[Q] Soft bricked RAZR MAXX - Motorola Droid RAZR

[Q] Soft bricked RAZR MAXX - Motorola Droid RAZR

Hi guys
My XT910 was submerged in a river a couple of weeks ago. It did not short circuit, but I think it got soft bricked.
Whenever it boots, it will display AP Fastboot Flash Mode (S).
I can boot to Boot Mode Selection Menu with Power + Vol+ + Vol-, but I cannot scroll or select anything. I usually enter the page so that I can access BMM to Power Off the device or access the internal storage.
I tried to Fastboot an Asia ROM but the process got stuck at Step 2. I had no choice but to unplug USB. From then on, my laptop could never detect my phone again. I am using the latest Motorola Drivers and cable.
Today, I tried what was suggested here:
http://forum.xda-developers.com/showthread.php?t=1738769
but because my phone could not be detected by my laptop, I transferred the Boot_new.img to MicroSD and used BMM to flash new kernel. (I wasn’t sure what I was doing.)
Now, when I boot my phone, AP Fastboot Flash Mode (S), and what I get after Boot Mode Selection Menu is a brief Motorola logo and Invalid Flash Mode (S) (Boot Failure).
As of last check (half hour ago), battery health was at 96%. I cannot power down the device without BMM, or at least I don’t know how to. Can anyone assist me on restoring my phone to a functional state again?
Edit: prior to all this, my phone was on Euro OTA Jelly Bean

[Q] Help regarding rooting please

I have a strange situation with my Razr XT910, let me explain to you guys and please tell me what to do:
1- My Razr was on 2.3.6
2- I rooted it, but I cannot remember which method as I tried many ways and cannot really remember which one succeeded.
3- After rooting I flashed a 4.0.4 AOKP-GSM-J.Y.Daddy rom
4- I have several issues with the rom so I want to install another rom, so I tried Eternity project rom. It didn't work and gives me message "Installation aborted", so I gave up.
5- Decided to go back to stock rom, so downloaded the right SBF and RSD lite.
6- I put the USB debugging on
7- I turned my phone off and go to boot loader mod by holding Volume +/- and power buttons and go to SBF flash, connect the USB cable and hear the notification sound from my laptop. No message received from the PC saying installing device. Receive message from RSD USB connected and one clicked show device it gives everything N/A
8- Uncompressed the SBF and pressed start. Then process FAIL
9- Now, tried to turn the phone on, I have to go to to Fastboot mode and press power long then screen goes off. Then I press volume +/- with power again to go to bootloader mode then choose normal reboot to turn my phone back.
10- Tried the above steps over than 30 times for 2 days. Suddenly I discovered that my phone is unrooted when I tried to install any app requires rooting such as Titanium.
My ICS works fine with some bugs, I still wants to go back.
Can any one help me, I explained everything I'm going through.
Appreciated.

Help :( , XT910 Brick after updating with CM ?

Good day all to you
I have the moto xt910, until this morning it was fine with 4.0.4 .
I downloaded 4.4.2 + gapps for it and prepared for updating. The xt910 is rooted, i backuped anything, i put CWM on it and then i began to boot into recovery mode. I backuped again and then did the steps I was adviced to: Wipe data/factory reset - wipe cache and then wipe dalvik cache.
After that I installed cm11 on it - everything was fine. then i needed to install the gapps stuff. i recognized i did not have it on my external sd-card so i put it the card out of the xt910 and copied that .zip from my pc to the sd-card. I put back the sd-card into the xt910, waited a minute and tried to access on it again to install gapps.... The Bootloader stucked, couldnt do anything at all, it disappeared. only option was "power+volumedown".
After this i just get the "moto logo-dualcore" sign for 10seconds, screen goes black and thats it - nothing happens.
Pressing power button - nothing happens at all. Pressing power+volumedown, the logo appears and screen goes black again, no bootloader or anything else (the screen looks like it is slightly lighted in black but absolutely nothing to do).
When i press power+volumedown and i release power when the screen flickers but still holding volumedown, it appears white font saying this:
"AP Fastboot Flash Mode (S) 0A.74 - eMMC Info: Size 16G - To return to normal mode - first press power key to power down - Device is LOCKED. Status Code: 0 - Battery OK, OK to Program, Connect USB, Data Cable"
I can press power, it goes off, I can press power, logo appears, still stuck in the same again as before . When connecting with usb it tries to install drivers, but it doesnt found anything ( Usb Driver is ok, all others failed to install)
Is the phone dead or can I somehow reset it again or make it work again?
Thanks to everyone and hope for your answers and help

