G2 cyclically restarts....Help, please. - G2 Q&A, Help & Troubleshooting

0. LG G2 4.4.2 D802 CIS
1. Get "root" by Stump 1.2.0
2. Using AutoRec
3. Reboot in recovery mode with TWRP 2.7.0.0
4. Made “backup”, and copied it to PC
5. Made Wipe, Advanced Wipe
6. Flashing CloudyG2 3.3 from external USB OTG
7. After that got black Screen after LG logo
.....
8. Download D802_PATCH_GO_LP_V1.1_droidth.zip, and installed it from Recovery Mode by TWRP
9. Reboot system, now:
Phone cyclically restarts from the beginning and to LG logo, and so on….And I cant enter to the recovery mode. Cool. That can I do, instead throw in the trash?))

I assume you're following directions from this post: http://forum.xda-developers.com/showpost.php?p=61710456&postcount=1304
If so, I see a couple issues. You did not update TWRP to 2.8.7.1 as indicated, and why are you flashing from USB OTG always copy to your internal memory. You likely can get back to recovery, but it takes timing and patience. I've been in the same situation before. Just an FYI we call a cyclic restart a bootloop.
While it's doing the startup hold the power button until it powers off, it will restart again after. So here's the trick as soon as the screen shuts off you have to let go of the power button and immediately do the vol down power button combo, hold them both until recovery starts. If held too long it will reboot again. Like I said timing is everything, but you should be able to get it with patience. Good luck!

You did not use latest TWRP and you did not flash LP bootstack. Go to recovery, delete system, data, cache, flash latest TWRP, then flash LP bootstack, then Cloudy again
To enter recovery, press power+volume down, hold until you see LG logo, then FAST press power+vol down again, white screen will show up asking to factory reset. press power button, then press power button again. phone will enter recovery.

Is it correct?
1. Hold Power on Lg logo
2. When the screen shuts off:release power button and quickly push Volume+Power on the some period?
One time i seen screen with proposal of erase system, i pushed Yes...and now it rebooting again. And some time it was button hardware assignments screen.

2. You mean flash Bootloader Changer 2.2, and choose Lollipop bootstack in it?
Thanks.

You can flash latest TWRP and LP bootstack in TWRP. They are both ZIP files so it will work. I would give you links but i'm not sure which G2 variant you have

thanks, but first of all - i can not enter to recovery mode, ordinary button combination do not work. As i wrote before.

If you really can't enter recovery you'll have to "KDZ".
Look over there: http://forum.xda-developers.com/showthread.php?t=2797190
Find the appropriate rom.kdz, flash it with the tool.
If this worked, root stock LP, Autorec v2 it, enter recovery with key combination or if this fails with tools like "Quick Reboot" from play store.
DO NOT FORGET to wipe system, data, caches and to flash an appropriate stack, then flash rom, gapps and supersu. You can do this in one step.
If you want to shut down your phone, just press POWER for around 10s. Do not flash with battery under 50%.
You may find SRKTool useful.

Try entering download mode and flashing stock rom through KDZ or TOT method. There is a thread called "G2 go back to stock" in G2 General you will find all instructions there
tip: disconnect usb devices like usb wifi dongle, web camera and external hdd, they used to cause me problems when flashing KDZ

can somebody help? stuck on boot logo

i install the paranoid android rom on my nexus 7 and now its stuck on the bootanimation of the paranoidandroid rom i didn't wipe the data but i did wipe the caches so if somebody can tell how to get out of it i will appreciate the help I'm new to this thank you
Hold on the power button (I believe) to turn it off and go back to recovery and re-wipe and reflash. It happened to me once. Or wait till the battery dies.
Hold down the volume up (might be down, can't remember) and power button down at the google screen. Then the screen should go black, quickly hold down all three keys (up, down, and power) and it should bring you to recovery mode. :good:

Hi. Have the same problem. When trying getting into recovery mode, nexus stuck on google logo. Please help. I don't know what to do.
Ran into the same thing and now fixed
I had the same problem and finally figured out (I think) that it was because I was installing the ROM and the gapps at the same time. I installed just the ROM and then booted. Then rebooted to recovery and installed the gapps.
1. Hook it up to the computer.
2. Shut it off. Hold power. Then hold Power and Down till at the bootloader screen.
3. Flash recovery "fastboot flash recovery recov_filename.img". I used the zip from thread 1837401 on these boards to get fastboot and clockwork recovery.
Sometimes have to do this 2x if won't run through. If it sits doing nothing, go down in the menu and reboot bootload and then rerun the command before touching anything on the GN7.
4. Go into recovery, flash PA and reboot. After got in and running, reboot and install gapps.
5. Enjoy the awesomeness!
LOL you have to wipe the data. use tib to get your stuff back. Wiping the cache is a meaningless gesture if you haven't wiped the data. If you had followed the instructions in the rom thread, there would be no problem for you.

