[Q] Can't Start Stock recovery mode - Eee Pad Transformer Q&A, Help & Troubleshooting

Hi
Just Today i noticed that i can't start my Stock recovery mode, I am currently on 8.6.5.21 stock Firmware,
The only thing i did was rooting the Device using NachoRoot and i did not Have any problems while rooting, everything went very smoothly, i rooted the tablet and then installed the superuser app, after that i did batch Backup using Titanium Backup and finally installed rootkeeper
A while ago i tried to boot to recovery mode then i got the picture of the Android with the exclamation mark ( ! ) inside of it.
I would like to know wither this is normal after rooting or not because before i never really tried to boot to stock recovery mode.
if not is there anyway i can retrieve the Stock recovery mode?
I mean as far as i know almost everything you'd want to do you'll have to do it using whatever recovery mode you have.
If there is anything you can help me with, it'd be much appreciated.
Thank you​

come on guys 35 views and not a single answer
at least someone tells me wither it is normal or not

Seems normal to me unless you have something on the Microsd that you want to flash.

so what you are saying is, i have to have a micro sd card inserted with something to flash in order to boot to recovery mode?
I mean what if i want to wipe the data in the device or restore factory settings?
I don't really think it is normal, can anyone please confirm it?

He is right, that is normal.
That is your stock recovery. The stock recovery doesn't do anything except scan for an update file. If it detect one it flash it, if not you get that Android with exclamation symbol. while holding Vol down plus power button and wait till you see the prompt, if you push Vol up within 5 sec it take you to recovery but if you wait a little longer you'll get a prompt to either wipe data our cold boot device

No Recovery, garbled screen, can I recover?

I rooted my TF101 model B80 using RazorClaw (nvflash is a no-go for this model). Installed CWM, all was well. I tried to install Prime ROM from CWM, and was unimpressed; tried to restore my Nandroid backup of original rooted OS. Now, Transformer will not boot into any recovery (neither CWM or original green android), and screen comes up garbled. Is there any way I can restore my original stock by merely putting a particular image on my external sd card?
Any other suggestions welcome, I just can't get to a screen (recovery or otherwise) where there is any readable text I can respond to. Nor can I turn the device off. It will continue to reboot in this fashion. When I get home today I'll be able to start from a dead battery.
Thanks
Did you wipe before restore?

Yes, I did a full wipe including dalvik cache before all restores. At this point, though, my primary concern is just finding a path back to usability!

I had the same situation..I used the unbrick method:
http://forum.xda-developers.com/showthread.php?t=1123429
then you could try restore a backup ..
To turn off the device press the power button for 10-15 seconds..

I can try this when I get home today.... I'm just concerned because the method involves nvflash .... which I thought didn't work from the newer TF models (I have a model B80). I needed to wait for the RazorClaw exploit because previous attempts at using nvflash failed....
Then NVFlash will fail still...

Being you can't get back into CWM not sure how you'll flash the stock kernel.
HAve you tried Holding Vol Down button plus Power button till you get prompt to enter recovery at which time immediately push Vol up button withion 5 sec.

OK .... my bad.... I guess I wasn't pressing the buttons in the right sequence/duration. I CAN get to CWM!
So, once again, I try to restore the Nandroid backup and after rebooting, end up with the screen situation as in the reference you provided.
So, I am assuming my Nandroid backup is not restoring the kernel that it needs. I was running a recent OTA update; I believe the version was 8.6.5.19.
Where can I get the appropriate kernel to install from CWM? Does it matter in what order I install the kernel and the Nandroid backup?

Same issue, no recovery though
Hi,
I have the same issue as the original poster, B80 serial, RazorClaw root. However, when I boot to recovery I get the green android with yellow triangle and exclamation mark.
I need to restore a recovery on my device as I may need to unroot to send to Asus. I have an even deeper problem of having to have the device connected to power for it to turn on after shut down.
However my main question is for that serial number and root method, what is the best way to flash a recovery on my device (stock or CWM) if I can not get into recovery to begin with?
P.S. RecoveryInstaller will not work, after installing the apk, I click the flash recovery button, the system holds for a bit, then nothing happens.
I will continue to search the forms for some answers, any insights or direction will be appreciated.
I can get into apx mode.
Thank you community!
I think you can flash the recovery via the staging partition. Search around the TF section, it's in here somewhere. Although, I wonder why the 1 click recovery didn't work?

