however
could you please help.!!
thanks in advances

Can you boot into recovery by holding down the volume down button and depressing the power on button?? If you can, once in clockworkmod recovery you need to select the "fix a500 boot/recovery checksums" under the advanced menu. It should have done this first time you booted into recovery to install a rom or when you rooted and installed cwm. Good luck, and once you get it fixed install the latest cwm recovery that is located on tegraowners.com.
Make sure you try volume up and down to get into recovery since it isn't very intuitive on which button is up and which is down.

Sounds like you have CWM loaded which has a tool to fix checksums. You boot to recovery mode using power * volume+ and then in the Advance menus is a item to fix your problem.

I had the same issue a while back. If you do not have CWM installed, you should revert back to a 3.0.1 original ROM. I am not sure if 3.0.1 is required, but the original ROM from acer has a Windows Flash utility, so the tab is flashed using a PC, not the recovery mode from the tab itself.
It was a while back (before this summer), but i can't exactly remember if my tab already had CWM or ROOT.
I know there is/was a thread about reverting to 3.0.1 somewhere on XDA, but i can't seem to find it anymore.

Boot to recovery. Hold vol- and pwr until text appears at the upper left corner of the display.
Can you do that? And get the menu?
Say exactly what you did, with filename. All procedures you did.
We are missing information.

[Q] TWRP: "custom recovery" not working anymore, TWRP not starting

Hi there,
I wanted to install latest CM10.1 coming from 0526 yesterday on my Defy+.
Did a backup with TWRP first.
Then the flashing failed, so I wanted to recover from backup.
Phone now is stuck at Motorola M not booting anymore.
When I enter bootloader (vol down) and want to enter "custom recover" he just jumps back to the same menu. TWRP is not starting.
Choosing "stock recovery" is possible, but if I choose a CM10.1 zip file it's not accepted.
RSD Lite does not recognize the phone when it's in the bootloader menu or in the stock recover menu.
Help is very much appreciated, what can I do?
Thanks and best regards.

Okay, I found out why I couldn't enter flash mode by using Vol+ when starting.
The phone powered already up when I put in the battery, so I always pushed Vol+ too late.
Pressing Vol+ WHILE inserting the battery did the trick, phone went into flash mode and I could re-flash 2.3.6 sbf using RSD lite.
[Idiot mode=off]
Still not sure why TWRP was messed up just by recovering from a TWRP-made backup...
Best regards

Same situation to me.
I opened Terminal Emulator, gained root access
then type below command to get recovery mode
# reboot recovery

Custom recovery not running
I have a similar issue.
I rooted my stock S4 and installed the proper TWRP.
Heres where my situation is a bit different from anything I have seen on the forum threads. All attempts—both hard and soft—to reboot into recovery, all direct the reboot to Odin Mode. Just to clarify I have not flashed any rom custom or stock, the only thing I have flashed has been TWRP and CWM recovery. And I only flashed CWM AFTER the Failings of TWRP.
When I attempt to boot into recovery, it flashes the blue characters then sends me into a Odin Mode loop until I hard-key the "download mode" and select restart to boot the os normally.
my phone works fine other than not being able to flash custom roms, which is a pain in the arse especially with all the s4 Bloatware.
Here's what I have done so far to help myself:
• install CWM recovery
• tried hard-key reboot recovery (power off/ press home/volume up/power)
• soft reboot recovery through both Goo, CWM and ROM Toolbox pro
• removed my sd card and tried reboot recovery
• removed battery and reboot recovery
• emulator reboot recovery
• reboot recovery both with and without usb cable
I looked into flashing stock with Odin but all tutorials i could find were of an older version and I didnt want to guess what I needed to get that to work,
Please let me know if theres anything I can do.

Phone boots into recovery mode on power on

Hi there,
I have just tried to flash cyanogenmod onto my note 3 and must have done something incorrectly. Now whenever I power on the phone it goes straigt to recovery mode after a 3 line message about seandroid not enforcing. I can also boot the phone into download mode. I am using twrp recovery and whenever I try to flash the cyanogen zip file it fails saying e: unable to mount '/usbstorage'. before I orignally tryed to put cm on I created a backup with twrp and I have restored this, and this is the stage I am at now.
I am really stuck now and need some help please.
Thank you

Home-Volume Down-Power = Download Mode
Home-Volume Up - Power = Recovery Mode
You'll need to flash the Bootloader and Recovery. It may start up at this point. If not, then flash the Singapore ROM. You can extract the bootloader and recovery and then make them a .tar .md5 file for Odin. Read about it HERE. I've used it to recover my Canadian SM-N900W8 Note 3. All it would do was vibrate and boot loop. Now I'm 100% back up and running in Lollipop. Only use files for your version of the Note 3.

Singapore has 4 cell providers to choose from.
Or
you can try using Samsung Kies . Tools > Emergency Firmware Recovery. You'll need the serial # under your battery.

Or you just flash this one https://idlekernel.com/twrp/3.0.0-0/twrp-3.0.0-0-hlte.tar.md5 by Odin on the AP slot. If you really have a SM-N9005 like me (No other strange SM-N900* one!) this will work and fix your loop by updating the bricked recovery to the most recent TWRP one. Here is more information I'd recommend to at least read a bit of to at least understand a bit what you are installing by that: http://forum.xda-developers.com/showthread.php?t=2467001

*Help* Phone keeps on booting into TWRP and then doesn't respond.

I just flashed TWRP for the first time but it comes up with "Unmodified System Partition" but touchscreen doesn't work for some reason so I cant select anything. I tried removing the battery and rebooting my phone (Galaxy S4 19505) But it just boots back into recovery for TWRP in the "Unmodified System Partition" . Please Help, thanks.
Edit: Should I delete the TWRP disk image from my pc? (My phone also keeps vibrating while turned off). I have also noticed that there is a non physical home back and menue button, did I download the wrong version? I used the TWRP app to download and flash the image.

Hi,
Download the latest image or tar from here: https://dl.twrp.me/jfltexx/ and flash it with either Odin or Heimdall.
Not quite sure about the notice, is it on the screen that asks you if you want to keep the system partition read-only? Then you either need to swipe or click ok.
Normally flashing a recovery should not produce the problems you are describing, did you only flash the recovery?
