I wanted to change to Cyanogenmod 10.2, so i opend CWM and formated, wiped cache and dalvik cache. Then I installed Cyanogenmod 10.2 and gapps, but the phone came to the samsung logo and kept rebooting, I couldn't open the recovery. So I opened download mode and I installed the stock rom for my country (Croatia), but the phone was again just rebboting, so I installed CWM but I couldn't open it. I tryied to do the same thing with a different version of the stock rom, but it ended up the same, so I even tryied with a Serbian version but it was still just rebooting. Please help me, I can't figure out how to fix my phone.
Hi,
You have to wipe /data partition from CWM when switching to a new rom. This prevents you from having bootloops.

1. Powered off the phone.
2. Press & hold Volume up + Volume down + Home then power on the phone.
3. Wait a few seconds until recovery mode appears
4. Release all buttons.

I do all of that, hold volume up + volume down + home and power, but nothing happens.
Can I open recovery mode in any different way?

Hi all,
My Nexus 5was running stock Android M till last week and I wanted Android N. So I rooted my phone installed TWRp and loaded android N by @santhosh. Everything went well but at times some apps kept crashing including TWRP. So I decided to to do a clean wipe. I did a clean wipe from recovery but after that my phone is not booting up. It's stuck on bootloop.
I am not able to boot into recovery mode also is there any way to save my phone?
Pardon my English.
Are you able to access the bootloader (hold power button + vol down until the phone boots)
I suggest using NRT to flash a stock ROM.

No i can't. It will go to bootloader When I press volume down + power but only for a second or so.. After that it'll bootloop.

Sounds like a dead power button?
Not sure, never had this problem.
But that is a common issue
The fact that the phone is not detected by the phone makes it difficult to re-flash a stock ROM.
If it is a power button issue, I recommend removing the motherboard, cleaning around the power button with pure isopropyl alcohol., quickly press and release the power button using a bit more pressure that usual, replace the motherboard, and try again.
Hi,
After 2 days of research, I permit to ask your help. Since replacing my SIM tray soldering on the motherboard of my OPO, I can't boot my OPO normaly.
Just the recovery (TWRP) boot, I can "install", "restore" what I want, but after installing anything change, My OPO reboot into Recovery each time !
Maybe my OPO is briked ? Maybe is it possible to re install Fastboot if it's lost ? Can you help me please.
Thanks in advance for your help !

Sorry, no I can’t access into fastboot too
Maybe I supposed the Vol- vol+ button will be broken, but it seems good... For test, I can’t navigate in TWRP with vol- vol+ button but maybe is normal in 3.0.0 version, please can anyone test and say me is it same ?

Nope,those buttons doesn't work in twrp.
Open up your back cover and clean it(isopropyl alcohol would be awesome).Also,clean volume button strips a bit.At last, make sure you fit back cover correctly.
Thanks, I will clean this afternoon and tell you if resolve the problem

Did you clean the volume strips as well?
Yes, I’ve cleaned the back of the strip volume button, and test with the strip straight without the curve, and it is same problem...
Hi,
My problem persist, I can't boot in fastboot mode, maybe the fastboot partition is lost ? How can know it ? If is the case, How can I repair the partition please ?
Thanks in advance for your response.
Did you try rebooting to fastboot from either the TWRP menu or from your ROM?
Yes I tried, but it reboot in TWRP, no fastboot mode
Delete
Ok, but delete what and how ?

No this toolkit does not run in fastboot mode what you need to do is power off the device and hold volume up and power and plug in your usb cable the screen should be black and then in device manager you should have a option called ports or if the driver for the qualccom port is not installed it should come up and right click the driver that is not installed and select find driver online once that is done click ms 9. Exe and run it as admin

Hey,
I have the same problem with the bootloop and the corrupted locking screen. I'm able to boot into download mode, but I can't figure out which system to flash. I tried several ones, but none of them worked... and I can't get back to the factory recovery. If somebody has an idea which recovery system could work I would be very pleased to know.
Software used to Flash: Odin
Device: a750fnxxu4ctc4
