I'm selling my HTC One (stock ROM, unlocked) so I wanted to wipe my data, apps and settings. I performed a factory reset/data wipe in CWM and rebooted and it would get stuck at the Verizon logo. I cleared cache, tried again, and got stuck at "Android is updating, Starting apps" for a good 20 minutes. Now it goes back to the Verizon logo.
Does the factory reset not leave the ROM intact? What can I do now just so it'll boot to a clean slate?

Download the stock rooted odexed ROM from here: http://forum.xda-developers.com/showthread.php?t=2485319
After you flash it, wipe data and boot up.
Then flash the latest firmware and stock recovery through Fastboot (also that thread), and do another factory wipe using stock recovery.
Your S-Off / Unlocked status will not be affected by this.

Thanks for your help. Unfortunately, I've been at it for a good 5 hours now and I can't get past the first step.
Using TWRP, I've tried adb push <rom.zip> to /sdcard/, /mnt/sdcard/ and /data/media/ and every time it says it's successful, but the directories show up empty in TWRP. Without a removable SD card, I'm not sure how else I can get the ROM on the phone for flashing. I'm not sure if it's related or not, but everytime I reboot from TWRP, it says my phone isn't rooted. I select "Install" but it occurs again, even though supersu.apk is on the internal storage.
I also tried CWM but couldn't get past "format () expected 5 args, got 4. Installation aborted (Status 7)".
Does anyone have any suggestions on how I can get TWRP to flash the ROM? Thanks.
Try this cmd instead.
Code:
adb push nameofrom.zip /data/media/0/nameofrom.zip

I recently returned my phone to stock in order to reset all the firmware and RIL data. Here is how I did it:
Enter recovery TWRP 2.6.3.4 (if you have 2.6.3.3 you may experience issues)
Boot into recovery, then format Data, System, Cache, and Internal Storage (this will leave the phone with NO ROM installed)
Reboot back into recovery. Answer No to the prompt to root your device.
Once back in recovery, Internal Memory will be available again (if you push the ROM before rebooting, it will not be there afterward)
Push the ROM using adb push ROM.zip /sdcard/ROM.zip (this will take 5-7 minutes for a 1.4GB file)
Flash the ROM in TWRP
Reboot when done, phone should boot up corrrectly
Reboot into Fastboot, push firmware.zip package
Reboot into ROM verify connectivity
Reboot into Fastboot, push stock recovery
Reboot into stock recovery, perform a Factory Reset
Boot into ROM
Once you are up and running on the latest 4.4.2 ROM with stock recovery, boot into Fastboot one last time and push TWRP 2.6.3.4. Your S-Off will not be affected and the new owner will be able to flash any ROMs they like.
If all of the above fails, then try using ADB Sideload from the Advanced menu in TWRP.
You guys are a life saver. TWRP 2.6.3.4 did the trick, it just wasn't available on the TWRP site so I didn't install it in the first place. Flashed the ROM and everything back to normal! Thanks for the help!
FWIW, none of the m7 versions of TWRP would load (stuck at "Entering Bootloader" screen). The Sprint version would load, but wouldn't mount the filesystem properly.

The former, stock. The Sprint TWRP loaded but didn't work right. I ended up finding 2.6.3.4 for VZW m7 on an xda thread, it's not on the TWRP site for some reason. That worked great.

Hi,
I am on CM 10.2 nightly. Everytime I try to install an different ROM on CWM 6.0.27, eg. Android Revolution 22.0, the installation procedure goes fine. During Aroma installer I choose to wipe user data partition and so on. Then after reboot my phone stucks on "samsung galaxy note gt-n7100" screen. Afterwards I have to go back into recovery and have to recover my rom so the phone will boot again. Really strange. Any suggestions why my phone is behaving this way?
Regards, heinzelrumpel

Change the recovery, often Philz 5.15 works best with Aroma installer.

Unfortunately this does not do the trick Still stuck after reboot.
I can't tell you why its happening, but what I've done in the past to get around the issue is to flash a stock rom with Odin, then flash a new recovery before going to another custom rom. If you worry about the Knox warranty bit being set you'll have to find an old 4.1 image somewhere to flash. Since I'm past warranty I don't care anymore.
Good luck!
Wipe data cache dalvik format system etc nstall the new rom reboot and after go again to recovery and factory reset it.

