2.08.50.08_2 I LOVED...

2.11.50.20 I hated.....

2.12.50.02 was VERY nice...

2.10.50.26 Just blows them all away though imo... It is the best radio for Florida area anyway...

Using the June 26th Energyrom

Tested each on heavy call/text usage + watching movies + using pandora radio...

2.12.50.02 would have been the best but it switches too often between H and 3G which burns battery life! Where 2.10.50.26 makes up its mind and picks one and sticks with it till you move from the area...

Hope this helped you USA TMO users..

I live in the Mt Rainier foothills and while reception doesn't cut off completely for a few more miles, it gets pretty spotty indoors. I have the rest of the family running on UMA, and fortunately my HD2 manages to keep a minimal voice connection from here (and I use wifi for data), but I would like some recommendations from anyone who has tried multiple radios under similar circumstances.

Thanks!
[HD2 Windows Mobile 6.5 ROM Development] Matt V:
Anyone with any radio input from the Dallas/Fort Worth Texas area? I'm on 2.11 right now but it frequently changes from 3G to H and I'm thinking that's what's killing my battery life.
[HD2 Windows Mobile 6.5 ROM Development] cwwjr1681:
They are doing A LOT of upgrades in dallas atm 2.08.50.08_2 or 210.50.26 is the best radio for that area atm. I recommend 2.08.50.08_2 but try them both... Few people in the USA use anything above 210.50.26 unless you live in the boonies where it wont switch networks so often. ANYONE IN THE FLORIDA AREA TELL ME THE BEST RADIO YOU HAVE FOUND FOR BATTERY LIFE..... In a reply please.... TY in advance...

Anyone find the best use for in and around the Chicago area?

Oh, and a link to how to install/change the radio would be amazing :) haha
[HD2 Windows Mobile 6.5 ROM Development] dotnetguyaz:
No idea about the Chicago area... you can use the link in my sig to learn how to flash your radio.
[HD2 Windows Mobile 6.5 ROM Development] dirty k:
Agreed....also in the DFW area and currently using 2.08 on NRG's Jun26. I have had no problems with it or 2.10... but went back to 2.08....Have not tried 2.11 or 2.12 but curious on those two.
[HD2 Windows Mobile 6.5 ROM Development] BatVette:
I'm running the new TMO 2.13 ROM...I see where most people playing about with the various radios are running 2.11 ROM? Is there anything I need to be wary off with the various Radio files while running 2.13? Currently looks as if I am running Radio version 2.10.50.26 as part of my 2.13 ROM update a few weeks back.

Just want to make doubly doubly sure before I start loading radio setups that I won't blow things up too badly. Currently getting a lock up when I try to hang up from a phone call...sometimes goes OK, other times locks up the phone and gives me a CPROG error requiring a soft reset.

*sigh*

Thanks!

DID I just Brick?

HELP!!!!!!!!!!!

Flashed Leo_RADIO_15.28.50.07U_2.05.50.11.

Flashed completely. USB sound turned off (windows sound) removed from USB after screen went black..and thats it.

I was was running latest Dinik themed ENERGY ROM.

What did I do? Got a 1024. Bought phone off of CraigsList. Luckily from someone who is calling T-Mobile right now.
[HD2 Windows Mobile 6.5 ROM Development] sumflipnol:
Can you go into Bootloader? If you can, you should be able to flash another (more recent) radio-rom.

The best thing to do is take out the battery for 5 minutes. Put it back in, go into bootloader, flash a radio-rom, and hope it goes well.

If you can't get in Bootloader, you might be in hot water.:(

On a sidenote: I thought we were only allowed to flash radio-roms 2.06.50.xx and up, as the 2.05.xx.xx radio-roms are old and (as you may have proved it) incompatible with our HD2s.
[HD2 Windows Mobile 6.5 ROM Development] dotnetguyaz:
Wow, 2.05??? I haven't seen that version in awhile!!! I have to agree with Sum...
[HD2 Windows Mobile 6.5 ROM Development] fcreeves:
No Boot Loader...Luckily T-Mo is sending a replacement to the guy I obtained-traded (within 30 days) it from. Heart was pounding last night!

So, that's what I get for late night flashing...I thought I learned my lesson long ago to never MOD late at night...or when tired. Those were fresh Walmart purchases for consoles...with no worries. An HTC obtained thru 3rd party is little differ. Now I have to flash his 360 drive for free and throw him a few DVD-DLs. Well worth it!!!

