[One (M8) Q&A, Help & Troubleshooting] clax6:
Hi all I think this will help a lot of you as the HTC online guide is very vague.

When you first open Google drive via the app you are greeted by your additional 50 gig of free space .

And when you go into settings>storage> then right at the bottom it should display your Google drive storage but it doesn't!

You need to follow these steps.

First open your Google drive app and go through the setup to activate your free storage.

Then you need to use the mail app and create a new email.

The press the attachment button which is a paper clip.

Then scroll right to the bottom and select file.

Then it will ask you if you want to link your Google drive account to your Gmail account and which Gmail account you want to select.

Now go to phone settings>storage and right at the bottom you will now see your Google drive storage space!.

I rang HTC as I could not understand the poor online instructions and he told me to do a soft reset. And I said wait! Let me just try this and it worked and then he asked me step by step of what I did and he thanked me and has passed it round his colleagues at HTC!

Hope this helps someone!

Here is the HTC link http://www.htc.com/us/support/htc-one-m8/howto/465032.html

Now you have read my guide it sounds obvious what to do!
[One (M8) Q&A, Help & Troubleshooting] Electronic Punk:
Great tip, for those wondering you need to use the HTC Mail app, not Gmail.

I now see my Drive storage under storage settings!
[One (M8) Q&A, Help & Troubleshooting] UberSlackr:
Or you can simply clear the Cache/Data for the Drive app, and then log back in. Your updated storage limit will display.
[One (M8) Q&A, Help & Troubleshooting] Seapup:
Thank you for solving my problem!

Last Updated 2014-09-23
[Acer Iconia A700 and A510] Shreps:
Nice, if it's working fine, I hope you will also support the A510/A511 ;)
[Acer Iconia A700 and A510] Ziyan:
Of course, I'll see what can I do when I get everything (OC, UV, ...) working here :) waiting for a tester...
[Acer Iconia A700 and A510] Sterist:
it is indeed slow. even when completely debloated plus stripped of "essential" system components that I personally do not use. I will try this right away. will report back within an hour in this post.

[MENTION=2633638]Ziyan[/MENTION]

it boots, runs, everything seems standard. not seeing any performance increases though. same ol' 10 to 15 fps :( is there anything more you wish for me to test with it? I replaced this tab a while ago with galaxy note pro 12.2 so I can't really use it enough to check for random reboots
[Acer Iconia A700 and A510] Ziyan:
Thanks, that's good, it means I can continue improving it. I need to check the kernel periodically after a big bunch of commits, because if something gets broken, it can be hard to find what causes it if from a thousand things :) I'll push a new version and changelog later today or tomorrow.
[Acer Iconia A700 and A510] Sterist:
sounds good. quote this post when it's uploaded, it'll send me am email notification and I can get right on it.
[Acer Iconia A700 and A510] Ziyan:
Here's a new version. Before testing it, please make some benchmarks with the previous version (mainly 3D), because - if everything works as it should -, the GPU is now working at 520 mhz instead of 416. It should also have CPU overclocking and voltage control support, so please install Trickster Mod, or something like that from Play Store to see if it works (screenshots are welcome). If it works (i'd be a bit surprised lol it was too easy), please run some benchmarks again to see if there's a noticeable difference. I've got 12 pages of commits waiting to be merged, so yeah, if something got broken, I better fix it now :silly:
[Acer Iconia A700 and A510] Sterist:
just woke up and leaving for work in 20 minutes. when I get there and settle in (about an hour and 20min from this post) I'll test it

which benchmark though, antutu?
[Acer Iconia A700 and A510] Ziyan:
Yeah, antutu will do, just note the invidual points :)
[Acer Iconia A700 and A510] Sterist:
woah woah... I just went to download the second version and the tab was dead from 77% last night, still warm.

there's a wake problem, screen will turn on one time after booting up but only that one time

and a sleep problem, after manually turning the screen off it will not turn back on (and kills battery very quickly!)
[Acer Iconia A700 and A510] Ziyan:
Thanks for the report, I'll investigate the problem tomorrow (it's 01:30 AM here :silly:). If you could take a dmesg (while turning the screen off, then trying to turn it back on), or last_kmsg, that would be great help! If you don't know how, refer to section 2 and 3: http://xdaforums.com/showthread.php?t=1520508
[Acer Iconia A700 and A510] Sterist:
higher score / lower 3D performance is v1

lower score / higher 3D is v0

recent apps cleared and CPU set to 1400 performance and ROW

no app gives OC/UV options with v1

I don't have access to a pc at work so can't run dmesg properly for this, and I'm having trouble reproducing the sleep crash now :(

this is probably all exactly what you did not want me to say lol

edit: so, I got it to crash again (yay!) but can't get klast to work (read only fs) I tried mounting various directories as RW but honestly I have no idea which to do... and here's dmesg which may or may not contain what you need.

