Fun_, tried to build CM7 after a few changes to the device- and vendor-files for the Yarvik Tab211. Building goes like a charm, but when I flash the newly build zip it stays at the first screen when you turn the device on (same screen I see when entering fastboot, so I guess itś in fastboot this time also, didn't check)

I had the same thing when I made changes to the zip you build and flashed that.

Any idea?
[Miscellaneous Android Development] fun_:
please tell me what you changed. you should try without change at first.

it seems there is no tux logo in tab211 kernel, so it's difficult to know kernel is running from screen. in addition to fastboot, you also can use adb to check tablet is detected or not.
[Miscellaneous Android Development] Arjen:
Just made some changes in build.prop (because of ril-files), added some ril-files to try to get umts working. (In your zip-file)

My own build I made some changes like changing rom to hdpi, solving sd mount-issues and adding things named above.

Also changed some things in unzip_files because of named changes.

Will try with clean build later.

I see you are using some other files like tcc_nand.so which isn't used in stock GB rom for Yarvik? Guess itś used in some other roms for Telechips based tablets?

Didn't have time to check things because I had to leave.

Next time I will also take a look at the logcat, but it I found it strange that after adding something to the zip it didn't boot anymore, even after adding another package or changing build.prop.
[Miscellaneous Android Development] Arjen:
Several options:

Flash using fastboot or flash an update.zip for your hardware if itś provided by your manufacturer.

How to update with nightlies build

I have a roverpad(qware pro 2) tablet.

My tablet is working ok with cyanogen mod, the problem with the clockwork recovery, is gone.

Now i want to update my tablet, with a nightlies build, i can download it, and when i boot in to recovery, and install form sd card, i get an error(0).

What is going wrong, please help.
[Miscellaneous Android Development] Jasio_m:
Hi Fun_,

A while ago you mentioned that you could do a build for the LY-F521 1024x600 with the old kernel. This was because the new kernel stops the tablet from sleeping.

Would you have time to do it? I would appreciate it very much. With the current builds I have to keep it on charge pretty much all the time. And the old version I have been using has become almost unusable with the new market.

Cheers.
[Miscellaneous Android Development] imnotamorningguy:
Nice work on CM7, looks sweet. When i flashed it i lost android market and wasnt able to install it the same way as before. Anyone experience this issue? Solutions?
[Miscellaneous Android Development] Arjen:
What nightlies build you downloaded? If it isn't a build for your device you won succeed. Need to build your own nightlies build otherwise.
[Miscellaneous Android Development] fun_:
other tablets also have "ramdon wakeup" issue. I want to use my time to investigate it but anyway currently no enough time for anything.

really sorry.

if you have time, you can build own CM from source.

thank you for your cooperation.
[Miscellaneous Android Development] fun_:
on stock rom, tcc_nand.ko is in ramdisk in boot.img.

on my CM7 for TCC8902 GB ROMs, most proprietary files are taken from EM71(GPAD701) ROM. I'm trying to share files as much as possible. sometimes it makes problem but it should work for Yarvik TAB211 because non-modified my build image is running on some Yarvik TAB211.

my files for Yarvik TAB211 e.g. kernel are taken from dumped image by some person. I'm not sure it's latest, and not sure it's same as your stock. if you have info about downloadable official rom or latest one, please tell me.

fun_

When I use unzip-files.sh to extract kernel, the pagesize is set to 33170, but when I look into boot.img-pagesize it is 8192.

The file mkbootimg work fine when I set BOARD_KERNEL_PAGESIZE := 8192 on BoardConfig.pagesize.mk, but when I change it to 33170 I got an error on mkbootimg.

There is any problem to use pagesize as 8192 instead of 33170?

Thx for your attention

Afonso Lage.
[Miscellaneous Android Development] fun_:
oops. old unpackbootimg generated boot.img-pagesize like "00002000". it was hex value without "0x" prefix.

now I tried latest(with change at Sep 4) unpackbootimg, it generates "8192". oops. 0x8192 == 33170 is wrong of course :(

please modify BoardConfig.pagesize.mk to use 8192 for your case. otherwise generated boot.img is unbootable :(

--

_Arjen_, please check your BoardConfig.pagesize.mk.
[Miscellaneous Android Development] vampirefo:
fun,

Do you have any plans to add ext4 support?
[Miscellaneous Android Development] akshaydusane:
thanks for solution

i recovered it successfully....

now i am having cm7.1

bt not able to launch android market app

any solution for dat ??
[Miscellaneous Android Development] Arjen:
Ok, will take a look at it.

