New version – improved performance, stability and browser for PRS–950

We spent last month working on optimizations and stability of the firmware. Also great news for PRS-950 users — we have a browser  for them.

Enjoy and give us your feedback.

Download installers from here:


  1. Trying it right now.
    Is it ok to instal over RS+ fw?
    Thanks, guys! Keep it up!

  2. I like it !
    Definitely an improvement from an earlier version.
    You guys are doing terrific job for us, the Sony users.
    I got the firmware on both of my PRS 350 and 950.
    Please, do not stop making further progress.
    I am glad that you as Russians provide such contribution
    to the whole world in this positive way.
    Thank you !

  7. Tried that, did not work. Even tried to open the device and disconnect the battery as “reset” button wouldn’t work.
    After various attempt it booted with the original firmware.
    Any idea?

  8. Excellent update, seems more stable than the previous one. Keep up the good job !

    Comment by Axel — March 11, 2012 @ 4:23 pm

  9. After a few days of testing I still like the update very much – excellent firmware ! One question: it seems as if EPUB with images included are not fully supported – at least I cannot see the images. Is this a known issue ?

  10. Is it possible with this new browser to download a .pdf file? Or at least open a pdf file?
    For example, opening this page:

  12. благодарю!
    в отличии от других прошивок, эта ставится моментально.
    из плюсов- совсем другой аппарат получился, удобнее!
    жать надо на книгу 2 раза (а раньше случайно коснёшься и жди загрузку, бесило прям), теперь список по папкам, удобнее гораздо. игры только со стилусом (пальцами кривят почему-то)
    открывает все форматы из интернет библиотек (FB2, RTF, PDF)
    из меню убрано лишнее.
    из минусов- картинки не ставятся на заставку, предпросмотра нет (мелкими рисунками), те книги, что программами конвертировал- отображает на татарском какbм-то, формат LRF не открывает.
    ОГРОМНОЕ СПАСИБО разработчикам. реально 950 книжка стала другой

  13. Благодарю за проделанную работу.
    У меня PRS-350, все работает хорошо, кроме чтения HTML, файл открывает и показывает пустую страницу. Все остальные форматы читает на отлично.

  15. I have a prs350 and installed this software but I no longer have access to notes/drawings which i used a lot. How do I go back to the sony firmware?

    Comment by trina — April 11, 2012 @ 1:19 pm

  16. Hi all,
    I see here a lot of problem solved.
    I’m an prs950 user and I have a lot of problems with Romanian characters because I have to do a lot of things to see it and I can’t use the RTF files because prs 950 can’t recognize Romanian characters. Can this upgrade solve my problem? Thank you and wait for youer answer! Have a nice day!

  17. after update my prs-650, my computer don’t recognize driver. moreover, i just read book and don’t do anything more such as listening music, take note… I want to come back original firmware, please help me…

  18. Благодарю разработчиков за Новую версию для PRS-950!
    Загрузил поверх прошивки ver. amutin.
    После загрузки вашей прошивки вставил SD карту, поставил ридер на зарядку, после отключения от зарядки на экране ридера появилась информация с SD карты в прошивке ver. amutin. Я перезагрузил ридер – он включился уже в вашей прошивке. После подключения ридера по USB к ПК ридер загружается в версии, но после отключения от ПК ридер переходит на карту SD, и информация отражается в прошивке ver. amutin. Для того чтобы перейти на вашу версию, ридер надо перезагрузить. Скажите, как устранить проблему, чтобы ридер всегда работал с SD картой в вашей прошивке?

    I very want update your firmware but i can’t do it for my device.

  20. Проблема: уже дважды SD карта (32gb Transcend) невосстановимо портилась (RAW формат). Могла ли прошивка вмешиваться в SD на какой-либо стадии работы или при зависании книги? – После зарядки и последующего отключения от USB книга загружается в старой прошивке и индексирует новые файлы на SD. После этого, при выключении книги она иногда зависает – но работа карты нарушалась не сразу после этого.

