how to downgrade from 2.2 to 2.1 - EVO 4G General

I need to downgrade to 2.1 or if i could to lower than 2.1 ., and install ruu older ROM if i could.,
there are some thread on how to do it., but with no links or files to download for the incredible ., I do not want to guess which file to download and where to find it and if its the right file .
I can go to few of the RUU , but pretty much the ones with 3.30 .70 .. and i think 29 ., if i need to try the older ruu like 147 651... the evo crashes ., so i think the only way to install these ROM is to downgrade to 2.1 .No?
so please if one knows of a way to do so ,advise me . or if you know of a link or tutorial for the evo with all files names ... etc would be great ., this way i dont have to guess and brick the phone .
any good feed back is appreciated ., sincerely

why do you want to downgrade? and you need to be rooted to do it btw.

Iam rooted .
well i need to install one of the old radios ., the i tried to intall the older radios but the phone would freeze and i have to end up reinstalling the supersonic ROM., like RUU 3.29 or higher.so i could not install the older radios ..,
I need to repair few locations of the meids and ive been scanning for weeks and cant find them. so i quit .i hope thid would be my last resort ,if i install older ROM with older radio i can fix it.
sincerely

what hardware are you on? i dont think the newer hardware can handle 2.1 cuz it was never built for it.

First off, I don't know if this is a troll post or not.
Second, I'm assuming if its not a troll post, you are ESL, or something. Your grammar and punctuation needs some... work.
However, what I'm reading is that your evo is crashing when you are flashing a rom. I've got to ask, did you wipe the data before trying to flash a rom? Its kind of important.
The android version (2.2, 2.1 ect.) is what android version the rom is built off of. To downgrade this, you simply need to find an older rom, and flash it. On top of that, you probably need to downgrade your recovery. The two recovery threads in the Android Development section have pretty much every every single version from 1.0 in their mirrors, so you should be fine there.
However, I haven't seen a 2.1 rom for the Evo, but I'm new to the scene.

I still got 2.1 Rom if u dos search for omj eclair on Google u can still find it. If u really want to downgraded try using the very first PC36IMG.zip from toastch rooting method it will downgrade for ya.
Sent from my PC36100 using XDA App

Good luck with the downgrade and stuff. I don't know what situations call for running radios that were around back when Eclair was out...

Shipped-roms.com? Ruu maybe all the way back to the launch rom...

people do crazy things, like eat at Arby's

when i try to install an older supersonic RUU ,for example 1.32.651.1 Radio 1.39.00.04.26., the process start ok then the phone progress bar goes from green to red vibrate few times and continues to just about the end ,then gives error on PC ..didnt complete ..etc.howeveer, when i try to boot EVO, no go i have to reinstall a new RUU like the 3.70...., and no i do not wipe info before i install the ROm,and have no idea how to do that ., i thought a new or old rom would do the wipe clean data etc.., so how would i need to go about doing this .?
again thank you all
and yes its a new EVO hardware version 0003

what's your hboot as of now?

This is what ^ means...all the RUUs...have at it.

the Hboot i have know is 2.10.0001., and have radio 2.15.00.07.28., thats because i installed RUU supersonic 3.29...., this is more or less as low as i can go and i cant install an earlier radio .or the phone will crash and i have to reinstall the RUU again., the phone is rooted with unrevoked but i didnt do the nandroid unlock., because cant get the sdk platform to work on my pc....etc
yes i know there are shipped roms ...etc ,but again i cant install whatever i want., the phone will crash ., the lowest i did from 3.70 to 3.29 , again i would want to install 132 .651 ..., but it wont install it.??, so thats why i think i need to downgrade to 2.1 ..etc ., if not what do i need to do please.
sincerely

ok then it might be because your phone is too new... still confused on why you want it. check for an old rom in rom manager and download old radios in calkulin's thread. try that.

yeah it wont take older roms or older radios ., would have been simple if it did ., so the answer is i cant .?
so i cant downgrade to 2.1 ?, even if bootloader is newer than older evo.?
well why i need to do it is a subject here they do not want us to talk about but oh well., when the phone was new never been activated had the MEID repaird on it., just downgraded to older rom and was easy indeed to zero out the digits ., few weeks went buy resetting the phone and doing 786 ., the meid digits changed to where HTC had them., and know been weeks trying to redo that ,I cant i mean weeks all day till night ., some meids wont pop ., but they are hidding ., so they say if i go older radio should be easy or easier .
thats all folks , any ideas sincerely

hah i have no idea how to mess with that stuff... good luck though.

