[help] [oneplus3] [stuck in boot logo] [softbricked] cannot boot into system [solved] - OnePlus 3 Questions & Answers

Hey boss., after flashing open beta 12, the phone started hanging now and then. I tried to contact oneplus forums and they asked me to send the log files. Since they took too long to respond, I went to oneplus service centre. They flashed my phone with old oxygen os and the phone didn't start. It went into bootloop
Then I asked them, they said motherboard is corrupted. I left the place and I requested online customer support from oneplus. They too flshed and concluded the same. Can I know whether flashing/sideloading openbeta created this issue? If so, can you provide me support to avail the warranty on the phone? or recover it via any other method or process?
Please respond as soon as possible. My communication with the world has become limited after this issue. I hope there is some sort of support.
Also note that, the phone can boot into fastboot mode, but bootloader is locked. It can boot into recovery. I tried wiping everything, but the phone is not rebooting.
When I start the phone, it stucks in the boot logo and after a while, the screen becomes blank and a white color notification LED is glowing.
Kindly help me.

i had the same issue last week after updating to 13..and i tried to flash the black theme..it went black..i had nothing....it was like it was bricked... here's how after many failed attempt's..i had to clean out all files including backups.wipe data i had to wipe system i had to clean out all previous files.from TWRP recovery.then i had to download the latest software release then put the zip file in my phone storage not in the download file ..then i had to flash stock recovery.then install the new system..and i made the mistake of trying to use some of my app backups like for one estrong file ..all of them were corrupt.so start fresh.

You might try this unbricking method:
https://forums.oneplus.net/threads/guide-mega-unbrick-guide-for-a-hard-bricked-oneplus-3.452634/
Though your device isn't hard-bricked, this would reset your device to the absolute factory settings (watch out, your data will be erased) on an older OxygenOS version.
I would recommend the 2nd Method, as it restores all partitions to factory settings.
I might also know where your issue came from:
Though you can flash the Open Beta (or any other ZIP from OnePlus) through the Stock Recovery, OnePlus states that you need to be on an unlocked bootloader for not bricking your device.

It worked, but no network connection or wifi connection!
Is there a way to bring them back?

You might try to unlock your bootloader (There are giudes to do this) and flash a OxygenOS package from oneplus.net through the stock recovery, to ensure the firmware is OK (Do a factory reset from recovery!). I don't know if the Unbrick Tool only restores corrupted partitions or all. It might have installed the wrong system over your previously installed firmware if only corrupted partitions are restored. Keep the bootloader unlocked to be on the safe side (After some time you will be able to just ignore the boot message and you have better access to fastboot and recovery)!
Also, GG to OnePlus for (fake) Motherboard corruption!
About warranty:
Warranty should be ok as long as you won't do hardware modifications (I think).
Bootloader unlocking is definitely safe

No, reflash the OxygenOS package of the same Version that is installed by the Unbrick Tool (If you can still get itfrom oneplus.net) and then check if Network does work. Also, check your IMEI.

I think you might have a corrupted EFS partition. That's y you don't have a working network. Check whether your device show a IMEI under about phone.

EFS doesn't have an effect on WiFi.
That's why I think that it is a firmware issue