How do I boot into recovery from a bootloop?

I flashed a wrong file in twrp and my phone went into a bootloop. I want to boot into recovery to reflash the ROM but I can't do it, the phone is stuck into a continuous bootloop (stuck at the Samsung logo and vibrating over and over again). I can boot into download mode using vol down + power + home, but vol up for recovery isn't working.

1. Boot in DOWNLOAD MODE and flash the correct TWRP via ODIN again. Done.
2. If the step 1 doesn't work. Boot in DOWNLOAD MODE, reflash STOCK rom and reflash the TWRP, the one good for your device. Done.

Secret mode wasn't working in the Samsung browser so I flashed a zip that I found on xda that supposedly fixes this issue and cleared the cache and dalvik cache. I don't see how this could have erased twrp from my device. I currently don't have acces to a computer so I can't use Odin, is there really no way to force shutdown it or something?

Enter download mode, once you are in download mode press at the same time power + home + volume down button. As soon as the screen goes black release the volume down button and press the volume up button immediately, then it will boot up to TWRP

TWRP and Root gone for me on Z1 Compact and my USB port is broken. Please help

Hi, I see a lot of posts everywhere, here and on reddit talking about how the latest PA wipes TWRP and root. I've never flashed a rom that did that. I'm not a newbie and would have been able to fix it, but my USB port is broken. I've been charging via the magnetic port. I don't like that people aren't being taken seriously with this request because in most cases, sure you could use flashboot, but in my case I'm locked out of my device.
I would use something like Rashr, but I don't have root. The only way I can think of to get root is to use one of those sketchy apps like KingoRoot and then install Rashr but I have a feeling that would probably brick my device and since it's "usable" (but I can't get into recovery or root it) I should probably cut my losses and sell it.
I think this release should be pulled if it's causing this many problems. If the release is updated with a working TWRP, would I be able to fix it through the PA updater, or is that only system files and no recovery?
We haven't shipped with root in a LOOOOONG time.
I've never seen a ROM flash remove recovery. The ROM itself has nothing to do with recovery, and doesn't actively remove it.
I tried Paranoid Android on my Xperia Z3 Tablet Compact, I liked it a lot, but P.A. breaks TWRP so I'd be forced to reinstall the rom from scratch with every rom update so I can't use P.A.

Not required . It is very easy to get twrp after flashing PA. It is a problem with sony devices. Follow my guide on how to get twrp, but download the twrp for your device and not for z3 compact

Im not a 100% sure this will work, it mostly wont work, but try using kingroot to get root on the device, then use flashfire to flash recovery to boot/FOTA/Recovery partition depending on your device. Then try getting into recovery. But how did you get recovery in the first place if you had a broken USB? Why would you take chances?
Hi panzerox123, Thanks for link to guide but no go - I followed that guide five times and failed five times. It fails at 'To enter recovery mode, power off your phone, and press and hold Vol-down and Power button together until you see the sony logo.', it boots stock android instead. I tried flashing to Recovery and to the FOTAKernel - both failed. Recovery doesn't work with stock or Paranoid Android on this Z3TC but does with CM12 and FreeXperia.

Really? This is how I got recovery back when I flashed pa. Are you sure fastvoot is working in your device? When you hold vol- and power button for around 10 seconds, you shoyuld see Sony logo, and then screen flashes and enters recovery.
Another question, did you download the correct twrp for your device? The link in the thread is for z3 compact phone
My tablet is the SGP611 'scorpion_windy'. Firmware: SGP611_23.5.A.1.291_UK.ftf TWRP: twrp-3.0.2-0-scorpion_windy.img (https://dl.twrp.me/scorpion_windy/twrp-3.0.2-0-scorpion_windy.img)
Vol- and power buttons are pressed until I get the Sony logo but it doesn't enter recovery - instead the tablet boots. Unlike with CM12, I don't get to see the violet led either.

Hmmmm very weird... are you on stock or pa?
Wait... Flash the latest firmware available for your device using flashtool. It updates bootloader so you can enter recovery using the above.
If all else fails, there is another method to update pa without starting from scratch every time. Can't explain it right now, I'm on Mt phone, when I get to lapptop , I'll explain
23.5.A.1.291 is the latest firmware that I downloaded with XperiFirm http://forum.xda-developers.com/cro...xperifirm-xperia-firmware-downloader-t2834142
Either stock or P.A. won't enter recovery.

The only method that will work for stock on this tablet to get recovery right now is this one: http://forum.xda-developers.com/z3-...torial-stock-android-marshmallow-6-0-t3409486 using RecRoot.
As for P.A. - attempting to enter recovery results in continuous bootloops until reset.

