flashing roms and file size question - LG V20 Questions & Answers

i have always been in the background on this site, but i have using y'all since i had a galaxy s2, note 3, vivo 5r and a few others.
I have boot and root on my phone (h910) and I'm trying to flash a few roms, but i haven't been successful. I looked at the lineage roms which seem to be the base for a handful, but the file size that i see are only like 435ish MB?? Then i tried the mega rom (4.0) because it has what appeared to be a full file, but it crashes and gives me a green screen on boot. I'm waiting for the super rom to come back since it seems like it will have the most up to date files and it has a large following.
Is there something i am missing on the small files? i cant seem to find a rom or a lineage rom that's a gig or 2 in size..
I recently did all the unlocking this past weekend, so whatever the latest links are for that stuff is what i used.
twrp 3.2.1-1 (think that's it)
h91010r
nrd90m
super su v2.82

Stock based ROMs will be around 2gb in size. Those need to have everything included (system, kernel, boot, vendor, recovery, efs etc partitions) while aosp ROMs like lineage are around 500mb. Those don't need to have all of lgs other crap.

that is good to hear..
4**MB is the actual rom and all the guts it needs to run then the rest is just "fluff" wow!?! Just want to double check I'm hearing that correctly

You are indeed hearing that correctly. Aosp ROMs don't touch the bootloader, vendor firmware and other LG firmware. They simply replace your lg H910R system with aosp. Stock KDZs are upwards of 2gb in size and because of how stock based ROMs are built they need to function essentially like a kdz - updating all lg specific firmware as well to make sure they are all compatible with the newly installed system.

[Q] Fusion ROM 5.0.2 Galaxy S5 klte. Need Explanation On How You Update it.

Hi,
I have a stable and working Galaxy S5 klte with Fusion ROM 5.0.2.
It's overclocked etc and I'd like to know how to update my ROMl without losing my settings.
I used to run with CM12 5.0.2 but that was easy update with twrp and I still had my setting and the update.
I got twrp here as well and root obviously but I'm not entirely sure how to update this ROM.
Current Fusion verison: Fusion-v5.0-2015-01-27
Dowloaded:
Fusion-v5.1-2015-02-07-fusionsp_klteusc.zip.md5sum(0,13kb)
Fusion-v5.1-2015-02-07-fusionsp_klteusc.zip(252.42 MB)
I just need to know how to install this and keep my settings because my current ROM is very stable and the kernel is up to date.
A little info about what's on it and working:
Working: Camera(amazing photos and 4K recording), NFC, Bluetooth, WiFi, LTE, Viper4android(amazing sound/surround.) And all basic stuff like calling/messages.
No crashes, lags or stutterers. It's smooth like butter(smoother than any iPhone, 6+ and note 4(testet it).
All my apps/games are working perfectly and smooth.
Specs:
klte 5.0.2(obviously) running Nova launcher, usually 1,1gb RAM available.
Antutu benchmark 47.XXX evern up to 48.XXX went above Note 4.
I/O scheduler: vr
CPU: 2,764 MHz
GPU: 657 MHz
DPI: 528
Governors: usually on performance with great battery life and not overheating.
Fast charge enabled and fully working.
I will appreciate it so much if I get an detailed explanation on how to update my ROM but still keep my settings.
You update custom ROMs the same way you update any custom ROM (apart from the very rare cases when the dev included an OTA updater)
Flash from TWRP

So I just basically go into twrp recovery>install and check the 2 files I have downloaded?
Are you sure about this?
Thanks.
Edit: I can only see one of the files twrp install which is: Fusion-v5.1-2015-02-07-fusionsp_klteusc.zip(252.42 MB) the .md5sum(0,13kb) doesn't show up?
The MD5 file isn't flashable, just to check the ROM is not damaged before flashing
You just flash updates the same way as you flashed the ROM to start with, the updated version is a full ROM, not just an update - so you can flash over the top, or wipe and flash as a new ROM
Generally speaking, I would wipe SYSTEM and CACHE, then flash the ROM & GAPPS, but as it's an updated version of the same ROM, flashing straight over the top will likely work fine (Dirty flash)

The whole point was to update without losing my settings but I guess that's not possible if I wipe system?

The majority of things like homescreen layout and apps etc are saved in DATA, only actual system settings are saved in SYSTEM
Just go for the dirty flash first, only wipe CACHE - if you run into issues, wipe SYSTEM and flash it again

Alright, should I leave Dalvik Cache?
Sorry for so many questions I just need to be sure.
I'll do a backup and go with the dirty flash.
Wipe all CACHES, to put it simply, they are basically temp folders

I just tried it both ways and got this.
E: MD5 does not match
E: Aborting zip install
Failed
You copied the ROM.zip and the .MD5 to the phone/microSD before flashing?
If I remember right, with TWRP you can disable MD5 checking before flashing
This whole process is the same as the process you flashed the previous ROM version with, apart from the wiping everything part

You can skip doin MD5 on backups with twrp.
But I know that Fusion has his own version of twrp which might do the trick.
Doesn't sound like the TWRP version is the problem if it thinks the MD5 is not matching, unless for some reason this version can not read fusions MD5 files, but worth a shot I suppose
Did you unzip the MD5 if it was zipped?
Maybe the download of the ROM was corrupted
Where did you get it from, I can't see an XDA thread for that named ROM (Could be blind)

I got it from Fusions downloads/updates in the phone settings, you can also get it from fusions site
I installed fusions twrp and removed Caches did a "Dirty Flash" and it worked. Fusions twrp skipped MD5.