I think, I have solved it guys. I'll let you know once completely under control

So, Thank you very much for your support. With this little support from you and my previous Foresightedness helped me restore the phone.
So just in case if any one else faces the same or similar problem, this is the process:
STEP0: If there is any partition corrupted, the device don't boot properly. And, The customer care/ sevice centre guys state it as motherboard problem. Donot Panic. Always take TWRP backup whenever you change your ROM. This Backup helps you to restore whenever you're in trouble. In this particular case, ESF backup is required. So, take a complete backup (everything) in TWRP, it saves your ass.. keep the backup in your PC or any safe Storage (the complete TWRP Folder which is in Internal Memory) before flashing any custom ROM.
Step1: Follow method2 in this guide: https://forums.oneplus.net/threads/g...plus-3.452634/
Step2: if everything is alright, its done. Otherwise, The device boots up with some missing features and details. At this time, you have to unlock the bootloader. See The forum to know how to do it. Basic searching can give you the method.
If you can transfer the TWRP folder from PC to Phone, it's good. But the phone boots itself because of missing firmware. Even Bluetooth couldn;'t be used.
In my particular case, I couldnot copy from PC to mobile or viceversa. So, you cannot copy back your TWRP folder in this situation.
So, Unlock bootloader. Then reboot to system (without doing anything)
Step3: Reboot to bootloader and flash TWRP 3-0.2 version only. otherwise device will be encrypted.
Step4: download Ressurection Remix ROM version : ResurrectionRemix-M-v5.7.4-20161113-PUBLIC-ex-oneplus3 or you can experiment with any other custom ROM but only android 6 (*Marshmallow). Also make sure that you have universal adb drivers. install them if not (search in the forums.)
Step5: goto TWRP recovery, in this, goto wipe option. Drag the swipe to wipe button here. (normal wipe).
Step6: Now, in advanced options, select adb sideload option and select the two wipes in the next menu. Start ADB sideload in the TWRP.
Step7: Now, Start the adb sideloading the custom ROM from your PC. You donot Require Gapps for transferring a file. So donot flash Gapps.
Step8: After the sideload is complete, reboot into system. Now you can transfer files between phone and PC. Now, Copy the Complete TWRP folder into the internal memory. A pop-up asks for merging the folders. Allow the merging, even if you have another TWRP backup there. They don't overlap.
Step9: Now, Boot into TWRP and restore completely. The phone boots up properly, this time. Everything works as expected. every mysterious problem is solved. Now you will get update request if you are on previous version of OOS.
Last but not Least: Please do not use any app recovery tools. they may cause issues while following the above steps
Thank to every XDA member, helping us save the time and money we spend at service center.

Yes, boss. The EFS is corrupted. But, thanks to TWRP, it also has the option to backup EFS, modem. SO, I used my old backup from Jan2017 to restore it back.
But, TO place TWRP back in phone, the original OOS3.1.2, even after reflashing didn't support. I thought for a while and flashed the All loved RR (MM) . THen, it gave me the scope to t/f the folder to internal memory.
Now, I restored the EFS , Modem, sytem with data. and hell yea!! the phone is back to life.
Complete Backup, Atleast once for 3 months saves your ass..

I am glad it helped. That's the power of Xda.

My OP3 is stuck on the boot animation only while booting up Oxygen OS. At first I thought it was bricked but as I proceeded I found out that it isn't and i'm able to boot other OS on it. I've had Resurrection Remix which I had no problems flashing whatsoever. But I'm having this problem with Oxygen OS. Has anyone experienced this? What do I do? Please help.

[Q] TWRP + OTA update = bootloop! help needed!

Hello everyone,
Today showed up on my Gpad an update that automatically started to download.
So I thought ''if it is downloading, why don't I give it a try?''
Big mistake.
I am rooted with TWRP 2.7.0.0 and stock 4.4.2 rom..
My Gpad after I press confirm it tried to reboot. After the device shut down and try to power on, it stuck in a bootloop on TWRP.
Every time I try to power it off and then power it back on it starts on TWRP and stay there even if I press reboot on TWRP it does the same loop.
After this idiotic move of mine I would like to have help from someone who knows how to restore the device..
Also is there any way to restore the device in TWRP or to do the update manually from the file that is already downloaded in my device
(from TWRP)?
Any help would be very very appreciated!

Did you not make a back up after rooting your tablet? If so, simply restore from your backup.
generally, it is advised that before you update a rooted device's ROM, to create a nandroid backup first, just to be sure. As OTA's from non-OEM's aren't as stable as OEM's, nor do they provide warranty if you get stuck in a boot loop. To fix the issue, download your ROM image to the "root" of your microSD, go to recovery, wipe cache/dalvik cache, then try to install the ROM image. If it still fails, I'm afraid you may need to do a fresh install (wipe the device fully, before making a fresh install of your ROM.). This should fix your problem, though you loose your data. Unfortunately, thats one of the risks of modifying our devices. One that I had to learn the hard way (by hard, I mean hard brick).
At any rate, hope this helps.
Thanks for the quick reply guys!
I have not made a backup of my files.
So now I'm downloading slimkat for a little change..
(also is there a way to create a backup of my files with TWRP and restore them on Slimkat?)
[UPDATE]
I wiped cache / dalvik and then install the Slimkat ROM but the same problem persists, then I did a factory reset from TWRP
and then install the ROM, but still the same
Is there any way to unroot your device from the PC?