    Comment by Alexey — June 3, 2012 @ 6:10 pm

  21. А формат LRF поддерживает прошивка?

    Comment by Jaid — June 21, 2012 @ 11:59 am

  27. Скажите, пожалуйста, как подменить файл wallpaper.png чтобы книжка радовала глаз и в выключеном состоянии?

    Comment by Александр — November 6, 2012 @ 2:18 am

  28. О_О Догадался сам, просто кидайте в корень файл с таким названием, желательно поменьше размером.

    Comment by Александр — November 6, 2012 @ 2:37 am

  29. This version has been the most stable so far for my prs-350. The only bug I’ve noticed is that while in landscape mode it’s impossible to change to a different font. If anyone could fix this it would be greatly appreciated!

    Comment by arnoldo — November 21, 2012 @ 8:34 pm

  30. Прошивка понравилась, встала поверх официальной с “Бородой” (вер.1.05n). Большая библиотека с lrf оказалась бесполезной, но открылись другие возможности (fb2, zip и т.д.).

    Может как вариант сделать загрузку с выбором “оси” – оригинальной и альтернативной. Или всё-таки “прикрутить” lrf.

    Cпасибо за прошивку!

    Comment by igor — November 25, 2012 @ 10:27 am

  31. How do you change the Brightness and Contrast when you are reading a pdf. This option has disappeared from the original version. Very nice job otherwise. Thank you

    Comment by Toni — January 25, 2013 @ 9:03 am

  32. Tried it on prs-650, it works great except that there is no boot menu option of the new ebook applications or return back to sony). Can we put back that firmware selection menu at bootup?

    Comment by joe — January 29, 2013 @ 3:41 am

  33. Can I use this version for Sony PRS-505? Please answers me !

    Comment by Misojogi — January 30, 2013 @ 10:13 pm

  34. некорректное отображение зарядки, может полностью заряженую книгу показывать разряд батареи, лечится хардперезагрузкой. согласитель каждый раз после зарядки делать хард ресет не очень приятно. и переодически включается сама. прошивка 809S sony 350

    Comment by Алксендр — June 26, 2013 @ 11:56 am

  35. I was tempted to try this firmware, it looks interesting, I use to prsplus, but they were hanging upon the development of a better firmware

    Comment by coco — October 8, 2013 @ 7:34 pm

  36. sin duda el cambio frente a la anterior versión es sorprendente, lo que quisiera saber bien es como cambiar o adicionar mas diccionarios, pero por lo demás quedo sin palabras, es un extraordinario trabajo, para mas detalles del diccionario uso un prs950

    certainly change over the previous version is amazing, I wonder what it is like to change or add more dictionaries, but otherwise left without words, is an extraordinary work, so I use a PRS950 details

    Comment by diego — October 12, 2013 @ 1:08 am

  37. Thanks for creating this alternative sony ebook firmware.
    Just installed it on my prs-650 and i enjoy using it.
    Looking forward to newer versions.
    Many thanks to the entire team.

    Comment by Marnix — October 20, 2013 @ 4:57 pm

  38. firmware operation is excellent, simple and easy, but the only drawback is observed epub format styles as it does not exist and is just a lot of text, so the rest of other features implemented and progress with respect to the previous development is impressive.

    el funcionamiento del firmware es excelente, sencillo y fácil, pero el único punto en contra observado es los estilos del formato epub, ya que no existen y se ve solo un monton de texto, por lo demas el resto de caracteristicas implementadas y el avance con respecto al desarrollo anterior es impresionante.

    Comment by diego — November 21, 2013 @ 6:01 pm

  39. Hi!
    I use PRS 950,
    Instaler can’t detect my book (either with patches or even after I deleted them). I turn the reader off before launching the installer.
    Perhaps I could download an older version of your firmware first?
    Thank you.
