whats the whole point? - HD2 General

whats the whole point of FLASH. i want to do that to my phone but what will it do to the phone. can someone explain to me about FLASH.

Are you talking about flashing a ROM? If so the point is to get the newest or most stable build of WinMo.
Go to the ROM section and start reading the stickies. If you have a T-Mob HD2 you will want to pay particular attention to what ROM you do flash. There are two versions of the HD2, the European version on the T-Mobile version. The T-Mob version has a full gig of internal memory and a 1 gig processor while the European version only has 512 of memory and a smaller processor. If you make the mistake of flashing the wrong ROM onto the wrong phone you have an expensive paper weight.

yeah im talking about flashing rom. does this help the phone on working fast?

yes it does.

Sorry to correct you, but the Tmous has also 576MB RAM instead of 1024MB RAM, the European version does have 448MB RAM default, but after flashing a Tmous radio the ram can be unlocked so i has also 576MB RAM. I think you are meaning ROM instead of RAM
For me it's the RAM / Random Access Memory that counts since it's the memory you need to use in operation in contrary to ROM / Read Only Memory which is only needed to store your OS/Bootloader etc.
And cpu wise they got the same Qualcomm Snapdragon 8250B chipset/cpu running @ 1Ghz.
Ow and TS, if you are asking yourself what a FLASH is ? please don't try it if you got zero knowledge/understanding/informing yourself about flashing (be it pc,psp,hd2 etc.) that won't be such a good idea

Take a look at these threads:
Flashing a ROM (International HD2)
Flashing a ROM (TMOUS HD2)
Flashing a new Radio ROM
Complete HD2 guide for flashing (Video's included)
It's a lot to go over, but if you are going to flash your device I highly recommend you know what you are doing. A mistake can mean a very expensive paperweight.

To answer you question on the "whole point" thing..
There are several reasons one might want to flash their device.
I flashed hspl2 at first because I didn't like T-Mobil's lame pink pre-bootscreen. Then more recently I flashed a new Radio ROM.
Many (perhaps most) people flash "cooked" ROMs built by other members of xda (or themselves) which include their favorite apps, tweaks, themes, lockscreens, etc. already built into the ROM. Custom ROM's can also include updates to the Winmo OS.
Another reason is to change the Radio. The Radio ROM (not the FM radio) is the software that controls how your device handles data and phone connections.
Many people, including myself, flash a different Radio. Personally, I have found that my battery life, signal, and data connections have dramatically improved after doing this. You might also need to flash a new radio if you are going to try out the new(ish) android port.

Ya sorry for the mistakes. Thought for some reason the Euro version had a smaller proc as well. As for the RAM-ROM thing ya just wasn't thinking as I typed.

thanks for the information guys. i have alot of reading to do. so u guys recommand for me to flash after i read the information???

Well what ROM you want to flash solely depends on what your wants/needs are. I personally prefer a clean 6.5.5 build (finger friendly/start buttons on bottom) and my current ROM is Cloudy 1.5
You will first need to flash HSPL3 before attempting to flash anything else. This will protect you from bricking your phone from a bad flash and also enables you to flash your phone from SD Card instead of USB cable and PC etc.
Once you have chosen your rom just stick the nbh file (rename to LEOIMG.nbh) onto root of SD and boot into loader.
Read all the needed info before attempting anything.

where should I do!

I see slot of people flashing their phones but I dont see why.what are the perks of flashing and would it void my warranty with t mobile
The purpose of flashing is so you can get new roms that are created by developers which mostly run better than the stock roms. Yes you do void your warranty if you have a HSPL (Hard SPL) but you can return it to stock SPL if you need to use the warranty. It will act like it has never been there.
Its up to you what you want to do.
hnmmm i see. is there something that other roms offer that others don't?
Yes, the operate without all the fail that that stock rom is. Quicker, Smoother, and just more awesome. Try kumars rom out. its good stuff!!!
hmmm ok i meant app and widget/feature wise

