Hey every one I'm new to xda and I got my samsung vibrant rooted with the stock system recovery and was working fine but than I decided to do some apps and file transfer from another android phone to it and after that my phone kinda froze on me. So I rebooted the phone and boom nothing happen after the galaxy s animation, its just stuck there then the screen went black out. I rebooted again and this time I went to the sustem recovery mode and try to do the data reset but it couldn't fix it either. I tried to connected to my computer but since the phone wasn't fully booted into the home screen my computer are unable to detect the phone driver. I reconnect the phone and computer together, and this time I got to where it say's "downloading" "do noy turn off target", what is that mean? is it download something or is that I'm suppost to do something to it. Please can someone help me out. I've already download the stock firmwire but couldn't be able to transfer to the mass storage cos the phone couldn't boot beyound the galaxy s animation and eventhough its in the system recovering I still couldn't get it to connect to the phone mass storage. What can I do to fix it?.
You can take the battery out at that screen, but I don't know if it's going to fix your overall issue.
Take sd out. Hook to computer with adapter. Move stock nandroid to sd. Replace sd in phone. Boot into clockwork recovery. Restore nandroid. Reboot.you are now stock with root.
one thing
I know what I did is stupid but at lease I learn my lesson. I would really appreciate if someone could help me out.
help
I tried but its not working cost the phone doesn't read what's on the sd card it read only the mass storage which is the 14g not the 2g memorycard.
The SD card won't be in the phone so of course it won't read from it. It will read from the interbal memory, so do it from there.

Turn off the phone, take out the battery and take out the SD card, try to get your hands on a sd card reader for your card so you can fix what you did without using your phone to mount it. Copy the rom or stock firmware over to the card and use the recovery, wipe data/factory reset and then try to load up the stock firmware. if all else fails do a hard reset:
To hard reset Samsung Vibrant, follow the steps below:
Step 1. Turn your Samsung Vibrant off. If your Samsung Vibrant is frozen, pull the battery out and reinsert it.
Step 2. Hold the Volume Down button.
Step 3. Press and release the Power button.
Step 4. You are now presented with a menu that allows for Fastboot, Recovery, Clear Storage, and Simlock
Select Clear Storage by pressing the Volume Down button, then press and release the Power button.
Step 5. Choose one of these: Volume Up for YES and Volume Down for NO. If you selected YES, all data including third-party applications will be deleted from the Samsung Vibrant.
That is for the default recovery so depending on the recovery you are using try to wipe everything and flash the ROM from the sd card, if you need help PM me or contact me on chat.andirc.net #droideris, or irc.andirc.net #droideris
Best of luck!

Smashed myTouch 4G. How I fix?

after a slight impact with the floor, my phone is in a restart loop before the cyanogen boot screen. the only screen i see is the white "mytouch 4g" screen before it powers off and restarts. i can get into hboot, but the recovery option goes back into the restart loop. starting hboot gives some errors about being unable to locate these files:
PD151diag.zip
PD151diag.nbh
PD151img.zip
PD151img.nbh
i think i may have damaged the storage subsystem for sd + usb. last night i was getting a restart loop when i attached a usb cable to my pc, and i think these files are supposed to be saved on microsd.
any ideas?
Those files aren't located on your phone by default so your good, just download PD15IMG.zip from somewhere. I think it's in the development section. but download it, keep it named PD15IMG.zip and put it on the root of your SD card then boot into hboot it should recognize and ask if you want to update or not (vol up or vol down) choose yes and then wait for it to be done. make sure that you aren't low on battery because if this get's interrupted it will brick your phone. Once it's done just reboot and you should be good but this is the equivalent of a factory restore so you'll lose everything stored on the device (not the SD card)

