Can't Downgrade from Gingerbread to Froyo Samsung GT-S5570 - Android Software/Hacking General [Developers Only]

Hi,
I tried several times to downgrade my firmware Gingerbread to stock Froyo rom but the process end up with a black screen. What is the exact procedure to Downgrade?
My current firmware version is Gingerbread S5570XXKPJ and want to go back to stock firmware.. can anyone recommend me a froyo stock firmware. I tried a one pac installation firmware name S5570DDKC1 and did not workout.
Help me plz

Ive seen with several phones you're unable to downgrade from certain roms and are advised to keep your backups before you go to GB because the only way to go back from a GB rom to a froyo rom is to restore your backup.

try like this: download S5570XXKB1, flash it in Odin...if it doesn't work you can try to use ClockWorkMod to format /system and then it should work...

Thanks a million for the reply guyz... i did figured out by my self.. Actually downgrade does not support flashing one package installer. It requires multiple files flash like, Modem,CSC, Code and all those flash components.
am now using froyo successfully

how did u do it I have the same issue

[Q] Help with installing roms from stock

Hey guys,
I'm relatively new to playing with Android roms, and currently have a HTC Sensation.
I've worked out the kernel that I want to use (SebastianFM Overclocked kernal), the rom that I want to use (AndroidRevolta - slimmed down Virtuous Inquisition) but I wondering about the firmware. My phone is current unrooted, running stock ICS. Do I need to upgrade the firmware before I can flash this rom?
Thanks
to install another rom firstly you have to be rooted
secondly if you want to flash a firmware manually you have to be S-OFF
now about the rom you want to use i think as far as i know requires the latest firmware

Yeah, I know that it needs to be rooted first.
I've just seen things that say you need the latest firmware to run ICS, and I wasn't sure if that came with the offical ICS update.

Yes. Firmware is updated with latest ICS update.
If you have latest ICS update then you dont need to flash firmware again.

Is the firmware flash only for phones that don't have an offical ICS update?
So I can just root, install CWM and flash kernal and rom?

[Q] Rom Stock HTC One Mini

I need to flash stock rom ( Vietnamese version) to my HTC One Mini because it got stuck when i update ota 1.32 version :crying:. Please give me a link to download stock rom for the newest version in VietNam. I'm not sure whether or not to flash the stock rom from other regions
I don't know of any roms with Vietnamese built in, but you can use MoreLocale 2 to download a Vietnamese language pack (the screenshots look dated, but it works just fine).
About roms
I mean that whether or not i can flash roms from other regions without problems. If you have a newest version stock rom, please give me.

If you just want a stock experience you can do a factory reset by powering the phone off and then holding the power button and volume down buttons at the same time till you get to the bootloader screen and then select factory reset.
If you want to flash a different rom it should work, but you might have connectivity issues so just make sure to make a nandroid backup before in case anything goes wrong. I'd suggest Jmz's Stock Rooted DeOdexed WWE Rom. Uhm... once you unlock your bootloader your /data partition gets erased so you won't be able to download an OTA, but I'm sure they'll figure out a fix for that in the future.
Roms
I know that i can factory reset but i desire to update to the latest version through flashing roms. However I have a huge problem with OTA, it sucks

Custom Rom or The official Marshmallow update?

Anyone can suggest what upgrade I should choose and which one is more stable? I want to root my phone as well so if anyone with the official Marshmallow update can give me a good reason to upgrade from 5.0.2 I'd really appreciate it.
Besides sense 7 is there anything else to look forward to in Marshmallow for HTC?
Also anyone with the Marshmallow GPE Rom or Viper M8 please share your experiences with the roms.
For the first time I'm having trouble deciding what to flash on my E8 thanks to all the devs!
I tried everything, and - offical 6.0.1 is better choise. There is best camera. They really updated drivers or libs, i don't know. Stock ROM + custom kernel it's always good. All custom ROM's here is based on older firmwares.

How did you Root and get the custom kernel (without the system write protection) on Marshmallow? Same as how you'd do it on 5.0.x?
Yes, my 6.0.1 rooted, but custom kernel not exist this time. We waiting.

Would you please explain how to root your E8 6.0.1? I prefer to get just root without installing custom recovery, so I can backup stock recovery using flashify just in case for future OTA.
i dont know about way like this. In future u can extract stock recovery from OTA package, that u gonna receive. This always works.
I've flashed supersu 2.67 via recovery.

I received OTA and installed it directly. I forgot to backup the OTA file first so I don't have a chance anymore to extract the stock recovery. I tried to downgrade to 5.02 but always failed.

Downgrading is easy. You need to flash TWRP recovery via fastboot. Do not need full root. ERASE everying. The flash lollipop RUU via external SD.

I have M8SW and it is S-ON, it currently running BinDroid ONE V1.3.0 Android 4.4.4. I'm thinking about trying marshmallow ROM but I've read that is hard to downgrade to Kitkat once the firmware has been upgraded to higher version. But you said above it is easy to downgrade, can you please provide me with the steps to downgrade from marshmallow to kitkat rom. Thanks

Hello!
I need some help on restoring the stock ROM onto my SMG920F. I have tripped Knox using CF-AUTO ROOT. This ended up breaking my phone. So me being me reset it back to factory settings and Installimg twrp recovery.

I would like to have an unrooted and stock SMG920F rather than a routed one :/ can you guys help with that.
My current ROM is nemesis

but if Knoxx is tripped, its forever...
Hey! I have found a website that provides stock roms. I have installed one and my phone is factory new. I even get OTA updates and everything is official. the only thing about my phone is that i tripped knox lol. the website is
updato
I then found a "how to install an officialsamsung stock firmware using odin" and followed that guide
The rom I downloaded and flashed using Odin is here (just copy and paste this at the end of updato
firmware-archive-select-model?record=583A76F4915811E89F15FA163EE8F90B
the way i did it was wipe the usual stuff when you want to flash a custom rom but instead you use the stock ROM. only down point is that it puts your recovery back to stock to. So if you want twrp again just flash it and it should be good to go
if i could post links i would so if you want them then message me and i will link things to you.
Yes I just answered my own question. A thanks would be appreciated
