please tell me your /proc/mtd (1 report is enough on 1 tablet). it seems 150MB /system may be full (esp. 8k pagesize NAND). I need to reduce /system ;)
[Miscellaneous Android Development] hirokishi:
Hi fun

Thanks for your great works.

I installed EM51 recovery ver.0614.

The following is my report

･The touchscreen works fine.

･Sound & Mic is working.

･USB mouse is not working.(The device freezes.)

･USB keyboard is working.

･Youtube is working but sound only(ver.0612 worked fine.)

･Can't recover after sleep & screen off.

Hi fun these are stock images posted onto the scrolltablet forum by our members not me personally

Thay are there to help recover bricked scrolls

They are all from new untouched scrolls
[Miscellaneous Android Development] fun_:
please point me that thread/post on scrolltabletforum

is it this one?:

[Miscellaneous Android Development] fun_:
thanks. I downloaded these "1.02" images.

I found this link
[Miscellaneous Android Development] fun_:
thank you for your report. reasonable results.

suspend/resume issue is common thing on tablets made by Emdoor. if you have 2.2/2.3 ROM for EM51, please give me ;)
[Miscellaneous Android Development] fun_:
now I got Scroll 7" 1.02s real boot.img now. system.img is useless but it's ok. I think 1.02 system(and boot.img, maybe) will work just changing pagesize ;)

I'll make CM7 fot these on next build.
[Miscellaneous Android Development] will8578:
thank you very very much for all your hard work
[Miscellaneous Android Development] Mitred:
seems i posted wrong link last night sorry for that must have been half asleep

well spotted fun

update to scroll cm7 managed to tether to my phone with barnacle and wifi tether

could not do that on stock rom exellent stuff

my scroll can now go out and see the world

Not Working

scroll has second usb called usbhost

on original OS it showed as "scsi"

did you rename this to "mnt/usb" plug usbstick in it shows for 30seconds (you can see the files on a usb stick)then the light on the stick goes off and you cant see the files also no way to safely unmount just have to pull out then have to reboot scroll to make usable again

HDMI out, not working cant find any settings for this!

on scroll firmware in settings/display had two options "HDMI" or "NONE".

"HDMI" would send the signal to the hdmi socket and "NONE" would send it to the scroll screen

I am shure if you had it set to HDMI and tried to watch video you got sound and no picture (which is what we got now?? until you changed to none

any thoughts on this:confused:
[Miscellaneous Android Development] Squel:
fun_ i sent you pw with links to my files boot.img and system.img
[Miscellaneous Android Development] slatis:
Hey fun tnks for your work again, sorry to bother you but just until today i realize that the screen is inverted when you switch to landscape orientation. Is there any possibility to fix it?

Tnks again, and keep up your great work!!!

Update: Nvm I fixed uncommenting the inverted Y axis line.
[Miscellaneous Android Development] fun_:
please clarify

1. you are using M701 GB rom installed and no-HY model

2. you are not using ro.sf.rotation and no change added to my CM7

then, I'll change my code too. probably you are first user to check it... (I don't have M701)

if someone has M701, please check landscape and "sensor.accelerometer.invert_y=1" is required or not.
[Miscellaneous Android Development] slatis:
Yeap I'm using the m701 GB rom, and I'm using your cm7 with no change. I have just changed the "sensor.accelerometer.invert_y=1" to commented.

Btw another issue I have found is that the multitouch is not working that well, actually is a pain in the neck to make my tablet recognize pinch zoom gestures.
[Miscellaneous Android Development] fun_:
oh. Is multitouch working on GB ROM from Haipad?

I made M701 CM7 from Kyros7015(singletouch) repo... maybe I need to change some line in my file ;)

I'll change it too.
[Miscellaneous Android Development] fun_:
thanks. system.img is broken(need to use another tool to dump) but ok it seems made by CBS... probably haipad files can be used like many other tablets :)

EDIT:

I confirmed your image and custom rom posted on slatedroid have same kernel and same build id.

