QJ3 updated bootloader

QJ3 <stock sprint> updated the bootloader from v4 to v5. Just a heads up for those of you wanting to flash the U firmware and getting errors.
So, probably a dumb question, but what do I need to do to avoid the errors? I messed up trying to flash a T-Mobile rom right after updating the firmware, and now I can't boot. I can get to download mode, but can't find a firmware that will flash without failing.
From what reading I've done, I need to find a newer firmware than the one that was on my phone originally, but I can't seem to find anything that will work.

You should be able to flash QJ3 or maybe the latest tmob one. Check sammobile or updato... Just checked, not posted yet. Have you tried a Google search for the qj3 firmware?

Thank you, I wasn't sure what the latest version is so that helps. I did try flashing the latest T-Mo and Sprint firmwares on both Sammobile and updato.com, but it looks like neither are newer than QJ3 so I guess that's my problem. I'll just search or wait to find a new version posted. This phone isn't a daily driver so it's not critical right now.

I had the same issue and just loaded the latest PIT. It allowed me to start my phone with my old Sprint OS.
Here is a version of the QJ3 zip for odin.

You should be able to flash and restore your phone

Thanks so much, this worked perfectly.
Has anyone tried going to the u firmware via pit file? I remember this working in the past. You have to flash the version pit file and previous stock rom, then you could flash the u rom.
Is there any way to downgrade bootloader from P version and then install U version?

Maybe. About a year ago, you could load a PIT file. Not sure if that method works with the newest bootloader. @spamforme mentioned something about it a few posts ago.

Right now there is no way to downgrade to install the U version software. Sprint upgraded to the version 5 bootloader and is the only carrier in the US to do so, so you can't install any other carrier software on your S7 or S7 Edge right now once you have Sprint software installed on it. I have a SM-G930U I took to sprint this past July under the 1 year free service before taxes promotion. Fully unlocked version I purchased online, after having trouble installing a Sprint sim, I had to go in to the store to get the phone to activate.
Once activated Sprint sim locked my unlocked phone(found this out 2 months later when I tried to put another sim in it.) At this point it was still running the SM-G930U Unlocked firmware. I escalated a sim unlock request in September, 2 months pasted and they still didn't unlock my phone. I ended up having to go back in to a Sprint Store to facilitate the unlock, and during that process the Sprint store, flashed my phone to 5BQJ3, that being said, after they did that to unlock my phone they were unable to put the Unlocked firmware back on the phone in the store, I have failed to put the unlocked firmware back on my phone since also, I have escalated this to Samsung, as my phone is under warranty and Samsung say there is nothing they can do. So Sprint sim locked my unlocked phone, and during the process of getting my sim unlocked phone back unlocked, they hijacked my phones software and put all the sprint bloatware and malware on my S7 SM-G930U unlocked phone, and it can't be removed currently as Sprint is the only carrier using bootloader 5 in the US.
I ended up filling out a complaint with the FCC about this last week, and waiting for Sprint to respond as the FCC filed the complaint with Sprint on December 22, 2017. and they have 30 days to respond. But I have tried everything I can think of to get the phone back to the U version software without any resolve. As far as I am concerned Sprint owes me a replacement Samsung Galaxy S7 Unlocked phone or newer model, and right now the only "Unlocked" variant Samsung phone Sprint even stocks is the new S8 Active SM-G892U phone which is the same phone for Sprint as it is for T-Mobile; but we shall see what happens I am not holding my breath with Sprint and will probably just have to take them to small claims court for the replacement cost of my phone as it is cheaper than submitting a formal grievance with the FCC is the informal one doesn't solve the issue.
is there any other carrier firmware with the same bootloader version that i can flash to? i need a phone for Verizon, i'm stuck on the sprint firmware. there's a band that is disabled on the sprint one. hopefully one of the others, if there is one available, will have the bands needed enabled.

Wow - nice persistence following up with FCC! Would love to hear how that gets resolved. I'm also stuck with a 930P v5 bootloader and no way to install 930U firmware. What is the best way to track 930U firmware bootloader versions so that I know if/when v5 is released?