Here's a XDA about it but I didn't get stuff from there, just fusions site.

Thank you very much for your time and help. Appreciate it.
Ah good, pleased you got it sorted, yea they must have done something weird with the MD5 if they are providing a modded TWRP to skip checking
Thanks for the links, I`ll check it out

No problem.
I was really desperate to get the latest update since I made my settings exactly the way I wanted. And the only thing I wasn't sure of was how to update. Now I got the latest and I'm extremely satisfied.
You should definitely check this ROM out if you have a S5 that supports it.
With the right settings it makes the S5 top tier phone that actually beats note 4 in performance, the speed, ability to overclock GPU, CPU, increase DPI, fast charge, amazing and tons of features. I believe it's the best S5 ROM. It's unbelievable how smooth it is even with animations on it doesn't lag or stutter a single time. Simply a beast. The battery life couldn't be better either. You can see my specs on first the first post.
Take care.
My S5 is still a virgin at the minute, only had it 3 weeks or so, not even rooted yet because I jumped into Lollipop too soon before finding out about KNOX, so for now I'm just biding my time hoping for a root method that won't trip KNOX
I've favourited the fusionROM thread/site though, watched a video of it on YT too, looks a great ROM, definitely one to keep in mind for when I de-flower her

Oh I see. Well, there are root methods that can bypass Knox. I've read about it before.
I believe it was towelroot or something like that but idk if it's available for lollipop though:/.
You can also mount your SD card normally and save/delete anything from the phone, so all that bull**** is gone with this ROM.
Yea, everything changed with Lollipop, no root methods available without tripping KNOX yet
I`ll eventually fold and root it / recovery / custom ROM, but for now it's still a new toy and I`m happy with it as it is (Ads aside)
Plus I use mobile banking on my phone, and from what Ive read, it's a bit more complicated than just using a root hider to get it working when rooted, so a few things putting me off rooting atm
I've spent the last 4-5 years playing with Custom ROMs and recoveries, CWM, TWRP etc with the TF101 tablet, so I know my way around fine, but thanks to Samsung, things are not as straight forward with the S5/Lollipop/KNOX
Like I say though, it's only a matter of time before I buckle and push the button

I know exactly how you feel. The temptation to unleash all that power and speed is so strong. Not to mention the ability to outperform your friends new note 4 or any other top tier smartphone they get, just too much fun. I'm less experienced than you so I was a bit scared about the same things but in the end the urge won. And I don't regret it at all. Samsung's bloatware and stock ROM with touch wiz is just slow and unattractive. But yeah, it can satisfy you for a while the moment you get if.

Verizon Note 4, I have Root and BL Unlock. A few questions within.

So after blowing off the second half of my duties at work today, I managed to allocate enough time to get my SM-N910V rooted.
I have a few basic questions about what I should expect to see happen.
Allegedly, Verizon is rolling out an OTA upgrade to 6.0.1 Marshmallow sometime soon. Now that I have 'custom' boot and root achieved, will my device still receive and adhere to this OTA upgrade?
I have not applied any custom ROMs to the device. All I have done is follow the steps on this forum to unlock the bootloader and permroot.
If yes, cool!
If no, could someone please share with me a uniform resource identifier (lol) that links to a guide for installing CM13 to this device?
I will use my mind to beam eternal luck at anyone who helps me out. Thankyas.
Have you ever used Odin?
If you have twrp just load onto an sd or the phone and make sure to clear cache and wipe.

Yessir Mr. Nasty,

Just to clarify, you're saying that if I boot into TWRP again and clear the cache/wipe, I'll go back to factory settings and get the OTA?
If you have a microSD card, use TWRP to backup all of your current data to it if you'd like to preserve it and have something to restore if anything goes awry. Download a custom ROM zip and whatever other zips you'd need for that particular ROM, and put them on the card. Use TWRP to format data and wipe everything EXCEPT FOR THE CARD, and then reboot into recovery mode again and open the TWRP install menu.
In that menu, navigate to external_sd (or whichever root level folder it is that contains the strings "ext" and "sd", referring to the microSD card), and select the zip or zips (in the proper order) that you want to flash. Then flash them, wipe cache/dalvik, and reboot.
I wouldn't stay on a stock ROM if I were you. You might avoid getting the OTA, but you're guaranteed to avoid it by running a custom ROM. JasmineROM seems to be the go-to ROM for stability, but hsbadr's CM13 builds are very functional.

Thank you for being so specific and clear, and for helping me out. I am new to this, used to working on computers that I can tear apart more easily and change things inside of.

