[Q] Artemis without ROM - P3300, MDA Compact III General

My P3300 is without a rom. I had problems previously and had to install the original rom via bootloader mode. It worked for a while then began to freeze and automatically restart at times. tried to upgrade the rom to a different version but was not successful. it gave me the restore mode but was also not successful. Now my phone is without a rom and i cannot install any rom to it as well. it gives me Invalid vendor id error or corrupt image for all the previous working roms i tried. it begins the update then the phone reboots at 2%. need help desperately.

You can try to flash your device with the SD_Card Flash method look for it here:
http://forum.xda-developers.com/wiki/index.php?title=Artemis_SD_Card_Flashing
1. Download the original rom for your device that was installed at the beginnig you bought the device with.
2. Extract all the contents of the installer file (winrar or a similar prog.)
3. navigate to the extracted original rom (RUU_signed.nbh)
4. Rename the file to ARTEIMG.nbh and put it in the root of your storage card
5. put the card back in to your device and hold down the voice button after you press the power button.
6. Now your bootloader should show up and check for the ARTEIMG.nbh on your storage card.
7. Slide down the volume button and it should begin to flash your device.
8. After flashing process is finished. Power device off and do a hard reset.
If your device is working again and you need further help for unlocking your device (Super-CID) to flash custom roms pm me or post in this topic.

[Q] Cannot flash other ROMs after installing CM 7.2

HI,
Ever since installing CM 7.2 I cannot flash any other roms, I get constant HTC screen or staying on Android logo. I am not new to flashing custom roms .
I have done all wipes before an installation and after to see if that makes any difference (sadly not) The only rom that works is CM 7.2!
Anyone got any ideas what to do
thanx pp
Try removing Battery and then again switch on the phone
then same
vol dwn + power
recovery
then flash new rom
Try installing an official ruu then after that try another custom rom.
still no joy ! unrooted back to stock then rerooted and still the same
Perhaps you need a GoldCard to install a ruu official ROM.
seems my device cannot handle OC roms! any ideas why??
I had the same problem, and even CM7 stopped working....don't think my phone likes overclocking either, even if i install the overclocking kernel on stock rom, the phone goes mad!
to get back to stock:-
-if you are able to get to CWM recovery, go to that first and clear all cashes, format all drives, just basically choose EVERY "clean", "clear" and "format" option to wipe everything from the phone.
-use the same directory you used for the htcdev unlock (usually c:\android)
-search this forum for a thread called "s-on gsm how to upgrade to 2.3.5" or something like that, and download the file "Gingerbread 2.3.5 (v2.13.401.2).zip".
-extract this file and find within it "rom.zip"
-extract rom.zip to the same folder you're using (e.g. c:\android)
-you should now have files called C:\android\boot.img, c:\android\recovery.img, and c:android\system.img.
-open up a command prompt window and navigate to c:\android\
-turn your phone on while holding down the -vol key to get to hboot menu
-choose "fastboot"
-connect your phone to your pc via usb, you should see it say on your phone screen "FASTBOOT USB" or something like that, in red letters.
-now, on your pc, use the following commands to flash everything back to stock
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
after this is done (usually only a few minutes), exit the command prompt, power off the phone and restart.
you should now have a fully restored back to stock and working ROM (although you will have to set up all your contacts, all your home srceens, options, settings, and re-download all your apps etc.
-if it's confirmed working, i reccommend then IMMEDIATELY installing CWM recovery, and making a full backup, then next time things go drastically wrong, you should be able to wipe everything then just install this backup (remember to store the backup on your pc, don't just keep it on your mem card).
good luck, this method worked for me, so hopefully you will at least get a working phone again, and if you then want to try other custom roms, you can....but i think some phones are more picky when it comes to overclocking.....i can't run anything that overclocks without the phone freezing/crashing/needing battery pull and reset.
thanks. i will give it a try

