Hello, I am trying to switch from an Orange operator rom to a Samsung XEF rom, the problem is that when I flash everything goes normally but the rom does not flash and remains in Orange rom. Yet I have no error message.
[Samsung Galaxy S21 Guides, News] AlphAndroid:
For some reason I can't get it to detect my phone after plugging it in. Odd.
[Samsung Galaxy S21 Guides, News] AlphAndroid:
Does this require the samsung USB drivers?
[Samsung Galaxy S21 Guides, News] BredzProh:
Yes. Windows is supposed to automatically install the drivers when you plug in your phone.

You may also install them by installing Smart Switch for PC.

Is there any reason (that we know of) why flashing an AT&T device to the unlocked ROM wouldn't work this year as it has in years past?

I went from ATT to Verizon without problems. Flashed the Unlocked ROM first and it was fine.

Hello, I'm trying to switch from the Orange operator to the Samsung XEF rom ROM, the problem is that when I blink, everything goes normally, but the ROM doesn't blink and stays in the Orange rom. I need to make a mistake.

I have the same problem I have orx and I would like xez, dbt multicsc rom via Odin didn't help either

Problem solved, via Samkey application, S21 5G is already supported
[Samsung Galaxy S21 Guides, News] sivuha0101:
For people who can't switch between csc in the same mult csc pack. OXM multi csc pack contains all the european generic and network branded firmware (csc) so if You are at SFR (part of OXM multi pack), and flash it with BTU (part of OXM multi pack) the SFR will stay. What you need to do is to flash it with different multi csc pack (just see what packs are available for your model), then flash it back with OXM multi pack, and it should switch to some generic csc, then if you instert your sim card it should ask you if you want to customize your phone to the inserted sim card and it will change your csc to the one you want.

EDIT. It works with other models as well, usually there is a domain language in each multi csc pack, and for flagship models it's usually DBT or BTU, for cheaper phones it's usually a langauge where the phone sells the most so for some A series models it's either ROM or XEO or XCZ
[Samsung Galaxy S21 Guides, News] Alvincp:
Thanks for that!

I am from Brazil and wanted to install my regional stock ROM but everytime I did it, it went back to my carrier's ROM.

What I did in this case was installing an OXM csc (the german DBT) and then trying again with my stock regional ROM (ZTO).

Removed my SIM card and didn't connect to wifi untill I was sure the stock ROM sticked to the phone.

PS: If anyone reading wants a rom from the OXM multipack and is having troubles, try using the Brazilian ZTO stock rom and then go back to yours.
[Samsung Galaxy S21 Guides, News] sivuha0101:
That's true. ZTO is part of a multi csc pack OWO, so it will work for OXM. Good job mate
[Samsung Galaxy S21 Guides, News] mattern1974:
My S21 Ultra 5G from AT&T is somehow not getting updates and seems to be stuck on ATLF firmware with the December 1, 2020 security patch. Called AT&T...they blamed Samsung and sent me to Samsung. Samsung blamed AT&T and wants me to travel 50 miles away to a Ubreakifix store (official Samsung repair center). Today I called again and AT&T had me factory reset the phone with the result being the same - - no update - software is up to date.

Frija seems to be downloading the newest AUC8 firmware when I put in the model of SM-G998U with ther correct US code which I hope is the AT&T rom.

Is the firmware from Frija safe?
[Samsung Galaxy S21 Guides, News] Micalus:
hi there

I have done this recently, perhaps with a slight fail on my sight, since i updated to the latest OXM pack, since i wanted to switch to DBT from DTM (german telekom) without reading this thread and your post first. So my phone didn't switch from DTM to DBT. until yesterday i had to wait for the updated security patch for OWO pack to switch. So all went fine and i switched from DTM OXM to OWO and back to OXM again.

But basically here starts my problem (if it is a problem, not sure yet):

My phone switched not to DBT, instead it went to EUX, which i guess is the generic code for complete EU countries? i am not sure, since i couldn't find the sales code or CSC for this anywhere tbh. i have two SIM prepaid SIM cards from a third party o2 contractor, so normally (i have done it on my Note 10 plus), like you mentioned, it should ask you to customize your phone and switch to DBT, but for me it simply doesn't ask or go to DBT at all. It simply keeps the EUX. Which i would not have a problem with, when i get regular updates with it like i would on DBT.

