Galaxy s20+ how to downgrade from Android 11 to 10
A few apps do not work because they cannot access Android\data folder , but especially i have a Map Navigation software that i need to copy/paste/modify files in Android\data folder ... plus i hate not having full control over my system
1- I tried Frija but it gives me the "latest" firmware of Android 11
2- SmartSwitch does not show the downgrade option ( probably because i never created a backup with it while on 10 )
3-Googling i cannot seem to find the Android 10 firmware for CSC=G986U1OYM1CTKJ ;; PDA=G986U1UEU1CTKJ ;; Frija full version = G986U1UEU1CTKJ/G986U1OYZ1CTKJ/G986U1UEU1CTKJ
Thoughts ?

I did ... but for version 10 ... the PDA and CSC do not match at all - THOUGHTS?

DOH, I should have posted the G986U1 link, change it at the top and choose your country/carrier, they look correct.

.
.
I apologize ... but shouldn't the PDA and CSC match ?
.
Plus i have Visible ( kinda works on Verizon ) ... and there are 2 Android 10 Verizon builds
.
Usually i tried to match the versions exactly

Not always. I suspect the generic releases match but if the carrier has updates for their network they might be different.
On my S20 AU/TEL list most of them are the same but there are a few that are different. Since I had been doing OTA updates I just relied on what was being sent for my carrier, and I downloaded the July & August firmwares from my list.

[NEWS][+DOWN.LINK] Galaxy A8 (2018) and A8+ (2018) Oreo update rolling out in Russia

According to Sammmobile.com , Samsung has finally released the Galaxy A8 (2018) Oreo update, bringing an end to months of waiting for owners of the company’s latest premium mid-range phones. The Galaxy A8 (2018) and Galaxy A8+ (2018) are currently being updated to Android 8.0 Oreo in Russia. The rollout seems to have started over the weekend, and since it’s already mentioned on Samsung’s official website that details software updates, it should be available for most (if not all) users in Russia at this point.
Samsung’s official changelog suggests it’s an update similar to the one received by devices released before the Galaxy S9. Oddly, Dolby Atmos support isn’t mentioned, despite the devices’ user manual saying it’s included. That could possibly be because the A8 and A8+ only get Dolby Atmos for use over wired and Bluetooth audio, similar to devices like the Galaxy J6 and the Galaxy A6. The update also brings support for VoLTE on both SIM slots, which was recently made available for the Galaxy S9 as well. It’s unclear what security patch is included, but since the May security patch has already been out for these devices, it’s possible Oreo bundles the June patch. The July 2018 security patch is included in the update. The build numbers are A530FXXU2BRG1 and A730FXXU2BRG1.
Our What’s New With Android 8.0 Oreo series of articles is the best way to get details on some of the major new features and changes that Oreo brings to Samsung devices (and this official Samsung infographic is also something you should take a look at). To see if Oreo is available for your Galaxy A8 (2018) or A8+ (2018), open the Settings app on your device, tap Software update, then tap Download updates manually. The update is likely to take a few days to start rolling out in other markets; it could also be a few weeks, depending on how quickly Samsung expands the rollout.
The Russian Firmware is avaliable on Sammobile.com on the link below :
https://www.sammobile.com/firmwares/galaxy-a8-plus/SM-A730F/SER/download/A730FXXU2BRG1/224366/
My question is ... will this firmware work on non Russian devices ?
It will.

How to get update my 8GB V20 ?

Hello,
I'm a new user of Honor View 20 8Gb RAM and 256GB stockage).
Actually it has the following firmware: Build Number 9.0.1.139 (C432E1R2P1)
Model: PCT-L29
As I see on some links, there is new updates but I can't get them from my mobile. Has anyone updated his mobile manually ?
Can I force the update from my mobile ?
Thanks in advance.
Regards.
That's interesting cause I have the same model and I'm stuck at 9.0.1.137.

It depends on region. Even though the latest version from Huawei's servers for PCT-L29 is 9.0.1.140, in the UK the servers will only allow you to go up to 9.0.1.137.

