What about indian k20 pro, I have ordered one to a friend there

Does it support B20 LTE or will it be the same as the chinese one

News just arrived today that Mi 9T PRO will arrive to europe on 20th of August
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] Guido83:
no B20 on indian k20 pro. for this you have to wait for the mi9t pro
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] gurwinderr84:
Please, can you tell is it possible to B20 on Indian k20 pro and How??? Please elaborate the whole thing and process???
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] nosidefcp:
Any updates? This would bem gold
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] gurwinderr84:
So, we can get B20 on our device??? How to do???
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] ef1x:
Yes you can buy mi9t pro to get b20 in just a couple of days. :p
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] gurwinderr84:

Solution???
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] ef1x:
Sell k20pro buy mi9t pro thats the only solution for now. Or wait for devs to see if there will be chance to unlock b20 when they get hold off mi9t pro device and rom. Im in the same boat as you.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] gurwinderr84:

No it is not possible to unlock lte band 20.

[MENTION=7911954]Robbo.5000[/MENTION] Hi Robbo, what about the official global rom for the upcoming 9t pro? When will this be shared? Will it work with all the ram/storage options? I d like to flash my CN but I don t really want to go custom. Thanks in advance.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] Robbo.5000:
It's going on sale in the Netherlands in 5 days time. The global ROM should become available at that time. The global ROM should work on a Chinese phone. However it's likely that you wouldn't be able to lock the bootloader after flashing, as it will brick the phone. Flashing the global ROM will not unlock the bands that will be on the global phone. I've never heard of any phone getting radio bands unlocked after flashing an official ROM from a different region, so this will be no different.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] Dorian.:
Thanks Robbo.5000, yes I know it won t unlock the bands but I think I will prefer the global rom. I ll leave the bootloader unlock, it won t make any difference to me.

Don't let this thread die!
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] dev-DaT:
What exactly is the limiting factor here?

If i would flash the european (mi 9t pro) fastboot rom on my k20 pro. Would'nt that unlock LTE band 20? or is there a hardware switch that detects whether its k20 pro or mi 9t pro that blocks the unlock of b20? can't i just flash over radio.img with the one from mi 9t pro?
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] shadow78:
If you read back a bit you will find your answer, flashing an other rom would

not

unlock any band.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] Dorian.:
Also we don t have the global. Rom yet, am I wrong? It has not been posted anywere yet...
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] dev-DaT:
Not yet but it will come soon i suppose since it has been released in eu now.

[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] bagnolo2015:
guys it's useless to waste time, in fact nobody has ever managed to unlock the band 20 on Xiaomi devices!
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] Guido83:
I guess on this device it's a bit different as the exactly same device is released with B20 in Europe as well... We'll see
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] dev-DaT:
Did anyone do any diffs with the EU and CN radio image to see the difference?

Maybe we can reverse engineer some stuff?

This is gonna be interesting project.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] topaloglu321:
Any updates please?
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] :
Not sure what you people expect here.

Why should flash EU radio image should unlock something? If the K20 pro modem doesn't support B20 it will never change something if you flash another software.

Also my Golf GTI won't run on diesel when I flash GTD software on it lol.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] Robbo.5000:
The modem is the standard X24 that is baked into the SD855 SoC, which supports more or less all global LTE band. So the modem does support B20. It is therefore software that is controlling what bands are available. However I'm not aware of any phone where flashing a radio image from the same model, but a different region, has changed the available radio bands on that phone. So, while it is software controlling it and therefore could be changed in theory, it is very secure and very difficult to change.

So while you are right in wondering at people's expectations, your reasoning isn't quite right.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] :
There is also a x20 modem on snap 855. Maybe it's not the same?

Edit: I read myself a lil bit and it's the same... I thought they have different modems.

And for the others... That's what unlocking bands looks like: https://xdaforums.com/redmi-note/general/unlock-lte-bands-step-step-xiaomi-mi-t3084774/

It's just an example but I think you can imagine there's much more to do than flashing EU radio.img
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] Robbo.5000:
The X20 was on the SD845.

