Hello everyone!
I tried to restore the stock image using Nexus 4 Tool Kit (both the original one and the Wug's one), and everytime I tried, the script stucked at "writing system".
I manually flashed system and userdata images with Wug's tool kit and everything went well but I only have 5Gb memory instead of 16.
Does anyone know why?

[HOW-TO] Fix internal storage if 16GB now shows 8GB
Sent from my Nexus 4
OP...
In future, don't use a toolkit. Do it yourself
I'm having a similar problem to the OP - I'm trying to do a factory restore, and am unable to flash the "system" image. I can't boot, recovery mode won't work anymore (I get a red warning sign instead)...
I think all of this has to do with me being naieve and following a youtube video instead of the CM wiki to install CM 10.1.
How can I unbrick my phone?

When going into recovery the warning sign is the splash screen for stock recovery. This likely means that you have not yet flashed a custom recovery yet, which is necessary to flash CM. First read this guide to unlock the bootloader (if you havent already), then flash a custom recovery (preferably TWRP). After you have installed the recovery, download CM as well as the latest gapps package and place them somewhere on your internal sd. Boot into recovery and go to the wipe menu, then swipe to factory reset. Finally flash the rom and gapps, and then reboot.

if you are doing a factory restore and DONT need to flash everything individually than don't. yes its good to know how to do it manually but if your flashing everything back just use the script that google provides.
reboot to bootloader/fastboot and run the flash-all.bat file and its all done for you. no toolkits no playing with commands that you dont know properly etc.
if you dont know how to do it right pick the least complicated option.

I am using the .bat file... I've also tried the toolkit, and both appear to use the same basic procedure, and they stop at "writing system" no matter what.
Does anyone happen to know how the .bat file and toolkit get access to the phone? ...because I can't see it in adb (I'm guessing it's because I can't boot the phone.) However I can get into fastboot and recovery modes on the device.
I cannot get the device (nexus 4) to boot or connect in ADB mode to my computer. What can I do??
UPDATE - PROBLEM FIXED
I un-bricked my phone
SOLUTION this is what worked for me, your mileage may vary
Install ADB drivers, etc. from Android SDK (google how to do this)
Flash custom recovery (can be done easily with Nexus 4 Toolkit here on XDA) - I used TWRP Touch Recovery.
Once that is done, shut the phone off completely and boot into Fastboot (hold volume down and power)
Use volume keys to select Recovery Mode, then hit Power
In recovery mode:
Wipe > Advanced Wipe > Check off the box beside "System" > Swipe to Wipe
Go back to recovery mode main screen:
Wipe > Format Data > Follow the instructions on the screen
I think this step is what did it. When having problems with partitions, just format everything and start over
Now we should be able to write to the System partition, meaning you can flash a ROM and get your phone to boot again.
Follow the rest of these instructions to quickly flash the stock Android image from Google onto your phone.
Go back to recovery mode main screen, once again:
Reboot > Bootloader > Follow any additional instructions it gives you
Download Google Nexus 4 factory stock image "occam" (Google it)
When that is downloaded, open it with 7zip. Inside there are some files, one of which is called image-occam-jdq39.zip. Inside are some images - unzip those as well. You'll need the system.img file in a bit...
Using Wug's Nexus Root Toolkit (Google it - install it on your Windows PC):
Open the program
Launch advanced utilities
Hit the System button to permanently flash to System partition. Hit "ok" on the window that pops up.
Find the system.img file I mentioned back on step 10 and select that, when prompted, and open it.
If all went well, your device will now boot into the stock Android ROM.

