1Gb ROM Major Plus for TmoUS HD2

Does anyone think the 1Gb ROM is a major advantage of the TMOUSHD2 over the Euro HD2? Isnt it possible WM 7 or other future OSs will require more than 512Mb?
Also, I've seen in threads and stickies here that any Tmobile US ROM will work with Euro HD2, my question is, what if the size of the ROM is larger than 512MB? How is it possible EVERY TMOUSHD2 ROM will work in a Euro?
I really hope someone can put me right...

Some Conclusions

Dear all
It is my lunch break!! So I have some free time to post some conclusions I reach them after reading many threads in many forms regarding the HD2 t-mobile.
Whenever you looked, there were people says, DON’T do that it will break your device it will burn the motherboard, you will lose it forever it will died, etc..
For a moment, I am scared and changed my mind to get this device!!(I had an universal HD2 for about 3 months and sold it to get the t-mobile because of the RAM and ROM).
It is so simple, my understanding is as follows:
The MAIN/MAJOR problem is the radio, DON’T TRY TO INSTALL ANY RADIO contain the number 51, and/or STOCK HTC ROM for any language because usually the radio is included on that.
You can do the HSPL simply and you can flash it with any custom rom designed for HD2 (noting that there is some rom designed for t-mobile supports the additional/hidden RAM size ) and the rest will treat your device as a normal HD2 512 RAM. READ CAREFULLY IF THE ROM INCLUDED A RADIO.
For Android, you can install whatever you want, because they are depending on SD card and don’t use any windows/rom files.
There are my simple thoughts in this respect, if I am wrong in any part please correct me, because this what I am planning to do with my device, once its arrived (within a few days).
SORRY FOR MY BAD ENGLISH, I HOPE IT WOULD BE BETTER in the next time

Yes, you are correct. For the most part any ROM will work on the T-Mobile HD2 EXCEPT for official HTC or other carrier ROMs besides T-Mobile USA ones. And yes, flashing a radio with XX.XX.51.XX WILL brick your device and it will be unuseable. Just read the stickies and play it safe. If you don't feel comfortable with a step, DO NOT DO IT until you have either read enough to feel confident or asked someone. Hope that helps!

[Q] Difference between HD2 t-mobile version and HD2 european version

I will be buying a HD2 soon and was wondering what the difference (if any) in performance between the 2?
And say if I wanted to dual boot android and wp7 if there would be any performance issues?
The difference with the frequency bands is not an issue for me.

tmous is easier to make a mistake and brick, and the regular hd2 has more range of available roms. other than that you shouldn't see any difference.

I thought that's the other way around. the TMOUS version has more roms and not so easy to brick.
to the OP, the band they used is different. the size is bigger on the TMOUS version. the rom size is twice as big as the international version.

regular hd2 can take any rom any radio, but the tmous hd2 hangs with non tmous roms, and dies permanently with non tmous radios.
There are very very few (half a dozen, maybe) roms that say specifically FOR tmous, and they are android roms that make use of the extra rom space rather than an sd card ext partition. these roms would still work on regular hd2, and most of them have two flavours, regular and tmous, with the difference being the use of sd card EXT.
On the flip side, there are loads of roms that say specifically NOT for tmous (winmo roms that don't have a tmous base)
And thats not counting the stock roms, there are dozens of stock roms, all the languages and networks and regions and such like, tmous cant touch any of them, except the three or four tmous specific ones, instant death if it tries.
summary, regular hd2 can use every radio and 99.5% of all roms, tmous can use 50% of radios, risks instant death if it touches the wrong radio, and can only use around 60% of the roms.
victory to the regular hd2 in my eyes hehe, not worth the hassle just for an extra 512 meg rom.

Hey Samsamuel I found your post very informative. I am not trying to say I do not believe you cause I very much do. But I was wondering if this is information you have learned through just your personal research and use of the HD2 or if you could post a link or links to some of this information. Cause I would really like to learn more about it being I have a TMOUS HD2. Any futher info on this would be highly appreciated.

Its all just from reading and being a natural tinkerer, and a keen interest in helping problem solve, plus reading everything, whether it seems like an interesting topic or not. come every day for a month, and read all the new threads, and you'll see there are about 10 main problems, and each time you answer it it gets a little more ingrained hehe,.
If i were to post any link it wouldnt be any particular thread it would be
http://www.google.com/advanced_search?q=+site:http://forum.xda-developers.com&hl=en&lr=&as_qdr=all
start your search with hd2 and you wont go far wrong.
The info is all here, most of it several dozen times over,, its just a bit like looking for a needle in a needle-stack.

