[Q] Can't Boot To Recovery Mode CWM

I'm new to the android community but not new to tinkering with gadgets so naturally the first thing I looked into after getting my SGH T989 was how to root it. Unfortunately, I seem to have screwed something up.
I followed one of the many guides on how to root it and I initially had installed clockworkmod v5.8 something. From there I was able to access recovery mode but when I tried to install zip from sd card, it would let me select the super user zip file but after that it said something along the lines of "This action cannot be done" and I could only choose from the "No"s.
Thinking that I had maybe flashed the CWM wrong, I tried to reflash it via Odin. Everything passed on Odin's side but now I can't access recovery mode at all. My phone boots normally whether I hold down the two volume keys and power key or not. I read somewhere that maybe flashing a different recovery method and then flashing back would help but I can't seem to find another recovery method, all I can find is Odin. Any suggestions?

Anyone? Can anyone at least point me to a download link of another recovery method other than clockworkmod so maybe I could try flashing over it then reflashing clockworkmod? And would I flash it via Odin the same way?

FIXED
Okay I did two things and the problem was resolved, although I'm not sure which issue was at fault here.
First, I did a factory reset of the phone (just through the normal settings menu, since my phone was never rooted).
Second, I learned (from watching a video) that to boot to recovery mode, the volume up and down key must be continued to be held down even after the vibrate from pressing and holding the power button. Previously I had let go of all three buttons at once once I felt the vibrate. I'm not sure if this was the issue or not since the first time I accessed recovery mode I did it by releasing all three buttons upon vibrate.
Anyways, phone has been rooted, I have superuser app, backup has been created, now looking for ROMs. Cheers!

yep you only let go of the power button, you can even continue to hold the power button, but the main thing is to hold the +/- until "SAMSUNG" disappears

Here's what I did, you are correct.
I too was in a situation where my Samsung Galaxy S II AT&T i777 handset REFUSED to boot into CWM recovery mode. This stubbornness was AFTER I installed an Ice Cream Sandwich ROM (my SGS II is rooted and unlocked).
I tried EVERYTHING, including booting in various modes using ICS CWM menu.
I tried renaming ROMS "update.zip" and placing the ROMS in the internal memory and the microSD card root directory.
And I tried doing the manual pressing of keys, which is the original way of doing a "hard reset" from the old G1 days in 2008. I would press the volume up key, while pressing the home and power on keys. Nothing.
After I entered a Google search "my SGS II will not boot to CWM recovery mode" I came to your thread.
I read that you were hold down BOTH the volume up and down, not as I was doing, and as some say, the "volume up."
For about 15 seconds I held down at the same time "volume up/down" (both), the home key and power on key (my phone was off). Voilà!!! It went into recovery mode. I wiped all data, including the cache, said to install zip from SD card, and installed a new ROM (that was NOT named "update.zip" like it had to be on the G1).
So anyone doing a search, that may be the issue, you have to hold down BOTH the volume up and down at the same time, not just the volume up key. Again, that's what worked on my phone, the Samsung Galaxy S II AT&T i777. Maybe it is different on HTC handsets.
Thanks to the OP!! To think I spent about 8 hours on this issue, read the OP's post and five minutes later I had a new ROM on my phone. or is it

Have you tried to ADB into recovery from a computer?

i flashed recovery using Odin..and it worked i can get to recovery using key sequence...(vol + vol - and power) but now i cant even install zip from sdcard or internal sd
i finally could get into recovery but when i try to wipe data/cache it freezes on formatting cache

I can get into recovery but my phone is not starting please help sgh t989
Sent from my Hol U19 using XDA Free mobile app

internal format problems-SOLVED

So i formatted my internal storage before a fresh install, which has sent my phone into a bootloop. I've pulled my battery and manually tried to boot into twrp and the blue "TWRP" screen comes up for about 3 seconds and then i'm back to bootlooping. I have the mjb bootloader or I would odin back to stock. download mode does work, and i tried to reflash my recovery which did pass via odin, but I get the same results. Any help would be great

First don't double post. Second press volume button up, home button then power. When phone vibrate let power button go and keep holding other two anthill phone get to recovery mode.

