Downgrade 6.0.1 to 5x?

[Sdanbow]

Ok, go easy on me.
Since the upgrade from Lollipop to 6 my verizon Samsung S5 was slower with lag but still bearable. However after today's security patch its so slow it's almost unusable. How can I force it back to Lollipop?

I know almost nothing about rooting/JB but willing to learn something new as long I don't brick it. I just don't understand the terms and risks and process. Where do I start?

Thank you.

Go into settings ->storage ->internal storage ->cached data, ->delete. Restart your phone. I assure you a newer version of Android is not the reason your phone is slowing down.

That was first thing I did, then booted in to save mode but neither made a difference. It was fine utill I accepted the update yesterday morning. After it installed it has been EXTREMELY slow. As i type this it lags on key presses. It was definitely the update.

It's impressive that on so many forums everywhere people decide they need to only give their own opinion of situations instead of answering original poster's questions.

While I'm also skeptical that an official update would be the cause such a massive slowdown on his phone, that's not really what he asked to be addressed, even if the answer may be obvious to some.

Unfortunately as your S5 has the Toshiba chipset (emmc of 11) there is no way to downgrade the firmware to Lollipop or KitKat. The bootloader is locked. You are out of luck unless you or someone else figures out an exploit.

You can start here: https://forum.xda-developers.com/ve...t/rd-unlocking-galaxys-s5-bootloader-t3337909 This explains in a good bit of depth the current status of Verizon S5 bootloaders.
Other than that, just start searching and googling. It's probable that someone else has a similar issue as you. And like Rumsfield said, it's highly unlikely that an official update (which is what it sounds like you have) would be the cause of such a dramatic change in your phone's speed, so it would be worthwhile to investigate further. Have you deleted your dalvik/cache in the recovery? Have you done a hard reset? These are things you have to do before you blame the firmware, and if you have done already, it's a good idea to mention that in your original post so that you avoid unnecessary responses.

Good luck!

Its impressive how you think you are some sort of voice for the internet police. I doubt its the update and deep down you do too. Just trying to help the guy avoid making a mistake by downgrading.

I have a very uneducated question to ask, don't or do The FOTA logs in the recovery menu contain all check values and patch notes old - new? Again bare with my lack of knowledge on this topic but if pushed ota and still in log can it be pulled although maybe enough info alone in log for aboot and other values as far a checks but can it be modified even with filler as what it looks like on a battery self check and re injected through command as OTA? Last question before I'm stone to death for being the forum idiot here...if something is odexed and after the patch now labeled an 8 digit number kinda like Cid or emmc or whatever the long as chipset number for instance has the another value as an I'd in the middle of it can it inturn be reversed so parameters are matched and verified and possibly editited? Thanks

Oh. Forgot to ask I didn't see a check after the
command: "/sbin/recovery" "--update_package=/cache/fota/update.zip" "--carry_out=open_fota" "--locale=en_us"

Is that a forced allowable command? The real last question and believe me I have searched threads with no luck but the mention of a dev phone and aboot.mdn

Is the recovery file system table
0/boot emmc/dev/block/platform/msm_sscc.1/by-name/boot (/dev/block/mmcblk0p15) 0
1/ ect...
2/ect..
If the 0 is a 1 would that turn any phone into dev phone or allowable options
And noticed the checks were against the chipset and matching verizon fw although att and tmo had 0 values if values were 1''s would that allow you to you the right matching chipset for att and it's fw tmo ect.. or even the 15mmc instead of the 11?

No idea what you are actually asking because you are talking like a terminator sent back to April 11, 2014 to start some sort of war about a very old phone. Obviously triggered so hard you made a new account.

Huh? I was just asking a question? New account? Must have me mistaken sir. I was curious about this phone what options there were after the update to gain root access I have never chimed in as I was trying to read all past and present post on this topic kind of gets a little confusing one would think outdated post and procedures would be deleted or timestamped to where if the method dosent work anymore why have it up unless only as a reference. But thank you sir for no guidance or help at all.

You were asking a question that was very convoluted from a "new" account, turns out you created it like 3 years ago and never posted. You quoted my response to someone else asking your question which to me made no sense, hence my weird response to you. I still don't understand why you are posting in this thread with that question unless you are trolling.

What are you using for recovery? I have two S5's now running

Ok so first your warranty is void (gone) also make sure you backup your phone like photos etc take screenshots of needed text messages also your phone has an 11 CID (I sadly have one to) Like you mentioned which is not unlockable so we have to go back to Lollipop to root and what do you get with root you get the ability to flash custom Touchwiz based roms anything aosp/cm/linage wont work because our bootloader is locked and there is no current exploit to unlock them there is alot of Touchwiz based roms available I added screen shots on how my S5 looks I'm running Alliance rom I have added the themes from an older version of Alliance rom and added Viper4arise Viper4arise is a really cool sound mod it gives you increddible sound there is also xposed framework now if your interested in rooting download the drivers http://developer.samsung.com/galaxy/others/android-usb-driver-for-windows extract the zip and run the exe then download odin from https://androidfilehost.com/?fid=673368273298975100 extract the zip and run odin now power off your phone and hold Volume Down + Home + Power then click Volume Up To Accept then plug your phone into your computer make sure it shows Up in Blue in the top left in Odin Should say something like "COM" now download https://androidfilehost.com/?fid=673368273298975100 that is your lollipop tar.md5 download that and extract the zip now click AP in odin and select that tar.md5 you extracted from the zip odin might freeze but its verifying the file once its verified click start this Should downgrade the phone now you might have to pull the battery if the phone wont boot afterwards (stuck on Red Verizon Screen) and boot into recovery by powering off the device (Pull the battery) and then Holding Volume UP + Home + Power untill you see "Recovery booting" in the top left now use the Volume buttons to scroll and power to select go Down to Wipe Data / Factory Reset and click power button once its highlighted now use Volume buttons to go Down to Yes and click Power to select it when it is finished click power when Reboot now is highlighted now root the phone using this guide https://forum.xda-developers.com/ve.../testers-required-easier-root-method-t3561529 or this one https://forum.xda-developers.com/verizon-galaxy-s5/general/root-method-og5-ok3-t3290370 if you ever need help you can Private Message me on XDA.

You can even go back to kitKat and safestrap will work But you have to root 5.0 First here is a guide I made https://forum.xda-developers.com/ve...al/how-to-install-kitkat-lolipop-pb1-t3589151

understandable. no i usually have not ran into many problems before. as it has been years since i messed with these phones and decided to mess with them again alot has changed i updated one of them and was looking for a way back being it has the 11xxx toshiba chip. as far as replying to quote i have never posted before i just thought i was replying to thread or whatever but just glad i received a response lol. i was just curious i was looking in the recovery menu at the logs from the FOTA update that i accidentally accepted. noticed they were very detailed which i thought was unusual. Again very very detailed like source code or whatever the raw format is called and was curious if it could be pulled with an adb command. the second part was a shell script whatever excuse my ignorance when it comes to this but after they were ran they were checked/verified or whatever and showed values that must have been met, which lead me to ask about is there a way to use adb to unlock the boatloader as an update.zip? thanks