I know it might be a little early to ask but any chance you could implement Frandom? :D
[Acer Iconia A700 and A510] Ziyan:
Thanks for the detailed report, I think I revert Franco's hotplugging driver for now, seems like it's on a rampage. May try again in the future.

As for the last_kmsg, your first command was correct, it's just that it doesn't always get created.

We'll see about Frandom when we get things working nice :)

Here's a build with the stock hotplugging driver, report back if it still crashes.
[Acer Iconia A700 and A510] Sterist:
ok I let it idle for about 30 minutes (that was enough to crash every time I left it alone at work) and so good so far.

still no OC/UV though

edit... idle 2 more hours and no problems
[Acer Iconia A700 and A510] Ziyan:
Great, let's see if CPU OC/UV works with this one. If it does, don't forget to run a benchmark, as GPU OC didn't work till now :)
[Acer Iconia A700 and A510] Sterist:
still no CPU OC/UV. also, that 52mhz step has never worked on any ROM or kernel I've tried, that may extend battery life
[Acer Iconia A700 and A510] Ziyan:
Ok, it must work now.

About 52 mhz, it's so low that any small background work would ramp up the CPU to hispeed_freq, so in the end, it would shorten battery life. The same thing happens with Galaxy Nexus if we go down to 180 mhz, which is a lot, compared to 52 mhz ;)

I've added about 200 commits since your last try (this is a great daily activity :silly:), the kernel is getting to be on pair with a Nexus 7 kernel soon if we get OC/UV and some more extra things working :highfive:
[Acer Iconia A700 and A510] Sterist:
ok so UV menu now loads but doesn't look to work quite right - not usable. this is the menu I was looking for that did not load before :)

OC still does not work though

about 52 (51 actually) every time it is selected, after I leave the screen and come back 102 becomes the selected minimum automatically, even if lock frequency at 51 :(

need benchmark? and ty ty your time!
[Acer Iconia A700 and A510] Ziyan:
At least we're making progress :good: try this one, and also try trickster mod (specific and general menu).

Benchmarks are welcome, those 200 commits should improve performance a bit, though I think most of them can only be seen in real usage (low memory killer, zram, ...) :p
[Acer Iconia A700 and A510] Sterist:
bootloop, won't get past Acer logo

benchmark is from the last kernel
[Acer Iconia A700 and A510] HornetRider:
I don't now. I don't use ART, because I use many Exposed Framework modules.

Make a backup, flash the kernel and activate ART.

If it doesn't work, restore your backup. [emoji6]
[Acer Iconia A700 and A510] kraoc:
I used ART to try it because of improvements it should do... Not sure I can see any improvement in daily use.

I had some lag after installing Z2+ and had to reinstall my a510 completely after a full wipe and put CM11 M9 + Z2+ ...

I also reinstall Xposed to allow more indeep control of my tablet... Including Greenify :)
[Acer Iconia A700 and A510] Ziyan:
I've got the device again for some days... working on fixing the A700 kernel.

Anyone interested in OmniROM? It's my favorite ROM on my phone :)
[Acer Iconia A700 and A510] dadecamp:
I would like to try OmniROM.
[Acer Iconia A700 and A510] jasonzarko:
I would like OmniROM as well.
[Acer Iconia A700 and A510] chacal1906:
Oh yes ! I would like too ! I've omny on my phone and i love it !
[Acer Iconia A700 and A510] HornetRider:
I think, Omni would be great.

But the kernel is much more important [emoji6]
[Acer Iconia A700 and A510] cyberdroidXDA:
It depends about which model you're talking about? (A510/A700) :p
[Acer Iconia A700 and A510] Shreps:
We can compile Omni for both of them I think ;)
[Acer Iconia A700 and A510] Elibl:
We could give you access to our (@Shreps and my) picasso project https://github.com/picasso-m-mf-dev we have a separate branch for every ROM and I think the twrp branches should be already good to compile omni and you won't waste your free github repos ;)
[Acer Iconia A700 and A510] Shreps:
And your Kernel could also be added on this project too (when stable enough).

We can also plan to offer AOKP ROM for A700,

and why not add Omni and/or SlimRom branch on the repo too !

