Update OP3 from 3.1.2 to OOS 5.0.1 (process and files required)

Hi guys, I have a OP3 which is running on 3.1.2 Marshmallow.
I always get a notification for system update to 4.5.1. I've tried downloading and installing the update but after the first boot my OP crashes/gets bricked. There is only a Linux penguin logo that appears no matter what button you press.
From there I always have to follow the mega unbrick guide and get my phone back to working with stock recovery and 3.1.2.
I've tried side loading the downloaded file as well.
Then I've tried installing .zip file of 5.0.1 via TWRP, still no luck. it still bricks my phone.
Am comfortable rooting my phone, my bootloader is unlocked. I don't care too much about keeping root after updating my phone to the latest version, I would be grateful to anyone who can point me towards the proper full ROM files of 5.0.1 along with any firmware files that may be required.
And the exact process of when to flash the firmware and with/without which version of TWRP. I am ready to completely wipe and clear data.
in simple words I just want to update from 3.1.2 to 5.0.1. The simple downloading and updateing from the OTA update doesn't work.

I read something about wrong batteries causing this problem. Do you use the original battery?

I though of running a diagnosis check by dialing *#808# and looked up Charger option, it shows the battery as "itech_3000mah"
is that original?
I had given the phone to repair for water damage to a professional service chain (Not OnePlus, some company here called Yaantra). I've heard from talking to an official repair person of OnePlus that fake batteries are not possible for OnePlus.
The battery works absolutely alright, charges up nicely and I get decent SOT. Can't complain at all.

Note 8 T-Mob downgrade after update to Pie Beta

Hey All, any chance of getting a step by step to downgrade back to CRK1 or latest Oreo build. I attempted to do so, using the firmware from SamMobile, and it failed during the "Updating System" step with an "Error!" message at 32%. Odin had registered a pass. I installed the Ap, Bl, Cp, and the clean CSC. There was only 30ish percent of battery remaining if that would make a difference. I also had the December update installed when I updated to the DLR6 version.

logs from odin? Or any error code or anything?

Nothing from Odin at all. Odin registered it as a Pass. And I'm unsure how I would pull logs from the phone. Once the "Error!" appears during update, the phone will enter a bootloop unless I hold down the power button to enter Recovery. I was able to successfully enter Recovery, reinstall the Pie Beta Update from my SD card, and the phone works fine again. However, I do use Samsung Pay, and I've noticed that service has suffered considerably, so I'd like to go back to Oreo for the moment.

Which ODIN are you using? Make sure you're using the modded 3.13.1. Try this: Uncheck the auto-reboot option on ODIN. Flash the Oreo firmware and let it finish. Once it's done, manually reboot into recovery and perform a factory reset. Then boot into the OS.

That only happens when they update the bootloader version. It has nothing to do with the OS version. The Pie leaks are still on the v5 bootloader.

Ok, I will give that a try. I will admit, I'm really enjoying Pie, and its user interface tweaks. I just may forego Samsung Pay and wait until Pie is out of Beta.
On that note, is there any way to install the old radio and use the Oreo radio rather than the one bundled with Pie, assuming that Pie has a new radio bundled. Because that is kinda the Beta killer.
And last comment, once Pie is out of Beta, what will I have to do to upgrade to the "Release" version. Will it be an Odin install, or should an OTA take care of it?

Also check the USB port, use the older USB port this has happened to me or PC and see the phone is probably not compatible with newest USB port....

What issues are you having with Spay? It seems to work for everyone else, me included.
No, you can't flash a different radio.
Not sure yet what will be required when when the official drops. Won't know until it drops.

So the Pay app opens fine, and it authenticates the card without issue. It will also allow me to put my fingerprint in, and then have the countdown start. However, it doesn't seem to enable the mag spoofer or the nfc chip, and when put next to a mag reader or Pay system, nothing happens. The countdown will continue, and will restart if I ask it to. But again, the phone doesnt seem to do anything.

Weird. I'll have to try it. I thought it was working, but now I'm not sure. I use my Gear S3 so often to pay, now I'm not sure LOL.

