I was wondering if anyone else was running into the problem I'm having, and if it has been covered before and I missed it in the search box earlier I apologize. I just recently tried to upgrade to JACHero2.6 and my market app (most important) along with several others are missing. The apps are automatically installed on all my other roms, it is only with hero that I end up missing alot of apps. I have a correctly formatted SD card and I did a wipe before I installed this and tried the whole process twice. If I am forgetting to do something special prior to installation or afterwards please let me know!!

you may have gotten a bad download. try redownloading it again. do you have 3 partition (fat32 ext2/3 linux-swap) if not i suggest that for jac's 2.63 also make sure you check file extensions in recovery screen. hopefully this helps
Yes I have my card that exact format and I tried using the filesystem checker in the recovery screen it said filesystem check was complete!! I'll try doing the whole process over again but I'm not sure how that would help, and it is sad too this is the best damn hero rom i've tested to date, its fast as hell!! If it weren't for my apps not being here i wouldn't be planning on a future rom update in the near future or until some big release happens.
make sure you always check md5 sum of all your hero build download
you could of had a damaged downloaded rom and this could affect your rom.
Just tried to download a fresh copy of the rom, checked to make sure my sd card was working properly, wiped and re-flashed yet my market app and the same apps I was missing before is still missing. It should be included that apps on my ext2 were coming back like they should be just not all of them, and not a few apps that I thought should be included with the rom. Is there anything I should check that I may not have yet?
I would use Root Explorer to check if the apk files are still under system/sd/app if they aren't... well, there's no way you're going to see them again unless you re-install them. You can also look under system/sd/app_s if that's there. Other than that, if you can't find it, it's not there. (If you know the exact name of the file or at least part of the apk file name, under terminal type: find "file name" (w/o quotes ofc)
You can add wildcards (*) if you don't know the exact name of the file. If the apk file is still there... well... let's just see if its there first.
I checked using terminal, I typed "vending.apk" and tried to check the dir's you specified for the apks. If they are there I can't find them, although I am a bit limited as terminal is the only app that came loaded with which to check for files. If the apk files are indeed not there then why would the apps install on their own without a problem on any other build but hero??? I must be doing something wrong right? I am open to any suggestions at this point, even using a different rom to check for something, my goal is to have this rom flashed with my apps working soon!
heres the vending.apk from jachero 2.63 you can try and adb push it to /system/sd/app_s and see if it works.
Thanks, I'll try pushing that over but I'm still worried about the rest of the apps I'm missing. Would there be anything else I could try to make it possibly fix all the missing apps? What could be causing this problem in the first place? I did notice that my sd card has an ext2 rather than ext3 part, will that cause all of this to happen? I'm still pretty lost on this. I tried going back to another rom just to make sure my apps would still all pull up correctly, and they did so it has to be something related to this most recent build of jachero, or something
welcome to the club my friend (-;
i have the exact same problem and noone was able to help me yet.
It must have something to do with Jacs apps2sd method. i read some tweets between him and cyanogen that it might be a little 'rough'.
however - it's always the same apps that are missing, in my case it's (badly enough) launcher.apk AND rosie.apk which pretty much means that i can't solve it.
i also tried everything i could with ADB - without luck. I somehow have the feeling that theres something staying on the phone even when wiping and formatting.... I'll check this through ADB this evening.
look @ my recent posts:
http://forum.xda-developers.com/search_rop.php?searchid=25731882
for previous moaning from myself ( (-; ) and discussion with others in the JACthread. Basically the last 15 - 20 posts are about nothing else (-;
I will also do some logcating today - i've already seen the errors through install (rosie.apk couldn't be parsed etc) but i forgot to save it (and the command promt only saves 100 lines or something)

I have used AndExplorer and put the APK's in the sys/sd/apps and it all worked fine. Very easy to do if you don't know how to push, just reboot after.

You don't need to have the myfaves app for you myfave minutes to work. You are still calling them for free regardless if you have the icon or myfave compatible phone or whatever. If you want to manage the people just log on to mytmobile.com and make the changes there.
Hmmmmmmmm . I never realized thanks for pointing that out TurboTsi.

