hello, same problem, same description, no support answer from erisin. I change my car android radio. Probably a WinCE problem but the support from erinsin doesn't exist, no rom links, nothing, nothing...nothing from them.
[Android Q&A, Help & Troubleshooting] mike351:
Yeah i'm experiencing the same issue. Their technical support, which used to be good, is now worthless. I'll keep trying though. I really think this is due to the base OS becoming corrupt.

erisin es8935a firmware main unit

I have purchased a CVJY-C225 chinavasion car radio for a week that is equal to ERISIN ES8935A,

I still do not install it in the car,

the problems are:

1) when I plug in the tablet with android on the main unit, the tablet goes off and the Android 4.04 operating system does not start but so i can not use the 2din the main unit to say

2) There is the dtv antenna but there is no icon as I see on the manual

3) There is no duplication of the pad pad on screen is the Android Robot

Does anyone have this my problem?

Do I have to put a firmware / software where the missing icons appear?

Where do I find the firmware for the main unit?

thank you
[Android Q&A, Help & Troubleshooting] Parastie:
Good to know.

Also, I'm trying to recover one dead EM73. Shorting pin 7 and 8 after disconnecting battery seems to do something, but FWDN says that there is not BOOT director. I try to flash lk.rom from the EM73 download, but nothing seems to happen.

FWDN says only,

UBS(USB Boot Supporter) Load Complete! - (0sec 01)

BOOT Load Complete! - (0sec 39)

Then there's a grey bar and nothing... :(
[Android Q&A, Help & Troubleshooting] Jrockz:
Parastie, try this file I'm going to send you. It is the latest firmware for your tablet. I have the same one that you do. em73 with resistive panel. try checking all 3 files in fwdn and see if that does anything.

[Android Q&A, Help & Troubleshooting] Parastie:
Cool, I'll check it in just a minute. I finally got a firmware to write to the tablet so it's actually turning on the first time in days! I'm not exactly sure what I did, but suddenly FDWN shows the nand correctly and wrote!

Please note, the links from _fun, the touch screen doesn't work on our devices. LoL
[Android Q&A, Help & Troubleshooting] Parastie:
Ok, well if i'm remembering what I did correctly:

1. Have FWDN setup FIRST: Up, loading you lk.rom and img file. I also had an .fai file that I had backed up before i started screwing with everything.

2. Short pin 7 and 8 on the NAND flash, and hold the power button.

3. WAIT while FWDN tool does its things. DO NOT let go of power or the short.

4. When FWDN shows the NAND flash info, then you can release power and short.

5. Click start, and away you go!

At least that's what I think I did..
[Android Q&A, Help & Troubleshooting] Parastie:
Okay, using this file I'm up and running however the video playback is not as good as my stock build. I have a backup unit that I'm going to push only clockwork to so I can get a firmware backup.

Hey _fun, your build of EM73-recovery-signed worked like a charm! Installed it using standard update procedures. Now i'm cooking with gas :)
[Android Q&A, Help & Troubleshooting] Parastie:

I've unbricked a dead tablet, plus Clockwork is running! it's great :) Now I just gotta work on getting root and maybe fixing some glitches like the accelerometer and I'll be set :)

Is it possible to create an update.zip that only includes su and superuser.apk?
[Android Q&A, Help & Troubleshooting] Jrockz:
This version of super oneclick works for me. Give it a shot.

this zip didn't work?
[Android Q&A, Help & Troubleshooting] fun_:
just FYI,

in USB boot mode(by short pinb 7-8), currently loaded & selected bootloader(lk.rom) on FWDN.exe is uploaded into device's RAM via USB.

it is not flashed into NAND yet, so if currently selected lk.rom doesn't work well, disconnect & reset & retry USB boot again with another lk.rom.

if it works well, flash lk.rom once, then lk.rom will be loaded from NAND next boot.
[Android Q&A, Help & Troubleshooting] Parastie:
I'm trying that now. I'll get back to you in a few minutes.

