[Q] Enryption fails on rooted S5 mini (G800F)? - Galaxy S5 Mini Q&A, Help & Troubleshooting

Hi there,
Just got a new S5 mini (SM-G800F) today. I've updated to latest Android version (4.4.2). I did not install any custom ROM. Build ID was KOT49H.G800FFXXU1ANJ1.
I've then rooted the phone successfully with CF-Auto-Root (http://autoroot.chainfire.eu/) and Odin. The closest file I found was KOT49H.G800FXXU1ANH2. ANJ1 to ANH2 looks like a "downgrade"... perhaps this is the issue? But read on..
I then started to install corporate access (Exchange account). Our corporation wants to have the device encrypted so I started to do that.
What basically happens is that the encryption droid symbol shows on the screen for about 20 minutes and after that the device reboots.
Yet, no encryption has happened! (is the anywhere a logfile I can look at for more info?)
I have a Samsung Galaxy S3 with 4.1.2, stock ROM as well and rooted with CF-Auto-Root. On that device the encryption process was more verbose and worked fine (although slowed down the phone considerably during normal usage).
So, does rooting the S5 mini with Autoroot break the encryption process? How can I encrypt the phone? Do I have to go back to pure unrooted stock, encrypt first and root later?
Thanks for any insights.
Dan

I still do not know why encryption would not work, but I found a workaround:
I reset the phone to the latest stock firmware with the help of Kies 3. I got G800FFXXU1ANG7. Obviously I lost all data, but that is ok since its a brand new phone.
Started the phone and configured WLAN to accept and install pending OTA upgrade. Just to get to the very latest release at the moment (G800FFXXU1ANJ2).
Encrypted device. I installed the corporate access tools which required the encryption...
Then I installed latest TWRP for my device with ODIN.
Last step was to install SuperSu with TWRP, using the zip file from chainfire.
Some remarks:
- I am not sure why encryption fails while the phone is rooted. Perhaps someone could explain to me?
- If I use CF-Autoroot after encryption of the device, the phone would go into a boot loop, i.e. not asking for the decrypt password and fall back to the boot logo. I thought that encryption would only touch /data. Most likely there is something that initiates decryption during boot, which is replaced by the CF-Autoroot image.
- OTA updates are not possible anymore after installing TWRP recovery (the phone complains that there are changes to the stock ROM). However, if I re-flashed with a stock recovery, OTA was not complaining anymore. If an update would actually work, I have not checked.
- If SuperSu is already installed however, even TWRP re-flashing with stock recovery would not make OTA work again. I would assume that the OTA update routine checks several components to decide if there is stock installed. Temporarily disabling SuperSu did not work, un-rooting through the SuperSu menu left me with SuperSu hanging for an hour until I switched the phone off. I also tried the OTA survival mode (I have SuperSU Pro) and it does not work either (in that try I left out step 2 above).
So for now I have a rooted S5 mini on Android 4.4.2 with encryption and I am happy. I did live without OTA with my S3 (which still is on 4.1.2) since I rooted it and frankly, I did not really miss 4.3...

Dan

If you change some files (like Recoery or rooting) OTA won't work anymore on any Samsung Rom...only pure Stock!

Thanks. That is what I thought.
1 - Encryption fails if the phone (S5 mini, 4.4.2) is rooted. Why? However, encrypting a rooted S3 (4.1.2 stock) did work fine. Was there anything changed with the newer Android versions?
2 - Do we know what the OTA process is checking to decide if it can go ahead or stall? SuperSu's OTA survival surely knows a bit more on that.. but unfortunately it still won't work..

Mahesh Senghani here please help me. Long time trying but not properly Root Access not properly configured or was not granted. Please sir how to fix this problem deeply request to you please solution easiest explain to me

Lost root and gapps wont work!

So my G5 Active was rooted and I had all of my mods and root apps etc. but then one day an at&t update appeared so since i had safestrap and multiple backups i wanted to see if supersu's survival mode worked... Well it did not work so the i went to reboot my phone and the safestrap boot screen didn't popup nor can i go into the safestrap recovery installer and boot into safestrap by clicking "boot into safestrap". So not the end of the world i don't desperately need root (even though i would like it back) but the playstore cant connect to the internet. I have tried re-installing and uninstalling updates. So this is really annoying and in my opinion a big problem but when i went to my workplace the next day and i connected to the Wifi at my workplace it worked again so then i realized that the only difference between my wifi and my offices wifi is that my offices wifi uses a proxy. So then i though it was the host file since i was having this problem right before i lost root and updated gapps and i had adaway. I cant access the host file without root and i tried using ADB push/pull and when i try to push it back it says read only interface so now I'm really stuck and help wold be much appreciated. Thank for taking the tome to read this.
I believe you have to ODIN back to before the update and then block the update, I haven't seen anyone say this is successful but what I understand it should be.

