[Q] Stuck on JB 4.2.2.... OTA useless - Nexus 4 Q&A, Help & Troubleshooting

I'm serious, after trying to unbrick this device I can't go through an OTA otherwise it will bootloop during the dalvik/art optimizations on first boot. First it bricked during the 5.1 ota and then I tried to get into bootloader after it apparently bricked showing the red led error. Cache and data couldn't mount and I've tried formatting and fastboot erasing but no dice. I tried adb shell with the cmd e2fsck /dev/block/platform/msm_sdcc.1/by-name/userdata but nothing was prompting for a repair so I did something stupid and ran mke2fs /dev/block/platform/msm_sdcc.1/by-name/userdata and all seemed well but now the device can't boot a rom anymore especially after writing the stock images into the device. So I tried to downgrade and eventually used 4.2.2 and it somehow booted completely into the stock rom.... How the heck do I start all over?

/sdcard unable to mount?

I tried encrypting my phone today while on CM10.1 and it rebooted and hung on the google screen for a few minutes so I held the power button and it rebooted and went back into CM10.1 except it said, encryption was unsuccessful and i needed to do a factory reset. So I let it reset, but it kept sending me to that page. So i booted into recovery tried to manually wipe it and it said /sdcard could not be mounted. I am currently using a linux toolkit and trying to push the google sock image, so far it has pushed the bootloader, boot, and recovery. I am sitting at system and thinking my phone is borked.
Someone else mentioned that they can't mount /sdcard .... are you actually trying to mount it?
Are you using fastboot to flash the appropriate stock files?
From bootloader: fastboot flash boot boot.img
fastboot flash system system.img etc... ?
Or running the flashall.sh script in the stock downloaded files?

[Q] [HELP] N7 Soft-brick without solution

Hello everybody!
Last week installing cyainfire my device felt in bootloop..
I tryed all the ways possible but i' m sure someone of you will be better
I have destroyed everything on the nexus, also the recovery.. The only one working is the bootloader (obviously unlocked)
What i can do at this moment is: flashing a custom recovery TWRP on the device by toolkit and from there activating the ADB sideload. Trought cmd the working and useful commands are:
Code:
adb push rom.zip
adb sideload rom.zip
From the recovery i wasn' t able to flash the pushed zip...
I tryed several times with the sideload but the nexus was telling me that it couldn' t mount /system and /cache... So, it wasn' t working..
But finally i tryed wiping everything whit the commands:
Code:
fastboot erase system
fastboot erase cache
fastboot erase userdata
And formatting data by the TWRP..
(It is still saying me it cannot mount the /cache)
The ADB sideload of the device was working but anyway it fails flashing the sent zip..
What could be the problem? I have no more ideas...
Thanks a lot
p.s. english is not my first language
P.S.2: Solved on my own.. this time the sideload command worked.. sometimes i thing the linux kernel has its owns intelligence..

I think I am bricked

So at one point, I accidentally deleted the OS off of my phone, but I still had TWRP installed. The only solution was to flash a rom through ADB, but TWRP didn't have ADB for whatever reason for me, so I flashed CWM which did have ADB. I was able to flash CWM after I pushed a rom through ADB and install Android 4.3 w/ root from nexus4root.com. It worked correctly, but I noticed that I only had 5.66gb of storage on my phone. I have the 16gb variant which would have about 12gb usable. So I followed a guide here in xda to get back my 16gb. I was told to wipe my phone step by step and flash a factory image. But ere are my errors not
- When I try to flash the factory image, it says 'missing boot.sig, system.sig, and something else.sig'
- I have no recovery on my phone
- When I try using fastboot commands, it says FAILED (command write failed (unknown error))
I am pretty stuck here. And I did redownload the root files.
EDIT: I was able to fix fastboot and flashed TWRP, but my devices is encrypted and requires a password
You should be able to clean your encrypted user storage by using "fastboot erase userdata", and you can do it for /data /system and /cache partition as well.
Or go into TWRP, if it ask for password, just press cancel. Then go to Wipe -> Advance -> Select "Format Data" and it will do a full wipe and cleaning out the encrypted partition.
As for using fastboot to restore to stock, shouldn't be any problem as long as you have the correct drivers and latest ADT package from Google.
I did something similar and had encryption on. My fix was "fastboot flash" the stock system, boot and recovery (4.3 for me). After getting back in my phone and verifying everything was there I re-flash CWM and re-rooted.

