[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CWM is outdated.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?

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!

Nexus 6p not booting (running custom ROM)

A little bit of background.
Prior to this problem I was running dirty unicorns and elementalx kernel. Given that lately I had some freezing issues I decided that iro was time to update my ROM. Being the first time that I manually update a ROM and not having found anything online I thought (dumb decision) that all I had to do was to flash the most recent version. After I did that the phone did an app optimization (idk if that's how it's called, basically it optimised all the apps for the new version of the ROM) . After that the phone wasn't booting up, the dirty unicorns loading screen was running for half an hour and nothing happened so I restated the phone. When it asked for my sequence a message popped up "it looks like your vendor image is obsolete". The phone still wasn't booting up so I decided to restart once again and install the latest vendor image. After that the phone wasn't booting up so I decided to do a backup with twrp (version 3.0.0.0) and do a factory reset.
Plot twist the twrp decryption sequence (that worked 10 minutes before) now wasn't working so I had no way to access any of the phone's files.
Basically the phone won't turn on and I have no way of accessing it's files
I'd try a factory reset but there are some photos and whatsapp messages that are important to me and I'd rather not lose them.
Any tips?
Apologies for my terrible English

The best thing to do is this guide. http://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928/page384. Just go full stock without formating the internal. Flash twrp and see if you can get your photos. Next time back your photos up with Google photos if available in your area. Good luck

To update a ROM all you usually need to do is flash the newer version, but you also need to flash the newer vendor.img of the updated ROM is based on a newer Google build. Failure to do this is what caused the "it looks like your vendor image is obsolete" message to appear. I'm guessing you know this though as you went on to flash it later.
Not sure what happened with TWRP but you've done something else wrong at some point. Best idea (as pointed out above) is to flash the factory images. You can try it without formatting userdata in order to retrieve whatever it is that's important on your storage, but once you've retrieved whatever you need (if you even can) you'll need to format it because you really need to start fresh.

When WiFi is turned off I get 'Unfortunately System UI has stopped'

This is on two standard Galaxy S5's, with standard ROM, etc - not rooted, or anything else.
Every time I turn off WiFi, or enable Mobile Hotspot, I get 'Unfortunately System UI has stopped'.
To fix I have to Power off/on the phone.
(Turning on WiFi is no problem, just turning it off.)
I have gone into 'Safe Mode', and same issue, so it looks to not be a bad App.
I have also uninstalled 'Google' updates, and again no change...
Any thoughts?

All of a sudden my S5 showed the exact same error message for no aparent reason... I didn't do anything, and now I can't use my phone at all because of that bug. It happens on every boot so I can't even unlock my phone. Tried reinstalling everything, ROM, recovery, kernel, with/without root = still same, what just happened here??
EDIT: Same thing if I'm in Safe Mode -_-

Seeing noone knows a solution here's what I did yesterday.
1. Backed up all my stuff from internal storage to the sd card
2. Did factory reset in TWRP recovery
3. Flashed completely stock official firmware from Samsung
4. Waited for it to boot up and try to restore some of my settings (it restored all folders on their places, made same amount of home screens as I had before the reinstall and downloaded all of my previously installed apps from the Play Store, ofcourse without the cracked ones, and it also restored most apps' data as well so it's not as bad as you may think to factory reset and reinstall everything)
5. Started rooting, flashing TWRP again, installing Dolby Audio, Xposed and everything I had before, took me one full day to set it up as it was before.
Now when I set it up I always make a nandroid backup from when things are working fine, in case it goes crazy for no reason again... Good luck!

when the wifi radio is acting weird, a dirty flash of your current ROM susually fixes is as its probably a radio issue. Id do that before doing anything drastic like the boot-n-nuke Odin flash and starting from scratch (which will fix that issue)

I don't think I have a ROM issue, as I have two S5's, and both have the same issue... and both are standard ROMs.
I will do a factory re-set on one at some point, but this looks to be a 'simpler' issue.
I have tried a full Cache delete, as well as other 'clean' processes.
Nothing works.