G930UUES4BQL1 is bootloader 4.
G930UUEU2APG9 is bootloader 2.
G930PVPU5BQJ3 is bootloader 5.
At the end, go 5 digits back and you will get the boot binary version. So when the U firmware gets to G930UXXX5XXXX it should be good to go. Based on the U history, it looks like the bootloader will get updated if/when oreo gets dropped to the device. It seems like they went with 2 for MM; 4 for Nougat; and hopefully 5 for Oreo. Every carrier seems to be updating the bootloader version about 5 months before the actual release of the new OS...maybe that means that Sprint will be the first to receive Oreo.

Thanks so much for the great info!
If we wait for oreo and it has bootloader 5 then it will be great assuming we do not update the sprint oreo first potentially changing the bootloader version number again. Would be great but I guess now we will just wait and see

Upgrade old firmware on VZW unlocked phone to ATT

Hi,
I'm a little confused here. I want to upgrade my firmware on an unlocked S8 I bought SM-G950U and it's currently running G950USQS2BQL1 which is VZW FW but I have att as a provider.
To update my firmware do I flash VZW FW or can I flash ATT FW? If I'm able to flash ATT will updates be pushed OTC from now on? Also is there a way to upgrade without wiping the data? Lastly, can I update straight to Oreo (one again without losing data?) The OTA function never provides any updates.
Thanks.

Flash the US XAA firmware and you will get rid of all the carrier bloat and get updates straight from Samsung servers.
If the S8 is unlocked then you can just pop in the Verizon sim and it'll ask to reboot and then you'll have the ATT FW.

What month security patch are you on? If its the November or later it should switch to an ATT S8 after it asks you to reboot. If its earlier then yea you'll be a verizon(doesn't have to be active) sim to get it to take the OTAs to being you speed, and then it'll change to an ATT S8 after asking for a reboot.
Edit: You don't have to flash a different carrier version, it'll change itself on the newer FWs to match whatever sim is in the phone.

AT&T S8+ won't update after unlock and carrier switch

Sorry guys, complete amateur here. I have an AT&T S8+ that was unlocked using a code from AT&T.
I switched to T-Mobile and my phone worked perfectly after simply inserting a T-Mobile sim.
Carriers push updates over the air and I assumed I would have put in an AT&T sim to get the oreo update, but it's been out forever and I have not been able to update my phone. I've been busy and never got around to it. My phone was working fine so I just it slide.
I've tried using an AT&T sim. I've restarted my phone with the AT&T sim in it. I've tried manually searching for the update. I've tried smart switch. I even went to the Samsung experience store in NYC and they had no solution. My phone will not update.
Any suggestions?

I've been reading some of these threads and I'm not sure if this is correct, but I can use Odin 3.13.1 to flash to CRB9? That would get me to the first Oreo release?
Sorry if this is not the correct place for this thread. Thanks

SM-T827R (US Cellular) flashed with T827V (Verizon Oreo) - Working no issues

I purchased a US Cellular branded Tab S3 to use on AT&T when I found out they sell them unlocked. I also recently wanted Oreo on it and after some digging found US Cellular still hasn't released an update but there was one from Turkey and one from VzW. I tried to find a concrete yes/no if I can flash other variants of the T827 models firmware without luck so figured I'd roll the dice on it myself. This weekend I tracked down the VzW Oreo firmware and used Odin to install it on my US Cell Tab. The first round I had a couple of errors and for a second thought I had a new paper weight, but kept calm and ran through the process again and it worked!
Just a note:
At first boot it will say the SIM is invalid and to put in a VzW SIM, but you can click ok and keep going. Once done setting up on wifi you can then go into settings and add the AT&T APN and connect over cell.
Could you post where you got the VZW image? I'd like to try this. I can't believe USC hasn't updated their tabs yet. I'm tired of asking when the update will arrive!

Not sure that was a good idea. If indeed you did manage to flash the VZW bootloader then the tablet is now likely bootloader locked with no way of returning to its original state.

Was this verified to be the case? Also would the verizon combination file work on the uscelluar tablet? I picked up a cheap SM-T827R4 that is FRP locked. I am waiting to hear back from the original owner if they would be willing to bypass the verification for me.

I was able to flash the combo file for the SM-T827V (Verizon version of the Tab S3) to bypass the FRP lock. I used the one on gsm-firmware.com After which I was able to reflash the uscelluar firmware from sammobile. I don't know if this is exactly the same as the OP's method, but hope it helps someone else out in the future.