Help me...i've screwd up my phone...:/

ok...so i was playing with the custom partition tool and ended up screwing up my phone...now the phone doesn't boot...i can't mount data or format it...can't wipe Dalvik's cache...i've tryed fixing this with a stock firmware...it didn't even want to install it...it's like the whole data partition off my phone is unaccesable...please helpp...
We do not know what you did to your phone, please explain it.
1) Did you use the tool that increases your internal storage for apps?
2) What happens if you hold vol+ and vol- and turn on the phone?
3) What happens if you hold vol+ while turning on the phone?
4) What happens if you try to simply boot up the thing?
5) What happens if you follow the instructions Huawei provides for updating the ROM?
You might have damaged the partition table of your internal memory. That should not be that big of a deal - as long as your computer still recognizes the device.
If your computer does not recognize the device, do the following: Download the .iso-image provided here. Burn it onto a CD and start it up, it is a linux-live-cd. There will be only one program, gparted. It will recognize your device.
No my computer recognises the phone...i tried to increase the internal memory...if i hold vol+ and - the phone goes in to bootloader...i cna also access the recovery mod...if i boot the phone...it just says IDEOS and frezzes there..i followed the instructions on huawei and stock rooms...install but at the end they say instalation failed...hope i didn't forget anything

Than all you have to do is go into Recovery, mount the SD Card, copy the customer Rom and install it.
Amm...well i tryed that...and it's the same thing..still get that same IDEOS screen and nothing happens..and what is a customer ROM?
We'll...it's over..my phone died:/...i tryed the gparted...and screwed something up even more...so i'm gonna take it back tommorow..tnx for the help..
If you do not explain what you doing exactly I am afraid I cannot help you. gparted is a tool used to format and partition memory. You cannot screw up anything, it is just a software change. I suggest you tell us what you see when you select the device within gparted (which partitions show up etc.) before returning it.
i see nothing..the phone doesn't even wanna turn on now since i did something with gparted...and gparted doesn't show my device..cos it doesn't read it...it's dead..
If it does not turn on anymore you do need to send it in for repair. Please be careful the next time and if you do want to apply that partition program, do exactly what the instructions say. Besides overclocking this is the only thing you should not experiment with.
Well hopefully you get a new device (or a repaired one) soon!

(SOLVED) I install the custom rom successfully, but the phone only starts in twrp (Moto C Plus)

Hello, I have a problem that I've tried to solve in many ways. I unlocked the bootloader a while ago and installed twrp and a custom rom for my Moto C Plus. Recently I wanted to reset it and I did it through the cell phone settings reset option. It started with twrp and then I ran the rom and everything needed for the memory card to flash. The installation happens normally and without any errors and then I reboot the phone, but it always comes back to twrp.
And I can't use the commands by the buttons, only when I reboot the phone from the bootloader inside twrp (Reboot>Bootloader), and appears written right in the lower left corner "=> FASTBOOT mode. . ." and the rest of the screen is all black.
I already tried to install the original stockrom that I got with the IMEI of my cell phone in the program Rescue and Smart Assistant from Motorola, but whenever I try to install by twrp, it says that the zip file is invalid.
If anyone can help me I would be VERY grateful. I'm desperate for a solution.
-->My brother solved the problem!!! Thanks to him.
He used the rescue tool from the program Rescue and Smart Assistant to install the stock rom back (download link: https://www.motorola.com/us/rescue-and-smart-assistant/p). He said too that this error happens because TWRP "dies" and don't work anymore
Process:
1- Remove the battery from you device
2- Open the program Rescue and Smart Assistant, click in "Rescue" and then "Phone Rescue"
3- Plug the usb cable in your device (The program should recognize your phone)
4- With this, the program will give to you the informations and under this have a buttom to "Rescue". Click it and wait the installation
5- After the installation is finished, put the battery back and the device will turn on automatically, but you have to press and hold the power buttom to turn off and turn on again
6- After turning on again, boom!! Your device has been saved ans will start normally

Recovery from bootloop (and other issues)

