hi all been a while since i been on here but find myself in bit of a pickle.
my dad gave me his old android tablet for my son to play but its not working like the os has gone from it all it does is stay on the main screen with the android or i have been able to get into the tablets default recovery mode where it asks things like apply update from zip or apply update by adb etc etc. the tablet in question is an avaco stb7012 v1 and i know its a cheap ebay china knock off just looking to flash it but cant seem to get anything to work in order to flash anything on there anybody have an idea ive tried using commands like fastboot and adb but says device null on adb and fastboot it says waiting for device and nothing happens. am i doing something wrong is there a guide i can follow to do it or is it naff coz i thought as long as it does boot into recovery then there is some glimmer of hope i dont no what else to do spent hours researching any roms for this tablet but nothing. hope someone can help all i want to do is be able to install a new os of android onto it and get it running again.
thanks

Hi everyone! As stated in the title my phone(p769) wont boot completely, I was in the middle of doing the bootloader unlock when I accidecntly replaced the bin during the root process of it with the wrong bin. Instead of replacing it with the v6 tmobile usa one I used the v5 canadian one. Now when I boot my phone up the lg screen is there and then eventually it just hits an android with a red exclamation point. I've tried Re-flashing while its in s/w upgrade mode with the flasher set to emergency, and Ive tried pressing the home button + vol down + power to no avail(it goes through the process but the same thing happens)
Any help at all would be greatly appreciated and many thanks in advance!
Edit: Also when I try to reflash, it just says it cant communicate with my phone. Ive uninstalled and reinstalled the drivers several times but seeing as how I cant acutally get into the phone Im not sure what else to do.
Edit 2: So ive been trying do something witht his for the past three hours and I cant get anywhere with it. I cant get the phone to show up as an adb device while its in s/w upgrade mode, and at the red exclamation point screenit shows up but as recovery and the lg tools fail to communicate with it. I would really appreciate if anyone knew how to deal with this.
Just in case anyone stumbles upon this and has the same issue I would like to say that i finally got mine fixed.
It has been a long day of frustrations but I finally got it there with the help of some awesome tutorials.
In order to fix it I had to fastboot my phone and flash the default loader and boot then my device would show up in my adb devices and I could sucessfully flash and root it.

I followed the fastboot tutorial and searched around in the help forum for people with similar issues and found a post where lelus posted both of the files I needed to flash with fastboot, from there I just put my phone in s/w upgrade mode and followed Lelus guide for root/flash
So this is my problem.
My friend told me that chainfire 3d probably would prevent lag on my phone when watching HD videos and I installed it without further research. As for many other people that I've read about afterwords my phone got stuck at Asus loop and then went strait to recovery startup screen and I can't seem to get anywere from there. I've tried sooo many different guides and tutorials by now so I finally decided to seek out help here by posting this. In one of my weakest points I desperately tired to do a factory reset but that turned out to wipe my whole phone so all that exists now is an empty folder named "asus_log" in my "/data/media" dir.
This is what I tried so far as I can remember from the top of my head.
Tried getting it going via fastboot but that function doesn't even work at all. (No fastboot available )
Used all adb commands I can find in other guides. I see my device through "adb devices" but when I use the shell command it just give me an error. The same with the "su" command.
Tried to use the "push" command with a stock rom but it just get stuck and doesn't proceed.
Tried using ODIN but that's just for Samsung.
Used android sdk and installed all kind of **** some tutorial proposed.
As I live in Sweden and we don't got any asus stores it would be a pretty expensive thing for me to go to a computer store that is an asus retailer cause they have to ship it to some other country for repair probably.
So I would be sooo happy and grateful if anyone here knows the solution for my problem and would be able to help me, please!!
So, for Christmas my daughter's mom got her an A33 Q88H QuadCore Softwinner tablet, and we discovered the OS it came with had some very strange issues related to a lack of compatibility with Google Play, so I tried to get around that with software, but I needed to be rooted. However, I had bizarre difficulties with SuperSU, unlocking the bootloader, rooting, and even more difficulties trying to flash a custom recovery that I could use to ROOT-- the obscure china tablet had no TWRP or CWM support. I finally tried a very convoluted method of flashing what appeared to be a ROM for the A33 Allwinner tablet, which hadTWRP already installed, so I could use TWRP to root it, and then finally fix the software issues.
However, the process didn't work, and when I rebooted the phone, I found it stuck on a black screen with a tiny android symbol, and that's how it's been since. Holding volume and power button only reboots it to the same screen -- no bootloader or anything, so I can't find any way to try to flash a factory ROM to get it back to regular settings. When I plug it into my computer, it makes the input noise, and shows up in Device Manager as "Android Device" with "Android ADB Interface" drivers successfully installed, but ADB doesn't recognize it as a device, and I can't get it into any sort of download mode -- it isn't recognized in My Computer as a hard drive. So, I can't find a way to interface with the tablet to reflash a stock ROM. :frown:
It's her Christmas present, so I don't want to admit that I've broken it; I've been trying to solve it all night for 12 hours straight, but I just can't find anything that works! Is there any way you guys can help me? :crying:
I tried to attach some pics but the uploader isnt working.

