  14. To check if the rollback has passedsuccessfully go to Settings.

Before starting to downgrade, think 100 times, is it worth starting? Any minor mistake leads to a brick, and it is not always possible to restore it, we read the sad experience below, think - isn't it better to giverather than buying a new console or giving the client money for a killed console.
1) Reusable E3 flasher firmware (28-10-11)

SpoilerTarget "\u003e Spoiler

Method 1: through a micro-SD card.
1.download the firmware 28-10-11 and upload the update.bin file to the micro-sd card (formatted in veil 32)
2.set the switches on the flasher 1 and 2 down, the rest up

3.Insert the card into the socket of the e3-flasher and turn on the console
4.All 8 LEDs should light up - it means that the flasher has been stitched
5. You can also check by connecting the micro-SD card to the computer - there should not be an update.bin file.

Method 2: via micro-usb cable.
1.Switches are set in the same way as in the first method
2.connect the cable to the computer and turn on the set-top box
3.KernelBoot DISK should appear, if you don't press reset
4.we throw the update.bin file on it
5.At the end of the flasher firmware, 8 blue LEDs should light up

2) How to downgrade with OFW 4.83:

SpoilerTarget "\u003e Spoiler

If the official firmware is below 4.83:
If the official firmware is 4.83:
Then, respectively, we install once.
The firmware should be located at the root of the phat 32 flash drive in the following structure:
the PS3 folder, the UPDATE folder in it, and in this folder the PS3UPDAT.PUP firmware itself

1.1. We connect the flasher, switch 3 up (backup), the rest down, take the dumps 3 times, check the ros0 and ros1 values \u200b\u200bwith the inspector - they must match, that's why we just updated ofw to 4.83 (on the screen just under 4.53? But the same will be under 4.83 twice). If the dump is normal, then all readings in the status column should be green.

1.2. We check the hash sums of the 3 dumps taken with the hashtab program - they must match, be exactly the same (identical).

IMPORTANT:

If the burrow inspector program shows errors in red or the hash sums do not match, you cannot continue further in any case, you need to achieve the correct dumping, otherwise there will be a brick!If you fill in such an incorrect dump, then you won't be able to restore the PS3 !!!

1.3. Download PS3DumpChecker v1.0: Build 490 , we transfer the dump to PS3DumpChecker.exe, if an error occurs, then first open PS3DumpChecker.exe, and then drag the dump onto it.

In the loadconfiguration column everything should be green, and below it is written OK in large letters - it means that everything is in order with the dump, if it shows such a window (highlighted in the photo), then it is absolutely impossible to continue!

The program immediately prompts you to patch - we agree by clicking yes. A patcher window will appear (on the screen there is a different version, but the principle is the same).

After patching, a patched dump will appear in the program folder - bkpps3_patched.bin, perimein it in bkpps3.bin
1.4. We put the patched dump on the micro-sd card and insert it into the flasher, the switches are all down, press start and wait for the flasher's e3 LEDs to blink.
1.5. We reboot the ps3 - it should boot as usual, turn off the set-top box, then disconnect the clip from the flasher and remove it, instead we connect the hard drive to its native socket and also install the blu-ray drive - for all veils with a burrow chip, as well as for slim models 200x and 210X, the installed drive does not matter for 250x models.
1.6. Install custom firmware via xmb at least 4.83, for example 4.82.2 REBUG REX + COBRA v7.5 (you can install any custom you like).
1.7. Install via Install Package Files
multiman 04.81.02 or WebMAN or any other manager
1.8. Putting the console together.3) Instruction with dongle - suitable for any OFW

SpoilerTarget "\u003e Spoiler

1. I have already described how to take a dump in the instructions, so let's skip, we throw the native bkpps3.bin dump and the e3_downgrade.bin file to the memory card.
2. Set switches 1 - 5 down and 6 up.
3. Press Start and wait until the LEDs blink (the process is long ... wait).
4. Turn off the console.
5. Turn on the console and wait until the inscription appears - connect the controller to USB and press the PS button - turn off the console by pulling out the power cord.
6. Insert the dongle (must be flashed with downgrade firmware) into the right USB port.
7. Press the POWER button and then immediately the EJECT button - wait until the console turns off.
8. On a USB flash drive formatted in FAT32, we throw 2 files - Lv2diag.self and PS3UPDAT.PUP (Rodgero 3.7), insert it into the same port where the dongle was and turn on the console, wait about 5-6 minutes until the prefix turns off.
9. We clear the flash drive and throw in another Lv2diag.self file, wait for the console to turn itself off, it will take no more than one minute.
10. Set QA Flagging, in case of successful launch we will hear 3 sound signals.
11. Go to the network settings, but do not go, press on the joystick L1 + L2 + R1 + R2 + down on the pad + L3, it happens the first time does not come, press this combination until the menu appears.
12. In the settings, turn on debug update to ON, this is done so that the console does not bounce when installing any custom.
13. Install any custom.