I tried to re-flash my stock ROM as @youdoofus said but still had that annoying popup. Try everything you can think of, if all else fails, reset.

well, you can wipe cache, and dalvik 3x each (not kidding about the 3x each), then dirty flash the rom, pray to the gods of android, reboot. If failure occurs, its Odin Nuke time unless you want to try to flash an individual radio file by itself (not recommended)

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.

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.

h910 crashing, even after factory reset

UPDATE: Please read the next post.
A while back, I rooted my v20 with magisk using this method and everything worked fine for a few months, except for a few issues that reflashing the system would fix. Last night, SystemUI kept crashing (the status bar and the buttons would disappear). After a while, the phone crashed, and then it completely refused to boot. It would very rarely get to the lock screen, but it usually crashes soon after I unlock it. I tried everything I know of that could fix it, such as restoring the boot partition and reflashing magisk, reflashing the system partition, and wiping the cache and dalvik/ART cache. I eventually gave up with this and just reset it through the wipe menu in TWRP. I was able to get the phone to work for about a day without any issues, and then the same thing started happening again. It would take a really long time to boot and the system would crash. I tried using that ~1 minute it gives me before crashing to enable core mode in magisk to prevent any modules from loading, but that didn't do anything. I am really confused as to why this would happen considering that I reset the boot and system partitions multiple times in this process, and eventually did a full reset. It should be like a brand new phone. I really don't know what could possibly be the issue. Any help would be greatly appreciated.

Update: It turns out that Magisk Core Only Mode did not properly apply because of yet another crash. I cleared my cache once more, which gave me enough time to properly apply it, and now my phone is staying on and not crashing. But this still is concerning to me. I was able to run Magisk modules perfectly fine in the past, including after the most recent Magisk zip update, so why is it that I can no longer run modules, and that this issue persists after a factory reset? It can't be an update, because, as I stated, I was able to run modules just fine for at least a week before these issues occurred. Please correct me if I'm wrong, but this makes absolutely no sense and I want to be able to run modules again. I even deleted the modules through TWRP but the only thing that seems to fix this issue is completely disabling all other features via Magisk Core Only Mode.

Update 2: A Magisk update came out recently and I tried updating to that to see if it would fix the issue. This only brought back the original crashes. I tried using the Magisk uninstaller zip (because I found that simply reflashing Magisk isn't enough, there are other files which magisk uses to store data.) After doing this and reflashing Magisk, it worked for a little bit, but, me being me and wanting busybox installed, I managed to bring back the crashes. After that, uninstalling and flashing magisk would work, but only until a reboot. I am at a complete loss. I am currently backing up my internal storage (manually since TWRP doesn't) and I will try a full /data format.
Ok, it has been a few days since I wrote the previous section but I decided not to post it because if the /data format worked, I didn't want to have bumped it for no reason. At first, it worked, and I decided to leave it like that without rebooting it for a few days or messing with Magisk, and my phone worked perfectly. I had to restart my phone because Google photos was acting up, and it started crashing again. I am genuinely confused. I completely formatted my phone and reflashed Magisk several times, and it is still crashing. I just reset my phone again because I attempted to just restore a stock boot backup from before I installed Magisk, which made my phone completely unbootable. I pulled the battery and found that it tried re-encrypting the phone (AFAIK, TWRP doesn't support encrypted data on the v20, which really sucks) so I had to wipe it and flash Magisk so it wouldn't re-encrypt it. I will try to do this again, but I don't want to not be able to restart my phone (which is so far the only thing that's working for me). This time, not even uninstalling and re-flashing Magisk worked this time, as it has all of my previous attempts. I had to completely reset it. Again. I really need this issue fixed. I probably already said this, but I would greatly appriciate any possible help I could get. I really want my phone back.
Ok I forgot to include some basic information about my phone.
Model number: LG-H910
Android version: 7.0
Android security patch level: April 1, 2017
Kernel version: 3.18.55
Build number: NRD90M
Software version: H91010m
According to Kernel Auditor:
Kernel: Linux version 3.18.55-Werewolf-2.0-Basilisk ([email protected]) (gcc version 6.3.1 20170430 (GCC) ) #1 SMP PREEMPT Sat Jun 24 00:56:07 CDT 2017

Bump/Update: This is a small one, but, despite not restarting my phone, Magisk is showing an error "Magisk is not installed". Root access also disappeared. I don't know how much longer I can keep it on without having to restart it due to random issues like these that usually fix themselves with a reboot. I would appreciate any help.

