Flashing d6616 baseband on d6633 - Xperia Z3 Q&A, Help & Troubleshooting

Can any one try flashing tmobile firmware baseband on the d6633.T-Mobile uses bands 2, 4, and 12*as listed here; 4 is the most widely used band for them. The D6616 model, which is the one specifically for T-Mobile, supports these bands. 12 is the newest band and possibly the least used. There are many phones already on T-Mobile that don't support band 12 because it's the band they recently acquired from Verizon.

I could be wrong but this seems like a recipe for DISASTER.

I agree, its probably not a good idea.

Actually I've flashed d6633 firmwares from all over the world on a d6633 just want those t-mobile 700 band fq on the 6633!

Flashing firmwares from the same model is one thing but a different sub model is generally not a great idea.

If you have a D6633 why don't you contribute to the community and try this yourself?

With se1000 on this, if you are so confident that it has worked for you in that past. Get the phone and flash it, then report back

Flashing another models firmware does nothing to add/remove bands. There is a thread somewhere on XDA about enabling additional bands for devices utilizing Qualcomm chips but root and unlocked bootloader are required.

Can i buy in china (during my trip) and install a Global ROM?

Hello everyone,
as per the title, can i buy the mi mix 2s in china from a local seller and then switch it to a Global Rom?
Will i encounter bands problem for example? i live in EU
Thank youu
Yes, you can just install the global rom, I'm living in germany and also got the chinese version. You may check what LTE bands are used in your country since the chinese version does not have all the bands the global version has. However, the extra bands the global version has are mostly used in africa and america so chances are good that you'll be fine
Are you entirely sure that the two versions come with different bands? I can't find any confirmation anywhere

Yes they do come with different bands. I do not recommend you buying the chinese variant!
Look for the model that ends with XA ! this is the Global one with all bands.
Trust us. There is a reason for different models to exist.
The Chinese model can install global ROM but you cannot lock bootloader afterwards so it is not safe and many apps will not work.
Global model has more bands than base Chinese models but same as 8/256 Chinese model.
You can, but it would be "better" to buy it and install a rooted ROM from here if you want full features like Android Pay to function.
You can't relock the bootloader if you change from the chinese ROM.
Yes you could, but that may be not suggested depending on the model you want to get...
For 6+64 / 6+128 models, China variant (XE model) differs from global variant (XA model): XE has less band support and you need to keep your BL unlocked to install global ROM. So you'd better not buy these two models in China.
Still, I can show you the missing bands on XE model if you'd like to know, but anyway I don't think it necessary to buy it...
For 8+256 model, there's no two variants, only one XA model for both China and other countries. You should be safe to buy it.
And, if you get XE variant and flash global ROM with BL unlocked, you still cannot install Magisk - you'll see bootloop and then enter recovery. That's another important reason why I don't recommend XE variant. The only way to install Magisk is to install MiPa kernel instead of the stock one.

Flashing Another Model's Modem ?

Hey Guys!
So I have just gotten an S7 (930S) and apparently, there is a mismatch between the bands present in the phone and the one offered by my network. I would like to know if I flash 930F modem on my phone would that be ok or not? I just want to flash the modem as well as the CSC of the 930F model. I hope someone can take the timeout to reply to my query.
Thanks

Yes you can, hardware is the same. However when you talk about network bands I assume your talking about the difference between networks using GSM and networks using CDMA? In which case you need to flash firmware which uses CDMA radios.

Well, when I am talking about Bands I am talking about the frequencies in which they operate. For example, my network offers the UMTS 900 frequency, but that frequency is missing from my current modem.
Therefore, I am assuming that if I flash the 930F model's modem, which does supoort the UMTS 900 frequency, I will be able to operate on the UMTS 900 frequency. Can you confirm me on that?
Or will I have to flash the 930F firmware on my phone to operate on the UMTS 900 frequency?

Yes 930F will work and install the radios you require.
The problem I am facing right now is that although the modem (Shannon335) on my phone (G930S - Korean) is the same as that on the international model (930F). But my phone (G930S) does not support one of the bands that my network supports which is UMTS 900 and that band is supported on the international version , although hardware wise (both are Shannon335) they are both the same.
So, I was thinking if i change my modem, currently its a South Korean modem and flash the international version modem could it work and make the band work for me?

