[Verizon Droid Charge] Chopstix9:
I've been running imnuts' debloated EE4 since last weekend. Rolled back to ED1/Flashed EE4/Edited build.prop ... After I flashed to the EE4 I had EE4 baseband but ED1 build still, hence editing build.prop

When I flased the EE4 the voice spoke occaisionally during first boot, which I assumed was the file structure being re-written. Phone has been working fine all week, no issues there.

This morning, out of curiosity, I tried to enter recovery mode, to see if it were voodoo or stock. vol.up/home/pwr and the samsung logo appears. But it doesn't enter into ANY recovery screen. It just stays at the Sammy logo until I pull the battery. What's up with that?

Also.... with file structure re-written, can this still be flashed back to say the stock rooted ed1 tar file still? Would there be any steps that need to be taken before attempting such?

Looking at voodoo log file lag fix is being enabled and such.
[Verizon Droid Charge] boostedjti:
Have you flashed the clockworkmod recovery odin file?

And before flashing anything not using voodoo just disable it.
[Verizon Droid Charge] Chopstix9:
How would I disable voodoo ?
[Verizon Droid Charge] boostedjti:
Just create a filed called disable-lagfix on your sdcard

Or disable it in clockworkmod
[Verizon Droid Charge] Chopstix9:
Just create a folder in the root directory named disable-lagfix and that does it? So far as cwm goes, that was one of the initial things I posted about. I've always been able to enter recovery mode by holding down up volume/home and power until the samsung logo appears. Then releasing them would bring the recovery screen up. Stock Samsung was blue lettering and then with cwm installed it was yellow with added options on the menu. Now if I try to get to that point, the recovery screen never comes up. It just stays at the Samsung logo and basically is frozen there until I pop out the battery. Phone boots fine into normal use.
[Verizon Droid Charge] boostedjti:
Recovery may just need to be reflashed.

But yea you can disable lagfix just to try it so you know how. If disable-lagfix doesn't work try using an underscore instead. Just be sure to reboot so the conversion actually happens

i think its something to do with NEXTG network support
[Galaxy S II Q&A, Help & Troubleshooting] caudex:
they all should support NEXTG.

Its just the SAR difference. the Samsung Website shows it when you look at the SAR values for the phone.

There are also the following variants:

GT-I9100 - 0.338 W/kg

GT-I9100G - 0.247 W/kg

GT-I9100M - 0.338 W/kg

GT-I9100T - 0.285 W/kg

This is what it says on the samsung site:

====================================

This phone meets European Union (EU) requirements concerning exposure to radio waves. Your mobile phone is a radio transmitter and receiver. It is designed and manufactured so as not to exceed the limits for exposure to radio-frequency (RF) energy, as recommended by the EU Council. These limits are part of comprehensive guidelines and establish permitted levels of RF energy for the general population. The guidelines were developed by independent scientific organizations through the periodic and thorough evaluation of scientific studies. The limits include a substantial safety margin designed to ensure the safety of all persons, regardless of age and health.

The exposure standard for mobile phones employs a unit of measurement known as SAR (Specific Absorption Rate). The SAR limit recommended by the EU Council is 2.0 W/kg.*

The highest SAR value for this model phone was <insert above SAR value>

SAR tests are conducted using standard operating positions with the phone transmitting at its highest certified power level in all tested frequency bands. Although the SAR is determined at the highest certified power level, the actual SAR level of the phone while operating can be well below the maximum value. This is because the phone is designed to operate at multiple power levels so as to use only the power required to reach the network. In general, the closer you are to a base station, the lower the power output of the phone.

Before a new model phone is available for sale to the public, compliance with the European R&TTE Directive must be shown. This directive includes as one of its essential requirements the protection of the health and safety of the user and any other person.

[Galaxy S II Q&A, Help & Troubleshooting] diamalus_BOFH:
Sorry to resurface an old thread, but I thought this might be useful to some people.

tl;dr I9100T phones seem to need I9100T modem firmware to ensure usable data speeds. They can be flashed with ordinary I9100 ROM and kernels, but reflash with I9100T modem firmware afterwards.

I think there is more of a difference between the I9100T and the standard I9100 than just the SARS value. Here is why I think so.

I have a I9100T purchased from Telstra in Australia - and I use it on the Optus network. When I received the phone it had modem firmware DVKF2 and kernel DVKF4.

