(Galaxy s2)After Custom firmware, Possible to put stock OS back? - Android Q&A, Help & Troubleshooting

Heya guys,
I currently own a Samsung galaxy s2, which is still in warranty.
I was wondering if after i flash it with a custom ROM of ICS, i was thinking about sticking on Resurrection Remix ics v1.0 PRO.
If it were possible to literally put the stock operating system back onto it, potentially reapplying my warranty?
Cheers in advance guys,
Demonz

Obviously you void the warranty but if you want the root re-apply will have to search the forum on how to install the original firmware

Do you know if there is anyway to take a complete backup of how my phone is now? and if wanted to literally just reload it all back at a later stage?

yup. Odin custom recovery cwm, then make a nandroid backup of the stock image of your phone. Then flash rom through cwm. If u have to rma it simply restore stock backup and odin back stock recovery. No counter trip.

[Q] Question regarding stock roms / flashing

Hello,
Long time reader here. I finally made an account recently because I finally wanted to Root my phone and mess around with Cyanogenmod.
My question is this: I have an unlocked, unbranded Samsung GT-i9300 that I purchased from Newegg back in the summer time and I have still yet to receive any sort of update (still on 4.0.4). Can someone explain to me the whole stock updates scenario? I would have thought buying an unlocked, unbranded phone I would have at least gotten updates faster than the Verizon S3. Now.. I know I can flash Cyanogenmod and be done with it. Which I have which leads me to the last question. What happens if I flash my phone with the 4.1.2 stock rom that was just released in Poland recently? Will it work? Why wouldn't it? Does the baseband really matter as far as compatibility? (PDA? CSC?)
Thank you for your time.
I answered my own questions. Thanks for looking
I was so excited I forgot to elaborate a little.
I was successfully able to root my phone using cf root / odin, install clockworkmod recovery, install cyanogenmod 10 then re-flash back to stock using triangleaway, and a stock rom from samsung firmware using odin.
I had thought I bricked my phone when it was in an endless loop on the splash screen but I was able to get into android recovery mod and do a format/wipe/clean cache. *phew*

[Q] Any Knox free roms for i747m s3

I'm no on android 4.3.1 liquidsmooth custom rom and I need to downgrade back to android 4.1, but I can't without bricking my device apparently because of Samsung Knox. Therefore I'm asking if I can flash another 4.3 rom without knox on my i747m s3 that will allow me to downgrade.
NOte: I need to downgrade because I'm getting very weak wifi reception, I want to see if downgrading back to the stock rom will change anything, any otehr suggestions for tackling this issue would be appreciated, thank you.

hello,
simply flash kriEv's knox-free, pre-rooted stock ROM --> http://forum.xda-developers.com/showthread.php?t=2558311
you may still run into trouble if you try to flash anything based below 4.3.. I would just bite the bullet and upgrade to 442, maybe slimkat or cm11

Issues returning to a custom stock rom after flashing aosp rom

Hey guys,
I assume that someone has previously posted a thread about this issue but my attempts to reach any have proved pointless.
Therefore I hope someone could just enlighten me as to what I could do to solve this issue.
I flashed this aosp rom on my Galaxy SIII (I9300 international) but I decided to go back to the custom stock rom I was previously using but when I tried to restore my backup the phone got stuck in bootloop in the samsung loading screen.
Thus, I tried to flash a new custom rom from the ground up the the phone is still behaving the same way.
Can someone help out, please?
Thanks in advance!
Cheers!
I would advise you to use this rom (its build on touchwhizz but with many improvements)

Just be sure to select the right one

Use Odin to return your phone to official stock... if stuck in bootloop after flashing boot into recovery and factory reset.Once you have your phone up and running then you can go back to flashing a custom rom.

The device is already rooted, you just need to download any custom ROM you want, reboot to recovery, and flash your desired ROM from there.

first of all thanks for your answer.
If I understand properly
therefore, I'll have not any problem because of 4.4.4
that is correct ?
Yes, that is correct. The device is already rooted, with custom recovery, which means you can just reboot to recovery, wipe everything, and flash any desired ROM you want.
@@[email protected]........No disrespect intended, but this is "flashing 101" basics stuff........
The fact that you are asking it, tells me that you don't have the experience needed to do this comfortably.....
That's not a problem though.....we all start from the bottom, and learn as we go.....
But that being the case, i'd advise that you don't do anything to your phone until you've read, learnt and completely understood the processes behind the flashing procedure. It's best to understand what you are doing beforehand, rather than trying to figure out what went wrong afterwards.......

Installing a new rom galaxy s5

Dears,
I bought a new unlocked galaxy s5 G900A 2 years ago. I runs on Android lollipop. I want to delete this rom and install a newer one "either official or custom". I want to ask: " will installing a new rom affect the unlocking; will the phone return locked back to AT&T, or this doesn't have any impact.
Kindly advise & Thanks in advance.
You can backup the stock rom, but this device is no longer under warranty so once you install a custom rom I don't think you will want to go back?
