[Q&A] Flashtool - Can I flash internal/promoter ROM - Xperia Z3 Q&A, Help & Troubleshooting

Hi,
I was searching for a new firmware and for my model D6653, I found a Firmware thats a lot newer than the one everyone currently use....it has a build number 23.0.A.2.93 but it is labelled as Internal/Promoter. can I download that firmware and flash it? I'm willing to give it a go or flash the stock ftf that sony is cooking now in sweden.
BTW what is that internal/promoter build? How does it differ from the stock fimrware that we all have?

That's an old firmware number, the latest ones start with a 23.4, not 23.0

Yeah. Also, I'm certain internal/promoted builds will NOT work on devices with locked bootloaders, and likely won't work (may even hardbrick) on unlocked devices due to different signing keys between production devices and test devices.

Need help flashing any "customized DE" Firmware.

Hello. Received my Xperia XZ in germany with T-Mobile branding, which i wanted to remove because i do not have t-mobile and all their apps are useless to me, secondly the lot of pink icons / flashing screens / etc. are extremely annoying. I did sucessfully unlock and tried to flash "customized DE" (latest) which always fails (downloaded via XperiFirm, deleted the .xml, packed and flashed with Flashtool).
Then i tried searching an Android 6 tft, and found the "customized CE1" which worked, but did not get the Android 7.0 update yet. But in the end, this is not what i wanted to archive as its the wrong firmware version. As far as i understood flashing Android 7.0 ftfs is currently not possible? And also sony only has latest Firmware downloadable, so no DL-Link for the 6.x Firmware for my region? Did not manage to find the correct Firmware using google.
Can anyone help me out?
Either finding the correct german Firmware ftf for 6.x or how to flashing the 7.x one.
Thanks!

Thanks, but already checked both.
Xperiafirm only finds the newest Android 7.0 Firmware - or is there a hidden "old firmwares" feature?
XperiCheck also lists only the newest Fimware.
Just figured out while writing this post, i can click on the CDA - which seems to list all "customized DE".
Only problem now: I do not have an Alfafile account, nor do i have any of the available payment options to buy me the smallest subscription to aquire this file. :/
Google also does not seem to find any result for "F8331_1305-9090_39.0.A.3.30-R4B_Customized_DE.ftf"
EDIT: That ftf file is not shown in FlashTool - possibly broken one So still no real progress.

Anyway to Flash stock original firmware to my XZ premium prototype?

i have XZ premium prototype one with prototype firmware. I found stock original firmware in Xperifirm so i starting to work on it. after downloaded and create ftf (cant put the right name device for it as it shouldnt support yet for flashtools so i just choose XZ and it created with no issues). but when i start flashing it didnt go, i just would like to know do i need to install anything other than flashtools and device drivers? do i need adb or android sdk inorder to flash it? thanks a lot
You would have to wait for flashtool to support the XZ Premium and then it might not work and brick your device because the hardware might be different slightly from the prototype to the retail model.

Way back in the day when I had a prototype X10i it would only work on the prototype rom, when I flashed android 2.3 or something like that the touchscreen wouldn't work until I flashed back a stock 1.6 rom. It lasted 4 days before the screen went black out of nowhere bricked.
So yeah it's a risk going to another rom other than the prototype one in my experience.
What is the product CDA on your prototype rom? If it is storefront/commercial_journalist then i dont see a issue flashing a other region firmware on it.

Anyone managed to successfully flash stock firmware on prototype unit yet?
Yes I had prototype Xperia XA (F3111) and I successfully flashed both stock marshmallow and stock nougat onto it without any issues. Give it a try. I don't see why it shouldn't work for the XZP.