Stuck, but working
I was flashing the 4.3 image using the included flash-all.bat (but I edited it to remove -w parameter so that it wouldn't wipe my data).
In the 'writing system' step, the command window got stuck. In the phone screen, at the bottom, it said 'writing' for a while and then that also went away. I waited for ~40 min, and still the command window was at 'writing system', so I closed the command window, and booted my phone by selecting start from the bootloader.
And voila! It worked. Booted in under a minute, the flash was a success, I got JB 4.3 without losing any of my data.
Lost my root and custom recovery though. But I knew that would happen. Gonna try SuperSu for 4.3 now, after flashing TWRP.
Had the same problem, tried everything! With my tiny powers, but it kept stucking at "writing system" . I thought that I bricked the device, so for the last hope, I installed WugFresh's Nexus Toolkit and did a Fast Stock + unroot. It Installed everything flawlessly! I'm gonna donate to that guy! He's a godsend savior.
Info about phone:
Nexus 4
Rooted
Previous rom: carbon rom 4.3 last nightly
TWRP 2.6.3 installed
So was trying to install the latest carbon rom 4.4 nightly and kept getting this error: "set metadata recursive: some changes failed
error executing updater binary in zip"
Then the flash would fail. Thing is I foolishly formatted, as its been months since id flashed a rom, and now have no OS on the phone so am stuck in a bootloop. I cant get the phone to connect via usb and appear on windows 7 my computer. I have tried mounting in usb otg, but it says its unable to.
What can I do to fix this? Thanks.

just flash lastest twrp or multirom one and will work
reboot device into bootloader mode then just download and extract universal naked driver(when installing check make desktop icon,for easy find), download and install minimal adb and fastboot, download lastest twrp our multirom one, or lastest cwm, go to device manager,search for anything with Neuxs or google or adb on the name, double click it, and then select the 2nd option(to search for driver), navigate and select the folder where you extracted universal naked driver and install. it will throw an warning, just click install anyway.
after install, open minimal adb and fastboot, it will open a cmd window, after that, copy the .img you downloaded(twrp,multirom twrp,cwm, they all give .img downloads), rename to recovery(if you have extensions enabled dont delete the .img in the name) and copy to your local disk c:. after that, get back to cmd promp(the one that minimal opened) and type
"fastboot erase recovery"(press enter)
"fastboot flash recovery c:\recovery.img"(press enter)
then after it finishes press the volume button(up or down, dosent matter)untill the text on the screen changes to Recovery Mode,when it do,press power button and wait till recovery shows up. then you can do the wipes and install the rom
Hello,
I saw that the OTA update to Lollipop was available on my phone today, so I went ahead and let it download. Upon completion of the download, it restarted and applied patches, then restarted again and has been stuck in boot loop for about an hour. After reading several other threads on how to try to reset the phone, I'm stuck. When I try power + volume up or down, the LED status indicator flashes red and I never get to any kind of other screen. Am I completely screwed? I previously had stock 4.4.2 with no modifications.
Finally was able to get to the bootloader menu. Apparently having the phone plugged into the charger was preventing me from getting there for some reason. I ended up having to wipe the phone to get it to boot
so you can get into clock recovery right? download nexus 4 toolkit..that might save your phone. I suggest you to unroot and flash everything to stock and then unlock again and start everything from scratch. good luck.
Similar issue on an OTA upgrade to an unrooted N4. It's stuck on the Lollipol boot screen with the rotating Circle thingies.
I can get to the Android System Recovery but there's no CWM or TWRP on my N4. I'm guessing a factory reset will fix it but is there a way to preserve my pics/files on the phone before doing so?

I guess TWRP Recovery has option to enable MTP and you can access the internal SD card by connecting mobile with computer using usb cable.

Flash TWRP Recovery using fastboot.
1. If you have otg y cable, connect it and use file manager to copy all the files.
2. OTG method is failed then select “Mount”, then select only “Data” and connect your Nexus 4 to your computer and Enable MTP in TWRP. now you can use adb pull and push commands.
I ended up going the factory reset route, which wasn't really a bad thing. My photos had been backed up in dropbox and the play store remembered all the apps and were able to reload them. The only things I really had to do was reload some music onto the phone and re-enter passwords for apps.
Same story here: sideloaded the OTA zip file, then had bootloop. Tried a few approaches, but none worked. In the end only wiping the data was the solution for me. Lost some userdata in a few important Apps...
I went through this yesterday. The only way to get it to boot is a Factory Reset from Recovery. It works like magic, but sucks you lose the data.
Got the OTA yesterday and also got a bootloop(stuck in boot screen animation). I couldnt afford losing my photos/videos as i had no backup , so i figured out a super easy to get it to boot without wiping data .
I was unrooted with stock recovery running stock 4.4.2, bootloader was unlocked. I flashed CWM recovery through fastboot and wiped chache+ Dalvik from there then simply rebooted the phone .
I had already tried wiping cache from the stock Android recovery,needless to say that didnt work for me.
If anyone else is having the same problem please try the method above and report back, cheers!
I post this on Google Product Forum 2 days ago. Hope it helps

