I recently unlocked and rooted my nexus 6, installed twrp for back up. Then I wiped before making a back up. No I have no os on phone. Is there a fix or am I screwed?
Try using fastboot to flash factory images
Just grab a factory image and flash it.
Remember wiping a device does just that. Wipes it clean
The thing is, I can boot into recovery, but my phone does not show up on my laptop. So I am not sure how to load a factory image. Thx in advance for all the help.
If it doesn't connect while in recovery, uninstall/reinstall drivers.

Boot in to recovery, choose reboot system, TWRP will say, no OS installed are you sure? answer yes / swipe, TWRP will ask/say your device is not rooted, do you want to root it? Swipe to confirm.
Reboot your phone, pressing power and volume down, choose recovery mode again, your phone should show up on your lappy.
If not, re-install drivers - adb/fastboot as mentioned before.

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
Sent from my Nexus One using Tapatalk
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
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.

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.

use adb push UPDATE-SuperSU-v1.86.zip /data/media/0
to get the file on the phone
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
I'm having a issue with my sons Nabi2 pretty similar. I messed up bigtime guys I rooted it and started messing aroung with the system files. Then didn't get a boot afterwards, wiped everything from twrps system, data, the whole shabang! Even lost my root! and access to on board flash cause I've been trying to recover using twrp with absolutley no luck. I still have the original stock unrooted backup saved to my pc from when I first installed twrp. Can someone please help me? I'm really out here trying to reach out for some help. didn't even know where to post this. Thank you guys. Note to moderators: If this is the wrong place to post this then please point me to the right direction and I apologize.
Hello everybody,
I am having severe trouble with my HTC one mini 2: After an update to TWRP 2.8.5.0 the phone gets stuck at the CM12 logo.
After I got the phone, I installed CM 12 with TWRP 2.7.1.0. Everything was working fine, besides the well known problem that TWRP freezes from time to time.
Yesterday I wanted to update to TWRP 2.8.5.0. I performed the recovery flash and everything seemed to work fine. Also I erased the cache. I used the following commands:
fastboot erase cache
fastboot flash recovery recovery-twrp-2.8.5.0.img
After that, I wanted to reboot my phone. Unfortunately, this did not work out at all. My phone does neither boot to CM12 nor to recovery. It does not react to the Power button. I can restart it by holding POWER + VOL UP but the phone gets stuck at the CM logo and will not move further. Also, I can not boot to recovery.
Also, the phone is not available via adb/fastboot. adb/fastboot does not show any attached devices. Adb/fastboot can only detect the phone, when the phone was running out of battery and is attached to the PC but not yet turned on. In this case, adb/fastboot detect the device, but mark it as "unauthorized" so that i can not connect to it.
I am kind of desperate. I hope somebody con help me with this issue.
Thanks in advance.
Cheers,
braumeister
hey guys,
does anybody have an idea what to do about this problem?
Is there any way, I can flash a new stock rom to the device via the SD-card?

THX for your help.
Unfortunately I can not install another TWRP version as I can access my phone neither via adb nor via fastboot.
Both, "adb devices" as well as "fastboot devices" do not recognize my phone. Also I can not access recovery. I tried "POWER+VOL UP/DOWN" but it did not work.
Same problem
HEy guys,
like braumeister said... I have exactly the same problem.
Is anyone here able to help us? That would be great!
@fleischball
You are probably on a bootloop. A soft brick. It happens when you dirty flash ROMs.
The simplest solution is
- wipe dalvic cache/cache via your recovery
If this doesn't work
- wipe cache + dalvic cache + data + android secure.
- reflash your ROM
- again wipe dalvic cache + cache
- reboot
This method is called clean flash.
Hope this would be helpful for you.

After you reboot with pwr+vol up you have to hold pwr+vol down exactly when the phone reboots to enter bootloader.

Can you boot to recovery?
VOLUME DOWN + POWER
Once hboot appears, release the buttons and use the volume keys to navigate to recovery.
Once in recovery, wipe Dalvik Cache and Cache and then attempt to boot normally. If that doesn't help, I would boot to recovery again and WIPE DATA/FACTORY RESET.
Hope this helps. Let me know what happens.

Install ADB and fastboot on your PC. Connect your phone to your computer and use fastboot to boot into recovery. The steps are already on the site so I'll leave you to find them.

The quote got messed up in your post above so I wasn't sure what you were having trouble with. Unless it's the systemless version, flashing Supersu (or any other root) changes your system partition. Wiping data or the caches won't fix that. The first thing to try is reflashing your ROM. If that doesn't work, you could use the RUU to go completely back to stock.

Never seen that before. Maybe md5 error? If so, it could be that the files aren't downloading correctly for some reason.
Oook i solved the problem and now my phone is ok again,i had problem copying roms to my phone,i tried on mac and now its fine..thank you very much for helping you can close this thread
I just got the phone today.
I was trying to follow this guide to install lineageOS https://wiki.lineageos.org/devices/s2/install
Flashed twrp and got up to the 3rd part. I was about to start flashing the rom but the recovery mode was asking me for a password I didn't have. I never set a password on it.
So I tried doing a factory reset and now when I try to reboot it, it gets stuck on the boot screen with the LeEco logo and powered by android etc.
I can still boot into recovery. I tried wiping the cache and dalvik cache and factory reset it again but it didn't help. I didn't try wiping anything else yet since I'm afraid to break it.
I did get twrp on but I did not install any roms yet.
All I did was the factory wipe and now I'm stuck.
I have no important data on it, so I don't care if I have to reset everything.
If I can just get it back to factory default so I can start over, I'd be fine.
What's the recommended course of action?
Sorry I'm kind of a noob at this so detailed instructions would be appreciated.
I figured it out.
In recovery mode, mounted the phone to computer
Computer didn't recognize it at first so had to go to device manager and change the driver to read it as composite usb
Moved over the rom I wanted to flash and just installed it like I was planning to
Another possibility would have been an OTG adapter. You don't have any problem with windows drivers that way
