[SOLVED] SM-N9200 Chinese help needed

Hi,
First post on here. I have bought the SM-N9200 in China after my Z3 screen broke for the second time. I live here (china) at the moment but did not realise that you would be unable to install google play services and therefore google play on the phone. I have a fair few apps purchased on GP and would like them on my phone.
I have read that I would need to have root access prior to being able to install GP but I am running into problems. I have never rooted before even though I was aware of the process etc but have so far been unsuccessful using kingoroot and I cannot seem to find a root method for the Chinese n9200. I saw today that the spaceX kernel supports N9200 so I thought that I would flash twrp with odin and then consider flashing spaceX. However when I try and flash TWRP it fails and the phone displays a message in Chinese that I cannot read as my Chinese is not that great still.
I am not in a hurry to install a custom rom at the moment and mainly just want to be able to get my apps. Can anyone suggest a method? is it possible to install HK Rom onto Chinese n9200 for example?
Many thanks

To flash in Odin you need to enable OEM unlock in Developer Settings.
I tried installing Chinese on HK and it failed (Cache.img)

OEM unlock and USB debugging are on. Odin was run as Admin.
If you try flashing the wrong TWRP (i.e not for your phone) will it fail or will it still flash. I was trying to TWRP for the DUOS version which i am assuming is my phone as DUOS is the dual sim variant?
I will get a chinese friend to tell me what the message is and take a photo of what happens.
Essentially i boot into DL mode and then attempt to flash when the bar fills up the odin still says recovery but the screen on the phone gives me warning (triangle with exclamation) and some information including a the web address for samsung.com/cn

I can help with that Chinese message. There are some problems for you to use GP in China. First, you can use Odin to install HK (TGY) Rom( remember to backup before u do so). After you install HK Rom, you need to connect to a VPN and then go to Google settings.
Hope these info would help you.

Possible solution found in another thread. it seems that the bootloader is locked on some devices and therefore you cannot flash anything.

One question. What would be the difference between the HK and Chinese versions of N9200 other than some restrictions. Is it safe to use guides like the one linked for a chinese version?

TGY is the name for HK ROM. You can find it on samsung-updates. Both Mainland and HK variant share the same specs, which is N9200.

SUCCESS!
So after much stress I have a rooted, TWRP'd, Romd N9200 Chinese version. I say stressed as I had some problems when i flashed TWRP in that it would not let me boot back into the stock rom. this leads me to one unanswered question. When flashing TWRP with ODIN is it a requirement to flash a new rom?? I say this as I had the following problem. When I first flashed twrp the phone booted into stock so I rebooted into recovery only to find stock recovery and no twrp. I checked that the KNOX counter had been tripped (it had) but I was confused. I read on twrp website that on some devices if you let phone reboot into stock after twrp flash rom it overwrites custom recovery. I eventually flashed twrp and quickly pressed key combination for recovery and I had twrp but then I could not boot into stock rom (bootloop).
After spending the afternoon in a state of panic I reflashed the stock rom from Sammobile and was back in business. crisis over and a bit of confidence gained.
I am now using SpaceX kernel following this thread:
http://forum.xda-developers.com/note5/development/kernel-spacex-pure-edition-stock-t3236317
so far no problems so thanks to @Manh_IT
Here is my step by step if anyone finds themselves in same position:
1) unlock OEM and USB Debugging and backup everything using SmartSwitch (this replaced Kies I believe)
2)download CROM apk from Samsung appstore to unlock bootloader
3)Download SpaceX, SuperSU.apk, Gapps and twrp and place all except twrp onto phone memory
4)Flash TWRP with ODIN and reboot into recovery using method described above if need be.
5)factory reset in twrp
6)flash SpaceX and Gapps
7)reboot system and install SuperSU
I hope this helps someone.:good:

Anyone rooted in n9200 with latest OKA firmware?

actually you don't need to root your device...
just make sure OEM unlocked and find a HK version stock ROM and install it with Odin

well if you use N9200(CN)...you can follow the steps to get gapps
Once you use Crom.apk, you lose your warranty , so DON'T use CROM to unlock the phone
Make sure OEM unlocked
Reset to factory in case of some issues
Turn off the phone
Take the sim out of the phone
Get into download mode
Plug to PC and use ODIN to flash the HK stock ROM.
gapps will be install , no root, and you wont lose you warranty , but the battery saving is not as good as CN version.

I have gapps on my note 5 n9200

Hi great to heard that you have managed to resolved this issue. I have the same problem ( I bought my Note 5 in Beijing recently), so please can you explain what I need to do? I can do point 1 & 2 but stuck on point 3 and the rest. Where do I get all these files from?

