Update:

Been playing with msm_nand.c but it is slowly adding bad blocks to my nand :( Not sure if my nand is starting to fail or playing with msm_nand driver is causing it to fail. I have a total of 6 bad sectors now and if I get to 8, I will have to stop and explore yaffs instead of pursuing the driver.

Update:

END OF THE ROAD for me....now I get multiple bad blocks and I am unable to install Android. I think my NAND is actually failing. Any ideas on how to fix the bad blocks? LMK.
[Tilt, TyTN II, MDA Vario III Android Development] scooter1556:
Do you still get the bad blocks with clean build of the kernel from git? What exactly did you modify in the nand driver? it's strange how the two things have coincided.
[Tilt, TyTN II, MDA Vario III Android Development] n2rjt:
When I tried one of your kernels last month, I had four bad blocks instead of my normal two. When I went back to the standard kernel, the bad blocks went back to two. Grasping at a different straw, maybe try WM65 rom, then flash back to a standard Android kernel?

If the experimental kernel is better at detecting badness, we are all in trouble and really can't use that approach. If, on the other hand, the bad blocks are false positives, there is still hope if someone can take up the cause.

Installed Windows 6 OK but it is stuck on the initial screen with R 1.64.06.04 G 25.70.40.02H D 3.03.00.00, doesn't boot any further, I can get to bootloader mode though and that's about it, thinking about task 2a but I'm pretty sure that could brick this further, have they solved the issues with task 2a?

Update:

I have like 612 bad sectors as per MTTY (Now I have like 800 bad sectors)

I can't even do a task2a because I have 3.56Hard-SPL installed

Any ideas?
[Tilt, TyTN II, MDA Vario III Android Development] n2rjt:
Wow.. at least we know the damage is real.

Sounds like either this experiment is at an end or you need a new kaiser. I have a second kaiser, but is sd reader is broken, and I think that is the same board as the nand.
[Tilt, TyTN II, MDA Vario III Android Development] clemsyn:
I agree that my kaiser is dying :( but that doesn't stop me from releasing the last nbh I have before tuning msm_nand.c :) Will release it soon with an androidupdate.tar. BTW, I can still get it to work, I just have to give the system the whole Nand partition and give data to SD to get it running :) Any donations will be appreciated.
[Tilt, TyTN II, MDA Vario III Android Development] clemsyn:
I have enabled support for EXT4 in the kernel and was able to install data to this via SD partition install. I will post instructions in the second post.

How I can update yaffs2?
[Tilt, TyTN II, MDA Vario III Android Development] l1q1d:
@clemsyn: did you change the initrd and install scripts? These changes block the backwards compatibility...
[Tilt, TyTN II, MDA Vario III Android Development] albe695:
no 3g

The kernel with ext4 support works fine for me. The only problem is that 3g connetion doesn't work. Am I the only one?
[Tilt, TyTN II, MDA Vario III Android Development] clemsyn:
On the kernel with ext4, I did. I also disable ext2/ext3 kernel support coz it won't fit with ext4 support added.
[Tilt, TyTN II, MDA Vario III Android Development] acompres:
Everytime i try to install to SD Partition it says "Umount: Can't umount /Data : Invalid Argument." I did all the steps according to the mini guide, and nothing.

you can't install it using atools, i will update it soon
[Tilt, TyTN II, MDA Vario III Android Development] acompres:
I'm not using atools, just good ol' HTC Flasher on ubuntu, and that's pretty much it.
[Tilt, TyTN II, MDA Vario III Android Development] clemsyn:
Check your SD card and make sure the third partition is still ext4. If it is, try try to reinstall again and don't clear the data. Also make sure you use the kaisimg kernel on the second post.
[Tilt, TyTN II, MDA Vario III Android Development] vArrow:
I have this problem too, no 3G connection.

Hoping to have a solution for this.
[Tilt, TyTN II, MDA Vario III Android Development] clemsyn:
I currently have no 3g data here in US but my Edge connection is working OK (via web2go).
[Tilt, TyTN II, MDA Vario III Android Development] scooter1556:
Clemsyn, is there any reason you wanted ext4 in the kernel for data on sd? Have you read about any advantages? I've always been under the impression that ext2 is the best filesystem to use on flash memory because it doesn't employ journaling which takes up more space and causes more write cycles to the card. Ext2 is a much simpler filesystem and uses less RAM to run so in theory the phone will run faster using it. Has anyone noticed any speed improvement using an ext4 partition? I know journaling offers security on hard disks with operating systems and important data and makes searching faster but none of this really comes into play here.
[Tilt, TyTN II, MDA Vario III Android Development] clemsyn:
Journaling is currently disabled on this kernel with ext4 and IMO ext4 is faster than ext2 with a few bells and whistles :)
[Tilt, TyTN II, MDA Vario III Android Development] tiagoclc:
Is data on ext4 fast as data on nand?

