Greetings,
I have a Coby Kyros mid7125 that was given to me and I'm trying to restore/refurbish/upgrade it. It has some REAL problems, not the least of which is no functional OS. I have tried to install several different OS's including: ICS and JB. I am able to get them installed, and booted up. But, no matter which I use, the touchscreen is inevitably non-functional, and USB debugging is not enabled. Therefore, I am unable to do much else with it from that point.
I would like to install Gingerbread 2 . 3 . 3 which it had originally, but am unable to find a copy for this model anywhere.
I have searched MANY places online, including this forum (which has helped me Immensely! Thanks for that) but I'm just not finding what I need. Unfortunately, being as this model is so old, most of the links to what I need are no longer functional.
The tablet IS rooted, and I do have CWM installed, however the stock backup is gone, and there are no other functional backups on it.
Do you have any advice for getting the touch screen to work once it is booted into an OS, or where I could get a Custom or Stock ROM for this model??
I am fairly new to the Android universe, but do have quite a bit of experience with other OS's.
ANY help or links you could provide would be MUCH appreciated!!
Ok,....next problem:
Ok, SO........after MUCH searching, and hair pulling from my scalp,...and after not finding any answers here,....I decided to take a different approach:
I downloaded and flashed the firmware for the Coby mid8125 onto my Coby 7125 and it works just fine. Only one problem....the screen is out of alignment, which tends to create problems using the touch screen. Not a surprise considering the 8125 is an 8'' display while the 7125 is a 7'' display.
Back story: I lost the stock recovery image on the 7125 due to some "experimentation" with trying to upgrade the OS and CyanogenMod, and could not revive my 7125. Could not find any copies of the 7125 firmware or stock image anywhere. So, being as they are closely related, I flashed the 7022 firmware onto it. Worked,.....except the touch screen didn't function at all. Turns out, the touch screen on the 7022 has a Capacitive input while the 7125 has a Resistive input. So, I flashed the 8125 firmware, which also uses a Resistive input, onto the 7125 and regained functionality! (yay!!) Unfortunately, the display itself is offset by about 1/4 in. x/y, and receives the input at different positions depending on which side of the screen you're trying to use. (drag!!)
Now: At present, everything is functional, but it's a real hassle constantly turning the tablet, and tapping in different places to run the thing.
So, my plan (another experiment) is to copy the TS driver from the 8125 firmware and insert it into the 7022 firmware (which also uses a 7'' display) and hope it works.
Problem: I need to know where in the file system, on the 8125 and the 7022, to locate the driver for the touch screen???
If someone could provide me with the file path, I would be grateful, and would definitely post the findings of my "experiment" here for others to reference. I know others have had the problem of losing functionality with the touch screen, and this could turn out to be workaround, if successful.
I would like to thank the Many others here whose posts and links have, indirectly, help me in my first foray into the Android universe. Without your sharing I, for one, would have been completely lost with nothing to show, except a nice paperweight, for my trouble. So,.....Thank You ALL!!!
FIXED IT,......Mostly!!
So, it appears tenacity pays off!
Through my own persistence,research, and experimentation, (and with no help from the various forums I've visited)... I managed to come up with a clean, Stock ROM and Backup of Coby MID7125 and, using CM v6, I have flashed it onto my 7125 and have restored it to full functionality! Everything works. Only one problem remains......
The display is still out of alignment. I have tried various means of realigning it, from re-calibrating it to trying to access the POINTERCAL file to adjust it manually (which I'm still trying to access), all to no avail.
I realize this is an Old tablet, and mostly no supported by, well, anything. I am using this as an exercise in familiarizing myself with the Android system before moving on to a more Updated version and device.
I've had some failures and some victories, but I am learning a lot and making progress in leaps and bounds. Although, it seems as though I'm doing it ALL ALONE!! I get no help or even suggestions from anyone on any of the various forums I've visited, and the research is mind-numbingly tedious at best.
Still,.....this problem with the (resistive) touchscreen alignment is my last hurdle with this restoration project, and I could REALLY use some input from someone who is better acquainted with these systems.
Anyone?? Anyone at all???

A relative of mine has a cheap tablet and it's pretty beaten up. However, he wants to give it to his niece and isn't of a mind to buy a better one. He got it second hand, and the thing turns on, and goes to an "android" screen. There, it does nothing. It freezes and stays that way until it dies. I was wondering what the best way to go about trying to fix this thing. Would identifying it be the first thing and if so, could anyone offer some guidance? I'm no stranger to rooting and flashing custom roms and the like, just not sure where I'd start. Any help would be greatly appreciated.
