Phone specs:
Model: LG Optimus One P500h
Carrier: Telus (Canada)
Android version: 2.2
Kernel version: 2.6.32.9
Build number: FRF91
Software version: LG-P500h-V10g
Background:
I bought this phone (brand new) in late November 2010. Within a week or two the phone started randomly powering itself off (even when the battery has plenty of charge left and the phone is just sitting on my desk). I hadn't performed any modifications at all (no rooting, no custom ROMs). Hadn't even downloaded any apps by that point.
I have never seen it happen... I'll use the phone like normal, the screen saver blacks out the screen like normal, and then I go to use the phone some time later (a few minutes, an hour, etc.) and I find that the phone has powered off on its own. It happens when I have the phone sitting on my desk, so the power button is not being pressed accidentally. The frequency is intermittent: sometimes it will go for a few days with no shutdowns and then sometimes it will happen twice in one day.
At first I thought it was a battery problem (I thought maybe the battery was overheating and the phone was shutting off to cool down) so I went to Telus and they gave me a new battery. I tried that for a week but the problem persisted. So I took it back to the Telus outlet again and they sent it away to an LG-authorized service center for repair. Doing this cost me $30 for shipping + service charges because I didn't purchase an extended warranty and I was 1 week past the 30 day device exchange period.
When I received my phone back (the service bill said that a "software upgrade" had been performed) the problem still continues! The phone has been shutting down at random exactly the way it did before it was sent away for service.
I didn't want to send the phone away for service again so I tried updating the phone's software myself - hoping this would stop the random shutdowns. I downloaded & installed the proper USB drivers using the LG Mobile Support Tool (I needed to put the phone in USB debugging mode in order for the mobile support tool to detect the phone). Everything was going fine, the LG Update Software downloaded the ~100mb firmware update file (I think V10s) and proceeded with the install but somewhere near the beginning of the install the phone went into Emergency Mode and stayed stuck there. I left it alone for 30-45 minutes just in case this was part of the install but after the program stopped responding I figured this wasn't normal. So I unhooked everything and took the battery out hoping it would reset itself but every time I would power the phone on it would bring up the LG screen then proceed to a bright yellow screen with the text "Emergency Mode!!" displayed.
I tried a few methods to get the phone out of emergency mode (hard reset/factory reset, leaving the unit off for extended periods of time, trying the mobile support tool again, etc.) but nothing worked. The only way I was able to get the phone operational again was to download the original firmware (V10g), install the MS XML sp3 parser and run the KDZ software updater (with phonemode "EMERGENCY" selected).
So with the phone running like normal again I figured I would try the update again. Now when I connect the phone and run the LG Mobile Support Tool it says a new software update is available but then when I click on "Start Updating" it goes through it's initial checks then says that this model cannot be updated, and it won't even attempt to download the new firmware update.
I have found the V10s available here: http://csmg.lgmobile.com:9002/swdata/WEBSW/LGP500H/ATLSRB/V10s_00/V10S_00.kdz
But I am hesitant to try and install it with the KDZ updater in case something goes wrong.
My questions:
1. Is anyone aware of a fix for the random shutdown problem? I read through this thread
http://forum.xda-developers.com/showthread.php?t=944847&page=2
but I didn't see any concrete solutions.
2. Do you think the V10s software version will fix the random shutdowns?
3. Can you think of anything that I'm doing wrong? Why won't the LG Updater let me install the update now?
Thanks
unlikely to upgrade to fix something, most likely factory marriage.
before upgrading try to make a hard reset
when the flash in KDZ try disabled LG Modem Driver
Maybe a problem of a bad SC-card. Try a different one (insert the new one and format it in the phone, then copy the content of the original one via usb)
Thanks for all of your suggestions.
I'll try installing with the LG Modem disabled.
If that doesn't work I will purchase a new sd card. I'm still using the stock one that was provided with the device so maybe that's causing the problems.
Hello
E recently bought an LG Optimus Black (P970). It had stock rom 4.0.4 and the guy told me that it has CWM recovery on it, but i never tried.
It was working well, but one day it started to freeze quite often. One day i inserted another sim card than the one i was using before and it freezed. Restarted the phone but it froze again. The third time it didn't even boot, but instead the green android appeared with his belly open and the exclamation mark hanging out of it.
I tried a factory reset, but the process lasted more than 15 minutes so i turned off the phone.
Since then, when the phone starts the following happens: LG logo appears, Android guy appears with the loading sign in his belly and after 3 seconds the lg logo again.
I was able to access the SWUpdate menu and to flash a stock ROM with LG MobileSupportTool. When the update process ended with success, the phone should have restarted itself but it didn't. Instead the lg logo appeared again.
Trough the SWUpdate menu i managed to flash other stock ROMs on it with the SmartFlashTool but the same thing happened as before. (Successful flash, but the phone didn't restart. I even managed to flash a ROM on the device which had CWM recovery patched to it.
After this i created myself a 3in1 service cable with 56kohm,130kohm,910kohm resistors. I managed to access the SWUpdate menu with it, so i knew the cable was good. But i couldn't read from the device with CDMA tool. CDMA made the connection, but couldn't read.
I took the phone to the service, but they told me that the phone didn't respond to the JTAG either. They assumed that the motherboard is broken.
I didn't make peace with the idea that the motherboard is broken. I need help. Currently my only option is the take the phone to another service and hope that they are more capable than the previous ones.
Thank you in advance.
Hi,
I'm a new member here.
8 months ago, I purchased two "Samkimoke T710 LA-I" Android phones. It has Spreadtrum SC6820, Mail 300 GPU, 256 MB RAM, MTK6517, Camera (idk spec needed for driver? I guess).
(I know the above from an App I installed in another T710 mobile.)
The OS was said to be "4.0.2" in 'About Device', i personally think it's Android GingerBread though.
Today, I got a miss call, and after that I just pushed the Power button (to turn the display off), it did so. Now the thing does NOT start, no display while charging.
I've googled a LOT, I tried other batteries, connected mobile to USB and then inserted battery, as was said online, nothing came, I also tried Volume buttons + Power button, and also charge to Power Outlet trick. Nothing worked.
After that I went to a local repair shop, after checking it he said the phone does boot, but is not starting (i think he was referring to it's ROM), he said "he would try to re-install a software", from what I understood, he wanted to flash it or something.
So the questions are:
1. Was my phone "dead" or "hard brick" with OUT any problem/s (just out of nowhere) ?
2. Can i flash it (or even any "hard brick" Android device) myself, and expect it to work? If yes, how?
3. Where can i find a custom ROM this manufacturer used (or it's alternative)? What tool should i use to Flash?
(i guess, personally, driver issue will arise in these cases) I checked the Samkimoke DOT com website, their service is available in China only, and NO Email given for me to ask question about their custom ROM)
Thank you ...
(You can say I'm too greedy to forget that .. i can't throw a device that was working in the morning, and that's just 8 months old )
What's happening here?
I left it for the shop to flash (I've never flashed an Android before), and also since it's Chinese Android - I was unsure of the ROM. So he said he tried to flash it (or flashed it) but it still isn't booting!
Back home, I pressed the Power Button, and I noticed this.
http:\\i.share.pho.to/e7653bef_o.png
1. Before Pressing Power Button
2. After Pressing Power Button (the display starts, as if trying to display something)
3. The display fading away (back to off state -- state 1)
4. Back to State 1
All this happens within a second. Is the phone trying to launch the ROM and not finding it or something? Does the above mean it's not the Hardware issue?
I downloaded the MTK Droid Tool and it does NOT show any info, it doesn't detect it at all.
What should I do in such cases?
Thanks ....
Umm.. Am I posting this in the wrong forum section or something?

