Should this be cause for concern? Long term effect, if any? - T-Mobile Samsung Galaxy S II SGH-T989

I have flashed lots of roms on my friends, relatives and customers T989 (must be close to 20 S2s). Each time, I always followed the developer's direction to the T, i.e., checked, verified MD5, wiped clean and flashed clean, let sit for 12 mins, reboot, and sit for 5 mins, reboot and set up.
So on this particular might, I encountered a rare occurrence that gkt me startled. While reboot from fix permissions in twrp, I noticed that the SD card symbol wouldn't disappear from the notification toggle.
I went into ESFile Explorer, and it said that the "SDCard or USB Storage not properly mounted." So, I pressed the power button for 10 seconds then it reboot but got stuck at the SII International boot animation logo. Had to do battery pull, boot to TWRP, wiped cache/dalvich and fixed permission. After that, it booted normally.
My main concern, or question rather, is tje internal sd/usb storage at risk of "crashing"? Any outlook that anyone can provide would be appreciated.

Sounds like a normal everyday problem after just flashing a new rom to me, pm a dev if you're worried they're awesome people and quick to respond, and know more about this phone than any random who's going to see this thread probably

You don't need to fix permissions after flashing.. and if you're going to don't do before even booting the ROM for the first time. God I can't believe people still can't flash properly.

[Q] Gio won't start without being connected to the charger

Hi,
I've the following problem with my Gio. First, it didn't want to start. When I plugged it the charger, a symbol of the battery appeared on the screen with a yellow triangle, indicating that the temperature is too cold. And it wasn't cold. But I could start up the phone...until I removed the charger. My phone fell out directly.
I had a rooted version of the original firmware, so I tried to connect my phone to Kies. Didn't work. So I flashed a clean rom, 2.3.5 with Odin. My phone is working again, but I still have to connect it to the charger before I can start my phone. If I don't to it, a empty battery appears on the screen. But when the phone is started, I can remove it from the charger and it will still work. But now and than the phone falls out after a while.
At the moment, my phone isn't connected to the charger, but it still thinks that the charger is connected... Picture is attached.
Does anybody here had this problem too? Or do you people know a solution? The problem is, within 2 weeks I go to Sweden for 4 months, so I can't bring in my phone for repair...
Thanks in advance!
Anyone? Or any suggestions? I even can't read the battery gauge, also not in the settings menu. The graph is like a rollercoaster
Maybe you can go to recovery mode and do a wipe, maybe theres a problem with some files.. did you had root and modified something??
I think if you flash another stock rom, fresh, with a factory reset and sd card format, it may fix the problem.. but I havent seen this in xda before, so going to repair centre is good to, but you must be on stock rom and no root or unrooted
Sent from my GT-S5660 using xda premium
maybe you should try to do factory reset before flashing it again
Go to recovery and wipe battery stats and flash a rom with the usual dalvik and data wipes and see if that changes anything.Otherwise idk I never seen or heard anything like this

I had this problem too about a month ago. You don't need to take it to repair center, install cwm (look in the gio big thread for help and dl), go to advanced menu, and wipe battery stats. If that doesnt help, do a wipe data/factory reset.
Btw, i had this too when it was about -15 celsius and i was outside. The Gio doesnt like cold :S

I installed CyangenMod 7.1, an did a wipe data. I also wiped the battery stats. No results. So I think that it is a hardware problem, with the battery... So I will bring my phone to a service center, no other option I think. And flash a stock firmware
Yeah that's probably the best thing to do.Good luck

Sorry for the dig guys but I'm facing a problem. I was running Gio Pro 1.4 on my phone with A2SD and I noticed the battery was draining fast and I saw the key lights were on even with the key lock so I shut the phone down. When I tried to start it again the phone didn't do anything. I took the battery off, tried downloading, recovery, ram dump mode and only the last one worked but after some time it stopped working also. I tried a friend's battery and nothing. I got home and connected the phone to the charger and everything was normal. I could start the phone, enter recovery, etc. Without the charger the phone was the same, didn't start. I tried a hard reset and nothing so I tried to flash to clockworkmod recovery and to cyanogen rom. The installation went good but I still had that problem. Then I tried to wipe the battery stats, dalvik cache, etc and still the same. I then tried to flash the clockworkmod recovery with odin and the same. I then flashed with an original firmware with every file (incluiding modem) and the phone was working good and I could start without the charger. Now I installed the cyanogen and cwm recovery again and the problem reappeared. Help please?
EDIT: Guys, reflashed with cyanogen and it is now working...Weird..
Just a little bump since the problem came back...
Already flashed to and ICS Rom, back to official rom and the problem's still there, even with the official rom. Any help guys? My battery's in good condition, already wiped everything...I can't find the solution...