Everything I see in the forms requires one of several conditions which my TF doesn't currently meet.
1. Recovery. I can not go into any recovery, thus I can not perform any flashing of any other rom or recovery.
2. B70 or later. Because of the security in the boot for these new serials, I can not use the NVFlash tools to un-brick / flash.
I am already rooted, however I do not know the reason for lack of recovery on this device. I unfortunately bought it yesterday from Craigslist, so not sure what this guy did before I got it.
I searched for flashing recovery staging partition and did not find anything immediately relevant. Please advice is there is a different wording I should use in my search as I am now getting an immense download on all of this trying to figure out what to do. I am also fairly new to Android devices having 1 other phone that is rooted.
Thank you for all the support and quick response! wonderful community here.
Try searching for posts with /dev/block/mmcblk0p4
This is particularly dangerous because you don't have access to nvflash. If you get bootloops, it is bricked. You have to be sure that whatever you flash will be 100% compatible with what you have now.
Also, when you try to boot into recovery, what does the text at the top say? There should be a version number in there somewhere.

Thank you gee one. I have since been able to install clockworkmod. My issue with the power not turning on if not plugged in still persists, I have started a separate thread.
I found your post on the staging partition here:
http://forum.xda-developers.com/showthread.php?t=1309949&highlight=power
Do you recommend this for the issue still persisting?
If so, considering I am on 8.6.5.19 will I have to use the blob from that? It is not on Asus website as I got it from the firmware update option in the settings before loading up my new ROM.
Do you recommend this step as the only resolution or is there another way?
Ok let me get this straight:
You have clockworkmod installed. Can you boot into it and do the buttons work?
Are you getting a garbled screen when you boot into the rom? Or are you just trying to unroot?
The tricky part is to avoid the bootloops of death.
sent from my cyanogen(mod) vision
Honestly what i would do if i were you, assuming i understood correctly that you can get into clockworkmod, just reflash the prime rom you didnt like(after wiping everything, including cache and dalvik), and if it boots and everythings okay, at least you know nothings really wrong with ur tablet. As for the plug in situation, make sure your battery isnt simply dead. As far as i know, it wont charge from recovery, so if uve been stuck without a booting rom for a while, it being dead could definitely be possible. Once you are in a working rom and you sorted out the charging issue, then you should worry about getting back to stock.
Thank you camaros,
I am able to load stock ROM successfully.
Battery is not dead as it is fully charged, and will run un tethered after powerup. I will test resetting it although I doubt that is causing it.
What i would like to determine is, is this related to a hardware or software issue?
Also, is there a way to restore stock recovery from CWM?

[Q] HELP! lg g2 stuck in boot loop

I have an at&t LG G2 D800 the android version is 4.2.2. my phone is ROOTED and I do have PHILZ Recovery. I was trying to do a hard reset or factory reset not sure what the difference is. what seemed to happen in the process is my phone was almost completely formatted and now i have access to only download mode and I can get into Philz Recover still. other then that when i boot my phone up it just gets stuck on LG boot up screen and my LED notification light blinks. need help please. cant seem to find solution or I just haven't looked in the right place yet. if anyone knows how to help or at least point me in the right direction. I give huge thanks in advance.
So you have a custom recovery installed. Good! Head over to your phones forum section and look for a stock ROM if you can find it.
If not then find an aftermarket one. Once you have found one. Download the needed files. Some included Google apps and some don't. It'll state it. Download the two zips or one if everything's together. Boot into recovery mode on your phone, and select storage and mounts.
From there go to the bottom or look for mount internal SD card or external SD card. Mount it. Then transfer the files you had downloaded to the root of your phone. Once done. Un mount it and remove the cable. Go to the menu of the recovery, select factory reset option. Then install the .zips.
Your phone should then boot up. Something must have gone wrong when you had done a hard reset.
Reply back when you've done the above. And tell me how it went.

Thank you for your help. my download speed is horrible so i'm in the process of downloading the two zip files for going back to stock. ill let you know when i get them downloaded and if it works.
Okay, good luck!