[Recovery][CWM] CWM 6.0.2.8 for Mach Speed Trio Pro 9.7

So, there is actually a WORKING CWM 6.0.28 recovery, with an installer that runs from a root shell.
All features work for me. I'm able to mount my internal SD as USB, do a CWM backup, navigate through menus, etc
I didn't create it, but since it is verified working on this tablet, and I had such a difficult time finding a working CWM for this device, I thought I'd post the link and which file to grab.
Thread: CWM 6.0.2.8 for Allwinner A10 & A13 Tablets - v2a
http://forum.xda-developers.com/showthread.php?t=2189640
Download the file:
cwm6028-a10-10part-v2.zip
This is a 10 partition AllWinner A10 device, so that's the zip file we want.
NOTE: This "guide" assumes you know how to copy files via ADB, use basic Linux commands, and
Manual Install Method (Known Working):
Extract the files, copy the two .sh files and the recovery.img file to the device using ADB (probably /data/local would be a good spot). Make the .sh files executable (chmod 777 *.sh), and run install-recovery.sh
It will install the recovery for you. Takes about 10 seconds or so.
The reboot-recovery.sh script reboots to recovery. Go figure This device has an interesting way of rebooting. Check out the guts of the script for the command if you're interested. BTW, don't use any 3rd party utilities that reboot the system. It will probably end up in a factory reset of your device. I did that by accident... more than once.
Automatic Install Method (Might Work, Worth A Shot):
I'm not sure if the stock recovery will flash the ZIP file, but I would give it a shot before trying the above method. If it does let you install it, then it's a MUCH quicker way
Other Information:
Boot to recovery manually by powering the device off (holding the power button for 10 seconds). Then holding Volume Down & Power until it powers on, then release the Power button while still pressing the Volume Down button until the recovery boots.
Sorry for the scattered post. I'm just happy to have a working CWM and wanted to share it.
I can confirm that the stock recovery is able to install cwm6028-a10-10part-v2.zip from external memory. Quick & painless.:good:

[Q] cant install root file from internal storage?

Hey guys im trying to root my device so i can install some lightweight custom roms. Ive been following this guide i found online
http://androidcritics.com/how-to-root-and-install-clockworkmod-recovery-on-galaxy-s3-i747/
I basically did this
Installing Clockwork Recovery Mod
Find the recovery image file which is clockworkmod.tar
On your Samsung Galaxy S3 I747, press and hold down the volume down, power, and home buttons
Once your at the warning screen, press volume up to accept
Launch the Odin program from your computer
In Odin, find the PDA tab and click it
Find the clockworkmod.tar.md5 file in the unzipped recovery image file
Press start to begin flashing the recovery mod
BE PATIENT! and wait until your device reboots
Once your device has fully rebooted, you can start installing root
It loaded on the phone fine. I then did this
Installing Root
Transfer the root.zip file onto your phone from your computer
Make sure you connect your s3 to your computer and find the root zip file and put it in your downloads folder.
Enter clockwork recover mod by holding down the volume up, power, and home buttons
Navigate by using the volume buttons to Install Zip > Choose Zip from Internal SD card > Navigate to the downloads folder> Select
Be Patient! and wait until your device is finished
Once the process is finished, you can select Reboot
Once your device has rebooted, launch the Google Play Store app
Search “SuperuserSU” and select the first app that shows in the search results
Install this app
Once it has finished installing, your done!
The only problem is I cant navigate to the option "install zip from internal sd card" I simply dont have though's options here is what I have when hold volume up reset and home
"reboot system now
apply update from ADB
apply update from external storage (which i dont have)
wipe data/factory reset
wipe cache partition
apply update from cache
When i hit apply update from ADB it says "now send the package you want to apply to the device with "adb sideload <filename>"...
Im wondering if the original flash didnt go thru? Why dont I have the options that I should?
Any help would mean the world trying to get this puppy up asap!

Sounds like the root method you are using is just way to complicated. Follow this one here http://forum.xda-developers.com/showthread.php?t=1739426 it has prerooted firmwares that you just install with odin and you are done (cwm included). Just make sure you grab the right firmware for your carrier.

