Thanks for your help ripper1, I understand.

I just scanned all the topics I could find about FW2852 and U0 and bricking. There is exactly 1 user who claims he flashed u-boot-nand.bin to U0 and ended up with a brick. The few other reports (2 or 3) all flashed u-boot.bin (note the missing -nand in the filename) instead.

It appears that most people flashed 0.6.1.2_1.4.587_OV2655/u-boot-nand.bin to U0 using IUW. I flashed the one from 0.6.1.5_1.4.587_GT2005 at first, then found that my camera didn't work anymore so I reflashed U0 with OV2655/u-boot-nand.bin instead. Twice.

If anyone's adventurous enough to do this for their non-working froyo install let us know how this works out.

I'll be offline for the rest of today, but keep the answers to the questions I asked above rollin' in!

hello guys...

I ve been following this thread from the beginning and I tried some of your cool stuff. You guys are cool. In any event I would like to let you know that I have the same issue with the frozen Android logo BUT....accidentally I managed to get to the home screen. After it freezes I reset the unit using the reset button. I kept the sd in the lower port and powered up the tablet again. It shows the INFOTMIC logo and after a while the equalizer screen...Then it restarts..then the Android logo. Note that I have a usb mouse connected and at the moment its about to freeze I keep clicking the mouse buttons. It freezes for a second and then it keeps rolling the Android logo color forever. I restart the unit and it goes through the regular infotmic...equalizer...android screens and then to the homepage.

BUT it freezes ones it shows the homepage.

I hope this helps!

Hi All..... I have just done the 2.2 install and have suffered from the freeze screen with it just saying android! However.........

When I turn off the wireless switch the tablet boots!! Can someone else try this and see if this is a commen fix? Once mine has booted though the touch screen is not working so I cannot slide to unlock.

Please someone let me know if this works for them!!

Upgrading from 3245 with your new img file

@ Stragulus

Thanks for all your hard work I know the few people who have been able to upgrade are very happy and just for that you deserve praise! As to myself I still get stuck at the android screen freezed, I have posted the txt dumps from the SD Card in hopes to figure out what's wrong. I will wait until it is the last choice before doing the 2852, until I have better written instructions, but for now I am content going back to 3245 while you work. You are doing an amazing job, I will keep beta testing the files you upload and send logs. If you want me to try any particular steps, let me know. I'm from a windows envirement, I will try to redo the steps from a linux machine, to test it out.
[Android Software/Hacking General [Developers Only]] stragulus:
So..from the dmesg outputs I have at least been able to detect 1 difference between the working and stalling tablets:

The kernel command line:

For working tablets:

console=ttySAC3,115200 androidboot.mode=normal bmagic=0xdb6db610 hwver=0.6.1.5

For non-working tablets:

console=ttySAC3,115200 androidboot.mode=normal bmagic=0xdb6db610

See how the working tablets have the hwver parameter with..the u-boot version number in it? More support for the U0 theory!

Sadly I can't just add that parameter as that is determined by u-boot. But...the sd-card seems to boot with its own u-boot version. So I put on my forensics cap and went looking for it. And lo and behold, there's a hidden fat partition!

Linux buffs can see for themselves.Get the aben.start sector.001 file (just search for it, you'll find it), and mount it:

sudo mount -o loop,offset=$((0x10e00)) -t vfat sector.001 /mnt/tmp

Maybe I can use this to modify the u-boot on there to boot the v2852 kernel with the correct command line, and the ramdisk as used by the froyo firmware.

(EDIT) Too much dreaming, sadly..there's no u-boot on there at all, nor a kernel or ramdisk. It's just a filesystem cut short. Looks like someone just took a bootable card and grabbed the first 8MB off it. I think the u-boot already on the tablet just looks for the presence of some magic bytes and a folder named android in the root. Oh well.
[Android Software/Hacking General [Developers Only]] stragulus:
Ok, for those with stalling tablets, there's a totally harmless way to boot the tablet using burntool and custom boot parameters. You will need to have the tablet still installed with the froyo firmware.

