So I've been installing custom roms for as long as I can remember but I've come to a part where I am kind of stuck.
I upgraded my phone to the S9 Port rom Alexis and on the latest V5.6.1 I ran into an error that can't seem to be fixed.
/mount/data error in TWRP... I've done all the wipe and repair and stuff in TWRP and yeah it works great no issue and then when I reboot the phone wala… Same issue... No data mount error again and it's seems to be unable to cure so I can't even install any files at all through TWRP as all my memory shows as 0.
I'm wanting to flash back to stock on a GALAXY S8! but obviously going to an S9 port changed my model number to G960F.
How do I go by this? I don't wanna use odin to flash back to a G950 and run into the risk of it completely bricking my phone... Can I actually install an official stock rom of G960 on my device and make it a Stock S9 rom on an S8 or will installing my old model number file make it go back to the stock S8 rom?
Unless someone knows a fix to my issue with TWRP /mount/data error then i'd be greatly appreciated but right now i'm just thinking back to stock and then re-root.
Thanks in advance!

I am using Aryanof s7 edge port in my note 3. I need to restore everything back to official. So I think I need to go back to 5.0.
Do I just download the official from and install in obin? How can I restore bootloader too? Thanks.
Use Odin to flash the latest stock ROM for your phone. The stock ROM will include the bootloader, modem, system.
Thanks. Any special instructions I need to be aware?
I tried to downgrade for my previous s2 but it becomes bricked several years ago. I then notice some big version cannot downgrade. That's why I create a thread.
Let me try
I recommend flashing the latest stock ROM for your phone. This will ensure that the bootloader and modem are not being downgraded.
unfortunately, the phone is bricked.
there is a need for me to use the latest stock rom which is 5.0. May I know what I can do?
My retailer gives me some discount for my new phone but I need to restore to the stock rom
If the phone is bricked you can do nothing .Bricked is dead phone .
How did the phone brick?
It keeps rebooting. I then tried to flash another 5.0 stock ROM and due to other things happen, I just leave it there. Amazingly, when I come back, I see the setup screen.
Now i successfully downgrade from 6 to 5. Thanks
I'm trying to flash roms on my N9005 but I'm not able to succeed.
I tried first flashing the Fougat rom, I got stuck at Galaxy note 3 bootloop
I tried the Lineage 15 rom. It required TWRP v3.2.1, tried flashing it, but it didn't load
Tried flashing MagMa NXTeam's rom, same with fougat.
Im sure %100 I followed devs steps to flash but nothing is working for me!
Help devs, please!!
Did you confirm the model # in download mode?
Did you try flashing other ROMs that work with an older version of TWRP?
The phone is running the latest bootloader and modem?
1 Its not a N9005 or a fake .
2 User flashing stuff not for a N9005 .
3 Possible damage to a partition .
Judged by previous multiple users posts its likely partition damage .

same for me since i change complete screen LCD+tactil.
Original rom work great but no custom rom. I bought complete screen on china ebay store.
Is screen version is really same that mine ? how to verify ?
I've read through a couple of your posts you've made on several ROMs and even TWRP, it sounds like you are flashing the wrong version for your phone. In several instances you've asked whether to install hlte, in the TWRP thread it seems like you're just letting the phone reboot (which re-installs stock recovery). You might either want to research more into what you are doing before you brick/damage your phone or leave your phone on stock.
I had custom roms installed on my device but decided to go back to stock rom. I was able to restore the stock rom, updated and installed twrp and root on my device. I noticed that after I did this, my headphone jack stopped working and my PC doesn't detect my phone for USB file transfer or MTP configuration anymore (on stock, rooted). I wanted to know if I have the same problem on custom rom so I flashed a custom rom and both issues are resolved. Although I liked the Custom roms I tried (Havoc OS and Arrow OS Pie), I decided to go back to stock again this morning because one particular game that I'm playing (Mobile Legends) isn't working properly on custom roms (screen would sometimes flicker or go into black screen, I didn't experience this on stock). This time I decided to forget about root and relock my bootloader. After updating, I ran into the same problem with my headphone jack and usb file transfer. Does anyone have the same problem? If so, how did you get the headphone jack and usb file transfer to pc working again? Please help. Thanks.
I am facing the same problem ! anyhow installed lesser and switching between speakers and headphones ! Usb still isn't working !

The only way I could use usb file transfer is when I boot into a custom recovery. I went back custom rom for now, until I find a permanent solution for both. I tried searching for answers at the Zentak forums but couldn't any help there.
Have you tried flashing the raw firmware first than update? It's here somewhere on unofficial unlock/re-lock post, I went back to stock ROM after re-lock without any issues. I did have an issue flashing using AFT after re-lock, but flashing corresponding recovery.img than flash firmware using recovery solved that.