Back to the original problem of the yellow triangle and not charging. I googled over and over to find a solution, I came across some askme website that had over 30 people say that DROPPING the Samsung Gio from 2 feet will fix it. I decided NOT to do that but slam the phone slightly hard on a desk. It totally fixes this icon (remove the sim and micro sd before slamming it semi hard).
People were dropping it from 2 feet, but I found slamming it (not hard!) fixes it right away. Now the yellow charging icon is gone and my Samsung Gio GT-S5660!

Unfixable boot loop... Help?

Hey everyone,
So this is my last ditch effort to attempt to save my device. I would really prefer not to perform another warranty exchange given that I am not under insurance, but I'm afraid I have no choice.
My phone was rooted and I was using Darkside without issues, as I had been for the past two weeks. I am always careful when I flash roms and I made sure to follow every possible protocol. That's the background information.
My battery life was running at approximately 6 percent yesterday and I sent a text message as normal, and it was stuck at sending. I tried turning wireless data off from the toggles in the pull-down and it was unresponsive. When I went to Wireless Network in the settings option, my phone rebooted. Once it started up again, my service would not come back, and the phone would continually bootloop once it got past the traditional "media scanner running", etc. My window of opportunity to do anything was really slim.
I charged my phone to see if it made a difference, but it didn't. Tried with my SIM card removed and it still bootlooped. I was able to get to CWM from the advanced power menu before it rebooted again and I fixed permissions and cleared cache and dalvik. Now the phone wouldn't even get past the boot animation before rebooting.
I put the phone into download mode and reverted back to stock using Odin. The phone now got past the boot animation in stock mode, but was unable to find service and after about 10 seconds fell into the same bootloop pattern. I tried removing the SD card but that didn't help either. Using Odin again, I reflashed recovery, followed by root and tried reinstalling a rom through CWM (I have only used regular CWM, not the touch version) with a superwipe to ensure a clean flash. Once again, it wouldn't make it past the boot animation before bootlooping. I reverted back to stock using Odin, and this is where I stand.
I have tried all traditional methods to salvage the phone and, for the life of me, I cannot understand what happened. The only thing I notice is that regardless of how long the phone stays on before rebooting, it is never able to find service. It's like the radio or modem broke and the phone has no other choice but to restart forever. But reflashing the stock UVKL1 should also reflash the proper modem and radio, right?
Has this ever happened to anyone? Any suggestions (aside from the typical reverting to stock) as to how I might be able to stop it? I searched but haven't been able to find a situation quite like this one. Thanks in advance for your help.
Really sorry to hear about your problem. Assuming the 2.3.6 stock image you flashed via Odin is the one provided by Przekret and that that didn't work, then I'd try one or both of these two longshots to try to clear possible corruption problems in either the kernel or modem spaces:
For each of the following wipe cache and Dalvik cache in CWM before flashing and again wipe Dalvik afterwards and also fix permissions:
1) Format system (do this 3x) under mounts & storage in CWM. Flash the standalone Darkside kernel X v1 final immediately after flashing, e.g., the current Darkside rom. (You'll need to wipe data, too, if not coming from a Darkside rom. Do not do any Superwipe - neither the standalone version nor using a flag.)
2) Flash the KID modem (do this 3x). Both Odin- and CWM-flashable versions are available. (You can always flash back to KL1 if the problem is fixed.)
Hope this is clear. It's late! These are both things that have helped get my phone out of troubles, though not as bad as yours. Good luck!

