give it a shot. I'm on a Rogers ROM, otherwise I would!

Anybody know if we can do a backup before upgrading then wipe flash and re-flash just our userdata?
[G1 Android Development] jroid:
from what I hear about compache is that it increases the phone's RAM thus, not needing the swap. this could just help make hero run much more smoothly if we can get it to work.
[G1 Android Development] alritewhadeva:
We'll see what happens :) Which one is better though? Swap or compache
[G1 Android Development] johnnylicious:
rm -r /system/sd/*

^ thats the correct code.
[G1 Android Development] xREVOx:
compcache doesn't increase the ram per say... it just uses your ram for the swap file.. it compresses the swap... supposedly compressing and uncompressing to internal memory is still faster than swapping to the SD Card.
[G1 Android Development] coolbho3000:
I tried pushing the modules to my phone, but I get an exec format error. :(
[G1 Android Development] jroid:
right, i found it with a search. I went of the top of my head on that one. what i'll do is backup my data and apps, then go to console wipe ext2, wipe, then re-flash.. im really hoping this works
[G1 Android Development] rickyuknowme:
how much faster is superlight compare to the reguler 2.7?
[G1 Android Development] illusive817:
Calnder not syncing with google?

is there anyway to get calender to sync up with google?

everything else works amazingly

i would like to get calender and bluetooth working tho
[G1 Android Development] xREVOx:
compcache won't degrade your sdcard. it doesn't even use it.
[G1 Android Development] alritewhadeva:
so why aren't we using it yet?
[G1 Android Development] xREVOx:
did you great the directory /system/sd/modules?
[G1 Android Development] alritewhadeva:
nandroid is your friend
[G1 Android Development] xREVOx:
newer method. not all kernels support it yet.
[G1 Android Development] coolbho3000:
Yeah, they're all in there. I even chmodded the modules to be sure.
[G1 Android Development] alritewhadeva:
oh i see. We'll see if JAC incorporates it sooner or later. Any big performance differences?
[G1 Android Development] xREVOx:
assuming you have all the right files in the right places, can you run this from terminal?

su

insmod /system/sd/modules/xvmalloc.ko;

insmod /system/sd/modules/ramzswap.ko disksize_kb=32000;

busybox mknod /dev/ramzswap0 b 253 0;

ok guy i'm a nubie when it comes to android rom flashing, and i been doin the research on the how to stuff but its a few post when i here about the bugs in stuff, and i know you guys have come along way from the non bluetooth and wifi days, but i just have a few questions ( and i have been reading posts for about the past week) if you guy dont mind answering please

in jachero 2.63 are what are the mms/sms problems? and what are some other known issues? please that would
[G1 Android Development] jroid:
man i wiped the ext2, wiped data, and reflashed and mms/sms is STILL forceclosing. going back to cyan. I need my texts hero isnt that worth it
[G1 Android Development] coolbho3000:
That's actually what I tried first.

Maybe it doesn't work with the 2.6.29 in JACHero, only Cyanogen? Anyone know how I can swap kernels (is it just as simple as flashing a different boot.img)?
[G1 Android Development] alritewhadeva:
Reformat your sdcard if you want hero badly :)
[G1 Android Development] xREVOx:
I'm using soulife's rogers rom. I notice a slight improvement, but Rogers Roms are very fast anyways.
[G1 Android Development] alritewhadeva:
Bluetooth and LED do not work. Latest version is 2.7.1 and there are only minor mms/sms issues. 9/10 should be sent + recieved.
[G1 Android Development] MortICi:
It won't work cause lzo_compress.ko and lzo_decompress.ko need to be modprobed, but it seems that you can't modprobe in this build get a cannot parse modules.dep error

Running modprobe by it self results in:

# modprobe
modprobe: cannot parse modules.dep
[G1 Android Development] xREVOx:
which line gave you the error?
[G1 Android Development] VGPOP:
This newer ROM is noticeably faster.

The clock widget does not show the weather. Was it removed?

How do I get it back? (I know, I know, I should read the thread, was hoping for a quick answer).
[G1 Android Development] MortICi:
insmod errors out becuase the dependencies have not been met. Cyano's kernel has lzo_compress/decompress built in. This kernel does not. However they can be modprobed, unfortuantely it seems that the kernel was somehow fudged on build, or busybox is broken.
[G1 Android Development] coolbho3000:
I think MortiCi's explanation makes sense.

It won't insmod either module because of "exec format error."