(updated 29/11/2014)[not perfect but it is a SOLUTION]
The idea of this is to downgrade your nexus 4 without wiping your data, which means stuff you will need includes:
1. adb and fastboot on your computer (I am using mac but you can find it on windows as well. There are tones of website and forums telling you the latest method of getting it onto your computer)
2. factory image of nexus 4(I use 4.4.4, since that's what it was. I don't have the time and energy to try to do the same thing with lollipop. you can try can leave a comment).
update: do NOT try to flash 5.0 rom using this method. You will be stuck at boot loop again
3. usb cable
4. nexus 4 with unlocked bootloader(the process of unlocking bootloader will wipe your device)
5. computer
steps
1. unzip the factory image (something.tgz)
2. for me, after unzipping the .tgz, I still find another .zip inside. unzip that too.
3. hold vol+, vol-, and power button simultaneously to enter fastboot mode
4. open terminal(mac)(it would probably be cmd for windows)
5. connect your nexus 4(in fastboot)
6. to make sure it connect successfully, type "fastboot devices". if something like "005040c0d54bb291 fastboot" appears, you are good. Otherwise, try reconnect your device/boot to fastboot again/use another usb cable
7.now we need to tell the terminal to navigate to the location of the unzipped factory image. to do that, i suggest you put the unzipped folder to somewhere easy to find, like desktop. these are some commands to help you navigate:
"ls" allows you to look at whats inside the current directory of the terminal. For example, this is the output after typing "ls" for me:
some folder Photos
nexus4image.tgz how many folders do you have
5.zip occam-ktu84p
more folder occam-ktu84p.zip
after knowing where you are, use "cd" (below) to go to your folder
"cd" means change directory. For example. "cd Photos" will brings me to the "Photos" folder. And then if I type ls, I will see a whole bunch of photos in my photos. If you go to the wrong folder, type "cd ..", and it will bring you back to the previous folder.
8. flash bootloader.
enter the following command, BUT REMEMBER TO CHANGE THE NAME TO FIT YOURS(DIFFERENT VERSIONS HAVE SLIGHTLY DIFFERENT FILE NAME AT THE END(type ls first to help you type the correct name)
fastboot flash bootloader bootloader-mako-makoz30d.img
9. reboot bootloader. just copy and paste
fastboot reboot-bootloader
10. flash radio
enter the following command, BUT REMEMBER TO CHANGE THE NAME TO FIT YOURS(DIFFERENT VERSIONS HAVE SLIGHTLY DIFFERENT FILE NAME AT THE END(type ls first to help you type the correct name)
fastboot flash radio radio-mako-m9615a-cefwmazm-2.0.1701.03.img
11. reboot bootloader. just copy and paste
fastboot reboot-bootloader
12. flash system
system.img is located inside the zip, use ls to help you navigate. This steps takes the longest time, total time on this step is 87 seconds while the others are less then 1 second
fastboot flash system system.img
13. flash boot
boot.img is located inside the zip, use ls to help you navigate.
fastboot flash boot boot.img
14. flash recovery
fastboot.img is located inside the zip, use ls to help you navigate.
fastboot flash recovery recovery.img
15. format cache(not the memory, so everything should be fine)
fastboot format cache
16. reboot and wait
this will reboot your device. You probably have to wait for a while to initialise all the apps. after than you are good to go!
fastboot reboot

Hello. Sorry for my english. I want flash my phone via rootjoy to Arcatarc's MIUmIZERO and i only can see miui logo. next i want back to stock rom from needrom via sp flash tool, i followed instructions and i stop, when red status back not change for 20 minutes. and i can't charge my phone, can't conected to pc, can't turn on, looks like dead. How unbrick my phone? please help
problem solved
how did you solve it? please let me know as i am in the same boat
If it's stuck on the MIUI screen then it's possible the bootloader wasn't flashed properly.
If you can reboot the phone in fastboot you can flash the bootloader via PC.
it is dead . the phone wont turn on . the pc wont recognise it anymore , it was fine ... untill i tried to flash stock through sp flash tool .
i was running antarcts emui,.... tried flashing using the method on umi digi forum : http://umidigi.com/forums/topic/how-to-restore-rom-version-3-03-2/ ... preloader was unticked, and when i tried firmware uopgrade option...nothing happened, and the phone was dead after that.

