Last year(late 2010, maybe mid November), I rooted my phone and flashed recovery with no problem s at all. Some time after that I added Apps2SD and that went smoothly with no problems for about a week. I purchased an 8 GB SD Card for more storage room and after I partitioned it and switched the cards my phone started acting up so i rebooted it. After that I was stuck in a boot loop, so i tried to flash it back to stock but it wouldn't take to it no matter how I tried, whether it be through recovery or SW Update. So then I tried Odin Multi loader(cant remember which version but at the time I made sure it was the one meant for the Intercept) after I flashed it with the Stock through Odin, the phone bricked. Now it will not turn on in any way(recovery or other) the only thing it does do is vibrate when I plug it in to a computer, and it will occasionally show battery life through the touch screen and keyboard buttons by lighting them, but as soon as the it is unplugged it is a brick. I see the little bit of functionality as a little bit of to be able to fix this phone whether through ADB or another function but I desperately need help with this. Can someone please help me fix this phone?
note: I currently have a Samsung Transform as my main phone so if the Intercept can't be helped then it's not that big of a problem.
I have the same problem! Please help!
When you root a phone you put the rom, and recovery onto the sd card. changing sd cards disrupts this process. Put the old sd card in and tell me what happens.
The phone doesnt come on at all
see if you can get it into download mode with the battery out.
Pull battery
connect to computer with usb
vol down + camera + end
If you get into download mode this way flash the stock.tar using SWUpdater.
Nope, it doesnt work, thx though
Ok I've got the same problem with my intercept as well, So i just like to add (maybe its just me) that when i plug my phone to the computer the phone shows that its still functions right (without the screen on), I'm able to make calls, and receive them as well (with the touch of the answer button) but just the screen doesn't turn on, AT ALL!, so KJON i don't know if your having the same problem as me but I'm just a noob and i wouldn't know what to do. But there's some ammo if you need it.
I HAVE THE SAME PROBLEM! i dont even know where /sdcard/sdx/zip/ is!
My phone is also a samsung transform and not and intercept and whenever i press vol down+ Power, only the function buttons at the bottoms light up but not the screen
i am a noob.
help?
noooooob here...i didnt wanna start another thread since i have this same problem, so i hope someone reads this..
couple days ago i bricked my sprint intercept i was using SWu and forgot to take the Binary files for the Moment out so now i cant get my phone to DL mode, ive been searching since saturday night and have tried every Button combo posted and nothing, my phone will not turn on and ofcourse it isnt recognized by my pc BUT, ive noticed that only when its plugged in to the computer after trying to power it up several times it´ll vibrate then the 4 touch buttons will react to either the call or end button, also it makes the low battery sound and if i press the camera button it makes the volume sound but i CANT get to download mode, can i bring my phone back or is it done with? help please! and thanks in advance...
well, i would say boot into rrecovery by making the phone off either power button, or remove and replace battery.
next, you will need to press and hold in order: power/end call, call, and volume down.. this should boot recovery mode.
lastly, use the red scroll device to go to reset facory defaults or factory recovery, use common sense while looking. select with clicking and use arrow back button to go back to recovery main, then reboot to system. easy as pie.
Have you tried ODIN or ADB?
I have flashed the Intercept numerous times, soft bricked more than once, I was always able to recover using either the stock bootloader, CWM recovery, or flashing the ROM/Kernel directly using ODIN or ADB.
If you are still having these issues drop me a line and I'll gather some links together that should get you back up and running.
If the phone will not boot at all, even with a charged battery, I would definately try contacting Virgin Mobile and escalating the issue. I've had plenty of luck replacing devices claiming that the device just dropped dead without notice. They are usually good about sending out a replacement phone, and on rare occasions even giving you an upgraded unit if they are out of stock.
Good luck!
Did you use Odin or the swupdater?
Bug difference. Sounds like there's a missing boot loader.

Hi, did you guys fix your bricked phones? Today I have bricked my Samsung transform (bad flash went with SW upgrade.
Only vibrates sometimes and the buttons flash a little, but no boot at all. Is there any chance to fix it? even with Jtag?

