Another question about going from KK to JB

So for example, let's say I was currently was on M9 Pro RileyROM 2.6b KitKat and wanted to try M9 Pro RileyROM 2.5.2 JB.

The steps would be:

1) Run the 1.37 Flash Tool from the RileyROM 2.6b download
2) Click "Erase NAND"...wait for it to finish and then exit the KitKat 1.37 Flash Tool.
3) Run the 1.37 Flash Tool from the RileyROM 2.5.2 JB download
4) Don't "Erase NAND", but check/add the "Loader" option and then click "Flash ROM".

Is that the correct steps?

Sorry if I'm being a little redundant here, but I've read that you needed to change the "Loader" in the original post, but that really hadn't been mentioned much since.

Thanks!

Re: IMPORTANT: Switching back to Jellybean from KitKat

In my opinion these are the steps you've to follow:
1) Run the flash tool on the 4.4.2 ROM (KitKat)
2) Erase NAND.
3) Close the "KitKat" Flash Tool and now run the RK-Batch Tool to flash the Stock-ROM from *.img file.
4) Select the FW path and just flash by using the "Restore" button.

OK thanks. Thanks very much

To update from JB to kitkat there is no need to do it, is only when you downgrade from kitkat to JB.

If you have JB and you want to upgrade to kitkat you can use the normal procedure.
If you have kitkat and you want to downgrade to JB then you need to open kitkat flash probram, rease idb and then open the program to flash JB.

ok ... thanks.

When we flash RR 1.8 (from RR 1.6) do we have to erase the NAND with the flash tool and parameter file from the 1.6 rom first? ... and then flash the kit kat rom?

OK I understand the process but if I want to go back from Riley rom kk2.6 to stock rom ( PiPO M9pro_software_OTA_3G&wifi_chinese&english_2014-03-06.) that is only a img file, what's are the steps I've got to follow?

Sorry to ask, but will that info also work on Minix x7? Read about some ppl that do have alot of problems switch between kk and jb there..

Didnt try my self, but now i maybe will! :-)
Just dont need to brick my device..

Excellent explanation. Thank you for the effort.

[rrileypm]

That's correct. It's just easier to explain...and do...if you just run the flash tool for each of the involved ROM kits. The parameter file loads when you start the tool, so just run the KitKat tool first...then run the Jellybean tool. It's the same tool, just different parameter settings.

[uli-hh]

Thanks for your explanation Randy.
But let me verify if I understand right. The flash tool will be the "ROM_Flash_Tool_137.exe" in both times.
But the difference are the different parameters in the "config.cfg" file. Right??
