Hi fellas,
I was wondering if enabling all WCDMA bands 850, 900, 1900, and 2100 of our i9000 phones would produce any bad effects or would deteriorate our phones or its parts?
I tried to enabled them in *#2263# and they seem to be persistent so i believe they are active. It was initially set as 900/1900/2100.
Looking forward for replies
if you bought i9000T it's supposed to work with 850 what the others can't, that's from what I know..
I'm just not sure if it is really functioning or how to verify if the phone is really using the 850 or 900 wcdma band, or both (together with 2100 and 1900). AFAIK, wcdma's requirement is that at least 2100 is enabled, paired with another supporting band either 1900, 900, or 850. (tho just 2100 solo will also work but not as best if without another band to use)
I'm also wondering, if the original i9000 can support quad GSM and quad WCDMA, why is it that it is only set as tri-WCDMA only?
I guess my only concern is that if the phone's antenna system will be damaged if i enable quad band WCDMA (if it is really using it)
Folks,
If you have checked with the Service manual and Schematics, some variants of Samsung Galaxy S lack the required PAM for the UMTS Band VIII (900) operation physically, while some lack the required PAM for the UMTS Band V (850) operation. Sure, we can flash it with the corresponding modem.bin, toggle "WCDMA 900 (FDD VIII)" and/or "WCDMA 850 (FDD V)" with our targeted Galaxy S variants in the Band Selection menu but it does not mean they will actually work in the "Quad-band WCDMA" as we would like.
Try to hook one up with a set of signal isolation box, signal generator and analyzer (R&S, Agilent, etc.), then you will find out our Galaxy S is capable of "Quad-band WCDMA" or not for sure. DO NOT get confused with the "Quad-band GSM"... "If it can do quad-band in 2G, then why not in 3G?" BECAUSE the it is handled by another set of PAM and FEM.
Nevertheless, most of us are doing fine in the EURO/RoW regions where most 3G networks are deployed in the UMTS Band I (2100). Unless we are heading to the rural or specific areas where only has got the 3G service in the UMTS Band VIII (900) only (AND we apparently must use the 3G service at the same time).
thanks howipig, very nice answer

Project1.exe,
No problem but I wish someone out there can make our dream come true by adding the right PAM and SAW filters for the "extra" 3G band support
i'm thinking if it would be possible to extract files from, say, a Rogers (Canada) SGS for the 850, and combine them with euro for 900. I'm actually using XWJV1 (leaked gingerbread) and I got excited cause I see both options.
Project1.exe,
Like I have mentioned before, the software is just part of the puzzle. We can toggle all 3G bands showing in the Band Selection menu. In fact, I have played with a modified Galaxy Tab that even has UMTS Band IV (AWS) selected too! But in reality, it never works on the AWS band. The PHYSICAL hardware is the key. Without the right components, we are not going to make it happen.

In Europe, 510 is listed as RM-914 on Turkcell.
I have no idea, nor can find the RM# for AT&T version of 510. Does anyone know?
I did some digging on my own trying to figure out:
According to Phone Arena,
GSM 850 / 900 / 1800 / 1900 - all versions
I believe this means both 914 and all other versions use the exact same voice radio, and would work anywhere in the world.
Turkcell and Vodafone uses GSM 900, and Avea uses 1800. Good with all 3.
AT&T uses GSM 850 and 1900
HSDPA 900 / 2100 - RM-914
HSDPA 850 / 1900 / 2100 - RM-915 (I believe this is AT&T version since AT&T uses 850/1900 for 3G)
HSDPA 850 / 1700 / 1900 / 2100 - RM-917 (I believe this is the one sold by T-Mobile)

I took the plunged and ordered 2 Lumia 520's.
The only problem I see is that AT&T has put a restriction on SIM unlocking, I can't find anyone who will unlock this phone for cheap, and reports indicate most of them are refunding and claiming they are unable to unlock it.
AT&T Lumia 520 is RM-915

