Cannot downgrade to 4.2.2 (gt p5210), what should I do?

Hi,
After upgrading OTA to kitkat (australia version) one of my favourite apps stopped working and caused constant reboots to my tab3.
I tried to downgrade with odin to the stock 4.2.2 (auatralia, from sammobile) but I could not. After flshing, the "samsung galaxy tab 3" logo appeared but the tab never turned on, it kept rebooting and rebooting from ours. I tried the same with other 4.2.2 roms with the same results. However I was able to flash any 4.4.2 rom from sammobile.
After that I tried to flash some 4.2.2 roms using twrp and bindroid, I had the same rebooting problems. However, with twrp I can flash 4.4.2 based roms as pimpdroid.
So, I do not why, apparently my tab only accepts 4.4.2 roms... Any suggestions about what should I do to go back to 4.2.2?
Thanks for your time,
A.

Bootloop in P5210
Hi I'm trying to get back to 4.4.2 to 4.2.2 works because although there are excellent applications like Facebook that are causing me problems. But in trying to make the retoroceso as I usually do with ODIN stock form and I was left in a permanent reboot and does not pass the SAMSUNG logo .... solution? Thank you!:crying:

@planinsky, Have you tried a firmware for another region in the world? I live in the United States but have found firmware for the United Kingdom or Canada works best when I flash. There should not be any difference in the firmwares except for regionalization, but it seems some work and some don't work for me. Regional settings can always be tweaked in the Settings panel after install. Do you have a nandroid backup made in TWRP? Those usually always recover a device. I too had a problem having anything flash when I first started making my rom. 3 weeks I had a device that would not boot. So it is recoverable. Odin will save your device.
@planinsky and @MDCB try to download this firmware from Sammobile. This is for the UK 4.2.2 version. http://www.sammobile.com/firmwares/download/28243/P5210XXUANB4_P5210BTUANB1_BTU.zip/
I usually use ODIN 3.07. I assume you know the following but just in case. Remember to flash it in the PDA slot. Only have "Auto reboot" and "F. Reset time" checked.
Using Odin will reset anything the 4.4.2 builds have done to the partitions. If it doesn't work, I can only suggest to try again. When it comes to flashing, sometimes the TWRP builds for our device can be a little goofy in writing. I have not investigated completely. In the 4.2.2 roms I have flashed pimpdroid and cagrom, they seem to flash good with Moonbutt77's philz recovery with very little problems. I however cannot get 4.4 roms to flash in philz but only in TWRP. So sometimes the recovery itself seems to have a problem with the android version, or so it seems.
The above is only written from my experience on this device and cannot predict every situation.
Good luck.

Hi! Thanks for the tips.
Ufortunately, I have already tried 4.2.2 ROMS from different countries (from Sammobile): Australia (the original country of my Tab), UK, New Zealand, Belgium and US. None of them worked. I'm still downloading other ROMS but I'm startin to lose the faith... The custom ROMS I have tried, neither work and get into the bootloop.
The backup I have from TWRP is from a 4.4.2 so it's not a solution.
On the other hand, I can flash almost any 4.4.2 ROM with odin and/or TWRP. So I'm afraid I'll soon give up and I will accept that my Tab will not longer run the app I loved (Movistar TV)... Hopefully with the arrival of lollypop the developers will update the app and the bug which causes the crash will disappear.

did you wipe data in twrp? where you have to type yes to confirm?

With stock rom i dont have twrp ☺my problem is with stock rom

My problem is with stock rom. After i flash with clean install stock kdz rom 20e, my so is messed up.

I already tried factory reset after clean install and didnt work. stock 4.4.2 is ok but stock 5.0 no

when you flashed kdz did you choose cse flash?

Yes i did. Many times. It is very strange. I flashed again Android now again and everything alright because i want 5.0 fully functional

But someday i Will want stock on my g3. I even tried update 4.4.2 to 5.0 by ota and i lost WiFi. Then i made a factory reset and lost nav bar, status bar again

gc device locked
i recently bought a g3 and i factory resetted it but mcafee app locked my device and i can no longer use it , i thought flashing stock firmware would solve it because hard reset was blocked by the stupid app. im not sure but i think download mode is also blocked , how do i go back to stock then?thank you guys your help will be much appreciated.

Download Mode is Blocked?

lg apps not updating or downloading on v20h stock lollipop

is anyone having the same issue as me,
i came from kitkat and flashed v20h stock rom and supersu as per the instructions, everything works fine except my lg apps such as quickmemo+ and lg remote cannot be downloaded using the update centre,
i managed to find the apk and install, and it just doesn't let me update them either,
anyone had this problem before?

Same Boat.
Any solutions? I have the same problems after flashing to Lollipop also. However, I did make a mistake of wiping "internal storage." This is the glitch after that screwup. I resolved the other issues (no softkeys and no notification bar) by flashing Kitkat THEN LP. This issue remains, so I restored LG apps from Ti backups. but they will NOT download and/or update. They do work.
This all started because my 1st LP flash self destructed. It kinda feels like a permission thing. I am hesitant to do another reset (the right one). But I don't want to go forward until I fix this. I think the reset must do something to the LG App Updates app when you fist boot. I think it must see some stuff from internal storage that I had zapped. Since it was't there and now fails.
I know we can't be only two. problem seems rare though. So far.

