[Q] Blackscreen after LG logo - Optimus L3, L5, L7 Q&A, Help & Troubleshooting

Hello! Ive got an extreme problem with my Optimus L7-2 (P710). After trying to swap the external and internal SD card (remapping), I'm only receiving a blackscreen after thw LG logo on boot. I just swapped sdcard0 and external_SD in the file (forgot its name though), and changed one boolean in the build.props to true, which forced something with the SD card (forgot this too, at least Ive tried to swap my two SD cards to receive storage). Now, Im getting the blackscreen after the LG logo. What Ive tried:
- Home + Volume down on boot = Android guy appears, but disappears after a few seconds and the device reboots
- Home + Volume up on boot = Recovery mode. Nothing more. It just says that I should press power 8 secs. I do, and the blackscreen comes again.
So, could anyone help me with this? How can I restore it and swap the two SD cards again (the problem is obviously, that i cant find the system files)... Thanks!

if you have a nandroid backup restore it by cwm else you need to flash the firmware with kdz

I got it working again by myself a few minutes ago. I flashed the firmware with KDZ updater. Worked, no blackscreen anymore! Thanks anyways! :good:

Galaxy S i9000 (Bell Mobility) wont start

Galaxy S i9000 (Bell Mobility) wont start. Rooted with LagFix.
HELP!!! I cant get anywhere. Can anyone solve this
What happens: it starts up with logo and sound and then to a black screen. Any attempts end up with the same result
What I did prior:
1 installed CacheMate for Root Users and busybox
2 tried CacheMate for Root Users (didnt want it)
3 uninstalled busybox (when I installed, I noticed it showed 2 other versions installed. I searched and manually deleted them)
4 phone shut off unexpectedly
How I tried to fix:
1 tried to reboot
2 pulled battery tried reboot
3 pulled sd card tried reboot
4 pulled sim/sdcard tried reboot
5 vol+ home pwr
6 vol- home pwr
7 pwr menu
8 even tried heat up trick in desperation
vol+/vol- + home + pwr are disabled
can't restart to apply 3 button fix > can't get into recovery > can't reflash without 3 button recovery
do you remember if the USB debug mode is enabled or disabled?
if it's enabled, then you can let it boot and do the
adb reboot recovery
or
adb reboot download
if that doesn't work the only way to fix is to send it back to the store for repair
If it goes to the Logo screen, then when it goes black if the back and home buttons still light up your internal sd card has crashed and you need to send it in for repair at bell

This. Been there, done that, wrote the book. Me and my buddy. Stock too.
Sent from my GT-I9000M using XDA App
It's bricked... internal SD is fried.
To confirm, if you can get into Upload Mode, flash a 2.2 ROM, which will give you the ability to get into Recovery mode... once in recovery mode, it will show you the Internal SD error that I'm talking about...
Take it back to the store before your 30 days are up - no use trying to waste time fixing it...
Happened to me as well. I was on my 10th+ firmware flash. Went to JPD or whichever 2.2 came right after JPC. I install RyanZa's OCLF and within one hour it crashed and wouldn't boot.
I was able to run JM8 or any 2.1 Firmware but without Internal SD. I was just running off the internal 2gb partition that it created off the external SD when it can't find the internal SD. Thats why when the internal SD is corrupt, the phone won't boot into android without the external SD installed.
In the end it was 2 days before my 30day replacement, so I took it to bell and had it replaced.
Running stock update 1 for bell (JH2) with Voodoo 4 on current replacement.
Hey, I also have this problem. I originally bought it semi bricked. The phone was not even showing the boot screen, but I managed to flash so now it does the above.
What are mu options here. Im not a Bell Client so they won't give me a replacement. I'd prefer not to spend money sending it in, but will if i have to. But i doubt that bell would take it in even if I did pay because im not their customer...Telus obviously doesn't support the Galaxy so I can't go to them either.
How were you able to get it running off your memory card? I don't mind doing that actually!
I had this happen to me once before and and i did a factory reset and i worked perfectly! and now its happened again and i believe my internal sd is fried! kinda really sucks