I have the same problem. I was running 4.2.2 rom under twrp recovery. Then I flasher Philz and flashed 4.4.2 rom. I was unsatisfied with it so I flashed back the old recovery so I could restore the backup. I booted twrp, recovered the backup and reeboted the system. After booting it was saying some crap like this and that procces stopped. Now Im flashing the .zip (just downloaded rom, no data), and after that its there just the boot loop (lg picture and blinking LED). Please help what to do :good:
you should flash via download mode with kdz file to go back to stock
I don't know if it's better etiquette to semi-hijack this thread or post a new thread, but I've created the same problem for myself today. I instaled TWRP recovery successfully and downloaded a CM11 nightly along with gapps for CM11. Today I installed the zips but when my phone rebooted it started the endless LG logo loop thing, which sounds the same as he describes.
I can't seem to boot into my recovery with any key combination. Volume up and power, volume down and power, they all lead to a "Hardware Key Control Mode" menu. At this point my goal is a factory reset. Maybe the same solution that helps him will help me? I need to get the phone into either download mode or to the TWRP menu.

[Q] Recovery Boot Loop Problem

Had a problem. Hope someone with experience can give me a few answers.
Nave new t-mobile Note 3, SM-N900T. Stock 4.4.2 KitKat Touchwiz rooted.
Rooted to enable SDFix to use SD card as I want to use it.
Everything great! No problems.
Thought it would be wise to have a Nanoid backup.
Opened Rom Manager and made One change in prefrences. I set it for external SD card storage. (mistake?)
Went to 'Backup current Rom' in Rom manager, started it and it started to reboot. Shut down and restarted in a 'Recovery' boot loop??
No matter what I did, Tried holding power, up volume and home button, nothing. Boot loop continued. Removed battery, waited, as soon as I re-installed battery it instantly went back into recovery boot loop.
I don't know what I did, I kept removing battery and trying again and again and all of a sudden, it booted up back to KitKat and now everything is working great again. No problem on any standard reboot.
What happened? I have used this same set up on my S3 and never had a problem.
I would like to backup the current setup for any future problems. But now, I'm afraid to even try.
I removed Rom Manager and re-installed. Made sure that the storage location was reset to internal and it should be OK??
What did I do when I got out of the Recovery boot loop??
So, afraid to try again. Don't want the boot loop again.

Hi. What recovery are you using?
If you haven't installed a custom recovery, then that explains your issue. Basically, the app scheduled a custom recovery script which kept failing in the stock recovery. You should normally be able to reboot into the system holding the power button, thus skipping going to recovery. This also resets the recovery script so everything is back to normal.
Nandroid is normally only possible using a custom recovery like TWRP or CWM.
I saw that you might be able to perform a Nandroid without restarting the phone (so without a custom recovery) using this app: https://play.google.com/store/apps/details?id=com.h3r3t1c.onnandbup&hl=en
I have never tried it. Looks promising though.
But please note that you won't be able to restore the backup without a custom recovery.
EDIT: If you do have a custom recovery, why not boot in recovery mode and make the backup from there?
Cheers
Recovery Boot Loop Problem
I have CWM installed. Setup thru Rom Manager as I have done before on other phones.
Tried it again, same thing. Over and over. Constant reboot. Dosen't matter if I hold the power button or try different ways, same thing.
It says: Recovery booting
Recovery is not seandroid enforcing
Set warranty bit:recovery
If I remove battery and wait a couple of minutes, I can install battery and it dosen't start till I hold power button.
So I held volume down, home button and power button and booted into download mode. From there I cancelled and it rebooted normally.
Everything I've read on boot loops always say 'boot into recovery'. I only wish I could. That's the bootloop.
Any idea on what's wrong?
Thank you for your time and trouble.

Have you tried booting directly into recovery?
So just shut off your phone and then open it by holding volume up + home + power. It should boot into recovery. If it doesn't, I recommend installing cwm or TWRP using Odin instead of Rom manager.
Might be a problem with your current recovery.