Service issues after upgrading to 5.0

I upgraded from a stock rooted 4.4.2 to the OTA 5.0 using the ROM that was rooted. Some apps for my smart watch don't work in 5.0 yet, so I went TWRP and restored my backup. After booting, the phone will not get any service at all. It shows it's searching for service then gives a red "x" then starts searching again. This is process that just keeps going. I flashed the stock .tot file using the LG flash tool to get the phone completely back to stock. After doing so, the radio still won't get service. I then applied the OTA push of 5.0. After 5.0 was installed, the radio gets service without any issues. I used the LG flash tool again to go back to 4.4.2 stock and same issue; no service. Updated again to 5.0, and I get service. Any ideas on what's happening here? Is it the firmware for the radio that's having issues?

I was able to fix this by playing with the APN settings and it was able to get service, but no data. I then went back to the default t-mobile APN setting and now it works.

Same Issue
After using lg update tool to go to new 5.0 update, I put twrp back on and flashed cm12 and bliss pop rom on mine and service 100% drops out and only came back after a battery pull or a reboot, e tried to re-install roms on both and after having the same issue with the roms i tried a custom kernel issue went away and then came back, so i haven't tried AOSP since the t mobile said they'd send me another brand new phone ....but once i put everything back to OEM using the lg tool it's been 100% working again with no issues... i will try AOSP when the new phone gets here,, im thinking its kernel related

You need the new modem, boot loader, and boot images. You can't simply just flash a ROM unless all 4 (system included) is packaged as so

Upgrade broke the GPS

Hi all, I have a note 2 shg-i317 that was originally on Bell in Canada. It was unlocked and the aws mod done to it, I use freedom mobile, aka T-mobile in the states.
I was running a Rom for the past 3 years Slimfast 4.4 and liked it. I had tried Nugat on another phone, thought I would try the [ROM][7.1.2][OFFICIAL] LineageOS for N7105
I did the upgrade, broke the root, could not get a few things working, so I decided to restore the Slimfast backup I had just made (complete including modem etc) and everything works except the GPS.
GPS for me is huge, I use it a lot. I cannot lock on to 1 satellite now. Before i was able to lock onto a minimum of 16 in about 30-45 seconds, if outside.
I really dont care if I can get to 7.1 at the moment. I need my GPS back - any troublshooting for getting GPS to work on this phone?
James

I would try to flash the original stock for your phone and country from sammobile. com
Gps should work normaly then. If not your hardware is broken. If it works you can always flash your data back from your Slimfast rom.

Crap, I am posting here, because I did it again. Again not sure how. I tried to run Reserection, and I guess that messed up the GPS.
To put the original stock rom on.. I have to do that through ODIN? I dont remember how I fixed this last year.. Sorry.
Hope somone can help I need the GPS.
James
ps. Used odin 3.09 to flash the original rom... still no GPS

You flashed the latest 4.4.2 room?

The Rom that I flashed to try and restore the GPS was I317MVLUDNF1_I317MOYADNF1_BMC (mine was an originally BELL phone)
But that did not repair the GPS from me flashing resurection.. I THINK did it. I flashed an android 6 and an android 7 rom. (Mokee) but tried to go back to my Slimfast.. and the GPS was now broken.
Basically what I did a year ago.. somehow I fixed it then.. but cannot remember at all how I did it.
James

The note 2 sold by Rogers, Bell, and Telus are exactly the same model and stock roms from these carriers can be cross flashed.
Try flashing the stock ROM twice in Odin with a factory reset in between each flash.

Do you mean boot up the rom.. run the reset in the rom? or flash.. - load TWRP back in.. WIPE.. then FLASH again with odin?
Thanks for helping btw.
James

I have backups (complete all partitions) of my rom.. Slimfast 4.4 from 2-3 days ago.. when I tried this. SO.. if I can get the Factory rom to restore the GPS.. how can I restore the backup.. I saw somewhere that the EFS partition could be left out and that might help? dont restore the modem? how??
James

I meant flash with Odin, boot into stock recovery, factory reset, flash again with Odin, boot into stock recovery, factory reset, and boot into the stock ROM.

Nope, still no GPS lock.. I have the flashing circle (always had) and it will not lock.. I read about where people go into a service mode and rebuild the NV? .. I assume this is something that Mokee or Reserection did.. not sure how.
Any other ideas?
James

what about using Odin or TWRP to put different modems in? does the modem effect the GPS?
tried this.. does not seem to. grrrrr wish I knew how I fixed this.
James

I assume there are no loose wires. Does it get a lock when using wifi? Not sure what else to suggest.
Not sure about rebuilding NV.

No.. I broke it with playing with custom roms.. Liniage was last year.. I did not try that this year.. but tried both android 6 reserection and android 7 Mokee.. and I am pretty sure they messed it up.. I am also pretty sure there was something I did .. easy like load an old STOCK rom and it fixed it.. I was then able to put my slimfast 4.4 back over it and it was fine. Unfortunatly .. not enough people still using this device.. I will have to have patience I guess.
James

So I have tried differenct stock roms, but I think the issue is ODIN will not restore code from a rom image that is HARDWARE based. I wanted to use Samsung smartswitch but they disabled the part of it that allowed you to factory reset the phone, this seemed to work for several people. Many have also reported entering a code and going into a service mode.. there you can do to a menu that will rebuild hardware modules back to default. But I have not been able to get into that mode because it seems to be a touchwiz only option, and I cannot find a factory rom that is touchwiz based for this model.
What needs to be done is a true FACTORY ROM image.. that would revert all software and hardware back to original, but I cannot seem to find that anywhere.
James

The only factory roms that I know of come from places like sammobile.com and they are all based on TouchWiz which is Samsung's launcher.

So guess what? put Ressurection back on.. and the GPS is back.
I cannot get it to work in any KitKat based rom.. but now anything Marshmellow up.. works.. HMMMMMM
