[Galaxy S 5 Q&A, Help & Troubleshooting] Laugh2:
Thank you, GRWButt and Fear_the_Fluff, for your suggestions. Since then I've tried the following:

1) Factory reset both in Android and in TWRP i.e. wipe Dalvik, Data, and Cache​

2) Installed Stock ROM (twice)​

3) Installed LineageOS 17.1 and also 18.1 (repeatedly)​

4) Installed and run Avira Antivirus (which didn't find any issues)​

5) Wiped Dalvik, Data, Cache,

and System

before flashing (repeatedly​

(all with neither SIM nor SD card installed). None of these 5 attempts made a difference.

I cannot reboot without this issue arising, irrespective of whether I reboot from Android or TWRP. However, if I remove the battery for at least 5 minutes then I can boot the phone normally, the Samsung flash screen appears normally, and then Android loads and runs normally too. Often though the phone the freezes but sometimes it works as normal.

Is it possible there is a virus or other malware (e.g. akin to rootkits for computers) hiding in the Samsung flash screen or in the boot sector, and which is successfully hiding from view and from scanning by Avira?

[Edit]

Later: I've flashed Lineage 18.1 multiple times using TWRP along with MindTheGapps and gone through the setup. After installing Avira then rebooting several times the problem was reduced to only a quick flash of the visual "noise" across the bottom ca.20% of the screen on reboot. (It didn't happen at all after removing the battery and waiting 15min or so.) This was a vast improvement over having the entire screen showing the noise and becoming useless after each reboot.
[Galaxy S 5 Q&A, Help & Troubleshooting] juandante:
Your problem looks like first a typical internal cable connection, or second battery problem. Third, could be an eMMC issue also, in this case you must either reflow, either change the S5 motherboard. I didn't read all your message (to long), but if you have a new battery try ordering one from a different supplier/brand. Already happened to me that my battery supplier/brand was just supplying junk.
[Galaxy S 5 Q&A, Help & Troubleshooting] dave678:
You have what's know as screen flickering.
[Galaxy S 5 Q&A, Help & Troubleshooting] Laugh2:
Hi Dave678, Thanks for your reply. The issue on the phone causes freezing of the OS within a few minutes of booting rather than only flickering. However, if Avira is installed very soon after a complete re-flash then there are no more problems except for the brief flash mentioned. Can screen flickering usually be largely solved by Avira (or other antivirus app)?
[Galaxy S 5 Q&A, Help & Troubleshooting] dave678:
Screen flickering is a hardware issue
[Galaxy S 5 Q&A, Help & Troubleshooting] Laugh2:
That sounds logical. However, I don't think my issue is a hardware issue. The brief appearances (/flashes?) have only ever occurred during initial startup. The freezing and related hiccups have all magically disappeared as soon as Avira was installed. (Possibly other similar apps would've similar results but I haven't tried any others.)
[Galaxy S 5 Q&A, Help & Troubleshooting] dave678:
If you don't think it's a hardware problem then try reflashing stock firmware and see if it still happens. If it still happens after doing that then it's definitely a hardware issue.

Just woundering if this phone can be booted over USB with

Hi Dave678, I've flashed the StockROM from Samsung several times - that would also flash the firmware wouldn't it?
[Galaxy S 5 Q&A, Help & Troubleshooting] dave678:
If you flashed the stock rom then that's stock firmware.
[Galaxy S 5 Q&A, Help & Troubleshooting] Laugh2:
Hi Dave678, The last ROM I flashed was LineageOS 18.1 with Avira installed immediately. The weekly updates have been installed most weeks since then. The phone has been in daily use and stable for well over a month now, and it boots as fast as a second, identical phone I have i.e. same model/LOS18.1/Avira. Currently the problem seems to have disappeared. :)

While the cause is still unknown it is great to have the phone working again in daily use and without problems. Aside: I can certainly recommend the combination of an Galaxy S5 with LineageOS 18.1.

