Hey folks I'm looking for ideas to unbrick my OPO which is permanently stuck in a boot loop. It all began last Friday while flashing the lastest CM nightly and gapps. The flash executed successfully then entered a boot loop that refuses to be resolved. I've tried formatting and wiping all pertinent partitions including /persistent, fastboot flashing different version stock images, different radios... I don't know what else to try short of j-tag to rectify. Any and all advice appreciated. TIA

Feb. 18th, 2016 Edit:
Well I'm happy to announce that after nearly 5 months of trying different tactics I was finally able to get my handset up and running this weekend.
The technique I used was to first flash the new official Oxygen OS following the directions from the oneplus forums. From there I was able to boot-up for the first time in months, but had no connectivity. I went to settings and saw I had no IMEI showing. Realizing this, I tried using the technique Heisenberg suggested below in this thread, but again I had no success.
Then I tried the instructions in this thread (which I had tried previously with no success) http://forum.xda-developers.com/oneplus-one/general/guide-efs-partitions-how-to-lost-t3307793 and viola! I got my radio back. It took me several attempts to get bluetooth and wifi back working, with rebooting in between, but alas I was able to get all fully functioning again.
Then I re-rooted and reinstalled TWRP (unofficial 3.0), backed up everything (including firmware and EFS partitions), then proceeded to flash the latest CM snapshot, then eventually the latest CM-12.1 unofficial CAF Sultanxda that I'm now happily running!!!
Thanks again to everyone who posted trying to help me get my handset working again. Now I have two fully functioning OPO's and am very happy!!!

You might have a corrupt persist partition. Download this:
https://drive.google.com/file/d/0B98G0KTJwnBFUnJCNldodGs2dE0/view?usp=docslist_api
Then:
Code:
fastboot erase persist
fastboot flash persist persist.img

Thanks it's greatly appreciated. I had tried this earlier with a download from another link, but tried again with your persist.img and unfortunately, it too didn't work.
This scenario that I'm currently experiencing is eerily like a common problem we had with the HD2, where over time and use NAND cells would get "stuck" and go bad. If the bad cells were located in the portion of the NAND allocated for the /system partition an unresolvable boot loop would result. To work around this developers added tools to HD2 recoveries that would allow reordering and resizing partitions so the /system partition would wholly reside in a contiguous healthy part of the NAND.
I'm wondering now if the hundreds of times I've flashed my beloved OPO has taken its toll, and created a similar situation where bad NAND cells now reside within the boundaries of my /system partition?
Anyone familiar or aware of any tools I can use from either recovery or fastboot that would allow checking the integrity of the NAND to determine if this is indeed the cause of my current dilemma or rule it out?
Again, any help or suggestions would be greatly appreciated. TIA

If that is the case it's the first time I've heard of it happening on this device. TWRP may have a feature like that but I'm not sure. Other than that I'm unaware of any tools of this nature.

Thanks again for responding. I'm just at my wit's end with this and out of ideas, which is why I even suggested the hypothesis in my previous post. Fortunately, I have another OPO backup, so I still have a phone, but it too is problematic. Whenever the capacitive buttons are activated I experience phantom touches of the menu button, and usually at the most inopportune time. OPO customer service is nonexistent and have insisted since I received the defective device that my problems are firmware related and refuse to investigate further. Nearly a year later and numerous updates the problem is still unresolved, which is why I took the device out of service and made it my spare.
Now with my daily driver malfunctioning I'm nearly ready to throw in the towel and give up on Oneplus altogether and get another device from a more reputable manufacturer. They've sent me several OP2 invites, that I've declined using. My horrible customer service experience with them and now two faulty devices leads me to never want to purchase their products again, no matter how affordable or feature packed they may be.
Anyhow, as previously posted, if anyone has ideas to resolve my boot loop, please chime in. TIA
Is it possible that my boot looping is being caused by a corrupt iemi partition? If so, I never backed it up, but have the number readily available from the packaging my OPO shipped in. I also have my backup OPO that I'm currently using, is it possible to clone that partition?
Any ideas on how to recover or clone my from my other device would be greatly appreciated. Basically anything to help get my daily driver back up and running would be a heaven send. TIA

