Newest oreo beta U2ZQKM - AT&T Samsung Galaxy S8 Guides, News, & Discussion

alright here is newest beta (U2ZQKM)
https://files.fm/u/46nzxpg2
this updates your bootloader, so you cannot roll back if you do this.
You need to odin back to AGQL (only flash AP,CP and BL if you want to keep data), ota to QJC through stock recovery with this zip (https://drive.google.com/uc?id=1clYBB5bB55rxaGBQJ0SM195wXHqgiYCC&export=download) , then use this to ota again through stock recovery.
Between the odin and recovery flashes, do not go back into system. Boot from odin flash directly into stock recovery, then again from first ota back into stock recovery.
This is for tech savvy people only, and for snaodragon version only.
Thanks to @norbarb for everything she has done for this community

Can you update to this from anything else? If you're on a BL2 firmware you can't Odin back to older fw.

You need to be on QJC. It's super easy to get on qjc though. I didn't even wipe when flashing from oreo back to nougat.
There is a nougat with the other bootloader so you could flash back to that.

Okay, the latest att firmware (QJC) didn't upgrade bootloader but the unlocked firmware did. So if you're on unlocked youre screwed as you CANNOT go from bootloader 2 down to 1.

You mean the latest AQK2 OTA for XAA already upgraded the bootloader?

OTA Updates after unlock/root (Verizon)

First let me thank this community for the MANY years of great help pushing my devices to their limits. I've never register or posted because I've ALWAYS been able to find my answers with a simple search and really never have much to add.
This time I can't find a good answer. I hope this isn't too much of an amateur question.....
I purchased my Pixel via Verizon (I know....) and have unlocked the bootloader and rooted.
I really don't want to mess with custom ROM's for a while and I still want the latest stock version. How do I update to the latest version without losing recovery and root? Example: I updated to 7.1.1 the other day, then wiped, unlocked, installed recovery and rooted. I went back to 7.1 and don't know how to update to 7.1.1 again or other future versions. I hear that flashing stock rom from Google will wipe recovery and root. Is that correct?
Thanks again for all the years of sharing your experiences.

Thanks for the reply. Follow up question after scanning the toolkit description..... I'll look deeper into it in a bit.
This will retain root? Will using adb to sideload lose root?
I think so. You can just reflash SuperSU in recovery :good:

That's not possible. If you installed the 7.1.1 update you wouldn't have been able to unlock the bootloader again. So you must have had it unlocked before the update.

I updated, then decided to root so I factory reset which brought me back to 7.1...... I didn't even know it wouldn't work on 7.1.1 so I guess I was lucky to have done so. I just thought it would be safer to start with a clean slate.
It wasn't until I noticed I could no longer double tap to see notifications that I realized that was only in 7.1.1 and noticed that I couldn't update to it anymore.
Edit: Maybe when I said "wiped" I should have said "factory reset".

I realize this isn't my thread, but... I flashed factory image to my Pixel but the recovery flashing failed. How can I get stock recovery back on so I can take the update?

There's a section 'Updating instructions' in the OTA page (linked above) with instructions. Not for the faint of heart if you're unfamiliar with ADB.
It's on the toolkit options after you select your device.
Do you mean you booted into recovery and reflashed because I've actually been wondering almost exactly what you have.
I have a VZW pixel that I unlocked and rooted via adb/fastboot and I've been wonder if accepting a Verizon OTA would unroot me, and relock the bootloader. The 2nd Verizon update as we know disabled depixel and grayed out the option in dev options but do current OTA updates (not images I downloaded myself) unroot and relock which would prevent me from unlocking and getting root again

Quick question... I've been on Lineage, and have flashed this and gone back (to update the baseband). But, do you know off-hand, how do I easily root on this image? My BL is still unlocked and I've got TWRP reinstalled.
Thanks!

If you have TWRP installed, just flash a SuperSU zip (i.e. SuperSU 2.79 SR3) in recovery and you'll be rooted.
Unless of course you're talking about going back to Lineage and re-rooting. In that case, you'll have to use the Lineage root zip, which I don't have a link to.

It depends. It could be a .tar file you flash via Odin or it could be a flashable zip via TWRP. It depends on the maker of the file.
It's just the modem.bin file from the update. I don't have the time to make one for it right now.

On a side note, it seems like Verizon read the recent articles where the Galaxy S5 was still rated as the most popular smart phone being used on any network. Meaning, they are updating the phone monthly now, which is good news for us. We won't ever get Nougat but apparently we'll get Security Patches monthly now.

so can i take the modem.bin file from this update and replace it with the one from a 7.1.2 rom ? also i used to mess with porting roms but on mediatek platform , are the modem files still located in /system/etc/firmware directory?
because what i see is modem.b00-b27 ,modem.mdt

flashed the update but phone stuck on verizon logo.
did i do something wrong?
i would assume due to the fact that the bootloader is not its bootloader it froze/locked up , so heres my question if i flash the non dev friendly one , can that bootloader be unlocked or its better not to risk it?