so thats it you quit on me just like that ., you have no idea how i can downgrade radio or ruu to the 2.1 era .?,
iam willing to test
sincerely

i don't think you are rooted any longer. do you have s-off? if you ran the ruu without being fully rooted you most likely don't have root anymore but i may be wrong. i would say run unrevoked again and full unlock including the nand and you should be able to flash any radio and rom you want.

when i install an RUU ., and i try to do a recovery ., indeed it does not go to the menu it should ., it gives me the picture of the phone... and i think a circule of some sort., but i rooted it many times ., but no nand unlock ., again could not figure out how to run it.
so ok lets say what you say might work ,is there a an auto nand unlock here or there i can use .
sincerely

I think you really need to do a better job of searching instead of just asking question and having other people help.

I want the best of both worlds, I want to have the latest upgrade, but I don’t what the network provider

Hopefully this will alleviate some confusion about official/custom ROMs.
I'm not exactly sure how OTA updates work, but probably pretty similar to RUU's. An RUU is an executable that will flash several "ROMs" to your phone: Boot, Radio, Recovery, System and Data. It also appears to write to the SPL, but we don't care about SPL as much as we care about the Recovery ROM. Anyway, you run the RUU, it flashes all that to your phone as one big package, including overwriting our recovery ROM, and you lose root, probably forever. However, you can extract the ROM.zip from the RUU file and you see all the separate images that get written to your phone. With access to all the separate images, you can repackage them into an update.zip like we use to install custom ROMs.
You can turn an official ROM (from an RUU file) into a custom ROM in just a few minutes by manipulating a few files. (There are other threads dedicated on how to cook ROMs.)
So, if you think that there's some advantage to flashing the official RUU, there's not, because with a bit of reading and manipulating some files, you can flash your carrier's ROM without losing root/custom recovery.

Probably a few hours at most, depending on what time they release it.

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!

i've read lots of articles on this site. i suppose i'll need to instal another rom on my phone. i read a lot but i get little confused. i think first i have to instal HardSPL (forum.xda-developers.com/showthread.php?t=653614) second i have to flash a radio and i can instal a rom. and on this page (forum.xda-developers.com/showthread.php?t=591784) it says i don't need to flash a radio. which means that i just install hardspl and instal this rom... am i right?
can you guys help me what am i suppose to do... and which version of hardspl, radio and rom works well for me?
sory to ask lots of questions but i don't know enough about wm phones ( thanks for guides...
Hi, basic steps are
1. Backup your important data like contacts etc..
2. Its very IMPORTANT that you Flash HardSPL first before flashing any ROM (No worries,it only needs to be done once for you to enjoy subsequent custom ROMs). Version 2.08.HSPL is ok.
3. Browse the threads for a suitable "TMobile HD2 compatible ROM" or visit this link for comfirmed ROMs.
4. Perform a Hard reset after successfully flashing any of the ROMs
5. Enjoy!
i suggest u clear your schedule, get coffee, tea, drink(s) and visit This Link . It contains info and links to all the guides you can possibly need to push you and your device to a higher level. i wouldn't recommend trying android till you are very comfortable with flashing ROMs.
you dont need to worry about the radio just yet, because since you have a tmous phone, it already has a radio that will work with all tmous compatible roms anyway.
Well I'm gonna just say right now I'm not an expert or anything since I'm relatively new too. I'm just trying to help, I would however advise wait for a more experienced person to answer.
First, if you want to flash a ROM follow this guide for the TMOUS HD2's. It goes over how to do it, which ROMs are compatible and all that.
Yes, you do have to get HSPL (except I think there are methods when you don't, though that might just be for the international phones...). But to get HSPL you should probably use this. I don't know if it is the only thing that does it but it, from what I understand, is the most well known. It also keeps you from "bricking" your phone.
From what I understand the only time you have to flash a radio is if the ROM needs it, and the chefs will say if it needs a certain one or list ones that it works with on their ROM page. I think most of them support the radio that comes stock, though don't take my word for it. I would wait for someone else to confirm or re-explain this paragraph because I'm not completely for sure.
As for which ROM is right for you...well only you can answer that. They all are different and different ones have advantages over the others. You just gotta explore a little and see what looks nice. This is the list of ROMs that support the T-Mobile HD2 so stick to it. I don't know how up-to-date it is (meaning I don't know if there are any new ones or not) but stick to those, you can "brick" your phone otherwise.
I would however advise if you're new to WM phones to try out themes first. They are a lot safer and I don't think there is any chance of ruining your phone (the only reason I flashed mine is because I've done it with a different phone before and felt comfortable doing it). Don't do anything you are uncomfortable doing and understand all the risks that go into anything you do to your phone before you do them.
Sorry for the long post, just hope this helps a little.
Edit:
I just got double ninja'd

