Can someone please help or toss me some suggestions on how to unbrick my tablet without sending to acer if possible this is whats goin on. It was rooted and running fine with CWM 1.7.3 from thor then the other day i turn it on and bootloop at bootanimation. i then enter recover to wipe and flash as usual but when i goto wipe it says error removing /data/data/com.android........... I heard my data partition was corrupted and proceeded with trying to really format that to no avail fearing my tablet was bricked i followed another thread titled how to unbrick your tablet!!!! it installed OTA ICS and wiped my recovery :crying: so now i have stock recovery and bootloop and the pc still recognizes the tablet in fastboot and APX mode but when i try to format /data in fastboot it says bootloader locked :crying: and when in apx mode when i try to use nvflash it says error during usb write then it says usb device not connected until i restart apx mode fresh. in the stock recovery it will flash OTA packages and finish install but still stuck in bootloop otherwise i just get the dead android guy with a red exclamation point. Any help or suggestions would be greatly appreciated.

Have you tried installing the patched bootloader? Remember, you have to have your SBK number you got from your UID. I found that NVFlashing using one of the earlier releases works best for me.
Also remember what OTA update.zip you are installing. Some of them, are just update patch files, which require a specific OS to be installed.
Did you try this thread?
http://forum.xda-developers.com/showthread.php?t=1699277
Basically, you decrypt the 2 update files, extract the contents of one on to your SD card. Try booting to stock recovery and see if it installs and boots.
If that doesn't work, then do the same with the other update file.
The 50x is basically bullet proof. There is always a method, and sometimes, it's finding the method that works is the hardest.

I did finally get it. I let it bootloop hooked it up to my pc and used adb while it was bootlooping to get my cpuid and sbk since i had neither of those i couldnt do jack with nvflash. After i got those went back in apx mode flashed bootloader and cwm again followed thors instructions on how to really format data partition and installed rom like normal. Worked like a champ, but without cpuid and sbk i woulda never fixed it

then my device stuck at samsung logo
i waited 10 minutes then pulled the battery

its only work when open download mode
and from there i can reboot and turn on the device.
i tried to install recovery again but when boot it stuck at black screen
please help :crying:
When I have bricked a device I either use a computer and adb. You could also use a rootkit . Which is just a graphical adb interface. The idea being - return to stock. If you get there with root and custom recovery - back up. You can then start again with what you are trying to do. I know with the Nexus 6p the Nexus root software saved me.

Then flash your stock rom via odin.
If the phone gets stuck again after flashing a stock ROM, boot into stock recovery and perform a factory wipe.
thanks guys it worked after flashing firmware throght odin

Stuck in a boot loop and can't access recovery mode

So I flashed a custom rom and it required a specific TWRP recovery. But after installing the custom rom I had to install another TWRP recovery otherwise it wouldn't boot into OS (this recovery was probably unsupported and thus my phone was forced to boot into OS)
So every time I wanted to boot into recovery mode I had to use an app like flashify and flash the first recovery to boot into recovery mode. And after finishing I had to flash the "unsupported" recovery again in order to boot into OS.
Now with the "unsupported" recovery, I installed Xposed and some modules and then restarted the device. And..........boom! The phone is stuck in a boot loop! And I can't even boot into recovery mode.
Now here's the other nightmares I'm getting:
1. Cant use ADB to flash a new recovery because my device is "unauthorized" and in order to fix that I need to go to developers option which is not possible (because of boot loop)
2. Uninstall Xposed: button combinations aren't working and I cant go to recovery mode to flash the uninstaller zip
3. vol up + vol down + power button doesn't open recovery because the recovery is "unsupported"
4. Can't even boot to fastboot mode by holding vol down + power. It tries to boot into OS and starts boot looping
5. Can't use sp flash tool to flash stock rom or recovery because whenever I connect the phone to PC, the phone tries to boot into OS and....you guessed it starts boot looping.
Now I'm out of ideas and really depressed. If anyone can help me out with this I'll be grateful forever.
My device is: Lenovo k4 note
Chipset: MediaTek MT6753
Currently on this recovery: https://androidfilehost.com/?fid=673368273298981920
Got this recovery from here (recovery2): https://forum.xda-developers.com/k4-note/development/unofficial-resurrection-remix-5-8-2-t3570195
Thanks!
Update: The problem is solved after flashing stock rom via sp flash tool

I think the pc cant dtect my device same problem bro after installing new rom it keeps on rebooting after the lenovo logo. Cant also access the recovery mode. Please help me
Bro I'm not an expert. Someone from XDA discord server helped me with this. And I actually forgot the exact thing I did to be honest. I downloaded the sp flash tool on pc and downloaded the stock rom. Then flashed it to the phone. You have to connect your device via USB before. For a detailed guide you can search on YouTube with something like "how to flash stock rom via sp flash tool"
Or ask in the discord server. They will surely help you.
How did you flash that? Can you please explain step by step
Check this link: https://firmwarefile.com/lenovo-k4-note-a7010a48
You can download the stock rom from here. And there is also a tutorial on how to flash it. I followed it. Hope that helps!

Thanks, the problem is my phone is struck on the Lenovo logo, it's not turning off but my computer deducted it as Lenovo device
If ADB can detect your device then you can just flash a new recovery and you should be fine. But as I said I'm not an expert so I'd suggest you to ask for help on the XDA discord server. That's where I got help from.
Did anyone found the solution?
Thanks
Can any one find the solution of that problem , because my lenovo k4 note also stuck on boot looping logo... and vibrate like bootup time

i'm without recovery and no o/s installed, pc shows phone as unrecognized dev

so I made a really bad dumb mistake, I flashed over a perfectly good twrp to try a cwm recovery out, and I did so after installing a linage rom not even sure one exactly but I remember reading something about "insecure adb" or something?..anyway, all was ok until the needless recovery flash, reboot after yielded no o/s and worse no recovery partition at all, it just boots straight back to trying to boot recovery, followed by the endless bootloop, I can boot download manually, but now my pc will not recognize the phone at all no matter what I do nothing changes just not recognized. my adb setup was working great I flashed the broken recovery with adb so can someone please offer me a clue as to where to go now cause I'm out of ideas. MANY THANKS for any and all help in advance.
Verizon phone ??
Try Verizon forum .
CWM well out of date and usage now .
I would start by flashing stock rom via Odin .

-PLEASE HELP- UNABLE TO FLASH TWRP OR ROOT

Hello
Sorry for my bad english
a few months ago, i decided to flash my first custom rom (One UI rom) and it worked fine
then i was testing a lot of other roms too until i tried lineage os 20
when i flashed lineage os 20, i decided to try another rom but i was stuck on the twrp logo screen. i tried methods of fixing it but none of them worked.
after trying a method of flashing twrp once again, it failed and i got stuck in a reboot loop and could only boot into download mode. so i booted into download mode and flashed a stock rom.
everything was working fine again until i wanted to try another custom rom. At first whenever i would flash twrp, they would always fail. but later i found the cause of that and fixed it. then, flashing twrp would always pass but my device would get stuck on a reboot loop once again and i had to flash stock rom again.
i tried rooting using auto root but it would show me a verification failed error and i had to reset my device. so now im stuck on a device which cannot flash twrp, nor can it be rooted. its been 1 month and i could not find a viable solution so any help would be extremely appreciated.
You have to just reflash your fastboot rom with fastboot mode unzip it and double click on flash_all.bat file or something like that
it is a samsung, there is no fastboot mode
