Galaxy GT-I9100 yellow triangle/no boot. - Galaxy S II Q&A, Help & Troubleshooting

Hi guys, I wanted to root my Galaxy S2(ICS) today but also keep the stock ROM.
I first followed a tutorial which had a Kernel download link to "jeboo_kernel_i9100_v1-2a". After reboot the yellow triangle appeared and that was all. It didn't boot up it just simply went black screen. I have like 30 tabs open looking on how to fix this, but couldn't find a fix. (maybe I'm illiterate and that's why). So I decided to try another kernel this time Siyah-s2-v4.0.1. Still the same yellow triangle and then black screen.
What I was able to do:
Vol up + home + power and Vol down + home + power. Both of these work, and the phone is recognized in Odin.
Now for some reason it gets stuck at the yellow triangle screen, and only the vol down + home + power combo works so I can still get it in Download mode. After trying some more the Custom Binary Download went up to 4 counts.
Any help is apreciated.
Thank you,
Zeros000.
Edit: Okay I tried again, now with the newest stable Siyah kernel "Siyah-s2-v5.0.1". This time it either loops in boot or stops at the Siyah logo.

your best shoot is at flashing a stock Rom then root using another method and then use triangle away by chainfire

On ICS, ExynosAbuse.
Can you get to recovery, do a couple of wipes, first dalvik.

Can't get into recovery just Download mode. Will try what @Blackwolf10 suggested.

If u see 'Siyah' logo then u can access its recovery for sure
use the volup + home + pwr button combo to get there and once there do a factory wipe and restart the phone

Yeah... I said I can't get in it because I already tried, not because I don't know how. I can hold this combination for minutes it still wont go into it.
EDIT:
Okay, I tried CF-Root-SGS2_XX_XEO_LPQ-PROPER-v5.4-CWM5. It failed. I tried I9100XXMS1_I9100OXAMS1_XEO, still failed. And I still can't get into recovery, just download mode. But now the yellow triangle is away.

Are you getting a pass in Odin?
If so either you're flashing the wrong ROMs for your device or you need to try other ports.

Yup, I'm getting pass. Can you help me out finding the good ROMs?
By other ports you mean USB port? Well I'll try that untill further replies.
Phone details:
GT-i9100
CSC XEO
PDA and Phone I9100XXLPB
CSC I9100OXXLP5
Under the battery it says:
GT-I9100
-I9100GSMH
Thanks.

Where are you getting the ROMs?
Try this: http://www.sammobile.com/2012/11/15/i9100xxlsj-–-galaxy-s-ii-android-4-1-2-jelly-bean-test-firmware/
(don't flash the pit please, just csc, pda and phone).
If Odin passes, then you're looking good.
Remember to kill kies applications and antivirus.
And yes, I was talking about USB ports.

Meanwhile I tried different port with Siyah latest version. Same result with yellowT but this time it's not looping it's just sitting at the Siyah logo. The phone only gets stuck at the YT when I try recovery mode, and then loops.
(meanwhile downloading that rom)
OMG, after the 2nd loop it started up. I hope that it was the different port because then you are a HERO :good:. I should have tried different port too, but seems the keyboard port is still better than the ones in which I plug in usb's most of the time.
Thank you again, I'll post again after it finishes and see if it's working. Btw the XEO rom I've got was downloaded from sammobile.
It asks for Sim network unlock PIN. I have Orange Romania sim in it.

Phone is stuck at lock screen, I know that it's on because I just tried the radio, then left for a minute. When I came back the radio is still on but unable to turn on screen. Also I know that reboot wont help as it happened the first time too when the sim lock came up, while I wrote the previous post, the screen normally went off. And when I tried to turn it on it didn't. After the reboot I didn't let it go off and it worked until I left. Will reboot one more time.
I looked around and this might be the problem... ooops:
This kernel is only for Samsung JB ROM (No ICS support anymore). Although the kernel boots CM10.1 I will not support it until I fix dualbooting.

