Here's the story
1. this phone wouldn't boot up after the OTA update, the screen read "firmware upgrade encountered an issue.
please use software repair assistant & try again."
2. used odin 3.09 to reflash pit and the latest nc4 official firmware (I know it can't be rooted, but that's the only choice I have).
3. phone came back alive, worked for t-mobile and verizon sim cards.
Problem:
after a few hours or maybe a day, or maybe a restart, phone won't detect sim card, baseband version shows unkwown, hardware
version is empty, imei, network, MIN, PRL version, ERI version, imeisv, iccid are all "unknown".
What I have done:
phone will be back to normal if I flash the firmware again, I've use odin 3.09 and kies 3 many times.
I also tried flashing different modems, for ex, MI9, MJE, NC2 even NC4. But phone will keep restarting, sometimes the phone is working after
a few restarts. But eventually I will have the same problem again.
I was wondering if someone could point me to the right direction?

When you flashed the different modems, did you check settings/about the phone to verify that the modem flash " took"? Recommend entering Odin from power off, especially when flashing modems. FWIW, I'm not at all sure this will fix your problem, but it's worth a shot.

Yes I did. The baseband version showed MI9 when my phone was still working properly.

OK. Hopefully someone else will chime in with some suggestions.
one more thing I've done many times so far is, sometimes a full reset will bring it back to normal too.
settings -> backup and reset -> factory data reset.
I don't mind bricking my phone, but maybe someone knows other possible way, say, flashing EFS? I don't even know what that is.
I've been searching for the right solution but I haven't found one yet.
Never ever give up!
I'm the OP and I finally got it working. I simply ran EFS Professional v2.1.73, did a backup and restore of the EFS. That's it!
Did you figure out what efs is?

It didn't last long, and using EFS profession for EFS backup/restore never worked again.
I then saw this page the other day,
http://forum.xda-developers.com/showthread.php?t=2610757
So I used odin to flash
pit
official kitkat rom
I also checked these two,
erase nand
erase EFS
the phone booted up fine, I then turned it off and entered recovery mode, did a data and cache wipe, then booted up the phone again, that brought back my imei, my sim card worked again.
Unfortunately I'll lose it again once I flash a custom rom, or perhaps even a reboot.
I'm still searching for a permanent solution. But at least now I can use my sim card with a stock rom
Rom based on which region?

Can you please tell the stock rom based on which CSC ? or country ?
I'm having the same issue. Lost baseband and imei, but never got it recovered. even with stock.
I use this one,

Same boat brother, this is what I've posted. So far I'm a week in this situation, battery pull brings it back, any mod like Xposed with module where you have to reboot looses the baseband, IMEI etc. I have backup of the EFS and restored it multiple time with no joy.
Need some advice guys for Verizon my Note 3, I'm currently stock NC4 ready to. flash this bad boy ROM, after root access with TowelRoot, installation of BusyBox and Supersu no SafeTrap yet. Once I reboot in this state, I have the Baseband unknown under Settings-About Phone status all unknown info on IME etc etc. Off course I loose 4G signal all together. I may reboot again and it comes back. I know about EFS partition corruption and have multiple backup of My note 3 EFs partition. Even with restore it would still happen. I have exhausted all my knowledge learned throughout the years from you guys. But, I'm asking some help again. I am very familiar with all the terms about flashing/rooting so please feel free to throw some genius on how I can fix this thing.

