[Nexus 4 Q&A, Help & Troubleshooting] KIRGO:
Hi!

I'm sorry I won't be able to help you a lot because as you I'm new to xda, but i'm really interested in hacking the bootloader, therefore your subject is interesting =)

This is what I believe, after my researches in the source code of Android (tell me if you think I'm wrong): The problem is, the source code for the bootloader doesn't seem to be given.

What is given is the source code and the functions needed to build "boot.img". For example, we have the "mkbootimg" function, but that's it, nothing for the bootloader, except the python script you gave.

Therefore, the only option is to take the bootloader.img given by the update, and to hack, as some people did with the boot.img (thanks to perl script), but we do not have lots of informations about the bootloader.img =S I've opened bootloader.img with an hex editor, but I'm not used to it and I don't understand that much except the header thanks to the description given in the python script. Perhaps it is possible to unpack this .img but nothing sure...
[Nexus 4 Q&A, Help & Troubleshooting] KIRGO:
Hi,

I've made some discoveries, here is the composition of the file bootloader-mako-makoz10o.img

There are 6 differents parts:

sbl1

sbl2

sbl3

tz

rpm

aboot

Their sizes are the following (/!\ only for bootloader-mako-makoz10o.img!!):

taille de sbl1 : 94440

taille de sbl2 : 145448

taille de sbl3 : 1430152

taille de tz : 190572

taille de rpm : 144892

taille de aboot : 234704

Therefore, I googled "aboot", and I found this:

Moboot (Mobile Open Bootloader) was developed for the HP Touhcpad and is based on the little kernel by Travis Geiselbrecht. But it was planned to be used for other devices:

The code is available on code.google.com/p/moboot

Perhaps the Nexus 4 bootloader is inspired by this moboot? (this is only an hypothesis)

bye!

open source bootloader

Indeed it is. w/o the help of a developer board community [the kind of low level technicians we'd need], its darn near impossible. But history lesson: LK bootloader was nice; it was a project on codeaurora [where qualcomm dishes a small bit of open source help out once in awhile], but unfortunately I think that project is defunct [hasn't seen updates in like 2 years]. Moboot... I'm familiar with it [got a hp touchpad]; it was used by hp but they've dished their wares to LG and LG is revamping webos for smart tv usage methinks. Still, I beleive some of the wares did see open source light, and their might be a moboot floating around under the MIT license. Best bet [if we had the balls to build and test it] would be uboot or das u-boot. They've ported that one to gnex; I don't doubt the panda board community helped in that venture, but that's omap and we're qualcomm; so, its a whole new ball game. I'll ride with you should you like to try. First problem [after we port such] would usually be the sacrifice... The open source bootloaders I've had experience w/ do NOT support fastboot natively. On the plus side though, they do open the door to true multiboot [w/ separate kernels & protected system, unlike kexec], but again its a swap out/sacrifice some would go for. I'd help just to have it be free and open source. But before you or I trod down that path.. I gotta find my ripcord for writing back the stock bootloaders [for when things go awry]. Gnex had omapflash. I'll check and see if there's some solution for us [like riffbox or something that uses QDM driver(s)].

Rob

Update: Checked into it... and riffbox supports this device [even for bootloader ref: http://www.riffbox.org/jtag-news/riff-jtag-lg-e960-nexus-4-lg-mako-boot-repair-supported/ ]; so, I'm golden; as I have a riff ;)

Update2 small[er than panda board] development board community.. still gotta find it, but I spied the boards. Ref: http://www.inforcecomputing.com/product/6400series.html

@OP why don't you simply flash stock JB firmware via PC Odin ?

If you want OTA update top jb, you'll have to use stock ICS which isn't safe (the kernel, I mean).

[General Questions and Answers] sventh7:
About the phone:

1. I dont know the exact phone model, but it is Cloudfone Ice plus. There is a phone called Cloudefone Ice (Huwawei u8500) but i dont know if mine has another name.

2. It looks like this,

h++p://cdn2.sulitstatic.com/images/2012/0926/222830332_22162996997ba02ceb979675b8093b33516b3b725d6504ce0.jpg

3. Adroid version 2.2.1

4. Detected as "Globe Phone" in Google Play Market. *Globe is a carrier in our country.

The Problem:

When I turn it on, the android logo appears, and stays like that forever.

Cause:

After I tried to install a custom ROM using update.zip in recovery mode, the process got aborted in the last part of the installation.

5. I'm not sure if it's fully rooted, I have superuser but when I tried Root Checker before, it's not.

Other info,

I already tried to boot in recovery mode(it's the only mode that I get into now), I wiped data and cache/factory reset.(still stuck on boot screen)

I tried to install other Roms(update.zip), but all gets aborted in the beginning

I tried to download an update.app file in a dload folder in the root of sd card(firmware for huwawei)- I can't go to update firmware.I can only go to recovery mode.

I tried adb, I can use adb devices, it shows MT(serial number)

adb shell shows adb shell exec '/system/bin/sh' failed: no such file or directory exists

superboot cant detect the device.

I boot the device using power button+volume up,

when I use power+volume down, android logo appears and "Factory Mode" in the lower left (then It stays there forever, whatever button i press)

These are the infos that I can give, please help, I'm looking for fixes since yesterday from google and forums but no luck, nothing works so I decided to post my own.

