unlocked, twrp'd & rooted... what now?

I'm not really sure what I'm doing, I changed my country code from "demo" to eu and I'm on EVA-L09C432B182. There's so many different versions and I don't know which is good or even compatible. What would be the next thing you guys would do in order to get the most from my phone?
Edit - I just jumped in at the deep end and everything wen't well, I'm now on Nougat with emui 5.0, if you're in the same boat as I was, I used the Huawei Update in the second post of this thread: https://forum.xda-developers.com/p9/help/p9-7-0-nougat-update-eva-lo9-b182-t3539754"]https://forum.xda-developers.com/p9/help/p9-7-0-nougat-update-eva-lo9-b182-t3539754

I have an eva-L09 with C900B190 and have country "demo" ??
I read a lot of posts how to get from the C900B190 to a Rom that has ota updates.
Before I start and because I am a bit of a noob I want to be absolutely sure I get all steps correct...please help me out and confirm/correct this
1) set develloper usb debugging
2) make sure phone connects to pc
3) install latest twrp
4) unlock boot loader with tool (https://forum.xda-developers.com/p9/development/huawei-p9-eva-l09-eva-l19-eva-l29-tool-t3591358)
5) make note of unlock code
6) use twrp to flash B136 (still have to find zip)
do I get ota to android 7 or I have to flash latest Rom meself (what is the best version for eva-L09?)
After that can I lock the boot loader and stay on android 7 or will the phone reset with locking and revert to android 6 again?
Thanks for helping

Contacted huawei, they were very helpful I will probably go to the service center to hopefully reset my phone to receive updates.
I also asked for an unlock code in case I need a plan B.

Seems I have no warranty (I got the phone from a friend and have no papers or anything) and have to pay for service centre. So I will try unlocking myself...
If anyone can help me out with all the steps in the right order I would be very grateful.

Bricked phone.

Hello, i was given a blu R1 HD prime phone that was bricked by one of my relatives, according to him, he tried to do a format all + download on this phone, which as far as im aware, is a death flag, so i have here this bricked phone, i installed mrmazak's prime 6.1 no nv.zip file on this phone, but it still gives me the TOOL DL IMAGE FAIL, error i've heard a lot about, i also saw him saying "THIS IS NOT THE PACKAGE YOU NEED" in which case i can do nothing but ask, whats the correct package to get this bad boy up and running again? thanks beforehand.
PS: The phone is 8gb/1gb ram ver. was on ver 6.1, amazon before the brick, no OTA's.

For a device that was format all. Will need more partitions than are in that package you tried. Also I have tried to work with someone else who had the 8gb size device, we could not get past that error.
I do recall that the last last person got a new board for his phone and pulled the images from it to share. There is a link in the main thread somewhere. But , well even when he tried to restore his own backup from good device to the one with do error, it did not work.
NVM
I remembered it wrong. He tried to pull it, but could not do it.
Look through this thread. Maybe you can try to follow the advice I gave him, and it may work for you.

Well, from this mess in english, i can kind of attempt to understand that he tried to install v17 backup, and it didnt work due to the PMT CHANGED FOR THIS ROM, then he somewhere got a .bin backup for miracle?, and then silence, i dont know what else you tried suggesting to him since his english was so bad, i cant follow the steps, on another note, got that .bin backup? maybe ill try flashing it with miracle tool and praying that it'll work. Also, which V17 should i use, NVRAM or NONV

There is now a "repair rom" listed in an mtk support group I try to follow. I have not checked it out yet, but maybe it will help. Let me open this on PC to search for the link
this one was labled v6.4 firmware http://www.mediafire.com/file/6kys9896445l5sm/SP_Flash_Tool_BLU_R0010UU_V6.4_Firmware.zip/file
this is labled as a repair firmware http://www.mediafire.com/file/il54pxuvpkargtr/BLU_R1_HD_R0030UU_REPAIR_MT6735.rar/file
I would have you look at those , first i suppose.
if it does not work I do have backups made from miricle-box, but they are not uploaded anywhere right now.

Real appreciated, will keep you updated, if anything works ill post it here.

