[Q] Nexus Root Toolkit + stock firmware/unroot failed - General Questions and Answers

Nexus 4, 8gb.
I was on rooted 4.2.2, been wanting to un-root it forever but dreaded the idea of it failing. Well, It did fail. I was unrooting it via nexus root toolkit, using drivers adb, and hit flasth stock + unroot, selected the most recent: 4.4.3 build KTU84L
MSDOS prompt got to "sending 'system' (731040 KB)... And it sat here for about 2 hours, after that I pushed some buttons, trying to see if it was responsive any and then unpluged it. At that point it said FAILED, data transfer failur, too many links.. and the script ended.
On the android boot loader screen it said.. "downloading" this entire time, with no update. -- It appeared to be frozen.
So now I have access to the Google loading screen and if I press volume keys and power I can get into the: bootloader, green android laying down.
Mentions:
in red text- Fastboot Mode
mako, mako 8gb, hw vers. rev_11, bootloader version - MAK0Z30d, baseband vers., carrier info none, serian number, SIGNING - production
SECURE BOOT - enabled, Lock State - unlocked.
Pushing down volume, I can access restart bootloader, recovery mode, and power off. and then the Start pic.
No idea what to do now that I have no drivers to load the device for WugFresh Nexus Root toolkit v1.8.3
Also, clicking *Restart bootloader apears to just reload that same screen, and Recovery mode loads an android laying down with red ! triangle. The green start just loads the google logo again.

the fix
for those with a similar issue, here was my fix:

It was stupid simple. I also used the factory usb cable, and plugged from behind the computer.

[Q] [=]Bricked[=] TF700 from ics factory reset

unlocked & was rooted with ICS .30.
I was doing A factory reset, from the tablet options to wipe all games & apps, forgot & wanted to use TWRP. so stopped it from rebooting once I hit the button in ICS to factory reset, bad mistake as, now if I try to use micro sd recovery or APX, but dont have a timer count down, just frozen at this screen.
When the issue first picture with the ASUS logo in the top right corner says::
The Device is Unlocked.
When you try to go to recovery mod it produces here
Android cardhu-user bootloader <2.10. e> released by "US_epad-9.4.5.30-20120907" A03
Checking for android ota recovery
Booting recovery kernel amage
* and everything is stuck here without even a timer, no way to get the usb option even. tried apx shows drivers in windows but dont show a device once you type adb devices. seems to be locked up once it boots now, tried to drain battery & see if it would unlock, nope. tried reset, hard reset, not sure if there is any option to unfreeze, looked around forums & tried many things, but odd it the wipe button is hit in os & stopped even before a reboot, it already wiped some stuff. thought it started after reboot. turned off right when I click the button, was bad mistake of mine.
downloaded JB from asus, unzipped & renamed. but freezes at asus logo without a timer option, or APX wont respond even tho I hear the usb chime & drivers show in windows, ASUS_Android_USB_Drivers were installed, to try fastboot, no device shown tho.
1. Decompress downloaded .zip file (it will be another .zip)
2. Rename it to EP201_768_SDUPDATE.zip
3. Format FAT32 the MicroSD card that you will be using for the update process
4. Copy the file to (the root directory of) your MicroSD
5. Insert it into the tablet
6. Shutdown (power off) the tablet
7. Power it on by pressing and holding VOLUME DOWN and POWER buttons simultaneously
8. When you see white text in the top left corner of the screen, release the buttons ^^ and press VOLUME UP button until you see Android logo and process bar
Let me know if there are other was to unfreeze or is this a $300 mistake to have asus repair as its a software brick.