So, I need to do what I have preaching to everyone for years READ!!!!!

i seem to be having a lot of dropped call issues with the 2.12.50.02. when it happens the people i talk to usually say it was their phone, except for my friend with an evo (and i usually have good signal strength) but it still makes me wonder. battery life seems about the same across the board for me, so for the sake of arguement i have been thinking about flashing an older one back to the phone.

Flash with SD method?

can you flash a new radio using the SD method? My comp doesn't like USB method.
[HD2 Windows Mobile 6.5 ROM Development] Playa4Life352:
Just a quick question..

I was at stock 2.08.50.08, warranty replacement by HTC, and haven't upgraded the radio on my new device yet. Am I supposed to do upgrades to 2.09, then 2.10, etc. Or can I just upgrade straight to 02.12.50.02 without any problems??
[HD2 Windows Mobile 6.5 ROM Development] sumflipnol:
You could flash any 2.xx.50.xx radio without any problems (no need to go by steps). Just make sure it's 2.06.50.xx and above.:)
[HD2 Windows Mobile 6.5 ROM Development] Playa4Life352:
Got ya... This .12 radio seems to be getting worse reception than stock..... Anybody else getting negative results??
[HD2 Windows Mobile 6.5 ROM Development] Playa4Life352:
Yes just name the .nbh to LEOIMG.nbh, and make sure your SD card is FAT32 partitioned!!!
[HD2 Windows Mobile 6.5 ROM Development] sumflipnol:
Well radio performance depends on your location (and sometimes ROM), so maybe you could post your city/state and see which performs best in your location.
[HD2 Windows Mobile 6.5 ROM Development] :
I doubt those errors have anything to do with your Radio, but as long as the radio you flash is not a x.xx.51.xx, you'll be fine, it will either get better or worse, but should not hurt your phone ....

If you are unhappy with the stock rom and it keeps crashing , maybe you should investigate a custom ROM ....

trying to figure out the best radio for the Houston area, just booted Kumar's latest ROM and having some issues with the signal switching from EDGE to 3G constantly
[HD2 Windows Mobile 6.5 ROM Development] abs99:
I've been running Kumar's 2.4 beta with 2.12.50.02 and seems to be quite good. Previously had been running 2.10.50.26 and was very stable but somewhat worse battery than 2.12.

Which radio are you running and which version of Kumar's ROM. The constant switching was a known issue with the original OEM T-Mobile radio.

Andrew

Just booted Kumars V2.3 and the current radio is 2.10.50.26

Was thinking about throwing in the one you mentioned, found any downsides to it?
[HD2 Windows Mobile 6.5 ROM Development] mastajest:
Try re-flashing the same radio. Sometimes switching to a new ROM can mess with the radio.
[HD2 Windows Mobile 6.5 ROM Development] abs99:
Recommend upgrade to 2.4, runs smoother than 2.3. Also, the new radio seems good, not doing anything funny. Suggest further questions should be posted in the ROM thread so we keep this one focused on radios.

Andrew
[HD2 Windows Mobile 6.5 ROM Development] aggieman2k7:
May try this first. This radio came with my device when I bought it. I don't think the last official HTC update to 2.13 changed the radio, correct?

Anyway, Andrews right. Thanks for the radio suggestions!
[HD2 Windows Mobile 6.5 ROM Development] sumflipnol:
Official ROMs usually come with radio-roms. The T-Mobile 2.13 ROM update contains radio 2.10.50.26 while the original T-Mo ROM came with a 2.08.50.xx_2 radio.

3g problem

my 3g connection keeps disconnecting and i have to manually switch it back on. any ideas? i am using wind mobile in canada. i used every radio. same problem. i am also on the latest kumar rom. please help me, its getting annoying.

1. Fixed custom lockscreen not working issue.

2. Fixed data connection switch bug in communications manager.

could it be that? do you have the latest build? ( i dont know what the bug was, and ive not tried the rom, so just a shot in the dark)
[HD2 Windows Mobile 6.5 ROM Development] abs99:
Just noticed a very interesting fact about all the radio roms I've downloaded so far:

Every radio firmware up to (but not including) 2.12.50.02 has a file size of exactly 24,629KB. In contrast, firmware version 2.12.50.02 has a file size of 24,500KB. Clearly, something fairly substantial has changed with this new firmware. My guess is that prior radio versions were "calibrated" differently with a range of values for certain variables, but that the underlying code was most likely constant. In the case of 2.12.50.02 there must be fewer lines of code which in my mind implies at least part of the code was rewritten . . .