I don't have my tablet with me to check for you, however, I am pretty sure I found a file explorer within TWRP. Perhaps you may be able to copy from there. Explore the tool abit its quite user friendly and well made. Otherwise, you can make a nandroid backup to create a full backup of your system and try to extract from PC via WinRAR (if the backup is in tar), or some explorer app... see below for details:

Thanks for the tip, I'm sure it will help me in a future failure!
I have already done everything you said without succeeding anything ,so I'm trying to un-brick it with LG's support tool
and I can not get it to recognize my connected Gpad, so I put manually the model and serial number but still it can't see any connected devices...
Now I'm 100% stuck :/

sorry for what happened. have you tried to wipe all data, and all cache then try to do a fresh rom installation? I am not sure why LG cannot see your device. But a wild guess is its something about your recovery because its no longer stock perhaps???
if you can reach recovery, you should be able to fix the issue by wiping all the data (except external SD), wiping all cache (including dalvik), then install your custom ROM. Have happened to me already although different cause from yours but I was still able to restore it although I did loose all my data. But as I said before, its the price to pay for tinkering with our devices.
Hello guys,
Same problem for me, Stock 4.4.2 with TWRP, the OTA update make my GPad boot only on TWRP, no way to get my system back.
I try this one : http://forum.xda-developers.com/showthread.php?t=2772902
Successful My GPad is booting correctly on Android !
Damn!! I read to late your answer, I install a couple of minutes ago the complete stock 4.4.2 V50020d from LG's support tool.
In a previous post I said I was stuck but not really.. I forgot that I have to press volume + and volume - while connectiong the USB cable to enter download mode
But everyone having the same problem with me should really give a try to what JaymZ37 said above.
Peace to everyone and thanks for your replies!

[Q] Help! - Rooted Zenfone 2 (ZE551ML) bricked after OTA accidently

followed a tutorial (Cnncted's youtube clip - How to root the ASUS ZenFone 2 ) to root
Accidentally (very stupid) pressed the update option when an OTA update showed up yesterday (Jul 8 2015), and after that the phone won't start properly - stopped at in search of incredible...
No luck with trying to boot into recovery mode (power + volume up). It just vibrates once and the screen is black. Trying to flash recovery image with ADB and flashtool etc, but the MTP usb connection failed. If I connect it to the PC using the USB cable and then press the power button to turn it on (stuck in that ..."incredible" screen), device manager shows the Z200AD name with a yellow exclamation mark beside, and Asus ZenUI software will automatically start. But it's not really recognized by the PC.
So...if you have any suggestions for me to try, please let me know and that would be greatly appreciated!

p.s. This is a US version, so the it's the WW sku?
Same problem here. I have a rooted 551ML and on July 6th I received an OTA update. I installed it and I'm stuck in boot loop. I have hundreds of family pictures in the internal memory.
The good news is that I have access to boot loader and recovery.
I could not find any custom recovery for Zenfone 2. They are not out yet, right? Is there any way to copy the internal memory of the phone (that doesnt load the OS) to the SD card? Or to paste a file img.boot taken from a downloaded official rom and copy it over the corrupted one on the phone's memory?
If you can access the bootloader, you can do this:
http://forum.xda-developers.com/zenfone2/general/guide-to-apply-ota-bootloop-rooted-zf2-t3127835
Btw, there is a custom recovery out there (TWRP, check the Development section), but you will need an unlocked bootloader to use it in your state (I think).
US version is the WW SKU btw. Hope this helps.

Joel, thanks a lot! I will give it a try.
fingers and toes crossed...
I faced this problem too. All I did was to flash the boot.img of my version using fastboot,
Then I flashed the firmware, without factory reset I started the phone.
I was continiously getting an error "com.android.process has stopped". Ignoring that, I just backed up my whole data. Did a factory reset. Updated
Boom!! Everything was normal... I hope this helps
Just a quick update - followed the method in the link that Joel referred to, and everything worked beautifully. I did get two error messages like “the contact stopped working..." “The process android.process.acore has stopped working.” I fixed this problem by clearing the data/cache from the "contact" app, and that did the trick without a factory reset etc.
I unrooted the device using SuperSU. The fastboot screen, however, still shows a random serial number 0123456789ABCDEF. Is there a way to revert it back to the real one? I do see the real one from settings - about - status.

actually i rooted my zenfone 2 and there was an OTA and i tried to install it without un-rooting my phone. the phone would not turn on and it gets stuck in the boot animation.
the phone wasn't detected by the ADB in my pc so i thought of installing some custom recovery, thought that could help.
i tried installing TWRP but i did not unlock the bootloader and now i am not able to enter in recovery mode either, everytime i try to get in the recovery modethe phone restarts and goes to fastboot mode.
please help.