Hi I’ve used my klteduos with LOS 18.1 + Magisk and TWRP 3.60_9.0 for a while when it suddenly froze and I couldn’t get it back running. I tried:

Uninstalling Magisk (no change)

Installing a newer version of LOS 18.1 (no change)

Reflashing the boot.img of LOS 18.1 (no change)

At the end, I simply wanted to regain my app data of Shazam/my heard songs (everything else can be redone) and I saw that the main folders at Android/data/com.shazam didn’t have any files in it. Later I found the app data itself is stored on the root partition at data with some weird ~~7zeuj384… names. I found the previously described shazam folder with that name and made a copy of it.

Now what I would like to do is, to simply reinstall the app and get my previous appdata back. Is that possible?

I remember that Titanium Backup had that exact function when transferring app data to a new phone. Any insight on that?

By now I already went back to stock and went back to LOS 18.1 with a clean install and Magisk root.

Hello everybody! I am new to this forum, and i have some very important question for me.

Is there any decent os for k3gduosctc / G9009D that has speedy OS, decent performance etc?

I have texted to lineage os forum and my phone isn't listed, but the similar phone G9009W is ready for that.

They said that the difference is that G9009W has LTE, and mine (G9009D) not.

Is there any chance to boot my phone if i will load an os from G9009W to mine?

Or if i will try from the global version (KLTE) ?

I have really almost lost any hope for the new os for this chinese buddy...

(The current os is android 6)

Hi All,

I'm new to XDA. I've searched these forums to the best of my ability but I've not found what I'm looking for. I'm on Verizon. I purchased an unlocked mint condition Galaxy S5 SM-G900V with G900VVRUDPG2 base firmware (ROM) from an ebay seller. This particular ROM has no Verizon (or other) bloatware. It is very clean. The phone will run for 5 days without needing a charge because the OS is so clean. I want to get a complete backup/copy of this clean ROM and install it on another Galaxy S5 I have that has so much bloatware its killing its battery in less than a day. I asked the ebay seller for a source for the firmware but they none. Copies of G900VVRUDPG2 I get from Samsung and other sources have tons of bloatware so they are no good. I want the clean firmware (ROM) off the new Galaxy S5? How can I do this? Can I do this without rooting (disturbing the ROM) on the new Galaxy S5?

Also, when performing a wipe/factory reset on a Galaxy S5, what is actually happening under the hood? Is a clean copy of the base firmware being copied from a save partition to the /system partition?

I know this is an old phone but I consider it one of the best Galaxy phones made. I know its a lot to ask. I appreciate any help.

Thank you.

[Galaxy S 5 Q&A, Help & Troubleshooting] mtnbkr88:
Hi again,

I have a mint condition unlocked Galaxy S5 SM-G900V running Android 6.0.1 I bought from ebay. The firmware is G900VVRU2DPG2 and *#1234# shows the CSC is G900VVRU2DPG2. The About Phone software area shows United Arab Emerates and booting into recovery shows the CSC is set to XSG (United Arab Emerates unlocked). I live in USA and the phone does not connect to all mobile networks like me old S5 did. I think the problem is the lower level CSC is set to XSG instead of XAA. Everything I've tried to change the CSC to XAA has failed. Does anybody know a sure way to get my CSC changed to XAA on this phone?

Thanks you.
[Galaxy S 5 Q&A, Help & Troubleshooting] It_ler:
Usually the SM-G900V comes with Verizon (USA) > CSC = VZW.

As the G900VVRU2DPG2 is not the latest firmware version, you can try to flash latest version G900VVRU2DQL1.

You can download latest stock firmware on different dowload sites - just search for "stock firmware SM-G900V". There you will also find guides how to flash.

Or just have a look here: https://xdaforums.com/t/firmware-pit-verizon-samsung-galaxy-s5-sm-g900v-kltevzw-odin.3757416/

About changing CSC ... I just know a methode which needs root and doing a factory reset. That is not a "sure way" IMO.