Hi All,
I have a Huawei Enjoy 7 - Model SLA-LA00 (running Nougat 7.0, EMUI 5.1, Boot is unlocked).
I'd like to root it, but I've tried Kingoroot, King Root, iRoot etc and it repeatedly fails. On checking it seems that my device isn't compatible with those apps. I would like to use the ADB method, but there's no custom recovery image for the SLA-LA00, I've also checked and it seems, there isn't but please correct me if I'm wrong.
Is there a custom recovery available for my model?? Also, I've tried looking but, is there an International firmware for this model??
Any assistance would be appreciated, thanks.
Regards,
marquez010
Hello, was going to create a new thread, but think yours fits what I need to ask aswell.
Same phone here, bought it in Shanghai and now in Brasil, was trying just to make it google able. Salesman at the official Huawei store tricked me to think it would just need access to a open network for it to work. Silly me.
Well, as you, unlocked it with ADB and with no answers from nobody, tried to flash it with a random TWRP. Obviously didn't work. Now the phone wont boot into system, but i still can manage to put it in fastboot mode and it still replies to ADB.
Question is if someone that knows better than me can tell me what to do to at least get back where I was, before I finish killing this damm stupid phone, wich also doesn't seem such bad idea.

Hi , all you have here :
https://www.getdroidtips.com/huawei-enjoy-7-b161-nougat/
Hey, thanks a bunch. Found that post before, but it looks like its for an older version of this phone. Mine was running b190 nougat. Don't know if should try to flash this one, but if no other ideas, will try it.
Well, was able to boot it again. Flashed it with yet another twrp that i found for a similar (or so i think) huawei and even tough it didn't work, when I connected the phone to the charger and it responded the power up volume combination and allowed me to reboot normaly.
Guess I'm back to where I started. Think now is better to wait, maybe there wiil be a moe suitable release of a gms core package that it requires for google play to work (have it, but installation fails on rebbot) or twrp updates with a version that works for me and then I can try to install gapps thru it.
Back to my old crappy lg now.
So I admit I am an idiot and did this to myself. I installed the latest FireOS OTA through TWRP then thought to keep TWRP I would install it before I rebooted. I know I probably should have read threads about keeping root and the horribleness of 5.6.0.1 but I did not. So I can boot into the OS and I can boot to bootloader but I have no recovery at all. Any one know how to recover from this? Found out the unbrick method I have used before does not work. Fastboot give me an error about locked hw.
Been working on this anyone know or have a fastboot zip or image. I am getting a errors trying to flash the amazon bin with fastboot.
I know I am the only one posting here. I read through a bunch of threads that seem to be people in the same issue. I have now managed to get it stuck in demo mode. I also cannot seem to accomplish much from fastboot because I get a locked hw error. Bought a couple for parts HD6s off ebay. So hopefully I can make something work and get at least one working tablet. This has really put a damper on trying to create a device tree to try and build cm12.
Closer to being a brick. Some how I managed to have root in adb and managed to wipe all. Which I guess really meant all. Now all I get is the amazon logo. No desktop. No adb. No way to get to fastboot.
So ebay tablets came in, bout a lot that had 2. The one was listed as a demo model, so a simple ;demo in the search and resell the device and viola fully working tablet. It still had 4.1.1 on it so a simple update to 4.5.3, Kingroot, and TWRP install and back on CM11. The second was "black screen" so I assumed bricked as it did not seem to turn on when plugged in, initially. Tried running through unbrick but nothing from ./reader.sh so assumed on newer FireOS that blocked that function. After setting the first up I was rearranging my stack on now 2, what I thought where, badly bricked devices. Hit the power button and booted to lock screen with 7% battery. So I now have an extra HD6 to mess with. Best part is I got both of them for $20 total.