I did exactly that last night. I used ODIN to downgrade to Build ANE4 after the OTA update installed Build ANG3 on my Galaxy S5 Active. I had to do a factory reset afterward because my stock email app was repeatedly crashing. But towelroot worked and I'm back to normal with the OTA update frozen by Titanium Backup.

[Q] First Time Rooter, Gs6 SM-G920T, need help intresting problem cant find fix.

#1-"com.tmobile.pr.adapt (10001) has been granted superuser permissions for an interactive shell" pops up on my screen every 30 seconds on the bottom of my screen in a grey box.
#2- i also noticed that i can accept and recieve calls but i can not hear, nor can the other person hear me. if i use hangouts video call, skype, etc it works fine.
#3-i also tried to get rom manager to make a recovery and it says it needs to get CWD recovery to install a new software, the first thing we need to do is install a up to date version, we will begin that process now... etc.. then it says to get started you must first sset up a custom recovery, it gives two options a samsung galaxy s3 on metro pcs or a samsung previal 2 on boost mobile, or device not listed, when i click that it says "SM-G920T does not have an officially supported CWDR yet. Have you installed a CWD based recovery manually?" so im not sure what to do from there, or if i even need that. i have been a iphone user since day one went to android after reading up a lot on it, although rooting is quite different than jailbreaking it seems, i am incredibly excited to get started if i can get past these little problems and get started and figure everything out. ANY advice, or anwsers to these problems would be Greatly appreciated! thanks!
Also i went to dev options in settings and noticed the "OEM unlocking- allow the bootloader to be unlocker" was turned off, i dont know if this is necessary to root if i did something wrong by not turning it on or what, or if it may fix any problems above if i turn it on now. thanks!
I have a samsung Galaxy S6 (SM_G920T) . i Rooted and did not trip Knox, Although i did just remember that my fingerprint sensor is not working either.
Thank you guys so much this si a incredible forum i have spent hours and hours reading and researching before making this post i appreciate it so much!
#1 Freeze that ****. Use some root tool to freeze that T-mobile apk, seems u gave it root permissions at some point. I believe there are a lot of apps that you will want to do the same.
#2 ? No idea. Stock rom/kernel?
#3 What is this I don't even. Don't do that. Go to TWRP's official web, get your zeroflte (SM-GT920T) twrp and flash it via ODIN, or else get the recovery.img and use flashify. All that assuming you want a custom recovery.
You will need to unlock the bootloader if you are on 5.1.1. I believe locked will prevent changes or wiping anything on the OS partitions, even recovery (can someone confirm?)
I believe jailbraking and rooting should be pretty much similar, if not the same, as both target to grant the user root access to do whatever he pleases on the OS.
Welcome to android btw.
How did you root? Sounds like you used the modified sboot which causes no sounds in calls and nonfunctional fingerprint scanner. If so, flash back to stock and use a different rooting method. The rest, pretty much what the above poster stated
Root
I rooted using the version that I found the only one that works it seemed like, went to Odin put my phone In download mode and then put the boot loader download in BL and the. Put a something unikernel.sbin I believe, whatever the guide said also then it was done. I thought you couldn't use the twrp or custom recovery etc on tmobile one yet but I just read a thing about xtrestolite odex pure v2 which says it's for 5.1.1 and my model of phone but in the guide it says to root using CF auto root and a link there to it but the link doesn't have my phone on the list that the guide that clearly is my phone says to use I don't know if I'm missing something but I want to use it I understand most of it but I don't know if I need to unropt first and re root then use Odin and flash twrp that's supported on my phone then use that to recover the rom. Etc. The kernel that says is used in the guide is the same one I downloaded so do I need to remove it all then let it do that or?
Sorry if this didn't make sense I'm halfway there between confused and understood I have spent the last 10 hours reading and trying to figure this out though lol. Thanks guys!
Also
Sorry for adding more but also how do I flash back to stock? Search for the download to the stock image of my phone? Also I could only find one way of rooting everything else said it wasn't working yet or am I missing a big portion of something here?
Just flash the 5.1.1 firmware to return to stock. To root, flash unikernel with Odin. The other method you used was to not trip knox, but as you experienced has side effects. I had to Odin back to 5.1.1 myself. Can't have those issues
thanks!
so how do i flash back to 5.1.1? find the ling to completely stock 5.1.1 and flash through odin in the same spot and same way i flashed the kernel to root? also.. i rooted with " s6_UniKernel_v2-0003-ODIN.tar" is that not the one you were talking about?