GUIDE: What to do in the event of "soft bricking" your tablet...

If you have flashed a rom and your tablet "soft bricks", i.e. it gets stuck at the Samsung splash screen or boot loops Recovery there is an easy way to recover without having to reflash the original firmware in ODIN (assuming you were smart and made a NANDROID backup before flashing your rom).
TURNING THE DARNED THING OFF:
Here's the problem. If you are at the Samsung splash screen or boot looping Recovery, you cannot turn your tablet off by just pressing the power button and you can't pull the battery. This prevents you from getting back into Recovery and restoring your NANDROID backup. So here is what you do:
1) Plug your tablet into your computer (this is important!).
2) Hold down the home, volume down and power buttons until you boot into download mode. Once you are prompted, push the volume up button to enter download mode completely.
3) Now, once in download mode, hold down the power and volume down buttons (not the home button this time) until you screen goes blank (your tablet MUST be plugged into your computer for this to work!). Release the buttons and you will see the battery symbol on your screen. Your tablet is now off - thank god.
4) To enter Recovery mode, hold the home, volume up and power buttons down until Recovery loads.
5) Restore your NANDROID backup.
Disaster averted.

Only works if the tablet is off. The key part of this little tutorial is just turning the tablet off when you are stuck in a loop. Once you are off you're golden.

I panicked yesterday because i can't exit download mode with a simple hold of the power key,

Hope this helped.

Thanks.

Lots of new roms. Make sure you check those firmware numbers before flashing folks!

When I was stuck on the Samsung logo for 20 minutes after installing this (beta version) rom a week or so back I did this:
1. Held down the Home, Power, Volume up and down buttons for about 10 seconds, not sure if you need all of them held down, but it seems it force restarts the tablet.
2. After the screen went black I immediately held down the Home, Power, and Volume down buttons to enter into download mode.
3. Flashed the latest XAR stock rom from SamMobile.

If anyone is testing a new kernel keep an eye on those temps. An app called CPUTemp has excellent monitoring. You want to be staying under 100c even when benchmarking.

Almost there but
I did everything you said but when i press the recovery combo nothing happens.It is as if there is no recovery!!!
Help plz.I am furstrated and angry!!!

Ok that all worked fine, but now that I got it turned off I can't get it to go any further than the charging icon is there a way to push files to it while it off? any help or suggestions are greatly appreciated

Same here. Can get into download mode but can't get into recovery. I've TWRP.
Ok made it into recovery.
Update:
I've now wiped Cache and Dalvik Cache and after rebooting it now says Android is upgrading / Starting apps.
Is this a good or a bad sign?

my nandroids were not visible... like,wtf,I can't find any of my backups, twrp isn't showing internal or external SDS...weird

Just bricked my Galaxy Tab S. Got it off and it is showing the battery sign. During TWRP I somehow wiped the internal sd. If I download a T800XXU1ANJ6_T800XAR1ANI1_XAR.zip will I be able to ODIN it back to stock? HELP
Lost my backups
Just downloaded and installed via Odin a firmware version of this tablet and all is well. Just have to start all over again, currently writing this due to a Samsung update for the firmware. YEA!

Thanks a lot. I just registered at xda developers in order to be able to reply and thank you. You saved my tabS 8.4 two weeks ago. However, I lost this thread since that time and I just found it again today after almost 2 hours of google searching. All that to show my appreciation for helping me to switch off my tablet having been stuck at the booting loop.

I would send you money if I knew how. THANK YOU SO MUCH! I had this problem with a Samsung Tab S I got at Costco, and returned it for a new one. That was about a year ago, and I was sure I would have to take it back again. You are uberawesome!

Kindly help me if u can ^_^

Dear,
My case problem is like yours, after I wipe from TWRP I do restart my device & I'm now stuck on Samsung Logo or Battery Logo (if I plug it with my computer).
Now how can I download a new firmware, although I can't open download mode or recovery mode through (Volume Down+Home+Power)?
Thnx n Adv.