I dont know what everyone is thinking, but OTA will not work with rooted device. It will failed and in most case you will nee to flash full stock rom to fix it, then your bootloader will locked again. The best bet is to wait until Samsung released the rom and Dev here will modified it the right way so you can flash with TWRP.

Honestly, don't bother with CM13 yet. It's buggy. I was on it for a short while, tried a couple different builds but I got sold on the Note 5 port which is on 5.1.1. If you have any apps that don't allow mock locations, they won't work on any 6.0/Marshmallow ports (i.e. CM13) from my short experience. I could be wrong. I couldn't find a way to allow mock locations on CM13, so I went somewhere else.

I think CM13 is worth giving a chance.
I'm about 90% sure the MM update will come with a new bootloader (a locked one). I highly advise against trying to accept it if/when it comes. Someone here will tear it apart and make odin flashable images to get us on 6.0.1 TW rom. Until then, flash TWRP and CM13. I've been using it daily and it's one of the better CM roms I've used on any device.
Also look into Dual Boot Patcher so you can crack flash roms without affecting your primary one.

I might add to that storing a copy of that backup on another device... your desktop computer, perhaps, so that if something really goes bad and wipes your sd card, you still have a backup.
Do not, no matter how much your phone nags you to, take an OTA now that you're rooted. The odds are good that they've closed the exploit used to get root.
If you're looking for stability, Jasmine ROM is the best that I've tried. It's not being supported anymore, but it really doesn't need it. Everything works. I froze, then deleted every single Samsung and Google app that I don't use and it is just smooth.
CM 13? The last I looked, the camera doesn't work well, Bluetooth is problematic, you can't set your sd card as internal storage and a few other niggling issues. I've been doing this since my Droid Incredible and have found that ROMs ported from other devices will have issues until the developers marry the software to the hardware. I'm now waiting for the official Marshmallow to drop and let the developers take a crack at it.

Bluetooth is flawless. I can't see why anyone would set their sd card as internal (defeats the point of being able to move info between other phones and/or computers). Camera works very well (for CM). I've had very few issues with taking pictures. Recording video doesn't work for me. I've modded every phone I've used (I've owned many that I wouldn't carry due to no root) since the Eris and this is IMO the best CM port ever.

I am using PaulPizz 5.1.1 ROM and it's working almost flawlessly. I'm happier than ever with this phone. I want to wait for the OTA 6.0.1 to hit and the teardown of that to begin before I switch.
I'll look into dual boot.

I need your Galaxy On5 (USA) ROM

Hi, I need the ROM for this phone, more specifically, the boot.img file, as the current kernel is for the older, Indian revision of the On5, and my revision, the USA version SM-G550T1, seems not to have any copies of its firmware floating around. I'm running an OS for the SM-G550FY, which has no audio or camera support. Even if the version isn't an exact match, if you bought this phone in the USA, new, in 2016, your boot.img will probably work. I need this kernel guys. Please, if someone has an On5 in the USA, can I please get a copy of your boot.img and possibly system.img? I really care about the boot.img.
Thanks guys

Firstly, did you try the updated ones at these locations:
http://www.theandroidsoul.com/galaxy-on5-stock-firmware-2-86761/
http://firmwarefile.com/samsung-sm-g550fy
Secondly, why exactly do you need the boot.img, what problem do you think it'll solve? Is there any specific issue with your current ROM that you are trying to solve?
Yes, I did, but as you can see, those are for the SM-G550FY, not my SM-G550T1, and the camera and sound (including phone calls) don't work!
This makes me strongly suspect a driver issue, which could most likely be fixed by getting my hands on a copy of the factory boot.img.
Running Android 6.0.1 right now, compiled for the SM-G550FY, but I can't get it working.

Did they not work from day one or did they just stopped working after a passage of time or due to rooting or an OTA upgrade? If you didn't root or install a custom ROM, there is just no room for a software/driver issue to happen. Did you try wiping the cache partition and doing a factory reset?
EDIT
In any case, boot partition is the last place you look for actual component issues like camera or sounds. All the boot partition does is just kickstart your android OS and then the control is passed on to the system (as soon as the logo animation starts).

There you are! I just cannot emphasize enough that why don't you guys backup your existing ROMs before flashing a new one? It hardly takes five minutes with CWM/TWRP recovery.
In any case, what happens when you flash the Indian ROM (5.1.1)? I guess that could be your only option.
Otherwise, you can put a request on the CyanogenMod thread for your particular Samsung model.
For future reference, perform device backups and all the research before flashing a custom ROM, not after the fact.
EDIT
If you can contact Samsung support, see if you can manage to get a stock ROM from them that you can flash using ODIN or something.
I contacted them already, they basically told me to go **** myself. The missing ROM is a result of bad parameters I accidentally put in to Heimdall/ODIN flasher. I wanted to back up, but ironically, my first attempt at installing TWRP is what destroyed my ROM.
I've downloaded the kernel source code from Samsung and I'll try compiling it myself. If I create a working boot.img, I'll post it here.

boot.img is where the kernel is stored. I know, I decompressed it.