Update on the effort to revert back to CRK1.
Used the modified Odin, and un-checked auto-reboot. Phone remained in Download mode.
I could not figure out a way to go from Download mode to recovery mode directly. If someone knows how to do this, it would be appreciated if you could let me know.
However, rather than the "Error!" message, I received a "Erasing" message. Than the phone rebooted, and just kept rebooting, going from T-Mobile splash screen to Samsung and back over and over, with some optimizing apps screens thrown in for good measure.
So I tried again with auto-reboot on, and this time received the "Error!" message, and was able to go into recovery once that happened.
The odd thing is, nothing on my phone was changed, other than having to redo the Samsung biometrics for security. All of my apps and accounts and emails were already there, undeleted.

One more update on the S-Pay. After reinstalling the Update.zip from my SD card in Recovery, iIt does seem like there may have been a change. It is now doing the vibrate thing, which I don't think it was doing before. I will put it to the test later this week.

Yes! I'm sorry I thought I told you to try a factory reset. You have to factory reset when downgrading. Otherwise bootloop city. Sorry I wasn't more clear, I could've saved you some frustration.

No worries, and I did very much appreciate the help. I should have realized that that should come first. I was a bit frustrated and wasn't thinking logically. It was actually the "fixing apps" message you get when you upgrade that clued me in I wasn't properly resetting the phone prior to install.
Regardless, its all good, and now that I know how to do it, I'll be more inclined to try these out in the future.

Any specific reason for the downgrade? Anything not working?

Root galaxy S10 (July security patch update)

hi to all, has anyone managed to root on galaxy s10 with the July security patch update? I tried the same method with magisk but there is nothing to do, every time it gives me a different error. In the last attempt I made during the boot phase, in the upper left corner, it was written: "only official released binaries are allowed to be flashed" or something like that.

You didnt do it right. I would suggest youtube the magisk rooting process

Same tried to root it
I, was able to get it to root but the camera still makes my device rebooted
And tried to do it with ap file by changing recovery inside to the patched twrp that didn't work just booted into stock recovery instead

TWRP ≠ Root.
With the latest patch the camera crashes if TWRP is flashed. With stock recovery everything should work fine.
I'm on Exynos ASG8 without any issues, except slow wifi in apps (not browser).

It is...nearly everytime Samsung throws out a new security patch TWRP is crashing the camera.
This is what I found out after having the same issue. I don't know if there's a new version for the latest patch.
Aren't the custom roms based on One UI? Shouldn't the stock recovery still work? (I really don't know)

TWRP is good to have if something goes wrong.
I can have custom rom without twrp but that's not the whole of it.

It's easy to flash it, even without running system.

Hi everyone, I'm still ASD4 and basically haven't update since because everything is a hassle these days. Now I thought maybe it's time to update, but keep reading things like this and camera, wifi bootloops problems etc.
Are these issues a real thing? or just some individual cases where it happens?

It's real like a $2 dollar bill.

I'm always afraid that I install something or make a small change and end up in a bootloop... I wish twrp and everythign work just fine like before and I could make a backup after installing a rom and doing the most basic stuff.

Since this is the first post that comes on Google for "only official released binaries" "s10".
I had this problem again and again, and it seems that it was caused by one of the reboot not being done with the correct timing with the 3 buttons.
The thing I was missing was after flashing the patched AP files (and the other files).
When you restart, keep the 3 buttons pressed until you see the blue screen and then release only power (keep vol up + bixby) to get into reset mode.
I think I didn't keep them pressed long enough.
If the device restarts, keep pressing the 3 buttons (never let it restart without pressing them).
Once the factory wipe has been done: Restart with the 3 buttons, and keep them pressed until 1 to 2 sec after the screen that asks you to press the power button to continue.