[Q] Nexus 4 OTA update failure

Kit-Kat OTA came out for my Nexus 4 today and I went to apply it but during the install it errored out and the phone subsequently enters a boot loop. I can get into a recovery shell and attempt to push the update via sideload but I get an error:
Symlinks and permissions...
set_metadata_recursive: some changes failed
E:Error in /tmp/update.zip
(Status 7)
Installation aborted
I'm 99% sure there's a binary in /system/xbin/ or /system/bin/ thats set immutable (chattr +i) causing this to fail but I can't launch an adb shell from recovery to fix this. Can anybody help me out here?

Are you using stock recovery to do this?
You pretty much explained why, but if you had rooted the phone it could fail due to other reasons too.
If you have an unlocked bootloader then you can boot TWRP (not install, but boot by fastboot boot twrp.img), it have its own terminal and you can go in and chattr -i that file.
Or with unlocked bootloader you just "fastboot format system" and flash the full system.img from the factory image. Or use TWRP to flash a stock rom.
I don't see how else you could have ran a chattr command to the /system without root. But without an unlocked bootloader you pretty much only have the choice of factory reset or unlock the bootloader in which both will wipe all data. But I'm pretty sure beside fastboot erase and format, not even factory reset in recovery could get rid of an immutable file. There is no adb access in stock recovery beside adb sideload signed packages (otherwise every android phones will be very unsecure).

Unfortunately, you're correct. I was rooted at one point and had an old 'su' binary around that was immutable, completely forgotten about. My bootloader is stock atm and I'm still stuck on 'no command' I'm accepting the inevitability that I'll have to wipe and start over but I'm not even sure how to flash the factory firmware now since I'm either stuck in a 'Google' boot loop or I get 'no command'.
Any suggestions?

When you see no command that is normal. To bring up the stock recovery menu, while holding Power first, press Volume Up.
Google bootloop have nothing to do with flashing factory image since it required using fastboot in fastboot mode (not in recovery), aka the bootloader menu. Links in my signature have instructions to flash factory image.

Hello,
this is my situation:
- switchin-on my new moto e4 (XT1762)
- boot into recovery (TWRP)
- in TWRP, I am able to 'work', i.e. install LineageOS 15.1 (this is my main goal)
--- I WIPE
--- I INSTALL the lineage ZIP file (lineage 15.1 20180310 unofficial woods
--- I REBOOT
BUT, sadly, the reboot is done again into TWRP.
The installation of lineageos did not report any error.
How can I check, that what I've installed so far (TWRP and magisk) is correct and working?
Did I forget something? E.g. do I have to install GAPPS as well? Or Magisk? Or SUperSU?
Shall I try another custom ROM? Or another version of lineageOS? (Oh, yes, I tried Lineageos 15.0, but I got 'ZIP error'.
Thanks for your help!

I imagine you are having the same problem that I was having. This is what I think happened, there is a particular partition which TWRP fails to erase, if this is the case I believe you are able to boot into the device by hitting start in the bootloader, hold volume down and power then select start. Tell me how it goes

Thanks for this hint, frederick.
Unfortunately, it did not work.
I rebooted to bootloader mode, then I pushed 'DOWN' and 'POWER' for several seconds - but I could not select anything - display was switched off and the device rebooted to TWRP again.
That's strange, because yesterday I've got this 'MENUE', when pushing 'DOWN'&'POWER' for selecting FACTORY, RECOVERY, ... but this does not appear now.
More facts (it might help):
- After switching on the the device, I get this 'Orange state' message.
Perhaps any other hints?

