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.

[Q] n900w8 Won't boot into recovery mode

A few months ago I rooted my N900w8, installed custom recovery (cwm), and flashed Android L. Today I tried to update the recovery, planning on updating the ROM as well. But now no custom recovery works at all, even the one I had running before. When trying to boot into recovery it says booting recovery... like it should, and then the screen just goes blank, then the phone restarts. Sometimes getting stuck in a bootloop trying to boot to recovery, but usually just regularly booting and boots normally to Android L. So now I am unable to update my ROM because not a single custom recovery has worked and therefore I cant flash the .img files. Please Help!

I had the same issue except when I try to load recovery it would "forward" itself to download mode.
This may work for you, try re-flashing the latest CWM update with Odin. Place your phone in download mode by powering it off and holding Volume Down + Home + Power. Press volume up to proceed.
1. Download and extract
2. Run Odin as Administrator (Download if you don't have already)
3. Select CMW file from your download folder and place it in the "AP" section.
4. Start
When finished, Reboot holding Volume UP + Menu + Power Button. Vola!
Let me know if this works for you.

Yeah depending on which recovery I flash it'll either forward to download mode, get stuck in a boot loop trying to start recovery, or restart and load the ROM.
Unfortunately it still isn't working :/ I used the tool from this page (http://forum.xda-developers.com/showthread.php?t=2446269) to convert the .img to a flashable odin file. Used the proper Canadian touch recovery (also tried recovery without touch) from this page (https://www.clockworkmod.com/rommanager) and no luck. Tried to enter recovery mode, it says entering recovery mode, goes black for a few seconds, vibrates then restarts the phone in regular boot mode :/ Any more idea's?
Do I need to be flashing a recovery that supports Android 5.0.2 for it to work? Im so puzzled.

YES!! Finally I was able to get a TWRP 2.8.5.0 working. Downloaded latest version from the main TWRP site and flashed using ODIN, did not use the converting tool above, downloaded the TWRP as a .tar flashable file from their site. Thanks for the help!
Do I need to close this thread or anything? This is my first time posting on xda

Congratulations on solving your own problem! ^_^
I just figured to share my part when i experienced the same issue. I feel like it has somehow corrupt itself after it finished flashing which results in an empty directory for the recovery mode.

Cannot access recovery mode in lenovo k4 note [newbie]

Cannot access recovery mode in lenovo k4 note [newbie]
Hello,
I recently tried flashing for the first time and attempted to flash my lenovo k4 note with RR-rom 5.8.5 v4.2 (Official).
During the process I managed to flash TWRP 3.0.x onto the phone recovery and loaded the RR OS. However, i was unable to access any internal storage on the device. (Apparently the storage was not mounted or something). I also lost the root privileges to the phone while i was trying to fix the storage issue.
Deciding to start everything anew, i tried to reboot to recovery mode and it never worked. I couldn't boot to the TWRP recovery (1). I tried reflashing the TWRP recovery through adb/fastboot and the process completed without errors. However i still could not access the recovery mode on my phone. Desperately tried to wipe the userdata and cache (as suggested on one of the forums/websites)... but that just cleaned my entire ROM. I now think i've soft bricked my phone where it doesnt move past the "Lenovo - powered by Andriod" logo. All the forums/websites/videos suggest booting into the TWRP recovery but i just cannot access the recovery mode on my phone let alone the custom recovery (TWRP) and even the recovery reflashing does not seem to work. Cannot access recovery from "adb reboot recovery" cmd either.
I've tried everything i could which fits my basic understanding and now am asking someone for help.
--------------
phone: Lenovo K4 note
current ROM: N/A
Root: N/A
Bootloader unlock: Yes
accessed to recovery earlier : vol up + vol down + power btn
problem: Unable to flash and/or access recovery mode.
HELP!

JiaYu S3 TWRP loop

Hello,
I am into a TWRP boot loop.
- I can boot into TWRP
- I can update ROMs
- I can update TWRP
- I can connect to the computer and send files using mtp://[usb:001,003]/
- I can Wipe ...
But when I reboot into the system, regardless of the ROM that I use, I get again into recovery
I have read in some posts that from the TWRP command one could try to clear the first sectors of the misc partition
For instance for a Lenovo ZUK Z2 (Plus) in https://forum.xda-developers.com/showpost.php?p=72298526&postcount=14 it is said that this could help
"dd if=/dev/zero of=/dev/block/platform/soc/7464900.sdhci/by-name/misc"
but ... I cannot find the misc partition in /dev from the TWRP shell ("find /dev -name misc") !
Could someone help me with this one ? I would appreciate it a lot !
Regards

Same problem on MadOS 8.1 (MT6752)!
TWRP loop

Just flash old stock 5.1 Android ROM through Flash Tool. Its pretty easy. Then turn it, turn it off and wipe data. restart TWRP, upgrade TWRP and install new Android 8.1 and gapps. Turn the phone on and its finished. You can do recovery now for the next instalation if you want. I am doing this often because I have same problem for several months. Fortunetaly google backup works pretty fine so its not problem with installing apps again. The command you wrote above doesnt work for me.

I'm having the same problem. I was using my phone today, when it started to show wifi problems (couldn't connect); so, I rebooted it and its screen started to blink; when I rebooted it again, it automatically entered into recovery mode (TWRP). After this, the phone didn't boot normally (MadOS Android 8.1) anymore - only TWRP. Even when I try to charge it, it boots into TWRP mode instead of showing the battery animation.
In my attempts to solve the problem, I firstly reinstalled the MadOS 8.1 ROM but it kept booting into TWRP mode. So I flashed an old Android 5.1 ROM I got (connected and uploaded the device successfully with SP Flash Tools) but it also kept booting into TWRP (now an older version from the 5.1 ROM). Then I uptadated the TWRP and the OS again to MadOS 8.1 but the result was the same.
With any other alternative, I came accross this topic and tried the steps described above (practically identical to what I just did), but again I hadn't any positive results.
What else could I do?

Hello,
I have finally resolved my issue !!!
a) Using "SP_Flash_Tool_v5.1824_Win" and the "RC5_S3_16GB.zip" stock rom I flashed it using ---->>>>> "firmware upgrade" mode <<<<-------.
The option you can find it in Smart Phone Flash Tool, between the "Authentication File" and the table with the partitions.
b) Once done with the flasshing, boot the telephone into the Stock fimware
c) Boot into recovery (power + volume up) and flash the latest TWRP
d) Flash you new ROM
Do not hesitate to ask me if you have questions.
