TWRP mysteriously disappeared? Can't install new rom? D850 - G3 Q&A, Help & Troubleshooting

So I am running a very unstable version of CM12 and it has too many bugs. I would like to flash CloudyROM but my bootloader just seemed to disappear? I try to manually boot into bootloader with no luck. It pops up with a LG FIRMWARE UPDATE Screen and that doesn't really work out. I try to do "reboot bootloader" in the terminal emulator.
When I reboot bootloader, a screen that says the following pops up:
status bar saying 0% User b57
FIRMWARE UPDATE
DO NOT UNPLUG THE USB CONNECTION UNTIL THE PROCESS IS COMPLETE.
I can not press anything on the screen.
I don't really know what to do next. Could anyone shed some light?

The recovery doesn't just randomly disappear. You've gotta tell us either eactly what you did, but best is to just re-do the Bump process so you get your custom recovery back.

So you are stuck in Download mode?
Flash stock firmware, root it and then flash desired custom rom.

Dude you don't use reboot bootloader to get to recovery, that automatically takes you to download mode as you have described. If you're using advanced reboot just click reboot then recovery. Otherwise, turn your phone off then turn it on by pressing both the power button and Vol Down button and holding them until you see a white screen with several options (this is the factory recovery). From here, choose Factory Data Reset and confirm it. It should take you to TWRP as I'm sure its not gone.

Semi Bricked/Bricked Phone Needs Fixing

Hi Guys -
First time android user and attempted rooting using the odin method. I followed the instruction listed here http://forum.xda-developers.com/showthread.php?t=1311194 to the "T" before starting. I was doing alright until after flashing the recovery-cwm-hercules.tar, then it gets weird. It didn't flash to recovery but just rebooted to the main screen (where I could see the background picture with the locker pattern), then it immediately shuts off and the cycle begins again.
The weird thing is that I can't even access recovery mode (hold vol. up+down+power), because I'll see the Clockworkmod logo then it flickers and reboot itself. This happens every time I attempted recovery mode.
My attempts to fix it:
1. I flashed the recovery, http://forum.xda-developers.com/showthread.php?t=1315390, to see if it makes any difference. The same story happens with loading to main screen w/locker then it reboots itself again and again. Sometimes I'll be lucky to input the pattern but before soon it will reboot itself again. Same thing with recovery mode as described above.
2. Flashing the stock kernel provided by http://forum.xda-developers.com/showthread.php?t=1311229 to see if it does anything. Nope, same story for both recovery mode/home screen.
3. The insecure kernel, http://forum.xda-developers.com/showthread.php?t=1320946. Same story. nope, nope.
4. Tried these in all order and permutation. Nada.
5. Tried it both ways using samsung driver/kies.
6. Tried it both ways with/without SIM card.
7. Battery is fully charged when attempting any flashing.
8. All the above in my second computer to no avail.
I'm sorry if this might come across as long winded but I just want you guys to get the full picture. I would really appreciate it if you guys could offer any solutions or advice on how to correct this problem. Please be gentle with this first time android user haha, thanks in advance man.
Manually boot into recovery (vol up/down keys) and make a backup (be sure to do this). Then try wipe data/factory reset through recovery. Sounds like a ROM issue not a hardware issue
First off, thanks roman for the quick reply. That's the thing I can't get to recovery manually with the button combinations. When I do that it gives me this message:
[Picture]White dropbox/mail box with a yellow arrow pointing to the Android
"Verifying internal mmc block
Checksum confirmation check (0)
No need checksum confirmation already exceuted
#manual mode#"
It would then reboot and goes to the screen with the locker then immediately repeats that cycle. It doesn't have any wipe options/restart now/etc.
No way to power it down except with battery removal. I've attempted what you suggested many times too to no avail.

