[Q] Flashing another ROM over an existing ROM? - HD2 Android Q&A, Help & Troubleshooting and Genera

Apologies if I am at all asking a question that has been answered before (forum search did not help much), but I am trying to find out how to safely flash a different ROM onto my device.
I have installed HSPL3, Radio 2.15, MAGLDR 1.13, ClockworkMod Recovery and NexusHD2-Gingerbread V2.7 using the NAND method.
I want to shop around and check a few different ROM's before donating to the one that suits my needs, but I need to know if it is simply a case of flashing a new ROM over the existing one using the same methods or is it slightly more complicated than that?
Thanks.

Ugh no need to flash over hspl, magldr, or radio. Just use cwm to flash it. However depending on the rom, you may need to flash a different cwm. Eg. Cyano is the 150mb partition, sense is the biggest partition.

Hi,
If I were you ,I would backup your existing ROM in CWM(go to backup and restore).
That way if your next ROM is no good or if there is any problem,you can easily restore the original.
Before you install a new ROM,READ the [OP] carefully ,paying special attention to the size of the new recovery partition.
Then you can flash the new recovery partition,wipe data,cache partition and dalvik(in advanced),
then install zip from sd card.

Do I need to clear anything for smaller ROMS/MODS?
I currently am running the latest GingerTh3ory Rom with its respective radio. Then in it's candystor3 app I downloaded the 'honeycomb battery' full mod pack so that it uses a honeycomb UI with the battery and small things like that.
When I change the battery and do system and individual MODS should I clear anything? I don't want to slow my phone down by keep flashing MODS over top of one another? My friend convinced me to root and so now I'm getting used to this.
Any help is much appreciated!
Thanks

I have come to find that most new Rom's usually will format everything needed when you are flashing over another Rom. Just to be cautious go into CWM and maually fomat Boot, system, cache, sd-ext(if applies) data, and then go to advanced and wipe Dalvik cache...

Realy, what is the benefict of the Recovery ?

The idea is very well, but every build has its own recovery (or flash.cfg) so instead of using only the sdacrd for flashing (the original idea) now we must use the 2 things : the usb flasher with DAF and the update.zip in the sdacrd
Really did you have to post this question here?
This is an important question. I don't quite understand the idea as well. I don't think anyone has explained anything here like that, especially taking in consideration that we've never used android before except just recently.
really intereseted in that answer to!
but for me another question is: what is the special thing about a2sd+ ?
I did not use recovery yet but isn't it that you flash the recovery 1 time and than you can download the .zip and flash roms via the recovery.
OR
You don't flash it via recovery but just via DAF.exe like I do at this moment.
The a2sd+ makes a part of your SD card act like it's internal storage so you can install more apps than on 280mb that is left when you don't have the 1024leo phone (usa = leo1024 , eur = leo512).
1. You can make a full backup of your system so if you hose your data you can wipe and restore back to the last backup.
2. You can install new roms from the microsd card as long as the system partition fits what you have set. Some people prefer it that way, and some people have bad usb ports and need it that way.

it must be like that, but in the real world, every rom builder, uses differents MTD partitions sizes, so we have to reflash its recovery again, even if we have already flashed it before with the defaults sizes (150, 250 or 400 MB)
Why every build do not uses a standard sizes, fixed by the Recovery builder, RaiderX303 ?
RaiderX303, you have make a very interesting work, thank you very match for that, but can you please continue you works and resolve this ?
Recovery allows people to download and flash roms from the SD card, no need for a pc except for the first time install using DAF to flash the partition layout, it allows people to switch easily between roms, some people like myself have a Rom they prefer to use, when a new Rom comes out that looks good I can backup the Rom I'm using and flash the new Rom, if I don't like the new Rom I can flash back to my old Rom and not lose any data

Hey guys, i'm using MJD's 2.1. I thought the benefit of ClockworkMod was to enable me to go into recovery from the reboot menu. Also, it was supposed to allow me to reset to factory settings. It seems that none of that is working.
If I reboot into bootloader or recovery it just reboots into Android again. Resetting to factory settings does absolutely nothing apart from rebooting.
What am I doing wrong?