A corrupt EFS partition doesn't cause this to happen, the phone will still boot but will have no network because it has no baseband and no IMEI.
Still trying to resovle. I refuse to give up!
I'm still looking for help in resolving this bootloop issue. I refuse to give up as long as there is the slightest hope of getting it back up and working.
Being a longtime Linux user I know that by default there must be some type of logs generated in the boot-up process. I'm thinking that perhaps if I can extract the log(s) and post them maybe someone can point me in the right direction towards resolving this issue. I've noticed that after flashing back the stock recovery there is a section which contains several logs. Which do I need, where do they reside, how can I extract them from my device, and how should I repost (them) here so they can be properly deciphered? TIA
Why don't you hard brick your phone and unbrick it by flashing ColorOS ? Not joking .. You can try that .. anyhow you're facing a soft brick ..
Tried flashing with twrp 2.8.6 build instead of 2.8.7?

I thought about this as a possible solution, but the "hard unbricking guide" only contains solutions to use with various versions of Windows. Unfortunately, I have no access to a Windows computer (at least one that someone would allow me to use for the purpose of unbricking). I run Linux on my laptop and desktop, specifically Gentoo Linux ~AMD64. I haven't run Windows on any of my machines for over a decade. For the extremely rare instances where I need to use a Windows application I run it on WINE in Linux.
If someone knows how to run the ColorOS unbricking procedure on Linux, I'd be happy to try it out.

This device was already running TWRP-2.8.6 prior to getting stuck in the bootloop. Since then I've tried every version above 2.8.4, I've tried Phil's, and CWM and both the CyanogenOS and CM recoveries. All with the same result.
Bumb to bring back up this thread, now that I've resolved my problems. Hopefully it will help someone else who may be having similar issues.
Hello,
As discussed in other threads I have issues updating my 9.5.6 GM57BA rom to 9.5.7 or 9.5.8.
I tried both flashing via local update and through TWRP.
Both fail and only fix is going back to slot B where my actual setup is setting.
Based on that the only explanation that makes sense to me is that something on slot a is causing this mess. Easy way to prove would be to flash on slot b, but I don't want to/can't take the risk right now so I am looking for the way to make an exact copy of my slot B to slot A, and then flash to either of the slots to see if it's working.
Can any one point me to how I can do that?
Thanks

Since posting here, allow time to have your issue/question addressed.
Hey all, I did a bad thing. Please help.
Just wanna start off by saying I'm really stupid and things like this make me not want to modify my device anymore. I recently updated to 10.3.0, and after flashing something in the wrong order, I soft bricked my OP6. Since I wanted to basically start over with Android 10, I decided to just do a full wipe, without reading how to. I wiped all partitions through TWRP (Which I very quickly learned is a stupid thing to do) because that it how I went about installing new ROMs on my old phone. That left me with just the bootloader on my phone and nothing more. So I used fastboot to flash recovery and 10.3.0 and everything was fine, or at least I thought.
Everything has been fine for about a week now, until my phone randomly restarted. Upon reboot, my sim card wasn't reading and whenever I tried going to it's settings, it would say "com.android.phone keeps stopping" and after a bunch of searching around... I learned what an EFS Partition is and I'm pretty sure that bad boy is gone. Putting *#06# in the keypad gives me a MEID number, but no IMEI number.
So my question now is, is there anything I can do? I found a few posts that say you could try flashing ColorOS (but there is only an unofficial port for OP6), one comment I found said to use a program called EFS Professional and flash back to stock, and some others suggested MSM tool? Which I haven't used, so I have no clue what that's about. Does anyone have experience or a suggestion for me, please? Any help is greatly appreciated.
My phone is also completely working right now, apart from sim card use. The sim was also 100% working for about a week, before it randomly rebooted, is that normal? I just want to get my phone back to working order, I'm done with modifying. I feel stupid and defeated lmao, oh man, pls help.