Sorry for the late reply on this. I downloaded the image files from sammobile and installed them with odin. I've been up and running on Oreo (VzW branded) since my post and have had no issues or reasons to flash to anything else. I have tried to run an update but it says it can't register, which i assume is because it's hitting the VzW servers w an ATT SIM from a USC device!

You just need to put a Verizon SIM in it once (and so far only once) to check for updates. The SIM doesn’t even need to be provisioned. Then you can check for updates with your normal SIM.
I’ve had a VZW Tab S3 for over a year that I have been using with AT&T. I updated to Oreo without any issues with my AT&T SIM installed.
Wanted to first say thanks for the tip -- and echo that The T827R4 does in accept the Verizon Oreo firmware via the latest version of Odin, though with a build just a few releases behind it threw an error and would not flash.
I guess if we can't have root we may as well have Oreo.
Samemobile has the January security update Oreo

You're right about Verizon firmware running really smooth. Much better than the US Cellular firmware. After flashed VZ firmware, the model changed to SM-T827V.
in case anyone has the us cellular model, you really don't need to flash the verizon firmware because the us cellular model has a more updated firmware than the verizon model.
the model is actually SM-T827R4, oreo with apr 2019 security and OTA update works too.
though no pie update yet (same as verizon)
So these can't be flashed to the stock 820 pie rom?

AT&T model and lack of updates

Hello. I wanted to ask about a problem that I have experienced with the S10+, which I know others have experienced as well, and hope there is a solution out there for it. I purchased the S10+ directly from Samsung, as they were offering a much better trade-in deal. However, I did purchase the AT&T version.
That being said..aside from the 2 fingerprint reader updates Samsung has issued, I have never received an OTA update from AT&T. Not a single one. I've had to come here to XDA, hope that someone posts the latest update files, and update using Odin. It appears that those files are being posted less and less. I'm "stuck" on ASGB update, with the July 1 Security patch.
Does anybody have any advice, or suggestions on how I could go about getting regular OTA updates? Or is there other recommendations on what to do here? I know there are many others that have this same problem.
Thanks in advance

Are you using an AT&T SIM card? If you purchased an AT&T model AT&T sends OTA updates whether you got it from AT&T or Samsung. If you aren't using an AT&T SIM they won't send you any OTA updates and Samsung only sends OTA updates to the carrier free versions of the phones.
Yes, using an AT&T SIM card. In fact, I went to the local store and requested a brand new sim, just in case. That obviously didn't work either.

All US S10+'s are the same. There is no such thing as a AT&T or Verizon phone on the S10+. That being said you can load any rom from any vendor on your phone. If you want to stick with AT&T and don't mind their bloat apps you can go to www.sammobile.com and download the latest AT&T rom and load it with Qdin. Make sure your sim card is installed when you reboot and you will have an AT&T phone when it is done.

Prior to August or September firmware on the S10+ was not all-inclusive. If you used an unlocked AT&T S10+ with a different carrier's SIM the AT&T firmware stayed rather than updating to accommodate the inserted SIM card. AT&T doesn't send OTA updates to phones running AT&T firmware if a non-AT&T SIM is inserted and as long as the AT&T firmware is installed AT&T is the only place you can get an OTA update from. You can't even update with SmartSwitch because it will show that you have the latest firmware regardless of how old it is.
I purchased an unlocked AT&T S10+ in early July that was on the February security patch and have a T-mobile SIM. The only way I could get software updates was to manually flash the U1 carrier free firmware with Odin. Immediately after flashing that firmware multiple OTA updates showed up for my phone.

AT&T offers a modded version of SmartSwitch that you can download from their website. You might be able to update to the most current AT&T firmware using their software which is called AT&T SmartSwitch. The standard Samsung SmartSwitch program doesn't access AT&T servers and won't update phones with AT&T firmware.

Why did I have to pick the carrier when purchasing the phone via Samsung? I could have selected the unlocked version, or any of the american carriers. I have the AT&T model. I see the logo when I boot up, and have all their bloatware apps. So that's not the issue. The issue is why haven't I received an OTA update, ever?
I use this threadhttps://forum.xda-developers.com/galaxy-s10/how-to/att-ota-ota-updates-t3909697 to manually update. The OP hasn't posted any new versions in a while.