Yes, flashing to 5.1.1 works exactly like that. You need to get the version for your model (very important on this one) and then simply place that file in the AP field of ODIN while the device is in recovery mode. It is normal for ODIN to freeze for 2 minutes while verifying. Make sure to use a MD5 checker tool on the firmware before flashing.
Rooting has historically required more technical savvy and balls than jailbreaking, but PingPong made rooting the S6 brain-dead simple. CF-Auto root is still pretty painless, but you must make sure you have the right zip for your device.
Anyhoo, the quickest & easiest way to restore phone calls & fingerprint scan is to use Odin to get back to bone stock.
Next, use PingPong to root. After rooting, "com.tmobile.pr.adapt" will ask for root access. That is T-Mobile's "phone home" app and sends info about your device (probably including root status). Deny it root access and make sure you check "Remember my choice", and it won't bother you again. You will not lose any functionality by denying it root, so terminate that crap.
Don't bother with rom manager. CWM is archaic. If you want a custom recovery, use TWRP. You can install TWRP either using Odin or TWRP Manager app (it's free).
Good luck and have fun with your S6

Are you still rooted? If so, and if you are experiencing the call audio issue, go flash AOU's kernel. He has made a kernel for the tmo s6. that should eliminate your call audio issue. The finger print scanner is the only issue with flashing his kernel. Also, I rooted with the modded sboot, his TWRP and kernel, and I didn't trip knox

January ota update help needed

OK I got the notification to update today it's MMB29S, I am on K. I am rooted but stock, unlocked using systemless root for root. I've always been rooted and expected it to fail and have to install manually but this time because I'm not rooted like the old way. So i downloaded and went to install to my surprise dead Android with the triangle didn't show but it went to custom recovery screen twrp. I just hit restart because I've never not had a fail and never seen it do this before. Well when it restarted I was not updated and still on K. I also for the life of me can't get it to redo the ota. Tried to clear system service in apps and recheck but nothing.
So my question is since I'm new to systemless root what should I have done when it went to custom recovery? So that way if I can get it to pop up again I can be updated. Thank you in advance for any help and it would be awesome if possible to update this way without having to manually do it.
My best guess, based on what Chainfire replied to me when I asked about OTA, is that because you're somehow rooted the OTA will refuse to install. He said that using the "unroot" function in v2.63 (and I suppose in subsequent versions) he was able to apply the OTA and then just had to re-root.
As to the OTA, I read in the long-distant past that once it's been provided to your device you sort of go to the back of the queue, and even pressing the "check for system update" button has no effect. One day your turn will come again. When it happens, before you press the "install now" button, use the unroot function, reboot, and give it another go.
And I would really appreciate it if you could report back on the success or failure, just so we all know - thanks...
And before I close... your alternative is just to download the full ROM from Google, unzip everything in sight (including the zip within the zip), copy system.img to a convenient folder, and use Fastboot to flash system. After that you'll need to re-root (simple flash) and when you reboot everything will be as it was, apart from the version and security update date. I did it myself to MMB29S a week or so ago.
But my lawyer advises me to advise you to take a full backup first and store it off your device before you do anything to your device - just in case, you know?
I will definitely reply if I get the update again in a few days. If it doesn't I'll probably do it manually. I was just really surprised I hadn't gotten the error, just so used to it. Thank you for the info though.
Correct me if I'm wrong, but to install an OTA don't you need to be completely stock, including recovery?
If I'm not mistaken but since 4.3 (I'm probably wrong) if your rooted (before systemless root) when you try to the ota you will always get the dead Android because rooting changes the system files causing the update when it does is checks to think your system is corrupt.
Also it was really bad when people tried going from 5.x.x to 6.x even doing it manually some of us got bootlooped or when starting the phone up after updating manually saying system is corrupt but still starting up fine. Leaving like me having to completely clear out everything and installing the factory image just to not be corrupt and able to use Android pay.
Systemless root though I've not had a single problem and still able to use AP. And is also the first time in years I've gotten as far as I did with the OTA.

