NOT allowed to create your own posts in regards to this service and if I see any other posts around this service I will ask to have it removed. You can however link to this XDA post if anyone has questions as to how your device was unlocked.
Spoiler: Website
Note: If you frequented the website before, I have removed the "forum" function from the website since we can discuss everything here on XDA in this thread so there is no need for a forum to be attached to my website any longer. Registration on the website is not required for anything. You can view the shop and purchase the service or view the ROM's section to see some of my SamPWND ROM's and download them etc. if you like all without registering or anything.

I wasn't sure where to ask this question, if I need to go somewhere else, please let me know. I am considering getting my ATT Bootloader unlocked - but I have a question - once the bootloader is unlocked, what happens when therre are new firmwear releases? Are we able to update when new Firmware is released? Or will that return the locked bootloader? Just want to be sure I understand potential issues I might have...
Thanks

It all really depends. Nothing is forever. Only way a update will break things is if samsung updates their security but doesnt usually happen often.
Thaat said, theres ways to update safely so I wouldnt just blind flash updates until its confirmed one way or the other. Usually its important if they increment the BL because then u cant flash older firmwsre.
Welp, I have the desire to get this done sometime soon. I just keep having busy weekends! But I wasn't aware that I'd be able to flash BL update packages so long as they don't relock the BL. Any idea on where I could find out if the next software update contains a BL file that'd relock me? If so, then I'd be doing this ASAP lol.

Thanks for your repsponse to my previous question - Of course, there is no way to know if and when Samsung will update/increment the bootloader, but if I am not mistaken, it doesn't happen very often. That being said, it sounds like as long as I am careful about updating - waiting to make sure the Bootloader hasn't been updated that way which prevents going backward - I most likely won't lose "the unlocked" when I update new firmware.
One last question (probably a dumb one) so if everything checks out with the Bootloader when new firmware is released, I assume that we can just use Odin to flash the updated firmware - is that correct?
- By the way, thanks for your help with this.

Yeah, but each software update has a bootloader update included, hence why I was asking where I could find out whether or not flashing that file via Odin would end up relocking the bootloader... I suppose we'll have to just check around here on the XDA forums to find out whether or not the updates would be flashable whilst having your BL unlocked... =(... So we may have to wait a few months until we start seeing posts discussing exactly that...that is, of course, unless Samsung publicly announces whether or not the BL update will have security changes... But being that I haven't had a Samsung phone for the last decade, I'm not really sure if they'd ever announce that information... But hey, that's the one question that's holding most people back from getting a bootloader unlock ¯\_(ツ)_/¯

@elliwigy Food for thought: Add on service: TWRP Install?
I would feel a lot better about $150.00 if I at least got a free TWRP install. I mean I bought a $60.00 screen protector and got it installed for free. Unlock phone and get free TWRP install. Advertise it as a limited time deal.
Either way I think it would be a great add-on service even if a small fee applied.
How long does it usually take to get a response back? I got the first email like 4 days ago, this is normal?
Like I'm waiting for the unlock code or whatever it is I use to unlock the bootloader, it's been 5 days now?

To you and others who fill out the form:
If you fill it out and it doesnt give you the option to pay or says 0$ then that means your device is not currently unlockable. Hence why you woukdnt get any response from me since I respond to those that are unlockable and have submitted payment.
I dod add yesterday if you are not unlockable itll give you a message saying you cannot unlock at this time to further clarify it.
I will update OP tonight as much has changed since first launching/posting SamPWND services.

Question Just bought this - Question regarding unlocking & root

I just bought this phone. It's actually quite nice and better than I expected. Paid 475€ for it brand new in a store here in Italy. I'm coming from the good old XZ1 Compact, aka the best phone ever made. This seems to be a big (too big, tfw no phone under 5.5) improvement over it.
That being said, I was wondering how does Asus react to their phones being unlocked. I come from Sony which does not like unlocking, in fact on the XZ1 and XZ2, unlocking was permanent and you lost drm keys and stock features fOrEveR. How is it on this one? Does it void the warranty forever? Do you lose stock features after unlocking? Can you relock the bootloader and go back to full stock eventually?
I googled and searched all over but I find conflicting and contraddicting informations about this, on top of the usual ****ty websites with ai generated copypaste guides.
Thanks in advance.

I think so
>>Do you lose stock features after unlocking?
I did not find anything that did not work anymore after unlocking (but I tested only the functionality that is important for me ....)
>>Can you relock the bootloader and go back to full stock eventually?
I don't know if you can relock the phone but I doubt it.
You can reinstall the Original ASUS Firmware and it still works like before. You can also install the updates for the original OS manually (I did not test if OTA still works)

To add to bnsmb's response,
When the phone is unlocked, some apps will not work, like google pay for example, but the bootloader can be relocked with one fastboot command and you will get all features back (except OTA updates from the settings, you will have to update manually)
(It is not recommended to relock the bootloader when not on the Stock Asus ROM)
To relock, simply type these two commands
adb reboot bootloader
fastboot oem asus-csc_lk
reboot
The phone will prompt you to do a factory reset when booting

Yes, I have tried it once, but some people reported it does not work depending on the version, I tried on Android 12 and it worked the first time (and on android 11 but that was the first unlock a while ago)
Thank you for the info! I can't find the official manual or faq though, even from the link bnsmb provided :\
That's why I asked here in the first place. From what I can tell after looking through this info, they will know you have unlocked from the imei, considering their unlock tool talks to the mothership before doing the deed. It is still unclear if they will respect the warranty period even after unlocking. I don't care about asking them for support on an unlocked phone, I just want to make sure it will get repaired or replaced for free (in terms of money and hassle) if I get a defect down the line that is unrelated to the unlock, such as a hardwre failure or assembly defect.
Anyway, it seems the only way to shed light on this mystery is to ask Asus themselves. I will report back as soon as they respond to my questions.
Warranty with unlocked bootloader
The warning text of the unlock app links you to the Warranty Policy for ASUS Phones, where the relevant part reads:
6. Exclusions from this limited Warranty Service
[...]
(m) Unusability or damage to hardware of the product caused by installing and using any kind of the Unlock Device App, which is a utility that will unlock your product’s boot loader but will render the warranty null and void.

So yes as is usual, they will try to use "you having unlocked your bootloader" as an excuse to not repair their broken phones under warranty.
But, depending on your local consumer protection laws, there is a good chance this is actually illegal. In the EU for example, during the 2 years of required warranty THEY have to prove YOU that the defect was ACTUALLY CAUSED by you messing with the phone's software - which generally speaking they can't because it wasn't.
If you haven't seen it i recommend this thread for some details of people who have actually been in that situation - from what i saw after a quick glance through, 3 out of 3 people there got their unlocked&rooted phones replaced under warranty in the end, even it it took some effort to convince the support...

The linked thread does tell that one person was successful with the ASUS support, "all other" unfortunately not, see e.g. post #6.

Reading posts #31 and #38 i am pretty sure the person from post #6 did not have to play in the end as well. I also can't see anyone else in there who reported they tried to get unlocked phone replaced and didn't
Ups my fault, I have not seen the posts after #20 ... So it seems the warranty (given by law) is not void but the guarantee is (given by the company).
Anyway, in the meantime, Asus replied to me saying that if you unlock you lose your entire warranty no matter what. I reiterated, asking if I will also lose my right to a free repair for issues totally unrelated to the unlock, and they said yes, you will lose every right to repair.
So that is the official stance!
Too bad, I'm still in the return period so I might just get rid of it and hunt for a Pixel 5. Kind of sad though, the phone performed pretty well for me so far. But I need muh root and eventually LineageOS...
