0010160 Baseband version 9x15A-ACEFWMAZQ-30110098-75I post a ftf file can change band config to yuga_gltewtr_L1357_20W1358(the c6603 default band config), but also need replace rfnv by you self
I noticed all default rfnv files are read from ta partition, is there any way to delete ta value? so that we can fully switch band by flashtool

did someone check that whether 4g is working or not?
Hi
To erase a unit, you have a write a 0 length value to that unit.
That's what I do to erase bootloader unlock code from TA (https://github.com/Androxyde/Flashtool/blob/master/src/gui/BLUWizard.java line 181)
Found my LTE signal of telecom ,But can not register(login?)

Hello all, I got in touch with @SquallATF, sent him my TA, got from him custom baseband that I flashed and success!
I can see two LTE networks in Croatia, bands are 3 and 20. I will get LTE sim card and try to connect, will post here if success.
Thank you @SquallATF!

You will success,because many people flash SquallATF's baseband and got LTE already.
But it seems only Band 8 in Taiwan.(looks no band 3 in Taiwan)
Actually,Its a little different with C6602&03 chip ,So..may some bands can not support.
SquallATF guess support 1、5、8 only,its need more testing to prove.
In China & Taiwan, Our main band is 3!

It's sad to know there's no "Free upgrade to a 4G phone" for L36h but still big thanks to @SquallATF ! Amazing work.
EDIT: band 3 works for me, and band 5 maybe too (because another carrier uses band 5 here, and when my carrier has no signal coverage it will fallback to their network and provide emergency call service)
Anyway the only thing to find these days is that our carrier's 4G coverage still has a long way to go...

Is there a chance to port this method to other sony devices? Would you be so kind to post a full manual step by step, including software you use!
Tnx!
Tnx!
Could you indicate how you write m9kefs1 m9kefs2 m9kefs3 partition dump from c6603?
Thanks for your indication but "dd" stands for what?
in post "98 you have added a zip file containing rfnv files.
Could you explain how you have replaced orignal rfnv with the one you provided?
Have you succeed to change TA partition? Should it be the case how have you done it?
Thanks in advance for your assistance and great job.
Sorry I can't help you, because my main hard disk broken and all data lost.Thanks for your indication but "dd" stands for what?

My friend send me the c6603 n9kefs1-3 dump, and I use dd write theme to my phone, but this is not the best way and have some problem.
You can see my post, I build a ftf can change baseband config
If you want flash to 5.0 device, you should replace amss_fs_1.sin, amss_fs_2.sin and amss_fs_3.sin from 5.0 firmware.
Can you please guide me step by step?Do i have to only flash @squallatf baseband?what for 10.7.a.0.222?

Hi,
I have z c 6602.
Because of resolving a problem about internal speaker of phone, a mobile fitter opened it and changed the speaker, but there was no software reapir.
And
Then, When i was searching for service provider, i checked the preferred network type, and i saw LTE.
I selected it, it's now active!!!