I'm now looking to switch Cyanogen's 2.6.29 kernel into JACHero...
[G1 Android Development] alritewhadeva:
Delete that clock and add it back
[G1 Android Development] xREVOx:
Yeah I read his explaination after I posted mine.
[G1 Android Development] jroid:
naaa ive done enough of re-partitioning. im done with those days. i like hero alot BUT ive found a refuge which is cyan. hero isnt worth re-partitioning my sd card over. just when i thought I could finally be able to run hero, sms out of ALL things has to be the one to screw everything up when ive never had this issue before. goodness man
[G1 Android Development] VGPOP:
Yeah, I did that before posting, but it still no weather.
[G1 Android Development] MortICi:
To do that i think you should only need to flash boot.img since it contains the kernel, however this might break things. Cyano's kernel doesn't support multitouch as well.

I think busybox is broken, a newer or older version would need to be pushed with modprobe fixed.

Then i can test the lzo_compress.ko and lzo_decompress.ko, and if were lucky it will insmod the rest.
[G1 Android Development] alritewhadeva:
It should ask you what city you want.
[G1 Android Development] jroid:
edit: sms does work for me thru chomp; but mms doesn't work. I can deal with not using stock sms app cuz i'll just use chomp but man I need that mms...grr.
[G1 Android Development] VGPOP:
The current city button is not working, then

I had to manually find Orlando, FL. And that's the only way it showed weather.

GPS was on.
[G1 Android Development] alritewhadeva:
Try on a 2g network. For some reason, it won't find your location if you're on 3g or GPS
[G1 Android Development] VGPOP:
I have WI-FI turned on.

It's a known issue then? 3G/GPS not working for the weather widget?
[G1 Android Development] jawash22:
I would re-download the entire ROM. Maybe, for some reason, it didn't give you a complete download. Can't hurt to try.
[G1 Android Development] BlackElvis79:
Start a flash, then take the battery out while it's still flashing. It'll turn off, and you won't be able to turn it back on.
[G1 Android Development] nolimit78:
Yeah I am having the same SMS/MMS problem as everyone else. Oddly enough I didn't have a problem until I flashed to 2.7.1. I am using ext3. Does anyone know the command to format the drive using the phone? Thanks!
[G1 Android Development] jroid:
im gonna try to remove the sms app and re-install via adb. where is it that we have the apps saved on /system/sd/app_s?? hopefully this will fix it
[G1 Android Development] stevemartin1991:
Just flashed amazingly fast only problem messages.apk file keeps forceclosing. I don't have adb so how can I sort this issue......thanks for any replies. Steve
[G1 Android Development] DMaverick50:
so are there people who can send /receive mms or this accross the board? And what is the sms problem people are complaiing about? thanks
[G1 Android Development] alritewhadeva:
believe so. Just look back a coupe of hundred pages :D
[G1 Android Development] jroid:
i'm trying to resolve this issue right now.
[G1 Android Development] nolimit78:
It's really a hit or miss kind of problem. Like I said I was able to use SMS/MMS using 2.6.4 but when I updated to 2.7 the SMS/MMS FC's when you try to open it. I've seen that reformating ext2/3 could help or to repush the messages.apk but I'd like to do it using my phone rather than ADB. For some reason ADB won't run on my work computer.. (haha)
[G1 Android Development] zbraniecki:
when I click on Messages it crashes, and ddms reports this: http://pastebin.mozilla.org/662954
[G1 Android Development] markimar:
WOW! This build kicks butt!

You would think this was a stock ROM. No issues upgrading from 2.63r.

Did a wipe but didn't touch my sd card.

Quick question though. It says lucid script is included but does it run automatically?

I also noticed when. Upgrading apps or uninstallimg the buttons don't match up with the text. Some of the words are behind the buttons.

Great work guys! I truly have to day. This is the fastest Rom yet.
[G1 Android Development] alritewhadeva:
Lucid script does many things for you. Search :)
[G1 Android Development] roguespy0:
I had the same issue.I wasnt able to send any mms it would jsut force close,all i did was take the mms.apk from the prev jac hero and installed it. I used eos apk installer from the market and it worked. That fixed my issue,no more force close issues.
[G1 Android Development] justanothercrowd:
2.72 is out

Changes

-Rosie.apk Modifications to fix Open folder View in Rosie

-Wallpaper by dom2864

GPS should be working since 2.7.1
[G1 Android Development] alritewhadeva:
The man lives :) Lol thanks!
[G1 Android Development] bobbybooshay:
2.7.1 is rad.

