[Q] Insufficient space on device. Can't install any app

Hi fellow blackers,
My optimus black was on Nova Rom 2.2 v8:
http://forum.xda-developers.com/showthread.php?t=1161015
And I flashed it to v20n:
http://forum.xda-developers.com/showthread.php?t=1441901
I followed the instructions specifically these two before proceeding with the zip install.
1. Wipe Data/Cache (if not wiped, might cause problem)
2. Advanced > Wipe Dalvik Cache (same as data/cache, might cause problem)
After flashing, I can't seem to install any app from Market. It says that I have insufficient space on device.
So did some searching (google and here on XDA):
Here are their suggestions:
1. Install Marketfix - unfortunately, I can't install this because it is already saying I have insufficient space.
2. Clear market cache - after clearing (cache and data), I still says insufficient space
3. Uninstall market update - Going to settings - Application - manage application then selecting Market, I don't see any uninstall button. Just Force close, cancel and clear cache, clear data..
4. Finally I saw knzo's supposedly fix for this: Something to do with file system (nova is on EXT4 while stock is on EXT3)
http://forum.xda-developers.com/showthread.php?t=1212370&highlight=insufficient
I wasn't able to try option 1 because the file was removed on all file sharing sites.
Options 2 and 3 - restore factory settings isn't working. The phone is not doing anything after I click Erase everything. It just hangs
Any other suggestions?

Try reflash ROM with wipe all data and cache in CWM including dalvik cash and formating partitions in "mounts&storage".
Or this!

Try wipe cache and dalvik cache...worked for me

hmm pardon me, but how do I boot into recovery? I tried powering the device on while holding volume down (also tried up and G button) but it didnt reboot into recovery.

Since I can;t install anything (rom manager etc.), I think I needed to do what you advised.
I was able to flash the stock then started up from there

How to go from OOS 5.0 to Stock Nouga

How to go from OOS 5.0 to Stock Nouga

Since you've made the spelling error twice, its Nougat, not "Nouga.".
I think the best way you could do it is flash the special Open Beta build on the Open Beta thread and then flash the stable build zip.
Whichever way you do the reversion, you will lose partial data, as N and O do not support each others app installations.

If you are unlocked bootloader, flash twrp 3.1.1-2 and clear dalvik data cache and system, and just flash them through twrp
dont use twrp 3.2.0-0 because you cant install magisk, it shows installed but magisk doesnt seem to be recognized in apps
I've just done that, and everything seems working flawlessly
Pls do hit thanks if i help you

Does your solution avoid erasing internal storage? Because that's the part that's preventing me as it can take too long getting my backups into the phone again.

i never format my internal sdcard partition
it's taking too long time to backup and restore it again
as i said, only format dalvik cache data and system thru twrp and you're good to go

download special edition nougat revert zip file and flash it via recovery
http://oneplusroms.s3.amazonaws.com...337224&Signature=BEA4IHd/rVFqoPd2gh7EvwaoSeg=
notes :
The build will wipe app and cache data, but Internal Storage will be saved (ie: pictures and files)
Users who revert their device back to the special build can still OTA update the device to Android O build at a later date.
Steps to revert:
Download special build
Copy to Internal storage
Reboot to recovery Mode to install
Choose “Install from Local”
Choose the downloaded build to install

Thank you so much for the answer Sir AviNash. I've got a question, if I swipe to factory reset, all my downloaded apps would be gone? Or their settings only? I am hesitating to downgrade because I am thinking that it would lost all my downloaded apps including the data. Am I correct sir?

Yes .. factory reset will remove all app setting and app data. You will need to backup appdata on cloud.
Storage data on SD card will not be touched. To be safe .. backup data on Internal Storage as well.

Now my phone is on v331, and this 331 version is bad,.. worse than the 327, but instead of downgrade to 327, I prefer to wait for your "334 upgrade file for 'UBL-TWRP&Root' user" like you did with the 331

Thanks for this

sir,can you give a tutorial to edit firmware updates for flashing on twrp?

Latest update 339 is proven to be stable and reliable release. Probably it's your phone hardware issue.
Maybe you can try to clear the cache first. If that does not work then try reset the phone. If still doesn't work then bring it to service center.