This is on Siyah's blog, could this be the problem? Restarting... Got stuck again at the logo... Restarting... Now it works again. I wonder if the screen lock is affected by this.
EDIT: I have Jelly Bean, seems like the last ROM I used was JB, so it's not the unsuporting problem. Also someone else suggested me Galaxy S2 SIM Unlock it worked and it was a free app, but thanks. You are really helpfull.
Edit 2: Okay nevermind, for some reason it works now... It's not reasurring but it works.
Thanks all of you for the great help. I don't think that I could have done it without @gastonw and the owner of jayceooi.com webpage (from where I tried the tutorial) who replied to my questions under minutes.
If anything happens again I'll know where to find people who want to help.

You can find galaxysim unlock for free here, at xda.
It's always good to go stock to check things out.
You only go custom if EVERYTHING seems fine.

I found YT-away free here at xda. I will get rid of that and the count number then leave it be.
I love the stock so far, but I only glimpsed for a moment at a custom one and had to close that thread... I don't want to deal with this for a while . Though some of them look awesome.
Edit: hum a big warning saying this could potentially brick my phone... ugh right now not sure if I'll even use YT-away.

Reflash stock or get mobile odin.
Mobile odin pro will get you rooted and clear that sign, only 5 bucks.

[Q] Will not boot - flashing black screen

Received a brand new Ace yesterday, and immediately rooted it with super one click with no problems.
However I then tried to run the 'Galaxy Ace Unlock apk' which I'd found elsewhere.
It generated an unlock pin, but after rebooting it stuck on the Galaxy Ace flash screen. After 5 minutes I pulled the battery out, waited, then rebooted. Now it doesn't even get to the Galaxy Ace screen when switched on.
The screen backlight comes on (with a black screen) for a couple of seconds, then off, then on - but it never gets any further.
So far I've tried
- Flashing Stock Froyo via Odin
- Flashing VillainRom via Odin
In both cases the phone enters download mode, Odin completes all steps without error, but on reboot I am left with the black screen of death again!
Anything else I could try?
I have the same problem.
Have you found a solution?

Hey!
Dose you RESET FACTORY SETTINGS and FORMAT CACHE in recovery, before flashing with ODIN?

Did the light lit when you entered the download mode? That's the indicator.

Just send it to the service center.
No other recovery method is know.
I have been in every forum arond for this kinda brick and there is no solution for YOU to do. Also there is absolutely no way for Samsung to see either say that after the first boot the battery went dead and it never started again. It will be covered by your warranty and brand new ace! Now dont go making stupid mistakes again hope i helped

Apk/sim bricked my phone.
Unlock Apk also bricked my phone in the same manner.
The app generating the code is not the problem on it's own, it's when you put the "other" Sim card in and reboot that does the damage.
I got a buzz when i could still get Download Mode and Odin gave me a PASS when i reflashed, but alas the phone never rebooted and it still flashed black at me.
I'm trying everything to bring it back to life before it goes to the Service Centre and i have to give them some blag as to why it's bricked.
Other than Download Mode i can get "Emergency Dload Mode"(ARM9) & RAMDUMP.

Even Samsung don't have an easy way to repair it, hence they replace the mainboard to fix the issue.

i tried flashing it and ionstalling a rom for the first time but it froze halfway through for like 3 hours so i just unplugged it and now this screen comes up...
no whenever i turn it on it gives me a screen with :

you are really not giving a lot of details here...all you are saying you tried installing a rom and then it froze halfway..
Are you rooted firstly?
If you are have you flashed CF-root kernel?
How did you try to install the rom?
More info and then more people can help you out buddy..see if you can get into recovery and restart your phone.
well... if you've tried "every" (its not like there are a lot) button combination... then just go buy a jig from ebay and force it into download mode...