Thank You very much.
I would also like to know how should I choose and which modem to flash on my phone. Which things should I match and what to avoid during the flashing process. I have currently U1 security level modem, so when I flash another modem should it be U1 level as well?

To avoid problems you must match the modem to the version of firmware you are using, so yes U1 to U1. Flash the modem separately via Odin

Conversion from SM-N986W to SM-N986U/U1: Still possible?

Hi guys, quick question... My good old Note 9 (Canadian variant: SM-N960W) is flashed with an unlocked/unbranded US firmware (SM-960U1), and everything's working flawlessly (Wi-Fi calling, VoLTE, OTA updates, etc.). The main reason I did it: Canadian carriers are useless morons, they take weeks/months to release updates, and I've been more than happy with the quick updates I get with the US firmware installed.
I would like to do the same with my Canadian Note 20 Ultra I will receive Friday, but I want to make sure it's still possible, with "Odin Patched", to flash a firmware from a different region on the Note 20 Ultra.
Someone on XDA did it? Did it go well, and did it break something?
Many thanks

I haven't seen anyone do it yet, you can test it out for us and report back how it went.
I too have a Canadian variant of Note 20 Ultra...wondering if switching to the US ROM will enable rooting option?

Thanks for the heads-up, I didn't thought about 5G, but glad to hear it's still possible to do it (flash a firmware from a different region) without bricking the device. I'll probably pick faster updates over 5G for now, considering I live in the middle of nowhere and have access to LTE only anyway
I have a Rogers Note 20 Ultra, I will wait for the updates because here in this part of Ontario, has 5G for whatever reason. I really enjoy streaming Xbox games from the cloud. Almost no delay.
You should be able to flash U or U1 firmware using patched Odin. Just make sure if you have a carrier locked version (not sure if thats a thing in Canada) to have it SIM unlocked before flashing anything, especially if you plan on changing carriers ever. After going to U1 firmware, you can access the service mode menus to enable bands for LTE, NR 5G and DSS. Canada uses 5G bands n38, n66 and n71 and DSS. The only band I don't see available in the US firmware is n38, although it may be available under another CSC like WWD or GCF. I have included a screenshot of the bands I've enabled under the Verizon CSC.
Has anyone with an N986W been able to flash the U1 firmware yet?
Has anyone tried it already? if its possible to flash SM-N986W to U or U1
Did anyone flashed SM-N986W to u or U1. Can you share the experience Please.

This can be fixed by flashing the home_CSC file of your carrier and then there are many other ways to fix this. So take this information lightly.

What he said :good:. Also you would be able to get on Beta on which a lot of 5G things were fixed / enabled so in fact that might work for you.
Only things i would want you to check before flashing the US firmware is:
1. Is it a dual sim phone? If No you are good.
2. Do you have E-sim Capability enabled? If No you are good.
3. What variant is your phone ? If Snapdragon you are good.
ohh if you are flashing US firmware flash the U1, no need to flash U firmware. Do check if you are sim unlocked because in case you are not and in future you want to sim unlock your device you will have to be on Carrier Firmware, if you plan to stay with your carrier for a long long time and or if you are sim unlocked this should not be of a concern.

Just as a heads up for future reference all Canadian new phone since December 2018 are Sim unlocked
For anyone still wanting to convert their N986W to US unlocked N986U1 I just wanted to say its possible. I used modified Odin and put the U1 firmware on my N986W. I was then able to install the 3 beta's. After a couple of days I switched back to the Canadian firmware. So for anyone wanting to try it, you should be good to go.