That's d spirit...You'll be amazed @ what the search function on XDA coughs up...Everything'll go well once u stick to d guides and TMobile compatibie ROMs & Radios.
i picked up this rom (forum.xda-developers.com/showthread.php?t=652649) but there is two options. 1) com5(c5) 2)com2(c2). i don't know what it means... and if want to install one of these roms do i have to flash a radio after installing hspl?
and what is the stock rom?
thanks again...
It looks like COM5 and COM2 are just different versions. COM5 offers more options it looks like though, but I'm not sure. Someone else can probably answer that a lot better than me. I am also unable to answer the radio question. Sorry.
As for stock ROM though, that is the ROM that came already on your HD2 when you got it.

I see u picked out Kumar's ROM...Click Here for a thread on the definitions and differences between COMs...And No, you won't need to flash a radio after installing HSPL or a custom ROM (Unless you are having problems connecting to your network in which case, u need 2 be careful 2 flash a radio known to work with Tmobile HD2).
Stock ROM is the original/default ROM which TMobile shipped with your device. Follow this guide and you can grab the stock ROM from here. The Stock ROM has to be re-flashed to your device if u ever have to return it to Tmobile as flashing a custom ROM voids your warranty. Grab useful links and watch video tutorials here.
Hope dis helps ya.

Is flashing a custom rom a good deal ?

Hey there,
im pretty happy with my phone, but sometime i feel like its some kinda bad to get apps for evey setting that htc did not provide in 2.2 (2.2.1 not available to me yet). Although i think enough "****" is running systemwise that noone needs.
So flashing to a custom rom seems to be an pretty easy thing if you
do it carefully and check all potential failure actions.
Will custom roms make the phone faster ?
To all that flashed yet: Do you regret it or is it like the best thing you can do ?
Do i lose any important functions of my phone ? Are the roms stable and working good actually ?
Thanks !

Having been running Custom Roms since I had my HTC Magic, I would heartly recommend them to most users, It's all about what you want from your phone though. If you are unhappy with all the bloatware installed and dislike sense it's an ideal way to streamline functionality, your DHD will, in most cases , run smoother than stock and should have at least comparable battery life. Currently I am running CM7 which gives me a stable gingerbread based rom, with a decent custom rom there should be no loss of functionality (even the FM radio works these days).
Custom ROMs are by and large an excellent way to keep your phone up to date whilst taking advantage of new features.
There is a risk of introducing new issues, but the support you get is a million times better than you'd get from the manufacturer, and new updates are usually a couple of times a week rather than a couple of times a year.
The main risk, I find (at least from my Windows Mobile days) is that some ROM developers tend to let things run away from them a bit and end up sandwiching so many new features and launchers and eye candy etc that it ends up slowing the phone down more than the stock ROM did.
So far I've not seen anything like that on recent Android devices, but with older handsets like the Hero there are some custom ROMs that are noticably slower than stock.
As long as you realise that there is a performance limit on your handset that will eventually be breached, then you will have a happy experience with custom ROMs.
Sounds promising. Really.
Im just irritated with the instructions.
My Desire HD is yet rooted.
But there is nothing about S-OFF or Radio OFF mentioned.
I remember most instructions with S-OFF and then Rom Manager or something.
But in this case - Whats the "Wipe" ? Normally means all stuff gets removed ?
Im missing detailled information, especially how installing the rom (via app ?)
and which version i need of my desire hd and more :/
Is this the safest way to flash it ?
And waht the hell means "vendor = ace" ?
Which vendor i "got" ? Im irritated or maybe i translate things bad from eng into ger
ps: guess i got it. htc ace was/is the codename for the desire hd device.