Linux version 2.6.29 (cbsmbg@CBServer) (gcc version 4.3.1 (GCC) ) #232 Tue Jan 18 16:32:47 CST 2011
telechips_tcc8900_us-eng 2.1-update1 ECLAIR eng.cbsmbg.20101213.203949 test-keys

I think GOCLEVER TAB T73 is same as Dropad D10... anyway, I'll make CM7 for these tabs
[Miscellaneous Android Development] will8578:
hello fun this is from eddie on the scroll forums:

Linux version 2.6.29 (root@localhost.localdomain) (gcc version 4.3.1 (GCC) ) #172 Fri Jan 14 02:24:02 CST 2011 - thats for scroll 7 1.02 FW, thanks
[Miscellaneous Android Development] Squel:
Thx fun_.

Already can not wait CM7 to my T73 :)

What tool do I use to dump system.img
[Miscellaneous Android Development] fun_:
http://androtab.info/files/tcc8902/cm7/20110619/

D10-8K for Dropad D10, GOCLEVER TAB T73

SCROLL7-8K for Scroll 7" 1.02s

SCROLL8-16K for Scroll 8"

http://androtab.info/files/tcc8803/cm7/20110619/

EM73-8K for EM73 8k pagesize (v2)

EM73-SX for EM73 resistive

for capacitive screen, please cancel(back) Calibration app, but if you are using Dropad D10, you need to complete Calibration app and reboot after calibration.

if update from previous, please check Settings -> CM settings -> Display -> rotation

non-live wallpapers and Magic Smoke live wallpaper, audio files, themes, and extra dictionaries for LatinIME are removed to reduce /system. please tell me your /proc/mtd.

I changed some bits for accelerometer and touchscreen on M701.

I'll update OP/site/this post later.
[Miscellaneous Android Development] will8578:
Fun, i see you have posted a scroll 7 and a scroll 7 8k, whats the difference? thanks
[Miscellaneous Android Development] Squel:
Tell me how to dump system.img, becouse I need to have a orginal backup.
[Miscellaneous Android Development] fun_:
install recovery.zip(put it on /sdcard/update.zip) from stock recovery, reboot into recovery again, make bacakup from clockworkmod recovery.

you already backup stock recovery so it should be ok to install clockworkmod recovery on recovery partition.

working after flashing new boot. no touchscreen though... wake/resume works
[Miscellaneous Android Development] dustinhayes93:
Thats weird that it would work in the GB version but not the 2.1 version.... Hmmm :confused:
[Miscellaneous Android Development] fun_:
I guess he just said he don't know any way. here is not the place to talk such a non-technical thing.

we are working with technical background. we don't know our project will get valuable result. but all process is valuable (at least for me), it's enough reason to do this project. if you don't think to join this project is valuable, no one enforce you to join this project.

thank you for your cooperation.
[Miscellaneous Android Development] fun_:
thanks. it seems recorded error in logcat is reasonable. (I fixed it in boot.img/new cyanogen.zip)

hankm24,

I'm not sure why adb didn't work on your tablet. did you flash CM7 for GB ROM? file name must be cyanogen_kyros7015-ota-eng.fun.zip (for GB ROM installed unit) not cyanogen_tcc8902-ota-eng.fun.zip (for non-GB ROM).
[Miscellaneous Android Development] fun_:
good news!!! if you can, please try to control with mouse or keyboard and test another hardware e.g. audio, wifi, etc...

I'll add touchscreen calibration at some time(need time) because it is required for my tablet :)

by the way, touchscreem doesn't work at all? or just not calibrated?
[Miscellaneous Android Development] fun_:
sorry deleted
[Miscellaneous Android Development] hankm24:
Okay got you CM7 working on 2.3 img but no touch screen support .

I'll try to get it to work and post how to so i can save you some time.

I also realized how to add HDMI out really easy im going to send you the HDMI.lib to your email and put it in your new CM7 build already added it to mine works fine.

Also I have the OMX files for GingerBread to get video working!
[Miscellaneous Android Development] fun_:
thanks. I'll push my new files to build CM7 for GB ROM into github soon.

by the way, your OMX files work only on GB ROM tablets? or non-GB ROM(kernel for 2.1 ROM) too?

