[Q] GT-N7100 animates SAMSUNG indefinitely

HOW IT STARTED
Yesterday I noticed that my phone was off. I connected the charger and found that it was still half full. I turned the phone on and it worked normally. After an hour I noticed that my phone was off again. I tried turning it on but it only reached the SAMSUNG animation and animated it indefinitely.
A month ago or so I received a notification in the notification bar about refreshment of security policies. Since my phone was rooted, I did not want to apply them because I was afraid that it would kick Knox back in. Then a couple of weeks ago I received a new notification about a new software update from Samsung. At first, I did not want to install that one either. But a couple of days ago I thought what the heck, let's try it and agreed to install it. I left it to install in the background and forgot about it.
WHAT I DID
First I rebooted into recovery (TWRP) and did all wipes. While doing them, TWRP complained that some of them could not me completed. I rebooted and saw that this wiping did not have any effect on the issue.
Then I rebooted back into recovery and did wiping again. This time I noticed that when I ordered a reboot from TWRP, it confirmed me if I was sure because there was no OS installed. I found that weird but had no choice but to reboot and naturally nothing had changed: it still animated SAMSUNG indefinitely.
What else is particular is that the samsung theme melody is cut of in the middle of the animation. When I hear it being cut of I already know: that boot attempt will never end.
Then I downloaded and flashed the latest stock firmware from Sammobile with ODIN. All was well in ODIN but when the phone rebooted, I once again had the opportunity to watch the word SAMSUNG indefinitely.
Then I tried downloading and installing the latest Kies 2 into fresh Windows 8.1 virtual machine and tried the Firmware Upgrade and Initialisation option. It asked for model and serial number and then downloaded something but then said that "This device's version cannot be updated". I then tried Kies 3 but that said that I had the wrong Kies.
WHERE I AM NOW
I tried flashing downloaded n7100_odin_efs.tar with ODIN, knowing that it would erase/overwrite my /efs partition which contains nv_data file with my IMEI code but since /efs could not be mounted anyway, there was nothing to lose. After flashing this file I successfully booted into fresh TouchWiz and saw the information in the attached screenshot.
I checked the IMEI by dialing *#06# and it was "004999010640000 / 01". I don't have a backup of nv_data and I have broken the warranty by flashing custom roms on it. How would I get my nv_data file regenerated with the correct IMEI (without purchasing special hardware or paying some guy with such a box)?
I tried a program called WRITEIMEI which should allow me to write back the correct IMEI but when I tried to read or write with this program, it only displayed "Verifying" indefinitely.
Current problems:
- Unable to fix IMEI from generic to back to what it's supposed to be (to get mobile network access back)
- Unable to get rid of this technical information banner (see the attached screenshot)
- Wifi is always off after reboot

To be honest, if I were you I'll just flash a .pit file to erase everything off the phone (and to erase any errors). After doing so, flash a stock ROM (before 4.3) or a custom ROM, preferably a AOSP ROM. This (might) solve your IMEI issue. (It did for me anyways) (The information banner looks like something from factory mode or something like that, not exactly sure.)

Click "Thanks" if I was of any help!

The issue was resolved by taking the phone to a mobile phone repair service which took €35 and returned the device with a functional IMEI.

Note II LTE stuck on bootloader

Hi,
This morning I woke up to see my phone seemingly booting up but after a few minutes I realised that it was stuck on the boot screen. I can only assume something hardware or software related messed up while I was sleeping and now after reading a few threads I am very scared that my phone could possibly be bricked.
First up, I updated to 4.3 from 4.1.2 about 3 weeks and it has been running fine albeit a few annoyances at the new firmware Samsung deployed. To get root I had to install philz_touch_5.11.2 recovery through ODIN and then go into my new recovery to install root through Dr Ketan's Multi Tool which seemed to work well with no problems, it was quite flawless through the whole update. But now I guess something has happened to my phone and that has changed. When I saw it was stuck, I thought that it would be possible to just reflash to stock firmware and that would fix it. It was working up until the point ODIN got "cache.img" which failed the install. Now, I exited ODIN since it didn't work and restarted my phone and tried to flash the stock 4.3 ROM again. This time, immediately I got a screen telling me that there was "no PIT partition"
(Look at the attachment for the screen, I am new so no outside links)
and now I am getting the message on my phone after restarting "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again." I am now downloading Kies to try this but does anyone have any suggestions or solutions?

