Rooted 6p and while installing custom rom reset to factory settings

hi this is the first device ive ever rooted and so while flashing a rom and trying to get it to work i unistalled the os completely. now my nexus 6p wont go past the google white logo. Is there any way to solve this? I do have TWRP recovery installed and my desktop os is mac. ( if that is required) . any help would be appreciated as this is my primary device and i really need it to work

Install Android File Transfer from the following link;
https://www.android.com/filetransfer/
This app will run automatically as soon as you attach your device to mac.
I believe your internal memory will appear while in twrp recovery. Copy your desired rom to internal memory and flash it.

Nexus 6p with Android 7.0 in bootloop cannot access recovery

Hi Guys,
I'm Kinda new about making a new thread, so if anything's wrong let me know.
Just last evening my nexus 6p (on Android 7.0 official) got into a boot loop from a normal state. It just boots & right after when the white google logo transforms into 4 round object, it just reboots (it takes about 3-5 secs). I can access the boot loader but was unable to access to recovery from there as that takes it to bootloop again. I've tried flashing it, but since i had already updated to Nougat official version & the official image for 6p is yet to come, i tried with some earlier version of Marshmallow. but that failed as well. can it be that i need to select the right version of factory image as i really do not remember my old marshmallow versions anymore.
It seems i'm out of options right now. :crying:
Any advice guys??
TIA

Found this on Nexus 6p help forum. Haven't tried it though so I'm unable to confirm if it works or not.

@sirluigi, this EXACT thing just happened to me ..
stock nougat, only bootloader unlocked ((( and since I've got no access to recovery and no Nougat image, I don't know what to do next
minicoop7, unfortunately, for that guide I need to go into recovery mode

Have you tried using fastboot to temp boot to recovery?

fastboot boot twrp-3.0.2-1-angler.img
downloading 'boot.img'...
OKAY [ 0.409s]
booting...
OKAY [ 0.680s]
finished. total time: 1.097s

same behavior, nothing but a bootloop
I'm dowloading an official MM image, just to get the stock recovery and see if I can temp boot in it
edit: not possible, I even tried to flash twrp, I tried flashing stock recovery from MTC20F.. tried to temp boot in both, all with no luck and with phone constantly alternating between the "Your device cannot be checked for corruption" screen and the white Google screen with the open lock.

Guys its very simple, flash the stock mtc20f image first. After that boot it, it wont work but don't worry. Onece it bootloops go into bootloader and fastboot flash twrp 3.0.2-0. once thats done boot into twrp recovery. Onece in twrp make a backup of the image you just flashed that don't work. Once thats done mount system in recovery. Once mounted plug phone into computer and open the twrp folder you will see on your internal wich will have the backup that you just made. Transfer an old working backup into that folder that way twrp will recognize that backup. Once the backup is in the folder you shoukd see 2 backups in there, your new one that doesn't boot and your old one that does work wich you just put into the twrp folder. Once done go to restore and restore the backup of the working rom you just put in there, make sure to check off all on restore. Once done reboot system and it should boot. This will only work if you have a backup of an old working rom.

OMG I finally got mine to work
I'll note down the exact steps , most of which may or may not be relevant
1) Flashed MTC20F using TWRP 3.0.2-1
2) Booted into recovery and wiped everything and the partitions
- Add - Booted back into twrp 3.0.2-1 and then swiped to allow modifications
3) Then fastboot flashed TWRP 3.0.2-0
4) Restored my backup ( except recovery)
5) Still got stuck in the google screen.
Now the next parts are a bit weird
6) Booted into TWRP, flashed vendor.img from pure nexus rom
7) wiped everything except internal storage
8) Flashed vendor.img, pure nexus rom and gapps and then flashed vendor.img again
9) Rebooted and it worked
Let me know if it worked for you guys or if you need any more help

Unfortunately, this didn't work for me.

I believe you should be fine with just trying to flash an earlier recovery version using fastboot... if you're trying to save your data and then factory flash MM and then restore your data to the phone, you should be able to use fastboot pull and then copy them back once you've got a working device by simple copy from windows.

