the app store bills through the itunes account doesn't it? I guess the purchase blocking for the phone bill is to prevent freud. I've used andriod since before I knew that was an option and pay for apps with my debit card, though I may put it on my phone bill now because I hate to see my bill change and it'll keep me from making impulive buys, the few dolars seems more significant on my phone bill than out of my bank account. I have like 10 apps that are useless to me now and will never use like rom manager and set cpu.
[HTC Sensation] ajay83:
Hi guys.

Currently have a dhd but o2 have offered me an early upgrade.

So I'm getting a Sensation next week. In the past they've sent me unbranded handsets & some branded.

Just wondered that once the s-off method has been made public, would one still be able to Debrand & use custom roms as I have been on dhd?

My apologies for the lack of knowledge. Just that I've not had to make goldcards etc on dhd as that came unbranded from o2.

I'm sure someone will make a guide etc.. Xda is very helpful like that

Thanks Y'all

AJ.

After S-OFF you can flash any rom you like, so you can definately debrand your phone.
[HTC Sensation] bruce2728:
The only branding on my o2 sensation was the wallpaper, I haven't checked the simlock yet but I assume its locked to o2
[HTC Sensation] deathdark:
Normally at germany HTC sim lock isnt allowed. I believe its the same for Eu devices
[HTC Sensation] ajay83:
Hi guys what I mean is o2 & other networks have a different software number to the official htc one.

So even if I do have an o2 branded handset, once the s-off method is here can I just proceed with goldcard, then downgrade & straight into a LeeDrOiD rom?

I was lucky with my dhd from o2 as this one kept the original htc software version & not o2's own.

Thank you for the advice & help guys =)

I was so happy when phones4u gave me an unbranded one! Orange generally put loads of ****e on the phones!
[HTC Sensation] Sdobron:
We don't know the process yet. Downgrade was specific to dhd for an exploit for radio s off.

Simply put though, once you have s off you can flash any rom.

First off i need to thank Xda user KevL for putting me on the first step in the right direction to getting here! Thanks!!!

For any one using and running i897 modem for the love of audience chip support on their device and also need band selection to lock 850 band, this thread is for you!!!

I first started using i9000 modem kernal combos just for the band selection ability.

After AdamHolden85 Allowed me to continue development on his KB1 Fusion rom i started a mission to unlock the "Rat". I gathered much information from users that suffered from "Rat". (weird that some users with i897 modems installed don't have this restriction, but most do)

Some may ask "What is "Rat"?"

dial *#2263# on your captivate while running a i897 modem and you get:

but what you are after is:

So lets get to it shall we!

This is really more of a security loop hole!!

1=Remove the simcard from your phone with out removing battery!

(use your nail to lift the edge of the card over the battery lip)

2=dial *#2263# and you will first get "RAT", wait for this pop up!

3=hit "OK" and dial *#2263#, and now you are in!!

4=select the bands you wish to use

5=Menu hard key to get popup here and select end!

6=place device into airplane mode!!

7=reinsert your sim with out removing battery!!

8=Turn off airplane mode and watch cell bars grow and data to connect in your status bar.

9=Dail in *#0011# and check for your self!!

May work on other band selection RAT modems, I only can confirm JH7,JH6,JI6,KB1,and KF1!

FAQ, at OP's request

FAQ

​

1.

and in response

This does not effect data speeds because this has nothing to do with HSDPA/HSUPA/HSPA+. That is dependent on something written within the modem that XDA is yet to learn about. (no one seems to wanna touch the modems, in part because they are heavy with proprietary code for things like the bluetooth chip and the GPS chip. proprietary = closed source and a PITA to mod) Tho using GSM = 2G and WCDMA = 3G, so be careful about which 850 or 1900 band you are choosing.

2.

This does not allow for mismatch with kernels, as that is HW communication dependent. Your kernel talking in a 1234 pattern and your modem talking in a 4321 has NOTHING to do with RAT or the band/frequency that your phone it trying to speak to the antenna with.

3.

This does not remove RAT, it gives us a means to work around it. At this point we still don't even know what triggers RAT as some I897 users have shown to not have such restrictions. Until we have figured that out we can't kill RAT, tho we do know it is something within the I897 aka AT&T modems.

4.

and in response

Settings may get dropped on reboot, sry but for now this is only a change held in the RAM.

Other things to note:​

Phone stays on and running the whole time. The most time consuming part of this is waiting for the phone to realize the removal/insertion of the sim card.

-SGS Tools / nitrality- apps have the "secret/service codes" to speeds up and or ease the process.

No love for WCDMA 900... even on fully auto that lone band is unused.

Folks, follow the instructions exact, and take your time. I tried toying around and skipping = not successful.

Lastly you can't seem to force it to run an unsupported band (like I did with the WCDMA 900), it will eventually seek its way into service again. Keep in mind that having

RAT means

we have

limited control

over this aspect of the phone.

