no recovery - Android Q&A, Help & Troubleshooting

After month of search and trial I had to start this thread.
Device Samsung Tab 4 (mother board ET-86V2G-A23-V1.2, A23 processor, china junk)
Problem: I tried to restart the device into recovery mode out of Clockwork. It never reached recovery just shows the logo SAMSUNg Galaxy ab 7 and that where it ended.
Restart into recovery with power and volume button does not work. I tried all combinations 10 times. The device does not have a hard home button.
Conneting to the PC via USB does not work. First is was not set for USB debaging and the PC does not even react when connected (therefore even drivers are useless).
All the advise I get is start in recovery or connect to adb but none of it works as explained above.
Does anyone has an suggestion how to reach into the bowels of the device without revoery and adb (USB connetcion)?
Thanks

Stuck in a boot loop? Try ADB Portable!

I've seen an increase in people who have gotten themselves stuck in a bootloop or can't seem to get the combo right to get into download or recovery mode.
Assumptions:
You have the proper drivers installed
Samsung Driver
Your phone is recognized by your PC
Instructions:
Power Phone off
Extract this folder to your computer
Run batch file for Download or Recovery Mode (it waits to see your phone)
Plug phone into computer
Power phone on
Phone should be detected and go into the proper mode
Thx Red_81, again. Glad to see u put this here for the i777. Appreciate u sharing this. It should provide some good help for many users. :thumbup:

So much easier than trying to explain how to install the sdk and then what commands to run. The only problem is you need to have working drivers.

My phone is stuck in boot logo. Computer is detecting phone as "SAMSUNG Android ADB Interface" but adb is not recognizing my phone.
Any ideas?

Never mind. I just got it working.
Had to just enter adb command directly. wait-for-device is not working for my phone for some reason.
If you get stuck there again, unplug and plug in the device again.

Thanks i was tinkering with a noria 7" tablet, which hasn't worked right since i got it but for 65 bucks its to be expected, but i used sdk manager to get it to register on my computer as an android adb device and for some reason i tried to turn the wifi on and it crashed and got stuck in a boot loop idk why. like i said hasn't worked right since i bought it. But i did use adb portable like you said to get into recovery mode and it worked great thanks! For other noria users when i figure out how to flash a rom to it i'll start a section here on xda as soon as i figure it out. Thanks again
Any suggestions if ADB doesn't see it?
- Phone was working fine in the morning and at lunch I noticed it was off.
- Try to turn phone back on and it is stuck at the samsung menu like everyone else.
- Soft and hard reset change nothing.
- Neither recovery nor download mode works using every key combo that I've seen suggested.
- Computer detects a device but "USB Device not recognized" and ADB can't see any devices (and I know it is set up correctly as I have the full SDK installed and known to be working).
- Charging still works fine and the battery is now at 100%
- Phone is NOT rooted and has no special apps or any recent changes to change the situation (not even app updates since a few weeks)
I'm not sure what else to do. I will probably let it sit for a few days without a battery, but otherwise I would open it up and see if there is some mechanical/electrical issue like a short or something somewhere. Pretty sure this is a software issue though. Any ideas?

To use ADB you must have USB debugging enabled in settings under Developer Options. If you don't keep this enabled all the time, and it wasn't set when the phone stopped working, then ADB is not an option.
Hopefully, you can get into download mode. For reference, here are the ways I know of, in case you haven't tried something here:
If you can get into download mode, you should flash the stock firmware and then perform a wipe data/factory reset from within stock recovery.
There are several ways to put the phone into download mode. You should try all of them that you can before you give up.
Recovery mode:
With the phone off (and not connected to the computer), and battery installed, hold all three buttons, vol- vol+ pwr continuously until the initial boot screen appears the second time.
Download mode:
1. With the phone off and connected to the computer via USB cable, and battery installed, hold all three buttons, vol- vol+ pwr.
2. With the phone off and battery installed, hold vol- and vol+ (but not pwr) while plugging in the USB cable.
3. With the phone off and battery installed, hold vol- (but not vol+ or pwr) while plugging in the USB cable.
4. Attempt each of the above three options with the battery removed from the phone. The computer will supply the power to the phone.
5. Use Android Debug Bridge (adb) which will only work if USB debugging has been already turned on in Developer Options, since you can't boot into the system to turn it on. With the battery installed and the phone connected to the pc via USB cable, use the command "adb reboot download".
6. Use a USB jig. With the battery installed insert the USB jig into the USB connector of the phone. Some have reported that this method works when no other method would work.