Yes, tons. Just imagine everything you've added onto your phone with cabs would already be placed on the phone from the start. Having them already "cooked" in keeps the phone from lagging and makes it mush smoother. I had a lot of lag and freezing problems with the stock t mobile rom but since switching to Energy roms I haven't had any issues. For a list of apps and programs already cooked in just check out the official rom thread of the rom your eying.
i don't thinkid be able to cuz I couldn't really understand any of the tutorials on how too doo it sad day for me
does anyone wanna help me out here or is it just too much to explain. I'm just worried about bricking my phone
What's to explain.
Go and get the HSPL for your phone-put phone into active sync with computer-run HSPL.
Download a rom for the phone-load the file LEOIMG onto the main directory of the memory card-put phone into bootloader-ROM loads-done.
That's it.
but what if i need to hard reset or something and who can give me a list of roms that are compatible i don't understand how to find them
There is a thread stickied on the top if this section listing T-Mobile compatible roms. If it says T-Mobile,T-Mous, T-Mo etc, or 1024 leo it is compatible. The thing is T-Mobile hd2's hsve 1024 mb of flash memory while the Euro hd2 has 512 mb. If you flash a 512 rom you will have a brick. There are some really good threads stickied about flashing roms, tweaks and such. Read them a few times to get an idea of terms and procedures.
BTW... YOU and ONLY YOU are responsible if you brick your phone.
http://forum.xda-developers.com/showthread.php?t=653114
List of compatible roms.
yes i agree man which is why i wanna get all the details about my phone cuz i chose to flash it. i shall look over it. thanks much guys. would anyone be willing totteach me various things or point me to such places where i can learn to make a theme for myself or possibly make one for me?
Uhmm compatible roms..........Maybe in the T-Mobile section I linked to the one that says "T-Mobile USA HD2 ROM Development"? Granted there are other ROMs in the Standard Leo section as well as other site out on the net but you have to sift through to be sure they are compatible.
anyway what if i need to hard reset will it install my stock tmo rom or will it install custom rom again.
It would reinstall the ROM that you have loaded.
ok a few more questions and I'm done. will tmobile still notify me of updates and where can i find the stock roms in case i need to warranty my phone
Have you even opened the ROM development section? If you did you would have seen the first sticky is all the different stock ROM's that are around. As for updates from T-Mobile yes you will still receive messages from T-Mobile if they put out an update. If you want to load an update you can. If you ever have issues and need warranty work yes you can flash back to a stock ROM and stock HSPL.
haven't cuz it takes forever to load cuz i only have internet on my phone. sorry
you do realize that you need an actual computer to flash your phone right? You will have an amazing adventure cracking your phone with no internet access on an actual computer. Its not impossible but good luck..
This thread seems to have :facepalms: and written all over it.
Read up and read more. Then when you think you have an idea what to do, read again!