Hi! Thank you! My problem is now fixed, both headphone jack and USB file transfer, although I'm not really sure if it will work for others. What I did was I flashed (while device is unlocked) the Nougat raw firmware (WW_ZE552KL_14.2020.1712.85_M3.10.47.15), tested it and both were functioning. I decided to update to Oreo using the system update feature and it is still now working after I installed all the Oreo updates. I'm not planning to re-lock anytime soon as I installed root and found it beneficial.
I did follow the unofficial unlock/ re-lock prior to doing the previous steps, although I first flashed the factory raw rom (CSC_ZE552KL_13_13_1_36_M2_6_7_P7_userdebug.zip), unlocked and the flashed the Oreo raw firmware (WW_ZE552KL_15.0410.1806.68_M3.10.47.19) . Maybe skipping to flash the Nougat Raw firmware caused the problem? I'm not really sure, sorry I'm relatively new to all these.
Glad to know it's all ok on your part

Yup you should flash Oreo RAW as custom ROMs (Android 8 and above) needs latest modem.
Hi Guys, hopefully someone will be kind enough to help me out here!
So I flashed my S7 Edge with Superman Rom a week or so ago and loved the Rom itself, however all I have got since is no signal, no imei, and won't read my sim. I've tried everything I can 're flashing Rom, trying to replace efs file (no backup as it got deleted ☹) and tbh I really haven't a clue what else to try.
I did try to refresh a stock nougat Rom through Odin but this now fails due to boot.img ?
So bloody lost.
If anyone has any ideas what to try I would be really greatful.
Cheers
Matt

Thank you mate! ...seems that the firmware I was flashing was not the newest version so couldn't update the boot to flash. Downloaded most recent Oreo and it flashed through dirty. Had to then flash TWRP and new root before installing would complete past the dreaded 'No Command' with yellow triangle screen! (Probably my fault for dirty flash - but just incase yours doesn't fully wipe if you get same problem as me). Rebooted and Oreo installed no probs and both my signal and IMEI have returned!
Custom ROM flashed and all still working no probs.
Much appreciated for the help!

Good
Hello,
I have a problem converting samsung note 4 n910p to n910f. At the beginning I dowloaded TWRP and flash it by Odin. I made a backup of everything then downloaded the rom for samsung galaxy n910f Pixel Experience. When installing rom I get a message "ERROR 7". It occurs when installing each custom os example: ViperOS, HAVOCOS rom. All the time there is the same problem. On the xda forum I found a user manual how to flash the baseband firmware. I flashed OK1 - nothing has changed then PE2 - the same, "error 7" is still there. I also tried the Trex888 user manual to install T-mobile OS + ramkernel + datafix and the phone stops while loading - bootloop and the teelphone temperature is rising that I cant touch it when I leave it on the bootloop.
Do you have any verified way to install custom rom to n910p? It's hard to find a clear instruction on what to change to flash a custom rom on n910p
I restore backup and have a bootloop on the sprint logo
I ll try to instal Dr Keaton rom with H-vitaminkernel, maybe this ll help...
see
https://forum.xda-developers.com/showpost.php?p=68967827&postcount=2
and subsequent posts in that thread
I will check the method described in this post again, but I did it before :crying:. All new roms with android 9 like for example havocOS have written that they also work with trtlespr. This is written in the information when installing the rom in twrp. So why does error 7 pop up for?
I did the first method by installing the PE1 baseband from this topic:
https://forum.xda-developers.com/note-4-sprint/development/basebandsbootloaders-ok1-pc1-pb5-t3358357
Then, according to the instructions, I installed the system, krnel and datafix.
"Try this rom this will work flash rom and dartafix and kernel all together
Download rom
https://www.androidfilehost.com/?fid=385035244224381907
Download data fix
https://mega.nz/#!qcdnySyB!55DemVnZN...a0u4_V60fn5mKo
Download kernel
https://www.androidfilehost.com/?w=files&flid=117985 "
The system doesn't start, it stays on SAMSUNG screen and gets bootloop. The phone heats up very strongly within a few minutes, it is possible that even the processor temperature is higher than 80 * C.
By installing firmware and baseband PE1 from the above link in Odin shows that everything is ok ( success). But can it be that, despite everything, the baseband did not get in, therefore it does not accept this rom or any other?
The same example, when after flashing TWRP by Odin, if we do not disconnect the battery, TWRP will not install. Is this possible with baseband and frimware for PE1?
Ok, I tried everything that was in the post you linked. I flash my phone to PE1 firmware, then install dedicated rom, datafix, kernel from links and phone stuck on samsung loading logo. This situation i s always when i try any rom. When I do a restore backup phone stuck on Sprint logo...
Can anyone help with this?
Has anyone ever installed a customrom with android 9 on n910p?
I have sm-n910f as a backup and I can do anything on it.
Are these n910ps somehow handicapped?
n910p that I ave is in very good visual condition, without scratches. If I can't do anything with flashing new rom on n910p phone, can I buy a motherboard from n910f or n910c and install it inside instead of n910p board?

Thanks, for the reply. maybe I ll try to once again install the customrom before I order the board form China :cyclops:
Can someone explain me how to install example HavocOS ( android 9 ) on n910p? This is possible because when I install it in TWRP there is information about compatible version of phones and there is "trtlespr". So it must be possible to install HavocOS on n910p
Why I need to change the rom in this phone? I live i Europe so Sprint stock rom dont want to connect with my Red Bull Mobile or T-mobile operators...
Ok, I install Dtux Rom on Standard PK1 Sprint rom. Working, but I hv problem with T-mobile network. Everything is working on the GSM module but without internet. When I go to settings and then network -> change to CDMA or LTE I hv information "Searching for service" and no signal. So how to activate mobile data - internet connection on this rom? I know thath LTE is not working in EU with Sprint N4 but even CDMA is not working
