[Q] Reverting back to your original firmware - Galaxy S 4 Q&A, Help & Troubleshooting

I've just flashed Echoe 2.1.1 rom over my I9505 and later there is a new firmware update from Sammie - MI1. Will I brick my phone if I flash the new official firmware using Odin? Are there any method where you can safely downgrade to your original rom?

You can Flash Stock firmware using Odin I don't see any issues and if u have a nandroid backup of your old ROM that will also work just fine
B4 doing anything if u have not done Do take a efs backup and nandroid backup and keep it safe somewhere on Pc/ Sd card
and after flashing Stock firmware I suggest full wipe / reset for error free experience

thanks for replying but is it save that flash 4.4.2 via odin and after flash will I receive the official update from samsung?
And one thing, after flashing to 4.4.2 I have to root the phone again or not.???
Thing is, odin 4.3 or other old firmware and then OTA to 4.4.2 , or odin 4.4.2 firmware in the first place, it's same process you have to do but with different firmware.
Yes, if you leave newly flashed firmware untouched.
You will probably have to root again.
You can also choose odin flash recovery and then flash pre-rooted ROM to have everything done in less process

You can flash any custom rom you want ie: Kitkat/Jelly bean/AOSP . but you cannot downgrade your phone using odin mate , You need to download a custom rom and then flash Philz recovery or TWRP , Do a nandroid backup and do a fullwipe and flash the rom.

If you want to remove root:
- Use Triangle Away to reset the binaries and system status to official
- Unroot from within the superSU app
- Flash the rom with Odin
- Data factory reset
If you want to keep root:
Use Mobile Odin Pro to flash the new rom and keep root. Check inject superSU, Everroot and the other option.After it reboots do a data factory reset (root will stick btw).

No it's not safe nor recommended. If you had done a search you'd find dozens of threads asking and answering this question in existing threads. Accepting an OTA update is likely to break root and sundry custom ROM features.
You should refer to the custom ROM support thread where the developer will either tailor updates for your ROM. Or at least power users will discuss their effect on the ROM and how to best apply an update to your particular ROM.

OP is talking about flashing a full stock rom with Odin as i understand , not about getting or installing OTA`s as he is on a custom rom atm

Its easy method if you don't have pc for flash via odin or afraid make mistake,
Question here : http://forum.xda-developers.com/galaxy-s4/help
Dont spamming on original devs

A little help, please.

I'm coming from 4.4.1 I want to flash a Lollipop ROM, I haven't flashed for very nearly 2 years. I'm obviously rooted already.
Is coming from KitKat as simple as just flashing a Lollipop ROM? I'm an SM-9005, I've got Odin 3.10 and I want to flash Resurrection-Remix-LP-v5.5.5.
I've seen that I need to backup my PIT and obviously backup my current ROM, do I need to update my baseband or radio etc?
No one?
No need to backup your baseband or radio. RR is an AOSP ROM as far as I know, so you won't be able to flash it with Odin I'm guessing, as it comes as a zip package? I don't have any interest or idea about it, but you can only flash via Odin if the ROM comes as tar image.
Also as you are coming from KK, you 'might' need to flash a stock Lollipop ROM first to update the bootloader from KK to LP, read RR topic, see if its mentioned or not. If its not then you probably don't need to, but as I said no idea.
