device encryption doesn't start

hello,
i have an i9500 and installed cm 12.1 (20151222) with twrp 2.8.7.0. i am using 3x3 gesture lock.
when i try to encrypt device, it shows the green encryption logo. (like zipper on his belly without the title and text saying encrypting, wait while ...)
the logo appears for a sencod, then the phone restarts with no error message or abnormality. just like i restarted the phone. so nothing happens.
- i tried leaving a 16KB+ space in the end of the data partition. but that didn't work.
- same result with any older cm 12.1 nightly releases and cm 11.
- makes no difference with a fresh install without gapps.
- i tried with built in root enabled/disabled and superSU installed.
- using pin or password instead of gesture lock does not work.
- when i try with the stock rom, it stucks at the encryption logo for hours, with no title and text. so, i pull the battery out, then i am having to wipe data.
thanks in advance for any solution offer.

As far as I know, data encryption on cm roms doesn't work.

[i9505] Cannot enter Recovery after Format Data

My i9505 was running stock KitKat from Samsung and I tried to install CM13 ROM.
So I used Odin to root the phone and installed TWRP 2.8.6.0. After that I flashed the CM13 ROM and the Gapps Nano.
I got as far as rebooting into CM13. But then the "Google Play Store has stopped working" message keeps popping up starting from the initial setup phase. I ignored the message and went on to setup the wifi but couldn't progress any further. The wifi was detected and connected but then it was stuck on the Checking Connection/Software Update step.
I tried to reflash the rom and gapps again to no avail. The third time to Format Data from TWRP before reflashing - still didn't make a difference.
What's worst is now I cannot even get into TWRP! Whenever I press Vol Up + Power + Home, it will show the small 'entering recovery' message momentarily on the top left corner but then it phone simply restarted again.
I tried re-flashing TWRP using Odin, but still didn't work.
I'm stuck now, cannot get into the OS nor the recovery. Any suggestion as to what to do?
Thank you.

Format Data from twrp sometime corrupts the file system and brick the phone. (It's happened to me once)
The best way is to flash official firmware via odin and start from there.

I see - I'll try re-flashing the official rom. Btw, would you recommend CWM recovery instead then? Honestly, I'm not very proficient with this whole thing. The reason why I formatted was because I still could see all of my old folders in the phone memory. So I thought Factory Reset didn't really clean up my old rom data.
What do I have to do if I want to start with a really clean slate with CM13 (after reflashing the official one first)?
Also, I still have the issue of CM13 setup being stuck at the Software Update step (right after Wifi setup). Any clue why that happened?
Thanks for taking the time to reply.

CWM is outdated. Your best bet is TWRP. Try version 3.0.0.
Factory reset doesn't wipe your internal memory, if that's what you mean, you will have to do it manually.
Also, I recommend wiping data, cache, dalvik and system partitions manually from the advanced wipe menu. Factory reset only wipes data and caches, not system.
Oh, and about that stuck at setup issue, just skip that step if possible, you can still change that crap later

If you are unable to set up the ROM, you could flash back to a completely stock ROM and start over.

OK, I'm back on stock Android now.
Before I try flashing CM13 again, I just need suggestions about these two issues I had from previous try:
Unfortunately, Google Play Store has stopped
I have searched for similar issues but can't quite pinpoint the cause. I used the correct GApps for my device and I also removed my SD card prior to installing.
Stuck on Check Connection/Software Update step
Last time I was stuck at this point and, responding to GDReaper, this step couldn't be skipped. The option was grayed out.

The sd card has nothing to do with it.
Sometimes gapps don't work on certain roms.
Just try another package.
If you use A-Gapps, the whole first time setup step will be skipped altogether. So that means that you won't run into the risk of getting stuck at that step again.
Or, after flashing the rom, you could use the recovery file manager to delete the setupwizard.apk after you flashed gapps. That should also prevent the initial setup process from initializing at first boot.

You probably used Opengapps. That also gives me a lot of errors.
Use Bankgs Gapps instead. They always work for me.

I used Open GApps, as was recommended in the CM13 post. So are you saying that my two issues were caused solely by the GApps? Because I thought me being stuck at Software Update was due to something else.

There are two files - one says Dynamic. But the file sizes are exactly the same. Is there any difference?

Not that I know. Just pick the one without Dynamic.

The initial setup process is related to gapps. And I don't recall there being any software update requests during the initial setup. It tells me to wait while it scans for network and WiFis, but I always skip those steps.
Open gapps sometimes work and sometimes they don't. It varies from day to day, since they are updated daily.
Just find a gapps package that works and stick to it until another version of android.