The first thing I did after getting the phone was to flash it to Cognition v1.31 (XXKG3). After a few days I realised I was getting terrible 3G speeds – like 900ms pings and 30kbps up/down. So I flashed the modem to DUKF2 (I couldn’t find a DVKF2). Things seemed to perform much better but my phone seemed to jump from 3G to H intermittently and while speeds were fast, there was large “gaps” as it re-negotiated from 3G to H and vise versa.

So with the DUKF2 modem firmware in place I went searching for solutions and found the *#301279# code (which lets me control 3G, H and H+ modes). Just to repeat, I am using the Optus network, so there is no possibility of me reaching H+ speeds. My results are from the SpeedTest app. Here is what I found:

3G only: Speeds were only marginally better than flashing the modem with a non-I9100T firmware. 250ms pings 300kbps down / 200kbps up.

3G and H: The odd part is that in this mode the phone never jumped up to H. It stayed on 3G all the time. Weird. Anyway, I was getting 180ms pings and around 2 Mbps down / 300 kbps down. Now, things seemed to be more stable. After the initial ramp-up in speed, the chart would roughly resemble a table top as if I was hitting a speed limit.

3G, H and H+: This enabled the switching up to H mode. The speeds were the best here as I could get anywhere between 2-4 Mbps down and 300-500 kbps up. Pings around 100-200ms. The problem was the speed was “erratic” The charts were nowhere near as consistent as being in 3G and H mode (where only 3G was operating). This is because the phone seemed to negotiate between 3G and H and that would cause gaps. Sometimes it did this 2-3 times in the one test – and the test only goes for something like 10-15 seconds!

Just to make it clear, I tried all of these modes under a few different modem firmwares such as XXKF2/3 and XXKG3 that were made for the I9100 and I had terrible speeds regardless. It was not until I flashed I9100T modem firmwares did the speed improve.

What do you guys think? I have read that others in similar situations (Telstra phone I9100T on Voda or Optus networks having poor speeds). Or could it just be my phone and I should return it?
[Galaxy S II Q&A, Help & Troubleshooting] dansblackcat:
@ diamalus_BOFH

Have you tried the DUKF4 firmware?

I'm pretty sure DUKF2 is quite old.
[Galaxy S II Q&A, Help & Troubleshooting] diamalus_BOFH:
I presume you mean modem firmware? No. After some testing with DUKF2 I moved to JIKG1. I extracted it from an Israeli ROM. It seemed to be the latest I9100T ROM that I can find posted on one of the pages in this forum.

I achieved roughly similar results with both DUKF2 and JIKG1.

[Galaxy S II Q&A, Help & Troubleshooting] Jayman007:
I just bought this phone fin Thailand and they are selling 2 diff models of the Samsung Galaxy S2 here... The I9100 supports 3G 900/2100Mhz and the I9100T supports 3G 850/2100Mhz.

Now the question I have is do they both have the same hardware and it's only the firmware which has been set to either 850 or 900 Mhz? Here they are being marketed to different carriers. I wanted the 900Mhz version but realized when I got home that I have the T (850Mhz) version. My intention is to take it back and swap it for the non T one tomorrow.

After doing some searching I have read that some believe the phone hardware is the same and will support all bands for 3G but the firmware is different for the T and non T to limit what 3G freqs they can use.

I am looking for someone to confirm or deny this for me. Any insight would be greatly appreciated.

I'm also unsure if mine has NFC hardware in it. Is there an easy way to check this? I'm told that the thai market has disabled this feature but that makes me think the hardware is there and can be enabled with a diff firmware. How can I be certain?
[Galaxy S II Q&A, Help & Troubleshooting] Poulsen8r:
You are correct my friend. All SGS2's are the same hardware, they use a penta-band radio which covers all frequency bands worldwide (850,900,1800,1900,2100) and the modem.bin controls which bands are enabled and disabled for power saving and operator standards. No Galaxy S II's with NFC have been released yet as far as I know.
[Galaxy S II Q&A, Help & Troubleshooting] dc5dd:
@Poulsen8r

I've searched the net and there is conflicting info the the SGS2 using penta band 3G do you have a source for this info.

