With thanks to miguel, i managd to recover the corrupted internal SD but the touch scren is still not touch sensitive.

Any ideas anybody please? am worried now as i bet my warranty is void as i opned the unit to access the internal sd

Maybe the little yellow cable got disconected while sliding the back cover

interestingly, just tried to download some apps and it says my device is incompatible with fruit ninja, toddler lock and angry birds... is this linked??

[miguel.arce]

Strange ... maybe you should contact merimobiles about the faulty screen
As long as you didnt broke anyting you could ask for a replacement unit

Its a known issuue of firmware 929 check the kill internal phone app thread and the t9 faq thread for fixes

which parts a known issue sorry?

The market saying it is incompatible

Hello all. Based on what I can find on the internet, I have a T9. This is a tablet from a batch of different tablets that my company bought to explore the idea of selling / donating them for different uses.
I am tasked with modifying the firmware for some custom options for our company.
In playing around with the different version firmware, mine apparently is running a newer version of the other ones linked on the 'pinned' pages. I tried the next back firmware and lost the touch response. I've reverted back to the newer firmware, thanks to a backup I made of the system and data partitions, but even returning to the newer firmware, I still do not have any touch response.
I can only navigate using a mouse plugged in.
I've verified the little yellow cable is plugged in, even un-plugging it and re-plugging it.
Does anyone have any ideas on this before I have to take it back to the office and file an issue with my device ?
BTW, the firmware I installed was the 20110929-T9-StockFirmwareUpdate-Gingerbread, the device apparently already had a 201110** firmware on it, that I actually was dyslexic and that it was older than the 201109** firmware.
If anyone has any ideas etc, I'd appreciate hearing them.
Thanks

hi,

if T9 wont respond to touch it must be a hw issue ( there are two "yellow flat wires" comming from the screen to the main board, make sure they
are firmly connected ( and securely taped to the board before sliding the cover ).

too bad you didn't create a full microsd image of that firmware, 929 is the lastes firmware that i know, i your T9 came with a newer one
i would love to have the chance to take a look at it.

best regards,
Miguel.

Miquel, thanks for the quick reply. After popping the casing off again, the smaller connector used for the touch screen appears to have a slight bump on the edge, perhaps caused by me, but if so was done only after the rollback to the 201109 version. I do know the case had been popped off a couple times by someone else to charge the battery. All three tablets we ordered came with the wrong power adaptor, so one of the guys at work popped the batteries out and charged them. Could be that he caused the slight bump in the edge of the connector and it finally isn't making contact now in that yellow ribbon.
I do have 2 more of these that all came at the same time at the office. I'm on vacation for the next week and a half, but I'll try to stop at the office next week and get a Linux DD image of one of the SD cards on one of the other 2 units. I know that no one besides me is doing firmware mods. Everyone else is just testing apps and battery lifetime etc.
If you have anything specific you would like me to do, specific method to back up the internal SD let me know and I'll do that. I'm going to get in touch with the guy keeping the tablets hopefully this weekend and trade mine in hopefully before Monday.
Again thank you for your quick reply, and let me know if there is anything specific you want me to do when I get one of the other tablets, they all have the newer firmware, and the other 2 won't have any changes made to them, except for maybe some software installed, that I'll do a restore before backup.

hi, do not do a "restore to factory", you will end up with a posibly unbooting device. i had a tweaked T9 with firmware 929, i moded the partition sizes
(data and cache) and when i did a restore, i loose all those tweaks.

for backup up the microsd image in linux dd is ok dd if=/dev/sdX of=/somedir/microsdbackup.img
better to be done in windows, as some linux distros tend to auto-mount partitions in removable media, and that will
modify the partitions info before you could do a backup. if you are in windows you can use winimage.

and last, the content of the microsd cards (the ones i have examined so far) is somewhat this:
there is some "unpartitioned space" in the beggining of it, (about 33-43 MB ), then the "first created partition" is
the a FAT32 that is used for user space for data, this is located lastly in the microsd but in the partition table is
the number 1.

the partition number 2 is located directly after the unpartitioned space and it is the system partition ext4, the content of
this is in the system.img file of a the firmware ( the firmware came with an update.zip and inside that zip there are
two files boot.img ( that contains what is in the unpartitioned space, and system.img )).

partition 3 and 4 are data and cache, they are both ext4, they are after the system partition, FAT partition (number 1) is after this two.
the content of this partitions are created by the tablet when it boot up and with usage, so they are really not important
you cand modify this partitions or create them from scratch, the only thing you must be carefull is to set the
partitions uuid's to the expected values and to set the last mount point value also, or the device won't find them
and won't boot because it needs some r/w space.

and thats pretty much what i have learned while experimenting with this device.

Miguel,
My primary workstation is Linux, I've disabled automount options, so doing a 'dd' will be fine in my case. I hope to have a reply from the person keeping the tablets tomorrow, as long as I can get access to one of them I will stop in and make a 'dd' image of the internal sdcard and toss it online and post the link.
Your examination of the partition sizes and functions are spot on.
After I get a image of the SDCard I'll toss another reply on here.
Best regards,
TSN

Miguel,

I sent you a PM on here with a link etc to the Firmware. Hit me back to let me know you've seen it etc.

I did the same mistake to install 0929 fw and now the touch is dead!
Anyone has the 20111025 firmware?

[miguel.arce]

hi i got an image from another user with the firmware you say

i havent got the time to test it but it should work ask user tsn about it or maybe later i could posr it online for you to download

best regards
