Stuck on one plus 6 fastboot screen - OnePlus 6 Questions & Answers

Hi guys,
I was trying to switch OS in my oneplus 6 and accidentally did something. All i can see now is fastboot mode screen. need help restoring.

i got same problem today when switching from Open beta 2 . something is broke with ob2 i think . anyway download latest rom from this link
https://forum.xda-developers.com/oneplus-6/how-to/rom-stock-fastboot-roms-oneplus-6-t3796665
use flash-all-partitions-fastboot.bat to get your phone back . beware it format all partitions .

i did the same at a point, fixed it by fastbooting twrp and started flashing all over again
edit: actually this might've worked only because i was running a custom rom with usb-debugging enabled by default

Moto G 1st Gen XT1033 Boot Loop on Stock Lollipop

My Moto G (XT1033) 1st Gen with stock lollipop has stuck in a boot loop.
I am still able to go in to recovery mode. Have tried clearing cache, but that didn't seem to work.
I don't have CWM installed it's pure android as stock have installed updates only through OTAs.
Have googled about it and many are stating that a factory reset will solve the issue. But I don't want to lose data in the phone.
Main reason for the boot loop could be App as I use beta versions of Facebook, Whatsapp and Nova launcher from apkmirror.
What can be done to recover data or just get this boot loop fixed?
P.S: My device is not rooted and does not have any CWM or TWRP recovery.
I have got exactly the same issue yesterday itself. It was working fine, even received a call after which it was placed on a table. Picked up a few moments later & it was switched off. After that, whenever i'm trying to turn it on, its stuck on the M Logo - Powered by Android i.e Bootloop.
My phone was full stock and totally untouched as well. There weren't any apps installed from sources apart from Play Store. I'm able to access the stock recovery and tried clearing the cache but no respite. Whenever i try to factory format that, it gives an error of e:/could't mount /cache/recovery/xxxxxxxx errors.
I had read the forums for similar issues and got to know from this thread : http://forum.xda-developers.com/moto-g/help/moto-g-bootup-problem-recovery-mode-t3122492. The issue is cent percent same apart from the fact that i can access stock recovery.
Maybe @ravibhat & @lost101 can help us in this. I'm not worried about getting the data but bringing the phone back to life is more important for me !! Please help.

oh okay mate. I have been googling for such issue but the mostly suggested method is reset that I haven't done (not to lose data). Will wait for a day if I get any solution otherwise will reset it.
Let me know what happened to your phone. Hope it gets fixed soon
okay so here's the update. Was successful to take backup as per http://forum.xda-developers.com/showthread.php?t=2426426
And made factory reset after that but now it is still getting stuck on bootloop with M logo and powered by android screen. :crying:
I gave my phone to the service center guys today for reflashing the firmware. They were unable to do and suggested a motherboard replacement for which i obviously refused as they asked for ~INR 8000 as charges. So will start experimenting with it now and hope so i'm able to bring back to life.
What i'm planning is:
1. Flash Custom Recovery.
2. Wipe entire phone.
3. Flash stock ROM.
Will keep updating if i'm able to manage anything
EDIT : Did everything mentioned above but the phone is having same fate as before @krunalshah68. It gets stuck on the M Logo :crying: The internal memory although is being shown as 5xxx MB in TWRP unlike 0 Mb earlier.
Unlock Bootloader (if not already done) and flash twrp - mfastboot flash recovery twrp.img
Alternatively you can boot into twrp without flashing: mfastboot boot twrp.img
Download twrp: http://forum.xda-developers.com/moto-g/development/recovery-twrp-2-8-2-0-touch-recovery-t2980621
Then via PC, do the following wipe: (requires working ADB setup - google it)