Alright calm down, yes what you have done isn't smart to do but nothing is gonna change that, we can't go back in time.
First of I would start with restoring your device by using the the MSM Download Tool which you can find here --> https://forum.xda-developers.com/oneplus-6/how-to/tool-msmdownloadtool-v4-0-international-t3798892
All you need to know is described in the thread, read it carefully before attempting to restore your device. It will re-lock the bootloader, wipe the internal storage and restore all the partitions on your device. Make sure you made a backup of all your important files which might be stored on your device. If those instructions are still not clear enough you could watch this video which shows how to restore your device, here is a link to that video --> https://www.youtube.com/watch?v=jtc7EhNsfPA&feature=youtu.be
After restoring your device you should check if your device shows it's IMEI number again, if not I can't help you further. I've never used the EFS Professional tool with the OP6. So attempting to restore the IMEI with that tool is on your own risk.
I hope you learn from this experience, you should always make backups of the important partitions of your device before even thinking about modifying the system on your device in any way. This won't change your current situation by saying this but it will be helpful in the future.
Good luck!

Hi, thank you so much for the quick reply. So apparently it was just a problem with xXx NoLimits, I think? I tried uninstalling it right after making the original post and now my sim is working like normal. I'm confused because I don't think I had any settings with NoLimits that should of affected the sim or even storage of my phone. So why would it work fine for a week and just randomly decide to kill itself like that? As you can see in the screenshots, my IMEI was missing and is now back.
But I'm still worried about when I had wiped all partitions, is there something funky going on with the partitions/storage of my device? Is the "EFS Partition" the only partition that can be permanently lost? If I can still make a backup of it, I should definitely do that, and is there anything else I specifically should make sure I have backed up?

No problem!
Strange, sounds like something you configured in your xXx NoLimits config caused some trouble. Maybe you debloated an app that causes this behavior? It would be a guessing game for me.
If I was you I would restore the device using the MSM Download Tool to start clean again. After that I would make a full system backup using TWRP. So in case you do lose the EFS partition or something else you will have something to fall back on.
The EFS partition can indeed be lost but you would really need to badly mess with the system on your device. I've only once experienced a lost IMEI number after a system update on my LG G4 but I could restore it using the EFS Professional tool. The actual EFS partition was still there I think but got corrupted somehow. Luckily I had made a backup of that partition with TWRP but I still needed to write the IMEI number to it manually. You should just always make backups before attempting to modify the system on your device. Lesson learned right?

Thank you so much for this info. May I ask what the best way to actually backup the EFS Partition would be? After a quick google search, a few different apps popped up. But based on your reply, I'm assuming you've done this before, so is there a certain method you would suggest for a noob like myself?
And as far as using the MSM Tool for a complete reset/backup, do you think that would really be necessary? From what I've read, newer versions of TWRP don't even let you delete/backup the EFS Partition, which means it would be unlikely that I even actually touched that partition, right? And my experience was most likely caused by some xXx NoLimits setting then, I'd assume. I think what messed me up when I first upgraded to 10.3.0, was that I accidentally wiped the Vender partition (which I believe is what the recovery is now on?) Which is why I had to flash via fastboot. But still, I would like to backup the EFS Partition just to be assured I won't have this come up in the future. But outside of the EFS Partition, isn't it pretty easy to fix any Partition/Bricks that might occur on the OnePlus 6?
And again, thank you so much for taking the time to respond to a silly goose like me. I've made it this far without damaging ant of my phones but I think it's about time I stop playing with fire and actually read/backup important stuff haha.
Nolimit and random reboot in android 10.0.3? Turn off kernel tweaks in Nolimit profiles, and then flash Nolimit. It will be fine.

I have always used TWRP for making a backup of the EFS Partition, the option to do so is still available in the backup section in TWRP. It is indeed very unlikely you ever touched that partition but as you experienced it isn't hard to mess up the installation of your system so you should definitely back it up just to be sure you could restore it if something goes wrong. If I'm not mistaken the recovery is actually written to the boot partition and not the vendor partition or that has changed since Android 10. But I don't see any reason to ever wipe the vendor partition. You should always carefully read instructions before installing any kind of software so you are sure you are doing it right. And yes, fixing soft bricks on the OP6 isn't hard to do when you know what you are doing. Doing research is very important, by doing so you know what you are doing, how you should do it and you will have a higher chance to fix errors in case things don't turn out to work as they should. Luckily things didn't go very wrong for you but I hope you'll spend some time doing research before you are going to modify the system on your device. It will prevent a lot of trouble. But by making mistakes you will learn to right. Oh and I almost forgot to mention that you should copy your backups to an other device or storage in case your internal storage gets wiped.
It's not a problem to give a helping hand, that's what this place is for. I'm always glad to help those who kindly ask for help. :good:

So I finally had time to sit down and make backups of my device. I made a backup of just the EFS and Modem Partition only and I made another complete backup of everything. This should be all I need right?
And yes, I will keep the backups on my PC and on the flash drive I keep my current rom, recovery, kernel, and magisk on.

