Any way to flash twrp without losing data? - Samsung Galaxy S7 Edge Questions and Answers

I'm currently hesitating whether or not to flash twrp (to test the stereo sound mod for now, but I'm sure there will be plenty other reasons in the future). Thing is, I filled my phone with tons of customization settings, spent hours (literally) restoring my 30k sms from my old phone, and I just don't want to lose all my data and even the internal storage when I flash twrp!
Is there a way around that bootloop that does not force me to lose everything (or some way to fully restore nand afterwards)?
Thank you guys!

Increasing system storage with every update?

I tried searching for awhile and couldn't find anything too related to the exact question. Seems like with every update coming out storage shows the system taking up 1gb more than previous. Its as if it doesn't delete previous android versions. Its gone from 2.5gb few updates ago to now 5.6gb but the android updates are no more than 1gb. Its about when I started to notice this, 3 big updates ago all being around 1gb each.
My phone is completely stock, would a full stock flash delete everything and start the phone over? Also reading the general topic a few different methods mostly for unlocked bootloader., which one is the best for a locked bootloader? I was wanting to do this anyway because I have other unrelated issues with the phone such as gboard constantly crashing and photos not storing properly/overlapping eachother in memory that seems to happen with every update no matter what.

Before doing anything rash, you should probably start by clearing cached data @ Settings.>>Storage>>Cached Data. Also booting the phone to stock recovery and wiping the cache partition may help with any apps that are wigging out. Lastly, you really cannot "flash" anything with a locked bootloader. You can, and may later decide to wipe/factory reset from stock recovery. That would wipe your data and return your phone to the blank Android version you had installed last (7.1.2?) and yes, it would wipe/reclaim space, but you can do that manually without a factory reset. Before you go down that road make sure you enable the Google backup of your account so all your app/app data is saved. If you have photos, let Photos sync fully before the reset so your photos will be backed up to the Cloud. Also note that if you decide to unlock the bootloader (good choice) it will automatically perform a full wipe/factory reset. There is a sticky in General on how to do this.

Thanks for the input, but thats something I've been trying after every update already.
I found another site with clearer setup and instructions to do a stock flash with a factory rom and not OTA. Only reason why I had an issue with not wanting to unlock the bootloader was because im on windows 10 creators and it uses powershell now. So I had to figure out how to use fastboot/adb with powershell since cmdprompt wasn't the same. Doing a flash of a factory rom indeed fixed my gboard/photo storing overlapping issue that every ota update and factory reset through bootloader wouldn't solve.
Although my original question still remains, the system data in my storage is still 4.5gb with 7.1.2, better than the 5.5gb it was but I'm pretty sure its not supposed to be that big, any ideas why every update keeps taking up more space on the phone? The rom was even 1gb being flashed on the phone and I swear I remember the amount of space it took up when I first got the phone was around 2gb.

I always flash a full images- not OTA... but I've always been unlocked on all my Nexus devices going back to the Galaxy. You cannot flash a full image without unlocking the bootloader but yet you say your bootloader is locked? For comparison, my untouched System is using 4.57 GB. I am running stock 7.1.2 ROM, rooted and EX Kernel.
PS...there is a toggle switch in Windows 10 settings to select command shell or powershell. It's as easy as a toggle to restore the command shell (or switch back).

Complete backup???

I have Verizon Note 3, with Jasmine Rom and TWRP recovery.
I have posted a question about my phone started showing some sh** dialog over and over about facebook app not responding.
Till now i havent found any solution to it. So, seems as last resort, i will flash again with jasmine rom (if there is anyother better do tell me). But before that, i want everything (EVERYTHING) to be backed up, text messages, my games data, my installed softwares, cracked versions, everything. Is this possible???
Anyone coming to save the day????????
First you need to state whether you have a safestrap ROM or a unlocked bootloader and real custom recovery. Huge difference.
You should also bear in mind that if you are suffering from a corruption issue somewhere, a "complete" backup and restore merely records the corrupted data and restores the same corrupted data. What exactly would you gain that way?
Your hypothesis suggests you think a fix could be acheived by "refreshing" just the ROM (i.e. the /system mount). If you have any customizations in there, they will be lost unless you can identify them and re-create them after you have "refreshed" the /system mount. If you are unable to do that, you will lose them.
If you thought that you were unable to identify those changes and were going to plunge ahead and try anyway, theoretically you would get the same result by just flashing /system only and wipe the /cache mount without doing any backups at all. EXTREMELY RISKY MOVE THOUGH IF SOMETHING GOES SIDEWAYS. (You should always assume that something will go wrong and make backups... and get those backups off the phone in case the entire device needs to be wiped in a "start from scratch scenario)
Note that your apps have been under constant update all this time since Jasmine's release while it (Jasmine) has been standing still. There's no guarantee that what you are observing are not merely bugs in Jasmine uncovered by new application code.
A Herculean, careful and diligent backup & restore operation might fix nothing.

How do I fully backup my phone in a way, which means it can be restored semi-easily

Hey everyone,
I understand the title may be confusing so allow me to elaborate:
Currently I would like to do some riskier things to my S8 (change boot animation and splash screen etc..), and I don't want to permanently break it, I'm very new to the whole 'rooting' thing. So I was wondering if anyone could help me with backups.
How does one "fully" backup a rooted S8 and how would one restore such a backup with a decent amount of ease.
I've researched it but I am struggling to understand some of it.
Thanks for taking a read through!

Once you install twrp you can make an image of the phone, tap restore and it restores the whole image, doesn't get easier than that.
Another vote for TWRP.... One of the things I miss the most with not being rooted. You can save various backups of different ROMs, then restore them at will... I would jump between a different ROM, about daily (sometimes 2-3 times a day). That's why I went with a Samsung (in the US), because they're hard to root (correctly).....And now I don't spend hours, each day, messing with different ROMs. But I do miss it.