In my experience, the easiest way to get ENG S-OFF and Radio S-OFF would be to use jkoljo's excelent tools for S-OFF and Radio S-OFF. Here's a guide to flashing a new radio after you have done Radio S-OFF.
In the Radio S-OFF topic, there's also a small guide for flashing a new rom. If you need a more detailed one, you can find one here.
The next step is to find the rom that suits you the most, for example Android Revolution HD or LeeDroid. Download the ROM you like the most, then follow the aforementioned guide to flash it.
When you go from one rom to another, it's always reccomended to do a full wipe (unless it's just a rom update, then you don't always have to do it). In this case, it means that all your data and settings will be lost, except for the stuff you have on your SD card. You can use your Google-account to back up your apps and contacts and stuff, so do that if you feel you need it.
Hope this helps.
Other handy tools for data backup before migrating to a new rom are MyBackup Pro and of course, Titanium Backup.
Don't forget that contacts, market apps, and wi-fi passwords are synced to your google account by default, so no need for huge app backup files unless you have several apks from other sources..
The guides about S-OFF and Radio flashing posted above are detailed and relatively easy for anyone willing to experiment.
Just make sure that you check the instructions carefully, and double-check whatever you type in adb. The few minutes of making sure you're following instructions to the letter can save you hours of un-needed trouble and aggravation..
Also take note, different custom ROMs often recommend specific radios for maximum compatibility. This can make a significant difference in battery and wireless performance, specially with power hungry devices such as ours.
And above all, try different roms, see what you like best. Running the bleeding edge in Android can be as fun as it can be frustrating, so try to find the best suit for your phone and you, and enjoy it
So alright - I think i got it:
1. Root Device (Visionary)
2. Radio S-Off (Tool)
3. Radio Off (Tool)
4. Download a Radio.img (How can i find out which works best with the crom i want ?)
5. Use radio tool and reboot
6. Find a suitable custom rom
7. install and voila - there we go
Some questions that came up:
- Whats the "best" radio out there ? Is this as important as picking a good C-Rom ?
- HTC Sync preinstalls only means that i got it on my PC already, right ?
- And can all of those steps (except root) kill my device (=brick) or am i safe at the moment when Radio S-OFF and Eng S-OFF worked properly ?
- Nowhere is something about the VERSION i need ? So will a Desire HD 2.1, 2.2, 2.2.1 and 2.3 work with all the STEPS ?
Which custom rom is the best for me ? How can i compare all roms out ?
I only heard bout Android Rev HD, LeedDroid and CYMOD.
I want speed and i want a nice User Interface (but i guess i can reach that with ADW.Launcher.EX or Launch-Pro no matter how the Rom looks ?)
Thanks guys for all the answers already !
Would be so thankful if you can finish this with me.
PS: If i "brick" my device is there 100% no chance to unbrick it ?
Was possible with psp 2000 e.g. after some months. think so with desire hd too ?
1. In most cases, the developer of any given rom will reccomend a spesific radio to use with his/hers rom (like with LeeDroid or ARHD). Usually I'd just go for that radio, but as with so many other things in life, your mileage with a spesific radio may vary. While one user might report good signal strength and battery with one radio, another user might say the complete opposite. Anyway, stick to the radio reccomended by the ROM developer. I think that's the safest to do.
2. I've not even used HTC Sync since I bought my Desire HD, and I don't see the need to use it.
3. You're never 100% safe, but in my experience, once you're past the ENG/Radio S-OFF and your new radio is flashed, it's usually smooth sailing from there. But always remember that **** can happen, and you might be unlucky, so if you're unsure of something, read up on the subject as many times as you need for you to feel comfortable doing it.
4. As for what rom is best, that's really up to you I think. I've stuck to ARHD, and I find it fantastic, but you might like LeeDroid or CM7 better. Just look at screen shots, and try to figure out which one is most suited for you. And as you said, with AWD or LauncherPro, and the right wallpaper, any ROM can look beautiful
5. If your device is bricked, I don't know of any method of getting it back to life. All I can think of is send it to HTC, claim that it's dead, and hope for the best.
I flashed my first ROM yesterday just (leedroid 2.2.2). I havent really had much of a chance to explore the real benefits of it, but im already delighted that i did it. Just by being able to add custom themes, fonts and skins to get the phone looking much brighter and colourful. Also nice playing with overclocking the processor.
Took a bit of work to downgrade the software to get root, then a few problems getting s-off etc, but in the end it was all a good learning experience. Certainly dont regret doing it, just sort of regret that i put it off for so long. Looking forward to much playing about with different ROMS and customising them.
Just make sure you read the threads on here about rooting very carefully. And also read very carefull the instructions that come with each ROM. Leedroid recommended a radio that works best with his ROM, so i flashed that. Dont know if others do the same as i havent got round to trying any others yet.
Am i right that only with Radio S-OFF i will be also able to install custom roms,
but NO new radio versions ? Is the problem the compability (with croms) or is there any other reason for new radios than better connection/battery ?
Which users are fine with only Radio S-OFF ?
As i can read, RSPOFF is safer than ENGSOFF.
Also: the question about the VERSION is really making me moving.
Hope someone can explain me, why nowhere is mentioned something about it.
I remember 2.2.1 cant be rooted and 2.3 - so is this the explaination
(cause you cant go over step 1) ? or whats the point ?

