Wiping ?

I'm no expert, but I have been upgrading CM roms on my N1 for 3 years, and I have never needed, or heard it recommended, to wipe everything for an upgrade of the same rom, e.g. CM10.1v5 to CM10.1v6.

I upgraded to v6 of vj's great CM10.1, and have had no issues (doing just a cache and davlik cache wipe). By no means do I suggest I know more than vj - not even close - but I just don't understand the need for a full system wipe. Is this just super-cautious or is there a real reason to wipe?
[Nexus One Android Development] F i L:
Hey, I did not mean that the this ROM is not good. Actually this ROM is the best one for N1. It runs even smoother than 2.3.7. I just wanted to understand why no one can fix this issue. I suppose it is due to closed source drivers.

Anyway, personally I have given hope that this will ever be fixed. However, Vijendrahs has really excelled in this ROM. No random reboots, no freezes, everything works flawlessly :D
[Nexus One Android Development] thrik:
I'm sure the dev just wants to err on the side of caution. I wouldn't want to deal with potential issues raised by not fully wiping if I were a dev.
[Nexus One Android Development] anmino:
But for me, I encountered soft reboots and sometimes having some bearable lag..
[Nexus One Android Development] arnab:
any new update vijendra ???
[Nexus One Android Development] vijendrahs:
I will give one soon :)
[Nexus One Android Development] arnab:
Thanks
[Nexus One Android Development] rabies876:
That's odd. You're updating CM before slim bean?
[Nexus One Android Development] Vasya4:
For the ones experiencing soft reboots: please look for the apps that try aggressively to stay in memory, like ExDialer, etc. I've noticed that removing or disabling these apps (or telling them not to stay in memory, if possible) solves the problem. I'm not sure if this is universal solution, but it works for me.
[Nexus One Android Development] vijendrahs:
:)

Yes slim need to update to 4.2.2
[Nexus One Android Development] anmino:
Please update slim.. thanks
[Nexus One Android Development] viditbhargava:
Yes, please update the slim to 4.2.2, desperately waiting for it.

[MENTION=4493424]vijendrahs[/MENTION] is there a way to take your Wifi fix from your HTC Desire Rom and put it into my Nexus One Rom before you do a complete release? Is it just a simple copy and paste with a Root Explorer?
[Nexus One Android Development] HKYate:
Thank you, this ROM is utterly amazing!

I just can't send you money as Paypal doesn't accept donations to India from the UK at the moment. Does XDA or yourself have any other user contribution method?

Hi,

Did anyone else experience problems with wifi tether? as soon as I enabled the hotspot the 3G/2G connection is lost and I only got phone signal.

How to fix random/soft reboot with this Rom?
[Nexus One Android Development] clustered:
Yeah,always do having issue with random soft reboot... :(
[Nexus One Android Development] rabies876:
Soft reboot that's odd!

Just wait for the next update or try slim bean it's stable, very stable ROM and for that reason I've downgraded

the only issue i had was not able to install Google+ but it has been solved.

I had some soft reboots early on. Recently I figured out that my sd card had gotten screwed up somehow and it was causing a lot of problems, mainly with installations but some reboots too. I think it is from overclocking but I have no way to confirm or support that.

hello and thx to the dev for the nice rom !

can someone let me know how to get perfectly work A2SD on this rom ?

I try Y N Y, Y Y Y but it seems its not working perfectly... (not enough space when installing an app)

has someone a clear and efficient way to make it work perfectly ?

Thanks

[Nexus One Android Development] arnab:
vijendra waiting for ur update bhai..have to format the phone anyway so keeping tight...hope u can fix that cam choppiness.
[Nexus One Android Development] humercab:
I have problem with a2sd..I formated everything so it was clean install . And when I start a2sd install it says /system/bin/a2sd: line 73: /sd-ext/.a2sd: Read-only file system

chmod: /sd-ext/.a2sd: No such file or directory

I have 1giga ext4 partition.. What am I doing wrong?
[Nexus One Android Development] lkvn:
You may try a2sd xdata => this will move *everything* on the sd card this is not recommended because you may expect slowlyness. I did it on my phone, I have a 16gb class 4 sd card, with 4Gb ext-sd partition. It's smooth enouth for my use.
[Nexus One Android Development] lkvn:
make sure you ext-sd partition is ext4.

