How to i change to other ROM?

Currently using HTC HD 2 Andriod rom running on nand,
Assuming Ive installed andriod with clockwork recovery and etc, and I would like change my ROM to other versions, how can I do it?
Do I need to delete the current Andriod Rom? and how do i do it? thanks!

Go to Clockwork Recovery.
If your coming from another rom (Miui -> CM7, Sense -> Stock, or any of that matter), wipe cache recommended 3 times, advanced -> Dalvik Cache. When your coming from another rom, it's highly recommended to wipe data too.
If your coming from the same rom (CM7 -> CM7) and want to KEEP your data, then simply wiping cache and Dalvik cache is enough.
To flash a new rom, choose "apply zip from sd card" -> "choose zip from sd card" and simply select the .zip file.
You don't need to delete or anything, Clockwork should overwrite it and your cache should be cleared.

I always do a Nandroid backup using backup and restore in CWM and then do a full wipe of all the partitions data, system, boot, cache, and sd-ext. Then I go to advanced in CWM and woe my Delvik cache, then flash my ROM using install zip from sdcard. When my ROM is done I go to backup and restore and select advanced restore and restore my data and my cache from my Nandroid backup then boot my HD2. I never once have had a issue with any new ROM or my information and settings not being there. You do not want to restore boot or system cause boot is the kernel of your ROM and system is the ROM itself. So if you restored them you still havecthe same ROM.

check ROM thread / instructions, there are a lot of information.
sometimes you need to follow exactly as it says.

I recommend running a Task 29cand then reflashing MAGLDR and then flash CWM using USB Flasher in MAGLDR then flash your ROM using CWM. Make sure to reformat your SD card before booting up your Android. Easiest way of doing this is to stick your SD card in a adaptor and then into a digital camera then format it with the camera as this will take the funky format that WP7 does to it off. Then use a USB card reader to format it using Fat 32.

just flash android using instructions from your ROM thread.
cheers

Ha I figured I had given you way over kill instructions lol. Go to the link below and try the steps in this guide I just found in the HD2 Windows Phone 7 Q&A General section.

Nand Android not booting thru cwm Recovery

Hey,
I tried installing Android using cwm rec., everything goes well, but the android does not boot, it gets stuck on the booting screen, i tried several time, diff roms, still no results, can any one help me if im missing something? :S

make sure you are removing any leftover stuff from a previous rom on the SD card.
So in CWM, before you go to flash the rom, do a 'wipe data/factory reset' which should clear out the ext partition and the .androidsecure (or whatever its called) folder on the FAT32 partition.

I have done that, but it wont work, i've cleared cache too,
Btw how much time does it take on the first boot?

dont know, sorry, i've never used a sense rom, but i've seen posts referring to a good ten minutes or more, depending on the sd card and teh rom being installed, and how much stuff is moved to sd. Some roms just put just the app and dalvik folders there, some put much much more.
If it were me, i recon id be pulling teh battery at 10 mins.

do you have a 1gb partition on your sd card?
is the partition information for the rom correct?
are you using magldr or clk?

I have Tried wit a 2GB and a 1GB partition, I have Magldr 1.13, The Cwm size is also correct, 400mb for a 300mb rom.

You're absolutely sure the ROM you're trying to use is correct for the type of Android bootloader you have? (clk/magldr)
Did you check the MD5 sum of the rom.zip you downloaded? Maybe you got a bad download.
Did you wipe EVERYTHING? (full wipe, then in advanced, wipe dalvik and cache)
What method did you use to partition your sd card?

For now i Have followed the exact instructions from the DHD Desire rom, and it seems to work, I think the problem was wit the CWM recovery, I downloaded it from the Rom's page and it worked.

When I tried installing another Rom, I encountered the same prob, so I installed recovery again and it worked. Do I have to keep changing the recovery every time I put another Rom?

Yeah, some roms require different partition layouts, which are made when you flash CWM recovery.
If you are going from one rom to another and they both require the same partition layout, or if the new rom you're flashing requires a smaller system partition than your current rom, then you won't have to re-flash CWM. In that case, you'd just have to do a full wipe and then flash ur new rom.
The required/recommended CWM partition size is usually somewhere in the first few posts of the thread you download the rom from.

Cab't run NEXUS-HD2 rom

Hi there,
I wanna try the Tytung's rom NEXUS-HD2 ICS rom but It won't start. Install looks to be ok, nothing special happens, but when I reboot the phone, I only got "HTC" in green letters on my HD2 screen. Anyone got any idea about this problem?
Thank you for your help.

Hello
to get useful help, please explain what you exactly did.

I put the rom on my sd card, then I used HD2 Android Nand toolkit to repartition the phone : system 200MB, Cache size 45MB.
I reboot the phone, use the ad recovery to install zip from SD card. The install performs with no problem, with the "install complete" message at the end. I reboot the phone, it turns on, and then nothing happens, just the HTC logo on the screen. I can wait several minutes, nothing else happens.

45 MB cache size? Tytung recommends 2MB and I think is enough. Did you wipe everything (factory reset, cache, Dalvik cache) in recovery before install rom?

Hi
Most responses in the Main thread "stuck on HTC Logo" say that the system partition is too small. If there are any bad blocks in NAND can not reach 200MB.
I use ClockworkMod 5.0.2.7 with 250M system and 10M cach partition and have no problems except the known issues, that descriped in the first post.
Before i have installed the rom, i flashed HSPL2.08, Radio 2.15.50.40, Magldr 1.13.

