Hello everybody, I have a optimus zone that I am trying to fix. When I first aquired it it was stuck in a boot loop. Was able to put it in download mode and after finding about 5 or so drivers (seperately) i was able for lg support tool to put an upgrade on the phone. When it was done it was still in boot loop. I set the phone aside for a few days and when i came back to it it was not in boot loop and went to the activation screen on the phone, but before i could do anythin the phone force closed process after process after process includes the launcher that runs the phone. So i did another firmware upgrade to the phone and it is now stuck in boot loop again but this time it is not fixing it self. I cannot get into recovery mode like it doesnt have one, since the beginning i was unable to get recovery mode. What i am looking for is any help and where i can find recovery"s for the phone and the phone"s stock rom files. I have looked everywhere and for the life of me i can not find any recovery modes or stock roms for this phone!

Hello
I have been using my int Gs3 for sometime and decided to root and explore the mods and custom fw world. I have started with getting to root access and after that install CWM.
Then I try to install nightly cyanogenmod 10. It didnt work and boot back to normal GS3 Touchwiz interface. After that I tried the GooManager and when the phone is restarted it went to bootloop. I removed the battery and put it back. The problem started there.
The phone does not boot to any OS, I only can see the galaxy s3 9300 black splash screen and awatis there. I can go into download mode, but when I go into recovery mode, I can see the Android robot, and it dies The screen is too fast but what I can see it cannot mount EFS, System and any folder.
So I have tried several different methods
- Tried to flash with original rom, different roms, CWM and what I can find suitable for international model. But everytime I got stucked in Nand Write part. In some of them, the flash started and stucked in installing some parts(passes the cache and hidden and stuck after that)
- Tried with bricked phone roms, different PIT files and Bootloader Vralec methods.
- When I am trying these, I have tried with 3 different PC's with/without KIES and Samsung drivers installed. When I plug the phone in Download mode, the PC recognizes it as Generic device.
- I manage to flash the CWM but when it restarts it does not go any further than the first splash screen, but in Odin, some time later it turns to pass. Funny, when the phone is on Galasy S3 black splash screen, the pc recognizes the phone and starts to install the driver.
So, here is an interesting flashing story of mine. I really would appreciate your valuable comments and suggestions.
Thanks in advance.

I apologize if this is in the wrong place, and I've really tried searching around, but nothing seems to work/ is tailored to the m8.
So, I just got an M8 new out of the box, rooted it and successfully installed cyanogenmod. Problem is, I was playing around with it, trying to get the GApp store and somehow (did what i think was) deleted my roms completely. Now upon booting up the phone I just get the "This build is for dev..." screen, and with the volume down+Power button to access recovery mode I constantly get put back to the fastboot screen. I tried flashing a custom recovery as in "Phone arena CWM flash recovery" guide, but no luck because my computer is reading the device as offline. I honestly have no idea what to do, and if anyone could help me I would be so greatful...
TL;DR: Stuck on boot screen, can't enter recovery mode, think i deleted all my roms, help please
On a scale of 1 - bricked, how bricked is my phone?
HUGE DEVELOPMENTS, GUYS! I've been able to access recovery mode again by re-flashing ClockWorkMod.

On that scale, you are zero. If the screen comes on, you aren't bricked.
Hi, today I tried to downgrade my Galaxy S3 from Cyanogen 12 to stock firmware (So from Lollipop to Jellybean) but now it's stuck on the bootsceen and I can't access the recovery mode, I can just access download mode.
Hi Hencick - Welcome to XDA.
I'll just naturally assume that you're familiar with flashing roms...
Were you running a custom kernel with CM?
Can you access adb functions with a pc?
I have a similar problem on my phone I discovered today. I just get the Samsung logo on screen, it goes off, then comes back (bootloader loop i guess).
It was just sitting on charge. It hasn't done anything for a while other than updates, now when I come to it, it's like this.
I can't get into recovery mode, adb mode, download mode or anything. Just the Samsung logo flashing up, then going and coming back up.
Is this recoverable?
As it it keeps powering up, then off, then back up I'm not even sure I can use Odin on it.
TIA.
Edit: Ok, I can get it into download mode it seems. Only, now I'm not sure what to do! lol
Hello everyone,
Even though this is my very first post here, I've been occupied with rooting android phones and flashing new ROMs quite often. I encountered what seems to be an unsolvable problem.
I'm using an S3 I9300 with ArchiDroid v3.1.5 flashed. I had to remove the power button several months ago due to malfunctioning. A couple days ago, my phone suddenly went into a boot loop after the battery was drained and phone was shut down. I charged the phone and turned it on but it never boots. Samsung logo comes and archidroid boot animation starts but the phone gets stuck there. I actually know many ways to get out of a boot loop using download mode, recovery mode, adb, fastboot etc. However, it seems like there's no way to get my phone out of this loop since it does not have a power button. I've tried every single method to go into recovery or download mode without a power button but it does not work. Since the phone does not boot, I can't use any apps to go into download or recovery mode. I tried using adb while the phone is stuck at boot animation but it is a no go due to authorization. It looks like there is no way to get this phone into either download or recovery mode where I can save it easily.
I've been searching everywhere for the last two days for a solution and any method I found, I tried immediately but nothing works. I tried all common and even uncommon methods to put the phone into download mode without a power button. Also couldn't find a way to get around the authorization problem to use adb.
My phone is now out of order and I need a solution urgently. Any help will be appreciated. Thanks in advance.
I had flashed a custom ROM on my phone maybe a few months or a year back. I think I remember trying to reflash it trying to fix some bugs but it ended up getting stuck in a boot loop. I think after several tries it booted into TWRP recovery and I had factory reset it (these details might be a little fuzzy as I tried all of this months ago just never got around to posting this since I needed to focus on schooling) but now when I try to boot it, it just boots to the LG logo screen and gets stuck. I can boot into S/W upgrade mode and I had tried to restore it using the LG support tool but it recognizes it as the latest version and will not reset the phone. So right now I am at a loss and need some help to restore the phone and to hopefully flash it again. Thank you!