These small ota's can be done with boot modifications because they don't include any boot.img changes and if they do then they just blanket overwrite what's already there. The only part that is checked is /system. However TWRP won't ever install an ota update for compatibility reasons. Even if you reflash the stock recovery then you'll fail the ota because when you installed TWRP it protected itself (by modifying /system) from being overwritten by the stock recovery which is what unmodded stock android will always do on boot by default. And there are 2 things the ota verification looks for when updating: 1. It looks for whether /system has been ever mounted as Read/Write. 2. It hash checks the /system, if it finds any mismatch it fails. As for the update not showing up again, the ota checker hides the update after a failure to stop from flooding the download server. If you want to extract the update zip you can look in /cache for the zip. But since you don't have an unmodded /system you might as well just download the newest factory image and manually flash the system.img
You can use Wug NRT, unroot with MMB29S provided in the NRT , then root.

SM-N920P Really need help with deep sleep battery life and TWRP! Will donate for help

Hey Guys,
Long story short, I had my Sprint Note 5 rooted a while ago! due to some apps screwing me over and not allowing to use them due to being rooted I unrooted (via supersu)
Realized ever since I rooted my battery was totally crap and figured after I unroot it would help (it didn't) read about how it trips the Knox and it affects the deep sleep of the phone (thus **** battery life)
I read on here to just load a kernel in order to fix the deep sleep issue. I've rooted and loaded kernels before on other phones (no issues everrrrr).
When I looked up the TWRP version to use and flash via Odin it said successful. Phone restarted and it never came back up again. I downloaded literally all of the TWRP versions they had on their site, flashed all of them via odin and none of them would get me out of the boot loop. I got completely screwed and had to load a stock firmware from that sam site to get my phone working again. Everything was completely lost on my phone. pics that were never backed up
Due to that, I have been totally hesitant to try this again as that was the only way to fix my phone. I am willing to try again but really want to go into this prepared and have it be a smooth process ( I already backed up ALL of my files on my computer) I don't really care for TWRP or Kernels but I just want to fix the stupid deep sleep issue. I read somewhere on here that people having bootloops from twrp on note 5s was due to not being rooted first? I've also seen (as I did this almost 8 months ago) there are new TWRP versions since then, but afraid to even do those.
Is there a solution I can do to just fix the damn deep sleep issue? phone literally last 2-3 hours idle. Willing to donate via paypal to someone to help walk through it. This is a sprint variant note 5
thanks in advance
TWRP for your phone is here :
https://dl.twrp.me/nobleltespr/
When flashing in Odin are you using the AP slot to load twrp?
You can keep the rom stock and root with magisk or go custom. Looks like the sprint page for the note 5 is still relatively active.
Use Smart Switch to restore your phone, even update it to the latest build (DQG2). This will reinstall EVERYTHING you have modded. Maybe a 4 file firmware could be used via Odin. Now download the newest TWRP from the link phuhcue gave you. Install it via Odin. Put the recovery in the AP Slot. To root, you can use Magisk or SuperSU. I use Magisk because it can pass Google's Safety Net, so you can still watch Netflix or use apps like Pokemon GO or Snapchat.
After Odin installs the recovery it will reboot, this is where you need to be very fast and enter recovery mode and install 2 files:
Latest Magisk: https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445
IMMEDIATELY after installing Magisk this file might be necessary: samsung-antiroot-removal-4.1.zip (I tried not to use it but my phone bootloops) https://build.nethunter.com/samsung-tools/samsung-antiroot-removal/ After installing both .zips you can reboot and voila! you have root + custom recovery.
This is the method I've using since our Sprint phones got the Nougat update. The tutorial can be found here: http://galaxynote5root.com/galaxy-n...galaxy-note-5-on-android-7-0-nougat-w-magisk/
Magisk is the shiznit yo! I'VE NEVER HAD DEEP SLEEP ISSUES, RANDOM REBOOTS OR OTHER FAILURES ON MY SM-N920P ALWAYS RUNNING THE LATEST NOUGAT BUILD. Rooted Marshmallow was buggy and laggy as hell, so I never rooted my phone until Nougat came out. The Sprint model is NOT affected by the tripped KNOX.

Question Will root persist after an OTA update?