* G925VVRS4DQD1 * Full Odin Nougat 7.0 Firmware *

Hello!
Here is the full G925VVRS4DQD1 Odin manual update to 7.0 Nougat for everyone to enjoy. You can flash from any current version you have now it doesn't matter whether you are on 5.1.1 or 6.0.1.
https://www.androidfilehost.com/?fid=529152257862722630
If for whatever reason you want to downgrade or don't like 7.0, you can safely downgrade to any of the below versions without any issues. After you flash a lower android version using Odin, phone might get stuck on Verizon logo. If that happens, all you need to do is boot into recovery and do a factory wipe/reset and phone will boot right up after that.
G925VVRS4CQA3 (6.0.1) - https://www.androidfilehost.com/?fid=529152257862700500
G925VVRS4CPL3 (6.0.1) - https://www.androidfilehost.com/?fid=673368273298921946
G925VVRU4CPK2 (6.0.1) - https://www.androidfilehost.com/?fid=385035244224407601
G925VVRU4CPD2 (6.0.1) - https://www.androidfilehost.com/?fid=24566454284190657
G925VVRU4BOK7 (5.1.1) - https://www.androidfilehost.com/?fid=24269982087018504
G925VVRU4BOG9 (5.1.1) - https://www.androidfilehost.com/?fid=24052804347845467

Thanks a lot! I downloaded one from sammobile but there was one only one file, modified date 4/07...
I notice the files within the zip from your link mention REV02 and are dated 4/26.
G925V_G925VVRS4DQD1_VZW_USA_v7.0_IMEIAUTHORITY.COM.zip
2.54 GB (2,732,088,886 bytes)
MD5: 145a137d2c639b30ef5addac9094f331
I have attached the results from HashMyFiles for the 4 within the archive (Filename, MD5, SHA1, CRC32, SHA-256, SHA-512, SHA-384, Modified Time, File Size).

@toutanje Out of curiosity, how did you determine which builds you can safely downgrade to from 7.0? Is it something you personally tested or did someone recently go through the hard work and post their results somewhere? BTW, you can now add G925VVRS4CQA3 (6.0.1) - https://www.androidfilehost.com/?fid=529152257862700500 as two people have confirmed downgrade success here: https://forum.xda-developers.com/verizon-galaxy-s6-edge/help/downgrading-nougat-t3601096 . One used firmware from sammobile and the other directly from the link above. This is the very last build available for Marshmallow.

Hi there. I installed the new update on my s6 edge 7.0 via verizon software updating tool.am noticing the sound quality of mt s6 edge has been changed.before the sound quality was thick and now its not that thick anymore.i want to bring back the thick quality sound on my s6 edge.there is setting called sound quality and effects but i cant manage to get back that sound quality i had with 6.0. Is there anyone who able to notice this change in the sound?

With a very a simple observation, no testing or anything needed
G925VVRS4DQD1 <-- you see the 4 towards the end of firmware build? That is the revision bit number. This means you can flash ANY firmware for that model with a 4 or higher. Take this 5.1.1 firmware for example ---> G925VVRU3BOG5. Even though this firmware is also 5.1.1 like the ones from above, this particular one will NOT work because it is on an older firmware revision bit (3).
The same is true and goes for ALL Samsung phone/tablet models and firmwares.

That is very good to know. Yeah I noticed it about the firmware naming convention but I had no idea what the value means (or the character before revision bit, U has become S). My phone out of the box was on G925VVRU3BOG5, so I guess I could go all the way back to G925VVRU4BOG7 if "needed" lol.
One of my fears about Nougat is about all the work they did to automate and place updates into the background. This could allow disabling of downgrades, or anything else at the discretion of Samsung and/or the carrier. I think this has already been done in Marshmallow, just on a smaller scale for security fixes. Anyway, it seems to me like an attack vector waiting to happen: less control over my phone combined with an easy way to break things. Imagine all the troubleshooting fun we will have.

So I upgraded to nougat. I'm having battery issues and just want to go back to marshmallow. but I'm having problems. The nougat rom installs just fine with odin. But when I try with any of the 6.0.1 roms it was failing. Then I noticed that re-partition was chcekd. So I unchecked it and now it goes through the process just fine. But now the complains with dm-verity verification failed. I can install nougat on it no problem. It's just the downgrade that's not working... any clues?

