Cross Battery problem on BlackBerry 83xx
On the BlackBerry handheld 83xx series or the other, often have problems such as cross-battery logo when plugging the usb cable to the device. whether this software or hardware problem?
This software can also be hardware problem, check the damage with the following steps :
1. if the handheld is still detected in Desktop Manager may still be solved with software flashing or by reprogramming the operating system. cause is cod files on the system load is missing or corrupt.
2. but if not detected in the DM or other tools, this means the damage is certainly a hardware problem, the battery circuit conductor paths are not normal.
steps of checking the hardware :
1. check battery, can be a simple way to switch a normal handheld battery.
2. either clean the battery connector on pcb or on battery
3. check "crystal 91HCE2" (resolder / change)
4. inductor component checks all around power-ic
5. check the "regulator 907 ps 12" (resolder / change)
for step 3,4,5 please look at the scheme.
If the above steps have been conducted, but cross-battery problem persists, then it entered the advanced damage, which I will discuss in the next post.

HTC M7 to be named simply HTC One
HTC is relying heavily on its upcoming HTC M7 flagship handset to return the company to former Android glories - but the latest rumour suggests the Taiwanese company may simply call the phone the HTC One.
The name change was the latest in a long line of leaks regarding the new handset and came courtesy of Twitter account @evleaks.
HTC used its "One" branding last year, culminating with the launch of the HTC One X and One X+. Two Android heavy-hitters that didnt quite land as many punches as the Samsung Galaxy S3.
The Taiwanese company isnt the most secretive tech firm out there, so even though this is just another internet rumour, there could be a shred of truth to it. After all, Peter Chou recently pulled out the handset at the companys end-of-year party in Taipei to snap a couple of pictures - and even shouted "HTC One" at the audience.
Regardless of the name, the new M7/One is expected to make its debut at Mobile World Congress later this month and will give Android fans a fresh rival to current top dog, the Sony Xperia Z.