Does anyone have any insights into this?

Andrew
[HD2 Windows Mobile 6.5 ROM Development] abs99:
I've rolled back from 2.12 to a 2.10 radio as the "in-use" battery drain on 2.12 seems much worse than I had before. As a heavy user, this radio was not good for me. I think for a light user, might be quite good. My hope is that in the future, we will get a new radio based on 2.12 design that can provide very low stand by battery use but behaves more like one of the better 2.10 radios during phone usage.

Thanks, I found it right when you posted that...:)
[HD2 Windows Mobile 6.5 ROM Development] dotnetguyaz:
I have a question... Did you flash a new ROM and the radio at the same time or did you flash the radio on to an existing ROM. This can affect battery drain as when you flash a new ROM and a new radio, the battery stats are reset and the system needs to rebuild the statistics. This will cause the device to use more battery for the first few recharge cycles.

Typically, when testing a new radio, I flash the radio and ROM at the same time then give it at least 3 full recharge cycles (Letting the battery completely drain and then recharging with the device off to 100%. Then repeating the process at least 2 more times).

Once I do that, then I start measuring how the battery drain is. On the 2.12 radio, I have gotten excellent standby and aggressive device use stats. Not quite as good as I got on 2.10, but the thing that keeps me using 2.12 radio is the reception. I can take a little more battery drain if I am getting reception in places that I never did before.

Leo_Radio_2.12.50.02_2 sucks on my T-Mobile HD2 in TN, USA.
[HD2 Windows Mobile 6.5 ROM Development] dragion:
I feel that I needed to post this info here on this thread for members in the New England area...

Installed radio 2.12.50.02 and concluded with my HD2 it had less battery life performance & weaker 3G data connection...stayed on edge most of the time in my area.

Wifi was slightly worse holding signal compared to 2.11.50.20.

Both 2.11.50.20 & 2.12.50.02 battery life still out performed 2.10.50.28_2 in my case...data signals were slightly better also.

I re-installed 2.11.50.20 and will stick to this radio...unless a better one comes along.

This info is for anyone who is within the Boston, MA area and can't decide which radio works well here...YMMV also depending on your T-MoUS HD2.

Radio: 2.12.50.02_2

Rom: Core Cell Evo Series WWE

Wifi seems stable and call quality is excellent...I will report back in a few days as to the final conclusion.
[HD2 Windows Mobile 6.5 ROM Development] abs99:
I did see a post about this earlier in the thread, however, this is the only time I've ever seen this concept referenced (perhaps you had posted?). In terms of cycling the battery 3x before doing any testing, that makes no sense unless it is a completely new battery. Are you recommending using Task 29?

My process is simply to flash the new radio and then, afterwards, either continue using the ROM that was on the device although I flash new Kumar ROMs quite often (more frequently than I flash radios), or I hard reset, or I install a completely new ROM build. In all cases, with radio 2.12 I had really bad battery drain when in a call or surfing the web although standby was markedly improved with 2.12 versus radio 2.10.26.

Andrew
[HD2 Windows Mobile 6.5 ROM Development] sumflipnol:
This is actually commonly preached in ROM/radio-rom threads, especially directed towards noobs.

This is how it's usually explained (or at least how it was explained to me):

Everytime you flash your phone, its ability to read the battery is impared due to a reset in the battery's calibration). You must cycle the battery ~3 times in order to improve its ability to read the battery, and thus "improve" battery life.

A metaphor taught to me (when I was a noob) was "Think of it as getting your legs replaced. It takes time to re-learn how to walk properly. Likewise, your phone's ROM (and sensors) is replaced. It takes time for it to re-learn how to properly read the battery calibration. <--It may sound stupid, yes, but I do believe it. The first 2 days after I flash my phone, battery life is horrible. Afterwards, my HD2 can last 2 days with normal-to-heavy usage.
[HD2 Windows Mobile 6.5 ROM Development] abs99:
I'm not so sure about this but willing to try it. I have tested out the 2.12 radio for a period of about 12-14 days last time around and the battery life while using the phone (in call or data service) was terrible for me. I know others have reported similar results with this radio. My HD2 barely makes it a day, if that, depending on my usage. I have ActiveSync and WindowsLive e-mail sync, both in real time, either no or just a few texts, perhaps 1-2 hours voice calls, and perhaps 1-2 hours of web surfing. I use e-mail extensively and receive lots of messages during the day. At home I typically have 3G/HSDPA connection, on my drive to the office will fluctuate between 3G and Edge and in the office is usually Edge. The last time I tested 2.12 was with Kumar 2.3 ROM and I'm now on Kumar 2.4.1 rom.