Unlocking the bootloader

I haven't really done much advanced stuff with android for a while and wanted to hop back in, but I cannot find the oem unlock option. I've tried doing the date and time thing, but that didn't work. Is there a new bootloader? I remember it always being just blue with no options, but the one I'm seeing is different.
*A little description of what it looks like when I boot into the bootloader just to make sure I'm not crazy: It has some info listed: (in red) FastBoot Mode, Product name- kona, Variant - SM8 UFS, Bootloader Version - , Baseband Version - , Serial Number - ***********, Secure Boot - yes, (in red) Device state - locked.
Pushing the volume buttons scrolls through 6 options, Start, Restart Bootloader, Recovery mode, Power off, Boot to FFBM, And boot to QMMI. The last 2 options and Start just boot it into recovery mode, I'm assuming I need the device unlocked to use these?
What device do you have? Is it Snapdragon United States? If so there will not be an oem unlock. You have to unlock through paid service and that depends on what device and what bootloader version your firmware is on.

Ive found out a little more, looked into Sampwnd and they weren't able to do it. I have the g988u and version 2 of the bootloader it seems. Is there another payed service that I can use for my phone and software? I have only been able to find Sampwnd.
Only bootloader 1 can be unlocked at this time. And you can't flash back once bootloader upgrades.

That's too bad. Thanks for the help. Will the bootloader ever be able to be unlocked? Or is it just not possible?
They are working on certain devices with later bootloader.

What version oneui? 3.0 and below can be unlocked I believe. I'm no pro but this guy is @afaneh92. If it can be done, he can make it happen. Reach out to him, he's super helpful. He just helped me unlock my S20 a couple days ago. Smooth as butter.

Unfortunately I have version 3.1, from what I understand they have updated the bootloader and previous methods don't work with the new one.

Bummer. Pretty sure you're correct. SOL until some smart individual figures out how to get around it.
I've got an S10 which is a version 6. The magic number is 5. Going to sell it while I can.
I'm looking into getting a S20 Plus and was told has to have B1 to be unlocked. I'm coming from a dead Galaxy S5 I have no phone at the moment. I just want a reliable devices that I can make received calls, texts and doesn't have camera issues (like the Ultra) and can be rooted. My S5 died it was having hardware problems and went into complete mobo failure cant restore or boot any roms anymore period. And I hope @afaneh92 can unlock if it has a B2. I'm looking at buying brand new from either Swappa or https://fusionelectronix.com/samsung-galaxy-s20-plus-5g-sm-g986u1-128gb-factory-unlocked/
I'm on Verizon hopefully unlocked phones will work on network? I may switch to T-mobile or another provider!
Hi, I am Android 11 and I opened my bootloader a few days ago, it is a very simple task

For s20 family, Bit1 is all that can be BL unlocked at present. Nobody has info on when (or even if) a Bit2 unlock will be available.
You can still find Bit1 s20 series in excellent condition on ebay, it just takes a bit of time. Clearly ask sellers what the last 5 characters are under Settings - About Phone - Software Information - Baseband Version.
I'm BL unlocked, rooted, running Bit1_Safe AP/CSC (the 2DUH2 Build Number).

Right.... I thought the only ones that had Bit1 have Android 10 according to this site? https://www.sammobile.com/samsung/galaxy-s20-plus/firmware/SM-G986U1/VZW/#SM-G986U1
Sooo say I get a S20+ from the follwoing site brand new how do I know if it has Bit1??? https://fusionelectronix.com/samsung-galaxy-s20-plus-5g-sm-g986u1-128gb-factory-unlocked/
And can these phones be be updated to Android 11, 12 etc....? What about any security updates?
Your camera does not have any focus issues and you dont get the "camera failed" error? Many Galaxy's had it including my S5. I'm sure this phone is a big improvement from it! I didnt like it didnt have OIS so pictures came out a bit blurry sometimes.

