I messed up and flashed a Russian 23s ROM. It flashed some firmware that now only allows my single sim x727 to grab a sim signal when it's configured for dual SIM. The other issue is I'm unable to boot latest Omni ROM releases as of last week (4-30+) builds.
I tried restoring to Stock 19s via twrp and OTA update, but the firmware checks it does during OTA makes the update fail. I'm still able to use the phone but hoping I can find a way to completely restore it to stock for x727.

My model number is the SM-N910P. I was on Android 5.0.1 when I first rooted and flashed CM12.1 on my phone. However, as I incrementally updated the CM nightlies, my signal seemed to get weaker over time even to the point where I simply have no service at all. I decided to snoop around and found that updating firmwares may fix these random signal drops since I was still on the Sprint 5.0.1 firmware while running the CM12.1 based on 5.1.1.
I managed to successfully flash the official 5.1.1 firmware from the Sammobile website and thought for some reason the cf auto root file (based on 4.4.4 according to the site) would work with the 5.1.1 firmware. Obviously, that wasn't the case and now I'm stuck in a bootloop. I assume there is no root method that works with the 5.1.1 firmware yet. Is that true? I do believe that was the reason for the bootloop, but I'm not 100% certain.
I'm currently downloading both the 4.4.4 and the 5.0.1 firmwares. Will flashing either of these firmwares via Odin get rid of the bootloop? Or will it fail?
Thank you for the answers in advanced!

So I'm pretty certain the "N910PVPU1BOB7_N910PSPT1BOB7_N910PVPU1BOB7_HOME.tar.md5" is the 5.0.1 firmware file. However, it kept failing so I reflashed the 5.1.1 firmware and it oddly enough succeeded. I believe it kept failing because I actually had it flashed on my phone. I was working on the bootloop fix last night so I didn't keep track of which firmware I was flashing.
I managed to successfully get out of the bootloop after reflashing the 5.1.1 firmware. I will try to flash the 5.0.1 firmware again and TWRP.
EDIT: The 5.0.1 firmware was never flashed. I simply just can't seem to flash an older STOCK firmware ever since getting 5.1.1.
UPDATE: Since I couldn't manually flash an older stock firmware via ODIN, I decided to just go ahead and flash TWRP via ODIN then delete all the dalvik cache/cache stuff via advanced wipe. I managed to successfully flash the latest version of the CM12.1 nightlies and gapps zip through the TWRP install option with the current 5.1.1 firmware: N910PVPU4COG5
Hi,
I am getting a bit lost. I have a LG G2 which I recently upgraded to MM (last stable Bliss).
Before the upgrade I was using Stock KK , that worked fine. Now I upgraded the phone, and it looks like no SIMcard are working anymore. I tried several, they all give the dutch error 'kaartfout' (cardfold). When I check the settings, it tells me no SIMcard is inserted. But it is inserted, and it is inserted the way it should be.
What is going on?
What model?Maybe it was unlocked and with all the wipes unlock was lost?
LG D802 (is that sufficient information?)
I have no idea how to find out if it is currently locked.
Can it help to flash a new radio?
It's because your phone has a kitkat bootstack. What you need to do is go back to stock jb/kk, upgrade to LP -before rooting-, root, autorec, upgrade to the latest twrp and flash the rom. You can also flash the LP bootstack ( instead of going back to stock), but I don't recommend it, as it may cause problems.
Here are the two threads that will help you:

Today after i updated to android nougat I tried to flash with odin firmware (SM-G930T_1_20160704090453_jo3tv4r6ht_fac) to go from 930p to 930u but it failed, and after that my phone doesnt want to restart, when i want to trun on recovery menu it crashes after 5 sec and reboot again, i can turn on download mode and try flashing some other firmware to repair my nougat one. Anyone have nougat fw for 930p so I can flash it and make my phone work correctly, or maybe i can downgrade to lower fw. Please help me and give advice how i can fix this. Nougat was working correctly but flashing the SM-G930T_1_20160704090453_jo3tv4r6ht_fac was a mistake and I ****ed up my phone.
@edit I just flashed it with APJ2 and it is working fine again. We can close this
Was there any other people besides you that had flashed that firmware? lol i would never do that to an 800 dollar phone unless it's a community that flashed that firmware then maybe i would. Try browsing sammobile for the firmware. The software version for nougat is BQAA. Hope i helped.
I've just installed the newest firmware for my J730F with the latest U5 bootloader.
The issue i'm having with it is that any custom ROM i install the SIM card is not being recognized.
Apparently Samsung has made bootloader downgrading impossible so i'm stuck with the stock ROM if i wanna have a working SIM.
Any solutions to this?
I also did the mistake and updated to the latest firmware now i am stuck. Tried to downgrade but ended up being failed. Can anyone help please?
I Keep losing wifi when on stock rom, Custom rom everything is fine , but i gave up trying to get atmos to work. So i want to restore back to stock either MM or Nougat. If somebody could upload a copy of their EU B2017G EDL firmware with the EFS partition i would be extremely grateful. I seem to have lost my backups.
Thanks
QUICK UPDATE
I found a copy of the full EDL backups from a Russian site. I done a full wipe using TWRP then i used my original stock UK MM 6.0. ROM and flashed from inside TWRP. Then used the Russian EDL files to give me Nougat B16. I Think it was flashing the stock rom with TWRP gave me the desired results, I was not getting any luck just flashing the EDL files alone. Hope this helps anyone else out who are not getting luck with radios on stock rom after using a custom rom.
(Apart from this, Its time for a new Phone!!!)
My mobile signal was weak i tried to flash but it was dead