it is actually a useable build (as in faster than most hero's)

while text messaging with one contact and receiving a text from another (in top notification bar) upon clicking on the new text message notification from the pull-down shade, i get a blank. it looks like all it does is clear the notification from the pull-down but doesnt do anything afterwards. i just have to manually find that message from the list to reply.
[G1 Android Development] coolbho3000:
Can we please see a version with Cyanogen's kernel so Compcache can commence? :)
[G1 Android Development] kokob42:
Messages

Had same problem formated the drives, installed 2.71 all is good.
[G1 Android Development] dskyers:
actully

it actully does not matter what software you have on the phone i replaced mines last year after i got it.. thats when j.f 1.5 was out and i was excited to just have done something to the fun lol... i am running 2.7.1 and i ave no problems aside from auto rotate witch we can live with out it all works super fast havent had any issues thanks for doing what i can not..... now my dream has finally became a hero
[G1 Android Development] robpet2:
Flashed the newest version this morning with no issues. Sms. Works fine. Downloaded from the second link with no problems.
[G1 Android Development] stevemartin1991:
@ jac has 2.72 solved the messages.apk force close?
[G1 Android Development] jroid:
fixed it. what i did was removed the mms.apk and mms.odex and just pushed mms.apk and all is well. gonna send a pic now to confirm
[G1 Android Development] SolemnWishing:
You have got to be kidding, I just flashed 2.7.1 and 2.7.2 comes out.. ahaha

also, anyone noticing that the email notifications only work every "once" in a while?
[G1 Android Development] Shaquiel Harris:
i sware JAC imma kick ur ass i was just writing a comment about to post how good this damn rom is now im about to flash again LOL.
[G1 Android Development] VGPOP:
I just want to re-confirm this.

Every time there is a new version, you need to wipe your FAT32/Ext2/Linux-swap and re-do it again?

Or can you just do a wipe and flash newest version?
[G1 Android Development] MortICi:
Ok its not a busybox issue. It seems that the kernel was built without modules (depmod wasn't run?).

Unfortunately modprobe has no force option in busybox 1.8.1 :(
[G1 Android Development] imfloflo:
can't install market app on 2.71 can somebody tellme what is the commande chown 755 path i must enter to allow or i will just flash 2.7.2
[G1 Android Development] sullitf:
Best bet is usually to wipe the ext2, but you shouldn't need to mess with the FAT32 or Linux-swap partitions. Its only really necessary to do a complete ripe/repartition of your SD card if you get strange problems after flashing, force closes etc.
[G1 Android Development] bobbybooshay:
anyone know where the link is that teaches one to wipe their ext partition without messing with the other partitions?

and what would be the best way to go from .7.1 to .7.2? would i have to wipe?(i hope not)
[G1 Android Development] VGPOP:
Can I still wipe ext2 with the console commands in the beginning of the thread?

Can I just type....(in console, commands in bold)

#parted /dev/block/mmcblk0

rm 2 (this is ext2 partition)

mkpartfs primary ext2 600 984

end

#upgrade_fs
[G1 Android Development] stevemartin1991:
I just flashed. Worked fine but did need 2 resign into Google. Messages keeps fc tho :(
[G1 Android Development] sullitf:
I wouldn't even go that far. The reason you need to wipe is just to remove all the old .apk and .odex files. you can do the following and not have to redo the partition.

(from recovery terminal)

# mount /system/sd

# rm -r /system/sd/*

# umount /system/sd

# recovery

That should clean out ur ext2 partition and return you to recovery. Again, if you do flash and experience some really strange errors you may want to redo all the partitions with the #parted commands.
[G1 Android Development] sullitf:
If you didn't wipe before flashing I'd recommend wiping your ext2 as well as doing the alt+w wipe from recovery. Flash 2.7.2 after that, hopefully that'll fix it.
[G1 Android Development] robpet2:
Flashed the 2.7 then 2.71 version this morning, coming from cyanogen 3.6.5, with modded swap, and had no issues, the rom wipes the data automatically.. when i did the upgrade, from2.7 due to the force close issue from last night, havent had a force close error except for when tryin to acces youmail app.. when using cyanogens recovery img, use the option for repair filesystem before rebooting the phone.. sms and mms works fine.. only issue i had was the camera shows vertical as landscape on the rotation, but i can deal with that...
[G1 Android Development] rpmccormick:
I'm confused. I thought one of the advantages of using Apps2SD was that you did not need to reinstall all of your apps after a FW upgrade.

