[Q] Can't Boot to Recovery, Kernel Missing?

Hello all. With 9.2.1.17 I rooted using vipermod (http://forum.xda-developers.com/showthread.php?p=21009605) and kept the root with OTArootkeeper. Everything works fine except I no longer seem to have a recovery mode. I have Clockwork mod, which I installed after rooting and it was working fine until the recent eee pad update to 9.2.1.21. Now, if I try to reboot to recovery I get the green android... then he dies.

I have searched the forums and google and while I've found plenty of interesting methods, none of them seem to bypass this issue. CWM will not reboot - the reboot is completely skipped. I used to use an app called Reboot2Recovery and that just gives me that above image.
-That image btw will stick around for a few minutes and then the tablet will reboot itself if left alone.
Some other info: I don't have any mods. I only rooted to be able to use TitaniumBackup. I have tried doing a factory wipe of the tablet but even afterwards, still no recovery possible.
I appreciate any help! I would like to unroot my tablet and just start all over. I have nothing to lose.

Use RecoveryInstaller to install CWM again.
Seems like you lost CWM, what you see now is the stock recovery

Thank you! I feel so stupid that I didn't find that on my own. I tried reinstalling CWM using the adb push and was getting nowhere (I'm not exactly an android guru).
It's working like normal now, but I'm wondering if I unroot now and uninstall CWM will I still be unable to get to the recovery mode? I ask because I am thinking of sending my tablet back to Asus because it won't stop rebooting. I get the feeling that if I can't get the stock recovery to work they won't work on it...

If you flash an official stock rom from asus you'll also have the stock recovery back. But sending it back to asus most likely won't fix your reboot problems as a lot of people reported having them. It seems to be a bug of the ICS firmware.

I'm on rooted 9.2.1.17 and was having sleep of death and reboot issues. Since I flashed ICS kernel 16b I've had no problems. My system has been over 10 days with no reboots. It's worth a try. You can always flash back to ASUS stock from recovery.

Urgent Help!!! qhsusb_dload mode on PC but turn on, on charger

Hello guys, hope someone can help me, i have a HTC one S i bought of street, phone was working fine now all of the sudden when i connect to PC i get qhsusb_dload mode, and wont turn on or anything, no LED, so i figure it was bricked, but now when i connect to charger and Hold Power + volume down it boot into stock ROM fine and i can use while i charger, now if i unplug and connect to PC it turns off and get same on Device Mgr.
Battery seems fine and its fully charged, now as long as i dont shut screen off, it works fine.
Also i managed to boot in Boot-loader (Power + Volume down) and on the top it says
" Tampered"
"Locked"
"Security Warning"
Keep in mind i don not have warranty so im thinking my only solution would be jtag but since its not completely dead i'm wondering if it could be something else since it does turn on, mostly whenever it wants. I have not touch anything on the phone related to root or anything
Any help would be appreciate it i cant afford to buy another phone for now.

SM-G920P - Stuck on TWRP Screen!

[SOLVED]
So first of all, I apologise if another thread has been created. I have looked around and have seen nothing similar to my situation. I would greatly appreciate if anyone could help me out.
I rooted my SM-G920P device and trid to install the TWRP Recovery. I'm currently on 5.1.1.
It didn't work and I ended up with the start-up screen saying:
SAMSUNG GALAXY S6 Powered by Android.
At the top left it says: Recovery is not seandroid enforcing.
I have tried flashing twrp 2.8.7.1 with ODIN and I end up with the following screen.

}
The touch screen does not work so I am unable to swipe.
This is the issue I am having.
If I can get my phone back to normal functionality, I would really appreciate it.
Many thanks in advance.

Hi teekeiwong,
Press and hold "Volume Down" + "Home" + "Power" until phone reboots. When you see boot screen, release power key but keep holding volume down + home until you get to download mode. Release all and press volume up to agree to enter download mode.
Download this on your pc and open up Odin.
Connect your phone and add your downloaded file to the "AP/PDA" button in odin. Make sure ONLY F. Reset Time and Auto-Reboot are checked. If anything else is checked then uncheck it before starting.
Click start and wait for it to finish, might take a while for your phone to boot first time after flashing
AFTER you are back to stock, take a GOOD look over here and you might just get a working root & custom recovery
Hope this helps!
- Renolz

Thanks Renolz.
I've been searching forums all over the place. I'll give it a try when I have a bit more time on my hands.
Thanks again.

