[Q] Android wont boot on SDHC card?

Hello all, first post here.
I just bought an HD2 from eBay and it's in immaculate condition. I checked the HSPL and it was 1.66 Cotulla. Along with the phone came a 2GB SD card, to which I put darkstones FroyoStone 2.2 with Sense; and it has been working perfectly with no issues (except battery lasts about 12 hours with average usage).
However I want to install and test other builds on my 8GB SDHC which I have lying around. I have formatted this many times to GUID/MacFS, ext3 and FAT32 over it's lifespan.
When I tried to boot Android on my Omnia i900, I had an error with the SD Card and it never loaded; now when I boot the same or different Android ROMs on the HD2, they never boot. Even the exact ROM I have working on a 2GB SD card that I am using as a daily is not working on this card.
Could anybody help me with this issue?

sounds like the sdcard may have died from all the formats/flash's...
do you have a partition manager program etc that can check the card its self? most linex based partition programs will tell you if you have dead blocks.
personaly if im takeing a card thats had all sorts of partitions thrown at it, i format it, wipe it, then do a 0 wipe, this usualy fix's it.

Can I do this using the OSX Disk Utility to 'Zero Out' all the data or should I boot into Ubuntu and somehow get gParted working?
Thanks

i have no experiance with osx, but yes, gparted will usualy do the trick.

disk utility worked, thanks for the help. saves me buying a new card

good to hear! its amazing how much faster things run on a clean card...
format people!

I have question that goes with this one....I am running core series V4.1 it has the andriod boot on the windows side and I used one andriod build in this mode , but when I try others it seems it does want to go? What could be the issue?

Seems I just booted up Evo Core series on my phone, WOW i may never back to windows

tried your idea now ,, didnt work.

I've had the same problem with the latest roms released this week, so I'm assuming it MIGHT have to do with th kernel that they have in common). When it gets stuck on 2nd boot, I simply pull out battery and try again. From then on I don't have this problem anymore each time I boot using clrcad and haret. I'm not bothered to change kernel and the latest seems to be best, thanks to the dev's hard work.

Have you tried another build? I am on revolution 1.7 with s7.1 kernel, I have the second boot issue, I just pull battery out, reboot and there I am, no more issues.
You can't boot HD so try revolution.
I also use exceller to autoboot under 3 seconds.

thank you , i shall try that again,, do you have a link to 1.7 revolution ?

Are you using one of those Class 6 or Class 4 MicroSDHC cards?
If so, replace it with a Class 2 Sandisk or a Class 2 Kingston MicroSDHC card.
In order to achieve Class 6 or higher standards for MicroSDHC cards, some manufacturers uses tweaking, which saves cost in making a "real" class 6 media card. These tweaks causes different problems in different devices. Tweaks may include increasing sequential read speed, but will cause random reads/writes to not be stable.
Which is probably a reason why Microsoft Phone 7 won't allow you to use your own MicroSDHC except the one they approve, and they are still working on the list.

do you mean the Temp android folder created after the booting ?

so far i tried the 1.7 revolution and i tried to reboot it once , and it worked gonna give it a go for a couple of days and feed you back
many thanks all for your help

You can also try the following:
1. Download the Android build once again
2. Backup your SD card to your desktop PC
3. Delete the Android folder from the backup just made
4. Reformat your SD card
5. Restore your backup to the SD card
6. Extract your Android build to the SD card
7. Boot Android

had the same Problems with the older kernel and the newest radio..using mdeejay, too.
I changed the radio to 2.12.50.02_2 and set up the newest hastarin kernel together with the titanium Energy Rom and now it works out perfektly

@ OP, this should be in the general section.

I had same problem before. Try to run a check disk thru windows under the removable drive tools. Also have it check for bad sectors.

