Samsung

@userU0y7xywOyL Don't take it out on me, I'm just a poor user like you. and have no affiliation to Samsung at all I'm just showing you that the updated firmware is actually available, and I believe others on here with S9s (model SM-G960U1)  have actually received the new update ( G960U1UEU6CSI1)  automatically. What is your model? IS it a actually a SM-G960U1?   ... View more

@userU0y7xywOyL assuming your phone is a US Unlocked model, Samsung have released firmware that fixes the problem for your phone - version is G960U1UEU6CSI1. If you're not seeing it via Settings/Software update/Download and install, you'll either have to wait or install it manually from Sammobile. ... View more

@userXJorIBlD70 @Latenighter  Can the people who are saying that a new September update has fixed their problem please provide:-   1. The model of their phone from Settings/About Phone/Model number e.g. SM-G965U1 2. The new formware code from Settings/About phone/Software Info/Baseband e.g. G965U1UEU6CSH7 3. Country they are in e.g. Australia 4. Name of their service provider e.g. Telstra   It is a bit useless to the reset of us without that information.   Regards, Graham ... View more

@uservYwQJ1M8F4 Could you please check in your "Settings / About phone / Software information" and let us know what the "Baseband version" for the new "September" firmware you now have on your phone is so we can determined whether it is different than the problem one? Also please advise what model phone (SM-G960U1, SM-G965U1) you have and what country you are in because Samsung release new firmware at different times for different models and countries?   Regards Graham. ...

@usergvWGIz6Pwl Unfortunately that solution did not work for me either. Could you please advise what model phone you have (SM-G960U1, SM-G965U1 etc) because I think there are a couple of different issues, one that can be fixed by that method and one that can't? Regards, Graham. ... View more

Hi Latenighter, While some of what Samsung told you is true, I'm afraid it would appear that much of it isn't, and whoever is giving you that advice perhaps needs some more training. I understand that Odin is actually the product that Samsung use internally to flash devices and while it is true that it can be used to rooot devices, when used to flash factory firmware it does no such thing.  Flashing factory firmware does NOT magically give superuser access or rooot your device. Most other manufacturers (even Apple) actually allow and encourage their customers to reflash their devices themselves and provide the software and firmware to do so! I don't believe that it affects your warranty (whatever that might be worth for imported grey market devices). There is a "phone status" flag that is set if  "non offical" firmware is installed, but it isn't set when installing offical firmware like the previous good version in this case. Also, it does NOT stop the receiving of future updates as I can attest with my phone still prompting me to install the latest (faulty) update, and all of my Samsung apps still work fine. Future updates are only banned when the flag referred to above is set.   Factory reset does not and can not fix this problem becasue the issue is with the firmware itself, so don't waste your time doing it again.   I should also perhaps point out that I can't see that there is anything stopping Samsung service centers flashing back devices to the previous version as the have access to all firmwares. They might not want to, but I believe that they can!   Regards, Graham ... View more

Hi fellow suffering Samsung phone owners, When posting could people please advise the model number of their affected device as well as their country so we can get a better understanding of how widespread the problem is? This can be obtained from Settings / About Phone / Model number. e.g. Mine is a Galaxy S9+ with model number SM-G965U1 & I'm in Australia. Reading through this forum so far :- Affected devices seem to be S9 (G960U1), S9+ (G965U1), S10, S10+, & Note 8 (N950N). Affected countries: Australia, New Zealand, Philippines, Peru. I suspect we will find that all affected phones are using the Snapdragon CPU and not the Exynos CPU. The US Unlocked (in fact all US Samsung phones) models use the Snapdragon. Currently the ONLY fix that I am aware of is to install the previous version of the firmware on your device. I believe that ALL Samsung dealers can actually do this, regardless of the model or where the phone was bought (they might not want to but they can). As the faulty update seems to still be being pushed out, you also need to turn off auto system updates otherwise the faulty firmware would eventually get reinstalled. To do this you need to enable "Developer options" (please Google to find out how to do that) and then turn off settings / developer options / Auto update system. Regards, Graham ... View more

Hi  userrhCJ8swsKn, I'm guessing the large Australian supplier that you received a response from was Kogan. Don't hold your breath waiting for a patch from Samsung as it has already been six days! I'm afraid that the only temporary solution that I am aware of it to install the previous firmware for your phone as documented elsewhere in this conversation, and it really is temporary because the auto updater almost immediately starts requesting an update back to the faulty firmware. Samsung really need to at least turn off the forced update to the faulty firmware!!! ... View more

