Massive Balls Up

I tried to root my phone. Made a massive mess of it, ended up flashing the ROM to the bootloader. Now my phone is hanging on the start up screen. NOT a boot loop. What am I meant to do now to get it working again?

Hey guys,

First up: I have trawled the forums for about 10 hours now and this seems like the most appropriate place to post my request. If it's not, then please direct me to a suitable thread.

My device is a Galaxy S2 i9100.

Baseband: i9100BVLPB

When it was last working, I was using:

ROM: Root Box

Android: 4.2.2

Kernel: 3.0.31-CM-gd4ad65f

bajee11@chaos#4

Tue Mar 12 17:28:05 CET 2013

I've been running Root Box for a while. I fancied a change so yesterday I installed the latest build of Cyanogenmod, along with the Gapps package. After rebooting, my phone is now stuck in a bootloop.

My home button is completely broken, and so I have no way to get into recovery to restore from a backup. I've always accessed recovery mode by rebooting from within the ROM.

I have found that by holding the volume down key whilst powering up the phone , I can get into download mode with no problems. Works perfectly every time without having to use the home button.

So here are my questions, which I would incredibly grateful if anyone could answer:

Am I correct in thinking my only option is to flash a stock ROM using Odin? If so which one?

Will this change my kernel? If not will I need to flash a custom one? If so, which one? I've seen Philz kernel mentioned in the forums, any good?

Will I lose my network unlock? (Done using GalaxSimUnlock from the Play Store).

Will I have to root my phone again?

Anything else I should be aware of? i.e. how my phone got stuck in a bootloop, seeing as I have installed Cyanogenmod successfully before.

Thanks very much for your time.

You need to replace button mate. Use a jig to force it to download mode but may not work and if you need to get to recovery still you wont be able to. So replace Button soon as
[Galaxy S II Q&A, Help & Troubleshooting] jellynova:
Thanks for the reply.

I can get it into download mode by pressing the volume down key as it boots up. Tried it a few times and it always works. No need for home button.

Also when I reboot into recovery, (which gets me into CWM), the power button is used for selection, so surely I can use that to restore from my backup?

I have looked into replacing the home button, it looks like a pretty intense job, with a risk of breaking the screen. I've been using soft keys when the phone works and I think I'd rather stick with that for now as I've become pretty used to it.

So if install a stock ROM, could I then reboot into recovery and access CWM to restore as I've always done? Or will a stock ROM change my kernel, and remove CWM in the process?

Cheers

That is a type of forced Download mode mate. Simply connect your device like that to Odin and flash a stock rom. :)

Have you tried doing a factory reset after flashing rom? If that doesn't help, flash a 3 part rom via Odin. :)

Flashing a stock rom will change your kernel to stock, remove CWM recovery and replace it with stock recovery.

You will have to re-root your phone again. :)

Bootloop + Battery Charge Loop + others

I've had my phone rooted for a while now, but about 3 days ago i started having troubles with it again. The first thing I noticed was that when I unplugged my phone would still act like its charging... but then my S2 completely froze, went to reset and have been stuck in bootloop ever since.

I have factory reset my phone in attempt to fix the problem but still have the bootloop, I have also ran through the steps up to connecting my phone to Odin 3.07 but i get no colour under ID:COM

What do I do now?

Hello,

My Samsung Galaxy S2, stuck at boot screen "Samgsung Galaxy S2 GT-i9100"

I use version 4.1.2 official firmware and I haven never done any root or custom modify software.

I happen after my battery was run out and I tried to restart this morning.

I bought for second hand so I don't have warrantee to send to the Samsung center.

Is there any way to fix by myself?

I tried to flash my firmware via Odin follow this instruction http://xdaforums.com/showthread.php?t=2365701

my problem is that I don't know what is exectly my firmware code or region, I did tried the on for Nordic country because I live in Sweden.

And also, I can't get into the recovery mode (Voulum+ and Home and Power) as mostly the instruction said.