[Q] Help with Phone Stuck Booting

I'm usually pretty good at following instructions but I have a problem. I am rooted with TWRP, stock kernel. I successfully applied the 4.4.1 update and used the phone for awhile no probs. Tried re-applying the 4 way reboot menu mod that I'd used successfully on 4.4.0. TWRP says flash was successful. I rebooted and am stuck at the spinning google colored circles. I cant get into recovery mode by holding the volume up/down and power buttons. The phone vibrates briefly when I hold all three but the logo keeps spinning. Pressing power button only does the same. Tried connecting to PC but mac says can't read device and to reboot it. ?help?
Update - Got her to reboot with volume down/pwer, into TWRP, and restored from backup, Back up and running...

bricked, can't get to bootloader or recovery, adb doesn't see phone either

Hello, I just unlocked bootloader, flashed custom recovery (clockwork 6.0.4.8), and gained root on my HTC One S. I then attempted to install a custom ROM, (cyanogen 12.1).
After installing and telling Clockwordmod to reboot, I believe I am in a boot loop. The white HTC screen pops up and then goes to black and stays there. When I plug my phone into my computer, I get the connection and chime, and a new device appears in Device Manager called "HTC MTP Device." When I am in fastboot mode, my phone is shown as "Android ADB Interface" in device manager, so this is different. This leads me to believe that my phone is not dead or off, it is on with a blank screen. I do not believe my computer will recognize a device that is not powered on.
I have HTC Sync Manager and I have the option for it to automatically pop up when a device is connected. It pops up, but with an error saying HTC Sync Manager could not connect to your phone.
I am able to hard-reset the phone, by holding down the Power button for several seconds. However, this just repeats the process (White HTC logo screen, then black screen). I am not able to enter bootloader or recovery by holding down Volume and Power. I have tried Volume Up + Power, Volume Down + Power, and Volume Up + Volume Down + Power.
Also adb no longer recognizes my device, so I can not interact with the phone that way either.
Currently, my only idea is to allow my phone to die so I can try booting it into recovery from power off. But if there are any other ideas that would be great.
Right before I rebooted, after installing the ROMs, I got a message saying something like "Root possibly lost, do you want to fix root." I said yes, could this be part of the issue?
I am on Windows 10.

Just in case anyone stumbles on this. You can boot into the bootloader by Holding down the Power Button for several seconds, the soft buttons will blink, indicated ensuing reboot, when they stop blinking, hold Volume Down until you get to the bootloader menu. The phone does not need to be powered off for this. From there, adb/fastboot will recognize your phone, and you can factory reset if needed.
However, I figured out my problem. On older HTC models, including the HTC One S, you have to manually flash the boot.img file that is included in the zip for your ROM.
But now I've made it to the cyanogenmod boot screen and am stuck there. sigh. i've been at this literally all day.
In the end, I just flash a different rom, specially Candy5 as found here: http://forum.xda-developers.com/htc-one-s/development/rom-t2964931 and it worked.
It's possible I accidentally flashed a rom that was incompatible with my device, not sure.
EDIT: I also switched from CWM to TWRP. Not sure if that helped.

I have broken volume down button, what can i do? face the same problem
What does it mean by manually flash boot.img? After flashing a custom rom, do not reboot first but flash the boot.img via twrp which can be found in zip for the rom?