[Q] Experienced flasher but new to HD2 - need advice

A little background: I have been flashing other phones for over a year with no problems, so I normally can find my way around these things. The HD2, however, has proven a bit more confusing because of the tmous (mine) Vs international version. I have been doing a lot of research so far. Each day, however, I find reports of bricking (some unfounded, some terrifyingly real), I need some advice from my more seasoned fellow XDers.
Here is my scenario: I bought a T-Mo (US) HD2 to use as a tablet, mainly since I have a Sprint TP2 I intend to continue to use for the moment. This means that I am only using WIFI data. I have been using Android SD ROMs successfully, and they run smoothly. This is the extent of my progress so far.
Here is what I want to do: Flash WP7 and continue to use Android on SD. Should WP7 totally suck, I want to try NAND versions of Android not available on SD.
My concern is that some tools are appropriate for my handset, some are not. Of the former, some are not appropriate for WP7, some are not. I am not too worried about bricking the device since I'm not flashing WinMo ROMs on this one. However, I don't know if I HAVE to flash a radio as prescribed in many threads, since I'm only using WIFI. I have read about issues flashing wrong radios and screwing up a perfectly good device. Lastly, has anyone heard of a ROM for an HD2-as-tablet? I'm sure I'm not the only one needing this!
Your advice would be most appreciated. Thanks in advance!
P.S. I am familiar with the super-awesome noob guide http://forum.xda-developers.com/showthread.php?t=653614, and found it very helpful. I'm just making sure I know what I need to know before I take the plunge.

TMOUS HD2 takes XX.XX.50 radios, Flashing a XX.XX.51 is a sure way to brick. however a brick does not mean the phone is trash there are a few guys on Ebay that can fix it using JTAG pretty cheap. Read the stickeys they are how I got started. The radio is the big thing though other than that this phone is really forgiving. especially after loading HSPL and MAGLDR!

As above the wrong radio is the only real sure fire danger, which boils down to "never ever flash any stock rom except tmous stock roms" (or 51 radios, or 2.04.50 and 2.05.50 which also act like 51 radios.)
Its easy to avoid,since all tmous phones naturally come with a ..50.. radio that works with magldr and such, so no,there is no need for you to flash a radio, you can skip that step.

Thank you I was not aware of those two radios, I immediately went to my little archive I have built up over time to make sure I didn't have those since I have been going back through my radios lately to see if I can get better reception in my house. Luckily those weren't in there.

you should also probably avoid 2.06.50 too, , without digging through the threads im not sure ive got it right with 2.4 and 2.5, it may be 2.5 and 2.6, since they are the two that come with the very first tmous test roms ( the first two links in the 'tmous stock and test roms' thread)
The first tmous shipped phones came with radio 2.08.50 so i see no reason why anyone would wanna go lower than that.

Thanks to you both. I think I will give NAND a try this week. Now I feel more confident I will not cause more headache than it's worth.
I really like the HD2!

[Q] Which version of HD2 shall I go for

Hi Friends I am going to purchase a used HTC HD2 so i need your help in choosing as in which version shall i buy the old htc hd2 or the tmobile version please help. I am from India

t-mobile version is the best

T-mobile offers 1GB of NAND (which is excellent !!!) .. but you need to be careful of what radio you flash, it is easily bricked by flashing an incorrect radio
So, yes, go for the T-mobile. (but be careful)

TMOUS ..............

No doubt HD2 T-Mous .... I own HD2 WWE and T-mous ...

Buy original T-mobile I had it from last 2 years no problem. Try to get original with windows mobile 6.5 unlocked. Do not be fascinated by Android or Windows 7 in HD2 as preinstalled because you can install them yourself when you get the phone. And you never know preinstalled android or W7 might have some bugs or tweaks required. good luck. And congrats because you are about to buy the most powerful phone in the world.