I could be wrong, but I don't think I had KernelTweaks on to begin with. I keep reading people are having problems with it, so I think I'll just stop using it. And it wasn't reboots that were the problem, I only had the one reboot. The problem was my phone wasn't recognizing my sim card nor did it give me my IMEI number, which is why I thought I might of messed up the EFS Partition. But thank you for the reply.
I'm about out of options anyone tried using smt download mode on msm tool.? Then restoring efs partitions.? And had any success. I'm getting a sha 256 does not match error on msm tool when trying to download super partition. Op8 verizon bricked.
Just saw the following article from XDA regarding TWRP v3.5 being released. I'm hopeful that this means that for devices that ship with Android 10 that TWRP will be able to decrypt the data partition in order to facilitate a complete backup.
That said, does anyone know how long it typically takes for TWRP to be supported on a new device (i.e. G-Stylus 2021)? Just curious what the norm is. Thanks!
That's a good question. I don't know how long it should take, but after reading the article you linked it seems that successfully porting TWRP to these newer phones will take a lot longer than on the older ones. Hopefully someone's already started working on TWRP 3.5 for the 2021 models, but I haven't heard any actual news on that yet.
I would love to be able to get a full backup of my device in case I really screw something up later on. If I had any level of programming skills I would certainly make an attempt at it myself.

I'd look around on github
THIS is a TEST build for the Moto G stylus XT2115-1 minsk_t
(please mind that i have never done this before and i am at least trying to figure out how to create custom recoveries. i just need a good teacher with a little time. .)
*Touch Screen does not work. OTG mouse necessary.*
(not too sure how to fix this error)
*Mount points were for testing*
(modied fstab files in ramdisk to fix mount points)
*modified ramdisk and split_image from Moto G 9 plus unofficial 3.5.1 twrp*
https://forum.xda-developers.com/t/recovery-unofficial-twrp-for-g9-plus-odessa.4195729/
i tried to put a recovery together for this device but im not sure where i went wrong or what to do next. booting into this recovery works but /vendor and /system_root have denied permissions. when it is flashed within twrp and rebooted to recovery or system the screen says no OS installed press power to power off. If anyone can help me figure this one out i would be greatly appreciative. If you need anything i can pull from my device just let me know. Anyone willing to help work on this recovery and figure out what needed to be fixed i would greatly appreciate it!
*EDIT*
i got /data to back without digest verification. Was not able to try to restore the backup as i got NO OS error when i rebooted to restore.
*EDIT*
i was able to figure out pretty much everything except the touch part of the recovery. it has a novatek_ts (NVT-ts)
not sure what to do to enable the drivers for twrp. any feed back would be great.
*EDIT*
Found the driver. I'll post it here and see what you can do. I'll also work on it as I'm still learning where stuff should go in the recovery. And also seems to b that i cannot access external sd from twrp either.
*EDIT*
resolved sd card issues. mountpoint was incorrect. only thing left to get working is touchscreen and not have to use otg mouse.
updated twrp for minsk_t is in files now.
*EDIT*
I found the proper elements to configure the recovery's touchscreen capabilities. Will be recompiling later on today. After I have tested it I will post the new working TWRP recovery. Thanks everybody.