Clemsyn, do you have some benchmark results?
[Tilt, TyTN II, MDA Vario III Android Development] scooter1556:
Thanks for the reply Clemsyn, it's an interesting one, I thought that you would probably have disabled journaling. Still not sure the extra overhead in terms of RAM for running the ext4 driver is worthit on our device even though there have been other improvements between ext2 and ext4. Be good to get some benchmarks, I wouldn't have thought there would be a great deal in it. Not that I'm worried, I'm running on NAND, just interested to know if it is a big enough improvement to warrant the amount of kernel space it takes up.
[Tilt, TyTN II, MDA Vario III Android Development] tiagoclc:
Converting ext2 to ext4 using adb

Didnt work...

Please, delete this post.
[Tilt, TyTN II, MDA Vario III Android Development] l1q1d:
with the mke2fs inside initrd you can only generate ext2 fs, but you can mount it as ext4.
[Tilt, TyTN II, MDA Vario III Android Development] tiagoclc:
...and using tune2fs i can convert ext2 to ext4.

You can clearly see when you mount the partition using "mount /dev/block/mmcblk0p3 /somedirectory"

when you type mount, after mounting the partition, you verify that it was mounted as ext4.

But the phone is very slow when using ext4 on sdcard.
[Tilt, TyTN II, MDA Vario III Android Development] Krazy-Killa:
No data connection at all with this kernel, and also because of no data connection, I cannot use Google Sync to bring over contacts.

clem, is there anything changed with this kernel than with all the others, cause data worked flawlessly on all of l1q1ds' and even some of yours, but the ext4 kernel, 3G, and E does not work.

WiFi is flawless though, but useless to me without Google Sync.

Anyone have a clue as how to update your Prl? Not PRI.... I've read a couple threads and no solid leads that work...
[Droid Incredible Q&A, Help & Troubleshooting] kaslasma:
Dial *228 and select option #2. Alternatively you can dial *22899 and it bypasses the automated menu and updates the PRL list.

Remember, there are different PRL lists, a list for Verizon and a hybrid Verizon-Alltel list. There may be others but those are the two for sure.

[Galaxy Tab General] w4rmk:
I have a brand new AT&T Tab and need assistance. I am able to install non-marketplace apps using Sideload Wonder Machine however I have an interesting problem. I have an app (Lotus Notes Installer) that itself downloads another app and tries to install it but I get the dreaded "For security, your phone is set to block installation of applications not obtained from Android Market" message.

I have installed and run z4root and did a temporary root and also installed Superuser and Busybox and I still get the block message.

I am an Android newbie and don't know exactly how to proceed.

Thanks,

Richard
[Galaxy Tab General] GiggleGut:
Hey Richard,

I had the same type of problem you did with my AT&T SGT. I also used the Sideload Wonder Machine. Here is link for my situation. http://xdaforums.com/showthread.php?t=914697

Lotus Note Installer app downloading and installing another app? I have not hit that kind of hurdle. Can you get your hands on the apk that Lotus Note Installer is trying to download and install? Maybe you can istall that through sideload wonder machine?
[Galaxy Tab General] bdl1969:
This may be a stupid question, but have you set your Tab to allow installing of non-market apps? It's in Settings - Applications - check 'Unknown sources'
[Galaxy Tab General] w4rmk:
I do not see an option in my settings for "allow unknown sources", here's what I have:

Settings>Application

Manage Applications

- this doesn't appear to have any options for unknown sources settings

Running Services

- this is only for stopping running services

Development

- only options here are USB debugging, stay awake, allow mock locations

Am I missing something? or did AT&T remove the option from recently shipping tabs? (got mine yesterday)
[Galaxy Tab General] w4rmk:
I was able to sideload the Notes Installer, but once on the Tab, that application connects to the corporate server and attemtps to install another application on the Tab and that is where I get stuck.
[Galaxy Tab General] cbb77:
Use SuperOneClick. This tool not only allow rooting but has option for allowing install of non-market apps. Simply select that option and it will update your systems settings to allow installs from other than market - sd card, web, etc. I am also using AT&T tab and this worked for me. Note it does not add the menu option of "allow apps from unknown sources" but trust me it works.
[Galaxy Tab General] w4rmk:
I installed the new firmware that allows me to make phone calls using the great instructions provided in theis forum and that resolved my issue and now i can install the Lotus Notes app with no problem. I am really liking the new O/S, it seems a little snappier than the the AT&T one.
[Galaxy Tab General] foxmeister:
You missed nothing - this is just another retarded AT&T carrier customization that they do on all their Android phones (AFAIK!).

