Bricked? - T-Mobile Samsung Galaxy S II SGH-T989

So I found my old s2 and when I turned it on it always boots to safe mode where nothing comes up only screen with status bar and absolutely nothing else. Volume up works only when holding power button and volume down isn't working at all even in recovery so I am unable to get it into download mode or navigate recovery to try factory reset. Is it a lost cause? Or any ideas to fix?

Nope, your phone is fine. Your volume button is stuck, which makes you boot into safe mode.
Open up your phone (if comfortable) and gently wipe the switch for any debris present.

Will try. Thanks

I was kinda weary on taking apart since its still insured but it was a lot simpler than I had anticipated and wiped it down with alcohol pad and sure enough it worked like a charm. I was then faced with android.acore crashing but since I can now navigate recovery just did hard reset and back to normal. Any advice on best ROM and kernel combo and best way to flash? Thanks again

Personally, I like the Hellybean 4.2.2 ROM. It has excellent performance, overclocked GPU, init.d support, overclocking/volting support, and a sick dark theme. (Don't go with the 4.3 Hellybean, it has memory leaks). I'm pretty sure there is a Hellybean 4.4 in beta at the moment, you can check that out if you wish.

For CM10 and abovre, the minimum version radio firmware that you need is UVMC6. If you do not have that installed already, baseband will show up as unknown. Your SIM card is probably not being recognized because of this.
Search for the UVMC6 zip and flash it FIRST in your recovery (CWM,TWRP), before you install any ROM.

Well then, install CWM or TWRP via ODIN, then install the UVMC6 radio zip.
Most likely, your current radio firmware is corrupted.

my issue with this is as follows. i can only odin into stock ICS any other attempt to odin jb or flash custom ROM on it results in constant rebooting during "android is upgrading" upon first boot... wipes have not alleviated this issue. on stock ICS i get a circle with a slash through it no baseband or imei. have flashed multiple radios and they dont seem to stick at all. the one thing i havent tried is flashing an ICS rom like cm9 or such and flashing the radio to see if itll stick that way. so i guess my question is is there a way to fix this issue or could the radio be fried?

Try using Odin 3.0.4. Only version I had luck with flashing stock jelly bean. Before you Odin tho....use the 2 infamous wipes. Cache one and superwipe one. Found in dev section.
Give that a go.

Did you flash the latest TWRP (I believe 2.6.3.1) via Odin or Heimdall? If not, do that first.
Unless your USB port is broken on the phone, it should work and get recognized.
Have you used adb before on your phone?

Using cwm. Will try twrp when I get a few to flash cuz I do know that allows u to use terminal within recovery unlike cwm where I had to reboot into ROM and use terminal emulator.. I haven't messed with adb a lot on the phone.

If it is dying, and the screen and other components are in working condition, you could sell it on eBay for around $85-90.
The SGH-I727 (Galaxy S2 Skyrocket) has similar specs to the T989, and you can find those being sold on eBay for around $100 to $150. I am not sure exactly why it costs lesser than the T989, but it is (and I bought one for my dad for $133 USD). Both have the same specs, same processor, GPU, storage, etc.

Ended up buying a new galaxy note i717 brand new for 200$ I was actually thinking of posting it on eBay. Everything is flawless except seems the motherboard fried but everything else was working. Since screen and case are flawless was thinking of putting it for 100$ too much you think?

Think I killed my GS3. :(

Wasn't paying attention when updating my ROM for a AT&T GS3 and accidentally tried to install the Verizon Equivalent. Original ATT Rom was AOKP Jelly bean.
Anybody have any ideas on what to do? The phone doesn't seem to be able to enter recovery mode, but can enter "Downloading... Do not turn off target !!"

Good thing it seems like the architecture of the US GS3s is similar enough that flashing another carrier's ROM won't result in a nice hard brick that requires JTAG/warranty fix.

[Q] No data/services after kernel flashing

Hello guys, I'm pretty new to cellphone ROM flashing and modifying.
I successfully flashed the Jedi X7.2 on to my Mobilicity Note 2 T889V, and with a little effort I even flashed the Rogers modem on to it and fully enabled 4G/LTE service since I use Fido, they pretty much share the same frequency.
Then I tried the Bullet Kernel 1.9.01b made by cmenard on top of the Jedi x7.2, which then I lost my data, no 2G, 3G, 4G at all.
So I went ahead and tried to flash back to Jedi with all the wipe data/factory restore and everything, still no luck.
I also formatted the entire sdcard directory, trying to start from fresh, with some other types of ROMs such as MyRom and so on. Now my phone even keeps restarting every minute or so.
After a while I started to become frustrated, it was perfect if I've stopped when I got the 4G, any suggestions? I really really appreciate any input on this problem. Thanks a ton

OMFG, punctuate. My crypto devices can't decipher the longest run-on sentence in history!
To the OP, I would odin the original stock image back onto your phone. Then, update to the latest update via keis or OTA. At this point, you are at least functioning again. THEN, maybe try out Jedi.
Side note, why did you try the new kernal in the first place?

