Help flashing ROM? - Nexus 7 Q&A, Help & Troubleshooting

Hey guys! I need some help flasing this ROM on my Nexus 7, [ROM] Eclipse 2.1 Grouper - Build 1 - Welcome to the Dark!! (10/12/12)....
Every single time I try to flash it, it never works. I do the following, I install goomanager and flash TWRP recovery. I install all the necessary things to get it running. I transfer the ROM along with the zip file to flash google apps to the internal storage. I then boot to recovery, wipe/cashe/factory reset/devlik. But then I lose the files and cant flash the ROMs. I just flashed stock google jelly bean. Any suggestion/help with this?

Install Clockworkmod recovery, then make a full wipe and flash the rom

I find it easiest to download directly to my N7 "sd card". I use CWM but reboot to recovery, wipe data and then flash ROM from zip on the "sd card" and then reboot.

So, when I do the factory reset, it'll wipe the internal storage but not the 'sd card'?

Yes, only internal storage

Alright, now how do I get there? I used EZ File Explorer and placed the 2 zip files in the download file. Is that the correct place?

Any location is good, just to be on the sd card

I normally just leave it in the download folder. In order to flash it, you just go into recovery and do your steps. When it asks for a location, just direct it to the folder you placed it in and flash.
p.s. don't forget about wipe

Nevermind! I got it to work! I left it out in the root folder like you guys said and the file was still there after the reset! Flashed ROM to the eclipse ROM! Thanks for all your help! :victory: ^_^

Glad you got it to work, but to answer your question, you wipe first then flash the new rom (so you have a clean slate). You don't want to install over other roms unless maybe if it was a minor update of the same rom.

Jellybean rom and gapps can't be found on Xoom recovery

Hi everyone, I know this is on some thread around here already but I'm kinda new here so,
I tried to flash team EOS jb rom + gapps on my Xoom and they weren't found ..
A message appeared saying , error mounting SD card or backup/path not found or something.
My xoom is rooted with stock rom ics, 4.0.4 and at first I tried flashing using rom manager , and no success..the n manually ..the same.
I can't backup current rom neither flash a new one.. I read about reflashing cwm , and I kinda got lost in there..
I moved the .zip files into the internal memory of the Xoom and the same...I got into recovery mode manually and I followed the procedure and again...no .zip
Files found not even on the internal memory.. as I said I tried mounting SD card, mount system and nothing...same error appeared..
So , I really appreciate any advice or tip or whatever helpful... thanks in advanced and sorry for asking something that many already know..have a good day !!

Which recovery are you using ?
Can you still access external sd from recovery?
Sent from my MZ601 using Tapatalk 2
Yeah, sounds like you're not using CWM recovery.
Follow the steps to install this, and flash via CWM.
I can't access SD card via recovery , it says error: backup path not found.. and error mounting SD card.
But I can access my external SD card using any file explorer , It appears normally .
Idk but , so when I rooted my Xoom I remember have flashed cwm via adb , cause I had to connect my Xoom to the PC and I remember a .zip file called something cwm , and tiamat ....so , should I go again and reflash cwm zip , and if so , which one should I flash again? cause my Xoom is already rooted and unlocked, wouldn't that damage the system?

You won't loose root. You are using the same fast boot commands to unlock your boot loader and install this recovery IMG...
Then this new recovery, flash eos ROM which is per rooted already...

Thanks Dude. As I told you earlier, I received the notification about the update but it was installed and it sent me to recovery mode saying : installation aborted...thanks I'm gonna flash the cwm img..

AOKP rom

So i got my nexus 4 yesterday and Ive always wanted to root an android phone and install a custom rom. So i unlocked the bootloader and rooted it pretty easy. I want to flash AOKP rom. i downloaded the rom file and google apps from their website on the phone. I went into CWM recovery and installed those files from the sd card, and it says its complete. I reboot the device and it just sits on the nexus logo screen. I dont know what i did wrong. Anybody got any ideas
It's normal for it to sit on that screen for about a minute or so.. How long did you give it?

3-4 minutes
make sure you have the correct files for your N4 or "Mako" device and that you did the steps properly.
wipe data/factory reset in recovery
flash ROM
flash Gapps
reboot

yeah im pretty sure i did that all correctly, but ill try again. Also for some reason when i try to boot into recovery sometimes, instead of going into CWM, it shows the android robot open with an exclamation mark on him. Any idea what that is
^
I believe that the stock recovery...
When you first boot cmw, it does not stay permanently afterwards...
You can flash it again by downloading ROM manager??
Or somthing else..
Maybe use adb+fastboot to flash ROM..
Just to try if the files aren't broken.

You can't flash a ROM in fastboot, you can only flash images.
You can flash the recovery image through fastboot.
I would let it sit for more than just 3-4 minutes as well.

Maybe I'm wrong, but I think you have to format /system and format /boot when switching from another rom, otherwise it bootlops.

Unnecessary.
Surprised no one has suggested this already. This happened to me before, go back into recovery and wipe davlik cache

There are two files you have to flash in CWM/TWRP to have it available at any time. You don't even need a computer to install and test it. Be warned, though, it's really not worth it at it's current state.

The flashable zips are in here. I haven't personally tried it yet -- internet in my country is pretty crappy.. download will take a while..

Just to get everything clear, I flash the manta.zip, then the all devices.zip, and it will boot fine? As well can I just get back into twrp after to wipe and restore from nandroid backups?
Thanks in advance for the help

The dev preview installs CWM over TWRP it seems

Flash manta, then flash the armhf, then wipe and you're good to go. That worked for me and didn't mess with my sdcard at all. (obviously it does a 'factory reset' on the device though). Backup with TWRP and you're good to go.

Only if you do it using the Ubuntu install method, where it flashes the .imgs over top. If you install it via CWM/TWRP then it keeps whatever recovery you have on the device.

I flashed them both like you said, but it would just reboot my recovery when about 2/3 the way done with the armhf zip, and i tried just rebooting system but it just boots past google and sits at a black screen. Thinking i might have a bad download but nonetheless it was not a success on my end and im just back on android.
thanks anyways for the help, if anyone else hears of this issue and knows how to solve i would love to know.
Does this OS allow me to run any Ubuntu program? Or is it a different system?

[Q] after "Format data" with twrp i lost my /data/media/ mount

Hi folks,
Yesterday i did some real crap... I switched from cwm to twrp, all fine. Then i wanted to flash cm 10.2 and i choose "Format data" in twrp. After typing "yes" i realizied i wiped EVERYTHING... I lost my cm 10.2 ZIP i just wanted to flash, my nandroids etc... Ok **** happens.
I sideloaded the cm 10.2 ZIP to get a working Android OS again. All seemed fine, except i lost all my data...
But last night i wanted to flash a New kernel and i tried to do a backup first. But now i can only choose "internal storage" With about 1,2 gig free space.
Did i lost my mounting point or something? I can access /sdcard with twrp file manager and i can flash zips from sdcard but i cannot choose sdcard as backup location. Also i cannot choose format sdcard (obviously )
What can i do to fix that? Do i have to flash stock userdata.IMG?
Btw here is my recovery log: recovery.log
Choosing "copy recovery log to SD card" works fine...
Thanks!

Use this in bootloader mode, you will have to do everything all over again: https://developers.google.com/android/nexus/images#occamjwr66v

Thank you! Can i skip recovery.IMG to avoid loosing twrp?
Is there no other way to recover my sdcard "mount"? From what i unterstand is that i deleted my symlink or something like that. I tried fdisk -l in console but i get nothing. I took a look at recovery. / storage.fstab and it seems OK. Maybe there is a wrong / missing Entry?
Thanks

You can remove the recovery from the zip file from where the flash all script is and also remove the name of the recovery in that text file.
Don't worry about that, the flash will fix it anyway.

CWM stuck trying to install ROM

OK. Tried to install CM11 on my phone today. Stupidly tried with ROM manager. The flash failed. I tried to go back to recovery but each time I boot to recovery CWM tries to flash the same ROM. So I couldn't get back into cwm to nandroid restore. Tried re-flashed cwm with Odin but still would try to install the ROM at recovery. Had to flash twrp clear everything re-flash my original ROM and titanium backup restore. Any ideas how I can stop cwm from trying to re-flash the problem ROM if I go back to cwm recovery??

Hi,
What phone variant do you have?
i9505 or i9505G?
Maybe you can find where the recovery script is located that CWM is trying to open? Then delete that file so CWM won't be able to take orders from it.

It's the i9505 but with the Google version of 4.4.2

That's what I was guessing but have no idea where this is stored. It's pretty low level so I'd be surprised if it was file based.

HI,

Install question
Hiya
Does installing a rom from CWM take ages?
I have tried to install a couple now and they seem to stop at the GT-I9505 screen?
I am installing from ext sd-card

Yes - used the wipe option inside CWM
It may have been a problem with the download file - will retry

The recovery script that it maybe opening as to why it keeps installing things.
