I was trying to get lineageos on my s6 edge+ but it is stuck in a samsung logo loop after being unable to flash the rom and now it won't go back into TWRP either.
Initially I flashed the official TWRP for the zenlte which worked fine, it just did not want to install the rom due to apparently not having any device data. (Rom is for zenlte, this device is . (or something along those lines))
after a few attempts and doing a quick wipe I flashed an unofficial twrp and thats when it started looping without being able to get back into recovery mode.
Download mode does still work after a power off but flashing the official twrp again makes no difference.
This is a little beyond me and I'm not entirely sure what is going on.
The last phone I installed a custom rom on was an s4 so I'm a bit out of the loop with this new security stuff. I would have expected to at least be able to boot back into twrp.
Ok some progress:
Recovery mode worked again after leaving phone off (but still attached to computer) for a while. (I had given up but decided to try again after a few hours)
Partitions were missing / corrupted. Did a full format.
Installing rom still gave the 'device type is .' message.
Edited the rom zip to allow "" and " " ( in META-INF\com\google\android\updater-script )
Flashed rom + gapps + magisk in 1 go.
This ended up in LineageOS trying to start but rebooting into recovery after about 5 minutes.
Re-instralled just the rom, this gave a few errors about Magisk missing, re-installed Magisk as well before wiping cache and rebooting.
Now it came up with the welcome screen rather quickly.
Weird, but problem solved any ways.
Thanks! That was also my problem.

Phone: LG Spectrum
ROM: Cyanogen 10.1 3 or something
CWM: 6.0.4.7
I was in the process of manually installing CWM Touch via Rashr Flash Tool to replace an old 6.0.1.1 non-touch version i had on it before, and when I successfully got it installed, the app asked if I wanted to reboot into recovery. So I pressed yes, and it did.
Unfortunately, it never seemed to remove it afterwards because after every single reboot, it kept going back to recovery, not loading the android OS.
I've tried the following with no success:
Clearing data factory reset
Clearing cache
Clearing Dalvik cache
Full restore to V6 stock
Full restore to Cyanogen (I made a backup when I first got to CWM Touch)
This is the current behavior of my phone:
When powered on, it will display the LG logo, then it will flicker to black and then fade in the LG logo again, 5 seconds later recovery boots. If phone was off and you insert USB cable to charge, the LG logo appears, but the battery mode sort of screen never comes after. Its just stays at the LG logo, and never turns off the display.
It will keep rebooting to recovery no matter if I even tell the recovery to reboot to bootloader.
I don't know exactly how the bootup structure is for androids but the only thing I can think of that may be the issue is the recovery itself if it wasn't the app that caused this. It just doesn't make sense that after a full restore, it would still have an issue, other than the recovery itself, UNLESS there is some secret boot instruction file that's stuck with a "Reboot_to_Recovery = 1" parameter.
Since this thing is stuck in a recovery boot, how would I be able to manually, without OS access, reflash another version of CWM on the device? Or if there's another possible way to fix this, please help me.
Maybe the ROM hasn't flashed on your phone properly .try again with a clean flash. may help
HiT Thank$ If HelPed
I believe this is independent of the ROM. I had noticed in preparing to flash a new ROM that instead of restarting to the OS, it restarted to the recovery. I didn't take much note of this, but it was clear that this problem began when I flashed the new recovery. Also, the fact that I had used 2 seperate, very different restores (full restores) with no success means that it couldn't have been the ROM.
My only probably clue right now is that the recovery is to blame (which is weird since CWM notes 6.0.4.7 as compatible with LG Spectrum. I had 6.0.1.1 before with no issue). I have no idea how to change this recovery however, given that I can't even boot the OS at all, and there doesn't seem to be a "flash recovery' option in recovery (which is kinda annoying).
Hi. Just got a Note2 which was running 4.4.2
I downloaded Odin3-v3.07 and got root access. I then used a checker to confirm.
From there, I used the TWRP Manager to install 2.8.7.0.
I think this is where things went wrong. I know I selected the correct phone model, but it gave me an error saying something went wrong ( I think it said something about me having the latest TWRP) . Then my phone rebooted and took me into TWRP.
I made a backup and tried to flash the CM12 rom for sgh-i317m.
That's when I noticed I couldn't get out of TWRP. Rebooting or pulling the battery has no effect. Phone keeps booting into TWRP. I tried wiping delvic cache, cache and other things, but no matter what I do I can't boot into the OS. I tried restoring and it says it was successful, but again am stuck in TWRP. I've now spent the last hour searching for a way to get out and still can't find a solution. Any help would be greatly appreciated.
Notes:
Not sure if this has anything to do with it, but I had forgotten to enable USB debugging when I was in my OS.
Another thing I noticed is when I open the terminal command, there's a running boot script error: E:/sbin/runatboot.sh process ended with ERROR=1
Problem resolved: I booted into download mode and used Odin to root again. That seem to overwrite whatever was causing the Note 2 to be stuck booting into TWRP.
I enabled USB debugging and installed TWRP again. Got the same error but this time chose not to reboot into recovery. Then I rebooted manually, and the phone boots into the OS. I powered down and held Vol up + power + menu and released power button at Samsung logo, and was successful in booting into TWRP. Exited and rebooted took me back to the OS. So I'm not quite sure what it was the first time around that got me stuck into booting TWRP everytime.
Glad you got it fixed! :good:
I'll close this thread.