You are right, boot.img has the monolithic kernel, however, a lot of drivers are available as separate modules in /system/lib/modules/, so you need to make sure that one is proper too.
In case of Samsung, I think it was probably a mistake to use TWRP/CWM to backup or flash ROMs since they don't tend to work as well with Samsung devices as ODIN/heimdall.
Yes, do post the result of your output once you are done, so its helpful to others.

The kernel on this device does not have loadable module support. It's entirely monolithic. And, I'm having one hell of a time building a kernel this thing is willing to boot.
I really would love just to get a ROM from someone else's SM-G550T or SM-G550T1.
locked out by frp so i cant even turn on my sm-g550t1 so if you find the rom please let me know

I found a copy of the MetroPCS version: https://drive.google.com/file/d/0B_VtvT1vGmlsMjNnR2JvYzk0MFU/view?usp=sharing
You flash this with TWRP recovery, because those are tarballs and can't be flashed with Odin etc.
You flash TWRP for the On5 onto your recovery partition, and then restore from that.

thank you!
however, i can't install twrp to my recovery partition anymore because i got FRP locked, and i can't go into my settings to disable it now. so i think my only option really is via odin. i'll see what i can do with this though, thank you very much. i did have twrp on there before but after i got frp locked i can't go into recovery mode at all.
I've been losing my mind trying to make this work.
I think if I installed the stock recovery.img it may work, but I can't find it in the files you sent. Would you or anyone else be able to make a copy of it for me? I would be eternally indebted to whoever could.
If you want to go back to stock then use the official samsung software. I got a s6 tht a friend of mine straight up deleted the rom (idk how they managed that) and it wouldnt take to being flashed in odin. I put it in download mode and provided samsung smart something with all the info it wanted and it installed the stock rom and everything.

unfortunately smart switch is incompatible with this model phone for the time being.
I got four of these from T-Mobile when we switched from Verizon ($120 for 4 lines). Three of our Verizon phones worked well on T-Mobile (after a few APN tweaks), but my dad's old Galaxy S3 barely worked at all, and when it did, only got Edge for data. So I set one of the On5 phones up for him.
Everything was going great. I put the TWRP recovery on it, rooted it, froze all the bloatware, and backed up/restored his apps from the old S3. However, he wanted me to see if I could restore all his SMS/MMS. I tried restoring that, and the stock Messaging app started FC'ing. I installed Textra, which worked (and saw the old messages), but he never received new texts (even though he could send). So I tried removing Messaging and Textra, as well as the SMS cache (which seemed to be in "Dialer Storage (Phone SMS/MMS). I removed it, but now I'm getting an error every five seconds about "com.android.phone" and can't seem to get rid of it. I tried to restore the dialer storage backup again, but it just seems to sit forever without installing.
I've looked far and wide for a stock ROM... hoping I could just put this mess behind me, but I'm surprised to find it is nowhere to be found.
My other alternative would be to fix the com.android.phone error, but nothing seems to fix it.
Which cynogenmod or any custom os suits for Samsung Galaxy on 5.......please tell me guys.....I am bored with this official os
I was really hoping to come back to this forum and finally see stock ODIN files for this phone. I really, really want to get rid of the MetroPCS ROM I used to fix it.
Has anyone been able to find it?

Stock ROMs Factory v6.1 , v8.3 , v8.4 , v8.5 , v8.7, V9.0, V9.2-patch : v21

CAUTION TO NOT LOOSE TWRP
I read two posts that say v21, now again on V8.5, put the stock recovery back instead of twrp. This is probably a side effect of a fresh stock /system and wipe of /data.
As a preventive step, when done flashing and wiping reboot to recovery FIRST, before booting the system It will allow recovery to handle removing the recovery-from-boot.p that flashes stock recovery.
I just patched the modified V7.4.2 up to the newly released 8.3 now 8.4. 8.5, 8.7,9.0 -V9.2 Patch
New update has been made from V17 to V21 of the non prime version of R1-HD, Non prime is behind on security patch (2017-05-05)
Copied ROM from phone and made twrp install ROM from it.
* No preloader change (official updates change the preloader to block your ability to use sp flash tools for rom flashing)
* No lk.bin change __ this part is what allows you to choose boot options(boot menu when power and volume pressed together)
* No "FOTA" app Fota has now been left in to make it easier to get next update, if that ever happens.
* No opera browser
* No adds (removed in the modified 7.4.2)
* Custom boot logo (only done on v8.3, there was no interest in this so abandoned)
--Newer versions of rom left stock, Leaving mods up to user.
** while it is not necessary to do a wipe with this ROM, I still recommend it.
**Thanks:
** @vampirefo needed his patched v7.4.2 in order to apply this new 8.3 patch and again for 8.4
** @ColtonDRG OR @jasonmerc I do not remember which one made it: For the image used in the custom logo
and the modified zip is here .
Roms are rootable with SuperSU, flashed in twrp after install. Must be done in systemless mode. In order to patch system veridy in boot.img
Logo update did not work on original rom changing link to updated version
BLU rolled v8.3 back to v7.4.2 because of app compatability issues. V8.4 is there fixed release. Both 8.3 and 8.4 are modified prime roms with ads stripped
V21 is the non prime update.
Unmodified V6.1

I had that happen to my second phone too.
I don't have an explanation yet.
I even made a separate update.zip , that one didn't make the logo change either. I did eventually change it with sp flash tool.
I tried with both recoveries.
and multiple /dev location formats. and for whatever reason my one phone did not accept the logo change from recovery.
And the other test phone it worked.