5. Use radio tool and reboot
6. Find a suitable custom rom
7. install and voila - there we go

Once you've done Radio S-OFF (not sure what your step 3 is - seems the same as 2) then I'd recommend installing ROM Manager from the Market and ensuring you have either ClockWorkMod 2.5.1.3 (up to Android 2.2) or 3.0.0.6 (android 2.3) installed. This then allows you do do all your Nandroid backups and System wipes that you will need to before you flash a new ROM.
- Whats the "best" radio out there ? Is this as important as picking a good C-Rom ?

As said, there is technically no "Best" radio - but the dev of a ROM will recommend a decent compatible ROM. You are welcome to try others but you may notice weaker signal or degraded battery life.
- HTC Sync preinstalls only means that i got it on my PC already, right ?

It's useful for getting the right drivers on your computer - but probably not much else!
- And can all of those steps (except root) kill my device (=brick) or am i safe at the moment when Radio S-OFF and Eng S-OFF worked properly ?

Not "Safe" but at least much more likely to be able to recover. You can still permanently damage it - but doing so would be pretty hard work!
- Nowhere is something about the VERSION i need ? So will a Desire HD 2.1, 2.2, 2.2.1 and 2.3 work with all the STEPS ?

Generally the steps are the same throughout...though you'd be hard-pressed to find a DHD ROM on 2.1!
Which custom rom is the best for me ? How can i compare all roms out ?
I only heard bout Android Rev HD, LeedDroid and CYMOD.
I want speed and i want a nice User Interface (but i guess i can reach that with ADW.Launcher.EX or Launch-Pro no matter how the Rom looks ?)

Read their respective threads and see what you like and don't like. That's what everyone else does. No ROM is "better" than the other.
PS: If i "brick" my device is there 100% no chance to unbrick it ?
Was possible with psp 2000 e.g. after some months. think so with desire hd too ?

Depends how badly bricked it is! (see above)
To add the misstying under 2. or 3.
I meant:
2. Radio S-oFF
3. ENG S-Off.
What is ENG S-OFF in some easy words doing other than Radio ?
As i understood - without ENG S-oFF i cant install custom radio images, right ?
Means: New Roms, but maybe not the best compatible radios ?
Also: When installed Clockwork i can backup everything ?
Means a NANDROID backup i guess ?
I thought when i want to get back, i just need this Ruu Rom and
Set all Tools to S-ON ? So this Nandroid backup, whats that ? "Ruu" is the original rom and the "nandroid backup" is the system-backup/firmware/original radio.img?
Im just ab it irritated with all the words like rom, radio, firmware :/
Im so thankful for all the answers yet.
Never expected such useful answers, most forums full of guys that link
to other threads and do not really care. so until now - great work !

Am i right that only with Radio S-OFF i will be also able to install custom roms,
but NO new radio versions ? Is the problem the compability (with croms) or is there any other reason for new radios than better connection/battery ?
Which users are fine with only Radio S-OFF ?
As i can read, RSPOFF is safer than ENGSOFF.
Also: the question about the VERSION is really making me moving.
Hope someone can explain me, why nowhere is mentioned something about it.
I remember 2.2.1 cant be rooted and 2.3 - so is this the explaination
(cause you cant go over step 1) ? or whats the point ?

