Chinese vs Hong Kong

So it seems a user has successfully rooted the Chinese 128GB/6GB SM-G9550.

1) Can we get verification from others?

2) Does anyone know how to differentiate between HK and Chinese (mainland) versions?

3) Anyone know where to buy the Chinese (Not HK) SM-G9550?

4) Have we confirmed that the HK version has locked bootloader, as as a result not rootable?
[MENTION=6371894]jesec[/MENTION] perhaps you could chime in with your experiences? or is this HK vs Chinese difference just a bunch of baloney?

Trying to get a coherent set of answers in one post for all to see. Thanks again for all the help

Crom service FC G9550 6GB/128GB

- Sec. Patch 31 May 2017

Seems to be patient ?
[Samsung Galaxy S8 & S8+ Cross Device Development] jesec:
1. I can verify that. I do have a HK variant of Galaxy S8. (SM-G9500)

2. Maybe you can just take a look at label on the back of the phone.

3. Idk. But HK variant should just be fine.

4. Nope. I do have HK variant. I think maybe older version of firmware or HK firmware doesn't support BL unlock so you have to upgrade to AQF (and maybe, Chinese firmware) before you can run CROM service. (note: Chinese variant can cross-flash stock HK firmware directly via Odin, vice versa.) As BL unlock is permanent, you can freely flash back to your firmware after unlock process is complete.

Actually I am using my U.S. firmware port on my phone and it works perfectly.
[Samsung Galaxy S8 & S8+ Cross Device Development] xdauser'17:
i really won't suggest you to buy a chinese s8. first, you can't get warrant on it if you are not living in china. in that case, it's much better to buy an international variant, because it has an exynos chip and it should be better than snapdragon. second, the china variant seems to have more issues. to be honest, i bought one s8, exchanged for twice. the first one's back glass was not installed properly, the lower-right corner is notable tilted, the second one has a dark line on the middle of screen, and the third one has a bright dot on the screen. now i have no more hope for the next one, and i don't want to trouble others any more, so i kept the last one. anyway, if you want to buy this only for rooting, you should have a good think.

also, i noticed my phone's otg is no longer working today. i have asked in another thread, and still waiting for answers. could the modified kernel be the reason?
[Samsung Galaxy S8 & S8+ Cross Device Development] kjames2001:
I have also noticed that the otg was not working, it was like the phony is not powering whatever was plugged into it, because no LED lit up when I plugged my stick or HDD. But when I tried again after some days, everything was just working fine. Lol
[Samsung Galaxy S8 & S8+ Cross Device Development] xdauser'17:
so now it's working?

i'm still looking for answers and so panic, because i already lost warranty. and now i just want to make sure my phone isn't broken.
[Samsung Galaxy S8 & S8+ Cross Device Development] kjames2001:
My guess is that there was water in the port, so the phone stopped outputing power for safety reasons. How long has it been for your case?
[Samsung Galaxy S8 & S8+ Cross Device Development] xdauser'17:
i cleaned it with water the day before yesterday, and now it's complete dry, because i can connect it to computer without any problem. only otg is not working, so wired...
[Samsung Galaxy S8 & S8+ Cross Device Development] hindutool:
Thanks for the update. this clears alot up. 2 More follow up questions then:

1) would you mind posting a link to your US firmware port on this message board?

2) Does your phone work with Verizon,? I saw in previous posts that you said you were going to use it with VZW, and then can we confirm that the HK variant supports the US bands? Is your US firmware port necessary to access said band?

I know some of these may have been answered earlier, but I could not get a clear answer from the posts, hence the reason for asking for clarification. We thank you again for all of your hard work.
[Samsung Galaxy S8 & S8+ Cross Device Development] kjames2001:
Hi jesec, I think I wanna try the hk firmware for the purpose of Magisk. Can you or someone provide a link for the AQF7 firmware hk version for G9550? Thanks!

---------- Post added at 03:56 AM ---------- Previous post was at 03:54 AM ----------

Yeah, that happened to me as well, but somehow it started working again. I guess you just have to keep trying.
[Samsung Galaxy S8 & S8+ Cross Device Development] xdauser'17:
haha, it's not a hardware issue. i restored to the stock rom with smart switch and otg is working again! HOWEVER, after i follow the guide in #3, flashed the kernel and magisk, it's no longer working... the rooting process is the reason. and then, i uninstalled magisk with the uninstaller, but it's still not working. so it's most likely that the modded kernel caused this.