I had the same issue and resolved it when I've formatted my ext-sd partition with gparted...
[Nexus One Android Development] gregferns:
Hi. Do you use a 4gb sd-ext on your nexus one?
[Nexus One Android Development] lkvn:
yes !
[Nexus One Android Development] humercab:
I did try it. I formated my sd card (4gig) and made one FAT32 partition and 1gig EXT4 partiton and same. I formated card all to fat32 and made ext4 partition in CWM recovery. Same. I formated second partition to EXT2 and the same.... I'm a bit lost here :confused:
[Nexus One Android Development] lkvn:
My experience is that I've never been able to have a working ext-sd when formating it using CWM, so I pulled the sd card out of my phone, and formatted it using gparted on my desktop computer.
[Nexus One Android Development] humercab:
I just did it again using gparted in ubuntu..All the same. Is it normal that I don't have permissions for r/w on this partition? I cannot copy nothing on to it or create dir...
[Nexus One Android Development] gregferns:
Why don't you try formatting in 4ext recovery, that does the job well. No harm trying.
[Nexus One Android Development] humercab:
Great! I formated as ext4 again in 4ext recovery and now it is working..Txh

Yup, camera flickers almost always when launched for the first time. Once you exit and restart the app, it should be fine. Reg, the reboots, they are sporadic and difficult to predict.. Must be an exception somewhere.

I have problems with the Wifi Tether (Hotspot).

If the Phone is rebooted I can activate the hotspot after one minute it deactivates and I can't switch it on agian.

If I try it the hotspot swichs on for one second and goes off.
[Nexus One Android Development] rossikwan:
Thanks, this is really fast but ...

apps always stopped & apps couldn't installed in Play Store most of the time with invalid package file.

1. wipe all before flash

2. using m2sd, with app, cache, dalvik cache moved....

alogcat: http://justpaste.it/1sx6
[Nexus One Android Development] qxontic:
i tried m2sd a few times with different settings, it just didnt worked.

use the build in a2sd instead. i installed the rom as followed:

wipe everything except sd card

flash the rom

flash evervolv jb gapps (http://d-h.st/dLb) (for genie widget)

reboot

DO NOT set up your google account on first boot

run in terminal:

su
a2sd install
y
y
y

after reboot set up your google account

DO NOT use titanium backup or similar to restore your apps. i couldnt install any app from the play store after using tb.

you should have enough space for apps now ;)
[Nexus One Android Development] rossikwan:
Thanks, used back a2sd with the same step as yours.... and TB could only restore some old apps

Everything seems normal again. No more apps stopped. :good: And it's really fast...

Re: [ROM/4.2.1] [Jan 13 2013] VJ CM10.1 | Jelly Bean 4.2.1 - v4.5 for N1

I had no problems restoring from tb with all the above steps exactly. Are you restoring tb apps from another DIFFERENT Rom? If you restore from evervolv then no issues at all. But restoring apps backed up from another Rom may pose problems.
[Nexus One Android Development] Gablu:
1. If I get a call and don't pick it, when the call drops from the other end.. The phone freezes. I had to put my battery out to restart it again.

2. Secondly, If I click the Power button or the track ball the screen some times doesn't wake up rather the Nav keys wakes up only, after few tries i get to screen woken up.

Issue 1. UnSolved

Issue 2. Solved. (I changed the screen time as well to 30 secs from 15 secs, but i might think that it's more of a hardware Issue. I've a new kingston 8GB class 10 card. renewed my SIM card as well)

Other issues:

3. frequent Restarts are happening.

4. Wifi advance settings FC

5. Dsp manager equalizer is not working with headphones and speakers. At first it worked and soon I go for the custom preset equalizer, it lost the control.

Having said that. A very smooth JB experience so far on N1. Smooth transitions .. running ondemand governor default configurations.

Very good work.

Recommend me an I/O schedule.. ??

Hi,

Another perfect ROM!

for me it works very good in all the things i tried uptil now.

the only bugs i found are:

1. advanced wifi settings give FC. (i don't use it but i checked cause other had the issue, and indeed i have that too)

2. after i finish a call i noticed my phone is working pretty slow for about 2 minutes. i have noticed it whn i was listening to music on the bus and few people called me few times. after each hangup the music was lagish and the phonew wasn't responsive as always. after about 2 minutes it works well again.

thank you!
[Nexus One Android Development] jolinnard:
For me it's worse...

I've set it to 10% zRam.