Also I played with my father in law's korean SGS2 and is has the NFC so it is out.
[Galaxy S II Q&A, Help & Troubleshooting] Poulsen8r:
Sorry I should be more specific the international Galaxy S II aka GT-i9100X is all the same hardware. However the SHW-M250X is a completely different animal. These are NFC enabled.

Can't remember where I got the exact information to be honest, it was a long time ago I heard this (last year some time). I can confirm with my device that it works as I stated before.

Have a look at these:

Thanks for the reply. I tried to access those sites but access was denied. What is the difference between the i9100 vs i9100M vs i9100T? I would really like to confirm that the i9100? has penta band 3G truly making it a world phone. Thanks
[Galaxy S II Q&A, Help & Troubleshooting] shnoz:
None of them are Penta band. They're QUAD band 2G and QUAD band 3G. You can;'t just mix the list of frequencies in with each other say Pentaband.

SGSII i9100(X) supports: 850/900/1800/1900 GSM 2G, and 850/900/1900/2100 WCDMA 3G.

A Pentaband phone would support 850/900/1700/1900/2100 WCDMA 3G - Like the Nokia N8 does.

The 1700 is only of concern to TMobile USA and WIND Canada customers anyway (I think one of the Japanese carriers includes 1700 support too - but its not mandatory). With the AT&T acquisition of TMobile USA they're going to stop using 1700 MHz 3G anyway.
[Galaxy S II Q&A, Help & Troubleshooting] shnoz:
The simple explanation of i9100 vs i9100T is that the T version is slightly tuned for better performance or preference for the 850 MHz WCDMA networks. Hence the difference in SAR as per the Samsung Australia website under specifications for this model.
[Galaxy S II Q&A, Help & Troubleshooting] Jayman007:
I have to agree with you. From all the info on the samsung sites it looks to be the only difference (SAR value). I own a T model and was told by the retailer that it would work on 850 for 3G but not 900 and low and behold I am using it on 900mHz (3G) just fine. A bunch of marketing hype here in Thailand to keep you from switching carriers thinking your phone won't work on the competition but it very much does without any modification.

[Galaxy S II Q&A, Help & Troubleshooting] ewok666:
This is for Optus (or other 900/2100) I assume? Both the original Telstra and Vodafone modems are available somewhere on XDA. I'm on Telstra and have not had real issues with any modem. You could try to do a factory reset to clear old settings after you flash one of the 9100t specific modems. I noticed that at least some of the modem specific setting are not cleared when flashing a new modem but they are after a factory reset.

I wish Samsung stopped making 10 different versions of the same phone.....I wasn't planning to buy a 9100t and just didn't know that there were different versions in Australia and that Vodafone was a 9100t.....

[Galaxy S II Q&A, Help & Troubleshooting] codebeard:
I am trying to use a Telstra i9100T on the Optus network -- I am really annoyed that it doesn't work with other modem firmware and I am afraid to flash anything to it.

I bought my phone second-hand from someone who didn't mention that it was a different model phone, so I assumed I wouldn't have any problems using it with Optus.

I'd really like Samsung or Telstra to release information about what makes the i9100T different, and provide proper working firmware for non-Telstra networks. I mean, I paid a lot of money to get a quad-band phone and had no reason to expect these problems. Do Telstra or Samsung have any legal obligation to their customers in relation to this?

I felt like this.

But the reality is that the DVKF2 and the DUKF4 modems work fine.

You can flash any ROM you want, if the ROM comes with a modem, just remember to flash DVKF2 or DUKF4 over the top.

---------- Post added at 11:46 PM ---------- Previous post was at 11:41 PM ----------

I think this is why there has been some inconsistency in the testing of modems.

You need to flash the modem, restart the phone and factory reset. Then 2 restarts, just for good measure??

So you have KI4 working fine on a i9100T??? This is a fairly big deal, many other people have not been able too? And it is possibly just because they have not factory reset the phone? Or do you have a early mode i9100T that is the same as the i9100...
[Galaxy S II Q&A, Help & Troubleshooting] codebeard:
Thanks for your reassurance. Are you also using a Telstra I9100T on Optus?
[Galaxy S II Q&A, Help & Troubleshooting] furyau:

I put KI4 modem on yesterday and this time, full reset the phone, reinstalled the ROM, tested everything, multiple restarts etc.

KI4 and other international modems just do not work very well at all the with i9100T.

There is a difference in the hardware.