Thank you for you reply mate. :good:
I have somehow managed to backup data by script. but the problem is now even after resetting it is still stuck into bootloop.
But I am a bit confused here in steps.
1) Unlock bootloader
2) Flash custom recovery like TWRP and clear dalvik cache
3) and then flash any custom rom
correct me if I am wrong. I am going to follow these steps. @lost101
Phone started! yeeey!
So heres the update bro @BBThumbHealer.
Unlocked bootloader.
Flashed TWRP.
Cleared cache/dalvik cache/data.
Flashed http://forum.xda-developers.com/moto-g/development/nx-nexus-experience-rom-10-0-3-ambient-t3268555/
And device is working smooth as silk now and that too with Marshmallow !:fingers-crossed:
Let me know your status bro. Hope I could help you in some way
@krunalshah68 : Great to know bro that ur phone is as good as new now .. Many congratulations
As far as mine is concerned, did the following :
1. Unlocked bootloader
2. Flashed TWRP Recovery v3.0.2
3. Using mfastboot, flashed stock 5.0.2 and the phone booted up successfully finally !!
But now here's the catch, the phone once flashed up with a rom boots up fine for a single time only. Within that time frame, every damn thing works fine. Able to browse the net, configure apps & settings , blah blah etc etc ... every single thing. But as soon as i restart the phone, the rom fails to startup. It gets stuck on the boot loop.
Initially i thought the rom might have been corrupt, but then i tried the following roms:
1. Stock 5.1 Optimized as posted by @lost101
2. crDroid CM 13 6.0.1
And again the same fate was met.
And yes, i've been installing the above roms by flashing the zips in twrp. After every flash, cleared dalvik, cache & data.
Maybe the fellow members @lost101 @ravibhat can give some insight what's happening ! :crying :
Hello guys, My phone is stuck on bootloop
I have already rooted device and now it is stuck on bootloop even the Recovery isn't opening. I know I would have to reset the phone with mfastboot but I want my internal storage to be backed up before doing all this Is there anyway to do so? Anyone here can help me out?
@sahil_arora05 : if you are able to access the bootloader mode, with the help of mfastboot, flash the latest version of twrp for moto g (mfastboot flash recovery recoveryfilename.img). After that, connect an otg disk to ur handset, boot into twrp and you'll be able to see all your files in the internal storage using the inbuilt file explorer for twrp. With that you can copy all ur data from the handset to the otg drive.

@sahil_arora05 Use mfastboot. It's been specifically designed for Moto devices as the regular fastboot is reportedly having some issues with Moto mobiles (read this on some XDA post itself)

Hi Guys,
phone : Moto G (XT1033), Falcon
- stuck in bootloop
- able to go to recovery
- unable to flash custom recovery such as twrp or cwm
- as suggested,
1. Unlocked the bootloader successfully, can see code status = 3 in recovery mode
mfastboot oem unlock <CODE>​2. Unable to flash twrp. It writes successfully but shows stock recovery only
mfastboot flash recovery twrp-3.0.2-0-falcon.img​3. so tried booting twrp using with success
mfastboot boot twrp-3.0.2-0-falcon.img​4. cleaned cache, dalvik etc.
5 using twrp, used ADB which enables MTP which let me transfer Android6.0.1_NX_R10.3.3_MotoG2013.zip to internal memory
6 Using twrp to flash ROM - Android6.0.1_NX_R10.3.3_MotoG2013.zip​
It seems it started installing but its been more than one hour and it seems its still doing something.
It has stuck at - "Patching system image unconditionally..."
is this normal? Did I miss anything?
Appreciate help in advance. thank you for your time...

OnePlus one does not go into recovery after updating it

Hello everyone, I'll tell you what happened
First I was in CM13.1, then I flashed to oxygen OS 3.1.4 custom
(When I flash the ROM, without warning me the recovery was updated to the version TWRP 3.0.3-2TugaPower, previously being in a version inferior to 2.8)
After logging in to the new recovery, I noticed that the recovery version was not on the TWRP page, so I decided to flash the most recent version of TWRP (twrp-3.1.1-0-bacon.img), flashe it through Android sdk (Fastboot), everything went well the pc recognized me the OPO in fastboot Mode and flashe the recovery without problems, the problem came when I try to enter the new recovery the OPO does not enter the recovery stays in the OnePlus Logo.
(Before updating the recovery I tried to restate the backup of my previous rom CM13.1 but when I was going to restart it it stays in the OnePlus logo, and when I go to recovery I fixed that in the section of "Mount" system is not checked , Active but still the same, and when I return to recovery is removed.)
I ask you if you can give me ideas to be able to have recovery again and revive my OPO plz.