Thank you very very much
Thank you Thank you Thank you I am going to get the tmobile version in a few days however anyways to check if its a genuine tmobile any signs i can look for ?
Also I really appreciate you guys making an effort to reply as this was my first post in the hd2 world, and I am going to sell a 8 months old galaxy ace for the HD2 and your reviews have just concreted my decision hence cheers HD2 here I come

Hey.. b carefull!!
I appreciate your choice to buy HTC HD2, its amazing set
But be careful, some of the HTC HD2 sets have unresolvable hardware issue, that is they get overheated followed by freeze on mild to moderate usage, they work fine until their temp rises to 36~37 C, suddenly they freeze like that nothing will work, neither hardware keys, nor screen will respond, no other way to except pull out battery, wen u ll restart phone, it will vibrate 7 times and again will freeze, only way to let phone work again is to let it cool down for 5,7 minutes
So this sort of mobile set will be handicap especially in temperate climate of India, so i recommend you that when you examine your mobile, do anything like wifi downloading, net browsing, mobile call, video playback for at least 15, 20 mins and observe if this phenomena happen, if you find so, don't purchase such mobile set
Regards

Thanks a ton

Hey thanks a ton for the effort bro but I wonder is this issue there in all the HD2's or just some because the one that I am getting is the T-mobile one and am not sure i ll get to test the fone for such a long time as it is used so if you can suggest a shorter way to test the phone or any indications i can look for it would be a great help so please advise bro

Thanks a ton

Can anyone give the reason to go for T mobile HD2 other than 1 GB Rom in it..
I am getting HD2 EU version and was just curious why not other HD2
Will 1GB Nand makes any difference in flashing or any other activities or general working of the phone as such? .. obviously 1GB>512MB so ppl will obviously go for it, but just want to know will it make any difference

Bigger ROM space is very very useful & touchscreen on TMOUS is the revision 300 type.
If you can not get TMOUS then a 512mb version will do ok ...

I am getting 512 HD2 EU version only.. Can you tell the major difference btw 1024 vs 512 HD2...
Also what is this revision 300 type.. how is it different from 512 HD2 ?
Just curious..

revision screen has better build & not same supplier as 295 solder type & plug clip connector between LCD & digi.
You will find some 512 models have later type 300 screen & you can check this in bootloader.
As for RAM you will wish you had more but it is not a big problem.

Honestly? The end user will probably not notice the difference between the two The only thing that matters is how well the previous owner has taken care of the device!
If you still have doubts then ask yourself 2 things:
1. Are you going to be cooking your own ROMs?
2. Are you going to repair the phone yourself if it breaks?
If you can answer no to those questions then the best choice for you is the phone in the best condition - simple as that!
If you want to know the differences then the US version has a different digitizer that is more easy to chance if it breaks and then of course 1024 mb of NAND memory The latter might be a tempting point to choose the TMUS over the EU version but again you have to ask yourself if you are going to use the extra memory? Dont you use your memorycard? The only thing that comes to mind for me personally is that of bad sectors The more NAND you have the more bad sectors you can have but that is a small problem only... Go for the phone that is in best condition - period!

i'm surprised no one has mentioned the RADIO differences between the EU n TMOUS models.
my understanding is that if you require using 3G data, then the EU model is more friendly/compatible to the bands/frequencies used in most regions of the globe. the bands/frequencies supported by the TMOUS for 3G r more friendly with the TMOUS network.
someone please correct me if the above factor is incorrect!

Yep, that's what I had heard as well. Plus, I have the international version and can't connect to T-Mo's 3g.

TMobile 3G Network radio frequency - HSDPA 1700 / 2100
Other International 3G Network radio frequency - HSDPA 900 / 2100
One should have problem only with upload in Tmobile 3G frequency if he/she uses international version.. Am i right here?
Also is there any possibility that NAND roms size goes above 512 MB ? in that case how the international version handles it..

Radio difference is not a big issue, TMOUS works on GSM/Edge worldwide & 3G has worked fine for me in UK/Germany/Spain/Hong Kong/Singapore/Thailand on various networks ...
Good condition HD2 is most critical issue as posted above, I bought a TMOUS as cheap here new & come with 16gb SD plus 1GB RAM is a slight plus & they have the better screen as standard & later built units also have revision mainboard.

an wwe/eu hd2 does all the job that a tmous hd2 can !!
its just the rom difference ie 512mb vs the 1024mb in tmous !!
u'll mainly need the extra rom size while flashing the sense roms !!
sense roms are usually bigger is size and u'll require an ext3/4 partition on sd card for processing the dalvik cache !!
tmous hd2 doesnt require the ext3/4 partition as the extra 512mb is available on it !!
cyanogenmod, miui, wp7, wp7.5 and other os's !! work fine on both models !!
here is a comparison of both the devices !!
http://www.gsmarena.com/compare.php3?idPhone1=2957&idPhone2=3228
you'll just find the difference in the extra nand memory !!
and i think ur from mumbai so device will be used in india !
in india, 2G bands :900 1800 and 3G : 2100
are the respective network frequencies !!
so both devices will have full network support !!
good luck !!
choose wisely ! !!