Also, LOL that I can force it to use GSM and only have edge data :D

[Captivate Android Development] xpakage:
Does this mean UL/DL speeds can be improved on those listed modems?
[Captivate Android Development] Johnsondr80:
Not there yet. But they say 850 is faster due to less users clogging the line.

Also the 850 Band travels better so you'll see stronger signal more often. Should also give better call quality, tho I'm not 100% on that part.
[Captivate Android Development] thumper_1151:
I just wated to verify.....So there will still be no hspa with the i897 modems... And the same bugs with using a I9000 kernal aply, no buetooth, is that corect? This just alows band selection?
[Captivate Android Development] DaNaRkI:
Yep, I897 modem is still hsdpa only. Yep, does not add any new kernel compatibility. Yep, does allow for band selection (tho still not a easily as those without RAT)

So, it is mainly useful for devs / testers, and ppl who have dumb phones that love using 1900 band during heavy traffic and/or low signal.
[Captivate Android Development] Johnsondr80:
No, you are right.

It dose travel better and reach futher, with stronger.signal.

I have tried this a couple times and it doesn't seem to work for me. RAT is still restricted at the main menu.
[Captivate Android Development] DaNaRkI:
This does not remove RAT. As Johnsondr sneaks in there "This is really more of a security loop hole!!" In that you can enter the menu with the sim card out and lock in the phone to use your band of choice. When you put the sim back in it stays locked in.

Annoying yes, but at least we now have a means of changing the band when service is generally crappy.
[Captivate Android Development] phoenix2217:
I notice if I reboot my phone it sets back to 1900 again. I made sure to follow the steps correctly three times. Is this how it works?

Cognition V1.0 KF1
[Captivate Android Development] Johnsondr80:
Most times it will stick past reboot.

Unless you visit recovery for some reason and then reboot from there.

Try a airplane toggle

I find that if I get back on 1900 for some reason. Airplane mode for a second and it goes back to 850.

Like Dan said earlier. This is not something we are supposed to have access to and are limited to the full effect of it.

I'm confused why do you think I posted in the wrong thread. I did your step to get audience chip support. Audience chip is suppose to offer better voice quality. Am I missing something?
[Captivate Android Development] jack man:
did this a couple more times to make sure I went through the steps correctly and both times when going back to the menu to see what band it was on I watched it go from 850 back to 1900. This was without a reboot or any button pushes. I hope we can find something that will work consistantly.
[Captivate Android Development] golfslicer:
This works, however, it does not stick on reboot.
[Captivate Android Development] insaneturbo13:
My guess is that your on an I9000 rom and flashed a captivate modem. In which case audio quality will be ummm pretty much gone
[Captivate Android Development] DaNaRkI:
Maybe you miss read. There is nothing here to give audience chip support to those who don't already have it. OP mentions this is for ppl who choose an I897 modem+kernel so that they can use the Audience chip.
[Captivate Android Development] Johnsondr80:
Maybe the op makes the intent a little clearer.

Thanks for the tip.

And this dose not change the rules to modem kernal matching rules.

It only allows band selection menu to be reached by those suffering from RAT.

What exactly is this RAT thing and what is it supposed to do? I'm on Mosaic with a i9000 modem and I don't seem to have any problems whatsoever.
[Captivate Android Development] Johnsondr80:
Radio Access terminal.

and what it does is keep us at&t i897 users locked down to the bands at&t has chosen for us.

Well if you ever make the jump to a i897 modem and kernal combo for better call quality you will need this. Until then you are right.

You do not have rat on a i9000 modem...and also no audience chip support. :(

i896 doesn't have audience chip AFAIK so.... meh w/e!

Aren't modems supposed to lock you down to either 850/1900? Since that's what AT&T uses?
[Captivate Android Development] DaNaRkI:
They do, between those two, but not to any specific one. The problem comes in when the phone seems to have a love for picking one band and staying with it all the way down to one bar or less, even tho the other might have three or more. This is really annoying in areas where one band is always low and one is great, yet the phone goes after the former resulting in bad service.

[Captivate Android Development] Johnsondr80:
See this is the situation I am in. At my home 1900 band holds 3bars or less. In some places at my house it will get as low as 1 bar. Making phones calles irritating. Even tho 850 band is full bars it continues to hold 1900 as the preferred band.

Now I can use this method to lock the 850 band and enjoy full service all over my house. :D

att modem+kernal

Doesn't the combinaton need to include all Three, not just the two(ATTbaseRom+ATTmodem+i897Kernel)? I know i read a few posts back that if using i9000Rom in this equation the call quality is terrible. So, other than Any ATT based(KH3,KI2,KJ1) rom, are there any other roms that could be used with the ATTmodem+I897kernel combination...like say a rom made for another ATT phone?
[Captivate Android Development] DaNaRkI:
I believe it's not so much the ROM, as it is the dialer and maybe a sub-component.

