Lg L90 stuck on fastboot "loading" please help - LG Optimus L90

when I did it go into bootloader but it could not go into download mode, i know how to restore back to stock rom unroot. i rooted it using towelroot then flashed wrong recovery but recovery worked, it was on 6.0.0.0 something. When I try to go into fastboot and it say "loading" top of screen and tap volume up to continue, nothing moving foward into download mode.
Please Help.

Pull battery? Enter recovery (or flash new recovery.img in fastboot). If this doesn't help, try kdz.

I will try it when I get home, already did battery pull, that did not do it. So I was thinking doing lg tool to update firmware then downgrade later.
Where do I can find this recovery IMG? Custom recovery or stock recovery?
Thanks for replying.

Custom : see thread from cm11, @Quarx, twrp or cwm. @shoxxy has latest twrp

When making this kind of post, ALWAYS include the device model you are speaking of. There are 4 different models of the LG L90. From your location, I'll guess that you have the LG-D415 model.
From what I'm reading, you are NOT in fastboot mode but Software Update Mode. You MUST zero out the LAF partition in order to enable fastboot on the device. Also, fastboot and download modes are one in the same.
And what exactly are you trying to do? If your recovery is your issue, you can go here and scroll down to post #4 and download a flashable version of TWRP which can be flashed with the recovery you already have. Once flashed, find an option in your current recovery to "Reboot Recovery". It's probably in the "Advanced" menu. This will unload the current recovery from memory and load and execute the new recovery.
You also may want to have a look at the Frequently Asked Questions - LG Optimus L90 thread.

Well I messed up big time, no os installed, But device stills works were able to see download mode with numbers beside left screen not on second screen with bars.
Able to go in Twrp but it keep saying failed when i flash stock rom (remounting problem?).
Device I battery pull and put battery in and able to see LG logo then it went into CWM recovery itself then I selected Recovery reboot from CWM leaded me to TWRP recovery.
Tried to flash using lgtool2014 but flashing stock rom bars hasn't moved kept saying replug usb and retry.

Good News! I got it to work again!
Searching many website homework endless hours and I got my phone to work again. I was not panic I had nexus 6 with me, so I had a experience previous devices rooting.
Anyway, I went through to unlock bootloader and then I reboot the phone into TWRP recovery and flashed stock.zip sucessfully, unmounting was failed. Clicked reboot phone and LG logo appears stayed for like few sec then starting seeing tmobile boot up and everything seem well. gonna root again to see if i get any of this to work.

How do you use clockworkmod rom manager?

I have a Mytouch 3G running test 7 on my phone, and i just installed the clockworkmod rom manger. After, installed it i wanted to flash a new rom, so flashed the clockwork mod recovery, and when i tried to install the new rom from the sd card, it keeps on getting stuck on the mytouch screen, and nothing happens. How do i get into the recovery screen? thanks
First: This belongs in Q & A !!!!111
Which ROM did you flash? Maybe you had to wipe before
right now, i'm running cyanogen test-7, but when i go into the clockworkmod rom manger app and pick the flash rom from sd card, it just says it has to go to the recovery, and then my phone will reset and it would just get stuck on the mytouch screen. So, i just pull out the battery and reset the phone again, and i realized if i press the end button, it will go the rom that is already on the phone. I'm i suppose to push some buttons or something to get to the recovery screen?
No it should flash the rom you select and reboot the phone to boot the new rom without keypress needed.
maybe the wrong device was selected when downloading the recovery image? Try reinstalling clockworkmod recovery from rom manager.
Mod edit: not dev related, moved to q&a
I have the same problem.
I downloaded and installed Rom Manager from the Market and it has completely screwed up my recovery (I can't get into it at all). I tried flashing Amon's again (through Rom Manager) and it still doesn't work.
HTC G1. CM5.07 test 7 (trying to go to stable!).
Your recovery has been corrupted, you will need to flash it through fastboot.