[RESOLVED] [Q] Any1 successed with 16GB Kingston -NAND ROM (ext4onSD)

EDIT: It does seem (beyond reasonable doubt) that the Kingston 16GB is at fault here. It has been reported by other users too. I've tried about 3 different NAND (data2sd) roms on the Kingston and they all took very,very long on first boot (minimum 30 mins). There was also an awful lag on all three ROMS.
Tried the the same ROMs with my standard SanDisk 2GB that came with the HD2 (anyone know what class it is? 2?) Anyway, with this card, all ROMS took about 5 mins on first boot and no lag whatsoever.
Currently looking for another card; Kingston is going straight back! Any suggestions, an Sandisk 8GB @ class4/6 perhaps?
I have two HD2s. One I used to test a NAND install with san disk 2gb sd and that works fine.
So I thought I'd buy a Kingston 16GB class 4 for my main HD2- performed exactly the same procedure as the first (everything but the card is the same) but the phone keeps getting stuck at the green HTC logo.
A non-ext4onSD/data2sd ROM seems to run fine though.
I have partitioned the card with standard sizes, 1024 ext (tried 3 and 4). Used Clockwork and Gparted but both result in the same thing.
Is it a case that this card simply doesn't work. How can I 'clean' the NAND memory and start over (if that would even help)?
Thanks.

How long did you wait?

The longest time was 40 minutes.
It was relatively quick on my first HD2 and that is still working fine.
I think I need to 'wipe' the NAND somehow as when trying a 2gb san disk it still hangs at the HTC logo.

16g card

Is a 16g card to big for the nook? On most dl's I see 2g, 4g, 8g, etc but no 16g.

No. 16GB is not too big.
The NC maxxes out at 32GB.

Is our CM7 also running off the card? (noobie question). I recently placed the CM7 on a Sandisk card, 16m, Class2 and all my MP4 videos are choppy or out of sync. I've tried several video players.
A related question: Is the SD image of CM7 the same as the stable version of the EMMC version since the video is reported to be working great in that version.

I' only loading movie files from the 32G uSD. Running CM7 from eMMC. I did run CM7 from a uSD a while ago on a Transend 8G Class 6 which the consensus seems to be the card to use. Class 6 seems to be the "sweet spot". Others have run Class 10s with very mixed results. Lower class ditto.
As far as the version of CM....I don't believe so. The stable signed is 7.0 (7.02) and have not personally seen a uSD version but I could be wrong.
(Edit): Try using VitalPlayer. My sotware of choice.

The "class" of an sdcard measures the sequential read/write speed. The deciding factor for how well an sdcard would run a rom seems to be something else: the small block random read/write speed (which does not seem to be listed on the package); see
http://forum.xda-developers.com/showthread.php?t=1005633&page=2
for an interesting discussion & data (esp OP and post #19). Speaking for myself, I had a great deal of troubles running nookie froyo on two class 6 cards, but I had no problem using a cheap class 2 sandisk. You guess it: the sandisk's small block r/w speeds is almost 10 ten that of the two class 6. Right now I'm running CM7.02 on a class 4 sandisk and it's running great.
YMMV.

Updating the SD Card
I had used the image from Verygreen's link which is 7.0.0-RC2 but re-reading his original post it appears I can just copy the latest build from
"mirror.teamdouche.net/?device=encore"
and copy into the first partition then reboot in recovery.
Can someone comfirm this will still work? I'm having issues with choppy video and terrible battery life - though I realize the battery life is much less than stock. The stable version, 7.0.2 was suppose to address many issues and from reports is running great.
Thanks!

I have a 16 GB card and I'm glad to hear it will work. However, which image should I use? Why isn't there a dedicated image for the 16 GB size? Will I only be able to use half my card?

Sounds great - Thanks. I realized that I could just make my own image using Winimage of my current working CM7 SD install and use it to re-flash if things messup. ( slaps head, duh). I am confused about this from Verygreen's post:
OC Kernel installation instructions:
After you have a running CM7 by doing the steps above.
Get CM7 OC kernel from Dalingrin's thread. Unpack the zip file, the result should be a file with the name "kernel" and some other stuff. Rename the kernel file to uImage.
Shutdown your nook and take the uSD card out (make sure the nook is not plugged into USB bus or it'll boot into eMMC then).
Plug the SD Card into the computer, copy uImage file you just created to the first partition (the partition name would be "boot") instead of the existing file with this name (might want to save the original file just in case).
Now you are ready to go again.
You'll need to repeat these steps every time you upgrade to a new nightly build, because they carry their own kernels with them.
Is this still necesssary? The first section instructs to place the newest build .zip image on the 1st partition and recovery boot - the install works like the original install. Also do I need to also re-install Gaaps?
Thanks - I searched Verygreen's long thread but could not find the answer or a link to Dalingrin's thread.
EDIT: Nevermind - I'm learning... so the Kernel is the basic element that is found in the image file. Different beast than placing the .zip image on the sdcard.