open up your copy of the build and check in system/app_s to see if the .apks are even in the build. if pushing the vending.apk works i dont mind posting the other ones you are missing if you want to pm me or something
Just tried opening the update.zip file and verified that all the apks are there. Which makes me wonder what exactly is up. Im thinking it could be an apps2sd issue, like what was said above. I didnt have this problem with older hero roms that i can remember. TBH I could try pushing apps with adb but that wouldn't bring back my other 3rd party apps floating in ext2 limbo. So I'm out of ideas ;(

try going to the recovery console and entering upgrade_fs and that will change your ext2 to ext3 and see if wiping and flashing change anything. also if you have root explorer you can check your /system/sd folder to see if all of your third party apps are there
Just tried upgrade_fs and it gave me a "unable to allocate block" I noticed there is little if any room left on the ext2 partition. Would that cause all of this? If not would it be worth a shot to resize the partition and give it more space from my fat32 then try to upgrade wipe reload again?
If you're out of ideas, then I would attempt to resize first (but backup your fat32 first) and then see if that solves it, if not, then I would format, wipe, and update...
but are you sure those 3rd party apps are not there? Try using Root Explorer to determine if the 3rd Party Apps are there, if they are, just pull them to your sdcard and try installing them again with ASTRO or something like that.
SOrry Guys Forgot 2 mention earlier. I moved To Xperia Mini Pro, So any1 else can take over and help PPL here taking hell outta there explorer
How to:
1. Download the files - "HTC Pico_Recovery,Boot with ext 2 3 4 support" , "BCM4330.KO" "superuser" from Below link,
"Superuser.zip" - http://www.4shared.com/file/KalrHXNj/Superuser.html
"Bcm4330.ko" - http://www.4shared.com/file/GbW0ZtaT/bcm4330.html
"HTC Pico_Recovery,Boot with ext 2 3 4 support" - http://www.4shared.com/zip/920-kXYc/HTC_Pico_RecoveryBoot_with_ext.html
2. Extract "HTC Pico_Recovery,Boot with ext 2 3 4 support" somewhere. say: desktop or some drive, copy "BCM4330.ko" onto ur adb "Tools" folder. Copy superuser.zip to ur Sdcard.
3. connect ur "Htc explorer(Pico) via USB" and open "recovery.bat from the folder u just extracted.
4. Wait relax, and watch ur device getting new underGarments. now as the time pass the "command Prompt" which just opened after opening "recovery.bat'' will show "adb reboot recovery" as the device boots to recovery, u will given new menu with blue fonts.
5. Now in recovery go to "Mount & Storage" and select "mount /system" with device connect via USB
6. I presume u have adb already setup on ur pc/laptop. Open "CMD" and type.
HTML:
adb shell mv -f /system/lib/modules/bcm4330.ko /system/lib/modules/bcm4330.bak
adb push /full/path/to/bcm4330.ko /system/lib/modules/bcm4330.ko
7. Now, select "unmount /system" from recovery menu (from where u earlier mounted /system)
8. select "goback" from below. now go to "install zip from SDcard. and and slect first open (which says choose zip from sdcard, or somthing like this). find the "superuser.zip" which u copied to ur sdcard and flash by selecting it.
9. Now if flashing goes smooth and it says "install zip from sd complete" then reboot ur device and enjoy.
For getting more space on ur device, download "link2sd"
For link2sd to work, i have attached tutorial for this (which i found by googleing) in Jpeg format (picture)
after getting link2sd to work , u can link the apps to sdcard and save more on device.
there is another option for getting more space on device.
Just download "terminal emulator" from market. pls note: u need to be rooted for this.
and give su permission to the app when prompted.
just enter
HTML:
su
pm setInstallLocation 2
now u will be taken to the next line and thats all
all ur apps will be installed to sdcard automatically. please note: when installing widgets, pls move them back to ur phone memory as they dont work on sdcard
Suggestion: You can pm me if you have some confusions or facing some problems rather than going some where else. I am always happy to help and there for the android community

Hey jitin02,
Thanks a lot for the post... But here are some changes I had to do to root my phone.
a. To install recovery:
The bat file kept waiting for the device infinitely. I just manually ran the two fastboot commands and the reboot command to setup recovery.
b. Copying superuser files:
Your method of extracting the zip file and then pushing them over to the /system directory will surely not work on windows systems, especially FAT32 file system computer, su file will not have executable rights when its copied into the dir.
right way is
copy superuser.zip to sdcard
boot into recovery
choose install from a zip option and point to that zip
Thanks for the post!
WIFI error and solution!!
rooted the phone manually with .cmd and then installed .zip from sd card.
when rebooting no wifi connection (error) and then formated using recovery but it didnt reboot (supose i have no rom installed now =$) how can i install another one, is there any for explorer?
any compatible rom would be fine for the time being.. =S

Unfortunately I bricked mine too. Oddly everything was fine for a while. Until it starting giving a wi-fi error and after that I tried to fix it with a reset and after doesn't go any further than the HTC logo. Any thoughts in how to bypass this other than flashing a new rom? I kinda liked my stock and didn't backup.

install it through recovery after wiping all cache and memory (recovery option)
everything works perfect, you have to install android market separatelly and reboot for it to work (at least me). Full reboot (untick the fast reboot from settings)
I am preparing a custom rom with preinstalled apps and without the chinese ones, i will be posting it soon.
I have a good news for HTC Explorer users'. My friend, he rooted it successfully. I'll post a translator tutorials about it for u all soon.