I hope that flashing latest stock firmware will fix your mobile network issue.

Hello Everyone! :-)

I just wanted to get some type of confirmation/clarification of the following question...

With Verizon USA (in its glorious wisdom :-O) had made changes (late last December) that requires all devices, that connects to their towers, to begin utilizing VoLTE.

My question/clarification is that it appears as though none of the Custom ROM's (ie... LineageOS and so on) currently doesn't have VoLTE capability (as of yet).

I'm just basing my question on what I've found (thus far) in researching this.

Thanks a Bunch! :-)
[Galaxy S 5 Q&A, Help & Troubleshooting] curiousrom:
FYI LineageOS does no support VoLTE on any Samsung devices @ the present because the devs could not reverse engineer Samsung's proprietary VoLTE implementation so far.

That could be a deal breaker if your network provider drops 2G & 3G as only VoLTE will work for voice calls after that.

Some providers will even disable data if the device is not currently supporting VoLTE.

AFAIK only custom ROMs based on stock Samsung OS can support VoLTE.

BTW hello my friend!

[Galaxy S 5 Q&A, Help & Troubleshooting] Ibuprophen:
Hello again My Friend! :-)

Verizon did drop 2G & 3G and also requires VoLTE. This affects all Samsung Galaxy S4 and below.

My G900V device is on LineageOS and works with 4G data only with no Voice, SMS & MMS service.

I had a feeling that I'm now down to using AOSP Custom ROM's (at the present time).

I may have to look at the additional option in getting a newer Galaxy or another manufacturers device all together.

What a huge pain... LOL!

Hi!,

I have a SM-G900V from Verizon and everything looks ok except that I cannot get an LTE signal. The tech from my local carrier (Smart PH) said that the LTE Freq is ok but the SM-G900V is on bandwidth 2 and it needs to be on bandwidth 1. I checked the local S5's here and it has SM-G900F on them.

Can I download an SM-G900F from anywhere and flash it on my SM-G900V? Will there be problems?

Thanks!!!!
[Galaxy S 5 Q&A, Help & Troubleshooting] fffft:
Unfortunately, it doesn't work that way. Verizon and Sprint networks - and the phones made for them are different than everyone else. They are CDMA based while everyone else has moved to the global GSM standard.

Neither Verizon, nor Samsung are going to let you simply program 900F (GSM) features onto a phone meant for Verizon CDMA. Verizon is trying to make it hard for you to leave and Samsung wants you to buy a new 900F phone if you do. It's worth double checking since some a few carriers have hybrid networks that overlap. But it sounds like you probably have the wrong handset for Smart.

If you had another GSM phone e.g. a 900T, you could probably do it. But the 900V and 900P are the odd ones out. Wish we had better news for you.

[Galaxy S 5 Q&A, Help & Troubleshooting] fffft:
There are specific things that will trip Knox. Installing a custom kernel or recovery. Trying to replace a locked ATT or Verizon bootloader. Downgrading a Kitkat bootloader to an older Jellybean one. An older rooting exploit.

If you are careful, you can still install stock firmware, use newer rooting methods, etc withoit tripping the Knox flag. Also a lot of people don't care about Knox. Samsung will try to deny a warranty claim if Knox is tripped. But a lot of carriers e.g. TMB don't care about Knox and will still honour your warranty. And the EU does a much better job of protecting consumers against Samsung's unreasonable position that rooting should invalidate the warranty.

If you are careful, you can flash stock firmware, root with newer methods and debloat or freeze apps without tripping the Knox flag.

Problems with ART runtime

So an hour ago I decided to try ART on my S5 (international Qualcomm variant/not rooted) and now i'm having problems with it. It took about 15 minutes to optimize 400+ applications and now everything stopped working. The first thing I noticed was that the TouchWiz launcher was crashing over and over again. Then I decided to open the settings via the notification bar on the lock screen so I could switch back to Dalvik, but it also didn't work. The application crashes every time I try to open it. So I rebooted the phone and it was still optimizing about 40 applications and nothing was working. The only thing that works is the lock screen, some report-bug app and the notification bar. And the phone is alerting me that the storage space is running out.