I searched the forums before posting. 73 results came up and I read through and followed instructions of 7 different posts that seemed similar to mine (including the ones that appear when making a new thread), but nothing has worked or I haven't found a situation like mine.
Hi.
I have a HUGE problem and need help.
I was on Cyanogen OS 12.1 and decided to install the latest Cyanogen OS 13.1. I downloaded the flashable zip. Booted into TWRP recovery and installed the zip file. I had always allowed my phone to reinstall Super SU in the past with great succes, but it seems I shouldn't have done that according to someone in Oneplus forums. Now my phone is stuck on the bootup animation that says "Cyanogen MOD ready". I also cannot boot into the recovery or safe mode using hardware keys. Please help! I don't want to lose my phone or my data!
Thanks for any advice.
note: I used the signed flashable zip from here.
EDIT: I was able to boot into recovery using the command "fastboot boot recovery.img". I cleared dalvik cache and flashed COS 13.1 zip. Currently waiting for phone to boot. Hope it doesn't get stuck on the bootup screen again.
EDIT2: It looks like my phone has booted successfully and is now optimizing apps for COS update! If I don't follow up, it means everything worked out great again!
EDIT 3: My phone finished "optimizing" apps. I thought it would take me to my launcher as all other times I've updated. To my surprise, the phone seemed to reboot and was stuck on the "splash screen" (Cyanogen MOD ready). After that, I got the "Android is starting" "Optimizing app xx of xxx" message again, which is incredibly weird and I think my phone might be in a bootloop. PLEASE HELP!
EDIT 4: I remembered that I did a nandroid backup last February so I restored it with "restore" in TWRP. My phone has been stuck on the "Cyanogen" boot screen for about 40 minutes. I'm lost.
To recap everything:
1. I was trying to manually upgrade from COS 12.1 to COS 13.1
2. My phone was rooted, had TWRP recovery and ADB debugging was enabled in dev options. I can enter fastboot mode using hardware keys. I cannot enter recovery using hardware keys (shows a blank screen), but I can enter recovery using "fastboot boot recovery.img.
3. After I flashed COS 13.1, I was asked (in TWRP) if I wanted to install SU and I said yes and flashed it. This is when I was in a loop of being stuck on COS 13.1 splash screen for about 5-10 minutes and then my phone was "optimizing app xx of xxx" for 15 minutes and then rebooted and did everything all over again.
4. I tried to restored a nandroid backup using "restore" in TWRP, but phone is stuck in "cyanogen" splash screen for more than 40 minutes.
No replies...
Not sure what to do at this point.
I ended up wiping data and performing a factory reset through TWRP. Might try to upgrade again in the future.
Title pretty much says it, I have a custom rom installed which works, but when reboot my phone, TWRP is automatically opened after the initial samsung logo. I usually have to reflash my custom ROM (without wiping any data besides cache and dalvik) and the ROM installer will then reboot into the ROM, however this means when my phone turns off, my recovery is booted up instead of the ROM. I'm really confused
S6 is a SM-G920F / ROM= Tyrannus v 28.1
Some background into the problem - [This is a quote from my previous post: http://forum.xda-developers.com/gal...ing-stock-t3423351/post67859895#post67859895] "When i tried flashing however, somehow ODIN froze and i made another stupid mistake of restarting my phone from download mode which resulted in the phone being froze on a screen saying " an error has occurred while updating the device software use the emergency recovery function s6 "
So after this happened i then flashed TWRP with odin to solve the quoted error message and i think it was at that point that the bootloader was configured to initialize recovery on bootup as oppose to the actual ROM, not sure though so any help on the matter would be greatly appreciated.
TL ;DR : S6 boots recovery instead of ROM - Possibly bootloader error?
Sooo... it fixed itself. All is well.
If anyone else ever has this problem all i can really suggest is perhaps going into terminal on TWRP and writing reboot? However, my one just fixed itself so we all good!
Hi everyone,
I've been trying to get TWRP to stick for a while now, but still haven't been able to get it to install. A while ago I managed to flash Resurrection Remix using Lineage recovery which does work, but since Lineage recovery is quite limited, I really wanted to get TWRP to work. Since TWRP 3.5.0 released yesterday, I gave it another shot hoping that they fixed the issue, to no success.
I can get into TWRP just fine by temp booting it with fastboot, but after flashing the installer zip, any recovery that was previously installed gets wiped and the device will reboot when trying to get into recovery. I can still boot my phone otherwise.
The steps I took to get to this point:
Unlocked bootloader
fastboot boot twrp.img
Decrypt using screen pattern (successfully)
Flashed twrp installer zip (no error messages, process finishes successfully)
Reboot into recovery (both from twrp and bootloader at a later point)
Things I've tried:
Use a different TWRP version. Same problem as described above on both 3.4.x and 3.5.x, can't get it to decrypt on lower versions due to Android 10.
Install to recovery ramdisk, this just breaks things even more, probably because it's an A/B device?
Try a different recovery. Lineage recovery works just fine, but it's very very limited. Would really like to get TWRP working.
Trying to flash the zip results in no error messages, but any previously installed recovery gets wiped and magisk is uninstalled, which leads me to believe that it has done at least something to the boot img.
Thank you in advance.
EDIT 25.02.2021:
- Attached TWRP log
EDIT 12.03.2021:
- Log didn't want to attach, they can be found here: https://pastebin.com/awnhHDBU
Same question here. It seems that you can only boot from TWRP, not install it.
Tried installing again today, to no avail. However, I was smart enough to save the log this time. I have attached it to the main post, would be much appreciated if someone could check it out.