Bump
ninjames, have you checked if this device has a recovery installed. If you are lucky and find the correct buttons to boot to recovery maybe resetting to factory defauls will bring it back to life.
Can post a link to a picture of your device (front and back). Maybe someone will recognize it and will point you to a stock rom which you can reflash.
- Identify the device (OEM, model etc.)
- If it's a "known" OEM, it probably has its own forum section here, so check that out for more help if that's the case.
- Try to google "device name + model + bootloader buttons", and if you're lucky, the bootloader will have its own stock recovery (like Samsungs, LGs etc.)
Hi Guys, first of all thank you in advance for any answer you could give! it will be much appreciated!
Now, before anything I know there should be hundreds of posts about this issue but I was unable to find one that could apply to my scenario. But if you know any post that could be what I'm searching please just point me in the right direction :good:
Now, here is the problem:
We bought this cheap chinese tablet with andrioid 4.2.2 for my mother and it seemed to work pretty slow and some apps where not working correctly, there where a lot of adds even when she was not on an application, they just popped out on the main menu screen, and, when trying to register Instagram it displayed a message stating that there where too many users registered in the device. I tried to root the tablet because found that it could be because some temp files but it showed that it was already rooted... So my guess is that whoever installed the OS, did it with a "hacked" version of it.
Up to this point I have tried to do a hard reset but the issue is still going because it is still the hacked version of the OS, and I havent been able to find a way to completely wipe out the OS and install a fresh new version of Jelly bean 4.2.2
Can it be done with the device conected to a PC? or can it be done with a flashed memory card?
I know finding the firmware for a chinese tablet will be a major pain in the ass but, is there a version that could work for different models? (this is a Mobix MBX7 Plus, found the website mobix.com.ve but there is just no helpful info whatsoever)
Anyway, I hope you guys can help. Sorry for the somewhat long post
Again, thank you!!
Update!!!
I found info that could lead to the correct firmware, the CPU is an Allwinner Cortex A20, but Im still not sure if this format process is just like a PC, where you need drivers or everything is on the OS
Hiya
I have an Alcatel Onetouch Pop C1 4015D (and for the record, I'm never buying this brand or similar junk again). I just got it un-bricked after a few months thanks to the online USB firmware updater. It's currently in pretty much its factory-default state again, preinstalled crapware and all.
What I'd like to do is install a custom ROM on it, to have a clean system I can actually enjoy owning, e.g. AOSP (if that is what I think it is: the basic, clean Android system). The problem is that I'm getting a little overwhelmed with information, tutorials linking to more tutorials, tutorials linking to downloads for which I have to "complete a survey" and such (abort abort abort), 2 different tutorials for the same thing stating different ADB commands, a few outright scams, etc etc etc. There's tons of information out there, but 90% of it seems wrong, irrelevant, device-specific or otherwise unusable. I've already spent hours on this and still haven't gotten anywhere.
I'd be very grateful if someone actually reliable could walk me through the entire, correct process, please. :fingers-crossed:
I'm just going to write down the bits and pieces of info I already have:
I've already rooted it with Framaroot; no problems there, superuser works.
I've found this site that lists several ROMs, presumably specifically for the C1, including the standard ROM and a cleaned version: tinyurl dot com/o24wqoe. The AOSP one strikes my fancy and is on my SD card already.
The same site says I can just put the provided ROMs on my SD and install them as updates via stock recovery, but I highly doubt that because I read everywhere you specifically can't do that. Sounds like fake advice to me.
I'm told I'd need to unlock my bootloader, but once in fastboot/bootloader mode none of the offered fastboot unlock commands really do anything. The "..." appears in my console and then nothing.
I've tried installing TWRP and CWM recoveries, but you know, "your device is not supported". There's this video of a C1 with a custom recovery (watch?v=_TGgXIp3fWM) and the comments claim it's CTRecovery, but I can't even find anything about that. I already submitted requests for a fix for my device to twrp and cwm half a year ago before I bricked this thing, and one person promised he was gonna make a build for me, but nothing came from any of that.
I think that's just about all the useful things I can extract from this whole mess of information I have...
Please help me make sense of this overload of info and device-specific shenanigans, and walk me through what seems to be such a simple process for everyone with a mainstream device?