Nothing from what you said would help..
He obviously flashed it with Odin, and he said he's getting a yellow triangle with a computer behind it..
From what I understood, he could get into download mode.
So just boot into download mode and flash stock ROM. That should do it.

anyone else seeing an increase in the "i bricked my phone" threads?
dont think its coincidence they are increasing after the american variants have been released. People need to check what model they have before flashing things.
OP: not saying thats what has happened to you as you dont say if you have the i9100 or not, hopefully you do.

its ok and same goes by my post as well buddy..we all been in his position one way or the other
1st - Your phone is not bricked if it show an image. Whatever image it is. The only real software way to brick your phone is to flash bad bootloader or stop a bootloader while they are being flashed. However, Bootloader are flashed first. So if your phone stoped half way, you should not have trouble too much.
Remove the battery from your phone for like a minute, then reboot your phone in download mode (vol- + home + power and when the phone light up, release power.) Then flash another rom from odin.
Also, what rom did you used ? If you flashed a rom for another phone, then you might have flashed bootloader for that phone on yours, which is bad. In this case you will surely need a JIG.
sorry im new to this whole rooting/flashing thing. i downloaded the lightning rom: http://forum.xda-developers.com/showthread.php?t=1095274
i have never rooted or doneanthing to my s2 before. all i did was follow the instructions on the page and thought it would be all good? it froze about a quarter of the way there in odin so i just took my phone out.
I usually find from this state I can get back to bootloader or download states
push and hold vol+ and home then power for bootloader
push and hold vol- and home then power for download
sometimes the phone can seem to freeze a little or even die (this happened to me loads on the galaxy s and once already on the s2) and removing battery sim etc or attaching the charger can jog it
however as other have said a JIG is your friend if for no other reason that even if you recover without it, custom roms up the rom count which some twitchy carriers might invalidate your warranty for, the jig will reset this
you can get them from ebay for less than £3 delivered, or there are instructions on this site for making them yourself if you are so inclined.
simply search 'galaxy s2 jig' on ebay mine was delivered today from portugal as I am way too lazy to make one and only wanted a counter reset anyway

bricked my S3 ? Completely dead

Just got the phone today. I rooted it, applied CM mod, went back to stock, then tried to install the Energy HD2 mod to check that out. Installation failed and now it will not even start / turn on. I tried putting it into upload mode, download mode, straight up hit power and turn on - and nothing works.
Any recommendations?
EDIT: Why can't I post a reply to someone here? I see no reply box and it says 'You may not post replies' and 'You may not post new threads'?

First of all, why the f... are u flashing so many roms at [email protected]#$$%€£…
Now the air is clean. Can u get into download mode? If yes,then go to samfirmware.com and register then download LFB rom to your PC and flash it with Odin, then root it with cf-root.
now DO NOT FLASH ANYTHING ELSE FOR 24 HOURS. let the phone settle.and instead read the OP and check screenshots of the different roms and find one. Also check out the "apps & theme" forum and look for suitable theme instead of flashing a full rom.
Ps. If u can't get into "download mode" then order a USB JIG(301 ohms exactly) from ebay.
Good luck.....but stop your flashing mania or your phone is a goner.
EDIT: Pull out your battery for 20 min,put it back then use 3 button combo to get to download mode..
Btw cm7-9-10 is for experienced users not for noobs.

1. I'm not a newb.I've been running CM nightlies for over a year.
2. The feature sets for the roms are different and I don't see why I can't try them. Energy seemed more mature for the S3 and I think I would prefer a stock-based rom that just cut out the bloat.
3. Tried the battery pull thing. Odin did not recognize a device being connected. It was like there was no battery in it at all. The USB JIG idea sounds interesting. NExt time I have an issue, I'll look into that.
4. Thanks for your help but the new phone is here today and the brick goes back.

hi there
hello ^_^ my first post and make sure you leave your phone charging for at least 2 hours and try again because it happened to me too and i panicked

AT&T Galaxy S II Black Screened

Agh!
I recently rooted my SGH-I777, flashed it using Clockword Mod Recovery, and then rebooted into recovery using CWM. But instead of rebooting into the recovery menu, everything went black. Now my phone won't reboot into recovery mode at all (not even with the Volume Up + Volume Down + Power combo). Instead, it gives me the Galaxy S2 GT-I9100 startup screen with the yellow triangle and then the screen goes all black, with quick flashes of dark gray.
When I removed the battery (to get it out of the black screen loop), returned the battery to the device, and plugged it in (without powering up the phone), the "charging" screen with the charging battery indicator flashed on the screen for a moment, and then back to all black flashes.
I removed the battery, SD card, and SIM card for about 20 minutes because I've read that can sometimes help. No dice.
I'm running ICS 4.0.3 with a Siyah 3.4.2 kernel.
This is probably either really bad or no big deal and I'm lame for not figuring it out, but... HELP! (Please? :fingers-crossed: ) I know this has been asked, but the other threads I've found have been able to get to recovery mode, whereas I can't seem to get to that point.
If you need any other info, let me know!