By the way, Sweex told me they will release source code shortly,

they will notify me when it's released.
[Miscellaneous Android Development] afonsolage:
I'm glad to help you to improve this ROM ;)

I changed the unzip-files.sh removing the "0x" from:

to:

and it gerenated the BoardConfig.pagesize.mk correct with 8192.

Thx for your help.

Afonso Lage.
[Miscellaneous Android Development] Arjen:
Will do that ;)

Edit:

Just checked, already had it that way...

BOARD_KERNEL_PAGESIZE := 8192

BOARD_NAND_PAGE_SIZE := 8192 -s 256

---------- Post added at 08:35 PM ---------- Previous post was at 08:25 PM ----------

For that a modified kernel is needed, dont know if fun_ has time for it, but I have plans to build a modified kernel after completing some other things.
[Miscellaneous Android Development] vampirefo:
I already have the kernel for it. Just need recovery to mount and format as ext4.
[Miscellaneous Android Development] Arjen:
In that case you need to add that kernel to your recovery.img

Perhaps also need to change something else, didn't look at it yet.
[Miscellaneous Android Development] akshaydusane:
hello guys i have jst uploaded cm7 on my telechip tab.....

bt i am not getting access to market any1 having this problem solved please tell me??

Is it a bug in cm7??
[Miscellaneous Android Development] vampirefo:
I don't have any problems with Market nor do I see how a recovery could effect the market. You could always flash back to stock recovery and see if your problem is fixed,
[Miscellaneous Android Development] afonsolage:
You can say at least what type of error you got?

Your maket won't open, you can't find maket or you can't install any APP on market?
[Miscellaneous Android Development] akshaydusane:
It opens up for 1 sec den it terminates quickly......
[Miscellaneous Android Development] afonsolage:
Can you show us the LOGCAT when the problem occurs?

Open LOGCAT (via ADB LOGCAT on a PC with you device connected through USB);

Open Market;

Save LOGCAT log and send to us.
[Miscellaneous Android Development] Arjen:
Did you install it directly or did you do the 'wipe' before flashing?

What are the commands to build from source?
[Miscellaneous Android Development] dr_997:
Hello

you should add the steps for installing google apps "market and other apps"

www wiki.cyanogenmod com/index php?title=Latest_Version#Google_Apps

you can installing CyanogenMod 7 Google Apps.zip by ClockworkMod

these apps cannot come pre-installed with CyanogenMod and must be installed

and thank you this post hepled me to unbrick my mid7016
[Miscellaneous Android Development] Arjen:
Please do a little research...

You can take a look in the CyanogenMod wiki for example...
[Miscellaneous Android Development] vampirefo:
I already have searched no info on wiki thats why I asked. What would help would be the commands used.

Anyway if someone wants a small donation and has either a paypal account or is selling android apps on market. Send me a how to on compiling this and I will make a small donation or buy one of your apps.
[Miscellaneous Android Development] Arjen:
You can take a look at this

You also need to download needed sources from github.com/naobsd

Do not use ./build.sh epic after . build/envsetup.sh, just type lunch and choose your build.

After that you enter make otapackage to build the zip. Personally I first do a make and after that the make otapackage

If you get stuck anywhere, please tell :D
[Miscellaneous Android Development] akshaydusane:
sry friend i didnt got u explain..

---------- Post added at 04:23 PM ---------- Previous post was at 04:22 PM ----------

i installed it directly....
[Miscellaneous Android Development] Arjen:
Try the following (like told in one of the first posts):

Boot into recovery, wipe data/cache (factory reset)

Install CM7

For market etc. you can install this using CWM.
[Miscellaneous Android Development] vampirefo:
I don't have time to try this, anyway i sent you a donation as promised, thanks for the help hope it works.

Best Regards

Vampirefo
[Miscellaneous Android Development] Arjen:
It is possible to pre-install some apps with CM7, but it's a choice that's made to not do it.

Next, we cannot use Rommanager yet, we need to add our tabs to it first.

We can ask Koush how to do it or do it for us.