Yes it will require using Qualcomm tools to unlock bands, but whether we will ever get the software required for the SD855 is a different matter.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] :
Have a look at Qualcomm site. It says x20 is available on SD855?:confused:
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] Robbo.5000:
That's 100% a typo on the Qualcomm website. Look at the 8xx SoC page and you'll see the SD845 has the X20, then look at the modems page and you'll see none of the modems list the SD845. But it's well documented that the SD845 came with the X20 and the SD855 comes with the X24. Qualcomm don't make the same SoC with different modems, it's too expensive. Just loo at the 5G solution. The X50 is a separate modem that is an add on module, rather than manufacturing 2 versions of the SD855

[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] Kiki.G:
THEORY :

Do a NVRAM dump from GLOBAL version and restore it on CN version !??

That assumes cloned IMEI also but could prove CN version hardware have B20 capabilities ?

Opinions ?
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] lordkiller347:
On some devices it is possible to unlock bands. for example it has been done on the Redmi Note 7 Pro using DFS but unlike the Redmi Note 7 Pro the K20 Pro has a locked modem so it is not possible to make changes to the NVRAM

---------- Post added at 10:27 PM ---------- Previous post was at 10:25 PM ----------

it does have B20 capabilities but they are disabled and the modem is locked so it is not possible to unlock without a unique unlock code. and I doubt Xiaomi or Qualcomm would be willing to provide that
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] Kiki.G:
So, will dump and restore whole NVRAM enable bands !?
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] plskillme:
Not sure what to profit from that endeavor when the Mi 9T pro is already available.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] ma_ko:
actually yeah, I ordered Mi 9T Pro 8/256 some days ago (as I wanted this version of K20 Pro) , so i don't need to follow the thread but still it would be interesting to see how the situation develops

Why must this work? Have you read the thread fully?

The thread is about enabling carrier aggregation on Chinese phones, not about enabling extra bands.

It's also full of people saying it didn't work for them, with some having no mobile network connection after trying to restore the phone.

Probably best to give this a wide berth.

Hello,

I want to mount my SSD on the pre-created directory from the init.rc file. For an example, I have created the directory inside the /storage partition from init.rc file and my good news is I was able to create the directory named as 'abc' inside the /storage partition.

But my question is, How do I mount my SSD on that newly created directory(abc) in such a way that my application can access the SSD from 'abc' directory. And It should have all the permissions (read, write, execute) means I should be able to read/write without root or 'su'.

Just for your Information, I do have an Android 7.1.2 source code.

By the way, saying thanx in Advance.

Perhaps you should provide information as to what your carriers and your plans are.
[Nubia Red Magic 3 Questions & Answers] Jolly.B:
By default phone uses "Force close/stop" feature to prevent apps from running in background to save memory. As a result when you swipe remove the message/sms app or any other app from backround app list, they get forced shut down and you wont receive any message or they won't function any more. Follow this step to enable receiving sms or any other app:

Go to Settings > System > Advanced > 'DESELECT' Deep process clean

That's all :D

I stumbled upon this gem of a ROM. It's CAF based and has a ton of settings. It will certainly suit anyone's needs.

Here's a nice video showing all the features: https://www.youtube.com/watch?v=7TCj8c0E7Dc

Ingredients used:

1. Device tree: https://github.com/AOSiP-Devices/device_oneplus_enchilada

2. sdm845-common: https://github.com/AOSiP-Devices/device_oneplus_sdm845-common

3. kernel: https://github.com/AOSiP-Devices/kernel_oneplus_sdm845/tree/neutrino

4. Vendor blobs: https://github.com/AOSiP-Devices/vendor_oneplus_sdm845-common

ROM sources on github: https://github.com/derp-caf

Telegram: https://t.me/DerpCAF

Download link: https://androidfilehost.com/?fid=6006931924117934304

Installation as usual for OP6:

1. Flash ROM zip in TWRP

2. Flash TWRP zip

3. Reboot to TWRP

4. Flash opengapps + (optional) Magisk.

5. Boot to system

Tested on my own decrypted OP6.

Note:

Some people had trouble after flashing the rom, they report it took them back to TWRP. If you have this issue, try following this procedure (thx [MENTION=5284972]HatRiGt[/MENTION]) :

This ROM sounds promising because from what I have searched in google is CAF=good performance/less features and AOSP=more features/bad performance and now it is combined to one ROM that has good performance and more features as stated in the OP.
[OnePlus 6 ROMs, Kernels, Recoveries, & Other Devel] quake73:
I guess 9.0.5 is fine. No need for full format. Just do a backup first of your current rom (so that you can go back if you dont like this one) and then follow the usual steps as for any other rom, nothing special. Just the steps from my first post.

My twrp is 3.3.1.0.

Try immediately after flashing only Derp+twrp, boot to system.
