Develop Bugs

[Q] Do I really need a computer to get a new ROM?

Whenever I flash a new ROM the instructions always say to download the .zip to a computer then move it to the SD card etc.. Etc.. (You know the drill) Anyway, I've been thinking, you can download .zip files to your phone, so why do i need a computer?
Can't I just download it to my phones SD card, factory reset, wipe cache and then flash it? I really don't see the need for a computer.
Or have I just been naive and haven't heard of any bugs yet? Thanks!

You don't need a computer. You're indeed right to think that. You don't even have to dl it to the root of your sd card because recoveries are file managers anyways.

That saves a bunch of time then. I don't understand why all devs to download to a PC first..

Idk either. Probably because dling to Android from the internet can be buggy.

the most likely reason is that because most roms are 100mb plus in size and the average user likes to test/experiement with various roms and most likely wont delete it from their phone each time, its just smarter in terms of storage to dl to computer but to the sd card is the same ting.

Try flashing the stock recover/firmwares through Odin or RomToolKit. I'm hoping you didn't somehow mess up the partition on the internal.

okay thank you will try it now and report back.

Need help too
I have a very similar issue right now and am able to still access download/recovery mode. I attempted to use the TOOLKIT V3.0.0 for att to restore back to stock. But the problem is it says "waiting for usb debugging to be enabled" which obviously isnt going to happen since it cant boot. Is this still the case with trying to flash back to stock in Odin manually? Please help. I spent practically every penny on this new phone and havent even had it a week...

Set up odin on your computer...go to sammobile.com dl your fw for your phone..extract it to a .tar. .open odin. Press pda put the. File in yhat slot. Make sure only auto reboot and f reset are cheakd...make sure phone is in dl mode flash away

You can always use the advance mode in twrp to copy the file over from external to internal and then flash. Also I'd you have the right drivers installed on your pc you can just connect your phone to computer and copy the ROM over to internal sd. If twrp isn't reading the external do a recovery reboot and try again.

[Q]Backup during Bootloop

So my phone is in a bootloop. I made a dumb mistake, and restarted my phone to be met with a bootloop. My question is - is it possible for me to get my files off of the phone before reinstalling/doing a fresh install? I have access to both download mode and CWM Recovery - I just have some files on here that I really need, and unfortunately, they aren't replaceable. Is there anyway for me to get them off of my phone? I'm running WFTN.
I've tried starting up CWM and backing up to external-sd, but every time I do I get a "can't mount backup path" error. So I go to Mounts and Storage and try mounting my external sd, but I get a "Error Mounting /external_sd!" message. Can anyone help me out?
Edit
Actually, I managed to get the files I needed. I needed some recordings off of the phone, and I was able to plug my phone into my computer via usb (in CWM) and it gave me access to the phone's internal SD card. So I suppose all that's left is actually re-flashing the ROM. I was running an older version of WFTN, I suppose i was due for an upgrade anyway.
However, I suppose my original question remains - is it possible to backup the files on the phone (without using the usb)? Is there a reason I was unable to mount my external sd card?

Just because you are flashing a rom doesnt mean your recordings or anhthing on your sd card is wiped when you flash a new rom. The exception being if you use odin to put a oneclick of a jellybean rom on. Then it wiped internal. And if you are worried about sd card just pull it out. Iirc I was always able to pull files from both internal and external while in recovery using el26 kernel. Not sure where the problem was. But glad to know you got your files.

Unable to Flash ROM, asking for help

Hello all, I recently purchased a new GS4 tmobile variant and have rooted it via Odin. SU shows up in the app section and TWRP installed successfully. My problem is when I attempt to flash a new rom i.e. GE 4.3, I almost immediately get a FAILED message and cant get it installed. I created a backup and have been able to restore so its not been an issue however I really cant figure out where im going wrong. The zip file is on my SD card but no luck... I'm just looking for some direction,
Thanks Andrew

if you installed the rom correctly to the sd card, using twrp, you should be able to do your wipe data factory reset, wipe cash and dalvik, then press install from sd card, choose zip from sd card and install. make sure the rom is on the root of the sd card. when i first started flashing i was having a issue because my device was mounted incorrectly and the rom was not going to the root of my sd card. i started using a card reader that i can mount as a disk drive and send the rom to that. that solved my issues. also i seemed to be having issues with twrp on my device so i started using it and installed clockwork mod touch recovery and things started working then.Also be sure you are trying to install the correct rom for your device variant.i hope this helps some. good luck

The .zip file is in a folder called ROMS i created on the root of the internal memory. Right now im stuck without anything as my backup seems to have failed now as well. I've flashed many roms before and have never run into this so im stumped! I've tried using both CWM and TWRP but both through a "failed" error. I downloaded both the rom package from the Tmo variant GS4 forum so i think they should be right...