[Q] Flashing Clockworkmod on MAGLDR 1.13

Hi All,
I've been looking for an answer and have not found one yet.
I have an existing NAND build (MDJ cyanogen 7) of android that I flashed via magldr 1.11. I know I can update magldr to 1.13 safely without messing deleting the the nand rom i have already. But if I want to install Clockworkmod 1.3 onto the nand will I lose my existing rom need to reflash my rom again or does magldr know to flash clockworkmod onto another area of nand that wont overwrite my existing rom?
also with clockworkmod it says:
Download recovery with partition size for the type of rom you plan on using, see guide below if unsure.
it says to use the 150MB partition just wanted to see if anyone else using mdj's cyanogen 7 is using the same thing?
Your help is greatly appreciated

Yes you will lose your current rom, so do a cwm backup first. After flashing the partition for cwm, you will get a kernel error on first boot, so boot into AD Recovery and restore the boot, system and data backups and all is back to normal. As for the partition size, use the same size as you did for the sd version. The guide suggests a 400mb partition for an unsquashed desire hd build, but I used the 250mb partition on my current rom and all is perfect.
PS! Please don't post questions in the ROM Dev section, there's a reason why there is a Q&A section.

Its so frustrating, why on earth would anybody post a question topic in here when we have dedicated Q&A forum??
It should be obvious to anybody that this is a "dev" forum for posting developments not for asking questions.
Since the rom was originally flashed via DAF, will CWM still allow me to do a backup?
Was hoping for a guide, it's so confusing.
No, from what I understand you don't have CWM installed yet, so you can't use it now. Use titanium backup (market), and then flash cwm so you can use it in the future.

It seems confusing at first but it is not really that difficult.

Correct, on first flash of cwm it will erase all data/roms etc on NAND. You will not be able to backup the rom if it was initially flashed via daf. As StephanV says, use Titanium Backup or MyBackup Root to back up your data/apps etc and you can restore them after.
Once you have cwm installed and have flashed a new rom and set it all up, then you can do a cwm backup.
So if i use cwm then I can only flash zip based roms from that point on? I cant use the daf ones anymore then.
You can still use daf, but each time you run a daf file it will remove the cwm recovery partition and you will need to reflash it to use cwm again.
I'm finding that if i flash cwm ontop of a daf rom the rom becomes unbootable. and the only way to get it to work again is use a cwm version of the rom.

i'm not sure about the rom you are using but i was able to back up a few different roms with cwm which i installed using daf. this is what i did:
1. create a folder on sdcard name "cwm" (you can name it whatever you want). i actually have a folder for each clockwork recovery version.
2. put the zImage and initrd.gz for cwm (version 1.0,1.1,or 1.2) in the folder you just created. (do not flash anything at this point)
3. boot into magldr and go to services, boot settings, ad sd dir and select the directory you just created
4. now in magldr menu boot ad sd, and you should hopefully boot into clockwork
5. go to backup and restore and backup your rom. if you try cwm 1.2 and it doesn't work try 1.0 to back it up, you can then update to 1.2 again and it will still restore just fine.
6. before restoring your rom, install cwm1.3 and choose a partition size bigger than the size of the system.img of the rom that you backed up. clockwork backs up your rom in your sdcard->clockworkmod->backup. it creates a folder with the timestamp.
7. now you can follow the steps from the clockworkmod thread to load cwm1.3 and restore from there.

dont bother 'installing' clockwork, just put the two files on your sd card, then go into your MDJcyanogen rom folder on the PC, open (in notepad) flash.cfg and it will look something like
boot ya|boot|ro filesize+1M boot.img
misc ya 1M
recovery ya|ro 3M
cache ya 3M
system ya filesize system.img
userdata ya|asize|hr allsize
the partitions 'recovery' and 'misc' will allow cwm to work, they arent needed for this rom, they are only there for compatibility however if you plan on flashing to a different rom using sd card/cwm, (rather than simply using cwm to do backups of MDJcyanogen) you will want to edit the
system ya filesize system.img
and maybe set it to one of teh recommended cwm sizes, example
system ya 150M
this is because the original line
system ya filesize system.img
will set a system partition of the same size as the MDJcyanogen system.img, (about 130meg) but if your next rom has a bigger system.img, when you try load it from cwm it wont fit, so wont work. by setting it to 150 (or whatever you want) you are allowing for different size system.img in various roms.
Whenever you flash a nand rom, so long as you edit the flash.cfg and make sure those two partitions, misc and recovery (and maybe cache too, i do) are there, then cwm will work.

[Q] Quick Question: full backup?

Hi, a quick question.. If I am using a desire based rom (NAND) and I want to back up as much as I can (apps, configs, contacts, everything?) to test another nand rom without having to install and set up everything, what is the best way to do this? I am new on this. Thanks! I appreciate it.
Use CWM to backup and restore everything (apps, settings, messages... everything)
Select AD SD in MAGLDR (or AD Recovery) and follow the logical prompts.
To restore, follow the same steps but choose 'restore' rather than 'backup'.