Alright, i tried the 6.4 rom, it didnt work, i had it already, i also tried to install the "repair firmware" but in the v5.1628.00.000 version of my SPFT it shows me "SP FLASH TOOL ERROR: (8417) THE LOAD SCATTER FILE IS INVALID", then i try on another version (v5.1744 & v5.1804), then tells me STATUS_SCATTER_FILE_INVALID (0xC00300001), i tried the fix copypasting the hashtags and general settings on top for both cases but that didnt work, i noticed the scatter file looks really weird, not like most of the ones posted here or elsewhere, its just a bunch of rows and not organized in the slightest, maybe i need to try using the scatter for my 8gb/1gb ram? since R0030UU is the 16gb/2gb ram's model code
---------------------------------------------------------------------------------------------------------------------------------------------------------------EDIT: Tried mixed and matching the every file from the MT6735 repair firmware with the ones it didnt have from the prime 6.1 rom whilist using said 6.1 scatter, still on TOOL DL IMAGE FAIL

Hello,

next, The preloader on any updated phone has been changed and does not work to flash anymore.
So, what is / was version on your phone , so I can know if it should be able to work or not?

First: If I use Miracle Box Crack 2.27A, can it work? (Would I have to disconnect and connect the battery to start the phone again?)
Next: I unchecked the Preloader because once I leave a brick as a phone to leave marked that option
Version: (Screen OLD, Now is in BLU Screen) (Ohhh I never UPDATE the software, I never use ROOT, I never use debloat...)

Hi Mr Mazak
I had purchased non prime version of BLU R1 HD. I updated to the latest version via OTA. I had my phone rooted with super su and now wanted to try Magisk. After the reboot I had reinstalled the twrp recovery and did a format of all data on my phone. I am trying to install twrp but when I power on my device it is stuck on the boot loading screen. I have tried hold power button and volume down simultaneously and it reboots but gets stuck on the logo.
I tried using the sp flash tool to restore my phone to stock but it did not work. Get error S_BROM_DOWNLOAD_FAIL. 7d
My bootloader is unlocked.
Tried using adb commands but when I connect to the phone and run adb commands it says no authorisation.
If I can install twrp on the device then I will be able to install the rom from rootjunky, not sure if you require more info.
Awaiting your ananlys
Kind Regards

The latest ota blocks the use of sp flash tool. And the kernel exploit used previouls. But now there is new exploit. But you cannot boot so that is mutt point now

From what you say.
1. You had working phone with SU root.

XZ3 H9493

I'm planning to get H9493, 6gb ram model. I'm wondering can i flash the US firmware on it? (for At&t VoLTE)

One thing I wanna ask everyone here: Amazon also sells the 6GB int'l version (H9493) of the XZ3 for cheaper than the U.S. one, and this site seems to confirm that it not only has all the exact same bands one would need for T-Mobile (2, 4, and 12) and prob AT&T too, but also VoLTE. It's also a Dual SIM version too, though I would only ever use one SIM card.
But if the bands are all the same ones we use in the U.S., would we need to flash it with the U.S. software??

I'm not saying I know for sure, but it APPEARS that all the models, or at least the single SIM H8416 and the dual SIM H9493 (both are sold on U.S. Amazon) have the same radio bands. The H8416 that I got off Amazon was supposed to be the "U.S. version" (with warranty), but when I got it, despite the LTE reception status being int'l and not U.S. in terms of looks (4G shows as LTE, 4G LTE shows as LTE+), VoLTE still works, and I definitely am getting all the T-Mobile bands at least (2, 4, and 12). So that is why I'm asking this? It APPEARS that all the models of the XZ3 have the same radio bands again, so yeah.

I don't think you can flash it. The H9493 is a dual sim model (please correct if I'm wrong), and on Xperifirm there is no Customized US version for it.

And since it's a dual sim model, and you try flashing a single sim one, you won't be able to obviously use your 2nd sim. If that's not an issue for you, then I guess you can try it.

Yeah that's the thing, I could care less about using a 2nd SIM. I only need 1 and of course MicroSD card.
So you think it would work then, even though it's a Dual SIM phone?