You might be able to update to the most current AT&T firmware using their software which is called AT&T SmartSwitch. The standard Samsung SmartSwitch program doesn't access AT&T servers and won't update phones with AT&T firmware.

happen to have remember the thread which had the carrier free firmware?

Why did I have to pick the carrier when purchasing the phone via Samsung? I could have selected the unlocked version, or any of the american carriers. I have the AT&T model. I see the logo when I boot up, and have all their bloatware apps. So that's not the issue. The issue is why haven't I received an OTA update, ever?
I use this threadhttps://forum.xda-developers.com/galaxy-s10/how-to/att-ota-ota-updates-t3909697 to manually update. The OP hasn't posted any new versions in a while.

Your OTA updates come from AT&T since you are their customer and purchased the AT&T model instead of the carrier free one. You should really be asking AT&T why you aren't receiving OTA updates.
You might be able to update using AT&T SmartSwitch which you can download from AT&T's website.

I've tried contacting AT&T numerous times. They have no idea what the issue is. A quick google search shows the Smart switch tool in AT&T, but when you try and click on the link, it just takes you to a blank page.
Newer firmware is all-inclusive so you could download firmware with Frija and flash it with modified Odin even if it isn't AT&T firmware. The problem is that if you flash a build number AT&T didn't actually use on their devices you still won't get OTA updates from AT&T because their servers won't recognize the software version you are running.

Have you tried the standard Samsung SmartSwitch program? Maybe it can update AT&T firmware now but it didn't in the past.

If your phone is not carrier locked you could flash the U1 firmware and then you would get OTA updates from Samsung instead of AT&T. But you might not have access to some AT&T services like visual voicemail without AT&T firmware. AT&T also hates unlocked phones so it's possible Volte and Wi-Fi Calling will stop working. Some AT&T customers with unlocked phones were able to get the services activated by calling AT&T but success with AT&T Customer Service is hit or miss at best as you already discovered.
I have the same problem I have been able to update my S10 + AT&T through ODIN, because I cannot update using FOTA, I have the September security patch specifically "G975USQS2ASI6", I want to update to the October patch, but I do not receive the update via FOTA, because I do not use AT&T SIM but I am abroad using with another SIM.
I can Flashear with ODIN to the U1 version that is unlocked, I will not have any problem, I am not interested in losing any AT&T service because I do not use any, I just want to have my S10 + free of Bloatware and always receive updates via FOTA.
I found this Firmware is Sammobile "https://www.sammobile.com/samsung/galaxy-s10-plus/firmware/SM-G975U1/ATT/download/G975U1UEU2BSIP/298471/"
It is the most recent update of AT&T that they have on the official website, but it is G975U1 unlocked and not the G975U. If Flash this version will I have any problem freezing or ruining my phone?

No G975U1 and G975U firmware are interchangeable. If your phone was still carrier locked you might get a message asking for the unlock code but you aren't using an AT&T SIM so your phone obviously isn't network locked. I went from AT&T G975U firmware to U1 firmware with no problems.
Im glad I'm not the only one experiencing this. My wife and I did a bogo deal for the Galaxy s10+ back in March. My phone has recieved updates regularly, while my wife's phone is still on the March patch and security. She hasn't even recieved the fingerprint update fix. Tried calling AT&T about it and they were totally unhelpful. Told me I had to contact Samsung about that and that they couldn't help with the issue. Im debating on calling them back and trying to speak with someone more knowledgeable, but it might just be easier for me to update her phone manually. I haven't had to do something like that in ages, so I wanted to ask for some guidance on here.
Would i need to do each consecutive update she's missed manually? Or would just updating to the newest firmware outright do the trick?

Hey do you have the G975USQS2ASI6 ODIN files? I have been looking all over for it to flash it to my phone.
I just want to note, I am also in the same boat and it's INCREDIBLY frustrating. Both phones purchased in March with the BOGO deal, both phones stuck on the July 1st security patch. Supposedly what I've found after reading quite a bit is you can bring the phone to a local samsung repair center and they can flash the newest firmware, once you're up to date SUPPOSEDLY that resolves the OTA stuff. I don't believe it though.