Thanks for your help,
I already tried RSD Lite but it doesnt recognize the phone. How am I gonna do that?
I installed motorola device manager and it shows 4/5 driver ready. The one that wont work is "MTB-USB Driver"
Klicking on Motorola Device Manager it just tries to update but dont find anything, it says "Current Version: N/A"
(I havent seen those drivers before, when the phone worked the drivers were called somewhat else on computer)

Try other usb port.
Turn of the phone,then turn it on,while it´s connected to usb.
If that doesn´t work,deinstall all motorola drivers,restart laptop (computer) and install them again.
And you must press vol- vol+ and power button to get to the AP Fasboot mode.

[Q] How to factory state (no SS, no JBX, etc)?

I have flashed my (now my father's) razr couple months ago and now GPS stopped working. It needs to be repaired.
I kind of know how to remove safestrap but what really annoys me is JBX kernel boot logo which appears whatever I do. I can be using stock rom and have no safestrap (nor other roms) installed but JBX logo still appears. I have never been really using it, just tested it once and since that, it is stil there.
Any idea how to remove it?

You need a PC to do this and just a regular USB/Charging cord that you normally would use to connect it to a computer.
You need to RSD it, It'll erase everything on the Internal, not the SD card so that should be safe.
Here is a link for the RSD program. LINK
Here is a list of different versions of Android you can download for your Razr LINK
And you also will need these drivers here LINK
(skip this step if your stuck in a bootloop)
1. Now what you do is you connect your phone to the computer, I used Media (MTP) mode. Install the Drivers and install RSD lite. and pick your Fastboot file version you want, I did the 4.1.2 so i could root it again with the easy root, but its your preference. Now Unplug your phone and hold power and turn it off.
2. Now press Power and Vol DOWN together. if it doesn't do anything let go of power button but keep the Vol DOWN, It should come up with a menu. Let go of Vol DOWN and tap it until you get to the option that says RSD mode, then press Vol UP.
3. Connect your device to the computer. RSD Lite should show a device on slot 1. Click it then press START. now browse and find the fastboot files the click Decompress and flash.
4. DO NOT TOUCH THE PHONE. DO NOT TOUCH THE PHONE. DO NOT TOUCH THE PHONE. DO NOT TOUCH THE PHONE.... oh yeah, one more thing. DO NOT TOUCH THE PHONE!
5. After its done, VIOLA. Stock phone. Re-Root. Reinstall SafeStrap. golden!

[Q] Need help with my Droid Razr. (Bricked)

Hey guys,
I had purchased this phone awhile back in 2012 and The model is: XT912. I had rooted it and installed a Custom Rom (Black Widow). The reason why I stopped using it was because I had a cracked screen so I upgraded to a different phone but having alot of issues with my new phone. So I decided to replace my screen for my Droid Razr, but its been awhile since i've used it and been experiencing issues of my phone not booting up and looked online for multiple solutions but no luck.
Issues are:
- Phone needs a USB Wall Charger to be able to be turned on, battery is charged fully but when I unplug my USB Charger, my phone turns off. When I try to attempt to do a fastboot session, I connect my Stock Motorola USB Cable to my PC and on my phone, it shows a white light. But when plugged in to a wall charger, my phone boots up but doesn't boot anywhere besides the motorola logo.
- My phone boots up, shows the motorola logo and goes straight to battery charge and it shows 0% then 5% then 100% sits there for about 3 minutes and then reboots.
- When trying to go into recovery, it stays on the motorola and i've left it there for 24 hours abd no luck.
I've tried multiple things, but its been very aggravating since I've been trying to look up solutions for the past week but still had no luck.
Please help =(

