Just bought S6 G920T so i'm still new to all the bootloader security issues, i flashed TWRP yesterday and got stuck on bootloop after that. Bootloop was fixed after flashing Twisted v4 rom. I set up everything including fingerprint and when i restarted the phone it gave the error "Custom Binary blocked by FRP".
Currently i am trying to revive the phone, about to flash 6.0.1 PK5 firmware.
Now i have a few questions, please answer whichever you can:
- In case flashing 6.0.1 fails the next solution is to flash 7.0 firmware, is it possible to flash Twisted v4 (6.0.1) after that? Or i have to go with Nougat roms only?
- What should i know to avoid ever having another FRP lock again with a custom rom? Dont set up fingerprint? Or enable OEM unlock option is enough?
- Any way to permanently disable this Custom Binary lock security feature?
I want to use Twisted v4 with root and fingerprint if possible (dont need Samsung Pay). Sorry if this is a repost, i tried gathering whatever info i could on this issue but still confused on these questions. Thanks in advance! :highfive:
EDIT: Looks like this forum is dead, so i'll just answer my own questions from what i learned today with first hand experience for the next confused soul.
- Flashing 6.0.1 PK5 firmware fixed the FRP lock issue (if you were on newer firmware you will need to flash that one or higher)
- Enable Developer Options by clicking Build Number a few times, in Developer Options allow OEM unlock to avoid "Custom Binary FRP lock"
Now i am using Twisted v4 with root and fingerprint enabled, TWRP is installed and no issues till now.
If root/TWRP is what you're after, is the Tmobile version the friendliest S6 to get?

Yes. The TMobile Galaxy S6 is the last Galaxy model with an unlocked bootloader.

Its ok bro, experience is the best teacher
don’t mean to hijack, but
Saw this now after I posted and you’re saying it’s dead (which sucks, but oh well)
Which version were you on before flashing entirely?
Any chance you could lemme know what to google to grab the 6.01 fw? I’ll try that out I guess.
I’m having frp lock and can’t even flash anything it seems, but I’ll try anything.

You can download the PK5 Firmware here > https://www.sammobile.com/firmwares/galaxy-s6/SM-G920T/TMB/confirm/G920TUVU5EPK5/113173/
OR...you can try to use Samsung Kies or Samsung Smartswitch to restore your phone back to stock. You'll need the model and serial number which you can get by booting to Download mode and then pressing the home button. Once you get back up and running on stock firmware you can enable developer options then USB debugging and OEM unlock.
Once you have those taken care of you can root, install TWRP, Xposed, and flash Twisted Nougat.
hate to be annoying, but is there a better place to find this rather than a place that will take 12 hours to dl?

Like I said u can try using Kies or Smartswitch. I have used Kies successfully on a handful of S6s without issue. Otherwise I could probably download it tomorrow at work and send you a link.

No worries. I’ll do it overnight. Thanks
Also Odin 3.10.6 started being able to flash where 3.12.? Failed.
I got the baseband you have in your sig I just installed. Still have FRP tho and was told to wait 72 hours.
Mean time my fiancé just bought an iPhone instead.

Been away from xda for a while so didnt see your post. Instead of sammobile you can usuallly find firmware on androidfilehost. If you were on 6.0.1 before then you should be able to flash this file:
https://androidfilehost.com/?fid=745425885120707260
if that doesnt work then 7.0 file should work (basically you need the same version that was flashed or updated version, older versions not allowed):
https://androidfilehost.com/?fid=961840155545571517
ONLY FOR Qualcomm SM-G9650
Team Win Recovery Project 3.x, or twrp3 for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.
This will trip knox to 0x1, your phones warranty will be voided, flash at your own risk. Also, this process will wipe your personal data!
HOW TO INSTALL:
0. Make sure you enabled developer settings by pressing the build number several times and have the OEM unlock enabled. Also make sure you run CROM from the galaxy apps store to unlock the bootloader.
1. Boot into download mode by pressing: bixby, volume down and power
2. Download the latest Odin version, open it
3. Download the recovery file from below and put it into the AP tab
4. Untick "auto reboot" in odin and flash the file
5. After flashing, boot into twrp. Make sure to NOT allow system to be modified till you disable dm-verity! (otherwise your phone will be stuck at bootloop).
6. In order to fully and properly root, you will need to flash my kernel found here and flash Magisk.
7. To disable encryption you need to flash this RMM_patch+forceencrypt_remover.zip for pie or multidisabler.zip and forceencrypt_disabler_q.zip for Android 10 and format data. (can opt out of the forceencrypt_disabler if you want but internal storage will be inaccessable)

I saw that and seriously thank you so much!! There will be a Qualcomm section opening soon for Snapdragon variants. I have SM-9600 already in there for TWRP. I need to update it I know. I will get to it this week. I also need to get the devices officially supported and forked over to TEAMWIN that will get done too when I can get the time.