Hold the power button until you get a black screen. Download LG Mobile Support tool and the LG Drivers. Plug USB In and then hold the Power + Volume Up key. On your screen, click Upgrade Recovery. From there, you can do a factory reset through download mode of your phone.

In case you did the latest firmware ota upd,there is a topic that can solve you problem as long as you can access TWRP(even if you didnt do the ota it will,i tried that myself) Here is what you need to do.
use TWRP's "terminal command" option to run the following:
Code:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
You'll have to type that whole thing out, and be VERY careful with spaces and punctuation. One wrong letter and you could nuke your phone.
This will probably fix you problem when it has to do with any update.
Thanks for the responses. I finally fixed it.. I started the procedure from scratch with a new laptop and somehow it worked lol

It happened to me and now phone hanged in download mode and can not connect to pc. Did you have a solution?
Solve
Guys! I had the exact same problem today. My solution was to keep pressing the "try again" button every time the error appeared on my computer screen. It took some time but the error was appearing at different levels each time in this order : 45% 57% 65% 80% and next the instalation was completed. If it doesn't work try switching to another computer if you can. After the firmware update hits 100% your phone will restart and the LG logo will appear(the led changes its color during this process). At this point you have to just wait a while. Then a dialog box will appear saying that the applications on your phone are configuring themselves. After that your phone will start and work normaly. The cause of the error is the lack of memory on your phone. If those idiots working for LG would say "YOU DON'T HAVE ENOUGH STORING SPACE" this stuff would not happen.
The phone is not rooted!(IMPORTANT)
Phone name: LG G2
Phone model: D802
Old software: 4.4.2 (KitKat)
Actual software: 5.0.2 (Lollipop)
I hope this hellped you solving the problem.

My LG x power died and I went to plug it in and a screen popped up saying,"Firmwire Update 0%", so I kept it plugged in for the next half an hour, and it still said 0%. I've tried resetting it and powering it off but nothing seems to be working. What do I do?

Download lg flash tool.
Download lg g2 stock firmware.
Press volume up button and insert usb cable. You will see download mode.
Open lg flash tool and flash the kdz( original firmware) through flash tool.select cse flash.
My LG V20 got stuck on the Firmware Update screen. It appears every time I restart the phone and I have to take the battery out. If I start the phone plugged in it starts normally. I was able to do a factory reset, the phone started normally a few times without being plugged in, now it's back to the Firmware screen. I can use the phone but need to restart when it's plugged in. I hope Oreo Update will fix it. I don't know much about updates, but do big updates like that reinstall the drivers as well?
Hello everyone I also have this kind of experience so many times in my g2 mini.stuck on Firmware update. What I’m doing is,
1. remove the battery to turn it off. Plug your charger and before plugging it to your phone hold the volume down and plug in until tou see the android is updating; or
2. Just simply hold the powerbutton + volume down until you see Android is updating.
I would love to see your feedback if it helps.
Salut à tous,
Yesterday, i got a problem with my LG. I wanted to change the Rom and after i finished the procedure, i got and LG Logo Loop
Here a little video a made of the Loop : http://www.youtube.com/watch?v=1ZDgzhDNBb0&feature=youtu.be
Normaly, i can change the Rom again by Hard Reseting, but when i press the 3 buttons, nothing happens.
When i connect the phone to the PC, i don't even got the sound that Win8 does when a phone is pluged in, that means that the phone isn't recongnized by the PC, and i allready installed all the Drivers.
I can't enter Emergency mode, when i press the buttons, nothing happens too.
My phone wasn't rooted so i don't have CWM.
I tried LG Support Tool, KDZ Software update, but as i said, the phone isn't recongnized, so i can't do anything.
Some people on forums adviced Medusa Box, but when i launch the app, i got as a message : Card init failed ..
So this is it.
I hope someone can help me. The phone isn't mine, so i'm little afraid of this loop .. Some people on forums said that this is a Hard Break, others said that this is Soft break, other also said that this is a Dalvik Cache Loop ..
Anyway,
Thanx in advance

mAke sure you have install all LG Software on your computer, like usb driver the important one
then download stock rom for your device
and flash it through KDZ Software update,
Try instaling drivers on some win7 pc/laptop, then try to revive the phone via kdz, because win8 sometimes has problems with drivers etc,
Btw which procedure were you using to change the rom?

