[Q] Soft Brick Huawei Y320-U151 - General Questions and Answers

I was watching a video on my phone when all my apps made a pop-up saying "Unfortunately *app* has stopped working". This happened for every app, I tried to factory reset from recovery mode because I couldn't access Settings, but when I did the factory reset nothing changed and the problem persisted. I decided to just leave the phone and the next day it wouldn't turn on at all no matter what and when I tried to charge it and left it for two hours it seemed as if it wasn't charging because the temperature of the phone or the charger didn't change so I came to the conclusion that my phone is bricked. When I plug the phone in by USB to a computer, the computer makes the connected sound.

Any Updates on what happened with your phone?

Hello. Your phone uses MTK Cpu? (You can see in gsmarena and if ur cpu for example is MTxxxx)
If yes then install VCOM drivers for your phone on pc (works well on windows xp) after that see if pc finds your device or not (in device manager u can see that) if the pc finds it and there are no problems u can flash it with SP-Flashtool .
and if no, it means there is an hardwere problem (it happens when phone falls on ground and etc...)
You can find a guid on internet for flashing your phone
Sorry i didnt explaind everything and sorry for my bad english

[Q] Super Bricked O3D, Dead No POWER & Not Responding

My phone is dead after switching external sd with internal sd via CWM script .zip file and a little tinkering in the phones system files.
(“I have done this before with success but had just flashed new firmware, and in the rush I was in wile doing it I obviously did something majorly wrong and super bricked my phone”)
After rebooting to complete a step I was doing, the phone did not turn back on, the pc does not detect it properly anymore, no button combinations work, such as pressing vol up when connected without battery, power button and pressing up + vol. No RESPONSE:.
when plugged into the pc it just flashes "OMAP4430 device" but appears and disappears all the time in device manager, now I know all drivers are correct and how to go into download mode, recovery mode and every trick you can with the O3D but none work anymore, phone does not turn on and it only recognizes it for a second showing “OMAP4430 device”.
PS Sorry for the new thread but I have searched the forum and the internet with no real answers, it would be great if there’s a fix for this situation or is my O3D dead to the world never again to be reborn.
NOW IF ANY ONE HAS MANAGED TO FIX A TRULY BRICKE O3D LIKE MINE PLEASE HELP!!!!!!!​
sounds like a harware brick i did that to my thrill had to take it in
That’s what I’ve been fearing, my other issue is that the phone is actually a LG thrill from at&t I just call it a O3D because in Australia were I live we only have O3D, and let’s face it they are basically identical, any way would that mean I would have to send it back to the USA for repair?
well is it under warenty? if so youll have to send it to who ever you bought it from. if it isent ull have to get a new logic board and relace it your self or have some one relace it. or send it to lg to fix it
I had a similar problem when installing rom. KDZ:

The problem with "OMAP4430" device I solved by connecting the phone to the computer via a cable from HTC Wildfire (such problems I had with the original cable, LG).
It can change the cable will solve the problem.
I wish you luck.

You have to remove the battery when omap flashes on device manager let go off the button and push and hold it agen it should stay. try this time omap like have your cursor ontop of omap4430 as soon as it appear quickly right click properties and find the driver unplug reconnect it will install the driver when it detects it agen i think with this phones its impossible to hardware brick the phones if only it was easy like samsung just plug in download mode let drivers install and push start button done. if flashing a phone was like a movie lg would be inception
trust me i totaly bricked my phone i tryed every trick pulling the battery out and putting it in in download mode problem was omap didnt even show up just the other one and it would flash on and off way to fast to click on it in device manager then it would just stop.
So did you end up taking it in?, it should still be under manufacture warranty well hopefully I got it in october and I don’t even think the O3D has been out for a year yet.

The problem is that it only starts flashing with the battery removed so, and I can’t get into download mode at all, which is when it normally stays there and detects it properly, otherwise the drivers are all installed.
If it flashes omap its not a complete brick. If all fails try the resistor cable. You can find a post around in the forum
I have tried the resistor cable using 910k resistor, and I even checked it on the multimeter and it reads 908k resistance which should be ok since I think you can allow for a 1% difference.
I could figure out that ur device can be detected as OMAP, this means it isn't bricked totally, please be sure U remove UR battery, connect ur USB--phone side, then press volume up and insert the USB--pc side while pressing the button and continue pressing while ur pc is installing, first it will show OMAP, then after 10-20 sec it will show COM added, don't stop pressing until it finds the COM and installs it, then directly stop pressing and insert battery and don't try to turn it on and start flashing as usual
try to use other USB cable model like sony ericsson, it never failed me
hoping U will be lucky
See the problem is that no button combination work on the phone, pressing a button is like talking to a wall you get no response lol.
I have the same issue and I bought my phone off of Craigslist.. is there anything I can do? I cannot send in via warranty because I do not know when the phone was bought.