CWM= hold both vol, then hold power, let the first screen blink once, come back, then let off power is my trick.
download, you can just hold vol buttons and insert USB belive.
Somebody used rom manager!

A-ha! Ok, so definitely no on the CWM combo, but I do get a menu using DL mode. Thank you. Seeing at least a menu made me feel much better.
I re-flashed the initial kernel, but no change. Still stuck in perpetual black screen boot loop.
I'm not opposed to doing a full-fledged wipe using Odin, if that's an option, but I've never looked into it before, and I'm currently feeling pretty gun shy when it comes to getting creative with any new tricks.

If you want stock, flash a stock ROM, or stock with root, with Odin.
If you want custom, after you flashed that custom kernel, you CAN get into CWM and flash a custom ROM.
and NEVER use ROM manager, hell it was a joke when it came out, sorry koush
EDIT:
and if you do go custom, dont forget to wipe data/factory reset in CWM before flashing.

You rock. Thank you a ton for being so patient!!
To any other fool who gets into the same mess, I went into DL mode (volume up + volume dwn + usb attached) and opted to let this do the rest of the work because it was the only option that didn't give me a heart attack: androidarea51.com/samsung-galaxy-s-ii/samsung-galaxy-sii-(sgh-i777)-att-only/
From there, I had the option of rebooting, initializing a factory reset... all of the menu options I wasn't seeing when I couldn't figure out how to get into CWM mode. Good luck!!

I know, I know (and this is a dumb excuse, much like using rom manager in the first place), but the tutorial I was reading made it seem like it was a good option. I hadn't used it in forever and logic coupled with faith in a perpetually broken system paves the road to hell, but I figured, "There's no way it still sucks as badly as I remember!"
Don't think that. Ever. My mistake.
Charge the baterry externally thats what I did when my old infuse was bricked

Samsung Galaxy s2 i-777 does not turn on
okay so I read through this thread and I still don't know how to fix my issue. I rooted my phone using Odin v 1.85 and used siyah 3.4.2. I did it successfully and everything was good. I then gave the phone to my cousin and he said he performed a factory reset to get rid of everything on the phone ( contacts ,etc). Now when I turn on the phone it shows the samsung galaxy display with the triangle and then the screen goes black and just blinks. It still goes back into download mode I just dont know what to do to fix the problem. I know I'm a noob but please HELP!!!

Have you tried flashing back to stock using odin? BTW it is not good etiquette to necro a thread that has been dormant for almost 9 months.

O2 UK original Firmware for Galaxy S3

Hi all, I have tried to unlock my galaxy S3 gt i 9300, which is locked to O2 UK. I live in Ireland and bought the phone from a guy on e bay. I got the unlock code from two different sources and both are the same, but neither will unlock the phone, I have tried the unfreeze code too but it gets me nowhere. Entering the keyboard codes does not work either. The firmware baseband version which is on the phone at present is I9300XXUGMK6, the build number is JSS15J.I9300XXUGNA5, I feel that if I can get the phone back to it's original O2 UK firmware then I might be able to unlock the thing. My problem is that I have found I9300XXALE8_I9300O2UALE5_O2U to be the original firmware, but the link to it from every site is dead and I cannot download it, all the links were to hotfile and we all know what became of it. If anyone has any other suggestions as to how I might unlock my phone then I would be more than happy to try them.
Best wishes Wez
Flash the latest o2u, root it with cf autoroot, nvdata unlock method. Do not attempt to go back from 4.3 as you will half cabbage your phone. The efs changed.

