Battery drains extremely rapidly. Recommended firmware to flash? - Samsung Galaxy S7 Questions and Answers

So my sister gave me her S7 after my Sony Xperia XA2 refused to read my new Verizon service. So I flashed the Verizon firmware since it was on AT&T's firmware (which disables the bands for Verizon) and it's awesome. Super snappy, super quick, good 4K video camera, the works.
The only problem is that the battery is draining faster than my iPhone 6, and this is just with responding to texts while I'm at work. Like today, I worked 5 hours and it went from 100% to 32%.
I read that there is a firmware I can flash with Odin that will greatly help the battery, but I'm not sure what it is. I really dont want to brick this phone.
My S7 is not rooted btw.

First off you it's a US S7 which means the bootloader is locked which means you can't flash Twrp (Custom Recovery) which means you can't flash a custom rom or obtain root threw recovery what you could do is see about rooting it first i believe the root for the US S7 is threw a modified boot image that is patched threw Odin you would have to researcher that first after you obtained root then you have 2 options debloat the phone yourself which I wouldn't suggest cause if you remove something vital to the phone it will soft brick and you have no custom recovery to revert to a working image of your phone and you going to have to flash a stock firmware in Odin to fix it second whkch I do recommend is see if there are any roms for your model of phone that are flash fire flashable that you can flash again the process with this is one error and you will have to start the process all over again.... If you going to debloat after you obtain root just remove Samsung apps and Verizon bloatware and you should see a speed and battery increase just off of that alone... If your bold you flash xposed threw flashfire and open up your options even more.... Flash the wrong xposed and you Wil soft brick and have to start over again.... Some Samsung phones can take the official xposed for your sdk or need the alternative xposed for Samsung to work properly don't know which one yours fall under.... Good luck [emoji1696]

[Q] Can't update, downgrade, or rest to stock OS, PLEASE HELP

Good afternoon all if anyone could please help I'd greatly appreciate it!
So I just bought a Sprint Galaxy S5 from ebay with the assumption that with some customizing I'd be able to get the phone domestically unlocked. I got the phone and it was already updated to 5.0 Lollipop so I followed this tutorial to get the SSU.apk to actually work
http://forum.xda-developers.com/spr...locking-sprint-galaxy-s5-g900p-t3085624/page2
After a lot of time I was successful at rooting the phone and was able to downgrade to 4.4.4 but the tutorial calls for 4.4.2 but it seems that 4.4.4 was the only fw that would successfully install.
But now here's the problem I was able to obtain the domestic unlock code through Sprint but now the activation/update app doesn't work and doesn't open automatically the way that the reps said it would,. I've tried to reset stock through Kies but Kies doesn't recognize the phone. I've also tried to use Odin through out this process not only to reset back to stock but also downgrade the fw and the modem. The really annoying part is that small PDA/AP updates and installs work fine but when I try to Odin the original tars it always fails 100% getting a "sw rev check fail aboot fused 2 binary 1 " error on my phone.
I really don't know what to do at this point, and it seems the error is associated with a soft brick but the device still powers on and boots.
I thought this would be a pretty straight forward process but I've hit the wall and am losing my mind, I need help!
P.s. I flashed 4.4.4 fw with CWM and the device is still rooted
Thanks

Samsung Galaxy Sol (Cricket)

Hey everyone I was hoping for a little help on this 1. I just purchased the Samsung Galaxy Sol (SM- J321AZ) AND wanted to make a back up and possibly flash a custom Rom on this device if at all possible. I have the Galaxy Tab E 8.0 (SM- T377P) and third to do the same thing without making a backup and not it's pretty much a paper weight as every time I download a .tar file it won't flash and none of the major websites have a factory or custom Rom so that I can use it again. (If anyone can help on that as well that would be SUPER AWESOM). Anyways, I don't wanna make the same mistake with this device as the other so I figured I would ask for some help. I need to network I lock the Sol phone as I'm a T- Mobile user but this was the only phone they had at the store that was not a flip phone. Hope someone out there can help.
Thanks in advance.

Galaxy Sol? I gotta admit, I had to look that one up; never heard of that one before. It appears to be brand new, having 6.0 and released just last month, but it's not even on Cricket's website. Weird.
As far as custom ROMs or even root goes, you're probably SOL (pun totally intended), at least for right now. However, Cricket does like to rename a lot of their phones that are otherwise identical to others, so it's possible a root method may exist.
When it comes to carrier unlocking, things can get a bit tricky. Cricket sells phones for fairly cheap because they only sell them to their own customers. In other words, they know they'll at least make up the difference with a minimum of a couple months worth of service. I gather you've purchased this phone second-hand. If it's not already unlocked, you might not be able to get it unlocked short of one of those services you see on eBay. Contact Cricket about it. They have rules and limitations about when and if they'll unlock their phones. Root/ROMs typically can't do anything regarding carrier unlocking. Interesting though that so many newer Cricket devices, even the cheapos, happen to have band 12 for T-Mobile.
I just bought this at best buy a few weeks ago. This phone seems to be exactly the same as the Samsung Galaxy Amp Prime SM-J320 with the exception it being 8GB.