EDIT:

if these files are same as in Gpad701 GB ROM, no need to send file itself, just tell me.

and sorry, by some reason, I can't use the file which is not released in public. I only use source or binary that anyone can get from the net. (I don't care someone make other CM7 based on my CM7 with changes)
[Miscellaneous Android Development] dustinhayes93:
Touchscreen DOES work... its just not calibrated. And also, on this GB version the accelerometer is a little weird, cant make up its mind.
[Miscellaneous Android Development] fun_:
thanks. sounds good, because we don't need to find secret "touchscreen enable switch" :)

for accelerometer, how weird? please try to change following properties by setprop command

sensor.accelerometer.flip_xy=1
sensor.accelerometer.invert_x=1
sensor.accelerometer.invert_y=1
sensor.accelerometer.invert_z=1

please start all 0. it may need accelerometer off/on in settings after prop change.
[Miscellaneous Android Development] fun_:
about touchscreen calibration, there is tslib related files in Gpad701 GB ROM.

it will make pointercal, and pointercal seems to be handled in libui.

some tslib source for android is exist e.g. android-x86 git repo.
[Miscellaneous Android Development] stoned99:
Well, it doesn't work me. I tried unlocking the tablet from everywhere on the screen and no changes... I don't know the difference between me and dustinhayes... that's weird...

I didn't wipe before installing the rom, maybe it would have fixed it?

btw I have the 7015A version not the 7015. Another thing, it seems to reboot every like 10 minutes... Haven't ran logcat yet to verify what's causing it though...
[Miscellaneous Android Development] dustinhayes93:
O have a 7015A and i flashed the oem GB rom and went straight to this CM7... That could be the diffrence. idk. :confused:

And i cant get mine to shut off now. Any command to use in adb to shutdown? =o
[Miscellaneous Android Development] fun_:
oops. really weird.

please wipe data/factory reset when installing from non-CM7 ROM. it should not need to wipe when updating newer cyanogen.zip from older cyanogen.zip.

--

pushed CM7 files for GB ROM.

https://github.com/naobsd/cm_device_coby_kyros7015

use it freely :)

there is many common files in cm_device_coby_kyros7015 and cm_device_telechips_tcc8902. I'll restructure these repo in future.
[Miscellaneous Android Development] stoned99:
Also went from oem GB to CM7 then flashed fixed boot.img

idk any command that can shutdown in adb... sorry
[Miscellaneous Android Development] dustinhayes93:
I also put my boot.img in the .zip idk if that would change anything :confused:
[Miscellaneous Android Development] stoned99:
nope since I flashed it in fastboot afterwards so we should have the same thing...
[Miscellaneous Android Development] fun_:
what happen when you select power off from power menu?
[Miscellaneous Android Development] dustinhayes93:
Touchscreens not calibrated bud ;} And i cant find my usb host thingy for keyboard XD

And i tried the setprop stuff for the accelerometer and its still fliped 0.o
[Miscellaneous Android Development] fun_:
aaaaahhhhhhh. I see!

hmm I want to hear how wrong, but I know such conversation is(was) very very diffcult...

please find correct combination :)
[Miscellaneous Android Development] fun_:
oops. FWDN image flash all boot/system/recovery image at once, you erased stock image...

and sorry, image for D10 was wrong. I'll make correct image soon.

EDIT:

uploaded as D10-8K
[Miscellaneous Android Development] Squel:
ok. no problem, I'll wait

on this new image D10-8K tablet flashed and now is booting new system :)

Thx fun_

I have problem witch screen, taskbaar in on the down of screen and touch is inverted
[Miscellaneous Android Development] interfac9:
I have the exact same problem. Anyone find a fix?
[Miscellaneous Android Development] Squel:
Do you have dropad or goclever t73 ?
[Miscellaneous Android Development] interfac9:
Neither. Phecda P7
[Miscellaneous Android Development] slatis:
If you go to cyanogenmod settings, there you'll find an option to change the notification bar to the top; but the new position is at the bottom of the screen and I recommend you to leave it as it is.
[Miscellaneous Android Development] interfac9:
The bar is not really the major issue. My problem is that if I try to select anything on the screen the touch focus is on the opposite side. I cant open the drawer or move anything unless i touch its opposite position.
[Miscellaneous Android Development] interfac9:
Calibration at first startup goes as it should though.
[Miscellaneous Android Development] fun_:
if you got calibration issue on HSG devices, please redo calibration. if still wrong, please use old pointercal from eclair rom.
[Miscellaneous Android Development] fun_:
I thought Dropad D10 has capacitive screen. GCT T73 has capacitive screen too?