Many thanks I will try that now and let you know how I get on, though the guy I got the second code from tells me the phone should not be rooted, if it is he says that the code will not work. But anything is worth a try so I will try it before I root the phone.
Thanks again best wishes Wez

At the risk of sound stupid, I am going to ask one question, where do I find said latest stock ROM for my O2 UK S3, because all the ones I find are not on any link that works, they nearly all try to send me to hotfile, would seem that nobody has taken the trouble to put up any mirror download links, which has left me very frustrated. Hope someone can please point me in the right direction, because I have a phone which is of no use to me.
Best wishes and good luck Wez

Many thanks am downloading the latest rom from there now, hopefully this will do the job. I will not be able to try it till tomorrow morning as it is very slow downloading, but I can leave it all night and use Odin to flash the phone.
Good luck Wez
Samsung updates are always on slow hosts. It costs a lot of money to hire server space and free hosts that do over a Gb is as rare as hens teeth.. how did you get on?

Many thanks to all who helped with my problem, I managed to get my s3 unlocked, just need to get it rooted now and get rid of the stupid thing keeps going to safe mode when booted normally, but if I boot whilst holding the home key (the middle one at the bottom) then the phone will try to boot into download mode, I then hit the volume down button and hole the home key again, this time the phone reboots itself and will boot into a non safe mode. Though this is not ideal and someone needs to find a cure for this, it is better than nothing. Tried to flash the resurrection remix ROM, but it stopped when a bit was done and failed will try some other custom ROM when I get the chance, at the moment my phone is keeping going back to the recovery screen.
Will let you know what happens, best wishes Wez

To get out of the recovery boot lock I had to leave the phone with the battery out of it for about 5 minutes, I was then able to get into download mode, by booting with the volumes down and home buttons held. I then used Odin to reflash the stock firmware again, which it did OK.Then I needed to root the phone again so I did that. I then downloaded the Android Revolution DH-SGS3, moved it to the external SD card, rebooted into recovery and flashed it to the phone, but again the phone went into it's crazy recovery boot loop, at the moment I have the battery out of kit and will try replacing it now and booting into the new ROM. It appears to be booting into the rom now, it has been on the Samsung screen for a while now and I am hoping that it will boot into the rom given a little time, this being it's first boot. OK all booted up OK, the only problem that remains is the bleeding thing booting into safe mode, but lots of people have got that.
Happy days, best wishes Wez
I have never encountered that issue before. When exactly did the boot issue start?
Glad you got this far!.

The boot issue started after I had tried to flash with another rim, which I feel was not fully downloaded, at any rate the flash was abandoned and when I went back through the options and hit the reboot now, it went into the loop. I had to remove the battery and leave it out for about 5 minutes, less might have done, when I reinstalled the battery, I went into download and using Odin flashed the phone with a stock rom and rooted it, then I flashed the android revelation rom, the phone again got stuck on the loop, this time I took the battery out the phone and left it, again for about 5 minutes, then replaced the battery and hit the power button and the phone booted into the rom, after a few minutes. I have been using this rom for a while now, but have noticed that for some reason the sound, for everything goes of completely, nit found a cure for that yet, but I am downloading the Echoe rom now, it will soon be finished, and I am going to flash it as soon as I can. I have the Echoe rom on my SGS4 and like it very much. I shall let you know if I have the same problem with this rom, when I flash it, the loop that is.

The Echoe ROM flashed without any further loop and to my surprise the phone did not boot into safe mode, so an improvement there, with both. But the sound is still a problem. I have since the first boot had to reboot several times and the damned thing is back to the bloody safe mode. To get round it now I have to hold the volume down, the home and power keys, to take me to the screen for download, when there I push the volume down and the phone goes to reboot, in it's own, while it is doing that I hold the home button, the phones boots without going into safe mode. I have tried to do it the way I was before, but it is not working that way now, so got to go down the way of booting into the download screen, but at least it works.
Very best wishes and good luck Wez
Interesting.. it would seem that the issue lies with custom roms. Which recovery are you using? Cwm 6032 is a good recovery to start with, moving on to 6047. I had issues with twrp.