Yes, I tried. Does the same thing.
I've never used Odin. All the info I've read mentioned downloading USB drivers and using different .tar files. Checking this and that.
Nothing I've ever done.
No experience with it.
Never had a reason before to use it.
Every instruction website I've read all seem to be different.
I'm gonna have to find out, huh? lol
I've got Odin on my computer, and have the CWM 6 zipped file.
Will do some research.

No problem.
A few tips with odin:
-If you have Kies installed, you don't need to install other drivers.
-The file you flash with Odin should have tar or tar.md5 extension
-you have to activate USB debugging from developer options.
-boot your phone into download mode
-run Odin as administrator
-connect your phone. you should see the text Added in Odin. If don't see it, you need drivers.
-you should make sure only auto reboot and f. Reset time are checked
-you should put the file in Pda or Ap(if using latest version)
Click start and wait until it finishes. It will restart itself if you checked auto reboot.
That's about it. It's very safe and easy to use.
Watch some videos on YouTube. You will definitely find some.

Something is stopping the recovery boot. More research ahead.

Strange. You could try TWRP instead of CWM. I use TWRP and really like it:
Here is the download link for your device: http://www.techerrata.com/file/twrp2/hltetmo/openrecovery-twrp-2.7.2.0-hltetmo-4.4.img.tar
This is the Odin flashable recovery.
Here is TWRP page: http://teamw.in/project/twrp2/
EDIT: One more thing. Are these the exact steps you are following when booting into recovery?
"To access recovery mode on your Note 3, turn off the device and press Volume Up+Home+Power buttons at the same time for about 4-6 seconds. When the screen lights up and you see the Samsung logo, release the Power button but keep Volume Up+Home keys pressed until you see the recovery menu screen"

Yes, if I use the buttons, the download mode comes up saying 'Boot failed'. That's holding the vol. button 'up'. If I hold vol. down, it loads download mode correctly.
If I try to enter recovery thru Rom Manager, Recovery tries to start and the boot loop starts. ??
I may try TWRP. I've heard a lot about it.
Thanks for the links.

[Q] Can't get to recovery after (successful) upgrade to KK.

Hi,
just got time to update my 2nd XT925 to KK (RSD'd back from CM11 JBBL to stock SFR rom, let the phone find its update and apply it, everything went fine).
But whatever KK recovery I try to flash, it gives me an exclamation mark and nothing else (I'm unlocked, yes).
Don't know what's happening here. Can someone helps please ?

Are you saying you are trying to flash a recovery or are you trying to GET to the stock recovery? If you are trying to get to the stock recovery, the key presses to get to it have changed.
Your best bet is to power off your phone. Then, press and hold power+vol up for a few seconds until you see the menu come up. Then, press vol down to highlight Recovery and then press the vol up button.
Eventually, you'll see the "Dead Andy". From there, press and hold vol down+vol up+power. You might have to do it a couple of times. Eventually, you'll be in the recovery but for the XT926, it's kind of hard to read because for some reason, they decided to make it dim.
No (but thanks anyway). What I tried to was only to install a KK recovery for CM11.
I successed but I had 2 problems mixed: the 1st one was that the Linux version of fastboot (or mfastboot) did'nt work with the new bootloader. Both were complaining about "(bootloader) Variable not supported! ". Had to find some old laptop with Windows installed to use it to flash the recovery without error.
But even then if I just let the phone reboot, I would'nt get the new recovery (just the stock one after the keypress you speak about). I had to go straight from bootloader screen to the recovery (by manually rebooting) to get it work. Looks like the standard boot just restored the stock recovery each time I tried.
Thanks anyway, it's working now.

Variable not supported comes up under some Windows, but it usually still works.
You never go straight to the bootloader when you reboot. You have to reboot the phone (or turn it off first) and then press and hold vol up+power. Then, from there, you use vol down to select recovery and then press vol up.
It never boots directly into the recovery unless you tell it to via an ADB command or from within a custom ROM that allows it.
Keep in mind, the stock recovery will override the custom recovery if you don't immediately boot back into recovery. Flash recovery, when that's done, press power to shutdown, and use the method Bolski described to boot into recovery.

Let me see if i undestood.
You say that if you don't boot right into recovery, the stock one will overwrite CWM/TWRP. So i understand that, after very reboot you must reflash recovery if you want to use it again.
Or am I missing something?

