Use stock rom india openline firmware

@Sheepmister thanks for the response, I couldn't able to find the right link. Please can you help me?
Appreciate quicker response.

@Sheepmister I have downloaded the firmware https://www.sammobile.com/samsung/galaxy-a12/firmware/#SM-A125U with the country as Unknown, flashed with ODIN still the phone is in Network Locked state. Please help me if i am missing anything here. Thanks

Your bootloader is unlocked, or not?

Network lock will not able to fix by flashing simple rom
You need to spend few credits by chimera tool and get it unlock

You can flash a125w xas firmware on the u version so you can unlock bootloader then flash a125f firmware for your country after unlocked bootloader. This requires taking the phone apart and using test points for brom. I do not recommend any tools that force brom without test points bc it bricks it(personal experience with mtk meta tool)

Unlocking the bootloader and flashing different firmware does not automatically also network unlock the device. So this is very bad advice for the original poster

if the firmware is unlocked from factory then you can. For the states i use canadian xac firmware to unlock everything and it works great. No bloatware either. The a125u that i converted was locked to tmobile. Now i can use whatever.

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?

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."
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.

It should be under the Verizon model. Usually tracfone does not lock the bootloaders on their variant. On another thread a guy flashed the verizon firmware to this model with no bricks and issue. but doing that WILL lock the bootloader. I hope he responds to my post. want to know to what extent it was flashed and if knox got tripped.

I should be able to get one of these mids august hopefully and will use it as a test device to see what bricks it and what hack can be done. In the past tracfone has release the SM-S975L(Tracfone Unlocked bootloader) which equals to an SGH-I337 (AT&T Locked bootloader), they released the S5 & S6 which equal to the SM-G900V and SM-G920V, both have Unlocked bootloaders. So i dnt think the S7 is any different and equals to the SM-G930V. Any root method that works for the SM-G930V should work on the SM-G930VL. But again this is just my say based on past experiences, i wont know until i get the phone and try all this. For what I know so far he was able to flash the complete verizon firmware which i think will flash a locked bootloader and no going back after it.
Yes will share my experiences.

So i was able to flash the full latest verizon firmware and fully ended up converting the phone to an SM-G930V. SO provided that you flash the firmware on which root was achieved for the SM-G930V, then there is really no stopping you from rooting this phone. As expected due to flashing the verizon firmware the phone has a locked bootloader now but root was achieved regardless.
Proceed at your own risk.
I have the Sm-g930vl (tracfone) and would like to confirm the bootloader is unlocked. I can boot into both recovery and download mode but cannot connect with fastboot to get device info. Is there another way to check?

^This. You need to sim unlock before converting to international, or you will be unable to unlock the bootloader and have OEM unlocking. At least until they fix the MSM to be able to skip sim unlocking.

Yes, you can try it that way. If the device is already fully paid off you can also simply contact Tmobile and they will be able to sim unlock it for you already as well, or if you haven't paid off and want to chance it, you can try contacting them on twitter or through the tmobile app and try to get the customer service rep to unlock it. Though if you haven't paid it off it's probably easier and faster to DM the OP from that thread.

I have the international version and am also stuck with the greyed out OEM Unlocking option. My bootloader is also still locked. Any help would be very much appreciated. I have tried using fastboot to oem unlock but I get this error
FAILED (remote: Please enable OEM unlocking in developer options first)
finished. total time: 0.007s
It was on a Chinese ROM before and I did use https://oxygenos.oneplus.net/Fulldowngrade_wipe_18821_190425_0253_user_fix_revision_MP_release.zip to downgrade so I could switch to the English ROM.
I also have a one plus 7 pro. It has been carrier unlocked but still the OEM unlock is greyed out. It is running Android 10. Is there a way to 'ungrey' the OEM unlock option? Thx
Do a search for this "The T-Mobile OnePlus 7 Pro’s bootloader can be unlocked by flashing Android Q" and fallow the instructions. Instruction are on xda.
There is no need to unlock the sim on the T-Mobile phone to unlock the bootloader.
Phone needs to be on the international firmware. This can be done with the patched msm tool. Then downgrade to android development preview 3 using local upgrade on phone. Unlock via fastboot and finally root and install a working rom or do the rollback to android p via local upgrade. Search for the guide and fallow the instructions. It really simple.
Kind of related. I converted my t mobile oneplus 7 pro to the international version and am eligible for a sim unlock. I tried to do it over chat but they said since it's not their version of android I would have to do a factory reset (which wouldn't convert it back to t-mobile stock) in order to sim unlock it, does anyone know how to sim unlock it on the international version with t-mobiles help. I would have thought t-mobile could just do it on their end but I guess not, and I guess they are kind of idiots over there to, because initially they had no idea what i meant when i said i converted it to the international version (heck they still didn't understand that I changed the firmware/ROM) so resetting it wouldn't make it a t-mobile phone again.

