[Q] Need help galaxy s2 i9100 boot loop and freezing

Hello I am searching for help. The problem is that my galaxy s2 i9100 stopped working properly. It started like this maybe I took out the battery or something I don't remember and then I turned it on the phone wouldn't boot. I thought maybe my android operation system got bricked so I decided to re flash it but as I can remember the phone wouldn't go in to download mode but some how I managed to reflash the firmware but then phone booted it just froze and then I pressed lock button the phone screen would go black and reboot. After installing cyanogen mode 11 the phone would boot and it could be used again until pressed the lock button it would go black and reboot so I have been reading forums and found problems like boot loop corrupted mmc or something else corrupted and I don't know what the real problem is because the symptoms are like boot loop or corrupted mmc or soft brick. I have already tried other kernels other android versions clock work mode

I have found that my emmc has the insane chip bug. The phone boots normally with cyanogen mode 11 but then it goes to sleep mode or I press the power button the screen goes black and the phone restarts. I have tried siyah kernel to try dual boot but then I flash siyah I cant get into recovery.

I think you should flash latest STOCK ROM with Odin, and then follow available custom rom instructions on xda...
Test if the stock rom will work for you, boot your phone etc... Try to use it a few days. If everything is OK, proceed with
further procedures...

I have already tried this but with the stock rom phone boots but at the section where I have to chose language I jus freezes stops working

So I think it is a hardware problem. Phone on stock rom shouldn't freeze on language selection. Something is wrong. If you are on warranty, let them fix it for you, if you are not, try to fix it in some phone repair point. I'm sure you can stop your attempts. It will not be better for now.

[Q] Someone please assist me : )

I cannot get a ROM to stick, after one reboot it gets stuck on the boot logo. I have looked through all of the forums and have done this step by step. I have an unlocked bootloader. RSD lite back to stock with success, then root, then install latest TWRP. Nandroid backup then format data, then install ROM. When I reboot it gets stuck on boot logo. This happened ever since I installed CM 10.2, but I really want to install another ROM. I am not sure there is anything else I can do. Can anyone help me?

Nevermind, all is well, the first boot just took 15 minutes or so, which seems a bit long but fixed nevertheless.

There's a fsck (disk check) process that runs and sometimes takes quite a long time. Many have had this issue, patience is a virtue. So are proper thread titles...

[Q] Asus TF300T boot loop CM11/OMNIROM logos

(backstory) Hi, ive had an Asus TF300T, for about 3 years now, unlocked, rooted it pretty early on... cycled between cyanogenmod and omnirom quite a bit, without really any major issues. Until today, i was running Cyanogenmods latest nightly build (CM11 Nov 5 2014), it worked just as any other nightly does a few bugs here and there, but nothing major and i hadn't done any major flashing or modding to the device. On my home from university, I turned my tablet off. And when i got home i plugged in the charger, and just as always the tablet turned on, showed the stock Asus screen, then changed to the Android boot animation... the animation then suddenly froze, and the device went into a boot loop... continuously... I dont know whats weong with it... tried to do a factory reset, i tried reinstalling the ROM, tried installing omnirom, but that got stuck on the OmniRom animation...
Im running Asus build 10.6.1.27.5
I had TWRP v2.7.0.1 installed but have now no longer works
id really hope there is a solution for this!
Thanks!
Edit: I dont know why, but when i try using fastboot or adb, the device isnt recognized. It doesnt show up on device manager either. I dont know if its the cable cause i bought it new, it says its can sync data, or a faulty charge/sync port....

Im running Asus build 10.6.1.27.1 (I know that theres a newer version 10.6.1.27.5, but when i try to flash it, the recovery says error and fails)

^THIS!
I was just to open a similar thread, then i saw your post. I join your request for help!
A month ago i have done a favor to a friend by unlocking his tf300t and installing CM11 on it. A few days ago he comes to me with this problem. I've tried anything but still no success:
- restore a backup done before flashing CM11 --> restore ends correctly but the problem remains
- flash a rom (CM11 and OmniRom) --> flash ends correctly but the problem remains
- flash the stock firmware found on asus website (WW_epad-user-10.6.1.27.5.zip, the SKU is correct for my version) --> the flash process stuck (i had to force restart the tablet after almost 2 hours of "flashing")
Since the boot animation changes according to the rom, i suppose the flashing process works. But the problem remains: after a few seconds the animation freeze and the device restarts, in loop.
Informations on the system:
- build 10.6.1.27.5
- TWRP v2.7.0.1 (working!)
- adb works (i managed to set /data as rw and push the .zip file to flash)
- fastboot should work
Please help! I feel a bit responsible for bricking my friend's device

SOLVED!
Finally!
I had already tried this method, before requesting for help, but the first time didn't worked... I don't know why this evening the tablet decided to collaborate:

That worked for me! :victory:

[Q] I have problems with updating lollipop 5.0 in my Nexus 4.

So, my phone was stuck in No Command bootloop. I’ve done the power+volume up and had cleared cache and even done a factory reset. Those did nothing and my phone is still in stuck No Command loop. I think I’ve made it even worse by trying to Flash Recovery and Reboot options in the Nexus Tool Kit because my phone won’t even get to the No Command screen. It just turns on and turns off after Google comes on. Currently it stuck in that loop and only stops once the battery is completely drained. Also i have tried using power + volume up and it doesn't help . Please help

As you've upgraded to lollipop ?? You came from a custom rom ?? Enters the bootloader?

with wugfresh nexus root toolkit click on the button "soft-bricked"(flash stock + unroot) or something like that to restore the phone. After that try another time to unlock and root with a custom recovery (for example twrp).
When nexus root toolkit installing the original lollipop rom, look the "dos window" to see if the software shows errors, because sometimes the process ends without a real restore.
If you have other problems, please post a screenshot.

[Q] Stuck on

So I decided to try to flash Zombie-Pop today and everything went fine during installation but when the tablet started booting up it was stuck on "android is starting.." and it seems to load the apps. I knew it would take a bit of time to stabilize so I let it run but after 1 hour of it stuck there, I tried to reboot into recovery but I get a black screen and I can't access TWRP. It just boots right back to the android is starting screen. It doesn't seem to be a boot loop since it finishes the boot sequence. My biggest problem is not being able to access recovery because of the black screen which apparently is happening to some people with TWRP. I tried to go through adb but since my tablet isn't done installing, it doesn't have the drivers to run adb. Is my tablet toast? bricked?
edit: apologies for the title. I must have deleted the text before posting.

Which bootloader are you on?
How are you trying to boot to recovery?
