Google Nexus 5 :: Fastboot Wipe Cache Partition Very Slow On 6.0?
Oct 20, 2015
it takes about 5 - 10 minutes to perform a wipe from Recovery, where in Lollipop and before, it was a few seconds. A couple of websites have corroborated this.what's changed in 6.0 that a cache wipe takes so long? I'm on an unrooted N5 and performed a clean factory flash (and re-locked the bootloader).
Code:
mkfs -t ext4 /dev/[device]
to
Code:
rm -rf /cache/*
Or something, I mean, even formatting a heavily encrypted partition shouldn't take that long (especially one as small as /cache).
Nexus 5 taken a while to wipe cache partition? It takes a good minute or 2 on the nexus 5 but on the nexus 4 it takes 2 seconds. Both are running Android 4.4.2 the nexus 5 and the nexus 4.
I now for the past hour am trying to wipe the partition cache but when I get to the last step where it shows the no command instead of it bringing me to the recovery menu it just reboots every time.
To wipe the cache partition, follow these steps:
Turn off the device. Press and hold the Volume Up and the Volume Down and Power keys at the same time for about 10 seconds. An image of an Android lying on its back will appear. Press the Volume Down key twice until "Recovery mode" appears on the screen. Press the Power key to restart in "Recovery mode." An image of an Android with a red triangle will appear. While holding down the Power key, tap the Volume Up key. The Android System Recovery screen will appear. Release all keys. (But it does not appear it just reboots the device and brings me back to the lock screen every time) Use the Volume keys to scroll to wipe data cache partition and press the Power key to select. The phone will restart.
Just a question for everyone that occasionally wipes the cache partition from recovery like I do. I'm on my 2nd replacement and after I set it all up I wiped the cache partition but for some reason it takes longer than usual for the process to finish. Usually it would be like 2 seconds where now it takes around 35-40 seconds to complete. How long does it usually take you to clear your cache?
1. Power off phone. 2. Press Volume Down & Power. 3. Click Reboot to Bootloader. 4. Click Boot to Recovery Mode.
After extensive researching and contacting HTC directly, I found out that I am supposed to get a few options where one of them is 'Wipe Cache Partition'. However, all I get is a black screen for a few secods, then an icon of my phone with an exclamation mark on it. That appears for about a minute, after that the phone reboots.
Any reason that's not working? I'm running Lollipop 5.1 and Sense 7.0.
I've got a Sprint Galaxy S5, and just did the OTA update to Lollipop. Initially I was getting a notification about a Google Play Services error, and all the icons for apps stored on my SD card were grayed out, but still usable. The Google Play Services error and the icon issue seemed to take care of themselves with a re-start, and everything seems to be working OK now.
I've read here and other places that doing a Wipe Partition Cache after the update often smooths things up and can improve speed, with no risk of losing data. Well, I've tried about a dozen times to do the 3 button press, but all I ever accomplish is restarting the phone. Is there a trick to getting into Recovery, or should I just keep trying?
I've been making it a point to, once a week, go into 'system recovery' and wipe the cache. It isn't to correct an issue that not wiping can create, but rather as maintenance to keep the phone running well. I was curious how often the rest of you wipe the cache?
The first time it took about 10 mins. 2nd time failed after 30 mins and I had to restart. 3rd time just took 25 mins but completed. What's going on!?!?!
So, originally the problem was the phone's screen was going black straight after the Google logo, I had a hunch that it was a fault with just the screen as it was pretty badly smashed and seemed the phone was running in the background and you could get the backlight to come on. Then all of a sudden it would stop doing it and then start again intermittently.
I flashed to 6.0 to see if might be some random ROM error, but still exact same problems. Screen came back and then went again. So I grabbed a new screen and swapped out the part. Now at least I don't have a smashed screen and faulty digitizer.
Now the problem appears to be slightly worse. The phone gets to the Google logo again now but now it completely shuts down after it, but it still gets to fastboot! (Is fastboot stored on another chip than FW? If so that worries me.)