The white light means that your battery is empty,try this:
Booting from AP fastboot to charging mode
If the Device will only boot to AP Fastboot and it says Battery Low
Connect the phone/Device ato a Wall Charger (not PC)
-In AP Fastboot Mode hold Volume down& power buttons at the same time for +10 seconds
- When screen goes black...release power button
-Then IMMEDIATELY press and hold Vol - and Vol+ to boot to Boot Menu.
- In Boot Menu scroll down with volume down to BP Tools, press volume up to select
- Device should boot to Charging Mode with battery icon
- Once battery is charged, try flashing in AP Fastboot again
This will only work if battery charging Firmware is still present and not corrupted
If Motorola Device will not boot to Charging Mode, a Fastboot cable will be needed.
You can buy it or you can make one by yourself,look at the picture.
If you can boot to AP Fastboot mode use this utility to flash stock rom,here http://forum.xda-developers.com/droid-razr/development/droid-razr-utility-xt913-jellybean-t2861798
If nothing works maybe your battery needs replacement...

I've tried the troubleshooting steps mentioned above but no luck.
What I remember is that, back in the day when I installed the ROM, I wiped everything, incl. the Recovery partition and I believe android version it was on was ICS. When I installed Black Widow, everytime i would reboot it, i had to turn it on a certain way, sort of like safe mode. I've tried it though but no luck
Also, everytime I do plug in a charger, It does show a charge of 100% but once I unplug the USB, it turns off and the only way to turn it back on is plugging the USB back in.
I've also created the cable you've mentioned, but it still shows a white light when plugged into a PC. I've already replaced the battery and the battery is brand new. Just replaced it yesterday.
Any other suggestions? Is there a way to fastboot it so i can install a stock rom with the OTA?
Thanks.

You can't charge the phone with the fastboot cable,it is for flashing the stock rom with RSD Lite when your battery is low.
Here is everything you need

Download Motorola drivers,RSD Lite,appropriate sbf file for your region and flash it.
Oh,use Windows 7,not Windows 8

Use this utility because you have XT912

Ok, So I was able to get to the Boot Logo usuing HW Diag. and Boot AP and my screen would show safe mode activated, then it would boot up a logo and I believe its cyanogen mod. It has a Blue Droid with a ring circling around it, but then it restarts. Maybe if i'm able to boot it into safe mode from the beginning, i could start it up.

Tab S6 stuck in bootloop, can't get to recovery mode

My Tab S6 tried to auto-install an update yesterday (it is rarely connected to Wifi/internet). It then rebooted. Since then, it's been stuck in a boot loop.
It will display the "Samsung Galaxy Tab S6 | Secured By Knox" logo screen for a few seconds, then switch to the blue "Installing System Update" screen (with the android logo). Installing System Update gets to 28% and stops. Then the rotating icon on the android freezes. Then the device reboots and starts all over again.
Edit: the tablet is 100% stock. It's not been rooted or had any custom ROMs loaded.
I have tried getting to recovery mode, by holding power+volup while it boots. This doesn't seem to change the behavior at all. Any advice is much appreciated.

I can't actually shut it down. If I start holding power+voldown right after it boots, the tablet does reboot before getting stuck at 28%. But it reboots--it doesn't power off.
I tried download mode and that actually seemed to work! Specifically, I left the tablet overnight in the reboot loop until the battery drained. Just now, I held down volup+voldown and plugged it into my laptop. I got the green "Warning/Custom OS" screen and then pressed volup to continue. The tablet rebooted pretty quickly after that (I'm guessing due to low battery) so I didn't get a good look at the download mode options.
Once I'm in download mode, can I factory reset the tablet? I don't need to preserve any data/apps/settings.

