[Q] Coby Kyros Mid1125-4G stock ROM - Android Q&A, Help & Troubleshooting

Hello. I've been looking everywhere and I could not find a STOCK ROM for my Coby Kyros MID1125-4G. It happens that I installed ICS from Coby germany, but that slowed the tablet and has many problems with the WIFI, then updated via OTA to JellyBean and the thing was worse. Now I want to return to Gingerbread, but I don't have the stock image. Any of you have a STOCK ROM for this device? I will be very grateful for your help.

I think I've done pretty much the same as you....my tablet doesn't seem too bad...a bit glitchy maybe but I have no access to the APN settings meaning I can't use 3g. I'm hunting for answers as well.....if you find out anything before me let me know (and vice versa) :fingers-crossed:

---

I am glad im not the only one been trying to work out how to get the 4g sim card bit working again for the past few months since I did the update to ICS, was hoping the the update to Jellybean would fix it, tho I have a thought about the update if it helps that is when it downloads the update from the coby site it is downloading for the standard 1125 and not the 1125-4g model.
If i find out a solution or any more will let you know.

After hours of seraching on the net I now have my kyros 1125-3g back to 2.3.3 and with 3g support
I have uploaded the files needed to hxxp://kaosmad.com/android/mid1125/1125-3g.zip
There is a pdf file with instructions in the zip file but basically this is what you need to do,
0 make sure coby is turned off
1 - unzip the file
2 - install the drivers from the drivers folder (depending on your operating system)
3 - start the program FWDN_V7_v2.13
4 - click on the '...' button
5 - click on files types and change it to all files
6 - select lk.rom and MTD.img and click on open
7 - click on add files
8 - turn on coby by pushing the on button whilst holding the volume up button for at least 8 seconds, till the coby screen says plug in usb cable
9 - plub in usb cable
10 - wait for windows to finish detecting / installing drivers
11 - the FWDN software should now see the coby and show the memory allocation layout on the right side of the software.
12 - click on NAND Data from the block on the right and create file NAND Data.fai
13 - click on start
14 - wait while coby is updated
15 - when the screen says download complete (turns green) disconnect the usb cable
16 - reset the coby using the reset whole on the side with a paperclip or something else that fits in the whole.
17 - Coby should now be back to factory rom
Hope this is of some help

Thx for all the great info so far. It allowed me to make my bricked
tablet work again however it seems that I also have problem of the
"Damaged Nand". this message is preventing me from installing CWM after the recovery and
also upgrading to the latest ICS update provided by Coby.
Do you have any idea how to fix this ?? :crying:

From what I have read at various places you need to reformat the NAND (internal sd storage) and scan it for errors, this is a know fault as nands like hard drives can have bad sectors, which they write out when originally getting them ready for sale.
Most people recommend hxxp://panasonic.jp/support/global/cs/sd/download/index.html SD Formatter v3 to format it, obviously the coby has to be plugged into your computer to format it.
One note if you have the 3g version of the 1125 with the sim card slot using the coby germany upgrade to ics (or now updated to jellybean) using the updater on their site you wont be able to use the internal 3g sim card slot, this is a known problem to them and they are working on it.
If you need any more help just ask

Hmm I have dowloaded the SD Formatter 3.1 but it only formates the NAND memory ( flash erase is not suported ) i dont know how to scan for errors, also in FWDN it shows me that the NAND data is:
NAND DATA
( 3235840KB )
Is this ok ?
Also I want to let you know that the original coby germany upgrade to ics I can use the internal 3g sim card slot
I have now the update to ICS but now I dont know how to root and put the market on it, to bad

Did you guys have any luck trying to get APN settings working on your tablet, i mean with the 4.1.1. on?

---

sorry for my bad english
Is these instructions and the ROM for the 1125 without 3g usable?
If not, is there a tutorial for it and a stock ROM?
To explain:
I must have deleted important files in memory and can't run it any longer. it can not be started.
It is rooted. I would now like to re-flash.
How to get the 1125 in the CWM?

---

Yes, you can use it. I have also used it to come back to GB.

Hi ! I also have the same problem on my MID1125 (without 3G)
...> Damaged NAND.
I forgot to make Step 12 :
12 - click on NAND Data from the block on the right and create file NAND Data.fai
As i read on the internet, the Data.fai File contains the Parition Layout for the NAND Flash. Can someone can make a Data.fai File from his MID1125 Tablet ?
If you do the downgrade steps until step 12, the tablet will not be flashed !
Thank you...

After following the instructions I had an error and it would not boot.. so I did the same again but changed from "default download" to "Low format whole memory before download" (this does remove all your data as the warning states) then followed steps 3 to 13 again you need to do the NAND data.fai again so that it works and I have the stock ROM just added
Pplaystore via sd card.

Select language from first screen ( as it will be in Dutch ), finish setup of tablet
Open ES File Explorer , go to tools setting in ES File Explorer and select
“Root Explorer” to on , allow when Super User prompt shows , this will prove SU is installed and working
Open ES File Explorer , Select sdcard top right , Select storage
Install Google_Play_serv.ices-signe.d .apk ( To sync Play Store )
Install Busybox.apk
Install Link2sd.apk
Install Uni-init+v1.0.apk
Open Uni-init+v1.0.apk , install intd support
( you will need busybox installed first for this to work )
You now have working Play Store , Superuser and Android 4.1 with Intd support
For Extended memory ,( You need this )
Increase Internal Memory by Link2SD : Min 2 GB microSD
In order to add memory to Coby 1125, your micro SD card used for install will need to be formatted
Copy all files you wish to keep from micro SD to desktop as it will be wiped
• Backup all your files on memory card.
• Go into the Recovery Mode ( as above , fastboot boot recovery.img ) ( Your operating system will be fine )
• Make a nandroid backup at this time
• Select “Advanced”, and then choose “Partition SD Card”.
• Then Choose your size ( if you have a 2GB Memory Card, choose 512 MB, and if you have a 4 GB Memory card, you can choose 1024 MB, ext ).
• Select 0 Swap.
• Wait for the process to finish, and then select Reboot
You’ve just made a partition on your memory card, and its ready to use.
Now follow the steps below for Link2SD
• Open Link2SD. You will be prompted to choose between ext2,ext3,ext4 and FAT32.
• Choose ext2
• Select OK ,
• It will then say, “Mount Script Created”.
• Now you Reboot your Tablet
• Open Link2SD again, if any message does not appear ,it means you succeeded.
• Go to Link2SD > Setting( far right top icon ) scroll down > Check the autolink. (to automatically move apps upon installation).
If you already have some apps listed , select “create link” ( be sure to check the files: app, dalvic-cache, and library files).
Move to SD option only moves app to SD it does not link them
Now to check the memory, select “Storage Info” . this will be showing you up the current status of your internal memory.
You should see as below SD Card 2nd Part
To move a system App you can long press App , it will pull up menu , select convert to user App let it do its thing
Select App again and it will open option to create link as installed user apps do
So far I have moved Calculator , VPN , Music FX , ES File Explorer and Sound Recorder with no issue
Use Link2Sd and (long press) on SystemUpdate.apk ( /system/app/SystemUpdate.apk ) and freeze app.
This will stop System Update from happening at random moments or on reboot
There is no Update to install though the System thinks so (without freezing it will continue to show updates available)