I've wondered this ever since my Tab S8+ reported it's device status as official despite me having flashed the tablet with magisk-patched firmware and asked me to update. This same exact scenario has happened with my rooted Tab S7+. However, I rooted that by flashing Magisk in TWRP rather than flashing patched firmware with Odin. I don't think anyone has tried applying an OTA update on their rooted Tab S8 device since the latest firmware isn't available yet, and could result in needed to flash patched firmware again. Then again, most rooted device will have their devices report as custom instead of official, so that may be why.
I'm willing to try this out on my Tab S7+ first as that device has TWRP, and I can easily restore my device to a rooted state afterwards. Since both tablets are relatively similar, I'll assume that if root persists after updating in the Tab S7+ then it should be safe to do so on the S8+ I'm curious of doing this solely for stability and performance updates in combination with everything root access grants.
With any part of the firmware patched, OTAs won't work - they'll fail. You could also wind up with a brick - most likely one you can recover from but I wouldn't bet either way on that. As always, have everything backed up in case the worst happens.
Since I still won't get my Tab S8 Ultra for another 10 days (unless they delay again), I haven't paid too close attention to the rooting instructions specific to this, and have only made note of them, however, the basic rule still applies - if any part of the firmware has been modified from stock, then OTAs will recognize that it's been modified and fail to apply - or as I said, it could possibly try to apply what it can but you could wind up with a mix and match of different firmware versions due to the OTA failing eventually, which would need some manual work to recover from - or very worst, you might need to start over from scratch and lose everything.
When I'm on any rooted device, I go into Developer options and disable Automatic system updates. It's still possible you could get an update prompt if you manually check for an update, but it's not advised to use OTAs when rooted.
I've always been a practitioner on all devices of flashing the full new firmware updates and re-rooting, however, I know that at least with devices with dual system partitions like Google Pixels (as far as I'm aware, Samsung still hasn't adopted dual partitions yet), there have been ways to apply Magisk to a manually sideloaded OTA, although I've observed other users who do this and something inevitably goes wrong with the process from time to time.
Not that full firmware flashes are immune to things going wrong.
Edit: If you try an OTA on yours, by all means, let us know what happens.
Edit 2: Adding TWRP to the mix may, or may not, affect the viability of applying OTAs. I've hardly used TWRP on any device in the last five years, so I'm not sure if it's smart about some things and can take root into account, but since TWRP doesn't exist on the Tab S8 (I don't have any older Tab), it won't matter for me.

Just attempted to OTA update on my Tab S7+ after making a backup, and it failed. When it rebooted to start applying the update, it booted into recovery to start flashing, but since I have TWRP installed, it booted to that instead, went straight to the main menu, and didn't apply the update. It's extremely ironic; my tablet says it's running unauthorized software and will no longer receive firmware updates, but it also says my device status is official and allows me to download and install updates if I check for them (it'll even mention there's an update available without having automatic download installed).
I rebooted to system, it said they the update failed, and prompted me to download the update again and try again. I can't tell if anything got affected since it seems like because the update failed, nothing got applied or changed. This makes me slightly less willing to try and OTA update on the Tab S8+. However, since the stock recovery is still in place (no TWRP yet), the update process would probably go a long smoother. Not to mention, if something was to go wrong, and I needed to flash patched firmware again, I could just flash HOME_CSC instead of the regular CSC so I can keep my data. There's no guarantee that will work, as a failed update could require my system to prompt me to factory data reset anyway, but it's definitely an option that's available.
I'll backup whatever I can before attempting this, and I'll post the results later.
Answer would be no, doing OTA requires bootloader to be locked. But since you rooted, then you have unlocked the bootloader. So if your tab s8+ has locked bootloader then OTA will pass without a problem.

Really? I thought having an unlocked bootloader would be a non-issue since you can flashing official and unofficial firmware with an unlocked bootloader. Not to mention that the recovery has remained unaffected, and stock recovery needs to be accessed to apply the update.

when unlocking bootloader you have to manually flash the stock firmware. Since OTA becomes unavailable when bootloader is unlocked. So if root is done in for example android 12 and you get a monthly patch then it will revoke the root since root usually modifies the OS files and gives you the root access sort off and flashing a update will write over those files and your root privileges will be removed.

Huh. I thought that doing an OTA update wouldn't remove anything that was already a part of the system and would just just update whatever needed to be updated and called it a day. With the method of patching the firmware and flashing it, I assume root would just be a regular part of the system, and an OTA update wouldn't affect it. Odd...

That is because your normal access is only admin not root. So it has almost full rights, but when you add root access it is mostlikely a modification that you have to do, either by a command or flashing a file. But updating the OS will revoke the root since method you used becomes unavailable for next update which is why it can reset your changes backwards so your root privileges becomes lost and your access is back to default as before. But I wouldn't touch bootloader since doing that also bricks KNOX so features for KNOX will become permanently disabled since it requires a working Knox chip to work, but since KNOX chip fuse becomes blown when bootloader is unlocked then feature like Samsung pass, samsung secret folder and such will no longer work.

Turns out you were absolutely correct. I downloaded and attempted to install the update, it booted into the stock recovery and got to 25% before erroring out. It booted back into Android and said that the update failed. Thankfully, nothing ended up getting removed or corrupted, and I still have root access. Guess I gotta stick to finding the latest firmware and patching it. ¯\_(ツ)_/¯