Alright! Root appears to be working now! Thanks again. Man I feel like a complete moron now, I've been trying to get this stuff to work for weeks now and you guys do it all in a single day! :)
[Android Q&A, Help & Troubleshooting] fun_:
sounds good.

probably clockworkmod recovery for capacitive EM73 has a issue for touchscreen on resistive EM73, but touchscreen isn't used in clockworkmod, it's OK for now ;)

if you want, I can make clockworkmod and cyanogenmod(w/ calib app) with kernel for resistive EM73. probably you can make 2.3.3 custom ROM with resistive kernel & calib app from resistive ROM, and it may be better :)
[Android Q&A, Help & Troubleshooting] Parastie:
I was thinking about that. I'd also really like a cifs.ko module. I'm considering trying this module someone built for the Galaxy Tab. It wouldn't hurt to get give it a try. I can make a CWM backup of my firmware and post it. I'm not sure how to do a 'dump' of a firmware.

EDIT

cifs file for galaxy tab didn't work. :)
[Android Q&A, Help & Troubleshooting] Jrockz:
Parastie,

Did you root the tablet or do you want me to resend the superoneclick file?
[Android Q&A, Help & Troubleshooting] Parastie:
I got it rooted using the links from _fun. I could never get one click to work.
[Android Q&A, Help & Troubleshooting] Jrockz:
Do you have SDK installed on your system? if not, that maybe the issue. Well it's all good. you got it rooted anyways. By the way, can you do me favor and open up google.com in your browser and tell me if it force closes? thanks
[Android Q&A, Help & Troubleshooting] Parastie:
It is force closing, that's really odd. I know it didn't do that yesterday. Maybe it's a glitch today? Dolphin HD doesn't crash.
[Android Q&A, Help & Troubleshooting] Jrockz:
You went to google.com on dolphin HD and it doesn't crash? All browsers for me crash when i try going on google mobile site. I think FUN said he would try do make a work around for this ;). This is my only huge issue with the tablet. Other than that, it's pretty solid.
[Android Q&A, Help & Troubleshooting] Parastie:
Well I have HD set to mimic a desktop setup. I know that the mobile google worked earlier, maybe not today but certainly yesterday. It's very odd behaviour. I wonder why it does that. Does it crash with Firefox? It's a different engine, it shouldn't crash. If it is, it's gotta be something it's asking the tablet for that the tablet doesn't have. Like location or something similar.
[Android Q&A, Help & Troubleshooting] Jrockz:
Yea, the issue definitely has to do with google trying to get a location and when it doesn't it closes down....for some reason i cannot load firefox on my tablet.
[Android Q&A, Help & Troubleshooting] Parastie:
So, lets say I wanted to use the 2.3.3 firmware i've got downloaded that works with a capacitive tablet. What's the easiest way for me to exchange my tablet's kernal and install the calibration tool? The Android Kitchen maybe?
[Android Q&A, Help & Troubleshooting] Jrockz:
When you were on 2.3.3, you didn't have the browser issue?
[Android Q&A, Help & Troubleshooting] Parastie:
My touch screen didn't work, so I didn't get a chance to try.
[Android Q&A, Help & Troubleshooting] fun_:
try this one

http://androtab.info/files/tcc8803/rom/EM73-SX-2.3.3.zip

kernel from post#62 + system.img from EM73 2.3.3 ROM + Calibration-EM73-SX8651.apk + my clockworkmod for EM73.

probably /data/data/touchscreen.calibration/files/pointercal is created after calibration...
[Android Q&A, Help & Troubleshooting] Parastie:
Excellent, I'm downloading now. I'll let you know how it goes.

Can you tell me how to turn a nandroid backup to a .zip so I can send you my build? I think there might be some differences in the kernal from what I have and what JRock has. When I used his build, HD video playback from micoSD was not smooth, while with my build it works great.

EDIT:

Firmware is working great so far! HD video is good, and I think the accelerometer is working a little better. I'm going to do a few more tests and I'll get back to you. Thanks very much!

EDIT2:

I can't really see a difference between 2.3.1 and 2.3.3. I'm going back to my clockwork backup for now. Accelerometer is still an issue and I'm wondering now if it isn't the hardware. Anyone else have a problem with it? It's almost like the X and Y axis are swapped.
[Android Q&A, Help & Troubleshooting] fun_:
sorry, what kind of zip? just zip your *.img isn't enough?

and you want EM73 2.3.3 ROM with your kernel in your backup, right?

then, please send me boot.img.

X-Y swap is very common on cheap chinese tablets. (how wrong is different each product ;)

I added some hack in my CM7. ROM from chinese factory also did some hack.

but if accelerometer is right(with or without hack), some app still wrong on tablet. default orientation (0 degree) is landscape on most tablet, but some app think "0 degree is portrait!". recently some games have X-Y swap switch in settings but still some bad apps are exist.
[Android Q&A, Help & Troubleshooting] Parastie:
The problem with the accelerometer is very strange. For example, if you download Labrynth and go into the settings, it has bubble meters that obviously show that the X and Y axis are swapped. However, if you use another 'level meter' app (an app to see if the tablet/phone is setting level) then X and Y are correct. I'm really not sure why that is.

