i am going to be switching to tmobile from cincinnati bell, but cincinnati bell says they do not have a way to unlock the phone (which i believe is bs). my question is has anyone successfully unlocked their phone? i was thinking i could flash an unlocked rom but i couldnt find one. any help would be greatly appreciated!
bump. need asap please!
Just google "XT720 unlock" and pick from one of the many unlock services available.
Haven't seen any for free but they work, you need to provide your IMEI and will gt an unlock code back.
ps. The carrier can unlock your phone, they are just choosing not to.

Hi guys, I have been searching/googling/XDA'ing days and nights but found no direct resolution... please help....
I'm trying to root Galaxy S6 G9200 HongKong Dual Sim edition with CF-Auto Root but it failed and showed:
Installation Failure
You need to unlock your device to install a custom OS.
For information about how to unlock, please refer to your device information at www.samsung.com/cn.
Please press the power key to restart.
Can anyone please please please help?
Is it due to locked bootloader???
Yes, it is confirmed that the BL of S6 hk version is locked.
You could not flash the baseband and etc. unless you unlocked it.
Just a confirmation, are you having the S6 with version SM-920X?

That's NO good.
I'm having SM-9200.
is there a way to unlock the bootloader? I can't stay any day longer without root. Please help.
By the way , is BL lock indicated by the CROM SERVICE in download mode?

Try to press "shutdown" and "volume down" together while rebooting the device. It should present some information about the handset.
Is you device bought from China or Hong Kong/Macao.
In Macao retail shop, I check the S6 in "about device" of setting menu, it present "SM-G920X" which the shop sold it as model SM-G9200.
Could you help to provide the information in "about device"? Thanks.
For BL unblocking, try to follow the tutorial by searching S6 unblock bootloader?
I could not send link to you directly.
Hope it could help.

There's no unofficial (as in not via samsung) way to unlock the bootloader. If it were to be done, it would have to be through Samsung/the carrier you bought it from, which is highly unlikely seen as unlocking bootloaders isn't something samsung is known to do or advocate in any shape or form. Pretty much, it's locked permanently or it's unlocked. If they sold it as bootloader unlocked, you would have to take it up with the seller. And make sure it wasn't sold as "SIM unlocked" because that's a completely different thing obviously.
To give some context, for the galaxy S5 there was an almost $20,000 reward for finding a bootloader unlock. Link here. The best that could be achieved was root, and that was pretty difficult iirc. The Galaxy S4 had a security key that was estimated wouldn't be cracked until 2030, the only way around that was exploiting the security chain in the S4 boot. This wasn't possible on the S5 and, I would bet, isn't going to be possible on the S6

The model sold is exactly indicating G9200 in About Phone, yes it is a zero at the last digit.
It is bought from HK Samsung partnershop, not sim lock from any carrier.
the G920X from Macao is dual sim or single sim?

The G920X is a dual sim model which should be the same as G9200. I dont why it has different serious for same model selling.
From some of articles, lastest CROM service could unblock the S6 BL.
Just a warmly reminder, unblock BL would lose the warrenty afterwards.
Are you aware of this impact since you just bought a couple days ago.
If you do want to unblock the device without concern, could you kindly do me a favour for some verification on CDMA. Many thanks!:good:

I send a SMS for the unblock and root information of AT&T G920T and G925T.
It is found that there has a unblock bootloader version for SM-G9200. Please search within the website.
As per searching in the internet, SM-G9200 has China and Hong Kong version, both of them are using the same serious. Not so sure, some guys claime they are the same hardware and capability.
But the tricky thing is the China one support CDMA/CDMA2000 ( with 7 mode), however, the Hong Kong one (with 5 mode) does not, which indicates the HK block the baseband function for CDMA.
Therefore, that is the reason why I ask for the favor to flash the China baseband firmware on you HK device.

Well noted, I just assumed both G920T and G9200 are BL locked, but could unblock by using some tools.
Indeed, as per searched, it seems the thing is not working like that.
So far as I know, China Telecom are running CDMA2000 in China.
Well,
maybe is too late, but I've got a Samsung Galaxy S6, SM-G9200, bought in china, with the bootloader locked.
I was able to unlock the bootloader with this apk.
There are 2 apk-s, but I guess both are the same.
Maybe too late, but at least there you have for any other with SM-G9200 bootloader locked.
not same. s6-CROM.apk works.
unfortunately it doesn't work with my phone

I bought also a SM-G9200 in China. I tried to unlock with s6-crom and if I confirm that I will unlock I always get the message "Unable to open application Any unknown error has occured. Try again later."

Now I only get problems to flash the image. It always says Failed or stuck at NAND Write Start!

Hi everybody,
I followed this thread and used the S6-CDROM.apk to unlock the bootloader. It said "you can now install a custom rom". So I downloaded Odin and the respective files from "autoroot.chainfire" and tried to root my phone. Odin said "Success" but the phone was stuck at the boot screen with a message "Recovery mode not enforced" (or similar, sorry can't remember), and the phone hung completely. Fortunately I had installed "Smart Switch" from Samsung on my notebook and the "emergency reinitialization" worked and all my data and apps are still there.
For the time being I am done with root.
Keep up the good work guys!

That method is only for 5.0.2.
If you are on 5.1.1, you need to flash a custom kernel with root.

Hi everyone,
Di you find a solution ?
I'm a novice in the android but I got a Samsung Galaxy S6 Duos (China) SM-G9200 android version 5.1.1.
Baseband version: G9200ZCU1BOH2;
Build number LMY47X.G9200ZCU1BOH2.
Since one week I have tried to root and flash my device but it isnt work.
I have tried unikernel, TWRP, CWM but nothing.
Please can you help you have been in that situation.

My sister presented me this galaxy s6 phone from malaysia. I am from India when i inserted india sim card. I got the message network locked sim card inserted. I came to know from the internet all samsung phones are network locked, for that I have to make incomming or outgoing call for 5 mins. I inserted malaysia sim and (from india) made 3mins of call to malaysia and 2+ mins of call to my mobile in india. Inspite of this my mobile is not unlocked it is still locked. Please help me.
If i flash stock firmware from india will my s6 be automatically unlocked ??, without any side effects.
In internet I saw there are many sites which says they can provide unlock code but their charge is very high almost 50 USD. I have already spent almost 100RM for roaming calls. Please help in unlocking my phone.
Inserting the malaysia sim card will not work as the call has to be made through the network of the region the phone was bought. Using the malaysian sim in india is not enough as the call is still going through the indian phone network.
I already made a 3 mins call to Malaysia . Will it unlock if I ask to someone from Malaysia to make another 2 mins of call to me.
Only way to unlock a network locked S6 is to get the unlock code from your network or buy it online from reputable unlockers. Flashing ROMs will no remove the lock.
Suggest some reputable unlockers

The problem you may have here is unlocking services unlock the phone from a specific carrier. The region lock is not the same as the carrier lock that these companies provide a service for. A quick look on google brings up no results for region unlocking. At the minute your only course of action is take the phone to a samsung repair centre and hope they will remove the region lock for you.
I took my phone to local mobile service center and he unlocked my phone (dont know how he did) and my phone is now rooted. Now my question is, is the unclock permanent and can i flash stock firmware safely without getting locked again.
Please confirm

Sim Unlock is needed once in a lifetime and it`s irreversible. Anyway I don't understand why was needed to root your phone for sim unlock. Normally you can reset, flash anything now and your phone will be sim unlocked.
What do you mean by reset ? we cannot remove the lock by flashing a new ROM.
why dose it come up restart phone when i swich sim cards on my unlocked galaxy s6 eage and dose this lose all othe data and save picuters and contects
Please i do also have S6 brought from USA to Ghana and when i tried put on a sim, it said Network locked sim. please what should i do?
Hello community,
I´ve searched everywhere to solve this issue without success - I hope you´ll be able to provide a solution.
I´ve bought an unlocked S7 with Qualcomm/Snapdragon in the U.S. (no carrier contract) - I´ve used the phone for about 2 months with a U.S. local SIM card and everything worked fine.
Back at my homecountry I wanted to insert a new SIM from a local german provider but the phone refused to accept it.
Error message: Invalid SIM (please insert the UICC which came with the device) mhhhh, the device didn´t came with any UICC?!?! Looks like a simlock...
In several articles about the S7 I´ve read following e.g. "S7 will lock to a carrier once a SIM card is inserted" .... how can it be? I mean is it true?
So I wanted to root the device but I´ve noticed really quick that the Qualcomm/Snapdragon version has a locked bootloader, means root is not possible at the moment
Simple question
- Is there aaaany way to open/unlock the device to a new SIM carrier?
I just want to use my phone :crying:
Thanks in advance for your support.
Best regards

Hello MattBooth,
yes you did. I just received feedback from Samsung Germany and you are right. There is really a regional lock between US & EU versions.
According support team here in Germany I have to contact the region where the phone was sold.
I will contact the US Samsung support and chek if it is possible to unlock it. I will keep you in the loop.
By the way - I would still prefer a root solution...hope it will not take too long until someone will find a way to root a Snapdragon.
Other solutions are still welcome...go on with the tips :good:

Hello Major7070,
thanks for this very valid comment - I´ve never heard that a CSC can be flashed with a locked bootloader but if it is possible it could solve my issue...maybe at least :fingers-crossed:
@all, does anyone know if a CSC will help me in this case?
This is the current situation:
- Samsung Germany replied to my request following - yes, there is a regional lock in this phone, please contact the support of the origin country.
- Samsung USA replied following - there is nothing like a OEM regional lock in this phone - there is just a carrier lock by Boost Mobile, please get in contact with Boost Mobile
Boost mobile replied - we will help you with the unlock but you have to fulfill 3 requieremts:
1st - you need to be a boost mobile customer or former customer
2nd - the device should not be reported as stolen :good:
3rd - the device need to be at least 12 months old
I failed on requirement no. 1 & 3 - furthermore Samsun GER and USA gave contratict answers.
I didn´t even purchased the phone with a Boost contract - just used a Boost Mobile SIM during the three months.
The issue can not be caused by a carrier Simlock because if it would be created by it the phone would ask for the Network unlock code of each invalid SIM which is inserted to the device BUT it does not.
=> if this would be the case e.g. Unlockbase could help me with the issue but they can´t
OMG...I´m going crazy.
Thank you.

I'm interested to hear if you found a solution to this? I have a U.S. S7 and I want to take it to Germany here in a month. I've been trying to get a Sim unlock code here last night but haven't had a success through att. Have you tried purchasing a code from a third party seller?

After all this answers it's seems that your S7 is Sim locked. YOU should try an online service for sim unlock your device. There are several app on play store, about 20 usd for that and a code is usualy provided in hours. At least for europe. All the apps provide full refound if the code is not found. Search for imei unlocker or unlockscope in play store
Good luck!

Hello calinormy,
this were my first thoughts as well - but as I said, the phine is not asking for the "network unlock code".
I was in contact with several unlock providers and they said, that they can´t do anything for me as long as the phone is not requesting this code.
@all, I mean I´m willing to pay for such an unlock code...at least it is a try - but is there any way to insert the code via hotkeys if the phone does not request it?
Thanks.
Bye
Have you tried to factory reset the phone with the original sim inserted and then once complete insert the local EU sim? You might have to get a T-mobile USA sim to have the phone request a carrier unlock, not sure why that would matter but it's worth a shot.

Any idea how to solve this problem or should I open a new topic?
Thanks.
What does it show your imei as?
Sent from my SM-G920T using XDA-Developers mobile app
My guess is that you will have to upgrade to the latest ROM you already had installed. It might be that the IMEI cannot be read since that was upgraded with the ROM (and a downgrade of that partition will never happen)

Downloaded Frija , Flashed AIO CSC for U1 , (Somehow XAA always gives me error ) , wiped cache , factory reset still when insert sim shows me error.
Basic question:
1) Does this error means it is network locked ? When i go to Download mode it still shows Carrier VZW ? Where is it come from bootloader ?
2) If i root the phone (i dont care warranty)will it get rid of this ?any pointer will be big help

That's not possible. VZW does not sell unlocked phones ever. You might have bought it at a retailer like Best Buy?
It's network locked. You cannot root the phone (as far as we know). You can try the steps in the S21 guide you linked.
VZW's unlock policy is 60 days after activation. You must be on the U firmware and be running the VZW CSC.
Thank you for your response.
Yes , i bought the VZW unlocked from best buy retailer .

Where is the restriction coming from ? bootloader ?
It is a old phone it must be more than 60days for sure .

Have you ever activated the phone on VZW's network? If not, it will never unlock.

No , or actually i dont know since i bought it as aftermarket .
May i know , What are my options here ?
If i manage to put a VZW prepaid sim , will it get activated ?, and keep it for 60 it get unlock ?
Does that has to be new service VZW SIM , or i can borrow a friend SIM ?
I still don't understand where is the error coming from ? After 60Days will it have a OTA update to get it unlock ?
Its from knox itself. Any vzw sim should work
Thanks . i will try ship the phone to keep in VZW network in US .
BT W is there any way to bypass knox security (network lock check) or reimage knox and avoid the hassle .
also the same problem. Did you manage to solve it? only i have lg v50 thinq 5g
