For the benefit of others on stock (unrooted) ROM.
You can wipe htc One cache partition to improve battery life, especially after ROM upgrade.
My One had a lot of wakelocks after KK upgrade from Google Play services.The method below resolves this issue.
To do this, first ensure Fast Boot is un-checked under Settings > Power.
Next, power off the phone
Access the Bootloader menu by holding down the Volume Down button, and pressing Power. Your phone should boot up.
When you see a white screen with three cartoon Androids, release the buttons.
You should see a menu (white background)
Use Volume to highlight "RECOVERY" and tap Power to select.
Your phone will reboot and display a black screen with a red exclamation mark in a red triangle.
Press Volume Up and Power. Release once buttons are flashing couple of times.
You should see another menu. (dark background)
Highlight and select "Wipe cache partition" (before tapping Power to select, be sure that "Wipe data/factory reset" is NOT highlighted, as this will result in loss of data).
When the process is complete, highlight and select "Reboot system" to boot the phone into the OS
.
YMMV. HTH
I like that this works, but I wish someone would explain WHY it works. What's present in the cache that causes the problem?
@SundayDebate
Wiping the cache can indeed solve some problems but if this improved your battery life its only a coincidence. Probably wiping only Google Play's cache would have done the same thing. Anyway the cache is rebuilt after each updates or ROM flash (clean installed) so there is no need to wipe it again to "improve" your battery life. If you don't have any problem then there is no need to wipe the cache, this will not magically improve your battery, in this case it only did because it fixed that wake-lock issue. Nice guide btw, but i personally disagree with the "wipe your cache so you'll get better battery life" approach but that's a nice "how to wipe the cache partition using stock recovery" guide :good:

I am having real problem with this build. I tried posting this question at the correct thread, but admins of forum wont let me. So I have to post it here. Below is the actual build that I am using. NAND version is what I use.
"[6.Nov.2011][MAG/cLK] NexusHD2-Gingerbread V3.2a (GWK74)(Android 2.3.7)[tytung_r13]" update
Everything else is working except the wifi connection. Cant get it to connect to any network. At first I thought it was due to the security type, so I got another wireless router,and make it OPEN without any security, still the wifi would not work.
Any idea will be really be appreciated since this is my regular phone.
Thanks for your input.
hmm, try clearing the cache and the dalvik cache, then fix permissions (all in CWM) and reboot.
Maybe it helps.

Am afraid, I don't know how to do that. Let me try to look at the xda website, but if you have ready made info please post for me.
thank you.
Well, first of all get into the Clockworkmod recovery.
It depends whether you have CLK or MAGLDR, check this just by trying.
If MAGLDR, turn off your phone and press and hold your "end call" button till a menu appears, now use the volume buttons to select the 8th option "8. AD Recovery" and confirm by pressing the "start call" (leftmost) button. now you should be in CWM.
If CLK, and in android. press and hold the "end call" button as if you were to shutdown the phone, but dont select "shutdown", press "reboot", then select "recovery" and tap "OK" to confirm. now it should reboot into CWM.
If you don't get those options in the shutdown menu just turn off the phone and press and hold both "end call" and "home" (the one with the little house) buttons, now it should start CWM.
Now in CWM use the volume buttons to navigate to the " - wipe cache partition" option and confirm with the "call" button. then navigate to " - advanced", press "call", and select "Wipe Dalvik Cache" and answer yes if it asks you if you're sure about it. then, still in the advanced menu select "Fix Permissions"
If all succeeded, reboot your phone by pressing the "return/back" button to get to the main menu of CWM and select and " - reboot system now". Or just pull the battery and reinsert. BTW the reboot should take a little longer since the phone needs to rebuild the dalvik cache.
Hope i've been clear enough.
Oh and still it's not guaranteed that this'll fix your WiFi problem, but it will give you some insight into CWM.
Hi, a friend has one of these and I'm trying to help him root/custom rom. I used the Droid X Boot strap from market after the root. I can get to CWR from the bootstarp but how do I get there from power off mode? (for example In HTC Thunderbolt it's power and volume down)
Also, can/should I use rom manager after boot strap?
I'm using Liquid's latest but very buggy, SD card won't get recognized. Any suggestions on the most stable rom (preferably AOSP)
Check my sig for an extensive Droid X Specific How-to.
Getting into CWM from power-off isn't available on 1st init roms...
But some roms have a "fail-safe" that you can turn on booting into CWM after every boot up.
On a couple (MIUI, EncounterICS) roms, a new Boot-menu has been made where you simply press the down-volume button right when this blue light flashes during boot.
(You obviously need to be on one of those roms for it to work)
I'd suggest CM7 or MIUI so far for stability as far as (true) AOSP goes.
EncounterICS is coming along nicely, however...and shows promise in the near future.
Links to a couple of roms that I'd suggest are also in the post linked in my sig.