Being 2 dev with an A510, and 1 with the A700 device seems very great to tests every ROM and/or Kernel ;)
[Acer Iconia A700 and A510] Ziyan:
Thanks, sounds great :p

I've got omni running, had to change a few minor stuff to build it properly. I'm trying to contact the omni devs to get us official :good:

About the kernel, I'm on track with the error on the A700.
[Acer Iconia A700 and A510] coolhot_fdb:
OmniROM sounds interesting. I'd like to test on my A510.
[Acer Iconia A700 and A510] nchc:
You guys are awesome. My vote is for Slim, but beggars cannot be choosers.
[Acer Iconia A700 and A510] cyberdroidXDA:
Cool, let us know when it's ready ;) :thumbup:
[Acer Iconia A700 and A510] Ziyan:
About Omni, it's going official next week... I'll be your device maintainer ;)

About the kernel, I'll begin adding features like OC next week too, as I don't have the device now... btw, if anyone has a spare tablet (any of these do from the A510 to the A701, mint condition isn't necessary), I'm willing to pay the shipping to get it here...
[Acer Iconia A700 and A510] cyberdroidXDA:
Well, your next update sounds really interesting but I do not have a spare tablet here.

The only way is, you release the new kernel and we test it for you. With a previous nandroid backup, should be no problem. ;)
[Acer Iconia A700 and A510] kraoc:
Any news since september, 6th ?
[Acer Iconia A700 and A510] Ziyan:
I'll try to make something on the weekend... I'm busy with my exams :crying:
[Acer Iconia A700 and A510] kraoc:
If it's for exams... priority to exams !... What are you doing there !... Go study !!!

:)
[Acer Iconia A700 and A510] qweewq22:
We wait for you ;)
[Acer Iconia A700 and A510] chacal1906:
any news of this one?
[Acer Iconia A700 and A510] Ziyan:
I'll try to come up with something on the following week :) my semester is ending :victory:
[Acer Iconia A700 and A510] Mad07:
Could we have the possibility, that the Audio.r-submix.default.so will be available?
[Acer Iconia A700 and A510] Ziyan:
So far I've got OCing up to 1.5 ghz work like it should (so if you set 1.5 ghz, it will actually scale all four cores up to that freq). I'm tinkering a bit more with it, up to 1.7 ghz (that's the harder part, as I need to add some custom dvfs tables for the high freqs) would make me satisfied with the OC part of the kernel :rolleyes:
[Acer Iconia A700 and A510] coolhot_fdb:
Nice to hear that there is a progress. Sounds like a good message. I wish you all the best.
[Acer Iconia A700 and A510] chacal1906:
Good news !

1,7 would be good !

Thanks for all your work on our device !
[Acer Iconia A700 and A510] farris:
Any news for an update? :)
[Acer Iconia A700 and A510] Ziyan:
Sadly, my father sold his A700, so without testing, I can't really work anymore on this :( putting up the R2+ builds with OC to 1.5 ghz (I wasn't able to complete OC'ing, that's why it only goes to 1.5).
[Acer Iconia A700 and A510] kraoc:
Is it the same as previous or this is about your new work ?
[Acer Iconia A700 and A510] cyberdroidXDA:
Thank you very much for your great work so far.

I'm sorry to hear about the sold tablet. Is there any way we can help?

I will test the kernel tomorrow and let you know about the results.

Btw: R1 was succesfully oc'ed to 1.6Ghz so, would it be possible to copy that to the R2 kernel for both devices?
[Acer Iconia A700 and A510] cyberdroidXDA:
I have tested the new kernel (A510) and I have good and bad news for you:

The good news:

My tab is starting up and under heavy circumstances I was able to see the clock speed at 1.5 GHz.

The bad news:

The process "com.android.phone" is constantly dying. So, it can't be used for now.

I will try to reset my tab later (wipe all partitions) and flash everything again. I hope that will help.

Will keep you updated.
[Acer Iconia A700 and A510] cyberdroidXDA:
Wiping all partitions didn't change anything. I'm sorry to say that.

The process (see previous post) is still crashing constantly.

Any idea is very welcome.

Tablet has been recovered to previous state.
[Acer Iconia A700 and A510] etag:
For me too, A700.
[Acer Iconia A700 and A510] cyberdroidXDA:
I found the problem. It seems this kernel is working with the Omni ROM only.

I have flashed the newest Omni version and it's working fine.

My tab was running CM11 stable during the first test and it seems the kernel is not compatible with that.