I think ive found your issue. You said you placed the roms in a folder, try this, put the rom DIRECTLY on the root of your sd card, NOT in a folder. Give this a try and let me know. I know when flashing with my last device, the rom could not be placed into a folder, it had to be placed directly onto the root of the sd card. So try going back to the computer and mount as disk drive and directly place the rom onto the sd card, then just scroll down to find the rom while in recovery and this SHOULD work. I had a issue mounting as a disk drive so I just used a micro sd card reader and placed my sd card into the card reader, this automatically is recognized as a external disk drive and I'm able to place rom directly to root of sd card this way. When I tried hooking up my device directly to the computer it mounted as a media device and would not allow the rom to be placed correctly on the root. So that's how I got around that. So keeping these issues in mind, try again and place the rom directly to the sd and NOT in a folder and see if your able to successfully flash after that. After I did these things I was able to flash without any problems. Luke I said when I first flashed these were some issues I encountered that was prohibiting me from flashing correctly. Now I don't have any problems flashing. Please let me know if this works out and enables you to successfully flash. Hope this helps

[Q] no OS and ROM zip files corrupted on external SD!

While on the below thread .. I eventually ended up making my TWRP to format my data, system, cache, as well as internal storage!
http://forum.xda-developers.com/showpost.php?p=46522379&postcount=364
Now it is all gone. successfully.
Note, when i formatted the internal storage - it did ask me to restart to update the partition tables. I did that. I warned me that there is no OS. I went ahead and restarted in recovery. I could browse using TWRP->advanced->file manager and see the zips on external sd card.
I had gapps and rom zip files copied on external SD card. When I try to flash those in TWRP, it throws an error - E: unable to open zip file!
Now I can not flash any of those! there is no OS also on the phone! I suspect that the external SD card is corrupt! I have good zip files on my computer (it has no working sd card reader).
Is there any way, i can transfer these zip files from my computer to phone's internal storage from where i can flash them?
please help!

There's no way to effectively access internal SD without having been mounted first.
But there are two ways you can do this.
1. Take the MicroSD Card and insert into the PC via Card Readers.Then copy the zip files there. Properly eject the card from PC then insert it into the phone. Now TWRP will recognize the files and flash them. If it still does not then its a bad download so download again. Also while there, get the MD5 values as well for your zip files. This allows the recovery to validate the files. If you still have errors then roll back TWRP to version 2.5.0.0
2. Put phone in download mode. Use Odin on PC to flash one of the rooted stock roms. After that, proceed to re-download on phone and try again.
P.S. - I typically never let Recovery to format my external card. Then the file system issues start popping up.
EDIT - I noticed from your other post that your PC does not have a working SD Card Slot. In that case, you could put the card in another phone and then copy the files to this sd card and then use that way.

How do I flash CM or MIUI ROM using odin? I am trying to search the forums but unable to find anything! odin needs a tar file and all these roms come with zip file! What do I do?

You can't unless the dev specifically made an Odin flashable version, which they never do. Flash the stock root66 firmware with odin.
You can't access the internal storage simply because it's not there anymore. When you chose to format data, it completely wiped out the /data partition. Your internal sd is really located at /data/media, but until you can reboot, this won't be recreated.
I doubt the external sd is corrupt or you would've seen issues before your wiping frenzy. But you can use adb while in recovery to connect the phone to your computer. Search for adb sdk install guide, or similar.
Best option now is to try Odin flashing the root66 firmware.
Oh, and you probably know by now, but never format system! This should only be a last resort type thing imo. Never understood why people recommend it for things like prepping for a Rom flash. The Rom will format system during install anyway.

I used this
http://apcmag.com/how-to-unroot-your-galaxy-s3-and-flash-it-back-to-stock-rom.htm
and got the stock rom back. appeared like that was the only way to get back to running system. Now it's alright.
to my surprise, following problems disappeared.
1. The SD card no more automatically ejects!
2. battery lasts longer!
3. no random reboots at all!
never thought .. i would feel good getting back to stock rom !

Isn't that exactly what we were telling you to do in the first place though? Use odin to flash stock/root66 firmware? I think you just took the long way is all. I also have all that firmware hosted so people could download it much faster than by using sammobile or samsung-updates hotfile downloads.
Either way though, glad you got it running again!
Just posting so others know if they come across this in the future.

yes guru! you said it.
I tried adb route too ... but for some reason it never detected my device. I tried removing, installing drivers, getting sdk and all. then tried the odin route.
Now will stay with this rom for some days ... before I get back to MIUI ... want to see it working ... for some reason it was continuously making my phone reboot! now that it is a clean slate, i hope this time, it will work!
fingers crossed!

If you want to try adb again for anything in the future, there's a different driver pkg that would probably help there. Adb universal drivers. Theyre in my driver repo with the rest if you ever need them.