I managed to make it boot.
The problem is I have twrp and some chinese recovery . And I cant go back to stock.
Fastboot cant flash recovery for some reason ... so I can go back to rootjoy.
use adb side load an try to flash a working rom, the original one from umi website or emui.
can you get in recovery mode? volume (+ or - try both) and power button for some seconds
if yes go adb side load, (check google) and transfer an original rom, then flash it again in the recovery
My Umi Zero is bricked, because I cannot mount /system. I can get into the TWRP, but I cannot do anything, even restore my backup because of this. Does anyone have idea what to do?

If the system is unstable with popups etc or with damaged partitions you can get past that with TWRP.
Boot into recovery Wipe/Advanced Wipe. Then after that is completed, without rebooting, Format Data. That should sort out your partitions.
Then Install ROM from the recovery. It will need to be on the device. If your new ROM is not already there plug in a USB lead and transfer the zip file from your pc.
If you want to re-install your backup, do that instead.
If that doesn't work Backup in TWRP, even though there is no system. Then copy your Nandroid backup (must have been made via TWRP) and paste into the same folder as the Backup you just made, overwriting if asked.
I have had to do all this myself!
Good luck
Hi all!
I have the simular problem.
Umi Zero can not start.
But recovery seems to be working.
1) TWRP recovery 2.8.2
After full wipe, my TWRP recovery write "Unable to mount /SYSTEM"
The same message I have if I try to flash original 3.10 ROM via TWRP.
It is impossible to mount or format or repair SYSTEM via recovery
But it is possible to see files in FileManager and go to Fastboot and ADB mode
2) ADB and Fastboot mode.
Impossible to flash any partition.
"boot" - checksum error
"recovery" - "not support flash" message
"system" - filesystem created, start "erasing" and freeze. If I disconnect phone, have got message "failed (too many links)"
adb sideload does not work also
3) SP Flash Tool
I tried with full 3.10 ROM and with CRT 3.0 recovery
Download mode and Format+Download mode.
The same result: yellow bar finished and got message "Checksum error" or something like that.
All this experiments change nothing in phone. I still have TWRP recovery and "unable to mount /SYSTEM" message.
Any advices?
I am not English-speaking guy, as you guess), sorry.
It looks like memory become write-protected...

Hi
Did you Advance Wipe and Format Data?
I found that worked.
Alternatively, you could use Rootjoy to put just about any ROM on. CM 12.1 works ok.
Once you have a stable installation, install a custom recovery like TWRP 2.8.7 from Needrom. I used Mobileuncle, an app from the Playstore. However, I looked just now and it doesn't seem to be available.
I have tried Rashr, but couldn't get it to work.
Once you have it all stable you can flash the ROM you really want via TWRP.
Good luck
Advance Wipe and Format Data or flashing new stable ROM via TWRP did not work for me. The same result- unable to mount /system.
Rootjoy and Mobileuncle could be used if phone is working. My phone works in recovery mode only.
I tried to flash different recoveries but did not find the way to do this. As I wrote, Sp Flash Tool, Fastboot and Adb Sideload did not make any changes to my recovery. I think, flash new recovery will help if I found the way)
Or if I discover the method to test and\or repair /system partition from PC
But thank you for answer)
@YrP
Rootjoy works from your pc
Yes, Rootjoy- works)
But for establish connection phone must work too.
And not in recovery mode.
@YrP
I have already done all this with my daughter's Zero.
However, it's in bits at the moment while we wait for a part from China. So I can't go through the process with you live, step by step.
I am in the UK.
If you send the phone to me I will try and fix it for you.
PM me if you want to go ahead and I will let you have my address.
I am in Ukraine, it is too far from UK)
I will keep trying to find the way to fix it by myself.
But thank you very much for your attention and advices.
@YrP
I have got my daughter's phone back together and fixed (mostly).