Ok, so... this is gonna be quite long to tell, but I need to explain the situation as carefully as possible because the problem I have seems to be very specific and potentially solutionless.
So, a week ago my Samung Galaxy Tab S6 Lite (SM-P610, CSC: ITV, which is the Italian Country Code and it's for unbranded devices, since my model is Wi-Fi only), suddenly started to restart itself and it's been stuck for days in a bootloop (i.e. it's stuck on the logo and if I hard restart it with Volume Down + Power, it gets stuck there again). Yesterday I found out that it's most likely a software problem, so re-installing the Android version should fix everything up... right? Well, I did just that but the device is still stuck on the bootloop.
Here I want to be more detailed: firstly, I'm 100% positive that the problem I have is NOT due to a virus, as I've never done ANYTHING that could potentially lead me to taking a virus (such as downloading apps outisde Google Play, visiting risky sites etc.); secondly, I followed a procedure that was supposed to repair my device without losing data. That's because I've stupidly never made a backup and I can't afford to make a factory reset. The procedure I followed consisted in finding the Android update I needed with Frija, and then downloading everything in the tablet with Odin. Also, I'm 100% positive that I made NO mistakes during the installation procedure. The only step that I did differently is HOW I installed the update: I did it with Download Mode, not with fastboot, because when I go into Recovery Mode and reboot the device into bootloader, the PC doesn't recognize my Tab, even if the PC does recognize that it's connected, as it makes the typical sound of when you plug something in a USB port (I have the USB drivers installed in my PC, I think it doesn't work because I never unlocked bootloader). What I get when I reboot into bootloader is "entering fastboot..." stuck screen and the PC and Odin aren't able to recognize it.
My questions are therefore these:
Is there a way to make a backup of the data of my device if I can't boot it (maybe via Download Mode)?
Is there a way to make fastboot work if I can't boot my device?
Is there some other way to repair my tablet that I can try?
Thank you for any help, this is my last hope to find a solution for my problem.

When your device is stuck on an Android boot loop issue then you can fix it by simply doing a soft reset. Turn off your device and the problem will be resolved.
Here are the steps to follow:
First, switch off your device and take out your battery from the phone.
If your battery is non-removable then turn off the phone for 3 to 5 minutes and again turn it on.
This method works effectively to fix the error of the boot loop issue. But if a soft reset does not work for you to fix Android phones stuck in the boot loop issue then you should follow the next method.
Method 3: Reboot System in Recovery Mode​Rebooting a phone in the Recovery Mode is known for fixing several errors and issues on your Android phone. So, if you are unable to start your phone in normal mode or your Android is stuck in a reboot loop, then restart your phone in Recovery Mode.
Method 4: Remove and Reinsert SD Card​You may also try to remove the SD card to fix the boot loop in Android. According to several user reports, this trick worked for them. So, you should try this.
First, turn off your phone > remove the SD card > turn on your phone normally, and check if your phone is out from the boot loop or not.
If it is still stuck in the boot loop, then go for the other solution.
Method 5: Reboot the Phone in Safe Mode​This problem may also occur due to problematic 3rd party apps. If you have recently installed an app on your phone and then you started facing this issue, then remove it from your device.
Or, if you are not sure which app is responsible, then try rebooting your phone in safe mode. Doing this will disable all the third-party apps on your Android phone and then you can easily find out if this is the reason behind this issue or not.
To do this, you need to follow these steps:
Start rebooting your phone.
When the device logo appears on the screen, long-press the volume-down button at the same time.
Now, your phone will automatically switch to Safe mode.
If your phone is no more getting into the boot loop, then it means one of the third-party apps installed on the device was causing this issue.
Now, find out the problematic app and uninstall it to fix the Android boot loop without losing data.
Method 6: Use Custom Recovery Mode​When you find your Android is stuck on the startup screen due to the boot loop issue, then you must try to restart the phone in the Custom Recovery mode. Here is the guide to do so:
To enter into the Custom Recovery mode press the Power + Volume down buttons simultaneously.
Select the “Advanced” option in the Custom Recovery menu.
Next, choose “Wipe Dalvik Cache”. Choose “Yes” when prompted for confirmation.
Move to the “Mounts and Storage” option and choose “format/cache”. It will clear the cache files completely.
Restart your device.
Method 7: Fix Android Bootloop Error Via CWM Recovery [For Rooted Phone]​Maybe you are not aware of this method but it’s a useful way to fix the boot loop issue on Android after the update. Remember that this method is only for rooted phones. Here CWM means ClockworkMod and if your phone is stuck on the Android boot loop then it must be downloaded and installed on phone. Read me

Thanks for replying but I already tried every method listed here.
At this point it sounds like you need to bring it in to a local repair shop & see if they have a fix.
The solution is to wait on the turned on screen until the battery dies completely. Then put it to charge and after a bit using the reset combo (pwr+volume down) once the circular battery charging indicator with the green border comes. (It's a matter of luck, this keeps happening to my tablet and even the official samsung store can't fix it even though they took money to do the same)