How to fix "No OS Installed" error

If you had problems (like myself) with installing custom roms via twrp where the system would stuck in a bootloop and the recovery would return "No OS Installed" error, here's the solution to how to fix it:
1. Enter TWRP
2. Go to Wipe - Format Data
3. Restart recovery
4. Copy the rom to internal storage and install custom rom
Enjoy!

Whoops, forgot it doesn't have the sd card slot I've edited the first post.
Apparently, when you change rom type (for example, from official stable to xiaomi.eu weekly), you have to do this complete device wipe. For updating to a new version only wiping dalvik and cache should do.

not work on me

Thanks but didn't work for me either. After following your instructions, the phone booted into TWRP again. It no longer says there's no OS, but it won't boot. Just stalls into boot animation for a while and then goes into twrp recovery... Bummer!

[GUIDE] GSI for US V40

Greetings everyone, i go by the name Ainz Ooal Gown. Here i bring you the a guide to flash GSI roms to your V40
Fist things first if you try this and end up with a brick or your device transforms and tries to take over the world; it's not my fault you messed up not me. So just read all of this thread not just the O.P to, and get out of a bind if you reply with "the thread is too long i wont read it please help" don't expect anything short of "there's a search bar use it"
Requirements
Unlocked bootloader
TWRP
Installation guide:
You need to download Lineage OS 16 by Xsavi i recommend the build "lineage-16.0-20190914-UNOFFICIAL-judypn(More LG Stuff use this).zip". Put into your external SD
You need to download a GSI from here https://forum.xda-developers.com/project-treble/trebleenabled-device-development i personally recommend Havoc OS 2.9 and Resurrection Remix 7.0 download the Arm 64 A/B Variant and what ever recommended Gapps Package is linked.
Extract the GSI you downloaded and copy the extracted Folder into your external SD.
Boot into TWRP and check your active Slot in the reboot menu.
Flash LOS 16 Install -> select the ROM zip -> tick Inject TWRP -> Swipe for install (if you're on a, it will be installed to b, and vice versa).
Go to and select Reboot Menu -> select your inactive slot -> select recovery and you should reboot into your inactive slot.
Go to and select Wipe Menu -> Swipe to factory reset
Select install and navigate to your downloaded GSI -> select install image -> select the GSI image -> select the bubble next to "System Image" -> Swipe to Custom Flash.
Select the wipe menu -> select advanced wipe -> select the square next to "System" -> select "Repair or Change File System" -> select Resize File System -> Swipe to Resize.
Install any Gapps and/or Magisk and reboot.
You will probably have to add your Carriers APN settings for Data and MMS to work.
Thanks to: @SGCMarkus @Xsavi

When I flash LOS16 into my inactive B slot, I am unable to boot into TWRP on slot B because there's some Lineage recovery in place and no option to flash anything and the sideload option doesn't work; I am checking inject TWRP. Am I missing something?

On step 9, I get a failed error on resize. The error is:
Code:
/sbin/e2fsck -fp /dev/block/bootdevice/by-name/
system_b process ended with ERROR: 1
Unable to repair system
Anyone know how to fix this?
EDIT: I tried to install gapps after this, but it failed because of insufficient space. Went to check the /system partition size, and it only has 65MB free out of 1637MB. Is there a way to restore the original partition size and start from scratch?

You have 2 things to try, 1st. resize again and see if the error happens again... 2nd. Reboot recovery and try once more I've had this happen to me.

I already booted into the rom. Would that affect anything? I'm gonna try anyway.

You can always factory reset after flashing gapps to get all your stuff synced and what not...or just add your account after and it may tell you to finish setting up.

Hey guys any workaround to get pie ? For at&t unlocked v40, currently in malaysia , dont have at&t carriers here .

So this would work with havoc 3 probably? I look forward to trying in a little.

If you mean Los 17 from SGC Markus? Then nope his rom has its own instructions and if you mean as a base for GSI well you can try but I haven't had any luck.

Is there a way to remove the GSI without reflashing the whole thing? RR is having an issue with the camera that is still in development. Is there any way to revert to the LOS 16 without losing my data?
