[Q] Urgent - Boot loop and unable to restore to stock.

Alright guys, I've got a question. I have my brothers nexus s that has had CM9 A11 on it and we decided to move to the latest CM9. Long story short, I am no longer able to boot the phone up, but can only access CWM Recovery and Bootloader/Fastboot mode. Trying to boot results in a bootloop. I need help getting this thing back to stock however I can. I've tried to flash recovery.img via fastboot but cannot get my computer to recognize the phone in order to do what I need. He would like his phone back ASAP and I hate to tell him its bricked for a few days. Thanks!

Download full OTA ROM from the link in my signature. Boot into CWM, mount USB storage, and transfer the file to SD card. Flash it. Done.
Just make sure you download the correct ROM for your phone model.

Video on that page will show you how to install drivers on a windows-based machine to recognise the phone for fastboot, and provide files to do so.
Also, can't you go into CWM --> mounts and storage --> mount usb storage (while plugged into the computer) then copy over any files you need, then flash through recovery.

I forgot to mention that I am getting this when trying to format cache:
E:Can't find misc
E:failed to find "cache" partition to mount at "/cache"
E:Can't mount /cache/recovery/command
E:Can't find misc
E:failed to find "cache" partition to mount at "/cache"
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/log
E:failed to find "cache" partition to mount at "/cache"
E:Can't mount /cache/recovery/latest_log
E:Can't open /cache/recovery/latest_log
E:Can't find misc
E:failed to find "cache" partition to mount at "/cache"
I tried to install the OTA update like you said but got the following:
assert failed: write_raw_image("/tmp/boot.img".
"boot")
E:Error in /sdcard/(OTA file name here)
(status 7)
Installation aborted.
Maybe the internal SD card is bad? Any thoughts?

When you get the drivers installed, download the latest 5.0.2.0 CWM from here.

Alright, so I got fastboot to recognize the phone, but am having another problem. It gave me an error when I gave the command to flash the new CWM. I tried to install pdanet for the drivers, and the phone says at the bottom "FASTBOOT STATUS - FAILInvalid Command". I really think something has been corrupted, any ideas on how to fix it/restore it? Thanks for all the help guys.

Fastboot status is not a command.
Fastboot devices is the command you use to test if it sees the device . The serial number will show.

uh oh sounds like someone flashed brickROM V1

error after flashing from Odin

I tried to flash a latest firmware(5800XWJPI and with the apollo_0531.ops) with odin 4.252 after hard reseting, everything was ok but after the rebooting the phone stuck on "--delete App data... delete files, please wait"
how do I get to hard reset again somehow from any recovery? The phone cannot boot. I tried to flash another rom but the problem is the same.

Hold vol up, vol down, home and power button to go into recovery.

it shows me the g3mod kernel non-oc because I have flashed it before just to go to recovery to enter cmd but it was futile...
now stucks on that logo
update: I suceeded in booting into recovery mode which was cwm. I flashed afterwards CyanogenMod 7.2.0-RC3 (Alpha8.2) and the gapps after having wiped everthing but the phone still stucks this time on the gt-5800i (with the black backround) and not the regular cm7 blue logo. So it does not boot again.

any ideas?

^By full rom.tar, I think he meant was to flash any other ROM via Odin (preferably a Stock one!)

ok I flashed zerofill and after that G3MOD-2.5-OC-zImage and then I tried to enter recovery. From there I see many errors like
Code:
E: unknown volume for path [/cache/recovery/log]
E: Can't mount /cache/recovery/log
E: Can't open/cache/recovery/log
E: unknown volume for path [/cache/recovery/last_log]

E: unknown volume for path [/cache/recovery/command]
E: Can't mount /cache/recovery/command
E: Can't open/cache/recovery/command
and maybe more but I cant see them because of the screen
I wiped all and then flashed from zip CyanogenMod 7.2.0-RC3 Alpha8.2 and the Gapps-06-07-12-signed and everything went fine until I reboot. When I reboot, rom is behaving like it does wipe all and everything is from the begining. Plus I see available internal memory 0mb!!! And I cant install anything. Have I combined something wrong? I have 2 gb sd card. I am afraid to reboot cuz I will have to do and setup everything from the start!

lol....do: fire up odin....now...find a fullrom.tar(e.g. Kyrillos rom 9.x...or my Hercolubus rom)...boot in download mode....flash it....when in cwm...wipe data....now reboot.....if u wanna cm7.2 based....i made a full rom for odin flash & i think kyrillos13 did aswell.....

thanks for reply but will this solve the 0 available internal memory?