I actually managed to get the N925V to downgrade all the way back to the firmware version G925VVRU3BOG5.. May have cost some money for some very specific files but my phone's back on G925VVRU3BOG5 and it's really only a test phone for someone I do work for! I have it rooted with SuperSU and not kingroot and I created a script to keep the phone set to "permissive" so it's able to do full reboots and not just hot reboots using xposed... Unfortunately it seemed like no one cared about it when I posted it in the other thread so it's probably not worth it to a lot of people but I think it is with the amount of fine tuning I did to get it to where it is today!!

Mike! Can you explain how you did it? I'm stuck on nougat. Every time I try to downgrade, I get the dm verity error. I've tried all the 6.0.1 version and the 5.0.1. No luck . I'm back on nougat. Can you please let us know your process... Thanks!
Did you have to select anything special in the options? I just left it at default which is Auto reboot & F. Reset Time.

I mean I could but I had to shell out some money for this firmware and I don't even know if you can flash it with odin because I don't use odin I bought a box to do my flashing since I work on so many phone's and odin just doesn't cut it.

No Worries. Finally figured it out. Good luck to you

I was able to use this to flash my Samsung Galaxy S6 Edge from 5.1.1 to 7.0.
Not that I want to upgrade again, but is there a 7.1.2 available? Is there a routine schedule for that sort of thing or was the 7.0 Nougat think kind of a special case?
Thanks!

I haven't been keeping up, but now curious. Verizon shows DQH1 as current (a 7.0 build), while sammobile and androidfilehost show four builds available (all 7.0).

Ok, so I updated my G925V with nougat, now I'm just wondering if anyone has come out with a way to root this build? That's what I'm waiting for. Plz fill me in when that happens. Thanks.

I use the Z3x box and Octoplus box I have 2 of them for different phone makers but I have so many different wire connectors that I lost count because what works on Samsung doesn't work on LG, HTC etc etc.. You can find them pretty cheap but I'd avoid buying from eBay because of to many scams selling broken or bad boxes that can't be activated.

You unfortunately cannot downgrade the bootloader once you updated to 6.0.1 you lost the ability to go back and there's so far, no way possible to do it.

Note 8 soft bricked

Salutations everybody. I haven't had a phone from sammy in a while. Finally invested in a SM-N950F note 8. It's oreo. Tried to root earlier today using the pinned guide in the Guides forum. After going through the process, and flashing twrp. Then formatting data. And rebooting it to twrp (which I did a couple of times) (May been where I messed up,but it doesn't seem likely to me) I flashed the oreo n950f oem issue zip and rooted with magisk. Upon rebooting & enabling dev options. The oem toggle was missing. The guide didn't say what to do in the event that it was missing. Just that it was safe to reboot if it was there, and enabled.
Me being rushed for time rebooted anyway, and now when I try to boot up I get only official released binaries may be flashed, and the phone shuts off.
I'm aware I can restore to stock via odin. But I have a couple of questions.
A. Can I use the same odin version I used for the root process to return to stock, or do I need a different one?
And
B. There are loads of options for country and carrier on sammobiles site. I bought the phone used and have no idea of its country of origin. There is a version that says unknown for country and (bat) for carrier. Is that one safe to use, and is there any difference between the firmwares other than carrier setting being preinstalled (would be my guess of the only difference.)
Thanks in advance for any help you can provide.

This msg Only official released binaries are allowed to be flashed cause of the new security patch lock which called RMM or KG and since u were rooted before then u got this error that's cause you flashed a new BL to your device or you were connected to internet before editing kernel to prevent samsung to add the new lock to your device anyway a normal flash through odin will solve your problem and your device will be ready to use it again without any problems but also without any custom files like TWRP and Magsic which means u will not be able to root your device before editing kernel to remove the new security patch lock

Okay I was thinking I might of missed something. The patch for oem issue I thought covered that.
Is the unknown (bat) firmware the one I need to flash to stock?

Using odin 13.1.3 is recommended.
As you have the N950F, it is part of the multi OXM CSC, so you can flash the filmware for you country and carrier if desired (N950F)
If you want to root, I suggest just flashing a custom rom or kernel, as they have been patched for the RMM KG state issue.

