feel easy, almost of all chinese cheap pad is really cheap. many people get semi or fully broken tabet ;)

if hardware is fine, then you'll notice software has many bugs :)

disassemble/reassemble is one of pleasure for chipad. you can enjoy bug hunting too. (actually, just finding, no way to fix in many case)

Thanks for your reply, I'll keep playing with it and see if I can get it back alive. I did notice inside that 1 chip is actually on the ribbon to the screen. I'll post some strip down pictures of the device here once I've looked at it.

Maybe I'll order another one next month or wait and get one I can rely on.

that's something i believe i found on my own yesterday. W/o wi-fi turned on i've got my tablet on at 8 am, now its 12 pm - 4 hours, with some music listening and some usage, it got dropped 20%, which is possible, because i believe my battery is somehow broken and 1 second after removing the charger from 100% i've got 90%. So if i loose only 10% for 4 hours it's way better. Anyway the indicator sux, it shows difference of levels only with 10%, meaning 90-80-70, not 90.89.88 and so

Mine tablet was also 0613 originally. HDMI was not working (freeze) and it has that screen wakeup also. I upgaded to 0616 and HDMI works somehow, but device was very hot when plugged on HDMI cable. Logcat show's also a lot of gps related lines?

Today I downgraded to 0517 and HDMI works now okay. Logcat is now 'normal' and no screen wakeups's.

Some newest tablet's from e-ville has 0702 firmware inside!
[Android Q&A, Help & Troubleshooting] Bronic:
no wakeups at all?

how is battery in standby?

0616 has wakeups but quite less often than 0613
[Android Q&A, Help & Troubleshooting] Bronic:
uf, the wakeups started again, w/o installing new apps. wakelocks doesn't show anything special.

anyway - i can't find good gamed to test its performance. For now from the 3d stuff only speed forge is running - 22-30 fps for 3d game, it seems almost nice.

still, 2d games can't run, they are lagging as hell, i can't get it why - for example ragdoll cannon, which is way simplier graphics.
[Android Q&A, Help & Troubleshooting] tinybeetle:
I noticed the logcat GPS errors also. Is there a way to shut down the GPS service?

Are you sure the e-ville is really a 0702 fw? I've seen the 0616 labeled 0702, but it is really 0616. Someone else posted earlier that the 0702 release is 100% identical to the 0616.

Update: Hmm, according to this site (translated from Japanese) the 0702 fw that he installed is a 0622 version internally.

As it looks like my touchscreen is dead, does anyone have one from a tablet some some other issue that they can sell me (I'm in the UK)? I have contacted the supplier and they will no doubt get back to me eventually.

Or if for some reason one of the tweaks apps I installed (can't access the tablet to see what I was messing with at the time) managed to reset the TS firware did anyone find a fix for the badly flashed TS? I guess a reflash of the correct firmware would be good maybe via some adb shell commands.

hey guys,

just went back to orig. fw. (lyf521).

now i mentioned the x and y axis of the g-sensor are reversed.

where can i change these settings?

in the system/build.prop?

i tried in system/build.prop:

sensor.accelerometer.invert_y=1

sensor.accelerometer.invert_x=0

sensor.accelerometer.flip_xy=1

nothings changing...

and - what was the app i can change the rotating-parameters? (blame on me - i forgotten ;) - mean 90/180/270 degrees etc. my device rotates just in 3 directions ;)

thanx

A few comments & questions from a noob

G'day all, great to finally find a forum about my new device.

I purchased mine from Merimobiles about 4 weeks ago.

Shipped with 0613 FW, runs pretty stable, full market, Gapps etc.

Problems:

Clock wont keep time when turned off

Wont wake from sleep unless it's connected to AC or USB

Calendar won't sync

Apps disappear when moved to SD. This is a problem cos I'm running out of space!

Skype works perfectly but no video option.

Thanks to this forum I've got my HDMI out working and I know I'm not alone with my issues, except maybe the clock thing.

I'm looking forward to following this forum to see if a truly fix all FW gets released. If anyone can offer any suggestion for my issues that would be cool.

This is probably a classic noob question but what are you all trying to achieve? I can see _fun is doing some work with custom roms or something. Are you trying to get better battery life by getting rid of the 'Mobile standby' thing that is apparently draining the battery? I'm happy to be enlightened on this!