I guess you didn't read the OP of Oxygen Os correctly,he clearly mentioned that this 'Tuga Power Recovery' is patched to work with Oxygen Os's firmware and one should not flash any other recovery.Now,what you can do is this,
https://drive.google.com/file/d/0B-ikULjZZlloNHpOdVBrTzQxZzQ/view?usp=drive_web
> Download This file, install it somewhere and run Revert-2-CM.exe. Make sure you have fastboot drivers installed or it wont work.Avoid using any Antivirus program while doing this as they might give false alarms.After this you'll be restored to TWRP then you can flash any rom you want.The reason due to which you weren't able to find 'TugaPower Recovery' on TWRP page is because this is an Unofficial Recovery.
Question
What does the program do with the OPO?
If you are familiar with fastboot commands, this method should work. Had my OnePlus in the same situation last night messing around with Efidroid. Phone was bootlooping. Efidroid boot menu as well as recovery mode were both inaccessible. I had tried several other things but none worked for me. *CAUTION: this method did ERASE my userdata.* I downloaded a fastboot-able stock full firmware zip, then manually reflashed device. My beloved OnePlus is no longer my daily driver but still my fave device to experiment with so I just used COS 13.1 file. After full reboot, I downloaded and flashed official TWRP. Device is fully functional again, but without OOS installed.

It'll change your firmware and alter your recovery to a functional TWRP.You'll lose Oxygen Os after doing this.Though you can use this anytime when not being able to flash TWRP.
What should i do
Thanks a lot thanks to the method you told me my OPO has recovery again really thanks, but I have a question, I still in the TugaPower recovery, should I flash the stock recovery or the newest version of TWRP?
Because I do not know if flashing again the TWRP will happen the same

I did a mistake (i think) and Know got a kernel error

Hello everyone
So here my problems :
I wanted to put Havoc OS on my OP7Pro and i downloaded the TWRP on the official website. After trying to install TWRP but inevitably fail, i followed a thread on how to install TWRP with magisk and after problems after problems arrived.
I cleaned everything and TWRP didn't detect my internal storage, so i tried to put the official rom via a Fastboot rom (since i didn't have access to debug mode and unable to boot) but the fastboot rom rebooted and Qualcom CrashDump (Kernel Restart).
After that i tried MSMdownload tool but was not able to get past "Param Preload" and after i'm stuck with the Kernel_restart of the Crashdump
OnePlus 7 Pro model : GM1913 (France)
If anyone got a solution i'm in
Hilarious! I did the same thing this morning ........ tring to flash cm17 tho but still same kernel flash crash dump etc
So I did the same as you, tried everything....
I was running 10.3.0 originally but after using "flash factory images" with --- https://forum.xda-developers.com/android/software/tool-tool-one-driversunlocktwrpfactory-t3358711
and choosing 9.5.13, 7pro fastboot zip, everything is booted now and back to normal
folder with 9.5.13 file-------- https://sourceforge.net/projects/fastbootroms/files/OnePlus 7 Pro/
I even tried manually flash all partitions before using the tool but did not stick, kept booting to crash dump
When I tried the all in one tool and 9.5.13 all is well again.
Very funny you have the same issue as me today but I resolved so you should be able to as well - cheers

Great!
However now I am stuck...
When I fastboot boot twrp img I get black screen and nothing happens... so i cant install twrp yet
So I can just re lock bootloader and call it a day and stay on 9 but I like root for Viper at least so I may struggle on.
So I just used the tool instead of doing manual boot / flash twrp. I did the flash recovery and root, choosing Pie twrp and 20.2 magisk options and now working fine.
I am not sure where my error lies but this tool is great LOL..