[samsung note 8][revert to stock firmware from custom]

Alirghty so i bought a used samsung note 8 duos. it says it on the back, in the software, in smart switch, heck even the AP and CSC files are infact for a SM-N950F
Here is where the problem is as far as I've figured out, I'll explain what the firmware files are on the device taken from dialing *#12580*369#:
BL:N950NKSU5DSK1
AP:N950FXXS7DSH1
CP:N950NKOU5DSH1
CSC:N950FOXM7DSG1
The phone runs fine honestly but its bugs me that there two different binaries mixed in my phone from what i can tell the BL and CP are from a Korean level 5 Binary (also can someone tell me why security levels matter now?) and the AP and CSC are from F model level 7 Binary
I cant flash anything stock cause its the only thing ive tried and it just wont let me. I am downloading a level 5 binary in *hopes* that it doesnt see an issue with the security levels between firmwares as i always get the fricken PIT error or secure download error orrrr the magic string invaild
All i need is a way to get my dualsims back up and running ive got two imeis on this phone which ive checked online and theyre working also id love it if i could just get all 4 files to be from the same firmware zip
FYI the only thing ive been able to flash is TWRP after which i got to installing no-verity and magisk, Ive been using twrp backups as a failsafe to revert back to the 'original' state my phone was in and thats the only thing working for me so far and i may or may not be a noob in flashing samsung devices

The reason for that is because the phone has obviously been repaired using different hardware from different devices. It's never going to be able to flash normal firmware being that there's different hardware in it. If you want to upgrade that you'll need to use the different versions of firmware for each different hardware.. I'd just send it back if I bought it from somewhere like that.

Revert to Stock
I owns one Galaxy Note 8 SN950-F Indian version,
I have installed one custom ROM for my mobile last month and now i need to revert back to stock.
How can i do it ? Once i installed stock OS using Odin but Knox looks crashed and apps like secure folder not working !
Can i get it done through service center ? When i contacted them they said its impossible as you have rooted once.

Once Knox is tripped it takes a motherboard replacement to revert it.
If SF (Secure Folder) is that important to you, stay on a custom rom that has patched SF patched already.
Literally all TWRP/Rom threads warn you of this, always read the whole OP of any thread in the future.

Yeah. Thats what im doing now. Running on doctor ketans rom.
but im little worried now. Because haven't used any custom roms and worried about security issues.
Can we still go back to stock os ? With genuine updates?

Just follow the steps in the thread below. At the bottom of post #2 you can download "samfirm" for you Pc, it will let you download the latest filmware at a decent speed. (once back on stock you should disable OEM lock so your bank app, Netflix etc will work)

Like I said to you above, once Knox is tripped SF won't work, if SF is that important to you stay on a custom rom that has patched SF. If you're worried about security updates use DeluxeRom which has last months security patch.

Alirghty so i bought a used samsung note 8 duos. it says it on the back, in the software, in smart switch, heck even the AP and CSC files are infact for a SM-N950F
Here is where the problem is as far as I've figured out, I'll explain what the firmware files are on the device taken from dialing *#12580*369#:
BL:N950NKSU5DSK1
AP:N950FXXS7DSH1
CP:N950NKOU5DSH1
CSC:N950FOXM7DSG1
The phone runs fine honestly but its bugs me that there two different binaries mixed in my phone from what i can tell the BL and CP are from a Korean level 5 Binary (also can someone tell me why security levels matter now?) and the AP and CSC are from F model level 7 Binary
I cant flash anything stock cause its the only thing ive tried and it just wont let me. I am downloading a level 5 binary in *hopes* that it doesnt see an issue with the security levels between firmwares as i always get the fricken PIT error or secure download error orrrr the magic string invaild
All i need is a way to get my dualsims back up and running ive got two imeis on this phone which ive checked online and theyre working also id love it if i could just get all 4 files to be from the same firmware zip
FYI the only thing ive been able to flash is TWRP after which i got to installing no-verity and magisk, Ive been using twrp backups as a failsafe to revert back to the 'original' state my phone was in and thats the only thing working for me so far and i may or may not be a noob in flashing samsung devices

I am having this same problem.....my phone got bricked so i was looking for my stock rom but the only stock rom that works with my Samsung note 8 is the korean version which supports one 1 sim but my device is dual sim

Good source for firmwares?

I'm looking for a good source of firmwares, i know the famous sites but some firmwares doesn't seem to be listed. I know in the time os Samsung KIES there were tools which communicated directly with samsung.
For example these firmware builds for the SM-G975Ux aren't listed on most firmware sites but have the December secutiry update with binary/bootloader version 8: G975USQS8IVL1 and G975USQS8IVL2

All the big sites have ROMs for that phone (same one I have). There is no "Ux" model... it's *U or *U1, with the latter being unlocked. IF you search for U1 ROMs you have many selections, but most get the XAA version which will usually change carriers automatically based on the SIM card.
The latest BL=8 version I see there is https://www.sammobile.com/samsung/g...M-G975U1/XAA/download/G975U1UEU8IWB6/1741280/ which is the February 2023 security update. I believe this is the last one we are getting (but I could be mistaken as there may be 1 more security patch, I don't remember).