Your posts are really really bad. Not to insult you. But ive read some of them and also you give bad advice and frequently dont really know what you are doing yet you give advice to people. ...this is not good.
OP you lost your data possibly because you did not remove the t889 modem from the firmware that you flashed? Does jedi come with the t889 modem....or t889v modem? What about imei number....do you still have that?
Sent from my GT-N7105 using Tapatalk 2
I'm pretty sure that Jedi X has the saber kernal built in...no need to flash a kernel. The developer is packing it with the ROM because it is not ready to be a stand alone kernel in his opinion (last i read anyways)
I'm on Jedi X and I didnt have to do anything to the kernel and my data works fine (minus MMS)
Hes using CANADIAN T889V
dont you think that has something to do with it?
Sent from my GT-N7105 using Tapatalk 2
Thanks guys for the advice. The Jedi was actually working great, and the Bullet kernel is nothing wrong either, it's just the Bullet kernel I added in on top of the Jedi that screw things up.
Mine is the T889V, the Canadian version of T889, so according to some posts the developers made here the only difference is the modem, and that's why the Jedi ROM has a T889V modem patch.
However, as I mentioned, I unlocked the phone and I'm with Fido right now, and Fido uses Rogers' transmitting towers so I flashed the modem of SGH-i317M to get the 4G LTE frequency for Fido and I actually succeeded.
I'll try something out, thanks guys again.
Any other suggestions are very very welcomed!
I got your PM, but this sort of question is better discussed in-thread.
Let's backtrack a little here...
So you've got a T889V flashed with an I317M modem, on Fido, does service work on it currently? What about your IMEI?
Are your drivers correct? You should be seeing one and probably two serial ports appear in the Windows device manager.
Did you try disconnecting and reconnecting the USB cable after changing to DM mode?

Thanking for getting back to me, really appreciated.
To answer your questions:
- Yes the I317M Rogers' modem did work until I flashed a custom kernel on top of the Jedi ROM
- After the kernel flashing my mobile data was gone, and the IMEI became 0
- My drivers are the newest samsung 1.5.9.0 USB Driver for Mobile Phones
- Yes I did disconnect the device before changing it to the DM+MODEM+ADB mode.

your issues is running a modem that is not compatible with the modules you flashed when you flashed the kernel.
this is why it is a good idea to just run things that are built for your device and your device only. you might have to odin back to stock to get your device working again. you should check your settings>about device> and see if your IMEI is still there.... i would suggest sticking with t mo builds in the future if you are not quite sure what you are doing. blindly flashing things without doing some careful reading can be a recipe for a bricked device or permanently lost data/device ID

Yes I can, and it can connect too with QPST, just thar it will show "No Phone" and not be able to read/write anything to the phone.
Try rndis + dm + modem, and make sure Kies isn't interfering?
Beyond that I'm not too sure. What exact drivers load for the ports?

[Q] Werid issue where my GS3 is stuck in Factory Mode

Let me start by saying I've read through several other threads with a similar issue, but they all have a common connectivity problem that I'm NOT experiencing so I thought I'd ask this in a new thread. I was using AOKP build 5, and I decided to try out a more TW stock rom to see how devs have modified it. I chose Intergalactic v 2.8, wiped data/cache and installed like ya do. Almost immediately I got the pop up saying, "Unfortunately, Factory Test has stopped." I didn't think much of it, even though I had never seen it before. I restored my app data via Titanium Backup and starting fiddling with my settings. Made a couple calls, a few texts. Put my phone down to go about my morning. Later when I went to unlock my phone I realized I don't have a lockscreen. Thought that was funny so I went to boot into recovery but punching the power button just turned the phone off; So I investigated and I realize I'm in factory mode. and I can't seem to get out of it. I've tried running the terminal commands to turn it off, but that didn't work. It looks like my ESF folder is empty or doesn't exist.
So here's what I know after all of my research: My IMEI somehow seems to be intact since I can make calls and get on the network, but because my ESF is empty or gone can't turn off factory mode, which is causing all kinds of other buggy issues such as no lockscreen, no power menu, and the annoying Factory Test pop-up. If there is a thread out there that had a similar problem, I apologize that I couldn't find it. is there any way to recover this info, since the IMEI is still intact? Thanks.