I tried to post step by step instructions on how to fix this problem but the moderators for this site keep removing it for some reason that I don't understand!   Last try with the actual links removed - you will need to search for them.   The interim method to fix the problem is to re-install the previous version of the firmware for your phone. For the S9 and S9+ US Unlocked phones (SM-G960U1 and SM-G965U1) the previous firmware has a build date of 30-Jul-2019 and has SH1 at the end of the filenames (the faulty firmware has SH7). This is standard factory firmware and should work with normal untouched phones. You can find instructions on the sammobile website. BACKUP your phone first and read the instructions VERY carefully. Make sure you use the HOME_CSC file and NOT the plain CSC file otherwise you will wipe all your data. Search for sammobile website and do a free registration. Find and download the correct firmware for your phone. For my phone which is a US unlocked S9+ with a model number of G965U1 and a product code of XAA the correct firmware ended with "G965U1UES6CSH1/285290/" Download and install the Windows software called Odin. Extract the firmware file you just downloaded. You should get 5 files: AP (System &Recovery) BL (Bootloader) CP (Modem / Radio) CSC_*** (Country / Region / Operator) – DO NOT USE THIS ONE!!! HOME_CSC_*** (Country / Region / Operator) Add each file to it's respective field in Odin. Make sure you use HOME_CSC_*** and not CSC_*** if you want to keep your apps and data. Reboot your phone in Download / Odin mode (make sure your device is off) with the following button combo: POWER + VOLUME DOWN + BIXBY Once in download mode, connect your phone to the PC, preferably using the original USB cable you got with your phone. Odin should detect your device and a BLUE box will show up with the COM port number. (Be sure, the SAMSUNG-drivers are installed on your PC!) Do NOT tick any extra boxes. The only options to be ticked are F.Reset Time and Auto-Reboot. Click the start button, wait for Odin to say 'PASS' in a GREEN box. Once the flash is complete, your phone will reboot, and you can disconnect your phone from the PC. Once the phone has restarted turn off “Auto download over Wi-Fi” under “Software update” in Settings, otherwise the faulty firmware will automatically get re-installed again! ... View more

I have fixed my S9+ (G965U1) by reinstalling the previous firmware. ... View more

FIXED In the absence of any action from Samsung I have fixed my US unlocked S9+ myself by installing the previous firmware version (build date:  Tue, 30 Jul 2019 07:04:54 +0000). All the issues have gone.   Differences bewteen the faulty firmware and the previous are with  Baseband version G965U1UEU6CSH7 -> G965U1UEU6CSH7 Kernel version 4.9.112-16578910 -> 4.9.112-16002534 Build number PPR1.180610.011.G965U1UeU6CSH7 -> PPR...SH1 SE for Android SEPF_SM-G965U1_9_0008 -> SEPF...0002 Service provider SW ver SAOMC_SM-G965U1_OYM_XAA_PP_0022 -> SAO...PP_0021 Sercurity software version is the same (both are 1-Aug-2019)   Firmware and Odin updater sotware is available from... https://www.sammobile.com/samsung/galaxy-s9-plus-us-unlocked/firmware/SM-G965U1/XAA/download/G965U1UES6CSH1/285290/ You will need to do a free registration for this site to get the firmware for your phone.   In settings I have also turned off "Software update / Auto download over WiFi" to stop the faulty updater from re-installed again.   Regards, Graham ...

Samsung have essentially bricked grey market phones in Australia and New Zealand. Their sluggishness in fixing the problem is in-execusable. I think news of this problem perhaps needs to be spread a bit wider. If it became more widely known in the US that their unlocked phones won't work overseas I suspect there would likely be a significant backlash against Samsung and loss of sales, and Samsung might try a bit harder to fix the issue.   Currently the only fix is to re-install  the previous firmware version for your phone and somehow disable automatic updates to stop the latest version from installing again (I'm unsure how to acheive that). ...

The interim fix is to downgrade to the previous firmware for your phone. A link to that firmware was posted on one of the other conversations of this site. It is for the S9+, but firmware for the S9 is also available there. My concern for this solution is that the latest firmware will eventually automatically get re-installed again and I'm unsure how to stop that happening. It would appear that Samsung are not in any hurry to fix this problem.  https://www.sammobile.com/samsung/galaxy-s9-plus-us-unlocked/firmware/SM-G965U1/XAA/download/G965U1UES6CSH1/285290/  You will need to find the correct firmware for your phone by referencing the model number - in my case,G965U1 for my US Unlocked S9+. You will need to do a (free) registration with this site to be able to download the firmware. You want the firmware dated 30th July and security patch level dated  2019-08-01 and with SH1 at the end of the firmware name. The firmware with SH7 at the end is the bad one. Regards, Graham. ...

I also am now getting the dreaded 'IMS Service Keeps Stopping' message directly after installed the latest updates this morning 7th Sep 2019 on my Galaxy S9 Plus. I have tried all the suggestions mentioned including as a a last resort doing a hardware reset. The message came back immediately after restarting after the factory reset before even restoring anything - this suggests to me that there is a serious problem with the latest updates. The phone is now essentially unusable in that it is very unresponsive and the battery goes flat in about 3 or 4 hours!   Update version: G965U1UEU6CSH7 Size: 630.81 MB Security patch level: 1-Aug-2019 ...