Hello,
I've got (had) an SM-G900W8 running the XtreStoLite v2.0 LP BETA5 ROM on the XXU1BOA3 kernel. I installed TWRP 2.7 via Odin, and left the latest modem and bootloader updates I got through KIES3.
At which point I got the chance to sell the handset on Kijiji, provided I could get the stock ROM back on.
I downloaded the latest Odin (3.09) and the correct Firmware for my handset from sam mobile, and factory reset the device. I pulled the battery, let it sit, and tried to flash once I got it back up in download mode, and it wouldn't work.
This isn't too much of a surprise to me, because since I flashed TWRP, Odin hasn't ever worked for me. Regardless of how many times I've tried to flash the modem and/or BL that XtreStoLite asked me to use in their how to thread, it wouldn't work. I was willing to ignore it b/c the ROM worked with the modem and BL it was running.
My problem is that once I tried to reboot, the system hung at the BL animation. I went back into recovery, and tried to move my backups off my external storage (I had 2 back ups that were about 2 or 3 gigs each, too much for the local storage) to the local card and restore (b/c TWRP won't restore from the external card) and the back ups failed.
Now I've got the BL screen, but it won't advance to the animation, and it won't boot to TWRP either.
I tried to restore from KEIS, but it says my device isn't supported by KIES 3 (it is). I could really use a hand here. Every time I try something this gets worse. I'm no pro, but I've had no problem figuring this out on my old HTC handsets.
Sir,
Please wait until mods will move this thread to the device specific forum for more relevant answers.
Stand by
Good luck
Bought a 'new" Note 4 and right of the bat, I rooted the phone, flashed a custom rom, followed instructions one by one, last time I did this was 2 years ago. Everything was great, but wasn't able to call or text on a Sprint network, but had LTE/3G data.
I downloaded the stock firmware from SamMobile, cant flash it with Odin, it crashes right away with some error "BEX". So, copying the firmware to my sd card and installing it thru TWRP or PhilzTouch, instantly crashes, says install aborted and when it reboots, the Samsung powered by android is displayed and than keeps re-booting about every 10 seconds.
At this point, I at least want the phone to run stock. But is much harder than I thought it would be. IS there something im missing or not doing right?
Hello world, I have a problem with my phone, I'm gonna try to explain it exactly.
I had the 4.4 android version for almost two years, until yesterday (yep, I've been so lazy that I didn't touch my phone for that time). I was tired of being unupdated, so I took my phone and I connected it to the PC via USB. I downloaded the last spanish available version 'Spain (PHE) PDA. G900FXXU1CPEM CSC. G900FPHE1CPE3' because I'm from there, I did the essential wipes and I flashed it via Odin, and that was all. After that the phone wasn't working good (I don't remember exactly what happened after that) so I reflashed it again then I flashed both files: BL_G900FXXU1CPF3.tar.md5 & CP_G900FXXU1CPE8.tar.md5 because I thought I had to upload too the modem and the bootloader. After that the phone wasn't working well neither. I think I reflashed the last stock rom then a combo modem/bootloader I downloaded from the Phoenix ROM, then I flashed Chainfire's autoroot and last TWRP. When I restarted everything looked fine except the yellow message on top at the intro "SET WARRANTY BIT: KERNEL". I read about and the phone run every time, so I thought I had to be used to it, that's all. When I started to clean bloatware I deleted some apps (nothing special, just bloatware) and I removed every KNOX app, because I don't care about it, first day I got the phone I set KNOX to 1 because I didn't know about it and now I don't have any warranty anymore plus everytime I have a problem I solve it myself or with your help.
Now the phone is stuck at the boot, with the SET WARRANTY BIT: KERNEL" and it doesn't go further. Can you please help me to flash the last rom, the one I told you, with its proper bootloader, modem, etc? I just want a clean PHE 6.0.1 stock rom for the moment (rooted and with TWRP too, of course). Thank you.
Try flash rom with odin first(ap),after bl and cp(bootloader and modem (latest from the alexndr 's thread where he upload the latest one )after that when it finish if you stuck at samsung boot animation for long time try boot in recovery and do a factory reset and format cache.
I have only used stock roms on this phone. I originally upgraded my phone from a UK carphone warehouse rom 6.1 (B2017G UKV1.0.0B01)? I think?? That was a few years ago and upgraded to Nougat using the methods used in this forum.
I found that the wifi would sometimes disappear from the phone and you would have to reboot the phone to get wifi working again. That is ok but after about 3 times of having to do this over a period of a few months it would go again BUT then would then need a factory reset to get the wifi going again! After a year of doing three factory resets
i tried to revert to the older MM 6.1.
I used a ROM that i downloaded from here when i first done upgraded
anyhow i placed ROM in SD and proceeded with the downgrade it went fine up to 81% then got stuck then i restarted the phone again and it got stuck again, so i tried to flash from the SD in recovery mode instead and it says "sorry you can`t sdcard upgrade" so i then pressed reboot system and then it just hangs a the logo.!!
I have rooted phones in the past my last was an LGG2, and a brilliant tool was available so you could flash any stock rom back onto the phone if you had any trouble with custom or stock roms. but there does not seem to be any such tool from ZTE.
If you can help in any way?, i would be delighted!!
THANKS!!
(Soz if i posted in wrong area!)
I got the phone booted through EDL and EDL tool & backup files provided by this site. It took me a while to find all the info i needed.
Also renaming the files from boot to boot.img etc in the edl folder took a bit to work out as the tool kept telling me the files were insufficient!
All good now managed to downgrade to 6.1 UK ...Thanks XDA!!
