Question S23 Ultra (SM-S918U1) Google Fi - Samsung Galaxy S23 Ultra

Can US model S23 Ultra bootloader be unlocked? My SM-S918U1 doesn't have the OEM Unlock option after enabling developer options. After some searches I tried switching the date and time back at least 7 days and no luck. I also saw on XDA that K0mraid3s-system-shell could work? I never had this issue with Pixel and One Plus. But S23 cameras made me switch

No u or u1 in the US can ever be bootloader unlocked ever

Well don't say never. The united states S9+ S10 Note 20 ultra were boot unlockable.

Now that I have been sadly enlightened. Is there any way I can root or run any type of lsposed modules ?

It's still relatively new and being worked on BUT there are apps being made that allow for more stuff without root. Shizuku is a big one, it gives apps more permissions than regular android by using USB debugging. LSPatch is being developed as a nonroot alternative to using xposed modules BUT very few modules work with it currently. Hex theming for oneui using shizuku to make TONS of ui customization. Swift backup (titanium backups replacement basically) uses shizuku. There are more but there's no current list of what currently uses shizuku that I can find.

I have seen and heard a lot about Hex as stated above. Know some that use it, but I never have. But from what I have seen it's pretty Amazing

What S23 Ultra models are bootloader unlockable? I too have a sm-s918u1 and the option is missing. I might as well return it and go back to my Note 10+ which was able to do this.

It's easier to tell you the models that aren't OEM unlockable
If your model ends with U or U1 it's not unlockable

So if I have one of these models, you are saying I can't root it or install a custom ROM AT ALL??? Its basically a pointless annoying nagware paperweight that I have to return back to Best Buy? Where would I be able to find the OEM Unlock capable models?

Completely never happening unless someone finds a MAJOR security flaw in android, it's not happening by any conventional means ever.
It's the North American models that are locked and can't be unlocked. You'd have to buy a global or international one from eBay or Swappa or somewhere else, even buying directly from Samsung in North America gets you this model.

Supposed I get that one, and I root it. What issues would I run into like with password manager, bank app, etc? What can be done in advance to ensure smooth operation? I don't intend to do anything major, just install some xposed modules.

It depends on the CSC it comes with. CSC is country codes for different carriers that tell the phone software what works and what doesn't in that region. There are ways of changing the CSC as long as there are multiple CSCs on the device to pick from. Also there's several guides on this sub forum and others here on XDA that explain changing CSC

So would the CSC country code have to be set to another country outside of north america for the OEM unlock option to be presentable? If I use another country code will that interfere with my APN and cell networks?

Afaik models that aren't u or u1 won't work on 5g in the states but 4g/lte etc is fine and CSC doesn't affect OEM unlock. That's the extent of what I know and I'm not claiming either as fact because I don't have a non u or u1 model. I'm just repeating what I've read by others experience.

quick question, just got my new SM-S9180. Do you know what the CSC needs to be in order to unlock the bootloader? The current CSC is S91800ZS1AWA6, and the OEM unlocking setting in developer options is non-existing just like on my sm-s918u1.

CSC doesn't affect OEM unlock. Therefore it doesn't affect the bootloader. CSC only affects what features are available in which country (features like Samsung pay, Samsung health, call recording, etc.) Nothing to do with the bootloader.

Ah I see. So basically it just determines what bloatware that my phone comes pre installed with that I will remove anyways.

SM-G965U1 Bootloader: locked or unlocked?

In a few days, my phone will be receiving an OEM unlock option. I tried checking whether my bootloader is locked or unlocked. I've only seen one Google result where someone said Samsung locks their bootloaders. So Samsung locks their bootloaders, right? And if so, is it a royal pain in the ass like an AT&T phone? I've been trying to install a ROM onto my AT&T Galaxy S4 and that has been.....lord have mercy.
This is my first unlocked phone (my S9+). I know 'unlocked' refers to the CARRIER and not the bootloader. But once root options are available, how hard is this going to be for an unlocked phone?
Also, when I look for ROMs, root methods or whatnot, do I have to search for kernels/ROMs/whatever for the Unlocked version or can I use an alternative (like a Verizon S9 and it will be the same).
OEM Unlock no way jose

Enabling OEM unlock doesn't mean you will be able to unlock the bootloader.

