What's wrong with my phone

Ok I'm really irritated right about now. I am unable to flash any custom ROMS on my phone. Actually let me rephrase, I can flash them but many things do not work. I have tried Wicked, FreeGS3 and CapROM. They all have the same issues. Let me explain.
Once the ROM is booted I get odd string of numbers and TXT in the status bar, (goes away, think nothing of it)
Root not avail/accessible by root apps.
Home button does not work
Play store missing
standard Google login prompt at first boot is missing, it never asks me to login
Using CWM 5.8.4.5 Touch Recovery
TMO GS3 Rooted with Odin no trip method
I don't get it. I am i just stuck using stock ROM? If anyone can help I would love you forever.

are you clearing /cache and dalvik-cache before you reboot to the custom rom?

If you mean clearing those after the install (in recovery completes) then no. Basically after the install I just reboot. Obviously clear and reset everything before I install though.

Really? A recovery can cause these kinds of issues. Haven't heard of that before. Any other thoughts? What recovery are you using?

Try TWRP 2.2.1.1

Yeah I've heard touch recovery has its problems so I don't use it. Try using the recovery rom manager gives you.

I use TWRP and have no problems.
Do a Factory reset, wipe cache, wipe dalvik cache, fix permissions.
If that doesn't work, flash stock and reroot and try again.

I use touch recovery 5.8.4.7 and flashed it with adb. I've flashed almost everything. Cyanogenmod and every other ROM. NEVER had a problem with an instalation. Or even lost IMEI. I think people specifically aren't reading over OP's and figuring out what's safest for their devices and end up with these kind of results. Just my input.

Use mskips tool for our phones. It does everything you can image and then some. I have been using his tools since the HD2 and no issues to date.

The odd string of numbers that flashes upon boot in the status bar sounds like it's just identifying your external sd card. Totally normal.

OK so nothing worked. TWRP did the same thing. Tried diff ROM, same thing. I flashed back to 100% stock, unrooted ROM. Wiped the phone in the standard Android recovery. Then I rooted again, installed TWRP and flashed my ROM of choice and voila. Everything works. Problem solved. Thanks all for the inputs.

[SOLVED] [Q] HELP!!! Bricked My Baby!

I was playing with Rom Toolbox Pro and was changing the status bar icons. I did agree to the backup requests. In the middle of one of the icon changes, the program glitched. I tried to give it time, but it would glitch again. I finally removed the battery and now it won't go past "Samsung". Since I am on Ting an MVNO of Sprint, I don't have Sprint's boot animation, pure Samsung.
I did hold the volume / power / home buttons and tried every choice but factory reset. Though there is a high probability being new and stupid, that I di them wrong.
So . . . HELP!!!

When you get to to recovery restore a backup if you made one. Which you should always make a backup before making changes on ur rom. Or you may have to reflash the rom. If you can get into recovery your phone is not bricked.

I can get into recovery, so the term is soft-bricked I believe. I didn't think I was doing a ROM change, but again I am new and stupid.
I did not do a backup, but Rom Toolbox Pro did for the files that changed. I cannot find those backup files in the in recovery. I went through every folder in "Apply Update From External Storage"

If you can find it i guess your only option left is to wipe everything and flash the rom again so you can get your phone to boot.

Contacts should be all synced to gmail. Just reflash and wait a minute for them to come back all by themselves after you log in.
I don't remember if the latest twrp has a file manager function (can't check while using the same phone to write thisn post) but if it does you might be able to replace the files that way. Otherwise, one theoretical option is you could extract the files from a stock rom and make a flashable zip that just puts those exact files back, copy the zip to a microsd card using a card reader & a pc (i don't think you can do much via usb while in recovery). Pop sd card back in phone and flash with twrp.
Possibly less work to restore contacts by hand again. This time let it sync to gmail so you won't be so screwed again. Better yet use titanium backup or rerware mybackup so you get txts, call logs, bookmarks, wifi keys, bluetooth pairings, contacts and apps.

I try to avoid google spyware as much as possible. (I know, I know, I chose Android)
I did install Titanium Backup Pro, but never did a backup. :crying:
I was already and waiting for the download to finish of the Sprint ROM to put it on my MicroSD. Didn't think about just replacing the bad files and was just going to flash it again. I don't know if I am knowledgeable enough to pull off just replacing a few files. I may end up learning the hard way.

