Hi,
I have an HD2 with MAGLDR and CWM. Now i want to update my Hyperdroid ROM because of some issues. The Last Time i did this, all my previous installed apps, sms and contacts are still there.
How can i make a complete clean installation of all this?
Thank you,

Enter cwm
Choose wipe data/ factory reset
Flash new rom.

I sugest to flash "daf.exe" application to recreate boot. And OFC from cwm partition/format SD if you want clean installation.
If you have problem with some roms, put task29 and fix permition
GL
flashing from zip overwrites the boot and system partition, and 'wipe data/factory reset' wipes sd-ext, cache, data and clears the .android folders on the fat32 partition, so unless you want to change the partition size, there is no extra benefit in reflashing cwm (which is what "flash daf.exe" means, for anyone that has only used the flashing tool) and as for task29,,, well i've always considered that to be superfluous except in times where things are genuinely wrong, and indeed doing a full "task29, cwm, rom flash" every time (some people even consider re-flashing hspl, the radio and magldr a 'clean' install ) hugely increase the load on the nand blocks, and considering the number of 'bad block' threads that have been coming up the last 6 months, keeping the number of writes,wipes and rewrites low has got to be top priority.
(course, just my thoughts, I'm no electronics engineer or dev )

Hello, I have recently been unable to flash ROM's succesfully.
I have Clockwork MOD 4.0.0.2 installed as it came with CF-Root, and I am on stock 2.3.5 KI3.
I have tried flashing several roms, and while it says install complete, whenever it restarts, it is on a boot loop, where it won't go past the Galaxy S II bit with the yellow triangle, I have to flash the stock rom again using odin to even use the phone, I have tried to flash other recovery versions, like 4.0.0.14 and 5.1.2.6 (I think it is) but they all come up with errors mounting or getting recovery.log or something, could you please help?
Did you try to do a full wipe?
Most issues can be resolved by this.
In the CWM menu chose the factory reset/full wipe. (Don't worry it won't touch your files on the internal SD card)
Do a cache wipe and in the advanced menu do a dalvik cache wipe.
Some recommend to do this procedure twice, but you should be settled with doing it once
Let me know if it helped?

Yeah I did all that, didn't help, the progress bar gets half way and says complete :S I have downloaded the ROMs several times aswell incase they were corrupt, still didn't help.
Take out the battery, wait a bit, put it back in. Do all the wipe and formatting procedures (perhaps twice) and format the internal sd card as well and wipe the battery stats (just to be sure)

Hi. Despite much searching I have been unable to locate exact information pertaining to my query. I purchased an HTC HD2 from ebay primarily because it is operating Android (Cyanogen Mod7) instead of Windows. The phone would appear not to have been factory reset and as a result I am unable to set up a Google account, etc. My knowledge is very limited but I want to do a factory reset but not delete the Android OS...how do I do this? MAGLDR V1.12 is installed and there is an option to hard reset but I do not want to end up with an empty device with no operating system. I do not have a memory card installed. Help would be appreciated. Thanks, Scott
1. turn phone on amd hold power button all the wayy through go go go as magLDR loads
2. choose AD Recovery ( option 5 i think?) in magLDR menu
3. once recovery boots up ... find the option to wipe user data ( sorry its been to long since ive had to wipe data from an old rom ;-)
^ the above (wipe data) is clearly marked as such!
this will reset to newly flashed shiny new fresh android rom
@rubledub - Is there an "ad recovery " option in magldr 1.12?
I started answering just as you have a few hours ago, but stopped when I realised magldr isn't 1.13.
also, be advised that some builds span the system as well as the sd-ext partition. the "factory reset" option in clockworkmod (CWM) wipes the sd-ext in addition to the data and few other partitions.
therefore, if you are using such a build that relies on the sd-ext, then format the relevant partitions manually. alternately, take a CWM backup, then use the "factory reset" option, and then do an "advanced restore" to restore the sd-ext portion (because it will have been wiped during the "factory reset").
you mentioned that it is a cyanogenmod build, which means it is VERY VERY LIKELY NOT relying on the sd-ext to store the build's system files, so "factory reset" inside CWM is the recommended option for you.
the above posts may be correct, i.e. magldr 1.12 might not have support for CWM...even if it does, the build installed might not be a CWM build (there are two types: CWM zip or magldr image).
just a few things to consider.
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).