I just want to report back that my CM13 works perfectly with Banks GApps. Thanks to everyone who has helped!

Fingerprint scanner verification mode not working (?)

Hello guys !
I was rocking OOS 4.5.3 with TWRP and root all fine, and I tried some dualboot stuff that I saw here on XDA (plot twist, don't try it) and then I ran into issues
I managed to reinstall the rom fine, but at the reboot, my fingerprint sensor wasn't picking up my fingers
I found out that when I try to register a fingerprint, it works fine, untill the last step where it stop picking my finger (not even vibrates)
I also noticed that it's impossible to delete a stored fingerprint
Any ideas ?

On man I'm in totally the same situation with you! I tried that dualboot too and stuck in boot screen, so i flashed the original rom zip and managed to boot well but the fingerprint isn't working any more......:crying:waiting for solutions

Okay, now that I woke up I will try to do a data wipe, I'll tell you about it, please do tell me if you find something

I'm also unable to activate wifi

Sounds like a good question for the dual boot thread.
If I remember right from previous threads about dual boot on other devices is, you should delete your original fingerprint or set it up as no lock before doing all the stuff with dual boot. I might be wrong.

Well, can't see where it is listed in the instructions, but thankfully this issue is nothing a full wipe can't fix

It's not, it was just a user having that issue on a Nexus 6P. Reset should fix. Set it up without a lock on it, then you should be able to set up fingerprints for each rom.
Thinking about. It, that sounds like a lot of hassle if you just want to try out different roms quickly.

I did not do this dual boot but I ran into WiFi not activating (endless searching for a WiFi access point), but I was able to fix it. Your probably uninterested in how I got into the situation but I fixed it with a previous nandroid backup done with one of the earlier versions of TWRP. Here are the steps that recovered WiFi:
Using TWRP, advance wipe Dalvik & Cache
Restore from a nandroid backup (OOS v4.5.2 in this case) ONLY system & /System
Reboot into the system and ignore TWRP's no OS warning
Using TWRP, advance wipe Dalvik & Cache
Reboot back into TWRP recovery and flash the Full v4.5.5 OTA file (~1.6GB) AND flash root (e.g. SuperSU)
Clear Dalvik&Cache and reboot into the system
After I did that everything return back to normal including the WiFI issue. The fingerprint scanner is working normally and I never lost any data what so ever.

Fingerprint settings disappeared from settings

Hello, some days ago I was having some problems with my fingerprint sensor: it was recognizing gestures but i couldn't unlock my phone (the sensor was getting some sort of "false inputs").
I decided to remove my enrolled fingerprints and replace my fingerprint sensor with a new one and, from that moment, the fingerprint section disappeared from my settings.
The next steps I have done are:
- wiping the phone from stock recovery
- upgrading the firmware to L31C432B407 and wiping again from stock recovery
- wipe cache from stock recovery
- wipe cache and dalvik from EliteTWRP (after another dozen of wipes)
and nothing of these worked.
Is there a way to get my fingerprint sensor recognized?

Fingerprint always shows not recognised after lock remove

i'm on Stock Pie July 2020 update
and i just removed security lock and select swipe to unlock for taking TWRP Backup because after restoring TWRP backup pattern lock shows wrong pattern.
after taking backup i restart the phone and set pattern lock and add a fingerprint but when i put my finger on sensor it shows "Not Recognised" i tried 3-4 times also deleted "locksetting.db" from /data/system but nothing worked
is there any solution for it or just factory reset is the only option?

Reflash ROM through miflash tool. This might help

i flashed the full Stock Pie Firmware August 2020 but it didn't fix the problem. i can add fingerprints entries in Lockscreen settings but after that when i lock the phone with power key and try to unlock with fingerprint phone vibrates two times and shows not recognised.

I had the /firmware partition corrupted thanks to a TWRP blunder and it never recognised any fingerprints after that. I flashed this and it works again:
https://forum.xda-developers.com/mi-a1/themes/twrp-baseband-modem-april-stock-rom-t3777901/amp/
Not sure if it applies in your case though.

I had the same issue. After flashing persist.img from official fastboot Rom I was able to add fingerprints and they got recognized by the sensor.
I recommend to delete fingerprints and remove any Pic codes, patterns before flashing the .img file.

i'm using Lineage OS 17 now and Fingerprint works fine in LOS. the problem is just with stock rom.
i'm able to register fingerprints and swipe fingerprint sensor for notifications also works only unlocking not works always shows not recognised.
now i'm going to downgrade to Oreo then again upgrade to pie bcoz i got some touch problems after replacing touch screen maybe it also solve this issue
