Hi. I have installed Doctor's S6 Port ROM in my i9500. I'm having some signal issues so I want to go back to stock rom and try signal. Here's the question. Can I full wipe my device with custom recovery (wipe data, dalvik, cache, system, preload) and then flash stock firmware with Odin?
Another Question. The Stock rom file I have is HOA7 and my current bootloader version is I9500XXUHOA7 and the modem is I9500ZCUJOH2 (this modem came with doctor's ROM). I want to download stock rom HOH4. This stock firmware will upgrade bootloader and flash a new modem? Also, what happens if i have a higher bootloader than firmware. Example, if i have HOE3 bootloader and install HOA7 firmware?

Yes that would be the correct procedure. Wiping with the custom recovery and then flashing rom with Odin.
The bootloaders are not that strict. You can switch freely between Lollipop versions.
If you are having signal issues why not just swap between custom roms? Maybe try a few different Lollipop modems.
Make sure you do the advanced wipe in TWRP.
Doing a factory reset will only wipe /data, /cache and /dalvik.
Select andvaced wipe and select the partitions manually.

Hello! I have installed the CM10 from pershoot whit recovery,modem and bootloader .tar from droidbasement.com. Recovery is able to wipe cache but when i want to wipe data it force restart in recovery and nothing have been erased. Do i can wipe all whit Odin or something else?? :cyclops:
If i format every folder From the recovery on my tablet do i will able to flash original rom whit odin to return to stock or it will break something?
I had these experience as u described.
You likely have to flash any ICS stock rom from Odin and then root your device in order to get this resolve.
Hello,
I'd like to know when I have to wipe my when I flash a new firmware or a samsung based rom for knox 0x0 reasons. Do I have to wipe BEFORE I flash the firmware or do I have to wipe AFTER I flashed the firmware? I don't want to wipe so often and I think one time should be enough, shouldn't it?
For example: I'm on stock 5.0 lollipop. I have to downgrade to 4.4.2 to use Towelroot. Is it enough to wipe my phone after I've flashed the 4.4.2 firmware or do I HAVE to wipe my phone before? If so, why?
Bump. I'd really like to know!
If you're downgrading, then I'll assume you are flashing a tar with Odin. In that case it wipe your phone anyway, you can wipe before if you want to. Not necessary though. When flashing custom roms you always wipe before. You should really google this stuff or search for the info here.
So why do people tell us to wipe the phone if the tar file wipes the phone anyway? For example the Knox 0x0 roms.
It's a good habit to get into
Sorry to start a thread for something that I think is simple. I want to update my S5 to the newest PF4. I was on a rooted 5.0.1 before. I didn't care about keeping root, etc.
I used SamFirm to download the newest firmware. Then ODIN to flash the newest firmware.
The result was it upgraded my phone to 6.0.1 instead of a clean install. In the old days, I recall having to clean cache, clean Dalvik cache, and maybe some other steps.
I simply want to nuke my phone 100%, and load it with the stock firmware PF4.
If I reboot my phone into recovery I see Wipe Date/Factory Reset and Wipe cache partition. I envision that is what I need to do, but looking for confirmation. Also, does the order matter?

You just need to flash a full factory tar from odin
Where do I get a full factory tar? I used SamFirm, the screencap is below.

You can use Samsung smart switch emergency upgrade and initialization option to fully wipe and upgrade your device.
Or just flash the stock firmware, and then go to recovery and do a factory reset.

I'm still on 6.0.1 if I download and install Nougat via Odin will all my data, pics etc remain or get wiped?
if you use your home csc it should not wipe the data (if your region still dont have Nougat use Csc from latest MM ROM in sammobile), if you flash other csc then you phone is on now it will for sure wipe your data. On the safe side do a backup Also worth mentioning that Nougat is a big update and a clean flash wouldn't be so bad After OTA I was going to factory restart my device but now its running very good so decided not to do that Maybe wiping cash in stock recovery did the trick
My main phone got damaged so i am using this Moto G4+ phone temporarily. Years ago i flashed Resurrection Remix Nougat on this and the phone is really slow and laggy right now so I am hoping flashing a stock ROM will fix it but i am not sure how to flash the stock ROM. I know about the fastboot method but i am worried about bricking the phone and i really do not want to risk bricking it at all since this is the only working phone i have right now. I am worried about all these different bootloader versions and the 32bit/64bit thing. My current bootloader version is 1.07. Should i fastboot flash the ROM given here https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138 or do i have to do something else first?
Thanks
If you're worried about bricking your device, I would initially try flashing the TWRP flashable of the Nougat or Oreo stock ROM (from here https://forum.xda-developers.com/moto-g4-plus/development/rom-oreo-8-1-0-soak-test-t3873367 ) This TWRP flashable will update your system, boot(kernel) and modem and should not update your GPT/bootloader (so you'd still be on B1:07). The stock ROM is 32 bit - if you're flashing, I would recommend you wipe data, after flashing, before booting - so ensure you back up (e.g. backup system, boot, data in TWRP) and keep that back up off your device.
If anything does happen, restore your backup and reboot.

I was able to successfully upgrade to stock Oreo through that TWRP zip but unfortunately the phone is still laggy, Do you think that fastboot flashing the stock ROM or upgrading to custom Pie ROM will help?