The issue (as with I9000) is either the audience chip is a different type or simply nonexistent.

[Captivate Android Development] RashaMatt:
This trick does get me into the RAT menus and let me select 850-only. But the selection seems to revert back to all-bands after some (minutes or hours), making it ineffective.

Anyone else have this issue?

[Captivate Android Development] Johnsondr80:
For my device it will hold till I reboot or fall from a area that has 850....say like I drive out of the area and into a edge network.

well, this trick worked for me, but i used the same trick to try and set it back to automatic, but now my band will not return to 1900. it is still on 850, even after a reboot. haha, seems to be the opposite problem than everyone else has.
[Captivate Android Development] IceMonkey82:
I'm curious about something ... It was mentioned that some people don't have this restriction but most do. I'm one of those people that doesn't have this restriction. For those that have the restriction, has the phone been unlocked from AT&T? I ask because I can think of two things that could be different: 1: my phone has been unlocked so I can use it with any carrier and 2: I'm currently using it with a different carrier.
[Captivate Android Development] TRusselo:
im on KJ3 build on a rogers captivate (original carrier but unlocked), No rat restriction.but 1900 has always tested faster for me in my area anyway.

just a thought but could it be something written on the sim card that is restricting rat, since you must remove sim to get around issue..... and the whole restricting to a certain frequency has CARRIER written all over it. and flashing custom roms with no CSC info, you should be clear of any carrier settings normally found in stock roms. its either something outside the system folder in the root, or the SIM card.
[Captivate Android Development] rajendra82:
It's not the SIM card, because on my Captivate, I am freely able to do band selection, if on an i9000 ROM. When I switch back to a native ROM, the option to select the band goes away with the same SIM card in place. I believe it is a behavior hard coded in the modem.bin, similar to the HSUPA blocking.
[Captivate Android Development] IceMonkey82:
It could be hard-coded, but I think that would further strengthen my point. I don't have the restriction whether I'm running i9000 or native. It could be that the AT&T modems check to see if the phone is still locked to the original carrier (AT&T) and restricts access so the carrier has control over this function.

On a modem that's supposed to work on any carrier, it wouldn't make sense to lock it out, but if it's only supposed to be one carrier, it makes sense (as far as the carrier is concerned) to lock it out.

It's just a thought and since one of the first things I did when I got my phone was unlock it so I could use it on a different carrier, I have no way of testing this theory.
[Captivate Android Development] DaNaRkI:
We'll look into it, but is there a way to re-lock the phone? Else we won't be able to do retests. Also not everyone who is carrier locked has RAT. So even if being unlocked helps free up phones, it is not the reason.

Also, things that have been tried by others includes changing the SIM from a nonRAT phone into a RAT one. So it was ruled out by someone before we found this.

Two things to note:

I (since I can't speak for others on this one) have not heard of a single case of someone getting free of RAT. The phone from factory comes restricted or free, there has been no consistency in it that the community has been able to find (maybe someone at Samsung or AT&T knows).

As some displeased ppl have posted, this work around is unstable and unreliable. The way I understand stand it to work is: no SIM = phone has no info about the network, so we can do whatever we please to the settings. Once the SIM is in and the phone is talking to the network, phone settings = null and void, but will stick untill the network tells the phone it

needs

to change (else lose all service).

In the case of I9000 ROMs there is some lack in the networks authority to control the phone, so the changes in settings are never overwritten.

We are guessing that whatever allows for RAT is in the modem mainly because no one has poked around and come back to talk about it. Just like how we would all love HSUPA but it is of a similar nature, network overrides any phone settings on native firmware.

also a temp fix which I believe lost after switch to airplane mode

but seems to actually stay until reboot or airpmode...dial

*#*#4636#*#*

then select phone info...

find the selector fot antenna

push "turn off" wait a few seconds then	"turn on" and immediatly check "gsm only"

if you do it fast enough it will stay

its a lot of fingertapping but I dont use flight mode often and wcdma1900 is almost nill where I live so it makes a huge diference 4or5 bars instead of 0or1 bars

MAJOR DIFFERENCE!

i know its not something to complain about, as most people want this to be the result, but the 850 band does not seem to work as well in my area, but i cant get my phone to go back to the 1900 band. I can use this threads method to set it to only connect to 1900, and that works until i reboot, at which time it goes back to automatic and is back on 850 band. any suggestions?

[Captivate Android Development] DaNaRkI:
nope. this is a "work around" that does little more then pit the OS against the modem. No mod/tweak/flash means we are working within the rules of the system. Those rules for (some) AT&T modems say "phone controls confection", best we can manage is getting the setting to stick for as long as service is available. Since a reboot means a complete loss of service the phone then changes the settings till service is back.