Neither did I but it all seems to be working fine
Been using this for about a day now, likewise no custom boot logo, but that's fine. Otherwise, it's been running super well. A lot better than the previous mostly stock version did for me with the bloatware APKs removed after the install. A lot of the general idiosyncrasies of the previous version of the stock rom seem to have gone away for me. It seemed to have weird storage management issues, errors moving to SD, broken symlinks that prevent apps from moving or being reinstalled, and a lot of other little non-storage issues, but so far, none off that here.
Long story short, good work! I hope we eventually see proper 7.x roms through some of the efforts going on, but in the meanwhile, your work here has made life a little bit better on 6.
It seems that I was able to get the logo.bin to update when I applied the original update patch, but not when I used the same line in the rom install.
It is no big deal that it did not work, I was just trying to make it look different at boot time.
edit:
I think i found the problem with the logo not updating.
i used the update-binary from the official patch update. (the one that allowed the logo to change the first time)
and it changes . so since the ROM seems to install the way it is , only the logo didn't flash I put it in a separate update.zip if anyone is interested in it.
EDIT 2:
clarification.
It was not so much the binary allowing the logo to change but the format of the partition location I had been using that needed that binary.
Further test had shown me that I could have used the binary I was using but just change the partition naming line
Code:
package_extract_file("logo.bin", "/dev/block/mmcblk0p9")
the above code works with the same update-binary as rom install
But I was using
Code:
package_extract_file("logo.bin", "/dev/block/platform/mtk-msdc.0/11230000.msdc0/by-name/logo")
Taken straight from the official patch, and thats why it needed the update-binary also.
I dont know what is different in the binary other than , major size difference.
The powered by me logo was just a test file to see changes in the logo.
**logo-update is same as composite but with alt updater-binary
**composite-logo screenshot is in op
**stock logo will return to original BLU logo

Hahaha the scribbled "ME" is hilarious. Your work is awesome, I don't think anyone using this rom will have an issue with the boot image but thanks for being so helpful and explaining.
P. S. Do you have any plans with the Nougat update?

Nougat is going to take a full build from scratch. We don't have 100% identical hardware with any other nougat device to my knowledge. We might have the same MTK chipset, but there are several other differences. All we really need is an official device overlay and the vendor files released by BLU themselves. We can then apply those to the latest Lineage or AOSP (I prefer AOSP myself) and build. Then the only problem we'll run into is anything that has changed in 7.x that isn't compatible with our kernel we use in 6.0. It'd be a slight chance our current kernel would work without some patches on 7.x We can't even get our official sources for anything else, so I'm almost certain we'll not find any patches to for the kernel to work properly with Nougat, at least not from BLU or any similar devices. None The less Nougat has been well thought of, and we have been trying to debug issues with a broken Port. But a broken port from a different device is just that - Broken. We need a team of knowledgeable devs to build Nougat + Kernel from scratch and then we'll have it working. I can't do it alone with the old computer I have, the R1HD would be long forgot of by the time I got Android Compiled haha.
Mr. Mazak I flashed your rom it went smooth, I was hoping the newest update was for 6.0.1. But I didn't lose any functionality, hopefully on my Cricket Service this update has patched some things to the radio device that will retain connection more steadily. I experienced a lot of coming and going with the 7.4.2 rom. None The Less you did a good job with this update Mr. My suggestion is find the same MTK chipset with a fully working 7.x rom and just port the /System but keep all our libs and inits from this release just for a test starter. And don't replace the camera app thats in AOSP 7.x. )

It was just wishful thinking. I have no idea how all of this is done. All I know is @mrmazak has helped me to fall in love with my phone again with this V8.3. The 7.4.2 did seem a bit buggy for my phone but this update works beautifully and I didn't even root it. If this remains true I will be happy with this phone for awhile even on 6.0
Really confused right now.
I was browsing through the settings menus. And found in the Settings-security- menu a toggle labeled "quick boot" ( not to be confused with "fastboot") . I enabled it then rebooted to see if it booted quicker. Didn't seem to make much if any difference. So I went back to turn it back off. And it wasn't there. I checked in my other phone , it wasn't there on that one either.
Did any body see this menu item, and if so where is is it?
Edit 1:
Few more power off , power on cycles to compare times. With other phone and defiantly seems to have turned on some faster boot option.
This phone goes from off to on in 5-6 seconds other phone takes about 20.
Edit 2:
OK , I panicked for a minute.
Couldn't find the setting and thought that it was another way to block sp flash tool by preventing you from ever being fully powered off.
But the setting was in accessibility not security.
Mrmazak, first of all, thanks for the ROM, installed it yesterday. But I have a problem with SELinuxModeChanger app. First, I'm getting a security warning when installing it, then - when running it. And another message, with this app running - "can't obtain root", although SuperSU shows its status with green #, like every other app it gives root privileges to. On my other Prime phone, running 6.1 out of the box stock ROM, FM radio works just fine with SELinuxModeChanger app behaving flawlessly (no security warnings whatsoever). Any ideas?