The USA G965 phones would have a locked bootloader regardless of if it came from a carrier or not. Searching seems to indicate that because the bootloader can't be unlocked yet then the OEM unlock won't appear (or it doesn't do anything at all).
.
As for unlocking the bootloader I imagine it is a real PITA. I would imagine that any sort of bootloader unlock would probably come around (or after) a root method is found. Now when that will happen is not certain
any progress toward unlocking the bootloader of the SM-G965U1 ? I bought this Samsung phone from Samsung,and would hope that developers are finding some way to cure the decisions that seem to be in place.
Even though it is supposed to be Unlocked, that probably meant only OEM unlocked, and even then I don't see it directly as an option in settings.

"Unlocked" in this context means SIM unlocked. It also means that it is free of carrier branding and apps. It cannot be rooted.

does that mean that the SIM unlock in this version is ALWAYS present, or should the option show up or be triggered in some way?
It is a nice phone, but it is disappointing that root seems out of reach.
Additionally, I don't seem to get as good a signal as I did with the S5 with TMobile CSC and LineageOS, , in the same location in the middle of the city.

It only means that the firmware is intended to be loaded on phones Samsung sells, which would be SIM unlocked (assuming you didn't buy a carrier version from Samsung). There is no "SIM unlock" option or anything like that. The phone is either SIM locked or it isn't, regardless of firmware.
In any case, none of that has to do with rooting the phone, which remains impossible.
Signal strength has been worse for me on S9+ (all firmwares I've tried) than the older S7 Edge I had. Different phones with different hardware. Not much firmware can do about that.

Manually enabling Dual Sim using tasker or programatically?

I have an unlocked UK find X2 pro and I don't feel like going through the switching region process just to enable the dual sim. I already purchased a dual sim tray for this.
So I found this old reddit to enable this manually for a Samsung phone using tasker:
https://www.reddit.com/r/tasker/comments/b0a1o5
Now I would the need the help of someone with a dual sim OPPO phone (probably better if its a X2 Pro) and monitoring enabling the second sim with adb shell settings list system
Any volunteer?
This probably worked on older android and is samsung specific. Chances of this working are really low but I guess someone could give it a try.
But, I did notice if you unlock your phone using the method in "Change region" thread instead of actually changing your region try typing "*#*#4636#*#*", go into "Phone Information" and see if you can toggle "Enable DSDS"

All models of the X2 Pro are dual SIM. Just the functionality has been disabled by Oppo in the EU because of GDPR.

That's after unlocking the phone with the "Sec5.exe" way from the "Change region.." thread right? Not talking about SIM unlocked(international) phones.
The change happens after you select another region not after you unlock the phone using this method so if you wanna keep everything the same you just unlock it without switching to Singapore.
Oh I didnt know there were 2 types of unlocking. My phone is SIM unlocked yes I bought it from an official UK retailer directly.
Would this void the warranty?

You should probably read through the other threads here. We don't know but we speculate it doesn't as it's using oppos own tools to flash official roms.

The problem is, I am not in the UK, I ordered the phone from the UK, but in my country, we don't have an OPPO service center.. :/ So that's why I am asking for a self-service way to do it. I have installed custom ROMs to phones before, I quite know how to do things here and there.
@AnthonyMkD even if there are no actual Oppo Service centers where you live there probably are some sort of service providers/companies which act as Oppo's official service partners and do all the repairs for them. They should be able to do that. It's the same where I live.

Question [SOLVED] Flashing XQ-BC62 (US) with XQ-BC42 (JP), mobile radio disabled

I was able to flash my XQ-BC62 (US) model with the XQ-BC42 (JP) firmware using newflasher. Everything seems to work OK except the mobile radio. The radio is completely disabled (as reported by *#*#4636#*#* status screens), not just unable to connect. The hardware is still fine since flashing back to XQ-BC62 firmware gets a signal again.
Unfortunately I need to use XQ-BC42 as the other firmware images are missing the VoLTE support for my JP carrier and it fails to provision. At best I can force it into data only mode by setting radio to LTE only. The carrier does not support 3G at all.
Extra steps I tried:
- Perform factory reset after flashing
- Swap out the files for the modem firmware from the US firmware and reflash
Has anyone had luck with this, or are there any additional steps I might need to try?
This phone keeps getting worse. I literally bought it to use in the US and Japan. Sony support said it is officially unsupported by all US telcos. No SA 5G, no VoNR, no VoWiFi. Now I hear that it doesn't work in Japan?!
I already know it's close to useless in French Polynesia despite having all the right radio bands.
You can try swapping both OEM-xxx.sin files from the XQ-BC42 firmware folder into the XQ-BC62 firmware folder and flash there XQ-BC62 firmware with that, then you should be able to get VoLTE and modem working at the same time.
If that doesn't work, there are other methods but they will require root access.