Special thanks to HornetRider for the hint.

(A510)
[Acer Iconia A700 and A510] kraoc:
Hello :)

Is there a chance to see this Kernel upgraded to Lollipop 5.1 ?
[Acer Iconia A700 and A510] Elibl:
We may generally update to it but ziyan has no tab anymore so development has stopped here
[Acer Iconia A700 and A510] kraoc:
That's a shame!

Thanks for your response.
[Acer Iconia A700 and A510] Ziyan:
Let's have one more try, I'm starting to run out of ideas lol

That benchmark is pretty good, though I don't know how it performs with the stock kernel, I see +1000 points over the images you posted a while ago :)
[Acer Iconia A700 and A510] Sterist:
boots, OC works! trickster can't seem to make performance governor setting stick so I'm going to let the device cool down a minute and run bench again.

haven't tried UV yet

edit: while trickster couldn't make CPU settings stay, performance menu in settings and Voltage Control app did, BUT cpu would not actually go to 1500. also, UV has same problem, null tables?

edit 2: benchmark added with performance on 1500 / displaying 1400

edit 3: my fault with trickster, didn't see the check at top to apply lol did that and 1500 still "unused" though :(
[Acer Iconia A700 and A510] Ziyan:
Finally, I managed to borrow the A700 for a day :laugh: fixed 1500 mhz, and I think I also managed to diagnose the UV problem. It works for some frequencies with Trickster Mod (it shows 1 mhz for the 102 mhz step, and so on), Acer refactored and modified the frequency table in the JB update, so I need to adjust the UV commits from the N7 to them. Will try to do that tomorrow.
[Acer Iconia A700 and A510] Sterist:
glad to hear that! I've been very disappointed with how slow this quad core device operates

I may continue using it for miscellaneous things if this turns out good, as I'm sure it will :)

my new tab finally got a working TWRP today so it's time to root it
[Acer Iconia A700 and A510] Sterist:
[MENTION=2633638]Ziyan[/MENTION]

could you upload it please? :)
[Acer Iconia A700 and A510] Ziyan:
Yeah, I'll upload the last build when I'll be home (~2 hours from now). Currently, UV works wonderfully with SetCPU, and here are my findings about OC:

By default, the max CPU frequency is 1.4 ghz. However, that's only the "turbo maximum", or whatever nvidia calls their solution: one core may go 100 mhz higher than others - but only if only one core is used, so basically, it's useless (just watch the time spent at 1400 with the stock kernel - below 1%...). So basically, we're 100 mhz behind the maximum frequency because this feature. After finding out that this causes issues when OCing, I disabled this feature. So for now, I accomplished 102-1700 mhz frequency ranges (I removed 51 mhz, as it's useless). By default, maximum frequency is set to 1700 mhz, so - because the "turbo mode" - the maximum frequency is actually 1600 mhz (but it won't boost to 1700). I tried to set voltages close to stock, so this frequency should be pretty safe (we also have thermal protection, so it won't overheat). Now, antutu scores ~16500, which is nice. There's only one problem: the maximum cpu frequency can't really be changed. If it's changed with an app, it becomes buggy and sets about 1150 mhz as max freq (and I also had a freeze when I messed with it). I'll try to fix it somehow, but for now, I consider it as a minor bug only.
[Acer Iconia A700 and A510] Ziyan:
Here's it. Should be pretty stable if you don't touch min/max frequencies :p

I'll soon start working on support for UV-ing some more things and user-configurable GPU OC.
[Acer Iconia A700 and A510] Sterist:
that is... very strange

when I bought this tab, on the back of the box it says it has a 5th cpu core for battery saving. did you see anything in the kernel related to a 5th core? curious
[Acer Iconia A700 and A510] Ziyan:
Yeah, we have that running @ 620 mhz instead 500. More info can be found here: http://www.nvidia.com/object/tegra-3-processor.html. Unfortunately, I didn't find a way to see whether it's active or not, as it's handled on such a low level that monitoring apps can't see it. Will try to look at the N7 forums about that (if there's a way to see it, the hardcore devs over there surely found it lol).

Btw, that page says: "Up to 1.7 GHz single core /1.6 GHz quad-core". Maybe I should tinker a bit more with that turbo mode so we can enable it to reach 1.7 ghz single core?
[Acer Iconia A700 and A510] Ziyan:
Try this new build, take a look at trickster mod. Custom GPU OC, LP Core voltages, GPU voltages, RAM voltages :fingers-crossed: still need to fix MPU voltages tho, it's the CPU, but for some reason trickster mod reads the frequencies incorrect :confused: but setcpu works fine...

