Hey all,
My Nexus S i9020a started getting into a bootloop. I went into the stock recovery and performed the wipes (multople times), but it still did the same thing when booting back up. It didn't remove my data either (I can see my widgets on the home screen before it goes into the reboot) even though I did a factory reset which is suppose to wipes out everything.
I decided to try a factory restore with a Google Image, but the two that I tried (4.0.4 and 4.1.2) both make it to the same part and failed. My bootloader is already unlocked (Lock State - Unlocked)
For 4.0.4

Any ideas?
How about
fastboot flash recovery recovery-clockwork-5.0.2.0-crespo.img
and format /system partition via CWM before updating?

Installed 5.0.2.0, did the wipes and even picked fixed permissions, then tried to flash 4.1.2 factory image again but still failed at the same spot
EDIT: Tried with 6.0.2.5 also, did wipes, fix permissions. tried cm10
was able to push it to sd card, but when I selected it from the menu i get
set_perm: some changes failed
E:Error in /sdcard/cm-10.0.0-crespo.zip
(Status 7)
Installation aborted.
Looks like flash drive, system partition or partition table is corrupted.
Not sure if this will help [HOWTO] "Partitioning" your Nexus S using LVM
Does root need to be installed to flash a ROM from clockwork recovery?

No. Root not required to flash ROM. Just CWM.
My Nexus 5 recently had some hardware issue and I requested an RMA. The following error comes up when I try to flash the stock recovery system back. Is it okay if I send the Nexus 5 with TWRP installed?

I hate to be the bearer of bad news, but it appears the flash memory is bad on your N5. See here. As for whether it's okay to send it with TWRP installed...hmm. I dunno. I don't think an eMMC failure could be caused by installing TWRP so it shouldn't be considered your fault, but they might make you pay for the repair because of it.

How did you fare with Google and this issue?
I have a Razr HD (my dad's) he took the newest update last week and now he is stuck at the boot logo.(I have told him to not do it) ADB screen is telling me it is unlocked at stats code 3, (I think a dev edition, he bought it used) now I can't get it to take a recovery to flash stock 4.4.2. I tried this script here (http://forum.xda-developers.com/showthread.php?t=2474393) but it wouldn't restore it to stock and let me use the phone.
Any ideas from the android gurus.

is this a 926 or 925
if 926
use rsd lite and this guide form @SamuriHL http://forum.xda-developers.com/droid-razr-hd/general/fxz-4-4-2-183-46-15-t2873083 i would recommend the full script since you are already unlocked and it was a used phone
if 925
same procedure but with the correct sbf from http://sbf.droid-developers.org/
I did this earlier. Same problem

try this utility. it is a special version to fix certain issues that cant be fixed with fastboot and rsd.
watch the dialog and let me know if any operations fail, or copy and paste the output here for me to see.
i may have to update it for you if a couple specific things fail.
windows or linux?

it wont be a problem, but some parts will fail. im downloading the files now to compare the parts i would like to see work.
either way, try that for now and let me know how it goes. there should be no added danger, the trust zone and partition files are what could fail, neither can be downgraded, so i dont see it making things worse if it doesnt work.
the phone says update gpt-main partition failed then the terminal end is FAILED (remote failure)

@Latheman
ok, they changed the partition table again, not saying the phone is fixable, but this is the best chance i could have wanted to fix it.
its going to take me 1/2 hour to fix the script, and an hour (barring issue) to upload it.
ill send it over as soon as its done, if not tonight, then tomorrow.
Thank-you

no, i was just showing you the new version is built, tested, working and uploading now.
so, when i post it later for you to try, this is pretty much a last resort script. if it doesn't work for you, the phone is likely gone.

I tried it, and no soap, I think this one is a loss . (first one of every phone I have worked on). the BL is still unlocked so if anybody ever comes up with something in the future, or I can put something together I might be able to restore it.
Did you try to flash stock with rsd 6.1.5 and editing xml file, say removing tz line

First, sorry for my english.
I'm not a newbie in rooting, but it's the first time i've got a N5. So, after getting my N5, the phone update to 4.4.4, after to 5.0.1 and after to 5.1.1.
After that, i've flash CWM, but i don't know why but this method give me many error (like the /sdcard cannot be mounted, etc) and i'm in a bootloop. So i've install TWRP, and i've see something weird, it's like all the folder /system, /data, etc cannot be mount because is not there.
So, i'Ve decide to download the factory image 5.1.1 (LMY48B) of the N5, and execute the "flash-all.bat", but it's stock to "writing 'system' ...
