Note 7 SM-N930F Need to donwgrade - Note 7 Questions & Answers

Hello!
I just got another Note 7 phone that I am trying to rescue and make usable for me.
I got used to HydraRom 1.4.5 on my primary phone.
The phone I am trying to rescue is SM-N930F.
It has SM-N935F ROM on it, some useful info:
Firmware: N935FXXU1AQI5_XDAVN_STABLE
PDA: N935FXXU1AQI5
Baseband: N930FXXU3BPL1
The phone has TWRP 3.2.1-0-gracelte on it.
I tried to flash HydraRom via it, I suceeded but when I turned on the phone and put my SIM card in, on every restart it says something about SIM Update...
I Have IMEI and S/N on the HydraRom so EFS is not corrupted. I am able to take calls on the phone and messages. But the connection is only 3G/H+, on the Note 7 FE Rom I wrote above LTE and everything works fine. On the HydraRom i can´t access LTE or it still says SIM update.
I tried to flash FULL firmwares BL+AP+CP+CSC N930FXXU2BPI7 which work fine on my primary Note 7.
But ODIN fails to flash BL because of it is downgrade. It fails on param.bin and phone writes SWcheck rev fail.
So for the right functionality I tried to load HydraRom via TWRP and then only CP+CSC which ended by null IMEI.
After my last experience I made whole system backup including EFS so when I restored everything works fine on the Note FE rom.
I am now little bit afraid of flashing because at some point phone could not be booted up or TWRP had problems with unmountable data or extractTarFork() process ended with ERROR: 255
Can you please give me little help how to have: Working HydraRom, with LTE, OK IMEI.
Donation to your PayPal for sure.

It is easy to downgrade for N930F,l. Just flash a combination and then you can flash U1 firmware.

I solved my primary problem with no LTE connectivity, but not with flashing combination, just by reflashing another official ROm then installing HydraRom, thank you.
But I have another little problem.
I have many Note 7 phones home and when they are turning on there is Black font on white screen. After that Samsung logo animation starts to appear.
When I was installing HydraRom i ticked by mistake to replace bootanimation by HydraRom.
I would like to have stock one. But his can´t be done by reinstalling the ROM because there are two possibilities: keep the current animation or install HydraRom animation.
I tried to copy all bootnimation .qmg files in system/media/ from phone with original bootanimation to one with HydraRom animation, it does not make any difference. I replaced files with root explorer and also tried with TWRP file manager.
I also tried reinstalling whole AP via ODIN and installing United States ROM, odin passed and ROM was installed OK, but whole problem was that the bootlogo was still there.
HydraRom Shows instantly after pressing power button.
That logo appears also when entering Recovery or download mode. Whole AP was replaced and didn´t replace the logo.
I want to have that Note 7 in best condition for future, as I want original Bootanimation and so during system startup.
Can you pelase tell me where to find those files and how to replace them? Or do I need to replace Bootloader via ODIN?
Thanks

I solved this problem, developer answered me that it is not about bootnimation but about splash screen. So I reinstalled stock one via HydraRom but this was also possible to do by reflashing bootloader via odin.

mobile data/bricking help

Hi I'm having trouble with my bricked M9 and flashing RUU.
I have a Hong Kong phone, using it in Australia however mobile data keeps disconnecting, it'll work for a few minutes and disconnect. I tried the sim card in my old m7 and the mobile data works fine, so I assume maybe because the phone is a HK one so mobile data doesnt work properly. Tried to flash android rev rom but mobile data still didn't work, while flashing another rom I used twrp to wipe cache etc, however for some reason I decided to use the advance wipe, checked all the options and press wipe. As soon as I did that I lost the ability to make calls as well, when I rebooted the phone it booted fine into the new rom but it says limited service and emergency calls only, I swapped the sim into m7 and it worked fine..so I thought I've stuffed up my phone with the twrp wipe or maybe the modem just died.
Since then I've tried flashing back to android rev and leeroids but without success. Tried going back to stock. Downloaded a m9 HK RUU and renamed it to 0PJAIMG.ZIP, put it on a fat32 32g ext sdcard, and boot into download mode..flashed but it gives an error 'failed -2 19: fail to flash via downloadzip'. I've checked the file name making sure is a zero and not an 'O'
Read somewhere you may have to relock the bootloader first so i did and now i can't even boot to recovery mode..since then I've tried fastboot but it gives me an error: cannot load '0PJAIMG.ZIP'
any ideas? the phone reports firmware as 1.40.708.9 and S ON, will S OFF help me? Is the modem broken? Stupid me I should've taken the phone back instead of flashing a rom..now my warranty is void. :laugh: Thanks for any advice.

Does the phone boot into a rom fully?
If so open the dialer and scroll almost all the way down, hit the only open option and choose the correct option for the sim provider hit home twice reboot

N7100 corrupted IMEI issue - please read and help

Hello.
I received this device as a dead device. It would boot until half the Samsung logo and freeze.
Since it's a giveaway and I didn't know about the Note 2's specific EFS/IMEI issues, I just downloaded and flashed the newest firmware.
I then got out of factory mode using terminal commands (from a thread on the same problem with S3 mini) but am stuck with 0049 IMEI.
I at no point did a backup of this device's old EFS and IMEI.
Is there a way to save the phone? all the advice I saw so far refers to people who begin the process by backing up the old EFS.
Can I make the phone work without an old backup file?
Just tell me if it's salvageable or it's a nearly functional brick
thanks!
PS After flashing stock ROM phone also had the "factory mode" label and would shut down with a short press of power button. I flashed AICP v 6.0 before trying to reflash stock with ODIN correct for my region (Israel).
IMEI has been 0049 ever since phone first booted up (prior to me succeeding in booting it, its stock recovery had the "E: couldn't mount /EFS" error message), on first stock ROM (N7100XXUFPF1_N7100FTMFPE2_N7100XXUFPE2),
AICP,
and second stock ROM (N7100XXUFNJ1_N7100OJKFNJ1_N7100JKUFNF1).
Current modem is Modem_N7100XXDMG1
Please advise.
I have read Dr. Ketan's threads, but found no solution. My logic says what's the point of backing up a faulty EFS file, which seems to be what I currently have. I would appreciate any help

