ZTE 768 Kernel Advice - General Questions and Answers

Hey Guys,
I'm a total n00b to android but have plod through and made some headway in the last few weeks.
I've manages to root T-Mobile Concord ZTE 768, Install and use SU and update phones SU binary to the latest 3.1.1.
Install Link2SD, BusyBox, a startup manager, Swapper 2 etc.. and formatted into three partitions a 16gig sd card leaving a little less than a gig as linux swap partition following directions I found here.
Everything works great Super User permissions all granted as they should.
No matter what I have tried and extensive googling, trial and error I cannot get Swapper 2 to succeed and am coming to the conclusion my kernel
Kernel Version 2.6.35.7+ [email protected] #6 does not support swap, I could be wrong.
Being very new, could use some advice; should I give up? perhaps I'm missing something?
Replace Kernel with a better one? Where would I even find one? Are they specific to certain phones? Directions to get it done?
I'm doing pretty good I think for three weeks into android, friends around me with androids for years, most don't have a clue and can see their phones are way bloated and messed up.
Thanks for any advice!
Best Wishes,

Best ROM for my Hero?

Hi guys,
am new to this whole rooting/ROM updating thing.
Would appreciate if someone could guide me to a good ROM for my HERO (currently running stock 1.5)...its an Eastern/Central European version (i.e. has language for Czech, Hungary, Poland etc) and has no market place.
Basically the ROM I am looking for should:
Give market ability
Android 2.1
Fast to use
Give a better/more practical contacts selection option...i.e. the fastest way to select contacts (bypassing having to go through multiple screens!)
Be generally cool and not make me want to buy a new android phone for the next few month!
would also appreciate instructions (or link to) for how to update the ROM.
thanks!
Raidroid seems happiest on my hero from the handful I tried so far

do you have a link where I can get it from (including instructions)?
thanks
I installed Fresh 2.1.2 a few days ago and am loving it! Looks slick and is fast.
I think in terms of speed, any of the 2.1 roms are great when the hero is overclocked (OC).
I had been using BeHero 1.2+ before the OC patch came out and it was occasionaly sluggish but after I applied the OC patch it is perfect now. LAGLESS
what i really need are links where i can download these things from...from whatever i've found, it seems to be through rapidshare.com which doesn't work...
Latest raidroid is here: http://www.multiupload.com/C54GAT6DLJ
thanks! finally found a site from your link that lets me d/load
Glad to be of assistance, is what we're all here for after all
Whatever ROM you install, I recommend that you install SpellDial to search for your contacts (it is free).
It gives you a T9-style search of your contacts. Type in the name on its telephone keypad and the you will usually get your contact listed within 3 to 4 key presses.
SenseUI already does this.

hello again
now that I finally downloaded this, I don't know how to install it!...
I have an unbranded Hero (i.e. not locked to any network)... do I still need to root my phone first etc?
where can I get instructions on how to install the ROM?
many thanks!

yup...you need root access to install ROMs. Google Search on how to unlock your version of the HERO. Good Luck!
What he said.
Google 'how to root HTC hero'
Basically:
allow 3rd party installs, dl and copy the Rom zipfile, flash backup/loading tool and the recovery image to SD, install the tool, run it, backup, then flash the recovery bin to the phone, power off, power back on holding home and power until the green on black text recovery screen comes up, wipe all, then flash from SD and select the raidroid zip
Will take a few mins to flash and reboot, reboot will take a bit longer than usual but that's it in a nutshell.
Good luck ...
ok.. so the day started off with trying to root my hero with the 'one click' unlocker...
finally d/loaded the program, ran it but it somehow couldn't find my android phone (on Win 7)...
wasted a couple of hours on above, then tried it on a WinXP machine... found phone no problem, ran the one-click unlocker and got an error while trying to 'update' (i.e. downgrade ROM)...
so then thought I'd give the 'goldcard method' a go...
followed instructions to the letter...got as far as trying to write the image on the SD card till when I pressed save (on the hex editor) and it gave me a 'cyclic redundancy error'...
not sure what the heck that means!... don't know whether it had anything to do with me not formatting the SD card when sticking it in my PC since WinXP said it needed to be formatted....
however, the instructions didn't say anything about formatting it!... tried to re-insert it and format it but don't get the format option this time....
SD card works fine in phone...
Don't know whether its to do with brand of SD card not being compatible with the 'goldcard' method (San Disk)... read that Kingston works... can't be asked with all the hassle and going out to buy a different one etc etc...
Hoping that a new ROM is released by HTC officially, soon!

