[Q] Need some serious help =/

I was in the middle of installing cm7 r2 and I managed to drop my phone and it got shut off. Now when I turn it on it won't get past the first screen, then it resets and brings me to clockworkmod recovery. So I hope there's a way to fix this since I have access to that, but I can't find anything cause really, I don't know what to look for. Any help would be grealy appreciated.

If you can access the bootloader and recovery, then you're most likely fine, and have nothing to worry about. Unless, of course, something was damaged internally (hardware wise) when you dropped it. Do you have any nandroid backups that you made with clockwork recovery? If you do, all you should need to do is restore that backup. I like to do a full wipe (data/factory reset, cache, dalvik cache) before restoring a backup. If you don't have any nandroid backups, then just use clockwork recovery to install the rom. Assuming CM7 rc2 is already on your sd card ( if it's not, just put CM7 and Gapps on your sd card ), go into clockwork recovery, and select wipe. Wipe data/factory reset, wipe cache, wipe dalvik cache (under advanced). Go to 'install zip from sd card', find the CM7 rc2 zip. Select it, and let it flash. Once it completes, go back to install frm sd card, and flash the Gapps. Once that's done, reboot. That *should* get you going again. Good luck.

i would try wipe caches, restoring my back up and make sure everything works, then star the process to install cm7 all over again

I'm pretty sure no hardware was damaged. Sadly I didn't care enough about the stuff I'd lose to make a back up. I did assume I'd be able to put the rom on my sd card but I can't find a single download for cm7...but thanls for the help, I'm glad to know my phone can be saved , now off to find this file...
Found it, will update if phone will work

All the downloads you need should be in the first few posts of this thread. Don't forget about gapps, otherwise you won't have google apps. And once you get everything up and running and stable, I suggest creating a nandroid backup! It only takes about 5-10 minutes, and can save you some real hassles in certain situations. And, since you can't boot into the ROM, you have a couple options to transfer the files to your sd card. 1) Take your sd card out of the phone, and put it in a card reader/adapter, and into your computer. 2) Put it in a different phone to transfer the files 3) the easiest way, is while you're in clockwork recovery, there should be a setting called 'usb ms togge' or something similar to that (i use AR recovery, and that's waht it's called in Ar), and that should mount your sd as a disk drive to your computer. Good luck.
Edit: I took too long, you found it already! Nice. Let us know if it all works out, or if you need more assistance.

Hooray! Phone works again!!! Thanks everyone so much for the quick and helpful replies, I'm impressed by the such friendly community!

[Q] Will Loading a rom wipe data?

Sorry for the noob question, but, yeah will loading a rom wipe my phone?
Also I was wondering if any good overclocking/undervolting roms have been realeased yet for the GNex?

In short, yes, it will. Merely unlocking your bootloader, which is step one if you're on a stock GNex, will cause your phone to be wiped automatically. After that, it's possible to install ROMs without wiping, but it's a bad idea since there's no guarantee that roms A and B are 100% compatible with each other. Every ROM I've seen recommends wiping when you first install it (many will let you upgrade to a newer version of the same ROM without wiping).

I unlocked the bootloader day 1.

on a related note: when you wipe to install a new ROM, will it wipe the entire phone storage (like when you unlocked the bootloader)? when I unlocked my bootloader it wiped everything off including my music, pics, ringtones, etc.... if that happens everytime than i might just stay away from installing new rooms and stay stock w/ root

When you unlock your bootloader, it will wipe your /sdcard/, but when you "wipe data/factory reset" it will leave the contents of the /sdcard/. So you should be able to keep your images and such, but you'll have to reinstall your apps. TitaniumBackup seems to work well enough for this. It backs up to your /sdcard/ but I still copy it to my computer just to be safe.

On my N1, when moving from one rom to another, I wipe Data, Cache, and Dalvik. Would I do the same on my GN and if so would the virtual sd card be left untouched?
If so, that would be great!

I haven't wiped cache or dalvik (dunno if I was supposed to, but so far it doesn't seem to have created any problems) but I believe that doing the above will leave your virtual sdcard untouched. After all, it has to be able to read the new ROM from somewhere, right?

How to do a full wipe

This is my first phone that doesn't have an external SD card and I'm not 100% sure how to properly perform a full wipe it
I know this is a noob question, but I just don't want to brick my phone.
What I Used to Do
Back in the day with my SGS Captivate or SGS2 I just put all my files on my external SD card, then via Android (Astro File Manager) I deleted every folder from the internal SD card, booted into CWM, performed a wipe/factory default, cleared cache, formatted system partition and then installed custom ROM and everything worked fine.
What I Need
I want to be sure that I don't brick it so I'm hoping that someone can give me a step-by-step walk-through of how to install CM 10.1 (or any other ROM i guess) on my phone after completely wiping it of anything on it.
What I've Tried
I used the Galaxy Nexus Toolkit to unlock, root and install CWM but unfortunately when I then installed CM 10.1 via CWM, some leftover files remained from the stock ROM.
Basically, my phone is ridiculously slow/lagging and I'm getting sick of it.
I've tried installing a custom kernel (Franco Kernel), I've set the CPU governor on Performance (1200MHz always) uninstalling any un-needed apps... but my phone is still un-usable.
Sometimes when I install the latest nightly of CM 10.1 I do an update and other times I tried doing a full install where I wipe the Dalvik; neither way helps I still get the ridiculous lag.