Try wiping Nand and reflash

[SOLVED] Task29 or multiple formats?

I've been reading .. and in my readings I've read different people saying different things . I heard running task29 a lot can cause bad blocks .. and I flash a lot of ROMs . So I created a task29 zip flash from recovery which formats all nand partitions 3 times in a row to wipe out everything . Is that good for the memory and is that enough to wipe everything clean or should I use task29 every time and not worry about that being the cause of bad blocks ? In short , which is safer ?

Well do the math,, task 29 wipes every block once, your zip wipes some three times, which would you suspect as being there times more likely to end in bad blocks?
To be honest what's the point? In 999 out of 1000 flashes its enough to do a 'wipe data factory reset' and then flash.

Well , in every ROM thread ive read , it says to task29 before flashing . and i thought task29 was a more "harsh" way of wiping the nand . Like a format , does it not just clear the blocks without writing to them ? I personally think either way is still "not good" for the flash memory . But i could be wrong . And i always thought there were "leftovers" from just doing a factory reset ?

In my opinion, task29 is very unnecessary.
Only do it if your device is having issues, otherwise flash roms and bootloaders directly without task29'ing.
By the way, by "task29" they mean empty-rom.nbh .. not empty-rom.zip .
As for the .zip, a full wipe does the same.

A full wipe cleans all partitions of the nand ? i thought it just did /userdata . and thank you thats what i thought task29 was . but is flashing an empty .nbh worse then running the format command ?

Let me clarify a few things for you:
Task29: removes everything off your device's internal memory, when you boot your phone after a task29 you will get stuck at bootscreen (first splash), because there is nothing on your device (no bootloader).
Under CWM:
Wipe data/factory reset is different from format that can be found in (mount & storage):
Wipe data/factory reset: does not remove your OS, it will only delete your personal data retaining your ROM intact.
But a format will completely remove your ROM and you will be stuck at the bootscreen if you do so.
Every thing under CWM does not touch your device's bootloader (cLK or MAGLDR), and they only affect the Android ROM within CWM.
Hope this help you

Yes this i knew thanks though . My question is this , is it safer to wipe the bootloader off using task29 , then starting over , or is it safer to format all partitions of the NAND in CWM before changing to another ROM ?

I don't know which is safer. (or in other words, I don't know which is dangerous )
But if you must do a wipe, I'd recommend "Wipe data/factory reset" . That should do the job. (Most roms format partitions upon installation anyway so I coudn't care less )

it also wipes cache partition, the sd-ext partition on your sd card, and clears the .android folder on the fat32 part of the sd card. These last two are the reason many roms wont boot after flashing, even with a task29, since those two areas aren't touched by task29 (or your format zip presumably)
Im with Marvlesz, steer away from task29, , whats the use in removing magldr and cwm only to reflash it?
For me, a clean install would be ,,, cwm - wipe data factory reset - flash the new rom.
Only if the fresh rom doesn't boot after a few times rebooting (and performing a wipe data on the fresh rom, just like how in winmo it was recommended to do a hard reset straight after flashing) would i consider a task29.

Okay thanks ! I wasnt sure if the single format they do upon installation was enough . Ive been getting small app crashes in some ROM's ive tried , so i formated each partition at least once before flashing the ROM and it fixed it . I remember when flashing WinMo ROMs a task29 was a must on my Rhodium . But i was pretty sure wiping the partitions in CWM was indeed good enough . I just kept getting confused when each ROM's thread said YOU MUST TASK29 so i was like well now im just confused lol . I'll mark thread solved

Thanks again guys !

For me clean install means first do a factory/data reset. Will clean ext, and previous roms leftover folders. Then i will go to mounts in cwm. Do format every thing i got except sd.
On next boot, magldr, cwm is there. But no boot or rom. Then from magldr, i go to cwm and install the zip. I barely had done task 29 2 times in 3 mnths, just for repartition. ( though its not needed for repartition).

[Q] How to remove NAND Rom and keep SD rom

Hi all,
I previously had a NAND install of android working fine on my device, i did test a SD install in parallel for the few last weeks and i'd like to stay with it.
I setup MAGLDR to boot to my SD Android but i would like to clean the NAND install, do you know how i could do this?
The NAND Rom i'd like to remove: http://forum.xda-developers.com/showthread.php?t=1945425
The SD ROM i'd like to keep: http://nexushd2android.tytung.com/nexushd2-gingerbread/v3-3/download
thanks in advance for your answers,

Nuke everything with task29, install magldr, install the rom you want. You should get the same results using CWM and wiping everything from the menu.

Thank you for your answer.
I just have one last question about the impact of the wipes from CWM.
I don't understand which rom will be impacted my the "wipe data/factory reset" from CWM, the NAND rom? the SD? both?
Is there a solution only to wipe the NAND rom and not to touch my SD rom?
thank you again for your help,

I don't feel qualified to talk about this, but here's my understanding. CWM will only mess with your phone storage and remove everything there. The SD rom will stay on your SD card (unless you formated or partitioned that too), so as long as you have magldr set to boot from SD it'll boot the rom you want with nand being gone.
All I know is that if I were in your position, I'd wipe everything, both the card and phone, and just put the rom back again on SD. You can't miss with that. Make sure you backup the stuff you want from your card before you format it, should you decide to do so.

The wipe data/factory reset option will wipe the ROM on your NAND and your SD EXT partition but shouldn't affect your SD ROM. If you're worried then just backup your data.img from your SD ROM to your PC before wiping.