Thank you. I actually ended up with the Liquid for her. It seems like all the problems was comong from the bad SD card which gave out and she lost everything. I'm trying to see if I can somehow get some of it back but that's another story...
I'm a big fan of CM7 but don't like to install nightlys for others, especially if they live in another state. I don't see a stable CM7 so I will wait. It appears that Liquid is also AOSP and is playing nice MIUI is nice but I'm kind of sick of it. I love vanilla Android. All these theming isn't for me.

awesome, I guess this is what I was looking for: to get to some kind of recovery when stuck. Hope I don't have to visit this post though.
Does anyone else's Turbo take a relatively long time to clear the cache in recovery? I've done it a few times now and each time it has taken close to 10 minutes. Other phones I've tried usually finish the clear in a minute or so? Is anyone else seeing the same thing?
Mine always takes several minutes. I've never actually timed it, but I would guess 5 or 6 minutes?
Mine takes about 20min every time.
IMO I think that a DT thing across the board, at least with the XT1254. I have 7 other friends with the DT and they all experience the same thing( and so do I )
It is a painfully slow process on the DT.
My maxx even in cm recovery takes 10 minutes to clear
Me too I think it's related to the recovery both are unfinished versions of recovery
How is anyone clearing the cache? Going by the steps online, I can't even get to a point to clear the cache. When it says click up to select, it just goes up to the option above. Hitting power just boots the phone. Can i have TWRP yet? - XT1254

When you boot into recovery press and hold the volume up button and tap the power button once to activate the recovery command list
same here on maxx 7/ 10 min
Same here. Not really an issue tho
What it takes to clear the cache and the cell is in operation ... the difference is that everything is done from the recovery while the other cell .. makes the second stage when turn on the phone ... still need to wait a while.
sorry for English
has anyone tried to clear cache after using the mofo root tool? I tried to get into the recovery so I could clear cache, but am unable to do so...When I select recovery I just get the green android icon with the red icon on top. Any advice?

see post #9 in this thread,
Hold the volume up button and tap the power button once when you are in recovery
Yes it takes long to erase cache. I do it one a week.

I'm having the same issue. I follow the instructions to get to recovery to a "T" and still get the little "dead" Andy with the red exclamation warning triangle.
This is, of course, after rooting with mofo root.
EDIT: This is what worked for me - power off phone > hold volume down and power until fastboot loads > use volume up/down to scroll to Recovery > press power to select > once dead andy screen appears, hold volume up and tap (do not hold) power > recovery should load.
I have a strange issue with System Uupdate and am not sure if it's causeing my phone to be buggy.
If I check my System Updates Tab I get Last System Update: "Software not updated to G935VVRU2APB5" Failed - Mar 29 2016....error code 454
If I then go and check for new system update, I get "Your Samsung ....is up to date. No update is necessary at this time."
If I then check System update history I see "Software updated to G935VVRS2APB4 Mar 19, 2016..."
However when i check about phone my Baseband version is G935VVRU2APB5.
Anyone know what do I do to get this cleared up?
Thanks!
Since there's not really a way that I've seen to wipe cache without root, (you do have ADB but even with we don't have access to those partitions) (to the best of my knowledge) so unfortunately a factory reset is more than likely your only option.
This happened to me also. Glad I'm not the only one.

You can wipe the cache by powering off the phone and then holding down the Volume Up, Home, and Power button until the phone vibrates. Let go of the power button but continue to hold the others. Use the volume buttons to scroll down to "Wipe Cache Partition" and press the Power button.
Hope this helps.

Thanks for the tip. I hate to have to do all this without root. Have a good day!
I accidentally enabled Emergency Mode, and now my phone is stuck on the boot screen. It is a G935f, and I have used Package Disabler Pro. Is there any way to restore my phone?
Hard reset your phone or flash the stock rom
Power off your device.
Wait for a few seconds while your phone is shutting down.
Press and hold the Power, Volume Up and Home buttons simultaneously to get into Recovery mode, Mine takes about 20 seconds or so before anything happens.
Use Volume keys to navigate and Power button to select an option in Recovery mode.
Once in, from the main menu, using Power key, select wipe data factory reset.
If you want to clear app data cache too, choose wipe cache partition. Clearing cache often fixes various software related issues.
When done, go back to main recovery menu.
Select reboot system now and that’s about it.
