if your having trouble with your xolo/osd i.e stuck in bootloop e.t.c then try this:
(this is presuming you have ricky's aio tool intstalled)
Here's what to do:
1.open windows task manager by pressing ctrl-alt&del and click on the processes tab and end the ADB process.
2.now copy c:/sandiego/xolo/update.zip to c:/sandiego/tools
3.boot phone into fastboot and connect it to pc
4.go to c:/sandiego hold down shift and right mouse click on the tools folder and choose "open command windows here"
5.type: fastboot -i 0x8087 devices (to make sure the device is connected)
6.type: fastboot -i 0x8087 erase cache (wait till its finished)
7.type: fastboot -i 0x8087 flash update update.zip (now it will flash the update)
Did exactly told. No hickups in the process. All the commands got executed perfectly. But in recovery mode on the phone it displayed,
"E: Verification failed
Looks like a problem with update.zip, no?
How I ended up here?
My Xolo X900 was not rooted. On stock rom 4.0.4. Suddenly my wifi refused to turn on, so I factory reset the phone. Since then it gets stuck in boot loop. Shows different colors on every automatic re-boot(Red, green etc.)
I have read all the topics on fixing this brick but none has worked. Please help me in troubleshooting the problem.