Question: What is the best way to upgrade from 2.6x to 2.7x, and restore all of your settings like...

1) SMS/MMS

2) Everything under Settings & Spare Parts

3) Programs + Program Settings

4) Home Layout (Wigets/Icons)

Do I really have to manually search for, download, install, configure, and setup the icon in home for every one of my 50 or so apps everytime I flash a new firmware? I was hoping Apps2SD would save me at least some of that work.

Does Backup for Root Users work for at least SMS in Hero? It didn't when I backed up JF and tried to restore in JAC 2.6x

Also, I know that BT is being worked on for Hero, but is anyone working on the LED and/or the Camera Button? I would love an app that just let me set the camera button to run any program. It just does nothing in Hero like BT and the LED.
[G1 Android Development] teknically:
2.72 full

I was getting an acore fc when opening dialer/send, so I wipe and reloaded... now i am able to open dailer/phone but it sits there not displaying anything and then closes with no error...

any ideas... anyone?
[G1 Android Development] sullitf:
You can always try to flash without a wipe. The worst that will happen is you will waste a little time and end up having to wipe the phone and ext2 and reflash.

Just depends on if its worth it to you to try or not. Personally I've found that I tend to have issues if I don't wipe my ext2 and phone before flashing a new version, but that may not be the case for everyone or for every ROM.

EDIT: When I do wipe and flash a new ROM the market always shows all of my previously installed apps in the My Downloads section. After flashing the first thing I do is open up the market and reinstall everything. Just make sure you install all of them when you first go to the My Downloads section because it only holds on to the previously installed apps once. If you open My Downloads, go back to market home, and then back to My Downloads it will be empty (or include only what you have installed after the flash)
[G1 Android Development] chesh420:
When you wipe your ext2 partition, is that removing all the apps you d/led from the market too, or are those stored on a different partition?
[G1 Android Development] teknically:
All are on your ext2/3 partition... So yes all gone... just save em
[G1 Android Development] stevemartin1991:
Tried that its still force closing wtf??????? Any ideas guys? Steve
[G1 Android Development] chesh420:
Ya, use adb to remove the old MMS.apk file and repush one back. Seemed to work for another user a couple of pages back
[G1 Android Development] stevemartin1991:
Erm I don't have adb so that's no use :( how could I do it thru terminal?
[G1 Android Development] KennySmoothx:
You might have to wait, Reboot phone. If not then re-flash. The key here is to be patient and to let it do its thing.

BTW it might bootloop once. Thats normal just leave it alone. If its by its third bootloop. Wipe and re-flash again.
[G1 Android Development] CPR123:
Flash 2.4 with no issues and so far it's quite smooth. Coming from 2.3.6 Just wipe and flash
[G1 Android Development] KennySmoothx:
You always should wipe. If not you have a higher chance of getting stuck in a bootloop.
[G1 Android Development] krazyconejo:
True, but I had just flashed 2.3.6 yesterday and didnt wanted to wipe again lol
[G1 Android Development] Lou2serious:
Although I have a class 6 card, I'm waiting on the slow version, I just feel better with app_s staying internal. Previous builds always corrupted my ext partition.
[G1 Android Development] KennySmoothx:
Try it out then lol, you really have nothing to lose. If you do get stuck in a bootloop then wipe.
[G1 Android Development] alexjzim:
i flashed mine, and swapper was not installed. not rlly a big deal, since we can install ourselves, but just wanna give every1 the headsup

unless its only me and my update was corrupted
[G1 Android Development] krazyconejo:
Too late I just wiped am already installing 2.4 lol
[G1 Android Development] SolemnWishing:
Actually, for some reason when flashing JAC's updates, it almost feels like it wipes by itself, as we have to go through the sign in process, reinstall some apps not on the SD card, and replace all our stuff on the homescreen..
[G1 Android Development] live_in_the_sky06:
I just wiped and flashed. had no issues whatsoever. I think it bootlooped once but I believe thats normal. Its running quite smoothly.
[G1 Android Development] komplexicpnoi:
im flashing right now.. i never said this..

but i just need to get this out.. i love u jac.. ;]
[G1 Android Development] Dror520:
I just wiped and flashed and when I boot I get a force close of the setup wizard ... should I reflash?
[G1 Android Development] ttownboy84:
swapper came with the build, works like a champ
[G1 Android Development] chordmasta:
Can anyone confirm the status of SMS?

What I mean is

ARE WE RECEIVING THEM YET?