I listend to http://www.youtube.com/watch?v=2LjoFSgLlds .. he said I should clear cache ... but I don't know how ?

Is there any suggestion or method that should I tried?

Looks like a faulty or dirty USB port. Try cleaning ur USB port using a fine brush or by blowing air. Be careful not to bend the pins or make it wet. :)

You can flash any firmware mate. The nordic one would do. If you have trouble flashing, check out [MENTION=4851213]Hopper8[/MENTION]'s odin troubleshooting guide here on XDA. To clear cache, you need to enter recovery mode. :)

Just for clarification I have two questions:

My SII won't let me load recovery mode and factory reset, is this going to be an issue.

Secondly, does using ODIN wipe everything including media (photos and video namely) or just contacts, messages etc.

Cheers
[Galaxy S II Q&A, Help & Troubleshooting] Sun90:
For recovery mode u can always install a Custom kernel like 'Dorimanx', 'Philz' or 'Apolo'.

Well when u do a 'Odin' flash it will not wipe any of ur Media (Photos and Video) for sure since it only wipes ur Data on the System partition, hence u will lose all ur contacts, messages etc:)

sorry for reviving an old thread...

hey guys.

got a problem... Ive been flashing rom's for a long time on all of my previous phones htc's mainly and on my LG G2 current handset. All goes well 99% of the time. I dont post too much because i usually dont need to i mainly just read and copy and it all goes well.

So I've read every single thread i can find but I'm still struggling I'm just hoping someone picks up this and is able to assist...

So I've got a win 7 laptop 64bit. I've tried every single driver known to man since the phone stopped working none of which will let the laptop see the phone - usb device not recognized - I've tried about 20 cables Samsung and not new and old. i've tried probably 20 different sets of drivers as well all with the same result. I currently have kies 3 installed also - doesn't do anything because it doesn't see the phone...

I have an gt-i9100 sgs2. It was rooted some time ago by me before i gave the phone to my partner and put onto blade elite with Siyah kernel.

I recently tried to wipe it and put on neatrom lite as blade elite wasn't to my partners taste. The phone went into cwm recovery and i flashed the ROM fine following all of the instructions (which i already knew).

I am now unable to get to recovery mode at all what-so ever no matter what i try - download mode works perfect. If i try recovery mode the phone just continually reboots and stops at that screen will not go any further - almost as if i have wiped the recovery off some how?????

I am now stuck in a boot loop showing just the black screen with white Samsung logo and the yellow exclamation mark.

As i explained i have been through at least 200 threads and tried everything from cleaning bits of the phone to holding buttons and adding the battery after etc etc etc

I cannot flash a new ROM and recovery with Odin because the PC wont see the phone and i cant turn on debugging if the phone wont turn on so I'm stuck here.

Anyone got any ideas to get the phone back up and running i can send it away for replacement if i can get it to come on but i cant get rid of the yellow triangle without getting it to boot into a ROM.

I hope someone has a bit of help for me....

Cheers guys Nibbzy!
[Galaxy S II Q&A, Help & Troubleshooting] andrewwright:
Debugging don't matter mate. Have you tried a different PC. Read [MENTION=4851213]Hopper8[/MENTION] thread about failed Odin flash. Great info on there.
[Galaxy S II Q&A, Help & Troubleshooting] EzZn0:
I have had problems with bootloop and it was not caused by me messing around. The first time it happened I was just browsing snapchat and the phone hanged so I shut it down. The second time was when I was trying to film with the camera at the back of the phone. It freezes and when I want to take pictures with the camera through the regular app it said "camera not connected". But this time it freezed, it got stuck in a bootloop.

Now my phone is stuck in a bootloop after the phone shut down because of the battery that ran out.

This is the third time in two days I have a bootloop. I'm pretty tired on formatting the /data and then recover everything with titanium and then fix my theme so it fit my liking.

I haven't done anything with my ROM or kernal in maybe 3-4 month. My ROM is ReVolt v 4.3.

