SJR is the old unlocked for Canada on W, XAA is unlocked for US using U1, thats why they said to use XAA and not SJR because SJR doesnt exist for U1, only W. But now Canada now uses XAC for W. So, TL;DR, use U1 XAA for US, or W XAC for Canada.

I'm actually running U1 XAA on my W S21u because Canada gets super slow updates. Only issue is that Canadian 5G doesn't work on U1, Bixby alarm only reads Fahrenheit, no way to change it in any settings to Celsius, and Samsung Pay requires a Zipcode but we use Postal Codes in the frozen north. There's a workaround for that last one but it still has its limitations using U1 in Canada so W XAC is preferred for the majority as you lose 5G and the metric system with Bixby lol

Thats one message I got when I was trying to do this with my A52 5G. I have an Indian version and want to Flash Canadian firmware. Model is SM-A52F and i loaded SM-A52W firmware.

Thanks a bunch Ben; this really is very useful; finally I'm. able to get rid of the bloatware on my phone; and it is way better in terms of performance without the bloatware. Have a a great holiday.

worked great for me in October of 2023 .. purchased a "W" version of the phone from amazon, needed it to be "U1" version for use on AT&T in USA, got it flashed and it's working perfect.

Thanks a bunch mate, worked like a charm.

Can't be soft-bricked if you flash HOME_CSC but in the most cases you have to hard reset it so it's the same. When cross-flashing must be wiped (backup first with SmartSwitch). Great video 👍

Helpful vid, man. Thanks.

If you flash the XAA version for that phone you will receive updates directly from Samsung, however it is no longer debloated from factory. Since OneUI 4.1, Samsung made it so when you insert a SIM, it will preinstall the carrier bloat, so your CSC will change to whatever SIM you're using. But, updates will still come directly from Samsung over the air like normal.

They did, U variants get updates from the carrier, U1 get updates from Samsung. And W do both. If a W varient CSC is XAC, you will get the updates from Samaung. If the CSC is anything else, it comes from the carrier. But all of them auto switch now as soon as you put a SIM card in. For me, I'm running a W variant with XAC CSC on Bell. So the firmware in settings cha ges to BMC, but the updates still directly from Samaung because it's BMC on XAC firmware. It's kind of confusing but basically you only want two firmwares. Either U1 XAA for US, or W XAC for Canada. You also need to use Patched Odin to flash it because it changes the default model firmware and official Odin will fail to flash EDIT: The difference between W and U1 is that W does not use mmWave 5G, only Sub6 cause Canada doesn't have mmWave. And Bixby is metric. So Bixby will read weather in Celsius, Bixby alarm reads in Celsius, and Samsung Pay can recognize Canadian Debit Visa's. U1 has mmWave, and Bixby is Imperial. Canadian credit cards still work on Samaung Pay with U1 but not Canadian Debit Visa cards.

But as long as it's working, you're good. Bloat doesn't get installed from OTA but if any Samsung update bloat. So like, Samsung apps can be bundled in the firmware updates, so you might get Samsung bloat but there's no way to avoid that. However, you could use ADB to remove them and it won't come back after updates cause the phone will already know it has it, it's just uninstalled for the user account and won't force the install again.

@@frozennorthproductions Thanks a lot for the reply. The purpose of this was to 1) remove the Verizon bloat; 2) change CSC so I could use this phone in case I travel to Asia. So I did choose CSC, not HOME_CSC, to flash. What I guessed was that the version 5 firmware has blocked what your tried to do. If I flashed newer 3 or even older 4 firmware (in stead of the latest 5) and converted the CSC first, then either flash to the latest or let the OTA to take care of it, then the result could be different. But now I am on 5 and can't go back to earlier version. Do you have any new idea to change CSC if you're in my shoes? I watched your newer video "stop Samsung update", I hope your problem has automatically been resolved with the latest firmware.

Hello, I bought an s21 ultra from my friend. It has a tmobile branding. I would like to install a pure firmware now. Will I then also get updates for the future or do I always have to install the firmware manually? and do I lose my guarantee after the firmware flash?