Also I have another queestion which I hope you will be able to help me with. On my phone when I go to Settings - About Phone, the model number is SM-G920F. However when I go into Download mode I see that the model number is SM-G920P.
What am I supposed to go with?
Also after flashing the Noble ROM to convert my S6 into an S6 Edge Plus, I lost the baseband. I no longer can gain any signal to make calls nor texts. Would you have any idea how to go about this?
Thanks again

Same Issue...

Bricked my wife's SM-P900? God help, please!

Hi,
A few days ago I tried to update my SM-P900 tablet after 3 or more years without updating. I tried to flash this ROM (https://forum.xda-developers.com/ga...7-1-xsm-p900-unofficial-cyanogenmod-t3524788/), but it didn't boot. I flashed the recommended bootloader and recovery with Odin, but I'was not able to boot. Somehow, neither booted Lineage 13 (https://forum.xda-developers.com/ga...t/rom-cyanogenmod-13-0-android-6-0-1-t3366834) nor Resurrection (https://forum.xda-developers.com/ga...lopment/rom-resurrection-remix-5-8-2-t3563635). The only ROM I managed to get working is CM 12 (https://forum.xda-developers.com/ga...t/rom-cyanogenmod-12-lollipop-5-0-1-t2971945/). I thought that the problem was the bootloader, and someone suggested that I flash a more recent (at least lollypop) bootloader. According to Phone INFO, my bootloader version was P900XXUANI1. I tried again and again to flash the BL_P900XXU0BPA1.tar.md5 file, but, despite Odin showing the PASS! message, Phone INFO kept showing the same bootloader version. After that someone recommended that I flash the most recent stock image, so that I get a recent bootloader, that is what I tried to do.
I downloaded the file Samsung_SM-P900_(P900XXS0BPL2_P900OXE0BOI1_Russia_v5.0.2)_by_ (FirmwareOS.com) from a sammobile kind of site. What I look for is that ...BPL2 version that seems to work for other people. But after flashing it, the tablet doesn't boot and I can't access download mode. The only thing that i get to boot is the stock recovery, but it doesn't have the flash img option nor the reboot in Download mode that TWRP had. The only options I got are "Update from external storage" and "Update from ADB". Either of them don't let me flash a full factory image nor, apparently, another bootloader or custom recovery. When I try to flash it I get "E: footer is wrong \n E: signature verification failed" and if I do it via ADB, the error shows right away after a 0% transfer.

}
EDIT: Other symptoms I found are:
- I can't manage to power off the tablet using just the buttons: it always reboots unless I select the Power off option in the recovery. Also if the tablet is connected by USB to the charger or the computer it always try to boot.
- When the tablet is connected via USB and I try to power it off, the tablet reboots and shows a battery symbol, but is gray and kinda strange.
I'm pretty desperate now. This is my wife's tablet and I tried to update it so that it was more secure. I'm screwed.
Any ideas? Is this fixable?
Thanks in advance.
Regards.

Did you try to download the stock rom which consists of several parts with the samfirm software?
For that you have to check the binary box in SamFirm and to insert device type and region.
Flashing that might work better.

I forgot to update the thread. I managed to fixed the tablet. It turns out the tablet hadn't enought battery to enter download mode and I was messing up with the Vol Up and Vol Down buttons. Really embarrasing. Hahaha. After fully charging the device and pressing down the proper buttons, I managed to enter in Download mode and flash a new image.

Bricked Nexus 5?

HI,
I've attempted to install Ubuntu Touch on my Nexus 5 using the UBPorts installer on Windows 10, all was going well until the installer hung on "preparing system image...".
After rebooting the phone numerous times, the screen remains stuck on black screen with the Google logo in middle and a lock icon at the bottom center and is unresponsive to anything. See screenshot.
Have I bricked the phone irreversibly or can I save it?
Thanks in advance

If you can get into the bootloader, try fastboot flashing the last factory image.

You can follow this guide for the Pixel 2 XL. https://forum.xda-developers.com/t/guide-unlock-flash-root-for-the-pixel-2-xl-taimen.3702418/
Just make sure you use the last Nexus 5 factory image found here and not the Pixel 2 XL factory image... https://developers.google.com/android/images#hammerhead
Follow the "Installing fastboot and adb" and "Flashing factory image (clean flashing a factory image (wipe everything))" sections.