I read threads on the XZP forum about people flashing the single sim firmware on their dual sim phone. What I've gained from that is the phone will still work, minus the functionality for the 2nd sim, since the modem configs are different. I haven't tried it myself, don't see any harm in trying it anyway.

Ok great! You da MAN iArvee! LOL :good:
Can you explain the process of flashing? How difficult is it? Does it involve rooting or unlocking bootloaders?? God I hope not. lol
I don't have an issue with Sony Companion as I've used it before though. But I'll admit I'm intimidated by anything complicated. I once unlocked the bootloader, rooted, and S-OFF'd my old HTC One M8. It wasn't fun. LOL

It's fairly simple compared to other OEMs. You don't need to unlock the bootloader nor need root. It's as easy as downloading the firmware, repacking it, then flashing it. The easiest way to flash is using Flashtool, however I don't think that flashtool has been updated yet to support the XZ3.
There is another way using newflasher, no need to repack the firmware. Just place the .exe file in the folder of the downloaded firmware and flash. While it's the same as Flashtool, I prefer flashtool because there are settings you can change (if you want).

Ok. That doesn't sound too bad then. And AWESOME on no bootloader or root stuff! lol
But how did you do it then if Flashtool (which I HAVE heard of) doesn't support the XZ3 then?
Ok let's just say I use newflasher. That sounds MUCH easier! lol I'm assuming it's good then for the XZ3 right? Also, what's the link for the U.S. firmware please?
So I connect my phone to my PC.........put the downloaded firmware "folder" into say the root directory of my Xperia, then put in newsflasher.exe into that folder, and double-click on it (exe)? This is what the instructions here on XDA say to do. But it also (Step 2) says something about putting my phone into "flash mode"? WTF is that? lol Do I have to do that? If so, how??
Well, what settings does Flashtool allow you to change? I just wanna see if it's worth it to deal with it if I don't have to. lol
Thanks!!!!!!!

I used newflasher.
That's the wrong link for flashtool. Here's the correct one: https://forum.xda-developers.com/showthread.php?t=920746
You can download the firmware using a software called Xperifirm. The settings that Flashtool allows you to change is keep userdata, basically just flash the firmware but leave your installed apps, documents, whatever is on the internal storage intact (and more settings, but that's basically the gist of the settings). You can do that also using newflasher, however since there's no settings menu, you have to just not include a few files.
Flash mode is done by turning your phone off, then holding volume down while plugging your phone in to the PC. Once the notification LED turns green, that means it's in flash mode.

Oh ok. Then I will use Newsflasher too! No repacking?? I'm IN!! LOL
Yeah I just had a random site for Flashtool bookmarked from a while ago. I'll remove it.
Ahh I see. Well I'd rather just do a clean flash. Less chance of issues. lol
Ok so using PC I download U.S. H9493 firmware folder (please confirm that is best site), and yes I know to find H9493 firmware now, and Newsflasher. Put Newsflasher.exe file INTO the firmware folder, then connect phone (turned off) to my PC via USB WHILE pressing the volume DOWN button until the green notification LED light on my XZ3 turns on. Then let it flash by double-clicking newsflasher.exe, and then after it's done, check log file for any errors, then unplug phone and start it up! And then finally put it through Sony Companion ("Software Repair") ftw for extra assurance. Sounds right??
Will Sony Companion know or detect the U.S. firmware? If I do a software repair, will it vary how it does that by model, or is the process the same for all models? I know you did it but you did it on the U.S. H8416 version. Do I have anything to worry about there? I'm guessing no since all the radio bands & VoLTE option are in all 3 models. But let me know if you think I should skip this or just do it.