EDIT: My bootloop problem seems to connect to snapchat. It pretty weird since I haven't updated snapchat for a while now and it has worked fine until 2 days ago. I am having my 4th bootloop on 2 days as I am writing this. I have searched about this issue but I haven't found anything.. I have however updated xprivacy and I have restricted snapchat with it. It may have something to do with it.

i dont even have a rom. and i cant get to cwm to wipe and start again. i cant odin via the computer because 3 laptops wont recognize it (i belive you need it to be turned on and in a rom to install the drivers correctly) so i am stuffed that way too... maybe its just a paperweight now?!

Debugging don't matter mate. Have you tried a different PC. Read [MENTION=4851213]Hopper8[/MENTION] thread about failed Odin flash. Great info on there.

Not sure ive lost count of the amount of threads ive read and things ive tried tbh. most of my problem is the pc wont connect to it in any way but other sgs2's work and other phones as well so cant be the cable its either this end or the phone... If i could get the lappy to see it then i would be sound!

i had problems with siyah kernel i think is the route cause of it after of the reading ive done but it wont matter when i get the neat rom because i will reflash a kernel anyway even if its stock.

re-re opening an old thread

This is in main lines the same issue I have. Hours of googling and searching this forum. Now i found this thread, im re-re opening it. In my case im not stuck with the screen with the yellow triangle, but it keeps rebooting till that part and than turns black for a few sec and then again this written Samsung GT-I9100 with the yellow triangle.

My History before this:

Rooted phone. Installed jeboo_kerne_i9100_V1-2a

CWM-KitkatCompatible-i9100 from galaxys2root.com

Wiped userdata/wiped dalvik/wiped partition

installed zip: Omni-4.4.2-20140213-i9100-NIGHTLY (considered stable)

installed zip: pa-gapps-modular-mini-4.4.2-20131215

wiped dalvik

accidentally rebooted to bootloader. Saw the message NOT to turn off phone.

Chose to turn off phone anyway (since I dont wanted to bootload)

Turned phone on and got stuck after hours where I'm now.

Most logical solution that has been found on "the netz" is: Broken power button.

When i remove the battery, put it back. Phone stays off. Volume up/menu/power button, it goes to status as described above. (Same with volume down/... or just the power button)

Any solution? I created an account here, just for this atm.
[Galaxy S II Q&A, Help & Troubleshooting] Appie_nl:
In addition to above:

I do get in download mode! On another forum, someone told me:

But the phone on an usb-cabel and press "Home/ volume down". The phone is able to enter download mode. I could use odin in this case.

Remarkably, the phone stays on! So most likely, no hardware error with the power button!

I really like to hear someones opinion or solution.

23:05: SOLVED! Finally after getting in download mode, reflashed clockware 6.0.4.5. After flashing this, tried again to get into recovery mode. SUCCEEDED! Wiped all data again, reinstalled stable CM 10.1.3. Rebooted: Booted!

Hi guys

I'm new here so I hope you can help me.

I have Samsung galaxy S2,not rooted with original firmware 4.1.2.

I never had problems like this.Yesterday I was on my phone using Facebook application on WI-FI.After a while my phone restarted by it self and it was frozen with SAMSUNG GALAXY S II logo.I waited but it restarted by it self again and again it was stuck with the logo.It couldn't start up the phone.I took out the battery few times,started the phone and again the same problem.Only once after a some time of waiting and pressing the Power and Meny buttons together I think it started the phone and got only to other SAMSUNG logo,and the it restarted again by it self.I pressed the POWER Button and the menu button together,but nothing happened.After few other tries of restarting,battery taking out.......another problem. The phone can't start at all now.I can't even get the SAMSUNG GALAXY S2 LOGO.The display is BLACK now,nothing happens.

I was reading on internet today that this is called BOOT LOOP,and I can fix it by pressing all of the three buttons at the same time and then do a FACTORY or MASTER RESET...........BUT THE PROBLEM IS THAT I CAN'T START THE PHONE AT ALL TO GET TO THAT POINT WHERE I CAN DO A FACTORY RESET!!!!

