[Q] Downgrade - Galaxy S 4 Q&A, Help & Troubleshooting

I know that impossible with 4.4.2 downgrade to 4.2.2 without box. But if I have a custom recovery, is it possible flash a CM 4.2.2 for example? Or other custom rom 4.2.2?
GT-I9505 with stock 4.3

You can flash any custom rom you want thru the CWM , what you cannot do is flash an older bootlader that you have (odin) , custom rom do not have bootloaders

for all roms have a description on how to install and whether it is necessary or not

Upgrade from 4.2.2 to 4.3+ without getting Knox

I am on stock 4.2.2 now, rooted.
I would like to install stock 4.3 or try a 4.4 rom. What are my options for doing this? Is there a stock 4.3 ROM I can flash with cwm that doesn't bring knox and the new bootloader? Is the new bootloader (and knox) absolutely necessary for going 4.4?
stock firmware i get from www.sammobile.com, the questions have been answered a countless times before

If you are still in 4.2.2 stock rom with an Oldbootloader like me Feel free to flash a Pre-rooted BMGA rom from Djembey thread and Flash a Custom recovery and you can flash any Custom 4.3 rom you want..But if you dont give a deym about Voiding your warranty then feel free to flash a Stock 4.3 rom and get your self a Newbootloader and if you wanna flash a 4.4.2 Kitkat leak then you can no longer downgrade to stock 4.3 and your warranty is now void. but you can still downgrade to custom 4.3 roms. Have a nice day.

P.S. correct me if I'm wrong, but I think there are pre-rooted 4.3 stock firmware with no Knox, so you can enjoy stock without Knox. Not entirely sure, you'll have to search it up.
Smack that Thanks button if I helped!
KitKat came in on my OmniROM, running on my Note 2.
Sent from a small country called Singapore.
P.S. Time for school, not much time for XDA

Took a look at the Djembey thread, but unsure which firmware to choose. There are quite a few to choose from... I need the latest 4.3 or 4.4 I can install with cwm without new bootloader or knox.

You cannot downgrade the rom after you have odin flashed any 4.4.2 rom.
But you can flash any compatible cwm/twrp custom roms which are 4.4.2 or newer.
You cannot go back/downgrade to 4.3 roms.
Good luck!

Ur first sentence is right, but the rest isn't.
When he flashed only the Google Edition from Jamal( a custom ROM over recovery) and never the leak before, he got not the new bootloader. So he can downgrade if he wants.
When u flashed the new leak u can always downgrade on 4.3 Custom ROM via backup.

Bootloader JB v KK

I'm on stock android 4.3,rooted with a tripped knox.
Will my bootloader always be 4.3 until I flash official kitkat rom?
Will/can custom KK roms change my bootloader?
Thanks
You have to upgrade bootloader through Odin if you want to flash kk custom ROMs. Custom ROMs doesn't contain bootloader as far as I know.
So yes, your bootloader will be 4.3 until you flash 4.4 with Odin.

There are some custom ROMs that provide links to JUST the bootloader itself, which you can flash by yourself in Odin, without flashing stock ROM.
Thanks for that guys but I don't want to change my bootloader,want to keep it as JB.
I tried a few KK roms and experienced problems with them,was just wondering if it was because I had JB BL.
I need to find a custom rom with JB BL now.................
Thanks

[Q] Touchwiz update

Hey guys i want to know if touchwiz will be update to 4.4.3 or 4.4.4 or any custom rom becouse i have 4.4.3 pac rom but i want to install touchwiz for the camera but i cant do downgrade and there is not any custom rom 4.4.3 or 4.4.4 touchwiz. D:
What are you talking about that you can't downgrade? You can't downgrade official roms to a lower version.
You can flash any custom rom you want. 4.2.2, 4.3, 4.4.1, 4.4.2 etc.

Downgrade to 4.3

I was wondering if I could possibly downgrade back to android 4.3 on my gt-i9500 by just flashing the stock firmware using odin. I'm currently on stock rooted TouchWiz firmware android 5.0.1.
And if there is a TWRP flashable stock android 4.3 ROM, kindly tell me.
Your help would be highly appreciated.
Thanks.

The only TWRP flashable stock ROMs are custom TouchWiz based ROMs.

I heard that, when trying to flash older firmware than the one on your device, Odin fails due to some downgrade restrictions.
Wit that being said, it's not impossible to downgrade. You just have to workaround those restrictions. Maybe by following a guide.