The definition of a full wipe:
-wipe data / factory reset
-wipe cache
-wipe dalvik cache
-(optional) format system
Then flash the rom/gapps/kernel.
Maybe you have a "bricked" phone. It has something to do with the emmc chip. How much free storage do you have?
Check it by downloading the app in the screenshot.
If you havent a bricked emmc version, then I suggest returning to stock again, and then root again. ( most clean process , as it restores all the partitions to the stock state.)
Hopefully this helps my friend!
PS: you posted in the wrong forum, don't do it in the future

That's not related to development, read the rules next time.
Try the full wipe zip from Android Revolution HD Rom.

Use the pinned guide for fast boot. Use fast boot format/erase commands for all partitions, and for good measure flash to stock with fast boot also. This is the most surefire way and it hasn't failed me yet.

Thanks for the info, I'll be more careful in the future where I post.
I have the 16GB model and 4GB free right now.
I installed the eMMC Brickbug Check app and it says that my chip is ok (sane).
My phone is definately rooted, so I'm not sure why this app says that root is required for the memory test (clicking it just launches wiki page on rooting).

If you're on 4.2.1 you won't see any CWM backups so get ES File Explorer, give it root access and then go to /data/media/clockworkmod and see what's about. Or boot into CWM and delete some old backups
As for a full wipe, I use this before flashing a new ROM:

It totally forgot about the CWM backups
I'll delete those ASAP
There wasn't a lot in the backups folder but there is about 3.82 GB in the blobs folder in the clockworkmod folder; are those ok to delete?

Flash the newest version of CWM (6.0.2.3) as it doesn't use blobs any more. Delete all old backups and take a new one if you want. Also, check when I added to my last post

Thanks a lot, I'll give that a shot tonight.
I'll update CWM to the latest, then run your super wipe zip followed by the latest CM 10.1.
Thanks a lot for the super wipe zip too.

After wiping and flashing go ahead and run fix permission too.

Thanks guys, my phone is usable again
You guys are awesome.
What I Did
- installed the latest CWM using fastboot
- booted into recovery
- used adb to sideload your super wipe script, then the latest CM 10.1 nightly and then the latest gapps
- fixed permissions via CWM
- restarted my phone to get a very responsive phone again
With my last 2 phones I was spoiled having external SD cards so that i never had to sideload or use fastboot (I let Odin do that part).

[Q] Need help, i can only access twrp recovery mode

I was advised that i needed to update my recovery to twrp from cwm recovery to avoid an issue i got while flashing roms (the contents of my sd card would get pushed down into a subfolder of a newly created set of folders) however when i wiped my phone, as i always used to do with CWM twrp seems to have wiped a lot more, its wiped the existing rom, and all the files on my card, so i cant install a new rom. Basically i only have access to twrp recovery mode, how can i get the rom .zips onto my phone to install them? Id really appreciate any help at all, i had no issues flashing with CWM and i really dont know what to do.

download a rom/gapps and use adb to transfer them to your sdcard.. adb command "adb push file.zip /sdcard/file.zip"..
PS- in twrp wiping data wipes EVERYTHING so when you want to wipe before flashing a rom do a factory reset and DONT wipe data

[Q] Tricky Google Galaxy Nexus Question

Hi all!
I have been a long time lurker and this is my first post. I have a rather confucing question about my Samsung Galaxy Nexus
I am rooted, and was recently running CM10-whatever the latest is
I got sick of it (mainly because of the stupidly slow GPS lock times), so I wan't to switch. Xenon HD seems to be gettinga lot of praise, and stability is what I prize most in a rom, the second being speed.
I have TWRP 2.5 installed.
What I used to do in the past (with previuous phones) When switching roms was to place the rom file and gapps in a neat little folder on my Laptop.
I would then boot the phone into recovery, do a full wipe (when switching to a new rom) and factory data reset, and then wipe data/dalvik just for good measure
Then I would pop my phone into USB storage mode while still in recovery, and just move my Rom and Gapps zips to my phone.
When I did this, I had AmonRa's recovery installed, NOT my current recovery (TWRP)
PROBLEM:
I need to do a factory data reset when switching from CM10 to Xenon, but when I do the factory data reset, it erases the rom and gapps file I was planning on flashing......womp womp. As far as my research tells me, TWRP does not support USB storage mode, and will not let me just use the phone as a USB drive and simply move my rom and gapps zip from my desktop to the phone (like I used to do).
I know that I can use the sideload feature, but I would prefer not too, as I am not so good with ADB terminal, and don't have a lot of free time to re-learn what I have forgot. I essentially just need to know how to get these zip files onto my phone, and perform a factory data reset (without erasing them)
Or else, if I have overlooked some form of USB drive support while in TWRP, please enlighten me!
If anyone could just tell me how they go about avoiding this silly little issue I would greatly appreciate it, thank you!

You should be able to factory wipe without wiping the internal memory that has your ROM and gapps on it. when wiping in twrp, only wipe cache, dalvik cache, and data....that's what a factory wipe does. Don't select internal memory and it won't wipe what's on the internal "SD card"
I haven't used my computer to flash Roms in ages...just download the ROM and gapps to the "SD card"....if factory reset is wiping that then something is wrong with your recovery

Hey don't feel bad.....I don't even think I remember how to use adb anymore

Using adb is just as flashing a ROM through a custom recovery: once you really know how to do it, you'll never forget it .