I was having a similar issue where adb wouldn't recognize my phone but fastboot was detecting it. What I ended up doing was grabbing the latest stock firmware zip from asus, transferring it to my external sd card via adapter and renamed it to MOFD_SDUPDATE.zip. Then go into fastboot (restart with volume up key) and proceed to recovery. It should automatically update your system from there. The only bummer is having to re-configure everything.

stuck on twrp

i bricked my moto z play. i somehow after many days got twrp on the phone. since the phone is encrypted i had many issues. anyway got it installed. my system as far as i could tell did not exist. i put sept.zip on a flash drive and connected it and it was there under usb otg. so i installed it. the fie appears to be on the system. (i saw it in the files twrp has). but i cannot get it to work. i reboot it. and back to twrp. PLEASE HELP!!!!
I think you need to flash the official software through fastboot and get back to stock Nougat somehow. Try booting into fastboot iff you can do that its not bricked. Bricked means when the phone is off and doesnt respongd or switch on at all.
Iff. you can get into fastboot you can reinstall the official nougat software and there are guides somewhere on this forum how to do that.
You have twrp, download and install the rom from here https://forum.xda-developers.com/moto-z-play/development/rom-nov-patch-npns26-118-22-2-8-t3717037
You'll lose everything on your phone, but if it's not booting now anyway....

Usually it is not necessary to lose anything.
First: use twrp to do backup of data. Don't forget data/media which is not included, there are your photos.
Second: flash the ROM you want, but omit the command "erase userdata". Then your data should (!) survive.

2017 LG G4 Stuck in Boot Loop?

I unlocked an H812 (2017 version... serial starts with 702) several months ago and successfully flashed a stock Nougat ROM. Everything was working great until now. This past week, it randomly started shutting down. Yesterday, it got to the point where I could no longer boot into the OS. I think I got to the unlock screen once, and then it shut off. Now it simply boot loops. There is no SD card in the phone. I couldn't figure out how to get into Safe Mode from TWRP, so I did a factory reset. Still boot loop. I then did a factory reset + wiped the internal drive, and then reinstalled Stock N ROM. Still boot looped. Tried reinstalling the ROM again. Still in a boot loop. I know LG G4 has hardware issues. However, I can boot into TWRP just fine, the temperature doesn't look crazy at all, and it can stay in TWRP indefinitely without shutting down.
Something I noticed after wiping the internal drive is that when I'm finished installing N stock, it says it's successful, but when I checked the File Manager to look in the internal SD card, it still shows it as blank (with the exception of a TWRP folder). Is this normal? Isn't the operating system supposed to be installed on this? Why is it telling me that it's finished installing, and yet nothing is there. For fun, I tried booting up, and I'm still in a boot loop. But I assume it's because I have no OS? Or does the internal sd populate with files upon bootup?
I also used used fastboot and flashed the 4 core image (H811 because GPT compatibility said H811). And I also flashed the 4 core TWRP. I tried installing the stock N again, and file manager still shows no files or folders on internal sd except for TWRP folder. Phone still stuck in boot loop (no OS)?
Please, someone help!
I spoke with LG in case it is a motherboard issue, and they said they only replace the 2015 and 2016 model motherboards for free.

I tried installing the stock N again, and file manager still shows no files or folders on internal sd except for TWRP folder. Phone still stuck in boot loop (no OS)?
Please, someone help!
I spoke with LG in case it is a motherboard issue, and they said they only replace the 2015 and 2016 model motherboards for free.