The custom rom is ok so far... still I am kind of a noob. Or feel like one. Is there a way to install other languages to that rom, specially the systemlanguage? and how to customize the rom?
Sorry for asking dump questions
Just figred, after I installed Market, and try to install an app, crashes. telling me the process has endet unexpected. :-(
Should have stayed with my original... anyone has a backup of an original rom?

I didn't find any ROM but that one, managed to make android market work by rebooting the phone (full reboot, untick the fast reboot option)
dont know how to add new languaje (if possible)
to modify ROMs just eliminate the .apk you want from system/app inside the zip and add any you want, I just modified mine and added like 15 different apps (file explorer, Copilot, android market, music player, adobe flash...) and doesn't use any memory (just available ROM) you have around 50mb free . once you install it look for available memory left with programs like APPS2ROM (it doesn't work in our HTC but helps me see ROM memory left).
i am going to try now to add an app to ROM memory by just creating a .zip file with /system/app folders and the .APK in it, let see if it works
Yes I figured now, you have to reboot the phone. Works fine now. Already made a clean backup.
Ive seen a file which has many apps listed and SHA1 keys in it. hats why I am asking for howto cook your own rom. Let me know if it worked. Would be great if I could add and remove some stuff

I am afraid it doesn´t, ("Installation aborted" message in Recovery). I will look for a diferent way to do it, not as simple as making a .zip file with "system/app/**.apk"
You can still uninstall them from rom memory using apps like "rom uninstaller" in andoid market
EDIT: found a way around it , just add the .apk inside "/system/app" in the "superuser.zip" found in the first post
http://www.4shared.com/file/KalrHXNj/Superuser.html
you already have this app in your phone so there is no problem in reinstalling it everytime you like on top of it (it even is the "pro version" of superuser, not the one on the custom ROM)
everything perfect
just note that no ALL of the apps work perfectly in the ROM memory, some crashed when opening them and had to uninstall them using "rom uninstaller" and install them manually
(I found just 2 small ones)
Yes while experimenting I found rom uninstaller too. and I managed to get rid of Sense 3.5 and some other stuff.
I installed GO Launcher EX instead and it runs alo better and faster than Sense.
Even this is my first Droid, I love it. I will make some Screenshots of it as soon I am dne with work.
I thank XDA and all users for the great work. Now I need to figure out if there is a way to install more languages.
For all PMing me... Scroll up to find the ROM

How/When did you do the back up. The guide I pointed you to - Heimdall One-Click For Dummies - doesn't reference a back up. Also, I assume your music was saved to your sd card. Are you sure it is not still on your sd card?
i used the first guide that u to me to use i download cwm5+voodoo lagfix, valhalla-black and i love it so far and now im bout to flash thunderbolt v2.77 i had valhalla-final but like v-black just cause i love colors on disrespect so once again thank you

