Safe to completely wipe and reflash? - OnePlus 2 Q&A, Help & Troubleshooting

if I do
fastboot -w
fastboot flash recovery twrp.img
fastboot reboot
then boot into recovery, copy the complete stock zip "OnePlus2Oxygen_14_OTA_011_all_1512111634.zip" via adb and flash that from recovery, will this work?
The -w wipes a lot of partitions that I'm not sure the zip covers - am I wrong?
Edit: my mistake, turns out "fastboot -w" only does userdata and cache partitions. If I wanted to, what would be the best way of wiping and then flashing recovery and going from there?

This is safer

[Q] Possible Brick?

I'm selling my Nexus 7 and I think I got a little click happy while clearing it out.
I had reinstalled 4.3 and then for some reason I formatted the data. Got stuck in a boot loop.
When I try to install the image again I get the following:
Updating partition details...
E:error opening '/data/media'
E:error: no such file or directory
Any help would be appreciated!

All this means is that your userdata partition got all jacked up. It's restored when you boot into a rom, but of course you can't boot into a rom cause something else must have also went awry. So I suggest you wipe everything and start over. Follow along with me, this will be fun!
Boot into fastboot, send fastboot unlock command if your bootloader isn't already unlocked "fastboot oem unlock." Accept on screen. Reboot back into bootloader/fastboot. Issue FASTBOOT ERASE USERDATA, FASTBOOT ERASE RECOVERY, FASTBOOT ERASE CACHE, FASTBOOT ERASE SYSTEM. Then flash TWRP recovery using FASTBOOT FLASH RECOVERY [NAME OF TWRP GROUPER IMG]. Then adb push your rom and gapps back to your tablet using ADB PUSH [FILE] /SDCARD, then flash your rom and enjoy a fresh clean tablet!
That's why I prefixed with 'possible'...
Thanks - I followed this guide later in the evening and got it all up and going again.

Nexus 4 factory rom(4.4, 5.1) bootloop

Hello!
My nexus 4 started to optimize app on each reloading few days ago. At last reload it stucked on "starting apps". I flashed factory 5.1 rom by default guide("run flash-all"). It not helped, starting apps stuck again. I flashed 4.4, it not helped too.
I find few tips.I tried.
(4.4) lock, unlock bootloader, flash
(4.4) flash twrp, change filesystem of cache to fat, return to ext4, flash
(4.4) flash by update without -w
(4.4) erase all particles by fastboot, flash manually each particle
(4.4) flash by update, go to default recovery and do factory reset
it not helped.
what could happen? What I can do?
Sorry for bad english
Boot into fastboot, issue the commands "fastboot erase userdata", "fastboot erase cache", "fastboot flash userdata usedata.img", use volume button to boot into recovery, perform a factory wipe using stock recovery, and reboot.
The userdata.img file needs to be extracted from the stock ROM.
Hope this helps get the phone booted.

Thanks, but did not effective: it stuck on boot animation(flying ovals)
It could be a possible hardware problem in that the memory chip is defective.
Try flashing stock ROM with Nexus Root kit. If that ROM fails to start then there is a likely hardware issue

Nexus only runs with Jelly bean 4.2.2 (downgrade from 5.1.1)

Hi,
I have a Nexus 4 which was flashed with Lollipop 5.1.1.
My problem started when, after letting the battery completely drain and then trying to turn the phone on again, I got stuck on the message "Android is starting... optimizing apps" for days. I tried rebooting and factory format with no success.
I also tried formatting it through TWRP, but I got the message "Unable to mount /cache". After that, I tried flashing older factory images but only got my phone to work with the oldest version of jelly bean available by google developers page (4.2.2). After I got it to work, I tried to OTA update it to 4.3, but the same message "Android is starting ... optimizing apps" came back.
I had no other choice but to fastboot format it and flash it again with 4.2.2.
Any ideas on what could possibly be causing this? I thought it might be some problem in the cache partition but haven't found a way to fix it or if it's even possible to. Apparently everything's working with 4.2.2 but I'd love to go back to 5.1.1!
Thanks in advance!
dont dirty flash the factory image. make a clean factory image flash
After flashing stock KK or LP, are you also flashing userdata.img and then booting into stock recovery to format/wipe data before booting the ROM for the first time?

Haven't tried that, I'll give it a go and post the results here!
I've also noticed the phone isn't receiving any signal and it doesn't display the IMEI anymore..
The lack of an imei is a definite problem. Try flashing the stock LP or KK ROM and check for the imei.

Did a clean factory image flash of Lollipop 5.1.1, booted into twrp recovery (I'm not sure how to go back to stock recovery) to wipe the data and got the following message:
E: UnMount: Unable to find partition for path '/sdcard'
E: Mount: Unable to find partition for path '/sdcard'

MTP Enabled
Formatting Data using make_ext4fs function.
Ypu may need to reboot recovery to be able to use /data again.
Updating partition details...
E: Unable to mount '/cache'

After that I rebooted the phone and it's been stuck on bootloop again since then.
When you flash a stock ROM, did you flash the recovery.img? Sometimes, I find that only stock recovery can properly format the cache. When flashing my Nexus 5 to stock from a custom ROM, I get an error message when I boot into stock recovery that the cache has an invalid format. Once I perform a factory wipe, the cache is properly formatted and wiped.