[samsung note 8][revert to stock firmware from custom]

Alirghty so i bought a used samsung note 8 duos. it says it on the back, in the software, in smart switch, heck even the AP and CSC files are infact for a SM-N950F
Here is where the problem is as far as I've figured out, I'll explain what the firmware files are on the device taken from dialing *#12580*369#:
BL:N950NKSU5DSK1
AP:N950FXXS7DSH1
CP:N950NKOU5DSH1
CSC:N950FOXM7DSG1
The phone runs fine honestly but its bugs me that there two different binaries mixed in my phone from what i can tell the BL and CP are from a Korean level 5 Binary (also can someone tell me why security levels matter now?) and the AP and CSC are from F model level 7 Binary
I cant flash anything stock cause its the only thing ive tried and it just wont let me. I am downloading a level 5 binary in *hopes* that it doesnt see an issue with the security levels between firmwares as i always get the fricken PIT error or secure download error orrrr the magic string invaild
All i need is a way to get my dualsims back up and running ive got two imeis on this phone which ive checked online and theyre working also id love it if i could just get all 4 files to be from the same firmware zip
FYI the only thing ive been able to flash is TWRP after which i got to installing no-verity and magisk, Ive been using twrp backups as a failsafe to revert back to the 'original' state my phone was in and thats the only thing working for me so far and i may or may not be a noob in flashing samsung devices

The reason for that is because the phone has obviously been repaired using different hardware from different devices. It's never going to be able to flash normal firmware being that there's different hardware in it. If you want to upgrade that you'll need to use the different versions of firmware for each different hardware.. I'd just send it back if I bought it from somewhere like that.

Revert to Stock
I owns one Galaxy Note 8 SN950-F Indian version,
I have installed one custom ROM for my mobile last month and now i need to revert back to stock.
How can i do it ? Once i installed stock OS using Odin but Knox looks crashed and apps like secure folder not working !
Can i get it done through service center ? When i contacted them they said its impossible as you have rooted once.

Once Knox is tripped it takes a motherboard replacement to revert it.
If SF (Secure Folder) is that important to you, stay on a custom rom that has patched SF patched already.
Literally all TWRP/Rom threads warn you of this, always read the whole OP of any thread in the future.

Yeah. Thats what im doing now. Running on doctor ketans rom.
but im little worried now. Because haven't used any custom roms and worried about security issues.
Can we still go back to stock os ? With genuine updates?

Like I said to you above, once Knox is tripped SF won't work, if SF is that important to you stay on a custom rom that has patched SF. If you're worried about security updates use DeluxeRom which has last months security patch.

Good source for firmwares?

I'm looking for a good source of firmwares, i know the famous sites but some firmwares doesn't seem to be listed. I know in the time os Samsung KIES there were tools which communicated directly with samsung.
For example these firmware builds for the SM-G975Ux aren't listed on most firmware sites but have the December secutiry update with binary/bootloader version 8: G975USQS8IVL1 and G975USQS8IVL2

All the big sites have ROMs for that phone (same one I have). There is no "Ux" model... it's *U or *U1, with the latter being unlocked. IF you search for U1 ROMs you have many selections, but most get the XAA version which will usually change carriers automatically based on the SIM card.
The latest BL=8 version I see there is https://www.sammobile.com/samsung/g...M-G975U1/XAA/download/G975U1UEU8IWB6/1741280/ which is the February 2023 security update. I believe this is the last one we are getting (but I could be mistaken as there may be 1 more security patch, I don't remember).

There's U U1 0 W F N .... I'm looking for the oldest firmware with binary version 8, but it seems the sites don't show all firmwares available.... i'm looking for the oldest firmware with U8 bootloader (or any compatible bootloader with binary 8 version), i could have a look at all sites and try my luck... but they don't seem to have all data. but like i said i prefer some original source xml files... i saw some url's to original samsung servers but can't find them anymore.
There is already a firmware available with the march update.... but you have to be lucky to find them... i'm looking for original sources. like update.zip's and such
Found the first one....
https://fota-cloud-dn.ospserver.net/firmware/TMB/SM-G975U/version.xml

I'd recommend around sammobile and samfw. These are the two sources I use the most

hey!

after I wanted to update my g973f from "G973FXXUGHVK1" to "G973FXXSGHWC2" (I tried odin 3.13 and odin 3.14) and an error occurred, I can't install anything anymore... recovery and download mode work, and I can also flash the original firmware, but the device no longer boots into the system! even custom roms don't want to boot anymore
Can anybody help me further?