Unfortunatetly the "factory reset" option in TWRP is not the most descriptive wording.
All factory reset does is delete the data partition. It doesn't restore the OS userspace programs or the kernel or the modem/firmware or the bootloader.
Now that you've done that, there is no more chance to recover anything, which means there is no more reason to agonize over reflashing a new rom. Go ahead and flash away.
Simplest way, since you have a working custom recovery, is use a pc to download one of the recovery-flashable rom zips and put it on a microsd card. Put the sdcard back in the phone, boot into recovery and flash that zip.
It's simpler and safer than trying to use odin.

Thanks, I wish I knew this before though. Hard lesson #1.
I've done a search and can't find any unmodified "recovery-flashable rom zip" Then I wouldn't know what to do with it. Desperate - how much to fix this? I am in Westchester NY.

Did you only factory reset and reboot?
You should just factory reset, wipe cache, wipe dalvik cache and reflash your old rom, then reboot.

I hope the experience doesn't scare you off flashing forever. You're actually not in bad shape right now. Your recovery is doing it's exact job it's named for. Your phone is booting into recovery, and twrp in particular is a powerful flexible one. It's a whole mini OS really.
And even if your recovery was screwed too, you could still use " download mode" and odin to flash everything back, it's just les convenient and less well documented but the standard recipe of steps is up there on galaxynote2root.com and elsewhere.
There's also a one click back to stock here on xda too. That runs from a pc and attempts to do everything to go all the way back to factory, including firmwares, bootloader, even resetting the flash counter back to 0.
Really your problem is that there are so many options it's confusing to figure out how to choose which one!
Hang in there. Try flahing the zips I pointed too and if there's a problem don't worry just post back here what happened.
For intance, when I flashed those, I had to an extra reboot that the instructions didn't say. After I flashed the firmware zip, the rom zip wouldn't flash. It just said failed in red letters. Scary. But I rbooted back into twrp and it flashed fine then. That happened a few different times on different roms after doing manual wipes in twrp also not just after flashing firmwares.
So don't worry.

I followed to the letter the MA5 installation from Stock_Rooted_Deodexed _Ma5_Rom and LJC-MA5 firmwarezip Links UP!
It didn't work, even after rebooting twice via recovery. So I wiped cache and user data again and rebooted. My baby is till stuck at "Samsung" in the boot animation. :crying:
KEYofR - This is so depressing and I really do appreciate your encouraging words right now. I wish there was a Super Thanks button.

Sorry didn't read ahead. If you are on TWRP recovery just grab any rom and flash it and you should be booting. Make sure after you flash not to wipe anything (especially system).

bhint15 said:
First question and if you can't answer this then you need to read up on ODIN and reflash back to stock. What recovery do you have installed? How did you perform your wipe that isn't allowing you to boot? You mentioned you wiped everything else so if you wiped system/etc then yes your phone will not boot.

I agree, I need to read more. I am learning every day. There is just no handbook that I can start on page one and start reading. So my limited knowledge is scattered. If flashing back to stock will fix it, then so be it. If you have any suggestions on what to do next or what to read, please tell me.
Oh, all the wipes I did was from the recovery menu. I don't think system was one of the choices. But it didn't boot before I did that either.
EDIT: Looking at the recovery menu, the only choices are
*Wipe data/Factory reset
*Wipe cache partition
So no system wipe choice there.

Re: [Q] HELP!!! Bricked My Baby!
You may have to use ODIN to flash back to stock. First thing I would do is see if the phone will get into download mode. It's volume up or down with power button and home button.
If you can get into download mode you will have to use ODIN on your PC to get back to a stock rom. Thats my advice at least.

Re: [Q] HELP!!! Bricked My Baby!
After flashing ma5 and rebooting, did you let it sit on the samsung screen a while? I forget what the circumstances are but sometimes it can take a minute or so on the first boot.
You could try this one.

What methods have you tried?
adb reboot recovery is the easiest way to get to recovery
Maybe try flashing CWM, seeing if that works, and then flashing TWRP (I've never flashed TWRP through Goo Manager so I don't know how that works)?
If you don't have adb set up, get quick boot from market and try recovery through that.
If that doesn't work, I honestly don't know. I'm assuming you've done the power off then volume up+home+power at the same time trick already.

I would highly recommend putting TWRP back on there. The CWM was more for testing... people have reported issues using CWM with certain ROMs. Glad you were able to get CWM on though.

Nothing wrong with CWM.