Can you elaborate the steps pls? also have you had an earlier back up of your phone which i don't have?

Has anyone been able to get this to work without being able to get into TWRP? I can't get into recovery whether it is a temp boot to it, or fastboot flash either version..

I have compiled a list of the 20+ methods from various users in THIS thread. It's the second post.

Stuck in a bootloop still @tr4nqui1i7y but will try your methods as well... Fingers crossed..

So I do not if this may help anyone who as run into this issue but still may want to retrieve their data before formating their data or factory resetting. While running TWRP 3.0.3 and flashing the latest 7.1.1 files for angler. I would sometimes be able to boot into the recovery like 3/10 tries ( from the bootloader menu). My data was encrypted and it woul freeze constantly when trying to decrypt soo i decided once I finally got it to boot again in the recovery menu(TWRP after hours mind you) I let the phone stay idle for a few mins should the cpu would cool down that my battery percentage would drop around 41% and the tried to decrypt data which went tru successfully. I retrieve what I Could and it froze during a process of a nandroid backup and started bootlooping again. I believe the battery percentage may be linked to the early shutdown issues that many user were reported having and the bootloop of death we are experiencing. Hopefully this info may help someone else.

Adb sideload full ROM in TWRP with adb push *file* /sdcard

Wipe everything again and reinstall a full OOS zip found here in the forums. Make sure you install it to both slots, once you flash the full rom zip, flash TWRP again, reboot twrp and then reboot to system. You'll have to set everything up again unfortunately. My advice would be after you make a nandroid, copy it to a PC so that when you go to wipe everything, you can copy everything back and go from there or do what I do and buy a USB Type-C flash drive and when you go to make a backup, just backup to the flash drive. Or worst case use the MSM Download Tool to start fresh. Just make sure if you have the T-Mobile 6T to use the MSM specifically for the T-Mobile version.
I keep all of my important files like ROM's, recovery, Kernels, and backups on a 128gb SanDisk Ultra Fit 3.1 and use a Samsung OTG adapter. They can be had on eBay or Amazon for about $25. 32gb for $10, 64gb for $15-20, and 128gb for $20-25.

Do as Mikex8593 said or just flash the system partition of a fastboot rom
fastboot flash system system.img

I tried to sideload through TWRP and it failed every time I tried "total xfr: 1.00x.
I was thinking that maybe I should flash stock recovery and from stock recovery to flash the whole OOS Rom as i downloaded from OnePlus website?
Also i was looking at this thread " https://forum.xda-developers.com/oneplus-6t/how-to/rom-stock-fastboot-roms-oneplus-6t-t3862516"
and was wondering about the Fastboot roms, can I just flash it through fastboot and get the phone back working, since TWRP not working.
I m a bit newbie in this and learning my way through.
Thank you for your patience

Can you please explain what do you mean by installing it on both slots?
Edit: i Have just discovered the slots on TWRP which is something new to me and googling/trying to understand it.
isn't it possible to flash everything back using fastboot or stock recovery?
TWRP have failed in side-loading the stock rom zip I installed from oneplus website.
Yes, i was thinking of the same, I should get a USB type-C it is a must.
Thank you a lot for your help.

While you're booted into TWRP, if it boots to Slot A, install OOS to A, then change to Slot B and flash OOS to B. PM me if you need help. I'll try and help as best as I can.

I have just decided to go to sleep, and in twrp i tried to click power off. The phone ended up in bootloop... then i tried to boot into bootloader. and then few more minutes the phone just booted in OOS Rom and started the setup process as new Rom.
Which is weird, I don't know what happened.
Also i have lost the TWRP recovery
I m not sure if it is related, to me clicking on slots A - B or so.