Unbricking HTC U12+

Hey guys - I hope you're doing well.
I recently got an HTC U12+, but wanted to try using a custom ROM due to all of the bloatware . Unfortunately I think I've ended up bricking my device. Here are some things I've since tried:
- Restoring to the backup I made beforehand in TWRP - restore works without any errors, but then just hangs at the boot screen
- Method 1 from this thread (https://forum.xda-developers.com/u12-plus/how-to/collection-htcu-u12-ruu-firmware-t3794664) - TWRP always says the zip files are corrupted for some reason
- Method 3 from that same thread - this actually worked before, but I tried installing a custom ROM again, somehow messed up again, and now this method no longer works as it just hangs at the "HTC" boot screen for eternity
- Both methods in this thread (https://www.theandroidsoul.com/how-to-install-htc-firmware-ruu-and-zip/) - the first one leads to a "failed remote 99 ru unknown fail terrible mishap" error, and for some reason my PC doesn't see my phone when I try the second despite being able to see it in file manager
- Probably many other methods that I've now forgotten
I know this is a whole lot of information, but I'm in desperate need of some help. I typically like to troubleshoot things myself, but I've been trying to fix this for quite some time now and could definitely use another set of (much more experienced) eyes. I greatly appreciate any help you guys can provide.
Thanks.
Flash RUU with SD card method
Download RUU from here(important:check your CID): https://docs.google.com/spreadsheets/d/1wIRrVQawd5rD-t9VKPQ-SdRK20RcJVZhwD7lhmPIK8w/edit#gid=0
1. rename RUU to 2Q55IMG.zip
2. copy zip in the root of your sd card. - external card / not internal - it will not work
3. reboot to download mode,
4. your device will pick up the zip file and flash it.
5.follow on screen instructions and enjoy your RUU(this method erase all your data)
I'm having an issue with my u12+ where it just continually reboots to a message saying "The boot loader is unlocked and the software integrity cannot be guaranteed. Any data stored on the device maybe available to attackers, do not store sensitive data on this device" and then it shows the white HTC logo that says Powered by Android down the bottom of the screen, it stays like that for about 5 minutes and then reboots and does the same thing over again.
Holding the power down button does nothing, it will not turn off the phone. Holding power and volume down does nothing either. The phone just does this every 6 minutes and reboots and cycle and that's it.
I've tried putting the file 2Q55IMG_IMAGINE_DUGL_O80_SENSE10GP_hTC_Asia_TW_1.53.709.1_Radio_sdm845-000201b-1807311356_release_531499_signed_2_4.zip (renamed to 2Q55IMG.zip) on the root of a 8gb Fat32 formatted SD card, but I just can't get into recovery or download mode.
I've tried holding down all 3 side buttons for minutes, or just the power button, or combination of buttons, they all do nothing to the phone. (it's as tho they are disabled, but sometimes holding a combination of the 3 will make the phone vibrate a little bit, but in no particular time or order)
When the phone is in either state (locked bootloader message or white HTC logo) my Windows 10 PC sees the phone plugged in as a "USB Input Device", not an Android Phone or Android Device. So using ADB or Fastboot commands do not work to it. I've tried to force the driver to the HTC driver but that does not work.
I also tried using the RUU_IMAGINE_UHL_O80_SENSE10GP_NA_Gen_Unlock_1.30.617.2.exe file, but once again it doesn't detect my phone.
Any help would be kindly appreciated.
Cheers!
EDIT: So I was finally able to get into download mode by waiting until the phone done its 6 minute reboot and then holding power down until it vibrated once, then held volume up until it vibrated again, then let go of the power button, I was then able to choose recovery, download etc.
So I managed to get the file 2Q55IMG.zip to install, it said it installed 100% okay. The phone rebooted and now I'm stuck again just at the white HTC logo and Power by Android down the bottom of the screen.
This time the phone is not automatically rebooting itself and no key combinations will make it reboot. I've tried holding them all in certain combinations for periods of time, the phone will not reboot or turn off.
EDIT 2: So maybe I didn't wait long enough after installing the 2Q55IMG.zip file, I finally got the phone to reboot and now I've got a working phone again. happy days :laugh:

with the phone off, turn it on,when you feel first vibration
quick release power key and keep push volume down.
Smartphone should boot in bootloader mode.
can you get into this mode with this guide?

Cheer mates, issue sorted. I just updated my comment in my post.
Not sure if I'm game enough again now to try and put LeeDrOiD and Magisk on it.

Is there a way to unbrick my phone without a backup?