10 char doublepost

I am not sure about the size of the card, but what matters more IMHO are the real-world sequential read and write speeds. I purchased a 4GB Class 10 Patriot uSD card and loaded CM7 per Evergreen's instructions. The performance is TERRIBLE, slow and market d/l is extremely slow as well. I attribute this to Patriot misrepresenting the sequential write speeds of the card. I would go with Sandisk Class 4 uSD or Transcend Class 6 uSD (on order) as well as other Brand uSD cards reported by XDA users to run CM7 well on NC.

It works great
Flashed the latest CM7 7.0.2 to my Sandisk 16g, Class 2. Movies play great with several different players. Still want a better class sd card and will use suggestions found in this forum. I swear, is it more fun to see movies play great on my nook or just trying different "hacks". Love this forum.
Thanks to all those who help us newbies.

I bought a 16GB Sandisk (class 4) card today to replace a Transcend 8GB class 6 -- unlike the Transcend, which I had *maybe* 1-2 Fcs total in the 3 days I've had it running, I've been getting errors and FCs not infrequently with the new card
I even tried wiping it and installing fresh downloads of CM7 and gapps to see if that was the problem.
Could it be I just had the bad luck to get a not-so-good Sandisk card?
I'm running the CM7 (stable) install w/ multi-boot menu, only OC'ing to 925mhz via Cyanogenmod settings for both cards. No launcher mod, just a bunch of game apps, moboplayer, quickpic (same set of apps on both cards). Can't figure out why I'm getting random FCs otherwise in the Sandisk card...any ideas?
------ updated : -------
Ran diagnostics on card, everything (including physical surface check) came back clear. r/w scores were OK (a bit low on the r/w 4ks) but nothing terrible.
When I used a different installer all my FC issues dissapeared. The one I had been using (and still have on my Transcend 8GB card) is the 2GB (extendable 4th partition) + multiboot install. It runs flawlessly on the 8GB card but for some reason caused my 16GB install to crash a lot (FCs and error messages).
When I installed verygreen's agnostic SD card version, the issues I was having on 16GB disappeared. Running very smoothly @ 925Mhz CM7 OC. I've thrown a bunch of movies at it and it looks great, no chop. So YMMV.

Get 16 GB VeryGreen's generic card (preformatted) here

Isn't the point of verygreen's size-agnostic image that you can install it on any size card? I used it on a Sandisk unclassed (so, 2) 16GB from Radioshack, and CM7.0.2 is running great--much smoother than stock 1.2 on the eMMC.

As others have said, it's not the sequential r/w but the small-block, random r/w that counts for running an OS, and class ignores this benchmark entirely. Your Patriot was very likely performing exactly as advertised, but what it's advertising is how well it will perform in a 10+megapixel DSLR camera taking rapid-fire photos or a half-hour video. It gains that performance at the expense of small-block r/w, sometimes gaining 5-10x the sequential r/w by sacrificing 100x or greater the small-block speed.

Yes, but there are several posts regarding issues with the mke2fs failing on 16GB cards.... that is why I made the 16 GB version available....
I tried with 3 different 16 GB cards that would fail... so I presented my solution for 16 GB cards.

I was having problems with the 2GB expandable install on my 16GB card (ok on my 8GB). Just wiped and installed verygreen's agnostic and so far no FCs or oddities that I've noticed; if I start having issues I'll try yours thanks for posting it!

CM7 on 16 GB Kingston...slow as molasses!
I finally got everything copied, imaged, written, etc. It's working...except being able to access the SD card to move all my stuff onto it...but SLOW!
Should I just chalk it up to the card or are there other settings or things to check? I was a bit overwhelmed by the CM7 settings/options...lot of things there...
Thanks
