Ummmm...

Hi all,

Just had this tablet delivered today - first Android device I've used, so I'm a complete n00b on this. HAving a massive problem with the battery so tried rooting the tablet using zroot and gingerbreak to no avail. I can't get my head round the chinese website with the updates - does anyone have a link, or advice/instructions on how to root this tablet? I am aware I've got to rename/disable the telephony files as that's what's sucking the life out of the battery... pulling my hair out...

Thanks in advance

Oh and it's running 2.3.1, kernel version 2.6.35.7-tcc

Thanks Fun_, much appreciated. Other thing - does anyone have any installation files for windows? I tried to root it using superoneclick, but when I connected the tablet to my PC it keeps coming up with the Found New Hardware wizard and prompts me (as usual) to install the software for the 'M801_88'. But I haven't got it.:mad:

I bought this tablet from ebay being sold as a 'Kulpad' - google it if you need to.

Bargain for the price, but I REALLY want to sort out the battery issue on this as it's all getting sucked up by the phone function.

Actually Tinybeetle I didn't *facepalms* - I've just powered the tablet back up and power's still getting sucked up by the aerial. Turns out I have Super User access (have the Super User icon in apps plus checked by DLing Terminal Emulator and typing 'su' - displayed a '#', so all good. HOWEVER, I've just tried renaming the Phone.apk MMS.apk and Telephonyprovider.apk on my tablet using ES File Explorer and it says 'sorry, operation failed!' Bah. Any advice guys?
[Android Q&A, Help & Troubleshooting] SergPro:
ES File Explorer doesn't suit for such job, you need a file manager app that can utilize root rights. For example - Root explorer, some other also exist.

WBR, Serg.

Make sure BusyBox is installed and updated.
[Android Q&A, Help & Troubleshooting] Jasio_m:
You can enable the root options in the menus of ES File Explorer and re-mount the filesystem read-write. You should then be able to rename the files. I used the terminal emulator to do it.

The battery life seems a bit better since (that's on fun_'s CM7).
[Android Q&A, Help & Troubleshooting] Parastie:
Sadly, no it doesn't. Emdoor (the company that makes the EM73 which these devices are very similar to) said it is looking into adding support in an email to me, but that it takes time. I guess we'll have to wait and see.

OK - sorted. Didn't see that there was a little button at the top of the screen on Root Explorer with 'R/W' on it - clicked it and boom. Sorted. No more battery drain!

Display sleep problem

Hi,

i have a Ly-F521 tablet since last friday.

I'm completely new to android tablets, maybe i'm doing something wrong...

Display timeout is set to 1min. After this the display is in sleep mode.

Unfortunately, I cannot return from the sleep mode . I tried all kinds of buttons to return from standby, but the display stays black.

If i long push the return button a couple of seconds after the display goes to sleep, sometimes it works.. but if I wait 30sec. + ... no chance..

The only way to return to a running state is to switch off the tablet and reboot.

I installed the newest firmware (page 14) but same result.

What can I do? Am I doing something wrong? Hardware issue?

Many thanks for your help

Wifi also causes radiation, but hopefully not as much as 3G.

As far as i can see WIFI on average is allot less than 3g.

My 2 cents

Installed this FW (both files), on my SenseV7 - it still works :)

The good:

- touch screen seems to be more accurate (before I rarely could touch "back" button in the corner of screen)

- not shure, maybe it became more fast and responsible

- I've got a cool dark logo "Z slate" on boot :)

The bad:

- I've lost my nice boot picture with yellow fish :(

- sometimes I can't get apps on market (app not found), especially when installing from AppBrains. But if I search directly in market by app name - it mostly finds them.. But I couldnt find Google Sky at all

- when in sleep - it suddenly wakes up, waits a little and goes to sleep again. Maybe that's "push mail" working?

- battery meter still works weird - it comes to red zone (10% remaining) very quickly, and after that continues to work a couple of hours till shutdown

Not good nor bad - everything became very small on screen. I think its because of different screen density/DPI...

Hope this helps. If you have ideas how to solve "the bad" - would glad to hear them..

WBR, Serg
[Android Q&A, Help & Troubleshooting] tinybeetle:

I have a few questions if you don't mind.

Which FW version did you replace?

Was your screen set to 800x480, what do you mean by "very small on screen"?

Skype

I just wanted to report that yesterday I installed "Skype_2_0_0_47-signed.apk" from villianrom. Everything works except for video out on my LY-F521. Prior to this release I couldn't even get Skype to sign in.
[Android Q&A, Help & Troubleshooting] SergPro:
I'm sorry, but it seems that I've lost all backed-up files prior to upgrade :(

I only can remember, that it was Version 2.3.1.

May be - before the size of everything was like on other tablets with 800x480 resolution, but the image was more smooth.. But now everything on the screen looks very compact. See attached pictures.

So, not to say that this disturbs me much, but now the "quality" of letters is a little worse..

WBR, Serg
[Android Q&A, Help & Troubleshooting] tinybeetle:
Serg,

From your screen-shot it appears that you are indeed at 1024x600. My LY-F521 came with the 0517 fw and 2.3.3 pre-installed. So that is the resolution that I've always had. Even with the small text it is a phenomenal screen.