Search '0kb internal memory'. You will find a thread with a tar file that will fix the issue.

the only closest result was this post here and after I have downloaded a rom with the proper file inside I can't delete all the other files so I keep only the datafs (I use winrar). Unfortunately I couldn't find a thread with the file attached.

you are awesome, I will try it thanks

the 0 internal memory is gone and now says total193, available 179 but still displays error on instaling an apk with the message insufficient internal space. Another thing. To sd card says total space 0.89gb, availabe 0.89gb! (I partitioned 1gb through cwm). These messages on cwm still remain:

and maybe more but I cant see them because of the screen
is this a problem for the phone's functionality? How do I repair it? Does it have to do something with the sd?
At the cyanogen's application settings, the options "use internal storage" cannot be ticked (is grey). any clues?

Plug your sd into your computer and format it
Jokes gets more serious thought, than serious words these days

the problem is not in the card so its useless to format it, I will only lose data.

Formatting is just one of the troubleshoot. If you're worried about losing data just back up on your pc then format it.

this problem can be related to fried emmc chip

Unable to install ROMS or boot, suspect faulty internal memory

Hi.
First post in the forum.
Just bought myself a brand new Lenovo A830, seems pretty new as there are very few custom roms out there.
It also doesn't help that this is a Chinese model and I can't seem to find support for it anywhere.
I got it delivered from etotalk.com with etotalk's own rom installed, and immediately started searching for custom roms.
Reason for this was faulty English, force close etotalk tools and Chinese info/submenues.
After trying out a few different roms, I've somehow gotten to a point where the internal memory is unavailable.
I think that one of the roms I installed switched the internal and the external memories, because I noticed a bunch of system
folders on the external sd. After that I wiped and formatted everything I could find from CWM 6.0.3.0, and after this, I'm unable
to install or mount anything. I hope this is possible to resolve without involving the external sd into the puzzle, because really, it seems to me
that I've managed to screw up the internal partitions.
Now, when I startup CWM, I instantly get the following messages:
E:Can't mount /cache/recovery/command
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/log
E:Can't mount /cache/recovery/last_log
E:Can't open /cache/recovery/last_log

Click to collapse
I tried to recreate the partition table, using this tutorial:
http://forum.xda-developers.com/showthread.php?t=1158377
I was able to complete the tutorial, but it was not successful. Meaning I was able to create all of the partitions, but still have issues.
I've tried installing these roms:
http://www.needrom.com/mobile/lenovo-a830-5/
(worked installing before, got it up and running, then started messing around again)
and this
http://www.needrom.com/mobile/lenovo-a820-12/
(was also able to install, but showed some nasty "washout" stripes on the screen, which Is why I started messing around again)
and this
http://www.needrom.com/mobile/lenovo-a830/
(was not able to install this one, didn't try it before the mounting issues started.
When I try to mount /sdcard storage now, I get "Error mounting /sdcard!"
Same for /sd-ext.
Also, the internal sd card shows up with "no media" now when mounting usb to PC.
So, the only thing I'm able to do on this phone now is to enter CWMR.
I've searched for days now on several forums, I'm desperate. Please help me!!

[Q] CWM6.0.5.0:Error mounting /data while making a backup onSGS2 in bootloop withCM11

Okay, so this happened out of nowhere. My phone was perfectly fine and when I wanted to check for new messages/notifications etc he couldn't turn on. So I powered him up and he was stuck in a bootloop. I said, okay, it's not the first time. I immediately went to backup and restore option to make backup of whole system because data of some apps is valuable to me. I selected the option to backup it on external memory card. It backed up the boot image, recovery image, system partition and when it comes to data partition it restarts or show err on /data partition. I tried changing the default file formats, without success.
So, is there a way to make backup of that partition(maybe installing another cwm?) and how?
Additional info: I tried making backups on both partitions and nothing. On internal SD I have ~3300mb free and on external SD I have ~2500mb free. The reason I am using CWM c6.0.5.0 is that none of the earlier versions don't support Kit Kat based systems. Another thing is that if I select 'mount USB device' option I can see both, the internal and the external SD card on my pc. Perhaps, there is a way to recover /data from that option?
Also, when I enter the CWM at the bottom of the screen it says this:
CWM-based Recovery v6.0.5.0
Swipe up/down to change selections.
Swipe to the right for enter.
Swipe to the left for back.
E:Can't mount /cache/recovery/command
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/log
E:Can't mount /cache recovery/last_log
E:Can't open /cache/recovery/last_log
E:Can't mount /cache/recovery/last_install
E:Can't open /cache/recovery/last_install
One more question: Can I install older version of CWM, the one that I am sure it is working(because I was using it, that's how I know)?

Updating this: motherboard was dead. So, if you are getting these errors your mobo is probably dead, specifically emmc chip. It can be soldered out and resoldered if you find replacement but its not an easy and cheap procedure.