Looks I've managed a soft brick. I've been able to get it back into recovery and I've been able to push stock recovery (and also just tried TRWP). Odin seems to work and the T700 appears to accept the recovery. Following reboot I'm still getting stuck back to the Samsung boot animation but then I'm stuck at the boot screen; nothing past that.
I'm not sure if this should help any, but while in recovery mode the upper corner reads the following:
ODIN MODE
PRODUCT NAME: SM-T700
CURRENT BINARY: Custom (after flashing TRWP, when flashed with stock it said 'Samsung Official')
SYSTEM STATUS: Custom
I would appreciate any assistance and thanks in advance! This is my first soft brick since Eclair!
Have you tried flashing stock firmware with odin? Or restoring your twrp backup?
Firmware, yes. I flashed TRWP to see if I could restore a backup, but after the initial reboot after the TRWP flash the device still returns to the Samsung logo.
Try download mode then restore to stock using Odin and then go into stock recovery and reset then wipe cache and reboot.

I've tried that but perhaps I'm not following the proper set of instructions. Would you point me in the proper direction? I won't be offended by 3 year old instruction sets.
(This is stock recovery)
Reboot your tablet into Recovery Mode
Next, take the following steps using the Recovery Options:
– Wipe data/factory reset
– Wipe cache partition
Back to main menu and reboot using the option reboot system now.
If that doesn't do it then I dunno. I know it helped me after messing around with flashing and whatnot.
I don't even bother doing it anymore. I just root stock and add/remove the stuff I don't want.

I decided to walk away from it for a day and some change. In the meantime that allowed for the battery to run out. It shouldn't have had a bearing on the fix, mostly because - well it just doesn't make sense - but after charging full following the drain it took a firmware flash to stock.
I appreciate the sanity check!
Edit: solution added
problem:
after flashing a rom (in my case OP3lite or FreedomOS) you can't get past the boot logo
you have access to TWRP, so you can restore nandroid or flash flashable stock OxygenOS packages (tutorial here)
solution:
wipe: Dalvik /ART Cache, Cache, Data, System
flash your rom
try to boot (most likely will get stuck at boot logo)
boot into TWRP > Advanced > Fix Contexts, and swipe to Fix Contexts
Reboot
(wait a while, it might take a few minutes till it boots)

hi,
I'm running official OxygenOS 3.1.3.
Rooted (systemless) , TWRP installed.
I don't have any problems on my rom, but everytime I flash a rom I get stuck at the boot logo.
I can just force reboot, goto twrp and restore my nandroid backup, and my phone works fine again.
But I can't flash any rom.
tried this:
Dirty flash OP3Lite rom - stuck at boot logo
wipe and install OP3Lite rom - stuck at boot logo
Restored nandroid backup, factory format, wipe and install OP3Lite rom - stuck at boot logo
wipe and install FreedomOS - stuck at boot logo
Restored nandroid backup, factory format, wipe and install FreedomOS - stuck at boot logo
wipe, Format userdata throught fastboot, install FreedomOS - stuck at boot logo
update to OxygenOS 3.2.1 (flashable zip throught twrp)
wipe and install FreedomOS - stuck at boot logo
Both roms I tried are OxygenOS 3.2.1 stock based, my problem is most likely not due to the rom I want to flash.
Anyone knows a solution for this?
is it possible that systemless root causes this problem?
are you encrypted? that might be the issue.
backup your internal sd data then go to fastboot and fastboot format userdata then flash the rom you want

I never did format my userdata throught fastboot, so I might be encrypted.
I'll try tomorrow and let you know if that was the solution.
@Abaddon I format my userdata throught fastboot (fastboot format userdata), but still roms wont go past the Logo . any other idea?
did you full wipe?
wiped /system too before flashing a rom then u go and flash the rom + gapps if needed
how long was it at the boot logo? no animation correct?
did u advance wipe - data, caches, system instead of factory wipe, try it 3 times
I did a few wipe 3 times, still stuck at logo.
I get stuck on this logo, never reboot, just get stuck there.
I noticed that it does flash the rom, cause if I restore my nanodroid backup layers and adblock is added.
I also get zero error while flashing in twrp.
I fixed it .
did a fill whipe, then flashed feedomOS, then tried to boot, didnt get past the logo, booted into recovery, selected "fix Contexts" and then rebooted, started without any problem .
doesent work for me..!! any help