For the record, I'm back down to barely being up-to-date on what is what anymore. I'm more than familiar enough with the theoretical side (bootloaders, partitions, bios, etc) because of my heavy computer usage (professional programmer), but once I get into Android I'm just lost. All that fancy terminology nobody seems to bother to explain, things that are taken for granted but aren't really obvious (like a guy demonstrating the installation of a custom ROM, and only mentioning 10 minutes into the excessively long video that you need to install a custom this and custom that first), so many alternative methods for the same thing that have different dependencies (unlocking bootloader vs custom recovery), etc... I don't know anymore what's device-specific and what isn't, who is telling the truth, what a given tutorial is actually making me achieve in the end, etc. TL;DR I'm lost, I'm not stupid but I'm not gonna pretend to know anything about Android's subsystems anymore at this point.
wow u wrote a full post and u speaked for me as have the same problem
Custom recover
i have made a recovery for the 4015x
and got one of the roms to work
(and a fixed stock recovery)
there are 6 versions of this phone and at least two different partition tables that ive seen
but getting it back from softbrick id use the "mobile upgrade s 4.1.1" from the alcatel site
alcatel,mobiles,all mobiles, pop c1, support and on the right hand side down load the program and follow
this forces a stock rom back on the phone (no root and all data wiped)
im waighting on the mods to let me post links so i can host the roms and recoverys
but if you want to mess with the roms your self you can edit the partition tables and get the roms to install.
id use the app "diskinfo" to check what partitions your system and data etc etc are useing and chainge this in the roms.
hope this helped
p.s. if not i could poss look at editing the aosp rom for you and host if for a bit
just waighting on beeing able to post links :s
Alcatel onetouch c1 pop
MY PHONES flash light or led light comes on but it wont come on at all jus remains black wont start ....i tried restoring rom but ,it was useless ,well i used the upgrade tool and there wasnt the right models for my phone what should i do now .oh and also my phone has no stock rom from nowhere on google im so in need of getting back my phone .how can i fix a bricked or whatever phone its a alcatel one touch pop c1 4015a
What is the online USB firmware updater? Mine is also bricked
Hello i have a 16GB chinese tablet that stopped working (boot loop, nothing i tried would help) and have been hunting around everywhere for a compatible firmware to flash. Perhaps in haste, after reading that the Versus TouchTab 10 may be the same product, i tried flashing a full .img ROM that was on softpedia for the Versus but it has not helped. If anything it's only made things worse as now as the red light doesn't turn on at all with the power button. I have also tried a couple of other ROM's for similar tablets with similar specifications but no joy. The tablet does boot into LOADER mode though and i can flash the device without any problems, so it's not completely dead.
Might anyone have a copy of the firmware for this tablet stashed away somewhere? I'd really appreciate it if they might be able to upload it somewhere if they do.
The tablet has no branding but the parameter file i extracted before jumping in an flashing it said CnM-TP-10DC-16-B for the model. So it would seem this is a CnM TouchPad 10 DC 16GB. Hope this is helpful.
Many thanks,
James.
What board version is it? I have a couple of dumped ROMs for this tablet that I might be able to help you with.
hey guys,
i'm having hard time to find out how exactly to flash my old oem tablet and i really dont expect anyone here to search anything about it(i do that...), just to guide me in general please.
i just found this old tablet and thought i could try to use it as a touchscreen-mp3 player connected to my amplifier...
i charged it and powered it but stuck on "android" logo, i tried many key combinations to put it to recovery mode but i just couldnt find it i guess.
then i started searching of how to flash it...
what is visible from outside is "f&u ETB7405" which brings almost nothing(it's just an oem model) so i opened to see inside where i can see one chip "allwinner a13" and "tzx-q8 713B 6".
it has 7" screen.
based on these i finally found a fimware (using PhoenixCard) that boots normally BUT i get no touchscreen or wifi working. i can connect a usb mouse and have access to it.
do i also have to flash any extra firmware/driver for just the touchscreen or wifi?
what is the most important characteristic("A13" or "TZX-Q8...") to concentrate my search for?
why is it so fcn difficult to find a working firmware???
in case anyone else is having the same issues and hopelessly tries to find the firmware for his device and bumps in unanswered posts or dead links, guys just try different "A13" firmware! Although i'm not really sure that it even has to be "A13"!
i was trying to find firmware with the most of my specs on its name like f.e. "A13-TZX-Q8-713B6" but the paradox happened. the most similar firmware names were not good and i tried a lot! instead i finally decided to just search for "A13" firmware and try any of them one by one despite the names. that was it! i have already found a couple!
from here: ww.androidtablets.net/threads/firmware-based-on-allwinner-a13-roms.72449
a13-TJ P860-V7.1-gsl1680-MID-756-V4.2-20130823-test-keys.zip
all works but there is only "english" and "thai" in keyboard languages.
A13_TWD_MID-gslX680-800X480_20130423 test-keys.rar
all works but touch screen "mirrored" sideways!
good luck to you guys!
thanks
