[Q] Desire Z on T-mobile - G2 and Desire Z Q&A, Help & Troubleshooting

So I finally got a replacement Desire Z after my last one was fried (see my other posts) probably from months of hardwork at high CPUs.
Problem is I'm in the US for a while now (and this is a Swiss phone). I have the stock Swisscom firmware on. ISTR it was a PITA to root and install CM on so I haven't yet bothered.
My question is this: using my tmobile simcard, the phone only gets EDGE. Suck. Please can someone tell me this *isn't* a hardware problem? If I flash CM or switch some funky setting will I get 3G / HSDPA speeds?
Thanks for any info.

[Q] Desire Z A7275 (At&t 3g version)

So I've been using an unlocked g2 on At&t for about a month now and I absolutely love it. I recently found out that the Desire z A7275 model will support At&t's 3g bands in the US. Because of the 3g compatibility, I am most likely going to switch.
I currently have my g2 temprooted and overclocked. This may be a silly question but...the change in band frequency on the Desire Z A7275 won't change anything as far as rooting, will it?
Thanks
Not at all. They are essentially the same device. Using an unlocked/unbranded NAM Desire Z myself on AT&T and have had no problems rooting, modding, etc.
I have the A7275 on AT&T also. Perm rooted (with SuperCID,S-Off) and overclocked no problem.
On a side note, the Bell stock ROM is missing HTC Locations and Car Panel. But I use Google Maps anyway, and I find the car panel to be kinda useless.
The Bell stock ROM comes with a good amount of bloatware. But I was able to remove most of it with Titanium Backup, and the rest with an app called Absolute System Root Tool.
You guys *should* be able to use a custom ROM like Virtuous to keep Sense but go with a more stock Sense ROM.
I thought about getting an AT&T one and staying with them, but their data network in my area is freakin awful. Been with them 10 years, since they were SouthwesternBellWireless, and finally switched to T-Mobile for the G2. My coverage isn't any better, but at least when my phone says '3G', I get 3G speeds. Plus it's ~$50/mo cheaper for 2 phones.
LOVE the G2/Desire Z tho.

Using custom ROM's isn't an issue. I am running Cyanogen 6.1 as I'm not a big fan of the Sense UI. Cyanogen's ROM feels much snappier on the device and is a cleaner, more basic look overall.
From my understanding, once you are Rooted and have S-OFF, any ROM that is compatible with the G2 will work with the Desire-Z. They did merge the two forums into one. These are the exact same devices, just with different band frequencies.
I know this is off topic, but as a former CSR for AT&T Mobility, I have absolutely no idea why you would go to such lengths to use their service. Is T-Mo just not available in your area?
Question, where did you guys get your A7275 from and for how much? I want one

Trust me, if I could get out of at&t's service I would. Unfortunately, I'm on a family plan with 4 lines. I havent upgraded in years, so technically, my contract is up. However, the rest of my family upgraded this past summer so I'm stuck with at&t for another 2 years. Early termination fees are too much and I can't afford to go pay for my own plan on another carrier. And, on top of that, T-mobile just arrived in my area and only has one or two towers.
Another question though: I've seen some unofficial alternate color schemes of the g2/desire z (black/blue). Does anyone know if there are any alternate versions of the 850/1900 3g desire z?

I think that black/blue one was a prototype or at least an early idea for the colour scheme. There's no news that I'm aware of on any alternate colour schemes at the moment.

T-Mob coverage has not been great in my area (although I haven't really investigated it too thoroughly in the last couple years). I also require international roaming service for work, and AT&T is the best for that.

I got mine from Negri. They were great. They have webchat feature, and the customer service rep was very helpful, and was able to confirm the phone was in stock. I got a shipment confirmation about 2 hours after I placed the order, and the phone was in my hands 2 days later.