If anyone could give me a hint how to change to DBT or what i did wrong, i would appreciate the help. If EUX is fine for getting updates, i am also fine with that, if someone can confirm this. on OWO the software updater said please contact a samsung service center, since i have german SIMs in the phone, but with OXM package and CSC on EUX currently it just says "software is up to date" so it can connect to the update servers if that helps.

A short pm would be appreciated or maybe some help from an experienced user (more than me lol) via telegram as well.

Cheers

Mike

[Samsung Galaxy S21 Guides, News] EekSuYeon:
I was working with someone to find a way to remove Retail Mode from our S21 (SM-G991U1 XAA), and when using Odin to flash, we accidentally used the same firmware BL file for every section of the install. Now the phone is stuck in download mode, and we can't find a firmware download with replacement AP or CP files. Only a single BL .md5 file, or a set of files that don't seem to fix the problem. I found a link here on the forums to what appears to be exactly what we need, but it takes hours to download for some reason, and then fails partway through each time. Always at a different point in the download, too. Sometimes it gets to 2.5GB, other times 3.7GB, but never the whole file. That link is over in this thread:

G991U and G991U1 Firmware Links and Flashing Discussion Here

This was the link I followed:

U1 firmware

Any thoughts? Any help getting pointed in the right direction would be much appreciated. !

I installed Verizon branded firmware on a phone. If I install an updated Verizon branded firmware on top of the old, will it reset all the settings, layout, etc or will it function the same as an over the air update and leave things in place? For some reason it shows as having no updates available when using Smart Switch or from within the phone itself and is stuck on firmware ending in AUDB.

Please help.
[Samsung Galaxy S21 Guides, News] BredzProh:
Hello!

You can't flash a different model's firmware. You should only flash SM-G973N firmware.

Try flashing a non-carrier CSC using the CSC_ file (not HOME_CSC_). Back up your data because it will be wiped!

I know this is going to sound stupid but here it goes. Will this method allow me to switch my T-mobile firmware phone to Verizons?
[Samsung Galaxy S21 Guides, News] Furious Froyo:
Yes, but you'd be better off going from T-Mobile to Global, U1. You won't have Verizon bloatware.
[Samsung Galaxy S21 Guides, News] onefastneonrt:
Thank you for answering my question; although I thought all the bloatware is in the USERDATA file. I was under the impression that I could flash the firmware without the USERDATA file and get on Verizon's firmware without the bloatware.

Have you formatted data to f2fs with twrp?

It makes really a big difference.

Now i don't remember if using fire/ice kernel you could also use cache with f2fs filesystem: you have to try.

At first format data to f2fs, then reboot system.

Then format cache to f2fs: if with cache formatted to f2fs tablet bootloops you have to format cache back to ext4.

yeah this game freaks me out men hehe

unbelievable this stuff they put on it

you probably have an universal radio rom and i have an dutch one..

might wanna dump that.. people are still looking for 3G radio for use in the US

about dumping the rom... i see no point... if we need the dutch language one can copy all language files from the device and send it through bluetooth to the pc or copy them to a storagecard and then sync with pc.. the latest rom works fine so far and i think we first have to look what we actually want to update or upgrade or change.. the only thing i would like to see dissappear is this annoying video at the first startup and this noob stuff they put in..

Hi Developers, how are you doing ? I wish you can make ROMs for black shark phones, because the company has forgotten that they have a line called Black shark!

Joyui 11 MP3 is full of bugs and security patch is 05-06-2020!!
[Xiaomi Black Shark 3 Questions & Answers] Jbazt_katuforzs:
They would love to but without the kernel source, it wont be possible.