No, one you convert it over it's OTA just like a normal phone, all this does is remove carrier bloat by using the unlocked firmware from Samsung

So I received a refurbished S21+, it is unlocked and all but it has AT&T bloatware and I can't update to oneui 5.0... I live in italy but this phone comes from Germany and apparently has a US AT&T firmware (SM-G996U). I wanted to flash to SM_G996B with ITV, which is the italian version with android 12 and oneui 4.1.1 is it safe to do so and then get the android 13 update the standard way? Could I straight up get android 13 and oneui 5 flashing the most recent rom or is it even worse?

this is a great video but i have a few questions: 1. can i use the same method to install vanilla android from google instead of Samsung? 2. Would doing this process and installing either Samsung or straight android, does the phone retains 120 refresh rate at the highest resolution?

Android ROMs don't work like that, you would need an AOSP ROM for an S21 Snapdragon and an unlocked bootloader before you can make that work. So, the most vanilla Android ROM would ve LinageOS but because these phones have a locked bootloader, they don't make an official version. You would have to use the paid service by a developer on XDA, and then flash TWRP through ADB, and then using TWRP you can flash the unofficial Linage OS. Which WILL have tons of issues, won't have the same image processing for the cameras, and possibly be locked down to 60Hz unless there is an open source driver that supports these displays. Running an AOSP ROM on any Samsung is hit or miss, because Samsung uses proprietary drivers for all of the hardware, so you would be better off running stock debloated, or SamPWN, which is a ROM created by the same dev that offers the unlock service on XDA

@frozennorthproductions

I'm really not too sure, it's hard to pin point without diagnostics. Best I could say is just try it at a friend's place and see if it still disconnects. If it works fine somewhere else. It's your router. If it still drops connection, something is wrong with the phone, or possibly just a bad update. Which you would just need to install the latest firmware, factory reset, and don't restore a backup so all wifi settings are untouched and see if it's fixed.

I bought a Samsung S21 Ultra renewed, right now it uses Verizon's firmware and I want to flash it to stock Samsung to remove the bloatware from Verizon and get rid of their stuff, as well as to have updates quicker. The sim is unlocked so I'm able to use my ROGERS sim card just fine but I just wanted stock Samsung. Would this work to do that and what firmware should I use then. Also would this work for the latest One UI or is it only an old version of Android. It is the SnapDragon Version, My model is SM-G998U.

The SM-G998U1 AXX is the unlocked version from Samsung if you buy it directly from them. It works on all North American Snapdragon phones, and some Global Snapdragon phones as long at the radios are the same. You just have to Google what bands and frequencies your carrier uses, and compare them with the US bands and frequencies that the U1 model uses. If they are the same, it will work, if they are different, you won't have full cell coverage

Are you using the standard Odin or Patched Odin? You MUST use patched Odin when converting between device variants. Regular Odin is only for updates of the identical device and nothing else.

Жыл бұрын

The last part of the build string is what you wanna pay attention to. U5CVG9 and S5CVF5. U5 and S5 is the bootloader version. Once updated, you can not downgrade. So which ever one is newer is where you will be stuck. If U5 is newer, S5 won't even flash, but if S5 is newer, you can flash it with patched Odin, but you won't be able to revert back. As for the last four, that's the build info. So C means One UI 4.1, V is the year, so 2022, F is the month, A is January, and L is December, so that's from F, or June and the other build is G which is July. So the U1 XAA build us a month newer. The last part is just the build revision, so 1 to 9 is revision 1 to 9, and A means 10, B means 11, and so on. So 9 is obviously revision 9 and 5 is revision 5. So Verizon U5CVG9 is One UI 4.0 2022 July Build 9, Official S5CVF5 is One UI 4.1 2022 June Build 5. So Verizon is newer by a month. The official version probably got hauled because of One UI 5.0 Beta

So what does this mean?? I bought an S21 Ultra directly from Verizon. Am I able to change the firmware or not at all? If I'm able to, will it void warranty? I just wanna know because I want to get the one ui 4 beta when it comes out