Regards,

[Galaxy Tab General] w4rmk:
Yup, AT&T has removed the "install non-market apps" menu option from their retail Tabs. Very sad that they do that to their customers. I will say the I like their approach to selling the Tab, you pay the retail price and their is no contract to worry about and if you want data you pay on a month-to-month basis, exactly like they do with the Apple iPad. I cannot image getting a subsidized Tab from T-Mobile and getting stuck with a 2 year contract. In this market nobody keeps a phone or tablet for 2 years, it would be a dinosaur by then.
[Captivate Q&A, Help & Troubleshooting] doctahjeph:
I guy I know wants to trade me his unlocked HD2 for my Captivate. Now I am on AT&T so I will only get Edge speeds if I trade for the HD2. I think I might be okay with this as I use WiFi more than 3G anyways. HD2 has the bigger screen, and is very very versatile when it comes to loading different OSes on them. With the HD2 I could have WP7 and Android at the same time. Captivate has the smaller, but better screen, has 3G, but pretty locked down when it comes to the OS. What do you guys think?

how do i take doubletwist off and format it?
[HD2 General] saurabh88:
try panasonic sd formater with full erasr on
[HD2 General] babours:
Hi,

You can try this:

Hold "-" volume button, then push power button, install a "MAGLDR" then boot on it and use the "usb mass storage", then use the SDformatter file to format your SD, all this informations are "sticked" on XDA forum in section "nand development", easy to find it, if it don't works, then try to use an external adapter to put your SD card on card reader...

Hope will work, cya !

[Nook Color General] Guy_Fawx:
Last week, the power button on my Nook Color broke, so I've been trying to get it returned to B&N for a replacement. However, having rooted and changed the device, I'd like to restore it to factory settings, but I have no way to power off the device or boot it into recovery to reflash the stock firmware/recovery. I've tried the ADB command "reboot recovery", but it only reboots the device.

Any help would be greatly appreciated, because I'm not too confident in opening the device myself and trying to fix it.

Edit: I've tried DDing the original files also, but have way too much trouble formatting my SD card properly. I'm going to continue trying to do that, but in the meantime, help getting into recovery would make the process much easier on me.

Thanks again.

[Galaxy Tab General] onemoredeal:
I successfully flash from Roto pre-rooted JME v4 rom back to stock ATT rom ( also provided by Roto ), and to JME v4 again.

What I did in last couple of days:

I got the ATT tab and didn't activate the SIM card. I rooted the tab and flashed the tab with Roto pre-rooted JME v4 rom ( as mentioned in many posts, root is not a pre-requisite of flashing Roto's rom ).

I used an iPhone SIM card in the Tab. Both the voice and data worked. I even got 'H" ( HSUPA) on the signal bar while the iPhone with the same SIM card only shows '3G', probably because I flashed the Tab with Bell modem.

However, I found it is not very convenient for me to use the Tab as the main phone. So, I want to activate the original SIM card that comes with the Tab and only use data on Tab, which I thought I could only do that by using the stock ATT rom ( if anyone knows a different way, you can share it ).

So, I used odin and flashed the ATT stock rom posted by Roto. The flash process is very easy. NO re-partion, no PIT, no modem. I just put the ATT stock rom into 'PDA' part in the odin and click 'START'.

After I flashed Tab back to the stock rom, I even got back the Samsung logo. No more black screen with bright line. Everything seems to be back to original state except that the tab still shows it is rooted when I check the firmware version ( I used super 1 click to root the Tab. Tried different ways to un-root. But the kernel still shows 'root'. If anyone knows how to completely unroot, please let me know. Thanks).

Since the original SIM card has been activated, I thought it might be better to flash the Tab again to JME and Bell modem. So, if I really want to use a SIM with voice plan, I can.

Flashing to Roto's JME v4 for the 2nd time was very easy again. I just followed the quick tutorial in this forum ( I did the re-partition. maybe it is not needed). Everything went smoothly. The only caveat is that I got the single bright line with black screen during booting for a couple of seconds.

Now, I am back on JME with Bell modem and original data-only SIM card. I set the APN to the settings for data-only SIM. The original SIM card just works.

I found a lot of ppl asking about flashing back to stock rom. I feel it may be useful to share my experience. Sorry for I didn't put the references to the posts regarding flashing and rooting.

Big thanks to Roto.

I do have a few questions for this whole process:

1. How to un-root?

2. I am now using the JME rom. I saw 2 APNs in the mobile network settings. 1 for AT&T activation used to activate the SIM with voice plan, another for ATT Broadband used by data-only SIM. The activation APN for SIM with voice keep coming back even after I deleted it. And it also seems it takes a lit too long in 'checking SIM' during booting. Does anyone know how to remove the activation APN?
[Galaxy Tab General] cbb77:
I am afraid I can not answer your question however I do have a question for you. I am still running stock firmware and plan to upgrade soon. However would like to be able to get to same stock version I have now if possible. Can you list the baseband/firmware of the stock AT&T you obtained and rolled back to?
[Galaxy Tab General] onemoredeal:
I used the Roto's stock ATT rom. The firmware version is xxxxUCJK1. I believe that is the right stock firmware version as I have also seem it been mentioned in various other websites.