Also, I had to add back 51 mhz, removing it can cause some bugs.
[Acer Iconia A700 and A510] Sterist:
maybe it's for screen-off only and / or handled by proprietary parts of the stock ROM
[Acer Iconia A700 and A510] Ziyan:
Updated OP with the latest release. The main differences from yesterday's build are tons of bcmdhd commits. It should be stable, but I don't have the A700 with me to test it further, so report any issues :good:

I'll have a pretty hard midterm exam next week, so the development will slow down a bit, as I need to study :crying:

Also found out that the N7 guys have problems with the MPU voltages table too, here's an explanation: http://xdaforums.com/showpost.php?p=41804567&postcount=2029. So the only "real" bug now is the CPU min/max frequency :victory:
[Acer Iconia A700 and A510] Honusnap:
Nice, following the thread... :)
[Acer Iconia A700 and A510] peter_altherr:
ziyan, your kernel makes me thinking i have a whole new a700. it is much more responsive as before.

thanks a lot for your work.

greetings

peter
[Acer Iconia A700 and A510] dadecamp:
I wanted to let you know that I am on the Pac Man Rom but can't get this to boot. Freezes up. Will have to try cm11 .
[Acer Iconia A700 and A510] dadecamp:
Ok, so I went back to cm11 but after flashing kernel it booted all the way but got a "google system error" message and it froze. I rebooted but would freeze on cm logo.

What am I doing wrong?
[Acer Iconia A700 and A510] Ziyan:
Did you do a factory reset after switching to CM11? If not, please make a backup (so you can get back your things if it won't work), do and then flash CM11 again with this kernel only. If it doesn't work, I'll make a special build for you test :highfive:
[Acer Iconia A700 and A510] dadecamp:
Yes, I did but will do it again to make sure.

---------- Post added at 08:43 AM ---------- Previous post was at 08:34 AM ----------

I wiped everything then flashed Rom and kernel in sequence. Booted fine but keyboard kept fc. Rebooted and all seem good. Need to go back in and flash gapps.

---------- Post added at 08:51 AM ---------- Previous post was at 08:43 AM ----------

Flashed gapps but froze again during "Android is upgrading"

Will have to come back to this later.
[Acer Iconia A700 and A510] Ziyan:
Thanks for the reports, I'll make you a special build tomorrow without OC to see if that's the issue :highfive:

Anyways, I had the opportunity today to play a bit with the device. I think I found out why setting min/max frequencies become buggy. It works from 102 to 1150 mhz, for anything higher, it goes back to 1150. I'll fix it in r2, which is already in the works (hint: I almost immediately update my github if I do something), so OC will be disabled by default.
[Acer Iconia A700 and A510] dadecamp:
I wiped everything then flashed Rom and kernel in sequence again. This time I was able too boot but again keyboard fc. Wiped again and finally got in. Flashed minimum gapps and so far so good.
[Acer Iconia A700 and A510] dadecamp:
No luck for me.I've had several random reboots. Going back to Pac Man. Thanks for your efforts. I will follow your progress.
[Acer Iconia A700 and A510] Sterist:
sounds like you're using ART and/or crossbreeder
[Acer Iconia A700 and A510] dadecamp:
No art or crossbreed
[Acer Iconia A700 and A510] chacal1906:
Thanks for your kernel !

I love it !

thanks for your work.
[Acer Iconia A700 and A510] Elibl:
really great stuff here amazing to read. [MENTION=2633638]Ziyan[/MENTION] keep on the track your work is highly appreciated ;)

I'll may build an a510 version and try...

Gesendet von meinem Galaxy Nexus mit Tapatalk
[Acer Iconia A700 and A510] Ziyan:
Could someone please post the A510/A700's boot partition size? Just in case I decide to add something, lol...

Anyways, I'm still working on fixing max frequencies over the 10th step (1150 mhz)... something got messed up there :mad:

[MENTION=2633638]Ziyan[/MENTION]: fyi you deleted picasso_m_defconfig (A510) in your last commit it's totally the same configuration as the same hardware only resolution differs

i tried it on a510 and it worked the first time but then after doing an update of ParanoidAndroid and flashing the kernel again it always froze directly after boot process will get a dmesg the next time

so what are your plans are you even considering to go up to 3.4 :p if it's even possible^^

so here is an a510 version with ParanoidAndroid ramdisk