Thanks a ton for the reply. Recovery mode does not work but using your methods I AM able to get it to boot to download mode. If it matters, USB debugging was and should still be enabled.
Now the question is... is there any way to backup the phone from this state or get into a state where I could back it up? I don't really care about my pictures or anything else as those were recently backed up but some app settings would be nice to save (Clash of Clans village without Google+, ugh). I'm going to do more research on the next step myself but if you have any suggestions or information to point me in the right direction I would of course appreciate that as well. Thanks for getting me this far though!

It's pretty difficult to recover information from the data partition when the phone is in a state such as you describe. Maybe the developers and technogeeks can do it. I can't. However, depending on where the game saves it's game data, you may be fine. If the game data is saved to the USB memory (internal sd card) then it will still be there once you flash new firmware. Your pictures should also be fine, since they are on the sdcard.

[Q] Can't Fastboot

Hi,
I have on my tf201 latest official firmware, 4.1.1 build-number: JRO03C.WW_epad-10.4.2.18-20121122.
As Asus doesn't provide any more updates for our device and mine is out of warranty I'm finally ready to move on to some custom roms.
My tablet is Rooted.
Now after a lot of reading I thought it would be wise to do a backup of everything and make my device unbrickable.
I started to follow the instructions on this site : matthill.eu/android/transformer-prime-tf201-jellybean-nvflash
At first I backed everything up with Titanium Backup and then I did a factory reinstall, so I would have a clean tablet to start.
Then I installed the unlocking tool and succesfully unlocked my device.
I restarted my tf201 with holding the volume button down to get the options to enter fastboot.
When I got to the selection menu, I press the volume button a few times to select the USB-icon.
Then I press the volume up button to enter fastboot, but nothing happens. It just freeze.
The only thing I can do is hold the power button until my tablet restarts.
Also, since i'm on JB I never could connect it on my pc anymore. It even doesn't show up as an unknown device.
So when I want to use ADB I have to use ADB Konnect (wireless ADB).

When you press up on the USB icon and it freezes that it normal.. This is fastboot mode.
You now must access it over a PC after installing the naked drivers.. If it is not showing on your PC then either try a different PC or your cable is faulty.
Thanks for the quick reply.
I tried once more to enter fastboot. Same result.
But when I disconnected my usb cable to connect it to an other computer, suddenly I got this message on my tablet:
"Starting Fastboot USB download protocol"
This message didn't show up before.
I plugged the tablet back to my pc, but still no device detection in device manager, even when refreshing (So I can't install naked drivers, as it is not recognized).
My computer is a Windows 8.1 system.
I restarted my tablet again, (after disconnecting it from my pc) and followed the procedure to enter Fastboot again.
I waited for the message "Starting Fastboot ..." and then I connected the cable to my other pc (Windows 7 system)
Same result as on the Windows 8.1 machine, not recognized
You say it could be that my cable is broken. Maybe, but it's a strange coincidence that this happened when switching from ICS to JB.
I know JB for the tf201 is been out a long time, and I updated since I could. So over time, maybe my cable could be broken now. But I'm sure I had this problem (not recognizing) since then, because right after updating I wanted to do some things with ADB and so I found out I had this problem.

(Help) Asus ZenFone 5 bricked, stucks at Asus logo!