I'm very lucky. My Nexus have 3 years old and power button it's working fine like first day ;)

:confused:

Placebo!!!!!!!!!!! (check https://code.google.com/p/android/issues/detail?id=42265)

:good:

With apps and dalvik to sd-ext all it's a bit worse, but I feel confortable right now!
[Nexus One Android Development] darkshino:
Check if you really get some swap, personally I activate zRam in "Performances" and realize it isn't enable though. I have to manually add a script in /system/etc/init.d to really activate it.
[Nexus One Android Development] jolinnard:
Yes, something it's happening with /system/etc/init.d/06handleswap script. But if you manually run it works!

figue ~ $ adb shell free -m | grep Swap
Swap: 0 0 0

figue ~ $ adb shell /system/etc/init.d/06handleswap
Setting up swapspace version 1, size = 42422272 bytes
vm.swappiness = 60

figue ~ $ adb shell free -m | grep Swap
Swap: 41428 0 41428

Where do you push your script?

Edit: Found it. Seems that "getprop persist.service.zram" it's not set early when system boots. So if you set it to a fix value it works.

I rewrite the script to check if persist.service.zram prop it's set. If it doesn't, then it looks to /data/.zram file. And if it doesn't exist it assume 18% (default).

Here it is:

#!/system/bin/sh
#
# handle zram
#
# First the script tries to parse persist.service.zram prop,
# if it's not set, it looks to /data/.zram file,
# if it doesn't exist, assume default (18% zram)
#

memtotal=$(free | grep Mem | awk '{print $2}')
zramprop=$(getprop persist.service.zram)
zramfile=/data/.zram

if [ "$zramprop" = "" ]; then
log -p e -t 02zram "persist.service.zram prop not initalized"
if [ -f $zramfile ]; then
zramprop=$(cat $zramfile)
log -p e -t 02zram "$zramfile found. Setting zram to ${zramprop}%"
else
log -p e -t 02zram "$zramfile file not found, falling back to default 18%"
zramprop=18
fi
fi
zramsize=$(($(($(($memtotal * $zramprop)) / 100)) * 1024))
zramblkdev=zram0

#echo memtotal $memtotal, zramprop $zramprop, zramsize $zramsize, zramblkdev $zramblkdev

echo $zramsize > /sys/block/zram0/disksize
busybox mkswap /dev/block/$zramblkdev
busybox swapon /dev/block/$zramblkdev && sysctl -w vm.swappiness=60

Push it to a new file into /system/etc/init.d and delete 06handleswap, or edit 06handleswap.

It requires execute permissions.

For example, to specify 10% of percentage by /data/.zram, simply do:

$ adb shell
root@android:/ # echo 10 > /data/.zram
[Nexus One Android Development] darkshino:
At the moment, I pushed those two scripts in /system/etc/init.d, then "chmod 750" and "chown root:shell" on both files.

06zram is to create a 48MB zram, the second one 98othertweaks is to tune cpufreq overclocking as this option seemed ignored at boot time, and random entropy, which is probably useless (just a try for me).
[Nexus One Android Development] jolinnard:
OK I see... I edit my early post with a script too. It parse a file to set the percentage (/data/.zram). It's very simple like yours.

Max freq it's another setting that it's not applied at boot.

I'm not sure that entropy values work better :laugh:

Some time ago I was testing to increase read cache to 2048 (/sys/devices/virtual/bdi/179:0/read_ahead_kb), but it seems that all it's worse... Did you try it?
[Nexus One Android Development] boypro25:
after I flash Rom, sometimes, My phone is auto reboot.

So how to fix that?

:(

my English is not good, I'm sorry everybody!
[Nexus One Android Development] darkshino:
Thanks for sharing your script, nice idea to create a simple script that parse a file in /data ;)

I'm using Mount2SD from dk_zero-cool. His script set read_ahead_kb already. He says a good value for general use is around 128kb. Larger values are useful if you use UMS to transfer big files to/from your sdcard from the computer. If not, a smallest value is better, else it would slow down a bit read of a lot of small files which is the general use when you use the ext4 partition for a2sd. I don't complain about this choice regarding performance, and I think this statement makes sense.
[Nexus One Android Development] jolinnard:
It could be for some app, or maybe a bad flash. What is your /system partition size?

Remember that this is a development thead, if you have some questions there are a general section or Q&A to post it ;)

[Nexus One Android Development] F i L:
Hello! I had this rom on my nexus one with a class 4 (the stock) sd-card. However I was experiencing some laggish performance and the known answer call lag issue. Yesterday I just changed my sd-card to a 16GB class 10 one, wiped/installed the rom and honestly its a total different experience! No lag at all in anything.

