Samsung S20+ Missing Bootloader - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

Hello
I just got an S20+. I want to install Graphene or whatever, I want to at least be able to remove google and other crap. I have read it is not possible on the snapdragon models in the US, but most of those posts are old from 2020... I have also read it is possible. I have read there is a paid service that can do it. Can any pros tell me what the deal is, because nothing ive tried works and Im trying to decide to keep the phone or just send it back at this point. If I have to use a paid service that wants $75 then I'm better off getting a more expensive phone and not paying...
My old phone took a bath and I had to wait several days for this POS to arrive so any help would be appreciated.

What is your baseband version?
If I recall correctly, you must be on v1 bootloader (pre Mar 2021 security update) in order to be able to unlock.
See this thread on how to unlock the bootloader (paid service):

Have a look at the above. This may provide you with some guidance.

no OEM Unlock toggle in dev options
as stated in the title on my s20 plus (SM-G968W) there is no toggle for OEM Unlock, its been a long time since ive tried to root and from what ive been able to pick up from googling is it may not be supported for my country or cpu manufacturer...

Frequently Asked Questions
Q: How much does FunkyHuawei cost?
A: You need to buy credits on the FunkyHuawei website. The price per credit varies depending on the number of credits you buy. Different operations cost different amounts of credits. However, the Root feature of the Mate 10 tool is free, and as mentioned above, Recognized Developers/Contributors of XDA can ask for a free credit.
Q: My phone is bootloader locked, and FRP locked. My bootloader unlock code dosen't work. It won't boot. eRecovery doesn't work. Can you help?
A: Yes. With the Mate 10 this is now a common situation. Contact FunkyHuawei for help in this situation. We'll need to access your computer remotely and the procedure is a little bit complicated, but the phone can be unbricked.
Q: I can't get my bootloader unlock code/don't want to unlock my bootloader, but I want to change my phone to something other than Chinese. Can you help?
A: Yes. Our new FunkyHuawei Rebrand Tool works on recent Huawei phones (Sorry EMUI 8.1 phones not yet supported. Coming soon), to rebrand them to another region even when the bootloader is locked.
Q: I'm not seeing the latest version listed on FunkyHuawei or elsewhere as an OTA. Why not?
A: Huawei has a very odd and unpredictable way of rolling out OTA updates. You can use FunkyHuawei to install the new version immediately, or can wait for the update to be rolled out. It might be a month or more after release until the update reaches your device from Huawei directly. We have no idea why.
Q: Why isn't FunkyHuawei free?
A: Because many of FunkyHuawei's features cost FunkyHuawei money to provide. Features that don't cost FunkyHuawei money to provide, like rooting the Mate 10 or our TWRP build for Mate 9/Oreo, for example, are generally made available for free. There are also bills to pay, kids to put through school, and so on.
Q: I noticed FunkyHuawei in an XDA Portal article!
A: FunkyHuawei loves XDA, and is cooperating with them as much as possible. Recognized Developers and Contributors on the XDA forums are welcome to claim a free credit from FunkyHuawei as well.
Q: I have a different question.
A: This is what this thread is for! Post away!

The music transfers to my music app but will not play on my p20 pro with the message “failed to play the file”
Help!
I have a german P20 EML- L09 -
Do i need do a rebrand to another firmware to have Dual sim? Which firmware I need?
How many credits i need ? (or can i do it for free)
I have an English P20 EML-L09,
Is it supported for enabling dual sim fuctionality?
It works!!!! P20 rebrand and mono2dual modified. European FW *.132a ....
Yeah the conversion to dual sim works but you lose the volume in your speakers. Nobody tells you that.
So I am now left with a phone that I can only use with headphones for media playback.
So happy now /s
Also, can't do anything about it because now my bootloader unlock code no longer works, and the generator on the Huawei page gives me the same old code.
Team FunkyHuawei, any help?
You're right. Not silenced at all, but the sound starts normaly loud, then goes to very low. Ringer too. But funky Hawaii tells me that they never heard about that issue ???. All should know. Almost for european c432 release

Back to mono sim? (With funkyhawuei method)?
Yeah.
No can do, you need unlocked bootloader. If yours is still unlocked, good for you, try it, it might help. Otherwise...
Last effing time I buy Huawei. Can't even sell it now. The amount of frustration is just not worth it. Not to mention the amount of frustration just to get the latest OTA updates, just having to rebrand or stay with old software for half a year.
No answer from Funkyhawei people. . No advise on their site about this issue!!! frustrating.

[question] how can i rebrand my honor 7x to international version ?

Hey There Guys,
Can anyone please guide me how can I rebrand my Honor 7x (BND-L31) to international variant....
Please Help as I haven't got a single update on BND-L31...
Rebranding is not recommended. Lots of things can go wrong in the process. I say you should flash a ROM, it will always have the latest updates.
I recommend OpenKirin's ROMs, especially LOS.