That only happens when the wrong recovery is flashed...
RecRoot is only used with stock because it was designed for the Z3 phone so obviously that is no good for our purposes as would still have to flash the correct version of twrp.
So I either flash the base.img from CM12 (lollipop) scorpion_windy or FreeXperia 6.0.1 (marshmallow) scorpion_windy, then flash TWRP scorpion_windy. Then get into recovery, then wipe dalvik, system, data, cache, then install paranoid android, then wipe dalvik + cache and finally reboot. Well it boots fine but booting in to recovery just ends in bootloops.

Same here.
Entering Recovery from ADB or standard hard buttons (USB + Vol-Up several time at boot) caused the boot loops.
The only way I found to enter the Recovery mode is: Unplug USB, Vol-down + Power press at the same time until the sony logo comes up.

That is not how you enter recovery, that is how you enter fastboot mode... To enter recovery, you need to have a recovery installed on the recovery partition. To enter it, press vol-down+power button until you see sony logo and then leave the buttons

When the device is normally powered up, the status led turns purple/pink. There if the Volum-up (down as well?) is pressed a couple of time, the LED changes color and the device enters the Recovery mode.
Of course you need a recovery image to be flashed in the recovery partition.
The problem here is that with some ROMs (i.e. AOSPA) is not possible to enter the recovery mode via "purple/pink led" procedure. The device will enter a reboots loop.
This procedure works properly with CM12.1 and CM13.

How to boot into recovery
Switch off your Xperia Z first
Switch it back on and the time when you see your phone’s LED notification light turn purple or pink — start pressing either the Volume UP or Volume Down key a couple of times and your phone will reboot into recovery

That is when your recovery is embedded with the kernel. If you have the latest marshmallow build for Sony, it allows to to boot into recovery partiton .

LG V20 US996 Network Unlocked Cannot go into Recovery Mode

I am trying to root LG V20 US996 Network unlocked by following all the instruction step by step, everything is good from unlocking bootloader to installing TWRP recovery but I cannot boot into recovery mode at all. I did many attempts. Does anyone have any idea? Here is the screenshot of recovery installation. Did I miss anything here?
After flash TWRP, you need to turn off the phone, after that hold Vol - and power button at same time untill logo LG appear, release power button and push once more, device will go to factory reset, yes two times, your device will reboot and go to TWRP.

Thank you so much but I was able to root and install TWRP and Supersu successfully before I read your post. You are exactly right, I did what you said. Device had to go into factory reset, click "yes" and I had to install "supersu" zip by doing adb sideload. Once again, thank you very much for your input and most valuable time. I really appreciate that.

[Help] LS997 DirtySanta Stuck at Secure Startup

LS997 (September 2016 security patch), got to the end of root and couldn't reboot into TWRP recovery. The device is recognized in ADB while in fastboot but when I'm at the secure startup it's unrecognized, like USB debugging is disabled.
https://forum.xda-developers.com/v20/how-to/guide-root-twrp-lg-v20-using-dirtysanta-t3722278
If you've hit secure startup the phone has likely booted into regular Android far enough to replace twrp with stock recovery. Reboot into fastboot and reflash twrp (you can use the newest twrp if you want). Once done flashing unplug from PC and pull the battery. Reinsert the battery then boot into twrp via the factory reset/volume button method: hold volume down, press power until the screen turns on then (still holding vol - ) tap power repeatedly until a prompt to factory reset appears. Approving it twice boots twrp if it's installed, otherwise stock recovery will do the reset.
Once in twrp go to wipe, then format data (type yes to confirm), then go to reboot, then recovery. Once twrp restarts flash your choice of magisk/supersu.
Once one of those two is installed it makes it so twrp won't be replaced.

Did this, got to the set-up screen (languages, accessibility) and an error ¨com.android.phone has stopped¨ spammed the screen. I tap ¨stop app¨ and the pop-up comes back immediately.
I tried to fix it by factory resetting (in the settings, NOT using the volume down/power button menu OR TWRP) and now I´m stuck in TWRP. Every time I try to reboot to System, it boots to TWRP now.

Reflash your variant's official KDZ using [PARTITION DL] with patched LGUP leaving [aboot], [abootbak], [recovery], [recoverybak] partitions unchecked.
- Once the flash finishes & phone reboots, do a battery pull so phone doesn't fully boot (wiping recovery & encrypting data)
- Insert battery again
- While pressing volume down button - reinsert usb cable so it boots into fastboot mode.
- Follow dirtysanta guide for your variant from running step3.bat onwoards (which flashes TWRP back into your otherwise stock phone).
LS997, no official KDZ. Use VS995, but dump everything with LGUP (bar userdata) before hand