Ok so using PC I download U.S. H9493 firmware folder (please confirm that is best site), and yes I know to find H9493 firmware now, and Newsflasher. Put Newsflasher.exe file INTO the firmware folder, then connect phone (turned off) to my PC via USB WHILE pressing the volume DOWN button until the green notification LED light on my XZ3 turns on. Then let it flash by double-clicking newsflasher.exe, and then after it's done, check log file for any errors, then unplug phone and start it up! And then finally put it through Sony Companion ("Software Repair") ftw for extra assurance. Sounds right??
Will Sony Companion know or detect the U.S. firmware? If I do a software repair, will it vary how it does that by model, or is the process the same for all models? I know you did it but you did it on the U.S. H8416 version. Do I have anything to worry about there? I'm guessing no since all the radio bands & VoLTE option are in all 3 models. But let me know if you think I should skip this or just do it.

Basically just leave everything in if you'll do a clean flash.
Download the one from XDA: https://forum.xda-developers.com/cr...xperifirm-xperia-firmware-downloader-t2834142
Sounds right! Just make sure you install the XZ3 drivers. Google Xperia XZ3 drivers. Should be a sony developer link. Yes, Xperia Companion will know what firmware you are on. When you do a software repair, it will just redownload and reflash whatever firmware is on your phone. However, if you flash the single sim version, I'm not sure if that will work on Xperia Companion. Again, you can try!
I'd just do it. It's really hard to brick Xperia phones. If you do something wrong, you can always just reflash again. But don't take my word for it. I've been rooting, flashing, created some mods, and have a lot of experience with Xperia phones since 2014. I'm just speaking from experience.

Ok I'll use your link. It looks exactly the same as what I got but no big deal. lol
Ok I found this for the drivers. Approve? But wait, when do I install them? lol That was never mentioned. So it's an additional step?
Ok. Well I'd be flashing the Dual H9493 version, not single, so it should be fine, right?
Yes I'll just reflash if not working right after completing the flashing process.
Thanks for all that!

The drivers aren't automatically installed (well the right ones anyway) so it's best to install them yourself. Download the ZIP (yes thats the correct link), extract the zip, right click on the INF file, then click install.
Yep, should be fine.

What exactly IS this frankenphone

I recently bought what was supposed to be a "NEW Unlocked" Note 8 from seller on Ebay and when it arrived, I noticed that it was a few updates behind so I connected it to my WiFi and attempted to update it, but I received this error message:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_toggle_sidebar": "Toggle sidebar"
}
I contacted the seller, but they were not helpful at all, so I installed the Phone INFO ★SAM★ app by vndnguyen to research the issue myself. The information the app provided was really confusing to say the least. First of all, the phones settings menu shows that the phones model number is SM-950U (US Market).
The model number provided by app however is SM-9500 (Chinese / Hong Kong Market)
Adding to that confusion, the phone seems to have both US and Chinese firmware components installed on it as shown by the following screenshot:
The CSC codes all seem to point to the phone originally being created for the Hong Kong market as shown in this screenshot:
However, when I checked the phones IMEI number, it comes back that it was originally a T-Mobile phone. Maybe that was just the last carrier that the IMEI was registered to I am not 100% certain about this, but there is definitely something very odd about this phone and so my questions are:
1.) Is there anyway (without tearing the phone apart) to tell exactly what model this phone is (950U or 9500) ?
2.) Why would anyone alter the phone like this / what advantages are there to doing this ?
3.) Is there anyway to actually update this device ?

You could update it with odin. It looks like the update center downloaded the wrong update.

Thanks for the reply, but I do not think this was done by a bad OTA update or anything like that. I think this was done intentionally because I bought a different Note 8 about a month ago from a different seller and it had this same issue so I think this is done on purpose. What that purpose is I am not sure about yet, but I hope someone can help answer that question. As far as using ODIN to update is concerned I first have to figure out what the real model of the phone is so I can flash the right firmware, but thanks again for the reply.

I'm more worried about that phone being a knock-off fake! If it really was N950U it would absolutely not be able to have that firmware on it that's currently on it. Also if you try to install the real firmware it's more than likely going to brick it especially if it's fake because that firmware is just not right. I would immediately send it back and get your money back!!

I doubt it's fake, just had some alterations on it. @mtcellph to see the model of the phone, boot into download mode. It should say.