if it's capacitive and you cancelled calibration app, please try calibration.
[Miscellaneous Android Development] pbassjunk:
Restart the tablet. Mine does the same thing on its first run after the calibration. When it restarts, works fine.
[Miscellaneous Android Development] fun_:
ah, reboot is needed. at this time it's a part of the install procedure I wrote :)
[Miscellaneous Android Development] Mitred:
hi fun thanks for making the 1.02s and 8" roms for scroll(are the gapps pre loaded or should they be flashed before reboot)

i have tried to simplify the how to thread on scroll forum as people were getting confused hope it meets your approval

(you are more tech speak on xda we are more simple speak on scroll forum:) )

maybe we'll get some more testers now

the 1.02 rom is working fine for me with the rotateD app

was gonna flash back to stock to look for the code for HDMI out (any idea where i should be looking)

on the stock rom in settings/display you could choose between HDMI or NONE if you chose HDMI the screen would be blank for video but you had sound (could this be the problem with no video on cm7(we have sound)

and also we have lost the usb host socket(2nd usb on scroll) if you put a usb stick in it only shows for 30 secs

then the light goes off and cant read. then have to reboot to get rid of ongoing unmount
[Miscellaneous Android Development] fun_:
at first, "this is a work-in-progress development project". there is no "best" "stable" "complete" "final" ver. for any purpose. probably I can't make such ver. in future. if you find something doesn't work, then you can't use it by any means.

I put all files for free (or under original free license). anyone can use/modify/redistribute/discuss it freely without my permission. but please understand, you(everyone) have responsible what you do.

I'll answer questions here as many as possible because I asked for testing. I will not be able to offer solution for your problem. sometimes I'll say "do not use" (just asking, not forcing), sorry.

thank you for your cooperation.
[Miscellaneous Android Development] fun_:
this is CyanogenMod. gapps is available(linked) on cyanogen.com and can be installed at any time from clockworkmod. about video, there is no hw video decoding on my CM7. you got only audio if you saw HQ video on youtube. see my OP/FAQ.

on stock ROM, I know video output is only on HDMI when HDMI is enabled. it seems tcc partition has some info, but I don't know/investigate detail.

at this time I have no idea for USB host on Scroll, sorry.
[Miscellaneous Android Development] hexx69420:
GB ROM CM7 MID7015A

dont know how it started or why but it now reboots to cm7 bootscreen when i put it in sleep mode when it comes back wifi is turned off any idea?
[Miscellaneous Android Development] Squel:
In my case this don't work. T73 have a capacitive.

I try again to load the firmware and do a calibration, maybe this will help
[Miscellaneous Android Development] fun_:
yup I know it's capacitive but you said it's inverted so "please try" :)
[Miscellaneous Android Development] Squel:
Calibrate it not working for me. Invert, hmmm..... when I click on down of screen, the top of screen is touching. On screen calibrating working all area of screen

Ok wait. two restart and screen working...... yupi :) thx fun_
[Miscellaneous Android Development] fun_:
sounds good :)
[Miscellaneous Android Development] phiit:
The calibration really got to me too, I had accidentally missed the first calibration point and it was all a mess :D. Flashed again and all fine, didn't have to reboot or anything. Good work!

Any hopes for HW video acceleration working soon?
[Miscellaneous Android Development] Squel:
Only two things don't work.

I can't enter to CWR, and wi-fi don't wont to connect to network
[Miscellaneous Android Development] phiit:
wow.. no problems here on those?

using LY-F521
[Miscellaneous Android Development] fun_:
no, my calibration app is really bad. you need to reboot to use calibration data after calibration complete.

no calibration is needed on capacitive screen(except Dropad D10) so you can cancel calibration app. if you finished calibration correctly, it should work too.

