[Q] How to resurrect tablet pc after wrong update.zip installed?

Hi, I have tablet pc with Telechip 8923. I tried to change resolution with LCD resolution app, and after reboot it doesn't start. Stuck on ANDROID booting last page. I didn't have firmware, and I tried to install update.zip from freelander tablet, and then after reboot it was worse. Only 1s shows android screen and goes black. I talked to manufacturers and they sent me my tablet update.zip but its doesn't helped. Nothing changed. first screen and after 1 second goes black.
What to do? need full erase and then install update.zip? if there is way like this. Or need drivers and firmware from computer? to install via USB? I know It's my big mistake.
I have only update.zip
Tablet is with DVB - T, GPS, 1,2Ghz cortex A5 dual.
Tablet called a777
operating system is 4.0.3

new question then. what it's in update.zip? exiting rom update files? not new full rom?

hey! need info!! Can I broke tablet with wrong update.zip ?? maybe other was wrong too? if I'll have gut update.zip for my tablet, it can rewrite new good firmware?

[Q] Bricked Kross GY-601 Chinese Tablet

Hi, I have a Kross GY-601 Tablet... One of the cheap chinese tablet you can pickup at factorydirect (Canada)
I seem to have bricked it when attempting to port Clockwork Mod Recovery to it. It does not show anything on screen or do anything, When I connect it to my computer.. It shows up as M6-CHIP in Device Manager as shown in my image.
The internal storage is completly gone as a result of my failed attempt to un-brick it..
It would be a great help if someone helped me fix this..
Thanks in advance..

PS: I'm only 13 sorry if my description of the problem is a bit bad..

Sooo,
You probably don't have proper drivers, use PDANet ones, they work even with obscure tablets.
You tried to port CWM or flash?
It's not bricked since your computer detects it
Last thing, do you have a backup recovery image or another recovery image that works so you can get it back up?
Daniel

I was dumb enough not to do any recovery image backups..
Also.. I ported cwm then flashed it with dd just poped the .img into the recovery block.. but since I didn't compile it properly when I adb reboot recovery.. It got into a boot loop.. so I tried to fix it but broke it even more... So then I tried re-writing the firmware for generic 4.1.2 chinese tablet.. but that messed it up to the point were it only shows as M6-CHIP.. i can only turn on and off.. nothing else.. no boot no screen light up nothing..

I can help you BUT....

Please Help URGENT!!!

I am not sure what happened to my device I accidentally deleted a system file and many other files like boot and cust I don't know what I was thinking. And now my device keeps restarting and just goes into the screen where it says "Huawei Ascend Mate 7" and keeps restarting on the same scree. So I tried installing a custom rom and that didnt work, I tried to reinstall the backup I made and it kept doing the same thing I saw a thread with a ot so diffrent issue and I tried the method but it didnt work. So please Help me ASAP The advantage is that my phone bootloader is unlocked and I have CMW Recovery menu. SO if there are any methods of fixing my phone and installing the official system update please help me would really be appreciated.
My phone Is a "Mate 7" "Amber Gold" "32GB ROM" "3GB RAM" "Model-TL10"

Looks like you're gonna have to flash the stock recovery and reinstall the stock firmware to get it fixed.
I had a similar problem and going back to (more or less) the phone's factory setup was the only solution.

Bricked MTCD MX unit after upgrade rom

Hi,
My device,
Mtcd Mx
A-Media

While looking settngs page “power off” warning came and after that restart it self, then stuck on nougat logo. Nothings happening just stuck. After i manage a sdcard with sd firmwaretool to downgrade 5.1.1 with stock 5.1.1 dupdate file. Hu stuck on lollipop boot logo no matter what i do.
Things that i tried
With @hal9k 7.1.2 bootable sdcard i can get into Nougat recovery menu, tried clean wipe cash, factory reset options and finally update again, there is no solution still stuck nougat logo.
With stock rom(5.1.1) bootable sdcard i cant get into lollipop recovery menu. Stuck on lollipop boot logo. Tried eject the sdcard as soon as possible when lollipop appears many time, doesnt work.
i never update dmcu, it is same as it was.
İ thing it is bricked, please ineed some advice, i m very sorry for beeing such despered
Edit: i apply this method to flash som with;
1- stock dupdate.img. Flshing succesful but stuck on boot again.
2- flash with sdupdate file of stock dupdate.img. Flashing succesfull but stuck on boot again.
Tried both files doesnt work. İ cant even get in recovery mode.

Would demanding it motivate others to help?
What have you tried and from reading the forums, identified what the options might be?

i dont understand why it always gets in recovery mode with the sdcard which already bricked the unit.
understandings from readings
it doesnt get into recovery mode because it stucks or something went wrong on previous update.
To get in recovery i remove som from board, prepare a cable with 10k and 20k resistors. measure 3.2v from cable. And attach the usb cable pins to som’s related pins. Pc recognise the som, run the rk tool app, load stock 5.1.1 rom. And click restore button, succeed the restore succesfully. Plug the som back to board, push the reset button. it stuck on boot lollipop logo again. İ i tried to restore both dupdate.img and sdupdate.img by one by. Doesnt work.
The only thing that work is the hal9k’s nougat 7.1.2 rom’s sdupdate.img. İt takes recovery menu, i can wipe data, wipe cash , update mcu and update firmware. (Update firmware option only updates nupdate 7.1.2 version which is stuck on boot logo again)
i will flash mcu tomorrow by stlink method. i think mcu is fine. it wont work again.
İ create sdcards with Rockchip Create Upgrade Disk Tool v1.46 (SDBOOT 2.12)

update,
remove som, take it to maskrom mode.
with tool androidtool 2.3
eraseflash
lowerformat
upgrade firmware.
it doesnt work still.
i guess i need fully erase nand partitions and make it as virgin . but how?
installed virtual machine and ubuntu to fix by rkflashkit but, it cant recognise usb

[HELP] Kurio TAB 2 C15100M/C15150M bricked after flashing a TWRP for relevant device (different device, but got the same type of something in Tab)

Hello, I have an old Kurio TAB 2 with model code C15100M/C15150M, I was thinking of rooting it, by installing TWRP. I found a TWRP that was somehow a bit related to the device, an Alcatel TWRP, I think. I successfully managed to unlock the device and flash it using fastboot, but now it doesn't turn on anymore . In no way. It looks like that it also does not charge. Please tell me there is somehow a fix, which is a bit easy??? And by the way, how could it be bricked??? If the tablet should boot into the normal Android OS, it doesn't even use the recovery. So it should be able to boot into the system, which is also quite weird.
