[Q] SGS won't boot up - Android Q&A, Help & Troubleshooting

Hi everyone!
I had my SGS rooted and flashed with MIUI rom.
I wanted to change the rom so I entered the recovery mode (cwm) and wiped all data.
In addition, I entered the "mounts and storage" option and then accidentally clicked on ALL the format options which were there.. (among them, the system and SD)
Since then, I can't enter the recovery mode anymore, and the phone won't start up.
Download mode is accessible (combo)
Odin (in all its versions) doesn't find the device, and when connected to the PC, it beggins to look for the drivers but can't even recognise the device. The drivers were already installed before though.
I assume that my phone has no kernel, no system, no nothing.. am I right? Is there any solution?
THanks!!

Have you tried re-installing the drivers?

[Q] P7510 (p4wifi) Bootloop - tab doesn't connect to odin

Hi Guys!
I have a problem with my P7510.
My tab is on a bootloop
Stock recovery and download mode work
BUT
Tab is not recognized by PC or Odin
Wiping cache and factory reset don't solve this :crying:
This happened after i installed A1 Kernel on Infamous Rom 4.0.4, looking for USB charging. After installing it, no matter what, the PC wouldn't recognize the tablet (no notifications of any kind. Couldn't even find the tab on device manager. tested it on 3 computers, installing and reinstalling drivers, and the same error kept happening), it just charges it's battery. Tried several Roms and Kernels, but the problem was still there
Trying to find a solution i considered installing a stock firmware from samsung, but without USB recognition from my computer, i couldn't use ODIN3 1.85, but i stumbled upon MOBILE ODIN, so i used it to flash a stock firmware, but after a succesfull flash, the tab went into a bootloop. Tried wiping cache and factory reset,on the STOCK RECOVERY (not CWM) and the tab kept bootlooping :crying:
So, to recover my Tab, i need ODIN, but i can't use ODIN since my PC (and therefore ODIN) doesn't recognize my tablet.
So here's when i ask you ¿What can i do to recover my tablet? ¿Should i send it to a technician?
Thanks in advance
Sebastian
Some aclarations:
-I use odin as administrator on windows 7 32 bit
-i don't have Kies on the background
-I instaled and reinstalled the tab drivers
-I looked for the tablet on device manager. I didn't find it.
-The PC doesn't respond at all when i plug the Tablet (no notifications or sound),
Maybe you can try using ADB while your tab is in the Recovery mode.
I accidentally wiped my /sdcard fs and used this method to push a custom rom in the /data/media fs.
Since your Recovery mode is working, you can try to flash a new rom.
ADB Still works on Stock Recovery? (not CWM or TWRP)

My recovery is the STOCK samsung recovery, not CWM are you sure ADB still works with it?
Thanks for your reply, anyways

LG E460 - Black screen, NO recovery, NO download mode

Hallo,
I have an LG E460, as it was slow yesterday I decided to install the ultraslimrom, so I made the root, unlocked bootloader and installed the custom recovery Philz Touch CWM Advanced.
I rebooted the terminal in recovery mode, did wipe data, cache and Dalvik Cache.
And here I have done the damage, in practice I tried to upload the zip file but told me the recovery can not mount sdcard etc .. (I do not have an external sd, only internal memory), so do not know for what reason absurd I connect the phone to PC and I formatted according to all the phone (fat32)
Result: phone that rightly does not light, no lights, nothing, if connected to the PC is detected as "USB serial device" but I can not do anything about anything.
Help please!!

Serious problem

Hello, XDA-Members,
long story short, I tried to flash CM-13 on my Honor 5X(KIW-L21 B340). Well, that didn't work and the phone always booted into TWRP. So I flashed FlymeOS because I couldn't flash the stock rom anymore(No matter why.).
It worked perfectly, and I were able to use my phone. After restarting my phone it booted back into TWRP, tried to wipe and all that stuff and even re-flashed Flyme OS, but still booted into TWRP. I was so UPSET that I deciced to flash the original RECOVERY.img for my Honor 5X. Well and from there I made it worse.
Windows and Linux don't recognize my phone. Windows just shows an empty E:\ drive. Reinstalled Google USB drivers, reinstalled driver etc. Didn't work. Now, when I start my phone it boots into the honor 5x recovery. I got these options available:
- Reboot system now
- Wipe data/factory reset
- Wipe cache partition
So, well. I can't install a rom anymore. As well when trying to connect my phone to ADB it won't work either. ADB doesn't recognize my phone. I made a big bull****, tbh. Installed HI-Care as well, but it doesn't get recognized either. I can also boot into Huawei eRecovery, connect to my wifi because it says it can download the stock rom. Guess what, it always said failed so I'm not able to do this either.
I'm really stuck. Anybody got an idea? Thanks in advance!

Shut down the phone
plug the phone into your windows PC
hold volume down + power to enter the bootloader
from windows open the command prompt - type fastboot devices hit enter (your phone serial number will display)
type fastboot flash recovery TWRP.img (be sure to use this TWRP and it's named TWRP.img and in the same folder as fastboot)
after the file is flashed successfully hold power + volume up + volume down
after 5 seconds let go of power and continue to hold the volume buttons until TWRP boots
From TWRP you can now copy the CM13.zip and Gapps.zip to your phone and wipe/factory reset - then install them one by one
be sure their are no errors .. if you see errors choose reboot recovery and try the flash again until it succeeds.
first boot of cm13 will take some time, be patient
Thanks,
I recovered my phone. Awesome!

P768 shutting down when trying to enter recovery

So, this is my problem: I was using for months now CM13 and TWRP3.0 by EdwinMoq, but the phone suddenly started to drain battery abnormally, I read CM13 was the cause so I installed TWRP 2.7.1.1 to flash Paranoid Android 4.6 BETA. When I wiped partitions to install PA (using TWRP 2.7.1.1), somehow SD Card files were deleted (I didn't select wipe SD Card at any point so I don't know what happened). Then powered off to copy the flashable *.zip again on the SD Card and when I tried to boot recovery, LG Logo appeared but after few seconds phone shutted down (and this happens everytime).
It is a p768 with unlocked bootloader. I can use fastboot just fine, delete partitions, flash them, but I obviously can't flash a system.img via fastboot (it's too big). And I tried flashing different recovery files (TWRP, CWM) and it's exactly the same. I can boot into "S/W Upgrade Mode" too, but when I try to flash any kdz it gets stuck at 15% saying phone is not connected. I tried using another USB port and making Windows install drivers for the device again with no luck.
Drivers are installed correctly (4.0.4 version) and I see phone in the Modems, Ports and USB controllers sections of Device Manager everytime so I don't know what to do. Fastboot is the only thing that's working and I know /system is missing but I can't flash anything.
My issue is kind of like this one BUT, I can boot into S/W Upgrade.
Nevermind, after some quiet crying over the phone I found that my buttons are screwed. I wasn't pressing VolUp right, tricky button. I feel like a retard.