[Q] ROM's, Kernals, Recovery's and ROOTING?

Hi Fellow old and New Devs,
The title suggests it all. I have four questions that I think ALL newbies want to understand. I would try and explain them, but as I am just coming out of the newbie stage, I'm sure people would prefer an answer from a experianced Dev.
When answering a question please put the Question Number. Feel free to answer only one or two of the questions, I'm sure other people will cover your missing fields of knowledge.
Here they are:
1. What is rooting? Can I root my device (HTC Buzz Wildfire) and keep the stock interface? Will I loose my data?
2. What do all these Dev's mean by Recovery? What are they, why are they needed?
3. What is a ROM? Do I need to be rooted for a custom ROM? How can you trust them? Will I loose my data when installing a custom ROM?
4. What is a Kernal? How are they Different to ROM's? Should I change from the stock Kernal?
I know this is a tall order and you could write a book on the topic, but please could you write a short (a couple of sentaces will do) paragraph on each question you choose to do.
When we get enough understandable answers I will edit this post publish the Final answers for other newbies in the future.
Also feel free to enter the poll! As this is a Dev site I presume one of the options will have the most votes but we will see....
Cheers for any contribution in advanced.

Okay, from the best of my understanding, here we go:
1: Rooting. To understand this, we must consider a computer, running linux, windows, or mac. In windows, the "Administrator" account is similar to the root account in linux and mac. Basically if you have root privileges in a system, you can modify every part of the filesystem, as well as perform any tasks the system is equipped to handle. Basically achieving root on an android device means that you can unlock the ability to flash roms, mod, and otherwise hack your device any which way you like. Nearly every model of android device has been rooted, so in most cases, yes you can root XXXXX phone. Also, since you're just gaining privileges, you can root without losing any data, apps, or settings.
2: Recovery. This is a long standing concept in SoC/Embedded device hacking. Basically it is a minimal operating system that performs some very basic, but very important tasks. The reason for it is so that you can write to the necessary areas on the NAND, which would be "busy" while android is booted. This offers a way to access the necessary partitions and write data to them while the data is not being accessed. It's also useful for backing up your NAND. Hence the name "nandroid."
3: ROM. By definition, it means "Read Only Memory." This is a chip on the board. ROM has evolved over the years. It started out as a chip that was sensitive to UV light. The earliest ROMs were "flashed" to a device by stenciling out the pathways and exposing the chip to UV radiation. Nowadays, we have fancy EEPROMs instead, which stands for Electronically Erasable Programmable Read Only Memory. This means that you can "flash" the chip by means of software, namely via Recovery mode in our case. Different ROMs have different features. They are all variations on source code made available by AOSP, or the android open source project. Some projects have their own code tracking, such as CyanogenMod. In most devices, you must be rooted to be able to install a ROM, however it is not explicitly necessary. A bit vague, I suppose. Specifically the tablet I own, the WITS a81e, you can flash a ROM to it just by putting the correct files on the TF card. This is not very common with phones, however. Flashing any rom that is not just a newer version of your current ROM will require a full format. For instance, if you have cyanogenmod and switch to a Sense or Blur ROM, you must format, but if you update from CM6 to CM6.1 you will not need to wipe. How can you trust ROM's? Well the best way to know is to either roll your own, or go with CyanogenMod, as their source is freely and easily available for scrutiny and improvement, along with a nice changelog tracker.
4. Kernels. A kernel is basically the most low level part of an operating system. It interfaces directly with the processor and provides all instruction for operation. Linux is technically not an operating system, it's a Kernel. The different distributions have the Linux kernel, and use their own different User Interfaces. Different kernels in android devices can allow you to overclock. There are many choices in kernels, and the features they offer. Some features are BFS/CFS which is the priority scheduling of processes. Some kernels allow you to charge your battery differently and conserve life. These are often called battery kernels. Also, some kernels unlock extra multitouch points in certain devices. There are different versions of the linux kernel, with many improvements with each iteration. Currently, the latest kernel available that I know of for android devices is 2.6.37. The froyo default kernel was a 2.6.32. I wish I knew a bit more about kernels, however this is about all I know. Perhaps someone could help us out and expand on this a bit?

