Can you explain to me then how can I help?

I cant sorry. Ive just been a guinea pig trying out as per first page and waiting patiently for it to work properly. I think both @baskaflyfer and @otonieru are close however.

 

[moti2408]

please kindly help us by sharing your full QCN dump, you can do it in PM, so no personal info is shared,

how to do so :

instead of choosing "Restore" in QPST, choose "Backup" instead, and save/backup your QCN in two formats .qcn & .xqcn (xml)

save it & upload it somewhere and send me and baska the link

this way, i and baska can work and comparing the value in US model as well

I could not save it as .xqcn
if you can explain how

I have A3000 - US version, I want band 3 LTE while keeping my original IMEI. Do we have a way for doing that?

 

[serge766]

@otonieru by using the band 5 band 8 unlock from baskaflyfer my handset A3000CN couldn't connect to band 3 lte anymore, my default provider using this band. Is this also happen to you when you confirm that band 5 and band 8 unlocked.??

 

[dipka]

Band 28

Can somebody confirm if they got band 28 working for the 3t American version? I belive it's GSM apt 700..

I have A3000 - China version, I want band 20 (800 Mhz) LTE while keeping my original IMEI. Can you help me?

I used the qcn provided for band 3 unlocking for the us a3000, and it didn't work. I then checked in dfs and didn't have band 3 unlocked. So i unlocked it, rebooted, yet still I had no band three.
If you think I may have used dfs tool the wrong way - I used it the right way. No point of asking. I already managed to *supposedly* enable bands before.

have you by any chance, changed ROM ? if u ever change rom, you gonna need the rmt_storage to be patch again,

else, anything you do wont written

no,

VoLTE is a whole different matter,

there are a lot of NV values related to VoLTE in our QCN, and each carrier will need different config,

normally the config can be pushed through network, when you connect to your carrier network. but for some carrier, it simply doesnt work,

not to mention, on some ROM, even the IMS_enable (VoLTE will need the phone to be able to connect to IMS, thats the main prerequisite) value is still "0", thus it wont even try to connect to IMS

what carrier are you on? T-Mo ? Jio ?

Wow thanks for your reply. I tried to contact one plus and they said they won't support my carrier but will support another. I'm in Hong Kong. They support China mobile but not sun mobile. I tried to enter engineering mode to enable volte but the option to enable the enhanced 4g never showed. Also tried to fix the apn and add the one suggested by carrier with no effect.

Haven't changed ROM or flashed anything. But I'll try re-flashing the patched rmt_storage and update you guys.

I have done the steps above, but I found my CDMA sim card can't use. When I insert the CDMA sim card, it's still no singal. When I want to change the network settings, my phone restart.
Is there any way to solve this problem? Suppotr CDMA network is very important in China, due to China Telecom still haven't ran a Volte network.
My phone is A3000 Chinese variants.
Thx.

Yes some frequencies don't work, I'm trying to find solution. After the holidays I will test all their achievements. And i'll explain what and how to do.

Op3t a3010

You guys are so awesome! Hope you will fully succeed. I'll get my Oneplus 3T A3010 soon and will be open for any experiment to get Band 20. :good:

Have you tried it yet?

Im holding to purchasing a chinese a3010 just because it doesn't support band 20 which is essential for local carrier.

Correct me if I'm wrong a3010 is 3t chinese right?

10. Rmt Storage Patch Zip
What about op3t patch?

The OP specifically says in the first bunch of words, "...for the OnePlus 3." If this was for the 3T, someone would make a subforum for it in the 3T section.