i don't think this is your fault, its just the faulty Chinese firmware is terribly developed and half of the time this happens to all Chinese phones. they decide not to work anymore or the usb drivers decide to not like your computer anymore. if there is not life from the device (no boot, no recovery) then its hard bricked. the only why you could fix it is using a jtag and finding the firmware online for your specific device and using that to write the Firmware back onto your device. but that can cost lots of moola $.

Sounds like a hard brick to me, too. Since you didn't "tweak" the phone in any way, it's not your fault. You can do only 2 things: either go to another service shop and ask for repair, or find a toolkit and the necessary firmware files to flash it on your own. From what you're describing, it seems like the firmware is all messed up.
Okay, thank you .. and I didn't tweak it, it just simply stopped working.

Where can I find/buy this thing called jtag? Or is it simply the same thing as "jig"? If not, How much would it cost?
Since I bought two of them, I have another T710 mobile (same manufacturer) working with me. I'm kinda scared for it too, should I use CWM or something and back it up right now?
Back to the topic, the working mobile has MTK6515 (as opposed to MTK6517 that the damaged one has), can I still backup/extract the image of one to use in the damaged Android phone?
Thank you ...
So, i was inserting and ejecting this device back and forth, and this time, the device decided to show up in the Device Manager, At 1st, it showed up in the Other Devices, then under the "USB Controllers" as "Unknown Device":
http:\\i.share.pho.to/80f316eb_o.png
It was still not showing up in the MTK Droid Tools, although i had installed already MTK65xx drivers. Then i installed the SpreadTrum Phone Driver, and after connecting the device, i pressed Power + Volume [+] button, and it showed up under USB Controllers as "SPRD COM Enumerator".
http:\\i.share.pho.to/3001fb77_o.png
At first, it said "The device is working properly":
http:\\i.share.pho.to/1ad975d3_o.png
And then it refreshed again and said "The device cannot start":
http:\\i.share.pho.to/dd9ee409_o.png
So this means my phone is SpreadTrum phone so maybe that's why it did not show up in MTK Droid Tools?
Which Programs are available to backup and flash Spreadtrum phones?
Thank you. .....
EDIT: I pressed the Power button in my other t710 phone, and it also does the same blinking as the damaged one does. So that means the phone was, i guess, testing if it's "on" and should display or something, and since it has no contents or has, as a member pointed out, a damaged firmware, it's not working properly..