Ok, so if it actually boots into the ROM but reboots, try rebooting to recovery from adb -- "adb reboot recovery"
think it's a no go . i tried using adb recovery method and the same thing would occur, it would restart and seems to load into recovery mode but then I would only see the logo, then it flickers and restart itself.
then the vicious cycle of loading up to the screen-locker and restarting itself begins. guess this is the smartphone version of being friend-zoned.
Have you tried taking battery out then back in and while holding volume up/down plug it back into computer? That has never failed to get me into d/l mode. Man I hope you get it working.
Yeah I tried that and getting to download mode is not the problem. just that recovery mode doesn't boot properly in that it would restarts itself. and when i boot normally to screen, i would see the locker and background picture then within 3 secs, it would restart itself.
Guess last resort is to go to t-mobile store, play dumb, and get samsung on it. only problem is that i worry about the flash rom counter # since mine is like 10 already (my attempts to address this problem). Let's hope those tmobile reps aren't that tech savvy.
Thanks for all the help fellas, great early posting experiences so far.
I'm sorry I've read your post..and i'm confuse, if you're able to go into download mode, then why could you just start Odin and flash the recovery again. If its unsuccessful then check the MD5 to see if you have a bad download. I think you should download the recoveries files again add give Odin another shot..Good luck..

are you able to go into CW recovery ?
if so, you can mount the USB, download a stock ROM, and then flash it using CWR

I understand that but that's the a big problem. If I could go to CW it would be a different story but I can't go into CW recovery. I would be able to see the logo CWR and the version number then immediately it shuts off again and reboot. Happens every time without fail.

did you let go of holding the vol+ & vol- buttons as soon as you see the blue text in CWR ?
it can easily reboot by accident when holding those buttons and hitting power, but the buttons are so responsive it selected the first option to reboot the phone by accident a couple of times on me
I'm positive that I held it properly and long enough. I never got to the blue text, just the CWR logo showing then turns off (like you shutting off a tv) and reboots itself. Trying to flash it again with Odin didn't work either and I tried the recoveries from different sources as well.
I went to the Tmobile store today and seems like they'll mail me a replacement then I'll return my current one to them. Only thing is stocking/processing fee but it's a small price to pay if it resolves everything.
glad they will give you another one..
Dude if you can get into download mode then it can most likely be fixed by flashing stock through odin. This would save you some $$. Just saying.

Dude, I understand that it should but it's not. I've flashed the stock recovery for more than 10 times and I still can't past the home screen. It would just reboot itself in less than 3 sec. And I'm positive I flashed it properly. Believe me I don't want to spend extra money if I don't have too.

[Q] Problem with clockmod

I follows this guide to update my phone to android 4.2, but in step 13, i forgot to use clockmod recovery so I skip it. I select recovery and my phone reset but when it turn on. the update icons appears for few seconds and the error icons show up on the boot screen. I don't know what to do so I just turn off my phone. but when i turn it on again, my phone just keep reset over over again it doesn't start the android.

here is the guide that I followed
My recommendation is to go back to a more stock ROM. You don't sound particularly experienced, and this ROM is not a finished product.
You need to hold power + vol down to get back to the boot loader.
My guess is you haven't flashed the boot.img.
Let us know what you have, and haven't done in a bit more detail and we will be able to help.

[Q] Unable to get into Recovery Mode!!!

Hi
There's this Galaxy Note II (N7100) which the owner tried wrong patterns a lot and now the phone is locked and we can't use his Gmail account to unlock it. So I tried to get into Recovery Mode and do a hard reset. SO I turn off the phone hold 'Vol Down+Home+power' the phone turns on shows the samsung galaxy note 2 logo and after one or two seconds, instead of going into recovery mode that logo screen starts flickering (scrambling) and then nothing happens, the screen is black although I'm not sure if it's turned off. So now how can I hard reset? Thanks in advance

Go into download mode instead. Once there flash a custom kernel via ODIN and then reboot into recovery.