@MrMike2182
I already got a refund from Ebay and they told me to keep the phone too so I am not worried about bricking it or anything like that.
@SnowFuhrer
This is the information from my Download Mode screen:
It shows the Carrier as TMB (T-Mobile) which would in theory be a SM-N950U model device, but I hoping more for an actual model number so I could be sure. Any other way to get a more definite answer would be welcome.

What probably happened is, They took a broken phone from 1 region and used the parts from another region to fix. Probably board stuff. That might explain why it has mix match info

You might be right, but I would still like to update it if possible because everything else works on the phone.

Most 3rd party device repair specialist would use working parts from similar devices to make a new device and sell it on for a profit.

The Phone INFO app did say it was a refurb which is the reason why Ebay let me keep it, but the mystery still remains. Is it a N9500 with N950U parts in it or vise versa?
Is there any sort of app / software that will work on a 9500 that will not work on a 950U? I did see the thread about unlocking using an app named 835crom.apk that will unlock the BL of a N9500 model, but apparently will just crash when ran on a N950U model, but it's from like 2017 and I am not trying to root or anything like that.
I simply want to update to the latest security patch available for the phone, but I first need to find out what firmware I need to flash to do that. Again any help in this are would be really appreciated.

From what I know the majority of the components used in the Note 8 are interchanged able with the exception of the SOC, motherboards and modems. While both the N9500 and the N950U run on the same SOC, they do not utilize the same modems. Which maybe what is causing your issue.

I really wouldn't flash anything to it period! Simply because you can't flash one hardware piece with the N9500 and then try to flash the N950U hardware piece because it doesn't work like that! If anything is going to work it would most likely be the unlocked N950U1 firmware but I would tread cautiously because if your modem needs N9500 and your board/CPU needs N950U it's just going to mess it up!
Edit: Also about wanting to update just for the security patch, it's highly unlikely that you'll EVER be the target of such security breaches.. Ask around, if you're not rooted it's seriously HIGHLY UNLIKELY!

If you knew what you were doing, you could flash the modem from one firmware and flash the rest from the motherboard model.

Yeah. But you would have to be extremely skilled in doing so.

Thanks for the replies and I don't really understand why this would be that complicated. It's obviously possible to mix & match the firmware on the phone and it still work (minus the non-updating issue) because that is how it is now, but from what everyone is saying it's a lot more difficult then just flashing the right firmware in ODIN, but I do not understand why and would appreciate some clarification on this.
If the hardware on both models is basically exactly the same thing with the exception of the modem and the current modem that is installed is from the US version, would I not just be able to flash the full US firmware using ODIN and call it a day? If not, why?
Right now the Baseband (modem) and Bootloader are both from the US model. The CSC (which could easily be changed later if I wanted / needed to do that) & PDA (which is basically just the android OS stuff) are from the Chinese model. I am far from an expert in this area but it seems that the PDA is the only thing that I would need to change or am I missing something ?
Finally, I should have included that the reason I NEED to get the security patch updated on the phone is because the firmware (CSC & PDA) that is installed on the phone now does not have VOLTE enabled/working on it and in a later security patch it does have it enabled/working & since I would be using the phone on the Verizon network I kind of have to have VOLTE or the phone will not work once they turn off 2G/3G in the near future.

I think it would work with an AP partition(pda) flash. It only flashes system, recovery and boot partitions.

Thanks for the reply & I think so as well because I am just updating the version that is already flashed on the phone and the PDA is what contains the Android security updates I need if I not mistaken.
This seems like it would be a fairly trivial process, but other users have stated it's more difficult than it seems so I'm curious why they have come to that conclusion.
I think I'll give it a few more days to see if anyone else responds before moving forward just to be on the safe side.