There's U U1 0 W F N .... I'm looking for the oldest firmware with binary version 8, but it seems the sites don't show all firmwares available.... i'm looking for the oldest firmware with U8 bootloader (or any compatible bootloader with binary 8 version), i could have a look at all sites and try my luck... but they don't seem to have all data. but like i said i prefer some original source xml files... i saw some url's to original samsung servers but can't find them anymore.
There is already a firmware available with the march update.... but you have to be lucky to find them... i'm looking for original sources. like update.zip's and such
Found the first one....
https://fota-cloud-dn.ospserver.net/firmware/TMB/SM-G975U/version.xml

I'd recommend around sammobile and samfw. These are the two sources I use the most

hey!
after I wanted to update my g973f from "G973FXXUGHVK1" to "G973FXXSGHWC2" (I tried odin 3.13 and odin 3.14) and an error occurred, I can't install anything anymore... recovery and download mode work, and I can also flash the original firmware, but the device no longer boots into the system! even custom roms don't want to boot anymore
Can anybody help me further?

Do you mind explaining a bit more? Do you mean like that it boots you into recovery only or?

if i flash a new rom (whether original or custom rom) nothing happens after the reboot... download mode works too, flashing twrp works too! however, the system boot does not work via twrp either... not even a bootloop, the cell phone does not react at all! the task combination for

Right now I don't even care if I get the original firmware or a custom rom running... I hope I didn't brick it (((

My old device was a G930F, its unbreakable make sure you flash the right rom and wipe data and dalvik cache after flashing.... THis ons is locked so it doesn't have fastboot. My G-930F came with fastboot enabled so you can always fastboot a recovery.img. like TWRP
Did you try to download TWRP from twrp.me and "fastboot boot twrp-3.7.0_9-0-herolte.img" ? it should boot to twrp in fastboot mode (hold volume down + home + power).

1. is your KG status is broken?
2. Is your bootloader unlocked?

You know how to flash lineageos through twrp right? and how to use odin?
Maybe flash lineageos to see if everything works.... and then revert to original software. Be sure to wipe cache/dalvik and userdata

Yes, I know there are many other variant firmwares out there, but for a U phone (snapdragon) there is really only U and U1... the rest are incompatible.
There is no "older" firmware with binary 8, because the firmwares are packaged with the proper/compatible binary already. Basically, the "binary" is the bootloader version. On Snapdragon phones, you must have the proper BL/binary to flash, as you already know. You can't interchange the binary/BL with the ROM and security updates because they are not made that way.
The update.zip you're looking for are updates sent by Samsung directly, and they can update the ROM (and Binary) from one stock version to another... but, again, they will update both the binary/BL as well as the ROM, so they can't be broken up to only do one or the other.
It sounds like you're trying to get to an older ROM version (for whatever reason) with an older security patch level as well? Basically, this cannot be done on Snapdragon phones. Once you're on an updated binary/BL, you're stuck there (at least today you are).

I solved the problem! I had unlocked the bootloader, but I also had to deactivate verity via CMD with twrp+adb "adb disable-verity"
ok i've solved the problem now, but does anyone know why i couldn't even start the original stock roms? Actually, the stock ROM should set everything to factory settings...

Thank you for helping so quickly with ideas... I would not have expected such quick help with such an old model, even samsung customer service didn't want to help me yesterday

I've tried different firmwares, its all about snapdragon. You can also flash SM-G975W parts and other snapdragon variants.... there's a lot of variants out there.
I first upgraded and then downgraded to the parts i wanted and am on a rom now with security patch level December 2022, as long as the binary version is the same there's no problem. I've got the latest modem installed and the oldest firmare and bootloader for the latest binary version, i can upgrade or downgrade my bootloader. I already asked someone before if this was possible and if he could confirm because before i was only able to flash CSC and AP i think.
If there's no updates comming anymore why not downgrade and wait for a new leak
I'm also sure we can unlock the bootloader, i'm trying to make an lposed module. I've installed lspatch and lposed and they work fine for some modules. The bootloader unlock has several prerequisites (properties and such) if i can make it look for other properties or something like that we might get an unlock option. Also it looks for an encrypted file on EFS, if someone with an unlocked samsung phone could copy that file we would be a lot further.
It's called /efs/sec_efs/sktdm_mem/encmembership.txt and should be an encrypted file, also if anyone knows how to set ro properties without root (like a stub before the preference controller starts) this would be very usefull.