Flashing more recent stock rom from sammobile

Hi
Apologies for what is quite a basic question for I'm just trying to get things straight in my head before proceeding.
I have a UK retail S7 G930F, current running stock
Build G930FXXU1DQC4
Baseband G930FXXU1DQC2
Despite the fact this build only has Android security patch level February 2017, and the latest build is from 2018, my device and Smart Switch insist I am up to date, I want to actually make this the case while remaining on stock firmware.
I have used Odin to flash Galaxy phones before but not since I had a Note 2 and Note 3 so I'm a little rusty.
I have Odin 3.13.1 and the zip download from sammobile for build G930FXXS2DRAA for the same CSC region I'm currently on which is XEU.
All the guides for Odin flashing say to only use the AP file and option in Odin. However as my BL, CP and CSC will all be older as well, and I'm simply going from stock to stock can I (or should I) also flash these parts as well?
Thanks.
I need more information. 6 mm and 7 nougat use the same BL and require no upgrade where if you were on lollipop somehow you would need the bl. Please DO NOT run off and start flashing things like BL without help from here first. I have bricked a samsung device so bad I had to replace the motherboard, so I learned the hard way.
Both current firmware and the one I intend to flash are Android 7, the new one is just a much more recent build with a more up to date security patch level.
My current firmware, as shipped (or possibly updated OTA a long time ago)
https://www.sammobile.com/firmwares/galaxy-s7/SM-G930F/XEU/download/G930FXXU1DQC4/127501/
My intended firmware that I plan to flash
https://www.sammobile.com/firmwares/galaxy-s7/SM-G930F/XEU/download/G930FXXS2DRAA/205600/
Despite the fact that sammobile says the newer one is available in Smart Switch, it doesn't show any updates when I connect my device to my PC with Smart Switch.

I get that a lot. I upgraded my s7 to latest n release today and it worked ok.
So, do I just flash AP or everything?

You need to flash all 4 files: BL / AP / CP / CSC
I do recommend that you flash CSC* and not HOME_CSC*. That way you will reset the phone to factory defaults and it will be ready for future OTA updates.
Backup your files first that you think are important and then start from scratch to configure the phone, install your apps, update the ones on the phone.

SM-G930U root for v9 Bootloader "G930UUEU9CSA3"

i got the latest security update via OTA and an now running the G930UUEU9CSA3 firmware, ive tried flashing the eng boot img i originally used to root from here "https://forum.xda-developers.com/verizon-s7-edge/how-to/root-s7-s7edge-oreo-nougat-t3819616" but odin fails every time, i'm pretty sure its because the new security update updated the bootloader also... to version 9. now i guess my question is are there any eng boot files for the v9 bootloader available yet? or any other usable root methods available?

That wasn't very clever was it.
Should never update branded unless it's to fix a major bug. Any loophole which allows root or flash is closed on an update until someone figures out how to root on the new boot loader.
I think the best advice to anyone on US networks is to flash unbranded and go from there.

I'm fairly certain that the only twrp for the s7 is a temporary one because there is no unlock for the bootloader, and even still the temp twrp is only compatible with the v4 bootloader and I am currently on v9.... that is unless I'm mistaken if I am then please someone correct me and point me in the right direction because I'd love to be running magisk on my s7 : )

Yes I'm using the modified Odin and all my previous attempts at flashing the eng boot files via Odin on the v8 bootloader have been successful, it wasn't until after the OTA that I started having issues.
And yes this is Qualcomm : )

Hmmm so it may be that loophole is now closed, what you need to think about is if you deffo need root? Or is it just nice to have. I'm sure a dev will get round it soon.

Okay I was completely unaware of TWRP being an option or the possibility of Magisk with a locked bootloader, now to clarify I'm running the latest unbranded US Region firmware for the US T-Mobile version of the Qualcomm Galaxy S7 "(TMB) G930UUEU9CSA3" that being said I have a few questions about how to specifically to proceed if you don't mind helping me?
First is the version of Odin available from the post provided above inst the modified version I've been required to use for all my previous flashing "Odin3_v3.13.1_3B_PatcheD" should I use this one or the version provided in the post above "Odin3_v3.13.1"?
My next question is that all the different versions and variants of TWRP available for my device the Galaxy S7 and the S7 Edge are either for Exynos Canada/International or Korea or the Chinese Qualcomm variant of each. Should I download and use the TWRP for the Chinese Qualcomm S7?
The sammobile link in the original post for "Android 8.0 Oreo Stock Rom" provides me with a list of the latest and up to date international versions of firmware for the Galaxy S7 Edge "SM-G935FD" I'm assuming I should just use the stock firmware image for my device "SM-G930U" instead?
The link for the no-verity-opt-encrypt-6.0 is dead but I don't think its needed because of something someone said in the original post about this method failing after latest security update "the one I'm on" https://forum.xda-developers.com/showpost.php?p=78115895&postcount=18 he said he solved it easily with information and another flash able zip from this post https://forum.xda-developers.com/showpost.php?p=77000849&postcount=47 and the zip from here https://forum.xda-developers.com/showpost.php?p=76564735&postcount=37
All that being said I haven't attempted anything yet, I'll try the above method as I understand it later this evening and I'll post my results