CRICKETWIRESSDOTCOM/cell-phones/smartphones/samsung-galaxy-amp-prime.html
Either way, I was unable to find a stock fw for either of these phones however the firmware allow for OEM unlock. I was looking to at least root and clear away the garbage because out of 8gb I can only use 3GB (also install apps to SD). I don't want to do this unless I have at least a stock fw backup rom to load.
Is there any back door way of downloading this stock firmware? I've look far and wide. Any assistance would ease the pain. Thanks.
here is a link to the stock firmware

Just head to my new post with links to the firmware. http://forum.xda-developers.com/general/help/samsung-galaxy-sol-sm-j321aza-little-t3420635
This phone is currently $50 at Best Buy. I want to buy it for my mom(she's using my old Nexus 4, which is slowly dying), and this seems like a decent replacement. The thing is, she's on T-Mobile. If this can be unlocked to use on any gsm carrier, that'd be great. I guess I'll have to look around eBay or ask Cricket about unlocking it.

And then I get to deal with the frp lock. I don't have the info for that either, But would it be easier to bypass the frp instead?
I'm not entirely sure but aren't the spec for this the same or almost the same as the Galaxy J3 or the Galaxy amp prime? Would anything from those devices work on this. Like a rom port or root method

that selinux root method earlier in the thread does work for root, and after root just adb shell pull all partitions to port twrp or brew a rom. the specs for the j3 and prime are nearly identical so porting from those two should not be to hard. i went to a new phone so i wont be doing anything further with it. unless i get bored and decide to fish it out the junk drawer for something to do. https://drive.google.com/open?id=0B1rwlbcYZ8i6NldnV0ppVHJ3Z1U thats the link to the adb file for root and the instructions are here https://forum.xda-developers.com/android/general/release-root-samsung-galaxy-prime-j320az-t3493077 . Sorry thats an Odin flashable boot img with selinux tweeked. sorry havent paid much attention to this phone lately
Ok thanks I'm going to see what I can do. At least TWRP and from there compile a rom. I have nothing but time and patience so I'm gonna build cm13 and see what happens.

What is the method to fix SM-G930U when the eng-boot cause boot loop?

As title said I have the flat SM-G930U because I love being able to switch provider, and so far I'm ok with the phone, but I really do miss my root. I was ecstatic when I saw that root was achieved and bought my unlocked S7 off swappa.
Long story short, every time I try to install the flat G930A eng-boot tar to my G930U through the modded Odin, the phone "WILL" force restart itself soon after booting into the main screen, or even when I leave the screen off. This process is reproducible every time from a stock restored G930U image.
So far I've had to resort to restoring to a stock image to fix the problem so I cannot get to the rooting part yet. Is there any other better method out there? I hate to have to back up and restore my data through cumbersome means like Samsung Switch or Helium.
If you have this G930U model as well, can you share your experience with the rooting process, and/or the experience with the phone so far with root installed?

I think that nobody has yet rooted it, since it just recently came out. The reason why it doesn't work for you, is that the engboot is meant for another model. You'll just have to wait, until the engboot is also released for your model.
I have the exact same problem. SM-G930U reboot loop after loading the engboot. I would love to root this phone if someone can release or locate a compatible bootloader!
Actually, it has been almost a year now. Surely a bootloader for this device is available now? I cannot find it though.

Cool, did not catch that.

Need help with finding a de-googled rom or options.

I have a G930v which we all know can be crossed flashed.
I am switching to freedompop but that not the point of this thread.
I did do the nogut root but none of the modification for battery non performance, something happened where the root came off and I get "unauthorized app" but knox isnt tripped.
so I decided i'm just going to wipe my phone and start over.
I want a de-dedoxed , de-bloated, and de-googled phone, running root and xposed, because I would like to run MicroG on my phone.
Whats the best and lastest firmware from updato? I should download since samfirmware takes forever and a day to download.
any help is greatly appreciated.
You can only flash stock, so any G930U (unbranded) ROM would be the only option but they're not "de-google'd" as you put it

SM-G930V

Greetings My Brothers. I have a huge Problem. Sometimes ago I got a Samsung Galaxy S7 Verizon Model, thought it will be cool to have such a model, just come to think of it; Snapdragon 820 what else did I wanted again. And the phone started running Berserk. apps downloaded and installed from PlayStore don't work at all even WhatsApp does work properly. The phones freezes all the Time, it overheats all the time. So I made a decision. root, install custom recovery and install Custom Rom like lineage OS. I'm accustom to those stuffs like Odin, download mode, etc. I don't have any problem with a phone stock on boot loop, it's something I have been fixing, so I'm Used to It. My SM-G930V security level is High with its latest android version Oreo, the bootloader is locked. tried to unlock it with ADB and Command Prompt. It was a failure. tried to get some help On YouTube. Failed, all the videos I watched was about SM-G930F none of them talked about SM-G930V, I came across SM-G930V bootloader Unlocking, rooting and custom Rom but, it wasn't compatible with my SM-G930V. So let Me ask You Guys this question. Can I really unlock the bootloader, root the phone and Install a custom recovery, and A custom Rom??? If there is a slight chance or possibility of doing so, please Brothers help me out, because I am unable to use the phone to its full potential. Thanks. Michael.