its hardware bricked need a new logic board sorry to say
Hi, i had the same problem while upgrading to gingerbread. What windows version are you running? Ihad the same problem using win 7 x64. Got to a win xp computer with no lg software installed and used the tutorial of unbrick from this forum. had to try several times, but at least step by step my phone got back to life. Main thing is to get omap drivers installed on XP with no battery. Then taking the other steps mentionened under unbricking your phone in this forum.
Hope it helps
I have the exact same problem and NOTHING works.
Just to clarify everything, you guys had the same problem where the OMAP4430 device appears and disappears over and over again in device manager and by doing what you all describe, the phone got brought back to life?
Because none of those things work for me, I even tore an old sonyericsson phone apart to get the phone pins connected to my O3D battery and see if the old phone turned on, which it did, so the battery does work.
I installed the OMAP4430 driver without any problems and I guess from here, everything seems to be working for you other guys, right? Because the OMAP4430 is still getting connected and disconnected 10000 times BUT as a "Known" device which has the driver installed.
No need to answer this with "you need to send the phone to LG". Just want to see if I'm on the same track as the guys who got their phone working.
Btw, mine got bricked when formatting the external SD card with CM. Seems as if CM formatted something else..

So let me get this straight. Like a few months ago, there was a way to completely destroy your phone:
install CWM and run an OTA update on stock rom.
That completely ruined my phone. It was explicitly said that no unbrick method is available.
Now I hear several people reporting yet another unfixable brick, caused by
- Erasing your SD card through cyanogenmod
- Formatting /data ?
All the available methods of unbricking are said not to work. And by those methods I mean
- Opening recovery and do a factory reset (recovery can't be opened I heard?)
- Connecting to a Windows 7 PC with battery out and volUp depressed (device disappearing reappearing)
- Connecting to a Windows XP computer With battery out, volup depressed (Same problem as Windows 7?)
So to put it simple:
Doing some things with CWM OR CyanogenMod can render your phone unfixably bricked. There is a genuine risk in hard bricking your phone when you have CWM and/or Cyanogenmod installed.
I'm not going to install either of those for that very reason.
If the omap 4430 is detected when connecting the phone, then the phone should be recoverable. Try another pc system and then use the official lg recovery tool entering the imei number which should hopefully restore the stock rom.
Can i clarify whether or not any other devices appear in the device manager (Remember to hold the up button without battery until these appear and then insert battery after
The entries in device manager that should also appear would be something such as the following (This would probably vary based on whether in normal connection mode or flash mode)
PORTS
LGE android platrom usb serial Port (Com x) x may vary on system
UNIVERSAL SERIAL BUS CONTROLLERS
LGE Android Platform Composite Usb device

They said that the omap driver keeps appearing and disappearing. You can't do anything if a driver does that!

Wont connect to PC and other odd issues

Ok, so I have been having a very annoying issue(s) recently with my SGH-I997R, ( Firmware version 2.3.3, Baseband version I997RUXKG3, Kernel Ver: 2.6.32.7-I997RUXKG3-CL366622)
This all started out of the blue about a month ago, I used to connect my phone to my PC all the time for transferring items via Mass Storage, and then on day when I went to connect it to my same PC, I got " USB Device Not Recognized". It will charge the phone but will not connect or show any option on the phone to connect. I have tried 2 Samsung cables and a generic Micro USB cable, No change. I tried connecting to my laptop, same issue. I re-downloaded the drivers from Samsung onto both my usual PC and Laptop, no change. Very very frustrating.
Other issues, I don't know if their related in any way but they all started at the same time.
a) if I place my phone in airplane mode i cannot get it out of that mode without rebooting my phone
b) if i shut my phone down (doesn't matter if battery shows 100% or 25%) I cannot get the phone to turn on without plugging in the USB cable.
c) When I leave my phone charging overnight and look at it in the morning, battery shows 100% but also shows "NO SERVICE" , I reboot the phone with the cable still connected, service restored.
IF anyone has had these issues Especially the connecting to PC issue, Please PLEASE help. I am going nuts. And of course this all happened 3 months after the warranty expired, so both Rogers and Samsung will not help without $$$$$.
have you tried to back up your data, take out any micro sd card and perform a factory reset under /settings/privacy/reset ?
or open it up and look inside for any problems like corrosion?

I have done a factory reset numerous times from both the /settings/privacy/reset, and from booting it up holding the volume keys and doing a reset that way.
And I have had my phone since day one in a Ballistic Hard Core Series case, I take it out once a week to ensure its clean and free of dust/moisture (I work in construction so I try to keep it a clean as possible.) and my phone still looks like its brand new.
Thanks for the response though,
Update:
So just as an update for anyone out there who may be able to assist me with this very annoying issue, the Phone is still doing the same things, and since the last post i've also replaced the battery to see if for some strange reason it might help.
But to no avail.
As well I dont think i mentioned that this phone is rooted. I want to try unrooting it to see if that will correct the issue, but with not being able to connect the phone via usb to the computer, I have NO IDEA on how I can accomplish this. Any help???

