hello guys,
here's a list of questions I have compiled which were bothering me since i bought my SGS, hope you take your time and answer these:
What is "root"-ing. How different is it from flashing a firmware on motherboard and installing an OS on to a hard drive?
Does rooting an android device kill its warranty?
Which way is the best and reliable way to root my SGS?
How do I bring back my SGS to Factory state after I root my phone?
Is there a way that I can download the AOSP off the android site and install it on my phone.
I'm with O2 (UK) and I'm required to send blank text to a number. My SGS doesnt allow me to send blank texts. How do I send blank texts? :/
How do I integrate my contacts with the ones from Facebook/Google, when I dont want all the contacts from other sources to be shown in my contacts?
regards,
emc
Quick answers:
1. Root = full control of os ( linux superuser capability) it has nothing to do with flashing firmwares
2. YES
3. search the forum or google for Galaxy s rooting (very easy 10 min max)
4. firmware reflash or
*#*#7780#*#*
This code can be used for a factory data reset. It'll remove following things:
Google account settings stored in your phone
System and application data and settings
Downloaded
5. no. that is vanilla android with no drivers. look for vanilla custom rom for SGS on forum
6. I work for a carrier in Romania so i know : IT DOESN'T MATTER IS YOU PUT TEXT IN IT (just put a letter in it and send)
7.CONTACTS->Menu-> Display options
Hope it helps. Good luck.
thanks, your answers were helpful, but raised a few more question now.
if rooting has nothing to do with flashing firmwares, why does one have to reflash fimware to return to factory state? (can you explain technically?)
I still need to figure out how to setup friends in contacts, I've already enabled contacts from facebook/google.. What I wanted to know is how do I filter people from the list so that I can see only selected of them in my contacts and not all?
-----------------------------------
edit:
just saw that my Kies asked me to upgrade to JM1. should I do it?
If I do it will *#*#7780#*#* bring my phone back to JF3 (default)? or will it bring to JM1

You don't HAVE to reflash the firmware technically, rooting basically just overwrites a few files (generally, the kernel). Technically, it should be possible to simply revert the files to unroot the phone. But the only reason you would probably want to unroot anyway is to send the phone in for service, and first thing they'll do is reflash your phone with a firmware which is known to work anyway.. So you might as well.
In regards to the warranty status after rooting, it's actually a grey area as to whether it affects the warranty. If you flash with the I9000M rom, yes, Samsung probably wont be impressed. It is always better to reflash with clean firmware before returning it to service, but unless there is evidence that rooting messed up the hardware on your phone, it's probably unlikely they would reject warranty. But better to be safe.
I don't think Samsung encrypted the bootloader sequence, and had they been concerned, they would have probably disabled USB debugging within the firmware.
ok thanks ^_^
now a few more questions:
whats a clockworkmod recovery?
whats a samset?
whats an odin?
do you suggest me to upgrade my firmware?
how do i backup my current firmware?
If it ain't broke, don't fix it is my moto . Do you experience any problems with your handset ? Like lags , lockups or anything of that sort? If you don't, then I think its better if you leave it as it is. Just apply the lagFix if you want to, but I see no reason to flash your phone to a different version right now.
I have flashed many phones before (where it was much riskier than Galaxy flashing) But I still didn't flash my Galaxy S , because I simply dont see the need to change to another 2.1. I'm waiting for Samsung to release official froyo 2.2. I suggest you wait for that too.
my phone lags a lot
I share phonix view and motto. If you do experience problems post symptoms before doing something like reflash or factory reset.

Lag can be easely fixed with a patch. You get root and lag patch in one pack. Will try to post a link.

updgraded my phone and did a factory reset, phone DOES NOT GOES BACK TO JF3!
just for your info
that's because u upgraded/flashed a complete new rom which replaced the old one there for factory reset will give u the latest firmware/upgrade that u have installed.
I did something stupid. I used BK package disabler to disable a lot of stuff, including beaconmanager, aaaservice, push service, and a few more which I didn't know the function off. I thought if something breaks after restart, I'll just undo it.
Problem is, I didn't restart.
Then I got an update. It updated, and restarted.
Long story short, lots of settings were strange, like vibration feedback was off, and more small stuff.
More importantly, 2 things have broken: NFC is totally broken, it always makes the sound that the tag doesn't work.
And also, my notification tray is broken. The settings gear, and the down arrow don't work, but the switches do.
No notifications show, at all. None.
I really don't want to factory reset. Is there a way to fix this? I hope so.

Probably should have mentioned I did that, and also restarted a dozen times. I guess the update combined with the off packages broke something?

You need to flash your firmware again.

Yep. But you'll get a working phone...
Well, factory resetting is basically not an option right now. Living without notifications, and nfc is also not great. Is there nothing else I can do? Like re flashing the firmware while keeping app settings?
Reable and odin the firmware. Should keep data, but clean up system

So you know for sure flashing is not possible without wiping? So xile6 is wrong?
Btw it's not a brick right now. It looks like a software problem. And those can be fixed, right?