So which modell? which provider? comeing form a country where all of these 5G related features are just in development this would be nice to get some further informations on this topic.
VoWiFi is highly likely a provider "problem" - as we have another thread here where these "offical support" statements are at least highly questionable, as we have multiple users here using VoWiFi.

Did you try to get in contact with the japanese carrier asking if they are supporting VoLTE for devices from other markets?
Maybe the easiest way would to switch your carrier at all.

But you will need the profiles for your vendor. One could play around and try to integrate these profiles into your XQ-BC62 Firmware and see if this would work out. But well - keep fingers crossed that you don't brick anything.

No, they don't support overseas models. I don't know if it's ignorance around the security or an attempt to prop up their own phone sales. Both are honestly believable over here.
This is the only reasonably priced major carrier plan with unlimited international roaming included (ahamo from NTT Docomo). Not being able to use the 1 iii sucks but I'll just write the 1 iii off if it can't be fixed and continue using my JP variant 1 ii.

Why did you get yourself the "American" Variant? Docomo has, as well as softbank, there own supported devices. Kind of similar to TMobile US. Sounds you are spending most of the time in japan. I know that the Docomo version isn't so well supported regarding updates though ...

I have the US model - the same as this thread topic.
It's Sony tech support themselves that told me that there is no carrier support for the US model in the US. It was such an incredible conversation that I saved it. An excerpt:
(Adrian) said :I'm asking you this because at this moment Verizon is currently the only U.S. carrier that supports 5G on the Xperia PRO model. The 5G network service is
not currently available in the Xperia 1 III model and this is why you're getting that
issue. In this particular case we recommend you to check with your phone carrier
if there is a way for them either to provide a different network service or if there is
a work around on their system for you to use your Xperia phone with their service

Don't repeat Sony's claim about 5G being in development. T-Mobile has been running SA 5G where I live for nearly 2 years. I've done side-by-side comparisons between an older phone with SA 5G and my Xperia by swapping the SIM. The XPeria has a lot of "no service" problems because it's using SA 5G channel aggregations without having SA 5G. There's another thread on this - Sony has explicitly disabled SA 5G on all US NR bands. https://cacombos.com/device/XQ-BC62
The Sony phone was unstable roaming in PF and could not see several 3G, LTE, and 5G bands that were available to it. Again, an older phone worked better. I used a much more modern coverage map than your 2017 document.
I haven't been to Japan with this my Xperia yet due to COVID restrictions, but I normally spend ~2 weeks a year there. I know my old phone works well there so I'm going to be mad if a new Xperia is stuck looking for old 3G cells that only exist in subways.
I have an XQ-BC42 that I'm using in Europe with 5G working (which isn't supported officially).
All I had to do was flash the XQ-BC42 firmware with the following 3 files replaced by their equivalents from the XQ-BC52 firmware:
* modem_X-FLASH-ALL-4BA8.sin
* modemst1_X-FLASH-ALL-4BA8.sin
* modemst1_X-FLASH-ALL-4BA8.sin
So in your case you just have to take the 3 files above from the XQ-BC42 firmware and combine them with everything else from XQ-BC62 firmware and flash that.
From what I've gathered, assuming your phone has XQ-BC62 firmware on it already, it might only be necessary to flash the XQ-BC42 modem files and nothing else, but I haven't tested this.
I'm assuming you can swap other files too but what definitely didn't work for me was the oem .sin files from another model's firmware. I don't know if there's something incompatible about the XQ-BC42 compared with other models but using non-XQ-BC42 oem .sin files disabled my radio completely.

no, i am not saying it is under development. The standards are there. How ever - in different regions some of the 5g is still not rolled out / will never been seen (mmWave,SA 5G - at least for private customers).
Well i read the message you quoted a bit different - and i would love to know what other carriers have to say about that.
I personally would find it completly unlogic to sell a device like the Pro, which is said in your excerpt, to have 5G support on Verizon - but then sell the 5G capable phones which have this deactivated at all.
Supported Major U.S. Carriers: Verizon (5G), T-Mobile (4G), AT&T (4G)*
*As of 9/27/2021, please consult with your network operator to ensure compatibility with their network.

Might be, that t-mobile is using some more advanced features. how ever: here where i live most phones up to now don't support 5G SA, at least thats what the carriers say, as there are updates needed to make this work. So we will see here some selected phones using 5G SA - as the providers are working together with SOME of the major OEMs.
You can know ask who is responsible for supporting 5G SA or providing updates... As much as i got from t-mobile usa, they where always not really open to devices, which they don't sell directly ....

sad to hear - but just out of curiosity:
Why did you get yourself the "American" Variant? Docomo has, as well as softbank, there own supported devices. Kind of similar to TMobile US. Sounds you are spending most of the time in japan. I know that the Docomo version isn't so well supported regarding updates though ...