I was trying to flash an unofficial image of Lineage and definitely messed something up - the phone is stuck at the "Samsung Galaxy A51" logo and won't boot. The image was lineage 17.1, so I'm suspecting that it was a change in bootloader code. I was previously running Android 11 (R) with Magisk and I think the image is using Android 10. I had a backup, but sadly forgot to copy it over from the sdcard as it was a Titanium backup. So, is there a way to revert this? I also heard about Samsung's Smart Switch, but I don't think it can do anything if I can only boot to TWRP.
Restore and lock bootloader
Reinstall stock ROM
Install last firmware
I have a bricked, Galaxy A51, One UI Version is 4.1, Android version is 12, Product Name – SM-A515F.
Prior to bricking, In download mode, OEM LOCK – OFF (U), FRP LOCK – OFF, KG STATE – Checking Current Binary – Samsung Official
Using Odin version Odin3-v3.14.1; I have ran through the installation process of the TWRP recovery procedure and received a pass in Odin that all the TWRP recoveries below I have tried have installed at each time so have in essence Installed.
(Twrp+vbmeta_A11.tar, TWRP-11-3.6.0-a51-20220210-1636.tar, TWRP-11-3.6.1-a51-20220228-2050.tar, TWRP-11-3.6.1-a51-20220321-1406-hotfix.tar, TWRP-11-3.6.2-a51-20220602-0515.tar, twrp-a51-3.5.0_10-1_ianmacd.tar)
Post TWRP installation, if I leave the cable plugged into the phone after the pass in Odin. On pressing the correct sequence of power and up/down volume buttons it does not boot into recovery it just shows a recharge sign on the phones screen and stays there, nothing else happens after like fifteen minutes.
If I unplug the cable in the phone from the laptop post TWRP installation and on pressing the correct sequence of power and up/down volume buttons. Like now I am stuck in a boot loop session, have been for twelve hours now. From the Samsung Logo warning that I have unofficial recovery software installed on the phone to a message that the phones boot loader has been unlocked and the world will fall in. Then the phone switches itself off for one second and the boot loop returns.
The phone does switch itself off for one second until then it switches itself back on and continues this frustrating boot loop session, actually as I write the battery has just failed and the phone is now power dead.
When the phone switches itself off for one second, I can press both +/- volume buttons and connect to the laptop to open the phone up in its download mode; it still states in download mode that the phone is OEM LOCK – OFF (U), FRP LOCK – OFF, KG STATE – Checking Current Binary – Samsung Official
The TWRP recoveries I have installed are,
Twrp+vbmeta_A11.tar, TWRP-11-3.6.0-a51-20220210-1636.tar, TWRP-11-3.6.1-a51-20220228-2050.tar, TWRP-11-3.6.1-a51-20220321-1406-hotfix.tar, TWRP-11-3.6.2-a51-20220602-0515.tar, twrp-a51-3.5.0_10-1_ianmacd.tar.
They all installed fine with a pass in Odin, but I was unable to open the phone up in recovery by following the correct sequence of power and up/down volume buttons.
Is the phone bricked for good?
If it is will I need to install the official stock ROM. I have no idea which stock Rom to download and install. If this is the case could someone be kind enough to post me a link to where I can down load the correct stock ROM to down load and install via Odin.
Thanks for reading and any help received.
Here’s an update,
I have now reverted back to Stock Rom and I find it impossible to boot into Stock Recoveries.
I have owned this phone over eighteen months and have never before tried to boot into recoveries.
I have tried every method available online, power and volume up button, power and volume down button, power and volume up button while ear phones are plugged in the same with a USB cable plugged in.
But I can still boot into download mode though.
So this might be the reason why I could not root and install TWRP as the phone itself will not boot into recovery. What to do, I have no idea.
When in down load mode.
OEM LOCK – OFF (U), FRP LOCK – OFF, KG STATE – PRENORMAL Current Binary – Samsung Official
So now I have reverted back to KG STATE – PRENORMAL, and the phone is showing no OEM unlock in developer options.
But on boot the phone is still warning me that the boot loader has been unlocked.
I downloaded stock ROM, and extracted these files.
AP_A5 BL_A515FXXU5FVE2_CL23686045_QB51779782_REV00_user_low_ship.tar.md5
BL_A515FXXU5FVE2_CL23686045_QB51779782_REV00_user_low_ship.tar.md5
CP_A515FXXU5FVD1_CP21942801_CL23686045_QB50597459_REV00_user_low_ship.tar.md5
CSC_OJM_A515FOJM5FVE1_CL23686045_QB51677768_REV00_user_low_ship.tar.md5
They all installed fine in Odin and I received a pass. The phone booted and is working fine.
But I cannot boot into stock recovery.
My only perquisites I have not tried are I have not yet gone through the sequence to get OEM unlock showing in developer options. I am also not connected to any networks and have no sim card in the phone.
So anyone not able to root and install TWRP, maybe your phone itself will not boot into recovery in stock ROM.
Any suggestions would be most appreciated.