Lenovo A6000Plus Bootloop problem (Unrooted device)

Good day everyone, i am going to report my delicate and infuriating problem that has been haunting my head for two months
I'll describe my problem in extreme detail, hoping you guys able to identify this disaster.
My android phone is Lenovo A6000 Plus, i've bought it 2 years ago and it's running on latest Lollipop version 5.1.1 I never alter the system files, since i only use my phone for games and communications, and i'm not really into tinkering android's software. so i use my phone like a normal person, do the updates when the settings asked me, update the apps, etc. and this phone running smoothly in my service. i wanted to ask both WISDOM and HELP in this thread.
1. The Bootloop disaster symptoms started on april 2018, when the phone boot SLOWLY AS HELL, seriously.. it took about 1-2 hours to boot, and it also shows the (ANDROID IS UPGRADING 0/132 apps) like wtf? , i haven't update or install any new android apps before this symptom happened. So i leave my phone plugged in and wait it to complete the upgrade; then it worked normally as it should. Unfortunately, it happened EVERYTIME i turn my phone on, EVERY SINGLE TIME.. T_T. so i struggled to avoid my phone from running out from battery as i can. This symptom happened for 3 weeks and it got from bad to worse. I wonder what kind of problem is this?
2. The worse part came when my phone is running at high RAM usage, let's say, i game on my phone alot in my spare time, using the ram up to 1800mb everytime i play game or open chrome browser (Lenovo A6000 plus have 2GB ram). When i close/task manager the apps, my phone launcher wont appear normally as it should (long pressing bottom left button) and it FORCED me to restart the phone and suffer the 1-2 hour LONG BOOT. That's unusual, i cleaned my phone regularly (using cleanmaster) and preserve both of my internal and external storage with 3-4GB free space. I wonder what kind of curse is this?
3. So the bootloop disaster finally got me this May when i turn my phone off and tried to reboot. And... no Android is upgrading 0/132 showed up, i waited for 4 hours and reboot my phone again and again and again. And its finally STRANDED on BOOTLOOP :crying:
Im on panic mode when problem 3 happened, then i searched the almighty Google for help, and found that i can backup my data with TWRP recovery, so i do as it said, followed the guides and BACKED UP all of my data.
For once i felt relieved my data is now saved. Now onto the main problem.
I've had enough of this problem so i format the phone into factory reset, wipe the Dalvik ****s, cache, system and data. All of it. thus, making my phone virgin again.
4. Now im trying to resurrect my phone, and tried my effort by downloading Stock Lollipop 5.1.1 OS again along with its prerequisites. I tried to zip-install it using TWRP but it said that "has not switched carriers and cannot be upgraded" i scratched my head and searched almighty Google again then found that i need to do ####6430### thingy before doing that. umm.. so my phone domain need to be changed, how can i do that with a phone who can't boot? (I'm from Singapore btw). What did i do wrong?? did my phone just turned into useless BRICK? but i've read that bricked phone can't even start the recovery, yet my phone still able to start either with Lollipop stock recovery or TWRP (if i adb fastboot it with adb tools from .cmd), so it's not totally fuc.. uh., BRICKED and i got the chance to fix it.
TL;DR
So, Guys.. i desperately need help. i'm a peon both in work and college, and a dead phone will not make a great company for a person like me.
I searched for enlightments and breakthroughs but always ended up failed resurrecting my phone, can you guys PLEASE :crying: tell/give me a SAFE and WORKING walkthrough to re-install my Lenovo A6000 Plus with Lollipop 5.1.1? And does it running a custom OS like those Cynadrogen thingy is good and worthy enough to speed up my phone? is the chances of getting bricked is unavoidable when running custom OS? I thought its going to be easy like reinstalling Windows, but i was wrong.
FYI, my phone now is UNROOTED and running on TWRP 3.0.2 and i can easily revert it back to Lollipop stock recovery if needed (does it considered rooting if i install custom recovery?) I also need a valid info if my phone would never turn like this again if i resurrect it again.
PLEASE HELP ME PEOPLE
THANK YOU.. ! :highfive:

When 5.1.1 update arrived?
Okay lets get to the point. Just don't panic. You have the stock rom file, extract a file named 'system.zip'. Now go to TWRP, perform advance wipe (wipe dalvik, data, system and cache partitions) and flash that file from TWRP. You'll be on stock rom with a fresh new experience.

Custom ROMs are amazing and far better than the stock lenovo rom. Believe me, no one here is using that crap stock rom. You just need some instructions to flash and your phone will get a new life. We are here to assist you.

Note 4 internal memory recovery. Root without losing data?

Hey there folks so I have a Note 4 that has been giving me lots of difficulty. I was hoping to upgrade but it looks like that is still a long ways off. I'm only willing to give up my S View and battery for the Note 10+ lol.
About a week ago it just shut off and when it came back on it was in setup mode. I lost everything, or did I?
Now it only has 421MB of the 32GB actually being used but it always says it's full. So apparently the old data is still there I just can't access it. I know nothing about rooting and I don't want to root and install a different operating system I just want to do a root to keep everything as is just give me access to the internal storage entirely.
It looks like when it reset it created another partition maybe?
I have thought about doing a factory reset but I don't want to lose the chance to possibly recover this data.
So is there a way to root so I don't have to get rid of everything and flash a whole new OS/UI?
I would research more but I have autism and this is all just getting very overwhelming.
I can't seem to figure out how to post screenshots.
Thanks for your help