So this is fully functioning now right? Is there any reason to use this over the OrangeFox recovery that has been posted?
Also, if I did install OrangeFox, and decided I wanted to install this later, would it be as simple as flashing using fastboot from ADB, overtop of OrangeFox? Or would the procedure be a little more complex?
My current OxygenOS is the latest "12" version which after the OTA, OnePlus has strangely removed from their support site. It has some issues I don't like as well as many others who have posted on the OP Community board. The inactive partition is corrupted and I'm not sure what happened except I was rooted and tried to use Magisk protocol to keep root, but I got a bootloop afterwards. I changed the active slot to the old slot and got the new "12" version running. The inactive slot is corrupted and I get a Qualcom error message.
I want to go back to the previous ver "11" or LineageOS 18.1. However, I cannot get anything to allow me to sideload to the inactive partition or any partition. If I use adb while the phone is in normal operation, I get adb to show devices so I know I have a link. However, I cannot do adb sideload from the normal booted phone. So I have to reboot it to recovery where it looses it's connection to the adb command on the PC. It sees the phone but says it is unauthorized. It is a loop where adb works while phone is booted but not when I am in recovery. I have USB debugging set on and have revoked usb debugging and reset the whole scenario many times to see if different sequences might work so that I can do a sideload. Nothing has gotten me past this yet. I have even tried the Oxygen Updater app but OxygenOS system update won't let you install a prior version if you have the current one.
Any suggestions. Thanks

I've tried to sideload OOS 11 using Los recovery, but it doesn't work. And, since OOS recovery doesn't support sideloading I'd say that sideloading isn't an option.
However, using payload dumper and fastbootd may be an option. I would have tried this but I'm on 12 and there's no full install zip. But you're going back to 11 so this is a possibility.
But I wouldn't make these changes in the current working slot - don't break what's working.
I'm also not sure whether to use the OOS recovery for the fastbootd stuff or use one from a custom rom.
As you can gather, I've not done this. So you have to work out the details yourself and be prepared to be a guinea pig for the process.
If you do go down this path I'd be very interested in the outcome.
Of course, you could always use the MSM tool to go back to an older version.
Since there is no TWRP for OP8T and recovery is non-existent on it, how is anyone installing ROMs on this device. I have just jumped from my original purchase of OnePlus One that still works except for the power button (it is current with LineageOS 18.1 and rooted), to the OP8T over a month ago and a lot has changed since the OPO. I have looked up fastbootd but still don't understand the differences. Comments about installing ROMS are made all over this forum but most assume you know how to do it. I have gotten spoiled with TWRP on the OPO and can flash a new ROM in around a minute almost with my eyes closed. This is getting confusing. I successfully rooted this OP8T after I got it and that was a very touchy thing having to jump through a bunch of hoops to get it done. I was surprised that it worked after all the steps that were required. It used to be that there was info on how to do this kind of thing on this forum, but now it seems that most everyone thinks you should already know the basics. Well the basics are part of my problem right now. A and B slots are new to me and I think I understand that but have not seen an explanation of how that all works when loading ROMS. I have a working phone at the moment in the active slot, but the "other" slot is corrupted. I tried to duplicate the active slot to the inactive slot and of course I can't get adb to work.... Isn't anyone else having these issues? I will look into the MSM tool again.
If you know where the info is that I'm looking for is, please give me the links. Thanks

I presume that A and B slots are partitions
Code:
lrwxrwxrwx 1 root root 16 1970-01-03 04:30 /dev/block/bootdevice/by-name/boot_a -> /dev/block/sde11
lrwxrwxrwx 1 root root 16 1970-01-03 04:30 /dev/block/bootdevice/by-name/boot_b -> /dev/block/sde35
So try using MSM tool to restore them or find a copy of that partition from a working phone and flash on yours.
Maybe this can help you as well.

Here's some information that I found helpful:
A/B (Seamless) System Updates | Android Open Source Project

Here's a couple of ways to get one partition to look like another one:
1. The Los pre-installation instructions have instructions on how to sync the partitions. Note: it doesn't sync boot, dtbo, or vbmeta.
2. If you're rooted you can copy one partition to the other using
Code:
dd if=/dev/block/by-name/xxxx_(active-slot) of=/dev/block/by-name/xxxx_(inactive-slot)
For example:
Code:
dd if=/dev/block/by-name/boot_b of=/dev/block/by-name/boot_a
Note that you can find out which is the active slot using getprop ro.boot.slot_suffix
I've written a shell script based on the Los zip in 1. (see attachment) that will do all partitions - use at your own risk. Don't run it unless you understand what it's doing.