Buddy I meant, were you able to disable the CROM lock after removing the Samsung Account. Without getting the device unlocked by CROM service app you wouldn't be able to flash custom binaries.
Thanks

Edit: I think I have the answer...
I can't find the CROM Service in the Galaxy App Store on my firmware (ZTO, Brazil). Even tho I'm OEM unlocked and I installed the CROM Service apk, I still have that issue, so the main question here is:
On what Galaxy App Store the CROM Service is available to download? I believe that if I install that firmware and download the CROM Service directly from the original Galaxy App Store, the program will succesfully unlock my phone.
Can anyone please help me with that question???
Best regards!

Hi Kimbaroth,

CROM give me an error.
Dev Options > OEM unlock (restarted and factory reseted the phone after that).
Now I need to wait one week?

I believe your device is already OEM unlocked, the only difference is that when the option pops again, it will show the option as unlocked.
We need a fix for the CROM Service unlocker, I really need to fix this issue. If you find something, please let us know.

I'm in the same boat, OEM Unlocked, but CROM does not work, it just fails. I do not know if we have to wait until we see the "OEM Unlock" in developer's options and them we can run CROM.

If you check my post above, you can confirm that "that" doesn't affect the CROM Service at all: https://www.dropbox.com/s/ts78hdnp4j9jffu/1OEMUNLOCK.jpg?dl=0
As I stated, I believe that the CROM Service only work if you download it directly from the Samsung App Store (and not just install the APK that is posted here).
The CROM Service app is not listed at least in my App Store (As I said, I'm currently using the ZTO firmware), so maaaaaaaybe if we flash another region firmware, it will work! The real question is... what firmware do we install??? CHC??? (Open China).
Please help ussssssssss!!!

So, flashing a chinese firmware will not fix it, right? D=
Salutations everybody. I haven't had a phone from sammy in a while. Finally invested in a SM-N950F note 8. It's oreo. Tried to root earlier today using the pinned guide in the Guides forum. After going through the process, and flashing twrp. Then formatting data. And rebooting it to twrp (which I did a couple of times) (May been where I messed up,but it doesn't seem likely to me) I flashed the oreo n950f oem issue zip and rooted with magisk. Upon rebooting & enabling dev options. The oem toggle was missing. The guide didn't say what to do in the event that it was missing. Just that it was safe to reboot if it was there, and enabled.
Me being rushed for time rebooted anyway, and now when I try to boot up I get only official released binaries may be flashed, and the phone shuts off.
I'm aware I can restore to stock via odin. But I have a couple of questions.
A. Can I use the same odin version I used for the root process to return to stock, or do I need a different one?
And
B. There are loads of options for country and carrier on sammobiles site. I bought the phone used and have no idea of its country of origin. There is a version that says unknown for country and (bat) for carrier. Is that one safe to use, and is there any difference between the firmwares other than carrier setting being preinstalled (would be my guess of the only difference.)
Thanks in advance for any help you can provide.
This msg Only official released binaries are allowed to be flashed cause of the new security patch lock which called RMM or KG and since u were rooted before then u got this error that's cause you flashed a new BL to your device or you were connected to internet before editing kernel to prevent samsung to add the new lock to your device anyway a normal flash through odin will solve your problem and your device will be ready to use it again without any problems but also without any custom files like TWRP and Magsic which means u will not be able to root your device before editing kernel to remove the new security patch lock

Okay I was thinking I might of missed something. The patch for oem issue I thought covered that.
Is the unknown (bat) firmware the one I need to flash to stock?

Using odin 13.1.3 is recommended.
As you have the N950F, it is part of the multi OXM CSC, so you can flash the filmware for you country and carrier if desired (N950F)
If you want to root, I suggest just flashing a custom rom or kernel, as they have been patched for the RMM KG state issue.
Hello!
the latest MIUI update I've received, 13.0.17.0.SKFMIXM, is not owrking as good as the one I was using, namely 13.0.16.0.SKFMIXM.
I've found and downloaded the 3.41 GB and something full rom and the OTA update of 266.39 MB.
I've tried with each one the following procedure:
rename the file to update.zip
copy it into the root folder of the phone
tap various time on the miui 13 logo to get the "select update package menu"
...every time it says that can't verify the update package, try via usb.
I was so happy with the 10.0.16.0. what can I do? I fear that a factory restore and a subsequent update will bring it back to 13.0.16.0.
Thank you in advance for the help.