Hello there, i deleted most of your post because i didn't want my post to be huge. So if i just give you some guidelines hopefully you can have a look around for the files you need.
1. For Qualcomm / snapdragon devices you must always use the patched version of Odin you already have. Now this version of Odin can be dangerous if you don't flash the correct firmware for your device because it ignores device mismatch and other safety measures the normal Odin checks for before flashing. Which brings me to.....
2. Anything for G935 will not work for G930 including TWRP, you must always use firmware, patches twrp which specifically says it for G930 Qualcomm/snapdragon devices.
3. The China/ Korea Qualcomm/snapdragon devices are exactly the same as the US devices, anything working on the China / Korea devices will work on the US device.
Now i know you want to root unbranded on V9 but as you are on the T Mobile network it may be easier to flash and root T Mobile Oreo for the time being until there is a workaround root for V9 unbranded.
All of the threads you linked to were for G935 devices and i've mentioned you can't use those patches BUT the process and step by step instructions you follow are the same for your device. So you can follow those guides as long as you are using the patches for your device.
There is a Snapdragon section on this forum so thats a good place to look.
I've had a quick look for this specific firmware and can't find anything about rooting the U9 version yet.....
I'm just checking this firmware G930UUEU9CSA3 your running did have either XAA or USC code next to it when you downloaded? I've noticed Verizon, AT&T and Sprint are using the same firmware VZN, ATT, XAS.

I'd be interested to know how this turned out if the device with V9 bootloader could be rooted with temp TWRP method.
Can i actually flash magisk on my 930u?
Is there any way to root my g930t ?
I'm on v9 bootloader, and i don't care about knox tripping.
Did developpers really failed to break the security of this little old device ? Or no one worked it ?

Would this info be applicable to edge models as well? Pretty sure our moderator has moved on as he is disgusted with samsungs persistance in blocking root with new bl versions. Im on an unlocked tmo s7 edge with the u firmware as well.

[Resolved] #Solved# Any Possible Solution to Downgrade Back to Nougat?

Hello all
Been a member here for some time now and have a perplexing issue.
I upgraded a Samsung Device SM T395 to OS Pie 9 and decided I didn't like it. (There are no other posts with help on this matter)
I kept the STOCK roms Nougat 7.1 and Oreo 8 and want to put Nougat 7.1 back on my device , but is proving difficult using ODIN 13.3.1 or any other version of Odin. The result is FAIL, that's using a combination of AP, CSC, CP and BL.
I managed to get Oreo 8 back on it, but want Nougat 7.1 original installed instead.
Can anyone tell me can ADB Fastboot be used to Flash a Stock Rom back on a Samsung Device or is Odin the only method?
I know there are other similar programs like QFIL and Qualcomm that I have used for the Mi Max brand devices.
The device was rooted with Nougat 7.1 originally and I have USB debug set and FRP / OEM lock off also. So there's no problem there.
The last resort (stupidly expensive idea :crying is for me to buy another exact device that has Nougat 7 installed when boxed up!
I don't see how upgrading to Pie 9 and then wanting to go back to the original factory installed rom is a big problem, can anyone explain?
Would a CUSTOM Nougat 7.1 rom work if installed via TWRP ?
I have also come across this COMBINATION Software https://samsungcombinationfile.com/samsung-sm-t395 that is supposed to allow the downgrading of Android software, but hasn't worked as I had been lead to believe.

Samsung firmwares can not be downgraded. This is due to your bootloader version number. The bootloader version is the 5th number from the right of the firmware being downloaded. You can also check in setting - about phone - software info - baseband version ( 5th number from right). You can also tell bootloader number in download (Odin) mode with a line saying AP SWREV B:? : K? : S?. The B is your bootloader number.
Combination firmware works on the same principle in regards to bootloader numbers.
You can only flash the same or higher bootloaders version numbers.
Custom roms will work as long as the bootloader version number is the same ( or higher ) than what is on you phone.