Connect to your PC via USB, and from the command line issue "fastboot erase recovery" and then "fastboot flash recovery filename.img"
More on common fastboot commands here can be found on these forums, i'm not allowed to post links.
i connected my phone to my computer but nothing on my computer pops up. only the new hardware wizzard pops up. what do i do from here? im i suppose to get a adb popup? how do i set up the fast boot? i'm so confused..thanks
some one, please help..i want to be able to flash new roms in the future...thanks in advance
Can I sugges that you try this sticky thread at the top of this forum board.
It contains all you need to know on who to set up fastboot and how to use it - there are a couple of tutorials on it if you read through the thread.
CM 5.0.7 for Dream/Sapphire introduced a bug in flash_image. It causes recovery flashes to fail. It has since been fixed in the latest test of 5.0.8 I believe.
Man i have the same darn bug cant get back into recovery for nothing, and i dont have a pc to fastboot i have a non intel based mac so no adb or fastbooting, i have been doing fine for forever without adb or fastboot but is there any way around this one, i need help bad, im on HTTClay Superbadv1.3 and it has all sorts of bugs but i cant nandroid or bart or flash any rom without recovery, can someone please help!!!
Also is there another way to erase the recovery partition?

bootup problem

attempted root and used superboot grj22 from modoco pphone is unlocked and after double clicking on indows bat file as directed phone is locked on boot x
this phone has just come back from htc with a new power switch installed and 2.3.4.
anyway could use some help daughter is upset I locked her phone.
can get to boot menu however can not get into recovery. I get a triangle with exclamation in it
thanks
Please read the Wiki, Rooting guide for unlocked bootloader.
Flash recovery through fastboot.
Flash whatever ROM you want from recovery.
You've flashed a wrong kernel (which is contained in "superboot"), that's why you can't boot.
another question
read wiki and followed instructions which said after loading passimg that this was an older version. searched more and found another thread that gave a new file that was supposed to load the older version of the rom and get around the error "older version"
still not working any other ideas will be appreciated
Just to make sure I understand right you tried the frg83 passimg file and you got "main version is older" error? If so then can I just ask you is your bootloader unlocked (at the X screen before the cyanogen mod logo do you see an unlocked padlock)?
hi
yes padlock on screen is unlocked tryed to flash again and get the same error version is older
thanks for trying to help kid leaves for school tonight and is freaking
more
also askes if I want to reboot device
It'll be long fixed by then don't worry
Boot into bootloader then from there select the recovery option. Once there tell me what you see if you see and android with a /!\ next to it then press power and vol+ power slightly before. Then you will get a menu select power down. If you go straight to the menu tell me what color the writing is.
hi
get the triangle white with a orange exclamation in it
Ok then you'll need to flash a recovery via fastboot. So since you bootloader is unlocked I assume you already have the SDK set up and the drivers installed if not then I can help you with that too, but now just download this file and place it in the same directory as fastboot on the computer and download this file and put it on the root of your sd card (not in any folders).
Then boot the phone into fastboot (hold down the trackball while powering up) then connect the phone to the computer via usb and open a command prompt in the directory where you have fastboot. Then input these commands:
fastboot devices (this should return the s/n number from your phone)
fastboot flash recovery recovery.img (where recovery.img is the name of the first file you downloaded earlier)
fastboot boot recovery.img (same thing here)
The phone should then boot into recovery from there use the trackball to navigate go to flash zip from sd card then chose zip and chose the second file you downloaded earlier (the one you put on the sd card), after that wait for it to flash then press vol- to go back to the recovery main menu then select reboot system now and your all good you have stock with root access, if you want to flash a custom ROM then just ask I can explain that too.
As I've said, follow the guide FOR UNLOCKED BOOTLOADER.
You didn't.
The guide for unlocked bootloader is in Unroot/Restore section, called "using fastboot".
Actually, the only thing you need to do is to install recovery. Go to "recovery" guide - again, FOR UNLOCKED BOOTLOADER - and install Amon_Ra's recovery.
Once you have it, you can flash whatever you want, including stock ROM.
ok
everything is good except that i tryed to flash downloaded zip from sd and got error that zip is signed wrong also zip verifacation failed
again thanks excited I got this far.
so after this gets fixed than will phone reboot and go to 2.3.4 that was on there before?
will I be good to go for a new rom and last but least like the miuis and recommendations from an expert?
funny I bought the sensation and forgot how to do all this probably the pressure of the child (oh my god you wrecked my phone) Forgetting of course it was dads to begin with DARN KIDS
me dumb as a box of rocks toggled zip verifacation and ra unzipped.
afraid to push any buttons.
should I reboot?
and then Its ok to load a rom?
thanks
radio should be ok as it was just loaded from htc?
Ya you should be good don't worry you can't brick it by flashing something to the system partition only to the recovery and hboot partitions. Just select reboot system now and all should work fine.
Sorry for the late response I was away from my computer
still stuck on nexus x screen ??
earlier someone posted that when I used superbot I got the wrong kernel?
not sure but still stuck
just tryed to boot into recovery and it wouldnt go
Oh right sorry forgot an important step you kind of need a ROM my bad ok so forget about su you're going to need to flash a ROM I suggest cyanogen mod as a first ROM but it's up to you if you want miui or something then go for it. Here's a link to cm7 http://dl.dropbox.com/u/31690913/android%20files/update-cm-7.0.3-N1-signed.zip
So to flash this simply boot into recovery then go to wipe, wipe all at least 2X I do 5X to make sure then just go to flash zip from sd card and flash the ROM.
In that case do like we did last time and reflash it through fastboot. Now sorry but I gotta go maybe someone else can come and help you if not I'll be back later tonight.
thanks
thank you so much for helping me with this got everything working including the new miui rom.
when you panic just a little you forget all the things you knew how to do before.
thanks again.