The mode changer app is technically a security issue. I did have that warning a few times when using mode changer app from the XDA thread of the developer, then when I used the app downloaded from f-droid it worked with systemless root and didn't give the security warning.
The app downloaded from f-droid worked for me as well, many thanks!
Big thanks for getting this out, updated from previous debloated, rooted version to this modified 8.3 stock rom, rooted with SU v2.79 SR3, all is good - only App that won't show up nor install, even tried the ones off APK Mirror site - is my Dunkin Donuts App, LOL. Play Store now said it's not compatible and the APK started to install then failed - any ideas or suggestions on what to do ??
Otherwise, it's all good - I will survive without DD App, just run that from another device when I need my caffeine fix.

I also had an app that previously work, say is not compatible now.
Maybe has to do with apps that have links to pay accounts. And that has something to do with trustzone. (Tee1 & tee2)
Those sections I left out of the update. I will add it back in and test. Update when I do. It is also possible this problem is why Blu rolled back there update.
**EDIT**
well that didn't go well at all.
I flashed the new trustzone.bin files from the official update. Now phone no longer turns on and no longer connects to flash tool
**EDIT 2**
After much persistence and many failed attempts to get phone recognized in pc again. Finnaly got to a point that phone was cycling between "preloader" driver and "usb serial device", and with careful timing was able to start sp flash tool at just right time and the flashing back to original trustzone files seems to have recovered phone.
for the record i am not sure what steps made it work. But I was shifting back and forth between leaving phone sit on charge, then on charge with rubber band wrapped around power button, then not plugged in , and not plugged in with rubber band on power button.
Okay... persistence is key in customization, i guess! I am getting somewhere here!

Yes. You are correct
Either put the zip file on external sd card , put card into phone boot into recovery mode and install , or put file directly onto phone .
Many ways to do that.
Easiest is to copy to phone while phone is connected to PC.
Cam also download file from internet with your phone.
Bottom line is get zip file to the phone boot to recovery and install
Anyone else having wifi issues after upgrading? While watching videos it seems the internet cuts out. The phone says it's still connected but I have to turn wifi off and back on for anything to work. Could be my router also but it didn't seem to be doing this until I installed 8.3

Right on man! I am officially running 8.3 ROM with April 5th 2017 Security Patch Level! Geez.. it was not easy but I got this working!
MrMazak, I followed all your instructions on both links, so could you tell me what exactly I have on my phone? Is it rooted? Bootloader Unlocked? The phone seems to be working fine but I don't know what level of access I have. Honestly I don't even know exactly what the differences between all these terms are.
Also, do I have or not SU? One of the steps under the .bat I believe install it. How do I access it?
Thanks again!

Hi all. I'm new to rooting can any one please help and point me to the right tutorial to root a samsung s7

Hi All
Looking for a best tutorial to follow and the right one for my phone really don't want to brick it, obviously :/. as there seems to be a few versions for the S7
I have the following: S7 android 8.0.0 SM-G930F not sure what else I need to know! I'm in the UK so I assume UK phones come with Exynos cpu's
and as far as I am aware android 8 is Oreo! but when they say Stock Rom I assume they mean the same as what came with the phone the original rom?
if so is there an alternative stable rom without the crap included or is it just as simple to delete every thing you don't want now it's rooted! and does that mean if I reset the phone its back to normal with all the crap included! or is there a way to keep it rooted even after reset! and should anything be disabled I.e prepare the phone before attempting to root like any kind of auto encryption that needs disabling and just one more question
if at anytime the rooting process hangs for a ridiculous amount of time when should I throw in the towel! and what are the chances of retrieving the phone back to original state! or does a dirty shutdown brick it?.
I started the root process but failed at first hurdle!, followed instructions install Odin3_v3.13.1 but when I connected the phone nothing showed up in Odin? though I will have another go just to confirm I followed it correctly, I'll update this when it's done.
this was the tutorial I followed:
Easy 4 Newbie [Root Guide]SM-G930F, G935F, G930FD, G935FD (Samsung Galaxy S7 Edge)
Warning ! Please note that the official TWRP for Nougat on Galaxy S7/ S7 Edge is not available yet but based on my experience the Marshmallow version is working on Nougat. By installing a custom recovery on your S7 and S7 Edge and rooting it...
forum.xda-developers.com
I know alot of questions I would really appreciate any help and clarification on the above.
many thanks

