Firmware Thanks for the FAQ
ilnur.zamanovQ: I flashed the phone with firmware, but everything is slowing down for me, what should I do?
A: The phone after the firmware, for some time, namely, 7-10 restarts optimizes its work, i.e. after this cycle, the phone will enter the "combat" mode.
Q: In what cases do I need to do Data-Wipe?
A: If you are switching from stock, or any other firmware or from Cyanogen 7.0 to nightly (Cyanogen 7.1), Data-Wipe is required. But in any case, Vipe will never be superfluous. (data on the flash drive is not erased)
Q: The phone freezes on startup on the words "ANDROID" or the MIUI splash screen
A: Restart the phone in Recovery and do a wipe data / factory reset or boot the phone in safe mode and reset the settings.
Q: How to boot the phone in safe mode?
A: Hold down the power button and after the "samsung" message appears, hold down the menu button. Hold the menu button until "Safe Mode" appears below.
Q: Is it possible to install a newer hotfix for the current firmware without installing the previous hotfix?
A: Yes. Each new version of hotfix contains corrections from the previous one. That is, even if for some version of the firmware there are 10 hotfixes, then you will only need to flash the last one, and not everything in order.
Q: Will the warranty fly off?
A: Yes.
ClockworkMod Recovery Q: How to get to the ClockworkMod Recovery menu?
A: To start, ClockworkMod Recovery needs to be flashed (firmware instructions are here), after that there are four ways.
The first one to flash CWM again, after the firmware in rekoveri, it will again go down automatically.
The second of Cyanogen (with the CWM already flashed) select "Restart>recovery "
Third, useful when there is no access to the menu of the Digital Brain, in the command line on the computer type "adb shell reboot recovery", for this, the system must have adb installed on the system
Fourth, from the menu of the program ROM manager (not yet recommended)
There are no shortcut keys for loading into Recovery.
Memory expansion Q: How to break a USB flash drive using ClockworkMod Recovery?
A: After ClockworkMod firmware we do BOTH wipe, and in the ClockworkMod menu go to Advanced ->partiton SD card for breaking a flash drive into ext4 and swap. We select the desired values, but EXT4 - no more than 900 MB, SWAP no more than 256 MB
Q: How to expand the phone memory on SD?
A: In fact, now you do not need to mount the system partition on a card, just create mount points using the program В® S2E (simple2ext) which mounts folders on a previously created ext4 partition to store various data. Instructions for working with the program under the spoiler
Install В® S2E (simple2ext)
Open S2E, press menu key ->Settings. Enable "Connect as ext4" (required) and "Set read buffer" (not necessarily, can improve performance). Selecting "Advanced Mode" is not recommended, as this will cause strong lags.
Close the application and restart the phone.
Open S2E, select the folders you want to place on the SD memory card, and then close the application.
The changes will take effect at the next reboot.
Q: Do I need to split and format the flash drive?
A: If you want to squeeze the maximum out of the phone, then yes.
Q: What is the threat of using madconfig and S2E?
A: Eternal residence of the flash drive in the phone, i.e. if you take it out, you will lose the data, because The flash drive becomes part of the phone, it actually integrates into the system.
Q: Earlier, on the factory firmware I had more than 100 megabytes of free memory, why, after the firmware, it became so small?
A: Android 2.3 has more services than 2.2, and therefore consumes more memory. The simplest analogue of Windows 7 and Windows XP. But the performance of android 2.3 is higher than that of 2.2, and it also allows you to use the memory expansion on the card through a swap, then the performance gain still occurs.
I flashed MIUI, but madconfig "writes" that the flash drive is not broken, what should I do?
A: Just insert the USB flash drive and reboot into recovery mode (for example, adb shell>reboot recovery) and make a wipe. Or, as an option, flash the phone again, but with a correctly formatted flash drive.
Q: How to change the card when using mad2sd for larger / smaller ??
A: If you want to remove or change your SD card, you need to completely disable S2E, mad2sd and swap before doing this.
Q: What are the pros and cons of using swap, porting programs and cache to the ext-section of a flash drive.
A: Pros:
1. if there is a shortage of internal storage, it allows you to transfer data to an external storage device in a larger volume than the standard app2sd
2. swap file to flash drive (mad2sd swap)
3. the ability to work on a computer (with installed Linux) with a section where programs are installed
4. when connected to a computer (with Windows installed), the ext-partition remains mounted in the phone, which allows programs installed on the flash drive to continue working.
5. the ability to transfer widgets to an external drive
Minuses:
1. there is no option to disable the flash drive
2. large energy consumption for working with an external flash drive than with an internal
3. shorten the life of a flash drive, due to frequent recording on it
4. malfunctions are possible
Performance Q: Can I overclock the processor?
A: It is possible, but it is not worth abusing this much.
Q: What are the optimal performance settings \ reasonable battery consumption should be set?
A: Here, everyone digs for himself, my settings became optimal with the swap turned off and the memory compression turned on by 18%. Include in performance settings, subcount Compcache
Q: Does Swap need, what is the optimal size for it, how to turn it on?
A: Swap is enabled by the madconfig swapon terminal command, and its necessity is determined by the severity of the applications that you intend to run. Recommended volume no more than 100mb.
General issues Q: "madconfig", what is it?
A: Since version 1.5, the madconfig command appeared, which must be executed in the terminal after the "su"
Syntax:
madconfig displays command information
madconfig dton - enable dual-touch
madconfig dtoff - disable dual-touch
madconfig swapon - enable swap
madconfig swapoff - turn off swap
madconfig tweak - tweak drives for speed
Q: After firmware, the accelerometer does not work.
A: Make the accelerometer calibration with the GPS-status application (first reset, then calibration). If it does not help, reinstall the firmware and / or make a wipe.
Q: I was going to flash MIUI, will I restore contacts through KIES?
A: No, Cyanogen is not compatible with KIES, take care to save contacts. Or export to a USB flash drive, or sync them to your gmail.com address book
Q: I can’t install Gmail and other programs from Google from the Market
A: Install
В® Market Enabler, select in the settings of the operator [US] T-mobile.
Q: How to change the card when using mad2sd for larger / smaller ??
A: If you want to remove or change your SD card, you need to completely disable S2E, mad2sd and swap before doing this.
Q: What is adb?
A: This is a phone management tool from the command line.
Q: Adb control commands from the command line on the computer do not work for me, what should I do?
A: Download and unzip the adb.rar file from "Drivers and Utilities" into the windows folder
Q: What should I do if a flash drive is not detected when connected to a computer?
A: You need to go to the dispatcher and assign a drive letter.
Q: The battery runs out very quickly. What to do?
A: Disable auto-rotate screen. Calibrate the battery program -
В® Battery Calibration.
Q: How can I take screenshots on 2.3?
A:
В® Screen Shot ItQ: How to return the stock firmware 2.2 / 2.1?
A: First flash
I5500-downgrade.tarand then stock firmware.
Q: Why is it necessary to use this "I5500-downgrade.tar" when returning to stock firmware?
A: Because the data section on the phone is formatted in ext4, and the stock firmware can only recognize the RFS format. I5500-downgrade.tar will bring the internal memory format to RFS and you will not encounter a cyclic reboot problem.
Q: There is no battery indicator, what should I do?
A: Go to Settings-Personal-Toggle settings-Battery indicator style and select Top-Bar.