That's the point of slots, if your ROM is screwed in active slot and can't boot, at next boot the other slot will be set and tried. If there's a working ROM on it it's good. And if in the other slot no custom recovery is present you lose it
That's why I don't understand why people recommend to flash the same ROM on both slots, it goes on the contrary of the slot philosophy. The only understandable case is when you need to have up to date vendor official partitions before flashing a custom ROM: there the ROM Dev can recommend to flash official OOS twice. But it's not the case till now in the few custom ROM I've seen around

Sounds like you might have been making it too complicated. You can sideload the ROM, or just transfer the ROM to the phone and load it. The phone will be seen by the OS as a MTP device when TWRP is up and running.
When you are in slot A and you install the factory ROM it is automatically installed to slot B and vice versa. You need to immediately install the TWRP recovery to keep TWRP as the ROM will overwrite your recovery with the stock recovery. Then you need to reboot to recovery again, this would put to the opposite slot where your "new" ROM is installed, and let you install Magisk. If you want to update this the original slot just install the ROM and TWRP again. Reboot to recovery again. No need to specify slots, unless you didn't want to change something in the other slot for some reason (like a dual boot or something)
At this point just fast boot the TWRP image and re-run the TWRP installer to get TWRP back and it sounds like you're all set.

Hi, I tried to copy the zip file through MTP but it didn't work, the internal storage on PC looked empty and was not mentioning any size of the storage, and when I try to copy and past a file, the copy process gets stuck on 0% forever.
Sideloading didn't work too. The CMD on PC reached 47% and then gave an error of total xfr:1.00x. when i tried to flash the stock rom zip file from oneplus website.
I had TWRP latest official one, i m not sure if it has issues.
Is there a way to validate that the stock rom files and all are still all working fine? Maybe re-flash the stock rom through stock recovery since TWRP is gone?
Also regarding the slot A and Slot B, i have never flashed anything except root through TWRP. So it could be when i wiped it wiped the empty slot. But the system is back at to zero and setup as new.

Bootloop after flashing TWRP

Hey guys,
i messed up i think, but i hope you can help me out of this...
Today i flashed a SM-G950F with TWRP version 3.3.1-0 using heimdall.
It went without any issues and i can boot into the recovery just fine.
The only reason for this was me wanting to backup the whole phone using adb pull /dev/block/sda.
After i was done with this command i tried rebooting back into the system, but now it is stuck in a bootloop.
The phone turns on, shows the logo, vibrates and the screen turns of again and the cycle repeates.
Does this have anything to do with me flashing the recovery? If so, what can i do now? This is not my phone and i'd like to
prevent any data loss.
For the record:
I messed up, because i did not make an backup of the original recovery since i thought keeping TWRP would be fine. Which was stupid, but what's done is done...
I also cannot easily backup the internal storage, as it is encrypted.
Any help would be highly appreciated.

[PROBLEM] Stuck on Android One logo

Hey!
I installed LineageOs on my Xiaomi Mi A1, everything went okay but when I installed the Gapps, it got stuck on the LineageOs logo. The volume button wasn't working right, yet somehow, I manage to enter TWRP and wipe that OS and restore the backup with the original Android One. But when I boot it, it got stuck on Android logo, unable to enter fastboot, TWRP or hard reset because of the volume button not working.
I don't know what else to do, to be honest...
p.d.: I'm new here, sorry if this is not the right section to ask.

Are you 100% sure that you have chosen right version of GApps? because i never had any issues with GApps causing boot loop. BTW what lineage os version 16 or 17 ?
I never had any luck restoring stock rom backup via TWRP either i have no idea why whenever i restore it will stuck on androidone logo.

I chose Android 10 GApps since I installed LineageOS 17. I thought it was the right version.
So TWRP can't be used for stock rom? I didn't know, maybe that's what got me stuck on Android One logo.
Any idea on how to get out from that loop? ?

Dont worry bootloop is not a problem download pixel experience it include gapps boot ur phone to twrp copy rom into internal or sd card Wipe system , data , cache and install the rom ..
TWRP should backup and restore stock image but i think there is something with this phone which wont let twrp to apply system restore i have done it 10 times and i failed everytime.
Edit: do let me know how it goes:good:

Definitely I'll try Pixel Experience! Seems like a good choice. I still need to figure out how to enter Fastboot or TWRP without the volume button.