Tried to restore the stock JB with Odin and it didn't fix the problem. I'm attempting to flash the stock ICS, then attempt an OTA update to see if that does the trick. Will keep you posted.
So I flashed ics and then allowed AT&T to push my JB update to me OTA. Still in factory mode. I guess I'll just have to investigate this more thoroughly. I'm using widget locker as a work around for my lockscreen, but still no power menu and the popups are still showing up every now and then. Super annoying, but at least my phone is still functioning. If anyone has any other ideas I'd greatly appreciate it. Thanks.

Don't be skittish. It really and truly is the only way to get everything back to how it should be. Ton's of people have tried it and this allows you to push the IMEI back into your phone the way it came from the factory. It's not for spoffing or doing anything illegal.
Now its usually for replacng a lost IMEI from flashing a ROM. Sometimes happens when going from a non-stock type ROM (i.e. CM or AOKP) to stock type ROM (i.e TW)
Search on how to push files with ADB and you should be good to go
BE CAREFUL though and don't skip steps or go fast.
I meant to ask...can you use your phone ? does data work ? Have you tried to get into download mode ?
If you can then download good manager and select reboot into recovery or any other number of apps that let you boot into recovery without having a power menu

I tried turning it off with terminal emulator at one point last night, but it didn't seem to work, I THINK because the EFS folder is empty. I'll have to re-root tonight and try it again since I've restored my stock firmware.
It may seem like I'm shooting down every suggestion you guys throw at me, but I really appreciate the input. XDA is a big place and I tried to be very thorough when searcing for a solution before posting this thread, but I'm sure there's something out there I've missed. Thank you for your efforts.
I think I found something that will allow me to restore a generic EFS here:
http://forum.xda-developers.com/showpost.php?p=39523753&postcount=4
Asked the originator if it will work to restore my files. If so, gonna try it when I get off work tonight.

Ah exactly what I have been looking for on this one for you. I found a few that explained how to push your old EFS folder with ADB but none about making another. How crazy it was yesterday it popped up on a post. That looks like your best shot as you folder seems to be corrupted and although IMEI is intact you need a new one folder that is intact. Let us know how it turns out
Can you hit me with the stuff you found about pushing it through ADB? My efforts have been less than fruitful on that front. I'd rather be armed with as much information as possible.

Have you looked at this ? (or is this just the same thing as turning it off)
- One more thing, what file explorer are you looking at the efs folder with ?

Boot Looped - reboot nvbackup

So, I was working with a friends SIII and I read about running reboot nvbackup. Like a dumba$$ I decided to run it on my N900T in terminal and now I'm boot looping. I've Odin'd back to the stock ROM with no resolve. What did I do and how can I fix it?
TIA

Before you Odin'ed back to stock did you do a full wipe using TWRP/CWM which includes:
"Wipe Data", "Wipe System", "Wipe Cache", "Wipe Dalvik Cache" and last but not least did
you do a full "Factory Reset" in TWRP/CWM ?
After doing all the above your phone should no longer boot loop, what it should do after doing
the all the above is to go into download mode and or recovery mode.
If it boots into download mode then odin flash the official stock rom which must match the specific
model number of your phone. After doing that you should be good to go.
Best place to find and download the official stock rom is at " SamMobile.com ".
The only roms that SamMobile.com has are the official stock odin flash firmwares which
displays exact baseband (model numbers) which needs to match your phone's baseband.
Good luck!
Thanks for the reply. I've done what you have mentioned, but still boot looping. Trying other methods that I've found and will report back unless someone has any other suggestions. Primarily, I'd like to know what the reboot nvbackup actually did.

I skimmed through the thread on nvbackup and it seems like you borked your efs/IMEI. Could be wrong, I only scanned the thread... This was made for the S3, why would you do this to your Note 3?? Anyways try this thread here: let me grab it real quick..

From the ADB shell: Wiped the EFS partition with the following command:
mke2fs /dev/block/mmcblk0p12*
mkdir /efs
mount -t ext4 /dev/block/mmcblk0p12 /efs
(the last two commands probably did nothing, but thats what I did anyway)
Did a Factory Reset*
Then... reboot to system
Afterwards, no more boot looping, the phone successfully registered on the mobile network, and my IMEI is there and correct. Seems like the EFS partition can rebuild itself now I guess...

I did it because I'm a dumba$$...no, really...it seemed innocent enough to me...no files to load, etc. Lesson learned.
Anywho, yes, I've also tried that one too to no avail. Just since it is already borked, I ran the reboot nvrestore and that locked it right up to the Samsung Galaxy Note 3 screen. I then Odin'd back the original factory rom and tried the above steps again. Back to boot looping. I would imagine there is an answer since I'm able to get into recovery, but I just need that silver bullet.
Thanks for trying though.