Download the stock rom (original) for your phone, must know which version there is a lot of version ( V10C, V10G, V10E ...)
Use Kdz updater, if the App crash check compatibility and choose windows XP, in KDZ updater use the mode 3GQCT and phone mode DIAG, browse for the stock rom in the KDZ FILE and click Launch software update.
When i flashed the stock rom i got the loop, so i tried to hard reset it and it worked for me (power + menu + volume down or up i forgot)
Try to hard reset before flash if it doesn't work, flash it.
Okay Thanx again mate, i'll try it now and tell you
Worked ?

My G2 suddenly just stopped working yesterday. When I try to power it on the phone either freezes shortly after the boot screen, gets to the homescreen then shuts off, or boots to an all blue screen. I can access TWRP but haven't been able to fix it with anything I've found. My pc isn't recognizing the phone so don't know if I can flash another rom. Also tried factory reset with no luck. Any help please this is driving me crazy!!!

Ok, since there is little to no information out there I thought I would share how I created and fixed this problem.
I received a new phone under warranty because of a failing sim card reader. Naturally, the first thing I did once I received it was root it. Next, I thought I would be slick and use flashify to flash a custom recovery (TWRP). Little did I know, with the new version of Android, our phones have a locked bootloader. I freaked out when I saw some weird error messages about it and tried to power off the device in the middle of it booting. BIG MISTAKE. In hindsight, I am assuming that it was re-flashing the factory recovery when I powered it off.
It gave me a solid blue screen for two hours, unless I held the power button for 10 seconds, which would just repeat the process from black screen to solid blue screen repeatedly. I tried to reboot into recovery for 2 hours by holding volume down and power. 2 HOURS!
At that point, I realized that I may have some luck getting it into download mode by powering it off, then powering it on with volume up and power and plugging in a USB cable. VOILA! It booted up normally (somehow) and I got it running the OS.
After that, I made sure that I did a factory reset by reverting to stock using the LG Software Upgrade tool.
The moral of this story is, if you are going to try to install a custom recovery on 4.4.2, make sure you know what you're doing. It turns out an app called AutoRec did the trick for me.
dsljk2009 - I hope this message helps you, or anyone else who may think they've bricked their phones.

I didn't get the blue screen but I kept getting the security error screen on my d802. To turn it off, I kept holding down the power button for about 10 seconds after the screen went blank. This caused the phone to remain powered off. After that, I was able to boot into download mode. Maybe this method will work for your phone.

Don't know of any other methods because holding down the power button got the phone to turn off and allow me to get into download mode. From download mode, I was able to restore a stock 5.01 ROM to my phone via LG Mobile Support Tools.
LG G2 Bluescreen then no boot after disconnecting battery
Found my LG G2 with a completely blue screen. It would not turn off. Took it apart and disconnected the battery. Reconnected the battery and there was only a blank black screen and the phone would not boot. Zilch. Even with pressing the power button with the volume down to boot into recovery.....still zilch.
I sucessfully got my phone to work again using a hair dryer trick on an LG G3, which I found here.
1. I took the back off the phone, disconnected the battery, and removed the SIM card.
2. I then used a hairdryer on high heat and blew the heat over the uncovered areas for 10 minutes.
3. I let the phone from hot to warm, reconnected the battery and put it all back together with the SIM card replaced.
4. I booted into recovery and restored a TWRP backup, and my LG G2 is working like a champ again.
Ok so before I started writing this I had only one problem now I'm worried my problem has gone from bad to worse.
I updated my 6T to 10.3.2 from the latest Beta after the process it prompted for a restart, upon restarting it got stuck in the boot animation. I tried going into Recovery and Download mode unsuccessfully so I went through the forums a bit and saw that someone who had the same problem successfully entered Recovery mode by pressing VOLUME UP+DOWN+POWER buttons simultaneously, I tried to do the same and my phone turned off and now it doesn't turn on! :crying:
Has anyone experienced this or know how to fix this? Any help will be much appreciated. Tia!