Some questions about cooked roms from a scardie cat

Morning all,
I've had my Leo for about 6 weeks now and out of curiousity i decided that before I went to bed tonight I would see what the score with the 576MB Ram hack/fix/tweak was. To be honest I am very impressed and disappointed at the same time. The reason for my impressed-ness was my phone actually does have 576mb of ram and not 448mb!! "SWEET!!!!!", I exclaimed, but while researching the topic it's been made very clear (hence my disappointment) i need a tmous 202 based rom (I have a question about rom version numbers themselves I will come back to at the end). I have a european HD2 on O2-UK and my first question is this:
Will a tmous 202 based rom brick my Leo?
It was also made clear that i need a radio version of 2.08.50.x was needed.
**ANSWERED** I have 2.10.50.19_2. Will that enable the extra RAM? I found out, thanks to nrg, that any radio versioned 2.xx.50.x_x will unlock the extra ram
My research also showed that hspl2 is most likely required. So which version of hspl2 do i need? I have already flashed hspl to my device as you will see from my sig so that is no biggy. I just want to check version numbers.
And, finally, going back to the rom version numbers. I understand that I have rom version 1.66.blah and that there are versions before and after mine spanning from 1.43 to 2.02 (maybe higher) but I don't understand which of these has WM 6.5 and which has WM 6.5.3, 6.5.5 or whatever. I've been looking like mad trying to find some sort of table but I'm lucking out and a pointer would be greatfully received . I ask because i am aware that in 6.5.5 the taskbar has moved from the top of the screen to the bottom and there are also several other differences between the versions.
So i think that just about covers all my questions for now on this topic. Massive thanks to everyone who can provide useful and helpful answers and just a little less thanks to everyone else
I just thought i'd give this a bump becuase i noticed it got moved. I also came to settle on energy rom standard sense 23569 but i can't seem to find a link for the june 6th version. Although with the comments i'm seeing about the new touch driver that nrg included the may 25th version my be the way to go.
I'm still looking for answers on the TMOUS 202 based rom questions and the hspl2 question. I'm not entirely sure what the answer to those questions is. From my reading it would appear that the TMOUS 202 rom would probably brick my device but i can't confirm it but it seems hspl2 would be ok. Does anyone have any confirmation on these?
And, lastly, does anyone know where i can find some clarification on which build numbers or rom version correspond to which WM 6.5 tree? this one is bugging me because i'm expected to make and informed choice and not knowing exactly what i'm flashing on my device isn't helping
hey mate, I am not sure as to the correct answers to your questions, but I thought I may aswell tell you about how I did with flashing my unbranded UK rom with a 576mb rom.
I decided top load a 576mb rom when i loaded a custom one since when i chose to load a new custom rom they had worked out most of the issues with 576mb ram (noise on phone calls and instability and stuff)
I had a good search and I was most impressed with this rom:
http://forum.xda-developers.com/showthread.php?t=653994
(sadly this rom has been discontinued)
So i set up my device, I installed the latest hspl which was version 2.08 at the time
I downloaded the rom, I followed this guide:
http://forum.xda-developers.com/showthread.php?t=609477
I did the task 29 first
then proceeded to start loading the rom
it started to install, then hung at around 25% I was quite distraught at the time, I had only had the device for about 1 week and bricking it so quickly really worried me.
after about 20 minutes of sitting there watching it I decided to pull the plug.
I restarted the device and of course it just hung on the htc logo
I restarted it again and got into the hspl bootloader (i breathed a sigh of relief knowing i could at least get the official radio back on it and then send it back to htc if something was wrong)
I tried to install the rom again however, and it hung at the same point. I was slightly confused now and decided to look at my setup.
My pc is a long way from my desk so I use a lot of usb extenders and hubs. Now I had seen advice not to flash it through a hub, so i was using an extension wire to make the htc cable long enough to get to the phone.
i decided to try and flash it without the extension wire.
It worked, it flashed in about 6 minutes or so, rebooted, and worked fine.
and now to this day I stil have that rom on it and I havent looked back, its been the best phone user experience I have ever had.
I also have the full 576mb of ram available now and it is working fine.
I hope this to be a reassuring post more than a scare story. The truth is that once you have hspl on the device it is actually very hard too brick it (similar too PSP's if you ever worked with custom firmwares on them and their equivalent bootloaders)
So my advice would be to go for it, follow the guides available and enjoy a new 576mb ram device
it's been made very clear (hence my disappointment) i need a tmous 202 based rom

not specifically 2.02 rom, any tmous rom will unlock (when flashed with a correct radio, more in a sec). The latest stock is 2.13
however that doesnt mean you have to flash a tmous stock rom, it just means the custom rom you flash must have used a tmous rom as its base. (Any rom that advertises itself as 576 enabled uses tmous as a base)
It was also made clear that i need a radio version of 2.08.50.x was needed.

Any radio with ..50.. and not ..51.. in the version number, when used with a 2.x based rom (cooked or stock) should work to unlock the RAM.
If you flash a 576 enabled ROM and your radio is still a ..51.. the phone wont boot, or may only boot once, then hang at grey screen, until you enter bootloader and flash a ..50.. radio.
My research also showed that hspl2 is most likely required. So which version of hspl2 do i need?
Click to expand...
Click to collapse
HSPL2 is not required if you already have HSPL installed, all the roms will work quite happily with the HSPL you already have. However HSPL2 lets you choose more than just 1.42.HSPL, so you can match the spl to the rom version. (Or do as i did, install 2.08.HSPL and leave it at that, regardless of rom.)
No proof that having the correct spl or a higher version spl makes any difference, but it can't hurt, right?
I understand that I have rom version 1.66.blah and that there are versions before and after mine spanning from 1.43 to 2.02 (maybe higher) but I don't understand which of these has WM 6.5 and which has WM 6.5.3, 6.5.5