Beauty I think its flashing the rogers rom to my phone from there Im good to load other roms using this odin tool? (or is it rom manager?)
also what is this clockwork mod ? I might as well go into play store and get both rom manager and clockwork?
- eddy
So After I flashed the new rom to my phone i left it plugged in and it restarted. Android loader popped on and now it says android is upgrading... starting apps. Its been like this for over a half an hour... what do i do??? helpppp dont really want to reset it but it is bricked? or do i have to reload ?
update:
held the restart button down it restarted bit is still stuck on starting apps.
update two:
held vol down home and reset tried to reload the rogers rom onto the phone and now it stops at samsung load screen. Do i have to reload the carrier that came with the phone? I cant quite remember what the original carrier was.
UPDATE THREE:
I as able to boot back into the phone but...nothing changed? i ended up wiping the phones data in settings because its too full as it is. I downloaded root checker and it said access was denied ? That makes its not rooted after all... I followed the directions seems that they didnt take? Any clues?

Okay buddy looks like you need to learn some basic android 101
You are definitely not ready to root or do anything til you learn this stuff...
Okay, so first is recoveries. Basically recoveries are a bit of software that let's you flash ROMs, kernels, and whatever else to your phone. When you hold volume up and power when your phone is off, you boot to recovery. Now basically recoveries are necessary because when you are flashing a new ROM it essentially deletes the android system from your phone first so this is a way of your phone still working between flashes.
Clockworkmod is a custom recovery with a lot of features meant for flashing ROMs. There are competitors such as TWRP (team win recovery project) but clockworkmod is a great starter. Use videos or tutorials on how to use it before you flash your first ROM. I can not stress how often you need to read read and read some more.
Okay so rooting your phone. Basically there is a "root" directory of your phone. Its where all the system files are stored and it let's you do a lot of stuff, but it also means you can screw a lot of stuff up to (like really screw it up). On default you are locked out of here by the maker of your phone for various reasons. Rooting means that someone found an exploit to gain access to this folder. Usually what you then do is you find a way to inject superuser (a little app that gives root access to other apps later on). You use Odin in this case to install a stock Samsung rom (with superuser already put in the root directory of that modified ROM its installing) essentially this means you have root. Root allows you to install recoveries like clockworkmod (which you need to flash ROMs later.
Okay so that was my quick run through. At your point you need to go to YouTube and Google how to root the sgs3 and hopefully they should have one for your specific carrier. The process should be the same minus the files you flash. Essentially you should be looking for stock ROM (for your specific device) with superuser or supersu already installed. Then you should be finding a way to install clockworkmod once you have root. (You may be able to find a file or tutorial that does this in one go). I cannot emphasise enough about reading. You wouldn't be here had you read first and in the flashing business, if you don't want a sgs3 paper weight you should read first.
Oh and ROMmanager from the marketplace installs clockworkmod for you (ONCE YOU HAVE ROOT) its simple. Just download it from the play story. Click flash recovery. It will load a bit and your done. Then you can reboot into it. ROM manager (the paid version is unnecessary) it just adds extra features you don't yet need. Look at it once you have flashed your first few ROMs.
Best of luck. Let me know and slap that thanks button. I wrote this on my phone.

Hi eddy,
It sounds like you didn't get CWM to stick after your flash with ODIN. You need to uncheck the reboot option in odin and then after the flash is done pull the battery and go directly into CWM loader by booting with the volume up + power + home button method. This will give you cwm rather than the stock loader you seem to be trying to use. You're almost there!