Can't ROM
Gotta be something stupid......
Can't install 2.2 or 2.3. Tried two different ODIN flashers. When I do the reset I do not get the triangel with downloading in the center. I'm rooted, Have ROM Manager, Superuser, Root Explorer, Super Manager, I'm unlocked.
I have Android SDK, Congnitive 4.1, NPS, Samsung Kies,SGH I897 USB Drivers, What else? I think I have it covered. In any case I never get the download . Even if I do a "ROM Manager Install fron SD Card, the result is a screen, blue at top and yellow at bottom with the last line saying "Installing Multi- CSC. I can let it run all night, no change in ROM. Does the Captivate sold by ATT have some kind of block or filter keeping me from updating?
Current firmware is 2.1 update 1, baseband I897UCJH7, Kernel 2.6.29 [email protected] #2, Build ECLAIR.UCJH7
Thanks

didn't know where to ask this?
hello, everyone..
i have some questions, i'm hoping some of you can anwser.
I used unrevoked to root my htc desire. after that, I used alpharev to gain s-off.
everything went fine, i got the joker, the white screen that lets me pick different options..
now Í tried all those options, nothing works.
I've been searching all night for a solution, and it seems my recovery boot and rom are missing? and what I came across is installing ANDROID SDK tools, and then run fastboot to recover an image. So I installed SDK tools, but fastboot doesn't run, it says some .dll driver is missing. in the platform-tools map is that .dll driver, should i move it?
Can someone get me a step by step tutorial on how to make my desire work again? Im kind of a noob, all I needed was to make a screenshot..
Thanks in advance, it would be appreciated so much..
Pyroboy, I'm using a Samsung Captivate. In another thread someone lead me to "All in One Toolbox". The other stuff is just stuff. That allowed me to install my ROM.

Kernel for Xoom with 3.2.2 and 4g sim installed.

I just got my xoom back after getting the 4G LTE sim installed and the 3.2.2 version of Honeycomb.
I have rooted it again and restored my apps and data, but am stuck on a lot of things work related since there is no kernel that provides tun.ko and keeps 4g working.
Is there a kernel being built that provides tun and 4g or maybe possibly a Moray type rom that has 4g support? (That would be super sweet).
Dude the only one was in the universal root thread. If you changed kernals I think your stuck till we can get the img.
Sent from my Xoom using xda premium
I used the Universal Xoom Root process available in Development. It gave me back root access and superuser, but the kernel is still stock and lacking write access to the microsd card and tun.ko in the kernel so that IPSEC VPN connections work.
Was just searching around to see if a kernel with 4g support was in the works. Was going to use the Rogue kernel, but there is a post about waiting until it can be updated to handle 4g access.
I will just sit back and monitor the forum for an update.
The Tachi kernel is working for a few people so far. I don't live in a 4G area (VZW says it will be here next month), only work in one so I can't test the LTE yet, though the 3G works fine from my home.
I've identified a few minor annoyances and work arounds as compared to running the kernel (and Moray ROM) prior to 3.2.2 HLK75D as listed in this post:
PengLord said:
Interesting... I installed File Manager HD, enabled Root Explorer (in the settings menu) and it prompted for Root permissions. It works great. The next step in resolving this is going to be remounting the external1 device on boot to enable global write support. As I'm not so well versed in Android architecture to do that, I'll use MicroSD Mounter manually on boot.
The final step to getting this all sorted will be for me to figure out how to mount usbOTG devices, If anybody has experience with that on this kernel with a 4G Xoom, I'd very much appreciate it.
I figured out my problem with usbOTG support... I needed to added the "usbOTG" folder in the "mnt" directory using Root Explorer and then install a mount manager such as USB Mass Storage Watcher OTG
Click to expand...
Click to collapse
This will get you set up with R/W support for the external1 folder and usbOTG, VPN support may be in there as well since the kernel supports it, I however haven't tried it nor have I read about it being tested as functional on the HLK75D build.
Sadly solarnz announced he will not be working on a 4G Tiamat ROM due to life getting in the way, this means we will likely need to wait until another dev gets caught up or until ICS gets released to us by Motorola (fingers crossed for next month) before it gets any easier.