Also if u used the one from przekret then I'm almost positive that Odin package flashes the new radio too. If memory serves me right. Op let us know what happened
Thanks for your help. Unfortunately, nothing has worked. I'm on the phone with T-Mobile, I see no other solution but to get it exchanged under warranty and it's not getting here until March 15th, according to the representative. I suppose I'll just use a replacement phone in the meantime. It's just really weird and frustrating... I could understand a bad flash or something similar, but I followed every step accurately as I always have and everything was working just fine until it randomly decided to die without warning.
Well since you're getting another one anyways I would continue trying to fix this one, just in case you come up with a solution and for another worst case scenario for your new phone.

Hardware issue or am I missing something?

So, to start I have not meddled with my phone at all for a couple of months now. I have been using the MikG rom with no issues, and have never had any issues flashing roms or finding the answer to a problem on the forums here. But I am stumped on what my problem is or how to fix it.
Just the other day I restarted my phone, as I said I have not been messing with rooting, it was just a simple reboot. When my phone started up only the top bar loaded and nothing else. I could still get phone calls and text messages and the notifications would update, but was entirely locked out from doing anything other than being able to see the top bar. I restarted a few times hoping it was just a fluke, but the same result every time.
I then reflashed my rom but got the same result. Then I flashed the newer version of my rom, I still could only see the top bar, and nothing else. And yes I wiped all data/cache/davik and reformated my sd card.
Lastly I tried flashing an entirely differnt rom, but that only resulted in putting me in an endless bootloop. I have tried a few different roms and all put me in bootloops.
I am afraid this might be a hardware issue, but I figured I would ask on here to see if anyone had any ideas what my problem might be. Any kind of input would be greatly appreciated :\
Can you tell me what Rom you flashed afterward? I was using mikg for awhile, but it did the samething. I wiped the hell out of it. And flashed another Rom and it works. If you wipe again and it doesen't work, try reformatting your SD card.
Hardware would be like dropping your phone and some of the buttons not working. I think its more of a software issue....

My first instinct was to go back to the roms I used prior. I tried Myn's Warm TwoPointTwo and Synergy since I have used them both and had no issues with them when I did.
And I reformatted my SD Card on my computer
Can I have you pm me your email address?
I might have a couple of zips for you to flash.

[Q] Need Advice...Blank Screen after loading LK 1.6

Hello everyone,
been creeping the forums for the past week...new to the android world but i find the idea of customizing your phone in your own unique way was a good enough reason to leave blackberry after using it for 7years. Anyways....onto my real problem here.
(I appolgize in advance if i mess up the terminology. hopefully you can understand me)
I use a phone on wind mobile (SGH-T999V) and from what i know it's been a safe assumption that if the T999 works then the t999v will most likely work.
I was on AOKP build 5 prior to flashing to the CM M2 ROM...used odin to install CWM_Touch 6.0.1.2.tar then did the steps in
http://forum.xda-developers.com/showthread.php?t=1946701
Edit : I forgot to mention...I can get the screen to go into recovery mode...however, when i press up on the volume key my phone will turn itself off.
and i plugged the phone in again and it decided to be read by my computer.
to install the ROM which worked successfully... however this is where I think i messed up or maybe it has nothing to do with it at all... But my MMS messages did not work so i tried to just play around with some settings and i searched the forums and tried the things that were posted but to no avail. One of the things i did try was to uncheck the privilege unknown applications button and to turn off developers option so USB debugging should be off...or it may have been on...not too sure.
Anyways, so i remembered that I haven't finished the last 2 steps from the "how to flash a rom" in the midst of reinstalling my programs using titanium backup. So i reboot into recovery mode(and this is where i messed up i think) and i wiped my factory data again so after noticing that i did that i went back and restarted the phone and filled in all the information on the welcome screen again. and went back into recovery.
did "wipe cache partition" 3 times AND dalvik cache once then proceeded to install from my sd card the "lk_aosp_jb_tmo-v1.6". After installing i rebooted the device again and i get to see the Samsung Galaxy S3 screen and my screen will go completely black. However, I know it's still on as the battery charging indicator is on and my two buttons around the home button are lit up constantly....out of curiosity i decided to call myself using a land line and the phone is still working (I hope this is good news and that i'm not bricked but teased in a sense i can't fix the screen).
I tried to plug my phone in and it didn't detect it so i reinstalled the drivers and it did detect the phone. I laoded the Samsung Galaxy S3 Toolkit V.2.3.0 in hopes of trying to recover via option 6 "backup and restore your phone" and was hoping to revive it by restoring the nandroid backup however when i typed in my folder the toolkit crashed on me...and now it can't detect my phone as when i try to install the drivers again - the MDA driver seems to fail everytime.
Sorry for the long message...I wanted to be detailed in a sense I don't have to keep giving people more details... your help would be appreciated...Thanks everyone!!
Where'd you get the lk_aosp_jb_tmo_1.6 file from? Never read about it. All you need to do is wipe completely from recovery (data, system, cache...) and install cyanogen and then gapps, reboot.