[MENTION=6371894]jesec[/MENTION] could you please give it a try? thanks
[Samsung Galaxy S8 & S8+ Cross Device Development] Alcibiade:
Cool good to know the HK version is not stuck. Do you have a link to the Hong Kong AQF firmware for the S8+ ?

Flashing Chinese firmware over a HK one is problematic, it gets blocked. Actually how did you get to flash a Chinese ROM on a HK ROM. When I try it tells me it cannot flash a firmware without FRP on a firmware that has.
[Samsung Galaxy S8 & S8+ Cross Device Development] kjames2001:
Yeah, that kernel really just don't work for me. Good to see that I'm not alone. Lol so I know it's not just my device. Maybe after an update to the kernel and twrp, we will have everything working properly.

My S8 HK issue

That's great to hear. However,

1. I'm using HK version of the phone too but can't get past CROM error, I also tried CROM apk sent to me by one of our kind XDA friend that works with S8 China but still it gets stuck

2. This is my model . Can you share your exact model detail? It's worth it for me to get the exact same one and repeat the process

[IMG="My S8 info"]https://ibb.co/hBoHQQ[/IMG]

https://ibb.co/hBoHQQ

3. I'm rooting for that and I hope you or anyone here can help!

4. For some reason I can't flash chinese firmware onto HK S8. Is there a settings in Odin I skipped? Not sure about that

Very excited to see this baby being rooted!
[Samsung Galaxy S8 & S8+ Cross Device Development] Alcibiade:
All HK phones are in the same boat. Looks like the only way is to get the latest Chinese firmware flashed and then apply the guide. However the flash gets blocked due to FRP.

I guess we're nearly there. Jedec: how did you get the Chine ROM flashed on your HK ROM?
[Samsung Galaxy S8 & S8+ Cross Device Development] jesec:
To flash Chinese firmware to HK variant,

1. Make sure Google account and Samsung account are deleted. (alternatively you can factory reset your phone)

2. Re-partition option of Odin should be turned on.

Next time please report with details. Screenshot of error is preferred.

I will publish my U.S. firmware port if there are demands.

It works with VZW. U.S. firmware is not necessary for support to VZW network.

CROM Services has stopped

Hi, i am getting the error CROM Services has Stopped. my variant is SM-G955W Canadian....

Also, if the below process is only for Chinese/HK Variants, How do I unlock the Canadian G955W ?

Or is the bootloader already unlocked in this one ?

Pre - HOW-TO PREPARE FOR FLASH: (Chinese/HK variants)

SPECIAL NOTE: These variants do NOT have "OEM Unlock" option and you don't need to enable it. Only reactivation (Samsung Account) lock needs to be disabled.

1. On your phone, open Settings, go to "Cloud and Accounts" -> "Accounts".

2. Select your Samsung account, open menu, remove account. (That will make sure reactivation lock is disabled. Alternatively you can disable reactivation lock without delete your Samsung account. Result should be same. )

3. Download, install and run official unlock tool, CROM service.

4. Your phone is unlocked and ready to flash TWRP at this stage. Now you can proceed to part 1.
[Samsung Galaxy S8 & S8+ Cross Device Development] hindutool:
As we are getting more information on this issue I am updating OP in a text document for [MENTION=6371894]jesec[/MENTION] to review so that we will have a coherent set of instruction for this HK variant problem.

That being said, where do we get the Chinese firmware?

Is this the chinese firmware you speak of?

[Samsung Galaxy S8 & S8+ Cross Device Development] DonFFX:
I did, it won't work. TWRP can't be flashed until BL unlock
[Samsung Galaxy S8 & S8+ Cross Device Development] kjames2001:
Sorry, just saw your post now. Lol. Will try again. Thanks.

So do I still have to format data and flash the dm verity zip before I flash Magisk?
[Samsung Galaxy S8 & S8+ Cross Device Development] hindutool:
So this seems different from the method posted by [MENTION=6371894]jesec[/MENTION]. After you flash TWRP and select reboot recovery, it will boot into stock recovery and then you just let it reboot again into system from stock recovery? Is this fixed if you select the "re-partition" option in Odin as [MENTION=6371894]jesec[/MENTION] stated in a previous post? Again I am trying to come up with a coherent guide for everyone so any help or clarification would be appreciated. In fact, if any who successfully rooted their HK SM-G9550/G9500 could post their exact steps that would be great. I know @ jesec typed out a great guide, but now I am seeing all these posts that are providing variations on [MENTION=6371894]jesec[/MENTION] guide. Thanks!

Any confirmation on that Chinese firmware from my previous post?
[Samsung Galaxy S8 & S8+ Cross Device Development] xdauser'17:
no. you can just ignore that post, i wrote this by my own experience before jesec posted his guide. and jesec's is much better than mine.

to root you phone, the necessary steps in #3 post are:

part 1,

part 2 (step 1 -4)

and part 3.

i did not flash the 'dm-verity and force encryption disabler zip' at all. this nice guide worked for me almost perfectly except the USB OTG is not working.
[Samsung Galaxy S8 & S8+ Cross Device Development] kjames2001:
I have tried so many time with so many combinations of dm verify zip Magisk kernel etc, and nothing seems to make Magisk work properly.

I think the problem is still the recovery, twrp from op just won't boot on my phone. I'm using the twrp provided by xda member tomatolei, which is in Chinese only. And it doesn't seem to mount data properly. Because even after I wipe data, I still see my settings remained after reboot.

So I'll just wait for a new official version of twrp which I can boot on my phone.
[Samsung Galaxy S8 & S8+ Cross Device Development] Alcibiade:
OK, going to try it. Didn't know I could take a screen shot in download mode :)

Quick question before I get myself into troubles: the Chinese ROM you posted has English language option or not at all? (Feeling a bit worried to navigate in Mandarin...). Other question: does anyone has a link to the HK firmware for S8+? I can find the ROM for the S8 on sammobile but not the S8+ (And I am worried not to be able to flash back to the HK ROM once I flash the Chinese version)
[Samsung Galaxy S8 & S8+ Cross Device Development] kjames2001:
http://updato.com/firmware-archive-select-model?record=865544EA4FD911E7963AFA163EE8F90B

Yes, there's always English, you just need to know where to find it when you are using a language you don't understand.
[Samsung Galaxy S8 & S8+ Cross Device Development] xdauser'17:

Does the Chinese or HK variant allows to use an SDCard IF only one SIM is being used, or no SDCard at all?

The reason I'm asking is because I've seen a dual sim tray (Europe variant) and the top sim card slot also has an SDCard option as long as only one sim card on the bottom is used.

Also, could someone please confirm if both or only one of the Chinese and HK variants is fully rootable, minus the OTG support due to the kernel?

Does the HK variant need to be flashed with the Chinese firmware, unlocked, then flashed back to the HK firmware and rooted?

Thanks in advance.

I can completely confirm that the chinese variant can use one sim + one microSD, or two sim cards. and i can also confirm that it's rootable on my chinese SM-G9500. Plus, the jesec's modified kernel doesn't support USB OTG on my phone, while the samsung stock one supports.

The HK variant, I'm not very sure, because i don't have. Possible similar?

Just in case anyone is still wondering about The sm-g9550 s8 plus 6gb ram/128gb storage that I purchased from Amazon:

Out of the box with Chinese firmware and a Verizon SIM, I was 100% able to use the phone to make and receive calls, texts, picture messages and use data fine with verizon. I did not test volte or Wi-Fi calling.

I was also able to unlock the bootloader. I needed to flash the qf7 firmware with odin for the latest official 1.0.6 CROM to work.

I was also able to successfully install and use TWRP rev 1

But I am having a problem with flashing the semi stock kernel and magisk though. Everytime I attempted my phone work hang at the warranty bit:kernel screen and I would have to odin the qf7 firmware and start over.

Also something to note. My Verizon s8 plus scored 168000 at best fully debloated and the 9550 6gm ram model scores 174000 bone stock with no modifications:D:D let's unleash this beast!

I will say that the QF7 chinese firmware is a little annoying because some things are still labeled in Chinese (bootscreen/some apps) also this firmware does not come with any google apps. Not too too big of a deal you can download them off of third party sites.

Is it possible to just odin the latest Verizon s8 plus firmware on my phone now that I am unlocked and have TWRP?

Also Has anyone been able to use the 6gb/128 sm-g9550 plus variant with the jesec semi stock kernel and magisk?

I attached screen shots of the app phone info *samsung* so it looks like I may have a Chinese sm-g9550 unless flashing the qf7 firmware altered that:confused:

To narrow things down I did try:

Backup working stock boot in TWRP

Flash semi-stock kernel only **again this froze my phone on the "set warranty bit:kernel" screen**

Rebooted to TWRP and restored the stock boot

The phone works again with stock boot

So I am assuming it's just kernel related maybe because I have the 6gb s8 plus version:confused:
