[Q] How to factory reset without bootloader, help me!!!!! - Nexus 7 Q&A, Help & Troubleshooting

After i flashed Kao Droid, my N7 cant boot to system, it just reset to recovery mod. Althoughi tried to wipe data, cache, davilk ...., but it cant boot to system. I read some forums, but all of them say same way " need to boot to bootloader" . I really scared, i just bought my N7 a few days. Please help me (

If you can boot into recovery, i guess that you already have try to flash again the ROM.
Don´t you make a nandroid backup before? Coz you could try to restore it...
Anyways, it seems that all you need to do is flash a bootloader. Maybe you can do it with the toolkit (i don´t know) or if not, just flash the bootloader using fastboot commands, search in the forum and you´ll find the way

You need the bootloader to use fastboot, if he borked it chances are hes gonna have to exchange/RMA

i dont know how to put a rom file on storage of N7 while i cant boot to system. Can you let me know? Please.
P/s: My English is not good, i'm so sorry

Can you get into the bootloader?

i think you are saying you CAN Boot into recovery.. im going to assume cwm..
once in cwm go into i think advance and then mount usb storage. (im using twrp and kinda cant get in my mind where its at in cwm)
Anyway plug usb to the computer and mount as storage. ADB Should work from within recovery. Then use adb from cmd prompt on your (assuming windows computer ) and push a new rom. to the sdcard. unmount the usb storage and flash the rom.. You might have to reboot- recovery..
if you do not know .how to do the above google how to mount usb from recovery and adb push commands..
There is another post with exact instructions.. myself and several others have done this not thinking and wiping out our data/ media then not having a rom to flash ..
wugs tool kit will also fix this for you . but i recommend doing some research and using adb..
if you are afraid of a cmd prompt . look for qtadb.. its a good place for newbie to start .. it looks kinda like a ftp client..
Good Luck .

hold the power button down for 10-15 seconds, and press volume down at tge same time. that should get you into your bootloader.

Thanks everybody for help me. I will try. If i have other problems i will ask later. Thanks again

[Q] i really ****ed up: Erase EVERYTHING! sd,system...

I wanted to Flash a ROM and i put the .zip files in /sdcard/
in the Recovery mode in "Mounts and Storage" I format everyting that was "Format X" (so i format EVERYTHING)
if you ask why its because im an idiot
I've looking for the tutorials for a solution but i am ****ed up just because i have no way that the PC recognizes the nexus by USB, because i cannot acces to anything, there's no system, no data, nothing...
There is a solution?

Boot it up in bootloader mode and either flash the stock rom manually or use an all in one toolkit to do it for you. As long as bootloader works you are fine.

Port Ubuntu to the OPPO Find 5 and win!

Michael Hall writes about how you can win an OPPO Find 5 by porting Ubuntu Touch to it!
http://mhall119.com/2013/08/win-an-oppo-find-5/
So they're asking:
-developers who don't own the phone to develop for it so they can win one, which is nearly impossible.
-developers who own the phone to develop for it so they can win a second one.
sounds a bit weird.
(Of course winning somthing is always cool, but you get the point)

-True, but during XDA: DevCon we had 3 people without a phone produce images for it, and it's not a one-chance thing, you can resubmit as often as you like.
-How about this, if you already have a Find 5, give me the same of somebody who you think should get this one instead. Could be a friend, or somebody who's work in the XDA community you think should be rewarded.
Despite having three separate developers build images and flash them onto the phone, none were able to boot into Ubuntu Touch.

Oh wow, I didn't know you had already gotten that much working. If you're not going to try for the contest, maybe somebody else can use yours as a stepping-off point and just fix what's currently broken.
Testers needed
OK guys, I've just completed a build, but I don't own the device, so I need testers.
If any of you is willing to give it a shot, here is the link: http://goo.im/devs/Androguide/Ubuntu-Touch/find5/saucy-preinstalled-find5-armhf-2.zip
Please grab a logcat for anything that doesn't work (especially if it does not boot).

I flashed "saucy-preinstalled-find5-armhf-2.zip" now I cant get into recovery I was using TWRP and i know you said "need to flash the Ubuntu base after flashing this build" but since i cant get into recovery I can only get into fastboot mode Do I flash this one via adb?

It shouldn't touch your recovery partition at all, do you mean you can't go to recovery because it doesn't boot?
What does adb reboot recovery do?
Otherwise just fastboot flash recovery recovery.img a TWRP image, but this is pretty weird.
Oh, and when I say flash the Ubuntu base after, you don't need to reboot in between, just flash both zips one after the other, the build first and the ubuntu base afterwards. (Also remember to do a factory reset, wipe dalvik-cache and, optionally, /system

fuqqqq well right now it WONT boot up just stays in the green oppo logo splash screen but....
This is what ive done so far so i can flash the TWRP image back on....I do fastboot flash recovery "here i put the recovery .img" but it doesnt want to flash it.
Then I thought why dont i just flash the other file you told me to flash So I try to do that..
I run fastboot flash recovery saucy-preinstalled-touch-armhf and i get the following error
I get error cannot load ' saucy-preinstalled-touch-armhf''
I even tried it on the recovery .img file but i get
error cannot load 'openrecovery-twrp-2.6.0.0-find5'
What i should of done was what you said, flash one right after the other but I didnt...... I by 2nd nature just wiped dalvik cache and i tapped reboot system. So im kinda stuck right now. Does it help that when I do fastboot devices I can see the random numbers generated by my device? I read on a blog for the oppo find 5 that After entering this command ( fastboot devices ), you’ll see the random numbers appeared in the command prompt. This is to ensure that your device is properly connected.)
ANY help you give me is valued. Thank you sir.

From your error message, you simply didn't add the .img extension to the twrp image
Also, you can't fastboot a zip, don't try.
But, did you try to simply do the following?
Code:
adb reboot recovery
There's absolutely no reason why it would have overwritten your recovery, my guess is you can't reboot to recovery using the button combination.
Anyway, if the above doesn't work, follow these steps to reflash your recovery:
Open a terminal on your pc
Make sure you cd to the directory where your twrp image is
issue the following command:
Code:
fastboot flash recovery openrecovery-twrp-2.6.0.0-find5[COLOR="DarkRed"].img[/COLOR]
Reboot to recovery using:
Code:
adb reboot recovery
Are you on windows or linux?
Okay so I did that I flashed the recovery.img then I rebooted using fastboot reboot
Now i proceed to doing adb reboot recovery but i get
error: device not found
Please excuse me as i am not an elite developer im not a noob nor an expert but It could be that I couldnt get the drivers for the phone installed. I know adam outler on G+ said as quoted
+Franco Colomba I had no such issues with drivers. The only thing was ADB needed an extra USB VID added.

I don't think it's an usb driver issue since you have fastboot working. It's true that we don't have adb access when in fastboot mode.
Follow this guide, it's exactly about your issue and assumes you're on windows: Unbrick the Find 5(Software unbrick via fastboot)

Try this:
Download a CM build
Open it with winrar and extract the boot.img from it
hold shift and do a right-click in the folder where you extracted the boot.img, and select "open a terminal here" (or whatever the header is)
Issue this command
Code:
fastboot flash boot boot.img
Now try again to reboot to recovery using the buttons combination
hurray so i managed to get the phone working by using a script found in that one thread you linked me too.. never the less i managed to get into TWRP and from there i had already made a backup (THANK GOD) and i restored and the phone is up and running perfectly. Now what Im going to do is what you instructed to do first.
1. the build first
2. then the ubuntu base afterwards
with
factory reset, wipe dalvik-cache
i will post back my results wish me luck

I've noticed that the Find 5 is kind of hit-or-miss when trying to get into recovery using the power+volume-down combo. It seems that maybe you need to have it disconnected from USB, and start pressing volume-down very soon after, but not at the same instant, as the power button. Also, it takes a while of looking at the OPPO splash before it gets into recovery.

Yes mhall you are correct. I found a little trick to get it into recovery...well im not sure if its a trick or not but its what helped me get back into recovery after it not booting up. I might make a video about it later. But heres an update:
So i flashed both the build and the preinstalled package and then did factory reset which wipes out cache and dalvik
then i rebooted.
RESUTLS: it stays on the bootscreen aka OPPO GREEN LOGO.
what do you think is the problem now Androguide.fr ?
I did EVERYTHING you told me too

Yeah, Michael Hall reported to me that the build doesn't boot either.
I'm working on a new build using a different toolchain, as with the stock Google TC I had to hack my around -Werror flags and this might be the problem.
I'll post the progress here.

[Q] hours for searching for nothing help plz!

I ****ed up my phone today I did full wipe (formatted internal storage too, so i can't flash any rom in recovery because there is nothing) and now i've been searching hours someone who can help me? In TWRP i can't mount anything to my pc (i do not know why?) AND adb says me "devices not found" or something like that so can't push any zip-file to my phone via adb sideload. Is there any way to reapir my phone? can someone help me? Thanks alot!
There was a bug in a bunch of recent twrp releases that causes adb to not work in recovery. Patched versions have been made, try finding one for your device.
Added:
If you can't find a patched version, flash cwm or philz recovery with fastboot, adb is working on both of those. You just need a rrcovery image and do
"fastboot flash recovery <recovery-file>.img"
In fastboot mode.
let's try it out!

See the edit to my first response. Fastboot is done in fastboot mode, not recovery, so you should be good. You just need the basic .img file of cwm or philz recovery.
If you are on win 7 try this:
http://adbdriver.com/downloads/
(Adb driver installer)
Run it when you turn adb sideload on in G2 and connect it to PC.
If it fails you still can go buy somewhere USB OTG cable (few bucks) and flash ROM from usb stick like me.
It appears that accessing fastboot pn the lg g2 is not so simple. Sorta like samsung phone deal, where a manufacturer download is used instead. From what I gather, recovery might need to be wiped to access fastboot, which you could do from terminal in twrp, but thats risky. Apparently, a lot of people have gotten stuck in fastboot mode. Best bet would be to reflash stock firmware through lg download mode. Also see this thread for a method to return to stock firmware:
http://forum.xda-developers.com/showthread.php?t=2432476
Once you are back to stock, just reroot and flash revovery, etc.
downloadmode should still work. go back to any kdz for your version
also source and versions post next time

TWRP boot loop

Hi, I was switching rom cuz of many errors and I stucked on TWRP. Im able to enter download mode and adb and internal storage via PC. Whenever Im trying to flash new ROM twrp just restarts. I search whole the forum and no one of guide work for me. Additional full wipe and hard reset doesnt remove previous system. When Im connecting to lg mobile flash he says that I have still OptimusROM. Please help me
@edit:
After a few hours I find a simple solution. If u got the same situation like me just lanuch adb via cmd and write "adb reboot fastboot". After u can restore stock with LG flash tool. Just be sure that u have .kdz file in the same direction.

Given what you're saying, I'm guessing you're using at least 1 f2fs partition in the custom rom.
This has caused TWRP to panic and reboot for a few people (myself included) when trying to reformat f2fs partitions. The only way to fix that is like you're doing, or wiping the affected partitions back to EXT4, then going back to f2fs if you REALLY want to use it. The reason that this would cause the reboots on install, is because one of the first things most roms do is format cache.

CWM error cant mount-open cache/recovery

Guys, i just bought an used Nexus 4 and after flashing the cwm recovery and trying to boot in the recovery mode i get a few errors stating:
cant mount cache/recovery
cant open cache/recovery
I notice there are a few topics about this and the solution is to adb push or something, but the adb push command wont work in recovery for me, says device not found and i know my drivers are correct since i can fastboot and do stuff.
I actually got the device running perfectly flashing Chroma via sideload, but cwm wont work! I cant access anything from inside cwm... I also tried twrp and no luck.
I also tried a full original image flash, no luck
Can you please help me with this?
Thanks

when you flashed the factory image it should have brought you back erasing and replacing everything. In fastboot did you flash the bootloader, radio, system partitions (.IMG), recovery partition, and so on.? If not try this steps guide http://forum.xda-developers.com/nexus-4/general/how-to-how-to-flash-factory-image-t2010312/page194 its pretty detailed but it helped me after I wiped everything off my phone trying to learn. If that's a bit too much then try searching for wugfresh nexus toolkit. Both will wipe everything from your nexus then replace it and should get everything going