The soft reboot is likely because you need to go in settings - tweaks - lockscreens and select a custom app.
Maybe connect your phone or sd card to your computer and look on it to see if your music is still there. I don't use stock file manager (use might download a root explorer like Super Manager from tbe market), but if you open it you are likely opening directly into the root of your sd card. Maybe explain that issue more and I can try and help.
Also, there is a VB Q & A thread that you may browse as it has a ton of answers to issues people have had.
Hello community, I just registered here and this is my fist post on this forum. First of all, I've solved many of my problems right here on this forum, and I am amazed how much you guys know, Not only that you are all gathered here, but your willingness to help complete stranger all around the world.
That being said, I'd like to ask you a question (not sure if it is correct topic, but I couldn't post it on Android development because i am newbie or something...)
I have phone:
e1808_v75_jbl1_5640
Android 4.0.4
Kernel v. 3.0.13
2012/07/27
ARMv7 (at least what that terminal said)
It is rooted (again, thanks to you guys) and I've been messing with it for a while.
I read the post about installing google now on ICS ( ht tp://go o.g l/Lw9mM ) and ran into problem when I was supposed to click "Install zip from SD" in recovery mode. because there wasnt that option. Then i googled some more and found out that i was in 3e recovery, and that I needed to be in Clockwork mode. I downloaded app called "clockwork recovery" and proceeded to enter cwm but apparently my device is not supported. (It also offered to setup it manually, but I had no idea what to do there) and I was not able to do it.
Then I tried GNow Handlebars, but everytime I click any Gnow version, it just returns me back from where I started and nothing happened (Yes it asked for superuser premissions and I gave it)
After that I tried manual installation by using ES File explorer to copy files by myself but I couldnt follow instructions clearly, because I didnt have same version of app, and didn't have same options for superuser. (I downloaded latest ES file explorer)
So yeah, That is my problem, I know buying new phone would solve everything, but I am really satisfied with this one (Not that I have money for new one, but anyways )
P.S. When I rooted my phone, I was able to do so with program made for a HTC mobile, cannot remmeber exactly which one. but if you really need that information, post it below, and i will try to find it.
Update: I used Easyroot ICS program for HTC one S to root it.
Argh! Pulling my hair out over this one. I've been flashing custom ROMs and rooting my phones for years now, since my old HTC G1. Even had KitKat running on my HTC Desire 4G!
... but this Sidekick is proving another matter. I've been through forum after forum, all saying the same things on how to root/flash this thing, but I haven't managed to get anything to work! So, here's step-by-step of what I just did and the result I get every single time, no matter the initial method:
1: Fired up ODIN3.
2: Wiped the user data and cache from the stock recovery (Android System Recovery (3e)).
3: Connect USB cable, reboot phone into download mode (using the battery-pull method).
4: Successfully flash to stock ROM, reboot.
5: Sign in with Google, enable WiFi.
6: Run SuperOneClick, reboot.
7: Grab ES File Explorer from the Market, after it updates.
8: Attempt to replace "recovery" in /system/bin with custom
... and here's where things break. Doesn't matter what version of SuperOneClick I use (and I've tried from 1.9.1 through 2.2.3), nor does it matter what exploit I select. What happens? Well... aside from everything on-screen claiming to be okay, and everything claiming it's working, once the rooting is "successful", I reboot like it says, see that SuperUser is in the applications, it shows me an su binary version...
... but anything that tries to run super-user (ES File Explorer included) that gets added to the super-user list simply does not work. I can't over-write the recovery, can't delete or muddle with anything that requires elevated privileges, and the ROM Manager for sure won't work because I can't get CWR installed.
I love my phones with keyboards. I really do. I'd love to keep this thing, but the stock firmware is driving me up a wall (especially that stupid media scanner). So if anyone has any ideas to throw at me, care to offer some? Haven't a clue at this point what I'm doing wrong.
Hey buddy!
I feel your pain, this is one of the last nicely built hardware keyboard phones, first time rooting it is a bit strange

Awesome! I'll give this a go once I'm all done with today's activities and see if it works.
Well, apparently I have root access for the moment, but it is denying my replacing of /system/bin/recovery - in adb shell, it states "Filesystem is read-only", so I re-mounted /system -rw and no dice. Going to attempt to try again in a moment, after a reboot.
Okay, so since there's a problem with all of this, I'm going to try that second ROM (KD2 I think it was) - but as I recall, it was on a very slow server. Plus I have a load of things to do tomorrow, so it probably won't be until tomorrow evening sometime when I'll be able to flash it. Once I've used Odin to re-flash, I'll get back to you.
Well, I had to dissect "t839-Sidekick4G-UVKG2-One-Click.jar" and remove the xml file from within it, but I acquired the necessary package to upgrade to KG2 from KD1 through Odin3. Took a while to figure out just how to deal with it, and I was successful in flashing... and I even replaced the recovery file after rooting it again!
... however, now it just sits there at the "T Mobile Sidekick 4G" start-up screen when I attempt to boot into recovery, so now I'm preparing to re-flash it again to recover the stock recovery. So... still more on this, later.
EDIT: Also, I named the tar file "KG2OdinHeimdall.tar", since I basically ripped it right off the "HeimdallPackage.tar" file from the Heimdall one-click thing. Turns out, it apparently works just fine if you remove the .xml file from the original tar.
Finally!
I ended up having to use my own method to get the KG2 update installed because the one-click program kept crashing on me when selecting "Show all devices", and I opted to use AntTek Explorer (all you have to do is go into the program's options and it'll attempt to acquire admin privileges, if the device is rooted) to copy the recovery file to /system/bin - but your post worked for everything else, once I got past not being able to copy the recovery file.
I opted for the CM6 package and it's quite fast! Thank you loads, demkantor!
Nice! I'm glad all worked out well for you!
If you get a chance try out the one gingerbread ROM, its cool to see it running but there are still driver issues so keyboard is borked, really makes it pointless to have on this phone...
But there are a few nice froyo ROMs ready to be played with, someday development will hopefully pick up again
Until then, happy flashing!