PC not Recognizing S6

tl;dr - Computer does not even acknowledge the phone exists, factory reset doesn't work. The cyan colored recovery is recognized by the computer though.
So yesterday I went on a hike, and before you start assuming "Oh he dropped his phone in the water or dirt or something" no I didn't. The hike is more of a tourist attraction really, with a man made path that you really can't miss... more of a stroll in the forest than a hike. So as I reached the end of the trail, I put my phone into Ultra Power Saving Mode as I needed the battery. While I was texting, the phone started acting up. The charging sound kept on coming on kind of like when a charging connection is sh**. Then the screen went black. The weird thing was though, that the screen was "on". I could attempt to capture a screenshot,and it would say "Unable to capture screenshot" in a message box on the bottom, and the ringtones would still go off. The phone stayed like this for a while, when I got into my car I noticed it seemed like the phone was charging from the car port, but the charging light was still on when the charger was unplugged from the car (which shouldn't happen normally). After I stopped in town, the phone worked again, but I had to rechoose my keyboard, theme, and wallpaper. I thought all was fine. However when I got home I noticed I couldn't connect my phone to my laptop. It would say charging, but Windows doesn't acknowledge the phone and I can't choose MTP or PTP on my phone.. it just says charging. I am 99.9% sure it has to do with what happened on the hike because it was working fine before. I tried a factory reset/cache wipe and going back to stock ROM (from CleanROM). Still not recognized. I tried toggling USB debugging, pretty much everything the Internet has thrown at me... I'm past my 14-day return period so I hope this isn't a problem over the next two years?
Yes... different USB and computers don't work. Samsung drivers installed. Kies and SmartSwitch don't recognize the phone. Tried rebooting both phone and computer. Using original cable that came with phone. I've pretty much exhausted everything... If I didn't list it you can suggest to see if I didn't try that.

Same problem but no previous reasoning behind it. I have installed the samsung galaxy S6 driver for windows and I get a beep on my PC when I connect it but no detection of device. I have enabled USB Debugging and clicked on connect device as Mass storage device.

Note 4 Bootloop - Softbrick

First, I will say that I have done an extensive amount of searching and reading about boot loops and issues with the Note 4 before posting this. After days of dead ends, I have to ask for help...
About a week ago (end of January 2017), I installed the Verizon security patch update for Android 6.0.1 for my Note 4 (SM-N910V): MMB29M.N910VVRS2CQA1. Everything was normal until this past Friday night, when I used a flashlight app (had been installed since I had the phone and used often) and it spun into a bootloop. Battery was at 20% at the time, and since I've had the phone, the battery quickly discharges below ~15%.
Situational Details:
Anyways, the bootloop goes all the way to the home screen, and often the touchscreen is active for a few seconds (varies) before it freezes for 5 seconds and continues the bootloop. It's worth noting that during the bootloop, the screen gets incrediby hot at a specific point: horizontally across from the power button and vertically below the light sensor.
Also, I'm able to access the recovery menu, download menu, and boot menu. Also, when a power cable is connected to the phone (with battery inside), the phone screen shows the empty charging battery symbol and then immediately turns on, without me having to press the power button. After that, the only way to actually power off the phone is to remove the battery or let it bootloop until it dies.
So far, I've tried the following without success:
-Wiping partition cache
-Factory data reset
-Flashing stock ROM with Odin. Though Odin recognized the device in the USB port and it accepted the ROM which I loaded it with, there was no activity from Odin to the phone once I clicked "Start". I'm using the original USB cable that came with the phone (the one that I charge it with), and the USB port is working fine.
-Using Kies3/Kies2.6/Smartswitch to revert back to factory stock ROM. Though Kies3 is allegedly the correct software, they all display an error message that my device is not supported, when I attach a USB cable to my laptop from my phone (regardless of USB port).
-When using Kies3 to try Tools > Firmware upgrade and Initialisation, Kies accepts "SM-N910V" as the model number, but it displays an error message that my S/N is incorrect, though I am copying and verifiying the IMEI from under the battery compartment (I also registered my phone with Samsung using this IMEI, so I know it's valid).
-Wiping partition cache 5x + Factory data reset 5x before rebooting
When in the recovery mode, the current android version MMB29M.N910VVRS2CQA1 is listed, which I find incredibly bizarre, since I thought it would have flashed to the stock ROM after a factory data reset. *shrug*
It's crossed my mind that the exceedingly hot temps may be causing the boot loop, but genuinely do not know if that's true or why it would become so hot in the first place. Either way, I just want to toss the idea out that maybe I have a hardware issue that's causing such overheating.
Anyways, at this point, I'm totally confused about what to do, especially since it's not totally bricked. Any/all help is greatly appreciated.
Anybody have any thoughts at all? I'm more and more open to the theory that it's overheating and causing a boot loop. When it's been sitting for a long time at room temperature, the screen remains at full brightness on the Verizon splash screen, and does so until it gets stupidly hot near the microSD / SIM slots... then it boots up for ~5-15 seconds, freezes for 5 seconds, and boot loops again.
I may try to thoroughly wrap my phone in plastic wrap and apply an ice pack before attempting to use it again. I find it hard to believe that the culprit is batteries since the issue happens with both batteries that I have (purchased separately at different times).
Ok, I had my Note 4 totally cold yesterday and booted it up normally. I discovered a few things while playing with it:
When the first reboot happened,the usual hot spot was hardly to room temperature. I tried this exact same test again this morning, with the same results... the hot spot was not even to room temperature when it froze and rebooting.
It's worth noting that I figured out the screen does not freeze if the display is constantly moving, regardless of phone temperature. For example, I normally try to do something/anything prior to the phone freezing and rebooting, like establish a file transfer type usb connection to my laptop, instead of the default 'charge' type connection. Well, to go through the settings menu and pick out the connection type, the screen will always hang for a split second as it loads the next set of menus. Normally, it would freeze at this point and reset. But today, I decided to click on the Apps button and oscillate my finger on the screen to flip between pages of apps... and it worked for several minutes straight.
I know my problem seems incredibly strange, but do any of these symptoms have any plausible explanation? I'd hate to think there is literally nothing that I do and that my $$$ Note 4 phone is now a brick.