I think he can't install the superuser.zip from cwm after boot because he's allowing the stock rom to overwrite his cwm flash ... he's gotta pull his battery after the odin flash to get root in. That's what worked for me. once he's got root he can use rom manager to upgrade to cwm 6.x

He shouldn't need cwm to install. If flashes a firmware with root already injected he can then just use rom manager to install clockworkmod for the first time since rom manager just needs root which he will have. You can root and keep the stock recovery on at the same time
I think his biggest issue is root not sticking. Til he does that cwm wont install

[Q] Problems with android update

Hello guys, i'm from Poland so sorry for my language. And this is the main reason of my problem. Because I've the Samsung galaxy s3 from AT&T . And my android version is 4.1.1. I want to go 4,3 but I can't because I need to be connected to AT&T network and for now I don't have that option . I've tried to use Samsung kies but it says that i've the newest version.. So how can i upgrade my version to 4.3 ? Is this even posibble ?

That's fairly simple. There are a variety of options for you to manually update to 4.3. First you can try downloading Samsung Kies 3 to your PC. Kies 3 is an enhanced version of Kies and is for system on Android 4.3 and up. If this doesn't work, then you may take the following steps:
1. Download the 4.3 stock ROM from the link below. If you would prefer to install the rooted and knox-free modified version of the ROM, you will find the link on the right side of the page. Otherwise, the official stock image is the file named AT&T_I747UCUEMJB.zip
http://www.androidfilehost.com/?w=files&flid=438
2. Download the 4.3 stock kernel and modem zip files as well.
3. Copy the downloaded files from your computer to the internal SD card of your phone or to an external Micro SDHC card and place in your phone.
Power off your phone and boot into recovery mode by holding down the Power, Menu and Volume Up buttons simultaneously. When you see something flash across your screen, release the power button but continue to hold down the Menu and Volume Up buttons until recovery mode comes up (you may check You tube for videos of how to boot into recovery).
3. Install (flash) the downloaded files from wherever you stored them and wait for flashing to complete.
4. Wipe and reset your phone and you should be OK.

Then I downloaded the files and put them on external card without unpacking . And when I try to install it says.

No, there is nothing wrong with your phone. It would appear you are on stock recovery. It should be possible to flash a stock zip from stock recovery but sometimes it doesn't work and you may need custom recovery which has more enhanced features and functionality. Let's try doing it via custom recovery as follows ..
Download the Odin 3 v1.85 which is attached as a zip file.
Download the flashable TWRP file via the following link and save to a recognizable location on your computer ...
http://techerrata.com/file/twrp2/d2att/openrecovery-twrp-2.6.3.0-d2att.tar
Extract the Odin zip and run the executable file (*.exe). Make sure Odin opens.
Power off your phone and boot into download mode. Same process as you did with recovery mode except that this time, you'll be pressing Power, Volume Down and Home buttons. When you get to the warning message, press volume up to continue.
Connect your phone to the computer with a good quality USB cable. Since you have Kies, you probably have the required drivers for the phone to run on your PC. Make sure Kies is not open or running, however, not even in the background as Kies will conflict with Odin if both of them are open.
Go to the Odin window. Make sure it has recognized your phone. You will see 'Added" in the left pane as confirmation.
Click on the PDA button in Odin and navigate to the TWRP file you downloaded earlier. Select this file. Make sure it has registered in the PDA tab and then click Start. This will begin flashing TWRP custom recovery to your phone
Leave the Odin settings unaltered. The Auto-Reboot box, for instance, should be checked. Do not check or uncheck any boxes
Wait for the flashing to be complete and until you get the PASS message. Your phone will power off then and begin rebooting. The process is complete and you can now disconnect the phone from the computer
Power off the phone and reboot into recovery mode. You should now see TWRP recovery. Click on install and retry the process you tried earlier with the zip card. Hopefully, it will work this time. If not, we would try the ultimate solution which would be to download the complete 4.3 stock recovery image and flash via the same custom recovery.
When the installation is complete, please wipe your dalvik cache and do a hard wipe/reset then reboot into system
Ok so I did everything what you wrote. My phone reboot and now I have android 4.3 thanks!! But i couldn't turn on the wifi so i cleaned the cache againg and reboot the system and it's stuck on at&t sign and i can't do nothing. Did I broke my phone? HEEELP!