U8800 Internal Memory freezed

hi guys.......
my phone issue is still not solved.
i have a U8800, came with 2.2.1 b136 rom. all things used to work fine and one fine day while i was out and the battery drained off, Returning back home i plugged my phone to the power and kept for charging as usual. in the morning when i power up the phone it started but got hanged up on the android text animation screen and then a loop of same. from that day onwards my phone is not working.
it starts up showing big huawei screen and proceeds to the android text animation there it get stuck for a few seconds and then again back to android text animation continuously the same.
I can get into the pink screen bu pressing Vol up + Vol Down + power.
I can also get to the blue screen Vol Up + Power.
i cannot change any thing in any of the drives or partitions in the pink screen. the image folder (in the pink screen), and other partitions also all the 4 partitions are freezed. even if i delete or replace files, the previous files comes back the very next movement. as if the memory is freezed. i even tried to format the 253 MB partition (image folder partition) but format gives error cannot format this drive , checked the attributes is unchangeable read only partition.
i tried updating official rom 2.2.1, 2.2.2, 2.3.5, but update failed, Some times even it reaches the update process to STEP 2/2 and there its like hanged the progress doesn't moves further even tried keeping hours, also tried update without battery but the same.
OK logically i assume i cannot update if the partition is read only. but why is it.
it used to be a working phone worked well and once sudden day its like.......
Is my phone bricked and what i can do to get it on. please help.
i cannot go asking for warranty as it is already out.
i am been asking for help like more then 45 days.

Sent from my u8800 using xda premium

I do the same as to update without using battery but still it doesnot update !
Any ways i will try again without holding power ...........
my problem is my phone doesnt get updated with any rom even the stock 2.2.1. and just keep it into boot loop at android animated logo screen.
Well Maksimitoisto, i cannot claim on my warranty as it is already out and sencondly befor i can put efforts and take pain of paying for another phone or replacement, i want to try max what we can do on it to solve the issue.
since the phone can boot into the Pink and blue screen and also the normal way (with boot loop) i belive its not more then a software problem, the only thing is i need to get the right to overwrite it.
Any help please write.
Appreciate everyonce solutions & support.

Pink screen, Blue screen and update failed

Please help ...
I know things like this are asked many many times, but I couldn't find a way to get it working :-(
I've got a Huawei u8800+ from merimobiles yesterday. The first time I tried to get into recovery mode the phone was going for a firmware update and got stuck at step 1/2 "update failed", so I had to pull out the battery. So from ths point on, everytime I boot my phone (without an sd card) it keeps on updating (and failing). So I tried to get the pink screen and connected the phone to my pc. I then accidentally formatted the image dir on the phone instead of the sd card
Here are the problems I'm facing
1. Without an sd card the phone always tries to update.
2. With a sd card and a dload folder I get a blue screen (normal boot, boot with volume +)
3. With a sd card and volume + and - I get the pink screen. So I can still access the phone ... but I have no idea what to do next.
It looks like somehow it doesn't matter what's on the sd card ... it just won't update what's on it (tried several sd cards .... all FAT 32 and a dload with an UPDATE.app in it)
I've already created a image dir with recovery.img boot.img etc ... but without any luck ...
So...is it still possible to flash any firmware?And ... does anybody know which kind of firmware version comes with a Huawei u8800+ from Mermobiles (I haven't heard from them yet).
If someone would be so kind to post the image dir somewhere that would be highly appreciated
Many many thanks in adance
Regards
Oh and by the way ... when you put a dload folder with an UPDATE.app on your sd card and you press the power on with volume + and - , you shouldn't see a pink screen but the update should start automatically?
Still no luck with finding an answe to my problem
I really hope someone could help me out.
No, if the update found on sd card, you will not see the pink screen. The update will start automatic.
Try to power off the device, remove the battery and connect it with usb cable on pc. Then press the combintation of power,vol+, vol- buttons.
Thank you for the reply ... I've alreaady tried to pull out the battery and connect it to the PC, but with volume + and - it gives me the same pink screen :-( and without pressing the volume + and - it gives me a blue screen :-(
Finally got CWM to work so I can flash roms .... but with every rom (tried 2 roms) the phone just crashes (no reboot .... a real crash) ... what can be the case?
Can it be because the kernels?
Thanks in advance

helppppppp
My Pro Plus has started doing the same since mid-April.
So far, I've tried removing some apps but nothing has been effective in locating the source of the problem.
Logcat hasn't given me much help.. fatal errors seem to happen with no single app/process.
It'll reboot probably a maximum of 4 times over.. once which gives no phone reception before settling.
So far, I've found that the phone behaves itself with the SD card removed.
I've tried reformatting the SD card before copying all my files back over to it.
I've tried rebuilding the Android folder on the SD card.
My next step is to try moving my files to a completely different MicroSD.
It might be a few days until I can get hold of one to try.
I have about 5GB free on my 16GB card.. I'm wondering if there's a limit to how much data sitting on a card that Gingerbread can take.
I have a rooted phone.