Refer to FAQ # 5a in the UsU unlock thread.
Did you do a clean flash of the rom? If not, wipe cache, dalvik cache, system and most important, format data, before installing the rom again.
I note you did not mention flashing the appropriate gapps for the rom version you're trying to boot up. Maybe an idea if you didn't.
If all else fails, go to IRC (Support / IRC Channel paragraph in the UsU unlock thread OP) and get help directly from steadfasterX.

Yes, I did a clean flash. wiped cache, dalvik cache, system, and also formatted data (yes, formatted, not just wipe). I did not flash gapps because I flashed a stock Nougat ROM (the same one that has been working for months).
I'm really hoping to know whether it's normal for file manager to be blank and not show the Android, data, folders and all that. I want to know if those folders populate upon a successful bootup, or if they're supposed to be there right after the ROM says it's successfully flashed. That way I can tell if there is an issue with the ROM not installing (which if that is the case, of course I can't boot up).
I have been posting on the UsU thread, but steadfasterX said to flash 4 core boot rom and 4 core TWRP. I did that, but still no boot up. And I *think* there is no boot up because I have no operating system? Again, what is supposed to be in file manager after a ROM flash? I asked steadfasterX but have not gotten an answer.

I know when I've clean flashed a rom in TWRP, I show no files in Internal in the USB connection screen. If you didn't get an error indicating no OS installed, I wouldn't worry about that for now.
Again, refer to FAQ #5a. Did you immediately flash the baseband file after the rom flash? Did you re-install the N modem? etc, etc. You may have to re-install the bootloader stack etc. Go through all the steps.
And again, go to IRC if all else fails.

Here's what I've done now at this point. I tried creating and flashing a 2 core boot image via fastboot, and then flashing the 2 core TWRP. Still bootloop.
I flashed the v29a N modem and UsU kernel for my device (H812), then went to TWRP and flashed stock N ROM again. Still bootloop.
I flashed N stock modem again, then baseband package for my model. Still bootloop.
I'm about to extract my MM modem and flash that.
Beyond that, I don't know what to do. I had zero issues with the UsU method originally and everything went fine and has been fine for the last couple of months since I did it.
Well, roadblock again. I attempted to extract modem from the kdz with SALT in FWUL, and after a while, I get a popup window that says: "This KDZ has an ARB of: arb-detect-error" and then it says "Select partition(s) to EXTRACT:"
Except there are no partitions to select. And my only options are "Deselect All" "Extract" and "Abort." If I try "Extract," I get the error, "No partition selected or abortioned by user."
I did make sure I had the latest version of SALT.
Gave up on salt to extract the kdz and turned to Windows. I didn't know what else to do. I was able to extract the .dz, and then extract the modem_32768.bin file. Transferred it to FWUL, renamed it modem_32768.img, and then typed
Code:
fastboot flash modem modem_32768.img
Rebooted, and still have boot loop.
I'm going to investigate this bootloader stack thing (I don't even know what that is). But again, I really don't understand why this all worked fine for a couple of months.

Xiaomi 10T Pro bootloop – possible to save data?

Hi guys,
I have a problem with a Xiaomi 10T Pro. It is in bootloop. The reason for that is unknown (it’s a friend’s phone). The phone settings are basically all standard, meaning the bootloader is locked, stock recovery and stock OS. I can access recovery and fastboot. Safe boot and repair boot out of recovery does nothing. It is just showing the MIUI logo as during the normal boot.
Is there any way to copy the data of the phone (photos would be enough)?
I read about flashing just the boot.img of the firmware but I don’t know which version is running. I am assuming the newest one that come with OTA updates.
I also read that some people wiped the data in recovery (only full wipe possible in stock recovery) and then used some android data recovery software to recover their data.
Not very satisfying options. I would really appreciate a different way. Any ideas?
My first idea was to boot into TWRP but because of the locked bootloader this is not possible.

Note that this may be a hardware problem.
As the bootloader is locked, you can only try to erase the data and see if the phone restarts, which is not certain and then try with recovery software, also not certain.
Or before erase the data, this tool:

Choose "my device is bricked"
Also without warranty.
I have Ur same exact issue xD been like that for months

Thank you for your reply.
I haven’t found a different solution yet so despite the fact that this method is not certain I guess I’ll try it in the next couple of days. Before that I’ll also give this Xiaomi tool a try.
Do you know some good data recovery tools that I could use if the device will boot?

Never had to try to recover my data on a smartphone, sorry.