Tinybeetle
[Android Q&A, Help & Troubleshooting] SergPro:
I think I've found the reason - in the 0616 FW there is a parameter in system.prop file

ro.sf.lcd_density = 160

but in the 0427 FW from Merimobiles and 0517 from 99pad.com it is set to

ro.sf.lcd_density = 240

So, I'm going to try this out (after I get root :cool: ).

Updating the stock firmware without FWDN

I've only seen instructions to install the stock ROM update with FWDN. However, I don't have a Windows installation at hand, so no FWDN for me.

I've gathered that the fun_'s CM7 can be installed using ClockworkMod, but can also the stock firmware be updated using it? Installing the bootloader update seems especially worrisome.
[Android Q&A, Help & Troubleshooting] jampekka:
I decided to take a chance and start doing this on my own. I understood that the bootloader is same across 2.3.*-versions, so I decided not to update it at all.

The first thing was to install clockworkmod to make backups. Unfortunatedly there doesn't seem to be a way to navigate the stock recovery screen, so I took a chance and flashed the recovery.img from the LY-F521-8K-recovery-signed.zip using fastboot and it seems to work fine. The commands for this are (you may need to sudo the adb and fastboot commands on unix systems if you haven't configured the permissions):

1. adb reboot bootloader

2. Wait for the device to boot with a blank screen

3. fastboot flash recovery recovery.img

4. fastboot reboot

5. Wait for the device to boot

6. adb reboot recovery

7. Do your thing in ClockworkMod recovery. Home-button selects, menu-button navigates down and back goes back. There doesn't seem to be a way to go up, but it doesn't really matter. Didn't try the power-button though

If you're going to flash a new ROM, I suggest taking backups now in ClockworkMod recovery.

NOTE: THE UPDATE MAY NOT WORK FROM PRE 2.3-VERSIONS AS THIS PROCESS DOESN'T UPDATE THE BOOTLOADER!

Could somebody verify this?

To start flashing the stock ROM, it has to be unpacked first, with tools provided here: androtab.info/telechips/howtos/customize-firmware

To flash it, I used the following steps

1. adb reboot bootloader

2. fastboot flash boot boot.img

3. fastboot flash system system.img

4. fastboot reboot

The installation went without problems and the updated ROM seems to work fine.

There was some conflicting reports on how well the 2.3.3 (0517) works. For me it at least fixed the browser's google-crash, it recovers from sleep a lot faster, and may have fixed WLAN performance problems I had with 2.3.1.
[Android Q&A, Help & Troubleshooting] jampekka:
Did you manage to change this (and I assume you mean /system/build.prop)

I'm not able to root the device (at least after the update to 2.3.3). The problem seems to be that even with adb remount the /system isn't really writable. df claims that it has 0K used, although the directory only has some 130MB of 150MB actually used. And trying to add files causes out of memory -errors (I think the memory refers to the mtdblock in this case).
[Android Q&A, Help & Troubleshooting] SergPro:
Hi!

Just reflashed it with 0616 FW. There is really no place left to root it.

So, a little trick helps - just delete some "text to speech" files

adb root
adb remount
adb shell rm /system/tts/lang_pico/*

now df shows that I have 2M free on /system

And after that it is possible to root..

WBR, Serg
[Android Q&A, Help & Troubleshooting] fun_:
if you want, I can offer modified lk.rom to get +10MB /system. use lk_androtab.rom in FWDN.zip for LY-F521 on my site. (reflash mtd.img is also needed after lk.rom flashed & rebooted)
[Android Q&A, Help & Troubleshooting] jampekka:
I tried this (but with /system/app/Gmail.apk instead), but df still says 0K free. I also tried adb erase system before reflashing, but that didn't do anything either.

I think I'll try again with 0616. The problem may also be because of my fastboot-flashing.

Edit: This was my bad. Deleting the picotts stuff actually did work. For some reason it wasn't enough to delete the 1.5MB Gmail.apk

Do you know if there's any way to do flash these without FWDN?

I don't think you need to install any exploits, as the adb seems to run as root by default. So do the steps as described here: http://xdaforums.com/showthread.php?t=966624 but skip the ones with psneuter (or busybox, there is one already) The name of the adb-binary depends on your OS, but it is included in the SuperOneClick package.

Thanks Jampekka -

in fact my pad was not recognized by windows. I thought installing the vtc driver during firmware upgrading is sufficient, but I had to edit an android_winusb.inf with the hardware info I found at device manager as decribed at lunasalt.com/?p=1691 (japanese page but gooogle translated it quite well).

What´s the purpose of the VTC driver package anyway?

Now as the device is rooted I tried to install clockworkmod the usual way.

I did download LY-F521-8K-recovery-signed.zip, than renamed it to update.zip

and copied the file to ./mnt/sdcard and did a reboot holding menu+power also tried back+power

but no luck.....

I als tried to unzip the img file to the sdcard but again no luck....

do I miss anything??
[Android Q&A, Help & Troubleshooting] jampekka:
I don't think there's a way to boot in to recovery without adb, and even then the stock recovery is unusable. The standard way to install clockworkmod seems to be FWDN. Also using fastboot works fine.