Thanks everyone!
[Android Q&A, Help & Troubleshooting] tinybeetle:
Hi Rusty,

I've noticed a few other people who have the 0613 fw having issues. The latest out there is 0616. The links are in this forum. It is also labeled 07 something, but is 0616 once you install it. I would start there, with the newer FW.

There is a continually wakeup-issue with the 0616. I fixed that by installing "Soft Locker" from the app-store. It keeps the device from going to deep-sleep, thus eliminating the need for wake-up.

I'm not experiencing the clock thing. I never could get it to sync with the network, so I turned that option off and set the time and zone manually. It keeps time fine for me, off or on.

Not waking from sleep issue is not happening with mine.

I sync my calendar to my corporate exchange account. It works fine. I use Jorte as the on-device calendar.

The corrupting/disappearing app thing is quite annoyingly present on mine. There doesn't seem to be much rhyme or reason to it. If you look in settings, managed apps, you'll usually find them there, but with the canonical name instead of the friendly name. That means the app has been corrupted. I've had to uninstall the corrupt one at that point and re-install.

Root your device, there is a pretty good link to how here. It is translated from Japanese. I followed it with success three times now on 3 different fw versions. Once rooted, install Titanium backup (be sure to tell it to not compress the backups in the options, it has trouble restoring it's own backup if they are compressed) and set it to automatically backup your device to the SD card. That way if an app corrupts, you can hopefully restore it.

Also, once rooted you can remove (rename) the phone.apk and the telephonyprovider.apk and get that battery sucker shut down.

I've noticed that if I turn off WiFi prior to changing locations, the device is much more consistent in waking up and connecting the WiFi again at the new location.

Cheers!
[Android Q&A, Help & Troubleshooting] quebbles:
i had some problems with dissappearing apps in the beginning. at some point the internal sdcard was corrupted and couldnt be repaired automatically making it read only. After i formatted the card using non-fat option instead of fat it has been working fine without probs. i did the format from the device itself. also never use the off switch, but use the os power down feature instead (pull down the off switch, holding it until the power down dialog shows)
[Android Q&A, Help & Troubleshooting] tinybeetle:
Quebbles, how did you do the NTFS format? All I see is an option to "erase card". Sometimes you don't have a choice and must power-off if the device is stuck. But, I suspect that during those times nothing is actively reading or writing to storage anyway.
[Android Q&A, Help & Troubleshooting] quebbles:
yea sorry dont remember if it is ntfs. but if you do the erase you get another option besides fat

i think the fat repair tool is not that good
[Android Q&A, Help & Troubleshooting] quebbles:
i just checked: for the nand you can choose ntfs or fat32 if you choose erase
[Android Q&A, Help & Troubleshooting] tinybeetle:
Thanks! I'll have to remember that next time I upgrade the FW. I don't feel like reloading my stuff to the NAND right now. :D

just flashed it via FWDN_V7_v2.13 - works on the ly-f521 :)

they changed the lcd-density to 240. rooting works like before (SuperOneClickv1.9.5-ShortFuse)

the axis of the sensor are still mirrored (grrrr)

the recovery is accessable - but still no way to move up and down, means still worthless...still no easy way to flash cwm. it dont flashes the update.zip automatically (tested both, nand and sdcard).

BUT...ON PHONE I VE BOUT 597 MB FREE (at least superbox app2sd means that)

re to "597MB FREE", size of MTD is 1GB now? internal NAND area is shrinked?

No joy with FW update or root

I've been following the up date video very carefully but when I try to boot it, it does not get recognised. I have notice that since about day 1 I have not been able to connect to my computer (mac) in debugging mode. I know it worked once but will not mount. Tried on my PC partition (XP) and on my mates PC (XP) but nada. So this makes me think maybe I have a problem with my NAND. I can copy files to it (over wifi with ES). If I reformat the NAND will I loose the FW too?

I also tried to root using superoneclick I couldn't even get that to open on my PC.

FAIL!

At least I haven't bricked it yet!

My home screen wont rotate but Kindle will (sort of) and floating image definitely works just fine. I wonder if that has anything to do with floating images setting that allows a 'forced screen rotation' which I have set to 90 degrees.

