Stucking at Google logo.

hi everyone !
i just bought Nexus S and follow online instruction to unlock the bootloader and root the device. So far evrything going so well until i do " flash rootboot.img" (download from nexushack.com) and my phone is stucking at google logo forever.
Then i try to "flash clockworkmod recovery " is successful but my phone still be bricked. Have try to return to stock GJH-78 BUT STILL NOT WORK.
Can anyone help me to bring back to live my phone, thank you.
My phone is G-i9020.

i found that ODIN was the best way to get my phone back from being bricked.
The rootboot at nexushacks also did that to my phone so dont use it.

I think the problem is that you flashed a boot image that is not compatible with your phone. First, determine if you have the I9020- A, T, or F.http://forum.xda-developers.com/showthread.php?t=1031760 You need to find a post with the stock files for your model, and extract the boot.img. Then
fastboot flash boot boot.img
(If anyone else has the exact same model as him, could you do a nandroid backup and post your boot.img?)

You may need to flash your phone via adb. That's if you can't get into clockwork, there are many threads on how to do this.

Hi, same problem here , i have the i9020A version in white.

deleted., misread.

Hello!
I'm a noob as well, but I'll try my best to help with whatever I can as I have semi bricked my phone several times and safely got away with it. Assuming you followed the instructions on the Google developer page for Android L, have you tried reverting back to KitKat with the factory images they have provided via SDK? With SDK, you can open up the terminal in the SDK tools path to send commands forcing your phone into certain modes such as fastboot that is needed to flash the factory images.

Baz, click the link in my signature. There is a step by step guide to flash back to stock.

[Completed] Galaxy S5 Active (SM-G870A) stuck in bootloop!

I don't really know why my phone is stuck in a bootloop to begin with. I've tried EVERYTHING I could possibly think of!
Here's What I've tried :
WipeData/Factory Reset and I also wiped Cache.
I tried to use ODIN to flash the original stock ROM to the device but the bootloader is locked so its impossible to flash any ROM to the devices (Even if it's official).
I tried to apply the Lollipop 5.0 update in recovery using a external SD card.
I tried using ADB sideload.
(Bonus points if you can give me away to unlock the bootloader! because i'll know what to do if it's unlocked.)
So...If anyone has suggestions, I'll happily take any!
Also Please! Leave links so I have quick access!

Hi,
I can't find a relevant thread on your device and issue, but you can ask for help here,

You can try to go through the applicable steps in this guide:
[GUIDE] UNLOCKING, DOWNGRADING TO A10, TWRP, ROOT
Hello, I'm posting this guide for those (like me) who can't do without TWRP on their device. I'm providing only a step-by-step explanation. Credits to @nikamura for his kernel and TWRP...

Like installing the USB drivers, and SDK platform tools.
Then put the phone in fastboot mode and download an image from google and do a "flash-all.bat"

it wont work , that is what caused the issue, there is no adb or fasboot commands as the phone has nothing to load or read, it was flashing the official latest stock firmware using the flash-all.bat, then after the first rebbot and waiting for devices it goes to a black screen and shows what i put in the screen shot,(i believe the battery died during flashing) there is two modes it goes into the qusb which is the qualcomm download mode and some other mode i cant tell neither can the pc device find drivers to read the phone, techinically this phone is not fixable using normal methods , but i believe there is a way to flash to firmware back on,i have looked into using edl and qspt flashing but it still doesnt read the phone, any help would be greatful i have device protection but they are sending me a refurbished phone i would rather try to fix this before i do get the replacement, as it was a new and working device

i have been able to find a working qualcomm driver is there anyway to edl or msm file for the pixel 4a to fix this, now that the phone is being read properly it should be able to take commands as it is reconized as a modem driver or port

Any Ideas Why Its Failing , says sahari protocal failed

I believe Qualcomm is the ones that obtain these files not Google , only other way is to dump the files from download mode on a working device

I'd like to help by dumping the required files, I didn't know anything about EDL before doing research for this thread, but as I understand using EDL mode require a device-specific non-free "loader".
I'm trying to use B. Kerler's EDL tool (https://github.com/bkerler/edl) but fail because it doesn't have the proper loader file in its database.
If anyone come across the loader for the Pixel 4a (000e60e10066000a_3ef72a02fb931be1_fhprg.bin), I'd be happy to share boot and memory dump from my phone.

I encountered the same situation as you, did you solve it?

Older thread I know, but I've used EDL mode (on LG phones) to save partitions and write partitions.
But you have to have a 'programmer file' for the specific device for it to work. Aka a 'firehose' file for the specific device / chip.
Some mfg's make this available, some don't. Google does not. So, even having the file(s) you want to flash won't help, not if you don't have the firehose file.
sorry, cheers

Has anyone figured this out? Could really use some help. Thank you

Only suggestions are the go to software of choice,, pixel flasher or android flash tool, both need bootloader unlocked

Right. Every apps working even on unlocked state. But would be nice to get rid of the warning while booting.

I will second that, unfortunately I don't think it's possible, at least not that IAM aware of

stuck at "checking for updates" loop

so the situation is like , I woke up and saw that my phone's home screen is freeze so, I thought of restarting it , but after I restart my phone, a "hello" screen shows(I hate it) and then I choose language then Country then Wi-Fi, then the screen shows "checking for updates" and after 2-3 minutes It automatically terminates me to the previous page and the process continues in a loop. I tried it restarting a lot of time and also tried the recovery mode but nothing changed.
My device : Realme X7 5G, 3.0UI.
I don't have a backup of my data, so I don't want to loose it, and I didn't unlocked my phone's bootloader, is there any other way, pls help me,
Please someone help me, pls

https://www.getdroidtips.com/realme-x7-rmx2175-stock-rom-file/ Is where you can find the stock firmware. because to fix this you might need to re-flash the stock firmware. and https://spflashtool.com/ is the flashing tool you'll need. follow the instructions in the getdroidtips website to flash it. EDIT: Keep in mind the files are 3 gigabytes so make sure you have enough space.