EDIT:

at this time no idea for HW video
[Miscellaneous Android Development] fun_:
for wifi, you need to do "wipe data/factory reset" from clockworkmod... umm...

please try following commands on root shell to factory reset

rm -rf /data
rm -rf /cache
reboot

EDIT:

or try "format" with FWDN. (in dropdown box above start button)

EDIT2:

what happen if you select reboot recovery in power dialog or run adb reboot recovery?
[Miscellaneous Android Development] will8578:
Fun, hope you are well, on the scrolls, would it be possible to merge the cherrypad rom with the scroll rom, so we get the sensors fixed by the cherrypad rom, and keep the speed of the scroll rom, if thats a stupid question, then forgive me..
[Miscellaneous Android Development] fun_:
only kernel, sensors.so, and ar6000.ko are different between scroll and cherrypad. probably we already tried some combination,

scroll kernel + scroll sensors -> no

scroll kernel + cherry sensors -> no

cherry kernel + cherry sensors -> yes but laggy

we didn't investigate this issue well. it needs more time.

my time is consumed by making 21 sets of CM7, updating sites, answering questions, eating sweets, watching TV, doing my job seriously, and so on ;)
[Miscellaneous Android Development] Squel:
If i select reboot to recovery the tablet restart, and i see a black screen

i try with shell

fastboot don't work for my mayby i try to flash witch CWR manager and in first flash thene change the recovery.img to yours and flash again witch CWR manager.

Ok. wi-fi works, i do this

rm -rf /data
rm -rf /cache
reboot

whether this img to FWDN recovery CWR is included

Is there any other way to install google apps ?
[Miscellaneous Android Development] fun_:
sorry, I couldn't understand what you did.

all you need is

a. flash D10-8K FWDN image then try reboot recovery

or

b. flash recovery.img in D10-8K recovery.zip with flash_image command on root shell, then reboot recovery

please do not flash other files.
[Miscellaneous Android Development] Squel:
Whene I choose a recovery reboot, the tablet off and that's all. Nothing else happens.

I try flash witch flash_image.

Sorry for my bad english
[Miscellaneous Android Development] will8578:
Drinking beer? lol take your time no rush mate, thanks. as i said on scroll, i installed linux on my laptop, downloaded the kernel because i wanted to see if i could overclock it, i seen all the files and stuff and hadnt a clue where to begin, so it makes me realise what an amazing job you are doing :D
[Miscellaneous Android Development] fun_:
no, I didn't do anything about kernel. I just use stock kernel from official rom.

there is no source for telechips tablets. it's mostly impossible to make working kernel without it.

Fun, i might hav found something whether it any good or not, on the cherrypad there is a file in /sys/class/sensor, it gives permission then >gsensor, now on the scroll it just says sensor, and then in /sys/devices/virtual in the cherrypad there is gsensor, but in the scroll is sensor, in the cherrypad also got a g_sensor_bma020 file but i cant find the folder the same in the scroll one yet, not saying its not there, just cant rem where it was.

[Miscellaneous Android Development] fun_:
I want to see /proc/mtd

and please dump & send me recovery partition after clockworkmod recovery.img flashed.

to install gapps, push & chmod 644 all files in gapps.zip then reboot.
[Miscellaneous Android Development] fun_:
sorry, I don't know how and why.

what did you do to fix this issue? already try "wipe data/factory reset"?
[Miscellaneous Android Development] fun_:
I think sensor device node is /dev/sensor and can be open() by someone's logcat...

anyway, for the record, please tell me "find /sys" comand result both Scroll and Cherry.

I'll make debug program to investigate this issue.
[Miscellaneous Android Development] fun_:
it seems you could post this message here... so what do you want to ask here?
[Miscellaneous Android Development] hexx69420:
i fixed it by installing soft locker i tryed wipe and i tryed blank recovery
[Miscellaneous Android Development] hexx69420:
not fixed just does it less
[Miscellaneous Android Development] fun_:
I don't know about "soft locker", but anyway, you tried wipe and not fixed?

maybe hardware issue? my Kyros 7015 GB ROM has no issue at this time.
