I just wonder why these people do this hoax.

@invaders and to motivate donations, you would need to deliver something that others could replicate.

@shahdoni XThunder is working on the EM-5 and two other hackers are working on the EM-10 Among them, a guy who has contributed to the hacked firmware for Nikon in the past. Work is progressing. Dissasembly and code analysis is underway. Long way to go still. Details will not be posted to this forum, for legal and other reasons. But I will post general updates now and then.

Hopefully, by now most people here have found out and seen through all the bull shit. those who followed Nabil and others on this forum. Some are well intentioned but full of bull shit none the less

The EM 5 successor is coming, and I'm reliably informed to expect some really cool stuff. the news will slowly leak over the next few weeks.

Can't say as I personally don't know any details, just told that some cool stuff is coming. And If I knew I wouldn't tell anyway. I love the EM 5, and like all of you hope the new one addresses some of the video spec wishlist

So the E-M5 Mark II seems to have all the video features I wanted to have on my E-M5. Could someone hack the Mark II firmware and perhaps bring some of those features to E-M5, or is anyone interested anymore?

Hi there,

I have made a set of modified firmwares for E-M1, E-M1ii, E-M5ii, E-M10ii and Pen-F. They are based on the latest official firmware versions, and in all of them the video time limitation is removed (in fact, it's just changed from 29:59 minuted to about 59 years which is enough for the most practical purposes ;) Also for the cameras with the Focus Stacking support (i.e. E-M1, E-M1ii and E-M5ii), the stacking now works with arbitrary autofocus lenses, instead of 8 Oly Pros and macro lenses.

Here are the links for the corresponding cameras with some additional comments:

• E-M1 - e-m1_v44.rar, not tested yet! Waiting for the tester's report.
• E-M1ii - e-m1ii_v21.rar, video duration limit removed for FHD and 4k video, but not for C4k; focus stacking works.
• E-M5ii - e-m5ii_v4.rar, video duration limit removed, focus stacking works.
• E-M10ii - e-m10ii_v13.rar, video duration limit removed.
• Pen-F - pen_f_v3.rar, video duration limit removed.

To install the firmware, you'll need to:

• Make sure the battery is fully charged.
• Extract the firmware file from archive into a folder called "DCOLYMP" on your SD-Card.
• Put the SD-Card into your camera. Start the camera while holding the OK button pressed. The focus assist LED should turn on - this means the firmware is installing, and you can release the OK button.
• When the installation ends, the focus assist LED will start to blink. Now you can switch the camera off, and then on again. That's all.

It's also possible to revert to the original firmware. The files and the instructions can be found here.

The discussion and users' reports are here and here in Russian.

Some technical info in case anyone needs it.

To load a firmware in IDA, you need to specify the following values as "ROM start address" and "Loading address":

• E-M1 - 0x6DAF1020.
• E-M5ii, E-M1ii, Pen-F - 0x60021020.

Oly_fw_manip tool available from Lightsnowdev.com contains a bug preventing from correct packing the firmwares 4.4 for E-M1. The bug can easily be corrected by changing

       if (hasXmlAttrib(block, "unknown3"))
            getHexSequenceFromXmlAttrib(blkHeadUnscrambled->zeroPadding2, 6, block, "unknown3");

in OlympusFwManipMain.cxx file to

       if (hasXmlAttrib(block, "unknown3"))
            getHexSequenceFromXmlAttrib(blkHeadUnscrambled->zeroPadding3, 6, block, "unknown3");

Please bear in mind this post doesn't resurrect the Olympus firmwares hacking. I'm just sharing my findings so some more experienced researcher could continue the work.

Splits recording must be due file size reaching 4Gb.

@gietrzy In focus stacking mode, the camera always makes 8 consecutive shots. It's possible to specify number of frames in normal focus bracketing only.

I'm re-testing the video time with my E-M5ii.

Just made a FHD SF 24p movie. Had to stop at 1:59:37 because of the battery drain.

After the recharge I'm going to repeat the tests with FHD SF 60p, and then with FHD All-I.

Thanks ABel for your reply.
Anyone knows some cheap DC coupler solution for M5.II?
Later I'm gonna check if unlocked in camera focus stacking works with FT 150 macro Sigma
According to BH US model also has 29:59 minutes :( Maybe it shutdown itself like Sonys to prevent overheating? The card is nowhere hot like Sandisks from hacked GH2 :)

Fantastic work ABe1. I posted the hacking instructions on this forum six years ago and didn't expect anyone to use them anymore. You did an amazing job.

Would you be able to share some details on how you figured out the structure and content of the firmware? Others may be able to learn from that and improve things or find new hacks.

Some preliminary results of making long video with my E-M5.2.

The camera has split the long videos into smaller "chapters", the length of these chapters depends on the video quality as follows:

• For FHD All-I max chapter length is 00:07:15.935.
• FHD SF - 00:10:45.144.
• FHD F - 00:18:49.628.
• FHD N - 00:31:44.402.

And here comes an additional limitation - the camera doesn't allow for having more than 5 chapters per movie, which essentially limits the total recording time to:

• FHD All-I - 0:36:14.
• FHD SF - 0:53:49.
• FHD F - 1:34:09.
• FHD N - 2:38:49.

It's quite possible that other camera models have different max number of chapters for different video quality settings.
