OK on May 7 I upgraded my Samsung galaxy s4 i545 to lollipop the official firmware on sammobil.com.
but then my messenging app won't send and my phone glitches and it's annoying I tried downgradin back to firmware 4.4.2 NK1 but couldn't I kept getting an error message on odin saying write fail and authentication fail.I couldn't find a way to root,so I can use flashfire to downgrade,if anyone can help me I will be greatfull.
Also the root process I'm not using no Chinese apps no kingoroot.com or anything that can look into my phones information.
Please make sure you clear data, clear cache and dalvik cache and then flash the ROM!! I also had same problem, clearing data and other things saved my day

MISTAKE
Any idea of downgrading to 5.0.2 from 5.1.1. I want to downgrade because, my 3G service has been stopped when I upgrade from OTA to 5.1.1.
Official downgrade via odin is not possible. Either you try to solve the issue on 5.1.1 by flashing different firmwares or you go for a custom 5.0.2 Rom.
never do that because 5.1.1 has updated bootloader which will cause problems if u flash downgraded rom
im not sure if u can downgrade bootloader version and how to do this .... but i think if u downgraded the boatloader u can flash 5.0.2
i have Galaxy G9200 HK
i success downgrade it from 5.1.1 to 5.0.2
1.first i downgrade kernel from 5.1.1 to 5.0.2 (made .tar archiwe with only boot.img this ROM http://rom.shuaji.net/rom/6783.html Pingpongroot possible)
2. Now Galaxy S6 is wiped
3. install from ODIN this rom http://rom.shuaji.net/rom/8085.html ( not working on it pingpong root)
For root need again install pingpong root kernel possible, root and again back to kernel from rom http://rom.shuaji.net/rom/8085.html
USE IT ON your responsibility & IF your phone no start or method don't working .you know how install back 5.1.1 from samsung smart switch!

Sure you can flash this. But keep in mind that Knox will be tripped.

You sure the link is safe? I've tried to use FireFox or Chrome but they both reported "The site contains malware" warning......
I doubt your 3g problem has anything to do with 5.1.1. Check the APN settings or go to a store.

My APN setting is alright. When I purchase this phone, my 3G was Ok but after one upgrade from OTA my 3G problem arises. So I think if I roll back to 5.0.2 my 3G problem will gone.

The update can be the occasion, but it's not the problem. You shouldn't accept your flagship phone to be stuck on 5.0.2. Just contact the shop you bought it form.

I'm also with HK G9200 and actually I want to go back 5.0.2 with pingpong root. Can you upload that kernel and rom on baidu cloud and share to us?

i can't verify account on baidu because i don't have chinese phone number but i have rom
G9200ZHU1AOF1_G9200ZZH1AOF1_G9200ZHU1AOF1_HOME.tar
and kernel from Lřđă SM-G9200 5.0.2 LRX22G.G9200ZHU1AOE4.tar
install first kernel from 5.0.2 it crash system 5.1.1
after that G9200ZHU1AOF1_G9200ZZH1AOF1_G9200ZHU1AOF1_HOME.tar
and again kernel from LRX22G.G9200ZHU1AOE4
now you must in pingpong boot actualisation in program and try root.
and after you success rooted you can back to kernel from G9200ZHU1AOF1_G9200ZZH1AOF1_G9200ZHU1AOF1_HOME.tar
for me it worked and i think you can find this roms on google or baidu.
http://www22.zippyshare.com/v/dj07iRfw/file.html < kernel from "Lřđă SM-G9200 5.0.2 LRX22G.G9200ZHU1AOE4.tar"
with that you need only "G9200ZHU1AOF1_G9200ZZH1AOF1_G9200ZHU1AOF1_HOME.tar" rom
hope it can help you.

Hi
My S6 (SM-G920F) is still on Lollipop 5.0.2 rooted with PingPongRoot.
Can I safe use FF to upgrade to Marshmallow 6.0.1 and keep root without tripping Knox??
I read somewhere (on this forum) that this is not possible but just want to make sure before I decide to update.
If this not possible can somebody explain why - I do remember times when we could use OdinMobilePro and update S4 and keep Knox untouched.
Thanks
No ... You cannot get root in 5.1.1 and in MM without tripin knox !
I have a samsung j700M with 6.0.1 mm version and this locked with password google FRP, already tried all methods to unlock and none of the right and also the downgrade to version 5.1.1 but the error in odin, someone already managed to solve this?
Hi Guys I have a SM N915P and i got it updated on 6.0.1 but i want to iflash 5.1.1 on it. i downloaded the firmware from sammobile but i cannot just flash it Odin Says Auth Fail.
I have downloaded 6.0.1 aswell but the problem is that the version i have downloaded is N915PVPU4DPE2_N915PSPT4DPE2_XAS and the bootloaded i have is N915PSPT4DPF3
just wanted to know wether i should flash this one or it will brick the device? also the device is unlocked and i do not want to lock it again as i have no contact the original owner of the phone.
I have been Doing Rooting and other stuff from years not an expert though but this device is making me crazy, No Root No Nothing..
