[Q] Can't access /system from recovery ! - Nexus 5 Q&A, Help & Troubleshooting

Hi guys.
I have some problems with my recovery, here is my story.
I was running last TWRP, and while doing an update of my favorite ROM, the installation was stuck at fomatting system... I tried to reboot several times and nothing to do it couldn't work.
So I installed (in a dirty way) CWM to try it. Formatting seemed to work and it's still working (or at least it's written that the operation is done) BUT when I want to update my ROM and when the script needs at the beginning to format system, it's stuck for several minutes. Sometimes it works only after 3 or 4 times (or maybe it's because I don't wait enough) and so then everything works out but I've got a message like "the error was system", can't remember sorry, if you need what is exactly written I'll tell you.
So why should I do ?
Thanks.
Hope you understood me, my english kinda sucks..

I think your best bet at this point would be flashing the factory images and starting fresh. I don't use twrp myself, but for what I've read here, it's best to let it finish what it's doing and not reboot.

Well when it's endless I can't let him finish I guess...
I don't know why system image would change anything because it has nothing to do with recovery. Maybe you meant stock recovery and then put back CWM ?

Up please I need an answer

Same thing happened to me. In fact posted a similar post earlier. I used the nexus recovery tool once to get back to stock and that worked but erased everything on my phone.
Did it one other time successfully flashed one rom and then some thing happened but this time I had a backup in twrp and was able to restore that.
The only thing now is my battery won't charge past 77%.

Yeah that is a great how to but I've already rooted and unlocked phone. I understand how to flash roms, I have at least 10 android devices in my home that I flash roms to.
I know the process, it is the same on most devices. The problem with this one is when you go to flash a new rom it says it can't mount system and gets stuck in endless install.

I had the same issue flashing elemental kernel. After the reboot I couldn't access my SD and my baseband weren't recognised. So I reloaded a nandroid backup but the issue was still present. I have never encountered a so strange problem. Resolved reverting to stock and reflashing elementalx.

Twrp system may not automatically mount. From twrp select mounts and system. Or reboot recovery.

I have already gone back to stock completely and started all over to verify I did everything correct. I got sane results not sure if Tomatot has tried more than once.
Not sure if it makes a difference but my N5 is the t-mobile store version.

Mine is from Google Play. Today I flashed a ROM and before I mounted system. The installation was very long (more than usual i'd say) but it finally worked !

Glad to see yours is working. I was able to flash the stock 4.4.1 but it was still feeling a little wonky. Battery got stuck again this time at 35% so I used nexus tool to return to stock completely but still same issue with battery. I think I'm going to lock it and exchange it at the T mobile store.

TWRP from CWM???

Was gonna give TWRP recovery a try... I am currently using CWM and didn't know if it would be safe to just use the goo app and flash TWRP that way. I have always used CWM and wanted to try something new and just want to be safe when going about it.

I tried it, but I didn't like much. To much switching pages to do things, such as format, erase cashed, and dalvic. But who knows you might just like it.

Yes you can install TWRP any way you like. One recovery will simply overwrite the other. Nothing to worry about.
My only brick
The one time i ever truly bricked a phone after close to 30 times rooting and unlocking boot loaders was with TWRP and this phone. I am talkin complete brick, like qualcom drivers request show up on windows brick, the kind brick that you just throw at a window, because you got no charging light, no vibration, no light what so ever.
Btw i was only flashing a rom
I never touched TWRP after .
Thanks for the input guys..... Gonna stick with CWM for now. Seen a fair amount of negative stuff towards TWRP in the forums and don't want to risk anything.

Seconded.
Used the gooapp to flash twrp and haven't had any problems. In fact I switched over from cwm because while installing liquidsmooth cwm kept giving me error 7. Everything I googled told me it was a problem with my recovery, so switched to twrp and presto
Although watch which version of twrp because I was reading the Cleanrom lite thread and ppl were having issues with the latest twrp at the time of their postings. It was around end of September that they were saying this, I believe.

I used to use cwm and now have been using twrp and have never had a problem. This guy above you can't blame twrp for your brick you don't know if that's what it was. Twrp I like better cause I can move my backup folder and copy it even to another computer. Cwm has the blob folder which you can't see which files belong to which backup so you can't just move one backup you have do do them all

Don't know what you were looking out but CWM is the one where the wipes/format are on different pages. All wipe options in TWRP are on the wipe page right next to each other. Newest version now released.

