[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] chrisrevoltes:
I got two (with the insane speed of 300kb/s) from sammobile.com, and all other with a tool called Frija. Its the successor of samfirm.

The archives are between 2.3GB and 2.8 in size. But now that you mention it I realize that the AP files have different sizes: Newest 2020-10 unbranded german 8.0 version: 2,53 GB (and all other german versions round about as well), but dantexperias 7.0 version had 4,09 GB. Either way I do not know where those values come from in Odin with the german versions.

Alright. Where is that pit file coming from? Like I said, I tried with the pit-file for the newest German version and it didn't work. But yours and mine have different hash values, so I'll give it a try.

Yea, that was in hurry. I didn't think about it in that moment. Stupid I know. Hopefully I have not made it worse by doing so.

Like I said, I already did this. With different german branded versions, because I found two non matching BL and CP files in my archive from 2018. I cant remember if I user those or not.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] chrisrevoltes:
That didn't work. Again aborted with FRP lock message.

But somehow I got it to boot to Android Recovery!! The last thing I did, was flashing BL, AP, CL and Home_CSC with my extracted PIT (from CSC file) and ticking DeviceInfo. After two sec the phone rebooted to recovery.

Now I'm able to boot to download mode and original recovery but not to system.

This is what Recovery shows:

View attachment 5218201

I can wipe data and cache partition, but not system partition.

I can view the logs, but I'm not sure what they are telling me....

I can view my external SD card, but trying to install ether TWRP, LOS or the stock image aborted with an error Update from external storage is disabled following a reboot to recovery. Any idea how to enable that?

ADB seams to be working. It can find the phone, although there is an message Stopping adbd... on the phone.

View attachment 5218209

adb devices -l shows:

XXXXXXXcf0cd263704 sideload product:heroltexx model:SM_G930F device:herolte transport_id:8

Sideloading the stock image or TWRP results in: Total xfer: 0.00x in console and adb status 1 on phonescreen with phone reboot to recovery.

Any other adb command (except those three getter) has ether no effect or results in an error.

Any further attempt to flash again with Odin results in the same errors like described in my last post.

Any ideas? ADB or external storage seams like a good way. But system partition worries me.

Edit: fastboot doesn't find my phone...
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Roberto W.:
u should move this discussion to an other matching thread in this forum.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] dantexperia:
The system error is because the partition is clean due to "nand erase all", try to flash with odin the oldest version for your binary by selecting the option "re-partition", if that does not work try the latest version for your binary marking the same option; If any of the systems is installed successfully, it goes back to download mode but this time installs the latest version of TWRP, once you can access the TWRP recovery you will have the possibility to try different custom roms until you can revive it.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] chrisrevoltes:
That didn't work gegardless how often I'll try it... At this point it just stops with a red FAIL in Odin. Trying with PIT file actually flashes for at, than stucks and fails.

You're right, seams thats not a LOS issue. Moved it here.

EDIT: I have finally made it! Thanks to everyone helped me!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] gallusala:
I also had echo problems.

So I did some tests:

- Put my SIM-card in an old smartphone: no echo problems. So I know, that my SIM-card and my cellular provider are fine.

- Put my SIM-card in my Samsung S7: echo problems again.

- Did a call with the headset: no echo problems.

My solution / workaround:

Settings, Sound, Call volume: I reduced Call volume from MAX to MIN: NO echo problems!

Best regards

Do I need to reformat/wipe my phone again if I wanted to update to newer versions of the rom? The updater does not work
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Mint Julep:
Depands on which ROM your coming from.

If you have the same ROM you can just dirty flash the update, if not, you must wipe and clean install. I'll recomand flashing updates in the right order if you missed some. Please take a moment to go back in the thread : I seem to remember that there's a fork somewhere between 2 version (maybe 17 and 17.1) , where dirty flash doesn't work. Just look for it.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Nevaran:
I just did an install of the new one from twrp, nothing else; and it seems to have worked
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] chrisrevoltes:
The updater works only for "official" ROMs listed here: download.lineageos.org.

There is no need for factory reset or full wipe for updates between one version (here: LOS17.1). But follow ivans instructions if your last version was prior Jan.

Update:

0. Backup with TWRP just in case

1. Install new vesion

2. Install gapps

3. Install magisk if wanted

4. Wipe dalvic cache
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Nevaran:

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] fipsy:
I have been using this OS on a daily basis for 3 months now and am meanwhile just massively annoyed by it. There are so many small and also big bugs that it is completely unsuitable for daily use for me. E.g. in the beginning I was able to record videos without any problems. Since some weeks this is no longer possible. It started with the January release. Since then, I can no longer record videos with any camera app (I have tested 3 apps) when I select the external SD card as storage location (it's a new SanDisk 128GB Extreme Pro, which can handle 1080p video quite easily - so that's not the problem). When I stop video recording, the smartphone basically performs a cold start immediately! The video is then corrupted and the file system of the SD card is also increasingly destroyed. A checkdisk of the SD card with repair did not bring any remedy. The February release also has the same problem. Meanwhile, the cold starts also sometimes occur after taking pictures. But only when they are saved on the external SD card. It is extremely annoying when you can no longer take pictures or film with the device!