You cannot reset the tablet from Download mode afaik- You need to enter Recovery Mode to do that.
You can however, flash stock from Download mode using Odin (3.13.3 is best). If you're not confident with doing that, your best option is Factory Reset in Recovery Mode. Hold Volume Up and Power when the Tablet is booting, let go when you see the Samsung logo. The timing can be tricky, but you should be able to do it. Also, you can force a reboot with Volume Down and Power.
Alternatively, if factory reset doesn't work, since you're completely stock, you will still be covered under warrenty.

Thanks for the suggestion. I have tried this many many times. I've tried letting go of the buttons at different times. I've tried holding volup while letting go of power. I've tried this a ton of different ways, and no matter what, the tablet always shows the "Installing system update" screen. Some googling has led me to believe that sometimes, when performing a factory reset, the "Installing system update" screen shows up right before the normal recovery screen. Is it possible that the tablet is trying to get to recovery mode, but can't get past this first step?

Honestly, I don't know - I'm not an expert but I guess it's possible that the update failed and corrupted both System and Recovery.
You'll be covered under warrenty, so maybe just return the Tablet from where you purchased or direct to Samsung, could take a while given the current situation though I guess. If you have a PC, then I think the best option would be to just flash stock yourself, since that's probably all Samsung will do. Even if that doesn't work you'd still be covered under warrenty, as far as I'm aware attempting to flash stock doesn't trip Knox.

Here is solution to unbrick your device!!!

Despair not...I have just come from resolving this exact situation not 30 minutes ago. I'd been trying to flash (using Odin as I decided to stay on Stock and not root this device, for a change) the latest OneUI2.1 releases for my device (SM-T865 - LTE version) and boom in the middle of the Odin update, the flash just failed...I then couldn't reboot and get into neither Recovery, nor Download Mode because it appears my bootloader and recovery both got corrupted.
Here's what you need....
1. Odin app for PC (am on Windows)
2. Your device's Stock firmware (sammobile firmware archive)
3. You will need someone to help you boot the device directly into Download mode (and this is the tricky part because for most of us we are used to get into Bootloader by using the key combination (from Powered Off device) Vol+ and Power On at the same time to get into stock recovery and then scrolling down to option 2 in this menu, "Reboot to Bootloader". Well now you are going to boot directly into Bootloader mode. Here's how you do it...
4. Get your friend to line up the USB-C cable into the port of the device, but DO NOT press it in...yet
5. Press Power off and Vol- buttons at the same time to turn off the device
6. And now you have to to be super fast: if device starts to turn on on its own, YOU press and hold Vol+ and Vol- both at the same time while YOUR FRIEND pushes the USB cable fully into the port - you should now have booted directly into Download mode. (if not repeat this, and remember to be super fast and sync with your friend pushing in the USB cable)...
7. When you get into Download mode, then you are home and dry...
8. Select ONLY the Bootloader file (BL...XX...) in Odin, make sure only "reset time" and "reboot" are ticked, and flash
9. When device reboots, press Vol+ and Power combo to get back into Bootloader mode again...but I think device will reboot into Download mode on its own
10. Now select all the files from your Stock file into the various tabs (BL, CP, CSC, AP...) do not select HOME_CSC as we want to flush this device clean...
11. Flash, and voila...success - you will have lost all your data but rather that than losing the device...
12. Feedback here and let us know if this works? For reference for others in the future...

FYI, I got in this situation, and the previous post did work for me, just takes good timing! Thanks!!!!

Same issue today for me. My tablet showed different screen with green and red text, it allowed me to delete app data, then booted into safe mode, then i had to do factory reset and now i am screwed, as it is refusing to restore any apps and their settings. I will try to flash it back to Android 9, maybe then it will do the restore. I forgot to do any manual backup to SD or so.
Edit: the device upgraded to 10, but reset itself after about 10 minutes of use.
Edit2: i found what caused it. It is caused by Nova Launcher, if i try to set wallpaper.

Just found a news article that there is a RGB/sRGB problem with wallpapers. It might be the problem i had.
I am adding a screenshot of the result.