[Q] Soft/Hard Bricked, Lost Root, Lost Recovery, USB Not Recognized

Hi all, this is a last ditched effort at maybe saving my phone. I did an update on my SU and for some unknown reason it rebooted my phone. It then loaded up my rom until the kernel settings loaded then rebooted once again. I then tried to go into recovery to flash a backup and it booted me straight into my unlocked fastboot. I then tried to reboot once again in hopes I could fast navigate into twrp through rom manager, once in I was prompted that I no longer had root. I then decided to start over from scratch and load a recovery in fastboot. Once I had everything good to go I plugged everything in and instead of recognizing my phone as a drive, HTC manager popped up instead. I then updated my drivers to see if maybe that would fix the problem with no luck. I am at a loss at this point. I would greatly appreciate any help you guys can offer.

This is completely normal, you should have just rebooted the phone and been done I then tried to go into recovery to flash a backup and it booted me straight into my unlocked fastboot. Again totally normal, thats the bootloader use the vol to move down and choose recovery and hit power this will boot you to TWRP I then tried to reboot once again in hopes I could fast navigate into twrp through rom manager, once in I was prompted that I no longer had root. I then decided to start over from scratch and load a recovery in fastboot. Why ? Once I had everything good to go I plugged everything in and instead of recognizing my phone as a drive, HTC manager popped up instead. You should not have Sync installed only the drivers I then updated my drivers to see if maybe that would fix the problem with no luck. I am at a loss at this point.

I was doing a SU update. It restarted into a loop that boots about 1 min after the splash screen then resets. I've tried to redownload root through SU app as I can no longer connect through usb but it reboots to soon. I used Rom Manager to try and get into recovery as a second alternative.

Reboot to bootloader / fastboot USB
and from command line on pc
fastboot erase cache
fastboot reboot
I cant understand why people using those ROm manager apps to install stuff. And you said it rebooted after you update your SU. Then i tink you pressed reboot into recovery instead of NORMAL. Am i wrong?

I no longer have a recovery to be able to flash anything. When I try to load into recovery it just boots right back into fastboot. I was just using rom manager to boot into recovery after I couldn't get into recovery through fastboot, not to flash anything. I was updating Super Su through the actual app itself. it seemed to be downloading something when it rebooted itself and I lost root, recovery and the ability to connect to my computer.

I have updated SuperSU many times and never got any problem so there is something you did. Are you on custom or stock rom?
Are you s-off / unlocked bootloader?

My bootloader is unlocked and i'm running Viperrom. I've never gone through the process of s-off but for some reason it says it at the top of my fastboot screen...not sure if that's normal or not.

Ok. I think you need to reflash recovery again.
Boot into bootloader and fastboot usb
then download TWRP recovery from here http://techerrata.com/browse/twrp2/m7 and pick 2.6.3.3-m7.img
put it into your fastboot folder and flash it "fastboot flash recovery openrecovery-twrp-2.6.3.3-m7.img and hit enter
now try to reboot into recovery. When there Wipe Dalvik and Cache and reboot. If recovery ask you to root your device then accept it and reboot.
Remember to connect phone to right USB port not 3.0. Use 2.0 port and try annother cable also.

