[Q] problem to switch stock firmwares

hi everyone!
i am using a S5 SM-G900F with this firmware: G900FXXU1ANGG900FOXA1ANGBTU
its the open Europe one.
now if i want to change back to a branded german firmware like G900FXXU1ANH6_G900FDTM1ANH2_DTM
the flash always fails at 99% when flashing the "hidden" ext4 partition.
after that the phone won't get recognized even by Kies and i have to reflash the OXA version again.
back when i had my S3 i could switch firmwares forth and back without any problems.
oh, i also like my knox thingie to stay at 0x0.
whats needed to flash other firms ?
thanks alot already!

What's the status of your KNOX bit now?
How has it not been tripped by flashing the wrong ROM?

Do you have Reactivation Lock disabled?
Instructions: http://www.samsung.com/us/support/howtoguide/N0000002/17296/229710/SCH-N330PWLXAR

knox is still at 0x0, guess cause i tried to flash official stock roms
reactivition lock is indeed disabled and has never been enabled!

ok so far i figured out that i actually need a pit file for any german t.mobile (DTM) firmware.
anyone got this at hand by any chance ?

gonna bring this thread up again cause i think its gonna be the same problems with 5.0
anyone got the right pit file maybe ?

Camera not working.

Hi!
I have this camera problem.. When I open up the camera app on the stock rom I get this "Warning": MediaServer failed. Camera needs restart. I also attached the screenshot. I tried clearing camera app cache and gallery app cache aswell. After some googling and messing with it I got so pissed that I cleared the data, cleared cache and factory resetted the phone. When this didn't work, I flashed the stock rom again with odin, and still having this issue. Please help! Thanks for any help.
EDIT: I got it fixed by flashing the I9301IXXUANH1 version.

Maybe it is hardware problem... Open your phone and check connectors. Also send me logcat when that happens

What do you mean connectors? The camera was working before, I tried some roms, didnt like it, went back to stock now having these issues. (I kinda don't believe it's a hardware issue because the device is pretty new.)By the way, I typed in *#0*# in the dialler and got to that testing area idk what it's called, anyways, I tried Front cam there, and it was working, tried Mega cam and boom: Warning: "camera failed". Can you explain what a logcat is? XP, I am no expert in these things, i'm sorry, and my english isn't the best too.

Ehh, when I first rooted the phone, I made a backup using TWRP, now I flashed the backup and camera works. So firmware downloaded from sammobile.com wasn't good. I had a issue with battery life aswell with the firmware downloaded from that page. I am not blaming anyone just it didn't work for me. Thank you for trying to help @Rox

Samsung used 2 different camera sensors in Productions of phones. Imx175 and s5k4h5yb . some firmwares work for one and some for other sensors. NI* and NJ* firmwares are working for s5k4... And other firmwares are working for imx175 sensors .. There i no firmware that works for both sensors... I sent message to samsung to release firmware that is working for both sensors...

camera not working
Hey, I got the same problem...
I tried CM12 on my S3 neo I9301I and used some camera fix for it (idk why or was it necessary..) and then reverted back to the official ROM (from sam mobile).... Since that my cam has given that error... I'd love if you tell me which rom worked for you...
Also the cam works with custom ROMs, it's not a hardware problem for sure...

Im using stock ( 4.4.2) on my i9301 and i have got camera problem also. When i enter camera i get message" Camera failed" ,sometimes get "Mediaserver failed" . I bought this phone a month ago,and didnt root it. When i restart phone camera works. This error appears once a day.
Rox,imas li pretpostavki sta moze uzrokovati greske u kameri?

@morzafigas Yep, works for me too.

Just want to confirm that flashing I9301IXXUANH1 fixed the "MediaServer failed" errors. Thanks!

I have read about an alternative method.
1. Download the stock 4.4.4 Samsung firmware from sammobile.
2. Boot into recovery mode and wipe date, cache / factory reset.
3. Boot into download mode, and connect phone to pc.
4. Make sure auto reboot, f. Reset time and phone bootloader mode is ticked.
5. Press start, and pray the phone boots.
6. Repeat the above steps.
I can't gaurentee that this method works.

Hello again, i found sm-a300m on sammobile but i cant post links here. It seems thats my device.
In case of doing some damage can i go back to lollipop with some backups?
Thx for response!
EDIT: the same firmware (lollipop) is on tsar3000, can i trust this site?

Don't downgrade. Nearly everyone that has tried downgrading the a3 had hard bricked their device.