Hey zonly1, were you able to fix your note 3? I'm did what you did.
No, I'm still dead in the water.

Hey guys, I did the same thing on my note 3 and I tried everything to fix it but in the end I was still within my 14 days and I took it to the store I bought it and swapped it out. At this point you have a couple of options, call Tmobile and do a warranty swap or go through samsung directly. If you go through samsung expect to not have your note for about 1-2 weeks.

Broken note3's aren't funny. Mine was broken for over 6 weeks, I didn't give up, and today I figured out how to fix the FSG partition that Samsung left vulnerable by the toxic "reboot nvbackup" command. Hope one or two of the guys read my fix and get their note3' gowning again
It wasn't meant to be funny as in ha ha, but rather a doubtful funny that anyone in the thread still has this as a problem. They would most likely of had the issue fixed or replaced their phone by now. Going on now more than 60 days is a but long for most here for a working phone.
I do commend you on coming up with a solution, most don't have that kind of patience.
this is no joke as you all have stated, it's an easily caused brick, but it would have equally been as easy to look up if this unfamiliar command (at least to me) would cause a brick/loop. I'm familiar with adb but had no idea that's a problem samsung left. please let me know of a fix or provide me with a device dump for those partitions, I think it's mmcblk0p's 12,13..17,18, thanks in advance

Read a zillion threads, nothing sticks

So I've rooted my phones for the last 5 years, nexus 1, droid, rezound, gs4, n5 and then the m8. finally i screwed up, and i was getting bootloops. in my slightly panicked state i managed to wipe the OS completely off of the device.
i can get into fastboot and from there also TWRP recovery. i've read a million threads, adb sideload, One_M8 all in one kit, etc....
I can't figure out how to now simply flash a stock ROM onto my device. can anyone spell it out in a way this idiot can get it? i;ve downloaded a gazillion things. i'm stuck. i had to go pay full retail for a phone because as a realtor i simply can't be without one even for a day. it's my lifeline. i'd like to fix this one so i can return the new one and save $700.
thanks.
When you say you wiped the OS, did you also clear the partitions? Are you booting into recovery by flashing TWRP and then booting into recovery... or are you booting into recovery via "fastboot boot"? If you have partitions still, you can use a USB OTG adapter and memory stick (or just sdcard) to store the firmware.zip file and flash it from TWRP.
IF, on the other hand, you wiped your partition table, you are in a bigger mess. It's possible a RUU can help, but I'm not familiar with them so can't comment beyond suggesting that you look into that more...
In the development section there is a system dump by (Mike1986). If your computer still recognizes your phone, download system dump to computer, copy it to your phone's internal storage, get into twrp and flash.

How would you go about copying to the phone's internal storage?
After downloading Rom right click on it select cut, go into your phone's storage on computer (as long as computer recognizes phone) find empty space right click and select paste.

Well considering your not the original poster, and I've read the original post several times and can't seem to find where it says it doesn't boot into android. I'm just trying to offer whatever help I can.

There is a DEV RUU out. You can use that. Or if you want ATT, or GPE, find the zips, and use fastboot commands to flash. If the computer can see the phone and you can issue commands, then there is nothing to worry about. Been there done that dozens of times with the M7. After playing with this M8, seems to be the same. Let us know where you are stuck, i.e. don't know the commands, or don't know where to find the zips.

He wiped the OS, which is Android, thus he can't just plug it in and transfer files back and forth anymore.

Surely if you've only deleted the OS just flash a nandroid from the stock backup thread via TWRP?

Have you got an external sd card? whack it on there using a card reader and flash from external sd
---------- Post added at 11:04 AM ---------- Previous post was at 11:01 AM ----------
If that won't work on TWRP use philz
not sure if i wiped the partitions. don't think so.
i can't transfer files to the device, the pc recognizes it to give fastboot commands via a command prompt, but not as a removable device.
i'll get an sd card on my way home today and try flashing a rom using recovery.

oh pretty cool. i have the sd card now and going to try. otherwise i may take you up on your offer.
anyone have a link to the right ROM zip file to flash for AT&T version phone?

very strange. after flashing and rebooting, i didn't have a clean install of Android, all my customizations and apps from before were installed. and i got the same random reboots. so all that info was still on the phone. went back into recovery and wiped everything, then re-flashed. now have a fresh clean install of stock 4.4.2
Thanks everyone! i kinda thought the sd card thing would be the easiest but the comments in this thread confirmed it and it worked.

That's the beauty of the sd card slot mate, i have saved my m8 countless times. i would always make a backup of your phone prior to tinkering but this really helps save ur ass if you forget to backup.
Glad everything is ok and that this simple solution worked :highfive::good:
