Checking whether bootloader is locked, and unlocking it? - Galaxy S6 Q&A, Help & Troubleshooting

Hello,
I've searched through xda and other websites but couldn't find a proper answer -- my apologies if this was already asked and answered in an existing thread.
I have purchased a S6 from Amazon, but the device is branded with Swisscom, with an awful boot logo and sound, and a few specific apps.
I'm waiting for a nano sim, so for now I don't know if the phone is also simlocked.
I intend anyway to install custom roms, so I don't care much about this, however I can't find out whether the bootloader is locked or not (in which case, I'll have to send it back to Amazon I guess).
Can someone assist with this? The device is a SM-920F, I made the OTA update to 5.1.1 upon powering it (which might have been a bad idea actually, from what I read later..). Not sure what the bootloader and rom exact versions are, but I will add them to the post if necessary.
Thanks in advance!

Yes bootloader is unlocked. As far as which firmware you can use, you'll have to wait til you find out if its an international unlocked G920F. If so, you have many firmwares to choose from, just Odin and boot. Then recovery and factory reset and your CSC codes will all be lined up (that's just what I do) and happy flashing.

Thanks for the feedback.
Just got the nanosim, which registered just fine on Orange France, so the device appears to be unlocked and operational.
I'll proceed with rooting etc. in the coming days.
Cheers

[Q] Need to restore to stock in order to RMA

Hi all, any help would be much appreciated.
I'm from Canada and bought the HTC One S from Expansys a few days ago. It was compatible with my Rogers network, however, I JUST switched over to Bell and unfortunately, this version of the phone, while unlocked, is not compatible with Bell's network. As a result, Expansys has agreed to let me return the phone, however, during the short time that I was using it, I had rooted and installed a custom rom (WITHOUT backing up the stock; boneheaded move, I know). The phone seems to be the European version from France, so I was thinking of restoring to this: http://forum.xda-developers.com/showthread.php?t=1543588 however, I remember reading an article on Rootzwiki about how our phones are marked once we unlock the bootloader. Is there a way to remedy this? I'm afraid Expansys will reject my return if they notice that I've "tampered" with it and would like to return it fully to stock, unrooted, completely original everything.
Again, if anyone can direct me how to proceed, I would be so grateful. I have two weeks to send my phone back.
Thanks guys!
Thanks
I would love to know the answer to this as well. Kinda in the same boat...My main concern is removing CWM..Anyone have any info on this?

Based on all my readings thus far, it seems removing the "tampered" message is not possible yet.
In order to remove CWM and revert back to stock, I recommend hasoon2000's All-In-One Toolkit: http://forum.xda-developers.com/showthread.php?t=1604677
There is an option to flash the stock recovery.

You can just do the following:
Remove root - can be easily done via superSU app from the settings menu, where is mentiones full unroot
Flash stock recovery
Relock bootloader.
After that if you want, just find the correct RUU file for your phone it it will flash it. The word tempered will go away, but it will just say "relocked"
I don't think that expansys will access the bootloader to check....Most employees are not tech savvy...As long as they power the phone on, without problems....you should be fine.
you will always see the brand relocked. untill we have al full s-off it wil be like this always.
just flash the correct ruu it came with,
if the phone works normal they wont have a reason to look at the bootloader.

Locked Bootloader?

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?

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."
EDIT: This problem is solved. Had to sign in at Samsung Account firstly.
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.

[Completed] Unroot HTC One M8?

Hi guys, I've googled high and low and I can't seem to find anything that I a)understand or b) feel is relevant to my situation.
I bought a HTC on ebay, it arrived, I put my sim in and realised it was rooted. The phone doesn’t work on my network, I knew this when I bought it so I bought an unlock code but due to the root, I can’t seem to enter it, it just says no sim inserted.
Ideally I’d like to remove the root, I’m not a technophobe and learn pretty quickly, but I just don’t understand all these different versions of firmware etc.
I followed the unlockr guide and found out my CID is VODAP001 but the main-version is blank so I don’t know which roms or what have you to download.
I’d be happy leaving the rooting as it is if I could enter my unlock code, but I can’t figure out how to do this either. Is anyone able to help me? I don’t know what’s been done to the phone, the seller is ignoring my messages, I can’t return the phone as I (stupidly) missed the description where it stated the phone is rooted.
If it helps, it says im using cyanogenmod version 13.0.201xxxx and I've seen TWRP when booting to recovery mode etc. I've downloaded a few files, used an all in one mod or something from hasoon but as yet, the file system is unchanged.
I've seen something called sunshine which apparently unlocks to any network but as I've just forked out £100+ for the phone, I don't have the £25 the guides say it charges to unlock
Thank you in advance.

SM-G970U with SM-G970F FIrmware?

Hello All,
Ok so first off you guys at XDA are the ****! I swear I can find anything I need to know on this site with a little research, much respect. So as the title suggests I wanted to know if it's possible to flash a SM-G970U (US) with SM-G970F (UK) firmware? I am basically looking for a slightly less complicated way of enabling "OEM Unlock" to Unlock the bootloader. And yes I realize that more than likely I will not be able to use any US sim cards with that firmware but if it is possible and I could unlock the bootloader I could basically load anything I wanted onto it right?
......actually seems like the SM-G9700 would be a better candidate for the firmware to load on the SM-G970U.
.....be gentle, I'm a N00B...kind of =\

Actually i want to know as well because i read somewhere where someone said its possible because they are all the same models........did it work for you?
yea no...don't do that it won't work
Lol i already tried it flashed succesfully according to odin but when the device rebooted it came with the same firmware before and nothing changed Lmao
how did it flashed ,please specify
I was told this is not possible. Unless you can find original overstock (i.e. that has NOT been updated) in which case you can pay to unlock the bootloader.
Otherwise, I believe any bootloader beyond v1 cannot be bootloader unlocked. Only hope is Sammie does us a solid when this goes EOL and unlocks the bootloader. Question is whether VZW and AT&T will prevent them from doing that.
My S10e is still going great, and if I could root and flash a custom rom I'd probably replace the battery and roll with it another 3-4 years because I have no interest in the larger phones that dominate the Android market now.

Flashing LineageOS for MicroG on 8T (T-Mobile Variant) purchased from OnePlus

Hello all!
Thanks for taking the time to click into this.
About me: I mostly see myself as a somewhat tech-savvy noob - I have rooted several devices in the past, flashed ROMs, etc.
New Device: OnePlus 8T T-Mobile Variant purchased from OnePlus.com
Condition: Brand New - never started the device
I would like to essentially imitate Calyx as described here.
=> install TWRP/Magisk + flash 'LineageOS for MicroG'
Questions:
1) Will I be able to unlock the bootloader given that this is the T-Mobile variant purchased from OnePlus?
2) Do I need to take additional steps because this phone is the T-Mobile variant?
3) basic question: I have never started the phone so it has no personal data - should I back up the current setup in case I need to return to OOS for any reason or can I track down the default OOS installation making that all unnecessary?
(I remember in the past default Samsung installations were easily tracked down and flashed using Odin).
4) Would you recommend any detailed instructions to go through the process of backup, installing custom recovery, accessing root privileges, flashing LineageOS for MicroG, etc?
(I feel like I am piecing parts together from different places and it's all not fitting together)
Thank you so much for reading this.... I feel like I'm going down several rabbit holes currently so any perspective or support is welcome!
It would be helpful to hear any thoughts from some more experienced peeps before I move ahead.
Thank you!
Currently, I am trying to get the SIM unlocked, then unlock the bootloader, and proceed with the plan above.
I am considering returning the phone and getting a different one that has more users on XDA to avoid having bizarre issues arise with the steps involved with the T-Mobile version of the 8T and being totally on my own.

whoa! that's helpful feedback. Thank you for posting!
Based on your comment, I am leaning towards returning the phone.
I think I learn best through examples and may need a little support.
I am now wondering how I can figure out which phones have the largest 'community' on XDA.
I have the T-Mobile variant. There's more support and options available so don't be discouraged.
Normally, you have to be SIM unlocked before you can do anything else, like bootloader unlocking. If the phone is being paid for or financed and you haven't been a long time customer you may or may not get it SIM unlocked.
That said, I got mine SIM unlocked after contacting the T-Mobile Tforce people on Facebook. Then I saw this thread on Rebranding the T-Mobile variant.
[GUIDE] Convert TMO to EU via MSM Tool, no SIM Unlock or Bootloader Unlock needed!
*** Use this at your very own risk. *** You will lose all data *** Backup your working modem and persist, just in case *** Read the entire post and follow the steps closely before asking for help. Post all error messages and steps you took...
forum.xda-developers.com
Following it I changed the T-Mobile firmware to the European firmware. If nothing else you get more recent updates and a local update feature (full OTA updates can be downloaded and installed locally). As a result of the conversion I was able to simply fastboot unlock the bootloader without need for waiting for a code from OnePlus. The phone is now bootloader unlocked and rooted with Magisk.
Note that according to the OP, SIM unlock is not necessary for the conversion but you'll still need to be SIM unlocked to be able to unlock the bootloader.
Now that I'm "free" I now have the itch for a custom ROM. Over the years all of my devices run either with microG or just UnifiedNlp but no Google. I feel the need to do the same here. Currently I just have most Google apps disabled and using FOSS apps in their place but still...
Besides LineageOS for microG, the 8T also has Carbon ROM and crDroid. They historically have always had signature spoofing support so I assume they still do with Android 11. That means microG can be used.
Check the guides and ROM/Kernel threads for more info.
I don't know if I can get to trying anything this week but I hope to. I work at a drive-in movie theater and with Spider-Man coming out this week I'll be quite busy.

Following it I changed the T-Mobile firmware to the European firmware. If nothing else you get more recent updates and a local update feature (full OTA updates can be downloaded and installed locally). As a result of the conversion I was able to simply fastboot unlock the bootloader without need for waiting for a code from OnePlus. The phone is now bootloader unlocked and rooted with Magisk.
Note that according to the OP, SIM unlock is not necessary for the conversion but you'll still need to be SIM unlocked to be able to unlock the bootloader.
Now that I'm "free" I now have the itch for a custom ROM. Over the years all of my devices run either with microG or just UnifiedNlp but no Google. I feel the need to do the same here. Currently I just have most Google apps disabled and using FOSS apps in their place but still...
Besides LineageOS for microG, the 8T also has Carbon ROM and crDroid. They historically have always had signature spoofing support so I assume they still do with Android 11. That means microG can be used.
Check the guides and ROM/Kernel threads for more info.
I don't know if I can get to trying anything this week but I hope to. I work at a drive-in movie theater and with Spider-Man coming out this week I'll be quite busy.

Excuse the late reply.
No, not too versed on this device really. I searched for that error and got a lot of hits but didn't have the time to read up. Sorry.
