Flash a stock ROM via Odin and then proceed installing your ROM by flashing recovery...

Hello,
Try to install an official ROM, for your phone, with Odin then root again and install Custom recovery. I advice you to download latest build of recovery.

will it be okay to select reboot to download mode when it is giving a message that no OS installed, are u sure to continue
PS. i am having TWRP v2.8.7.0 which is latest i guess
You have tried to install a new rom with Odin?

i am still downloading firmware from sammobile
its very very slow, can someone tell a workaround?
Yes, downloading from sammobile.com is very slow unless you are a paid member.
If you want to run a custom ROM, there are ROMs that can work on your phone and would be faster to download. There are even ROMs that are based on Samsung's TouchWiz.
thanks guys for ur support
i was able to revive my note 3 again
but i did the whole rooting process again by auto-cf-root and then twrp latest through odin and i am still struck on the same screen like the last time in twrp recovery
it is still not able to mount system
can anyone has a solution?

Flash supersu via TWRP instead of using cf-root.

but to gain root access, i assume auto cf root is the first step
correct me if i am wrong
Flashing supersu from TWRP will get you root access.
i am writing the messages twrp shows if they matter
updating partition details
E: unable to mount /cache
..done
E: resources (font)- (fixed) failed to load
E: unable to mount /cache
kernel doesnot have support for reading SELinux contexts
E: unable to mount /cache
E: unable to mount /cache
MTP enabled
E: unable to mount /cache
E: unable to wipe dalvik
updating partition details
E: unable to mount /cache
..done
E: unable to mount /cache comes multiple times later too
Steps: install again the rom, next step it is to install custom recovery with odin(The Rom and recovery must be in .tar format) and the last step, search for supersu in format zip and download in to sd card. Boot you phone in to recovery and install supersu. Now you will have an rooted phone.

Maybe cf-auto-root is changing something in the phone to cause the error in twrp?
well i was third time lucky
repeated the same process 2 times:
rooted with cf-autoroot with odin, flashed twrp with odin, still freezes
3rd time:
flashed official rom
did a factory reset by inbuilt recovery
installed cf-autoroot, flashed twrp by odin
this time i was able to install aurora rom despite the error message in mounting cache
so running aurora rom now...
will try to flash supersu through recovery as recommended by @bogdan109
but will take a good night sleep first

Check if your phone it is rooted or not (install an program from play store: root checker). I don't think it is necessary to install super from recovery, now when you used cf-autoroot, but maybe i'm wrong.
Flashing supersu from recovery means not having to use any other root tool.
thank u guys for ur replies
i dont know the reason of the problem but it seems almost sorted out now
what i did was i flashed older version of twrp twrp-2.8.6.0 and used suemax kernel
since then it seems okay though on running recovery it still tells one problem:
E: resources (font)- (fixed) failed to load
but everything else has been resolved for now
thank u again

[Q&A][G900h][Recovery problem][can'accsess the partition for wiping in recovery]

Hi all.
i have a Galaxy S5 G900h.
i upgraded it to stock lollipop with OTA
i downloaded a port s6 rom to install it but when i open the recovery[TWRP Rcovery] and select wipe option and enter it , there is nothing to select that what wipe it!!?
i tried other recovery like cmw and philz but problem is not recovery.
i think its for selinux but if my guess is turu, i dont know how solve it.
you tell me
any way . . .
i shared this post to help me if you know.
tnx

please helpe i accidentially wipe all os system and data of samsung s3 neo i9300i

my device is samsung s3 neo i9300i.recently i install twrp 2.7.1.0 and accidently delete all partitions and system and data.so now there are no os system.and i cant boot my phone.phone stucks on samsung logo.but i can boot into twrp recovery mod.then i decide to flash stock rom throgh twrp recovery but it fails and also try cm 12.1 official and unofficial it also fails.its showing no md5 file found.patching system image unconditionlly and updating partitions.so what can i do.i dont have pc.so give me solution which can i solve with twrp 2.7.1.0 .and one que. can i install noble rom 2.1 on this mobile in this situation?please help me......
I think you still need to find any PC with samsung drivers installed and Odin. Boot into download mode (vol down + power) and flash service firmware to recover partitions. Maybe exist any other solutions, but this, IMHO, is what you need to do.
After installing cm12.1, doesn't it boot?
Don't worry about the md5 file warning or patching system unconditionally. If you got no errors (other than what i mentioned here), it should boot fine.
in twrp there is an option of terminal command.but i dont know how to use it.when i click to open this terminal conmand then open systems folders and files and bottom line there is a option of select current folder.so how can i use it to flash rom with this.anyone have idea then please help me
I several times wiped everything at once through TWRP, then just restarted into recovery, copied .zip files for the ROM and gapps from a computer and flashed them, so can't really see where is the problem in your case. Doesn't the PC find your phone as a storage drive after wipe and restart?
yesterday i successfully install nobel rom 2.1 in my device.but now problem is i cant boot my phone.its showing samsung logo and then automatically going in download mod.before this installation i several time wipe every partitition and succedsfully install noble rom 2.1 but cant boot my phone.problem always there.please please help me
Maybe the problem is with the ROM and it's incompability with your phone. What if through Odin you flash a stock ROM from a computer in download mode and then try another custom ROM?
But of course first try to enter recovery and directly flash (another) working ROM, because going through stock with Odin takes much more time and nerves. Also, with Odin you have to be extremely careful to use the exact stock ROM for your device, so this is kind of a last-case scenario.
Plz check the rom u r downloaded is not corrupted
Or download again by any other phone and save it to external sd card then plug it on ur s3 and flash it
plz can any provide me twrp nandroid backup of system and boot partition of s3 neo i9300i plz plz plz
because in my area downloading speed is too slow.so i cant download stock firmware.its getting corrupted.i try to download it 4 to 5 times but its getting corrupted.so plz provide me backup file
U can't install stock firmware with twrp.
It can be flash using odin for pc only
ya.i know that.u mistaken me.i don't want stock rom.i want backup file of rom.just like that when we do full system backup with twrp recovery before installing new custom rom.are u understand my friend.please help me yaar.my phone is off from 2 months so please please help me .i want backup file of system and boot partition using twrp recovery.

If you deleted ALL partitions, you have to flash Stock. If not, then just install something.

Yes of course you can. Flash whichever version you want. Just make sure it is only for your device s3 neo not any other Samsung phone. If you have solved the problem, then reply here and all moderator to close this thread.

Please Help :(. Bootloop after re-flashing stock rom 6.0.1

Hello,
Please help me out guys
I tried for the 1st time to flash custom recovery TWRP - it worked.
Then, i immediately entered to TWRP and i tried to root my phone installing the supersu.zip. When i rebooted my phone - bootloop
In the end, I reflashed stock rom via ODIN but my phone still gets bootloop at SAMSUNG LOGO(NEVER HAPPENED BEFORE)
PS:If i try to enter stock recovery - first it appears "installing system update", then "no command" and then it enters the stock recovery, but nothing can solve the bootloop problem
please help
1.Why bootloop after rooting with the supersu.zip?Should i use the cfautoroot metod?
2.Why bootloop after reflashing stock rom?Never happened before!!!
Thanks!
What Phone have u got mate?

J500F....
I think i managed to solve this...I was flashing the 1st update package .tar which was released for the J5 last summer
Flashing that - not working NOW, ALTHOUGH it worked a few months ago
Flashing .tar from SAMFIRMWARE - working!
But what about the root problem? Which way is the proper way to root your J500F 6.0.1 without bootloops&stuff

Nothing works: supersu.zip, cf auto root.zip....
i only get bootloops
After flashing using TWRP you should always clear dalvik cache,
The first boot always take some time, 2-5 min,
Before flashing anything try to do a nandroid backup,
The supersu.zip method worked for me,
There is a detailed thread on xda j5 forum on how to upgrade/downgrade and root your device,
After using Odin to flash a ROM enter recovery and wipe data then wipe cache
Sent from my SM-J500H using XDA Labs
Update:
1. It seems it ONLY works to flash 6.0.1 AFTER flashing 5.1.1.(so i have to always repeat this double procedure)
Reflashing 6.0.1 over 6.0.1 - NOT WORKING
2. About root problem - damn, i still can't make it work. I will try your advices and let you know what happened,
Thanks!

I've seen your PM.
I don't really have any idea. But I have a suggestion, although I don't know if it will solve your problem. Backup your stuff from internal memory before. Try to wipe everything including internal memory (internalsd in TWRP recovery), then turn off your phone and re-flash stock rom.
Hello, @Lawr3nce I followed this tutorial by @rjrulz007 http://forum.xda-developers.com/galaxy-j5/how-to/tutorial-upgrade-j5-2015-to-6-0-t3443904 to root my j500h, I downloaded the supersu.zip from this link http://forum.xda-developers.com/apps/supersu/stable-2016-09-01supersu-v2-78-release-t3452703
Don't forget to backup your data before upgrading (you can use smart switch), after flashing using Odin go to recovery (stock recovery), wipe data/factory reset and wipe cache partition, this should solve the boot loop problem.
Before flashing the supersu zip file do a nandroid backup using TWRP (boot to TRRP, choose backup, select sdcard as save location then swipe to start backup. In case the flash of zip file failed choose restore and select the backup you did before, better than reflashing the whole ROM using Odin )
Sent from my SM-J500H using XDA Labs
Ok, thank you all for the help. Conclusions:
1. For some reason, it NEVER works to flash directly the 6.0.1...I always have to flash the 5.1.1 first, then the 6.0.1.
2. I will try that root procedure from the link .
I am very willing to root it because i want to remove many useless preinstalled bloatwares from my phone
(due to very low free space i can't even update my apps)
UPDATE: That procedure with that .zip WORKS! THANKS

TWRP can't mount /data even after clicking Format Data

Hi to all, I've a galaxy S7 Edge (G935F) and installed last stock Oreo rom. I've followed the tutorial on XDA to install stock firmware with odin, install TWRP and root with magisk, disabling encryption flashing no encryption and formatting data. So after format the data I returned to TWRP and it can mount /data so I decided to inzialize my device. After that I went back to TWRP but it can't mount data. The only think I can relate is that while waiting for my app to be automatically downloaded by Google Play, the device first did a soft reboot and the when the Samsung logo was on did a full reboot. How can I resolve this please?
