Help me downgrade please - Galaxy S6 Q&A, Help & Troubleshooting

I was just wondering if anyone knows how to downgrade from a 6.0.1 custom rom to a 5.1.1 custom rom.
I have no access to a computer so everything will have to be done via flashify or TWRP.
Any links to things like boot loaders would be much appreciated
Thanks ?
EDIT: if anyone could just help my battery last longer that would be great too im on amasidi v3.2 and hacker kernel unclocked and undervolted and greenify and amplify and it still drinks the battery

how you solved?

Deep Sleep issues after rooting with PingPong

Hi all guys!
New phone, first post in the new community!
I just grabbed a SGS6 on 5.0.2 stock Samsung rom which i rooted with PingPong root method to avoid tripping my knox.
Everything works flawlessly but the phone seems to be unable to enter in deep sleep mode. I have already cleaned my cache from stock recovery without success.
Any clues? I have made some research but it seems that i cant manage to find a solution for this particular situation. Thanks yall for the help as always!

Unroot without losing data and custom kernel?

Hi at risk of been repetitive im going to ask something that might have already been answerd on the the forum but given the specific caracteristic of my device i hope someone can answer anyway
Thing is i have a rooted nexus five (6.0.1 Stock ROM) with Ek kernel and I was wondering if i could unroot through the SuperSu menu without losing any data and keeping the custom kernel just so i could install the lastest OTA update and encrypt my phone. It seems i would have to flash stock boot.img to encrypt but i dont know if this is enough to update and encrypt without losing custom kernel and data in the process as I pretend to inmediatly root after doing these two things. Also if anyone can recommend a good alternate kernel for perfomance/battery life just in case there is a better option although i have to say im very happy with this one.
Hope this particular question hasnt being answerd before and any help would be aprecciated
Thank you very much

[Completed] Firmware for my SM-N705 Samsung Note 3 Neo

Hey there everyone, i was running Android 4.3 on my Note 3 Neo, and i upgraded to Lollipop 5.1.1 via Odin. The Firmware that i downloaded and installed was Stock Firmware N7505POUDOK2, the problem is that i cant keep root now, my phone was previously rooted on 4.3 and worked properly. Now, if i root my phone with Kingroot, it will get done and root will work, but randomly after a few minutes my phone will restart and when it does my root access is gone again.
Can someone tell me what is wrong? How do i fix this problem? Also, there were two 5.1.1 firmwares for my phone, N7505POUDOK2 (which i installed) and N7505POUDPA1. Did i flash the wrong firmware or something? Should i have installed the other one? Also, im not sure if it is related to this problem, but ever since i flashed 5.1.1, in google play store when i try to install apps, they sometimes don't download and take a very long time to install or somehow get cancelled.
Can someone please help me?
Thanks in advance.

Pretty sure this is a selinux issue with touchwizz lollipop. If you install a permissive kernel (any custom kernel) for your device then you should be fine
Good Luck

Back on Stock Nougat and very happy

After several weeks of battling terrible battery drain, lag and sluggish performance I am back on Stock Nougat, build number NPJS25.93-14-8. With moderate use, my battery is now averaging less than 2% per hour ( < 1% while sleeping), where on the custom ROM of choice it was running over 5% per hour, even while sleeping. I tried every trick and tweak I could find and Better Battery Stats didn't show anything that could account for the high drain. I even tried a different ROM to no avail. So I threw in the towel, returned to stock, and did the latest OTA updates. I am now running rooted with ElementalX kernel 1.04 and I couldn't be more pleases with the overall performance and battery life.
I am sure it was something I missed but I got tired of spending hours trying to get back to the original performance and battery life the custom ROM had several weeks ago. Sometimes you just gotta do what you gotta do.
While ota updates.......i brought to twrp only.... instead of installing latest security update.......... manually tried to install update...bt i can't..... gets an error... didn't u faced such problems

None of STOCK ROM or OTA updates can be flashed/updated by TWRP, you need to be on stock recovery as well everything stock (unmodified system, boot and all).
I faced this problem too, but I fixed mostly of the battery drain tweaking the kernel with the ElementalX app to ~0,80/h. I had to set the little cores working like big cores do, because all little cores and one big were in use always; and applied LightingBlade profile.

In order to use the OTA path you have to be on stock recovery, boot and kernel, not on TWRP. Otherwise you get the error that you experienced.