All stock roms, , , , ALL stock roms, , are 6.5
You can tell by the build number, the 5 digit number in chefs rom thread titles, but i dont really know.
There are loads of different builds, i 'think' builds 21xxx are 6.5 whilst 23xxx are 6.5.3, but 6.5.5 is also 23xxx, or maybe 28xxx, hehe. Sorry, you'll need to look that up.
Oh, and regarding the unlocked ram, when you are loking to see if it is unlocked, if you view the systems available memory, it will show 448 (128 taken by graphics card), you should look in the settings - about phone - hardware info screen.
thanks sam you cleared some things up for me aswell as the op i dare say.
Thanks Sam. The radio thing i figured out thanks to something i saw in the rom dev board and because i was trying to get better signal for when i'm at a mates house down the road i flashed 2.10.50.19_2 a while ago so i don't need to do anymore with that but i think i will just blast hspl 2.08 on tomorrow.
I do have one question regards version numbers. From what you have said my understanding is that all the stock roms are 6.5 and not 6.5.x. I've also deduced from what you said about the build numbers (with the help of some brief research) that 6.5.3 has build numbers in the low end of the 23000 range possibly 233xx?) and 6.5.5 has build numbers in the 235xx range.
Once i do flash my phone i'm not going to be that concerned about checking if it worked or not. I spent 4 hours reading every post in the original thread on the subject and i'm convinced that as long as i use the right radio and the right rom everything will be fine. I'm just not looking forward to transfering all the data on my sd card back and forth

New User with HD2

Hi, I recently bought a T-mobile HD2, the unit isn't unlocked yet but I plan to unlock it and use it with AT&T, anyways I'm interested in running Android on the device. Would updating the HD2 from the HTC website which I believe is the official update website prohibit me in anyway from locking out Android or do anything negative in terms of customization of the HD2 unit?
I am running the updated rom 2.13 I am on t-mobile though and I am able to use android all day but once I restart it reverts back to WM. So I am not sure if this helps you...I was able to get everything running but the calls sounded robotic. I read I needed to flash to a new rom.

Well first, if you have the T-Mobile version of the phone, you do NOT want to use an update from the HTC site, that's for the euro version of the phone. The upgraded stock rom that you can use is available on T-Mobile's support page for the HD2.
Now, flashing to the correct updated ROM will not prevent you from doing anything...you'll still be able to unlock it later, you can still run Android, and you can still do any customizations you want. It's just a newer version of the stock ROM that originally came on the phone.
Hey, thanks so much guys, I'll search for the T-mobile page. I'm glad you guys caught it before I bricked me phone.
BTW, I read that you the T-Mobile Version of the HD2 doesnt use radios. What exactly are radios? I know they mean like firmware versions but what is the term. Also, do you guys recommend flashing a different WM rom or just keep the stock one? I tried to read about Android on the HD2 but I need some user advice. Is Android now stable enough for everyday use on the HD2? Also, could you use applications on the HD2 Android Rom? Will they work as they should? Lastly, why didn't the developers develop a Android rom that you could flash so you didn't have to reboot into it after every Hard Reset?

The US HD2 certainly does use radios, it just uses different ones than the euro version...in fact, that's most of the reason the wrong ROM could brick your phone, because of radio incompatibility. As you said, the radios you see referred to here are the firmware packages used to control the hardware radios in the phone (voice, 3G/EDGE, GPS, WiFi, BT). When you flash a different radio, you're applying a different set of settings to the way all that functions.

That's generally completely a matter of personal opinion, some people will tell you that using a custom ROM is so critical that if you don't your grandchildren will walk funny, etc....whereas I am doing just fine running the stock ROM and just manually tweaking and hacking it to my liking, part by part. However, if you're going to be running Android on it, there's evidence that having a custom ROM vs the stock will help with some of the known problems with the Android ports that are available.