How To Guide Carrier/SIM Unlock - Galaxy S21 Ultra 5G SM-G998U & U1 (QualComm SnapDragon) USA/CANADA! - NO ROOT- FREE

Here's a free How-To on how i successfully Carrier/Sim unlocked my Samsung Galaxy S21 Ultra 5G running the NEWEST Android update on bootloader 5 (USQU5BULJ)released in January of 2022 that was carrier locked to Verizon and now fully Unlocked.
DISCLAIMER:
*This does NOT trip Knox or Void your warranty and does NOT require a root or a paid service. **This is the process I took, you may find some of these steps are not needed but for the purpose or recreating my results, I'll be posting my exact process.***This has ONLY BEEN TESTED ON SNAPDRAGON BASED SAMSUNG GALAXY S21 ULTRA 5G SM-G998 U & U1, if you try it on a different model or phone you may (and likely will) receive different results!!!!
You can read more on how this method works to force a carrier update to your device, here, on the Official Android dev site.
Here's what you'll need:
•ANY (activated or not) Sim from the carrier you wish to switch too.(or a way to replicate the carriers cert from one)
•A computer
•Patched Odin
•BOTH the NEWEST U & U1 ROMs/Firmware - theres a full post on these and how to flash them here, Stock Firmware and ODIN Flashing Guide (XDA) or visit SamFW.com, it has both Odin and the ROM/Firmware files you will need.
•(Optional?) Android ADB platform tools (You can find them on the official Android Developers page here or use any ADB software of your choice, fastboot is not required or used in this process. Link: Android Dev Platform Tools (Official)
Step 1:
So let's presume you have a Verizon or T-Mobile carrier locked phone, if you look at your baseband, which you can find in Settings > About > Software Info, you should see this "SM-G998Uxxxxxxx"
NOTE:
It Is CRITICAL that we flash the U1 rom BEFORE putting in the desired carriers SIM, then reboot, let phone fully boot, ONLY THEN should we insert the desired carriers SIM.
Step 1b:
Head over to your preferred site to get stock Samsung Roms (Refer to link above if you don't know where to find) and download the U1 XAA rom and the U rom of the CARRIER YOU WISH TO USE.
IMPORTANT! MAKE SURE YOU DOWNLOAD BOTH THE "U" ROM FOR THE CARRIER YOU WISH TO SWITCH TO AND THE U1 UNLOCKED (XAA) ROM/Firmware.
IF YOU ALREADY HAVE U1 FIRMWARE
I.e "SM-G998U1xxxxxxx" - you can skip to step 2, but I would recommend reading through the next part.
Put you device in download mode (Hold Vol up and Vol down and plug in the USB, which should be connected to your PC and now your phone at this point.)
Flash the U1 XAA Rom, place appropriate files in appropriate places in Odin, when you get to CSC, DO NOT use the "HOME_CSC" use the other.
Leave the rest of Odin settings alone and hit Start, wait for it to finish and reboot.
Step 2:
Once the phone boots, return to Settings>About>Software and confirm the device is now showing the "U1_XAA" in the Service Provider Software Version - it should say something like "SM-G998U1_XAA blah blah blah" - you just want to see the "U1" bit.
Now put in the Sim from the carrier you desire. A pop-up should appear prompting you to restart your device.
! CRITICALLY IMPORTANT STEP !
We will now initiate a reboot, but BEFORE the device fully restarts, we need to force it into RECOVERY MODE, I was able to achieve this by holding the power and Vol Down buttons at the same time, starting to hold them directly after the "Samsung" Logo fades away upon initial restart. If you have trouble getting into recovery, please comment below.
Once in recovery, use the volume keys to navigate to "Clear Cache" select and execute. Now go to Factory Data Reset/Wipe, select and execute. It should be the option directly above "Clear cache".
Once done, go up to "Reboot to Bootloader", Select & Execute.
AGAIN, Very Important step! We MUST interrupt the boot process again and force the phone BACK into download mode this time, so once the phone attempts to reboot, we need to hold the Vol Down and Vol Up buttons at the same time and the USB MUST be already plugged in, essentially it should remain plugged in throughout this process.
We should now be back in download mode and be on "U1" as we have verified in the steps above.
STEP 3:
Now it's time to flash the ROM/Firmware from the carrier you wish to use. Make SURE you have the SIM from the same carrier inserted during this process as mentioned at the beginning. It doesn't need to be a working or activated SIM, just simply one from the carrier you wish to have this S21 work on.
Flash all items from the "U" ROM/Firmware as you did earlier, ensuring to use the "U" ROM/Firmware for your desired carrier as described above. Same deal with CSC here, DO NOT use the "Home_CSC", use the other.
BE SURE that you use the USERDATA file that comes with the "U" ROM/Firmware. Its Critical in order to get the phone working properly on the new carrier.
Start the Odin flashing process & wait.
Phone will Auto-Reboot.....
Done!
You should now be on the carrier you wish to use.
This can be (in theory, test at own risk) replicated for ANY carrier supported by Samsung.
Please comment your experiences/ issues etc below. Don't be afraid to ask for clarity of something.
PoC, results after doing above process pictured in this screenshot.
Good luck.