Update: I spent the past two days trying to solve this and I'm at a standstill in progress. It seems that my phone was one that suffered SDS with a corrupt eMMC chip so I've lost both my firmware and recovery but I can still get into Download mode. It also seems like I have lost my PIT table and I am just completely unable to flash the PIT file back to the phone for some reason. Does anyone have any ideas on how I could just factory reset my phone or reinstall my partition table so that i can get a simple recovery installed? Please help

Exact same issue!
I know exactly what you are going through!
My phone did the exact same thing back in June. It downloaded the firmware update over wifi, then when it went to install, it restarted to the boot logo, and went no further. I had left it for a number of hours, so time doesn't seem to make any difference.
I've been working on it since the end of July, and haven't been able to find a solution yet.

Yeah, it doesn't seem like time would fix it, so frustrating. Right now I am getting the glass of my Note replaced (it has a slight crack) which apparently voids my warranty when I went into my carrier to organise a replacement. After it's repaired I will take it to another store and try to get it sent off to Samsung, hopefully they are understanding about it and will honour their warranty end as I do believe it was SDS so it would be their fault for using faulty eMMC chips. The only thing I wish I could do it just start over, flash the PIT file so I can just install CWM to see if any of my files are still there. I just want some peace of mind and it seems impossible at this point. I guess it is impossible to flash a PIT when the storage chip is corrupt, sucks to lose all my messages and data, just wish I had a backup in place but it is a good learning experience for the next time I have a functioning phone.

I was lucky having most of my info already backed up. I also had just upgraded another line, so I had a new phone to work with. It just sucks having to switch everything over to a new phone, reloading all the apps etc.

Upgrading Issues on unlocked S6 Edge

Hi everyone,
Recently I have purchased used phone(S6 Edge SM-925F) it was almost in perfect condition for price tag.
But it used be slowing down time to time. I tried to update through OTA, but I got a message like "...operating system has been modified in an unauthorized way...." at the beginning.
Secondly I tried to update via Kies then failed. Then I tried my last resort, ODIN update. Although it shows pass in the end, it stucks in black boot loop. I wiped cache factory reset etc, but no luck.
Finally I found a place to fix. Now it works fine but it shows "kernel is not seandroid enforcing" message at beginning of boot-screen. IMEI also has been changed, therefore I feel very suspicious about my phone's security. I visited another shop. The repairman told me that this phone is unofficially unlocked or whatsoever, never update to never versions.
Is this might be true?
Is there any risk to total brick?
Shall I try to fix it?
Thanks in advance.

SM-G925F Stuck at factory reset, unable to enter the recovery mode and flash firmware

Hello and sorry if this is the wrong category...
It's my first time making a thread on xda.
I've been looking for an answer for the past 2 hours, but I still have a bricked phone... As the title says, I can't enter the recovery mode anymore. I tried to do a factory reset (when I could enter the recovery mode) and the phone got stuck at erasing. Now I can't enter the recovery mode anymore. I downloaded a new firmware from sammobile for the SM-G925F. The firmware works since I used it on an other phone and everything worked just fine. The problem is, when I open Odin and add the .tar file to AP, it gets stuck at nand write and sometimes on boot.img. The phone isn't showing that it's downloading anything (it has no progress bar). At this point I have no idea what to do...
Some extra info that could be helpful:
The phone was bootlooping when I got to fix it;
I work in a kind of phone repair store where customers bring their phones for hardware and software repair. I do the software;
I've installed new firmwares on multiple phones and I never had something like this... Normally some time with google and xda could help me to find a working way to fix the problem, but as I said... I've been looking for 2 hours and the problem is still here;
I'm not a pro with Android and phones. I just like to learn new things and I'm still learning.
Could it be a hardware problem?

Can you show me your phone's download mode image to see where could be the problem?
Also, make sure you are flashing latest firmware, if you are downgrading it - than you will get such boot errors.

*Update*
I found out what was wrong. The eMMC chip was broken.

Exist ROM STOCK flashable via Recovery or TWRP for BlackView BV6000?

Hello friends ... I need your help. More than 7 months ago I already have the Blackview BV 6000. A couple of months ago I was covering a problem in one of the charging pins that until today solved by a technical service, because I could only charge it to the current, but the USB storage mode I took it when I wanted.
The issue is this, almost a week ago I got an update by OTA, which seemed strange to me since I have always had my phone rooted, when downloading and installing the update my phone goes from the logo of the start to the TWRP mode and does not happens from there ... Before sending it to the technical service for the theme of the loading pin try to assemble the stock rom using SP Flashtool, something that did not work out, I already got a mistake (I assumed it could be due to the same problem charging pin)
When I received my phone today with the charge pin completely changed, I put my phone back to SP Flashtool to proceed with the flash, but again I still have the same problem of the error in the program.
My question is ... IS THERE ANY ROM STOCK THAT CAN BE MOUNTED THROUGH THE TWRP MENU? since my phone is currently without an operating system, when I turn it on, it sends me directly to the recovery menu.
I hope good answers ... And I thank you from now on. Sorry for my bad english.