There's several builds available, and all of the current ones are remarkably stable compared to the first attempts. But, I believe that that there's still not any that are absolutely 100% fully-functional...each has some minor drawback or caveat, like BT or 3G or the camera not working right, but usually that's the only issue(s). Also, it's been a couple of days since I checked on those, so they may have come even farther since then. One common drawback to all of them though is the heaaavvvy battery drain...but this is also being addressed as quickly as possible. And yes, in every build the apps and marketplace seem to be working just as they would on any factory android install.

That seems to have become the final frontier for Android on the HD2...the release of a fully stand-alone ROM. Trust me, they are working on that, there's tons of members here drooling and waiting for that exact thing. It requires a completely different method of loading Android into memory, so there's a lot more kinks to work out

Wow, thank you so much sirphunkee, you sir are a scholar with your detailed response. Anyways, I apologize but I am intrigued by your response and more questions evolve. Once my HD2 comes I assume it will have a older ROM version and a official T-Mobile Update will be available for me. Now, I'm just wondering would I need to worry about what radios I need or will that be taken care of for me.
Also, I'm still a little confused on the whole radio aspect. For example, in this picture located here:
hxxp://support.t-mobile.com/doc/images/tm54430/tm54430_06.gif
The image version is different one is 2.10.531.1 and the other 2.13.531.1. Are these the radio versions or is this like the ROM version. If so how do I find out what my Hd2s radio is? I mean before I flash a rom how do I find out the radio it contains? For example on your HD2, sirphunkee, in your signature, you have:
ROM: 2.10.531.1 (82076) WWE/5.2.21889 (Stock 6.5)
Sense: 2.5.2012
Radio: 2.08.50.08_2
So I assume that you don't have the latest stock ROM right? Also, what does the WWE mean in your ROM version. Would you recommend me updating my HD2 to the latest stock ROM or not?
Also, I read before you flash a phone you need to install HSPL3 on the phone. This is what I'm told is a bootloader. But then Im also told that usually this bootloader is paired with official or leaked roms so that each SPL matches the ROM, so if I need to flash a HSPL3 on my HD2 before I flash a custom ROM do I need to redo it everytime? I mean the HSPL3 is supposedly hard bootloader that survives a hard reset so it won't be wiped from the device until I overwrite it so does that mean I need reflash it everytime I get a new rom so it matches the ROM?
Anyways, sirphunkee, you mention tweaking the stock ROM, would you recommend BSB tweaks or something else because I read about it and users have discovered that they lose some functions after tweaking their phones. Also would I need to install this if I just plan to tweak the original/stock rom?
Furthermore, is Android on the HD2 currently run over/on top of the WM OS so could that be the cause of the heavy battery drain? Also, is the Android OS on the HD2 booted through an exploit in the firmware of the HD2? If so could this be patched? Just a personal opinion of everyone here do you believe that Android on the HD2 that is flashed onto the HD2's NAND itself will be possible/could this final frontier be achieved?
Again I would like to sincerely thank you for everyone's patience with me, especially sirphunkee. Thank you.
No problem!

Most of the HD2's built or shipped in the past 2 months have the newer ROM on them, but even if yours doesn't then yes you can just go to the T-Mobile site and get the newer one.
Both of the stock ROM's have the radio(s) included, so you don't have to worry about it if you just stay with one of those ROM's. If you flash a custom ROM it (usually) won't have a radio included, it'll just use whatever radio was already on your phone (i.e. whatever one came with the stock ROM originally). You can flash to different radio versions....ONLY ones that are clearly labeled as being compatible with the US HD2...doesn't matter if you're running a stock or custom ROM, but it does require HSPL first before a radio can be flashed.
Also, I'm still a little confused on the whole radio aspect. For example, in this picture located here:
hxxp://support.t-mobile.com/doc/images/tm54430/tm54430_06.gif

