Is there anyone who can explain to me how I can remove Team Win Recoverey twrp v2.4.0.0 and how to install afterwards Team Win Recoverey twrp v2.1.3.
My Acer A500 starts only in the Team Win Recoverey twrp v2.4.0.0 modes.
Backups are on the tablet and on the external sd card but it is not possible to install them.
Error error ......
After a reboot I see: "Secure boot: image checksum Link Fail!"
I want to install ROM "CM10-FLEX_V6Supercharged_Rev2.3_GappsIncl_Public " but this is not possible with twrp v2.4.0.0.
To install TWP 2.1.3-Triumph.zip with twrp v2.4.0.0 gives "Failed".

I tried to install:
- Ezterry A500's Pub Recover
- Thor 1.7.3
- Ra-recovery 3.17 (recovery-ra-Iconia-3.17-GNM)
During a Reboot each time TWRP 2.4.0.0. is the only one to start so I can't install anything else.

I also tried:
- The hard reset.
- The reset with a paper clip.
- Several other ROMs but these do not work with twrp v2.4.0.0. Only ROM "Acer A500 Slim 01-14-2013 (1st Release)" should work. But unfortunately I can only see the ACER logo. Even after 1 night waiting you still see the ACER logo.
- Start all over with "Blackthund3r_A500_A501_CWM_Root_v2" software is also unsuccessful.

I'm doing something wrong but??

I tried:
USAGE-FLOW CHART http://forum.xda-developers.com/showthread.php?t=1816560
- Different stock ROMs. Name change to update.zip
But still, the error message "Secure boot: image LNX checksum fail!"
Only a boot with recovery "twrp v2.4.0.0" still succeeds.
This gives a error message "Unable to locate zip file '/ sdcard / SDCARD: update.zip".
E: Error installing zip file '/ sdcard / SDCARD: update.zip ".
Is there anyone who can help me. It doesn't matter anymore what rom I put on as long as it works.
Thanks for any help

Can you install THOR's 1.73 recovery? If so, then you should be able to flash the ROM you mention, That's how I did mine.
I tried to install:
- Ezterry A500's Pub Recover
- Thor 1.7.3
- Ra-recovery 3.17 (recovery-ra-Iconia-3.17-GNM)

What should I do?

You'll lose all data, so pop out your external micro card, but you might want to try the hard reset...the one where you toggle the orientation button. Have you tried that?
I also tried:
- The hard reset.
- The reset with a paper clip.
- Several other ROMs but these do not work with twrp v2.4.0.0. Only ROM "Acer A500 Slim 01-14-2013 (1st Release)" should work. But unfortunately I can only see the ACER logo. Even after 1 night waiting you still see the ACER logo.
- Start all over with "Blackthund3r_A500_A501_CWM_Root_v2" software is also unsuccessful.

Have you tried flashing a "back to stock ROM". That would also install the stock recovery and remove root. There are XDA threads on this.
Good luck...I hope you get it fixed

I have bricked my ACER and phones several times (and a few times it seemed as if I wasn't gonna be able to restore them). But I always got them running again.
Might take a lot more googling, but you'll eventually figure it out.

Yessss, I did it . The problem consisted of two problems.
1) APX driver reinstalled.
2) Installation on a Windows 7 PC. (Windows 8 will not work)
Then start all over with "blackthund3r_A500_APX_Flash_Tool_v0.4" software.
What a great tool.
Special Thanks to blackthund3r

I will try to install recovery with flashify and my devices can't turn on
It will shows invalid boot.img

Hello,
I have a problem that I can flash TWRP wich works fine. I can go to fastboot. But however I am not able to install any ROMs. Tried Lineage 14.1 and Stock rom.
I tried to flash stock recovery and tried to flash it back by "dload" method - error "Package firmware is not compatible" and when I tried to flash Lineage 14.1, everything seemed fine until boot logo where I was stuck for half an hour before I gave up. Also I am not sure but I think I havent managed to root my phone - tested with "adb shell su" wich gives error messages.'
Even tried hisuite recovery but it said that my phone is not supported.
Tried erecovery wich said "Getting package info failed"
I also can enter stock recovery
Im also getting
Failed to mount /vendor (invalid argument) in olddroid TWRP
and when trying to flash system I get FAILED (remote: sparse flash write failure)
So basically only thing I can do is be in TWRP without root, fastboot and stock recovery.
I have european VNS-21. Used to have stock nougat with EMUI 5.0
Any ideas how to get back any kind of rom?

hi - I hope someone can help me. I have a LTE enabled Lenovo Tablet 2 1050L which I attempted to root using the instructions given here ... https://forum.xda-developers.com/thinkpad-tablet/general/how-to-root-yoga-tablet-2-t3251571 ... but I have managed to brick my device. I successfully installed SuperSU but then read that Magisk was better and tried the same procedure with that but it didn't work. Now when the tablet starts up, I get a message which says ... "EFILINUX ERROR [android_image_start_buffer:737] boot image digital signature verification failed : 0000001A" which appears over the initial Lenovo splash screen. I then get to the Android system recovery menu but I can't get the table any further than this. I have tried wiping data / factory resetting but this does not work.
I can boot the tablet into recovery mode using CWM or TWRP but I have no idea what to do now. I guess I shouldn't have messed. I hope someone can help - I've tried the official Lenovo forums but no one has answered in a week.
Kind regards
I've downloaded this ROM ... lenovo-forums.ru/files/file/1074-yoga-tablet-2-10-yt2-1050l_s100192_151119_row_los-50 ... and flashed this onto my tablet using the Intel flash tool and everything seems to be back up and running.
Can someone confirm that this is safe to do? Can I trust this ROM as it's not from an official source?
Thanks