Bs3 users need to unite and oblige Blackshark to released this expensive phone's kernel sources. Their firmwares are buggy, inconsistent OTA updates, outdated security patches. Seriously if Blackshark's Dev team CANT COMPLY to the user needs, they shouldn't consider releasing any phones at all. Or if they really decided to abandoned a device development after selling lots of units to the world, atleast leave your consumers with the kernel source so the community can make the best out of their crappy promises devices esp if its $500+ devices

This a a complete deception, greediness, lack of responsibility, false promises, all out lies to the consumers/world. I guess that's typically Chinese for you? 😭

They should be sued because maybe they dont want you to change their phone's software maybe because it's their means of spying in your countries. They sold us the hardware and they want full control on the software level for those hardware switches which makes sense. It's like hitting 4 targets with just one stone which is very clever indeed. China prolly will rule the world in 10 years from now 😆.

I regret buying this phone and when anyone ask me for recommendations, i will say "NEVER BUY A BLACKSHARK PHONE"

Hi All

Looking for a best tutorial to follow and the right one for my phone really don't want to brick it, obviously :/. as there seems to be a few versions for the S7

I have the following: S7 android 8.0.0 SM-G930F not sure what else I need to know! I'm in the UK so I assume UK phones come with Exynos cpu's

and as far as I am aware android 8 is Oreo! but when they say Stock Rom I assume they mean the same as what came with the phone the original rom?

if so is there an alternative stable rom without the crap included or is it just as simple to delete every thing you don't want now it's rooted! and does that mean if I reset the phone its back to normal with all the crap included! or is there a way to keep it rooted even after reset! and should anything be disabled I.e prepare the phone before attempting to root like any kind of auto encryption that needs disabling and just one more question :)

if at anytime the rooting process hangs for a ridiculous amount of time when should I throw in the towel! :( and what are the chances of retrieving the phone back to original state! or does a dirty shutdown brick it?.

I started the root process but failed at first hurdle!, followed instructions install Odin3_v3.13.1 but when I connected the phone nothing showed up in Odin? though I will have another go just to confirm I followed it correctly, I'll update this when it's done.

this was the tutorial I followed:

https://xdaforums.com/t/easy-4-newb...g930fd-g935fd-samsung-galaxy-s7-edge.3596558/

I know alot of questions :) I would really appreciate any help and clarification on the above.

many thanks

[Sprint Samsung Galaxy S7 Questions & Answers] Mohamedkam000:
Look pal, rooting the phone is just like being an adult, it means you will get rid of Samsung's "Child Care".

Yes, UK models use Exynos chip, but you have to be sure, look at your baseband version, if it is G930FXXX, then you are good.

ROMs are in two shapes:

Stock-based: These are just like the one you are using, or other Samsung phones does, like Samsung Experience, One UI, TouchWiz. Maybe MIUI and FlymeOS will come into account, as there are ROMs based on them + Samsung's.

AOSP: These are pure Android ROMs, with few modifications to the core, but keeping the UI as close to the source as possible, Google & OnePlus phones come with a near-to-pure operating systems.

Changing a ROM is not risky, as long as you follow the instructions, without any unaccounted improvising.

Before you install a ROM, read the working and bug list, to make sure you are installing something you have an idea of.

You need to install TWRP recovery (or any other one you like), and format data, in order to be able to travel among ROMs and/or root your device.

Formatting is only required because the phone is forcibly encrypted, and TWRP can not decrypt it, at least not for this device.

Rooting is simply about flashing a 5-MB file, Magisk, then rebooting to system, no need to wipe data.

No need to do any additional steps, unless you are trying to hide root from some apps and/or pass SafetyNet.
[Sprint Samsung Galaxy S7 Questions & Answers] CitizenSmith:
Hi Mohamedkam000

Thanks for replying. I'm not confused about why I want to root the phone. I'm just trying to understand the inner workings and the risks as I'm not as clued up with phone OS's as I am windows. I don't care about warrantees or hiding the the fact it's rooted I just want a clean rooted phone free of big brother well inside at least I know you will never completely keep them out but making it hard is a start lol.

Thank you very much for all the above especially on clarifying about the roms and the reason TWRP formats due to encryption nice one :)

My Baseband version slightly different though it's G930FXXU8ETI3 not sure if having a U instead of a third X makes any difference!

and I posted wrong tutorial I'm actually following this one below again not sure if that matters.

https://xdaforums.com/t/guide-how-t...o-stock-rom-on-galaxy-s7-100-working.3840271/