Please help without a functional TWRP backup and restore - phone is useless. Only everytime mega unbrick guide needs to be repeated with painful reinstall of apps
hello guys. sorry if I'm a bit slow on this topic. I'm using the the op3t A3010 version (not dure whether I'm at the right forum or not lol) Recently I updated my phone to the new 4.1.7, in which I had already rooted the phone before with magisk v12. But right after the update, as usual, the phone will unroot and yes I did root the phone back by using the magisk v13.0 version. But it failed the safety net. So after a few 'research', I installed the superuser just in case that the safety net will work this time. But this is when it all went wrong. The phone did restart back to factory settings, but the phone is not rooted (checked by using the rootchecker app) So again, I'm back to the twrp recovery, clean wipe all the data, with hope that I can start from scratch which is from installing the magisk all over again. But after this step, it stuck at the boot logo for like more than half an hour. Than at this moment, I restart my phone back to recovery mode by long pressing the power button, and when I try to install both the magisk 12 and 13 version, there is a line of error code on the screen. There's a site that says simply go to the advance setting on the twrp interface, check fix contents and ur phone will be as good as new. After done doing that, I'm now stuck with a phone with no os installed and about 38% battery left. Can anyone help me here? This is the only phone that I had :crying: Urgent help needed here guys
Unless your original installation is without storage encryption (no dm-verity) this will happen. So next time install custom rom after flashing OB22 firmware+modem, then boot patch for dm-verity followed with custom rom and gapps then boot without wipe
i have the same problem but with p9 lite : when i tried a flash lineageOS or ResurrectionRemix my phone stucks at boot logo and when i flash the original os my phone works perfectly
sorry for my english

Used the search, used google, couldn't find any concrete answers
I am on Android N - unlocked bootloader - rooted via magisk, One Plus 3.
Could I do the following?
use TWRP to make a Nandroid Backup (System+Data+Boot) of my current set-up
then, manually flash (using twrp) Android O
find out I don't particularly like it
Go back to TWRP and Nandroid Restore back to Android N, as if no update ever happened
Or will there be issues?
Thanks
I do that with freedomos. 2.17(N)>3.1(O)>2.17. I restore nandroid and reflash rom

So I'd restore the nandroid via twrp, and I should be good to go?

There won't be any issue. You are alright with the procedure. Just make sure you use the correct twrp recovery for oreo coz if you use the non compatible recovery then you won't be able to boot into recovery once the oreo is flashed and you are forced to go with the stock recovery
Process I followed when I tried oreo last week
Take nandroid of all options available except system image. (system, data, bootloader, firmware, efs, etc.) on nougat twrp.
Do factory reset(wipe everything except internal storage) then flash oreo twrp image. Perform reboot. (no OS warning on reboot option screen will appear) just ignore it. It will boot to recovery even without the OS.
Once booted back to new recovery(oreo twrp)
Flash oreo stock zip and again flash oreo twrp image and reboot to recovery(this time the device will get stuck with a black screen and white LED). Don't panic, just force reboot the device and go to recovery again to flash magisk/supersu. Reboot to OS
Enjoy oreo
To go back to nougat
Reboot to recovery.
Perform factory reset as mentioned above.
Restore everything except bootloader, cache and dalvik cache
Flash nougat twrp recovery. Reboot to system.
Happy flashing.
Edit : use blu sparks recovery for nougat backup.

Hi, OP here. Thanks for this guide.
Unfortunately, it did not work out for me.
Take nandroid of all options available except system image. (system, data, bootloader, firmware, efs, etc.) on nougat twrp.
Done
Do factory reset(wipe everything except internal storage)
Wiped fine although I got an error of not being able to wipe 'USB-OTG' or whatever it's called. I ignored it and moved on.
then flash oreo twrp image.
I googled oreo twrp image and got an img file with filename "TWRP-Oreo-OnePlus-3-3T". When I installed the img, it asked the options to choose Boot, System, or Recovery - so I chose System.
Then I rebooted and went back to recovery.
Flash oreo stock zip
flash oreo twrp image
Done
reboot to recovery(this time the device will get stuck with a black screen and white LED). Don't panic, just force reboot the device and go to recovery again to flash magisk/supersu.
This is where it ends. I get stuck at the OnePlus loading screen and forced reboot into twrp and flashed magisk. Once I boot up the OS, I get stuck at the OnePlus logo and that's it.
I actually re-did ALL of the steps again (in case I made a mistake) and still, the same issue. No progression.
Once I gave up on Oreo, I decided to go restore my nandroid
Reboot to recovery. Perform factory reset as mentioned above.
Wiped
Restore everything except bootloader, cache and dalvik cache
Here's the issue:
I press Restore (I uncheck both bootloader and cache, but there's no option for a specific dalvik cache- unless I'm not looking hard enough?) and I get the 255 Error.
Flash nougat twrp recovery. Reboot to system.
I tried to ignore that error and flash the twrp recovery.
Rebooted and it took me to fastboot. Regardless of I keep trying to reboot system it won't work.
I actually made two separate nandroid backups (the same 'everything except system image' as you've described) in case one of the backups was corrupted. Both backups ended up with the same error.
I got too tired of all these errors and just found a stock recovery and ROM and flashed it back. Now, all my apps and settings are gone. To be honest, I just want my phone back to where it was with Nougat.
Can anyone assist me?
@maxs8007, Like I said I did that already but nope still same issue. It wouldn't let me do matter what I did.