[Android Q&A, Help & Troubleshooting] palermo123:
sounds nice :)

but the axis-problem is still anoying. gsensor x + y are still mirrored (z, i dont know). any idea how to fix that?

on homescreen, i lost the main-portrait-mode (power and 3 buttons top left). rotating in the other 3 directions is working. before upgrading another direction didnt work...funny.

there are some settings to fix that (at least on my htc hd2), but i cant remember the app.

and bad news - still wake ups...(every 5 mins. or so). renamed phone.apk and telephonyprovider.apk didnt change that...maybe it helps the battery.

i ll give it another 14 days - if there is no better os i ll buy a galaxy tab... ;)

Merimobiles has put up the 0720 firmware for download at a yousendit link.

Yeah maybe 0720 is a major release if Merimobiles have it. If you flash it bro let us know how it goes.

My screen rotation came back after a few days and seems to work just fine.

As I said earlier I couldn't get my device to mount. I might un mount & re mount the NAND as this is mentioned on a few forums as a way to get your drives to mount. Do you know if there is any risks associated with this?

[Android Q&A, Help & Troubleshooting] tinybeetle:
Jonnis, if you read the entire thread you'll see that the native video codecs that the tablet comes with are NOT part of the CM7 package at this point in time. Thus, if you want the video capability (and a few other things that the tablet comes with from the manufacturer) you need to stick with the officially released firmware versions. If you want to experiment, and contribute to the CM7 development, then run that version.

Root MID TCC8803 Cortex A8 with android 2.3.3 (LY-F521)

First of all, please exsuse my english, I'm about to destroy the language.

I'm trying to root my tablet, it's a MID TCC8803 Cortex A8 with android 2.3.3, somewhere in the user manual says LY-F521.

Tried downloading Gingerbreak on the tablet and followed the instructions, no go.

Tried SuperOneclick, first I got stuck on Waiting for Device until I managed to install the drivers. After I passed that stage, I got the message "your device is already appears to be rooted", but I still cannot access the "/data/data" folder, and when I verify with Root Checker says I have no root access but I do have Busy Box installed. So I click continue with SuperOneclick but hangs on Step #6 (that is, step #5 is completed and hangs during step #6). Tried exploits "Auto" and "Gingerbreak" with similar results.

I just need permanent read and write access on the "/data/data" folder, I don't want to do anything else since I don't want to break anything or brick my tablet. Anyone can help me to just get root access and nothing more?

Thanks!
[Android Q&A, Help & Troubleshooting] tinybeetle:
You need to use the ADB to delete something. There isn't enough room to hold the required gingerbreak files. There is a link to a Japanese (translated) siite that shows exactly how to do this, step-by-step. Look back through some of my posts on this thread to find the link.

The information (step-by-step) is located here.

Thanks tinybeetle!

This is where I am now: I had given up trying to root this tablet, and I tried a FW upgrade to solve some minor issues using this: http://www.youtube.com/watch?v=98fGgLPRAt4&feature=player_embedded#

but now it won't boot! I just see the fish and the bubbles but like in a 16 bits resolution, with colors all messed up, and doesn't do anything else. The whole procedure didn't report any issues but now I'm stuck with a "fail safe mode" or something like that.

So I tried to do this: http://xdaforums.com/showthread.php?t=1119778, but I didn't get anywhere, 'cause if I'm pressing the back button and I keep holding the power switch down (I don't have a power button, it's a sliding switch like it's shown in the video) keeps powered off, and if I hold the back button and just slide the power switch releasing it, nothing happens either. Same thing with home button and the other one.

So I went back to the "FWDN_V7_v2.13.exe" and started to try roms with no luck (once I got a chinese splash screen instead of the messed up fish, but by the end of the process the tablet started to reboot over and over again).

Can please someone help me to go back where I started? That is, with a tablet with no root access and with some minor issues. If you can point me to the right rom that I can load with FWDN_V7_v2.13.exe will be great! Also will be nice to be able to recovery boot, so I can try this: http://xdaforums.com/showthread.php?t=1119778.

Here's what I know about the tablet:

MID TCC8803 Cortex A8 with android 2.3.3, somewhere in the user manual says LY-F521, and in the chinese part of that manual also says EM72/EM73, surrounded by characters that I don't understand

The only thing I see different on the one at Deal Extreme is the screen, and that, in my opinion, is the entire reason to want the device. With an 800x480 screen, it is just another no-name device. With the 1024x600 screen it is an amazing multimedia powerhouse.
