[Q] Bootloop hell

I apologize in advance if this same issue has been replied to elsewhere. I'm in kind of a unique situation and couldn't find an answer anywhere.
I'm got an N1 with 2.3.6 stock ROM, rooted. Recently I downloaded Titanium Backup PRO and while attempting to integrate dalvik cache to ROM, my phone rebooted into a bootloop. I'm assuming this is a bootloop. I get the colorful splash screen, it freezes for a second of two, then continues on, and on, and on....
Is there a way to get me out of this loopwithout having to wipe all my data, so I can backup all my stuff before I flash a custom ROM?
Everything I see about bootloops, mentions unlocking the bootloader and wiping all your data. I've seen downgrading using PASSIMG and loading stock rom. I'd really just like a simple way to get out of this loop hell and get my phone back up. It's in teh ship now getting it's power button fixed.
Thanks in advance

first thing i do on bootloops is pull battery
if no go pull battery and then pwr on by pressing pwr and trackball at same time--you can then get to recovery and maybe wipe dalvik and cache and reboot
i have never used TB for anything other than backup/restores, so can't help with dalvik integration

You might be able to fix it by wiping your cache from recovery.

Thanks for the advice! I'll give it a try as soon as I get my phone back from being fixed.

Hey guys, I hope you can help. I got my phone back with new power button, Yay! When I try to boot into recovery, teh Nexus X logo comes on for a moment and then I get a white triangle with an orange exclamation point. Do I need to use ADB to try and go to recovery and wipe my cache? I've never installed a recovery image. Do I need to do that or should there be a stock image already on my phone? Am I SOL?

One more thing that might help. I notice that when I go into HBOOT, the phone searching for 4 images from my SD card and can't find them. They go by too fast to write them all down but I think some are PASSIMG, PASSDIAG, etc. Again, do I need to load a recovery like clockworkmod on my phone first and then go into recovery to attempt to wipe my cache?

I get the same passimg all the time--no problem
If your phone came back from repair, you are probably unrooted and hence the triangle. At least that is the way I remember it, but has been two years since I rooted
If that is comfirmed by someone else, you wil need to reroot and install a recovery
A good time, if you haven't, to install android sdk and root/install recovery the right way and have full adb/fastboot features
there other ways I am not familiar with
does the lock show unlocked on the screen, they could have relocked bootloader
the wiki has the instructions, just have to navigate to the htc smartphones and N1

jus to make sure that if u still got root. install su checker app from play store and confirm.
if not root using SUPER ONE CLICK ROOT.
flash recovery (4EXT is good) www.4ext.net
do a backup and then flash the rom u want

Thanks I'll check. I only had teh power button fixed and not by HTC so I doubt they unrooted it. I'm still in a bootloop but I can use superoneclick still, so I'll give that a try.

so what I'm trying to do is wipe my cache without wiping my data. I don't think my bootloader is unlocked. Am I screwed?I'm in a bootloop, so I can 't install anything to the phone. I probably could put a recovery image on the SD card, but if my bootloader is locked, I'm guessing that won't work. I'm rooted. When I go to HBOOT, the phone looks for passim files and doesn't find them, then when I choose recovery I get the white triangle. I've try to flash a recovery image through ADB but I get an error, failed to load image. Again, is that a bootloader issue?
I'm almost at the point of just wiping my data and hoping I can get it all back somehow.

You really know nothing huh. The triangle is the recovery. Press power button and volume up at the same time, it will the show you some options like wipe cache.

Did you miss the "stuck in boot loop" part?

sorry,
meant that the triangle is your stock recovery--
you install recovery thru fastboot not adb
i would still, if you haven't, install android sdk on pc-unlock bootloader (fastboot oem unlock) and fastboot recovery--all in wiki
i think it was mentioned--holding down pwr and tb will get you into fastboot mode--phone connected and usb debugging selected on phone
you'll just have more flexibility with flashing roms etc and getting out of trouble

Little Help Returning to stock

Think I managed to mess my system up a bit. I can get into clockwork but when I flash any roms it seems to freeze up. Can someone point me in the direction to flash back to stock from clockwork so I can start completely over. Ive been looking around but cant seem to find the files and guide. Thanks

Seems like you lost root..
- Flash a pre rooted GB ROM from THIS thread, let's say LC1
- Go to the 4th post of ChainFire's thread and get the CF Root kernel for it (so you can have CWM + root) and flash it using the "always rooted.bat" method described in 2nd post
This way you'll have LC1 ROM with root and CWM recovery installed

Damn Im still stuck. Tried flashing a couple suggestions but odin fails. Anyone willing to walk me through a full restore to stock? Would be greatly appreciated!

Think I got lucky and figured it out. Hard a hard time finding the stock rom but got it done. Phone is updating as i type this.

You didn't actually post how you fixed your problem.
I ran into problems when reverting to stock GB from custom ICS. Flashing with Odin went fine but I got stuck in a boot loop.
I eventually managed to sort it by holding vol up, power and home buttons on boot to go into stock recovery mode, then did a wipe / factory default reset. When I rebooted it all fired up fine.
Just posting in case it helps anyone else.

If you get stuck at boot animation after flashing a stock Rom, just do a simple factory reset from stock recovery, that is all that is needed.

[Q] CWM Recovery doesn't let me get past first 2 options

Hey! Would like some help from you guys if possible.
Yesterday i tried to install the Marvel ROM on my P970, doing a step by step and it went ok but i ended up not liking the ROM so when i went into CWM Recovery to wipe data/factory reset etc to install another ROM, CWM Recovery just wouldn't allow me to reach those options, everytime i tried to press past the 2nd option the screen kept resetting back. I tried with touch and options went in but i didn't have any lines saying "YES" to erase, all said "No"..
So at first i tried to SmartFlash the phone back to the original Froyo version, and the phone got bricked; after that i tried to SmartFlash it with a Gingerbread version and it actually worked but when it resets the phone and goes into CWM Recovery, the same situation with the options (like with Marvel ROM) happen.
Right now what i want it to be able to have CWM working properly so i can wipe data/factory reset etc, to be able to install another ROM in it, i don't want to stay with the Gingerbread default version that SmartFlash manages to get through.
Any ideas?

this is the touch version. scroll down or use sensitive keys to browse

Nvm! Understood what you meant! On my way to try and get a decent ROM running! Big thanks!

Lg L90 stuck on fastboot "loading" please help

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.

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.