I surely understand the dangers of rebranding as I've done it before to my P8 Lite but I want updated EMUI on my phone and the variant I own [BND-L31C185D002] didn't even got EMUI 8....
I'm in a similar situation. I just got a BND-AL10 that I'm trying to turn into something I can use in the US. Can't get a bootloader unlock code apparently, I missed it by like 3 days. Am I the proud owner of a $200 brick?

Well, I have my bootloader unlock code. As soon as I knew about discontinuation of unlock codes from Huawei, I requested mine but I haven't unlocked my bootloader yet.

This hwota-bnd has rebranding process in it. Don't remember which oeminfo files are included. Take a look. If other oeminfo files are needed perhaps we can get them.
**Edit
Just looked again, the eominfo file for c185 is not there
https://forum.xda-developers.com/showpost.php?p=77134788&postcount=6
But maybe before rebrand, try to install the c185D001 version

I'm also in the same boat. Bought a BND-AL10 from India and not even the 3G or 2G bands of Tmobile is working here in US. I contacted Hawaii several times asking for the unlock code but they don't bother even to listen (for obvious reasons). I managed to unlock the boot loader by paying $5 in dc-unlocker. (google and you will find it but I'm not authorized to post the link here). Now I have the unlocked bootloader but I'm still searching for a solid answer if I can flash another ROM (such as the US version of 7X, Mate SE) on my device without bricking it. Please let me know if you have any update.

AT&T S20+ 5G not receiving updates

Hi Community,
I bought my S20+ 5G in October and since then it has not received any updates, neither security patches nor Android 11. I called AT&T and Samsung both but they kept putting the blame on each other. By searching online I realized this seems like a theme in these kind of issues. The only option I feel I have at this point is to install the upgrade myself. I'm more concerned with Android 11 than security patches. I still got for security patch from June 2020 and One UI 2.1.
With this context can you please help with the below questions:
1. When I try to look up the firmware using Model:SM-G986U and CSC:ATT in Frija or SamMobile nothing comes up. I'm looking for G986USQU1CTKH. Am I missing something?
2. But it does come up with CSC:TMB. Can I install this version on ATT branded phone?
2a. Is the TMB version exactly same as ATT version?
3. Does this process trip the Knox counter?
4. Does this process void the warranty?
5. Are missing software updates covered under manufacturer warranty?

AT&T doesn't allow their firmware to be publicly available for any of their devices. Have you attempted updating your device with Smartswitch? Flashing T-mobile's firmware isn't an option to receive updates on your device. This post has information and answers to your questions.
G986U and G986U1 Firmware Links and Flashing Discussion Here
For those who aren't already aware, G986U is the model number of all of the US carrier versions of the S20+. The G986U1 is the model number of the same device, but sold by Samsung SIM unlocked and with no carrier bloatware. Firmware is 100%...

Question How does one manually install the SM-F926NU/U1 OneUI 4.0 OFFICIAL RELEASE?

How does one manually install the SM-F926NU/U1 OneUI 4.0 OFFICIAL RELEASE?
I have flashed the U1 software on to my AT&T SM-F926U phone so it is not U1. I was curious is it possible to flash the Korean official release? Is that the only one that's been released so far? Also, as far as unlocking the bootoader once your on ONEUI 4.0 does OEM unlock appear on the phone as I seen the cameras no longer die....?
The official rollout has been halted due to serious issues with the release (there are plenty of posts and news stories you can find on searching). So, right now, the answer would be no, unless you really MUST have it and can find it, I would wait.
As for the camera's still being locked when the bootloader is unlocked, no firm answer as of yet as there have been conflicting reports.

I have the Canadian W series with the U1 software installed. I tried installing the KOO series UKO (latest 7 December) with modified ODIN (abl(1) error; probably some sort of bootloader check error). So, no OEM/bootloader unlock for the US/Canada (blocking that has to be a violation of some law somewhere or maybe soon).

KOREAN is N series; US is U (carrier) and U1 (unlocked) while Canadian is W (Canada does not have carrier locked phones)

You can NOT install the Korean build to the US models. And the official 4.0 has not been released to the US yet.

samsung is redoing the beta for now
and also they restarted doing the one ui 4 update to as form what i gotton
First, it's a good idea to read the threads already posted. Your question has already been addressed in a few of them. I've even posted about Sammy postponing the rollout due to several issues found in A12 in 1 or 2.
Second, in doing so, you'd see that regional models have different alpha codes on the end of the model number. The Korean model is NOT the same as the US, just like the Chinese isn't, etc.
Third, there is a thread that shares the process of using Odin to install the betas for A12. If you WANT to attempt it, please read that thread very thoroughly. Seeing that you've been a member since 2012, I'm sure you already know this.
Updates are rollin in I guess and we will get it for sure.
Thread closed due to redundancy. Please continue with your discussion here.

Unlocking a S20 from EBAY locked to SPRINT?

Unlocking a S20 from EBAY locked to SPRINT? Haven't bought it yet, just acquiring how hard/extra cost.
I tried to look this up in this forum. Couldn't understand it. Not sure, but apparently can flash a ROM to a different carrier's rom? and that you need to buy a service (forum member) bootloader unlock? So many abbreviations and terms...
Canada, if it makes a difference.