I've missed like 30 texts in the last two days, considering a flash back to Rogers if this doesn't resolve it.

Thanks
[G1 Android Development] domanads2k4:
Out of all the builds I tried (all of them) I never missed any
[G1 Android Development] KennySmoothx:
Im receiving all of them, then again I haven't had an issue since like 2.2.1

And 2.4 running very smoothly. Flashed and had one bootloop which is normal and everything is working great.
[G1 Android Development] komplexicpnoi:
lmfao i was watching a promotional vid for the htc hero and it went

htc ->> then hero

so i assumed this. haha it doesnt bother me, but i found it a little funny to think the bootup went backwards

What's the kernel info under about phone?
[G1 Android Development] teknically:
Once its mounted, do a

su

cd /media/XXX (ext2/3)

cd /app_s

cp dir with new mms/MMS.apk .

overwrite
[G1 Android Development] chesh420:
you'd have to extract the MMS.apk from the rom, copy it to your SD, remount your system as r/w, delete the old MMS.apk from /system/sd (I believe), and then copy the one from your SD card back. You might need to chmod and chown it too.
[G1 Android Development] teknically:

Is anyone having trouble mounting their sdcard in JACHero 2.7.1?

It keeps dismounting when I try to mount it... did I miss something?

Thanx.
[G1 Android Development] Deathwish238:
I just came over from The Dude's Cupcake. I updated the radio and spl and partitioned the sdcard as the guide states.

However, my phone currently says it only has 64 MB of internal memory. That's not right is it? I used to have over 900 MB.

Also, does Swapper make a worthwhile speed boost?
[G1 Android Development] chesh420:
Once again, do not use swapper. We use linux-swap partitions now. Follow the instructions in the first post and you'll be fine. If you partition your card the way it says to, swap will be automatically enabled upon a reboot with a rom that supports it.
[G1 Android Development] jugg2000:
Nevermind... I figured it out.
[G1 Android Development] teknically:
Mine has always shown JUST the phones internal... (even though i have 450M more) ... its fine .... Swapper is sweet, but DO NOT USE in Jacs new builds
[G1 Android Development] alritewhadeva:
Dude uses Unionfs and it reads memory on ext partition. This uses bind mounts and symlinks reads memory thats internal. Yes it makes the worthwhile boost
[G1 Android Development] PsychoKilla666:
Fast but utterly useless in current state without SMS, pls fix for mere mortals
[G1 Android Development] sullitf:
Haven't used the Dude's rom in a while but it sounds like he's using UnionFS, which basically tricks the phone into thinking that a partition on your SD card is part of the phone's physical memory. That is why it used to say 900MB free.

64MB is more normal, I think the original rom from T-mobile gave something like 72MB free if I remember correctly.
[G1 Android Development] jroid:
to fix mms/sms u have to delete the Mms.apk AND the Mms.odex then re-install the new Mms.apk for it to work.. I tried just deleting/re-installing Mms.apk and I still got the fc. deleted the .odex and it worked.
[G1 Android Development] g2crx:
so delete both then re add the same mms.apk that you deleted/
[G1 Android Development] chesh420:
Good to hear ya got it working jroid :)
[G1 Android Development] q426669:
Do Nandroid backups restore your apps?

I used the recovery restore after making a backup before flashing from 2.63 to 1.71. It restored my settings, wallpapers, folders, and shortcuts, but none of the actual apps seemed to be installed.

Am I missing a step? I read the Nandroid thread, and didn't see this mentioned, and I scanned this thread with search, and didn't see anything, but I probably missed it somewhere.

Thanks for the time & help everyone here @ XDA!
[G1 Android Development] nolimit78:
Can you provide steps for this using the phone?
[G1 Android Development] teknically:
I copied all from my ext2/3 and saved it as well... seeing when you wipe your ext2/3 it removes everything including apps ;)
[G1 Android Development] q426669:
....D'OH....
[G1 Android Development] jroid:
yes correct. i'd pull the Mms.apk from a freshly dl'ed build just to be on the safe side. thats what I did.
[G1 Android Development] teknically:
look back like 2-3 pages ;)
[G1 Android Development] jroid:
thanxz man, yea right after I fixed it I installed .72 and the changes remained inact. sending sms/mms now perfectly fine :)
[G1 Android Development] Deathwish238:
Okay cool, this is why I asked before I installed swapper :)

Any idea about my internal memory showing only 64 MB available?

Edit: lol okay you all already answered my memory question...you guys reply way too quickly...more than a page of posts went by while replying :)