I task29 everytime when i flash new rom. But i heard somewhere task29 make HD2 has bad blocks. Is that right?
I think when task29 it format NAND so i don't need to "wipe data, wipe cache, wipe dalvik-cache" because there are nothing on NAND. Right?
IMO (i did before & until now) the way to flash new rom:
Format SDCard.
Copy rom into SDCard in root folder.
Task29.
Install MAGLDR.
Partition.
Install rom from zip file.
Install addons (if any).
Reboot
Wait at least 10 minutes.
Config initial setup.
Wait at least 5 minutes after screen off.
Reboot.
Wait at least 5 minutes.
Use normally.
If don't use task29 when flash a new rom:
Format SDCard.
Copy rom into SDCard in root folder.
Partition.
Wipe data.
Wipe cache.
Wipe dalvik-cache.
Fix permission.
Install rom from zip file.
Install addons (if any)

Reboot.

If update new version of current rom:
Copy new version rom into SDCard in root folder.
Wipe dalvik-cache.
Install rom from zip file.
Install addons (if any).

Wait at least 10 minutes after reboot.

Please correct me if i'm wrong. Thanks.
I searched in forum & found many guides to flash rom but they are little different. English is not my native language. Sorry for my bad English.
Which is the right way to flash?
Thank you very much. Appreciate every replies.
i guess when you do a full wipe, ther is no need to do any other cleanig..
i always perform a full wipe, when flashing NAND roms and never had bad blocks, except very few times,where i think it's ROM's fault..
i hope i helped a little..

I have been using Task29 on every rom install I do, it has not failed me yet. Everyone needs to use this install guide, works perfect, READ and do not miss 1 step, and it will be perfect. best thing to come out for the HD2 trust me.

I very strongly disagree with the above post and the guide you posted. You're unnecessarily wasting time and effort and indeed repeated writing to the NAND can eventually lead to bad blocks, and the amount of times this is done is doubled if you do a full cycle with Task29. IMO, this is what should really be done when flashing a new ROM:
1. Copy ROM to SD
2. Repartition CWM
3. Flash ROM
Repartitioning CWM wipes everything anyway, so there's no point in wiping again. Really this is all that is needed, and I don't see why people do any more. I realise now that this may come across as insulting but I really don't mean it that way, I just find it a little annoying when someone posts 'do a Task29' as the first step in a guide, when it really is pointless
This is my way:
- Coppy ROM to sd card
- wip data cacth
- wip partition
- wip davich cacth
- install zip (ROM file) from sd card
- reboot
No need to format sd card

That is not a guide. Just only my way when i install new rom. In every guide of rom i see little different and i wonder is it right or wrong so i post here to get your opion.
Are there clearly documents about:
Wipe data.
Wipe cache partition.
Wipe dalvik-cache.
Fix permission.
I think when we know exactly what is wipe data, wipe cache, wipe dalvik-cache, fix permision, we can install rom in the right way.

You don't need to do a fix permissions. When you install a rom, the basic permissions are set through updater-script, and when you boot a rom, it is supposed to set all the permissions correctly through init.rc.
When you are coming from another rom, all you *need* to do is "wipe data/factory reset" (that option in CWM) and you are good to go.. Dalvik-cache resides in /data also (in most roms I have seen) so it is unecessary to wipe dalvik-cache again.

Exactly. The only other thing you might need to do would be to repartition CWM which should wipe the data anyway.
Hello people. Just wanted to ask how is the right way to wipe when flashing a rom WITHOUT losing the rom (wiping internal)? In CWM i just factory / reset data then thats it then clear cache and dalvik cache. In TWRP do i just need to swipe when the screen says "Most of the time this is the time that you need" when i will flash rom? Thanks for guiding!
anyone?
1. factory reset
2. advance, wipe system
thats all for me, works everytime... just make sure to wipe cache/dalvik after flashing zip files be it roms or gapps or whatever :good:
The default "most of the time" option is a fresh reset of the phone. it wont wipe the ROM itself, but all the data will be lost and you start over. Wiping system will remove everything, a ROM must be flashed after wiping system.
So before i flash a rom i wipe the "most of the time" then advanced format system? right?

No need to use format system unless you are installing a fresh ROM. Format system will remove everything from your device (other than sdcard info and all that). So you get a clean slate.
If you just want to flash an update to the same ROM you can either 'dirty flash', which I usually just wipe cahce/dalvik then flash the ROM and reboot, and you save all your user modified things, or you can wipe system and install the ROM. You lose everything that way so make backups.
Usually there isnt much need to factory reset unless you're having an issue with something. What is it you're trying to do?
I wanted to flash a stock based rom. Thank you.