Do you have USB debugging turned on? Do you have all of the USB drivers for Samsung phones installed? Are you using the stock USB cable when you use Odin?
If you can't get Odin to flash your firmware(it has to be the same version you have or newer, it can't be older), then you may have a hardware issue that is a result of the excess heat you mentioned.

I didn't have USB debugging turned on before. I turned it on (under developer options... which I barely have time to access before it restarts), but now both my laptop and desktop won't recognize the device via any USB port. I do have the USB drivers for Samsung phones installed and have re-installed them a few times, to be safe. Also, I am only using the stock USB cable when doing any of these things.

Assuming you mean the device manager in Windows, it's only showing as "Unknown USB Device (Device Descriptor Request Failed)".
Two new interesting notes:
When I enter Maintenance Boot Mode (Down Volume + Power to boot) and select USB Debug Mode, it now just performs a normal reboot. I can't recall for certain if this was any different in the past.
When I have the ability to access Developer options, I can definitely see that USB debugging is checked. Also, when I select 'USB configuration', 'charging' is pre-selected by default. When "MTP" (media transfer protocol) is selected, the developer mode menu still displays the value as 'charging', even though subsequently accessing the 'USB configuration' sub-menu shows that MTP is selected. Weird.

Have you tried booting to safe mode, if it boots to safe mode then it's a user app or a user app update that is causing your bootloop. In safe mode you can uninstall whatever app or app update caused it.

Yeah, I thought about that, too. I've tried safe mode even after factory resets + cache wipes and it still boot loops. ("Safe mode" does indeed display in the bottom left of the display/GUI) Good thoughts, though.

Starting to sound like a hardware issue.

Samsung J7 Prime G610M - FAP Lock + weird usb problem - Urgent

So, something very weird started happening to my phone. Out of nowhere, about 7 hours ago, it would stop charging whenever it was on, charging only when it was off and connected to my laptop. However, I thought it was just something wrong in the dev options, and I went to change whatever was the USB option to "charge phone". With this, I did accidentally forgot to activate the OEM option, and had to reboot not long after. You can probably see where this is going now.
Now I have a phone that bootloops on the FAP Lock message, and whenever I go to download mode to fix it, my PC just doesn't recognize the Phone. I've tried different USB cables, all of them are only recognized when the phone is shut down. So it isn't a hardware problem, because the Phone actually charges when it's shut down, and it isn't a problem with my USB ports or cables, as anything else I use with it works fine. And the worst part is, I need this phone today for a serious bank matter, and I can't afford to lose any data on it either, there's some very personal important stuff from yesterday that wasn't backed up yet. And keep in mind that paying for it to be fixed is the last option for me, as I can't afford it (besides, I fear they might end up getting the phone in factory reset mode, and I can't lose that data as I said).
Any kind of suggestions on how to get either the PC to recognize the phone, or flashing in a different way that doesn't need the PC to recognize the device? Thanks in advance.
Edit: Whenever I try to connect the phone via USB, it doesn't even make the Windows "USB connected" sound, it's just like it isn't there at all. One time, I got it to show, but it was as a "unrecognized usb device", and I haven't been able to replicate it yet.
