[Q] please help a noob, problem note 2!

Hi everyone,
I'm writing you hopping for a clue and some good pointed advices.
My story:
note 2 N7100 rooted started to block. I manage to backup more than 3k sms and around 8 gb of data.
and it works just fine, but I still had a itchy to change the ROM.
I started to read, it was my first time flashing an android, in the past I used to flash with success many time my wm6.5 HTC.
Ok, i'm ready.
i founded some beautiful roms and I was excited to see them on my note.
what did I done?
first I've copy the new rom on sd card.
I follow all the steps for CWM.
the problem was that I followed all the steps till instal. I didn't seen On my sd card the rom that i've copied.
I was not 5 minutes cleaver to pull out the sd card, but I've stopped the phone.
Yes, everything was erased.
The only thing I could get was the starting logo with note 2 ( white letter on black background) nothing more.
I've tried with odin1.85, odin3. every time same result...fail.
I can go in Odin Mode and I can get this message :firmware upgrade encountered an issue.Please select recovery mode in Kies& try again.
I've tried in Kies but no luck
As far as I can understand my phone is empty..
Question is what should I do?
Please don't tell me I can throw it away!!!
PLEASE HELP!
Please if you will respond on this thread make it like for a noob!
Thank you in advance

what Rom u was installing ?
i think u should use Odin 3.07
http://samsung-updates.com/Odin307.zip
find latest stock Rom for ur N2 ( N7100 or N7105 ) here : http://www.sammobile.com/firmwares/1/
download it and unzip it then open odin and put it in PDA and wait a bit it will check MD5 then it will work then put ur note in download mode ( home + vol down + power ) and connect ur note2 ( odin should give u blue color on ID com )
and make sure Kies is totally closed then hit start and wait
like this

thank you for your feedback.
I've downloaded the latest version for N7100 from the site you mentioned.
the truth is I've used Odin 3.04 and have no luck.
I've followed every step you mentioned.
I'll try with Odin 3.07.
I can't go to recovery I don't have this option or I don't know how to access it.
When I press those 3 buttons the phone goes into download mode.
How can I access recovery?
Thank you Yahyoh

to go to recovery use home + vol up + power

I've done that and I get the death message ( i've read about this death message, I want to hope that is just an over reacting saying)
"firmware upgrade encountered an issue.Please select recovery mode in Kies& try again"
in my opinion, if I'm allowed to have one, I think I deleted everything on my phone. even the bootloader and so on.
Is just empty
which are the steps to follow in order to have a working phone?
thanks Yahyoh for your attitude and patience.

Remove battery for 5min
Press Vol down +home+power
It should reboot to download mode
Instead of download mode still you getting msg 'encountered error...' consider that screen as download mode and flash rom with odin.
Version of odin doesn't matter.

Boot your phone to download mode by pressing vol down+home+power buttons together. Then plug in the usb cable, run odin and select the md5 file. Click on start. Be patient it should automatically reboot within a few minutes. If it doesn't try flashing a custom recovery like TWRP through odin and do a full wipe before flasing. Hope it helps!!

What error do you get in odin when flashing stock firmware?Is your phone being detected by odin in the first place?Is the ID:COM port lighting up blue which means successful connection has been established between phone and odin.If ID:COM doesn't light up then you need to change your USB CABLE (if you are not using stock samsung cable ,if you are then use another stock samsung usb cable)Screenshot the error if any you get in ODIN and upload it for us.

Definatly seems like there was an issue with Odin, but you need to get it into download mode to return to stock then try again.

Had the same ****; Please check if your internal storage is available. Mine has the exact same problem and it could be due to faulty hardware (emmc).
To check if the internal storage is mounted check your recovery. it will indicate that it couldn't mount system and a range of other mounting errors. You could use adb to see which volumes are mounted.
(Check my thread http://forum.xda-developers.com/showthread.php?t=2716444 it has detailed info about how to check your volumes)

Your phone is an International model Note 2. The model number GT-N7100 tells you that.
Can you repost your attachments/screenshots please so we can can see what's going on

Thanks for the pictures. What was the process you were going through when the error messages appeared on the screen?

I tried flashing the room such the attached picture.
And the failure messages is
Re-partition faild
Sent from my GT-I9300 using XDA Free mobile app

Hi
That seems like a strange way to flash a ROM. Have you looked at using ODIN? It's the best and most reliable way to flash a ROM.
Have a look at these links
http://www.jayceooi.com/how-to-install-firmware-on-samsung-galaxy-note-2-with-odin-video/
https://www.youtube.com/watch?v=nyNmR_tsD90
Let me know how you go
Thanks

I have already used ODIN V 3.04 and the attched Picture shaws the files which I used. But unlikely each time I try to flash it told me " operation failed "and the failure message is " re-partition faild "
I wish I could explain the issue.
Another way to explanation:
1- I tried to flash from recovery with no luck.
2- I have been downloaded the files which appeared on the last PIC
3- I used Odin 3.04 to make a new flash.
4- go to the Download mode and connect my phone to my PC then clicked on Start button on odin after selecting the pit and PDA ....ext files.
5- it seems working well but after 2 minutes I got the failure message "re-partition failed"
Several tries one with check re-partition box another without. Trying flash with Pit file and remove the other files . Trying flash with PDA file and remove the other files. Each time I get the failure message "re-partition failed".

