Useful info. I have all this stuff but never tried soldering for resurrect only pre-made breadboards which didn't work for me but perhaps I get my thinking cap on and learn properly now!!!

Purchasing RIFF v2 - JTAG Manager

Howdy 'yall!

I'm looking to buy a RIFF box, as I accidentally washed my Samsung Galaxy S4 (SGH-M919 TMobile). My question is, when I purchase the RIFF, can I download / activate all software once I buy the RIFF? Or is it sold separately? Here's the 2 RIFF I'm planning on getting one of them, most likely the first

Also, the mainboard on my S4 may be bad, so I may need to replace it. I'm wary of EBAY as it's so easy to sell one "AS IS" with a bad IMEI (lost, etc...) shady dealers replacing the mainboard and selling the lost phone, selling me an unusable part - BUT

If I have the RIFF v2, can I change the IMEI of the new (used) board to my IMEI? I realize that this could be 'frowned upon', but I don't think it's a problem since it is my own IMEI. If my board is DEAD dead, and I can't extract the IMEI from my old phone, can I simply type it from the sticker on my phone or will I have to dump some kind of Asynchronous encrypted certificate for T-Mobile to register it?

Sorry for all the questions, it's my first post. As an electronics engineer I like an S4 I fixed more than an S7 I have to pay $700 for.

I will try to answer to the best of my knowledge.

1) if you washed your s4 ( fell in water) then your phone has hardware damage not fixable with any jtag box... Jtag can only fix corrupted bootloaders... That happened after a bad /wrong flash.... Or bad kernel /modem /custom recovery flash etc.

2) yes... It's still a good idea to own a riff box 2.... However make sure you buy it from an authorized vendor. Look in the forum to find the authorized vendor list. Yes... Once you have the riff box 2 you can download all the files you need from the server with no limit.

3) it's always a gamble when you purchase a motherboard from ebay... Contact the seller / you are buying at your own risk.
No... Riff box does not repair IMEI... It's mainly a Jtag /Emmc /ISP tool.

Start with lots of reading... Read the riff faq and questions and answers.... There's a lot to learn if you are new.

Have fun!

RIFF Box

Is the RIFF the most capable, in terms of what it can do to repair Samsung Galaxy models? So far I see RIFF is the best, but there are others such as ORT, Medusa, and Z3X. I see that there are adapters for the RIFF to Medusa, etc.

If I can't fix my S4, I want to get a hard-bricked S7 for a reasonable price, repair and unlock it and use it on T-Mobile. I've repaired other things such as WiFi routers with homemade and JTAG adapter, but I'm a newbie when it comes to mobile phone repair.

Agreed, the board is most likely FUBAHAR (all hope of repair).

You will have to read.... Gain knowledge and know what tool is best for you. Knowledge / experience comes first..... For example you said you wanted to find a bricked S7 then jtag and fix it....etc, If you had knowledge you would know that the S7 has UFI memory and not Emmc.... There are no tools at this time that can read/write UFI memory.... So corrupted bootloaders cannot be repaired by any box at this time... So buying a bricked S7 is a very bad idea

tools to be used

as it is about microsoldering I reccomend using a good microscope

The best are 3D stereo microscopes, but their are very expensive.

Very good tips. Now just need to understand about the Riff interfaces (JTAG and RJ45), any hint of study ??

Nice Info ! Thx a lot

thanks...for good info

thanx for info

Спасибо большое за подробную информацию.
