Hi guys! I need some help.
I bought some cheap tablet from auction, where storage showed 2 internal memories. One of them were 0.00b and other were 4.9 something gigs.
I tried to load one custom ROM on it with AML flash ImageBurnTool, but this did'nt end well. Now I'm stuck in Android system recovery 3e screen and only possible way to load something is adb sideload or read from SD-card.
Edit: Probably this tablet is hard bricked and I need to find out what pins need to shortened to load fresh rom into it. Chip is H27UCG8T2ATR
Edit2: I found that it is possible to short chip pins to view device. pins 8 and 9 from top left. Search instruction from google: Unbrick or fix NAND on the MK808
Now the only problem is that how to find proper ROM for installation.
Firstly: is there any possible way to find factory ROM for this tablet? Previous ROM were custom already so backup were unnecessary.
Secondly: is possible to do something else with this tablet than using as cutting board in kitchen? As loading some other OS in it or booting from memory card or anything else?
Regards fellows!
I need this rom too, anyone? Or another rom that works on this device?
Maybe I refresh this question. I'm one of many people who are looking for this stock rom or another what is running well on this tablet. I post a message to Salora service in NL to send a file with stock rom for this tablet but they told me that there is no posibility to send this file because they don't have nothing like that. So I have a question. How they repair bicked tablet where ROM fails??? Sorry for my English
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
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???
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.
Hello all,
Recently my Lenovo stopped booting and it gets stuck in a bootloop. I still have access to the reset mode by holding volume up and down.
I have the 4GB RAM version. Is that enough information to fix the issue? Let me know if I need to supply more information (and how to obtain it, please).
I tried looking around for solutions. Many people seem to have fixed similar problems. Unfortunately their posts usually contain dead links so I couldn't use their methods.
If I need to reinstall I would prefer an English system. There is no important data on the phone. It would be nice to be able to retrieve contacts but it's not a big deal to lose them.
Thank you in advance.
Hi. Unfortunately you canot recover the information after the phone entered in that state, unless you are doing backup in clowd.
All you can do is to reflash the firmware with SP Flash Tool.
Here is the link for multilanguage firmware: https://forum.xda-developers.com/lenovo-p780/development/firmware-row-cn-layout-t3550801
Here is one firmware that i like: https://forum.xda-developers.com/lenovo-p780/development/miui-lenovo-p780-t2976347
Read the tutorials twice before you do anything.
Tell me if something goes wrong.
Good Luck.