Yeah, I flashed the images for boot, recovery, system, userdata and cache separately. I'll look up how to get back into stock recovery now and I'll try what you've said!
If recovery.img was flashed, the phone should not have TWRP, it should be a stock recovery. If stock recovery cannot be flashed, this leads to me believe that something is wrong with the memory chip.

I tried it again, flashed everything including recovery, went into stock recovery mode and wiped the data. Apparently its back to being stuck on bootloop
Use fastbot commands to erase cache and userdata. Then use fastboot to flash the userdata.img file, boot directly to recovery, and wipe again.

Did it, still stuck on bootloop... Not sure if it can be somehow related but I got this message when I booted into recovery
The recovery screen looks correct because, after flashing userdata.img, you must format in stock recovery.
I am at a loss as to why 4.2.2 works while kk and LP do not.

Ah, thanks for the help, anyway!
If someone else knows what to do.. The phone is now back to the initial message "android is starting... optimizing apps". Kinda of losing hope now
I've done this to my Nexus 5 once, too.
You basically screwed your cache partition.
Boot into the bootloader. Hook the phone up to your pc and open the command prompt.
Enter these commands:
fastboot erase cache
fastboot format cache
fastboot reboot-bootloader
When successful boot into recovery and the errors should be gone.
You should be able to flash a new rom now.

Okay. Progress
You have probably already nuked all your data. So I would suggest erasing and formatting everything again and then flash the newest factory image.
Enter bootloader again, on your pc do the following:
fastboot erase system
fastboot format system
fastboot erase data
fastboot format data
fastboot reboot-bootloader
Then grab the factory image, open the flash_all.bat file in an text editor (either use windows notepad, or grab notepad++).
You have to "cd" to the directory of your factory image. I would suggest to type "c:" *press enter* then cd *pull the folder that contains the factory image into the command prompt* *press enter*.
If you type "dir" now you should get your factory image directory.
Now just type in every command from the flash_all.bat one by one. Report, if there are any errors.

Okay, got some errors on the way... trying to erase data failed (Remote: partition table doesnt exist), format data failed too (formatting is not supported for filesystem with type ' '.)
Also, on the last command:
.\fastboot -w update .\image-occam-lmy48t.zip
archive does not contain 'boot.sig'
archive does not contain 'recovery.sig'

archive does not contain 'vendor.img'

Device version-bootloader is 'MAKOZ10o'
Update requires 'MAKOZ30f'
Rebooted and its now stuck on google logo
Sorry, you should have typed: (it obviously cannot format something that is not there )
fastboot erase userdata
fastboot format userdata
Have you flashed the bootloader?
Have you rebooted after flashing the bootloader?
fastboot flash bootloader bootloader-mako-makoz30f.img
fastboot reboot-bootloader
Don't forget to also flash the radio.
These "does not contain" errors are normal.

It should be - fastboot flash recovery twrp-3.0.0-0-angler.img
and, fastboot reboot recovery, is not a command under fastboot.
Don't you have a TWRP backup? Why's it matter if it wipes the data?
Im on stock N.
I just want to boot twrp without flashing but it hangs. I am starting to think its a known issue and will be resolved later.

[Q] Android won't boot even after flashing stock ROM

It started acting weirdly after shutting down while it was updating some apps. First, it would only function normally when on the charger (it was really erratic off it, shutting down when turning on the data/wifi).
After one day it got briefly stuck in a bootloop, and afterwards it would just display the Google logo and shutdown (or, if on charger, reaching the "Optmizing apps.." screen, and shutdown).
I attempted a "wipe cache", "Factory Reset", and flashed different stock ROMs using the Skipsoft Toolkit, all for no avail.
Is there anything else that can be done?
I suggest manually flashing each partition, including the userdata.img file. After flashing the userdata.img file, boot directly into recovery from fastboot, factory wipe, reboot. Hopefully, this will allow the phone to boot.

Thanks. I flashed each partition manually, but it then gives mount erros on mount/cache/recovery/log and the boot never ends. These are the steps I took:
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot flash bootloader "name of bootloader"
fastboot reboot-bootloader
fastboot flash radio "name of radio"
fastboot reboot-bootloader
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash cache cache.img
fastboot erase userdata
fastboot flash userdata userdata.img
I also tried directly fastboot -w update "zipfile", but it then shutdowns after booting.
After flashing userdata.img, you boot straight to recovery without trying to boot the rom? For mine phones, it's normal for there to be an cache mount error in recovery. After performing a factory wipe in the stock recovery, everything gets formatted and the phone is able to boot.

This is the same, I posted for N4 which is basically the same as G but G is more detailed. Try it it should format your device, helped me after similar brick issue. Btw. I used NRT instead Skipsoft.