ENG S-OFF will allow you to flash rom's, Radio s-OFF will allow you to flash radio's as well (ENG S-off fools h-boot into believing it has radio s-off)
Radio S-OFF will not be reverted by flashing a new h-boot unlike ENG S-OFF.
Different rom's suit different people, seen as you are going to loose all your data falshing a custom rom, i would recommend flashing a couple and having a play around (leedroid and Coredroid etc have sense if that rock's your boat, Cyanogenmod is closer to vanilla android) as everyone has a different preference.
The Versioning of ROM's is a bit of a grey area all ROM's are based on an android release 2.1, 2.2.1, or even 2.3 etc but many have features ported to them from other release i.e stuff from 2.3 or even 2.4 may be present in a 2.1 based ROM so look for a rom with the features you desire rather than relying on the base. But some ROM's require different instructions for flashing i.e Gingerbread ROM's require clockwork recovery version 3.x this is due to different file systems used, to be safe make sure to read the first couple of entries in the ROM thread in the development section before flashing as it will list any special requirements or steps that need taking prior to flashing.

Maybe im just reading it wrong, but do you mean that Radio S-OFF has all the features that ENG S-OFF brings PLUS the radio flash option ?
Then why all the instructions say, i need both (ENG and Radio) ?
Generelly, you recommend only ENG S-OFF or will the most good Custom Roms not work that good with the original radio version from htc ?
And Gingerbread Roms need Clockwork 3.X - But Clockwork 3.X needs Desire HD with 2.3, as i got told above.
And i cant upgrad to this by using HTC Updater. I guess, i have to manually upgrade my original Firmware then, right ?
Complete guide in my sig (check out the dev forums, lots of them out there)
Radio s-off and eng s-off are 2 different things and you need both if you want to be able to flash a rom.
And yes, I love my custom rom more than I will ever love stock. Why? because it looks like the stock one but it's lightning fast and drains less battery. Oh, and I have better reception

Gingerbread roms need 3.X, but you don't need Gingerbread to install it. I have CWM 3.0.0.6 but am on a FroYo ROM. All down to my own personal choice!
Also, yes. a Nandroid backup is an exact copy of your ROM (not your radio). So all apps, settings etc will be exactly the same when you restore it. You can't do this without a clockworkmod recovery.
ROM Manager interfaces with CWM and allows you better management of your backups and also gives you an easy way to upgrade your recovery without having to mess around in a terminal emulator or command window.
The relationship between Kernel, Radio (Baseband) and a custom ROM? So in theory, can you mix and match different version and combination, but there seems to be proven combination that works better, is that correct?
Base on what I am reading, they are can contribute to a faster, more stable, and a more battery efficient phone system.

Nice Guide. Has everything i need.
Why i need both ?
In case i dont need/want a new radio version and ONLY a new crom,
i dont need the Radio S-OFF. Cause you say i need both ? Why ?
Maybe gimme a short answer to that.
Will be thankful !

For flashing under windows that is, the instructions here, whilst a little more complicated cater for all OS'es

Installing Android on ROM 2.13.531.1 and Radio 2.10.50.26

Hi
I want to install Android on T Mobile Htc Hd2 having ROM 2.13.531.1 and Radio 2.10.50.26
So should i install Android build directly into the SDcard and it will work or i have to change Radio , ROM etc before installing Android .
Android booting off ur sd card should run with ur current WinMo ROM & if it doesn't then u can always flash another (there r really light builds out there), hweva u should upgrade ur radio to 2.15.50.(can't remember d last digits)....better compatibility issues.
Yeah if you want to run Android off SD just update your radio to 2.15.50.14. I remembered the last digits haha.
You need HSPL on your device to do that. Just look for 'HSPL4' (use search) and just download it from the thread and then boot to bootloader and flash it. Then flash the radio.

Well, there's always d risk of bricking your device and honestly i hold my breath most times while flashing (despite having flashed a lot of builds,only had 2 change radio once)....So u must understand d risk involved but i tell u, d dev guys put in a ton of work 2 give us dis options & i'm sure they might ave bricked say 1 or 2 devices during testing...but all's good