a Usb jig and a JTag/Riff box are a little different. usb jigs are used for only samsung to force the device into download mode, otherwise known as a easy way to get into download mode. the Jtag and riff box's attach pins to Certain parts of a phone or another device and it Write firmware onto that device since its corrupt or does not want to turn on. these can cost up from $100-200, i would just get another phone my friend .
So, although it shows under Device Manager, I'm already screwed with this device? Can I not flash it by using a Computer?
Thank you ..

Nope, from what i understand when a device is hard bricked or you have nothing showing, the OS is corrupt and that means the USB drivers are Screwed up so it wont recognize your device.
Hmm ... I have flashed it a couple of times, and it's not starting because I don't have the right ROM It gives the usual short vibration when I press power button to start it. The screen is not displaying anything, as expected. and there is no light.
The device is SpreadTrum and the screen size is 4.3 inch, the roms I downloaded either seem to be that for 3.5 inch or 5 inch
1. Is there something like Custom Barebone ROM which will "work on any device"? OR at least compatible ROM?
[ I purchased the phone for 5860, "repairing" it will cost me 1500 So I'm trying to not go to the repair shop. ]
--------------------------------------------
2. I rooted my working phone with vroot, and used adb to backup the images, the total size is 309 MB, trying to flash it in my device, it's giving me "Failed: Download size is over it's partition" error or "Failed: Operation Failed" error.
Regardless of which FDL.bin file I use, my PAC always gives errors. And those that I download from the web flash fine.
(I'm using ResearchDownload -> Packet option, it makes the PAC file, but the flashing process always results in errors.)
Is there some proper Guide to make the PAC file?
Thanks ...

Hi guys, quick information:
Yesterday tried to autoroot my s7 edge with chain fires autoroot. Unfortunately I heard that it wont work on latest firmware after I tried to root it.
So I just wanted to reset my whole Phone. (Accidently) Downloaded wrong Firmware, tried to install it with odin. didnt work. writing failure. Boot loop.
Left it over night (kept it loading over night). Woke up. Phone is VERY hot. Couldnt touch it. ok. removed cable. cool down.
Ok. Noticed I picked wrong one. Downloaded correct one tried again. Didn't work.
Phone wont let me hard reset (wipe cache/ Home Button + Volume Up + Power Button doesnt work)-
Can't even get to Boot Logo-
Can only get into download mode but screen goes black after a while.
Everytime I try to install the stock firmware , progress bars in odin and on phone goes to a third and then phone screen goes black and the bar doesnt move at all. if i normally try to boot it this text shows up: an error has occurred while updating the device software. use the emergency recovery function in the smart switch pc software. Cant use it because it want me to use a serial number i dont have / people on internet said its iemi number but it wont work. on videos on yt i saw people with iemi number AND serial number. in my buying papers no information about this serial number. not on my backcover of my phone.
Don't know what to do.. please anyone help

First remove your imei. Never post that openly on a forum or you could end up getting your device cloned.
The serial number is on the box.
You might have very well full bricked your device. Flashing the wrong firmware is a short road to a brick.
The buttons won't work due to partially written software. The wrong software at that.
Your only hope is finding the box and flashing the right software or you will have to send it in for repairs which might cost you a bit.

Okay Guys, small update: Just Made my phone work again.
Had no opportunity to install stock firmware somehow for a long time- Tried to install TWRP multiple times with odin failed alot.
Worked a few minutes ago. Why it didnt work? Download Mode stops after a while.
So TWRP installed- Now i can finally open Recovery mode. It told me that there was no os installed. true. I tried to install my os again. it worked.. soo. yea.
what do we learn?
dont root if you dont know anything about your phone :good:
sincerly,
me, the noob.
I've been very frustrated, its only been like 1 year since I bought it. First, I got bootloop out of nowhere after updating (I got bootloop just 1 week after i picked up the phone from service center, the audio jack was broken at that time), then the phone is not detected on any pc. I tried downgrading from SD card, and it works at first, then the phone restarted itself, then I got bootloop again. I tried the same method (upgrading and then downgrading) then it showed warning that the phone is in Red State when i entered Android Recovery. It says the phone is in Red State, it is corrupted and cannot be trusted, it gave me a link that doesnt solve my problem. The question is, is this the end? do I still have hope? or should I give up and let it die?