I've tried a few different cords and all 3 ports I have still nothing but the HTC manager thing. It will recognize it but only for a split second while booting up but it says HTC BUTTERFLY as the drive and i'm not sure if that's a problem or not but it won't recognize it at all through fastboot.
you cant boot up. if it doesnt recognize it in bootloader mode then i dont know.
Try restart PC. Maybe you have several adb at same time. Adn uninstall htc sync if not but keep drivers

I hadthe same problem after flashing a kernel. I repeatedly tried the bootloader (audiodown key + power button) until it started. Recovery was not available, in the red triangle screen press audio up key,got the system recovery screen, wipe cache, reboot the system and then try installing Twrp recovery. It worked.

I think @jpaulpra was telling him to reflash stock recovery
then boot to it and do clear cache.. then reflash twrp
When I got into bootloader, I lost the Twrp recovery. So when I selected recovery I got the screen with a "triangle and exclamation mark". If you leave it will reboot the system after couple of minutes. But if the audio up key is pressed, it will show a system recovery screen, where cache can be wiped

Basically all I'm trying to do now it's find a way to get my computer to recognize my phone as a drive. When I go into viper settings and go to advance menu (with the short time I have before boot loop) there is an option to mount drive. When I select the option to do so it hands on splash screen and I have to hold power button to recycle back on. Once back in it's no longer selected. I've never seen a boot loop go pay the flash screen. Is this normal?
Pretty SOL with my son's Nabi2

[Q] Stuck in bootloop after attempted upgrade

I just recently got my TF701T. I unlocked the boot loader with the Asus unlock tool and then attempted to upgrade to version 11.4.1.17 so that I could install Cromi-X 7 on it. I placed the file UL-K00C-US-11.4.1.17-user.zip on the root of the tablet and rebooted. Once the OS booted back up I was alerted that an update file had been found and I clicked it to begin installing.
The tablet rebooted and appeared to be upgrading but now all I see is a robot on his back with a red exclamation point. After a while the tablet will reboot and again show the Asus splash screen and then the upgrading robot then immediately go to the robot on its back.
I can get to fastboot by pressing power and volume down. I see "the device is unlocked" at the top of the Asus splash screen then I see a screen with the following. Android macallan-user bootloader (1.00 e) released by "US_epad-10.14.1.47-20131022" Choosing RCK, Android or Wipe Data do nothing to help the situation.
I thought I had found a solution in this thread http://forum.xda-developers.com/showpost.php?p=47933481&postcount=1 but the link for drgravy's recovery.img is not working.
I would appreciate any help recovering this tablet. Thank you.

Do you have the Asus drivers and adb/fastboot installed on your PC?
If you have fastboot access, it would be as easy as:
Download CWM 6.0.4.7 from here http://droidbasement.com/db-blog/?p=3207
I know it says you have to be on 10.26.1.18 for this, but since you will use it only to flash the latest bootloader, you should be fine.
Put the recovery.img into your fastboot folder and flash it (if you need help here, let me know).
Then fastboot reboot
Your tablet should boot up normally now
Part 2:
Head here http://forum.xda-developers.com/transformer-tf701/development/rom-nov-24-t2951032 and grab the 11.4.1.27 bootloader/CWM 6.0.5.1 package
Flash it in your existing CWM
Reboot
Part 3:
Boot to recovery
Make a nandroid of your stock rom
Go back to home
Wipe data, cache and Dalvik
Flash the rom (which you have loaded onto your microSD)
All done.
Don't forget to delete the (probably corrupted) firmware file
EDIT: BTW, when you reboot to system from CWM you will always get the question if you want to fix root. Choose NO - it's a bug....

Thanks for the reply. I do have the drivers and adb/fastboot setup on PC.
After I could not find anywhere to download the version of CWM that was supposed to be for my firmware version I was afraid to proceed.
When I get home I will try the steps you have listed above and report back how it turned out.
One question, In part one after I flash recovery CWM 6.0.4.7 do I reboot to recovery or let the tablet reboot to the OS?

Shouldn't matter. When you flash recovery or bootloader, you flash it to the staging partition. The actual installation happens during the next boot - you'll see a brief blue progress bar under the Asus logo.
Booting a recovery for the first time I always reboot to system after the flash, then power down and enter the new recovery from the bootloader. Probably booting straight to recovery or bootloader is ok, but I have not tested it.