Hi everyone, i ask for your help cause i have a common problem but the fixes i found in the forum didn't work for me: my ZenFone 5 stucks at "Asus" logo with a "loading loop" wheel below that.
I know this post may be long but i beg you to read all steps:
1) Phone stucks at logo, but could enter recovery (pressing vol + down), i've updated it via external SD card (official firmware but didn't work) then i've wiped data and did a factory reset. Phone still stucks at logo.
2) Now i can't even enter recovery mode... when pressing vol + down it shows 2 options but whatever i choose the phone reboots. If i press vol + up it says "CSC mode, long press power to restart. Phone still stucks.
3) Now (after some time) the phone's screen doesn't show anything, nor charging icon or notification led when recharging, but strangely the computer recognizes it as a device when connected via USB cable, and the led turns on when i do this.
A friend told me to follow a guide that says to install "Intel Soc USB driver", i did that. After installing, when connecting the device, 2 things should pop up in Device Mangager under "Intel Soc": CloverviewPlus Device and Intel Soc USB Driver... but the second one doesn't show to me
I've also tried Asus flashtool guide... at step 4 it says to click in the box icon and choose the firmware RAW file, so i've downloaded a raw firmware for the ZenFone 5, but oddly it doesn't let me choose any raw file.
Note: the phone is recognized by the pc as "QHSUSB_BULK", so i've tried to update its driver with qualcomm drivers, and now it's recognized as "Qualcom MMC Usb storage device". But i think i've did a wrong thing cause my friend told me i should have choosed some kind of official driver
Thanks in advance for your help

help with twrp/odin

I've been flashing custom roms on android devices for several years, but the Gtab S3 is the first Samsung device I've ever dealt with. On top of that I normally use ubuntu and I'm not familiar with window. I'd be most appreciative for your help with odin:
1) When I first plugged the S3 into a window machine I thought it would complain about lack of usb driver. It does not, to my surprise (it seems unlikely that that laptop would have the drivers already installed but maybe I was wrong); nothing happens on the Window side, and S3 says that it's getting slow charging.
In any case I installed the OEM usb driver in https://www.xda-developers.com/where-to-download-android-usb-drivers/ and then plug in the S3, but again nothing happens.
2) I installed odin 3.12.7 but it does not seem to see my S3 (see the attached screenshot).
3) The OP of this thread says
"put your device in download mode"
How?
I did try to google around but I have not been able to find useful help (e.g. as the screenshot shows my odin does not look like the one in step 6 of www.techbeasts.com/how-to-install-twrp-recovery-using-odin/). I enable USB debuggin mode & OEM unlock.
Many thanks for your generous help.
Maybe I cam help.
First have odin up on your pc with the usb cable plugged into the pc but not the tab.
Then with the tab turned off simultaneously hold the power, vol down, and home buttons. The tab should boot into download mode. Hit vol up to get into download.
Now plug the usb cable into the tab.
You should see odin recognize your device and then be able to flash.
You need the Samsung USB drivers and DOWNLOAD mode.

Question Did I brick my phone?

I seem to have gotten my N200 in a state where it will not power on. No screen display, no vibrations, and unresponsive to volume and power buttons (standalone or combination). It's a DE2118, T-Mobile variant, network locked and not rooted.
Here are the conditions leading up to it:
The phone was plugged in to my PC via USB, (through a USB hub).
My Sim/SD tray was ejected.
I had been using an ADB shell to disable-user some apps and check out some various PM commands.
I did not terminate the ADB shell before powering down from the phone.
Once powered off, I held the volume up+volume down+power buttons to attempt to check out the recovery mode. I've never entered recovery mode before on this device.
The USB cable was still plugged in and I could hear the USB new device sounds on my PC a few times while I did this but didn't think anything of it.
Nothing ever appeared on the screen and pushing any of the buttons seem to provide no response.
Battery usage was at least 80%, if not closer to 90% before this happened.
It almost seems like the device is powered on and running as there feels like there's some very slight warmth on the back panel, near the center just under the camera area but I might just be imagining the warmth.
I'm aware that it needs to be network unlocked before it can be rooted as per other threads and I have not tried any root methods.
I still have my ADB shell dialog up but there really isn't much interesting in it besides a lot of the command help dialog.
What are my options?
Note: I recently installed the Jan 6th android 11 security update maybe a day before.
Edit: For anyone looking at this later, the phone came back after a complete battery drain and partial recharge and I was able to replicate the bricked state performing the same thing, usb debugging on, plugged in to usb hub on pc, shut down phone, then holding all 3 buttons down for a while.
Windows or Linux pc?
Does your device show up in device manager if windows?
If Linux, do you see the device if you run
adb devices or fastboot devices?