Buddy from my experience the whole thing too finicky and am thinking just factory reset and stick with stock rom. I wasted so much time already. Everytime I get different error, probably recoveries still not fully compatible with Oreo.

Could you please tell me what error you get on the lock screen? Could you post an image so that I can get a better idea of what's happening with your device? Also could you please confirm which files have you deleted? This time you need to delete 5 files which are related to lock screen setting and those are the only files responsible for lock settings on the device. I'm somewhat confused because I never ran into such issue while I did the oreo thing
If you have decided to flash stock then just make a backup of data partition so that you won't loose your data and you can easily restore it via twrp.

I googled oreo twrp image and got an img file with filename "TWRP-Oreo-OnePlus-3-3T". When I installed the img, it asked the options to choose Boot, System, or Recovery - so I chose System.

I read the entire post and here what I've to say. The above quoted steps is where you went wrong. The recovery needs to to be flashed as a recovery and not as system.
In your case the nougat recovery was never replaced with the oreo recovery because you flashed it as a system. This is where it went wrong. Sorry for the dalvik cache and USB - otg, I didn't mentioned about them. Those are the least important points in flashing though I should have mentioned that already
The next thing you mentioned is you went back to recovery which at that moment was nougat recovery and not oreo recovery. I'll link the modded recovery I used for oreo below
The next thing you did is you flashed oreo zip and again flashed the oreo recovery but as you flashed the recovery as system, the oreo stock rom was automatically replaced with recovery because you flashed it as system and the device didn't boot because there was no android OS to boot up
You got stuck on oneplus boot up screen. (this was going to happen because of the same flashing error at your end).
You were unable to boot back to nougat as well because of the same issue.. Never flash the recovery as system. This won't let you boot the device.
To restore your nandroid backup just follow the steps below
As you confirmed you booted to stock rom with a stock recovery.
Flash nougat twrp via fastboot
Boot back to the twrp recovery and restore the nandroid backup and you are good to go

I'll make a video in my free time to help you guys with the steps that I've followed to flash oreo rom and how i came back to nougat successfully.
Hello @maxs8007
Sorry I didn't have any screen shots of the prompt and finally I was fed up with the whole process and had to switch back to oreo stock rom.
Login prompt I was referring to was standard pin required load android. Black background with only pin entry.
BTW I tried blu twrp recovery oreo version and nougat version.
What's interesting is, after several failed attempts it said I got 10 more tries before phone wiped out but after 10 attempts it started counting backwards from zero, - 1,-2 etc., finally I had to flash stock recovery via fastboot and selected forgot password option which reset my phone.
BTW I have deleted all those files from data/system I found another thread but no dice.
Thank you for trying to help us all.
@maxs8007 followed your steps. Booted to oreo, didn't felt as stable as nougat then booted back to nougat. You saved me. Thanks.

I'm sorry that I was unable to help you. The thing is I never used the pin prompt to load android because I reboot too often to flash things via recovery and its too much of a hassle to enter the pin everytime the device is booted and I think it's too much to a security for a android device when there's already a lock screen present once booted to secure the device.
Please don't put the pin entry to load android next time if you flash stuff regularly. It will save you the hassle of going back to stock rom and recovery when something like this ever happens again. The files which I told you to delete in the image I posted above remove the lock screen protection completely
The login pin at the boot to load android was implemented to avoid unauthorized access to the device in case it gets stolen or lost.

Frankly no clue why deleting those files didn't reset my pins and I even deleted gatekeeper files too.
Maybe these are lock screen key files and android boot prompt stored somewhere else. Not sure though.