520? Which one?
Either one, both should work for me since they both seem to have similar networks, I just need one that can work on same data networks as RM-914. I will be sending this over to be used on Turkcell.
Hey, my girlfriend bought a g800F off of amazon, and the 4g doesn't work, we've tried working with her network and I think it's her phone. She can take calls, use wifi, etc. but only ever gets 3G service. Is there anything I can do to remedy it before she has to send it back?
Perhaps the device doesn't support the band your carrier is using for LTE?
The S5 mini should support the following bands(from a quick internet search, so might be more)
Code:
800 (band 20), 850 (band 5), 900 (band 8), 1800 (band 3), 2100 (band 1), 2600 (band 7) MHz/Duplex FDD
Find your carrier in the link below to determine the bands they use:
https://en.wikipedia.org/wiki/List_of_LTE_networks
If the carrier is supported then you might want to try a ROM reflash from SamMobile, and if that doesn't work then the device may be genuinely broken and should be sent in. Carriers can also selectively enable LTE and some charge a fee(so it's not on by default), but I assume you already did that as you said you've contacted the network already.
Shoot, it looks like her carrier uses band 4. Where do I find a list of bands for the phone?

I have a question for all the lucky ones of you who have a Mi Mix.
With most of the Xiaomi phones which are released, people are unhappy about the lack of band support for regions outside of China. I know many people in Europe are unhappy about not having Band 20, those of us in Japan would really like to have UMTS Band 6/19 (among others), Australians want LTE Band 28, and people in the US would like Band 12/17.
As you may know, with some phones, it's possible to unlock these bands by putting the phone into diag mode and using Qualcomm tools like QPST. Here in Japan, it was possible to enable the UMTS Bands 6 and 19 on the Mi5 and the Mi Max, but not possible on the Redmi Note 3 or the Mi5S, so it's really case by case.
Seeing as that the Mi Mix is a concept phone people are crazy about all over the world, I am very curious whether it's possible to enable LTE bands and WCMDA bands on the Mi Mix. I don't want to spend the big money to buy one without first having confidence that I can get it to work on my carrier's bands.
So I'd like to start this discussion. Has anyone tried anything? Successes, failures, please post them all!

This (QPST) is something I have no experience with,but,interested in the subject:
I'm good with the band support (for now) as what's available in my area,with my carrier,is supported (Bands 2 &4 on T-Mobile US,no Band 12 or 66 yet),definitely would be nice for at least Band 12,if possible,as I believe my area will get it eventually.
One side note & a positive one at that:
My MiMix locks-in on a signal & has better/stronger connections than any phone I've used to date. This was really noticeable while commuting back & forth to work today,unbelieveable signal quality.
IDK if the ceramic body is better vs other materials,but,recent flagships from HTC/Samsung/LG pale in comparison vs this phone.
i have MI MIX in hand.
I think we need MIX Diag Driver to make it recognize from pc. MI5 Diag drivers are not the same

I've heard the Mi5 diag drivers were usable on the Mi5S, which is the same SD 821, so that's strange. What happens when you put it in diag mode and plug it in? Can I see a screenshot from device manager, or some evidence of what the device is?

I've got one in hand in the states (where I actually do need to unlock band 12 for T-mobile) and a patch cable I made handy in case this thing goes brick mode from us trying stuff, I'm game to be the guinea pig for science.
Fair warning though, while I'm a web developer that's very comfy with terminal, I'm new to the android ADB world, so pretty detailed instructions / links to guides will be needed ha!
Good luck Ken, I hope you are able to crack this bad boy.

Is that band 4 only on LTE? I've seen many spec sheets and the carrier I'm on only has band 4 for 3g.

this is what I have gathered from various sources (so yes Band 4 is both LTE and 3g)
Tmobile
LTE Frequencies:
1700 MHz & 2100 MHz AWS band 4
1900 MHz PCS band 2
Lower 700 MHz band 12
3G/4G Frequencies (WCDMA):
1700 MHz & 2100 MHz AWS band 4
1900 MHz PCS band 2
2G Frequencies (GSM/GPRS/EDGE):
1900 MHz PCS band 2
ATT
AT&T 4G HSPA and HSPA+ use 850Mhz(Band 5) and 1900Mhz(Band 2) bands
LTE uses Band 17(700Mhz), Band 5(850Mhz), Band 2(1900Mhz),
Band 4(1700/2100Mhz)
LTE B29 (700)
LTE B30 (2300 WCS)

That still doesn't mean the WCDMA Band 4 is enabled. It's possible to have LTE band 4 and not have WCDMA Band 4.