It won't reflash every time. You only need to boot straight into recovery the first time, so that the update binary completes. After the first time, you'll be good.

I think this may be the problem I am having. I cant get my 926 to boot to recovery from fastboot after I load CWM recovery. Is there some trick?

After rooting my nexus 5 is not booting up with non stop booting animation

I have a nexus 5 16 GB and i downloaded the recent software update android 6.0.1 and then I decided to root and I used 'Nexus root toolkit v2.06' and first unlocked the bootloader and then rooted. Everything worked fine but after the process was complete it was rebooting and the booting animation went on and on for many hours and the device did not root. I really don't know what's going on. My purpose is to install a custom rom: cyanogenmod 12. Now what should I do ???? PLEASE HELP. When i try to enter recovery mode it shows a picture of the android mascot with opened back and exclamation and cannot enter command as well. and after some time the booting animation begins and goes on and on...
please help...

Unless something has changed, version 6. requires that you flash a special kernel before you can root your phone otherwise you are as you are now, stuck in a boot loop. You should probably download the factory image from Google, and then flash the system image to get rid of what you have done.. Perhaps then your phone will start normally

Also, you mentioned a 'special kernel' what does that mean. All i want to do to my device is install cyanogenmod 12 and for that i believe it needs to be rooted, so i am really confused. What should I do know
I'm having this same problem, and unfortunately, when I start the phone on fastboot, I can not access the recovery mode in order to upload a factory image of nexus 5.
I used the new tool available her for quick flash, and now, I don't have a phone.
First, don't panic. Your phone is still very easy to recover. Unfortunately I can't get you a complete walkthrough here (for now at least), so I'll give you the main idea and you'll have to do your homework (as maybe you should have done before).
1. You need to get fastboot working on your computer. It's included in the Android sdk package, but there might be some easier way to get it. Google it. You might need drivers for your pc too. Google it as well.
2. Then you need to get into fastboot mode on your phone. To do it, hold down power button AND volume down button until it gets into fastboot mode. You will see an android on his back with the cover open. At this point, connect your phone to your pc, open a terminal on your pc and type "fastboot devices" without the quotes "". It should find your phone if fastboot is working. If it doesn't work go back to step 1.
3. Download TWRP recovery on your pc and place the img file in the same folder as your fastboot executable (not mandatory but easier). It can be found here https://dl.twrp.me/hammerhead/
4. Always in fastboot mode, type "fastboot flash recovery twrp-2.8.7.1-hammerhead.img" assuming you downloaded that file, which you should have by the way. It should install fine. If you haven't placed the file in the same directory as your fastboot executable, you will need to provide the path to your img file as well.
5. Then use the volume rocker to switch between modes and choose reboot recovery.
6. You should now be in TWRP recovery. At this point, download a custom kernel (anyone found on xda for hammerhead should do) and push it to your phone. It should be fairly simple with TWRP. Then flash your new kernel using install. It should help you get your phone booting normally. Alternatively, you can download a custom ROM like cm12.1 and flash it altogether. It will install everything needed for your phone to boot up too. Beware if flashing a ROM though, I strongly advice you to do a factory reset before flashing it. You will find that option in the wipe menu.
Hope it helps, let me know if you need further assistance.
Yesterday, I have tried everything to have my computer to recognize the "fastboot" command, and I installed like 2 or 3 different programs for that. With my old Windows 7, I have been able to push a flashed image to fix this issue, using the fastboot command, but with Windows 10, it's always telling me it's not a valid command. I'll keep trying it, otherwise, i'll have to "resurrect" my old Windows XP computer.
Also, I noticed now that, while trying to install the fastboot, as per some files that I could download, but no file has been copied into my computer, not even if I run it as admin.
fixed. but no RECOVERY mode options....
Hi Guys,
Thank you very much for the help, I have finally recovered the phone and running android 6.0 MRA58N but it is not rooted. Now if you don't mind could you teach me how to root because i have checked lots of videos and tuts but none worked for me...
IMPORTANT:
when i am in recovery mode why cannot I access options even when i press volume up + power button and release them at the same time...????
Thanks in advance.
Just flash a custom recovery via fastboot. Just make sure your bootloader is unlocked. Can't link though.