Write the image in this zip file to an sd-card just like you did with the bootable one (winhex, imager, ..): http://www.mediafire.com/?tm561h5p3in7se7

Turn tablet off, and put the sd-card in the top slot of the tablet

Connect tablet with USB to PC and launch burntool. In burntool, click 'setting' and select the options as in the image:

Select the uImage from the bootable sd-card (or from the 2852 firmware, which is identical).

As command line, fil in:

androidboot.mode=normal bmagic=0xdb6db610 noinitrd init=/init root=/dev/mmcblk0p1 rootfstype=ext2 ro rootwait hwver=0.6.1.5

Click the bottom-left button to save the settings.

Turn on the tablet with menu+home pressed + power (you have used burntool before I assume), and when the square turns green, click 'start'.

You should see after a little while that the kernel boots on the tablet, and next it should show the equalizer and then the android image.

Maybe the added 'hwver' parameter will make a difference now, and it will fully boot. I do not have very high hopes on this, but you never know.
[Android Software/Hacking General [Developers Only]] ripper1:
Well so much for 2.2 on this pad ,me and burntool and winhex have never gotten along no biggy have a archos 101 that blows rings around the superpad that i use pretty much every day. thx stragulus for all your time and help
[Android Software/Hacking General [Developers Only]] Jiggity Janx:
...

EDIT: What I mean is, does the burn of the 2852 to sd to install on tablet carry the uboot.nand with it?

EDIT2: It appears you cannot update the uboot.nand without burning with burntool...

...

yet somehow I did it previously...

So I update U-Boot-Nand, and then i had got the versionsnumber in the right corner.

After this i flashed 2.2 and works fine.

[Android Software/Hacking General [Developers Only]] JD_1971:
Thanks Strugulus

@Stragulus,

Many many thanks for providing this NAND rom.

The update went perfect via the SD card method (after i Figured out that in WinHEx you need to select the SD card under the Physical media section instead of the Logical media section). Before this FroYo update I had the latest firmware (3245) installed and running.

The only think in my case which doesn't work is the default Youtube app. Aftre the app is launch, at the point were the video overview is shown, the app ends without any error or message. Even after cleaning the YouTube cache and other data, the problem stays.

Further i have no problems found and everything seems to work fine (Also my SD card in bottom slot!).

So many thanks and I hope your ROM will eventually run an all Superpad/Flytouch2 tablet without the Android logo hang problem.

So again many thanks for your work!!!

Best regards,

John

@bachhaupten did you update U-boot- Nand with a usb male to male or by another way?

cause this is the concept i don't understand very well yet...

Ap2SD doesnt seem to be working..

tried in the App info area and also installed ap2sd pro..

Giving me a failed to move message.. might be tied in to the sdcard problems..

as said.. I do have a sdcard slot working.. bottom one..

Gave the tab a good push along today.. no crash's and all still working fine..

I also updated "warm 2.2" to my htc evo.. so am playing with both at the moment..

You need a USB A-A Cabel.

Then i used the u-boot-nand from the 2852 in the folder 0.6.1.2_1.4.587_OV2655

Its very important to use the u-boot-nand, not the u-boot. The u-boot will damage our tablet, only the u-boot-nand works.

I flashed the u-boot-nand with iuw1.1 to U0.

After this short flash (the board make crazy thinks, but wait), I had got the versionsnumber in the rigt corner.

After this I flashed via SDcard the 2.2 like Stragulus in two steps.

It works.

Hi stragulus,

Nice job and thanks for sd froyo method. It works fine for the moment. I have not tested exhaustively the entire fonctionnality. But i'll let you know, il i found somthing wrong.

Would you mind explaining us how did you manage to create the system.tar.gz file under the stage2 directory of the image file. Because i would like to try other system.tar.gz.

I can replace the original system.tar.gz (extract the file and replace with another file) but when i flash the new one it hangs on the "equalizer" screen.

Any clues please.

Thanks in advance.
[Android Software/Hacking General [Developers Only]] ovisoftblue:
Uploaded the u-boot-nand from the 2655 directory, three times.

It still doesn't show any version number on the screen and still does the same android logo freezing trick.