4) Recovery after brick

SpoilerTarget "\u003e Spoiler

We connect two points: on the motherboard - TRISTATE, on the SBE clip loop with any thin wiring. It is also enough to simply ground the TRASTATE point - the effect will be the same.
Here are the diagrams some models of motherboards.
Advice:
When you solder the wires to the loop, you need to be extremely careful - you can easily burn the loop, the soldering iron is better to use 30 watts and solder with a light touch.


2.1. With the console turned off, put our original dump on the micro-SD memory card and insert the card into the E3 flasher.
2.2. The first switches are up, the rest are down (if TRISTATE was soldered directly to the ground, then all switches are down).
2.3. We turn on the console, the console should start, but there will be a black screen, press the start button, wait for the lights on the flasher to light up.
2.4. Turn off the set-top box, lower the first switch down, if Tristate was soldered onto the clip cable, or simply unsolder it from the board.
2.5. We turn on the console, it should boot as usual, or it will ask you to connect the joystick via a mini USB cable and insert a USB flash drive with the official firmware - we immediately install OFW, the one that was in the native dump.
2.6. If the firmware is installed then we do it starting from point 1.1. by 1.5. instructions "how to downgrade", and then MANDATORY do starting from pointand 3 - methods with RSOD firmware.

5) Method with Rogero Downgrader RSOD firmware

SpoilerTarget "\u003e Spoiler

Also, this method can be used starting from point 2. instructions on how to downgrade from ofw ..... in general, the last one at the moment.

attention:

IF THE BASIC VERSION 3.56 THEN THIS METHOD CANNOT BE USED.

3.1. Downloading the firmware3.55 Rogero Downgrader RSOD and unpack it on a phat 32 flash drive and install it in the usual way, via xmb.

What is this firmware for:

There is a chance to catch RSOD 1 out of 50 if you cast it right away
Recovering broken cells
There is practically no chance of brick
The firmware has a built-in patch against RSOD, it has all the functions as in Rogero CEX-3.55 v3.7
After installing this firmware, there will be a custom 3.55 (but it will have a syscon version of 9.99)

3.2. Downloading QA_Toggle.pkg and install it via Installpackagefiles, run it, and the screen will turn off and the HDD operation indicator will start blinking. If everything works out you will hear 2 or 3 peaks and the PS3 will go back to XMB.
3.3. Downloading

Restore or Downgrade iOS12.0 - 12.1.2 with 3utools

This article is intended for those who use devices with an A4 processor (iPhone 4, iPhone 3GS, iPod touch 4G), but want to downgrade (downgrade the firmware) to iOS 5.1.1 and get. To do this, you need firmware 5.1.1 (we remind you that Apple has already stopped signing iOS 5.1.1).

In addition, you will need the latest public version of the tool. RedSn0w... In this utility, we will use the so-called "Stitching" option, which will bind your certificate to the required firmware.

So, what steps must be taken to downgrade from iOS 6 to iOS 5.1.1:

5. Check for the SHSH certificate you saved (). If you have saved SHSH to Cydia, then just skip this step. If SHSH is saved on your computer, then place it in the same folder with iOS 5.1.1 firmware.

6. Connect the device to USB and transfer it (hold down the screen off button for 3 seconds, then, while holding the screen off button, hold down the Home button for 10 seconds; after that continue to hold the Home button, but release the screen off button).

7. Run RedSn0w 0.9.14b2, go to Extras -\u003e SHSH blobs -\u003e Stitch.

8. Select item IPSW and specify the path to firmware 5.1.1 for your device.

9. If you saved SHSH via Cydia, then in the section Blobs select item Cydia... If you have saved SHSH on your computer, then select Local and provide the path to the file.

10. Once the firmware file and SHSH are selected, RedSn0w will start glueing them together to create the final version of the firmware that can be used even though Apple has already stopped signing iOS 5.1.1.

11. In RedSn0w go back a couple of pages and select Pwned DFU - this will put your phone in Pwned DFU mode. Thanks to this, you will be able to restore to the firmware obtained in step 10 through iTunes. Otherwise, .

12. Open iTunes. The program should automatically detect that your device is in recovery mode. Hold down the Option button (in the case of Mac) or Shift (in the case of Windows) and click in iTunes on the button Restore... In the window that appears, select the firmware you created in RedSn0w.

13. Wait for iTunes to finish restoring the firmware. During this process, a "-1" error may appear in iTunes. If this happened - open RedSn0w, select the item Extras -\u003e Recovery fix... Put the device in DFU mode.