Can someone please help me so I can at least recover some files? I'm desperate.
[Galaxy S 5 Q&A, Help & Troubleshooting] fffft:
As you have found out, ART is not fully supported yet.

First question, did you make a backup? You should have and if you did, then you are entitled to smile smugly. Boot to recovery (hold Power + volume up + home keys simultaneously), then restore your backup. Done.

If you didn't backup your system before it got messed up.. well at least you know how useful backups can be now. It's hard to gauge how corrupt your system might be at this point, so here are several suggestions to recover or at least recover some files in the absence of a backup.

1. Try booting to recovery mode and clearing the cache. Possibly the OS will then be able to recover and transition to a stable boot on it's own.

2. Start an ADB session (lots of threads and tutorials on this if you haven't used it before) and copy those user files or directories that you know the names of to your PC. Most user files will be in the /data partition.

You can also toggle your system from ART to Dalvik from an ADB session.

adb pull /data/property/persist.sys.dalvik.vm.lib

open the file and replace the "libart.so" with "libdvm.so" (no quotes) to switch from ART to Dalvik

adb push persist.sys.dalvik.vm.lib /data/property/
adb shell reboot

3. Erase and dirty flash the system partition. This is a bit of desperation, but I have had good results with it. If you have a custom recovery (or are willing to flash a custom recovery), wipe the system partition and cache only. Do not wipe the data partition as that is where your user files are. Then flash an OEM ROM to restore the system files. This will not normally wipe the user data files. Your system should then be 99 - 100% stable, although some apps will no longer be working and may need to be reinstalled. But still a big improvement and a stable base from which to recover files.

Note that installing a custom recovery will trip your Knox flag if it isn't already. This may have warranty implications depending on what country you reside in and who your carrier is. It may also specifically lock you out of files in the private mode area. So keep those points in mind.

4. If you aren't willing to install a custom recovery, but nothing else has worked.. then try installing the OEM ROM anyway. Be sure to say no if asked whether you want to wipe everything. This will probably work as well, although it's theoretical (to me, anyway) as I have not tried this specific scenario myself.

Good luck. And don't forget to make a backup next time.

"Database cannot be open" notification

Background info:

I recently received and rooted my att s5 (towelroot) and restored contacts, call logs, texts with super backup. Restored user apps+data using titanium. Had to uninstall and re-install each one separately (they all "stopped working" as soon as I opened them) but it's done now. Switched to apex launcher. I also froze knox notifications using titanium. These are the only major changes I have made so far.

Have not activated new SIM card yet, still using my s4 until I get a case for the s5.

Now for the issue:

I have this grey bubble notification near the bottom of the screen that won't go away. All it says is "Database cannot be open". I don't think it's a toast (those are usually blue boxes), and I have no clue what app/action caused it to appear.

Been searching google and XDA for 3 days, haven't found anything yet. Any help is appreciated!
[Galaxy S 5 Q&A, Help & Troubleshooting] MateusMaciel:
Problem solved/thanks

First of all, thank you very much for the reply, but I got lucky, I don't know, and the error messages disappeared. I rebooted the phone a few more times and every time I did that the number of the applications being optimized decreased and I managed to open the settings successfully from the lockscreen.

I AM aware that backups are life-savers and to show how much I care for it, I have two external hard drives always updated with my files and auto backup with Google Drive on my phone, computer and tablet. But I was actually worried about application data and private files that I didn't back up for almost a month.

The reason I switched to ART without getting worried about losing files was that I already did things like that on my old xperia x10 mini pro, and everything worked fine. But yes, it was a long time ago and lots of things changed with updates and all. Also, no one was complaining about the same problem I had. What happened today gave me a heads up about the philosophy "if it ain't broke, don't fix it" and taking backups even more seriously. (And to stop trying to be a superuser).

Thank you.