Google fastboot flash with PC or recovery flash via custom Recovery.
For both the bootloader has to be unlocked. In my opinion there's no other way to rollback .
I've downloaded the right version (EEA) and now I'm getting the message "impossible to downgrade".
ahahah. this is so stupid.
I had a nice, fully working phone, now it's back to garbage and I can't rollback. starting from the battery usage - now I can't activate the battery saver and the drop down menu is transparent and unreadable unless i turn off the battery saver.
My only option is to navigate a jungle of fake infos and obscure downloads to flash the phone - since there is no clear guide. I might be wrong; if there is a CLEAR guide on how to properly flash a Redmi Note 10 Pro, where can I find it?
Cheers.

I advise to search for the right information on XDA and the downloads from Xiaomi servers.

Downgrading using the rename trick is not possible now due to OTA validation. But still, downgrading is still possible as long as the bootloader is unlocked (you can re-lock bootloader afterwards btw so no worry about banking apps).
Procedure might be something similar to this:
1. Unlock bootloader
2. Flash any latest OSS ROM (this is just to remove MIUI)
3. Use MiFlash and fastboot method to install old versions (re-lock if you want)
Alternatively, after No.2 you can directly install the old update through custom recovery and just keep bootloader unlocked. Though this means that you'll have to deal with hiding rooting and passing safetynet.
PS: Just to add, Anti-Rollback is not yet enabled for sweet so no worries with getting bricked while downgrading. Just be careful and flash appropriately.
Thanks for the kind reply, @BigChungus321 . Glad to hear that I can still unlock and lock the bootloader! at least for those 6 months of warranty.
Just one thing, in the step you suggested you said:
1. Unlock bootloader2. Flash any latest OSS ROM (this is just to remove MIUI)3. Use MiFlash and fastboot method to install old versions (re-lock if you want)Alternatively, after No.2 you can directly install the old update through custom recovery and just keep bootloader unlocked. Though this means that you'll have to deal with hiding rooting and passing safetynet.Directly installing the old update ( MIUI 13.0.16.0.SKFEUXM ) isn't the same as using MiFlash and fastboot to install the old version, or I am missing a part here?
In this very moment I've made a backup of all the pictures and a list of all the apps installed, to help googling them again later, in preparation for asking the MIUI lords the permit to unlock my device.
Also, I've a friend who has the same phone but it has never been updated; based on my personal experience, if I'd like her to avoid the issues I've found in 13.0.17.0, would it be safe to tell her to manually update the phone with the "select update package menu"?
wow.
I was ready to unlock the phone, but I forgot to unlock the "Mi unlock" in the developer options. So I went there and seems that I cannot unlock: I keep receiving the message "connect to the netwrok and try again".
Am I missing some piece of information here?

Directly installing the old update ( MIUI 13.0.16.0.SKFEUXM ) isn't the same as using MiFlash and fastboot to install the old version, or I am missing a part here?

It is the same but I do encounter people who face anti-rollback error rejecting the downgrade if flashing from MIUI to MIUI. But going from OSS to MIUI, this arb check does not seem to occur.

In this very moment I've made a backup of all the pictures and a list of all the apps installed, to help googling them again later, in preparation for asking the MIUI lords the permit to unlock my device.
Also, I've a friend who has the same phone but it has never been updated; based on my personal experience, if I'd like her to avoid the issues I've found in 13.0.17.0, would it be safe to tell her to manually update the phone with the "select update package menu"?

No clue if that prevents the issue/bug you encounter. I usually just dirty flash the full rom update (not the incremental which is around ~200mb) in recovery and I don't seem to get issue this way, aside from recovery being replaced because dm-verity is getting activated again.

I've seen many people who have this issue too. Again, no clue how to fix this. Maybe reboot, and just enable mobile data. Try changing sim card or switching sim card slots. Use other Mi Account for unlocking. I did see discussions about how using the same sim card and same Mi account can on a different device can cause this. I still have no clue how to fix this though so sorry. Might be a good idea to use a fresh sim card and mi account if you still encounter it.
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....

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

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.