See the arcturus kernel thread over on xoomforums... there is now an open beta for a postupgrade kernel if you want to try it
Hi Etchg,
I had a similar issue. I sent my Xoom in for the 4g update. When it came back I rooted it. Trying to vpn into work (ipsec) I found that my new kernel 2.6.36.3-g6963abe has no tun.ko file. I found some instructions online and compiled one myself. Attached is my tun.ko (You will need to unzip and put in the systems/lib/modules directory. If your kernel is exactly the same as mine then it should work. BTW, with the new tun, I have successfully VPN'd into my work.
-Jared
I just came back to this thread and saw the tun.zip you uploaded. I tried to open it, but it tells me it is corrupt.
Can you either upload it again or use dropbox and send me the link?
I was able to extract the module and load it on my Xoom. I have the same kernel, but I keep getting an authorization error when I try to connect. Darnit all to heck!
I fixed the authentication issue I was having. Thanks for the module...works like a charm.
Thanks for compiling the tun.ko. It works correctly with Cisco AnyConnect for Rooted Devices.
Glad to help
Hi Guys,
Been absent for the week. Glad to hear that you got it downloaded and working!
-Jared
This always comes back as corrupt for me. I've tried everything I can think of, but I can't extract the tun.ko out of the zip. I haven't been able to create my own either, so I'd really appreciate someone posting this.

General Android questions

I'm pretty comfortable with *nix os, however, I've just gotten into android. Typically I run a barebones/minimalist openbox setup on my pc's. Android is driving me crazy with the open processes etc. Is there a reason why so many programs are continually queued up almost instantly after being force closed? **** I never ever use is robbing ram/battery for no reason?
android is not windows.The memory management differs.Android uses as much as possile ram to keep applications open for multitasking and for faster application launches
Rooting SGS2+Stock Kernel
Hello there!
I had earlier installed official firmware 2.3.5 on my SGS2. A few days ago, I decided to root my phone so I just used the insecure kernel by chainfire (XWKDD). I have the superuser app but not busybox (which I will be able to dl from market or so) but the problem is that I have also read another topic on rooting where it said 3 steps to root the device as 1. Flash an insecure kernel 2. Root using SuperOnceclick or S2Root 3. (Optional) flashing back the stock kernel to get rid of the yellow triangle on reboot screen.
Now, I am just wondering while I have just used chainfire's insecure kernel but I have the superuser AND I haven't even used superoneclick or S2Root!!! On the other hand I want to get rid of that yellow triangle on reboot.
The question is that whether I have missed anything out there!? And additionally Where can I find a stock kernel for my 2.3.5 firmware?
Any other useful tips are strongly welcomed ESPECIALLY by professional androidees!
Thank you in advance
Thank you for the kind responses!