My point of view is that if there was a calibration issue between the battery and the ROM, then after flashing a new radio firmware, you would see your battery levels shift dramatically from where they previously were. I think these lithium ion battery's have a small chip in them that tells the OS some basic information about the battery itself. I've used tBattery and Battlog to view and monitor some of the battery variables and variables such as FULL (mAh) and ACR (mAh) appear to be read from the battery directly. Someone else with more knowledge about this may be able to comment. I have never noticed 2 days of reduced battery life after a ROM flash although the flashing process itself, and installing all my "stuff" over a period of hours usually sucks down the battery quickly after a new ROM flash.

On the other hand, I DO believe that the differences in the Rilphone.dll may have an impact AND this may be part of what is driving the varying reports of differences in battery performance. The Rilphone.dll, as I understand it, is responsible for handling the communication between the radio firmware and the OS. A new radio firmware with differing operating characteristics may require a different Rilphone.dll in order to take advantage of the latest features of the radio firmware (including power saving features). That is the reason why, in other forums on this board for different devices, the Rilphone.dll is often packaged with the various available radio ROMs. This ensures compatibility and proper operation of the radio firmware. At this point, each ROM cook may be using any number of different Rilphone.dll files and it is difficult (impossible?) for us to know which is which. In turn, we are all forced to test many radios to determine which, if any perform well with our selected cooked ROM.

If I might ask, with which ROM are running where you getting 2+ days out of your HD2 and what is your typical usage and signal like?

Thanks,

Andrew

I have a good test location in the Minneapolis area as I get poor reception at work

Radio's pre 2.11 for me have varing batteries and get 0 to 2 bars of recpetion at work but if I go outside I get 3g and 4 bars.

Leo_Radio_2.11.50.20 was a huge downgrade for me for reception but battery was good. 0 bars at work inside or out. I can find the occational spot to get 1 bar reception but it's not consistant.

Leo_Radio_2.12.50.02_2 has great reception 3-4 bars reception most places in work (still 0 bars in some spots) 3g is still rare. Not sure on battery as I havn't run it for long periods yet.
[HD2 Windows Mobile 6.5 ROM Development] sumflipnol:
I am definitely no expert here, so I cannot comment any further regarding the battery calibration's relation to ROM flashing. (I'm just a kid!):p -- Seriously!

When I was looking at how Rilphones work, I encountered a few posts from several chefs who exclaimed that Rilphones don't really matter that much. The Rhodium was my first WinMo device, and the practice of changing Rilphones isn't popular with it. I do know Rilphones were a big deal with devices before the Rhodium. I was just taught that radio performance depends on one's location (and sometimes, the ROM).

The ROM I'm currently using is in my signature. Here in the Bay Area, CA I usually get ~4 bars of 3G outdoors and ~2 bars of 3G indoors whereas EDGE is almost always full bars. I went on a 5-hour road trip (to visit some universities) and I used my phone for GPS the whole time. I was even browsing the universities' websites at the same time.

On a typical day, however, I usually receive few SMS (~10 total), make few calls (~30 mins.; when I'm at home, I usually make long phone calls using our landline since it's easier), use the data on my phone for ~4 hours (this could range from checking e-mails, instant messaging via Palringo, or browsing the web using Opera).

I max out at 2 days without a charge. I think what makes the 2.12 radio so good with battery life, in my situation, is that it conserves battery so well when the phone is in standby. For example, when I sleep for 10 hours, the battery drains only 2%.
[HD2 Windows Mobile 6.5 ROM Development] abs99:
Wow, that is pretty great battery life, especially if you are seeing that consistently. Looks like my two e-mail accounts set to "as items arrive" may be part of the issue pulling down the battery. Also it may be that the Energy ROM has better battery life than Kumar's? Not sure about this since I have not tested the Energy ROM.

I flashed to the 2.11 radio yesterday morning to test it and so far it seems good, battery life was okay yesterday, I'll know more later in the week and will post thoughts, I usually keep a radio on the phone for at least 7-10 days to get a really good feel for how it's doing before making a decision about it.

Flash HSPL3, and read this tutorial to learn how to flash it (and custom ROMs).

Once you complete flashing HSPL3, flash any radio with a ".50" in its name. Do not flash radios with ".51" in its name. To obtain radios, go to the HD2 ROM Development sub-forum and search for the radios.