Since there no tut regarding an unlocked version of this update I simply updated from bpb1 to qa1 , just needed my modem to be somewhat up to date , but it seems that it's def a tx rx issue in my case , so my best bet is a custom kernel with that feature included.

I didn't think a tutorial was necessary as I've never had to give one in the past. If your device is unlocked, you should know it. That's the only reason there is a Dev Friendly version of the update. It won't unlock your bootloader, but it won't lock it if it is unlocked. That's the only reason I make a Developer Bootloader Friendly version of updates.
If you want to update your modem but not the firmware, open either of the files in 7zip/WinZip, extract the modem.bin, then repackage it as a .tar file and flash it in Odin.

In regard to your previous post, there is no problem with the MD5 for either file or any problem with the files themselves. I test them both before uploading them to prevent problems like this for people. I flashed the Dev Friendly version on both of my eMMc 15 S5's and experienced zero problems. The phone will hang on the "Verizon logo" for a minute or two at first boot but it will go past it and continue to "Optimizing" after that.
If you flash the Stock version, if your bootloader is unlocked, it will lock it and in order to re-unlock it, you'll have to use jrkruse's unlock method which requires you to go back to PB1. As of this post, he has not created a QD1 bootloader unlocker. The latest bootloader unlocker he has created is for QC2, which still requires you to have an unlocked bootloader prior to flashing it.
EDIT: Also, if you use an app like Package Disabler Pro to disable applications without root, it can cause updates to hang indefinitely at first boot if you don't re-enable all disabled applications and turn off/remove Admin rights for Package Disabler Pro prior to updating. I've experienced this in the past with both of my S5's and my S7. I'm not directing this at you KazuDante, this is just a warning to all.

No. The Developer Bootloader Friendly version is just that, friendly to devices with a Developer Bootloader. Meaning it won't remove Developer Bootloader status/lock the bootloader.
If I had figured out a way to help all of the eMMc 11 people unlock their bootloader, I would've made a thread that clearly stated that.
I think the only way people with Toshiba eMMc's will get an unlocked bootloader is if either
A: Verizon provides an update to unlock the bootloaders on all S5's AFTER they stop putting out Security Updates, which is highly unlikely since it is Verizon, they've never done it before, and there's no end to Security Updates in sight.
B: Someone at Samsung or Verizon leaks an engineering bootloader. This is the most likely scenario since it's happened before. First, in my experience, with the VZW S3, and the latest being with the S7. There's still hope but it may rely on someone from within Verizon or Samsung feeling bad for us.
Sorry
@Dudash Any idea how to go from the Dev-friendly QD1 version you uploaded to a TWRP flashable zip file which resembles the jrkruse VZW_QA1_STOCK_ROOTED_DEODEXED.zip? I really like to debloat and root before flashing. Thanks!

This is basically the same thing they are doing with other devices. Since Samsung never released their September Security patch due to them addressing the BlueBorne problem, they have been re-releasing the QH* updates as QI* but they include the BlueBorne patch. For some reason, Verizon didn't include the BlueBorne patch in the changelog like they have been for every other phone.
For example. The Galaxy S6, Galaxy S8, and Galaxy S8+ updates all say
Includes: Blueborne security patch

Who knows why they chose to include the exact same changelog as the prior update with the same security patch. Whatever. Verizon sucks. We all know it.

Also, I'm not sure how much longer I'll be doing this though because the screen on my S5 is going bad (flickering and flashing green whenever I bring it out of sleep) so this weekend I'm getting an S8+.
so its safe to say that the new modem ql2 is pretty much the same sa the previous update?
Updated to this build from QH2, flashed in odin, then booted up, reflashed TWRP and SU, froze system updater all good. If you do end up leaving, this will just be another loss for this model as no one else is updating the stock images anymore.
Thank you for your work on this. Does this have root, and if not, do those of us with locked bootloaders have a way to keep root and safestrap?
Tell us how the S8+ goes and if you can unlock the bootloader and root that. Thanks again!

For the record, this loses root, and loses safestrap. I'm too dumb to know how to root this since I can't get TWRP on this phone, so I'm going to hope the way back to root and safestrap is get back Kitkat and then up to PB1 starting over using these steps.. This will probably be better for someone who knows what they're doing or just wants to upgrade for the security updates and doesn't care about root.

I have a 15 Emmc chip and unlocked the bootloader via this thread: https://forum.xda-developers.com/ve.../testers-required-easier-root-method-t3561529
I flashed EMMC_15_VZW_QB2_STOCK_MAGISK_ROOT.zip to my phone. I also have TWRP installed.
Now, if I understand all this correctly, I can simply flash your Developler Boatloader friendly version via TWRP? This will upgrade my OS to the latest update? Then flash Magisk to get root back?
This all seems too simple.
You will also have to re-flash TWRP via Odon.