Ask any seller what firmware is on the phone. If it's a brand new, shrink wrapped, box, in some cases the firmware version is listed on a box label.
I went the ebay route, paid $432 including tax for a like new G986U. It took time, but I ended up with exactly what I wanted. For an ebay buy, recommend checking that the Sim and microSD readers work okay (Samsung has had some infant failure issues).
For any unlockable phone, I recommend that as soon as you have gone through setup you switch to airplane mode, disable Ota in developer options and run the 5 ADB commands to disable updater apps. Vzw can try to push a firmware update pretty quickly.

Wow your not rooted or unlocked BL? Well I mainly root so I can use TB to restore and backup my apps, call and text logs and install unknown apps.
I wouldn't trust Ebay again. I bought my S5 (after a short time with Developer Edition) on Ebay and it may have had previous damage. The motherboard logic board failed completely finally. Previous to this Ebay phone I had an old flip phone from like 2008 off Ebay. Brought it to Verizon to fix and it fried their system and they gave me a free phone .... found out it had water damage! @blackhawk suggested I buy from fusionelectronix.com (claim new phone) and I was looking into Swappa (mint like new used). I will have to run the firmware numbers by XDA before purchase but I need phone ASAP as my S5 is out.
Oh right and I use JODIN on Mac (same as ODIN) will it work with the newer Galaxies? I was able to flash pit / zip files no problem on S5 previously.
I am unlocked and rooted.
I use ODIN V3.14.1_modded on Windows to flash my s20+, no idea if JODIN works on newer Samsung phones.
It's completely understandable about being gunshy with eBay. If the retailer you posted allows easy returns, no reason not to try them if you wish.

How do I get the PIT file and firmware file for S20+ SM-986UI? I will need it for JODIN. I'm reading online and research shows I can use something called Samloader?
If I must use windows to use ODIN I can try to find a copy of it and setup in Virtual Box like I did previous to JODIN.
If there is a warranty on the new phone can it be returned to stock?
I emailed the company i'm interested in buying from so waiting to hear back.

General Samsung galaxy Fold 4 getting stable Android 13/ One UI 5 update in India

This one seems to be only for Beta testers as it is just around 300 MB . They should be pushing a stable build for non beta testers soon .
In EU (netherlands/germany) they say november full srable version will come. I also will sideload (and root) the rom trough Odin.
A later build, BVK5, is now rolling out to all users in South Korea on their Fold4, F936N, and Flip4, F721N, devices.
See... https://www.gsmarena.com/samsung_ga...able_one_ui_50_with_android_13-news-56567.php
What is the difference between SM-F936N (Korea) and SM-F936B version. When I had note 20 ultra, there was one version and I could flash KOO CSC files on my Indian note ultra.
In this case I don't think I can do that.

You can download it, using SamFirm or Frija, model SM-F936B, CSC INS, which is part of OXM multi-CSC. This includes all of Europe, I think most of Asia. Full Firmware, official, signed.
Flashed it on an EUX or EUY Fold 4 using ODIN without problems, as it is part of the same multi-CSC OXM. Remember to use HOME_CSC for CSC file to keep your data.

can't flash with odin even though bootloader being unlocked

i've got an a50 that i want to install TWRP on so i won't have to use the abomination that download mode is. i've unlocked bootloader, yet when i try to flash the TWRP .tar in odin it fails and the phone gives the following error code: "Only officially released binaries are allowed to be flashed(RECOVERY)"
although this is the first time i try flashing stuff on a samsung so you can consider me a newbie, i've got experience with fastboot on others so it must be something i glanced over.
cuz see, when i unlock the bootloader of other phones they let me flash onto them, unlike this one. if you could redirect me to a post with a solution or something that would be very much appreciated!
If you are on the latest official build, then The latest official build (last official Update from samsung) won't allow the twrp to be installed.
Use previous build to install twrp.

You can proceed.
The problems you may get with FOD, VoLTE. Some operators like Jio completely depend on volte . Without volte we can not make calls and receive messages. Only internet Anwould work.
No aosp rom able to make work volte. For now, volte works only on oneui roms for a50.

so if i'm reading this correctly, the device won't be able to make calls if i don't use oneui?