---------- Post added at 04:49 PM ---------- Previous post was at 04:48 PM ----------

It should work.

Sometimes it's also advised to format /system before flashing (we do it on LG Optimus One for example)

And thanks for the donation ;) You didn't have to :D We are here to help one another.

You didn't find your answer after searching, so I shared the knowledge :p

Youtube playing HD

I have cyanogenmod working on my Qware Pro 2 tablet (same as Roverpad 71).

But the only thing what's not working is Playing HD video in Youtube, it's get an Black screen, en audio is play, bu no video.

How can i solve this problem, please help.
[Miscellaneous Android Development] nba1341:
make sure file is under tflash folder... or possibly the /sdcard/ folder. Depends if its supposed to be on nand or external sd card
[Miscellaneous Android Development] reaper420:
yup did that, i guess i'm stuck with factory recovery. no method ive tried has worked so far. i even unrooted and factory reset the tablet so i could have a fresh start, and still nothing. the zip always installs, but has no efect. i tried it through the system update menu also but it will never show that i have an update to install.

Hi Fun and the team,

Just wondering if there's anything new in the pipeline at all as I noticed on androtab.info you've managed to get accelerated video running on one device :-)
[Miscellaneous Android Development] fun_:
I'm under attack by some guy who is saying "I did it! fun_ just use my work!" ;)

anyway currently what I know is exact same way doesn't work on telechips. sorry.

EDIT:

btw new images are prepared. it supports NTFS with ufsd.ko from stock rom. but probably disk space of my web server is not enough, so I'll remove current image just before upload new image. sorry for this inconvenience.
[Miscellaneous Android Development] s'pht:
Going to try this here, fun_ and everyone else might actually know the answer:

I'm trying to modify some stuff in the boot.img file on my gentouch78 (v1) but for the life of me I can't get one that will actually boot and I think it's because the "--base" option that I'm using is wrong.

split_bootimg.pl give me:

Page size: 4096 (0x00001000)
Kernel size: 4137184 (0x003f20e0)
Ramdisk size: 824428 (0x000c946c)
Second size: 0 (0x00000000)
Board name:
Command line: console=-ttySAC0 androidboot.hardware=tcc92xx
Writing boot.img-kernel ... complete.
Writing boot.img-ramdisk.gz ... complete.

and based off some stuff I've found around the web I think I should be using the following to recreate the boot.img:

mkbootimg --kernel boot.img-kernel --ramdisk newramdisk.gz --cmdline "console=-ttySAC0 androidboot.hardware=tcc92xx" -o new_boot.img --base 0x40000000

Anyhow, the boot.img that creates won't actually boot the tablet - it never makes it to the tuz screen. I've also tried omitting the --base, 0x4DC00000, 0x49800000, and 0x40008000 (I got those from looking at the source for the kernel off the telechips site). I know it's not cyanogenmod 7 related but I'm just hoping someone will know... anything about this.

my one is aocos n19.

i cannot boot my tablet but can flash firmware from FWDN.

I think stock recovery is missing.

Any idea how to restore back the recovery image as FWDN didn't accept the recovery image and adb cannot detect it?

Many thanks.
[Miscellaneous Android Development] crazythunder:
i just bought a coby kyros 7127 for my daughter for christmas. i tried dump the stock recovery image. i did this by naming the dump-recovery-signed.zip to update.zip. then went to settings and updated from sdcard. all looked like it worked, but i had no dumped_recovery.img or dumped_proc_mtd.txt on root of SD card. is the 7127 too new for this process? i wanted to install cwm5, but it seems like there are issues yet, ie. hdmi out,mic not working etc. does anyone out here have this model yet? or does anyone know if i should simply wait for this model to be officially supported,because it's not listed on the devices list. i just thought because some kyros can flash the same files that this would work. or, i'm doing something wrong? thanks in advance.
[Miscellaneous Android Development] fun_:
there is no "official support" here. just waiting will not solve anything.

you should not use any files for other tablets. many people bricked their tablet by doing it.

sometimes dump-recovery.zip doesn't work. in this case it needs to be dumped manually from command line shell.

but, before doing anything, you need to get detail about your tablet. please try to get output of "dmesg" and "cat /proc/mtd" commands at 1st.
[Miscellaneous Android Development] fun_:
you should try non-modified images (just unpack/repack-ed one) at first. I have no idea about what's wrong, tool, procedure, or modified image.