Seems like your phone is all sorts of wacked out. I noticed from the specs your using the werewolf kernel. I had all sorts of performance issues as well as random reboots using that kernel. Since you're losing root and the system is overall unstable I recommend wiping clean and starting over. Wipe system, data, cache, and dalvik in twrp and flash the full stock 10r zip by runningnak3d. It will put you on the latest security patch with the newest firmware available. I recommend installing askerm2000 1.4 kernel as it is very stable and works well on the h910. Flash magisk last (latest 15.3 works great for me) and reboot. Hopefully will solve your problems. The 10r zip for the h910 plus askermk2000 kernel and magisk has served me well for a while now.

Thank you. Before I do this, I have a few questions.
1. How do I disable force encrypt with Magisk? I remember when I flashed Magisk 14.0, that managed to disable force encrypt, but any other version of Magisk wouldn't do that when installing fresh (updates kept this setting). AFAIK TWRP is unusable on the v20 for things such as backups, file browser, etc because it isn't compatible with the encryption algorithm used by the v20. How would I turn off force encrypt with the latest Magisk zip
2. Should I do a full format data (where you have to actually type "yes" to confirm it) or just wipe those partitions using advanced wipe?
3. Will the askerm2000 kernel hide modified boot, unlocked bootloader, etc from safetynet just as Werewolf kernel did, and will it get rid of the static boot issue?
4. Will this increment ARB? If anything goes wrong, I want to be able to roll back.
5. If it was working perfectly fine before, what suddenly made everything come crashing down, even after multiple wipes? This is not as important as the other ones, I am just curious.
Sorry if these questions seem over excessive and/or obvious. Doing stuff like this tends to make me a bit nervous and I want to think of everything I can that might affect the outcome.

Twrp can properly decrypt the v20. Twrp backup and restore works just fine for me. Never had an issue with this. You format data and then type yes. Wipes the data partition but this is only needed once. Decrypts the device and twrp can then do it's thing. Encryption problems stem from booting into system with a stock boot image that has force encryption enabled without flashing magisk or supersu. They modify the kernel to prevent the device from rencrypting. Latest magisk 15.3 has zero issues keeping the phone decrypted. The modified boot warning has nothing to do with the kernel. This is caused by the debug bootloader used to achieve root on the US carrier v20's. Nothing can be done to change that. ARB has not been incremented on the h910 so that isn't an issue currently. Potentially in the future, but not right now. The problems you're having could stem from a multitude of issues. Could be modifications you made, bad flashes, etc. If you're having issues with encryption and stuff sounds like magisk wasn't functioning properly at the end. I've been rooted since last January and haven't experienced anything like that before so I'm not sure

I've been rooted since last January and haven't experienced anything like that before so I'm not sure

Ok, I cannot possibly thank you enough for this. After this started happening, I seriously thought my phone was at the end of its life. If this were to happen, I wouldn't be able to get a new phone anytime soon. Not only did it fix the crashes (I only restarted it once, I'm not going to try to intentionally make it crash), It ALSO managed to fix my FM radio and (I think) the Google Assistant Voice Match unlock thing, both of which I never even thought I would be able to get back. Let's just hope that it stays this way. I have one last question. Would you say it's safe to download and install Magisk modules now?

Yes. I use a few modules myself without an issue. If you're unsure of the stability of a module, you can always take a nandroid backup in twrp prior to installation. If things are stable, and then you flash something and the phone freaks out, it's most definitely the mod you have flashed causing problems. Some modules make changes to the system partition that have the potential to problems. But I haven't had a module cause my device to bootloop or reencrypt. So I think you're good to go. Glad you're phone is up and running as it should. Very strange that it was in such a bad way, but crap happens. I have had zero issues with this setup (10r + 1.4 askermk kernel + magisk 15.3).

I have the stock firmware on the H990 version, I end up on the Crash LK screen error. I can access TWRP, how can I restore access to my device without losing data? Thanks.