Another problem: I wondered why my mobile data consumption increased extremely with this OS. About 5 times. Meanwhile, I also know why: About 20-30 minutes after the device goes into standby, it disconnects the WiFi connection to the router. From then on, all apps only use the mobile data connection. If you listen to audio streams, for example, this means a huge consumption of mobile data. An absolute no-go! Unfortunately, there is also no longer an option to set the WiFi connection to stay active all the time even in standby. In previous OS there was such a setting. Does anyone know if this setting is still available somewhere?

After 3 months of use, I have to say: If I had known all this before, I would never have installed this OS! It is full of small and also big bugs, which unfortunately are not fixed. :-( For daily use, it is therefore completely unsuitable for me. My old S5 with LineageOS 14.1 was much more reliable!

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] MikeTheTechSavvy:
In my opinion it's common sense that a big change such as installing LOS when coming from stock should result in a full wipe and viceversa, I have mentioned that a full wipe is required.

Also, regarding the call echo I haven't noticed anything, I'm not sure if this is due to my device being new but it's something I haven't observed.

Hi @Helmy José,

"hello, I have the February version, to install the March version I must delete some folders from the system or just flash it?"

If you flash Update from your installed ROM you can "dirty flashing" over your running system.

If you flash other Custom-ROM it is better to "wipe" and "format data" : this is "clean flashing"

If your Phone running with this ROM from Ivan_Meler and now is Update available (Update is the same ROM newer) then you can "dirty flashing".

Hello,

what about the untestet things like GPS, Fingerprint Sensor and camera? Are they working? Or is the los 18.1 the bedder choice at the moment?

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] fipsy:
Already since the January release screenshots are no longer included in the gallery! They are only stored in the file system, but not shown in Google Photos or in the gallery. I thought the bug would be fixed, but it is still there in the April release.

When I read what problems some users have with the OS, I'm still well off. What bothers me the most is that the Wi-Fi is turned off after about 20 minutes of standby and then all data traffic runs via mobile data. So listening to podcasts consumes large amounts of mobile data volume quite unnecessarily. Unfortunately, there is no setting that allows WiFi to remain permanently active in standby. A huge drawback!

GPS and fingerprint have been working for me all the time. But the camera is still a problem. When I save photos or videos to the external SD card, it is not uncommon for the smartphone to simply perform a cold boot and the photos or videos are not saved. Moreover, the file system of the SD card is increasingly destroyed as a result.

Meanwhile, I think that these are all kernel related problems, because if you change the kernel parameters with Kernel Adiutor, some problems become less. Therefore, LOS 18.1 will probably not bring any improvement to these problems. I think that the kernel would have to be fundamentally reworked to eliminate all these problems.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Sebastian323:
Hello Fipsy,

thanks for your answere. So saving camera-pictures on internal sd is working?

Perhaps I keep it with the orginginal rom for some more time.

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] fipsy:
@Sebastian323: Yes, it works with the internal SD card. However, the reboot does not happen every time. And it happens much more often with videos than with photos.

Today, the best ROM for the s7 in performance and battery. recommended. Thank you Iván for your great work.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] fipsy:
That's right. But performance and battery is not everything. Stability and functionality are also very important. So this ROM is not bad but also not excellent. I would say it's ok overall. Depending on what you want to do with it and what is particularly important to you.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Don Carnage:
I installed the ROM and everything was fine for a couple of weeks until today. When I checked my phone, I pressed the power button and the only thing I could see was the clock. It goes away after a couple of seconds and I can't do anything else. Holding the power button for no matter how long doesn't do anything. I can plug in USB and the device will be detected but I can't access any files, I didn't enable ADB, so I cannot connect to reboot. Any advice? My last hope is that it will turn off at some point so I can charge it a little bit and see whether it will boot up again. Before I updated, I used the Android 9 version of this ROM and never had anything like this happening.

Edit: the background for the clock is completely black, there is really nothing else. It looks like the always on feature with only time and date visible.

Some news from the not working LED signalizing (1st recognized with my e-mail app): I recently installed the Signal messenger, it was triggering the LED to blink in blue color if a new message came in. This worked fine for days. Then I used the "mute" (GER: Stummschalten) feature and afterwards the LED was never again working (the sound is back). So it seems if once some "off / disable LED" setting was used by an app then this cannot be undone!

Is there some Android system feature where I can restore the "default LED settings"?

P.S. Sometimes I can see that my e-mail app is triggering the LED for a briefly light up.