wtf lol i was using droid explorer. i hit "reboot to recovery" and guess what it rebooted to? cwm5! lol. i attempted it before but i got no confirmation. i don't even know how to boot this thing in to recovery. holding vol.- and power takes me to fastboot. i'm gonna try vol.+ and see what happens. i read hdmi out is broke among other things. if it is, i have to find a way to get stock recovery back.i'd still like a copy of the stock recovery, but i don't see much info around about the 7127. is it that new? grrr. well, at least it's not bricked. anyone know how to boot this into recovery from the tablet itself? vol+ and - brings me to fastboot. only way i know of right now is with droid explorer from within windows.

great job! thanks for your work on a cm7 port for telechip tablets!

do you think there will be a cm9 port in the future, or are most of the tablets not powerful enough to fulfil the hardware requirements of Ice Cream Sandwich?
[Miscellaneous Android Development] Arjen:
CM9 is possible for most tablets, but due to lack of ICS libs for our tablets it's a little more work to get it running at this moment.

Currently I'm working on CM9/ICS for Lg Optimus One together with some others,

perhaps after that I can take a look at tcc8902-based tablets.

MID-7CD Help

Hello! I bought me 2 of these MID-7CD tablets from china. One was tweaked a little different than the other like CZ locale or UI.LCD.DPI set to 161... They both run 2.1 Eclair and have different build dates. one is October of 2010, the other is Febuary of 2011. Both have an internal 2GB nand. The first thing I did was create backups of boot,data,cache,system, and recovery using dd if=/dev/mtd/mtd0 of=/sdcard/boot.img bs=4096. /proc/mtd looks like the normal TCC8902 style. 0=boot, 2=system, 4=cache, 5=data, 6=recovery.

Next I tried installing CWMR5 from the EM71 list. It stuck at the android 2.1 logo, so I then used recovery.img from the EM51 model, worked. I am able to boot CWMR5 and scroll and execute. Buttons are different but manageable. No scroll up tho, only down... So I made another backup using CWMR5 on both tablets. I wanted to clone the model with the latest build to the other. So I loaded up CWMR5 and formatted Data, system, cache, and boot. Then performed a restore. All data wrote correctly. Now when I rebooted I get an error saying "Error: normal boot failed. Entering fastboot mode..." Immediatly.

I've tried restoring both copies of the clockwork backups. Both give the same issue. If I use "fastboot flash boot boot.img" the error goes away!, but it will not continue past the android 2.1 boot screen. The screen does blink once. The same as when it is about to enter clockwork. USB also connects, can't remember if adb works at this point. (I'm at work now)

At this point I'm not sure what to do and am looking for pointers. I have a manual backup and a clockwork backup for both tablets. There is no info for the MID-7CD model. Willing to try different img's as I have fastboot and CWMR5. I also tried "fastboot flash boot recovery.img" and my original default recovery image booted up with the Triangle Droid. So I'm confused as to where boot.img is broken or if system.img is corrupt. Let me know anyone needs files..... I'll put them up. Thank you!

[Miscellaneous Android Development] akuma6099:
Figured it out. The system.img created by dd if=/dev/mtd/mtd2 of=/sdcard/system.img bs=4096 will not work. You can't use fastboot on it. It gives an error. If you dd it back, the filesystem is garbled. I only figured this out because "adb shell" was giving me an error saying "exec - /system/bin/sh - no such file or directory" when system was corrupted. Tried multiple copies. Luckily I had a CW backup too. Used CWMR5 to restore system.yaffs2.img and data.yaffs2.img. Then rebooted to FB mode(VOL+ while powering on) did, fastboot erase boot, fastboot flash boot .\boot.img, fastboot reboot. All is well! Any other attempt at flashing the boot.img failed with "Error: normal boot failed..." message(flash_image boot boot.img and dd method).

On a more topic relevant note: I tried both the EM51 and EM71 CM7 mod. Used the "Update from ZIP file" option in recovery. EM51 ended up rebooting before the UI would pop up. Never finished out of 15 boot attempts. logcat was at a different spot every time. The EM71 image works and looks great. The digitizer needs some tweaking and so do buttons. Volumes work, home acts as menu, and back equals back. Seems a little slow. There's not alot of horsepower on this thing. Well hope this helps someone.