Look pal, rooting the phone is just like being an adult, it means you will get rid of Samsung's "Child Care".
Yes, UK models use Exynos chip, but you have to be sure, look at your baseband version, if it is G930FXXX, then you are good.
ROMs are in two shapes:
Stock-based: These are just like the one you are using, or other Samsung phones does, like Samsung Experience, One UI, TouchWiz. Maybe MIUI and FlymeOS will come into account, as there are ROMs based on them + Samsung's.
AOSP: These are pure Android ROMs, with few modifications to the core, but keeping the UI as close to the source as possible, Google & OnePlus phones come with a near-to-pure operating systems.
Changing a ROM is not risky, as long as you follow the instructions, without any unaccounted improvising.
Before you install a ROM, read the working and bug list, to make sure you are installing something you have an idea of.
You need to install TWRP recovery (or any other one you like), and format data, in order to be able to travel among ROMs and/or root your device.
Formatting is only required because the phone is forcibly encrypted, and TWRP can not decrypt it, at least not for this device.
Rooting is simply about flashing a 5-MB file, Magisk, then rebooting to system, no need to wipe data.
No need to do any additional steps, unless you are trying to hide root from some apps and/or pass SafetyNet.

Before you install a ROM, read the working and bug list, to make sure you are installing something you have an idea of.
You need to install TWRP recovery (or any other one you like), and format data, in order to be able to travel among ROMs and/or root your device.
Formatting is only required because the phone is forcibly encrypted, and TWRP can not decrypt it, at least not for this device.
Rooting is simply about flashing a 5-MB file, Magisk, then rebooting to system, no need to wipe data.
No need to do any additional steps, unless you are trying to hide root from some apps and/or pass SafetyNet.

Hi Mohamedkam000
Thanks for replying. I'm not confused about why I want to root the phone. I'm just trying to understand the inner workings and the risks as I'm not as clued up with phone OS's as I am windows. I don't care about warrantees or hiding the the fact it's rooted I just want a clean rooted phone free of big brother well inside at least I know you will never completely keep them out but making it hard is a start lol.
Thank you very much for all the above especially on clarifying about the roms and the reason TWRP formats due to encryption nice one
My Baseband version slightly different though it's G930FXXU8ETI3 not sure if having a U instead of a third X makes any difference!
and I posted wrong tutorial I'm actually following this one below again not sure if that matters.

It doesn't matter which version of Android you are using, root is the same.
However, on stock ROMs, it might sometimes get rough, as you may end up with Wi-Fi not working (happened to me Q1 2020).
If you really want to learn how Android OS works, then rooting the stock ROM is not your way.
Try AOSP ROMs, preferably start with Oreo ones, you can root in 3 common way, LineageOS SU Add-on, Magisk, Super SU.
But before you tickle your phone, you have to make a backup of your current device, of every partition, EFS is the most important partition, so make sure it is safe.
Baseband version doesn't matter a lot, unless you're paranoid with updates, it is sorted alphabetically, each string on its own.
The phone is more similar to a linux machine than to a Windows PC.
Edit: To root stock ROM, you have to flash dm verity, so you don't end up encrypted again.

Thanks again for clearing quite a few things up I thought rooting stock rom would have been far safer way forward wow how wrong was I! but I guess I am just trying to find any kind simile to windows in any way but as you pointed out again it's more like Linux which again I've only played around with ubuntu and mint for a short period so again not to up on Linux lol.
It's funny I was just reading up on AOSP ROMs then got your message. I see they have a stable but not complete! Android 10 not that I would consider it need as I need a stable OS so Oreo is fine for me.
I have backed up phone using Smart Switch on the PC I assume that copy's every thing that's needed, I reset the phone in anticipation all be it prematurely but at least it restored all my data so if anything that was a good test of the back up at least .
I will have look at some AOSP ROMs and see what's involved there, I'll check out their tutorial hopefully it will include the whole process including root.
I gather by your comment using a AOSP ROM you don't need to use dm-verity or will that still be needed!.
The first thing to do is to flash (install) TWRP, it's a custom recovery (think of it as a mini OS that can boot before Android), that will be the base for any of your future tinkering.
Here is the thread, read the FP carefully: [Recovery][Exynos] Official TWRP for Galaxy S7 (herolte)
Once TWRP installed, you can do many things:
Install addons like Magisk. Magisk is the tool you use to obtain root. Forget SuperSU, its outdated, and don't works in modern versions of Android.
Install a custom ROM (this subforum is the perfect place to find them).
Backup & restore an image of your current ROM (very useful).

AOSP ROMs are pure, you can't say they are not complete. They are complete, and what OEMs do, like Samsung and Xiaomi is just a customization that you can do, too.
It is preferred that when you take a backup, take it with TWRP, just to ensure you backed up phone's partitions, along with "EFS".
The root procedure on Android 6+ is done by patching the Kernel (boot.img), so unless you take backup of that, you cannot keep root.
There are stable custom ROMs, custom ROMs are meant for custom adjustments, however the stability depends on your phone, and the way you use it, you can compare AOSP vs. Stock and see the difference.
AOSP ROMs doesn't need dm verity, well, at least not if the developer did not mention the encryption part.

Some of the roms I have looked at mention external touch buttons at bottom of phone do not work or something else in the phone I'm just reading their comments.
I understand about the stock & custom rom's now that's not my problem at least not at the moment as I am miles away from choosing a rom! as I can't even get out the starting gate!. I can not get TWRP on my phone as the only way I can see to get it on a unrooted! phone is to use Odin but as I said Odin doesn't work at least not for me it does not see my phone. I would love to take a back up using twrp but that won't happen until I find a way to get TWRP on a unrooted phone. what crazy paradox is this!. you can't root phone without twrp installed and twrp won't install on a unrooted phone!. that makes perfect sense.