You have a couple of options.
1) Do as the guide says. It usually works.
2) If it didn't work, unplug your device and wait until it discharges the battery and goes off. Then charge it from USB, and turn it on with holding down Home+VolumeDown+Power buttons until DOwnload mode appears. Then press VolumeUp, and flash it from ODIN.

[HELP] Unbrick and keep files?

Hey Guys,
I need help here. I'm running (or was running) Euphoria ROM on a Verizon LG G3 with TWRP installed. Without changing/flashing/installing anything new for the past several weeks my phone just shut off yesterday. When I try to power on normal the LG screen comes on then after a few seconds turns off and won't turn back on without a battery pull. Next, if I try to boot into recovery (power + volume down then release and hold volume down + power) and it boots into a "Modified Recovery" that looks like stock LG software but has more options than just factory reset (normal boot / factory reset / wipe cache / safe mode etc). When I try any of these options it reboots, shows the LG boot screen then shuts off and won't restart without a battery pull. I can enter download mode by holding up and inserting the USB while connected to my PC.
Questions:
1) Is it possible restore my phone without losing files/photos?
2) Can I transfer my files to my computer or external SD card before reflashing to stock?
3) What is the easiest method to do any or all of this? LG G3 toolkit? ADB (which I will have to research to do)?
I apologize if there is an obvious place that has this and I missed it. Any links or answers are greatly appreciated!

Is it possible that this is a battery problem not a "brick"? Does the phone boot while charging? My phone had similar problems and the problem was the battery that was faulty.

I originally thought it was my anker battery but I tried with the LG stock battery and it's the same issue. The phone will boot when plugged into a power supply (wall charger or PC) but it just shows the LG screen and turns off and won't reboot.

Anyone? I really want to keep some of the pictures on the internal memory. All I've found is how to factory reset the phone which would delete them but I'd like to find a way to transfer them before I do this. THanks.

U said modified recevery cwm or twrp if thats the case download a random rom place it on your sd card and try to dirty flash a new rom or a otg cable and flash drive

It won't boot into TWRP. It just boot loops the LG startup screen. When i get into normal recovery and select factory reset it doesn't go into TWRP it just reboots, shows, LG screen then shuts off and I have to battery pull to get it to boot again.

If u have a ready linux setup not all people do but it helps sometime i know when i hard bricked it was the only was to save some data for me

Bricked Head Unit RK3188 - Please Help

I recently upgraded to the eonon GA6151 and was trying to flash update_RK3188_1024x600.img " booroondook RK3188" , well I renamed the file wrong to dupate.img instead of update.img I started flashing it and it was too late before I realized. Now the unit will not boot up or go to recovery. I can reset it and see the buttons flash like it wants to go to recovery but nothing ever appears on the screen. Is there a way to adb into this unit? Can I put files on a card and have it auto install them? Any help would be appreciated.

FIXED IT!!
I fixed it using this method. I realized after the fact that this new unit is MTCD not MTCB.
https://forum.xda-developers.com/showpost.php?p=67184851&postcount=50
I then had the error
https://forum.xda-developers.com/showpost.php?p=67309331&postcount=116
Which I fixed doing this
https://forum.xda-developers.com/showpost.php?p=67598154&postcount=319
I used the dupdate from here.
http://huifei.fs-fileserver.de/content/firmware/MTCD Custom ROMS - NOT FOR MTC-/RK3188/2017.02.21/
I loaded it onto the sdcard and the usb drive , the sdcard was created using upgrade disk tool and has to be 16gb or smaller fat 32. The usb drive just had a copy of the dupate.img file on the root of it.
To get into recovery on this unit do the below. http://www.eonon.com/Android-Car-GPS/Vehicle-Specific-GPS/GA6151.html
Press and Hold HOME AND POWER buttons
Press RESET while still holding HOME AND POWER
Let go of HOME AND POWER and then press HOME AND POWER down again and hold until the lights flash 3 times " is about 10 seconds to hold them "
Now Let Go of the HOME button then the POWER button the press the POWER button once "do not hold" and wait for it to boot into recovery.
This is the only method I found that reliably will get you into recovery. Make sure you use the GPS slot for any sd stuff you need to do in recovery.

Did you have to take the unit out of the car? I’ve made the bootable SD but nothing is happening.
