I had question on 3G network bands. I know Tmobile HTC TP2 has 1700 and 2100 UMTS for 3G coverage which is not compatible with AT&T 3G network.
Is there any way to make it compatible with AT&T 3G network? By upgrading ROM? By making some hardware changes -> How and Who would do it?
Thanks for your time. Thanks.
not possible at this time
i think if you could force hardware to work at frequencies it wasnt built to would have people buying alot less branded and locked phones.
No, the device itself is technically able to receive these frequencies, but the real problem lies with the antenna. Olipro once said he forced the frequencies on one of his devices by somehow modifying the SPL or radio (something like that, anyway), but he didn't receive any more frequencies than he did before, because the problem is with the antenna. The antenna cannot receive these frequencies, so your device is stuck with T-Mobile's 3G frequencies.
Guys, its the same reason as with the Tilt/HTC Kaiser operating on T-Mobile (although I think it was a diffrent piece of hardware. I remember a website briefly had a hardware mod that was capable, but ultimately the parts were as much as the phone....screw that
Does this apply to the EDGE network also? I recently upgraded from my AT&T FUZE to The T-Mobile Touch Pro 2 for the larger screen. I was disappointed that I lost access to AT&T HSDPA/HSUPA network but after reading this post I understood.
But the phone says I’m connected to EDGE but my average speed is 36K, equivalent to GPRS. On my previous FUZE with 3G disable & HTC 620, even a few dumb phones, the EDGE speed was always 200K+.
I don’t think is related to my location, I normally get great connection at home and at work and both locations same speed. I don’t think it is the ROM, I’ve tried a few with the same result, I’m currently using the latest Energy ROM Phoenix.
Edge & GPRS
No, Edge and GPRS are both quad band so if your device will connect to one, it will connect to the other when the signal is available. Only 3G is typically dual band. The Tilt2 picks up 3G on 850/1900/2100MHz so it has one crossover frequency with TMO, but I don't know anyone that has tried picking up 3G on TMO with a Tilt2
No, there are no limits on EDGE frequencies, as all the Rhodium variants are quad band GSM and EDGE capable, and they all support the same GSM/EDGE frequencies. It's only the HSPA frequencies that are different across different Rhodium variants, because the frequencies are so fragmented with different carriers and in different countries.
Thanks for the info.
It's amazing we put a man on the moon(over 30 years ago!) and have made so many technological feats but this we can not do...
If the phone was built one way, it's gonna stay that way.
I don't think there has been a single person in the existence of the earth that has taken apart one of these devices and replaces the radio.
Please prove me wrong.

It is not that it can't be done, it is just not worth your time to do it. You would be better off selling your TP2 version and getting one the works with your bands.
Thanks for all the information
As I understand to accomplish the thing that I intend to do would need total hardware replacement.
However I wonder if there are any techniques and/or ways to enhance download/upload speed with EDGE? The current EDGE speed on AT&T is very slow. I believe T-Mobile EDGE speed (I used Blackberry Pearl 8100 on T-Mobile earlier) was comparable to 3G speed on AT&T (I have Blackberry Bold 9700 from Office on AT&T). Why EDGE on AT&T is very slow?
Am I doing something wrong with communication settings? I'm using "wap.cingular" as my APN (Access Point Name).
Thanks again for all your valuable inputs.

can you put yourself on the moon? its not that easy. you can remove the radio and corresponding internals. but you have to remove it from a working device thats already capable of those frequencies. and then why not just use that phone? its so pointless.

Try a different radio, I'm using 4.49.25.88 and my speed increased from 37K to 102K, still sucks but better. I also read on the here that switching GPRS authentication form PAP to CHAP may help also. The switch didn't work for me. I know I can get up to 200K so I will keep trying tweaks.
4.49.25.88 ? Where do I put this in Connection Settings?

It's not a connection setting, it's a whole new package of code for the radios in your phone (phone, EDGE, 3G, bluetooth, wifi), and is flashed to your phone just like a full new ROM (but you can keep whatever ROM you're currently using, even if it's stock).
Pending a test I'm trying to run here, this may also help with the EDGE vs voice issue you've posted the other thread about...I think a different radio might help you with that as well.

You can find radios in the ROM section.
I apologize, I feel like we're hijacking this thread. But here's a pic of my current speed using mobile speed test. Must better than it was before.
New Radio didnt help
I flashed Hard SPL and then 4.49.25.88 radio on Tmobile HTC Touch Pro 2 (with WM 6.5 official ROM).
I didn't increase the internet (download/upload) speed. With earlier Radio, the speed topped at 76 k bits per second, lowest at 19 k bits per second and averaging between 30 to 45 k bits per second. (I did about 10 to 15 tests using dslreports.com/mspeed)
With 4.49.25.88 radio, it never went above 40 k bits per second. Averaging between 19 to 25 k bits per second. Actually reduced speed compared to earlier radio.
I'm not sure what should I try next???? please help!!!