What windows did you guys use? I tried on both win7 and xp, same result. My burntool is V0.75. Could that be the fault?
[Android Software/Hacking General [Developers Only]] F-P:
Updated from 3245 took a couple of goes, 90% of my problems have been the SD card so try more than one. I have the non working card slot slot same as everyone else. Also my market crashes on opening but that might be my previous fiddling to get paid apps working. Appplanet also will not let me install apps download fails.
[Android Software/Hacking General [Developers Only]] stragulus:
Thanks for trying this and confirming that it is indeed U-boot that needs to be updated!

I won't have much time the coming days/weekend but I'll try to squeeze in the sd-card fix. What I changed compared to the first release is /system/etc/vold.fstab, for those who want to experiment with it in the mean time. It's no rocket science, just google around for it and only look at other froyo examples, as the format changed after android-2.1. Also, look for errors using 'adb logcat' once connected using adb (see below).

Instructions to modify anything on your tablet:

make sure you have a wifi or ethernet connection

connect to tablet using adb: adb connect '192.168.3.10:5555' (replace 192.168.3.10 with IP of your tablet, which you can find if you install Android System Info app)

login on tablet: adb -s '192.168.3.10:5555' shell (again, ip)

become root: su

give yourself a slightly more useful shell with command history: exec busybox ash

remount /system read-write: busybox mount -n -o remount,rw /dev/block/mtdblock3 /system

modify whatever you want on /system (eg adb push/pull files)

remount system read-only: busybox mount -n -o remount,ro /dev/block/mtdblock3 /system

Also, you can modify system.tar.gz that is on the bootable sd-card. Important to know here is that you have to keep all permissions intact! Example on linux:

mkdir system
cd system
sudo tar -xzpf /path/to/system.tar.gz # do NOT omit the p!
# edit whatever you like, then recreate tarball:
cd system
sudo tar -cpzf /path/to/new/system.tar.gz .

The flash method requires an md5 checksum to be present if you want to flash it using the bootable sd-card, so you'll have to create one as well:

md5sum system.tar.gz | cut -d' ' -f1 > system.tar.gz.md5

Replace the system.tar.gz and system.tar.gz.md5 on the flash card, and reflash! Although it would be much better to create an update.zip for the recovery mode so that you don't reflash everything every time (including losing /data). I'm not sure how exactly that must be done yet.

What happens when you use the IUW tool to create an SD-card to update the tablet? Does it put the u-boot-nand.bin in the android/ folder perhaps? Maybe u-boot can be flashed using an sd-card as well. That would make the release a lot easier.

Information is free, but I'd rather not have it, the flash method does no error checking so it might just make things more confusing. Just be a little patient with the new releases, it's only out a very short time ;)
[Android Software/Hacking General [Developers Only]] Mr.Krulez:
sorry but fluidodinamics and aerodynamics are killing my brain so I don't really understand what u said to me. You were referring to the files or to the firmware of the ft3?
[Android Software/Hacking General [Developers Only]] stragulus:
The link to the sd-card. The new ft3 firmware is definitely worth investigating. Although from what I've read so far about the flash_player.apk is that it's dog-slow.
[Android Software/Hacking General [Developers Only]] Mr.Krulez:
Edited. XD

yeah you're right i read that is really slow, but i think it's better that don't have it at all especially if there is an easy way to cange the update.

But I'm not very pratical with modifics of a firmware so i don't know if it won't worth the time someone have to spent

If you don't see the version number on the infotmic bootscreen (see video) it will most likely freeze. I recommend holding off for now until we've figured out if the required u-boot flashing can be done through the sd-card as well.

[Android Software/Hacking General [Developers Only]] Jiggity Janx:
Start with firmware much earlier than 2852

I think of importance is post 82 HERE that shows that 6.1.5 started as early as having 1480. It shows 1561 update as having 6.1.5(585) which someone on this thread has already confirmed is working with the update.

I do recall that one person on another forum (androidtablets or slatedroid) converted one of the burntool only firmwares to sd install (update.zip or sd). Maybe it was the 1561? Trying to find the thread and version and the files now.

EDIT: Maybe an "ah ha!" moment. Could the difference people are experiencing have to do with whether or not they updated OTA from 1170 to1561?!?
[Android Software/Hacking General [Developers Only]] lambrosfl:
Guys check this out...

go to this page epad.hk (I can post the full link....the new user regulation thing:confused:) just put the Ws and the dot before the epad.hk

All the official FWs and manufacturer specs.