Since you are still using the stock rom, it is good opportunity for you to back up everything:

Roto Backup - http://xdaforums.com/showthread.php?t=850359
[Galaxy Tab General] cbb77:
Thanks. That is the current version I am running. I will probably upgrade this week. I have already taken a Roto backup as well as used Titanium Backup. I also have screen shots of every screen I could bring up. I think I am all set; just need to pull the trigger and do it.
[Galaxy Tab General] webvan:
I was able to unroot with SuperOneClick, will now be flashing back to AT&T stock!

UPDATE 1 - Oops...Odin stays stuck at "SetupConnection", any tips on circumventing that? A search didn't find any fix for now :-(

UPDATE 2 - ok, started with ON+Volume down and Odin worked...BUT I get the AT&T splash screen and then it goes to the "recovery menu" (the one you get with ON+Volume Up")

The yellow lines read :

Any way to get out of this mess ? Thanks !

UPDATE 3 - taking the SIM card out solved that, phew !
[Nook Color General] Sheen160:
Hey guys, so I'll cut right to the chase. I'm debating on getting the Nook Color or the Notion Ink Adam. I know it's hard to compare the two because of the specs but hear me out. All I really want it for is web browsing, occasional gaming, and flash videos. My laptop of 5 years is crapping out on me. Every now and then it'll overheat and crash right when Im reading some xda or phandroid. :p But anyways, the nook color IS cheaper and can be overclocked to 1ghz but it's smaller, doesn't have as much RAM and not dual core. But as I said I only really want it for browsing. So would it be good for that? And can it handle flash videos well? Thanks for the help.

inb4 replies bashing the Adam :rolleyes:
[Nook Color General] ph00ny:
notion ink
[Nook Color General] Sheen160:
Care to explain why?
[Nook Color General] spikey911:
Not sure about the specs on the Ink, but right now there really isn't any flash on the Nook.. There is some progress on it, but it requires Froyo of course and that is not ready for prime time yet.

There is much talk about other roms, but doesn't look like that will happen anytime soon.

If the Ink has flash and if that's what you need then your probably better off with something certain.

I bought the Nook with the assumption we would eventually get flash, but I am starting to question if I made the right choice myself. Its an excellent piece of hardware and worth the price, but my fear is it could get abandoned with all the new tablets out...
[Nook Color General] Sheen160:
No flash isn't really a deal breaker for me. If I really needed it I could just use it on my X. I think it will eventually be on the Adam. But the money thing is what's holding me back. 120 bucks is a lot of a difference. I'm just considering trying the nook and if I dont like it ill return it.
[Nook Color General] Kohr-Ah:
Think of it as do you want an ereader that has been hacked to be a tablet or do you want it more of just a tablet (which you can add reader apps to). If you want more of a tablet function go notion ink. If you want more use as just an ereader than a tablet go nook
[Nook Color General] john10101:
i bought the nc because i did not want to wait for the Adam. I am very happy with the Nook. It suits my needs for now. one thing i really like about the nook, is the hacking. From what i see the Adam is going to have a pretty well baked interface when you get it. its faster, and offers the pixel qi screen which interests me a lot. the total cost of the device with shipping is a bit of a turn off, but it will have more manufacture development then the nook ever will.

For the 250$ price point the nook is a superior product in every way. but there's still a bit of things that are lacking on the nook. but every day someone posts something in the dev form that gets me more and more interested.

i suggest you go to bestbuy, buy a nook, and play with it for a few weeks, see if you like what it has. if you want more return it. no harm. its very easy to reset back to stock for a return.
[Nook Color General] fixitsteve:
Cost. The main issue is cost. For 250, I think there is no beating the NC. The GTab lasted 1 day at home. For the cost, it wasn't worth it...

NF will soon be very stable and capable. It gets better every day. The screen is great, form factor is great, community is great, and you never lose the fact that it can be returned to stock to be a great e-reader when something new comes out. It will always be a very capable little tablet even after you have transitioned to a new device.
[Nook Color General] fixitsteve:
Oh, and good luck getting your hands on a Notion. Initial quality problems and backorders will keep it out of most people's hands for a while...
[Nook Color General] naplesbill:
I was a little torn between the NC and Notion Ink myself. The bottom line, for me anyway, is the form factor. I personally think the Nook is the perfect size.
[Nook Color General] kynibe:
I was on the same boat as you but I saw my friend Nook rooted and that seal the deal for me. I have no regret and this have become the go to gadget at home between me and my wife.