14. After the completion of the Recovery fix process, your device will be fully restored to iOS 5.1.1. Congratulations!

If you strictly followed all the instructions, then the firmware downgrade should be successful. Please be aware that this guide is only applicable to certain devices (iPhone 4, iPhone 3GS, and iPod touch 4G).

  • Prefix Sony Playstation 3 with official software 3.55 or the version below. Firmware 3.56 and higher are not yet supported.
  • A flash drive or USB hard drive formatted with the FAT32 file system.

Preparing for PS3 firmware

Check the software version of the set-top box at the moment. You can do this as follows: go to the PS3 menu in the section "Settings" - "System settings" - "System information"... The screen will indicate the current software version of your STB.

1. Installing the official software update version 3.55.

If you already have firmware 3.55 installed, then proceed to installation (as I wrote above, set-top boxes with software version 3.56 or higher are not yet flashed).
Make sure that the file system of the media used (USB HDD or flash drive) is FAT32, if your console "sees" its contents, then the flash drive is already formatted in FAT32. Create a folder in the root of your USB drive with the name "PS3" and the subfolder "UPDATE" (observing the specified case). Download the archive with the official software update to 3.55, unzip it and copy the official firmware file "PS3UPDAT.PUP" to the previously created PS3 / UPDATE directory. Connect the flash drive to the Playstation 3 console and select from the menu System update - Update from storage media... The STB will update. After the installation is complete the PS3 will shut down, now turn it on and check the software version is 3.55.

2. Installing custom firmware 3.55 kmeaw.

Download custom firmware 3.55 kmeaw and run it. Specify the path to the flash drive, the installation will be performed on it. Connect the USB flash drive to the console. Now you need to completely de-energize the Playstation 3 (switch the toggle switch on the back - FAT models, to pull out the power cord - Slim models). Power on the set-top box again. Press and hold the power button of the set-top box until it turns on and turns off by itself (about 30 seconds). Press the button again and hold it until the attachment emits a short beep twice. After the beep, release the button. The Playstation will boot into recovery mode.
Connect the joystick with a wire, press the "PS" button and select "System Update". The Playstation 3 will begin installing the kmeaw custom firmware.
After the console completes the update and reboots, two new items should appear in the "Game" menu: "Install package files" and "/ App_home / PS3_GAME".

Installing multiMAN manager to run games on custom firmware.

multiMAN is considered the best manager for running games on custom firmware.
Download multiMAN 2.03.00 and BDEMU Blu-ray drive emulator, copy the files to the root of your flash drive and connect it to Playstation 3. Via the menu "Games" - "Install Package Files" on the set-top box, set the joystick button "X" first multiMAN, then BDEMU. A drive emulator is necessary, because in the latest version the developer has removed the ability to run backups.

Burn games that you will download from torrents to an external drive or USB flash drive. On the external drive, at the root, create a folder "GAMEZ", and inside it folders with the game code.

Attention! To avoid errors at launch, check the correct sequence of folders, as adding sub-directories to the game path will not start the game.

How to run a game on custom firmware

Go to the multiMAN manager and press the "X" button on the game - the game image will be mounted and a new icon will appear in the "Game" menu: if any Blu-Ray disc is inserted into the set-top box drive - the game will appear in the disc section, if there is no disc in the drive - in / app_home / ps3_game).

Attention! Not all games come without a disc, some require any Blu-ray disc in the console drive.

Downgrade on PS3 consoles with firmware 3.56 - 4.46 (firmware rollback)

Downgrade (from English - downgrade) is the use of the old software of the device. Downgrade, as an operation with a device, is used to rollback the firmware due to the greater stability of the early firmware or to obtain the possibility of any manipulations with the device. Owners of the PS3 console with firmware 3.56-4.46 can use a special device - E3 Flasher, which can downgrade the console firmware, that is, downgrade. E3 Flasher is a special chip that is installed inside the console to be able to rollback to an earlier version of the firmware, respectively, to install a custom one.

Downgrade, as a rule, is done to custom firmware 3.55, since this particular firmware is completely hacked. After rolling back to an earlier firmware version, you can install custom Rogero 3.55 v.3.7 or (or Kmeaw 3.55 - instructions in this article).

Conditions under which PS3 downgrade is possible:

  • The Date Code of the prefix must be no higher than 1B (this means that the prefix must be produced no later than Q2 2011). You can view the Date Code on the back of the console. Let's say 9D and 0C are suitable, since the set-top boxes were released in Q4 2009 and Q3 2010, respectively. 1C, 1D - no longer fit (3, 4 quarters of 2011). Also, your PS3 memory must be NOR type, as indicated by the following model numbers: CECHH, CECHJ, CECHK, CECHL, CECHM, CECHP, CECHQ
  • Your console's factory firmware must be below 3.60.
  • Slim models with model number 3000 cannot be downgraded.