[7 Mozart General] ikhwanikan:
Hi,

I have a HTC Mozart 7 T8698. The phone always restarts itself and there's a moment where the phone vibrate 6 - 7 times and stuck at the htc boot screen. :crying:

Here's some technical information about my phone:

OS Version: 7.10.8773.98

Firmware revision number: 2250.21.51205.707

Hardware revision number: 0004

Radio hardware version: A.102.0.D4

Bootloader version: 5.12.2250.5 (139188)

Chip SOC Version: 2.2.5.0

I've heard that downgrading the SPL would be the solution. But i don't know how to do that and which suitable ROM should i use to safely downgrade my phone. For your info, I have a Y-cable, a SD-card, a SD card reader.

Hope you can help. :good:
[Desire Q&A, Help & Troubleshooting] KenuR:
So after I wiped data from my Desire, I found that the play store has stopped working. I can still search for apps and browse, but when I try to download any app, it just gets stuck at the "downloading" stage (doesn't even show progress, only shows the little grayed out bar). I also found that some apps that need internet connection work (Browser, Google Talk, some games and even other alternative markets like Aptoide and AppBrain work fine) while others don't (Facebook, Email, most games that require internet connection).

I have a rooted HTC Desire GMS with CyanogenMod-7.2.0.1-bravo. Android 2.3.7.

Here're the things I tried:

Wiped sd-ext from recovery mode. After that I tried downloading an app from the play store and it worked. The next day I tried downloading another app and it didn't work anymore. I tried formatting the sd-ext several times again, this time it didn't help.

Formatted all data, and formatted the SD card. Wiped cache, dalvik cache and fixed permissions. Didn't work.

Formatted all data again, and re-installed CyanogenMod 7.2.0.1. Didn't work either.

I don't really know what to do anymore, any help would be greatly appreciated.

[Nexus 4 Q&A, Help & Troubleshooting] Gambler_3:
Ever since it was introduced no phone has been able to quickly swipe through it without lag. I thought that the galaxy S3 had lag in the drawer because of lack of ram but its shocking to see that even the nexus 4 widget drawer has lag if you swipe very fast.

Whats most puzzling is that the widget drawer is only showing static widgets so I dont understand why it is so demanding. Seems like its not handled properly in the framework or something.
[Nexus 4 Q&A, Help & Troubleshooting] LoVeRice:

[Nexus 4 Q&A, Help & Troubleshooting] JamesInsights:
It's totally fine on mine and a lot of others phones. The reason the S3 lags is cause of the touchwiz skin weighing it down. Touchwiz sucks. That's why nexus-es with stock roms FTW!

I don't get why people purposely try to lag down their phone by doing something they would never do in daily use (opening and closing as many apps as possible as fast as they can, swiping around as fast as humanly possible, etc) and then complain about lag? Just use the phone then see if it lags
[Nexus 4 Q&A, Help & Troubleshooting] Nigeldg:
Nah, that's too logical for the internet :p

@OP, I see what you mean and I experience the same thing but only if I actually try to make it lag. It's probably due to some sort of lack of optimisation, but tbh I just sorted out my homescreen once and don't really go back and reorganise it so I don't see any issues. I know that you're not complaining but just asking about it, so I thought I'd confirm that I have the same experience.
[Nexus 4 Q&A, Help & Troubleshooting] Gambler_3:
For some reason the widget drawer is much faster with vertical scrolling.

Nova launcher just delays the animation in the widget drawer if it can't show it fast enough but on stock launcher it will actually cause a stutter. The developer of nova launcher is an absolute genius.

I still don't see a technical reason why a nexus 4 can't just blaze through the widget drawer.

The guy talking about the xperia Z launcher well its handled very differently and mind you more efficiently in Sony launcher.
[Nexus 4 Q&A, Help & Troubleshooting] Gambler_3:
Actually this isn't true for this case. When I want to select a widget that's at the end of the drawer then I would swipe as fast as I can to get to it. Infinite scrolling causes even more performance issues with the widget drawer mind you so that's not a better option in this scenario.
[Nexus 4 Q&A, Help & Troubleshooting] v3rk:
It does lag, it's true.

I run stock now but have tried all different roms and kernel combinations. And then all different governor/scheduler combinations. Swiping quickly through widgets always produces lag after a few pages. Even using nova/apex.

It doesn't bother me anymore (used to when I was a crack flasher), but it's undeniable.
[Nexus 4 Q&A, Help & Troubleshooting] JamesInsights:
Just install a different launcher like Nova lag free.

[Nexus 4 Q&A, Help & Troubleshooting] Greenly:
I'm experiencing this too. Thought i was the only one!

It happens occasionally on mine though when i swipe real fast. Sometimes it lags terribly, like, i could see the pages stutter and struggle to load the widgets. And sometimes it's just super smooth.

Don't know for sure, but maybe it has something to do with some of the apps installed. Because the lag always happens on the exact same pages i swipe through. Mine is on the first 3 to be exact. And that's where all of my google widgets are placed, strangely.

Maybe it's just an issue with my device though. Running rooted stock 4.2.2 btw.