I took my phone to some repair shop and they told me that the battery is OK,and that maybe the problem is BOOTING or the Processor.

PLEASE HELP ME TO START THE PHONE UP,SO THAT I CAN DO A FACTORY RESET or if there is some other solution !!!!!

Thank you in advance

Help

It all started when the phone was low in battery, and when I tried to turn it on again, I was stuck in the (black and white) samsung logo. I can't access recovery mode, but I can access download mode. I never rooted or flashed anything on the phone. It was completely stock.

I tried searching for my stock firmware, but ain't sure which one is it since the carrier doesn't appear on the list. All I know it's that it starts with I9100UHXXX. The country is Panama and the carrier is Digicel. I went with the unbranded firmware that I found for my country.

Odin recognized the phone, but once I tried flashing the firmware, it failed.

I also tried flashing Philz, and Siyah kernels. It also failed.

I've tried to flash it several times, from all the usb ports in my computer, and using different usb cables. Failed each time.

I think I hit a wall or something. Any other suggestion besides flashing the pit files?

I'm also trying not to lose the info I have on the internal memory (music, photos specifically) that I couldn't back up in the memory card, so if I can do that,it would be awesome.

Thanks in advance.

Yellow triangle after flashing CWM recovery

Edit: Solved, found stock ROM from SamMobile and installed it with Odin.

Another one with the yellow triangle here. I was trying to get to CM11 from stock ROM. Here's what I did:

Rooted phone according to this: Steps: Rooting GT-i9100 4.1.2

Now it seems this was an unnecessary step, but this was something I did before I even looked at any instructions on flashing a custom ROM. At least now I have Helium backups of all the apps and all.

Installed CWM Recovery according to this: ClockworkMod (CWM) Recovery for Samsung Galaxy S2 GT-I9100 (Android 4.4 KitKat Compatible!)

The comments section shows that other people have faced the same problem following these instructions. I followed the latest commenter's advice and continued with the instructions, ie. booted to recovery and installed CWM 6.0.4.5.

Recovery works fine, but as the commenter says, Android won't boot, it just shows the yellow triangle.

I made a (NANDroid?) backup from the recovery and wiped data, cache and dalvik. As the commenter instructs, I should now install a custom ROM, since the stock one doesn't seem to work with this version of CWM, am I right? The problem is I did not anticipate a booting problem before I went and flashed CWM, so I don't have any ROM or gapps packages on my phone to install from.

I tried to push the packages via ADB, but although it seems like they transfer successfully, I don't see them in the recovey. Now I understand it's because I had disabled USB debugging before all of this. I used my older phone to download a CM11 package onto the SD card, but when I tried to install it on the i9100, it says it's bad. I would have tried a couple of other packages but I kept getting download failures. The phone is incredibly slow and a real drag to work with, so I gave up with that.

I'm guessing Heimdall would be the answer here, but since I am new with all of this, I would like to proceed very carefully from here. So what would be your suggestions? I have all my important files on my computer and/or in a cloud so I don't mind wiping everything on the phone. I still want to get CM11 but any working phone would be nice.
[Galaxy S II Q&A, Help & Troubleshooting] Dark Madder:
thanks but

I only added a few basic mods, but tired & nodding one night I tangled two codes and ended up in the loop. Great to discover the 3 button press options; however I've been out of the tech for so long that apparently when, for e.g. the Xposed Installer states "a backup has been created for you", during install, I ACTUALLY believed that a backup ACTUALLY HAD been created. So now I'm told that I must flash a new Rom 'cause I effed a mod to let me turn the screen darker without turning it off!? All the apps & mods I added through .Xposed are history until I can start pulling threads. So if one neglects to implement say -Titanium Backup or the like in this circumstance, where the heck does that alleged backup go? It is nowhere to be found on my sd which was the place I expected to find it. SO fun catching up.