I happened to be in the US at the time to pre-order and it wasn't clear that Sony would release an unlocked dual-SIM model for the JP market. I checked the radio bands before purchasing but all of this client provisioning stuff is new to me. Seems like all these laws were made to force carriers to unlock their phones / allow any standards compliant phone on their networks, and then they find this loophole with provisioning that requires more than just a SIM card...

You can try swapping both OEM-xxx.sin files from the XQ-BC42 firmware folder into the XQ-BC62 firmware folder and flash there XQ-BC62 firmware with that, then you should be able to get VoLTE and modem working at the same time.
If that doesn't work, there are other methods but they will require root access.

Unfortunately this didn't work. But I did learn that the radio problem isn't an issue with the firmware itself.
Immediately after flashing the mobile radio was OK and I could use it with my alternate SIM card. As soon as I inserted the JP SIM card it triggered OMA client provisioning and killed the radio. After this happened not even the US SIM card would work anymore, and any radio related configurations can no longer be changed.
My hypotheses at this point are either (a) the client provisioning step found something off with my phone and forced it to lock down (not sure if client provisioning has the authority to do this though), (b) the client provisioning is interacting with the modem firmware in a JP-specific way and the US modem firmware is borked by this.

I have an XQ-BC42 that I'm using in Europe with 5G working (which isn't supported officially).
All I had to do was flash the XQ-BC42 firmware with the following 3 files replaced by their equivalents from the XQ-BC52 firmware:
* modem_X-FLASH-ALL-4BA8.sin
* modemst1_X-FLASH-ALL-4BA8.sin
* modemst1_X-FLASH-ALL-4BA8.sin
So in your case you just have to take the 3 files above from the XQ-BC42 firmware and combine them with everything else from XQ-BC62 firmware and flash that.
From what I've gathered, assuming your phone has XQ-BC62 firmware on it already, it might only be necessary to flash the XQ-BC42 modem files and nothing else, but I haven't tested this.
I'm assuming you can swap other files too but what definitely didn't work for me was the oem .sin files from another model's firmware. I don't know if there's something incompatible about the XQ-BC42 compared with other models but using non-XQ-BC42 oem .sin files disabled my radio completely.

Other than the issue after provisioning the OEM files from the JP model did work for me. If (b) is true then flashing both the oem and modem files might be a solution. I'll give that a try!

Same result, no radio after client provisioning runs and it stays borked even with the SIM card swapped out.

Have you tried with only the modem files taken from the XQ-BC42 firmware? Might be worth a shot.
Also, it might be worth asking on the 5ch thread if you speak Japanese.

I spent a few more days trying various combinations of flashing, factory resets, etc. and finally have it working. I don't know if this is the only way to achieve this, but I can share the sequence I did most recently. This was inspired by the discussions in that 5ch thread - thanks for the link!
1. Install JP variant ROM with full factory reset.
2. Install the JP SIM card and wait for provisioning to finish. The radio stops working at this point.
3. Create and flash a hybrid ROM, using the modem*.sin files from the JP variant and everything else from the original (US) variant. Do NOT factory reset.
4. Set the correct APN (sp-mode.net for ドコモ).
After this both the JP and US SIM cards are working.
@cjmovie
Congrats on this achievement! Hope you can now use your device as you wished!

Question Motorola Moto G power 2021 verizon need help to sim unlock

Hello everyone,
First i want to thank everyone at XDA Forum community for being a great resource of information and providing great community support.
I purchased Moto G Power 2021 (Android 11), locked to verizon. I am trying to unlock it to be used on other carrier such as tmobile and for traveling. I came across websites that sell the unlock code.
However the problem is when NON-Verzion sim card is inserted in the phone, its does not ask for sim unlock code. Therefore not sure how to carrier unlock the phone.
If someone has insight how to go about network sim unlocking the phone, that will be very helpful and greatly appreciated. thank you
i'm in the same boat
Verizon is a cdma network and boost is a gsm network. The radio files included in your Verizon firmware probably aren't capable of connecting to a gsm network as the two networks operate on different frequencies and I assume employ different connection/communication protocols. You MIGHT could flash the firmware from boost for the same model, but even doing that could be frought with problems like if the boost firmware is older then anti rollback protection wouldn't allow it to boot when flashed, and I'm not sure if the Verizon and boost versions have exactly identical hardware, which could cause massive problems even if it did flash and boot. For example, this model phone has like 3 different touchscreens and using a firmware with the wrong touchscreen drivers would render the touchscreen useless. If you're determined to carrier unlock, be ready to do some serious digging and read everything you possibly can before doing anything that could have irreparable consequences. Best of luck
mine is a cricket, I'm trying to go to T-mobile, same protocol, just don't want to pay the extra $$$