boot into download mode and flash philz recovery via odin . uninstall orevious drivers and fresh install samsung drivers and make sure usb debugging is enabled.
a detailed guide can be found here this will solve your problem of recovery http://forum.xda-developers.com/showpost.php?p=31801060&postcount=2
Note :
normally, phone should auto-reboot into recovery.
If it reboots into android and your recovery remains stock, repeat above steps and untick "autoreboot" in odin. Once flash is done, keep pressing power button until it reboots (normally will go to recovery)
when in recovery, if you choose option "reboot system now" and you get "yes - disable flash recovery", select that option to avoid stock recovery overwriting cwm

After trying to uninstall a Live Wallpaper using Titanium, my phone is experiencing a similar case as OP. I'm stuck at Samsung Galaxy Note GT N7000 logo.
MY QUESTION IS: will your recommendation work for me also? I am able to boot into download mode. I am confused though where to find "Philz Recovery" ??? Will it be also found where I downloaded the kernel when I rooted my phone?
I downloaded this file for rooting:
PhilZ-cwm6-JPLSB-UAE-5.11.2-signed.zip
over at:
http://d-h.st/users/philz_touch/?fld_id=23431#files
Is the Philz Recovery for use in Odin this one?
PhilZ-cwm6-XXLT9-ORA-5.11.2.tar.md5
I hope you can point me out to the right direction. I'm am quite new with rooting. And trying to save my once buttery smooth Galaxy Note I, GT-N7000 pre Jelly Bean.
Thanks,

soft brick??? clueless
I think my lenovo a6000 plus has been softbricked as it doesn't get pass the logo screen. also recovery mode is not opening ( tried every combination). Help me with this. This phone has really checked up my nerves. the reason for flashing this phone as it had a problem of automatically downloading apps without consent, and video apps popping out in the middle of night(time service, monkey test apps), so the only best solution i found was to flash it( tried every other possibility- factory reset, password change...etc everything). Now it has died on me, can't get pass the logo screen. Also connecting the phone to pc gives me multiple drive partitions. Please help.

I have a soft bricked (hopefully) Galaxy Note II that scrambles at the startup logo screen and goes blank. I can hear the startup sound and all on startup but nothing on the screen. I have been at it the whole night trying to get it into recovery mode so I could wipe it clean and reinstall the firmware. Tried CWM, TWRP, Philz Recovery (all using Odin) but nothing can get the phone to startup in recovery mode.
I have reinstalled the firmware as well after rooting it with CF Autoroot (again using Odin). I am sure that I am using the correct versions for this model but I have reached nowhere so far.
Now, I have two constraints:
1. The USB debugging mode is probably not enabled (the phone belongs to an uncle of mine).
2. I cannot do anything or change settings on the phone as the screen is black.
Can someone please help me out with this and let me know how to go about fixing it?
Try this: download the stock ROM from sammobile.com, open Odin, uncheck everything except f.reset time. Flash the ROM. When you see the word reset in the status window, remove the USB cable from the phone, remove the battery, replace the battery, boot into recovery, factory wipe, and reboot.

I've seen people are viewing this post if anyone know how to fix my problem please help or message me, the minimal adb won't work unless the device is turned on in usb. debugging, I can access my recovery with phone on easily but while it's powered off I should be able to get to custom recovery by pressing volume down and power while phone is off, but this method isn't working. So if I get in bootloop I can't get into custom recovery...please anyone any ideas
Well it should be as simple as holding down power and volume button down things but i guess you've already tried that method many times and it didnt work so you ask then, right?
If your phone in bootloop, you can flash tot files and it will back to stock re-root and re-install trwp.
If your phone still (or already) normal, you can download an app that can take you to custom recovery such as rebooter or power menu, thats it.
Yea phone isn't in bootloop, but if I put a Rom on phone I have no way to access the recovery because the volume and power won't take me to the recovery, so if it goes into bootloop I'm outta of luck I don't understand why the hardware buttons won't take me to the recovery, have you ever heard of this problem