Since Windows 10 is rolling out today I would like to know if adb and fastboot drivers are up to date for it ? Can I install them with universal naked drivers?
I tried to update my Nexus 5 to Marshmallow using ADB/Fastboot and Googles images. I have followed a number of different (yet the same) approaches to flash the unit and NOTHING works. I tried to go back to 5.1.1 and can not restore the unit. It has not bricked (yet) and not sure what to try next. I have read options that call for reformatting parts of the operating systems but fearful this will brick the unit. I have flashed the bootloader, phone, recovery, userdata, sys, etc., and nothing works. I know others have had trouble with Nexus 5 based on what I have read however to date not be able to restore the device.
Recently, I was trying to replace old battery in my Nexus and something went wrong. The battery wasn't replaced but the phone didn't boot up. When unplugged, the phone didn't react at all (and I know that battery % was enough). When I plugged it in, the battery indicator showed up, disappeared after a second and it was happening in a constant loop (this appearing and disappearing). I tried to boot up the phone but only Google showed up and phone turned off and the battery indicator was again reappearing.
I managed to access fastboot but couldn't do anything more (when trying to enter recovery - same thing as with booting up). Flashed stock 6.0.1 and nothing changed. The phone was sent to LG but they said the warranty won't cover that and offered to replace motherboard for price around $230 which for me is a bit too high as for this quite old phone. They've sent me also this photo (URL...). Now I'm waiting for them to return the phone and maybe I'll try with another LG service.
Maybe symptoms are suggesting something and it can be easily fixed. Right now I can't do anything because the phone isn't back yet but when it's back before giving it to another service?
My N5 has a hardware fault where the phone thinks the power button is permanently pressed, so as soon as you try and boot it, it turns off again.
I am able to get to fastboot, by holding down the volume down button and power. But from there, I cannot boot to recovery or normal system boot.
I have been unable to fix this, and I really want to get some of my app data off. Is there a way of extracting a backup somehow from fastboot? I'm guessing no, as you can't access via adb through fastboot?
I am trying to flash 4.4.3 to my N5, but fashboot flash command is stuck at "sending.." and the fastboot screen is stuck at "downloading..." If I hold the power button to reboot the phone then it boots fine.
I am running a stock image on my N5 with root and need to add an apk into the system partition but the problem is that I have only 4mb left on there and the apk does not fit. Is it possible to resize the partitions and:
Still keep your data and/or Allow for OTA installations down the road?
I need to install an apk to /system/app but my system partition has no free space. Using "df" command in terminal emulator, it says 0.0K free in /system. I have Android 6 DP3 and I've never pushed any file to /system before. Is there any way to extend system partition?
After rooting device (not my first time, but my first time with my nexus 6 which was a virgin) I tried installing a custom font. I downloaded it and tried installing "X" font and said my system storage was full. I tried clearing some stuff but failed. I thought it was an error so i downloaded a new app and failed too.
I verified if my phone was rooted and it is. Later I decided that I wasn't in need of a custom font so I left it at peace, but I remembered about Xposed framework and want it to install it just for the modules , but failed terribly after showing me a message that said "not enough storage space." Broke my heart. I unrooted and OEM locked my phone and re-rooted to no avail. Still the same ol' problem.
When in the root process, I remember while booting into custom recovery temporarily I saw this new message (I had never seen before) that said Something about the system partition to set it to read only for future OTA's processes and I left it untouched.
Also I checked on Titanium back up and other apps. Cache: 256mb-------------- 13.4mb used, 242mb free---Good System: 2GB ---------------------2GB used, about 300KB free---Bad Data (userdata) 26.5Gb----2.5GB used, 24.1GB free---Good Ram---- who cares. Its ok.
I want to have space to install Xposed, all these fonts and stuff. How can I free space or somehow to let my phone now there's more space or idk something.