[Q] speed problems hspda

Hi guys,
Im having issues with connection speeds though hspda on my hand set (tmobile uk).
Im getting really really poor speeds, if i download something of dropbox it can take an age - yet if i download the same file from my wifes desire hd (virgin mobile - basically the same network just rebranded) she gets it very quickly.
i then tested a bit torrent file and never got past 5kBs on my phone but hers reached 97kBs and held. Mine would drop down to 500bs most of the time as well.
The signal strengths are the same and i have tested this in a quiet a few locations now and the results are consistant.
Also ive given up streaming tune in radio on my phone as it constantly drops and now use the wifes virgin desire hd as it working correctly with no drops.
My sim is now 11 or 12 years old now and im wondering if that could be the cause of the problems im having with connectivity.
Has anyone had bad speeds running an old if not ancient card like this?
Have they changed the design of the chips with the event of 3g?.
when i purchaced the original phone on the contract i dont think 3g was avalible then so im suspecting that could be the cause,
can anyone shed any light?
thanks
Your sim is so old? :O so you cut the sim to make it fit for the hox. Order a new one mate. Old ones mostly cause some trouble. You should be able to order a new sim from your provider for a few bucks or even for free. Try it out. And of course you can install speed test to see how the transfer is.

thanks mate, ive just got a replacement free of charge, the speeds are 1000x better, only problem now is my imei number is no longer there and the phone wont show my phone number.
i think they were a bit suprised that it was working at all at the age the card was.
why do htcs always reset the home screens on sim change, blooming annoying!!.
just fixed everything, got the settings from tmobile and i now have imei number, phone number etc, and the phone running a lot better!! i cant understand how a sim card could make the phone run so badly, either way its had a new breath of life and running much better,
anyone that has an older sim get it changed, i think mine only supported 2.5g as i wasnt getting any speed above that.
thanks again

[Q] GSM radio fail?

Hello One X forum!
So I received a One X I bought secondhand from eBay today. It has problems though; although the phone accepted my sim card and makes calls, the mobile data isn't working. Admittedly, the reception isn't great around here, but even my very elderly HTC Legend can get GPRS (network only goes up to HSDPA anyway) data just fine. Also, while the wifi radio appears to work, it can't keep the signal even from just a few metres away from the router. The phone was originally bought in the UK, (which is where I am not) and appears to have been unlocked from T-Mobile. (I'm on Vodafone.)
Yes, before you ask, I checked if the phone is blacklisted or blocked, and it's not (though if anyone has another way to double-check if it's not blocked by T-Mobile specifically, I'd appreciate it). I don't think it has been rooted (UI looks like stock) and I don't know how to check if it is, or how to check the HBOOT or whatever either. It seems to be a GSM radio failure, which is probably why it was so cheap (of bloody course). Is there any way to fix it, or am I stuck with selling it as spares?

radio upgrade?

hi guys, im in the u.k and owened this phone for over a year..
just wondering if there are any radio upgrades available for this phone as the reception is seriously poor, now im not sure if i was just unlucky in getting a bad handset, or if its to do with the frequencys used in the u.s & u.k. (i checked before i got the phone and the frequencys should be the same)
when im in the house i put my sim card in my old htc desire z & turn on wifi hotspot and use my glide using wifi.
so, i was just wondering if there were any tricks i can do to improve reception such as flashing a diffrent radio version?
thanks people..

Samsung S4 3G issue

Hi guys
I’m new here and I need your help.
I have Samsung S4 International bought on amazon in US, no simlock.
I use this phone in Ireland in Europe.
Everything was ok until a few months ago when I lost 3g connection. Science then my phone is working in 2g only mode (gprs/edge speed)
Phone was running on stock rom android 4.4.2, I thought it is a software issue so I rooted phone and installed CyanogenMod. Unfortunately it did not help 
Phone still synchronise with 2g network instead of 3g even in capital city next to BTS.
I was wondering is 3g module broken and what could be a reason of that? Do you have any idea how could I fix it, what would be a cost of doing it and is it even worth it.
Except that, phone is working ok. GPS with finding a fix is a little bit slow but this is not a big issue.
Thanks in advance
FMX
Current details about phone:
GT-I9505
4.4.2
Kernel 3.4.0-cyanogenmod-g2ab6e0f

Build cm_jfltexx-userdebug 4.4.2 kot49h
LOL ....Compare S4 and G4.