Of course I don't. Neither do you. I don't know what you disabled, neither do you. No idea what your original firmware was, your exact S7E model, CSC, bootloader, modem, the update you mentioned, what flashing method you're planning on using etc etc. If you know you're keeping it secret. Presume you're not rooted but you haven't said.
The only info you've given is that you bust your phone doing something you shouldn't have but don't know what, and don't want to do a factory reset
Not very helpful.
In short, how can we help when you don't give any info and you admit yourself you don't know what you disabled that caused your problem?
Flashing stock FW will work (99.999% certain). Give more info and maybe it's not necessary, who knows? We're not telepathic.

Sorry I'm not trying to be super unhelpful, I was typing via mobile. I'm on a PC now.
I'm not rooted. It's a stock S7edge from the Netherlands (GSM). The update which caused my device to restart was a security update, I think it had the date Nov 22 or something like that.
The packages I disabled before the update and restart were:
AAAservice, Beaconmanager, Briefing, Email, Facebook, Facebook app installer, Facebook app manager, GEARVR 3x, Health service, Instagram, Kies application BnR, Mmsservice, Nearby service, Onedrive, Print spooler, Remote controls, Samsung billing, Samsung Cloud, Samsung Gear, Samsung Mirrorlink, Samsung Print service, Samsung Push service, Samsung Setup wizard, Screen mirroring, Smartcardmanager, Smartcardservice (those 2 probably broke NFC) UIBCVirtualsoftkey (that broke the home button until I re enabled them), voice service & voice wake up.
Anyway, I guess push service broke the notification tray and the smartcardservices probably broke NFC. So, how might I fix those?
BTW just installed a clean push service apk, didn't change anything.
Reflashing should be unnecessary since the tool works without root and system should be untouched.
If enabling doesn't work I guess you're out of luck avoiding factory reset.

So there's simply no way to fix, in the software, what I did to break it?
Guess I'm never going near package disable apps ever again.
You may ask the developer for an idea...
Due to the sandbox system in Android you simply can't access the areas the apps mess around with if you don't have root. In addition those disablers use Knox..
Hi,
- BK Disabler did recommend all customers enable all disabled packages before system upgrade (OTA)
- BK Disabler is using Samsung SDK to work, it means if you uninstall BK Disabler app, it will reset to default (all packages will be enable). So, try to uninstall BK Disabler app, restart your phone and try to update firmware again!
- If it still not work well, backup all your data (copy to PC, Laptop...) before go Setting -> Backup and Reset ->Reset Factory
Contact with the developer at [email protected] to get more support
I mailed him, basically he can't help ATM.
How do I download the firmware (G935FXXU1BPJG) again? I found basically only this working link:
https://samsung-firmware.org/download/Samsung Galaxy S7 Edge/d804/PHN/G935FXXU1BPJG/G935FPHN1BPK1/
But it's going to take 8 hours.
Are there no official Samsung links? So where do these files come from?
Hi guys,
Yesterday, I installed the official 8.0 update through Odin. Right off the bat, I noticed the settings app was completely broken. I extracted the APK off of another rom on XDA but it didn't change.
I should point out most of the sub-menus available are not clickable, it's just plain text.
Do any of you experience this or am I the only one? Thanks.
How was Odin set during installation? I mean settings, files you used.

First of all - 15 kB/s? You are patient There were better sites to download the firmware from.
Second of all, I think you've flashed home_csc (without factory reset). In situations like this doing factory reset really can help (or try flashing phone again now using csc instead of home_csc). Quite "generic" help I know buuut those things may just work for you.
If you don't want to lose data, you can wait. Maybe someone else can help

I used another link provided by an user on the forum on the mega thread "Official stock firmware". I checked and everything was correct so I assume it is the right version of the software.
I actually didn't flash home_csc. I wasn't sure what that was so I didn't want to flash some weird stuff so I left it out.
As far as I remember, I haven't had these problems with leaked vietnamese rom or with s9+ ports. However, I had this problem with the TWRP bump we had on the forum a couple of days ago but the additional options disappeared after a couple of seconds, not sure what was going on.
Did you fixed the problem ?
Yeah you flash the non-home_csc or do a factory reset in recovery mode. It's the system settings data from previous firmware conflicting with it which can only be fixed that way.
Hello,
Few months ago, when the battery was low (just below 20%) my P9 lite started acting crazy: opening/closing apps, pressing buttons, taking pictures, ... Everything so fast that the battery drained in few seconds. After searching the internet I tried changing the battery with an original one. It didn't change anything.
Recently the situation worsened: it seems that the phone fails to detect the real power of the battery. So even if the battery is 50-60%, it can happen that it starts acting crazy or, more recently, restarting all of a sudden. Then it still works, but after a bit it restarts again and the battery now is drained.
Both before changing the battery and now the problem can be easily solved by charging the phone. Connecting the cable stops immediately the phone both acting crazy and restarting.
Anyway, as you can guess, this is quite a problem if you are outside, even with a powerbank. But these restarst are becoming very frustrating even at home.
Beside this, the phone does work well so I think it's a pity to throw it off...
I've tried a hard reset just few days ago but it didn't change anything.
Is it possible to do anything to solve the problem?
Thank you

Hello,
sometimes weird things happens....
maybe it wont solve but
you can try this :
clear all recent apps,
reboot into e-recovery (keeping vol- & power)
then clear the cache and reboot system..
Test how it work...