Question Is the SM-A125U different?

Is my A12 (a125u) different and unable to be bl unlocked/rooted, etc? It has OEM unlock in dev options....?
Did you figure this out? Looking to do the same... Also can't find a firmware for it, please share what you did if you had success. Thanks!

Yes, the A125U has OEM UNLOCK in the developer options......you can turn that ON by going into : settings > about phone > software information ...and then tap BUILD NUMBER several times until you see that you have enabled "developer options". Then you go into developer options and turn on OEM UNLOCKING.
Before updating firmware recently OEM UNLOCKING was greyed out. But now I can switch it on. Now the question is, can this variant be properly bootloader unlocked and rooted. The known repository for downloadable firmwares for Samsung phones DOES NOT seem to have this variant firmware for download. And I wonder if that is required for this to be properly rooted.
Galaxy firmware has the firmware for this variant. I have the att version and I can't seem to unlock the bootloader. Holding volume up in the download screen does nothing. Any luck?
Bump, I have all same questions.... Anyone figure anything out?
Before I had tmo Sim unlock my phone the I set the oen unlock to unlock now its not there at all
Anybody rooted this yet ?
anyone know the interchangeability of the firmware between the a125u and other versions
I wish to know as well
What if the OEM unlock not showing how do you get it to show

I'd like to know this too. I believe the internal are all the same for the MediaTek devices. I got a SM-A125F for free and want to use it in the US. It looks like I could if I can convert it to SM-A125U or MS-A125M. I already bricked it once trying to flash U firmware and has to flash back to F

I have a similar issue but vice versa. I bought a US version (SM-A125U1) only to find out months after that the dual sim option is locked and i think the only way to unlock it is changing the firmware. Now I need help to know what I can do to, please.

Thanks for the info.
-Was there an "OEM UNLOCK" option in the Developer's Options?
-What did you do in DOWNLOAD mode to unlock?

Can't unlock T-Mobile device network

Just a noob question?
Long story short I haven't had success unlocking T-Mobile..
I think I can unlock boot loader with msm tool.
My question is if I successfully unlocked Boot loader and flash any custom ROM will I be able to use any SIM?
Thanks

Does this method void warranty ? My one plus 8t is less than a month old?

Yes, your warranty will be void but unless you're really rough physically with your phone, there's almost nothing you can do to it that the folks here at XDA can't fix!

If nothing else, you can always use a separate MSM tool and revert it back to the T-Mobile version. No harm, no foul.

I think I read something about using MSM tool to flash EU or GLOBAL firmware and not need to request unlock code (which voids warranty) because I can unlock boot loader on the spot.
Can I revert to T-Mobile firmware with locked boot loader just I case if I have to return it for warranty
Thank you very much

The link I provided will convert your T-Mobile version (KB2007) to the EU version (KB2003).
If you need to go back to the T-Mobile version, there is a separate MSM tool to do that, it will also relock the bootloader at the same time for warranty purposes.

Another question
Can I convert T mobile to global firmware directly or is there any special process?
Thanks
Use the link I sent you. That will convert it to the EU version. Setup your phone using just the defaults. Then download Oxygen Updater from the Play Store and within the app you can choose what version (Global, India, European) you want to install/upgrade to.
This is the link to the T-Mobile MSM Tool: https://forum.xda-developers.com/t/...l-to-restore-your-device-to-oxygenos.4180981/

T-Mobile to Global (USA) Firmware8t+ 5G
I just got my unlock stuff from OnePlus and I know there is a thread on here for converting but from what I see it is to go to EU firmware and has some other steps I assume that are for rooting. I don't want to root I just want to install the USA...

Flashing to a different firmware does not alter the SIM lock/unlock state. If your device is SIM locked to T-Mobile, it will remain SIM locked to T-Mobile after flashing to the Global, EU, or other regional firmware. T-Mobile devices can only be SIM unlocked on the T-Mobile firmware.

So in other words T-Mobile Sim can be unlocked only if I flash to Global or EU T-Mobile firmware?

No. You can only SIM unlock the device on the T-Mobile firmware. Flashing to EU or Global only allows you to unlock the bootloader.

You need to meet the SIM Unlock requirements for T-Mobile to process the SIM Unlock for the device Then using the T-Mobile Unlocking app, go through the steps and select Permanent Unlock. If it completes, the device will restart and will work with any carrier SIM.

If T-Mobile doesn't want to unlock my device. There is no other path? I have tried a lot of times with a T-Mobile rep they say it wasn't purchased at T-Mobile directly. Please help?
Thanks
I think they are websites that supposedly unlock Sim or devices.
Any ideas on that?.

Try some of the third party unlocking services locally in cellphone repair shops or the online remote unlock services.