Try .91, trust me you will find one that is perfect for your carrier and area.
I flashed Energy ROM with .88 radio, it did improve download speed. But still don't receive calls while using data.
Hello everyone, i recently bought a zenfone 2 (WW), but there is one thing that's bothering me, the LTE speeds.
If you check this page of the Asus internation website it says that the zenfone 2 has LTE Category 4+ for download speeds up to 250Mbit/s, and it also shows the positions of all the antennas (there are 2 antennas for the sim 1, so carrier aggregation should work). (attached file #1)
This image of the US presentation confirms the support for CA 250Mbit/s. (attached file #2)
But if you switch to the specifications page it says that it is a simple category 4 150Mbit/s. Now that is what is listed on almost every web site (cat 4 150).
Another thing is the modem, in the specifications page it says it is an intel 7262, which, if you check intel's website is a category 6 300Mbit/s modem. (attached file #3)
As you can see this is quite messy, has someone figured this out? Can someone enlighten me? Thanks for the help.
All I can tell you is that higher speeds I've seen were around 70mbps with band 4.

Thanks for the answer, here in Italy i managed to get 80Mbit/s (2600/15Mhz i believe it was), but i still don't think this is 4G+, it should almost garantee speeds of 100Mbit/s and higher. Has anyone tested it in a 4G+ area?
It's really strange that no one knows anything about this, i mean, it changes by a fair amount the longevity of this phone. I think i will probably write directly to Asus to see if they know something...
No one knows?? Crazy... I will write to Asus Italy support and try find out.
Upon further investigation i found something on the TW zentalk forum:
http://www.asus.com/zentalk/tw/forum.php?mod=redirect&goto=findpost&ptid=86120&pid=401706
Looks like someone managed to get 170Mbit/s with 4G+ network (with a Z00AD), so this would confirm the cat4+ capabilities (250Mbit/s), which both the ze551ml and the ze550ml should have (having the same intel xmm 7262 modem). More detailed specifications should have been given though....
K so... I got a message from verizon to enjoy my new faster speeds because they've rolled out the new LTE-ADVANCED in my area. So I ask what's this? Look it up and see a list that starts with the note 5 and newer phones.(note 4 not on the list)
Is this hardware or software?
I'm currently on note4Grace and loving it.
I don't see any indication that there is anything different about my lte signal. No + or -A so if I did have LTE-A how would I know?
I apologize if this is a repeat (redirect appreciated) thanks for your time
So I am planning on ordering one of these soon but having read the forum there's been some concerns around LTE connection. I was quite pleased to learn that 20x was supporting a a lot more bands than any other "normal" Chinese phone would. That said, I am getting second thoughts now to learn that people are not getting the best LTE connection (HSPA + on Att?) and a lack of band 28 which may not make for an ideal LTE experience.
What are your thoughts and how's your experience been when it comes to data (particularly the LTE) connection?
Thanks in advance.

Many things, read through the forums, for me the differences are livable, to others its not. Buts all based on what you want from the phone and what you use. I dont live on my phone, so for me for example, "whatsapp" is useless, to others they cant live without it. But for everybody the need is different.
LTE+ on bands 4 and 7 in Canada, New England, and New York. Very fast data connection. L29 model.