The original stock T-Mobile US ROM (yes, the one I'm running currently) is 2.10.531.1 ("2.10" for short), and the newer one that's been released is 2.13...so that pic you linked there just shows the stock upgrade utility about to upgrade a ROM to the new version (with an included radio).
You can tell what ROM/Radio is on your phone by reading the little text that appears on the bottom of the screen during bootup, and you can also access that info through a settings option once the phone is running.
"WWE" = "WorldWide English"....just means that I have an english-based ROM. Other languages are available by applying ROM's specifically built for that language, but I honestly don't even know if any exist for the T-Mobile HD2, I think they're only available for the euro model.
Since it's very easy to flash the upgraded stock ROM, if your phone comes with the older one I would just suggest running that for a few days and see if it gives you any headaches....if so, then just go ahead and flash to the newer one. There's a number of threads in this section that discuss the differences in the stock ROM's, and the advantages/disadvantages of each. Regardless of which stock ROM you have, the process to flash to a custom ROM is the same either way (HSPL, etc).
Also, I read before you flash a phone you need to install HSPL3 on the phone. This is what I'm told is a bootloader. But then Im also told that usually this bootloader is paired with official or leaked roms so that each SPL matches the ROM, so if I need to flash a HSPL3 on my HD2 before I flash a custom ROM do I need to redo it everytime?

HSPL is "permanent", in the sense that it remains on your phone until you manually flash a different HSPL (like flashing back to stock SPL should you need to return the phone for warranty reasons). Once you have HSPL (yes, a hard bootloader) on your phone (HSPL3 being the latest/best to use), you can flash all the different custom ROMs or radios that you want, without having to apply HSPL again.
Anyways, sirphunkee, you mention tweaking the stock ROM, would you recommend BSB tweaks or something else because I read about it and users have discovered that they lose some functions after tweaking their phones. Also would I need to install this if I just plan to tweak the original/stock rom?

There a bunch of different things you can to to tweak a stock ROM, or to futher tweak a custom one, and BsB is just a nice tight convenient collection of some of the more common ones. I use BsB and don't have any issues related to it, but I also skip a few of the settings in it ("tap time" for example) that have caused issues for other users. Besides BsB, I also use HD2Tweak, JWMD Icon Changer, CHT/CHTE, as well as a whole list of other stand-alone tweaks that come in the form of cab files, or manual registry hacks...some are related to performance or function, while some are strictly visual or style tweaks.
Furthermore, is Android on the HD2 currently run over/on top of the WM OS so could that be the cause of the heavy battery drain? Also, is the Android OS on the HD2 booted through an exploit in the firmware of the HD2? If so could this be patched? Just a personal opinion of everyone here do you believe that Android on the HD2 that is flashed onto the HD2's NAND itself will be possible/could this final frontier be achieved?

I originially thought the same (that Android ran in parallel with WM and that was causing the batt drain), but from what I read it actually shuts down WM when it runs, so I guess that isn't the cause of the drain...but honestly I haven't been able to keep up with all the finer details of the Android porting that's going on. And yes, a version of Androd that will load straight to NAND at bootup is the final hurdle I was talking about, and that's exactly what a number of dev's are trying very hard to make happen....I suspect that a breakthrough in that is right around the corner, but I'm no dev so take that with a grain of salt!
Hope that helps! It will be a lot easier once you have the unit in-hand and can play with it yourself. Also be sure to look over this thread (if you haven't already): http://forum.xda-developers.com/showthread.php?t=663845
Thank you again sirphunkee! Anyways I just got my hd2 and for the most part I like it. Though, I have a question, how can I backup my contacts so that after a new rom install I dont need to relink their facebook accounts again? Basically, I don't have the same names for my contacts, I only have first names so I have to redo it manually one by one and I want to use activesync to do it but it's telling me I need Outlook. Why do I need Outlook? Isn't that a stupid outdated email application? Also, how do you remove all the bloatware like blockbuster from the HD2? Is flashing a custom rom the only option?
Also, I noticed a problem that windows marketplace apps seem to not install. I try to install Skyfire and I see the progress bar and it goes to like 3/4 of the way and never goes past that.
An unrelated question I want to install HSPL3 I have a SPL 2.10.000 on my Stock 2.13 T-Mobile I'm wondering since in the instructions it tells me, that:
*YOU CAN NOW CHOOSE WHICH VERSION OF SPL OR HARDSPL YOU WANT TO FLASH TO YOUR PHONE*
*You can only select between SPL2.08.0000 or 2.08.HSPL. This is to avoid people with 1024LEO's installing an incompatable version and bricking their device*
What exactly am I suppose to pick? A SPL or HSPL? I mean I want to run Android but will this HSPL interfere with my stock ROM? Also, can someone give me like specific instructions on what I need to pick in the installer?
anyone have a idea? I'd like to experiment with android but i wanna make sure i have the right settings to i dontt have a brick in my hands after I'm done.