Note 7 possibly bricked

Hi all,
so im coming here to ask you for a help.
Yesterday i have read about samsung pushing deactivating update for our notes 7, i have panicked and immediately started with installing TWRP, HydraRom and root to block incoming updates.
But, as i have already found out, my skills with android and flashing are already gone. So i have installed twrp, then rom and tried to reboot but phone was showing a lot of error messages and notification about low memory, which is weird. After couple of hours of seeking i have found out, that i should try to fix /data and /storage in TWRP by converting from EXT4 to ExFat... So i tried it, but phone suddenly died when it was repartitioning and now im stuck with note which is unable to boot or go to recovery. I can get into download mode yet when i try to flash anythin (whole rom, just bl, TWRP) odin shows immediately FAIL!
Does anyone know if there is way how to fix my note 7? I was thinking maybe a PIT file would help, but im unable to find one...
EDIT: Tried methods found here http://forum.xda-developers.com/note-7/how-to/fix-samsung-note-7-snapdragon-exynos-sm-t3443753 but no luck, same story with smartswitch as Odin, flash begins but immediately fails and note comes out of download mode.
So I have made decision, that I will add bounty - 50 bucks (will pay through PayPal) to anyone who will find way how to make my note work!
You should return your Note 7 to Samsung. Its safer and if want to do trial and error. I've found it possible to rescue any phone as long as you can put it in download mode ?
Sent from my SM-N930F using XDA-Developers mobile app
I know i should return it, but i really want to keep it atleast as a second phone, anyone has a solution please ?
Before trying to install twrp and custom Rom what firmware were you on? If I were you I'd download the stock firmware from Samsung site open Odin and put phone into download mode I'm sure that will work.
I was on the newest one, with green battery indicator. I have already tried flashing official rom downloaded from sammobile, but odin always only states fail! After a second, meanwhile phone leaves the download mode and gets stuck on bootloop.
When I try to entry recovery phone gets stuck on TWRP screen but doesn't actually start TWRP.
I will send 50 bucks through PayPal to first of you guys, who will lead me to the successful repair of my note!

Note SM-N930F boot loop Hydrarom

Hi All,
Sorry for my English, it's not my language.
I need your help because I think I have bricked my Note 7 after trying to install the last Hydra rom 1.3.5.
I explain you the situation:
I have installed custom TWRP => it was good
Then I have rooted with superU => it was good
Then I have tried to install hydra rom => the installation was OK
The phone reboot at the end of installation => phone stay on start screen "Hydra rom" and reboot (loop infinite)
I cannot power OFF the phone.
I cannot go to the recovery menu.
I can only go to the download mode.
So I have tried to re-install TWRP with ODIN but it was not working. Ondin detects my phone and when I click on start, I have the message "Fail" on ODIN and the phone reboot.
Do you have any ideas to help me?
Thanks.
Note 7 Problem - please help if you can, please
Hello
I am newbie here with no proper experience [ I flashed mobile with success once but it was years ago with NOKIA e90!]
I have Note 7 exynos UK VODAFONE and I did flashed it with older OEM firmware [ to bring it back to 100% battery], I downloaded from sammobile than recent one on my mobile [ limited 60% battery]
I unchecked re-partition
I used AP file there
all went fine with ODIN v3.11.1 all pass !
but once mobile started I have big message on my screen which does not disappear [ see attached photo]
unfortunately, the process
com.android.phone stopped
I can click/press OK on screen below that message, but it reappears again and again
I tried to flash it again but now ODIN says fail and something about PIT
I would appreciate some help or tell me what steps I should take [ apart of surrendering phone to place I bought it from!!!]
regards
M.
What I did to make this work:
1 install TWRP
2 whipe format data "yes" x3
3 advanced format everything except external storage
4 reboot to download mode
5 open Odin on pc flash BL/CP provided in original Post of HydraRom
6 install HydraRom via TWRP
7 follow direction installation process
8 wait 5 mins boom!
Never fails for me.
I did that. I have already did that several time before. But I think I have understood the problem. My BL file is corrupt (may be during the download from the server)!
So I think the boot loader not working correctly! I have tried to reload one but without success. Directly Odin write "FAIL"...
Able to access Download mode only after Hydra flash. Solution?
Did this issue ever get a solution? I am having the same issue. I can enter into download mode only after the attempted hydra flash. Now it's stuck on "Hydra N7" boot screen. I had N930F flashed and running with twrp. When I attempted hydra I believe that the full rom did not flash, only 40 MB or so. To make matters worse I can't find where I jotted down my baseband, etc. It was originally N930X (live demo model). Now I get fails in odin. What can I do to remedy my situation. I read that I should flash BPH6 base files, but here it says AGO or AG2 BL. Which is it? How do I wipe the cache and data since I can only access Odin mode? I believe my BL is corrupted. Please help. I was going to trade my Note 7 in but my imei is all zeros and the boot loop. I'm not sure that they will refund or exchange in this condition. Although, they should since I doubt Samsung wants the liability of having these devices out there. Any thoughts on the matter?
Any insight and guidance is greatly appreciated!

https://forum.xda-developers.com/search/forum/3676?query=bricked
basically, you need to download samsung kies3 and let it return to stock firmware.
make sure you have a working usb cable as I had given up on un bricking my note 4 but it worked with a new cable.