In your other thread you had a few lines of code for 'sensor.accelerometer.x' to be placed in the build.prop file. I attempted this to see if it would help, but it didn't make any difference in any of the programs I tried.

I'll post my boot.img file in a awhile. I'm going to try your 2.3.3 again. It worked okay, but I'll try erasing my firmware first and then try. I've got Titanium Backup working now, so it shouldn't take long to reload my apps.

One last question, just to see if it would even boot, do you think you could take the system.img file from the Nook Color Honeycomb build and pair it with the boot.img from your resistive 2.3.3 rom? If you have time, please try. You will have to set the ro.sf.lcd_density to 133 in build.prop, instead of the default 200 for it to work properly.
[Android Q&A, Help & Troubleshooting] Parastie:
Back to my original 2.3.1 with root. I can't decide if the 2.3.3 is better or not. Accelerometer is no better and I'd have to use it for awhile to see if the battery life is improved.

I got an email from Emdoor, I'm hoping to get some firmware from them directly. I'll let you know how that goes.
[Android Q&A, Help & Troubleshooting] Jrockz:
Fun, this is a good firmware for this tablet. It actually feels quicker and there is no issue with the web browser...out of curiosity, is there anyway to be able to cook a firmware like that for the other tablet i have?
[Android Q&A, Help & Troubleshooting] Parastie:
Hey Jrockz, do you really think it's better? The only reason I haven't stuck with it is the time consuming problem of getting everything setup again. Titanium Backup is not working as perfectly as I would like. However, if you think it's running better, I'll give it a thorough go.

BTW, does your screen go off-and-on while locked?
[Android Q&A, Help & Troubleshooting] fun_:
no X-Y swap setting in Labrynth? then, it's one of "bad app" ;)

build.prop lines enable/disable my small change in framework. it doesn't work with other ROMs (maybe they have another hack and no visible switch to on/off)

some tablet has "game mode". I think it swaps X-Y internally for "bad app" and enable another hack for correct orientation on "good app" ;)

my CM7 hack doesn't have such a system wide "game mode". probably you can do by flipping flip_xy and invert_x values (only) when running "bad app".

I can't decide which is better, 2.3.1 and 2.3.3. generally people want newer one :)

G sensor worked fine on your 2.3.1 ant not fine on 2.3.3? then, please send me system.img too. I'll make new image with your 2.3.1 kernel and sensors module. I used sensors module from EM73 and it might be wrong.

(I'm not sure because G sensor hack can do any place in kernel, in sensors, and in frameworks)

for honeycomb, I'll not do that work... probably they used files from 3.x SDK emulator or another 3.x talbet. I did such work on telechips tablet when 2.3 SDK released so maybe I can do it, but I don't like it. if something not worked, fixing it without source is difficult, or impossible :(

(at least it takes time)
[Android Q&A, Help & Troubleshooting] Parastie:
On the G-sensor, it doesn't work on 2.3.1 any better then in 2.3.3. So I'm not sure which is better either. I keep going back because I don't want to spend the time setting it back up like i have my 2.3.1 firmware.

As for Honeycomb, I understand if you don't want to try. I know it's very difficult otherwise we'd have ports all over the place. I was really just curious if it would even boot. We can always wait for Ice Cream Sandwich, which is suppose to be open when it comes out. :)

EDIT: The first firmware you linked to said it fixed G-sensor problems. It was dated May 06, and is probably 2.3.1. Could you build that with resistive screen kernal? I'll test it for G-sensor problems.
[Android Q&A, Help & Troubleshooting] fun_:
I don't know which tab you have ;)

you want 2.3.3 ROM for your LY-F521 like tab? I guess LY-F521 2.3.3 ROM(other than lk.rom) may work... did you tried?

if it didn't work then I'll make image with your LY-F521 like tab(please give name to it) kernel + LY-F521 2.3.3 ROM.

but I'm not rom cooker.(I have no time for it) I never modify other part in 2.3.3 ROM to imporove something. if you(not only jrockz) want cook ROM, you should learn how to.