Don't worry. It's a minor problem. Try booting into recovery mode again and do a hard wipe/reset from there. Once it reboots, you will need to establish your Wi-Fi during the initial set-up
If you experience any further issues however, now that you have custom recovery, you may want to try the ultimate solution which is to flash the complete stock recovery image for 4.3. This will return your phone to full stock 4.3, reset your flash counter and also return your phone to stock recovery. In short, your phone will behave like a new 4.3 from the factory. Please see the file posted in the link below which you may download and flash via TWRP. So far, there have been no reports of failure with flashing this zip but please proceed at your own risk.

No I mean that when I press the "off" button on wi-fi it should automaticaly switch to "on" but it keep coming to "off" . I was reading somewhere that somebody had the same problem but I don't remember where. Oh and samsung kies saved my and helped me to came back to android 4.1.1 and I did the same thing and for now it's working on 4.3 but I still have problem with wi-fi. Ok I found the problem . I have wrong modem thats why I can't turn on wifi , but I can't find the right one.
Edit; I found out that when I install some thing it says
checking MD5 file
Skipping MD5 check: no Md5 file found.
Do you think that's the reason of the wifi problem

Edit; I found out that when I install some thing it says
checking MD5 file
Skipping MD5 check: no Md5 file found.
Do you think that's the reason of the wifi problem

That's unlikely to be the cause of the Wi-Fi problem. Custom recovery makes that check when you are trying to flash a zip. Can you check what modem you have? You will see this written as baseband version under Settings => About Device

The Plan (now guide)

The post below started out as my proposed plan for updating a S3 i747m (Canadian) from stock 4.4.2 to CM11. I've since gone back and updated it with the results to turn it into more of a guide for the next moder. This will not do a carrier unlock and it will flip your warranty bit.
Prep:
Download and install Odin_v3.09.zip (recommended for JellyBean/KitKat firmwares) (droidviews.com/download-odin-tool-for-samsung-galaxy-devices-all-versions/)
Download and install the Samsung drivers (samsung.com/us/support/owners/product/SGH-I747MBBATT#)
Download the latest appropriate TWRP (at the time if writing it was twrp-3.0.2-0-d2can.img.tar, not the .img but the .tar file, from the dl.twrp.me/d2can page).
Download CyanogenMod and copy it to the external SD card (started with the latest CM11 build with the stagefright fix from download.cyanogenmod.org/?type=snapshot&device=d2lte).
Download Gapps and copy it to the external SD card (personally I grabbed the ARM/4.4/Nano from opengapps.org).
Install recovery:
Boot into Download Mode on the S3 (hold home + volume down, hit power button, then volume up at the confirmation screen)
Launch Odin (as admin) and uncheck everything except Auto Reboot and F. Reset Time.
Select the TWRP .tar file in the AP (apparently used to be PDA) mode and flash the recovery
Once the phone has rebooted successfully, shut it down.
Install CyanogenMod:
Boot into recovery (hold home + volume up, hit power button)
Do a nandroid backup for good measure
Do an advanced wipe of your system, data, internal storage and caches (if you don't you get an error 7)
Flash CyanogenMod
Flash Gapps
Reboot
That successfully installed CM11. As it went so smoothly, I decided to try install CM12.1 right away. I grabbed the "cm-12.1-20160314-NIGHTLY-d2att.zip" (from here: forum.xda-developers.com/showpost.php?p=66726324&postcount=1202), got a copy of the ARM/5.1/Nano from opengapps.org and repeated the above process with success. All seems to be stable so far.
One unknown I had was the deleting of "/system/etc/install-recovery.sh" and "/system/recovery-from-boot.p" as specified in some guides. audit13 mentioned it probably wasn't necessary and I can confirm it wasn't.
Thanks again to audit13 for their vote of confidence.
Plan looks good except I don't think it is necessary to mount the partition in twrp and delete the two files. I have flashed the Telus and T-Mobile versions of the s3 with custom roms and have never had to delete any particular files prior to flashing.
