Default Latest modems

On my old S2 I had great success in improving signal with trying different modems, especially with data.

Since getting my S4 I've noticed that data signal is not so strong as it was with my S2.

DJembey has a thread on XDA with modems flash able through Odin, see here http://forum.xda-developers.com/showthread.php?t=2192025

Anyone tried and had much success with any of these? Obviously any success is greatly influenced by carrier and area, but any feedback would be great.

Although we are on the same carrier Syd, albeit in different parts of the country, the first thing I noticed on the S4, across all firmwares I have used, is how much better my signal is. At my desk at home, I used to average -85dBm and 11asu and now I am getting -75dBm 19asu. The lower the -dBm and the higher the asu, the better.

Even at the one place that is known locally for its almost total lack of virtually any signal, a pub, referred to as the Twilight Zone, where I tend to carry out a lot of modem testing, I have actually managed to get a 3G signal, now and then, and not just EDGE.

Anyone wanting to check their signal, should go to... Settings > More > About device > Status > Signal strength.

On a separate note, on my SGS2 I used to pick up about 11 satellites on my phones GPS. On the S4, it is around 23 and a fix is under 10 sec's with an error of around 10ft, (3.05m). Very impressive!

So it looks like Syd volunteered himself as the go to guy for modems. I'm going to enjoy this

Anyway does anyone know where I can get the mga modem? I've tried the one from the link above and mobile Odin tells me the file doesn't contain the correct partition. I've tried flashing it as a .tar and .tar.md5

MD8 MODEM

After rudedawg's recommendation have flashed this modem.

For me, in uk on Vodafone, in a poor reception area, it has so far given me the best signal strength of all modems.

Thanks rudedawg.

Woo hoo it wasn't just my imagination. But as its Syd I'll hang on before celebrating


As a EE customer my signal stepped up to 4G more often than before. This was tested in areas I know to usually give me drop outs or single bar 3g cons.

I tried the i9505DVUAMD8 modem for a few days and for me it made no difference whatsoever on Vodafone in my location. If anything, it was slightly below the MGA modem I have been using for the last few weeks.

This just goes to show that different modems behave differently for devices depending on carrier and location and that there is no such thing as, "the best", modem.

I believe that the i9505DVUAMD8 modem is from the Australian Vodafone firmware which, IIRC, operates on a different band from European phones, 1800MHz for 3G, and in my SGS2 days this was a, "T", modem!

Does that mean in theory it shouldn't work so well? Coz in practice now getting stronger signal at home than before.....how odd?

And thanks for the heads up on 3minit...

Don't quote me on this... but the 2G and 4G networks are the same. It is only the 3G band on Vodafone Australia that used to be different. Hence the T modems. However, I do not know enough about the S4's Australian, Vodafone, modems to say whether this would still be the case. As I mentioned, for me, the MD8 was about the same'ish as all the other S4, JB, modems I've tried. All have been pretty darned good. Unlike the S2 modems that did register a big difference in some cases.

Miffed at the problems encountered with the DjeMBeY release of MGG I went ahead and installed the XXUDMGG modem, for the i9505, from here, using Odin.

Early days yet, I've only had it on for around 18 hours, but so far in the locations that I have used it, the performance has been very good and possibly better than MGA/MH1. Rigorous testing will continue but well worth a try.

MH1 is very good, for me. If MGG is any better for Ironass I'll flash it. This given I too am on Vodafone.

These modem files are huge (50Mb+) compared to the S2 modems (8Mb+)

I've never flashed a modem through Odin before. I assume the .md5 file must be loaded into the PDA section?

Be warned however....Its a slight worry flashing modems on the S4, as a CWM flash is not possible (as yet). This means if things go wrong, the only way back is an Odin flash of the original ROM as modems, of course, do not get backed up in a CWM backup.

No, load it in the phone section in Odin.

I suppose that's why it's best to let the idiots test it first Hawker!

No, no, you do yourself and ferrite posterior down Syd. Someone has to try these things.

No one has mentioned RILs yet? Are they still as important? 'Get RIL' doesn't work yet :

If you go to advanced backup and restore, custom backup job in Philz recovery you can backup the modem. I haven't tried this feature though so I can't say how reliable it is.

On another note has anyone managed to flash a modem with mobile Odin? They always fail for me.

I tried and failed, although I noticed on xda recently that you have to rename the.tar.md5 file to just.tar, which I've never done, so might try that.

I've tried renaming the file before and it still doesn't work. It'll either fail or won't even let me attempt to flash because of the wrong partition or something like that.

I can tell you now dynomot... modem testing is a serious and meticulous business. It's not all beer and skittles. For a start, they don't have a skittle alley at the Twilight Zone. Partially overheard conversation between a friend of mine and a friend of her's, at the TW pub... "... we only come here so that he can get it out and play with it!"

That's worth knowing, Shotty!

Same here. Always use PC Odin for modem flashing.

Can't answer that one sntaylor. It must be over 2 years since I used stock recovery... can't blinking well see it on the S4, anyway!

If you're lucky, yes butty, but there have been reports where S4 modem flashes has been fubarring efs+IMEI information, and curiously in some cases, breaking the sound on the GS4, so you may have more work than you bargained for.

I'll wait until a bootloader-fiddled release of MH8 emerges.

In all seriousness, I really don't know why I stick with Vodafone (all right I do, I screw them every upgrade time or threaten to leave) in towns and city centres it's fine. Suburbs generally fine. Anywhere where you can see sheep (Hawker would be FUBARED) nada, or very poor GSM signal.