I was worried about speed too before I bought. Band 28 is very common in Australia so the fact it is missing from this phone had me worried.
Thankfully my experience has been wholly positive - check out my up/down speed on dslreports here: (I can't post links so you'll need to take out the linespaces and add back the periods)
www
dslreports
com/speedtest/44320783
Notice that mine is currently the fastest speed in the last 400,000 tests nationally using my mobile provider (Telstra Bigpond). The second fastest is an iphone, clocking in at half the download speed I'm getting using my Mate 20 X.
(Note: I have the "LTE high-speed mode" enabled in settings)
I'm in the UK and use bands 1 & 20 on Vodafone, very quick speeds and never noticed any issues with connectivity
I bought this phone for several reasons, the great Camera, rootability, but Mainly for 5G and faster data. It's Rooted with .037. Since I had my years old sim in the phone all I was able to manage was about 35 Mb/second on 4G. So I headed to the ATT store and got myself a new sim card for it. On the way home I did a speed test and got 75Mb/second, 5G. Great, I thought. So when I got home I wanted to do some speed tests, and it was on 4G. I have an anntlent booster in the house due to having a metal roof. It has the following bands. each can be adjusted Individually:
LTE Band 12 Uplink (698~716MHZ) Downlink (728~746MHZ)
Band 13 Uplink (776~787MHZ) Downlink (746~757MHZ)
CELL Band 5 Uplink (824~849MHZ) Downlink (869~894MHZ)
PCS Band 2 Uplink (1850~1910MHZ) Downlink (1930~1990MHZ)
AWS Band 4 Uplink (1710~1755MHZ) Downlink (2110~2155HZ)
I turned down all the adjustment screws and took the phone outside. It connected to the PCS band 2, 5G. Took it back into the house, it was showing 1-2 bars. So I turned up the gain on band 2. The signal strength jumped up, but the phone instantly jumped to 4G. I thought it was supposed to go to 5G on a strong signal, then fall back to 4g if necessary. I tried *#*#4636#*#* and setting the phone to "nr only", but you night as well piss up a rope, the phone ignores these settings and resets itself to "unknown"
I fiddled with it some more and got a solid 5G icon. But only 5 Mbps download. For a couple hours messing around, and re pointing my antenna to another tower, I finally got a 4G signal on AWS Band 14 with 15Mbps, less than I was getting with my old 4G Sim.
I would like to see this thread developed with better Radio versions, hopefully ones that can be actually locked to what they are set on, whether it be those who want to avoid 5G or those who want to enforce 5G. 5G IS definitely faster in my rural area. Software I used to help diagnose this, and cell tower locations: Network cell info (an older version from an old phone extracted with apk extractor because the new one on google play kept crashing) Open Signal, and I tried Network Signal Guru, but it did nothing on this phone. Please post any ideas you may have concerning Radio connectivity, Booster (resetting) better software and firmware, etc.
@GivIn2It I've changed the prefix of this thread from "Development" to "General" as it didn't qualify for the first. Please review the stuck guidances at the top of the forum and do not change the prefix back.

Does AT&T even have real 5G (NR) deployment in your area? If so, is it NSA? If so, it probably uses B2 as the LTE agg link. According to the site below, ATT is supposed to be on n5/850mhz. You need to find out how ATT handles it's NSA deployment, but I guess you need to have B2 + n5 at a minimum.

Not sure if the Network Signal Guru betas are fully public yet, but they work great with the Pixel 6. No band locking though.
Contribute device capability info if you can to the cacombos site. We won't learn anything about what the Pixel 6 is capable without field testing. There's no documentation or data sheet for the "new" 5123b modem in the phone.

Thanks for that info. Apparantly, there is some aggregation going on. When the phone switches to 5G, none of the software including the Phone Info page will detect what band it's using. Phone info does show NR Available: True and NR State: Not_Restricted.

It looks like my device has already been added to the Cacombos database. I can't find a link to that beta. do you have one?
It doesn't matter if your device is already listed. It's incomplete.
And I don't believe I can share the alphas or betas.

OK, then. How am I supposed to obtain that device capability information to upload to Cacombos, I don't have software capable of obtaining all that information from the phone. I'm willing to share information if you're willing to share the software that can obtain the information.
Please read the Shannon instructions. You don't need NSG or other tools.
The "Shannon instructions", could you be a little less specific?

Problem is this, not sure the instructions are compatible:
This works with Shannon modem devices except Samsung Exynos device (eg. Pixel 6 and 6 Pro). For Samsung, please use Exynos internal logging by exposing modem to Scat, ShannonDM or Airscreen. Require root.
Open terminal with adb shell or with Terminal app.
Start logging with in superuser (su)$ su
# modem_logging_control START
Turn on Airplane mode and wait for 5-10 seconds. Turn off Airplane mode.
End logging with command# modem_logging_control STOP
You can find logging file now in `/data/vendor/slog`

Instructions under "Samsung device" references OneUI shortcodes which won't work with the PX6/P
It works. The wording is incorrect. It works for non-Samsung Exynos devices.
This is how we gathered the combos until NSG started working.
But the reason why we need more data is because one report from one phone only reflects the country they're in and what their carrier supports.
It's like cellmapper, more data is better.
I think I have figured out the problem. The Pixel 6 Pro doesn't like it when I have all my gains all the way up, at least for 5G. When I set the bands CELL Band 5 Uplink (824~849MHZ) Downlink (869~894MHZ) and
PCS Band 2 Uplink (1850~1910MHZ) Downlink (1930~1990MHZ) to a little over halfway, the phone regularly connects to 5G, especially when downloading. The signal icon on the phone varies between 2 and 4 bars. Download speeds about 2- 15 Mb/s, which is about a third of my better 4G speeds. But I get to see a pretty 5G icon on my Phone. Superb! My next step is to buy a honkin Yagi to replace my pathetic one, and do some signal searching to see if I can pull in that 75Mb/second tower. If that doesn't work, It's just wait for ATT to improve their 5G here, as I have determined that the Pixel 6 Pro is (mostly) working correctly out of the box, it is looking for the best signal, and if that's 4G, that is what it will switch to. Being more of a hardware guy, I think I can accomplish more with external equipment than I can monkeying with the guts of the phone. Rooting was scary enough. But I'm still open to flashing a better radio, when someone comes up with one.