Does your phone allow MTP communication? I mean can you transfer files when the phone is turned on?
Does the phone show any notification about a usb connection?
If not, then you have probably a bad USB cable, at least, or you have a hardware issue that can go as deep as a burned charging port.
If yes, then either your USB cable is not as fast as the phone requires, or you haven't installed the Samsung USB Drivers on your PC.
Unfortunately, you cannot root your device without PC, at least not since Lollipop.

Hi
Yes I can transfer files.
Yes phone asks to allow or block file transfer and it ohone shows up in Devices and Drives list and I can access the phone directory and shows up as Samsung s7 icon.
I will try another USB lead but the one I'm using is new and wasn't cheap but still a possibility I have had leads that weren't suitable for other things I was trying so it is worth a try.
Thanks

When I downloaded Odin this was latest one Odin3_v3.13.1 though I have doubts that one version update will fix this issue as I did not see many if any people having my issue so they all used Odin and I believe theirs are fine even with older versions! but as I said Mohamedkam it's worth a try I will down load that version and give it a try.
As for the Samsung usb driver I believe that is where I got mine
SAMSUNG_USB_Driver_for_Mobile_Phones no version visible under properties on file version 1.7.23.0.
The USB connection seems to be fine I have uninstalled then re-download and reinstalled a couple of times.
I can transfer files no problem it shows up as Galaxy S7 Icon with card and phone drive inside.
I'll update shortly thank you.
Update:
I just went to try new Odin and whilst checking my phone have seen I have Offical TWRP app installed? I have no clue as to how that's got in there! as Odin did not show phone so I could select nothing!.
In the phone I open app and if i select backup existing recovery it opens and Select Folder tab and under that Selected Folder: /sdcard Filename: Recovery .img and at the bottom of screen Root access required.
I just hope it's installed correctly!. it is showing in playstore my apps as well just to confirm. if this is now installed what should I do next Now not sure what tutorial to start following.
I am just going to try the new odin and see if it picks up the phone back soon.
OK Seem that it now shows up in the new Odin. at least I think it has! in the log window I see this: <ID:0/004> Added!!
I didn't see that before.
Would be grateful if you could tell me how to proceed from here!
Correct, you don't need he latst version of Odin or the Samsung drivers, bit it was just to be sure.
You need to be in download mode, but before, you must have checked OEM unlock & USB debug in developer options (mandatory).
I've written a tutorial with images here (in French):

As I said the older version did not show any kind of data what's so ever and the phone was in download mode. phone displayed "Downloading" which I believe it says that even if it's not doing anything! so a tutorial explained. I think it must have installed the Official TWRP app even though phone did not show up in Odin everything was blank however when I installed the new version of Odin like you suggested it then showed up as <ID:0/004> Added!!. so your suggestion work thanks for that and I did enable OEM unlock & USB debug I did long time ago.
I would check out your tutorial but unfortunately I don't speak French and translating instructions is too risky but thank you for the offer but I'll carry on look around still undecided on what custom rom to go for as I said some comments point out small issues and the developers also state certain things are not working so that is making it hard to consider one if you know what I mean.
Again Thank you for your input very much appreciated.

Take a note that, when you flash TWRP, you have to boot immediately to the recovery, so as to enforce its existence, cause I remember they phone has an original recovery backed up somewhere, and gets triggered when you reboot directly to system instead of the unofficial binary.
I advise you to watch guides on YouTube, it's more .. understandable.

I recommend to go with ALEXNDR ROM: zero bugs, everything works perfectly (it's based on stock ROM).

Important notes for Developers / Chefs !!! This ROM is NOT based on any other custom ROM. My work contains many original ideas and innovations that I introduced as the first in the ROM development (see "Changelist" in post #2). Of course, it...

Yer I read that but I've ended up with TWRP installed and did not do that process because I was unaware it installed until it showed up.
As I said I'll just keep looking for now I know I'll find one that works for me from start to finish.
and I've been checking youtube but wouldn't want to use any links their providing but it may help familurise myself with the whole process if i watch enough of them.
Thanks again for your help.

Hi Mooms
I will check that out many thanks. I wonder if you could help me here. I am in the middle of the rooting process but have hit a snag. again!
I have now installed TWRP successfully then no-verity-opt-encrypt-3.1 all went fine and I'm at point of flashing Magisk but have an issue when I swipe to flash is gives me a error in red saying "invalid zip file format !"
I downloaded it from github here.
GitHub - topjohnwu/Magisk: The Magic Mask for Android
The Magic Mask for Android. Contribute to topjohnwu/Magisk development by creating an account on GitHub.
github.com
I click on "code" tab and then "download zip" and I placed that in a download folder on my sd card when I select it I get the above error any ideas as to why I am getting this am I downloaded the correct file?
thanks for any assistance you could give.