Thats really too bad... well, i hope a update for lollipop for fix this issues.
Thx a lot, and i decided not downgrade.
You can close now this thread.

galaxy j500h 5.1.1 downgrade problem

I dont own that device, but i thing this would work:
Flash latest 6.0 firmware with samsung smart swich (PC), enable oem unlock in settings, flash twrp for 6.0 with latest odin, do a factory reset and a full wipe (except external sd an android secure). Then download latest 5.1 firmware for your device an flash it with odin (it will take some time).

You are stuck on Marshmallow

Hai bro,,,
u try this one after flashing offical firmware simply reboot your device into recovery mode by pressing Power + Home + Volume UP and do a wipe data/factory reset, and wipe cache partitions then reboot your device, it will start properly and all problems are now solved,,,,,

With the J500H, Samsung decided to lock the bootloader, meaning you can't downgrade. J500h seems to be the only locked device. Unless someone finds a way to unlock the bootloader then you are stuck on 6.0.1.

u can show me. how to flash with odin (

Firmware downgrade Samsung J500H from MarshMallow with the second loader to LP.
Those who are faced with the inability to roll back to version 5.1.1 are uncomfortable with using their phone.
We need to either use the Philippine firmware or install a custom firmware Belousova.
I found an acceptable way to flash my phone with a stock firmware.
For rollback, we need a four-file stock firmware J500HXXU1APA5 or J500HXXS1APE1.
File BL with the second loader BL_J500HXXU1APA5_CL958143_QB8363487_REV00_user_low_ship_MULTI_CERT.tar or BL_J500HXXS1APE1_CL1011281_QB9453563_REV00_user_low_ship_MULTI_CERT.tar .
Odin.exe.
Please note: these files for the regions: CAC, CAU, SEK, SER, SKZ.
In other regions, wi-fi or a radio module may not work.
For other regions, you need another file for a specific firmware.
If you need another region, write me the name of your firmware.
The process of the firmware I will not describe, it is well known.

5.1.1: https://samsung-firmware.org/download/Galaxy__J5__/zvs5/MBC/J500HXWU1APE5/J500HMBC1APE5/

First update to MM have the some botloader like LP. But next update have other bootloader and you can't boot LP with odin to your telephon.
10:32 And some more - Philippines firmware LP 5.1.1 have second bootloader. You can downgrade from last update MM to LP 5.1.1 very easy.

I found how I can help for you.
You may download firmware from here :"goo.gl/Yk1Byz" and unzip and flash in odin this firmware.
Then if some hardware not working you may download firmware for your region from here:"goo.gl/SdcwhA"
and unzip repeat the flash with odin but with one file firmware.
And If you don't update your telephon to MM you can flash telephon using only this stock firmware. Save it. First file you can delete.
I am sorry - in first step you may set BL for APE1 file from my blog . It have second bootloader for firmware.

Help me with this firmware :SM-J530FZSDROM

So i fixed the bootloop with Odin (installing a J5 firmware of course not for my country cuz i am too dumb (facepalm) ) and i searched on my box and it says that this is my firmware SM-J530FZSDROM but i can't find it anywhere...
Who can help me get it ?
Thanks
(Btw. I have a system *only system partition* backuped in my sd card i tried restoring it but it was the boot loop again.. it has 2 gigas idk..)
Ps:forget the system backup i just want the entire firmware xd

What device do you have? J500 J510? Are you trying to go back to stock? And did you also enable OEM Unlock from developer settings? This will cause it to fail at aboot.bin if you haven't.

He has a J530 and if you read his post you would notice that he already flashed something over odin, so he has his OEM unlock ticked.

Well seeing as though he hadn't specified the device he was using I thought it would be a good suggestion to check he was flashing the correct firmware in the first place, I've got a different country for installed on my J510FN and do t have any bootloops.
BUT yes I do know that device names are inside the firmware name.

My original firmware was SM-J530FZSDROM but i flashed with Odin the firmware SM-J530FXXU1AQF5 , i think its from Romania and yes the sim is working so that's the important thing i think.
But i still want the original firmware ...
Questions: Can i repair Knox?
With what to root safetly (to work with snapchat) ?
Thanks guys!

One more thing
And guys when i installed the TWRP with Odin , it was showing this errors : E: Error Grab/Realase and 2 numbers idk
I installed magisk partially with it because it wasn't working with Freedom (Please allow acces to system partition this was the error i got in Freedom) . After that before i got the bootloop i tryed installing magisk again from twrp and i got stucked in bootloop . Who could help me install root and twrp succesfuly ? Thanks.
The first question remains active: Who could search the firmware and give it to my i would owe him.

Click to expand...
Click to collapse
You can't repair knox after it was tripped.
If you want your root to work with snapchat root with magisk or superSU with xposed modules for hideing root

Can you give me a link of supersu like installing without twrp , thanks. For SM-J530F
