Don't install anything that is not meant for s7562c!!!

Au revoir

I'm afraid KlinkOnE is correct.

I have a GT- S7562C and I've tried to install a custom rom through CWM and hard bricked my GT-S7562C. So do not do it.

What you can do if you have a JTAG, you can repartition the EMMC using a GT-S7562 dump. After you've repartitioned the EMMC, you'll be able to install GT-S7562 custom roms. That's how I got my GT-S7562C working with GT-S7562 roms. I currently have PMP Kings rom with both sim cards working. So, after the partition, there shouldn't be any issues, however, I wasn't able to install the latest 4.4.4 Rom for the GT-S7562M yet. I'll keep you guys updated if I can get it to work.

I'm certain there are other ways to repartition your EMMC, however, I definitely don't recommend it.

If you look at the PIT files of both devices(S7562 and S7562C), you'll see that they have different partitions names and different flash file names and therefore cannot be cross flashed until you've set correct partitions.

Good luck!

Thats very interesting thanks for the info! I thought the C has another chipset.

S7562C has broadcom chipset
S7562 has qualcomm chipset

i cant imagine how it could be possible that cross flashing is working.

Ive downloaded the s7562c kernel source from Samsung osrc. It is for broadcom chipset. This cannot work on qualcomm and vice versa. For the s7562c there is JB available so why pmp?

I found nothing about s7562c device like yours.

Actually, when I initially flashed it, I didn't see the S7562_C on the pcb. I was thinking, eh, what the heck, I have CWM Recovery so what could go wrong. Soon after the flash, the phone said something wrong with the boot (Dead boot) and then it just didn't start. Hard brick, as there were no power. I then JTAG'd it and since the JTAG I used didn't have the dump for the specific S7562C, I used the S7562 dump. It reformatted the EMMC just fine.

Here's the log:

All Done.

After it was finished, I got it to boot to download mode, and I kept trying to load the original S7562_C firmware (JB) like you've mentioned. I kept getting (0x30) not initialized or something like that and I did a little research on the PIT file to see why I wasn't able to, and that's when I realized that the partitions were totally different. After that, I flashed the phone with the S7562 Firmware and bam! started up this bad boy. Then after that, I was like, eh, what the heck, lets do one better and flash a custom rom.

Now I have a working S7562_C with S7562 custom rom.

Here are some images of the phone. (Stored on pcloud, so you may have to sign up, sorry)

Maybe with this information, we can compile a JB custom rom using GT-S7562_C firmware on the GT-S7562