What's the model number of it?
I'd imagine you maybe could flash the firmware for the carrier you want to switch to using the fastboot flash method, the rescue tool will only flash your phone's official firmware. But you can download different builds for different carriers off of lolinet and if they don't work you could flash the correct firmware to get back to where you are now. You might flash your official fw with the vendor stuff from the other carrier's rom if flashing the whole firmware doesn't take or isn't compatible in some way.

Hello thank you for your advice, unfortunately i don't have much experience in flashing different firmware. Also i think it causes too many problems, which are difficult to fix. Therefore i was hoping if there is a way or hidden menu i gotta go into will activate the phone to ask for unlock code when different sim in inserted.

Tmobile is much cheaper in comparison to other carriers. I think once the phone is unlocked it will work pefectly.
When you insert a non-cricket sim card does your phone ask for network unlock code?

yes, it does. it is network locked and "not eligible" for unlocking.
I called Cricket, but they won't unlock it because it hasn't been on their network for the six months they want.
I bought the phone really cheap on ebay for its long battery life., it's damaged (bent as if someone sat on it) but works fine, no cracked screen or anything else. I want to use it on my T-mobile account.

it does not ask for a PIN to use it like a tablet.
I need it network unlocked so I can use it with different carrier.
i downloaded the RETUS rom, i'll try to flash it and see what happens

I believe the issue of why it's not asking for unlock code may be two fold. For one, since you mentioned you bought the phone locked to Verizon, was it purchased from them or was this a second hand purchase like ebay/FBMarketplace etc? Because either way you'll have to meet the carrier minimum requirements for unlocking a device, the former scenario of you having bought the device yourself being much easier to deal with than the latter case.
Second, as was mentioned here earlier, you may be dealing with different hardware. I'm not sure if the G Power 2021 all contain the capabilities to run all network frequencies or not. But if it's hardware restricted or dissimilar to other models in kind based on network carriers & OEM agreements, you might not be getting the chance to input an unlock code because the third party SIM inserted may simply have no way of being recognized by the device, either from a software vendor blob limitation, a hardware radio restriction or lack of capable hardware, or both!
I know this is an old one, but was a solution ever found? Currently stuck with Moto G Power 2021 as well, locked to cricket. It doesn't prompt to enter a code either.

Only free solution is to meet all of Cricket's requirements, and have them do it for you. Otherwise a 3rd party company can do it, for a fee

That sounds better honestly. I'm open to using a 3rd party company, but point me in the right direction if possible. I've been looking, but no idea what service to use if the moto g power isn't asking for a code.
EDIT: Actually, I finally found someone at a reasonable price to do it, and it worked, phone unlocked. They used USB Redirector and did their thing. Took all of 10 minutes. Now I just need to flash a different rom to rid myself of the cricket bloatware.
Have you tried another sim card in your phone, I'm pretty sure these all come unlocked by default. Mine was bought at US Cellular & I'm using a prepaid Verizon service by simply throwing the new sim card in the phone. It works perfectly as it did with US Cellular with no setup or changes required. I believe all moto g power phones do this I had a regular moto g power not 2021 that was on Verizon I switched to straight talk the exact same way.

Actually, another random question, but is there no way to update without unlocking the bootloader? LMSA? Just making sure.

Question S23 ultra Verizon

I'm curious if anyone knows the compatibility of a US Verizon s23 ultra and T-Mobile's network. I assumed they would be compatible as long as its carrier unlocked however I'm having issues getting my Verizon s23 ultra to accept my t-mobile sim. Any insight from someone with more experience is welcomed.
Verizon locks the phone for 60 days. After that, you're good to use whatever SIM you choose (you may have to flash the U1 firmware to get all features working though).

Its unlocked I manage about 40k in devices so they unlocked it for me without much hassle but they cant answer why my t-mobile sim isnt working.
That sounds like it's still locked to me? Are you using the pSIM or the eSIM? There have been some reports recently that the pSIM gets unlocked and the eSIM remains locked to the original carrier but if you're trying to use the pSIM and they say it's unlocked, I don't know.

The esim is verizon and the psim is t-mobile. Ive had small issues in the past with devices not being able to take full use of the network etc. but not flat out not working.
