Just swapped my moto g for an s3 running 4.3 jellybean. I have no pc to flash recovery. I tried some of those root apks like towelroot and framaroot, no joy though.
I assume with 4.3 a few holes were fixed. I do not know how firmware update goes with samsung, but I was hoping I could downgrade with maybe 4.1.2 firmware which may be rootable with apps like towelroot. Is that possible, to downgrade with firmware on sd card, applying update from stock recovery ? Or only possible wih odin from pc ?
No, you need a pc to do any of that -you can't downgrade before firmware EMG4, even with a pc.

Hello
I had rooted my S3 few days ago with this tool SAMSUNG GALAXY S3 TOOLKIT V1.0 so my phone has now root access a CWM.
Modem version I9300XXLEF
Number version IMM76D.I9300XXALEF
But notification said that there's new update available - 8,91MB installation brakes after restart cause lack of some signed files, is it possible to update my phone now but without erasing any data ?
I have found latest firmware here Samsung-Updates.com-GT-I9300_XEO_1_20120612172415_pax5uhw4id.zip XEO for Poland but don't want to loose any data from phone
Which tool should I use and what files should I use ?
Thank You for any help.
If you want to go back to stock rom why don't you use the Toolkit again? It's pretty straight forward.
Just flash the latest Firmware via CWM if you want to update.
thread: Official Stock Firmware (up to latest)
back-up via Titanium Backup if you don't want to lose your data

I'm still on stock ROM but rooted and with CWM, so there's no way just to apply modified update, or to unroot it with stock bootloader just to do an update and then root it again with CWM ?
@bordikun
Yeah, I have read it but it's full firmware/ROM if I understand it correctly, I got Titanium Backup and use it but just feel that all this is just an overkill, so many procedures just to update 8,91MB of data ?
have you tried there ?

Hello,
I am using a Galaxy S2 (I9100) running Android 2.3.3 that has been rooted with the zerglings method (the one with busybox where you don't use ODIN and just execute the batch file from your computer). I am currently stuck with a wireless mobile broadband connection that wont let Kies update (Gets stuck at "preparing firmware upgrade components"). Yes, I am using the latest Kies and have tried on a different laptop as well.
Now that I cannot have the official update from Samsung, and since I already have lost my warranty, what is the safest way that I can use to upgrade to ICS? And in case I end up bricking it, can I recover it?
Another reason why I am a bit unsure is that I don't want to lose root. I hope I'll be able to retain root and other installed apps (like Droidwall, ES File explorer etc.)?
Regards,
Sayak
Regardless of what upgrade path you end up taking, you will lose root. Sorry.
As long as you find and use a firmware meant for your exact model phone, there is no danger in flashing a firmware with Odin. (unless you do something weird, like unplug the phone or your computer loses power in the middle of the flash or something)
There is a thread on this forum with all the stock GB/ICS roms you need. (Look and you will find).
All you do is flash which rom you need and if you want root simply flash a custom kernel via odin like Siyah.
I've just revived an OTA on my rooted international Galaxy S3.,
It says in the "Update Details" *You cannot downgrade to the old Software after this new software upgrade, due to the security reason.
This makes me think there going to lock my bootloader or something and if that's the case I'll just delete the update and change the phones internal settings so it won't download OTA's.
Recently I've been keeping my phones pretty much stock, a few small tweaks and a few apps that require root,
I'm thinking it will probably just fail the OTA update with the phones status now saying / being modified.
I've also got Mobile Odin installed with enable Everoot, Inject SuperSU and Inject Mobile Odin.
Has anyone been through this ( Int SGS3 Stock Samsung firmware, rooted with chainfires root software - OTA to 4.3 from 4.1.2 if you have how did you get on ??
Any help greatly appreciated.

OTA will fail if you have rooted. If you want to update to 4.3 then best results come from wiping, format internal storage then flash MK6 via odin.
Hi, i am rooted VS985 with king root, installed TWRP and on Stock 4.4.2 and rooted for deleting all pre loaded verizon and amazon apps and did some changes in system folders like hidden menu etc .. all deleted not today when i connected my PC software assistance tool , it says update is available.. see thumbnails
Now, i am confused if i update my rooted device , can i brick my phone?
please someone guide me, should i go for this update or NOT??
If you ran the update through the tool it would fail since you are rooted and don't have stock recovery installed anymore. It's good practice to never update the phone via OTA or tool if you are rooted and/or have a custom recovery installed.
To update to the latest firmware, use twrp to flash the 35B (5.1.1) version of Skydragon, jasminerom, or xdabbeb's in the Verizon G3 android development section. All are stock based ROM's and run great. 5.1.1 has been a godsend for this phone. Much smoother and better battery life.
Hi there. I just broke my s6 and so had to go back to my old s4, heh. I currently have a rooted OC1, and I was looking at the latest info on available root methods and see that the OF1 can be rooted using kingroot. My phone shows an OTA available but repeatedly fails when trying to update.
My question is, should I try to figure out what is causing the failure, update the "right" way, and then root with kingroot? Or should I just figure out another way to get the update, like I think the old way was to downgrade to OC1, root, then odin the OF1 update. Should I just do that?
This happens when you try to ota on a rom which has root or has been modified. Just dont update it doesnt add any features