My UMI is still bricked(
It is flash memory problem, I think.
I am trying to find the tool to remap internal memory, to move SYSTEM part to other physical place. But did not find it yet.
What was your way?
Zero stutters, processes crash or the phone will not boot into System
Have you already tried a Factory Reset or re-installed the ROM?
What can you do?
You could try the following. However, if your phone blows up, orders a takeaway or elopes with your girl-friend, please don’t blame me.
1. Provided you already have TWRP custom recovery installed and your phone is powered down boot into Recovery: hold the volume down and power buttons until the Zero logo appears then let go
2. Select Wipe/Advanced and select Dalvik Cache, System, Cache and Data. Slide to execute
3. Select Format Data/ type yes and slide to execute
4. Reboot into Recovery without installing a new ROM
5. Select Backup, choose SD card rather than internal storage and give the file a memorable title like Blank Backup and date. Select Boot, Logo, Recovery and Uboot. Slide to execute
6. The next step requires you to have a Nandroid backup made via TWRP already made of a stable ROM. If it isn’t stable or you don’t have one I have attached a clean backup below. It’s derived from Cyanogen Mod 12.1. This is based on Lollipop 5.1, with Gapps and rooted. I have found this to work. As the title of the file suggests, it’s a factory reset, ie no personal data included. Download it to your pc unzip and save it.
7. Connect your phone to your pc via USB cable and open Windows Explorer
8. Find your stable backup or the one below and drill down until you see the folder with 15 files, starting with data.info and ending with uboot.emmc.win. Select all and Copy.
9. Open another window and find the TWRP folder on the SC card of your phone. Drill down to the same folder containing similar files as to step 8 above. Click in folder and Paste. When prompted select Copy and Replace, all and Ok
10. If your pc doesn’t show your phone and the SD card, in recovery select Mount and USB storage.
11. In Recovery select Restore and the Blank Backup (or whatever file name you gave it, now populated with usable ‘data’). Slide to execute
12. Give it time to load and boot up
13. You should be good to go!
If you don’t like CM 12.1 installing a new Launcher from the Playstore, like Cheetah will make it run smoother. Everything after that is down to you.
Of course, you could flash another ROM via TWRP
The backup below was made via TWRP 2.8.6. This is also attached below. You can install this via a previous version of TWRP as an image. Unzip it first.

I tried to update my phone to the latest version. I hit install from the notification, my phone reboots goes into TWRP recovery.... does nothing, then I have to "reboot into system" and then the phone boots up like normal.
Without updating to 6.0.1. Does anyone know why this is happening, or how to fix it?
I think you can't update the phone with official update method (Settings/About/System Updates) when you have unlocked bootloader and root.

You must return to complete stock, including recovery, before attempting an OTA update
Sent from my Nexus 6P using Tapatalk
As mentioned above, you can't use the traditional method of updating if you are are rooted and have TWRP installed. You will need to flash the images manually with your PC in order to update. There are multiple ways of doing this, but the easiest way I've found takes about 5 or 10 minutes and is documented elsewhere on this site, but long story short:
-install and confirm that ADB/Fastboot works on your PC and can see your phone
-download the latest image directly from google
-unzip the downloaded file on your PC and then unzip the file that was just extracted into your ADB folder
-edit the "flash-all.bat" batch file to remove the "-w" toward the end (to prevent wiping your data)
-put all extracted files into your ADB / Fastboot directory.
-connect your phone to your PC, power it on or reboot it into bootloader mode, and run the batch file that you edited (this will put you back to stock / unrooted)
-re-flash the twrp recovery image using fastboot
-re-root (install SU.zip using twrp).
That's my preferred method, and once you have everything setup (ADB / Fastboot working & factory image downloaded) is should only take a couple of minutes to perform.
As mentioned before, this is well documented elsewhere on this site. I may have missed steps or left out information as I am writing fast because I am currently at work.
Good Luck!