I'm using Windows 7 mainly.
It shows up in device manager when I plug in the USB but with error code 28, unknown driver.
In Win7, "adb devices" lists a blank line for devices.
In Linux, "adb devices" lists a blank line for devices.
In Linux, "fastboot devices" has no output at all.
If your phone is showed in device manager you should be able to give him his life back...had the same situation long time ago with my oppo find 7..
Try this, and see if it'll recognize you for MSM download.

Will give it a try. Going to be a few hours to DL the file as I'm on an extremely slow connection atm.
Well, I think that made it worse. Couldn't get the Qualcomm CAB drivers working on Windows 7, but got it through Windows Update. The MSM tool went through the process fully but afterward I unplugged the device and tried to boot, still no response, nothing on screen, no vibration. Now when I plug my device back in to the USB, I have an endless new usb device noise and windows says "Unknown Device". Device manager refreshes constantly while its plugged in. Looking back I should have probably tried ADB first before running the MSM tool.
After almost 24 hours of being unplugged, I tried plugging it in again and it finally had some signs of life with the low battery warning and then TMobile splash screen+vibration+sound after about 5 minutes. Still waiting on it to charge up for now. Probably just needed to be power cycled in the end instead of attempting to flash anything. I sure do miss the days of removable batteries.

In the future, you can power cycle the device by holding all three buttons on the phone for 30 seconds while it isn't plugged into a PC.

I had tried that yesterday to no avail. Was very strange. Everything seems to be working as normal now, though factory reset from running the MSM tool. I'm wondering if I'd be able to duplicate the issue again.
Could not replicate with USB debugging off and plugged directly in to my PC's USB port, but turning on USB debugging and plugging in to my USB hub, shutting down the phone, and then power cycling with all three buttons brought the same bricked state.
Don't know for sure if the USB port matters but while bricked plugging in to the USB hub always gives a USB device error sound. Going directly on PC it connects fine as a new device (as QUSB_BULK without drivers or Qualcomm HS USB QDLoader 9008 with drivers). ADB/Fastboot commands from PC's command line don't seem to do anything.
I did notice the fastboot menu show up on screen for a second when power cycling this time and I don't recall it appearing the first time. I think i may have had "advanced reboot" turned on the first time, while it was off this time.
Powercycling actually reset it this time.
Possible solution
It would seem that you can force MSM to write both a and b slots, which might fix your issue. Might be worth a shot
Note: If this swaps you to the Tmobile software, there's no guarantee you'll have anything but a phone that cannot be bootloader unlocked again. Since unlocked have no unlock token, trying to do so with a phone that isn't technically Tmobile may be an issue.
Just had the same problem. Holding all buttons for 30 seconds worked.
if you bricked it and you have tmobile variant you can restore it weather you have a locked or unlocked bootloader.
you have to get your phone in EDL mode, once in EDL mode you will see the "QUSB_BULK_CID" in device manager. you will then need to install qualcomm drivers (if done manually you will have to endable windows test mode, if you use the qualcomm USB driver installer then it will do it for you and you will be in test mode upon next windows reboot.) Reboot windows in TEST MODE. NOTE: i said WINDOWS TEST MODE... Once in windows test mode the driver should function and look normal in device manager. From there just open the MSM tool for your version of Nord N200 and flash and wait about 3-5 minutes. Reboot the phone and you are back in Oxygen OS.
Tips and extra Files needed below:
for the tmobile NORD N200 MSM tool
Index of /list/Unbrick_Tools/OnePlus_Nord_N200
The installer for the QUALCOM USB drivers can be found here at this website (ONLY use the QUALCOMM drivers from here, do not use any other file as it is for a different phone):
droidwin.com/unbrick-oneplus-7-pro/
once done unbricking and restoring your phone you can then exit windows test mode by running
bcdedit -set TESTSIGNING OFF
at the windows command prompt as ADMINISTRATOR.