You can also just odin back to stock and start over from fresh. If you can still get into cwm then just do what he just stated above.

I tried to find a link for the stock kernel but the 2-3 that i found all have 404.
Something tells me i just ran into bad luck with the kernel flash. or does it have to do with me doing a wipe/data reset again and perhaps not selecting the debugging options/trusting unknown apps checkbox before running it through again? I'm not sure...just grasping at straws here to why my phone is doing that.
Anyone else have more ideas?? Anything will help...Thanks again!!
Looking like an Odin is your option here. To flash a ROM/kernel, wipe data,system,cache... flash ROM then gapps(optional for which ever ROM you are on) and then kernel. Make sure you're flashing the proper kernel.

Okay - I'll try it tonight when i get home from work. Here's where my lack of knowledge/noob status comes into play. Thanks for the help.
Do i get into Odin via trying to start my phone in download mode? (I tried to hold the power button/down/home) but that's when i get that glimmer of hope before my screen turns blank again when it asks if i want to continue or reboot my phone.
Or do i try to get it running through Samsung Galaxy S3 Toolkit V.2.3 ?? (If that's the case can you tell me which option i should use to get to the appropriate screen? or should i just launch the odin executable file? (however I'm not sure how that would get anything accomplished if my phone doesn't enter download mode...or maybe it's in download mode when i press up on the volume key but the screen is actually blank? Or maybe i don't understand the process 100%)
But lets say hypothetically speaking I manage to get Odin working. Which proper kernel should i be using? I tried looking for the stock kernel but all the links i found 404'ed. Does anyone have one that works? I'm just kind of trying to get my phone working in general...even if it means going back to stock everything. Pointers Anyone?
Thanks!!
Edit: Forgot to mention the fact that I may not be in debugging mode as i tried to turn that off to see if that had anything to do with my inability to send out MMS msg's as i mentioned in my first post... so that might stop me from using Odin no?
Update
Ok well just an update in case it happens to someone else - I pretty much left the phone alone and didn't touch it for 16hrs. Came home from work and it decided to boot up recovery mode so i just wiped data/cache quicker than a little kid wanting to open Christmas presents on Christmas day when they wake up... Needless to say I didn't bother testing the lk 1.6 kernel so i'm not sure if it works with CM10 running a SGH-T999V (Wind Mobile) phone. I'm trying to think of what may have happened and I'm thinking MAYBE it's because i was charging my phone from 20% all the way to about 95 then decided to plug it into my computer ...so maybe an overheat issue?
Anyways. Thanks for everyone's attempt to help. Much appreciated!

Undo ICS leaked firmware

Is there a way to undo the leaked ICS firmware I've flashed? I've been hit with the post viper CM10 lag that seems to be going around and I thought I'd try everything to get rid of it.

I charged it over night and when I took it off the charger, it was shot again today. When it actually boots, I can't get past the unlock screen. It holds there for about a minute before going into a boot loop. I didn't even think of the ics firmware. Maybe I'll try going back to stock tomorrow and then reflashing cm10.

Is there a copy of the old firmware that is flashable like the new one?

There at threads for different ruu's. I'm not sure which one you need. Search through those. Also, when your phone starts lagging try connecting to a computer in adb I think, someone posted that that fixed theirs temporarily. I think they narrowed it down to the SD card being bad and with it connected it dismounts the SD card and doesn't have the problem. That might help.

Just a quick note...When I was running CM10 I would get the boot loops at the lock screen, but if I just let it alone, it would loop 2-3 times and then settle in. It took a while, and I avoided rebooting my phone at all costs, but have you just let it sit for about 10 minutes to see if it pulls out of the boot loop? Mine usually came out in less than 5, but you never know. After it booted up it settled down and ran fine. I've never used the Venom rom or super wipe though, so ymmv.