[Q] Identifying and routing my mini android phone

Hi all,
Background:
I bought an android phone from Chinavasion. It is described as
Wholesale Waterproof Android Phone - Mini Android Phone From China
I cannot identify its device type which is why I am posting here. The play store identifies the phone as
Alps Ratech72_wet_rlk_lca
The phone has a MT6572 Dual Core 1GHz CPU and runs Android version 4.2.2.
I want to increase the ram of the phone. It is 256MB. I want to use virtual memory. I have a 2GB sdcard in the phone. I am planning to give it 512MB. Can I do this without rooting? If I have to root it, then how do I do so? I would prefer not to use an exploit.
Anyone any suggestions?
Pranav
Hiya,
I went around looking for some hints on this phone as well but didn't come up with anything.
I got my device yesterday and I understand your issue. I have no sollution for you but I do have a solid work-around to get some more app space which, I'm afraid, involves rooting.
Activate USB debugging, connect your device to a PC. Download and run Kingo Android Root and follow the instructions.
After that I "adb'ed" to make the phone choose the SD-Card as the default installing path. Run th following command with adb.
Code:
# adb shell pm set-install-location 2
For the apps that wouldn't move to the SD-Card, due to su issues, I moved manually with the app called Move app to SD card.
Grant the app root access to sort out the apps not willing to move by themselves.
With this sorted I now have 500 mb of apps installed on the SD-Card. I am running low on memory now due to some parts of the app still installs on the phone memory.
Not a real app2sd script but it certanly will get you some more apps installed!
Another hint: When I ordered the phone they said it supported 16 GB SD-Cards only but I'm running flawless with a 64 GB card!
I'd love to see a costum recovery (since I don't know chinese) and CM for this device, but since it's not a western phone I guess we'll have to settle with stock.
Hope this helps.
A few hours has gone by and without doing any backups I replaced some system apps and now I can bearly work the phone! Haha.. Thou shall not do this sort of thing after 2 h sleep.
Anyway, don't be afraid of doing what I wrote in the previous post, it worked just fine! I'm hoping you'll do it, it's the only way I can think of to get the system files back. :-S
Since there seem to be no one but you and me who have bought there phones..
edit: Sorted out my problem, got it running again! However, if you are going to root it, please do share the stock files! :-S

to use virtual memory you would have to root it and plus you cant get that much more ram with virtual memory, 256mb of ram on a 4.2.2 phone? i hope you got a good deal for it because 256mb will get you nowhere with nowadays google play apps updates hogging all the ram.
Some more info. Appearently the phone is also called "Nanex" and/or Z18 Mini Smartphone.. Maybe it's called different things in different regions?
Move to SD card SUCCESSFUL!
Im so glad there was this thread, it seems like nobody else knows about this awesome little phone!
I followed the instructions that "pingaan" posted and it worked! now i can install as many apps to SD card as i want, awesome!
I'm glad I could help.
I've been using this device for about a week now and I have to say that the stock rom is horrible! There are many flaws and no updates incoming, as far as I know.
Another disappinting thing is that the screen material is >VERY< easily scratched so DO NOT order this phone without screen protection.
I am going to order a new one cause I love that it's so small! It's even smaller than my old "dumbphone", but I don't see myself using stock rom. I'd rather not use the phone at all.
I'm going to try to compile a custom recovery and port a suitable CM11 rom to this device for proper usage.
Don't expect it any time soon, cause my days are normally filled up with family, house and work.
Regards.

everything about this phone is pretty good for the size, except the ram is so ridiculously small, i've tried to add virtual ram with link2sd and partitioned sd card, but apparently link2sd won't work without hacing the bootloader unlocked first, but i can't unlock the bootloader as it seems like there doesn't seem to be proper drivers for this phone.
if you are planning to do a custom rom on there, please let us know how when and how you managed to get the bootloader unlocked plz! :fingers-crossed:
Since I noticed the screen being easily scratched I ordered a new device from a different retailer, along with a plastic screen protection.
There is an interesting thing about this. The bootanimations are different and there's also a reboot option in the powermenu on the new.
Maybe the bootloader already is open? I mean, if you can change the power menu you need to alter the framework, right? The bootanimation is quite easy to change with root access however.
Have you checked the built-in recovery? There is actually an option for installing "update.zip"..
Do you have a proper app2sd script that I can try out on my old device?
Cheers...
Anyone have a backup of the ROM for ratech72_wet_rlk_lca ?? I plugged in a MTK Tool and I seem to have corrupted the system ;-( ... Didn't even get a chance to backup!