[Q] Can't seem to get the backup working with CWM

Hi, i'm a noob fresh out of youtube and I have successfully rooted my phone and gotten CWM and the Recovery Image flashed but the problem comes into play when I try to make a backup of my stock rom and my phone reboots into the recovery mode and it gives me the options to
1. reboot
2. reinstall
3. delete user data
4. wipe caches
and it says # Manual Mode #

Hey so I tried to get the custom recovery...am I supposed to delete the old "recovery" file and place the modded one there or am I just supposed to leave it alone? I have the update.zip file in the root of my sdcard but still I tried to boot it into the cwm recovery mode and still no dice.

[Q] I think I broke my nexus 5. :(

Hey everyone,
I am new to the android phone arena and would appreciate some help.
I bought the nexus 5, rooted it and was attempting to flash CyanogenMod 11. I didnt realize I need a windows computer to do and was trying to do it through the phone itself. (i know, i know...terrible, like I said, I'm new)
The phone froze and will not even restore from a factory reset. It is like it is trying to reset from the CyanogenMod ROM (which wasnt installed properly in the first place). I have tried restoring from a backup, but none exists. I tried mounting a flash drive with the stock hammerhead ROM on it, but it will not mount. I am using ClockwordMod Recovery v6.0.4.4.
Can anyone help me?

Ok lets try decrypting this first.
It sounds like you got through the rooting process,and got yourself a custom recovery. Ok
You flashed CM11, but it started to boot loop on you.You tried to revert back to stock, but you failed to make a backup. Now you are stuck since you cant mount the phone as a disk from recovery and restore a working rom.
Is this what is going on?
If so, you still have hope. You can use adb from the boot loader and push the stock firmware back on.
Follow this thread and start over from the beginning.

Yes, Un-root, go back to stock and try this again. Next time, make a backup before Flashing like mad.

[SOLVED] Did I brick?

Hey everyone,
So I think I may have done something strange and i'm not sure how to fix it. Long story short, screen cracked, so I bought a new one and I used TWRP to backup my original phone. So now, i'm just trying to unlock and root, you know, the usual. BTW, I tried using ABD/Fastboot, which I never typically do, but I heard it was more efficient and whatnot so I thought I try. I think the unlocking of the bootloader went well. And I even think I flashed recovery properly. But when I tried to access recovery, it prompted me for a password.
I read on the TWRP site I was supposed to let the phone boot as normal before accessing recovery. Oops. So I tried formatting all the data on the phone and no I have no OS or any files to recover from and adb push keeps giving me "Device not found" and now I don't know what to do.
Help?
EDIT: In case anyone has this issue searching threads, I just used Wug Toolkit to flash everything back to stock and then used the same Toolkit to unlock and root. TWRP isn't going to recognize a backup from a different phone. To my understanding, there is a way around that, but I didn't look into it. Oh, and apparently, don't flash the EFS partition lol

Oh, that reminds me, TWRP wasn't able to mount any of the directories, it seems. I think it can, now, but I remember seeing those errors in the log before I wiped everything. Thanks for that suggestion, i'll give it a shot.

OK!
So, I used the Wug toolkit to basically flash everything to stock, and then root it. I installed TWRP using the app and I tried using the app to restore from my earlier back up. So, it boots into recovery but nothing happened. Looking at the log, it says the TWRP isn't able to locate the files. Trying to just restore from recovery isn't helpful because when I hit "Restore" nothing pops up. As if the SDCard partition isn't being accessed. I can't see any of the files in any directory. Anyone have any ideas?

Did you put the backup on the root of the sdcard? I think it needs to be in the TWRP folder. You should first make a backup of your current rom even if it's stock rooted.

Someone explained to me TWRP won't recognize a backup with a serial number from a different phone. So essentially, I will just have to forego it. I used Wug Toolkit to fix this issue and just flashed everything to stock and had the same toolkit unlock and root. Using ADB was a fail and cost me a whole afternoon lol

[Q] Stuck Booting, should I factory reset?

I'm sorry if this sounds annoyingly silly, but if I do factory reset on my Nexus 5, will that delete all of my pictures, PDF document, videos, music, etc2?
I am aware that the app will be wiped clean like how the phone is first received, but I'm not sure if factory reset will also delete all of my stuffs I mentioned above as well.
The reason is, I tried flashing 4.4.4 to my android from android development page. Initially, I was a bit skeptical when "flash-all.bat" is not working because fastboot says there is no "system.img" in the zip file. So flashed the .img files one by one, and everything looks good.
However, when my phone tried booting up, it got stuck at booting animation for hours. I suspect this is because I have a lot of app in my phone and the fact that I'm going from 5.0 to 4.4.4. So I'm thinking of doing factory reset, but I just wanna make sure if I really need to copy all of my stuff first because doing this takes quite some time as well.

Yeah thanks for the answer over there.
I'm still curious about flashing 4.4.4 though.
IIRC, last year when I run the "flash-all.bat" script, it seems to work just fine, but now it doesn't. I wonder why?