In that case it would be possible to open the botloader again? If so, try this, it is obvious that you flashed an Android 10 rom ..
step 1: reinstall the twrq maunofrio Q and flash a rom oxygen of android pie the last one if possible 9.0.9 (this only to be able to change twrp, the same will still be in bootlop, but now if you get the twrp of android 9 )
step 2: flashea twrp enchilada 3.3.1-2 img, already in recovery flashea twrp 3.3.1-2.zip and restart in recovery.
step 3: download exactly the rom 34 that would be the rom 9.0.6 I think (OnePlus6Oxygen_22_OTA_032_all_1906251226_0033d1285cf04df0.zip) you flash and do not install anything else you just start the system .. nothing more as long as I stay in bootloop I do that and it has always saved me. pdt, I speak Spanish sorry for my translation
Have you got backup of your EFS partition? If yes you can try use MSM tool and SMT Donwload mode. As password use: te123. It will reflash your phone completely, but there will be no modem, imei, wifi, bluetooth, etc. Don't do that if you didn't backup your modem/efs.
To use SMT Donwload mode you have to click Verify and after that select SMT. After that MSM change border to red. Check also SMT menu in the upper left corner and set checkboxes of all your COM ports in new opened window.
Why not format data. That will fix phone!

Lenovo Tab 4 10 plus 30 second boot loop

How can in get out of this boot loop, any advice, answers, help appreciated?
As background my Lenovo Tab 4 10 plus (stock 7.1 rom) had a failed SD card so I replaced the card and factory reset and thought I would try TWRP, Linageos 17.1 with magisk and relevent gapps - this all worked fine other than a Skype issue. I then found an 18.1 rom and tried that and this is where it seems to have gone wrong I set it up in the same ways as the 17.1 rom but with Andriod 11 gapps to suit, did a factory reset and 30 seocnds in I got the boot loop.
To fix it I tried going back to the 17.1 rom set-up that had worked but this then boot looped even with a full recovery reset. I have gone back to the stock rom backup in TWRP again with a recovery reset same boot loop. I have even used the Lenovo recovery tool to EDL mode flash a newly downloaded stock rom and it's still boot looping. I can only think that the 18.1 andriod 11 rom changed something fundimental but I can't find what?
Further I have another problem, the EDL flash worked but it locked the bootloader, however as I can't get in to Andriod with the boot loops, I can't switch ADB mode on so I can't unlock the bootloader to get TWRP up again.
So is there a way to start ADB without access to develeoper settings maybe through fastboot or recovery which I can get in to? Unlock the bootloader without ADB? Does anyone know why after the 18.1 Andriod 11 based rom, I have this continous boot loop?
I have a tb-x704f wich was totally caught in a boot loop, but I manisched to get back to working stock.
I was running firmware s000056 when I flashed twrp without backing up anything. I thought I never would have to go back to nougat, but standby time on lineage os was just not good for me, as I only use my tablet maybe half an hour a day, and I had to charge several times a week nevertheless.
So I tried to get back to stock and awesome standby time.
It was not easy bootloop after bootloop.
Tried Lenovo rescue and smart assistant multiple times, factory reset before and after flash, without SD card inserted etc, but bootloop.
Tried flashing the rom downloaded from the rescue tool with qfil but same result.
I then tried flashing the files with miflash 2016.08.30.0 still the same rom as I thought it had to be s000056. Miflash stopped halfway with some kind of error.
I then downloaded a stock rom from lenovo-forums.ru http://lenovo-forums.ru/topic/24135-lenovo-tab4-a10-plus-proshivka-tb-x704f_s000037_170703_row_qfil/
from the link in the discussion in the bottom of the site.
I had twrp still so from there I got into terminal and wrote "reboot edl" to get into emergency download mode and then flashed away. I presume that I could just as well had gotten in to edl mode by pressing vol+ and vol- simultaneously and then connected to PC holding those to buttons pressed. When the tablet was finished it was off, so I started going to recovery and wipeed cache and did a factory reset. Then booted and instead of bootloop it showed the Lenovo screen with a progress bar underneath. I successfully booted and took a update and then i am back to stock s000056.
The rom I got from lenovo-forums.ru stated it was only for EU and wi-fi model only. I am in Denmark and my tablet is WiFi only.
I think chances for success is greater using miflash than other tools when recovering from bootloop, but then again I don't know. Maybe I could just have flashed the s000037 rom with qfil or maybe I was just lucky, who knows.
But this what worked for me.
I hope this can help someone as I could not with the help of god find any useful help regarding this problem.

Thanks kind man You helped finish my struggle!
The only thing I want to add is that the ROM from the original link is no longer available, so I found the correct ROM using Google from the original filename here https://firmware247.com/lenovo-tab4-a10-plus-tb-x704f-firmware/