RE: spawnlives. Many thanks for clearing that up, I now understand. Like many other people I have been trying to mix and match BL files from different OS variants to try and trick the device into accepting the main Nougat AP file via Odin, but nothing works.
These NEW combination files suggest that it is possible to downgrade the BOOTLOADER files on certain devices. However I downloaded all that was available for my device and tried the lot and found the only ROM that would flash correctly and properly was the latest one with the Binary 4 Bootloader. The rest would not register in Odin due to MD5 binary error messages.
In download mode my device AP SWREV B:4 K:2 S:2. ( So I have binary 4 which was released in January 2019, I believe). and this must have been updated when I updated to OS 9 Pie , using all the AP, CSC , BL and CP files.
So as you say, the answer is either , look for a Nougat 7.1 rom with a BL file that has a BINARY 4 code. Or buy another device that has the original Nougat 7.1 installed, which is silly really. :laugh:

The best you can do is roll back to Oreo. A new phone running nougat would be the best choice. I don't use custom roms but they all seem to keep up to the latest version. I have not seen one that ( latest version ) that is nougat favoured.

Yes having researched the total list of softwares for the SM-T395 device, it seems the BL was updated to 4 on the 2nd roll out of Oreo 8.1. And having checked ALL stock Nougat variants, there was never any release of 7.1 with a bootloader binary 4!
I presume the BL Binary version is the 5 character from the right on the picture. (underlined red) :good:
It would make sense for Samsung to give the end user a choice what software they want, by keeping the BL version the same or giving a choice of BL selections to allow upgrade or downgrade.
Anyway, I rolled back to Oreo 8.1 with the binary 4 BL. And unfortunately there aren't many CUSTOM roms , nor a working TWRP for the Samsung Galaxy Active Tab2.
Thanks again :good:

Yes the bootloader is 5th from the right.
I don't own a tab2. If no work twrp can be found and you want to at least have root try using magisk and used the patch root method.
Also to avoid possible upgrade turn off automatic updates in setting - software update as well as in developer option - auto update system.

Have rooted the device no problem with magisk and patching the original boot img file. Then flashing patched boot img via odin. Causing device verification to need to reformat the device, resulting in correct root.
Once a device , this device is rooted, no official updates can be installed anyway. When you try to uodate software, a pop up shows as the device recognises the software has been modified.
As for TWRP there ISN'T any version of TWRP available for the Samsung Galaxy Active Tab2 (SM-T395). I have even emailed the makers , developers of TWRP why there isn't one in their device inventory list on their webpage.
So no TWRP, and NO custom roms either for this model.
My concern , was all about finding a valid , safe way to downgrade back to original Nougat 7.1. And until someone can produce a working image with a BL with binary 4. Then there's only one optiin and that is to buy another untampered device with Nougat 7.1 out of the box and leave it un updated. :good:
Thanks for replying.

Hello all
Been a member here for some time now and have a perplexing issue.
I upgraded a Samsung Device SM T395 to OS Pie 9 and decided I didn't like it. (There are no other posts with help on this matter)
I kept the STOCK roms Nougat 7.1 and Oreo 8 and want to put Nougat 7.1 back on my device , but is proving difficult using ODIN 13.3.1 or any other version of Odin. The result is FAIL, that's using a combination of AP, CSC, CP and BL.
I managed to get Oreo 8 back on it, but want Nougat 7.1 original installed instead.
Can anyone tell me can ADB Fastboot be used to Flash a Stock Rom back on a Samsung Device or is Odin the only method?
I know there are other similar programs like QFIL and Qualcomm that I have used for the Mi Max brand devices.
The device was rooted with Nougat 7.1 originally and I have USB debug set and FRP / OEM lock off also. So there's no problem there.
The last resort (stupidly expensive idea :crying is for me to buy another exact device that has Nougat 7 installed when boxed up!
I don't see how upgrading to Pie 9 and then wanting to go back to the original factory installed rom is a big problem, can anyone explain?
Would a CUSTOM Nougat 7.1 rom work if installed via TWRP ?
I have also come across this COMBINATION Software https://samsungcombinationfile.com/samsung-sm-t395 that is supposed to allow the downgrading of Android software, but hasn't worked as I had been lead to believe.

To answer your question of how is downgrading such a big problem, it is due to security reasons, to keep your device as secure as possible with the newest available software and the latest security updates.