Yeah, I had that kind of reboot loop from a wallpaper that I downloaded

I can get into download mode. But it kicks me out within a few seconds. Any help please

I have the same problem with a Tab S6 Lite, it is in bootloop and does not let me enter the recovery mode, I can go into download mode and I flashed the latest original firmware Android11, Android10 etc., . I tried them all but always goes in bootloop, and also the bootloop occurs only if I connect the usb cable to the PC, without any sign of life. Do I still have hopes or have I compromised the motherboard?
The reason for all this is because I had followed a guide to give root permissions with magisk, I did everything right, only that the guide was with Android10, while I had Android11 and I was deceived by the fact that in the title of the guide there was written "guide 2021"
, so I did not check the compatibility of operating systems, I was a fool, I know, I hope so much that I did nothing irretrievable, it's my son's tablet!

Did you use HOME CSC or the non HOME CSC when flashing?

Try to install a castom rooted rom which has pre installed also Twrp.

Download the android 11 last rooted rom from there. You install it with odin as as a normal original rom.
Disable in odin auto reboot. After rom install, restart manually and press the correct buttons immediately to boot in Twrp and not to system. Format (not wipe) data from there and reboot to system. If you are lucky it will work..
(I hope you unlocked bootloader before try to root. If you haven't unlocked bootloader this won't work also).

Here is solution to unbrick your device!!!
Despair not...I have just come from resolving this exact situation not 30 minutes ago. I'd been trying to flash (using Odin as I decided to stay on Stock and not root this device, for a change) the latest OneUI2.1 releases for my device (SM-T865 - LTE version) and boom in the middle of the Odin update, the flash just failed...I then couldn't reboot and get into neither Recovery, nor Download Mode because it appears my bootloader and recovery both got corrupted.
Here's what you need....
1. Odin app for PC (am on Windows)
2. Your device's Stock firmware (sammobile firmware archive)
3. You will need someone to help you boot the device directly into Download mode (and this is the tricky part because for most of us we are used to get into Bootloader by using the key combination (from Powered Off device) Vol+ and Power On at the same time to get into stock recovery and then scrolling down to option 2 in this menu, "Reboot to Bootloader". Well now you are going to boot directly into Bootloader mode. Here's how you do it...
4. Get your friend to line up the USB-C cable into the port of the device, but DO NOT press it in...yet
5. Press Power off and Vol- buttons at the same time to turn off the device
6. And now you have to to be super fast: if device starts to turn on on its own, YOU press and hold Vol+ and Vol- both at the same time while YOUR FRIEND pushes the USB cable fully into the port - you should now have booted directly into Download mode. (if not repeat this, and remember to be super fast and sync with your friend pushing in the USB cable)...
7. When you get into Download mode, then you are home and dry...
8. Select ONLY the Bootloader file (BL...XX...) in Odin, make sure only "reset time" and "reboot" are ticked, and flash
9. When device reboots, press Vol+ and Power combo to get back into Bootloader mode again...but I think device will reboot into Download mode on its own
10. Now select all the files from your Stock file into the various tabs (BL, CP, CSC, AP...) do not select HOME_CSC as we want to flush this device clean...
11. Flash, and voila...success - you will have lost all your data but rather that than losing the device...

Why flashing only the bootloader first? At the moment I'm trying to recover my s20 fe from a bootloop without losing my data

Wiping cache partition in Recovery and reflashing the firmware are basically your only 2 options

Flash in odin the same rom you had. There are 2 csc files in rom, which you use 1 in odin one. Try use the "home csc". Home csc keep KEEPS your data. If you're lucky it may work. (It would work in keeping your data 100% if your rom was ok. Because it isn't you have some changes to work.).
You must try with same rom or newer.
CSC – If you flash the CSC file, it’ll perform a factory reset of your Galaxy device and wipe all data while installing a new firmware to bring your device to the same state as it was when you purchased it. Go with CSC if you want a clean installation.
HOME_CSC – On the other hand, if you want to keep your Samsung phone’s data and settings even flashing the stock firmware, you can select the HOME_CSC file.