There are a number of ROMs that do not support CWM so that statement is false. FreeGS3 loses update functionality, for example.
Also, there have been complaints in the case of CWM touch of it being too easy to wipe your entire device.
Not to mention there is no Goo Manager functionality without TWRP as well.
Lots of benefits of TWRP versus CWM. I used CWM for years then had to switch to a modified TWRP for my MAXX and was more than happy when I found out the SGS3 used TWRP as well (although I wish we had the ROM slots like the MAXX though - that was actually cool)

The statement is not false. I think FreeGS3 hasn't been updated for 4.5 months? Maybe not the best example. And I still think you should use as few automated tools as possible where flashing is concerned (Goo/ROM Manager).
It can be easy to wipe the wrong partition in CWM, if you are careless or illiterate. In the 6 months that I've used it (nearly every day), I have never once wiped the wrong partition, or my entire device. Never had a backup that wouldn't restore.
I like some of what TWRP offers. But I still experience showstopping bugs with it on my device. At this time, the devs are unable to track down the cause of the problems.

Don't get me wrong, I've used CWM on many devices for years and even have a premium license for ROM Manager but I've seen a number of ROMs explicitly say not to use CWM, FreeGS3 was just the first that came to mind. I don't flash often because quite frankly, I have no problems with Wicked v8 and see no reason to switch to anything else.
And I am neither careless nor illiterate but I have accidentally borked things using CWM before in the past (it was a modified CWM Touch recovery) and I was not happy.
I think most of the complaints about CWM these days though come from CWM Touch, not regular CWM. Sorry TWRP has issues for you.

OK, so I'm getting a new issue, I changed to AOKP and I had problems with the ROM saying I needed to wipe data, I did, the issue persisted for few reboots, now apps won't install, and for some reason the /data folder still displays apps from my previous ROM ugh I don't know what's happening

Which recovery? Try erasing data, cache, and system three times each and reinstalling the ROM... If that doesn't work you might consider doing a back up of everything internally stored on your phone and then wiping the internal storage entirely and starting over.

[Q] N7 bootlooping on custom rom?

Okay, so I bought the n7 v2, went home, unlocked the boot loader, and rooted it. I've tried to flash versions of vanir I built my self, the betas that are posted here on the forums, and I also tried carbon ROM. Every time I flash a ROM, my device bootloops, so I just hold power + vol down to get to boot loader mode so I can boot into recovery. Any fix for this? I've tried flashing a stock IMG and re rooting to. No luck.

Did you boot into the tablet after unlocking the bootloader but before rooting it? If not, try formatting data (not factory resetting) in recovery. I had the same experience and my sdcard never got populated with the default folders and files, remaining at 0MB. Apparently, symptoms of this problem include being unable to factory reset from recovery, being stuck on the splash screen, and having TWRP demand a password.

I'll try that, maybe its because I restore my data after I wipe it that this happens. Another thing I've found is that after I flash and the restore my system partition that I backed up, su says that no subject binary was found, even though I've flashed it a million times. And some root apps don't work because it says no binary is found.

Phone is rooted now I need help with installing cyanogen mod.

Good day everyone.
I have successfully rooted my S3 1747.
I have done a backup after installing Rom manager. I also have a nandroid and titanium backup completed.

Am I able to get my stuff back after the install?
Thanks in advance

Most system app data will not be compatible. I don't know about CM, but in TW there's an option to export contacts to SD. It'll save them in a .CSV file. Maybe you can import them to CM contacts like this. Might want to confirm that first though.

Thanks for the reply. I'm going to do this later. Does cyanogen live up to the hype?

Everyone has their own preference. I personally like touchwiz better. There are plenty who would agree and disagree.
If you've got a nandroid backup of your current set up, its pretty easy to flash a bunch of different ones to see what you like, and then go back if none keep your interest.

When you say cm installer. I assumes you are talking about the app and pc program that does everything automatically. It says my phone is compatible however wouldn't work originally. I had to root and use twrp. Can I use that to update from now on or should I continue to use twrp?

Well for me cwm is the easiest to use as you just wipe and flash.....its purely up to you, if your gunna use twrp just download the zip boot recovery wipe system, cache, dalvik cache, data (factory reset), and hit install zip and bam you got cyanogen

I wouldn't wipe /system before a flash. If the rom fails to flash youll have no OS to boot into, and it can be a huge pain to get it back. If the rom does flash, its first step will be to format /system, so it gets done anyway.
I think this may be one of those things people used to have to do on some older devices, and was carried on to newer ones. I just think its an unneeded extra step, and more than a few times ended up taking a day or two to help people get their device working right again.

Yeah, its extremely common advice. I see it all the time. There are rare times when it is necessary to format system, but I dont feel a rom flash is one of them.
Its still possible to end up with no OS after a failed flash, but the chances are greatly decreased by eliminating that one step!