Yes, the behaviour is more similar to a malware.
It could be an app you recently installed....
A good change is to re-install your same firmware
or possibly to update it to the latest...
You can use Firmware Finder app to do this,
but beware what you do, a wrong firmware
may brick your device.
It's your choice doing this...
Good luck dude.

Hello! Excuse me I'm not sure I've understood correclty. I've searched for the Firmware Finder in Play Store, but looking at the comments it seems not working in my country. I've tried to search for the original firmwares in google but it appears I can find only modded versions which requires flashing and other stuff I don't know how to do. I couldn't find a guide for real beginners, is there?
Anyway I've recently done the hard reset on my phone so it shouldn't be an app, is it? Is it possible the firmware is damaged even if I never unlocked or done anything special on my phone?
Thank you!

Ok dude, you don't have to worry.
There are many guides on the web in various forum,
especially here on XDA. What is your current firmware ?
I mean the whole firmware ex. VNS-L21C432B504 / VNS-L23C605B393;
You can try doing this in two ways:
1 - using FF and pointing to your current firmware or updating it to latest if possible;
2 - using HuRUpdater.
This method let you flash whatever version of firmwares,
but you need to unlock the bootloader and use a custom recovery (TWRP)(it cost 4€).
Using FF will not cost money, you should try it first.

Hello! Thank you for your help.
I tried to follow your instructions but something went wrong.
My firmware is VNS-L31C432B417, so in FF I've searched VNS-L31C432:
I then pushed the button with the "play" symbol and FF searched for all the six tasks, but it couldn't find any firmware
Did I do something wrong?
Strange fact: searching in the internet for VNS-L31C432B417 I found that, since already 3 months, it is available in my country a new firmware VNS-L31C432B418, but, if I search for updates in the settings section of the phone, this update doesn't show up, saying that my phone is already up to date. Is it normal?

Dude you have the same device i owned.
Don't worry about FF, you simply searched the wrong place...
Tap "Common Base" TAB, write VNS-L31C432 and press on the lens to search ...
You'll see all the firmwares for your variant...
Beware dude, you have B417, it's the latest (for single sim)
and cannot update to B418 (it's for dual sim).
You have to point to your current same firmware.
First thing, delete all the safties (fingerprints/pin/pattern)
and do a backup of all your stuff, just to stay safe...
Make sure you have access to the network and use "Firmware Finder app",
choose B417 FULLOTA-MF, follow the inbuild guide (register the IMEI,
use dns/vpn method). Then go into settings/updates and tap "search for updates"
you should find your update. Tap to download it and when it reaches 5%,
tap pause and disconnect the vpn.
Reactivate the download and complete the reinstallation of the firmware.
Quite similar to THIS GUIDE, just change the firmware with yours...
Edit: I replaced the image because it could not be viewed.
Edit2: re-replaced again the image, still it couldn't be viewed...

Hello!
Sorry I took some time to reply, recently I had to move a lot so I didn't want to take the risk to mess things with the smartphone. Anyway, yesterday I did the reinstallation of the firmware, choosing the VNS-L31C432B417 FullOTA-MF dated 2020.01.13 (I didn't get the difference with the other one dated 2020.01.08, so I choose the most recent).
I followed your guide (thanks!), the only thing I changed is the method: the dns method didn't work so I used the e-recovery mode and it seems that all went well... Except nothing changed. Now, even when the battery is full charged, if I listen to a podcast via speakerphone after a while the phone restarts suddenly.
Is it possible there is something wrong in the hardware?
It's so frustrating because aside from that it works flawless.
Thank you for your help!

Ah yes, the e-recovery mode ... :cyclops:
I had assumed you had already tried it, hence the suggestion for using FF ...
So if after re-installing the software nothing has substantially changed,
then it would be something related to the hardware, honestly I can't tell you.
You could try to bring it to this service point or to a trusted person,
maybe a friend who deals with mobile devices.
Or maybe the time has simply come to replace it with another,
anyway I wish you good luck ...

Hey all,
I am very much willing to wipe my phone to do a downgrade.
I have the OP8 Pro, unrooted (never rooted/never unlocked bootloader).
The scenario I see is - I downgrade my phone to 10.15.13 (I have the INAA modell). I'm sure at some point the phone will check for an OTA.
My question - Is it all possible for the phone to upgrade itself if it restarts?
Meaning, is there a time limit that the update is sitting in the queue waiting for the user to press reboot to install? Or can I just somehow figure out a way to silence the system notification of an update pending?
Not sure if that makes sense but my hope is to just go back to 10 and enjoy certain things that just worked out better for me unrooted vs 11 unrooted until some things are ironed out.
Thanks for your time.
No you would need to initialise the upgrade, unless you have automatic updates on.
You would have seen the initial installation begin.
Least that's my experience of it. The update is stored on the phone so you may also be able to delete it.
Turn off automatically download updates.
I downgraded using the special firmware I found (couldn't find official to do it ) and then installed the official EU/UK firmware straight after with no problem