Well it has gotten worse and I think I have lost fastboot now. I downloaded the CWM from part 1 above and flashed it in fastboot. I typed fastboot reboot and now I am stuck in a bootloop still. It says "The device is unlocked" at top of Asus splash screen for about 15 seconds, screen turns black and the goes back to Asus splash screen.
I tried holding power and volume key to get back to fastboot but no luck. Any ideas?
Wow! You are really having some bad luck there!!
First the failed firmware update and now this.... Please post the commands you used to flash CWM.
I have no explanantion for this since you did not even boot into CWM.......
Unless..... the bad firmware flash left a command behind calling the stock recovery to do something (which in your case did not work anyway since it just looped) and now the bootloader tries to execute the command which is not "understood" by CWM. But that still does not explain why you cannot boot into the BL anymore......
Can you turn it off by long pressing power? Try every which way to get into fastboot. Without it there is not much you can do I'm afraid.
Try the restart pin hole (I believe it's on the left side of the tablet near the top) in conjunction with Volume Down, try leaving it alone for a while, try timing the button press somewhat differently - anything to get you into the BL again...
I feel very sorry for you, mate!!
Thanks for helping even if it didnt turn out great.
I typed fastboot flash recovery recovery.img after I had downloaded 6.0.4.5 and put it in my fastboot folder. I got confirmation that it transferred successfully.
Then fastboot reboot The tablet rebooted but still would not boot into OS. It still boot looped but did not show the dead android icon anymore.
I got back into fastboot and selected RCK but it would not boot into recovery. Finally I got back into fastboot and selected wipe data and that is what got me to current situation. Now the only thing I get is when I long press power and volume up my PC picks up an unknown device that says apx.

I don't know what happened before - maybe you were doomed since the bad firmware flash - but that last step sealed the coffin.
Using Wipe Data from the bootloader with a custom recovery installed is asking for trouble. Never ever do that.... Sorry, it's a brick. [emoji24]

Can't enter recovery mode???

I can't seem to figure out how to enter into recovery mode on my T-Mobile G4. It's running everything completely stock. I have tried holding power button and volume up until the logo comes on and releasing both buttons and then immediately holding them both down again waiting.. and nothing happens. I've even tried waiting for one second after I initially release to hold them down again. Same outcome. It always just boots back up into Android. I have tried volume down instead.. Nothing. Can someone please show me how to boot into recovery mode? Again, running stock rom.
I had the same issue. This is what I did to resolve it.
1. Enable Developer Options (see here).
2. root the phone (see here).
3. Download TWRP for the LG G4 H811 from here.
4. Install Flashify from the Play store.
5. Open Flashify and select Recovery Image -> Choose file and select the file from Step 2 to install TWRP
6. Reboot to TWRP from Flashify
When I was on the factory ROM I had to repeat steps 5 & 6 any time I wanted to boot into recovery (TWRP). None of the other boot options worked for me. Not button combinations and not even using adb (adb reboot bootloader). So what I did next is I decided to try another ROM. I installed one of the CM12.1 nightlies. Now running on CM12.1 I can boot into recovery without issue. I have no idea what is in the stock ROM that made it impossible to boot to recovery. I haven't been very motivated to go back to the stock ROM to do any further troubleshooting.

So, you're saying that there is no other way to get into recovery, but to root the phone first? I was hoping I didn't have to do that.. I haven't researched how to properly save the stock rom in case I need to get back to it because I need to bring it to the store for some reason or another..

If there is a way I didn't find one. There very well may be a way to do this. I just didn't put in more than a couple of hours of effort.
That's not what I'm talking about. That's talking about factory resetting your phone with the hardware keys. I'm talking about entering recovery mode (kinda like the bios of the phone) using the hardware keys.. It's different.

I'm starting to think T-Mobile did something different with their variant to disable people from entering recovery mode.. This is irritating. I'd like to have the option of doing so in case I need to re-calibrate my battery or anything else that I'd need access to the recovery for.

I have been trying a few different ROMs over the last few days. The modified stock ROM (Genisys) is pretty much the same as the stock minus some bloatware and it is rooted. I have no issue booting into recovery from it. Maybe that is worth a try for you?

Alright.. I guess, I'll have to try that, but first is there any way to do a backup of some sort in case I have to go back to stock rom rooted? I got my G4 about a month ago and haven't done much research on rooting this specific device. I haven't had a high end phone with rooting and rom options in a long time. The last phone I had a chance to root and install cool custom roms on was a Samsung Galaxy S2. If you can guide me in the right direction I'd appreciate it. I guess I have to start from square one again. In the past I remember that in order to go back to completely stock you had to have a usb jib to reset the flash counter. Is it the same for this case? I welcome anyone's helpful input. Thanks, everyone.