Yes....was just giving the bands and frequencies I know for two GSM carriers in the US. Monitoring the bands at various locations by something like signal check lite (much easier to use/read than lte discovery IMO) would be only way to tell.. If I recall correctly this device has 3g at 850,900,1800,1900 so there is no band 4 on 3g it seems... Although band 4 (1700/2100) COULD be a 3g band too for some devices. Someone with better knowledge can chime in here. I might be wrong.

Update: I have actually successfully forced band twelve with NV values (I can see it stick and unwind the value to see that band 12 is allowed after a reboot). I followed about 10 diff guides to get my bearing on working with the Qualcomm editors and maintenance programs.
Sad to say: the modem in the Mix simply won't do band 12. I talked with a few folks from the Xiaomi Reddit Discord and they confirmed my suspicions that with Xiaomi (with a few exceptions) it is usually hardware that's keeping you off of a band.
I don't personally think there's any amount of software hackery we can do to get bands unlocked.
Edit: I am quite comfortable in ADB / SU and am happy to try any and all suggestions out on my phone in addition to what I've tried already btw. Please do let me know if there's something you think I may have missed following the various unlock threads.

Sorry to hear that the band could not be tapped into...
yes most likely a hardware thing-like Samsung (some of their models exclusively for Latin america have u.s bands but the 'international' variants of the same models will not do the U.S bands no matter what...
I actually opened one of them (got a damaged T239M) and found indeed that the motherboard is different...(so much speculation and folks asking/trying to flash S. American firmware on like the T705, T239 etc, myself included (not possible anyway even if going through TWRP and flashing modem files etc...bootloader and pit all different..so nothing would change with the other parts of the firmware)
so it is highly likely in this case that the modem will not do bands 12, 17 (ATT) and 29, 30 (ATT). However, it is impressive that for a China phone this will even do bands 2, 4 and 5. Huawei models (again supposedly international) except for some variants of the smaller 5-5.2 inch models (not p9, p8, P8 max, x2, t3, t3 pro, or m3 (some of these are the tablet phone types) and numerous other Chinese phones will not do anything more than 1, 3, 7 and then maybe 8 and 20 or a 28. (all useless for North America). Huawei has an M2 variant that has US bands and also on their smaller phones (certain versions)
so for the Mix, you at least have LTE 2, 4 and 5 (though of lesser importance).

So far my experience is that if the band isn't listed in those spec sheet it isn't there in the hardware (apparently a very Xiaomi thing to do). I'm finding that they rarely software lock you out of the bands, it's usually that their hardware simply doesn't support the band.
Hi all, I purchased nokia 6 (ta-1000) 2 months ago and was satisfied. Problem was i work in dessert area and my phone unable to use 4G band. After many research i found that this nokia 6 doesn't support other 4G bands except china country coz its chinese variant. so my question is does Nokia 8 have many variants too? If yes then can you all guide me? i as am planning to buy nokia 8 and dont want to end up having same 4G band problem like nokia 6.
I have the TA-1004 version. It works in Southeastern Europe with the 1800MHz LTE frequency my phone provider has, also tried it and it works on the 2600 4G frequency from another local provider.
These 2 are confirmed, but there's also the specifications info that the local seller has on the website, which includes all these band frequencies for 4g: 700 / 800 / 850 / 900 / 1700 / 1800 / 1900 / 2100 / 2300 / 2600
So I'm guessing TA-1004 should work with all of the above.

Go to your phone carrier's website and check what band frequencies it has for LTE/4G. Or a google search. That's what I did.