One thing: During the partitioning of my new sd-card using the 4Ext, there was an option about the swap size. Since I had enough space in my sd-card(16GB) I thought "why not" and I chose 512MB swap space. Is this rom compatible with swap? Because from Android System Info app I can't see anything about swap, and the ram size is still the same (max: 404). I have to admit that now the free (unused) ram seems much larger (there are times that the app reports up to 160mb of free ram!) but I am not sure why. Definitely the new high speed sd-card helps the rom to perform better but is the swap used by the rom?

Thanx!

PS: I read on the internet many contradictory opinions about the swap in android OS however I chose just to test it but again I am not sure what happened :P

Did you ever get this issue resolved? Does anyone else still experience this issue? My GPS always stays searching even if I let it search for over 30 minutes. I have also tried changing some settings using FasterGPS, but it still never gets a lock. The GPS icon just keeps blinking. I tried several different programs that use GPS. It used to work fine for me on previous ROMs. Any suggestions?

[Nexus One Android Development] Pdog911:
Sometimes the GPS status app can help. It seems like sometimes downloading new data helps or resetting the gps. It is kind of a crapshoot though. I have had troubles with the GPS for quite a while on several different roms. This one does not seem particularly worse or better.
[Nexus One Android Development] Toad:
I tried using the GPS Status & Toolbox app. I tried resetting and redownloading A-GPS data. It just keeps saying "Looking for GPS location." Is there another app I should be using or something else I should try?

If you are only referring to Exchange device policy, you may want to give "Enhanced Email" a try. There, you have the option to disable device policy enforcement. (Or Touchdown, which only enforces app-specific device lock policy)

If you are referring to corporate wifi device policy you may want to try Evervolv's JB ROM, which I'm running on my N1. There, I'm not required to lock my device due to WIFI policy while I am on my stock Samsung Galaxy S3...

The a2sd on this rom is horrific. I've tried 10x now. 260/10 BR, 16GB sd freshly formatted to 2GB/256MB. Fresh wipe on everything, fresh installs. Upgrade to ext4, install yyy.

Internal partition still fills after ~10 small apps...
[Nexus One Android Development] cnossa:
I've managed a2sd to work only after using a2sd xdata (Y Y) as refered on previous posts.
[Nexus One Android Development] jhsiao36:
Only way I got it to work was to install A2SDGUI and then make sure that under A2SD Settings: Apps are on SD and under Dalvik: Dalvik Cache on SD-EXT (and then Move!).
[Nexus One Android Development] Toad:
Same here. I had to use a2sd xdata otherwise I had space errors (but only with certain apps).
[Nexus One Android Development] dogiedogie:
When I tried that last time it went mental, would perform effectively a factory reset of system every time restarted.

Installed but it says not rooted, no ext or no a2sd scripts. I have all 3 :/
[Nexus One Android Development] jhsiao36:
Sorry, ignore A2SDGUI for now - I had a brain meltdown and thought you had DarkTermors' A2SD installed.

The other thing I can think of is that the dalvik cache is filling up quickly.

After you installed a2sd, I would suggest installing a few apps until you get low on internal space, and then in terminal emu, type a2sd cachesdreset.

This will move dalvik cache to ext3 (or 4) and erase the current contents, and reboot your phone.

Hopefully after that, you should have more internal space. If you install more apps after that, and find that your internal space is filling up quickly again, try repeating.

The reason I execute the cachesdreset after installing a few apps is because sometimes (for unknown reasons) I found that the command does not do anything after a clean rom (and a2sd) install.

Good luck!

---------- Post added at 02:02 PM ---------- Previous post was at 01:48 PM ----------

I've tried the a2sd xdata and have gotten it to work - my nexus reported .98 GB of internal storage (I set ext4 to 1 GB) and I was able to install about 700 MB worth of apps on this rom (something you probably cannot do with a2sd install). However, just remember, you need a class 6 (preferably 10) for this, and even so I found it to be extremely unstable, as twice now, a reboot corrupted the partition and all my apps were wiped.
[Nexus One Android Development] dogiedogie:
Was a2sd clearcache what you meant?

Interestingly it said "clearing /data/dalviccache" or something along those lines to suggest it was still on the /data partition, unless I'm not understanding the naming scheme. No its not given me any additional internal space. Stuck at 25 at which some apps will install, won't install.