Something to try:

You guys should try changing the DPI to 150 or lower, and then install something like GO Launcher or Launcher Pro. It makes the devices seem larger, and more useful.

(it is incomplete e.g. no hw video decode so I don't recommend for such purpose)
[Android Q&A, Help & Troubleshooting] Parastie:
Sure! It'll be worth playing with for awhile. Sadly, I have Windows 7 64bit on my main computer, which has so far prevented me from installing the ADB drivers so I can't just push contacts and calendar updates. But if you do a CM7, maybe I can use Titanium Backup to repair those issues.
[Android Q&A, Help & Troubleshooting] Jrockz:
There's adb drivers for 64bit. I'm on 64bit too.
[Android Q&A, Help & Troubleshooting] Parastie:
The Motorola driver is suppose to work, but when I tried to install it Windows 7 blocked the install. Now when I try to do ADB, the tablet doesn't show up.

It's a shame the CM7 gapps file doesn't work. :( It just makes thing worse, killing Gmail and Market.
[Android Q&A, Help & Troubleshooting] fun_:
give me your boot.img and /system/lib/hw/sensors.tcc88xx.so. I'll add your files into my batch build script to build CM7 regularly.
[Android Q&A, Help & Troubleshooting] Parastie:
It'll take me a bit, I have a slow connection. I'm also seeing if I can move everything to the 2.3.3 build. What's the best way to send you those files anyway?

EDIT:

Okay, I've got 2.3.3 up and running and everything seems okay. I can't say it's better then 2.3.1 but I'll give a few days. One thing of note, WikiDroy does not work and that's a huge disappointment. It's really one of my favorite apps. Hey _fun, can you use the firmware from post 3 with the resistive kernal? I'd really like to see how well it works.

BTW, what programs are you using to make these rom builds? I know you enjoy the work, but I feel bad having only you doing it.
[Android Q&A, Help & Troubleshooting] fun_:
check PM. I'll make your kernel + Gpad702 2.3.1 ROM for you but give me some time.

about tools and procedure,

EM73_SIS_GC2M root or rom?

Hello I have just bought an EM73 7" capacitive screen 800x480, it has a 2m pixel camera.

Here is the "About phone" details:

Model number: EM73_SIS_GC2M

Android version; 2.3.3

Kernel version: 2.6.35.7

Build number EM73_SIS_GC2M 20110530

This should make sense with your analysis.

It works okay but the axis are definitely switched from x to y (I tried to use labyrinth not possible to switch axis)

Anyone have any Ideas?

Also the camera works but doesn't appear to have a webcam function? Can't use skype in fact it keeps forcing close as soon as I try to open it. Have uninstalled it for now. I really wanted to use this tablet for skype videocalls, is there anyway or anyone got a rom which will allow video chat with this camera?

Would love to root this tablet or maybe try a different ROM. I've only had it a few days so would need to be sure the rom was for this model. Can't aford to brick it.

If anyone can suggest a rom to try or a good root how to, it would be greatly appreciated.

Well, you have the latest firmware available, 2.3.3. I advice downloading the clockwork mod files from post 6, and the su package from here: http://xdaforums.com/showthread.php?t=682828

Once you've installed clockwork, install the su zip package from clockwork. Then, once you've rebooted you should go to market and update superuser and let it update the su binary. Then install Busybox from market.

We're all really just waiting for _fun to get his EM73 so we can have some really nice firmwares. The accelerometer problems seems to be universal among Telechip tablets. I just hope it's a firmware issue and not a hardware problem.

I don't know accelerometer is really wrong on stock rom. if home screen works fine and only some apps are wrong, then just some apps may be wrong.

accelerometer issue is not telechips specific problem. it depend on how G sensor is assembled, how kernel is coded, how sensors.so is coded... and ROM maker really think about fix this issue or not. maybe chinese cheap tablet factory don't care about issues and they don't think "we must provide updated rom asap to all customers!!!" ;) (just sell many tablet with or without issues and get more $$$!!!)

by the way, complete procedure to backup stock rom is,

1. get temporary root (permanent root modify /system so should not be used if you really want to make non-modified backup)

2. backup stock recovery

3. install clockworkmod

4. reboot into clockworkmod

5. make backup (only boot.img and system.img are needed)

system.img made by clockworkmod can't be flashed by fastboot. (restore by clockworkmod is ok)

if you want to use this system.img with fastboot, you need to convert pagesize 2k -> 4k.