I have no other recommendations as to what to do. Just flash stock firmware with rsdlite and everything will be back to normal, if you have any data that you need to back up you can use TWRP to transfer the files to a PC

In twrp select reboot bootloader. In bootloader, tap volume until you see "start". Tap power. Do not try holding buttons together in bootloader. It doesn't do anything. Single taps.

After "REBBOT BOOTLOADER" in TWRP, I get a black screen, where (on the very bottom) there are two lines: => FASTBOOT mode
=> device unlocked
Tapping or holding the volume&power buttons does not work in this state.
As mentioned before, by any reason I do not have this nice menue anymore, the one with RECOVERY, START, ...
So this could be the problem, right? Is my bootloader not working properly? Which part is telling the device to startup either in TWRP (=recovery) or into the Bootloader/System?
Mmmmh....

Fastboot mode is bootloader. Why the options aren't there I couldn't tell you. I see you flashed a rom for woods. Do you have the mediatek version? Hopefully you didn't flash wood stuff on a Perry device. Bootloader may be different. I have Qualcomm. Was that option ever there in fastboot mode?
This is how to fix the recovery loop. And possibly boot you in to whatever is left of your os.

Thanks again for your hints!
First of all, my device variant is XT1762, i.e. woods. I did not use PERRY software.
The bootloader options (RECOVERY MODE, FACTORY MODE, etc.) were there, but it seems I've somehow broken this peace of code... I believe this is the reason of my problems. Unfortunately I do not understand the Android boot sequence...
However, I tried >> fastboot erase misc << via terminal:
result:
erasing 'misc'...
FAILED (remote: partition table doesn't exist)
finished. total time 0.009s
I double checked it vie file manager in TWRP: there is no MISC folder.
It seems, my only option is to go back to stock ROM... :crying:

I think the partitions are different in mtk version. But I would try flashing stock.
I have exactly the same problem after trying to flash lineage 14.1 to my XT1762.
Unfortunately I have only a TWRP Backup of my stock system before the flash and recovering that didn't fix the problem.

I know what a pain in the ass my Perry variant was just to get the root going, so I can just imagine your frustration.
Did you guys take the update they're pushing out on the phones? Check. Some of the updates might be forced or you may accidentally said Okay and didn't realize it- that could be the reason why you're having trouble. The significant other got an update on the E4, and now can't do root.

Hello!
In the meantime I actually deleted everything and flashed the Stock ROM on my XT1762.
After that, my Bootloader menue (RECOVERY MODE, FACTORY MODE, START, ...) appeared again...
I felt lucky and started the whole procedure again: use TWRP, backup, delete Cache, Flash custom ROM, delete Cache, restart... and finally, I got lineageOS 15.1 and CrDroid running on my phone.
Now I use CrDroid, because LineageOS 15.1 did not Support my SIM Card... ? However, I am happy with CrDroid: fast, slim, nice looking, ...
So in the end, it seems that I deleted a specific part in my Flash which caused the "boot Loop". But I could repair it by flashing the Stock ROM again.
Thanks guys, you're doing a good Job!

Thank you for the hint on rsdlite, didn't know the program! Unfortunately I have two problems, have only access to an old XP box (I'm normally on a mac), and rsdlite doesn't recognise the phone, driver problem presumably... And the program doesn't recognise the format of the backup I made with TWRP...
Is it possible to repair the file system on the phone via terminal? Or to delete parts of the system safely and reinstall the stock system? The other guy apparently did something like that. Or to unpack a custom rom and place the parts via terminal so it can install on next boot?
Thank you!
Did following check:
mount /data
mount: '/dev/block/mmcblk0p27'->'/data': Invalid argument
e2fsck -n /dev/block/mmcblk0p27
e2fsck 1.42.9 (28-Dec-2013)
ext2fs_open2: Bad magic number in super-block
e2fsck: Superblock invalid, trying backup blocks...
e2fsck: Bad magic number in super-block while trying to open /dev/block/mmcblk0p27
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
Would it be safe to rmdir /data and mkdir /data ?
Thanks...

Rsdlite is not meant to install your twrp backup. It's for installing the official firmware package. And you need to install moto drivers of course.