Agreed, but if you have NAND rom installed without CWR, then you can use Titanium Backup program from market. Do not install CWR if you do not have it currently. As it will wipe everything from your phone.
On other note if you are not using CWR then start using it. It is the best thing you can have.
But, can I use CWR with every rom out there? or the rom has to be installed via CWR to be able to recovery?

You won't be able to use every rom out there on CWR. But there are only couple of ROMs like that. Mostly all the devs are moving towards CWR. If you have TMOUS HD2 then i would recommend 400MB partition CWR, so you will not have to edit those partitions for different ROMs.
And just in case you want to try new NAND build which does not have CWR version, you can definitely do that. Later you can install CWR again and get your old ROM back after you try new one.

Ok, thing is right now I am on a build installed via DAF, and I want to try another one, I will search more about CWR and make a full backup with Titanium pro.. thanks for the advice!

How can I wipe my android rom from my hd2 and start fresh?

What I'm trying to say is, when I got my hd2 It already had magldr 1.13 and a nice gingerbread rom installed. What I want to know is how can I go back to a clean Leo and start fresh so that I can learn how to install android myself. I could use some help with the i android install afterward as well. thanks in advance.

You could use the hd2 toolkit from this post. It will wipe your rom (task29 option), install mgldr, then you would be good to go to install recovery and another rom.
I have just been using it, its a great tool. I think this would only apply to nand roms, sd roms maybe do it differently?
Peace
Edit: also, I found post #4 from this thread invaluable help for flashing my first leo android rom.
If you truly want to go to a "Fresh LEO" download a stock leo winmo rom, change the .exe to .zip find the RUU or something like RUU_signed.nbh ( should be like 270MB in size) and change the name to LEOIMG.NBH and transfer it a 4GB or less microSD card and insert into phone. Start the phone holding the red power button and the volume down button. it should go into the bootloader and flash stock radio/spl/rom and you can start from scratch. CM7 was the best thing to happen to the HD2. CAN'T WAIT FOR CM9!!!!
Okay people now I REALLY need your help, okay so I flashed clockwork mod recovery through magldr, and thats working fine, but after doing so, when it tries to boot it says something like failed to load kernel, so I figured that roms toast so I used the option in magldr to "Ad hard reset" because the hd2 toolkits task 29 wipe kept failing as well. So I need help finding a rom that will install from clockwork mod recovery. Im hoping it will take care if my kernel problem. Any links to Cwm roms would be great and thanks in advance.

Pretty much any newer ROM will be flashed through CWM. Just look at the OP and flash the correct partition size, then place the 'MAGLDR' version of the ROM (zipped folder) on your SD card and flash
Wait lemme see if I have this correct. When I see roms that say magldr version, I can flash THOSE through CWM recovery? If u could help me find cm7 that I can flash through cwm I'd be most appreciative. Thanks again.

Any CM7 ROM in the NAND Development section really. Typhoon, Hyperdroid, Dorimanx etc.
first check the CWM recovery requirements of the ROM(it will say something like CWM 5/120/5) then check your current recovery if its the same. If not you need to download the zip file for the CWM recovery required by the ROM. unzip the file on a computer and run the .exe and follow prompts on the screen(doing this will completely delete the current ROM install on your phones internal memory). Once the correct recovery is flash on your phone, you can flash the ROM itself

Absolute clean setup of a new rom?

I want to change my present ROM. The best and correct way of doing this is:
Flashing stock WinMo - flashing radio - flashing magldr - flashing recovery - flashing New Rom
Did I miss something? Flashing again HSPL is necessary?
why go thru all that bother? i just factory wipe from cwm and then repartition if necessary and isntall the rom
never had a single issue

Definitely do not recommend doing that. Read about 'bad blocks' (search on XDA) for some more information about this sort of stuff, but if I were you, I would just do a data wipe in CWM, flash a new partition layout if needed then install the zip from SD card. This way you don't end up flashing a billion different things again and again every time you consider changing ROMs (which is quite likely now with the release of ICS and stuff)
If the install as I suggested fails I still wouldn't recommend going back to WinMo. A simple Task29 should suffice.
task 29. thats it. lol
Task 29, I read a lot of contoversial statements about this tool. Ok so wiping data and cache will be just enough as I understood.

There is nothing wrong with running a t29 for a clean install
How I do a clean install:
1. T29
2. Flash radio 2.15
3. Flash MAGLDR
4. Boot into MAGLDR, then Android Recovery
5. Partition/format SDCard
6. Mount USB, transfer .zip to root of SD
7. Wipe data
8. Flash .zip
9. Boot