I went that path but it didn't seem to help much. Besides, I am happy with this stock setup. It is much better than when I was on Marshmallow stock and went over to custom ROMs. I can do anything I want to do and install any app I desire to use. Good performance, great battery life, and customizable as much as I want. No need to be on custom.

Before you can root stock Nougat you must first unlock you bootloader, install TWRP then flash Elemental X kernel 1.04 from TWRP.

Instead of asking questions that have been answered numerous times (ad nauseam) you should try reading through the forums. I realize you are a raw noob, but if you wanted to learn Calculus, would you ask a bunch of questions without doing any reading and studying? It's no different when you are modifying your smart phone.
Here is a link to a thread that will guide you to rooting stock Nougat. It works for all versions of stock Nougat.
https://forum.xda-developers.com/mo...de-root-moto-g4-plus-supersu-android-t3587918
But don't do anything until you have read through the procedures and fully understand. Above all, make a backup of your system from TWRP before you do anything else.

Very true.
Also try LightningBlade tunables(v 1.2.3 ; the newer version does not work that well for me..).
Stock rom provides the best balance between Performance and Battery life.

If you're rooting on stock Nougat, you must have a custom kernel flashed (or used the temporary dm-verity disabler on the stock kernel) before you root. Else, without the mentioned modifications, you'll trip the anti-rooting protection built into the stock kernel, and you'll have bootloops unless you reflash your stock ROM as you experienced.
Easiest way, as per the guide is to:
Flash/boot TWRP.
Backup.
Flash ElementalX or vegito (any custom kernel will do, as these kernels do not have the anti-rooting protection).
Reboot to test.
Boot back to TWRP
Flash SuperSU v2.79 or newer, or magisk 13 or newer
Reboot.
You should be rooted, on stock, and if you've flashed magisk, Safetynet should be working It's working well on NPJS25.93-14-8 and it's stable. Granted, a few apps now seem to detect root/magisk (and fail to download/update from the Play Store, with an error 0), but nothing that a sideload from a legitimate source wouldn't solve...

Hi, sorry for ask, do you know where can i find the temporary dm-verity disabler?
I tried with a script named "no-verity-opt-encrypt-5.1" (this works for the G5 Plus 'Potter') but i haven't had any success. Even i unpacked the stock boot.img and i tried to manually patch it, but i failed here too.
Honestly i would like to test the stock kernel, because i never used it, i am always attached to flashing EX to get root access. Thank you in advance.

I don't know if this will still work on later builds than the November/December 2016 builds, but here's the kernel with dm-verity disabled: https://forum.xda-developers.com/mo...t-how-to-root-n-firmware-npj25-93-11-t3532556 Seems to cause bootloops though on the later builds however
Strictly speaking, I misspoke - it's not really a dm-verity disabler, more a stock kernel with dm-verity disabled. I think EX kernel is still the more stable and more reliable option. It would be nice to be able to root the stock kernel though...

Oh, i see, thanks for your response. I'll look into it to see how he did to by-pass the dm verity, and try to modify the last boot.img that we have.
I mentioned earlier in this thread about getting Error 0 whilst updating apps in Google Play. As it turns out, thanks to this tip here https://forum.xda-developers.com/showpost.php?p=73552496&postcount=57 it appears to be an error with permissions on the /data/media partition.
I managed to fix it with osm0sis' script:
Download from here https://forum.xda-developers.com/showthread.php?t=2239421 the sdcard Fix Permissions script http://forum.xda-developers.com/attachment.php?attachmentid=3761904&d=1464187934
You may wish to back up your data with TWRP or ensure you have your photos and videos somewhere safe prior to flashing this.
Reboot to TWRP and backup your device.
Flash the above script.zip in TWRP and wait for it to complete. (it should be fixing the permissions in /data/media)
Reboot and you should be able to download/update apps again from Google Play afterwards. You may have to uninstall the app and re-install the app if it keeps failing.
I've got this working on a XT1642 running June 2017 stock ROM, rooted with magisk 13.3 and apps including Snapchat and Google Chrome update without issue now.

Useful info, this happened to me a couple of days ago. I thought it was something related to the integrated Chrome WebView in conflict with the system WebView, because it only happened when i tried to update Chrome, or any of his variants (dev, beta, canary, etc). Thanks.