Flytouch is "IN" Series.

The ZT-181 under the ZT Series has 90% the same specs as the Flytouch....but there is a 2.2 official FW release.

Stragulus I hope this helps....maybe you can use the ZT-181 2.2 FW to develop an update.zip for flytouch....

Also if I am not mistaken APAD has an identical model as Flytouch (same CPU and memory) running Android 2.2. I will try to et some more info for you.
[Android Software/Hacking General [Developers Only]] Jiggity Janx:
That is what I had asked at first in my post as well. :D But digging into other forums some appeared to show that the files burned to sd using burntool still requires the uboot to be burned prior using usb. So I edited the post and took that part out.

If someone wants to try it out, by all means do so and let us know the results.

Sd Fix

Hi Stragulus. I downloaded the first version you posted some posts ago, as with the last version I had none of the two sd slots working.

Then I solved in this way:

#1 Step: Modifying /system/etc/vold.fstab in:

(...)
# dev_mount right_sdcard /sdcard2 auto /devices/platform/goldfish_mmc.1 /devices/platform/msm_sdcc.3/mmc_host/mmc1
dev_mount sdcard1 /mnt/udisk1 auto /devices/platform/imapx200_sdi0.0/mmc_host/mmc0
dev_mount sdcard2 /mnt/sdcard auto /devices/platform/imapx200_sdi1.1/mmc_host/mmc1

(...)

I mounted sdcard1 to udisk1 just for testing. It should be rewritten as:

dev_mount sdcard1 /mnt/sdcard1 auto /devices/platform/imapx200_sdi0.0/mmc_host/mmc0
dev_mount sdcard2 /mnt/sdcard2 auto /devices/platform/imapx200_sdi1.1/mmc_host/mmc1

But those mountpoints must be created before, as you surely know. See #2 below.

#2 step: modified /init.rc in:

(...)
# create mountpoints
mkdir /mnt 0775 root system
mkdir /mnt/sdcard1 0000 system system
# by rex
mkdir /mnt/sdcard2 0000 system system
mkdir /mnt/udisk1 0000 system system
mkdir /mnt/udisk2 0000 system system
(...)

I modified this, but, on restart, the modified file was overwritten with the previous. I immagine it has to be flashed to stay in the modified version.

#3 step: I think that also /system/etc/mountd.conf should be modified but I couldn't try, as I couldn't have sdcard1 and sdcard2 directories created.

Hope these things help! :)

Well, finally i did it!! somefearsabout burning u-boot-nand, but was very easy...

step by step:

Get a a USB A-A Cable (5 € on Barcelona, spain)

-Then i used the u-boot-nand from the 2852 in the folder 0.6.1.2_1.4.587_OV2655 (first, need to charge drivers in iuw1.1. I can only did it on XP, no vista no W7 wors...) on XP, as usual very easy...

- CAUTION!! use the u-boot-nand, NOT the u-boot. The u-boot will damage your tablet, only the u-boot-nand works. So better get it (u-boot-nand) and put in desktop or other place, far away than the damned twin (u-boot hahaha)

- flashed it (the u-boot-nand with iuw1.1 to U0) stragulus download a pic very clearly feww posts before)

-After this short flash (the board goes crazy...colors and srtange messages, but wait for a normal activity and rebbot), finaly got the versionsnumber in the rigt corner.

-After this I flashed via SDcard the 2.2 like Stragulus in two steps.

Now, works... and now wants to check every app...

thanks stragulus and company!! next step....gingerbread!!

[Android Software/Hacking General [Developers Only]] finitol:
Which one did you download??
[Android Software/Hacking General [Developers Only]] Jiggity Janx:
If people updated from 1170 to 1561 they most likely skipped the 1480 update (that I know I installed) which is where the 6.1.5 was noted to have appeared! Some people got their tablet with 1480 on it so no matter what update they did from there would have the newer ubootnand.

If you (or anyone) is willing, install the 1480 update from post 8 HERE and let us know if you get the 6.1.5 on the Infotmic screen. From there you should easily install froyo.

*Of note is that the recovery file in the 1480 update is named recovery_rd.img where the rest of updates have just recovery.img. This possibly differentiates between a full and update version.