Like the title says I can't write anything new into my rooted N5's system where it says system is out of space or something like that... I can copy files of KB sizes but not MBs... I have V4A libs and SuperSU in the system and now been trying to put in avast antitheft which is not working... This also happened when I tried to install xposed... BTW mine is stock lmy48i rooted with elemental x... Now I had to delete Google books just to install the antitheft!
OK so my phone was basically wrecked with the original Lollipop update. Did the cache partition wipe, factory restore, and for a while it was ok.. then it started acting up again - getting super hot, quick battery drain, apps crashing. Applied the other update from Verizon and went through all the same steps again, with the same results. Each time I reinstalled fewer and fewer apps. Now I've just done another cache partition wipe, factory restore, set up no email accounts, installed no apps, and am running in safe mode.. and my phone feels pretty hot. What's the best/safest way to check the health (temp) of the battery? Should I install GSam for a while? Or is there a way within the stock battery stuff to check the temp?
I flashed Android 6.0 to my Nexus5 and rooted it with NRT. I can't copy a new hosts file to /system/etc because there is to less space. df shows in fact just 4k of free space.
Is there any way to increase the usable internal memory by reducing the size of the system partition (if you use a very lightweight ROM and GApps) and add it to the emulated storage?
I have a Moto Maxx XT1225 but I believe clearing the cache partition is the same as the DROID Turbo (it's immediately below my question).
I always get hung up after step 5 (below) - i.e., when I press the up volume 10-15 seconds and then tap the power button, NOTHING happens...no additional menu options appear as listed below for step 6.
FYI, here's steps 1-6 as mentioned above:
1. With the phone powered off,*press*the*VOL*DOWN KEY*for 2-3 seconds then*POWER*key then release;
2. The device will display*different BOOT*OPTIONS;
3. Use the*VOL DOWN*Key to SCROLL to Recovery*and*POWER*Key to select;
Tip: If the device reboots, you may have*waited to long to make a selection, you*will need to begin the process again.*
4. The device will display*the*Motorola logo and then*the*Android in distress*(logo with Exclamation mark);
5. Press and hold the*VOL UP*key for*10-15 seconds.*While still holding*the*VOL UP*key*tap and release the*POWER*key;
Tip: You can*try this step, holding the phone in landscape. If you are*stuck on step 6, try a*force reboot by pressing the Power key and Vol Down key, and start the process again.
6. The device will display additional menu options (Text will appear in*BLUE);
My colleague was trying to unlock bootloader "fastboot oem unlock" and after that it stuck on erasing userdata for around 2 hours. Then he restart device now while flashing it says "cannot mount /cache"and few other errors.
I tried flashing Stock 5.0/5.1 nothing works (Stuck at loading screen). Then i tried Android 4.4.4 and it worded.
Now at this point in recovery mode it still says "cannot mount /cache" and few other errors. I cannot use gallery/camera/playstore. When i open gallery it says "No external Storage available".
I cant get past step 4 using "official" motorola directions to clear the cache partition after upgrading to 5.0.
"1. With the phone powered off, press the VOL DOWN KEY for 2-3 seconds then POWER key then release.
2. The device will display different BOOT OPTIONS
3. Use the VOL DOWN Key to SCROLL to Recovery and VOL UP Key to select
Tip: If the device reboots, you may have waited to long to make a selection, you will need to begin the process again.
4. The device will display the Motorola logo and then the Android in distress ( logo with Exclamation mark)
5. Press and hold the VOL UP key for 10-15 seconds. While still holding the VOL UP key tap and release the POWER key
Tip: You can try this step, holding the phone in landscape. If you are stuck on step 6, try a force reboot by pressing the Power key and Vol Down key, and start the process again.
6. The device will display additional menu options (Text will appear in BLUE)
7. Use the VOL DOWN Key to scroll to wipe cache partition and the POWER Key to select this option
8. The device will then perform the partition wipe
9. The device will reboot and start the normal power up sequence