L7 HardBricked + bricked sd?

Hello there!
I have already used the search function, but I wasn't able to find my exact problem in any other post.
Yesterday I flashed the rom Carbon (4.4.2 maded by coderzs) on my p705, and today It appeared with the LG logo a little buggy, then I take out the battery and it never turns on again (no matter what key combination I used) and another surprise is that my 32gb micro sd was corrupted too, I can't even format it with HP disk storage format tool, neither I can use Recuva to get the files.
Plus, when I connect the phone to USB withouth battery it gets really hot.
Do anyone have an Idea of what to do? Actually I'm more concerned in recovering the SD card info or at least use it again in the future.
Thanks in advance.
New Info:
Now I can make it boot LG logo sometimes, but it still buggy and there is no key method to enter bootload emergency is working. =S
try this

1 try putting it in a blackberry while its on (old bb are the best) and it will prompt its corrupted say yes to format and then try plugging into recuva (worked for me numerous times)
2 did you try vol+ and vol- and power hold and release power after vibration and then use KDZ_FW_UPD_EN.7z
try link2sd it does same but on a different level

I will have to try to put the sd in another phone, but I don't know anyone with bb =S
Also, the only way to make the phone "boot" is holding vol+ (and any other key) and then it vibrates and sow a buggy LG logo, then it continously restart over and over again showing different buggy logos (LG ones).
THanks for the reply.
Other than trying kdz flash you can use LG official update tool to do an emergency update. You will in that process need to enter both imei&serial. Basically this also flash kdz but in addition it check and repair your partitions.
Hope it might help you :beer:
I will try that last advice, thanks
The SD card seems dead =S
It is recognized by the computer and devices, it shows 1gb instead of 32 and it needs to be formated, but no program let me do it.
I already have this problem with my girlfriend's phone last week-end and solve it!
I use a modified stock rom (root + cwm in KDZ) avaiable here http://forum.xda-developers.com/showthread.php?t=2214717. ROM KDZ V20A_00 ROOT
Put the phone in emergency mode (power off the phone, plug it on usb to your pc, wait for the battery logo then press vol+ and power)
Start KDZ updater then flash the rom. After install, start cwm (vol+ vol- power home at same time) and do a wipe data factory reset and wipe dalvik and cache.
Reboot and it work! :victory:
Yes, I already did it too in the past, I bricked my phone twice, but this time is a hard brick, and wont let me get to emergency mode (there is no way, really I test it). It seems that I can't make it boot =S
Maybe all this is because I was using ART instead of davlink, and something may explode inside the phone.
Thanks anyway for the reply, I'l keep searching for some solution (the SD have more chances to keep alive I guess)
hmmm

does your phone come-up with blank (black but backlit) screen ?
if it does then you will be able to use kdz updater in attachment LG-RDTT_1.0.5.4 (needs included windows enabler for this version)
use THIS GUIDE to flash just skip the hosts file editing steps
and let us know
Okey, I'll try it in a moment
well, it didn't work =S
Computer don't recognize the phone, I tried with ubuntu, 3 windows and 2 mac.
When you say buggy logo do you mean there is visual distortion to screen?
if so it most likely will be hw damage
you got ubuntu can you see it in adb ?
Push/pull ?

No, and I'm not able to mount it neither.
The logo is as you say, but it reboots constantly and make some little color bars blur the image, then restart again and make some other kind of buggy image :x all with LG logo.
--------------------------------------------------------------
Well, I finally choose to go for LG service, I'm going to call them tomorrow.
Thanks for the help and trying to solve my problem, I guess they will make my phone boot, but my SD will never come back, or that is what is seems =(
It keeps saying that it is read only, and that's why I can format it.