Hello,
I have a n986w (freedom locked) and i was wondering does every band work with u1? Or do we have to manually enable bands from service mode? And if i may ask where did you find modified odin and u1 firmware? And why did you roll back? I am still new to samsung phones, i had my fair share of modding android in past but sammy does thing bit differently so i am but confused about everything

Your N986W with freedom is probably not sim locked. I know mine isn't and someone earlier in the thread said that phones in Canada aren't sim locked anymore. So you should be able to proceed. When I switched to the U1 firmware I was receiving LTE signal on freedom. I did not test any other bands as I was just in my living room. There is a guide here on xda regarding enabling all the bands and there is a link to it from the thread I followed in order to switch to the U1 firmware. The link to modified Odin and U1 firmware is also in the same thread. The thread OP is warriorvibhu and its about switching from U to U1 firmware but you can follow it just the same and you can find that thread and the thread for sideloading the beta in the Guides, News and Discussion section. Sorry I couldn't add a link for you I have limited time right now. I rolled back because I just wanted to see if it could be done or not. The instructions were straightforward. Good luck and enjoy.

It did not trip knox as its official firmware. You will have to manually flash the betas. Also, when you get the U1 firmware, make sure that you download the one ending in ATID. That is the one required for the beta. I read both the guide for the beta flashing and the guide for flashing the U1 firmware before I proceeded. Also make sure you remove sim card b4 flashing U1. Have sim in when sideloading the betas and be careful you don't accidentally take an update between U1 and beta or you will have to re-flash ATID.

t-mobile version

Is this the latest version for my device? I see people on 11 stables or betas but haven't seen anything for my device. Any help would be appreciated. I included a pic of my latest software.
This is t-mobiles latest stable. Global model has android 11. If you follow the threads to convert to global, just be aware that the global android 11 doesnt pick up sprint bands yet.
T-mobile is slow on its updates...

Question Flip 3 5G F711U1; XAA => INU

I have got a Samsung Flip3 US unlocked version. Have been using it outside US with and Indian SIM card from last few months without any hiccups. With Samsung Pay working as well.
Now, with the release of 5G services here in India, I'm not sure the bands that Indian operators use are unlocked or not in this. Jio (Indian service provider) says that you're using a non-5G device.
So, I was wondering if I flash an INU firmware to my device. Will it unlock the bands and also let me get OTAs from Samsung? Maybe if someone here did this already?
(According to Jio, this phone is compatible with their 5G network. Also, checked on gsmarena, the international version has the bands that JIO supports.) Since the chipset in international and US is same, I suppose the bands are already there in the device.
Thanks in advance for your help and comments.
Hi Jatin, I don't think flashing your US flip 3 with IND firmware, will fix your problem. The IND firmware is for the F711B model, you are on the F711U1 model. I would not try that. A lot of the F7711B firmware are multi-CSC, but not for the U1 model.
Thanks for the reply, @slysurfer.
I was thinking that since both F711B and F711U1 share the same chipset (Snapdragon 888), the F711B firmware drivers will work on F711U1.
I read some other posts in here (on XDA itself) in which someone with an EUX variant flashed INU firmware to it. Not sure the EUX variant is multi-CSC or not.

Yes, the EUX variant is multi-CSC (to a degree) I can flash any firmware from Europe to South East Asia, but as mentioned we can't flash any firmware from US/Canada.
Big >IF< you can OEM unlock the bootloader you can install twrp and disable the vbmeta and flash a U firmware over a U1 phone and visa versa. But even if you can do all of that it probably still won't work. Personally I'd take it to my local mobile phone stall and see if they can do it.
Thankyou @beanbean50 for your answers.
Sorry for the noob question, . Earlier when Samsung used to release 2 different hardware versions of the same phone like one with Exynos and other with Snapdragon, flashing the other region ROM was not possible.
So, I was just wondering, since both the regions (US & South East Asia) has the exactly same hardware, the networks bands in both of these must only be software locked. Thus, since the US version already has the hardware, can't simply flashing a different region ROM should work.
Again, if there are some other locks that prevent this, it's not possible to flash. Just like if on paper both devices are same, the only difference they have is, they are released in different region.
Also, I checked, both are also manufactured in the Vietnam.

There is not OEM unlocking in under developer options. I have through other posts and things on how to unlock. I suppose it can't be unlocked in a straightforward like F711B can be.
I suppose this is the hard-stop that cleared my doubts.
Thanks one again, @beanbean50 for your time and answers. Really appreciated!!
P.S.: If you or someone you know have some experience unlocking a US snapdragon Samsung device bootloader, please do share. I might have to consider unlocking bootloader in the future.