How long are you holding the vol down and power buttons? It should be around 15-20 seconds, then your system recovery screen comes up, you choose factory data reset, yes, and then TWRP comes up. If that isn't working - are you sure your buttons are working OK?
If the phone is turned off is there any other way to access it while phone is off?
Yes buttons work fine I hold it down and it just goes to Verizon screen ?
Actually when I hold it down it just stays on logo and reboots back to logo over and over and over
Actually I hold it down and it reboots to logo over and over its like there's no recovery there I don't understand lol

OK... Does your phone boot into your ROM at all or are you bootlooped? If your phone boots, download an app called flashify and get the proper twrp .img file for your model and flash the image using flashify. It's an easy app to use - just make sure you're using the correct twrp .img for your phone...from here: http://forum.xda-developers.com/lg-g3/orig-development/recovery-twrp-touch-recovery-2-8-2-0-t2966129
If you are bootlooped I would suggest starting over and reflashing back to stock using the tot or kdz method. Here is a guide: http://forum.xda-developers.com/verizon-lg-g3/general/restore-verizon-to-stock-t2827878 I know it can be a pain to get the download tool working properly sometimes, so it may take some effort to get it working, but be patient (and read a lot if you get stuck) and you will get it working.
I don't know how you got borked...maybe it was an un-bumped twrp image? Either way, it is what it is, just try not to do it again Good luck.
Thanks much I'll try this
When this happened to me i would
1: remove battery
2: insert battery
3: hold volume down and lock button at the same time
4: When the LG Logo pops up release the lock button for 1 second (while still holding the volume down button), then press down again
5: A data reset/restore menu appears, and when you choose to reset/restore, TWRP boots to recovery.

OnePlus 3 Will not boot after Flashing RR

Hi! So I have been rolling with the marshmellow version of RR for quite some time and figured I was due for an upgrade. I went to update to the Nougat version, and did everything correctly, firmware, wipe, rom, then gapps. Much to my dismay I was greeted with a screen prompting me for my pattern to start android, I thought this a bit odd but went with it and my pattern did not work. I tried again thinking I may have done it wrong but nothing worked. I didnt think much of it and went to flash again to make sure I did it right, but my recovery never booted. Afterwards I got an error that was very quick and I was not able to read. It came just after the "your phones bootlader has been unlocked" etc. It was a very similar screen as well. After this, I was not able to boot up the phone at all. Once I was able to power up the phone but it simply gave me the same error and now its not starting at all. Any help would be much appriciated and thank you if you made it through this post.
First of all, you need to flash the very latest version of TWRP. If you are suffering from encryption issues and cannot decrypt TWRP, you will need to press back on the TWRP screen, and press wipe -> Format data
You will lose all your data and will be unencrypted. Make sure you have the latest TWRP, as this is vital for Nougat.

Thank you for the help, but I cannot even get into my device to update TWRP.
Try holding the power button for a minute, or try volume down + power to get into the bootloader.

Already did, it doesnt work. Black screen.
Im facing the same problem too. Cant even get adb to work ?
If you can still get into your bootloader, use fastboot commands to flash the latest TWRP.
Either hold Vol Up + Power when you phone is off, or turn it on normally and click any volume button during the "bootloader unlocked" warning screen to access the boot menu.
If you can't access the bootloader at all, then I believe the unbrick guide is your only option.
I can get to the bootloader, but when i flash recovery, it just restarts again and again.
Wipe the recovery partition first before you flash the new one.
Also, what version of TWRP are you using?
Yeah I will look into brick guides. Also going to try and let my phone charge to see if that may help. As far as I can tell it isnt charging but I might as well try.
Thank you for all the help guys, eventually what worked for me was indeed an unbrick guide. I will now be sure to read up entirely on what exactly I need to upgrade to fix this issue. For any wondering https://forums.oneplus.net/threads/guide-mega-unbrick-guide-for-a-hard-bricked-oneplus-3.452634/ This was the guide I used to fix my phone.