Mr Hesham
it looks like you have the same problem as I did with my Note 2. Getting stuck with a re-partition error looks very much like it is a failure of the eMMC chip.
First, pull the battery for a couple of minutes.
Reinsert the battery and go to recovery mode (VOL UP, HOME, POWER) and perform a factory wipe/reset.
Then go to download mode (VOL DOWN< HOME< POWER) and connect to PC
Open Odin. Make sure phone is connected to Odin
Download the file http://www.sammobile.com/firmwares/download/26440/N7100XXUENA1_N7100OJVENA1_EGY/
Flash the file. Select it via PDA. Do not extract the file.
DO NOT flash the PIT file and leave re-partiton unckecked.
Send a screenshot off the PC of what happens

when used odin controlled the box "re-partition" was not checked? because it is one of the most important steps to verify when a rom is installed, the option is NOT checked.

Did you try the step i suggested?

dear Grwalker,
attached the result of the first step of your suggestion.
I'm downloading the file you mentioned on the 3rd step and I'll send you the result once finishing the steps.

Dear Grwalker,
as the attached Pic ODIN can't find the file because it's extention is " ZIP " and the PDA Browser told that the file must be " tar, md5 or smd ".
also you asked me to don't EXTRACT the file.
what shall I do?!

look inside the zip file, if there are tar files just extract and open in odin.
odin needs tar files.
look at the bootom of the page with download link - quick instruction what to do with the zip file

Sorry i should have been more clear. Extract the zip you downloaded from Sammobile but don't extract what comes from the zip.
Select the extracted file in PDA
once ODIN says it is ready click start

Hi, thanks for this helpful guide! I have a question/problem, I did all this steps and the flash started but it got stuck at system.img for more than an hour so I canceled by holding Volume DOWN + Power button, now I have a message saying: an error occurred while updating the device software. Use the Emergency recovery function in the smartswitch pc software. I tried that but my device doesn't show up it just tells me to use it there too. I've retried flashing using the same version but still gets stuck at the same place. I am trying to download my original firmware I really hope it'll work.
Edit: I tried with original firmware and still got stuck at over 50% .
Edit2: I tried using a normal USB-C to USB cable and stock firmware worked

Anyone done this on a SM-N975u that has been bootloader unlocked and rooted?

Is the USERDATA file from the firmware really required? I am thinking of flashing the one UI 3.0 USC firmware ( SM-N975U) in SM-N975U1 and got USERDATA in the firmware i downloaded.

Partly bricked... SM-N975F

Hey guys.. Ive been a visitor in XDA forums for quite a while... And i been running root and custom FW with more or less every samsung from S2 and up...
But i just got my self a note10+ (atleast thats what ive been told) and i wanted to root it up and throw a custom FW on it to run in Samsung Dex...
So i succeded updating the FW. I unlocked the bootloader in dev. options. and unlocked it again in download mode by holding the vol. up. key!
But since then i had problems... every time i run a FW in Odin... Then if i dont get a error saying
SW REV. CHECK FAIL(BOOTLOADER) DEVICE: B BINARY 7
pit_flash_binary - Unsupported version
Then i succeds but when its going to erase everything after the reboot from download mode then it starts up and stops right after... And then i can only go recovery mode and download mode... How do i just write the correct firmware and have it start up like normal... just wanna undo it all... Do i need some kind of samsung support software in windows? and how do i know if it is a note10+ ... Even though download mode says SM-N975F... But still i get error when i flash a FW downloaded with Frija for that model...
Hope to get some help

oh btw... it connects as this when im in download mode:
"Checking Connected Devices: SAMSUNG Mobile USB Modem #2 ( COM12 )"
is that normal?

bump?

Hey there,
SW REV. CHECK FAIL(BOOTLOADER) DEVICE: 8 BINARY 7

This, as far as I understand just means that the bootloader on your phone is on a newer version than the one in the firmware you're trying to flash. Usually flashing just stops there.
Then i succeds but when its going to erase everything after the reboot from download mode then it starts up and stops right after...

You COULD try to simply boot into recovery and wipe the device once, the phone would usually do that on its own but sometimes fails. Mind describing what exactly happens?

For that, you either need the original packaging or just trust on what Odin-mode is telling you.
But still i get error when i flash a FW downloaded with Frija for that model...

I kinda don't trust Frija. For me, Bifrost always worked like a charm. Use it to download the firmware for your SM-N975F and give it your correct region code.
For flashing, some people use Heimdall, I think Odin is pretty simple (as far as simplicity in modding goes).
By the way, if all fails, you could try installing LineageOS 19.1, throw in openGAPPS for Googles apps and Magisk/Lygisk for root (if needed).
Good luck and have fun!
Cheers!

I found out i got EXACKLY the same issue as the guy writing on this thread:
Need help with semi-bricked Note 10 Plus (SM-N975F) - Stuck on recovery/download mode

Already tryed still nothing... But what happens after a 100% succes in Odin is:
Then it reboots and after a few secs it says "Erasing device" for like 0.5 sec... And then it only goes black screen... At black screen then i can only go download mode if i press both volume buttons at the same time for 1 sec. Or recovery mode if i press vol up and power. And thats only if i have a USB-C connected ofcourse.
And whats the issue is... when it stops erasing the device... Why does it stops after 0.5 secs? it normally goes like 2-5 secs ... But also ... After it stops and in black screen... If i continue into download mode and open up the bootloader then...

I been around TWRP, Original recovery and Lineage recovery... But as the guy writes on the other thread. Then it shows 0 MB on the data partition, and i have to format it before it shows up again with 223 (or something)GB again...

Hey there,
Could you try switching file systems around? TWRP lets you format your partitions with stuff like ext4, f2fs and some other file systems. On several custom ROMs, the file system sometimes is the difference between a system working or bootlooping.
Good luck and have a nice day.
Cheers!

Already tryed exfat and f2fs and then back to ext4
