First of all, let me say that I appreciate all the work everyone has done on the Infuse forums. It has expanded my knowledge by leaps and bounds just by reading for about 5 hours today. I know this will be a long post, and I apologize. I am just trying to show that I have done everything (so far) that is within my ability to try.
I inherited a "mostly working" (sound doesn't work at all) AT&T Infuse 4G, and am trying to install CWM and root the bugger in order to use it on WiFi as a mini tablet. I Do Not have a SIM card for it (I am on SIMple Mobile, not AT&T), and do not plan to use it for calls (already have a phone for that). It was already running UCLB3, but I wasn't sure if that was how the phone came, or if it had been upgraded from Froyo at some point with or without the bootloaders. I had planned to play with this phone some and maybe try out some Jelly Bean since my T-Mobile G2x has lost most of the wonderful devs that it had.
First, I used the Settings>Privacy>Factory Data Reset to clear all the information on my phone and my internal SD card. I made sure that Java was the latest version on my laptop and DL'd qkster's [ROM] [2.3.6] Heimdall One-click Back-To-Stock UCLB3
. I spent the next 2 hours reading and re-reading the OP and all the resulting posts to make sure I had a firm grasp on how to do everything. I first booted into stock Recovery and did another Factory Reset from there and also cleared Cache. I booted into Download mode on the Infuse 4G and ran Heimdall One-Click. Installed the Heimdall driver, closed all programs, rebooted the computer, went back into Heimdall One-Click, put the phone back into Download mode, clicked Flash, waited for phone to reboot, turned phone off, went back into Download mode and flashed again, this time with BL checked.
This entire process went off without a hitch. Phone boots into GB and all is glittery gold. It's when I come to the next step in the thread that I started having the issue. Again, from an overabundance of caution, I made sure that I read the thread again, absorbing all the information pertinent to loading the Kernels from One-Click. Deciding to try InfuZen-A16 Kernel
, I downloaded it and ran it just as I had the previous One-Click. Opened the .jar, booted the phone to Download mode, clicked Flash, and let the phone reboot. Uh oh. Samsung splash screen is staying on my screen now...
Maybe it just needs a while to process. Left the phone plugged in so it wouldn't lose too much battery life and went and did some more reading on the forums. 5 minutes, still Samsung screen. 10 minutes, still Samsung... No biggie, I'll just read some more. Maybe this is just a longer process than I thought. 30 minutes later, still Samsung. Okay, something must be wrong... Hold down power button to shut it off. 3 minutes holding button, still on. Battery pull...
3-button workout for recovery... Nope, no such luck, still showing the persistent Samsung screen. Back to Heimdall One-Click for recovery to UCBL3. That works. Back into stock
recovery. Again, Factory Reset, clear Cache. Download mode, try again. Flash InfuZen-A16 Kernel a couple more times (flashing back to Stock between attempts), using a different USB cable and different USB ports, but still same thing each time, leaving the phone for at least 15 minutes on the Samsung splash screen to see if it moves anywhere. I then tried the ENTROPY512's 4.4.2012 kernel
, hoping for different results. Same thing. Tried it 2 more times with different cables and different ports. Each time that I flashed back to Stock, it worked on each USB port and cable I was trying, so I don't "think" it could be the cables or the ports that are causing the issue.
Any help is greatly appreciated. It is my understanding that to get root on UCLB3 and above, I need to have CWM installed, but other than Heimdall One-Click Kernels, the only way to get CWM on a phone is by having it already Rooted. If I am erroneous in this understanding, please point it out and I will happily do my due diligence to fix my own problem.
Thanks in advance for any help anyone gives me.