If you're just going to put android on the phone, you don't need to mess with H/SPL at all...you only need that if you're going to flash to a custom winmo ROM before putting Android on there.

Thanks for your reply once again sirphunkee, but it says in this thread that I need HSPL3 to get android to run stably.
http://forum.xda-developers.com/showthread.php?t=732380
Also, don't you need HSPL3 to flash a custom ROM in the first place as described here?

I think what that thread is saying is that having a custom ROM is what helps with the stability of Android, not just putting HSPL3 on there (unless that's buried in that thread somewhere that I missed...). But yes, putting a custom ROM on the phone would have the prerequisite of HSPL anyway.
I don't have a custom ROM or even HSPL on my HD2, and I'm currently using the Desire v5 build of Android on here. It seems to run very stable, but I haven't yet gotten a few things working on it (i.e. 3G)...I can't say if a custom ROM would make those things work, but I can say it doesn't ever crash or hang or seem to slow down at all.
I just wanted you to know that HSPL wasn't mandatory for you to be able to try out Android on your phone.
Ok thank you so much sirphunkee again. Anyways, I'm wondering if you know why my weather will not update now when I ask it to on a Wifi connection. I try to update it and just says that its a connection error. And also my windows marketplace app installs seem to stall on the 3/4 complete and they never finish. Could you perhaps help me with that?
Lastly, I was wondering would you be able to tell me if I wanted to put a custom ROM on my HD2 what setting do I need to put on my HD2 for a successful flash?
FIND THE "ANDROID ON HD2" THREAD everything is explained.

[Q] Is 1024leo (T-mobile) "backwards compatible" with 512leo (EU) roms?

The title says it all, I am in the market to buy an HD2 and plan on using NAND android and maybe even dual boot with WP7.
Currently, I have an open choice between the T-mobile and the EU version. 3G data is not a problem for me, nor is the extra 1.5mm in length.
If I do get the T-mobile version, which I am leaning towards, will it be able to run all 512's based roms or work only with those specified or custom made?
I am also fairly certain I won't be able to find an SD card more than class 4 or 6, so will the slow SD card be a major hiccup when using App2SD or Ext2SD?
Also, just to confirm; 1024leo's have their own radios... right?
Thanks a lot for answering my questions, and I did use search extensively but couldn't find anything specific to my question.
Not sure about which radio WP7 uses.
But i am running a DFT rom that is compatible for both the EU and TMOUS device.
Currently,many chef have been clear what their build is made for.if it isn't specifically stated,then most are compatible on both devices.
you can find roms that is customised for tmous only.
also,you might want to read up on flashing for the tmous device.its a bit different from the eu device.
oh yeah,jus so you know,tmous devices have a sim lock on them.if you plan to use other carriers,then u have to get it unlocked first.
Is the unlock easy? How much time will it take?
I guess the extra 512mb of ROM is worth the extra hassle... I wouldn't be missing out on anything I suppose.
Thanks
bump.......
You will be able to run only ROMS made to use for 512mb devices. And even after installing most ROMS you might run out of space on your phone to install apps. So you will have to use ROMs with APP2SD compatibility. If I would be there in your place. I would definitely get 1024 version.
Once sim unlocked, will i need to unlock it again after installing custom ROMs or nandroid for that matter...

Nope, you don't have to unlock it again....
Are you sure? Even after multiple flashes and SPL and radio flashes. I've been searching around, and people are mostly unsure about it.