Point taken. In that case, as you say, an original ROM flash is the way out.

Biting the bullet, I'm trying the MH8 modem now
The ordinary flash didn't work for me neither
The instructions at the OP of the modem thread did work for me however. Ie:

Use Odin v3.04
Untick Autoreboot
Flash modem
Reboot once again into Download Mode using (Vol Down plus Home button combi)
Flash Modem once more
Once done,unplug then reboot device manually.

Been on the MH8 modem for a couple of days now. Haven't noticed any difference from the MGG modem which was very good for me.

Touch wood, no problems flashing with Odin PC.

I wonder if the trick is perhaps not by following those steps line-by-line, but just by entering download mode manually, as opposed to using the power menu.

How are you getting into download mode butty?

This may well be the reason then.
Shotty, were you getting into download mode via the power menu?

Ive had constant issues with getting into recovery since rooting this phone. All in relation to the manual way (holding buttons). Always had to go in via rom manager or power menu.


Luckily download mode is 100% succesful 100% of the time.

I can confirm going into download mode through the power menu as opposed to manually going into download mode with the three-fingered knuckle shuffle affects the ability to flash the modem.

I was getting problems on MH8 modem, with it taking a long time on boot to get a signal, and also it seemed to be affecting my GPS lock speed (which is odd as GPS is kernel-related as far as I know) Anyway, I went into download mode using the traditional method, reflashed MGA modem, and it worked first time.

So, don't use the power menu to go into recovery mode for a modem flash it seems.

Just flashed the latest modem, MI1, which has been taken from the XXUDMI1 firmware for Vodafone Germany and Spain.

Early results, as with all the S4 modems I have flashed to-date, are good but no different to previous releases for me, at my desk. Will test extensively over the next few days.

The MI1 modem can be downloaded, here, for the GT-i9505 and needs to be flashed via Odin. Note... the file reads XXUDMHI1 but is in fact XXUDMI1.

I'll get right onto that then Syd, shall I?

Perhaps I could stick a broom handle up where the sun don't shine and that way I could sweep the floor as well!



UPDATE

At my desk, there is no discernible difference between MHB and MI1.

Is it worth experimenting with different modems?

The only shortcoming of my S4 is the apparently poor reception compared to my S2. I changed carrier at the same time so it's hard to compare but I am now on 3 (from O2) and I used to use a 3 MiFi dongle and it had far better reception than my S4 does.

Syd... whip round and have a strong word with your fellow Yorkshireman will you and explain to lotus49 about the arduous and dedicated testing of modems that I have carried out at the Twilight Zone pub!

To be serious, for a change, unlike the S2 modems that did fluctuate between releases, the S4 modems have been virtually identical and consistent after the initial early releases.

Quote:

For me, the S4 offers a significant improvement over the S2 for signal strength in my location and with my carrier. However, I cannot comment on the 4G capabilities as the nearest coverage for Vodafone is London or Birmingham for me at the moment and is unlikely to materialise in my area for another year.

I tried MHB and MI1 and as mentioned above, there was really no difference for me in a variety of locations. However, for some strange reason, I found a bigger battery drain when using MI1 as opposed to other modems I have tried! I have re-downloaded and re-installed it again to see if BBS will give me a reason for this... maybe a higher FD or something similar.

One of the pains is that unlike the S2 which had flashable .zip files, the S4, i9505, modems need to be flashed via Odin PC suite, (Mobile Odin doesn't seem to work for me on modems), and so I need to keep returning to the Twilight Zone.

Just a small word of warning.
Flashing modems on the S4 isn't quite as innocent compared with the good old days of the S2 where we would hurl our cac-covered flashing boots at it and still come up smelling of roses.

As yet, modems cannot be flashed via CWM, only Odin. To me, this poses the question "why not?", so you should be cautious from the offset. Even then, odin only flashes a modem properly if the device is put into download mode through a power-down and not through the power menu. Again, alarm bells ring at me.

Personally speaking, I would not recommend flashing modems on the S4. On the S4, modems seems to be more tightly linked to the firmware version for which it is intended. Flashing alternatives is not without risk and can lead to serious problems like wifi and sound disappearing. Getting these back to a working state has been a very long winded and laborious task for quite a few unfortunate people, with cwm restores and even reflashes of stock firmware not being sufficient to return to the status quo.

Of course, if you have nads the size boulders, akin to ironass' then this will not represent a problem to you, but to the mere mortals amongst us, its not something that is to be taken on lightly.

I really don't think its worth the risk considering the minimal (if any) "benefits".

@ lotus, i have flashed every eu modem that is possible to flash with 0 repercussions

Hawkers words whilst wise are also very cautious

flashing a 500 phone in the first place takes some bottle.

take my words for what they are, youve already pushed the warranty boat out of the harbour

Wise words from the old Soggy Moggy!

The only way that I am able to flash modems is via Odin and by booting into Download Mode, manually, 2 fingered salute of Volume Down and Power. I have flashed modems up to and including MI1 with no issues thus far. See disclaimer in next paragraph.

Two things should be borne in mind...

1. Hawker has been peeking in the showers!

2. That I am still on a pre locked bootloader and Knox Security firmware, MH1, and I believe that the problems that the old boy is warning us about, occurs when you are on a post MGG firmware and attempt to mess about with flashing older firmwares and or modems on the locked devices.

Quote:

I have to agree with this as I have found that all the modems I have tried since the very early MEA releases, have all been virtually identical for me and no one modem has been appreciably better than another so far.

However, having said that, this will not deter me from testing future releases at my usual proving ground... strictly in the interests of science you understand!