Do you mind explaining a bit more? Do you mean like that it boots you into recovery only or?

if i flash a new rom (whether original or custom rom) nothing happens after the reboot... download mode works too, flashing twrp works too! however, the system boot does not work via twrp either... not even a bootloop, the cell phone does not react at all! the task combination for

Right now I don't even care if I get the original firmware or a custom rom running... I hope I didn't brick it (((

My old device was a G930F, its unbreakable make sure you flash the right rom and wipe data and dalvik cache after flashing.... THis ons is locked so it doesn't have fastboot. My G-930F came with fastboot enabled so you can always fastboot a recovery.img. like TWRP
Did you try to download TWRP from twrp.me and "fastboot boot twrp-3.7.0_9-0-herolte.img" ? it should boot to twrp in fastboot mode (hold volume down + home + power).

1. is your KG status is broken?
2. Is your bootloader unlocked?

You know how to flash lineageos through twrp right? and how to use odin?
Maybe flash lineageos to see if everything works.... and then revert to original software. Be sure to wipe cache/dalvik and userdata

There's U U1 0 W F N .... I'm looking for the oldest firmware with binary version 8, but it seems the sites don't show all firmwares available.... i'm looking for the oldest firmware with U8 bootloader (or any compatible bootloader with binary 8 version), i could have a look at all sites and try my luck... but they don't seem to have all data. but like i said i prefer some original source xml files... i saw some url's to original samsung servers but can't find them anymore.
There is already a firmware available with the march update.... but you have to be lucky to find them... i'm looking for original sources. like update.zip's and such
Found the first one....

Yes, I know there are many other variant firmwares out there, but for a U phone (snapdragon) there is really only U and U1... the rest are incompatible.
There is no "older" firmware with binary 8, because the firmwares are packaged with the proper/compatible binary already. Basically, the "binary" is the bootloader version. On Snapdragon phones, you must have the proper BL/binary to flash, as you already know. You can't interchange the binary/BL with the ROM and security updates because they are not made that way.
The update.zip you're looking for are updates sent by Samsung directly, and they can update the ROM (and Binary) from one stock version to another... but, again, they will update both the binary/BL as well as the ROM, so they can't be broken up to only do one or the other.
It sounds like you're trying to get to an older ROM version (for whatever reason) with an older security patch level as well? Basically, this cannot be done on Snapdragon phones. Once you're on an updated binary/BL, you're stuck there (at least today you are).

I solved the problem! I had unlocked the bootloader, but I also had to deactivate verity via CMD with twrp+adb "adb disable-verity"
ok i've solved the problem now, but does anyone know why i couldn't even start the original stock roms? Actually, the stock ROM should set everything to factory settings...

Thank you for helping so quickly with ideas... I would not have expected such quick help with such an old model, even samsung customer service didn't want to help me yesterday

I've tried different firmwares, its all about snapdragon. You can also flash SM-G975W parts and other snapdragon variants.... there's a lot of variants out there.
I first upgraded and then downgraded to the parts i wanted and am on a rom now with security patch level December 2022, as long as the binary version is the same there's no problem. I've got the latest modem installed and the oldest firmare and bootloader for the latest binary version, i can upgrade or downgrade my bootloader. I already asked someone before if this was possible and if he could confirm because before i was only able to flash CSC and AP i think.
If there's no updates comming anymore why not downgrade and wait for a new leak
I'm also sure we can unlock the bootloader, i'm trying to make an lposed module. I've installed lspatch and lposed and they work fine for some modules. The bootloader unlock has several prerequisites (properties and such) if i can make it look for other properties or something like that we might get an unlock option. Also it looks for an encrypted file on EFS, if someone with an unlocked samsung phone could copy that file we would be a lot further.
It's called /efs/sec_efs/sktdm_mem/encmembership.txt and should be an encrypted file, also if anyone knows how to set ro properties without root (like a stub before the preference controller starts) this would be very usefull.