Well I am mostly sure about it. Once you unlock your phone, you don't need to keep doing it again and again.
If you have a choice of a TMOUS version, go for it. double the rom size is worth all the hassle...if you got a friend living in USA and is in contract with TMOUSA, you can ask him/her to get you an unlock code from TMOUS CSR for free. or else, it's gonna be about 20-30 bucks to unlock it
guys you know the cyanogenmod 7 android 2.3 rom for HD2 is it compatible with the EU version of the HD2? I wannna try it but I don't really want to screw the phone lol
I am a noob so sry for the noob question

[Q] SD Card Vs Nand Install

I just purchased an HTC HD2; which came with a dual boot of Windows Mobile and Froyo on the SD card.
I wanted to install CM7; but I'm new to the whole process and I have heard various methods of installing it; either on the SD card, NAND, or RAM?
What are the pro's/con's of each? Which would you recommend?
Go with NAND and MAGLDR.
RAM builds are kinda obsolete now.
SD Card.. uses more battery and cannot mount the phone as USB mass storage.
Latest ROMs, tweaks etc are in NAND.
NAND hands down.

I would recommend trying multiple different ROMs on SD (e.g. CM7, MIUI, Sense 3.0, Sense 3.5 etc.) on SD, then, once you've selected a ROM, flash a similar NAND ROM.
Thanks guys, I appreciate it. I've heard some rumors that NAND has some issues so I wasn't sure.
Is NAND the ROM?
Since I will most likely do a NAND flash, this would be the best guide right? (http://forum.xda-developers.com/showthread.php?t=893948)
Also, the phone is currently SIM-Locked;I wont be getting the unlock code from the buyer for another day, would I still be able to flash the phone and THEN input the unlock code after without screwing up anything?

yeah, that one guide is great.
I would personally advise you to try out the clk versions, it acts more like a native android device. Also, with clk you will be able to use clockwork mod recovery, which makes things a lot easier.
I'm using AmeriCanAndroid, and I couldn't be happier about it.
But anyway, for sure go for the Nand version, that means that android will be installed as the native operation system, formatting the internal memory and getting rid of windows mobile. You won't need it anymore.
P.s. Just to make things clearer: nand is installing android on internal memory, clk and magldr are types of bootloaders to use and install nand android through.
Sent from my HD2 using my fingers.
I would recommend using a NAND based ROM over an SD. Uses less battery and is smoother running, unless you just have to have WM. And if an issue arises, a NAND based ROM is easy to back up or change out to a different ROM. On your question on unlocking your phone, the process is independent of whether your phone is on WM or Android. The procedure to unlock the phone is based on the IMEI number of the phone and uses hidden features on the phone independent of the OS on board.
Thanks guys. I just had a few more questions,
Is the guide that I posted compatible with a T-Mobile version hd2?
In terms of flashing, are there any big things to be careful about to avoid bricking your phone? (radio, etc?). Would there be any way to salvage a phone if something were to happen?

That's the guide I used to flash my T-Mobile US phone. So it should work for you as well. If something did happen to your phone, you can always flash back to WM. Follow the guide, you shouldn't find that you will brick your phone. As long as you don't flash the wrong radio. US phones use the 2.xx.50.xx versions and EU use the 2.xx.51.xx versions of radio. If you search for the radio thread, it will fully explain this and have the correct/latest radios available for download. Just don't mix them up and you won't brick your phone. Latest radio version for US phones is already in the guide that you posted.

Actually, I would recommend this guide. The guide you posted doesn't involve CWM and is thus pretty much useless for modern ROMs.
And the Radio version should be in phone software info (if I remember correctly) under settings.
I think it doesn't matter as far as your sd card is fast enough! I am buying new Tmous HD2 since i don't have to make sd ext for sense Roms and they took 1.5 hours to install on my wwe HD2! Big advantage of sd build comes when you dual boot.
Thanks for all the advice guys. I'm a bit caught up with work so I wont try flashing it till this weekend, thanks again.

Go under Settings then About Phone and you should see a line called Baseband Version and should tell you after the underscore what radio you are using. Mine shows 2.15.50.14 which is the latest for a T-Mobile US phone.