I too followed the instructions in the thread above for a CID 15 eMMC.
I was unable to flash the "G900VVRU2DQI2_G900VVZW2DQI2_G900VVRU2DQI2_HOME_No_ Aboot.tar.md5.zip" from the OP using TWRP, but was able to do it no problem using Odin 3.12 (AP option).
After flashing that I then used Odin again (AP option) to flash the latest TWRP (https://dl.twrp.me/klte/twrp-3.1.1-0-klte.img.tar.html). I then did another factory reset on the phone (since I had already just wiped my data following the bootloader instructions) and reinstalled Magisk from TWRP and MagiskManager.
Everything looks great so far. Thanks for this update OP and for those of you providing guidance.
I have G900VVRU2DPD1 with unlocked bootloader and twrp 3.0.0-0.
Can I flash the
Developer Bootloader Friendly/No Aboot No-Wipe Firmware:
G900VVRU2DQI2_G900VVZW2DQI2_G900VVRU2DQI2_HOME_No_ Aboot.tar.md5.zip ?
If yes, after flashing, will my bootloader remain PD1 unlocked? Is it OK to have unlocked PD1 bootloader with DQI2 firmware?
Will the TWRP and root be lost? And how I can get back TWRP? Using ODIN? If root is lost then can not use flashify to flash TWRP.
If using odin to flash TWRP, then I can just flash supersu zip in zip to get root back, right?
Thanks.
I guess this is slightly off topic since it's not about this specific firmware version, but here goes ~
How do you guys go about extracting firmware/modems from stock ROM updates?? It boggles my mind lol. I'm running a OP3T now, but am working on an old device (and I still have my old S5 too). Over the years it appears people are now able to do this process for most devices and make it flashable one way or another.
I wish I understood how this gets done (and possibly figure out how to do it myself). Would love a guide / video / brief explanation with terms I could look up if it's long & involved??
Thanks for the work!

Stock ROM update is just a tar archive with files inside.
The names of the files are mostly self-explaining.
Use some tool to access the archive, like Total Commander or 7zip archiver.

Just pack what you want into tar archive and it will be flashable.
No need to attach checksum.
But it's possible too.

Can I reuse the same Magisk from the "EMMC_15_VZW_QB2_STOCK_MAGISK_ROOT.zip" file from the other thread on how to unlock bootloader and root, or should I download the latest Magisk and MagiskManager?
Edit 1: Okay, I installed Magisk after updating to the latest QI2 and am rooted. However, I found that I'm missing busybox and safestrap. Do I have to reinstall both of those as well or can I just reinstall busybox?
Also, QI2 lost tether/hotspot capability as it reverted back to asking to purchase the service (I'm also on the old grandfathered unlimited plan)...is there a way to get it back as when on rooted QB2?
Edit 2: Did some more research while hiding at work...so now I know, having TWRP recovery is enough and just need to reinstall busybox.
Now still need to find a way to get hotspot capability back like when on the rooted magisk QB2...

hello everyone,
i have S8+ with android 7 installed, not rooted and still didnt get any OTA for either oreo or Pie, so i decided to do it manually but i wanna make sure of the steps since it's been a while for me not flashing anything.
first thing i should know is that this update is going to wipe my phone due to the bootloader update
and about that bootloader update, should i flash pie bootloader first or just flash a stock ROM with odin that includes bootloader file ?
any help with this issue is much appreciated

If you are going to update with Odin flash full firmware. ( 4 files )
As for wiping your phone when you unzip the downloaded firmware there will be 2 CSC files.
CSC - Clean install will wipe your data ( same as factory reset )
Home CSC - Dirty install should keep your data
Always do a backup before doing anything.
Note: Make sure after you upgrade your firmware to update your apps so that they will be comparable with new firmware.

Can only install official binaries message when flashing TWRP with Odin3 on A750FN U4

Hi, I'm having a lot of trouble trying to install a custom recovery. I had it working a couple months back but wanted to go with official again for dumb reasons and now i want to go back but it won't let me flash TWRP, i can't find a TWRP specifically for this version either. It's Android 10 with March security patch.
I hope someone can help me.
Thanks.
Please only create one thread per topic. I've removed the duplicate thread you started on this topic.
As far as your issue goes, I don't actually know much about Samsung specifics, but I believe that particular message means you haven't unlocked your bootloader. You'll need to do that before you can flash custom stuff.

As far as your issue goes, I don't actually know much about Samsung specifics, but I believe that particular message means you haven't unlocked your bootloader. You'll need to do that before you can flash custom stuff.

I had previously installed twrp and was trying custom os until one os (evolution x) for some bricked my phone and i had to flash the stock firmware and after that when i try to re-flash twrp through odin it is saying officail binary can be flashed.

Like I said, I'm not 100% on Samsung shenannigans, but have you checked to verify that you didn't lock the bootloader as a part of flashing the stock firmware?
OEM unlock toggle in Developer's Options
Hi ¡...
1. You have to reinstall via odin the latest version 9 (AP, BL...etc)
2. On reboot do the entire TWPR flashing process for android 9
The current problem is that there is no TWPR for android 10.
Cheers