These should be clarified:
Volume Up + Power while turning on will boot to fastboot.
Volume Down + Power while turn on will boot to recovery.
Holding Volume Up + Power should force the phone to turn off.
Volume Up + Volume Down should put your phone in Download mode for the MSM Tool.
Turn the phone off, let it sit. Then try turn it back on. Any response?
try to shutdown phone ...hold vol+ and power button for like 15 sec and restart your phone if this didnt work then u can try MSM tool
Thanks guys, got it working using MSM Tool!

You are likely going to lose your data. Know that going in if its not already backed up.
If you have the fastboot menu you can use the fastboot roms.
Or my least favorite option or what I would try last, MSM Tool (Tmobile 6Ts use a different tool).
IMPORTANT if you want to try and recover and data off your phone first, go to fastboot, and try and "boot" the TWRP img (not the installed one, one from your PC using the fastboot command). If that works you might be able to recover data. If that does worm, try dirty flashing the last ROM you were running and see if it boots.
No worries!

Hello, I am sorry to hear of you having this issue, I just went through 3 1/2 days (off and on) of recovering my T-Mobile OnePlus 6t which I found a way to get my unlock code within 2 weeks of having it, so I rooted it and put a custom kernel on it, stuck on 9.0 never let me update as I was not familiar with A/B partitioning, yet! The answers I saw to your questions were spot on, I just had a little to add to it and I'm sure I am not alone. Real quick let me list what has gone wrong on the rare occasion it hit the fan with the 6t...
- When I would accidentally and rarely let my battery die it seemed like it took forever to get it to reboot, I mean it sat on my desk of DOA devices for 2 weeks!
- It often seems like the buttons do not always respond properly and never have when I needed them to. Been through this before, I've bricked and unbricked and flashed and re-flashed and wiped all weekend and I like Android 10 and all but seems everything is different for every build, and everything seems to have to go in the right order with the exact right file or you wind up in a jam, period..
- That said, the previous person that answered your question has likely encountered similar, I've heard of right down to the buttons not physically working, but I have been a Smart Device Master III Technician for over 5 years, i know my buttons were not broken.
- Most likely culprit that I just handled and worked, i did have to use the MSM tool, several times - and re-unlock the BL, several times I would not even get the chance to get to fastboot, just a screen saying Build and Hardware not a match"" in yellow letters and it just bootlooped. No fastboot is no good, but when you said the tool would show some signs of working but then not, I have 2 solutions that I needed on diffrent occcasions.
1 - As mentioned fully try other USB cables, and ports, if you pull the usb-c out of the port and hold <power + vol up + vol down> eventually it will do something, very picky, sometimes gotta move your fingers to different spots on the buttons and also after 15-20sec let go of power and hit and hold it again... after a few seconds before it vibrates stick the cable in connected to your PC and the screen will be black (obv) but the msm tool will pick up on it. I know about the cables because I take good care of my phones and cables and charging ports, however on my final fix today it showed in msm tool it was connected but waiting for device.... Fed up i put the phone down and moved the usb cable a little bit and it picked up on it and did its thing! That part was just the cable, getting into qualcomm mode or w.e. is a bit tricky sometimes.
- Also someone said set it down for a while and come back to it.. THAT WORKS!! Let it fully charge and often just plugging in charger turns it on, bootloop soft brick or however have you, very simiilar to an Apple device and their DFU (don't f up mode cause screen is black..)
I hope that helps you get in touch with your family and friends.. Whatever you do, don't give up bc if you have not got it yet, you will! One other note, there are a few different msm tools available and they look the same some same size, but the one that supposed to work on my phone didn't and one that they say only a fool would attempt to try actually saved me, so if all else fails, use a different msm tool/usb cable and you will get it! I don't think I can post links yet I am on here very rarely, but plan on more! I have received so much help from XDA throughout the years on thousands of phones with just software issues alone, aas well as guides to my own phones. I would be honored to give back as I also have some extensive knowledge on many devices but I am a noob in comparison to many! Stay safe, good luck and please update and let us/ me know how it worked out for you. If i can help further I will, I have every firmware file for the OP6t, recovery, tools, software, this is not new to me but I feel your frustration!