Hello. I did everything as in the guide. I downloaded U1 firmware for XAA, but for some reason CCT remains on the phone. Also in the step where to insert the Sim, my phone does not ask me to reboot the device.

Have you tried doing a normal reboot and forcing into recovery first, wipe cache, factory reset, reboot to Bootloader, then before full boot force into download mode with your SIM from the carrier you want to go to already inserted and downloading the "U" Firmware for the carrier you want and flashing it? What does Odin and/or your Baseband in settings say after doing above e process?

Thanks for the guide! Is there any chance this process might also work on other phones? I have a Samsung Galaxy XCover Pro that I've been trying to unlock for months. I've called Verizon many times, and they claim they already unlocked it, but when I put another sim in I still get the message "Sorry, your device can't be activated on another carrier's network right now. For help, contact Verizon at (800) 922-0204 or (888) 294-6804 (prepaid plans)."

@Proverbs2 it can be done with a computer, but not with the method listed above. It would have to be done by a professional business that offers SIM unlocking, so it wouldn't be free. If you want to have it done, don't do any more software updates until after it's unlocked

Hmm I have not tried it, but, in all reality, I used this exact same method YEARS ago on my S7 Edge and it worked then. I have not tried it on another Samsung but I'd imagine anything other then the newest flagship would probably be quite simple to fix as there should already plenty of resources available via Github and such. If you take it on let me know, I'll do what I can to help.
If you want to test it out on your device, i see no reason why it shouldnt work if done correctly, but you may have to play with the order in which you interrupt the bootloader and force the update. Even if you have tripped Knox, there is indeed a way to completely disable Knox all together and not get locked out of the device. I did it on the S21 that I unlocked when I was mucking about on the phone. But that's an entire different tutorial and I'd need people to test it on other Samsung devices. But I'd be happy to share that too if you'd like.

Is it still unlocked and rooted? That would make life another easier. We can repair the IMEI, baseband etc. It's worth a go if the phones just a paper weight right now imo. But ultimately up to you.

Thank you! I'll give it a try and report how it goes.

Good luck! Worst case, look up a program called "Samsung TFT Module", just be sure to scan it for viruses and bad code if you have the ability.unless you are able to find the 2022 update of it, you'll have to settle for whatever version is available. It'll likely be old, clunky and out-of-date, half the program defunct, but a few key parts still work, and quite well. Don't forget ADB drivers. Let us know how it goes!

Ok, I tried to follow each step carefully, but I had to make one minor change to the procedure: after flashing the U1_XAA firmware, I had to power off the phone in order to insert the SIM card. (In the XCover Pro, the SIM card slot is obstructed by the battery, so there is no way to insert the card without powering off the phone and removing the battery.) After inserting the card, I booted directly into recovery and followed the other steps from there.
Unfortunately, it didn't work for me: the phone is still locked, showing the same message: "Sorry, your device can't be activated on another carrier's network..." Perhaps that's because I wasn't able to perform that one critical step, inserting the sim card while the phone is turned on. Any suggestions for a workaround?

Have you tried doing a normal reboot and forcing into recovery first, wipe cache, factory reset, reboot to Bootloader, then before full boot force into download mode with your SIM from the carrier you want to go to already inserted and downloading the "U" Firmware for the carrier you want and flashing it? What does Odin and/or your Baseband in settings say after doing above e process?

Yes, I followed the guide. The problem is that when I'm on U1 my phone doesn't ask me to reboot.
